[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] A green onion peeling machine, such as Figure 1 and Figure 2 As shown, it includes a frame 1, on which is provided a peeling cavity 2 for placing green onions, and two blowing devices 3 are provided at the feeding end of the peeling cavity 2. The green onions are placed between the two blowing devices 3, and the green onions are inserted into the peeling cavity 2 from the feeding end. The two blowing devices 3 blow out high-pressure gas to blow off the outer skin of the green onions, and the discharge end of the peeling cavity 2 is connected to a waste channel 14, and a collecting bag is fixed at the rear of the waste channel through a collecting bag bracket 15, and the high-pressure gas blows the peeled outer skin from the waste channel 14 into the collecting bag.

[0027] The upper cover 11 of the peeling chamber 2 is rotatably connected to the frame 1 by means of a hinge. A driving cylinder 17 is vertically arranged on one side of the peeling chamber 2. A welding rod 18 is fixed on the top of the upper cover 11. The welding rod 18 is rotatably connected to the piston rod of the driving cylinder 17. When the piston rod of the driving cylinder 17 retracts downward, it drives the upper cover 11 to flip and open. When the piston rod extends upward, it drives the upper cover 11 to flip and close. The upper cover 11 is initially in an open state, mainly to facilitate the insertion of green onions. The upper cover 11 is then closed when blowing, and is opened again when the blowing stops.

[0028] like Figure 3 and Figure 4 As shown, the blowing ports of the two blowing devices 3 are inclined in opposite directions, and the peeling cavity 2 is in a "Y" shape, shrinking inward from the feeding end, so that the high-pressure gas is more concentrated on the green onion.

[0029] A positioning frame 10 for fixing the green onions is provided at the feed end of the peeling cavity 2. The positioning frame 10 is located between the two blowing devices 3. There is an arc-shaped groove on the positioning frame 10. The green onions can be snapped into the groove to achieve a positioning effect and increase stability during blowing. A proximity switch 12 is provided below the positioning frame 10. The proximity switch 12 is connected to the positioning frame 10 as a whole and is fixed to the end of the peeling cavity 2 by screws. When the green onions are placed in the positioning frame 10, the proximity switch 12 detects that an object is approaching, thereby controlling the blowing device 3 to blow air without manual opening. When working for a long time, it can effectively reduce the workload and increase work efficiency.

[0030] The blowing device 3 is connected to a tornado blowing assembly 4, which includes a blowing hose 401 and a limiting tube 402. The blowing hose 401 is connected to the air outlet of the blowing device 3, and the high-pressure gas of the blowing device 3 is blown out through the blowing hose 401. The limiting tube 402 covers the outside of the blowing hose 401, and there is a gap between the inner wall of the limiting tube 402 and the blowing hose 401. The limiting tube 402 is fixed on the blowing device 3, and a flare 5 is provided at one end of the limiting tube 402 away from the blowing device 3.

[0031] When the blowing device 3 blows out gas, the blowing hose 401 will swing due to its flexibility. After being restricted by the limiting tube 402, the blowing hose 401 will swing in a circle along the edge of the expansion opening 5 of the limiting tube 402, so that the blown gas can contact the green onion more evenly and the green onion skin can be peeled off more easily.

[0032] like Figures 3 to 5 As shown, a heating device 6 is provided on the frame 1, and the heating device 6 is used to heat the blowing hose 401. When the temperature is low in winter, the blowing hose 401 will harden and affect the swinging effect. Therefore, the heating device 6 is used to heat and soften the blowing hose 401 to ensure the normal use of the equipment.

[0033] The heating device 6 includes a heating chamber 601 fixed on a bracket, a heating coil 602 is arranged in the heating chamber 601, the air in the heating chamber 601 is heated by the heating coil 602, an air outlet 7 is opened on the side wall of the heating chamber 601, a blower 603 is also connected to the side wall of the heating chamber 601, the blower 603 blows air into the heating chamber 601, so that the hot air in the heating chamber 601 is blown out from the air outlet, the air outlet 7 is connected to a hot air pipe 604 extending to the bottom of the limiting pipe 402, and there are two air outlets 7, and the two hot air pipes 604 are respectively located under the two limiting pipes 402 for heating.

[0034] The heating device 6 also includes a control box 605 fixed on the heating chamber 601. The control box 605 is provided with a heating switch 8 and a potentiometer 9. The heating switch 8 controls the opening and closing of the heating device 6, and the potentiometer 9 can adjust the current size, thereby adjusting the temperature of the heating coil 602 according to demand.

[0035] Two mounting brackets 16 are fixed on the side wall of the feed end of the peeling chamber 2. A sliding hole is opened on the mounting bracket 16. The blowing device 3 is inserted into the sliding hole and fixed to the mounting bracket 16 by flange bolts. The hot air pipe 604 is inserted upward from the bottom of the sliding hole so that the outlet of the hot air pipe 604 is opposite to the limiting pipe 402.

[0036] The frame 1 is provided with a power switch 13 to control the opening and closing of the power of the entire device.

[0037] The working process of the utility model is as follows:

[0038] The staff holds the green onion and puts it into the peeling cavity 2, and the end of the green onion is clamped on the positioning frame 10. After the proximity switch 12 detects the green onion, the upper cover is closed and the blowing device 3 is turned on. The blowing hose 401 blows out high-pressure gas while swinging in a circle to blow off the green onion skin; when the temperature is lower in winter, the heating device 6 is turned on first, and the hot air pipe 604 blows out hot air to heat and soften the blowing hose 401, and then the peeling work is carried out.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
