Description

[Detailed description of the invention] [Industrial field of application] The present invention is used by being mounted on a combine harvester, etc.
Grain culms, which are held and conveyed in a sideways position by a feed chain, are introduced into the handling room and threshed, and the threshed product is passed through a sorting filter! 511 sumiyo ni layer line 1. When it comes to general curvature.

[Conventional technology]

Conventional threshing devices of this type are constructed so that a single handling cylinder with handling teeth protruding from the outer circumferential surface acts on the grain culm being clamped and conveyed.

[Problem that the invention seeks to solve]

However, in the case of the above 2, the diameter of the handling barrel itself needs to be large enough to accommodate the tip of the grain culm that is subjected to mechanical action, so it is inevitably large in diameter. Therefore, the threshing device itself must be bulky, and the grain tank must be installed on the side of the threshing device from the viewpoint of machine stability, which limits the tank capacity and makes it difficult to set and discharge grains. The drawback was that it had to be done frequently.

In order to solve this problem, a plurality of relatively small-diameter handling cylinders are arranged side by side in the direction of the culm in such a way that the handling teeth of adjacent handling cylinders are overlapped. It is conceivable to use a low-bulk device and place a grain tank above this threshing device to increase the tank capacity (Japanese Patent Application No. 100049/1983), but in this case, the grain culm subjected to the mechanical action However, if the angle of the handling teeth acting while rotating is centered on the direction perpendicular to the culm direction, the handling teeth will not have sufficient mechanical strength unless they are in an upright position relative to the culm. As a result, the space formed between adjacent handling cylinders deviates from the above-mentioned temporary action range and becomes a 7Pc part, which causes the problem that the grain culm corresponding to this part cannot receive sufficient mechanical action. be.

Furthermore, since the diameter of the handling barrel is relatively small, threshing products such as grain culms and straw waste are likely to become entangled, which may lead to a decrease in threshing efficiency.

An object of the present invention is to provide a threshing device that can efficiently thresh while keeping the threshing device itself low in bulk.

[Problem that the invention seeks to solve]

The characteristic configuration of the present invention is that a conveyance passage for grain culms, which are conveyed while being held in a tilted position by a feed chain, is formed in the upper part of the handling chamber, and handling teeth are provided on the outer peripheral surface of the lower side of this conveyance passage. The protruding endless belt is wound horizontally and driven so that its upper surface is directed toward the tip of the culm, and a sorting filter is installed along the locus of the tip of the handling tooth below the endless belt. , and a processing chamber is installed on the head side of the handling chamber to handle the threshed material in the upper part of the handling chamber, loosen it into pieces by a rotating body that is driven to rotate in the same direction as the rotation direction of the endless belt, and send it to the lower part of the handling chamber on the head side. Its functions and effects are as follows.

[For production]

■ Since the endless band with handling teeth is intended to exert mechanical action on the grain culm, the endless band can be set to a low-bulk state due to the arbitrary shape of the endless band, which reduces the installation space of the grain tank. can be expanded without damaging the fuselage or the lance.

Also, because it is an endless body, compared to a type that has multiple handling barrels,
@It is possible to add an uneven mechanical effect over the entire length of the culm,
Entanglement of grain culms can also be suppressed.

■ The threshing system is an upper plate type in which the grain culm conveyance path is set in the upper part of the handling room and the mechanical action and fir action parts can be separated, so the opening with the filter body is sufficient below the endless belt. A fir action can be added, and grain tailing processing can be carried out smoothly as well as leveling of grain threshing.

■ A rotating body is installed on the tip side 1 of the handling chamber, so
By loosening and dividing the threshed material, which tends to stay in the upper part of the handling chamber, by the rotating body, overload on the endless body and the handling teeth can be prevented, and the threshing process can be carried out smoothly.

〔Effect of the invention〕

As a result, we have been able to provide a product that can efficiently thresh and exhibit stable performance over a long period of time with little damage to the equipment.
