Problems solved by technology

First, ZL200910075574.4 uses a complex structure to hang the sieve, which is troublesome and expensive to manufacture. If the sieve is hung directly according to the attached drawing in the manual, the sieve may tilt
Second, the motors used in the above two patents are placed in the middle of the bottom of the sieve. If the seal is not tight, the powder will enter the motor, and there is powder around the motor. The heat dissipation of the motor is not good, and the temperature is high, which may affect the life of the motor.
The axes of the motors in the two patents are vertical. Through comparison, it is found that the vibration is not the strongest in this setting.
Thirdly, for the situation where there are many and heavy powders, and the degree of drying is not enough, if the above two patents are used, the powder may not be sprinkled down or spread too slowly, but the two patents do not involve the problem of mesh size adjustment. The size of the area that allows the powder to pass is fixed and cannot be adjusted, which is not conducive to solving the problem that the powder cannot be sprinkled or spread too slowly
There are other aspects to be improved in the above two patents

Embodiment 1

[0030] Such as figure 1 As shown, an automatic powder spreader includes a vibrating screen 1, a motor 11, an eccentric block 12 installed on the motor shaft, a motor cover 13, a flexible part 2, a connecting part 4 and a supporting part. Described support part is divided into vertical support part 3 and transverse support part 10, and transverse support part is contained on the longitudinal support part, and battery 8 is housed in its longitudinal support part; It is connected with the longitudinal support and the transverse support, and makes the vibrating screen horizontal; the motor 11 and the eccentric block 12 are fixed on the outside of the vibrating screen ring, and are covered by the motor cover 13; the axis of the motor is in a horizontal position Or the included angle with the horizontal plane is less than 45 degrees; the auxiliary sieve 14 for sharing the weight of the medicine powder, reducing the load of the vibrating sieve, and improving the powder spreading abil...

Embodiment 2

[0044] If the longitudinal support is a combination of a pipe and a flashlight, the pipe can be composed of a fixed pipe and a telescopic pipe, and the telescopic pipe is inserted into the fixed pipe. This can expand the range of spraying. The socket socket 5 that links to each other with battery, the potentiometer 7, the switch 8 that controls motor motion are housed on flashlight 16, and tube and flashlight combination are connected by mechanical means, can disassemble. The screen position is lower than the flashlight, not blocking the light of the lamp. The automatic powder sprinkler of this embodiment has two purposes, that is, it can be used for both lighting and powdering. When not raising silkworms in winter, the plug can be pulled out from the jack, the sieve, the motor, and the motor cover are removed as a whole, the tube is removed from the flashlight, and the flashlight is left for lighting. All the other are with embodiment 1.

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...
