Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening equipment technology, and in particular to a screening device. Background Technology
[0002] Screening devices utilize the relative motion between bulk materials 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 particle size classification depends on the screen surface, which is available in three types: grate, plate screen, and mesh screen. Grate screens are suitable for screening large particles. Plate screens are made of perforated steel plates with round, square, or rectangular holes, have a long service life, are not easily clogged, and are suitable for screening medium-sized particles. Mesh screens are made of woven or welded steel wire with square, rectangular, or elongated holes. Elongated mesh holes are suitable for screening moist materials. The advantage of mesh screens is their larger effective area.
[0003] Currently, a large amount of sand is needed during home renovation. This sand needs to be screened to remove larger particles. When the screening device is used, workers need to shovel sand and manually feed it, which is very laborious and troublesome. Utility Model Content
[0004] The main objective of this invention is to provide a screening device that can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a screening device, including a base, a screening mechanism installed on the upper part of the base, a conveying mechanism fixedly connected to one side of the base by a bracket, and the upper discharge port of the conveying mechanism being located on the upper part of the screening mechanism;
[0006] The conveying mechanism includes a frame, two rollers, a conveyor belt, multiple buckets, and a geared motor. The frame is mounted on one side of the upper part of the base via a bracket in the middle. The front and rear ends of the rollers are connected to the upper and lower sides of the frame. The conveyor belt is internally meshed with the outer circumference of the rollers. The multiple buckets are fixedly connected to the outer circumference of the conveyor belt at equal intervals on one side.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] like Figure 1-3As shown, a screening device includes a base 1, a screening mechanism 4 is installed on the upper part of the base 1, and a conveying mechanism 5 is fixedly connected to one side of the base 1 by a bracket. The discharge port of the conveying mechanism 5 is located on the upper part of the screening mechanism 4.
[0020] In this embodiment, the conveying mechanism 5 includes a frame 501, two rollers 502, a conveyor belt 503, multiple buckets 504, and a geared motor 505. The frame 501 is mounted on one side of the upper part of the base 1 via a bracket. The front and rear ends of the rollers 502 are connected to the upper and lower sides of the frame 501. The conveyor belt 503 is internally meshed with the outer periphery of the rollers 502. The multiple buckets 504 are fixedly connected to the outer periphery of the conveyor belt 503 at equal intervals on one side. The geared motor 505 is mounted on one side of the upper part of the frame 501. The output end of the geared motor 505 passes through the side wall of the frame 501 and is fixedly connected to one end of the upper roller 502. Universal wheels 3 are provided at the four corners of the lower part of the base 1. Handles 2 are provided on the outer periphery of the upper part of the base 1. Rollers 506 are rotatably connected to the front and rear ends of the lower part of the frame 501.
[0021] Specifically, the drive geared motor 505 causes the connected shaft roller 502 to rotate, which in turn causes the conveyor belt 503 to rotate, thereby causing multiple buckets 504 to rotate. This allows the buckets 504 to scoop up sand from the bottom and discharge it from the outlet at the top of the frame 501. This eliminates the need for workers to scoop sand themselves, making the operation very labor-saving and convenient.
[0022] In this embodiment, the screening mechanism 4 includes a discharge hopper 401, a spring 402, a slag discharge port 403, a screening disc 404, and a vibrating motor. The lower end of the spring 402 is installed at the four corners of the upper part of the base 1, and the upper end of the spring 402 is installed on the lower part of the outer periphery of the discharge hopper 401. The lower part of the screening disc 404 is installed on the upper part of the discharge hopper 401 by a buckle. The slag discharge port 403 is opened on one side of the screening disc 404. The vibrating motor is installed on the lower part of the discharge hopper 401. The screening mechanism 4 also includes a connecting column 405, a dust cover 406, and a handrail 407. The lower part of the handrail 407 is fixedly connected to the upper part of the dust cover 406. One side of the dust cover 406 is rotatably connected to the upper end of the connecting column 405. The lower part of the connecting column 405 is fixedly connected to the upper part of the outer periphery of the discharge hopper 401. A feed inlet is opened on one side of the dust cover 406, and the feed inlet is aligned with the discharge port of the frame 501.
[0023] Specifically, the discharge hopper 401 is supported by the spring 402, which drives the vibration motor, causing the discharge hopper 401 to drive the screening disc 404 to vibrate, thereby screening the sand entering the screening disc 404. Sand that meets the particle size requirement passes through the screening disc 404 into the discharge hopper 401 and is finally discharged from the pipe at the bottom of the discharge hopper 401, while sand that does not meet the particle size requirement is discharged through the slag discharge port 403, thus continuously screening. The screening disc 404 with different screen holes can be replaced by a snap fastener.
[0024] Working principle:
[0025] A drive geared motor 505 rotates the connected roller 502, which in turn rotates the conveyor belt 503, causing multiple buckets 504 to rotate. This allows sand to be scooped up from below by the buckets 504 and discharged from the outlet at the top of the frame 501. This eliminates the need for workers to scoop sand themselves, making operation very labor-saving and convenient. A spring 402 supports the discharge hopper 401, driving a vibration motor to make the discharge hopper 401 vibrate the screening disc 404, thus screening the sand entering the screening disc 404. Sand that meets the particle size requirement passes through the screening disc 404 into the discharge hopper 401 and is finally discharged from the pipe at the bottom of the discharge hopper 401, while sand that does not meet the particle size requirement is discharged through the slag discharge port 403. This continuous screening process is achieved, and the screening disc 404 with different screen openings can be replaced by a snap fastener.
