[0028] Through the above device, first, the soaking mechanism is pretreated, the walnuts to be stripped are put into the soaking tank 2, the soaking time is set in advance, the connection between the walnut skin and the kernel is loosened, and convenience is provided for subsequent stripping. After soaking, the soaking tank 2 is rotated through the lifting rod 3 and the rotating shaft 4 at both ends of the bottom, the inclination angle is adjusted, the soaked walnuts are moved to the discharge end, and preparation is made for transfer.

[0029] As Figure 7As shown, A in the figure is the first position of the transfer tank 7, and B is the second position of the transfer tank. After the transmission mechanism is started, the transfer tank 7 is initially in the first position matched with the discharge end of the soaking tank 2 to receive the soaked walnuts. Subsequently, the second motor 12 drives the screw rod 13 to rotate, and the connecting block (26) connected with the second guide rod 6 through threaded transmission is slid along the second guide rod 6, thereby driving the transfer tank 7 to move along the second guide rod 6. At the same time, the first motor 8 drives the worm 9 to rotate, and the worm 9 meshes with the turbine 10 and the coaxial first gear 11 to rotate. The first gear 11 meshes with the teeth on the first guide rod 5 to assist the stable movement of the transfer tank 7. When the transfer tank 7 moves to the top of the second guide rod 6, in one embodiment, the screw rod 13 is divided into a threaded section and a non-threaded section. When the transfer tank 7 moves to the top of the second guide rod 6, the connecting block 26 reaches the non-threaded section of the screw rod 13, the screw rod 13 idles, and the connecting block 26 no longer slides. In one embodiment, the second guide rod 6 is provided with a touch button or an infrared sensor. When the transfer tank 7 moves to the top of the second guide rod 6, the touch button or the infrared sensor is triggered to control the second motor 12 to stop rotating. The transfer tank 7 continues to slide along the first guide rod 5 at one end of the first guide rod 5, and the other side of the transfer tank 7 rotates around the connecting block 26 until it reaches the second position matched with the water gun undressing mechanism inlet end, thereby completing the automatic transfer of walnuts without manual intervention.

[0030] The high-pressure water gun undresses, and the transfer tank 7 sends the walnuts from the inlet 17 into the barrel 14. The water tank 16 continuously supplies high-pressure water flow to the high-pressure nozzle 15 inside the barrel 14. The high-pressure water jetted out of the high-pressure nozzle 15 strongly impacts the walnut shell, and the softened shell is broken and peeled off by the impact force of the water flow. The undressed walnuts move to the discharge end of the barrel 14 by the water flow or their own gravity and fall into the first end of the conveyor belt 18. Optionally, in one embodiment, the barrel 14 is arranged obliquely.

[0031] The conveyor belt 18 transports the undressed walnuts to the cleaning mechanism area. The cleaning nozzle 21 is connected with the water tank 16 and continuously sprays low-pressure cleaning water flow to perform secondary washing on the shell debris and impurities remaining on the surface of the walnuts, thereby ensuring the cleanliness of the walnut kernel surface. Finally, the cleaned walnuts are output by the conveyor belt 18, and the entire undressing and cleaning process is completed.

[0032] Optionally, the water gun undressing mechanism and the cleaning mechanism are provided with a recycling water tank 19 at the lower end. The barrel 14 is provided with a third motor 22, the output end of the third motor 22 is provided with a filter plate 20, the filter plate 20 is slidably connected with the barrel 14, and the conveyor belt 18 is a steel wire mesh conveyor belt.

[0033] Through the above device, after the walnuts enter the barrel 14, the water tank 16 supplies high-pressure water flow to the high-pressure spray head 15, and the shell is impacted to realize the stripping. In this process, the third motor 22 is started, and the filter plate 20 connected with the output end of the third motor 22 is driven to slide in the barrel 14: on the one hand, the filter plate 20 can play an auxiliary guiding role on the walnuts, avoiding the accumulation of walnuts in the barrel, and ensuring that each walnut can be fully impacted by the high-pressure water flow; on the other hand, the filter screen structure of the filter plate 20 can separate the waste water generated in the stripping process from the walnuts, and the waste water flows downward through the gap of the filter plate. At the same time, the recovery water tank 19 at the lower end of the barrel 14 receives the waste water falling from the filter plate 20, and preliminarily realizes the solid-liquid separation, reducing the impurity load in the subsequent cleaning stage. The stripped walnuts are moved to the discharge end of the barrel 14 under the action of the pushing of the filter plate 20 and the gravity of the walnuts, and finally fall into the first end of the steel wire mesh conveyor belt 18.

[0034] Optionally, the rack 1 is provided with a limiting hinge support 27, the rack 1 is hinged with a connecting frame 23 through the limiting hinge support 27, the connecting frame 23 is provided with a fourth motor 24, and the output end of the fourth motor 24 is fixedly connected with a stirring rod 25.

[0035] Through the above device, the limiting hinge support 27 limits the rotation angle of the connecting frame 23, the first rotation angle is a working angle, and the second rotation angle is a transfer angle; when the pretreatment of the soaking mechanism is performed, the connecting frame 23 rotates to the working angle around the limiting hinge support 27, so that the stirring rod 25 can stir the materials in the soaking mechanism, the pretreatment speed of the soaking mechanism can be accelerated, the walnuts can be preliminarily stripped, and the stripping efficiency is increased; when the pretreatment of the soaking mechanism is completed, the connecting frame 23 is rotated to the second rotation angle, so that the stirring rod 25 is completely separated from the soaking tank 2, the soaking tank 2 can be rotated under the action of the lifting rod 3 and the rotating shaft 4, and the materials in the soaking tank 2 are transferred to the transfer tank 7.

[0036] Optionally, the stirring rod 25 is made of an elastic material.

The preferred embodiments do not describe all the details, and the utility model is not limited to the specific implementation. Obviously, according to the content of the specification, many modifications and changes can be made.
