Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a culm discharge device for a reaper, particularly suitable for reaping beans.

In order to conveniently collect the harvest after harvesting, the reaper transfers and stores the cut culms to a discharge guide box attached to the rear of the reaper, and discharges a certain amount onto the field intermittently.

In this case, if the outlet of the guide box is high relative to the ground, an opening/closing door can be provided at the bottom of the box to allow the culm to be discharged and dropped in a hopper style, but if the outlet is low, an opening/closing door should be provided at the bottom of the box. I can't.

The object of the present invention is to provide a shell culm discharge device suitable for cases where the discharge port is low relative to the ground and the shell culm cannot be discharged and dropped in a hopper style as described above.

The embodiments shown in the drawings will be described below.

1 is a reaper, and 2 is a culm discharge guide box with an open top surface attached to the rear of the reaper 1 by screws, welding, or other suitable means, and a culm delivery port 3 that has been cut is placed on the mounting side of the box. It has a culm outlet 4.

Reference numeral 5 denotes a known culm conveyor for transporting the cut culm to the discharge guide box 2, 6 a portal-shaped bearing frame provided astride the box 2, and 7
a, 7b are bearings provided oppositely on both sides of the rear of box 2; 8a;
t 8b, 9a, 9b, 10at 10b is the bearing frame 6,
Shaft 1 is placed at each vertex of the triangle on bearings 7a and yb.
These are the sprockets attached at 1, 12, and 13.

In this case, the axes 11 and 12 are left and right independent axes, but the axis 13
The bearing 7a has one shaft.

A sprocket 10a is provided at both ends of the Tb.

10b is attached.

14a? 14b are sprockets 8a, 9a, 10a, 8b, 9b.

A chain serving as an endless conveyor is suspended from 10b, and one side of the triangle is parallel to the top surface of the box 2.

A belt may be used instead of a chain. 15 is a sprocket attached to the shaft 11, and a chain 16 is suspended from this sprocket.
Power is obtained from the reaper 1 side via the reaper 1 side.

Reference numeral 17 denotes a culm scraping member; 18 denotes a guide wall for lowering the scraping member, which is erected on the upper surface of the box 2 in parallel with the bearing frame 6; and 19 denotes an opening/closing door attached to the outlet 4 of the box 2 with a hinge 20. It is always urged in the closing direction by the spring 21.

Reference numeral 22 denotes the corrugated bottom of the box 2, and the concave portion thereof stores grains shed from the culms during transportation.

As shown in FIG. 3, the Q culm scraping member 17 is constructed by arranging a plurality of rods 24 in a fork-like manner on a tube shaft 23, and the rods 24 are placed at the lower part of the tube in order to facilitate scraping. is bent forward into an L-shape as shown in the second figure.

A shaft 25 is inserted into the tube shaft 23, and the small diameter threaded portions 26 at both ends of the shaft 25 are connected to the chain 14a14 as shown in FIGS.
It is passed through the hole 29 of the ear piece 28 provided on the outer pin ring 2T of b, and the nut 30 is screwed in to secure it.

When you hold the steering bundle 31 and move the reaper 1 forward,
A catching rod 3 provided at the front of the reaper 1 so as to protrude forward
The culms of the ridges that were tilted or fallen due to step 2 are aligned, and the bases of the culms are cut with a cutter 33.

The cut culm is conveyed by the conveyor 5 toward the discharge guide box 2, and while being conveyed, it is naturally tilted in a fixed direction and is carried into the guide box 2 through the carry-in port 3.

At this time, since the chino 14a is driven via 16-15-11 and the chino 14b is driven via 14a-13, the scraping member 17 is guided by the descending entry guide wall 18 and enters the box 2 from the open top part. , moves toward the discharge port 4.

At this time, the lower surface of the L-shaped guide 34 provided on the tube shaft 23 contacts the upper edge 2□ of the box 2, so the bar 24 maintains a substantially vertical state within the box 2, and the culm 35 inside the box is expelled. It is moved toward the exit 4, and the door 19 is opened against the spring 21 by the pushing force of the movement, and the door 19 is discharged and dropped.

Similarly, the scraping member 1 entered the box at certain time intervals.
7, that is, it is discharged using a bar 24.

Note that the scraping member 17 moves while suspended from the chinos 14a and 14b, but when passing around the shaft 130, it touches the shaft 13 and touches the chino 14a.

14b.

Since the present invention has the above-mentioned configuration, the discharge port of the culm discharge guide box can be provided at any height position relative to the ground.

Therefore, it can be applied without any inconvenience even when the discharge port must be provided near the ground.

Further, when the scraping member suspended from the chain performs the scraping operation, the engagement between the guide member and the upper edge of the assembly prevents the guide member from swinging, so that the scraping operation can be carried out reliably.

In the figure, reference numeral 36 denotes an arcuate cutout portion provided at the rear upper edge of the box 2 so that the rotation of the guide 34 is not hindered.
