A crushing and conveying device for gold mining

Abstract

This utility model provides a crushing and conveying device for gold mining, relating to the field of gold mining. The crushing and conveying device for gold mining includes a conveying frame, a screening mechanism, and a crushing mechanism. A tilting mechanism is connected to the rear of the screening mechanism. The tilting mechanism includes a driving plate and a scraper. The driving plate is disposed inside the crushing mechanism, and the top of the scraper is connected to the bottom of the driving plate. The bottom of the screening mechanism is connected to the top left side of the conveying frame. This crushing and conveying device for gold mining, by setting up a tilting mechanism, uses the output shaft of a second motor at the top of the arc-shaped plate to rotate, which in turn rotates the driving plate at the bottom of the connecting plate. The rotation of the driving plate then rotates the scraper, tilting the unscreened ore blocks above the crushing mechanism so that they fall and are re-crushed. This avoids secondary crushing of the ore blocks, improves the crushing efficiency, reduces energy consumption during device operation, and lowers the cost of gold ore processing.

Description

Technical Field

[0001] This utility model relates to the field of gold mining technology, specifically a crushing and conveying device for gold mining. Background Technology

[0002] Gold mining refers to the development and extraction of gold deposits. Different gold deposits require different mining methods, the specific method depending on factors such as the deposit and the mining environment. After mining, gold ore needs to be crushed to facilitate transportation. The crushing process requires a step-by-step crushing process, first breaking the raw material into coarse material and then further crushing the coarse material into medium material. Therefore, a crushing and conveying device is needed for this process.

[0003] Patent CN218423046U discloses a crushing device for gold mining. This device utilizes a motor to drive a drive wheel, driven wheel, rotating rod, and crushing pins. Two sets of crushing pins crush the gold ore. A fixed box provides support for one end of the rotating rod. The crushed gold ore falls onto the top of a screen plate. The impact of the falling ore causes a spring to extend and retract. The fixed plate supports the spring, which causes the screen plate to vibrate up and down, preventing clogging. Medium or fine material is screened out of the screen plate, while coarse material is conveyed out of the crushing box from the top of the screen plate. The lifting rod and fixed rod provide protection for the spring, and the two sets of discharge ports facilitate the classified transport of the gold ore.

[0004] However, the coarse ore material from the screening section of the crushing device used for gold mining needs to be transferred to the next-level crushing device for secondary crushing. The gold mine crushing efficiency is low, and the crushing process requires the operation of multiple devices, resulting in high energy consumption and increased gold mine crushing costs. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention provides a crushing and conveying device for gold mining, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a crushing and conveying device for gold mining, comprising a conveying frame, a screening mechanism for screening gold ore blocks, and a crushing mechanism for crushing gold ore blocks.

The bottom of the screening mechanism is connected to the top left side of the conveying frame. The crushing mechanism is connected to the front side of the screening mechanism.

[0007] By adopting the above technical solution, the rotation of the drive plate can drive the scraper to rotate against the inner wall of the screen cylinder, causing the unscreened ore blocks to be flipped up and fall from above the crushing mechanism for re-crushing.

[0008] Preferably, the flipping mechanism further includes an arc-shaped plate and a second motor, the front side of the arc-shaped plate being connected to the rear side of the screening mechanism, and the bottom of the second motor being connected to the top of the arc-shaped plate.

The connecting plate is connected to one end of the rotating shaft, and the bottom of the connecting plate is connected to the top of the driving plate.

[0011] By adopting the above technical solution, the output shaft of the second motor can be rotated to drive the rotating shaft to rotate, the rotating shaft to drive the connecting plate to rotate, the connecting plate to drive the rotating plate to rotate, thereby driving the scraper to rotate and flip the ore block.

[0012] Preferably, the screening mechanism includes an outer box and a discharge hopper. The bottom of the outer box is connected to the top left side of the conveyor frame, the lower rear side of the outer box is connected to the front side of the arc plate, the center of the rear side of the outer box is rotatably connected to the side of the rotating shaft, and the bottom of the discharge hopper is connected to the top of the outer box.

[0013] By adopting the above technical solution, the hopper at the top of the outer box can be used to facilitate the feeding of gold ore blocks, reducing the possibility of ore blocks scattering around the device.

[0014] Preferably, the screening mechanism further includes a screening cylinder and a discharge hopper. The front and rear sides of the screening cylinder are connected to the upper front and rear sides of the inner wall of the outer box. The inner wall of the screening cylinder is in contact with the bottom of the scraper. The top of the discharge hopper is connected to the bottom of the outer box.

[0015] By adopting the above technical solution, ore blocks can be screened using a screening cylinder, thereby achieving the purpose of screening ore blocks.

[0016] Preferably, the crushing mechanism includes a fixed frame and a first motor, the fixed frame being connected to the front side of the outer casing, and the front side of the first motor being connected to the rear side of the inner wall of the fixed frame.

[0017] By adopting the above technical solution, the first motor connected by the fixed frame can provide power support for the operation of the crushing mechanism, and the connection method of the fixed frame ensures the dissipation of heat.

[0018] Preferably, the crushing mechanism further includes a main gear and a left rotating rod.

The left rotating rod is connected to the rear side of the main gear, and the side of the left rotating rod is rotatably connected to the left side of the front of the outer casing.

The right rotating rod is connected to the rear side of the driven gear, the side of the right rotating rod is rotatably connected to the right side of the front of the outer casing, and the front side of the driven roller is connected to one end of the right rotating rod.

[0021] By adopting the above technical solution, the rotation of the gear can drive the rotation of the right rotating rod, which in turn drives the rotation of the driven roller.
