Description

Technical Field

[0001] This utility model belongs to the field of fertilizer processing technology, and in particular to a crushing device for raw materials in the production of water-soluble fertilizer. Background Technology

[0002] Water-soluble fertilizer is a compound fertilizer that can be completely dissolved in water. During the production process of water-soluble fertilizer, a crushing device is required to crush the raw materials. Existing crushing devices usually use a rotating cutting tool to crush the raw materials, which can easily lead to insufficient contact between the raw materials and the cutting tool, thus reducing the crushing effect of the crushing device.

[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN220919337U) entitled "A Crushing Device for Raw Materials in Water-Soluble Fertilizer Production." This device includes a support frame, a crushing chamber fixedly connected to the inner side of the support frame, a base fixedly connected to the upper end of the crushing chamber, a hydraulic rod fixedly connected to the upper end of the base, and a pressing mechanism at the upper end of the hydraulic rod. The pressing mechanism includes a connecting rod fixedly connected to the upper end of the hydraulic rod, a first connecting block fixedly connected to the lower end of the connecting rod near the front of the hydraulic rod, and a second connecting block fixedly connected to the front end of the first connecting block via a rotating shaft. This device, through the second connecting block driving a gravity block to press down on the main gravity block under its own weight, crushes the hardened raw materials first, and then filters the finer materials through a filter screen. This not only protects the blades to a certain extent but also improves the crushing effect and quality. However, this device does not consider the possibility of insufficient contact between the crushing blades and the raw materials in water-soluble fertilizer production, reducing the crushing effect of the device on these materials. Utility Model Content

[0004] The purpose of this invention is to provide a crushing device for raw materials used in the production of water-soluble fertilizers, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crushing device for raw materials used in water-soluble fertilizer production, comprising:

[0006] A crushing box for crushing raw materials for water-soluble fertilizer production. The inner cavity of the crushing box is equipped with a rotating rod, and several crushing cutters for crushing raw materials for water-soluble fertilizer production are connected to the side of the rotating rod.

[0007] A filter box for filtering raw materials used in water-soluble fertilizer production has a filter assembly inside. The filter assembly includes a filter frame and a filter screen for filtering raw materials used in water-soluble fertilizer production. The inner wall of the filter frame is connected to the filter screen. Four L-shaped connecting plates are connected to the bottom of the filter frame. Two connecting plates are connected to hollow sliding plates on adjacent sides. A slide frame is fitted onto the side of the slide frame. Fixed bearings are embedded and fixedly connected to the two outer walls of the slide frame. Moving rods are interference-fitted to the inner rings of the four fixed bearings. Rotating plates are connected to the two end faces of the moving rods. Rotating columns are connected to the sides of the rotating plates.

[0008] Preferably, the bottom surface of the crushing box is connected to the top surface of the filter box by bolts, the inner top wall of the crushing box is rotatably connected to the rotating rod, and the two outer side walls of the filter box are rotatably connected to the two rotating columns.

[0009] Preferably, the inner walls of the two slide plates are movably connected to the moving rod, the inner side wall of the filter box is in sliding friction contact with the filter frame and the four connecting plates respectively, and the top surface of the rotating rod is connected to the output shaft of the rotary motor through a coupling.

[0010] Preferably, the fixed end of the rotary motor is connected to the crushing box by bolts, and the output shaft of the drive motor is connected to one end face of the rotating column by a coupling. The fixed end of the drive motor is connected to the filter box by bolts.

[0011] Preferably, a feeding assembly is provided on the top of the crushing box. The feeding assembly includes a feeding frame and a guide plate, and the outer periphery of the feeding frame is connected to the crushing box.

[0012] Preferably, the bottom surface of the feed rack is connected to two fixing blocks, and the two fixing blocks are rotatably connected to the guide plate by pins on adjacent sides.

[0013] Preferably, a through groove is provided on the side of the guide plate, and a movable rod is movably connected to the inner wall of the through groove of the guide plate.

[0014] Preferably, the two ends of the movable rod are connected to connecting blocks, the top surface of the connecting blocks is connected to the moving end of the electric push rod, and the fixed ends of the two electric push rods are embedded in the top wall of the crushing box.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This water-soluble fertilizer production raw material crushing device crushes the water-soluble fertilizer production raw materials introduced into the crushing box through several crushing cutters. During the crushing process, insufficient contact between the water-soluble fertilizer production raw materials and the crushing cutters is very likely to occur, reducing the crushing and processing effect of the crushing device on the water-soluble fertilizer production raw materials. When the two rotating columns rotate, the rotating columns and moving rods set on both sides of the rotating plate are staggered. During the transmission process, the moving rods move along the inner cavity of the sliding plate. Under the connection provided by the four connecting plates, the filter frame drives the filter screen to move vertically, providing a bumping effect on the water-soluble fertilizer production raw materials at the top of the filter screen, so that the water-soluble fertilizer production raw materials make full contact with the crushing cutters, thereby enhancing the crushing and processing effect of the crushing device on the water-soluble fertilizer production raw materials.

[0017] The raw material crushing device for water-soluble fertilizer production is equipped with four fixed bearings to fix the rotation position of the moving rod. At the same time, the four fixed bearings provide a connecting function, so that when one moving rod moves along the inner cavity of the slide plate, it drives two slide frames to move laterally and reciprocally along the path of the slide plate, thereby improving the structural stability of the device components.

[0018] This water-soluble fertilizer production raw material crushing device facilitates the introduction of water-soluble fertilizer production raw materials into the crushing box via a feeding assembly. The raw materials are introduced into the crushing box through a feeding frame, and a guide plate distributes the raw materials inside the crushing box to prevent them from accumulating in a fixed position. Two electric push rods provide power, and their moving ends move synchronously in the same direction. During the movement of the moving ends of the electric push rods, the connecting block moves vertically, causing the movable frame to move vertically along the inner cavity of the guide plate. During the transmission process, the guide plate provides a bumping effect on the introduced water-soluble fertilizer production raw materials. Under certain conditions, the position of the water-soluble fertilizer production raw materials introduced into the crushing box can be controlled to ensure that the crushing device fully crushes and processes the raw materials.

[0028] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0029] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0030] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0031] To address the issue of insufficient contact between the raw materials and the crushing blades in water-soluble fertilizer production raw material crushing equipment, which easily leads to reduced crushing efficiency, please refer to [link to relevant documentation]. Figures 1 to 6 The structure of the device body includes:

[0032] A crushing box 1 for crushing raw materials for water-soluble fertilizer production. The inner cavity of the crushing box 1 is equipped with a rotating rod 2, and the side of the rotating rod 2 is connected to several crushing cutters 3 for crushing raw materials for water-soluble fertilizer production.

[0033] A filter box 4 is used for filtering raw materials for water-soluble fertilizer production. The filter box 4 has a filter assembly 5 inside. The filter assembly 5 includes a filter frame 6 and a filter screen 7 for filtering raw materials for water-soluble fertilizer production. The inner side wall of the filter frame 6 is connected to the filter screen 7. The bottom surface of the filter frame 6 is connected to four L-shaped connecting plates 8. Two connecting plates 8 are connected to hollow sliding plates 9 on adjacent sides. The sliding plates 9 are fitted with slide frames 10 on the sides. Fixed bearings 11 are embedded and fixedly connected to the two outer side walls of the slide frames 10. The inner rings of the four fixed bearings 11 are press-fitted with moving rods 12. The two ends of the moving rods 12 are connected to rotating plates 13. The sides of the rotating plates 13 are connected to rotating columns 14.

[0034] In this embodiment, the rotating rod 2 rotates, and several crushing cutters 3 rotate around the rotating rod 2 as the axis, so that the crushing cutters 3 provide crushing processing for the water-soluble fertilizer production raw materials inside the crushing box 1. The bottom surface of the lowest crushing cutter 3 is flush with the bottom surface of the crushing box 1. The rotating columns 14 and moving rods 12 on both sides of the rotating plate 13 are staggered. When the two rotating columns 14 rotate, the rotating plate 13 rotates around the rotating columns 14 as the axis. During the transmission process, the moving rods 12 move in a circle around the two rotating columns 14 as the axis, so that the moving rods 12 move along the inner cavity of the two sliding plates 9, realizing the vertical reciprocating movement of the two sliding plates 9. Under the connection provided by the four connecting plates 8, the filter frame 6 drives the filter screen 7 to move vertically. The filter 6 moves back and forth, causing the water-soluble fertilizer raw material at the top of the filter screen 7 to be shaken. This allows the partially crushed raw material to come into full contact with the crushing cutter 3, enhancing the crushing effect of the crushing device. When the filter frame 6 moves to the top, its top surface is flush with the top surface of the filter box 4, allowing the water-soluble fertilizer raw material to be shaken by the filter screen 7 and fully cut by the crushing cutter 3. At the same time, as the moving rod 12 moves along the inner cavity of the two slide plates 9, it drives the two slide frames 10 to slide down along the path of the two slide plates 9. During the transmission process, the vertical reciprocating stability of the filter frame 6 and the filter screen 7 is enhanced. The crushed water-soluble fertilizer raw material flows through the mesh of the filter screen 7 to the inner bottom wall of the filter box 4.

[0035] Specifically, the bottom surface of the crushing box 1 is connected to the top surface of the filter box 4 by bolts, the inner top wall of the crushing box 1 is rotatably connected to the rotating rod 2, the two outer side walls of the filter box 4 are rotatably connected to the two rotating columns 14, the inner walls of the two sliding plates 9 are movably connected to the moving rod 12, and the inner side walls of the filter box 4 are in sliding friction contact with the filter frame 6 and the four connecting plates 8 respectively.

[0036] In this embodiment, the crushing box 1 is fixed to the top of the filter box 4 by bolts, and the crushing box 1 is connected to the filter box 4, so that the water-soluble fertilizer production raw materials processed inside the crushing box 1 are introduced into the filter box 4. The top of the rotating rod 2 penetrates the inner top wall of the crushing box 1, and the rotating rod 2 is rotatably connected to the crushing box 1. The filter box 4 provides a fixing function for the rotation of the two rotating columns 14. The four connecting plates 8 are divided into two groups, and the inner side walls of the two groups of connecting plates 8 are centrifugally arranged. The centrifugally arranged side of the two groups of connecting plates 8 is slidably connected to the inner side wall of the filter box 4, so that the filter box 4 fixes the vertical movement path of the filter frame 6 and the four connecting plates 8.

[0037] Specifically, the top surface of the rotating rod 2 is connected to the output shaft of the rotating motor 15 via a coupling, and the fixed end of the rotating motor 15 is connected to the crushing box 1 via bolts. The end face of one of the rotating columns 14 is connected to the output shaft of the drive motor 16 via a coupling, and the fixed end of the drive motor 16 is connected to the filter box 4 via bolts.

[0038] In this embodiment, the rotary motor 15 and the drive motor 16 provide power so that the output shaft of the rotary motor 15 rotates and drives the rotating rod 2 to rotate. During the rotation of the rotating rod 2, the crushing and cutting blades 3 crush and cut the raw materials for water-soluble fertilizer production. During the rotation of the output shaft of the drive motor 16, one of the rotating columns 14 rotates. During the transmission process, the filter frame 6 drives the filter screen 7 to move vertically back and forth.

[0039] Specifically, a feeding assembly 17 is provided on the top of the crushing box 1. The feeding assembly 17 includes a feeding frame 18 and a guide plate 20. The outer periphery of the feeding frame 18 is connected to the crushing box 1. Two fixing blocks 19 are connected to the bottom surface of the feeding frame 18. The two fixing blocks 19 are rotatably connected to the guide plate 20 through pins. A through groove is opened on the side of the guide plate 20. A movable rod 21 is movably connected to the inner wall of the through groove of the guide plate 20. Connecting blocks 22 are connected to both ends of the movable rod 21. The moving end of the electric push rod 23 is connected to the top surface of the connecting block 22. The fixed ends of the two electric push rods 23 are embedded in the top wall of the crushing box 1. A discharge port 24 is installed on the side of the filter box 4.

[0040] In this embodiment, the water-soluble fertilizer production raw materials to be crushed are introduced into the crushing box 1 through the feeding rack 18. Two through slots are opened on the top surface of the crushing box 1. The inner walls of the two through slots of the crushing box 1 are respectively connected to the fixed ends of two electric push rods 23 by bolts, so that the two electric push rods 23 provide power and the moving ends of the two electric push rods 23 move synchronously in the same direction. During the movement of the moving ends of the electric push rods 23, the connecting block 22 moves vertically, which in turn drives the movable rod 21 to move along the inner wall of the through slot of the guide plate 20, so that the guide plate 20 and the two fixed blocks 19 rotate relative to each other, so that the guide plate 20 shakes the water-soluble fertilizer production raw materials to be crushed, preventing the water-soluble fertilizer production raw materials introduced into the crushing box 1 from always being in a fixed position, and distributing the water-soluble fertilizer production raw materials introduced into the crushing box 1, so as to realize the full crushing of the water-soluble fertilizer production raw materials by the crushing device.

[0041] The rotary motor 15, drive motor 16, and electric push rod 23 are all existing technologies. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0042] Working principle

[0043] When using this water-soluble fertilizer production raw material crushing device, the user introduces the water-soluble fertilizer production raw material to be crushed into the crushing box 1 through the feeding rack 18, starts the two electric push rods 23, and drives the connecting block 22 to move vertically during the movement of the moving ends of the two electric push rods 23, so that the movable rod 21 moves on the inner wall of the through groove of the guide plate 20, so that the guide plate 20 shakes the water-soluble fertilizer production raw material and distributes the water-soluble fertilizer production raw material introduced into the crushing box 1.

[0044] Start the rotary motor 15. During the rotation of the output shaft of the rotary motor 15, the rotating rod 2 will rotate, causing several crushing cutters 3 to rotate around the rotating rod 2 as the axis, and crushing and processing the water-soluble fertilizer production raw materials inside the crushing box 1.

[0045] When the drive motor 16 is started, the output shaft of the drive motor 16 rotates, causing one of the rotating columns 14 to rotate. With the connection of the rotating plate 13, the moving rod 12 moves along the inner cavity of the slide plate 9, and the slide 10 moves down along the path of the slide plate 9, causing the two slide plates 9 to move vertically back and forth. With the connection of the four connecting plates 8, the filter frame 6 drives the filter screen 7 to move vertically back and forth, causing the water-soluble fertilizer production raw material at the top of the filter screen 7 to be shaken, so that the crushing device can fully crush and process the water-soluble fertilizer production raw material.
