Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an improved structure of a handling chamber supply port in a threshing machine.

(b) Conventional technology In a threshing machine, the grain culm is fed into the handling chamber from a supply port opened on the entrance side of the handling chamber, and the base of the husk is held between a foot chain and a clamping rod installed opposite to it. In conventional threshing machines, the supply port is provided in a fixed state that always maintains a constant opening area.

(c) Problems that the invention attempts to solve If the supply port is set in a fixed state (opening area unchanged) as in conventional threshing machines, when the amount of husk increases significantly, the amount of grain culm is limited. Grain culms may become stagnant or clogged as grains are supplied in a rush to the supply port with an opening area, and
If the supply port is set with a large opening area that can accommodate a large amount of grain culm, stagnation and clogging of the grain culm can be prevented, but conversely, when the amount of grain culm is small, grains are lost by scattering through the gap. The problem is that there are too many.

In order to solve the above-mentioned problems, the present invention provides a means for solving the problem by replacing at least a part of the plate located at the side edge of the opening of the handling chamber supply port with a corresponding supply. It takes the form of a movable plate that can move toward and away from the other side wall of the opening of the mouth, and the movable plate has a part that closes or opens the supply port, and is installed opposite to the foot chain to adjust the supply weight by increasing or decreasing the supply weight. The movable plate body is connected to a movable clamping rod so as to be freely interlocked with each other.

(e) Function Therefore, according to the present invention, when the clamping rod moves according to the weighed amount of feed, the movable plate moves in conjunction with this, and when the weighed amount is large, the opening area of the feed port is widened, and the culm is The feeding operation can be carried out without causing stagnation or clogging, and when the amount of culm supplied decreases, the movable plate moves in the direction of reducing the opening area as the clamping rod returns, and the grains are This prevents it from scattering outward from the handling room.

(F) Example Next, the example shown in the drawings will be explained. The figure shows the case where the present invention is implemented in the supply plate section extending outward from the lower part of the supply port in an upper chain type threshing machine. , illustrated.

A shows a threshing machine, and a foot chain 3 is installed upward along the side of the handling room in which the handling barrel 5 is installed.
The armresting rod 4 installed below is composed of two parallel rods 4a and 4b, and each support rod 6 is vertically disposed at regular intervals from the armouring rod 4.
is mounted on a clamping stand 8 via a spring 7 so as to be able to move vertically, so that the starting ends of the foot chain 3 and the clamping rod 4 extend outward from the supply port 1 on the entrance side of the handling chamber. The structure is the same as the conventional structure.

The supply plate 2, which is connected to the lower edge of the opening of the supply port 1 and extends outward, is divided into a front plate part 2a and a rear plate part 2b, and is separated from the foot chain 3 side to the tip side of the culm. The front plate part 2a that supports the front plate part 2a has a mounting piece 9 bent on one side thereof and is fixed by joining it to the outer surface of the inlet side plate 10 below the underline of the supply port 2. and the end of the front plate part 2a are rotatably connected by hinges 11, 11, and a torque spring 12 is interposed in the shaft parts of the hinges 11, 11, so that the rear plate part 2b is connected to the supply port. A refracting piece 13 is installed so as to be pressed toward the upper edge of the opening of the rear plate part 2b, and a refracting piece 13 is installed on the inner side of the rear plate part 2b and can close the lower side of a part of the supply port 1 from the outside when moved upward. are integrally formed and configured.

In addition, an elastic body 1 such as cloth or a rubber plate is attached to the end of the rear plate portion 2b.
4 are connected by a stopper 15, and the other end side of the elastic body 14 is connected to the lower part of the inner rod 4a of the above-mentioned clamping rod 4 by a stopper 16.
It is fixed and configured by

Therefore, in a state in which the culm is being supplied, the clamping rod 4 moves up and down as shown by the arrow A in the same way as in the conventional type, and as it moves up and down, the rear plate portion 2b connected via the elastic body 14 moves up and down. It also rotates around the hinges 11, 11 and moves up and down as shown by the arrows.

During the threshing operation, when the husk is fed between the foot chain 3 and the ram 4, the rear plate portion 2b moves downward via the elastic body 4 as the culm 4 moves downward. Therefore, the portion of the supply port 1 facing the rear plate portion 2b is wide open, and the supply operation can be performed without causing culm, stagnation, or clogging.

In addition, when the culm is not being supplied, the rear plate portion 2b also moves upward as the trapping rod 4 moves upward, and the side portion of the rear plate portion 2b touches the lower side of a part of the supply port 1. It is closed to the outside to prevent paddy, etc. from scattering from inside the handling room to the outside.

(g) Effects of the invention As explained above, the present invention provides at least a portion of the plate located on the side edge of the opening of the handling chamber supply port as a movable plate that moves in the direction of expanding or contracting the opening area of the supply port. The movable plate body has a part that closes and opens the supply port,
This movable plate is configured to operate in conjunction with the operation of the clamping rod, so even if a large amount of supply culm is supplied to the supply port, it will automatically widen the opening area. Occurrence of clogging is prevented, and when the amount of husk supply decreases or there is no supply, the opening area of the supply port is automatically narrowed to prevent grains from scattering to the outside. It has the advantage of performing good threshing work and has the advantage of being able to be carried out suitably.
