Abstract

The utility model belongs to the improvement of the opencast mining device, particularly a soft ore body disc slitting machine which comprises a tractor. The front end of the machine frame of the slitting machine is hinged on a suspension device of the tractor; one end of a lifting arm hinged with a lifting oil cylinder of the suspension device is hinged on the suspension device frame, and the other end is hinged with a lifting pull rod; the lower end of the lifting pull rod is hinged on the machine frame. A main shaft arranged on the rear end of the machine frame through a bearing is provided with at least two disc saws. A power output shaft of the tractor drives a transmission shaft, and the transmission shaft drives the main shaft with disc saws through a cone gear to rotate. When the utility model slots the open-air coal seam vertically and horizontally, the coal seam is divided into square block shape or oblong block shape and is scooped up and loaded by a loader directly. The utility model can increase the blocking rate of the produced block coal and reduce the powder coal, and has low labor intensity, safe production, high work efficiency, high speed of machinery loading and reduction of production cost.

Description

Soft ore body disk groover

Technical field

The utility model belongs to the improvement of opencast mining equipment, particularly soft ore body disk groover.

Background technology

Soft ore body comprises colliery and saltcake ore deposit.At present, the exploitation in open coal mine and open-air saltcake ore deposit all is to adopt the exploitation method of drilling and blasting on ore body.It is many that this exploitation method is applied in the foam coal that the exploitation of open coal mine produces, and labour intensity is bigger, and the production safety problem is many, inefficiency, and mechanical loading speed is slow, the cost of production height.

The utility model content

The purpose of this utility model is to provide a kind of soft ore body disk groover, can improve the one-tenth piece rate of the lump coal of producing, and reduces the foam coal, and labour intensity is lower, production safety, and high efficiency, mechanical loading speed reduces production costs than very fast.

The purpose of this utility model is achieved in that a kind of soft ore body disk groover, comprise tractor, the front end of groover frame is hinged on the suspension arrangement of tractor, the hinged lift arm one end of the elevating ram of suspension arrangement is hinged on the suspension arrangement frame, the articulated raising rod of the other end, the lower end of raising rod is hinged on the frame, on the main shaft of the rear portion of frame, at least two disk saws are installed by the bearing installation, the power output shaft of tractor drives power transmission shaft, and power transmission shaft rotates by the main shaft that Bevel Gear Drive is equipped with disk saw.

The utility model is when walking, and the elevating ram of tractor suspension arrangement rises the frame of groover.When working on the soft in the open ore body of the utility model, as the coal seam, the elevating ram of tractor suspension arrangement descends, and the frame of groover is slowly descended.Reduce throttle this moment, engages power output shaft, makes power output shaft drive the disk saw rotation, and beginning is the cutting fluting on the coal seam, treats that disk saw cutting coal seam slots behind the certain depth, handles the tractor Ultra-Low Speed and advance, and speed is 42m/h-280m/h.Behind vertical and horizontal fluting on the coal seam, directly the coal seam behind the fluting can be scooped up entrucking through the utility model with loader.Owing to avoided on the coal seam, drilling and blasting, produce safelyr, the coal seam after loader directly will be slotted scoops up entrucking, the one-tenth piece rate height of coal, the coal foam of generation is few.Because coal mining activity is carried out the mechanical matching operation, has improved loading speed, has improved operating efficiency significantly, has alleviated working strength of workers, has saved the labour, has reduced cost of production.

The specific embodiment

A kind of soft ore body disk groover, as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, comprise caterpillar tractor, the front end of groover frame 6 is hinged on the suspension arrangement of tractor, the elevating ram 3 hinged lift arm 2 one ends of suspension arrangement are hinged on the suspension arrangement frame, the articulated raising rod 4 of the other end, the lower end of raising rod 4 is hinged on the frame 6, rear portion in frame 6 is installed with main shaft 7 by bearing, at least two disk saws 9 are installed on main shaft 7, and the quantity of disk saw 9 is 2-6.Spacing between the disk saw 9 is 0.4-1.4m.Welding alloy blade on the sawtooth of disk saw 9 respectively, alloy blade is a carbide chip 11.It is staggered that the sawtooth of disk saw 9 uniform on the edge of saw disc face is the left and right sides.Be distributed at disk saw 9 and welding the cutting tool 10 that two ends have the symmetry cutting basil on the saw disc face in the through hole.Because the sawtooth of disk saw 9 is cutting tool 10 staggered and that be provided with in the uniform through hole on the saw disc face about on the edge of saw disc face, the cutting basil of symmetry is stretched out the both sides in the saw disc card, the groove that disk saw 9 is opened on the coal seam has enough width, reduces the wearing and tearing of saw disc again and has reduced the phenomenon of saw disc frictional heating.Guard shield 8 is installed respectively on the disk saw above the frame 69.The effect of guard shield 8: playing the effect of security protection on the one hand, is the coal foam gathering that disk saw is slotted on the coal seam and produced on the other hand, delivers to the back of frame 6.The power output shaft 1 of tractor is connecting power transmission shaft 5 by universal coupling, and the logical universal coupling of the other end of power transmission shaft 5 is connecting bevel pinion shaft, and bevel pinion shaft rotates by the main shaft 7 that conical gear 12 transmissions of installing on the main shaft are equipped with disk saw.

Adopt the utility model to slot in length and breadth on the coal seam in the open, behind fluting, the coal seam is divided into box-shaped or pane shape, directly scoop up entrucking with loader.
