Root-tuber crop harvester

Abstract

The invention provides a root-tuber crop harvester which comprises a rack and a digging shovel and further comprises a vibrating screen, a vibrating mechanism and a conveying mechanism. The front end of the digging shovel is a cutting blade portion, the cutting blade portion consists of at least two parallelly arranged and adjacent rectangular blades, the front ends of the rectangular blades are circular-arc-shaped. The vibrating screen comprises a top screen net and a screening assembly, wherein the screening assembly comprises at least two parallelly arranged toothed plates and at least two parallelly arranged guide pipes, at least two triangular teeth are arranged at the upper portion of each toothed plate, and the screening assembly is located on the upper surface of the top screen net. The digging shovel is fixed to the front end of the bottom of the rack, the vibrating screen is located at the rear end of the bottom of the rack and is connected with the rack through the vibrating mechanism, and the conveying mechanism is located between the digging shovel and the vibrating screen. The root-tuber crop harvester saves effort in soil piercing and facilitates separation of plants and fruits of crops.

Description

technical field [0001] The invention relates to the technical field of rhizome crop harvesting machinery, in particular to a rhizome crop harvester. Background technique [0002] Rhizome crops include peanuts, potatoes, sweet potatoes, and heterophylla, etc., whose fruits are in the soil and connected to the roots of the plants. Traditional root crops are mainly harvested by manual digging, which is labor-intensive for farmers and low in harvesting efficiency. [0003] The Chinese invention patent with publication number CN105027800A discloses a rhizome crop harvester, which includes a frame, a blade positioned at the front end of the frame, and a vibrating screen positioned at the middle and rear of the frame. The shape of the blade is trapezoidal, and the blade and The back of the knife is the two bottoms of the trapezoid, and the back of the knife is longer than the edge of the knife; the transmission mechanism of the vibrating screen is set as follows: the output shaft o...
