Problems solved by technology

[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. The efficiency is also very low, and the large-scale self-propelled harvesters used abroad are expensive and 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

Embodiment 1

[0019] Backpack small berry picking machine, its main components include back frame 1, small gasoline engine 2, centrifugal clutch 3, wire flexible shaft 4, secondary gear transmission mechanism, eccentric vibration mechanism, eccentric adjustable camshaft 10, branch vibrator 25 , casing 6, front ring handle 11, rear handle 5 and speed regulating device 13, described knapsack type small berry picking machine is characterized in that small gasoline engine 2 is installed on the back frame 1 by vibration-isolation rubber pad, and the small gasoline engine 2 The output shaft is connected to the input end of the flexible steel shaft 4 through the centrifugal clutch 3, the square joint at the output end of the flexible steel shaft 4 is connected to the square interface of the active bevel gear shaft 14 of the secondary gear transmission mechanism, and the eccentricity of the output end of the secondary gear transmission mechanism The adjustable camshaft 10 is assembled with the large...

Embodiment 2

[0023] The eccentric adjustable camshaft 10 is assembled from a stepped shaft 17, an eccentric wheel set, a key, a bushing and a shaft end stop ring. The eccentric wheel set includes two upper and lower eccentric wheels 21 with the same shape and size. Described eccentric wheel 21 is to process an eccentric shaft hole on the circular pie-shaped steel plate, and open a keyway on the eccentric shaft hole, and its keyway is positioned at the radial line of the eccentric shaft hole perpendicular to the eccentric wheel 21 symmetrical center line, The upper and lower eccentric wheels 21 are symmetrically fitted on the stepped shaft 17 according to the forward and reverse directions, and are fixed with keys, bushings and shaft end retaining rings. Since the upper and lower eccentric wheels 21 are reversely symmetrically arranged, the The centrifugal forces of the two eccentric wheels cancel each other out, thereby effectively reducing the vibration of the handle caused by the centrifu...

Embodiment 3

[0025] The eccentric vibration mechanism includes an upper crank 22, a lower crank 23, an eccentrically adjustable camshaft 10, a double-sided guide rail 8, an upper reciprocating vibration rod 12 and a lower reciprocating vibration rod 20, and the upper crank 22 and the lower crank 23 have a large shaft The holes are respectively assembled with the upper and lower two eccentric wheels 21 of the eccentrically adjustable camshaft 10 through bearings, and the small shaft holes are respectively fitted with the shaft holes at the rear ends of the upper reciprocating vibrating rod 12 and the lower reciprocating vibrating rod 20 through pin shafts. And symmetrically arranged on the upper and lower sides of the double-sided guide rail 8, when working, the acceleration directions of the upper and lower reciprocating vibrating rods at any time are always opposite, and the generated reciprocating vibration inertial forces cancel each other out, thereby effectively reducing vibration. The...

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...
