Description
Technical field
The present invention relates to automobile-used auxiliary equipment technical field, more particularly to a kind of wheeled tractor are anti-sunken from lifting device.
Background technology
For tractor the soft terrains such as paddy field travel, often generation falls into car in operation process, this not only seriously reduces work effect
Rate, and it is easily damaged parts.In order to prevent tractor is slided from falling into, people often solve in terms of external environment condition and itself environment two
Certainly.
Solved from external environment condition, mainly improve tractor running environment, such as in plough, rake and rotary tillage process,
Poured water in field 3 to 5 centimetres of depths, the annual field band more subjobs of water of tractor, height flower tire stirs back and forth in field so that farming
Layer is more and more deeper, causes tractor to be sunk deeper and deeper, and at this moment external force can only be relied on to solve；When crossing ridge, pick is used as far as possible
Low ridge is dug to prevent ridge withstands tractor chassis and produces sliding fall into.For this solution method in the presence of wasting time and energy, operation difficulty is big
Deficiency.
Solved from itself environment, mainly set anti-trapping board in wheel is taken turns with forming anti-fall into, and this anti-wheel that falls into has one
Fixed effect, but it can not directly get over ridge and the walking of water channel and Lian Chi, and lacked in the presence of preventing that sunken ability, fault rate are high
Point.In addition, when tractor is sliding fall into when, this anti-wheel that falls into is difficult tractor is rolled pitfall away from, only saved oneself by piling or
Look for a powerful tractor to be drawn out pitfall, and can not lean on and itself roll pitfall away from.
The content of the invention
It is an object of the invention to overcome the above-mentioned problems in the prior art, there is provided a kind of wheeled tractor is anti-to fall into certainly
Lifting device, it can not only prevent falling into, additionally it is possible to when accidentally subsideing by itself rolling pitfall away from, realize " from ".
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions：
A kind of wheeled tractor is anti-to fall into from lifting device, including supporting steel plate below dilatory machine bottom board and located at tractor
Front-seat hydraulic means, preceding hydraulic pump control valve, heel row hydraulic means, rear hydraulic pump control valve in car body, the supporting steel plate
In the streamlined structure coordinated with base plate configuration, it is divided into using the forward and backward two parts being hinged, described front-seat hydraulic means one end
The propons of tractor is fixed on, the other end is connected to the forward part of supporting steel plate through bottom plate and hinge, correspondingly the rear discharge opeing
The back axle of tractor is fixed in pressure device one end, and the other end is connected to the rear part of supporting steel plate through bottom plate and hinge, before described
Between discharge opeing pressure device and preceding hydraulic pump control valve, heel row hydraulic means be connected between rear hydraulic pump control valve by hydraulic oil pipe,
The preceding hydraulic pump control valve, rear hydraulic pump control valve are also connected with the total hydraulic oil pipe of tractor.
Further, the front-seat hydraulic means, heel row hydraulic means respectively include two symmetrical hydraulic jacks.
Further, the lower surface of the supporting steel plate is shiny surface, can be reduced and mud ground friction, reduction tractor row
Walk resistance.
The beneficial effects of the invention are as follows：
The present invention realizes folding and unfolding by setting supporting steel plate, and using hydraulic means, does not interfere with the normally travel of tractor, both
It can effectively prevent front-wheel or rear skidding from falling into when needed；It can be realized certainly not against external force when front-wheel or rear skidding are fallen into again
Rise.

Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the present invention is described in detail.
Wheeled tractor described in the present embodiment is anti-to fall into from lifting device, as depicted in figs. 1 and 2, including located at tractor bottom
The supporting steel plate 2 of the lower section of plate 1 and the front-seat hydraulic means 3 in dilatory railcar body, preceding hydraulic pump control valve 5, rear discharge opeing
Pressure device 6, rear hydraulic pump control valve 7, the supporting steel plate 2 are divided into using hinge in the streamlined structure with the form fit of bottom plate 1
The propons of tractor is fixed in forward and backward two parts of connection, described front-seat one end of hydraulic means 3, and the other end is through bottom plate 1 and cuts with scissors
The forward part of supporting steel plate 2 is connected to, correspondingly the back axle of tractor, the other end are fixed in described one end of heel row hydraulic means 6
Through bottom plate 1 and be hinged and be connected to the rear part of supporting steel plate 2, between the front-seat hydraulic means 3 and preceding hydraulic pump control valve 5, after
It is connected between discharge opeing pressure device 6 and rear hydraulic pump control valve 7 by hydraulic oil pipe 4, the preceding hydraulic pump control valve 5, rear hydraulic pump
Control valve 7 is also connected with the total hydraulic oil pipe of tractor.
Further, the front-seat hydraulic means 3, heel row hydraulic means 6 respectively include two symmetrical hydraulic jacks
Top.
Further, the lower surface of the supporting steel plate 2 is shiny surface, can be reduced and mud ground friction, reduction tractor
Walking resistance.
The operation principle of the present embodiment is：
1st, when skidding is fallen into before needing to prevent or preceding skidding is fallen into when needing from：As shown in figure 3, hydraulic control valve before opening, and then
Bottom plate is promoted to move down, increase front portion and contact area of ground, so as to prevent anterior sagging or roll sagging front portion away from
Pitfall, realize from.
2nd, when needing to prevent rear skidding from falling into or rear skidding falls into needs from：As shown in figure 4, hydraulic control valve after opening,
And then promote bottom plate to move down, increase rear portion and contact area of ground, so as to the rear portion for preventing rear portion sagging or will be sagging
Roll pitfall away from, realize from.
3rd, when the sliding sunken needs of front and back wheel are from：As shown in figure 5, hydraulic control valve before opening, hydraulic control after opening
Valve, and then promote and move down before and after bottom plate, increase is anterior and rear portion and contact area of ground, from and sagging car body rolls away from
Pitfall, realize from.
