DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5A scraper for coal transportation in this embodiment includes a body 1, and both front and rear side plates of the head end of the body 1 are slidably connected with mounting plates 11, and the head end rotating shaft of the body 1 is installed between the two mounting plates 11, and the inner side of the head end of the body 1 is located on the left side of the rotating shaft and is fixedly connected with a fixing plate 12, and the opposite sides of the two mounting plates 11 are fixed with movable tooth plates 14 that penetrate through both sides of the fixing plate 12 by screws, and a concave plate 18 is fixed between the left sides of the two movable tooth plates 14, and the right side of the concave plate 18 is rotatably connected with a sleeve rod 19 that is threadedly connected to the fixing plate 12.

[0022] In the above structure, the sleeve rod is rotated to move left and right on the fixed plate, thereby pushing the concave plate to the left, and the movable tooth plate will pull the mounting plate to move at the same time, thereby driving the rotating shaft to tighten the chain. When disassembly and assembly are required, the upper cover plate at the front end of the machine body is removed, and the part connected by the internal screws is removed. Then, the sleeve rod is separated from the fixed plate by rotating, so that the internal movable tooth plate connection assembly can be disassembled, replaced or maintained together, and it is also convenient for the staff to perform installation operations.

[0023] In order to play a limiting role, the sleeve rod 19 is threadedly connected with a nut on the right side of the fixed plate 12, and a latch is clamped at the right end of the sleeve rod 19. When the sleeve rod adjusts the concave plate to a suitable position and adjusts the tension, the nut is rotated on the sleeve rod to move close to the fixed plate, so that the sleeve rod can be limited, and the latch can limit the nut and the sleeve rod to prevent the nut from falling off and the sleeve rod from falling off.

[0024] At the same time, in order to improve the firmness of the tension, a spring 20 is sleeved on the outer side of the sleeve rod 19 between the concave plate 18 and the fixed plate 12, and a fixing cylinder 16 is fixed on the right side of the concave plate 18 on the outer side of the sleeve rod 19. The spring is pressed by the fixed plate and the concave plate, so that the spring has a force to push to the left, which can effectively improve the firmness of the tension, and under the action of the fixing cylinder, the concave plate and the fixed plate are limited to avoid collision or too close proximity.

[0025] As above, the upper tooth plate 15 is inserted on the right side of the fixed plate 12, and the upper tooth plate 15 plug-in part is a U-shaped block. The teeth at the bottom of the upper tooth plate 15 are inclined to the lower left, and the teeth of the movable tooth plate 14 are inclined to the upper right, and the upper tooth plate 15 is meshed with the movable tooth plate 14. When the sleeve rod is adjusted, the sleeve rod pushes the concave plate to move, and pulls the movable tooth plate to move at the same time. Therefore, the inclined cooperation between the movable tooth plate and the upper tooth plate can make the movable tooth plate move to the left. When the tension needs to be loosened in a specific situation, the upper tooth plate needs to be lifted up so that the U-shaped block at the plug-in part of the upper tooth plate moves a certain distance on the fixed plate, and the movable tooth plate and the upper tooth plate are separated for adjustment. At the same time, after the adjustment and tension, the meshing between the movable tooth plate and the upper tooth plate can also effectively prevent relaxation and improve the firmness of the chain tension.

[0026] The movable tooth plate 14 is U-shaped, and the front and rear side plates of the head end of the body 1 are both fixed with rolling bearings 17 located inside the U-shaped movable tooth plate 14 by screws. The bearings fixed by screws can support the movable tooth plate, and under the action of the bearings, the smoothness of the movement of the movable tooth plate can be improved.

[0027] In addition, an arc plate 13 located between the fixing plate 12 and the rotating shaft of the machine body 1 is fixed between the two mounting plates 11 by screws. When the mounting plate moves, the arc plate can also move with it at the same time, and under the action of the arc plate, the coal mine can be limited.

[0028] At the same time, a support frame 2 is fixed at the feed port of the machine body 1, a funnel 3 is installed on the support frame 2, a discharge port 4 is formed at the bottom of the funnel 3, a quantity control component is arranged outside the discharge port 4, a crushing box 9 is fixed on the top of the funnel 3, and a crushing device 10 is installed inside the crushing box 9. The coal is crushed into a suitable size by the crushing device, and then enters the funnel for storage, and the coal is introduced into the machine body to complete the transportation by controlling the falling amount of the quantity control component, so as to avoid the introduction of large or more coal, which will block the transportation inside the machine body and affect the transportation of the coal, thereby reducing the transportation efficiency.

[0029] The control assembly includes a V-shaped block 5 hinged on both sides of the front and rear of the discharge port 4, a connecting rod 7 and a baffle 6 are fixed between the two V-shaped blocks 5, and a cylinder 8 movably connected to the connecting rod 7 is hinged on one side of the support frame 2. The connecting rod is driven by the cylinder to drive the V-shaped block to move, so that the baffle blocks the discharge port or separates from the discharge port, thereby achieving the function of controlling the discharge of coal.

[0030] The working principle of the above embodiment is:

[0031] Before conveying the coal, open the upper cover at the front end of the machine body, and push the concave plate to the left by rotating the sleeve rod. At the same time, the movable tooth plate moves with the concave plate. Then, under the action of the bearing, it can support the movable tooth plate and improve the smoothness of movement. At the same time, the mounting plate and the arc plate will also move with it. When adjusted to the appropriate position, the upper tooth plate also meshes with the movable tooth plate, and the spring forms a thrust on the concave plate, thereby effectively improving the firmness of the chain tension. At the same time, under the action of the arc plate, the coal can be blocked to avoid splashing to the left. After the pre-adjustment is completed, the coal is introduced into the crushing box, crushed to the appropriate size by the crushing device, and poured into the funnel. When a certain amount is reached in the funnel, the cylinder runs and pushes the connecting rod. The connecting rod drives the V-shaped block to move in a fan shape, and can also drive the baffle to move, thereby opening and closing the discharge port to complete the controlled discharge, and then the coal is transported through the machine body.

[0032] At the same time, after a long period of use, by opening the upper cover at the front end of the body, unscrew the screws at the position connected by screws inside, and then unscrew the nuts and pins, and then rotate the sleeve rod to make the sleeve rod continue to push the concave plate to the left until the sleeve rod is separated from the fixed plate. Therefore, the internal tensioning assembly can be disassembled, repaired or replaced. At the same time, when installing, repeat the above operations to complete its installation.

[0033] The entire workflow is completed, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
