Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in a pick-up device for a baler.

A baler is a roll baler that forms bales into rolls.As shown in FIG. Pickup device a for picking up culms or grasses
and a bale chamber b for receiving the straw culms and grasses picked up by the bale chamber b, and a winding device c for rolling the straw culms and grasses received into the bale chamber b into a roll bale. By operating the pick-up device a and the winding device c while the machine body 1 is traveling, straw culms and grasses are picked up one after another from the field and rolled into bundles, When the bundle grows and is compressed to a predetermined pressure, the machine 1 stops traveling, opens the bale chamber b, and is used to take out the formed bale (bundle) from the machine. Ru.

In this way, the pick-up device a installed in the machine body 1 of the baler A that collects grass and straw culms and forms them into bales has a guide plate 20 formed in the shape of a narrow strip, as seen from the side. As shown in Figure 1, it forms a long shelf in the front and rear direction, protrudes forward, curves downward in an arc, and returns to the rear.The front end is arc-shaped and the rear end is shelf-like, facing vertically. A large number of guide plates 20 are arranged in parallel in the left and right direction with a small gap d as shown in FIG. By connecting them together, a pick-up drum 2 is formed, which is fixed to the fuselage 1 or supported in a vertically movable manner, and the inner cavity of the pick-up drum 2 has a hole that penetrates left and right at the axial center position of an arc-shaped portion on the front end side. A rotary shaft 30 is arranged and rotatably supported, and tines 31 protruding radially are provided at portions of the rotary shaft 30 corresponding to the respective intervals d of the guide plates 20 described above. , the tines 31... are rotated while appearing and retracting from each gap d of the guide plates 20... by the drive rotation of the rotating shaft 30, and the pick-up drum 2
As shown in FIG. 1 when viewed from the side, side plates 4, 4 projecting forward and upward from the circumferential surface of the pick-up drum 2 are provided at both left and right end portions of the tine 31. The structure is such that grass and straw culms are scooped up from the field to the upper surface of the pick-up drum 2 by the rotation of the pick-up drum 2.

By the way, the pick-up device a of the baler A configured as described above usually has left and right side plates 4, 4 installed at both left and right ends of the pick-up drum 2, as shown in FIG. , are fixedly attached to both ends of the pick-up drum 2 so as to face forward and widen the left and right facing distance. This was developed so that the baler A can form bales of grass that has been cut down in the field and dried on the ground. This is because it is adapted to pick up grass windrows that are collected in the grass. That is, if the left and right side plates 4, 4 are installed so that their respective front ends expand outward, even if the pick-up device a is slightly deviated to the left or right with respect to the windrow, the left and right side plates 4, Now that the window row is located within the interval 4,
This is because the work becomes easier as the aircraft 1 becomes easier to maneuver. However, the pick-up device a configured in this way is used to pick up rice and wheat that are left in a field after harvesting with a combine harvester, with the direction of the culm perpendicular to the direction of movement of the machine 1. When picking up straw culms to form them into bales, the long straw culms that are picked up by the tines 31 are gradually compressed from the left and right by the left and right side plates 4, the width of which is gradually narrowed. This causes problems such as clogging and making the straw culm unsuitable for picking up long straw culms. When picking up such a long straw culm, the left and right side plates 4, 4 are attached to the pick-up drum 2 in a position along the direction of movement of the machine body 1, as shown in Fig. 4. Then, when the straw culm is raked in with the tines 31..., both ends of the straw culm come into contact with the front edges of the side plates 4, 4 at right angles, so that the straw culm is forcibly bent from the contact point. However, it has been found that pick-up can be carried out smoothly.

Therefore, in the present invention, the pick-up device a
The purpose is to make it possible to easily switch between a state adapted to picking up a windrow and a state adapted to picking up a long straw culm, so that these operations can be performed in a state adapted to each. , left and right side plates 4, 4, which were conventionally fixedly provided to the pick-up drum 2.
, the attitude where their front end side expands outward and the aircraft 1
The present invention provides a pick-up device which can be freely switched between a posture substantially parallel to the direction of movement of the pickup device.

Next, an example of implementation will be described in detail with reference to the drawings. In addition,
The same reference numerals in the drawings as in the conventional means are used for components having the same effect.

FIG. 5 is a perspective view of the entire roll baler A in which the present invention can be implemented, and 1 indicates left and right traveling devices 10, 10.
A is a pick-up device mounted on the front end of the machine (one of which is not clearly shown in the drawing), and b is a bale that forms the workpiece picked up by the pick-up device a into a bundle. 5 is the running device 10,

It shows the machine casing that houses the prime mover and control device that drive the winding device c inside.

The pick-up device a includes a pick-up drum 2, which has a large number of narrow band-like guide plates 20 arranged in parallel on the left and right with a small interval d, and an axis of an arc-shaped portion on the front end side of the pick-up drum 2. A rotating shaft 30 provided to pass through the part from side to side, and the rotating shaft 30
The distance d between a large number of parallel guide plates 20 of the pick-up drum 2 that are radially provided on the circumferential surface of the pick-up drum 2.
It is the same as before in that it is composed of tines 31 that rotate while appearing and retracting from... and left and right side plates 4, 4 provided at both left and right ends of the pick-up drum 2,
At the upper end side of the front edge 4a of the left and right side plates 4, 4, which form a semicircular arc shape when viewed from the side, a stepped portion w extending in a substantially vertical direction is formed above the upper peripheral surface of the pickup drum 2. The side plate 4 extends along the upper end of the stepped portion w in the front-rear direction.
The front end of the upper edge 4b is continuous (Fig. 6).

And also, these left and right side plates 4, 4
In the conventional means, it was fixed to both the left and right ends of the pick-up drum 2 or to the machine frame integrally connected to the pick-up drum 2 so as not to move.

A connecting tool 40 is provided at a portion to be joined to the peripheral surface of the
By connecting the connecting tools 40 to the mounting seats 60 provided on the circumferential surface of the pick-up drum 2 via the set bolts 61, it can be assembled to the pick-up drum 2, and it can also be attached to the circumferential surface of the pick-up drum 2. By arranging a plurality of the assembly seats 60 in parallel in the left and right direction as shown in FIG. 7, selecting one of these assembly seats 60, and connecting and setting the connecting tool 40, As shown in the state shown by the solid line and the state shown by the chain line in FIG. 7, the left and right side plates 4, 4 are arranged so that the width of the left and right spacing on the front end thereof can be changed and adjusted. This adjustment is performed with the left and right side plates 4, 4 installed in an attitude substantially parallel to the traveling direction of the aircraft 1, which is shown by the solid line in Fig. 7, and as shown by the chain line in Fig. 7. It is only necessary that the connecting device 40 provided on the side plates 4, 4 can be switched to a state in which it is mounted in an outwardly expanding position that deviates outward toward the front end. In the case where the mounting seat 60 is provided on the circumferential surface of the pick-up drum 2, the mounting seat 60 corresponding to the connector 40 on the rear end side can be loosened by loosening the set bolt 61. 61, the front end side of the side plate 4 is formed so as to be rotatable left and right, and the assembly seat 60 corresponds to the connector 40 on the front end side.
It is sufficient to arrange them on a virtual arc centered on the assembly seat 60 and to arrange them in parallel in two rows. However, when the assembly seats 60 corresponding to the connectors 40 on the front end side are arranged in parallel on the virtual arc and installed in an outwardly expanding position as shown by the chain line in FIG. The outward inclination angle of the can be selected as desired.

The thus constructed embodiment apparatus operates as follows.

When collecting straw culms S left in the field in a position perpendicular to the direction of movement of the machine body 1 as shown in Figure 4 and forming them into bales, the left and right side The work is carried out by assembling the plates 4, 4 to both ends of the pick-up drum 2 in a posture parallel to the traveling direction of the machine body 1, as shown by solid lines in FIG.

As a result, the straw culms scraped by the tines 31 have both ends connected to the left and right side plates 4,
4, and is scratched by the tines 31 in that state, so that the side plate 4 is bent from the point where it abuts on the front edges 4a, 4a of the side plates 4, 4. , 4, or rises along the leading edges 4a, 4a to form the step w.
When the straw is received by the vertical front edge of the drum, it is bent from the point where it comes into contact with the vertical front edge of the straw and is pushed onto the upper circumferential surface of the pick-up drum 2 between the side plates 4, 4. The culm can now be picked up without getting stuck between the left and right side plates 4, 4 (Fig. 4).

In addition, when picking up grass windrows that have been cut down and collected in rows in the field, the left and right side plates 4, 4 should be connected to the connector 4.
0... and the assembly seats 60..., switch to the state shown by the chain line in FIG. 7, and install them, and work in that state.

As a result, even if the pick-up device a provided on the aircraft body 1 is slightly deviated to the left or right with respect to the windrow, the windrow that is picked up by the rotating tines 31 will reach the inner wall surfaces of the left and right side plates 4, 4. By being guided and scraped into the upper peripheral surface of the pick-up drum 2, the work can be done easily.

As explained above, the pick-up device for a baler according to the present invention has the left and right side plates provided at both the left and right ends of the pick-up drum in a posture in which their front ends are expanded outward in a plan view, and in the direction of movement of the machine body. Since it is installed so that the left and right side plates can be switched to a substantially parallel position, by assembling the left and right side plates in a position where the front end side expands outward, the grass that is being cut down in the field can be easily adjusted. Windrow pick-up work can now be carried out easily, and by switching this side plate to a position that is approximately parallel to the direction of movement of the machine, the field can be cut down in a position perpendicular to the direction of movement of the machine. The work of picking up long straw culms, which is currently being used, can now be carried out smoothly without causing blockages.

Therefore, according to the means of the present invention, it is possible to carry out two operations, the windrow pick-up operation and the long straw culm pick-up operation, by changing the state to suit each of these operations.
