Description

[Detailed description of the invention] The present invention consists of a reaping device, a device that conveys the stem side of the cut grass obliquely upward, and a device that changes the position of the harvested rush grass to a sideways position, and a device that transfers the head side of the grass that is in the sideways position. This invention relates to a rice straw harvesting machine equipped with a device that clamps and conveys and supplies the entire rice grass onto a sorting device.

In such a rice rush harvesting machine, only the tip side is held and the entire rice grass is conveyed and fed onto the sorting device, so the plant side tends to be delayed, and the rice grass is fed in an attitude inclined with respect to the picking direction of the sorting device. There is an inconvenience that can easily lead to troubles such as breakage or tearing of the rush, and as a countermeasure to this problem, conventionally, as shown in Fig. 4, the rush side is moved from the stem conveying device 3 onto the sorting device 4. Guide 1
1, and a rotary packer 12' that acts from below on the root of the rush plant on the guide 11 and forcibly conveys the root of the rush to the sorting device 4, but when using this, As is clear from the figure, when the picking car is located on the same plane as the picking belt of the sorting device, and in order to avoid contact between the picking car and the picking belt, the end of the feeding path by the picking car is naturally placed on the sorting device. Since a path portion having no feeding action is formed between the picker and the sorting device, which is located at a distance on the upper side in the feeding direction, grass, especially straw grass waste, stagnates in that path portion. As a result, the conveyance and supply of the rush to the sorting device is obstructed, and even though a packer is provided, the rush cannot be smoothly and reliably conveyed and supplied to the sorter. Since the tucking car acts in a direction that presses the base of the rush plant against the guide side, the tucking car does not release the grass from the tucking car at the end of the feeding path, causing problems such as being dragged under the tucking car. There was a simple drawback.

In view of the above-mentioned circumstances, the present invention is designed to smoothly and reliably transport and feed the root side of the rush plants onto the sorting device, and to transport and feed the rush plants onto the sorting device in a posture along the gradation direction of the sorting device. The aim is to ensure reliable and good selection.

The rice grass harvesting machine according to the present invention is provided with a guide that slides and guides the rice plant side from the plant conveying device to the sorting device, and at an upper position opposite to this guide, The present invention is characterized in that a device for conveying the device with its side fixed to the sorting device side is provided in such a state that its conveying terminal portion is located above the sorting device.

In other words, it is effective to utilize the fact that a device is provided at an upper position facing the guide to lock and transport the rice plant base side to the sorting device side, that is, the locking and conveying device is displaced upward with respect to the sorting device. Since the terminal end of the locking conveyance device is positioned above the sorting device, the straw grass waste on the root part of the strawberry plant and the guide can be moved through the locking conveyance device reliably and smoothly without stagnation. As a result, the rice grass can be transported and fed onto the sorting device in a manner along the direction along the edge of the sorting device without causing a delay in stock production. It has become possible to carry out the process smoothly, reliably, and safely without causing problems such as breaking or tearing the rush.

Hereinafter, an embodiment of the present invention will be described based on the drawings. The clipper-type reaping device 1 cuts the base of the planted rush grass, and the clipper-type reaping device 1 cuts the base side of the grass that has been cut, with the base side of the grass cutting ahead of the tip side. A stock transfer device 3 that changes the harvested straw grass to a sideways posture with the tip side facing forward in cooperation with a locking conveyance belt 2 that conveys the succeeding ears of grass upward by pinching and conveying them upward.
and a device 5 which holds the tip side of the rush that is lying on its side and conveys and supplies the entire rush onto the sorting device 4 from the side, and the sorting device 4 and the control device 6 are connected to a pair of left and right running wheels 7, fuselage frame 8 with 7
This is a rice rush harvesting machine attached to a rice straw harvester, and the sorting device 4 removes the rice grass of a set length or less from the supplied rice grass by means of a picking belt 4A that rotates in the front-rear direction perpendicular to the conveying and supplying direction. It is structured as follows.

On one side of the rush introduction path A to the reaping device 1, there is a weeding movement rod 9 which is tilted upward from the ground and can be driven and swung from side to side using its front end as a fulcrum.
A fixed weeding tool 10 is provided in front of the weeding rod 9.

The stock transfer device 3 is configured with a pair of clamping conveyance belts 3A, 3A, and the conveyance supply device 5 is also configured with a pair of clamping belts 5A, 5A. 5B in the figure is an auxiliary locking conveyor belt.

A plate-shaped guide 11 that slides and guides the straw root side from the root conveying device 3 to the sorting device 4
At the same time, at an upper position opposite to this guide 11, there is provided a locking and conveying device 12 using a belt with a protrusion that locks and conveys the root side of the rush plant to the sorting device 4 side, and its conveying end portion is placed above the sorting device 4. , that is, it is provided in a state where it is inserted into the center belt 4A,
And, the rear end side of the guide 11, the stock alignment plate 13
is erected and transported in an inclined position such that the closer it gets to the sorting device 4, the more rearwardly it is located.

In the figure, 14 is a collecting section for sorted straw grass.
