Technical Field
[0001] The utility model relates to the technical field of tube chain machines, in particular to an automatic unloading device for a tube chain machine. Background Art
[0002] The pipe chain machine is a device that uses a chain as a traction tool to transport powdery materials, granular materials or block materials in a pipeline. The chain of the pipe chain machine is built into the pipeline, and a number of scraper plates are arranged at intervals on the chain. A space for material transportation is formed between two adjacent scraper plates. The pipeline is provided with a feeding node and a discharging node. Through the traction of the chain, the material can be transported from the feeding node to the discharging node.
[0003] The existing pipe chain machine also has the following shortcomings: when there are multiple discharge nodes on the pipeline, the discharge amount of each discharge node depends on the material conveying speed of the pipe chain machine and the size of the discharge port at the discharge node, and it is impossible to achieve flexible control of the discharge amount at different discharge nodes. For example, some discharge nodes need to be closed at certain times, some discharge nodes need to be closed at certain times, and some discharge nodes need to increase or decrease the discharge amount at certain times.
[0004] Therefore, it is necessary to develop an automatic unloading device for a tube chain machine that can flexibly control the discharge amount at different discharge nodes in response to the above problems. Utility Model Content

[0015] As a further improvement of the present invention, a short hopper is connected to the edge of the discharge control port of the discharge pipe to prevent material from overflowing when the discharge control port faces upward.
[0016] The automatic unloading device of the tube chain machine of the utility model is provided with three working states: closed unloading, static unloading and dynamic unloading.
[0017] Among them, when the automatic unloading device is set to the closed unloading working state, the unloading control port of the unloading pipe is always set upwards through the control of the servo motor.
[0018] Wherein, when the automatic unloading device is set to a static unloading working state, the unloading control port of the unloading pipe is always set at a certain angle relative to the up and down direction through the control of the servo motor.
[0019] Wherein, when the automatic unloading device is set to the dynamic unloading working state, the unloading tube is controlled by the servo motor to rotate around its own axis at a set speed, thereby realizing dynamic unloading.
[0020] By means of the frequency conversion control of the servo motor, the material feeding amount can be controlled more accurately.
