Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of straw returning machines, specifically to an agricultural machinery shock-absorbing straw returning machine. Background Technology
[0002] In the fields of agricultural straw treatment and farmland maintenance, straw return machines are the core equipment for realizing the resource utilization of straw. Their operation mode and stability directly determine the straw treatment effect and the convenience of subsequent cultivation. As agricultural production demands more precision in operations and adaptability to different scenarios, the shortcomings of traditional straw return machines are becoming increasingly apparent: existing straw return machines generally lack the function of fixed-point input and treatment, can only move with the tractor vehicle, and lack effective shock absorption design. They cannot adapt to the needs of localized concentrated straw treatment, and are prone to vibration affecting the equipment's lifespan and operating accuracy, making it difficult to meet the diverse farmland operation scenarios.
[0003] Traditional straw-crushing and returning machines are often rigidly connected to vehicles such as tractors. During operation, they need to move with the vehicle to complete the straw crushing and returning process, making it impossible to stop and process in specific areas (such as the edge of the field or where crop residues are piled up). When dealing with areas with dense straw or plots requiring special improvement, the vehicle needs to be moved repeatedly to adjust its position, which is not only cumbersome but also prone to compacting the soil in non-target areas. At the same time, during mobile operation, the vibration of the equipment and vehicle is directly transmitted to the straw-crushing machine body, causing accelerated wear at the connection between the crushing parts and the frame. With long-term use, parts may loosen, affecting the crushing accuracy and even causing safety hazards.
[0004] Therefore, developing a shock-absorbing straw returning machine for agricultural machinery with fixed-point input processing function and integrated shock absorption design has become an urgent need to improve operational flexibility and equipment stability. Utility Model Content
[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an agricultural machinery shock-absorbing straw returning machine, which solves the technical problem that existing straw returning machines generally do not have the function of fixed-point input and processing, and can only follow the tractor vehicle to move and operate.
[0006] According to one aspect, at least one embodiment of this disclosure provides an agricultural machinery shock-absorbing straw returning machine, comprising: The housing and the receiving cover, wherein the receiving cover is fixed to the top of the housing; A pulverizing and ejecting assembly, wherein the pulverizing and ejecting assembly is disposed within the housing; A movable stabilizing component is disposed at the bottom of the housing; The pulverizing and ejecting assembly includes several inlets, all of which are located on the top of the outer casing. A pair of feed rollers are horizontally rotatably connected inside the outer casing, one of which is electrically driven to rotate. A rotating shaft is horizontally rotatably connected to the outer casing, and a spiral blade is provided on the surface of the rotating shaft. A pulverizing cutter is provided on the outer end face of the spiral blade.
[0007] As a further technical solution, the rotating shaft is driven to rotate by electricity, and a pair of central baffles are horizontally rotatably connected inside the housing. The central baffles are both located at the bottom of the feed rollers, and the spacing between the central baffles matches the spacing between the pair of feed rollers.
[0008] As a further technical solution, one side of the outer shell has an open structure, and a central cover is connected to the side surface of the outer shell. The central cover is connected to the outer shell, and a fan mounting groove is opened on the outer surface of the central cover. The fan mounting groove is connected to the inside of the central cover.
[0009] As a further technical solution, one end of the centralized cover is bent upward, a spray nozzle is provided on the outer surface of the centralized cover, and a number of shields are provided on the outer surface of the centralized cover, all of which cover the spray nozzle.
[0010] According to another aspect, in at least one embodiment of the present invention, the movable stabilizing component includes a pair of base frames, both of which are fixed to the bottom of the outer shell. Rectangular openings are provided at both ends of the bottom surface of each base frame, and supporting moving wheels are rotatably connected to both ends of each base frame. The supporting moving wheels are all located at the rectangular openings.
[0011] As a further technical solution, both sides of the receiving cover are hollowed-out mesh structures.
[0012] As a further technical solution, the shredder has a double-edged structure and slides against the inner wall of the outer shell.
[0013] As a further technical solution, the surface of the feed roller is a rough, frosted structure.
[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the pulverizing and spraying assembly solves the problems of excessive vibration and incomplete pulverization in traditional equipment through a progressive pulverization and vibration reduction design. Multi-channel inlets improve feeding efficiency, while the abrasive roller smoothly guides the material, reducing impact. Spiral blades, combined with a double-edged pulverizing cutter, achieve progressive pulverization, avoiding vibration caused by severe impacts. The cutter's contact with the inner wall also scrapes away residue. A central baffle prevents straw displacement, ensuring balanced force and further reducing vibration. The curved structure of the centralized hood buffers airflow impact, and the shielding hood controls the spray range, reducing splashing and airflow vibration. This structure significantly reduces overall equipment vibration, extends component life, and is suitable for targeted treatment scenarios, meeting the needs of refined field return.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0023] like Figures 1-4 As shown, it illustrates an agricultural machinery shock-absorbing straw returning machine according to an embodiment of the present disclosure, comprising: The housing 1 and the receiving cover 2 are fixed to the top of the housing 1; A pulverizing and ejecting component 3 is disposed in the outer casing 1; A movable stabilizing component 4 is disposed at the bottom of the housing 1; The pulverizing and ejecting assembly 3 includes several inlets 3-1, all of which are located on the top of the outer casing 1. A pair of feed rollers 3-2 are horizontally rotatably connected inside the outer casing 1, one of which is electrically driven. A rotating shaft 3-3 is horizontally rotatably connected to the outer casing 1. Spiral blades 3-4 are arranged on the surface of the rotating shaft 3-3, and pulverizing cutters 3-5 are arranged on the outer end faces of the spiral blades 3-4. The rotating shaft 3-3 is electrically driven. A pair of centering baffles 3-6 are horizontally rotatably connected inside the outer casing 1, both located at the bottom of the feed rollers 3-2. The spacing between the baffles 3-6 matches the spacing between the pair of feed rollers 3-2. One side of the outer shell 1 has an open structure. A concentrator 3-7 is connected to the side surface of the outer shell 1. The concentrator 3-7 is connected to the outer shell 1. A fan mounting groove 3-8 is opened on the outer surface of the concentrator 3-7. The fan mounting groove 3-8 is connected to the inside of the concentrator 3-7. One end of the concentrator 3-7 is bent upward. A spray nozzle 3-9 is opened on the outer surface of the concentrator 3-7. Several shields 3-10 are provided on the outer surface of the concentrator 3-7. All shields 3-10 cover the spray nozzle 3-9.
[0024] In some examples, in order to achieve efficient straw crushing and reduce equipment vibration, and to avoid severe vibration during the crushing process from affecting the life of components or crushing accuracy, a crushing ejection component 3 is designed. This component includes several inlets 3-1 on the top of the outer shell 1 to provide multiple entry paths for straw, which can simultaneously accept a large amount of straw and improve feeding efficiency. A pair of horizontally rotating feed rollers 3-2 (one of which is electrically driven) inside the outer shell 1 can smoothly guide the incoming straw into the crushing area, avoiding straw accumulation at the inlet and causing jamming. At the same time, the synchronous rotation of the feed rollers 3-2 can reduce the impact when the straw is introduced, and initially reduce the vibration of the feeding process.
[0025] The rotating shaft 3-3 inside the outer casing 1 is equipped with spiral blades 3-4. When the crushing cutter 3-5 on the outer end face rotates at high speed with the rotating shaft 3-3, the spiral blades 3-4 can gradually push the straw towards the crushing cutter 3-5 to achieve progressive crushing. Compared with traditional impact crushing, it is more stable and greatly reduces vibration during the crushing process. The horizontal installation of the rotating shaft 3-3 and the stable output of the electric drive ensure uniform rotation speed and avoid vibration caused by speed fluctuations.
[0026] Inside the outer casing 1, a pair of horizontally rotating centering baffles 3-6 are located at the bottom of the feed roller 3-2. Their spacing matches that of the feed roller 3-2, which can provide secondary guidance for the straw and prevent the straw from shifting, causing the crushing cutter 3-5 to be subjected to force on one side, further reducing the vibration caused by uneven force. At the same time, the centering baffles 3-6 can also prevent insufficiently crushed straw from directly entering the subsequent stages, ensuring thorough crushing.
[0027] The collection hood 3-7 on one side of the outer shell 1 is connected to the outer shell 1 and can collect the crushed straw. The fan in the fan mounting slot 3-8 generates airflow to transport the straw from one end of the curved collection hood 3-7 to the spray nozzle 3-9. The curved structure can buffer the airflow impact and reduce the vibration of the conveying process. The shield hood 3-10 at the spray nozzle 3-9 can adjust the straw spraying range to avoid straw splashing and reduce the equipment vibration caused by airflow leakage.
[0028] During operation, straw is guided by inlet 3-1, feed roller 3-2, and center baffle 3-6, then crushed by spiral blades 3-4 and crushing cutter 3-5, and discharged through collection hood 3-7 and spray nozzle 3-9. Spiral crushing reduces vibration, and multi-structure collaboration improves efficiency. All components work together to achieve straw crushing and vibration reduction, meeting the requirements of a vibration-damping straw returning machine.
[0029] like Figures 1-4 As shown in the figure, the movable stabilizing component 4 proposed in this embodiment includes a pair of base frames 4-1. The base frames 4-1 are both fixed to the bottom of the outer shell 1. Rectangular openings 4-2 are provided at both ends of the bottom surface of the base frame 4-1. Supporting moving wheels 4-3 are rotatably connected to both ends of the base frame 4-1. The supporting moving wheels 4-3 are all located at the rectangular openings 4-2.
[0030] In some examples, in order to enable the equipment to move stably on the ground and avoid the equipment from bumping or shifting due to uneven farmland, a moving stabilizing component 4 is designed. This component includes a pair of base frames 4-1 at the bottom of the outer shell 1 to provide the main load-bearing structure for the equipment. The base frames 4-1 are made of rigid material, which can distribute the overall weight of the equipment and prevent the outer shell 1 from directly contacting the ground and causing wear. At the same time, the symmetrical layout of the base frames 4-1 ensures that the equipment is subjected to balanced forces and prevents tilting caused by one-sided weight imbalance. The rectangular openings 4-2 at both ends of the bottom surface of the base frame 4-1 provide installation space for the support wheels 4-3. The support wheels 4-3, which are rotatably connected at both ends inside the base frame 4-1, are located at the rectangular openings 4-2, forming a stable support structure. The support wheels 4-3 at both ends of each base frame 4-1 can independently adapt to the undulations of the ground. Even in uneven farmland, the equipment can be kept stable by the flexible rotation of multiple wheels, avoiding instability caused by a single wheel being suspended in the air or under excessive pressure. The smooth rotation and wear-resistant material of the support wheels 4-3 ensure that the equipment can move stably on different ground surfaces (such as soft farmland and hard ground), reducing movement resistance. The base frame 4-1 is firmly fixed to the outer shell 1, which can transmit the traction force when the equipment moves. At the same time, the length design of the base frame 4-1 can increase the contact span between the equipment and the ground, further improving the stability of movement. The size of the rectangular opening 4-2 is adapted to support the moving wheels 4-3, ensuring that the wheels rotate without jamming and reducing vibration during movement.
[0031] During operation, the base frame 4-1 bears the weight of the equipment, while the supporting wheels 4-3 drive the equipment to move on the ground. The multiple wheels work together to adapt to the terrain. The multi-wheel support adapts to complex ground conditions, the base frame 4-1 ensures stability, and the coordinated operation of all components enables stable movement of the equipment, meeting the mobility requirements of the shock-absorbing straw returning machine.
[0032] For example, such as Figure 1 As shown, both sides of the receiving cover 2 are hollowed-out mesh structures.
[0033] In some examples, the perforated mesh structure on both sides of the receiving cover 2 allows for air circulation inside and outside the receiving cover 2, preventing straw from becoming moldy due to localized heat buildup when it accumulates inside the receiving cover 2. At the same time, it can quickly dissipate the heat generated by the crushing components during operation, preventing excessive internal temperature from affecting the lifespan of the components.
[0034] For example, such as Figure 3 As shown, the shredder 3-5 has a double-edged structure and slides against the inner wall of the outer shell 1.
[0035] In some examples, the double-edged structure of the shredder cutter 3-5 can cut straw in both directions, doubling the cutting efficiency compared to a single-edged cutter. The blade can also be flipped after wear, extending the cutter's service life. The shredder cutter 3-5 slides against the inner wall of the outer casing 1, scraping off straw residues adhering to the casing wall and preventing residue accumulation from affecting the shredding effect or causing equipment vibration.
[0036] For example, such as Figure 3 As shown, the surface of the feed roller 3-2 is a rough, frosted structure.
[0037] In some examples, the rough, frosted surface of the feed roller 3-2 can significantly enhance the friction with the straw, prevent the straw from slipping during the feeding process, ensure that the straw is stably conveyed to the crushing area, and reduce equipment vibration caused by straw jamming.
[0038] In practical use: Push the equipment to the farmland area where straw needs to be processed. The supporting casters 4-3 roll smoothly along the rectangular opening 4-2 of the base frame 4-1, adapting to uneven ground. Collect straw through the top receiving cover 2. The perforated mesh structure ensures air circulation, and the straw falls into the inlet 3-1 at the top of the outer shell 1. Start the crushing and spraying assembly 3. The electric drive pulley 3-2 (with a frosted surface to enhance friction) guides the straw in, and the central baffle 3-6 assists in guiding and preventing deviation. The rotating shaft 3-3 drives the spiral blades 3-4 to push the straw, and the outer double-edged crushing cutter 3-5 rotates at high speed against the inner wall of the outer shell 1, thoroughly crushing the straw. The crushed straw enters the collection cover 3-7. The fan in the fan mounting slot 3-8 generates airflow, conveying the straw along the curved collection cover 3-7 to the spray nozzle 3-9. The shielding cover 3-10 adjusts the spray range to evenly cover the farmland. For targeted processing, simply stop the equipment and continue feeding straw; there is no need to move with the tractor vehicle, achieving stable crushing and targeted return to the field throughout the entire process.

Although this disclosure 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 solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
