Mechanical clutch for potato harvester

Abstract

The invention discloses a mechanical clutch for a potato harvester. The mechanical clutch comprises a driving shaft, a driven shaft, a connecting sleeve and a control part, wherein the connecting sleeve is connected to the driven shaft through a connecting key; the head part of the connecting sleeve is connected to a claw-shaped structure matched with the tail part of the driving shaft; the control part comprises a main frame, a reset spring and a rotating frame; a limiting ring is arranged on the main frame, and the limiting ring is connected to an outer ring of the driven shaft in a sleevingmode; one end of the reset spring abuts against the right side of the connecting sleeve, and the other end of the reset spring is abutted against the left side of the limiting ring; and the top end of the rotating frame is hinged to the main frame, a waist hole is formed in the middle of the rotating frame, a bolt is connected in the waist hole, the head of the bolt is rotationally connected to the outer wall of the connecting sleeve, a connecting rod is arranged at the bottom of the rotating frame, the connecting rod can slide up and down relative to a sliding groove, and the side wall of the right end of the sliding groove is connected to a pull rod. According to the device, a mechanical structure is used for controlling opening and closing of the clutch, the stability is good, and theservice life is long.

Description

Technical field [0001] The invention relates to a mechanical clutch for a potato harvester. Background technique [0002] Potatoes are widely planted and rich in nutrients. They are known as "underground apples", "diet upstarts" and "top ten popular nutritious and healthy foods". They are the world's fourth largest food crop after corn, wheat and rice. China is one of the countries with the largest potato planting area in the world. And domestic efforts to promote the use of potato staple food, processed into staple food such as steamed bread, noodles, rice noodles, etc., the planting area is gradually expanding. However, the level of mechanization of potato production in China is low, and the international competitiveness is poor. It is far from being able to meet market demand. [0003] In response to the above problems, various types of potato harvesters have emerged, and the clutch structure in potato harvesters, as the supreme guarantee of safety, has also attracted more and ...

AI Technical Summary

Problems solved by technology

However, the level of mechanization of potato production in China is low, and the international competitiveness is poor. It is far from meeting the market demand.

[0003] In response to the above problems, various types of potato harvesters have emerged, and the clutch structure in potato harvesters, as the highest guarantee of safety, has attracted more and more attention. Traditional friction couplings are expensive and cannot be used for a long time. Running in muddy water, the purely mechanical clutch structure has attracted more and more attention due to its low cost, good stability, and easy operation and maintenance.
