Precise seeding mechanism of rice seeding machine

Abstract

A precise seeding mechanism of a rice seeding machine is characterized by comprising a machine frame, wherein a seeding conveying belt is arranged in the machine frame, a seeding support and an inclined support are arranged on the machine frame, a storage hopper and an air blowing device are arranged on the seeding support, and an automatic feeding control device is arranged on the outer wall of the storage hopper; the automatic feeding control device comprises a material falling port at the bottom of the storage hopper, a material blocking air cylinder and a material blocking plate, wherein the material blocking air cylinder and the material blocking plate are arranged on the front side of the storage hopper, a piston rod of the material blocking air cylinder is connected with the material blocking plate, and the material blocking plate is in contact with the material falling port; the air blowing device comprises an air blowing support which is fixed to the seeding support, air blowing pipes are arranged on the air blowing support, one end of each air blowing pipe is connected with an air pump, and air blowing nozzles are arranged on each air blowing pipe; and the inclined support is provided with a seeding roller, a feeding hopper, a receiving hopper and a vibrating device, seed suction holes are formed in the seeding roller, and each two seed suction holes form a group, seeding rotating shafts are arranged at the two ends of the seeding roller, the vibrating device comprises a vibrating bracket which is fixedly connected with the inclined support, and a vibration machine is arranged in a vibration outer cover which is arranged on the vibrating bracket, and a connecting plate is arranged on the outer wall of the rear side of the feeding hopper and is connected with the vibrating outer cover.

Description

technical field [0001] The invention relates to a rice planter, in particular to a precision sowing mechanism of the rice planter. Background technique [0002] The key to the mechanization of rice production is mechanization of planting. One of the main methods of mechanization of rice seeds is rice machine transplanting. The key to the success of machine transplanting is seedling raising. Usually rice machine transplanting adopts the sowing line to sow. Most of the rice sowing lines are fully automatic seeders. Fast, high efficiency, labor-saving. The sowing mechanism of the existing rice seeder adopts a crawler-type seed conveyor belt for sowing, and the amount of seeds used is large, and it is impossible to realize precise control of the amount of sown seeds. [0003] Hybrid rice accounts for about 55% of the rice area in my country, and the area of ​​machine-transplanted rice seedlings in rice production has accounted for about 40% of the area. Due to the large amoun...

AI Technical Summary

Problems solved by technology

If the sowing amount of hybrid rice machine transplanting is too high, its growth advantage will not be brought into play, and the cost of hybrid rice seeds will increase due to the high price.

If the amount of sowing decreases, the hybrid rice will not be able to form blankets, cannot be transplanted by machine, and the rate of missed seedlings will increase, and seedlings will need to be replenished, which will increase labor costs.

There is no breakthrough in hybrid rice mechanical transplanting technology, resulting in the development of random transplanting technology and the expansion of the area. Farmers shift from hybrid rice to conventional rice, which affects the stability and increase of my country's total rice production.
