Description

Technical Field

[0001] The present invention relates to the technical field of agricultural equipment, and in particular to a multi-functional pesticide spraying device. Background Art

[0002] When the existing pesticide spraying devices are used for removing weeds in farmland, they usually mainly rely on spraying a single herbicide; this method mainly depends on chemical means, by spraying pesticides or specific herbicides to kill or inhibit the growth of weeds. The advantages of this method are relatively simple operation, wide coverage area, and the ability to process a large area of farmland in a short time;

[0003] Among them, for a Chinese patent "An agricultural pesticide spraying device with a weeding function" with the application number "202021714852.4", this patent includes a medicine spraying tank, a driving structure, a weeding device, a medicine spraying device and a storage structure. The driving structure is installed on the inner bottom wall of the medicine spraying tank through a support frame. A medicine tank is installed on the inner bottom wall of the medicine spraying tank, and the medicine tank is located on one side of the driving structure. The weeding device is installed at the bottom of the medicine spraying tank. The medicine spraying device is installed through the upper part of the medicine spraying tank. The storage structure is installed above the medicine spraying tank, and the storage structure is located on one side of the medicine spraying device. By installing a weeding device, the weeding device can cut and process the weeds at the low positions on both sides during the process of the device moving forward, thus completing the first weeding process and providing a more convenient removal environment for the subsequent chemical weeding process, so that the sprayed pesticide liquid can directly contact the roots of the weeds, maximizing the efficacy of the medicine and enhancing the weeding effect of the device.

[0004] The above patent combines a weeding device and a medicine spraying device, and proposes a multi-functional pesticide spraying device that can directly contact the roots of weeds with pesticide liquid. However, the above patent has the following defects;

[0005] 1. The overall device has low applicability. Integrating the weeding device and the medicine spraying device on the driving structure is not convenient for small-scale use;

[0006] 2. For small-scale use, the current solution to the above patent is to first cut with a cutting machine, push aside the cut weeds, and finally spray the roots through a pesticide spraying device;

[0007] Through 2, the following defects are generated:

[0008] 3. The integration degree of the small processing device is not high, and it cannot simultaneously cut weeds, push aside the cut weeds, and spray pesticides to the roots of the weeds;

[0009] Due to the deficiencies of 1, 2, and 3, in this case, the weeding mechanism, the grass skimming mechanism (skimming the grass), and the spraying mechanism are integrated and improved, so as to provide a multi-functional pesticide spraying device to meet the above deficiencies and achieve a better weeding effect. Summary of the Invention

[0010] The purpose of the present invention is to provide a multi-functional pesticide spraying device to solve the above deficiencies in the technology.

[0011] To achieve the above purpose, the present invention provides the following technical solution: A multi-functional pesticide spraying device includes a device fixing seat, a weeding mechanism, a grass skimming mechanism, and a spraying mechanism. The weeding mechanism is located at the front end of the device fixing seat, the grass skimming mechanism is arranged at the bottom of the device fixing seat, and the spraying mechanism is installed at the rear end of the device fixing seat;

[0012] The weeding mechanism includes a cutting bin. Two groups of cutting bins are symmetrically arranged on both sides of the front end of the device fixing seat. A cutting main shaft is arranged in each cutting bin. A driving box is arranged between the cutting bins. Grass collecting plates are symmetrically arranged outward on the outside of the cutting bins. An inspection cover is installed at the top of the cutting bin, and a blocking structure is arranged at the front end of the inspection cover;

[0013] The driving mechanism of the cutting main shaft is installed in the device fixing seat and the driving box;

[0014] The grass skimming mechanism includes a grass skimming frame and an air duct. The grass skimming frame is installed at the front end of the bottom of the device fixing seat, and the air duct extends inside the device fixing seat to the bottom and is located at the rear end of the grass skimming frame;

[0015] The spraying mechanism includes a spraying frame, and a plurality of pesticide atomizing nozzles are installed at the bottom of the spraying frame.

[0016] As a preferred solution of the present invention, the side of the cutting bin close to the device fixing seat is designed in a semi-circular arc structure, and a hollow groove is opened at the bottom. A blocking frame is installed in the hollow groove to internally place the cutting main shaft.

[0017] As a preferred solution of the present invention, weed cutting blades are installed on the periphery of the cutting main shaft, and the side of the cutting main shaft away from the driving box is rotatably connected to the shaft seat on the inner wall of the cutting bin.

[0018] As a preferred solution of the present invention, the grass collecting plates between the two cutting bins form a guiding triangle, and the other two groups of grass collecting plates extend outward. A baffle plate arranged obliquely upward is provided at the front end of the inspection cover above the grass collecting plates, and the inspection cover is fixed to the cutting bin by bolts.

[0019] As a preferred embodiment of the present invention, the barrier structure is composed of several groups of blocking rods, the blocking rods are arranged at equal intervals, a fork rod is provided at the front end of the bottom of the blocking rod, and the fork rod forms a semi-circular arc structure at the front end of the blocking rod. The barrier structure is installed at the bottom of the grass blocking plate.

[0020] As a preferred embodiment of the present invention, the driving mechanism includes a driving motor, the driving motor is installed in the device fixing seat, a driving bevel gear is installed at the output end of the driving motor, and driven bevel gears are installed on both sides of the driving box. The driving motor operates to drive the driving bevel gear to rotate, and then the engaged driven bevel gears rotate.

[0021] As a preferred embodiment of the present invention, the grass skimming frame is designed in an "L" structure, a wind direction guiding plate is installed at the end of the air duct, and the air duct is connected to a blower connected externally through an air pipe installed at the top of the device fixing seat.

[0022] As a preferred embodiment of the present invention, moving wheels are symmetrically installed at the bottom of the grass skimming frame.

[0023] As a preferred embodiment of the present invention, a spray pipe is provided inside the spray frame, and the spray frame is installed on the device fixing seat through a connecting frame.

[0024] As a preferred embodiment of the present invention, an installation frame is provided at the top of the device fixing seat. The liquid supply pipe for the spray frame and the power supply line of the driving mechanism are built inside the installation frame, and the installation frame is used to connect to a handheld part or a mobile device.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] With the device fixing seat as the foundation and support structure of the whole device, the device fixing seat ensures the stability and reliability of the device. It bears the weeding mechanism, the grass skimming mechanism and the spraying mechanism, enabling these parts to work together;

[0027] For the weeding mechanism, we designed a cutting bin, a grass collecting plate and a maintenance cover to form a safe cutting space. The guiding triangular structure formed by the grass collecting plate helps to guide the cut weeds into the cutting bin. The cutting bin is internally provided with a horizontal cutting main shaft, combined with a driving structure, to efficiently cut the weeds. At the same time, the barrier structure protects the front end, preventing large soil blocks and stones from hitting the inside, and forms a semi-circular arc structure, allowing the soil blocks and stones to flow out along both sides, avoiding damage to the cutting blades;

[0028] For the weed skimming mechanism, we designed it at the bottom of the device fixed seat. First, the cut weeds are preliminarily skimmed through the "L"-shaped weed skimming frame, enabling the effective skimming of the cut weeds and creating conditions for subsequent pesticide spraying. Then, the relatively small and fragmented weeds are blown to both sides through the air duct at the rear end, avoiding obstruction to the grass roots and enhancing the pesticide spraying effect.

[0029] Finally, in combination with the layout of the rear spraying mechanism, pesticide spraying is carried out.

[0030] Combined with the above, this pesticide spraying device has a high degree of integration, integrating the functions of weed removal, weed skimming, and spraying in one device, simplifying the operation process, improving work efficiency, and the overall device is reasonably designed, with each part working in coordination, enabling the operator to easily control the entire weed removal and spraying process. Through the optimized cutting bin design and drive mechanism, weeds can be cut efficiently and accurately, and it is suitable for small-scale weed removal use. Brief Description of the Drawings

The spraying mechanism 4 includes a spraying frame 41. The spraying frame 41 is connected to a drug pressurizing pipeline. A plurality of pesticide atomizing nozzles 42 are installed at the bottom of the spraying frame 41, and pesticides are atomized and sprayed through the pesticide atomizing nozzles 42.

[0049] Embodiment 2

[0050] As Figures 1-5 shown in the figure, one side of the cutting bin 21 close to the device fixing base 1 is designed in a semi-circular arc structure to adapt to the weed cutting blade 221, and a hollow groove 211 is opened at the bottom. The hollow groove 211 is used for discharging the crushed weeds. A blocking frame 212 is installed in the hollow groove 211, and then the cutting main shaft 22 is housed inside.

[0051] Weed cutting blades 221 are installed on the periphery of the cutting main shaft 22. The length of the cutting main shaft 22 and the number of the weed cutting blades 221 are designed according to requirements. One side of the cutting main shaft 22 far from the driving box 23 is rotationally connected to a shaft seat on the inner wall of the cutting bin 21, thereby providing a stable cutting main shaft 22.

[0052] The grass collecting plates 24 between the two cutting bins 21 form a guiding triangle, so that the weeds are guided into the cutting bins 21 on both sides. The other two groups of grass collecting plates 24 extend outward. A baffle 251 arranged obliquely upward is provided at the front end of the inspection cover 25 above the grass collecting plates 24. The baffle 251 is used to lower the height of the grass, and the inspection cover 25 is fixed to the cutting bin 21 by bolts, which is convenient for inspecting and maintaining the inside of the cutting bin 21.

[0053] The blocking structure 5 is composed of several groups of blocking rods 51. The blocking rods 51 are arranged at equal intervals. A fork rod 52 is provided at the front end of the bottom of the blocking rod 51, and the fork rod 52 forms a semi-circular arc structure at the front end of the blocking rod 51. The blocking structure 5 is installed at the bottom of the baffle 251.

[0054] The driving mechanism 6 includes a driving motor 61, which is installed in the device fixing base 1. The output end of the driving motor 61 is equipped with a driving bevel gear 62. The two sides of the driving box 23 are equipped with driven bevel gears 63. The operation of the driving motor 61 drives the driving bevel gear 62 to rotate, and then meshes with the connected driven bevel gears 63 to rotate.

[0055] The weed skimmer 31 is designed in an "L" structure. A wind direction guiding plate 33 is installed at the end of the air duct 32, and the air duct 32 is connected to a blower connected externally through an air pipe 34 installed at the top of the device fixing base 1.

[0056] Symmetrically installed moving wheels 35 are also installed at the bottom of the weed skimmer 31. When held by hand, the moving wheels 35 can place the entire device on the ground and can also assist in proper sliding on the soil.

[0057] The inside of the spraying frame 41 is provided with a spraying pipeline, and the spraying frame 41 is installed on the device fixing base 1 through a connecting frame.

[0058] An installation frame 11 is provided at the top of the device fixing base 1. The inside of the installation frame 11 houses the liquid supply pipeline for the spraying frame 41 and the power supply line for the driving mechanism 6. The installation frame 11 is used to connect to the handheld part or a mobile device. Since the device needs to be connected to an external liquid supply system, namely a medicine box and a pump, as well as an external power source and a blower, handheld operation can be achieved through an extended pressure pipeline, an external power cord, and a blower pipeline. The device can also be integrated on a mobile device such as a trolley or a flatbed cart, and all can achieve and perform small-range operations.

[0059] The working process of the present invention: When using a multifunctional pesticide spraying device, first ensure that all parts of the device are correctly installed and in working condition. The weeding mechanism 2 is at the front end of the device fixing base and includes a cutting bin 21 and a driving mechanism. After the driving motor 61 of the driving mechanism 6 starts, the driving bevel gear 62 drives the driven bevel gear 63 to rotate, and then drives the cutting main shaft 22 to drive the peripheral weed cutting blades 221 to work. When the device moves forward, the blocking structure 5 can prevent large debris or stones from entering the cutting bin 21. The grass collecting plate 24 and the grass guiding plate 251 guide the weeds into the cutting bin 21, and the weed cutting blades 221 cut the weeds and the cut weeds fall into the cutting bin 21. When the weeding mechanism 2 finishes cutting the weeds, the weed skimmer 31 guides the weeds to both sides. At the same time, the external blower connected to the air duct 32 operates, and through the air duct 32 and the wind direction guiding plate 33, the small weeds are pushed aside or blown away. When the weeding and weed skimming work is completed, the spraying mechanism 4 starts to work, and the pesticide is evenly sprayed onto the roots of the weeds through the spraying pipeline of the spraying frame 41 and the pesticide atomizing nozzle 42, thus completing the pesticide spraying process.

[0060] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
