Description

Technical Field

[0001] The utility model relates to the technical field of scaling jumbos, in particular to a slag cleaning mechanism for a scaling jumbo. Background Technique

[0002] In the underground mine excavation operation cycle, after blasting, it is necessary to remove the broken and unstable floating stones on the roof and both sides of the operation site to ensure the safety of on-site operators and equipment. Foreign mines have developed scaling jumbos on the basis of using handheld scaling tools, realizing the mechanization of scaling work.

[0003] The front end of the frame of a conventional scaling jumbo is equipped with a push shovel with a straight structure, which is used to clear the obstacles on the way of the jumbo's advance. However, due to this push shovel structure, the crushed stones and other obstacles on the ground will be concentrated and piled up directly in front of the push shovel. As the accumulation amount increases, the entire push shovel and the scaling jumbo will receive huge resistance, thus affecting the advancement and operation of the scaling jumbo.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a slag cleaning mechanism for a scaling jumbo is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a slag cleaning mechanism for a scaling jumbo to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A slag cleaning mechanism for a scaling jumbo, including a guide plate and a push shovel. A support member is horizontally connected to the top of the guide plate. The push shovel is horizontally installed at the bottom of the guide plate, and a hydraulic frame is connected to one side of the push shovel. Moreover, a rolling roller is horizontally installed at the center of the lower end of the hydraulic frame. A shovel tooth is horizontally welded to the front end of the push shovel. The push shovel includes a shovel plate, a guiding inclined plane, and a support pile. A guiding inclined plane is arranged at the edge of the top of one side of the shovel plate, and a support pile is connected to the side of the shovel plate away from the guiding inclined plane.

[0007] Further, the guide plate is arranged in an isosceles triangle structure, and the left and right inclined planes of the guide plate are arranged in an inward concave arc surface structure. Moreover, the side edges of the guide plate extend obliquely towards the left and right sides of the advancing direction respectively, and the outward protruding sharp angle of the guide plate faces the advancing direction of the scaling jumbo.

[0008] Further, the support member is arranged in an isosceles triangle structure and is horizontally welded to the top surface of the guide plate. The support member is used to strengthen the structural support for the horizontal pushing of the guide plate.

[0009] Further, the bottom of the shovel plate is arranged in a planar structure, and the guiding inclined plane is arranged on the side of the shovel plate facing the advancing direction of the scaling jumbo and has an isosceles triangle structure, and the support piles are symmetrically connected to one side of the shovel plate on the left and right.

[0010] Further, the pushing shovel and the guiding plate are welded together, and the side of the pushing shovel provided with the guiding inclined plane extends out of the bottom of the guiding plate on the side facing the advancing direction of the scaling jumbo.

[0011] Further, the hydraulic frame includes a hydraulic cylinder, a rotating bracket and a connecting frame. The power output end at the bottom of the hydraulic cylinder is connected to the rotating bracket, and one end of the hydraulic cylinder away from the rotating bracket is connected to the connecting frame.

[0012] Further, both the hydraulic cylinder and the rotating bracket are connected to the left and right ends of the connecting frame, and the side of the rotating bracket away from the hydraulic cylinder is fixedly connected to the support pile.

[0013] Further, the rolling roller is horizontally connected to the middle of the left and right rotating brackets, and the rolling roller is used to level the ground waste residue in the middle at the rear of the pushing shovel.

[0014] The utility model provides a slag cleaning mechanism for a scaling jumbo, which has the following beneficial effects:

[0015] 1. In the utility model, when the driving force is provided by the advancement of the scaling jumbo, at this time, the guiding plate and the supporting member at its bottom will simultaneously utilize the structural downward pressure provided by the hydraulic frame and translate along the ground. At this time, under the structural action of the pushing shovel, the waste residue and stones on the ground will be shoveled up from the ground. Under the action of the guiding inclined plane, along with the horizontal pushing force, the waste residue is pushed away from the ground and accumulates towards the guiding plate. With the structural action of the guiding plate, the accumulated waste residue and stones will be obliquely pushed towards the left and right sides respectively, so as to provide an effective slag cleaning effect for the advancement of the scaling jumbo as much as possible. By using the above structure, sufficient slag cleaning effect can be provided for the entire scaling jumbo in the advancing direction, and to the greatest extent, while cleaning the slag, it is possible to prevent a large amount of waste residue and stones from accumulating directly in front of the guiding plate, causing a large resistance to the advancement of the entire scaling jumbo and affecting its smooth advancement. In addition, by welding shovel teeth at equal intervals at the front end of the shovel plate, on the one hand, it can effectively assist in loosening the waste residue and crushed stones on the ground, cooperate with the operation of the hydraulic frame to shovel up the stones and waste residue, and avoid the stones getting stuck with each other as much as possible, which affects the advancement of the entire scaling jumbo. On the other hand, it also reduces the direct contact area between the stones and waste residue and the front end of the shovel plate during the advancement process, reduces structural accumulation, and further increases the resistance in front of the entire guiding plate, affecting the smooth advancement of the scaling jumbo. In addition, the shovel teeth can also provide effective structural assistance for the device as much as possible without changing the entire structure, providing good structural assistance for cleaning the waste residue.

[0016] The utility model uses a hydraulic frame connected with a supporting pile on one side of the bulldozer. Under the structural extension and contraction of the hydraulic cylinder, the structural rotation of the rotating bracket can provide sufficient grounding downward force for the bulldozer and the guide plate connected on the top to ensure that the overall structure can move along the ground, remove the waste slag and stones on the ground during the movement, prevent the device structure from "jumping" up and down due to the waste slag, and provide effective structural stability. At the same time, a rolling roller is horizontally installed in the middle of the lower end of the hydraulic frame, and the rolling roller is set on the rear side of the moving direction of the bulldozer. With the downward force provided by the hydraulic frame, the ground can be rolled and leveled, and half of the waste slag and gravel can be crushed to prevent larger stones from causing unnecessary influence on the movement of the prying trolley, further providing good assistance for the movement of the prying trolley. In addition, the use of the support member provides structural reinforcement for the guide plate, so that it has sufficient structural strength when pushing the waste slag and gravel on the ground, reducing the structural damage of the guide plate caused by the interaction force.

[0022] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0023] like Figures 1 to 4As shown in the figure, a slag cleaning mechanism for a scaling jumbo includes a guide plate 1 and a push shovel 3. A support member 2 is horizontally connected to the top of the guide plate 1. The push shovel 3 is horizontally installed at the bottom of the guide plate 1, and a hydraulic frame 4 is connected to one side of the push shovel 3. Moreover, a rolling roller 5 is horizontally installed at the center of the lower end of the hydraulic frame 4. A shovel tooth 6 is horizontally welded to the front end of the push shovel 3. The push shovel 3 includes a shovel plate 301, a guiding inclined surface 302, and a support pile 303. A guiding inclined surface 302 is provided at the top edge of one side of the shovel plate 301, and a support pile 303 is connected to the side of the shovel plate 301 away from the guiding inclined surface 302. The guide plate 1 is arranged in an isosceles triangle structure, and the left and right inclined surfaces of the guide plate 1 are arranged in a concave arc surface structure. Moreover, the side edges of the guide plate 1 extend obliquely towards the left and right sides of the traveling direction respectively, and the outward protruding sharp angle of the guide plate 1 faces the traveling direction of the scaling jumbo. The bottom of the shovel plate 301 is arranged in a flat structure, and the guiding inclined surface 302 is arranged on the side of the shovel plate 301 facing the traveling direction of the scaling jumbo and is in an isosceles triangle structure. Moreover, the support piles 303 are symmetrically connected to one side of the shovel plate 301. The push shovel 3 is welded to the guide plate 1, and the side of the push shovel 3 provided with the guiding inclined surface 302 extends out of the bottom of the guide plate 1 on the side facing the forward direction of the scaling jumbo. Under the structural action of the push shovel 3, the waste rocks on the ground will be shoveled up from the ground. Under the action of the guiding inclined surface 302, along with the horizontal pushing force, the waste will be pushed away from the ground and piled up towards the guide plate 1. And with the structural action of the guide plate 1, the piled-up waste rocks will be obliquely pushed towards the left and right sides respectively.

[0024] As Figures 1 to 4 shown in the figure, the support member 2 is arranged in an isosceles triangle structure and is horizontally welded to the top surface of the guide plate 1. The support member 2 is used to strengthen the structural support for the horizontal pushing of the guide plate 1. The hydraulic frame 4 includes a hydraulic cylinder 401, a rotating bracket 402, and a connecting frame 403. The power output end at the bottom of the hydraulic cylinder 401 is connected to the rotating bracket 402, and the connecting frame 403 is connected to the end of the hydraulic cylinder 401 away from the rotating bracket 402. Both the hydraulic cylinder 401 and the rotating bracket 402 are connected to the left and right ends of the connecting frame 403, and the side of the rotating bracket 402 away from the hydraulic cylinder 401 is fixedly connected to the support pile 303. The rolling roller 5 is horizontally connected to the middle of the left and right rotating brackets 402, and the rolling roller 5 is used to level the ground waste at the middle of the rear side of the push shovel 3. Under the telescopic action of the structure of the hydraulic cylinder 401, combined with the rotationality of the structure of the rotating bracket 402, sufficient ground contact pressure can be provided for the push shovel 3 and the guide plate 1 connected to the top. At the same time, by horizontally installing the rolling roller 5 at the middle of the lower end of the hydraulic frame 4 and setting the rolling roller 5 at the rear side of the traveling direction of the push shovel 3, combined with the downward pressure provided by the hydraulic frame 4, the ground can be rolled and leveled, and half of the waste rocks can be crushed.

[0025] In summary, as Figures 1 to 4As shown, when the slag cleaning mechanism for the scaling jumbo is in use, first, as the scaling jumbo travels, the hydraulic cylinders 401 at both ends of the connecting frame 403 will expand and contract in structure. At the same time, under the rotation of the rotating bracket 402, the bottom of the push shovel 3 will be pressed as close to the ground as possible and downward, and at the same time, the rolling roller 5 installed in the middle of the lower end of the hydraulic frame 4 will be pressed against the ground;

[0026] As the scaling jumbo moves forward, at this time, the shovel plate 301 will shovel horizontally along the ground. Utilizing the guiding inclined plane 302 and cooperating with the shovel teeth 6 at its front end, with the drive of the structure of the entire hydraulic frame 4, the waste slag and crushed stones on the ground will be shoveled and separated from the ground. At the same time, as the entire scaling jumbo moves forward, the shoveled waste slag and crushed stones will accumulate in front of the guiding plate 1. At the same time, the guiding plate 1 in the shape of an isosceles triangle, using the inclined inward concave arc surface structures on both sides, will push the accumulated waste slag and crushed stones to separate to the left and right sides, thereby cleaning the ground in the traveling direction of the entire scaling jumbo, and the rolling roller 5 will also roll the middle of the ground in the traveling direction to prevent unnecessary crushed stones from affecting the bottom of the scaling jumbo.

Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.
