Embodiment Construction

[0013] like figure 1 As shown, the external silo dredging machine of the present invention includes a hydraulic cylinder 1 and a dredging rake, the hydraulic cylinder 1 is vertically arranged outside the silo (not shown in the figure), the dredge rake is vertically arranged inside the silo, and the hydraulic cylinder The piston rod 3 of 1 is connected with the dredging rake through a driver.

[0014] The dredging rake includes a vertically arranged push-pull rod 4, and the push-pull rod 4 is axially and horizontally provided with several scrapers 5. The limit device 6 (the limit device is an existing mature technology, and the specific structure will not be described in detail), the limit device 6 plays a role in limiting the left and right swing of the push-pull rod 4, and provides a slideway for the push-pull rod 4 to move up and down; The fixed bracket 7 on the feed bin and the lever 2 hinged on the fixed bracket 7, one end of the lever 2 is hinged with the upper end of th...

Abstract

The invention discloses an external dredging machine for a bin, which comprises a hydraulic cylinder and a dredging harrow, wherein the hydraulic cylinder is vertically arranged outside the bin, the dredging harrow is vertically arranged inside the bin, and a piston rod of the hydraulic cylinder is in driving connection with the dredging harrow by a driver. The hydraulic cylinder is arranged outside the bin, so that the external dredging machine not only is better in work environment condition, and but also is easy to maintain, overhaul and change. The driver adopts the principle of a lever, so that the dredging harrow is easy to move up and down for dredging.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, in particular to an external bin dredging machine. Background technique [0002] In my country's electric power, coal, chemical industry, metallurgy, building materials and other industries, the silos containing materials are generally square cones and cones with a large upper part and a smaller lower part. Many materials are relatively viscous and easy to block the silos. The dredging rake is generally installed in the warehouse, and the dredging rake is powered by a hydraulic cylinder, and the hydraulic cylinder is connected to the power station (including the oil supply station and the control box) through two high-pressure oil pipes. The existing hydraulic cylinder is fixed on the inner wall of the silo, and the dredging rake is vertically slid on the inner wall of the silo through the limiting device, and the hydraulic cylinder directly drives the dredging rake to reciprocate up and ...
