Description

[Detailed explanation of the idea] The present invention relates to a rice straw harvester.

In order to collect high-quality rushes, this type of harvester is designed to sort out rushes that are less than a set length as waste during harvesting.

However, in the past, in general, the waste grass was released in a state where it dripped down one after another, and it was difficult to corrode and return to the field even if left as it was, so the released waste grass was collected separately. They had to be collected, which required a great deal of effort.

In view of the above points, the present invention aims to make it possible to efficiently collect waste grass.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

A reaping device 2 for reaping planted grass introduced between a pair of left and right dividing draft inner devices 1, 1 protruding forward, elastically clamps the reaped grass near the base of the plant and conveys it toward the upper rear side. An elastic clamping and conveying device 3, which prevents the tip side of the rush being conveyed by the conveying device 3 from moving backward, locks the portion halfway in the direction of the culm upward while forcing the root of the plant to move. A pair of front and rear locking conveyance devices 5 transport and change the posture of the rush grass to a horizontally fallen position, a lateral transport device 6 that clamps and transports the rush grass in the horizontal direction of the machine body, and a grass transporter that transports the grass in the lateral direction.
A sorting section 7 that removes waste grass that is less than a set length, and a collection section 8 that collects the selected high-quality grass, are sequentially mounted on low-pressure tire wheels 9 and a driving section 10 is extended in front. It is connected to the body of the vehicle, and is equipped with a rice grass harvesting machine that cuts and collects grass as it travels.

The sorting section 7 has combing protrusions 12 distributed over a predetermined width from the transport start end side of the lateral transport device 6 on the outer surface of an endless rotation band 11 that is rotatably provided in the longitudinal direction of the machine body. ... is provided protrudingly, and the collecting portion 8 is configured to have a smooth surface,
In addition, a feed roller 13 is provided at the rear of the portion corresponding to the smooth surface, and is configured to comb the rushes sent by the pinching conveyance device 3 and the locking conveyance device 5 to a set length that is not pinched by the horizontal conveyance device 6. At the same time, the entangled grass, etc. of less than 100 cm is transferred rearward, and the waste grass, etc. that are forcibly transferred through the rollers 13 are selectively removed, and only high-quality grass is collected by the collecting section 8.
It is my responsibility to make sure that they are collected.

At the rear of the sorting section 7, there is a front-backward facing portion 14b.

U-shaped support frame 1 having a horizontal portion 14b and a horizontal portion 14a
4, there is provided a storage section 17 in which a receiving section 16 is formed by attaching a belt-shaped sheet 15 made of a deformable flexible material in a V-shape across the rear end (free end) and the vehicle body. The waste straw grass sorted by the sorting section 7 is stored therein so that it can be easily collected later.

It is located close to the lower rear end of the elastic clamping and conveying device 3, and is connected to the outer surface of the rotation band 11, and is inclined so that it is located further down toward the rear and on the lateral sides farther from the rotation band 11. In this state, a discharge plate 18 is provided to receive the grass from the clamping and conveying device 3 to the rotating belt 11 so that the soil, etc. that falls during the transfer is guided to one side of the machine so that it falls. It is.

The support frame 14 has its proximal end attached to the machine body so as to be rotatable around the horizontal axis 1, and from the operating position behind the sorting section 7,
As shown by the two-dot chain line in FIG. 1, it is designed so that it can be rotated forward and changed to a non-operating position that covers a part of the upper part of the rotating band 11 of the sorting section 7.

A visible strip-shaped sheet 15 constitutes the storage section 17.
The material is not limited to a cloth-like material, and for example, a net or the like may be used.

In summary, the straw harvester according to the present invention is provided with a storage section for storing waste straw grass behind a sorting section for sorting waste straw grass, and the storage section is supported by a U-shaped support projecting rearward from the machine body. It is composed of a frame, and a belt-shaped sheet that extends between the free end side of the support frame and the fuselage body in the shape of a letter ``■'' when viewed from the side, and the support frame is rotated about its base end around a horizontal axis. It is characterized by being able to be freely switched between a use position in which it protrudes to the rear of the machine and a non-use position in which it is rotated to the front of the machine and covers the upper part of the sorting section.

In other words, since the selected waste grass is collected into the storage section 17, it can be discharged appropriately when it is full, so that the waste grass can be intermittently released into the field in the form of clumps. , they can now be collected more efficiently.

In constructing the storage section, since the storage section is opened on the side, compared to, for example, constructing a bag for storing waste grass, it is possible to push out lumpy waste grass from the side. Alternatively, it can be pulled out and released, making it easier to release than when taking out from above like a bag for storing waste grass, or when taking out by repeatedly pulling the bag.

Furthermore, when the storage section is not in use, the waste grass sorting section can be covered with a band-shaped sheet, so there is an advantage that the band-like sheet for storing waste grass can be used as a cover sheet for the sorting section.
