Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a crushing device with an anti-entanglement blade. Background Technology

[0002] In mechanized agricultural operations, crushing equipment is widely used in processes such as straw return to the field, stubble crushing, and green manure burial. This type of equipment mainly uses high-speed rotating blades to crush and cut crop residues in the field.

[0003] Existing agricultural crushing equipment often suffers from reduced efficiency, increased energy consumption, or even damage due to materials such as weeds and vines entangled in the blades during operation. The entangled materials significantly increase the operating resistance of the equipment, leading to increased power loss and fuel consumption. In severe cases, it can even cause the cutter head to jam, the transmission system to overload and be damaged, or the blade fixing structure to loosen, posing safety hazards.

[0004] This application aims to provide a crushing device with an anti-entanglement blade, which can fundamentally and effectively prevent various flexible materials from entangled, ensure the continuous, efficient and stable operation of the device, and reduce safety hazards. Utility Model Content

[0005] The purpose of this invention is to provide a crushing device with an anti-entanglement blade, which can fundamentally and effectively prevent various flexible materials from entangled, ensure the continuous, efficient and stable operation of the device, and reduce safety hazards.

[0006] To achieve the above objectives, this utility model provides a crushing device with anti-entanglement blades, including a cutter disc, a cutter holder, and blades. The cutter disc is provided with five sets of anti-entanglement blades. Each set of anti-entanglement blades includes a cutter holder and at least one blade. The blade is a semi-arc triangular plate structure with a V-shaped anti-entanglement structure at the tail. The cutter holder is provided with a U-shaped groove to prevent the blade from loosening. The blade is installed in the cutter holder by insertion and is fastened with bolts. The cutter holders are arranged in a longitudinal array on the outer surface of the cutter disc. The V-shaped anti-entanglement structure is provided at the end of the blade. The V-shaped anti-entanglement structure actually forms a fixed, sharp "hook" or "scissor" structure. When the flexible, tangled material is thrown towards the base of the blade in the direction of rotation, it enters the V-shaped opening. The high-speed rotating blade generates enormous tensile and shearing forces. The two sharp sides of the V-shaped anti-tangling structure act like scissors, gripping and cutting the material. For tough vines, even if they cannot be cut instantly, the V-shaped anti-tangling structure will "hook" them and tear and break them under continuous rotational tension, thus preventing them from continuing to tangle. Some of the short grass clippings or lightweight materials that are cut off are thrown outward along the two inclined surfaces of the V-shape under the action of centrifugal force, instead of accumulating towards the axis. This reduces the possibility of material accumulating in the area at the base of the blade disc, keeping the blade disc area clean. This allows the V-shaped anti-tangling structure to effectively pick off and chop the tangled weeds and vines, thus playing an anti-tangling role.

[0007] The blade is 40mm wide and has a threaded hole that passes through it. The threaded hole is used to insert a bolt for fixing.

[0008] The tool holder has a threaded hole, which is used in conjunction with the wire hole.

[0009] The blade is provided with teeth, which are located on the side of the blade near the blade holder.

[0010] The blade holder has a triangular structure and is installed in conjunction with the blade.

[0011] This utility model discloses a crushing device with anti-entanglement blades, comprising a cutter disc, a cutter holder, and blades. The cutter disc is equipped with five sets of anti-entanglement blades. Each set includes a cutter holder and at least one blade. The blade has a semi-circular triangular plate structure with a V-shaped anti-entanglement structure at its tail. The cutter holder has a U-shaped groove to prevent the blade from loosening. The blade is installed on the cutter holder by insertion and secured with bolts. In use, the tail of the blade is inserted into the slot of the cutter holder, and the U-shaped groove and the protrusion on the blade lock the circumferential position. Then, a high-strength bolt is inserted into the threaded hole to secure the blade to the cutter holder, thus completing the installation of the blade. During operation, the cutter disc is driven to rotate at high speed, causing the cutter disc to drive the blade to rotate via the cutter holder. This allows the blade to cut soil and stubble. The V-shaped anti-entanglement structure at its tail can effectively break and chop entangled weeds and vines, thus achieving efficient, entangle-free operation. Attached Figure Description

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The first embodiment of this application is: Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of a crushing device with anti-entanglement blades. Figure 2 This is a diagram showing the installation of the blade and the tool holder. Figure 3This is a schematic diagram of the blade structure. This utility model provides a crushing device with anti-entanglement blades: it includes a cutter disc 101, a cutter holder 102, and blades 103. The cutter disc 101 is equipped with five sets of anti-entanglement blades. Each set of anti-entanglement blades includes one cutter holder 102 and at least one blade 103. The blade 103 has a semi-circular triangular plate structure with a V-shaped anti-entanglement structure at its tail. The cutter holder 102 has a U-shaped groove 105 to prevent the blade 103 from loosening. The blade 103 is installed in the cutter holder 102 by insertion and secured with bolts. The blade 103 has a threaded hole 106, the cutter holder 102 has a threaded hole 107, and the blade 103 has teeth 108. The aforementioned solution addresses the common problem in existing agricultural crushing equipment where materials such as weeds and vines entangle the blades 103 during operation, leading to decreased equipment efficiency, increased energy consumption, and even damage. Entangled materials significantly increase the equipment's operating resistance, resulting in increased power loss and fuel consumption. In severe cases, they can even cause the cutter head 101 to jam, the transmission system to overload and be damaged, or the blade 103's fixing structure to loosen, posing safety hazards. It is understandable that the aforementioned solution can fundamentally and effectively prevent the entanglement of various flexible materials, ensuring the continuous, efficient, and stable operation of the equipment, reducing safety hazards, and also making the cutting of the blades 103 more stable.

[0019] In this specific embodiment, the cutter head 101 is provided with five sets of anti-entanglement blades. Each set of anti-entanglement blades includes a cutter holder 102 and at least one blade 103. The blade 103 has a semi-arc triangular plate structure with a V-shaped anti-entanglement structure at the tail. The cutter holder 102 is provided with a U-shaped groove 105 to prevent the blade 103 from loosening. The blade 103 is installed in the cutter holder 102 by insertion and is fastened with bolts. The blade 103 is 40mm wide. The threaded hole 106 penetrates the blade 103 and is used to insert bolts for fixing. The threaded hole 107 is used in conjunction with the threaded hole 106. The cutter holders 102 are arranged in a longitudinal array on the outer surface of the cutter head 101. The end of the blade 103 is provided with the V-shaped anti-entanglement structure 104. The V-shaped anti-entanglement structure 104 actually forms a fixed, sharp "hook" or "scissor" structure. When the flexible tangled material is thrown towards the root of the blade 103 along the rotation direction, it enters the V-shaped opening. The high-speed rotating blade 103 generates enormous tensile and shearing forces. The two sharp sides of the V-shaped anti-tangling structure 104 act like scissors, gripping and cutting the material. For tough vines, even if they cannot be cut instantly, the V-shaped anti-tangling structure 104 will "hook" them and tear or break them under continuous rotational tension, thus preventing them from continuing to tangle. Some of the cut short grass clippings or lightweight materials are thrown outwards along the two inclined surfaces of the V-shape under centrifugal force, instead of accumulating towards the axis. This reduces the possibility of material accumulation in the root area of ​​the cutter head 101, keeping the area of ​​the cutter head 101 clean, and making the V-shaped anti-tangling structure effective. 104 can effectively cut and chop tangled weeds and vines, playing a role in preventing tangling. During installation, the tail of the blade 103 is inserted into the slot of the blade holder 102. The U-shaped slot 105 and the protrusion on the blade 103 are used to lock the circumferential position. Then, a high-strength bolt is inserted into the threaded hole 106 to the threaded hole 107 to fasten the blade 103 to the blade holder 102, thus completing the installation of the blade 103. During operation, the power drives the blade disc 101 to rotate at high speed, so that the blade disc 101 drives the blade 103 to rotate through the blade holder 102, so that the blade 103 cuts the soil and stubble. The V-shaped winding structure at its tail can effectively cut and chop tangled weeds and vines, thus achieving efficient and tangled-free operation.

[0020] The teeth 108 are located on the side of the blade 103 near the blade holder 102. The outer surface of the blade 103 is provided with the teeth 108. The teeth 108 improve the sharpness of the blade 103 during cutting, enhance the cutting effect, and provide a certain degree of anti-tangling effect.

[0021] Secondly, the tool holder 102 has a triangular structure and is installed in conjunction with the blade 103. The triangular structure of the tool holder 102 provides stable anti-rotation torque. When the blade 103 is working, it will be subjected to huge and uneven impact forces and resistance from the material. These forces will generate a strong torque. Through the triangular structure of the tool holder 102, the three sides of the triangle provide three clear resistance surfaces. When the torque attempts to rotate the blade 103, the blade 103 will transfer the force to at least two sides of the triangular tool holder 102. This multi-directional resistance greatly enhances the ability of the tool holder 102 to resist rotation, ensuring that the angle of the blade 103 remains absolutely fixed during operation and that the working state is extremely stable. The triangular structure of the tool holder 102 is a highly optimized design that integrates structural stability, mechanical performance, assembly convenience, and system functionality. It ensures that the blade 103 can withstand huge and variable impact forces under harsh working conditions and always remain stable, thus laying the foundation for the efficient and reliable operation of the entire equipment.

[0022] When using the crushing device with anti-entanglement blade of this embodiment, the tail of the blade 103 is inserted into the slot of the blade holder 102. The U-shaped slot 105 locks the circumferential position with the protrusion on the blade 103. Then, a high-strength bolt is inserted into the threaded hole 106 to the threaded hole 107 to fasten the blade 103 to the blade holder 102, thereby completing the installation of the blade 103. During operation, the power drives the cutter disc 101 to rotate at high speed, so that the cutter disc 101 drives the blade 103 to rotate through the blade holder 102, so that the blade 103 cuts the soil and stubble. The V-shaped winding structure at its tail can effectively cut and chop the entangled weeds and vines, thereby achieving efficient and entangle-free operation.

[0023] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
