Description

Technical Field

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

[0002] Organic fertilizer refers to fertilizer processed from organic matter. The main raw materials include plant and animal excrement, which are produced through processes such as crushing, mixing, granulation, and drying. The organic matter in organic fertilizer decomposes in the soil, improving soil structure and increasing its water and fertilizer retention capacity. The decomposition process of organic matter in the soil is prolonged, ensuring a continuous supply of nutrients for plant growth, potentially playing a role throughout the growing season. The aforementioned crushing process is carried out using crushing devices, with roller crushers being a commonly used type. These devices quickly crush materials into the desired granular shape through extrusion and crushing, offering high processing efficiency. However, existing roller crushers also have certain drawbacks. Specifically, the feed inlet is located at a high position, and materials are generally manually shoveled into the inlet for crushing. The high position of the feed inlet results in high labor intensity for workers and easily generates dust, thus polluting the surrounding air environment. Therefore, improvements are needed.

[0017] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0018] like Figures 1 to 4As shown, this utility model embodiment provides a crushing device for organic fertilizer production, including a frame 1 and a crushing mechanism 2 mounted on the frame 1. A base plate 3 is provided at the bottom of the frame 1, and a screw feeding mechanism 4 is mounted on the base plate 3. The screw feeding mechanism 4 includes a first housing 41 and a feeding screw rotatably connected within the first housing 41. The first housing 41 has a circular cross-section. The feeding screw specifically includes a rotating shaft 42 and screw blades 43 fixed to the outside of the rotating shaft 42. The upper and lower ends of the rotating shaft 42 are respectively connected to bearings at the upper and lower ends of the first housing 41. A gap is provided between the outer side of the screw blades 43 and the inner side of the first housing 41, allowing the feeding screw to rotate freely within the first housing 41 and convey material upwards during rotation. The feeding screw is connected to a feeding motor 44, which drives the feeding screw to rotate. A first feeding port 45 is provided at the lower end of the first housing 41, and a discharge port is provided at the upper end of the first housing 41. One end of the first housing 41 outside the discharge port is connected to a discharge pipe 46. The crushing mechanism is a conventional double-roller crusher, comprising a crushing motor 21 fixed on a frame 1 and a second housing 22. Two crushing rollers 23 are rotatably connected to the second housing 22. The crushing motor 21 is connected to the crushing rollers 23 and drives them to rotate, thereby crushing the material. Specifically, the crushing motor 21 is fixedly connected to one of the crushing rollers 23 via a coupling 25, and the two crushing rollers 23 are connected by two gears 26. The lower side of the second housing 22 is fixedly connected to a discharge pipe 24, through which the crushed material is discharged. Additionally, a screen is typically installed on the upper side of the discharge pipe 24, allowing only crushed material smaller than the mesh size to fall through. A top cover 5 is located at the upper end of the second housing 22, with a through hole 51 corresponding to the discharge pipe 46. The other end of the discharge pipe 46 is positioned within the through hole 51, allowing the material discharged from the outlet to be fed onto the crushing rollers 23 below the top cover 5 for crushing. The aforementioned feeding motor 44 and crushing motor 21 are both connected to the control box 8 mounted on the frame 1. The control box 8 obtains working power from the field through a power line. It contains circuits and start / stop switches for controlling the operation of the feeding motor 44 and crushing motor 21, thereby controlling the operation of the feeding motor 44 and crushing motor 21.

[0019] To disperse the material fed from the discharge pipe 46, a distribution plate 6 is fixed inside the top cover 5 on the lower side of 51. The distribution plates 6 are spaced apart on the upper side of the crushing roller 23, and are herringbone in shape with their inner ends inclined downwards. After the material falls onto the distribution plate 6, it slides downwards and to the sides, thus dispersing more evenly onto the crushing roller 23, avoiding congestion in the middle and improving the crushing effect. To facilitate the fixing of the distribution plate 6, multiple support plates 7 are fixed between the lower side of the distribution plate 6 and the top cover 5. The support plates 7 are preferably triangular in shape, and to reduce the weight of the support plates 7, the middle part of the support plates 7 is preferably hollowed out.

[0020] To facilitate the connection between the feeding motor 44 and the rotating shaft 42, a first clearance hole 9 is provided on the base plate 3 at a position corresponding to the rotating shaft 42. The lower end of the rotating shaft 42 passes through the first housing 41 and the first clearance hole. A driven wheel 10 is fixed to the lower end of the rotating shaft 42. The feeding motor 44 is fixed on the upper side of the base plate 3. A second clearance hole 11 is provided on the base plate 3 at a position corresponding to the rotor 441 of the feeding motor 44. The rotor 441 of the feeding motor 44 passes through the second clearance hole 11 and is fixedly connected to the driving wheel 12. The driving wheel 12 and the driven wheel 10 are connected by a drive belt 13. In addition, the lower surfaces of the driving wheel 12 and the driven wheel 10 should be above the lower end of the frame 1 to avoid contact with the ground.

[0021] To facilitate the feeding of materials into the first feeding port 45, it is preferable to fix a feeding hopper 14 on the first housing 41 outside the first feeding port 45.

[0022] Since the screw feeding mechanism 4 may not be able to meet the transportation needs of all materials, it is preferable to set a second feeding port 15 at the end of the top cover 5 away from the screw feeding mechanism 4, and to provide a top cover 16 on the outside of the second feeding port 15. For materials that cannot be transported by the screw feeding mechanism 4, the top cover 16 can be opened directly and fed into the second feeding port 15.

[0023] The above description is merely a preferred embodiment of this utility model. It should be noted that for those skilled in the art, other parts not specifically described are existing technology or common knowledge. Several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
