[0020] The following is combined with Figure 1-Figure 3 This application is described in further detail.
[0021] Embodiment 1
[0022] Reference Figure 1-Figure 3, a cleaning-free dust-free suction machine includes a suction tank 1, a fan 2 is installed on the top of the suction tank 1 through a base, in order to enable the device to suck materials from the outside, the power input end of the fan 2 is connected to the power output end of the outside, and the air inlet end of the fan 2 extends through the inside of the suction tank 1, and a partition 3 is welded in the middle of the inside of the suction tank 1. In order to change the direction of the material entering the suction tank 1, a filter chute 4 is opened on one side of the suction tank 1, and a filter plate 5 is slidably embedded in the inside of the filter chute 4. In order to prevent the floating material from entering the fan 2, the outer side of one end of the filter plate 5 is in contact with the outer surface of the suction tank 1, and an air suction pipe 6 is connected to the outer side of one end of the suction tank 1. The air inlet end of the fan 2 and the air outlet end of the suction pipe 6 are respectively distributed on both sides of the partition 3, and the air inlet end of the suction pipe 6 is connected to a folding pipe 7, in order to extend the length of the feeding mechanism;
[0023] A turntable 8 is rotatably connected to the bottom end of the suction tank 1, and a closed baffle 12 is welded to the middle of the inner side of the turntable 8. A discharge funnel 9 is rotatably connected to the bottom end of the turntable 8 through a bearing 10. A discharge hole 11 is penetrated through the bottom end of the suction tank 1 and the top end of the closed baffle 12. In order to be able to adjust the discharge conditions of the material inside the suction tank 1, a discharge pipe 13 is welded to the bottom end of the discharge funnel 9. In order to be able to output the material to the outside and realize the transfer of the material, a discharge plug 14 is slidably embedded in the bottom end of the inner side of the discharge pipe 13. The discharge limiter 15 is a bolt limiter, and one end of the discharge limiter 15 penetrates the discharge pipe 13 and fits the outer surface of one end of the discharge plug 14, and a discharge limiter 15 is installed on the outer side of one end of the discharge pipe 13.
[0024] Working principle: First, the operator stretches the folding tube 7 connected to the air inlet end of the suction pipe 6 welded at one end of the suction tank 1, and inserts the air inlet end of the folding tube 7 into the material to be transferred. Then the operator starts the fan 2, and the fan 2 will then draw air toward the inside of the suction tank 1. Since the suction tank 1 has only one air inlet at this end of the suction pipe 6, the suction pipe 6 will draw air outward through the folding tube 7 connected thereto, and draw the external material into the suction tank 1. At that time, the partition 3 welded inside the suction tank 1 can change the movement route of the feed, and the material will fall to the bottom of the suction tank 1 due to its own weight after being blocked by the partition 3, and since the material does not block the distance between the air inlet end of the fan 2 inside the suction tank 1 and the air outlet end of the suction pipe 6, the material accumulated at the bottom of the suction tank 1 will continue to accumulate at the bottom of the suction tank 1.
[0025] After a certain amount of material is accumulated at the bottom of the inner side of the suction tank 1, the operator rotates the turntable 8. At that time, the turntable 8 will rotate because of the rotation connection with the bottom of the suction tank 1, and as the rotation proceeds, the closed baffle plate 12 welded in the middle of the inner side of the turntable 8 will also rotate relative to the bottom of the suction tank 1. At the same time, the relative positions of the closed baffle plate 12 and the discharge hole 11 through the bottom of the inner side of the suction tank 1 will gradually overlap. After the discharge hole 11 overlaps, the material accumulated at the bottom of the inner side of the suction tank 1 will fall into the discharge funnel 9 along the discharge hole 11. Moreover, since the amount of material accumulated at the bottom of the inner side of the suction tank 1 is relatively large, the material in the suction tank 1 The part will not be ventilated relative to the discharge funnel 9 due to the reduction of material, thereby not affecting the air flow inside the suction tank 1. Then the operator loosens the discharge limiter 15, and then pulls out the discharge plug 14 that has lost the limit of the discharge limiter 15 from the inside of the discharge pipe 13. At that time, the material inside the discharge funnel 9 will be discharged to the outside along the discharge pipe 13, and because the discharge amount of the discharge hole 11 is less than the feed amount of the suction pipe 6, the material accumulated at the bottom end of the inner side of the suction tank 1 will gradually increase and will not decrease. This design can complete the material transfer without passing through the fan 2, and can avoid the fan 2 from being cleaned after long-term use.
[0026] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
