[0023] like Figures 1 to 3As shown, a belt pressing device of an air cushion belt conveyor comprises a conveying chamber 1, a belt pressing wheel 2, a belt pressing wheel frame 3, two connecting seats 5 and two connecting rods 4, each of the connecting seats 5 is welded with a support 8 on the upper surface, an oil replenishing portion 6 for replenishing lubricating oil to the hinge between the connecting rod 4 and the connecting seat 5 is installed on the top of the support 8, a slide groove 11 for the flow of lubricating oil is opened on the connecting rod 4, a supporting portion 7 for supporting the oil replenishing portion 6 is arranged on the conveying chamber 1, and two groups of lifting components 9 for controlling the outflow of lubricating oil are arranged on the connecting rod 4;

[0024] Specifically, the oil replenishing part 6 is provided to replenish the lubricating oil at the hinges at both ends of the connecting rod 4, and the slide groove 11 is provided to discharge the excess lubricating oil at the hinges of the connecting rod 4 and the connecting seat 5 to one side of the pressure roller frame 3, so that the lubricating oil can be replenished at the hinges of the connecting rod 4 and the pressure roller frame 3, which effectively avoids the two ends of the connecting rod 4 from making noise or even jamming due to lack of lubricating oil during long-term use, thereby ensuring the normal use and service life of the belt pressure roller 2, and its operation method is more time-saving and labor-saving than manual lubricating oil replenishment, making the operation efficiency of filling lubricating oil higher and reducing the labor intensity of workers; the lifting component 9 is provided to control the discharge of lubricating oil on the oil replenishing part 6, to avoid continuous discharge of lubricating oil causing excess lubricating oil at the hinge, thereby avoiding waste; the supporting part 7 is provided to pull and connect the oil replenishing part 6, to ensure the stability of the installation of the oil replenishing part 6 when it is used.

[0025] like Figure 2 As shown, the oil replenishing part 6 includes a mounting box 601, the mounting box 601 is fixedly mounted on the top of the pillar 8, an oil storage box 603 is arranged inside the mounting box 601, the bottom of the oil storage box 603 and the mounting box 601 are both provided with oil drain holes 602 facing the hinged joint of the connecting seat 5 and the connecting rod 4, an oil delivery pipe 604 for delivering lubricating oil is installed on the oil storage box 603, and a through hole for the oil delivery pipe 604 to pass through is opened on the mounting box 601 and the delivery chamber 1;

[0026] Specifically, the external lubricating oil can be transported to the interior of the oil storage box 603 through the provided oil delivery pipe 604, so that the lubricating oil can be replenished at the hinges at both ends of the connecting seat 5 during use. The provided oil drain hole 602 facilitates the lubricating oil to be discharged to the hinges of the connecting rod 4 and the connecting seat 5 under the action of gravity, thereby replenishing the lubricating oil at the hinges.

[0027] like Figure 2 As shown, the side walls of the installation box 601 and the delivery chamber 1 are both connected with a "U"-shaped drag block 10 for lifting the oil delivery pipe 604;

[0028] Specifically, the drag block 10 is provided to support the oil pipe 604, thereby ensuring the stability of the oil pipe 604 during use, preventing the oil pipe 604 from shaking or even falling, and ensuring the smooth delivery of the lubricating oil to the interior of the oil storage box 603.

[0029] like Figure 3 As shown, the lifting assembly 9 includes a fixing ring 901, a fixing ring 901 is welded on the outer wall of the connecting rod 4, three fixing rings 902 equidistantly distributed are welded on the upper wall of the inner cavity of the installation box 601, a "convex" shaped sealing gasket 904 is arranged at the oil drain hole 602, a pulling rope 903 whose movable end is connected to the sealing gasket 904 is connected between the fixing ring 901 and the three fixing rings 902, a rebound part 905 for driving the sealing gasket 904 to move downward is arranged on the sealing gasket 904, the sealing gasket 904 is made of oil corrosion resistant material, and a vertical hole for the pulling rope 903 to pass through is opened on the oil storage box 603;

[0030] Specifically, the setting of the pulling rope 903 can pull the sealing gasket 904 upward to the oil drain hole 602 under the pulling action of the connecting rod 4, thereby achieving the effect of sealing the oil drain hole 602. When the belt pulley 2 is pushed upward, the sealing gasket 904 can be pulled away from the oil drain hole 602 under the pulling cooperation of the rebound part 905, so that the lubricating oil inside the oil storage box 603 can flow downward to the hinge between the connecting seat 5 and the connecting rod 4, thereby achieving the effect of replenishing the lubricating oil.

[0031] like Figure 3 As shown, the rebound part 905 includes four brackets 9051, and four brackets 9051 arranged in a matrix are welded to the bottom of the installation box 601. The side wall surface of the bracket 9051 and the bottom of the sealing pad 904 are connected with a damping spring 9052 and a telescopic rod 9053;

[0032] Specifically, the damping spring 9052 and the telescopic rod 9053 are arranged to pull the bottom of the sealing gasket 904. When the pressure roller 2 is used normally, that is, the pressure roller 2 is not in contact with the conveying tape, it is pulled by the connecting rod 4. At this time, the damping spring 9052 and the telescopic rod 9053 are stretched and deformed, thereby sealing the sealing gasket 904 at the oil drain hole 602 to prevent the lubricating oil from flowing out. When the pressure roller 2 is not used normally, that is, the pressure roller 2 moves upward under the influence of the conveying tape, the damping spring 9052 and the telescopic rod 9053 can drive the sealing gasket 904 to retract downward under their telescopic action, thereby making the sealing gasket 904 away from the oil drain hole 602 so that the lubricating oil can flow out downward.

[0033] like Figure 2As shown, the support portion 7 includes a connecting plate 703, and two connecting plates 703 are obliquely arranged above each installation box 601. The side wall surface of the conveying chamber 1 and the upper surface of the installation box 601 are welded with a mounting frame 701, and the mounting frame 701 is rotatably connected to a rotating shaft 702 fixedly connected to the outer wall surface and the connecting plate 703;

[0034] Specifically, the upper surface of the installation box 601 can be pulled by the provided connecting plate 703, thereby effectively improving the installation stability of the installation box 601 and the stability during use.

[0035] When in use, the user can transport the lubricating oil to the inside of the oil storage box 603 through the oil delivery pipe 604. When the conveying belt is not in use normally, the conveying belt will move upward due to the excessive support force of the gas ejected from the air jet port, thereby contacting the pressure roller 2 and pushing the pressure roller 2 to move upward. At this time, the pressure roller 2 and the connecting rod 4 will be lifted around the connecting seat 5. When the connecting rod 4 is lifted, the sealing gasket 904 can be driven to move downward under the cooperation of the retraction of the damping spring 9052 and the telescopic rod 9053, so that the oil drain hole 602 loses its blockage. Under the action of gravity, the lubricating oil inside the oil storage box 603 can flow downward, thereby replenishing the lubricating oil to the hinge of the connecting rod 4 and the connecting seat 5, and the excess lubricating oil can be discharged to the hinge of the pressure wheel frame 3 and the connecting rod 4 along the slide groove 11. When the tape is in normal use, the pressure wheel 2 does not contact the conveyor tape. At this time, the pulling rope 903 can pull the sealing pad 904 upward. When the sealing pad 904 moves upward, the damping spring 9052 and the telescopic rod 9053 are pulled to stretch and change, so that the oil drain hole 602 can be blocked. If it is necessary to add lubricating oil to the hinge, the power of the fan can also be increased, so that the conveyor tape that was originally in normal use moves upward to achieve the purpose of adding lubricating oil (the conveyor tape, the air jet and the fan are all structures contained in the publication number CNCN219238225U, and the connection method and installation position of the conveying chamber 1, the pressure wheel 2, the pressure wheel frame 3, the two connecting seats 5 and the two connecting rods 4 are all introduced in the publication number CNCN219238225U, so they will not be repeated here).

[0036] In summary: the oil replenishing part 6 is provided to replenish the lubricating oil at the hinges at both ends of the connecting rod 4, and the slide groove 11 is provided to discharge the excess lubricating oil at the hinge of the connecting rod 4 and the connecting seat 5 to one side of the pressure roller frame 3, so that the lubricating oil can be replenished at the hinge of the connecting rod 4 and the pressure roller frame 3, which effectively avoids the two ends of the connecting rod 4 from making noise or even jamming due to lack of lubricating oil during long-term use, thereby ensuring the normal use and service life of the belt pressure roller 2, and its operation method is more time-saving and labor-saving than manual lubricating oil replenishment, making the operation efficiency of filling lubricating oil higher and reducing the labor intensity of workers; the lifting component 9 is provided to control the discharge of lubricating oil on the oil replenishing part 6, to avoid continuous discharge of lubricating oil causing excess lubricating oil at the hinge, thereby avoiding waste; the supporting part 7 is provided to pull and connect the oil replenishing part 6, to ensure the stability of the installation of the oil replenishing part 6 when it is used.
