Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression during grain unloading, in particular to a dust prevention grain unloading mechanism. Background Art

[0002] Patent publication number CN212126874U discloses a grain unloading dust suppression device, including a dust collector installed on the roof platform of the grain unloading station; a plurality of dust removal bellows symmetrically arranged on both sides of the grain unloading pit, the dust removal bellows are connected to the dust collector through a dust removal pipeline; and an automatic dust suppression hood foldably arranged at the end of the grain unloading pit. When unloading grain into the grain unloading pit, the automatic dust suppression hood is unfolded to cover the rear of the bulk grain truck, the grain unloading pit and the grain flow to prevent the outside air flow from raising the dust in the grain flow, while reducing the dust removal space of the dust removal bellows and improving the dust removal effect. The dust removal bellows on both sides of the automatic dust suppression hood perform negative pressure dust removal on both sides of the grain unloading pit. The dust removal bellows are connected to the dust removal pipeline and are connected to the dust collector. The dust-containing air collected by the dust removal bellows is sent to the dust collector through the dust removal pipeline for filtration and purification, and finally the clean air is discharged into the atmosphere.

[0003] The above technology sucks the raised dust into the dust collector for purification by suction, and then discharges the purified air into the atmosphere. In this method, the dust collector is used too frequently, the required suction power is too large, and the filter needs to be cleaned frequently, which will result in a short service life of the dust collector and excessively high cost of use. Utility Model Content

[0004] The utility model aims to provide a dust-proof grain unloading mechanism.

[0005] The technical problem solved by the utility model is that the cost of treating the raised dust is too high when treating the raised dust by dust suction and purification.

[0006] The utility model can be realized through the following technical scheme: a dust-proof grain unloading mechanism comprises a collecting box, a discharging pipe is fixedly connected to the bottom of the collecting box, sliding rods are slidably installed on both sides of the collecting box, a displacement plate is fixedly installed between the opposite ends of the two sliding rods, an annular groove is opened at the bottom of the displacement plate, a support plate is fixedly installed between the inner walls of both sides of the collecting box, a stirring assembly is installed on the support plate, a displacement frame is provided on the outside of the collecting box, one end of the sliding rod away from the displacement plate is fixedly connected to the inner wall of the displacement frame, a dust reduction assembly and an exhaust assembly are arranged in the collecting box from top to bottom, the dust reduction assembly is used for dust reduction treatment of raised dust, and the exhaust assembly is used for discharging dust fused with atomized liquid from the collecting box.

[0007] A further technical improvement of the utility model is that the top of the displacement plate is in the shape of a cone, so as to prevent the grains deposited in the collection box from hindering the movement of the displacement plate.

[0008] Furthermore, the stirring assembly includes a rotating rod that is rotatably installed on the support plate, the bottom end of the rotating rod extends into the discharge pipe, a first connecting plate is fixedly installed on the top of the rotating rod, the end of the first connecting plate away from the rotating rod is slidably connected to the annular groove, and a spiral blade is fixedly installed on the outer peripheral wall of the rotating rod.

[0009] Furthermore, the dust reduction component includes a drain pipe fixedly installed on the top of the inner cavity of the collection box, a plurality of atomizing nozzles are fixedly connected to the outer peripheral wall of the drain pipe, a water tank and a piston cylinder connected to the drain pipe are fixedly installed on the outside of the collection box, a piston rod is slidably installed through the end of the piston cylinder away from the drain pipe, a second connecting plate is rotatably installed on the end of the piston rod away from the piston cylinder, and the end of the second connecting plate away from the piston rod is rotatably connected to the top of the displacement frame.

[0010] Furthermore, a one-way water inlet valve is fixedly installed between the water tank and the drain pipe, so that the liquid in the drain pipe will not flow back into the water tank.

[0011] Furthermore, the exhaust assembly includes a plurality of fans rotatably installed on one side of the collection box, a gear is fixedly installed on one end of the fan that passes through the outside of the collection box, a rack is fixedly installed at a position near the gear on the top of the displacement frame, and the rack is meshed with a plurality of gears at the same time. An exhaust port is opened on the side of the collection box away from the fan, and the rack drives the gear to rotate, thereby driving the fan to rotate and discharge air, blowing the airflow toward the exhaust port.

[0012] Furthermore, a material separation mesh plate is fixedly installed on one side of the collection box adjacent to the fan to prevent bulk grain from being deposited on the fan and thus avoiding food waste.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The present application uses a reciprocating displacement frame to spray the liquid in the drain pipe to the top of the bulk grain discharge in an atomized state. The atomized liquid merges with the dust raised by the bulk grain, and the air flow driven by the rotating fan flows toward the exhaust port, and then the dust merged with the liquid is discharged from the collection box. The discharged dust achieves the effect of dust reduction due to its fusion with the liquid, thereby reducing the cost of use.

[0015] 2. The second connecting rod at the top of the rotating rod of the present application slides in the annular groove at the bottom of the displacement plate, so that the rotating rod drives the stirring blades to stir the grain in the discharge pipe, so that the grain can be discharged from the discharge pipe to the designated position faster, thereby improving work efficiency.

[0024] The displacement frame 10 drives the displacement plate 7 between the two slide bars 6 to reciprocate in the collection box 1 through the two slide bars 6. At this time, the end of the first connecting plate 9 slides along the annular groove 8 at the bottom of the displacement plate 7, so that the first connecting plate 9 drives the rotating rod 4 to rotate on the support plate 3, and then the rotating rotating rod 4 drives the stirring blade to rotate in the discharge pipe 2;

[0025] A plurality of fans 11 are rotatably installed on one side of the collection box 1, and a gear 12 is fixedly installed on one end of the fan 11 that passes through the outside of the collection box 1. A rack 13 is fixedly installed on the top of the displacement frame 10 near the gear 12, and the rack 13 meshes with the gear 12. A material separation mesh plate 14 is fixedly installed on the inner wall of the collection box 1 near the fan 11, and an exhaust port 15 is opened on the side of the collection box 1 corresponding to the material separation mesh plate 14;

[0026] While the displacement frame 10 is reciprocating, the rack 13 slides at the bottom of the gear 12 to drive the gear 12 to rotate. The rotating gear 12 drives the fan 11 to rotate, so that the airflow in the collection box 1 is blown toward the exhaust port 15 through the material separation mesh plate 14;

[0027] A drain pipe 16 is fixedly installed on the top of the inner cavity of the collection box 1, and a water tank 17 and a piston cylinder 18 connected to the drain pipe 16 are fixedly installed on the outside of the collection box 1.

At this time, the airflow fanned by the fan 11 drives the raised dust and the atomized liquid to flow toward the exhaust port 15, so that the raised dust is discharged from the collection box 1. While the displacement frame 10 reciprocates, it drives the displacement plate 7 to move, so that the end of the first connecting plate 9 slides in the annular groove 8 at the bottom of the displacement plate 7, and then the rotating rod 4 drives the stirring blade to rotate in the discharge pipe 2, so that the stirring blade stirs the grain in the discharge pipe 2, so that the grain can be quickly discharged from the discharge pipe 2.
