Self-adaptive oil palm fruit picking cutter and picking execution device thereof

Abstract

The invention discloses a self-adaptive oil palm fruit picking cutter and a picking execution device thereof. The cutter comprises a shearing assembly and a self-adaptive clamping assembly. The shearing assembly comprises two blades with cutting edges arranged in a staggered manner, a connecting rod mechanism and a shearing oil cylinder. The self-adaptive clamping assembly comprises oppositely-opened special-shaped claws. The picking execution device comprises a cutter, a first axial rotation mechanism, a longitudinal rotation mechanism and a second axial rotation mechanism, the first axial rotation mechanism, the longitudinal rotation mechanism and the second axial rotation mechanism drive the picking cutter to achieve up-down, left-right multi-angle movement, and therefore fruits at different positions can be accurately positioned, and the optimal shearing angle is achieved. According to the picking tool and the picking execution device, fruits can be accurately and effectively positioned through a tool bit adjusting device, the picking tool and the picking execution device are suitable for oil palm fruits of different sizes, hooking and fruit falling caused when leaves are sheared are avoided, the picking procedure is simplified, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural product harvesting, in particular to an adaptive oil palm fruit picking cutter and a picking executive device. Background technique [0002] At present, the degree of mechanization of the oil palm planting industry is quite low. Oil palms are mainly produced in Southeast Asian countries, Africa, and South America. The real-time height of oil palm trees is more than 3 meters. Manual picking. When picking, it is necessary to cut the leaves under the fruit first, and then cut the oil palm fruit, and not damage other leaves and immature fruits. The labor intensity and difficulty are relatively high, and the fruit of the tree falls to the ground when picking , will cause a certain degree of damage and scattering, resulting in economic losses, and the need to collect the fruit again, further prolonging the working hours. [0003] At present, simple harvesting tools also appear on the market, and m...

Problems solved by technology

[0004] The published patent CN 201310495930.4 discloses an electric palm tree picking machine, which only cuts off the leaves or fruit stalks, and the fruit still falls on the ground, and the fruit needs to be collected again, which cannot be harvested and collected at the same time. Falling off, causing economic loss, the improvement of work efficiency is not obvious

[0005] Published patent CN 201210096608.X discloses a fruit picking executive device. Its chain saw form is not suitable for cutting fibrous palm leaves and hidden fruit stalks, and it is easy to damage other immature fruits and leaves. The position of the clamping device cannot be clamped. Holds oil palm fruit and interferes with cutting oil palm leaves

[0006] The published patent CN 201610893205.6 discloses a knife and fruit collection tool, which will pierce the leaves when cutting the leaves and cause the leaf hooking phenomenon. Because the palm leaves are extremely tough, the leaves can only be removed by putting down the device, which reduces the Picking efficiency, can not effectively adapt to different sizes of fruit
