Description

[Detailed description of the invention] "Industrial application field" The invention is based on a plurality of pick-ups that rotatably support straw grass such as grass and straw scattered in a field on a finger body via an eccentric shaft. This invention relates to a roll baler that picks up bales with fingers and forms them into roll-shaped bales in a bale forming chamber.

``Prior Art'' Conventionally, as shown in Japanese Utility Model Publication No. 55-38359, there has been a technique for picking up straw by providing a plurality of pick-up fingers.

"Problems to be Solved by the Invention" In the prior art, when a finger guide member is provided in the opening of the finger body through which the tip side of the pick-up finger enters and exits, a finger guide member is provided for each pick-up finger. There are problems in that it is troublesome to attach the guide member, and when the finger guide member becomes worn, it is necessary to immediately replace it with a new one.

``Means for Solving the Problems'' However, in the present invention, an eccentric shaft is installed inside the finger cylinder, the base ends of a plurality of pick-up fingers are connected to the eccentric shaft, and the tips of the pick-up fingers are placed on the outer peripheral surface of the finger cylinder. In a roll baler that picks up straw by moving it in and out, a finger guide member is provided with a plurality of openings through which the tips of a plurality of pick-up fingers are inserted, and the plurality of finger guide members are connected alternately from front to back and are fixed to the finger body. It is characterized by the fact that

``Operation'' Therefore, since a plurality of pick-up fingers are guided in and out by the same finger guide member, the mounting structure of the finger guide member is simpler than a structure in which a finger guide member is provided for each pick-up finger separately. In addition to being able to properly guide the pick-up finger,
Since a plurality of finger guide members are arranged alternately on the front and back, it is possible to easily fix the finger guide members using the overlapping portion, and the mounting direction of the finger guide members can be changed to the front and back or to either the left or right direction. Accordingly, even if the opening of the finger guide member is deformed due to wear, the finger guide member can be reused by changing the opening portion that the pick-up finger touches to a position other than the worn portion, and the handling of the finger guide member can be improved. It is possible to easily improve operability and durability.

In addition, 49 in the figure is integrally fixed to the pick-up side plate 29 and covers the front side and upper part of the conveyance side of the lower pipe conveyor 19, and the lower endless chain 3
Chain cover to prevent straw from adhering to 7.
50 is laid between the pick-up side plates 29 via the brackets 30 and 31 below the conveyance side of the lower pipe conveyor 19 to integrally connect the left and right pick-up side plates 29 and to prevent the bale forming lower pipe 38 from curving. The reinforcing plate 51 is a baler cover that covers the left and right rear sides of the bale forming chamber 17.

Furthermore, the left and right pick-up side plates 29
One end of a turnbuckle 52 is rotatably supported, and a wire 53 is connected to the other end.

As shown in FIGS. 6 and 7, an adjustment bolt 55 is rotatably supported by a pick-up elevating case 54, one end of which is integrally fixed to the left side of the rear surface 51a of the baler cover 51. The lifting lever 13 is removably fitted, and a nut member 56 connecting the wires 53 on the left and right sides is screwed on, and a sliding needle 57 is integrally fixed to one side of the nut member 56, and its tip is guided. facing the outside of the case 54 through the hole 58,
When the adjustment bolt 55 is rotated by the rotation of the pick-up elevating lever 13, the nut member 56 is moved back and forth, the wire 53 is pulled or loosened, and the pick-up side plate 29 is moved around the fulcrum shaft 28 via the turnbuckle 52. The pick-up section 4 is configured to swing up and down at the center and adjust the height of the pickup section 4 above the ground as appropriate by operating a wire.

As shown in FIGS. 1 and 8, a plurality of the pick-up fingers 40 are arranged in the left and right directions of the finger body 41, and a set of four pick-up fingers 40 are arranged on the eccentric shaft 39 via a metal 59. A plurality of sets of fingers 40 are installed at equal intervals. In addition, each opening 61 is formed in the grommet 60, which is a finger guide member that protrudes and guides each set of four fingers 40 radially, and two different angles α and β, large and small, are formed on the circumference of the finger body 41 with the support shaft 32 as the center. The grommets 60 are provided on the outer surface of the finger body so that the grommets 60 are arranged alternately, and the pitches of the openings 61 on the circumference of the finger body 41 are alternately varied in size,
When the finger body 41 rotates, the finger 40 protrudes to the maximum and picks up straw at the lower front part of the pick-up part 4 where the circumferential speed is maximum.

Furthermore, four openings 61 of one grommet 60
and four fingers 40 protruding in the same direction.
are collectively projected and guided to the outside of the finger cylinder 41 by one grommet 60, and a plurality of grommets 60 are connected and fixed in the left and right lateral directions of the finger cylinder 41.

As shown in FIG. 9, the grommet 60 has four
A guide part 62 that opens two openings 61, and a mounting piece 63 that is connected to the finger body 41 on the outer periphery of the guide part 62.
are integrally formed, and the thickness t of the mounting piece 63 is
The lower part of the guide portion 62 is formed to protrude from the mounting piece 63 by an amount equal to (i.e., t=l), and 2 of the amount of protrusion is formed.
The upper part of the double guide part 62 is formed to protrude from the mounting piece 63 (i.e.
2l) When a plurality of the grommets 60 are arranged and fixed in a row in the left and right lateral directions of the finger cylinder 41, the grommets 60 are arranged in a row alternately on the front and back, and the ends of the adjacent mounting pieces 63 are overlapped. The ends are integrally fixed to the finger body 41 with screws 64, and each grommet 60 is formed so that the upper surface of the grommet 60, that is, the upper surface of the guide section 62 is even with the upper surface of the adjacent guide section 62.

The pick-up finger 40 is formed of an elastic material, and has a hook portion 40a formed at its base end, so that the finger 40 is attached to the eccentric shaft 39 so as to be freely hookable and detachable.

This embodiment is constructed as described above, and the hay picked up by the pick-up section 4 is transferred to the bale forming chamber 17 by the lower pipe conveyor 19.
The bales A are carried into the forming chamber 17 and formed into roll-shaped bales A by the rotating action of the upper and lower pipe conveyors 18 and 19. After the bales A are tied by the bundling device 14, the door 15 is opened. The left side of the bale forming chamber 17 is opened and the bale A is taken out of the machine using the pull-out lever 16.

Furthermore, when picking up straw grass, finger 40
is constantly protruding into and out of the finger body 41, and therefore, as shown in FIG. 10, the finger 4
However, since the grommets 60 are formed so that they can be installed in reverse, the sliding contact portions of the finger 40 and the grommet 60 will slide at positions opposite to the above. The grommet 62, which is a consumable part, can be used for twice as long, and the number of times it must be attached and detached can be halved.

Furthermore, the grommet 60 is attached to the finger body 4.
1, the mounting pieces 63 of adjacent grommets 60 can be overlapped and one side of the two grommets 60 can be connected and fixed with a single screw 64.
By drastically reducing the number of screw fixing locations, and by guiding the four fingers 40 at once with one grommet 60, the number of grommets 60 can be reduced, making it easier to attach and remove grommet 60, which was previously a time-consuming task. This makes it extremely easy and quick to do so.
