[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 nano suspension 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, when the existing sand mill grinds the suspension, the suspension easily adheres to the inner wall of the grinding cylinder, resulting in waste of the suspension.

[0024] In view of this, the present application embodiment proposes a sand mill for producing agricultural nano suspension. Figure 1 to Figure 2 This is a schematic diagram of the structure of a sand mill for producing agricultural nano suspensions of the present application.

[0025] See also Figure 1 and Figure 2 The present application proposes a sand mill 100 for producing agricultural nano suspensions. The sand mill 100 for producing agricultural nano suspensions includes a mounting base 1, a sand milling structure 2, a hammering structure 3 and a driving structure. The sand milling structure 2 includes a sand milling box 23, a main shaft 21 and a plurality of dispersion discs 22. The sand milling box 23 is arranged on the mounting base 1, the main shaft 21 is arranged inside the sand milling box 23, and the plurality of dispersion discs 22 are arranged on the main shaft 21 and are arranged at intervals along the length direction of the main shaft 21; the hammering structure 3 includes a fixed seat 31, a connecting body 32, a hammering body 34, a first driving member 36, a first transmission member 35 and a second transmission member 33. The fixed seat 31 is arranged on the outer wall of the sand milling box 23, the connecting body 32 is arranged on the fixed seat 31, and the connecting body 32 is arranged on the fixed seat 31. The body 32 is provided with a guide groove 321, the second transmission member 33 is arranged on the beating body 34, and the first driving member 36 is connected to the first transmission member 35 by power so as to drive the first transmission member 35 to rotate; the beating body 34 has a leaving position and a beating position, and the beating body 34 is movably arranged inside the guide groove 321 so that the beating body 34 can switch between the leaving position and the beating position. When the beating body 34 is located at the leaving position, the first transmission member 35 is connected to the second transmission member 33, and the beating body 34 is spaced from the outer wall of the sanding box 23. When the beating body 34 is located at the beating position, the first transmission member 35 is separated from the second transmission member 33, and the beating body 34 abuts against the outer wall of the sanding box 23; the driving structure is arranged on the mounting base 1 and drives the connecting spindle 21.

[0026] In the embodiment provided in the present application, the sand mill box 23 may be provided with a feeding port 231, so that materials and grinding media can be fed into the sand mill box 23 through the feeding port 231. When the material needs to be ground, the driving structure drives the main shaft 21 to rotate, and the main shaft 21 drives the dispersion disk 22 to rotate to grind the material. The first driving member 36 can start to run after the main shaft 21 rotates. Of course, a circuit board assembly can also be provided, and the circuit board assembly electrically connects the first driving member 36 and the driving structure to control the first driving member 36 and the driving structure to run simultaneously. The driving structure may include a driving motor. The sanding box 23 can extend in the horizontal direction. When the first driving member 36 is in operation, it will drive the first transmission member 35 to rotate. During the rotation, the first transmission member 35 will abut against the second transmission member 33 and drive the second transmission member 33 to move upward, that is, drive the second transmission member 33 gradually away from the outer wall of the sanding box 23, and then the second transmission member 33 will drive the hammer body 34 to reach the departure position, that is, the hammer body 34 does not contact the outer wall of the sanding box 23. As the first transmission member 35 continues to rotate, the first transmission member 35 will be separated from the second transmission member 33. In the embodiment of the present invention, the total gravity of the second transmission member 33 and the body 34 of beating is greater than the friction resistance between the body 34 and the inner side wall of the guide groove 321 of beating, the body 34 of beating will fall and arrive at the beating position after the first transmission member 35 breaks away from the second transmission member 33, in the beating position, the body 34 of beating will knock the outer wall of the sand mill housing 23, the first driving member 36 drives the first transmission member 35 to rotate continuously, the body 34 of beating can be reciprocated to knock the outer wall of the sand mill housing 23, and then the material adhering to the inner wall of the sand mill housing 23 can be shaken off, and the material shaken off can continue to be ground. It is understandable that the outer wall of the sand mill housing 23 can be provided with two beating structures 3 spaced apart along the length direction of the main shaft 21, a connecting plate is provided between the two beating bodies 34, the connecting plate two ends are respectively fixed to the two hammering bodies, a plurality of hammering piles extending in the vertical direction can be provided at the bottom of the connecting plate, and a plurality of hammering piles can knock the outer wall of the sand mill housing 23 together with the body 34 of beating. In this way, the striking effect on the sanding box 23 can be increased. Of course, three or more striking structures 3 can be provided.

[0027] Further, the first transmission member 35 comprises a sector gear, and the second transmission member 33 comprises a toothed rack, and the sector gear meshes with the toothed rack. The tooth of the sector gear is distributed in a part of its circumference, and when the first driving member 36 drives the sector gear to rotate, the sector gear meshes with the toothed rack on the hammering body 34 to make the hammering body 34 arrive and leave the position, and along with the continued rotation of the sector gear, the tooth of the sector gear breaks away from the toothed rack, and the part without the tooth of the sector gear can't contact the toothed rack again, and hammering body 34 will fall to the hammering position together with the toothed rack.By arranging toothed rack and sector gear, the outer wall of the hammering body 34 can be knocked back and forth on the sanding casing 23, and the space that hammering structure 3 occupies can also be saved, and the structure of hammering is made more compact, and the hammering body 34 can also be made to reciprocate more steadily and smoothly.Wherein, the number of teeth of the sector gear is less than or equal to the number of teeth of the toothed rack, so, the sector gear can be smoothly disengaged from the meshing with the toothed rack in the process of rotation.

[0028] In order to increase the beating force of the outer wall of the sanding box 23 by beating body 34, in some embodiments of the present application, a first elastic member 341 is provided in the guide groove 321, and the two ends of the first elastic member 341 are respectively connected to the groove bottom of the guide groove 321 and the beating body 34. The groove bottom of the guide groove 321 can be located above the beating body 34, by arranging the first elastic member 341, after the first transmission member 35 breaks away from the second transmission member 33, the beating body 34 can fall to the beating position under the joint action of its own gravity, the gravity of the second transmission member 33 and the elastic force of the first elastic member 341, increase the beating force of the outer wall of the sanding box 23, and improve the vibration effect of the sanding box 23. Wherein, the first elastic member 341 can be two or more, to further increase the knocking effect of beating body 34. The first elastic member 341 is detachably connected to the groove bottom of the guide groove 321, so as to be convenient to replace the first elastic member 341 with greater elasticity. The first elastic member 341 comprises a coil spring.

[0029] In some embodiments of the present application, the beating body 34 is provided with a roller 342, and the roller 342 is between the inner side wall of the guide groove 321 and the beating body 34. The roller 342 can be installed on the beating body 34, and when the part of the beating body 34 reciprocates in the guide groove 321, the setting of the roller 342 can convert the sliding friction between the beating body 34 and the inner side wall of the guide groove 321 into rolling friction, reduce the friction force between the beating body 34 and the inner side wall of the guide groove 321, make the beating body 34 reciprocate more quickly and smoothly, and can improve the beating frequency of the beating body 34 to the outer wall of the sanding box 23. Two rollers 342 can be provided, and the two rollers 342 are respectively installed on the two sides of the beating body 34.

[0030] In order to make the material ground more fully and evenly, in some embodiments of the present application, the sand mill for producing agricultural nano suspension includes at least two sand mill structures 2, and the sand mill boxes 23 of the multiple sand mill structures 2 are arranged at intervals on the mounting base 1 in the vertical direction, and the two adjacent sand mill boxes 23 are connected to each other. The top of the sand mill box 23 located at the top can be provided with a feeding port 231, and the bottom of the bottom sand mill box 23 is provided with a discharge port 232. The sand mill structures 2 can be two, three or four, and the multiple sand mill structures 2 are arranged in sequence from top to bottom. The number of driving structures can be one, and one driving structure can drive one main shaft 21 to rotate and drive other main shafts 21 to rotate. The number of driving structures can also be the same as the number of main shafts 21 of the sand mill structure 2, and drive each transmission shaft to rotate one by one. From top to bottom, the rotation direction of each main shaft 21 can be forward, reverse, forward, etc., that is, the rotation direction of the main shafts 21 of the two adjacent sand mill structures 2 is opposite, so that the moving direction of the material in the two adjacent sand mill boxes 23 can be opposite. Two adjacent sand mill boxes 23 can be connected through a connecting pipe. When the material needs to be ground, the material is put into the uppermost sand mill box through the feeding port 231, and the driving structure drives the main shaft 21 in the sand mill box 23 to rotate, and drives the dispersion plate 22 to rotate, and the dispersion plate 22 drives the grinding medium to perform preliminary grinding on the material. The material is gradually ground in the process of moving to the connection point of the two adjacent sand mill boxes. The material will fall from the connection point of the two adjacent sand mill boxes into the lower sand mill box 23 under the action of its own gravity. Since the material will become a plurality of smaller powder particles after grinding, the powder particles are very light. The material will gradually disperse to the surroundings and fall into the next sand mill box in the process of falling. The material will be further finely ground in the process of moving to the second connection point in the opposite direction, and fall into the third sand mill box 23 through the second connection point for grinding. The material falls into the multiple sand mill boxes 23 in sequence and is ground, which can increase the number of times the material is ground, increase the frequency of contact 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. It is understandable that the hammering structure can be set on the top of the sand mill box 23 located at the top.

[0031] In order to improve the knocking efficiency of the sanding box 23, in some embodiments of the present application, a bidirectional hammering mechanism 5 is provided between two adjacent sanding boxes 23, and the bidirectional hammering mechanism 5 includes a toggle body 55, a fixed body, a hammering body, a second driving member 54 and a second elastic member 53. The fixed body is provided on one of the sanding boxes 23, and the hammering body is rotatably mounted on the fixed body. The hammering body has a first hammering section 52 and a second hammering section 51 that are opposite to each other. The second driving member 54 is connected to the toggle body 55 by power and can drive the toggle body 55 to rotate, so as to When the moving body 55 abuts against the first beating segment 52, the first beating segment 52 and the second beating segment 51 can be synchronously moved away from two adjacent sanding boxes 23. The second elastic member 53 is arranged between the first beating segment 52 and the sanding box 23. The two ends of the second elastic member 53 are respectively connected to the first beating segment 52 and the sanding box 23, and the weight of the first beating segment 52 is greater than the weight of the second beating segment 51, so that the first beating segment 52 and the second beating segment 51 can be synchronously beaten with the two adjacent sanding boxes 23 after the moving body 55 is separated from the first beating segment 52. The second driving member 54 can be a motor. After the grinding work begins, the second driving member 54 can drive the body 55 to rotate, and the body 55 rotation process can be lifted by the first hammering section 52, and the first hammering section 52 is lifted away from the sanding casing 23 below, and the second hammering section 51 can descend and away from the sanding casing 23 above, and in the process that the first hammering section 52 is lifted, the second elastic member 53 is stretched gradually, and the second elastic member 53 can be a spiral spring. Along with the continued rotation of the body 55, the body 55 can be separated from the first hammering section, and the body 55 is not contacted with the first hammering section 52, at this moment, the first hammering section 52 can rely on the weight difference of the self and the second hammering section 51 and the elastic force of the second elastic member 53 to move downwards to hammer the outer wall of the sanding casing 23 below, and the second hammering section 51 will move upwards to hammer the outer wall of the sanding casing 23 above, so, two sanding casings 23 can be knocked at once, and knocking efficiency has been improved. During the continuous rotation of the second driving member 54 , the first beating section 52 and the second beating section 51 will reciprocately beat the two adjacent sanding boxes 23 , further preventing the material from adhering to the inner wall of the sanding box 23 .

[0032] Furthermore, the surfaces of the first beating segment 52 and the tossing body 55 that are close to each other are both arranged in an arc shape. The arrangement of the arc surface can reduce the contact area between the first beating segment 52 and the tossing body 55, reduce the friction resistance between the first beating segment 52 and the tossing body 55, and after the tossing body 55 drives the first beating segment 52 away from the sanding box 23, the tossing body 55 can be more smoothly separated from the first beating segment 52.

[0033] In order to reduce the temperature of the main shaft 21, in some embodiments of the present application, the sand mill for producing agricultural nano suspensions further includes a cooling structure 4, the cooling structure 4 includes a cooling cavity 43, a water inlet pipe 41 and a water outlet pipe 42, the cooling cavity 43 is arranged inside the main shaft 21, the water inlet pipe 41 is rotatably connected to one end of the main shaft 21, the water inlet pipe 41 is communicated with the cooling cavity 43, so as to pass cooling water into the cooling cavity 43, the water outlet pipe 42 is rotatably connected to the other end of the main shaft 21, and the water outlet pipe 42 is communicated with the cooling cavity 43. A transmission structure can be arranged between the drive structure and the main shaft 21, and the main shaft 21 can be rotated by the transmission structure when the drive structure is running. Since the water inlet pipe 41 and the water outlet pipe 42 are respectively rotatably connected to the two ends of the main shaft 21, when the main shaft 21 rotates, the water inlet pipe 41 and the water outlet pipe 42 can remain stationary, and the water outlet pipe 42 and the water inlet pipe 41 can still maintain communication with the cooling cavity 43, and cooling water can be introduced into the cooling cavity 43 of the main shaft 21 through the water inlet pipe 41, and the cooling water will flow from the water inlet pipe 41 to the water outlet pipe 42. During the flow of the cooling water, the heat of the main shaft 21 will be taken out, and the heat of the material in contact with the main shaft 21 will also be taken out, thereby reducing the temperature of the main shaft 21, avoiding the influence of the temperature increase of the main shaft 21 on the performance of the material, and also reducing the temperature of the material in the sanding box 23 in direct contact with the main shaft 21.

[0034] In order to reduce the temperature of the spindle 21 during the grinding process and to facilitate cleaning of the interior of the sand mill box 23 after the grinding process, in some embodiments of the present application, a cleaning pipe 221 is provided between two adjacent dispersion discs 22, and multiple cleaning pipes 221 are sequentially connected along the length direction of the spindle 21. The cleaning pipe 221 is provided with a spray hole 2211, and the cooling cavity 43 is connected to one of the cleaning pipes 221; the spindle 21 is provided with a two-position two-way valve 211 to connect the water inlet pipe 41 with one of the water outlet pipe 42 and the cleaning pipe 221. When grinding the material, the two-position two-way valve 211 can be controlled to connect the water inlet pipe 41 only with the water outlet pipe 42, so that cooling water can be introduced into the cooling cavity 43, and the cooling water will not flow into the cleaning pipe 221, but only flow in the direction of the water outlet pipe 42 to remove the heat of the spindle 21. After the grinding work is completed, the two-position two-way valve 211 is controlled so that the water inlet pipe 41 is connected only to the cleaning pipe 221, wherein a cavity connected to both the cleaning pipe 221 and the water inlet pipe 41 can be provided in the dispersion disk 22, so that the cooling water in the water inlet pipe 41 can enter the cleaning pipe 221 through the cavity of the dispersion disk 22, and the cooling water can be a high-pressure water flow. During cleaning, the main shaft 21 can rotate, and the high-pressure water flow is sprayed to the surroundings of the inside of the sand mill box 23 through the injection hole 2211 to clean the inner wall of the sand mill box 23.

[0035] In order to recycle the cooling water after heat exchange in the cooling cavity 43, in some embodiments of the present application, the cooling structure 4 further includes a heat exchanger 421 and a one-way valve 6. The two ends of the heat exchanger 421 are respectively connected to the water inlet pipe 41 and the end of the water outlet pipe 42 away from the main shaft 21, and the one-way valve 6 is arranged between the heat exchanger 421 and the water inlet pipe 41. The temperature of the cooling water in the cooling cavity 43 of the main shaft 21 entering from the water inlet pipe 41 will increase after heat exchange, and the cooling water with a higher temperature will enter the heat exchanger 421 through the water outlet pipe 42, and the heat exchanger 421 will reduce the temperature of the cooling water. The cooling water flowing out of the heat exchanger 421 will flow back to the water inlet pipe 41 and enter the cooling cavity 43 together with other cooling water in the water inlet pipe 41. In this way, the cooling water can be recycled to reduce the temperature of the main shaft 21 and save water. Among them, the one-way valve 6 can prevent the cooling water in the water inlet pipe 41 from directly flowing into the heat exchanger 421 through the one-way valve 6, so that the cooling water first passes through the main shaft 21 before entering the heat exchanger 421. It can be understood that a circulation pump 7 can be set between the heat exchanger 421 and the one-way valve 6 to provide power for the cooling water to flow, so that the cooling water circulates more smoothly. The cooling water can be introduced only once, and the lower temperature cooling water can be circulated multiple times under the joint action of the circulation pump 7 and the heat exchanger 421 to reduce the temperature of the main shaft 21.
