Description

Technical Field

[0001] This invention relates to a conveniently adjustable clearing chute for the bridge section of a roadheader, belonging to the technical field of coal mining equipment. Background Technology

[0002] The bridge-turn unit of the roadheader is used to connect the roadheader and the conveyor belt. The bridge-turn unit moves forward as the entire roadheader advances. The bridge-turn unit is equipped with a cleaning chute and a discharge roller to transfer coal blocks from the roadheader to the conveyor belt. In the specific working process, the coal blocks are first pushed into the cleaning chute. The cleaning chute flattens the accumulated coal blocks as the roadheader moves forward. Then the discharge roller works to transport them to the belt conveyor, thus realizing the transportation of coal.

[0003] The existing clearing chute structure cannot flatten the coal blocks when the roadheader moves forward. Especially after the coal retaining plates are installed at both ends of the unloading drum, the coal blocks accumulate directly on the inner side of the coal retaining plates, which is not conducive to the operation of the unloading drum.

[0004] Chinese Patent No. CN 218402492 U discloses a conveniently adjustable cleaning chute for the bridge section of a roadheader, comprising: two symmetrically arranged coal retaining plates connected by a pressure plate, forming a cleaning chute between the two coal retaining plates and below the pressure plate; a connecting plate with a mounting plate fixedly connected to its side, the mounting plate being connected to the end of the pressure plate by screws; an upper housing fixedly connected to the top of the pressure plate; horizontal waist holes are formed on the side of the connecting plate and on both sides of the mounting plate, with limit pins connected at the horizontal waist holes; and horizontal elongated grooves are formed on the side of the coal retaining plates. The mounting plate is located outside the coal retaining plate, and the mounting plate passes through the horizontal long groove and is connected to the pressure plate.

[0005] In the above technical solution, by setting an upper shell on top of the pressure plate, when the roadheader moves forward, the bottom pressure plate can block the coal blocks entering from the front into a flat layer. The internal unloading roller can then effectively transport the coal blocks to the conveyor belt. The top shell plays an auxiliary blocking role. Moreover, when there is a lot of coal, some coal can accumulate above the top of the upper shell and pass over it, preventing the coal accumulation layer from being too high and improving the working efficiency of the unloading roller.

[0006] However, the above technical solution still has the following technical problems: the height and length of the pressure plate are fixed and cannot be adjusted according to the amount of coal, so its applicability is not strong. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a conveniently adjustable cleaning chute for the bridge section of a roadheader, so as to solve the technical problems existing in the prior art.

[0008] The technical solution adopted in this invention is as follows: a conveniently adjustable clearing chute for the bridge section of a roadheader, including baffles and pressure plates. The number of baffles is set to two and they are vertically installed at both ends of the unloading drum. The baffles are perpendicular to the axis of the unloading drum. The pressure plates are installed between the two baffles and located at the lower part of one side of the baffles. The pressure plates include multiple pressure plate units connected end to end in sequence.

[0009] Preferably, the pressure plate unit is rectangular, and one end of one of two adjacent pressure plate units is provided with a rectangular protrusion, and the other is provided with a rectangular groove that cooperates with the rectangular protrusion. The rectangular protrusion and the rectangular groove are respectively provided with first threaded holes, and the rectangular protrusion and the rectangular groove are fixed by connecting bolts.

[0010] Preferably, the mounting plate has mounting shafts fixed at both ends, and the baffle has a vertical first through hole and a plurality of L-shaped second through holes. The vertical end of the second through hole is arranged vertically downward, and the horizontal end of the second through hole communicates with the first through hole. The baffle has a second threaded hole on one side of the vertical end of the second through hole. The second threaded hole is threadedly connected to a limit bolt, and the limit bolt abuts the mounting shaft against the inside of the second through hole.

[0011] Preferably, the spacing between each of the second through holes is 10-15 cm.

[0012] Preferably, the length of each pressure plate unit is 20-30cm.

[0013] The beneficial effects of this invention are: 1. Compared with the prior art, the pressure plate in this invention includes multiple pressure plate units connected end to end in sequence, and the number of pressure plate units is set according to actual needs.

[0014] 2. Compared with the prior art, the baffle of the present invention is provided with a first through hole and multiple second through holes. The mounting shaft is installed inside the second through hole and is limited by the limiting bolt. When it is necessary to change the height of the pressure plate, the limiting bolt is loosened, the mounting shaft is slid from the second through hole to the first through hole, and then slid into another second through hole as needed. The mounting shaft is then limited by the limiting bolt. The vertical height of the pressure plate can be adjusted without disassembling the baffle, which is convenient. Attached Figure Description

[0017] Figure 3 This is a side view of the baffle. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] The reference numerals in the accompanying drawings include: baffle 1, pressure plate unit 2, protrusion 3, connecting bolt 4, mounting shaft 5, first through hole 6, second through hole 7, and limit bolt 8.

[0020] Example 1: The easily adjustable clearing chute of the roadheader bridge turnout, such as... Figure 1 As shown, it includes a baffle 1 and a pressure plate. The number of baffles 1 is set to two and they are vertically installed at both ends of the unloading drum. The baffles 1 are perpendicular to the axis of the unloading drum and are rectangular steel plates. The pressure plate is installed between the two baffles 1 and is located at the lower part of the front side of the baffles 1.

[0021] like Figure 2 As shown, the pressure plate includes multiple pressure plate units 2 connected end to end in sequence. Each pressure plate unit 2 is rectangular. One of the two adjacent pressure plate units 2 on the left has a rectangular protrusion 3 on its right end, and the other has a rectangular groove on its left side that mates with the rectangular protrusion 3. The rectangular protrusion 3 is inserted into the rectangular groove, and the rectangular protrusion 3 and the rectangular groove are respectively provided with first threaded holes. The rectangular protrusion 3 and the rectangular groove are fixedly connected by connecting bolts 4. The number of pressure plate units 2 is set according to actual needs.

[0022] like Figure 2 As shown, mounting shafts 5 are fixed at both ends of the mounting plate, as... Figure 3 As shown, the baffle 1 is provided with a vertical first through hole 6 and four L-shaped second through holes 7. The vertical end of the second through hole 7 is arranged vertically downward, and the horizontal end of the second through hole 7 is connected to the first through hole 6. A second threaded hole is provided on the right side of the vertical end of the second through hole 7 on the baffle 1. A limit bolt 8 is connected to the internal thread of the second threaded hole. The limit bolt 8 presses the mounting shaft 5 against the inside of the second through hole 7.

[0023] When the height of the pressure plate needs to be changed, loosen the limiting bolt 8, slide the mounting shaft 5 from the second through hole 7 to the first through hole 6, and then slide it into another second through hole 7 as needed. Then, use the limiting bolt 8 to limit the mounting shaft 5. In this embodiment, the vertical height of the pressure plate can be adjusted without disassembling the baffle 1, making adjustment convenient.

[0024] In this embodiment, the spacing between each second through hole 7 is 10cm.

[0025] In this embodiment, the length of each pressure plate unit 2 is 20cm.
