Abstract

A self-separating rice mill provided by the utility model improves the structure of the traditional rice mill. On the basis of the bran cleaning sorting structure of a rice screen of the present rice mill, the self-separating rice mill is provided with a draught fan wheel which can rotate together with a rice milling main shaft, and the draught fan wheel is positioned on the feeding end of the rice milling main shaft. A blast pipe connected to the casing body of the draught fan communicates with a rice bran separating box installed on a discharging port. During the rice milling operation, the rice separated from the bran through the rice screen is sent to the rice bran separating box to clean the bran with air for second time, so the very little bran left and immingled in the rice can be completely and cleanly sorted out, and finished product of clean rice with high quality is made. The self-separating rice mill has the advantages of reasonable design, simple structure, easy manufacture and convenient use and installation, which can obviously improve the appearance quality of the rice and is provide with excellent market outlook.

Description

The self-separation rice mill

Technical field:

The utility model relates to the machine that grinds system paddy, belongs to the technical field of agricultural machinery, specifically a kind of self-separation rice mill, and the peasant family that is particularly suitable for vast paddy rice producing region is installed and used.

Background technology:

We know: rice passes through operations such as the system of stone roller shells, chaff is removed in sorting with paddy and is processed into.For the amount of labour that alleviates peasant's husk rice operation with improve the quality that rice, recently, popularized in China vast paddy rice producing region and to be suitable for the light-duty rice mill that peasant family is installed and used, it have volume little, in light weight, manipulate advantages such as simple and convenient, be subjected to the favor of vast farmers deeply.Up to now, the rice mill that generally uses in vast rural area, it mainly has rice huller screen by device in the body that is installed on frame, the body and is made of husk rice roller, the feed hopper of bearing block support and several parts such as discharge bucket of being controlled by adjustable plate, during the husk rice operation, paddy is sent in the rice mill by feed hopper, by the husk rice roller paddy is ground the system shelling, after chaff is removed in the rice huller screen sorting, can export the rice finished product again by discharge bucket.Though, the present rice mill that uses can grind the system shelling to paddy simultaneously and chaff twice flow chart is removed in sorting, but in practical work process, influence each other between the degree of sorting that the stone roller pressing pressure of paddy husking and rice huller screen remove chaff, when practical operation, be difficult to accurately hold, increase the stone roller pressing pressure and can improve the separating effect that rice huller screen removes chaff, increase the quantity of cracking rice, reduce rice milling yield but grind the too high meeting of pressing pressure; Can influence the separating effect that rice huller screen removes chaff again if the stone roller pressing pressure is crossed to hang down, can deposit the chaff material by folder in the rice finished product, have a strong impact on the product quality of rice finished product, this is the major technique defective that present rice mill exists.

The utility model content:

The utility model is to propose a kind of modern design on the basis of existing technology, simple in structure, easy for operation, can obviously improve the separating effect of husk rice chaff material, reduce the quantity of cracking rice, improve rice milling yield, improve the self-separation rice mill of rice presentation quality, it is achieved by the following technical solution: it mainly comprises the body that is installed on frame, be supported on front-end bearing pedestal, the husk rice main shaft of rear bearing block, feed hopper, rice huller screen, discharging adjustable plate and discharging opening, it is characterized in that: on the husk rice main shaft of feed end, be fitted with draught fan impeller, draught fan impeller together rotates with the husk rice main shaft, the ajutage that is connected in Blower Housing is connected with the rice bran separator box that is installed on discharging opening, during the husk rice operation, paddy is in feed hopper is sent into rice mill, by driven by motor husk rice main axis rotation paddy is ground the system shelling and make rice, the chaff mixture, exhausted most chaff material is after rice huller screen sieves the sorting removal, the rice material backs down the discharging adjustable plate in discharge bucket enters the rice bran separator box, by the ajutage that is communicated in Blower Housing the rice material is carried out the secondary selection by winnowing again and remove chaff, can secretly the residual thorough sorting of minute quantity chaff material impurity that mixes will be carried in the rice material, remove totally, can be by a clean Mi Chengpin who goes out rice bucket outputting high quality.The utility model has the advantages that keeping traditional rice mill and go by rice huller screen on the basis of chaff, again the rice material is sent into and carried out the secondary selection by winnowing in the rice bran separator box and remove chaff, can significantly improve the product quality of rice finished product.

The utility model also has following technical characterictic:

Discharging adjustable plate cunning is led in one group of location guide, is connected on the adjusting screw(rod) of discharging adjustable plate and is set with spring, and the discharging adjustable plate can be easily along one group of location guide slippage, but auto-control grinds pressing pressure and rice output.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment:

The self-separation rice mill that the utility model proposes is implemented by following technical solution: it is that body 21 is installed on frame 1, convertible cover 10 is installed on body 21, be equipped with rice huller screen 20 in the body 21 and by front-end bearing pedestal 3, the husk rice main shaft 6 of rear bearing block 12 supportings, on husk rice main shaft 6, be fitted with husk rice roller 9, be connected in by bolt on the end cap 8 of body 21 feed hopper 7 is installed, in rear bearing block 12, be fitted with discharging adjustable plate 13, discharging adjustable plate 13 is worn and is led on Yu Ergen or three location guides 11, make the discharging adjustable plate 13 can be easily along location guide about 11 steady slippages, be connected on the adjusting screw(rod) 15 of discharging adjustable plate 13 and be set with spring 14, can adapt to the rice output of regulating and control rice mill automatically, 16 places are fitted with rice bran separator box 17 at discharging opening, on the husk rice main shaft 6 of feed end, be fitted with draught fan impeller 4, be connected in by bolt on the Blower Housing 5 of end cap 8 and done front-end bearing pedestal 3, on Blower Housing 5 walls of front-end bearing pedestal 3 positions, done one group of air intake passage 23, the ajutage 22 that is connected in Blower Housing 5 is connected with the rice bran separator box 17 that is installed on discharging opening 16, during rice mill work, draught fan impeller 4 together rotates and can blow in rice bran separator box 17 continuously with husk rice main shaft 6, it is work like this: paddy is sent in the rice mill through feed hopper 7, drive husk rice main shaft 6 rotations that husk rice roller 9 and draught fan impeller 4 are installed through belt pulley 2 by motor, grind system by 9 pairs of paddy of husk rice roller, exhausted most chaff material is after rice huller screen 20 screens out, the rice material backs down discharging adjustable plate 13 in discharge bucket 16 enters rice bran separator box 17, carry out the secondary selection by winnowing again by 22 pairs of rice material of the ajutage that is communicated in Blower Housing 5, after thoroughly carrying the residual minute quantity chaff material that mixes secretly in the sorting rice material and draining by bran output bucket 19, can be by a clean Mi Chengpin who goes out rice bucket 18 outputting high qualities.
