Description

Technical Field

[0001] The present invention relates to the technical field of grinding devices, and particularly to a raw material crushing device and method for pesticide production. Background Art

[0002] In the field of pesticide production, raw material crushing is a key process, and the process and equipment performance directly affect product quality and production cost. The traditional single crushing method has significant limitations: Although centrifugal crushing equipment can quickly break large raw materials by the centrifugal force generated by high-speed rotation, it is difficult to grind the materials to a fine particle size that meets the pesticide efficacy requirements; Although ball mills are good at fine grinding, when directly processing raw materials with a relatively large initial particle size, due to relying on the repeated impact of steel balls for crushing, the energy utilization rate is extremely low, and only 1%-5% of the energy consumption is used for effective crushing, and the remaining energy is mostly lost in the form of heat energy and sound energy, resulting in a sharp increase in overall energy consumption.

[0003] Even when using a combined process of centrifugal crushing and ball mill refinement, existing equipment mostly consists of independent devices connected in series, which not only occupies a large area and has a high investment cost, but also raw materials are prone to loss and pollution during the transfer process. At the same time, due to the lack of a reasonable classification treatment mechanism, problems such as excessive grinding of fine particles and insufficient crushing of large particles often occur, further exacerbating the energy consumption waste of the motor and the low production efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a raw material crushing device and method for pesticide production, which solves the problem of low energy utilization rate caused by directly ball-milling raw materials.

And when the outer cylinder swings to be axially parallel to the workbench surface, the inner cylinder rotates inside the outer cylinder), so that the grinding media grind the raw materials.

[0009] Preferably, a first end cover and a second end cover are respectively connected to two ends of the outer cylinder, a locking ring is coaxially and slidably connected to the second end cover, a plurality of L-shaped locking rods are fixedly connected to an end face of the locking ring, the L-shaped locking rods penetrate through the second end cover, an annular locking groove is formed in an outer wall of the inner cylinder, when the outer cylinder swings on the workbench, the L-shaped locking rods can slide to abut against or away from an inner wall of the annular locking groove, and thus the inner cylinder is locked or unlocked to / from the outer cylinder.

[0010] Preferably, a mounting seat is fixedly connected to the workbench, a cam is fixedly connected to an end part of the mounting seat, an annular sliding groove is eccentrically formed in the cam, an L-shaped sliding rod is fixedly connected to the locking ring, and the L-shaped sliding rod slides in the annular sliding groove; The annular sliding groove has a first quadrant point and a second quadrant point, a distance between the first quadrant point and a side wall of the cam is smaller than a distance between the second quadrant point and the side wall of the cam, so when the outer cylinder swings upward on the workbench, the L-shaped sliding rod slides from the first quadrant point to the second quadrant point, so that the L-shaped sliding rod slides in a direction away from the second end cover and pulls the L-shaped locking rod to abut against the annular locking groove, and thus the inner cylinder is locked to the outer cylinder.

[0011] Preferably, two first hydraulic rods are symmetrically hinged to a table top of the workbench, end parts of the two first hydraulic rods are symmetrically hinged to an outer wall of the outer cylinder respectively, and when the first hydraulic rods extend and retract, the outer cylinder can be driven to swing on the workbench.

[0012] Preferably, a motor is connected to the workbench. The output end of the motor is fixedly connected to a driving shaft. The end of the driving shaft is connected to the inner shaft through a universal joint. The end of the inner shaft away from the universal joint is fixedly connected to an outer conical ring. The inner wall of the inner cylinder is fixedly connected to an inner conical ring through an annular grid plate. The end face of the second end cover fits against the side wall of the cam. Thus, when the outer cylinder swings upward on the workbench, the second end cover slides along the side wall of the cam, and the outer shaft can slide on the inner shaft so that the outer conical ring moves away from the inner conical ring. And when the outer cylinder swings to an axial direction parallel to the workbench, the second end cover slides along the side wall of the cam, and the outer shaft can slide on the inner shaft so that the outer conical ring abuts against the inner conical ring.

A second hydraulic rod is fixedly connected to the workbench. The output end of the second hydraulic rod abuts against the motor. When the second hydraulic rod shortens, the axial movement range of the outer cylinder in the state where the conical positioning post is not inserted into the limit seat increases.

[0014] A method for crushing raw materials for pesticide production, using a raw material crushing device for pesticide production, includes the following steps: Open the first end cover or the second end cover, put the raw materials into the inner cylinder, and close the first end cover or the second end cover. Control the first hydraulic rod to extend, so that the outer cylinder swings upward on the workbench. Stop the extension of the first hydraulic rod and maintain the length of the first hydraulic rod, so that the outer cylinder is in an inclined state. Start the motor to drive the inner shaft and the worm to rotate. The worm drives the feeding cylinder to axially slide. The inner shaft drives the material throwing cylinder to rotate. The raw materials slide down into the feeding cylinder and gather inside. The feeding cylinder carries the raw materials up to abut against the lower end face of the material throwing cylinder. At this time, the inner conical surfaces of the feeding cylinder and the material throwing cylinder form a continuous state. The material throwing cylinder drives the feeding cylinder to rotate synchronously, so that the raw materials move to the port of the material throwing cylinder along the continuous inner conical surface and are thrown out to impact against the inner wall of the inner cylinder for centrifugal crushing. The crushed raw materials slide down along the inclined inner cylinder to the feeding cylinder again. The feeding cylinder axially reciprocates to crush the raw materials in a cycle. After maintaining the inclined state of the outer cylinder for a period of time, control the first hydraulic rod to shorten, so that the outer cylinder is in a horizontal state. At this time, the motor drives the inner cylinder to rotate relative to the outer cylinder. The grinding medium in the inner cylinder further grinds the raw materials. After grinding for the required time, open the first end cover or the second end cover to discharge the crushed raw materials.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the centrifugal crushing and ball milling modes are switched by the swing of the outer cylinder. First, the centrifugal force of the material throwing cylinder is used to make the raw materials impact the inner wall of the inner cylinder to complete preliminary crushing, and then fine grinding is carried out with the grinding medium in a horizontal state, realizing classified crushing, avoiding the problems of difficult crushing of coarse particles and over-grinding of fine particles in the traditional process, and effectively reducing the overall energy consumption; at the same time, the integrated structure reduces the floor area of the equipment and the loss of raw material transfer, and improves the crushing efficiency and the stability of product quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Refer to Figures 1-6, this embodiment provides a technical solution: a raw material crushing device for pesticide production, including a workbench 100, an outer cylinder 140 is installed on the workbench 100, an inner cylinder 200 is arranged inside the outer cylinder 140, a mounting column 210 is fixedly connected inside the inner cylinder 200, a feeding cylinder 250 is axially slidably connected to the middle of the mounting column 210, a material throwing cylinder 260 is coaxially rotatably connected to the feeding side of the feeding cylinder 250, conical surfaces are arranged inside both the feeding cylinder 250 and the material throwing cylinder 260, and grinding media are placed inside the inner cylinder 200; the outer cylinder 140 can swing on the workbench 100, and when the outer cylinder 140 swings to be axially inclined to the tabletop of the workbench 100, the inner cylinder 200 is fixed to the outer cylinder 140, the material throwing cylinder 260 rotates inside the inner cylinder 200, and the feeding cylinder 250 axially slides inside the inner cylinder 200, so that the feeding cylinder 250 pushes the raw materials into the material throwing cylinder 260, and the material throwing cylinder 260 applies centrifugal force to the raw materials, so that the raw materials impact on the inner wall of the inner cylinder 200, and, when the outer cylinder 140 swings to be axially parallel to the tabletop of the workbench 100, the inner cylinder 200 rotates inside the outer cylinder 140, so that the grinding media grind the raw materials.

[0020] Add the raw materials into the inner cylinder 200, control the outer cylinder 140 to swing to an inclined state, so that the raw materials can slide down to the surface of the mounting column 210. At this time, the inner cylinder 200 is locked to the outer cylinder 140, the feeding cylinder 250 axially slides in the middle of the mounting column 210, a concave surface is arranged on the end face of the mounting column 210, after the feeding cylinder 250 moves down to the lowest state, the raw materials slide along the concave surface of the mounting column 210 into the conical surface of the feeding cylinder 250. After the feeding cylinder 250 moves up, it can abut against the lower end face of the material throwing cylinder 260. The material throwing cylinder 260 drives the feeding cylinder 250 to rotate synchronously. At this time, the raw materials in the feeding cylinder 250 are subjected to centrifugal force and move up along the conical surface into the material throwing cylinder 260, and continue to be subjected to centrifugal force and move up along the inner conical surface of the material throwing cylinder 260 until they are thrown out at the port of the material throwing cylinder 260 and impact on the inner wall of the inner cylinder 200 and are broken, for centrifugal crushing. The broken raw materials fall again on the mounting column 210 inside the inclined inner cylinder 200. The feeding cylinder 250 continuously moves axially back and forth to push the raw materials into the material throwing cylinder 260 and be thrown out again. After cycling for a set time, control the outer cylinder 140 to swing to a horizontal state. At this time, the inner cylinder 200 is unlocked from the outer cylinder 140, and a conical inclined surface is also arranged at a section of the inner wall of the inner cylinder 200 close to the mounting column 210, so that the raw materials can slide down along the inclined surface into the inner space of the inner cylinder 200 away from the mounting column 210. Grinding media are arranged in the space where the raw materials are located at this time. Then control the inner cylinder 200 to rotate, so that the grinding media perform ball milling on the centrifugally crushed raw materials, further refining the raw materials, reducing the overall energy consumption of the device, and at the same time avoiding the situation of excessive grinding of fine particles or insufficient crushing of large particles.

[0021] The middle part of the mounting column 210 is coaxially and rotatably connected to an outer shaft 220. A worm 230 is coaxially and fixedly connected to the outer shaft 220. A cavity is formed in the mounting column 210. Two worm wheels 240 meshing with the worm 230 are fixedly and rotatably connected in the cavity. Eccentric hinges of the end faces of the two worm wheels 240 are connected with connecting rods 241. The ends of the two connecting rods 241 are jointly hinged to a rotating ring 242. The rotating ring 242 is rotatably connected to the feeding cylinder 250.

[0022] The outer shaft 220 is rotatably connected to the middle part of the mounting column 210 through a bearing, and the outer shaft 220 cannot axially move relative to the mounting column 210. When the outer shaft 220 rotates, it can drive the worm 230 to rotate. The worm 230 drives the worm wheel 240 to rotate. At this time, the worm wheel 240 pushes and pulls the rotating ring 242 through the connecting rod 241, so that the rotating ring 242 drives the feeding cylinder 250 to axially slide back and forth on the mounting column 210. And the feeding cylinder 250 can rotate relative to the rotating ring 242. Thus, after the feeding cylinder 250 abuts against the material throwing cylinder 260, the feeding cylinder 250 can rotate, and it does not affect the transmission of the connecting rod 241.

[0023] A key sliding connection is coaxially arranged between the middle part of the outer shaft 220 and an inner shaft 221. The side wall of the inner shaft 221 is fixedly connected to the material throwing cylinder 260 through a bracket 261.

[0024] The inner shaft 221 axially penetrates the outer shaft 220, and the inner shaft 221 is key sliding connected to the outer shaft 220. The rotation of the inner shaft 221 drives the outer shaft 220 to rotate. The inner shaft 221 is fixedly connected to the material throwing cylinder 260. The rotation of the inner shaft 221 drives the material throwing cylinder 260 to rotate, and at the same time drives the outer shaft 220 to rotate, realizing the centrifugal crushing of the raw materials.

[0025] A retaining ring 270 is arranged at the port of the material throwing cylinder 260. A driving ring 271 is fixedly connected to the retaining ring 270 through a cylindrical rod. The round rod penetrates the side wall of the material throwing cylinder 260. A driving cylinder 280 and a driven cylinder 290 are fixedly connected in the mounting column 210. A trachea is communicated between the driving cylinder 280 and the driven cylinder 290. When the feeding cylinder 250 slides, it can drive the driving cylinder 280 to shorten so that the driven cylinder 290 elongates. Thus, the driven cylinder 290 can push the driving ring 271, so that the retaining ring 270 is far away from the port of the material throwing cylinder 260, so that the raw materials are thrown out.

[0026] When the outer cylinder 140 is in an inclined state, the retaining ring 270 can slide under gravity to a state where it fits against the material throwing cylinder 260. Springs or magnets can also be provided between the retaining ring 270 and the material throwing cylinder 260, so that the retaining ring 270 has a tendency to approach the material throwing cylinder 260. When the feeding cylinder 250 moves axially back and forth, it can push the active cylinder 280 to shorten, so that the gas is transmitted to the passive cylinder 290, causing the passive cylinder 290 to extend. Then the passive cylinder 290 pushes the driving ring 271 to move the retaining ring 270 away from the port of the material throwing cylinder 260. Thus, the raw material at the port of the material throwing cylinder 260 is no longer blocked by the retaining ring 270 and is thrown towards the inner wall of the inner cylinder 200. The retaining ring 270 intermittently moves away from the port of the material throwing cylinder 260, enabling the raw material to accumulate a certain amount before being thrown out, ensuring the centrifugal crushing effect.

[0027] The two ends of the outer cylinder 140 are respectively connected with a first end cover 150 and a second end cover 160. A locking ring 400 is coaxially slidably connected to the second end cover 160. A plurality of L-shaped locking rods 410 are fixedly connected to the end face of the locking ring 400. The L-shaped locking rods 410 penetrate through the second end cover 160. An annular locking groove is formed on the outer wall of the inner cylinder 200. When the outer cylinder 140 swings on the workbench 100, the L-shaped locking rods 410 can slide to abut against or away from the inner wall of the annular locking groove, so that the inner cylinder 200 is locked or unlocked from the outer cylinder 140.

[0028] By disassembling and assembling the first end cover 150 and the second end cover 160, raw materials can be added into the inner cylinder 200. When the outer cylinder 140 swings upward, the locking ring 400 can drive a plurality of L-shaped locking rods 410 to slide towards the direction close to the second end cover 160. At this time, the L-shaped locking rods 410 can abut against the inner wall of the annular locking groove on the outer wall of the inner cylinder 200, so that the inner cylinder 200 is locked and does not rotate relative to the outer cylinder 140, thereby reducing the load when the rotation speed of the material throwing cylinder 260 is subsequently increased.

[0029] A mounting seat 420 is fixedly connected to the workbench 100. A cam 430 is fixedly connected to the end of the mounting seat 420. An annular sliding groove 440 is eccentrically formed on the cam 430. An L-shaped sliding rod 401 is fixedly connected to the locking ring 400. The L-shaped sliding rod 401 slides in the annular sliding groove 440; the annular sliding groove 440 has a first quadrant point P1 and a second quadrant point P2. The distance between the first quadrant point P1 and the side wall of the cam 430 is less than the distance between the second quadrant point P2 and the side wall of the cam 430. Thus, when the outer cylinder 140 swings upward on the workbench 100, the L-shaped sliding rod 401 slides from the first quadrant point P1 to the second quadrant point P2, so that the L-shaped sliding rod 401 slides away from the second end cover 160 and pulls the L-shaped locking rod 410 to abut against the annular locking groove, thereby locking the inner cylinder 200 to the outer cylinder 140.

[0030] When the outer cylinder 140 swings upward, the second end cover 160 can slide along the side wall of the cam 430. At the same time, the L-shaped sliding rod 401 slides from the first quadrant point P1 in the annular chute 440 to the second quadrant point P2. Since the distance between the first quadrant point P1 and the side wall of the cam 430 is less than the distance between the second quadrant point P2 and the side wall of the cam 430, at this time, the L-shaped sliding rod 401 can slide in the direction away from the second end cover 160. Thus, the L-shaped sliding rod 401 pulls the L-shaped locking rod 410 to slide in the direction of the second end cover 160, so that the inner cylinder 200 is locked to the outer cylinder 140.

[0031] Two first hydraulic rods 130 are symmetrically hinged on the tabletop of the workbench 100. The end parts of the two first hydraulic rods 130 are respectively symmetrically hinged on the outer wall of the outer cylinder 140. When the first hydraulic rods 130 expand and contract, they can drive the outer cylinder 140 to swing on the workbench 100.

[0032] When the two first hydraulic rods 130 expand and contract, they can drive the outer cylinder 140 to swing to an inclined or vertical state, so that the device can be switched between the centrifugal crushing state and the ball milling state.

[0033] A motor 120 is connected to the workbench 100. The output end of the motor 120 is fixedly connected with a drive shaft 121. The end of the drive shaft 121 is connected to the inner shaft 221 through a universal joint 222. The end of the inner shaft 221 away from the universal joint 222 is fixedly connected with an outer conical ring 320. The inner wall of the inner cylinder 200 is fixedly connected with an inner conical ring 300 through an annular grid plate 310. The end face of the second end cover 160 is attached to the side wall of the cam 430. Thus, when the outer cylinder 140 swings upward on the workbench 100, the second end cover 160 slides along the side wall of the cam 430, and the outer shaft 220 can slide on the inner shaft 221, so that the outer conical ring 320 moves away from the inner conical ring 300. And when the outer cylinder 140 swings to be axially parallel to the workbench 100, the second end cover 160 slides along the side wall of the cam 430, and the outer shaft 220 can slide on the inner shaft 221, so that the outer conical ring 320 abuts against the inner conical ring 300.

[0034] The rotation speed of the motor 120 is controlled by a speed governor. When the outer cylinder 140 swings to an inclined state, the rotation speed of the motor 120 is increased so that sufficient centrifugal force can be applied to the raw materials. The drive shaft 121 is connected to the inner shaft 221 through a universal joint 222, ensuring that the swing of the outer cylinder 140 is not interfered with and the transmission of the motor 120 is not affected. The position of the universal joint 222 is below the cam 430 in the vertical direction. When the outer cylinder 140 swings upward, the second end cover 160 slides along the side wall of the cam 430. Thus, when the outer cylinder 140 swings upward, the inner shaft 221 can slide relative to the outer shaft 220, causing the inner shaft 221 to drive the outer conical ring 320 away from the inner conical ring 300. At this time, the driving force of the inner shaft 221 will not be transmitted to the inner cylinder 200. After the outer cylinder 140 swings to a horizontal state, the second end cover 160 still fits against the side wall of the cam 430. At this time, the inner shaft 221 slides relative to the outer shaft 220 again, causing the outer conical ring 320 to abut against the inner conical ring 300. At this time, the inner cylinder 200 is unlocked from the outer cylinder 140, so that the rotation of the inner shaft 221 can drive the inner cylinder 200 to rotate synchronously. At this time, the rotation speed of the motor 120 is adjusted to decrease through the speed governor to perform ball milling on the raw materials; The annular grid plate 310 connects and supports the inner conical ring 300. At the same time, the annular grid plate 310 blocks the grinding media, so that the grinding media will not enter the range of the material throwing cylinder 260, while the raw materials after centrifugal crushing can pass through the gaps of the annular grid plate 310, enabling the grinding media to further perform ball milling on the raw materials after centrifugal crushing.

[0035] A limit seat 450 is fixedly connected to the tabletop of the workbench 100, and a conical positioning column 460 is fixedly connected to the side wall of the outer cylinder 140. When the outer cylinder 140 swings to an axial direction parallel to the tabletop of the workbench 100, the conical positioning column 460 is inserted into the limit seat 450, so that the outer cylinder 140 is locked to the workbench 100; A second hydraulic rod 110 is fixedly connected to the workbench 100, and the output end of the second hydraulic rod 110 abuts against the motor 120. When the second hydraulic rod 110 shortens, the axial movement range of the outer cylinder 140 in the state where the conical positioning column 460 is not inserted into the limit seat 450 increases.

[0036] When the outer cylinder 140 swings upward, control the second hydraulic rod 110 to shorten. At this time, the outer cylinder 140 can slide slightly in the direction of the motor 120, so that when the outer cylinder 140 swings upward, the conical positioning post 460 can be pulled out of the limit seat 450 without interference. After the outer cylinder 140 swings upward, control the second hydraulic rod 110 to extend, and lock the position of the motor 120 again. When the outer cylinder 140 swings downward, control the second hydraulic rod 110 to shorten again, so that when the conical positioning post 460 is inserted into the limit seat 450, the outer cylinder 140 can move slightly to ensure that the conical positioning post 460 can be stably inserted into the limit seat 450. Subsequently, control the second hydraulic rod 110 to extend, further driving the outer conical ring 320 to approach the inner conical ring 300, increasing the contact force between the two, ensuring the transmission effect. The contact surface between the outer conical ring 320 and the inner conical ring 300 can also be provided with anti-slip lines to ensure that the two are not easy to slide relative to each other.

[0037] A method for crushing raw materials used in the production of pesticides, using a raw material crushing device for pesticide production, including the following steps: Open the first end cover 150 or the second end cover 160, put the raw materials into the inner cylinder 200, and close the first end cover 150 or the second end cover 160; Control the first hydraulic rod 130 to extend, so that the outer cylinder 140 swings upward on the workbench 100, stop the extension of the first hydraulic rod 130 and maintain the length of the first hydraulic rod 130, so that the outer cylinder 140 is in an inclined state; Start the motor 120 to drive the inner shaft 221 and the worm 230 to rotate. The worm 230 drives the feeding cylinder 250 to slide axially, and the inner shaft 221 drives the material throwing cylinder 260 to rotate. The raw materials slide down into the feeding cylinder 250 and gather inside. The feeding cylinder 250 carries the raw materials up to abut against the lower end surface of the material throwing cylinder 260. At this time, the inner conical surfaces of the feeding cylinder 250 and the material throwing cylinder 260 form a continuous state. The material throwing cylinder 260 drives the feeding cylinder 250 to rotate synchronously, so that the raw materials move on the continuous inner conical surface to the port of the material throwing cylinder 260 and are thrown out to impact the inner wall of the inner cylinder 200 for centrifugal crushing; The crushed raw materials slide down along the inclined inner cylinder 200 to the feeding cylinder 250 again, and the feeding cylinder 250 moves axially back and forth to crush the raw materials in a cycle; After maintaining the inclined state of the outer cylinder 140 for a period of time, control the first hydraulic rod 130 to shorten, so that the outer cylinder 140 is in a horizontal state. At this time, the motor 120 drives the inner cylinder 200 to rotate relative to the outer cylinder 140, and the grinding medium in the inner cylinder 200 further grinds the raw materials. After grinding for the required time, open the first end cover 150 or the second end cover 160 to discharge the crushed raw materials.
