[0003] Existing technologies such as the invention with the publication number CN211801575U disclose a crusher. This patent uses a feeder to transport materials into a roll screening machine. The roll screening machine includes a housing and a row of roll shafts arranged inside the housing. The row of roll shafts is used for screening materials and transporting the screened materials to a crushing device. An outlet is provided on the housing, and the outlet is located below the row of roll shafts and is connected to a discharging device. The crushing device is used for crushing the materials screened by the roll screening machine, and the crushing device is connected to the discharging device. This crusher can effectively improve the crushing efficiency and increase the crushing output, and solves the problems that when the materials are in a wet state or under rainy conditions, the wet materials pass through a vibrating screen, and due to vibration, the fine materials are segregated, and the more they vibrate, the more compact they become, resulting in the gaps being blocked by the fine materials, losing the screening function, and even hindering the material transportation, seriously affecting the crushing ratio of the crusher and the production of the equipment.

[0004] The inventor found in daily work that there is a problem that during the process of processing heavy calcium carbonate fine powder, because the stirring force of the crusher is too large, the heavy calcium carbonate fine powder is easily thrown out from the feed hopper. Content of the Utility Model

[0005] The purpose of the utility model is to provide a crushing device for processing heavy calcium carbonate fine powder, which solves the problem that during the process of processing heavy calcium carbonate fine powder in the prior art, because the stirring force of the crusher is too large, the heavy calcium carbonate fine powder is easily thrown out from the feed hopper.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0011] Preferably, one end of the shaft rod is rotatably connected to the side wall of the baffle plate, and the other end is bolt-fixed to the inner wall of the feed inlet. The torsion spring is arranged on the outer circle of the shaft rod, and one end of the torsion spring is elastically connected to the inner wall of the discharge port, and the other end is elastically connected to the side wall of the baffle plate.

[0012] Preferably, a material receiving plate is arranged on one side of the inclined plate. The bottom of the material receiving plate is connected to the bottom of the inner cavity of the feed inlet. A docking groove is opened on one bottom side of the material receiving plate. The feeding bin is inclined, and one side of the opening of the feeding bin is fixedly connected with a docking plate adapted to the docking groove.

[0013] Preferably, the baffle structure includes a baffle plate. A transverse groove adapted to the baffle plate and communicating with the opening is opened on one top side of the feeding bin. One top side of the baffle plate is connected with a fixing plate. A side plate connected to the side wall of the feeding bin is arranged at the bottom of the fixing plate.

[0016] The utility model has at least the following beneficial effects:

[0017] Through the arrangement of the baffle plate and the inclined plate, the heavy calcium carbonate fine powder raw material is put into the inside of the feeding bin. The feeding bin is driven to move up and down by the lifting assembly, so that the feeding bin moves to the position of the feed inlet. The outlet position is opened through the cooperation of the baffle structure, so that the heavy calcium carbonate fine powder raw material enters the inside of the feed inlet. When the heavy calcium carbonate fine powder raw material contacts the baffle plate, it will drive the baffle plate to rotate, so that the heavy calcium carbonate fine powder raw material enters the inside of the feed inlet through the position of the baffle plate. After the heavy calcium carbonate fine powder raw material passes through, the baffle plate is reset due to the cooperation of the torsion spring. Therefore, when the heavy calcium carbonate fine powder raw material is crushed, the position of the feed inlet is blocked by the baffle plate, effectively avoiding the situation of the heavy calcium carbonate fine powder being thrown out.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] Refer to Figures 1-5 , a crushing device for processing heavy calcium carbonate fine powder, including a crusher 4 and a conveyor belt 5;

[0027] On one side of the top of the crusher 4, there is a feed inlet, and on the other side of the bottom, there is a discharge outlet. The conveyor belt 5 is arranged at the discharge outlet;

[0028] On one side of the crusher 4 away from the conveyor belt 5, there is a U-shaped lifting frame 1. Inside the lifting frame 1, there is a feeding bin 2. On one side of the feeding bin 2, there is an outlet, and a material blocking structure is arranged at the outlet. The feeding bin 2 is connected to the bottom of the inner cavity of the lifting frame 1 through a lifting component;

[0029] Inside the feed inlet, there is a baffle plate 3. Both top sides of the baffle plate 3 are rotatably connected to the inner wall of the feed inlet through shaft rods 9 and torsion springs 10. At the bottom of one side of the baffle plate 3, there is an inclined plate 8 connected to the bottom of the inner cavity of the feed inlet. Specifically, through the arrangement of the baffle plate 3 and the inclined plate 8, the heavy calcium carbonate fine powder raw material is put into the inside of the feeding bin 2. The feeding bin 2 is driven by a lifting assembly to move up and down, so that the feeding bin 2 moves to the position of the feed inlet. Through the cooperation of the material blocking structure, the outlet position is opened, so that the heavy calcium carbonate fine powder raw material enters the inside of the feed inlet. When the heavy calcium carbonate fine powder raw material contacts the baffle plate 3, it will drive the baffle plate 3 to rotate, so that the heavy calcium carbonate fine powder raw material enters the inside of the feed inlet through the position of the baffle plate 3. After the heavy calcium carbonate fine powder raw material passes through, the baffle plate 3 is reset due to the cooperation of the torsion spring 10. Therefore, when the heavy calcium carbonate fine powder raw material is crushed and processed, the position of the feed inlet is blocked by the baffle plate 3, effectively avoiding the situation of the heavy calcium carbonate fine powder being thrown out.

[0030] Further, one end of the shaft rod 9 is rotatably connected to the side wall of the baffle plate 3, and the other end is bolted and fixed to the inner wall of the feed inlet. The torsion spring 10 is arranged on the outer circle of the shaft rod 9, and one end of the torsion spring 10 is elastically connected to the inner wall of the discharge port, and the other end is elastically connected to the side wall of the baffle plate 3.

[0031] Further, on one side of the inclined plate 8, there is a material receiving plate 6. The bottom of the material receiving plate 6 is connected to the bottom of the inner cavity of the feed inlet. On one side of the bottom of the material receiving plate 6, there is a docking groove 7. The feeding bin 2 is inclined, and on one side of the opening of the feeding bin 2, there is a docking plate 17 fixedly connected and adapted to the docking groove 7.

[0032] Further, the material blocking structure includes a baffle plate 20. On one side of the top of the feeding bin 2, there is a transverse groove 16 adapted to the baffle plate 20 and communicating with the opening. On one side of the top of the baffle plate 20, there is a fixing plate 19. At the bottom of the fixing plate 19, there is a side plate 15 connected to the side wall of the feeding bin 2. At the top of the side plate 15, there is a push-pull cylinder 18. The output end of the push-pull cylinder 18 is connected to the bottom of the fixing plate 19.

[0033] Further, on both sides of the lifting frame 1, there are sliding grooves 13. On both sides of the feeding bin 2, there are sliding blocks 14 fixedly connected and slidably connected to the sliding grooves 13.

[0034] Further, the lifting assembly includes a lifting cylinder 11 installed inside the lifting frame 1. The output end of the lifting cylinder 11 is connected to a connecting frame 12. One end of the connecting frame 12 is connected to the bottom of the feeding bin 2.

[0035] In summary: Through the settings of the shaft rod 9 and the torsion spring 10, it is convenient to realize the rotation and reset of the baffle plate 3. While the inclined plate 8 facilitates the passage of materials, it can also limit and block the baffle plate 3. Through the settings of the material receiving plate 6 and the docking plate 17, when the feeding bin 2 moves, when the docking plate 17 is docked with the docking groove 7 at the bottom of the material receiving plate 6, it means that the feeding bin 2 has moved into place, which is convenient for controlling the position of the feeding bin 2. At the same time, after the docking plate 17 is docked with the material receiving plate 6, the feeding accuracy can be improved and material spillage can be avoided. Through the settings of the fixing plate 19 and the side plate 15, it is convenient to realize the lifting of the baffle 20 driven by the push-pull cylinder 18, so as to control the opening position and opening and closing. Through the settings of the chute 13 and the slider 14, it is convenient to realize the lifting and moving of the feeding bin 2 inside the lifting frame 1. Through the setting of the lifting cylinder 11, it is convenient to realize the lifting and moving of the feeding bin 2.
