Telescopic Drum Type Gorgon Grain Grading Device

Abstract

The invention discloses a telescopic drum type gorgon grain classification device, comprising a transmission shaft rotatably arranged on an installation platform, a classification drum is arranged on the transmission shaft, and the classification drum is composed of two installation discs, a plurality of connecting rods and a plurality of telescopic rods. Two installation discs are slidably sleeved on the transmission shaft, each installation disc is provided with a group of connecting rod assemblies, the outer ends of several connecting rods of each group of connecting rod assemblies are respectively hinged with the installation disk, and the inner ends of several connecting rods of the two groups of connecting rod assemblies are respectively hinged. The ends are respectively connected by a number of telescopic rods, and the two ends of each telescopic rod are hinged with the corresponding two connecting rods; the transmission shaft is fixedly sleeved with a support plate, and a number of support rods are evenly distributed on the support plate along the circumferential direction, and the middle section of the telescopic rod It is embedded in the adjusting through groove of the support rod; pushes the mounting plate to move left and right, thereby driving several telescopic rods to expand and contract in the radial direction to realize the adjustment of the size of the grading gap. The invention has the advantages that the high-efficiency grading of different grades of Gorgon grains can be realized and the stepless adjustment of the grading parameters can be realized.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a telescopic drum type Gorgon grain grading device. Background technique [0002] my country has a long history of artificially planting Gorgon, and it is widely distributed. It is mostly cultivated in lakes, ponds and beaches. At present, the main producing 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 by grade and shelled in the mechanized production process, they need to be graded and screened. Size grade kernels, while removing underfilled kernels, small kernels and debris. At present, the grading of Gorgon seeds usually adopts a screen or a screening device with a fixed screen. The different sizes of grains are determined by the shape and size...

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
