Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fruit picking, in particular to a fruit sorting and cutting device of a fruit picking robot. Background Art
[0002] Since the fruits on the outer treetops are scattered and the spatial distribution of fruits at the treetops lacks regularity, the picking mode of existing fruit picking robots is basically to pick single fruits according to the fruit growth distribution. The picking robots need to frequently identify and adjust their posture, which makes the picking efficiency of the picking robots low.
[0003] In addition to changing the fruit tree cultivation model agronomically to make the fruit distribution neat and orderly, compared with the growth distribution of field crops, the fruit distribution in unstructured orchards lacks large-scale continuity and symmetry, which makes it difficult to complete fruit picking using the field agricultural machinery model.
[0004] The core reason for the low efficiency of these traditional robots is that the fruits are too scattered on the branches, and the distribution symmetry is not strong, so the picking robot arm needs to repeatedly adjust the position and posture information according to the target fruit distribution to complete the picking of the fruits, resulting in a slow picking speed. The fruits growing on the outer treetops are actually distributed more scattered, and the positions of the fruit distribution are still very variable. If the fruits distributed on the outer treetops can be sorted in an orderly manner and the fruit sorting and rearrangement can be achieved, the picking adaptability of the end effector of the picking robot will be greatly improved. When the picking robot picks the fruit, it often uses a single-action cutting tool to directly cut the fruit on the fruiting branch group, so as to complete the fruit picking process without destroying the fruit. However, due to the supply of nutrients and water, the xylem and phloem of the fruiting branches of normal fruit trees have strong toughness, resulting in the low efficiency of the single-action cutting tool on the general picking robot to cut the branches.

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] See also Figures 1 to 6 In the embodiment of the utility model, the fruit picking robot has a fruit sorting and cutting device, the main function of which is to sort and rearrange the scattered fruits in a combing manner, and finally realize the integrated task of fruit sorting and cutting, including a slide rail 100, a fruit sorting and separating mechanism 200 is slidably connected inside the slide rail 100, and the fruit sorting and separating mechanism 200 is equipped with an adjusting mechanism 300 and a cutting mechanism 400.
[0029] The fruit sorting and separation mechanism 200 includes a plurality of sorting comb teeth 210, which can effectively separate the fruit from the fruiting branch group through the combing action, so as to sort and rearrange the scattered fruits on the treetops, and the top ends of the plurality of sorting comb teeth 210 are slidably connected to the inside of the slide rail 100, and the bottom of one side of the plurality of sorting comb teeth 210 is provided with a rectangular groove 211, and the inside of the plurality of rectangular grooves 211 is provided with a one-way fruit feeding rotating plate 220, and one end of the plurality of one-way fruit feeding rotating plates 220 is rotatably connected to the inside of the adjacent rectangular groove 211, and one end of the plurality of one-way fruit feeding rotating plates 220 is provided with a torsion spring 221, and one end of the plurality of torsion springs 221 is fixedly connected to one side of the adjacent one-way fruit feeding rotating plates 220, and the one-way fruit feeding rotating plates realize the one-way entry of the fruit from the front end of the comb teeth, ensuring that the fruit can be concentrated on the comb tooth surface after the one-way entry, and the other end is fixedly connected to an inner wall of the adjacent rectangular groove 211, and the bottom of the other side of the plurality of sorting comb teeth 210 is fixedly connected to the front end branching plate 230 of the comb teeth.
[0030] Specifically, the fruit sorting and cutting device is connected to the mechanical arm of the picking robot through the connection interface, and the mechanical arm is controlled to adjust its position so that the mechanical arm drives the slide rail 100 and the multiple sorting comb teeth 210 thereon to move.
