Description

Technical Field

[0001] The present invention relates to a distribution component for distributing seed cotton in a machine width direction, and also relates to a distribution assembly equipped with the distribution component. Background Art

[0002] Regarding seed cotton distribution, see Chinese patent CN108103588A, which describes an improvement to a seed cotton dispenser developed by Shandong Swan Cotton Machinery Co., Ltd. The background technology section provides a relatively detailed description of the structure and principles of seed cotton distribution. With technological advancements, cotton processing machinery and equipment are moving towards larger, more automated, and more intensive processes. The processing capacity of individual machines is increasing, and the machine width (for example, the width of the seed cotton processing section of a seed cotton cleaning machine) is growing, from approximately 2 meters to approximately 4 meters. Further increases in the future are possible.

[0003] As is known, seed cotton transportation relies primarily on wind power, which is well-suited for pipeline transportation. Most pipelines are circular (commonly known as round tubes). Due to wind system constraints, the diameter of the tubes cannot be increased indefinitely. For example, when a 400mm diameter round tube enters the long cotton inlet of a seed cotton cleaning machine with a 4m width, how to evenly distribute the material across the entire width of the machine, ensuring that the material is cleaned and distributed as evenly as possible, is a pressing issue.

[0004] As the original seed cotton distribution component, the triangular box served as the primary seed cotton distribution device in cotton processing, feeding seed cotton into, for example, the seed cotton cleaning machine, before the emergence of other seed cotton distribution components. Due to the small scale of traditional cotton processing plants, the processing capacity of individual machines was small, and the machine width was narrow, approximately 2 meters. As the seed cotton entered the elongated opening from the circular pipe, the triangular box in front of the elongated opening was used to evenly distribute the seed cotton. However, with technological advancements, the machine width of cotton processing equipment can now reach 4 meters, and will even increase in the near future. Simply relying on the triangular box for diffusion is no longer enough to evenly distribute the seed cotton within the machine width.

[0005] In light of this, Chinese patent document CN108103588A proposes a seed cotton distributor based on a modified triangular box. The main improvement is the installation of two adjustable baffles on the triangular box. Adjusting the angle of the baffles is equivalent to adjusting the angle of the triangular box according to the working conditions. However, this adjustment method cannot adapt to the current situation of further expansion of the machine width. The adjustable angle of the triangular box is limited to relatively controllable flow direction of the seed cotton, but it cannot extend the coverage of the seed cotton along the length of the elongated opening. Therefore, it still cannot adapt to the application of further expansion of the machine width. Summary of the Invention

[0006] The purpose of the present invention is to provide a distribution component that can adapt to the current situation of a larger machine width or further expansion and has better promotion and application prospects. The present invention also provides a distribution assembly equipped with the distribution component.

The controllable seed cotton flow is then divided into multiple seed cotton tributaries, thereby providing improved technical conditions for further lateral expansion of the seed cotton tributaries, thereby adapting to cotton processing equipment with relatively large machine widths. Furthermore, the distribution assembly laterally expands the seed cotton tributaries and finally connects the distribution pipes with the outlet pipes to collect the expanded seed cotton tributaries and deliver them to a given seed cotton processing machine, thereby adapting to larger machine widths overall.

[0040] C.Seed cotton. DETAILED DESCRIPTION

[0041] Since seed cotton C is generally transported by wind using pipelines, and the transport pipelines are generally round tubes, they have a certain axial direction. For example, when using a triangular box, the basic direction of the triangular box can be determined by the axial direction based on the round tube it is connected to.

[0042] It should be noted that, for example, for a pipeline for transporting seed cotton C, its axial direction is also the transport direction of the seed cotton C.

[0043] It should be noted that, for example, a triangular box generally has a rectangular cross-section, and the shell plates corresponding to the short sides are generally called side plates, while the shell plates corresponding to the long sides are generally called panels 27 and 32. The direction between the side plates is generally the transverse direction, while the direction between panels 27 and 32 is the thickness direction. The direction along the seed cotton flow can be expressed as the radial direction as described above, or as the longitudinal direction. Therefore, in the embodiments of the present invention, unless otherwise specified, the transverse, longitudinal, and thickness directions are all based on this.

[0044] Furthermore, it should be understood that when the horizontal direction is used as a reference, the horizontal direction is also generally referred to as the left-right direction.

[0045] Based on the longitudinal direction, that is, along the direction of seed cotton flow, there is a distinction between the front (stage) and the back (stage). The seed cotton distributor disclosed in Chinese patent document CN108103588A is the basis for the improvement of the present invention. In the embodiments of the present invention, part of the structure of the distribution pipe 7 and the distribution adjustment part 2 can be considered as a direct application or modification of the seed cotton distributor in Chinese patent document CN108103588A, especially the distribution pipe 7.

[0046] Figure 2 and Figure 6 The illustrated structure is an example of a distribution assembly, resembling the butted ends of two triangular boxes. The distribution assembly and its various segments are primarily connected using flanges, a common method of connecting pipes and will not be discussed further here. However, as a suitable pipe connection, this at least demonstrates that, for example, the outlet of the distribution regulating section 2 and the inlet of the wind force regulating section 3 should be identical in shape and size, and the shapes and sizes of the other segments should also be consistent.

[0047] Figure 1 The figure shows a three-dimensional structural diagram of the entire distribution assembly, which includes multiple segments, among which the flower inlet elbow 1 is used for flower inlet guidance.

[0048] As a relatively common configuration in the cotton field, seed cotton C usually needs to be dried before being sent to cotton processing equipment to control the moisture content of seed cotton C, which is beneficial to the subsequent processes such as opening and removing impurities of seed cotton.

[0049] After the seed cotton C is sent out from, for example, a dryer, it is usually based on wind power, usually suction. For example, a dust cage is provided at the front stage of the seed cotton cleaning machine, and the dust cage is connected to, for example, a fan, which generates negative pressure in the distributor by inducing air, so that the seed cotton enters the seed cotton distribution assembly from, for example, the cotton inlet bend 1.

[0050] Generally, the direction of the seed cotton flow of the seed cotton C discharged from the dryer is horizontal, but the distribution assembly is configured as a vertical direction in the embodiment of the present invention, showing the following: Figure 1 The status shown, for example Figure 1 The straight pipe 5 shown in FIG is in a substantially vertical state, and the seed cotton distribution assembly as a whole has the function of lifting the seed cotton flow upward.

[0051] The cotton inlet elbow 1 is used to guide the horizontal seed cotton flow into a substantially vertical state. The direction in which the seed cotton flow is finally guided out is generally not less than 60 degrees from the vertical direction.

[0052] For example, the seed cotton cleaning machine may be configured very high in the cotton processing production line. Figure 1The structure shown does not increase the height of the plant. In particular, most cotton processing plants process cotton from seed cotton to lint cotton, and the overall height of the production line is relatively high. The seed cotton cleaning machine is often the front-end equipment of the cotton processing equipment, and its position in the plant itself is often relatively high.

[0053] Figure 1 The inlet of the flower inlet elbow 1 is a rectangular opening, and the outlet is also a rectangular opening. Correspondingly, the flower inlet elbow 1 is a rectangular tube as a whole, which is suitable for connecting to a triangular box, for example.

[0054] Figure 1 The cotton inlet elbow 1 is a roughly 90-degree elbow, which is used to guide the horizontal seed cotton flow into a roughly vertical state and send it into, for example, the distribution and adjustment part 2.

[0055] It should be noted that some seed cotton cleaning machines may be relatively low, so for example, the distribution assembly may be arranged in a horizontal position. The cotton inlet elbow 1 may be omitted or replaced with a straight pipe portion only for transfer.

[0056] In order to show the state of seed cotton flow, for example, the distribution regulating part 2 is shown as the primary regulating part, and Figure 1 The wind force regulating section 3 shown in FIG is denoted as the secondary regulating section. The seed cotton flow undergoes primary and secondary conditioning, combing it into roughly two tributaries, which are then fed into two outlet bends 4. These tributaries are then connected to a distribution pipe 7 via a transfer pipe including the outlet bends 4. The distribution pipe 7 is a typical application of the seed cotton distributor disclosed in Chinese patent document CN108103588A and is a direct application of the seed cotton distributor. The specific structure of the distribution pipe 7 is applicable to the seed cotton distributor disclosed in Chinese patent document CN108103588A and will not be further described here.

[0057] The primary regulation part, such as Figure 5 The exemplary distribution adjustment unit 2 is located at Figure 1 The first stage of the middle distribution assembly is suitable for rectangular tube structures such as the flower inlet elbow 1. Figure 5 The inlet of the middle distribution and adjustment part 2 is a rectangular opening, and the outlet is also a rectangular opening, and the overall structure is also a triangular box. The small end of the traditional triangular box is generally connected to a round pipe, or the small end of the triangular box is generally a round opening, which is different from the Figure 1 The lower structure of the middle distribution pipe 7 is similar; Figure 5 The distribution and adjustment portion 2 shown in the example is an isosceles trapezoidal box. Generally speaking, its cross-section is a first rectangle with an aspect ratio of not less than 2. The opening at the end where the flange 26 is located is a rectangular opening with a relatively long long side and a short side approximately half the long side. Since the flange 21 is a relatively long rectangular opening, the aspect ratio is even greater.

[0058] Figure 5In the illustrated structure, with the first rectangle as a reference, the long sides of the first rectangle gradually shorten in the longitudinal direction of the primary regulating section, or in the direction of the seed cotton flow. This gradually narrowing channel accelerates the seed cotton flow and guides the cotton into a relatively regular stream, keeping the relatively dispersed seed cotton flow in a relatively controllable state. This structure increases the wind speed used to transport the seed cotton upwards, facilitating its rapid passage and preventing pipe blockage due to low wind speeds.

[0059] In some embodiments, air supply ports 28 are provided on both sides of the primary regulating portion to introduce external wind to change the trajectory of the seed cotton and achieve uniform distribution.

[0060] Since the seed cotton flow conveyed from, for example, the cotton inlet elbow 1 or other components may deviate to one side, for example, to a side plate of the primary regulating part, a first regulating baffle is provided in the primary regulating part. By changing the angle between the first regulating baffle and the longitudinal direction of the primary regulating part, the seed cotton flow direction is adjusted.

[0061] The first adjustment baffle is as follows Figure 5 The adjusting baffle 25 is described in detail in Chinese patent document CN108103588A. Figure 5 There is also a relatively clear representation in it. Figure 5 In the embodiment, the lower end of the adjustment baffle 25 is mounted on the panel 27 via the pin 22. Figure 5 The lower end is the feed end of the primary adjustment part. The rotating shaft 22 is located outside the primary adjustment part and is connected to the adjustment baffle 25 through the arm 23 and the intervention hole, so that the adjustment baffle 25 has the freedom of swinging. The intervention hole 24 is an arc-shaped hole, which can limit the rotation angle of the adjustment baffle 25.

[0062] In a preferred embodiment, the rotation angle range of the adjustment baffle 25 is controlled within 45 degrees.

[0063] Regarding the driving or adjustment of the adjustment baffle 25, there is a detailed description in Chinese patent document CN108103588A, which will not be repeated here.

[0064] Figure 1 In the figure, the second level of adjustment is completed by the wind force regulating unit 3. The second level is the secondary level, and the wind force regulating unit 3 is referred to as the secondary regulating unit.

[0065] As mentioned above, the secondary regulating part is connected to the outlet end of the primary regulating part based on the end-to-end flange connection, and the cross-section of the main body of the secondary regulating part is a second rectangle with an aspect ratio of not less than 2. The long side of the second rectangle gradually becomes longer from the inlet end to the outlet end of the secondary regulating part. In other words, the inlet size of the secondary regulating part is small and the outlet size is large, and the inner cavity forms a structure that is small at the top and large at the bottom, or the cross-sectional area of ​​the secondary regulating part gradually increases in the direction of the flower.

[0066] In addition to the aforementioned functions, the secondary regulating part is also used to divert the seed cotton flow, thereby providing technical conditions for the subsequent stage to further widen the seed cotton flow under the condition of diversion. Figure 1 and Figure 4 The end of the wind regulating part 3 in the figure, that is, the upper end shown in the figure, is provided with a top plate 36, which is used to seal the outlet end of the wind regulating part 3 to construct a seed cotton flow diversion channel. Figure 4 As can be seen in the figure, two flower outlets are opened on the top plate 36 to install, for example, a material cone 34 to connect the flower outlet elbow 4 of the round tube type.

[0067] like Figure 4 The material cone 34 shown in the figure is used to collect the wide incoming material into a state suitable for round tube transportation. Correspondingly, the adapter tube is adapted to connect the distribution component with the lower level components. Figure 1 There are three segments in the embodiment, and in some implementations there may be only one segment. The purpose of providing multiple segments is to adjust the flow situation of the seed cotton flow.

[0068] Figure 4 There are two material cones 34 in the machine, which are adapted to two flower outlet interfaces. If the machine width is further expanded, the flower outlet interfaces can be increased. When there are relatively more flower outlet interfaces, the burden of the adapted distribution pipe 7 is relatively small. For example, for a machine width of 2 meters, the traditional triangular box can basically meet the requirements. When the seed cotton distributor disclosed in the Chinese patent document CN108103588A is adopted, a better seed cotton distribution effect can be achieved. If, for example, the machine width is 3 meters, two flower outlet structures are adapted to two material cones 34, and then to two distribution pipes 7, each distribution pipe 7 only needs to adapt to a machine width of 1.5 meters, so that the burden is relatively small, and the seed cotton distribution effect is relatively easy to achieve.

[0069] Figure 1 The distribution pipe 7 shown in the figure is preferably the seed cotton distributor disclosed in the Chinese patent document CN108103588A, and may also be a traditional triangular box, especially when the number of cotton outlet interfaces is relatively large.

[0070] Regarding the number of flower outlets, it should not be more than 4. When there are relatively many flower outlets, for example Figure 4 The design of the top plate 36 shown in FIG would be very difficult.

[0071] In order to facilitate piping, the sealing plate is a folded plate, and the folds divide the sealing plate into sealing plate units. The number of sealing plate units corresponds to the flower outlet interfaces one by one.

[0072] exist Figure 4 In the structure shown, the closing plate unit is a flat plate, and the closing plate forms an arched structure with a high middle and low ends based on the folds.

[0073] Correspondingly, the arched direction of the arched structure is the longitudinal end of the secondary regulating portion, which is beneficial to combing the flow direction of the seed cotton flow.

[0074] Figure 2 In the illustrated structure, the adapter tube includes a flower-discharging elbow 4 to adjust the flower-discharging direction. Accordingly, the centripetal side of the flower-discharging elbow 4 is the transverse inward side of the secondary adjustment portion.

[0075] As a basic reference system, the secondary adjustment part shell plate corresponding to the short side of the second rectangle is marked as a side plate, and a first air supply port with adjustable opening is opened on the side plate.

[0076] In an embodiment of the present invention, multiple components contain air supply ports, such as Figure 4 The side plate of the wind force regulating part 3 is provided with an air supply port 37. Figure 5 The distribution and adjustment part 2 is provided with an air supply port 28 in the past, and for the distribution pipe 7, with reference to the seed cotton distributor disclosed in the Chinese patent document CN108103588A, the provision of an air supply port is also a preferred option.

[0077] In some embodiments, the first air supply port and other air supply ports may adopt the following structures:

[0078] Slots 38 are provided on opposite sides of the first air supply port;

[0079] A plug-in board 39 is provided to be inserted into the slot 38 , and the opening of the first air supply port is adjusted based on the extent to which the plug-in board 39 covers the first air supply port.

[0080] Similarly, the distribution pipe 7 is equipped with a second regulating baffle, and the flow direction of the seed cotton is adjusted by changing the angle between the second regulating baffle and the longitudinal direction of the distribution pipe;

[0081] A second air supply port with adjustable opening is provided on the distribution pipe shell plate corresponding to the short side of the third rectangle.

[0082] The matching structure of the insert plate 39 and the slot 38 is relatively simple in structure as a whole and is relatively easy to implement. Moreover, for the seed cotton distribution assembly, the sealing requirement is not high. The matching use of the insert plate 39 and the slot 38 can fully meet the requirements of seed cotton distribution.

[0083] As symmetrically arranged components, the first regulating baffle is provided at each of the two lateral ends of the primary regulating portion. Similarly, for other components that need to be configured with air supply ports, they can all be arranged in a bilaterally symmetrical manner.

[0084] The distribution assembly includes the aforementioned distribution components and also includes the dispersion and collection parts; specifically, the distribution assembly also includes:

[0085] The distribution pipe 7 corresponds to the transfer pipe one-to-one, and the cross section of the distribution pipe is a third rectangle, and in the discharge direction, the aspect ratio of the third rectangle gradually increases. As mentioned above, the distribution pipe 7 can directly use the seed cotton distribution pipe disclosed in Chinese patent document CN108103588A.

[0086] The distribution assembly further includes a discharge pipe 8, which is a component that connects the distribution assembly to the downstream cotton processing equipment. The feed end of the discharge pipe 8 is sequentially connected to the discharge end of the distribution pipe; accordingly, the cross-section of the discharge pipe 8 is a fourth rectangle with an aspect ratio of not less than 8, thereby having better lateral distribution capabilities.

[0087] The transfer pipe includes at least a flower outlet elbow 4 and a connecting elbow 6 located on the side of the distribution pipe 7, so as to guide the seed cotton to discharge along the panel corresponding to the third rectangular long side. The elbow is mainly used to change the direction of the seed cotton flow, but it also occupies a large space and the path of the seed cotton flow will also become longer. Under the condition of changing the direction, the length of the entire transfer pipe should be shortened as much as possible. Therefore, Figure 1 The structure shown further includes a straight pipe 5, which is used to connect the flower outlet elbow 4 and the connecting elbow 6.
