Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a corn stalk crushing and returning machine that can be used for both grain and feed. Background Technology

[0002] Laws and regulations prohibiting the burning of corn stalks in fields have spurred rapid development and progress in scientific research on corn stalk treatment and comprehensive utilization. Among these methods, returning crushed corn stalks to the field is one of the effective ways to comprehensively utilize straw. It avoids environmental pollution, turns waste corn stalks into valuable resources, and achieves the goals of improving soil structure, restoring and enriching soil fertility, and adapting to the development of green and organic agriculture. However, the degree of crushing required for returning corn stalks to the field has certain technical requirements; otherwise, the effectiveness of returning the corn stalks to the field will be affected, and they will not decompose easily.

[0003] Currently, due to the shortcomings in the structural design of existing corn stalk returning machines, the crushing quality and effect of corn stalks cannot meet the requirements for corn stalk returning to the field, thus reducing the effectiveness of corn stalk returning operations. Therefore, a new design has been developed to address this issue. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a dual-purpose (grain and feed) corn stalk crushing and returning machine, comprising a returning frame, with a baffle plate fixedly connected to the top of the frame. The baffle plate serves to prevent material from splashing, reducing particle pollution, optimizing the working environment, and reducing safety hazards for workers. A crushing component is rotatably connected at the midpoint between opposite surfaces of the returning frame. The crushing component is rotated by a motor, crushing the stalks to achieve the purpose of pulverizing them. This allows the stalks to be converted into fertilizer more quickly, without affecting cultivation, making the stalks easier for livestock to digest, reducing breeding costs, reducing environmental pollution, replacing burning, and achieving environmentally friendly treatment. A motor is fixedly connected to the middle of one side of the field frame. The output end of the motor is fixedly connected to one side of the outside of the crushing component. A connecting frame is fixedly connected to one side of the top of the baffle plate. The connecting frame is set on the drive motor to facilitate the movement of the equipment. Protective components are fixedly connected to the inclined parts on both sides of the outside of the baffle plate. When the straw comes into contact with the crushing component and splashes, it comes into contact with the protective components. The protective components rebound the straw, which promotes secondary crushing of the straw, thereby improving the crushing efficiency and quality of the straw. At the same time, it protects the components, reduces component collisions, reduces surface wear of the components, and thus extends the service life of the equipment. The protective assembly includes a protective frame. An electric push rod is fixedly connected to one side of the outer side of the protective frame. The distance between the protective plate and the crushing component is controlled by the electric push rod, which facilitates subsequent adjustment to meet different operational needs. A protective plate is fixedly connected to the outer side of the electric push rod near the crushing component. The protective plate rebounds the splashed straw pieces, causing the straw to come into contact with the crushing component, thereby achieving secondary crushing of the material and improving the crushing quality. A silicone plate is fixedly connected to the outer side of the protective plate away from the electric push rod. The silicone plate increases the wear resistance of the component surface, reduces surface wear, and extends the service life of the component.

[0005] Preferably, roller assemblies are fixedly connected to both sides of the outer side of the field-returning frame, and a pneumatic assembly is fixedly connected to the middle of the top of the baffle plate. The roller assemblies provide support for the equipment during movement, while the pneumatic assembly uses airflow to clean the crushing components, thereby removing impurities from the surface of the components, preventing impurities from adhering and affecting subsequent operation.

[0006] Preferably, the roller assembly includes an outer end, and a connecting rod is slidably connected to the inner side of the outer end. The connecting rod compresses and contracts the spring strip towards the outer end, thereby playing a role in shock absorption and buffering, reducing the vibration amplitude of the equipment, and improving the stability of the equipment during movement. A connecting frame is fixedly connected to the bottom of the connecting rod, and a receiving shaft is fixedly connected to the outer side of the connecting frame away from the connecting rod. A cylindrical block is rotatably connected to the outer side of the receiving shaft, and slides on the outer end via the connecting rod, so that the cylindrical block can undulate with the terrain, thereby improving the applicability of the component and improving the stability of the equipment operation. A spring strip is sleeved on the outer side of the connecting rod.

[0007] Preferably, the crushing component includes a connecting shaft, and an outer frame is fixedly connected to the outside of the connecting shaft. The outer frame adopts a dual-axis rotation design to increase the crushing range of the component and improve the crushing effect. A rotating shaft block is fixedly connected between the opposite surfaces of the outer frame. The rotating shaft block drives the crushing block to rotate, thereby achieving the purpose of crushing straw, turning straw into fertilizer faster, not affecting farming, making straw easier for livestock to digest, reducing breeding costs, reducing environmental pollution, replacing burning, and achieving environmentally friendly treatment. The crushing block is fixedly connected to the outside of the rotating shaft block.

[0008] Preferably, the pneumatic assembly includes a pneumatic frame, with a fan fixedly connected to the top of the frame. The fan uses airflow to clean the surface of the crushing assembly, thereby reducing particle adhesion, preventing it from affecting the subsequent crushing effect, preventing material blockage in the crushing assembly, ensuring continuous operation, cleaning the crushing assembly, reducing wear from impurities, assisting in the separation and conveying of chopped straw, improving the quality of returning straw to the field or recycling, reducing the risk of high temperature in the crushing assembly, and extending its service life. A grid cover is fixedly connected to the bottom of the fan, which prevents straw particles from entering and causing damage to the assembly. A friction mechanism is fixedly connected to the inner wall of the grid cover.

[0009] Preferably, the friction mechanism includes a fixed frame, a connecting shaft rotatably connected to the bottom of the fixed frame, a cylindrical shell fixedly connected to the outer side of the connecting shaft, and a paddle fixedly connected to the outer side of the cylindrical shell. The paddle drives the connecting shaft to rotate, causing the friction bracket to control the brush block to rub against the grid cover, thereby cleaning the particles on the surface of the component, reducing particle accumulation, avoiding blockage of the component's holes, preventing the airflow effect from being affected, and avoiding the blockage of holes from affecting the operation of the equipment. The friction bracket is fixedly connected to the bottom of the connecting shaft, and a brush block is fixedly connected to the outer side of the friction bracket away from the connecting shaft.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3This utility model provides a technical solution: a corn stalk crushing and returning machine for both grain and feed use, including a returning frame 1, a baffle plate 2 fixedly connected to the top of the returning frame 1, a crushing component 5 rotatably connected to the middle between opposite faces of the returning frame 1, a motor 6 fixedly connected to the middle of one side of the returning frame 1, and the output end of the motor 6 fixedly connected to one side of the outer side of the crushing component 5. A connecting frame 3 is fixedly connected to one side of the top of the baffle plate 2, and protective components 7 are fixedly connected to the inclined parts on both sides of the outer side of the baffle plate 2. The connecting frame 3 is mounted on a drive motor to facilitate the movement of the equipment, thereby enabling the equipment to move during operation. During the movement, the motor 6 controls the rotation of the crushing component 5, which crushes the stalks. The crushing component 5 crushes the straw, thereby achieving the purpose of pulverizing the straw, turning it into fertilizer more quickly without affecting cultivation, making the straw easier for livestock to digest, reducing breeding costs, reducing environmental pollution, replacing burning, and achieving environmentally friendly treatment. The baffle plate 2 prevents material from splashing, reduces particulate pollution, optimizes the working environment, and reduces safety hazards for personnel. During the process of straw splashing in contact with the crushing component 5, it comes into contact with the protective component 7. The protective component 7 rebounds the straw, promoting secondary crushing, thereby improving the crushing efficiency and quality of the straw, while also protecting the components, reducing component collisions, reducing surface wear, and thus extending the service life of the equipment.

[0017] The protective component 7 includes a protective frame 71. An electric push rod 72 is fixedly connected to one side of the protective frame 71. A protective plate 73 is fixedly connected to the side of the electric push rod 72 closest to the crushing component 5. A silicone plate 74 is fixedly connected to the side of the protective plate 73 furthest from the electric push rod 72. The distance between the protective plate 73 and the crushing component 5 is controlled by the electric push rod 72, facilitating subsequent adjustments to meet different operational needs. The protective plate 73 rebounds any splashed straw chunks, causing the straw to contact the crushing component 5, thus achieving secondary crushing of the material and improving the crushing quality. The silicone plate 74 increases the wear resistance of the component surface, reduces surface wear, and extends the service life of the component.

[0018] Roller assemblies 4 are fixedly connected to both sides of the outer side of the field-returning frame 1, and a pneumatic assembly 8 is fixedly connected to the middle of the top of the baffle plate 2. The roller assemblies 4 provide support for the equipment during movement, and the pneumatic assembly 8 uses airflow to flush the crushing assembly 5, thereby cleaning impurities from the surface of the components, preventing impurities from adhering and affecting the subsequent operation of the components.

[0019] The roller assembly 4 includes an outer end 41, with a connecting rod 42 slidably connected to the inner side of the outer end 41. A connecting frame 43 is fixedly connected to the bottom of the connecting rod 42. A receiving shaft 45 is fixedly connected to the outer side of the connecting frame 43 away from the connecting rod 42. A cylindrical block 46 is rotatably connected to the outer side of the receiving shaft 45. A spring strip 44 is sleeved on the outer side of the connecting rod 42. When the cylindrical block 46 contacts the ground, and the ground undulates, the connecting rod 42 compresses and contracts the spring strip 44 towards the outer end 41, thereby playing a role in shock absorption and buffering, reducing the vibration amplitude of the equipment, and improving the stability of the equipment during movement. The sliding of the connecting rod 42 on the outer end 41 allows the cylindrical block 46 to undulate with the terrain, thereby improving the applicability of the component and the stability of the equipment operation.

[0020] The crushing component 5 includes a connecting shaft 51, an outer frame 52 fixedly connected to the outer side of the connecting shaft 51, a rotating shaft block 53 fixedly connected between opposite faces of the outer frame 52, and a crushing block 54 fixedly connected to the outer side of the rotating shaft block 53. A motor 6 controls the rotation of the connecting shaft 51, causing the rotating shaft block 53 to drive the crushing block 54 to rotate, thereby achieving the purpose of crushing straw, allowing the straw to be converted into fertilizer more quickly, without affecting cultivation, making the straw easier for livestock to digest, reducing breeding costs, reducing environmental pollution, replacing burning, and achieving environmentally friendly treatment. The outer frame 52 adopts a dual-axis rotation design, thereby increasing the crushing range of the component and improving the crushing effect.

[0021] Please see Figure 4-5 The pneumatic assembly 8 includes a pneumatic frame 81, with a fan 82 fixedly connected to the top of the frame 81 and a grid cover 83 fixedly connected to the bottom of the fan 82. A friction mechanism 84 is fixedly connected to the inner wall of the grid cover 83. The fan 82 generates airflow, which acts on the surface of the crushing assembly 5 to flush and clean particles from the surface, reducing particle adhesion, preventing interference with subsequent crushing, preventing material blockage, ensuring continuous operation, cleaning the crushing components, reducing wear from impurities, assisting in the separation and conveying of chopped straw, improving the quality of straw return to the field or recycling, reducing the risk of high temperatures in the crushing components, and extending their service life. The grid cover 83 prevents straw particles from entering and damaging the components.

[0022] The friction mechanism 84 includes a fixed frame 841, a connecting shaft 842 rotatably connected to the bottom of the fixed frame 841, a cylindrical housing 843 fixedly connected to the outer side of the connecting shaft 842, a blade 844 fixedly connected to the outer side of the cylindrical housing 843, a friction bracket 845 fixedly connected to the bottom of the connecting shaft 842, and a brush block 846 fixedly connected to the outer side of the friction bracket 845 away from the connecting shaft 842. Wind force acts on the surface of the blade 844, causing the blade 844 to drive the connecting shaft 842 to rotate. This causes the friction bracket 845 to control the brush block 846 to rub against the grid cover 83, thereby cleaning particles from the component surface, reducing particle accumulation, preventing blockage of component holes, and avoiding affecting airflow and equipment operation.

[0023] During operation, the connecting frame 3 is mounted on the drive motor to facilitate equipment movement. During movement, the motor 6 controls the rotation of the crushing component 5, which crushes the straw, thus achieving the purpose of pulverizing the straw. This allows the straw to be converted into fertilizer more quickly, without affecting cultivation, making the straw easier for livestock to digest, reducing breeding costs, reducing environmental pollution, replacing burning, and achieving environmentally friendly treatment. The baffle 2 prevents material from splashing, reducing particulate pollution, optimizing the working environment, and reducing safety hazards for personnel. During the contact and splashing process between the straw and the crushing component 5, the straw comes into contact with the protective component 7. The protective component 7 rebounds the straw, promoting secondary pulverization, thereby improving the pulverization efficiency and quality of the straw. Simultaneously, it protects the components, reducing collisions and surface wear, thus extending the service life of the equipment.

[0024] The roller assembly 4 provides support for the equipment during its movement. The pneumatic assembly 8 uses airflow to clean the crushing assembly 5, thereby removing impurities from the surface of the components and preventing them from adhering to the surface. This also prevents the components from being affected in subsequent operations. By fully crushing the straw, it is easier to collect or return it to the field.

[0025] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
