Improved rotary disk type potato harvester

Abstract

The invention relates to agricultural machinery, in particular to a harvester of potatoes, sweet potatoes and the like of rhizomes of crops, more particularly to an improved rotary disk type potato harvester which mainly comprises a main body consisting of a disk type stand body, a rotary disk separating mechanism, a transmission mechanism and an incline adjusting mechanism. The improved rotary disk type potato harvester is characterized in that an input hole and a digger blade are arranged at the lower end in the front of the disk type stand body, the upper end in the front of the disk type stand body is connected with a traction bracket, the incline adjusting mechanism is connected in the rear of the disk type stand, the transmission structure is arranged on the upper end of the disk type stand body, one side surface of the disk type stand body is provided with a discharging hole or connected with a recovering structure, and the rotary disk separating mechanism is arranged in the disk type stand body. The improved rotary disk type potato harvester has the advantages of more rapidly and completely separating soil and screening potatoes without easily damaging the machinery, prolonging the mechanical service life, being not easy to cause soil adhering, reducing the abrasion to the potato and being safe in use.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a machine for harvesting potatoes, sweet potatoes, and other crops, in particular to an improved rotary-disc potato harvester. Background technique [0002] Existing potato harvesting machines are used in some farms and concentrated potato production areas. Although potato harvesting machines can achieve mechanized harvesting, they are bulky, heavy, and costly to use. In particular, some harvesting machines use metal curtains Conveyor belts or metal rods are easy to cause a large amount of clay, and easy to cause mechanical damage, resulting in low use efficiency and difficult promotion. For example, the patent document I submitted for application and publication is: Rotary Disc Potato Harvester, application number: 201010158216.2 claims and technical solutions, although this patent has the ability to quickly and fully separate soil and screen potatoes in practical applications, and doe...

[0002] Existing potato harvesting machines are used in some farms and concentrated potato production areas. Although potato harvesting machines can achieve mechanized harvesting, they are bulky, heavy, and costly to use. In particular, some harvesting machines use metal curtains Shaped conveyor belt or metal rod conveying, it is easy to cause a large amount of clay, and it is easy to cause mechanical damage, resulting in low use efficiency and difficult to promote, etc.

For example, the patent document I submitted for application and publication is: Rotary Disc Potato Harvester, application number: 201010158216.2 claims and technical solutions, although this patent has the ability to quickly and fully separate soil and screen potatoes in practical applications, and does not It is easy to cause mechanical damage, prolong the service life of the machine, is not easy to cause clay, reduces wear and tear on potatoes, and is safe to use. However, in the traction structure described in this plan, the rear end of the digging shovel is connected to the keel frame, and the gear box is placed in the keel frame , the keel frame is placed at the lower end of the turntable separation mechanism, which causes a part of the soil to be affected by the keel frame and cannot be separated quickly in time, resulting in a slower separation speed. At the same time, there are many structures including the traction structure, resulting in higher manufacturing costs , still needs further improvement
