Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a focusing packet for a soybean harvester, and more particularly to an opening/closing mechanism for the bottom plate of the focusing packet.

[Prior art] As a soybean harvester, the stalk culms of soybeans planted in the field are harvested with a harvesting device installed at the front of the machine, and the harvested stalk culms are conveyed using a rubber belt, protruding chain, etc. A device has been developed in which the stem culms are conveyed by a device, concentrated into a focusing packet, and a certain amount of stem culms that have been focused into the focused packet are released into the field, and some of them have been put into practical use.

The work after reaping is generally 3~51r.
In order to dry the soybean bundles released at rIn intervals in the field, it is necessary to perform so-called waste standing, and when doing this work, if the released soybeans are out of position, it takes time to realign them. Since this is undesirable and requires a lot of time and effort, it is strongly desired that the released soybean bundles should be spread out as little as possible, their posture should not be disturbed, and there should be less splitting.

The reasons why the released soybean bundles are spread and disturbed in the field are: firstly, the soybean bundles do not fall from the focusing packet instantaneously and the reaper moves during this time, and secondly, the focusing packet is not fully opened. Since the closing operation begins at the same time, the end of the bottom plate can be used to catch fallen soybean bundles.

Therefore, in order to solve the first cause, it is necessary to simplify the configuration of the focusing packet to minimize the frictional resistance when soybeans fall, and to instantly bring the bottom plate to the maximum open position. In the conventional method, the focusing packet is constructed using left and right side plates and a bottom plate, or these are integrated, and these are mechanically pushed apart to open, making it possible to fully open the packet instantaneously. I couldn't do it.

Furthermore, currently nothing has been done to solve the second cause.

Furthermore, if the bundled packet is too high, it will fall and cause condensation when released, resulting in loss.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and uses a cam mechanism to instantly fully open the front end of the bottom plate provided in the focusing packet in the direction of movement of the fuselage, and to maintain the fully open position for a predetermined period of time. By closing the soybean bundle, it is possible to drop the soybean bundle instantly, and it can be closed without catching the bottom plate on the soybean bundle, allowing it to be released without disturbing the posture of the soybean bundle. The purpose of the present invention is to provide a focusing packet in a soybean reaper which, by being located close to the soybean reaper, reduces condensation during discharge.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 1 indicates a soybean harvester, and drive wheels 2,
Equipped with auxiliary wheels 3, a pair of left and right dividers 4 at the front of the fuselage,
A cutting blade 5 is provided at the rear lower part of the divider 4, a conveyance starting end is provided above the cutting blade 5, and conveyance belts 6, 6 each consisting of a pair of left and right belts extending obliquely upward at the rear of the machine body are provided.

A delivery belt 7 is provided at the end of the transport of the transport belts 6, 6 toward the side of the machine body, and a focused packet 8 is brought close to the ground below the end of the delivery belt 7.

The focused packet 8, as shown in FIGS. 2 and 3,
A side plate 9 fixed to the body in a forward-slanting manner, a fixed shaft 10 projecting horizontally from the body below the lower end of the side plate 9, and a rotating shaft rotatably supported by the fixed shaft 10. 11 and rotation axis 1
A cam follower 13 is fixed to a rotating shaft 11, and a bottom plate 12 has a front end fixed to the bottom plate 1, and a bottom plate 12 whose other end extends in a substantially horizontal direction toward the rear of the machine on the opposite side of the side plate 9. A cam 14 is provided which comes into sliding contact with the cam follower 13.

The cam 14 has a circular convex portion 14a and a notched concave portion 14b, and closes the bottom plate 12 when the cam follower 13 is in sliding contact with the convex portion 14a, and opens when it is in the concave portion 14b. Further, the recessed portion 14b has a predetermined length with respect to the rotational direction of the cam 14, and the recessed portion 14b has a predetermined length (
(approximately 0.1 seconds) to keep the bottom plate 12 fully open.

The opening/closing operation of the bottom plate 12 can be adjusted as appropriate by changing the size of the cam 14, the rotational speed, the length of the recess 14b, etc.

The focusing packet 8 may have the configuration shown in FIGS. 4 to 7, and is suitable when the yield of soybeans to be harvested is very large.

In this embodiment, a bendable support arm 15 is provided between the lower surface of the bottom plate 12 and the fuselage, and supports the bottom plate 12 in a closed state when extended, and fully opens the bottom plate 12 when bent.
A cam 16 for bending the support arm 15 is provided, and a bottom plate lifting rod 17 is provided in place of the cam follower 13, and engages with this rod 17 to lift the bottom plate 1.
Bottom plate lifting drive disk 18 having a pin 18a for pulling up 2
has been established.

The cam 16 and the bottom plate lifting drive disk 18 rotate at a constant rotational speed, and after the cam 16 and the support arm 15 fully open the bottom plate 12, the rotation speed is about 0.1 to 0. After hoeing, the bottom plate 12 is closed by the bottom plate lifting drive disk 18 and the bottom plate pulling rod 17.

Also in the case of this embodiment, the cam 16 and the bottom plate lifting drive disc 1
By changing the size, rotation speed, etc. of 8, the bottom plate 1
The opening and closing operations of 2 can be adjusted as appropriate.

A soybean harvester having such a configuration runs along rows of soybeans planted in rows in a field to perform harvesting work.

The soybean stem culms cut by the cutting blade 5 are conveyed while being held by a conveying belt 6.6, and are sequentially focused onto a focusing packet 8 from a feeding belt 7.

Then, when the amount of convergence of the stem culm reaches a nearly constant amount, that is,
When the reaper travels a predetermined distance, the cam 14 or 16 rotating at a constant rotational speed during this time causes the cam follower 13 to move into the recess 14b in the embodiments shown in FIGS.
Once inside, the bottom plate 12 is instantly fully opened as shown in Fig. 3, and the soybean stem and culm bundles are dropped onto the field.

Then, the bottom plate 12 maintains the fully open position for about 0.1 seconds while the cam 14 rotates by the length of the recess 14b. During this time, the reaper moves forward and the protrusion 14a of the cam 14 moves the cam follower 13. When pushing up to close the bottom plate 12,
The tip of No. 2 closes the upper part of the stem culm bundle that has fallen onto the field without catching it.

Also, since the bottom plate is close to the ground, fewer soybeans fall into the confectionery.

In the embodiments shown in FIGS. 4 to 7, when the convex portion of the cam 16 comes into contact with the support arm 15, the support arm 15 is bent, and the bottom plate 12 is instantly bent as shown in FIGS. 6 and 7. It is fully opened and the stem culm bundle falls onto the field, and the size is 0.1 to 0.
After the hoe is fully opened, the pin 18a of the bottom plate lifting drive disc 18 contacts the bottom plate lifting rod 17 to close the bottom plate 12, and the support arm 15 is extended, and the tip of the bottom plate 12 is moved to the field as in the previous embodiment. The released stem culm is not caught.

Therefore, the stem culm bundles released into the field are not spread out and are kept together, and their posture is not disturbed, which is convenient because there is no need to rearrange them when performing island-erecting work.

In both of the above embodiments, the bottom plate 12 is opened and closed automatically using a cam or the like, but it goes without saying that this may be done manually.

[Effect of idea]

As explained above, according to the focusing packet in the soybean harvester of the present invention, the focusing packet is provided close to the ground,
The soybean stem culms collected in the focusing packet can be released into the field instantly without falling and spreading, and without being processed into confectionery.Furthermore, the closing operation of the bottom plate does not disturb the stem culm bundle, making it easy to Easily erecting islands, housing work, etc.
Can be done efficiently.
