BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mounts a threshing device on the front part of a traveling machine body, and has a pair of left and right bag support rods for suspending and supporting the upper part of a grain collection bag above the rear part of the traveling machine body. Along with the lower part of the rear part of the traveling machine body, the working posture for projecting rearward from the rear part of the traveling machine body to receive the bottom portion of the grain collection bag, and the storage posture standing upright along the rear wall of the traveling machine body, The present invention relates to a paddy deck structure of a harvester including a paddy deck configured to freely change its posture by vertically swinging around a connection fulcrum with a traveling body.

[0002]

2. Description of the Related Art Conventionally, as a paddy deck structure for a harvester as described above, for example, as disclosed in Japanese Utility Model Laid-Open No. 1-140232, a support suspended from the rear end of a traveling machine body by welding. A paddy deck is pivotally connected to the upper side of the plate so that the paddle can swing up and down, and an operation pedal for lifting the paddy deck by a depressing operation is pivotally connected to the lower side of the support plate, and a paddle is formed by depressing the operation pedal. By swinging the deck up and down, the stagnation of the grains in the grain collection bag that is almost full is resolved, and by lifting the paddy deck by depressing the operation pedal, the bag receiving rod that suspends and supports the grain collection bag. There has been a configuration in which a full grain collection bag can be easily removed from the bag receiving rod by reducing or eliminating the load applied to the bag.

[0003]

However, in the above-mentioned prior art, since the paddy deck and the operation pedal have different structures, and the connection to the support plate is made individually, the paddy deck is It becomes difficult to connect the operation pedal with the operation pedal, and it becomes difficult to assemble the paddy deck and the operation pedal with respect to the support plate on the traveling body side, which causes a troublesome problem.

The object of the present invention is to improve the filling rate of grains in the grain collecting bag and to facilitate the removal of the full grain collecting bag from the bag receiving rod, while also operating the paddy deck. It is an object of the present invention to provide a harvester paddy deck structure that facilitates the engagement with the pedals and the assembly of the paddy deck and the operation pedal with respect to the traveling body.

[0005]

In order to achieve the above object, in the present invention, a threshing device is mounted on the front part of a traveling machine body,
A pair of left and right bag support rods for suspending and supporting the upper part of the grain collection bag are provided above the rear part of the traveling machine body, and below the rear part of the traveling machine body, projecting rearward from the rear part of the traveling machine body It is equipped with a paddy deck configured to be capable of receiving the bottom portion of the collection bag, a storage posture standing upright along the rear wall of the traveling machine body, and a posture that can be freely changed by vertically swinging around a connection fulcrum with the traveling machine body. In the paddy deck structure of the harvester, the paddy deck is provided with an operation pedal for lifting the paddy deck in the acting posture around the connecting fulcrum by depressing the swinging fulcrum provided on the paddy deck.

[0006]

According to the present invention, when the grain collection bag is nearly full, the operation pedal is depressed with a relatively weak force a plurality of times to swing the paddy deck up and down.
The intervals between the grains in the grain collection bag can be reduced,
Thereby, the grain filling rate in the grain collection bag can be improved. Also, when the grain collection bag is full, the tension of the grain collection bag is relaxed by operating the operation pedal with a relatively strong force to maintain the paddy deck in a raised state. It is possible to switch to the state, and it is possible to reduce or eliminate the load applied to the bag receiving rod that suspends and supports the grain collection bag,
This facilitates the operation of closing the fastener provided in the opening of the grain collection bag and the work of removing the grain collection bag from the bag receiving rod. Then, after removing the grain collection bag from the bag receiving rod, the grain collection bag can be easily lowered from the paddy deck by releasing the depression operation of the operation pedal to lower the paddy deck.

Moreover, since the paddy deck is provided with the swinging fulcrum of the operation pedal for lifting the paddy deck, the paddy deck and the operation pedal can be integrally formed. Therefore, the paddy deck and the operation pedal can be combined with each other. It is possible to easily assemble the paddy deck and the operation pedal with respect to the traveling body only by pivotally connecting the paddy deck to the traveling body.

By the way, generally, a harvester has a pair of left and right grain discharge ports, and a switch for switching between a state where grains are discharged from the left grain discharge port and a state where grains are discharged from the right grain discharge port. If the grain collection bag attached to one grain discharge port is full, the lever is provided and the other grain with an empty grain collection bag is operated by operating the switching lever. By discharging the grain from the grain outlet,
Although the grain is prevented from overflowing from the full grain collection bag, if the switching operation of the grain discharge port by the switching lever is delayed, the full grain collection will be recovered. There is a risk that the grains may overflow from the bag. However, in the present invention, even if the switching operation of the grain discharge port by the switching lever is delayed when the grain collection bag is full, it is full by lifting the paddy deck by depressing the operation pedal. Since the grain discharge port on the full side can be blocked by the filled grain and the grain can be discharged from the grain discharge port on the empty side, the overflow of grain from the filled grain collection bag can be prevented. can do.

[0009]

Therefore, according to the present invention, while improving the packing rate of grains in the grain collecting bag and facilitating the removal of the filled grain collecting bag from the bag receiving rod, It has become possible to provide a harvester's paddy deck structure that facilitates the connection between the paddy deck and the operating pedal and the assembling of the paddy deck and the operating pedal with respect to the traveling vehicle body.
