[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes a support frame 1 and a furnace body 2; the support frame 1 is fixedly set on the ground, and the bottom end of the furnace body 2 is screwed onto the support frame 1 using a plane bearing;

[0030] It also includes:

[0031] The fixed frame 3 is set on the front side of the support frame 1. The reducer 4 is fixedly set on the fixed frame 3. The reducer 4 is connected to an external power supply. The fixed frame 3 plays a positioning role, which makes it easy to fix the reducer 4 in a suitable position.

[0032] Gear 5 is fixedly mounted on the output end of reducer 4. Gear ring 6 is fixedly sleeved on the outer ring wall of furnace body 2. Gear 5 meshes with the tooth groove on gear ring 6. Through the cooperation of reducer 4 and gear 5, gear 5 drives gear ring 6 to rotate, thereby driving furnace body 2 to rotate.

[0033] The movable frame 7 consists of two movable frames 7, which are movably arranged on the left and right sides of the fixed frame 3 respectively. Two lead screws 8 are screwed to the left and right sides of the fixed frame 3 respectively using shaft seats, and one side of each movable frame 7 is threaded onto the lead screw 8. The position of the movable frame 7 is controlled by the lead screw 8.

[0034] Guide rod 9, there are two guide rods 9, which are fixedly installed on the left and right sides of the fixed frame 3 respectively, and the guide rod 9 is located below the lead screw 8. The other side of the moving frame 7 is movably sleeved on the guide rod 9, which restricts the movement direction of the moving frame 7, so that the moving frame 7 can only move along the direction of the guide rod 9.

[0035] The limiting plate 10 consists of two plates, which are respectively screwed onto the rear end of the moving frame 7 using a spring-loaded rotating shaft. The ends of the limiting plates 10 are inserted into the toothed grooves on the toothed ring 6. The ends of the limiting plates 10 are engaged with the toothed grooves to restrict the rotation direction of the furnace body 2 and prevent the furnace body 2 from rotating, which would affect the service life of the reducer 4. The sides of the two limiting plates 10 are provided with reinforcing rods 20, and the ends of the limiting plates 10 are provided with wear-resistant layers 21 to improve the quality of the limiting plates 10. The moving frame 7 is composed of two connecting frames 22 connected by bolts, and the connection between the two connecting frames 22 is provided with a reinforcing frame 23 by bolts to facilitate the disassembly of the two connecting frames 22 for replacement or repair of the limiting plates 10.

[0036] Two baffles 11 are fixedly mounted on the movable frame 7, and the baffles 11 are engaged with the limiting plate 10 to restrict the rotation direction of the limiting plate 10.

[0037] The bottom of the mounting bracket 3 is provided with a cooling component 12, which includes:

[0038] A heat pipe 13 is movably wound around the outer wall of the reducer 4, and the end of the heat pipe 13 is connected to an external cold water source. The condensate is circulated on the outer wall of the reducer 4 through the heat pipe 13, thereby quickly cooling the temperature of the reducer 4. Several heat dissipation plates 17 are fixed on the outer wall of the reducer 4, and the heat pipe 13 is in contact with the heat dissipation plates 17. The heat dissipation plates 17 increase the contact area between the reducer 4 and the outside world, thereby improving the cooling efficiency.

[0039] The air duct 14 is fixedly installed on the fixed frame 3, and the air outlet of the air duct 14 is located below the reducer 4. The air duct 14 is connected to an external fan. The air duct 14 facilitates the blowing of strong air onto the reducer 4 to accelerate the cooling of the reducer 4.

[0040] The heat insulation plate 15 is fixedly installed on the fixing frame 3. The heat insulation plate 15 is located between the furnace body 2 and the reducer 4. The heat insulation plate 15 is used to block the heat of the furnace body 2 from being directly transferred to the reducer 4.

[0041] Temperature sensor 16 is fixedly mounted on the fixed frame 3. Temperature sensor 16 is electrically connected to the external water pump and fan control to facilitate the detection of the ambient temperature around the reducer 4. When the temperature exceeds the movement range, the water pump and fan will automatically start.

[0042] An air induced ring 18 is fixedly fitted on the outer ring wall of the furnace body 2. Several fan blades 19 are set on the air induced ring 18, and the air induced ring 18 is located above the toothed ring 6. When the furnace body 2 rotates, it drives the air induced ring 18 to rotate, which facilitates the circulation of air around the furnace body 2 and prevents the temperature around the furnace body 2 from rising rapidly.

[0043] When using this utility model, the operator starts the reducer 4, which drives the gear 5 to rotate. The gear 5 drives the toothed ring 6 to rotate, and the toothed ring 6 drives the furnace body 2 to rotate counterclockwise. Since the end of the limiting plate 10 is stuck in the toothed groove of the toothed ring 6, and the rotation direction of the limiting plate 10 is restricted by the baffle 11, the rotation direction of the furnace body 2 is restricted, so that the furnace body 2 can only rotate counterclockwise, avoiding the furnace body 2 from rotating back and damaging the reducer 4. The furnace body 2 drives the induced draft ring 18 to rotate, and the induced draft ring 18 drives the air around the furnace body 2 to circulate through the fan blades 19, thereby reducing the rate at which the temperature around the furnace body 2 rises. When the temperature around the furnace body 2 reaches a certain range, the external water pump and fan are started through the temperature sensor 16, so that the condensate circulates in the heat pipe 13. Combined with the effect of the heat sink 17, the cooling effect of the reducer 4 is improved. At the same time, the air duct 14 blows strong air onto the reducer 4, thereby quickly reducing the temperature of the reducer 4.

[0044] Compared with the prior art, the beneficial effects of this utility model are:

[0045] 1. The position of the moving frame 7 is controlled by the lead screw 8, so that the end of the limiting plate 10 abuts against the tooth groove on the toothed ring 6. Combined with the limiting effect of the baffle 11, the rotation direction of the furnace body 2 is restricted, so as to prevent the furnace body 2 from rotating and damaging the reducer 4.

[0046] 2. A cooling component 12 is installed to improve the cooling effect on the reducer 4 through water cooling and air cooling, so as to avoid high temperature affecting the performance of the reducer 4;

[0047] 3. An air induced ring 18 is set up. The air induced ring 18, together with the fan blades 19, accelerates the air flow around the furnace body 2, which facilitates the rapid dissipation of heat from the surrounding area, thereby reducing the impact of the high temperature of the furnace body 2 on the environment.

[0048] 4. Set up connecting frame 22 to split the moving frame 7 into two connecting frames 22, which facilitates the replacement or repair of the limit plate 10.

[0049] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
