Description

Technical Field

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

[0002] The picking spindles currently used in cotton pickers are integrally formed and installed on a rotating frame. When picking cotton, the cotton will be entangled on the high-speed rotating picking spindles, and then the cotton will be separated from the picking spindles by a cotton removing device.

[0003] The shortcomings of existing picking ingots are:

[0004] When the cotton picker is operating in the field, the picking spindles rotate at high speed and the cotton in the cotton bolls is hooked by the cotton picking teeth on the surface of the picking spindle head. This contact operation method will cause the picking spindle head to wear easily. Therefore, the picking spindle head is a wearing part and needs to be replaced as needed. The integrated picking spindle structure can only replace the picking spindle as a whole, and the picking spindle head cannot be replaced individually, which affects production efficiency and increases production costs.

[0009] The picking rod comprises a positioning rod portion, an inverted cone fixing portion and a picking head which are arranged in sequence from top to bottom, the positioning rod portion is inserted into the positioning blind hole, and the picking head is evenly provided with at least two groups of cotton picking teeth in the circumferential direction;

[0010] The inner hole of the fixing sleeve includes a tapered hole portion corresponding to the inverted tapered fixing portion. The fixing sleeve is sleeved outside the spindle picking rod. The fixing sleeve and the connecting seat are threadedly connected. The inverted tapered fixing portion and the tapered hole portion are locked and fixed.

[0011] Furthermore, two shaft sleeves are arranged in sequence from top to bottom between the connecting seat and the connecting sleeve, and a gap is left between the two shaft sleeves.

[0012] Furthermore, the inner hole of the fixing sleeve also includes a threaded hole portion, and the lower portion of the connecting seat is provided with an external threaded portion, and the external threaded portion and the threaded hole portion are threadedly connected.

[0013] Furthermore, the outer surface of the fixing sleeve is rolled with patterns.

[0014] Furthermore, the spindle picking rod is provided with a transition portion between the inverted cone-shaped fixing portion and the spindle picking head, and a convex rib is axially provided on the circumferential surface of the transition portion.

[0015] Furthermore, the picking spindle head is axially provided with reinforcing ribs between two adjacent groups of cotton picking teeth.

[0016] Furthermore, the limiting sleeve and the connecting seat are interference fitted.

[0017] Furthermore, the gear is a bevel gear.

[0018] Compared with the prior art, the cotton picking machine spindle of the utility model has the following advantages:

[0019] (1) In the utility model, the spindle picking rod and the connecting seat are detachably connected through a fixing sleeve, which improves the convenience of the spindle picking rod, which is a vulnerable part, improves efficiency, and reduces costs.

[0020] (2) In the utility model, the fixing sleeve and the spindle picking rod are locked and fixed by a wedge-shaped structure formed between the tapered hole and the inverted tapered fixing portion, thereby improving the operating stability of the spindle picking rod.

[0021] (3) In the present invention, the arrangement of the reinforcing ribs on the transition portion of the picking rod and the picking head improves the strength of the picking rod itself, reduces the possibility of its deformation to a certain extent, and ensures the stability of the picking operation of the cotton picker.

DETAILED DESCRIPTION

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] like Figure 1 As shown, a cotton picker spindle comprises a connecting seat 1 and a spindle picking rod 5. The top of the spindle picking rod 5 is inserted into the connecting seat 1, and the fixing sleeve 6 connects and fixes the connecting seat 1 and the spindle picking rod 5. A conical gear 11 is provided on the top of the connecting seat 1, and a limiting sleeve 4 is fitted in the middle and lower parts. A connecting sleeve 2 is sleeved on the outside of the connecting seat 1, and the connecting sleeve 2 is located between the limiting sleeve 4 and the gear 11. Two shaft sleeves 3 are arranged in sequence from top to bottom between the connecting seat 1 and the connecting sleeve 2, and a gap is left between the two shaft sleeves 3. The connecting seat 1 can rotate relative to the shaft sleeve 3. This structure is a common structure of cotton picker spindle picking and will not be described in detail here.
