るようにせんとするものである。[Detailed description of the invention] The present invention consists of a lower grain culm holding and transporting endless belt and an upper clamping rail in which this endless band is elastically biased. A straw clamping and conveying device consisting of an endless belt for retaining and conveying the upper discharged straw and a lower clamping rail that is elastically biased against the endless band is provided, and a straw clamping and conveying device is provided below the terminal end of the straw clamping and conveying device. Regarding the conveyance structure of agricultural machinery equipped with a threshing device equipped with a waste straw processing device, the transfer of waste straw from the grain culm holding and conveying device to the waste straw holding and conveying device is always good regardless of the increase or decrease in the amount of waste straw conveyed per unit time. In addition, the purpose is to enable the supply of waste straw to the waste straw processing device with less disturbance in the posture and in a good manner.

のであるが、次に述べる問題があつた。 The above-mentioned conveying structure has the grain culm holding and conveying device configured in such a manner that the endless belt is positioned below, so that the grain culm can be received well at the starting end, and at the same time, the grain culm holding and conveying device is configured such that the endless belt is positioned below. In this method, the endless belt is positioned upwardly so that the waste straw can be effectively dropped and discharged at the end of the belt, but the following problem arises.

大きく増加した際に、これを円滑に受渡し搬送し
難いものとなり、排ワラ詰りを生じる等の搬送ト
ラブルを起す虞れがあるとともに、搬送構造自体
を損傷させてしまう虞れがあつた。 In other words, when arranging the endless belt in each of the two conveying devices, the upper surface of the endless belt for conveying grain culms and the lower surface of the endless belt for conveying waste straw must be at the same height or approximately the same height, and the grain culm conveying By bringing the end of the endless belt for waste straw and the start of the endless belt for conveying waste straw close to each other, even when the amount of waste straw conveyed per unit time is small, the transfer of waste straw from the grain culm holding conveyance device to the waste straw holding conveyance device is possible. However, with this arrangement, the width of the path through which the waste straw passes between the end of the endless belt for transporting grain culms and the start of the endless belt for transporting waste straw becomes quite narrow. When the amount of waste straw conveyed per unit time increases significantly, it becomes difficult to smoothly transfer and transfer the waste straw, which may cause transportation troubles such as clogging of the waste straw, and may damage the conveying structure itself. There was a risk that it would happen.

る機構を組込んであることを特徴とする。 The present invention has been made with the above-mentioned problems in mind, and in the conveying structure of an agricultural machine equipped with a threshing device having the above-mentioned structure, the entire endless band for conveying the removed straw is connected to the clamping rail for conveying the removed straw. It is characterized in that it incorporates a mechanism that elastically supports it so that it can be displaced upward with a biasing force greater than the elastic biasing force.

排ワラ挾持搬送装置終端から排ワラ処理装置への
排ワラ落差がほとんど変化しない。 In other words, when the amount of waste straw conveyed per unit time is small, the clamping rail for conveying the waste straw is moved downward to deliver and convey the waste straw, but if the amount of waste straw conveyed per unit time increases. The entire endless belt for conveying waste straw is also elastically displaced upward, and in this case as well, the waste straw can be delivered and conveyed in a good manner. As a result, the above-mentioned problems can be solved and the waste straw can always be delivered and conveyed in a good manner regardless of the increase or decrease in the amount of waste straw conveyed per unit time, which is a great practical advantage. Moreover,
The entire endless band for conveying waste straw is elastically displaced upward, and the elastic biasing force is larger than that of the clamping rail, so even if the amount of waste straw conveyed per unit time increases or decreases, the waste straw clamping Since the waste straw discharge height at the end of the conveying device does not change greatly, the height of the waste straw from the end of the waste straw holding and conveying device to the waste straw processing device hardly changes.

る。 Comparing this with, for example, an endless belt for conveying waste straw, where the end side is fixed and only the start end moves up and down elastically, in this case, as the amount of waste straw increases per unit time, at the end, Inevitably, the clamping rail will be pushed downward to a greater extent, and the straw discharge position will be lower accordingly.Conversely, when the amount of straw to be discharged decreases, the clamping rail will be pushed upward by the elastic force of the spring, and the straw will be discharged accordingly. Since the discharge position becomes high, an appropriate straw discharge height cannot be obtained, and the posture of the waste straw supplied to the waste straw processing device is disturbed. However, in the present invention, since the head is less likely to change as described above, the posture of the waste straw discharged to the waste straw treatment device is less likely to be disturbed, and there is an advantage that good waste straw treatment is possible.
