A rice seeding machine

Abstract

The invention provides a rice hole direct seeding machine, which comprises a driving mechanism, the tail end of the driving mechanism is connected with a seeding mechanism, and the seeding mechanism comprises a sliding plate, a seed box and a seed metering device. The seed metering device is horizontally arranged on the sliding plate, and the seed metering device There is a seed inlet on the top of the machine, a seed box is fixedly connected above the seed inlet, a seed metering shaft is penetrated inside the seed metering device, and a seed metering wheel is sleeved in the middle of the seed metering shaft. The shaft rotates, the shaft wall of the seed metering wheel is recessed with a socket that can be opened and closed, and there is a preset gap between the seed metering device and the seed metering wheel, which avoids the rotation of the seed metering wheel and the structure of the seed metering device. Intermittent shearing effect will damage the seeds and improve the germination rate. The sockets on the seeding wheel automatically switch the opening and closing state only at the designated position, and limit the seeds during the transportation of the seeds to prevent the seeds from being under gravity. Under the action, it moves along the gap between the seed metering device and the seed metering wheel, which ensures the high precision of the seeding effect and has a good development prospect.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a rice seeding machine. Background technique [0002] Agricultural machinery refers to various machinery used in the production process of crop planting and animal husbandry, as well as in the initial processing and processing of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc. A planter is a planting machine that uses crop seeds as the sowing object. The seeder used for a certain type or a certain crop is often named with the name of the crop type, such as grain drill, corn hole seeder, cotton seeder, forage sp...

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
