Description

Technical Field

[0001] This utility model relates to screening equipment, specifically a corn screening device. Background Technology

[0002] In the corn processing industry, corn screening is a crucial step, as its effectiveness directly impacts the quality of subsequent processed corn products and production efficiency. Traditional corn screening equipment has revealed numerous problems in practical applications.

[0003] Early corn screening equipment used relatively simple and crude feeding methods, usually relying on manual dumping or simple conveyor belt feeding. Manual dumping not only consumed a lot of manpower, but also made it difficult to accurately control the feeding position, resulting in uneven distribution of corn and affecting screening efficiency. Although simple conveyor belt feeding could reduce the manpower burden to some extent, it was difficult to flexibly adjust the feeding position according to different production needs, and could not meet diverse production scenarios.

[0004] Regarding material conveying and discharge, some equipment lacks effective material concentration and guidance devices. Corn is scattered and disorderly before entering the screening equipment, which can easily cause local blockage of the screen and reduce screening quality. At the same time, there are also many problems in the discharge process. The opening and closing control of the discharge port of some equipment is not precise enough. Either the discharge speed is too fast, causing material to accumulate and affecting the subsequent screening process; or the discharge is not smooth, causing production to stop and seriously affecting production efficiency.

[0024] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.

[0026] The feeding assembly 3 includes a frame 4, a lead screw 5, a guide column 6, a material frame 7, a threaded cylinder 8, a guide cylinder 9, a drive motor 10, a discharge chute 11, a sealing plate 12, a hydraulic cylinder 13, an inclined plate 14, and a triangular block 15. The lead screw 5 is installed in the middle of the inner side of the frame 4, and the material frame 7 is installed on the lead screw 5. The threaded cylinder 8 is provided at the position of the material frame 7 corresponding to the lead screw 5. The discharge chute 11 is symmetrically opened at the bottom end of the material frame 7.

[0027] Vibrating screen 1: The core screening component, which screens corn through vibration, and is fixed to the outside with a support 2.

[0028] Support bracket 2: Supports vibrating screen 1 to ensure stable operation of the equipment, and the top is equipped with feeding component 3.

[0029] Feeding component 3

[0030] Frame 4: The main frame of the feeding component 3.

[0031] Lead screw 5: Installed in the middle of the inner side of the frame 4, it drives the material frame 7 to move by rotating.

[0032] Guide columns 6: symmetrically fixed on both sides of the lead screw 5, providing guidance for the movement of the material frame 7.

[0033] Material frame 7: Used to hold corn to be screened. Threaded cylinder 8 is set at the position corresponding to screw 5, and guide cylinder 9 is set at the position corresponding to guide column 6.

[0034] Threaded cylinder 8: works with lead screw 5 to enable the material frame 7 to move along lead screw 5.

[0035] Guide cylinder 9: Sleeve onto guide column 6 to make material frame 7 move smoothly.

[0036] Drive motor 10: Installed at one end of lead screw 5, providing power for the rotation of lead screw 5.

[0037] Discharge chute 11: Located at the bottom of the material frame 7, used to discharge corn.

[0038] Sealing plate 12: It is slidably connected to the material frame 7 at the bottom of the discharge chute 11 to control the opening and closing of the discharge chute 11.

[0039] Hydraulic cylinder 13: Installed on one side of the sealing plate 12, with one end fixed to the bottom wall of the frame 4, driving the sealing plate 12 to slide.

[0040] Inclined plate 14: Located on both sides of the inner side wall of the material frame 7, it guides the corn to move towards the discharge chute 11.

[0041] Triangular block 15: Located inside the material frame 7, below the threaded cylinder 8, with its bottom edge flush with the discharge chute 11, to assist in the discharge of corn.

[0042] Working principle: Feeding preparation and movement positioning: Before starting the screening operation, the operator starts the drive motor 10; the drive motor 10 serves as the power source for the rotation of the lead screw 5, and its output rotational power is transmitted to the lead screw 5. Since the threaded cylinder 8 on the material frame 7 is tightly fitted with the lead screw 5, and the guide cylinder 9 is sleeved on the guide posts 6 on both sides of the lead screw 5, this structure enables the material frame 7 to move in a straight line along the lead screw 5 when the lead screw 5 rotates, and accurately move to the pre-set feeding position;

[0043] Feeding process and material concentration guidance: When the material frame 7 reaches the designated feeding position, the operator pours the corn to be screened into the material frame 7; at this time, the inclined plates 14 installed on both sides of the inner side wall of the material frame 7 and the triangular blocks 15 located below the threaded cylinder 8 begin to play their role; the inclination angle of the inclined plates 14 is carefully designed to guide the corn to flow towards the discharge chute 11 under the action of gravity; the triangular blocks 15 further assist the corn to concentrate and gather, so that the corn gradually gathers near the discharge chute 11 in the material frame 7, preparing for subsequent discharge;

[0044] Discharge control and material conveying: When corn needs to be discharged into the vibrating screen 1 for screening, the hydraulic cylinder 13 is activated. The hydraulic cylinder 13 is connected to the sealing plate 12, and one end of it is fixed to the bottom wall of the frame 4. When the hydraulic cylinder 13 is working, the piston rod pushes the sealing plate 12 to slide along the discharge chute 11 at the bottom of the material frame 7 through extension and retraction, thereby opening the discharge chute 11. At this time, the corn concentrated near the discharge chute 11 is discharged from the discharge chute 11 under the action of gravity and enters the vibrating screen 1. It is worth mentioning that during the discharge process, the drive motor 10 works continuously, driving the lead screw 5 to rotate continuously, so that the material frame 7 moves continuously along the lead screw 5. This dynamic movement process allows the material in the material frame 7 to fall evenly from the discharge chute 11 onto the vibrating screen 1, effectively avoiding material accumulation and greatly improving the screening effect and screening efficiency of the vibrating screen 1.

[0045] Beneficial effects: Precise positioning and efficient feeding: Through the coordinated operation of drive motor 10, lead screw 5, threaded cylinder 8, guide column 6, and guide cylinder 9, material frame 7 can move precisely to the preset feeding position, which greatly improves the accuracy and efficiency of feeding and reduces the error and time cost of manual operation.

[0046] Material concentration and smooth discharge: The ingenious design of the inclined plate 14 and triangular block 15 inside the material frame 7 effectively guides the corn to concentrate near the discharge chute 11, making full preparation for discharge. At the same time, the hydraulic cylinder 13 drives the sealing plate 12 to control the opening and closing of the discharge chute 11, making the discharge process controllable and smooth, avoiding problems such as material blockage.

[0047] Uniform material distribution and efficient screening: During the discharge process, the drive motor 10 works continuously to move the material frame 7, so that the material can fall evenly from the discharge chute 11 onto the vibrating screen 1, effectively avoiding material accumulation, significantly improving the screening effect and screening efficiency of the vibrating screen 1, and ensuring the quality and output of corn screening.

[0048] Stable structure and reliable operation: The support frame 2 firmly supports the vibrating screen 1, while the components of the feeding assembly 3 work closely together and coordinate with each other. The overall equipment structure is stable and the operation is reliable, which reduces the probability of equipment failure, lowers maintenance costs, and improves the service life of the equipment.

[0049] Easy to operate and highly controllable: Every step of the screening process, whether it is adjusting the feeding position, controlling the discharge, or starting the screening operation, is achieved through power components such as motors and hydraulic cylinders. The operation is simple and easy to control, which reduces the labor intensity of operators and improves the controllability and safety of the production process.
