Abstract
The utility model relates to a hydraulic transmission device for discharging the maize in a maize cob collecting box of a shoulder carried harvester. A cover of a hydraulic lift is provided with an integrated package and a hand-operated reversing valve on the basis of a hydraulic hitch system of an original tractor, and tilting discharging work of a maize cob collecting box can be conducted as long as two high-pressure oil tubes and a discharging oil cylinder. Pressure oil is introduced to the integrated package by an oil supply pipe and a sealing ring of an original tractor. Returned oil flows back to an oil tank through an annulus surface of the outer wall of an original oil supplying tube. The hand-operated reversing valve is provided with a positioning mechanism which has the functions of automatically resetting, positioning and locking. The utility model has the advantages of simple structure, saves space, low cost and convenient installation.
Description
The utility model relates to a kind of hydraulic transmission of the Backpack-type maize grain header maize cob collector discharging that combines with tractor.
Existing Backpack-type maize grain header maize cob collector device for discharging, be outside the tractor hydraulic suspension, to set up the hydraulic system that a cover fuel tank, oil filter, oil pump, overflow valve, pipeline, hand-operated direction valve, high-pressure rubber pipe, oil cylinder and attended operation device etc. constitute again, fruit ear is filled the back and is made certain fringe case inclination flip by this system, and fruit ear is unloaded.The clear-cut use simple tool that has takes the method for machinery to unload fringe.
The purpose of this utility model provides the hydraulic transmission of a kind of Backpack-type maize grain header maize cob collector discharging, under the situation that does not influence the original hydraulic lift system performance of tractor, by the part Hydraulic Elements of suspension, finishes the discharge operation of maize cob collector.Compared with prior art, can save elements such as fuel tank, oil filter, oil pump, overflow valve, pipeline.
The purpose of this utility model realizes as follows: at former tractor by fuel tank, oil filter, control valve, oil pump, overflow valve, on the basis of the hydraulic lift system that hanging oil cylinder is formed, cover assembly that constitutes by integrated package and hand-operated direction valve of installation at the tractor hydraulic lift, fuel feed pump is connected with the import of integrated package pressure oil after the sealing ring sealing, the oil return opening of integrated package is connected the hydraulic oil oil sump tank that makes backflow through the annulus area of back oil road and fuel feed pump outer wall, oil-out of integrated package is connected with the hydraulic fluid port of the rodless cavity that is communicated with hanging oil cylinder that the tractor hydraulic lift covers, this oil-out is also connected by the rod chamber of high-pressure oil pipe and unloading fuel tank, the unload rodless cavity of material oil cylinder of another oil-out of integrated package, detent mechanism is housed on hand-operated direction valve, this detent mechanism can make hand-operated direction valve be positioned and pump the position that oil-feed port that hydraulic fluid port is connected and oil-out on the integrated package are communicated with all the time, and this oil-out is communicated with the rodless cavity of hanging oil cylinder and the rod chamber of unloading fuel tank on the integrated package, thereby make hydraulic lift hitch be in the lifting state, maize cob collector is horizontal, so that the Backpack-type maize grain header is walked on road.
The hydraulic transmission of this Backpack-type maize grain header maize cob collector discharging owing to used the part Hydraulic Elements of former tractor hydraulic suspension dexterously, simplifies the structure, and has saved the space, has reduced cost, and has made things convenient for installation.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the hydraulic circuit figure of the hydraulic transmission of the utility model Backpack-type maize grain header maize cob collector discharging.
Fig. 2 is the structural representation of integrated package (4) and tractor binding site in the hydraulic transmission of the utility model Backpack-type maize grain header maize cob collector discharging.
With reference to Fig. 1, Fig. 2, former tractor hydraulic suspension is made up of fuel tank (gearbox) 11, oil filter 12, control valve 10, oil pump 9, overflow valve 8, hanging oil cylinder 7.The design is on the basis of former tractor hydraulic suspension, the assembly of an integrated package 4 and hand-operated direction valve 1 is installed in its oil pipe gland position, increase by two high-pressure oil pipes 6 and a unloading fuel tank 5 again, under the situation that does not influence original tractor hydraulic suspension behavior, can carry out the maize cob collector discharge operation easily.
In installation process, the oil pipe gland of tractor to be pulled down, with two bolts 13 integrated package 4 is fixed on the tractor hydraulic lifting cover 15, fuel feed pump 17 on the former tractor is connected through the pressure oil import P of sealing ring 16 sealings with integrated package 4, the pressure oil of oil pump 9 has been introduced integrated package 4 like this, the oil return opening O of integrated package 4 connects through the back oil road 14 and the annulus area 18 of fuel feed pump 17 outer walls, and with sealing ring sealing, the oil return annulus area 18 that passes through back oil road 14 and fuel feed pump 17 outer walls flows back to fuel tank like this.The hydraulic fluid port of the rodless cavity C that is communicated with hanging oil cylinder 7 on the oil-out B of integrated package 4 and the tractor hydraulic lifting cover 15 is connected, and connects by the rod chamber H of high-pressure oil pipe 6 with unloading fuel tank 5, the unload rodless cavity of material oil cylinder 5 of another oil-out A of integrated package 4.Being designed to of unloading fuel tank 5: discharging when the rodless cavity fuel feeding, during rod chamber H fuel feeding, maize cob collector returns to horizontal level; During the rodless cavity C fuel feeding of hanging oil cylinder 7, suspension arrangement promotes, and when rodless cavity C took back oil circuit, suspension arrangement descended under action of gravity, and like this, when maize cob collector was horizontal, its pressure oil circuit of lifting hydraulic lift hitch can not disturb mutually.Detent mechanism 3 is housed on hand-operated direction valve 1, hand-operated direction valve 1 is had automatically reset and the function of position and lock.
Handle the handle 2 of hand-operated direction valve 1, can obtain the valve function of E, F, three positions of G.When hand-operated direction valve was in the F POF, A, B mouth were closed, and P, O mouth are connected, and pressure oil is by the internal duct oil sump tank, and the piston of unloading fuel tank 5 can rest on any position in the stroke.When hand-operated direction valve 1 was in the E POF, pressure oil led to A from P, and oil return is led to O from B, and unloading fuel tank 5 is under the effect of pressure oil, and piston rod stretches out, and made the discharging of maize cob collector inclination flip.When hand-operated direction valve 1 is in the G POF, pressure oil leads to B from P, oil return is led to O from A, unloading fuel tank 5 is under the effect of pressure oil, piston rod is return, maize cob collector returns to original horizontal level, when the Backpack-type maize grain header is walked on road, pressure oil leads to B from P, and hanging oil cylinder 7 piston rods stretch out, and hydraulic lift mechanism rises, rotation positioning device 3 is locked in the G POF with reversal valve handle 2, can make pressure fuel pump oil constantly be sent to hanging oil cylinder 7, hitch can not fall under the effect of weight, with the safety guaranteeing to use with reliable.
