Problems solved by technology

[0004] In addition, there is a milling machine. When working on rock formations with high hardness, a plurality of cutters are arranged on the outer surface of the cutting wheel of the milling device, and fixed bumps are arranged between the cutters. The bumps rotate with the cutting wheel to facilitate After cutting, the rock slag is removed, and after the milling wheel of the milling machine squeezes the rock formation to produce cracks, it is pumped out by a mud pump; such as the document of Patent No. CN101099004A, a cutting wheel structure is disclosed, and the outer edge of the cutting wheel is arranged on the surface There are multiple cutters, and the cutter is equipped with a bucket. The rotation of the cutting wheel drives the bucket to take out the cut rock and soil. Usually, it is difficult for this kind of bucket to ensure that it is close to the bottom of the trench.
[0005] If the bucket is set as a structure like an excavator, it needs to be controlled by the control device to adjust the position of the bucket. In the case of a large number of buckets, the structure is more complicated
[0006] When the groove depth is relatively shallow and the hardness of the rock layer is high, the energy consumption of the pumping and slag discharge method is relatively high, and the equipment structure is complicated. Since the cutting volume of the cutter is small each time, the state and position of the rock layer where cracks are generated are changed. Or it is difficult for the bucket to effectively take the rock slag out of the trench, which will easily cause the cutter to repeatedly squeeze the fallen rock slag, resulting in unnecessary energy loss

Abstract

The invention relates to a slotting device, and solves the problems of a poor deslagging effect and a short service life of an existing slotting device. The slotting device comprises a cutting arm, acutting wheel and a lifting jack, wherein the cutting wheel comprises a second hinge-joint point, a cutting wheel outer end surface and cutters; the cutters are fixedly connected to the cutting wheel;the cutting wheel rotates to drive the cutters to contact a rock stratum so as to break rock; the cutting wheel is in a circular shape; the second hinge-joint point is located in the circle center ofthe circular shape; the cutting wheel outer end surface is located on the circumference; the multiple cutters are arranged on the cutting wheel outer end surface; brushing and removing devices are arranged among the multiple cutters and are fixedly connected to the cutting wheel; the brushing and removing devices comprise elastomers connected with broom heads; and the broom heads are uniformly distributed in the width direction of the circumferential surface of the cutting wheel so as to cover the width of a groove. The broom heads brushes cracked rock stratums out of the groove along with the rotation of the cutting wheel, so that the working efficiency of the slotting device for slotting hard rocks is greatly improved.

Description

technical field [0001] The invention relates to a slotting device for breaking rock formations with high hardness. Background technique [0002] In the construction of using machinery to break the rock formation with high hardness, the rock formation is squeezed by the cutter, so that the rock formation at the squeezed place produces a dense core, and the dense core affects the surrounding rock formations to produce cracks, and then the rock formation is broken. [0003] This principle is widely used in shield machines. Since the working face of the rock layer is almost perpendicular to the ground when the shield machine is working, the rock layer will fall off from the working face by its own weight after the rock layer cracks. The working face after the rock layer falls off is beneficial to the cutter The working surface is squeezed to maintain high efficiency. [0004] In addition, there is a milling machine. When working on rock formations with high hardness, a pluralit...
