Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically a sand screening device for building construction. Background Technology
[0002] Sand is indispensable in construction projects, and sand is divided into coarse sand, fine sand, gravel sand, etc. The sorting of sand is generally carried out by sand screening equipment.
[0003] Currently, in traditional construction, sand is typically screened manually. This involves manually feeding the sand to an inclined screen mesh for sieving. However, the sand is often scattered and requires manual collection, which is labor-intensive, time-consuming, and delays the project. Furthermore, if the sand is very wet, the screen mesh can easily become clogged, requiring manual clearing, which is time-consuming, inefficient, and fails to meet construction requirements. To address these issues, the inventor proposes a sand screening device for construction to solve these problems. Utility Model Content
[0004] In order to solve the problems of high labor intensity, low efficiency and clogging of screen holes by wet sand in current sand screening operations, the purpose of this utility model is to provide a sand screening device for construction.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a sand screening device for construction, comprising a horizontal plate, with legs fixedly connected to both ends of the horizontal plate, a sand screening frame disposed above the horizontal plate, an extension frame fixedly connected to the output end of the sand screening frame, a storage box placed at the output end of the extension frame, springs disposed at the four corners of the bottom surface of the sand screening frame, a vibrating motor disposed in the middle of the bottom surface of the sand screening frame, a protective cover disposed above the vibrating motor, a storage tank disposed diagonally above the sand screening frame, a discharge pipe fixedly connected to the middle of the bottom surface of the storage tank, a sand guide plate disposed below the discharge pipe, the output end of the sand guide plate extending into the sand screening frame, a heating plate disposed on the bottom surface of the sand screening frame, and the sand screening frame being made of a heat-conducting material.
[0006] Preferably, the vibrating motor has a vibrating frame on its side wall, and a connecting column is fixedly connected to the side wall of the vibrating frame. The end of the connecting column away from the vibrating frame is fixedly connected to the bottom surface of the sand screening frame. The input end of the heating plate is electrically connected to a power supply connector, which is connected to an external power supply to power the heating plate and heat the sand screening frame to prevent the wet sand from clogging the screen holes. When the vibrating motor is started, the sand screening frame vibrates under the action of the vibrating frame and the spring. The sand screening frame is placed at an incline, and the vibrating sand screening frame can screen the sand. Fine sand can fall to the bottom through the screen holes of the sand screening frame, and stones can fall into the storage box through the inclined sand screening frame for centralized processing.
[0007] Preferably, the protective cover has an isosceles triangle cross-section, is wider at the bottom than at the top, and is located below the sand screening frame. The protective cover is used to shield and protect the vibrating motor to prevent fine sand from falling into the vibrating motor during sand screening. The inner bottom wall of the sand screening frame is provided with screen holes, and the sand screening frame is placed at an angle. During sand screening, fine sand in the sand can fall through the screen holes of the sand screening frame to separate the fine sand from the stones.
[0008] Preferably, a first fixing block is fixedly connected to the top end of the spring, and a second fixing block is fixedly connected to the bottom end of the spring. The top surface of the first fixing block is fixedly connected to the bottom surface of the sand screening frame, and the bottom surface of the second fixing block is fixedly connected to the top surface of the horizontal plate. The spring is fixedly connected to the sand screening frame via the first fixing block and to the horizontal plate via the second fixing block. A vertical frame is provided on one side of the sand screening frame, and a fixing frame is provided on the side wall of the storage tank. The side wall of the fixing frame is connected to the vertical frame. The side wall of the sand guide plate is fixedly connected to a fixing plate. The side of the fixing plate away from the sand guide plate is fixedly connected to the side wall of the upright. The storage tank is used to hold the sand to be screened. The sand falls to the sand guide plate through the discharge pipe and can then flow into the sand screening frame for sand screening. The sand guide plate is placed at an angle, and there is a gap between the bottom surface of the sand guide plate and the top surface of the sand screening frame to avoid the sand guide plate affecting the vibration of the sand screening frame.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] 1. This utility model facilitates sand screening operations, effectively reduces labor intensity, and improves work efficiency. The sand in the storage tank can be discharged into the screening frame through the sand guide plate. With the help of the vibrating motor and vibrating frame, and the spring, the screening frame can vibrate. During the sand screening operation, the fine sand in the sand can fall through the screen holes of the screening frame, and the stones can fall into the storage box through the inclined screening frame for centralized processing.
[0011] 2. This utility model has good applicability. When encountering damp sand, it can prevent the damp sand from clogging the screen holes. By connecting the power supply connector to an external power supply device, the heating plate is powered to heat the sand screening frame, so that the sand at the screen holes is in a dry state, so that it can pass through the screen holes smoothly and avoid clogging the screen holes.
