In this embodiment, the limiting frame 20 has a channel 21, the discharge hole 11 of the bin 10 is disposed over against the limiting frame 20, and the material in the bin 10 can drop downwards into the car hopper 200 through the channel of the limiting frame 20, so that the feeding of the car hopper 200 by the blanking device is realized. That is, when the blanking device of the present embodiment is operated, the material in the bin 10 can enter the hopper 200 through the channel 21 of the limiting frame 20 under the action of gravity. It should be noted that the storage bin 10 is provided with a bin gate (not shown) controlled by a motor (not shown), and when the motor controls the bin gate to open the discharge port 11, the material in the storage bin 10 can fall down through the discharge port 11 under the action of gravity, otherwise, when the motor controls the bin gate to close the discharge port 11, the material in the storage bin 10 does not fall down, that is, the storage bin 10 is closed.
Wherein, limit frame 20 can be asway connected with two adjustable fender 22, two adjustable fender 22 sets up symmetrically limit frame 20 goes up two outsides of passageway 21, limit frame 20 is every adjustable fender 22 is last to correspond respectively and is provided with signal trigger 23, just adjustable fender 22 is in can trigger after swinging certain angle on limit frame 20 signal trigger 23, feed bin 10 can receive the signal that signal trigger 23 sent and control feed bin 10 closes.
Specifically, the limiting frame 20 is provided with two connecting members 23 downward, the two connecting members 23 are arranged in one-to-one correspondence with the two movable baffles 22, and each movable baffle 22 is connected with the corresponding connecting member 23 in a hinged manner, so that the movable baffles 22 are rotatably connected with the limiting frame 20. It should be noted that the connecting member 23 may be configured as a rod-like structure or a plate-like structure according to the use requirement.
Further, the position of the connecting member 23 relative to the limiting frame 20 is adjustable, so that the position of the movable baffle 22 arranged on the limiting frame 20 is adjustable, and the distance between the two movable baffles 22 arranged on the limiting frame 20 is adjustable. So that the blanking device can be suitable for quantitative discharge of trucks with hoppers 200 of different widths. It should be noted that the position between the connecting member 23 and the limiting frame 20 is adjustable, specifically, a sliding groove (not shown) is formed in the limiting frame 20, and limiting notches (not shown) are formed at intervals on the length edge of the sliding groove, and the connecting member 23 can move along the sliding groove, so that when the connecting member 23 is clamped into the limiting notches, the limiting fixation of the connecting member 23 on the limiting frame 20 is realized; or the position of the limiting frame 20 for fixing the connecting piece 23 is set as a movable structure.
In this embodiment, the signal trigger is limit switch 24, limit switch 24 is fixed on connecting piece 23, and works as adjustable fender 22 is in during the certain angle of outside swing on connecting piece 23, adjustable fender 22 can touch limit switch 24, limit switch 24 can send the signal for feed bin 10, feed bin 10 can receive during the signal that limit switch 24 sent, motor start control on the feed bin 10 the door is right the discharge gate 11 of feed bin 10 carries out the shutoff, and then realizes closing of this feed bin 10.
It is understood that the signal trigger is not limited to be set as a limit switch, and those skilled in the art can set the signal trigger as other sensors such as a proximity switch according to the use requirement.
It can be understood that when the material drops into the car hopper 200 from the discharge port 11 of the bin 10, the material in the car hopper 200 continuously piles up and forms a pile along with the material continuously dropping into the car hopper 200, and the formed pile continuously rises and pushes the two movable baffles 22 on the limiting frame 20, so that the two movable baffles 22 swing back to back until the swinging movable baffles 22 trigger the signal trigger, and the bin 10 receives the signal of the signal trigger and then can control the bin 10 to close. It should be noted that, when the movable baffle 22 is pushed by the material pile to swing on the connecting member 23 at different angles, the movable baffle corresponds to different amounts of the material piled in the hopper 200, so that when people use the blanking device, the falling amount of the material in the bin 10 is the amount required to be received by the truck hopper 200 through certain calculation and multiple tests, and at this time, the bin 10 is automatically closed, so that the blanking device controls the material discharge amount of the bin 10.
In this embodiment, the position-limiting frame 20 includes a first steel pipe 201, a second steel pipe 202 provided opposite to the first steel pipe 201, and a third steel pipe 203 and a fourth steel pipe 204 for connecting the first steel pipe 201 and the second steel pipe 202; the two movable baffles 22 are symmetrically arranged on the third steel pipe 203 and the fourth steel pipe 204.
The first steel pipe 201, the third steel pipe 203, the second steel pipe 202, and the fourth steel pipe 204 are connected and fixed in sequence by welding. The limit frame 20 of the present embodiment has a simple structure and has an effect of reducing the production cost. In order to realize the position adjustment of the connecting member 23 on the limiting frame 20 formed by welding steel pipes, a strip plate (not shown) may be correspondingly fixed on the steel pipe, the connecting member 23 is correspondingly arranged on the sliding slot of the strip plate by forming the sliding slot and a plurality of limiting notches on the strip plate, and when the connecting member 23 is arranged on the limiting notch of the strip plate, the connecting member 23 is fixed in a limiting manner with respect to the strip plate.
It can be understood that, when the blanking device of the embodiment works, the lifting mechanism 30 can be used for driving the limiting frame 20 to lift, so as to realize the height adjustment of the two movable baffles 22, so that when the connecting piece 23 on the limiting frame 20 is at the same position, the movable baffles 22 with different heights are corresponding to the blanking device, and when the blanking device works, the blanking device can be suitable for quantitative blanking of trucks with hoppers 200 with different widths, and further the application range of the blanking device is improved.
In this embodiment, the lifting mechanism 30 includes a winding drum 31, a wire rope 32 wound around the winding drum 31, and a driving motor (not shown) for driving the winding drum 31 to rotate, and one end of the wire rope 32 extending out of the winding drum 31 is connected and fixed to the limiting frame 20. When the lifting mechanism 30 works, the rotation of the winding drum 31 is controlled by the driving motor, so that the winding and unwinding of the steel wire rope 32 on the winding drum 31 are realized, and the lifting or lowering of the limiting frame 20 is further driven.
