Description

Technical Field

[0001] This utility model relates to the field of screening machines, specifically a bean sprout screening machine. Background Technology

[0002] The process of separating loose materials into different particle sizes by passing them through one or more screens is called screening. A screening machine is a vibrating screening machine that uses the relative motion between the loose material and the screen surface to allow some particles to pass through the screen holes, separating materials such as sand, gravel, and crushed stone into different grades according to particle size. The screening process is generally continuous. After the raw material is fed onto the screening machine (referred to as the screen), materials smaller than the screen hole size pass through the screen holes and are called undersize products; materials larger than the screen hole size are continuously discharged from the screen surface and are called oversize products. The particle size classification depends on the screen surface, which is divided into three types: grate screens, plate screens, and mesh screens. Screening machines utilize the differences in material size and mass, as well as the different settling velocities of liquids, to allow smaller and larger materials to settle to the bottom of the tank.

[0003] For example, according to patent application CN 208082843 U, a feed pellet screening machine includes a screening support mechanism, a screening mechanism, and a feed feeding mechanism. The screening support mechanism includes a screening support frame, an auxiliary support frame, a feeding hopper, a fine particle collection box, a standard particle collection box, and a defective particle collection box. The screening mechanism includes a vibration generator, a feed screening box, a feeding slide, and multiple buffer components. The feed feeding mechanism includes a feeding hopper and a hopper cover, with the hopper cover hinged to the feeding hopper. The feeding hopper is connected to the screening shell. By setting up the screening support mechanism, screening mechanism, and feed feeding mechanism, the feed enters the screening mechanism from the feed feeding mechanism. The vibration generator on the screening mechanism drives the feed pellets to vibrate, and the screening mesh screens feed pellets of different sizes, resulting in uniform pellets in each batch of feed and improving feed quality.

[0004] Because bean husks remain on bean sprouts after they grow, they need to be separated during processing. Current methods mostly involve manual washing and separation, which is quite troublesome. Therefore, there is an urgent need in the market to develop a bean sprout screening machine to help people solve this problem. Utility Model Content

[0005] The purpose of this utility model is to provide a bean sprout screening machine to solve the problem mentioned in the background art that after the bean sprouts grow, the bean shells will remain on the bean sprouts, so the bean shells need to be separated during the processing of bean sprouts. The existing methods mostly rely on manual washing and separation, which is quite troublesome.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bean sprout screening machine, comprising a screening machine, wherein a screening trough is provided at the upper end of the screening machine, a conical bucket is fixedly connected to the lower end of the screening machine, a lower cover plate is openably connected to the lower end of the conical bucket, wing plates are fixedly connected to both sides of the front and rear end faces of the screening machine, and support columns are connected to the lower ends of the wing plates, a first fixed plate and a second fixed plate are fixedly connected to the upper and lower ends of one side face of the screening machine respectively, a screw is rotatably connected between the first fixed plate and the second fixed plate, a lifting plate is connected to the middle of the screw, a screen is rotatably connected to the lower end of the screening trough, and a vibration motor is fixedly connected to the middle of the front and rear sections of the conical bucket.

[0007] Preferably, a support spring is provided between the upper end of each support column and the lower end of the wing plate, and the four support columns are fixedly connected by a connecting rod.

[0008] Preferably, the upper end of the support spring is fixedly connected to the lower end of the wing plate, and the lower end of the support spring is fixedly connected to the upper end face of the support column.

[0012] Preferably, the lower end of one side of the screen is rotatably connected to the screening machine inside the screening trough via a rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting up a sieve, a sieve trough is set at the upper end of the sieve machine, and a sieve is rotatably connected to the lower end of the sieve trough. The sieve machine is driven by a vibrating motor to vibrate and sieve the bean sprouts, so that the small-diameter bean shells pass through the sieve under the action of vibration and fall into the conical hopper for collection, while the large-diameter bean sprouts are blocked on the sieve, thus realizing the separation of bean sprouts and bean shells.

[0015] 2. In this utility model, by setting support springs, a support spring is set between the upper end of each support column and the lower end of the wing plate. The four support columns are fixedly connected by connecting rods. The upper end of the support spring is fixedly connected to the lower end of the wing plate, and the lower end of the support spring is fixedly connected to the upper end face of the support column. This allows the screening machine to vibrate on the four support columns under the drive of the vibrating motor to screen the bean sprouts. At the same time, the support springs isolate vibration between the support columns and the screening machine.

[0016] 3. In this utility model, a lifting plate is provided, and a screw is rotatably connected between the first fixed plate and the second fixed plate. The lifting plate is connected to the middle of the screw, and a threaded hole is provided on the lifting plate. The middle of the screw is threadedly connected to the threaded hole, so that when the screw rotates, it drives the lifting plate to rise and fall. One end of the lifting plate extends through the rectangular opening to one side of the lower end of the screen. When the lifting plate rises, it slides along the rectangular opening. When the lifting plate rises, it lifts one side of the screen, so that the screen is tilted inside the screening trough by rotating the rotating shaft. After the bean sprout powder is screened, the bean sprouts can be discharged and collected from one side of the screening machine by tilting the screen and opening the side baffle.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a bean sprout screening machine, including a screening machine 1. The upper end of the screening machine 1 has a screening trough 101, and the lower end of the screening machine 1 is fixedly connected to a conical hopper 102. Small-diameter bean shells pass through the screen 5 under vibration and fall into the conical hopper 102 for collection. The lower end of the conical hopper 102 is openable and connected to a lower cover plate 103 for easy processing of the bean shells. Wing plates 104 are fixedly connected to both sides of the front and rear end faces of the screening machine 1. 4. Support columns 2 are connected to the lower end of each of the four sections. The first fixed plate 3 and the second fixed plate 301 are fixedly connected to the upper and lower ends of one side end face of the screening machine 1, respectively. A screw 302 is rotatably connected between the first fixed plate 3 and the second fixed plate 301. A lifting plate 4 is connected to the middle of the screw 302. A screen 5 is rotatably connected to the lower end of the screening trough 101. A vibrating motor 107 is fixedly connected to the middle of the front and rear sections of the conical bucket 102. The vibrating motor 107 drives the screening machine 1 to vibrate.

[0024] Furthermore, a support spring 201 is provided between the upper end of each support column 2 and the lower end of the wing plate 104, and the four support columns 2 are fixedly connected by connecting rods.

[0025] Furthermore, the upper end of the support spring 201 is fixedly connected to the lower end of the wing plate 104, and the lower end of the support spring 201 is fixedly connected to the upper end face of the support column 2, so that the screening machine 1 can vibrate on the four support columns 2 under the drive of the vibrating motor 107 to screen the bean sprouts. At the same time, the support spring 201 isolates the vibration between the support column 2 and the screening machine 1.

[0026] Furthermore, the lower end of the screw 302 extends through the second fixing plate 301 and is fixedly connected to a turntable 303. The screw 302 rotates by rotating the turntable 303.

[0027] Furthermore, the lifting plate 4 is provided with a threaded hole 401, and the middle part of the screw 302 is threadedly connected to the threaded hole 401, so that when the screw rotates, it drives the lifting plate 4 to rise and fall.

[0028] Furthermore, a rectangular opening 105 is provided in the middle of one end face of the screening machine 1 and between the first fixed plate 3 and the second fixed plate 301. One end of the lifting plate 4 extends through the rectangular opening 105 to the lower end of the screen 5 and slides along the rectangular opening 105 when it rises.

[0029] Furthermore, the lower end of one side of the screen 5 is rotatably connected to the sieve machine 1 inside the sieve trough 101 via the rotating shaft 501. When the lifting plate 4 rises, it lifts one side of the screen 5, causing the screen 5 to rotate and tilt inside the sieve trough 101 via the rotating shaft 501. After the bean sprout powder is sieved, the bean sprouts can be discharged and collected from one side of the sieve machine 1 by tilting the screen 5 and opening the side baffle 106.

[0030] Working Principle: During operation, the screening machine 1 is securely mounted on the upper part of a frame composed of support columns 2. A support spring 201 is cleverly installed between each support column 2 and the wing plate 104. This design not only ensures the stability of the screening machine 1 during vibration but also effectively isolates the transmission of vibration to the support structure through the buffering effect of the spring, reducing noise and mechanical wear. The screening process begins with the bean sprout raw material being evenly spread on the screen 5 within the screening trough 101. At this time, the vibration motors 107 installed on the front and rear sides of the conical hopper 102 begin to operate. The strong vibrations they generate are transmitted to the screen 5 through the overall structure of the screening machine 1, causing the bean sprouts and bean shells on the screen to be subjected to continuous impact and shaking. During this process, smaller-diameter bean shells, due to their light weight and ease of movement under force, quickly pass through the holes of the screen 5 and fall into the conical hopper 102 below. The conical hopper design facilitates the collection and centralized processing of these screened impurities, while the openable design of the lower cover plate 103 further facilitates cleaning. As the screening process continues, bean sprouts are gradually separated and left on the screen. Once the screening achieves the desired effect, the operator can activate the screen tilting mechanism by operating the turntable 303. The rotation of the turntable 303 drives the connected screw 302 to rotate, and the screw 302 is tightly engaged with the threaded hole 401 on the lifting plate 4. As the screw rotates, the lifting plate 4 slowly rises along the rectangular opening 105 on the side of the screening machine 1, and its end gradually lifts one side of the screen 5. During this process, the screen 5 tilts slowly inside the screening trough 101 with the rotating shaft 501 as the fulcrum until it reaches a suitable angle. At this time, the side baffle 106 is opened, and the screened bean sprouts can slide smoothly down the tilted screen 5 to one side of the screening machine 1 under the action of gravity, facilitating subsequent collection and processing. The entire process is not only efficient and fast, but also easy to operate, greatly improving the efficiency and accuracy of bean sprout screening.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
