Technical Field
[0001] The utility model relates to the technical field of garden greening project construction, in particular to a small sand and gravel separation device for garden greening project construction. Background Art
[0002] Small sand and gravel separator for landscaping construction is a kind of equipment specially used for landscaping construction. Its main function is to separate sand and gravel. This kind of equipment is usually small in size, which is convenient for moving and using at the construction site of landscaping projects. Its working principle is mainly to separate the mixed sand and gravel through mechanical force or electric drive, so that pure sand and gravel can be used in the construction process.
[0003] The existing authorization announcement number is CN219765963U, which discloses a small sand and gravel separation device for landscaping engineering construction, including two support shells, a screening frame is provided on the top of the two support shells, a screen is fixedly installed on the bottom of the screening frame by screws, a connecting frame is fixedly connected between the two support shells, a first motor is fixedly installed inside the connecting frame, a dispersion plate is fixedly installed at the output end of the first motor, and two sliding holes are provided on the upper surface of each support shell. The device is provided with a screening frame on the top of the two support shells, a screen is provided at the bottom of the screening frame, and the sand and gravel are separated by the screen. A cam is provided at the bottom of the screening frame, and the second motor drives the cam to rotate through a rotating shaft, so that the screening frame can screen and separate the sand and gravel. When the sand and gravel pass through the screen, the dispersion plate is driven to rotate by the first motor provided below the screen, and the sand and gravel are thrown away by the dispersion plate to avoid accumulation under the screen.
[0004] The above technical solution avoids the accumulation of screened sand and gravel under the screen, but in the long-term screening process of the screen, the grid may be blocked by fine sand and gravel, which leads to a decrease in screening efficiency. Secondly, most traditional screens are integrated with the device or installed with screws, which requires more time and effort to disassemble and clean the screen, prolonging the downtime of the device and reducing work efficiency. Therefore, we provide a small sand and gravel separation device for landscaping engineering construction. Utility Model Content

The mounting blocks 12 and the slots opened at the top of the limit block 18 are fixedly connected with mounting shells 17, and sliders 15 are fixedly connected on both sides of the screening plate 13. The outside of the slider 15 is slidably connected to the inner wall of the slide groove 16, and the four mounting shells 17 are fixedly connected to the mounting block 12 and the slots opened at the top of the limit block 18. A block 19 is provided at the top, and a movable rod 110 is provided at the bottom of the four blocks 19. One end of the screening plate 13 passes through the slot opened on one side of the mounting block 12 and docks in the screening frame 11. The bottom of the block 19 contacts the top of the mounting shell 17. The top of the movable rod 110 is movably connected to the inside of the block 19. Reset springs 111 are provided on the outside of the four movable rods 110. Positioning columns 112 are provided at the bottom of the four movable rods 110. The bottom of the movable rod 110 passes through the slot and the reset spring 111 opened at the top of the mounting shell 17. The inner ring is fixedly connected to the top of the positioning column 112, the top of the return spring 111 is fixedly connected to the top side of the inner wall of the mounting shell 17, the bottom end of the return spring 111 is fixedly connected to one end of the positioning column 112 close to the movable rod 110, and the bottom end of the positioning column 112 is clamped in the positioning groove 14. The vibration motor 31 is fixedly connected to both sides of the bottom of the screening frame 11, and the four corners of the bottom of the screening frame 11 are fixedly connected with springs 32. The bottom of the four springs 32 is fixedly connected to the top of the counterweight block 33, and a collecting mechanism 2 is provided at the bottom of the screening frame 11.
[0025] When the screen plate 13 is completely filled in the screening frame 11, the positioning groove 14 can be kept in the same vertical plane with the positioning column 112, so that the screen plate 13 can be removed from the screening frame 11 and the screening grid 13 can be cleaned by the positioning block 12.
[0026] like Figure 1 and Figure 4 As shown, the collecting mechanism 2 includes a collecting box 21, and pulleys 23 are fixedly installed at the four corners of the bottom of the collecting box 21.

The collecting box 21 will collect the screened sand and gravel. However, the grid of the screening plate 13 may be clogged with sand and gravel and needs to be cleaned. The staff can accordingly push the four push blocks 19 upward. When the push blocks 19 are pushed, the movable rod 110 and the positioning column 112 will be forced to move upward, and then the positioning column 112 will be disengaged from the positioning groove 14 and recessed into the mounting shell 17. The return spring 111 will be squeezed by the recess of the positioning column 112 to produce a contraction deformation, and then the staff can easily take out the screening plate 13 from the side of the screening frame 11 close to the mounting block 12 to clean the grid blocked on the surface.
