Description

Technical Field

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

[0002] An organic fertilizer crusher is a device specifically designed to crush large pieces of fertilizer or raw materials into small particles or powder. It is widely used in agriculture, fertilizer production, and organic fertilizer processing. Its main function is to improve the solubility and utilization rate of fertilizers, facilitating subsequent mixing, granulation, and application.

[0003] Most existing equipment does not effectively integrate multi-stage crushing and screening functions, and often adopts a step-by-step independent operation method, which leads to multiple material transfers, low production efficiency, and large footprint. Its screening mechanism is mostly static or vibrating screen, which is difficult to achieve automatic material return for secondary crushing when processing organic fertilizer. This causes the screened organic fertilizer to accumulate continuously, eventually interrupting the screening process and requiring frequent cleaning, which affects the continuity of production. Therefore, this invention is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by providing a crushing device for agricultural organic fertilizer production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A crushing device for agricultural organic fertilizer production includes a support frame, a primary crushing box fixed on the top surface of the support frame, and a secondary crushing box fixed inside the support frame. The primary crushing box has a feed inlet at the top and a discharge outlet at the bottom of the secondary crushing box. The primary crushing box is equipped with a primary crushing component, and the secondary crushing box is equipped with a secondary crushing component and a filtration mechanism in sequence along the material flow direction. The primary crushing component, the secondary crushing component, and the filtration mechanism are connected to a drive mechanism, which can synchronously drive the primary crushing component and the secondary crushing component to operate, and drive the filtration mechanism to rotate relative to the secondary crushing box.

[0006] In the above-mentioned crushing device for agricultural organic fertilizer production, the primary crushing component includes two parallel and rotatably connected primary crushing rollers in the primary crushing box, and the two primary crushing rollers rotate in opposite directions through gear meshing; The bottom of the primary crushing box is fixed with a guide cylinder, the bottom end of which is connected to the feed end of the secondary crushing box.

[0007] In the above-mentioned crushing device for agricultural organic fertilizer production, the secondary crushing component includes two parallel and rotatably connected secondary crushing rollers in the secondary crushing box. The two secondary crushing rollers rotate in opposite directions through gear meshing, and their positions correspond to the bottom of the guide cylinder.

[0008] In the above-mentioned crushing device for agricultural organic fertilizer production, the filtration mechanism includes a filter cylinder rotatably connected to the secondary crushing box. The filter cylinder has multiple filter holes on its wall and multiple material feeding plates for feeding materials are arranged axially on its inner wall.

[0009] In the above-mentioned crushing device for agricultural organic fertilizer production, the driving mechanism includes a first motor, a gear transmission system, a sprocket and chain transmission system, and a ring gear transmission system. The first motor is fixed on the primary crushing box, and its output shaft is connected to one of the primary crushing rollers in the primary crushing assembly. The gear transmission system is used to realize the opposite rotational transmission between the two primary crushing rollers and between the two secondary crushing rollers; The sprocket and chain drive system is located between the primary crushing box and the secondary crushing box, and is used to transmit power from the primary crushing roller to the secondary crushing roller; The gear transmission system includes a driven gear ring fixed to the outer wall of the filter cylinder and a drive gear meshing with the driven gear ring. The drive gear is rotatably connected inside a connecting box fixed to the outer wall of the secondary crushing box. The drive gear obtains power through the intermediate sprocket in the sprocket and chain transmission system, thereby driving the filter cylinder to rotate.

[0010] In the above-mentioned crushing device for agricultural organic fertilizer production, the sprocket and chain drive system includes three sprockets, two chains, and a protective cover. The three sprockets are linked by the chains, and the protective cover is fixed between the primary crushing box and the secondary crushing box. The first sprocket is coaxially connected to the primary crushing roller, the second sprocket is coaxially connected to the secondary crushing roller, and the third sprocket is coaxially connected to the drive gear.

[0011] In the above-mentioned crushing device for agricultural organic fertilizer production, a guide plate is fixed on the inner wall of the primary crushing box and below the feed inlet.

[0012] In the above-mentioned crushing device for agricultural organic fertilizer production, the top of the primary crushing box is fixed with a feed hopper that communicates with the feed inlet.

[0013] Compared with existing technologies, the advantages of this invention are: 1. The primary and secondary crushing chambers are arranged in a three-dimensional layout using a support frame. After the material is fed into the hopper, it is first initially crushed by two primary crushing rollers in the primary crushing assembly. The crushed material then falls into the secondary crushing chamber through a guide cylinder. In the secondary crushing chamber, the material undergoes secondary fine crushing by the secondary crushing rollers in the secondary crushing assembly, and then falls into a continuously rotating filter cylinder for dynamic screening. Qualified fine material passes through the filter holes and is discharged from the outlet, while coarse material is tumbled and thrown onto the secondary crushing rollers by the material guide plate for secondary crushing. This effectively prevents sieve clogging and provides an opportunity for substandard coarse material to be repeatedly crushed. This integrated design of two-stage crushing and dynamic filtration improves the crushing efficiency and product uniformity of organic fertilizer. 2. By employing a single motor fixed to the primary crushing chamber as a single power source, and through a precise mechanical transmission design, all core moving parts can be driven synchronously. Specifically, the motor's power directly drives one primary crushing roller, which in turn drives another primary crushing roller to rotate in opposite directions via a gear transmission system. Simultaneously, power is transmitted from the primary crushing roller to the secondary crushing roller via a sprocket and chain transmission system, driving their operation. The intermediate sprocket in the sprocket and chain transmission system also outputs power to the drive gear. The drive gear rotates within the connecting box and, through meshing with the driven gear ring fixed to the outer wall of the filter cartridge, ultimately converts the rotational motion of the filter cartridge. This one-drive-three-action linkage design greatly simplifies the overall structure, reduces manufacturing costs and energy consumption, and ensures the synchronous coordination of crushing and screening actions at each stage, resulting in high operational reliability.

[0018] Reference Figures 1-8 A crushing device for agricultural organic fertilizer production includes a support frame 1, a primary crushing box 2 fixed to the top surface of the support frame 1, and a secondary crushing box 3 fixed inside the support frame 1. The primary crushing box 2 has a feed inlet at the top and the secondary crushing box 3 has a discharge outlet at the bottom. The primary crushing box 2 contains a primary crushing component, and the secondary crushing box 3 contains a secondary crushing component and a filter mechanism arranged sequentially along the material flow direction. The primary crushing component, the secondary crushing component, and the filter mechanism are connected to a drive mechanism, which can synchronously drive the primary crushing component and the secondary crushing component to operate, and drive the filter mechanism to rotate relative to the secondary crushing box 3.

[0019] The primary crushing assembly includes two parallel and rotatably connected primary crushing rollers 201 inside the primary crushing box 2. The two primary crushing rollers 201 rotate in opposite directions through gear meshing. A guide cylinder 202 is fixed at the bottom of the primary crushing box 2, and the bottom end of the guide cylinder 202 is connected to the feed end of the secondary crushing box 3.

[0020] The secondary crushing component includes two parallel and rotatably connected secondary crushing rollers 301 inside the secondary crushing box 3. The two secondary crushing rollers 301 rotate in opposite directions through gear meshing, and their positions correspond to the bottom of the guide cylinder 202.

[0021] The filtration mechanism includes a filter cylinder 302 rotatably connected to the secondary crushing box 3. The filter cylinder 302 has multiple filter holes on its cylinder wall and multiple material feeding plates 303 for feeding materials along its inner wall along the axial direction.

[0022] The drive mechanism includes a first motor 4, a gear transmission system, a sprocket and chain transmission system, and a ring gear transmission system. The first motor 4 is fixed on the primary crushing box 2, and its output shaft is connected to one of the primary crushing rollers 201 in the primary crushing assembly. The gear transmission system is used to realize the opposite rotational transmission between the two primary crushing rollers 201 and between the two secondary crushing rollers 301. The sprocket and chain transmission system is located between the primary crushing box 2 and the secondary crushing box 3, and is used to transmit power from the primary crushing roller 201 to the secondary crushing roller 301. The ring gear transmission system includes a driven ring gear 304 fixed on the outer wall of the filter cylinder 302 and a drive gear 305 meshing with the driven ring gear 304. The drive gear 305 is rotatably connected inside the connecting box 307 fixed on the outer wall of the secondary crushing box 3. The drive gear 305 obtains power through the intermediate sprocket in the sprocket and chain transmission system, thereby driving the filter cylinder 302 to rotate.

[0023] The sprocket and chain drive system includes three sprockets, two chains, and a protective cover 306. The three sprockets are linked by the chains. The protective cover 306 is fixed between the primary crushing box 2 and the secondary crushing box 3. The first sprocket is coaxially connected to the primary crushing roller 201, the second sprocket is coaxially connected to the secondary crushing roller 301, and the third sprocket is coaxially connected to the drive gear 305.

[0024] A guide plate 5 is fixed on the inner wall of the primary crushing box 2 and below the feed inlet, and a feed hopper 6 connected to the feed inlet is fixed on the top of the primary crushing box 2.

[0025] The working principle and usage of this invention are explained in detail below: In use, the organic fertilizer raw material to be processed is fed into the feed hopper 6 fixed to the top of the primary crushing box 2. First, it is guided and spread by the guide plate 5 fixed below the feed inlet inside the box, allowing the material to fall more evenly into the space below. This design effectively improves the uniformity of feeding and reduces the localized impact of the material on subsequent components. The evenly distributed material then enters the primary crushing zone, which consists of two parallel primary crushing rollers 201. Driven by the drive mechanism, the two primary crushing rollers 201 rotate in opposite directions, performing preliminary compression and shearing crushing of the material, completing the coarse crushing operation. After preliminary crushing, the material is concentrated and guided by gravity through the guide cylinder 202 fixed to the bottom of the primary crushing box 2, and accurately falls into the secondary crushing box 3 located directly below it. This compact vertical layout and guide design achieves seamless connection between the two crushing processes, greatly optimizing the material flow path and improving space utilization and operational continuity.

[0026] When the material enters the secondary crushing chamber 3, it first falls into the secondary crushing zone, which consists of two secondary crushing rollers 301. Here, the rollers 301 also rotate in opposite directions, further refining the material from the previous stage to ensure a more significant reduction in particle size. The material, having completed secondary crushing, then falls into the filtration mechanism below, specifically a horizontally arranged and rotatable filter cylinder 302. At this point, the drive mechanism plays a crucial role, not only driving the two crushing rollers but also simultaneously driving the filter cylinder 302 to rotate slowly around its axis. The filter cylinder 302 has densely packed filter holes on its wall, and multiple feed plates 303 are fixed axially along its inner wall. During the rotation of the filter cylinder 302, the fine powder that has reached the required particle size passes through the filter holes under gravity and is collected from the outlet at the bottom of the secondary crushing chamber 3, completing the final product output. Large particles or damp, clumped materials that do not meet the standards are lifted by the rotating drum wall and continuously scooped up and raised to a certain height by the inner material-pushing plate 303 before being scattered and falling. This continuous tumbling and scattering action produces multiple beneficial effects. Firstly, it achieves dynamic screening of materials, effectively avoiding the clogging and caking problems commonly seen with wet and sticky materials on static screens, ensuring the continuous smooth operation of the screening process. Secondly, the scattered coarse materials may pass through the crushing area of ​​the secondary crushing roller 301 again during the falling process, forming an internal circulating crushing process, thereby improving crushing efficiency and finished product qualification rate without increasing additional energy consumption.

[0027] The entire device relies solely on a single motor 4 fixed to the primary crushing chamber 2 for power. Upon startup, the motor directly outputs power to one connected primary crushing roller 201, which, through a gear transmission system, drives another meshing primary crushing roller 201 to rotate synchronously in opposite directions, completing the power transmission for primary crushing. To transmit power to the next stage, the device employs a sprocket and chain transmission system. This system consists of three sprockets, two chains, and a protective cover 306 fixed between the primary and secondary crushing chambers 3. The first sprocket is coaxially connected to the primary crushing roller 201, and the second sprocket is coaxially connected to the secondary crushing roller 301. Through chain linkage, the motor's power is transmitted from the primary crushing roller 201 to the secondary crushing roller 301, driving them to rotate in opposite directions, completing the power transmission for secondary crushing. The third sprocket in the sprocket and chain transmission system is coaxially connected to a drive gear 305, which is housed within a connecting box 307 fixed to the outer wall of the secondary crushing chamber 3. When power is transmitted to the third sprocket, the drive gear 305 rotates and meshes with a large driven gear ring 304 fixed to the outer wall of the filter cylinder 302, ultimately transmitting the rotational motion to the filter cylinder 302. This achieves one machine driving three actions, demonstrating the high compactness of the structure. It simplifies the complex multi-action coordination into a reliable mechanical transmission chain, significantly reducing the manufacturing cost, operating energy consumption, and maintenance complexity of the equipment. At the same time, it ensures the synchronization of crushing and screening rhythms, improving the reliability and efficiency of the entire system.
