[0002] A sand screening machine is a kind of sand mining machine that uses screening equipment to separate coarse and fine materials. When using a sand screening machine, after placing sand and gravel on the screen, the screen is vibrated to screen the coarse and fine materials in the sand and gravel. Therefore, it can be seen that the existing sand screening machines basically meet people's practical needs, but the following problems still exist.

[0003] When the construction is almost completed and the building needs to be repaired to a certain extent, concrete may be needed. When the operator is mixing the concrete, the sand and gravel may need to be separated. In the process of separating the sand and gravel, a sand and gravel machine may be used. However, due to the small amount of concrete required, the operator may use a smaller sand screening machine to screen the sand. However, during the transportation process, the screening machine may be composed of a motor and metal parts, which may cause the sand screening machine to be heavy, making it inconvenient for the operator to carry. For this reason, we propose a construction sand screening machine. Utility Model Content

[0020] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] Example:

[0022] See also Figure 1 - Figure 5A construction sand screening machine comprises a column 1, a screening slot 2 is arranged above the column 1, and a screen 3 is threadedly installed in the middle of the screening slot 2, a limiting block 16 is welded around the screening slot 2, and the ends of the limiting block 16 are all abutted with a first spring 8, the ends of the first spring 8 are all abutted with a fixing seat 9, and a mounting block 10 is welded at the end of the fixing seat 9, and the surface of the mounting block 10 is sleeved with a slot 12 opened on the column 1, and the fixing seat 9 and the column 1 are both sleeved with a collar 11 on one side where the fixing seat 9 and the column 1 are attached to each other, and the collar 11 and the column 1 are mutually engaged. The two ends of the screening tank 2 are welded with mounting brackets 7, and a motor 5 is arranged in the middle of the mounting bracket 7. The surface of the motor 5 is sleeved with a motor housing 4 threadedly mounted on the mounting bracket 7. After the motor 5 passes through the middle of the mounting bracket 7, a polarizing block 6 is welded at the end of the motor 5. When the operator installs the column 1 and the screening tank 2, the fixing seat 9 is first pulled to move the fixing seat 9 left and right. When the fixing seat 9 moves, the fixing seat 9 pulls the first spring 8 to bend the first spring 8, and then the fixing seat 9 drives the mounting block 10 to connect with the plug. The slots 12 are aligned with each other. When the mounting block 10 and the slot 12 are aligned with each other, the fixing seat 9 is released. After the fixing seat 9 no longer applies pressure to the first spring 8, the first spring 8 elastically recovers, and the first spring 8 pushes the fixing seat 9 to move, so that the fixing seat 9 drives the mounting block 10 to move. The fixing seat 9 drives the mounting block 10 to move, and the mounting block 10 is inserted into the slot 12. The mounting block 10 is inserted into the slot 12, which facilitates the fixing seat 9 to be installed on the column 1, thereby installing the first spring 8 and the screening slot 2. On the column 1, when the sand screening machine is in use, it is convenient to install the column 1 and the screening trough 2, and by pulling the fixing seat 9, the fixing seat 9 drives the first spring 8 to bend, and the fixing seat 9 drives the mounting block 10 to move out of the slot 12, and the fixing seat 9 is separated from the column 1, so that the column 1 and the screening trough 2 are separated from each other. When the column 1 and the screening trough 2 are separated from each other, the operator can carry the column 1 and the screening trough 2 separately, reducing the weight of the entire sand screening machine and improving the convenience of the operator in carrying the sand screening machine.

[0023] In other embodiments, a receiving groove 13 is welded at the end of the column 1, and a limiting block 16 is inserted in the middle of the receiving groove 13, and the limiting block 16 is snap-connected to the receiving groove 13. Through the screening groove 2, the first spring 8 is driven to move by the limiting block 16, and the first spring 8 drives the mounting block 10 to move through the fixed seat 9, so that the fixed seat 9 and the mounting block 10 are aligned with the receiving groove 13 and push the screening groove 2. The screening groove 2 drives the first spring 8 to move through the limiting block 16, and the first spring 8 drives the fixed seat 9 to be inserted into the receiving groove 13. When the fixed seat 9, the mounting block 10 and the first spring 8 are inserted into the receiving groove 13, the limiting block 16 is inserted into the opening of the receiving groove 13, and the limiting block 16 is snap-connected to the receiving groove 13. The snap-connection between the receiving groove 13 and the limiting block 16 makes it easy to weld the limiting block 16 in the receiving groove 13, thereby folding the sand screening machine and improving the operator's carrying of the sand screening machine.

[0024] In other embodiments, a slider 20 is welded to one side of the collar 11 and the column 1, and a slide groove 15 provided in the column 1 is sleeved on the surface of the slider 20, and a second spring 14 provided in the slide groove 15 abuts against the inner wall of the slide groove 15 and the surface of the slider 20. When the column 1 and the screening tank 2 are installed, the collar 11 is pulled first to make the collar 11 drive the slider 20 to move, and the slider 20 slides in the slide groove 15. When the slider 20 slides in the slide groove 15, the slider 20 squeezes the second spring 14, causing the second spring 14 to undergo elastic deformation, and the collar 11 is used to move the slider 20 in the column. 1, the collar 11 opens the slot 12. After the collar 11 opens the slot 12, the fixing seat 9 then drives the mounting block 10 to be inserted into the slot 12, and the fixing seat 9 is installed on the column 1. After the fixing seat 9 is installed on the column 1, the collar 11 is released, and the collar 11 is no longer pressed against the second spring 14 by the slider 20. The second spring 14 elastically recovers, and the second spring 14 pushes the collar 11 to move through the slider 20, so that the collar 11 moves to the side where the fixing seat 9 and the column 1 are in contact with each other. The collar 11 limits the slot 12 to prevent the mounting block 10 from moving out of the slot 12.

[0025] In other embodiments, the mounting blocks 10 are all configured to be "L"-shaped, and the slots 12 are all configured to be "L"-shaped grooves. The "L"-shaped grooves provided in the slots 12 match the "L"-shaped grooves provided in the mounting blocks 10. When the "L"-shaped groove provided in the mounting blocks 10 is inserted into the "L"-shaped groove provided in the slots 12, the "L"-shaped grooves provided in the slots 12 facilitate accommodating the "L"-shaped grooves provided in the slots 12. Furthermore, after the "L"-shaped grooves provided in the mounting blocks 10 are inserted into the "L"-shaped grooves provided in the slots 12, the mounting blocks 10 can only move left and right, thereby facilitating limiting the moving direction of the mounting blocks 10 when inserted into the slots 12.

[0026] In other embodiments, the collar 11 is provided with a "C"-shaped groove. The "C"-shaped groove provided by the collar 11 matches the rectangular blocks provided by the fixed seat 9 and the column 1. By the mutual matching of the "C"-shaped groove provided by the collar 11 and the rectangular blocks provided by the fixed seat 9 and the column 1, the "C"-shaped groove provided by the collar 11 can be sleeved on the surfaces of the rectangular blocks provided by the fixed seat 9 and the column 1, improving the stable sleeving of the "C"-shaped groove provided by the collar 11 on the surfaces of the column 1 and the fixed seat 9.

[0027] In other embodiments, spring grooves 19 are symmetrically opened at both end parts on both sides of the limiting block 16. A button 18 and a third spring 17 are respectively arranged inside the spring grooves 19. Both end parts of the third spring 17 are respectively abutted between the inner wall of the spring groove 19 and the surface of the button 18. The ends of the button 18 all penetrate through the receiving groove 13. When the operator needs to insert the limiting block 16 into the receiving groove 13, the operator first presses the button 18. After the button 18 is subjected to pressure, the button 18 moves in the spring groove 19, and the button 18 squeezes the third spring 17, causing the third spring 17 to undergo elastic deformation. After the third spring 17 undergoes elastic deformation, the third spring 17 gives way to the button 18, and the button 18 enters the spring groove 19, causing the button 18 to give way to the receiving groove 13. Subsequently, after the spring groove 19 is inserted into the receiving groove 13, the limiting block 16 drives the button 18 to move to the front end of the circular through hole opened on the surface of the receiving groove 13 through the spring groove 19. After the inner wall of the receiving groove 13 no longer presses against the button 18, the elastic deformation of the third spring 17 is restored, and the third spring 17 pushes the button 18 to move, causing the button 18 to be inserted into the circular through hole opened on the surface of the receiving groove 13, thereby fixing the limiting block 16 in the receiving groove 13 and facilitating the mutual connection of the limiting block 16 and the receiving groove 13.

[0028] In other embodiments, circular through holes are opened on one side of the receiving groove 13 away from the column 1. The circular through holes opened on one side of the receiving groove 13 away from the column 1 match the cylinders provided by the button 18. By the mutual matching of the circular through holes opened on one side of the receiving groove 13 away from the column 1 and the cylinders provided by the button 18, the cylinders provided by the button 18 can be inserted into the circular through holes opened on one side of the receiving groove 13 away from the column 1. And after the cylinders provided by the button 18 are inserted into the circular through holes opened on one side of the receiving groove 13 away from the column 1, the surfaces of the cylinders provided by the button 18 are mutually attached to the inner walls of the circular through holes opened on one side of the receiving groove 13 away from the column 1, facilitating the stable movement of the button 18 in the circular through holes opened on one side of the receiving groove 13 away from the column 1.
