Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, and in particular to an automatic material cleaning device. Background Technology

[0002] In the material handling and transfer processes of industrial production workshops, mobile trolleys, as common material carrying and transfer equipment, are crucial to production efficiency due to their stable operation. However, a common problem in workshops is material accumulation at the bottom of mobile trolleys. When the trolley moves back and forth above the hopper, material easily accumulates at its bottom. This accumulated material constantly rubs against the equipment surface, significantly accelerating wear and tear on the bottom of the trolley, the hopper, and related ground equipment, leading to frequent mechanical failures. Frequent failures not only greatly shorten the equipment's lifespan but also significantly increase the frequency of maintenance and parts replacement, resulting in high costs that place a heavy economic burden on enterprises.

[0003] Existing cleaning devices are difficult to store when not in use, occupying space at the bottom of the mobile trolley and easily colliding with other equipment, thus hindering the relocation or maintenance of the mobile trolley and causing inconvenience to production operations. Traditional manual cleaning requires a lot of physical labor, and a single cleaning session can take several hours, during which the equipment must be shut down, resulting in a significant reduction in effective operating time and severely slowing down production progress. In addition, the cleaning process usually requires multiple people to work together, which not only consumes a lot of human resources and wastes human resources, but also further exacerbates the problem of manpower shortage in the production process.

[0004] Therefore, there is an urgent need to develop an automatic material cleaning device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic material cleaning device that can automatically clean the accumulated material at the bottom of the mobile trolley, reduce the wear and tear on the mobile trolley and related equipment, reduce the frequency of mechanical failures, extend the service life of the equipment, improve material cleaning efficiency, ensure the continuity of production, improve the utilization efficiency of human resources, and at the same time, it aims to solve the problem that existing cleaning devices are easily damaged and occupy space when not in operation, which causes inconvenience to production operations.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An automatic cleaning device includes a mounting component, a fixing component, and a cleaning component. The mounting component is fixedly connected to the vehicle body, and the cleaning component is rotatably connected to the mounting component. The angle between the cleaning component and the forward direction of the vehicle body is denoted as α. The mounting component can abut against the rear side of the cleaning component such that 90° < α < 180°. The fixing component is fixedly connected to the vehicle body and detachably connected to the cleaning component. When the fixing component is connected to the cleaning component, the distance between the bottom of the cleaning component and the ground is not less than 10cm.

[0008] In some optional embodiments, the cleaning component includes a scraper and a rotating shaft connected together, and the mounting component includes a connecting portion connected to both sides of the vehicle body, the connecting portion having a corresponding mounting hole, and the rotating shaft rotatably passing through the mounting hole.

[0009] In some alternative embodiments, the mounting component is provided with a bearing, and the rotating shaft is rotatably engaged with the mounting component via the bearing.

[0010] In some optional embodiments, the mounting component further includes an abutment portion, the two ends of which are respectively connected to the connecting portion, and the abutment portion is located below the rotating shaft for abutting against the rear side of the scraper.

[0011] In some optional embodiments, baffles are provided on both sides of the hopper, the lower end of the scraper is located between the baffles, and both sides of the scraper are in contact with the corresponding side baffles.

[0012] In some alternative embodiments, the fastener includes a chain and a hook, one end of the chain being connected to the vehicle body and the other end to the hook, and the scraper having a lug for attaching to the lug.

[0013] In some alternative embodiments, the automatic cleaning device further includes an extension plate protruding from the front side of the vehicle body, and the chain is connected to the extension plate.

[0014] In some alternative embodiments, the scraper is also provided with a handle.

[0015] In some alternative embodiments, when the rear side of the cleaning component abuts against the mounting component, the lower end of the cleaning component overlaps the ground.

[0016] In some alternative embodiments, when the rear side of the cleaning member abuts against the mounting member, 95°≤α≤135°.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides an automatic cleaning device, including a mounting component, a fixing component, and a cleaning component. The mounting component is fixedly connected to the vehicle body, and the cleaning component is rotatably connected to the mounting component. The angle between the cleaning component and the forward direction of the vehicle body is denoted as α. The mounting component can abut against the rear side of the cleaning component, such that 90° < α < 180°. The fixing component is fixedly connected to the vehicle body and detachably connected to the cleaning component. When the fixing component is connected to the cleaning component, the distance between the bottom of the cleaning component and the ground is not less than 10cm. In the non-working state, the fixing component is connected to the cleaning component, ensuring that the distance between the bottom of the cleaning component and the ground is not less than 10cm, thus enabling the cleaning component to be stored, preventing it from occupying space under the vehicle body, preventing collisions between the cleaning component and other equipment, and facilitating the transfer or maintenance of the vehicle body. In operation, the fixing component and the cleaning component are separated. The cleaning component naturally hangs down to the working position under its own weight. When the vehicle moves forward, the rear side of the cleaning component abuts against the mounting component, forming a forward tilt angle α. The forward-tilting cleaning component pushes the accumulated material into the hopper. When the vehicle moves backward, the cleaning component automatically rotates upward due to the reaction force of the accumulated material, preventing the material from being pushed away from the hopper. This forms an adaptive mechanism of "forward pushing and backward obstacle avoidance," requiring no additional power drive and relying entirely on the movement of the vehicle to achieve automatic material cleaning. This reduces wear and tear on the mobile trolley and related equipment, lowers the frequency of mechanical failures, and extends the service life of the equipment. It also improves material cleaning efficiency, ensures production continuity, and enhances the utilization efficiency of human resources. Furthermore, the detachable connection between the fixing component and the cleaning component allows the cleaning component to be stored away when not in operation, preventing damage from collisions with other equipment. This facilitates the transfer or maintenance of the mobile trolley, ensuring smooth production operations. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0024] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0027] like Figure 1 As shown, this embodiment provides an automatic cleaning device, including a mounting component 1, a fixing component 2, and a cleaning component 3. The mounting component 1 is fixedly connected to the vehicle body 100, and the cleaning component 3 is rotatably connected to the mounting component 1. The angle between the cleaning component 3 and the forward direction of the vehicle body 100 is denoted as α. The mounting component 1 can abut against the rear side of the cleaning component 3 such that 90° < α < 180°. The fixing component 2 is fixedly connected to the vehicle body 100 and detachably connected to the cleaning component 3. When the fixing component 2 is connected to the cleaning component 3, the distance between the bottom of the cleaning component 3 and the ground is not less than 10cm. The forward direction of the vehicle body 100 is as follows... Figure 1 As indicated by the middle arrow.

[0028] In the non-working state, the fixing part 2 is connected to the cleaning part 3, ensuring that the bottom of the cleaning part 3 is at least 10cm from the ground. This allows for the storage of the cleaning part 3, preventing it from occupying the bottom space of the vehicle body 100, avoiding collisions with other equipment, and facilitating the relocation or maintenance of the vehicle body 100. In the working state, the fixing part 2 is separated from the cleaning part 3, which naturally hangs down to the working position under its own weight. When the vehicle body 100 moves forward, the rear side of the cleaning part 3 abuts against the mounting part 1, forming a forward tilt angle α. The forward-tilted cleaning part 3 can push the accumulated material into the hopper 200. When the vehicle body 100 moves backward, the cleaning part 3 is automatically rotated upward by the reaction force of the accumulated material, preventing the material from being pushed away from the hopper 200. This forms an adaptive mechanism of "forward pushing and backward obstacle avoidance," requiring no additional power drive and relying entirely on the movement of the vehicle body 100 to achieve automatic material cleaning.

[0029] By employing the automatic cleaning device of this embodiment, accumulated material at the bottom of the mobile trolley can be automatically cleaned, reducing wear and tear on the mobile trolley and related equipment, lowering the frequency of mechanical failures, and extending the service life of the equipment; it also improves cleaning efficiency, ensuring production continuity and increasing the utilization efficiency of human resources. Furthermore, the detachable connection between the fixing component 2 and the cleaning component 3 allows the cleaning component 3 to be stored away when not in operation, preventing it from colliding with other equipment and causing damage, facilitating the transfer or maintenance of the mobile trolley, and ensuring smooth production operations.

[0030] In some optional embodiments, the cleaning component 3 includes a scraper 31 and a rotating shaft 32 connected together. The mounting component 1 includes connecting parts 11 connected to both sides of the vehicle body 100. The connecting parts 11 are provided with corresponding mounting holes, and the rotating shaft 32 is rotatably inserted through the mounting holes. This eliminates the need for complex connection structures, making the installation simple and efficient. It facilitates retrofitting existing mobile carts and helps reduce production costs. Furthermore, this structural design does not occupy excessive space. The connecting parts 11 are directly connected to both sides of the vehicle body 100, exhibiting high integration with the vehicle body 100 and not interfering with the normal operation of the mobile cart, thus ensuring the stability and smoothness of the mobile cart during material transfer.

[0031] In other embodiments, the mounting component 1 is provided with a bearing, and the rotating shaft 32 is rotatably engaged with the mounting component 1 through the bearing, which effectively improves the smoothness of the rotation of the rotating shaft 32, helps to reduce the resistance encountered when the cleaning component 3 rotates upward, and can reduce the operational difficulty of storing the cleaning component 3.

[0032] In some optional embodiments, the mounting component 1 further includes an abutment portion 12, with both ends of the abutment portion 12 connected to the connecting portion 11, and the abutment portion 12 is located below the rotating shaft 32 for abutting against the rear side of the scraper 31 to limit the angle α range between the sweeping component 3 and the forward direction of the trolley. When the trolley moves forward, it abuts against the sweeping component 3 to provide a thrust for cleaning up accumulated material, and when the trolley moves backward, it allows the sweeping component 3 to rotate upward to achieve automatic avoidance.

[0033] In some optional embodiments, the feed inlet of the hopper 200 is located on the ground along the trolley's forward path, and baffles 300 are provided on both sides of the hopper 200. The lower end of the scraper 31 is located between the baffles 300, and both sides of the scraper 31 are in contact with the corresponding side baffles 300. The baffles 300 provide axial restraint for the cleaning component 3, effectively preventing the scraper 31 from shifting to the sides of the hopper 200, ensuring that the scraper 31 always runs on the preset cleaning path, avoiding deviation of the cleaning position due to displacement, thereby ensuring the stability and reliability of the cleaning work. At the same time, the contact between the scraper 31 and the corresponding side baffles 300 on both sides allows the scraper 31 to accurately cover the area above the hopper 200 that needs to be cleaned, avoiding the problem of material accumulation and leakage on the upper edges of the hopper 200 due to the scraper 31 being too short relative to the width of the hopper 200 or displacement, ensuring that the accumulated material above the hopper 200 can be completely removed, reducing the risk of wear and tear on the equipment caused by material residue.

[0034] In some optional embodiments, the fixing component 2 includes a chain 21 and a hook 22. One end of the chain 21 is connected to the vehicle body 100, and the other end is connected to the hook 22. The scraper 31 is provided with a hanging ear 4, and the hook 22 can be hooked onto the hanging ear 4. The cooperation between the chain 21 and the hook 22 provides a stable fixing method for the scraper 31. When the scraper 31 is not in working state, simply hooking the hook 22 onto the hanging ear 4 of the scraper 31 will firmly fix the scraper 31 to the vehicle body 100 through the pulling action of the chain 21. This effectively prevents the scraper 31 from shaking randomly due to its own weight or equipment vibration, prevents the scraper 31 from colliding with other components and causing damage, and also prevents the scraper 31 from drooping and interfering with the operation of the mobile trolley. Furthermore, the hook-and-hanging structure of the hook 22 and the hanging ear 4 is simple and intuitive. Operators do not need to use tools and can quickly complete the storage and fixing or release and unfolding of the scraper 31 by manual operation, which improves the operating efficiency and shortens the time for the scraper 31 to switch working states. In addition, since the chain 21 can be flexibly bent, when the scraper 31 has slight differences in its own structure or installation position, the chain 21 can ensure that the hook 22 and the lug 4 are precisely connected through appropriate deformation, which enhances the compatibility and fault tolerance of the fixed structure.

[0035] In some optional embodiments, the automatic cleaning device further includes an extension plate 5, which protrudes from the front side of the vehicle body 100, and the chain 21 is connected to the extension plate 5. The extension plate 5 extends the connection point of the chain 21 forward to the front side of the vehicle body 100, making the stress point of the chain 21 closer to the suspension position of the scraper 31 in space, forming a more reasonable force transmission path. When the chain 21 pulls the scraper 31 to achieve storage and fixation, the line of action of the tension can be closer to the vertical line of the center of gravity of the scraper 31, avoiding the generation of additional torque due to excessive deviation between the stress point and the center of gravity, thereby reducing the local stress concentration phenomenon at the connection part 11 of the vehicle body 100 due to the action of torque. This design effectively reduces the structural load at the connection point between the vehicle body 100 and the chain 21, preventing deformation, cracking and other damage in this part due to stress concentration after long-term use, and extending the service life of the vehicle body 100 and the fastener 2.

[0036] In some optional embodiments, the scraper 31 is also provided with a handle 6, which provides a convenient gripping point for the operator. When it is necessary to adjust the position of the scraper 31, such as releasing the scraper 31 from the storage position, storing and fixing the scraper 31 from the working position, or when the scraper 31 becomes slightly stuck due to long-term use and needs to be manually reset, the handle 6 can transmit the operator's force to the scraper 31 more efficiently, avoiding force loss or operational difficulties caused by improper force application points, thereby improving operational efficiency, reducing physical exertion, and ensuring work safety.

[0037] In some optional embodiments, when the rear side of the cleaning component 3 abuts against the mounting component 1, the lower end of the cleaning component 3 overlaps the ground, forming a working posture in close contact with the ground. This posture ensures that the cleaning component 3 maintains contact with the ground as it moves with the trolley, preventing the cleaning component 3 from being suspended in the air or having an excessive gap with the ground, thus ensuring effective cleaning. Furthermore, the way the lower end of the cleaning component 3 overlaps the ground, compared to a rigid abutment, can buffer the impact force between the cleaning component 3 and the ground to a certain extent, reducing wear and tear on the ground and the cleaning component 3 itself caused by rigid contact, extending the service life of the cleaning component 3, and also reducing the risk of damage to the ground. In addition, the stable overlap prevents the cleaning component 3 from shaking or jumping during operation, preventing collisions between the cleaning component 3 and other equipment components caused by shaking, ensuring the overall safety of the equipment operation.

[0038] In some optional embodiments, when the rear side of the sweeping component 3 abuts against the mounting component 1, 95°≤α≤135°, so that the tilt angle of the sweeping component 3 is appropriate, the lateral scraping force on the ground is moderate, and the material can be pushed obliquely. The material is gathered forward by the power of the trolley's forward movement, making it easier to push the material into the hopper 200.

[0039] Optionally, α can be 95°, 105°, 120°, or 135°. The smaller the angle of α, the stronger the scraping force of the cleaning component 3 on the ground. The angle of α can be set adaptively according to the physical characteristics of the accumulated material, such as its mass and viscosity, and is not limited here.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
