Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a continuous sand screening device. Background Art

[0002] Sand screening refers to the process of removing impurities from sand through certain means and equipment to make it purer and finer. Sand screening is a very common task in daily life, commonly seen in the fields of construction, landscaping, agricultural planting, etc. It can not only improve work efficiency, but also ensure work quality, making the final work effect more beautiful and practical.

[0003] Currently, construction sites generally use manual sand screening, that is, workers shovel sand and pour it onto a mesh for screening. There are generally problems such as low sand screening efficiency and inability to screen sand in multiple layers, resulting in the inability to differentiate sand into multiple levels.

DETAILED DESCRIPTION

[0020] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0021] As shown in the figure, a continuous sand screening device includes a sand screening bucket 1. Sand inlet funnels 13 are provided around the top of the sand screening bucket 1. A triangular bracket is fixedly connected to the bottom of the sand screening bucket 1, and a guide funnel 14 is fixedly connected to the bottom of the sand screening bucket 1. A guide rail is provided below the guide funnel 14, and a transport vehicle 15 is slidably connected to the guide rail. A sealing door 16 is rotatably connected to the sand screening bucket 1 on one side of the rotating ring 10.

[0022] A sand screening structure is provided in the sand screening bucket 1, and the sand screening structure includes a motor 2, a guide rod 3, a fixed rod 4, a screen 5, a rotating groove 6, a connecting ring 7, a clamping block 8 and a clamping groove 9. The motor 2 is connected to the top of the sand screening bucket 1, the guide rod 3 is driven by the motor 2, the fixed rod 4 is connected to the guide rod 3, the clamping block 8 is connected to the outer sides of both ends of the fixed rod 4, the clamping block 8 is truncated, the clamping groove 9 is provided on the outer surface of the clamping block 8, the rotating groove 6 is provided in the center of the screen 5, the connecting ring 7 is connected to the rotating groove 6, and the inner side of the connecting ring 7 is clamped with the clamping groove 9. A rotating ring 10 is fixedly connected to the outer side of the screen 5, a positioning groove 11 is provided on the inner wall of the sand screening bucket 1, and the rotating ring 10 is located in the positioning groove 11.

[0023] Working principle: Sand enters the sand screening bucket 1 from the sand inlet hopper 13, and the motor 2 drives the guide rod 3 and the fixed rod 4 to rotate. The clamping blocks 8 at both ends of the fixed rod 4 rotate, and the screen 5 clamped in the clamping blocks 8 rotates to perform synchronous screening. Sand from the sand inlet hopper 13 is screened by two layers of screens 5 and then falls into the guide funnel 14, and finally slides into the transport vehicle 15 to be transported away. The coarse sand is taken out and recycled after the sealing door 16 is opened.

[0024] In summary, the guide rod 3 and the fixed rod 4 are driven to rotate by the motor 2, which drives the clamping block 8 to rotate, thereby driving the screen 5 clamped in the clamping block 8 to rotate for screening.
