Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a device for cleaning up leftover materials in a carriage. Background Technology

[0002] During the transportation of coal by train or box truck, there is often residual material at the bottom of the carriage that needs to be cleaned manually, which is labor-intensive and inefficient.

[0003] Currently, there are many devices specifically designed for cleaning and suctioning leftover materials in train carriages. For example, patent application number CN202111547399.1 discloses a leftover material cleaning and suction device for train carriages, which includes a box for cleaning operations inside the carriage. The box is equipped with an adsorption mechanism and a suction nozzle assembly. The box contains a collection chamber, and the bottom of the collection chamber has a downward-opening unloading door, through which material is unloaded directly below the collection chamber. This unloading structure has the problem of inconvenient unloading, making it difficult to achieve simultaneous unloading during the cleaning and collection process. In addition, it is necessary to move the equipment before unloading or use additional collection facilities to receive the unloaded material. Utility Model Content

[0004] This application provides a vehicle cargo compartment waste material cleaning device that can achieve side unloading by using a spiral conveyor shaft, making unloading more convenient.

[0005] This application provides a vehicle cargo waste cleaning device, including a main frame, with guide mechanisms symmetrically arranged on the left and right sides of the main frame, a milling roller arranged on the lower part of the main frame near the front, a suction cylinder arranged at the bottom of the main frame, a material holding box arranged in the middle of the main frame, and a fan installed above the material holding box. The fan and the suction cylinder work together to suck the waste material in the vehicle cargo into the material holding box. The material holding box is V-shaped, and a spiral conveying shaft is arranged at the bottom of the material holding box. A discharge port is opened on the left or right side of the bottom of the material holding box for unloading through the spiral conveying shaft. A plug is installed on the discharge port.

[0006] In one possible implementation, there are four guiding mechanisms, which are symmetrically distributed at the four corners of the main frame. Each guiding mechanism includes a guide bracket capable of tilting up and down, and a horizontal guide wheel and a vertical guide wheel installed on the outer end of the guide bracket.

[0007] In one possible implementation, two guide rails are symmetrically installed on the front and rear sides of the main frame at the middle position. The guide rails extend vertically, and sliders are provided on the two guide rails in a sliding fit. Pins are symmetrically installed on the outer sides of the sliders, and the outer ends of the two pins are vertically connected to the same connecting rod.

[0008] The guide bracket is hinged to the main frame near the middle position. The inner end of the guide bracket has a strip-shaped guide hole that extends along the length of the guide bracket. The strip-shaped guide holes on the front or rear side of the guide bracket are respectively fitted onto the left and right symmetrical pins.

[0009] In one possible implementation, the main frame is equipped with a return roller and a rotary motor for driving the return roller to roll back the residual material to the suction cylinder. The rotating shaft of the rotary motor is fitted with a first rotating wheel, and the end of the return roller near the first rotating wheel is fitted with a second rotating wheel. The first rotating wheel and the second rotating wheel are connected by a transmission chain.

[0010] In one possible implementation, there are two of each of the blower and the suction cylinder. The two suction cylinders are symmetrically distributed on the left and right sides of the main frame and are respectively connected to the left and right ends of the container. The top of the container is symmetrically provided with air ducts connecting the container and the blower on the left and right sides. The air ducts are fitted with removable filter elements in a sealed manner.

[0011] In one possible implementation, a partition is provided near the center of the material container to divide the material container into two boxes. Two air ducts are respectively arranged on the top of the two boxes. The spiral conveyor shaft passes through the partition with a clearance fit to simultaneously transport the remaining material in the two boxes. The two fans are connected to the two boxes through the two air ducts, and then connected to the two suction cylinders respectively.

[0012] In one possible implementation, a rotating gear is fitted onto the end of the spiral conveyor shaft away from the discharge port, a servo motor is mounted on the outer wall of the container, and a drive gear is fitted onto the shaft of the servo motor corresponding to the rotating gear. The drive gear is connected to the rotating gear via a transmission component.

[0013] Beneficial effects: Compared with the prior art, the cargo box waste cleaning device provided in this application sets a spiral conveying shaft at the V-shaped bottom of the container and opens a discharge port on one side. The side discharge is carried out by the rotation of the spiral conveying shaft, which can realize online discharge during the cleaning process of the cargo box waste cleaning device, making discharge more convenient.

[0014] Through the cooperation of slider, guide rail, pin and connecting rod, the synchronous up and down swinging motion of the two guide mechanisms on the front or rear can be realized. The movement direction is highly accurate, the structure is simple and easy to maintain.

[0015] The return roller can roll back the residual material that was not collected in time by the suction cylinder, which can increase the residual material cleaning effect of the device to a certain extent.

[0016] The partition forms a seal between the two housings, allowing a single blower to form an independent suction system through the corresponding air duct, housing, and suction cylinder. Even if one suction system experiences air leakage or other problems, it will not affect the normal operation of the other suction system, thus improving the reliability of the device for cleaning residual materials to a certain extent.

[0017] These and other objects, features and advantages of this utility model will be fully realized through the following detailed description. Attached Figure Description

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0025] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0026] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0027] refer to Figures 1 to 6 This application provides a vehicle compartment waste cleaning device, including a main frame 10. Guide mechanisms 20 are symmetrically arranged on the left and right sides of the main frame 10 for guiding the device as it moves and cleans within the vehicle compartment. The main frame 10 has a milling roller 30 near the lower front side for milling the remaining material at the bottom of the carriage. Simultaneously, a suction cylinder 40 is located at the bottom of the main frame 10 to fully absorb the milled material. A material container 50 is located in the middle of the main frame 10, and a fan 60 is installed above the material container 50. The fan 60 and the suction cylinder 40 work together to draw the remaining material from the carriage into the material container 50. Furthermore, the material container 50 is V-shaped, and a spiral conveyor shaft 51 is located at the bottom of the material container 50. A discharge port 501 is located on the left or right side of the bottom of the material container 50 for unloading via the spiral conveyor shaft 51. This allows the device to simultaneously unload material during the cleaning process, making unloading more convenient and enabling unloading without stopping the machine, thus improving the efficiency of cleaning remaining material from the carriage to a certain extent. A plug 52 is installed on the discharge port 501 to seal the discharge port 501 when discharge is not required.

[0028] In one embodiment, there are four guiding mechanisms 20, which are symmetrically distributed at the four corners of the main frame 10. Each guiding mechanism 20 includes a guide bracket 21 that can swing up and down, and a horizontal guide wheel 22 and a vertical guide wheel 23 installed on the outer end of the guide bracket 21. This allows for flexible guidance of the device through the rotational cooperation of the horizontal guide wheel 22 and the vertical guide wheel 23. The up-and-down swing design of the guide bracket 21 allows the horizontal guide wheel 22 and the vertical guide wheel 23 to better adhere to the side wall of the carriage, ensuring the guiding effect.

[0029] In one embodiment, two guide rails 11 are symmetrically installed on the front and rear sides of the main frame 10 at the middle position. The guide rails 11 extend in the vertical direction, and sliders 12 are provided on the two guide rails 11 in a sliding fit. In addition, pins 13 are symmetrically installed on the outer side of the sliders 12, and the outer ends of the two pins 13 are vertically connected to the same connecting rod 14.

[0030] The guide bracket 21 is hinged to the main frame 10 near its center. A strip-shaped guide hole 201 is provided on the inner end of the guide bracket 21, extending along its length. The strip-shaped guide holes 201 on the front or rear guide brackets 21 are respectively fitted onto the symmetrically positioned pins 13. Moving either guide bracket 21 up or down at its outer end causes the other guide bracket 21, which remains on the same side of the front or rear position, to move up and down synchronously due to the hinged connection with the main frame 10. The sliding fit between the guide rail 11 and the slider 12 ensures the accuracy and stability of the guide bracket 21's deflection direction. When the slider 12 moves up and down, the pins 13 and connecting rod 14 move up and down synchronously, thereby driving the guide brackets 21 on both sides to deflect up and down synchronously through the strip-shaped guide holes 201. This results in high control precision. Furthermore, the overall structure of the guiding mechanism 20 is simple and easy to maintain.

[0031] In one embodiment, the main frame 10 is equipped with a return roller 15 and a rotary motor 16 for driving the return roller 15 to roll back the residual material to the suction cylinder 40. The rotary motor 16 has a first rotating wheel sleeved on its shaft, and the return roller 15 has a second rotating wheel sleeved on one end near the first rotating wheel. The first rotating wheel and the second rotating wheel are connected by a transmission chain 17. Thus, the rotary motor 16 can drive the return roller 15 to rotate in a directional and constant speed, rolling back the residual material that has not been collected by the suction cylinder 40 in time. This can improve the residual material cleaning efficiency of the device to a certain extent and achieve a better cleaning effect.

[0032] In one embodiment, there are two of each of the blower 60 and the suction cylinder 40. The two suction cylinders 40 are symmetrically distributed on the left and right sides of the main frame 10 and are respectively connected to the left and right ends of the material container 50 to improve the suction speed and suction range of the device. The top of the material container 50 has symmetrically arranged air ducts 52 on the left and right sides, connecting the material container 50 and the blower 60. A removable filter element 53 is installed in a sealed manner within the air ducts 52.

[0033] More preferably, a partition 54 is provided near the center of the material container 50 to divide the material container 50 into two boxes 511. Two air ducts 52 are respectively arranged at the top of the two boxes 511, and the spiral conveying shaft 51 passes through the partition 54 with a clearance fit to simultaneously transport the residual material in the two boxes 511. In addition, two blowers 60 are connected to the two boxes 511 through the two air ducts 52, and then connected to the two suction cylinders 40 respectively. In this way, each blower 60, together with its corresponding air duct 52, box 511 and suction cylinder 40, can form an independent suction system. Two identical suction systems exist in the device at the same time, and are relatively sealed and isolated by the partition 54 (there is only a partial conveying gap at the spiral conveying shaft). Even if one suction system has problems such as air leakage and affects the suction efficiency, the other suction system will not be affected. This can improve the reliability of residual material cleaning of the device to a certain extent.

[0034] In one embodiment, combined Figure 4 The spiral conveyor shaft 51 has a rotating gear 512 fitted at the end away from the discharge port. A servo motor is installed on the outer wall of the container 50, and the shaft of the servo motor is fitted with a drive gear corresponding to the rotating gear. The drive gear is connected to the rotating gear through a transmission component, which can be a transmission belt or a transmission chain.

[0035] It should be noted that the terms "first" and "second" used in this application are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
