Description

[Detailed description of the invention] (Industrial use!l!?) The present invention relates to a grain guide device for a threshing machine.

(Prior art) In conventional threshing equipment, a wind-selecting room was formed at the bottom of a threshing room equipped with an automatic shell culm feeding device, and the wind-selected second grain was returned to the threshing room with a thrower for processing. .

(Problems to be Solved by the Invention) In the above-mentioned apparatus, there are defects in which grains in the threshing chamber rotate together with the rotation of the handling drum and get stuck in the supply husk bundle, and defects in the second thrower.
There was a defect in the area near the outlet where the discharge was obstructed and clogged.

In other words, a bundle of shell culms is fed into the threshing chamber with the root portion held between them by a shell culm supply device, but the grains that rotate together as shown by arrow A due to the rotation of the handling teeth of the handling barrel are fed into the threshing chamber. It pierces the eastward direction of the culm, like a dotted line. Of course.

The pierced kernels are quickly removed by the rotation of the handling teeth, but the pierced kernels near the culm-shaped outlet are difficult to remove and are removed along with the grain bundle.

In addition, grains rotating at a rapid speed as indicated by arrow A have a significant adverse effect on the thrower's discharge action.

(Means for Solving the Problem) The present invention solves this problem, and the first invention is such that a guide plate is installed in the threshing chamber to move the grains co-rotating near the extraction port to the supply side. The second invention is such that the discharge port of the thrower is formed to protrude somewhat into the threshing chamber to change the moving direction of the co-rotating grains as indicated by the arrow A. It is.

The present invention provides a grain guide device for a threshing machine that is provided with a guide plate for moving the grains co-rotating near the take-out port to the supply side in the threshing chamber, and a second thrower discharge port that protrudes into the threshing chamber. The gist of the present invention is a grain guide device for a threshing device, which is attached to a threshing device and configured to change the direction of co-rotating grains by colliding with the protrusion.

An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a threshing section, and a threshing chamber 2 is provided within the threshing section 1. The inside of the threshing room 2 is handled so that the axial direction is the culm supply direction! 3 will be provided. 4 is a handling tooth of the handling barrel 3, 5 is a handling net below the handling IIP 3, 6 is a winnowing room below the handling net 5, 7 is a feeding rack for sending the grains that have fallen from the handling net 5, 8 is a sieve screen provided at the side end of the feeding rack 7. A first article receiving gutter 9 is provided below the sieve screen 8, and a first pick-up conveyor 710t is provided within the flavored material receiving gutter 9. - A second product receiving gutter 11 is provided on the side of the fragrance receiving gutter 9, and a second product transfer conveyor 12 is provided in the second product receiving gutter 11. 1
3 is a thrower for returning the second grain transferred from the second grain transfer conveyor 12 into the threshing room 2 for reprocessing; 14 is a processing cylinder arranged in parallel to the side of the handling cylinder 3; 15 is a husk. feeding device,
16 is a feeding chute of the culm feeding device 15; 17 is a pinching rod;
18 is a suction chamber, and 19 is a suction blower that sucks the inside of the suction chamber 18 and the selection chamber 6.

As a result, the rotation of the handling drum 3 in the threshing room 2 increases 91. A guide plate 21 is provided above the side 20. The guide plate 21 is formed to be inclined so as to approach the supply port as it reaches the -1-h end in the vertical direction, and as it approaches the culm discharge side 22 when viewed from above as shown in the fSz diagram. Form at an angle so that they are close together.

The guide plate 21 is for returning the grains rotated by the rotation of the handle Irl3 on the husk discharge side 22 of the threshing chamber 2 to the supply port side in the threshing chamber 2.

(Embodiment) In the second embodiment shown in FIGS. 4 and 5, when the discharge port 23 at the upper end of the thrower 13 is opened to the culm supply side 24 in the threshing chamber 2, it protrudes somewhat. This is what I did. As shown in FIG. 5, the handling teeth 4 of the handling cylinder 3 on the shell culm supply side 24 are formed short.

The discharge port 23 of the thrower 13 is formed in this portion. The lower plate 25 forming the discharge port 23 is handled as #15 on the rotation rising side 20.
It is formed so that its tip 27 protrudes from the upper edge 26 of the handle 11; 13 by a width within a range that does not contact the handle teeth 4 of the handle cylinder 3.

(effect) Next, we will discuss the effect.

Culm 2 cut by the cutting part formed on the front side of the combine harvester
B is sent to the shell culm supply device 15 by the feeding device, and the shell culm supply device 15 supplies the shell culm supply side 2 in the threshing chamber 2 of the threshing section l.
The grain is supplied from the shell culm discharge side 22 and threshed by the rotation of the handling drum 3 in the threshing chamber 2. Threshed grains, etc. fall from the handling #15 and enter the wind sorting chamber 6, light dust, etc. are discharged outside the machine by the suction blower 19, and relatively heavy grains, etc. fall onto the feeding rack 7. The first product is transported to the top of the sieve @8 by the swinging of the feeding shelf 7, and the first product is sieved by the sieve net 8 and falls onto the first product receiving gutter 9, and is transferred to the first take-out conveyor 1.
0, the second item falls onto the second item receiving gutter 11, is transferred by the second item transfer conveyor 12, and is transferred to the thrower.
13, the grains are returned to the threshing chamber 2 and reprocessed.

However, it is handled in threshing room 2! Since the r13 is rotating at high speed, the grains shucked from the husk culm 28 rotate together with the handling cylinder 3 as shown by arrow A, and the husk culm 28 is supplied with momentum by the husk culm feeding device 15 later. These small grains, which often fall and become stuck in the east direction of the culm 2B, are taken out on the culm supply side 24 side in the threshing room 2 by the rotation of the handle 1r13, but on the culm discharge side 22, The shell culm 28 will be ejected out of the machine as it is.

However, in the present invention, the culm discharge side 2 in the threshing chamber 2
A guide plate 21 is provided above the threshing room 2, and the guide plate 21, when viewed from above, shows the handling 1r as it reaches the culm discharge side 22 of the threshing room 2.
13, the grains that rotate together due to the rotation of the handling IR 3 collide with the guide plate 21 and return to the middle of the culm supply side 24 and the husk discharge side 22 of the threshing chamber 2. This prevents them from falling onto the shell culm 28 that approaches the shell culm discharge side 22, thus preventing the generation of small grains and preventing them from being discharged out of the machine together with the shell culm 28. .

In the embodiment, the grains co-rotated in the threshing chamber 2 by the rotation of the handling IN 3 are transported by the tip 27 of the lower plate 25 forming the discharge port 23 of the thrower 13 of the handling net 5 on the rotation rising side 20. '' Since it is formed to protrude into the threshing chamber 2 by a width t from the two end edges 26, it may collide with the lower surface of the lower plate 25 and fall downward, or the tip 27 of the lower plate 25 and the handling cylinder 3 may passing through the
The second grain to be returned to the threshing chamber 2 by the thrower 13 smoothly flows into the threshing chamber 2 through the discharge port 23 and is reprocessed. The lower surface of the lower plate 25 also acts as a guide plate, and since the grains that have rotated together with the handling cylinder 3 are returned downward, it also has the effect of preventing the generation of small grains.

(Effects) As already mentioned, conventional threshing equipment has a wind-selecting chamber formed in the lower part of the threshing chamber that has an automatic grain rod feeding device, and the wind-selected second grain is returned to the threshing chamber with a thrower for processing. I was trying to do that. However, the above-mentioned device has a drawback in that the grains in the threshing chamber rotate together with the rotation of the handling drum and become stuck in the supplied shell culm bundle.

There was a defect near the exit of the second thrower where the discharge was obstructed and clogged.

However, the present invention provides a grain guide device of a threshing machine that is provided with a guide plate for moving the grains co-rotating near the take-out port in the threshing chamber to the supply side, and a second thrower discharge port that is installed in the threshing chamber. Since the gist is a grain guide device of a threshing device that is installed so as to protrude and is configured to change the direction of co-rotating grains by colliding with the protrusion, the culm discharge side 22 in the threshing chamber 2 is By means of a guide plate 21 provided above, the grains co-rotated by the rotation of the handling cylinder 3 are made to collide with the guide plate 21 and returned to the culm supply side 24 of the threshing chamber 2, thereby preventing the generation of small grains. In addition, the lower plate 2 forming the discharge port 23 of the thrower ~13
5 is formed so as to protrude into the threshing chamber 2, so that it may collide with the lower surface of the lower plate 25 and fall downward, or it may fall between the tip 27 of the lower plate 25 and the handling cylinder 3. The second grains that have passed through and are about to be returned into the threshing chamber 2 by the thrower 13 smoothly flow into the threshing chamber 2 through the discharge port 23 and are reprocessed.
