Description

Rice precision hole sowing method

Technical Field

The invention belongs to the technical field of seeding in agricultural planting, and particularly relates to a rice precision hole seeding method.

Background

The direct seeding cultivation technique of rice is a cultivation method for directly seeding rice seeds in a field by mechanical equipment, and has gradually become an important cultivation mode for rice production due to the advantages of simplified process, labor reduction, high yield, high efficiency and the like. Many mechanical devices developed for this technology, such as the devices disclosed in CN104285551A and the like, which mainly have a pure mechanical structure, are conventional, and the principle can be mainly classified into two types: mechanically and pneumatically. However, with the further improvement of the requirements for yield, sowing technical parameters and the like, the traditional equipment is limited by the principles of hole grouping and sowing mechanisms, the defects are obvious, the random seed taking is carried out on the rice grain population due to the forced action of external force, the qualified rate of the rice grain quantity in the hole grouping is low, the damage rate of the rice grain seeds is high, the hole forming performance is poor due to the fact that the rice grains are thrown out along the tangent line of a sowing disc (sowing unit) during sowing, and the improvement of the sowing quality and the yield is limited.

In order to solve the above problems, the applicant has also developed a rice precision hill planter as disclosed in CN108076742A, which can perform precision and continuous planting by being carried on a walking mechanism (which can also be designed as an integral type) and moving along with the walking mechanism. The precise quantity of the rice grains sowed in each hole is ensured by the grain feeding and setting unit and the counting and screening unit which are combined mechanically and electrically; the grain feeding and setting unit integrating natural vibration sliding of rice grains and grain discharging of the flexible grain conveying brush is integrated, so that the damage rate of rice grain seeds is reduced; the seeding rotary transmission disc (seeding unit) with the grain storage chamber and the open-close valve can ensure better seeding and hole forming performance. The particle feeding setting unit and the counting and screening unit are called as a population separation unit according to unified specifications in the industry.

However, in the current hole sowing mode, the population separating unit and the sowing unit are used in a one-to-one assembly mode and are sleeved (counting out the seeds once and sowing once correspondingly), and then a plurality of sleeves are arranged in parallel in rows, so that the quantity of row hole sowing can be increased when the seeding machine walks in one direction, the sowing efficiency is improved, and a problem of influencing the sowing efficiency is exposed in the actual use process. The grain quantity requirement of grain counting is very accurate, the grain discharging process is slow, and the actual grain discharging time of each population separating unit arranged in rows is different; when the following mechanism is used for sowing at the designed interval, the sowing should be carried out immediately and the walking is not stopped, but the counting and grain discharging process of part or individual population separating units is not completed, so that the whole machine needs to wait for all the population separating units in a row to finish counting and grain discharging, and can advance again after the sowing is finished by the corresponding sowing units (otherwise, part of positions can be missed for sowing, and the electric control part of the whole machine prevents the missed sowing condition from the design), so that the whole machine stops when walking, the time is different, and the designed sowing efficiency is reduced.

In CN108076742A, in order to reduce the influence of the speed of counting out the grains on the sowing efficiency, a rotary valve is also used in a counting screening unit, and a double-sowing rotary transmission disc mode is used in an adaptive mode, but the problem still cannot be solved in principle.
