DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] In the embodiment, Figure 1-5 A sand and stone screening device for construction is given. The utility model includes a base 1, a first support plate 2 is fixedly connected to the top of the base 1, a screening plate 3 is rotatably connected to the top of the first support plate 2, a first motor 4 is fixedly connected to the outer side of the screening plate 3, a threaded rod 5 rotatably connected to the outer side of the screening plate 3 is fixedly connected to the outer side of the output shaft of the first motor 4, a transmission block 6 is connected to the outer side of the threaded rod 5 through a threaded transmission, a first connecting plate 7 is fixedly connected to the outer side of the transmission block 6, a cleaning plate 8 slidably connected to the outer side of the screening plate 3 is fixedly connected to the outer side of the first connecting plate 7, a second support plate 9 is fixedly connected to the top of the base 1, a support frame 10 is fixedly connected to the outer side of the second support plate 9, two fixed plates 11 are fixedly connected to the inside of the support frame 10 and are symmetrically distributed front and back, and connecting rods 12 are respectively rotatably connected to the front and rear sides of the screening plate 3 on the outer sides of the two fixed plates 11.
[0029] The rear side of the screening plate 3 is fixedly connected with a sliding rod 13 , the outer side of the sliding rod 13 is slidably connected with a sliding sleeve 14 , and the outer side of the sliding sleeve 14 is fixedly connected with a second connecting plate 15 fixedly connected to the outer side of the cleaning plate 8 .
[0030] In this embodiment, during actual use, when the first motor 4 drives the cleaning plate 8 to move, the sliding sleeve 14 will slide outside the sliding rod 13 at the same time. The sliding rod 13 stabilizes the moving direction of the sliding sleeve 14 and provides support for the movement of the cleaning plate 8.
[0031] The two fixing plates 11 are fixedly connected to the opposite sides thereof with sleeves 16 which are slidably connected to the outer sides of the two connecting rods 12 , and the tops of the two connecting rods 12 are fixedly connected to baffles 17 which are located above the two sleeves 16 .
[0032] In this embodiment, during actual use, as the screening plate 3 rises and falls, the connecting rod 12 moves up and down in the sleeve 16 , and the baffle 17 limits the moving distance of the connecting rod 12 .
[0033] The areas of the two baffles 17 are respectively larger than the inner diameters of the two sleeves 16 , and a clamping plate 18 is arranged inside the screening plate 3 .
[0034] In this embodiment, during actual use, the baffle 17 will rise and fall under the movement of the sleeve 16, and will collide with the sleeve 16 when falling. The clamping plate 18 can be activated to slow down the speed of small gravel flowing down, and the impact on large gravel is relatively small.
[0035] A plurality of screening holes are provided inside the screening plate 3 , and a cleaning brush 22 is provided inside the cleaning plate 8 .
[0036] In this embodiment, in actual use, the screening holes are used to screen and drop sand and gravel, and the cleaning brush 22 is a soft brush that can clean the inside of the screening plate 3.
[0037] The second motor 19 is fixedly connected to the top of the second support plate 9 , a cam 20 is fixedly connected to the outer side of the output shaft of the second motor 19 , and an arc plate 21 slidably connected to the cam 20 is fixedly connected to the bottom of the screening plate 3 .
[0038] In this embodiment, during actual use, the second motor 19 drives the cam 20 to rotate, and the rotating cam 20 contacts the arc plate 21 to lift the screening plate 3 .
[0039] Working principle:
[0040] Unscreened sand and gravel are poured from the screening plate 3. When the cleaning plate 8 is at the far left, the sand and gravel placement position can be set to the right side of the cleaning plate 8 to prevent the cleaning plate 8 from blocking the sand and gravel on the screening plate 3. The start of the second motor 19 will drive the cam 20 to rotate, thereby achieving the effect of the screening plate 3 rotating up and down. When the screening plate 3 descends, the baffle 17 will be blocked by the sleeve 16. The vibration generated by the collision will cause the sand and gravel to move to the right, and the sand and gravel will fall from the screening hole. The sand and gravel that has not fallen will be blocked by the card plate 18 for a moment and continue to be screened. The stone particles will roll down from the right side of the screening plate 3, and some of the sand and gravel carried by the stone particles can be screened for the second time. Start the first motor 4, and the rotation of the threaded rod 5 will drive the cleaning plate 8 to move, so that the cleaning brush 22 cleans the sand and gravel remaining on the inner wall of the screening plate 3.
