Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a self-propelled reaper, and more particularly to a conveyance mechanism for conveying an object to be cut in the self-propelled reaper.

[Conventional technology]

Mowing of soybeans and the like is performed manually or using a soybean reaper. As a bean mower, there is, for example, the one disclosed in Japanese Utility Model Laid-Open No. 60-104034.

This bean mower has two disc blades that cut the pea trunk in front of the main body that has been made to descend in the front and has wheels driven by a prime mover, and one disc blade is above the disc blade. Arranged is a bottomed cylinder that rotates with the blade. Several raising arms are attached to the eccentric shaft in the bottomed cylinder, and each raising arm projects radially from the hole in the peripheral wall of the bottomed cylinder, and each raising arm projects long as the bottomed cylinder rotates. It is designed to pull in and pull in. The disk blade and the bottomed cylinder are driven by a prime mover.

The bean trunk is guided between the two disc blades by the weeding rod, the raising arm is scratched up, and it is split and fed one by one between the disc blades, and the root of the bean trunk is cut. It is released to the side of the body. At that time, the raised arm at that position is retracted so as not to get in the way. The released bean trunk is then manually focused by the worker.

[Problems to be solved by the device]

However, in such a bean mower, the soybeans that enter the bean mower are raised by the arm and sent to the rear blade,
If it is incomplete, especially soybeans that have lodged or soybeans with a short stem length, it is easy for the stems to enter and get caught between the weed rods. The work had to be interrupted and inefficient. In addition, when removing the pinched stems, a large amount of shedding occurred, resulting in a large economic loss. Furthermore, when mowing fallen soybeans and the like, the mowing directions are disjointed and the particles are randomly emitted as they are, so it is very troublesome to focus them later.

This device is designed to ensure that even when cutting cut soybeans such as lodging soybeans or soybeans with a short stem length, the cut material is reliably conveyed by the blade and cut without being caught in the reaper. It is an object of the present invention to provide a transport mechanism for a self-propelled reaper that can be released in a state where it can be easily focused later.

[Means for Solving the Problems]

In order to achieve this object, the transport mechanism of the self-propelled reaper of this invention has the following structure. That is, two disc-shaped cutting blades (8, 8) are provided near the tip of the body (2) which is driven by the engine (3) and can travel.
In a self-propelled reaper that is arranged substantially horizontally so that 9) partially overlap, the transport mechanism has a bifurcated tip and extends from the front of the machine body (2) toward the rear while gradually narrowing, and Guide member (10) that is arranged so as to surround the cutting blade (9) and extend laterally, and a plurality of guide members (10) mounted on the shaft of one cutting blade (9) in multiple stages. Drive pulley (14,15) and this drive pulley (1
4,15) a plurality of driven pulleys (16,17,18) arranged in the front and lateral directions and paired with the driving pulley, and a part of the guide member between the driving pulley and the driven pulley. It has a conveyor belt (12, 13) for longitudinal feeding and lateral feeding arranged along (10).

The material to be cut may be soybeans, buckwheat, potatoes, rice, wheat or the like. The driving and driven pulleys and the conveyor belt may be arranged in three stages or more. A single conveyor belt may be used for both vertical and horizontal feeds, or the vertical and horizontal feeds may be separately provided for the conveyor belt.

[Action]

The material to be cut that has entered the machine body (2) from the front is guided between the guide members (10) by the conveyor belts (12, 13).
Forcibly guided vertically toward the cutting blades (8, 9) along the line, and the root of the cut object is cut by the cutting blades (8, 9), the guide members (10) are guided between the guide members (10). 10) along the conveyor belt (1
2, 13) is forcibly guided in the lateral direction and discharged outside the machine body (2) at a substantially right angle to the machine body (2).

The front part of the machine body 2 is bifurcated, and two disc-shaped cutting blades 8 and 9 are arranged in the vicinity of the bifurcation so as to be horizontally and partially overlap each other. Is driven by the power from the power distribution device 4 via a chain (not shown). At the tip of the bifurcated portion, a guide member 10 is attached which extends in the rearward handle direction while gradually narrowing in a bifurcated manner, and which is bent so as to surround the cutting blade 9 and extends laterally. 11 is a raising board.

In the portion surrounded by the guide member 10 and the raising plate 11, as shown in FIGS. 1 to 3, the conveyor belts 12 and 13 with protrusions, the driving pulleys 14 and 15 and the driven pulleys, which are arranged in upper and lower two stages, are provided. Pulley 1
6,17,18 are arranged, these guide member 10, conveyor belt 12,
13, the driving pulleys 14 and 15, and the driven pulleys 16 and 17 form a transport mechanism that transports the cut object.

The drive pulleys 14 and 15 are attached to the same shaft as the drive shaft of the cutting blade 9 and rotate at the same speed and in the same direction as the cutting blade 9. The driven pulley 16 is mounted on a shaft arranged in front of the driving pulley 14, and the driven pulleys 18, 17 are mounted vertically on a shaft arranged laterally of the driving pulley 14. The lower conveyor belt 12 is hung on a drive pulley 14 and driven pulleys 16 and 17 in a triangular shape, and the upper conveyor belt 13 is hung on a drive pulley 15 and a driven pulley 18.
