Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary ore-clearing equipment and relates to an ore-clearing device applied to a narrow space at the bottom of a vibrating ore-drawing machine. Background Art

[0002] Vibrating ore-conveying machine is the main equipment for conveying ore in metal mines. It uses the vibration motor as the power source and the centrifugal force generated by the eccentric blocks installed at both ends of the vibration motor main shaft to obtain the exciting force, driving the ore in the ore-conveying machine to continuously jump forward to the crusher cavity for crushing.

[0003] When the equipment is installed, a certain amount of space is reserved between the discharge port of the vibrating ore discharger and the basic platform to ensure continuous vibration of the ore discharger. During the ore discharge operation, the ore is continuously accumulated when entering the crushing chamber of the crusher through the discharge port to form an inclined surface, causing the ore to continuously accumulate under the ore discharger. The discharge port and the vibrating ore discharger plate have indirect rigid contact. The operating personnel need to climb to the bottom of the vibrating ore discharger every shift and use a shovel to clean up the accumulated ore. The main problems are as follows: (1) When the vibrating ore discharger is working, the ore at the crushing cavity mouth accumulates continuously to form an inclined surface, so that the ore is blocked below the discharge port, forming an indirect rigid contact between the discharge port and the vibrating table, which can easily cause the vibrating ore discharger to overload and burn out the motor, seriously affecting the normal operation of the entire crushing system; (2) The ore enters the basic platform at the bottom of the discharge port of the vibrating ore discharger, and the ore accumulates on the basic platform, causing the vibrating ore discharger to descend slowly; (3) Due to the small operating space at the bottom of the vibrating ore discharger, there are certain risks for operators when cleaning the ore. The ore is sticky and has high moisture content, making it difficult to clean, which brings great difficulty to the crushing and cleaning operations. Utility Model Content

[0004] The utility model aims to provide a ore-clearing device for use in the narrow space at the bottom of a vibrating ore-discharging machine in response to the problems existing in the prior art, thereby solving the following problems in the existing ore-clearing method: ① the ore-discharging machine is in indirect contact with the ore accumulation, which may easily lead to the motor burning out; ② the vibrating ore-discharging machine lowers the ore slowly; ③ the ore has high viscosity and moisture content, which is difficult to clean.

[0005] To this end, the utility model adopts the following technical solutions:

[0006] A ore-clearing device applied to the narrow space at the bottom of a vibrating ore-discharging machine, characterized in that it comprises two symmetrically arranged columns with a supporting crossbeam provided therebetween, a plurality of first ear plates are provided on the top of the supporting crossbeam, the first ear plates are vertically arranged, two supporting plates are provided on the side of the supporting crossbeam, and the two are arranged in parallel, a second ear plate and a limiting plate are provided on the top of each supporting plate, a pushing plate is provided on the side of the limiting plate, a connecting plate, a shift fork and an electro-hydraulic push rod are provided on the side wall of the pushing plate in sequence, the connecting plate and the shift fork are rotatably connected by a latch, and the shift fork and the electro-hydraulic push rod are fixedly connected.

[0007] Furthermore, the first ear plate comprises a square plate body, a top of which is provided with an arc-shaped groove, and the second ear plate has the same shape as the first ear plate.

[0008] Furthermore, the pushing plate is U-shaped, and its bottom is in contact with two support plates.

[0009] The beneficial effects of the utility model are:

[0010] The utility model can reasonably utilize the ore clearing device in a narrow space to quickly clear the accumulated ore at the bottom of the ore discharge port, thereby ensuring the ore discharge efficiency and reducing the safety risk of operators cleaning the powder ore at the bottom of the vibrating ore discharger.

[0015] The technical solution of the utility model is described below in conjunction with the accompanying drawings and implementation methods.

[0016] like Figure 1 As shown, a ore cleaning device applied to the narrow space at the bottom of a vibrating ore-discharging machine comprises a supporting platform, wherein the supporting platform comprises two symmetrically arranged columns 1, and a supporting crossbeam 2 is arranged between the two, and a plurality of first ear plates 3 are arranged on the top of the supporting crossbeam 2, and the first ear plates 3 are arranged vertically, and two supporting plates 4 are arranged on the side of the supporting crossbeam 2, and the two are arranged in parallel.

[0017] A second ear plate 5 and a limiting plate 6 are provided on the top of each support plate 4 ; specifically, the first ear plate 3 comprises a square plate body with an arc-shaped groove on the top, and the second ear plate 5 has the same shape as the first ear plate 3 .

[0018] like Figure 2 As shown, a pushing plate 7 is provided on the side of the limiting plate 6, and the pushing plate 7 is U-shaped, and its bottom is in contact with the two supporting plates 4; the side wall of the pushing plate 7 is provided with a connecting plate 8, a shift fork 9 and an electro-hydraulic push rod 10 in sequence, and the connecting plate 8 and the shift fork 9 are rotatably connected by a latch 11, and the shift fork 9 and the electro-hydraulic push rod 10 are fixedly connected.

[0019] like Figure 3 As shown, the utility model is in use as follows:

[0020] First, columns 1 are installed on both sides of the bottom of the vibrating ore-dumping machine 12. The bottom of the column 1 is welded to the pre-buried anchor rod of the foundation, and the middle part is horizontally welded to the supporting beam 2. Four symmetrical first ear plates 3 are longitudinally arranged above the supporting beam 2. The end of the supporting plate 4 is welded to the side of the supporting beam 2, and the second ear plate 5 and the limit plate 6 are welded in the middle of the supporting plate 4. The limit plate 6 can make the pushing plate 7 shrink to the tail of the basic platform 13 to ensure that the accumulated ore cannot slide to the bottom of the vibrating ore-dumping machine 12. The first ear plate 3 and the second ear plate 5 are both used to fix and limit the electro-hydraulic push rod 10.

[0021] Next, the electro-hydraulic push rod 10 is connected to the pushing plate 7 through the connecting plate 8 and the fork 9 in sequence. The length of the pushing plate 7 is consistent with the width of the discharge port of the vibrating ore discharger 12. The support plate 4 is connected to the basic platform 13. After each ore discharge operation is completed, the operator reasonably uses the electro-hydraulic push rod 10 to drive the pushing plate 7 to push the accumulated ore out of the discharge port, so that the accumulated ore in front of the discharge port can be quickly cleared.
