Abstract

The invention relates to an automatic powder spreader, which comprises a vibration screen, a motor, an eccentric block mounted on a motor shaft, and a motor housing, wherein the vibration screen is respectively connected with a longitudinal support part and a transverse support part through a flexible part and a connecting part; the motor is fixed outside a screen ring of the vibration screen, and the axis of the motor is located at a horizontal position; and an auxiliary screen for sharing the weight of chemical powder, lightening the load of the vibration screen and improving the powder spreading capability is also arranged in the vibration screen. The auxiliary screen is independently suspended on the support parts, the screen bottom of the auxiliary screen consists of a plurality of angle-adjustable vanes, and the angles of the vanes are adjusted to control the gaps of the vanes. The automatic powder spreader has the advantages that the structure is simple, the cost is low, the screen is stable and cannot incline, the vibration strength is high, the service life of the motor is long and the adaptability is wide, and the automatic powder spreader is mainly used for silkworm breeding and can also be used for powder spreading in medical treatment and public health units.

Description

technical field

[0001] The invention belongs to the field of dusting mechanical tools, and in particular relates to an automatic duster for silkworm farmers to dust powder. Background technique

[0002] Farmers who raise silkworms need to sprinkle lime powder and other medicinal powders frequently to prevent and treat various silkworm diseases. Silkworm farmers generally use the round sieve used to filter flour at home to charge the silkworms with medicine, and shake the sieve ring constantly to apply the medicine to silkworms; some people use gauze bags to wrap the medicine powder and beat it continuously to force the medicine powder to fall. When the above-mentioned method is used to spread the medicinal powder, the dusting is uneven, the work efficiency is low, and the medicinal powder is flying, which affects human health.

[0003] In 1994, Yu Daguo obtained the patent of "Automatic Powder Spreader for Sericulture", the patent number is ZL93236571.X. The powder spreade...
