[0028] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0029] The utility model provides a heating cover of a bell-shaped electric heating furnace, comprising:

[0030] Electric heating furnace base 1;

[0031] The electric heating furnace base 1 can hold the products to be sintered, and at the same time, a support leg is fixedly installed on the lower end surface of the electric heating furnace base 1, which can support the electric heating furnace base 1 and keep it stable;

[0032] A heating cover 2 is provided on the upper end surface of the electric heating furnace base 1;

[0033] The heating cover 2 can cover the product to be sintered so that the product is in a sealed ring;

[0034] A partition 3 is arranged in the heating cover 2;

[0035] The side wall surface of the partition plate 3 is fixedly connected to the inner wall surface of the heating cover 2, so that the inner space of the heating cover 2 can be divided into two;

[0036] The rotating plate 4 is arranged below the partition plate 3;

[0037] A plurality of stirring rods 5 are arranged in a row on the lower end surface of the rotating plate 4;

[0038] The top end of the stirring rod 5 is fixedly connected to the lower end surface of the rotating plate 4 and can be relatively fixed;

[0039] A driving member 6 is provided on the inner upper end surface of the heating cover 2;

[0040] The driving member 6 is fixedly mounted on the inner upper end surface of the heating cover 2 and can be kept fixed;

[0041] The electric push rod 7 is fixedly connected to the output end of the driving member 6, and the telescopic end passes through the partition plate 3 and is fixedly connected to the upper end surface of the rotating plate 4;

[0042] The telescopic end of the electric push rod 7 is extended, which can drive the rotating plate 4 and the stirring rod 5 to move downward at the same time. At the same time, the driving member 6 is a motor, and the rotation of its output end can drive the electric push rod 7 to rotate, and at the same time make the rotating plate 4 and the stirring rod 5 rotate together, so that the stirring rod 5 can stir the sintered product.

[0043] Specifically, it also includes;

[0044] an annular groove 8 formed on the upper end surface of the rotating plate 4;

[0045] The annular block 9 is slidably mounted in the annular groove 8;

[0046] A limit rod 10, one end of which is fixedly connected to the upper end surface of the annular block 9, and the other end of which passes through the partition plate 3 and is fixedly mounted on the limit block;

[0047] When the rotating plate 4 moves downward, the annular block 9 can be driven to move simultaneously. At this time, the limiting rod 10 slides in the partition 3. The limiting rod 10 can limit the position of the annular block 9 to prevent it from rotating. At the same time, when the rotating plate 4 rotates, the annular block 9 slides in the annular groove 8, which can make the rotating plate 4 more stable when rotating.

[0048] An annular limiting groove 11 is formed in the rotating plate 4 and communicates with the annular groove 8;

[0049] The annular limiting block 12 is fixedly mounted on the outer wall surface of the annular block 9 and is slidably connected to the annular limiting groove 11;

[0050] Under the action of the annular limiting groove 11 and the annular limiting block 12 , the annular block 9 can be prevented from being separated from the annular groove 4 .

[0051] Specifically, a fixing ring 13 is provided around the outer side of the electric push rod 7, a connecting rod 14 is fixedly installed on the upper end surface of the fixing ring 13, and one end of the connecting rod 14 away from the fixing ring 13 is fixedly connected to the upper wall surface of the heating cover 2;

[0052] An annular slide groove 15 is formed on the inner wall surface of the fixed ring 13, and an annular slider 16 slidably connected to the annular slide groove 15 is fixedly installed on the outer surface of the electric push rod 7;

[0053] When the electric push rod 7 rotates, the annular slider 16 can be driven to slide in the annular slide groove 15, so that the electric push rod 7 can remain stable during the rotation.

[0054] Specifically, an annular cavity 17 is formed in the side wall of the heating cover 2, and a heat-insulating cotton 18 is arranged in the annular cavity 17;

[0055] The heat-insulating cotton 18 can play a role in heat preservation and prevent the temperature in the heating cover 2 from being lost.

[0056] Specifically, a heat dissipation port 19 is formed at the upper end of the side wall of the heating cover 2, and a dustproof net 20 is fixedly installed in the heat dissipation port 19;

[0057] The heat dissipation opening 19 can conveniently dissipate heat for the driving member 6 , and the dustproof net 20 can block external pollutants to prevent them from entering the heating cover 2 through the heat dissipation opening 19 and causing pollution to the driving member 6 and the electric push rod 7 .

[0058] Working principle: When sintering the product, the staff starts the electric push rod 7. The telescopic end of the electric push rod 7 extends to drive the rotating plate 4 and the stirring rod 5 to move downward at the same time, so that the stirring rod 5 contacts the product. When the rotating plate 4 moves, it can drive the annular block 9 and the limit rod 10 to move at the same time. The limit rod 10 can limit the position of the annular block 9 to prevent it from rotating. At this time, the staff drives the driving member 6, and the output end of the driving member 6 rotates to drive the electric push rod 7 to rotate. At this time, the rotation of the electric push rod 7 drives the rotating plate 4 and the stirring rod 5 to rotate at the same time, so that the stirring rod 5 stirs the sintered product, so that the product can be sintered evenly, improving the sintering quality. At the same time, under the action of the annular block 9 and the annular groove 8, the rotating plate 4 can rotate more stably, bringing convenience to people.
