Abstract
A riding type transplanter having a water-cooled engine body (31) mantled with an engine cover (18). A motive power part (19) in which the said engine body (31), a cooling fan (32) driven by the said engine body, and a radiator (33) cooled by the said fan, are horizontally arranged, is provided in front of an operating part (17). It characterizes in the engine body (31), and the radiator (33) are mounted in landscape orientation of a carring man-stepping engine body (1) in a riding type transplanter.
Description
In the present invention relates to incite somebody to action the power part that covers engine with hood is housed, is configured in the riding type transplanter in operation portion the place ahead.
In the past, above-mentioned riding type transplanter was to utilize cooling air mode for the interior engine that is contained in the power part.
Recently, for riding type transplanter, along with the development of the less important work device of setting up multirow formula and additional fertilizer apparatus etc., working load increases day by day.Therefore,, wish to be equipped with high-power engine, for using water-cooled engine to study corresponding to the increase of load.
Generally, other riding-type agricultural machinery for the farm tractor that has been equipped with water-cooled engine, mower etc., the place ahead or the rear that are the engine body on the output shaft fore-and-aft direction are equipped with radiator, therefore employing can think that riding type transplanter also can adopt same engine assembling form with the form of the fan-cooled radiator of engine output driving.
, water-cooled engine when fore-and-aft direction disposes, engine, cooling fan, and the tandem result of radiator, make the power part front and back extend,, definite with respect to allocation position like this bridge, the front end of power part then extends to the place ahead of fuselage.That is, can predict for the driver, field of front vision worsens, and operability reduces, and power part prolongs to the place ahead in addition, and making when the fuselage conversion direction of field, just needs certain space by the fuselage lengthening, and promptly alleged tune ground strengthens.
The present invention is conceived to above-mentioned problem, and main purpose is, obviously improves the visual field situation of forwards seeing from the driver's seat, and reasonably disposes high-powered water-cooled engine under the prerequisite that do not extend before and after power part.
In order to achieve the above object, the invention provides a kind of riding type transplanter with water-cooled engine main body that hood covers, its power section is by above-mentioned engine main body, cooling fan by the engine main body driving, the radiator that is cooled off by said fans constitutes, this power part is arranged at the place ahead of bridge, above-mentioned engine main body and above-mentioned heat sink arrangements are on the lateral attitude of the manned traveling machine body of riding type transplanter, the bracing frame of engine wherein is set in the front portion of body, on this bracing frame, form the opening that above-below direction runs through, the part of above-mentioned engine main body bottom is installed on this opening.According to such formation because engine body, cooling fan, and radiator arrange at the horizontal direction of fuselage, engine integral body diminishes at the requisite space of fore-and-aft direction, the power part that this water-cooled engine is housed so also shortens in the length of fore-and-aft direction.
Therefore, can improve the visual field in driver the place ahead, and compare with the situation of vertical configuration engine, cooling fan and radiator, need not strengthen fuselage length and just can be equipped with high-powered water-cooled engine, this is favourable for the riding type transplanter that working load increases.
Generally, cooling fan is to dispose coaxially with the coolant circulation pump that is arranged on engine body top, so the radiator relative with cooling fan also is in high position certainly with respect to engine body, the structure that covers the hood of power part is to be made of the shape that does not influence radiator.In addition, the sight line that is positioned at body the place ahead that the driver at power part rear need see is the front lower place, so the height of power part front position can influence driver's the visual field, the height at power part rear portion does not influence driver's the visual field very much.
Therefore, when on the basis in above-mentioned setting with the skew of above-mentioned radiator and above-mentioned cooling fan when being configured in the rear of above-mentioned engine main body, because the present position, upper end of radiator is higher than the upper end of engine main body, be not partial to radiator and cooling fan and compare when the engine body rear is provided with, motorized hood front portion can be arranged to be in lower location status.That is to say, power part can be made the state that tilts to the front lower place more.
Therefore, engine can be made the good structure of field of front vision, further improve operating characteristics.
According to the solution of the present invention, can the whole low level of the engine ground configuration of radiator will be comprised.
For this reason, the power part that water-cooled engine is housed is the formation of low level, can further improve the visual field in the place ahead.
,, generally wish miniaturization as much as possible, but during as if the heat balance in insufficient consideration power part, be easy to become superheat state this moment, then can not give full play to the ability of water-cooled engine in order to constitute the good power part of field of front vision.
In order to solve above-mentioned problem, when above-mentioned radiator and above-mentioned cooling fan being offset above-mentioned engine main body when being provided with near exhaust manifold, make most of cooling air of radiator flow through the exhaust manifold configuration side of engine body, so the exhaust manifold of high temperature is cooled off by above-mentioned cooling air, the heat around exhaust manifold is detained minimizing.
By engine body and radiator and cooling fan are reasonably disposed, utilize the cooling air behind the cooling fan, the exhaust manifold of cooled engine body high-temperature portion is kept the heat balance in the power part well effectively, can give full play to the function of water-cooled engine.
And then, by arranged outside wind scooper, the cooling air by radiator is flowed effectively along the periphery wall of exhaust manifold at exhaust manifold, can interdict radiant heat with wind scooper simultaneously from exhaust manifold.
Its result can keep the heat balance in the power part more well.
In addition, according to the present invention, be connected on above-mentioned muffler on exhaust manifold by the blast pipe connection, be configured in and the lateral outer side of the above-mentioned power part of the above-mentioned radiator opposition side below of pedal up and down, simultaneously at the above-mentioned pedal up and down of the height middle part of quite above-mentioned radiator configuration, thus, the mobile wind path lower portion of the cooling air behind the cooling radiator places the below of pedal up and down.Cooling air also easily flows through the below of pedal up and down like this.Therefore, be provided in up and down the air cooling that also is cooled of the muffler of pedal below.
Above-mentioned effect has been played the cooling air that utilizes again effectively behind the cooling radiator, and has been cooled off muffler effectively, plays the effect that reduces exhaust noise.
In addition, according to the present invention, on the basis of above-mentioned setting, with above-mentioned muffler with the state configuration of exhaust rearward below above-mentioned pedal up and down, simultaneously the opening of the tail pipe on the above-mentioned muffler is positioned at the rear of the pedal installing hole on the above-mentioned pedal up and down.Like this, the exhaust of discharging from the muffler tail pipe can not flow to the top from the pedal installing hole of pedal up and down, enters bridge.Particularly the pedal installing hole away from tail pipe be provided in when starting pusher side, the gas of discharging can be spread at the position of square pedal installing hole far away by near the cooling air that muffler, flows.
The effect that prevents the bridge environmental deterioration has in advance been played in above-mentioned effect.
