構造に関する。[Detailed description of the invention] [Industrial field of application] The present invention is designed so that the rear end of the frame of the reaping section is vertically swiveled to the upper free end side of an arm that is connected to the front part of the machine so as to be swingable back and forth. The arm is movably connected and can be switched between a state in which the arm is fixed to the machine body side and a state in which it can freely swing back and forth, and a handling depth adjustment lever is attached to the fixed part of the reaping part so that it can be freely swung back and forth and the arm can be moved back and forth. The present invention relates to a handling depth adjustment structure for a combine harvester, in which a rear conveyance device for adjusting the handling depth is mounted in a state in which it is moved upward by swinging.

In such a combine harvester adjustment structure, the rear conveyance device for adjusting the handling depth can be vertically swung around the rear fulcrum, and the rear conveyance device can be supported by the handling depth adjustment lever to set the desired inclination angle. Because of this configuration, when the lever is swung backward to move the rear conveyance device upward, the load of the rear conveyance device is directly applied to the lever. Therefore, the U.S. government opened in 1978.
As disclosed in Japanese Patent No. 18434, a spring for balance adjustment is installed between the handling depth adjustment lever and the auxiliary frame of the reaping section, and the lever is oscillated rearward. There is a known device that cancels out the forward swinging force of the lever caused by the load of the conveying device, thereby making it possible to swing the lever easily.
上述したように、バランス調節用のバネを装着

けに多大な労力を要していた。
As mentioned above, the handling depth adjustment lever can be operated easily by installing a balance adjustment spring, but the spring does not have sufficient elasticity to support the load of the rear transport device. Therefore, when the spring is attached, a large force is required to elastically deform it to the desired length, and a great deal of effort is required to assemble the spring.
本考案は、上記実情に鑑みてなされたものであ
つて、扱深さ調節レバーを後方に揺動付勢するた
めのバネ付勢機構の脱着を容易に行えるコンバイ
ンの扱深さ調節構造の提供を目的とする。 The present invention has been made in view of the above circumstances, and provides a handling depth adjustment structure for a combine harvester in which a spring biasing mechanism for swinging and urging the handling depth adjustment lever rearward can be easily attached and detached. With the goal.

In other words, when the arm that supports the reaping section is switched to a state where it can freely swing back and forth and is further swung forward, the reaping section will shift forward and the gap between the machine body and the reaping section will open, allowing maintenance in this area to be performed. It becomes easy to do. At this time, the portion of the arm above the reaping section frame connection point leans forward and approaches the handling depth adjustment lever. Therefore, when the reaping section is shifted forward in this way, the handling depth adjustment lever If a spring biasing mechanism with a natural length or a length close to this is installed between the lever and the upper part of the arm, when the reaping part is returned to its normal position, the lever and the upper part of the arm will The gap widens, and at the same time the spring biasing mechanism is stretched to the desired length, thus inevitably accumulating elastic energy.
