Problems solved by technology
[0003] In order to solve the above problems, the present invention provides a paving grab bucket for tunnel, bridge and road construction with screening function, which can solve the problem that the existing grab buckets do not have the function of screening or multi-stage screening. Small particles such as sand inside the flap are easy to adhere to its inner wall. If it is not removed by the vacuum device in time, it will not only shorten the service life of the grab bucket but also affect the health of nearby workers.

The invention relates to a paving grab bucket having the function of sieving, for tunnel bridge road construction. The paving grab bucket comprises electric telescopic rods, a first grab flap, a second grab flap and a mounting seat, wherein the electric telescopic rods are hinged to two sides of the bottom end of the mounting seat; a support column is mounted at the central position of the mounting seat, and a first support arm and a second support arm are separately hinged to the bottom of the support column; and the first grab flap is hinged to one end away from the support column, of the first support arm, and the second grab arm is hinged to one end away from the support arm, of the second support arm. A driving motor, a stirrer and two screen meshes of which the hole diameters are different are mounted in the grab flap, so that the grab flap can sort raw materials for construction of tunnel bridge roads, with different particle diameters in a two-class sieving sorting manner for use, manual sieving is not needed, the paving grab bucket is convenient, and the working efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of grabs, in particular to a paving grab with screening function for tunnel, bridge and road construction. Background technique [0002] The grab bucket is a bucket that can be opened and closed for grabbing sediment, gravel and various bulk goods. With the rapid development, there are more and more places where tunnel, bridge and road construction needs to be carried out. Raw materials of various particle sizes are needed in the construction of tunnels, bridges and roads, and the raw materials for tunnel, bridge and road construction are transported into the transport vehicle. Grab is a tool that must be used, and materials of various particle sizes need to be classified and screened for use. Existing grabs do not have the function of screening or multi-stage screening. Small particles such as sand are easy to adhere to its inner wall. If it is not removed in time through the vacuum device, it will not onl...
