Example Embodiment

[0058] Example 1

[0059] A spray channel structure provided in this embodiment is applied to a shearer drum. The shearer drum includes a cylinder body 10 and a blade 1 arranged on the cylinder body 10. The spray channel structure includes a blade water channel 101, a first water channel 2, The first radial hole 102, the first one-way valve 3 and the first spray assembly 4, the blade water channel 101 is arranged on the side of the blade 1 adjacent to the cylinder 10; the first water channel 2 is arranged near the outer peripheral end surface of the blade 1; the first diameter The blade waterway 101 and the first waterway 2 are connected to the hole 102; the first one-way valve 3 is arranged in the first radial hole 102, and is used to prevent the water in the first waterway 2 from flowing into the first radial hole 102; the first The spray assembly 4 is arranged on the outer peripheral end surface of the blade 1 and communicated with the first water channel 2 for spraying the...

Example Embodiment

[0066] Example 2

[0067] A spray waterway structure provided in this embodiment is applied to a shearer drum. The shearer drum includes a cylinder body 10 and an end plate 5 arranged on the cylinder body 10. The spray waterway structure includes an end plate waterway 501, a second waterway 6. The second radial hole 502, the second one-way valve 7 and the second spray assembly 8, the end plate water channel 501 is set on the side of the end plate 5 adjacent to the cylinder 10; the second water channel 6 is close to the outer peripheral end surface of the end plate 5 Setting; the second radial hole 502 communicates with the end plate waterway 501 and the second waterway 6; the second one-way valve 7 is arranged in the second radial hole 502 to prevent the water in the second waterway 6 from flowing into the second radial direction In the tunnel 502 ; the second spray assembly 8 is arranged on the outer peripheral end surface of the end plate 5 and communicated with the second w...

Example Embodiment

[0073] Example 3

[0074] A kind of shearer drum provided in this embodiment, see Figure 4 , including cylinder 10, blade 1 and end disk 5, blade 1 is connected to the outer peripheral surface of cylinder 10; end disk 5 is connected to the outer peripheral surface of cylinder 10, and is closer to the end of cylinder 10 than blade 1; this implementation The shearer drum provided in the example also includes the spray channel structure described in Example 1.

[0075]The coal shearer drum provided in this embodiment can ensure that the first radial hole 102 on the blade 1 is not blocked by the blockage in the first water channel 2, and at the same time spray the first spray assembly 4 on the first water channel 2 The water in a waterway 2 is sprayed onto the pick assembly 9 on the shearer drum, thereby ensuring that the first spray assembly 4 cools and removes dust on the pick assembly 9 when the water volume is relatively sufficient.

[0076] Further, the spray waterway stru...

Abstract

The invention discloses a spraying water channel structure and a coal mining machine roller. The spraying water channel structure comprises a blade water channel, a first water channel, a first radial hole channel, a first one-way valve and a first spraying assembly, wherein the blade water channel is arranged on one side, close to a roller body, of a blade; the first water channel is arranged close to the peripheral end face of the blade; the first radial hole channel communicates with the blade water channel and the first water channel; the first one-way valve is arranged in the first radial hole channel and is used for preventing water in the first water channel from flowing into the first radial hole channel; and the first spraying assembly is arranged on the peripheral end face of the blade, communicates with the first water channel and is used for spraying the water in the first water channel to a cutting tooth assembly on the coal mining machine roller. According to the spraying water channel structure provided by the invention, the problems in the prior art that the water sprayed by the spraying assembly only comes from the radial hole channel so that the cutting tooth assembly cannot be sprayed with the water after the radial hole channel is blocked, and the cooling and dust-removing efficiency of the cutting tooth assembly is relatively low, caused by the fact that the water storage amount in the radial hole channel is relatively small, can be avoided.

Description

technical field [0001] The invention belongs to the technical field of coal shearers, and in particular relates to a spray channel structure and a coal shearer drum. Background technique [0002] The waterway on the shearer drum at this stage, see figure 1 , the main form is that the inner spray water enters from the drum connection plate, and then passes through the connection plate water tank, the blade and / or the end plate water channel, the radial channel on the blade and / or the radial channel on the end plate, and then the inner spray water The pick assembly is cooled and dedusted by spraying onto the pick assembly through a spray assembly communicating with the radial holes on the respective blades and / or the radial holes on the end disk. [0003] Since the hole depths of the radial channels on the blade and the radial channels on the end disk can both reach 40-50 mm, and the aperture is about 10 mm, once the radial channels are blocked, it is difficult for the radial...
