The sampling mechanism comprises a pawl 9, a ratchet 10 and a sampling part;
the ratchet 10 is sleeved on the main shaft 3, the near end of the pawl 9 is movably connected to the bearing seat mounting fixing frame 8, the upper end of the pawl 9 is in lap joint with the ratchet 10, and the sampling part is connected to the main shaft 3 through a pin shaft.
The sampling part comprises a swing shaft 11, a balancing weight 12, a rubber base plate 13 and a coal hanging plate 14;
the balancing weight 12 is fixed on the rear surface of the swing shaft 11 through a bolt; the rubber backing plate 13 is arranged on the front surface of the swing shaft 11, and the coal hanging plate 14 is arranged on the front surface of the rubber backing plate 13 and is fixedly connected with the swing shaft 11 through bolts.
The side surface of the mounting rack 1 is provided with a collecting box 15, and the lower surface of the collecting box 15 is provided with a discharge hole.
The lower surface of the mounting frame 1 is provided with a plurality of support legs 16.
The lower surface of the mounting frame 1 is provided with a conveying belt 17.
The upper surface of the mounting frame 1 is provided with a protective cover 18.
And a motor protective shell 19 is arranged on the upper surface of the motor mounting fixing frame 4.
The working principle is as follows:
the cam 6 and the ratchet wheel 10 are fixed at the shaft end of the main shaft 3 through key connection, and the main shaft 3 is installed on the bearing seat installation fixing frame 8 through the bearing seat installation fixing frame 8. The middle of the main shaft 3 is milled into a flat square, and the sampling part is connected to the main shaft 3 through a pin. The crankshaft 5 is installed on the speed reducing motor 2, the crankshaft 5 rotates to drive the cam 6 to rotate, then the main shaft 3 is driven to rotate, and the sampling part rotates accordingly. The sampling part moves to the highest point and then does pendulum motion by means of self inertia to collect coal into the collection box 15. The ratchet wheel 10 and the pawl 11 limit reverse rotation, so that the sampling part stops above the belt, and one-time sampling is completed. The running time and the interval of the speed reducing motor 2 are controlled by a control system, and the sampling period is controlled.
The power system is simple and reliable. The gear motor 2 is adopted, so that the intermediate link of transmission is omitted, the space is saved, and the weight is reduced.
The principle is novel. The sampling part is driven to the highest point from the stop position by the speed reducing motor 2, and the sampling is stopped by the ratchet 10 and the pawl 9 structure and is not stopped by the gravity and the inertia of the sampling part. The speed reducing motor in the sampling period works only in 1/4 hours, and the speed reducing motor runs in no-load mode in the rest of the time, so that the service life of the speed reducing motor 2 is greatly prolonged.
Is suitable for sampling various kinds of coal. The sampling panel is only replaced to adapt to various coal types, and the operation is simple and convenient. The panel of the sampler has one large end and one small end, and can realize sampling of two coal types without changing the panel by rotating 180 degrees, thereby having good applicability.
The sampling can be carried out at regular time through the control system, the sampling period is adjustable from 0s to 99h, different sampling requirements are met, and labor is saved.
The coal sample of collecting box 15 can be led to ground through the pipeline, and to non-ground belt sampling, the people can be saved and the sample is climbed, intensity of labour is reduced, and sampling and sample are easily carried out.
The protective cover 18 is adopted to form a closed structure, so that the belt can safely walk along the belt gallery.
And the later maintenance cost is low. All the structures mainly use mechanical parts, the reliability is high, no easily damaged parts exist, and the maintenance cost is very low.
The coal on the conveyer belt 17 is conveyed through the coal feeder, the coal quality is uniform, the granularity is not more than 100mm, the belt groove angle is not more than 35 degrees, and the sampling is most accurate.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
