The described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 4 A tungsten concentrate raw material crushing mechanism includes a shell 4, a first clamping plate 6 is fixed to the inner wall of one side of the shell 4 by bolts, a hydraulic cylinder 3 is fixed to the outer wall of one side of the shell 4 by bolts, one end of the telescopic part of the hydraulic cylinder 3 passes through the shell 4 and is fixed to the second clamping plate 7 by bolts, and a blocking component for blocking the raw material is provided at a position below the first clamping plate 6 and the second clamping plate 7 in the shell 4;

[0024] Two crushing rollers 15 are rotatably connected to the inner wall of one side of the shell 4 near the bottom, one end of one crushing roller 15 is connected to the first gear 14 through the shell 4 key, and one end of the other crushing roller 15 is connected to the second gear 17 through the shell 4 key, and the first gear 14 is meshed with the second gear 17. A fixing frame 5 is fixed to the outer wall of one side of the shell 4 near the bottom by bolts, and a motor is fixed in the fixing frame 5 by bolts. The second gear 17 at one end of the motor output shaft is fixed, and the second clamping plate 7 is extended and pushed to move by the hydraulic cylinder 3, so that the second clamping plate 7 and the first clamping plate 6 squeeze and crush the material. The extruded and crushed raw materials will continue to fall to the bottom of the shell 4. At this time, the second gear 17 is driven to rotate by the motor, and the second gear 17 drives the first gear 14 to rotate in the opposite direction by meshing with the first gear 14, so that the two crushing rollers 15 rotate in the opposite direction, so that the two crushing rollers 15 crush the raw materials for the second time, avoid the phenomenon of incomplete crushing of the raw materials, and improve the use effect of the crushing mechanism.

[0025] In the utility model, a feed hopper 2 connected to the inside of the shell 4 is fixed to the top of the shell 4 by bolts, so that the material falls between the first clamping plate 6 and the second clamping plate 7. The material blocking assembly includes two inclined chutes 13, and the two chutes 13 are respectively opened on the inner walls of both sides of the shell 4. A slide plate 10 is slidably connected in the two chutes 13, and the slide plate 10 is located below the first clamping plate 6 and the second clamping plate 7 and contacts the first clamping plate 6 and the second clamping plate 7. The slide plate 10 is in an inclined state, and a baffle plate 9 is welded on the upper surface of the slide plate 10, and the baffle plate 9 contacts the second clamping plate 7, so that the raw material is passed through the first clamping plate 6 and the second clamping plate 7. The raw materials are added into the housing 4 through the feed hopper 2. At this time, the raw materials will fall onto the slide plate 10 and be located between the first clamping plate 6 and the second clamping plate 7, thereby temporarily blocking the raw materials. Then, the raw materials are crushed by the first clamping plate 6 and the second clamping plate 7. After the crushing, the hydraulic cylinder 3 contracts and drives the second clamping plate 7 to move away from the first clamping plate 6. When the second clamping plate 7 moves to contact with the baffle plate 9, the second clamping plate 7 drives the slide plate 10 to move along the chute 13 through the baffle plate 9, so that the slide plate 10 no longer blocks the crushed raw materials, so that the crushed raw materials fall downward;

[0026] Two springs 12 are welded on one side of the slide plate 10, and the springs 12 are fixed to the shell 4. Two guide rods 11 are fixed in the shell 4 by bolts. The two guide rods 11 pass through the two springs 12 and the slide plate 10 respectively. When the slide plate 10 moves, the slide plate 10 will squeeze the springs 12. When the slide plate 10 needs to be reset, since the slide plate 10 is in an inclined state, the slide plate 10 will be reset and moved under the action of gravity. At the same time, the squeezed springs 12 will also assist the slide plate 10 in resetting, so that the slide plate 10 can be quickly reset. The first clamping plate 6 and the second clamping plate 7 are in a parallel state. The bottom of the shell 4 is located directly below the crushing roller 15 and is welded with a feed pipe 8 connected to the inside of the shell 4. The outer wall of one side of the shell 4 is fixed with a support frame 1 by bolts.

[0027] Working principle: when it is needed, the raw material is added into the shell body 4 through the feed funnel 2. At this time, the raw material will fall onto the slide plate 10 and be located between the first clamping plate 6 and the second clamping plate 7. Then, the hydraulic cylinder 3 is extended to push the second clamping plate 7 to move, so that the second clamping plate 7 and the first clamping plate 6 squeeze and crush the material. After squeezing and crushing, the hydraulic cylinder 3 contracts to drive the second clamping plate 7 to move away from the first clamping plate 6. When the second clamping plate 7 moves to contact with the baffle plate 9, the second clamping plate 7 will drive the slide plate 10 to move along the chute 13 through the baffle plate 9, so that the slide plate 10 no longer blocks the crushed raw material. At this time, the raw material will continue to fall to the bottom of the shell body 4. At this time, the second gear 17 is driven to rotate by the motor, and the second gear 17 drives the first gear 14 to rotate in the opposite direction by meshing with the first gear 14, so that the two crushing rollers 15 rotate in the opposite direction, so that the two crushing rollers 15 crush the raw material for the second time, avoid the phenomenon of incomplete crushing of the raw material, and improve the use effect of the crushing mechanism.

For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements or components. Those skilled in the art can understand the specific meanings of the above terms in this application according to specific circumstances.
