Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of corn screening equipment, and in particular relates to a corn cleaning screen structure. Background Technology
[0002] When corn is collected by machine, it often contains impurities and particles, requiring screening to separate the clean corn kernels for collection and storage. Current screening equipment discharges large impurities from one side and small impurities from the other, requiring separate collection, which is cumbersome. Furthermore, the corn kernels discharged from the large-diameter discharge plate at the front of the screening equipment easily scatter on the ground, requiring cleaning and increasing workload. Utility Model Content
[0003] To address the above problems, this utility model provides a corn cleaning screen structure.
[0004] This utility model is implemented as follows: A corn cleaning screen structure includes a frame, within which a screen frame is fixedly installed at an incline downwards to ensure its stability. A hopper is fixedly installed at the upper end of the frame, high up on the screen frame. A vibrating motor is fixedly installed at the lower end of the screen frame. When the vibrating motor is activated, corn kernels mixed with impurities are poured into the hopper and then fall into the screen frame. The screen frame is a rectangular shell with an open top. A first partition is fixedly installed at an incline downwards in the upper part of the screen frame to separate corn kernels from large impurity particles. The first partition is densely covered with first screen holes, through which corn kernels fall. A first discharge hole is opened between the lower part of the first partition and the inner wall of the screen frame, through which large impurity particles fall. A second partition is fixedly installed at an incline downwards in the lower part of the screen frame to separate corn kernels from small impurity particles. The second partition is densely covered with second screen holes, through which small impurity particles fall. The diameter of the second screen holes is smaller than that of the first screen holes, ensuring that the corn kernels remain in the first screen hole. On the second partition, a second discharge hole is provided between the lower part of the second partition and the inner wall of the screen frame to facilitate the falling of large impurity particles. A third discharge hole is provided at the lower end of the screen frame to facilitate the falling of both large and small impurity particles discharged along the second screen hole. The first, second, and third discharge holes are vertically connected to ensure the smooth falling of both large and small impurity particles. A baffle is vertically installed at the upper end of the lower part of the second partition, and the two ends of the baffle are connected to... The inner wall of the screen frame is fixedly connected to ensure the stability of the baffle position. A through groove is opened between the lower end of the baffle and the second partition. The height of the through groove is 0.1mm to 0.3mm. The baffle blocks the corn kernels, while allowing small particles of impurities located at the lower part of the second partition to pass through the through groove and be discharged from the second discharge hole, ensuring the reliable quality of the collected corn kernels. A discharge hole is opened on the side wall of the screen frame located at the lower part of the second partition and close to the baffle. The corn kernels at the lower part of the second partition are discharged along the discharge hole.
[0005] Preferably, a discharge cylinder is vertically fixed at the lower end of the screen frame located below the third discharge hole, which facilitates the collection of impurity particles by placing the collection bag on the discharge cylinder, making the operation convenient.
[0006] Preferably, a discharge plate is fixedly installed at an angle downwards on the outer wall of the screen frame located at the discharge hole, which facilitates the collection of corn kernels by placing the collection bag on the discharge plate and avoids the corn kernels from spilling.
[0007] Preferably, the first and second partitions are arranged parallel to each other and tilted at an angle of 15 to 35°, which prolongs the residence time and ensures the removal effect of impurity particles.
[0008] Preferably, the angle between the baffle and the side wall of the screen frame is 60-80°. The baffle blocks the corn kernels, and the inclined setting makes it easier for the corn kernels to be discharged from the second partition when they move to the lower part of the second partition.
[0009] The beneficial effects of this utility model are as follows: The structural design of this utility model is relatively novel. The first partition separates the corn kernels from large impurity particles. The corn kernels fall through the first screen hole, and the large impurity particles fall through the first discharge hole. The second partition separates the corn kernels from small impurity particles. The small impurity particles fall through the second screen hole. The diameter of the second screen hole is smaller than that of the first screen hole, ensuring that the corn kernels remain on the second partition. A third discharge hole is provided at the lower end of the screen frame, which facilitates the falling of both large impurity particles and small impurity particles discharged through the second screen hole. The first discharge hole and the third discharge hole are connected in the vertical direction, and the collection of impurity particles can be completed through a single outlet. The operation is convenient, time-saving, and labor-saving. A discharge hole is provided on the side wall of the screen frame at the lower end of the second partition and near the baffle, which facilitates the collection of corn kernels and avoids the occurrence of corn kernel spillage.

[0015] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.
[0016] like Figure 1-4The corn cleaning screen structure shown includes a frame 1. A screen frame 2 is fixedly installed at an incline downwards inside the frame 1 to ensure its stability. A hopper 3 is fixedly installed at the upper end of the frame 1, above the screen frame 2. A vibration motor 4 is fixedly installed at the lower end of the screen frame 2. When the vibration motor 4 is activated, corn kernels mixed with impurities are poured into the hopper 3 and then fall into the screen frame 2. The screen frame 2 is a rectangular shell with an open upper end. A first partition 5 is fixedly installed at an incline downwards in the upper part of the screen frame 2 to separate the corn kernels from large impurity particles. The first partition 5 is densely covered with first screen holes 6, through which the corn kernels fall. The lower part of the first partition 5 is flush with the screen. A first discharge hole 7 is provided between the inner walls of the frame 2. Large impurity particles fall down along the first discharge hole 7. A second partition 8 is fixedly installed at the lower part of the screen frame 2 at an incline to separate corn kernels from small impurity particles. The second partition 8 is densely covered with second screen holes 9. Small impurity particles fall down along the second screen holes 9. The diameter of the second screen holes 9 is smaller than the diameter of the first screen holes 6, ensuring that the corn kernels remain on the second partition 8. A second discharge hole 10 is provided between the lower part of the second partition 8 and the inner wall of the screen frame 2 to facilitate the falling of large impurity particles. The first partition 5 and the second partition 8 are arranged parallel to each other and at an inclination angle of 25°, which prolongs the residence time and ensures the removal effect of impurity particles. A third discharge hole 11 is provided at the lower end of the screen frame 2, which facilitates the drop of large impurity particles as well as the drop of small impurity particles discharged along the second screen hole 9. The first discharge hole 7, the second discharge hole 10 and the third discharge hole 11 are connected in the vertical direction to ensure the smooth drop of large and small impurity particles. A discharge cylinder 15 is vertically fixed at the lower end of the screen frame 2 below the third discharge hole 11, which facilitates the collection of impurity particles by putting the collection bag on the discharge cylinder 15, making the operation convenient. A baffle 12 is vertically installed at the upper end of the lower part of the second partition 8. Both ends of the baffle 12 are fixedly connected to the inner wall of the screen frame 2 to ensure the stability of the baffle 12's position. A through groove 13 with a height of 0.2 mm is formed between the lower end of the baffle 12 and the second partition 8. The baffle 12 blocks the corn kernels while allowing small particles of impurities located at the lower part of the second partition 8 to pass through the through groove 13 and be discharged from the second discharge hole 10, ensuring the reliable quality of the collected corn kernels. A discharge hole 14 is formed on the side wall of the screen frame 2 located at the lower part of the second partition 8 and close to the baffle 12. The corn kernels at the lower part of the second partition 8 are discharged along the discharge hole 14. The angle between the baffle 12 and the side wall of the screen frame 2 is 70°. The baffle 12 blocks the corn kernels, and its inclined design makes it easier for the corn kernels to be discharged from the second partition 8 when they move to the lower part of the second partition 8. A discharge plate 16 is fixedly installed on the outer wall of the screen frame 2 located at the discharge hole 14, which is inclined downwards. This makes it easy to put the collection bag on the discharge plate 16 to collect the corn kernels and avoid the corn kernels from spilling.
