Drum type seed coating machine

Abstract

The invention relates to a seed coating machine, in particular to a drum type seed coating machine. The drum type seed coating machine comprises a machine frame, a material feeding hopper, a premixingbox, a pesticide supply system, a stirring drum and a drum driver, wherein the material feeding hopper is communicated with the inlet end of the premixing box and is fixedly arranged at the top partof the machine frame, the outlet end of the premixing box is communicated with the inlet end of the stirring drum which is arranged on the machine frame and is rotated around the axis, and the pesticide supply system is communicated with the interior of the premixing box. The drum type seed coating machine is characterized in that the output end of the drum driver is connected with an active beltwheel, and a driven belt wheel is fixedly arranged on the stirring drum. By adopting the technical scheme, the drum type seed coating machine has the advantages that the drum driver directly drives the stirring drum to rotate through a driving belt, rollers only reach the supporting function, the labor is clearly divided, the friction coefficient of the driving belt is large, the power transfer efficiency is high, the friction coefficient between the rollers and the stirring drum is small, the energy loss is reduced, and the stability in movement is improved; the stirring drum is stably and reliably rotated, the slippery is avoided, the seeds are uniformly coated, and the firmness is high.

Description

technical field [0001] The present application relates to a seed coating machine, in particular to a drum type seed coating machine. Background technique [0002] Seed coating is a key link in the current crops that must be treated with seed medicines before sowing, because the seed coating contains nutrients such as insect control and disease treatment drugs and auxin, and the quality of the seed coating directly affects the growth of crops. and yield; therefore, the mechanical properties of seed coating are particularly important. [0003] Chinese Utility Model Patent, Patent No. 200920164671.6 discloses a drum-type seed coating machine; it has the following defects: (1) the drum drive directly gives the power to the rollers, and the rotation of the mixing drums is achieved by the rotation of the rollers. However, due to The roller needs to support the mixing drum, and its cooperation must be a smooth linear contact, resulting in a large slip coefficient of the mixing dru...

[0003] Chinese Utility Model Patent, Patent No. 200920164671.6 discloses a drum-type seed coating machine; it has the following defects: (1) the drum drive directly gives the power to the rollers, and the rotation of the mixing drums is achieved by the rotation of the rollers. However, due to The roller needs to support the mixing drum, and its cooperation must be a smooth linear contact, resulting in a large slip coefficient of the mixing drum, uneven speed, and even slipping and stalling, which seriously affects the coating quality; (2) During the coating process, the drug supply system Toxic gas will be produced in the premixing box and mixing drum, and these gases will directly volatilize and pollute the air and working environment
