Detailed Description
The invention is further described below with reference to the accompanying drawings:
as shown in figures 1-4, the emptying prevention device for the ore pass disclosed by the invention is arranged above an ore discharge opening at the bottom end of the ore pass 1 and comprises a blocking plate 4, one side of the blocking plate 4 is hinged with the bottom end of the ore pass 1, a rebounding mechanism is arranged above the blocking plate 4 at the hinged side of the bottom end of the ore pass 1, one end of the rebounding mechanism is hinged with the blocking plate 4, and the other end of the rebounding mechanism is hinged with the wall of the ore pass 1; a supporting mechanism is arranged below the blocking plate 4, one end of the supporting mechanism is hinged with the lower surface of the opening of the blocking plate 4, and the other end of the supporting mechanism is hinged with the bottom surface of the ore drawing opening 6 of the chute 1.
In this embodiment:
rebound mechanism top is equipped with guard plate 2 to guard plate 2 sets up to 4 opening parts slopes of closure plate, and the material of guard plate 2 is elastic rubber, can prevent effectively that rebound mechanism from receiving the impact force of ore 8 and damaging.
The rebound mechanism comprises two design schemes, which are specifically described as follows:
the first rebound mechanism is an extension spring 3, the extension spring 3 with a proper elastic coefficient is selected, the structure is simple, and the quantity of the tension springs can be selected as required.
And the rebounding mechanism comprises a first pneumatic cylinder 10 and a weight sensor, the weight sensor is arranged on the upper surface of the blocking plate 4, the weight sensor transmits a signal to the controller through a wire, and the controller controls the first pneumatic cylinder 10 to act. A weight sensor with a large load is selected, the impact force of the ore 8 cannot exceed the maximum load of the weight sensor, the weight of the ore 8 above the blocking plate 4 when the blocking plate 4 is closed can be set according to needs, and when the set weight is reached, the controller receives signals to control the piston rod of the first pneumatic cylinder 10 to retract, so that the blocking plate 4 is closed; when the new ore 8 passes through the shaft 1 again, the weight sensor transmits a signal to the controller, and the controller receives the signal to control the piston rod of the first pneumatic cylinder 10 to extend out, so that the blocking plate 4 is opened.
The support mechanism comprises two design schemes, which are specifically described as follows:
supporting mechanism scheme one, supporting mechanism include telescopic link 11, and the lower surface of the interior pole top of telescopic link 11 and 4 openings of closure plate is articulated, and the outer pole of telescopic link 11 is articulated with the bottom surface of 1 ore drawing mouth 6 of drop shaft to 11 periphery covers of telescopic link are equipped with compression spring 5. The compression spring 5 plays a role in jacking and closing the blocking plate 4, and the telescopic rod 11 plays a role in guiding and supporting.
And the supporting mechanism comprises a second pneumatic cylinder 9 and a weight sensor, the weight sensor is arranged on the upper surface of the blocking plate 4, the weight sensor transmits a signal to the controller through a wire, and the controller controls the second pneumatic cylinder 9 to act. A weight sensor with a large load is selected, the impact force of the ore 8 cannot exceed the maximum load of the weight sensor, and when the weight of the ore 8 is reduced to a set value, a piston rod of a second pneumatic cylinder 9 extends out and is closed by matching with the blocking plate 4; when a new ore 8 passes through the shaft 1, the piston rod of the second pneumatic cylinder 9 retracts and is matched with the blocking plate 4 to be opened.
The thickness of closure plate 4 is reduced to the opposite side by articulating one side with 1 bottom of drop shaft gradually, and closure plate 4 articulated one side thickness is big, and support intensity is big, and opening part thickness is little, and light in weight helps closure plate 4 easily to realize the switching.
The baffle 7 is additionally arranged at the bottom end of the wall of the chute 1 at the opening of the blocking plate 4, and the top end of the baffle 7 is hinged with the bottom end of the wall of the chute 1. In the closing process of the blocking plate 4, the baffle 7 can properly reduce the sliding speed of the ore 8, and the blocking plate 4 can be closed smoothly.
Resilience mechanism itself has resilience force, and when 8 weight in ore were greater than resilience force, the opening side of closure plate 4 was opened, and 8 rollovers of ore, and closure plate 4 will close when opposite. When the ore blocking device is used, when the weight of the ore 8 in the chute 1 is insufficient, the rebounding mechanism controls the blocking plate 4 to close, the ore 8 is stopped to be discharged, and the ore 8 above the blocking plate 4 can play a role in preventing the ore rock from secondarily damaging the bottom of the chute 1; when ore 8 enters ore drawing again, the ore 8 weight of the ore pass 1 is sufficient, the opening side of the blocking plate 4 is opened, and the ore 8 passes through. Supporting mechanism of closure plate 4 below plays the supporting role to the ore 8 of closure plate 4 and closure plate 4 top on the one hand when stopping ore drawing, prevents that rebound mechanism from damaging because of bearing heavily for a long time, and on the other hand can prevent that rebound mechanism from appearing the dead point and influencing rebound of rebound mechanism to the 1 ore 8 of drop shaft that prevents better is emptied, effectively prevents that ore deposit rock can carry out the secondary to 1 bottom of drop shaft and destroys.
