In addition, the wind by above-mentioned cooling fan 31 blows attracts the wind that is blown by engine blower 80 to come, and the interflow blows to body left side (left side of body direction of advance) then.

So, be located at the reaping part 4 on threshing apparatus 3 front sides, left and right sides sidewall 32, base plate 33 and rear wall 34 are set to constitute harvesting framework 35.Front end at sidewall 32 is provided with branch cursive script 36, the top of harvesting framework 35 be provided with to grab by the paddy stalk behind 36 fens grass of this minute cursive script into grab into cylinder 37, the below of grabbing into cylinder 37 is provided with cutter 38, and the rear side of cutter 38 is provided with the collected auger 39 of harvested paddy stalk.Continued on the rear wall 34 of the above-mentioned harvesting framework 35 top portion of carrying device 40, the final connection of carrying device 40 is on the shelling chamber 41 of above-mentioned threshing apparatus 3.Reaping part 4 is provided with reaping part pressure cylinder (omitting among the figure) up and down between above-mentioned harvesting framework 35 or carrying device 40 and above-mentioned organism frame 1, being integral shape with carrying device 40 can freely constitute with moving up and down.

Then, above-mentioned grabbing into cylinder 37, this rotating shaft 45 can before and after adjusting position be installed in the front end of a pair of arm 46.The base portion of arm 46 can be installed on the harvesting framework 35 with rotating freely, can install grabbing into the height of cylinder 37 with regulating.Rotating shaft 45 utilizes speed change gear 47 variable-ratio ground to transmit the rotation that above-mentioned engine 10 transmits.

At this moment, grab the rotation into cylinder 37, as shown in figure 11, the corresponding speed of a motor vehicle can improve rotating speed interimly, and its rotation ascensional range narrows down along with the speed of a motor vehicle becomes at a high speed.

That is to say, even body is in the traveling halted state, grab into cylinder 37 and rotate with regulation rotating speed a, rise to the words of speed of a motor vehicle B from the speed of a motor vehicle zero to the speed of a motor vehicle A of certain speed, will rise to the regulation rotating speed b of next step quickly, this regulation rotating speed b is kept before speed of a motor vehicle C rises to next switch speed to be close to necessarily, speed of a motor vehicle C rises to the words of next switch speed, make it to rise to the regulation rotating speed c of next step quickly, this process repeatedly, the regulation rotating speed of grabbing cylinder 37 presents among Figure 11 step-like, and from regulation rotating speed b to the ascensional range of regulation rotating speed c than from the ascensional range " greatly " of regulation rotating speed a to regulation rotating speed b.

Grab rotation into cylinder 37, the such speed change of rotational line L that the speed of a motor vehicle is as shown in figure 11 followed, so at low-speed region, grab into the rotation of cylinder 37 slack-off, stalk can be missed, at high-speed region, paddy stalk mobile slack-off will produce by atwirl grabbing into cylinder 37 and beat and the head loss of threshing.

The present invention, the rotational line L that follows for the speed of a motor vehicle, at low-speed region, (regulation rotating speed a～b) accelerate relatively reduces stalk and misses to grab rotation into cylinder 37.At high-speed region, the relative rotational line L that follows of the speed of a motor vehicle, (regulation rotating speed c～d) slack-off corresponding to moving of paddy stalk, suppressing because of the grabbing into beaing that cylinder 37 causes of rotation, thereby reduces the head loss of threshing to grab rotation into cylinder 37.

For above-mentioned situation, each stipulates that the rotating speed of rotating speed a, regulation rotating speed b, regulation rotating speed c～separately switches, because the rising of the speed of a motor vehicle is carried out at interval with certain approximately equal relatively, so can stablize switching.

So, grabbing rotation into cylinder 37 can constitute by step-like the switching time, utilize the height and position of grabbing into cylinder 37, can change and grab into the climbing that revolves speed of cylinder 37 etc.

That is to say, as shown in figure 12,, then be considered as standard paddy stalk pattern, switch successively and rotation is risen to certain regulation rotating speed from certain regulation rotating speed when grabbing height into cylinder 37 when being higher than specified altitude; When grabbing height into cylinder 37 when being lower than specified altitude, then be considered as short paddy stalk pattern, compare with above-mentioned standard paddy stalk, improve the initial setting rotating speed, ascensional range from certain regulation rotating speed to certain regulation rotating speed reduces than standard paddy stalk pattern, for short paddy stalk pattern, during the fastest speed of a motor vehicle, though rotating speed is approximate identical with standard paddy stalk pattern, before this will be to be rotated than the fast rotating speed of standard paddy stalk pattern.

Therefore, grab into cylinder 37, as long as reduce the height of grabbing into cylinder 37, the initial setting rotating speed improves, and the drum rotation speed speedup is forwards toppled over so can prevent short paddy stalk, reduces the head loss.

In addition, common paddy stalk or long paddy stalk are standard paddy stalk pattern, can prevent the head loss, thereby improve durability.

The height detecting device of grabbing into cylinder 37 constitutes for any, but among the embodiment, utilizes link mechanism that displacement transducers such as potential difference instrument are continued on arm 46.

Figure 13 is relevant other embodiment that grab into cylinder 37 rotation controls, before being lower than the regulation rotating speed of low-speed region, rise to certain rotating speed quickly and switch with step-like, the high-speed region surpassing the regulation rotating speed then rises pro rata with traveling speed (speed of a motor vehicle).

Therefore,,, grab and rise greatlyyer into the rotating speed of cylinder 37, miss so reduced the paddy stalk for the variation of the speed of a motor vehicle at low-speed region; At high-speed region, the relative speed of a motor vehicle is grabbed cylinder 37 and can not be surpassed and need more than the rotating speed, thus can prevent because of grabbing beaing of the paddy stalk that causes into cylinder 37, thus reduce head loss.
