Description

Technical Field

[0001] The utility model belongs to the field of pesticide processing, in particular to a pesticide powder processing and screening device. Background Art

[0002] Screening of pesticide powders is a very important step in the production process. The main purpose is to ensure the uniformity, quality and particle size of the product are suitable for the target application.

[0003] In the prior art, pesticide powder is generally screened through a single vibrating screen to screen out powder particles of different sizes. However, a large amount of pesticide dust is easily generated during the application and vibration of the pesticide powder. If the raised dust is not dealt with in a timely manner, it is easy to cause the dust to float everywhere and pollute the surrounding environment. In addition, during the screening process, pesticide particles are easy to adhere to the vibrating screen, causing the screen holes to be blocked, requiring frequent manual cleaning, which not only increases a lot of labor costs, but also reduces the screening efficiency of the pesticide powder.

The linkage unit includes a first pulley 14, which is fixedly connected to the outside of the output end of the motor 11. The inside of the screening box 1 and above the limit block 6 is rotatably connected with a reciprocating screw 15, and the outside of the reciprocating screw 15 is fixedly connected with a second pulley 16. The first pulley 14 and the second pulley 16 pass through the interior of the limit block 6 and are connected by a transmission belt 17. The cleaning brush 9 is threadedly connected to the outside of the reciprocating screw 15.

[0021] Through the above technical scheme, the pesticide powder is first put into the interior of the screening box 1 through the feed funnel 2, and then the suction device 5 and the motor 11 are started through the control panel 21. The suction device 5 can inhale a large amount of dust raised by the pesticide powder through the dust suction pipe 4 and the suction hood 3, and then send it back into the interior of the screening box 1 through the feeding port at the bottom of the dust suction pipe 4, avoiding the pollution of the surrounding environment caused by the large amount of dust raised when the pesticide powder is put in. After it is absorbed, it is re-put into the interior of the screening box 1 for screening, which also avoids the waste of powder and reduces the cost. When the pesticide powder falls to the top of the screen frame 7, the output end of the motor 11 can drive the eccentric wheel 12 to rotate, and the eccentric wheel 12 drives the connecting rod 13 to repeatedly push the hammer column 10, thereby driving the hammer column 10 to reciprocate and knock the screen frame 7, thereby driving the screen frame 7 to vibrate, and the pesticide powder can be screened, and small particles and large particles of pesticide powder can be classified, which is convenient for subsequent distinguishing processing and packaging, and when the motor 11 is running while driving the first pulley 14 outside the output end to rotate, and the first pulley 14 then drives the second pulley 16 and the reciprocating screw 15 to rotate through the transmission belt 17, so that the reciprocating screw 15 drives the external cleaning brush 9 to reciprocate under the limit of the limit rod 8 through the threaded connection relationship, thereby clearing the pesticide powder blocked in the screen frame 7, preventing the screen frame 7 from being seriously blocked and affecting the screening efficiency. After the pesticide powder is put into the interior of the screening box 1, the suction force of the suction hood 3 is used to absorb the raised pesticide dust, which can effectively prevent the dust from flying around and causing pollution to the surrounding environment, and the absorbed pesticide dust is re-put into the interior of the screening box 1 for screening through the feeding port at the bottom of the dust suction pipe 4, which also avoids the waste of powder and reduces the cost. Then, in the process of screening the pesticide powder, the reciprocating cleaning brush 9 can be used to clear the pesticide powder blocked in the screen frame 7, which can effectively prevent the screen frame 7 from being seriously blocked and affecting the screening efficiency.

[0022] Specifically, a collecting frame 18 is provided at the bottom of the inner wall of the screening box 1 , and a box door 19 is installed on the outside of the screening box 1 .

[0023] Through the above technical solution, the small-particle pesticide powder that falls after screening can fall into the inside of the collection frame 18 for easy collection by the staff. By opening the box door 19, the staff can distinguish and collect the large-particle pesticide powder and small-particle pesticide powder on the top of the screen frame 7 and inside the collection frame 18, thereby improving practicality.

[0024] Specifically, rollers 20 are symmetrically installed on both sides of the bottom of the screening box 1, a control panel 21 is installed on one side of the outside of the screening box 1, and the suction device 5 and the motor 11 are electrically connected to the control panel 21.

[0025] Through the above technical solution, the provided roller 20 can facilitate the staff to push the device to any working position, thereby improving the flexibility of use. The provided control panel 21 can facilitate the staff to quickly control the suction device 5 and the motor 11.

[0026] When in use, the pesticide powder is first put into the interior of the screening box 1 through the feed funnel 2, and then the suction device 5 and the motor 11 are started through the control panel 21. The suction device 5 can suck in a large amount of dust raised by the pesticide powder through the dust suction pipe 4 and the suction hood 3, and then re-send it into the interior of the screening box 1 through the feeding port at the bottom of the dust suction pipe 4, avoiding the pollution of the surrounding environment caused by a large amount of dust raised when the pesticide powder is put in, and re-sending it into the interior of the screening box 1 for screening after absorption also avoids the waste of powder and reduces the cost. When the pesticide powder falls to the top of the screen frame 7, the output end of the motor 11 can The eccentric wheel 12 is driven to rotate, and the eccentric wheel 12 drives the connecting rod 13 to repeatedly push the hammer column 10, thereby driving the hammer column 10 to reciprocately knock the screen frame 7, thereby driving the screen frame 7 to vibrate, and the pesticide powder can be screened, and the small particles and large particles of the pesticide powder can be classified, which is convenient for subsequent distinguishing processing and packaging. While the motor 11 is running, the first pulley 14 outside the output end can be driven to rotate, and the first pulley 14 then drives the second pulley 16 and the reciprocating screw 15 to rotate through the transmission belt 17, so that the reciprocating screw 15 drives the external cleaning brush 9 through the threaded connection relationship. The limiting rod 8 makes a reciprocating motion under the limit of the limiting rod 8, thereby clearing the pesticide powder blocked in the screen frame 7, preventing the screen frame 7 from being seriously blocked and affecting the screening efficiency. After the pesticide powder is put into the interior of the screening box 1, the device can absorb the raised pesticide dust through the suction force of the suction hood 3, which can effectively prevent the dust from flying around and causing pollution to the surrounding environment, and the absorbed pesticide dust is re-put into the interior of the screening box 1 for screening through the feeding port at the bottom of the dust suction pipe 4, which also avoids the waste of powder and reduces the cost. Then, in the process of screening the pesticide powder, the screen frame 7 can be cleaned by the reciprocating cleaning brush 9. The blocked pesticide powder inside can be cleared, which can effectively prevent the screen frame 7 from being seriously blocked and affecting the screening efficiency. The small-particle pesticide powder that falls after screening can fall into the inside of the collecting frame 18 for easy collection by the staff. By opening the box door 19, the staff can distinguish and collect the large-particle pesticide powder and the small-particle pesticide powder on the top of the screen frame 7 and inside the collecting frame 18, thereby improving practicality.
