[0026] The present application provides the following technical solutions:

[0027] Embodiment one

[0028] Please refer to Figures 1-3 The present application provides a technical solution: a residual coal cleaning device, comprising a base 1, the bottom of the base 1 is fixedly connected with a universal wheel 2, the top right end of the base 1 is fixedly connected with a push handle 3, the left side of the bottom of the base 1 is provided with a first rectangular slot 4, the right side of the top of the base 1 is provided with a second rectangular slot 5, the left side of the top of the base 1 is provided with a lifting cleaning mechanism 6, the right side of the lifting cleaning mechanism 6 is provided with a scraping mechanism 7;

[0029] The lifting and cleaning mechanism 6 comprises a first fixed frame 61 fixedly connected to the top left side of the base 1, a bidirectional screw 62 rotatably connected to the front and back sides of the first fixed frame 61 near the top, a first fixed frame 61 fixedly connected to the front of the first fixed frame 61 near the top, a moving block 64 symmetrically screw-connected to the front and back surfaces of the bidirectional screw 62, a limiting rod 65 fixedly connected to the front and back sides of the first fixed frame 61 near the top and symmetrically left and right, a first hinged frame 66 fixedly connected to the bottom of the moving block 64, a hinged rod 67 hingedly connected in the first hinged frame 66, a second hinged frame 68 hingedly connected to the other end of the hinged rod 67, a second fixed frame fixedly connected to the bottom of the second hinged frame 68, a brush roller 69 rotatably connected to the front and back sides of the second fixed frame near the bottom, a second motor 611 fixedly connected to the front of the second fixed frame, a first pulley 612 fixedly connected to the output shaft surface of the second motor 611, a second pulley 613 fixedly connected to the surface of the brush roller 69 near the front end, and a belt 614 sleeved between the first pulley 612 and the second pulley 613.

[0030] A hole matched with the output shaft of the first motor 63 is formed in the front of the first fixed frame 61 near the top, and the output shaft surface of the first motor 63 penetrates and is rotatably connected in the hole. The output end of the first motor 63 is fixedly connected to the front end of the bidirectional screw 62.

[0031] Holes matched with the limiting rods 65 are formed in the front and left and right sides of the moving block 64, and the moving block 64 is slidably connected to the surface of the limiting rod 65 through the holes. The limiting rod 65 limits the moving block 64, so that the two moving blocks 64 move towards each other with the rotation of the bidirectional screw 62.

[0032] A hole matched with the output shaft of the second motor 611 is formed in the front of the second fixed frame, and the output shaft surface of the second motor 611 penetrates and is rotatably connected in the hole. A groove is formed in the front of the second fixed frame, and the surface of the second motor 611 is located in the groove.

[0033] Example two

[0034] Please refer to Figures 4-5 , and further obtain a scraping mechanism 7 on the basis of example one.

[0035] The scraping mechanism 7 comprises a connecting plate 71 fixedly connected to the right side of the second fixed frame, a slide rod 72 fixedly connected to the top right side of the base 1 and symmetrically front and back, a fixed block 73 fixedly connected to the bottom of the connecting plate 71 near the right side, a first fixed plate 74 fixedly connected to the bottom of the fixed block 73, a guide rod 75 symmetrically provided front and back on the top of the first fixed plate 74, a limiting plate 76 fixedly connected to the top end of the guide rod 75, a second fixed plate 77 fixedly connected to the bottom end of the guide rod 75, a spring 78 sleeved between the first fixed plate 74 and the second fixed plate 77 on the surface of the guide rod 75, and a scraping plate 79 fixedly connected to the bottom of the second fixed plate 77.

[0036] The bottom right side of the connecting plate 71 has a hole that matches the slide rod 72, and the connecting plate 71 is slidably connected to the surface of the slide rod 72 through the hole. The slide rod 72 supports the connecting plate 71, so that the connecting plate 71 can move up and down stably. The connecting plate 71 and the slide rod 72 can also support the second fixed frame.

[0037] The top front and rear sides of the first fixing plate 74 have holes that match the guide rod 75, and the guide rod 75 passes through the surface and slides up and down in the hole. The top end of the spring 78 is fixedly connected to the bottom of the first fixing plate 74, and the bottom end of the spring 78 is fixedly connected to the top of the second fixing plate 77.

[0038] In actual operation, when this device is in use, it is based on the base 1 as its support structure. The casters 2 at the bottom of the base 1 provide good mobility. The operator can easily push the device by holding the push handle 3 at the top right end, moving it to the location of the remaining coal to prepare for cleaning. The first motor 63 is started, and the output shaft of the first motor 63 rotates, driving the bidirectional screw 62, which is fixedly connected to it, to rotate within the first fixed frame 61. Since the surface of the bidirectional screw 62 is symmetrically threaded with moving blocks 64, and the holes on the left and right sides of the front of the moving blocks 64 match the limiting rods 65, under the limiting action of the limiting rods 65, the two moving blocks 64 can only move towards each other as the bidirectional screw 62 rotates. The first hinge frame 66 at the bottom of the moving blocks 64 is connected to the second hinge frame 68 through the hinge rod 67. The bottom of the second hinge frame 68... The second fixed frame is connected, thereby driving the second fixed frame and the brush roller 69 installed inside it to achieve lifting and lowering movement. During this process, the height of the brush roller 69 can be flexibly adjusted according to the thickness of the accumulated coal and the actual situation of the ground being cleaned, to ensure that the brush roller 69 maintains a suitable contact distance and pressure with the ground to achieve the best cleaning effect. When the brush roller 69 is adjusted to a suitable height, the second motor 611 is started. The output shaft of the second motor 611 drives the first pulley 612 to rotate. Through belt transmission, the second pulley 613 connected to the brush roller 69 rotates synchronously, thereby driving the brush roller 69 to rotate at high speed. The rotating brush roller 69 contacts the ground and brushes up the remaining coal, completing the cleaning action.

[0039] When the device moves to clean, the scraper 79 is connected to the first fixed plate 74 through the guide rod 75 and the spring 78. The elastic effect of the spring 78 enables the scraper 79 to adaptively adjust according to the ups and downs of the ground, so that the scraper 79 always closely adheres to the ground. After the residual coal is brushed up by the brush roller 69, the scraper 79 follows the brush roller 69 to scrape the residual coal left after the brush roller 69 is cleaned, further improving the thoroughness of cleaning and ensuring that the residual coal on the ground is cleaned as much as possible. At the same time, when the scraper 79 encounters an obstacle on the ground, the guide rod 75 slides upward in the hole of the first fixed plate 74, compressing the spring 78, which acts as a buffer to avoid damage to the scraper 79 and other parts of the device due to collision. The limiting plate 76 limits the distance of upward sliding of the guide rod 75, ensuring that the scraper 79 operates within the appropriate working range.

[0040] It should be noted that, in the present document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.
