Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medicinal material processing equipment, in particular to an ultra-fine pulverizer. Background Art
[0002] When processing medicinal materials, they need to go through the processes of picking, cleaning, cutting, crushing, grinding, packaging, etc. Among them, the crushing step is to break the medicinal materials in pieces or blocks into fine particles for sale or other processing. When crushing medicinal materials, an ultra-fine grinder is required;
[0003] The scope of medicinal material ultrafine pulverizer is relatively large. Any pulverizer that can pulverize medicinal materials into fine particles can be called an ultrafine pulverizer. Its main principle is to use the high-speed relative motion of pulverizing mechanisms such as pulverizing knives, impact hammers, and weight balls to pulverize the pulverized materials through comprehensive effects such as impact, cutting, friction, and impact between materials.
[0004] However, there are still some defects in the pulverizer that uses a pulverizer to cut and crush medicinal materials at high speed, such as:
[0005] The outer shell of the grinder is usually fixed. When the crushing blades rotate at high speed inside the shell to cut, they can usually only cut a part of the medicinal materials. The medicinal materials in the gap between the two crushing blades cannot be crushed quickly, which will affect the cutting efficiency. In addition, when the outer shell remains fixed, the screen cannot be shaken, and the fine particles on the screen are accumulated for a long time, and the holes of the screen may be blocked. Summary of the invention
[0006] The utility model provides an ultrafine pulverizer to solve the problems raised in the above background technology.
[0007] The technical solution of the utility model is achieved in this way:
[0008] An ultrafine pulverizer comprises a base, a shell and a central shaft;
[0009] Base: A power source is fixed at one end of the base;
[0010] Central shaft: The central shaft rotates in the base and one end of the central shaft is fixed to the output end of the power source, and the power source drives the central shaft to rotate;
[0011] Shell: The upper end of the shell is provided with a feed port and the lower end side wall is penetrated by a screen, the shell is movably sleeved outside the central shaft, the central shaft is located at one end of the shell and has a circular array and a linear array of crushing knives, and the end of the central shaft is installed with a power transmission component to drive the shell to move back and forth laterally;
[0012] By adopting the above technical solution, the power source drives the central shaft to rotate, and the central shaft drives the crushing knife to rotate. The crushing knife rotates at high speed to cut the medicinal materials in the shell at high speed, so as to achieve the purpose of crushing the medicinal materials. The fine-grained medicinal materials are discharged after being screened by the screen to obtain medicinal material particles that meet the specified particle size, and when the central shaft rotates, the power transmission component drives the shell to move back and forth laterally to make the shell shake left and right. On the one hand, the medicinal materials located between the two adjacent crushing knives on the left and right can be moved under the crushing knives for cutting and crushing, thereby improving the crushing efficiency. On the other hand, the medicinal material particles on the screen can be shaken, so that qualified medicinal material particles can be quickly screened out from the screen to avoid the medicinal material particles clogging the screen.
[0013] Preferably, the power source is a motor and the output end of the motor is fixed to one end of the central shaft.
[0014] Preferably, the power transmission assembly includes a first bevel gear, a second bevel gear, a reducer, a turntable, an intermediate rod and a tie rod, the first bevel gear is fixedly sleeved on the end of the central shaft, the first bevel gear is meshed with the second bevel gear, the second bevel gear is fixed to the input end of the reducer, a turntable is fixed to the output end of the reducer, an intermediate rod is eccentrically rotated by a rotating shaft on the side of the turntable, the other end of the intermediate rod is rotated on one end of the tie rod through the rotating shaft, and the other end of the tie rod is laterally movable through the side of the base and then fixed to the side of the shell;
[0015] By adopting the above technical solution, the central shaft drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the input end of the reducer to rotate, the output end of the reducer drives the turntable to rotate, the turntable drives one end of the intermediate rod to rotate eccentrically, so that the other end of the intermediate rod drives the tie rod to move laterally, and the tie rod drives the outer shell to move laterally, so as to convert the rotational power of the central shaft into power to drive the outer shell to move laterally.
[0016] Preferably, the reducer is mainly composed of a first cylindrical gear and a second cylindrical gear, the first cylindrical gear and the second bevel gear coaxially rotate in the base, the first cylindrical gear and the second cylindrical gear are meshed, the number of teeth of the first cylindrical gear is less than the number of teeth of the second cylindrical gear, and the second cylindrical gear and the turntable coaxially rotate in the base;
[0017] By adopting the above technical solution, the number of teeth of the first cylindrical gear is smaller than the number of teeth of the second cylindrical gear, so that the rotation speed of the turntable is slower and the lateral reciprocating speed of the outer shell is slower, that is, while ensuring the high-speed rotation of the central axis, the outer shell is prevented from moving too fast and unstable movement of the outer shell is avoided.
[0018] Preferably, a material storage shell is fixed at the lower end of the outer shell, the material storage shell is located directly below the screen, and a discharge port is provided at the center of the lower end of the material storage shell;
[0019] By adopting the above technical solution, the material storage shell can temporarily store fine-grained medicinal materials, and the medicinal materials can be discharged after all the medicinal materials are crushed.
[0020] Preferably, the inner bottom side of the material storage shell is concave from both ends to the middle, and the material outlet of the material storage shell is arranged at the concave part of the inner bottom side;
[0021] By adopting the above technical solution, when the discharge port of the material storage shell is opened, the fine-grained medicinal materials can slide quickly toward the discharge port, thereby preventing the medicinal materials from accumulating in the material storage shell.
[0022] By adopting the above technical solution, the beneficial effects of the utility model are as follows:
[0023] The utility model drives the central shaft to rotate through a power source, and the central shaft drives the crushing knife to rotate. The crushing knife rotates at high speed to cut the medicinal materials in the shell at high speed, so as to achieve the purpose of crushing the medicinal materials. The fine-grained medicinal materials are discharged after being screened by the screen to obtain medicinal material particles that meet the specified particle size. When the central shaft rotates, the power transmission component drives the shell to move back and forth horizontally to make the shell shake left and right. On the one hand, the medicinal materials located between the two adjacent crushing knives on the left and right can be moved under the crushing knives for cutting and crushing, thereby improving the crushing efficiency. On the other hand, the medicinal material particles on the screen can be shaken, so that qualified medicinal material particles are quickly screened out from the screen, thereby avoiding the medicinal material particles from clogging the screen.
