Sand screening machine capable of preventing filter screen from being blocked for building construction

Abstract

The invention relates to the technical field of sand screening equipment, in particular to a sand screening machine capable of preventing a filter screen from being blocked for building construction.The sand screening machine capable of preventing the filter screen from being blocked for building construction has the advantages that a first rotating shaft is driven to rotate based on a servo motor, a second rotating shaft is driven to rotate through gear transmission, on one hand, coarse sand enters a crushing cavity from a feeding hopper, crushing is carried out under the action of a crushing cutter; on the other hand, the second rotating shaft further drives a fourth rotating shaft to rotate through a coupler, a crank throw rotates along with the fourth rotating shaft, a first connecting rod and a second connecting rod drive the filter screen to shake left and right, the filtering efficiency is improved, the filter screen is prevented from being blocked; the fact that a filter pipeis detachably connected with the shell is adopted in conjunction with the coupler connection mode of the fourth rotating shaft and the second rotating shaft, so that the filter pipe is integrally detached conveniently, the coarse sand is conveniently removed; and the second rotating shaft is used for driving a first cylindrical cam to rotate, a first supporting rod drives a baffle plate to move upand down, the baffle plate periodically enters and exits a feeding pipe, blocking or communicating for feeding are carried out, and intermittent feeding is achieved.

Description

technical field [0001] The invention relates to the technical field of sand screening equipment, in particular to a sand screening machine for building construction that can prevent filter screens from clogging. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. [0003] Building construction can be roughly divided into basic engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc. The place where the construction works is called "construction site" or "construction site", also called construction site. [0004] Building construction is a production process that people use various building materials and mechanical equipment to build ...

Problems solved by technology

Obviously, this method corresponds to a large amount of artificial physical exertion, and the efficiency is also low.

Therefore, there have been many sand sieving machines, but when in use, the sand sieving machine can only sieve the fine sand from the net, and the coarse sand will often block the filter screen, affecting the screening effect of the filter screen, and even making the sieve Sand operations cannot be carried out, slowing down the progress of the project
