Description

TECHNICAL FIELD

[0001] The present application relates to an inclined seed cotton cleaner, and also relates to a spike roller. BACKGROUND

[0002] The seed cotton cleaner implements the national standard GB / T 19818-2005, the standard name is "seed cotton cleaner" (hereinafter referred to as the standard), the standard implementation date is September 1, 2005, which has been more than eighteen years. The standard specifies the overall performance of the seed cotton cleaner, including the impurity removal efficiency of not less than 50%, the dead boll cotton removal efficiency of not less than 70% (special dead boll cotton seed cotton cleaner), and the shell removal efficiency of not less than 85% (special net type seed cotton cleaner). With the current situation of the transfer of labor force to cities, compared with 2005, the current rural labor force is very scarce, and the mechanization rate of seed cotton harvesting is increasing year by year. Compared with manual picking, for example, the seed cotton harvested by a cotton picker has a relatively high impurity rate, and the front process equipment in the cotton processing production line has higher requirements. The front process equipment includes the seed cotton cleaner.

[0003] The working mode of the existing seed cotton cleaner can be seen in Chinese patent document CN203820936U, which discloses an inclined seed cotton cleaner, which includes a group of six spike rollers arranged obliquely on a frame body, and a group of grid bars obliquely arranged on the frame body. The grid bars correspond one-to-one to the spike rollers (now commonly known as spike rollers). The cotton inlet is located on the upper side of the lower end of the inclined seed cotton cleaner in the inclined direction. The seed cotton is rolled down by the first spike roller at the lower end after entering, and is poked and played in the space between the spike roller and the grid bar, and moves relative to the grid bar, that is, a rubbing and rubbing action is generated, and the impurities fall through the gap between the grid bars.

[0004] In the traditional inclined cleaner, the distance between the spike roller and the grid bar is very small, so as to meet the requirements of impurity separation under the double actions of poking and playing of the spike roller and rubbing and rubbing of the seed cotton flow with the grid bar during the movement. Under this condition, the seed cotton is subjected to various forces, and is prone to entanglement of cotton fibers, and forms "rope silk". As for rope silk, it is known that it refers to a fiber bundle in the form of a strip, which is difficult to pull apart longitudinally with hands due to the close entanglement of cotton fibers, and is commonly known as radish silk. Rope silk seriously affects the quality of lint, and the amount of rope silk in the cotton processing process should be reduced as much as possible.

[0005] In addition, the existence of rope silk also indicates that cotton fiber entanglement is common during the seed cotton cleaning process, which may cause some impurities such as cotton stalks and cotton leaves to be wrapped by entangled cotton fibers, and thus it is difficult to be removed, thereby affecting the appearance of lint.

[0006] Currently, inclined seed cotton cleaning machines generally use a method where the seed cotton passes under a spiked roller. The inventors believe that this conventional method inevitably results in a large number of strands, unless the method of passing the cotton under the roller is modified to reduce the possibility of cotton fibers entangled in the confined space. Therefore, the inventors believe that it is necessary to explore a new seed cotton cleaning principle to fundamentally solve the inherent drawback of seed cotton cleaning, which requires the roller to be deployed in a relatively small space. Summary of the Invention

[0007] The object of the present invention is to provide an inclined seed cotton cleaning machine which is not prone to producing ropes while ensuring good cleaning efficiency. The present invention also provides a spike roller suitable for the inclined seed cotton cleaning machine.

[0008] A first aspect of an embodiment of the present invention provides an inclined seed cotton cleaning machine, the basic structure of which includes:

[0009] The cleaning box is an inclined box body with a communication port on the lower side, a cotton inlet on the upper side of the lower end of the box body, and a cotton outlet on the upper end;

[0010] The pricking roller group is located in the cleaning box body and arranged along the oblique direction of the cleaning box body; the top circle diameter of the pricking roller of the pricking roller group is 359~419mm, and the pricking length of the pricking roller is 70~100mm;

[0011] A transmission mechanism for transmitting the power between the pricking rollers in the pricking roller group so that the pricking rollers rotate in the same direction and the linear velocity nodes on the upper sides of the pricking rollers, which are parallel to the arrangement direction of the pricking roller group, are oriented obliquely upward; and

[0012] The impurity box is located at the lower side of the cleaning box and receives the communicating port to receive the cleaned impurities.

[0013] Optionally, a lattice grille is provided at the communication opening or on the upper side of the communication opening.

[0014] Optionally, except for the lowest pricking roller in the pricking roller group, the remaining pricking rollers are each equipped with a grid bar;

[0015] The axis of the distribution cylinder of the lattice bars in the lattice grid is collinear with the axis of the corresponding spike roller.

[0016] Optionally, the cleaning box is provided with a pair of debris outlets on the lower side of the position where it is aligned with the nail roller at the lower end;

[0017] Correspondingly, a door panel and a corresponding door panel opening and closing structure are provided to match the auxiliary miscellaneous outlet.

[0018] Optionally, the door panel is a column panel, and the axis of the column panel is colinear with the axis of the nail roller located at the lowermost end.

[0019] Optionally, the upper side of the door panel is hinged to the outer side of the upper edge of the auxiliary outlet, and a lock portion is provided on the lower side of the door panel and the outer side of the lower edge of the auxiliary outlet in an aligned manner.

[0020] Optionally, the number of the pricking rollers in the pricking roller group is 12 to 20.

[0021] Optionally, the diameter of the spikes in the spike roller set is 9 to 18 mm;

[0022] The spikes on the spike roller are arranged circumferentially on the roller, with a total of 6 to 8 rows;

[0023] The spacing between spikes in the same row is 50~150mm.

[0024] Optionally, at least one dust removal port is provided on the upper side of the cleaning box.

[0025] According to a second aspect of the embodiments of the present invention, a spike roller is provided, which is suitable for the inclined seed cotton cleaning machine provided in the first aspect of the embodiments of the present invention. The top circle diameter of the spike roller is 359~419mm, and the spike length of the spike roller is 70~100mm.

[0026] Traditional seed cotton cleaning machines generally adopt a bottom-feeding method, that is, the seed cotton flow is located between the spike rollers and the grid bars. In the embodiment of the present invention, an top-feeding method is adopted. Specifically, the direction of the spike rollers in the spike roller group is opposite to that of the traditional seed cotton cleaning machine. In addition, unlike traditional seed cotton cleaning machines, the embodiment of the present invention uses relatively small spike rollers and relatively long spikes, which have a better beating effect on the seed cotton. Because the seed cotton flow of the seed cotton cleaning machine according to the embodiment of the present invention passes above the spike rollers, the main cleaning method is beating, rather than traditional rubbing and friction. The threading situation is almost invisible, and the cleaning efficiency meets the requirements of national standards. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] It should be understood that the inclined seed cotton cleaner is a common seed cotton cleaner, but not the only seed cotton cleaner. When evaluating different seed cotton cleaners, there are different evaluation methods for the removal efficiency. For example, some seed cotton cleaners focus on the removal of foreign fibers, some focus on the removal of bolls, and some focus on the removal of dead petals. However, for example, the seed cotton cleaner specially used for removing dead petals can also remove some other impurities in the process of removing dead petals. The inclined seed cotton cleaner is the same, although it is currently mainly used for cleaning cotton leaves and dust.

[0035] Therefore, the inclined seed cotton cleaner provided in the embodiment of the present application focuses on the removal of cotton leaves and dust, but also has a certain cleaning effect on some heavy impurities such as dead petals, mud blocks, and stones.

[0036] For the inclined seed cotton cleaner, the inlet 9 is usually located on the upper side of the lower end of the cleaning box. The seed cotton is introduced from the inlet 9 and gradually moves upward by being hit by the spikes. In the traditional inclined seed cotton cleaner, the gap between the spike roller 7 and the lattice grid 4 is the channel for the seed cotton flow, so that the seed cotton flow is hit and rolled by the spikes in the process of moving upward. Figure 1 For example, if it is configured as a traditional seed cotton cleaner, the spike roller 7 needs to rotate clockwise in the state illustrated in the embodiment, and the spike roller 7 located at the lower right end will roll the seed cotton introduced from the inlet 9 into the lower side of the spike roller 7, and cooperate with the lattice grid 4 to roll and hit the seed cotton flow, so as to achieve cleaning. In order to distinguish, the traditional inclined seed cotton cleaner is called a downward cotton mode. Figure 1

[0037] ​In the embodiment of the present application, the seed cotton flow is made to flow above the spike roller 7 by changing the direction of the spike roller 7, and the main form of cleaning is the beating of the spike roller 7 to the seed cotton. Through the trial use of the prototype, it is found that although a small amount of seed cotton will also enter below the spike roller 7, it is not enough to form a seed cotton flow below the spike roller 7, and the small amount of seed cotton entering below the spike roller 7 will generally be rolled back onto the spike roller 7 by the spike roller 7, thereby forming an up-going cotton mode different from the existing inclined seed cotton cleaner.

[0038] Compared with the traditional inclined seed cotton cleaner, the function of the grid 4 in the embodiment of the present application is different. In the traditional inclined seed cotton cleaner, the grid 4 mainly cooperates with the spike roller 7 to achieve rubbing and beating of the seed cotton flow, and therefore the grid 4 has strict order. In the embodiment of the present application, the function of the grid 4 has been weakened to only need to play a sorting role, and no longer cooperates with the spike roller 7 to achieve cleaning. Therefore, in the embodiment of the present application, the grid 4 can be completely replaced by a screen, thereby being different from the traditional grid 4 in structure. It can also be known that the embodiment of the present application only uses the concept of the traditional grid 4, but does not have the inherent properties of the traditional grid 4, and only has the sorting properties. In other words, the term grid 4 does not limit it to having the structure or configuration of the traditional grid 4, and can further include a screen and other components having sorting capabilities.

[0039] In the traditional inclined seed cotton cleaner, the seed cotton flow advances by rolling in the gap between the spike roller 7 and the grid 4, and is easy to form a strand. In the embodiment of the present application, the up-going cotton mode is achieved, and no longer has the rubbing condition, and will not form the rolling advancing form, thereby weakening the condition of the strand formation in the seed cotton cleaning process. It is found through verification that based on the up-going cotton mode, the strand is almost invisible.

[0040] As the inclined seed cotton cleaner in the embodiment of the present application is the same as the traditional seed cotton cleaner in structure, it has a cleaning box, a spike roller group, a transmission mechanism and a foreign matter box, and is the same in basic configuration. In order to adapt to the up-going cotton, first of all, the transmission mechanism satisfies the up-going cotton form as a normal state, and at the same time, since the rubbing and beating is changed to simple beating, the parameters of the spike roller 7 are also different from the prior art.

[0041] The main components of the inclined seed cotton cleaner in the embodiment of the present application will be described one by one below. The cleaning is mainly completed in the cleaning box, and the cleaning box is in the structure of an upper part being a roughly inclined rectangular cabin in the structure shown in the drawings, Figure 1 and Figure 3 and Figure 4 is shown in a horizontal manner for convenience of observation.

[0042] The main component of the cleaning is the set of spike rollers, in Figure 1 and Figure 4 In the example structure, there are sixteen spike rollers 7, while a conventional inclined seed cotton cleaner usually has only six spike rollers 7.

[0043] In the embodiment of the present application, the spike roller 7 in the set of spike rollers is smaller than the conventional spike roller 7. In the case of a smaller spike roller 7, the spike 25 arranged thereon is a long spike, which will be described in detail below, and will not be described here again.

[0044] However, as for the number of spike rollers 7, in the case of a smaller spike roller 7, which means that the top circle diameter of the spike roller 7 is smaller, compared with the general case that the conventional inclined seed cotton cleaner is generally equipped with six spike rollers 7, in the embodiment of the present application, at least twelve spike rollers 7 are arranged, and the number of spike rollers 7 should not be more than twenty. Compared with the conventional inclined seed cotton cleaner, the inclined seed cotton cleaner of the present application using the up-going cotton has a relatively lower cleaning efficiency under the condition of the same number of spike rollers 7. Generally, at least twelve spike rollers 7 are arranged, but when the number of spike rollers 7 is too large, the cleaning efficiency does not increase significantly. It is found through adjustment tests that when the number of spike rollers 7 is sixteen, the cleaning efficiency of cotton leaves and dust is the highest, although there are some other factors, such as the properties of the seed cotton, such as the moisture absorption rate, etc., but sixteen is relatively more appropriate.

[0045] In addition, compared with the known spike roller 7, the distribution density of the spikes 25 on the spike roller 7 of the inclined seed cotton cleaner suitable for the embodiment of the present application is relatively small, or relatively sparse, and the spikes 25 are longer. In some embodiments, the spikes 25 on the spike roller 7 are arranged in 6-8 rows in the circumferential direction of the roller cylinder of the spike roller 7. The number of rows is reduced, and the spacing of the spikes 25 in the same row is increased. The recommended spacing is 50-150 mm, and the preferred spacing is 90 mm.

[0046] And preferably, as Figure 6 shown, the spikes 25 in adjacent rows are staggered, rather than located on the same circumference.

[0047] The cleaning box is inclined in the inclined seed cotton cleaner, so as to match the "inclined". The cleaning box is generally a sheet metal box body, and can have wall plates at the left and right ends, and the rest of the box body is made of sheet metal.

[0048] It should be known that in the field of cotton processing machinery, the direction corresponding to the spoke is the width direction, and the spoke is Figure 6 In the example structure, it is determined by the axial length of the baffle plate 24 in the drawing, in other words, the width of the cleaning. The width direction corresponds to the left-right direction, and is also commonly referred to as the transverse direction.

[0049] The arrangement direction of the spike roller 7 corresponds to the horizontal direction, which is usually called the length direction or the longitudinal direction.

[0050] The inclined arrangement of the cleaning box does not affect the cognition of the two ends, especially the two ends determined based on the length direction and the left and right sides determined based on the machine beam.

[0051] The lower side of the cleaning box has a communication port for guiding out the impurities cleaned by the spike roller group. The cleaning box also has determined upper and lower ends in the inclined state, that is, the right end shown in Figs. 7 and 8, and the upper side of the end is provided with the cotton inlet 9, and the opposite end, that is, the upper end of the cleaning box is provided with the cotton outlet 5. In the working state, the seed cotton flows in the spike roller group, and the spike roller 7 is sequentially thrown and gradually moves upward until it is guided out from the cotton outlet 5. Figure 3 Figure 4

[0052] It is worth mentioning that the traditional inclined seed cotton cleaner mainly relies on the throwing of the spike roller 7 and the rubbing with the grid 4, and the seed cotton opening effect is not good. In some cotton processing production lines, a special opening roller is usually configured. In the embodiment of the present application, the cleaning process is also the opening process. The spike roller group sequentially throws the seed cotton to produce an opening effect. In the traditional inclined seed cotton cleaner, the seed cotton flows in the narrow gap between the spike roller 7 and the grid 4 based on the throwing power and gradually moves upward. The throwing and cleaning effect is weak, the rubbing and cleaning effect is relatively strong, and it is difficult to achieve the opening of the seed cotton.

[0053] Based on the different considerations from the traditional inclined seed cotton cleaner, the spike roller group configured in the embodiment of the present application is also arranged in the cleaning box body and arranged along the inclined direction of the cleaning box body. However, the spike roller 7 configured in the embodiment of the present application adopts a relatively small spike roller 7. The spike roller 7 is small, but the spike 25 on the spike roller 7 is longer than the spike 7 of the traditional spike roller 7. The specific structural parameters of the spike roller group in the embodiment of the present application are as follows: the top circle diameter of the spike roller 7 is 359-419 mm, and the length of the spike of the spike roller 7 is 70-100 mm.

[0054] Regarding the upward cotton method, the inventor has made various attempts. When the upward cotton method is first proposed and verified by using the traditional spike roller 7, the impurity removal effect is not good, the cleaning efficiency of the cotton leaves is less than 30%, and the cleaning efficiency of the dust is less than 60%. By reducing the top circle diameter of the spike roller 7 and lengthening the length of the spike, the cleaning efficiency is obviously improved. The cleaning efficiency of the cotton leaves can reach more than 50%, and the cleaning efficiency of the dust is higher than 75%.

[0055] ​​Since the up-and-down cotton picking mode is just proposed, the structural parameters and process parameters of the inclined seed cotton cleaning machine still have a relatively large adjustment space, although some performance indicators are not as good as those of the traditional inclined seed cotton cleaning machine, but it may represent a new technical route for seed cotton cleaning. Especially in dealing with the defect that the traditional seed cotton cleaning machine produces more lint, it has obvious improvement.

[0056] The driving of the spike roller group will be briefly described below. First, the transmission, the specifications of the spike rollers 7 in the spike roller group are usually the same, and the working modes are basically the same, mainly the turning direction and the rotating speed are basically the same, therefore, for the spike rollers 7, the transmission is usually based on a synchronous mechanism. Different from the traditional inclined seed cotton cleaning machine, the turning direction of the spike rollers 7 in the seed cotton cleaning machine based on the embodiment of the present application is opposite to that of the spike rollers 7 in the traditional inclined seed cotton cleaning machine, that is, the spike rollers 7 in the seed cotton cleaning machine based on the embodiment of the present application are counterclockwise, while the spike rollers 7 in the traditional inclined seed cotton cleaning machine are clockwise. Figure 1 For example, if the traditional spike roller 7 is configured, it should rotate clockwise, while in the embodiment of the present application, the spike roller 7 rotates counterclockwise in the state shown in FIG. 7, so that after the seed cotton enters the inlet 9, the seed cotton will be thrown to the left and up. While the traditional inclined seed cotton cleaning machine, because the spike roller rotates clockwise in the structure shown in FIG. 1, the seed cotton will be rolled into the spike roller 7 below, which is the essential difference from the embodiment of the present application. Figure 1 For example, if the traditional spike roller 7 is configured, it should rotate clockwise, while in the embodiment of the present application, the spike roller 7 rotates counterclockwise in the state shown in FIG. 7, so that after the seed cotton enters the inlet 9, the seed cotton will be thrown to the left and up. While the traditional inclined seed cotton cleaning machine, because the spike roller rotates clockwise in the structure shown in FIG. 1, the seed cotton will be rolled into the spike roller 7 below, which is the essential difference from the embodiment of the present application. Figure 1 For example, if the traditional spike roller 7 is configured, it should rotate clockwise, while in the embodiment of the present application, the spike roller 7 rotates counterclockwise in the state shown in FIG. 7, so that after the seed cotton enters the inlet 9, the seed cotton will be thrown to the left and up. While the traditional inclined seed cotton cleaning machine, because the spike roller rotates clockwise in the structure shown in FIG. 1, the seed cotton will be rolled into the spike roller 7 below, which is the essential difference from the embodiment of the present application.

[0057] As a more accurate description, in the embodiment of the present application, the turning direction of the spike roller 7 in the spike roller group is taken as the reference of the arrangement direction of the spike roller group, then the linear velocity direction corresponding to the upper side generatrix of the spike roller 7 should be parallel to the arrangement direction of the spike roller group, which is actually the plane where the shaft axes of the spike rollers in the spike roller group are located, and the linear velocity direction is obliquely upward, which is different from the obliquely downward in the prior art.

[0058] Figure 3 Sixteen shafts are shown in FIG. 6, corresponding to sixteen spike rollers 7, the part for transmission of the shaft on the rightmost side is not shown, the part for transmission is divided into left and right two groups according to the left and right sides of the inclined seed cotton cleaning machine (here, the left and right correspond to the left and right determined by the machine arms), and the three shafts on the left in the figure, on the side shown in the figure, assuming that this side is the left side of the inclined seed cotton cleaning machine, then the two shafts on the left in FIG. 6 are driven by the synchronous belt mechanism 11, the synchronous belt mechanism 11 for driving the second and third shafts is located on the other side, that is, the right side of the inclined seed cotton cleaning machine, to avoid interference, and the driving of the remaining spike rollers 7 is sequentially similar. Figure 3

[0059] ​The driven pulley 14 in the middle is used to introduce power and is connected to, for example, an electric motor via a belt transmission mechanism. The pulley shaft of the driven pulley 14 corresponds to a thorn roller shaft, and the other end of the thorn roller shaft is used to transmit power to the two thorn rollers 7 on the left and right sides via a synchronous belt mechanism 11.

[0060] Figure 3 The pulley shaft 13 is also the nail roller shaft, and those skilled in the art should have a clear understanding.

[0061] Figure 3 The synchronous belt mechanism 11 can also be replaced by a transmission mechanism such as a chain transmission mechanism, a gear transmission mechanism, etc. The chain transmission mechanism is similar to the synchronous belt mechanism 11, but the gear transmission mechanism needs to consider the spacing of the spike roller shaft, and may need to be configured with relatively large gears, and the gears need to be lubricated, which is not as simple as the synchronous belt mechanism 11.

[0062] The lower side of the cleaning box is connected to the impurity box by, for example, a flange. Figure 1 The box structure corresponding to the middle receiving hopper 3, the upper opening of the cleaning box is connected to the communication port, so that the settled impurities cleaned out by each spike roller 7 are enriched through the receiving hopper 3, for example.

[0063] As mentioned above, in the traditional inclined seed cotton cleaning machine, the pricking roller 7 and the grid 4 have a definite and strict matching relationship to achieve the rubbing and beating of the seed cotton. However, in the embodiment of the present invention, the concept of the grid 4 is borrowed to facilitate the understanding of those skilled in the art. However, due to the adoption of the upper cotton walking method, the role of the grid 4 in the traditional context has been weakened and has served as a component selection component. Therefore, the grid 4 in the embodiment of the present invention actually includes a sieve plate or a similar structure, such as a filter screen, a porous plate, etc.

[0064] In addition, since the gap between the grating 4 and the spiked roller 7 in conventional inclined seed cotton cleaning machines is used for the passage of the seed cotton flow, the gap is relatively large and should be sufficient to allow the seed cotton flow to pass through. However, in the embodiments of the present invention, the gap between the grating 4 and the spiked roller 7 can be relatively small, in principle, so as not to cause motion interference.

[0065] Furthermore, under the condition that no motion interference occurs, given that some heavy debris, such as stones, may fall onto the lattice 4 and become lodged there and unable to move downward, if the distance between the spike roller 7 and the lattice 4 is too small, a rigid collision may occur, damaging the bars of the lattice 4 and the spikes 25 on the spike roller 7. Therefore, in a preferred embodiment, the distance between the top circle of the spike roller 7 and the bars of the lattice 4 should not be less than 8 mm, nor greater than 15 mm, with 12 mm being preferred.

[0066] It should be noted that the top circle of the spike roller 7 refers to the distance between the spike top of the spike 25 and the axis of the spike roller.

[0067] In addition, if the distance between the top circle of the spike roller 7 and the bars of the bar grid 4 is too large, it is possible that some of the rolled seed cotton cannot be rolled out again, and the accumulation of seed cotton will affect the impurity removal. Therefore, the distance should not be greater than 15 mm.

[0068] Therefore, compared with the strict distance limitation between the bar grid 4 and the spike roller 7 of the traditional inclined cleaner, the distance limitation in the embodiment of the present application is relatively loose, and the sorting component of the communication port can be directly constructed in position, or it can be slightly set upward to form the cooperation relationship with the spike roller 7 as described above.

[0069] In the embodiment of the present application, if the bar grid 4 still adopts the traditional structure of the bar grid 4, since the bars do not participate in the rubbing and beating of the seed cotton, the rigidity requirement of the bars and the assembly reliability of the bars on the bar grid 4 are greatly reduced, and therefore the shape requirement of the bars is greatly reduced. The bars can be cylindrical or rectangular in cross section, or can be in the form of a sheet or a wire.

[0070] In addition, since the traditional bars are parallelly arranged and lack of connection points, in the embodiment of the present application, it is not necessary to consider the necessity of parallel arrangement and the reduction of connection points. In other words, the bars can be connected by longitudinal ribs, thereby forming a mesh-shaped sieve hole.

[0071] Therefore, it can be seen that the bar grid 4 in the embodiment of the present application essentially comprises a mesh plate such as the aforementioned sieve plate, which is obviously different from the bar grid 4 in the context of the traditional inclined seed cotton cleaner.

[0072] Since the more uniform the gap between the bar grid 4 and the spike roller 7 is, the more easily the seed cotton falling into the gap can be rolled onto the spike roller 7 by the spike roller 7, therefore, the spike roller group is adapted in that, except for the spike roller 7 at the lowermost end, each of the remaining spike rollers 7 is provided with a bar grid 4; correspondingly, the axis of the distribution column surface of the bars in the bar grid 4 is collinear with the axis of the corresponding spike roller 7, thereby forming a relatively uniform gap in the thickness of the spike roller 7.

[0073] Further, the cleaning box is provided with a pair of impurity outlet on the lower side of the position matched with the lowermost needle roller 7, and some heavy impurities are most likely to drop out when colliding with the first needle roller 7 and falling below the first needle roller 7 when entering from the cotton inlet 9, and some of the heavy impurities may exceed the sorting capacity of the grid 4, therefore, the door plate is matched with the pair of impurity outlet, and the corresponding door plate opening and closing structure is provided to discharge some heavy impurities.

[0074] In Figure 2 In the example structure, the door plate is constructed by the flap 10 shown in the figure, and the left side of the flap 10 can be installed by the hinge shaft to become a side-hinged door structure. The right side of the flap 10 can be configured by, for example, a latch structure to configure the door plate opening and closing structure. Based on this, those skilled in the art can easily determine other types of doors and door plate opening and closing structures, which will not be described here.

[0075] Further, the door plate is a cylindrical plate, and the axis of the cylindrical plate is collinear with the axis of the lowermost needle roller 7.

[0076] It should be noted that, for example, the door plate of the flap 10 can be a fully closed structure, or can be similar to the structure of the grid 4, and relatively small impurities directly drop out, and relatively large impurities can be temporarily stored. And the cleaning box can be provided with a window 16 on the side of the position of the flap 10 to observe the storage of materials on the flap 10.

[0077] In addition, the auxiliary impurity outlet can be connected with an auxiliary impurity box, and the control of the flap 10 can use an indirect control method, for example, using a swing cylinder to drive the opening and closing of the flap 10, and when the operator observes that the flap 10 stores more materials, the swing cylinder is started to open the flap 10 to discharge the heavy impurities.

[0078] Regarding the impurity outlet, Figure 1 In the cleaning box, the impurity box is provided on the lower side, and the impurity box is also the inherent configuration of the inclined seed cotton cleaner, and is generally in the form of a hopper, such as Figure 1 The material collecting hopper 3 is used to enrich the materials. The impurity discharging auger 2 is provided at the lower end of the material collecting hopper 3 to guide the materials enriched by the material collecting hopper 3.

[0079] The impurity outlet includes three parts, the impurities discharged from the auxiliary impurity outlet, the impurities discharged from the communication port, and the dust. As known from the foregoing description of the principle of the inclined seed cotton cleaner, the inclined seed cotton cleaner based on the embodiment of the present application mainly performs cleaning by means of throwing and beating, and the dust is not easy to settle due to its large specific surface area, and the settlement does not conform to the purpose of the present application, therefore, Figure 1In the example structure, a dust removal port 8 is arranged on the upper side of the cleaning box. In the figure, there are two dust removal ports 8, but one or more can also be arranged. The dust removal port 8 is connected to a dust removal device, such as a cyclone dust collector.

[0080] The dust removal port 8 is used to suck out dust in the form of air suction. The dust removal device can be provided with an air blower. In addition to, for example, a cyclone dust collector, it can also be further provided with, for example, a bag dust collector, etc.

[0081] Figure 4 And Figure 5 In the above, the upper panel of the cleaning box is provided with a plurality of maintenance openings, and the periphery of the maintenance opening is provided with a bearing platform 17. The cover plate 15 can be placed on the bearing platform 17 and then locked.
