Description

Technical Field

[0001] The invention relates to the technical field of fertilizer production, and in particular to a crushing device for fertilizer production. Background Art

[0002] Fertilizer is an essential substance in agricultural production activities. It promotes plant growth by supplementing the nutrients lacking in the soil. In fertilizer production, many raw materials appear in a large volume. In order to ensure the uniform mixing of various components in fertilizer production, these raw materials need to be crushed into a small enough volume. For this purpose, a crushing device is required.

[0003] However, in order to ensure that the raw materials are fully crushed, the current fertilizer crushing device usually occupies a large space in the crushing box for the crushing components to ensure that there are no dead angles in the crushing. This results in a very small proportion of the storage space for the raw materials, resulting in frequent feeding and shutdown of the machine during the crushing process, which affects the efficiency of the crushing. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a crushing device for fertilizer production in view of the above-mentioned technical deficiencies, which can greatly increase the proportion of space occupied by fertilizer raw materials in the crushing box, reduce the frequency of feeding and discharging, and improve the efficiency of the crushing work.

[0005] The technical solution adopted by the present invention is: to provide a crushing device for fertilizer production, comprising a support base; the upper end of the support base is connected to a crushing box arranged in the front-back direction; the crushing box is a rectangular parallelepiped structure, and its left and right sides are arc-shaped; the upper end of the crushing box is connected to a feed inlet; the lower end of the crushing box is connected to a discharge control component; and a mobile crushing component is arranged on the crushing box;

[0006] The material discharging control assembly comprises a guide hopper fixed at the bottom of the crushing box; the upper end of the guide hopper is connected to the lower end of the crushing box through a discharging port; a discharging port is provided at the lower end of the side of the guide hopper; a blocking plate is slidably connected in the guide hopper along the height direction; the blocking plate is matched with the discharging port; a first telescopic device for controlling the sliding of the blocking plate is fixed at the bottom of the guide hopper;

[0007] The mobile crushing assembly includes a mounting frame sleeved on the outside of the crushing box; the front and rear ends of the mounting frame slide along the left and right directions respectively and penetrate the front and rear ends of the crushing box; a second telescopic device for controlling the left and right sliding of the mounting frame is fixed on the crushing box; a support shaft is arranged in the middle of the crushing box along the front and rear directions; the support shaft is rotatably connected to the middle of the mounting frame; the support shaft is driven by a power motor fixed to the mounting frame; a plurality of first crushing knives and a plurality of second crushing knives are evenly distributed on the support shaft from front to back; the first crushing knives and the second crushing knives are arranged one by one at intervals; the middle part of the first crushing knife is sleeved and fixed on the support shaft; the middle part of the second crushing knife is rotatably sleeved on the support shaft; the ends of the plurality of second crushing knives are connected by a connecting strip; the second crushing knives at the front and rear ends are respectively connected to the mounting frame through fixed blocks; the lengths of the first crushing knife and the second crushing knife are both smaller than the height inside the crushing box.

[0008] To further optimize the technical solution, a crushing box of a crushing device for fertilizer production has an adjustment shaft arranged along the front-to-back direction fixed to the bottom through a support; the adjustment shaft is rotatably connected to the support base and is driven by an adjustment motor fixed to the support base.

[0009] To further optimize the technical solution, a discharge port of a crushing device for fertilizer production is correspondingly opened at the bottom of the crushing box along the front-to-back direction.

[0010] To further optimize the technical solution, a plurality of arc-shaped third crushing knives are evenly fixed on the left and right sides of a crushing box of a crushing device for fertilizer production along the front-to-back direction; the third crushing knives are staggered one by one with the second crushing knives in the front-to-back direction.

[0011] The beneficial effects of the present invention are:

[0012] The ends of the second crushing knife are connected by a connecting strip, and the second crushing knives at the front and rear ends are respectively connected to the mounting frame through fixed blocks, and the middle part of the second crushing knife is rotatably sleeved on the support shaft. The second crushing knife and the mounting frame are relatively fixed, and the rotation of the support shaft will not drive the second crushing knife to rotate; the middle part of the first crushing knife is sleeved and fixed on the support shaft, and the first crushing knife and the second crushing knife are arranged one by one, and the rotation of the support shaft can drive the first crushing knife to rotate. The rotating first crushing knife and the fixed second crushing knife cooperate to achieve cutting and crushing of the raw materials.

[0013] The front and rear ends of the mounting frame slide in the left and right directions respectively and penetrate the front and rear ends of the crushing box. A second telescopic device for controlling the left and right sliding movement of the mounting frame is fixed on the crushing box. The left and right sliding movement of the mounting frame is controlled by the second telescopic device, which can drive the first crushing knife and the second crushing knife to move left and right inside the crushing box, thereby reducing the crushing dead angle while increasing the proportion of space occupied by raw materials in the crushing box, thereby ensuring sufficient crushing of the raw materials.

DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] like Figure 1 As shown, a crushing device for fertilizer production includes a support base 1; the upper end of the support base 1 is connected to a crushing box 2 arranged in the front-to-back direction; the crushing box 2 is a rectangular parallelepiped structure, and its left and right sides are arc-shaped; the upper end of the crushing box 2 is connected to a feed port 3; the lower end of the crushing box 2 is connected to a discharge control component; and a mobile crushing component is arranged on the crushing box 2;

[0020] like Figure 2-3 As shown, the discharge control assembly includes a guide hopper 4 fixed at the bottom of the crushing box 2; the upper end of the guide hopper 4 is connected to the lower end of the crushing box 2 through a discharge port 5; a discharge port 6 is opened at the lower end of the side of the guide hopper 4; a blocking plate 7 is slidably connected in the height direction of the guide hopper 4; the blocking plate 7 is correspondingly matched with the discharge port 5; a first telescopic device 8 for controlling the sliding of the blocking plate 7 is fixed at the bottom of the guide hopper 4;

[0021] like Figure 1-3As shown, the mobile crushing assembly includes a mounting frame 9 sleeved on the outside of the crushing box 2; the front and rear ends of the mounting frame 9 slide through the front and rear ends of the crushing box 2 respectively along the left and right directions; a second telescopic device 10 for controlling the left and right sliding of the mounting frame 9 is fixed on the crushing box 2; a support shaft 11 is arranged in the middle of the crushing box 2 along the front and rear directions; the support shaft 11 is rotatably connected to the middle of the mounting frame 9; the support shaft 11 is driven by a power motor 12 fixed to the mounting frame 9; a plurality of first crushing knives 13 and a plurality of second crushing knives 14 are evenly distributed on the support shaft 11 from front to back; the first crushing knives 13 and the second crushing knives 14 are arranged one by one at intervals; the middle part of the first crushing knife 13 is sleeved and fixed on the support shaft 11; the middle part of the second crushing knife 14 is rotatably sleeved on the support shaft 11; the ends of the plurality of second crushing knives 14 are connected by a fixing strip 15; the second crushing knives 14 at the front and rear ends are respectively connected to the mounting frame 9 through a fixing block 16; the lengths of the first crushing knife 13 and the second crushing knife 14 are both less than the height inside the crushing box 2.

[0022] The fertilizer raw material is transported from the feed port 3 to the crushing box 2 through external conveying equipment, and then the support shaft 11 is driven to rotate by the power motor 12, so that the first crushing knife 13 rotates accordingly. The rotation of the first crushing knife 13 cooperates with the second crushing knife 14 in a fixed state with interval distribution, so that the raw material at the position can be crushed. At the same time, the second telescopic device 10 controls the installation frame 9 to slide left and right (the second telescopic device 10 is preset to continuously retract back and forth), driving the support shaft 11 to move left and right in the crushing box 2, so as to change the crushing position, so that the raw materials at various positions in the crushing box 2 are crushed, reducing the dead angle of crushing (the arc-shaped structure on both sides of the crushing box 2 also reduces the problem of dead angle of crushing), so that the proportion of raw materials in the crushing box 2 occupying a large proportion of space is still ensured. The frequency of feeding and discharging is greatly reduced, and the efficiency of crushing work is significantly improved.

[0023] In addition, in the above process, this "crushing while moving" working mode can also help to stir the raw materials. If multiple raw materials are added at one time, this process can not only crush the raw materials, but also achieve uniform mixing of the multiple raw materials, achieving the technical effect of "one thing for multiple uses".

[0024] After the crushing work is completed, the blocking plate 7 is controlled to move downward by the first telescopic device 8 to release the blockage of the discharge port 5, and the raw materials can enter the guide hopper 4 through the discharge port 5 and then be discharged from the discharge port 6.

[0025] like Figure 2As shown, an adjustment shaft 18 arranged in the front-to-back direction is fixed to the bottom of the crushing box 2 through a support 17; the adjustment shaft 18 is rotatably connected to the support base 1 and driven by an adjustment motor 19 fixed to the support base 1. By driving the adjustment motor 19, the crushing box 2 can be driven to tilt to one side, which helps the raw materials to be discharged more thoroughly from the discharge port 5. In addition, the raw materials in the crushing box 2 can be shaken by adjusting the motor 19 to rotate forward and reversely within a certain range (the adjustment motor 19 can be a servo motor or a stepper motor), which further helps the crushing and mixing of the raw materials.

[0026] like Figure 3 As shown, the discharge port 5 is correspondingly opened at the bottom of the crushing box 2 along the front-to-back direction. The discharge port 5 is correspondingly arranged at the bottom of the crushing box 2 along the front-to-back direction, which can make the discharge more convenient and thorough, and reduce the residue of raw materials near the discharge port 6 inside the crushing box 2.

[0027] like Figure 3 As shown, a plurality of arc-shaped third crushing knives 20 are evenly fixed on the left and right sides of the crushing box 2 along the front-to-back direction; the third crushing knives 20 are staggered one by one with the second crushing knives 14 in the front-to-back direction. The third crushing knives 20 can cooperate with the rotating second crushing knives 14 to crush the raw materials remaining on both sides of the crushing box 2, further improving the efficiency of complete crushing.
