Energy-saving high-efficiency tapioca root harvester

Abstract

The invention discloses an energy-saving high-efficiency tapioca root harvester comprising a lifting traction subassembly, a pull rod, a frame and perching knife subassemblies, wherein the lifting traction subassembly is articulated on a vehicle body, the pull rod is fixed on the vehicle body, the lifting traction subassembly is articulated with a hanging hole seat at the front end of the frame, and the pull rod is articulated with a connecting long plate of the frame. The energy-saving high-efficiency tapioca root harvester is characterized in that each perching knife subassembly comprises asupporting post, a shovel holder, wing shovel fixing plates, a wing shovel and a shovel point; the upper end of the supporting post is fixed at the bottom of a main beam of the frame, the lower end ofthe supporting post is provided with the shovel holder, the front end of the shovel holder is provided with the shovel point, both sides of the shovel holder are provided with the sloping wing shovelfixing plates, and the wing shovel is connected with the wing shovel fixing plates in a removable mode. The three perching knife subassemblies are not arrayed side by side but in a staggered mode, each wing shovel only harvests a half ridge of tapioca roots, and therefore, the perching knife subassemblies greatly reduce the operation resistance. The energy-saving high-efficiency tapioca root harvester has low energy consumption and high production efficiency and can regulate the burying angle and the burying depth of the perching knife subassemblies by the telescopic pull rod and a connectingrod.

Description

technical field [0001] The invention relates to an agricultural machine for harvesting underground root crops, in particular to an energy-saving and high-efficiency cassava root harvester. Background technique [0002] The cassava harvested product is mainly underground tubers. Cassava roots are harvested in a large amount. At present, most areas in my country basically rely on manual operations, using hand or simple potato pulling tools and digging with a hoe. Each person only harvests about 0.4 mu per day. As a result, cassava root harvesting has become the most labor-intensive and labor-intensive operation in the current cassava production process, and the productivity of manual work is low, and the operating cost is high. Crunchy, resulting in large damage to the root tubers, especially for more viscous soils, it will cause greater root tuber loss and damage. [0003] In addition, in a small number of areas in my country, after cutting off the stems manually, animal po...

AI Technical Summary

Problems solved by technology

However, because the left and right blades of the V-shaped blade each harvest a ridge of tubers, the length of the left and right blades is large, resulting in heavy load and low strength of the machine tool, resulting in high operating costs, low productivity, and poor reliability of the machine tool.

At present, the machine is still in the process of testing and improving, and there is no major progress.
