Fixed tooth and movable tooth combined step-by-step peanut picking device

Abstract

The invention discloses a fixed tooth and movable tooth combined step-by-step peanut picking device, and belongs to the technical field of peanut harvesting machinery. Comprising fixed teeth, a picking roller, a seedling unloading plate, a sieve plate, a shell and an auger, the two ends of a roller shaft of the picking roller are fixed to a left side plate and a right side plate of the shell through picking roller bearing seats, a row of fixed teeth are arranged below the working front end of the picking roller, each fixed tooth is provided with an arc-shaped working face, and the end, close to the picking roller, of each fixed tooth is tangent to the circumference of the picking roller; the auger is arranged behind the picking roller through an auger bearing seat, a sieve plate is arranged below the auger, and the sieve plate is connected with a seedling unloading plate which is in transition connection with the picking roller and is matched with the auger to form a kinematic pair. The peanut picking process is divided into two steps, the fixed teeth go deep into the earth surface by a certain depth to shovel up peanut plants, then the peanut plants are driven by the picking roller to move upwards, and the picking and pushing process is completed. Peanut plants are unloaded by the seedling unloading plate and then slide into a rear auger.

Description

technical field [0001] The invention belongs to the field of agricultural machinery technology and peanut harvesting machinery technology, and in particular relates to a fixed-moving teeth combined step-by-step peanut picking device. Background technique [0002] Peanut is an important oil crop and economic crop in the world and even in my country. It is also the most competitive agricultural product for export and earns foreign exchange in my country. It has a very high status in China. The perennial planting area of ​​peanuts in my country is 70 million mu, accounting for about 18% of the world's peanut planting area, second only to India and ranking second in the world; the output is 17 million tons, accounting for about 40% of the world's total peanut production, ranking first in the world . In my country's oil crops, the yield of peanuts ranks first, with an oil content as high as 50%. At the same time, peanut meal and straw are high-quality animal feed, which play an i...

Problems solved by technology

Due to the large structure and limited speed of the toothed belt pick-up device, it is difficult to realize wide-width and high-speed pick-up operations

The cam slide type elastic tooth roller pick-up device is not only complicated in structure, but the repeated impact of the roller on the cam plate in the slideway is likely to cause wear and tear of the parts and fatigue damage of the cam plate, and the periodic vibration of the pick-up device reduces the picking stability. Upward movement needs to overcome the friction of the guard plate, and the rebound of the spring teeth off the ground will "hit" the peanut plant. During the picking process, the peanut plant often appears "throwing", "piling" and "rolling". The working resistance is large, Peanut picking loss is serious

In order to improve the performance of the spring-tooth roller peanut picking device, people have invented a series of auxiliary measures, such as installing a "seeding roller", "seeding rolling roller" and "seeding pressing grid" similar to a "grain reel" on the front and upper part of the picking roller. etc., but these measures are limited to dredging the picked-up peanut plants, but have not fundamentally improved the picking-up mechanism, and the effect is not significant
