Description

Technical Field

[0001] This utility model relates to a suction component in a double-pinching roller cotton cleaning machine for sucking away the debris cleaned by the upper pinching roller in conjunction with the upper debris removal knife group. This utility model also relates to a double-pinching roller cotton cleaning machine equipped with the suction component. Background Technology

[0002] In cotton processing, seed cotton undergoes ginning in a ginning machine, achieving a primary separation of cotton fibers from cotton seeds. The resulting collection of separated cotton fibers is called lint, which is typically transferred to the next processing equipment via a conveyor pipe. Due to the prevalence of mechanized harvesting in cotton production, seed cotton often has a relatively high impurity content. Although multiple seed cotton cleaning processes are performed before the ginning station, the final lint still has a high impurity rate. Therefore, the next processing equipment is usually not a baler, but a lint cleaning machine (commonly referred to as a lint cleaner, hereinafter referred to as a lint cleaner) to further clean the lint before baling it.

[0003] Correspondingly, due to the characteristics of machine-picked cotton, the lint obtained after ginning often contains impurities such as cotton leaves, broken cotton stalks, and dead fibers that exceed the predetermined impurity content requirements. To ensure the quality of the lint, these impurities need to be removed using a lint cleaner. In current cotton processing technology, after the lint is output from the ginning machine, it generally undergoes an initial cleaning by an airflow-type lint cleaner, followed by a secondary cleaning by a sawtooth-type lint cleaner before being packaged.

[0004] Currently, commercially available cotton processing production lines are equipped with either one sawtooth cotton cleaning machine or two sawtooth cotton cleaning machines, the latter often referred to as double cleaning. Double cleaning means that the cotton lint first undergoes one cleaning process before entering the second. Essentially, two cleaning machines are set up sequentially on the cotton processing production line. This means that the two cleaning processes do not double the cleaning rate; it remains the same as the single cleaning process. The difference is that the second cleaning process has a relatively higher impurity removal rate.

[0005] Existing cotton processing lines typically have two sawtooth cotton cleaning machines positioned back-to-back, connected by a cotton conveying pipe system equipped with a four-way valve. The need for two cleaning machines increases the production line's footprint and complicates the installation process. Therefore, cleaning machines capable of performing two cleaning stages on a single machine have emerged. A typical example is Chinese patent document CN203144583U, which discloses a double-roller cotton cleaning machine. This machine includes an upper licker-in roller and a set of upper scrap knives cooperating with it, as well as a lower licker-in roller located below the upper licker-in roller and offset forward, along with a set of lower scrap knives cooperating with it. A first scrap discharge port is provided to discharge impurities cleaned by the upper licker-in roller and the upper scrap knives; its structure is a bucket-type structure. The outlet of the No. 1 waste discharge port is located at the bottom of the cotton cleaning machine casing, but its main body is located at the height of the upper licker roller. The No. 1 waste discharge port needs to occupy a relatively large space in the front-to-back direction, and its size is relatively large. In addition, since the upper part of the double-roller cotton cleaning machine is usually a dust cage assembly set in the upper cotton box, it often needs to rely on suction to transfer the cotton from the upper process equipment to the upper licker roller. Although there is a certain sealing capacity between the upper and lower cotton boxes, the lower cotton box will still have a certain negative pressure state, which is not conducive to the discharge of dust and loose debris.

[0006] In view of this, the first discharge port can be connected to an exhaust fan to form a suction and discharge port. Even so, because the first discharge port is typically a bucket-shaped structure with a gradually decreasing cross-sectional area from top to bottom, and the suction and discharge port still needs to extend to the bottom of the lower cotton box, relatively large suction resistance is generated. Furthermore, the suction force decreases relatively quickly as the position increases, and the distribution of the suction airflow lacks rationality. Reference: Chinese Patent Document CN120138816A. Utility Model Content

[0007] The purpose of this invention is to provide a suction component with relatively good suction effect, and to provide a double-roller cotton cleaning machine equipped with the suction component.

[0008] According to a first aspect of the present invention, a debris suction assembly is provided for suctioning away debris cleaned by the upper licker-in roller in conjunction with the upper debris removal knife group in a double-licker-in roller cotton cleaning machine. The debris suction assembly includes: The receiving base plate is horizontally placed in the lower cotton box of the double-pinning roller cotton cleaning machine and located on one side below the upper pinning roller. This side is where the upper row of impurity knives is located, and the receiving base plate is a tubular base plate with an open side facing the upper pinning roller. One end of the receiving base plate has a flange for connecting to the impurity suction pipe, and the open side forms an impurity receiving port. The slide plate continues to the lower edge of the miscellaneous outlet and extends to the first miscellaneous knife in the lowermost row of the upper row of miscellaneous knife groups; A wind deflector is used to partially cover the inlet of the inlet and to partially cover the outlet of the inlet in the adjustment direction defined by the upper and lower edges of the inlet; correspondingly, the wind deflector is engaged with the upper edge of the inlet of the inlet. Accordingly, the wind deflector is adapted with an adjustment structure or adjustment mechanism for adjusting the wind deflector in the adjustment direction.

[0009] Optionally, a first side plate is provided, which is connected to the upper edge and extends in the adjustment direction away from the lower edge; Accordingly, the wind deflector is attached to the first side plate.

[0010] Optionally, the adjustment structure is adapted to be a guide pair, and the guiding direction of the guide pair is the adjustment direction; Accordingly, a locking element adapted to the guide pair is provided for locking after the wind deflector has been adjusted.

[0011] Optionally, the guiding pair has: In the first configuration, the windbreak plate has first end plates at both ends. One of the first end plates and the wall panel of the corresponding lower cotton box has a first elongated hole, and the other has a first fixing hole. Bolts passing through the first elongated hole and the first fixing hole and guided into the first elongated hole are provided to form a guide pair; or In the second configuration, one of the windshield and the first side plate is provided with a second elongated hole, and the other is provided with a second fixing hole, providing bolts that pass through the second elongated hole and the second fixing hole and are guided in the second elongated hole to form a guide pair; or The third structure includes a linear guide rail or guide rod on the first side plate or corresponding wall plate, and a corresponding slider or guide sleeve on the wind deflector plate to form a guide pair; The adjustment directions are defined as follows: the extension direction of the first elongated hole, the extension direction of the second elongated hole, the extension direction of the linear guide rail, and the rod direction of the guide rod.

[0012] Optionally, the end of the first side plate is directly or indirectly fixed to the corresponding cover plate of the lower cotton box.

[0013] Optionally, the first side plate, the receiving bottom plate, and the slide plate are formed by bending a single sheet material, referred to as a bent part.

[0014] Optionally, the connection between the bent component and the corresponding wall panel has connection points at the first side plate, the bottom plate, and the slide plate.

[0015] Optionally, the slide is fixedly connected to the first upper row of miscellaneous blades or joined by a sealing rubber sheet.

[0016] Optionally, the receiving base plate is a circular tube or a rectangular tube. If it is a circular tube, the central angle corresponding to the circular tube portion determined by the upper and lower edges is 120°~160°. If it is a rectangular tube, the panel facing the upward-facing roller will be used to form the interface.

[0017] Optionally, the lower edge of the wind deflector is an upward-curving or V-shaped arc.

[0018] According to a second aspect of the present invention, a double-pinched roller cotton cleaning machine is provided, including the impurity suction component described in the first aspect of the present invention, wherein the lower edge of the impurity receiving base plate is not lower than the upper cover plate of the cotton channel of the cotton channel provided by the double-pinched roller cotton cleaning machine.

[0019] It should be understood that the basic principle of a double-roller cotton cleaning machine is based on the fact that impurities mixed in with the cotton, such as cotton stalks, have a higher specific gravity than the loose cotton. After the cotton is captured by the upper roller, it rotates with the upper roller. Substances with different specific gravities are affected differently by centrifugal force, causing the impurities to move outward. In addition to impurities that are directly thrown away, some impurities are pulled by the cotton fibers. Then, under the action of the impurity discharge knife, the impurities fly out along the front blade of the discharge knife. The flying impurities directly impact the chute or fall onto the chute after being countered by the lower cotton box cover plate. In other words, most of the impurities will slide down the wall of the discharge hopper or bounce down.

[0020] Accordingly, in the embodiments of this utility model, the provided tubular bottom plate for receiving impurities is horizontally placed in the lower cotton box of the double-pinching roller cotton cleaning machine, and located on one side below the upper pinching roller, with the side facing the upper pinching roller being the open side. A chute is further provided, which continues from the lower edge of the receiving port and extends to the first upper row of impurity knives in the upper row of impurity knives for guiding material. A baffle plate is also provided for partially shielding the receiving port, and this baffle plate always remains engaged with the upper edge. In other words, an air intake is defined between the baffle plate and the lower edge. Since the flow cross-sectional area of ​​the air intake is reduced compared to a simple receiving port, the suction force is relatively increased at the same suction rate, and the main body of the suction airflow is biased towards the side where the chute is located, which is beneficial for the rapid collection and discharge of impurities.

[0029] To facilitate understanding of this utility model, a more detailed description of it is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of this utility model focus on describing how to quickly gather debris and discharge it through the first debris discharge channel 29; however, other parts of the cotton cleaning machine can utilize existing technologies.

[0030] It should be understood that cotton processing equipment typically has defined front-back and left-right directions. For a cotton cleaning machine, the two sides of the cotton flow direction define the machine's spokes, each with a corresponding width. The left and right directions are also referred to as the transverse or width directions. For a cotton cleaning machine, the left and right sides of the machine casing are constructed from relatively thick plates, such as steel plates, to form the wall panels 16. These wall panels 16 serve as the main mounting base for the components inside the casing, with most components mounted directly or indirectly on them.

[0031] In the front-back direction and above, the components used to enclose the cavity of the combined wall panel 16 are generally not load-bearing and are usually made of sheet metal, and are often referred to as cover panels.

[0032] Correspondingly, the longitudinal direction is determined by the front-to-back direction, which is also called the longitudinal direction, the head-to-tail direction, etc.

[0033] In the embodiments of this utility model, there are definite up and down positions. However, it should be understood that in the mechanical field, up and down does not specifically refer to being directly above or below, but usually indicates a height difference. For example, the upper licking roller 9 is not necessarily located directly above the lower licking roller 17; they are a pair of relative concepts with a height difference in positional relationship. Furthermore, in the embodiments of this utility model, "up," "down," and other terms such as left, right, inside, outside, front, and back, as well as similar expressions, are for illustrative and explanatory purposes only, and are limited to not causing misunderstanding to those skilled in the art.

[0034] Similarly, statements that are mutually explanatory, such as vertical or horizontal, are also for the purpose of explanation or clarification.

[0035] In addition, to facilitate the description of the relationship between one component or component and another component or component shown in the accompanying drawings, spatially relative terms such as "lower," "upper," and similar terms may be used in embodiments of this invention. It should be understood that the spatially relative terms are intended to cover different orientations of the device during use and operation, in addition to those depicted in the accompanying drawings.

[0036] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0037] Furthermore, as a special note, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] It should be understood that in the field of mechanics, standard geometric terms are typically used to describe approximate mechanical structures, without implying that the mechanical mechanism possesses the geometric characteristics corresponding to those terms in a strict sense. For example, the curved plate commonly referred to in the field of mechanics is actually a partially cylindrical plate. In the field of mechanics, a certain explicit feature is usually used to determine the terminology, which does not mean that its structure or construction is completely constrained by the corresponding geometric concept.

[0039] First, based on the basic concept of this utility model, the wind deflector 36 is used to cover part of the debris inlet to increase the suction force in the local area, thereby quickly collecting debris.

[0040] Upper licker roller 9 and lower licker roller 17 in Figure 1In the illustrated structure, all are installed inside the lower casing 25, while the upper cotton box of the cotton cleaning machine is generally equipped with a cotton inlet pipe and a dust cage assembly.

[0041] The dust cage assembly includes a dust cage, which is mounted on the upper wall panel via a bearing assembly. One or both ends of the dust cage are connected to an air extraction port, which generates cotton conveying power through the cotton inlet pipe by air extraction, and causes the cotton entering the cotton cleaning machine through the cotton inlet pipe to be adsorbed onto the dust cage mesh surface, which is similar to cotton suction. At the same time, it will also create a negative pressure state inside the upper cotton box.

[0042] The lower cotton box, which connects to the upper cotton box vertically, is like... Figure 1 The structure shown depicts a connection between the upper and lower cotton boxes. Generally, a dust cage sealing assembly is required to seal the space between the upper and lower cotton boxes at a predetermined location, typically in conjunction with the pressing roller 11 or the stripping roller 12. Although the lower cotton box is affected by the negative pressure of the upper cotton box, the impurities discharged by the waste removal knife are mostly heavy impurities in the sense of lint cleaning, and the impact is relatively small. However, if the waste suction airflow is inadequate, it will affect the rapid collection and discharge of impurities.

[0043] As mentioned earlier, after the cotton lint enters the upper casing, some light impurities are discharged through the exhaust fan of the dust cage assembly during the process of being adsorbed onto the mesh surface of the dust cage. The dust cage mesh surface is generally a cylindrical perforated plate with a flat surface, suitable for being peeled off by the peeling roller 12. The peeled cotton lint is conveyed downwards under the clamping of the peeling roller 12 and the pressing roller 11. Therefore, it can be seen that... Figure 1 In the illustrated state, the upper licker roller 9 rotates counterclockwise. The shed cotton is pressed by the pressing roller 11 and captured by the upper licker roller 9, and rotates with the upper licker roller 9.

[0044] Figure 1 In the diagram, the first row of debris knife group 7, also known as the upper row of debris knife group, is located to the left of the upper licker roller 9, which is the front side of the cotton cleaning machine. The debris cleaned by the first row of debris knife group 7 will fly out along the front blade surface of the debris knife and hit, for example, the front cover plate 8 or the debris suction component 4 (the angle between the front blade surface of the debris knife and the horizontal plane is different in different positions), and then move downward under the action of gravity.

[0045] When the cotton loses the radial restraint of the other components except for the upper licker-in roller 9, the cotton layer on the upper licker-in roller 9 tends to become radially fluffy under the action of centrifugal force, causing the relatively heavy impurities to move towards the centrifugal side of the cotton layer. In addition to the impurities that fly out directly due to the centrifugal force, some impurities are pulled by the cotton fibers and are in a state of being pulled by the cotton fibers and thus flying along.

[0046] Figure 1The first row of miscellaneous blades, arranged in an arc on the left side, is designated as the first row of miscellaneous blades group 7. When the cotton fibers pulling the miscellaneous material are blocked by the first row of miscellaneous blades, the speed of the miscellaneous material changes drastically, causing the miscellaneous material to detach from the cotton fibers and be separated, and then... Figure 1 The suction component 4 shown is used to remove the debris cleaned by the upper suction roller 9 in conjunction with the upper debris removal knife group in the double-pinching roller cotton cleaning machine.

[0047] The impurity collection component 4 uses an impurity receiving bottom plate 27 for final material collection. The impurity receiving bottom plate 27 is located in... Figure 1 As can be seen in the illustrated structure, its position is roughly in the middle of the lower cotton box 25 in the vertical direction, rather than at the bottom of the lower cotton box 25. The flow distance of the debris before it is sucked away is greatly shortened, which can reduce the suction power attenuation.

[0048] Furthermore, from Figure 1 As can be seen, the output channel used for cleaning the lint is, for example, Figure 1 The cotton outlet channel 2 is defined by the upper cover plate 3 and the lower cover plate 1 of the cotton channel. If the upper cover plate 3 of the cotton channel has sufficient rigidity, the suction component 4 can be directly supported on the upper cover plate 3 of the cotton channel. Even if the upper cover plate 3 of the cotton channel is not rigid enough to support the suction component 4, both ends of the suction component 4 can be fixed on the wall plate 16. The upper cover plate 3 of the cotton channel can play the role of auxiliary support for the suction component 4.

[0049] Furthermore, in a more preferred embodiment, the receiving base plate 27 in the impurity suction assembly 4 is joined with the upper cover plate 3 of the cotton channel to fully stretch the combing space of the impurities discharged by the upper impurity discharge knife assembly, and based on gravity and the flight trajectory of the impurities, the impurity suction airflow can more easily act on most of the impurities, thus making more effective use of the impurity suction airflow.

[0050] Furthermore, the internal unused space of the lower cotton box 25 is usually quite large, such as... Figure 1 The space of the lower cotton box 25 located above the upper cover plate 3 of the cotton channel is sufficient to accommodate the suction component 4. In other words, the suction component 4 based on the present invention will not occupy additional functional space, thus making the overall structure relatively compact.

[0051] The receiving base plate 27 is a partially split pipe structure. The receiving base plate 27 is placed horizontally inside the lower cotton box 25 of the double-pinched roller cotton cleaning machine, and as can be seen from the above description, it is roughly located in the middle of the lower cotton box 25 in the vertical direction.

[0052] based on Figure 1The first row of debris-removing blades 7 shown in the diagram is positioned such that the separated debris is thrown out in a roughly oblique manner. Although the initial angle of the oblique throw is different, the debris must fall due to the counterattack from the cover plate and the force of gravity. In this embodiment of the invention, the airflow is organized by the cooperation of the debris-removing bottom 27 and the wind deflector 36, thereby making the airflow in some areas relatively large.

[0053] Since the receiving plate 27 is located on the side below the upper licker-in roller 9, and the open side of the receiving plate 27 is the side where the upper licker-in roller 9 of the cotton box is located, the positional relationship determines that the plane of the receiving port formed by its open side, measured from the upper and lower edges, is a plane that forms a first angle with the horizontal plane.

[0054] Since the wind deflector 36 is used to partially shield the inlet, and the angle between the wind deflector 36 and the horizontal plane is the same as the first angle, the wind deflector 36 is also an inclined plate, which can also form a slope panel suitable for debris to roll off.

[0055] Accordingly, one end of the tubular base plate 27 is used to connect to the air duct, which is the suction pipe. Since suction itself is common knowledge in the field and is not related to the part improved by this utility model, this utility model focuses on how to manage the suction airflow, so the suction pipe and the like will not be described in detail here.

[0056] As mentioned earlier, the wind deflector 36 is an angled plate, and based on the location of the inlet, it is... Figures 1-3 In the illustrated structure, it is clear that the structure gradually slopes backward as it extends downward, forming the first sloping panel. Correspondingly, a slide 5 is provided, which... Figure 1 The illustrated structure is characterized by a gradual forward inclination as it extends downwards, thus forming a second sloping panel. The two sloping panels together form a bucket-shaped material collection structure.

[0057] Correspondingly, the slide plate 5 continues to the lower edge of the miscellaneous outlet and extends to the first upper row miscellaneous knife in the upper row miscellaneous knife group, forming the second slope panel, and more preferably, it is closed at the upper end of the first row miscellaneous knife group 7 knife holder.

[0058] from Figure 1 As can be seen, the bottom plate 27 is basically in a state of near-limit front positioning, and its interface is... Figures 1-3 The opening is slanted, with the front higher than the back. The slant direction of the corresponding baffle 36 is consistent with the slant direction of the receiving port. Therefore, when the baffle 36 can move in the slanted direction, its shielding amount of the receiving port will change. This change is reflected in the change of the opening size of the receiving port, and thus in the change of the suction force of the suction component 4. The opening part extends from the lower edge of the receiving port to the lower edge of the baffle 36, and the suction airflow is directed to the lower part of the receiving port.

[0059] Correspondingly, since more debris will descend along the slide 5, and the slide 5 continues to the lower edge of the debris inlet to form a second sloping panel, the combed airflow can more easily collect and discharge the debris in a timely manner.

[0060] Therefore, the wind deflector 36 partially covers the inlet from front to back. In other words, during the adjustment process, the wind deflector 36 is required to partially cover the inlet and partially cover the outlet in the adjustment direction determined by the upper and lower edges of the inlet, so as to adjust the size of the opening part according to the working conditions.

[0061] from Figure 1 As can be seen, both the front cover 8 and the rear cover 20 of the lower cotton box 25 have inspection ports, such as... Figure 1 Even though the part of the front access port 10 shown is an adjustment structure for adjusting the windshield 36, it can still be adjusted by opening the front access port 10.

[0062] In some implementations, such as Figure 2 As shown, the structure for mounting the baffle 36 on the wall panel 16 is the first elongated hole 34 shown in the figure, which allows the baffle 36 to be adjusted in the direction of the inlet tilt without opening, for example, the front access port 10. In contrast, the first elongated hole 34 is located on the first end plate 33, and generally requires access to the upper housing 25 via, for example, the front access port 10, to assist in the adjustment of the baffle 36. If the elongated hole is located on the wall panel 16, the baffle 36 can be adjusted without opening the front access port 10 at all.

[0063] In some implementations, an adjustment mechanism can be used to adjust the wind deflector 36, such as a lead screw mechanism. The lead screw of the lead screw mechanism is connected to the wind deflector 36, and the lead screw nut acts as the driving element. The position of the wind deflector 36 is adjusted by controlling the rotation of the lead screw nut.

[0064] Due to the harsh working conditions in the waste discharge space, the lead screw can be covered by, for example, a bellows. One end of the bellows is fixed to the wind baffle 36, and the other end is fixed to the frame where the lead screw nut is located. Obviously, the axis of the bellows and the axis of the lead screw need to maintain relatively good coaxiality.

[0065] In a preferred embodiment, a first side plate 32 is provided, which is connected to the upper edge and extends in the adjustment direction away from the lower edge, thereby presenting a shape as shown in the figure. Figure 2 and Figure 3The state shown is as follows. The main purpose of setting the first side plate 32 is to ensure the relative enclosure of the first waste discharge channel 23 relative to the surrounding environment under the condition that the wind baffle 36 needs to be adjusted, that is, its position needs to change. Under this condition, it is necessary to ensure that the space above the first waste discharge channel 29 is relatively sealed while satisfying the adjustment of the wind baffle 36. At this time, it is necessary to configure components such as accordion covers or other components that can still meet the sealing requirements when the wind baffle is adjusted. The overall structure will be relatively complex. In addition, for example, accordion covers are prone to embedding debris on their surface and are not easy to clean.

[0066] Meanwhile, since the wind deflector 36 needs to be engaged with the upper edge, the upper edge can be provided with, for example, a flange to increase its support area for the wind deflector 36, but this method will still face the aforementioned sealing problem.

[0067] Combination Figure 1 and Figure 2 As can be seen from the illustrated structure, the first side plate 32 extends to the front cover plate 8. Since it is a statically determinate structure, it is easy to form a static seal and it is not easy for debris to get embedded. At the same time, it can obviously provide good support and guidance for the wind deflector 36.

[0068] Correspondingly, Figures 1-3 The slide plate 5 shown can form a second side plate. The second side plate, the impurity receiving base plate 27, and the first side plate 32 constitute the main body of the impurity suction assembly. The main body can be formed as a whole from a rectangular sheet metal block by, for example, a bending forming process.

[0069] Therefore, with the first side plate 32 in place, on the one hand, the first side plate 32 can be combined with, for example, the front cover plate 8 to achieve connection and sealing on that side; on the other hand, the wind deflector 36 can be attached to the first side plate 32, so that the first side plate 32 provides certain support and guidance for the wind deflector 36, which helps to adjust the wind deflector 36 and maintain its adjusted posture.

[0070] Regarding the structural configuration for adjustment, if an adjustment structure is adopted, it is adapted as a guide pair. The guide pair ensures relative accuracy of the adjustment through its guidance. Correspondingly, the guiding direction of this guide pair is the adjustment direction.

[0071] Furthermore, a locking element adapted to the guide pair is provided for locking after the wind deflector 36 has been adjusted, thereby ensuring that the adjusted wind deflector 36 maintains its posture.

[0072] Regarding the selection of the guide pair, it can be selected from the following three structures, or other similar structures can be selected based on these three basic structures.

[0073] Firstly, in the first structure, the wind deflector 36 has a first end plate 33 at both ends, and the first end plate 33 is located at... Figure 1 and Figure 5 The illustrated structure has two first elongated holes 34, while Figure 6 In the illustrated structure, the first end plate 33 is provided with a fourth threaded hole 48. Correspondingly, if the first end plate 33 is provided with a first elongated hole 34, the wall plate 16 is provided with a first fixing hole. When the first elongated hole 34 is provided on the wall plate 16, the fourth threaded hole 48 that constitutes the first fixing hole is provided on the first end plate 33. By means of the correspondence between the first elongated hole 34 and the first fixing hole, a bolt is passed through to form a guide pair. In other words, the bolt can be loosened first, but not detached, and then adjusted. After the adjustment is completed, the bolt can be locked.

[0074] Then there is the second configuration, in which one of the wind deflector 36 and the first side plate 32 is provided with a second elongated hole, and the other is provided with a second fixing hole. Compared with the first configuration, the first side plate 32 replaces the wall plate 16. This type of adjustment requires opening the front access port 10 for adjustment. Correspondingly, bolts that pass through the second elongated hole and the second fixing hole and are guided in the second elongated hole are provided to form a guide pair.

[0075] Furthermore, since the wind deflector 36 needs to bear wind pressure, although the first side plate 32 in the first structure also needs to bear pressure, the wall plate 16 bears relatively large pressure, making it less likely for the first side plate 32 and the connecting bottom plate 27 to deform.

[0076] The third structure involves a linear guide rail or guide rod on the first side plate 32 or the corresponding wall plate 16, and a slider or guide sleeve on the wind baffle 36 to form a guide pair. Locking the slider is relatively simple; for example, a set screw can be used. After adjustment, the set screw is held in place on the linear guide rail or guide rod through the set screw hole on the slider or guide sleeve to form a lock.

[0077] The adjustment directions are defined as follows: the extension direction of the first elongated hole 34, the extension direction of the second elongated hole, the extension direction of the linear guide rail, and the rod direction of the guide rod.

[0078] exist Figure 5 As can be seen in the illustrated structure, there are two first elongated holes 34, which are staggered in a direction parallel to the wind deflector 36. This helps to form a relatively reliable fixation when the number of first elongated holes 34 is relatively small.

[0079] As mentioned earlier, the first side plate 32, the receiving bottom plate 27, and the slide plate 5 are integrally formed from a single sheet material. In particular, the receiving bottom plate 27 needs to be wound into, for example... Figure 2The partially cut-out cylindrical structure shown in the figure is thus called a bent part when the three parts are formed together as a whole.

[0080] Obviously, the first side plate 32 and the receiving base plate 27 are bent at the upper edge. For the slide plate 5, it can be tangent to the receiving base plate 27 at the lower edge, or it can intersect. When intersecting, the central angle of the corresponding chord is no greater than 90°. The main considerations for the intersection are the size setting of the receiving port and the tilt angle of the slide plate 5.

[0081] To improve overall assembly stability, the connection between the bent component and the corresponding wall panel 16 has connection points at the first side plate 32, the receiving bottom plate 27, and the slide plate 5. Figure 3 As can be seen in the figure, the flange 26 is an integrally constructed flange at the junction of the base plate 27 and the first side plate 32. The portion located at the first side plate 32 has a second threaded hole 38, and the portion located at the junction of the base plate 27 has a first threaded hole 28. Simultaneously, the ends of a portion of the slide plate 5 are provided with... Figure 3 The second end plate 47 shown in the figure has a third threaded hole 46, which allows the bent part to be fixed to the wall panel 16 relatively reliably by means of the first threaded hole 28, the second threaded hole 38 and the third threaded hole 46.

[0082] Regarding other auxiliary settings, the main one is the sealing method between the upper end of the slide 5 and the first upper row of miscellaneous blades. One method is a fixed connection, and the other is a joint through the sealing rubber 43. The fixed connection structure has relatively better reliability and is also simpler in structure, while the joint using the sealing rubber 43 can effectively reduce vibration.

[0083] Regarding the structural form of the receiving base plate 27, a round tube is preferred. When using a round tube, the central angle corresponding to the round tube portion determined by the upper and lower edges is 120°~160°. This central angle should not be too small, otherwise the suction force will be relatively dispersed. It should also not be too large, otherwise the receiving port will be too small, affecting the material collection.

[0084] Alternatively, the receiving base plate 27 can also be a rectangular tube. If a rectangular hole is used, the panel facing the upward-facing piercing roller 9 is left untouched and forms the receiving port.

[0085] Figure 7 The diagram shows the main view of the wind deflector 36. The left and right sides in the diagram correspond to the left and right sides of the lower cotton box 25. That is, in the horizontal direction, the lower edge of the wind deflector 36 is an upward bow or V-shape, which can more effectively organize the airflow and collect and suck away debris.

[0086] When using a V-shape, the V-angle of the V-shape should not be too large, otherwise it will have too much impact on the wind-blocking effect. Therefore, the V-angle is around 173°, with 173° being the preferred value. When using an arc shape, the top of the arc shape should refer to the top of the V-shape.
