Description

Technical Field

[0001] This utility model relates to the technical field of crushing equipment, and in particular to a dual-shaft differential shearing compound fertilizer crushing device. Background Technology

[0002] During the production and processing of compound fertilizers, some organic matter that needs to be crushed is added, including humic acid, livestock and poultry manure, straw charcoal, soybean meal, etc. These raw materials need to be crushed before use, which requires a crusher. Existing crushers are mainly dual-shaft differential speed shear crushers. For example, patent application CN201921786748.3 discloses a feed crusher for uniform granulation. In this patent, the raw material enters through the upper end of the feed hopper 9, falls through the second baffle 10 to the highest point of the screen 11, and due to the vibration generated during machine operation, the raw material passes through the screen 11 under the influence of vibration and gravity. Raw materials of acceptable size fall through screen 11, while larger impurities are discharged through hopper 13. Qualified raw materials fall through the third baffle 12 to one side of impeller feeder 20. The raw materials are evenly discharged through impeller feeder 20. After magnetic impurities are attracted by magnet 21, they fall evenly onto coarse roller 3 through discharge pipe 23. After being crushed by coarse roller 3, they fall between two fine rollers 5 through the first baffles on both sides. They are then finely crushed by fine roller 5. The coarse roller 3 and fine roller 5 can be finely adjusted by adjusting screw 15 without affecting the transmission belt 8. Sampling and inspection can be carried out through sampling port 6.

[0003] During the operation of existing crushers, some raw materials may not be completely crushed and fall through the gaps between the blades. To solve this problem, existing raw materials need to be crushed a second time, which requires transferring the raw materials to the feeding position. The current transfer method is to manually push carts, which is inefficient and labor-intensive. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a dual-axis differential shear compound fertilizer crushing device, so as to solve the problems of low efficiency and high labor consumption in the transfer method of secondary crushing of compound fertilizer raw materials in the prior art described in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-axis differential shear type compound fertilizer pulverizing device, comprising...

[0006] The crusher body has a feed hopper at the upper port;

[0007] A filter barrel is installed at the lower port of the crusher body and connected to the lower port of the crusher body. The lower port of the filter barrel is equipped with a discharge hopper.

[0008] The conveyor box has one side wall connected to the feed hopper and the filter barrel, respectively.

[0009] Conveyor belt, installed inside the conveyor box;

[0010] Several baffles are rotatably mounted on the surface of the conveyor belt to carry raw materials into the feed hopper;

[0011] A baffle, inclined and set inside the filter barrel, has several filter holes.

[0012] Preferably, the inner wall of the filter barrel is connected to the baffle via a connecting rod.

[0013] Preferably, a vibrator is also provided at the bottom of the baffle.

[0014] Preferably, one end of the baffle is rotatably connected to the conveyor belt, and a support plate is provided on the conveyor belt at the position corresponding to the baffle. The support plate and the baffle are connected by several springs. A positioning plate is provided on the inner wall of the conveyor box, and a limit roller is provided on the positioning plate. The limit roller is directly opposite the end of the baffle away from the conveyor belt.

[0015] The beneficial effects of adopting the above technical solutions are:

[0016] This application uses the filter holes of the baffle to transport large particles that do not meet the crushing requirements to the conveyor box, so that the raw material falls onto the baffle screen. Then the conveyor belt sends the baffle screen to the feed hopper. Under the obstruction of the limit roller, the baffle screen will rotate, causing the baffle screen to tilt, so that the raw material on the baffle screen will slide into the feed hopper for secondary crushing.

[0021] The components include: crusher body 10, feed hopper 20, filter barrel 30, discharge hopper 31, baffle 40, filter hole 41, connecting rod 42, vibrator 50, conveyor box 60, conveyor belt 70, baffle net 80, spring 81, support plate 82, limit roller 90, and positioning plate 91. Detailed Implementation

[0022] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-4 In this first embodiment, a dual-shaft differential shearing compound fertilizer crushing device includes a crusher body 10, with a feed hopper 20 at the upper port.

[0024] A filter barrel 30 is located at the lower port of the crusher body 10 and is connected to the lower port of the crusher body 10. A discharge hopper 31 is provided at the lower port of the filter barrel 30.

[0025] The conveyor box 60 has one side wall connected to the feed hopper 20 and the filter barrel 30 respectively;

[0026] Conveyor belt 70 is installed inside conveyor box 60;

[0027] Several baffles 80 are rotatably mounted on the surface of the conveyor belt 70 to carry raw materials into the feed hopper 20;

[0028] A baffle 40 is inclinedly disposed inside the filter barrel 30, and the baffle 40 has a plurality of filter holes 41.

[0029] This embodiment is implemented as follows:

[0030] In use, the raw material is poured into the feed hopper 20. The raw material enters the crusher body 10 from the feed hopper 20 for crushing, and then falls onto the baffle 40. After being filtered by the filter holes 41 on the baffle 40, the small particles of raw material pass through the filter holes 41, while the large particles are blocked by the baffle 40 and slide down onto the baffle screen 80. The conveyor belt 70 drives the baffle screen 80 to rotate clockwise, so that the baffle screen 80 carries the large particles of raw material to the position of the feed hopper 20. At this time, the baffle screen 80 rotates on the conveyor belt 70, so that the raw material on the baffle screen 80 slides into the feed hopper 20 for secondary crushing.

[0031] Please see Figure 2 The inner wall of the filter barrel 30 is connected to the baffle 40 via a connecting rod 42.

[0032] The stability of the baffle 40 can be increased by the connecting rod 42.

[0033] Please see Figure 2 A vibrator 50 is also installed at the bottom of the baffle 40.

[0034] The vibrator 50 can prevent the raw material from clogging the filter hole 41 and also facilitate the movement of the raw material on the baffle 40.

[0035] Please see Figure 2 , 3One end of the baffle 80 is rotatably connected to the conveyor belt 70. A support plate 82 is provided on the conveyor belt 70 at the position corresponding to the baffle 80. The support plate 82 and the baffle 80 are connected by several springs 81. A positioning plate 91 is provided on the inner wall of the conveyor box 60. A limit roller 90 is provided on the positioning plate 91. The limit roller 90 is directly opposite the end of the baffle 80 away from the conveyor belt 70.

[0036] The support plate 82 and the baffle 80 are connected by the spring 81. When the baffle 80 moves to the position of the limiting roller 90, it will be blocked by the limiting roller 90, causing the baffle 80 to rotate and compress the spring 81. When the angle of rotation of the baffle 80 is large enough, the baffle 80 will pass the limiting roller 90. At this time, under the reset action of the spring 81, the baffle 80 returns to its original state.

[0037] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
