Device for changing rotating speed based on gravity variations to prevent feeding machine from being blocked

Abstract

The invention relates to the technical field of mechanical equipment, and discloses a device for changing the rotating speed based on gravity variations to prevent a feeding machine from being blocked. The device comprises a supporting plate. Due to the cooperative use of a threaded stud, a first sliding block, a small rotating wheel and a transverse rod, the conveying speed is increased, a blocked feeding pipe is automatically dredged, the phenomenon that a machine breaks down due to the fact that the machine cannot run normally is avoided, and the service life period of the device is prolonged. Due to the cooperative use of a baffle, a connecting rod and a connecting block, when a bearing plate descends to drive the baffle to be closed, the blocked feeding pipe can be automatically closed, and conveying burdens of the feeding pipe are relieved. Due to cooperative use of the baffle and the connecting rod, consequent reactions are in linkage, the linkage of the whole device is improved, and operation is easier and more convenient. Dredging can be performed by means of gravity variations of the bearing plate, and no other external energy needs to be supplied, so that the whole device is more intelligent and more environmentally friendly, and the using cost is lower.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a device for changing the rotating speed based on the change of gravity so as to prevent the feeder from clogging. Background technique [0002] The feeder is also called the feeder. The feeder is widely used in different industries such as metallurgy, coal mines, metals, and building materials. Regularly and continuously conveying to the receiving device, such as continuous and uniform feeding for crushing machinery in the sand making production line, is still an indispensable mechanical device in the actual production process. [0003] The feeder is generally installed under the hopper during use. It is a machine that can continuously and evenly control the loose flow and can be used for extremely short-distance transportation. The feeder can be divided into electromagnetic vibration feeder, rod feeder and Screw feeder, in which the screw feeder generally achieves...

AI Technical Summary

Problems solved by technology

[0003] The feeder is generally installed under the hopper during use. It is a machine that can continuously and evenly control the loose flow and can be used for extremely short-distance transportation. The feeder can be divided into electromagnetic vibration feeder, rod feeder and Screw feeder, in which the screw feeder generally achieves the purpose of quantitative feeding by controlling the constant rotation speed of the screw. However, there may be blockage during the feeding process, and the traditional feeder cannot do this. It is judged that the material is still fed evenly, which will increase the conveying burden of the device, making it more clogged, and it is impossible to unblock. At this time, it is generally necessary to manually operate the unblocking. It increases the labor burden of the staff and reduces the work efficiency, and if the staff does not find out and solve it in time, the machine is prone to failure and increases the production cost

[0004] In order to solve the above problems, the inventor proposed a device that changes the rotation speed based on gravity changes to prevent the feeder from clogging. It has the advantage of automatically unclogging when the feeder exceeds the maximum limit, and solves the problem that the traditional feeder cannot Automatically unblocks the problem of blockage, ensuring that the staff does not need to be guarded by the staff when using the device, which improves work efficiency while reducing the occurrence of mechanical failures and improving the service life of the machine
