Problems solved by technology

[0003] Buildings generally require mortar concrete for construction. The existing sand screening device generally uses a vibrating motor to drive the screen to vibrate to complete the sand screening. The vibration amplitude of the screen is small, and the movement of sand on the screen is small, which reduces the screening speed.

Embodiment 1

[0023] see Figure 1~2 , in the embodiment of the present invention, a kind of swing sand screening device for building, comprises cylinder 1, first screen 4 and second screen 2, and the bottom of described cylinder 1 is uniformly and symmetrically fixedly installed with support leg, and support leg Rollers 16 are installed at the bottom to facilitate the movement of the device. The top of the cylinder 1 is provided with a feed inlet 5, and a valve is installed on the feed inlet 5. A mounting shaft is installed on the center line of the cylinder 1. The cylinder 1 The first screen 4 and the second screen 2 are horizontally arranged on the upper and lower sides of the inner installation shaft respectively. The mesh of the first screen 4 is larger than the mesh of the second screen 2. A first discharge port 3 is provided under the screen 4 and the second screen 2 respectively, and the two first discharge ports 3 are respectively located on both sides of the cylinder 1. Valves are...

Embodiment 2

[0025] see image 3 The difference between this embodiment of the present invention and Embodiment 1 is that a two-way screw rod 22 runs through the installation shaft horizontally, the two-way screw rod 22 is rotationally connected with the installation shaft, and the threaded sections on both sides of the two-way screw rod 22 are threaded. There are internally threaded sleeves 21, the top and bottom of the internally threaded sleeves 21 are fixed with poles, both ends of the first screen 4 and the second screen 2 are equipped with brush sleeves 20, and the inner walls of the brush sleeves 20 are provided with The hairbrush in contact with the first screen cloth 4 and the second screen cloth 2 is fixedly connected with the brush cover 20 adjacent to the pole, and the two-way screw rod 22 is fixedly installed with a worm gear 23 on the rod end in the installation shaft. A worm 24 meshing with the worm wheel 23 is inserted on the installation shaft, and the other end of the wor...

Abstract

The invention discloses a swing sand screening device for buildings, and relates to the technical field of building equipment. The problems of low motion amplitude and low efficiency of a screen net in an existing sand screening device are solved. The swing sand screening device for the buildings comprises a cylinder body, a first screen net and a second screen net. A mounting shaft is rotatably installed on a center line of the cylinder body, the first screen net and the second screen net are separately and horizontally arranged on the upper side and the lower side of the mounting shaft in the cylinder body, and the mounting shaft is fixedly connected to the first screen net and the second screen net through a connecting rod. A driving mechanism for driving the forward and backward rotation of the mounting shaft is arranged on the end wall of the cylinder body, the driving mechanism includes a motor, a turntable, a connection rod, a first wedge block, a second wedge block, a rack anda gear, the mounting shaft, the first screen net, the second screen net and the driving mechanism are arranged, the driving mechanism drives the reciprocating motion of the first wedge block, finallythe second wedge block drives the reciprocating motion of the rack, the rack drives the forward and backward rotation of the mounting shaft through the gear, the mounting shaft drives the first screennet and the second screen net to swing back and forth around the mounting shaft through the connecting rod, and the screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a swing sand screening device for construction. Background technique [0002] Refers to the assets formed by man-made buildings, belonging to the category of fixed assets, including two categories: houses and structures. Housing refers to engineering buildings for people to live, work, study, produce, operate, entertain, store items and carry out other social activities. What is different from buildings are structures, which refer to engineering buildings other than houses, such as walls, roads, dams, wells, tunnels, water towers, bridges, and chimneys. [0003] Buildings generally require mortar concrete for construction. Existing sand screening devices generally use a vibrating motor to drive the screen to vibrate to complete sand screening. The vibration amplitude of the screen is small, and the movement of sand on the screen is small, which reduces the screeni...
