Abstract
Control device is controlled in the trick two that the utility model discloses a kind of like this excavator rotation jaw, the problem that flexibility is poor, control difficulty is comparatively large, operating efficiency is lower that the control device rotating jaw for solving existing excavator exists, the utility model is taked to be arranged with cylinder (3) the foot-operated of described foot valve (2), cylinder (3) is connected with air valve (4) by pipeline, air valve (4) is connected with gas receiver (5) by pipeline, and cylinder (3) is connect by wire and button electricity.Thus there is the advantage that flexibility is good, control difficulty is less, operating efficiency is high.
Description
Technical field
The utility model relates to a kind of excavator, and control device is controlled in the trick two particularly relating to a kind of excavator rotation jaw be made up of pilot valve, foot valve, rotary valve block and jaw valve block.
Background technology
At present, market discloses a kind of excavator oil route controller, its design feature is: comprise pilot valve, foot valve, rotary valve block and jaw valve block, pilot valve is connected with foot valve by pipeline, foot valve is connected with rotary valve block and jaw valve block respectively by pipeline again, therefore, this structure can only be stepped on foot valve by pin and control rotation and the clamping that excavator rotates jaw, and its flexibility is poor, control difficulty is comparatively large, operating efficiency is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of flexibility trick two that is good, that control the excavator rotation jaw that difficulty is less, operating efficiency is high and controls control device.
For achieving the above object, control device is controlled in the trick two that the utility model excavator rotates jaw, comprise pilot valve, foot valve, rotary valve block and jaw valve block, pilot valve is connected with foot valve by pipeline, foot valve is connected with rotary valve block and jaw valve block respectively by pipeline again, and be arranged with cylinder the foot-operated of described foot valve, cylinder is connected with air valve by pipeline, air valve is connected with gas receiver by pipeline, and cylinder is connect by wire and button electricity.
The pipeline that described air valve is connected with gas receiver is provided with pressure meter.
Each described foot valve foot-operated under be symmetrically arranged with two cylinders, each cylinder is connected with an air valve by pipeline.
Described button be arranged on control handle or drive on table top.
After adopting this structure, owing to being provided with cylinder on described foot valve, cylinder is connected with air valve by pipeline, and air valve is connected with gas receiver by pipeline, and cylinder is connect by wire and button electricity.Thus realize trick two control, reach the object that flexibility is good, control difficulty is less, operating efficiency is high.
accompanying drawing explanationbelow in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing 1 is the schematic diagram that the utility model excavator rotates that control device is controlled in the trick two of jaw.
In figure: 1. rotary valve block 2. foot valve 3. cylinder 4. air valve 5. gas receiver 6. pilot valve 7. jaw valve block.
detailed description of the inventioncontrol device is controlled in the trick two that the utility model excavator shown in accompanying drawing 1 rotates jaw, comprise pilot valve 6, foot valve 2, rotary valve block 1 and jaw valve block 7, pilot valve logical 6 is crossed pipeline and is connected with foot valve 2, foot valve 2 is connected with rotary valve block 1 and jaw valve block 7 respectively by pipeline again, cylinder 3 is arranged with the foot-operated of described foot valve 2, cylinder 3 is connected with air valve 4 by pipeline, and air valve 4 is connected with gas receiver 5 by pipeline, and cylinder 3 is connect by wire and button electricity; The pipeline that described air valve 4 is connected with gas receiver 5 is provided with pressure meter; Each described foot valve 2 foot-operated under be symmetrically arranged with two cylinders 3, each cylinder 3 is connected with an air valve 4 by pipeline; Described button be arranged on control handle or drive on table top.
