[0002] In modern agricultural production, environmental protection biological pesticides have gradually been taken seriously and promoted due to their advantages of small environmental impact and safety for human health. In order to improve the stability and use efficiency of biological pesticides, a dosage form of suspending agent has been developed. The suspending agent can evenly disperse the water-insoluble active ingredients of pesticides in water to form a stable suspension, which is convenient for spraying and evenly covering crops, thereby improving the drug efficacy. However, the active ingredients of biological pesticides often have high viscosity and density. When preparing the suspending agent, processes such as sand milling are required for refinement and dispersion to ensure the fineness and stability of the particles. As a key device for preparing the suspending agent, the performance of the sand milling device directly affects the quality and stability of the suspending agent. The sand milling device generally includes a grinding chamber, sand milling media (such as zircon beads, glass beads, etc.), a drive system, and a circulation system; during the sand milling process, the active ingredients of pesticides and additives move at high speed with the sand milling media in the grinding chamber, and through the collision and shearing actions between the media, the large-particle active ingredients of pesticides are refined to the micron level or even the nanometer level to form a stable suspension.

[0003] Most of the current sand milling devices for environmental protection biological pesticide suspending agents on the market do not have a vibration damping structure, which causes the sand mill to affect the connection structure and the sand mill itself due to vibration during operation, resulting in safety hazards for the device, reducing the sand milling efficiency and increasing the maintenance cost. At the same time, the noise during the operation of the device is relatively large, which is likely to affect the environment and the staff. Therefore, we have proposed a sand milling device for an environmental protection biological pesticide suspending agent. Content of the Utility Model

The ventilation hole is located on the side of the sealing groove far away from the sealing ring. There is a gap between the piston rod and the side of the sealing groove close to the sealing ring. One end of the number of sound-absorbing balls close to the vibration damping frame abuts against the inner wall of the triangular groove.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 2 to 5 shown, the present invention provides a sanding device for an environmentally friendly biological pesticide suspension agent, including a vibration damping mechanism 1. A main body mechanism 2 is arranged on the vibration damping mechanism 1, and a working mechanism 3 is arranged above the main body mechanism 2. The vibration damping mechanism 1 includes a vibration damping frame 101. An anti-collision pad 102 is fixedly connected to the inner wall of the vibration damping frame 101. Two piston rods 103 are respectively fixedly connected to both sides of the vibration damping frame 101. One end of the piston rod 103 away from the vibration damping frame 101 is fixedly connected to a spring 104. One end of the spring 104 away from the piston rod 103 is fixedly connected to a buffer seat 105. A sealing groove 106 is opened inside the buffer seat 105. A sealing ring 107 is fixedly connected to the inside of the sealing groove 106. An air vent hole 108 is opened on the inner wall of the sealing groove 106. An airbag 109 is fixedly connected to one side of the air vent hole 108 away from the sealing groove 106. A plurality of triangular grooves 110 are evenly opened on the surface of the vibration damping frame 101. A connecting rod 111 is fixedly connected to the inside of the triangular groove 110. A plurality of sound-absorbing balls 112 are rotatably connected to the connecting rod 111.

[0022] The two piston rods 103 are symmetrically distributed with the vibration damping frame 101 as the center. One end of the piston rod 103 away from the vibration damping frame 101 penetrates through the surface of the buffer seat 105 and extends into the inside of the sealing groove 106. The sealing ring 107 abuts against the piston rod 103. The piston rod 103 is elastically connected to the inner wall of the sealing groove 106 through the spring 104. The air vent hole 108 is located on the side of the sealing groove 106 away from the sealing ring 107. There is a gap between the piston rod 103 and the side of the sealing groove 106 close to the sealing ring 107. One end of the plurality of sound-absorbing balls 112 close to the vibration damping frame 101 abuts against the inner wall of the triangular groove 110.

[0023] Adopting the above solution: By setting the anti-collision pad 102, part of the vibration generated by the sand mill 301 can be absorbed, avoiding the noise generated by the collision between the sand mill 301 and the vibration damping frame 101 and the wear of the sand mill 301, and it can also achieve a certain noise reduction effect. Then, the sand mill 301 will transfer the vibration to the vibration damping frame 101. After the vibration damping frame 101 is stressed, the piston rod 103 will move in the direction close to the buffer seat 105. At this time, the piston rod 103 will squeeze the air and the spring 104 inside the sealing groove 106, thereby increasing the air pressure inside the sealing groove 106. The cooperation between the air pressure inside the sealing groove 106 and the anti-collision pad 102 can improve the vibration damping performance of the sand mill 301. And setting the sealing ring 107 can improve the sealing performance of the sealing groove 106. The air inside the sealing groove 106 will squeeze the airbag 109 through the vent hole 108, causing the airbag 109 to deform, playing a buffering role for the change of the air pressure inside the sealing groove 106. At the same time, by the piston rod 103 squeezing the spring 104, it can also play a buffering and supporting role for the piston rod 103 through the elastic force, avoiding the situation that the sudden change of the air pressure inside the sealing groove 106 causes wear to the device structure.

[0024] As Figures 1 to 2 shown, the main body mechanism 2 includes a frame 201. A controller 202 is fixedly connected to the top of the frame 201. A display screen 203 is arranged on the controller 202. A motor 204 is fixedly connected to the top of the frame 201. Two support frames 205 are fixedly connected to the top of the frame 201. A fixed connection is made between the top of the support frame 205 and the buffer seat 105. The vibration damping frame 101 is located between the two support frames 205. A fixed connection is made between the side of the motor 204 away from the vibration damping frame 101 and the controller 202.

[0025] The working mechanism 3 includes a sand mill 301. One end of the sand mill 301 close to the controller 202 is fixedly connected with a feed pipe 302. One end of the feed pipe 302 away from the sand mill 301 is fixedly connected with a feed pump 303. A cooling pipe 304 is arranged on the sand mill 301. One end of the sand mill 301 away from the controller 202 is fixedly connected with a discharge pipe 305. A sand grinding assembly 306 is rotatably connected inside the sand mill 301. The sand mill 301 is located inside the vibration damping frame 101. The inner wall of the anti-collision pad 102 abuts against the sand mill 301. The vibration damping frame 101 is located between the cooling pipe 304 and the discharge pipe 305. The cooling pipe 304 is located on the side of the feed pipe 302 away from the controller 202.

[0026] Adopting the above solution: By setting the feed pump 303, it is convenient to feed the active ingredients and additives of the pesticide, and by setting the cooling pipe 304, it is convenient to cool the sand mill 301 in the working state.

[0027] The working principle and usage process of the present utility model are as follows: First, start the feed pump 303 to move the active ingredients and adjuvants of the pesticide through the feed pipe 302 into the interior of the sand mill 301. At the same time, operate the display screen 203 to make the controller 202 control the motor 204 to start. Thus, through the transmission inside the frame 201, the sand grinding assembly 306 inside the sand mill 301 rotates, causing the grinding medium inside the sand mill 301 to rotate at a high speed and collide and rub with the material, breaking the material to the required fineness, which plays a role in sand grinding on the active ingredients and adjuvants of the pesticide inside the sand mill 301. At the same time, injecting coolant into the cooling pipe 304 can cool the interior of the sand mill 301. All of the above are prior arts;

[0028] When the grinding medium inside the sand mill 301 rotates at a high speed, it will cause the shell of the sand mill 301 to vibrate. The vibration generated by the sand mill 301 will first be absorbed by the anti-collision pad 102, avoiding the occurrence of noise generated by the collision between the sand mill 301 and the vibration damping frame 101 and the wear on the sand mill 301. Then, the sand mill 301 will transfer the vibration to the vibration damping frame 101. After the vibration damping frame 101 is stressed, the piston rod 103 will move in the direction close to the buffer seat 105. At this time, the piston rod 103 will squeeze the air and the spring 104 inside the sealing groove 106, thereby increasing the air pressure inside the sealing groove 106. The air pressure is used to damp the vibration of the piston rod 103. Also, because there is a gap between the piston rod 103 and the side of the sealing groove 106 close to the sealing ring 107, when the vibration damping frame 101 moves in the direction of one of the buffer seats 105 after being stressed, not only will the piston rod 103 in the moving direction squeeze the spring 104 in the moving direction, but also the second piston rod 103 on the vibration damping frame 101 will stretch the spring 104 away from the moving direction, enabling the vibration damping frame 101 to move in the horizontal direction. At the same time, the elastic force of the two springs 104 can also buffer the movement amplitude of the vibration damping frame 101. The setting of the sealing ring 107 can improve the sealing performance of the sealing groove 106, and the air inside the sealing groove 106 will squeeze the airbag 109 through the vent hole 108, causing the airbag 109 to deform, playing a role in buffering the air pressure change inside the sealing groove 106. At the same time, squeezing the spring 104 by the piston rod 103 can also buffer and support the piston rod 103 through the elastic force. When the noise generated inside the sand mill 301 diffuses outward through the anti-collision pad 102 and extends to the vibration damping frame 101, the energy generated by the noise will be transmitted to several sound-absorbing balls 112 through the inner walls of several triangular grooves 110 on the surface of the vibration damping frame 101 and be absorbed by the sound-absorbing balls 112, achieving the effect of secondary noise reduction. At the same time, the movement of the vibration damping frame 101 can also drive several sound-absorbing balls 112 to rotate on the connecting rod 111, enabling the sound-absorbing balls 112 to evenly absorb noise and converting the energy accumulated inside the sound-absorbing balls 112 into the kinetic energy of the sound-absorbing balls 112 and dissipating it.
