Backpack type small berry picking machine

Abstract

A backpack type small berry picking machine comprises a back frame, a miniature gasoline engine, a centrifugal type clutch, a steel wire flexible shaft, a secondary gear drive mechanism, an eccentric vibration mechanism, a housing, a front annular handle, a rear handle, and branch vibrators; the miniature gasoline engine is arranged on the back frame through a vibration isolation rubber pad; an output shaft of the miniature gasoline engine is connected with an input end of the steel wire flexible shaft through the centrifugal type clutch; a square joint of the output end of the steel wire flexible shaft is connected with a square interface of an axle drive bevel pinion of the secondary gear drive mechanism; the eccentric vibration mechanism comprises an upper crank, a lower crank, an eccentric adjustable camshaft, a dual-face guide rail, an upper reciprocating oscillating lever and a lower reciprocating oscillating lever; the branch vibrators are respectively fixed on the front ends of the upper and lower reciprocating oscillating levers; the front portion and rear portion of the housing are respectively provided with a front annular handle and a rear handle; the rear handle is provided with a speed regulator; the speed can be regulated so as to allow the small berry branches to generate different frequency vibrations, and the vibration force can separate the small berries from the branches.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a backpack-type harvesting machine for picking small berries. Background technique [0002] At present, the picking of small berries in China is basically carried out by hand. The maturity period of small berries is short. If manual picking is not timely, the fruit will easily fall off, resulting in waste. Moreover, manual picking requires bending or squatting, which is labor-intensive and expensive. Efficiency is also very low, and the cost of large self-propelled harvesters adopted abroad is high, and they are not suitable for the harvesting operations of small and medium-sized small berry farmers in my country. These factors have seriously restricted the large-scale promotion and planting of small berries in my country. Therefore, the present portable small berry picking machine is an urgently needed product for small and medium-sized small berry planting farmers in my cou...
