Detailed Implementation

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figure 1-8 As shown, the specific implementation adopts the following technical solution:

[0039] This specific embodiment includes a jaw crusher 1, a feeding mechanism 2, and a screening mechanism 3. The feeding mechanism 2 is mounted above the jaw crusher 1, and the screening mechanism 3 is mounted above the feeding mechanism 2. The rear outlet end of the screening mechanism 3 extends behind the feeding mechanism 2 and is mounted above the feed inlet of the jaw crusher 1. A hoisting unit 4 is fixedly mounted on the table of the jaw crusher 1. The inlet end of the hoisting unit 4 is mounted below the discharge outlet of the jaw crusher 1, and the outlet end of the hoisting unit 4 is mounted above the front feed inlet of the screening mechanism 3.

[0040] The feeding mechanism 2 includes a frame 2-1, a feeding mounting frame 2-2, feeding rollers 2-3, and a feeding conveyor belt 2-4. The frame 2-1 is fixedly mounted on the table of the jaw crusher 1. The feeding mounting frame 2-2 is fixedly mounted on the frame 2-1, with its lower end extending to the side of the frame 2-1. Two feeding rollers 2-3 are arranged in a front-to-back configuration and are screwed onto the feeding mounting frame 2-2 via bearings. A power unit for driving the feeding rollers 2-3 is installed on frame 2-2. The feeding conveyor belt 2-4 is wound in a closed loop around the two feeding rollers 2-3. The feeding conveyor belt 2-4 is a rubber belt with embedded steel wire braids. The screening mechanism 3 includes a guide hopper 3-1 and an adjusting hopper 3-2. The guide hopper 3-1 is fixedly installed on the frame 2-1, and the lower side of the guide hopper 3-1 is mounted above the feeding conveyor belt 2-4. The lower end of the inner part is equipped with a guide roller 3-3 via a bearing. There is an overhead section between the guide roller 3-3 and the rear end plate of the guide hopper 3-1. The guide hopper 3-1 is equipped with an adjusting hopper 3-2, and the lower side of the adjusting hopper 3-2 is mounted above the feeding conveyor belt 2-4. The lower end of the inner part of the adjusting hopper 3-2 is equipped with an adjusting roller 3-4 via a bearing. There is an overhead section between the rear end of the adjusting roller 3-4 and the rear end plate of the adjusting hopper 3-2. The guide roller 3-3 and the adjusting roller 3-4 are spiral roller structures with opposite spiral directions. By rotating the guide roller 3-3 and the adjusting roller 3-4, the material is fed backward. The material falls through the gap between the guide roller 3-3 and the adjusting roller 3-4 for screening. The falling material falls onto the feeding conveyor belt 2-4. The unqualified material that is screened out moves backward and falls from the overhead section at the rear of the guide hopper 3-1 into the feed inlet of the jaw crusher 1.

[0041] Two support guide sleeves 5 are fixedly installed on the inner wall of the frame 2-1, and they are arranged parallel to each other. The end of the support guide sleeve 5 facing the adjusting hopper 3-2 is open. Two support guide rods 6 are fixedly installed on the outer wall of the adjusting hopper 3-2, and the two support guide rods 6 are respectively movably inserted into the two support guide sleeves 5. An adjusting hydraulic rod 7 is fixedly installed on the inner wall of the frame 2-1, and the axis of the adjusting hydraulic rod 7 is parallel to the axis of the support guide sleeve 5. The output shaft of the adjusting hydraulic rod 7 is fixedly installed on the adjusting hopper 3-2. By adjusting the hydraulic rod 7, the adjusting hopper 3-2 is pushed to move, thereby the adjusting hopper 3-2 drives the adjusting roller 3-4 to move, thus realizing the adjustment of the guide roller 3-4. -3. Adjust the gap between rollers 3-4 to screen out materials of different particle sizes; a mounting box 8 is fixedly installed on the outer end wall of the guide hopper 3-1. The end shaft of the guide roller 3-3 is movably inserted into the mounting box 8. A drive shaft 12 is screwed into the mounting box 8 via bearings, and the drive shaft 12 is connected to one end of the guide roller 3-3 inserted into the mounting box 8. The drive shaft 12 is movably inserted into the frame 2-1, and a drive motor 13 is fixedly installed on the frame 2-1. The output shaft of the drive motor 13 is connected to the drive shaft 12. The drive motor 13 drives the drive shaft 12 to rotate, thereby driving the guide roller 3-3 to rotate, thus realizing the spiral... The rotating guide roller 3-3 pushes the material falling on it forward; an adjusting box 9 is fixedly installed on the outer end wall of the adjusting hopper 3-2, and the end shaft of the adjusting roller 3-4 is movably inserted into the adjusting box 9. A spline sleeve 10 is screwed through the adjusting box 9 via a bearing, and the spline sleeve 10 and the end shaft of the adjusting roller 3-4 inserted into the adjusting box 9 are connected by a bevel gear set. The rotation of the spline sleeve 10 drives the adjusting roller 3-4 to rotate, thereby pushing the material falling on it forward through the spiral adjusting roller 3-4. A spline shaft 11 is movably inserted into the spline sleeve 10. One end of the spline shaft 11 is screwed onto the frame 2-1 via a bearing, and the other end of the spline shaft 11 is screwed into the machine via a bearing. Inside the mounting box 8, the splined shaft 11 and the guide roller 3-3 are connected by a bevel gear set through a transmission. The drive motor 13 drives the guide roller 3-3 to rotate, which in turn drives the splined shaft 11 to rotate through the bevel gear set, thereby driving the splined sleeve 10 to rotate. As the adjusting bucket 3-2 moves, the adjusting bucket 3-2 drives the adjusting box 9 to move, and the adjusting box drives the splined sleeve 10 to slide on the splined shaft 11. A guide frame 14 is installed below the outlet end of the elevator unit 4, and the lower end of the guide frame 14 is clamped between the guide bucket 3-1 and the adjusting bucket 3-2. Four end feet are fixedly installed on the guide frame 14, and the end feet of the guide frame 14 are fixedly installed on the frame 2-1.

[0042] When using this device, the mined ore is fed into the jaw crusher 1 for crushing. The jaw crusher 1 uses its reciprocating teeth to squeeze and crush the ore. The crushed material falls from the discharge port of the jaw crusher 1 into the feed port of the elevator unit 4. The elevator unit 4 lifts the crushed material, which is then discharged from the discharge port of the elevator unit 4 and falls into the guide frame 14. The crushed material then falls through the guide frame 14 into the front part of the guide hopper 3-1 and the regulating hopper 3-2, where it is further crushed. The material falls onto the guide roller 3-3 and the adjusting roller 3-4. The drive motor 13 drives the drive shaft 12 to rotate, which in turn drives the guide roller 3-3. The guide roller 3-3, through a bevel gear set, drives the spline shaft 11 to rotate, which in turn drives the spline sleeve 10 to rotate. The spline sleeve 10, through the bevel gear set, drives the adjusting roller 3-4 to rotate. Thus, the adjusting roller 3-4 rotates in the opposite direction to the guide roller 3-3. The guide roller 3-3 and the adjusting roller 3-4 push the crushed material on them towards the feed end of the jaw crusher 1. During this process, the material meets the particle size distribution requirements. Crushed material of the specified diameter falls from the gap between the guide roller 3-3 and the adjusting roller 3-4 onto the feeding conveyor belt 2-4. Unqualified crushed material is pushed and falls back into the jaw crusher 1 for secondary crushing. The rotating feeding roller 2-3 drives the feeding conveyor belt 2-4 to move, sending out the crushed material that meets the specified diameter. This process achieves the crushing and screening of bentonite ore, ensuring that the mined ore is completely crushed to the qualified particle size and discharged. Adjusting the hydraulic rod 7 pulls the adjusting bucket 3-2, which in turn drives the adjusting roller. The movement of rollers 3-4 adjusts the gap width between the adjusting roller 3-4 and the guide roller 3-3, thereby adjusting the screening of crushed materials of different particle sizes. When the gap between the guide roller 3-3 and the adjusting roller 3-4 increases, larger particle sizes of crushed materials can be screened out. Conversely, when the gap between the guide roller 3-3 and the adjusting roller 3-4 decreases, only smaller particle sizes of materials can be screened out. When the adjusting hopper 3-2 moves, it drives the adjusting box 9 to move. The adjusting box 9 slides on the spline shaft 11 through the spline sleeve 10, and the adjusting hopper 3-2 drives the support guide rod 6 to slide inside the support guide sleeve 5.

[0043] Compared with the prior art, the beneficial effects of the present invention are:

[0044] 1. This device integrates a jaw crusher 1 and a screening mechanism 3, thereby realizing the mining, crushing, and screening of bentonite ore, thus achieving integrated mining and processing of ore and improving mining efficiency.

[0045] 2. This device is equipped with guide rollers 3-3 and adjusting rollers 3-4 with opposite rotation and spiral directions, so as to feed and screen the crushed material, screen out the material smaller than the set particle size, and send the unqualified crushed material back to the jaw crusher 1 for secondary crushing.

[0046] 3. This device sets up an adjustable regulating hopper 3-2 and installs an adjusting roller 3-4 on the regulating hopper 3-2. By adjusting the position of the regulating hopper 3-2, the gap width between the guide hopper 3-1 and the regulating hopper 3-2 can be adjusted, thereby achieving the screening of crushed materials of different particle sizes.
