Description

[Detailed description of the invention] The present invention relates to a combine harvester in which a hopper for bagging threshed grain is arranged above the rear of the driver's seat, and a space is provided below the hopper for installation of various control electrical equipment. The purpose is to prevent the aircraft from becoming too large in order to install a storage box for collecting and arranging the equipment, and to ensure sufficient space for workers to inspect internal equipment.

Embodiments of the present invention will be described in detail below with reference to the drawings.

A reaping section 2 for raising and reaping planted stem culms and transporting the reaped stem culms is disposed at the front part of the machine body having a crawler-type traveling device 1, and a driver's seat 3 is provided on the side of this reaping section 2. At the same time, a threshing section 4 is arranged behind the reaping section 2, and a hopper 5 for storing the threshed grain from the threshing section 4 is arranged at the rear upper part of the driver's seat 3, and further below the hopper 5. , bag support rods 6, etc. are arranged, and the paddy bags supported by these rods form an installation space A in which they can expand in response to grain supply, and the system can reap and thresh while traveling in the field. It consists of a combine harvester for carrying grain and bagging the grain.

The reaping section 2 is configured to be freely rotatable up and down around the horizontal horizontal axis P with respect to the machine body, and a sensor S is provided on a divider rod 7 near the ground to swing downward. , is configured to be able to detect the height of the reaping section 2 above the ground based on the amount of rocking of the sensor when the sensor S1 comes into contact with the ground;
Based on this detection result, the cutting height can be controlled by automatically raising and lowering the cutting section 2 using hydraulic pressure so that the height above the ground is as set.

Sensors S2.
S2 is provided so as to be able to freely swing back and forth, and is biased toward the introduction path of the culm to be reaped. It is configured to be able to detect the positional deviation of the aircraft.
Based on this detection result, steering control can be performed to cut off the transmission of driving force to one crawler 1a or 1a, change the direction of movement of the machine, and direct the machine to an appropriate position relative to the stalk culm to be harvested. It is composed of:

The stem culm lifting device 8 of the reaping section 2 is provided with sensors S3, which are spaced apart from each other in the vertical direction, and these sensors S3...
The length of the culm can be detected by contacting the stem with the tip of the culm, and based on this detection result, the reaping stem and culm conveying device 9 is moved to the axis P.
2 to change the delivery position of the harvested stem culm to the threshing feed chain 10, so that the length of the tip fed to the handling chamber of the threshing section 4 is almost constant regardless of changes in the culm length. The structure is such that the processing depth can be controlled so that the depth of handling can be controlled.

A box 11 collects various electrical devices such as relays and fuses for performing the cutting height control, steering control, and handling depth control.
The structure is such that maintenance and inspection can be carried out easily and quickly.

The electrical equipment storage box 11 is installed behind the engine 12 mounted under the driver's seat 3 so as to face the equipment installation space A, and its upper part can be easily removed and operated using butterfly bolts. In addition, the engine 12 is formed so as to be rotatable around the horizontal axis P3 near the lower end, and the engine 12 can be inspected in the rotated state.

The lid 13 of the box 11 is designed to be removable by swinging or attaching/detaching toward the installation space A, so that the installation space A can be easily used as a work space for maintenance and inspection of internal equipment. It is composed of:

In summary, the present invention provides the combine harvester described at the beginning, in which an electrical equipment storage box is provided at the bottom of the seat or at the rear of the bottom, and the box 11 is provided with a lid that opens the box 11 toward the equipment installation space. It is characterized by

In other words, the electrical equipment storage box installed at the bottom or rear of the seat faces the bagging space at the bottom of the rear of the seat, making it more compact without requiring major design changes to install the box. Moreover, since the box lid can be opened toward the bagging space, the bagging space can be used as a work space for inspecting the equipment inside the box, and the parts can be placed on the bagging machine stand. It has now become possible to perform inspections and other tasks easily without contaminating parts.
