Description

Technical Field

[0001] This utility model relates to the field of seed cotton cleaning technology, specifically to a seed cotton cleaning device with a single-channel cleaning roller. Background Technology

[0002] During the harvesting, transportation, and initial processing of seed cotton, foreign fiber impurities such as mulch film, chemical fiber filaments, and yarn ends are often mixed in. These foreign fiber impurities seriously affect the quality of cotton and may cause problems such as yarn breakage and defects in subsequent spinning and weaving processes. Therefore, it is necessary to separate and remove foreign fibers from seed cotton during processing. Currently, various seed cotton foreign fiber cleaning devices have been proposed, but they still have problems such as complex structure or incomplete cleaning. For example, the existing CN201183854Y double-group winding roller type seed cotton three-fiber cleaning machine uses two sets of independent winding cleaning channels to work alternately to reduce cleaning downtime. The winding rollers still need to be manually cleaned at regular intervals, and the number of cleaning components and transmission components has increased exponentially, making the overall structure complex. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a seed cotton cleaning device with a single-channel cleaning roller to solve the problems of poor cleaning effect of foreign fibers in seed cotton and complex cleaning roller structure in the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a seed cotton cleaning device with a single-channel cleaning roller, characterized in that it includes: The machine casing has a cleaning chamber inside. At the top and bottom ends, there are feed inlets and cotton discharge channels connected to the cleaning chamber, respectively. A storage box connected to the bottom of the cleaning chamber is also provided on one side of the cotton discharge channel. The cleaning rollers are arranged in multiple sets at intervals along the height direction. Each set of cleaning rollers consists of a lever shaft and a rotating shaft fixedly connected to both ends of the lever shaft. The rotating shaft is connected to the inside of the machine housing in a counterclockwise rotation. The lever shaft and the rotating shaft are eccentrically distributed. Multiple sets of levers are evenly arranged at intervals along the circumferential direction, and the length of the multiple sets of levers decreases sequentially from the direction closest to the axis of the rotating shaft to the direction farthest from the axis of the rotating shaft. A drive assembly is used to drive multiple sets of cleaning rollers to rotate synchronously. The cleaning assembly includes multiple sets of brushes distributed one-to-one with the cleaning roller, the brushes being positioned above the cleaning roller on the side near the storage bin.

[0005] Furthermore, the outer ends of multiple levers located on the same cleaning roller rotate along the same circular path.

[0006] Furthermore, the outer ends of multiple levers located on the same cleaning roller rotate along multiple circular paths of different diameters.

[0007] Furthermore, an adjustment assembly is provided between the side wall of the housing and the brush. The adjustment assembly includes a sliding plate, a slider, and a spring. The slider is fixedly connected to the inner side of the sliding plate. A sliding groove is provided on the side wall of the housing to slide in cooperation with the slider. The length of the sliding groove is horizontally distributed along the radial direction of the brush. The two ends of the spring in the length direction are respectively connected to the side wall of the sliding groove and the slider. The two ends of the brush in the length direction are connected to the sliding plate.

[0008] Furthermore, a partition is provided below the cleaning roller to divide the lower part of the cleaning chamber into a waste storage box and a cotton discharge channel.

[0009] Furthermore, the multiple sets of cleaning rollers are distributed in a stepped manner in the direction from the storage box to the cotton discharge channel.

[0010] The technical solution provided by this utility model has the following advantages compared with the prior art: 1. Multiple sets of cleaning rollers arranged along the height direction are used to clean foreign fibers from seed cotton. A cleaning component is set on the side of the cleaning roller away from the seed cotton. The cleaning component can push the foreign fibers on the lever to the storage box below, thereby realizing real-time cleaning and removal of foreign fibers, reducing downtime and effectively improving work efficiency. 2. The cleaning roller adopts an eccentrically set rotating shaft and lever shaft. When the rotating shaft rotates, the outer circle of the lever shaft rotates along a circular path around the axis of the rotating shaft, causing the seed cotton to be tumbled in both the lateral and longitudinal directions, increasing the probability of contact between foreign fibers and the lever. Combined with the stepped setting of multiple sets of cleaning rollers, the flow path of the seed cotton can be effectively extended, further improving the capture probability of foreign fibers. 3. The rotation trajectories of the outer ends of the multiple sets of levers on the cleaning roller are on circular paths of different diameters. During the rotation of the cleaning roller, different length levers can capture foreign fibers at different depths in the seed cotton. 4. The spacing between the brush and the cleaning roller can be adaptively adjusted by the adjustment component to accommodate different lengths of the lever, so as to achieve effective contact between the lever and the brush while avoiding hard contact between the lever and the bristles, thereby reducing impact wear between the lever and the brush, extending the brush life, and avoiding the decrease in cleaning efficiency due to brush wear. 5. Compared with the existing dual-channel cleaning roller seed cotton cleaning machine, this device has a better cleaning effect, and the overall structure is simple, with a long replacement and maintenance cycle for parts and low cost.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0014] First Embodiment like Figures 1-3As shown, this utility model provides a seed cotton cleaning device with a single-channel cleaning roller, including a housing 1. A cleaning chamber 3 is provided inside the housing 1. A feed inlet 2 is provided at the top and communicates with the cleaning chamber 3 for seed cotton to enter the cleaning chamber 3. A partition 4 is fixedly connected to the middle of the bottom of the housing 1. The partition 4 divides the left and right sides of the bottom of the housing 1 into a storage box 6 and a cotton discharge channel 5. The cleaned seed cotton is output to the subsequent process or collected through the cotton discharge channel 5. The storage box 6 is used to collect the separated foreign fibers and other impurities. Multiple sets of cleaning rollers 7 are evenly arranged from top to bottom inside the cleaning chamber 3. A set of cleaning components is attached to the left side of each set of cleaning rollers 7. The foreign fibers on the cleaning rollers 7 can be cleaned by the cleaning components and fall into the storage box 6.

[0015] Specifically, the cleaning roller 7 consists of a rotating shaft 9, a fixed disk 10, a lever shaft 11, and levers 12. The lever shaft 11 is horizontally distributed along its length in the front-to-back direction. Both ends of the lever shaft 11 are fixedly connected to the rotating shaft 9 via the fixed disk 11. The rotating shaft 9 and the lever shaft 11 are eccentrically distributed, while the lever shaft 11 and the fixed disk 10 are coaxially distributed. In this embodiment, eight sets of levers 12 are provided, evenly distributed along the circumference of the lever shaft 11, i.e., adjacent sets of levers 12 are spaced 45° apart. Furthermore, the length of the levers 12 decreases sequentially from near the axis of the rotating shaft 9 to away from the axis of the rotating shaft 9. (Refer to...) Figure 1 or Figure 3 The uppermost set of cleaning rollers 7 is described below. In the illustrated state, the axis of the rotating shaft 9 of this set of cleaning rollers 7 is located horizontally to the right of the axis of the lever shaft 12. The rightmost set of levers 12 on the lever shaft 12 is the longest, and the leftmost set of levers 12 is the shortest. Furthermore, the lengths of the three sets of levers 12 above and the three sets of levers 12 below decrease sequentially from right to left, exhibiting a symmetrical distribution. In addition, it should be noted that in this embodiment, the rotation trajectories of the outer ends of the eight sets of levers 12 are located on the same circular path b. Through the eccentric setting of the lever shaft 11, the outer surface of the lever shaft 11 rotates counterclockwise along the circular path a. The resulting circular motion causes the seed cotton to undergo both lateral and longitudinal tumbling, increasing the probability of contact between foreign fibers and the levers 12, thereby improving the capture efficiency of foreign fibers by the levers 12.

[0016] The cleaning assembly includes four sets of brushes 8 spaced apart from top to bottom. The four sets of brushes 8 correspond one-to-one with the four sets of cleaning rollers 7 and are located on the radial left side of the cleaning rollers 7. The length of the brushes 8 is horizontally distributed along the front-to-back direction. The brushes 8 are fixed between the front and rear side walls of the housing 1 and are in contact with the lever 12. The lever 12 captures foreign fibers and rotates them to one side of the brushes 8, where they can be cleaned by the brushes 8 and fall into the storage box 6 below.

[0017] In this embodiment, four sets of cleaning rollers 7 are provided. The four sets of cleaning rollers 7 are arranged in a stepped manner from left to right from top to bottom. The lowest set of cleaning rollers 7 is located above the partition 4. During the falling process, the seed cotton passes through the cleaning rollers 7 at different horizontal positions. Through the stepped staggered arrangement of the cleaning rollers 7, the falling process of the seed cotton is divided into multiple stages and contacts the cleaning rollers 7 at different horizontal positions. This causes the cotton flow to move downward in a zigzag path in the cleaning chamber 3, effectively extending the flow path of the seed cotton, generating multiple tumbling and dispersion, and making it easier for foreign fibers to be captured by the lever 12.

[0018] The drive assembly includes a drive motor, synchronous pulleys, and a synchronous belt. The rotating shaft 9 is connected to the inner wall of the housing 1 through bearings in a counterclockwise rotation. One end of each rotating shaft 9 extends out of the housing 1 and is coaxially fixedly connected to a synchronous pulley. The output shaft of the drive motor is connected to multiple sets of synchronous pulleys through synchronous belt transmission, thereby driving multiple sets of rotating shafts 9 to rotate synchronously counterclockwise through the drive motor. The above structure is prior art and is therefore not shown in the attached drawings, and will not be described in detail.

[0019] Second Embodiment The overall structure of this embodiment is basically the same as that of the first embodiment, except that the length of the lever 12 on the cleaning roller 7 is set.

[0020] like Figure 4 As shown, both ends of the lever shaft 11 along its length are also fixedly connected to the rotating shaft 9 via a fixed plate 10. The lever shaft 11 and the rotating shaft 9 are eccentrically arranged. Multiple sets of levers 12 are provided on the lever shaft 11. The lengths of the multiple sets of levers 12 decrease sequentially in the direction from near the rotating shaft 9 to away from the rotating shaft 9, and the outer end paths of the multiple sets of levers 12 are located on multiple circular paths with different diameters.

[0021] Specifically, in this embodiment, the lever 12 is provided with eight sets, in Figure 4 In the view state, the two sets of levers 12 located on the right and left sides of the rotation axis 9 are the longest and shortest, respectively. The outer path trajectory of the longest lever 12 on the right is a circular path c, and the outer path trajectory of the shortest lever 12 on the left is a circular path g. The three sets of levers 12 at the top and the three sets of levers 12 at the bottom are symmetrically distributed, with the length decreasing from right to left. Taking the three sets of levers 12 at the top as an example, their outer circular path trajectories are d, e, and f, respectively.

[0022] To ensure that lever 12 contacts brush 8 to remove foreign fibers from lever 12, the shortest lever 12 should contact the bristles on brush 8 when rotated to the side of brush 8. Furthermore, to avoid interference between lever 12 and brush 8, the length of the longest set of levers 12 should be less than the minimum horizontal distance between lever shaft 11 and brush 8 shaft, and the free length of the bristles on brush 8 should be greater than the maximum length difference between levers 12 (i.e., the length difference between the longest and shortest levers).

[0023] In this embodiment, by setting levers 12 with different rotation trajectories, multi-layer turning and combing of seed cotton can be achieved, thereby further improving the efficiency of cleaning foreign fibers from seed cotton.

[0024] Third Embodiment Based on the second embodiment, this embodiment includes an adjustment component connected between the brush 8 and the side wall of the housing 1, which is used to adaptively adjust the horizontal distance between the brush 8 and the cleaning roller 7.

[0025] like Figure 5 As shown, the adjustment assembly includes a sliding plate 14, a slider 15, and a spring 16. The front and rear side walls of the housing 1 are provided with sliding grooves 13, which penetrate the thickness direction of the front or rear side wall of the housing 1 and are horizontally distributed along the left and right directions. The sliding plate 14 is located on the outside of the housing 1, and the slider 15 is fixedly connected to the inner side of the sliding plate 14 and slidably connected to the inside of the sliding groove 13. The front and rear ends of the brush 8 pass through the sliding groove 13 and are fixedly connected to the sliding plate 14.

[0026] In this embodiment, two sets of sliders 15 are arranged at intervals on the left and right. The two ends of the spring 16 in the length direction are connected to the left set of sliders 15 and the left side wall of the slide groove 13, respectively. In the natural state, the spring 16 is in a compressed state, which can drive the left set of sliders 15 together with the slide plate 14 to slide to the right and press against the right side wall of the slide groove 13. The right set of sliders 15 is located on the right side of the brush 8. This set of sliders 15 not only plays a sliding guide role, but also serves as a limiting component to prevent the shaft end of the brush 8 from colliding with the right side wall of the slide groove 13.

[0027] When the shortest lever 12 is located on the left and in contact with the brush 8, the brush 8 is in the position as follows: Figure 5 As shown, the brush 8 is located at the far right of the slide groove 13, and the spring 16 is in a compressed state. When the longest set of levers 12 rotates counterclockwise along the circular path c to the left side of the brush 8, the brush 8 will move to the left a certain distance due to the hardness of the bristle roots. At the same time, the spring 16 will be further compressed to avoid the levers 12 being too long and interfering with the bristle roots, which would damage the brush 8. After the longest set of levers 12 has rotated, the brush 8 will move to the right a certain distance under the reset action of the spring 16.

[0028] Since the bristles on the brush 8 have greater stiffness closer to the root, when the lever 12 contacts the bristles, the longer the lever 12 is, the greater the impact damage to the root of the bristles on the brush 8. This device reduces the impact wear between the lever 12 and the brush 8 by setting an adjustment component to adaptively adjust the distance between the brush 8 and the cleaning roller 7.

[0029] In addition, a sealing plate 17 is provided in this embodiment. The sealing plate 17 is disposed inside the housing 1 and is fixedly connected to the slider 15. It is provided with a through hole for the end of the brush 8 shaft to pass through. The lengths of the sealing plate 17 and the sliding plate 14 are both greater than the length of the slide groove 13. When the slider 15 is in the extreme position in the left and right directions, the sealing plate 17 and the sliding plate 14 can effectively seal the slide groove 13 to prevent internal seed cotton, foreign fibers or external impurities from entering and affecting the normal operation of the adjustment component.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
