Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention provides a method for collecting cut and tied stem culm bundles in a certain amount R.
The present invention relates to a stem culm bundle collection device that can be left in place.

[Conventional technology]

Such a stem culm bundle collecting device includes a single clamping and transporting device that lifts and transports the cut and tied bundles of stalks and culms in a sideways position and transports them backwards and upwards, and a clamping and transporting device that lifts and transports the stalk and culm bundles that have been dropped and released from this clamping and transporting device and flips them sideways. The device is equipped with a collecting section for placing the bundle in a posture, and a receiving section is provided behind the terminal end of the clamping and conveying device to temporarily catch the released stem culm bundle in a sideways posture and then drop and release it to the collecting section. This method was previously proposed by the present applicant (Utility Application No. 1983-032125).

The holding and conveying device (C) of this stem and culm bundle collection device will be described in detail.As shown in FIG. ) A driving sprocket (17) at the lower end and a driven sprocket (18) at the upper end pivotally supported in
The chain with protrusions (19) is wound around it, and
A clamping rail (20) is provided along the protruded chain (19) exposed to the front side from the chain case (16).

Further, the receiving portion (E) includes a receiving plate (24) which is movable up and down around the left and right horizontal axis above the terminal end of the clamping and conveying device (C).
It is possible to switch between a position in which the bundle of stems and culms dropped and discharged from the clamping and conveying device (C) is received in a sideways position and a position in which the received bundle of stalks and culms is dropped and released into the recovery section, and a receiving position is A spring (
34) and a locking device is provided to lock it in the receiving position.

And a release operation tool (28) for releasing this locking device.
is installed in the path (R) of the clamping and conveying device (C), and is configured to be released by contact with the stem and culm bundle being conveyed (see FIG. 8).

[Problem that the invention seeks to solve]

In the stem culm bundle collecting device configured in this way, when the locking device is released and the receiving plate (24) becomes vertically swingable, it swings upward under the weight of the stem culm bundle and switches to the release position, and the stem culm bundle is released. The culm bundle falls and is discharged to the collecting section. After that, the receiving plate (24)
is swung upward by the elastic restoring force of the spring (34) and automatically returns to the original receiving posture. However, the receiving plate (24
) tries to return to the receiving position not after the stem culm bundle has completely fallen and is released, but when the load applied to the receiving plate (24) decreases as the stem culm bundle begins to fall, and This starts when the elastic restoring forces of the spring are balanced.

Therefore, from that point on, even though some of the stem culm bundles still remain on the receiving plate (24), the receiving plate (24)
automatic recovery begins. The automatic return at this time is one of the causes of disturbing the release posture of the stem culm bundle.

In view of these circumstances, the present invention aims to improve the disturbance in the ejection posture caused by the automatic return of the receiving plate (24).

[Means for solving problems]

The characteristic configuration of the present invention includes a single clamping and transporting device that lifts and transports the bundled stem and culm bundles in a sideways position, and a clamping and transporting device that carries the bundle of stems and culms dropped from this clamping and transporting device in a sideways position. A collecting section is provided at the rear of the terminal end of the clamping and conveying device, and is freely swung between a receiving position in which the released stem culm bundle is received in a sideways position and a discharging position in which the received stem culm bundle is released to the collecting part. A locking device for fixing the receiving member in the receiving posture is provided in a lock biased state, and a release operation tool for releasing the locking device is temporarily installed in the path of the clamping and conveying device. and is configured to be released by contact with the conveyed stem culm bundle, and
A return operating tool is disposed on the downstream side of the release operating tool to return the receiving member in the releasing position to the receiving position by contact with the transported stem culm bundle. The effects are as follows.

[For production]

That is, the bundled stem and culm bundles are lifted and transported backward and upward by the clamping and transporting device, and are dropped and discharged from the terminal end thereof. The fallen and released stem culm bundle is once received in a horizontal position on a receiving member fixed in a receiving position. Then,
When the subsequent stem culm bundle in the path of the clamping and conveying device comes into contact with the release operating tool installed in the path, the locking device that fixes the receiving member is released, allowing the receiving member to swing freely. It becomes a state. Then, the receiving member is swung upward by the weight of the stem and culm bundle to assume the releasing position, and the stem and culm bundle is dropped and released onto the collection unit while remaining in the sideways position. At this point, the receiving plate remains in the release position. Next, when the subsequent stem culm bundle comes into contact with a return operation tool installed on the downstream side of the release operation tool, the receiving member is operated to return to the receiving position, and the locking device is again activated to lock. become a state.

〔Effect of the invention〕

Therefore, the receiving member does not return to the receiving posture until the stem culm bundle is completely dropped and released from the receiving member, and the releasing posture of the stem culm bundle is disturbed by the upward swinging of the receiving member. It's gone.

In addition, it has become possible to orderly place the stem and culm bundles that have fallen on their sides on the recovery unit.

Next, the operation of the receiving portion (E) will be specifically explained based on the above configuration.

In a state where the shell culm bundle is received on the receiving plate (24) fixed in a horizontal position, the subsequent shell culm bundle is moved to the first contact link ( 28), the L-shaped link (25) rotates in conjunction with the swinging of the top of the first contact link (28), and the contact pin (25a) and the arcuate link (27) come into contact with each other. In other words, the locking device (29) is released and the receiving plate (24) becomes vertically swingable. Then, due to the weight of the culm bundle, it swings upward against the receiving plate (24) and assumes the release position.
The shell culm bundle is dropped and released onto the recovery section (D) in a sideways posture (see Fig. 4). Immediately after this, L-shaped link (25)
The first contact link (28) is pushed back to the initial state by the spring (30), but the receiving plate (24) remains in the released position. Next, when the subsequent culm bundle in the path (R) contacts the second contact link (32), the small rod (33
) is pushed downward and the arc-shaped link (27)
swings upward. Then, as the arc-shaped link (27) swings upward, the receiving plate (24) swings upward and returns to the receiving position, and at the same time, the contact pin (25a) and the arc-shaped link (27) come into contact. In this state, the receiving plate (24) is in a fixed state.

The recovery section (D) is configured to be able to dump around the shaft center (P3) at the rear end so that the loaded bundles of shell culms in a sideways posture can be lowered to the ground all at once.
