Technical Field
[0001] The present application relates to the technical field of gear shafts, and in particular to a gear shaft of a pruning machine coupling. Background Art
[0002] A pruning machine gear shaft refers to the shaft that carries the gears in a pruning machine (also called a pruning saw or pruner). A pruning machine is a piece of equipment used to prune trees, trim bushes, and trim plants. It is usually driven by a gear system. The gear shaft is one of the core components of the pruning machine gear transmission system. It carries the gears and realizes the shearing action of the pruning machine through the rotation of the gears.
[0003] However, the existing gear shaft can be more stable during use and more convenient during the overall maintenance process, and there is no need to apply oil to the bearing separately. A Chinese patent (Announcement No.: CN 220726827 U) discloses a pruning machine coupling gear shaft, which is sleeved with butter on the outside of the shaft body so that the butter can move downward under the action of centrifugal force on the outside of the shaft body when the shaft body rotates. When the above document does not have a blocking component, when the butter moves downward for oiling, because the other end of the shaft body is fixed with a gear, the butter will contact the gear when it continues to move, and the butter is easy to get stuck on the teeth of the gear, thereby affecting the meshing transmission of the gear and other components.

DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0031] See also Figure 1-2 In this embodiment, a pruning machine coupling gear shaft includes a gear shaft body 1, an oil storage chamber 2 is provided inside the gear shaft body 1, an oiling component for applying lubricating oil to the outside of the gear shaft body 1 is provided at the top of the inner cavity of the oil storage chamber 2, and a supplementary structure for supplementing lubricating oil inside the oil storage chamber 2 is provided on the right side of the top of the inner cavity of the oil storage chamber 2.
[0032] See also Figure 1 , Figure 3 , Figure 4The oiling assembly in this embodiment includes a blocking block 31, two limiting rods 34, an oil-slinging block 32 fixedly installed at the lower end of the blocking block 31, a support plate 33 fixedly installed at the lower end of the oil-slinging block 32, an anti-drop block 35 fixedly installed at the lower end of the limiting rod 34, and a pushing structure fixedly installed at the left and right ends of the support plate 33 for pushing it to reset.
[0033] Among them, an oil outlet hole is opened at the top of the gear shaft body 1, and the oil outlet hole is connected with the oil storage chamber 2. The oil outlet hole is T-shaped, and the blocking block 31 and the oil throwing block 32 are slidably connected to the inner side of the oil outlet hole, so that the blocking block 31 and the oil throwing block 32 can be moved out or moved to the oil storage chamber 2 through the oil outlet hole, so that the lubricating oil in the oil storage chamber 2 can flow out of the gear shaft body 1 through the oil outlet hole.
[0034] In addition, a plurality of oil outlets are provided around the outer surface of the oil-slinging block 32. The oil-slinging block 32 is in the shape of a cylinder with a hollow interior and a missing lower end, so that the lubricating oil in the oil storage chamber 2 can flow into the oil-slinging block 32. When the oil-slinging block 32 is moved out of the interior of the gear shaft body 1, the lubricating oil can flow out of the interior of the oil-slinging block 32 through the oil outlet. When the gear shaft body 1 performs a circular motion, the oil-slinging block 32 will be thrown out of the interior of the gear shaft body 1 due to the centrifugal force of the circular motion, and it can also rotate, so that the outflowing lubricating oil can be splashed on the outside of the gear shaft body 1, and the lubricating oil can also splash onto other components such as gears.
[0035] At the same time, the top ends of the two limiting rods 34 are fixed to the top end of the inner cavity of the oil storage chamber 2, and two connecting holes are opened at the top end of the support plate 33. The limiting rods 34 are slidably connected to the inner side of the connecting holes, so that the support plate 33 can slide on the outer surface of the two limiting rods 34, so as to prevent the oil throwing block 32 from falling off from the inside of the gear shaft body 1 due to the action of centrifugal force. The support plate 33 is an annular plate to avoid affecting the lubricating oil from entering the oil throwing block 32.
[0036] See also Figure 3 The pushing structure in this embodiment includes two vertical rods 38, two pushing springs 39, two pulling rods 36, and a squeezing block 37 hingedly connected to the opposite ends of the two pulling rods 36 for squeezing the pushing springs 39. The pushing springs 39 are sleeved on the outer surfaces of the vertical rods 38, and the squeezing blocks 37 are slidably connected to the outer surfaces of the vertical rods 38. The other ends of the two pulling rods 36 are hingedly connected to the left and right ends of the support plate 33. When the oil-slinging block 32 moves, the support plate 33 can pull the two pulling rods 36 to pull the squeezing blocks 37 to move.
[0037] At the same time, circular holes are opened at the top ends of the two extrusion blocks 37, and the vertical rod 38 is slidably connected to the inner side of the circular holes. The vertical rod 38 is a T-shaped rod, so that the extrusion block 37 can slide on the outer surface of the vertical rod 38, and the diameter of the circular hole is smaller than the diameter of the lower end of the vertical rod 38, which can prevent the extrusion block 37 from falling off the outer surface of the vertical rod 38.
[0038] See also Figure 1 , Figure 2 and Figure 5 The supplementary structure in this embodiment includes a blocking block 311, an operating block 310 fixedly installed at the top of the blocking block 311 for the operator to rotate, and a sealing block 312 fixedly installed at the lower end of the blocking block 311, so as to enhance the sealing performance of the blocking block 311 when blocked.
[0039] Secondly, a supplementary hole is opened on the right side of the top end of the gear shaft body 1, and the supplementary hole is connected to the oil storage chamber 2. The blocking block 311 is threadedly connected to the inner side of the supplementary hole, so that the staff can remove the blocking block 311 from the supplementary hole so as to supplement the lubricating oil from the oil storage chamber 2 of the gear shaft body 1 through the supplementary hole.
[0040] The working principle of the above embodiment is:
[0041] During use, when the gear shaft body 1 is rotating, the blocking block 31 and the oil throwing block 32 are subjected to centrifugal force, and due to the action of the centrifugal force, the blocking block 31 and the oil throwing block 32 are sequentially moved out of the oil outlet hole of the gear shaft body 1. When the oil throwing block 32 moves, the two pulling rods 36 are pulled by the support plate 33 to move, so that the pulling rod 36 pulls the extrusion block 37 to move, so that the extrusion block 37 can squeeze the push spring 39. At the same time, the multiple oil outlets on the outer surface of the oil throwing block 32 are retained outside the gear shaft body 1, so that the lubricating oil in the oil storage chamber 2 of the gear shaft body 1 flows into the oil throwing block 32. The oil is poured into the gear shaft body 1 and flows out of the oil-slinging block 32 through the oil outlet, so that the gear shaft body 1 can drive the oil-slinging block 32 to rotate when rotating, and the oil-slinging block 32 can drive the lubricating oil flowing out of the multiple oil outlets to rotate, so that the lubricating oil splashes on the outside of the gear shaft body 1, thereby lubricating the outside of the gear shaft body 1, and the lubricating oil can splash onto other parts such as gears due to inertia and centrifugal force, so as to lubricate the gears and other parts, which can effectively increase the scope of use and prevent the grease from getting stuck in the teeth of the gear and affecting its normal operation;
[0042] When it is necessary to add lubricating oil to the oil storage chamber 2, the operating block 310 drives the blocking block 311 to rotate, so that the blocking block 311 can gradually be disengaged from the supplementary hole of the gear shaft body 1. When the blocking block 311 moves, the sealing block 312 can also be moved out, that is, the staff can add lubricating oil to the oil storage chamber 2 through the supplementary hole.
