Abstract

The invention discloses a coarse screening device for a sand screening machine, and belongs to the technical field of building equipment. The coarse screening device overcomes the defect that in the prior art, the sand screening efficiency is low due to the fact that sand is prone to adhesion and being huddled in the traditional sand screening way. The main structure of the coarse screening devicecomprises a machine frame and a feeding hopper, wherein the feeding hopper is arranged on the machine frame, a material leaking opening is formed in the lower portion of the feeding hopper, a feedingport in the feeding hopper is obliquely arranged, filter rollers which are arranged in parallel are arranged at the feeding port, and the filter rollers are welded to the feeding hopper; and a vibration motor is arranged on one side of the feeding hopper, and the vibration motor is connected to the right lower part of an outer shell of the feeding hopper. The coarse screening device is mainly used for coarse screening of sand.

Description

Technical field: [0001] The invention belongs to the technical field of construction equipment, and in particular relates to a coarse screening device for a sand screening machine. Background technique: [0002] In building construction, it is necessary to screen the sand to remove the stones and other debris from the sand to ensure the follow-up work. On the previous construction site, the traditional manual sand screening is usually used. The sand net is supported obliquely on the ground, and then the sand is manually poured on the top of the sand net. When the sand slides down the sand net, the sand smaller than the diameter of the gauze passes through the sand net, and the sand larger than the diameter of the sand net is filtered and slides down to the bottom of the sand net. At the bottom of the sand net, this method has low efficiency and high cost, which is far from meeting the requirements of construction for sand screening efficiency; and in the prior art, there is ...
