[0001] The utility model relates to the technical field of lifting and feeding devices, and more specifically, to a lifting and feeding device and a mobile equipment for cleaning surface materials. Background Art

[0002] The transportation of coal is an indispensable part of life. As a high-capacity and efficient means of transportation, trains will inevitably leave a lot of coal on the inner wall of train carriages as coal is unloaded. These coal deposits not only occupy the space of the carriages, but also reduce the utilization rate of the carriages. Due to the limited space inside the carriages and the complex working environment, cleaning work becomes extremely difficult. Workers need to perform high-intensity physical labor in a limited space, facing the possible dust and harmful substances.

[0003] To solve the above problems, the prior art proposes to use negative pressure vacuuming or a push plate method, but the applicant has found obvious defects in actual application, that is, train transportation usually spans a large area and takes a long time, and the humidity in the train car may change during the transportation of coal. If the humidity rises, the coal dust may become sticky, especially the coal that is already piled up at the bottom, which has a certain viscosity with the car, and negative pressure may be difficult to adsorb, or it may easily cause the risk of blockage after adsorption. The push plate method still requires manual participation, and the degree of automation is not high.

[0020] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0021] 1. The device can automatically complete the collection, lifting and transportation of materials without manual intervention. That is, the shovel plate structure in the feeding mechanism is used to shovel the materials to the collection bin, and then the built-in transmission lifting mechanism is used to drive the hopper to circulate the shovel materials in the collection bin using the chain belt, and then the materials are transferred to the storage box for storage. Compared with the existing technology, it has a higher degree of automation, especially for the humidity changes and viscosity problems that may occur in the materials during transportation. This lifting and feeding device has obvious advantages and can further improve the cleanliness of cleaning.

[0022] In addition, the general inventive concept of the embodiment of the utility model adopts the method of lifting the material and using the gravitational potential energy of the lifted material for unloading. This design cleverly reduces the power source demand of the entire device. When the material is lifted to a certain height, its own gravitational potential energy can help the material slide smoothly along the discharge plate into the storage box. In this way, the device does not need to consume too much extra power during the unloading process, thereby achieving energy-saving effects. Secondly, since the material is lifted and then unloaded through the hopper, the storage box can be designed to have a certain depth. Such a design not only increases the volume of materials that can be collected by cleaning, but also improves the storage capacity of the device.

[0023] 2. The design of the hopper includes a mounting portion parallel to the ear plate and a curved and extended shoveling portion, which enables the hopper to remain stable during the lifting process, reducing the risk of the hopper falling off or shifting due to vibration or impact, thereby improving the transmission stability of the entire lifting and feeding device.

[0024] 3. The chain belt is wrapped around the driving shaft and the driven shaft. The driving shaft is the power source, and when the hydraulic motor is started, it drives the driving shaft to rotate. Since the outer circumference of the driving shaft is connected to the inner side of the chain belt, the rotation of the driving shaft will drive the chain belt to move. The other end of the chain belt is supported by the driven shaft, which is used to maintain the tension of the chain belt and ensure the stability of the entire transmission.

[0025] 4. The design of the plate chain sprocket makes the connection between the chain belt and the driving shaft and the driven shaft more stable. The engagement between the sprocket and the chain belt can reduce the slippage or deviation of the chain belt during the transmission process, thereby improving the stability and reliability of the entire transmission system. The symmetrical setting of the plate chain sprocket helps to evenly distribute the load on the chain belt.

[0026] 5. Each driving shaft bearing is equipped with at least two self-aligning ball bearings, which can effectively disperse the load and stress generated by the drive shaft during rotation. This helps to reduce the pressure on a single bearing, thereby improving the durability and reliability of the entire transmission system. At the same time, multiple self-aligning ball bearings can also provide automatic self-aligning functions at multiple points, further reducing misalignment problems caused by factors such as installation errors, temperature changes or workload changes. This design helps to reduce friction and wear between the bearing and the drive shaft and extend service life.

[0027] 6. The self-aligning ball bearing is equipped with a felt ring oil seal in the axial direction, an annular ring in the radial direction, and a bearing cover on one side of the active shaft bearing to ensure the reliability of the bearing under high dust conditions.

[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] like Figure 1 to Figure 2 The utility model provides a lifting and feeding device, including a lifting transmission mechanism 100, and a feeding mechanism 200 and a storage mechanism 300 respectively located on both sides of the lifting transmission mechanism 100.

[0044] Specifically, the lifting transmission mechanism 100 is used to drive the lifting of materials from a low place to a high place. The feeding mechanism 200 is located on one side of the lifting transmission mechanism 100 to stably convey the materials to be lifted to the lifting transmission mechanism 200, and the storage mechanism 300 is located on the other side of the lifting transmission mechanism 100 to receive and store the materials lifted from the lifting transmission mechanism.

[0045] In a specific scheme, the lifting transmission mechanism 100 includes a chain belt 101 arranged in the vertical direction and capable of being driven clockwise or counterclockwise, and a plurality of spaced hoppers 1 connected to the chain belt 101; the feeding mechanism 200 includes a shovel plate structure 201 and a collection bin 202 connected to the shovel plate structure 201; the storage mechanism 300 is arranged on the side of the lifting transmission mechanism 100 away from the shovel plate structure 201, including an inclined discharge plate 301, and a storage box 302 connected to the discharge plate 302.

[0046] It can be understood that the chain belt 101 is arranged in the vertical direction for lifting materials. The hopper 1 is connected to the chain belt 101 for loading and transporting materials. The size, shape and spacing of the hopper are reasonably designed according to the material characteristics and handling capacity to ensure that the material can enter and exit smoothly and avoid jamming or overflow. The shovel plate structure 201 is used to shovel the material into the collection bin 202, and the collection bin 202 temporarily stores the material and waits to be lifted by the hopper 1 of the lifting transmission mechanism 100. The storage mechanism 300 is arranged on the side of the lifting transmission mechanism away from the shovel plate structure, including an inclined discharge plate 301 and a storage box 302 connected to the discharge plate 301. The discharge plate 301 is set to have a preset inclination angle with the horizontal so that the material can slide smoothly into the storage box. At the same time, the surface of the discharge plate should be smooth to reduce the resistance of the material during the sliding process. The storage box 302 is used to store materials for centralized processing.

[0047] In a general inventive concept based on the above structure, the collection bin 202 is arranged at the bottom of the lifting transmission mechanism 100, and the hopper 1 is flipped during the transmission of the chain belt 101 to collect and lift the materials in the collection bin 202 and dump them onto the discharge plate 301, and the discharge plate 301 places the materials in the storage box 302.

[0048] The chain belt 101 can be driven clockwise or counterclockwise in the vertical direction. The chain belt is connected to a plurality of hoppers 1 arranged at intervals, which are responsible for lifting and transferring materials. The hoppers 1 are open and tilted in a preset direction. Such a design enables the hoppers to perform different functions at different positions of the chain belt.

[0049] Specifically, when the hopper 1 is located on the left side of the chain belt 101 (assuming that the left side is close to the aggregate bin), its opening is set obliquely upward. This inclination angle allows the hopper to effectively support the material like a shovel when passing through the aggregate bin and to lift it up stably. With the transmission of the chain belt, the hopper moves to the right side of the chain belt (assuming that the right side is away from the aggregate bin and close to the discharge plate). In this process, the hopper flips due to the movement of the chain belt, and its opening changes from obliquely upward to obliquely downward. This flipping action allows the material in the hopper to be smoothly dumped onto the discharge plate, thereby completing the transfer of the material; and when the hopper 1 is located at the bottom of the chain belt 101, the material in the aggregate bin (202) can be effectively shoveled up when the hopper 1 passes by.

[0050] Further, since the discharge plate 301 is tilted, its function is to receive the material poured from the hopper 1 and guide it to the storage box 302. The storage box 302 is responsible for storing the material that slides down from the discharge plate to ensure that the material can be collected safely and orderly.

[0051] In summary, the lifting and feeding device provided by the embodiment of the utility model is mainly used for automatic cleaning of materials, especially for the application scenarios of materials such as coal and slag in the transport compartment. The device can automatically complete the collection, lifting and transportation of materials without manual intervention. That is, the shovel plate structure 201 in the feeding mechanism 200 is used to shovel materials to the collection bin 202, and then through its built-in transmission lifting mechanism 100, the chain belt 101 is used to drive the hopper 1 to circulate and shovel materials in the collection bin 202, and then the materials are transferred to the storage box 302 for storage. Compared with the existing technology, it has a higher degree of automation, especially for the humidity changes and viscosity problems that may occur in the materials during transportation. The lifting and feeding device has obvious advantages and can further improve the cleanliness of cleaning.

[0052] In addition, the general inventive concept of the embodiment of the utility model adopts a method of lifting the material, and uses the gravitational potential energy of the lifted material to unload. This design cleverly reduces the power source demand of the entire device. When the material is lifted to a certain height, its own gravitational potential energy can help the material slide smoothly along the discharge plate 301 into the storage box 302. In this way, the device does not need to consume too much extra power during the unloading process, thereby achieving energy-saving effects. Secondly, since the material is lifted and then turned over and unloaded through the hopper 1, the storage box 302 can be designed to have a certain depth. Such a design not only increases the volume of materials that can be collected by cleaning, but also improves the storage capacity of the device.

[0053] In view of the above general inventive concept, the present utility model proposes a specific embodiment:

[0054] like Figure 3As shown, the shovel plate structure 201 is arranged to be inclined relative to the surface to be cleaned, more specifically, it forms an obtuse angle with the moving direction of the lifting and feeding device. The design is that when the device is moving, the shovel plate structure 201 can effectively push the material on the surface to be cleaned toward the collection bin 202 along its inclined direction.

[0055] Furthermore, the material collection bin 202 is designed as a concave "U-shaped" structure, and one end is connected to the shovel plate structure 201. The movement trajectory of the hopper 1 is matched to ensure that the hopper 1 can smoothly shovel the corresponding materials in the material collection bin during the movement. When the hopper 1 is located at the bottom of the chain belt 101, the direction of its opening should be opposite to the direction of material movement. This design helps the hopper to shovel materials more effectively and prevents materials from slipping during the shoveling process, thereby improving the working efficiency of the entire system.

[0056] Continue reading Figures 4 to 6 In one connection mode between the lifting transmission mechanism 100 and the hopper 1, a plurality of ear plates 2 are provided on the chain belt 101, and the ear plates 2 are connected to the chain belt 101 and are arranged in a direction perpendicular to the chain belt 101. When the chain belt 101 moves along a predetermined trajectory, the ear plates 2 are driven to move together. The hopper 1 includes a mounting portion 1a and a shoveling portion 1b. The mounting portion 1a is used as the connecting portion between the hopper 1 and the ear plates 2. The mounting portion 1a is arranged parallel to the ear plates 2 to ensure that the hopper can be stably mounted on the ear plates 2. The shoveling portion 1b is a portion extending from the mounting portion 1a in a direction away from the chain belt 101, so that the material can be effectively shoveled when the hopper moves. When the chain belt 101 drives the ear plates 2 and the hopper 1 to move, the shoveling portion 1b will first contact the material on the surface to be cleaned and shovel it.

[0057] Continue reading Figures 6 to 8 A driving member 102 is provided at one end of the chain belt 101 in the vertical direction, and the driving member 102 includes a driving motor 14, an active shaft bearing 8 and a driving shaft 17 connected to the active shaft bearing 8; the output shaft of the driving motor 14 is connected to the driving shaft 17 to drive the driving shaft 17 to rotate; a driven shaft bearing 15 is provided at one end of the chain belt 101 away from the driving member 102 in the height direction, and a driven shaft 18 is installed between the driven shaft bearings 15; the outer circumferential surfaces of the driving shaft 17 and the driven shaft 18 are both transmission-connected to the inner side surface of the chain belt 101.

[0058] It can be understood that the drive motor 14 is used as a power source, and its output shaft is connected to the drive shaft 17. When the drive motor 14 is working, it will provide rotational power to the drive shaft 17 through its output shaft. The driving shaft bearing 8 supports the drive shaft 17 to ensure that it works stably during the rotation process. Similar to the driving shaft bearing 8, the driven shaft bearing 15 supports the driven shaft 18 to ensure that it works stably during the movement of the chain belt 101. And the driven shaft 18 is not directly driven by an external power source, but is driven by the drive shaft 17 through the chain belt 101 to rotate. The chain belt is wrapped around the drive shaft 17 and the driven shaft 18. The driven shaft 18 is used to maintain the tension of the chain belt 101 and ensure the stability of the entire transmission. In short, when the hydraulic motor 14 is started, the hydraulic motor 14 drives the drive shaft 17 to rotate. Since the outer peripheral surface of the drive shaft 17 is connected to the inner side of the chain belt 101, the rotation of the drive shaft 17 will drive the chain belt 101 to move. The other end of the chain belt 101 is supported by a driven shaft 18 , and the driven shaft 18 rotates with the movement of the chain belt 101 , thereby realizing the movement of the hopper 1 .

[0059] Furthermore, two symmetrically arranged plate chain sprockets 4 are installed on the outer peripheries of the driven shaft 18 and the driving shaft 17 , and the plate chain sprockets 4 are connected to the chain belts 101 at corresponding positions.

[0060] Specifically, when the drive shaft 17 is driven to rotate by the hydraulic motor 14, the plate chain sprocket 4 on the drive shaft will rotate accordingly. These rotating sprockets transmit the rotational power to the chain belt 101 by meshing with the chain belt 101, causing it to start moving. The driven shaft 18 and the drive shaft 17 are arranged to better cooperate with the chain belt 101 through the arrangement of the plate chain sprocket 4 to ensure the stability and efficiency of power transmission. The symmetrically arranged plate chain sprocket 4 can balance the tension of the chain belt 101 to prevent the chain belt 101 from being deflected or loosened during operation.

[0061] Continue reading Figure 7 as well as Figure 8 , further, at least two self-aligning ball bearings 10 are installed in each driving shaft bearing 8, and the inner wall of the driving shaft bearing 8 is connected to the driving shaft 17 through the self-aligning ball bearings 10;

[0062] It can be understood that at least two self-aligning ball bearings 10 are installed in each driving shaft bearing 8, which can effectively disperse the load and stress generated by the driving shaft 17 during rotation. This helps to reduce the pressure on a single bearing, thereby improving the durability and reliability of the entire transmission system. At the same time, multiple self-aligning ball bearings 10 can also provide automatic self-aligning functions at multiple points, further reducing misalignment problems caused by factors such as installation errors, temperature changes or workload changes. This design helps to reduce friction and wear between the bearing and the driving shaft, and extend the service life.

[0063] Furthermore, a hole retaining ring 9 is provided between the self-aligning ball bearings 10 of each active shaft bearing 8, which mainly serves to space the self-aligning ball bearings 10, that is, to ensure that the self-aligning ball bearings 10 maintain an appropriate spacing in the active shaft bearing 8, and prevent the self-aligning ball bearings 10 from colliding or rubbing against each other during operation. At the same time, the hole retaining ring 9 can also help fix and locate the position of the self-aligning ball bearings 10, and prevent them from being displaced or falling off when the drive shaft 17 rotates. This stable layout helps to maintain the stability and accuracy of the transmission system.

[0064] In the embodiment of the utility model, a bearing cover 5 is installed on one side of the active shaft bearing 8, a felt ring oil seal 6 is installed axially on the self-aligning ball bearing 10, and an annular ring 7 is arranged radially to ensure the reliability of the bearing under high dust. The bearing cover 5 provides protection to prevent external impurities such as dust and moisture from entering the interior of the active shaft bearing 8, which helps to keep the bearing clean and in normal working condition. At the same time, the bearing cover 5 also helps to maintain the working condition inside the bearing and prevent leakage of its internal medium (such as lubricating medium). The felt ring oil seal 6 is used for axial sealing, and can also prevent dust and prevent external materials from entering the interior of the bearing. The arrangement of the annular ring 7 provides additional protection and support for the bearing in the radial direction. The annular ring 7 can enhance the overall strength of the bearing and improve the stability of the bearing when it is subjected to radial loads. At the same time, the annular ring 7 can also prevent materials in the radial direction from entering the interior of the bearing.

[0065] The driving member 102 includes a motor mounting seat 12 fixedly mounted on the side of the storage box 302, the surface of the motor mounting seat 12 is fixedly connected to the driving motor 14, and a coupling 13 is arranged in the motor mounting seat 12, and the output shaft end of the driving motor 14 is connected to the driving shaft 17 through the coupling 13. The motor mounting seat 12 is used to provide a mounting base to fix the driving motor 14 and ensure its stability during operation. The coupling 13 connects the output shaft end of the driving motor 14 with the driving shaft 17. The power is smoothly and effectively transmitted from the driving motor 14 to the driving shaft 17, and the slight misalignment between the two shafts (i.e., the output shaft and the driving shaft 17) can be compensated, vibration and impact are absorbed, and the angular deviation and axial displacement between the shafts are allowed to a certain extent.

[0066] The lifting and feeding device includes a tensioning component 16 , which is connected to the driven shaft bearing 15 , and the tensioning component 16 is threadedly connected to the material storage box 302 .

[0067] In the embodiment of the utility model, the tensioning component 16 is mainly used to adjust the tightness of the chain belt 101. Its specific structure is not limited and it can be a spiral tensioner or a spring tensioner.

[0068] In summary, the lifting and feeding device provided by the embodiment of the utility model is mainly suitable for cleaning solid materials. When the lifting and feeding device is working, the driving motor 14 drives the active shaft to rotate, and finally drives the chain belt 101 to rotate clockwise. At this time, a group of hoppers 1 connected to the chain belt 101 circulate, and the material brought out by the hopper 1 is finally sent to the storage box 302 and collected by the storage box 302.

[0069] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
