[0002] Pesticides are an indispensable and important material in modern agricultural production. Their production quality and efficiency are directly related to the effect of agricultural production and farmers' income. In the production process of pesticides, the grinding and filling of powder are crucial links. The performance and efficiency of the grinding device not only affect the fineness and uniformity of the pesticide, but also directly affect the efficacy and use effect of the pesticide. The filling link follows the grinding, which is to quantitatively and accurately fill the finely ground powder or liquid into the packaging container.

These block particles need to be crushed into suitable particle sizes before they can be ground into powder by the grinding device (if the particles are large, the particles cannot enter the gap at the bottom of the grinding disk for grinding). In other words, crushing processing is required before grinding. The process is cumbersome and requires circulation between the crushing and grinding stations. The efficiency is low and the practicality is poor. Summary of the invention

Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Please refer to Figures 1 to 14 As shown:

[0041] Embodiment 1: The present invention provides a preliminary grinding device for pesticide canned powder, comprising an external component 1 and an internal component, wherein the external component 1 comprises a mounting shell 101, a support frame 102, a drive motor 103 and a track rod 104, wherein the support frame 102 is fixedly mounted on the side of the mounting shell 101, the drive motor 103 is fixedly mounted on the bottom of the mounting shell 101, and the track rod 104 is fixedly mounted inside the mounting shell 101; the internal component consists of a grinding mechanism 2 and a crushing mechanism 3;

[0044] In the disclosed embodiment, the outside of the rod body of the adjusting rod 302 is provided with a thread, and the adjusting rod 302 is screwed to the inside of the force block 303 through the rod body thread. In use, the adjusting rod 302 can realize the switching between the two processing modes of the internal components and the function of regulating the minimum crushing particle size that the crushing mechanism 3 can achieve. When the adjusting rod 302 is rotated, the adjusting rod 302 can drive the force block 303 to move inside the positioning groove 3013 through the rod body thread, thereby changing the actual use position of the force block 303. By changing the actual use position of the force block 303, the switching between the two processing modes of the internal components and the function of regulating the minimum crushing particle size that the crushing mechanism 3 can achieve.

[0045] In the embodiment of the present disclosure, the interior of the mounting shell 101 is provided with a feed port 1011, a crushing chamber 1012, a grinding chamber 1013 and a discharge port 1014 from top to bottom in sequence, the grinding mechanism 2 is located inside the grinding chamber 1013, and the crushing mechanism 3 is located inside the crushing chamber 1012, the top of the crushing chamber 1012 and the top of the crushing top plate 301 are both conical in design, and the conical angle of the top of the crushing chamber 1012 is greater than the conical angle of the top of the crushing top plate 301. In use, when the force block 303 is located in the positioning groove 3013 and is at the bottom of the positioning groove 3013, the internal components are in a mixed processing mode, and the internal components can have both the function of crushing the pesticide block. The crushing and grinding processing operation of the block-shaped particles of the pesticide is performed. After the block-shaped particles of the pesticide are poured into the interior of the installation shell 101 through the feed port 1011, the internal components can realize the processing operation under the action of the driving motor 103. When the driving motor 103 rotates, it can drive the grinding disc 202 to rotate through the driving shaft 201, so that when the grinding disc 202 rotates, it can crush the particles entering the bottom of the grinding disc 202 through the cooperation with the bottom cavity wall of the grinding chamber 1013. In this process, since the crushing mechanism 3 is located at the top of the grinding mechanism 2, the block-shaped particles of the pesticide will be crushed to a suitable particle size by the crushing mechanism 3 before being ground into powder, and the force block 3 03 is located just above the force block 304, and a force protrusion 3041 is provided inside the force block 304, a "V"-shaped, continuous force groove 2031 is provided outside the rod body of the linkage rod 203, and the force protrusion 3041 is inserted into the force groove 2031, when the grinding disc 202 rotates, it can drive the linkage rod 203 to rotate synchronously, when the linkage rod 203 rotates, the force groove 2031 can drive the force block 304 to reciprocate up and down inside the crushing chamber 1012 through the force protrusion 3041, when the force block 304 reciprocates upward, it can drive the crushing top plate 301 to move upward synchronously by resisting the force block 303, so as to move the grinding disc 202 located at the crushing chamber 1012 to move upward. The pesticide particles on the top of the crushing top plate 301 are squeezed and crushed. A lower limit tension spring 3012 is provided at the bottom of the crushing top plate 301, and the two ends of the lower limit tension spring 3012 are respectively fixedly connected to the bottom of the crushing top plate 301 and the top of the force block 304. When the force block 304 moves downward, under the action of the lower limit tension spring 3012, the crushing top plate 301 will move downward synchronously, so that the crushed pesticide particles that meet the processing particle size will automatically fall into the grinding chamber 1013 for grinding into powder, and the ground pesticide will be discharged through the discharge port 1014 for people to collect and use in subsequent filling processing. It is convenient and flexible to use and has a high degree of functional integration.

[0046] In the embodiment of the present disclosure, a limiting groove 1041 is provided on the outside of the track rod 104, and a limiting block 3011 is provided on the inside of the crushing top plate 301, and the limiting block 3011 is inserted into the inside of the limiting groove 1041. In use, since the distance when the force-applying groove 2031 drives the force-applying block 304 to move up and down through the force-applying protrusion 3041 is fixed, that is, the upper limit position and the lower limit position of the moving position of the force-applying block 304 are fixed, after the use position of the force-bearing block 303 is changed (that is, when the force-bearing block 303 is not at the top of the positioning groove 3013), when the force-applying block 304 moves upward, the force-bearing block 303 is in conflict with the force-bearing block 303. The machine will also change, so that the maximum upward movement distance of the crushing top plate 301 will also change, thereby changing the minimum distance between the crushing top plate 301 and the top cavity wall of the crushing chamber 1012 during crushing, that is, the minimum crushing particle size of the crushing mechanism 3 is adjusted, which can adapt to the crushing of different types of pesticide block particles and grinding into powder processing operations, and with the coordinated use of the limit groove 1041 and the limit block 3011, the lower dead point position of the crushing top plate 301 is always fixed, and the crushing top plate 301 will not move downward excessively, causing the pesticide particles that do not meet the grinding particle size to fall into the grinding chamber 1013, and the processing is stable.

[0047] In the disclosed embodiment, the block cross-section of the force block 303 is a regular polygon, and a positioning groove 3013 is provided inside the crushing top plate 301, and the force block 303 is inserted into the inside of the positioning groove 3013. In use, when the force block 303 is at the top of the positioning groove 3013, the internal components are in the grinding processing mode. Since the force block 303 is at the top of the positioning groove 3013, even if the force block 304 moves to the upper limit position during reciprocating movement, the force block 304 will not contact the force block 303, so that the crushing top plate 301 will not change position at this time, that is, only the grinding mechanism 2 is working at this time. After pouring in pesticide particles that meet the processing grinding particle size, the pesticide particles can directly reach the inside of the grinding chamber 1013 for grinding processing, which is easy to use and fast processing.

[0048] In the disclosed embodiment, a sealing cover 3014 is provided at the bottom of the crushing top plate 301. This design can prevent pesticide particles from falling into the gap between the grinding mechanism 2 and the crushing mechanism 3, thereby ensuring the normal use of the internal components and improving the stability of the device.

[0049] Specific usage and function of this embodiment: In the present invention, according to the actual particle size of the pesticide particles to be processed, a suitable processing mode is selected, and the internal components have two mixing processing modes and a grinding processing mode. The internal components can be switched between the two processing modes and the function of regulating the minimum crushing particle size that the crushing mechanism 3 can achieve through the adjustment rod 302. When the adjustment rod 302 is rotated, the adjustment rod 302 can drive the force block 303 to move inside the positioning groove 3013 through the rod body thread, thereby changing the actual use position of the force block 303. By changing the actual use position of the force block 303, the internal components can be switched between the two processing modes and the function of regulating the minimum crushing particle size that the crushing mechanism 3 can achieve. When the force block 30 When the positioning groove 3013 is at the bottom of the positioning groove 3013, the internal components are in a mixed processing mode. At this time, the internal components can perform both crushing and grinding processing operations on the bulk pesticide particles. After the bulk pesticide particles are poured into the interior of the mounting shell 101 through the feed port 1011, the internal components can realize the processing operation under the action of the driving motor 103. When the driving motor 103 rotates, it can drive the grinding disc 202 to rotate through the driving shaft 201, so that the grinding disc 202 can crush the particles entering the bottom of the grinding disc 202 through the cooperation with the bottom cavity wall of the grinding chamber 1013 when rotating. In this process, since the crushing mechanism 3 is located at the top of the grinding mechanism 2, the bulk pesticide particles are crushed before being ground into powder. The crushing mechanism 3 will first crush the pesticide particles to a suitable particle size. When the grinding disc 202 rotates, it can drive the linkage rod 203 to rotate synchronously. When the linkage rod 203 rotates, the force groove 2031 can drive the force block 304 to move back and forth up and down inside the crushing chamber 1012 through the force protrusion 3041. When the force block 304 moves back and forth upward, it can drive the crushing top plate 301 to move upward synchronously by contacting the force block 303, thereby squeezing and crushing the pesticide particles located on the top of the crushing top plate 301. When the force block 304 moves downward, under the action of the lower limit tension spring 3012, the crushing top plate 301 will move downward synchronously, so that the crushed pesticide particles that meet the processing particle size will automatically fall into the grinding chamber 1013 for grinding. The processing operation of powder is carried out, and the ground pesticide will be discharged through the discharge port 1014 for people to collect and use for subsequent filling processing. Since the distance when the force block 304 is driven to move up and down by the force protrusion 3041 is fixed, that is, the upper limit position and the lower limit position of the moving position of the force block 304 are fixed, after the use position of the force block 303 is changed (that is, when the force block 303 is not at the top of the positioning groove 3013), the timing of the force block 304 contacting the force block 303 when moving upward will also change, so that the maximum upward movement distance of the crushing top plate 301 will also change, thereby changing the minimum distance between the crushing top plate 301 and the top cavity wall of the crushing chamber 1012 during crushing, that is, adjusting the minimum crushing particle size of the crushing mechanism 3.It can adapt to the processing operations of crushing different types of pesticide block particles and grinding them into powder. With the coordinated use of the limit groove 1041 and the limit block 3011, the lower dead point position of the crushing top plate 301 is always fixed, and the crushing top plate 301 will not move down excessively, causing the pesticide particles that do not meet the grinding particle size to fall into the grinding chamber 1013. When the force block 303 is at the top of the positioning groove 3013, the internal components are in the grinding processing mode. Since the force block 303 is at the top of the positioning groove 3013, even if the force block 304 moves to the upper limit position during reciprocating movement, the force block 304 will not contact the force block 303, so that the crushing top plate 301 will not change position at this time, that is, only the grinding mechanism 2 is working at this time. After the pesticide particles that meet the processing grinding particle size are poured in, the pesticide particles can directly reach the inside of the grinding chamber 1013 for grinding processing.
