Abstract
The utility model relates to a powder material shaftless spiral feeding pipe which is arranged on a feeding position of the front end of a coated cylinder. The powder material shaftless spiral feeding pipe comprises a driving motor, a driving chain wheel, a driven chain wheel, an input shaft, a feeding pipe, a material inlet and a material outlet, wherein the driving motor drives the driving chain wheel which drives the driven chain wheel through a chain, the driven chain wheel drives an output shaft of the driven chain wheel to rotate, and the output shaft is arranged inside the feeding pipe in a coaxial mode. The front end of the feeding pipe is provided with the material inlet, and the rear end of the feeding pipe is provided with the material outlet. The powder material shaftless spiral feeding pipe is characterized in that the output shaft of the feeding pipe is provided with one end of a spring, and the other end of the spring is a suspension arm. According to the powder material shaftless spiral feeding pipe, the spring is utilized to replace a screw, as the screw is a shaftless screw, the blocking phenomenon caused by powder material conveying is avoided, and normal conveying of the powder material is guaranteed. One end of the arranged spring is fixedly arranged, the other end of the arranged spring is freely suspended, and therefore the feeding pipe can be knocked when the spring rotates, adhering connection of the powder material on the inner wall of the feeding pipe is avoided, and work efficiency is improved.
Description
Technical field
The utility model belongs to the powder transportation art, relates to the powder feed pipe, the shaftless spiral feed pipe of especially a kind of powder.
Background technology
Along with the development of science and technology, for slowly-releasing, chemical fertilizer adopts the coating mode usually, is applied to thus the coating cylinder.Be filled with chemical fertilizer powder and film clothing shower nozzle in the coating cylinder, roll and make the powder coating by film clothing shower nozzle ejection liquid, coating cylinder.At present, usually adopt the motor-driven approach screw to carry when carrying powder in the coating cylinder, shortcoming is: 1, powder enters and is bonded in easily in the feed pipe on the feed pipe inwall, can't remove, can only be with artificial rolling flowing mode cleaning, and labour intensity is large, inefficiency; 2, plug was dead easily after powder entered feed pipe, thereby caused motor overheating, and what impact was carried normally carries out.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of powder transport efficiency high, the effective shaftless spiral feed pipe of powder.
The utility model solves its technical matters and is achieved through the following technical solutions:
The shaftless spiral feed pipe of a kind of powder, be installed in front endfeed place of coating cylinder, comprise drive motor, drive sprocket, driven sprocket, input shaft, feed pipe, inlet point and discharging opening, drive motor drives drive sprocket, drive sprocket is by the chain drive driven sprocket, driven sprocket drives its output shaft rotation, this output shaft is coaxial to be installed in the feed pipe, front end at feed pipe arranges inlet point, rear end at feed pipe is provided with discharging opening, it is characterized in that: the output shaft in feed pipe is installed an end of a spring, and the other end of spring is cantilever.
And described output shaft is that coaxial engagement is installed with spring.
Advantage of the present utility model and beneficial effect are:
1, this feed pipe adopts spring to substitute screw rod, because screw rod is shaftless screw rod, has therefore avoided powder to carry the latch up phenomenon that produces, and has guaranteed the normal conveying of powder.
2, the spring installed of this feed pipe is that an end is fixedly mounted with, and the other end is freely unsettled, can knock feed pipe when spring rotates thus, has avoided the adhesion of powder on the feed pipe inwall, improves operating efficiency.
3, being fixedly mounted with as luer engages with is fixedly mounted with of the spring of this feed pipe and input shaft, the larger installation of power is more firm, has avoided the disengaging of spring and input shaft.
4, this feed pipe design science is reasonable, has solved many defectives that existing feed pipe exists, and is the regeneration product of existing feed pipe, is with a wide range of applications.

Fig. 2 is structure cutaway view of the present utility model.
The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
The shaftless spiral feed pipe of a kind of powder, be installed in 2 front endfeeds place of coating cylinder, comprise drive motor 5, drive sprocket 3, driven sprocket 4, input shaft 6, feed pipe 1, inlet point 7 and discharging opening 9, drive motor drives drive sprocket, drive sprocket is by the chain drive driven sprocket, driven sprocket drives its output shaft rotation, and this output shaft is coaxial to be installed in the feed pipe; Front end at feed pipe arranges inlet point, is provided with discharging opening in the rear end of feed pipe.
Innovative point of the present utility model is:
An end of a spring 8 is installed in coaxial engagement on the output shaft in feed pipe, and the other end of this spring is cantilever.
Claims (2)
1. shaftless spiral feed pipe of powder, be installed in front endfeed place of coating cylinder, comprise drive motor, drive sprocket, driven sprocket, input shaft, feed pipe, inlet point and discharging opening, drive motor drives drive sprocket, drive sprocket is by the chain drive driven sprocket, driven sprocket drives its output shaft rotation, this output shaft is coaxial to be installed in the feed pipe, front end at feed pipe arranges inlet point, rear end at feed pipe is provided with discharging opening, it is characterized in that: the output shaft in feed pipe is installed an end of a spring, and the other end of spring is cantilever.
