[0022] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] Spirotetramat is a tetronic acid compound that can be transmitted bidirectionally in crops and can effectively prevent various piercing-sucking mouthparts pests, such as aphids, thrips, psyllids, mealybugs, whiteflies and scale insects.

[0024] Spirotetramat nanosuspension is an agricultural preparation. During its production and processing, large particles in the suspension need to be fixed and ground into nanometers to make it more effective. However, existing sand mills have the disadvantages of insufficient and uneven grinding when used.

[0025] In view of this, the present application embodiment proposes a sand milling device for preparing agricultural nano suspension. Figure 1 to Figure 2 This is a schematic diagram of the structure of a sand mill for preparing agricultural nano suspensions according to the present application.

[0026] See also Figure 1The present application proposes a sanding device for preparing agricultural nano-suspension, the sanding device 100 for preparing agricultural nano-suspension includes a mounting portion 1, at least two sanding portions 2 and a driving portion 3, each sanding portion 2 includes a sanding box 22, a transmission shaft 21 and a plurality of dispersion discs 23, the transmission shaft 21 is arranged inside the sanding box 22, the plurality of dispersion discs 23 are arranged on the transmission shaft 21 and are arranged at intervals along the length direction of the transmission shaft 21, the sanding boxes 22 of the plurality of sanding portions 2 are arranged at intervals on the mounting portion 1 along the vertical direction, two adjacent sanding boxes 22 are connected to each other, the driving portion 3 is arranged on the mounting portion 1 and is transmission-connected to the transmission shaft 21, and the driving portion 3 is used to drive the transmission shaft 21 to rotate.

[0027] In the embodiment provided by the present application, the top of the sanding box 22 located at the top has a feeding port 221, and the bottom of the lowest sanding box 22 has a discharge port 222. Each sanding box 22 has a grinding medium to facilitate the grinding of the material. The sanding parts 2 can be two, three or four, and each sanding part 2 can extend in the horizontal direction, and multiple sanding parts 2 are arranged in sequence from top to bottom. The number of driving parts 3 can be one, and one driving part 3 can drive one transmission shaft 21 to rotate and drive other transmission shafts 21 to rotate. The number of driving parts 3 can also be the same as the number of transmission shafts 21 of the sanding part 2, and drive each transmission shaft 21 to rotate one by one. From top to bottom, the rotation direction of each transmission shaft 21 can be forward, reverse, forward, etc., that is, the rotation direction of the transmission shaft 21 of two adjacent sanding parts 2 is opposite, so that the movement direction of the material in the two adjacent sanding boxes 22 can be opposite. Two adjacent sand mill boxes 22 can be connected through a conveying pipe 6, and the diameter of the conveying pipe 6 is gradually increased from top to bottom, which is beneficial to the dispersion of the ground materials during the falling process.

[0028] When the material needs to be ground, the material is fed into the uppermost sand mill box 22 through the feeding port 221. The driving unit 3 drives the transmission shaft 21 in the sand mill box 22 to rotate, and drives the dispersion plate 23 to rotate. The dispersion plate 23 drives the grinding medium to perform preliminary grinding on the material. The material is gradually ground in the process of moving to the connecting point of two adjacent sand mill boxes 22. The material will fall from the connecting point of two adjacent sand mill boxes 22 into the lower sand mill box 22 under the action of its own gravity. Since the material will become multiple smaller powder objects after grinding, the powder objects are very light. The material will gradually disperse to the surroundings and fall into the next sand mill box 22 during the falling process. The material will be further finely ground in the process of moving in the opposite direction to the second connecting point, and fall into the third sand mill box 22 through the second connecting point for grinding. The material falls into a plurality of sand mill boxes 22 in sequence and is ground, which can increase the number of times the material is ground, increase the contact frequency between the material and the grinding medium, and gradually improve the fineness of the material. This gradual refinement helps the material to obtain a more uniform particle size distribution, thereby making the material ground more fully and evenly. A plurality of sand mill sections 2 are arranged on the mounting section 1 in the vertical direction, which can reduce the floor space of the sand mill device 100 for preparing agricultural nano suspensions. The material falls into a plurality of sand mill boxes 22 in sequence from top to bottom by its own gravity, which can reduce the power consumption of the material during the transportation process between the sand mill boxes 22.

[0029] In some embodiments of the present application, three sanding parts 2 are provided, and the sanding device 100 for preparing agricultural nano suspensions also includes a transmission structure 4, and the transmission structure 4 includes three gears 41, one gear 41 is correspondingly provided with a transmission shaft 21, and two adjacent gears 41 are meshed, and the driving part 3 is connected to a transmission shaft 21 by transmission. By providing three sanding parts 2, the number of sanding parts 2 can be controlled while making the material grind more fully and evenly, saving costs. By providing three gears 41, when one driving part 3 drives one of the transmission shafts 21 to rotate, the remaining two transmission shafts 21 can be driven to rotate, and there is no need to provide three driving parts 3 to drive the three transmission shafts 21 to rotate in a one-to-one correspondence, further saving costs, and saving electricity consumption. Among them, the meshing of two adjacent gears 41 makes the rotation directions of the two adjacent transmission shafts 21 opposite, so that the material has opposite movement directions in the two adjacent sanding boxes 22.

[0030] Furthermore, the three transmission shafts 21 include a driving shaft and two driven shafts, the driving shaft is arranged between the two driven shafts, and the driving unit 3 is connected to the driving shaft in a transmission manner. Since the driving shaft is located between the two driven shafts, the gear 41 of the driving shaft is also located between the other two gears 41. When the driving unit 3 drives the driving shaft to rotate, the gear 41 arranged on the driving shaft drives the remaining two gears 41 to rotate synchronously, thereby causing the remaining two transmission shafts 21 to rotate synchronously. In this way, the transmission of the three gears 41 can be made more stable, thereby improving the transmission accuracy and transmission efficiency of the three gears 41.

[0031] In some embodiments of the present application, the mounting portion 1 includes a mounting base 11 and a fixed base 12, a plurality of sanding boxes 22 are arranged on the mounting base 11, the mounting base 11 is arranged on the top of the fixed base 12, the fixed base 12 is provided with a receiving cavity, the driving portion 3 is arranged in the receiving cavity, the transmission structure 4 also includes a driving pulley 42, a driven pulley 44 and a transmission belt 43, the driving portion 3 drives and connects the driving pulley 42, the driven pulley 44 is arranged on the transmission shaft 21, and the transmission belt 43 is installed between the driving pulley 42 and the driven pulley 44. Among them, the mounting base 11 can extend in the vertical direction, and the plurality of sanding boxes 22 are arranged on the mounting base 11 at intervals in the vertical direction. The driving unit 3 drives the active pulley 42 to rotate, and the active pulley 42 drives the driven pulley 44 to rotate through the transmission belt 43, so that the transmission shaft 21 can be rotated. In this way, the driving unit 3 can also drive the transmission shaft 21 to rotate when it is far away from the transmission shaft 21, which is convenient for the installation of the driving unit 3. The driving unit 3 is in the accommodating cavity of the fixed base 12, that is, the driving unit 3 is located below the sand grinding unit 2, which can reduce the horizontal occupied space of the sand grinding device 100 for preparing agricultural nano suspensions and improve the space utilization rate of the sand grinding device 100 for preparing agricultural nano suspensions.

[0032] In some embodiments of the present application, the drive unit 3 includes a variable frequency motor 31. The variable frequency motor 31 can provide a starting speed as low as zero, achieve soft start, reduce starting shock, and have a longer service life. Since the transmission shaft 21 is provided with multiple frequency conversion motors 31 can be optimally matched with the transmission shaft 21, which can effectively reduce energy waste. In addition, the frequency conversion motor 31 runs smoothly and has low noise.

[0033] In order to make each transmission shaft 21 rotate more smoothly, in some embodiments of the present application, the transmission shaft 21 is provided with a lubrication structure, and the lubrication structure includes three bearings 214. Among them, the three bearings 214 can be arranged at intervals along the length direction of the transmission shaft 21. By arranging three bearings 214 and filling lubricating oil in the bearings 214, the transmission shaft 21 can rotate more smoothly. Each transmission shaft 21 can pass through the corresponding sanding box 22 and extend to the inside of the mounting portion 1. The three bearings 214 can be arranged in the part of the transmission shaft 21 located inside the mounting seat. The three bearings 214 can provide more uniform support, reduce the offset and runout of the transmission shaft 21, and thus improve the rotation stability of the transmission shaft 21. The provision of three bearings 214 can also share the axial and radial loads of the transmission shaft 21, reduce the stress of a single bearing 214, and extend the service life of the bearing 214.

[0034] In order to reduce the temperature of the material, in some embodiments of the present application, the outer wall cover of the sand mill box 22 is provided with a cooling cover 5, and the cooling cover 5 and the outer wall of the sand mill box 22 are surrounded to form a cooling chamber 52, and the cooling cover 5 is provided with a water inlet 51 and a water outlet 53 connected to the cooling chamber 52. In this way, cooling water can be introduced from the water inlet 51 of the cooling cover 5, so that the cooling water flows in the cooling chamber 52, and the cooling water can flow from the water inlet 51 to the water outlet 53. When the cooling water is in the cooling chamber 52, it will directly contact the outer wall of the sand mill box 22, and the material inside the sand mill box 22 will contact the inner wall of the sand mill box 22 during the grinding process, wherein the sand mill box 22 can be made of a metal material with good thermal conductivity, and the heat of the material will be transferred to the cooling water through the wall of the sand mill box 22. After the heat exchange, the cooling water will take out the heat of the material after flowing out of the cooling chamber 52, thereby reducing the temperature of the material. The water inlet 51 and the water outlet 53 can be arranged at intervals along the length direction of the transmission shaft 21. The cooling cover 5 can be bolted to the outer wall of the sanding box 22, which is convenient for disassembling the cooling cover 5. A sealing pad can be provided between the bottom of the cooling cover 5 and the outer wall of the sanding box 22 to prevent the cooling water in the cooling cavity 52 from flowing out of the cooling cavity 52 before reaching the water outlet 53.

[0035] In order to further improve the uniformity of material grinding, in some embodiments of the present application, a positioning cylinder 7 is provided between two adjacent dispersion discs 23, and the two ends of the positioning cylinder 7 are respectively connected to the two dispersion discs 23. By providing the positioning cylinder 7, the spacing between each two adjacent dispersion discs 23 can be made the same, and the spacing is the length of the positioning cylinder 7. When the transmission shaft 21 drives a plurality of dispersion discs 23 with the same spacing to rotate, the material can be ground more evenly. When the dispersion discs 23 are installed on the transmission shaft 21, the first dispersion disc 23 can be installed first, and then one end of the positioning cylinder 7 is connected to the first dispersion disc 23, and the second dispersion disc 23 is connected to the other end of the positioning cylinder 7 and installed on the transmission shaft 21, and then the second dispersion disc 23 is connected to the second positioning cylinder 7. In this way, the installation is carried out in sequence, so that the spacing between each two adjacent dispersion discs 23 can be kept equal during the installation process. Of course, the setting of the positioning cylinder 7 can also limit the dispersion disc 23 axially to improve the grinding stability.

[0036] In order to facilitate cleaning the interior of the sanding box 22, in some embodiments of the present application, a cleaning chamber 213 is provided inside the transmission shaft 21, an opening 212 communicating with the cleaning chamber 213 is provided at one end of the transmission shaft 21, and the transmission shaft 21 is provided with a plurality of water spray holes 211 arranged at intervals along its length direction, and the plurality of water spray holes 211 are communicated with the cleaning chamber 213. When the grinding work is completed, a high-pressure water flow can be introduced into the cleaning chamber 213 inside the transmission shaft 21 through the opening 212, and the high-pressure water flow is sprayed into the interior of the sanding box 22 through the water spray holes 211, so that the interior of the sanding box 22 can be cleaned without disassembling the sanding box 22. The transmission shaft 21 can be rotated, and then a high-pressure water flow is introduced into the cleaning chamber 213, and the high-pressure water flow can be sprayed around the interior of the sanding box 22 through a water spray hole 211 as the transmission shaft 21 rotates, which can further improve the cleaning effect.

[0037] In order to prevent some materials from adhering to the inner wall of the sanding box 22, in some embodiments of the present application, the transmission shaft 21 is provided with a plurality of fixed rods 8 arranged at intervals along its length direction, and each fixed rod 8 is provided with a brush 81 at one end away from the transmission shaft 21. When the transmission shaft 21 rotates, the brush 81 on the fixed rod 8 will rotate accordingly and brush off the materials adhering to the inner wall of the sanding box 22, and the brushed-off materials will continue to be ground. In addition, the provision of the brush 81 can also perform preliminary cleaning on the inner wall of the sanding box 22.
