Potato harvesting soil removing device for sticky land

Abstract

The invention provides a potato harvesting soil removing device for a sticky land for solving the problem of low soil removal degree caused by the fact that an existing potato harvesting machine is not suitable for the sticky land. The device comprises a conveyor belt, a hot air drying assembly and a brush assembly, wherein the hot air drying assembly is arranged near an feeding end of the conveyor belt, and the output temperature of the hot air drying assembly is 30-60 DEG C; the hot air drying assembly comprises a groove-shaped shell, a plurality of heating pipes, a draught fan and a temperature control assembly, wherein the a groove of the groove-shaped shell faces the conveyor belt, the heating pipes are arranged at the inner portion of the groove bottom of the groove-shaped shell, thedraught fan is arranged at the inner portion of the groove bottom of the groove-shaped shell, and the temperature control assembly is used for measuring the temperature of the heating pipes; the draught fan is arranged on the groove bottom of the groove-shaped shell and above the heating pipes; the opposite sides of the groove wall of the groove-shaped shell are both provided with a plurality ofexhaust ports used for heating clay-carried potatoes at 30-60 DEG C. The potato harvesting soil removing device for the sticky land has a simple structure and greatly increases the effect of soil removal.

Description

technical field [0001] The present invention relates to a potato collection device, in particular to a heating type potato harvesting and soil removal device for clay soil. The present invention is used in conjunction with a potato harvester when harvesting potatoes. After heating, use a brush to remove soil. Background technique [0002] Potatoes, also known as yams, are native to the alpine regions of Peru and Chile. They were introduced to China by the Dutch in the middle of the 17th century. They have been cultivated in my country for more than 300 years. Potato tubers contain 8-29% starch, protein, minerals and vitamins and other nutrients. They have good yield and wide adaptability, and have gradually become an important food, vegetable, feed and industrial raw material for human beings. [0003] With the development of agricultural mechanization, there are currently many models of potato harvesting equipment, each with its own advantages and disadvantages, but the co...
