Abstract
The utility model relates to a cracking-proof screen sheet for a rice mill. The cracking-proof screen sheet for a rice mill is formed by that a cracking-proof groove is respectively arranged on both sides of a screen sheet by using the structural style of the existing screen sheet. The length of the groove is shorter than the length of the screen sheet for 10-20 mm. The depth of the groove is 1-4 mm. The width B of the groove is 10-40 mm. The included angle of the centerline of the groove and the plane of the Screen sheet is 20 DEG-40 DEG. The utility model has the advantages of novel design, simple structure, easy processing and easy manufacture. The utility model solve the problem that the existing rice mill has a short service life.
Description
The utility model relates to the parts of rice mill, refers in particular to a kind of sieve sheet (watt sieve) of rice mill.
The sieve sheet that uses on the existing rice mill, its service life is not long, do not reach the normal wear phase just cracking scrap, not only increased the processing cost of rice, and made troubles to production.Its reason that ftractures easily is: the unreasonable structure of sieve sheet, the sieve sheet is unbalance stress in the course of the work, the insufficient strength of sieve sheet.Therefore, be necessary existing sieve sheet is improved.
The purpose of this utility model provides a kind of rice mill anticracking sieve sheet, and it has modern design, and is simple in structure, and processing and manufacturing is easy to advantage.
The technical scheme of the utility model screen sieves of rice mill is such: it utilizes the version of existing sieve sheet, respectively sets up a stress relieving grooving in sieve sheet two sides, and the length of groove is than the short 10-20mm of sieve leaf length; The degree of depth of groove is 1-4mm.The width of groove is 10-40mm, and the center line of groove is 20-40 ° with the angle of sieve plate plane.
Below in conjunction with accompanying drawing the utility model is carried out detailed narration:
Accompanying drawing 1 is a perspective view of the present utility model.
Accompanying drawing 2 be among Fig. 1 A-A to cutaway view.
Shown in 1,2, the utility model screen sieves of rice mill is to improve to form on the architecture basics of existing sieve sheet with reference to the accompanying drawings.Its invention main points are: the both sides at sieve sheet (watt sieve) respectively are provided with a stress relieving grooving E, the length 1 of groove E is than the short 10-20mm of the length L of sieve sheet, the dark h of groove E is 1-4mm, and the width B of groove E is 10-40mm, and the center line of groove E is 20 °-40 ° with the angle α on sieve plane.
This design of the utility model screen sieves of rice mill has solved the problem that existing sieve sheet in use ftractures easily.In the process of producing the sieve sheet, whether carry out material heat treatment, all can prolong the service life of sieve sheet.For example 6NF9 type rice mill uses the husk rice amount of existing sieve sheet to be 6000kg, will scrap.Use the husk rice amount of the utility model sieve sheet to be 75000kg.The utility model sieve sheet is than having improved 12.5 times the service life of existing sieve sheet.
The utility model cracking-proof screen sheet for rice mill has modern design, and is simple in structure, Processing and manufacturing is easy to advantage. It solves short the asking in service life of existing rice mill Topic.
