Description

Technical Field

[0001] This utility model belongs to the field of agricultural waste crushing and processing equipment, and in particular relates to an agricultural waste processing device. Background Technology

[0002] As a major agricultural country, my country generates a large amount of agricultural waste every year, including corn stalks, straw, peanut shells, bean stalks, and firewood. These materials are rich in organic matter and nutrients, and improper disposal not only wastes resources but can also cause environmental pollution. Currently, one of the main ways to utilize these materials is by crushing them and using them as raw materials to produce organic fertilizer or feed, thereby achieving a circular economy in agriculture. In this process, straw crushers are key equipment, used to cut and crush various types of waste straw into fine fragments to meet the requirements of subsequent fermentation or molding processes.

[0003] Existing straw crushers typically include a feeding device, a crushing chamber, a blade system, and a discharge structure. Under the action of high-speed rotating blades, straw is crushed into smaller particles, which are then discharged through the outlet. However, because this type of material is lightweight and has loose fibers, it forms a large number of fine particles after crushing. During discharge, the disturbance caused by airflow and mechanical movement within the equipment makes these particles easily scattered and drifted away. Especially in the discharge area, the lack of effective enclosure or collection design causes the particles to be scattered by the wind, resulting not only in the loss of useful straw material and a reduction in the overall recycling rate, but also in dust pollution to the working environment. Utility Model Content

[0004] The purpose of this invention is to provide an agricultural waste treatment device that minimizes the loss of useful straw materials, reduces the overall recycling rate, and avoids dust pollution in the working environment.

[0005] The agricultural waste treatment device includes a straw crusher body and a dust cover. The top of the dust cover is provided with an upper connecting ring and the bottom is provided with a lower connecting ring. The upper connecting ring is sleeved on the discharge end of the straw crusher body. A shaped hose is installed between the upper connecting ring and the lower connecting ring.

[0006] Furthermore, the bottom of the upper connecting ring is provided with a first annular groove, and an upper retaining ring is provided in the first annular groove. The upper end of the dust cover is fixed on the upper retaining ring, and the upper retaining ring is locked in the first annular groove by a first fastening screw.

[0007] Furthermore, a second annular groove is provided at the top of the lower connecting ring, and a lower retaining ring is provided in the second annular groove. The lower end of the dust cover is fixed on the lower retaining ring, and the lower retaining ring is locked in the second annular groove by a second fastening screw.

[0008] Furthermore, the shaping hose consists of several tubes.

[0009] Furthermore, the dust cover is made of polyester.

[0010] Furthermore, the shaping hose is a gooseneck tube.

[0011] Furthermore, the lower connecting ring is made of aluminum.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model features an upper connecting ring at the top of a dust cover and a lower connecting ring at the bottom. The upper connecting ring is fitted onto the discharge end of the straw crusher body. The crushed straw can then be discharged along the inside of the dust cover and the lower connecting ring. During the discharge process, the dust cover prevents the straw crushing debris from being scattered by the wind, thus avoiding the loss of useful straw material, reducing the overall recycling rate, and also preventing dust pollution in the working environment.

[0013] By installing a shaping hose between the upper and lower connecting rings, the position of the dust cover and the lower connecting ring can be raised away from the ground by bending the shaping hose. This avoids the problem of the lower connecting ring and dust cover being easily affected by ground moisture, which can lead to rust and mold. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0016] Example This embodiment describes an agricultural waste treatment device, such as... Figure 1 As shown, the device includes a straw crusher body 1 and a dust cover 2. The straw crusher body 1 is a known existing product and is already in mass production. The straw crusher body 1 mainly consists of a feeding device, a crushing chamber (containing high-speed rotating hammers or blades), a screen, a power system (tractor power take-off shaft or electric motor), and a discharge device (discharge end 1.1). Its working principle is to use the power system to drive the rotor in the crushing chamber to rotate at high speed, causing the hinged hammers or fixed blades to generate huge impact and shearing forces, which violently strike, tear, and collide with the straw fed from the feed inlet. After the crushed material reaches the fineness specified by the screen, it is discharged, thus processing the long and thick straw into powder or short pieces in one go. Therefore, through the design of the straw crusher body 1, corn stalks, straw, peanut shells, bean stalks, and firewood in agricultural waste can be further processed, avoiding the needless burning of these crop straws, protecting the environment, and effectively developing renewable energy. Since the straw crusher body 1 is an existing known product, and this design does not improve the original structure of the straw crusher body 1, the straw crusher body 1 will not be described in detail. The dust cover 2 has a tubular structure; the dust cover 2 is used to discharge the crushed straw; after the straw is crushed into small particles by the straw crusher body 1, due to the light texture and loose fiber of this type of material, a large number of fine particles are formed after crushing. When discharged, due to the disturbance caused by the airflow and mechanical movement inside the equipment, it is very easy to be scattered and drifted; when the crushed straw is discharged through the inside of the dust cover 2, the dust cover 2 can cover the fine straw, prevent the straw fragments from being scattered by the wind, causing the loss of useful straw material, reducing the overall recycling rate, and also causing dust pollution to the working environment; like Figures 1-4 As shown, the dust cover 2 is provided with an upper connecting ring 3 at the top and a lower connecting ring 8 at the bottom; both the upper connecting ring 3 and the lower connecting ring 8 are horizontally arranged, and the dust cover 2 is connected to the upper connecting ring 3 and the lower connecting ring 8. like Figure 1 and Figure 2 As shown, the upper connecting ring 3 is sleeved on the discharge end 1.1 of the straw crusher body 1; specifically, the sleeve connection is implemented according to... Figure 2 In the middle position, the inner side wall of the upper connecting ring 3 can be fixed to the outer side wall of the discharge end 1.1 by welding. Because the dust cover 2 is connected to the upper connecting ring 3, when the upper connecting ring 3 is fixed on the discharge end 1.1, it can drive the dust cover 2 to be limited below the discharge end 1.1. At this time, the dust cover 2 can be connected and communicated with the discharge end 1.1. After the straw is crushed, it can be directly discharged into the dust cover 2 through the discharge end 1.1 and finally discharged from the lower connecting ring 8. like Figure 4 , Figure 5 and Figure 6 As shown, a shaped flexible tube 9 is installed between the upper connecting ring 3 and the lower connecting ring 8; the shaped flexible tube 9 is a gooseneck tube; the upper end of the shaped flexible tube 9 is fixed to the upper connecting ring 3, and its lower end is fixed to the lower connecting ring 8; the core advantage of the gooseneck tube lies in its extreme flexibility and directional freedom. It uses a specially designed metal snake skeleton internally, and is externally wrapped with wear-resistant and environmentally friendly PVC or rubber material, allowing it to bend arbitrarily within a 360-degree range and remain stable, like a swan's neck; the shaped flexible tube 9, in its vertical state, resembles... Figure 4 As shown in the structure, the bottom of the lower connecting ring 8 is aligned with the bottom of the straw crusher body 1, allowing the lower connecting ring 8 to contact the ground. The length design maximizes the coverage of the crushed straw. During use, according to… Figure 5 In this position, a collection box is placed below the discharge end 1.1 on the main body 1 of the straw crusher. Then, the dust cover 2 and the lower connecting ring 8 are placed inside the collection box. The crushed straw can then pass through the dust cover 2 and the lower connecting ring 8 into the collection box. When the straw is discharged through the discharge end 1.1, the dust cover 2, and the lower connecting ring 8, the dust cover 2 prevents small pieces of straw from flying out. After use, according to... Figure 6 The shaping hose 9 is flexible and stable, so when it bends, its vertical length shortens. This causes the lower connecting ring 8 to move upwards, which in turn moves the lower end of the dust cover 2 upwards. This prevents the lower connecting ring 8 from contacting the ground, allowing it and the dust cover 2 to be stored away from the ground when not in use. Since the ground is where moisture tends to accumulate, this design of raising the lower connecting ring 8 and dust cover 2 effectively prevents moisture from penetrating upwards, preventing rust on the lower connecting ring 8 and mold on the dust cover 2. During operation, the lower connecting ring 8's contact with the ground allows the dust cover 2 to effectively shield the crushed straw. The design of the shaping hose 9 raising the lower connecting ring 8 and dust cover 2 prevents the dust cover 2 from being too long and easily affected by ground moisture. The shaping hose 9 can also be the hose used on a desk lamp, and the desk lamp hose can be bent arbitrarily and held stably; There are several shaping hoses 9, preferably two shaping hoses 9, one at the front and one at the back. Only the shaping hose 9 at the front is shown in the figure. The one at the back is obscured and therefore not shown. The design of two hoses allows the shaping hose 9 to more stably lift the lower connecting ring 8 and the dust cover 2 upwards, increasing the stability during use. like Figure 1 and Figure 2As shown, the bottom of the upper connecting ring 3 has a first annular groove, and an upper retaining ring 5 is provided in the first annular groove. The upper end of the dust cover 2 is fixed to the upper retaining ring 5, and the upper retaining ring 5 is locked in the first annular groove by a first fastening screw 4. The left and right sides of the upper retaining ring 5 have first threaded holes that communicate with each other, and the left and right side walls of the upper connecting ring 3 have second threaded holes that communicate with the inside of the first annular groove. The center lines of the first threaded holes and the second threaded holes are on the same straight line. By screwing the first fastening screw 4 into the first threaded holes and the second threaded holes on both sides, the upper retaining ring 5 can be fixed in the first annular groove. The top of the dust cover 2 is connected to the bottom of the upper retaining ring 5. When the upper retaining ring 5 is fixed, the dust cover 2 connected to the upper retaining ring 5 can be limited. Then, by unscrewing the first fastening screw 4, the upper retaining ring 5 can be removed from the first annular groove, thereby achieving the purpose of disassembling the upper end of the dust cover 2. Therefore, the above design facilitates the disassembly and assembly of the upper end of the dust cover 2. like Figure 1 and Figure 3 As shown, the top of the lower connecting ring 8 has a second annular groove, and a lower retaining ring 6 is provided in the second annular groove. The lower end of the dust cover 2 is fixed to the lower retaining ring 6, and the lower retaining ring 6 is locked in the second annular groove by a second fastening screw 7. The left and right sides of the lower retaining ring 6 have third threaded holes that communicate with each other, and the left and right side walls of the lower connecting ring 8 have fourth threaded holes that communicate with the inside of the second annular groove. The center lines of the third threaded holes and the fourth threaded holes are on the same straight line. By screwing the second fastening screw 7 into the third threaded holes and the fourth threaded holes on both sides, the lower retaining ring 6 can be fixed in the second annular groove. The bottom of the dust cover 2 is connected to the top of the lower retaining ring 6. After the lower retaining ring 6 is fixed, the dust cover 2 connected to the lower retaining ring 6 can be limited. Then, by unscrewing the second fastening screw 7, the lower retaining ring 6 can be removed from the second annular groove, thereby achieving the purpose of disassembling the lower end of the dust cover 2. Therefore, the above design facilitates the disassembly and assembly of the lower end of the dust cover 2. Dust cover 2 is made of polyester. Polyester has many advantages, such as durability and shape retention, as well as high strength, wear resistance and long service life. The lower connecting ring 8 is made of aluminum, which is lightweight, easy to clean, and easy to extrude, cast, and process. In practical use: First, install the upper connecting ring 3 of this design on the discharge end 1.1 of the straw crusher body 1. Then, place the dust cover 2, the lower end, and the lower connecting ring 8 into the collection box. After that, open the straw crusher body 1 to crush the straw. The crushed straw can then be discharged into the collection box through the interior of the dust cover 2 and the lower connecting ring 8. During the process of the crushed straw being discharged into the collection box along the interior of the dust cover 2 and the lower connecting ring 8, because the lower connecting ring 8 can contact the ground, the problem of straw crushing debris being scattered by the wind, resulting in the loss of useful straw material, reducing the overall recycling rate, and causing dust pollution to the working environment is solved. After use, by bending the shaping hose 9 to move the dust cover 2 and the lower connecting ring 8 upward, the problem of the lower connecting ring 8 contacting the ground and causing corrosion, as well as the problem of the dust cover 2 being affected and developing mold, is avoided.
