Description

[Detailed description of the invention] The present invention has a group of stem rod pulling devices that move the stem rod locking claws that protrude in the lateral direction of the aircraft body from near the ground to upwards. A stalk combing device that moves a locking claw upward from near the ground at a front location of the pulling device group is configured to be replaceable between a lateral end position and a lateral intermediate position of the pulling device group. Regarding the lifting device in a harvester, when changing the lower end of the stem combing device to a different position, it is necessary to assemble it so that it can be easily assembled to the desired state and separated. It is intended to provide strong support under certain conditions.

The above-mentioned lifting treatment device combs the stems planted in the field in advance using the stem stick combing device, thereby removing the fallen stems that are difficult to catch with the claws of the stem stick pulling device. This system is designed to be able to pull up the stem rods well, and moreover, by making the stem stick combing device switchable between the lateral end position and the lateral intermediate position of the group of lifting devices. Therefore, there is a state in which an effect is exerted to separate the entanglement between the group of stem rods to be reaped located at a portion corresponding to the front of the machine body and a group of uncut stem rods located on the lateral side of the machine body, and a state in which the group of stem rods to be reaped is separated. The device can be used depending on the working conditions to perform the action of accurately transferring the lifting device to the lifting device in the desired posture, thereby making it possible to perform even better lifting processing. , supporting the stem-rod combing device so that it can be moved to different positions;
The following problem occurred in supporting the lower end.

In other words, in the past, a means was adopted in which frames for supporting the combing device were provided at the lateral end positions and lateral intermediate positions of the pulling device group, and these frames and the lower end of the combing device were fixed using bolts. However, in this case, the operation of fixing the support frame, which will be located at the lowest position of the machine body, and the lower end of the combing device using bolts is performed by the worker in a bent position. This tends to be difficult and complicated work, making it difficult to perform the entire replacement work quickly and efficiently.

Incidentally, even if the upper end of the combing device uses a bolt fastening structure similar to the structure for the lower end described above, it is easy to perform the bolt fastening operation because it is located above the aircraft body. In addition, as will be described in the examples below, it can be supported in a form that can be easily replaced by using a structure in which the tip of the stalk to be harvested is slidably supported on a horizontal frame that is horizontally supported in a detour manner. Therefore, there are no particular problems.

The present invention has been developed with the above-mentioned circumstances in mind, and it is possible to easily assemble and separate the support structure of the lower end of the combing device into a desired state. The aim is to improve the structure so that it can be supported firmly in the assembled state.

Embodiments of the present invention will be described below based on the drawings.

Figure 1 shows the side view of the front part of the combine, including a device 1 for raising and processing stems planted in the field, a reaping device 2 for cutting the base of the raised stems, and an auxiliary conveyor for merging the harvested stems. The device 3 is equipped with a rear conveyance device 6 for conveying the combined stem rod to the feed chain 5 of the rear shelling device 4, and the like. The system is configured to automatically and continuously perform operations such as pulling up the stalks as they advance, performing the reaping process, and sequentially handling and shedding the harvested stalks.

To explain the lifting processing device 1, a pair of left and right stem rod locking claws 7b, 8b protruding laterally inward from a pair of left and right cases 7a, 8a are moved upward with their tips facing each other. A pair of left and right stem-rod lifting devices 7, 8 are provided, and the stem-rod locking claws 9b, 10b protruding forward from the cases 9a, 10a are connected to the left and right lifting devices 7, 8.
a pair of left and right first and second stem combing devices 9 for moving upward from near the ground at the front location of 8;
10 are provided. When the first stem combing device 9 performs normal circular mowing work,
In addition, the second pulling device 10 is fixed at the left lateral end position of the left and right pulling devices 7 and 8, where the group of uncut stems will be located adjacent to each other when performing the middle splitting operation. The left and right lifting devices 7 and 8 are configured to be switchable between the right lateral end position and the lateral intermediate position, in which the uncut stem groups are located adjacent to each other only when performing the splitting operation.

The stem rods planted in the field are combed up in advance by left and right first and second combing devices 9 and 10, and then raised to a desired standing posture by left and right lifting devices 7 and 8, In addition, by changing the second combing device 10 to a different position depending on the type of work such as circular cutting work or middle cutting work, it is possible to use the second combing device 10 to cut the grass located at a position corresponding to the front of the machine. A state in which the stems are combed up and then held in that position so that they can be properly transferred to the lifting devices 7 and 8, and a group of stems to be harvested is placed in the uncut stems located on the side of the machine. It is designed to be able to be used in a state where it exerts the effect of separating the entanglement with the group.

Next, a structure for supporting the second stem-and-rod combing device 10 so that it can be moved to different positions will be explained based on FIGS. 2 to 5.

That is, the upper end of the stem-rod combing device 10 is
The horizontal shaft 11 fixed to the upper end of the left and right lifting devices 7 and 8 is connected and supported by a mounting arm 12 which is movable in the axial direction and rotatable around the axis, and the lower end thereof is Divider support rods 1 as combing device support frames provided below the lateral end positions and below the lateral intermediate positions of the left and right lifting devices 7 and 8

Although the embodiment has been described above, the main feature of the present invention is that the replaceable stem-rod combing device is provided at the lower end and at the lateral and lateral center positions of the group of pulling devices. An engaging frame is provided between the supporting frame for attaching the stem rod combing device, which is provided with an abutment surface that prevents movement in the rear direction of the aircraft traveling direction and in the width direction of the aircraft, and the engaging frame is fitted into the engaging frame. The combing device is configured to be able to be selectively supported in two different positions by providing a fixing mechanism configured with a pair of engaged members to be locked.

With the above characteristic structure, the present invention has obtained the following effects. That is, the lower end of the combing device can be supported using the engagement structure in a state where it can be assembled and separated with a simple operation, thereby speeding up and facilitating the replacement work of the combing device. Moreover, the lower end of the combing device is pushed by the stem rod during its operation, and a strong load is applied to the rear, so it is designed to sufficiently support the lower end of the combing device.
While the engagement structure is used to facilitate assembly and separation operations, it is possible to firmly support the assembly without interfering with its operation. As a result, we have achieved a lifting treatment device for a reaping harvester that can be used practically conveniently as a whole.
