Description

Technical Field

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

[0002] In today's agricultural sector, organic fertilizers, rich in various organic substances and nutrients, are increasingly becoming an indispensable input in agricultural production due to their numerous advantages, including effectively improving soil structure, enhancing soil fertility, promoting crop growth, and being environmentally friendly. With the acceleration of agricultural modernization and people's pursuit of green and ecological agriculture, the market demand for organic fertilizers is showing a continuous growth trend. This has prompted organic fertilizer manufacturers to continuously expand their production scale and improve production efficiency to meet market supply demands. In the production and processing of organic fertilizers, the crushing process is crucial. The purpose of crushing is to break the raw materials into suitable particle sizes, which not only facilitates subsequent mixing and granulation processes but also improves the quality and uniformity of the organic fertilizer product.

[0003] Existing crushing devices are not suitable for screening the crushed materials, resulting in uneven particle size of the crushed organic fertilizer materials and a large number of non-compliant coarse particles. These coarse particles will affect the overall quality of the product in subsequent production processes. At the same time, existing technologies are not suitable for secondary crushing of non-compliant materials, resulting in low crushing efficiency.

[0004] Therefore, we propose a crushing device for organic fertilizer production and processing to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figures 1-6 As shown in the figure, an embodiment of the present invention discloses a crushing device for organic fertilizer production and processing, including a crushing box 1. Two crushing rollers 2 are symmetrically and rotatably connected inside the crushing box 1. The shaft ends of the two crushing rollers 2 on the same side penetrate the side wall of the crushing box 1 and are fixedly connected to meshing gears 3. A support seat 4 is fixedly connected to the side wall of the crushing box 1 away from the gears 3. A first motor 5 is fixedly connected to the upper end of the support seat 4. The drive end of the first motor 5 is fixedly connected to its shaft end near the crushing rollers 2. A guide box 6 is fixedly connected to the lower end of the crushing box 1. A filtering and re-crushing mechanism 7 is provided on the lower side of the guide box 6. The first motor 5 drives the crushing rollers 2 connected to it to rotate, and under the transmission of the gears 3, the two crushing rollers 2 rotate synchronously, thereby crushing the organic fertilizer material entering the crushing box 1. The guide box 6 facilitates the guidance and conveying of the material after the first crushing process to the filtering and re-crushing mechanism 7, thus facilitating the filtration and re-crushing of the material.

[0028] like Figure 1 , Figure 4 and Figure 6 As shown, in some embodiments, the filtering and re-grinding mechanism 7 includes a feed pipe 701 fixed at the outlet of the feed box 6. The bottom end of the feed pipe 701 is fixedly connected to a conveying cylinder 702. A rotating shaft 703 is rotatably connected inside the conveying cylinder 702. A spiral blade 704 is fixedly connected to the rotating shaft 703. A second motor 705 is fixedly connected to the left side wall of the conveying cylinder 702. The drive end of the second motor 705 is fixedly connected to the left end of the rotating shaft 703. An installation port is opened at the bottom of the conveying cylinder 702, and a screen 706 is sealed and fixedly connected inside the installation port. The second motor 705 drives the rotating shaft 703 to rotate, thereby driving the spiral blade 704 to rotate, conveying the material entering the conveying cylinder 702 from left to right. An installation port is opened at the bottom of the conveying cylinder 702 and a screen 706 is sealed and fixedly connected. During the material conveying process, the material that meets the particle size requirements falls through the screen 706, while the material that does not meet the requirements continues to be conveyed to the connecting box 707.

[0029] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, a connecting box 707 is fixedly connected to the right end of the conveying cylinder 702, a screen ring 708 is fixedly connected inside the connecting box 707, a connecting shaft 709 is rotatably connected to the center of the right side wall of the connecting box 707, a crushing paddle 7010 is fixedly connected to the inner end of the connecting shaft 709, and a first drive wheel 7011 is fixedly connected to the outer end of the connecting shaft 709. The first drive wheel 7011 is driven by a second drive wheel 7013 through a toothed belt 7012, and the second drive wheel 7013 is fixedly connected to its shaft end near the crushing roller 2. When the crushing roller 2 rotates, the connecting shaft 709 is driven to rotate through the transmission of the second drive wheel 7013, the toothed belt 7012 and the first drive wheel 7011, thereby causing the crushing paddle 7010 to rotate. The material that does not meet the particle size requirements conveyed from the conveying cylinder 702 enters the connecting box 707 and is crushed again under the action of the crushing paddle 7010. The crushed material falls down after being screened by the screen ring 708.

[0030] like Figure 2 and Figure 6 As shown, in some embodiments, a guide frame 7014 is fixedly connected between the conveying cylinder 702 and the connecting box 707, and a fixing column 7015 is fixedly connected to the top of the connecting box 707. The top of the fixing column 7015 is fixedly connected to the guide box 6. The guide frame 7014 plays the role of guiding the material, and the fixing column 7015 plays the role of supporting and fixing the connecting box 707, ensuring the stability of the connecting box 707, and enabling the entire filtration and re-crushing mechanism 7 to work normally.

[0031] like Figure 1 and Figure 2As shown, in some embodiments, two fixed ears 8 are symmetrically and fixedly connected to the left and right side walls of the feed box 6, and support legs 9 are fixedly connected to the lower end face of each fixed ear 8; the support legs 9 support the entire crushing device, place the device stably on the ground, and ensure the stability and safety of the device during operation.

[0032] like Figure 1 and Figure 3 As shown, in some embodiments, a feed hopper 10 is fixedly connected to the upper end face of the crushing box 1, and two guide plates 11 are symmetrically and fixedly connected inside the crushing box 1. The two guide plates 11 are arranged on the upper side of the crushing rollers 2. The feed hopper 10 provides an inlet for the input of organic fertilizer raw materials, making it convenient for operators to add raw materials into the crushing box 1. The guide plates 11 play a role in guiding the materials so that the materials can fall accurately between the two crushing rollers 2, thereby improving the crushing efficiency.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
