Abstract

The invention discloses a lotus seedpod threshing device which comprises a hopper, a threshing roller, a threshing cylinder, a rotary screen, a rack, a small belt pulley, a motor, a triangular belt, a large belt pulley, a collecting box and a fan. In the working process, lotus seedpods enter the threshing cylinder through round holes in the lower portion of the hopper, the fixed threshing bars distributed on the threshing cylinder and the movable threshing bars distributed on the threshing roller hit and stir the lotus seedpods together, so that lotus seeds are separated from honeycomb-shaped holes of the lotus seedpods, and the separated lotus seeds fall into the collecting box through small holes of the rotary screen. Smashed lotus seedpod chippings fall down from small holes of the rotary screen and are blown down to the ground by the fan, and finally mechanical threshing of the lotus seedpod is achieved. The lotus seedpod threshing and separating device is novel and simple in structure, lotus seedpod threshing and separating work can be completed at a time, the lotus seedpod threshing production efficiency can be greatly improved, and the lotus seedpod threshing production cost can be reduced.

Description

Technical Field

[0001] The invention relates to the technical field of agricultural product processing machinery in agricultural machinery, and in particular to a lotus pod threshing device suitable for mechanical threshing of lotus pods. Background Art

[0002] Lotus pods, also known as lotus pods, are inverted cone-shaped spongy receptacles buried in the pistil of lotus flowers. The surface of the receptacle has many scattered honeycomb-like holes, which gradually swell after fertilization and are called lotus pods. Each hole contains a small nut, which is a lotus seed. Lotus seed meat has extremely high nutritional value and is a high-end nourishing food that everyone loves.

[0003] It is a technical problem to remove lotus seeds from lotus pods, which is currently mainly done manually. In the prior art, the lotus pod threshing device has a complex structure and high power consumption. In order to promote the development of the lotus seed industry, it is necessary to design a small and practical lotus pod threshing device. Summary of the invention

[0004] The invention aims to provide a lotus pod threshing device which can complete the lotus pod threshing and separation work at one time, so as to improve the lotus pod threshing production efficiency and reduce the lotus pod threshing production cost.

[0005] The present invention is achieved through the following technical solutions:

[0006] It includes a hopper 1, a threshing roller 2, a threshing cylinder 3, a rotary screen 4, a frame 5, a small pulley 6, a motor 7, a V-belt 8, a large pulley 9, a collecting box 10, and a fan 11. When working, the lotus pod enters the threshing cylinder from the circular hole below the hopper, and the fixed threshing rods distributed on the threshing cylinder and the dynamic threshing rods distributed on the threshing rollers hit and stir the lotus pod together, so that the lotus seeds are separated from the honeycomb holes of the lotus pod, and the separated lotus seeds fall into the collecting box from the small holes of the rotary screen, and the broken lotus pod debris falls from the small holes of the rotary screen and is blown to the ground by the fan, and finally the mechanical threshing of the lotus pod is realized.

[0007] Furthermore, the threshing roller 2 is connected to the large pulley 9 via a key at the bottom, and the threshing roller 2 is provided with several layers of movable threshing rods 201 in a circular array in each layer.

[0008] The threshing cylinder 3 is welded on the frame 5, and the inner wall of the threshing cylinder 3 is distributed with several layers of fixed threshing rods 301 in an annular array in each layer.

[0009] The movable threshing rod 201 and the fixed threshing rod 301 are conical in shape, and the front end diameter thereof is slightly larger than the size of lotus seeds, so that the movable threshing rod 201 and the fixed threshing rod 301 can separate the lotus seeds from the honeycomb holes of the lotus pod when hitting and stirring the lotus pod without cutting the lotus seeds.

[0010] The gap between the rotary screen 4 and the inner wall of the threshing cylinder 3 is 4 mm to ensure that the rotary screen can rotate stably; a number of small circular holes are distributed on the rotary screen, and the diameter of the small circular holes is slightly larger than the maximum diameter of the lotus seeds to ensure that the separated lotus seeds can fall into the collection box 10.

[0011] The wind speed of the fan 11 can be adjusted so that the wind force can blow away the fallen lotus pod debris but cannot blow away the fallen lotus seeds, causing the lotus seeds to fall into the collection box 10.

[0012] The working principle of the present invention is as follows: a lotus pod threshing device is composed of a hopper, a threshing roller, a threshing cylinder, a rotary screen, a frame, a small pulley, a motor, a V-belt, a large pulley, a collecting box, and a fan. When working, the lotus pod enters the threshing cylinder from the circular hole below the hopper, and the fixed threshing rods distributed on the threshing cylinder and the dynamic threshing rods distributed on the threshing rollers hit and stir the lotus pod together, so that the lotus seeds are separated from the honeycomb holes of the lotus pod, and the separated lotus seeds fall into the collecting box from the small holes of the rotary screen, and the broken lotus pod debris falls from the small holes of the rotary screen and is blown to the ground by the fan, and finally the mechanical threshing of the lotus pod is realized.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The invention has a small and simple structure and is more suitable for use by families and small vendors.

[0015] The threshing rod designed by the invention will not cut the lotus seeds into pieces, thus ensuring that the structure of the lotus seeds after threshing is intact. BRIEF DESCRIPTION OF THE DRAWINGS
