Description

Technical Field

[0001] This utility model relates to the technical field of water-soluble fertilizer production equipment, specifically to a water-soluble fertilizer raw material clot crushing device. Background Technology

[0002] Water-soluble fertilizer is a highly efficient and easily absorbed fertilizer widely used in modern agricultural production. However, during production, storage, and transportation, the raw materials for water-soluble fertilizer are prone to clumping and solidification due to environmental factors such as temperature and humidity. This not only affects the effectiveness of the water-soluble fertilizer but also increases production costs and operational difficulties.

[0003] Currently, the crushing of agglomerated and caking raw materials mainly relies on manual labor with auxiliary tools, which is inefficient and inconvenient. Existing crushing devices lack effective return mechanisms, failing to achieve automatic secondary crushing of incompletely crushed lumps, resulting in low processing efficiency. Furthermore, the existing vibrating screening mechanism is not tightly integrated with the crushing mechanism, making continuous and efficient agglomeration and screening difficult. Therefore, there is an urgent need to develop a crushing device specifically for agglomerated water-soluble fertilizer raw materials, capable of efficiently addressing the agglomeration problem that occurs during storage and improving the utilization efficiency of water-soluble fertilizer raw materials. Utility Model Content

[0004] The purpose of this invention is to provide a device for crushing water-soluble fertilizer raw material lumps, so as to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water-soluble fertilizer raw material agglomerate crushing device, comprising a vibrating screening mechanism, a crushing mechanism, and a return material mechanism. One end of the vibrating screening mechanism is connected to the crushing mechanism, and a return material mechanism is provided on one side of the crushing mechanism. The vibrating screening mechanism includes a screening box, and a vibrating screen is inclinedly arranged inside the screening box. The crushing mechanism includes a crushing box, and a crushing roller is arranged inside the crushing box. The end of the vibrating screen is located above the crushing roller. A screen is inclinedly arranged on the inner side of the lower end of the crushing box. A return material port is provided through the side wall of the crushing box, and the end of the screen passes through the return material port. The return material mechanism includes a return material trough, and a return material trough is provided below the end of the screen.

[0006] Furthermore, a storage box is provided at the lower end of the screening box, a vibration motor is fixedly installed on the outer wall of the storage box, a first support is fixedly installed on the outer periphery of the screening box, and shock-absorbing springs are symmetrically arranged on the outer side wall of the screening box, with the lower end of the shock-absorbing springs fixedly installed on the first support.

[0007] Furthermore, a drive motor is fixedly installed on both side walls of the crushing box, and the output end of the drive motor is connected to the crushing roller. A finished product storage box is installed at the lower end of the crushing box and below the screen. A discharge port is installed at the lower end of the finished product storage box. A second support is fixedly installed at the lower end of the crushing box.

[0008] Furthermore, a fixed box is fixedly installed on the outer periphery of the return chute, and a screw conveyor is connected to the side wall of the return chute.

[0010] Furthermore, the screen and the vibrating screen have the same aperture.

[0011] This utility model has the following beneficial effects:

[0012] The beneficial effects of this invention are as follows: The water-soluble fertilizer powder raw material is initially screened using a vibrating screening mechanism, separating lumps from the powder. Qualified powder directly enters the storage bin for subsequent use, while lumps are crushed by the crushing rollers in the crushing mechanism via the end of the vibrating screen. The crushed material undergoes a second screening via a screen. Qualified powder enters the finished product storage bin along with the initially screened qualified powder for subsequent use. Unqualified powder enters the return trough through the return port, and is then sent back to the crushing mechanism by a screw conveyor for further crushing until it meets the screening requirements. This cyclical screening and crushing process ensures that all raw materials reach a qualified powder state, effectively solving the problem of lumps in water-soluble fertilizer powder raw materials and guaranteeing the quality of raw materials used in subsequent water-soluble fertilizer production. Simultaneously, the device has a compact structure, is easy to operate, and improves the efficiency and quality of water-soluble fertilizer raw material processing. Attached Figure Description

One end of the vibrating screening mechanism 1 is connected to the crushing mechanism 2, and the return material mechanism 3 is provided on one side of the crushing mechanism 2.

[0024] The vibrating screening mechanism 1 includes a screening box 101, a vibrating screen 106 is inclinedly arranged inside the screening box 101, a storage box 103 is arranged at the lower end of the screening box 101, a vibrating motor 105 is fixedly arranged on the outer wall of the storage box 103, a first support 104 is fixedly arranged on the outer periphery of the screening box 101, and shock-absorbing springs 102 are symmetrically arranged on the outer side wall of the screening box 101, with the lower end of the shock-absorbing spring 102 fixedly arranged on the first support 104.

[0025] The crushing mechanism 2 includes a crushing box 201. A crushing roller 203 is installed inside the crushing box 201. The end of a vibrating screen 106 is located above the crushing roller 203. A screen 202 is inclinedly installed on the inner side of the lower end of the crushing box 201. A return port 206 is provided through the side wall of the crushing box 201, and the end of the screen 202 passes through the return port 206. Drive motors 204 are fixedly installed on both ends of the crushing box 201. The output end of the drive motors 204 is connected to the crushing roller 203. A finished product storage box 208 is installed at the lower end of the crushing box 201, below the screen 202. A discharge port 207 is provided at the lower end of the finished product storage box 208. A second support 205 is fixedly installed at the lower end of the crushing box 201. Springs 209 are symmetrically arranged on the screen 202 at the return port 206. The screen 202 and the vibrating screen 106 have the same aperture.

[0026] The return material mechanism 3 includes a return material trough 301, which is located below the end of the screen 202. A fixed box 302 is fixedly installed on the outer periphery of the return material trough 301. A screw conveyor 303 is connected to the side wall of the return material trough 301. The bottom of the screw conveyor 303 is fixedly installed at the bottom of the fixed box 302. A motor is fixedly installed at the top of the screw conveyor 303. A discharge pipe 305 is installed through the upper side wall of the screw conveyor 303. A fixed support plate 306 is also installed at the upper end of the screw conveyor 303, and the fixed support plate 306 is connected to the crushing box 201.

[0027] The working principle of the water-soluble fertilizer raw material clot crushing device in this embodiment is as follows:

[0028] Water-soluble fertilizer raw materials enter through the upper part of the screening box 101. Under the action of the vibrating motor 105, the screening box 101 vibrates, causing the water-soluble fertilizer raw materials on the vibrating screen 106 to be screened. Smaller particles of the water-soluble fertilizer raw materials on the vibrating screen 106 fall directly into the storage box 103, while larger particles or lumps slide along the inclined vibrating screen 106 to the end. The damping spring 102 can reduce the vibration impact of the vibrating screening mechanism 1 on the overall device and improve the stability of the equipment.

[0029] Larger particles or lumps sliding off the end of the vibrating screen 106 enter the crushing chamber 201 and fall onto the crushing roller 203. The drive motor 204 drives the crushing roller 203 to rotate, crushing the water-soluble fertilizer raw material lumps. The crushed material falls onto the inclined screen 202, and materials that meet the particle size requirements fall through the screen 202 into the finished product storage box 208, and are finally discharged through the discharge port 207.

[0030] Larger particles that fail to pass through screen 202 slide along the inclined screen 202 to the end and enter the return chute 301 through the return port 206. The spring 209 installed at the return port 206 on screen 202 reduces wear at the contact point between screen 202 and return port 206, extending the equipment's service life. Material in the return chute 301 enters the screw conveyor 303, which, driven by a motor, conveys the material upwards and finally returns it to the crushing chamber 201 through the discharge pipe 305 for secondary crushing, forming a closed-loop processing system.

[0031] Screen 202 and vibrating screen 106 adopt the same aperture design, ensuring the consistency of screening standards throughout the system and improving the uniformity of the finished product. Fixed support plate 306 connects screw conveyor 303 and crushing box 201, enhancing the stability of the overall structure.

[0032] The water-soluble fertilizer raw material agglomerate crushing device in this embodiment achieves efficient crushing and screening of water-soluble fertilizer raw material agglomerates through the coordinated operation of the vibrating screening mechanism 1, the crushing mechanism 2, and the return material mechanism 3. The device has a compact structure, is easy to operate, and can effectively deal with the raw material agglomeration problem that occurs during the production of water-soluble fertilizers, thereby improving the production efficiency and product quality of water-soluble fertilizers.

[0033] It should be noted that Example 1 is a type of water-soluble fertilizer raw material clot crushing device.
