Description

Technical Field

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

[0002] Compound microbial fertilizer refers to a live microbial product composed of specific microorganisms and nutrients, which can provide, maintain or improve plant nutrition, increase the yield of agricultural products or improve their quality. In the production of compound microbial fertilizer, a crusher is required to uniformly crush the raw materials to facilitate the subsequent processing of compound microbial fertilizer.

[0003] Existing microbial fertilizer production raw material crushers, such as the raw material crushing device for bio-fertilizer production disclosed in publication number CN218736091U, have the advantage of adjusting the fineness of straw powder by changing the distance between the grinding base and the grinding blade. However, the crushing blade at the upper end of the drive shaft of this crusher is inconvenient to replace quickly and independently after it is damaged during use. Therefore, we propose a compound microbial fertilizer production raw material crusher. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0016] The following describes, with reference to the accompanying drawings, some embodiments of a compound microbial fertilizer production raw material crusher provided by this utility model.

[0017] Example 1: Combination Figure 1-6 As shown, the present invention provides a crusher for raw materials in the production of compound microbial fertilizer, comprising: a crusher body 100 and a replacement assembly 200; the crusher body 100 includes a casing 101, a fixed cover 102 fixedly installed on the casing 101, a drive shaft 103 movably installed inside the fixed cover 102, a motor 104 fixedly connected to one end of the drive shaft 103, and a movable door 105 rotatably connected to one end of the fixed cover 102, the motor 104 being fixed to the upper end of the casing 101; the replacement assembly 200 includes multiple sets of slots 201 arranged at one end of the drive shaft 103, and a movable door 105 movably arranged at the outer end of the slots 201. The sleeve 202, the blades 203 fixedly installed on both sides of the movable sleeve 202, the multiple sets of locking blocks 204 fixedly installed on the inner end of the movable sleeve 202, the threaded post 205 fixedly connected to one end of the drive shaft 103, the threaded cap 206 movably installed on the outer end of the threaded post 205, the movable door 105 also has a notch 207, the notch 207 also has a plane bearing 208 fixedly installed in it, the fixed cover 102 is also rotatably connected to one side of the screw rod 209, the threaded sleeve 210 is also movably installed on the screw rod 209, the movable door 105 also has a fixed ear 211 fixedly installed on one side of the movable door 105, and the locking block 204 and the locking groove 201 are matched.

[0018] Specifically, compound microbial fertilizer refers to a compound of specific microorganisms and nutrients. In the production of compound microbial fertilizer, a crusher is needed to uniformly crush the raw materials for subsequent processing. Multiple sets of blades 203 are arranged and installed on the slot 201 on one side of the drive shaft 103 in the main body 100 of this crusher. Each blade 203 has an independent mounting structure, allowing for individual maintenance and replacement of any damaged blade 203 via disassembly from the drive shaft 103, thus improving the convenience of blade 203 maintenance. Simultaneously, a threaded cap 206 installed on the threaded post 205 at one end of the drive shaft 103 can also be pressed against the outer end of the flat bearing 208 in the recess 207. The pressing and restraining effect of the flat bearing 208 prevents the threaded cap 206 from loosening and, in conjunction with the slot 201, keeps the blades 203 in place. The stable engagement of the inner locking block 204 improves the stability of the blade 203 on the drive shaft 103 during use. The plane bearing 208 can also rotate with the drive shaft 103 to reduce friction during operation. The blade 203 is stably installed on the outer end of the slot 201 by the locking block 204 at the inner end of the movable sleeve 202. The threaded cap 206 installed on the threaded column 205 is mainly used to press the blade 203 on the drive shaft 103 as a whole to prevent it from falling off. The screw 209 rotatably connected to one side of the fixed cover 102 and the threaded sleeve 210 at the upper end of the screw 209 are mainly used to press against the fixed ear 211 on one side after the movable door 105 is closed to lock the movable door 105 after it is closed, so as to ensure that the plane bearing 208 binds and blocks the threaded cap 206.

[0019] Working principle and usage process of this utility model: If a blade 203 at a certain position on the upper end of the drive shaft 103 is damaged, the threaded sleeve 210 at the upper end of the screw 209 can be unscrewed to open the movable door 105 at the outer end of the fixed cover 102. After the movable door 105 is opened, the flat bearing 208 will be released from the pressing and restraining of the threaded cap 206. At this time, the threaded cap 206 at the upper end of the threaded column 205 can be removed. After the threaded cap 206 is removed, multiple sets of blades 203 at the outer end of the drive shaft 103 can be disassembled to replace the damaged blade 203 individually. After the new blade 203 is replaced, the threaded cap 206 is tightened again to complete the pressing and fixing of multiple sets of blades 203 on the drive shaft 103. At the same time, after the movable door 105 is closed and locked by the threaded sleeve 210, the flat bearing 208 in the recess 207 will restrain and press against the outer end of the threaded cap 206 to prevent the threaded cap 206 from loosening during the operation of the drive shaft 103.

[0020] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
