Description

Technical Field

[0001] The utility model relates to the technical field of scraper machines, in particular to a scraper machine head and a scraper machine having the same. Background Art

[0002] At present, in the process of mining advancement in the comprehensive mining face of coal mines, the scraper conveyor head often floats (climbs). If not handled in time, the scraper conveyor head will continue to climb, the mining height will be reduced, and even the hydraulic support and scraper conveyor will not be able to pass due to insufficient height, resulting in production suspension.

[0003] In order to solve the above problems, a single pillar is often used on site to press the shovel board on the coal side of the scraper conveyor head, so that the scraper conveyor head is pushed down, thereby increasing the mining height to ensure the normal passage of the equipment. The use of a single pillar to press the shovel board forces personnel to enter the coal side of the scraper conveyor, dig up the floating coal around the shovel board, and support the single pillar on the side of the shovel board and the top plate close to the coal wall, forming a certain angle so that the shovel board side is pressed down when the scraper head is pushed. This has the following disadvantages:

[0004] 1. Personnel enter the coal wall side of the scraper conveyor to work, which poses a safety hazard;

[0005] 2. It is necessary to clean the floating coal around the coal shoveling plate, set up single pillars (usually 3-4), push the scraper conveyor head to press down the side of the coal shoveling plate, and then recycle the single pillars, which is labor-intensive;

[0006] 3. When personnel enter the coal side to set up and recover the single pillar, the scraper conveyor needs to be stopped, resulting in a temporary suspension of production (20-30 minutes each time), affecting the recovery efficiency;

[0007] 4. When the press head is pressed, the damage rate is high due to the heavy load on the single support in an overloaded state;

[0008] 5. When pushing the scraper conveyor press head, the single support will break, posing a safety hazard of injury.

[0009] To address the above problems, no effective solution has been proposed yet. Utility Model Content

It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0041] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0042] Combination Figures 1 to 4 As shown, the scraper head in the prior art includes a head frame 11, a push plate 12 and a power assembly 40, the head frame 11 is fixedly connected to the push plate 12, the head frame 11 and the power assembly 40 are connected, the push plate 12 and the power assembly 40 are arranged on the same side of the head frame 11, the power assembly 40 is used to provide travel power, the head frame 11 is provided with a transition groove 13 and a deflection groove 14, the power assembly 40 includes a motor 41, a coupling 42 and a reducer 43, one end of the coupling 42 is connected to the output end of the motor 41; the other end of the coupling 42 is connected to the reducer 43, the reducer 43 is connected to the head frame 11, and the reducer 43 is connected to the head frame 11.

[0043] At present, in the process of mining advancement in the comprehensive mining face of coal mines, the scraper conveyor head often floats (climbs). If not handled in time, it will continue to climb, reducing the mining height and even causing the hydraulic support and scraper conveyor to be unable to pass due to insufficient height, thus leading to production suspension. Based on this phenomenon, the force conditions of the scraper head when it moves are analyzed. When working, the head frame 11 (about 13 tons) is on the coal bank side, and the power assembly 40 (about 15 tons) is on the old pond side. The head moves along the old pond side to the coal bank side. Figure 3 and Figure 4 As shown, below the head frame 11 and the power assembly 40 is an overall planar structure formed by the head pad and the push plate 12. Since the power assembly 40 is heavy and located on the Laotang side, the center of gravity of the head is biased toward the Laotang side (the side close to the power assembly 40). In addition, the head pad and the push plate at the bottom are in an overall planar state, which causes the center of gravity of the overall structure to be biased toward the Laotang side (the side close to the power assembly 40). In addition, the thrust of the hydraulic support on the head is consistent with the propulsion direction of the head, so that the head frame 11 is lifted away from the side of the power assembly 40, which eventually causes the head to continuously drift and climb during the propulsion process, affecting the mining process.

[0044] In order to solve the above problems, a single pillar is often used on site to press the shovel board on the coal side of the scraper conveyor head, so that the scraper conveyor head is pushed down, thereby increasing the mining height and ensuring the normal passage of the equipment. The use of a single pillar to press the shovel board forces personnel to enter the coal side of the scraper conveyor, dig up the floating coal around the shovel board, and support the single pillar on the side of the shovel board and the top plate close to the coal wall to form a certain angle so that the shovel board side is pressed down when the scraper head is pushed. However, the single pillar in this method is easy to damage, time-consuming and labor-intensive, and it is easy to cause injuries to workers, which poses a safety hazard and makes the mining efficiency low.

Instead of the prior art scheme of manually entering the coal side of the scraper conveyor and using a single pillar to press the shovel coal plate, it saves manpower and adjustment time, reduces safety hazards, improves the mining efficiency of the coal mine, and solves the problem of the head of the scraper conveyor being easy to float during the mining process in the prior art.
