Abstract
The utility model discloses an agricultural three-wheel cart tractor-ploughing suspension device, mainly comprising a traction draw rod fixed to a rear axle of a cart frame and a lifting arm controlling the lifting of the traction draw rod. The utility model is characterized in that the lifting arm is connected with a telescopic rod of an oil cylinder of a hydraulic oil cylinder, and the lifting arm lifts along with the telescopic rod of an oil cylinder; the rear end of the traction draw rod is connected with a triangular frame for a ploughshare; a control rod for controlling the penetrating angle of the ploughshare is arranged between the triangular frame for a ploughshare and the cart frame; the control rod can control the depth when the ploughshare works. The utility model has the advantages of simple structure, convenient operation and labor saving; the plowing can be realized by the method that only an operating handle on a distribution valve for an oil circuit is controlled; the utility model develops the functions of the agricultural three-wheel cart and has multiple functions. The utility model can be used for plowing in a busy farming season and can be used for transporting in a free farming season.
Description
The utility model relates to a kind of farm machinery, relates in particular to the agricultural tricycle tractor-ploughing suspension arrangement that a kind of agricultural tricycle is used for tractor-ploughing.
In the rural area, agricultural tricycle is mainly used in engages in transport, because the rural area summer harvest, the needs of the summer sowing and kind of the wheat of gatheing in the autumn crops, occur again in the market agricultural motor tricycle repacking become and both can hang trailer and engage in transport, can hang the agricultural tricycle that farm implements are done tractor-ploughing again, Chinese patent CN1071210 discloses a kind of motor tricycle with transportation cultivated land function, device is installed in the vehicle seat lower right side if this car owner will plow, the the rising and falling of device of plowing is to move realization by manpower, thereby tricycle may because of about uneven produces vibration, simultaneously, owing to manpower is moved the device that plows that rises and falls, thereby seem heavy, the operation effort.
The purpose of this utility model provides a kind of simple in structure, easy to operate, laborsaving, steady behind the agricultural motor tricycle frame of being suspended on, the agricultural tricycle tractor-ploughing suspension arrangement that tilling depth is adjustable.
The purpose of this utility model is achieved in that
A kind of agricultural tricycle tractor-ploughing suspension arrangement, it mainly comprises the drawing pull bar that is fixed on the vehicle frame back axle, drive the lift arm that drawing pull bar is risen and fallen, its lift arm links to each other with the oil cylinder expansion link of hydraulic jack and lifting thereupon, be connected with the ploughshare tripod in the drawing pull bar rear end, the depth of a ploughshare angle of penetration control lever with the farming of control ploughshare also is housed between ploughshare tripod and vehicle frame.
Lift arm by about two lift arms drive respectively about two drawing pull bar, lift arm is two joint hinge lift arms, one horizontal rotating shaft is housed on the vehicle frame, lift arm upper end is fixed on the rotating shaft upper and lower end and is fixed on the drawing pull bar, and the oil cylinder expansion link is fixed on connecting rod in the rotating shaft by one and is connected with rotating shaft and rotating shaft is stretched with expansion link and rotate.
Can adorn a tranverse connecting rod between two lift arms, the oil cylinder expansion link directly is fixed on the tranverse connecting rod.
Good effect of the present utility model is:
1, simple in structure, easy to operate, laborsaving, only need the operating grip on the control oil circuit distributing valve can realize farming.
2, the purposes of exploitation agricultural motor tricycle makes a tractor serves several purposes, and the peasant only need buy a tricycle can realize busy farming season tractor-ploughing, transportation in slack season.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Accompanying drawing is a structural principle schematic diagram of the present utility model;
By accompanying drawing as can be seen the utility model utilize original oil pump 9 on the agricultural motor tricycle vehicle frame, the oil circuit distributing valve 10 that has operating grip 11 and the hydraulic jack 5 that communicate are with it made the lifting power source, on vehicle frame, adorn a tractor-ploughing suspension arrangement, its device mainly comprises the drawing pull bar 3 that is fixed on vehicle frame back axle 8, drive the lift arm 7 that drawing pull bar 3 is risen and fallen, lift arm 7 by about two lift arms drive respectively about two drawing pull bar 3, lift arm 7 is two joint hinge lift arms, one horizontal rotating shaft is housed on the vehicle frame, lift arm 7 upper ends fixedly are connected in the rotating shaft, the lower end is fixed on the drawing pull bar 3, oil cylinder expansion link 6 is connected in by a connecting rod and makes rotating shaft with expansion link 6 flexible rotations in the rotating shaft, connect a double-share tripod 1 in drawing pull bar 3 rear ends, one ploughshare angle of penetration control lever 4 also is housed between double-share tripod 1 and the vehicle frame, and the flexible of control lever 4 changes to change the degree of depth of ploughshare farming the ploughshare angle of penetration on the tripod.
Operation principle of the present utility model is:
Diesel engine drives the oil pump rotation, the output oil of oil pump is input into oil passage control valve, by operating grip the oil transportation road is connected, hydraulic oil enters oil cylinder, along with in-oil cylinder oil mass increases, expansion link rises, and drives turning cylinder by connecting rod and rotates, along with rotating shaft rotation lift arm moves up, drive drawing pull bar simultaneously and move up, drawing pull bar drives the ploughshare tripod and ploughshare lifts, and ploughs this moment to stop, when making oil return line, connects operating grip, then oil cylinder begins emptying, and along with the minimizing of oil mass, expansion link falls to driving the rotating shaft counter-rotating, lift arm falls thereupon, drawing pull bar, the double-share tripod, double-share falls, and ploughs from newly, and close oil transportation and oil return two-way by operating grip this moment, double-share is lifting no longer, and the arable land can be carried out always.
During slack season, this device unloaded load onto trailer and can engage in transport and increase peasant's income.
