Reciprocating double-movable-knife bush harvester

Abstract

The invention relates to a reciprocating double-movable-knife bush harvester. The harvester mainly consists of an outer slide palm component, a knife beam, an upper movable knife, a lower movable knife, a blade pressing (supporting) component, a floating branch-collecting mechanism, an eccentric shaft type double-crank linkage mechanism, flywheels, a frame, an inner slide palm component, a transmission mechanism, transmission belt wheels, a transmission belt, a suspension frame and the like; the eccentric shaft type double-crank connecting rod mechanism is mainly composed of an upper knife holder, rocker knife-holder connecting plates, rockers, a base, eccentric shafts, connecting rods, a lower knife holder and other components; the upper and lower movable knives are driven by two eccentric shafts and make constant-speed relative movement during work; the transmission belt wheels, the flywheels and the two eccentric shafts are located separately at both ends of a mandrel passing through the base; the frame is connected with a small four-wheel tractor in a rear suspension way; and the eccentric shaft type double-crank linkage mechanism converts rotary motion during transmission intoreciprocating linear motion of the knives. The harvester of the invention has the advantages of simple structure, stable performance, smooth operation, high harvesting efficiency and good stubble quality, and can satisfy high-speed harvesting requirements of small-sized bushes.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a reciprocating double-knife shrub harvester. Background technique [0002] Shrubs not only have the characteristics of windbreak, sand fixation and water and soil conservation, but also a good forage plant. Caragana shrubs for feeding should take 2 years as a harvest cycle, and the harvest is best during the flowering period. At present, domestic and foreign shrubs are mainly harvested by rotary cutters. However, there are problems such as poor cutting quality, high missed cut rate, and entanglement when rotary cutters harvest young and small-diameter Caragana shrubs in the growing season. For this reason, combined with the characteristics of the current forage caragana shrub harvesting, and referring to the double-moving knife lawn mowers that harvest high-yield artificially planted forage grass in European and American countries, a reciprocating double-moving k...
