A drum classifier with adjustable fruit size screening and its implementation method

Abstract

The invention discloses a drum type classifier with adjustable fruit size screening, which comprises a frame, a fruit feeding device, a drum, an adjustment mechanism, a supporting mechanism, a driving mechanism, a fruit outlet I and a fruit outlet II. The fruit feeding device is fixed on the frame; the drum includes a ring retaining ring at the right end, a cylinder, and a screening cylinder. The annular retaining ring at the right end is connected to the right end of the cylinder through screws. The screening cylinder includes a round rod, an annular retaining ring at the left end, and a spiral blade; The adjustment mechanism includes a rotating cover, a steel wire rope, a tension spring and a set screw. The rotating cover is installed on the cylinder through a threaded pair. One end of the steel wire rope is fixed to the ring retaining ring at the left end, and the other end is connected to the tension spring and the other end of the tension spring is fixed. At the right end of the annular retaining ring, the set screw is installed on the rotating cover; the invention realizes the adjustment by adjusting the relative angle between the rotating cover and the screening cylinder, thereby changing the spiral winding shape of the wire rope, and then changing the size of the screening grid. Grading of fruits of different sizes, simple structure and high working efficiency.

Description

technical field [0001] The invention belongs to the technical field of fruit grading, and in particular relates to a drum-type grading machine with adjustable fruit size screening and an implementation method. Background technique [0002] As we all know, my country has become the world's largest fruit producer. In recent years, with the improvement of people's living standards, the fruit consumption structure has changed, and people's requirements for fruit quality are getting higher and higher. Most of them are classified manually, which is extremely inefficient and wastes manpower. This requires the fruit classifier to have high screening efficiency and high quality. [0003] On the other hand, apples, jujubes and other fruits collected by orchard farmers usually have different sizes and shapes. Even the same fruit tree may produce different sizes and shapes of fruits due to differences in water, light, and regions. big difference. Before the fruit is sold or processed,...

AI Technical Summary

Problems solved by technology

Before the fruit is sold or processed, it is necessary to use the standard of size and shape to carry out grading, so as to facilitate the sale of different grades of fruit with a price tag or be processed into different foods. Although the existing fruit screening device Can effectively solve the problem of fruit screening, improve production efficiency, and save labor costs, but most fruit classifiers have a fixed and non-adjustable grading range, such as the authorized patent "a combined fruit screening device (authorized Notification number: CN207787074U) "The screening effect is single and cannot be adjusted, and the application range in actual production activities is narrow
