Double-pipe type broken stone grain screening device for road patching

Abstract

The invention provides a double-pipe gravel screening device for road filling, which includes a protective barrel, a bottom support frame, an upper support frame, clamping claws, and a screening barrel; the bottom support frame is vertically rotated upwards and connected to the protective barrel Inside; the upper support frame is vertically connected with the lifting device, and the screening motors are fixed vertically downward on both sides of the bottom end; the number of clamping claws is two, which are respectively installed on both sides of the bottom of the upper support frame, including connecting rods, The supporting plate, the sliding plate, the clamping rod, the supporting rod and the clamping block; the number of screening buckets is also two, which are respectively installed on both sides of the upper end of the bottom support frame, including the bucket body and the bucket cover. The invention adopts the combination of the centrifugal rotation of the screening bucket itself and the rotation of the support frame on the top to screen the crushed stones, which ensures the screening quality while increasing the screening volume; at the same time, the screening efficiency is high, which effectively saves screening time and filling costs; the structure is novel , easy to manufacture and suitable for popularization and use.

Description

technical field [0001] The invention belongs to the field of road construction equipment, and in particular relates to a double-pipe gravel screening device for road filling. Background technique [0002] With the development of social economy, in order to facilitate traffic and transportation, more and more highways are laid and the scope is wider and wider. In order to reduce costs and man-hours, the existing expressways can be reconstructed on the existing lines when laying, but the road surface of the existing lines is uneven and needs to be filled again. In order to save costs and ensure the filling quality, crushed Stones are filled. However, the crushed stones are of different sizes, so they need to be screened first, which is cumbersome and time-consuming. [0003] Therefore, in order to solve the above problems, it is a difficult problem urgently needed by those skilled in the art to develop a device capable of quickly screening gravel particles.
