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.

[0025] See also Figure 1-5 The utility model provides a technical solution: a vibrating sand and gravel separator, including a body 1, a discharge port 2, a screen 3, a fixing component, a guide funnel 4 and a vibration motor 5.

[0026] Preferably, a discharge port 2 is fixedly installed at one end of the body 1, a screen 3 is provided inside the body 1, and fixed components for installing or disassembling the screen 3 are provided between the two ends of the screen 3 and the inner walls on both sides of the body 1. A guide funnel 4 is fixedly installed at the corresponding position below the screen 3 and at the bottom of the body 1, and a vibration motor 5 is fixedly installed on one side of the guide funnel 4 and below one end of the body 1.

[0027] Preferably, the fixing assembly includes: a support plate 6 and a fixing mechanism 7, two groups of support plates 6 are provided, one side of the two groups of support plates 6 are respectively fixedly installed on the inner walls of the two ends of the body 1, six groups of fixing mechanisms 7 are provided between the two groups of support plates 6 and the two ends of the screen 3, and the two ends of the screen 3 are fixedly installed on the top of the two groups of support plates 6 through the six groups of fixing mechanisms 7.

[0028] Specifically, through the coordinated use of the support plates 6 and the fixing mechanisms 7, the screen 3 is first placed on the top of the two groups of support plates 6, and then the six groups of fixing mechanisms 7 are used to fix the two ends of the screen 3 to the two groups of support plates 6. Conversely, the screen 3 can be removed from the top of the two groups of support plates 6, thereby facilitating the installation or disassembly of the screen 3, and conveniently replacing the screen 3 with a screen 3 of different apertures after the screen 3 is disassembled, so that the device can screen sand and gravel more carefully, and realize different functions when screening sand and gravel, thereby improving the practicality of the device. At the same time, it is convenient to clean or maintain the disassembled screen 3, and avoid the screen 3 after long-term use, so that the residual concrete will not block the aperture of the screen 3 surface, thereby affecting the screening efficiency of the screen 3, and conveniently protecting the screen 3, thereby improving the service life of the screen 3.

[0029] Preferably, the fixing mechanism 7 includes: a mounting hole 701, a fixing rod 702, a fixing hole 703 and a limiting mechanism 704. The mounting hole 701 is opened through the top of the screen 3, and the interior of the mounting hole 701 is adapted to be provided with a fixing rod 702. The bottom end of the fixing rod 702 is slidingly connected to the inner cavity of the mounting hole 701. The fixing hole 703 is opened through the top of the support plate 6. The fixing hole 703 is corresponding to the mounting hole 701. The interior of the fixing hole 703 is adapted to the bottom end of the fixing rod 702, and the bottom end of the fixing rod 702 passes through the interior of the fixing hole 703 and extends to the bottom of the body 1 to connect with the limiting mechanism 704.

[0030] When the fixing holes 701 and 703 are respectively connected, the fixing holes 701 at the two ends of the top of the screen 3 are respectively matched with the fixing holes 703 at the top of the two groups of support plates 6. Then, the fixing rods 702 are inserted from the top of the mounting holes 701 and enter the mounting holes 701 and the fixing holes 703 in turn, so that the bottom ends of the fixing rods 702 are released from the bottom of the body 1. Then, the limiting mechanism 704 is used to limit and fix the bottom ends of the fixing rods 702, so that the fixing rods 702 cannot be pulled out from the inner cavities of the fixing holes 703 and the mounting holes 701, thereby fixing the screen 3 on the tops of the two groups of support plates 6. Conversely, the screen 3 can be removed from the tops of the two groups of support plates 6, thereby facilitating the fixing or removal of the screen 3. The operation is simple, convenient and fast.

One end of the telescopic spring 7044 is fixedly installed on the inner wall of one end of the limiting block 7041. The other end of the telescopic spring 7044 is fixedly connected to one side of the limiting plate 7043. The limiting hole 7045 is opened through one end of the fixed rod 702. The interior of the limiting hole 7045 is adapted to the surface of the limiting rod 7042, and one end of the limiting rod 7042 is inserted into the inner cavity of the limiting hole 7045.

[0032] When the locking cam 7043 is in the unlocked position, the locking cam 7043 is released and the locking cam 7043 is in the unlocked position.

[0033] Preferably, four groups of connecting plates 8 are evenly fixedly installed at both ends of the top of the screen 3, and three groups of blocking plates 9 are evenly fixedly installed between one side of each two groups of connecting plates 8. By using the connecting plates 8 and the blocking plates 9 in coordination, the sand and gravel mixture falling on the top of the screen 3 can be blocked and intercepted, so that the sand and gravel mixture can stay on the surface of the screen 3 for a longer time, thereby improving the effect of screening the sand and gravel mixture and increasing the efficiency of separating the sand and gravel mixture.

[0034] 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.
