Problems solved by technology

[0004] The structure of the spoon chain and spoon belt type seed pickers is simple, but the vibration is obvious at medium and high speeds, which is easy to cause seed drop, and it is easy to be affected by the vibration of the whole machine after the filling is completed, which will eventually lead to seed leakage
[0005] Garlic particles are large, irregular in shape and size, and rough on the surface, which can easily cause garlic particles to accumulate, arch and block, resulting in leakage or recharging.

Embodiment 1

[0068] The seed disturbing teeth assisted pneumatic garlic seed metering device of the present invention firstly connects the air duct 31 with the negative pressure generator; In the process of passing through the seed filling area 1-1, stir the garlic population in the seed filling area 1-1, and the garlic seeds will be filled in the grooves between the adjacent disturbing seed teeth 20, and will be placed on the negative side of the annular air chamber 30. Under the action of pressure, it is adsorbed on the air hole 21 to complete the seed filling; during this process, it is stirred up by the disturbing teeth 20, and when the garlic seeds that are not adsorbed on the air hole 21 pass through the seed clearing area 1-2, they will be separated by gravity and seed clearing. Under the synergy of the brush 12, it falls into the seed filling area 1-1; then, under the negative pressure of the annular air chamber 30, the garlic seeds adsorbed on the air holes 21 pass through the seed...

Embodiment 2

[0071] On the basis of Embodiment 1, a seed guard plate 11 is provided in the rear housing 1, and the seed guard plate 11 is a curved plate structure, so that the seed filling area 1-1 has enough space to store garlic seeds, ensuring The reliability of seeding is improved.

[0072] The rear housing 1 is provided with a seed clearing brush 12, and the seed clearing brush 12 is vertically upward, and the seed clearing brush 12 is provided with a notch 12-1, so that only the seed-disturbing teeth 20 and adjacent seed-disturbing teeth The garlic seeds adsorbed between the teeth 20 pass through the notch 12-1, and the garlic seeds piled up and arched together are brushed by the seed cleaning brush 12 and fall into the seed filling area 1-1, so as to avoid repeated seed filling.

[0073] The seed protection plate 11 is provided with a rectangular groove 11-1, and a seed protection brush 11-2 is arranged on the rectangular groove 11-1. The disturbing seed teeth 20 that are rotated i...

Abstract

The invention discloses a pneumatic garlic seed sowing device assisted by seed disturbing teeth and a seed sowing method. The pneumatic type garlic seed sowing device comprises a rear shell, a seed sowing disc, a front shell and a rotating shaft, wherein the front shell is connected with the rear shell, the seed sowing disc is arranged in the front shell and the rear shell, the rotating shaft is rotatably connected with the rear shell, the seed sowing disc is coaxially and rotatably connected with the end part of the rotating shaft, the seed sowing disc is connected with the front shell in a movable sealing manner, a seed guide pipe is arranged on the side wall of the rear shell, a seed protecting plate and a seed cleaning brush are arranged in the rear shell, the seed cleaning brush is vertically upward, a rectangular groove is formed in the seed protecting plate, a seed protecting brush is arranged on the rectangular groove, and a seed falling opening is formed in the lower end of the rear shell. By means of a side suction type seed taking mode, the seed taking reliability is ensured; and compared with a spoon chain type seed taking device and a spoon belt type seed taking device, the conditions of seed falling, seed leakage and repeated seed filling are not prone to occurring, and the sowing leakage rate is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of seed metering devices. Specifically, the invention relates to a seed disturbing tooth-assisted pneumatic garlic seed metering device and a seed metering method. Background technique [0002] In recent years, different types of garlic seeders have appeared in the domestic market to realize the mechanized sowing of garlic. Now the garlic seeders mainly include spoon chain type, spoon belt type, clamping type and vibration type, so as to achieve Single-grain seeding, garlic single-grain seeding is one of the key technologies to realize garlic mechanized sowing. [0003] Garlic is a medium-large seed with a large coefficient of variation in shape and size, and a rough surface. Leakage and refilling of the garlic seed picker are unavoidable. [0004] The spoon-chain and spoon-belt seed pickers have a simple structure, but they vibrate significantly at medium and high speeds, which can easily cause seed drop...
