[0002] In industrial production, the cone silo is generally used as a buffer silo and a feeding device to ensure the continuity of industrial production. In practical applications, the traditional cone silo feeding device has the following defects when in use: high-density large-particle materials can slide from the feeding port by their own gravity, but the powder with small specific gravity is easy to be hardened and adhered to the wall of the silo, and is not easy to slide down, especially when the powder with a large water content is fed, it is easy to be hardened and block the feeding port, which seriously hinders the continuity of feeding, and the operating personnel need to carry out the unblocking operation for a long time, which reduces the operating efficiency. At the same time, since the existing material cylinder is installed on the cone feeding device, it is easy to shake, which can easily cause the equipment to tilt or the material to spill. SUMMARY

[0003] 3. To solve the above technical problems, one of the technical solutions adopted by the utility model is: a holding mechanism, which is used to realize the holding action of the material cylinder after the material cylinder is installed at the discharge port of the cone feeding device, and avoid the shaking of the material cylinder after installation. The mechanism comprises:

[0004] A support wire pipe 1 is installed in the discharge port;

[0005] A cylinder mounting shell 2 is located in the discharge port; the mounting shell is supported and installed in the discharge port through the support wire pipe 1;

[0006] An upper flexible positioning air bag 3 and a lower flexible positioning air bag 4 are used to flexibly hold the material cylinder at the discharge port of the cone feeding device after the upper flexible positioning air bag 3 and the lower flexible positioning air bag 4 are inflated;

[0007] The upper flexible positioning air bag 3 and the lower flexible positioning air bag 4 are both installed on the cylinder mounting shell 2.

[0008] Further, the upper end of the upper flexible positioning air bag 3 is installed on the telescopic end of the cylinder mounting shell 2 through an upper pressing block 5;

[0009] The lower end is installed in the middle part of the cylinder mounting shell 2 through an upper pressing ring 6.

[0010] Further, the upper end of the lower flexible positioning air bag 4 is installed in the middle part of the cylinder mounting shell 2 through a lower pressing ring 7;

[0011] The lower end is installed at the bottom of the cylinder mounting shell 2 through a lower pressing ring 8.

[0012] Furthermore, the mechanism further comprises: at least two air ports 9 for respectively inflating the corresponding upper flexible positioning airbag 3 and lower flexible positioning airbag 4 .

[0013] Another technical solution adopted by the present invention is: a conical feeding device, which includes the above-mentioned clamping mechanism.

[0014] The advantages and positive effects of the utility model are as follows: after the barrel is installed on the conical feeding device, the air port is opened and the corresponding upper flexible positioning airbag 3 and the lower flexible positioning airbag 4 are inflated, so that the upper flexible positioning airbag 3 fits the outer wall of the barrel; the lower flexible positioning airbag 4 fits the inner wall of the discharge port, thereby achieving a clamping effect and avoiding shaking, which may cause the equipment to tilt or the material to spill.
