Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, specifically to a fertilizer caking and crushing device. Background Technology

[0002] Chemical fertilizers are fertilizers containing one or more nutrients required for crop growth, produced using chemical or physical methods. Their main characteristics are high nutrient content and rapid effectiveness, making them the most basic and important material input in agricultural production. However, some components of chemical fertilizers, such as potassium chloride and ammonium sulfate, are hygroscopic. In humid environments, these components absorb moisture from the air, causing caking on the surface or inside the fertilizer. Caking reduces the gaps between fertilizer particles, decreasing its dispersion and solubility in the soil, thus affecting crop growth and yield.

[0003] Crushing devices are generally used to disperse clumped fertilizers, but these devices lack screening equipment, so the dispersed fertilizers still remain clumped and need to be picked up manually and crushed again, which affects the crushing efficiency of clumped fertilizers. Summary of the Invention

[0004] This invention addresses the problem of the lack of screening devices in currently used fertilizer agglomeration crushing devices by providing a fertilizer agglomeration crushing device that can improve the crushing effect and efficiency of the crushing device for agglomeration fertilizer.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A fertilizer agglomeration crushing device includes an outer cylinder, an inner cylinder, and crushing components. The outer cylinder has through holes at its upper and lower ends and sealing plates at its front and rear ends. The outer cylinder is supported by support plates on its left and right sides. The inner cylinder has through holes at its upper and lower ends and sealing plates at its front and rear ends. The inner cylinder is rotatably located inside the outer cylinder and is driven to rotate by a motor. A screen is connected to the lower part of the inner cylinder. Crushing components are located on the left and right sides of the inner cylinder above the screen. The left crushing component includes multiple rotating shafts arranged from left to right. The left side of the sealing plate has arc holes corresponding to the multiple rotating shafts, with the arc holes protruding to the left. The rear end of each rotating shaft is rotatably connected to the rear sealing plate, and the front end moves through the front sealing plate. The front end of each rotating shaft extends into the corresponding arc hole, and the peripheral wall of the front end of each rotating shaft rubs against the left side of the corresponding arc hole. Multiple sets of stirring rods are provided on the rotating shaft located inside the inner cylinder.

[0007] Furthermore, the left and right portions of the outer wall of the inner cylinder respectively slide in contact with the left and right portions of the inner wall of the outer cylinder. The first sealing plate is a plate with arc surfaces on the left and right sides corresponding to the left and right inner walls of the outer cylinder and straight surfaces on the top and bottom. The second sealing plate is a plate with arc surfaces on the left and right sides corresponding to the left and right inner walls of the inner cylinder and straight surfaces on the top and bottom. The opposing sides of the two second sealing plates respectively slide in contact with the opposing sides of the two first sealing plates.

[0008] Furthermore, the middle part of the second rear sealing plate is rotatably connected to the middle part of the first rear sealing plate via a rotating rod, and the motor is fixed to the middle part of the front side of the first front sealing plate. The output end of the motor passes through the first sealing plate and connects to the middle part of the second front sealing plate.

[0009] Furthermore, the annulus containing each arc hole on the left side of the front sealing plate is concentric with the outer cylinder.

[0010] Furthermore, multiple sets of stirring rods on the same rotating shaft are spaced apart along the length of the rotating shaft. Each set of stirring rods consists of multiple stirring rod bodies. The multiple stirring rod bodies on the same set of stirring rods are arranged in a ring array along the circumference of the rotating shaft. The lower end of the circle containing the outer ends of the multiple stirring rod bodies is close to the top surface of the screen.

[0011] Furthermore, each arc hole on the left side of the front sealing plate is provided with friction texture 1, and each rotating shaft is provided with friction texture 2 at the front end of its peripheral wall. The friction texture 2 at the front end of the peripheral wall of each rotating shaft comes into frictional contact with the friction texture 1 in the corresponding arc hole.

[0012] Furthermore, a collection box is connected between the lower parts of the opposing surfaces of the two support plates, with the opening of the collection box facing upwards corresponding to the through hole one at the bottom of the outer cylinder.

[0013] The beneficial effects of this utility model through the above technical solution are as follows:

[0014] The motor drives the inner cylinder to rotate clockwise or counterclockwise, and the screen can be positioned with the left side higher than the right or vice versa. Multiple rotating shafts rotate clockwise or counterclockwise. Clumped fertilizer is fed into the inner cylinder, moves on the upper side of the screen, and is broken up by collisions with multiple stirring rods that rotate around the central axis of their respective rotating shafts. The broken fertilizer falls into the collection box as it moves along the oscillating screen. This invention can improve the crushing effect and efficiency of the crushing device for clumped fertilizer. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1-4 As shown, a fertilizer agglomeration crushing device includes an outer cylinder 1, an inner cylinder 2, and a crushing component. The outer cylinder 1 has through holes 3 at its upper and lower ends. The outer cylinder 1 is a cylindrical tube open at both ends. The through holes 3 are rectangular holes extending along the length of the outer cylinder 1, penetrating both the front and rear ends. Sealing plates 4 are provided inside both the front and rear ends of the outer cylinder 1. The left and right sides of the outer cylinder 1 are supported by support plates 5. The inner cylinder 2 has through holes 6 at its upper and lower ends. Sealing plates 7 are provided inside both the front and rear ends of the inner cylinder 2. The inner cylinder 2 is a cylindrical tube open at both ends. The through holes 6 are rectangular holes extending along the length of the inner cylinder 2, penetrating both the front and rear ends of the inner cylinder 2. The inner cylinder 2 is rotatably mounted inside the outer cylinder 1 and is electrically controlled. The machine 8 is driven to rotate, and a screen 9 is connected to the lower part of the inner cylinder 2. The inner cylinder 2 on the upper side of the screen 9 is equipped with crushing parts on both the left and right sides. The two crushing parts are symmetrical. The crushing part on the left side includes multiple rotating shafts 10. The rotating shafts 10 are round rods. The multiple rotating shafts 10 are arranged from left to right. The left side of the front sealing plate 1 4 is provided with an arc hole 16 corresponding to the multiple rotating shafts 10. The arc hole 16 protrudes to the left. The rear end of each rotating shaft 10 is rotatably connected to the rear sealing plate 2 7, and the front end moves through the front sealing plate 2 7. The front end of each rotating shaft 10 extends into the corresponding arc hole 16. The peripheral wall of the front end of each rotating shaft 10 rubs against the left side of the corresponding arc hole 16. Multiple sets of stirring rods are provided on the rotating shafts 10 located in the inner cylinder 2.

[0022] The outer left and right parts of the inner cylinder 2 slide in contact with the inner left and right parts of the outer cylinder 1, respectively. The upper and lower ends of the inner cylinder 2 extend out of the upper and lower through holes 3, respectively. The sealing plate 4 is a plate with arc surfaces on the left and right sides corresponding to the left and right inner walls of the outer cylinder 1 and straight surfaces on the top and bottom. The sealing plate 7 is a plate with arc surfaces on the left and right sides corresponding to the left and right inner walls of the inner cylinder 2 and straight surfaces on the top and bottom. The opposite sides of the two sealing plates 7 slide in contact with the opposite sides of the two sealing plates 4, respectively.

[0023] The middle part of the rear sealing plate 2 7 is rotatably connected to the middle part of the rear sealing plate 1 4 via the rotating rod 17. The motor 8 is fixed to the middle part of the front side of the front sealing plate 1 4. The output end of the motor 8 passes through the sealing plate 1 4 and connects to the middle part of the front sealing plate 2 7. The motor 8 selected in this utility model is model F5D200-24GU-18S. The output shaft of this model of motor can rotate forward or backward.

[0024] The ring containing each arc hole 16 on the left side of the front sealing plate 4 is concentric with the outer cylinder 1.

[0025] Multiple sets of stirring rods on the same rotating shaft 10 are spaced apart along the length of the rotating shaft 10. Each set of stirring rods consists of multiple stirring rod bodies 11. The stirring rod body 11 is a round rod. Multiple stirring rod bodies 11 on the same set of stirring rods are arranged in a ring array along the peripheral wall of the rotating shaft 10. The lower end of the circle containing the outer ends of the multiple stirring rod bodies 11 is close to the top surface of the screen 9.

[0026] Each arc hole 16 on the left side of the front sealing plate 4 is provided with friction texture 12, and each rotating shaft 10 is provided with friction texture 2 13 at the front end of the peripheral wall. The friction texture 2 13 at the front end of the peripheral wall of each rotating shaft 10 is in frictional contact with the friction texture 12 in the corresponding arc hole 16. The friction texture 12 and friction texture 2 13 are both raised grid-like patterns.

[0027] In use, motor 8 starts and drives inner cylinder 2 to rotate clockwise (the clockwise rotation of inner cylinder 2 is...). Figure 2 From the perspective of [the inner cylinder 2], the inner cylinder 2 drives the screen 9 to rotate clockwise, with the screen 9 in a state where the left side is higher than the right. Multiple rotating shafts 10 on the left side move with the inner cylinder 2. Because the front end of each rotating shaft 10 rubs against the left side of the corresponding arc hole 16, each rotating shaft 10 rotates counterclockwise around its own central axis. Multiple sets of stirring rods rotate counterclockwise with the rotating shaft 10. Similarly, multiple rotating shafts 10 on the right side rotate counterclockwise, and multiple sets of stirring rods rotate counterclockwise with the rotating shaft 10. When the front end of the rotating shaft 10 on the left side approaches the upper end of the corresponding arc hole 16, the motor... Motor 8 drives the inner cylinder 2 to rotate counterclockwise, causing the screen 9 to be in a state of left-low-right-high. During the counterclockwise rotation of the inner cylinder 2, multiple rotating shafts 10 drive the stirring rod 11 to rotate clockwise until the front end of the multiple rotating shafts 10 on the left side approaches the lower end of the corresponding arc hole 16. Then, motor 8 drives the inner cylinder 2 to rotate clockwise again. Therefore, during the clockwise and counterclockwise rotation of the inner cylinder 2 driven by motor 8 of this utility model, the screen 9 can be in a state of left-high-right-low or left-low-right-high, and the multiple rotating shafts 10 can rotate in a state of counterclockwise or clockwise.

[0028] The clumped fertilizer is fed into the inner cylinder 2 through the upper through-hole 6. When the inner cylinder 2 rotates clockwise, the clumped fertilizer moves from left to right on the screen 9 and is broken by collisions with multiple stirring rods 11 that rotate counterclockwise around the central axis of their respective rotating shafts 10. When the inner cylinder 2 rotates counterclockwise, the clumped fertilizer moves from right to left on the screen 9 and is broken by collisions with multiple stirring rods 11 that rotate clockwise around the central axis of their respective rotating shafts 10. As the broken fertilizer moves along the oscillating screen 9, it can move downward through the screen holes of the screen 9 and fall into the collection box 14 through the lower through-hole 6 and the lower through-hole 3.

[0029] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
