Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flour sieves, in particular to a flour inspection sieve with high efficiency. Background Art
[0002] Flour is a powdered food raw material obtained by grinding, screening and other processing procedures of cereals or beans. Common flour mainly comes from cereals such as wheat, corn, rice, oats, and beans such as soybeans and mung beans. Flour is the basic raw material for many food productions and is widely used in baking, cooking and making various foods such as bread, biscuits, pastries, noodles, etc.
[0003] Before packaging the flour, it is necessary to use a flour inspection sieve to screen out large particles of impurities in the flour. However, when the existing inspection sieve is used, the flour is fixed on one place on the sieve, resulting in the flour being concentrated in one place on the sieve. The flour needs to be gradually dispersed as the sieve shakes, which results in low screening efficiency and affects the benefits of the enterprise. Utility Model Content
[0004] The utility model aims to provide a flour inspection sieve with high efficiency which can prevent flour from being concentrated and falling on one place of the sieve and improve the screening efficiency.
[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.
[0006] A high-efficiency flour inspection screen includes a box body, a material tank is installed on the top of the box body, a feed pipe is installed on the bottom of the material tank, and the feed pipe is connected to the top of the box body, a plug valve is arranged on the outside of the feed pipe, a feed pipe is arranged on the top of the material tank, and a sealing cover is installed on the end of the feed pipe. A receiving hopper is arranged inside the box body, and the receiving hopper is a structure that is wide at the top and narrow at the bottom. A slide groove is opened along the length direction of the top wall of the box body, and a slider is installed on the upper surface of the receiving hopper, and the end of the slider is arranged in the slide groove. A driving mechanism that can drive it to reciprocate along the length direction of the box body is arranged on the rear side of the receiving hopper. A screen is installed on the lower side of the receiving hopper inside the box body, and a collection box is arranged on the lower side of the screen inside the box body. A handle is arranged on the outer surface of the collection box, and a box door is hingedly installed on the outer side of the box body, and a lock is arranged on the box door. A vibration motor is installed on the side surface of the box body.
[0007] It can be seen that by first pouring the flour into the material tank and closing the sealing cover, and then opening the gate valve, the flour can fall onto the screen for screening, and the screened flour falls into the collecting box for collection, thereby reducing the diffusion of dust during the screening process and providing a good working environment for workers. The driving mechanism drives the receiving hopper to reciprocate. Since the receiving hopper is a structure that is wide at the top and narrow at the bottom, the receiving hopper can still receive the flour falling from the feeding pipe when it moves to the side. Therefore, during the reciprocating motion of the receiving hopper, the flour can be evenly sprinkled on the screen from its bottom, avoiding the situation where the flour is concentrated in one place, and improving the screening utilization rate of the screen, thereby achieving the purpose of improving the screening efficiency.
[0008] Furthermore, the driving mechanism includes a first rotating motor installed on the rear side of the box body, the end of the output shaft of the first rotating motor passes through the interior of the box body and is installed with a disc, a lever is installed on the side of the outer surface of the disc away from its center, and a fixed plate is installed on the rear side of the hopper, a limiting groove is opened inside the fixing plate, and the end of the lever is arranged in the limiting groove.
[0009] When the first rotating motor is started, its output shaft drives the disc to rotate. Since the receiving hopper is slidably connected to the top wall of the box body through the sliding groove and the slider, the disc can drive the lever to push the inner wall of the limiting groove, thereby achieving the purpose of driving the receiving hopper to reciprocate.
[0010] Furthermore, two sleeves are installed on the outer surface of the feeding pipe, and striking rods are inserted into the inside of the two sleeves. The inner wall of the sleeve is provided with an inner groove, and the outer surface of the striking rod is provided with a shoulder. The outer surface of the striking rod is sleeved with a telescopic spring, and the two ends of the telescopic spring are respectively abutted against the shoulder and the inner wall of the inner groove. A connecting plate is commonly installed at one end of the two striking rods, and a second rotating motor is installed on the upper surface of the box body, and a cam is installed at the end of the output shaft of the second rotating motor.
[0011] In order to avoid blockage of flour when falling inside the discharge pipe, the second rotating motor can be started, and the second rotating motor can drive the cam to rotate rapidly. When the convex surface of the cam squeezes the connecting plate, the connecting plate can be pushed to move, thereby driving the two striking rods to move toward the direction of the discharge pipe at the same time and strike its surface. Vibration is generated by hitting the discharge pipe, so that the flour inside the discharge pipe can be shaken apart, thereby improving its falling efficiency and avoiding blockage. The end of the striking rod hits the discharge pipe and generates a reaction force. Combined with the elastic force of the compressed telescopic spring, the striking rod can be driven to drive the connecting plate to quickly reset, thereby driving the striking rod to hit the discharge pipe in the gap during the rotation of the cam, thereby avoiding blockage inside the discharge pipe.
[0012] Furthermore, two support rods are arranged on both sides of the box body, two cross bars are installed on the outer surfaces of both sides of the box body, shock-absorbing springs are arranged on the tops of the support rods, and the ends of the shock-absorbing springs are connected to the cross bars.
[0013] By arranging the support rod, the cross rod and the shock absorbing spring, the entire device can be buffered and protected when the vibration motor is started, thereby increasing the service life.
[0014] Furthermore, a groove is provided on the surface of the box body, and a sealing strip is provided inside the groove.
[0015] By setting the sealing strip, the sealing between the box body and the box door can be improved after the box door is closed, avoiding dust leakage and causing environmental pollution.
[0016] Furthermore, a through slot is provided on the connecting plate, and a guide wheel is rotatably installed inside the through slot.
[0017] By setting the through slot, when the cam rotates, it can drive the through slot to rotate, thereby reducing the friction between the cam and the through slot, making the movement smoother.
[0018] Furthermore, enclosure plates are installed on four sides of the upper surface of the screen.
[0019] By setting the enclosure, the flour can be blocked to prevent the flour from falling from the edge of the screen without being screened, thus affecting the screening quality.
[0020] Furthermore, a silicone pad is provided at the other end of the striking rod.
[0021] By setting the silicone pad, when the striking rod hits the discharge pipe, not only the noise can be reduced, but also the impact force on the discharge pipe can be reduced, thereby avoiding the situation where the surface of the discharge pipe is dented. BRIEF DESCRIPTION OF THE DRAWINGS
