Problems solved by technology

Moreover, because the litchi skin is thin and tender, if the vibratory picking method is adopted, the fruit will quickly fall to the ground and cause the fruit to burst, increasing the damage rate of the fruit
The picking robot mainly has the following problems: ①The recognition rate and positioning accuracy of the fruit are not high; ②The fruit picking is for a single fruit, and the average picking cycle is long; ③The cost is high
For lychees, the height of fruit trees is generally 3 to 6 meters, and the fruits are scattered and scattered. Therefore, there are bound to be high requirements for the operating range, calculation speed, and execution speed of the picking robot. However, the performance of the picking robot cannot meet these requirements at present.

Embodiment

[0024] A kind of litchi picking flexible combing and shearing mechanism of this embodiment, its structure is as follows: figure 1 As shown, it includes a toothed plate 1, a branch assembly, a sorting assembly and a cutting assembly. The branch assembly includes a plurality of conical rubber blocks 2, and each conical rubber block is respectively arranged on each tooth 1-1 on the toothed plate. At the end, a sorting assembly is provided in the middle of any two adjacent teeth on the toothed plate, and a cutting assembly is provided at the root of any two adjacent teeth on the toothed plate. Wherein, the function of the branching component is to separate the lychee branches and guide the branches into the tooth gaps of the toothed plates without damaging the lychee fruit, and the conical rubber block can be selected from a hard elastic material.

[0025] The sorting assembly includes a thin-walled baffle 3, a return spring 4 and a limit block 5. One end of the thin-walled baffle...

Embodiment 2

[0032] In this embodiment, a rolling combing and shearing device with a flexible combing and shearing mechanism for litchi picking has a structure such as figure 2 Shown, comprise flexible combing and shearing mechanism (flexible combing and shearing mechanism is the flexible combing and shearing mechanism described in embodiment 1, and its specific structure is as follows figure 1 As shown), drum 8 and mounting support 9, at least one mounting support is provided on the outer surface of the drum, and the flexible combing and shearing mechanism is fixed on the outer surface of the drum through the mounting support; the radial section of the mounting support is "herringbone" , the bottom plate of the mounting support is locked and connected with the side of the drum through bolts, and the toothed plate in the flexible combing mechanism is fixedly connected with the top plate of the mounting support through bolts.

[0033] In this embodiment, as a preferred solution, there are ...

Abstract

The invention discloses a litchi picking flexible combing-shearing mechanism and a rolling combing-shearing device. The flexible combing-shearing mechanism comprises a tooth-shaped plate, branch separating components, a sorting component and cutting components, wherein the branching components comprise a plurality of tapered rubber blocks, all the tapered rubber blocks are arranged at the tail ends of all teeth on the tooth-shaped plate respectively, a sorting component is arranged in the middle of a tooth gap between any two adjacent teeth on the tooth-shaped plate, and a cutting component is arranged at a tooth root position of any two adjacent teeth on the tooth-shaped plate. The rolling combing-shearing device is provided with the litchi picking flexible combing-shearing mechanism. According to the litchi picking flexible combing-shearing mechanism and the rolling combing-shearing device, braches with fruits and branches without fruits of litchis can be separated, and effective shear can only be carried out on the branches with the fruits.

Description

technical field [0001] The invention relates to the field of fruit picking machinery, in particular to a flexible combing and shearing mechanism for picking litchis and a rolling combing and shearing device. Background technique [0002] Litchi is a characteristic fruit in the south. It has a history of more than 2,000 years. Litchi is bright purple in color, thin and flat, with delicious flesh and rich nutrition. It is known as the "king of fruits". However, currently my country's lychee picking is completely dependent on manual picking, which seriously restricts the development of its production. The specific manifestations are: the acceleration of urbanization, the young and strong labor force entering the city to work, the shortage of labor force, making it difficult to find workers, high labor costs, increasing the harvest cost of lychees, and reducing the market competitiveness of lychees; Generally, picking is carried out by climbing trees or using ladders. The worki...
