[0004] The spindle holders of several spindles are connected to the seat tube by threads. However, during the high-intensity cotton picking process, the threaded connection between the spindle holder and the seat tube is prone to loosening, which is not conducive to the stable installation of the spindle on the seat tube. Utility Model Content

[0005] The purpose of this invention is to provide a seat tube assembly based on a cotton harvester, which facilitates the stable installation of the spindle body on the seat tube.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a seat tube assembly based on a cotton harvester, comprising a seat tube body, a drive shaft rotatably connected within the seat tube body, a rocker arm disposed at one end of the seat tube body, and multiple spindle-removing bodies mounted on the seat tube body. The spindle-removing body includes a spindle-removing seat with threads on its surface and a spindle-removing rod rotatably connected within the spindle-removing seat. The seat tube body has threaded holes for threaded connection of the spindle-removing seat. The seat tube body is integrally provided with a boss for opening multiple threaded holes. A hexagonal turntable is integrally provided on the periphery of the spindle-removing seat, abutting against the upper surface of the boss. A limiting sleeve is sleeved on the periphery of the boss for abutting against the side of the hexagonal turntable. Both ends of the limiting sleeve are provided with C-shaped buckles for engaging with the end of the seat tube body. A reinforcing rib is provided between the buckles and the limiting sleeve. When the hexagonal turntable rotates to the position abutting against the upper surface of the boss, the side of the hexagonal turntable is parallel to the side wall of the boss.

[0007] A further feature of this invention is that a dust cover is provided at one end of the spindle removal seat away from the boss, and a sleeve is provided at one end of the dust cover to fit over the outside of the spindle removal seat. Two rubber retaining rings are provided on the inner wall of the sleeve, and a retaining ring groove is provided on the peripheral outer wall of the spindle removal seat for the rubber retaining rings to be inserted.

[0008] A further feature of this invention is that the spindle removal rod includes a base rod passing through the spindle removal seat and a head end detachably connected to the upper end of the base rod.

[0009] A further feature of this invention is that: a slot is provided in the upper end of the base rod, a plug rod is provided at the end of the head end and embedded in the slot, a threaded mounting hole is provided on the inner wall of the slot, a connecting bolt is threaded into the threaded mounting hole, and an annular groove is provided on the periphery of the plug rod for the end of the connecting bolt to be embedded.

[0010] A further feature of this invention is that the inner wall of the dust cover and the bolt head of the connecting bolt are fitted with a clearance.

[0011] A further feature of this invention is that the base rod has an oil injection hole that communicates with the slot and the interior of the seat tube body.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. When the ingot-removing body is threadedly connected to the threaded hole on the boss using the ingot-removing seat with threads on its surface, the ingot-removing seat can be rotated relatively easily by the hexagonal turntable on the periphery of the ingot-removing seat. When the hexagonal turntable rotates to the position where it abuts against the upper surface of the boss, the side of the hexagonal turntable is parallel to the side wall of the boss. Then, the limiting sleeve can be fitted around the boss, and the limiting sleeve is engaged with the end of the seat tube body by the buckle at the end. At this time, the limiting sleeve can abut against the side of the hexagonal turntable, thereby limiting the circumferential rotation of the hexagonal turntable by the limiting sleeve, preventing the hexagonal turntable from automatically deflecting, which ultimately facilitates the stable installation of the ingot-removing body on the seat tube.

[0014] 2. The dust cover can prevent dust from entering the spindle removal base. The dust cover is wrapped around the outside of the spindle removal base and the wrap is secured to the retaining groove on the outer wall of the spindle removal base with a rubber retaining ring. This allows for stable and convenient installation of the dust cover on the spindle removal base.

[0015] 3. The spindle removal rod includes a base rod that passes through the spindle removal seat and a head end that is detachably connected to the upper end of the base rod. When the head end is damaged, only the head end needs to be disassembled and replaced, thus avoiding the need to replace the entire spindle removal body and ultimately saving maintenance costs.

[0016] 4. When it is necessary to disassemble the head end, simply unscrew the connecting bolt in the threaded mounting hole, and then pull the insert rod out of the slot, thereby achieving convenient disassembly and assembly of the head end on the base rod;

[0017] 5. By utilizing the clearance fit between the inner wall of the dust cover and the bolt head of the connecting bolt, the dust cover can limit the connecting bolt in the threaded mounting hole, preventing the connecting bolt from automatically coming out of the threaded mounting hole; when it is necessary to disassemble the connecting bolt, the dust cover must first be removed from the mounting bracket before the connecting bolt can be screwed on, thus ensuring the stable threaded connection of the connecting bolt.

[0018] 6. When it is necessary to periodically inject lubricating oil into the body of the seat tube, the oil injection hole opened in the base rod is connected to the slot and the inside of the seat tube body. After removing the head end, the insert rod can be pulled out of the slot, and then lubricating oil can be injected into the oil injection hole. There is no need to remove the spindle body, thus ensuring the stable fixation of the spindle body on the seat tube body. Attached Figure Description
