Description

[Detailed description of the invention] (Field of industrial application) This invention collects collected materials such as cut down grass and threshed straw that has been released onto the ground while driving, and compresses and packs them into rolled bales. Regarding roll balers.

(Prior art) As described in Japanese Utility Model Publication No. 62-39643, a roll baler is equipped with a raking device at the front of the machine in which a raking rod rotates from below to the front and upward to pick up the collected material. A conveying device in which a large number of rod-shaped conveying tools are horizontally arranged is installed in the section, and the collected material picked up by the scraping device is sent into the bale forming chamber by the conveying device.

(Problems to be Solved by the Invention) In order to reliably transport the collected items, the above-mentioned conveying device has a bar-shaped conveyor provided with a protrusion so that the collected items are hooked and sent. The amount of protrusion from the rod-shaped conveyor is low and the same throughout to improve the separation of collected materials in the bale forming chamber, so that the protrusions pass through the left and right machine walls, are conveyed, and are bent. There are cases where the feeding action of the collected material with large transport resistance is insufficient, and the collected material stagnates on the transport device.

(Means for Solving the Problem) Therefore, in the present invention, the raking rods 20 arranged laterally at appropriate intervals approach the raking device 13 which is to be rotated from below to the front and upper side, and In a roll baler raking conveyance device including a conveyance device 16 in which conveyance devices 30 and 31 arranged horizontally in a horizontal direction move from the front to the rear, left and right mechanisms provided on the conveyance device 31 of the conveyance device 16 are used. wall 4,4
The conveying protrusion 3 at the portion close to the conveying protrusion 3 is configured to protrude more than the conveying protrusion 2 at the central portion.

(Operations and effects of the invention) The collected material picked up by the scraping rod 20 of the scraping device 13 rides on the conveying tools 30 and 31 of the conveying device 16 and is sent into the bale forming chamber.
In the raking device 13, since the raking rods 20 on the outermost left and right sides also scrape up the collected material on the outside of the machine wall, the amount tends to be larger than that in the center part, and the collected material on the conveying device 16 is collected on the left and right machines. Since it is fed while sliding against the inside of the walls 4, 4, it causes resistance, but the scraping protrusion 3 with a large protrusion provided on the conveying tool 31 ensures that only the left and right sides, where this amount is large and the feeding resistance is large, are collected. Since the collected material does not stagnate on the conveying device 16 and is transported smoothly, most of the central protrusions 2 are low, so that the protrusions 2 and 3 of the collected material in the bale forming chamber are
It is also good to separate it from the

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

A scraping device 13 is provided in front of a machine base 12 equipped with a traveling device 11 consisting of a crawler 10, and a bale forming chamber 1 is formed inside a fixed machine frame 14 and a movable machine frame 15 mounted on the machine base 12. However, a conveying device 16 is provided between the bale forming chamber 1 and the scraping device 13. Further, on the side of the fixed machine frame 14 and the movable machine frame 15 on the machine stand 12, a driving frame 18 having a prime mover 17 mounted therein is provided.

In the raking device 13, a raking rod 20 that projects radially from each arrangement gap of a plurality of arcuate guide rings 19 arranged in the horizontal direction rotates from below to the front and upward, thereby raking up collected items on the ground. I did it like this,
A front cover plate, such as a rubber plate, whose upper part is covered with a scattering prevention plate 22 suspended horizontally on a side frame 21 erected on both left and right outer sides of the arcuate guide ring 19, and whose front side is suspended from the scattering prevention plate 22; 23, and at the corners of the front vertical edge 24 and the front lower side edge 25 of the left and right side plates 21,
