DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a stem culm bundle collection device capable of storing a certain amount of cut and tied stem culm bundles.

[Conventional technology]

This type of stem culm bundle collection device was developed in Japanese Patent Application Publication No. 1983-
As disclosed in Publication No. 124527, the front part of the machine is equipped with a pulling device for raising planted stem culms, a reaping device for reaping the raised stem culm bundles, and a bundling of the cut stem culm bundles in a vertical position. It is known to have a configuration in which a binding device is provided, and a clamping and conveying device is provided behind the bundling device for lifting the stem culm bundle in a sideways posture and discharging it to a collecting section in the rear lower part in the sideways posture.

[Problem that the invention seeks to solve]

By the way, the above-mentioned stem culm bundle collecting device does not allow the tip side to sag due to the weight during transportation, or some stem culms separated from the stem culm bundle to get caught in the clamping and conveying device. The discharge posture is often greatly disturbed, which causes situations such as the discharged stem culm bundles placed on the collection unit not being aligned in the same direction and easily collapsing, and the amount that can be loaded reduced. I was afraid.

In consideration of the occurrence of such a situation, the present invention makes it possible to load the stem culm bundles onto the collection unit in a stable state and to a specified amount by aligning the transport posture and release posture of the stem culm bundles. The purpose is to make it possible.

[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 recovery unit is provided, and the released stem and culm bundle is temporarily received in a horizontal position at the rear of the terminal end of the clamping and conveying device. Thereafter, a receiving part for discharging to the collecting part is provided, and a rotary tool for raising and discharging stem culm bundles is arranged on the terminal tip side of the clamping and conveying device, which is driven and rotated around an axis substantially parallel to the culm direction. In addition, a shaft that can be rotated around an axis substantially parallel to the culm direction is protruded from the terminal end of the clamping and conveying device, and its functions and effects are as follows. be.

[Effect]

In other words, the bundled stem culm bundle is lifted and transported rearward and upward in a sideways position using a single clamping and conveying device, and when it reaches the end, the rotating tool for releasing the stem culm bundle is used to release the stem culm bundle so that the stem culm bundle hangs down. Raise the tip side of the grain to adjust the sideways posture of the grain culm bundle. Then, the trimmed stem culm bundle is discharged to the receiving section, where it is once received in a sideways posture, and then dropped and discharged to the collection section in a sideways posture. In addition, even if some stem culms separated from the stem culm bundle are caught in the path of the clamping and conveying device when the stem culm bundle is received by the receiving part, the base side of the stem culm is Since it is caught on the axis along the direction and detours upward, it is pulled by the weight of the stem culm bundle and the elastic restoring force of the separated stem culm itself, and can easily escape from the conveyance path.

〔Effect of the invention〕

As a result, the discharge posture of the stem culm bundle is adjusted, the disorder of the loading posture on the collection unit is improved, and the stem culm bundle can be loaded in a stable sideways posture, and can be loaded sufficiently to the specified amount. Ta.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in Figures 5 and 6, a reaping pre-processing section A of the same type as a combine harvester is installed at the front of a traveling machine based on a combine harvester, and a binding device B is installed at the rear of the unit. And control section 1
The holding and conveying device C is on the left side, and the collection section D is behind it.
A reaping and tying machine with a collecting device, which is an example of a stem culm bundle collecting device, is equipped with the following.

The reaping pre-processing section A includes a raising device 2 for raising a planted stalk culm, which is a type of stalk culm, a pair of puckers 3, 3 for scraping the raised grain culms toward the center, and a mowing device for mowing the scraped grain culms. The grain culm is composed of a reaping device 4 for harvesting the grain, a vertical conveying device 5 for conveying the harvested grain culm backward and upward while gradually turning it sideways.
The vertical conveyance device 5 consists of an ear-end locking conveyance device 5A that locks and conveys the tips of grain culms, and a stalk-clamping conveyance device 5B that conveys grain culms while clamping them. The culm is transported upward while lying on its side,
The stock head is sent to belts 6, 6 with protrusions for lifting the stock head placed at the left end of the machine body. A stock removal rod 7 is provided extending from the machine body to the starting end of the protruding belts 6, 6 for smooth stock feeding.

As shown in FIGS. 1 and 2, the belts 6, 6 with protrusions are arranged side by side in pairs on the left and right, and the belts 6, 6 with protrusions are arranged side by side in pairs on the left and right, and the belts 6, 6 with projections are arranged side by side in pairs on the left and right, and the belts 6, 6 with projections are arranged side by side in pairs on the left and right, and the belts 6, 6 with projections are arranged side by side in pairs on the left and right, and the belts 6, 6 with projections are arranged side by side in pairs on the left and right, and the belts 6, 6 with projections are arranged side by side in pairs on the left and right, and the belts 6, 6 with projections are arranged side by side in pairs on the left and right, and the belts 6, 6 with projections are arranged side by side in pairs on the left and right, and the belts 6, 6 with projections are arranged side by side in pairs on the left and right, and the belts 6, 6 with projections are arranged side by side in pairs on the left and right. While holding it, transport it backwards and upwards. At the end of the conveyance path of the protruding belts 6, 6 and before the grass collecting space of the binding device B, in other words, near the action end of the tip trajectory of the packer arm 8 of the binding device B, there is a grain culm stock source. Cutting device 9 for trimming edges
is provided. As shown in FIG. 3, this cutting device 9 has a long hole 10a formed in a long piece of an L-shaped link 10 that is rotatable around an axis _P1 .
Insert the pin 11a at the tip of the crank arm 11 into 0a, cut out an engaging part 10b at the tip of the short piece, and insert the pin 12 of the movable blade 12 into the engaging part 10b.
a is engaged with each other. According to this structure, when the crank arm 11 rotates, the link 10 swings in conjunction with the rotation, and the movable blade 12 engaged with the short piece slides relative to the fixed blade 13 to perform a cutting action.

A binding device B is disposed behind the ends of the belts 6, 6 with projections, and the grain culms that have been sent in a sideways posture are scooped in by the packer arm 8, converged and tied at the same time, and the grain culm bundles are bundled. Discharge backward using the discharging device 14. Incidentally, the belt with protrusions 6,
The terminal end of grain 6 and the tip trajectory of packer arm 8 partially overlap in side view so that the grain culm can be transferred smoothly. The discharge device 14 is a blade-shaped device that rotates around the left and right horizontal axis _P2 ,
Grain culm supply port 1 of the said conveying device C which pinches the action part
5 is on the way. This discharging tool 14 is designed to be driven to rotate at all times when the bundling device B is in operation, but immediately after discharging the grain culm bundle, it temporarily stops in front of the grain culm supply port 15 and closes the supply port 15. ,
Then, the supplied grain culm bundle can be reliably delivered to the clamping and conveying device C. In other words, since the clamping and conveying device C is tilted slightly backward and directed high, if the supplied grain culm bundle hits an undesired location and bounces back, or if the grain is not penetrated properly, the delivery will be delayed. There is a risk that it will fail and fall down from the grain culm supply port 15. Therefore, after the grain culm bundle is released, the discharge door 14 closes the grain culm supply port 15 for a certain period of time to help ensure that the grain culm bundle is clamped.

As already shown in FIG. 2, the clamping and conveying device C is provided with a chain case 16 that is high upwardly and slightly tilted backwards, and has a drive sprocket 17 at the lower end that is pivotally supported within the chain case 16 and a drive sprocket 17 at the upper end that is pivotally supported within the chain case 16. A chain 19 with protrusions is wound around the driven sprocket 18, and a holding rail 20 is provided along the chain 19 with protrusions exposed to the front side from the chain case 16. Further, the shaft 21 of the driven sprocket 18 is extended outside the chain case 16, and a rotary tool 22 for raising and discharging grain culms is attached to the end on the ear tip side, and a rotary tool 22 is attached to the shaft 21 on the stock side. A large-diameter rotating shaft 23 that is rotationally driven is fitted. Further, a receiving part E is provided at the rear of the upper end of the clamping and conveying device C, in other words, at the rear of the terminal end, for once receiving the grain culm bundle discharged from the device C in a sideways posture, and then releasing it all at once to the collecting section D. be.

Therefore, the grain culm bundles supplied to the grain culm supply port 15 are
It is conveyed upward and backward while being held by the protruding chain 19 and the clamping rail 20 in a sideways position, and when it reaches the end, it climbs over the rotary tool 22 and the rotating shaft 23 and falls once into the receiving part E, and is placed in a sideways position. After getting used to it, it falls and is released into the collection section D below. still,
When the grain culm bundle reaches the end of the clamping and conveying device C, the rotating tool 22 adjusts the release posture of the grain culm bundle by scraping up the tips of the grain culm bundles that have drooped down, and removes the grain culm bundles that have fallen into the receiving part E. This is to prevent the sideways posture from being disturbed. Additionally, if several grain culms that have come loose from the grain culm bundle remain on the conveyance path and are caught in the following grain culm bundle when the grain culm bundle falls to the receiving part E, the grain culm bundle is not received. This causes a large disturbance in the ejection posture when the ejector is released from the stopper E. Therefore, by providing the rotating shaft 23 on the stock side, the grain culms that are separated when the grain culm bundle is dropped and released to the receiving part E are hooked onto the rotating shaft 23, and the rotating shaft is transmitted through friction. The rotational force of 23, the weight of the grain culm bundle, and the elastic restoring force are used to pull the grain upward and assist the grain culm bundle to escape from the conveyance path, thereby preventing the grain culm bundle from being caught by subsequent grain culm bundles.

The receiving portion E includes a receiving plate 24 located behind the terminal end of the clamping and conveying device C so as to be vertically swingable around the left and right horizontal axes.
The receiving plate 24 can be locked in a horizontal position and can receive grain bundles dropped from the clamping and conveying device C, and the receiving plate 24 can be unlocked and released.
In other words, the receiving plate 24 is automatically switched to a state in which the weight of the grain culm bundle allows the receiving plate 24 to swing downward, allowing the grain culm bundle to fall and be released. . To be more specific, an L-shaped link 25 is rotatably attached to the side wall of the holding and conveying device C, a rod 26 is pivotally connected to the tip of one piece, and a pin 25a is formed at the tip of the other piece. It is brought into contact with the tip portion of an arcuate link 27 that swings integrally with the receiving plate 24. Further, a contact link 28 is pivotally attached to a side wall located below the L-shaped link 25 so as to be able to swing vertically, and its tip protrudes onto the conveyance path of the clamping conveyance device C, and the lower end of the rod 26 is pivotally supported. The L-shaped link 25 rotates in conjunction with the upward swinging of the contact link 28, and the contact pin 2
5a and the arc-shaped link 27 are released, that is, the lock of the receiving plate 24 is released. In short, in a state where the grain bundle is received on the receiving plate 24, when the following grain bundle contacts the contact link 28 on the lifting conveyance path and swings upward, the lock on the receiving plate 24 is released. As a result, the grain bundle on top of the grain bundle slides down from the receiving plate 24 due to its own weight (see Fig. 4). In addition, after the grain culm bundle is released by dropping, L
The shape link 25 and the contact link 28 are pushed back to the initial state by the spring 29, and the receiving plate 24 is also returned to the horizontal position by the spring 30 to return to its original locked state.

The recovery section D is configured to be dumpable around the axis _P3 at the rear end so that the loaded grain bundles in a sideways posture can be lowered to the ground all at once. Moreover, when the collecting section D dumps, the rear side plate 31 falls down and becomes flush with the bottom plate 32, so that the grain culm bundle can smoothly slide down to the ground.

Note that the present invention may be applied to a grain culm bundle collection device that scoops up and collects grain culms left in a horizontal position in a field.
