Description

Technical Field

[0001] This utility model belongs to the field of grain machinery technology, specifically relating to a mobile cleaning machine suitable for elevated warehouses. Background Technology

[0002] The grain storage industry is currently accelerating its transformation towards large-scale and automated operations. However, as a crucial link in storage turnover, the clearing operation still faces triple technical barriers in terms of efficiency, environmental protection, and flexibility. Current mainstream clearing solutions mainly combine manual operation with traditional fixed equipment, such as a multi-stage operation mode using a grain unloader paired with a belt conveyor. These solutions have revealed a series of deep-seated problems in practical applications.

[0003] From the perspective of clearance efficiency, although traditional equipment combinations can partially replace manual labor, the material picking, conveying, and transfer processes rely on multiple levels of equipment relay. The disassembly and reinstallation of equipment is cumbersome, and the clearance process requires frequent relocation, resulting in low clearance efficiency.

[0004] In terms of equipment flexibility and scenario adaptability, traditional solutions also have significant shortcomings. Fixed or semi-fixed equipment relies on auxiliary machinery such as cranes and forklifts for handling. Transferring equipment from high-bay warehouses requires disassembly, hoisting, transportation, and reloading, which takes a long time for a single transfer and is difficult to meet the high-frequency needs of alternating operations in multiple warehouses. Utility Model Content

[0005] This utility model provides a mobile warehouse clearing machine suitable for elevated warehouses, aiming to improve the efficiency of warehouse clearing operations and the flexibility of alternating operations between multiple warehouses.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a mobile clearing machine suitable for elevated warehouses, comprising:

[0007] The clearing trolley is equipped with a transition hopper.

[0008] The material handling component is installed on the cleaning trolley and connected to the transition silo, and is used to collect the grain located below it into the transition silo;

[0009] The telescopic grain discharge assembly is installed on the cleaning trolley and connected to the bottom of the transition silo. The discharge port of the telescopic grain discharge assembly is used to align with the discharge port of the high-bay silo to discharge the grain into the discharge port.

[0010] The cleaning trolley is used to rotate around the discharge port in the elevated warehouse, and the telescopic grain discharge assembly is used to extend and retract as the distance between the cleaning trolley and the discharge port changes.

[0011] In one possible implementation, the retractable grain discharge component includes:

[0012] Trailers are used to travel within the overhead bins and are suitable for being secured to the discharge port.

[0013] A pneumatic silo is installed on the cleaning trolley and connected to the transition silo.

[0014] The telescopic pipe is connected to the pneumatic silo at one end and to the trailer at the other end, forming a discharge port. The discharge port is used to align with the discharge port when the trailer is fixed to the discharge port.

[0015] The telescopic pipe is used to extend and retract under the traction of a trailer and / or a clearing trolley, and the pneumatic hopper is used to receive grain from the transition hopper and blow the grain to the discharge port under positive pressure through the telescopic pipe.

[0016] In some embodiments, the trailer is equipped with a positioning linkage mechanism, which is used to fix the grain discharge port to the inlet and outlet channel of the elevated warehouse when the grain discharge port is aligned with the material drop port.

[0017] For example, a pneumatic silo includes:

[0018] The silo body is fixed to the cleaning trolley and connected to the transition silo via a closed-loop unloading valve;

[0019] The blower is installed on the clearing trolley and connected to the warehouse body. The blower's outlet and the telescopic pipe are positioned opposite each other and both are connected to the warehouse body.

[0020] For example, the expansion joint includes multiple pipe sections, with adjacent pipe sections connected by a rotary joint.

[0021] In some embodiments, the rotary joint closest to the second end has 360 degrees of rotational freedom, and the other rotary joints are provided with limiting mechanisms to limit their rotation angle range.

[0022] For example, the material handling component includes:

[0023] The chain bucket reclaimer is hinged at one end to the clearing trolley and used to discharge material toward the transition hopper, while the other end extends downward at an angle to extract grain below it.

[0024] The telescopic drive component is hinged at one end to the clearing trolley and at the other end to the middle of the chain bucket reclaimer, and is used to drive the chain bucket reclaimer to swing up and down.

[0025] In one possible implementation, the mobile clearing machine for elevated warehouses also includes a dust collector; the material handling assembly is covered with a dust collector cover, and both the dust collector cover and the telescopic grain discharge assembly are connected to the dust collector via dust collection pipes.

[0026] In some embodiments, the mobile clearing machine suitable for elevated warehouses also includes a mobile lifting vehicle, which is used to move between different elevated warehouses. The mobile lifting vehicle is equipped with a lifting platform, which is used to stop the clearing trolley and lift the clearing trolley to the entrance and exit passage of the elevated warehouse.

[0027] The advantages of the mobile cleaning machine for elevated warehouses provided by this utility model are as follows: Compared with the prior art, the mobile cleaning machine for elevated warehouses of this utility model integrates the material picking component and the telescopic grain discharge component on the cleaning trolley, thereby avoiding the disassembly and reassembly problems during the transfer process between different elevated warehouses. This not only helps to improve the cleaning efficiency of a single warehouse, but also improves the transfer flexibility and efficiency of alternating operations of multiple warehouses.

[0028] During the cleaning operation inside the elevated warehouse, the cleaning trolley rotates around the discharge port of the elevated warehouse, with the radius of rotation gradually increasing. This allows the material-collecting component to pass through various positions on the bottom of the elevated warehouse. As the radius of rotation of the cleaning trolley changes, the telescopic grain discharge component can extend or retract based on the change in distance between the cleaning trolley and the discharge port, ensuring that the discharge port of the telescopic grain discharge component is always aligned with the discharge port. This allows the transition silo to continuously transport the grain collected by the material-collecting component to the telescopic grain discharge component, which then discharges the grain into the discharge port. The cleaning process can be completed simply by the cleaning trolley moving along a preset variable-diameter rotation path. This not only improves cleaning efficiency but also facilitates the integration with a control system to achieve full automation of the cleaning operation. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0036] The grain storage industry is currently accelerating its transformation towards large-scale and automated operations, with elevated warehouses becoming one of the mainstream storage facilities due to their high space utilization and large storage capacity. However, as a crucial link in storage turnover, the clearing operation still faces multiple technical bottlenecks in terms of efficiency, equipment flexibility, and safety.

[0037] Currently, the mainstream grain clearing solutions mainly combine manual operation with traditional fixed equipment, such as a multi-stage operation mode using a grain unloader combined with a belt conveyor. This solution has revealed the following problems in practical applications:

[0038] Low efficiency and heavy reliance on manual labor in warehouse clearing: While traditional equipment combinations partially replace manual labor, the material handling, conveying, and transfer processes still rely on multiple stages of equipment relay, requiring frequent manual adjustments to the equipment's position. Taking a typical elevated warehouse as an example, during the clearing process, the unloader needs to be manually pushed along the warehouse floor more than ten times. Each adjustment requires two to three workers and takes approximately forty minutes. During this time, manual connection to the belt conveyor interface and calibration of the equipment's tilt angle are also necessary. According to industry statistics, manual equipment adjustments account for about 40% of the total operation time in a single warehouse clearing operation.

[0039] Insufficient flexibility and high labor costs in equipment relocation: Fixed or semi-fixed equipment relies on auxiliary machinery such as cranes and forklifts for handling. Transferring equipment from high-bay warehouses requires at least six steps, including "manual disassembly of equipment parts → hoisting to transport vehicles → transportation to the target warehouse → manual reassembly and debugging." Each relocation also requires the coordinated work of multiple workers. For multi-warehouse alternating operation scenarios, traditional solutions, due to the high number of manual steps involved, are unable to meet the demands of high-frequency relocation.

[0040] Dust pollution and explosion risks are prominent: During the traditional mechanical material handling process, the friction of grain particles and the operation of equipment will generate a large amount of dust. Actual measurement data shows that the dust concentration in the working area of ​​the warehouse is often as high as 1000mg / m³. Due to the lack of integrated dust removal system in traditional equipment, and the easy disturbance of dust accumulation when manually adjusting the equipment, dust is easy to accumulate in the top of the warehouse and other parts. When the concentration reaches the explosion limit and encounters a source of ignition, there is a serious risk of dust explosion.

[0041] Automation compatibility and safety deficiencies: Traditional equipment relies on manual operation and adjustment, making it impossible to interface with warehouse automation systems and hindering the planning and remote control of clearing routes; moreover, it lacks explosion-proof dust removal devices, and workers face occupational health risks such as pneumoconiosis when working in high-dust environments, which does not meet the safety operation standards of modern warehousing, which emphasizes "unmanned and minimally staffed" operations.

[0042] At its core, the fundamental flaws of existing technologies lie in their low integration and poor mobility, coupled with a high reliance on manual operation in critical processes. This results in "time-consuming manual adjustments, low relocation efficiency, and high safety risks" becoming common industry problems during the clearance process. Therefore, there is an urgent need for an integrated clearance equipment with automated mobility and minimal human intervention to simultaneously meet the industry's demands for efficient operation, flexible relocation, and safe production.

[0043] Please refer to the following: Figures 1 to 4 The present invention provides a mobile cleaning machine suitable for elevated warehouses. The mobile cleaning machine for elevated warehouses includes a cleaning trolley 10, a material handling assembly 30, and a telescopic grain discharge assembly 40. The cleaning trolley 10 is equipped with a transition hopper 20. The material handling assembly 30 is located on the cleaning trolley 10 and connected to the transition hopper 20, used to collect grain located below it into the transition hopper 20. The telescopic grain discharge assembly 40 is located on the cleaning trolley 10 and connected below the transition hopper 20. The discharge port of the telescopic grain discharge assembly 40 is used to align with the discharge port 700 of the elevated warehouse 70 to discharge grain into the discharge port 700. The cleaning trolley 10 rotates within the elevated warehouse 70 with a variable diameter centered on the discharge port 700, and the telescopic grain discharge assembly 40 extends and retracts as the distance between the cleaning trolley 10 and the discharge port 700 changes.

[0044] It should be noted that the clearing trolley 10 in this embodiment can be a conventional trolley that can move and steer flexibly, and as prior art, it will not be described in detail here. The material handling component 30 can suck the grain below it into the transition hopper 20 based on negative pressure suction, or it can scoop the grain below it into the transition hopper 20 based on a mechanical material handling structure, and there is no limitation here.

[0045] In this embodiment, the telescopic grain discharge component 40 can be understood as being able to flexibly extend or shorten to adapt to the change in distance between the clearing trolley 10 and the discharge port 700. Its extension and retraction can be achieved based on a curved and coiled pipe. The power for the grain to flow and be discharged from the telescopic grain discharge component 40 to the discharge port 700 can be driven by airflow or vibration. Here, airflow is preferred.

[0046] The working process of the mobile cleaning machine for elevated warehouses provided in this embodiment is as follows: the cleaning trolley 10 is placed on the outer platform of the elevated warehouse 70 by a lifting device. The cleaning trolley 10 moves on its own from the outer platform into the interior of the elevated warehouse 70 and stops near the discharge port 700. Then it rotates around the discharge port 700 as the center. During the rotation, the material picking component 30 collects the grain into the transition hopper 20. The transition hopper 20 discharges the grain into the telescopic grain discharge component 40, and then the discharge port of the telescopic grain discharge component 40 discharges the grain into the discharge port 700.

[0047] After rotating once, the cleaning trolley 10 moves away from the discharge port 700 to increase its turning radius. At this time, the telescopic grain discharge component 40 extends to adapt to the change in distance between the cleaning trolley 10 and the discharge port 700. Then the cleaning trolley 10 rotates around the discharge port 700 again. During the rotation, the grain at the position passed by the material picking component 30 is collected again and transported to the telescopic grain discharge component 40 and enters the discharge port 700. This process is repeated until the material picking component 30 passes through the bottom of the entire elevated warehouse 70.

[0048] It should be explained that the above working process applies to the case where the discharge port 700 is located at the center of the bottom of the overhead bin 70. If the discharge port 700 is located at or near the edge of the overhead bin 70, such as... Figure 1 As shown, during the clearing process, the clearing trolley 10 can make a half-circle rotation as needed.

[0049] After a single elevated warehouse 70 completes its cleaning operation, the cleaning trolley 10 returns to the external platform and is lowered back to the ground by a lifting device. Then, the cleaning trolley 10 moves on its own to the next elevated warehouse 70 that needs to be cleaned. The above process is repeated to achieve alternating cleaning operations for multiple warehouses. The transfer process does not require disassembly and reassembly, so it is suitable for high-frequency cleaning operations that require alternating multiple warehouses.

[0050] The mobile cleaning machine for elevated warehouses provided in this embodiment integrates the material picking component 30 and the telescopic grain discharge component 40 on the cleaning trolley 10, compared with the prior art. This avoids the disassembly and reassembly problems during the transfer process between different elevated warehouses 70 and the moving position of the cleaning machine. This not only helps to improve the cleaning efficiency of a single warehouse, but also improves the transfer flexibility and efficiency of alternating operations of multiple warehouses.

[0051] During the cleaning operation inside the elevated warehouse 70, the cleaning trolley 10 always rotates around the discharge port 700 of the elevated warehouse 70, and the radius of rotation gradually increases, so that the material picking component 30 can pass through various positions on the bottom of the elevated warehouse 70. When the radius of rotation of the cleaning trolley 10 changes, the telescopic grain discharge component 40 can extend and retract based on the change in distance between the cleaning trolley 10 and the discharge port 700, thereby ensuring that the discharge port of the telescopic grain discharge component 40 is always aligned with the discharge port 700. This allows the transition hopper 20 to continuously transport the grain collected by the material picking component 30 to the telescopic grain discharge component 40, which then discharges the grain into the discharge port 700. The cleaning process can be completed simply by the cleaning trolley 10 moving according to the preset variable diameter rotation path, which not only improves the cleaning efficiency, but also facilitates the complete automation of the cleaning operation when combined with a control system.

[0052] In some embodiments, see Figures 1 to 3 The telescopic grain discharge assembly 40 includes a trailer 41, a pneumatic hopper 42, and a telescopic pipe 43. The trailer 41 is used to travel within the elevated silo 70 and is adapted to be fixed at the discharge port 700. The pneumatic hopper 42 is disposed on the cleaning trolley 10 and connected to the transition silo 20. The first end of the telescopic pipe 43 is connected to the pneumatic hopper 42, and the second end is connected to the trailer 41 to form a grain discharge port. The grain discharge port is used to align with the discharge port 700 when the trailer 41 is fixed at the discharge port 700. The telescopic pipe 43 is used to extend and retract under the traction of the trailer 41 and / or the cleaning trolley 10. The pneumatic hopper 42 is used to receive grain from the transition silo 20 and blow the grain to the discharge port 700 with positive pressure through the telescopic pipe 43.

[0053] The pneumatic silo 42 can be understood as a silo with airflow propulsion. When the transition silo 20 transports grain to the pneumatic silo 42, it can enter the telescopic pipe 43 under the airflow propulsion. Then, it is continuously pushed into the discharge port 700 by the positive pressure propulsion within the telescopic pipe 43. The pneumatic silo 42 not only provides the transport power for the grain within the telescopic pipe 43, but also buffers the grain between the transition silo 20 and the telescopic pipe 43, thereby avoiding the problem of excessive flow of grain directly into the telescopic pipe 43 and causing pipe blockage.

[0054] In this embodiment, please refer to Figure 1 and Figure 3 The trailer 41 is equipped with a positioning linkage mechanism 411, which is used to fix the grain discharge port with the inlet and outlet channel of the elevated warehouse 70 when the grain discharge port is aligned with the material drop port 700.

[0055] The positioning linkage mechanism 411 can be two cross-hinged scissor structures, which use the forks at both ends to clamp the warehouse walls on both sides of the access channel of the elevated warehouse 70, thereby fixing the trailer 41 and preventing the discharge port of the telescopic pipe 43 from detaching from the discharge port 700 under the traction force of the cleaning trolley 10, thus improving the stability of the cleaning operation.

[0056] The positioning linkage mechanism 411 serves as the fixing structure of the trailer 41. Its structure can also adopt a foldable mechanical locking claw. The mechanical locking claw is used to lock the edge of the discharge port 700 to achieve precise fixing of the position of the trailer 41, thereby ensuring that the discharge port of the telescopic pipe 43 can always be aligned with the discharge port 700.

[0057] As one specific embodiment of the aforementioned pneumatic hopper 42, please refer to Figure 2 The pneumatic silo 42 includes a silo body 421 and a blower 423; wherein, the silo body 421 is fixed to the cleaning trolley 10 and connected to the transition silo 20 through a closed-loop unloading valve 422; the blower 423 is installed on the cleaning trolley 10 and connected to the silo body 421, and the air outlet of the blower 423 and the telescopic pipe 43 are arranged opposite to each other and both are connected to the silo body 421.

[0058] The transition hopper 20 directly transports the grain into the hopper body 421. The blower 423 blows air into the hopper body 421. Since the blower 423 and the telescopic pipe 43 are set opposite each other, the grain in the hopper body 421 will be carried into the telescopic pipe 43 by the airflow. The grain can also obtain airflow power in the telescopic pipe 43, thereby realizing the efficient transfer of grain from the pneumatic hopper 42 to the discharge port 700. Compared with the traditional screw conveyor method, it is not only more efficient, but also has a simple and compact structure.

[0059] The closed-loop discharge valve 422 is a commonly used valve structure for discharging powder and granular materials. It can prevent air leakage while completing the discharge. As it is existing technology, its air-closing principle will not be described in detail here. In this embodiment, the closed-loop discharge valve 422 is used mainly because there is a positive pressure airflow in the pneumatic silo 42. By setting the closed-loop discharge valve 422, the grain can fall smoothly from the transition silo 20 into the pneumatic silo 42, while preventing air leakage from the pneumatic silo 42 into the transition silo 20. This ensures the positive pressure in the pneumatic silo 42 and the stability of the positive pressure conveying airflow formed in the telescopic pipe 43.

[0060] For example, such as Figure 3As shown, the telescopic pipe 43 includes multiple pipe sections 431, and adjacent pipe sections 431 are connected by rotary joints 432; the rotary joint 432 closest to the second end has 360 degrees of rotational freedom, and the remaining rotary joints 432 are provided with limiting mechanisms 433 for limiting their rotation angle range.

[0061] Rotary joint 432 is a commonly used structural component for pipeline connection. Its detailed structure will not be described in detail here. Its purpose is to enable the two pipe sections 431 connected on both sides to swing relative to each other, thereby realizing the overall length expansion and contraction of the telescopic pipe 43 by folding and unfolding between the pipe sections 431.

[0062] To prevent the rotation angle of the rotary joint 432 between adjacent pipe sections 431 from being too large and affecting the smoothness of the overall telescopic movement, a limiting mechanism 433 is set on the rotary joint 432 to limit its rotation angle range, thereby improving the stability and smoothness of the telescopic movement.

[0063] The limiting mechanism 433 can be a limiting rod that is respectively set on two relatively rotating parts of the rotary joint 432, and the rotation is limited by the mutual abutment between the limiting rods.

[0064] Specifically, the limiting mechanism 433 limits the rotation angle range of adjacent pipe sections to 0°~180°.

[0065] Considering that the pipe section 431 closest to the second end needs to be stably aligned with the material discharge port 700, and that the telescopic pipe 43 needs to rotate with the movement of the cleaning trolley 10 during the cleaning operation, the rotary joint 432 connected to the end pipe section 431 has 360 degrees of rotational freedom, that is, the rotary joint 432 is not equipped with a limiting mechanism 433, thereby ensuring that the telescopic pipe 43 can smoothly follow the rotational movement trajectory of the cleaning trolley 10.

[0066] As one specific embodiment of the aforementioned material handling component 30, please refer to Figure 2 The material handling assembly 30 includes a chain bucket reclaimer 31 and a telescopic drive 32; one end of the chain bucket reclaimer 31 is hinged to the cleaning trolley 10 and is used to discharge material toward the transition hopper 20, and the other end extends downward at an angle and is used to extract grain below it; one end of the telescopic drive 32 is hinged to the cleaning trolley 10, and the other end is hinged to the middle of the chain bucket reclaimer 31, and is used to drive the chain bucket reclaimer 31 to swing up and down.

[0067] The chain bucket reclaimer 31 is a commonly used material reclaiming device in the warehousing field. Its structure is similar to a conveyor, and as it is existing technology, it will not be described in detail here. In this embodiment, the height of the reclaiming end of the chain bucket reclaimer 31 can be adjusted by the telescopic drive component 32, such as a hydraulic cylinder, which drives the chain bucket reclaimer 31 to swing up and down. This ensures that all the grain at the bottom of the high-bay warehouse 70 can be extracted into the transition warehouse 20, which helps to improve the cleanliness of the warehouse.

[0068] It should be noted that, to ensure the environmental friendliness of the clearance operation, please refer to [link / reference needed]. Figure 2 The aforementioned mobile warehouse cleaning machine for elevated warehouses also includes a dust collector 50; a dust collector hood 51 is installed on the material handling assembly 30, and both the dust collector hood 51 and the telescopic grain discharge assembly 40 are connected to the dust collector 50 via a dust collection pipe 52. Since the frequent stirring of grain during the material handling process easily generates dust, the dust collector hood 51 connected to the dust collector 50 can draw the dust generated during the material handling process into the dust collector 50. Simultaneously, the dust collector 50 is connected to the telescopic grain discharge assembly 40 via the dust collection pipe 52, which can draw dust generated during the grain discharge process into the dust collector 50, thereby ensuring the cleanliness and environmental friendliness of the warehouse cleaning operation.

[0069] For some possible implementations, please refer to [link / reference]. Figure 4 The mobile clearing machine suitable for elevated warehouses also includes a mobile lifting vehicle 60, which is used to move between different elevated warehouses 70. The mobile lifting vehicle 60 is equipped with a lifting platform, which is used to stop the clearing trolley 10 and lift the clearing trolley 10 to the entrance and exit passage of the elevated warehouse 70.

[0070] The mobile lifting platform 60, as a supporting peripheral device, can be a conventional scissor lift with casters. The mobile lifting platform 60 can be used to flexibly move the cleaning trolley 10 between different high-bay warehouses 70 to meet the needs of high-frequency cleaning operations with multiple warehouses alternating, thereby improving work efficiency.

[0071] Based on the above embodiments, the mobile clearing machine for elevated warehouses proposed in this application has the following driving mechanism for variable diameter rotary motion during clearing operations: When the front clearing trolley 10 (with a power source such as a battery) moves forward or backward, the rear trailer 41 is already limited at the entrance and exit passage of the elevated warehouse 70 by the positioning linkage mechanism 411, so the telescopic pipe 43 will automatically adapt to adjust its length by extending or retracting in a V-shape or in a straight line.

[0072] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
