Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0025] Such as Figure 1 to Figure 3 As shown, a kind of air suction seed metering device according to the preferred embodiment of the present invention includes a front housing 1, a rear housing 2 and a seed suction tray 3, and the seed suction tray 3 is located between the front housing 1 and the rear housing 2 . The front housing 1 and the rear housing 2 are fastened together by bolts, of course, other fastening methods, such as buckle, adhesion, etc., may also be used.

[0026] Specifically, the front housing 1 includes a seed introduction area 11, a seed storage area 12 and a seed discharge area 13. The seed introduction area 11 is connected to the top of the seed storage area 12 through the guide tube 4, and the bottom of the seed storage area 12 is connected to t...

Abstract

The invention discloses an air-suction seed metering device, which comprises a front casing, a rear casing and a seed suction tray, the front casing includes a seed feeding area, a seed storage area and a seed discharge area, and the rear casing includes The front end forms a positive pressure zone and a negative pressure zone. Through the interaction between the positive pressure zone and the negative pressure zone, the seeds are adsorbed on the negative pressure zone on the rear shell, and the seeds will fall when they rotate to the positive pressure zone, so as to realize rapid seed suction and discharge, and the seed damage rate is low. Low, stable seed suction.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an air suction seed metering device. Background technique [0002] Sowing is a basic link in agriculture, and the quality of sowing will affect the rate of emergence in the future. With the development of modern technology, the technical level of seeders has also been further improved. Especially the current precision seeder has the advantages of saving good seeds, no need for thinning, and even distribution of plants in the precision sowing field to achieve reasonable dense planting and benefit the growth of seedlings. At the same time, precision broadcasting also has the effects of saving time, labor and increasing production. Therefore, precision seeding has become a major trend nowadays. [0003] The main factor affecting the seeding quality of precision seeders depends on the performance of the metering device. It can be said that the seed meter is the hea...
