Abstract
The invention discloses a radiating device of an automatic protection hydraulic loop of a spreading machine, belonging to the field of the spreading machine. The radiating device comprises a radiator, a first oil inlet, a first oil outlet, a second oil inlet, a second oil outlet, a one-way valve and an oil pipe, wherein the left end and the right end of the radiator are connected with the first oil inlet and the first oil outlet respectively; the second oil inlet is connected with the one-way valve; an oil outlet of the one-way valve is connected with the second oil outlet through the oil pipe; the second oil inlet is communicated with the first oil inlet; and the second oil outlet is communicated with the first oil outlet. The radiating device has the beneficial effects of reducing back pressure of returned oil of the hydraulic loop, protecting a hydraulic system and enhancing a radiating effect of the radiator.
Description
Technical field
The present invention relates to a kind of paver product, relate in particular to the sink that a kind of paver is protected oil hydraulic circuit automatically, belong to the paver field.
Background technique
Paver is a kind of asphalt evenly to be paved on roadbase, and carries out the machinery of preliminary jolt ramming and leveling.Paver in the moment that starts work, the oil circuit of each system all will be got back to radiator simultaneously, can produce larger back pressure, as easy as rolling off a log hydraulic system is caused damage, and the radiating effect of radiator is descended, and causes returning-oil temperature too high.
Summary of the invention
Problem for above-mentioned prior art exists the invention provides the sink that a kind of paver is protected oil hydraulic circuit automatically, has back pressure, the protection hydraulic system that reduces the oil hydraulic circuit oil return, the radiating effect that strengthens radiator.
To achieve these goals; the technical solution used in the present invention is: a kind of paver is protected the sink of oil hydraulic circuit automatically; comprise radiator, the first filler opening, the first oil outlet; the two ends, the left and right sides of radiator connect respectively the first filler opening and the first oil outlet; also comprise the second filler opening, the second oil outlet, one-way valve, oil pipe; the second filler opening connects an one-way valve; the oil outlet of one-way valve is connected with the second oil outlet by oil pipe; the second filler opening and the first filler opening communicate, and the second oil outlet communicates with the first oil outlet.
The invention has the beneficial effects as follows: the heat radiation of the back pressure of reduction oil hydraulic circuit oil return, protection hydraulic system, enhancing radiator.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is partial side view of the present invention;
Among the figure: 1, radiator, the 2, first filler opening, the 3, first oil outlet, the 4, second filler opening, the 5, second oil outlet, 6, one-way valve, 7, oil pipe.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the present invention includes radiator 1, the first filler opening 2, the first oil outlet 3, the two ends, the left and right sides of radiator 1 connect respectively the first filler opening 2 and the first oil outlet 3, also comprise the second filler opening 4, the second oil outlet 5, one-way valve 6, oil pipe 7, the second filler opening 4 connects an one-way valve 6, the oil outlet of one-way valve 6 is connected with the second oil outlet 5 by oil pipe 7, and the second filler opening 4 and the first filler opening 2 communicate, and the second oil outlet 5 communicates with the first oil outlet 3.
Owing to be provided with an one-way valve 6 and oil pipe 7 at in-line more; in the time of can making the system circuit oil return in the too high situation of back pressure; pressure oil is opened one-way valve 6; get back to the second oil outlet by oil pipe 7; get back at last fuel tank, can reduce the oil hydraulic circuit oil return back pressure, protection hydraulic system, strengthen the heat radiation function of radiator.
