Abstract
An air compensation device for a paddy pounder includes an air-cored main shaft 1, a material inlet opening 2 and a husk suction hopper 4. The air-cored main shaft 1 is provided with a hole 6 at the part of a milling chamber 5; an inner cavity of the air-cored 1 is communicated with the milling chamber 5 through the hole 6; the husk suction hopper 4 is connected with the milling chamber 5. The invention is characterized in that the middle back section of the milling chamber 5 is provided with an air inlet hole; the milling chamber 5 is communicated with the outside atmosphere through an air inlet hole3. As the air flow coming from the air inlet hole passes through a material blocking area with high density and high inner pressure to play the role of channelizing and gas lubrication on the materials and lead the materials to be in a fluidized state in the milling chamber, the air compensation device reaches the goal of preventing materials from piling and blocking in the milling chamber, solving the situation of uneven pressing in the milling chamber, effectively channelizing a high pressure area in the milling chamber, reducing the temperature rising of a finished product of the paddy pounder, decreasing the grain cracking rate, reducing the impurity content in the finished product, alleviating the load of a motor, reducing abrasion on parts and improving the working efficiency.
Description
Affiliated technical field
The technology of the present invention relates to the air compensation device of rice mill.
Background technology
In the prior art, the air compensation device of rice mill comprises hollow main shaft 1, charging aperture 2, inhales chaff bucket 4.The part that hollow main shaft 1 is positioned at husk rice chamber 5 has hole 6, and the inner chamber of hollow main shaft 1 is connected with husk rice chamber 5 by these holes.The air inlet of inhaling chaff bucket 4 is communicated with the air outlet of husk rice chamber 5.The power of mending wind is from mending the wind blower fan.The air inlet of mending the wind blower fan links to each other with the air outlet of inhaling chaff bucket 4.The benefit wind path line of the air compensation device of above-mentioned rice mill has two.Article one, be: charging aperture 2 that---husk rice chamber 5---inhales chaff bucket 4.Second is: the two ends of hollow main shaft 1---husk rice chamber 5---inhales chaff bucket 4.Rice mill benefit wind process is as follows in the prior art: material enters husk rice chamber 5 from charging aperture 2 through propellers.Because the graviational interaction of external air-introduced machine 7 also has a large amount of air to enter husk rice chamber 5 in the time of from charging aperture 2 chargings, these air are discharged by the sieve sheet.Because the conveying effect of these air, make the mobile more smooth and easy of material at husk rice chamber 5 leading portions, these air hexyls originally drain in 5 posterior segments, husk rice chamber.Therefore, in the posterior segment of husk rice chamber 5 owing to lack the conveying effect of air, substantially be to promote material by mechanical external force to be fed forward, form the material obstruction zone of a high density, high interior pressure, this material stops up the rice finished product temperature rise increase that regional formation makes that rice mill exports, and broken rice rate increases, impurity content in the finished product increases, motor load strengthens, the wearing and tearing aggravation of part, and operating efficiency reduces.When especially processing the new grain of high moisture content, clogging is more serious, even causes deadlock.
Summary of the invention
The invention provides a kind of air compensation device of rice mill, the air compensation device of this rice mill has solved posterior segment, husk rice chamber material blocking problem effectively.
In order to reach the solution above-mentioned purpose, technical scheme of the present invention is following design:
A kind of air compensation device of rice mill, comprise hollow main shaft, charging aperture, suction chaff bucket, the part that the hollow main shaft is positioned at the husk rice chamber has hole, the inner chamber of hollow main shaft is connected with the husk rice chamber by these holes, the air inlet of inhaling the chaff bucket is communicated with the husk rice chamber, it is characterized in that: the posterior segment in the husk rice chamber has fresh air inlet, and the husk rice chamber is connected with ambient atmosphere by fresh air inlet.
The route of rice mill benefit wind has two in the prior art.Article one, be: charging aperture that---husk rice chamber---inhales the chaff bucket.Second is: the two ends of hollow main shaft---husk rice chamber---inhales the chaff bucket.Article three, fresh air inlet---husk rice chamber---is inhaled the chaff bucket.A kind of benefit wind rice mill of the present invention, because the place is provided with fresh air inlet in the husk rice chamber, the atmosphere air communication of coming in from fresh air inlet is crossed and is passed high density, the material of pressing in high stops up the zone, material is produced the effect of dredging with gas lubrication, make material be fluidized state in the husk rice chamber, reached the purpose that prevents that material from stopping up in the accumulation of husk rice chamber, solved the uneven situation of husk rice intraventricular pressure, effectively dredge the indoor higher-pressure region of husk rice, reduced the temperature rise of rice mill finished product, reduced broken rice rate, reduced the impurity content in the finished product, alleviate motor load, reduced the wearing and tearing of part, improved operating efficiency.

The specific embodiment
A kind of air compensation device of rice mill, shown in Fig. 2,3, comprise hollow main shaft 1, charging aperture 2, inhale chaff bucket 4, the part that hollow main shaft 1 is positioned at husk rice chamber 5 has hole 6, the inner chamber of hollow main shaft 1 is connected with husk rice chamber 5 by these holes 6, and the air inlet of inhaling the chaff bucket is communicated with husk rice chamber 5.Have fresh air inlet 3 in the posterior segment of husk rice chamber 5, husk rice chamber 5 is connected with ambient atmosphere by fresh air inlet 3.
Rice mill is when work, and material enters husk rice from feed hopper through propeller and stops up, and inhales the chaff chamber and connects air-introduced machine.Air-flow enters husk rice chamber 5 " highly dense district " from two ends, the fresh air inlet 3 of hollow spindle 1, produce to carry equably successively, dredge and the active force of gas lubrication, make material waltz through discharging opening and discharge, air-flow and chaff powder then pass the sieve plate hole by outside the air-introduced machine aspiration machine.Described rice mill air compensation device has solved to innovation the uneven problem of husk rice chamber 5 pressure that exists in the prior art.Rice mill air compensation device of the present invention and since husk rice chamber 5 be provided with fresh air inlet 3, in husk rice chamber 5, formed three gas channels through the husk rice chamber.The special area that utilizes air-flow to pass high density, press in high produces the effect of carrying, dredging with gas lubrication, makes material be fluidized state in the husk rice chamber.Having avoided material to pile up in the husk rice chamber stops up, solved the uneven situation of husk rice intraventricular pressure, effectively dredged the indoor higher-pressure region of husk rice, reduced the temperature rise of rice mill finished product, reduce broken rice rate, reduced the impurity content in the finished product, alleviated motor load, reduce the wearing and tearing of part, improved operating efficiency.
