Embodiment 1

[0024] see Figure 1~3 , in the embodiment of the present invention, an adjustable building sand screening device includes a base 1 and a screening frame installed on the base 1, a sieve plate 4 is arranged in the screening frame, and the sieve plate 4 is driven by a vibrating screening mechanism 5; The vibration screening mechanism 5 includes a rotating disk 51, a movable rod 52, a sliding member 56 and a transmission rod 54 for transmission and connection of the sieve plate 4, wherein the rotating disk 51 is installed on the mounting seat 53 fixed on the base 1, and installed A power device (not shown) for driving the rotating disk 51 is installed on the seat 53, and the rotating disk 51 is provided with a strip groove 511, and the movable rod 52 is arranged on the front end surface of the rotating disk 51, and the movable rod 52 slides It is connected to the screening frame and can move back and forth along the vertical direction. A waist-shaped hole 521 arranged along its ...

Embodiment 2

[0028] see figure 1 , 3 -5, the embodiment of the present invention is optimized on the basis of embodiment 1, mainly for the screening box, specifically:

[0029] In this embodiment, the screening frame includes an outer frame body 2 and an elastic unit plate 3 arranged at openings on both sides of the outer frame body 2, and the elastic unit plate 3 includes a first plate body 31 and a second plate body 32, wherein The first plate body 31 is a hollow structure, the second plate body 32 is slidably inserted in the first plate body 31, and the end of the second plate body 32 far away from the first plate body 31 is fixed with a symmetrically arranged connecting ear 33, both sides A connecting spring 34 is connected between the lower end surface of each connecting ear 33 and the bottom of the inner cavity of the first plate body 31, and the connecting spring 34 is sleeved on the periphery of the second plate body 32, so that the elastic unit plate 3 can produce elasticity con...

Embodiment 3

[0035] see figure 1 , in this embodiment, also includes loading frame 7, and described loading frame 7 is embedded on the support 6 that is fixed on base 1, and the bottom of loading frame 7 is provided with feeding opening 71, and loading opening 71 is facing filter box.

[0036]Further, an intermittent blanking mechanism is also installed on the bracket 6, and the intermittent blanking mechanism includes a blanking motor 81 and a rotating plate 82, wherein the blanking motor 81 is installed on the bracket 6, and the rotating plate 82 is fixed on On the shaft extension end of the blanking motor 81, the rotating plate 82 is provided with a perforation 83 matching the size of the blanking opening 71, so that when the perforation 83 overlaps with the blanking opening 71, the blanking opening 71 will be opened , the sand and gravel can fall from the loading frame 7, and when the perforation 83 and the feeding opening 71 are staggered, the feeding opening 71 will be closed, so th...

Abstract

The present invention disclosed a adjustable building sand and gravel screening device, including the base and the screening box installed on the base, and the screenboard driven by the vibration screening mechanism.In the transmission rod of the transmission connecting sieve, the turning plate is installed on the installation seat fixed to the base. The active rod is opened with a waist -shaped hole in the length direction.The tight nut, one of the ends of the column body is sliding a sliding card in the strip slot, and the other end sliding card is located in the waist -shaped hole.The invention vibration screening mechanism composed of components such as rotating discs, activity rods, slider, and transmission rods can change the upper and lower movement range of the movement rod by adjusting the position of the rotor rod by adjusting the position of the rotor rod when using it, so as to complete the completionThe adjustment of the amplitude allows the overall device to flexibly adjust according to actual needs.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an adjustable building sand screening device. Background technique [0002] Sand and gravel is a common raw material in the field of construction. It has a variety of particle sizes. In order to meet different use requirements, sand and gravel need to be screened after entering the construction site to achieve the classification of sand and gravel. [0003] At present, most screening devices for sand and gravel use vibration to realize the screening action, but the amplitude of most existing screening devices is not adjustable, so that they cannot be flexibly adjusted according to different usage requirements, and there are certain defects in use. Contents of the invention [0004] The purpose of the present invention is to provide an adjustable construction sand screening device to solve the above problems. [0005] To achieve the above object, the present invention provi...
