DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 6 As shown, the utility model provides a hot air rotary furnace with adjustable air outlet angle, comprising a furnace body 1 and a rotary frame 4 rotatably arranged in the furnace body 1. The rotary frame 4 is an existing mature technology. The rotary frame 4 is driven by a motor installed at the bottom of the furnace body 1 to rotate so as to achieve comprehensive heating and drying of moon cakes. The rotating axis of the rotary frame 4 extends to the top of the furnace body 1 and is fixedly connected to a chassis 5. A positioning shaft 6 is fixedly connected to the chassis 5. A first gear 72 is sleeved on the positioning shaft 6, so that the first gear 72 can be sleeved on the positioning shaft 6 and supported by the chassis 5, thereby ensuring the stability of the first gear 72. When the first gear 72 is not needed, it is only necessary to pull the first gear 72 out of the positioning shaft 6. A circular array of hot air blowers 3 are installed on the surface of the furnace body 1. The air outlet end of each hot air blower 3 is connected to a U-shaped tube 31. Both ends of each U-shaped tube 31 are connected to an air inlet pipe 32. Each air inlet One end of the tube 32 extends into the furnace body 1 and is connected to an exhaust hose 33. The exhaust hose 33 has a deformable effect at one end of the air inlet pipe 32 to ensure the adjustment of the air outlet angle of the exhaust hose 33. The hot air is transported to the two air inlet pipes 32 through the U-shaped tube 31 by the hot air blower 3 and finally discharged through the exhaust hose 33, so as to dry and heat the interior of the furnace body 1 more comprehensively. An adjustment mechanism for adjusting the angle of each group of exhaust hoses 33 is provided in the furnace body 1, and the adjustment mechanism is used in conjunction with the first gear 72. When the rotating frame 4 rotates, it also drives the chassis 5, the positioning shaft 6 and the first gear 72 to rotate together, further driving the operation of the adjustment, thereby realizing the angle adjustment of each exhaust hose 33. The machinery, parts and equipment in this device all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0024] like Figure 1 As shown, a positioning frame 21 is fixedly connected to the outer side of the top of the furnace body 1, and a protective cover 22 is provided on the inner wall of the positioning frame 21. Through the arrangement of the positioning frame 21 and the protective cover 22, the rotating parts on the top of the furnace body 1 can be shielded to prevent people's clothes from being rolled into them, thereby protecting people and ensuring the normal operation of the device.

[0025] like Figure 2 , Figure 3 , Figure 6As shown, the adjustment mechanism includes a rotating rod 73 rotatably connected to the top of the furnace body 1 and extending into the furnace body 1, and a guide rod 74 fixedly connected to the furnace body 1. The top of the rotating rod 73 is fixedly connected to a second gear 71 meshing with the first gear 72. The surface of the rotating rod 73 is lifted and provided with a toggle assembly for driving the two exhaust hoses 33 to swing. The toggle assembly includes two reciprocating threads 77 opened on the surface of the rotating rod 73. The two reciprocating threads 77 are both threadedly sleeved with lifting plates 75, and the lifting plates 75 are sleeved on the surface of the guide rod 74. The sides of the two lifting plates 75 are fixedly connected with toggle rods 76, and the exhaust hose 33 is located in the middle of the toggle rods 76. Under the setting of the above structure, the positioning shaft 6 can be manually rotated to make the first gear 72 drive each second gear 71 to rotate, and further make each lifting plate 75 rise and fall on the rotating rod 73 and the guide rod 74, so that the toggle rod 76 The movable rod 76 will drive the exhaust hose 33 to swing, so that the angle of each exhaust hose 33 can be adjusted. The operation is more convenient and there is no need to rotate more parts. When there is no need to adjust the air outlet angle of the exhaust hose 33, it is only necessary to remove the first gear 72 so that the rotating frame 4 will not drive the second gear 71 to rotate during normal operation, so that the adjusted exhaust hose 33 can stably discharge air. When it is necessary to control the exhaust hose 33 to swing up and down reciprocatingly to discharge air, it is only necessary to sleeve the first gear 72 on the positioning shaft 6, and then use the slow rotation of the rotating frame 4 to drive the first gear 72 to rotate, and drive each second gear 71 to rotate together, so that each toggle rod 76 finally drives the corresponding exhaust hose 33 to swing back and forth, thereby improving the drying efficiency of the moon cakes in the rotating frame 4 and making the device more practical.

[0026] like Figure 1 As shown, a plurality of doors are arranged on the surface of the furnace body 1. A person can open each door to put the moon cakes in the rotating rack 4, and the operation is more convenient.

[0027] like Figure 6 As shown, each exhaust hose 33 is fixedly connected to a spring 34 on the upper and lower surfaces, and one end of the spring 34 is fixedly connected to the side of the air inlet pipe 32. The arrangement of the spring 34 not only ensures the stability of the exhaust hose 33, but also drives the corresponding spring 34 to deform when the exhaust hose 33 is swung by the pushing of the toggle rod 76. When the exhaust hose 33 is not in contact with the toggle rod 76, the exhaust hose 33 can be restored to a horizontal state.

[0028] The working principle and use process of the utility model: when it is necessary to adjust the outlet angle of each exhaust hose 33, it is only necessary to manually rotate the positioning shaft 6 to make the first gear 72 drive each second gear 71 to rotate, and further make each lifting plate 75 rise and fall on the rotating rod 73 and the guide rod 74, then the toggle rod 76 will push the exhaust hose 33 to swing, so as to achieve the angle adjustment of each exhaust hose 33, and the operation is more convenient, without rotating more parts, when it is not necessary to adjust the outlet angle of the exhaust hose 33, it is only necessary to remove the first gear 72, so that the rotating frame 4 During normal operation, the second gear 71 will not be driven to rotate, so that the adjusted exhaust hose 33 can stably discharge air. When it is necessary to control the exhaust hose 33 to swing up and down to discharge air, it is only necessary to sleeve the first gear 72 on the positioning shaft 6, and then use the slow rotation of the rotating frame 4 to drive the first gear 72 to rotate, and drive each second gear 71 to rotate together, so that each toggle rod 76 can push the corresponding exhaust hose 33 to swing back and forth, thereby improving the drying efficiency of the moon cakes in the rotating frame 4 and making the device more practical.
