Telescopic drum type gordon euryale seed grading device

Abstract

The invention discloses a telescopic drum type gordon euryale seed grading device which comprises a transmission shaft rotationally arranged on a mounting table, and a grading drum is arranged on thetransmission shaft. The grading drum is composed of two mounting discs, a plurality of connecting rods and a plurality of telescopic rods, the two mounting discs are arranged on the transmission shaftin a sliding and sleeving mode, and each mounting disc is provided with a connecting rod assembly. The outer ends of the multiple connecting rods of each connecting rod assembly are hinged to the corresponding mounting disc, the inner ends of the multiple connecting rods of the two connecting rod assemblies are connected through the multiple telescopic rods, and the two ends of each telescopic rod are hinged to the two corresponding connecting rods respectively. The transmission shaft is fixedly sleeved with a supporting disc, a plurality of supporting rods are evenly distributed on the supporting disc in the circumferential direction, and the middle sections of the telescopic rods are embedded into adjusting through grooves of the supporting rods. The mounting discs are pushed to move left and right to drive the multiple telescopic rods to stretch out and draw back in the radial direction, and grading gap adjustment is achieved. The telescopic drum type gordon euryale seed grading device has the advantages that gordon euryale seeds of different grades can be efficiently graded, and stepless adjustment of grading parameters can be achieved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a telescopic roller type Gorgon seed grading device. Background technique [0002] Gorgon has a long history of artificial cultivation in my country, and its distribution is wide. It is mostly cultivated in lakes, ponds and beaches. At present, the main production areas include Jiangsu, Shandong, Hunan, Hubei, Anhui and other provinces. Gorgon has high nutritional, health and economic value, and is a major export agricultural product in my country. Gorgon seeds are generally round shelled seeds of different sizes. In order to be sold according to grades and shelled in the mechanized production process in the later stage, they need to be graded and screened. The Gorgon seeds are graded according to their size, and the different sizes are screened out. Size-level kernels, while removing unfulfilled kernels, small kernels and sundries. At present, gorgon seeds are generally c...

AI Technical Summary

Problems solved by technology

At present, gorgon seeds are generally classified using a screen or a screening device with a fixed screen. The shape and size of the sieve are used to separate the grains of different sizes. If the grains of different sizes need to be separated during the classification process, they need to be replaced according to requirements. For grading sieves with different apertures, the installation and disassembly of the sieves will increase the intensity of the grading work and reduce the sorting efficiency. At the same time, the size range of the sorting size is also affected by the size parameters of the sorting sieve. The size range of Gorgon seed sorting is limited. And the flexibility of adjustment is poor, which affects the subsequent mechanized treatment of Gorgon seeds
