A stirring rod 13 is fixedly installed on the top, a circular column 14 is fixedly installed on the bottom of the stirring rod 13, a stirring blade 15 is fixedly installed on the outer wall of the circular column 14, a circular groove 17 is provided on the top of the kettle cover 4, a feeding port 16 is provided on the inner wall of the circular groove 17, a support column 18 is provided on the inner wall of the circular groove 17, a connecting plate 19 and a spring 24 are slidably sleeved on the outer wall of the support column 18, a pressing plate 20 is installed on the outer wall of the connecting plate 19, a feeding cover 21 is fixedly installed on the bottom of the pressing plate 20, a feeding port 22 is provided at the bottom of the kettle cover 4, and a discharge port 23 is provided at the bottom of the kettle body 1.

[0022] In the above structure, a heat insulation board is provided on the top of the heating tank 5 to prevent the staff from being scalded during work. The kettle cover 4 is in a rounded shape, which allows the staff to better place the material box when adding materials, saving working time. By connecting one end of the support plate 8 to the circular motor 12 and the other end to the kettle cover 4, the circular motor 12 can be fixed, so that the circular motor 12 remains stable during work.

[0023] In a preferred embodiment, the base 9 is fixedly connected to the perforated cone 10 , the outer wall of the screw 11 is sleeved with the inner wall of the base 9 , and the anti-slip pad 3 is made of rubber.

[0024] In the above structure, the base 9 increases the contact area with the kettle cover 4, making the perforated cone 10 more stable. When the circular motor 12 is operating, it can effectively avoid shaking. By installing the screw 11 on the inner wall of the base 9, the screw 11 can be fixed. The rubber can increase the friction of the ground, which can effectively solve the problem of the kettle body 1 moving during operation and affecting normal work.

[0025] In a preferred embodiment, there are four heating tanks 5 and eight electric heating tubes 6, and the eight electric heating tubes 6 are evenly distributed on the inner walls of the four heating tanks 5. The outer walls of the electric heating tubes 6 are made of stainless steel. The diameter of the feeding cover 21 is smaller than the diameter of the feeding port 22. The diameter of the feeding cover 21 is consistent with the diameter of the feeding port 16, and the cross-section of the feeding cover 21 is conical.

[0026] In the above structure, by setting up multiple electric heating tubes 6, the heating time can be reduced and the heating efficiency can be improved. The stainless steel material has high thermal conductivity and corrosion resistance, which can increase the heating speed of the electric heating tube 6. By pressing the pressing plate 20 downward, since the diameter of the feeding port 16 is smaller than the diameter of the discharge port 22, the material can fall into the kettle body 1 through the gap. By setting the outer wall of the feeding cover 21 as an inclined surface, the material can be quickly transported to the discharge port 22, avoiding the accumulation of material on the feeding cover 21.

[0027] In a preferred embodiment, the spring 24 is made of carbon steel, and the height of the support column 18 is consistent with the opening height of the circular groove 17 .

[0028] In the above structure, due to the high hardness of carbon steel, the spring 24 can be durable and reliable. The support column 18 is consistent in height with the circular groove 17, which can limit and fix the support column 18, thereby preventing the feeding cover 21 from being separated from the feeding port 16 when the spring 24 is reset.

[0029] In a preferred embodiment, the electric heating tube 6 and the circular motor 12 are both electrically connected to the controller 7 , and the number of the stirring blades 15 is six.

[0030] In the above structure, by making the controller 7 transmit a signal and the electric heating tube 6 receive the signal, the electric heating tube 6 can heat the air and transfer the heat to the inner wall of the kettle body 1, thereby heating the material in the kettle body 1. By setting a plurality of stirring blades 15, the stirring speed can be accelerated to avoid uneven stirring of the material or the presence of large particles of material.

[0031] In a preferred embodiment, one end of the spring 24 is connected to the bottom of the connecting plate 19 , and the other end of the spring 24 is connected to the bottom of the circular groove 17 .

[0032] In the above structure, by pressing the pressing plate 20 downward, the spring 24 is deformed so that the feeding cover 21 is located on the inner wall of the feeding port 22. At this time, feeding can be carried out. After the feeding is completed, the pressing plate 20 is released. Under the rebound action of the spring 24, the outer wall of the feeding cover 21 can be kept level with the top of the feeding port 16, so that the kettle cover 4 remains closed.

[0033] Working principle: when using this equipment, the staff only needs to press the pressing plate 20 downward to compress the spring 24, and the material can smoothly enter the kettle body 1 through the inclined surface of the feeding cover 21. After the entire feeding work is completed, the staff releases the pressing plate 20. At this time, there is no external force restraint. The outer wall of the feeding cover 21 can be level with the top of the feeding port 16 under the action of the spring 24 rebounding, so that the kettle cover 4 is in a closed state, which can effectively prevent the internal material from splashing out. During work, when it is necessary to heat the material, the controller 7 transmits a signal and the electric heating tube 6 receives the signal, so that the electric heating tube 6 on the inner wall of the heating tank 5 can be operated. At this time, the electric heating tube 6 will release heat, and the temperature of the outer wall of the kettle body 1 will increase. At this time, the heat will be transferred to the inner wall through the outer wall of the kettle body 1, and then the internal material can be heated. In addition, the electric heating tube 6 in a specific area of ​​the kettle body 1 can be heated separately, and the electric heating tube 6 in other areas does not need to work, which not only saves heat but also improves the efficiency of local material heating.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
