Description

Technical Field

[0001] The invention relates to the field of screening machines, and in particular to a sweet potato screening machine with an automatic aperture adjustment function. Background Art

[0002] A screening machine is a device used to screen agricultural products. It usually classifies them by size, weight or color. It can be applied to different agricultural products and is usually divided into drum type, vibrating type or linear screening or eccentric screening.

[0003] When adjusting the existing screening machine, it is usually necessary to dismantle and reinstall the screening holes, which is not convenient for the staff to make quick adjustments and affects the work efficiency. Summary of the invention

[0004] The purpose of the present invention is to solve the above defects and provide a sweet potato screening machine with automatic aperture adjustment function.

[0005] The objective of the present invention is achieved in the following manner: a sweet potato screening machine with an automatic aperture adjustment function comprises a frame and a screening component, the screening component is arranged in the middle of the frame, the screening component comprises a primary screen and a secondary screen, the primary screen and the secondary screen are both made of nylon cloth, the surfaces of the primary screen and the surfaces of the secondary screen are both distributed with screen holes of different apertures, the primary screen and the secondary screen are both arranged in the middle of the frame through a roller shaft, one side of the roller shaft is connected to a motor for providing power, the secondary screen is arranged below the primary screen, and vibrators are provided on both sides of the top of the primary screen and on both sides of the top of the secondary screen.

[0006] Furthermore, a flow outlet is provided on the outer side surface of the frame near the earphone screen, and a triangular block is provided in the middle of the flow outlet for easy pouring.

[0007] Furthermore, a diverter block is provided at the top of the frame near the primary screen, and the diverter block is used to provide a diverter and classification effect after screening.

[0008] Furthermore, a blocking block is provided between the primary screen and the secondary screen, and the blocking block is used to prevent the primary screen and the secondary screen from entering the gap.

[0009] The beneficial effects produced by the present invention are as follows: by distributing sieve holes with different apertures on the surface of the primary sieve and the secondary sieve, when adjusting the aperture, the staff can start the motor, the motor drives the roller to rotate, and the roller drives the primary sieve and the secondary sieve to rotate, and the required aperture is rotated and moved out, without the need for the staff to disassemble the screening holes, thereby improving work efficiency.

[0013] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0014] See also Figure 1 The invention discloses a sweet potato screening machine with automatic aperture adjustment function, comprising a frame 1 and a screening component, wherein the screening component is arranged in the middle of the frame 1, and the screening component comprises a primary screen 2 and a secondary screen 3, both of which are made of nylon cloth, and the surfaces of the primary screen 2 and the secondary screen 3 are both provided with screen holes 4 with different apertures, the primary screen 2 and the secondary screen 3 are both arranged in the middle of the frame 1 through a roller shaft 6, and a motor 7 for providing power is connected to one side of the roller shaft 6, the secondary screen 3 is arranged below the primary screen 2, and vibrators 5 are arranged on both sides of the top of the primary screen 2 and both sides of the top of the secondary screen 3.

[0015] A flow outlet 8 is provided on the outer side of the frame 1 near the earphone screen, a triangular block 9 is provided in the middle of the flow outlet 8 for easy pouring, a diverter block 10 is provided on the top of the frame 1 near the primary screen 2, and a blocking block 11 is provided between the primary screen 2 and the secondary screen 3.

[0016] After placing the sweet potatoes on the upper surface of the primary screen 2, turn on the vibrator 5, which will drive the primary screen 2 and the secondary screen 3 to vibrate, driving the sweet potatoes to be vibrated and screened. After screening, the sweet potatoes will be classified and flowed out through the outflow port 8 and the triangular block 9.
