Description

Technical Field

[0001] This utility model relates to the field of impurity removal devices, and in particular to an impurity removal device for grain silos. Background Technology

[0002] As the name suggests, a grain silo impurity removal device is a device used to clean and sort impurities in grain. It is usually installed in grain silos or grain storage facilities to ensure grain quality and prevent impurities from affecting the grain storage environment or grain processing. During the process of grain entering the silo, the grain contains impurities such as rice husks and dust, which need to be cleaned.

[0003] In existing technologies, vibrating screens are commonly used for grain impurity removal. The combination of vibration and screen mesh effectively removes dust from the grain. However, vibrating screens have difficulty effectively separating rice husks. Because rice husks are similar in size to rice ears and are relatively light, they sit on top of the material on the screen and are therefore difficult to separate. Thus, a grain silo impurity removal device is needed to solve the problem of rice husk removal. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing grain cleaning equipment has difficulty removing lighter husks and dust.

[0005] The technical solution adopted by this utility model to solve the aforementioned problem is:

[0006] A grain silo impurity removal device includes a box for holding grain, a base for support below the box, multiple support rods fixedly connected to the outer edge of the top surface of the base, the top ends of the multiple support rods fixedly connected to an annular plate, a motor installed on the lower side of the annular plate, a shaft connected to the output end of the motor, multiple fan blades provided on the outer surface of the shaft, a cone block rotatably connected to the top end of the shaft, a cone shell fixedly connected to the outer surface of the cone block, a cone shell provided with uniformly distributed through holes, the outer edge of the cone shell fixedly connected to the inner edge of the annular plate, a box on the annular plate, a cover plate fixedly connected to the top of the box, multiple fixing holes opened on the top of the cover plate, a branch pipe fixedly connected to the inner wall of the fixing holes, a pump pipe connected to the outer end of the branch pipe, and a suction pipe connected to the inner end of the branch pipe.

[0007] Compared with the prior art, the advantages of this utility model with the above structure are:

[0008] This invention uses a motor to drive the fan blades, generating an upward airflow from the bottom of the housing. This airflow carries lighter rice husks and dust upwards, while the heavier rice grains fall freely without being affected by the airflow. This forms an upper layer of rice husks and dust and a lower layer of rice grains inside the housing. The upper layer of rice husks and dust is then discharged from the branch pipe by the suction force of the pump pipe, effectively removing lighter impurities from the grain.

[0009] As a preferred option, a further technical solution to the above structure is:

[0010] A material gap is provided between the top of the annular plate and the bottom of the box body; this facilitates the discharge of grain after impurity removal.

[0011] A bracket is fixedly connected to the outer surface of the support rod, and the outer surface of the bracket is fixedly connected to the outer surface of the box. This implementation supports the box through the support rod, realizes the reservation of material gaps, and achieves a simple structure.

[0012] An arc-shaped rod is installed between adjacent supports for connection; this example can increase the strength of the box support structure and improve the stability of the box.

[0013] A protective shell is provided between the base and the annular plate and around the motor; the protective shell can protect the motor and fan blades, and at the same time, it can also support the annular plate, increasing the structural stability of the equipment.

[0014] The bottom of the cover plate is fixedly connected to a fixed pipe, and the top of the cover plate is fixedly connected to a feed pipe; this facilitates material feeding and enables the equipment to produce continuously. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figures 1 to 4 This utility model provides a grain silo impurity removal device, including a base 1, a plurality of support rods 2 fixedly connected to the outer edge of the top surface of the base 1, the top ends of the plurality of support rods 2 fixedly connected to an annular plate 3, a motor 5 installed on the lower side of the annular plate 3, the output end of the motor 5 connected to a shaft 6, a plurality of fan blades 7 provided on the outer surface of the shaft 6, a cone block 8 rotatably connected to the top end of the shaft 6, a cone shell 9 fixedly connected to the outer surface of the cone block 8, a cone shell 9 provided with uniform through holes, the outer edge of the cone shell 9 fixedly connected to the inner edge of the annular plate 3, a box body 10 provided on the annular plate 3, a cover plate 11 fixedly connected to the top of the box body 10, a plurality of fixing holes opened on the top of the cover plate 11, a branch pipe 14 fixedly connected to the inner wall of the fixing holes, the outer end of the branch pipe 14 connected to a pump pipe 16, and the inner end of the branch pipe 14 connected to a suction pipe 15.

[0022] This scheme uses motor 5 to drive fan blade 7, generating an upward airflow from the bottom of housing 10. The airflow carries the lighter rice husks and dust upwards, while the heavier rice grains are not affected by the airflow and fall freely, forming an upper layer of rice husks and dust and a lower layer of rice grains inside housing 10. The upper layer of rice husks and dust is discharged from branch pipe 14 by the suction force of pump pipe 16.

[0023] In the above structure, the shaft 6 is rotatably connected to the bottom end of the cone block 8, and the cone block 8 is fixed by the cone shell 9, which can increase the structural stability of the shaft 6 and prevent the shaft 6 from bending.

[0024] Preferably, a material gap is provided between the top of the annular plate 3 and the bottom of the box body 10, the material gap being used to discharge rice from the box body. Optionally, the height of the material gap is 50mm to 100mm.

[0025] Optionally, a bracket 17 is fixedly connected to the outer surface of the support rod 2, and the outer surface of the bracket 17 is fixedly connected to the outer surface of the housing 10. Furthermore, an arc-shaped rod 18 is provided between adjacent brackets 17 for connection. The brackets 17 can support the housing 10, while the arc-shaped rods 18 can make the support of the brackets 17 more stable, increasing the structural stability of the equipment.

[0026] Optionally, a fixing pipe 12 is fixedly connected to the bottom of the cover plate 11, and a feed pipe 13 is fixedly connected to the top of the cover plate 11.

[0027] Optionally, a protective shell 4 is provided between the base 1 and the annular plate 3, and around the motor 5. The upper and lower ends of the protective shell 4 can be fixedly connected to the annular plate 3 and / or the base 1. The protective shell 4 can protect the motor 5 and the fan blade 7, and at the same time, it can also support the annular plate 3, increasing the structural stability of the equipment.

[0028] Working principle:

[0029] like Figure 1-4 As shown, during use, the motor 5 drives the shaft 6 to rotate, and the rotation of the shaft 6 drives the fan blade 7 to rotate, thereby increasing the wind pressure at the top of the fan blade 7. The gas moves upward through the filter holes of the cone shell 9, while the material enters from the feed pipe 13 and reaches the interior of the fixed pipe 12 under the action of gravity. Then the material falls from the bottom of the fixed pipe 12 and hits the top of the cone block 8 under the action of gravity, causing an impact and ejection phenomenon. At this time, the material falls around the cone block 8 in an umbrella shape. The upward airflow carries the dust and rice husks upward and, through the suction from multiple pump pipes 16, the rice husks and dust enter through the branch pipe 14 and the suction pipe 15. The dust and rice husks then enter the pump pipe 16 for collection through the branch pipe 14 and the suction pipe 15. The rice ears that fall around the cone block 8 slide outward through the cone shell 9 and the annular plate 3 under the action of gravity and are then discharged from the gap between the box 10 and the annular plate 3, thus completing the material removal work.

[0030] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
