[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figures 1 to 3 In the embodiment of the utility model, a construction engineering construction sand screening auxiliary tool includes a screen bracket 1, a pull rod 2, a baffle 3, a spring 4, a rotating seat 5, an eccentric wheel 6, a driving motor 7, a stand 8, a screw 9, a cushion block 10, a limit rod 11, a base 12, and a screen 13;

[0016] The base 12 is welded into a U shape by square steel profiles. The base 12 is horizontally arranged. The opening of the base 12 is used for the transport trolley to enter. A limit rod 11 is also arranged in the middle of the base 12. The two ends of the limit rod 11 are fixedly connected to the two sides of the base 12 to limit the wheels of the transport trolley. The base 12 is vertically connected to the stand 8, and the stand is a door-type bracket. Preferably, the stand 8 is arranged at one end away from the opening of the stand 8.

[0017] Two coplanar and parallel screen supports 1 are rotatably connected to the vertical frame 8 via a rotating shaft, and a screen 13 is fixedly connected between the two screen supports 1; the end of the screen support 1 that opens toward the base 12 is tilted upward and is rotatably connected to one end of the pull rod 2 via a pin shaft, and the other end of the pull rod 2 passes through a through hole opened on the rotating seat 5, and a baffle 3 is welded on the surface of the pull rod 2, and a spring 4 is arranged between the baffle 3 and the rotating seat 5, and the rotating seat 5 is also rotatably connected to the surface of the vertical frame 8 via an axis welded on its surface.

[0018] It should be noted that the axis of the pin connected to the pull rod 2 and the axis of the shaft welded on the surface of the rotating seat 5 are both set parallel to the plane where the base 12 is located, and the axis of the through hole opened on the rotating seat 5 and the axis of the pull rod 2 are both set perpendicular to the axis of the pin.

[0019] The downward surface of the screen support 1 contacts the outer surface of the eccentric wheel 6. The eccentric position of the eccentric wheel 6 is fixedly connected to the output shaft of the driving motor 7. The driving motor 7 is fixedly connected to the stand 8. The high-speed rotation of the driving motor 7 drives the eccentric wheel 6 to rotate eccentrically, thereby vibrating the screen support 1, and then vibrating the sand and gravel falling on the screen to promote separation.

[0020] The periphery of the base 12 is fixedly connected to four wheels for easy pushing on the site. At the same time, a through hole is opened on the square steel of the base 12 and a nut is welded. The nut is threadedly connected to the screw rod 9. The lower end of the screw rod 9 is connected to the pad 10 located below the base. When it is necessary to stop at the working position, the pad can be lowered by manually twisting the bolt to increase the friction with the ground, thereby improving the stability during use. Preferably, the other end of the screw rod 9 can be processed into a hexagonal prism to facilitate tool operation.

[0021] When the utility model is in use, a worker pushes a transport cart under the screen, and then manually controls the switch between the motor and the power supply to control the vibration, thereby realizing the separation of sand and gravel. Since the screen is arranged at an angle, it is conducive to the discharge of sand and gravel. By arranging a movable pull rod and spring energy storage, the vibration effect is stabilized. With this structure, it only takes one step to operate from screening sand to the device, thereby improving efficiency.

[0022] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
