Description

[Detailed description of the invention] The present invention provides a transfer device that guides and feeds waste straw from a straw removal conveying device on the combine side to a tying machine in a combine harvester equipped with a straw removal and tying device, and particularly, This invention relates to improvements in support mechanisms for derivatives.

As shown schematically in FIGS. 1 and 2, a combine equipped with a straw removal tying machine has a tying machine A arranged and connected to the rear of the fuselage of the combine, and a straw removal conveying device on the side of the combine harvester. Straw removal deck 6 extends from the lower end of 3 to the tying machine A.
A straw removal guide 7 is arranged above the straw removal deck 6 at an appropriate distance, and the straw removal is carried out in the conveying path portion formed between the straw removal deck 6 and the straw removal guide 7. It is common to configure the device so that it is supplied to a binding machine.

By the way, most of the conventional combine harvesters equipped with a straw tying device have a straw scavenging guide installed above the straw scavenging deck at an appropriate distance and fixed to the combine body side, as shown in Fig. 2. Therefore, if a large amount of waste straw is brought from the end of the transport device to the start of the transport path, no measures are taken to pass the large amount of waste straw, resulting in stagnation or stagnation of waste straw. The problem is that it can become clogged.

Therefore, in order to prevent the above-mentioned straw stagnation and clogging, as shown in Utility Model Application Publication No. 49-13536N, the straw removal guide is mounted cantilevered on the binding machine side and directed toward the end of the conveying device. It is conceivable to leave the extending end of the straw in an unfixed state, but simply leaving one end of the straw expelling inducer in an unfixed state in this way does not make the straw expelling inducer durable and strong. If it were to be made into a solid object, the amount of elastic deformation would be insufficient and it would not be able to follow a large amount of waste straw.On the other hand, if it were to have a flexible structure that had sufficient followability, it would not only have poor durability, but also The free end of the straw removal guide will swing greatly from side to side, that is, in the direction of the straw removal culm, which will disturb the removal straw, and the relative position between the end of the straw removal conveying device and the guide will change greatly, causing the transfer. The problem arises that the condition deteriorates.

Therefore, the present invention is capable of properly tracking the supply of a large amount of waste straw and accurately preventing stagnation and clogging of the waste straw, while maintaining the waste straw derivative at a predetermined position. To provide a method in which waste straw can be reliably delivered and delivered from a conveying device to a conveying path without disturbance, and the durability is also significantly improved.

That is, in the present invention, the end of the straw evacuation conveyance device protrudes rearward from the center of the rear wall of the machine body, and the end of the straw evacuation guide constituting the straw evacuation conveyance device is connected to the rear wall of the machine body and behind it from the straw evacuation conveyance device. A straw tying machine that faces over a straw tying deck installed between a straw tying machine installed below and guides the slough discharged onto the straw tying deck to the tying machine and discharges it to the field. In the case of a combine harvester, the base end is fixed to the tying machine at a position above the knot guide body, the tip is a free end, and the upper support is located on the stock side of the straw removal conveying device and extends above the rear wall of the machine. , and a straw removal guide whose lower end is fixed to the nodule guide body, and the straw removal guide 7 is made of a member having a certain elasticity and has a tip portion 7.
b is fixed to the end 24a, which is the end of the upper support, to form a space that is approximately triangular in side view between the upper upper support and the lower straw removal guide, and is shifted to the left and right in plan view. The straw removal guide is positioned almost parallel to the straw removal deck in side view, and the middle part of the straw removal guide crosses the transfer path of the straw removal conveyance device 3 obliquely in side view, and the tip end is characterized in that it is constructed so that it is located above the straw removal guide end 4a and on the upper side in the transport direction.
