Abstract

The invention relates to a cotton grabbing mechanism of a mechanical cotton picking head. The grabbing mechanism consists of a cotton grasping pricker roll (17) and a cotton stripping comb board (2), wherein the cotton grasping pricker roll (17) adopts the structure that nylon yarn bundles (1) are planted on a plastic pipe with a hole in the middle, and the nylon yarn bundles (1) are regularly and annularly distributed on the external surface of the plastic pipe (3); an included angle of 25 degrees is formed between the nylon yarn bundles and the diameter of the section of the plastic pipe, and the nylon yarn bundles (1) incline to the front of the rotation of the cotton grasping pricker roll (17). When the cotton picking head works, the nylon yarn bundles (1) hook cotton into the cotton picking head when the rotating cotton grasping pricker roll (17) is in contact with the cotton. Comb teeth of the cotton stripping comb board (2) are inserted between nylon yarn rings consisting of the nylon yarn bundles adjacent to the cotton grasping pricker roll (17), and the cotton which is grabbed by the cotton grasping pricker roll (17) can be stripped out of the cotton grasping pricker roll (17) to enter a transporting region.

Description

A kind of cotton grasping mechanism of mechanical cotton-picker head

Technical field

The present invention relates to a kind of cotton grasping mechanism of mechanical cotton-picker head, this mechanism completes crawl to cotton and stripping by grabbing cotton licker-in and stripping pecten.

Background technology

Mechanical cotton-picker, especially small-sized efficient cotton picker are the active demands of the numerous cotton growers in cotton production areas, but domestic and international so far do not have substantial breakthrough in small cotton picker, do not have the small cotton picker of mature and reliable to introduce to the market.Consulting after about the various data of cotton picker and patent, there are many reports about mechanical cotton-picker and patent, but respectively have defect and the problem of many technical elements, possibly cannot be committed to practice, up to the present also not having ripe small cotton picker to introduce to the market is exactly well annotate.The patented technology with stronger practicality is that Huang Hui declares " picking apparatus of fully automatic cotton picker ", the patent No.: 200910104749.X, describes the technology contents of this patent, and this picker is very complicated, and it is very accurate, be not suitable for adopting on the farm machinery of land for growing field crops, the part of cotton picking is Saw blade, peels off Saw blade to make cotton, Saw blade also needs to swing, therefore easily damage, not easily change, practicality is poor.Saw blade has sharp tooth cutting edge of a knife or a sword simultaneously, scratches cotton leaf and cotton stalk when plucking, and cotton leaf and cotton stalk can secrete green liquid, pollute cotton.This patented technology adopts helical spring conveying to pluck the cotton arrived, very unreliable.Other technologies in the application problem are more, although therefore technological achievement is delivered and do not tried out for many years.

Summary of the invention

Technical problem to be solved by this invention is practicality and the durability of picker, applies for small cotton picker.For solving the problem.This present invention grabs cotton from harvesting, and cotton peels off from grabbing cotton licker-in, has carried out the aspect such as structural design, material selection and has researched and developed.

The present invention's design is grabbed cotton licker-in and is completed crawl cotton, grabbing cotton licker-in is a plastic tube having centre bore, and plastic tube is implanted with nylon tow, and nylon tow is the distribution of well-regulated round at plastic tube, each circle has 16 bundle nylon yarns, a plastic tube is evenly distributed with 15 circle nylon tow.In order to capture cotton better, the diameter in nylon tow and plastic tube cross section, place has the angle of 25 °, and nylon tow tilts to the front of rotating.Grab cotton licker-in operationally, cotton-picker head rotates, and understands contacting with the cotton being distributed in cotton-picker head surrounding, grab cotton licker-in again in rotation simultaneously under grabbing the effect that cotton licker-in rotates at cotton-picker head, and when therefore touching cotton, nylon tow is hooked to cotton in cotton-picker head.

Grab cotton licker-in cotton to be hooked after cotton-picker head inside, cotton must be stripped down from grabbing cotton licker-in, there is the comb of a stripping pecten to insert for this reason and grab among the cotton gap stinging the adjacent two nylon bundle circles rolled, as comb, the cotton grabbing the crawl of cotton licker-in is stripped down.Grab cotton licker-in like this to coordinate with stripping pecten, complete and capture cotton and peel off cotton.

Accompanying drawing explanation

Below in conjunction with drawings and embodiments, the present invention is described in further detail.

Fig. 2 grabs cotton licker-in and the cooperation figure of stripping pecten when cotton-picker head works.

Fig. 3 is the view of grabbing cotton licker-in.

Fig. 4 is the cross sectional view of cotton picking licker-in.

Fig. 5 is the figure that plants of cotton picking licker-in nylon tow.

Fig. 6 is the front view of stripping pecten.

Fig. 7 is the A direction view of stripping pecten.

Embodiment

Fig. 1 is that the cotton thorn of grabbing of cotton grasping mechanism of the present invention rolls the cooperation figure with stripping pecten.Grabbing nylon tow 1 that cotton licker-in plastic tube 3 planted, nylon tow 1 is that circle one circle is planted on plastic tube 3, is inserted with the comb of stripping pecten 2 in the gap between two adjacent rings nylon tow.

As seen from Figure 2, when the nylon tow 1 of grabbing cotton licker-in touches cotton, owing to grabbing cotton licker-in in rotation, cotton is hooked cotton-picker head by nylon tow 1, owing to there being the comb of stripping pecten 2 to insert between the gap of nylon tow 1, the comb of stripping pecten 2 with grab cotton licker-in and have an angle, rotate along with grabbing cotton licker-in, nylon yarn 1 is restrainted and is forwarded stripping pecten 2 gradually to behind, and cotton is blocked cannot follow nylon tow 1 and continue to rotate, namely by under nylon tow 1 exfoliation.

Can find out, grab cotton thorn roll with adjacent before a stripping pecten 2 form a cotton admission passage, when grabbing cotton licker-in nylon tow 1 and hooking cotton, cotton is subject to the stop of stripping pecten 2 above, cannot move to other directions, have to move downward with nylon tow 1.

Fig. 3 is the view of grabbing cotton licker-in, a-circle-by-a-circle nylon tow that plastic tube 3 has been planted, and there is a through hole 10 at plastic tube center, through hole 10 with grab cotton licker-in axle and coordinate, cotton licker-in will be grabbed and be fixed on cotton picking licker-in axle, rotate with axle.

Fig. 4 is the sectional view of grabbing cotton licker-in, can see that each circle has 16 bundle nylon yarns to form, can find out that nylon tow and base diameter of a circle have an angle simultaneously.

Fig. 5 is the figure that plants of cotton picking licker-in nylon tow, and can find out that nylon tow 1 and diameter of section have the angle of 25 °, nylon tow 1 turns forward.

Fig. 6 is the view of stripping pecten 2, and stripping pecten 2 is fixed on the forward and backward wallboard face of cotton-picker head by two screws 11.

Fig. 7 is the A direction view of stripping pecten 2, can clearly be seen that the comb of stripping pecten.
