Description

Technical Field

[0001] This application relates to a coal raw material crushing and powdering machine. Background Technology

[0002] A coal raw material crushing and powdering machine is a specialized device for crushing and preparing samples. It is commonly used in industries such as mining, chemical, and metallurgy. It can crush large pieces of coal raw materials into the required particle size and prepare samples that represent the characteristics of the raw materials. The use of crushing and powdering machines can improve the accuracy and efficiency of sample preparation, help users better understand and control the physical and chemical properties of raw materials, and play an important role in scientific research and production processes.

[0003] When crushing coal raw materials, the crusher will generate a lot of dust. The dust will flow out from the feed hopper, affecting the working environment. If the dust is inhaled by the workers, it will also affect their health. Moreover, the crushed coal raw materials are prone to clogging in the discharge hopper when they are discharged, affecting the feeding speed. The discharge hopper needs to be cleared, thereby reducing work efficiency.

[0004] Therefore, it is desirable to provide a coal-based raw material crushing and powdering machine. Utility Model Content

[0005] This embodiment provides a coal raw material crushing and powdering machine that solves the problems of dust generated during coal raw material crushing flowing out of the feed hopper, affecting the working environment, and being inhaled by workers, which can affect their health; and the crushed coal raw material easily clogging the discharge hopper during discharge, affecting the feeding speed, requiring the discharge hopper to be cleared, thereby reducing work efficiency.

[0006] According to one aspect of this application, a coal-based raw material crushing and powdering machine is provided, including a crushing box, with support plates fixed at both ends of the bottom of the crushing box, a feed hopper provided at the top of the crushing box, a discharge hopper fixed at the bottom of the crushing box, and a crushing structure provided inside the crushing box. The coal-based raw material crushing and powdering machine further includes:

[0007] A dustproof structure is symmetrically arranged inside the feed hopper;

[0008] An anti-clogging structure is provided at the top of the discharge hopper.

[0009] Furthermore, the crushing structure includes a motor, a drive gear, a first crushing bevel gear, a second crushing bevel gear, a driven gear, a third crushing bevel gear, and a fourth crushing bevel gear. The motor is fixed to one side of the top of one side wall of the crushing box, and the drive gear is fixed to the output end of the motor.

[0010] Furthermore, the end of the drive gear away from the motor passes through the side wall of the crushing box and is fixed with a crushing bevel gear, and the other end of the crushing bevel gear is rotatably connected to the inner wall of the other side of the crushing box.

[0011] Furthermore, a second crushing bevel gear meshes with one side of the crushing bevel gear, and both ends of the second crushing bevel gear are rotatably connected to the inner walls on both sides of the crushing box.

[0012] Furthermore, the driving gear is engaged with a driven gear at its bottom. One end of the driven gear passes through the side wall of the crushing box and is fixed with a crushing bevel gear three. The driven gear is rotatably connected to the side wall of the crushing box, and the other end of the crushing bevel gear three is rotatably connected to the inner wall of the other side of the crushing box.

[0013] Furthermore, one side of the crushing bevel gear three is meshed with a crushing bevel gear four, and both ends of the crushing bevel gear four are rotatably connected to the inner walls on both sides of the crushing box.

[0014] Furthermore, the dustproof structure includes a dust baffle plate, a rotating shaft, and a supporting spring. The dust baffle plates are symmetrically arranged on both sides inside the feed hopper, the dust baffle plates are inclined, and the bottom ends of the dust baffle plates abut against each other.

[0015] Furthermore, a rotating shaft is fixed to the top two side walls of the dust baffle, and the other end of the rotating shaft is rotatably connected to the inner walls of the two sides of the feed hopper. Supporting springs are fixed to the bottom two sides of the end of the dust baffle away from the rotating shaft, and the other end of the supporting spring is fixed to the inner wall of the crushing box.

[0016] Furthermore, the anti-blocking structure includes an installation plate, a limiting rod, a spring, a T-shaped anti-blocking rod, and a top rod. The installation plate is located at the middle of the top of the discharge hopper. The limiting rod and the spring are fixed at both ends of the bottom of the installation plate. The spring is sleeved on the outside of the limiting rod. The bottom ends of the limiting rod and the spring are fixed to the bottom of the crushing box.

[0017] Furthermore, a T-shaped anti-blocking rod is fixed to the bottom of the mounting plate, the bottom end of the T-shaped anti-blocking rod extends into the discharge hopper, and a top rod is fixed in the middle of the crushing bevel gear corresponding to the mounting plate.

[0018] The advantages of this application are:

[0019] 1. By setting up a dustproof structure inside the feed hopper, the dust baffles in the dustproof structure are symmetrically arranged inside the feed hopper. The top of the dust baffle is rotatably connected to the inner wall of the feed hopper via a rotating shaft. Support springs are fixed on both sides of the bottom of the dust baffle at the end away from the rotating shaft. When coal raw materials are poured into the feed hopper, the coal raw materials squeeze the dust baffles to both sides and compress the support springs. The dust baffles rotate along the rotating shaft, opening the feed hopper. The coal raw materials enter the crushing box through the feed hopper. When the input of coal raw materials stops, the dust baffles rebound under the action of the support springs. The bottom ends of the dust baffles on both sides inside the feed hopper abut against each other, sealing the feed hopper. This prevents the dust raised in the crushing box from flowing out through the feed hopper, avoiding the impact on the working environment and the possibility of workers inhaling it and affecting their health.

[0020] 2. By setting an anti-blocking structure at the top of the discharge hopper, the top rod in the anti-blocking structure is fixed to the third crushing bevel gear. The mounting plate and the T-shaped anti-blocking rod are fixed to the bottom of the crushing box by the limiting rod and the spring. When the top rod is at the bottom of the third crushing bevel gear, it will squeeze the mounting plate and compress the spring and the limiting rod, thereby causing the T-shaped anti-blocking rod to move down. When the top rod is at the top of the crushing bevel gear, it separates from the mounting plate, and the T-shaped anti-blocking rod at the bottom of the mounting plate moves up. When the crushing structure crushes the coal raw material, the T-shaped anti-blocking rod moves up and down with the rotation of the third crushing bevel gear, which can clear the discharge hopper and prevent the crushed coal raw material from clogging the discharge hopper, thus improving the practicality of the crushing powder sampler.

[0041] The dustproof structure 6 includes a dust baffle 601, a rotating shaft 602, and a support spring 603. The dust baffle 601 is symmetrically arranged on both sides of the feed hopper 3. The dust baffle 601 is inclined and the bottom ends of the dust baffle 601 abut against each other.

[0042] The dust baffle 601 has a rotating shaft 602 fixed on both sides of the top end. The other end of the rotating shaft 602 is rotatably connected to the inner walls of both sides of the feed hopper 3. The bottom of the end of the dust baffle 601 away from the rotating shaft 602 has a support spring 603 fixed on both sides. The other end of the support spring 603 is fixed to the inner wall of the crushing box 1.

[0043] The anti-blocking structure 7 includes a mounting plate 701, a limiting rod 702, a spring 703, a T-shaped anti-blocking rod 704, and a top rod 705. The mounting plate 701 is located at the top center of the discharge hopper 4. The limiting rod 702 and the spring 703 are fixed at both ends of the bottom of the mounting plate 701. The spring 703 is sleeved on the outside of the limiting rod 702. The bottom ends of the limiting rod 702 and the spring 703 are fixed to the bottom of the crushing box 1. The limiting rod is telescopic and limits the spring 703 to prevent the spring 703 from being overstretched or compressed.

[0044] A T-shaped anti-blocking rod 704 is fixed to the bottom of the mounting plate 701. The bottom end of the T-shaped anti-blocking rod 704 extends into the discharge hopper 4. A top rod 705 is fixed in the middle of the crushing bevel gear 506 corresponding to the mounting plate 701.

[0045] The working principle and usage method are as follows: All electrical components mentioned in the application are externally connected to a power supply and control device during use. First, coal raw material is poured into the feed hopper 3. The coal raw material squeezes the dust baffle 601 to both sides and compresses the support spring 603. The dust baffle 601 rotates along the rotating shaft 602, opening the feed hopper 3. The coal enters the crushing chamber 1 through the feed hopper 3. When the input of coal raw material stops, the dust baffle 601 rebounds under the action of the support spring 603. The bottom ends of the dust baffles 601 on both sides of the feed hopper 3 abut against each other, closing the feed hopper 3 and preventing dust raised in the crushing chamber 1 from flowing out through the feed hopper 3. Then, the motor 501 drives the drive gear 502 and the first crushing bevel gear 503 to rotate. The second crushing bevel gear 504, which meshes with the first crushing bevel gear 503, rotates accordingly, crushing the coal raw material. The driven gear 505, which meshes with the drive gear 502, rotates accordingly, thereby driving the third crushing bevel gear 506 to rotate, crushing the coal raw material. The crushing bevel gear 4 507, which meshes with bevel gear 3 506, rotates accordingly. The coal raw material crushed by bevel gear 1 503 and bevel gear 2 504 falls onto bevel gear 3 506 and bevel gear 4 507 for further crushing, improving the crushing effect. The coal raw material after two crushing processes is discharged through the discharge hopper 4. A top rod 705 is fixed in the middle of bevel gear 3 506. When the top rod 705 is at the bottom of bevel gear 3 506, it will squeeze the mounting plate 701 and compress the spring 703 and the limiting rod 702, thereby causing the T-shaped anti-blocking rod 704 to move down. When the top rod 705 is at the top of the bevel gear, it separates from the mounting plate 701, and the T-shaped anti-blocking rod 704 at the bottom of the mounting plate 701 moves up. When the coal raw material is crushed by the crushing structure 5, the T-shaped anti-blocking rod 704 moves up and down with the rotation of bevel gear 3 506, which can clear the discharge hopper 4 and prevent the crushed coal raw material from clogging the discharge hopper 4.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
