Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyors, in particular to a foldable scraper for a scraper conveyor. Background Art

[0002] Scraper conveyor, also known as scraper conveyor, is one of the transportation equipment for coal mines and other materials. The scraper is driven by a chain to move in the middle trough to realize the transportation of materials. Sprockets that drive the chain to move are installed at the head and tail of the machine. The scraper is often placed in the middle trough and fixed to the chain in the middle trough by bolts.

[0003] During operation, since the height of the scraper is fixed, if the volume of a single material is too large, it is very likely that the material will cross the baffle and slide down when passing through the slope. Since the application environment of the scraper is relatively complex, sometimes it is necessary to transport larger materials. At this time, it is necessary to replace a higher scraper to meet the material transportation requirements. However, there are a large number of scrapers on the scraper and they are all fixed to the chain by bolts. Disassembly is time-consuming and labor-intensive, affecting the transportation efficiency of the scraper.

[0004] Therefore, it is necessary to propose a foldable scraper for a scraper machine, which can avoid disassembling the bolts while being able to adjust the height of the scraper machine to ensure the transportation efficiency of the scraper machine. Utility Model Content

[0005] The utility model aims to solve the problem that the scraper of the existing scraper machine is time-consuming and laborious to disassemble when adjusting the height, thereby affecting the transportation efficiency of the scraper machine. A foldable scraper for the scraper machine is provided.

[0006] The technical solution of the utility model is:

[0007] A foldable scraper for a scraper machine, comprising a base and a first baffle, wherein the first baffle is located on the top of the base and is rotatably connected to the base, the base is provided with a groove for accommodating the first baffle, the first baffle can be rotated relative to the base to be perpendicular to the base, and the first baffle can also be rotated into the groove to overlap with the base;

[0008] Limiting holes are provided on both sides of the first baffle plate, and limiting blocks are slidably connected in the limiting holes. When the first baffle plate is perpendicular to the base, the limiting blocks can slide from the limiting holes to both sides of the first baffle plate and contact with the top of the base, thereby preventing the limiting blocks from rotating relative to the base.

[0009] Furthermore, a second baffle is provided inside the first baffle, and the second baffle is slidably connected to the first baffle. When the first baffle is perpendicular to the base, the second baffle can slide from the inside of the first baffle to the top of the first baffle.

[0010] Furthermore, an outlet is provided on the first baffle, and the second baffle slides from the inside of the first baffle through the outlet to the top of the first baffle.

[0011] Furthermore, limiting protrusions are fixedly connected to both sides of the second baffle, and protrusion holes for accommodating the limiting protrusions are provided on the inner wall of the first baffle.

[0012] Further, the limiting hole includes a first convex head hole and a second convex head hole, and when the second baffle is located on the top of the first baffle, the limiting convex head is located in the first convex head hole;

[0013] When the second baffle is located inside the first baffle, the limiting protrusion is located in the second protrusion hole.

[0014] Furthermore, the bottom surface and the side surface of the groove are composed of an arc-shaped surface, and the side surface of the first baffle is an arc-shaped surface.

[0015] Furthermore, one side surface of the first baffle is an arc-shaped surface and the side surface is opposite to the groove, and the remaining side surfaces of the first baffle are vertical planes.

[0016] The utility model discloses a foldable scraper for a scraper machine. When the scraper does not need to be too high, the second baffle is retracted in the first baffle, and the first baffle is folded in the groove. Therefore, only the base installed on the chain is exposed to the outside. When the height of the scraper needs to be increased due to the volume of the material, the first baffle is rotated out of the groove so that the first baffle is perpendicular to the base. Then the limit block is placed on the top of the base to fix the position of the first baffle and the base. At this time, the height of the entire scraper is the height of the base and the first scraper, which fully meets the transportation needs of the materials and prevents the materials from moving relative to each other during transportation. Since the overall height of the scraper is changed completely by rotating the first baffle to make the first baffle vertically on the base, the whole process does not require the removal of bolts. Compared with the traditional technology, the technical solution avoids the removal of bolts while achieving the adjustment of the scraper height, thereby ensuring the transportation efficiency of the scraper machine.

[0025] In order to make the technical means, technical features, utility model objectives and technical effects achieved by the utility model easy to understand, the utility model is further explained below with reference to specific illustrations.

[0026] Embodiment 1:

[0027] like Figure 1 and Figure 4 As shown, this embodiment provides a foldable scraper for a scraper, comprising a base 1 and a first baffle 2, wherein the first baffle 2 is located on the top of the base 1 and is connected to the base 1 through a pin shaft, and a groove 3 for accommodating the first baffle 2 is provided on the base 1, and the first baffle 2 can be rotated relative to the base 1 to be perpendicular to the base 1, and the first baffle 2 can also be rotated into the groove 3 to overlap with the base 1;

[0028] Limiting holes 4 are provided on both sides of the first baffle plate 2, and limiting blocks 5 are slidably connected to the limiting holes 4 through guide rails. When the first baffle plate 2 is perpendicular to the base 1, the limiting blocks 5 can slide from the limiting holes 4 to both sides of the first baffle plate 2 and contact with the top of the base 1, thereby preventing the limiting blocks 5 from rotating relative to the base 1.

[0029] Preferably, Figure 2 and Figure 5 As shown, a second baffle 6 is further provided inside the first baffle 2, and the second baffle 6 is slidably connected to the first baffle 2. When the first baffle 2 is perpendicular to the base 1, the second baffle 6 can slide from the inside of the first baffle 2 to the top of the first baffle 2. When the second baffle 6 slides out from the first baffle 2, the overall height of the scraper can be further increased, thereby meeting the transportation needs of larger materials.

[0030] Preferably, Figure 3As shown, the first baffle plate 2 is provided with an outlet 7 , and the second baffle plate 6 slides from the inside of the first baffle plate 2 through the outlet 7 to the top of the first baffle plate 2 , and the opening is located at one end of the first baffle plate 2 .

[0031] like Figure 6 and Figure 7 As shown, preferably, limiting protrusions 8 are fixedly connected to both sides of the second baffle plate 6, and a protrusion hole for accommodating the limiting protrusion 8 is provided on the inner wall of the first baffle plate 2. The limiting protrusion 8 is made of rubber material. The limiting protrusion 8 made of rubber material will produce plastic deformation when squeezed and is also wear-resistant, thereby satisfying the friction loss borne by the limiting protrusion 8 when the second baffle plate 6 repeatedly slides in the first baffle plate 2.

[0032] Preferably, the limiting hole 4 includes a first convex hole 9 and a second convex hole 10. When the second baffle plate 6 is located at the top of the first baffle plate 2, the limiting convex head 8 is located in the first convex head hole 9. At this time, the limiting convex head 8 and the first convex head hole 9 can limit the sliding of the second baffle plate 6, so that the second baffle plate 6 can always be located at the top of the first baffle plate 2. When the second baffle plate 6 is located inside the first baffle plate 2, the limiting convex head 8 is located in the second convex head hole 10, so that the second baffle plate 6 can always be located inside the first baffle plate 2.

[0033] Preferably, the bottom and side surfaces of the groove 3 are composed of an arc-shaped surface, and the side surface of the first baffle 2 is an arc-shaped surface. The function of the arc-shaped surface is to more conveniently clean the material debris entering the groove 3 without inconvenience in cleaning the material debris due to the existence of corners.

[0034] Preferably, one side surface of the first baffle plate 2 is an arc-shaped surface and the side surface is opposite to the groove 3, and the other side surfaces of the first baffle plate 2 are vertical planes.

[0035] During operation, when the scraper does not need to be too high, the second baffle 6 is retracted in the first baffle 2, and the first baffle 2 is folded in the groove 3. Therefore, only the base 1 installed on the chain is exposed to the outside. When the height of the scraper needs to be increased due to the volume of the material, the first baffle 2 is rotated out of the groove 3 so that the first baffle 2 is perpendicular to the base 1, and then the limit block 5 is placed on the top of the base 1 to fix the position of the first baffle 2 and the base 1. At this time, the height of the entire scraper is the height of the base 1 and the first scraper, which fully meets the transportation needs of the materials and prevents the materials from moving relative to each other during transportation. Since the overall height of the scraper is completely changed by rotating the first baffle 2 to make the first baffle 2 vertical on the base 1, the whole process does not require the removal of bolts. Compared with the traditional technology, the technical solution avoids the removal of bolts while achieving the adjustment of the scraper height, thereby ensuring the transportation efficiency of the scraper.

[0036] The above description is only a preferred embodiment of the utility model, and is not intended to limit the scope of implementation of the utility model. That is, all equivalent changes and modifications made according to the content of the patent application scope of the utility model should belong to the technical scope of the utility model.
