Description

Technical Field

[0001] The present invention relates to the field of seed cotton cleaning equipment, and in particular, to a combined seed cotton cleaner. Background Art

[0002] The seed cotton cleaner is mainly used to remove impurities in cotton (such as cotton seeds, leaf debris, dust, etc.). It physically separates and screens the cotton through a variety of cleaning components to remove impurities. For seed cotton with a high impurity content, there are still some problems in the use of existing equipment. For example, the following solutions are disclosed in the prior art:

[0003] Chinese Patent (Publication No. CN117468099 A, Publication Date: November 6, 2023) discloses an inclined seed cotton cleaner and a studded roller, including: a cleaning box with a communication port at the lower side of the box body, a cotton inlet at the upper side of the lower end of the box body, and a cotton outlet at the upper end; a studded roller group is located inside the cleaning box and is arranged along the inclined direction of the cleaning box body; a transmission mechanism is used for the transmission between the studded rollers in the studded roller group to make the rotation directions of the studded rollers the same, and the direction of the linear velocity node parallel to the arrangement direction of the studded roller group on the upper side of the studded roller is obliquely upward; and an impurity box is located below the cleaning box to receive the cleaned sundries. Although this solution sets multiple obliquely arranged studded roller groups, it cannot effectively clean seed cotton with a high impurity content.

[0004] Chinese Patent (Publication No. CN110117819 A, Publication Date: August 13, 2019) discloses a modular seed cotton cleaner, including a machine shell box body, an arc-shaped grate plate divides the box body, one side has a seed cotton inlet channel, a first seed cotton outlet channel, a feeding roller, and a seed cotton cleaning drum, and the other side has a V-shaped baffle, and the bottom of the V-shaped baffle is connected to the outside of the box through a screw feeder; in order to clean seed cotton with a high impurity content, this solution needs to configure multiple modular structures, and the structure is relatively complex. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a combined seed cotton cleaner, which realizes the effective cleaning of seed cotton with a high impurity content through the integration of a primary cleaning bin and a secondary cleaning bin, and can shorten the travel between seed cotton processes and save installation space.

[0006] In order to achieve the above purpose, the present invention is realized through the following technical solutions:

[0007] An embodiment of the present invention provides a combined seed cotton cleaner, including a primary cleaning bin and a secondary cleaning bin, and the primary cleaning bin and the secondary cleaning bin are connected through a conveying channel;

[0008] A first impurity box is provided below the primary cleaning bin, and a second impurity box is provided below the secondary cleaning bin. The first impurity box and the second impurity box are separated by a waste discharge baffle; the outlets of the first impurity box and the second impurity box both correspond to above the waste discharge bin.

[0009] A plurality of first spike roller assemblies are installed side by side in the primary cleaning bin, and a grid bar assembly is provided below the first spike roller assemblies; a second spike roller assembly is installed in the secondary cleaning bin, and a semi-surrounding grid bar is provided outside the second spike roller assembly; a discharge channel is connected to the side of the secondary cleaning bin opposite to the semi-surrounding grid bar.

[0010] As a further implementation, the primary cleaning bin is arranged to be inclined upward.

[0011] As a further implementation, the inclination angle of the primary cleaning bin is 30° to 40°.

[0012] As a further implementation, the first spike roller assembly includes a first tube shaft, and a plurality of first spikes are uniformly distributed axially on the first tube shaft;

[0013] The second spike roller assembly includes a second tube shaft, and a plurality of second spikes are uniformly distributed axially on the second tube shaft;

[0014] Among them, the diameter of the second tube shaft is larger than the diameter of the first tube shaft.

[0015] As a further implementation, the length of the first spike is greater than the length of the second spike.

[0016] As a further implementation, the diameter of the second tube shaft is 2 to 4 times the diameter of the first tube shaft.

[0017] As a further implementation, the grid bar assembly is composed of a plurality of grid bar units connected together to form a wavy structure;

[0018] The grid bar units correspond to the first spike roller assemblies one by one.

[0019] As a further implementation, the wrapping range of the semi-surrounding grid bar is 180° to 215°.

[0020] As a further implementation, integral wall panels are installed on both sides of the primary cleaning bin, and spike roller supports are installed inside the integral wall panels so that each first spike roller assembly is on the same center line.

[0021] As a further implementation, a waste discharge auger is installed in the waste discharge bin.

[0022] The beneficial effects of the present invention are as follows:

[0023] (1) The present invention includes two cleaning bins that jointly complete the entire cleaning process; and the impurity bins of the two share a single impurity discharge baffle, which guides the impurities on both sides at the same time, and then is finally discharged outside the machine body through the shared impurity discharge auger; this can not only save installation space but also shorten the process of cottonseed cleaning and processing.

[0024] (2) In the primary cleaning bin of the present invention, multiple first spike roller assemblies are provided, and the cottonseed runs above the first spike roller assemblies. Instead of having the cottonseed in clusters or with a high impurity content running in the channel formed by the spike roller and the grid bar, this avoids damage to important components such as the spike roller and the grid bar; moreover, since the length of the first spikes is relatively long, the space formed between the grid bar and the root of the first spikes is relatively large, and the loosening effect of the cottonseed is better.

[0025] In the secondary cleaning bin, the cottonseed is cleaned between the second spike roller assembly and the semi - enclosed grid bar. The semi - enclosed grid bar can increase the cleaning area, and with large - diameter and short spikes, it is easier to form single - grain cottonseed, reducing damage to the cottonseed and the formation of locked filaments.

[0026] By adopting different cottonseed cleaning methods in the primary cleaning bin and the secondary cleaning bin, thorough cleaning of the cottonseed is achieved after two - stage treatment, improving the quality of cottonseed cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0036] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0037] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0038] Combined with Figure 1 As shown, this embodiment provides a combined cottonseed cleaning machine, which includes a primary cleaning bin 1 and a secondary cleaning bin 2. One end of the primary cleaning bin 1 is provided with a feeding port 21. A first spike roller assembly 10 is installed in the primary cleaning bin 1, and a second spike roller assembly 11 is installed in the secondary cleaning bin 2. The primary cleaning bin 1 and the secondary cleaning bin 2 are connected through a conveying channel 3. The cottonseed processed by the first spike roller assembly 10 in the primary cleaning bin 1 enters the secondary cleaning bin 2 through the conveying channel 3 and is further processed by the second spike roller assembly 11. Even for the fallen cotton with a high impurity content, the impurities can be cleaned after the above two treatments.

[0039] The processing methods of the cottonseed in the primary cleaning bin 1 and the secondary cleaning bin 2 are different, and are specifically realized through the following structure:

[0040] Combined with Figure 1 and Figure 2 As shown, a plurality of first spike roller assemblies 10 are installed in the primary cleaning bin 1. The centers of the first spike rollers 17 are located on the same straight line, and this straight line forms a certain angle with the horizontal direction, so that while the first spike rollers 17 cooperate to process the cottonseed, it can be transported upward. Therefore, the primary cleaning bin 1 is installed obliquely, and its output end is higher than the input end. In this embodiment, the inclination angle of the primary cleaning bin 1 is 30° to 40°, which can ensure the smooth transportation of the processed cottonseed and prevent the cottonseed from falling back to the input end.

[0041] The first thorn roller assembly 10 is arranged in sequence from the input end to the output end of the primary cleaning chamber 1. The number of first thorn roller assemblies 10 installed is determined according to the seed cotton processing requirements. For example, six first thorn roller assemblies 10 are installed. The two ends of the first thorn roller assembly 10 are respectively connected to the wallboard. The wallboard of this embodiment is an integrated wallboard 14. Figure 3 As shown, a thorn roller support 15 is fixed on the inner side of the integrated wall panel 14, and the thorn roller support 15 has a plurality of support grooves evenly distributed along the length direction; compared with the spliced ​​structure, the integrated wall panel 14 reduces the probability that the centers of the first thorn roller assemblies 10 are not on the same center line, so as to ensure the cleaning effect.

[0042] Combination Figure 4 As shown, the first thorn roller assembly 10 includes a first tube shaft 16 and a first thorn 17, and a plurality of first thorns 17 are evenly distributed around the circumference of the first tube shaft 16; in this embodiment, the first thorns 17 are distributed in the same longitudinal section of the first tube shaft 16, and the first thorns 17 form a cross-shaped distribution. For the first-level cleaning link, in order to ensure the cleaning effect, the usual short thorns are adjusted to long thorns, and the diameter of the first tube shaft 16 is reduced; wherein the length of the first thorn 17 is 80 to 120 mm. The smaller the diameter of the tube shaft, the longer the length of the first thorn 17, which can better hook and pull the seed cotton with more impurities, and has a certain loosening effect on the clumped seed cotton, avoiding equipment blockage and equipment damage caused by blockage.

[0043] A grating assembly 12 is installed at the lower side of the first spike roller assembly 10, and the lower side of the primary cleaning chamber 1 is connected to the first impurity box 6, and the grating assembly 12 is located at the entrance of the first impurity box 6. Figure 5 As shown, the lattice grille assembly 12 is a one-piece structure, that is, it is connected as a whole by a plurality of lattice grille units 20, and the lattice grille units 20 correspond to the first spike roller assembly 10 one by one. The surface of the lattice grille unit 20 corresponding to the first spike roller assembly 10 is an arc surface, so that the lattice grille assembly 12 forms a wavy structure as a whole. The one-piece lattice grille assembly 12 can enhance stability and improve self-operation efficiency.

[0044] The installation position of the second spike roller assembly 11 is lower than the output end of the first cleaning chamber 1. Figure 6As shown, the second spike roller assembly 11 includes a second tube shaft 18 and second spikes 19, with a plurality of second spikes 19 evenly distributed circumferentially around the second tube shaft 18; the size of the second spike roller assembly 11 is designed based on the size of the first spike roller assembly 10 to enable the two to cooperate to achieve two-stage separation. Specifically, the diameter of the second tube shaft 18 is larger than that of the first tube shaft 16, and the length of the second spike 19 is shorter than that of the first spike 17; in this embodiment, the diameter of the second tube shaft 18 is 2 to 4 times that of the first tube shaft 16, and the length of the second spike 19 is 50 to 80 mm. When the linear velocity remains unchanged, the rotation speed of the roller with a larger diameter is relatively lower, which is more likely to form single-lint cotton, reducing damage to the lint cotton and the formation of locked filaments.

[0045] At the same time, in order to increase the cleaning area, a semi-enclosed grid 13 is adopted in this embodiment. Combining Figure 6 and Figure 7 As shown, the semi-enclosed grid 13 is arranged outside the second spike roller assembly 11. One end of the semi-enclosed grid 13 is connected to the conveying channel 3, and the other end is connected to the discharge channel 4. The discharge channel 4 is arranged outside the second spike roller assembly 11 and is a vertically downward channel, facilitating the discharge of the lint cotton after impurity removal.

[0046] The coverage range of the semi-enclosed grid 13 is between 180° and 215°. This angle range can increase the contact range between the lint cotton and the second spike 19. When it is less than this angle range, there will be some lint cotton that cannot be effectively cleaned; when it is greater than this angle range, since one end of the semi-enclosed grid 13 is connected to the conveying channel 3 and the other end is connected to the discharge channel 4, there may be a phenomenon that the connection section affects the input of the lint cotton into the secondary cleaning bin 2 or the discharge from the secondary cleaning bin 2.

[0047] A second impurity box 7 is installed on the lower side of the semi-enclosed grid 13. Combining Figure 1 As shown, a discharge baffle 5 is installed between the second impurity box 7 and the first impurity box 6, saving installation space; the discharge baffle 5 has an inclined section and a vertical section. Its inclined section is connected to one end of the grid assembly 12, and the inclined section can play a role in collecting the impurities discharged from the primary cleaning bin 1 into the first impurity box 6 and the impurities discharged from the secondary cleaning bin 2 into the second impurity box 7, that is, it plays a guiding role; the vertical section plays a role in separating the two impurity boxes.

[0048] The outlets of the first impurity box 6 and the second impurity box 7 both correspond to the upper part of the impurity discharge bin 8, so that the impurities in the two impurity boxes are collected into the same impurity discharge bin 8 for treatment. A discharge auger 9 is installed in the impurity discharge bin 8 to discharge the impurities from the primary treatment and the secondary treatment.

[0049] The unginned cotton enters the first cleaning bin 1 of the unginned cotton cleaner through the feed inlet 21, and moves forward in a wavy motion under the action of the first spike roller assembly 10 with multiple large spikes and small diameters, which plays a good role in loosening the agglomerated unginned cotton and facilitates the separation of dust and impurities from the unginned cotton. Since the unginned cotton runs above the first spike roller assembly 10, it no longer allows the agglomerated unginned cotton with a high impurity content to run in the channel formed by the spike roller and the grid bar, avoiding damage to important components such as the spike roller and the grid bar; moreover, since the length of the first spike 17 is relatively long, the space formed between the grid bar unit 20 and the root of the first spike 17 is relatively large, and the loosening effect of the unginned cotton is better.

[0050] The unginned cotton that enters the second cleaning bin 2 is hooked and pulled by the second spike 19 into the channel formed by the second spike roller assembly 11 and the semi-surrounding grid bar 13. Under the combined action of the semi-surrounding grid bar 13 and the second spike 19, the unginned cotton and impurities are separated again, and most of the unginned cotton forms single unginned cotton and enters the discharge channel 4.

[0051] This embodiment mainly includes two cleaning bins, which jointly complete the entire cleaning process; and the impurity bins of the two share a discharge baffle 5, which guides the impurities on both sides at the same time, and then is finally discharged outside the machine body through the shared discharge auger 9. This structural method can not only reduce the number of uses of the discharge baffle 5 and the discharge auger 9, save the installation space, but also shorten the travel of the unginned cotton cleaning and processing flow.

[0052] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
