Description

Technical Field

[0001] This utility model relates to the field of construction equipment, and more particularly to a sand screening device for construction. Background Technology

[0002] Sand is an important raw material in construction sites, used to make concrete and other building materials. However, most sand cannot be used directly and needs to be screened to remove larger stones and impurities, leaving fine sand to make concrete and other construction materials.

[0003] Existing sand screening methods involve placing sand into a sieve plate and then shaking the plate to filter out fine sand, leaving larger stones and impurities on the plate. Some current equipment has sieve plates that are laid flat and cannot be tilted, making it difficult to remove large stones and impurities. Other sieve plates are tilted, which makes it easier to separate and remove large stones and impurities, but some fine sand also falls into the waste pile of large stones and impurities, often requiring secondary screening and wasting time. Therefore, this solution provides a sand screening device for construction. Utility Model Content

[0004] The purpose of this utility model is to provide a time-saving and labor-saving sand screening equipment for building construction.

[0005] This utility model is achieved through the following measures: A sand screening device for construction is characterized by comprising a base frame, wherein a plurality of springs I are provided at one end of the base frame, a bracket I is provided on the plurality of springs I, a screen plate is hinged to the bracket I, a plurality of springs II are provided at the other end of the base frame, a bracket II is provided on the plurality of springs II, the other end of the screen plate away from the bracket I is provided on the bracket II, and a vibration motor is provided on the bracket II.

[0006] The specific features of this utility model also include: The upper side of the second support is provided with a long groove, and the lower side of the other end of the sieve plate is provided with a long plate that cooperates with the long groove. After the sieve plate is rotated, the long plate can be inserted into the long groove or can be removed from the long groove. Obviously, the width of the long groove is greater than the width of the long plate.

[0007] The outer surface of the second support has a threaded screw that extends into a long groove. A handle is located at the outer end of the screw, and a groove is provided on the long plate to engage with the screw. When the handle is rotated to screw the screw into the long groove along the threaded structure, the inner end of the screw extends into the groove, limiting the long plate's movement away from the groove and keeping the screen plate in the sand-screening position. Reverse rotation of the handle disengages the inner end of the screw from the groove, allowing the long plate to rotate and disengage from the groove. Both sides of the groove have rounded corners to facilitate the inner end of the screw entering the groove. When the vibration motor is started, the second support causes the screen plate to vibrate, thus achieving sand screening.

[0008] The upper side of the sieve plate is surrounded by a surrounding plate. The surrounding plate near the hinge of the sieve plate is set as an inclined plate. When the sieve plate is tilted, it is convenient for large stones and impurities to roll off the sieve plate.

[0009] Vertical rods are provided on both sides of the base frame near the support one. Each of the two vertical rods has a pulley one at its top. Ropes are provided on the side panels of the sieve plate near the support two. Each of the free ends of the ropes one has a pulley two. Ropes two are fixedly installed on both vertical rods. The free ends of the ropes two pass sequentially around the corresponding pulleys two and one and then onto a horizontal tie rod. That is, the free ends of the ropes two on both sides are fixed to the horizontal tie rod. After the original sand on the sieve plate has been sieved for a sufficient time, manually pulling down the horizontal tie rod tilts the sieve plate upwards, causing large stones and impurities to roll off the sieve plate and slide to the outside. Since a sufficiently long sieving time can be selected, the sieved large stones and impurities contain less fine sand, eliminating the need for secondary sieving. The fine sand falls below the sieve plate after passing through it. The pulleys achieve a labor-saving effect.

[0010] The lower part of the base frame is provided with several support legs.

[0011] The slot has rounded corners on both sides to facilitate the insertion of the lead screw.

[0012] The base frame has sand drop holes in the middle that cooperate with the sieve plate.

[0013] The beneficial effects of this utility model are as follows: This solution uses a hinged screen plate and a manual operation of a horizontal pull rod to tilt the screen plate, thereby successfully removing large stones and impurities from the screen plate. This solves the problem of inconvenient cleaning of large stones when the screen plate is laid flat. At the same time, it takes advantage of the fact that the screen plate can be screened for a sufficient amount of time when it is laid flat, avoiding the problem of needing a second operation when the screen plate is simply tilted.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0023] See Figures 1-4 A sand screening device for construction includes a base frame 1. A plurality of springs 15 are provided on one end of the base frame 1. A support 14 is provided on the plurality of springs 15. A screen plate 2 is hinged on the support 14. A plurality of springs 23 are provided on the other end of the base frame 1. A support 24 is provided on the plurality of springs 23. The other end of the screen plate 2 away from the support 14 is provided on the support 24. A vibrating motor 6 is provided on the support 24.

[0024] The support 2 4 has a long groove 18 on its upper side, and the other end of the screen plate 2 has a long plate 17 that cooperates with the long groove 18 on its lower side. After the screen plate 2 rotates, the long plate 17 can be inserted into the long groove 18 or can be removed from the long groove 18. Obviously, the width of the long groove 18 is greater than the width of the long plate 17.

[0025] The outer surface of the second bracket 4 is threaded with a lead screw that extends into the long groove 18. A handle 5 is attached to the outer end of the lead screw, and a groove 16, which mates with the lead screw, is provided on the long plate 17. When the handle 5 is rotated to screw the lead screw into the long groove 18 along the threaded structure, the inner end of the lead screw extends into the groove 16, limiting the long plate 17 in the direction of disengagement from the long groove 18, thus keeping the screen plate 2 in the sand-screening position. Reverse rotation of the handle 5 causes the inner end of the lead screw to exit the groove 16, allowing the long plate 17 to rotate with the screen plate 2 and disengage from the long groove 18. Both sides of the groove 16 are rounded to facilitate the inner end of the lead screw entering the groove 16. When the vibration motor 6 is started, the second bracket 4 drives the screen plate 2 to vibrate, thereby achieving sand screening.

[0026] The upper side of the sieve plate 2 is provided with a surrounding plate 7. The surrounding plate 7 near the hinge of the sieve plate 2 is set as an inclined plate. After the sieve plate 2 is tilted, it is convenient for large stones and impurities to roll off the sieve plate 2.

[0027] Vertical rods 11 are installed on both sides of the base frame 1 near the support 14. Pulleys 12 are installed at the top of both vertical rods 11. Ropes 8 are installed on the side panels 7 of the sieve plate 2 near the support 4. Pulleys 9 are installed at the free ends of both ropes 8. Ropes 10 are fixedly installed on both vertical rods 11. The free ends of ropes 10 pass through the corresponding side pulleys 9 and 12 and are connected to a horizontal tie rod 13. Both ends are fixed to the horizontal tie rod 13. After the original sand on the screen plate has been screened for a sufficient time, the horizontal tie rod 13 is pulled down manually, which can tilt the screen plate 2 upward, thereby causing large stones and impurities to roll off the screen plate 2 and slide to the outside of the screen plate 2. Since a sufficiently long screening time can be selected according to the situation, there is less fine sand in the screened large stones and impurities, so there is no need for secondary screening. The fine sand falls below the screen plate 2 after passing through the screen plate 2. The pulley setting achieves the function of saving labor.

[0028] The lower part of the base frame 1 is equipped with several support legs.

[0029] Both sides of the slot 16 are rounded to facilitate the insertion of the lead screw.

[0030] The base frame 1 has sand drop holes in the middle that cooperate with the sieve plate 2.

[0031] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
