Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sand and gravel screening, in particular to construction sand and gravel screening equipment. Background Art
[0002] Construction buildings are spaces for people to live in and use, constructed with building materials such as earth, bricks, tiles, stones, wood, and in modern times, reinforced concrete and profiles, such as houses, bridges, factories, gymnasiums, cave dwellings, water towers and temples, etc. In a broad sense, landscape and gardens are also part of architecture. Sand and gravel refer to a loose mixture of sand and crushed stone. The structures of different sand and gravel vary greatly. Some have uniform particles, while others are of different sizes. Sand and gravel are often used on construction sites. Because the particle sizes of sand and gravel are uneven when they are purchased, and the particle sizes vary greatly, the sand and gravel must be screened through screening equipment.
[0003] In the prior art, the sand and gravel screening equipment used for construction is usually manually screened. The screen or screen plate is supported by pillars on the ground, and the construction sand and gravel are shoveled onto the screen or screen plate by tools such as shovels. The small construction sand and gravel are screened out by the gravity of the sand and gravel themselves. This screening method requires a lot of manpower. At the same time, it is difficult for the existing screening equipment to remove the filtered impurity sand and gravel during screening, which leads to blockage of the filter plate and screening problems.
[0004] To this end, we propose a construction sand and gravel screening equipment. Utility Model Content

[0010] Preferably, a fixed box is installed inside the screening box, a winding turntable is installed inside the fixed box, a first connecting rope and a second connecting rope are respectively installed inside the winding turntable, a rotating motor is installed on the surface of the back of the screening box located at the winding turntable, and the output end of the rotating motor passes through the inside of the screening box and is fixedly connected to the winding turntable.
[0011] Preferably, the bottom of the screening box is provided with protrusions, and a material receiving bucket is provided inside the screening box between the protrusions.
[0012] Preferably, a control panel is provided on the front end surface of the screening box, and the rotating motor is electrically controlled and connected by the control panel.
[0013] Compared with the prior art, the utility model has the following beneficial effects: through the cooperation of the filter plate and the winding turntable installed in the screening box, the rotating motor can be started when the filter plate completes screening of the sand and gravel, and the operation of the rotating motor drives the winding turntable to rotate, and the rotation of the winding turntable pulls the first connecting rope and the second connecting rope to wind, and the first connecting rope thereby drives the rotatably installed partition in the feed box to move downward, so that the two partitions of the chain are closed to seal the feed box to prevent other debris from entering, and at the same time the second connecting rope drives the fixed plate to move upward, and the upward movement of the fixed plate drives the filter plates symmetrically installed on both sides to fold and move upward, the filter plate moves to pull out the replacement plate, and the sand and gravel remaining on the filter plate can enter the recovery barrel through the discharge port and the guide plate opened in the replacement plate, thereby realizing the recovery of the residue and preventing the filter plate from being blocked due to excessive residual sand and gravel.
