Description

Technical Field

[0001] This utility model relates to the field of agricultural pest and disease control technology, specifically to a pesticide spraying device for agricultural pest and disease control. Background Technology

[0002] In agricultural production, pesticide spraying devices are key equipment for controlling pests and diseases. They are typically used to evenly and accurately spray pesticides, fungicides, herbicides, and other agents onto the crop surface or growing environment. In short, pesticide spraying devices for agricultural pest and disease control aim for efficient atomization, uniform spraying, and intelligent control. They are classified according to different scenarios and require careful maintenance to achieve efficient, safe, and low-environmental-impact control effects.

[0003] In the prior art, when drugs are mixed with water, they tend to coagulate, affecting the uniformity of the mixture.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN214178791U) discloses a portable pesticide spraying device for agricultural pest and disease control, including a pesticide box, a fixed frame, and a stirring rod. A clamping frame is installed on one side of the pesticide box, and a sealing frame is installed on one side inside the pesticide box. A water pump is installed inside the sealing frame, and a first water pipe is installed through the sealing frame at the input end of the water pump. A fixed frame is installed at the top of the pesticide box, and a sealing block is installed inside the fixed frame. A sleeve is installed inside the sealing block through a bearing, and a fixing frame is installed at the top of the sealing block. In this portable pesticide spraying device for agricultural pest and disease control, a first transmission wheel drives a rotating rod to rotate clockwise. The rotating rod drives a first gear and a second gear to mesh and rotate. The second gear then drives the sleeve to rotate in the opposite direction, thereby facilitating thorough stirring of the pesticide solution in the pesticide box and making the pesticide more evenly stirred.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation. For example, if there are many undissolved particles inside the device during drug spraying, the drug particles can easily clog the spray nozzle, affecting the stability of drug spraying. Utility Model Content

[0006] The purpose of this utility model is to provide a pesticide spraying device for the control of agricultural pests and diseases, so as to solve the problem mentioned in the background art that if there are a lot of undissolved particles inside the device during pesticide spraying, the pesticide particles will easily clog the spray nozzle and affect the stability of pesticide spraying.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an agricultural pest and disease control spraying device, comprising a body and a shoulder strap at the front end of the body, and a feeding port on the right side of the body, a mixing rod rotatably mounted inside the body, a drive rod rotatably mounted on the left inner wall of the body, and an anti-clogging mechanism at the lower end of the drive rod, and a positioning plate fixedly mounted on the left outer wall of the body, with a convenient storage mechanism at the front end of the positioning plate.

[0008] Furthermore, a telescopic bellows is connected to the left side of the machine body, and a pressure pump is installed at the middle end of the telescopic bellows. The right end of the pressure pump is fixedly installed on the left side of the machine body, and a handheld spray pipe is connected to the front end of the telescopic bellows.

[0009] Furthermore, the upper end of the mixing rod is connected to the output end of the motor, and the motor is located on the upper inner wall of the machine body.

[0010] Furthermore, the anti-clogging mechanism is provided with a receiving sleeve, and the left side of the receiving sleeve is connected to the bottom of the telescopic corrugated pipe, and a cleaning brush is fixedly installed on the inner wall of the right side of the receiving sleeve.

[0011] Furthermore, the upper end of the drive rod forms a synchronous rotation structure with the upper end of the mixing rod through a belt and pulley, and a housing is fixedly installed at the bottom of the drive rod. A cleaning brush is nested inside the housing, and a pressure spring is provided between the cleaning brush and the housing. The end of the cleaning brush is inclined and corresponds to the surface of the filter screen.

[0012] Furthermore, the convenient storage mechanism is equipped with a locking block, and the rear end of the locking block is installed through the surface of the internal guide rod of the positioning plate. A handle is provided on the left side of the locking block, and the right side of the locking block is inclined. The locking block corresponds to the handheld nozzle.

[0013] Furthermore, a support plate is fixedly installed at the middle end of the handheld nozzle, and the lower end of the support plate is located at the upper end of the positioning plate. A reset spring is provided between the locking block and the positioning plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. When spraying pesticides for agricultural pest and disease control by drawing them with a pressure pump, the mixed liquid is filtered by the filter screen installed inside the receiving sleeve to prevent undissolved particles from entering the pressure pump and causing blockage. At the same time, as the drive rod rotates synchronously, the cleaning brush cleans the surface of the filter screen to remove impurities, thus preventing the impurities from clogging the surface of the filter screen. Furthermore, when adding medicine and water inside the machine, the mixing rod can be driven by the motor to mix the medicine inside the machine, which facilitates the uniform spraying of the medicine later.

[0015] 2. After the locking block is squeezed, it slides along the guide rod surface inside the positioning plate and stretches the return spring until the locking block locks the handheld nozzle. Then, the return spring pushes the locking block with its own elasticity to lock the handheld nozzle. The support plate set in the middle of the handheld nozzle supports the handheld nozzle, so as to facilitate the placement of the handheld nozzle. Attached Figure Description

The upper end of 6 is connected to the output end of the motor, and the motor is set on the upper inner wall of the body 1. The anti-clogging mechanism is provided with a receiving sleeve 7, and the left side of the receiving sleeve 7 is connected to the bottom of the telescopic corrugated pipe 3. A cleaning brush 10 is fixedly installed on the right inner wall of the receiving sleeve 7. The upper end of the drive rod 8 forms a synchronous rotation structure with the upper end of the mixing rod 6 through a belt and a pulley. A sleeve 9 is fixedly installed at the bottom of the drive rod 8, and a cleaning brush 10 is nested inside the sleeve 9. A pressure spring 11 is provided between the cleaning brush 10 and the sleeve 9. The end of the cleaning brush 10 is inclined, and the cleaning brush 10 corresponds to the surface of the filter screen 12.

[0026] When using the agricultural pest and disease control spraying device, add water and pesticide through the feeding port on the right side of the machine body 1. Then, start the motor at the top of the machine body 1. The motor will rotate the mixing rod 6 inside the machine body 1, mixing the pesticide and water. After mixing, the user carries the machine body 1 on their back using the shoulder strap 2. The pressure pump 4 is then activated via a remote control connected to the pressure pump 4.
