Problems solved by technology

The existing cotton picking machines on the market are often costly and expensive, and the picked cotton has many impurities and many omissions.
In addition, cotton entanglement often occurs in the collecting heads of existing cotton picking machines, and in severe cases, the cotton picking machine jams, and it is often necessary to stop and manually remove the wrapped cotton fibers on the collecting heads, which greatly affects the work efficiency.

Embodiment 1

[0063] The collection head 4 includes 4 groups of hooking sheets, and each group of hooking sheets is provided with 9 sawtooths on the outer edge, that is, m'=4, m=9;

[0064] The separator 6 is 5 groups of separation wheels, each group of separation wheels is provided with 5 blades, that is, n'=5, n=5;

[0065] The speed of the separator is twice the speed of the collection head, that is, k=2.

[0066] Figure 6 The separator shape of a preferred embodiment of the present invention is shown.

[0067] Such as Figure 6 As shown, the blades 62 of the separator 6 are arranged in an arc shape bent in a direction opposite to the direction of rotation of the separator. The blades 62 of the separator 6 are arranged in a curved arc shape, so that the cotton fibers on the blades can be better shaken off by the action of centrifugal force, and the probability of silk entanglement in the separator is greatly reduced.

Embodiment 2

[0069] The collection head includes 6 sets of cotton hooks, and each set of cotton hooks has 6 sawtooths on the outer edge, that is, m'=6, m=6;

[0070] The separator is 7 sets of separation wheels, each set of separation wheels is provided with 3 or 4 blades, that is, n'=7, n=3 or 4, and the blades are arranged in a straight line;

[0071] The rotating speed of the separator is 3 times of the collecting head rotating speed, namely k=3.

Embodiment 3

[0073] Figure 7 It shows the shape of the hooking sheet of the collection head in a preferred embodiment of the present invention.

[0074] Such as Figure 7 As shown, the shape of the sawtooth 42 on the snagging piece 41 of the collection head 4 in this embodiment is preferably formed approximately at a right angle, and the angle range of the right angle is 90±5°.

[0075] More preferably, the right-angled sawtooth is a right angle inclined towards the rotation direction of the collection head, as shown in the figure, that is, the short side of the right angle is on the side facing the rotation direction of the collection head, and the short side of the right angle is adjacent to the previous right angle The long side is also formed as an approximate right angle, and the angle range of the right angle is 90±5°.

[0076] Such a configuration of the sawtooth can make it easier for the hook piece of the collection head to hook the cotton, significantly improve the success rat...

Abstract

The invention discloses a hand-hold type cotton picker, which comprises an outer casing (1), a handle (2), a collecting bag joint (3), a picking head (4), a transmission system (5) and a separator (6), wherein the outer casing (1) is limited with a cotton picking passage, the picked cotton enters the collecting bag joint through the cotton picking passage, the handle (2) is arranged at the upper part of the outer casing (1), the collecting bag joint (3) is arranged at the bottom of the outlet end of the cotton picking passage limited by the outer casing (1) and is used for connecting the cotton picking passage with a collecting bag, the picking head (4) is arranged at the lower side of the inlet end of the outer casing (1) and is used for picking the cotton into the cotton picking passage of the outer casing (1) through the rotating movement, the transmission system (5) is connected with the picking head (4) and the separator (6), and is used for providing power to drive the picking head (4) and the separator (6), and the separator (6) is arranged at the back of the picking head (4) in the outer casing (1) and is used for separating and conveying the cotton on the picking head (4) to the collecting bag joint (3) through the rotating movement. The cotton picker has the advantages that the cotton separating efficiency is improved through the matching of the picking head and a separating wheel, and the labor efficiency of the cotton picking in unit time is improved.

Description

technical field [0001] The invention belongs to the technical field of small agricultural machinery and relates to a hand-held cotton picker. Background technique [0002] Every year there is a bumper cotton harvest, and a large number of cotton pickers from all over the country go to the main cotton producing areas (such as Xinjiang) to pick cotton. Although this increases employment opportunities, manual cotton picking is inefficient, labor-intensive, requires many people, and is labor-intensive and time-consuming. , It often delays the farming season, and due to the large flow of people, it also brings certain pressure to the transportation and other departments. Therefore, it is necessary to design a machine that can replace manual cotton picking to reduce heavy manual labor and improve labor efficiency to meet the social development requirements of agricultural mechanization. [0003] Due to the characteristics of the growth structure of cotton, until now, the picking ...
