Embodiment Construction

[0014] like figure 1 A specific embodiment is shown, which includes a cutting device 1, a roadhead machine body 2 and an internal spraying device.

[0015] like figure 2 As shown, the cutting device 1 includes a cutting body 3, a pick 5, a hollow shaft 6, a self-aligning bearing 7, a thrust bearing 8, a cylindrical roller bearing 9, a connecting frame 10, a hydraulic motor 11 and a rear frame 12. The motor 11 is fixed on the rear frame 12, the hollow shaft 6 is arranged in the connecting frame 10 through the self-aligning bearing 7, the thrust bearing 8 and the cylindrical roller bearing 9, and the rear end of the connecting frame 10 is fixed on the rear frame 12. The rear end of the shaft 6 is connected with the hydraulic motor 11, so that the hydraulic motor 11 can drive the hollow shaft 6 to rotate. The cutting body 3 is fixed on the front end of the hollow shaft 6 , and a plurality of picks 5 are fixed on the cutting body 3 .

Abstract

The invention discloses an excavator which can reduce temperature with high efficiency and has internal spraying. The excavator comprises a cutting device, an excavator body and an internal spraying device; nozzles of the internal spraying device are arranged on the cutting device and comprise a nozzle I and nozzles II; the nozzle I is arranged at the central position of the head part of a cuttingbody of the cutting device; and a plurality of nozzles II are at distributed at the peripheral position of the head part of the cutting body of the cutting device. The nozzles of the internal spraying device can be opened only when in spraying; when in spraying, due to the pressure action of water, the dust can not enter the nozzles; and when not in spraying, the nozzles are in closed state, thedust also can not enter the nozzles, thus effectively avoiding blockage.

Description

technical field [0001] The invention relates to a roadheader, in particular to a roadheader with an internal spray that can efficiently cool down. Background technique [0002] During the cutting operation, the roadheader will produce sparks due to friction and heat. At present, there is a roadheader that can spray internally. This type of roadheader is equipped with an internal spray device. During the cutting operation, the internal spray can reduce the cutting The temperature of the device can effectively suppress the sparks generated by friction during cutting operations. However, the dust generated by the cutting can easily block the nozzles of the inner spraying device, so that the water cannot be sprayed smoothly from the nozzles, which affects the cooling of the cutting device. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a roadheader with an internal spray that can efficiently cool down, so that the ...
