Description

Technical Field

[0001] This application relates to the field of agricultural implements technology, and in particular to a device for picking up and cleaning cotton that has fallen to the ground. Background Technology

[0002] Currently, cotton is generally harvested using mechanized methods, but it is impossible to achieve a 100% harvesting rate. Cotton cannot be completely harvested, and some cotton will fall into the cotton field, resulting in waste.

[0003] Collecting fallen cotton requires picking it up from the ground. However, during the collection process, the cotton often contains impurities such as cotton husks and long stalks. Currently, fallen cotton can be collected using mechanized methods or by manual picking.

[0004] However, when collecting fallen cotton mechanically, impurities such as cotton husks and long stalks are not easily removed, resulting in an excessively high impurity content in the cotton and reducing its quality. When picking up fallen cotton manually, labor costs are high and efficiency is low, making it impossible to guarantee the interests of farmers. Summary of the Invention

Detailed Implementation

[0066] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0067] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0068] In cotton production, fallen cotton results in a significant waste of cotton. Current technologies allow for both mechanical and manual collection of fallen cotton. However, existing mechanical collection methods rely on simple wind cleaning, which fails to remove long stalks that easily entangle with the cotton, leading to a high impurity content in the collected cotton and affecting its quality. Manual collection is inefficient and costly, failing to meet the needs of farmers.

[0069] This embodiment provides a device for picking up and cleaning fallen cotton. It is equipped with a crushing and conveying mechanism 2 and a cleaning mechanism 4 in conjunction with the picking mechanism 1. The crushing and conveying mechanism 2 can crush the fallen cotton containing impurities that has been rolled and thrown, so that the long straws are crushed and the impurities are leaked out through the hollow 31 of the support part 3. At the same time, the cleaning mechanism 4 can clean the impurities again while blowing out the cotton, which greatly improves the cleaning efficiency and provides strong support for ensuring the quality of cotton.

[0070] Example

[0071] Reference Appendix Figure 1 The device for picking up and cleaning fallen cotton provided in this application includes a picking mechanism 1, a crushing and conveying mechanism 2, a supporting part 3, and a cleaning mechanism 4. The picking mechanism 1 is used to drive and connect with a vehicle (not shown in the figure) to pick up and throw up the fallen cotton containing impurities. The crushing and conveying mechanism 2 is located downstream of the picking mechanism 1 and crushes and conveys the cotton away from the picking mechanism 1 to receive the fallen cotton containing impurities and crush the impurities in the cotton. The supporting part 3 is located on the side of the crushing and conveying mechanism 2 facing the ground, and at least a portion of the supporting part is provided with a hollow 31 to allow impurities to pass through. The cleaning mechanism 4 is located downstream of the crushing and conveying mechanism 2 and extends in a direction away from the ground. The cleaning mechanism 4 is provided with a blowout 41 at the end away from the ground. The blowout 41 is used to movably connect to the cotton collection space to convey and blow out the cleaned fallen cotton in a direction away from the ground.

[0072] Specifically, in order to solve the problems of poor mechanized collection effect and high cost and low efficiency of manual collection in the collection of fallen cotton, which cannot meet the needs of fallen cotton collection, this application provides a fallen cotton picking and cleaning device. It is equipped with a crushing and conveying mechanism 2 and a cleaning mechanism 3 in conjunction with the picking mechanism 1. The crushing and conveying mechanism 2 crushes the long straw and cotton husks in the fallen cotton containing impurities and uses the hollow 31 of the support part 3 to remove impurities. It is efficient and convenient and does not require secondary separation or treatment of impurities. Furthermore, the cleaning mechanism 4 can perform secondary cleaning while blowing out the fallen cotton, which greatly improves the cleaning effect.

[0073] The picking mechanism 1 may include, but is not limited to, a picking roller 11. The picking roller 11 may be equipped with rigid or flexible hooks. Driven by a vehicle (not shown in the figure), the picking roller 11 rotates, utilizing the centrifugal force generated by the rotation of the hooks to throw the cotton containing impurities from the cotton field toward the crushing and conveying mechanism 2. For example: refer to the attached... Figure 1 and attached Figure 14The pickup roller 11 has several evenly distributed sweeping sections 13 along its axial direction. Each sweeping section 13 includes several sweeping blades 17 spaced apart along the axial direction of the pickup roller 11. The sweeping blades 17 are flexible belts. When the pickup roller 11 rotates, the sweeping sections 13 can be thrown up by centrifugal force, sweeping up the impurity-laden cotton in the cotton field. In this embodiment, the number of sweeping sections 13 can be designed and adjusted according to actual needs, for example, six. Too few sweeping sections 13 will result in a small amount of impurity-laden cotton being swept up, leading to low efficiency. Too many sweeping sections 13 may cause entanglement or blockage between the sweeping blades 17 and the pickup roller 11 and the conveyor belt 14. In this embodiment, to improve the combing effect during the pickup process, refer to the attached... Figure 14 A fixing plate 18 for the cotton bollard 17 is provided on the pickup roller 11. The fixing plate 18 is set perpendicular to the pickup roller 11 along the axial direction of the pickup roller 11 to provide a contact surface for the cotton bollard 17. The fixing plate 18 has teeth perpendicular to the fixing plate 18 and opposite to the cotton bollard 17 at one end away from the pickup roller 11. Several teeth are distributed at intervals along the axial direction of the pickup roller 11. In imitation of human hands, the unharvested cotton bolls on the branches are combed and separated to achieve secondary harvesting.

[0074] It is understandable that the drive direction of the pickup roller 11 is opposite to the vehicle's travel direction to prevent impurities-laden cotton from falling onto the vehicle floor. (Refer to the attached document.) Figure 1 In this embodiment, the pickup roller 11 rotates clockwise. Therefore, the rotational speed of the pickup roller 11 is the same as the vehicle's input rotational speed. Furthermore, to improve the continuity between the pickup mechanism 1 and the crushing and conveying mechanism 2, a conveyor belt 14 is also provided (see attached diagram). Figure 1 and attached Figure 15The conveyor belt 14 is located downstream of the pickup roller 11. The conveyor belt 14 and the pickup roller 11 have the same transmission direction. The conveyor belt 14 has several spaced protrusions 15 along its transmission direction. The protrusions 15 extend along the axial direction of the pickup roller 11. When the rolling and throwing part 13 rotates to face the transmission belt 14, the rolling and throwing part 13 and the transmission belt 14 overlap at least partially in the direction perpendicular to the ground. Thus, the impurity-laden cotton that is rolled and thrown can fall directly onto the transmission belt 14 and be transmitted downstream. The conveyor belt 14 can achieve transmission through, but is not limited to, the cooperation of the transmission shaft and the transmission chain. The protrusions 15 on the conveyor belt 14 allow the impurity-laden cotton to roll on the conveyor belt 14 and be blocked by the protrusions 15 before rolling again. This improves the uniformity of the spread of the impurity-laden cotton on the conveyor belt 14 and prevents a large amount of impurity-laden cotton from gathering together and entering the crushing and conveying mechanism 2, causing blockage or affecting the crushing effect. Furthermore, in order to ensure a smooth transition between the picking mechanism 1 and the crushing and conveying mechanism 2, a connecting plate 16 can also be provided in this embodiment. The connecting plate 16 is a rigid or flexible plate, which is set between the conveyor belt 14 and the crushing and conveying mechanism 2 through the frame 12 to form a connecting channel, so that the impurity-containing cotton that has been spread evenly will not be transmitted to the cotton field by the conveyor belt 14, but will reach the crushing and conveying mechanism 2 through the connecting plate 16, thereby improving the impurity removal efficiency of the cotton.

[0075] Further, see Appendix Figure 3 and attached Figure 16 To improve the spreading degree of impurity-laden cotton on the conveyor belt 14, a spreading auger 19 is provided in this embodiment. The spreading auger 19 is located on the side of the conveyor belt 14 away from the ground. The spreading auger 19 includes a first blade 191 and a second blade 192 with opposite rotation directions. This allows the first blade 191 and the second blade 192 to generate thrust on opposite sides of the auger axis when the spreading auger 19 rotates around its auger axis, thereby effectively improving the spreading effect of impurity-laden cotton. It can be understood that the axis of the spreading auger 19 is parallel to the axis of the pickup roller 11.

[0076] The crushing and conveying mechanism 2 is located downstream of the picking mechanism 1 to receive the cotton containing impurities that has been rolled up and thrown to the ground. The crushing and conveying mechanism 2 is a rigid component structure, which can consist of a crushing mechanism and a conveying mechanism, or multiple conveying rollers arranged sequentially. During the conveying process, the crushing and conveying mechanism 2 can crush long straw and cotton husks. Correspondingly, after being crushed, the long straw can directly fall into the cotton field through the hollow 31 of the supporting part 3, efficiently removing impurities without requiring additional impurity treatment steps, thus simplifying the process and improving efficiency. In this embodiment, the crushing and conveying mechanism 2 can be arranged parallel to the horizontal plane to smoothly connect with the picking mechanism 1; of course, refer to the attached... Figure 2In this embodiment, a frame 12 can be provided. The frame 12 is a rigid structure. The frame 12 can serve as the overall shell of the ground cotton picking and cleaning device and can also be used for assembly with a vehicle.

[0077] The supporting part 3 is a rigid structure, which can be, but is not limited to, a plate-shaped structure, a trough-shaped structure, etc., as long as it can be set at the bottom of the crushing and conveying mechanism 2 to provide support. In this embodiment, the shape of the supporting part 3 is adapted to the crushing and conveying mechanism 2, and the hollow part 31 on the supporting part 3 can be designed and adjusted as needed, and can be in the form of a mesh or a grid.

[0078] The cleaning mechanism 4 is a rigid component structure, which may include, but is not limited to, a channel structure, and may include, but is not limited to, a fan or windmill structure to achieve the air outlet effect. The cleaning mechanism 4 is arranged in a direction away from the ground. Based on the characteristics of cotton being lightweight and easily blown up, the cleaning mechanism 4 can be arranged perpendicular to the ground or at an angle. In this embodiment, it is preferably set at an angle to reduce the difficulty of vertical blowing while ensuring that the cotton can be blown up; for example, an angle of 60-70 degrees with the horizontal plane. (See attached diagram) Figure 1 and attached Figure 2 In this embodiment, the cleaning mechanism 4 can be tilted towards the picking mechanism 1 to reduce the overall volume of the fallen cotton picking and cleaning device. The blowing outlet 41 can be rigid or flexible, and it can guide the blowing of fallen cotton. The blowing direction can be designed and adjusted according to actual needs. Depending on the form of different cotton collection spaces, the connection method between the blowing outlet 41 and the cotton collection space can be selected, for example: refer to the attached... Figure 4 The cotton collection space can be a cotton collection box 5, which is movably mounted on the vehicle or frame 12. The blow outlet 41 can be aligned with the opening of the cotton collection box 5. Alternatively, a transition connection channel (not shown in the figure) can be provided. For example, the cotton collection space can also be a bag, and the blow outlet 41 can be kept in communication with it by adhesive bonding and binding.

[0079] Based on the above, the cotton picking and cleaning device provided in this application, by cooperating with the picking mechanism 1 and setting up a crushing and conveying mechanism 2 and a cleaning mechanism 4, enables the cotton containing impurities that is rolled up and thrown from the cotton field to be crushed and conveyed in the crushing and conveying mechanism 2. The long stalks that are very easy to entangle the cotton are crushed and the impurities are leaked into the cotton field through the support part 3, achieving efficient impurity removal. Finally, the separated cotton is blown out and collected by the cleaning mechanism 4. It can not only improve the collection efficiency of cotton falling to the ground, but also effectively reduce the impurity rate of cotton falling to the ground by crushing long stalks. It can effectively solve the problems of poor mechanized collection effect and high cost and low efficiency of manual collection in cotton falling to the ground, which cannot meet the needs of cotton falling to the ground collection.

[0080] Further, see Appendix Figure 5 Appendix Figure 6Appendix Figure 7 and appendix Figure 8 In the specific implementation of the cotton picking and cleaning device provided in this embodiment, the crushing and conveying mechanism 2 includes at least one crushing group, which includes a first conveying roller 21 and a second conveying roller 22; the transmission direction of the first conveying roller 21 and the second conveying roller 22 is opposite to the transmission direction of the picking mechanism 1; the first conveying roller 21 and the second conveying roller 22 are respectively provided with a plurality of first crushing parts 23 and second crushing parts 24 protruding from the roller surface.

[0081] Specifically, in order to enable the crushing and conveying mechanism 2 to crush the long stalks of fallen cotton containing impurities, this embodiment sets at least one crushing group including a first conveying roller 21 and a second conveying roller 22. The number of crushing groups can be designed and adjusted according to actual needs, and can be, but is not limited to, set to... Figure 5 The three sets shown. The first conveyor roller 21 and the second conveyor roller 22 are respectively provided with a first crushing part 23 and a second crushing part 24 protruding from the roller surface. Both the first crushing part 23 and the second crushing part 24 are rigid structures and can be, but are not limited to, columnar, blocky, spiked, toothed, conical, etc. The first crushing part 23 and the second crushing part 24 can be the same or different. Furthermore, in this embodiment, the rotation direction of the first conveyor roller 21 and the second conveyor roller 22 is set to be opposite to the rotation direction of the pickup roller 11, that is... Figure 5 and Figure 6 The process proceeds counterclockwise, so that when impurity-laden fallen cotton enters the crushing and conveying mechanism 2, it can be pushed by the first crushing part 23 into the space between the first conveying roller 23 and the supporting part 3 for a first crushing. Then, when it is conveyed by the first conveying roller 23 to the second conveying roller 23, it is crushed a second time by the first crushing part 23 and the second crushing part 24. After reaching the second conveying roller 24, it is pushed by the second crushing part 24 into the space between the second conveying roller 24 and the supporting part 3 for a third crushing, effectively crushing long straw.

[0082] Furthermore, in order to achieve the pulverizing effect of the first pulverizing section 23 and the second pulverizing section 24, at least the following two configuration methods can be selected in this embodiment:

[0083] The first method, see attached document. Figure 7 and attached Figure 8The first crushing section 23 and the second crushing section 24 are different. The first crushing section 23 includes a plurality of crushing cones spaced apart along the axial direction of the first conveying roller 21, and the second crushing section 24 includes a plurality of crushing sharp teeth continuously arranged along the axial direction of the second conveying roller 22. The crushing cones can be, but are not limited to, cones or pyramids to ensure the compression and piercing of the impurity-laden cotton. The crushing sharp teeth are pointed plates, pyramids, or cones. In this embodiment, it is preferred that they are conical structures extending radially along the second conveying roller 22 and continuously arranged along the axial direction of the second conveying roller 22 to increase the density of the crushing sharp teeth. This ensures that the impurity-laden cotton on the first conveying roller 21 can be hooked onto the second conveying roller 22 and can also have a sharp crushing effect on impurities such as long straw. Furthermore, they are spaced apart in the axial direction to ensure that the effective area is large enough and to improve the crushing efficiency. Of course, in this embodiment, to ensure the crushing effect, several first crushing parts 23 are evenly distributed around the axial direction of the first conveyor roller 21; several second crushing parts 24 are evenly distributed around the axial direction of the second conveyor roller 22. The number of first crushing parts 23 and second crushing parts 24 can be designed and adjusted according to actual needs, but at least 12 around the roller axis. Furthermore, in this embodiment, when the first conveyor roller 21 and the second conveyor roller 22 are in motion, the first crushing parts 23 and the second crushing parts 24 are interlocked, so that when the first crushing parts 23 and the second crushing parts 24 rotate to a parallel horizontal plane, they partially overlap in the direction perpendicular to the ground, thus neither affecting the rotation of the other nor hindering the crushing of the impurity-laden cotton.

[0084] The second type: The first crushing part 23 and the second crushing part 24 are the same, and can both be crushing cones or crushing sharp teeth. In this embodiment, it is preferred that the first crushing part 23 and the second crushing part 24 are both configured to include crushing sharp teeth continuously arranged along the axial direction of the roller where they are located, so as to increase the crushing effect. The distribution of the first crushing part 23 and the second crushing part 24 is the same as described in the first type, and will not be repeated here.

[0085] Next, in this embodiment, the diameters of the first conveyor roller 21 and the second conveyor roller 22 in the multiple crushing groups can be designed and adjusted according to actual needs. The diameters of the conveyor rollers in the crushing conveying mechanism 2 can be set to be all the same, or they can be set to decrease sequentially in the direction away from the picking mechanism 1. As the distance conveyed by the crushing conveying mechanism 2 increases, the content of subsequent impurities decreases. Reducing the diameter of the relevant conveyor rollers will not affect the crushing effect and can also effectively reduce the weight of the overall device.

[0086] Further, see Appendix Figure 5 and attached Figure 9In the specific implementation of the cotton picking and cleaning device provided in this embodiment, the crushing and conveying mechanism 2 includes a third conveying roller 25; the third conveying roller 25 is disposed at one end of the crushing and conveying mechanism 2 facing the picking mechanism 1, and the transmission direction of the third conveying roller 25 is opposite to the transmission direction of the picking mechanism 1; the third conveying roller 25 is provided with a plurality of third crushing parts 26, and the plurality of third crushing parts 26 are spirally arranged around the axial direction of the third conveying roller 25.

[0087] Specifically, to ensure the pulverizing effect of the pulverizing and conveying mechanism 2, a third conveying roller 25 is provided in this embodiment. The third conveying roller 25 is equipped with a rigid, spirally distributed third pulverizing section 26. This allows the impurity-laden cotton thrown by the picking mechanism 1 to be spread along the axial direction of the third conveying roller 25 under the action of the third pulverizing section 26, improving the uniformity of the impurity-laden cotton on the third conveying roller 25. This effectively improves the pulverizing effect of the subsequent pulverizing group on the impurity-laden cotton and avoids local accumulation or missing parts on the third conveying roller 25 that would affect the subsequent pulverizing effect. The third pulverizing section 26 can be, but is not limited to, a cylinder, prism, cone, or pyramid. In this embodiment, it is preferably set in the form of a pyramid, ensuring not only effective spreading but also effective pulverization in conjunction with the first conveying roller 21.

[0088] Further, see Appendix Figure 5 and attached Figure 6 In this embodiment, the device for picking up and cleaning up loose cotton is provided. In a specific implementation, the supporting part 3 includes a first supporting part 32 and a second supporting part 33. The first supporting part 32 and the second supporting part 33 are arranged and connected sequentially along the transmission direction of the crushing and conveying mechanism 2. The first supporting part 32 corresponds to at least the third conveying roller 25. The first supporting part 32 has a complete supporting surface facing the third conveying roller 25. The second supporting part 33 has a plurality of grid-like perforations along the transmission direction of the crushing and conveying mechanism 2, and the size of the plurality of grid-like perforations gradually increases along the transmission direction of the crushing and conveying mechanism 2.

[0089] Specifically, in order to improve the impurity leakage effect of the support part 3, this embodiment sets the support part 3 as a first support part 32 without the perforation 31 and a second support part 33 with the perforation 31. The first support part 32 and the second support part 33 are both rigid structures, which can be, but are not limited to, plate-shaped, groove-shaped, etc. In this embodiment, the support part 33 is preferably set as an arc-shaped plate. The arc-shaped plate and the roller are concentric circles. The depth of the arc-shaped plate in the radial direction of the roller is 1 / 4-1 / 2 of the diameter of the roller. For example, at the two ends of the crushing and conveying mechanism 2 facing the picking mechanism 1 and the impurity removal mechanism 4, the support part 3 can be set to a larger depth. At the position corresponding to the middle of the crushing and conveying mechanism 2, the depth can be set to a smaller depth to ensure the transition connection between the corresponding rollers and avoid affecting the continuous transmission of the impurity-containing cotton. The first support part 32 can correspond to the third conveyor roller 25 alone, or it can correspond to both the third transmission roller 25 and the adjacent first conveyor roller 21 simultaneously. This allows the impurity-laden cotton thrown by the picking mechanism 1 to be fully conveyed and crushed, while also preventing long straws from getting stuck and blocked at the starting end of the crushing and conveying mechanism 2. The support surface is smooth and flat, allowing the impurity-laden cotton to be quickly pushed and conveyed within it. The second support part 33 is provided with a grid-like perforation, and the size gradually increases, corresponding to a gradual increase in the degree of crushing and a gradual improvement in the impurity leakage effect. Furthermore, since the final second conveyor roller 22 needs to cooperate with the starting end of the impurity removal mechanism 4, i.e., the fourth conveyor roller 42, in this embodiment, the second support part 33 is provided with a portion corresponding to the first fourth conveyor roller 42, allowing impurities during the impurity removal process to still leak out through the second support part 33. The grid-like perforation can be opened on the plate or formed by multiple rod-shaped or thin plate structures arranged at intervals. In the second configuration, reinforcing ribs can be provided at the bottom of the second support part 33 to ensure strength and connection.

[0090] Further, see Appendix Figure 10 The cotton picking and cleaning device provided in this embodiment includes, in a specific implementation, a cleaning mechanism 4 comprising at least two cleaning groups, which are arranged sequentially along a first direction a, the first direction a forming a specified angle with the horizontal plane; each cleaning group includes a fourth conveying roller 42 and a fifth conveying roller 43 arranged sequentially along the first direction a; the fourth conveying roller 42 is provided with a plurality of conveying plates 44 around its axial direction, so that the conveying plates 44 generate airflow along the first direction a when rotating with the fourth conveying roller 42, and the fourth conveying roller 42 is connected to the crushing and conveying mechanism 1; the fifth conveying roller 43 is provided with a plurality of fourth crushing parts 45, which are evenly distributed along the axial direction of the fifth conveying roller 43, and the fourth crushing parts 45 include serrations evenly distributed around the axial direction of the fifth conveying roller 43.

[0091] Specifically, in order to collect the fallen cotton after removing impurities such as long stalks, this embodiment sets up a cleaning mechanism 4, in which a fourth conveyor roller 42 and a fifth conveyor roller 43 are installed; see attached figure. Figure 11 A flexible conveyor plate 44 is provided on the fourth conveyor roller 42 so that when the fourth conveyor roller 44 rotates, the conveyor plate 44 can generate airflow to blow up the fallen cotton on it. In this embodiment, the conveyor plate 44 can be, but is not limited to, a belt, a glass sheet, etc. When the conveyor plate 44 rotates to be parallel to the ground, it partially overlaps with the second crushing part 24 of the second conveyor roller 22 in the direction perpendicular to the ground. This allows it to receive and remove the crushed and impurity-containing fallen cotton that has been transmitted from the crushing conveyor mechanism 2 to the impurity removal mechanism 4. The crushed and impurity-containing fallen cotton can be blown upward by the centrifugal swing of the conveyor plate 44. The conveyor plate 44 can be connected to the fourth conveyor roller 42 via a rigid connecting plate 46. The connecting plate 46 can be integrally formed with the fourth conveyor roller 42, or it can be welded, snap-fitted, etc. The connecting plate 46 is provided with screw holes for connecting the conveyor plate 44 and can be replaced, improving maintenance efficiency. The number of conveyor plates 44 can be designed and adjusted according to actual needs. In this embodiment, at least 12 conveyor plates are preferably provided. The radial dimension of the conveyor plate 44 along the fourth conveyor roller 42 can also be designed and adjusted according to actual needs. A larger dimension will generate a larger airflow. At the same time, in order to further ensure the impurity removal effect, a fifth conveyor roller 43 is provided in this embodiment. (Refer to the attached diagram.) Figure 12 The fifth transmission roller 43 is further crushed by the fourth crushing section 45. The fourth crushing section 45 has a rigid sawtooth structure and can extend radially around the axial direction of the fifth transmission roller 43 or extend tangentially along the outer surface of the fifth transmission roller 43. (See attached diagram.) Figure 13 In this embodiment, the second arrangement is preferred, where the saw teeth of the fourth crushing section 45 extend tangentially along the outer surface of the fifth conveyor roller 43 around its axial direction. This ensures that the saw teeth can effectively hook and penetrate impurities such as straw when rotating with the fifth conveyor roller 43. The density of the saw teeth can be designed and adjusted according to actual needs. The first direction a can be, but is not limited to, a direction toward the picking mechanism 1 and at an angle of 60-70 degrees to the horizontal plane.

[0092] Furthermore, in the specific implementation of the cotton picking and cleaning device provided in this embodiment, the transmission direction of the fourth conveyor roller 42 in the cleaning group of the crushing and conveying mechanism 2 is opposite to the transmission direction of the crushing and conveying mechanism 2; the transmission directions of the fourth conveyor roller 42 and the fifth conveyor roller 43 in the cleaning group are opposite.

[0093] Specifically, to ensure the cleaning effect, in this embodiment, the transmission direction of the fifth conveyor roller 43 is set to be opposite to that of the fourth conveyor roller 42, i.e., refer to the attached diagram. Figure 1The fourth conveyor roller 42 rotates clockwise, and the fifth conveyor roller 43 rotates counterclockwise, with the serrations on the fifth conveyor roller 43 facing the same direction as its rotation. The fourth conveyor roller 42 blows up the crushed cotton containing impurities that has fallen to the ground, and the fifth conveyor roller 43 effectively hooks and can crush the impurities again. At the same time, the crushed impurities can fall onto the second support part 33 in the opposite direction of the first direction a for impurity removal, thereby improving the impurity removal effect and efficiency.

[0094] Furthermore, in the specific implementation of the cotton picking and cleaning device provided in this embodiment, the cleaning mechanism 4 has a fourth conveying roller 42 at each end along the first direction a; the fourth conveying roller 42 is provided with a wind-gathering cover 47 on the side away from the picking mechanism 1; the diameter of the fourth conveying roller 42 in the cleaning mechanism 4 gradually increases along the first direction a; the size of the conveying plate 44 on the fourth conveying roller 42 away from the crushing and conveying mechanism 2 along the radial direction of the fourth conveying roller 42 is greater than the size of the conveying plate 44 on the fourth conveying roller 42 facing the crushing and conveying mechanism 2 along the radial direction of the fourth conveying roller 42.

[0095] Specifically, to ensure the effective blowing out of the fallen cotton after cleaning, this embodiment, in addition to setting at least two sets of cleaning groups to ensure that there is a fourth conveyor roller 42 at one end facing the crushing conveyor mechanism 2, also needs to set a fourth conveyor roller 42 at the end facing the blowout 41 to achieve the final blowing out of the fallen cotton; at the same time, in order to increase the airflow generated by the fourth conveyor roller 42 and ensure the blowing effect, this embodiment sets at least one air-gathering hood for each fourth conveyor roller 42 to ensure that the area where the fourth conveyor roller 42 is located is relatively sealed. The air-gathering hood 47 is a rigid plate structure, preferably an arc-shaped plate corresponding to the roller body. Of course, the air-gathering hood 47 can be set at the position corresponding to the fifth conveyor roller 43 according to actual needs. Setting the air-gathering hood 47 can effectively increase the airflow, and not setting the air-gathering hood 47 can allow impurities to leak through the gap and reduce the weight of the overall device. Furthermore, it can be understood that the aforementioned frame 12 has already covered the side of the cleaning mechanism 4 facing the picking mechanism 1, so the air-gathering hood 47 can be set on the side of the fourth conveyor roller 42 away from the picking mechanism 1. Meanwhile, to improve the blowing effect, in this embodiment, the size of the conveying plate 44 on each fourth conveying roller 42 can be increased along the first direction a to increase the amount of airflow generated. Therefore, it can be understood that in this embodiment, the diameter of each fourth conveying roller 42 can be the same or can gradually increase along the first direction a to increase the amount of airflow generated. In this configuration, the diameter of the fifth conveying roller 43 is the same.

[0096] It should be noted that in this embodiment, the rotation speed of the picking mechanism 1 is the rotation speed input by the vehicle, the rotation speed of the crushing and conveying mechanism 2 is relative to the rotation speed input by the vehicle, and the rotation speed of each crushing group increases sequentially. The rotation speed of the cleaning group in the cleaning mechanism 4 is at least 2000 r / min. It is understood that the vehicle must have a drive structure corresponding to each mechanism. This setting can be easily understood by those skilled in the art, and will not be elaborated on here.

[0097] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
