Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a stem culm bundle recovery device capable of binding conveyed stem culms and placing a fixed amount of the stem culm bundles. Regarding

[Conventional technology]

As a stem culm bundle recovery device of this type, as disclosed in Japanese Patent Laid-Open No. 51-124527, a raising device that causes planting stalk culm at the front of the fuselage, and a stalk culm bundle that has been cut A cutting device and a bundling device for bundling the cut culm bundles in a vertical position, and at the rear of them, hold the stalks in a horizontal position and lift the stalks in a horizontal position to discharge them in a horizontal position and release them while holding them. A device provided with a device is known.

Also, in this stem culm bundle collecting device, the cut stalks are bundled in the vertical posture by the tying device, the stem culm bundle is laid down sideways and converted to the posture, and then the scraping conveyer at the lower end of the grasping conveyer device holds and conveys it. It is designed to supply to the stem culm bundle supply port of the device.

[Problems to be solved by the invention]

The stem culm bundle recovery device described above is capable of supplying the bundled stalk culm bundle to the stem culm bundle supply port for a while, but the posture collapses when the stem culm bundle is changed from the vertical position to the horizontal position. There is a possibility that the carrying posture of the holding and transporting device and the discharging posture are easily disturbed, so that the postures of the stem culm bundles on the collecting part are not aligned and are easily collapsed, or the loadable capacity is reduced. Further, it is necessary to provide a scraping rotator for scraping the stem culm bundle into the stem culm supply port, which causes a problem that the structure becomes complicated.

In consideration of such circumstances, the present invention simplifies the structure and, at the same time, aligns the conveying posture and the discharging posture of the stem culm bundle so that the stem culm bundle can be stably placed on the collecting part and has a specified amount. The purpose is to be able to fully load.

[Means for solving problems]

In order to achieve the above-mentioned object, the stem culm bundle collecting device according to the present invention bundles the conveyed stem culms and discharges them in a sideways posture, and holds the discharged stem culm bundle in a sideways posture. While holding a carrying device for lifting and carrying, and a recovery unit for placing a stem culm bundle discharged from the end of the holding and conveying device, the discharging device of the binding device for discharging a stalk culm is a stem. The present invention is characterized in that it is configured such that the stem culm supply port is closed in a stopped state immediately after discharging the culm bundle to the stem culm supply port of the holding and conveying device.

The operation and effect of this characteristic configuration are as follows.

[Action]

In other words, the conveyed stem culms are bundled by the tying device by a predetermined amount and then immediately discharged to the stalk culm supply port in a sideways posture by the discharging device of the tying device. At that time, when the discharging tool blocks the stem culm supply port for a predetermined time in the stopped state immediately after that, the discharged stem culm bundle does not bite well or hits an unintended place and repels to escape from the stem culm bundle supply port. This prevents the bundle of stems from being caught and is reliably held by the holding and conveying device. Then, the stalk bundle is lifted and conveyed while being held in a horizontal posture by the holding and conveying device, and discharged from the terminal end in the horizontal posture to the collecting section.

[Effect of device]

As a result, no special scraping rotor is required, and the structure is simplified. In addition, since the bundle of bundled stalks is laid down sideways and immediately supplied to the stalks supply port in a posture, the posture is not collapsed, and the conveyance posture in the holding and conveying device, and further the disturbance of the discharge posture is improved, and the stem culm bundle is improved. It is now possible to load up to the specified amount in a stable state on the collection part.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 5 and 6, a cutting pretreatment unit of the same type as the combine is provided on the front of the combine-based traveling machine body.

Further to the rear and to the left of the control section (1), a holding and conveying device (C)
Further, the collecting unit (D) is mounted on the rear side of the collecting unit (D) to form a cutting and binding machine with a collecting device, which is an example of a stalk-and-bundle collecting device.

The cutting pretreatment unit (A) is a raising device (2) that causes planted grain culms, which is a type of stem culm, a pair of packers (3), (3) that scrapes the caused grain culm into the center, A mowing device (4) for mowing the collected grain stalks, and a vertical transport device for transporting the harvested grain stalks backwards and upwards while gradually lying down.
It is composed of (5) etc. The vertical transporting device (5) is a tip locking transporting device that locks and transports the tips of the grain culms (5A), and a strainer holding and transporting device that grips and transports the roots (5B). Then, the grain culm in a vertical position is laid down in a horizontal position and conveyed upward,
The stock source is sent to the belt with protrusions (6) and (6) for lifting the stock source arranged at the left end of the aircraft. In addition, the stock yuan payment rod (7) for smooth feeding of the stock origin is a belt with a protrusion from the machine body.
It is provided over the starting end side of (6) and (6).

As shown in FIG. 1 and FIG. 2, the belts with protrusions (6) and (6) are arranged side by side in a pair, and the plant center of the grain culm sent to the lower side is placed on the lower side. Carry on the route part and carry it upward and backward. At the end of the conveyance path of the protrusion belts (6) and (6) and before the grass-collecting space of the binding device (B), in other words, the action of the tip trajectory of the packer arm (8) of the binding device (B). A cutting device (9) for cutting the root ends of the grain culms is provided near the terminal end. As shown in FIG. 3, this cutting device (9) forms a long hole (10a) in a long piece portion of an L-shaped link (10) which is rotatable around an axis (P ₁ ). While inserting the pin (11a) at the tip of the crank arm (11) into the long hole (10a),
An engaging portion (10b) is cut out at the tip of the short piece portion, and a pin (12a) of a movable blade (12) is engaged with the engaging portion (10b). According to this structure, when the crank arm (11) rotates, the link (10) swings in conjunction with it, and the movable blade (12) engaged with the short piece slides with respect to the fixed blade (13). The cutting action works.

Belts with protrusions (6), a binding device (B) is arranged at the rear end of the ends of the belts (6), and when the grain culms in the sideways-inclined posture are scraped by the packer arm (8) to be bundled. At the same time, they are bundled and the grain culm bundle is discharged rearward by using a discharge door (14) as an example of a discharge tool. Incidentally, the belt with protrusions (6), (6)
A part of the trailing end portion and the trail of the tip of the packer arm (8) are overlapped in a side view so that the grain culms can be delivered and received smoothly. The discharge door (14) is a blade-shaped member that rotates around the left and right horizontal axis (P ₂ ), and its working portion faces the grain culm supply port (15) of the holding and conveying device (C). There is. The discharge door (14) is always driven to rotate when the binding device (B) is operated, but immediately after the discharge of the grain culm bundle, it is temporarily stopped before the grain culm supply port (15). The supply port (15) is closed so that the supplied grain culm bundle can be reliably delivered to the holding and conveying device (C). In other words, since the holding and conveying device (C) is a holding and conveying method and is directed upward, the supplied grain culm bounces off at an involuntary place, or if it bites poorly, it is delivered. There is a risk of failure and falling down from the grain culm supply port (15). Therefore, after the grain culm bundle is discharged, the discharge door (14) closes the grain culm supply port (15) for a certain period of time to assist in reliably holding the grain culm bundle.

As shown in FIG. 3, the holding and conveying device (C) is provided with a chain case (16) in a posture in which the chain case (16) is high upward and slightly inclined rearward, and the lower end of the chain which is pivotally supported in the chain case (16) is driven. The chain with protrusions (19) is wound around the sprocket (17) and the driven sprocket (18) at the upper end, and is also clamped along the protrusion chain (19) exposed to the front side from the chain case (16). It is constructed by providing rails (20). Also, the shaft (21) of the driven sprocket (18) is extended to the outside of the chain case (16), and a rotating tool (22) for picking up and removing grain culm is attached to the tip end side of the chain (16). A large-diameter rotary shaft (23), which is driven to rotate integrally with the shaft (21), is fitted therein.
Further, at the rear of the upper end of the holding and conveying device (C), in other words, at the rear of the end, the grain culm bundles discharged from the device (C) are temporarily laid down and temporarily received, and then the collection unit (D) is discharged at once. A stop (E) is provided.

Therefore, the grain culm bundle supplied to the grain culm supply port (15) is conveyed upward and rearward in a sideways posture while being held by the chain with protrusions (19) and the holding rail (20), and when reaching the end thereof, the rotating tool (22) and the rotary shaft (23) are crossed over, and once the receiving portion (E) is reached.
After falling to the side and laying down sideways, it is dropped and released to the lower collecting section (D). Incidentally, the rotating tool (22), the grain culm is arranged to release the grain culm bundle by scraping up the hanging tips when the bundle reaches the end of the holding and conveying device (C), and the receiving portion (E) This is to prevent the falling posture of the grain culm from falling sideways. Also, when several grain culms separated from the grain culm bundle remain in the transport route when the grain culm bundle falls to the receiving part (E) and is caught in the succeeding grain culm bundle, the grain culm bundle is received. Stop (E)
It may cause a large disturbance in the release posture when the product is released from the ground. Therefore, by providing the rotating shaft (23) on the stock side, the grain culms that were scattered when the grain culm bundles dropped and released to the receiving part (E) were hooked on the rotating shaft (23), and through friction. Rotating shaft (2
The rotation force of 3), the weight of the rice culm bundle and the elastic restoring force pull it upward to help it get out of the transport route, and prevent it from being caught in the succeeding wheat culm bundle.

The receiving portion (E) is provided with a receiving plate (24) which is swingable up and down about the left and right horizontal axis at the rear end of the holding and conveying device (C), and the receiving plate (24) is placed in a horizontal posture. A state in which it is possible to receive the grain culm bundle that has been locked and dropped from the holding and conveying device (C), and a state in which the lock can be released and the receiving plate (24) can swing up and down, in other words, the grain culm bundle. The receiving plate (24) swings downward due to its weight and is automatically switched to a state in which the grain culm bundles can be dropped and discharged. More specifically, L is attached to the side wall of the holding and conveying device (C).
The character-shaped link (25) is rotatably pivotally attached, and the rod (26) is pivotally connected to the tip of one of the pieces, and the pin (25a) is formed at the tip of the other piece to form the catch plate (24). It is brought into contact with the tip end portion of the arcuate link (27) which swings integrally with. Further, the contact link (28) is provided on the side wall located below the L-shaped link (25).
Is pivoted so that it can be swung up and down, and its tip is held by a carrier device (C).
Of the rod (26), and the lower end of the rod (26) is pivotally connected, so that the L-shaped link (25) is rotated in conjunction with the swinging up of the contact link (28). The contact between the hit pin (25a) and the arcuate link (27) is released, that is, the lock of the receiving plate (24) is released. In short, in the state where the grain culm bundle is received on the receiving plate (24),
When the succeeding grain culm bundle comes into contact with the contact link (28) on the lifting and conveying path and swings upward, the lock of the receiving plate (24) is released and the grain culm bundle on it is retained by its own weight. It slips off from 24) (see Fig. 4). After the drop of grain culms is released, the L-shaped link (25) and the contact link (28) are returned to the initial state by the spring (29), and the catch plate (24) is also moved by the spring (30). It is returned to the horizontal position and returns to the original locked state.

The collecting section (D) is configured to be capable of dumping around the rear end axis (P ₃ ) so that the stacked grain culm bundles in the sideways posture can be collectively lowered onto the ground. Moreover, when the collecting section (D) dumps, the rear side plate (31) falls and becomes flush with the bottom plate (32), so that the grain culm bundle can be smoothly slid to the ground.

The present invention may be applied to a stem-culd bundle collecting device that scrapes up and collects grain culms that have been left lying sideways in a field. Further, as a release tool of the binding device (B), a revolving release door (14)
Alternatively, an extruding arm may be used.
