Description

Technical Field

[0001] This utility model relates to the field of thermal power generation, and more specifically, to a coal plow with anti-wear function. Background Technology

[0002] A plow unloader, also known as a plow-type unloader, is a device used to modify traditional conveying mechanisms. Plow unloaders are commonly used for unloading and separating coal and have advantages such as self-locking, no internal or external leakage, extremely high overload capacity, and stable operation.

[0003] The contact point between the conveyor belt edge and the plow blade experiences the greatest stress. Prolonged friction can cause the rubber on the belt edge to age and fall off. Long-term wear between the belt and the plow blade can create gaps at the contact point, leading to problems such as coal leakage or damage. To avoid this situation, a wear-resistant coal plow is proposed to solve the above problems. Utility Model Content

[0004] To overcome the wear between coal mine conveyor belts and equipment in the prior art, this utility model provides a wear-resistant coal plow, including a base, a straight frame fixedly installed on the top of the base, an installation frame hinged to the inner wall of the straight frame, a coal plow head fixedly installed at the end of the installation frame away from the straight frame, and a padding plate installed on the external thread of the coal plow head; A linear slide rail is fixedly installed on the outer wall of the base, and a coal hopper is slidably installed on the top of the linear slide rail. A receiving component is provided inside the coal hopper.

[0005] Preferably, the coal hopper includes a box body, which is slidably mounted on the top of a linear slide rail. An mounting base is fixedly mounted on the outer side wall of the box body, and a positioning screw is installed on the internal thread of the mounting base. A slot is provided on the top of the box body.

[0006] The empty slot provides space for adjusting the receiving components.

[0007] Preferably, the receiving component includes an outer rim bucket, a positioning plate is fixedly installed on the top of the outer rim bucket, the positioning plate has a positioning thread groove inside, the shape of the positioning thread groove is adapted to the positioning screw, and the outer rim bucket is connected to the positioning screw through the positioning plate and the positioning thread groove.

[0008] Preferably, a conveyor roller is fixedly installed on the top of the base, and a conveyor belt is provided on the outside of the conveyor roller.

[0009] Preferably, a belt limiting roller is fixedly installed on the top of the base.

[0010] Preferably, an electro-hydraulic push rod is provided at the top of the straight frame.

[0011] Preferably, the end of the electro-hydraulic push rod away from the straight frame is fixedly connected to the inner wall of the plow head.

[0012] Preferably, the padding plate is a polyurethane padding plate.

[0013] Used to reduce wear between the conveyor belt and the coal plow head.

[0014] Preferably, a discharge trough is provided at the center of the interior of the box.

[0015] Beneficial effects: The beneficial effects of adopting the technical solution of this utility model are as follows: (1) By adding linear slide rails on both sides of the base and sliding the coal hopper on the linear slide rails, an outer edge hopper is installed in the box to prevent material from falling out. The linear slide rails can adjust the distance between the box, the outer edge hopper and the conveyor roller, avoiding the problem of wear caused by hard contact between the conveyor belt outside the conveyor roller and the outer edge hopper. The height of the outer edge hopper can also be adjusted by changing the connection between the positioning screw and the positioning thread groove at different positions on the positioning plate, so that the outer edge hopper is always located on both sides below the contact surface between the conveyor belt and the coal plow head. This ensures that the material will not fall out and also avoids the problem of wear and aging of the conveyor belt.

[0016] (2) By adding a padding plate to the outside of the coal plow head, the problem of the conveyor belt directly contacting the coal plow head is avoided, which can protect the contact surface of the conveyor belt. In addition, the coal plow head will also cause wear and deformation problems when in contact with various coal and ore materials for a long time, which will affect the material diversion accuracy and cause leakage. Therefore, replacing the coal plow head with a padding plate not only makes it easier to replace the padding plate, but also solves the problem of high cost of replacing and repairing the coal plow head.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. The specific embodiments are as follows: like Figures 1 to 4 As shown, a wear-resistant coal plow includes a base 1, a straight frame 2 fixedly installed on the top of the base 1, a mounting frame 21 hinged to the inner wall of the straight frame 2, a coal plow head 7 fixedly installed at the end of the mounting frame 21 away from the straight frame 2, a pad 8 threaded on the external thread of the coal plow head 7, the pad 8 being a polyurethane pad 8, and a pad 8 with the same shape as the coal plow head 7 threaded on the external thread of the coal plow head 7. A conveyor roller 4 is fixedly installed on the top of the base 1, and a conveyor belt 41 is provided on the outside of the conveyor roller 4. The pad 8 replaces the contact surface of the coal plow head 7 and contacts the conveyor belt 41. As a polyurethane pad 8, it has lower hardness, resulting in less wear on the conveyor belt, and avoids the problem of wear and deformation caused by direct contact between the coal plow head 7 and the coal ore. Replacing the pad 8 is cheaper and easier to operate than maintaining and replacing the coal plow head 7. It should be noted that a linear slide rail 11 is fixedly installed on the outer wall of the base 1, and a coal hopper 5 is slidably installed on the top of the linear slide rail 11. A receiving component 6 is provided inside the coal hopper 5. The coal hopper 5 is used to collect the material after the coal head 7 has diverted it, while the receiving component 6 can fill the gap between the conveyor belt 41 and the coal hopper 5 to avoid the problem of material leakage and ensure that the material enters the coal hopper 5.

[0022] The coal hopper 5 includes a housing 50, which is slidably mounted on the top of a linear guide rail 11. A mounting base 51 is fixedly mounted on the outer wall of the housing 50, and a positioning screw 52 is threaded into the interior of the mounting base 51. A slot is provided on the top of the housing 50. The linear guide rail 11 controls the distance between the housing 50 and the conveyor belt 41, preventing direct contact that could cause wear on the side of the conveyor belt 41. The slot can be used to adjust the receiving component 6, which includes an outer edge hopper 60. A positioning plate 61 is fixedly mounted on the top of the outer edge hopper 60. A positioning threaded groove 62 is provided inside the positioning plate 61, the shape of which corresponds to the positioning screw 52. The outer edge bucket 60 is connected to the positioning screw 52 through the positioning plate 61 and the positioning threaded groove 62. The outer edge bucket 60 can be connected to the box body 50 through the positioning plate 61 and the positioning screw 52. The height of the outer edge bucket 60 and the conveyor belt 41 can be adjusted by the positioning plate 61. The positioning threaded groove 62 with different heights on the positioning plate 61 is connected to the positioning screw 52 to meet the compatibility requirements of the outer edge bucket 60 and the conveyor belt 41. The outer edge bucket 60 can always be set on both sides below the conveyor belt 41. The material enters the box body 50 and is discharged from the discharge chute 53. There are two coal dropping buckets 5 and two receiving components 6. In addition, a belt limiting roller 9 is fixedly installed on the top of the base 1. The belt limiting roller 9 can bend the two sides of the conveyor belt 41 upward, so that the conveyor belt 41 is not easy to drop materials and avoid hard wear with other parts. The number of belt limiting rollers 9 is determined according to the overall length of the conveyor line. An electro-hydraulic push rod 3 is installed on the top of the straight frame 2. The end of the electro-hydraulic push rod 3 away from the straight frame 2 is fixedly connected to the inner wall of the plow head 7. The electro-hydraulic push rod 3 is used to cooperate with the mounting frame 21 to raise and lower the plow head 7.

[0023] Working principle: First, adjust the height between the outer edge bucket 60 and the box 50 according to the height of the conveyor belt 41. Connect the outer edge bucket 60 and the box 50 by threading the positioning screw 52 with the positioning threaded groove 62 in the appropriate position. Adjust the sliding box 50 by adjusting the linear slide rail 11 to ensure that the outer edge bucket 60 is located below the contact surface between the conveyor belt 41 and the coal plow head 7 on both sides. After being diverted by the coal plow head 7, the material will enter the box 50 on both sides and be discharged from the discharge chute 53.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
