Problems solved by technology

[0003] When screening sand, it is often necessary to use a sand screening device. When the current sand screening device is in use, because the position of the discharge port is fixed, the sand will accumulate at one point, affecting the screening efficiency. The existing sand and soil screening device for road and bridge construction is not easy to swing and transport the sand and clean the screen, resulting in low screening efficiency and residual sand on the screen

Embodiment 1

[0040] see figure 1 and figure 2 , the present invention provides a kind of sand and soil screening device for road and bridge construction through improvement, comprising fixed mount 1, spring 2, discharge nozzle 11, vibrating motor 14, second discharge bucket 15, reciprocating pusher 12 and cleaning mechanism 13, The fixed frame 1 is elastically connected to the four corners of the bottom of the screening frame 3 through the spring 2, and the spring 2 is fixedly connected to the bottom of the screening frame 3. The right end of the screening frame 3 is provided with a control panel 4, and the front end of the control panel 4 is equipped with a button 5. The reciprocating pusher 12 is connected with the The front end of the discharge nozzle 11 is fixedly connected, the cleaning mechanism 13 is fixed to the front end of the top of the screening frame 3, the left end of the screening frame 3 is fixed with a power lead 6, the inside of the screening frame 3 is fixed with a scre...

Embodiment 2

[0049] The present invention provides a sand screening device for road and bridge construction through improvement. The first motor 1222 and the left end of the cam 1223 move eccentrically, which is beneficial to make the cam 1223 push the push rod 1224. The inner side of the receiving block 1232 is arranged There are movable beads 12321, and the movable beads 12321 are fixedly connected with the bottom of the push rod 1224, which is beneficial to make the push rod 1224 move smoothly.

[0050] The present invention provides a sand screening device for road and bridge construction through improvement, and its working principle is as follows;

[0051] First, before use, the sand and soil screening device for road and bridge construction is placed horizontally, so that the fixed frame 1 and the support frame 9 are fixedly supported by the device;

[0052] Second, when in use, connect the external power supply through the power lead 6 to provide power to the device, then place the...

Abstract

The invention discloses a sandy soil screening device for road and bridge construction. The sandy soil screening device for road and bridge construction comprises a reciprocating pushing device and acleaning mechanism; a pushing mechanism is arranged in a protective frame, and a first motor drives a cam to do eccentric motion, so that a push rod is enabled to move in a reciprocating manner to push a swinging frame to swing, and the advantage of quickly driving a swinging mechanism to link is achieved; the swinging mechanism is arranged at the bottom of a discharge nozzle, and when the push rod moves in a reciprocating manner, the swinging frame can be driven to swing around a positioning shaft, so that the swinging frame is enabled to slide at the upper end of a sliding shaft through a sliding chute, the swinging frame can swing stably, and the advantages of preventing sand from being conveyed and concentrated on one point and increasing the screening efficiency are achieved; and thecleaning mechanism is arranged at the top of the screening frame, and a second motor drives a pinion to rotate, so that a bull wheel drives a driving handle to swing around a fixed disc through a movable handle, the driving handle drives a brush plate to brush the upper end of a screen, and the advantage of preventing the sand on the screen from remaining is achieved.

Description

technical field [0001] The invention relates to the related fields of road and bridge construction, in particular to a sand and soil screening device for road and bridge construction. Background technique [0002] Road bridges are generally composed of several parts such as roadbed, road surface, bridge, tunnel engineering and traffic engineering facilities. The traffic load transmitted by the road surface is an important part of the entire highway structure. The roadbed mainly includes several parts such as the subgrade body, side slope, side ditch and other auxiliary facilities. [0003] When screening sand, it is often necessary to use a sand screening device. When the current sand screening device is in use, because the position of the discharge port is fixed, the sand will accumulate at one point, affecting the screening efficiency. The existing sand and soil screening device for road and bridge construction is not easy to swing and transport the sand and clean the scr...
