Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a discharge switching device for a second thrower in a threshing machine.

In other words, from the No. 2 conveyor side to the handling room or processing room, 2
Unprocessed material can be discharged from the middle of the thrower tube in the second thrower for cleaning after work, and when threshing for seed harvesting, the second thrower can damage the grains. It is possible to take out the air in a good manner without clogging or to take out the air in a good manner without clogging, or to take out wind power for cleaning the aircraft body, and it is provided so that it can be carried out suitably.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a cross-sectional view of a threshing machine mounted on a conveyor.
1 is a handling room, 5 is a handling barrel, 6 is a supply port, 7 is a crimp net, 8 is a swinging sorter, 9 is a dust outlet, 10 is a winnowing machine, 11 is a No. 1 conveyor, and has the same structure as the conventional type. It is.

A No. 2 conveyor 1 is installed inside the No. 2 gutter 12 installed horizontally below the stroke rack 8a of the swinging sorter 8, and the No. 2 thrower A installed on the side of the machine jumps. The terminal side of the No. 2 conveyor 1 is communicated with the inside of the trunk 13, and a jump wheel 14 coaxial with the No. 2 conveyor 1 is installed inside the jump trunk 13. The tip opening 15 of the No. 2 thrower cylinder a to be taken out is connected to the handling chamber 2, and the structure is similar to the conventional type.

An opening 3 is formed in a portion of the back surface 16 in the middle of the second thrower cylinder a, and support pieces 17 and 17 are protruded from both sides of the end of the opening 3 on the side of the tip opening 15. Piece 17
．． One outer end of a support shaft 18 rotatably mounted on the support shaft 17 is bent in the orthogonal direction to form a grip rod 18a, and both support pieces 17.
One end side of a flat plate switching valve 4 is fixed to the support shaft 18 between the openings 17 and 17, and when the switching valve 4 is aligned with the opening 3, the tip engages with the support protrusion 19 at the end of the opening 3. Switching valve 4
When the switch valve 4 is rotated toward the ventral surface 20 side of the second thrower cylinder a, the switching valve 4 is installed in an inclined state within the cylinder and its tip joins to the ventral surface 20 side, but the tip of the switching valve 4 is supported. It is installed and configured so that it can be joined to the protrusion 19 and stopped in a state where the opening 3 is closed.

In addition, screw holes 21, 21 are formed in both side surfaces of the No. 2 thrower cylinder a on both sides of the opening 3, and the tip 2
The base of the curved discharge tube B having the opening No. 2 is formed so that it can match the opening 3, and both support plates 23 and 23 extending from both sides of the base can be joined to both sides of the No. 2 thrower tube a. The screws 24 and 24 that pass through both support plates 23 and 23 are screwed into the screw holes 21 and 21, so that the discharge tube B can be detachably connected.

In the figure, 25 is a grain bag, and 26 is a flexible blowing pipe whose one end can be connected to the distal end 22 of the discharge pipe B via a band 27.

During the threshing operation, if the switching valve 4 is connected to the opening 3 as shown in FIGS. The objects are jumped up by the jump wheel 14 and flow along with the wind inside the second thrower tube a as shown by arrow A, and are returned to the treatment chamber 2 for processing.

After the work or as needed, grip the gripping rod 18a and rotate the switching valve 4 so that the tip of the switching valve 4 joins the ventral surface 20 of the No. 2 thrower cylinder a and tilts as shown in FIG. When the operation is performed so that the unprocessed material after the work is carried out along with the wind,
The unprocessed material can be guided by the flow through the opening 3, and the unprocessed material can be discharged to the outside for cleaning.

In addition, when performing threshing work for seed collection, selector valve 4
As shown in FIG.
．． 23 is fixed with screws 24 and 24 and assembled as shown in FIG.
It is possible to prevent the grain from being damaged by returning the second grain to the handling room 2. Also, during seed harvesting, each rotating part is set at low speed to prevent unweighed rice from coming out. Therefore, even if the No. 2 thrower A rotates at a low speed and the lifting force decreases, the opening 3 in the middle can be taken out, and clogging in the No. 2 thrower A can be prevented.

Furthermore, if a flexible blower pipe 26 is similarly connected to the tip of the discharge tube B as shown in FIG.
The air generated by A is discharged from the air pipe 26, and straw waste and rice grains inside and outside the machine body can be removed by pressure air to perform cleaning.

In this way, the present invention forms an opening 3 that communicates with the outside in the middle of the thrower cylinder 2 in the No. 2 thrower that carries out the No. 2 return from the No. 2 conveyor 1 side to the handling chamber 2 or processing chamber. A communication direction switching means 4 is provided in the opening 3, and a discharge pipe B or a blower pipe 26 can be connected in a detachable manner.
Because we made it possible to take out grain or wind outside,
By switching the switching valve and opening the opening, unprocessed material can be discharged from the middle of the No. 2 thrower cylinder after work or as needed for better cleaning.When collecting seeds with a threshing machine, It is possible to take out the second grain from the middle of the second thrower tube without damaging the grain by returning it to the handling room etc. as in the conventional method. The second object can be taken out to prevent it from clogging the No. 2 thrower, or the wind power can be taken out from the opening of the No. 2 thrower cylinder and used for cleaning. The present invention has the advantage that it has a simple structure and can be suitably implemented.
