Description
Technical Field
The invention relates to the technical field of equipment for constructional engineering, in particular to sandstone screening equipment for constructional engineering.
Background
Sand, which refers to a loose mixture of sand and gravel. Geology refers to mineral or rock particles with the particle size of 0.074-2 mm as sand, gravel or cobbles with the particle size of more than 2mm as gravel, and sand gravel if most of crushed stones in the sand are gravel. In daily life, sandstone is also called as sandstone, and screening is to use a sieve to enable fine-grained materials smaller than a sieve pore in materials to penetrate through a sieve surface, and coarse-grained materials larger than the sieve pore to be retained on the sieve surface, so that the process of separating coarse materials from fine materials is completed. The separation process can be regarded as consisting of two stages, material stratification and fine grain screening. The material layering is the condition for completing the separation, and the fine particles are suitable for screening for the purpose of separation.
The existing sandstone screening equipment for constructional engineering, such as patent No. CN109513606A, has the advantages that a motor is used as a driving source, a crank slide block and an extrusion spring are used as transmission mechanisms, reciprocating motion between screening mechanisms is driven, and the screening function can be realized. The device has the advantages of compact and simple structure, easy operation, low cost and the like, and can realize the screening of gravels with different sizes by adjusting the shape and the size of the hole body of the screening frame.
Based on the searched content, the following problems are found by combining the devices in the prior art; the supporting force of the top screening box is nearly not available in the using process of the equipment, the weight of gravels to be screened by the device is large, the quantity of the gravels is extremely large, the equipment can be directly damaged and cannot be used once the gravel exceeds the bearing range of the device, the equipment is assisted by more workers during general work, once the accident happens, the life safety of peripheral workers can be directly threatened, irreparable loss can be caused, the use is extremely unfavorable for people, troubles are brought to people, in addition, in the screening process of the reciprocating motion of the top screening mechanism, the collecting bin at the bottom can be dynamically switched between exposure and covering, stones in the screening mechanism at the top can easily and accidentally enter the collecting bin exposed at the bottom, in addition, when the screening mechanism at the top moves to the extreme edge of one side, i.e. part of the screen body protruding above the collecting bin falls directly to the ground, only a reduction in the size of the screen or a reduction in the reciprocating stroke of the screen can be adopted, but this solution limits the screening efficiency.
