Problems solved by technology

[0002] In the process of open-pit mining, it is necessary to screen the mined ore and classify the ore according to the particle size. Now when the ore is processed by a multi-stage screening device, the ore is screened through multiple sets of screens inside the screening device. Screening, however, the number of screens inside the screening device is fixed, so that the number of times of ore screening is fixed. If the ore needs to be screened more times, only other equipment can be used, resulting in certain limitations of the screening device. To this end, we propose a post-transportation multi-stage screening device and method for open-pit mining

Embodiment 1

[0027] The invention provides a technical solution: a multi-stage screening device after transportation for open-pit mining, please refer to figure 1 , including the mounting plate 1;

[0028] see figure 1 , Four sets of feet are fixedly installed at the four corners of the outer wall at the bottom of the mounting plate 1, and the outer wall of the top of the mounting plate 1 is provided with a screening box 2, and the inner cavity of the screening box 2 is uniformly provided with a screen 3, and the screen 3 is arranged inclined to the left or right , to facilitate the discharge of ore from the discharge pipe 4, the connection part of the screening box 2 and the screen 3 is slotted, the left and right ends of the screen 3 are directly inserted into the inner cavity of the slot, and the screen 3 can move forward Remove from the slotted inner cavity, so that the screen 3 can be removed from the inner cavity of the screening box 2, and the screen 3 is evenly distributed in the ...

Embodiment 2

[0034] see figure 1 and Figure 5 , on the basis of Embodiment 1, a motor 12 is fixedly installed on the outer wall on the right side of the top of the mounting plate 1, the motor 12 is a servo motor, and can rotate forward and reverse with the screw 13, and the left output end of the motor 12 is fixed to the screw 13 Connection, the outer wall of the screw rod 13 is sleeved with a screw sleeve 14, the inner wall of the screw sleeve 14 is provided with threads, the rotation of the screw rod 13 can move with the screw sleeve 14 left and right, the left end of the screw sleeve 14 is fixedly connected with the push block, and the bottom of the push block is connected with the top of the mounting plate 1 Sliding connection, so that the screw sleeve 14 can only move left and right without rotation, and the outer wall on the left side of the push block fits with the outer wall on the right side of the screening box 2, and the outer wall at the bottom of the screening box 2 is fixedl...

Abstract

The invention discloses a post-transportation multi-stage screening device for open-pit mining in the technical field of mining. The device comprises a mounting plate, four groups of support legs arefixedly mounted at four corners of the outer wall of the bottom of the mounting plate, a screening box is arranged on the outer wall of the top of the mounting plate, and screens are uniformly arranged in an inner cavity of the screening box. Discharging pipes are arranged on the outer walls of the left side and the right side of the screening box correspondingly, the screening box comprises a lower box body, an upper box body is movably installed at the outer wall of the top of the lower box body, a top cover is movably installed at the outer wall of the top of the upper box body, and the inner wall of the bottom of the screening box is fixedly connected with a guide block. Fixing rods are pulled towards the outer side in the device, the fixing rods do not make contact with connecting blocks, the top cover is disconnected with the upper box body, the number of screens is increased by adding other upper box bodies, the ore screening frequency of the screening device can be increased toa certain degree according to needs, and the situation that the screening device cannot meet the needs due to the fact that the ore needs to be screened excessively is avoided.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a post-transportation multi-stage screening device and method for open-pit mining. Background technique [0002] In the process of open-pit mining, it is necessary to screen the mined ore and classify the ore according to the particle size. Now when the ore is processed by a multi-stage screening device, the ore is screened through multiple sets of screens inside the screening device.
