Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, and in particular to a crushing device for fertilizer production. Background Technology

[0002] Crushing is a crucial step in fertilizer production, used to process raw materials or agglomerated semi-finished products to the appropriate particle size. To guide the material, prevent splashing, and ensure smooth feeding, a feed hopper is usually installed at the feed inlet of the crushing device. Traditionally, feed hoppers are directly fixed with bolts.

[0003] However, bolt-fixed installation is time-consuming and labor-intensive. Each time the feed hopper is installed or replaced, operators need to align each bolt hole and tighten multiple bolts, resulting in a large workload. Similarly, disassembly is inconvenient when performing equipment maintenance, cleaning, or replacing the feed hopper. Therefore, there is an urgent need for a crushing device for fertilizer production that facilitates the assembly of the feed hopper. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a crushing device for fertilizer production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A crushing device for fertilizer production includes a crushing device body, a detachable feed hopper mounted on the feed inlet of the crushing device body, and an installation cavity adapted to the feed inlet on the feed hopper; movable plates are movably mounted on both sides of the feed hopper via screws, locking plates are movably mounted on the movable plates, and multiple locking pins are fixedly mounted on the movable plates, with an inner locking cavity adapted to the corresponding locking pins on the feed inlet.

[0006] In addition, a preferred structure is that both sides of the feed hopper are rotatably equipped with lead screws, and the movable plates reciprocate through the lead screws.

[0007] Furthermore, in a preferred configuration, the feed hopper has external clamping cavities on both sides of the lead screw, and the clamping pins pass through the external clamping cavities.

[0008] In addition, a preferred structure is that multiple fixed seats are fixedly installed on one side of the movable plate on the feed hopper, and each fixed seat is provided with a locking cavity.

[0009] In addition, a preferred structure is that the movable plate has multiple through cavities, and the locking plate is fixedly provided with multiple locking pins, and both the through cavities and the locking cavities are adapted to the locking pins.

[0010] Furthermore, in a preferred configuration, the movable plate has multiple spring cavities, each containing an outwardly mounted spring, and the other end of each spring is connected to a locking plate.

[0011] The beneficial effects of this utility model are as follows: the crushing device body can realize the crushing production process of fertilizer. By adapting and locking the clamping column and the inner clamping cavity, and cooperating with the quick locking between the locking column and the locking cavity, the traditional bolt connection method is replaced, realizing the quick assembly and disassembly of the feed hopper, which is convenient for users to operate.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-6 A crushing device for fertilizer production includes a crushing device body 1. A detachable feed hopper 2 is mounted on the feed inlet 11 of the crushing device body 1. The feed hopper 2 has an installation cavity 21 adapted to fit the feed inlet 11. Movable plates 4 are movably mounted on both sides of the feed hopper 2 via screws. Locking plates 5 are movably mounted on the movable plates 4. Multiple locking pins 43 are fixedly mounted on the movable plates 4, and an inner locking cavity 12 is adapted to fit the locking pins 43 on the feed inlet 11.

[0016] Both sides of the feed hopper 2 are rotatably equipped with lead screws 3, and the movable plates 4 reciprocate via the lead screws 3. The movable plates 4 are provided with lead screw cavities adapted to the lead screws 3, so that the movement of the movable plates 4 can be realized by the rotation of the lead screws 3. A threaded self-locking mechanism is provided between them. These are all existing technologies, so they will not be described in detail.

[0017] The feed hopper 2 has external clamping cavities 22 on both sides of the lead screw 3, and the clamping posts 43 pass through the external clamping cavities 22. The external clamping cavities 22 guide the clamping posts 43 to ensure the stability of the movable plate 4 during movement.

[0018] The feed hopper 2 has multiple fixed seats 23 fixedly installed on one side of the movable plate 4, and each fixed seat 23 has a locking cavity 231. The movable plate 4 has multiple through cavities 41, and the locking plate 5 has multiple locking pins 51 fixedly installed, with both the through cavities 41 and the locking cavities 231 being adapted to the locking pins 51. By passing the locking pins 51 through the through cavities 41 and locking them into the locking cavities 231, the movable plate 4 can be locked.

[0019] The movable plate 4 has multiple spring cavities 42, each containing an outwardly extending spring 421, the other end of which is connected to the locking plate 5. The springs 421 ensure that the locking pin 51 is stably engaged within the locking cavity 231. Notably, the springs 421 are high-strength anti-vibration springs, ensuring sufficient preload even under extreme vibration conditions.

[0020] In this embodiment, the raw materials of fertilizer can be crushed by the crushing device body 1, which is the prior art and therefore will not be described in detail.

[0021] When assembling the feed hopper 2, simply place the mounting cavity 21 on the feed inlet 11 to achieve initial positioning of the feed hopper 2. Then, simply pull out the locking plates 5 on both sides, at which point the springs 421 are stretched. Next, simply turn the screw 3 by the knob to move the movable plate 4 inward, at which point the locking pin 43 moves synchronously, thus locking the locking pin 43 into the inner locking cavity 12.

[0022] When the locking pin 43 is fully inserted into the inner locking cavity 12, the through cavity 41 and the locking cavity 231 are aligned. At this point, the user only needs to loosen the locking plate 5. The locking plate 5 will automatically reset due to the elastic force of the spring 421, causing the locking pin 51 to move synchronously. The locking pin 51 can then pass through the through cavity 41 and be locked into the locking cavity 231, thereby fixing the movable plate 4 and ensuring the installation stability of the feed hopper 2. The user then only needs to repeat this operation on the other side of the feed hopper 2.

[0023] Furthermore, when the user needs to disassemble the feed hopper 2, simply pull the locking plate 5 outward. Then, simply rotate the screw 3 in the opposite direction using the knob to move the movable plate 4 outward, thereby releasing the mutual locking between the locking post 43 and the inner locking cavity 12. The user then only needs to repeat this operation on the other side of the feed hopper 2, and finally the feed hopper 2 can be directly removed.

[0024] In this utility model, the crushing production process of fertilizer can be realized through the crushing device body 1. The fitting and locking between the clamping column 43 and the inner clamping cavity 12, and the quick locking between the locking column 51 and the locking cavity 231, replace the traditional bolt connection method, realize the quick assembly and disassembly of the feed hopper 2, and facilitate the operation of the user.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
