Description

Technical Field

[0001] The invention relates to the field of cotton picking, in particular to a detachable spiral bevel gear picking spindle. Background Art

[0002] As the core component of the horizontal spindle-type cotton picker, the working condition of the spindle is crucial to the quality of cotton picking. The spindle gears of existing spindles generally use conventional bevel gears, which are prone to cause spindle circular runout and large coaxiality errors, resulting in the phenomenon of "shaking head and tail" under the transmission clearance and wear of the cotton picker spindle. At the same time, for the spindles with a high damage rate in the cotton picker, the integrated spindle structure on the market is not conducive to the replacement of parts after wear, resulting in reduced cotton picking efficiency and increased replacement costs.

[0003] Based on the above description, and searching for an application number: CN 204907187 U provides a cotton picker spindle, whose spindle head and spindle connecting rod are threadedly connected, but when picking cotton and removing cotton, there is a risk of separation of the spindle head and the spindle connecting rod under high-speed rotation with the threaded connection; and another patent CN 214676633 U provides a combined cotton picker spindle assembly, which uses a thread plus a snap method to fix the bevel gear, the spindle rod and the spindle head, but the spindle structure is complex and involves the connection and fixation of multiple parts, which not only increases the damage rate of the spindle, but also increases the difficulty of replacing the spindle. Summary of the invention

[0004] In order to solve the technical problems that the gears of the existing cotton picker spindles vibrate during the working process, the transmission stability is poor, the integrated structure of the spindles makes it difficult to replace during use, and the practicality is low.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a detachable spiral bevel gear spindle picking, comprising a spindle picking gear, a square guide hole, a spindle picking rod, a spindle picking head, a connecting rod segment, a square joint, a threaded hole, and a hexagon socket head screw. The spindle picking gear is provided with a square guide hole, the spindle picking rod is divided into a spindle picking head and a connecting rod segment, a square joint is provided at the end of the connecting rod segment, and a threaded hole is provided inside the square joint.

[0006] Preferably, the spindle picking gear adopts a spiral bevel gear.

[0007] Preferably, the square joint at the end of the connecting rod segment and the square guide hole on the spindle picking gear adopt a transition fit.

[0008] Preferably, the spindle picking gear and the spindle picking rod are fixedly connected by means of a hexagon socket head screw.

[0009] Beneficial effects obtained by the present invention:

[0010] 1. The present invention provides a detachable spiral bevel gear picking spindle, which uses a spiral bevel gear as a picking spindle gear to increase the gear meshing degree, reduce vibration, and ensure smooth transmission and wear resistance.

[0011] 2. The present invention achieves high connection strength and large torque by matching the square joint at the end of the connecting rod segment with the square guide hole on the spindle picking gear, thereby ensuring the rotation stability of the spindle picking during high-speed rotation. At the same time, the spindle picking gear and the spindle picking rod are fixedly connected by hexagon socket head screws, which facilitates the replacement of the spindle picking and improves the practicality of the present invention.

[0017] See also Figures 1 to 4 The present invention provides a technical solution: a detachable spiral bevel gear picking spindle, a picking spindle gear 1, a square guide hole 101, a picking spindle rod 2, a picking spindle head 201, a connecting rod segment 202, a square joint 203, a threaded hole 204, and a hexagon socket head screw 3. The picking spindle gear 1 is provided with a square guide hole 101, the picking spindle rod 2 is divided into a picking spindle head 201 and a connecting rod segment 202, a square joint 203 is provided at the end of the connecting rod segment 202, and a threaded hole 204 is opened inside the square joint 203.

[0018] In this embodiment, the spindle gear 1 is a spiral bevel gear.

[0019] In this embodiment, the square joint 203 at the end of the connecting rod segment 202 and the square guide hole 101 on the spindle gear 1 adopt a transition fit, which improves the connection strength and transmission torque between the spindle gear 1 and the spindle rod 2, and ensures the rotation stability when the spindle rotates at high speed.

[0020] In this embodiment, the spindle picking gear 1 is fixedly connected to the spindle picking rod 2 by means of a hexagon socket head screw 3, so as to facilitate the replacement of the spindles, improve the cotton picking efficiency and reduce the cost.

[0021] Working principle of the present invention: When in use, first insert the square joint 203 at the end of the connecting rod section 202 into the square guide hole 101 on the spindle picking gear 1, and then use the hexagon socket head screw 3 to cooperate with the threaded hole 204 inside the square joint 203 to fix the spindle picking gear 1 and the spindle picking rod 2. When the spindle picking rod 2 needs to be replaced, the hexagon socket head screw 3 is rotated in the opposite direction to separate the hexagon socket head screw 3 from the threaded hole 204, and then the spindle picking rod 2 is pulled out from the square guide hole 101 for replacement.
