[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a mining truck bucket cleaning device, which includes a cleaning component 100 and a decontamination component 200. The cleaning component 100 is used to clean the inside of the bucket, and the decontamination component 200 is used to flush the reversing lights of the dump truck.

[0034] Specifically, the cleaning assembly 100 includes a drive member 101 mounted on the side of the truck bed, a water sprayer 102 mounted on the side and top of the truck bed, and a scraper 103 mounted inside the truck bed. The drive member 101 is connected to the cab and controls the movement of the scraper 103 within the truck bed, while the water sprayer 102 moves with the scraper 103, allowing it to spray water for further rinsing while cleaning.

[0035] Preferably, the dirt removal assembly 200 includes linkage members 201 on both sides of the bucket tail end and flushing members 202 arranged at the bottom of both sides of the bucket tail end. The scraper 103 can drive the flushing members 202 to flush the reversing lights covered by mud and dirt through the linkage members 201.

[0036] During use, if the inside of the bucket needs to be cleaned, the driver 101 can be activated to drive the scraper 103 to move inside the bucket, thereby scraping off the sticky dirt in the bucket. At this time, the dump truck can slightly lift the bucket to facilitate the pouring of dirt. While the scraper 103 is moving, the water sprayer 102 can also spray water into the bucket to further flush the dirt. The water sprayed by the water sprayer 102 can then enter the flushing unit 202 to further flush the dump truck's reverse lights, reducing driving risks.

[0037] Example 2

[0038] Reference Figures 2 to 11 , which is the second embodiment of the present invention, and is based on the previous embodiment.

[0039] Specifically, the drive element 101 includes a motor 101a and a coupling 101b, mounted on the front sidewalls of the truck bed. The motor 101a and coupling 101b rotate in unison. The drive element 101 also includes screw rods 101c, mounted on either side of the truck bed. The screw rods 101c rotate in unison with the sidewalls and coupling 101b, respectively. Motor 101a is a servo motor controlled by a switch inside the cab. Motor 101a and coupling 101b are connected by a sprocket and chain. The output end of motor 101a drives coupling 101b in rotation. Bevel gears are installed at each end of coupling 101b at the connection with screw rod 101c, transmitting power through the bevel gears. The screw rods 101c on either side of the truck bed are mounted in opposite directions, so that when both screw rods 101c rotate, they both cause the scraper 103 to move in the same direction.

[0040] Preferably, the water spraying element 102 comprises a water tank 102a mounted on the sidewall of the front end of the truck bed, a water pump 102b mounted above the water tank 102a, and a storage tray 102c and water distribution pipe 102d mounted on the top of the front end of the truck bed. The water tank 102a, water pump 102b, storage tray 102c, and water distribution pipe 102d are connected by pipes. The water pump 102b is also controlled by a switch inside the cab. Activating the water pump 102b pumps water from the water tank 102a through the water distribution pipe 102d and into the scraper 103. The storage tray 102c contains a reeled water pipe that can be pulled out and retracted at any time.

[0041] Preferably, the scraper 103 is vertically positioned within the truck bed, with its sides slidingly engaged with the side walls of the truck bed. Wedge-shaped slopes 103a are provided at each end of the scraper 103. The scraper 103 also includes at least one water spray channel 103b, which communicates with the water distribution pipe 102d. The bottom of the scraper 103 is sloped to facilitate the removal of sticky debris from the bottom of the truck bed. The water spray channel 103b extends from the top of the scraper 103 to the bottom and exits through the forward face of the scraper 103. The water inlet of each water spray channel 103b communicates with a respective channel of the water distribution pipe 102d.

[0042] Preferably, the linkage 201 includes a movable rod 201a disposed on either side of the rear end of the bucket. A pressure rod 201b is disposed at the bottom of the movable rod 201a. A first spring 201c is also connected below the movable rod 201a. The movable rod 201a slides in engagement with the sidewalls of the bucket. When the scraper 103 moves to the rear end of the bucket, the wedge-shaped slopes 103a at each end of the scraper 103 compress the top of the movable rod 201a, causing the movable rod 201a to descend vertically, driving the pressure rod 201b downward. The first spring 201c is a compression spring used to reset the movable rod 201a and the pressure rod 201b.

[0043] Preferably, flushing element 202 includes a coarse filter hole 202a located on the floor of the rear end of the truck bed, and a water collection box 202b located directly below the coarse filter hole 202a. Water collection box 202b has two side walls with chutes 202b-1. One side wall of water collection box 202b is half-open, and its bottom is also provided with an opening 202b-2. Coarse filter hole 202a prevents dirt or coal from the truck bed from falling into water collection box 202b. Water collection box 202b can be welded to the bottom of the rear end of the truck bed.

[0044] Preferably, the flushing member 202 further includes a first filter plate 202c and a second filter plate 202d disposed within the water collection box 202b. The first filter plate 202c is provided with first fine filter holes 202c-1, and the second filter plate 202d is provided with second fine filter holes 202d-1. The second filter plate 202d is disposed within the first filter plate 202c and slidably engages therewith. Both the first filter plate 202c and the second filter plate 202d are disposed at an angle. The first fine filter holes 202c-1 and the second fine filter holes 202d-1 are each provided in two rows on the first filter plate 202c and the second filter plate 202d, and their positions are staggered. That is, when the first filter plate 202c and the second filter plate 202d are combined, both the first fine filter holes 202c-1 and the second fine filter holes 202d-1 are obscured.

[0045] Furthermore, one end of the first filter plate 202c is positioned within the chute 202b-1 on one side and mounted on the baffle 202e, while one end of the second filter plate 202d is positioned within the chute 202b-1 on the other side. The second filter plate 202d is nested within the first filter plate 202c. When the end of the second filter plate 202d located within the chute 202b-1 begins to descend, the second filter plate 202d gradually retracts into the first filter plate 202c.

[0046] Preferably, the flushing member 202 further includes a baffle 202e disposed within the chute 202b-1 and positioned at the bottom of the ends of the first and second filter plates 202c and 202d, and a second spring 202f disposed at the bottom of the baffle 202e. The ends of the second spring 202f are fixedly connected to the baffle 202e and the bottom of the chute 202b-1, respectively. Two baffles 202e are provided, each connecting the two chute 202b-1. A through hole 202e-1 is also formed at the end of the baffle 202e. When the end of the second filter plate 202d located within the chute 202b-1 descends to the baffle 202e position, continued descent carries the baffle 202e downward with it. The second spring 202f is a compression spring that is used to reset the baffle 202e.

[0047] Furthermore, flushing member 202 includes a third spring 202g disposed at the bottom of one end of second filter plate 202d and located in the middle of second spring 202f. The ends of third spring 202g are fixedly connected to one end of second filter plate 202d and the bottom of chute 202b-1, respectively. Third spring 202g is also a compression spring and is used to reset the end of second filter plate 202d.

[0048] Furthermore, the flushing element 202 includes a water retaining pad 202i disposed on the inner bottom surface of the water collection box 202b and above the opening 202b-2, and a spray head 202j disposed at the bottom of the water collection box 202b and connected to the opening 202b-2. The water retaining pad 202i consists of two rubber pads with an interference fit, one covering the other. Under normal conditions, when the water collection box 202b stores water, the water retaining pad 202i does not leak. Only when pressure reaches a certain level does water break through the water retaining pad 202i and spray out of the spray head 202j, thereby removing dirt stuck to the backup lights. The spray head 202j can rotate freely.

[0049] During operation, motor 101a is activated, which drives coupling 101b, which in turn drives screw 101c. As screw 101c rotates, scraper 103 moves from the front end of the bucket to the rear end, removing sticky debris from the bottom. Simultaneously, water pump 102b is activated, pumping water from water tank 102a into spray channel 103b within scraper 103. Water is then ejected from the bottom outlet of spray channel 103b, flushing the bucket.

[0050] The flushed muddy water will flow into the water collecting box 202b from the coarse filter hole 202a at the rear end of the truck bed. Before the muddy water enters the bottom of the water collecting box 202b, it will first be filtered by the first filter plate 202c and the second filter plate 202d. Since the first filter plate 202c and the second filter plate 202d are set at an angle, part of the filtered muddy water will flow out from the side gap of the water collecting box 202b, and the cleaner muddy water will be temporarily stored at the bottom of the water collecting box 202b. When the scraper 103 gradually moves to the rear end of the truck bed, the wedge-shaped slopes 103a at both ends of the scraper 103 will gradually squeeze the moving rod 201a. When the moving rod 201a moves downward, the pressure rod 201b will also press the end of the second filter plate 202d downward. The end of the second filter plate 202d moves downward, gradually changing from an inclined state to a straight state, and in this process the second filter plate 202d will retract into the first filter plate 202c, and the first fine filter hole 202c-1 and the second fine filter hole 202d-1 are both blocked. At this time, the first filter plate 202c and the second filter plate 202d become a closed partition. When the end of the second filter plate 202d reaches the top of the baffle 202e, continue to press down the baffle 202e and it will move downward together. In this way, the first filter plate 202c and the second filter plate 202d will move downward together in a straight state. The internal space of the water collecting box 202b becomes smaller, and the stored water is squeezed to break through the water retaining pad 202i and sprayed out from the nozzle 202j. The muddy water will wash the reversing lights, wash away the mud on them, and reduce driving risks.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
