〔Example〕

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

As shown in FIGS. 5 and 6, a reaping pre-processing section (A) of the same type as a combine harvester is attached to the front part of a traveling machine based on a combine harvester, and a binding device (B) is provided at the rear part thereof. Furthermore, a lifting and conveying device (C) is mounted behind it and to the left side of the control section (1), and a collecting section (D) is mounted behind it to create a reaping and tying machine with a collecting device, which is an example of a stem culm bundle collecting device. It consists of:

The reaping pre-processing section (^) includes a raising device (2) that raises a planted shell culm, which is a type of stem culm, and a pair of packers (3) that scrape the raised shell culm toward the center.
It consists of a reaping device (4) that reaps the collected culms, a vertical conveyance device (5) that transports the cut culms backward and upward while gradually turning them sideways. The vertical conveyance device (5) is composed of a tip locking and conveying device (5A) that locks and conveys the tip of the culm, and a plant head clamping and conveying device (5B) that conveys the plant head while holding it. The culm, which is in a vertical position, is transferred upward while being turned sideways, and the culm is placed on the left end of the fuselage by a belt with a protrusion for lifting the culm (6).
Send to (6). In addition, the stock removal rod (7) for smooth stock feeding is attached to the protruding belt (6) from the machine body.
(6) is provided across the starting end side.

The protruding bells) (6) and (6) are arranged side by side in pairs on the left and right, as shown in Figures 1 and 2. It is conveyed backward and upward while being held in the path. This bell with a protrusion)
(6), In other words, at the end of the conveyance path of (6) and before the grass collecting space of the binding device (B), the binding device (
A cutting device (9) for trimming the base end of the culm is provided near the operational end of the tip trajectory of the packer arm (8) in B).

This cutting device (9) has a shaft center (P
l) Form a long hole (10a) in the long piece of the L-shaped link (10) that can freely rotate around it, and insert the bottle (lla) at the tip of the crank arm (11) into the long hole (LOA). In addition, an engaging part (10b) is cut out at the tip of the short piece, and a pin (12a) of the movable blade (12) is engaged with the engaging part (10b). According to this structure, when the crank arm (11) rotates, the link (10)
swings, and the movable blade (12) engaged with the short piece slides relative to the fixed blade (13) to perform a cutting action.

A bundling device (B) is arranged behind the end of the protruding bell) (6) and (6), and when the culm that is sent in a sideways posture is scooped in and bundled by the packer arm (8), At the same time, the grain culm bundles are bundled and released rearward using the release door (14). In addition, the bell with the protrusion) (6)
(6) The terminal end and the tip trajectory of the puff car arm (8) are partially concave in side view so that the culm can be transferred smoothly. The discharge door (14) is a blade-shaped member that rotates around the left and right horizontal axes (Pl), and its operating portion faces the culm supply port (15) of the lifting and conveying device (C). be. This release door (14) is a tie bag! During the operation of (B), it is constantly driven to rotate, but immediately after releasing the grain culm bundle, it is temporarily stopped in front of the shell culm supply port (15), and the supply port (15) is closed. , to ensure that the supplied grain culm bundle can be delivered to the lifting and conveying device (C). In other words, since the lifting and conveying device (C) is a clamping conveyance type and is oriented upward, the supplied grain culm bundle may hit an unwanted place and rebound ↑Ω, or if the feeding is poor. There is a risk that the delivery will fail and the culm will fall down from the culm supply port (15). Therefore, after releasing the grain culm bundle, the release door (
14) closes the shell 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. 1, the lifting and conveying device (C) is provided with a chain case (16) that is high upwardly and slightly tilted backwards, and has a lower end that is pivotally supported within the chain case (16). A chain with protrusions (19) is wound around the driving sprocket (17) and the driven sprocket (18) at the upper end, and a chain with protrusions (19) is wound along the chain with protrusions (19) exposed to the front side from the chain case (16). It is configured by providing a clamping rail (20). Also, the shaft (21) of the driven sprocket (18) is connected to the chain case (16).
It extends outward, and a rotary tool (22) for lifting and releasing the culm is attached to the end on the tip side, and the shaft (22) is attached to the stock side.
1) is fitted with a large-diameter rotating shaft (23) that is driven to rotate integrally with the main body. Furthermore, the grain culm bundle discharged from the lifting and conveying device (C) is placed on its side at the rear of the upper end, in other words, at the rear of the terminal end, and the grain bundle is once received in a sideways position, and then transferred to the collecting section (D) with air. A receiving part (E) is provided to release the water into the air.

Therefore, the grain culm bundle supplied to the culm supply port (15) is conveyed upward and rearward in a horizontal position while being held by the chain with protrusions (19) and the clamping rail (20), and when it reaches the end, it is rotated. After climbing over the tool (22) and the rotating shaft (23) and once falling into the receiving part (H) and lying on its side, it is released by falling to the collecting part (D) below. The rotating tool (22) adjusts the release posture of the grain culm bundle by scraping up the drooping tips when the grain culm bundle reaches the terminal end of the lifting and conveying device (C), and sends the grain culm bundle to the receiving part (E). This is to prevent the fallen grain culm bundle from falling into disarray. In addition, if several shell culms that have come loose from the grain culm bundle remain in 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 cannot be received. When the grain is released from the stopping part (E), it becomes thick (causing disturbance). Therefore, by providing the rotating shaft (23) on the stock side, the grain culm bundle falls to the receiving part (E). The culm, which is separated during release, is placed on the rotating shaft (
23) A rotating shaft (23) that is hooked onto the top and transmitted through friction
), the weight of the grain culm bundle, and the elastic restoring force are used to pull the grain upward, assisting the removal from the conveyance path, and preventing the grain culm bundle from getting caught in subsequent grain culm bundles.

The receiving portion (E) includes a receiving plate (24) located behind the terminal end of the lifting and conveying device (C) so as to be vertically swingable around the left and right horizontal axis.
The receiving plate (24) can be locked in a horizontal position to receive grain bundles dropped from the lifting and conveying device (C), and the receiving plate (24) can be unlocked to receive the grain bundle dropped from the lifting and conveying device (C). 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 upward and release the grain culm bundle. ing. In detail,
An L-shaped link (25) is rotatably attached to the side wall of the lifting and conveying device (C), and a rod (26) is pivotally connected to the tip of one piece of the L-shaped link (25). )
, and is brought into contact with the tip 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 transport path of the lifting transport device (C), and the rod The lower end of (26) is pivotally connected to the L-shaped link (25) in conjunction with the upward swinging of the contact link (28).
rotates, and the hit bottle (25a) and arcuate link (27)
The abutment of the receiving plate (24) is released, that is, the lock of the receiving plate (24) is released. In short, in a state where the grain culm bundle is received on the receiving plate (24), when the following grain culm bundle contacts the contact link (28) on the lifting and conveying path and swings upward, the receiving plate (24) is released and the grain bundle above it slides down from the receiving plate (24) under its own weight (see Figure 4). Furthermore, after the grain bundle is released, L
The shape link (25) and the contact link (28) are returned to the initial state by the spring (29), and the receiving plate (
24) is also returned to the horizontal position by the spring (30) and returns 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. Furthermore, when the collecting section (D) dumps, the rear side plate (31) falls down and becomes flush with the bottom plate (32), allowing the grain culm bundle to slide down smoothly to the ground.

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