Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a reaping and tying machine with a collection device capable of holding a bundle of stems and culms that have been cut and tied.

[Conventional technology]

As a reaping and binding machine with a collection device of this type,
-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 culms, and a binding device for tying the cut stem culms in a vertical position. and behind them,
A device is known that is equipped with a lifting and conveying device that lifts the stem culm bundle in a sideways position and releases it to a collection section located below the rear in a sideways position.

[Problem that the invention seeks to solve]

By the way, in the above-mentioned reaping and tying machine with a collection device, the stem culm bundle released from the tying device is lifted by the lifting and conveying device and immediately discharged to the collection section, so S! The placed stem and culm bundles were not aligned and were prone to collapse (which could reduce the load capacity).

An object of the present invention is to enable a specified amount of stem and culm bundles to be stacked on the collection unit in an orderly manner by enabling the lifted and transported stem and culm bundles to be discharged to the collection unit in a stable posture.

[Means for solving problems]

Characteristic configurations of the present invention include: a pulling device for causing planted stem culms at the front of the machine; a reaping device for reaping the raised stem culms; and a binding device for binding the cut stem culms.
In a reaping and tying machine equipped with a collection device, which is equipped with a lifting and conveying device that lifts the bundled stem culms in a horizontal position and discharges them to a collecting section located below the rear, the stem culm bundle immediately after being released from the lifting and conveying device is A receiving mechanism is provided which receives and supports the stem in a sideways position and then releases it by dropping it toward the collecting section. and a fixed guide that broadly locks the stem culm bundle placed on the receiving tool in the culm length direction from the rear upper side, and the stem culm bundle retaining working position is such that the receiving tool is tilted slightly backwardly. , and thick downwards (
The structure is such that it can be freely switched between the oscillating discharge positions and its functions and effects are as follows.

(Function) According to the above configuration, the stem culm bundle lifted by the lifting and conveying device is placed sideways on the receiving part and is temporarily stopped from being received.
At this time, since the receiving device is inclined slightly backwardly, the stem culm bundle slides down toward the rear free end side of the receiving device under its own weight, and is supported by a fixed guide that locks from above. For this reason, the stem culm bundle assumes a fixed sideways posture by being placed and supported by the receiver and the fixed guide that act widely in the direction of the culm. Thereafter, as the receiving tool swings downward to open, the stem culm bundle falls onto the collecting section in a predetermined sideways posture.

〔Effect of the invention〕

Therefore, according to the present invention, the stem culm bundle is subjected to a posture correcting action by the holding device, the fixed guide, and the dowel between the time it is lifted by the lifting and conveying device and the time it is released to the collecting section. After stabilizing the sideways posture, it becomes possible to discharge the stem culm bundles onto the collecting section and stack them up in an orderly manner.As a result, the top of the collecting section can be fully utilized and a large amount of stem culm bundles can be loaded and collected in a good manner. Now you can.

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

As shown in FIGS. 1 and 2, 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 (1) is mounted behind it to constitute a reaping and tying machine with a collecting device.

The reaping pre-processing section (A) includes a raising device (2) that raises a planted culm, which is a type of stem culm, and a pair of bunkers (3) that scrape the raised culm toward the center.
, a reaping device (4) for reaping the raked culm, and
It consists of a vertical conveyance device (5) that conveys the cut culm backwards and upwards while gradually turning it sideways. The vertical conveyance device (5) consists of a tip locking conveyance device (5A) that locks and conveys the tip of the culm, and a plant head clamping conveyance device (5B) that conveys the plant head while clamping it. (6)

, (6) is provided over 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 3 and 4, and are located at the base of the sent culm (Sa). is conveyed backward and upward while being held in the lower path. In other words, at the end of the conveyance path of the protruding bell) (6) and (6) and before the grass collection space of the binding device (B), there is a bell with a protrusion (6), and in front of the grass collection space of the binding device (B), in other words, the tip of the packer arm (8) of the binding device (11) A cutting device (9) for trimming the base end of the shell culm (Sa) is provided near the working end. As shown in FIG. 5, this cutting device (9) has a long hole (10a) formed in a long piece of an L-shaped link (lO) that is rotatable around an axis (PI). Insert the pin (lla) at the tip of the crank arm (11) into the hole (10a), cut out a retaining portion (10b) at the tip of the short piece, and insert the movable blade (1) into the engaging portion (10b).
2) is engaged with the bottle (12a). According to this structure, when the crank arm (11) rotates, the link (lO) swings in conjunction with it, and the movable blade (12) engaged with the short piece slides relative to the fixed blade (13). The cutting action takes place.

A binding device (8) is arranged behind the end of the protruding belts (6), (6), and the packer arm (8) scrapes the sent shell culm (Sa) in a sideways posture. The shell culm bundle (S) is focused and tied at the same time, and released backward using the release door (14).

Note that the protruding bell (6), (6) and the tip trajectory of the packer 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 (P2), and its operating portion faces the culm supply port (15) of the lifting and conveying device (C). be. This discharge door (14) is always rotated when the binding device W (B) is in operation, but the culm bundle (
Immediately after releasing the shell culm bundle (S), the system temporarily stops in front of the shell culm supply port (15), closes the supply port (15), and then transfers the supplied shell culm bundle (S) to the lifting and conveying device (C). To ensure that the delivery can be carried out reliably. In other words, since the lifting and conveying device (C) is of a pinching conveyance type and is directed upward, the supplied culm bundle (S) may hit an undesired place and tumble or bite. If it is bad, 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 (1
4) closes the shell culm supply port (15) for a certain period of time to help securely clamp the shell culm bundle (S).

As already shown in FIG. 3, 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) extends between the driving sprocket (17) and the driven sprocket (18) at the upper end.
), and a clamping rail (20) is provided along the protruded chain (19) exposed to the front side from the chain case (16). Also, the shaft (21) of the driven sprocket (1B) is connected to the chain case (1
6) A rotary tool (22) for lifting and releasing the culm is attached to the end of the tip of the ear, and a large diameter rotary tool (22) is attached to the end of the shaft for raising and releasing the culm. axis of rotation (23
) is fitted. Further, the culm bundle (S) 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 is temporarily stopped in a sideways position, and then the collecting section (D) A receiving part (E) is provided for discharging to air.

Therefore, the culm bundle (S) supplied to the culm supply port (15)
is conveyed upward and rearward in a horizontal position while being held between the chain with protrusions (19) and the holding rail (20), and when it reaches the end, it passes over the rotating tool (22) and the rotating shaft (23) and is once transferred to the receiver. After falling into the stopping mechanism (IE) and falling to a sideways position, it is released by falling to the collecting section (D) below. still,
The rotating tool (22) adjusts the release posture of the culm bundle (S) by scraping up the drooping tip when the culm bundle (S) reaches the terminal end of the lifting and conveying device (C), and moves the culm bundle (S) to the receiving part. This is to prevent the sideways posture of the shell culm bundle (S) that fell in (E) from being disturbed. In addition, the culm bundle (S) is connected to the receiving mechanism (E
), if several culms separated from the culm bundle (S) remain on the conveyance path and are caught in the following culm bundles, the culm bundle (S) is caught by the mechanism (E). This causes the release posture to be greatly disturbed when the product is dropped and released. Therefore, by providing the rotating shaft (23) on the stock side, when the shell culm bundle (S) falls and is released to the receiving mechanism (E), the separated shell culms are caught on the rotating shaft (23). The rotational force of the rotating shaft (23) transmitted through friction, the weight of the culm bundle (S), and the elastic restoring force are used to pull the shell culm bundle (S) upward and assist in removing it from the conveyance path.
This prevents it from getting caught in the subsequent shell culm bundle (S).

The receiving mechanism (E) includes a rearward cantilevered receiving tool (24) that is vertically swingable around the horizontal axis (P3) at the rear end of the lifting and conveying device (C), and C
) is a backward cantilever fixed guide (33
). The receiving tool (24) is made of a wide plate material in the direction of the culm of the stem culm bundle, and can be switched between a stem culm bundle receiving working position with a slight downward slope and a releasing position in which it swings significantly downward. It is free to move. Further, the fixed guides (33) are provided in two on the left and right so as to act widely on the stock side and the tip side of the stem culm bundle (S), and the respective rear ends are in the stem culm receiving position. The stem culm bundle (S), which extends to near the rear end of the tool (24), is released onto the receiving tool (24), and has slipped one step backward is stopped by the fixed guide (33) from behind and laid down in a predetermined position. It is constructed to maintain a stable posture.

Further, the receiving device (24) is configured to automatically switch between the stem culm bundle receiving posture and the releasing posture, and the structure thereof will be described below. That is, an L-shaped link (25) is rotatably attached to the side wall of the lifting and conveying device (C), a rod (26) is pivotally connected to the tip of one piece, and the rod (26) is pivotally connected to the tip of the other piece. A pin (25a) is formed and is brought into contact with the tip of an arcuate link (27) that swings integrally with the receiving plate (24). In addition, a contact link (
The rod (28) is pivotally mounted to be able to swing up and down, with its tip protruding onto the transport path of the lifting and transporting device (C), and the lower end of the rod (26) is pivotally connected, thereby connecting the contact link (2
The L-shaped link (25) rotates in conjunction with the upward swing of 8), and the contact between the contact pin (25a) and the arcuate link (27) is released, that is, the catch (24) is locked. is now being released.

In short, in a state where the shell culm bundle (S) is received on the receiving tool (24), the following shell culm bundle (S) comes into contact with the contact link (28) on the lifting and conveying path and is shaken upward. When it moves, the lock of the catch (24) is released and the culm bundle (S) above it slides down from the catch (24) under its own weight (see Fig. 6). In addition, after dropping and releasing the culm bundle (S),
The L-shaped link (25) and the contact link (28) are returned to their initial states by the spring (29), and the catch (24) is also returned to its horizontal position by the spring (30), returning to its original locked state. become.

The recovery section (D) is configured to collect the loaded shell bundles (
The rear end shaft center (P4
) can be configured to dump around.

Furthermore, when the recovery section (D) dumps, the rear plate (31) falls down and becomes flush with the bottom plate (32), allowing the culm bundle (S) to slide down smoothly to the ground.
