Description

Fan transmission device on air-aspiration type precision seeder

Technical Field

The invention relates to the technical field of transmission devices, in particular to a fan transmission device on an air-aspiration type precision seeder.

Background

A planting machine for a planter uses crop seeds as planting objects. Seeders for certain types or crops are often referred to by the name of the crop type, such as grain drill, corn hill planter, cotton planter, grass spreader, and the like. The object planted by the seeding machine is the seed of the crop or the coating seed made into the shape of pill. It can be divided into vacuum seed sowing machine broadcast sowing machine, drill sowing machine and hill sowing machine according to sowing mode. An air-suction seeder is a seeder which sucks seeds by negative pressure to realize precision seeding. Compared with a mechanical seeder, the mechanical seeder has stronger advantages in technical performance. The precision sowing can realize single-seed sowing, the seed consumption can be reduced by the precision sowing, the seed cost is reduced, the sowing precision is improved, the qualified rate of the sowing row spacing is obviously higher than that of mechanical precision sowing through field actual detection, the miss sowing rate and the re-sowing rate are obviously reduced, the sowing adaptability is strong, the sowing requirements can be met for various types of crop seeds such as long round, flat, large, medium and small seeds, the seeds are hardly damaged, and the high-speed sowing can be realized.

Sowing machines in which the seeds are spread evenly over the sowing field are called spreaders. A common model is a centrifugal spreader attached to the rear of an agricultural transport vehicle. Consists of a seed box and a broadcast sowing wheel. The seeds fall onto the sowing wheel from the seed box and are sown along the tangential direction under the action of centrifugal force. Powdered or granular fertilizers, lime and other materials may also be broadcast. A mechanical hill planter which performs seeding with accurate seeding amount, planting row spacing and depth. Has the advantages of saving seeds, avoiding thinning operation after seedling emergence, ensuring that the nutrition area of each crop is uniform, and the like. The method is mainly single-grain hole sowing and multi-grain hole sowing which can accurately control the grain number of each hole. Is generally formed by improving various seeding apparatuses of a hill-drop planter.

Traditional air-aspiration type precision planter often adopts two sets of power device when using, one set promotes the seeder and removes at the during operation, one set of power supply as the fan, just need rotate in view of the fan generally only at the seeding during operation, this kind of way is great to the wasting of resources, some advanced enterprises simply merge two sets of power device, but fan and gyro wheel all need to overhaul after long-time work, the inconvenient maintenance of above-mentioned way is unfavorable for the maintenance of follow-up during operation to the device, consequently, the fan transmission who conveniently overhauls is urgently needed.
