An example of the integrally rotating combine harvester shown in Figs. 1 and 2 is shown below. In the integrally rotating combine harvester, the reaping conveyance section and the threshing device are moved up and down as one, so the distance between the two devices is does not change, and the dustproof cover 2 can be fixed to both devices.

On the other hand, in the case of the reaping rotary type combine harvester shown in Fig. 4, the threshing device is fixed to the shear sea, so only the reaping and conveying device rotates, and the distance between the two is small when moving up and down. It changes.

For this purpose, the dustproof cover shown in Figure 3 pivots at the rear end,
The front end is configured to be slidable.

Explaining the work process of a combine harvester.

The plant base is divided to the left and right by a weed dividing board 1, and a pulling device 2 is guided for each row. While the grain culm is pulled up by the lifting device 12, the stalk part is cut by the cutting blade device 19, and then transported to the lower part of the vertical conveying device 24 by the grain stalk conveying device. After being transferred from the stock transfer device to the vertical transfer device 24, the stock portion is rapidly lifted and transferred to the feed chain 5. After the tip of the grain is pulled up by the raising device 12, the tip is conveyed to the handling chamber entrance 22 of the handling barrel 16 of the threshing device by the tip conveying device.

The position of the tip of the tip is detected as shown in FIG. 4 while the tip is placed on the iron plate at the entrance of the handling chamber entrance 22, and the tip is moved to the vertical conveyance device 24 so that the tip of the tip is in the optimum position for the handling teeth 13 of the handling barrel 16. It is automatically controlled. Conventionally, this handling depth sensor and sensor box have been fixedly installed on the front plate of the threshing device, etc. above the handling room entrance 22.

8 is a cooler type traveling device, 7 and 7' are grain receiving devices, and 20 is a grain frying conveyor.

In contrast, in the present invention, the pulling device 12, the cutting blade 1
9. A dustproof plate 2 is provided on the top of a reaping conveyance device consisting of a stock conveyance device, a vertical conveyance device 24, an upper conveyance device, etc., and a handling depth sensor 10 and a sensor box 11 are installed vertically from the dustproof plate 2. It is.

In the case of FIGS. 1 and 2, the combine harvester is an integrally rotating type, so the dust cover 2 is attached to the lifting device 12.
It may be fixed between the upper horizontal plate 9 and the front end of the handling barrel cover 6 of the threshing device.

However, since the dust-proof cover 2 is often opened to prevent blockage or adjustment of the reaping and conveying device, the hinge 23
It is pivotally supported on the handling trunk cover 6 at the handle 15, and is also provided with a handle 15 for lifting.

By providing this dustproof cover 2, it is possible to reduce dust on the operator sitting on the seat 4 with the control column 3 in front.

The present invention has a straight or curved groove 2a in the left and right direction as shown in Figs. It is said that

As shown in FIG. 4, the sliding body 18 is placed on the bottom surface of the dustproof cover 2, and the adjustment handle 14, which is a part of the sliding body 18, is screwed into the screw hole of the sliding body 18, and the dustproof cover is held between the two. It is fixed.

With this configuration, without opening the dustproof plate 2,
While the dustproof plate 2 is closed and prevents dust from blowing out, the position of the sensor box 11 can be adjusted by operating the adjustment handle 14.

A hanging rod 17 is fixed to the sliding body 18, and a sensor box 11 is fixed to the hanging rod 17.
Handling depth sensor 10H in sensor box 11,
10L is pivotally connected. These form a handling depth sensor device.

By moving the handling depth sensor device fixed and slidably supported in the groove of the dustproof cover 2 in this way with respect to the handling cylinder entrance,
It is possible to adjust where on the handling barrel the tip of the grain culm is positioned.

As shown in FIG. 4, the adjustment handle 14 can be loosened and moved from side to side, and the adjustment handle can be tightened at the moved position.

Further, as in the embodiment shown in FIG. 2, if the groove 2a is bent greatly and positioned close to the seat, the handling depth sensor device can be moved to the position of the adjustment handle 14' and stored. be.

In the case of the embodiment shown in FIG. 3, it is a reaping rotation type combine harvester, and only the reaping and conveying device is rotated by the hydraulic cylinder 20, so the distance between the horizontal plate 9 of the hoisting device 12 and the handling trunk cover 6 is changes, so the rear end of the dustproof cover 2 is pivoted with a hinge 23,
A rotating roller 21 is installed at the front end to improve sliding.
is provided.

In other respects, it is equivalent to an integrally rotating combine harvester. As the reaping conveyance device rotates, the distance between the handling depth sensor device and the grain culm changes.
It is okay because there is no such large rotation during reaping.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, by providing a wide dustproof plate 2 that can be opened and closed, it prevents rainwater from falling on the sensor box 11 during reaping work in the rain, and also prevents dust generated from the reaping transport section from falling on the operator. The dustproof plate can be used to protect the handling depth sensor and the sensor box from rainwater and obstacles, and when the dustproof plate 2 is opened, it will protect the conveying section and the sensor. This means that maintenance, inspection, repair, cleaning, etc. can be easily performed.

Second, since the sensor box 11 is installed below with a space between it and the bottom surface of the dustproof plate 2, the dustproof plate 2 and the sensor box 11 can be installed at their respective suitable heights, and the dustproof Plate 2 has good dustproof properties, and also has a handling depth sensor 1.
0 means that it can be installed and configured well so that it can accurately contact the tip of the grain culm to be transported.

Thirdly, the present invention has a simple structure in which the supporting member of the sensor box is fixed to the sliding body that slides in the guide groove on the dustproof plate, and the dustproof plate 2 can be kept closed. The position of the sensor box 11 can be adjusted according to the culm length, and dust can be prevented from being blown out each time the adjustment is made. Therefore, the working environment can be significantly improved without increasing costs.

Fourth, since the sliding body is provided so as to protrude above the dustproof plate, the sensor position can be confirmed even when the dustproof plate is closed, allowing the operator to find the appropriate position without covering himself with dust or dirt. The sensor can be adjusted to Furthermore, even if the dustproof plate is made transparent, dirt and dust may adhere to it, reducing its transparency and making it impossible to see inside the dustproof plate from the driver's seat. You can check this and make appropriate sensor position adjustments.
