DETAILED DESCRIPTION

[0034] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0035] The utility model provides a material box cleaning device for a dump truck, comprising:

[0036] Carriage 1;

[0037] Carriage 1 can transport earthwork materials;

[0038] A rear panel 2 is provided on one side of the carriage 1;

[0039] The upper end of the rear plate 2 is hinged to the upper end of the carriage 1, so that one side of the carriage 1 can be sealed, and the earth and materials in the carriage 1 can flow out;

[0040] The protective plate 3 is fixedly mounted on the upper end surface of the carriage 1 and away from the side of the rear plate 2;

[0041] The housing 4 is a pair and is disposed on the outer wall surfaces of both sides of the carriage 1;

[0042] One end surface of the housing 4 is fixedly connected to the side wall surface of the carriage 1 and can be relatively fixed;

[0043] The screw 5 is rotatably mounted in the housing 4;

[0044] A pair of sliding openings 6 are formed in the two side walls of the carriage 1 and are respectively located below the pair of shells 4;

[0045] The cleaning rack 7 is arranged in the carriage 1, and the outer wall surface thereof is in sliding contact with the inner wall surface of the carriage 1;

[0046] When the cleaning frame 7 slides, the earth and materials attached to the inner wall surface of the carriage 1 can be scraped off, so that the inner wall surface of the carriage 1 is kept clean and the earth and materials are prevented from being retained;

[0047] The connecting frame 8 is slidably installed in the sliding opening 6, and one end is fixedly connected to the outer wall surface of the cleaning frame 7, and the other end is threadedly connected to the screw rod 5;

[0048] The screw 5 rotates to drive the connecting frame 8 to slide in the sliding opening 6, so that the connecting frame 8 can drive the cleaning frame 7 to move simultaneously;

[0049] The driving mechanism is arranged on one side of the carriage 1 and is used for driving a pair of screw rods 5 to rotate.

[0050] Specifically, the driving mechanism includes:

[0051] A fixing plate 9 is fixedly mounted on the lower end surface of the protection plate 3;

[0052] The rotating shaft 10 is a pair, each of which is rotatably connected to one end surface of the fixed plate 9, and the other end is fixedly connected to one end of a pair of screw rods 5;

[0053] The first sprocket 11 is fixedly mounted on the outer surface of the rotating shaft 10;

[0054] The first chain 12 is meshed and connected with a pair of first sprocket wheels 11;

[0055] Under the action of the first chain 12, a pair of first sprocket wheels 11 and a pair of rotating shafts 10 can rotate simultaneously. The simultaneous rotation of the pair of rotating shafts 10 can respectively drive a pair of screw rods 5 to rotate simultaneously, so that the rotation speed of the pair of screw rods 5 is consistent.

[0056] Specifically, it also includes;

[0057] A rotating rod 13 is rotatably mounted on one end surface of the fixed plate 9, and one end of the rotating rod 13 is fixedly connected to one end of a rotating shaft 10;

[0058] The reducer 14 is fixedly mounted on a side wall of the carriage 1;

[0059] The second sprockets 15 are in a pair, one of which is fixedly mounted on the outer surface of the rotating rod 13, and the other second sprocket 15 is fixedly connected to the output end of the reducer 14;

[0060] The second chain 16 is also meshed and connected with a pair of second sprocket wheels 15;

[0061] The driving member 17 is fixedly mounted on a side wall of the carriage 1, and the output end is fixedly connected to the input end of the reducer 14;

[0062] The driving member 17 is a motor, and the rotation of its output end can drive the input end of the reducer 14 to rotate. The reducer 14 can reduce the speed of its input and drive a second sprocket 15 to rotate at the same time. At this time, under the action of the second chain 16, another second sprocket 15 and the rotating rod 13 can rotate at the same time. At this time, the rotation of the rotating rod 13 can drive a rotating shaft 10 to rotate.

[0063] Specifically, a connecting block 18 is provided in the sliding opening 6, one end surface of the connecting block 18 is fixedly connected to one end surface of the connecting frame 8, and the lower end surface of the connecting block 18 is provided with bristles 19 that contact the lower wall surface of the sliding opening 6;

[0064] When the connecting frame 8 slides in the sliding opening 6 , it can drive the connecting block 18 to move, and at the same time make the bristles 19 brush the lower wall surface of the sliding opening 6 to prevent earthwork materials on the lower wall of the sliding opening 6 from causing the sliding connecting frame 8 to get stuck.

[0065] Specifically, the surface of the cleaning rack 7 is clad with a wear-resistant layer;

[0066] The wear-resistant layer can effectively increase the service life of the cleaning frame 7.

[0067] Working principle: When the carriage 1 is pouring earth and materials, the rear plate 2 is opened to facilitate the pouring of earth and materials. However, some relatively wet earth and materials will adhere to the inner wall surface of the carriage 1. At this time, the staff starts the driving member 17. The rotation of the output end of the driving member 17 can drive the input end of the reducer 14 to rotate. The reducer 14 can reduce the speed of its input and drive a second sprocket 15 to rotate at the same time. At this time, under the action of the second chain 16, another second sprocket 15 and the rotating rod 13 can be rotated at the same time. At this time, the rotation of the rotating rod 13 can drive a rotating shaft 10, a first sprocket 11 and a screw 5 to rotate at the same time. At this time, under the action of the first chain 12, Another first sprocket 12 can drive another rotating shaft 10 and another screw 5 to rotate at the same time. At this time, the rotation of a pair of screws 5 can respectively drive a pair of connecting frames 8 to move, so that the pair of connecting frames 8 can slide in a pair of sliding openings 6 respectively. When the pair of connecting frames 8 move, they can drive the cleaning frame 7 to slide in the carriage 1. At this time, the cleaning frame 7 can scrape off the earth and materials attached to the inner wall surface of the carriage 1, so that the inner wall surface of the carriage 1 is kept clean, and the earth and materials in the carriage 1 are poured out. After the pouring is completed, the staff drives the output end of the driving member 17 to flip, so that the cleaning frame 7 moves back to its original position, which is convenient for scraping the earth and materials attached to the inner wall surface of the carriage 1 again, bringing convenience to people.
