Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a bale forming chamber structure of a roll baler in which a bale forming chamber is enlarged when taking out a bale.

[Conventional technology]

Conventionally, as seen in Japanese Patent Application No. 61-37922 (No. Sho 62-149934), which the applicant has already filed, a bale is formed while carrying straw grass on the outer peripheral rear side of the bale formation chamber. In the roll baler, which is configured by rotatably arranging the side-arc-shaped front pipe conveyors that form a bale while conveying straw on the side-arc-shaped rear pipe conveyors on the front side, when removing the bale, The structure was such that the rear pipe conveyor moved outward.

[Problems to be solved by the invention]

With such a structure, the bale forming chamber is expanded, but its movement is limited and the front pipe conveyor does not move. It has a problem that it cannot be taken out smoothly because it gets caught on the conveyor depending on conditions such as type and dryness.

[Means for solving problems]

The present invention solves the problem and allows the bale forming chamber to be sufficiently enlarged so that the bale can be taken out smoothly and satisfactorily. Therefore, the upper part and the front part of the rear pipe conveyor are The upper part of the pipe conveyor is configured to be movably interlocked with each other in association with the opening of the door laterally of the bale forming chamber so that the upper part of the pipe conveyor rotates around the lower fulcrum and separates outward. .

[Action]

Therefore, when removing the bale, when the door is opened, the upper parts of both conveyors are interlocked with each other to move outward and open, and the bale forming chamber is wide enough so that the bale can be taken out smoothly. Become.

〔Example〕

Next, the embodiment shown in FIGS. 1 to 6 will be described.

FIG. 2 shows a side view of the whole roll baler, and the baler part (C) mounted on the machine body supported by both crawlers (4).
A pickup drum (6) having a finger (5) that can freely move in and out and a pickup portion (D) provided with a guide plate (7) are vertically arranged in a row below the front side of the baler portion (C). A drive unit (E) equipped with an engine (8) and various operating levers (9) is installed in the rear of () to have the same structure as the conventional structure.

The bail portion (C) is provided with a bale forming chamber (B) for forming the bale (A) at an inner central portion thereof, and a guide frame (which has an arc shape like that is formed on the outer periphery of the rear part of the bale forming chamber (B). the lower part of 10) and pivoted on a fulcrum (0 _1), the rear of the guide frame Cheng (bale forming pipe 11) (12) and the conveying plate (rear pipe conveyor formed by bridging a 13) (1) (Ten)
The front end (1b) of the rear pipe conveyor (1) so as to be close to the rear of the pickup drum (6), and the outer periphery of the front part of the bale forming chamber (B). The fulcrum is the lower part of the guide frame (14) that is arcuate
A front pipe conveyor (2) pivotally supported on (0 ₂ ) and formed by erection of a bale forming pipe (15) is hung on the guide frame (14), and one side of the bale forming chamber (B). Door (3) that can be opened and closed while rotating around the vertical support shaft (16)
And a bail push-out (17) vertically movably arranged on the other side of the bale forming chamber (B) opposite to the door (3).

A bundling device (18) is provided inside the front part of the baler part (C), and is provided on the upper part (14a) of the guide frame (14) for hanging the upper part (2a) of the front pipe conveyor (2). , A guide frame (10) for linking the lower part of the link (20) that can rotate around the central support shaft (19) with play and interlockingly connecting the upper part (1a) of the rear pipe conveyor (1) One end of the rod (21) is interlockingly connected to the upper part (10a) of the rod (21), and the other end of the rod (21) is interlockingly connected to the upper part of the link (20). ) Has a link (2
2), a rotary plate (23), and a link (24), and is linked and linked to an arm (26) coaxial with the rotating arm (25).

Further, a connecting plate (30) is interlockingly connected to the rotating arm (27) of the support shaft (16) via a rod (28) and a rotating plate (29), and is connected to the rotating arm (25). The bale compression spring (31) is interposed between the connecting plates (30), but the connecting plates (3
The screw (3) that is rotated by the handle (32)
3) is mounted on the shaft and screwed into the screw (33).
The lower part of the connection (35) is fixed to 4), and the lower end of the spring (31) whose upper end is connected to the tip side pin (36) of the rotating arm (25) is connected to the upper part of the connection (35). When the scale (37) indicating the upper position of the connection (35) is provided on the connection plate (30) and the door (3) is closed, the connection plate (30) moves downward in FIG. With said spring (31)
While moving the link (24) downward through the rotating arm (25) and the arm (26) by the pulling force of
It is possible to move both pipe conveyors (1) and (2) in a direction in which they move toward each other to repress, and when the door (3) is opened,
While the connecting plate (30) moves upward in FIG. 1 and engages with the link (24) at the upper end of the connecting plate (30), the link (24) moves upward in FIG. Both pipe conveyors (1) and (2) are configured to be movable in directions away from each other.

Therefore, at the time of work, the rear pipe conveyor (1) carries the straw grass picked up by the pickup drum (6) into the bale forming chamber (B) while the rear pipe conveyor (1) indicates the arrow (a). Also, the front pipe conveyor (2) rotates as shown by the arrow (b), and rolls (A) in the bale forming chamber (B) as in the conventional type.
Will be formed.

When the bail (A) is formed, the door (3) is opened and pushed out by the bale push-out (17), but as the door (3) is opened, the support shaft (16) is rotated to operate the interlocking mechanism. Then, the link (22) pulls the upper part (10a) of the guide frame (10) outward as shown by the arrow (c), and the rod (21) rotates the link (20) to guide the guide frame ( The upper part (14a) of 14) is to be moved outward as indicated by the arrow (d), and as shown in FIG. 6, the upper part (1a) of the rear pipe conveyor (1) is indicated by the arrow (h). ), Also the front pipe conveyor (2)
The upper part (2a) of each of them moves respectively as shown by the arrow (f) to expand the bale forming chamber (B), and the bale (A) can be taken out of the machine without any trouble.

By adjusting the spring (31) according to the scale (37) by operating the handle (32), it is possible to freely select a packing pressure suitable for the condition and method of the crop.

FIG. 7 to FIG. 9 show another example. Instead of the pickup drum of the above-mentioned embodiment, the starting end portion (1b) of the rear pipe conveyor (1) is shortened so as to be below the bale (A).
Both chains (38, 38) are rotatably installed in the front of the chain, and spring fingers are attached to the upper surfaces of the supports (39) that are laid horizontally across the chains (38, 38) at regular intervals. (Four
0) are attached, and a guide plate (41) is stretched around the outer circumference of the guide plate (41). As shown in FIG. 7, each finger (40) extends from the front side to the middle of the rear side of the guide plate (41). It is configured so that it can be projected and picked up the straw grass to be conveyed backward, and at the rear side, it can be retracted inside the guide plate (41) and separated from the straw grass.

[Effect of device]

Thus, according to the present invention, the upper part (1a) of the rear pipe conveyor (1) and the upper part (2a) of the front pipe conveyor (2) can be moved to the outside in conjunction with the opening of the door (3). As a result, the bale forming chamber (B) can be expanded sufficiently so that it does not hinder the removal of the bale (A), and the bale can be reliably and smoothly irrespective of the type of material and the conditions of the wet and dry materials. Since (A) can be taken out, the workability can be further improved, and it has a feature that it can be suitably implemented.
