[0001] This invention relates to the field of crushing equipment technology, and in particular to a crushing device for processing mirabilite ore. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to crushing equipment is also constantly improving. The crusher for processing mirabilite is an auxiliary device used in the production process of mirabilite to crush and screen the mirabilite for pretreatment before subsequent processing.

[0003] Currently, the equipment used for crushing mirabilite ore cannot screen the crushed mirabilite ore while crushing it. It is necessary to screen the crushed mirabilite ore separately after crushing, and then perform secondary crushing on the insufficiently crushed mirabilite ore that was screened out. The operation is cumbersome and inconvenient, and the crushing efficiency of mirabilite ore is low, which is not conducive to the use of crushing equipment. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: current devices for crushing mirabilite ore cannot screen the crushed mirabilite ore while crushing it. After crushing, the crushed mirabilite ore needs to be screened separately, and only then can the insufficiently crushed mirabilite ore be subjected to secondary crushing. This operation is cumbersome and inconvenient, and the crushing efficiency of mirabilite ore is low, which is not conducive to the use of crushing devices. Therefore, this invention proposes a crushing device for processing mirabilite ore.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A crushing device for processing mirabilite ore includes a crushing box, on which a feed pipe, a transparent glass window and two first motors are fixedly installed. Each first motor has a rotating shaft fixedly connected to its drive end, and a crushing roller is fixedly connected to each rotating shaft. Inclined plates are fixedly connected to the inner walls on both sides of the crushing box. An opening is provided on one side of the crushing box, a sieve plate is rotatably connected to the inner wall of one side of the crushing box, a collection frame is provided on the lower inner wall of the crushing box, and a rake assembly is provided on the crushing box. The rake assembly includes a reciprocating screw rotatably mounted on the crushing box, a fixing block is threadedly connected to the reciprocating screw, and a rake bar is fixedly connected to the lower surface of the fixing block. The grinding chamber is provided with a sliding assembly, which includes a slide rod slidably mounted on the grinding chamber. The slide rod has an L-shaped cross-section, and a horizontal plate is fixedly connected to one end of the slide rod. The horizontal plate is located below the two inclined plates.

[0006] Preferably, a limiting groove is provided on one side of the crushing box, a limiting block is slidably installed in the limiting groove, a slot for connecting the slide rod is provided on the limiting block, a first spring is sleeved on the slide rod, one end of the first spring is fixedly connected to the slide rod, and the other end of the first spring is fixedly connected to the surface of the crushing box.

[0007] Preferably, a groove is provided on one side surface of the crushing box, a bracket is slidably installed in the groove, a limiting plate is fixedly connected to the upper surface of the bracket, and the upper surface of the limiting plate is in contact with the lower surface of the sieve plate.

[0008] Preferably, a rectangular groove is formed on one side surface of the crushing box, a rectangular block is slidably connected in the rectangular groove, a slot is formed on one side of the rectangular block, one end of the bracket is engaged with the slot, and a second spring is fixedly connected to the inner wall of one side of the rectangular groove, and the second spring is fixedly connected to the rectangular block.

[0009] Preferably, an ear plate with an L-shaped cross-section is fixedly connected to one side surface of the crushing box, and a second motor is fixedly connected to the ear plate. The drive end of the second motor is fixedly connected to the reciprocating lead screw.

[0010] Preferably, a fixed shaft is rotatably connected to the crushing box, a crossbar and a plurality of striking rods are fixedly connected to the fixed shaft, a torsion spring is sleeved on the fixed shaft, one end of the torsion spring is fixedly connected to the fixed shaft, and the other end of the torsion spring is fixedly connected to the inner wall of the crushing box.

[0011] Preferably, a vertical groove is provided on one side of the crushing box, and a moving plate with a T-shaped cross-section is slidably connected in the vertical groove. A pressing rod is fixedly connected to the lower surface of the moving plate. The lower end of the pressing rod is set as an arc surface, which fits against the upper surface of the horizontal bar.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. Push the sliding rod so that the horizontal plate is directly below the two inclined plates and fits against the lower surface of the two inclined plates. After sealing the gap between the two inclined plates, pull the rectangular block. At the same time, one end of the bracket will disengage from the opening. The bracket and the limiting plate will move vertically downward under the action of gravity. The screen plate will also deflect downward inside the opening under the action of gravity. After the screen plate rotates, it will change from a horizontal state to an inclined state. The larger mirabilite above the screen plate can slide along the screen plate under the action of gravity and be discharged through the opening. The collected larger mirabilite can be directly poured into the feed pipe for secondary crushing. The operation is relatively convenient and quick, and the crushing efficiency of mirabilite is high, which is beneficial to the use of the crushing device. 2. As the rake bar moves back and forth with the fixed block, it can rake and separate the accumulated mirabilite on the screen plate, so that the mirabilite of appropriate size can pass through the screen holes and fall into the collection frame. During the rotation of the cam, the rotating shaft and multiple striking rods can deflect back and forth multiple times. The multiple striking rods can strike the screen plate multiple times, so that the screen plate has a better screening effect on the mirabilite and is beneficial to the use of the crushing device.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Reference Figures 1-8 A crushing device for processing mirabilite ore includes a crushing box 1. A feed pipe 9, a transparent glass window 2, and two first motors are fixedly installed on the crushing box 1. A rotating shaft 18 is fixedly connected to the drive end of each first motor. A crushing roller 27 is fixedly connected to each rotating shaft 18. Inclined plates 19 are fixedly connected to the inner walls on both sides of the crushing box 1. An opening 21 is opened on one side of the crushing box 1. A screen plate 11 is rotatably connected to the inner wall on one side of the crushing box 1. A collection frame 12 is provided on the lower inner wall of the crushing box 1. A rake assembly is provided on the crushing box 1. The rake assembly includes a reciprocating screw 6 rotatably installed on the crushing box 1. A fixing block 25 is threadedly connected to the reciprocating screw 6. A rake bar 24 is fixedly connected to the lower surface of the fixing block 25.

[0019] A sliding assembly is provided on the crushing box 1. The sliding assembly includes a slide rod 10 slidably installed on the crushing box 1. The slide rod 10 has an L-shaped cross section. One end of the slide rod 10 is fixedly connected to a horizontal plate 20. The horizontal plate 20 is located below two inclined plates 19. A limit groove is opened on one side of the crushing box 1. A limit block 17 is slidably installed in the limit groove. A slot 30 for connecting the slide rod 10 is opened on the limit block 17. A first spring 28 is sleeved on the slide rod 10. One end of the first spring 28 is fixedly connected to the slide rod 10. The other end of the first spring 28 is fixedly connected to the surface of the crushing box 1. Pushing the slide rod 10 causes it to slide relative to the crushing box 1. The first spring 28 deforms. After the horizontal plate 20 moves, it will be located directly below the two inclined plates 19 and fit against the lower surface of the two inclined plates 19, thereby sealing the gap between the two inclined plates 19. Then, pushing the limit block 17 until one end of the slide rod 10 engages with the slot 30 can prevent the slide rod 10 from moving in the opposite direction.

[0020] A groove is provided on one side surface of the crushing box 1, and a bracket 14 is slidably installed in the groove. A limiting plate 16 is fixedly connected to the upper surface of the bracket 14. The upper surface of the limiting plate 16 is in contact with the lower surface of the screen plate 11. A rectangular groove is provided on one side surface of the crushing box 1, and a rectangular block 13 is slidably connected in the rectangular groove. A latch is provided on one side of the rectangular block 13, and one end of the bracket 14 is engaged with the latch. A second spring 31 is fixedly connected to the inner wall of one side of the rectangular groove. The second spring 31 is fixedly connected to the rectangular block 13. When the rectangular block 13 is pulled, the second spring 31 will deform during the sliding process inside the rectangular groove. At the same time, one end of the bracket 14 will disengage from the latch. The bracket 14 and the limiting plate 16 will move vertically downward under the action of gravity. The screen plate 11 will also deflect downward inside the opening 21 under the action of gravity. After the screen plate 11 rotates, it will change from a horizontal state to an inclined state. The larger mirabilite above the screen plate 11 can slide along the screen plate 11 under the action of gravity.

[0021] A lug 8 with an L-shaped cross-section is fixedly connected to one side surface of the crushing box 1. A second motor is fixedly connected to the lug 8. The drive end of the second motor is fixedly connected to the reciprocating lead screw 6. A fixed shaft 3 is rotatably connected to the crushing box 1. A crossbar 15 and multiple striking rods 22 are fixedly connected to the fixed shaft 3. A torsion spring 23 is sleeved on the fixed shaft 3. One end of the torsion spring 23 is fixedly connected to the fixed shaft 3, and the other end of the torsion spring 23 is fixedly connected to the inner wall of the crushing box 1. A vertical groove is opened on one side of the crushing box 1. A moving plate 5 with a T-shaped cross-section is slidably connected in the vertical groove.

[0022] A pressing rod 4 is fixedly connected to the lower surface of the moving plate 5. The lower end of the pressing rod 4 is set as an arc surface, which fits against the upper surface of the crossbar 15. A cam 7 is fixedly connected to the reciprocating screw 6. As the cam 7 rotates together with the reciprocating screw 6, one end of the cam 7 will repeatedly press against and separate from the upper surface of the moving plate 5. When one end of the cam 7 rotates downward against the surface of the moving plate 5, the moving plate 5 moves downward in the vertical groove at the same time. The pressing rod 4 will move downward against the surface of the crossbar 15 without separating from the surface of the crossbar 15, thereby causing the crossbar 15 to rotate downward. The fixed shaft 3 rotates relative to the crushing box 1 at the same time. The torsion spring 23 deforms. After each striking rod 22 rotates together with the fixed shaft 3, it will hit the lower surface of the screen plate 11.

[0023] A telescopic rod 29 is fixedly connected to one inner wall of the crushing box 1. The telescopic end of the telescopic rod 29 is fixedly connected to the fixing block 25. An arc-shaped baffle 26 is fixedly connected to both inner walls of the crushing box 1. The arc-shaped baffle 26 is located directly above the reciprocating screw 6. When the second motor drives the reciprocating screw 6 to rotate, the fixing block 25 will move back and forth along the reciprocating screw 6 during the rotation of the reciprocating screw 6. At the same time, the telescopic rod 29 will expand and contract. The telescopic rod 29 can limit the movement trajectory of the fixing block 25. Under the shielding effect of the arc-shaped baffle 26, the crushed mirabilite can be effectively prevented from falling onto the reciprocating screw 6.

[0024] In this invention, during use, mirabilite is fed into the crushing box 1 from directly above through the feed pipe 9. Two first motors are powered on simultaneously, and each first motor drives the corresponding rotating shaft 18 to rotate. During the rotation of the two crushing rollers 27, the mirabilite is crushed. The crushed raw material falls from the two inclined plates 19 onto the screen plate 11 under the action of gravity. At the same time, the second motor drives the reciprocating screw 6 to rotate. During the rotation of the reciprocating screw 6, the fixed block 25 moves back and forth along the reciprocating screw 6. The telescopic rod 29 simultaneously expands and contracts. As the rake bar 24 moves back and forth with the fixed block 25, the mirabilite accumulated on the screen plate 11 is rake-divided so that mirabilite of appropriate size can pass through the screen holes and fall into the collection frame 12.

[0025] As cam 7 rotates together with reciprocating screw 6, one end of cam 7 repeatedly presses against and separates from the upper surface of moving plate 5. When one end of cam 7 rotates downward against the surface of moving plate 5, moving plate 5 simultaneously moves downward in vertical groove. The pressing rod 4 moves downward against the surface of crossbar 15 without separating from the surface of crossbar 15, causing crossbar 15 to rotate downward. At the same time, fixed shaft 3 rotates relative to crushing box 1, torsion spring 23 deforms, and each striking rod 22 rotates together with fixed shaft 3, thus impacting... On the lower surface of the sieve plate 11, the sieve plate 11 vibrates to facilitate the passage of mirabilite through the sieve holes. After the cam 7 disengages from the moving plate 5, the fixed shaft 3 rotates to the initial position under the elastic force of the torsion spring 23, and the moving plate 5 also moves upward to the initial position. During the rotation of the cam 7, the fixed shaft 3 and multiple striking rods 22 can deflect back and forth multiple times, and the multiple striking rods 22 can strike the sieve plate 11 multiple times, so that the sieve plate 11 has a better screening effect on mirabilite and a better pretreatment effect on mirabilite.

[0026] When there is a large amount of large mirabilite ore above the sieve plate 11, first push the slide rod 10 so that it slides relative to the crushing box 1. The first spring 28 deforms, and after the horizontal plate 20 moves, it will be located directly below the two inclined plates 19 and in contact with the lower surface of the two inclined plates 19, thereby sealing the gap between the two inclined plates 19. Then push the limiting block 17 until one end of the slide rod 10 is engaged with the slot 30, which can prevent the slide rod 10 from moving in the opposite direction. The limiting block 17 can only slide along the limiting groove and cannot be disengaged from the limiting groove. Then pull the rectangular block 13. During the process of the rectangular block 13 sliding inside the rectangular groove, the second spring 31 will deform, and one end of the bracket 14 will disengage from the slot at the same time. The bracket 14 and the limiting block 13 will then disengage from the slot. Under the influence of gravity, the position plate 16 will move vertically downwards, and the screen plate 11 will also deflect downwards inside the opening 21 under the influence of gravity. After the screen plate 11 rotates, it will change from a horizontal state to an inclined state. The larger mirabilite above the screen plate 11 can slide along the screen plate 11 under the influence of gravity and be discharged through the opening 21 until it falls into the collection box (not shown). Then, the position plate 16 is moved upwards again, and the screen plate 11 is set horizontally. The horizontal plate 20 is moved to the initial position, so that the newly crushed mirabilite can be screened. The mirabilite collected in the collection box can be directly poured into the feed pipe 9 for secondary crushing. The operation is relatively convenient and quick, and the crushing efficiency of mirabilite is high, which is beneficial to the use of the crushing device.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
