Embodiment 1

[0022] Example 1 figure 1 , Figure 4 Shown. The cotton picking spindle of the present invention includes a cotton picking part 1 and a driving part 2. The picking spindle 10 rotates around its axis line, and the driving part 2 is connected with a driving device. The driving part 2 includes a bearing part 15 which is concentric with the longitudinal axis 5 and is supported in a bushing (not shown in the figure) in the spindle lifter. The gear 20 is located at the end of the bearing part 15, and the gear 20 meshes with an auxiliary gear (not shown in the figure) in the spindle picking rod, so that the spindle 10 rotates in the cotton picking direction R around the axis 5. The cotton picking part 1 is provided with at least one continuous spiral groove 3 along the axial direction, and there is a continuous thread protrusion 9 formed by the groove wall of the spiral groove 3. The rotation direction of the thread protrusion 9 is the same as the rotation of the spindle 10 when grabb...

Embodiment 2

[0025] Example 2 such as figure 2 , Image 6 , Figure 7 , Figure 8 Shown. The ingot picking includes a cotton picking part 8 and a driving part. The cotton picking part 8 is provided with at least one continuous spiral groove 6 along the axial direction, and there is a continuous thread protrusion formed by the groove wall of the spiral groove 6. The best range of the helix angle θ of the thread protrusion and the spiral groove 6 is: 10o≤θ≤65o. versus figure 1 The difference is that the cotton picking part 8 is a conical thread; a plurality of hook teeth 7 are provided on the side of the included angle area formed by the side wall and the top surface of the thread protrusion.

[0026] Such as Figure 4 , Figure 5 , Image 6 Shown. The cross-sectional shape of the threaded protrusion can be rectangular, trapezoidal or sawtooth.

Embodiment 3

[0027] Example 3 such as image 3 Shown. The difference from Embodiment 1 is that hook teeth 12 are provided in the spiral groove 11, and no hook teeth are provided on the threaded protrusion 16.

[0028] Such as Picture 9 , Picture 10 Shown. Picture 9 It is a schematic diagram showing that the hook tooth provided by the present invention does not completely destroy the continuity of the top surface of the thread protrusion. Picture 10 It is a schematic diagram of the hook teeth provided in the present invention forming a slit on the top surface where it is located, and at least a part of the slit width γ is less than 1.5 mm.

[0029] In the operation of embodiment 1, the attached gear in the ingot 10 rotates the gear 20 when the cotton is picked, and the gear 20 makes the ingot 10 rotate in the direction R around the axis line 5, when the hook 4 of the threaded protrusion 9 and When cotton sticks, cotton bolls or cotton stalks and other hard objects are in contact, the threa...

Abstract

The invention relates to a cotton-picking spindle, and belongs to the technical field of cotton-picking machines. The cotton-picking spindle mainly solves the problem in a current cotton-picking spindle that the impurity content in picked cotton is increased. The cotton-picking spindle is mainly characterized in that a cotton-picking part is provided with at least one continuous spiral groove along the axial direction and a threaded protrusion, the position in the spiral groove and / or the side wall of the threaded protrusion are provided with hook teeth, and the hook teeth do not rise above the threaded protrusion where the hook teeth are located; the threaded protrusion is continuous, or at least a small part of the slit width of top face of the threaded protrusion is lesser than 1.5 mm; the rotation direction of the threaded protrusion is the same as the rotation direction of the spindle when cotton-picking is carried out. The cotton-picking spindle is mainly used for cotton picking, when the spindle is in contact with hard objects such as cotton branches, cotton bolls or cotton stalks, the piercing depth of the hook teeth is limited by the threaded protrusion, the probability for picking impurities by the spindle is lowered, when the spindle is in contact with the soft and fluffy cotton, the spindle rotates to hook the cotton and winds the cotton onto the spindle-self so that the cotton can be picked off from the cotton bolls, and therefore the impurity content in the picked cotton is greatly lowered.

Description

Technical field [0001] The invention belongs to the technical field of cotton picking machinery, and specifically relates to a cotton picking ingot used for a cotton picking machine. Background technique [0002] The cotton picking ingots in the prior art are provided with diagonal hook teeth on the outer surface of the cotton picking part of the ingot. During picking, the picking ingot rotates the cotton around itself to complete the cotton picking. The diagonal teeth are exposed on the outer surface of the ingot. During work, when picking the cotton, the exposed diagonal teeth and the cotton stalk, bolls, cotton branches, etc. will be caught back together with the cotton and debris, increasing the trash content of the picked cotton. At the same time, the exposed diagonal teeth wear faster, and their service life will be shortened accordingly. In addition, because of the high trash picking rate of this kind of ingot picking, defoliants must be used before cotton picking, which ...
