Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal mine machinery and equipment technology, and in particular to a multi-functional coal cleaning vehicle for coal mines. Background Technology
[0002] In the coal mining and transportation process, coal cleaning cars are important equipment used for loading and transporting coal. However, when coal is transported through the interior of the coal cleaning car, it easily sticks to the inner walls and bottom of the car. After unloading, a large amount of coal remains inside the car, which not only wastes coal resources but also requires manual cleaning, increasing labor intensity and cleaning costs. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a multi-functional coal cleaning vehicle for coal mines, which solves the problem of difficulty in cleaning residual coal in existing coal cleaning vehicles.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] A multi-functional coal cleaning vehicle for coal mines includes a drive rod, which is slidably mounted on the top of the coal cleaning vehicle. Several cleaning forks are provided along the length of the bottom of the drive rod. The bottom ends of the cleaning forks are slidably mounted relative to the inner bottom surface of the coal cleaning vehicle, and the sides of the two cleaning forks at the ends are slidably mounted relative to the inner walls of the front and rear sides of the coal cleaning vehicle.
[0006] The two ends of the drive rod are slidably connected to the coal cleaning car via sliding components.
[0007] The sliding assembly includes two fixed plates, which are respectively installed on the top of the front and rear sides of the coal cleaning car. Sliding grooves are formed on the opposite surfaces of the two fixed plates. Sliding blocks are provided at both ends of the drive rod, and the drive rod is slidably connected to the sliding grooves of the fixed plates through the sliding blocks at both ends.
[0008] A rotating gate is installed on the coal outlet of the coal cleaning car.
[0009] The coal outlet of the coal cleaning car is also equipped with a blocking assembly for limiting the rotation of the gate.
[0010] The barrier assembly includes a fixed ring, a rotating shaft, and a limiting plate. The fixed ring is installed above the coal outlet on the coal cleaning car. The rotating shaft is mounted on the fixed ring, and a rotating plate is rotatably mounted on the rotating shaft. The rotating plate is connected to the limiting plate, and the limiting plate is pressed against the barrier gate after being rotated by the rotating plate.
[0011] The slide is fitted with a limiting post to restrict the sliding of the slider.
[0012] The top two ends of the gate are vertically fitted with guard plates.
[0013] A second handle is installed at the top of the drive lever, and a first handle is installed on the outside of the coal cleaning car via an inclined plate.
[0014] The bottom of the coal cleaning car is equipped with casters via support pillars.
[0015] Compared with the prior art, the beneficial effects of this utility model are: by sliding the slider on the groove opened on the fixed plate, the drive rod can be driven to slide synchronously. While the drive rod slides, the cleaning fork slides. Since the cleaning fork contacts the bottom of the coal cleaning car, the coal adhering to the bottom of the coal cleaning car can be effectively cleaned, avoiding coal residue, reducing coal resource waste, reducing cleaning costs, and improving the efficiency of the coal cleaning car.
[0016] The sides of the two cleaning forks at the ends slide relative to the inner walls of the front and rear sides of the coal cleaning car. When the drive rod drives the cleaning forks to slide, the coal adhering to the inner walls of the front and rear sides of the coal cleaning car can be cleaned at the same time, realizing all-round cleaning of the interior space of the coal cleaning car.
[0017] The limiting plate can be pressed onto the gate after being rotated by the rotating plate and rotating shaft, effectively limiting the gate and preventing it from loosening during transportation, thus ensuring the safety and stability of the transportation process; the limiting post can limit the slider, ensuring that the cleaning fork remains in a fixed position when not in use, further improving the stability of the device.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0025] A multi-functional coal cleaning vehicle for coal mines includes a drive rod 6, which is slidably mounted on the top of the coal cleaning vehicle 1. Several cleaning forks 7 are provided along the length of the bottom of the drive rod 6. The bottom ends of the cleaning forks 7 are slidably mounted relative to the inner bottom surface of the coal cleaning vehicle 1, which can effectively clean the coal remaining at the bottom of the coal cleaning vehicle 1. The sides of the two cleaning forks 7 at the ends are slidably mounted relative to the inner walls of the front and rear sides of the coal cleaning vehicle 1, which can clean the inner walls of the front and rear sides of the coal cleaning vehicle 1.
[0026] The two ends of the drive rod 6 are slidably connected to the coal cleaning car 1 through sliding components.
[0027] The sliding assembly includes a fixed plate 2, which has two members. The two fixed plates 2 are respectively installed on the top of the front and rear sides of the coal cleaning car 1. Sliding grooves 3 are opened on the opposite surfaces of the two fixed plates 2. Sliding blocks 4 are provided at both ends of the drive rod 6. The drive rod 6 is slidably connected to the sliding grooves 3 of the fixed plate 2 through the sliding blocks 4 at both ends.
[0028] A stop gate 12 is rotatably installed on the coal outlet of the coal cleaning car 1. A blocking assembly for limiting the rotation of the stop gate 12 is also installed on the coal outlet of the coal cleaning car 1.
[0029] The barrier assembly includes a fixed ring 8, a rotating shaft 9, and a limiting plate 11. The fixed ring 8 is installed above the coal outlet on the coal cleaning car 1. The rotating shaft 9 is mounted on the fixed ring 8, and a rotating plate 10 is rotatably mounted on the rotating shaft 9. The rotating plate 10 is connected to the limiting plate 11, and the limiting plate 11 is pressed against the barrier gate 12 after being rotated by the rotating plate 10. By rotating the limiting plate 11, the barrier gate 12 at the coal outlet can be limited and unlocked.
[0030] The slide groove 3 is fitted with a limiting post 19 to restrict the sliding of the slider 4, thereby limiting the slider 4 during the sliding operation.
[0031] Protective plates 15 are vertically installed at both ends of the top of the gate 12.
[0032] A second handle 18 is installed on the top of the drive lever 6, and a first handle 17 is installed on the outside of the coal cleaning car 1 via the inclined plate 16.
[0033] The bottom of the coal cleaning car 1 is equipped with casters 14 via support pillars 13.
[0034] By installing support pillars 13 and casters 14, the device can be easily moved by the user. The multi-functional coal cleaning car 1 for coal mines slides on the grooves 3 opened on the fixed plate 2 via slider 4, which in turn drives the drive rod 6 to slide. Simultaneously, the drive rod 6 drives the cleaning fork 7 to slide. The cleaning fork 7 contacts the bottom of the coal cleaning car 1, thereby cleaning the coal adhering to the bottom of the coal cleaning car 1. This facilitates the cleaning of coal ore left inside the coal cleaning car 1, preventing coal ore from easily sticking to the inner wall of the coal cleaning car 1, improving the transportation efficiency of the device for coal ore, and enhancing its practicality.
[0035] When using:
[0036] Users can move the coal cleaning car 1 to a designated position for coal loading by holding the first handle 17 on the inclined plate 16 and using the casters 14 at the bottom of the coal cleaning car 1. After loading is completed, the gate 12 is closed, and the limiting plate 11 is rotated to press against the gate 12, thereby limiting and fixing the gate 12 to ensure that coal does not leak during transportation.
[0037] When the coal cleaning car 1 arrives at the unloading location, rotate the limit plate 11 to disengage it from the gate 12, and then open the gate 12 so that the coal can be discharged through the coal outlet.
[0038] After unloading, the user can hold the second handle 18 at the top of the drive rod 6 and push the drive rod 6 to make the slider 4 slide on the groove 3 of the fixed plate 2. The drive rod 6 drives the cleaning fork 7 to slide inside the coal cleaning car 1. At this time, the cleaning fork 7 at the end simultaneously cleans the front and rear inner walls of the coal cleaning car 1 and thoroughly cleans the coal remaining at the bottom and inner walls of the coal cleaning car 1. The cleaned residual coal can be discharged through the coal outlet.
[0039] After cleaning, insert the limiting post 19 into the slide groove 3 to limit the slider 4, so that the cleaning fork 7 remains in a fixed position for easy use next time.
[0040] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
