Abstract

The invention discloses a vibration digging and pulling type cassava harvester which comprises a rack, a hanging frame, a tuberous root pulling device, a digging shovel and an electro-hydraulic control device. The rack is composed of a beam frame and a rear supporting wheel. The rack is hinged to the hanging frame, and longitudinal displacement, relative to the hanging frame, of the rack is limited through a steel chain. The tuberous root pulling device is composed of a pulling mechanism, a vibration mechanism and a clamping mechanism. The tuberous root pulling device is installed on the rack. The digging shovel is composed of a subsoiler and a subsoiler pillar and fixed below a cross rod of the hanging frame through a U type bolt. The electro-hydraulic control device is composed of a sensor, a single-chip microcomputer, an A/D, an electro-hydraulic servo valve and a D/A. The electro-hydraulic control device controls a hydraulic motor and an oil cylinder to work. The vibration digging and pulling type cassava harvester is connected with a tractor hanging device through the hanging frame in a three-point mode. The vibration digging and pulling type cassava harvester is simple in structure, high in flexibility of the pulling mechanism, easy to control and capable of achieving fast and continuous pulling and is little in loss, clean in soil and cassava separation and low in power consumption when cassava tuberous roots are harvested.

Description

technical field [0001] The invention relates to a harvesting machine in the field of agricultural machinery, in particular to a vibrating digging and pulling type cassava harvester. Background technique [0002] Cassava is widely planted in the tropics and subtropics. It is a root crop and is known as the "king of starch". Its output ranks sixth among food crops. It is the food that 600 million people in the world depend on for survival and is an important bioenergy crop. At present, domestic cassava root harvesting is basically done manually, with heavy workload, low efficiency and high harvesting cost. During the harvest season, due to low harvesting efficiency and long harvesting time, many cassavas germinate and rot in the ground, resulting in a reduction in cassava production, which seriously hinders the development of cassava planting and becomes a "bottleneck" for the development of cassava planting. Therefore, to carry out research on cassava harvesting machinery an...
