Description

Technical Field

[0001] This utility model relates to the field of branch-type solid waste treatment technology, and in particular to a solid waste treatment device for resource utilization of solid waste. Background Technology

[0002] In agricultural production, the generation and treatment of agricultural and forestry solid waste is a significant issue restricting the green and sustainable development of agriculture. Sericulture and walnut farming, as pillar industries in some regions, generate large amounts of branch-like solid waste such as mulberry and walnut branches during production.

[0003] Currently, most branch-type solid waste is not being utilized properly. It is either directly piled up on field edges to rot naturally, causing land occupation and resource waste; or it is simply used as fuel, which easily generates environmental pollution during combustion, contradicting the requirements of "zero-waste city" construction and the concept of green development. To achieve the resource utilization of this type of solid waste, it is usually necessary to crush it and use it to make organic fertilizer, edible mushroom cultivation substrate, biomass fuel, etc., but existing solid waste treatment devices have many shortcomings in practical applications:

[0004] First, in the existing processing devices, the feed inlet needs to be fully opened when performing the crushing operation. The feed inlet lacks effective protection and automatic sealing structure, and wood chips are prone to splashing during the feeding process, which not only causes material loss, but may also pose a safety hazard to the operators.

[0005] Secondly, woody branches such as mulberry and walnut branches contain a large amount of fiber. After being crushed, they are prone to clumping due to fiber adhesion. The existing screening structure of the device is difficult to quickly break up the clumped material, which can easily cause screen blockage, affecting screening efficiency and the grading effect of crushed materials, and prolonging the solid waste treatment cycle. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the prior art by proposing a solid waste treatment device that utilizes solid waste resources.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a solid waste treatment device for the resource utilization of solid waste, comprising a mounting base and a crusher housing, wherein the crusher housing is fixedly connected to the mounting base, a cutting blade holder is rotatably connected inside the crusher housing, a brake motor for driving the cutting blade holder to rotate is fixedly connected to the mounting base, a protective housing is fixedly connected to the feed inlet of the crusher housing, two protective plates are symmetrically rotatably connected to the inner surface of the protective housing, and transmission gears are fixedly connected to the rotating shafts of the two protective plates through one side of the inner surface of the protective housing and extending outward, two symmetrically arranged sliding grooves are symmetrically arranged on the outer surface of the protective housing near the transmission gears, and transmission racks are slidably connected inside the two sliding grooves respectively, and two mounting plates are also symmetrically fixedly connected to the outer surface of the protective housing with the sliding grooves, and return springs are fixedly connected to the two mounting plates respectively, the ends of the two return springs being fixedly connected to the transmission racks on the same side respectively.

[0008] Preferably, the output shaft end face of the brake motor and the end face of the cutting tool holder rotating shaft near the brake motor are both fixedly connected to a transmission sprocket, and a transmission chain is provided between the two transmission sprockets.

[0009] Preferably, a filter cover is provided at the discharge port of the crusher shell, and the outer surface of the filter cover is provided with a number of sets of sieve holes in a circumferential array.

[0010] Preferably, a drive shaft is rotatably connected inside the filter cover, and several sets of stirring rods are fixedly connected in a circumferential array on the outer surface of the filter cover inside the drive shaft. An electric motor is also fixedly connected to the outer surface of the filter cover, and the output shaft of the electric motor is fixedly connected to one end face of the drive shaft.

[0011] Preferably, the filter cover and the pulverizer housing are both provided with fixing holes, and each pair of fixing holes is threaded with fixing bolts.

[0012] Preferably, an upward-opening material collection trough is fixedly connected to the bottom of the mounting base and directly below the bottom of the filter cover. One side of the outer surface of the material collection trough has a pull-out opening that communicates with the outside. A material collection drawer is slidably connected inside the pull-out opening.

[0013] Preferably, the outer surface of the material accumulation trough is provided with a transparent observation window, the length of which is equal to the length of the filter cover.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, during actual operation, when the operator puts in solid waste such as mulberry branches or walnut branches, the protective plate rotates under the pressure of the material and the pressing action of the operator, driving the transmission gear to rotate synchronously. Under the meshing action of the transmission rack, it moves along the direction of the tension return spring, gradually opening to form a feeding channel. When feeding is finished, the protective plate rotates in the opposite direction through the transmission rack and transmission gear under the rebound force of the return spring, realizing automatic closure on both sides and automatic sealing of the feed inlet. This avoids the problem of wood chips splashing during feeding, greatly reducing the safety hazards to the operator and reducing material loss.

[0016] 2. In this utility model, when the crushed wood chips and twigs enter the filter cover, the motor drives the transmission shaft to rotate at high speed, and the stirring rod on the transmission shaft also rotates at high speed to stir the material in all directions. This breaks up the clumps of material formed by fiber adhesion and prevents them from clogging the screen holes. At the same time, combined with the screen holes on the surface of the filter cover, the material that meets the particle size requirements can fall quickly, shortening the overall processing cycle and saving a lot of time for subsequent resource utilization. It also improves the speed of material classification and screening after being crushed by the brake motor-driven cutting blade holder, and improves the overall crushing efficiency of the device.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] like Figure 1-6 As shown, a solid waste treatment device for the resource utilization of solid waste includes a mounting base 1 and a crusher housing 2. The crusher housing 2 is fixedly connected to the mounting base 1. A cutting blade holder 3 is rotatably connected inside the crusher housing 2. A brake motor 4 for driving the cutting blade holder 3 to rotate is fixedly connected to the mounting base 1. A protective housing 5 is fixedly connected to the feed inlet of the crusher housing 2. Two protective plates 6 are symmetrically rotatably connected to the inner surface of the protective housing 5. The rotation shaft of the two protective plates 6 passes through the inner surface of one side of the protective housing 5 and is fixedly connected to the end face extending outward. Two symmetrically arranged sliding grooves 8 are symmetrically arranged on the outer surface of the protective housing 5 near the transmission gear 7. Transmission racks 9 are slidably connected inside the two sliding grooves 8 respectively. Two mounting plates 10 are also symmetrically fixedly connected to the outer surface of the protective housing 5 with the sliding grooves 8. Return springs 11 are fixedly connected to the two mounting plates 10 respectively. The ends of the two return springs 11 are fixedly connected to the transmission racks 9 on the same side respectively.

[0027] The output shaft end face of the brake motor 4 and the end face of the rotating shaft of the cutting tool holder 3 near the brake motor 4 are both fixedly connected to the transmission sprocket 12, and a transmission chain 13 is provided between the two transmission sprockets 12.

[0028] A filter cover 14 is provided at the discharge port of the crusher shell 2. The outer surface of the filter cover 14 is provided with several sets of screen holes 15 in a circumferential array.

[0029] A drive shaft 16 is rotatably connected inside the filter cover 14. Several sets of stirring rods 17 are fixedly connected in a circular array on the outer surface of the filter cover 14. An electric motor 18 is also fixedly connected to the outer surface of the filter cover 14. The output shaft of the electric motor 18 is fixedly connected to one end face of the drive shaft 16.

[0030] The specific working process and further beneficial effects of this solution are as follows: When feeding mulberry or walnut branches, the operator puts the cut mulberry or walnut branches into the feed inlet of the protective shell 5. These branches are solid waste, but under the pressure of the operator and their own weight, they will directly contact the two protective plates 6. As the branches are continuously fed in, they gradually overcome the elastic tension of the return spring 11 and push the two protective plates 6 to rotate around their own rotation axis inside the crusher shell 2. At this time, the transmission gear 7 at the extension end of the rotation axis of the protective plate 6 will rotate synchronously and drive the transmission rack 9 that meshes with it to slide along the sliding groove 8 on the protective shell 5. The return spring 11 is gradually stretched, forming an opening above the protective shell 5 and realizing a smaller feeding channel. When the feeding is completed, the mulberry or walnut branches no longer exert pressure on the protective plates 6. The elastic restoring force of the return spring 11 will pull the transmission rack 9 to slide in the opposite direction along the sliding groove 8, and then drive the protective plates 6 to rotate in the opposite direction through the transmission gear 7 until the two protective plates 6 close again, realizing the automatic sealing of the feed inlet.

[0031] Simultaneously, when the brake motor 4 drives the cutting blade holder 3 to rotate inside the crusher housing 2 via the transmission sprocket 12 and transmission chain 13, crushing the input mulberry or walnut branches, the crushed wood chips and small twig segments will enter the filter cover 14 from the discharge port of the crusher housing 2 due to the wood fiber content of the branches. At this time, the motor 18 fixed on the outer surface of the filter cover 14 is started. The output shaft of the motor 18 will drive the transmission shaft 16 connected to the inside of the filter cover 14 to rotate. Several sets of stirring rods 17 fixed in a circumferential array on the outer surface of the transmission shaft 16 will rotate synchronously at high speed with the transmission shaft 16, stirring the wood crushed material inside the filter cover 14 in all directions. Crushed materials are prone to clumping due to fiber adhesion. The stirring rod 17 can effectively break up the clumped materials, avoiding clogging of the several sets of screen holes 15 on the outer surface of the filter cover 14. At the same time, it accelerates the rapid fall of sawdust and small branches that meet the particle size requirements through the screen holes 15, while larger branches that do not meet the particle size requirements will remain in the filter cover 14 to continue to wait for subsequent processing, further improving the crushing efficiency of the device. In view of the adhesion characteristics of wood branch materials, it effectively improves the smoothness and efficiency of screening, shortens the overall processing cycle of mulberry branches and walnut branches, and ensures that the materials crushed by the brake motor 4 driving the cutting blade holder 3 can quickly complete the grading and screening, which will speed up the subsequent resource utilization of branches such as the production of organic fertilizer and biomass fuel.

[0032] like Figure 4As shown, the filter cover 14 and the crusher housing 2 are both provided with fixing holes 19, and each pair of fixing holes 19 is threaded with fixing bolts 20.

[0033] The purpose of this solution is that, during long-term crushing operations, shredded branches larger than the cross-sectional area of ​​the screen holes 15 on the surface of the filter cover 14 will remain inside the filter cover 14. When the filter cover 14 is filled with large shredded materials, or after the crushing operation is completed, the operator can disassemble the filter cover 14 by unscrewing the fixing bolts 20 in the fixing holes 19 and remove the large shredded materials. After reinstalling the filter cover 14, the device can be restarted, and the large shredded materials can be poured back into the device for further crushing, which greatly improves the utilization rate of waste materials.

[0034] The filter cover 14 can also be cleaned or replaced by disassembling it.

[0035] like Figure 2 and Figure 6 As shown, a material collection trough 21 with an upward opening is fixedly connected to the bottom of the mounting base 1 and directly below the bottom of the filter cover 14. A pull-out opening 22 communicating with the outside is provided on one side of the outer surface of the material collection trough 21, and a material collection drawer 23 is slidably connected inside the pull-out opening 22.

[0036] A transparent observation window 24 is also provided on the outer surface of the material trough block 21. The length of the transparent observation window 24 is equal to the length of the filter cover 14.

[0037] The effect is that the qualified mulberry or walnut branch crushed material, wood chips and small twigs, after being screened by the filter cover 14 will fall through the sieve holes 15 into the material accumulation trough 21 at the bottom of the mounting base 1 and directly below the filter cover 14. Since the material accumulation trough 21 is slidably connected to the material accumulation drawer 23, this type of wood material will fall directly into the material accumulation drawer 23 for centralized collection, avoiding the wood chips from scattering. When the operator observes the internal situation through the transparent observation window 24 opened on the outer surface of the material accumulation trough 21, whose length is equal to that of the filter cover 14, and finds that the amount of wood material accumulated in the material accumulation drawer 23 has reached the preset value, there is no need to disassemble the device. The material accumulation drawer 23 can be pulled out directly through the pull-out port 22 on one side of the material accumulation trough 21 to quickly take out the collected qualified mulberry or walnut branch crushed material.

[0038] The wiring diagrams of the brake motor 4 and the electric motor 18 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the brake motor 4 and the electric motor 18 will not be explained in detail.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
