Variable-cutter-gap two-degree-of-freedom hydraulically-driven sugarcane cutting device

Abstract

The invention discloses a variable-cutter-gap two-degree-of-freedom hydraulically-driven sugarcane cutting device. The sugarcane cutting device comprises feeding rollers, two groups of disc cutters, two groups of outer sleeves, two parallel fixing plates, a cutter mounting shaft and adjusting mechanisms. A cutter rotating shaft is mounted on each disc cutter, one end of each cutter rotating shaft is fixed to the corresponding disc cutter, and the other end of each cutter rotating shaft penetrates into a corresponding outer sleeve to be connected with a disc cutter motor. The cutter mounting shaft is parallel to the feeding rollers, and the adjusting mechanisms are used for adjusting a horizontal distance between the two disc cutters. The horizontal distance between the two disc cutters is changed through the adjusting mechanisms, and each adjusting mechanism comprises a screw motor, a moving block and a screw; a five-link mechanism is arranged at each of two ends of the cutter mounting shaft to play a role in lifting or descending of the disc cutters on the cutter mounting shaft. Compared with the prior art, the sugarcane cutting device have advantages of simple structure, cutting stability of the disc cutters, quickness and convenience in cutting and wide applicability.

Description

technical field [0001] The invention relates to a cutting device, in particular to a two-degree-of-freedom hydraulically driven sugarcane cutting device with variable cutter head clearance, belonging to the technical field of agricultural machinery. Background technique [0002] As a large and heavy agricultural machinery, the sugarcane harvester can effectively improve the harvesting efficiency of sugarcane and greatly reduce the labor intensity of farmers. However, most of our country is a hilly landform, especially in the south as a sugarcane planting area, it is difficult to directly use large sugarcane harvesters. Instead, when working, the cutting device is lifted to adapt to the uneven hilly terrain. Since the cutter for cutting sugarcane is installed on the sugarcane cutting device, it is necessary to accurately lift the sugarcane cutting device to a suitable position while ensuring the stability of the cutter, so as to ensure the quality of the sugarcane root cutti...

AI Technical Summary

Problems solved by technology

The two sets of double-helix cutters designed by it are driven by the gear box to cut sugarcane. Although this cutting device can cut quickly, the two sets of double-helix cutters are fixed installation structures and cannot be used for different planting rows. Adjusting the spacing of the cutter head with the sugarcane at the same distance has poor applicability; at the same time, it cannot lift the cutter according to the terrain of different heights, which not only easily damages the cutter, but also reduces the cutting efficiency of the sugarcane device
