A shearing type wolfberry picking machine

Abstract

The invention discloses a shear type wolfberry picking machine, and belongs to the technical field of agricultural machinery. The shear type wolfberry picking machine is composed of a fruit stem cutting unit, a gear transmission unit, an electric control unit and a wolfberry collection unit. A designed divider restrains fruit stems to form a simply supported beam below a branch, and has guiding and clamping functions for enabling wolfberry to enter a cutting area. A divergence structure is designed in the divider, and used for screening green fruits and red fruits. The green fruits are guided out from the side wall of the divider. The red fruits enter the cutting area. Simultaneously, a safe distance between the divider and a blade in the vertical direction is kept, and requirements for the length of the fruit stems of wolfberry are guaranteed. The shear type wolfberry picking machine solves the problems that the wolfberry is difficult to pick, and high in breakage rate, packages of fresh wolfberry are not portable, and labor intensity of picking people is high. The shear type wolfberry picking machine can get rid of topographical limits, adapts to complex operation environment, reduces work strength of labor personnel, and emancipates productive forces. The shear type wolfberry picking machine is simple, portable and small in structure, practical and reliable, and low in cost, improves picking rate and transporting efficiency of the wolfberry, and reduces damage rate of the wolfberry.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a shearing type wolfberry picking machine. Background technique [0002] Lycium barbarum is a berry plant with infinite inflorescences, which has the characteristics of periodic picking. The picking period of wolfberry is from mid-June to mid-October. After maturity, it must be picked within 5 to 7 days. The time span is large and the picking cycle is short. Green fruit and ripe fruit coexist on the same fruit-hanging node, and the growth conditions are complicated. The water content of mature wolfberry is about 80%, and it is easy to be damaged during the picking process. It needs manual selective picking to be completely harvested. The plants are covered with thorns, which are easy to cause hand injury, the picking operation environment is poor, the labor intensity is high, and the manual picking efficiency is low and the cost is high. As the market demand for w...

Problems solved by technology

However, due to the accelerated urbanization process, the number of farmers has dropped sharply. Goji berries are often not harvested in time due to labor shortages, causing serious economic losses.

[0003] In recent years, some goji berry picking machines have been developed in my country, but the picking effect is not very satisfactory. It is easy to cause damage to the goji berry fruit when picking, and the fruit cannot be stored for a long time.

In Chinese patent CN201010272425, the wolfberry picker developed by Cao Youlong and others adopts an eccentric wheel mechanism and uses the vibration principle to pick mature wolfberry, but mechanical vibration can easily cause wrist fatigue and reduce the operator's ability to continue working; the vibration range is wide, and the fruit movement track Harvesting is difficult due to repeated collisions with branches, etc., and the damage is large; in addition, due to the poor consistency of the inertial force from the vibration to the end of the fruit, the fruits at different maturity stages all fall off, making harvesting and sorting difficult

In the Chinese patent CN201010211242, Zhao Weikang et al. developed hob-type goji berries as an optional picking machine, which has a complex structure and cannot be picked for irregularly grown goji berries. Cut off the fruit stalk by the interaction of the hob, otherwise it is easy to cut the fruit, and it also increases the difficulty of the picker's operation
