Problems solved by technology

[0002] Sandstone refers to a loose mixture of sand grains and crushed stones. In geology, mineral or rock particles with a particle size of 0.074-2mm are called sand, and those with a particle size greater than 2mm are called gravel or breccia. If there are many gravels in the sandstone Gravel is called gravel; in daily life, some people also call sandstone sandstone. Sandstone needs to be screened before use. Sandstone with different particle sizes has inconsistent functions. Before mixing concrete in construction, in order to ensure the quality of concrete , It is necessary to clean the sand and gravel required for the preparation of concrete to remove the dust and soil existing in the surface and crevices of the sand and gravel. If these untreated sand and gravel are used, the strength of the concrete will be reduced and the concrete molding will be affected. Cleaning and screening The separation of the two parts leads to increased transportation costs, and in the prior art, most of the screening and cleaning are done manually, which greatly increases the cost, and the cleaning and screening are not thorough. For example, the prior art (202010903059.7) discloses a construction site sand and gravel cleaning screen The sub-device includes a body and a base. The base is symmetrically installed and fixed on the lower surface of the body. The body is provided with a feeding port for pouring sand and gravel. The body is equipped with a cleaning machine for cleaning the sand and gravel. A water tank is fixedly installed in the cleaning chamber, and a cleaning assembly is arranged above the water tank. The cleaning assembly includes a rotating roller and a plurality of cleaning boxes. One side of the cleaning box is provided with an opening for feeding materials. The rotating roller is rotatably installed in the cleaning chamber, and the cleaning box is fixedly installed on the rotating roller. The first water tank for water inflow and sewage discharge is equidistantly arranged on the cleaning box. One side of the cleaning box is hinged to match the opening. A hinged door, a cleaning plate is slidably installed in the cleaning box, and a second water tank matching the first water tank is set equidistantly on the cleaning board, and a cam is provided at one end of the cleaning plate
This technical solution realizes the cleaning of sand and gravel, but the function of the device is single, and additional cleaning is still required. Therefore, the present invention provides a sand and gravel cleaning and screening device for construction, which integrates cleaning and screening, and realizes multi-level cleaning at the same time and screening, easy to operate, high degree of automation, and reduce the workload of workers

Embodiment

[0021] Example: such as figure 1 The shown sand cleaning and screening device for construction includes a primary screening assembly 101 and a secondary screening assembly 102. The primary screening assembly 101 is used for preliminary screening and cleaning of sand and gravel, and the secondary screening assembly 102 is used for cleaning For further screening of sand and gravel, the secondary screening assembly 102 is equipped with sieve plates with different sizes of screen holes, and multiple sieve plates reciprocate to classify the sand and gravel. The conveying plate 108 is driven by a motor and installed on a fixed stand. The plate 117 is used to transfer the sand on the sand storage box 122 to the secondary screening assembly 102.

[0022] Such as figure 2 , image 3 , Figure 4 , Figure 5 The top of the shown primary screening assembly 101 is provided with a water pipe assembly 105, and the water pipe assembly 105 includes a double-head water pipe 106 and a singl...

Abstract

The invention discloses a building gravel cleaning and screening device which comprises a first-stage screening assembly and a second-stage screening assembly. The first-stage screening assembly comprises a water pipe assembly, a screening mechanism and a replacement assembly; the water pipe assembly conducts cleaning while gravel is screened; the screening assembly further comprises a reciprocating assembly to prevent gravel from blocking an inclined hole plate; and the replacement assembly automatically replaces a gravel-filled storage box and transports the gravel inside to the second-stage screening assembly. According to the device, the mechanism is simple, cleaning and screening work can be completed at the same time, meanwhile, the automation degree is high, and the screening precision is guaranteed through multi-stage screening.
