The seeding machine comprises a machine frame, a seeding device and a fertilizing device; the fertilizing device comprises a fertilizer box, fertilizer discharging devices and fertilizer guiding pipes, the seeding device comprises seed holding boxes, seed taking devices and seed guiding pipes, each seed taking device comprises a seed taking chamber and seed taking spoons, the top of each seed taking chamber is connected with one seed holding box, and one side surface of each seed taking chamber is provided with a seed taking opening; the part, located at the outer side of each seed taking opening, of the machine frame is provided with positioning sleeves, a seed outlet is arranged between two positioning sleeves and one corresponding seed taking opening, and one seed outlet is connected with one corresponding seed guiding pipe; and each positioning sleeve is provided with one spiral hollow insertion groove, each seed taking spoon includes a spoon handle and a spoon groove, each spoon handle is provided with a punching hole, each spoon handle is arranged in one positioning sleeve in a sleeving manner and movably connected with the positioning sleeve through one connecting rod, one end of each connecting rod passes through one corresponding hollow insertion groove, and each connecting rod is driven to move back and forth along one corresponding hollow insertion groove by one reciprocating driving device. The seeding machine provided by the invention has diversified functions and a wide application range; and the seeding machine adopts turnover-type sampling spoons for seeding, so that no clogging occurs, and a seeding amount can be better controlled.

Description

technical field [0001] The invention belongs to the technical field of agricultural seeding devices, and specifically provides a multifunctional combined seeder. Background technique [0002] With the development of agricultural mechanization, many crops are sown by machinery. An excellent mechanical sowing must meet the following basic requirements at the same time: (1) According to the differences in the shape, size and surface characteristics of various crop seeds, design a corresponding seed picking device to separate the seeds; (2) Seeding device The number of seeds taken out each time and the number of seeds taken per unit time are relatively constant. At the same time, the amount of seeds taken should match the speed of the machine to ensure a suitable density (plant distance); (3) The seed taker must ensure continuous (4) Due to the harsh working environment of the seeder, it needs to face scenes such as blockage, collision, and adhesion caused by sand, soil, mud, d...

Problems solved by technology

This seed meter has the disadvantage that it is difficult to control the seeding rate. For example, when a large seeding density is required, the disc needs to run at a high speed. The problem brought about like this is that the seeds in the spoon may be thrown out under the action of centrifugal force; On the one hand, for rice, which has a rough surface, irregular shape, and large aspect ratio, the angle of entry into the spoon is random, and it is difficult to determine the shape and size of the seed picking spoon. If the seeds enter the spoon in the same direction , the smaller spoon slot can take 3-4 seeds at a time, when the seeds enter the slot at 3 or more angles, there may be only one seed left in the spoon; on the contrary, if a larger spoon is used, Sometimes 2-3 seeds may be taken, and sometimes 7-8 seeds may be taken, resulting in very uneven sowing, which cannot meet the needs of precision sowing
