Description

Corn cob screening and classifying machine

technical field

The utility model relates to a corn cob grading device.

Background technique:

There are different sizes of corn cobs. In the production and operation, it is necessary to sort corn cobs of different sizes. One is to classify them according to the length and size of the corn cobs, so as to increase the orderliness and commerciality of the products, such as quick-freezing processing and vacuum packaging processing. Screening and grading must be carried out; the second is screening and grading according to the use of corn cobs. Large corn cobs are used for quick-freezing processing or vacuum packaging because of their good ear shape and are directly marketed for sale; small corn cobs lack kernels and are relatively bald. There are many, the grains are tender, and the appearance is relatively poor. These corn cobs can be screened out for shoveling and then further processed into corn milk (pulp, liquid, juice, etc.) to improve the utilization rate of raw materials and increase benefits; the current method is Using manual sorting, the workload is heavy and the work efficiency is low.

Contents of the invention

The purpose of the utility model is to provide a corn cob screening and classifying machine with reasonable structure and high work efficiency.

The technical solution of the utility model is:

A corn cob screening and grading machine is characterized in that it includes a frame, on which a drum for the entrance and exit of corn cobs is installed, and corn cob screening holes are arranged on the wall of the drum, and along the length direction of the drum, the corn cob screening holes are divided into small It is divided into different areas at most, and the corn cob guide plate connected with the frame is arranged in the drum; the corn cob screening hole is rectangular, and the length direction of the rectangle is consistent with the length direction of the drum.

The drum includes an inner wall, an outer wall is arranged outside the inner wall, and the corn cob screening holes on the inner and outer walls are superimposed and have partially staggered positions.

The outer wall and the inner wall are relatively movable.

The utility model has reasonable structure, high work efficiency and saves a lot of manpower.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a structural diagram of an embodiment of the utility model.

Detailed ways

A corn cob screening and grading machine, comprising a frame 1, a drum 2 with a corn cob inlet and outlet is installed on the frame, a corn cob screening hole 3 is arranged on the wall of the drum, and along the length direction of the drum, the corn cob screening holes range from small to small. It is divided into different areas, and the corn cob guide plate 4 connected with the frame is arranged in the drum; the corn cob screening hole is rectangular, and the length direction of the rectangle is consistent with the length direction of the drum.

The drum includes an inner wall 5, an outer wall 6 is arranged outside the inner wall, and the corn cob screening holes on the inner and outer walls are superimposed and have partially staggered positions. The outer wall and the inner wall are relatively movable.

There are also outer wall fixing nuts 7, sliding grooves 8 for installing the fixing nuts among the figure, and the outer wall and the inner wall are in a relatively movable form, and by moving relatively, the corn cobs stuck in the corn cob screening holes can be taken out. Also have front and rear roller 9,10 among the figure.
