Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a scraper plate assembly and a roadheader Background Art

[0002] The scraper plate assembly is an important part of the roadheader. Its main function is to load the coal broken by the cutting drum onto the supporting transfer equipment. However, the width of the roadway where the roadheader operates is not fixed. During the operation of the roadheader, it is unable to adjust the width of the scraper plate assembly in real time to adapt to roadways of different widths, resulting in a certain distance between the scraper plate assembly and the roadway wall surface. A large amount of coal materials will be left in this distance. To clean up the remaining coal materials, manual labor or other equipment is often required to collect them again after the roadheader moves its body, which will reduce the working efficiency of the roadheader to a certain extent.

[0030] As Figure 1 shown, the scraper plate assembly includes a main scraper plate 100, a secondary scraper plate 200, and a drive assembly 300. The main scraper plate 100 is integrally arc-shaped. The main scraper plate 100 is fixedly connected to the chassis 400 through a connection bracket 420. The secondary scraper plate 200 is slidably installed on the inner side wall of the main scraper plate 100. The drive assembly 300 is installed on the connection bracket 420. The drive assembly 300 drives the secondary scraper plate 200 to extend or retract from the main scraper plate 100 to adjust the overall width of the scraper plate assembly. In this application, the overall width of the scraper plate assembly refers to the sum of the width of the main scraper plate 100 and the width of the part where the secondary scraper plate 200 extends relative to the main scraper plate 100. The main scraper plate 100 is integrally arc-shaped. On the one hand, it can better adapt to the contour of the roadway, facilitate the flow of coal mine materials, reduce the scattering and rebound of coal mine materials, and avoid problems such as accumulation and blockage of materials during the loading process, thereby improving the working efficiency of the roadheader-anchoring machine. On the other hand, it can improve the structural strength of the main scraper plate 100 to adapt to the harsh working environment.

[0031] In some specific embodiments of the present utility model, two sets of scraper plate assemblies are installed on the same side of the chassis 400. The main scraper plate 100 in each set of scraper plate assemblies is fixedly connected to the chassis 400 through the corresponding connection bracket 420, and the secondary scraper plate 200 is slidably connected to the chassis 400.

[0032] In some specific embodiments of the present utility model, the main scraper plate 100 includes a first scraper plate wall 110 and a second scraper plate wall 120. Both the first scraper plate wall 110 and the second scraper plate wall 120 are arc-shaped to better adapt to the arc shape of the main scraper plate 100, reduce stress concentration, and improve the durability and reliability of the main scraper plate 100. The first scraper plate wall 110 is arranged above the second scraper plate wall 120, and the first scraper plate wall 110 and the second scraper plate wall 120 are fixedly connected by bolts to ensure that the main scraper plate 100 can withstand loads from different directions during the working process.

[0033] In some specific embodiments of the present invention, the angle between the first shoveling plate wall 110 and the second shoveling plate wall 120 is in the range of 175° to 180°, and preferably, the angle is 178°.

[0034] In some specific embodiments of the present invention, a first guide groove 410 is provided on a side of the chassis 400 close to the main shovel plate 100, specifically, on a side close to the second shovel plate wall 120. An L-shaped extension plate 500 is provided on the inner side wall of the main shovel plate 100, specifically, on the inner side wall of the first shovel plate wall 110, and the extension plate 500 and the inner side wall of the first shovel plate wall 110 form a second guide groove 510. In the process of the driving assembly 300 driving the auxiliary shovel plate 200 to move relative to the main shovel plate 100, the lower part of the auxiliary shovel plate 200 is always embedded in the first guide groove 410, and the upper part of the auxiliary shovel plate 200 is always embedded in the second guide groove 510. The first guide groove 410 and the second guide groove 510 provide a fixed path for the movement of the auxiliary shovel plate 200, ensuring the stability and accuracy of the auxiliary shovel plate 200 during the movement, so that the auxiliary shovel plate 200 can move smoothly and linearly, while reducing friction and wear.

[0035] In some specific embodiments of the utility model, a reinforcing rib 111 is provided on the inner side wall of the first shovel plate wall 110 to connect the entire extension plate 500, so as to improve the strength of the first shovel plate wall 110 and prevent deformation under the action of coal and mineral materials. In the present application, the first shovel plate wall 110 is provided with reinforcing ribs 111 on both sides along the width direction thereof. In the present application, the first shovel plate wall 110, the extension plate 500 and the reinforcing ribs 111 are integrally formed, which can improve the strength and durability, and also improve the production efficiency and the quality of the finished product.

[0036] In some specific embodiments of the present invention, a plurality of reinforcing ribs 210 are provided on the inner side wall of the auxiliary shovel plate 200 to improve the overall rigidity and strength of the auxiliary shovel plate 200 and avoid deformation under the action of coal and mineral materials.

[0037] In some specific embodiments of the utility model, the driving assembly 300 includes a cylinder 310 and a push plate 320, and the body of the cylinder 310 is mounted on a connecting bracket 420. A groove 220 is provided on the side of the auxiliary shovel plate 200 close to the connecting bracket 420 to avoid the body of the cylinder 310. In the present application, since the thickness of the auxiliary shovel plate 200 is relatively small, in order to facilitate the connection between the auxiliary shovel plate 200 and the push rod of the cylinder 310, the push plate 320 is installed at the bottom of the groove 220, and the end of the push rod of the cylinder 310 away from the body is fixedly connected to the push plate 320. In the present application, the width of the push plate 320 can be greater than the thickness of the auxiliary shovel plate 200, so that the connection between the push plate 320 and the auxiliary shovel plate 200 and the connection between the push rod and the auxiliary shovel plate 200 are staggered to avoid interference.

[0038] In some specific embodiments of the present utility model, on one side of the chassis 400 facing the main shovel plate 100, specifically on the side facing the second shovel plate wall 120, a pressing plate 430 is horizontally arranged. The pressing plate 430 is placed between the upper side wall and the lower side wall of the groove 220 and is close to the lower side wall of the groove 220. During the process of the driving assembly 300 driving the auxiliary shovel plate 200 to move relative to the main shovel plate 100, the pressing plate 430 presses the lower side wall of the groove 220 to prevent the auxiliary shovel plate 200 from tilting.

[0039] In some specific embodiments of the present utility model, a baffle 230 is arranged on the side of the auxiliary shovel plate 200 away from the connecting bracket 420. The baffle 230 has a planar portion and arc-shaped portions located on both sides of the planar portion, and the arc-shaped portions on both sides are symmetrically arranged. After the auxiliary shovel plate 200 retracts, the baffle 230 is attached to the main shovel plate 100 and the chassis 400 respectively through the arc-shaped portions on both sides, which can protect the main shovel plate 100 and the chassis 400 to a certain extent and avoid abrasion.

[0040] For the shovel plate assembly in the above technical solution, the driving assembly 300 drives the auxiliary shovel plate 200 to move relative to the main shovel plate 100 to adjust the width of the auxiliary shovel plate 200 extending out of the main shovel plate 100, so as to achieve the effect of adjusting the overall width of the shovel plate assembly. It can be applied to working environments in roadways with various different widths, and has a wide application range.
