[0004] The current sand screening equipment is generally only equipped with a first-level sand screening device, which cannot meet different work needs, and during the work process, if too much sand is added at one time, the screen holes of the screen will be blocked, and the diameter of the screen is larger than the diameter of the screen. The sand has been spread on the screen, reducing the screening efficiency

Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0020] see Figure 1~4, in an embodiment of the present invention, a multi-stage screening device for intermittent feeding for construction, including a first screening box 1 and a second screening box 22, the first screening box 1 and the second screening box 22 have the same structure and are Round, with a sand bucket 4 above the first screening box 1, a first feed channel connected between the sand bucket 4 and the top of the first screening box 1, and a se...

Abstract
The invention discloses an intermittent discharge type multi-stage screening device for building. The device comprises a first screening box, a second screening box, a first sand screening device, a second sand screening device, a second motor, an incomplete gear, a first gear, a second gear, a third gear, a first rack, a first baffle and a second baffle. The first sand screening device comprisesa square frame, a screening net, a first spring, a first motor, a cam and a second spring. Since the first sand screening device and the second sand screening device are arranged, multi-stage sand screening can be carried out to meet different working requirements; since the second motor, the incomplete gear, the first gear, the second gear, the third gear, the first rack, the second gear, the first baffle and the second baffle are arranged, intermittent discharge is achieved by matching the components, the problem that net holes of a screening net are blocked since the one-time discharge amount is too high so as to affect the screening efficiency is avoided, sand on the screening net can be immediately discharged after each screening, and the screening efficiency is prevented from being affected.
Description
technical field [0001] The invention relates to the technical field of construction equipment, in particular to an intermittent feeding type multi-stage screening device for construction. Background technique [0002] Architecture is the general term for buildings and structures, and it is an artificial environment created by people using the material and technological means they have mastered, and using certain scientific laws, feng shui concepts, and aesthetic principles to meet the needs of social life. Building is a kind of space for people to live and use that people use soil, brick, tile, stone, wood; (reinforced concrete, profiles) and other building materials, such as residences, bridges, factories, gymnasiums, caves, water towers, Temples and more. Broadly speaking, landscape and gardens are also part of architecture. In a more general sense, the consciously constructed nests of animals can also be counted as buildings. [0003] Sand is an essential basic raw mat...
