Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reaping and harvesting machine that pulls up and reaps planted stem culms, and because of its simple structure, the tip of the ear does not need to be strained by the lifting device even when mowing in the opposite direction, resulting in good performance. The purpose of the present invention is to provide a reaping/harvesting machine capable of recovering paddy.

Conventionally, with the above-mentioned cutting and harvesting machines, there has been a problem in which the seed part of the planted stem culm is squeezed by the lifting claw of the lifting device when mowing in the opposite direction, resulting in a lot of grain shedding and deteriorating the paddy recovery rate. Ta.

The present invention solves this problem by utilizing a weeding tool provided in front of the lifting device--which achieves the above objectives.

Next, embodiments of the present invention will be described in detail based on the drawings.

Fig. 1 shows an outline of the Koshibine, and has a steeply inclined pulling device 1 and a gently inclined pulling device 2, which are inclined upward and backward from near the ground, in the front part, and each of its lifting claws 1a, 2a, and so on. are placed side by side so that they overlap across the width of the aircraft, and this image raising device 1. It is constructed so that the planted stem culm A is locked and raised in two upper and lower stages by the cooperation of the grass.

A cutting blade 3 is installed below a position corresponding to the terminal end of the steeply slanted pulling device 1 and is pulled up to harvest the stumps of the planted stem culms that have been combed up.

Also, the gently inclined pulling device 2 is extended to the vicinity of the stem culm supply port 5 of the threshing device 4, and conveyed continuously from this extended point to the plant base! It is completed.

7. 7', 7' are weeding tools provided in front of the pulling devices 1, 2.

FIG. 2 shows the structure of the weeding tool 7, 7', 7''.

7. An inverted triangular weeding tool 7. A grass dividing tool 7, 7 having a width larger than the width of the pulling path C formed by the pulling devices 1, 2 is provided between the two dividing tools 7, 7'. Another weeding tool 7'' having substantially the same shape as B' is placed side by side with B' so that the upper part of the weeding tool 7'' becomes a width wedge.

In addition, the lower ends of the weeding tools 7, 7', 7'' are positioned near the ground and tilted backward and upward, and the upper ends are placed near the lower part of the sugar part of the planted stem culm A which is in an approximately upright position. The height of the location is Satoshi.

With this configuration, when mowing in opposite direction, the planted stem culm A is removed from the top of the weeding tools 7, 7', and 7'' as shown in Fig. 3.
The tip side is configured so that the receiver is stopped and placed within the raising system, and the plant base side of the planted stem culm A easily passes through the lower part of the weeding paths B and B', and the raising of both pulling devices 1 and 2 is carried out. It is constructed in such a way that it is well received.

Furthermore, this passing stock head side is gradually passed through the weeding paths B and B' by the pulling action of the steeply inclined pulling device 1 toward the tip side, and this seed part is removed from the weeding tools 7, 7', and 7. It is designed to eliminate the straining of the seeds by the weeding tool 7゜7', 7''.

Reference numeral 8 denotes a support rod for supporting one end of the curved weeding tools 7, 7', and 7'', and a horizontal rod portion 8a is provided above the seed portion of the cutting stem culm.

In summary, the reaping and harvesting machine of the present invention is provided with a plurality of lifting devices arranged at the front of the machine body, and in front of the lifting shaft formed by the lifting devices, from near the ground to the rear upper blade.
At the same time, the weeding tool is moved to the upper end in order to guide the tip side of the egg-cut planting stem culm upwards from the front side of the weeding tool Ω. and the width at the upper end thereof is larger than the width of the pulling path, and the upper end of the weeding tool is set lower than a part of the stem culm in a substantially upright position. It is characterized by

In other words, the planted stem culm A in each side is the weeding tool 7.7'
After the holder is stopped and corrected until it becomes approximately upright or leaning forward in front of the . The tip side is pulled up in good condition without being squeezed by the lifting claws of the lifting devices 1 and 2, and is harvested.

Furthermore, when the weeds are forced to pass through the weeding route B, there is no risk that the sugar part of the stem culms will be squeezed by the weeding tool 7.71, and there is an advantage that the stem culms with less shedding can be harvested.

Furthermore, in order to obtain such an effect, it is sufficient to simply modify the existing weeding tool as described above, and there is an advantage that it can be achieved by extremely simple structural modification.

In addition, as shown in FIG. 4, adjacent weeding tools 7, 7'.

7", a guide piece 9 that can be drawn out and whose position can be fixed freely is installed, and the width of the upper part of the weeding routes B and B' is adjusted according to the size of the culms and fists. It may be configured to change and adjust.

Further, as shown in FIG. 5, a guide rod-shaped spring body 10, which protrudes laterally and becomes larger upwardly, is placed on the mutually opposing sides of the weeding tools 7.7' and 7'', and the upper end is shaped like a free end. (Due to the rigidity of the planted stem culm A, when it closes this upper narrow part, the weeding path i; It can be made easier.

Incidentally, although numbers are written in the claims section for convenient comparison with the drawings, it is clear from the description that the present invention is not limited to the structure of the attached drawings.
