Abstract

The utility model relates to a cone cylinder revolving wheat primary cleaning machine which belongs to a cleaning device for cereal crops, particularly primary cleaning equipment for wheat. The utility model is characterized in that one end of a sieve is fixed to a small end ring, and the other end is fixed to a big end ring for forming a cone cylinder sieve. The big end ring and the small end ring are connected with each other by a double-thread pillar. The big end ring and the small end ring are both supported on a supporting roller group, the small end ring and a pulley are integrated, and a dirty wheat inlet is arranged at the small end ring. An impurity outlet is arranged at the big end ring, a clean wheat outlet is arranged at the lower part of the cone cylinder sieve, and the upper part of the cone cylinder sieve is provided with a dust suction mouth. The utility model has the characteristics of simple structure, good sealability, high production capacity, and favorable preliminary cleaning effect.

Description

The rotary wheat of awl tube is clear just

The utility model relates to the preliminary cleaning equipment of the cleaning plant of cereal, particularly dirty wheat.

In the existing at home small flour processing set equipment, the previous cleaning of wheat is a weak link, the product that does not have typing, special is being that the slubbing cleaning technology is in the equipment of wheat scourers, without impurity such as the bundle bag fag end that is mixed in the dirty wheat of previous cleaning, the wheat head, masonries, wheat scourers sieve sheet is damaged easily, shortened service life, and fag end easily twines to re-pack and waits parts, down to burning out motor.And cleaning and technological effect that this can reduce wheat influence flour quality.

The purpose of this utility model provides grow wheat clear just, and it is simple in structure, running is steady, good airproof performance, practicality is energy-conservation, output is higher, can improve flour quality and flour extraction.

The realization the technical solution of the utility model is: on the first clear basis of forming by suction port, dirty wheat import, screen cloth, frame, clean wheat outlet and impurity outlet of wheat, do following improvement,

(1) end of screen cloth is fixed on the small end circle, and the other end is fixed on the big end circle, constitutes an awl shaft screen net, and big end circle is connected by studs with the small end circle;

(2) big end circle and small end circle all are supported on the support roller group, and small end circle and belt pulley are one, and the dirty wheat import is positioned at small end circle place, and the impurity outlet is at big end circle place, and the below of awl shaft screen net is clean wheat outlet, and the top is a suction port.

Below, a specific embodiment according to shown in the Figure of description is further described the technical solution of the utility model.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model impurity port of export schematic diagram;

Fig. 3 is the support schematic diagram between end circle and support roller.

Referring to each figure, screen cloth 4 of clear is awl shaft screen net at the beginning of this, and promptly an end of screen cloth 4 is fixed on the small end circle 2, and the other end is fixed on the big end circle 7, big end circle 7 is connected by six roots of sensation studs 3 with small end circle 2, constitutes a cone barrel firm and easy accessibility and sieves.Big end circle 7 and small end circle 2 all are supported on the support roller group 11, small end circle 2 is an one with belt pulley, whole conical screen assembly by driven by motor in 11 rotations of support roller group, support roller group 11 is also rotated respectively thereupon, dirty wheat import 1 is connected on accent place in the small end circle 2, impurity outlet 8 is contained in big end and encloses on the frame 6 at 7 places, adorns clean wheat outlet 12 on the following methods, rack of awl shaft screen net 4, and suction port 5 is then adorned in the top of screen cloth 4.For wheat is separated preferably with impurity, the α angle of taper screen cloth 4 is preferably elected 6 °～9 ° as, and screen cloth should be used per inch 4 purpose piano-wire screens, or with the steel plate sieve aperture of φ 6mm.Sealing backplate 9 is housed around the frame 6, whole conical screen assembly is included in wherein, can avoid dust to fly upward effectively.On frame 6 end caps, glass window 13 is housed, to observe dirty wheat and separate impurities situation near big end circle 7 places.

During use, the small end circle of driven by motor conical screen assembly, dirty wheat enters the awl shaft screen by the small end circle from the dirty wheat import, and wheat stirs thereupon, passes screen cloth and flows to clean wheat outlet, outside the discharge machine; And big impurity such as fag end, the wheat head, clod, masonry are discharged outside the machine because rotation of awl shaft screen and gravity effect flow to the impurity outlet of big end circle place again; The awl shaft screen is caused dust in the rotation separation process, is closed in the sealing backplate of installing around the frame, outside suction port discharge machine, has avoided dust to fill the air again.

From above-mentioned the technical solution of the utility model, it is simple in structure, handling ease, manufacturing cost is lower, output is higher; Adopt the rotary conic sieve to help the wheat flow by gravity and transport, it both can save power and energy-conservation, can prolong wheat and separate impurities process again, improved cleaning efficiency, for next procedure creates favorable conditions; Dress sealing backplate can reach good sealing around the frame, has improved working environment.But this machine both unit also can be used as the wheat cleaning corollary equipment in the small flour processing set equipment, to help improving flour quality and flour extraction as the first clear equipment of wheat before having put in storage.

Claims

1, the first clear of the rotary wheat of a kind of awl tube mainly is made up of suction port, dirty wheat import, screen cloth, frame, clean wheat outlet and impurity outlet, it is characterized in that

2, by the first clear of the claim 1 rotary wheat of described awl tube, the α angle that it is characterized in that the taper screen cloth is 6 °～9 °, and the sealing backplate is housed around the frame.

3, by the first clear of the rotary wheat of the described awl of claim 2 tube, it is characterized in that boring the shaft screen net and select per inch 4 purpose piano-wire screens for use, or, glass window is being housed near holding circle place stander end to cover greatly with the steel plate sieve aperture of Φ 6mm.
