Abstract

The invention provides a soil-ejecting seeding mechanism for a hole-making seeder, and belongs to the field of soil-ejecting seeding mechanisms. Comprises a soil ejection rod, a seed conveying sliding block, a guide block, a sliding sleeve, a guide rod, a traveling wheel, a seeding pipe, a hole making nozzle, a hole nozzle cover, a return spring, a damping spring, a track block, a seed conveying cavity and a seed limiting wheel; the soil-ejecting rod, the seed-conveying sliding block and the guide block are arranged in the seeding pipe, and the sliding sleeve, the reset spring and the damping spring are arranged outside the seeding pipe; the guide rod with the traveling wheels at two ends is assembled with the seed conveying sliding block; the traveling wheel travels along the track block to drive the seed conveying sliding block to move in the seeding pipe, so that the soil ejecting rod stretches. When the hole making nozzle is buried and the hole nozzle cover is opened, the soil bouncing rod pops out soil in the hole making nozzle, seeds are buried, and leak-proof seeding is achieved. The soil-ejecting rod, the seeding pipe and the seeding hub are changed in a set, different crops can be sown, and the multifunction of one machine is realized.

Description

Soil-ejecting seeding mechanism for hole-making seeder

[ technical field ] A method for producing a semiconductor device

The invention relates to a soil-bouncing seeding mechanism for a hole-making seeder, belongs to the field of soil-bouncing seeding mechanisms of seeders, and particularly relates to a soil-bouncing seeding mechanism for a hole-making seeder.

[ background of the invention ]

The hole making mechanism of the existing hole making seeder is easy to cause missed seeding due to the structural design reason, and one machine can only seed 1-2 crops, so the use of farmers is very inconvenient. The soil-ejecting sowing mechanism for the hole-making sowing machine is mounted on the hole-making sowing machine, can ensure that the hole-making sowing machine has no missed sowing, has multiple purposes, can be used for sowing soybeans, corns, broomcorn millet, wheat, millet, cowpeas, mung beans and peas, can be used for performing mound sowing planting on vegetables such as kidney beans, hot peppers, Chinese cabbages, radishes, onions and the like, and is particularly suitable for mound sowing planting on grains and vegetables of farmers.

The invention relates to a soil-bouncing seeding mechanism for a hole-making seeder, which aims to be arranged on the hole-making seeder, can realize multiple purposes of one machine of the hole-making seeder, can well perform seeding without damaging seeds or leaking seedlings by the hole-making seeder, and achieves the purpose of convenient use for farmers.

The invention is realized by the following steps:

a soil-ejecting seeding mechanism for a hole-making seeder belongs to the field of soil-ejecting seeding mechanisms of seeders. Comprises a soil ejection rod, a seed conveying sliding block, a guide block, a sliding sleeve, a guide rod, a guide sleeve, a traveling wheel, a seeding pipe, a seeding hub, a hole making nozzle, a hole nozzle cover, a return spring, a damping spring and a track block;

the soil-ejecting rod and the seed-conveying sliding block are arranged inside the sowing pipe, and the sliding sleeve is arranged outside the sowing pipe; the guide rod is assembled by a guide block and a seed conveying sliding block, and travelling wheels are arranged at two ends of the guide rod;

the guide block and the sliding sleeve are assembled into a whole and are arranged in the longitudinal groove of the seeding pipe, and the reset spring and the damping spring are arranged outside the seeding pipe and at two ends of the sliding sleeve;

the travelling wheel drives the seed conveying sliding block to reciprocate in the seeding pipe to drive the soil ejection rod to move telescopically in the process of travelling along the track block; when the hole making nozzle is buried and the hole making nozzle cover is opened, the soil bouncing rod stretches out to bounce soil in the hole making nozzle, and seeds smoothly enter the soil, so that the anti-blocking hole making seeding is realized.

[ detailed description ] according to the present embodiment

The invention is realized in such a way that the earth-ejecting rod 3, the seed-conveying sliding block 8 and the guide block 14 are fixed into a whole and are arranged in the seeding tube 2, the sliding sleeve 9, the reset spring 7, the damping spring 13 and the fixed sleeve 5 are arranged outside the seeding tube, and the guide rod 17, the guide sleeve 18 and the walking wheel 10 are assembled with the sliding sleeve 9 and the seed-conveying sliding block 8 into a whole; the track block 11 and the fixed plate 12 are fixed into a whole, and the walking wheel 10 drives the seed conveying sliding block 8 to reciprocate in the seeding pipe 2 in the walking process along the track block 11 and drives the earth ejecting rod 3 to move telescopically; when the hole making nozzle of the seeding pipe 2 is buried and the hole making nozzle cover 1 is opened, the soil bouncing rod 3 stretches out to bounce soil in the hole making nozzle, so that seeds smoothly enter the soil, and thus, the anti-blocking hole making seeding is realized; after the hole-making seeder is installed, different grains and vegetables can be sowed by only replacing the sowing pipe 2, the soil-bouncing rod 3 and the sowing hub 6 in a set.
