Description

Technical Field

[0001] The utility model relates to the field of metering devices for mine loading stations, in particular to a metering device for improving the loading coefficient of a skip. Background Art

[0002] The weighing bucket of the inclined shaft loading station is used to measure the tonnage of the ore being unloaded and stored. When the transport bucket reaches the loading position, the control cylinder is activated by the control element to open the gate, and the ore in the bucket box is loaded into the bucket along the chute. Figure 1 As shown, during the lifting process of the inclined shaft 201 using the skip 3, since the outlet angle of the metering device of the loading station 1 is installed at 60°, the process of loading into the skip 3 will cause ore accumulation in the metering device and a low loading coefficient at the inclined upper end of the skip 3 box. Utility Model Content

[0003] In view of the problems existing in the background technology, the utility model proposes a metering device for improving the loading coefficient of the skip, and reduces the accumulation of ore in the metering device during loading by resetting the material discharge angle of the metering device.

[0004] To achieve the above object, the utility model adopts the following technical scheme: a metering device for improving the loading coefficient of a skip, the metering device has a discharge port for unloading, the discharge port is composed of a side plate and a bottom plate, and the discharge angle formed by the bottom plate and the horizontal direction can make the unloading direction perpendicular to the skip;

[0005] Wherein, the cutting angle formed by the bottom plate and the horizontal direction is 120°.

[0006] Beneficial effects of the utility model: the utility model increases the discharge amount of the skip during loading by resetting the discharge angle of the metering device, reduces the accumulation of ore in the metering device, and because the discharge port can be vertical to the skip for unloading, the upper inclined part of the skip along the inclined shaft direction can be fully loaded.

[0010] The serial numbers in the figure are respectively represented as: 1, loading station; 101, metering device; 102, unloading angle; 102a, original unloading angle; 103, unloading port; 104, bottom plate; 105, side plate; 2, ore body; 201, inclined shaft; 3, skip; 301, ore; 302, upper inclined part. DETAILED DESCRIPTION

[0011] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0012] See also Figure 1 The figure is a schematic diagram of the inclination angle of the original measuring bucket. It can be seen from the figure that the measuring device 101 is installed at the lower end of the loading station 1, so as to measure the tonnage of the ore discharged from the lower end outlet. However, the angle between its outlet angle and the horizontal direction is 60°, that is, the original discharge angle 102a is 60°. When discharging, the discharge of the original discharge port 103 is close to vertically discharging downward. Due to the existence of the inclined shaft 201 set in the ore body 2, the transport box of the skip 3 will be tilted during the process of transporting the ore 301 along the inclined shaft 201, resulting in the ore 301 not being loaded to the upper inclined part 302 of the skip 3 as shown in the figure. At the same time, it will also cause the material to accumulate in the measuring device 101.

[0013] See also Figure 2 and Figure 3 The metering device 101 involved in the utility model has a discharge port for unloading, and the discharge port is a box structure composed of a side plate 105 and a bottom plate 104. After the metering device 101 measures the tonnage of the ore 301 to be discharged, the material can be discharged through the discharge port. The discharge angle 102 formed by the bottom plate 104 and the horizontal direction can make the discharge direction perpendicular to the bucket 3. When unloading the material, the material can be at a certain angle along the bottom plate 104 of the discharge port, and slowly accumulate toward the bottom of the bucket 3 until the entire bucket 3 is filled. The ore 301 that the bucket 3 can load is fixed, so the metering device 101 measures according to the loading capacity of the bucket 3. When the bucket 3 is filled with ore 301, the ore 301 in the metering device 101 can be just discharged, thereby further avoiding the accumulation of ore 301 in the metering device 101.

[0014] In some preferred embodiments, the material discharge angle 102 formed by the bottom plate 104 and the horizontal direction is 120°. The material discharge angle of 120°, combined with the parabola of the ore 301 discharged and the inclination angle of the inclined shaft 201, can make the ore 301 better filled, the upper inclined part 302 of the bucket 3 material box, and further improve the full load factor of the bucket 3.

[0015] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
