specific Embodiment approach 1

[0029] Specific implementation mode one: as Figure 1-Figure 10 As shown, this embodiment describes a sand screening device for construction equipment, including a split feeding device 1, a crushing device 2, a grinding device 3, and a sand screening cylinder 4; the split feeding device 1 includes a storage tank 1-1, Support cylinder 1-3, rotating cylinder 1-4, filter plate 1-6, rotating block 1-7, motor I 1-8, support plate 1-9; the upper end of the support cylinder 1-3 is fixedly connected with a storage cylinder 1-1; the bottom of the storage tank 1-1 is provided with a discharge port I1-2, and the discharge port I1-2 is connected to the support tube 1-3; the support plate 1-9 is fixedly connected to the support tube 1-3 inside; the motor I1-8 is fixedly connected to the upper end of the support plate 1-9, the output shaft of the motor I1-8 is fixedly connected to the rotating block 1-7; the top of the rotating block 1-7 is set as a slope, And fixedly connected with rotati...

specific Embodiment approach 2

[0034] Specific implementation mode two: as Figure 4 As shown, this embodiment is a further description of Embodiment 1. The pitch of the spiral plate 2-3 gradually decreases from top to bottom, and the depth of the spiral leaves of the spiral plate 2-3 gradually decreases from top to bottom. small. It is convenient to make the large pieces of sand be pressed down in the process of continuous downward movement, thereby facilitating the follow-up operation of the grinding device 3 .

specific Embodiment approach 3

[0035] Specific implementation mode three: as Figure 5 As shown, this embodiment is a further description of Embodiment 1. The minimum distance between the grinding block 3-3 and the top end of the inner wall of the grinding cylinder 3-1 is greater than the distance between the grinding block 3-3 and the bottom end of the inner wall of the grinding cylinder 3-1. The minimum distance, that is, the gap between the grinding block 3-3 and the top of the grinding cylinder 3-1 is smaller than the gap at the bottom, so that the fine sand is continuously ground by the friction force during the continuous downward movement of the sand block, and finally all pass through the grinding cylinder 3-1 Bottom filter hole enters the upper end of screen mesh II 4-7-3.

Abstract

A sand screening device and a sand screening method for construction equipment belong to the field of construction material screening. The side of the housing is provided with a material inlet II and a shaft hole; the motor III is fixedly connected to the outside of the housing through a bracket, and the output shaft of the motor III is fixedly connected to the shaft on the sand screening device; the movable plate I and movable plate II The lower ends are connected to the shell through hinges, and the movable plate I and movable plate II are located on a set of opposite surfaces on the shell; the bottom end of the shell is provided with a discharge port III; the support rod is fixedly connected to the inside of the shell On the ground; the sand inlet is located below the material inlet II. The invention can not only increase the area of ​​the screen mesh in the equipment shell with limited space, and then achieve the effect of increasing the efficiency of sand screening, but also break the sand blocks through the grinding device and the crushing device, so that waste materials can be used and materials can be saved; The advantages of simple operation and saving manpower.

Description

technical field [0001] The invention relates to a sand screening device and a sand screening method for construction equipment, belonging to the field of construction material screening. Background technique [0002] In the currently commonly used sand screening devices and equipment, due to the limitation of the size of the equipment, the size of the screen is fixed, resulting in low sand screening efficiency, and the sand cannot be broken, wasting materials. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the size of the screen in the sand screening equipment is limited by the shell, resulting in low efficiency of sand screening, failure to break sand blocks, complicated operation and waste of manpower during the sand screening operation, and to provide a construction equipment Use sand screening device and sand screening method. [0004] The present invention realizes above-mentioned object, and the technical scheme ...
