Description

Technical Field

[0001] The utility model relates to the technical field of wheat production, in particular to a screening device for wheat flour production. Background Art

[0002] Wheat is a general term for plants of the genus Triticeae. The representative species is common wheat, which is a plant of the Poaceae family and a cereal crop widely grown throughout the world. Wheat is one of the staple foods of mankind. After being ground into flour, it can be used to make bread, steamed buns, biscuits, noodles and other foods. It is one of the important sources of food.

[0003] For example, a wheat flour grading and screening device disclosed in publication number CN219965501U screens the wheat flour and then discharges the flour through a vibrator. When in use, the cleaning device is started and the sweeping rod is rotated so that the bristles on the sweeping rod can clean the wheat flour remaining on the first and second sieves.

[0004] However, the screening structure can only be used to vibrate and discharge materials through an exciter during use. When wheat flour is directly accumulated on the surface of the screen, the raw materials cannot be stirred, which will cause blockage inside the screen cylinder and affect the feeding work. In view of this, we propose a screening device for wheat flour production. Summary of the invention

[0005] The purpose of the utility model is to provide a screening device for wheat flour production to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a screening device for wheat flour production, comprising a screening box, a U-shaped frame is fixedly installed at the lower end of the screening box, a screen is fixedly installed on the inner wall of the screening box, a feed pipe is fixedly installed on both sides of the upper end of the screening box, and a screening structure is arranged inside the screening box, and the screening structure comprises:

[0014] Compared with the prior art, the utility model provides a screening device for wheat flour production, which has the following beneficial effects:

[0015] 1. The screening device for wheat flour production is equipped with a screening structure to accelerate the discharge of wheat flour when it is screened inside the screening box. The user can start the motor to drive the rotating shaft to rotate, and the rotation of the rotating shaft drives multiple groups of stirring rods on its surface to rotate to stir the wheat flour. When the rotating shaft rotates, it will drive the central gear on its surface to rotate, and the three groups of rotating rods at its lower end to rotate in the opposite direction through the rotation of the circular frame. When the rotating rod rotates, it will also drive the stirring plate on its side wall to rotate to turn the raw materials over and discharge them, thereby avoiding blockage inside the screening box and affecting the discharge work.

[0016] 2. The screening device for wheat flour production is provided with a cleaning structure to facilitate cleaning of the wheat flour adhered to the inner wall of the screening box. When the wheat flour accumulated inside the screening box has been partially screened out or completely screened for cleaning, the user can increase the power of the motor so that the motor output shaft drives the rotating shaft to accelerate the rotation. At this time, the stretching rod moves outward under the action of centrifugal force. At this time, the moving stretching rod will bring the scraper close to the surface of the screening box. At this time, the rotating shaft will drive the scraper to scrape the inner wall of the screening box, thereby preventing some wheat flour from adhering to the inner wall of the screening box and unable to fall off.

A central gear 35 is fixedly mounted on the surface of the shaft 34, an annular tooth groove 36 is fixedly mounted on the inner wall of the circular mouth 32, a rotating rod 333 is fixedly mounted on the inner wall of the screening box 1, a transmission gear 334 is fixedly mounted on the surface of the rotating rod 333, a rotating rod 37 is rotatably connected to the lower end of the circular frame 31, a rotating gear 38 is fixedly mounted on the upper end surface of the rotating rod 37, a plurality of groups of stirring plates 39 are fixedly mounted on the surface of the rotating rod 37, an annular gear ring 310 is fixedly mounted on the inner wall of the screening box 1, a plurality of groups of stirring rods 311 are fixedly mounted on the side wall of the rotating shaft 34, and a cleaning structure 4 is arranged inside the stirring rod 311.

[0024] Specifically, the screening structure 3 of the technical solution of the utility model includes: a circular frame 31, a circular mouth 32, a motor 33, a rotating shaft 34, a central gear 35, an annular tooth groove 36, a rotating rod 37, a rotating gear 38, a stirring plate 39, an annular gear ring 310, and a stirring rod 311.

[0025] In one embodiment of the utility model, a screening structure 3 is provided to accelerate the discharge of wheat flour when it is screened inside the screening box 1. The screening box 1 is provided to store wheat flour, and a screen is fixedly installed at the lower end of the screening box 1 for screening. When in use, the user can first add the raw materials through two sets of feeding pipes 5, and then the wheat flour will be screened through the screen and piled to a certain extent. At this time, the user can start multiple sets of vibrators 7 to make the inner wall of the screening box 1 and the screen vibrate to a certain extent to accelerate the screening and discharge. At the same time, the user can start the motor 33 to work, and the output shaft of the motor 33 drives the rotating shaft 34 to rotate, and the rotation of the rotating shaft 34 drives the multiple sets of stirring rods 311 on its surface to rotate to stir the wheat flour.

[0026] When the rotating shaft 34 rotates, the central gear 35 on its surface will be driven to rotate. The rotation of the central gear 35 will drive the transmission gear 334 meshing with it to rotate. At this time, the annular tooth groove 36 meshing with the transmission gear 334 will drive the circular frame 31 on its side wall to rotate. The rotation of the circular frame 31 drives the three groups of rotating rods 37 at its lower end to rotate in the opposite direction. When the rotating rod 37 rotates, the meshing of the rotating gear 38 at its upper end and the annular gear ring 310 causes it to rotate on its own.

[0027] By providing a cleaning structure 4, it is convenient to clean the wheat flour adhered to the inner wall of the screening box 1. When the wheat flour accumulated inside the screening box 1 has been partially screened out or completely screened for cleaning, the user can increase the power of the motor 33 so that the output shaft of the motor 33 drives the rotating shaft 34 to rotate faster. At this time, the stirring rod 311 on the side wall of the rotating shaft 34 will also rotate faster. At this time, the stretching rod 44 inside the stirring rod 311 moves outward under the action of centrifugal force and stretches the stretching spring 42. At this time, the moving stretching rod 44 will bring the scraper 45 on its side wall close to the inner wall surface of the screening box 1. At this time, the rotating rotating shaft 34 will drive the scraper 45 to scrape the inner wall of the screening box 1, thereby preventing some wheat flour from adhering to the inner wall of the screening box 1 and unable to fall off.

[0028] Please continue reading Figure 1-Figure 5The cleaning structure 4 includes a notch 41 opened on the side wall of the stirring rod 311, one end of a stretching spring 42 is fixedly installed on the inner wall of the notch 41, and a slide plate 43 is fixedly installed on the other end of the stretching spring 42, one end of a stretching rod 44 is fixedly installed on the side wall of the slide plate 43, and a scraper 45 is fixedly installed on the other end of the stretching rod 44, and the end of the scraper 45 away from the stretching rod 44 is arranged in an arc structure, and three groups of rotating rods 37, stirring plates 39 and rotating gears 38 are arranged, and the three groups of rotating rods 37, stirring plates 39 and rotating gears 38 are all arranged at the lower end of the round frame 31, a collecting box 6 is fixedly installed at the lower end of the U-shaped frame 2, and multiple groups of vibrators 7 are fixedly installed on both sides of the lower end of the screening box 1.

[0029] During operation, the user can first add the raw materials through the two groups of feeding pipes 5, and then the wheat flour will be screened through the screen and fall into the collecting box 6. At this time, the multiple groups of vibrators 7 are started to make the inner wall of the screening box 1 and the screen vibrate to a certain extent to accelerate the screening and feeding, and then the motor 33 is started to work, and the output shaft of the motor 33 drives the rotating shaft 34 to rotate, and the rotation of the rotating shaft 34 drives the multiple groups of stirring rods 311 to rotate, and the rotation of the rotating shaft 34 will drive the central gear 35 to rotate, and the rotation of the central gear 35 will drive the transmission gear 334 meshed with it to rotate, and at this time, the annular tooth groove 36 meshed with the transmission gear 334 will drive the round frame 31 of its side wall to rotate, and the rotation of the round frame 31 drives the three groups of rotating rods 37 at its lower end to rotate in the opposite direction, and the rotating rod 3 When 7 rotates, the rotating gear 38 at its upper end is meshed with the annular gear ring 310 so as to rotate by itself. The rotating rod 37 will also drive the multiple groups of stirring plates 39 on its side wall to rotate by themselves to turn over and discharge the raw materials inside the screening box 1.
