Problems solved by technology

However, the thickness of the existing coal seam usually has a certain range of variation in the direction of the coal seam. Therefore, for the existing all-in-one machine with a fixed height, it can only recover the coal

Embodiment 1

[0023] Example 1 see figure 1 , figure 2 , a height-adjustable shearer fuselage unit, an integrated coal mining and transporting machine for horizontal or near-horizontal propelling continuous lateral coal cutting and coal transportation, including a horizontally arranged bottom plate 1 and top plate 2, and bottom plate 1 and top plate 2 The wall panel is connected into an I-shaped frame; the two sides of the wall panel body 3 are fixedly connected with horizontal partitions 7, and the two horizontal partitions 7 separate the frame into a king shape, thereby forming a double-layer coal cutting area distributed up and down, and the top plate 2 The lower end surface, the upper end surface of the bottom plate 1 and the upper and lower ends of the horizontal partition 7 are provided with annular guide rails 10, and the two guide rails 10 in the coal cutting area of ​​the same layer are used for the circular movement guide of the same chain plate; The main body 3 and the telescop...

Embodiment 2

[0025] Example 2, see image 3 , the hydraulic lifting device is formed by at least two pressure cylinders 6, the free end of the piston rod 6a of the pressure cylinder 6 is hinged at the lower end of the cuboid part of the telescopic body 4, and the cylinder bottom ends of the two pressure cylinders 6 are hinged on the bottom plate 1 superior. Wherein, the two sealing rings 8 are used to prevent the sliding fitting section between the telescopic body 4 and the wallboard body 3 from being polluted by dust, so as to eliminate or slow down abnormal wear and prolong the service life. Wherein, the quantity of the pressure oil cylinder 6 is determined according to factors such as the length of the fuselage unit and the size of the pressure oil cylinder 6 .

[0026] The rest of the structure of this embodiment is the same as that of Embodiment 1, and will not be repeated here.

Embodiment 3

[0027] Example 3, see Figure 4 , Figure 5 , the only telescopic combination structure is formed by sliding fit of at least two circular column hole matching structures; wherein, the circular column hole matching structure includes at least two round holes 3b provided on the wallboard body 3, and the telescopic body 4 includes at least two cylindrical parts corresponding to the round holes 3b one by one; the hydraulic lifting device is formed by the same number of pressure cylinders 6 as the cylinder parts, and the piston rods 6a of the pressure cylinders 6 are hinged one by one. The lower end of the cylindrical part of the telescopic body 4 and the cylinder body of the pressure oil cylinder 6 are hinged on the base plate 1 . Wherein, the quantity of the pressure oil cylinder 6 is determined according to factors such as the length of the fuselage unit and the pressure oil cylinder 6; the cylindrical section of the expansion body 4 and the round hole 3b on the wallboard body ...

Abstract

The present invention discloses a coal cutter body unit with adjustable height, and the coal cutter body is used in a coal cutting and transportation integrated machine for horizontal or nearly horizontal advance continuous lateral coal cutting and coal transportation. The coal cutter body unit includes a base plate and a roof, which are horizontally disposed; the base plate and roof are connected into an H-shaped frame by a wallboard; the wallboard comprises the wallboard body and a telescoping body, which form an only-retractable composite structure in the direction of wall height; the wallboard body is fixedly connected to the base plate; the telescoping body is connected to the roof; and a hydraulic lifting device is arranged between the telescoping body and the wallboard body. Preferably, the only-retractable composite structure is formed by a rectangular plug cooperation structure, or at least two circular cylindrical cooperation structures in sliding fit. The present invention has the beneficial effects that the coal cutter body unit keeps the coal quality and recovery rate unchanged, when the coal seam thickness changes. The invention has the advantages of simple structure, maintenance convenience and low manufacture and usage cost.

Description

technical field [0001] The invention relates to a coal mining facility, in particular to a height-adjustable coal shearer fuselage unit of an integrated coal mining and transporting machine for horizontal or near-horizontal propelling continuous lateral coal cutting and transporting coal. Background technique [0002] The side-cutting continuous coal-cutting coal-mining integrated machine is an important facility to solve the mechanized unmanned coal mining of existing thin coal seams or relatively thin medium-thick horizontal or near-horizontal coal seams. It drives the drive chain to move horizontally through the drive sprocket. Coal mining is realized by setting coal cutting teeth on the chain plate connected to the drive chain, and the chain plate and the fuselage are used to form a coal transport trough, thereby forming an integrated machine structure that integrates coal mining and transportation, and the fuselage is used as the load-bearing part of the chain plate And...
