Background technique

Flour sieves are often used in the kitchen to sieve powdery materials such as potato starch, corn starch, wheat starch, flour, and tapioca starch. The traditional powder sieve is cylindrical, and the bottom of the barrel is made of screen mesh. When sieving, it is necessary to shake the powder sieve continuously by hand or tap the wall of the powder sieve with the other hand to make the powder continuously fall. However, when the traditional powder sieve is thicker, the powder cannot be sieved and dropped effectively and quickly. It is inconvenient to operate with two hands during operation.

Contents of the invention

The circular turntable on the top, the stirring blades are evenly spaced on the circular turntable, the middle of the screen is provided with a circular mounting plate, and the fixed bracket includes a fixed plate in the middle and support rods evenly spaced around the fixed plate. The inner cylinder wall of the screen cylinder is fixed, the two ends of the rotating shaft are fixed on the installation plate and the fixed plate, and the drive assembly is connected with the circular turntable; the drive assembly includes a round wheel fixed with the circular turntable, and the Located between the circular turntable and the fixed plate, an annular groove is provided on the side wall of the circular wheel. The handle is C-shaped, and a wrench arranged in a vertical shape is arranged on the handle. The upper end of the wrench is hingedly connected with the handle along the horizontal direction. Flexible pull rope, one end of the pull rope is fixedly connected to the round wheel, the other end of the pull rope passes through the barrel wall of the screen drum and is connected to the lower end of the wrench, and there is a device between the round wheel and the fixed plate to drive the stirring assembly to rotate in reverse The first torsion spring is provided, and the second torsion spring for driving the wrench to rotate in reverse is arranged between the wrench and the handle.

In the above technical solution, the stirring component is used to stir the powder so that it can quickly pass through the screen, which facilitates the distribution of the material and solves the problem that the powder is too thick to be sieved.

detailed description

In order to make the objects and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with examples. It should be understood that the following words are only used to describe one or several specific implementation modes of the present invention, and do not strictly limit the protection scope of the specific claims of the present invention.

The present invention adopts the following technical solutions for implementation. A kitchen flour sieve includes a cylindrical sieve cylinder 21. The bottom of the sieve cylinder 21 is formed by a screen 22. A handle 23 is arranged on the outer cylinder wall of the sieve cylinder 21. The bottom of the barrel 21 is provided with a stirring assembly, which includes stirring blades 12, which are rotatably fixed on the sieve cylinder 21, the rotating surface of the stirring blades 12 is arranged parallel to the screen 22, and the driving assembly is connected with the stirring assembly. In the above technical solution, the stirring component is set to stir the material powder so that it can pass through the screen 22 quickly, which is convenient for material distribution and solves the problem that the material powder is too thick to be sieved.

A specific solution is that the distance between the stirring blade 12 and the screen 22 is 2-3 mm. A fixed bracket is arranged above the stirring assembly, the stirring assembly includes a rotating shaft 15 and a circular turntable 11 fixed on the rotating shaft 15, the stirring blades 12 are evenly spaced on the circular turntable 11, and the middle part of the screen 22 is provided with a circular mounting The fixed bracket includes a fixed plate 13 in the middle and support rods 14 evenly spaced around the fixed plate 13. The support rods 14 are fixedly connected to the inner wall of the screen cylinder 21, and the two ends of the rotating shaft 15 are fixed on the mounting plate and fixed On the plate 13, the drive assembly is connected with the circular turntable 11. The driving assembly includes a round wheel 16 fixedly connected with the round turntable 11. The round wheel 16 is located between the round turntable 11 and the fixed plate. An annular groove is arranged on the side wall of the round wheel 16. The handle 23 is C-shaped. A wrench 24 arranged vertically is provided, the upper end of the wrench 24 is hingedly connected with the handle 23 along the horizontal direction, a flexible stay cord 17 is arranged in the annular groove, one end of the stay cord 17 is fixedly connected to the round wheel 16, and the other end of the stay cord 17 One end is connected to the lower end of the wrench 24 through the bucket wall of the screen drum 21, and the first torsion spring 31 for driving the stirring assembly in the opposite direction (the opposite direction to which the driving assembly drives the rotation) is arranged between the round wheel 16 and the fixed plate, A second torsion spring 32 is arranged between the wrench 24 and the handle 23 for driving the wrench 24 to rotate in reverse. In the above technical solution, by pulling the wrench 24, the pull rope 17 pulls the stirring assembly to rotate, so that the material powder falls quickly, and the first and second torsion springs 31, 32 make the stirring assembly reversely rotate, thereby carrying out reciprocating stirring. 4 to 6 stirring blades 12 are arranged, and the circular wheel and the circular turntable are arranged at the same core.

Because the stirring of the stirring blade 12 will produce a certain pressure on the powder, which may cause the powder to agglomerate, therefore, the present invention adopts the following technical scheme for further implementation. The stirring blade 12 is composed of a V-shaped plate with an upward cross-sectional opening, and the plate The size of the V-shaped jaw (the jaw points to the side away from the screen) is 150-160°, and the corner of the lower plate surface of the plate is an arc transition, preferably θ=155°. When such agitating blade 12 rotates positively and negatively, the outer surface of the agitating blade 12 can push the material powder obliquely downward, so that the material powder can be quickly sieved and dropped, ensuring reliable sieving, and at the same time, the resistance it suffers is small, The operating force required to move the wrench 24 is relatively small.

The above is only a preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, after knowing the content recorded in the present invention, they can also make changes to it without departing from the principle of the present invention. Several equivalent transformations and substitutions should also be deemed to belong to the protection scope of the present invention.
