[0002] During the corncob processing, workers often need to use corncob screening devices to screen corncobs of different particle sizes. Figure 1 As shown, it is composed of a screening body and a bottom screen. The problem with this technical solution is that most of the existing corn cob screening devices are not equipped with blocking protection components. The corn cobs are easily splashed out of the equipment during the vibration of the screening device, and the impurity dust mixed in the corn cobs is easily blown up during the vibration, thereby affecting the on-site environment and the staff, making it inconvenient to use. Utility Model Content

[0003] The purpose of the utility model is to solve the following problems existing in the prior art: most of the existing corn cob screening devices are not provided with blocking protection components, and the corn cobs are easily splashed out of the equipment during the vibration of the screening device, and the impurity dust mixed in the corn cobs is also easily blown up during the vibration, thereby affecting the on-site environment and the staff, and it is inconvenient to use.

[0004] In order to solve the problems existing in the prior art, the utility model provides a corn cob screening device, including a screening body and a bottom screen, the bottom of the screening body is provided with a bottom screen, the top of the screening body is provided with a protective cover, the two ends of the top of the protective cover are respectively provided with a first fan and a second fan, and the inner top of the protective cover is provided with a heating assembly.

[0005] Furthermore, the first fan is a blowing type drying fan, and the second fan is a suction type dust removal fan. After the first fan is started, the air blown out through the air outlet contacts with the heat to form a hot air circulation in the screening body to perform drying and dehumidification work, and the second fan generates suction to suck out the debris, dust and impurities raised during the corncob screening process through the dust removal port to perform dust removal and chip removal work.

[0006] Furthermore, a dust removal port is provided at the inner top of the protective cover, the input end of the second fan is connected to the dust removal port through a dust removal pipe, and a dust exhaust pipe is provided at the output end of the second fan. The second fan generates suction force to suck out the debris, dust and impurities raised during the corncob screening process through the dust removal port and discharge them to a designated location through the dust exhaust pipe.

[0007] Furthermore, an air outlet is provided at the inner top of the protective cover, and the output end of the first fan is connected to the air outlet through an air duct. After the heating component is started, heat is generated. After the first fan is started, the wind blown out through the air outlet contacts the heat to form hot air circulation in the screening body, thereby drying and dehumidifying the screening body and the corn cob.

[0008] Furthermore, the two sides of the bottom of the protective cover are connected to the screening body through spring assemblies. The screening body and the protective cover are connected through the spring assembly, and the protective cover has a shock-absorbing and buffering effect. Compared with the direct fixed connection method, the spring assembly connection can reduce the vibration load of the screening body without affecting its normal vibration screening work.

[0009] Furthermore, the protective cover is made of a transparent material, which makes it convenient for the staff to view the screening work in the screening body through the protective cover.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] During the screening process of the utility model, the protective cover is designed to block and intercept corn cobs splashed by vibration, thereby preventing corn cobs from splashing out of the equipment. After the heating component is started, heat is generated. After the first fan is started, the wind blown out through the air outlet contacts the heat to form hot air circulation in the screening body, thereby drying and dehumidifying the screening body and corn cobs, thereby preventing the corn cobs from clumping and having poor fluidity in a humid state, which makes it inconvenient to screen. After the second fan is started, suction is generated to suck out the debris, dust and impurities raised in the corn cob screening process through the dust removal port, and discharge them to a designated location through the dust exhaust pipe, thereby preventing the debris and impurities from mixing into the corn cobs to affect their quality, and preventing the raised dust and debris from affecting the on-site environment and staff, thereby increasing the practicality of the device.
