Description

Novel cotton seed delinting machine for breeding

Technical Field

The utility model relates to a cotton breeding, planting technical field, concretely relates to breeding is with novel cotton seed delinter.

Background

The cotton seed surface remains a layer of short fiber after cotton ginning by the cotton ginning machine, the short fiber on the surface of the cotton seed is removed in order to remove various germs on the seed short fiber, the seedling disease is prevented, the mutual attachment condition among the seeds is lightened, the maturity of the seeds is clearly visible from the surface, the mechanical and manual selection is convenient, and the mechanical seeding is also convenient. The common cotton seed delinting method mainly comprises two types of chemical delinting and mechanical delinting, and a sulfuric acid delinting method in chemical delinting is mostly adopted in the prior art for delinting, but the procedure is complicated, repeated scrubbing and washing are needed, the seed quality is influenced if the washing is not clean, and certain problems of operation danger and environmental pollution exist due to sulfuric acid; the existing mechanical delinting equipment has the problems of incomplete delinting, high cottonseed breakage rate and the like.

Disclosure of Invention

To the not enough of above-mentioned prior art existence, the utility model aims at providing a novel cotton seed takes off fine hair machine is used in breeding that structural design is reasonable, broken seed rate is low.

In order to achieve the above object, the utility model adopts the following technical scheme: a novel cotton seed delinting machine for breeding comprises a delinting barrel and is characterized in that the barrel wall of the delinting barrel is a hollow interlayer wall, a plurality of cotton velvet discharge ports are formed in the inner layer wall of the hollow interlayer wall, a negative pressure suction port communicated with the hollow part of the barrel wall is fixed at the bottom of one side of the delinting barrel, and the negative pressure suction port is connected with a negative pressure exhaust fan through a corrugated pipe; a rotary motor is fixed at the top of the delinting barrel, an output shaft of the rotary motor penetrates through the top of the delinting barrel and is fixedly connected with a driving gear, the driving gear is positioned in the delinting barrel, a driving delinting piece which extends vertically downwards is fixed at the center of the driving gear, and the top of the driving delinting piece is in rotary fit with a bearing disc through a bearing and a bearing seat; the driving gear is meshed with at least four driven gears, each driven gear is meshed with a third gear, driven delinting pieces which extend vertically downwards are fixed at the centers of each driven gear and each third gear, and the top of each driven delinting piece is in rotary fit with the bearing disc through a bearing and a bearing seat; the driving delinting piece and the driven delinting pieces are both composed of a support shaft and steel wire brushes wrapped on the periphery of the support shaft, and distances are reserved between the steel wire brushes of two adjacent driven delinting pieces and between the driving delinting piece and the steel wire brushes between the adjacent driven delinting pieces.

Furthermore, the distance between the driven delinting piece positioned at the outermost periphery of the bearing disc and the inner wall of the delinting barrel is not more than 2 cottonseed diameter sums.

Compared with the prior art, the utility model discloses the beneficial effect who possesses is:

(1) by adopting the mode of the utility model, the cotton seeds are delinted by reversely dragging between two adjacent driven delinting pieces or between the driving delinting piece and the adjacent driven delinting piece, and the cotton seeds are not extruded in the delinting process, so that the breakage rate of the cotton seeds is low;

(2) the wall of the delinting barrel is designed into a hollow interlayer wall, the inner wall of the delinting barrel is provided with holes, and the removed short-staple barrel is sucked out of the delinting barrel periodically under the action of negative pressure, so that the separation of fluff and seeds is realized.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings.

As shown in fig. 1-2, the novel cotton seed delinting machine for breeding of the utility model comprises a delinting barrel 1, wherein the barrel wall of the delinting barrel 1 is a hollow interlayer wall, a plurality of cotton velvet discharge ports are arranged on the inner layer wall of the hollow interlayer wall, a negative pressure suction port 2 communicated with the hollow part of the barrel wall of the delinting barrel 1 is welded and fixed at the bottom of one side of the delinting barrel 1, and the negative pressure suction port 2 is connected with a negative pressure exhaust fan in a threaded connection mode through a corrugated pipe; the top of the delinting barrel 1 is fixed with a rotating motor 3 through a bolt, an output shaft of the rotating motor 3 penetrates through the top of the delinting barrel 1 and then is fixedly connected with a driving gear 4 in a welding manner, the driving gear 4 is positioned in the delinting barrel 1, a driving delinting piece 5 which extends vertically and downwards is fixed at the center of the driving gear 4 through a bolt, the top of the driving delinting piece 5 is in rotating fit with a bearing plate 6 through a bearing and a bearing seat, and the bearing plate 6 is limited through a boss which is fixed on the inner wall of the delinting barrel in a welding manner; at least four driven gears 7 are meshed on the driving gear 4, a third gear 8 is meshed on each driven gear 7, driven delinting pieces 9 which vertically extend downwards are fixed at the centers of each driven gear 7 and each third gear 8 through bolts, and the top of each driven delinting piece 9 is in rotary fit with the bearing disc 6 through a bearing and a bearing seat; the driving delinting piece 5 and the driven delinting piece 9 are both composed of a support shaft and steel wire brushes wrapped on the periphery of the support shaft, wherein a distance (a distance larger than the diameter of one cotton seed but smaller than the diameter of 2 cotton seeds) is formed between the steel wire brushes of two adjacent driven delinting pieces 9 and between the driving delinting piece 5 and the steel wire brushes of the adjacent driven delinting pieces 9.

The utility model discloses the interval that is located between the driven delinting piece 9 of bearing dish 6 outermost periphery and the 1 inner wall of delinting bucket is not more than 2 cottonseed diameters total (enlarge the interval for the demonstration in the figure). The top of the delinting barrel is open, the rotating motor of the delinting barrel is fixed by a bracket welded on the top of the delinting barrel, and cotton seeds to be delinted enter the delinting barrel through a feed port 10 (the feed port is arranged on the bearing plate 6). During operation, drive the driving gear through rotating electrical machines 3, drive driven gear, third gear then, through the meshing antiport between the gear, drive the corresponding piece that takes off the fine hair and pull the fine hair in the reverse direction, the desorption short hair is effectual. According to the practice, a wooden stick is manually inserted from the inlet to agitate or push the seeds to be delinted between the delinting members.
