Problems solved by technology

The traditional winnowing machine cannot fully disperse the corn kernels, causing part of the corn silk and stem and leaf fragments to be directly pressed by the corn kernels. Under the action of the wind, they cannot be separated, resulting in poor winnowing effect and difficult to meet the needs of modern processing.

Embodiment 1

[0026] see Figure 1~3 , a kind of air selection and screening device for corn kernels based on rolling and splitting technology, comprising a tower body 1, a screen 2 is provided at the bottom of the inner cavity of the table body 1, and the screen 2 is arranged obliquely, and the screen 2 The inner cavity of tower body 1 is divided into winnowing chamber 3 and wind chamber 4, and described winnowing chamber 3 is arranged on the top of wind chamber 4, and the top of the left end of winnowing chamber 3 connects feeding pipe 5 through, and the top of winnowing chamber 3 The left wall of the inner cavity is provided with a deflector 6 matched with the feed pipe 5, and the deflector 6 is arranged obliquely. A grading roller 7, the grading roller 7 is connected to the inner wall of the winnowing chamber 3 through a rotating shaft 8, and one end of the rotating shaft 8 runs through the tower body 1 and is fixedly connected to the motor outside the machine (not shown in the figure)....

Embodiment 2

[0028] This embodiment is a further elaboration on the basis of Embodiment 1. The feed pipe 5 is a V-shaped structure, and one side end of the incoming pipe 5 is fixedly connected to the tower body 1 through a connecting rod 10. By setting the connecting rod 10 , used to improve the stability of the feeding pipe 5; the top of the feeding pipe 5 is connected to the feeding hopper 9, and the corn grains are added through the feeding hopper 9, and enter the tower body 1 through the feeding pipe 5.

[0029] The bottom end of the right side of the inner cavity of the air separation chamber 3 is connected to the first discharge pipe 11, and the first discharge pipe 11 corresponds to the lowest end of the screen 2, and the corn kernels are blown in the wind separation chamber 3. After being selected, it falls on the sieve 2 and slides down along the sieve 2. The large-grained corn kernels slide down with the sieve 2, and finally are discharged through the first discharge pipe 11, and ...

Embodiment 3

[0032] This embodiment is a further elaboration on the basis of Embodiment 1. The bottom edge of the tower body 1 is evenly provided with a number of legs 20, and a fan 19 is arranged on one of the legs 20, and the fan 19 passes through The air pipe 18 is connected with the air blowing device 16, and provides sufficient wind for the air blowing device 16 through the fan 19, so as to ensure the continuity of winnowing work and improve the processing efficiency.

[0033] The middle part of the bottom end of the wind chamber 4 is connected to the second discharge pipe 22, and the bottom wall of the inner cavity of the wind chamber 4 is provided with a diversion bucket 21 matched with the second discharge pipe 22. The second discharge pipe The bottom end of 22 is sheathed with sealing cover 23, and the small particle corn grain that sieve cloth 2 screens enters the second discharge pipe 22 and discharges under the effect of diversion funnel 21.

[0034] The top of the winnowing ch...

Abstract

The invention discloses a corn winnowing screening device based on a rolling decentralizing technology. The corn winnowing screening device comprises a tower body, a screening mesh is arranged at thebottom of an inner cavity of the tower body, and the screening mesh is obliquely arranged and separates the tower body into a winnowing cavity and a wind cavity; and the winnowing cavity is arranged on the upper part of the wind cavity, a feeding pipe is connected to the top of the left side end of the winnowing cavity in a penetrating mode, a deflector which is matched with the feeding pipe is arranged on the left wall of an inner cavity of the winnowing cavity, and a corn screening roller which is matched with the deflector is arranged on the left side of the inner cavity of the winnowing cavity. According to the corn winnowing screening device based on the rolling decentralizing technology, an out-device motor drives the corn screening roller to rotate clockwise at a high speed, the corn is added through a feeding hopper and passes through the feeding pipe and the deflector and directly drops to the corn screening roller which rotates at the high speed, the corn is collided with thecorn screening roller and scattered and decentralized, the corn is scattered to the bottom of the winnowing cavity, wind power is used for screening corn, corn stigmas and chips of stems and leaves,and the winnowing quality is improved; and the corn can be screened through the screening mesh, sizes of granules are classified, the corn is enabled to be evener, and subsequent production is facilitated.

Description

technical field [0001] The invention relates to the field of corn kernel processing equipment, in particular to a corn kernel winnowing and screening device based on rolling, beating and spreading technology. Background technique [0002] Maize is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop. It is also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. [0003] The history of corn cultivation in my country is about 470 years. However, due to its high yield, good quality and strong adaptability, the cultivated area has developed rapidly. At present, my country's sown area is about 300 million mu, second only to rice and wheat, and ranks third among food crops. second only to the United States in the world. my country has also accumulated rich experience in the cultivation technology of corn. Sowing: The natural conditions of...
