Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically a spraying device for pest control in spring rapeseed fields. Background Technology

[0002] In modern agricultural production, cash crops such as spring rapeseed are often attacked by various pests. These pests not only pose a direct threat to crop growth but may also spread diseases, leading to reduced crop yields. Therefore, timely and effective pest control has become an important means to ensure crop growth. In the process of control, pesticide spraying is a commonly used method, which can effectively distribute pesticides evenly on the plant surface to achieve the purpose of killing insects and preventing diseases. However, in the existing technology, manual sprayers are usually used to spray spring rapeseed fields. This operation method consumes a lot of manpower and has low work efficiency. Although there are some electric spraying devices in the existing technology (such as the pest control spraying device disclosed in announcement number CN 213523595 U), they still have the drawbacks of complex structure and inconvenient maintenance.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 — Figure 6 A spraying device for pest control in rapeseed fields includes a push trolley, a storage tank 200, a motor 500, and a piston feeding mechanism 300. The push trolley includes a push handle 101, a base 102, and shock-absorbing wheels 103. The push handle 101 is fixedly connected to the base 102, and multiple sets of shock-absorbing wheels 103 are fixedly connected to the bottom of the base 102.

[0027] Furthermore, a medicine storage tank 200 is fixedly connected to the base 102, and a stirring paddle 201 is rotatably connected to the medicine storage tank 200. A piston feeding mechanism 300 is also provided on one side of the medicine storage tank 200. Specifically, the piston feeding mechanism 300 includes a piston cylinder 301, a piston disc 302, and a driving component 303. That is, a piston cylinder 301 is fixedly connected to one side of the medicine storage tank 200, a piston disc 302 is provided inside the piston cylinder 301, an inlet pipe 304 is fixedly connected to the bottom end of the piston cylinder 301, an outlet pipe 305 is fixedly connected to the outer side of the piston cylinder 301, a one-way valve A 306 is fixedly connected to the inlet pipe 304, a one-way valve B 307 is fixedly connected to the outlet pipe 305, a piston column 308 is fixedly connected to the piston disc 302, and a driving component 303 is also provided on the medicine storage tank 200. The driving component 303 is matched with the piston column 308.

[0028] In addition, a spraying component 400 is fixedly connected to the push trolley, and an extraction pipe 202 is fixedly connected to the medicine storage tank 200. The aforementioned liquid inlet pipe 304 is connected to the extraction pipe 202 through pipe A309, and the liquid outlet pipe 305 is connected to the spraying component 400 through pipe B310.

[0029] Furthermore, a motor 500 is fixedly connected to the medicine storage tank 200. The motor 500 is powered by the stirring paddle 201 and the drive component 303, so that the motor 500 can drive the stirring paddle 201 to rotate. At the same time, the motor 500 can also drive the piston column 308 to drive the piston disc 302 to move up and down reciprocally through the drive component 303.

[0030] Furthermore, in this embodiment, the driving component 303 includes a rotating disk 311, a traction arm 312, and a power input shaft 313. Specifically, a power input shaft 313 is rotatably connected to the medicine storage tank 200, and one end of the power input shaft 313 is fixedly connected to the rotating disk 311. An eccentric shaft 314 is fixedly connected to the rotating disk 311. A traction member 315 is fixedly connected to the top end of the piston rod 308, and a traction arm 312 is rotatably connected to the eccentric shaft 314. One end of the traction arm 312 is rotatably connected to the traction member 315. On the lead-in component 315, the power input shaft 313 is connected to the motor 500. When the motor 500 drives the rotating disk 311 to rotate, under the action of the traction arm 312, it can drive the piston rod 308 to move up and down, which causes the piston disk 302 to move up and down reciprocally inside the piston cylinder 301. When the piston disk 302 moves up and down reciprocally, in conjunction with the one-way valve A306 and one-way valve B307, the liquid medicine in the medicine storage tank 200 can be pumped to the spraying component for spraying, thereby realizing the spraying operation.

[0031] Furthermore, the aforementioned spraying component 400 includes a mounting bracket 401, a spray head 402, and a connecting pipe 403. Specifically, a mounting bracket 401 is fixedly connected to the base 102, and multiple sets of spray heads 402 are fixedly connected to the mounting bracket 401. The spray heads 402 face downwards and are located on the side of the pusher trolley. All sets of spray heads 402 are fixedly connected to the connecting pipe 403, which is connected to the pipeline B310. This means that when the piston disc 302 descends, it pushes the agent in the piston cylinder 301 to the connecting pipe 403, and finally sprays the liquid onto the rapeseed through the spray head 402.

[0032] Furthermore, a worm gear 600 is fixedly connected to the shaft of the stirring paddle 201, and a worm 700 is rotatably connected to the storage tank 200. The worm 700 meshes with the worm gear 600, and the motor 500 is powered by the worm 700. The worm 700 is powered by the power input shaft 313 through the transmission component A. In this way, the motor 500 can drive the worm 700 to rotate, which in turn drives the worm gear 600 to rotate, thereby causing the stirring paddle 201 to rotate. The worm 700 and the worm gear 600 can also increase torque to ensure the stirring force of the stirring paddle 201. The power of the worm 700 can also be transmitted to the rotating disk 311, causing the rotating disk 311 to rotate. In this way, one set of motors 500 can provide power for the entire device, reducing the number of power sources and making maintenance easier.

[0033] The aforementioned transmission component A includes a drive pulley A801, a driven pulley A802, and a transmission belt A803. Specifically, the driven pulley A802 is fixedly connected to the power input shaft 313, the drive pulley A801 ​​is fixedly connected to the worm gear 700, and the driven pulley A802 and the drive pulley A801 ​​are connected by the transmission belt A803.

[0034] In a further optimized embodiment, two sets of piston feeding mechanisms 300 are used. Simultaneously, two sets of spraying components 400 and extraction pipes 202 are matched. The spray heads 402 of the two sets of spraying components 400 are located on both sides of the push trolley. In the two sets of piston feeding mechanisms 300, the two sets of power input shafts 313 are connected by a transmission component B. In this way, the motor 500 can drive the two sets of rotating disks 311 to rotate, which makes the two sets of piston disks 302 reciprocate up and down in the corresponding piston cylinders 301, thereby pumping the liquid medicine in the storage tank 200 to the spray heads 402 on both sides for spraying. This allows the rapeseed on both sides to be sprayed at one time, thereby speeding up the work efficiency. Moreover, the piston feeding mechanism 300 can ensure the stability and uniformity of liquid medicine delivery, avoid uneven liquid medicine supply, and enhance the spraying effect.

[0035] The aforementioned transmission component B includes a drive pulley B901, a driven pulley B902, and a transmission belt B903. Specifically, a driven pulley A802 is fixedly connected to one set of power input shafts 313, and a drive pulley B901 is fixedly connected to another set of power input shafts 313. The driven pulley B902 and the drive pulley B901 are connected by a transmission belt B903.
