Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a roll baler that compresses and packs collected materials such as cut down grass and threshed waste straw into a roll shape.

Prior Art A conventional roll baler is a cart equipped with a bale chamber for compressing and packing collected material into a roll, as described in Japanese Utility Model Application Publication No. 1987-87245 filed and published by the applicant. A structure in which the index is indexed by a tractor, or a structure in which the
As described in Japanese Patent No. 166636, there is a structure in which the bale chamber is mounted on a self-propelled trolley and runs directly on it.

Problems to be Solved by the Invention Since the conventional roll baler as described above is composed of one bale chamber, it is difficult to move the packed bale outside the bale chamber during the operation of winding string around the compression-molded rolled bale. During the removal process,
The collection work must be interrupted by stopping the aircraft, reducing work efficiency. This decrease in work efficiency is due to
When collection work is performed using a small self-propelled roll baler, the amount of time the machine is stopped is significant as a proportion of the total work time.

Means for Solving the Problems In order to solve the above problems, the present invention is configured as follows.

That is, at the rear of the pick-up device 1 that picks up collected items on the ground, bale chambers 2 and 3 for bundling collected items into rolls are installed side by side on the left and right, and these left and right bale chambers 2 and 3 have separate inner cavities. A conveying device configured to be able to open and take out the collected material formed into a roll, and located between the pick-up device 1 and the left and right bale chambers 2 and 3 to transport the collected material into the bale chambers 2 and 3. A guide member 5 is provided on top of the guide member 4 to appropriately switch the guide direction of the collected material to one of the left and right bale chambers 2 and 3.

Operation According to the above configuration, the collected material picked up by the pick-up device 1 is sent to one of the left and right bale chambers 2 and 3 by the conveying device 4 and the guide 5, and is compression-molded into a roll-shaped bale, and the compression-molding is completed. Then, while continuing the collection work by switching the guide 5 to send the collected items to the other bale chamber, the bales in one bale chamber can be tied with strings, packed, and taken out of the machine.

Effects of the Invention As described above, even when the bales in one bale chamber are being tied with a string and taken out of the machine, the collecting operation can be continued while running outside the machine, and compression molding can be performed in the other bale chamber. The time required to interrupt collection work is short, and work efficiency can be further improved compared to conventional roll balers.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

The chassis 6 is a self-propelled type equipped with a traveling device consisting of a crawler 7, and is equipped with a bail section 8 consisting of bail chambers 2 and 3 having the same internal volume on the left and right sides of the front, and a bail section 8 on the rear. It is equipped with a driving unit 9 that has a built-in prime mover and the like.

Further, a pick-up device 1 that approaches the ground and picks up collected items is provided at the front of the vehicle platform 6, and a conveyance device 4 is provided between the pick-up device 1 and the bale chambers 2 and 3.

The pick-up device 1 is configured such that the pick-up rod 11, which is pivotally supported at an eccentric position in the inner cavity of the cylindrical body 10, rotates upward while appearing and retracting from the circumferential surface of the cylindrical body 10 as the cylindrical body 10 rotates. is a rod-shaped conveyor 12 with protrusions of endless chains stretched on the left and right sides.
It is constructed by horizontally suspending a large number of panels so that the upper surface moves from the bottom to the top.

The left and right bale chambers 2 and 3 have substantially the same structure, and are formed by a lower conveyance device 13, an upper conveyance device 14, and disk-shaped side walls 15, 15 provided on the left and right sides. These lower conveying device 13 and upper conveying device 14 are constructed by horizontally suspending a large number of rod-shaped conveying tools on endless chains stretched on the left and right sides, and the left and right endless chains extend in a circle along the outer periphery of the side wall 15. It rotates in an arc.

The upper halves of the left and right bale chambers 2 and 3 are configured such that their rear parts are flipped upwards about the front shaft 16, so that the inner cavities are opened individually.

Further, a twine supply device 17 is provided at the rear of the left and right bale chambers 2 and 3, and a string 18 is supplied into the bale chambers 2 and 3 from between the lower conveyance device 13 and the upper conveyance device 14 to form a roll. The bales are packed using compression molding.

The twine supply device 17 has a twine guider 20 fitted onto a lead shaft 19 provided with left and right screws.The twine supply device 17 has a twine guider 20 fitted onto a lead shaft 19 provided with left and right screws. The string 18 is then moved back and forth right and left just behind the left or right bale chambers 2 and 3 to wrap the string 18 around the bale.

A guide body 5 made of a plate is provided on the upper part of the conveying device 4 to guide the collected material transferred on the conveying device 4 to one of the left and right bale chambers 2 and 3. This induction body 5 is pivotally attached to the center of the bale chambers 2 and 3, and is connected to a switching lever 21 of the driving section 9 by a wire 22, so that the front side thereof swings left and right in conjunction with switching of the switching lever 22. I try to guide the collected items to the empty veil room.

A pair of left and right levers 2 protruding above the driving part 9
3 and 23 are steering levers for controlling the chassis 6.

Note that the guide body 5 may be replaced with the illustrated plate body, and may be replaced by a conveying belt with protrusions, so that the collected items are forcibly moved to the side while being conveyed.

Next, the working conditions of this roll baler will be explained.

The collected items picked up by the pick-up device 1 while the vehicle platform 6 is traveling are transferred to the conveyor device 4 and the guide 5.
is fed into one of the left and right bale chambers 2 and 3 and compressed into a roll shape. When the compression molding of the collected material is appropriate, the switching lever 21 is operated so that the guide 5 guides the collected material to the empty bale chamber. After that, the twine supply device 1
7 is activated to pack the rolled bale and take it out of the machine. During this operation, the compression molding of the collected material continues in the other bale chamber, but once the compression molding is completed, the collection work continues in the same manner as described above.
