Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, specifically to a fertilizer raw material crushing device for fertilizer production. Background Technology

[0002] Chemical fertilizers, or simply fertilizers, are fertilizers containing one or more nutrients needed for crop growth, produced using chemical and physical methods. Also known as inorganic fertilizers, they include nitrogen fertilizers, phosphate fertilizers, potassium fertilizers, micronutrient fertilizers, and compound fertilizers. They share some common characteristics: simple composition and high nutrient content; rapid and potent effects; some fertilizers exhibit acid-base reactions; generally, they do not contain organic matter and do not improve soil structure. Chemical fertilizers come in many types, with significant differences in properties and application methods. The processing of chemical fertilizers requires the crushing of raw materials.

[0003] As disclosed in Chinese Patent CN216856975U, a raw material crushing device for fertilizer production includes a machine body. A cover is slidably fitted onto the top of the machine body, and a motor is mounted on the cover. A feed inlet is located on the cover, and a discharge outlet is fixedly connected to the bottom of the machine body. A fixing ring is fixedly connected to the outside of the machine body, and a support leg is slidably connected inside the fixing ring. A collar is fixedly connected to the top of the support leg, and a machine body is slidably connected inside the collar. A first spring is sleeved on the outside of the support leg. This invention utilizes a guide seat on the grinding head, which is sleeved with a rotating shaft. A positioning pin, which extends and retracts via a second spring, is installed inside the guide seat. The positioning pin engages with a matching positioning groove on the rotating shaft, enabling quick assembly between the guide seat and the rotating shaft. This also facilitates the rapid removal and replacement of damaged grinding heads later.

[0004] However, the crushing effect of the raw material crushing device used for fertilizer production is incomplete and unsatisfactory, which will affect the subsequent mixing of materials and reduce the processing rate. In addition, the existing crushing device for fertilizer raw materials does not have a screening mechanism. After crushing the fertilizer, the lack of a screening mechanism to separate large particles of raw materials for secondary crushing affects the crushing efficiency.

[0005] Therefore, a fertilizer raw material crushing device for fertilizer production is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a fertilizer raw material crushing device for fertilizer production in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A fertilizer raw material crushing device for fertilizer production includes a crushing box and a protective plate. The protective plate is snapped onto the upper surface of the crushing box. A feeding chute is provided on one side of the upper surface of the protective plate. A screening component is provided on the lower side of the inside of the crushing box, and a crushing component is provided on the upper part of the inside of the crushing box.

[0009] Furthermore, the screening assembly includes trapezoidal grooves extending through both sides of the lower part of the outer surface of the crushing box. A screening seat is fixedly installed on the bottom surface of the crushing box. The screening seat is trapezoidal in shape, and screening holes are extending through the inclined surfaces at both ends of the screening seat. A partition is fixedly connected to the bottom surface of the screening seat. A discharge chute extends through both ends of the lower part of the other side of the outer surface of the crushing box, and a connecting frame is fixedly installed on the inner wall of the discharge chute.

[0010] Furthermore, the crushing assembly includes a fixed plate fixedly connected to one side of the outer surface of the crushing chamber. A drive motor is fixedly mounted on the upper surface of the fixed plate, and a transmission shaft is connected to the output end of the drive motor. A reducer is fixedly mounted on one side of the upper surface of the fixed plate, and a first connecting shaft is connected to the output end of the reducer. A first crushing blade is fixedly mounted on the outer surface of the first connecting shaft. A first gear is fixedly connected to one end of the first connecting shaft. A second gear meshes with one side of the outer surface of the first gear. A second connecting shaft is fixedly connected to one end of the second gear, and a second crushing blade is fixedly mounted on the outer surface of the second connecting shaft.

[0011] Furthermore, a base plate is fixedly connected to the bottom surface of the crushing box, and a number of moving wheels are provided on the bottom surface of the base plate, which are symmetrically distributed at the four corners of the bottom surface of the base plate.

[0012] Furthermore, a guide plate is fixedly connected to the upper part of the inner wall of the crushing box. The upper part of the outer surface of the guide plate is arc-shaped, and the guide plates are symmetrically distributed on both sides of the upper part of the inner wall of the crushing box.

[0013] Furthermore, one end of the drive shaft is connected to the input end of the reducer, one end of the second connecting shaft is rotatably connected to one side of the inner wall of the crushing box, and a fixing frame is fixedly installed on the other side of the outer surface of the crushing box.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention, through the inclusion of a screening component, allows fertilizer raw materials, after being crushed, to fall under their own weight onto the upper surface of a trapezoidal screening base, and then slide down the inclined surfaces on both sides. The finely crushed fertilizer raw materials fall through the screening holes into the screening base, while the larger crushed materials slide down the inclined surfaces of the screening base to the discharge chute, where they are collected at the connecting frame and then re-input into the crushing chamber for further crushing. The fine fertilizer raw materials filtered through the screening holes are collected through the trapezoidal grooves running along both sides, thus improving the efficiency of fertilizer production. The crushing quality and effect of the material are improved, allowing fertilizer raw materials that do not meet the crushing standards to be crushed again. By setting up a crushing assembly, the first connecting shaft in the crushing assembly drives the first gear to rotate, which in turn drives the second gear to rotate, thereby driving the second connecting shaft to rotate. This achieves the opposite rotation of the first and second connecting shafts, which in turn causes the first and second crushing blades to rotate in opposite directions. The fertilizer raw materials that fall between the two sets of blades are effectively crushed. The power of the drive shaft is controlled and adjusted by a reducer to improve the crushing efficiency.

[0026] like Figure 1-4 As shown, a fertilizer raw material crushing device for fertilizer production includes a crushing box 1 and a protective plate 2. The protective plate 2 is snapped onto the upper surface of the crushing box 1. A feeding chute 3 is provided on one side of the upper surface of the protective plate 2. A screening component 8 is provided on the lower side of the inside of the crushing box 1, and a crushing component 6 is provided on the upper part of the inside of the crushing box 1. Fertilizer raw materials are fed into the crushing box 1 through the feeding chute 3. The crushing component 6 is operated to crush the fertilizer raw materials, and the screening component 8 is operated to screen the crushed fertilizer raw materials.

[0027] The screening component 8 includes a trapezoidal groove 801 extending through both sides of the lower part of the outer surface of the crushing box 1. A screening seat 802 is fixedly installed on the bottom surface of the inner side of the crushing box 1. The screening seat 802 is trapezoidal, and screening holes 803 are penetrating through the inclined surfaces at both ends of the screening seat 802. A partition plate 804 is fixedly connected to the bottom surface of the screening seat 802. A discharge chute 805 extends through both ends of the lower part of the other side of the outer surface of the crushing box 1, and a connecting frame 806 is fixedly installed on the inner wall of the discharge chute 805. When the crushed fertilizer raw materials fall onto the upper surface of the screening seat 802 and slide to both sides, the finely crushed fertilizer raw materials fall into the screening seat 802 through the screening holes 803 and are collected from the trapezoidal groove 801. The larger crushed fertilizer raw materials slide into the discharge chute 805 and are collected at the connecting frame 806 for further crushing.

[0028] The crushing assembly 6 includes a fixing plate 601 fixedly connected to one side of the outer surface of the crushing chamber 1. A drive motor 602 is fixedly mounted on the upper surface of the fixing plate 601. The output end of the drive motor 602 is connected to a transmission shaft 603. A reducer 604 is fixedly mounted on one side of the upper surface of the fixing plate 601. The output end of the reducer 604 is connected to a first connecting shaft 605. A first crushing blade 606 is fixedly mounted on the outer surface of the first connecting shaft 605. A first gear 607 is fixedly connected to one end of the first connecting shaft 605. A second gear 608 meshes with one side of the outer surface of the first gear 607. A second connecting shaft 608 is fixedly connected to one end of the second gear 608. Connecting shaft 609, with a second crushing blade 610 fixedly mounted on its outer surface; when the power to drive motor 602 is turned on, the output end of drive motor 602 drives transmission shaft 603 to rotate, transmitting power to reducer 604 and outputting to connecting shaft 605. The rotation of connecting shaft 605 drives the first crushing blade 606 to rotate, and simultaneously drives gear 607 to rotate, which in turn drives gear 608 to rotate, thus enabling connecting shaft 609 to drive the second crushing blade 610 to rotate. The first crushing blade 606 and the second crushing blade 610 rotate in opposite directions to crush the falling fertilizer raw materials.

[0029] A base plate 4 is fixedly connected to the bottom surface of the crushing box 1. Several moving wheels 5 are provided on the bottom surface of the base plate 4. The moving wheels 5 are symmetrically distributed at the four corners of the bottom surface of the base plate 4. The presence of several moving wheels 5 on the bottom surface of the base plate 4 facilitates the movement of the crushing box 1 by rotating the moving wheels 5, making it convenient to crush fertilizer raw materials at any position.

[0030] A guide plate 7 is fixedly connected to the upper part of the inner wall of the crushing box 1. The upper part of the outer surface of the guide plate 7 is arc-shaped, and the guide plates 7 are symmetrically distributed on both sides of the upper part of the inner wall of the crushing box 1. The guide plates 7 are distributed on both sides of the inner wall of the crushing box 1, which can guide the falling fertilizer raw materials, so that the falling path of the fertilizer raw materials is located in the middle of the two sets of crushing blades, so that the fertilizer raw materials are better crushed.

[0031] One end of the drive shaft 603 is connected to the input end of the reducer 604, and one end of the second connecting shaft 609 is rotatably connected to one side of the inner wall of the crushing box 1. A fixing frame 611 is fixedly installed on the other side of the outer surface of the crushing box 1. The fixing frame 611 protects the rotation between the first gear 607 and the second gear 608 to prevent external objects from affecting its normal operation.

[0032] In summary, this fertilizer raw material crushing device for fertilizer production feeds fertilizer raw materials into the crushing box 1 through the feed chute 3 on the upper surface of the protective plate 2. When the power to the drive motor 602 is turned on, the output shaft of the drive motor 602 drives the transmission shaft 603 to rotate. The transmission shaft 603 then transmits power to the reducer 604, which in turn drives the first connecting shaft 605 to rotate. This, in turn, drives the first crushing blade 606 and the first gear 607 to rotate. The first gear 607 then drives the second gear 608 to rotate, thus enabling the second connecting shaft 609 to drive the second crushing blade. The blade 610 rotates, and the first crushing blade 606 and the second crushing blade 610 rotate in opposite directions to crush the falling fertilizer raw materials. The crushed fertilizer raw materials fall onto the upper surface of the screening seat 802 and slide down the inclined surfaces on both sides. The finely crushed fertilizer raw materials fall into the screening seat 802 through the screening holes 803. The larger crushed fertilizer raw materials continue to slide down the inclined surface of the screening seat 802 to the discharge trough 805, where they are collected and then put back into the crushing box 1 for crushing. The finely crushed fertilizer raw materials are collected from the trapezoidal trough 801.
