Description

Technical Field

[0001] The invention relates to the technical field of shelling and fruit picking, and in particular to an intelligent water chestnut shelling and fruit picking device. Background Art

[0002] Water chestnut is the fruit of an aquatic plant, widely grown and deeply loved in many areas of my country. It has a unique shape, with a hard and irregular shell and edible flesh inside. In recent years, my country's agricultural technology has continued to develop, and the market for water chestnuts has reached tens of billions of yuan, but processing is still in its infancy.

[0003] Traditionally, the shelling and removal of water chestnuts mainly rely on manual operations. People use knives and other tools to cut the shells of water chestnuts one by one, and then take out the flesh inside. This manual processing method is not only inefficient, but also requires certain skills and strength during the cutting process. Improper operation can easily lead to hand injuries, posing a major safety hazard.

[0004] At present, the traditional method of peeling water chestnuts in households is mostly to use a kitchen knife and a small hammer or to break the water chestnut shell by hand, and then take out the water chestnut kernel. Since the water chestnut shell is hard, the water chestnut kernel is easily damaged during the processing, which makes it difficult to take out the water chestnut kernel in the shell, resulting in waste. The function of intelligent shelling and meat removal cannot be achieved well, and thus the problems of high labor intensity, low production efficiency, high labor cost and high water chestnut kernel damage rate cannot be solved well. In view of this, we propose an intelligent water chestnut shelling and fruit removal device. Summary of the invention

When the stepping hydraulic cylinder 412 is started, the push plate 413 pushes the water chestnuts to the bottom of the floating pressure plate 512, and then the push plate 413 is reset in the reverse direction.

On the other hand, a cutting blade 59 is fixedly installed on the outside of the cutting shaft 58, and two groups of cutting blades 59 are provided. A fixing block 510 is fixedly installed at the center of the top of the U-shaped frame 56, and a vertical rod 511 is slidably installed inside the fixing block 510. The lower surface of the top of the vertical rod 511 is in contact with the top of the fixing block 510, and a floating pressure plate 512 is fixedly installed at the bottom of the vertical rod 511.

One end of a return spring 610 is fixedly installed inside the rectangular groove 69, and the other end of the return spring 610 is fixedly installed on the slide bar 611. When the extrusion motor 64 is started, the eccentric arc plate 68 and the roller 66 are squeezed against each other, forcing the water chestnut shell to deform and rupture, thereby achieving the effect of separating the shell and the meat, and then the water chestnut can be better shelled and the fruit can be taken out. At the same time, when large-sized water chestnuts appear, the roller 66 applies a thrust to the eccentric arc plate 68 through the water chestnuts. When the thrust exceeds the critical deformation value of the return spring 610, the slide bar 611 slides in the rectangular groove 69, causing the return spring 610 to contract, and the gap between the roller 66 and the eccentric arc plate 68 is increased, thereby achieving the effect of adaptive water chestnut size.

A separation plate 75 is clamped on the inner side of the water tank 71, and the separation plate 75 is inclined. Furthermore, according to the characteristics of the water chestnut shell with low density and high buoyancy, and the water chestnut kernel with high starch content and high density, after falling into the clean water in the water tank 71, the water chestnut kernel sinks to the bottom of the water due to gravity, while the shell floats on the water surface due to buoyancy, thereby achieving the purpose of separating the water chestnut shell from the kernel. At the same time, the separation plate 75 is used to prevent the water chestnut shell and the kernel at the water surface of the water tank 71 from being mixed together again, thereby achieving the purpose of limiting the shell space in the water tank 71. When the bottom reduction motor 73 is started, the inclined conveyor belt 74 can better collect the water chestnut kernel and separate the shell, thereby solving the problems of low efficiency, high cost and low integrity rate of peeled kernels in manual water chestnut peeling.

After a preset time value, the horizontal reduction motor 49 is restarted to achieve the effect of step-by-step operation, thereby enabling the device to operate better.

[0030] Working principle: first, input the water chestnut body into the hopper 41, then when the feeding motor 42 is started, the feeding shaft 43 rotates, thereby causing the groove wheel 44 to rotate, so as to achieve the single water chestnut feeding and control the feeding speed by controlling the rotation speed of the groove wheel 44 in the hopper 41, and then the water chestnut falls into the conveyor belt 47 with baffles to ensure that each water chestnut enters each process separately, when the oblique reduction motor 46 is started, the conveyor belt 47 with baffles transports the water chestnut to the horizontal conveyor belt 410, and cooperates with the limiting baffle 81 in the auxiliary component 8 to better center and allow a single water chestnut to pass horizontally sideways, and finally transported to the top of the square plate 411 through the unloading chute plate 82, and intercepted by the baffle bar 83, when the stepping hydraulic cylinder 412 is started, the push plate 413 pushes the water chestnut to the floating Directly below the dynamic pressure plate 512, the push plate 413 is then reset in the opposite direction. When the stepping asynchronous motor 52 is started, the ball screw 53 is rotated, so that the threaded plate 54 can move up and down, thereby driving the U-shaped frame 56 to move synchronously. When the cutting reduction motor 57 is started, the cutting shaft 58 is rotated, so that the shells at both ends of the water chestnut can be cut off, so that the overall anti-extrusion property of the water chestnut is reduced. At the same time, when the U-shaped frame 56 moves downward, it will drive the fixed block 510, the vertical rod 511 and the floating pressure plate 512 to move downward synchronously close to the water chestnut, and at the same time, the spring 513 is pressed and compressed and deformed, so that the cutting process is more stable. After the water chestnut is cut, the stepping hydraulic cylinder 412 is started again, so that the push plate 413 continues to push the water chestnut forward to the inclined slot plate 61, and then falls into the eccentric arc plate 68 and roller 66, when the extrusion motor 64 is started, the eccentric arc plate 68 and roller 66 are squeezed against each other, forcing the water chestnut shell to deform and rupture, achieving the effect of separating the shell and the meat, and then the water chestnut shell can be better cut and the fruit can be taken out. At the same time, when a large-sized water chestnut appears, the roller 66 applies a thrust to the eccentric arc plate 68 through the water chestnut, so that when the thrust exceeds the critical deformation value of the reset spring 610, the slide bar 611 slides in the rectangular groove 69, so that the reset spring 610 contracts, and the gap between the roller 66 and the eccentric arc plate 68 increases, so as to achieve the effect of adaptive water chestnut size. Furthermore, according to the characteristics of the water chestnut shell with low density and high buoyancy, the water chestnut kernel with high starch content and high density, after falling into the cleaning water in the water tank 71, the water chestnut kernel is The water chestnut shells are forced to sink to the bottom of the water, while the shells float on the water surface due to buoyancy, thereby achieving the purpose of separating the water chestnut shells from the kernels. At the same time, the separation plate 75 is used to prevent the water chestnut shells and kernels at the water surface of the water tank 71 from being mixed together again, thereby achieving the purpose of limiting the shell space in the water tank 71. When the bottom reduction motor 73 is started, the inclined conveyor belt 74 can better collect the water chestnut kernels and separate the shells, thereby solving the problems of low efficiency, high cost and low completeness rate of peeled kernels in manual water chestnut peeling. Furthermore, when the water chestnuts pass through the infrared sensor 84, the horizontal reduction motor 49 is controlled to stop running, and the water chestnuts are continuously conveyed to the square plate 411 by inertia.
