[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] See also Figure 1-Figure 4 The utility model provides a technical solution: a sand screening machine for construction engineering, including a support tube 1, the outer sides of both ends of the support tube 1 are movably sleeved with support bearings 3, the outer sides of the support bearings 3 are sleeved with support rings 2, the outer sides of the support rings 2 are fixedly installed with two rotating columns 4, the outer sides of the two rotating columns 4 are movably sleeved with frames 5, the bottom of the frame 5 is fixedly installed with a manual hydraulic telescopic rod 6, the bottom of the manual hydraulic telescopic rod 6 is fixedly installed with a support 7, the outer sides of the fixed part and the telescopic end of the manual hydraulic telescopic rod 6 are fixedly installed with reinforcement rods 15, and the bottom of the support 7 is fixedly installed with a Two supporting legs 17, two telescopic plates 8 are fixedly mounted on the opposite sides of the support 7, and a number of adjustment holes 14 are provided on the inner sides of the two telescopic plates 8. The internal movable adjustment holes 14 are plugged with adjusting bolts 18. The inner wall of the support tube 1 is fixedly mounted with a spiral auger plate 16, and the inner side of the spiral auger plate 16 is fixedly mounted with a filter screen cartridge 9. One end of the support tube 1 is fixedly mounted with a driven gear ring 10, and the outer side of the driven gear ring 10 is engaged with a driving gear 11. One side of the driving gear 11 is connected to a reduction motor 12, and the outer side of the reduction motor 12 is fixedly mounted with a mounting ring 13.
[0020] The working principle of the above technical solution is as follows: when in use, the operator adjusts the height of the manual hydraulic telescopic rod 6 and inserts the adjusting bolt 18 into the adjusting hole 14 to adjust the inclination of the support cylinder 1. Then, the sand and gravel are put into the interior of the filter screen cylinder 9 through one end of the filter screen cylinder 9, and the reduction motor 12 is started. The reduction motor 12 rotates to drive the driving gear 11 to rotate, and the driving gear 11 drives the meshing driven gear ring 10 to rotate, thereby prompting the support cylinder 1 to rotate, and then drives the spiral auger plate 16 and the filter screen cylinder 9 to rotate synchronously, thereby driving the sand and gravel to roll and screen inside the filter screen cylinder 9, and the smaller gravel after screening passes through the filter screen cylinder 9 It enters the opposite side of the support cylinder 1 and the filter screen cylinder 9, and the sand and gravel are delayed in falling under the spiral rolling action of the spiral auger plate 16, so that the sand and gravel are screened under the filtering action of the filter screen cylinder 9. When cleaning the sand and gravel, the operator flushes the sand and gravel inside the filter screen cylinder 9 through a water pipe. Due to the rotation delay of the spiral auger plate 16, the sand and gravel are discharged, thereby increasing the cleaning time of the sand and gravel. Finally, the sand and gravel are collected through the extended diversion of the filter screen cylinder 9, and the sand and gravel are collected through the diversion of the support cylinder 1, thereby completing the screening and cooperating with the cleaning, improving the efficiency of the operation, thereby reducing the working intensity of the operators, and the overall structure is simple and easy to maintain.
[0021] In another embodiment, Figure 1-Figure 4 As shown, the two ends of the reinforcement rod 15 away from the manual hydraulic telescopic rod 6 are fixedly mounted on the outside of the support 7 and the frame 5 respectively, and the positions of the two telescopic plates 8 correspond to the positions of the support legs 17.
[0022] The reinforcement rod 15 reinforces the fixed part and the telescopic end of the manual hydraulic telescopic rod 6, thereby stabilizing the fixed connection between the structure and the reinforcement rod 15 and the support 7, and increasing the supporting strength of the structure. The corresponding positions of the telescopic plate 8 and the support leg 17 facilitate increasing the structural strength, reducing torque deflection, and stabilizing the force.
[0023] In another embodiment, Figure 1-Figure 4 As shown, the adjustment holes 14 are linearly and evenly distributed inside the telescopic plate 8 .
[0024] This solution adjusts the spacing of the supports 7 through the telescopic plate 8, which is convenient for cooperating with the height adjustment of the manual hydraulic telescopic rod 6. The adjustment holes 14 with fixed spacing sizes are convenient for cooperating with the specific tilt angle adjustment. The adjusting bolts 18 are inserted through the adjustment holes 14 to fix the length of the telescopic plate 8, thereby adjusting and fixing the structure, facilitating the height adjustment of the manual hydraulic telescopic rod 6, and indirectly adjusting the tilt angle of the support tube 1, thereby prompting the support tube 1 to change the tilt angle under the active support of the rotating column 4 and the frame 5, and the overall adjustment and fixation are convenient.
[0025] In another embodiment, Figure 1-Figure 4As shown, the spiral auger plates 16 are spirally distributed evenly on the opposite sides of the support cylinder 1 and the filter screen cylinder 9, and the gap size between the support cylinder 1 and the filter screen cylinder 9 ranges from 5 to 15 cm.
[0026] The function of the spiral auger plate 16 is to limit the sand and gravel flowing on the opposite sides of the support cylinder 1 and the filter screen cylinder 9, so as to delay the discharge time of the sand and gravel and increase the flushing time, thereby stabilizing the use effect of the structure and facilitating coordinated flushing. The gap size between the support cylinder 1 and the filter screen cylinder 9 determines the adaptation to different filtering and screening efficiencies and sand and gravel flow rates. Too large or too small will affect the pumping and flushing effect.
[0027] In another embodiment, Figure 1-Figure 4 As shown, the mounting ring 13 is fixedly mounted on the outside of the support ring 2 , and the support ring 2 and the support bearing 3 are symmetrically and evenly distributed at both ends of the support tube 1 .
[0028] The mounting ring 13 fixes the reduction motor 12 in a specific position, so that it can drive the structure to rotate after being fixed. The symmetrical arrangement of the support ring 2 and the support bearing 3 facilitates the stable support of the structures at both ends and the relative stability of the structure.
[0029] In another embodiment, Figure 1-Figure 4 As shown, the length of the filter screen cylinder 9 is larger than that of the support cylinder 1 , and the length of the filter screen cylinder 9 extending out of the support cylinder 1 is more than 15CM.
[0030] The filter screen cylinder 9 extends the length of the branch cylinder 1, which is convenient for separating the sand and gravel after screening to avoid mutual influence, and is convenient for inputting screening materials, thereby stabilizing the effect after screening, facilitating collection, and reducing the relative stability effect.
[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
