Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] As described in the background art, in the specific application process of this patent, it can only separate sand and stones, and cannot automatically collect and process the separated stones, which requires manual cleaning, thereby increasing the labor intensity of workers and reducing the practicability of the overall device.

[0030] To solve this technical problem, the present utility model provides a new sand screening device, which is applied to construction engineering.

[0031] Specifically, please refer to Figure 1 , a new sand screening device specifically includes a base 1, elastic mechanisms 4 are arranged at the positions of the four end corners at the upper end of the base 1, a sand screening mechanism 3 is arranged at the position between the four elastic mechanisms 4 at the upper end of the base 1, and a loading mechanism 2 is arranged at the middle position of the upper end of the base 1.

[0032] For the new sand screening device provided by the present utility model, through the structural design of the sand screening mechanism 3, when screening sand, the sand and stones can be separated through the design of the sand screening mechanism 3. After the stones and sand are separated, the separated stones and sand can be classified and conveyed through the design of the sand screening mechanism 3. The conveyed stones can be collected and processed by the loading mechanism 2, thereby improving the practicability of the overall device.

[0033] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] Embodiment 1:

[0035] Please refer to Figures 1 - 5 , a new type of sand screening device, which includes a base 1. Elastic mechanisms 4 are provided at the positions of the four end corners at the upper end of the base 1. A sand screening mechanism 3 is provided at the position between the four elastic mechanisms 4 on the upper end of the base 1. A bearing mechanism 2 is provided at the middle position of the upper end of the base 1.

[0036] Through the above structural design, it can be seen that the elastic mechanism 4 can be supported by the base 1, the sand can be screened by the sand screening mechanism 3 to separate the sand from the stones, the sand screening mechanism 3 can be supported by the elastic mechanism 4, and at the same time, the screening speed of the sand screening mechanism 3 can be adjusted through the cooperation of the sand screening mechanism 3 and the elastic mechanism 4. The bearing mechanism 2 can collect and process the stones screened by the sand screening mechanism 3.

[0037] Specifically, the sand screening mechanism 3 includes a housing 5. Connecting blocks 7 are fixedly connected to both sides of the outer sides of the two ends at the lower end of the housing 5 and corresponding to the elastic mechanisms 4. A window is opened on one side of the housing 5. A first round rod 6 is fixedly connected to one end of the window. A sealing door 8 is rotatably connected to the side of the first round rod 6 away from the housing 5. The sealing door 8 is sealingly connected to the window.

[0038] Furthermore, filling ports 9 are fixedly connected to both ends of the upper end of the housing 5. The filling ports 9 are communicated with the housing 5. A vibration motor 10 is fixedly connected to the position between the two filling ports 9 at the upper end of the housing 5. A screening assembly 11 is arranged inside the housing 5.

[0039] Through the above structural design, it can be seen that when it is necessary to clean the screening assembly 11 inside the housing 5, the sealing door 8 can be rotated and opened with the center of the first round rod 6 as the axis, so that the sealing of the window by the sealing door 8 is separated. After separation, the screening assembly 11 inside the housing 5 can be cleaned.

[0040] Specifically, the screening assembly 11 includes a downward sliding cylinder 12 and a downward sliding plate 14. The downward sliding cylinder 12 is located at the middle position inside the housing 5. The upper end of the downward sliding cylinder 12 is fixedly connected to the top inside the housing 5. Slots 15 are opened on both sides of the downward sliding cylinder 12. Sieve meshes 13 are fixedly connected to the positions of the two slots 15. One end of the sieve mesh 13 away from the slot 15 is fixedly connected to the inner wall of the housing 5. The sieve mesh 13 is inclined. The number of the downward sliding plates 14 is two. The two downward sliding plates 14 are respectively located at the lower ends of the two sieve meshes 13. One end of the downward sliding plate 14 is fixedly connected to one side inside the housing 5. The downward sliding plate 14 is inclined.

[0041] Specifically, the carrier mechanism 2 includes a collection box 20, the collection box 20 corresponds to the lower end of the sliding cylinder 12, both sides of the lower end of the collection box 20 are fixedly connected with sliders 22, and chutes are provided at positions on the upper end of the base 1 corresponding to the sliders 22, and the sliders 22 are slidably connected with the chutes. The middle of one end of the collection box 20 is fixedly connected with a handle 21.

[0042] Through the above structural design, it can be seen that when it is necessary to screen sand, the sand can be poured from the upper ends of the two filling ports 9, and then the sand slides into the sieve 13 inside the housing 5 through the filling ports 9. Due to the inclined setting of the sieve 13, after the sand slides onto the sieve 13, it can slide down to the position of the sliding cylinder 12 through the inclination of the sieve 13. Then, when the sand slides towards the sliding cylinder 12, the sand can fall onto the lower sliding plate 14 through the sieve 13. Furthermore, due to the inclination of the lower sliding plate 14, when the sand falls onto the lower sliding plate 14, the sand can be made to slide downward. The trolley can be pushed below the lower sliding plate 14 to collect the sand. At the same time, the stones in the sand will slide towards the inside of the notch 15 through the sieve 13, so that the stones fall into the sliding cylinder 12 through the notch 15, and then the stones fall into the interior of the collection box 20 through the sliding cylinder 12, and the collection box 20 is used to collect the stones. When it is necessary to process the stones inside the collection box 20, the collection box 20 can be pulled out through the handle 21 to process the stones inside the collection box 20.

[0043] Embodiment 2:

[0044] A new type of sand screening device provided in Embodiment 1 is further optimized. Specifically, as Figure 2 、 Figure 3 、 Figure 6 shown, the elastic mechanism 4 includes a fixed column 16, the lower end of the fixed column 16 is fixedly connected with the base 1, the end of the fixed column 16 away from the base 1 is fixedly connected with a second round rod 17, the end of the second round rod 17 away from the fixed column 16 passes through the connecting block 7 and extends to the outside of the upper end of the connecting block 7 and is fixedly connected with a limiting block 18. A spring 19 is fixedly connected to the lower end of the connecting block 7 and on the outside of the second round rod 17, and the end of the spring 19 away from the connecting block 7 is fixedly connected with the fixed column 16.

[0045] Through the above structural design, it can be seen that when it is necessary to accelerate the sand screening of the sand, the vibration motor 10 at the upper end of the housing 5 can be started. Then, after the vibration motor 10 is started, the vibration motor 10 drives the housing 5 to shake. When the housing 5 slides, the housing 5 can squeeze the connecting block 7. Then, when the connecting block 7 is squeezed, the connecting block 7 can squeeze the spring 19. Then, when the connecting block 7 is pressed down to a certain extent, the force of the squeeze can be released by the spring 19 to push the connecting block 7 to move upward and reset. The up and down movement of the connecting block 7 can drive the housing 5 to jolt, and then the jolting of the housing 5 can accelerate the sand screening work.
