The technical solution of the present invention is clearly and completely described below with reference to the following embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments based on the embodiments in the present invention, without any inventive work, will be apparent to those skilled in the art from the following description.
As shown in fig. 1, the one-time mine collector for grouped mine cars of the invention comprises: the mine car comprises a flat plate 1, wherein two ends of the flat plate are provided with lap joints 2 lapped with adjacent mine cars; the inflatable cavity 3 is positioned inside the flat plate and extends along the width direction of the flat plate; one end of the exhaust pipeline is communicated with the inflation cavity, and the exhaust pipeline is arranged on the right side of the central axis of the flat plate in an offset manner; two support pieces 5 are arranged on the upper surfaces of two ends of the flat plate respectively; the two ends of the elastic plane are fixedly connected with the tops of the two supporting pieces, and the other end of the exhaust pipeline is in contact with the bottom surface of the elastic plane; the pressure sensor is positioned at the bottom of the elastic plane; the PLC receives a pressure signal transmitted by the pressure sensor; and the fan is in signal connection with the PLC, and when the PLC sends a signal to start the fan, the fan charges air into the inflation cavity.
The elastic plane of the present invention can be made of known materials such as rubber, plastic, etc., when the air blown out by the exhaust duct rises as shown in fig. 2, the elastic plane forms two arc surfaces to divide the ore into two adjacent compartments, so that the exhaust duct is biased to the right side of the central axis of the flat plate, namely, to form a long arc surface and a short arc surface, the amount of the ore divided by the long arc surface is large, and the amount of the ore divided by the short arc surface is small, so that the front compartment is ensured to be filled before the rear compartment, in other words, to ensure that the rear compartment has a loading space when the front compartment is filled, so that ore discharge can be continuously performed without overflowing the ore.
Example 1: as shown in fig. 3, there are four compartments, which are respectively called as a first compartment 8, a second compartment 9, a second compartment 10 and a tail compartment 11, and since there are only four compartments, the second compartment 10 is equivalent to a second tail compartment, there are four corresponding grouping mine car disposable ore collectors, the elastic plane width of each grouping mine car disposable ore collector matches with the corresponding compartment width so as to limit the grouping mine car disposable ore collector left and right, the opening of the inflation cavity is arranged on the side of the flat plate, the opening is communicated with the fan through a pipeline, the overlapping part is a bending part bending downwards, and the bending part is matched with the rear baffle of the immediately preceding compartment and the front baffle of the immediately following mine car compartment so as to limit the grouping mine car disposable ore collector front and back. The utility model discloses a fan, including fan, support piece, fan, the support piece is elastic support piece, and support piece is elastic material's advantage lies in can providing an elasticity restoring force, can cooperate when the fan intermittent type formula starts to provide the elasticity restoring force that lasts for the elasticity plane takes place the shake of uplift and withdrawal with certain frequency, and one reduces the energy consumption that the fan lasts work and brings, and two can make the ore on the elasticity plane fall to adjacent carriage in fast. The other end of the exhaust pipeline is in a flared bell mouth shape, the design has the advantages that the exhaust gas flow from the bell mouth is dispersed, the jacking area of the elastic plane can be enlarged, the raised radian is softer, the elastic plane area jacked up by the common straight pipe type exhaust pipeline is smaller, the area is impacted by falling ores and is easy to damage, and the bell mouth type exhaust pipeline is adopted, so that the service life of the elastic plane is longer.
The use method of the one-time mine collector for marshalling mine cars comprises the following steps: the grouped mine cars run below an ore drawing funnel, the grouped mine car disposable ore collectors are sequentially lapped between the carriages of two adjacent mine cars, a fan is respectively communicated with an inflation cavity of each grouped mine car disposable ore collector through a pipeline, the grouped mine car disposable ore collectors between the carriages of a first car and the carriages of a second car are positioned below the ore drawing funnel, and the ore drawing funnel starts ore drawing; ore falls on an elastic plane of the disposable ore collector of the grouped mine car, a pressure sensor receives a pressure signal and transmits the pressure signal to a PLC (programmable logic controller), the PLC controls a fan to start to inflate an inflation cavity, air inflated in the inflation cavity is output through an exhaust pipeline to jack up the elastic plane, so that the elastic plane forms an arc surface, the left side of the arc surface vertex is a long arc surface, the right side of the arc surface vertex is a short arc surface, ore positioned on the elastic plane naturally slides into a primary car carriage 8 and a secondary car 9 along the long arc surface and the short arc surface respectively, after the primary car carriage is filled with the ore, the grouped mine car moves forward to the position between the secondary car carriage and the secondary car carriage, the disposable ore collector of the grouped mine car is stopped when the disposable ore collector of the grouped mine car is positioned below an ore discharge funnel, the ore naturally slides into the secondary car carriage and the secondary car carriage 10 along the long arc surface and the short arc surface respectively, after the secondary car carriage is filled with the ore, the grouped cars are advanced again and so on until the next trailer car, if any, is full of ore, the grouped cars are advanced until the trailer car 11 is below the draw hopper so that the trailer car is full of ore.
The fan in the invention can work continuously, and air is blown into the inflating cavity of the one-time ore collecting device of each marshalling mine car, and also can work intermittently, so that the elastic plane is periodically raised and restored, and rhythmic shaking is formed.
