Description

Technical Field

[0001] This utility model relates to the technical field of construction sand and tailings extraction, specifically to a construction sand and tailings extraction device. Background Technology

[0002] Tailings refers to waste generated during ore processing. Since tailings contain certain mineral components and impurities that cannot be recycled, they can be preliminarily screened using appropriate extraction equipment to remove the impurities.

[0003] As disclosed in announcement number CN221694209U, a tailings sand screening device belongs to the field of tailings sand screening technology. It addresses the problem of filter layer clogging caused by large-scale dumping of sand and gravel during screening. The tailings sand screening device includes a screening mechanism comprising a screen cylinder assembly with a stirring component inside; and a cleaning mechanism including a moving component located inside the screen cylinder assembly. A cleaning component is installed on the bottom inner wall of the screen cylinder assembly. By starting a motor, the motor drives a stirring rod on a rotating rod, causing the stirring rod to rotate and stir the tailings sand. This prevents clogging of the filter holes on the filter plate during filtration. When it is necessary to clean the filtered impurities from the filter plate, a pull rod is manually pulled out to remove the filter plate and clean the impurities. This process avoids filter plate clogging and ensures filtration efficiency.

[0004] However, existing technologies have problems such as low efficiency in tailings screening and cumbersome operation in feeding useful components from tailings after removing impurities. For example, the comparative patents listed above have this problem.

[0005] To address these issues, we propose a construction tailings extraction device. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-7The present invention provides the following technical solution.

[0033] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a construction sand and tailings extraction device, comprising a support frame 1, a connecting frame 2, a screening box 3, and a screen 4. The connecting frame 2 is located at the upper end of the support frame 1, and the lower left end of the connecting frame 2 is hinged to the screening box 3. The bottom of the screening box 3 is fixedly connected to the screen 4. Figure 1 and Figure 2 As shown, the extracted sand tailings are added to the connecting frame 2 and the screening box 3, and the sand tailings are screened and extracted through the screen 4, thereby removing the impurities contained therein.

[0034] Example 2: To address the problem of low efficiency in tailings screening in existing technologies, this example provides a construction sand tailings extraction device. The device comprises a support block 5, a support plate 6, a motor 7, and a drive assembly 8. The upper left end of the support frame 1 is fixedly connected to the support plate 6, and the lower end of the support plate 6 is fixedly installed with the motor 7. An eccentric wheel 9 is fixedly connected to the output end of the motor 7. The support block 5 is fixedly connected to the front and rear ends of the connecting frame 2, forming a left-right sliding structure with the support frame 1. The drive assembly 8 is located on the left side of the support frame 1 and drives the connecting frame 2, screening box 3, and screen 4 to move left and right on the upper end of the support frame 1. The motor 7 drives the eccentric wheel 9 to rotate in the movable frame 10, and the eccentric wheel 9 is fitted against the inner wall of the movable frame 10. Movable rods 11 are fixedly connected to both the front and rear ends of the movable frame 10, and the right end of the movable rod 11 is fixedly connected to the connecting frame 2. The movable rod 11 forms a left-right sliding structure with the support frame 1. Figure 2 , Figure 3 and Figure 4 As shown, during the screening process, motor 7 can be started, and motor 7 drives eccentric wheel 9 to rotate in movable frame 10. Movable frame 10 drives movable rod 11 to slide at the upper left end of support frame 1, thereby causing connecting frame 2 to drive support block 5 to slide left and right at the upper end of support frame 1. Connecting frame 2, together with screening box 3 and screen 4, moves left and right at the upper end of support frame 1, so that tailings can be quickly screened and extracted through screen 4, thereby greatly improving the screening efficiency of tailings.

[0035] Example 3: To address the cumbersome process of feeding useful components from tailings after impurity removal in existing technologies, this example provides a construction sand tailings extraction device. The device includes a fixed column 12, a fixed plate 13, a connecting rod 14, a spring 15, and an auxiliary plate 16. The fixed column 12 is fixedly connected to the front and rear sides of the right end of the screening box 3, and is also engaged with the right end of the connecting frame 2. The fixed column 12 is also engaged with the middle of the fixed plate 13, and together with the fixed plate 13, it limits the movement between the screening box 3 and the connecting frame 2. The screening box 3 forms a flipping structure at the lower end of the connecting frame 2. The connecting rod 14 is fixedly connected to the side of the fixed plate 13, and a spring 15 is sleeved on the outer surface of the connecting rod 14. The connecting rod 14 and the auxiliary plate 16 form a sliding structure, and the auxiliary plate 16 is fixedly connected to the right end of the connecting frame 2. Figure 5 , Figure 6 and Figure 7 As shown, after all impurities are screened out, the power is turned off. Then, by pulling the fixed plate 13, the fixed plate 13 causes the connecting rod 14 to slide between the auxiliary plate 16. The connecting rod 14 compresses the spring 15, causing the spring 15 to undergo elastic deformation. The notch at the lower end of the fixed plate 13 is located below the fixed column 12, thereby releasing the restriction between the fixed column 12 and the connecting frame 2. The screening box 3 is flipped downwards, and the screening box 3 rotates at the lower end of the connecting frame 2. The screening box 3 causes the fixed column 12 to disengage from the connecting frame 2, forming a shape as shown. Figure 5 As shown in the diagram, the useful components extracted from the sieve box 3 are fed to the right, making the feeding operation very convenient.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
