Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a roll baler that collects collected materials such as cut down grass and threshed straw left on the ground and packs them into rolled bales.

(Prior art) As a roll baler, for example,
There is a structure described in 45792 publication.

In this roll baler of known structure, a bale chamber for compression-molding the collected material into a roll shape is composed of a bundling conveyance device that moves in an arc shape to give rotational motion to the collected material, and disk-shaped left and right side wall plates. A side wall plate is provided rotatably about the center line of the bale chamber, and one of the left and right side wall plates moves inward and outward as the bale chamber is opened and closed. A hydraulic cylinder is used to move the side walls in and out.

(Problem to be solved by the invention) The above-mentioned known roll baler is equipped with a hydraulic pressure generating device such as a hydraulic pump, so the side wall plate can be moved using hydraulic pressure, but the entire machine body is large. It becomes an expensive roll baler.

In recent years, roll balers that form small and lightweight bales have been developed, but these roll balers are not equipped with a hydraulic pressure generator.

Therefore, the present invention allows the side walls to move inward and outward with a simple structure without using hydraulic pressure.

(Means for Solving the Problems) In the present invention, a hollow cylindrical bail chamber is provided inside the machine frame 3 fixed on the chassis 2 and the machine frame 4 which is to be rotated outward with respect to the machine frame 3. 1, the side wall of the bale chamber 1 provided in one machine frame 3 is made into a movable side wall 5 that can be moved in and out, and an intervention member 7 is provided protruding from the other machine frame 4, so that both machine frames 3, The bale chamber structure of the roll baler is constructed such that an intervention member 7 moves the movable side wall 5 inward to a position flush with the adjacent side wall 29 and holds it in a state where the movable side walls 5 and 4 are overlapped.

(Operation of the invention) The collected items are compressed and packaged into a roll-shaped bale while being rotated in the bale chamber 1 that is formed inside the machine frames 3 and 4 which are stacked on top of each other. Since the intervention member 7 moves and holds the movable side wall 5 in a position flush with the adjacent side wall 29, the rotation of the collection is smooth and a good bale is formed.

Also, rotate one machine frame 4 outward to open the bale chamber 1.
When the bale is opened, the intervention member 7 is disengaged from the movable side wall 5, and the movable side wall 5 is moved outward by the lateral pressure of the bale, making it easier to take out the bale.

(Effects of the invention) As mentioned above, the collected items are compressed and packed well in the bale chamber 1, and when the bale chamber 1 is opened, the movable side wall 5
moves outward, facilitating removal of the shaped bale.

Since such movement of the movable side wall 5 in and out is performed by fitting and removing the intervention member 7 protruding from one machine frame 4 into the other machine frame 3, the structure is simple.

(Example) Next, an example of the present invention will be described with reference to the drawings.

At the front of the chassis 2 equipped with a traveling device 9 consisting of a crawler 8, there is a fixed machine frame 3 fixed on the chassis 2.
and a movable machine frame 4 which is pivoted at the front 10 to the fixed machine frame 3 and can be rotated upward at the rear to open the internal bail chamber 1. At the rear of the motor vehicle 2, a driving unit 13 on which a motor 12 is mounted is provided.

At the lower front of the fixed machine frame 3, there are a plurality of scraping rods 15 that protrude from the cylindrical body 14 at regular intervals in the lateral direction.
A pick-up device 16 is provided which rotates forward and upward as the cylindrical body 14 rotates to pick up collected items on the ground.

From the rear of the pick-up device 16 to the rear of the bale chamber 1, main endless chains 17, 17 are stretched close to the left and right side walls of the fixing machine frame 3, and a large number of transport rods 18 are attached to the main endless chains 17, 17. A carry-in device 19 is constituted by horizontally stacking them at regular intervals. This main endless chain 17, 17 is
Inside the bale chamber 1, it moves in an arc shape along curved chain rails 20 provided on the left and right sides of the fixing machine frame 3.

Furthermore, the bale chamber 1 is opened from the front end of this loading device 19.
Below the inlet 21 of the main endless chain 17, 17, the sub endless chain 22,
22 is stretched over the side of the fixed machine frame 3, and each of the sub endless chains 22, 22 is provided with a scraping bar 2 having a scraping claw that projects upwardly from the transport bar 18.
3 are placed horizontally within the spacing between the respective transport rods 18 to ensure that the collected material picked up by the pick-up device 16 is sent into the bale chamber 1.

A semicircular plate-like body 24 around which the chain rail 20 is fixed is fixed to the left and right sides of the fixed machine frame 3,
The side wall 5 is fitted into this semi-circular plate-shaped body 24 so as to be movable inwardly and outwardly and biased inwardly.

An intervention member 7 fixed to the movable machine frame 4, which will be described later, intervenes in the upwardly opening opening 25 of the semicircular dish-shaped body 24, thereby preventing the side wall 5 from moving outward. A spacer section 6 is provided to prevent this.

Inside the movable machine frame 4 constituting the upper part of the bale chamber 1, endless chains 26, 26 are stretched across the left and right sides of the bale chamber 1, and the conveyor rod 18 is attached to the endless chains 26, 26. A bundling conveyance device 28 is constructed by horizontally suspending a large number of conveyor rods 27 similar to the above at regular intervals. The bale chamber 1 side of the endless chains 26, 26 moves in an arc along a chain rail 30 fixed to the outer periphery of side walls 29, 29 fixed to the fixed machine frame 3.

Further, the fixed machine frame 3 is provided on the lower surface of the side wall 28.
A wedge-shaped intervention member 7 is provided to protrude between the sides 6.

A pivot shaft 10 that pivotally connects the movable machine frame 4 to the fixed machine frame 3
also serves as a mounting shaft for a drive sprocket provided on the front side of the bundling conveyance device 28.

A twine supply device (not shown) is provided on the rear outer side of the gap S formed between the rear end of the conveying device 19 and the rear end of the bundling conveying device 28 in the bale chamber 1. The twine is wrapped around the veil that has been compressed and formed.

Next, the state of use in this embodiment will be explained.

While traveling by driving the traveling device 9, the collected items are picked up onto the conveying device 19 by the lifting rod 15 of the picking up device 16. The collected items that have entered the bale chamber 1 on the transport device 19 are transported to the transport device 19.
While being rotated by the bundling conveying device 28, the diameter of the bale increases gradually, and the bale is formed into a bale of a constant diameter.

When the bale forming is completed, the running is stopped, and the twine is supplied into the bale chamber 1 from the spacer S and wound around the outer circumference of the bale. Thereafter, the movable machine frame 4 is rotated upward to open the bale chamber 1 and the bale is taken out of the machine. At the same time as the side wall 5 on the fixed machine frame 3 side is opened, the intervention member 7 is removed from the intervening part 6. The bale escapes and escapes outward due to the lateral pressure of the bale, making it easier to pull the bale upward.

In this embodiment, the rear part of the movable frame 4 is rotated upward to take out the bale from the rear upper part of the bale chamber 1, but the front part of the movable frame 4 is rotated upward to remove the bale. may be taken out forward from the introduction port 21 side.
