Description

[Detailed Description of the Invention] "Industrial field of application" The present invention picks up grass and straw scattered in a field with a pickup unit and forms them into a roll-shaped bale by a bale shaping conveyor of a bale forming unit. Regarding roll balers.

"Prior Art" Conventionally, as disclosed in Japanese Utility Model Laid-Open No. 59-166639, there is a means for opening the rocker frame at the upper part of the bale chamber to take out the bale from the bale forming chamber.

"Problems to be solved by the invention" In the above-mentioned conventional technique, not only is it necessary to lift the upper bale shaping conveyor to open the bale outlet,
The bail also needs to be lifted up and taken out, and there is a drawback that the bale taking out work cannot be performed easily.

[Means for Solving the Problems] Therefore, the present invention is a veil take-out device for a roll berla that forms straw grass picked up by a pickup part into a roll-shaped bale by a bale shaping conveyor of a bale forming part. The side plate of is attached so that it can move up and down,
It is characterized in that a bale outlet is opened on the side surface of the bale forming chamber by the upward movement of the side plate to form a bale outlet having a size such that the side surface of the bale is entirely opened.

[Action] Therefore, since the bale is taken out to the side of the bale forming chamber, it is not necessary to lift the bale, and the taking-out operation can be performed very easily, and by opening the side plate upward, the side plate obstructs the bale taking-out work. Not only that, the work can be performed safely and efficiently, and the internal inspection can be performed conveniently.

It is configured to send. The straw grass fed into the bale forming chamber (18) is rolled into a bale by the rotation of the conveyors (16) and (17).
(A) is formed, and the bale (A) is bound by the twine fed from the bundling device (10) on the outer periphery of the bale (A) and is taken out of the bale forming chamber (18). Is.

Also, the sprocket shaft of the drive sprocket (19) (24)
Power input sprocket (36) integrally fixed to (19a) (24a)
(37) is linked to the sub-counter shaft (38) through the chains (39) (40), and the sub-counter shaft (38) is connected to the main counter shaft (41) on the engine side by the chain (42). Interlocking connection through the main and sub shaping pipe conveyor (1
6) (17) and the pickup finger (35) are simultaneously rotated.

As shown in FIG. 4, a bale extruding plate (43) is provided on the right side of the bale forming chamber (18) and an open side plate (44) is provided on the left side thereof, and the extruding plate (43) is provided substantially at the center. The spherical concave portion (45) is rotatably fitted to the spherical convex portion (47) at the tip of the discharge arm (46), and the base end of the arm (46) is attached to the bale discharge shaft (48) having the feed screw (48a). When the driving force from the input sprocket (50) is transmitted to the discharge shaft (48) through the discharge clutch (49), the pushing plate (43) is reciprocally moved left and right in the bale forming chamber (18). is doing.

Also, the upper plate (51) of the baler part (3) is a baler part body (3).
It is connected to the front side of a) via a hinge (52) and is provided so that the upper part of the baler part (3) is opened when the upper plate (51) is moved upward by the handle (53) provided on the rear side of the side plate (51). ing. Then, a formation chamber cover plate (54) that covers the left side of the bale formation chamber (18) is integrally hung on the left side portion of the upper plate (51), and an electric motor (55) fixed to the cover plate (54) has a rotary screw. The open side plate (44) is connected and supported via a shaft (56) and a screw connector (57), and the open side plate (44) is bale-formed by driving the motor (55) when the upper plate (51) is opened. It is configured to retreat from the chamber (18), move upward while avoiding interference with the main body (3a) side member, and open the bale outlet (58) on the left side of the bale forming chamber (18). . By the way, the sprocket (19) (24) that drives each conveyor (16) (17)

The present embodiment is configured as described above, the straw picked up by the pickup unit (4) is carried into the bale forming chamber (18) by the lower shaping pipe conveyor (16),
Rolled bale with each pipe conveyor (16) (17)
Formed in (A). After the bale formation is completed, the motor (54) is driven to retract the open side plate (44) from the inside of the bale forming chamber (18) to avoid interference with the main body (3a) side member, and the upper side plate (51). Bale forming chamber (18)
Open the bale outlet (58) on the left side, and then open the discharge shaft.
When the push plate (43) is moved to the bale outlet (58) side by the rotation of (48), it pushes the bale (A) out of the machine, and the straw grass picked up by the pickup part (4) is used for the bale forming part. (3) Bale (A) shaping conveyor (16) (17) in the bale take-out device of the roll bale to form a bale (A) roll, in the bale forming chamber (18) one side plate (44) up and down The bale forming chamber (1
8) The bale outlet (58) is opened on the side surface to form a bale outlet (58) of such a size that the entire side surface of the bale (A) is opened.

Thus, even if the left side plate of the bale forming chamber (18) is moved as in the above configuration, all the drive systems such as the conveyors (16) and (17) are biased to the right side. Since they are arranged, good crops can be obtained without any hindrance to each other.

FIG. 5 shows another modified structure example, in which the cover plate (54) is formed in a substantially semicircular shape and the open portion above the baler portion (3) is made large. (16) Convenient for inspection and maintenance of (17). As shown in FIG. 6, the upper and lower plates (51) together with the left and right side plates (44a) (44b) of the bale forming chamber (18) are provided so as to be open upward, and the drive system is provided on the lower body (3a) side.
The bale forming chamber (18) may be configured so that the front surface is open.

[Effect of Device] As is apparent from the above-described embodiment, the present invention uses the bale (A) of the bale forming unit (3) to collect the straw grass picked up by the pickup unit (4).
Rolled bale (A) by shaping conveyors (16) (17)
In the bale take-out device of the roll baler to be formed in, the side plate (44) on one side of the bale forming chamber (18) is attached so as to be vertically movable,
By moving the side plate (44) upward, a bale outlet (58) is opened on the side surface of the bale forming chamber (18) to form a bale outlet (58) of such a size that all side surfaces of the bale (A) are open. Since the bale (A) is taken out to the side of the bale forming chamber (18) with this structure, it is not necessary to lift the bale (A) and the taking out work can be easily performed, and the takeout opening (58) The side plate (44) that forms the
(A) It is safe and has excellent workability without hindering the taking-out work, and has an effect that internal inspection and cleaning can be conveniently performed.
