Combined-operation air-suction type precision seeder for vegetables and medicinal materials

Abstract

The invention discloses a combined operation vegetable and medicinal material air-aspiration type precision seeder which comprises a seeder body and an air-aspiration type seeding box, the seeding box comprises a box cover and an air pipe communicated with the box cover, the air pipe is conventionally connected with a fan rotating at a high speed through an existing well-known technology, the scheme is not described, the interior of the box cover is rotatably connected with a seed disc, and the seed disc is rotatably connected with the seed disc. The seed discs comprise a first seed disc, a second seed disc and a third seed disc, the first seed disc comprises a shaft rod which is electrically connected, the shaft rod is fixed with the output shaft end of the motor and provides rotating power for the first seed disc, and the second seed disc and the third seed disc are arranged on the shaft rod in a sleeving manner and can be fastened and adjusted, so that the aperture size of the seed discs can be conveniently adjusted; a plurality of first suction holes are annularly and uniformly formed in the first seed disc, the second seed disc and the third seed disc, second suction holes as many as the first suction holes are annularly and uniformly formed in the second seed disc, and third suction holes as many as the first suction holes are annularly and uniformly formed in the third seed disc.

Description

technical field [0001] The invention relates to the field of air-suction seeders, in particular to an air-suction precision seeder for combined operations of vegetables and medicinal materials. Background technique [0002] Vegetable medicinal material air suction seeder is a kind of seeder that relies on negative pressure to absorb seeds to achieve precision sowing. The fan rotates at high speed to make the inside of the seeding box negative pressure, and then makes the seeds in the storage chamber on the other side of the seed tray , is adsorbed at the suction hole, and then rotates to the seed guide tube and falls to achieve precise seeding. The existing air-suction seeder has the following disadvantages when used. 1. The traditional storage chamber is placed in the seed On the side of the disk away from the trachea, the seeds are adsorbed in the suction hole under the action of negative pressure, and then rotated at least 180 degrees before falling into the seed tube, wh...

Problems solved by technology

[0002] Vegetable medicinal material air suction seeder is a kind of seeder that relies on negative pressure to absorb seeds to achieve precision sowing. The fan rotates at high speed to make the inside of the seeding box negative pressure, and then makes the seeds in the storage chamber on the other side of the seed tray , is adsorbed at the suction hole, and then rotates to the seed guide tube and falls to achieve precise seeding. The existing air-suction seeder has the following disadvantages when used. 1. The traditional storage chamber is placed in the seed On the side of the disk away from the trachea, the seeds are adsorbed in the suction hole under the action of negative pressure, and then rotated at least 180 degrees before falling into the seed tube, which leads to an increase in the stroke of the adsorbed seeds. The vibration generated when the tractor is driven, as well as the unevenness of the land itself, increase the probability of seed falling. The larger the stroke, the greater the probability of falling, which leads to the inability to achieve high-precision precision seeding At the same time, in order to ensure that the seeds do not fall during the rotation of the large stroke, a negative pressure fan with greater suction is required. The tractor drives the fan to rotate at high speed, which will consume a certain amount of fuel; 2. Different varieties of vegetables and medicinal materials The seed particles of different particles are different. When air suctioning seeds of different particles, the seed disk needs to be replaced. The traditional way is to disassemble and replace, which is more complicated to replace and takes a long time to operate.
