Description

TECHNICAL FIELD

[0001] The present disclosure relates to lotus seed processing equipment, in particular to an intelligent lotus seed processing all-in-one machine. BACKGROUND

[0002] Traditional lotus seed processing requires manual picking of lotus pods from the field, then separating the lotus seeds from the lotus pods, and then using a special blade to cut open and shell the shelled lotus seeds one by one. Since the lotus seeds are wrapped in a translucent outer skin, the outer skin is bitter and has no medicinal value, so the shelled lotus seeds need to be immersed in water and manually rubbed to remove the outer skin. This manual labor method is troublesome, labor-intensive, time-consuming, and inefficient, and cannot meet market demand.

[0003] With the development of society and the progress of technology, lotus seed crushing, shelling, peeling, and core passing processing equipment have emerged. Mechanization and automation are the inevitable development direction of lotus seed processing. However, existing lotus seed core passing equipment, lotus seed shelling equipment, and lotus seed peeling equipment are generally separate. During the conveying process, the lotus seeds are prone to deviation and misalignment. Color marker detectors are generally used to identify the head or tail end of the lotus seeds to determine the direction of the lotus seeds, and then the lotus seeds with incorrect direction are blown off by a blowing mechanism. Lotus seeds that are not completely shelled or peeled or are damaged are manually picked out. The lotus seed shelling generally uses a spring booster assembly. The movement of the booster plate causes the conveyor belt to press the shell plate to squeeze the lotus shell, thereby removing the cut shell from the conveyor belt. The structure is complex, inconvenient to operate, low in precision and efficiency, prone to missed picking and mistaken picking, and poor in stability and reliability, thereby affecting the quality and yield of lotus seed processing, high in cost, and unable to meet the increasing production demand.

[0044] The shelling device 8 comprises a first conveying belt 81, a shell cutting device 84 and a circular arc shell pressing assembly 85. The first conveying belt 81 is driven by an eighth driving mechanism 82. The eighth driving mechanism 82 can drive the first conveying belt 81 to convey the lotus seeds with shells by a motor, a transmission shaft, a transmission wheel and the like. The shell cutting device 84 and the shell pressing assembly 85 are sequentially matched with the first conveying belt 81. The shell cutting device 84 is used to cut the shells of the lotus seeds conveyed on the first conveying belt 81 in sequence. The shell pressing assembly 85 is used to make the cut shells fall off.

[0045] The shell pressing assembly 85 comprises a first shell pressing plate 851 and a first fixed support 852. The first shell pressing plate 851 is made of elastic material. The first fixed support 852 is fixed and used to support the first conveying belt 81. The first fixed support 852 corresponds to the first shell pressing plate 851. The first shell pressing plate 851 can form a first channel 801 with the first conveying belt 81. The shape, length and position of the first shell pressing plate 851 are determined according to specific conditions. The lotus seeds after shell cutting can be conveyed along the first channel 801. The cut shells can fall off under the extrusion of the first shell pressing plate 851.

[0046] In use, the eighth driving mechanism 82 drives the first conveying belt 81 to convey the lotus seeds with shells. When the lotus seeds with shells are conveyed to the position corresponding to the shell cutting device 84, the shell cutting device 84 cuts the shells of the lotus seeds in sequence. Then the lotus seeds after shell cutting are conveyed along the first channel 801. The first fixed support 852 supports the first conveying belt 81. The first shell pressing plate 851 extrudes the shells by relying on its elasticity. The force is stable. The soft first shell pressing plate 851 has a larger contact surface with the shells. The force is more comprehensive and uniform. The shells can fall off better. The lotus seeds after shell cutting are not damaged. The fallen shells are collected by the corresponding collecting box. The lotus seeds after shell cutting enter the first conveying device 7 in sequence. Thus, the automatic shelling of the lotus seeds is realized. The structure is simple, compact and stable. The precision, stability and reliability are high. The quality and efficiency of the lotus seed shelling are improved.

[0047] The first shell pressing plate 851 can be made of silica gel, super glue or elastic rubber. The first shell pressing plate 851 is made of silica gel.

The lotus seeds after shelling are sequentially conveyed through the arc-shaped channel 802 and the straight channel, thereby ensuring more comprehensive and complete shelling, better effect, and higher efficiency. For example, the rack 1 is provided with three first driving wheels 8521 cooperating with the first conveying belt 81. The three first driving wheels 8521 are arranged in a triangular shape with one on top and two on the bottom. The two first driving wheels 8521 on the bottom have substantially the same height.
