Abstract

The utility model is a modified structure for airflow feeders, comprising a suction feeder and an adjustable shift sleeve, and a suction tube and an air supply mechanism are collaterally arranged. By the blowing of airflow, raw materials will pass through the suction feeder and the suction tube and automatically feed into another material-transition cylinder, thus achieving the function of automatic feeding. The use of the modified the suction feeder and the shift sleeve enhances smooth feeding and avoids obstruction, thus simply and easily adjusting the intensity of air supply to control the feeding rate and obtaining practical progress.

Description

Air-flow feed appliance structure-improved

Technical field

The utility model relates to a kind of air-flow feed appliance structure.

Background technology

Air-flow feed appliance commonly used, as shown in Figure 1 and Figure 2, include a tubulose suction tube 1, externally fit is with combined block 2, and form an annular space 21, establish in addition with oblique hole 11 at the tube wall of suction tube 1, and the combination of the side of combined block 2 is with a tracheae 31, be connected with at supply ventilating fan 3 places, and on suction tube 1 directly socket with feed pipe 4.During use, when supply ventilating fan 3 air-supply, air admission annular space 21 also is blown into suction tube 1 and is upwards flowed by oblique hole 11, at this moment, can will be positioned at the raw material 51 of storage vat 5, by the suction of air-flow, deliver to treating in the charging basket 6 of top, obtain the purpose of air-flow feeding.Though this conventional design can reach the effect of certain degree, yet its rate of feed also can't change in simple and easy adjustment, and its oblique hole 11 is drilling construction one by one, in the enforcement comparatively complexity take a lot of work, difficult its degree of precision of grasping, 1 time perforate of the material suction device of its oblique straight line in addition is easy to generate the bad phenomenon of obstruction in use, so still remain to be improved.

Summary of the invention

So main purpose of the present utility model is to provide a kind of air-flow feed appliance structure-improved, include the material suction device of improvement, cooperate with adjustable combined cover, can simple and easy adjustment rate of feed, be not easy to produce the phenomenon of obstruction.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of air-flow feed appliance structure-improved, include a material suction device, combination is with a combined cover, be connected with respectively with a feed pipe and a tracheae, utilize a supply ventilating fan to dry, air is sent in the combined cover, and sent to feed pipe to tracheae, produce suction, and raw material upwards can be sent, material suction device is provided with streamline contour under shed and arc subulate upper end, and its central outside is provided with the threaded portion, combined cover inside is provided with a negative thread, be screwed with the threaded portion of material suction device, establish an inside groove in the combined cover in addition, the arc subulate upper end of material suction device is inserted therebetween, and form a clearance-adjustable, as the transmission passage of air-flow.

Adopt the advantage of the present utility model of technique scheme to have: can simple and easy adjustment rate of feed, be not easy to produce the phenomenon of obstruction, and implement simpler.

The specific embodiment

Now cooperate graphicly, illustrate that feature of the present utility model and effect are as follows:

Please consult Fig. 3 earlier to shown in Figure 5, the utility model mainly provides the material suction device 7 of improvement, and cooperation is formed with combined cover 8.Wherein the lower end of material suction device 7 is made as and has streamline contour opening 71, and its top then is made as arc subulate upper end 72, and outside system of central authorities is provided with threaded portion 73; The inside of combined cover 8 is provided with negative thread 81, can be screwed with the threaded portion 73 of material suction device 7, be one and make up the two, be formed with an inside groove 82 in the combined cover 8, arc subulate upper end 72 with ccontaining material suction device 7, be provided with a perforate 83 in the side, be communicated with at supply ventilating fan 3 places for linking with tracheae 31, its top then can utilize the lower end of a collar 9 with socket feed pipe 4.

When using, air is blown into by tracheae 31, and carries over the arc subulate upper end 72 of material suction device 7 and inside groove 82 gaps of combined cover 8, upwards send, produce a updraft, provide suction that the raw material 51 that the below is positioned at storage vat 5 is upwards sent, and reach the effect of air-flow feeding.The utility model is because material suction device 7 has streamline contour opening 71, can make feeding more smooth and easy and bad situation that do not have an obstruction takes place.

Please cooperate Fig. 6, shown in Figure 7, another principal character of the present utility model is: speed that can simple and easy adjustment feeding, it is by turn combined cover 8 and material suction device 7, to change the gap of inside groove 82 and arc subulate upper end 72, it is the size of may command air-flow, adjust the speed of feeding indirectly, and have practical effect.

In sum, the utility model shows the important document met patent, should check and approve to being to be mere formality application in accordance with the law.
