Dry land crop direct seeding machine

Abstract

The invention discloses a dry land crop direct seeding machine. The dry land crop direct seeding machine comprises a seedbed finishing device, a soil covering device arranged on one side of the seedbed finishing device, a seed discharging device arranged on one side of the soil covering device and a power device arranged above the seedbed finishing device. According to the dry land crop direct seeding machine, the seedbed finishing device is used for smashing soil blocks, stone blocks are discharged to the two sides, a seedbed is leveled, a mulching film drip irrigation belt is laid on the seedbed, and pipe laying, film laying and later seeding are synchronously carried out; the soil covering device collects the stone blocks and discharges the stone blocks to a mulching film; and the seeddischarging device punctures the mulching film and discharges seeds to soil on the ground through cooperation of an air cylinder, a duckbilled barrel and a duckbilled cover. The seedbed finishing device is used for smashing the soil blocks and discharging the stone blocks to level the seedbed, the mulching film drip irrigation belt is laid on the seedbed, pipe laying, film laying and later seedingare synchronously carried out, and therefore the advantages of being high in operation efficiency, good in seeding and film laying effect and the like are achieved.

Description

technical field [0001] The invention specifically relates to a dryland crop direct seeding machine. Background technique [0002] Rice is the food crop with the highest yield, the largest planting area and the largest total output in my country. According to 2016 statistics, my country's rice planting area accounts for 32% of the country's grain, and the total output accounts for 42% of the country's grain. The average yield of rice is 6.89 tons / Hectares, the average yield ranks among the top in the world, and occupies a pivotal position in my country's agricultural production. [0003] With the advancement of agricultural mechanization, more and more rice seeding machines have appeared and used, but there is still a lack of multi-functional and modern rice seeding machines. The development of modern rice seeding machines is an important part of agricultural modernization. [0004] However, the existing rice direct seeding machines have the following defects: poor and unsta...

AI Technical Summary

Problems solved by technology

[0004] However, the existing rice direct seeding machines have the following defects, that is, the seeding accuracy is poor and unstable; the duckbill does not open / block when encountering hard objects, resulting in missed sowing and reseeding; the duckbill tear film produces elastic deformation and rebounds after leaving the soil, covering the rice seeds , sowing misplaced; the thickness of the covering soil is unstable; the hole spacing cannot be adjusted, etc.
