Description

Technical Field

[0001] This invention relates to the field of grain storage technology, specifically to a grain storage cleaning device and its cleaning method. Background Technology

[0002] Existing warehousing operations, such as loading and unloading bagged grain, leveling, and cleaning, require a large amount of manual labor. Grain warehouses are equipped with several grain outlets. When grain is discharged from the warehouse, the outlets are opened, and the grain inside flows out autonomously under the action of gravity. However, due to factors such as the number of outlets, the shape, density, and friction of the grain itself, a large amount of grain still cannot be discharged from the warehouse by its own gravity after the grain flows out, requiring additional cleaning operations.

[0003] Currently, there are generally two methods for grain silo cleaning. One method involves driving a loader into the silo and pushing the remaining grain to the discharge port. However, the loader's back-and-forth movement within the shallow circular silo significantly increases the grain breakage rate. Furthermore, driving the loader and subsequent cleaning still require multiple people working together, resulting in high labor intensity and a harsh environment inside the silo, unsuitable for long-term human work and impacting the health of the workers. The other method involves installing a pre-embedded spiral cleaning machine in the grain silo. This machine needs to be installed in advance at the bottom of the silo, and one machine is required for each silo. The equipment investment cost is high, and for silos that are rotated every three years, the utilization rate of the equipment used only once every three years is extremely low. Moreover, since the equipment is buried at the bottom of the grain, it cannot be repaired if a malfunction occurs before use. After the grain is discharged, manual sweeping with brooms is still required, which is time-consuming and labor-intensive, affecting the efficiency of grain silo cleaning. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing grain warehouse cleaning methods, such as the lack of suitable cleaning equipment, time-consuming and labor-intensive cleaning operations, and high breakage rate, and to provide a grain warehouse cleaning equipment and cleaning method.

[0005] In a first aspect, the present invention provides a grain warehouse cleaning device, comprising:

[0006] A traveling mechanism, comprising a frame, the frame being provided with a track mechanism and a driving system, the track mechanism comprising a rubber outer layer, the driving system comprising a cab; The digging mechanism is connected to a rotating mechanism, which is detachably mounted on the vehicle frame. The digging mechanism includes a hydraulic articulated arm and a bucket, with the bucket being rotatably connected to the hydraulic articulated arm. A push-head mechanism is hinged to the vehicle frame and is hinged to a telescopic mechanism, which drives the push-head mechanism to rotate relative to the vehicle frame. The spiral transfer mechanism includes at least two spiral transfer mechanisms, which are hinged to the vehicle frame. The spiral transfer mechanism is connected to a drive cylinder, which drives the spiral transfer mechanism to swing relative to the vehicle frame. The at least two spiral transfer mechanisms have at least one workstation that can be aligned and connected to each other within the swing range.

[0007] This invention discloses a grain storage cleaning device that integrates multiple cleaning mechanisms on a chassis. This allows for cleaning operations tailored to different grain storage conditions, avoiding manual cleaning and improving efficiency. Specifically, the tracked mechanism with a rubber outer layer supports the walking frame, overcoming the problems of insufficient grip and slippage when walking on grain, and reducing grain breakage upon contact. The digging mechanism quickly clears grain accumulated behind the grain storage door, facilitating equipment entry into the grain storage area. The pushing mechanism pushes grain in front of the equipment's direction of travel, reducing the amount of grain crushed during movement, further lowering the breakage rate, and providing thrust to achieve the cleaning purpose, reducing cleaning difficulty and improving efficiency. The spiral conveying mechanism establishes a transport channel from the grain pile to the lower grain outlet, enabling smooth transport of grain from further away. The coordinated use of multiple spiral conveying mechanisms achieves full coverage of grain transport within the grain storage area, resulting in a superior cleaning effect.

[0008] Preferably, the excavating mechanism is arranged side by side with the cab, the pushing mechanism is located at least at the front end of the frame in the direction of travel, and the two spiral conveying mechanisms are arranged opposite each other on both sides of the frame. This rational arrangement of the mechanisms facilitates the clearing of surrounding grain during equipment movement.

[0009] Preferably, the driving system is configured to have both remote control and manual driving capabilities to ensure smooth warehouse clearing operations in different environments.

[0010] Preferably, the pusher mechanism includes a pusher plate component hinged to the frame. One end of the pusher plate component, away from the frame, is connected to a rubber section, and the other end is connected to a telescopic mechanism. The telescopic mechanism is mounted on the frame. The rubber section includes a rubber plate and / or several rubber teeth. The grain can be pushed forward while the equipment is moving by adjusting the pusher plate component to be flush with the ground.

[0011] Preferably, the vehicle frame is equipped with a shield, and the telescopic mechanism is detachably mounted on the side of the shield near the vehicle frame. The push plate component is hinged to the bottom end of the shield. The shield can prevent grain from entering the vehicle frame in the direction of travel.

[0012] Preferably, the spiral transfer mechanism includes a mounting frame and an auger mechanism, the auger mechanism being disposed within the mounting frame, and the mounting frame being connected to the vehicle frame via a pivot shaft. This allows the spiral transfer mechanism to swing closer to the vehicle frame, reducing the overall size of the equipment and facilitating its use.

[0013] Preferably, the bottom of the mounting frame is provided with several casters. This allows the spiral transfer mechanism to move smoothly along the ground during the swinging process, reducing the pressure on the frame and allowing the spiral transfer mechanism to be set longer.

[0014] Preferably, the auger mechanism includes a drive device and a screw mechanism, which are driven together. The drive device is located at one end of the mounting frame. This allows each screw conveyor mechanism to operate independently or in combination, adapting to the cleaning operation environment and improving the cleaning effect.

[0015] Preferably, a storage platform adapted to the mounting frame is provided on the vehicle frame, the rotating shaft is located at one end of the storage platform, and the drive cylinder is spaced apart from the rotating shaft. This facilitates the storage of the spiral conveying mechanism on the vehicle frame, reduces the size of the equipment, and facilitates the movement of the equipment in and out of the grain silo.

[0016] In a second aspect, the present invention provides a grain warehouse cleaning method, employing a grain warehouse cleaning device as described above, and comprising the following steps: S1. Move the grain storage equipment to the outside of the grain storage door, and use the digging and pulling mechanism to remove and transfer the grain behind the grain storage door to the grain unloading outlet; S2. The mobile grain warehouse cleaning equipment enters the grain warehouse. During the movement, the pusher mechanism pushes out the travel channel in front of the vehicle frame in the direction of travel. By adjusting the unfolding state of the spiral conveyor mechanism, the grain on the side of the vehicle frame is transported to the grain outlet. S3. Move the grain warehouse cleaning equipment along the walking path; S4, repeat S2-S3 until the inventory is cleared.

[0017] The present invention provides a grain warehouse cleaning method that, through the cooperation of multiple functional cleaning mechanisms, enables efficient and low-breakage grain cleaning operations within the grain warehouse.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention provides a grain warehouse cleaning device, which integrates a multi-functional cleaning mechanism on a vehicle frame to perform cleaning operations for different grain storage conditions, avoiding the difficulty of manual cleaning and improving cleaning efficiency; 2. The present invention provides a grain warehouse cleaning device, which can overcome the problems of insufficient grip and slippage of the walking mechanism when walking on grain by setting a track mechanism with a rubber outer layer to support the support frame, and reduce the breakage rate of grain when in contact with grain; 3. This invention provides a grain warehouse cleaning device, which can quickly clear the grain piled up behind the grain warehouse door by setting up a digging and pulling mechanism, thus facilitating the equipment to enter the grain warehouse for operation; 4. This invention provides a grain warehouse cleaning device. By setting a pusher mechanism, it can push the grain in front of the device in the direction of travel, reduce the amount of grain crushed by the device, further reduce the breakage rate, and provide pushing force to the grain to achieve the purpose of cleaning, reduce the difficulty of cleaning, and improve the efficiency of cleaning. 5.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0026] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer," etc., used in the description of specific embodiments of the present invention to indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0027] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the solution of the present invention.

[0028] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0029] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0030] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to connection methods commonly used in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0031] Example 1 like Figures 1-5 As shown, a grain warehouse cleaning device includes a traveling mechanism 1, on which multiple cleaning mechanisms with different functions are installed. Specifically, the cleaning mechanisms may include a digging mechanism 2, a pushing mechanism 3, and a spiral conveying mechanism 4.

[0032] The walking mechanism 1 is used to provide walking functionality for the grain warehouse cleaning equipment.

[0033] In one or more embodiments, the traveling mechanism 1 includes a frame 11, on which a track mechanism 12 and a driving system are mounted. The track mechanism 12 includes a rubber outer layer 14, and the driving system includes a cab 13. The frame 11 is the main body of the equipment, providing support and mounting positions for each cleaning mechanism. The track mechanism 12 is located at the bottom of the frame 11, driving the frame 11 to move and enabling self-propelled movement, steering, and climbing functions. The driving system provides power for the movement of the frame 11, driving the frame 11 to travel along a specified direction and route.

[0034] In an optional embodiment, the rubber outer layer 14 can be an outer layer structure built into the track, or it can be several rubber blocks set on the track. This can increase the friction with the ground or grain surface and overcome the resistance of the grain pile in front during the clearing process. When set as rubber blocks, several rubber blocks can be set at intervals to form gap spaces between adjacent rubber blocks. The gap spaces can penetrate the bottom surface and both sides of the width direction of the track mechanism 12, so that the contact surface between the rubber outer layer 14 and the ground is appropriate and the breakage rate of the grain is reduced.

[0035] In an optional embodiment, the driving system may include a power source, a reduction mechanism, and a control system for realizing driving function and clearing mechanism control function. The power source may be an electric motor, a gasoline or diesel engine, a hydraulic motor, etc. After adjustment by the reduction mechanism, the track mechanism 12 is driven. The control system for realizing driving function and the control system for realizing clearing mechanism control function can be set independently or integrated. The control system for realizing clearing mechanism control function may include a hydraulic control system with an integrated PLC logic controller.

[0036] In an optional implementation, the driving system can be equipped with both remote control and manual driving functions. This allows for smooth operation of the grain storage cleaning process under different conditions. When the environment inside the grain storage is unfavorable, the grain storage cleaning equipment can be moved and the actions of each cleaning mechanism can be controlled via remote control to carry out the cleaning operation. In case of emergency, the operator can enter the cab 13 to operate the equipment, ensuring the smooth and safe execution of the cleaning operation.

[0037] The digging and pulling mechanism 2 can be used to move the remaining grain behind the grain warehouse door to the lower grain outlet by a combination of digging and pulling before the equipment enters the grain warehouse. It can also be used to move the remaining grain in inconvenient locations such as the sides and corners of the grain warehouse after the grain warehouse cleaning equipment enters the grain warehouse.

[0038] In one or more embodiments, the digging and pulling mechanism 2 is connected to the rotating mechanism 21, which is detachably mounted on the frame 11. The digging and pulling mechanism 2 includes a hydraulic articulated arm 22 and a bucket 23, with the bucket 23 rotatably connected to the hydraulic articulated arm 22. The hydraulic articulated arm 22 is rotatably connected to the frame 11 via the rotating mechanism 21, allowing the digging and pulling mechanism 2 to rotate on the frame 11. The bucket 23 can also rotate relative to the hydraulic articulated arm 22, providing a high degree of freedom and adapting to digging and pulling operations of grain in different locations.

[0039] In an optional implementation, the excavating mechanism 2 is connected to the control system, and the movement control of the excavating mechanism 2 can be achieved through the control system.

[0040] In an optional embodiment, the rotating mechanism 21 can be a turntable combination mechanical component with planar rotation function set on the top of the frame 11. The rotating mechanism 21 can realize the rotation of the digging mechanism 2 relative to the frame 11 in the plane, adjust the operating direction of the digging mechanism 2, and make the digging mechanism 2 rotate within the vertical projection range of the frame 11, so as to reduce the overall volume of the equipment and facilitate the movement of the grain warehouse cleaning equipment into or out of the grain warehouse.

[0041] In an optional embodiment, the hydraulic articulated arm 22 can be a multi-link component connected by a hydraulic control system. The digging action of the digging mechanism 2 can be adjusted by the hydraulic control system. The bucket 23 is rotatably connected to one end of the hydraulic articulated arm 22 and can adjust the digging direction by the control system.

[0042] The pusher mechanism 3 is used to push the remaining grain in the direction of travel of the frame 11 forward, so as to facilitate the movement of the equipment in the grain bin, reduce the amount of grain crushed by the equipment, and can also be used to clear the walking path for the equipment to enter the grain bin, minimizing the grain breakage rate during the cleaning operation.

[0043] In one or more embodiments, the pusher mechanism 3 is hinged to the frame 11, and the pusher mechanism 3 is hinged to the telescopic mechanism 31. The telescopic mechanism 31 drives the pusher mechanism 3 to rotate relative to the frame 11. By adjusting the orientation of the pusher mechanism 3 through the telescopic mechanism 31, the grain can be swept during the rotation of the pusher mechanism 3. It can also be adapted to grain piles of different thicknesses, enabling layered pushing of thicker grain piles and reducing the difficulty of pushing the grain.

[0044] In an optional embodiment, the pusher mechanism 3 includes a pusher plate component 32, which is hinged to the frame 11. One end of the pusher plate component 32 away from the frame 11 is connected to a rubber part 33, and the other end is connected to a telescopic mechanism 31. The telescopic mechanism 31 is mounted on the frame 11. The rubber part 33 includes a rubber plate and / or several rubber teeth. The pusher plate component 32 can be a plate-shaped structure with a wide side. The pusher plate component 32 can swing back and forth relative to the frame 11 under the action of the telescopic mechanism 31. When the pusher plate component 32 is in a vertical state and flush with the ground, i.e., the wide side of the pusher plate component 32 is perpendicular to the ground, the rubber part 33 is installed on the lower part of the pusher plate component 32 and can fit in contact with the ground. It can push the grain under the action of the walking mechanism 1, or push the grain in layers during the swinging process under the action of the telescopic mechanism 31.

[0045] In an optional embodiment, the telescopic mechanism 31 can be a hydraulic cylinder. The telescopic mechanism 31 can be connected to a hydraulic control system. The action control of the telescopic mechanism 31 is realized through the hydraulic control system, thereby realizing the action control of the push plate component 32.

[0046] In an optional embodiment, the pusher plate member 32 can be a plate-shaped frame structure with a wide side formed by welding steel components. The cross-section of the pusher plate member 32 can be rectangular or it can be provided with an S-shaped arc surface, such as... Figure 5As shown, the cross-section of the push plate component 32 can be configured with two variable angle arc surfaces to facilitate the hinge connection between the push plate component 32 and the frame 11, and to allow the push plate component 32 to contact the grain through the arc surface during the grain pushing process, conforming to the flow characteristics of the grain, increasing the contact area with the grain, reducing the force applied to push the grain, and ensuring the smooth pushing of the grain.

[0047] In an optional embodiment, the frame 11 is provided with a shielding frame 15, and the telescopic mechanism 31 is detachably mounted on the side of the shielding frame 15 near the frame 11. The push plate component 32 is hinged to the bottom end of the shielding frame 15. The shielding frame 15 can be a frame structure that extends from the front end of the frame 11 and is connected thereto. The shielding frame 15 is set as a plate-shaped structure in front of the traveling mechanism 1. The projection of the plate-shaped structure in the traveling direction of the frame 11 can shield the front end face of the frame 11, so as to effectively prevent grain in front of the traveling direction of the equipment from entering the frame 11. At the same time, the shielding frame 15 can also provide an installation position for the telescopic mechanism 31, so that the shielding frame 15 can protect the telescopic mechanism 31 and ensure the normal operation and service life of the telescopic mechanism 31.

[0048] In an optional embodiment, the top and lateral sides of the shield 15 can also be configured as plate-shaped structural members, so that the telescopic mechanism 31 is located on the side of the shield 15 close to the frame 11 and is covered and shielded by the shield 15. The bottom of the telescopic mechanism 31 extends out of the shield 15 and is hinged to the push plate member 32.

[0049] In an optional embodiment, the pusher mechanism 3 can be set at the front end of the frame 11, or it can be set at the front and rear ends of the frame 11 respectively, so that the walking mechanism 1 can push and clean the grain during the forward and backward movement, which can further reduce the breakage rate of the grain under pressure.

[0050] In an optional embodiment, the pusher mechanism 3 can also be set at a suitable position on the bottom edge of the frame 11. At the same time, the width and height of the pusher mechanism 3 can be adjusted according to the actual situation to maximize the pushing of the grain and achieve layered pushing of the grain, reduce the difficulty of pushing the grain, and improve the clearing efficiency. Meanwhile, the projection width of the pusher mechanism 3 in the corresponding pushing direction can at least cover the track mechanism 12, which can prevent the grain from entering the frame 11 and the travel range of the track mechanism 12, effectively reducing the grain under the pressure of the track mechanism 12, and thus reducing the breakage rate of the grain under pressure.

[0051] The spiral conveyor mechanism 4 is used in conjunction with the walking mechanism 1 to move grain to a more distant location, achieving full coverage of grain transfer throughout the entire grain warehouse.

[0052] In one or more embodiments, the spiral conveying mechanism 4 includes at least two spiral conveying mechanisms 4, which are hinged to the frame 11. The spiral conveying mechanism 4 is connected to a drive cylinder 41, which drives the spiral conveying mechanism 4 to swing relative to the frame 11. Each of the at least two spiral conveying mechanisms 4 has at least one station within its swing range that can be aligned and connected to each other. This allows each spiral conveying mechanism 4 to be used independently or in combination to achieve the conveying of grain over different distances.

[0053] In an optional embodiment, one end of the spiral conveying mechanism 4 is hinged to the frame 11 and the other end is a free end. One end of the drive cylinder 41 is connected to the frame 11 and the other end is connected to a suitable position in the length direction of the spiral conveying mechanism 4, so that the spiral conveying mechanism 4 can swing relative to the frame 11 in the horizontal plane under the drive of the drive cylinder 41, thereby realizing the transfer of grain within the swing coverage area. When swinging close to the frame 11, the overall volume of the equipment can be reduced to facilitate the equipment to be moved into or out of the grain silo.

[0054] In an optional embodiment, the drive cylinder 41 may be a hydraulic cylinder, and the drive cylinder 41 is connected to the hydraulic control system of the control system.

[0055] In an optional embodiment, the spiral conveying mechanism 4 includes a mounting frame 42 and an auger mechanism 43. The auger mechanism 43 is disposed within the mounting frame 42, and the mounting frame 42 is connected to the vehicle frame 11 via a pivot 5. The mounting frame 42 can be a frame structure formed by welding together several horizontally, vertically, and three-dimensionally arranged rods, providing an installation position for the auger mechanism 43.

[0056] In an optional embodiment, the rotating shaft 5 can be set at a suitable position at both ends of the front end of the frame 11 in the direction of travel, so that the spiral transfer mechanism 4 can swing to be parallel to the side of the frame 11 in the length direction, or swing to be parallel to the front end of the frame 11 in the length direction. The two spiral transfer mechanisms 4 are arranged opposite to each other on both sides of the frame 11. When the spiral transfer mechanism 4 swings to be parallel to the front end of the frame 11 in the length direction, the two spiral transfer mechanisms 4 are connected to each other, so as to realize the superposition of the transfer distance.

[0057] In an optional embodiment, when the spiral conveying mechanism 4 swings to a state parallel to the side of the frame 11, the side of the mounting frame 42 closest to the frame 11 is set as a single plate-shaped structural member, and the auger mechanism 43 is set on the other side of the plate-shaped structural member. During the swinging process of the spiral conveying mechanism 4, the grain is restricted within the rotation range of the auger mechanism 43, and a grain conveying channel is formed between the auger mechanism 43 and the mounting frame 42, realizing long-distance grain conveying. Furthermore, the plate-shaped structural member can further push and gather the grain on the grain warehouse floor, improving the cleaning effect and efficiency.

[0058] In an optional embodiment, the mounting frame 42 may be fitted with a steel mesh on top of the auger mechanism 43, depending on the actual situation, to further limit the grain conveying channel range of the auger mechanism 43 within the mounting frame 42, thereby achieving smooth and safe grain conveying and improving the safety of equipment use.

[0059] In an optional embodiment, a steel mesh can be installed on the side of the frame 11 above the corresponding mounting frame 42 abutment position, so that the spiral conveying mechanism 4 is shielded by the steel mesh after approaching the frame 11, which can improve the overall safety of the equipment.

[0060] In an optional embodiment, the bottom of the mounting frame 42 is provided with several casters 6. This allows the spiral transfer mechanism 4 to move smoothly and stably along the ground during the swinging process, reducing the pressure on the frame 11 and allowing the spiral transfer mechanism 4 to be set longer.

[0061] In an optional embodiment, casters 6 are preferably provided at both ends of the mounting frame 42 along its length.

[0062] In an optional embodiment, the auger mechanism 43 includes a drive device 431 and a screw mechanism 432, which are drivenly connected. The drive device 431 is located at one end of the mounting frame 42. This allows each screw conveyor mechanism 4 to operate independently or in conjunction with others, adapting to the cleaning operation environment and improving the cleaning effect.

[0063] In an optional embodiment, a storage platform 16 adapted to the mounting frame 42 is provided on the frame 11. This facilitates the storage of the spiral conveyor mechanism 4 on the frame 11, reduces the size of the equipment, facilitates the movement of the equipment in and out of the grain silo, and improves the safety of equipment use.

[0064] In this embodiment, a grain storage cleaning device has an excavation mechanism 2 arranged side by side with the cab 13, a pusher mechanism 3 located at the front end of the frame 11 in the direction of travel, and two spiral conveying mechanisms 4 arranged opposite each other on the left and right sides of the frame 11. The rotating shafts 5 of the two spiral conveying mechanisms 4 are respectively located at appropriate positions at the front end of the frame 11. The two spiral conveying mechanisms 4 can swing horizontally within a range of 90°. When the two spiral conveying mechanisms 4 swing to the front end of the frame 11, the axes of the two spiral conveying mechanisms 4 are aligned and connected.

[0065] This embodiment of a grain storage cleaning device integrates multiple cleaning mechanisms on a chassis 11, achieving the integration of walking, digging, pushing, and spiral conveying functions. The rational arrangement of these mechanisms replaces traditional loader cleaning operations, enabling cleaning operations tailored to different grain storage conditions. This avoids manual cleaning, improves cleaning efficiency, and achieves automated, reduced-manpower, and cleaner cleaning operations. Specifically, the track mechanism 12 with a rubber outer layer 14 supports the walking frame, overcoming the problem of insufficient grip and slippage when the walking mechanism 1 is on the grain, and reducing the breakage rate of the grain upon contact. The digging mechanism 2 enables rapid... The system quickly clears the grain piled up behind the grain silo door, facilitating equipment entry for grain silo operations. The pusher mechanism 3 pushes the grain in front of the equipment's travel direction, reducing the amount of grain crushed during equipment movement, further lowering the breakage rate, and providing thrust to the grain to achieve the purpose of clearing the silo, reducing the difficulty of clearing and improving efficiency. The spiral conveyor mechanism 4 establishes a transport channel from the grain pile to the lower grain outlet, enabling smooth transport of grain from further away to the lower grain outlet. Multiple spiral conveyor mechanisms 4 work together to achieve full coverage transport of grain within the silo, resulting in better clearing effects, higher equipment utilization, and reduced investment in grain silo clearing equipment.

[0066] Example 2 A grain warehouse cleaning method, employing a grain warehouse cleaning device as described in Example 1, includes the following steps: S1. Move the grain storage equipment to the outside of the grain storage door, and use the digging and pulling mechanism 2 to remove and transfer the grain behind the grain storage door to the grain outlet; S2. The mobile grain warehouse cleaning equipment enters the grain warehouse. During the movement, the pusher mechanism 3 pushes out the travel channel in front of the frame 11 in the direction of travel. By adjusting the unfolding state of the spiral conveying mechanism 4, the grain on the side of the frame 11 is transported to the grain outlet. S3. Move the grain warehouse cleaning equipment along the walking path; S4, repeat S2-S3 until the inventory is cleared.

[0067] This embodiment of a grain warehouse cleaning method utilizes multiple functional cleaning mechanisms working together to achieve efficient and low-breakage grain cleaning operations within the grain warehouse. The digging and pulling mechanism 2 can dig, pull, and move grain from hard-to-clean locations such as behind the grain warehouse door and at the corners of the grain warehouse. The pushing mechanism 3 can push, layer, or sweep the grain in front of the equipment's travel direction. The spiral conveying mechanism 4 can guide and transport grain to suitable areas. Through the cooperation of the digging and pulling mechanism 2, the pushing mechanism 3, and the spiral conveying mechanism 4, the grain within the grain warehouse can be fully transferred. At the same time, the area covered by the traveling mechanism 1 can be automatically cleared in advance, reducing the amount of grain crushed by the equipment. Combined with the rubber track mechanism 12, the grain crushing rate can be minimized.
