The mechanical push rods device suitably increases and reduces according to the volume size of skip bucket, is uniformly distributed in skip bucket
Lower section, emphasis act on skip bucket and easily find the orientation blocked, and uniform force.
For the push rod by the evenly distributed combination of 16-25 root elongate cylinders, the active force for making to act on the outside of skip bucket is uniform, prevents
Only skip bucket is deformed because stress is concentrated.
When load coal skip bucket start unloading when, be distributed in skip bucket both sides several mechanical push rods devices be in wait for work shape
State, i.e., push rod is far from skip bucket；When finding that skip bucket blocks, worker opens motor switch, by motor through retarder band movable eccentric wheel
Mechanism kinematic, eccentric wheel uniform rotation, through connecting rod drive straight along fixed track box with sliding block push rod fixed together
Line moves, and on the outside of regular shocks skip bucket, when skip bucket outer wall vibrates, the cinder for being attached to skip bucket inner wall is made to take off
It falls, to play the role of block clearing；After stopping state solves, power supply can be closed, mechanical push rods device is made to reset；May be used also when unloading coal
Push rod movement speed is controlled, effective block clearing is reached by regulation motor rotating speed according to stopping state.
The utility model compared with prior art, has an advantageous effect in that：
1) a kind of mining skip bucket blockage-clearing device belongs to automatic block clearing device, compared to traditional artificial block clearing, have it is time saving,
Efficiently, the advantages such as safe and reliable, not only effectively increase the raising efficiency of coal mine, can more mitigate the labor intensity of worker, ensure
Personal safety；
2) apparatus structure is simple and convenient to operate, and later maintenance is also convenient, is widely portable to the mining dustpan of various models
Bucket, especially large-tonnage skip bucket；
3) mechanical push rods device is evenly distributed on the both sides of skip bucket, and emphasis is distributed in the middle lower section of skip bucket, because of these positions
Easy blockage phenomenon is set, when a jam does occur, eccentric mechanism movement is driven by motor, push rod linear movement is driven, has
The shock skip bucket outer wall of rule, plays the role of block clearing.Push rod makes skip bucket by 16~25 evenly distributed combinations of elongate cylinder simultaneously
Outside uniform force prevents skip bucket from being deformed because stress is concentrated.
