DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0031] Please refer to Figures 1-6 The utility model provides a kind of technical scheme: a kind of natural sand and gravel screening device of anti-blocking, including stirring box 1, feeding pipe 2, screening box 3, first filter screen 4, second filter screen 5, feeding port 6, first connecting shaft 7, first motor 8, connecting plate 9, belt 10, second connecting shaft 11, second motor 12, collision roller 13, third connecting shaft 14, third motor 15, first stirring rod 16, second stirring rod 17, air storage pipe 18, air inlet pipe 19 and spray pipe 20.

[0032] Embodiment 1: the existing hot air is blown to sand and gravel through hot air pipe, and it is uneven to enter, and sand and gravel are scattered and stirred by stirring shaft, but the stirring is insufficient, so the following technical solutions are used in the embodiment, such as Figure 1 、 Figure 3 and Figure 5The lower end of the third connecting shaft 14 is fixedly connected with the first stirring rod 16 at equal angles, and the upper end of the first stirring rod 16 is integrally connected with the second stirring rod 17 at equal intervals. The first stirring rod 16 and the second stirring rod 17 are in a rotating structure in the interior of the stirring box 1 through the third connecting shaft 14. The lower end of the air storage pipe 18 is threadedly connected with the spray pipe 20 at equal angles. The air inlet pipe 19 is connected in communication with the stirring box 1 through the air storage pipe 18 and the spray pipe 20. Therefore, the natural gravel enters the interior of the stirring box 1 through the feeding port at the upper left end of the stirring box 1. The third motor 15 drives the third connecting shaft 14 to rotate in the interior of the stirring box 1. The third connecting shaft 14 drives the first stirring rod 16 arranged at equal angles and the second stirring rod 17 arranged at equal intervals to rotate. The first stirring rod 16 arranged at equal angles and the second stirring rod 17 arranged at equal intervals rotate to stir the gravel in the interior of the stirring box 1, preventing the gravel from caking. Hot air enters the interior of the air storage pipe 18 through the air inlet pipe 19. The hot air in the air storage pipe 18 is uniformly blown into the interior of the stirring box 1 through the spray pipe 20 arranged at equal angles. When the first stirring rod 16 and the second stirring rod 17 stir the gravel, the hot air can uniformly contact the gravel, so that the hot air uniformly dries the gravel.

[0033] In the prior art, the first vibrating motor and the second vibrating motor are used to vibrate the screen to prevent blockage. However, two vibrating motors are needed to complete the vibration, which increases the cost. Therefore, in the embodiment, the following technical solutions are used. Figure 1 、 Figure 2 and Figure 4 The vibration structure includes the second connecting shaft 11, the second motor 12 and the collision roller 13. The intersection point of the collision roller 13 and the second connecting shaft 11 is not the same as the center of the collision roller 13. The collision roller 13 is in a rotating structure in the interior of the screening box 3 through the second connecting shaft 11. Therefore, the control valve on the discharge pipe 2 is opened after the gravel is dried, so that the gravel in the stirring box 1 enters the interior of the screening box 3 through the discharge pipe 2. The first filter screen 4 and the second filter screen 5 screen the gravel respectively. The second motor 12 drives the second connecting shaft 11 to rotate in the interior of the screening box 3. The second connecting shaft 11 drives the collision roller 13 to rotate. The collision roller 13 collides with the first filter screen 4 and the second filter screen 5 respectively when rotating, so that the first filter screen 4 and the second filter screen 5 vibrate, preventing the gravel from being blocked in the mesh structure of the first filter screen 4 and the second filter screen 5, thereby preventing the screen from being blocked.

[0034] In the prior art, the first opening and the second opening are in an open state. When the first filter screen and the second filter screen screen the gravel, the gravel is discharged through the openings, which causes waste. Therefore, in the embodiment, the following technical solutions are used. Figure 1 、 Figure 2 and Figure 6Since the shielding structure comprises the discharge port 6, the first connecting shaft 7, the first motor 8, the connecting plate 9 and the belt 10, the right lower end and the left lower end of the screening box 3 are provided with the discharge port 6, the front ends of the left and right groups of the first connecting shaft 7 are drivingly connected through the belt 10, the connecting plate 9 is inlaid at equal angles on the outer surface of the first connecting shaft 7, the front end diameter of the right first connecting shaft 7 is smaller than that of the left first connecting shaft 7, the connecting plate 9 is in a rotating structure inside the discharge port 6 through the first connecting shaft 7 and the belt 10, therefore, the first motor 8 drives the right first connecting shaft 7 to rotate when working, the right first connecting shaft 7 drives the left first connecting shaft 7 to rotate through the belt 10 when rotating, the connecting plate 9 rotates when the first connecting shaft 7 rotates, the connecting plate 9 is in a vertical state and does not block the discharge port 6, so that the first filter screen 4 and the second filter screen 5 do not drop the gravel on the ground when filtering the gravel, the left and right groups of the first connecting shaft 7 drive the connecting plate 9 to rotate when rotating when discharging, and the impact roller 13 rotates to vibrate the first filter screen 4 and the second filter screen 5, so as to accelerate the discharging speed, thereby preventing the gravel from falling on the ground during screening, and the electrical elements contained in the above are prior art, which will not be described in detail.

[0035] The standard parts used in the utility model can be purchased from the market, the special-shaped parts can be ordered according to the description and the drawings, the specific connection mode of each part adopts the conventional means such as bolts, rivets and welding in the prior art, the machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts the conventional connection mode in the prior art, which will not be described in detail.

[0036] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement and the like within the spirit and principle of the utility model should be included in the protection scope of the utility model.
