Description

[Detailed description of the invention] This invention smoothly guides and feeds the standing stem culm of corn after harvesting the corn without damaging it, cuts it from the root, and then chops it into appropriate lengths and harvests it for livestock. This invention relates to an improvement of a stem culm guidance feeding device in a shredding harvester for use as feed.

After the fruits have been harvested, the erect stem culms are guided backwards and cut using a guide feeding device, and the cut stem culms are cut into pieces of appropriate length using a windmill with a cutter, blown up, and collected at an appropriate location. A number of shredding harvesters have been developed that allow for use as feed for livestock.

By the way, in the case of the conventional stem culm guiding device, the clamping guides for pinching and guiding the erect culms backward while reliably separating the erect culms from other erect culms were all installed at intervals between the erect culms. It was fixedly attached to the inside of the left and right pair of guide frames to provide elasticity. Therefore, during stem culm guidance work, the incoming stem culm is forced to be guided under a pinched condition, which may result in more damage to the stem culm, or if the machine breaks down for some reason and stops operation, etc. In the first place, the stem culms that have passed between the clamping guides cannot be easily taken out from between the clamping guides, and the stem culms cut from the headland cannot be supplied between the clamping guides and collected in pieces. There are many disadvantages such as the erected stem culm being pushed down by the fixedly provided clamping guide, resulting in uncut areas, and there has been a strong desire to improve these problems.

In view of the above, in order to solve all of the above-mentioned drawbacks, the present invention uses the pressing operation of the stem culms inside a pair of left and right guide frames provided with a space between the stem culms to enter, so that they are directed toward each other in the pressing direction using the pivot shaft as the fulcrum. A pair of clamping discs which are slidably rotated freely and which are elastically restored to their original state when the stalk culm is pressed and released so as to close the stalk culm entry interval are positioned via the sliding arm, and are used to clamp the erect stalk culm. The present invention aims to provide a stem culm guiding and feeding device for a shredding harvester that not only improves the guiding efficiency but also can take out the guided stem culms, guide the pinching of stem culms cut from headlands, and prevent standing stem culms from being left uncut. The configuration of the device of the present invention will be described below with reference to various preferred embodiments shown in the accompanying drawings.

In the drawings, reference numeral 1 denotes an agricultural vehicle, and the agricultural vehicle 1 includes a chassis 2 on which a large number of wheels 3 are mounted, each of which is rotated simultaneously by a hydraulic drive, and a prime mover compartment 4 located at the front of the chassis 2.

After the agricultural vehicle 1 is removably attached, the agricultural vehicle 1 is moved through a corn field where only the fruits have been harvested, and at the same time, the shredding harvester 9 is operated. Then, as the agricultural vehicle 1 moves forward, the erect stem culm A is partitioned by the pair of left and right guide frames 13, 13, and enters into the stem culm entry interval 12. However, the pair of left and right guide frames 13,1
On the opposite inner side of 3, there are sliding arms 14, 14 which are supported so as to be able to slide around a pivot shaft 15, and a restoring machine 17... or 18 which always resiliently restores the sliding arms 14, 14 to the starting state. Since the pair of clamping discs 16, 16 suspended loosely are positioned so as to touch each other and sealing off the stalk culm entry interval 12, the pair of clamping discs 16, 16 are suspended by the pressing operation of the stalk culm A that has entered. 16, 16 are rotated in one direction by friction with the stem culm A, and slide from the state shown in Fig. 2 to the state shown in Fig. 4, or from the state shown in Fig. 6 to the state shown in Fig. 7, using the pivot shafts 15, 15 as fulcrums. Then, while holding the stem culm A comfortably, it is guided in an upright state as the agricultural vehicle 1 moves forward, and is fed into the rear supply rolls 10, 10, and at the same time is cut from the root part by the cutting device 11.
