Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a threshing machine outlet stuck grain collecting device for collecting grains stuck to waste straw discharged from the culm opening after being threshed.

(b) Prior art Conventionally, a binding device is arranged outside the culm outlet of a threshing machine to bind waste straw, and the grains attached to the waste straw are collected on the ear side of the guide plate of the binding device. There are already known devices equipped with a collection container for this purpose.

(c) Problems to be solved by the invention The prickly grain collecting device in the known threshing machine has the following features:
Since the collection container was attached to the threshing machine or a member integrated with it, when the tying device was moved toward the culm of the straw to change the binding position relative to the straw, the tying device was moved to the stock side or the ear side. If the movement is adjusted too much, the grains that fall from the ear side of the guide plate may not fall into the collection container and may fall on the ground.To eliminate this problem, the collection container must be made significantly larger. However, if the collection container is made large in size, it is difficult to perform the collection operation or to attach and detach the container.Furthermore, when the tying device is moved toward the ear side, the guide plate becomes an obstacle, making the collection or attachment and detachment extremely difficult. It becomes troublesome.

(d) Means for solving the problem The present invention provides a binding device that is movable and adjustable in the direction of the culm of the waste straw on the outside of the discharge culm, and the binding device is arranged so that it can be moved and adjusted in the direction of the culm of the waste straw. In a threshing machine equipped with a guide plate that is inclined so that the ear side is lower and extends near the ear side, a collection container is placed at the lower part of the ear side of the bundling device, and the collection container is placed in the lower part of the ear side of the guide plate and when the bundling device The collection container is configured to be removably attached so as to face the lower part of the panicle side of the discharge culm in a state of being moved to the origin side, and to move the collection container toward the culm of the discharge straw following movement adjustment of the binding device. This solved the above-mentioned problem.

(e) Action The waste straw discharged from the culm passes through the elastic plate and moves onto the guide plate of the bundling device.

During this time, the grains that have separated from the straw fall into the collection container on the ear side, and then move onto the guide plate on the stock side, and the grains that have separated from the straw on this guide plate are It passes over the guide plate, moves to the panicle side, falls into the collection container, and is collected.

Furthermore, when adjusting the bundling device toward the culm of the waste straw to change the bundling position for the waste straw discharged from the waste culm, the collection container is moved at the same time while attached to the bundling device. The positional relationship between the guide plate and the ear side end portion does not change, and grains falling from the guide plate can be accurately collected without omission.

Furthermore, when attaching or removing the collection container, not only when the tying device is set on the stock side, but also when adjusting the movement toward the ear side, the collection container is moving toward the ear side together with the tying device, so the guide plate can be easily attached and detached without causing any obstruction.

(f) Example An example of the present invention will be explained with reference to the drawings.
Reference numeral 1 denotes a threshing device mounted on a base 2 of a mobile threshing machine, in which a feed chain 4 is provided at the top of a handling port 3, a pinching rail 5 is provided at the bottom, and a binding device 7 is provided outside the culm discharge port 6. The binding device 7 has a knot 9 and a discharge arm 10 in the upper part of the collecting culm part 8, a packer 11 and a needle 12 in the lower part, and a door 13 on the discharge side. The guide plate 15 forming the lower surface of the collecting culm part 8 is connected to the gutter-like parts 15a, 1 from both sides of the chain case 14 which transmits power to the nodule shaft.
5b and protrudes downwardly toward the panicle side.

Further, the support member 16 fixed to the lower part of the binding device 7 has a pair of upper and lower rollers 17, respectively.
The rollers 17 roll while being guided by rails 19 supported by supports 18 erected on the machine base 2, and thereby the binding device 7 adjusts its movement in the direction of the culm of the waste straw. The connecting rod 20 of the upper part is screwed into the elongated hole of the upper support frame 21 with a tightening bolt 22.

An elastic plate 24 made of rubber or synthetic resin is provided on the outlet plate 23 protruding from the lower edge of the discharge culm 6.
The pipes 2 are arranged in a row so as to protrude above the guide plate 15 and are fixed to the ear side of the binding device 7.
5 and 25, the end of a rod-shaped cap 27 of a collection bag 26 is loosely fitted into the end of the rod-shaped cap 27 of a collection bag 26, and the collection bag 26 is shown in FIG. As shown, the l
It is placed so that it sticks out.

In the drawing, 28 is a grain scattering prevention sheet suspended from the culm opening 6, and 30 is a collection bag 2 from the belt cover 31.
A rubber plate 32 is a grain-lifting cylinder suspended into the container 6.

In the above-mentioned mobile threshing machine, the straw discharged from the culm discharge port 6 of the threshing device 1 is supported and guided by the elastic plate 24 at the lower part, and guided by the elastic guide 33 at the upper part, while passing through the raking wheel which interlocks with the handling barrel shaft. 34 and scraping arm 35
The culm is scraped toward the collection culm 8, and the packer 11 scrapes it into the front of the door 13 and collects it.

At that time, while the waste straw discharged from the waste culm port 6 moves onto the guide plate 15, the grains separated from the elastic plate 24
The grains are caught by the threshing device 1 and the binding device 7 and flow into the machine from the culm opening 6 without falling, and are discharged during the raking operation of the raking arm 35 etc. and during the raking operation of the husking car 11. The grains separated from the straw flow down the guide plate 15 toward the panicle side, and the grains in the collecting culm part 8 also fall into the collection bag 26 from the gutter-like parts 15a and 15b, and are scattered from the panicle side of the culm discharge port 6. Alternatively, the separated grains flow down on the rubber plate 30 and enter the collection bag 26.

Furthermore, when the bundling device 7 is moved to the panicle side and set, the collection bag 26 protrudes further from the panicle side end of the culm outlet 6 as shown by the dotted line in FIG. 1, so that the grains are scattered outside. Even when the bundling device 7 is moved to the farthest position and set, the collection bag 26
As shown by the solid line, protrudes from the ear side end of the culm opening 6 by l towards the panicle side and faces the exhaust culm opening 6, so that scattered grains and detached stab grains can be reliably collected. .

When the straw collected in the collection culm 8 reaches a predetermined amount and the one-turn clutch is engaged, the needle 12 and the knotting part 9 are activated to knot, and the discharge arm 10 discharges the bundle while removing the knots.

(g) Effects of the invention Since the invention is constructed as described above, the grains that are about to fall from between the threshing machine and the binding device 7 can be caught by the elastic plate 24, and the grains can be ejected on the guide plate 15. The grains separated from the straw can be reliably collected from the guide plate 15 into the collection container disposed on the ear side.

In addition, when the bundling device 7 is moved toward the culm of the waste straw in order to change the bundling position for the waste straw discharged from the discharge culm port 6, the collection container attached to the bundling device 7 moves integrally. Therefore, the positional relationship between the collection container and the ear side end of the guide plate 15 does not change, and regardless of the bundling position, grains falling from the guide plate 15 can be accurately collected without leaking into the collection container. be able to.

Furthermore, when attaching and removing the collection container, not only when the tying device is set on the stock side, but also when adjusting the movement toward the ear side, the collection container is moved toward the ear side together with the tying device, and the guide plate becomes an obstacle. The combination of the fact that it does not cause any damage and the fact that it can be configured compactly allows it to be easily attached and detached.
