Rotary arm milling machine for coal mining roadway

Abstract

The invention discloses a rotary arm milling machine for a coal mining roadway. The rotary arm milling machine includes a walking chassis, a rotating table, a rotation mechanism, a suspension arm anda cutting part. The rotary arm milling machine has the advantages that 1, remote control can be achieved through a remote controller to achieve man-machine separation, the visibility of a cutting surface during work is good, no dead area exists, and the operation is facilitated; 2, through a sliding cylinder of a sliding rail and a sliding cylinder of the rotary table, the movement of the suspension arm and the cutting part on a sliding saddle in the front and rear directions and the left and right directions can be controlled, the distance is adjusted without moving a vehicle, and the operation efficiency is improved; 3, personnel can operate remotely, and the potential safety hazards are reduced; 4, the whole cutting part can penetrate into an operation surface, no cutting dead angle exists, and the rotary arm milling machine is suitable for slotting engineering work; and 5, an intermediate base material can be cut off by using cutting teeth on a cover plate chain, the cutting part does not need to swing from side to side, equipment is not prone to being damaged, the cutting efficiency is high, cutting teeth are arranged on the cover plate chain of the cutting part and a cuttingroller, the cutting part can penetrate directly into the cutting surface, the cutting depth can be formed in one time, and the cross section is smooth.

Description

[0001] Technical field: [0002] The invention relates to a milling machine, in particular to a rotary arm milling machine for a coal mining roadway. [0003] Background technique: [0004] The fully-mechanized mining face is generally designed as a panel. One panel is divided into many fully-mechanized mining faces. In the panel, there are transportation lanes, ventilation lanes, and connection lanes. During the mining process, it is necessary to build temporary wind walls and permanently seal them Walls, water pumps, etc., traditional temporary wind walls, permanent airtight wall slots and water pump pits are excavated manually with the most primitive method of picks, or hand-held with wind picks, which is labor-intensive , low efficiency, and large potential safety hazards; at present, some roadway slotting equipment has appeared on the market to replace manual operations, which can improve operating efficiency to a certain extent, but there are the following problems: 1.

Problems solved by technology

[0004] The fully-mechanized mining face is generally designed as a panel. One panel is divided into many fully-mechanized mining faces. In the panel, there are transportation lanes, ventilation lanes, and connection lanes. During the mining process, it is necessary to build temporary wind walls and permanently seal them Walls, water pumps, etc., traditional temporary wind walls, permanent airtight wall slots and water pump pits are excavated manually with the most primitive method of picks, or hand-held with wind picks, which is labor-intensive , low efficiency, and large potential safety hazards; at present, some roadway slotting equipment has appeared on the market to replace manual operations, which can improve operating efficiency to a certain extent, but there are the following problems: 1. During operation, it is impossible to realize human The machine is separated, and the operator needs to operate the equipment in the equipment cab, which has a blind spot and is inconvenient to operate; 2. In the process of slotting or mining, it is necessary to frequently move the equipment to adjust the working position of the cutting part, which is inefficient; 3. 1. There are potential safety hazards for people in the equipment cab, especially when excavating the top of the roadway, the flying coals can easily hurt the construction personnel; 4. The cutting part of the existing roadway slotting equipment is usually driven by a motor , gear box or chain drive to drive the cutting drum to rotate, use the picks on the cutting drum to mill the working surface, when the cutting depth reaches the head of the gear box, the box head conflicts with the working surface, and the longitudinal depth cutting is limited , the working surface of the head of the reducer cannot be cut, and there is a cutting dead angle, and this structure is not suitable for slotting engineering operations; 5. The cutting part usually drives the cutting drum to rotate through the motor, the reduction box and the middle chain drive, In order to avoid coal remaining in the corresponding part of the chain, the left and right swing arms must be used to cut the remaining matrix during work. The left and right swinging resistance is large, the work efficiency is low, the equipment is easily damaged, and the manual control of the tractor will easily cause the working surface to be uneven. The working depth cannot be formed at one time
