Description

Technical Field

[0001] The utility model relates to the field of coal preparation technology, in particular to a jig coal preparation machine which is convenient for adjusting the height of a baffle plate. Background Art

[0002] During the jigging process, the material continuously jigs against a fixed, moving screen. Due to the combined effects of flushing water, topwater, and horizontal bed flow, the material is separated by the combined forces of vertical and horizontal flow. The material rises and falls repeatedly in the vertically pulsating medium, forming layers and then being discharged through different outlets, achieving the desired separation.

[0003] After the materials are layered, they will be discharged through different outlets. In order to achieve this purpose, vertical baffles are generally installed on the rear side of the outlet. Materials in different layers are blocked by the corresponding baffles and discharged from the corresponding outlets. The baffles are generally fixed to the machine bed by welding or bolting. The welded baffles cannot be disassembled and are only suitable for coal selection within a specific range. Although the height of the bolted baffles can be adjusted up and down, they need to be adjusted on the bed. It is very inconvenient and dangerous for operators to operate at height. Utility Model Content

[0005] The utility model provides a jigging coal separator that is convenient for adjusting the height of the baffle plate, which adopts the following technical solutions:

[0006] A jigging coal cleaning machine with easy adjustment of the baffle plate height comprises a machine body and a baffle plate. An adjustment mechanism for driving the baffle plate to move up and down is provided on the outside of the machine body. The adjustment mechanism comprises a vertically arranged rotating drum and a power assembly for driving the rotating drum to rotate along its axis. The horizontal height of the rotating drum is constant. A threaded rod is connected to the internal thread of the rotating drum. A clearance hole is vertically opened on the side wall of the machine body. A pull rod is provided on the baffle plate and passes through the clearance hole. The pull rod is connected to the threaded rod.

[0007] By adopting the above technical solution, the power component controls the rotation of the drum with a constant position. Since the threaded rod is restricted by the pull rod and cannot rotate, when the drum rotates, it will drive the threaded rod to move up and down, thereby changing the height of the material baffle. The adjustment mechanism is simple and convenient to operate, which improves the safety of the staff's operation. It can quickly and effectively adjust the height of the material baffle to meet the material blocking needs of materials with different bed thicknesses.

[0008] Optionally, an installation box is installed outside the machine body. The power assembly includes a rotating shaft that horizontally penetrates the side wall of the installation box and the side wall of the machine body. A handwheel is installed at the outer end of the rotating shaft, and a driving bevel gear located inside the installation box is installed on the rotating shaft. The rotating cylinder rotatably penetrates the bottom plate of the installation box, and a driven bevel gear that mates with the driving bevel gear is installed at the top end of the rotating cylinder.

[0009] By adopting the above technical solution, the staff rotates the handwheel to drive the driving bevel gear, the driving bevel gear drives the driven bevel gear, and the driven bevel gear drives the rotating cylinder to rotate. The operation of this power assembly by the staff is very convenient, and the height of the baffle can be quickly adjusted.

[0010] Optionally, two clamping plates are sleeved and fixedly connected to the rotating cylinder, and are respectively located on the upper and lower sides of the bottom plate of the installation box.

[0011] By adopting the above technical solution, the two clamping plates limit the position of the rotating cylinder, prevent the rotating cylinder from moving up and down, and ensure the constancy of the position of the rotating cylinder.

[0012] Optionally, a first bearing is installed on the side wall of the machine body corresponding to the rotating shaft, a second bearing is installed on the side wall of the installation box corresponding to the rotating shaft, and a third bearing is installed on the bottom plate of the installation box corresponding to the rotating cylinder.

[0013] By adopting the above technical solution, the use of bearings effectively improves the smoothness of the rotating shaft and the rotating cylinder during rotation.

[0014] Optionally, a collar is fixedly connected to the bottom end of the threaded rod, and the pull rod is fixedly installed through the collar.

[0015] By adopting the above technical solution, a connection method is provided, which facilitates the initial assembly of the pull rod and the sleeve.

[0016] Optionally, an indicating rod is fixedly connected horizontally to the collar, and scale lines are correspondingly arranged on the outer wall of the machine body.

[0017] By adopting the above technical solution, the cooperation of the indicating rod and the scale lines is used to facilitate the accurate determination of the adjustment distance.

[0018] In summary, the present utility model includes at least one of the following beneficial technical effects:
