Description

Technical Field

[0001] This invention relates to a waste removal assembly for a cotton cleaning machine, and also to a cleaning machine equipped with the waste removal assembly. Background Technology

[0002] Currently, there are many types of cotton cleaning machines, but those that use removal blades include both seed cotton cleaning machines and lint cotton cleaning machines, although only a small portion of seed cotton cleaning machines utilize removal blades. The main targets of removal blades are boll shells and cotton stalks—imperfections that are easily entangled with cotton fibers but have a higher specific gravity than seed cotton or lint. Utilizing centrifugal force, for example, during the high-speed rotation of a licker-in roller, the relatively heavier impurities are positioned on the outer side of the cotton layer and are drawn into the cotton fibers entangled with them. The removal blades are arranged in an arc shape on the outer side of the licker-in roller; ideally, the axis of this arc is collinear with the axis of the licker-in roller. The cotton fibers carrying impurities, for example, are blocked in the middle by the removal blades, causing them to bend. This sudden increase in resistance eventually exceeds the pulling capacity of the cotton fibers, allowing the impurities to be discharged through the gaps between adjacent removal blades.

[0003] Because different raw materials, namely seed cotton, have varying impurity levels and compositions, the cleaning effect will differ even when using a cleaning machine with a debriding blade, even if the same machine is used. Furthermore, the debriding blade may damage the cotton fibers; therefore, performing heavy cleaning when it's unnecessary will inevitably have negative effects. The inventor believes that using different cleaning capabilities for different types of cotton is of substantial importance. Summary of the Invention

[0004] The purpose of this invention is to provide a waste removal assembly with adjustable waste removal capacity. This invention also provides a cleaning machine equipped with the waste removal assembly.

[0005] According to a first aspect of the present invention, a waste removal assembly is provided for use in a cotton cleaning machine, the waste removal assembly comprising:

[0006] The debris removal tool assembly includes a debris removal tool, the rake face of which defines the debris removal area;

[0007] The impurity removal zone adjustment assembly includes an end seat corresponding to each end of the impurity removal blade, a shielding member mounted on the end seat and arranged parallel to the impurity removal blade, and a rotating shaft rotatably mounted on the rear side of the impurity removal blade, the axis of the rotating shaft being parallel to the impurity removal blade; and

[0008] A driving component is used to drive the end seat to rotate so that the end seat can be adjusted within a predetermined angle range; the angle range is determined by the first stop when the shielding component shields the rake face and the second stop at the maximum angle position of the end seat.

[0009] Optionally, the end seat is an L-shaped end plate;

[0010] The rotating shaft is located at the lower rear side of the tool holder of the waste removal tool assembly;

[0011] At the first stop position, one arm of the L-shaped end plate extends from the pivot to the rear side of the front blade face; the other arm extends from the rear side of the front blade face to the cutting edge of the waste removal knife.

[0015] If the shielding component is a rod-shaped component, the vertical projection of the rod-shaped component on the rake face is located within the rake face.

[0016] Optionally, when the shielding component is a rod-shaped component, the rod-shaped component is a cylindrical rod;

[0017] The cylindrical rods are two or three in number and are arranged in the direction of extension of the other arm of the L-shaped end plate.

[0021] When a rotary drive component is used, the rotary drive component is connected to the rotating shaft;

[0022] When a linear drive component is used, the rotating shaft forms the pivot of a crank arm assembly, which also includes a drive arm that is perpendicularly connected to the rotating shaft.

Furthermore, the waste removal adjustment component adopts an angle adjustment method, which is convenient to adjust, and the angle adjustment is a relatively easy adjustment method to implement, and the adjustment accuracy is also easy to control.

[0048] Online monitoring of cotton quality is a relatively mature technology. Therefore, the embodiments of this invention focus on how to adjust it, rather than how to detect cotton quality online. Although the automatic adjustment of the impurity removal assembly needs to be adjusted according to the cotton quality, it should also be known that the quality grade of seed cotton in the same batch often does not fluctuate much. Therefore, the adjustment of the impurity removal assembly can be done manually, but it is preferred to use an automatic method. This is because even seed cotton from the same cotton mill may have a large range of mixing due to the way cotton is piled up.

[0049] Therefore, in the embodiments of the present invention, the relationship between cotton quality and the impurity discharge area is known. However, the cotton quality detection is not described in the embodiments of the present invention. The present invention focuses on the adjustable impurity discharge area, which should be clearly understood by those skilled in the art.

[0050] It should be understood that cotton cleaning machines mainly include seed cotton cleaning machines and lint cotton cleaning machines. Among them, the use of waste removal blades is relatively common in lint cotton cleaning machines, while it is used in a smaller number of seed cotton cleaning machines. However, the usage of waste removal blades is roughly the same in both seed cotton cleaning machines and lint cotton cleaning machines. Therefore, the configuration of waste removal blades in the cleaning machines will only be briefly described in the embodiments of this invention.

[0051] Specifically, such as Figure 1As shown, the waste removal blades are generally arranged in an arc shape at a position no more than half the circumference on the outer side of one side of the licker roller 4. The number of waste removal blades on each cleaning machine varies, generally ranging from five to twelve, but usually no more than nine, but generally no less than six.

[0052] The distance between the blade of the waste removal knife and the licker roller 4 is usually determined according to the equipment model and processing requirements, and is generally between 0.8 and 2 mm. This is common knowledge in the field. Since it is not an improvement direction of this invention, the determination and adjustment of the distance between the blade of the waste removal knife and the licker roller 4 will not be elaborated here.

[0053] The debris removal blade is generally a blade strip, which is arranged laterally on the cleaning machine. It should be noted that in the field of cleaning machine technology, the lateral direction is the direction of the machine's spokes, also known as the left-right direction. The length of the blade strip depends on the machine's spokes and is related to the width of the cleaning machine's body.

[0054] Within the reference plane, the direction perpendicular to the tool bar is the longitudinal direction, also known as the front-to-back direction.

[0055] In addition, the cleaning machine is a three-dimensional structure, so it also has a third dimension, namely height.

[0056] In embodiments of the present invention, unless otherwise stated, the basic reference system is based on the basic reference system of the cleaning machine.

[0057] However, it should be understood that a tool for removing miscellaneous debris has a defined front face, cutting edge, and back face, and is based on its own unique reference system. Within this system, there are specific designations, such as the front and back faces, which are not named according to the front or back of the blade. Generally, the front and back faces are used to define the cutting edge; in other words, the intersection of the front and back faces is the cutting edge. However, the side opposite the cutting edge is called the back of the blade, thus creating another orientation: the side opposite the cutting edge can also be called the rear side or back side. The side where the cutting edge is located is the front side. The front and back faces are named using other methods, and have specific definitions within the field of cutting tools.

[0058] Generally speaking, the rake face of the tool defines the waste removal area. Figure 1 In the middle, the position of the debris removal rod assembly 3 shown by the double-dotted line is when the debris removal rod assembly 3 is relatively far away from the front face of the debris removal knife. At this time, the shielding effect on the debris removal area is the weakest, and the debris removal ability is the strongest.

[0059] As the debris removal rod assembly 3 gradually approaches and eventually engages with the rake face, the debris removal area gradually decreases, and the debris removal capability gradually weakens. The solid line in the figure shows the position of the debris removal rod assembly 3 at its minimum debris removal capability.

[0060] Figure 1Wall panel 1 is the frame wall panel, which is the main mounting base for other components on the cleaning machine, such as the waste removal knife assembly 2. It has waste removal knife seats at both ends, which are generally fixed to the wall panel at the corresponding ends by means of waste removal knife seats using, for example, hexagon socket head cap screws or bolts.

[0061] The waste removal blade assembly 2 is generally made according to Figure 1 The illustrated arrangement is on one side of the licker roller 4, and to achieve relatively high rigidity, it often has a relatively large thickness. The thickness is generally a dimension determined by the normal direction of the front blade, rather than the so-called front-to-back distance.

[0062] And such Figure 1 As shown in the figure, the solid line indicates that the impurity removal rod assembly 3 is located at the front blade of the impurity removal knife in the impurity removal knife assembly 2. The function of the blade of the impurity removal knife is basically completely covered. At this time, the function of the impurity removal knife is very weak, but the impurity removal function of the impurity removal rod assembly 3 is enhanced. The impurities pulled by the cotton fibers that follow the rotation of the licker-in roller 4 may first come into contact with the impurity removal rod assembly 3, producing a throwing effect.

[0063] from Figure 1 As can be seen from the illustrated structure, the shape of the waste removal blades at different positions varies slightly. In some implementations, the angle between the front face of each waste removal blade and the center line of the piercing roller 4 at the blade edge as shown in the figure may also be different. However, it should be understood that in the embodiments of the present invention, the focus is on the adjustment of the waste removal area, and not on the adjustment of the waste removal blade assembly 2.

[0064] In an embodiment of the present invention, the impurity removal knife assembly 2 has a defined impurity removal area. However, in another embodiment of the present invention, the size of the impurity removal area needs to be adjusted by means of, for example, an impurity removal bar assembly 3, an impurity removal area adjustment assembly, so as to adapt to cotton with different impurity contents.

[0065] In view of this, the impurity removal zone adjustment assembly includes an end seat corresponding to each end of the impurity removal blade and a shielding component mounted on the end seat and arranged parallel to the impurity removal blade. The end seat is used for mounting the impurity removal zone adjustment assembly on the wall plate 1. The purpose of this mounting is to achieve adjustment. The connection method achieved is a dynamic connection. The end seat is mounted on a seat hole opened in the wall plate 1 via a rotating shaft 51. The seat hole can accommodate a bearing, which can be a rolling bearing or a sliding bearing, to allow the rotating shaft 51 to have rotational freedom.

[0066] It should be understood that the impurity removal area adjustment component is the component being adjusted, therefore it needs to have a driving device, referred to as a driving component, to provide the power required for the adjustment of the impurity removal area adjustment component through the rotating shaft 51.

[0067] For ease of description, the driving device will be referred to as the driving component in the following text.

[0068] The rotating shaft 51 is located on the rear side of the waste removal knife. This rear side should be based on the blade of the waste removal knife, that is, the opposite side of the side where the blade is located, or the back side, so that the rotation adjustment of the waste removal area adjustment component has swing space.

[0069] Furthermore, the axis of the rotating shaft 51 is parallel to the waste removal knife.

[0070] Regarding the rotating shaft 51, the rotating shaft 51 connected between the two end seats can be either a through shaft or two "half shafts". The through shaft is more suitable for driving at one end, while the assembly method is more flexible when using two "half shafts". However, when driving, it is necessary to use, for example, the cleaning rod 35 on the cleaning rod assembly 3 to drive the end seat at the other end to rotate together, which will result in a slight torsional deformation.

[0071] As the spokes of cleaning machines become increasingly larger, some even reaching 6000mm in length, the rotating shaft 51 is preferably constructed using a half-shaft in the embodiments of the present invention.

[0072] The length of the half-shaft only needs to be sufficient to allow it to enter the cleaning compartment from outside and reliably connect with the end seat; therefore, the length of the half-shaft can be relatively short.

[0073] Obviously, the adjustment amount of the impurity removal rod assembly 3 does not need to be too large, and the half shaft does not need to rotate, but only needs to swing. Therefore, the driving component is directly or indirectly connected to the end seat to drive the end seat to swing, which is used to adjust the impurity removal area in two directions: expanding or shrinking.

[0074] As mentioned earlier, the adjustment amount of the debris removal rod assembly 3 does not need to be too large, which will inevitably correspond to a swing angle range. In the mechanical field, the angle range can be determined by two stops. One of the stops can be directly determined by the rake face, that is, the debris removal tool can be used as a constraint to determine the first stop. However, in order to avoid rigid impact, the control of the first stop can be controlled by the drive component, rather than by the debris removal tool as a constraint. Therefore, a margin can be set for the first stop. For example, there is an angle difference between the debris removal rod assembly 3 and the rake face at the first stop. This angle difference should be greater than the margin. Assuming that the rotation angle of the debris removal rod assembly 3 corresponding to the first stop is, for example, 0 degrees, and the margin is [-3, 3] degrees, then the angle difference should be greater than 3 degrees.

[0075] Regarding the determination of the second stop position, for example, when the impurity removal rod assembly 3 is in the position as follows: Figure 1The position indicated by the midpoint line indicates that the limitation of the impurity removal rod assembly 3 on the impurity removal knife's impurity removal capability is very small or completely eliminated. Further adjustment to a larger angle is meaningless. After verification, the rotation angle range of the impurity removal rod assembly 3 determined by the first and second stops is relatively suitable when it is around 25 degrees. The maximum should not exceed 30 degrees. When it is greater than 30 degrees, the adjustment effect of the impurity removal rod assembly 3 is basically not significant. If it is too small, for example, less than 20 degrees, the influence of the impurity removal rod assembly 3 is still relatively large, and the impurity removal capability of the impurity removal knife cannot be maximized.

[0076] For ease of description, the state of the debris removal rod assembly 3 at the first stop position is called the original state, the other positions are called the adjustment states, and the state at the second stop position is called the maximum adjustment state. Therefore, the design angle of the debris removal rod assembly 3 at the first stop position can be defined as 0 degrees. Although, as mentioned earlier, the first stop position may be a range, the "design angle" is a constant. Especially when constrained by the debris removal blade, the angle corresponding to the first stop position basically matches the design angle.

[0077] As can be seen from the above, such as Figure 1 As shown, when, for example, the debris removal rod assembly 3 is in the first stop position, that is, when the component marked as debris removal rod assembly 3 in the figure is described by the corresponding solid line in the figure, the debris removal rod assembly 3 covers the front face. For ease of description, the part of the debris removal area adjustment component used to cover the front face at this time is called the covering component.

[0078] It should also be noted that "parallel to the cleaning blade" refers to being parallel to the cutting edge of the cleaning blade in a macroscopic sense. Furthermore, the direction defined by the cutting edge in this field generally refers to the transverse direction, which is also the extension direction of the cleaning blade strip, and should not be understood as any part of the relatively complex geometric cleaning blade assembly 2, but rather as a reference.

[0079] The end seat can be a plate or a rod. Figure 11 One example of an end seat is shown as end plate 34 in the figure. Plates are easy to drill holes in, and the end seat is made of a plate.

[0080] And as Figure 1 and Figure 3 The structure illustrated here has an L-shaped end plate, referred to as an L-shaped end plate. The L-shaped end plate consists of two arms with an included angle of 85-95 degrees, preferably 90 degrees, to facilitate engagement with the rear and upper sides of the waste removal knife assembly. In this case, the rotating shaft 51 is located below the rear side of the waste removal knife assembly's blade holder. Under these conditions, one arm of the L-shaped plate extends from the rotating shaft 51, its length sufficient to position the other arm above the front blade face.

[0081] For ease of description, the arm connected to the rotating shaft 51 is called the first arm, and the arm located above the rake face is called the second arm.

[0082] like Figure 1 and Figure 3 As shown, at the first stop position, the first arm extends from the pivot 51 to the rear side of the front blade face; the second arm extends from the rear side of the front blade face to the cutting edge of the cleaning knife.

[0083] The shielding component can be a plate-shaped component or a rod-shaped component. If a plate-shaped component is used, its main function is shielding, and its own impurity removal function is relatively limited. When a rod-shaped component is used, it also has its own impurity removal function. Even when it is in the first stop position, the cylindrical contour provided by the rod-shaped component can quickly suppress the fibers pulling the impurities and use inertia to remove the impurities. However, it is much less effective than the blade of the impurity removal knife.

[0084] Accordingly, the plate-shaped component or the rod-shaped component is parallel to the debris removal blade.

[0085] Furthermore, if the shielding component is a plate-shaped component, when the impurity removal area adjustment assembly is in the first stop position, the leading edge of the plate-shaped component is flush with the cutting edge and does not extend forward beyond the vertical plane perpendicular to the front cutting surface of the cutting edge.

[0086] If the shielding component is a rod-shaped component, the vertical projection of the rod-shaped component on the rake face is located inside the rake face, and the leading edge of the projection of the rod-shaped component on the rake face roughly coincides with the leading edge of the rake face.

[0087] like Figure 3 and Figure 11 As shown, the rod-shaped component is preferably a cylindrical rod, or in other words, a round steel component.

[0088] The number of cylindrical bars is two or three, and they are arranged in the extension direction of the second arm of the L-shaped end plate.

[0089] To standardize the process, the following will use... Figure 11 The driving method is illustrated by taking the impurity removal rod assembly 3 as an example. Figure 11 In the middle, the impurity removal rod assembly 3 has two end plates 34, and two or three impurity removal rods 35 are installed between the two end plates 34. The axial direction of the impurity removal rods 35 is parallel to the extension direction of the impurity removal blade.

[0090] The end plate has a bottom hole at 34mm. Due to the thickness of the plate itself, the length of the bottom hole is relatively short. Figure 11 In the structure shown, a mounting sleeve 32 is provided on the inner side of the end plate 34 (the side opposite to the two end plates 34). The mounting sleeve 32 is installed on the end plate 34 by means of welding, for example. The sleeve hole of the mounting sleeve 32 and the bottom hole together form a structure as shown. Figure 11 The mounting hole 31 shown is used for mounting the end plate 34 on the rotating shaft 51.

[0091] Figure 11 In the middle, the mounting sleeve 32 has radial pin holes 33, and if Figure 4 The crank arm assembly 5 shown has a radial pin hole 55 at its end on the shaft 51. The angle of the shaft 51 or the end plate 34 is adjusted to align the pin hole 33 and the pin hole 55, and then a connecting pin is inserted. This connection method can achieve both axial and circumferential connections.

[0092] The above is one form of connection between end plate 34 and rotating shaft 51. It should be noted that there are relatively many structural types in the mechanical field that can achieve both axial and circumferential connections. This is common knowledge in the mechanical field and will not be listed here.

[0093] Therefore, driving the end plate 34 becomes driving the rotating shaft 51. Now let's look at the rotating shaft 51. Figure 4 and Figure 5 In the illustrated structure, the other end of the rotating shaft 51, that is, the end that protrudes from the wall panel 1, is equipped with a drive arm 53 via a key 52. ​​The assembly of the drive arm 53 and the rotating shaft 51 is called the crank arm assembly 5.

[0094] The connection between the drive arm 53 and the rotating shaft 51 in the figure can also be achieved by welding.

[0095] Drive arm 53 in Figure 4 The upper end of the middle has a hinge hole 54, and by means of Figure 6 The triangular mechanism shown in the example is used for driving.

[0096] A triangular mechanism can control both stops entirely without the need for other constraints.

[0097] like Figure 6 In the illustrated structure, the drive arm 53 has a swinging degree of freedom, and a triangular mechanism is formed by using, for example, an electric push rod 7, the drive arm 53, and the frame (wall plate 1). The extension and retraction of the electric push rod 7 must correspond to the swing angle of the drive arm 53 at the two stops, thereby corresponding to the adjustment range of, for example, the impurity removal rod assembly 3.

[0098] Because there are some power machines in the mechanical field that can directly output swing motion, such as swing cylinders and swing motors, they can be directly connected as power machines, for example, rotating shaft 51.

[0099] As mentioned earlier, the triangular mechanism uses a power machine that can directly output linear motion, such as an electric push rod 7. Other common mechanical devices include linear motors, hydraulic cylinders, and pneumatic cylinders. Among them, pneumatic cylinders are difficult to control except for the two dead points, while hydraulic cylinders can achieve relatively precise control.

[0100] In addition, a power machine that produces pure rotational motion can still output oscillation. For example, a servo motor is connected to the rotating shaft 51 through a gear set, and precise oscillation angle control is achieved through servo control.

[0101] In embodiments of the present invention, a linear drive component is preferred. When a linear drive component is used, the pivot 51 constitutes the pivot of a crank arm assembly 5, and the drive arm 53 constitutes a rocker arm based on the mounting of the pivot on the wall panel 1. For example, an electric push rod 7 constitutes the power configuration of a triangular mechanism. In this case, the push rod of the electric push rod 7 can be directly or indirectly hinged to the drive arm 53, and the seat end of the electric push rod 7 also needs to be hinged to the wall panel 1 to form a hinged triangular mechanism.

[0102] The triangular mechanism is a variation of the planar four-bar linkage. For example, the electric push rod 7 is equivalent to two components, specifically the push rod and the cylinder. The two cooperate to form a sliding pair, which is still essentially a hinged four-bar linkage.

[0103] For example, the electric actuator 7 drives the drive arm 53, causing the drive arm 53 to swing 53. Under the condition that the distance between the rotating shaft 51 corresponding to the drive arm 53 and the hinge shaft 13 at the seat end of the electric actuator 7 is determined, the swing range of the drive arm 53 depends on the length of the drive arm 53 and the extension range of the electric actuator 7. Here, for example, the length of the drive arm 53 should be the distance between the axis of the rotating shaft 13 and the axis of the hinge shaft hole 52.

[0104] With the length of the drive arm 53 fixed, the swing range of the drive arm 53 can be adjusted by adjusting the length of the power side rod. Therefore, in a preferred embodiment, for example, the electric push rod 7 is hinged to the drive arm 53 via a length adjustment assembly.

[0105] Furthermore, to meet on-site adjustments, the swing range of the drive arm 53 can be adjusted by limiting, for example, the extension range of the electric push rod 7. Alternatively, the swing range of the drive arm 53 can be adjusted using an intermediate connector. This intermediate connector is the aforementioned length adjustment component.

[0106] exist Figure 6 In the illustrated structure, the length adjustment assembly includes a connecting sleeve 8 and a connecting fish mouth 9, wherein one end of the connecting sleeve 8 is fixedly connected to the push rod of the electric push rod 7, and the other end is connected to one end of the connecting fish mouth 9 shown in the figure by a hinge.

[0107] The other end of the fish mouth 9 is hinged to the drive arm 53 through its fish mouth 92.

[0108] Regarding the location of the connector, it can be on the side connecting the fish mouth 9 or on the side connecting the sleeve 8. Figure 8In the illustrated structure, the left side of the inner hole of the connecting sleeve 8 is a relatively large-diameter sleeve hole 81, and the corresponding sleeve body 83 of the connecting sleeve 8 has a pin hole 82. The right side of the inner hole of the connecting sleeve 8 is a threaded hole 84, and the connecting fish mouth 9 is located there. Figure 9 and Figure 10 The left side of the illustrated structure has a stud 91, which is threadedly connected to the threaded hole 84 to form a threaded pair. The adjustment amount of the threaded pair each time is the length of the stud 91 corresponding to half a turn.

[0109] The push rod end of the electric push rod 7 can be inserted into the sleeve hole 81, and then used... Figure 6 The pin 11 shown is connected with a cotter pin.

[0110] Figure 7 In order to obtain a relatively large assembly space, for example, the seat end of the electric push rod 7 is supported by the bracket 6 at a predetermined height.

[0111] Figure 7 In this context, for example, the fixing sleeve 14 can be a threaded sleeve, one end of which can be fixed to the wall panel 1 by, for example, welding. The bracket 6 can be a plate with fixing holes, used for... Figure 7 The screw 15 mentioned above is used for assembly.
