Description

Technical Field

[0001] The invention belongs to the technical field of coal mine equipment, and in particular relates to a coal outlet translation type automatic coal loading device. Background Art

[0002] Coal mines produce a huge amount of coal every day, and there are also many large vehicles entering the mine to transport coal. The current method of loading coal is to set up a scale at the coal loading point and set up a fixed coal discharge port above the scale; the coal discharge port is connected to the silo through a conveyor belt.

[0003] When loading coal, the vehicle stops on the scale and checks the type and weight of the loaded coal with the operator. The operator starts the equipment, opens the coal outlet after the silo is discharged, and releases the coal. The coal falls directly into the truck bed. The operator adjusts the coal release speed according to the weight displayed on the scale, observes the height of the coal pile in the truck bed, and informs the driver through the intercom to move the vehicle forward at an appropriate time to avoid spilling due to the excessive height of the coal pile. Since most coal transport vehicles are large vehicles with a load capacity of dozens of tons and a long truck bed, the forward movement of the vehicle needs to be continued several times. The loading process consists of several fixed-point coal dropping methods, so multiple coal piles will be formed in the truck bed. The height of these coal piles is usually close to or exceeds the height of the baffle, so they need to be flattened so that they can be covered with a top cloth for closed transportation.

[0004] The entire process of existing coal loading requires close cooperation between the driver and the operator, and the timing and distance of the vehicle moving forward must be just right. If it is ahead of the vehicle, the coal loading will be insufficient, and it will be necessary to reverse and reload, which will reduce the efficiency of coal loading; if it lags behind, the coal pile will be too high, which will cause inconvenience to the later top cloth covering, and even cause coal blocks to fall, adding extra cleaning work.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0043] See also Figure 1 The present invention provides a coal outlet translation type automatic coal loading device, comprising

[0044] Silo 100, for storing coal;

[0045] The transfer conveyor belt 200 is connected to the silo 100 and transports the coal in the silo 100 to the loading point;

[0046] A weighbridge 600, which is installed at the loading point to weigh the transport vehicle 500;

[0047] A mobile coal loading mechanism 400, arranged above a weighbridge 600, is used to load coal into a bucket of a transport vehicle 500;

[0048] The fixed drop hopper 300 is arranged above the mobile coal loading mechanism 400 and is used to collect the coal delivered by the transfer conveyor belt 200 and drop it onto the mobile coal loading mechanism 400;

[0049] See also Figure 2 The mobile coal loading mechanism 400 includes a mobile frame 1 that can reciprocate in the horizontal direction; a loading conveyor belt 13 is provided on the mobile frame 1; and a discharge hopper 12 is fixed on the mobile frame 1 for dropping the coal transported by the loading conveyor belt 13 into the bucket of the transport vehicle 500 in a certain form;

[0050] See also Figure 3 , rollers 11 are respectively provided on both sides of the mobile frame 1, and the rollers 11 are mounted on the guide rail frame 2; Figure 5 The mobile frame 1 is also provided with a driving motor 14 for driving the mobile frame 1 to make reciprocating motion;

[0051] Preferably, the driving motor 14 is connected to a reducer 15; the reducer 15 is transmission-connected to a driving shaft 16; the transmission connection mode of the present invention is chain transmission or gear transmission.

[0052] Combination Figure 1 , the transport vehicle 500 stops at a predetermined position, and the discharge hopper 12 is located at one end above the vehicle bucket; the loading conveyor belt 13 continuously delivers the coal to the discharge hopper 12 and drops it into the vehicle bucket from there, and at the same time, the moving frame 1 moves steadily and evenly along the direction of the vehicle bucket until it moves to the tail of the vehicle bucket; after reaching the predetermined loading amount, the transfer conveyor belt 200, the loading conveyor belt 13 and the drive motor 14 stop quickly in sequence to complete the coal loading.

[0053] Since the discharge hopper 12 drops coal for loading at a uniform speed, the coal will not form an excessively high coal pile in the truck bucket. By matching the reasonable moving speed of the mobile frame 1 and the coal carrying capacity of the loading conveyor belt 13, the technicians can form a nearly flat coal layer in the truck bucket, eliminating the need for later flattening operations and improving operating efficiency. At the same time, the operator is no longer required to manually control the coal loading process, which improves the automation of the coal loading process and saves labor.

[0054] See also Figure 3 As an embodiment, the outlet position of the discharge hopper 12 of the present invention is parallelly provided with a plurality of partition plates 121 for dispersing coal; the coal is evenly dispersed on the partition plates 121 and falls into the bucket in a waterfall shape, making the top of the coal seam more flat.

[0055] See also Figure 4 As an embodiment, the outlet position of the discharge hopper 12 of the present invention is evenly provided with three discharge forks 122; the coal is diverted at the discharge fork 122, and the original coal falling method concentrated in one stream on the center line of the bucket is optimized to three streams of coal falling into the bucket; the phenomenon of ridges on the top of the coal pile caused by the coal falling in one stream is avoided, making the top of the coal pile smoother.

[0056] See also Figure 6 The guide rail frame 2 is also provided with a wire groove 21, combined with Figure 7 The mobile frame 1 is fixed with a power connection piece 17 electrically connected to the wire trough 21; the power connection piece 17 is provided with an electric contact 171 electrically connected to the drive motor 14; see Figure 8 , a wire 22 is arranged in the wire groove 21, and a brush 172 for brushing electricity from the wire 22 is arranged on the power receiving member 17. Further, the wire 22 is in two groups, so as to avoid power failure when the brush 172 of one group is separated from the wire 22.

[0057] Since the mobile frame 1 reciprocates in the working state and a large amount of coal is transported in one operation process, a certain vibration will be generated. After long-term use, the exciting force generated by the vibration will loosen the contact between the brush 172 and the conductor 22, thereby causing a power outage.

[0058] In order to absorb the vibration energy of the vibration acting on the power connection part 17, see Fig. 9 , the power connection part 17 is installed in the damping frame 3; the damping frame 3 has an upper cover plate and a lower cover plate, and a damping cylinder 34 is fixed on the upper cover plate and the lower cover plate respectively; the damping cylinder 34 has a cylinder body, and the cylinder body is movably connected to a piston, and the piston is connected to the power connection part 17; hydraulic oil is filled in the cylinder body, and the cylinder bodies of the two damping cylinders 34 are connected by a connecting pipe 35; a buffer spring 33 is also provided between the upper cover plate, the lower cover plate and the power connection part 17; when the power connection part 17 tends to move up or down or moves slightly due to vibration, the piston is driven to work on the hydraulic oil to consume most of the vibration energy, and the remaining small part of the vibration energy is absorbed in the buffer spring 33 and converted into elastic energy; then the buffer spring 33 releases the elastic energy and drives the piston to work on the hydraulic oil, which is completely consumed. This process consumes the energy generated by the vibration in the damping cylinder 34, thereby greatly reducing or even avoiding the amplitude of the power connection piece 17, protecting the contact connection between the brush 172 and the wire 22, and achieving stable power supply under vibrating working conditions.

[0059] Furthermore, the damping frame 3 is also provided with two rack plates 31 along the movement direction of the mobile frame 1, and the power connection part 17 is also provided with a balancing gear 32 that cooperates with the rack transmission of the rack plate 31; the balancing gear 32 cooperates with the rack plate 31 to balance the force exerted on the power connection part 17 when the mobile frame 1 reciprocates, thereby preventing it from rotating and destroying the contact connection between the brush 172 and the wire 22.

[0060] The present invention has three balancing gears 32, one of which is provided on one side surface of the power connection member 17, and two are provided on the other side surface, so as to prevent the power connection member 17 from twisting in a vertical plane.

[0061] See also Fig.10 As an embodiment, two balancing gears 32 are respectively provided on the two side surfaces of the power connection member 17.

[0062] The present invention uses a loading conveyor belt 13 to transport coal on the mobile frame 1, and uses a brush to draw electricity. The overall structure is compact and the vertical height is small. It can be retrofitted under the existing fixed drop hopper 300 without dismantling and rebuilding the existing facilities. The transformation cost is low, the construction period is short, and it has good promotion.

[0063] In summary, the present invention provides a coal outlet translation type automatic coal loading device. By setting a mobile coal loading mechanism, the discharge hopper is made to drop coal into the truck in a uniform motion, so that the coal will not form an excessively high coal pile in the truck bucket. By matching the reasonable moving speed of the mobile frame and the coal carrying capacity of the loading conveyor belt, a nearly flat coal layer can be formed in the truck bucket, avoiding coal scattering and eliminating the later flattening operation, thereby improving the working efficiency. At the same time, the operator is no longer required to manually control the coal loading process, which improves the automation of the coal loading process and saves labor.

[0064] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
