Technical Field
[0001] This utility model relates to the field of agricultural organic waste crushing technology, and in particular to an agricultural organic waste crushing device. Background Technology
[0002] With the continuous expansion of agricultural production, the amount of agricultural organic waste generated is increasing daily. As a major agricultural country, my country produces hundreds of millions of tons of crop straw annually, such as wheat, rice, and corn straw. In addition, the agricultural product processing process generates a large amount of waste, such as fruit peels and pits from fruit processing, leftover stems and leaves from vegetable processing, and livestock and poultry breeding waste, such as livestock and poultry manure and bedding, which are also considerable in quantity. If these wastes are not properly treated, they will not only occupy a large amount of land but also pollute the environment. Therefore, improving the resource utilization rate and reducing environmental pollution is urgent. This has prompted agricultural producers and related enterprises to actively explore effective treatment technologies and equipment. Among them, agricultural organic waste crushing equipment, as a key pretreatment, is becoming increasingly important. However, some existing crushing equipment has shortcomings. On the one hand, due to unreasonable blade design or crushing chamber structure problems, the particle size of the crushed material varies greatly, and the particle uniformity is poor. On the other hand, the service life of vulnerable parts such as blades and screens is short, requiring frequent replacement. Moreover, some equipment structures are not conducive to the replacement and maintenance of vulnerable parts, which increases the difficulty and time cost of maintenance. Utility Model Content

A waste receiving frame 9 is movably placed between the four support legs 8.
[0032] In this embodiment, the detachable shredder structure 5 includes an inner mounting hollow shell 51. T-shaped inserts 52 are fixedly connected to both the front and rear sides of the outer surface of the inner mounting hollow shell 51. Positioning openings 53 are provided on the right side of each T-shaped insert 52 near the shredder box 1. Through-hole screw holes 54 are provided on the right side of each T-shaped insert 52 away from the shredder box 1. A shredder assembly 55 is fixedly connected to the middle of the right end of the inner mounting hollow shell 51. The inner mounting hollow shell 51 is movably connected to the shredder box 1 via the two T-shaped inserts 52 and the two T-shaped slots 13. The right side of the inner mounting hollow shell 51 is located inside the through-hole 12. The two positioning holes 53 are respectively engaged with the front and rear right ends of the crushing box 1. The two T-shaped inserts 52 are detachably connected to the crushing box 1 through two screw holes 54 and two screws 4. The crushing blade assembly 55 includes a driver 551, which is fixedly connected to the right end of the inner mounting hollow shell 51. The output end of the driver 551 passes through the middle of the right end of the inner mounting hollow shell 51 and is fixedly connected to the main gear 552. The main crushing blade assembly is fixedly connected to the middle of the left end of the main gear 552. The main crushing roller 553 has its left end movably connected to the inner mounting hollow shell 51 via a bearing. A rear gear 554 is located directly behind the main gear 552, and its right end is movably connected to the inner mounting hollow shell 51 via a bearing. A rear crushing roller 555 is fixedly connected to the middle of the left end of the rear gear 554. A front gear 556 is located directly in front of the main gear 552, and its right end is movably connected to the inner mounting hollow shell 51 via a bearing. A front crushing roller 557 is fixedly connected to the middle of the left end of the front gear 556. The main gear 552, rear gear 554, and front gear 556 are all located inside the right side of the inner mounting hollow shell 51 and do not contact the inner mounting hollow shell 51. The main gear 552 is meshed with the rear gear 554, and the main gear 552 is meshed with the front gear 556. The main crushing blade roller 553 and the rear crushing blade roller 555 do not contact each other, and the main crushing blade roller 553 and the front crushing blade roller 557 do not contact each other. The rear crushing blade roller 555 and the front crushing blade roller 557 are both in close contact with the inner wall of the inner mounting hollow shell 51 but do not contact each other.
[0033] Through the above scheme: the inner mounting hollow shell 51 of the detachable crusher structure 5 is movably inserted into the T-slot 13 of the crushing box 1 via a T-shaped insert 52, the positioning port 53 is snapped into the crushing box 1, and then fixed with screws 4 through screw holes 54 to ensure stable installation and accurate positioning. The driver 551 of the crusher assembly 55 provides power, and its output end drives the main gear 552 to rotate. The main gear 552 meshes with the rear gear 554 and the front gear 556, so that the main crusher roller 553, the rear crusher roller 555 and the front crusher roller 557 are synchronized. As the main gear 552, rear gear 554, and front gear 556 rotate, the right side of the inner hollow shell 51 is not in contact with the shell wall, ensuring efficient power transmission. The crushing blade rollers do not contact each other, and they work together to crush materials from different positions, avoiding uneven particle size caused by crushing by a single blade or a single position. At the same time, the rear crushing blade roller 555 and the front crushing blade roller 557 are close to the inner wall of the inner hollow shell 51 but do not contact each other, ensuring stable operation. Therefore, the cooperation between the components reduces crushing defects caused by unreasonable structure and improves the particle uniformity of the crushed material.
[0034] In this embodiment, the waste screening structure 7 includes a filter screen frame 71. A handle 72 is fixedly connected to the middle of the front end of the filter screen frame 71, and a positioning block 73 is fixedly connected to the middle of the rear end of the filter screen frame 71. The rear end of the filter screen frame 71 is movably engaged with the lower part of the inner rear wall of the small discharge hopper 6 through the positioning block 73. The filter screen frame 71 is located directly above the waste receiving frame 9.
[0035] With the above scheme: In the waste screening structure 7, the positioning block 73 is inserted into the lower part of the rear wall of the small feed hopper 6, so that the filter screen frame 71 is stably installed in the small feed hopper 6. The waste falling from the crushing equipment is screened by the filter screen frame 71. The material that meets the particle size falls through the filter screen, while the material that does not meet the size remains in the screen frame. The handle 72 makes it easy for the operator to remove the filter screen frame 71 from the small feed hopper 6 for cleaning or replacement by pulling the handle 72.
[0036] It should be noted that this utility model is an agricultural organic waste crushing equipment. During use, firstly, the operator feeds the agricultural organic waste through the large hopper 3 and rectangular opening 10 into the crushing box 1. Then, the inner hollow shell 51 of the detachable crushing blade structure 5 is installed and movably inserted into the T-shaped slot 13 inside the crushing box 1 via T-shaped inserts 52. The positioning port 53 is engaged with the crushing box 1, and then screws 4 are used to fix it through screw holes 54 to ensure a stable installation. The driver 551 of the crushing blade assembly 55 is activated, driving the main gear 552 to rotate. The main gear 552 meshes with the rear gear 554 and the front gear 556, causing the main crushing blade roller 553, the rear crushing blade roller 555, and the front crushing blade roller 557 to rotate synchronously, allowing for crushing from different positions. Waste entering the crushing chamber 1 is crushed. The crushed material then enters the small hopper 6 through the connecting arc-shaped discharge port 11. The filter frame 71 inside the small hopper 6 is engaged with the lower rear wall of the small hopper 6 via a positioning block 73, screening the material. Material meeting the particle size requirements falls through the filter frame 71 into the waste receiving frame 9 below, while non-compliant waste remains inside the filter frame 71. Finally, when the filter frame 71 needs cleaning or replacement, the operator can remove it by pulling the handle 72. Therefore, the improved coordination between components reduces crushing defects caused by unreasonable structure, improves the uniformity of the crushed material particles, and facilitates the disassembly and replacement of the crushing blade assembly, thereby extending the service life of the equipment.
