Description

Technical Field

[0001] The utility model belongs to the field of construction engineering, and particularly relates to a fine sand screening device for construction engineering. Background Technique

[0002] In construction engineering, after the building body construction is completed, the indoor construction stage usually enters.

[0003] Since the sand particles accumulated indoors are of different sizes, in order to ensure the quality of the mortar and improve the bonding force during wall construction, it is necessary to screen out the fine sand for use during wall construction.

[0004] Since the sand screening equipment is large and cannot be carried indoors. When workers screen sand, they usually shovel the sand into an iron sieve and then manually shake the iron sieve to screen out the fine sand. Due to the large amount of fine sand used, it is time-consuming and laborious for workers to shovel and screen the sand, and the efficiency is low.

[0005] Therefore, we propose a fine sand screening device for construction engineering to solve the above problems. Content of the Utility Model

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] See also Figures 1 - 3 The utility model provides a technical solution for a fine sand screening device for construction engineering:

[0025] Embodiment 1:

[0026] according to Figures 1 - 3 As shown, it comprises an annular track 1, a screening basin 4 and a driving assembly. A plurality of supporting legs 5 are installed on the annular track 1, and an extension seat 2 is integrally connected to the side thereof.

[0027] The top of the screening basin 4 is open, and a plurality of screening holes 41 for screening fine sand are evenly arranged on the bottom.

[0028] An annular edge plate 61 is mounted on the outer side of the screening basin 4 , and the annular edge plate 61 is slidably arranged in the annular track 1 . The screening basin 4 is supported and restricted by the annular edge plate 61 to ensure the stability of the screening basin 4 during rotation.

[0029] A plurality of universal balls 62 are installed on the upper and lower surfaces of the annular edge plate 61. The upper and lower sets of universal balls 62 are in contact with the inner top and inner bottom of the annular track 1 respectively. By providing the universal balls 62, the friction is reduced so that the screening basin 4 can rotate in the annular track 1.

[0030] The driving assembly includes a driving motor 31 and a large pulley 34 mounted on the outside of the screening basin 4. The driving motor 31 is installed on the top of the extension seat 2, and its output shaft passes through the extension seat 2 and is mounted with a small pulley 32. The small pulley 32 and the large pulley 34 are connected by a transmission belt 33. By starting the driving motor 31, the driving motor 31 drives the rotation of the small pulley 32, and the transmission belt 33 drives the large pulley 34, thereby driving the screening basin 4 to rotate around the annular track 1. Under the action of centrifugal force, the sand is distributed in the screening basin 4, and the fine sand is quickly screened out through the sieve holes 41, so that the workers do not need to manually shake the screening basin 4, thereby reducing the labor of the workers and improving the screening efficiency of the fine sand. In addition, the device has a simple structure and a small size, which is convenient for workers to carry indoors for use.

[0031] During actual use, for a fine sand screening device for construction engineering of the present utility model, first, workers carry the device to the sand screening location, then hold an iron shovel to shovel the sand into the screening basin 4, and finally start the driving motor 31. The driving motor 31 drives the rotation of the small pulley 32, and the transmission belt 33 drives the large pulley 34, thereby driving the screening basin 4 to rotate around the annular track 1. Under the action of centrifugal force, the sand is distributed in the screening basin 4, and the fine sand is quickly screened out through the sieve holes 41.

The bottom discharge port of the hopper 71 corresponds to the inner cavity of the screening basin 4. By setting the hopper 71, workers shovel the sand into the hopper 71. The hopper 71 can temporarily store the sand, and at the same time, enable a small amount of sand to fall into the screening basin 4 through the bottom discharge port, thereby controlling the amount of sand in the screening basin 4 and improving the screening effect.

[0034] The connecting rod 72 is welded to the bottom of the hopper 71. During use, the bottom end of the connecting rod 72 is inserted into the corresponding support foot 5, and the hopper 71 is installed above the screening basin 4. When not in use, the connecting rod 72 can be pulled out from the support foot 5, enabling the hopper 71 and the screening basin 4 to be carried separately.
