Description

Technical Field

[0001] The utility model belongs to the field of accessories for cotton pickers, in particular to a cotton picker spindle connection structure. Background Art

[0002] Cotton planted on a large scale is picked by a cotton picker, and its key component is the spindle. Multiple spindle seat tubes are installed on the cotton picker, and multiple spindles are installed on each spindle seat tube. The bevel gear at the end of the spindle is meshed with the driving wheel on the rotating shaft inside the spindle seat tube, and the picking rod of the spindle is arranged through the spindle seat tube, and the cotton on the cotton rod is removed by the rotation of the spindle.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] As shown in the figure, a cotton picker spindle connecting structure includes a spindle 9 seat tube 1 with a plane structure at the bottom, a plurality of mounting grooves 11 are arranged side by side at the bottom of the spindle 9 seat tube 1, a connecting seat 2 is abutted at each mounting groove 11, and a spindle 9 is provided on each connecting seat 2, two connecting rails 3 are relatively fixedly connected to the bottom of each mounting groove 11, and a connecting bar 4 is clamped in each connecting rail 3, the connecting bar 4 is tightly pressed against the bottom of the corresponding connecting seat 2, and the front ends of the plurality of connecting bars 4 extend out of the connecting rails 3 and are commonly fixed to the bottom of the spindle 9 seat tube 1 through a fixing bar 5. In this embodiment, a plurality of mounting grooves 11 are provided at the bottom of the seat tube 1 of the picking spindle 9, and the connecting seat 2 connected with the picking spindle 9 is abutted against the mounting grooves 11 one by one through the cooperation of the connecting rail 3 and the connecting bar 4, and then the plurality of connecting bars 4 are fixed to the bottom of the seat tube 1 of the picking spindle 9 through the fixing bar 5. When the picking spindle 9 needs to be replaced (the picking teeth on the picking spindle 9 are not drawn in the figure), it is only necessary to remove the picking spindle 9 separately, and there is no need to completely disassemble the seat tube 1 of the picking spindle 9. At the same time, the use of screws is greatly reduced, which facilitates disassembly and assembly while ensuring the installation stability, and effectively improves the operating efficiency.

[0029] A rotating shaft 6 is horizontally arranged inside the spindle 9 seat tube 1, one end of the rotating shaft 6 is fixedly connected to the output shaft of the motor 7 fixedly connected to the outside of the spindle 9 seat tube 1, and the other end is connected to the inner wall of the spindle 9 seat tube 1 through a bearing, and a driving wheel 8 meshing with the bevel gear 91 is fixedly connected to the rotating shaft 6 at the bevel gear 91 at the top of each spindle 9. In this embodiment, the driving wheel 8 is also a bevel gear 91, and the rotating shaft 6 is driven by the motor 7 to rotate, which drives the driving wheel 8 to rotate, and drives the spindle 9 to rotate.

[0030] A limiting convex edge 12 is arranged around the upper part of the inner wall of the installation groove 11, and the top is flush with the inside of the seat tube 1 of the picking spindle 9. The cross-section of the connecting seat 2 is a convex structure, the upper part is embedded in the limiting convex edge 12, and the lower edge is embedded in the installation groove 11 and abuts against the bottom of the limiting convex edge 12. This arrangement is conducive to positioning the connecting seat 2.

[0031] The connecting rail 3 includes a first vertical section 31, a first horizontal section 32, and a second vertical section 33. The first vertical section 31 and the second vertical section 33 are vertically arranged on both sides of the first horizontal section 32, and the first vertical section 31 is located outside the second vertical section 33 and fixed to the bottom of the spindle 9 seat tube 1.

The fixing bar 5 abuts against the bottom of the front end of the second horizontal section 42 of the connecting bar 4, and the rear side wall abuts against the third horizontal section. The fixing bar 5 is fixedly connected to the spindle picking 9 seat tube 1 at both ends by screws to further enhance the installation stability.

[0033] A groove 51 matching the front end of the second horizontal section 42 is provided at the upper side of the fixing bar 5 corresponding to the front end of each second horizontal section 42. The front ends of the second horizontal sections 42 are embedded in the corresponding grooves 51. The fixing bar 5 limits the connecting bar 4 while making the upper surface of the fixing bar 5 abut against the bottom of the seat tube 1 of the picking spindle 9. After the two ends of the fixing bar 5 are fixed to the bottom of the seat tube 1 of the picking spindle 9 by screws, the connection stability of the connecting bar 4 is improved, thereby ensuring the installation stability of the connecting seat 2.

[0034] A connecting hole is provided in the middle of the connecting seat 2, and a bearing seat 21 is fixedly connected to the connecting hole at the bottom of the connecting seat 2.
