Abstract
Provided is an autoamtic control mechanism for deep ploughing and balance of tillage machine, belonging to the field of agricultural machinery. Having the advantages of simple structure, convenient operation and usage as well as good effect in reducing labor intensity, the autoamtic control mechanism for deep ploughing and balance of tillage machine disclosed in the utility model aims to solve the problems of traditional tillage machines such as manual adjustment to the height of the balance wheel, the ship and the lever of a tail wheel in a mechanical manner, complicated structure and large labor intensity in operation. The utility model has the technical proposal that an oil inlet(3) of a gear box(1) of the tillage machine is communicated with an output port of an oil pump(2), wherein, an output port of the oil pump(2) is communicated with a hollow principal beam rack(9) which contains two closed ends. The lower end part of the principal beam rack(9) is connected with output ports of two floating type control valves(6) through a three-way joint. Output ports of the two control valves(6) are respectively communicated with a piston type adjustable balance wheel, a height oil cylinder(7) of the ship and a lever oil cylinder of an adjusting tail wheel(8). Oil outlets of the two control valves(6) are connected and communicated in parallel with oil return ports(4) of an oil pipe(5) and the gear box(1). An axle of the gear box(1) is connected with an axle of the oil pump(2).
Description
One. technical field
The utility model relates to agriculture harvesting and tillage machine tool, especially a kind of tilling depth of harvesting and tillage machine, balance automatic controls.
Two. background technology
Weak points such as the harvesting and tillage machine that suitable hilly ground uses is used widely in the rural area, but in use, is subjected to soil, or gradient influence, uses the height of mobile phone tool adjustment wheel, ship at any time, or the tail wheel lever, exists complex structure, and operation labour intensity is big.
Three. summary of the invention
The purpose of this utility model provides the tilling depth of harvesting and tillage machine a kind of simple in structure, easy for operation, the balance automatic controls.
The technical scheme that the purpose of this utility model adopted is, by gear-box, oil pump, oil pipe, control valve, adjustable stabilizer, the height oil cylinder of ship, regulate the tail wheel lever oil cylinder, the girder frame is formed, the gear-box oil-in of its harvesting and tillage machine is communicated with the input port of oil pump, the delivery outlet of oil pump is communicated with the girder frame that is hollow closed at both ends, girder frame bottom is communicated with the input port of two floating control valves with threeway, the output port of two control valves is communicated with adjustable stabilizer in the form of piston respectively, the height oil cylinder of ship and adjusting tail wheel lever oil cylinder, the oil-out of two control valves oil return opening of connecting oil pipe and gear-box in parallel is connected, and the axle of gear-box links with the axle of oil pump.
The utility model is to utilize the axle of gear-box and spool linking of oil pump, and the work of drive oil pump, oil pump is pressed into oil in the girder frame of the sealing that is hollow, and original air is compressed to the compressed air of going up end spaces formation certain pressure in the girder frame in the girder frame, if need adjustable stabilizer, ship, or during the tail wheel lever, by means of the oil that certain pressure is arranged in the girder frame, enter adjustable stabilizer by control valve, the height oil cylinder of ship, or regulate in the tail wheel lever oil cylinder, the motion of promotion piston, thereby reach automatic adjustment wheel, the height of ship, or the purpose of regulating the tail wheel lever are to satisfy tiller's operation needs, finish the purpose of adjusting, when piston surpassed setting value, the controlled valve of oil cylinder oil-out was opened, at this moment oil oil-out by control valve under the mechanical gravity effect, oil pipe, the oil return opening of gear-box, get back in the gear-box motion that goes round and begins again like this.
The utility model is simple and compact for structure, and fabrication and installation are convenient, manipulates flexibly, reduces labor intensity, and characteristics such as can regulate automatically according to the operation needs.
Four. description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the utility model sectional structure schematic diagram.
Among the figure: the height oil cylinder 8 of 1-gear-box, 2-oil pump, 3-oil-in, 4-oil return opening, 5-oil pipe, 6-control valve, 7-adjustable stabilizer, ship-adjusting tail wheel lever oil cylinder 9-girder frame
Five. embodiment
As shown in drawings, the input port of the oil-in 3 of gear-box 1, connection oil pump 2, the delivery outlet of oil pump 2 is communicated with girder frame 9 middle and lower parts of harvesting and tillage machine, girder frame 9 bottoms are communicated with two control valves 6 and adjustable stabilizer, the height oil cylinder 7 of ship and 8, two control valve 6 oil-outs of adjusting tail wheel lever oil cylinder are communicated with gear-boxes 1 by oil pipe 5 oil return opening 4.
