[0022] Furthermore, the conveyor belt is sleeved between two rollers, and a driving sprocket is provided at the end of any roller, and the driving sprocket is connected to the sprocket on the power output end of the roller driving mechanism through a conveyor belt chain.

[0023] The beneficial effect of adopting the above further solution is that the driving mechanism provides power to the roller, so that the roller drives the conveyor belt to move.

[0024] Furthermore, the overall shape of the fork frame is a triangular plate shape.

[0025] The beneficial effect of adopting the above further solution is that it is easy to obtain a single row of crops from the crop planting site for cutting. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The inventive concept of the present invention:

[0051] To address these challenges, we developed a new technology: a harvesting mechanism is located at the front of the vehicle body, ensuring efficient and convenient harvesting operations. A tilted conveyor belt is installed in the middle section, optimizing space utilization. This space is used to house batteries and the entire machine's control circuit board, further improving overall performance. Furthermore, a storage basket is located at the rear of the vehicle body. This basket can be used to store both harvested crops and pesticides during spraying, integrating harvesting and storage, significantly improving operational efficiency. The spraying mechanism is located at the rear of the vehicle body. The pesticide is supplied via the inlet pipe of a high-pressure water pump, and the outlet pipe is connected to the spray nozzle via a hose, ensuring efficient and uniform spraying. Furthermore, the slider assembly and wheel assembly designed for the drive wheel mechanism are fixed to the side of the vehicle body, while the wheel assembly is fixed to the slider of the slider assembly. This allows for adjustable wheel height, thus adjusting the chassis height. When in use, the chassis height can be adjusted according to the height of the crops to adapt to different working environments and improve the passability and stability of the machine. Example

[0052] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 as well as Figure 11 As shown, a small-sized crop spraying and harvesting machine includes a body structure 100. A harvesting mechanism 200 is provided at the front end of the body structure 100, a spraying mechanism 300 is provided at the rear end, and a transport mechanism 400 is provided in the middle. One end of the transport mechanism 400 is connected to the rear of the harvesting mechanism 200, and the other end is connected to the top of the spraying mechanism 300.

[0053] The vehicle body structure 100 includes two vertically arranged side body panels 101 , and the front and rear areas of the two side body panels 101 are respectively provided with height-adjustable driving wheel mechanisms 500 ;

[0054] The harvesting mechanism 200 includes a pair of front forks 201, with a thumbwheel assembly 202 disposed behind the two front forks 201. The rear sections of the two front forks 201 and the area covered by the thumbwheel assembly 202 constitute a crop harvesting area. Rotating cutting tools 204 are disposed on the sides of the crop harvesting area. The cutting tools 204 are located below the thumbwheel assembly 202, and the horizontal length of the blades of the cutting tools 204 covers the crop harvesting area.

[0055] The spraying mechanism 300 includes a storage basket 301 and a nozzle 305 , and the storage basket 301 and the nozzle 305 are connected by a medicine tube 306 ;

[0056] The transport mechanism 400 includes a conveyor belt 401;

[0057] The driving wheel mechanism 500 includes a sliding assembly and a wheel assembly; the wheel assembly is movably disposed on the sliding assembly.

[0058] The front end of the carriage of the present invention is provided with a harvesting mechanism, which hooks the crops through the thumbwheel assembly of the harvesting mechanism, and then harvests them through the cutting tool. After harvesting, the thumbwheel assembly rotates and moves the crops to the conveyor belt, and the conveyor belt transports the crops to the storage basket to achieve storage of the crops. When it is necessary to spray medicine, the medicine solution is placed in the storage basket, and the medicine solution is connected to the medicine pipe, and connected to the nozzle through the water pump to achieve the function of spraying medicine on the crops. At the same time, in order to make the harvesting and spraying of medicines automatic, a driving wheel mechanism is configured. The driving wheel mechanism consists of a sliding assembly and a wheel assembly. The height of the wheel can be adjusted, and then the height of the chassis can be adjusted to adapt to different heights of crops and different planting terrains. The entire body of the present invention is small and low in cost, but it integrates the functions of harvesting, conveying, storing and spraying pesticides, and is fully suitable for small-scale planting.

[0059] In some embodiments, an upper connecting plate 205 and a lower connecting plate 206 are provided on the rear side of the fork frame 201. Mounting holes are provided on both the upper connecting plate 205 and the lower connecting plate 206, and the fork frame 201 is secured to the mounting frame 102 at the front end of the vehicle body structure 100 via the upper connecting plate 205 and the lower connecting plate 206. The center rod 207 of the thumbwheel assembly 202 passes through the mounting holes and is positioned between the upper connecting plate 205 and the lower connecting plate 206, thereby allowing the thumbwheel assembly to be mounted on the mounting frame 102 at the front end of the vehicle body structure 100. The thumbwheel blade 203 is sleeved on the center rod 207 and positioned between the upper connecting plate 205 and the lower connecting plate 206. A thumbwheel blade clearance slot is formed between the upper connecting plate and the lower connecting plate, utilizing the mounting space of the fork frame 201 and contributing to a smaller overall size.

[0060] The length of the upper connecting plate 205 and the lower connecting plate 206 is greater than the radius of the thumbwheel blade, ensuring normal rotation of the thumbwheel blade. The thumbwheel blade 203 is crescent-shaped to ensure that the thumbwheel blade can hook the crop. The thumbwheel assembly is equipped with one or more thumbwheel blades. In this embodiment, two thumbwheel blades are provided, one above and one below, mirrored in arrangement.

A tool drive mechanism 401 is provided on the upper surface of the transverse plate, and the power output of the tool drive mechanism 208 passes through the transverse plate and connects to the cutting tool 204. This structure allows the thumbwheel blades to engage the crop within the space between the two forks while the cutting tool can completely cut the crop from below, ensuring efficient crop cutting. This also allows the actions of engaging and cutting the crop to be accomplished within the minimum space possible, reducing the overall size of the machine.

[0062] In some embodiments, in order to facilitate the fixation of the fork frame provided with the driving mechanism 401 to the mounting frame 102 at the front end of the vehicle body structure 100, the vertical portion of the L-shaped connecting plate is provided on the rear surface of the fork frame, and the horizontal plate is positioned lower than the lower surface of the fork frame; a vertical mounting plate with a flange 210 is provided on the other side of the horizontal plate; a mounting hole is provided on the flange 210 of the vertical mounting plate, and the flange 210 is fixed to the mounting frame 102 by means of bolts engaging with the mounting holes.

[0064] In some embodiments, the conveyor belt 401 is tilted upward, with the lower end of the conveyor belt 401 connected to the thumbwheel blades and the higher end positioned above the storage basket 301. This tilted conveyor belt can better utilize the height space of the vehicle body, allowing the battery and control circuit board for the entire machine to be placed in the space below the conveyor belt, and also to accommodate the motor that drives the conveyor belt. In some embodiments, this space can be utilized to reduce the size of the vehicle body.

[0065] In some embodiments, to ensure the conveyor belt is powered and capable of rotating, a conveyor belt 401 is mounted between two rollers positioned between two side panels 101. A first driving sprocket is provided at the end of each roller.

Specifically, a roller drive mechanism 403 is positioned below the conveyor belt. After its power output end passes through the side panels, a driving sprocket is provided at its end. This driving sprocket is connected to the driving sprocket at the roller end via the conveyor belt chain, thereby providing power for the conveyor belt.

[0066] In some embodiments, the overall shape of the fork frame 201 is a triangular plate shape, which is helpful for selecting a portion of crops from a patch of crops and preparing for the thumbwheel blades to hook onto a single crop.

[0067] In some embodiments, a storage basket 301 is positioned at the rear of the vehicle body 100. A nozzle mounting assembly is provided at the rear of the vehicle body 100.

Both ends of the mounting bar 308 are fixedly connected to the two side panels 101. When spraying pesticides, the pesticide bottle is placed in the storage basket and connected to the water outlet pipe at the bottom of the storage basket. Then, with the cooperation of the water pump, medicine pipe, and nozzle, water can be sprayed on crops from the rear of the vehicle.

[0068] In some embodiments, in order to ensure the atomization effect of the sprayed medicine and maximize the spraying range of the medicine, the nozzle 305 is divided into a water inlet part 308 and an atomization part 307, an atomization filter element 310 is provided between the water inlet part 308 and the atomization part 307, and the atomization part 307 is a conical water outlet cavity from the inside to the outside.
