Problems solved by technology

This kind of fruit picking device actually picks fruit by brushing off, which has a high picking rate, but at the same time, the pods have a high rate of stalks, and there are many broken seedlings and branches, which affect the harvest quality.
However, the high rate of fruit pods with stalks leads to the need to spend more manpower to manually remove the fruit stalks on the fruit pods, and the number of broken seedlings and branches increases the separation of peanut fruits and seedlings in the later stage of harvest.
The above problems have become the technical bottleneck of the semi-feeding peanut combine harvester

Embodiment 1

[0016] The half-feeding peanut harvesting device of the present embodiment is as image 3 As shown, it is made of a pair of rollers 3, and the two rollers are radially equipped with fruit-picking blades 5 that are distributed in different phases at intervals, that is, the fruit-picking blades 5 of the two rollers are mutually staggered. The two ends of the roller 3 are supported on the roller shaft 1, and the blade fixing seats 2 distributed at intervals extend radially from the outer circle, and each blade fixing seat is equipped with a fruit-picking blade 5 through a fixing bolt 4, and the fruit-picking blade 5 faces away from the roller 3 A circular arc surface that is gradually curved in the direction of rotation, with chamfers at both ends (see figure 2 ).

[0017] When working, the arc-shaped fruit-picking blades have a beating effect on the peanut pods instead of a brushing effect, thus avoiding the shearing effect. Moreover, since the arc-shaped fruit-picking blades...

Embodiment 2

[0019] The half-feed peanut picking device of the present embodiment is as image 3 As shown, the basic structure is the same as that of Embodiment 1, the difference is that the blade fixing seat 2 extending radially from the outer circle of the roller 3 is inclined towards the direction away from the rotation of the roller 3, and the included angle with the radial direction is 30±5° Preferably, the bending direction of the outermost edge of the circular arc fruit picking blade 5 is tangentially coincident with the enveloping circle of the outermost edge of the arc fruit picking blade 5 . Like this, when fruit-picking blade 5 is in contact with branch-shaped seedlings, rhizomes, and fruit stalks, its slapping effect will only cause it to deform, and will not make rhizomes and fruit stalks be cut off. Only then will it produce a more obvious hitting force and "take it off".

[0020] Practice has proved that, after this embodiment is applied to improve the semi-feeding peanut c...

Abstract

The invention relates to a semi-feeding device for harvesting peanuts and picking fruits, belonging to the technical field of agricultural machinery. The device comprises a pair of rollers racially provided with fruit-picking blades in differential phase distribution at intervals; the fruit-picking blades present continuous curved surfaces which gradually bend deviating from the rotary direction of the roller. For the convenient manufacture, the curved surface is in a circular arc shape. The device of the invention not only keeps high picking rate, but also effectively reduces the stem carrying rate of fruit pods and the rates of seedling breaking and root breaking, thus the harvest quality of a semi-feeding peanut combine harvester can be significantly improved.

Description

technical field [0001] The invention relates to a fruit picking device, in particular to a half-fed peanut harvesting and fruit picking device, which belongs to the technical field of agricultural machinery. Background technique [0002] According to the applicant's understanding, the peanut combine harvester mainly has two forms of full feeding and half feeding at present. The full-feed peanut combine harvester has shortcomings such as entanglement of seedlings and vines, high damage rate, unclean separation of fruit and seedlings, and high power consumption, while the half-feed peanut combine harvester can overcome the above shortcomings. At the same time, the half-feed peanut combine The harvesting method does not crush or destroy the seedlings and tendrils, and the harvested seedlings and tendrils can still be used as high-quality feed for animals. In recent years, the semi-feeding peanut combine harvester has become the development trend of the peanut combine harvester...
