Paddy rice hole direct sowing machine

Abstract

The invention provides a paddy rice hole direct sowing machine which comprises a driving mechanism, wherein a sowing mechanism is in traction connection with the tail end of the driving mechanism, the sowing mechanism comprises a sliding plate, a seed box and a seed metering device, the seed metering device is transversely arranged on the sliding plate, a seed inlet is formed in the top of the seed metering device, the seed box is fixedly connected above the seed inlet, a seed metering shaft is arranged in the seed metering device in a penetrating mode, a seed metering wheel is connected to the middle of the seed metering shaft in a sleeving manner and can rotate along with the seed metering shaft, indents capable of being opened and closed are concavely formed on the shaft wall of the seed metering wheel, and a preset gap is reserved between the seed metering device and the seed metering wheel, so that damage to seeds caused by a shearing effect formed between the rotation of the seed metering wheel and the structure of the seed metering device is avoided, and the germination rate is increased; and the indents on the seed metering wheel are automatically switched in opening and closing states only at a specified position, therefore, seeds are limited and protected in the transportation process of the seeds, the seeds are prevented from moving along a gap between the seed metering device and the seed metering wheel under the action of gravity, the high precision of the sowing effect is ensured, and the paddy rice hole direct sowing machine has a good development prospect.

Description

Technical field [0001] The present invention relates to the field of agricultural machinery, and is specific to a rice pole live. Background technique [0002] Agricultural machinery refers to the various machines used in crop planting and animal husbandry production, as well as agricultural, livestock products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil farming machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery. The seeder is a planting machine with a crop seed as a sowing object. For a certain type or a crop, often crowns based on crop species, such as cereal strokes, corn, cotton seeders, pasture spreadors, etc. [0003] The rice residential shift is sluched by the slide structure of the taid traction, and the crackler on the sk...

Problems solved by technology

[0003] The rice hole direct seeding machine grooves the land through the sliding plate structure pulled by the tail end, and the seed metering device on the sliding plate performs rotary seeding operation on the seeds in the seed box through the recessed holes on the surface of the internal seeding wheel, so as to realize the seed spacing Quantitative sowing is carried out, but the seeds in the socket are easily squeezed or sheared due to the relative movement between the seeding wheel and the seeding device when the seeding wheel of the traditional rice hole direct seeding machine rotates, resulting in damage to the seeds , affects the germination rate of seeds. Some direct seeding machines can reduce the occurrence of seed damage to a large extent by leaving a small gap between the seed meter and the seed wheel, but a small amount of seeds will move through the gap. There is a deviation between the release time of the seeds and the number of seeds, which leads to a decrease in the quantitative accuracy of the sowing distance
