Description
Technical field
The utility model relates to a kind of hoeing equipment, particularly a kind of drive hoeing machine that is applied to small drift.
Background technology
Drive hoeing machine is a kind of efficient hoeing equipment of working continuously, be mainly used in colliery, metallic ore and mine working, railway tunnel, diversion culvert, loading operation is taken off in digging of the various lump material such as defence construction, also can be used for outdoor native stone, the loading operation of sand material etc., traditional drive hoeing machine is to using hydraulic pressure as power, adopt the loading travelling platform of crawler type or rubber-tyred, conveying mechanism with suitable gradient integral installation on travelling platform, if the gradient is too high, rolling can occur material causes carrying not get on, if the gradient is too low, can cause conveying mechanism long, when work, the hydraulic pressure swing arm of drive hoeing machine is taken off material on the conveyer belt rolling, convey materials is once sent to the trolley that is arranged in rear, such structure weak point is: the conveying mechanism length of (1) integral body is long, fuselage is too high, because tunnel is too narrow, normally high 2 meters, wide 2 meters, drive hoeing machine is in tunnel during operation, fuselage is clumsy, advance and retreat limited, easily break pipeline and the circuit of fuselage and both sides, tunnel, (2) before conveyer belt, scroll end position is too high, when mechanical swing arm is taken off conveyer belt by material, when swing arm upwards lifts, easily bumps against top, tunnel, causes swing arm to be damaged.Such structure substantially cannot be worked in the tunnel of 2 meters * 2 meters.
Summary of the invention
The utility model provides a kind of compact conformation, small drift drive hoeing machine that conveying mechanism is short and small.
For achieving the above object, technical scheme of the present invention is:
A kind of small drift drive hoeing machine, comprise travelling platform, conveying mechanism, material scraper and hydraulic pressure swing arm, the centre of travelling platform is provided with conveying mechanism, the front end of conveying mechanism is provided with material scraper, the both sides above of conveying mechanism are arranged with respectively a swing arm pedestal, the upper end of pedestal is connected with hydraulic pressure swing arm, it is characterized in that:
Described conveying mechanism with material scraper for being flexibly connected, middle both sides above conveying mechanism are arranged with respectively a bearing, the both sides above of material scraper are respectively equipped with a front hydraulic cylinder and are connected with the bearing of its homonymy, and material scraper can be rotated by the tractive of front hydraulic cylinder up or down;
Hydraulic cylinder after both sides, rear portion above described conveying mechanism are respectively equipped with one, rear hydraulic cylinder is connected with the swing arm pedestal with its homonymy respectively.
The small drift drive hoeing machine of above structure, has following characteristics:
(1) conveying mechanism and material scraper are designed to be flexibly connected, because driving material scraper, front hydraulic cylinder rotates up or down, thereby the material in material scraper is sent in conveying mechanism, so when dress is taken off material, hydraulic pressure swing arm, without upwards lifting again, has overcome hydraulic pressure swing arm and has upwards lifted the problem that easily bumps against top, tunnel;
(2) after, hydraulic cylinder can swing arm pedestal be the transport gradient that fulcrum changes conveying mechanism, therefore needn't worry can make because the gradient is too high material that the problem that rolling causes conveying not got on occurs, so the drive hoeing machine that conveying mechanism can be relatively traditional designs more short and smallly.
Based on above 2 points, small drift drive hoeing machine of the present utility model has compact conformation, the short short feature of fuselage, be particularly useful for carrying out operation in small drift (2 meters * 2 meters), flexible operation is motor-driven, has improved and in tunnel, has dug the operating efficiency of taking off loading operation.
