Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvester for transporting crops.

[0002]

2. Description of the Related Art In a conventional harvester, a chassis on which a container for storing a conveyed harvested product is mounted is integrally formed with a chassis supporting a transmission case, an operation seat, and the like. It was not a configuration.

[0003]

In the harvester as described above, the container is inevitably large in size because the container has a considerably large size for storing a large amount of harvested material. Then, when welding and painting the chassis, there is a disadvantage that the equipment becomes large and assembly becomes difficult. Further, when transporting the harvester, there is a disadvantage that it is difficult to get on a truck or the like.

[0004] It is an object of the present invention to provide a harvester which overcomes the above-mentioned problems.

[0005]

The above object of the present invention is achieved by the following constitution. That is, in a harvesting machine provided with a transport device 3 for placing and transporting the harvested material to one side of the undercarriage 2 having the traveling device 1, the undercarriage 2 is transported to the terminal end of the transport device 3. A harvester characterized by connecting and providing a second chassis 5 on which a container 4 for storing harvested products is placed.

[0006]

Embodiments of the present invention will be described with reference to the drawings. FIGS. 1 to 6 show a harvester A embodying the present invention.
It is shown. This embodiment shows a harvester A taking root vegetables, particularly radish as an example. A transport device 3 for transporting radish 6 harvested from a field in the direction of the chassis 2 is provided on one side of the front of the chassis 2 having the traveling device 1 (on the left side in the traveling direction in the present embodiment, but on the right side). And a container 4 for storing the radish conveyed to the terminal end of the conveying device 3 is placed on the chassis 2. The transport device 3 is provided with a cutter 8 for cutting the foliage 6a of the radish being transported, and an operating unit 9 for operating the harvester A is provided on the front right side of the chassis 2.

FIG. 3 is a diagram of the transmission mechanism of the radish harvester A described above. The power of the engine 10 is the transmission 1
The power input to the transmission 11 is arbitrarily shifted by a hydraulic stepless transmission including a variable hydraulic pump 12 and a constant-pressure hydraulic motor 13 to drive the traveling device 1 and to partially drive the power. Power is hydraulic pump 14
To drive the hydraulic motor 15. The power transmitted to the hydraulic motor 15 is transferred by the belt 16 to the transport device 3.
The shaft 17 at the end of the conveying direction is driven, and power is transmitted by a plurality of chains to drive the shaft 18 at the starting end of the conveying device 3 in the conveying direction. Further, a part of the power for driving the transport device 3 is configured to drive the cutter 8 that cuts the foliage 6a of the radish.

When the harvesting operation is started by running the harvester A, a plurality of workers 19 on the side of the undercarriage 2 pull out the radish from the field scene and place it on the transport device 3.
Then, the radish is conveyed toward the container 4 on the undercarriage 2 side, and the foliage 6a of the radish 6 is cut by the cutter 8 on the way. After that, the radish conveyed to the terminal end of the conveying device 3 is stored in the container 4 by the assistant 20. The harvester A runs at an arbitrary speed while performing such operations.

The second chassis 5 on which the container 4 is placed
Is configured to be independent from the chassis 2 on which the transmission 11 and the operation unit 9 are mounted, and the container 4 is mounted on the second chassis 5. For this reason, the second chassis 5 is detachably fixed to the chassis 2. 4 to 6 show the configurations of the chassis 2 and the second chassis 5.

FIG. 4A is a rear view of the chassis 2, and FIG.
(B) is a plan view thereof. FIG. 5A is a rear view of the second chassis 5, and FIG. 5B is a plan view thereof. FIG. 6 (a)
FIG. 6 is a rear view in which the chassis 2 and the second chassis 5 are combined, and FIG.
(B) is a plan view thereof. The second chassis 5 is configured by a frame, and the frames 5a and 5b extending in the front-rear direction of the harvester are mounted on the frames 2a and 2b that configure a part of the chassis 2 respectively. Further, a frame 5c orthogonal to the frames 5a, 5b of the second chassis 5 is placed on a frame 2c orthogonal to the frames 2a, 2b of the chassis 2, and this state is a normal installation state.

In this state, the chassis 2 and the second chassis 5 are fixed. As shown in FIG. 7, the fixing method in this configuration encloses the frame 2a and the frame 5a, and the frame 2b and the frame 5b with a U-shaped plate 21, and the U-shaped plate 21 and the frame 2a, 5a and the U-shaped plate 21 and the frames 2b and 5b are fixed with bolts. Fixing is performed at multiple locations.

As described above, since the second chassis 5 on which the container 4 is placed is made independent of the chassis 2, the following effects are produced. First, at the time of production at a factory, the size of the chassis 2 is reduced, so that the fixing jig during welding is reduced. Secondly, when the chassis 2 is painted, the chassis 2 is made compact, which facilitates painting.

Third, the size of the second chassis 5 attached to the chassis 2 can be changed. In other words, although there is a limit, if it is desired to increase the number of containers 4, the second chassis 5
Can be selected and attached to the chassis 2. Fourth, the second undercarriage 5 can be mounted not only with containers but also with a dedicated second undercarriage on which another working machine, for example, a fertilizer or a sprinkler, is mounted.

Next, FIG. 8 will be described. FIG. 8 (a)
Fig. 3 is a view of the transport device 3 of the harvester A as viewed from the front. The transporting device 3 is divided into two parts, the first transporting device 3a at the start end in the transporting direction and the second transporting device 3b at the terminal end.
The first transport device 3a and the second transport device 3b are both supported by the damper 22.

The lifting and lowering of the first transfer device 3a is performed by a hydraulic cylinder 24. The base of the hydraulic cylinder 24 is supported by a column 26 having a rotation fulcrum 25 where the transfer device 3 moves up and down. The lifting and lowering of the second transfer device 3b is performed by the hydraulic cylinder 2
3 and the base of the hydraulic cylinder 23 is also supported by the column 26. Such a configuration is a normal use state.

Since the configuration is as described above, FIG.
As shown in (b), when an arbitrary position of the transport device 3 is gripped and lifted upward by human power, the damper 22 is extended, and the transport device 3 is configured to easily lift upward together with the hydraulic cylinders 23 and 24. At this time, of course, the hydraulic cylinders 23, 24
It is necessary to lengthen the piping that sends oil to the tank in anticipation of that amount. Thereafter, when the gripping of the transport device 3 is released, the configuration returns to the normal use state described with reference to FIG.

Therefore, if the transport device 3 is likely to come into contact with an obstacle, the transport device 3 can be instantaneously lifted up manually to avoid the obstacle without operating the levers of the operation unit 9 of the chassis 2. Can be. Next, FIG. 9 will be described. The traveling device 1 on the side of the transport device 3 while the harvester A is traveling.
When the carrier falls into the ridge groove 28, the transporting device 3 falls down, and the transporting device 3 hits the foliage 6a of the radish 6, and in the worst case, a problem occurs in which the foliage 6a is involved.

Therefore, the contact type sensor 27 is
When the contact sensor 27 detects an obstacle (in this case, most of the foliage 6a of the radish 6), this signal is input to a CPU (not shown),
Transmits a signal to an electromagnetic valve (not shown) of a hydraulic cylinder 29 that moves up and down the transport device 3,
And the transport device 3 is raised. The installation position of the contact type sensor 27 should be
Is better on the starting end side in the transport direction.

Next, FIG. 10 will be described. The contact-type sensor 27 described in FIG. 9 is limited to only a part of the transport device 3 on the starting end side in the transport direction. In FIG. 10, the transport device 3 is moved to the first transport device 3 on the start end side in the transport direction.
a and the second transporting device 3b on the terminal side, the contact type sensor 27 is provided over substantially the entire section in the transporting longitudinal direction of the first transporting device 3a.

With this arrangement, if the foliage 6a of the radish 6 comes into contact with any part of the first transfer device 3a, the hydraulic cylinder is extended and the first transfer device 3a is raised. Therefore, the foliage portion 6a of the radish 6 is more reliably added to the first transport device 3a.
Can be prevented from being involved. In FIG. 10, since the transport device 3 is divided into the first transport device 3a and the second transport device 3b, the first transport device 3a can be horizontal with respect to the field scene 30. Also, the height of the first transport device 3a from the field scene 30 can be arbitrarily set by adjusting the elevation of the second transport device 3b, so that the height can be set to a desired position according to the height of the worker.

[0021]

According to the present invention, as described above, the second undercarriage 5 on which the container 4 for storing the harvested product conveyed to the terminal end of the conveying device 3 is formed separately from the undercarriage 2, 2
In this case, the second chassis 5 is connected, so that the chassis 2 is reduced during production at the factory, so that the fixing jig for welding is reduced, and when the chassis 2 is painted. Since the chassis 2 is made compact,
Painting is easier.

Further, the size of the second chassis 5 connected to the chassis 2 can be changed. In other words, there is a limit, but container 4
When it is desired to increase the number of vehicles, it is possible to select the second undercarriage 5 conforming to the number and connect it to the undercarriage 2. Further, the second chassis 5 can be mounted with another working machine, for example, a dedicated working machine on which a fertilizer applicator, a sprinkler, or the like is mounted, irrespective of only mounting the container.
