Description

[Detailed description of the invention] Industrial application field This invention relates to a roll baler that collects grass, waste straw, etc. and forms it into a roll.

Prior Art In this type of roll baler, the bale forming chamber is constructed by a pipe conveyor constructed from a plurality of pipes installed between chains on both sides.
There are the ones described in Japanese Patent No. 15829, and the one described in West German Patent No. 2443838, in which a bale forming chamber is constituted by rolls mounted on both side walls.

Problems that the invention aims to solve When configuring a pipe conveyor to bundle collected items, the collected items are forcibly transported, so the collected items can be bundled and transported reliably, but on the other hand, because the pipe conveyor revolves, If the bale is sensitive to overload and cannot be formed into a hard bale, and if the collection is configured to be bundled with multiple drive rolls mounted between side walls, the drive rolls must be firmly held and forced. Since it rotates, it is possible to form a relatively hard bale, but since the collected material is rotated only by the frictional force of the drive roll, it may be slippery and cannot be formed into a roll shape.

Additionally, anti-slip protrusions are provided on the outer periphery of this drive roll to increase the frictional force with the bale, but if these anti-slip protrusions are made extremely long, the collected material will be caught and wound around the drive roll. It may damage the drive parts.

This invention is intended to effectively utilize the features of each of the bale forming apparatuses described above to reliably bundle and transport collected items without causing slippage, and further to form a hard bale.

Means for Solving the Problem A bale forming chamber 3 for forming rolled bales, etc., collected and brought in by a pick-up device 1 and a carry-in device 2 connected to the rear of the pick-up device 1 is located at least in the lower part. A pipe conveyor 6 consisting of pipes 5, 5 installed at predetermined intervals between a pair of chains 4, 4 disposed on both sides, and side walls 7, which are located in the upper part of the bale forming chamber 3 and can be driven and rotated. The roll baler is constituted by a plurality of rolls 8, 8 which are mounted on a shaft.

Effect of the invention Collection by the pick-up device 1 and carrying-in device 2
The collected materials brought into the bale forming room 3 by
The bales are bundled and transported rearward by a pipe conveyor 6 located in the lower part of the bale forming chamber 3, and then sequentially bundled and transported by a plurality of rolls 8, 8 located in the upper part to be formed into rolled bales.

During this bale forming, the collected material is reliably bundled and conveyed by the pipe conveyor 6 in the lower part, and the revolving range of the pipe conveyor 6 is configured to be shorter than the entire circumference of the bale forming chamber 3, so that the revolving load is reduced. It is smoothly driven in revolution.

Subsequently, the collected material is friction-driven by a plurality of rolls 8, 8, and bundled and transported, but the collected material has already been given rotational force by the pipe conveyor 6, and is easily transferred by the rolls 8, 8. The pipe conveyor 6 is reliably bundled and transported and the load is reduced, and the rolls 8, 8 are firmly supported on both side walls 7, 7.
It can be formed into a hard bale by

Effects of the invention Since this invention is constructed as described above, the collected material carried into the bale forming chamber 3 is reliably bundled and conveyed by the pipe conveyor 6 located in the lower part, and further The collected materials are transferred by the friction force of the rolls 8, 8 in the upper part, so that the collected materials are rotated reliably without slipping, and the collected materials are rotated from the entire circumference of the bale forming chamber 3. The bale can be formed into a hard bale by using the pipe conveyor 6 which has a short structure and reduces the revolving load, and the rolls 8, 8 which are firmly mounted on both side walls 7, 7.

Embodiment In the embodiment shown in the figure, the roll baler is mounted on a crawler-type traveling device 9 and a machine base 10.
Laterally located prime mover and control device (not shown)
It is configured to be able to run.

A pick-up device 1 for collecting grass, etc. scattered in fields, etc. is installed in front of the machine 10, and a carry-in device 2 and a pipe conveyor 6 located in the lower part of the bale forming chamber 3 are installed behind the pick-up device 1. It is constructed in a continuous manner.

The carry-in device 2 and the pipe conveyor 6 are constructed in the shape of a conveyor by pipes 5, 5 installed at predetermined intervals between a pair of chains 4, 4 located on both sides.
The collected materials are carried into the bale forming chamber 3 and are bundled and transported in the lower part of the bale forming chamber 3. 11 and 12 are drive guide wheels of the chains 4 and 4.

Reference numeral 13 is a scraping device, in which pipes 1 are installed at predetermined intervals between the chains 14, 14 located on both sides.
5, 15, a scraping plate 16 whose upper end is formed with a rough surface;
16 is attached, and the scraping plate 16 is positioned between the pipes 5, 5 of the carrying-in device 2. 17,1
8 is a drive guide sprocket for the chain 14.

Further, in the rear and upper portions of the bale forming chamber 3, rolls 8, 8 are disposed along the outer periphery of the bale forming chamber 3, and are attached to a shaft 19 installed between both side walls 7, 7. Note that the surface of this roll 8 may be formed into a rough surface for anti-slip purposes.

Both side walls 20, 20 on which the carry-in device 2 and the pipe conveyor 6 are mounted are configured to be slightly wider than the width of the bale forming chamber 3, and are arranged inwardly at a position slightly above the conveyance surface of the carry-in device 2 and the pipe conveyor 6. Chains 4, 4 of the folding and carrying device 2 and the pipe conveyor 6
A bent portion 21 is formed to cover the mounting portions of the pipes 5 and 5.

On the bent portion 21, the lower bent portions 22, 22 of both side walls 7, 7, which support the rolls 8, 8, are removably superimposed, and the interval between the both side walls 7, 7 is formed by bale forming. It is configured to have the same width as the width of the chamber 3, and the bent part 2
1, 22 Above the drive sprocket 23 of the roll 8
A transmission device such as the following is located. Note that 24 indicates a mating surface between the upper and lower bent portions 21 and 22.

Further, reference numeral 25 indicates a dividing surface between the side walls 7, 7, and the upper swinging frame 26 is configured to be able to be opened and closed on the dividing surface 25 about a hinge 27. 28 is the swing frame 2
6 is an opening/closing handle, and 29 is a guide plate for discharging the bale. Reference numerals 30, 30 denote side plates of the bale forming chamber 3, which are formed in a semicircular shape and are held by the upper swing frame 26 and the lower side walls 7, 7.

Collected by pick-up device 1 and carried in device 2
The collected materials carried into the bale forming chamber 3 by the scraping device 13 are located in the lower part of the bale forming chamber 3, and are bundled and conveyed rearward by the pipe conveyor 6 integrated with the carrying device 2. multiple rolls 8,
8 and are sequentially bundled and transported to form a rolled bale.

During this bale formation, in the lower part of the bale forming chamber 3, the revolving pipe conveyor 6
The collected items are reliably bundled and transported by the rollers 8 and 8, and the collected items that have been transported and subjected to rotational force are reliably bundled and transported by the upper rolls 8, 8 without slipping. The pipe conveyor 6 is configured to be shorter than the entire circumference of the bale forming chamber 3 to reduce the revolving load, and the guiding rotation of the pipe conveyor 6 can be configured relatively firmly. The collected material is tightly bundled and conveyed by rolls 8, 8 held by the container to form a hard bale.

Furthermore, the attachment parts of the chains 4, 4 of the pipe conveyor 6 and the pipes 5, 5 are located outside the width of the bale forming chamber 3, so that the oil applied to the chains 4, 4 is less likely to adhere to the collected material. . When taking out the formed bale, operate the handle 28 to move the swinging frame 26
is rotated upward around the hinge 27 to open the bale forming chamber 3 and take it out to the rear.
