In the utility model, the open amount of dodge gate be can control by handle, and then discharge quantity and the speed of sand controlled; prevent the unexpected stressed breakage of screen cloth; can cushion the gravity of sand simultaneously by damping spring, further extend the service life of screen cloth, reduce the frequency of shutting down maintenance.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of hopper and handle.
Fig. 3 is belt conveyor and support roller distribution schematic diagram.
Wherein: 1. support, 2. conveyer belt main shaft, 3. belt conveyor, 4. hopper, the upper bucket body of 4-1., bucket body under 4-2., 5. screen cloth bracing frame, 6. vibrating motor, 7. shock-absorbing spring, 8. wheel, 9. handle, 10. second connecting rod, 11. first connecting rods, 12. dodge gates, 13. connecting axles, 14. support rollers.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figures 1 to 3, a kind of vibration sand sieving machine, comprises support 1 and hopper 4, support 1 bottom is provided with wheel 8, support 1 is provided with belt conveyor 3, between hopper 4 and belt conveyor 3, is provided with screen device, and described hopper 4 bottoms are provided with dodge gate 12, dodge gate 12 is hinged and connected with head rod 11, first connecting rod 11 is hinged and connected with second connecting rod 10, and second connecting rod 10 is connected with connecting axle 13, and connecting axle 13 is connected with handle 9, connecting axle 13 is arranged in sleeve, and sleeve is fixed on support 1.
The utility model course of work is as follows: first sand to be screened is put into hopper 4, and swing handle 9 afterwards, second connecting rod 10 is followed handle 9 and is rotated, and second connecting rod 11 is followed second connecting rod 10 and is rotated, and then drives dodge gate 12 to move up and down.When dodge gate 12 moves up, the feed opening of hopper 4 is opened, and sand drops on screen device screened, and the sand after screening drops on belt conveyor 3 and transported.By the rotational angle of handle 9, the position of dodge gate 12 can be controlled, and then the discharge quantity of hopper 4 can be controlled, sand is dropped on screen device uniformly, while preventing the stressed sudden change of screen device, screen cloth damages.
As further preferred, described hopper 4 comprises bucket body 4-1 and lower bucket body 4-2, between upper bucket body 4-1 and lower bucket body 4-2, is connected by flange.Hopper 4 is divided into upper and lower two parts, is relatively convenient to assembling, transport and the maintenance of complete machine.Preferably, dodge gate 12 is arranged on lower bucket body 4-2.
