Description

Technical Field

[0001] This utility model relates to the field of pulverizer technology, specifically to a pulverizing device for processing agricultural and forestry organic matter. Background Technology

[0002] Agricultural and forestry organic matter refers to plant residues generated during agricultural and forestry production. In agriculture, it mainly includes crop residues such as straw (e.g., wheat straw, corn straw, rice straw), vines (e.g., sweet potato vines), fruit shells (e.g., peanut shells, walnut shells), and vegetable remains. In forestry, it encompasses branches from tree pruning, timber residues from thinning and tending, fallen leaves, and bark.

[0003] Traditional methods for processing agricultural and forestry organic matter have many limitations. While direct incineration can quickly reduce the volume of organic matter, it releases large amounts of harmful gases into the atmosphere, such as sulfur dioxide, nitrogen oxides, and inhalable particulate matter. Furthermore, traditional pulverizers produce materials with extremely poor particle size uniformity, resulting in a mixture of coarse and fine particles. This cannot meet the precise particle size requirements of subsequent diversified utilization pathways such as biomass power generation, feed production, and organic fertilizer production. The uneven pulverization results hinder efficient conversion at each stage, greatly limiting the conversion and utilization rate of agricultural and forestry organic matter. Utility Model Content

[0038] Example 1

[0039] Reference Figures 1-3 This is the first embodiment of the present invention, which proposes a crushing device for treating agricultural and forestry organic matter, including a feeding device 1 with a feeding outlet side 101; a housing 2 disposed on one side of the feeding device 1, and the housing 2 communicating with the feeding outlet side 101; a crushing roller 3 rotatably disposed inside the housing 2; a filter plate 5 disposed on the bottom surface of the housing 2, the filter plate 5 and the housing 2 forming a crushing space 230, and the crushing roller 3 located inside the crushing space 230.

[0040] In the above scheme, the feeding device 1 adopts a conveyor belt structure with anti-slip texture on the surface of the conveyor belt. The feeding outlet side 101 is funnel-shaped to facilitate material falling into the housing 2. The housing 2 and the frame are bolted together. The crushing roller 3 is installed inside the housing 2 through bearings, which can adapt to high-speed cutting operations. The filter plate 5 is made of stainless steel perforated plate, installed on the bottom surface of the housing 2, and welded or bolted to the housing 2.

[0041] The entire assembly consists of a feeding device 1, a housing 2, a crushing roller 3, and a filter plate 5. The feeding device 1 conveys the material, and the housing 2 and the filter plate 5 form a crushing space 230, which serves as the area for crushing agricultural and forestry organic matter. The crushing roller 3 guides the material's movement. The crushing roller 3 performs the crushing task. After being crushed, the agricultural and forestry organic matter falls outside the housing 2 through the filter plate 5. Agricultural and forestry organic matter that does not meet the crushing requirements will continue to be crushed by the crushing roller 3 until it meets the requirements.

[0042] Working process: Agricultural and forestry organic matter is placed on the conveyor belt of the feeding device 1 and transported to the feeding outlet side 101, then falls into the crushing space 230 inside the housing 2. The crushing roller 3 rotates at high speed, crushing the material by friction and the blade structure. The crushed agricultural and forestry organic matter that meets the requirements will be collected through the filter plate 5, while large particles will remain in the crushing space 230 for further crushing until they meet the requirements. This achieves continuous operation from feeding to screening, significantly improving efficiency compared to traditional decentralized equipment, reducing manual intervention, and lowering labor intensity. The high degree of component integration and small footprint make it suitable for processing sites with limited space.

[0043] Furthermore, the longitudinal sections of both the shell 2 and the filter plate 5 are arc-shaped, and a crushing channel 231 is formed between the outer wall of the crushing roller 3 and the inner wall of the crushing space 230.

[0044] In the above scheme, the arc-shaped shell 2 and the filter plate 5 conform to the material crushing flow trajectory, reducing dead corners and allowing the material to be efficiently circulated and crushed in the channel. During operation, after the material enters the shell 2 from the feeding device 1, it is also moved along the crushing channel 231 by the crushing roller 3 during the cutting process. Agricultural and forestry organic matter that cannot be cut in one go will be repeatedly cut and torn by the blades, and the channel guides it to be crushed multiple times. After reaching the standard, it falls from the filter plate 5. This improves the uniformity of crushing, and the material becomes finer and more uniform in particle size after multiple cycles of crushing.

[0045] Furthermore, the crushing roller 3 includes a rotating shaft 4, which is rotatably mounted on both sides of the housing 2; there are several cutter discs 30, which are arranged on the rotating shaft 4, and the cutter discs 30 are keyed to the rotating shaft 4, with adjacent cutter discs 30 being staggered.

[0046] In the above scheme, the cutter disc 30 is made of high-quality carbon steel, and adjacent cutter discs 30 are staggered and securely connected to the rotating shaft 4 by a flat key, ensuring that they do not shift during high-speed rotation and fully cover the material. The staggered arrangement of multiple cutter discs 30 can increase the frequency of contact between the cutter and the material, improve the single-pass crushing efficiency, and ensure that no material is missed, resulting in more thorough crushing.

[0047] Furthermore, the cutter head 30 has a plurality of cutter heads 7, which are arranged circumferentially on the cutter head 30, and the cutter heads 7 and the cutter head 30 are an integral structure.

[0048] In the above solution, the integrated structure overcomes the drawbacks of traditional split blades, with a consistent and uniform material composition and stable mechanical properties; the triangular pyramidal blade head 7 provides good stress dispersion and a large cutting surface, improving the crushing effect. When the crushing roller 3 rotates, the cutter disc 30 with the blade head 7 spins and cuts the material at high speed. The blade head 7 penetrates the material, tearing and cutting, continuously refining the material through operation. The blades are durable, integrally molded, and not prone to falling off or breaking, resulting in a long service life, reducing downtime for blade replacement, ensuring continuous production, and providing excellent crushing effect.

[0049] Furthermore, it also includes a plurality of protrusions 6, which are spaced apart on the filter plate 5. The protrusions 6 are located in the crushing channel 231 and are staggered with the filter holes on the filter plate 5.

[0050] In the above scheme, the protruding strip 6 can be made of steel or high-toughness rubber, and is tightly welded or bolted to the filter plate 5. The protruding strip 6 can effectively reduce the number of times the material is carried up by the crushing roller 3, increase the crushing effect, and also achieve the effect of kneading and crushing the material, guiding the material that meets the requirements through the filter holes.

[0051] Furthermore, the filter plate 5 is bolted to the housing 2, which facilitates later cleaning and maintenance.

[0052] Furthermore, the housing 2 has a feed inlet 201, which is located on the side close to the housing 2, and the feed outlet side 101 is connected to the feed inlet 201.

[0053] Furthermore, the blade tip has a cutting bevel 701, which faces the same direction as the rotation of the blade disc 30.

[0054] In the above scheme, the regional processing center features a pulverizer blade 33 with a reasonably angled cutting bevel 701, finely ground surface, sharp cutting edge, and bevel orientation aligned with the rotation of the cutter disc 30. This angled orientation facilitates the cutting and decomposition of materials, improving pulverization efficiency.

[0055] Example 2, refer to Figure 4 The difference between this embodiment and Embodiment 1 is that the cutter head 30 includes a mounting plate 31, which has a plurality of slots 32 located near the edge of the mounting plate 31; there are a plurality of blades 33, each blade 33 having a snap-fit ​​protrusion 34, each snap-fit ​​protrusion 34 being inserted into a slot 32; and there are a plurality of fastening bolts for fixing the snap-fit ​​protrusions 34 into the slots 32.

[0056] In the above solution, the detachable blade 33 structure uses a dovetail groove for precise positioning and secure locking, preventing blade 33 displacement; it facilitates individual blade 33 replacement, reducing maintenance costs and improving component versatility. The motor drives the shaft 4 to rotate the cutter head 30, and the blade 33 cuts materials as it rotates with the mounting plate 31. When the blade 33 wears down, production can be resumed simply by stopping the machine, tightening the bolts, and replacing the blade 33. This reduces subsequent maintenance costs, significantly lowering the cost of replacing the blade 33 in fast-wearing conditions; it also shortens downtime for maintenance, ensuring efficient and continuous production and improving operational efficiency.

[0057] Furthermore, both the slot 32 and the snap-fit ​​protrusion 34 are dovetail-shaped.

[0058] In the above design, the trapezoidal cross-section of the dovetail groove has strong load-bearing capacity and wedges the blade 33 tightly. After the blade 33 protrudes from the slot 32, it can be tightened by screwing in the bolt, which facilitates the replacement of the blade 33.

[0059] Furthermore, the blade 33 has a cutting bevel 701, which faces the same direction as the rotation of the cutter head 30.

[0060] In the above solution, the blades cut the material 33 times when the cutter head rotates 30 revolutions. The inclined cutting cuts and tears the material, resulting in continuous crushing with smooth material flow and low energy consumption. This significantly reduces equipment energy consumption, resulting in marked energy savings compared to traditional methods; it also improves crushing efficiency, reduces equipment wear, and enhances overall profitability.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
