Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural product detection, and in particular relates to a drum-type cotton fiber length measuring device. Background Art

[0002] The fiber length of cotton is one of the important physical parameters of the intrinsic quality of raw cotton. The length of cotton fibers not only affects the processing technology and use value, but also affects the cotton drop rate of spinning, which is closely related to the production cost of the enterprise. Cotton fiber length is also an important indicator of cotton breeding. The current mainstream detection method is to use large-scale fiber detection instruments (such as H IV1000 and MF100 cotton fiber quality testers produced by Uster Company of Switzerland, and XJ128A and XJ128pro rapid cotton fiber performance testers produced by Changling Textile Electric) for determination. After stabilization in a laboratory at an ambient temperature of 20±2℃ and a relative humidity of 65±3%RH for 24 hours, random sampling and repeated testing of a batch or part of cotton fibers are carried out. This method is more suitable for quality evaluation of large batches of cotton fiber samples. The detection cycle is long (≥24 hours) and the cost is high; however, in the breeding stage of cotton varieties, if breeders want to quickly understand the cotton fiber length of a certain variety in the field, they must conduct rapid testing in the field. The traditional method of measuring the length of cotton fiber is to pick a cotton flower that has opened its bolls, take a seed with cotton wool from it, comb it neatly with a small comb, place it on a black flannel board, and then use a ruler to measure the length of the cotton fiber, or directly place it on a ruler to measure the length of the cotton fiber. This method is not only inaccurate, but also inefficient and slow to detect. Patent CN204854504U provides a cotton fiber length measuring ruler with a seed spoon. When in use, the thumb of one hand presses the cotton seeds into the seed spoon, fixes the other end of the cotton with a lock and a movable cover, and the other hand slides the movable cover to measure. Although this patent can measure the length of cotton lint, there will be a certain error when the seeds are stuck into the seed spoon due to the lack of a limit device; Patent CN207991408U discloses a cotton combing board with a cotton lint length measurement function. When measuring the length of cotton lint, the cotton seeds are inserted into the cotton holes, the combed cotton is spread flat on the main board, and then the length measuring instrument is moved to measure the length of cotton lint. Although this invention can detect multiple cotton fiber samples at a time, the cotton lint must be combed neatly in advance, otherwise the true length of the cotton lint cannot be measured; Patents CN216694732U and CN211601796U both adopt the order of combing first and then measuring, and still need to comb the cotton lint first and then measure, which greatly reduces the practicality of the equipment.

[0024] As described above, when using the drum shell 3, drum body 14 and brush 15 provided by the utility model, cotton seeds are set on the drum body 14, and the drum body 14 is rotated to drive the cotton fibers on the cotton seeds to fit on the outer wall of the drum body 14 around the axis. In this process, the brush 15 is used to comb the passing cotton fibers.

[0025] In the present utility model, combined with Figure 2 and Figure 6 As shown, a limiting member for limiting the cotton seeds is also installed on the inner side of the drum body 14 of this embodiment, and an opening 13 connected to the limiting member is penetrated through the drum body 14 in the axial direction, and the width of the opening 13 is smaller than the length of the cotton seeds at the narrowest position, and one end of the cotton fiber extends through the opening 13 into the detection area.

[0026] Combination Figure 6 As shown, the limiting member includes a cotton seed holder 11, which is a U-shaped structure. The cotton seed holder 11 is arranged on the inner side of the opening 13, and the two ends of the cotton seed holder 11 are bent to form a mounting portion that fits the inner wall of the drum body 14, and the mounting portion is provided with a rivet 12 that is riveted to the drum body 14.

[0027] As described above, when using the limiter provided by the utility model, the cotton seeds are restricted in the drum body 14 by the limiter, and the cotton fibers on the cotton seeds enter the detection area from the drum body 14 through the opening 13. When the drum body 14 rotates, it is convenient for the cotton fibers to be combed on the outer wall of the drum body 14 by the brush 15, and the cotton seed holder 11 is fixedly mounted on the drum body 14 by the rivet 12.

[0028] Further, in order to facilitate the length measurement of the combed cotton fibers, refer to Figure 1-2 As shown, the outer wall of the drum body 14 is also provided with scale lines 16 for length measurement in the radial direction, and the initial section of the scale lines 16 extends into the opening 13. When the cotton fibers are combed on the outer wall of the drum body 14 by the brush 15, the combed cotton fibers are measured by the scale lines 16.

[0029] Further, in order to facilitate the placement of cotton seeds in the cotton seed holder 11, refer to Figure 1 and Figure 3-5As shown, a side plate 6 is also installed at the end of the drum shell 3, and a notch 10 connected to the detection area is opened on the side plate 6, and the cotton seed holder 11 rotates through the notch 10 based on the rotation. When the cotton seed holder 11 is in the notch 10, it is convenient to place cotton seeds in the cotton seed holder 11 from the outside, and at the same time, the cotton fibers on the cotton seeds enter the detection area through the opening 13. When the drum body 14 is rotated, it is convenient to drive the cotton fibers to be rotated and combed on the outer wall of the drum body 14 through the brush 15.

[0030] In the present utility model, combined with Figure 1-6 As shown, a rotating shaft 8 rotatable on the drum shell 3 is also installed on the axis of the drum body 14 of this embodiment, and a through hole 5 for the rotating shaft 8 to rotate is penetrated through the side plate 6, and one end of the rotating shaft 8 rotates through the through hole 5.

When the drum body 14 is rotated, the rotating shaft 8 and the through hole 5 drive the drum body 14 to rotate axially in the drum shell 3.

[0032] Further, in order to facilitate the detachable installation of the drum body 14 on the drum shell 3, refer to Figure 1-2 As shown, the rotating shaft 8 is also provided with a pin 7 restricted on the side plate 6, and a pin hole 9 is provided on the outer wall of the end of the rotating shaft 8. The pin hole 9 is arranged on the outer side of the side plate 6, and at least part of one end of the pin 7 extends into the pin 7. The pin 7 is taken out of the pin hole 9, and the drum shell 3 can be pulled outward from the rotating shaft 8, so that the drum body 14 can be taken outward from the drum shell 3, so that the drum body 14 and the drum shell 3 can be easily inspected and repaired.

[0033] Further, in order to facilitate the rotational drive of the drum body 14, refer to Figure 1-2 As shown, a handle 1 for rotational driving is also installed on the side of the drum body 14 away from the side plate 6, and a turntable 2 is provided at one end of the drum body 14, and the handle 1 is eccentrically arranged on the side of the turntable 2 away from the drum body 14. The turntable 2 facilitates the eccentric installation of the handle 1 on the end of the drum body 14. At this time, one hand fixes the drum shell 3, and the other hand holds the handle 1, and the handle 1 is rotated clockwise for 3-5 circles to drive the drum body 3 to rotate. The drum shell 3 is fixed, so that the brush 15 of the drum shell 3 can fully straighten the cotton fiber. Finally, the side of the drum body with the scale line 16 is stopped at the detection port 4 opened in the drum shell 3, and the length of the cotton fiber is measured by reading the reading of the scale line 16 for assessment and research.
