Description

Technical Field

[0001] The utility model relates to the technical field of garden greening projects, in particular to a small sand and gravel separation device for garden greening project construction. Background Art

[0002] At present, small sand and gravel separation devices are related to the fields of garden greening engineering, construction equipment technology and mechanical technology. In the construction of garden greening projects, the mixing of impurities such as mud, sand and stones will affect the growth of plants and the beauty of the garden. Therefore, a device that can quickly and effectively separate sand and gravel is needed. The existing separation devices are usually large, inconvenient to move and transport, and complicated to operate, and cannot meet the needs of garden greening project construction sites.

[0003] The authorization announcement number in the prior art is: CN219765963U, and the name is a small sand and gravel separation device for landscaping engineering construction, including two supporting shells, a screening frame, a screen, a connecting frame, a first motor, a dispersion plate and other parts. The screening frame is arranged above the two supporting shells, and the bottom surface of the screen is fixed to the screening frame by screws. The connecting frame is fixed between the two supporting shells, and the first motor is installed inside the connecting frame, and a dispersion plate is fixedly installed at its output end. Two sliding holes are provided on the upper surface of each supporting shell, and the sand and gravel are separated by the screen. The second motor drives the cam to rotate so that the screening frame performs screening and separation. When the sand and gravel pass through the screen, the first motor drives the dispersion plate to rotate to throw the sand and gravel away to avoid accumulation under the screen. However, when the patent is in use, there is no protective device, which will not only cause the fallen sand and gravel to be thrown everywhere, but also cause a lot of dust, which is easy to affect the health of the operating workers.

[0004] The authorization announcement number in the prior art is: CN206794099U, and the name is a movable small-scale sand and gravel separation device, which includes a separation drum and a base. A drum bracket and a baffle bracket are welded on the upper part of the base. A bearing seat is arranged on the upper part of the drum bracket. A rotating shaft is installed between the two bearing seats. A group of reinforcing rings are evenly connected to the rotating shaft. The outer arc surface of the reinforcing ring is fixedly connected to the inner arc surface of the separation drum. A curved baffle is placed on the baffle bracket. This patent can improve the sand and gravel separation efficiency and avoid deformation of the separation drum. However, this patent also uses the separation drum for swinging separation during use, which can easily throw out some smaller ones, making the overall dust larger. Utility Model Content

Through the arrangement of structures such as the motor and the rotating shaft 9, sand and gravel are poured into the interior of the material box 6, and the output end of the motor drives the rotating shaft 9 to rotate through the coupling, so that the telescopic rod 19 knocks and vibrates the filter screen 14 to separate the sand and gravel, and the stirring rod 15 rotates accordingly, which will prevent the sand and gravel from accumulating inside the material box 6, thereby making the sand and gravel separation efficiency higher.

[0022] See also Figure 1 The top of the material box 6 is movably hinged with a cover plate 7, and the top of the cover plate 7 is fixedly connected with a handle 8 by screws. Through the arrangement of the material box 6 and the cover plate 7 and other structures, a large amount of dust will be generated when sand and gravel are separated. Therefore, after the sand and gravel are poured into the material box 6, the cover plate 7 is hung up so that the dust will not be scattered when the inside is screened, thereby achieving a better protection effect.

[0023] See also Figure 1-3 A filter screen 14 is arranged inside the material box 6, the stirring rod 15 is located above the filter screen 14, the rotating shaft 9 is located below the filter screen 14, the telescopic rod 19 is in contact with the filter screen 14, a baffle 13 is slidably mounted on one side of the material box 6, the baffle 13 is located on one side of the filter screen 14, a groove is provided inside the material box 6, a large pulley 16 and a small pulley 18 are both rotatably installed inside the groove, the material box 6 is located above the conveyor belt 2, and the bottom of the material box 6 does not contact the conveyor belt 2.

[0024] The specific implementation process of the utility model is as follows: first, pour the sand and gravel to be separated into the inside of the material box 6, and then turn on the power of the motor. The output end of the motor drives the shaft 9 to rotate through the coupling. Since the shaft 9 is provided with a telescopic rod 19, when the shaft 9 rotates, the telescopic rod 19 knocks and vibrates the filter screen 14, so that the sand and gravel are separated. The driving wheel 10 at one end of the shaft 9 drives the driven wheel 12 to rotate through the synchronous belt 11, so that the conveyor belt 2 moves, so that the sand and gravel falling through the filter screen 14 is taken out by the conveyor belt 2, making transportation more convenient. The small pulley 18 drives the large pulley 16 to rotate through the belt 17, so that the stirring rod 15 also rotates together, so that the sand and gravel accumulated on the top of the material box 6 will not be blocked, thereby improving the work efficiency;

[0025] Furthermore, a large amount of dust will be generated during use, so a cover plate 7 is provided on the top of the material box 6. When sand and gravel are poured into the material box 6, the cover plate 7 is closed to prevent dust from escaping from the top, thereby achieving a better protection effect. The bottom of the bracket 1 is fixedly connected with four connecting frames 3 by bolts, and a roller 4 is rotatably installed on one side of the connecting frame 3, which can be moved by the roller 4, making it more convenient to move and use.
