Description

Electric transmission type electric air suction seed metering device

technical field

The utility model belongs to the field of agricultural machinery, in particular to an air suction seed metering device for agricultural seeders.

Background technique

The seed metering device is the core component of the seeder. The seed metering status of the seed metering device directly affects the sowing operation, and plays a decisive role and significance in agricultural production. Mainly to the following two points to summarize the present situation of existing sowing implement. 1. At present, the seeding transmission of the existing seeder is driven by the ground wheel. Its shortcoming is that the ground wheel has large resistance and is easy to slip. Conservation tillage does not plow after harvest, there are stubble in the field, straw and weeds on the soil surface, these factors will weaken the adhesion of the ground wheel, increase the probability of the ground wheel slipping, and thus affect the quality of sowing. With the wide application of mechanical agricultural machinery,

Its more deficiencies are also becoming more and more obvious. Mechanical control, transmission, and speed change are mostly realized by steel parts such as joysticks, chains, and gear sets, which require a large operating space and large operating force.

The mechanical vibration is large, there is more noise, oil lubrication is often used, the sealing requirements are high, and the operating environment is poor. Some components are prone to heat and have poor reliability, requiring regular maintenance. 2. The existing air-suction seed metering device needs additional power (large fan) to achieve sowing, the fan needs mechanical power to drive, and the transmission force is basically realized by the rear output of the tractor, so a series of transmission accessories are required To complete, resulting in complicated machine tool structure, high production cost, difficult to operate and so on. At present, some fans of air suction seeders are driven by hydraulic motors. The domestic hydraulic motor technology is not very mature, and there are some unstable factors, while the foreign hydraulic motor technology is mature, but the price is expensive, which is not suitable for the current stage of our country. The actual situation of agricultural production.

Therefore, in view of the above two points, we can see that our country urgently needs a new type of technology and products to solve the above problems.
