Description

Technical Field

[0001] The invention relates to the technical field of ore transportation tools, and in particular to an ore loading chute. Background Art

[0002] At present, most mines use mine cars to transport ore and rock in the shafts. Mine cars are the main transportation containers for ore and rock. Loading ore and rock into mine cars requires manual labor or equipment. For example, a scraper is used to shovel the ore and rock into the mine car, which is then transported to the outside of the shaft. Among them, the length of the commonly used mine car compartment is mostly 1.2-1.5m, and the width of the shovel bucket of the shovel for shoveling ore and rock is mostly greater than 1.5m. In addition, the volume of a single mine car is also significantly smaller than the volume of the bucket. Therefore, when shoveling ore and rock, some of the ore and rock will fall outside the mine car, and personnel will need to be organized to clean up the scattered ore and rock later, which is time-consuming and labor-intensive, delaying the construction progress. Summary of the invention

[0003] The present invention is made to solve the above-mentioned technical problems, and one of its purposes is to provide an ore loading chute that can reduce the amount of ore and rock scattered during the shoveling process.

[0004] According to one embodiment of the present invention, there is provided a loading chute, comprising: a chute body, which is surrounded by a front plate, a rear plate and two side plates, wherein the upper port is larger than the lower port, and the height of the front plate is lower than that of the rear plate; two partition plates, which are arranged in the chute body, are connected together at the upper ends, and the front and rear ends are respectively connected to the front plate and the rear plate, so that the chute body forms two lower ports; and a flexible guide portion, wherein the upper end is connected to the lower port.

[0005] As an embodiment, the front plate and the rear plate are isosceles trapezoids.

[0006] As an embodiment, the upper side length of the front panel is 2637 mm, the lower side length is 2100 mm, and the waist length is 1154 mm.

[0007] As an embodiment, the upper side length of the rear panel is 2902 mm, the lower side length is 2100 mm, and the waist length is 1736 mm.

[0008] As an embodiment, the upper side length of the side panel is 2014 mm, the rear side length is 1736 mm, the lower side length is 503 mm, and the front side length is 1154 mm.

[0009] As an embodiment, the angle between the two partition plates is 30°-90°.

[0010] As an embodiment, the angle between the two partition plates is 70°.

[0011] As an embodiment, the partition plate has an upper side length of 1084 mm, a lower side length of 503 mm, and a waist length of 610 mm.

[0012] As an embodiment, the flexible guide portion is surrounded by four rubber plates.

[0013] As an embodiment, a stiffening rod is provided on the rear side of the rear plate.

[0014] According to the above description and practice, the ore loading chute of the present invention is convenient for the shovel of the scraper to dump the ore into the chute body by setting the chute body to be low in the front and high in the back, large at the top and small at the bottom, so as to prevent the ore from being scattered around the chute. In addition, through the two lower ports below, two mine cars can be docked, and the ore in one bucket can be distributed to the two mine car compartments. The flexible guide part at the lower port can further approach or even enter the mine car compartment, so that the ore will not be scattered between the chute body and the mine car, ensuring that there will be no scattered ore around the mine car, and finally improving the efficiency of ore loading.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In this embodiment, a ore loading chute is disclosed, please refer to Figures 1 to 7 The ore loading chute in this embodiment includes a chute body 1, two partition plates 2 and two flexible guide parts 3.

[0038] The chute body 1 is enclosed by a front plate 11, a rear plate 12 and two side plates 13, forming a bucket-shaped structure with an upper port larger than a lower port, and the height of the front plate 11 is lower than that of the rear plate 12, so that the bucket of the shovel loader can reach the top of the chute body 1 without lifting it too high.

[0039] Two partition plates 2 are arranged in the chute body 1, and their upper ends are connected together, and their front and rear ends are respectively connected to the front plate 11 and the rear plate 12, so that the chute body 1 forms two lower ports. Two sides of the two partition plates 2 form two guiding slopes, which can divide the ore and rock entering the chute body 1 into two parts, and then enter the two mine cars below respectively.

[0040] The upper end of the flexible guide part 3 is connected to the lower port, which can further guide the ore into the mine car. Therefore, the chute body 1 does not need to directly contact the mine car, but the flexible guide part 3 approaches or enters the mine car. When the ore enters the mine car from the chute body 1, it is guided by the flexible guide part 3 and will not fall outside the mine car. In addition, the flexible guide part 3 can also play a dust-proof role to a certain extent, avoiding a large amount of dust from spilling out during the transportation of ore.

[0041] When in use, the loading chute can be fixed on the side of the tunnel 4 by means of round steel 5 and fall chain 6. The height of the scraper used in the shaft is 2050 mm and the width is 1820 mm; the height of the traction electric locomotive is 1540 mm, and the bottom of the loading chute is 1160 mm above the ground. If the height of the loading chute is not adjusted by the fall chain 6, the electric locomotive, the scraper and other equipment cannot pass through. The height and angle of the loading chute can be adjusted by adjusting the length of the fall chain 6, so as to facilitate the passage of the scraper, the electric locomotive and other equipment.

[0042] Before the mine car 7 arrives, the lower end of the loading chute is first raised by the fall chain 6, and after the mine car 7 arrives below the loading chute, the lower end of the loading chute is lowered by the fall chain 6, so that the lower end of the loading chute faces the carriage of the mine car 7. Then the scraper loads and unloads the ore from the upper end of the loading chute, and the ore is discharged from the lower end into the carriage of the mine car 7.

[0043] The ore loading chute can solve the problem of ore rock spilling caused by the mismatch between the size of the two-cubic-meter bucket of the scraper and the bucket of the mining truck, thereby improving production efficiency.

[0044] The ore loading chute is configured such that the chute body 1 is low in the front and high in the back, and large at the top and small at the bottom, so that the shovel of the scraper can dump the ore into it and prevent the ore from being scattered around the chute. In addition, two mine cars can be docked through the two lower ports at the bottom, and the ore in one bucket can be distributed to the two mine car compartments. The flexible guide part 3 at the lower port can further approach or even enter the mine car compartment, so that the ore will not be scattered between the chute body 1 and the mine car, ensuring that there will be no scattered ore around the mine car, and ultimately improving the efficiency of ore loading and unloading.

[0045] In one embodiment, the front plate 11 and the rear plate 12 are both isosceles trapezoids. The upper side length of the front plate 11 is 2637mm, the lower side length is 2100mm, and the waist length is 1154mm. The upper side length of the rear plate 12 is 2902mm, the lower side length is 2100mm, and the waist length is 1736mm. The upper side length of the side plate 13 is 2014mm, the rear side length is 1736, the lower side length is 503mm, and the front side length is 1154mm. With this structural form, the ore loading chute is relatively symmetrical on the left and right, and the overall size is also suitable for installation in the tunnel, and it can guide the ore and rock in the bucket into the mine car.

[0046] The angle between the two partition plates 2 is 30°-90°, which can be set according to the size of the mine car, the width of the chute body 1, etc., and finally ensure that the two lower ports can be above the two mine cars. For example, in this embodiment, the angle between the two partition plates 2 is 70°, the upper side length of the partition plate 2 is 1084mm, the lower side length is 503mm, and the waist length is 610mm. The two lower ports and the two flexible guides 3 can be directly above the two mine cars, so that the ore and rock can enter the mine car to the greatest extent when shoveling.

[0047] In one embodiment, the flexible guide part 3 is formed by enclosing four rubber plates, and its upper end is fixedly connected to the chute body 1. For example, bolt holes are provided on the front plate 11, the rear plate 12, the side plate 13 and the partition plate 2, and each rubber plate is fixed to the plate body around the lower port by bolts. This can not only realize the firm connection between the flexible guide part 3 and the chute body 1, but also facilitate disassembly and replacement after the rubber plate is severely worn after a period of use.

[0048] The flexible guide part 3 made of rubber plate can not only guide the ore and rock to completely enter the mine car, but also avoid the rigid collision between the mine car and the loading chute. Even if the mine car hits the flexible guide part 3 during transportation, it will not cause significant damage to the loading chute, which can indirectly increase the service life of the loading chute.

[0049] When the scraper is loading ore and rock, the ore and rock will fall on the rear plate 12, causing the rear plate 12 to deform, thereby affecting the shape of the entire chute body 1. Therefore, in one embodiment, a stiffening rod is provided on the rear side of the rear plate 12. For example, a plurality of angle steels and round steels are provided on the rear side of the rear plate 12 in the horizontal, vertical and oblique directions as stiffening rods to improve the deformation resistance of the rear plate 12, thereby improving the service life of the ore loading chute.

[0050] In one embodiment, each plate constituting the chute body 1 can be made of 4mm steel plates. This kind of material is commonly used in mines, and the processing process is simple. The whole body is firm and durable.

[0051] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
