Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, and more specifically, to a corn peeling device. Background Technology

[0002] In the corn processing industry, corn peeling is a crucial pre-processing step, and its efficiency and quality directly impact subsequent processing stages. Traditional corn peeling devices primarily employ a double-roller friction structure, using the relative motion of stationary and moving rollers to peel off the corn husks. However, existing technologies suffer from the following problems in practical applications: corn husk residue generated during peeling easily accumulates in the gap between or beneath the stationary and moving rollers. If not cleaned promptly, this can lead to roller slippage, incomplete peeling, and even equipment blockage, requiring frequent shutdowns for cleaning and severely impacting production efficiency. Some devices utilize dual motors or multiple transmission systems to drive the peeling rollers and cleaning mechanism, resulting in complex structures, high energy consumption, poor synchronization, and increased maintenance costs and failure rates. Utility Model Content

[0003] The present invention provides a corn peeling device that can synchronously drive peeling and slag blowing functions with a single motor, and optimizes the guidance of peeling and slag and the adjustability of the equipment.

The blower mechanism includes a rotating shaft rotatably mounted on the frame and located below the stationary roller assembly, and a fan blade mounted on the rotating shaft. The drive motor is connected to the rotating shaft and the moving roller assembly via a synchronous belt transmission mechanism.

[0006] Preferably, the synchronous belt drive mechanism includes a first synchronous pulley, a second synchronous pulley, a third synchronous pulley, and a synchronous belt that drives the three synchronous pulleys together; the first synchronous pulley is mounted on the motor shaft of the drive motor, the second synchronous pulley is mounted on the rotating shaft; the third synchronous pulley is mounted on a wheel axle that is rotatably fitted to the frame, and the wheel axle is driven to the roller shaft end of the moving roller assembly through a gear transmission group.

[0007] Preferably, the frame is equipped with a corn husk discharge guide plate located directly below the stationary roller assembly and the moving roller assembly and inclined to the side, and the rotating shaft is located obliquely above the upper end of the corn husk discharge guide plate.

[0008] Preferably, the support legs at the lower end of the frame supporting the stationary roller assembly and the moving roller assembly are provided with adjustable lifting legs.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0024] Please refer to Figures 1-5 This embodiment provides a corn peeling device, including a frame 8, on which an inclined stationary roller assembly 12, an inclined moving roller assembly 13, a corn cob feed hopper 5 corresponding to the upper end of the moving roller assembly 13, a corn cob outlet guide plate 2 corresponding to the lower end of the moving roller assembly 13, a drive motor 10 for driving the moving roller assembly 13 to rotate, and a blower mechanism for blowing away corn husk residue. The blower mechanism includes a rotating shaft 6 rotatably mounted on the frame 8 and located below the stationary roller assembly 12, and a fan blade 7 mounted on the rotating shaft 6. The drive motor 10 is connected to the rotating shaft 6 and the moving roller assembly 13 through a synchronous belt transmission mechanism 14.

[0025] The moving roller assembly 13 and the stationary roller assembly 12 are arranged side by side, with stationary roller assemblies 12 on both the left and right sides of the moving roller assembly 13. The moving roller assembly 13 and the stationary roller assembly 12 form an inclined corn cob processing chute, with the moving roller assembly 13 located in the middle of the chute. It should be noted that the stationary roller of the stationary roller assembly 12 is rotatably mounted on the frame 8. Because it does not rotate under active drive, it is called a stationary roller.

[0026] In addition, the frame 8 is welded from angle steel with an inclination angle of 30°. The 1.5kW drive motor 10 is connected to the 50mm diameter rotating shaft 6 and the roller shaft of the moving roller assembly 13 through the synchronous belt transmission mechanism 14. Three fan blades 7 are welded on the rotating shaft 6.

[0027] In application, corn cobs fall from the corn cob feed hopper 5 onto the moving roller assembly 13, that is, into the aforementioned inclined trough. The moving roller rotates, causing the corn cobs to roll downwards and rub against the stationary roller to peel off the outer skin. The peeled corn cobs roll from the lower end of the inclined trough to the corn cob outlet guide plate 2 and are discharged.

[0028] During the corn cob peeling process, the drive motor 10 synchronously drives the rotating shaft 6 and the moving roller to rotate, and then the fan blade 7 rotates to generate airflow, which discharges the corn husk residue that falls below the moving roller assembly 13 and the stationary roller assembly 12 from the side.

[0029] In practice, you can also choose to first cut off the head and tail of the corn cob with the husk on, and then use this device to peel it.

[0030] In one optional embodiment of this utility model, such as Figure 5 As shown, the synchronous belt drive mechanism 14 includes a first synchronous pulley, a second synchronous pulley, a third synchronous pulley, and a synchronous belt that drives the three synchronous pulleys together; the first synchronous pulley is mounted on the motor shaft of the drive motor 10, the second synchronous pulley is mounted on the rotating shaft 6; the third synchronous pulley is mounted on a wheel axle that is rotatably fitted to the frame 8, and the wheel axle is driven by the gear transmission group 15 to the roller shaft end of the moving roller assembly 13.

[0031] In one optional embodiment of this utility model, such as Figure 4 and Figure 5 As shown, the frame 8 is equipped with a corn husk discharge guide plate 11 located directly below the stationary roller assembly 12 and the moving roller assembly 13 and inclined to the side, and the rotating shaft 6 is located diagonally above the upper end of the corn husk discharge guide plate 11.

[0032] The shed corn husks fall from the gap between the stationary and moving rollers onto the inclined corn husk discharge guide plate 11, which then guides them out laterally. The fan blade 7 of the rotating shaft 6 is located obliquely above the upper part of the guide plate, and the airflow blows the remaining husks towards the lower side of the guide plate, accelerating their discharge.

[0033] In an optional embodiment of this utility model, the support legs at the lower ends of the frame 8 supporting the stationary roller assembly 12 and the moving roller assembly 13 are provided with adjustable lifting legs 9.

[0034] The tilt angle of the stationary / moving rollers can be changed by adjusting the lifting feet 9 of the support legs (such as threaded adjustment or hydraulic rods). The tilt angle can be adjusted according to the size of the corn cob or the peeling efficiency requirements to optimize friction and sliding speed.

[0035] In an optional embodiment of this invention, the frame 8 is further equipped with a first protective shell 1 encapsulating the drive motor 10, the rotating shaft 6, and the fan blade 7; a second protective shell 3 partially encapsulating the stationary roller assembly 12 and the moving roller assembly 13; and a third protective shell 4 encapsulating the synchronous belt drive mechanism 14. The second protective shell 3 is detachably connected to the frame 8, and both the first protective shell 1 and the third protective shell 4 are detachably connected to the second protective shell 3. The protective shells are detachably connected by snaps or bolts, facilitating separate maintenance. The design of the protective shells prevents personnel from contacting moving parts, reducing the risk of workplace injuries, and the encapsulation also reduces noise and debris splashing, improving the working environment.

[0036] In an optional embodiment of this utility model, the corn cob feed hopper 5 and the corn cob outlet guide plate 2 are detachably connected to the second protective shell 3.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
