Adjustable potatoes harvester

Abstract

The invention provides an adjustable potato lifter. A plowshare (17) is arranged on a plow frame (16), plow arms (18) are connected on the two sides of the machine body (22) fixedly, a depth limiting wheel shaft bracket (20) is provided with a depth limiting wheel (19) raising machine body (22). The distance between a depth limiting wheel (19) and a depth limiting wheel roof beam (11) can be adjusted by a depth limiting wheel adjusting rod (26) to determine the in-earth depth of the plowshare (17). A power output wheel (2) transmits the power to an eccentric shaft belt wheel (8) through a transmission belt (3) and an intermediate belt wheel (6). The shaft end of an eccentricity shaft (9) and a connecting shaft (12) are connected through a sieve oscillating connecting rod (10), and a sieve oscillating arm (13) together with a sieve (15) oscillates forth and back around a sieve oscillating middle shaft (14). In the invention, the plowshare (17) and the sieve (15) are arranged separately, so that the vibration is lightened; the plowshare (17) can be changed separately, the maintenance is convenient, the cost is low; the installation angle of the plow frame (16) can be adjusted, the adaptability is strong; the quality of the harvest is excellent, and the efficiency is high.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a machine for harvesting crop roots. Background technique [0002] Potato is a nutritious, high-yield, easy-to-plant, high-quality and low-cost agricultural product. At present, the domestic market demand is increasing year by year. The potato planting area continues to expand and the output continues to increase. Harvesting potatoes is an important production link. For many years, the vast rural areas have been using traditional backward methods such as manual digging and animal plowing to harvest. Not only is the labor intensity high, the efficiency is low, and the damage rate is high, affecting the quality and the price cannot go up. , especially in alpine regions, due to incomplete and untimely harvesting, a considerable part of the potatoes rotted in the ground, causing losses. With the development of science and technology and the improvement of economic strength, mechanical exca...

AI Technical Summary

Problems solved by technology

Although existing potato digging machines and combine harvesters can achieve the purpose of mechanized potato harvesting, they are bulky, heavy, and costly to use. The plowshare and the sieve are often connected as one, and the position of the plowshare and the machine base where the plowshare is installed is Fixed, the angle of the plow head entering the soil cannot be adjusted. This structure generally has the following problems: First, the plow shovel and the sieve are an integral structure. In the vibration, it is easy to cause structural fatigue damage to the machine body; second, the installation angle of the plow shovel is fixed, and it is difficult to adapt to work in different soil plots. The field can not be pulled, and the versatility is poor; the third is that the plow and shovel are mostly integral structures, and the plow and shovel assembly must be replaced for normal wear or accidental damage, which is not only troublesome, but also wasteful, high in use cost, and heavy economic burden
