BACKGROUND OF THE INVENTION

[0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. The labor object of agriculture is living animals and plants, and the products obtained are animals and plants themselves. Agriculture is the basic industry that provides support to the construction and development of the national economy.

[0003] In agricultural production, lawn grass removal devices are needed to increase the yield of crops but the existing devices are inconvenient to use for control and adjustment, and the removal effect of cutting grass and grass debris is poor, and additional manual cleaning is required which increases labor costs. Therefore, in view of the above problems, there is an urgent need to develop a lawn grass removal assistive device to overcome the shortcomings in the current practical application.

[0004] CA2296791A1 discloses a lawn mower blade that provides for single operation de-thatching, cutting and bagging of grass clippings, without necessitating the interchanging of blade s or the use of tools to return the mower to its original lawn cutting and sweeping operation.

[0020] As used herein, the singular forms "a," "an," and "the" designate both the singular and the plural, unless expressly stated to designate the singular only.

[0021] The present invention relates to a hand-held lawn grass removal assistive device that is capable of projecting a visual image on the surrounding to guide the user to choose an optimum portion over the grass surface from where scrapping of the grass layer needs to be initiated. Additionally, the proposed device also capable of providing linear reciprocating movement along the grass surface for facilitating in scrapping of layer of grass from the grass lawn as per user requirements.

[0022] Referring to Figure 1, an isometric view of a hand-held lawn grass removal assistive device is illustrated, comprising an elongated body 1 having a handle 2, free-end of the body 1 arranged with a circular member 3, straps 4 attached with the body 1, motorized rollers 5 integrated within the body 1 and straps 4, artificial intelligence-based imaging unit 6 mapped on the body 1, touch interactive display panel 7 mapped on the body 1, holographic projection unit 8 mapped on the body 1, motorized slider crank arrangement 9 assembled on free-end of the body 1, rectangular plate 10 integrated on the arrangement 9 and a speaker 11 mapped on the body 1.

[0023] The proposed device includes an elongated body 1 having a handle 2 that is accessed by a user for acquiring a grip over the body 1, wherein free-end of the body 1 is arranged with a circular member 3 that is positioned by the user in proximity to a grass lawn. Moreover, a pair of straps 4 attached with the body 1 for securing the body 1 around palm portion of the user in order to secure the body 1 on the palm portion. Wherein, an inbuilt microcontroller actuates multiple pressure sensors installed on the body 1 and straps 4 for detecting pressure applied by the body 1 and straps 4 on the palm portion. The multiple pressure sensors used herein ranges from (2 to 4).

[0024] The pressure sensors comprises of a sensing element known as diaphragm that experiences a force applied by the body 1 and the straps 4 on the palm portion. This force leads to deflection in the diaphragm that is measured by the sensors and converted into an electrical signal which is sent to the microcontroller for determining the pressure applied by the body 1 and the straps 4 over the palm portion. Based on the detected pressure, the microcontroller actuates a pair of motorized rollers 5 integrated within the body 1 and straps 4 for rotating on axis to properly fit the body 1 and straps 4.

[0025] The motorized rollers 5 consists of a cylindrical member 3 and a motor. The microcontroller actuates the motor to generate electrical current that drives the cylindrical member which further assists the rollers 5 to rotate on axis as to properly fit the body 1 and straps 4. Further, the microcontroller actuates an artificial intelligence-based imaging unit 6 mapped on the body 1 and paired with a processor for capturing and processing multiple images of surroundings, wherein the microcontroller based on the processed images generates a 3D (three-dimension) mapping of the surroundings.

[0026] The imaging unit 6 comprises of an image capturing arrangement including a set of lenses that captures multiple images of the surroundings and the captured images are stored within memory of the imaging unit 6 in form of an optical data. The imaging unit 6 also comprises of a processor that is integrated with artificial intelligence protocols, such that the processor processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and are further transmitted to the microcontroller. The microcontroller processes the received data and the microcontroller based on the processed images generates a 3D (three-dimension) mapping of the surroundings. The microcontroller actuates a touch interactive display panel 7 mapped on the body 1 for displaying the evaluated mapping that is further accessed by the user to select a portion of the grass lawn where the user desires to perform grass removal operation over the grass lawn.

[0027] When the user accesses the touch interactive display panel 7 to select a portion of the grass lawn where the user desires to perform grass removal operation over the grass lawn, then an internal circuitry of the display panel 7 senses those touches of the user and synchronically, the internal circuitry automatically converts the touch responses into electric signals and then transmits those signals to the microcontroller. The microcontroller further analyses the signals and actuates the display panel 7 to enable the user to select a portion of the grass lawn where the user desires to perform grass removal operation over the grass lawn. Wherein based on the user-specified portion the microcontroller actuates a holographic projection unit 8 mapped on the body 1 to project a visual image on the surrounding to guide the user to position the body 1 at an optimum portion over the grass surface.

[0028] The holographic projection unit 8 comprises of holograms, shutter, beam splitters, diverging lenses and a mirror utilized to project holograms. Firstly, the projector emits the laser beam and passed through the shutter to impact on the beam splitter. After the impact of laser beam, the splitter splits the laser beam into two directions. First part is shone through a diverging lens where it scatters to impact on the mirror and produce reflected beam and another part is passed to another mirror directly where it reflects the beam and pass through another diverging lens. After then, the reflected beam from first part falls on an evaluated pattern produce an image. Lastly, the projector compares the resultant beams and produce visual images for highlighting a suitable gap for guiding the user to position the body 1 at an optimum portion over the grass surface.

[0029] Moreover, a motorized slider crank arrangement 9 assembled on free-end of the body 1 that is actuated by the microcontroller for providing linear reciprocator movement to a rectangular plate 10 integrated on the arrangement along the grass surface, thereby facilitating in scarping of layer of grass from the grass lawn via sharp-edged tip of the plate 10.

[0030] The motorized slider crank arrangement 9 consists of three main components that is a crank, connecting rod, and a slider, wherein the crank is powered by a DC (Direct Current) motor. The crank is a rotating shaft driven by a motor or other power source. The connecting rod is a linear link that connects the crank to the slider. The slider is a sliding element that moves back and forth along a straight line. As the crank rotates, it drives the connecting rod and slider through a series of pivot points, causing the slider to move back and forth that is in a reciprocating motion which is connected to the crank gear. The speed and distance of the slider movement can be controlled by adjusting the connecting rod length, the crank speed, or the pivot point's position. Thus, the slider crank arrangement 9 the converts the rotational motion to a reciprocating motion to the crank gear integrated in arrangement which in turn induces a reciprocating to and fro movement to the rectangular plate 10 integrated on the arrangement along the grass surface, thereby facilitating in scarping of layer of grass from the grass lawn via sharp-edged tip of the plate 10.

[0031] After the successful scrapping of grass layer from the surface, the microcontroller activates a speaker 11 mapped on the body 1 for notifying the user to deploy the scrapped grass layer in proximity to the body 1 as per their convenience. The speaker 11 comprises of a voice coil and a permanent magnet. The microcontroller actuates the speaker 11 thereby generating electrical current via the voice coil which further produces an electric field that interacts with the magnetic field of the permanent magnet attached to the speaker 11. Due to attraction and repelling of like charges with each other, an audio signal is sent via the voice coil due to which, a musical waveform is produced that moves up and down, the voice coil gets attracted and repelled by the permanent magnet. Due to attraction and repelling of the voice coil by the permanent magnet, a cone attached with the voice coil moves back and forth creating pressure waves in the air perceiving as voice commands from the speaker 11 to generate audio alerts to produce audio signals to produce audio notification for the user to deploy the scrapped grass layer in proximity to the body 1 as per their convenience.

[0032] Furthermore, the battery (not shown in fig.) is installed with the device to power all electrical and electronic component necessary for their operation. The battery is linked to the microcontroller and provides (DC) Direct Current to the microcontroller. And then, based on the order of operations, the microcontroller sends that current to those specific electrical or electronic components so they effectively carry out their appropriate function.

[0033] The proposed device works best in the following manner, the proposed device includes the elongated body 1 having a handle 2 that is accessed by a user for acquiring a grip over the body 1, wherein the circular member 3 is positioned by the user in proximity to a grass lawn and the straps 4 secure the body 1 around palm portion of the user in order to secure the body 1 on the palm portion. The motorized rollers 5 for rotating on its axis to properly fit the body 1 and straps 4 and the artificial intelligence-based imaging unit 6 captures images of surroundings and generates a 3D (three-dimension) mapping of the surroundings. The touch interactive display panel 7 displays the evaluated mapping that is further accessed by the user to select a portion of the grass lawn where the user desires to perform grass removal operation over the grass lawn. The holographic projection unit 8 project a visual image on the surrounding to guide the user to position the body 1 at an optimum portion over the grass surface and the motorized slider crank arrangement 9 for providing linear reciprocator movement to a rectangular plate 10 along the grass surface thereby facilitating in scarping of layer of grass the grass lawn via sharp-edged tip of the plate 10.
