Abstract

The invention discloses a self-screening type towing and collecting device for grain harvesting based on winnowing. The device comprises a vehicle body, a collecting box, a piston plate, a gas filter,a guide plate and a gas spraying head, wherein a wheel shaft is connected with a penetrating shaft in the interior of the lower end of the vehicle body, a gas suction bin is formed in the inner sideof the vehicle body, the piston plate is arranged on the inner side of the gas suction bin, a hook is welded to the outer side of the right end of the vehicle body, the gas filter is arranged on the outer side of the right end of the vehicle body, a rack is arranged on the inner wall of the right end of the vehicle body, the gas spraying head is connected to the outer side of the rack, and a gas conveying pipe is connected between the gas spraying head and the gas suction bin. According to the self-screening type towing and collecting device for grain harvesting based on winnowing, grains canbe automatically shaken and thrown high in the towing advancing process, tail gas heat generated in the working process of harvesting machinery can be recycled through the negative pressure effect, primary drying can be carried out on the grains while winnowing is achieved, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of grain harvesting, in particular to a winnowing-based self-sieving type grain harvesting trailer collection device. Background technique [0002] Food is an essential source of energy for human beings, and grains are the most important source of food. my country has always been a large agricultural country, and the planting volume of grains ranks among the top in the world. During the ripening season of grains, it is often necessary to use a large amount of agricultural The machinery harvests the grains in time, and the harvesting machinery can separate the grains from the straw, making the subsequent transportation and processing of grain particles more convenient. With the continuous development of science and technology, the working efficiency of grain harvesting machinery is getting higher and higher. In order to collect and transport the harvested grain synchronously, it is necessary to use a trailer co...
