Rotary disc type tubers harvester

Abstract

The invention relates to the agricultural machinery and in particular relates to a further improved multipurpose harvesting machine for tubers of crop rootstalks including potatoes, yams and the like, specifically to a rotary disc type tubers harvester. The harvester provided by the invention takes a rotary disc separating device as a body and is characterized by that: the rotary disc separating device is installed between an upper circular bracket and a lower circular bracket, an input opening and a digger shovel are distributed in front of the rotary disc separating device, the upper end ofthe input opening is connected with a suspension bracket and a dragging bracket, and the rotary disc separating device is equipped with a convex cone-shaped rotary disc mechanism or a concave cone-shaped rotary disc mechanism. The harvester provided by the invention can rapidly and completely separate soil and sieve tubers and is not easy to cause mechanical damages, prolongs the service life of the machine, is not easy to cause clay, reduces abrasion on the tubers, and has a safe use; meanwhile, the harvester has a flexible movement, can be suitable for the work of different soils, reduces construction cost, and has a light weight and the like.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a multi-purpose harvesting machine further improved for crop roots such as potatoes and sweet potatoes, in particular to a rotary table potato harvester. Background technique [0002] Existing potato harvesting machines are used in some farms and concentrated potato production areas. In particular, although existing potato harvesting machines can achieve mechanized harvesting, they are bulky, heavy, and costly to use, especially for some commonly used harvesting machines. Using metal curtain conveyor belt or metal rod conveying, it is easy to cause a large amount of clay, especially when encountering stones, it is easy to cause mechanical damage, because the metal rod is very easy to enter the soil when using metal curtain conveyor belt or metal rod conveying in front Wear and tear, the service life is very short, because the conveying method is adopted, it must form an up and down cycl...

Problems solved by technology

[0002] Existing potato harvesting machines are used in some farms and concentrated potato production areas. In particular, although existing potato harvesting machines can achieve mechanized harvesting, they are bulky, heavy, and costly to use, especially for some commonly used harvesting machines. Using metal curtain conveyor belt or metal rod conveying, it is easy to cause a large amount of clay, especially when encountering stones, it is easy to cause mechanical damage, because the metal rod is very easy to enter the soil when using metal curtain conveyor belt or metal rod conveying in front Wear and tear, the service life is very short, because they all adopt the conveying method, they must form an up and down cycle rotation, so two upper and lower conveyor belts are formed to filter and separate the soil, resulting in slow speed, low benefit, and difficult to promote, etc.
