Description

Technical Field

[0001] This utility model relates to the field of corn cleaning technology, specifically a corn cleaning device. Background Technology

[0002] Before processing, feed ingredients must be screened to remove impurities to prevent them from entering the feed processing equipment, damaging the equipment, and reducing feed quality. Corn is a common ingredient in piglet feed. During preparation, it's necessary to remove any corn kernels that are not of the correct size. A patent with publication number CN218554708U discloses an easy-to-install corn cleaning screen, including a base plate and a bottom plate. The screen works by pouring collected corn kernels into a trough, then starting a first motor to rotate a screw, which in turn moves a first pusher plate and a second pusher plate on the screw in opposite directions. This pushes the corn kernels from the trough through the discharge pipe into a box that moves left and right. By using the two screen plates to separate the corn kernels, a double-layer screening process is achieved, improving the screening efficiency. By setting up a mechanism that allows two screen plates to slide on a mounting bracket until they are removed from the housing, personnel can then remove impurities from the screen plates. After impurity removal, the two screen plates are then placed back into the housing via the mounting bracket. This makes installation and disassembly of the screen plates more convenient and quick, further improving the ease of use of the device. Although it is convenient for screening corn according to specifications, the screening process can easily cause corn husks to fly around, which can pollute the air. Therefore, a corn cleaning device is designed to facilitate the screening of corn kernels that meet the specifications and to facilitate the dry recycling of corn husks to avoid pollution, while also avoiding the waste of water resources caused by wet spraying.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, the present invention provides a corn cleaning device, which has the following beneficial effects:

[0013] This corn cleaning device uses a vibrating sieve mechanism to easily screen out substandard corn kernels. Simultaneously, the substandard kernels are collected by a flow collector and flow from the center to a receiving tray at the bottom. While screening, a dry corn husk recovery mechanism is activated. With the cooperation of the exhaust chamber and the husk suction hood, the corn husks screened by the vibrating sieve mechanism are pulled downwards, passing through the flow collector and then into the exhaust chamber. Negative pressure is then applied to the dry corn husk recovery mechanism for dry recovery. This corn cleaning device facilitates the separation of standard corn kernels and the dry recovery of corn husks, preventing pollution and avoiding the waste of water resources associated with wet spraying.

[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] Example:

[0022] Please see Figure 1-5 A corn cleaning device includes a vertical cylinder 2 that runs vertically through the center. A flow collecting hood 3 and a hull suction hood 4 are fixedly connected vertically in the middle of the vertical cylinder 2. A suction annular cavity is formed between the flow collecting hood 3 and the hull suction hood 4 and the inner wall of the vertical cylinder 2. A vibrating sieve is detachably placed at the top of the vertical cylinder 2. A receiving tray 8 that can be withdrawn from the bottom is provided at the bottom of the vertical cylinder 2. The device also includes a corn hull dry recycling mechanism located outside the vertical cylinder 2 and connected to the suction annular cavity.

[0023] Specifically, the vibrating sieving mechanism includes a bracket 6 that can be clamped at the top of the vertical cylinder 2. A filter screen cylinder 5 that can extend into the top of the vertical cylinder 2 is fixedly installed at the bottom of the bracket 6. A vibration motor 7 is fixedly installed on the bracket 6. Furthermore, the vibration motor 7 is configured as two sets and is located on both sides of the bracket 6. The filter screen cylinder 5 is extended into the vertical cylinder 2 and then clamped at the bottom of the vertical cylinder 2 by the bracket 6. Then, the sieved corn kernels are poured into the filter screen cylinder 5, and then the vibration motor 7 is started, which can drive the filter screen cylinder 5 to vibrate, thereby screening out the corn kernels and corn husks that do not meet the specifications, so that the filter screen cylinder 5 finally retains the cleaned and qualified corn kernels.

[0024] Specifically, the dry corn husk recycling mechanism includes a filter cylinder 12 and an exhaust fan 13. An exhaust ring net 11, which communicates with the exhaust ring cavity, is fixedly connected to one side of the top of the filter cylinder 12. A filter husk mesh cylinder 14 and a counterweight cover 15 can be sequentially arranged and held on the top of the filter cylinder 12. A through groove is provided on the filter husk mesh cylinder 14, which communicates with the exhaust ring net 11 and the filter cylinder 12. The input end of the exhaust fan 13 is connected to the bottom of the filter cylinder 12. Activating the exhaust fan 13 facilitates the creation of a negative pressure in the exhaust ring cavity through the filter cylinder 12 and the exhaust ring net 11, thereby drawing the corn husks into the filter cylinder 12 and leaving them in the filter husk mesh cylinder 14. When recycling is required, the counterweight cover 15 can be removed from the top, and then the filter husk mesh cylinder 14 can be pulled out from the filter cylinder 12 to clean out the corn husks for recycling.

[0025] Specifically, the bottom of the vertical cylinder 2 is fixedly connected to the base frame 1 by multiple support rods, and a material unloading gap is formed between the bottom of the vertical cylinder 2 and the base frame 1. The top of the base frame 1 is vertically fixedly installed with a drive cylinder 9, and the top output end of the drive cylinder 9 is fixedly installed with a tray 10 that can engage with the receiving tray 8. The drive cylinder 9 can easily drive the tray 10 to lift and lower, so that the receiving tray 8 placed on the tray 10 can be lifted and lowered, so that the receiving tray 8 that is sealed and inserted into the bottom of the vertical cylinder 2 can be removed, and the non-compliant corn kernels can be cleaned out separately.

[0026] Specifically, both the filter cartridge 12 and the exhaust fan 13 are mounted on the base frame 1 to improve overall stability.
