Detailed Description

The technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 4, a cotton harvester cotton removing wheel comprises a wheel body 10 and a spacer 20, wherein the spacer 20 is arranged at one side of the middle of the wheel body 10 and is concentric with the wheel body; the other side of the middle of the wheel body 10 is provided with a matching structure 30 matched with the spacing sleeve 20. Through set up spacer sleeve 20 and cooperation structure 30 in the middle of wheel body 10, can make and take off the cooperation contact between the cotton wheel, increase stability, and then conveniently take off the cotton wheel and separate cotton fiber and cotton seed effectively. The design can improve the cotton stripping efficiency and reduce the cotton fiber residue rate. The presence of the mating structure 30 can effectively reduce the direct friction between the wheel body 10 and the spacer sleeve 20, reduce the mechanical damage to the cotton removing wheels, and avoid abrasion caused by the existence of a mating gap or low stability of installation between the cotton removing wheels.

Through the design, the stability of the cotton harvester cotton removing wheel is improved, and meanwhile, the problem of insufficient precision caused by independently installing the spacing sleeve 20 can be avoided because the wheel body 10 and the spacing sleeve 20 are more tightly matched. Therefore, the working efficiency and the reliability of the cotton removing wheel can be improved by the technical scheme.

In the above embodiments, the wheel body 10 and the spacer 20 are integrally formed, so in order to increase the demands and diversity of different customers, in some embodiments, the wheel body 10 and the spacer 20 may be formed independently, the spacer 20 is connected to the wheel body 10, and the two are bonded by glue; alternatively, the spacing mechanism of the spacing sleeve 20 may be omitted, and the separate wheel body 10 may be directly adopted, without using the spacing sleeve 20.

In the above embodiment, the fitting structure 30 is a fitting groove 31 having a circular shape. The interior of the engagement groove 31 engages the outer contour of the spacer sleeve 20. The circular fitting groove 31 has a rounded curve shape, and friction and abrasion can be reduced. This helps to reduce mechanical damage to the spacer sleeve 20 and the wheel body 10 and increases their useful life. The method for realizing the technical scheme is that a matching structure 30 with a circular matching groove 31 is designed and processed on the other side of the middle of the wheel body 10. The mating grooves 31 are sized and shaped to match the spacer 20 and ensure concentricity with the spacer 20 of the wheel body 10. Thus, the matching structure 30 of the wheel body 10 can be matched with the spacer sleeve 20 on the other wheel body 10 to increase stability, improve cotton removing efficiency and reduce mechanical damage.

In this embodiment, the spacer 20 is a sleeve with a central through hole in communication with the mating slot 31 and sleeved on the cotton removing shaft 40. The spacer 20 sleeved on the cotton removing shaft 40 can increase the direct contact between the wheel body 10 and the cotton removing shaft 40, and further improve the stability of the wheel body 10 and the cotton removing shaft 40. This reduces friction and wear and reduces mechanical damage to the wheel body 10 and the doffer shaft 40. The method for realizing the technical scheme is that the spacer sleeve 20 is sleeved on the cotton removing shaft 40, and is tightly matched with the cotton removing shaft 40 through the design of the middle through hole. Because the spacer sleeve 20 sleeved on the cotton removing shaft 40 is concentric with the wheel body 10 and matched with the matching groove 31 on the other wheel body 10, a good matching effect is realized. Thus, the spacer 20 of the wheel body 10 can achieve technical effects by sleeving the spacer with the cotton removing shaft 40, thereby reducing mechanical damage and improving cotton removing efficiency.

In this embodiment, a plurality of cotton removing structures 50 are disposed on the same side of the wheel body 10 as the spacer 20 and distributed circumferentially. This detail points out an additional design element on the wheel body 10, namely the doffing structure 50. By adding the cotton removing structures 50 to the wheel body 10 in a circumferential distribution, the surface area contacting cotton can be increased. This increases the friction and separation effect of the doffer wheel from the cotton, thereby improving the doffing efficiency. The circumferential distribution of the doffing structure 50 provides for a more uniform application of force and stimulation to aid in more thoroughly separating cotton fibers from cotton seeds. Thus, the quality of cotton removal can be improved, and the residual rate of cotton fibers can be reduced.

In a further embodiment, the wheel body 10 is provided with a locking structure 60 which cooperates with the cotton removing structure 50. This detail points out the auxiliary design elements that perform the function of the doffing structure 50. By the design of the locking structure 60, the cotton removing structure 50 and the wheel body 10 can be firmly connected together, so that the cotton removing structure is prevented from loosening or falling off in operation. This increases the stability of the doffer structure 50, ensuring that it is continually and effectively rubbed and separated from the cotton. The presence of the locking structure 60 may reduce relative movement between the doffing structure 50 and the wheel body 10, reducing mechanical damage caused by friction and vibration. This helps to extend the useful life of the doffer structure 50 and wheel body 10, reducing the cost of maintenance and replacement of parts. By mating the locking structure 60 with the doffing structure 50 and properly reinforcing, it is ensured that the doffing structure 50 is securely fixed to the wheel body 10 to achieve a stable doffing effect. In this way, the presence of the locking structure 60 enables a technical effect to be achieved, improving the stability of the doffing structure 50 and reducing mechanical damage.

In this embodiment, the locking structure 60 includes a first locking groove 61 and a second locking groove 62 formed on the upper and lower sides of the wheel body 10, and a grid-type locking groove 63 formed on the wheel body 10 and corresponding to the positions of the first locking groove 61 and the second locking groove 62. By providing the first locking groove 61 and the second locking groove 62 on the wheel body 10, a plurality of locking points can be provided, and the connection stability with the cotton removing structure 50 can be increased. The design of the grid-type locking groove 63 further improves the reliability of the locking structure 60, and ensures that the locking structure 60 is fixed in position and not easy to loosen. The method for realizing the technical scheme is that the wheel body 10 is provided with a first locking groove 61 and a second locking groove 62 which are generally positioned on the upper side and the lower side. At the same time, a grid-type locking groove 63 is provided at a corresponding position to provide a more stable and firm connection. The locking structure 60 may be secured in place on the wheel body 10 by mating the doffing structure 50 with a locking slot. The specific design of the grid-type locking groove 63 may be adjusted according to the actual requirements to ensure the connection firmness with the locking structure 60. By such arrangement, the locking structure 60 can effectively fix the cotton removing structure 50, improving the reliability and safety of connection.

In a further embodiment, the cotton removing structure 50 includes a cotton removing protrusion 51 and a cotton removing plate 52 which are respectively engaged with the first locking groove 61 and the second locking groove 62, and a cotton removing post 53 which is connected between the cotton removing protrusion 51 and the cotton removing plate 52 and is engaged with the grid type locking groove 63. By the fitting fit of the cotton removing protrusions 51 and the anti-falling plates 52 with the first locking grooves 61 and the second locking grooves 62, the cotton removing structure 50 is firmly connected to the wheel body 10, and the stability thereof is improved. At the same time, the cooperation of the anti-falling post 53 and the grid-type locking groove 63 increases the reliability of connection, preventing the cotton-falling structure 50 from loosening or falling off during operation. The design of the cotton stripping protrusions 51 and the anti-stripping plates 52 can increase the surface area contacted with cotton and improve the cotton stripping effect. The presence of the anti-drop post 53 can relieve the pressure between the cotton drop structure 50 and the cotton, reducing damage due to excessive pressure. The method for realizing the technical scheme is that the cotton removing convex blocks 51 and the anti-falling plates 52 are designed to be embedded and matched with the first locking grooves 61 and the second locking grooves 62. The cotton-removing protrusions 51 and the anti-removing plates 52 are attached to the first and second locking grooves, so that stable connection is ensured. Meanwhile, the anti-falling post 53 connected between the cotton falling bump 51 and the anti-falling plate 52 is engaged with the grid type locking groove 63, thereby increasing the reliability of connection. Thus, the design of the doffing structure 50 can achieve stable connection, improve the doffing effect, and reduce damage caused by excessive pressure.

In the above embodiment, the form of the cotton removing protrusions 51 may be designed according to specific requirements, for example, a stick, a needle or other shaped structures may be used. The cotton removing protrusions 51 should be uniformly distributed on the wheel body 10 and adapted to the motion track of the cotton removing wheel so as to achieve effective separation and cotton removing effects on cotton. Thus, the presence of the cotton stripping structure 50 can achieve the technical effect of improving the cotton stripping efficiency and the cotton stripping quality. The particular form of the locking structure 60 may vary depending on design requirements, and may be, for example, a lock nut, a locking ring, or other type of mechanical connection.

In some embodiments, the wheel body 10 and the spacer 20 are made of engineering plastic. The specific wheel body 10 and the spacer sleeve 20 are integrally formed cotton-removing wheel base structures after injection molding of mixed materials of glass fiber and nylon through injection molding equipment. The glass fiber and nylon materials have the advantage of light weight compared with the metal materials in the prior art; the working procedures of the processing technology are few, and the efficiency is high; the materials of the glass fiber and nylon are further lower than the product cost of the metal material, so that the cost is saved. The cotton removing structure 50 is an engineering plastic soft rubber structure. Specifically, the cotton removing structure 50 of the cotton removing wheel base structure is integrally formed after the PPU polyurethane soft rubber is injected by injection molding equipment. Not only the working procedures of the processing technology are reduced, but also the locking structure 60 on the base structure of the cotton removing wheel has extremely strong anti-falling performance, good stability and high safety.

In the above embodiment, the wheel body 10 and the spacer 20 are made of engineering plastic with a certain elastic function. The wheel body 10 and the spacer sleeve 20 are integrally formed into a cotton removing wheel base structure by injection molding, and in the installation process, twenty cotton removing wheel base structures are generally formed into a group. And two adjacent cotton removing wheel base structures are in close contact with each other and extrusion force exists between the two, so that the spacer sleeve 20 on the cotton removing wheel base structures is stressed to increase the compactness of being attached to the matching groove 31. The spacer 20 in the cotton removing wheel base structure can expand to a certain extent due to the occurrence of compression in the process of contact extrusion with the wheel body 10 on the other cotton removing wheel base structure, the port of the spacer 20 is tightly matched with the inner side wall of the matching groove 31, the stability of the adjacent cotton removing wheel base structure is further improved, and the stabilizing effect on a group of cotton removing wheel base structures is achieved.
