Precise seed-attaching no-tillage seeder on paddy mulching film

Abstract

The invention provides a precise seed-attaching no-tillage seeder on a paddy mulching film. The precise seed-attaching no-tillage seeder comprises a PLC (Programmable Logic Controller), a man-machine interaction unit, a rack, a glue spraying unit, a notch unit, a seed attaching unit, a residual seed recycling box, a cam carrier roller, a tensioning/reversing carrier roller unit, a mulching film carrier roller, a power film clamping unit, two tensioning carrier rollers, a film winding carrier roller, a displacement sensor and three frequency conversion motors, wherein the tensioning/reversing carrier roller unit, the mulching film carrier roller, the power film clamping unit, the two tensioning carrier rollers and the film winding carrier roller are respectively arranged at the two sides of the rack through bearings; power is respectively supplied to the power film clamping unit, the cam carrier roller and the film winding carrier roller by the three frequency conversion motors; the mulching film is wound on the mulching film carrier roller; and the mulching film sequentially winds around the first tensioning carrier roller, the cam carrier roller, the tensioning/reversing carrier roller unit, the power film clamping unit and the second carrier roller, and is finally wound by the film winding carrier roller. The machine disclosed by the invention is precise in positioning and accurate in sowing on the mulching film and is suitable for large-area mechanical work of direct sowing production of rice.

[0002] In traditional rice planting, seedling cultivation and transplanting have always been the key link that restricts yield and quality, and the production procedures are complicated

One is the conventional rice seedling cultivation and transplanting cultivation, which is a kind of tiring and hard work in the countryside. When raising seedlings, weak seedlings and diseased seedlings are prone to appear due to the influence of the climate. Especially when transplanting rice seedlings, the labor intensity is very high, which is the biggest burden for farmers.

The second is that even if it is ordinary direct-seeded film-covered rice, it needs to be broadcast first, then covered with film, and seedlings need to be released after emergence. If the seedlings are not released in time, it is easy to cause phenomena such as burning buds. Then sowing can only be done manually with a small hole seeder, because the use of machinery to sow after film covering can easily cause damage to the film, high labor intensity, and low operating efficiency. The development of mechanization has opened a new chapter; the third is that for a long time, the prerequisite for rice planting is to have fixed irrigation water sources such as rivers. Some low-lying lands prone to waterlogging and some medium and low-yielding fields can only grow soybeans and corn due to the lack of irrigation water sources. and other crops

Fifth, due to conventional rice planting, it grows and develops almost under flooding conditions during the growth period, especially well-irrigated rice, which is greatly affected by low temperature and cold, resulting in a lag in the growth period, which affects the improvement of yield and quality, and high production costs , the benefit is not good
