Harvesting Structure of Root Vegetable Harvester

The present invention mainly relates to a harvester configured to extract root vegetables such as carrots, radishes, etc. to carry out leaf cutting.

(Conventional technology)

As the root vegetable harvester, a harvesting conveying device which is fitted with root vegetable leaf parts such as carrots and radishes planted in a field, is pulled upward and leaned upward from the rear of the machine body to one side of the machine body. A leaf cutting device for cutting the root vegetable foliage from the harvesting conveying device, a recovery section for recovering the root vegetable harvest from the leaf cutting device, and discharging the cutting foliage from the leaf cutting device outside the machine body. Root vegetable harvesters with a foliage transport device are proposed.

The root vegetable harvester, for example, install a transport mechanism for aligning the position of the root vegetable toward the leaf cutter device, and the root vegetable rises as it is conveyed to the rear, the root vegetable tofu eventually Can be configured to be in a contact conveyance state in contact with the roller.

However, when a spring structure for pressing the left and right rollers together to hold the foliage is used, the rolls or chain links supporting them are spaced apart in the rotational motion plane direction of the chain, and adjacent to each other in the transport direction in the rotational motion portion of the front sprocket. A large space | interval arises between rollers which become, and the closed end by which a foliage part is fitted in the clearance gap arises.

An object of the present invention is to provide a conveying device that can be conveyed favorably the foliage of the root vegetable.

(Means to solve the task)

In order to achieve the above object, the leaf part of the root vegetable of the present invention is sandwiched (葉 部) by pulling the root vegetable up in the ground while pulling upwards, the rear end of which is driven by being placed in an inclined state with a high back side. A conveying device for conveying the root vegetables conveyed from the pulling unit to the rear, comprising a part of the endless rotating belt conveying mechanism, and a conveying mechanism for position alignment disposed below these; At that time, the leaf portion of the root vegetable is guided to the positional conveying mechanism, the upper portion of the leaf portion adopts the harvesting structure of the root vegetable harvester, which is transported by the endless pivot belt conveying mechanism, the endless pivot belt The endless rotating bell so that a vertical distance between the conveying mechanism and the positioning alignment conveying mechanism becomes wider toward the lower side in the conveying direction The conveying mechanism and the positional conveying mechanism are arranged relatively, and the root vegetables are allowed to move from the endless pivot belt conveying mechanism to the positional conveying mechanism by the predetermined downward movement force applied to the conveying root vegetable. The endless rotation belt conveyance mechanism is set by the endless rotation belt conveyance mechanism, and the force which clamps a leaf part is wound, and the said position alignment conveyance mechanism is rolled over the front and rear wheel bodies, and this pressurization state is applied to this endless rotation stage. The relative positioning of the left and right endless rotating belts is determined so that the root vegetable lobe is positioned between the rollers of the left and right position alignment transport mechanisms, and the position of the endless rotating belts is determined. The axis of rotational movement of the roller is set so that the shank-dong of the root vegetable leaf held by the alignment conveying mechanism is allowed. .

And in the area | region where the endless rotating belt of the said positioning alignment conveyance mechanism is wound by the said front body, the guide means which prevents a root vegetable leaf part from entering into the clearance gap between adjacent rollers is provided. Since the leaf part is prevented from being inserted between the rollers adjacent to each other in the conveying direction by the guide means, the root vegetable head is not in contact with the roller, so that the root vegetable can be delivered with the positioning mechanism without closing the root vegetable. The contact conveyance state where the head is in contact with the roller is surely realized.

Therefore, according to the present invention, the root vegetable harvester capable of mechanizing a series of processes of pulling the root vegetables out of the ground and transporting them immediately to the post-treatment such as a cutter device, stably maintains the roots guided by the post-treatment. Positioning conveyance mechanisms for aligning with position can be provided in a surely functioning state.
