[0030] In some existing flotation devices, the scraper shafts of two flotation machines are connected by a cross shaft, and the middle of the cross shaft is close to the nylon sleeve as a fulcrum. During the flotation operation of the flotation machine, the nylon sleeve is prone to wear, resulting in wear of the cross shaft, which easily affects the operating efficiency of the flotation device.

[0031] The two flotation machines in the flotation device provided in this embodiment can avoid the situation where the cross shaft is worn due to the wear of the nylon sleeve through the connection component, thereby affecting the operating efficiency of the flotation device.

[0032] The specific structure of a flotation device provided by an embodiment of the utility model and the corresponding technical effects it brings are described in detail below in conjunction with the patent drawings.

[0033] Please refer to Figure 1-Figure 2 A flotation device provided by an embodiment of the utility model includes two flotation machines (not shown in the figure) and a connecting assembly 200.

[0034] Two flotation machines are arranged at intervals along a preset direction, and each flotation machine includes a scraper shaft 100, on which a plurality of scrapers arranged at intervals along the axial direction are fixedly connected, one end of the scraper shaft 100 has a connecting piece, and the connecting assembly 200 includes a connecting shaft 210, a first bearing seat 230 and a first bearing 240, the first bearing 240 is installed in the first bearing seat 230, the connecting shaft 210 is passed through the first bearing 240, and the two ends of the connecting shaft 210 are respectively provided with a first matching piece and a second matching piece. It should be noted that the first bearing seat 230 is connected to the frame of the flotation device (not shown in the figure).

[0035] The preset direction is consistent with the axial direction of the scraper shaft 100 , the connecting piece of one of the two flotation machines is connected to the first matching piece, and the connecting piece of the other of the two flotation machines is connected to the second matching piece.

[0036] It should be noted that the scraper shafts 100 in the two flotation machines in this embodiment are connected together by the connecting shaft 210. Therefore, the scraper shafts 100 in the two flotation machines only need the driving device of one scraper machine to realize the rotation of the scrapers in the two flotation machines.

[0037] It can be understood that the scraper shafts 100 of the two flotation machines are connected together by the connecting shaft 210, and the first bearing seat 230 is used as a fulcrum. The first bearing seat 230 is provided with a bearing, which can reduce the friction on the connecting shaft 210, thereby effectively avoiding the situation where the operating efficiency of the flotation device is affected due to the wear of the connecting shaft 210.

[0038] Optionally, in order to stably support the connecting shaft 210 , in this embodiment, the first bearing seat 230 is located in the middle of the connecting shaft 210 .

[0039] Optionally, the first matching member and the second matching member are detachably connected to the connecting members of the two flotation machines, respectively. It is understandable that since the first matching member and the second matching member are detachably connected to the connecting members of the two flotation machines, respectively, it is convenient for users to replace the connecting device.

[0040] In detail, the connecting piece is fixedly connected to the scraper shaft 100, and the connecting piece is a connecting flange 130, thereby ensuring that the connecting flange 130 can rotate along with the scraper shaft 100, and the first matching piece and the second matching piece are both fixedly connected to the connecting shaft 210, and the first matching piece and the second matching piece are both matching flanges 220, thereby being able to rotate together with the connecting shaft 210.

[0041] In this embodiment, the connecting flange 130 is a stainless steel flange, and the matching flange 220 is also a stainless steel flange. It can be understood that the main material of the stainless steel flange is stainless steel, which has excellent corrosion resistance, whether it is acid, alkali, salt solution or atmospheric environment, can show good corrosion resistance, and the stainless steel flange material has high strength, good rigidity, and is not easy to deform after long-term use, which can ensure the stability of the connection between the connecting shaft 210 and the scraper shaft 100.

[0042] Optionally, in this embodiment, the connecting flange 130 is fixedly connected to the scraper shaft 100 via a key, and the matching flange 220 is fixedly connected to the connecting shaft 210 via a key.

[0043] It can be understood that the key can be a flat key or a spline, that is, a keyway can be opened on the scraper shaft 100, and a flat key can be inserted into the hole of the connecting flange 130, so that the connecting flange 130 is connected to the scraper shaft 100. Similarly, a keyway can be opened on the connecting shaft 210, and a flat key can be inserted into the hole of the matching flange 220, so that the matching flange 220 is connected to the connecting shaft 210.

[0044] Of course, in some other embodiments, the scraper shaft 100 and the connecting flange 130 can be connected by a tapered pin. In detail, the connecting flange 130 can be fixed to the scraper shaft 100 by a tapered pin. Similarly, the matching flange 220 can also be fixed to the connecting shaft 210 by a tapered pin.

[0045] Alternatively, the scraper shaft 100 and the connecting flange 130 may be connected by welding, or the connecting shaft 210 and the matching flange 220 may also be connected by welding.

[0046] In some other embodiments, the scraper shaft 100 can also be interference fit with the connecting flange 130, and the connecting shaft 210 can also be interference fit with the matching flange 220. Alternatively, the scraper shaft 100 can be connected to the connecting flange 130 by bolts, and the connecting shaft 210 can also be connected to the matching flange 220 by bolts.

[0047] Optionally, the connecting flange 130 and the mating flange 220 are detachably connected. It can be understood that since the connecting flange 130 and the mating flange 220 are detachably connected, it is convenient for the user to replace the connecting assembly 200.

[0048] The mating flange 220 is provided with a plurality of mating holes 221 arranged at intervals along its own circumference, and the connecting flange 130 is provided with a plurality of connecting holes 131 arranged at intervals along its own circumference. The plurality of connecting holes 131 are arranged in one-to-one correspondence with the plurality of mating holes 221. In detail, at least one of the mating holes 221 and the connecting holes 131 is a threaded hole, that is, the mating flange 220 is connected to the connecting flange 130 by threaded fasteners, thereby ensuring the connection strength between the connecting flange 130 and the mating flange 220.

[0049] Of course, in some other embodiments, the connecting flange 130 and the matching flange 220 may also be snap-connected together.

[0050] Of course, in some other embodiments, the mating flange 220 and the connecting flange 130 may not be limited to a detachable connection. For example, the connecting flange 130 and the mating flange 220 may also be connected together by welding.

[0051] Among them, a grease port 231 is opened on the outer side of the first bearing seat 230. The grease port 231 is usually called a grease nozzle or a lubrication nozzle. It is mainly an opening in the design of the first bearing seat 230 to facilitate the addition of lubricating oil (such as butter) into the bearing.

[0052] It should be noted that the grease port 231 is generally located on the side or top of the first bearing seat 230. In this embodiment, the grease port 231 is located on the top of the first bearing seat 230, and is mostly in the shape of a round hole or a flat hole, and is equipped with one or more grease nipple joints. When the first bearing 240 needs to be supplemented with grease during the operation of the equipment, the grease can be injected into the first bearing 240 through the grease port 231 through a grease gun or other tools, so as to ensure good lubrication of the first bearing 240, reduce friction, reduce wear, extend the service life of the first bearing 240, and effectively prevent the first bearing 240 from overheating or early failure.

[0053] Optionally, in order to ensure that the scraper shaft 100 in the flotation machine can rotate stably, a second bearing seat 120 and a second bearing 110 are also provided at one end of the scraper shaft 100 close to the connecting member. The second bearing 110 is installed in the second bearing seat 120, and the second bearing seat 120 is located on the side of the connecting member away from the connecting shaft 210.
