Description

Technical Field

[0001] The utility model relates to the field of sand screening equipment, in particular to water conservancy engineering raw material screening equipment with a weighing function. Background Art

[0002] Sand has stable chemical properties and a hard texture, which is strong enough to resist weathering. It is very suitable for construction, water conservancy project construction, etc. The coarseness of sand refers to the average coarseness of sand particles of different particle sizes mixed together, usually divided into coarse sand and fine sand. The particle grading of sand refers to the matching ratio of sand particle size. The raw sand will be screened for impurities with the help of screening equipment before use, but the existing screening equipment does not have a weighing function. It relies on two situations for weighing. One is to calculate the weight by the feeding device before screening, but this calculation method is not only slow but also time-consuming. The second is to rely on manpower to weigh after screening, but manual weighing is too cumbersome. Therefore, a water conservancy project raw material screening equipment with a weighing function is proposed. Utility Model Content

[0026] Example 2

[0027] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 6 The flip plate 64 is curved, and one end of the flip plate 64 away from the fixed rod 63 contacts the inner wall of the screening shell 1. The flip plate 64 will squeeze the sand and move it outward during the rotation process, so that not only can the debris be discharged from the debris discharge port 3, but also the sand accumulation during movement can be prevented from affecting the screening effect. The rotating rod 62 is in the shape of a rectangular parallelepiped, and a matching groove is provided inside the fixed rod 63. The output motor 61 can be detached through the cover plate 5. During the rotation process, it is only necessary to insert the rotating rod 62 into the groove to drive the flip plate 64 to rotate.

[0028] During use of the utility model, the user first blocks the debris discharge port 3 by blocking the blocking plate 9, and then the user adds sand into the screening shell 1. As the sand is added, the screening shell 1 moves downward, pressing the sliding rod to move. The movement of the sliding rod not only pulls the tension spring 74, but also drives the sealing plate 73 to squeeze the hydraulic fluid 77, so that most of the hydraulic fluid 77 flows from the first flow groove 76 into the second flow groove 75. Then the user checks the rising distance of the hydraulic fluid 77 through the observation window and the weight calculation value, so that the weight of the sand can be known. When the appropriate weight is reached, the user covers the top of the screening shell 1 with the cover plate 5, and inserts the rotating rod 62 into the interior of the fixed rod 63 during the covering process. After covering, the user starts the output motor 61, and the rotation of the output motor 61 drives the rotating rod 62 to rotate, and the rotation of the rotating rod 62 drives the fixed rod 63 to rotate, and the fixed rod 63 drives the flip plate 64 to flip the sand, so that the sand falls from the screening net 2 to the sand discharge port 4 after screening, and the user can collect it at this time.

[0029] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
