Description

[Detailed explanation of the idea] This invention relates to a corn harvester.

In a conventional corn harvester, the grain harvesting device and the conveying device are integrally fixed to the side of the tractor via a mounting arm, etc., and the ears harvested by the grain harvesting device are transferred to the rear of the tractor. It is formed so that it can be transported and stored on a trailer (or storage surface) that can be towed.

In other words, since conventional corn harvesters are integrated with a tractor, consumers have to purchase not only the corn harvester but also the tractor to which the corn harvester is attached, which is very expensive. It had become a thing.

Moreover, since the harvested ears are collected on a trailer that can be towed, their mobility, ie, turning ability, is poor, and they cannot be fully utilized in small fields.

Therefore, the present invention aims to solve the above-mentioned problem of poor mobility and to provide an inexpensive harvester that can be easily attached to and removed from a tractor. In addition to attaching the storage surface in a removable manner, a rice bowling device is provided protruding from the front end on the opposite side to the side where the storage surface is installed, and the rear part of the graining device and the storage surface are arranged in a planar shape. The gist of the structure is that the first conveyor and the second conveyor are connected, and the underframe can be integrally connected to the tractor by direct mounting with a three-point link.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
Reference numeral 1 denotes an underframe formed into a rectangular planar shape using a metal square pipe or the like. Wheels 2 and 2' are rotatably supported on both left and right sides of the underframe 1, so that the underframe 1 can run.

A storage surface 3 is mounted on a portion of the underframe 1 (the right half in the drawing), and the upper part of one side of the storage surface 3 is rotatably supported on a support arm 4 that is erected and fixed on the underframe 1. The storage box 3 is pivotally attached to the tip of a rod 5 of a hydraulic cylinder 5 whose base is pivotally supported on the support arm 4, and the storage surface 3 is rotated outward from the pivot point with the support arm 4 by the operation of the hydraulic cylinder 5. It is designed so that the stored items can be discharged onto the loading platform of a truck or the like by rolling in the opposite direction.

At the front end of the underframe 1 on the opposite side to the side on which the storage surface 3 is placed, a rice bowling device 6 is installed tilting downward, and the rear part of the grain bowling device 6 and the storage surface 3 mentioned above are attached. The upper surface opening is connected to a first conveyor 7 and a second conveyor 8 in the shape of a flat plane installed on the underframe 1, and the ears that have been scooped out by the ear scooping device 6 are transferred to the first conveyor 7 and the second conveyor 8. , are transferred and accumulated on the storage surface 3 via second conveyors 7 and 8.

The graining device 6 has a structure known today, that is, winding rollers 6-1962 are installed in parallel at predetermined intervals;
A stopper plate 6 2, 6 2 for mounting and holding the ears on which the winding roller 6-□*6 is mounted, and a gathering chain 6- provided on the stopper plate.
3.6-3 and front guides 64, 64, whereby the sweet corn stems and leaves that have entered between the left and right front guides 6-4964 are caught by the winding roller 6.
It is pulled towards the ground side (downward) by the rotation of 1,61,
The ears attached to the stem and leaves are separated from the stems and leaves because they are supported by the stopper plates 62-62, and the separated ears are moved to the stopper plates 62, 62 by the rotation of the gathering chains 6-3 and 6-3. The upper part of the grain is transferred to the rear part of the ear-picking device 6, and then transferred to the first conveyor 7.

The first conveyor 4 connected linearly to the rear of the earing device 6 is constituted by a belt conveyor or the like, and the second conveyor 8 is constituted by a packet type conveyor so that the grains can be lifted and transferred from above. It has become.

Furthermore, since the upper end of the second conveyor 8 extends into the upper opening of the storage surface 3, the conveyor S is placed at the lower position in order to escape in a direction that does not prevent the transfer of the storage surface 3. It has a bendable shape, and furthermore, a support rod 9 is integrally fixed and protruded upward at the upper end of the conveyor 3, and this support rod 9 prevents the storage surface 3 from rolling upward. By orthogonally abutting and engaging, the second conveyor 8 is prevented from returning to its original position before the storage surface 3 returns, and as the storage surface 3 returns, it gradually moves downward, and the second conveyor 8 The upper end of the storage surface 3 is returned to a position where it looks into the upper opening of the storage surface 3.

10 is a spring for automatically returning the bendable conveyor to its original state.

11. 12 and 13 are connecting members to the tractor fixed to the underframe 1. The connecting member 11 is attached to one upper link 14 attached to the tractor 18, and the connecting member 11 is attached to two lower links 15.
．． 16 is connected to the connecting members 12 and 13 respectively, and the two lower links 15 and 16 are moved up and down by a hydraulic device via a lifting arm and a lifting link.
The vertical movement and support position of the harvester can be controlled.

In addition, the drive source of the hydraulic pump 17 for rolling the storage surface 3 in the harvester of this invention and the drive source of the earing device 6 and the first and second conveyors 7 and 8 are from the circular axis of the tractor 18. It is something to take out.

In the figure, 19 is a speed reducer, and 20 is a clutch.

Since the corn harvester of the present invention has the above-described structure, it can be easily installed on an existing tractor, and since the corn harvester is directly mounted with a three-point link, the harvester can be integrated with the tractor. The tractor and harvester have good maneuverability, that is, turning ability, and can turn around easily, making them ideal for working in small fields.

Moreover, since the harvester has a removable storage surface on the underframe, it is possible to reliably collect and store the ears separated from the stems and leaves. It can be easily transferred to
