Description

Detailed Description of the Invention A. Object of the Invention [Field of Industrial Application] The present invention relates to a pulse harvester. In more detail, the work can be switched freely between spreading the harvested beanpoles on the reaping field and drying them on the ground, and picking up the harvested beanpoles or dried beanpoles and storing them in storage containers such as baskets and net bags. The present invention relates to a bean rod conveying device in the constructed bean harvesting machine.

[Prior Art] Generally, a bean harvester conveys the bean rods sent from a reaping device or a pick-up device at the front of the machine frame to the rear of the machine frame via a conveyor that slopes upward. When storing beans in a storage container as disclosed in No. 55-9473 and Japanese Patent Application Laid-open No. 56-75017, even if the beans are dropped from the upper end of the conveyor into the storage container, the beans that come out from the burst pods will not be stored in the storage container. There is no problem since I will enter.

However, when dropping the beans from the upper end of the conveyor onto the harvested field for drying, the pods burst and the beans are scattered on the field. The device becomes complicated because it is necessary to drop the bean rods in two stages via a guide receiver provided between the top end of the conveyor and the field to alleviate the impact on the bean rods and prevent them from popping.

[Problem that the invention seeks to solve]

The present invention improves the above-mentioned conventional example during the drying operation by configuring one bean rod conveyor to be used selectively for storing the bean rods in a storage container and for drying the beans on the ground. The purpose is to improve problems.

B. Structure of the Invention [Means for Solving Problems] The present invention provides a drive pulley 14 on a drive shaft 15 which is horizontally mounted above a substantially central portion of a machine frame 1 of a traveling vehicle and is driven by a hydraulic motor M1; A bevel locking protrusion 1 is provided between the upper and lower turning drums 13, 13, which are arranged at approximately the same distance from the drive shaft 15 at the lower front and upper rear of the traveling vehicle.

This is a bean rod conveying device in a bean harvester that is bent so that its tip is at a height close to the field.

[Effect]

With the above configuration, when storing harvested bean sticks or picked up bean sticks in the storage container 5 on the trailer 17, the upper conveyor 2H is pushed up by the hydraulic cylinder 19 and stretched out on the approximate extension line of the lower conveyor 2L. Place the tip of the upper conveyor 2H into the storage container 5.
position directly above the upper opening of the

Then, the conveyor 2 is driven by the hydraulic motor M1, and the bean rods transferred from the reaping device 3 or the picking device 4 and transferred onto the conveyor 2 are transferred to the conveyor belt 2.

C. Effects of the Invention The present invention provides a bean rod conveying device for a bean harvester, in which when the upper conveyor of the conveyor is extended on the extension line of the lower conveyor, the tip of the upper conveyor is
It is located at a height directly above the upper opening of the storage container on the trailer, and can be harvested by cutting or picking up. By bending the upper conveyor in a substantially inverted shape with respect to the lower conveyor, and placing the tip of the upper conveyor at a height close to the cutting ground,
By gently dropping the bean pods onto the field, you can dry them directly on the ground by preventing the bean pods from bursting due to impact.

The upper and lower conveyors are made up of several threads of a single rubber belt, which bends and stretches along the drive pulley at the center of the belt in the direction of conveyance, so there is no shifting of the bean rods when extending or bending. Therefore, continuous conveyance is performed smoothly. Since the bending/extension is performed by a hydraulic cylinder supporting the upper conveyor, it can be easily switched.

Furthermore, since the parallel rubber belts, the outermost receiving plate, and the vertical side plate at the outer edge of the outer receiving plate are provided, the bean rods will not fall off the conveyor. Since the receiving plate and the side plate are divided into upper and lower parts at the drive shaft position in the center, the bending and stretching of the conveyor can be carried out easily.
