Description

Technical Field

[0001] This invention relates to a double-layer sawtooth stripping machine. Background Technology

[0002] A delinting machine is a type of cotton processing equipment. Its basic function is to remove the cotton fibers remaining on the cotton seeds after ginning. Compared to the lint separated by a ginning machine, the cotton fibers removed from the cotton seeds are shorter and are usually called short fibers. A typical characteristic of short fibers is that their specific surface area is larger than that of the lint separated by a ginning machine, making them easier to separate using airflow. The component used to provide airflow in a delinting machine is called a nozzle. The width of the nozzle at the delinting component is roughly equivalent to the width of the delinting machine's spokes, and it blocks the delinting component from below in a vertical direction.

[0003] Note: The sawtooth stripping machine conforms to the national standard GB / T 21306-2007 "Sawtooth Stripping Machine" and is currently the most widely used stripping machine.

[0004] Currently, saw-tooth stripping machines on the market are mainly classified into two types according to their assembly structure: single-layer saw-tooth stripping machines and double-layer saw-tooth stripping machines. Double-layer saw-tooth stripping machines have two stripping assemblies, which are connected vertically and are divided into upper and lower layers. The upper stripping assembly mainly strips the second layer of down, while the lower stripping assembly mainly strips the third layer of down.

[0005] Typically, Chinese patent document CN101781798A discloses a composite airflow sawtooth stripping machine, which is essentially a double-layer sawtooth stripping machine. It includes a mounting base, a first-layer stripping and stripping mechanism, and a second-layer stripping and stripping mechanism. The first-layer stripping and stripping mechanism is located in the middle of the mounting base, while the second-layer stripping and stripping mechanism is located in the lower part of the mounting base and below the first-layer stripping and stripping mechanism. The first and second layer stripping and picking mechanisms have the same structure, both including at least a box cover, a seed-dispensing section, a stripping section, a picking device, a push rod mechanism, and a debris removal device. The inlet of the seed-dispensing section is connected to the outlet of the self-controlled seed feeding device via a front-flowing seed plate. The stripping section is located below the seed-dispensing section, and the debris removal device is located behind the inlet of the picking device. The picking device is a pneumatic suction type and includes a suction tube. The opening of the suction tube needs to be roughly equivalent to the machine's radius to remove the short fibers stripped by the stripping machine within the machine's radius. Under these conditions, to avoid being blocked by the suction tube, the debris removal device needs to be located above the suction tube. Simultaneously, due to the obstruction of the suction tube, impurities separated by the first layer stripping and picking mechanism will not fall into the second layer. Therefore, both stripping and picking mechanisms require debris removal devices.

[0006] It should be noted that, on the cotton processing production line, before delinting, seed cotton cleaning and lint cleaning are carried out at least once, and most impurities have been removed. The impurities mixed into the seed cotton are often heavy impurities with a relatively large proportion. At this time, the impurity content in the cottonseed is relatively low. Equipping two sets of impurity removal devices is not only costly, but also, in terms of impurity removal capacity, the configuration of impurity removal devices is usually too redundant, which will result in unnecessary waste.

[0007] In addition, the two sets of air nozzles and two sets of impurity removal devices need to be arranged in the vertical direction, which will make the overall height of the double-layer sawtooth delinting machine relatively high. Furthermore, due to the large number of components and the complex overall structure, the equipment failure rate will also be relatively high. Summary of the Invention

[0008] The purpose of this invention is to provide a relatively compact double-layer sawtooth delinting machine.

[0009] According to an embodiment of the present invention, a double-layer sawtooth delinting machine is provided, comprising:

[0010] The upper working box has an upper outlet at the bottom;

[0011] Upper rib, located on the lower rear side of the upper outlet;

[0012] The upper saw cylinder, in conjunction with the upper rib, forms the upper stripping section;

[0013] The upper debris removal component includes a first part located on the rear side of the upper saw cylinder;

[0014] The upper lint suction section is located on the upper rear side of the first part or on the upper side of the part of the first part that mates with the upper saw cylinder, so as to suck away the short lint stripped off by the upper lint stripping section;

[0015] The lower working box, located below the upper working box, receives the cotton seeds guided down by the upper ribs, and has a lower outlet at the bottom.

[0016] Lower rib, located behind the lower outlet;

[0017] The lower saw cylinder, in conjunction with the lower rib, forms the lower stripping section;

[0018] The third row of miscellaneous blades is located behind the lower saw cylinder; the wedge-shaped space between the third row of miscellaneous blades and the lower saw cylinder forms a lint-absorbing area.

[0019] The impurity removal assembly is located below and behind the third row of impurity cutters to receive impurities discharged by the third row of impurity cutters and to receive impurities discharged by the upper impurity removal component; and

[0020] The air nozzle receives the down-absorbing area to suck away the short fibers peeled off from the lower down-absorbing section.

[0021] Optionally, the upper debris removal component further includes a brush, which is a roller brush with its axis parallel to the axis of the upper saw cylinder and cooperates with the upper rear side of the upper saw cylinder to brush off the short fibers on the upper saw cylinder.

[0022] The inlet of the upper absorbent part is located on the rear side of the brush;

[0023] Accordingly, a first row of debris removal blades, which are included in the upper debris removal component, is provided between the brush and the inlet of the upper suction part to remove heavy debris from the brush.

[0024] Optionally, the first row of miscellaneous blades and the mounting plate of the first row of miscellaneous blades form the front sidewall of the upper suction part inlet, and a rear suction plate forming the rear sidewall is provided on the rear side of the front sidewall.

[0025] Optionally, an arc-shaped plate is connected to the lower end of the rear feed chute to collect material downwards and forwards;

[0026] The end of the curved plate is connected to a downward and backward extending miscellaneous plate;

[0027] The first part includes a second row of scrap blades that cooperate with the upper saw cylinder, and a first baffle plate located in front of the scrap plate; the first baffle plate and the scrap plate form a downward channel for impurities; the upper end of the first baffle plate is engaged with the second row of scrap blades.

[0028] Optionally, the waste removal assembly is located in the middle of the double-layer sawtooth delinting machine in the front-to-back direction;

[0029] The discharge assembly inlet has a discharge plate that forms a receiving hopper; the discharge plate extends upward and backward from the upper edge of the inlet.

[0030] Optionally, a second baffle plate is provided on the side above the impurity discharge assembly opposite to the impurity flow plate, so as to guide the impurities discharged above to the impurity flow plate or the impurity discharge assembly.

[0031] Optionally, the waste removal assembly is called a waste removal auger.

[0032] Optionally, a feeding section is provided at the inlet of the upper working box.

[0033] Optionally, the feeding section includes:

[0034] The enclosure is configured as a top-in, bottom-out enclosure;

[0035] Feed rollers are a pair of feed roller shafts located at the inlet of the housing;

[0036] The magnetic plate is located below the feed roller and extends forward and downward from the rear wall of the housing.

[0037] The inspection door is located on the front side of the enclosure and is aligned with the magnetic plate.

[0038] Optionally, a material guide plate extending backward and downward from the front wall of the box is provided on the lower side of the inspection door inside the box.

[0039] The double-layer sawtooth defrosting machine according to an embodiment of the present invention replaces the traditional upper air nozzle with an upper suction part. The difference is that the upper suction part is located above the upper impurity removal component. Regardless of its position on the upper side, it will not obstruct the falling of impurities. Therefore, with two sets of defrosting assemblies, only one impurity removal assembly is required, thereby reducing the overall complexity and height of the double-layer sawtooth defrosting machine and making the overall design more compact. At the same time, with reduced system complexity, its reliability is also relatively better. Attached Figure Description

[0046] It should be understood that, for a delinting machine, the side where the feed inlet is located is the front side, and the side opposite the front side is the rear side, which has a definite orientation in this field.

[0047] The front and back directions determine the longitudinal direction. In the reference plane, the direction perpendicular to the front and back direction is the left and right direction, also known as the transverse or width direction. The machine spokes are thus determined. The machine spokes can be simply understood as the width of the working part of the machine.

[0048] In an embodiment of the present invention, the first improvement is to save one set of impurity removal assembly, making the whole machine relatively compact while preventing the impurity removal assembly from being too redundant. As mentioned above, the impurity content of cottonseed is already very low compared to seed cotton, and it is mainly heavy impurities, so configuring two sets of impurity removal assemblies would be too redundant.

[0049] In an embodiment of the present invention, a second improvement is achieved by using a brush 14 to assist in the absorption of down.

[0050] In an embodiment of the present invention, the third improvement is how the cooperation relationship between the brush 14 and the upper saw cylinder 8 is configured when the brush 14 is used, and how the specific structure or construction of the suction brush is configured.

[0051] In an embodiment of the present invention, in order to avoid damage to the saw barrel, the fourth improvement of the double-layer saw tooth stripping machine is that a feeding section 12 is provided at the inlet of the machine. The feeding section 12 is equipped with a magnetic plate 31, which is used to adsorb some ferromagnetic impurities, and then the magnetic plate 31 is cleaned regularly.

[0052] The remaining parts can directly adopt the inherent configuration in the existing technology. These other parts will not be described in detail below, such as the working box, the cooperation between the working box and the saw barrel, and the cooperation between the saw barrel and the debris removal knife, all of which belong to the existing technology.

[0053] Figure 1 In the middle, the position of the third row of miscellaneous blades 26, as well as its configuration with the lower saw cylinder 3 and the connection position of the air nozzle 25, are common configurations. At this time, the lower saw cylinder 3 rotates clockwise. The short fibers hooked by the saw blade teeth on the lower saw cylinder 3 and the impurities wrapped around the short fibers first come into contact with the third row of miscellaneous blades 26. Due to the influence of centrifugal force, the impurities have a relatively large specific gravity and are located on the outside. When the short fibers wrapped with impurities collide with the third row of miscellaneous blades 26, due to the influence of inertia, the impurities separate from the short fibers. A very small amount of short fibers wrapped with impurities may also be cut off and enter, for example, the impurity discharge auger 27 along with the impurities.

[0054] Then, the short fibers cleaned by the third row of miscellaneous blades 26 enter the wedge-shaped area between the third row of miscellaneous blades 26 and the lower saw cylinder 3. This wedge-shaped area is called the fiber suction area 39. The mouth of the air nozzle 25 covers the fiber suction area 39, and the short fibers hooked on the saw teeth of the lower saw cylinder 3 are sucked away by the air force.

[0055] It should be understood that traditional double-layer sawtooth delinting machines are equipped with two sets of air nozzles 25, and a corresponding configuration similar to that at the aforementioned third row of debris cutters 26. Since the air nozzles 25 are located below, for example, the debris removal auger 27, if two sets of air nozzles 25 are provided, the upper air nozzle 25 will inevitably block the downward passage of debris, thus requiring a separate debris removal assembly for the upper debris.

[0056] Furthermore, in the embodiments of the present invention, after long-term research, it was found that some of the short fibers hooked by the upper saw cylinder 8 will be entangled with impurities. In other words, some will not be entangled with impurities, and the short fibers that are not entangled with impurities have a higher specific gravity. Under the condition of directly sucking up fibers without cleaning, most of the short fibers can be sucked up.

[0057] At the same time, after cleaning, the short fibers entangled with impurities will not detach from the saw blade teeth of the upper saw cylinder 8 and will continue to rotate until they are sucked away. In other words, even without a configuration like... Figure 1 The brush 14 shown can still have an upper suction part configured on the upper side or upper rear side where the upper saw cylinder 8 meets, for example, the second row of miscellaneous blades 20 in the figure.

[0058] Preferably, the brush 14 is used as a medium to transfer most of the short fibers onto the brush 14, and then the upper suction part is used to suck away the short fibers on the brush 14.

[0059] Furthermore, as a further preferred option, the upper lint suction section is also equipped with, for example, a first row of debris cutters 17, to further clean the short lint with impurities that has been transferred to the brush 14, thereby improving the lint recovery rate.

[0060] Combination Figure 1 As can be seen from the example where the first row of miscellaneous blades 17 and the second row of miscellaneous blades 20 are configured simultaneously, the brush 14 cannot transfer all the short fibers wrapped around the upper saw cylinder 8. In other words, some short fibers will always be rotated along with the upper saw cylinder 8. Thus, it can be confirmed that even without the brush 14, it is still feasible to directly suck up the fibers from the upper saw cylinder 8, although the effect is slightly worse than the example with the brush 14.

[0061] The basic structure of the double-layer sawtooth delinting machine in the embodiments of the present invention is described below in conjunction with the above content. Figure 1 In the illustrated structure, the double-layer saw-tooth stripping machine includes an upper working box 11, an upper rib 9, and an upper saw cylinder 8, thereby defining the upper layer; Figure 1 The illustrated structure further includes a lower working box 5, a lower saw cylinder 3, and a lower rib 2, thereby defining the lower layer.

[0062] First, let's look at the feeding method. The upper working box 11 has an inlet for introducing cotton seeds, and the upper working box 11 is equipped with an upper seed-feeding roller for uniform feeding.

[0063] like Figure 4The way the working box and rib 38 are matched is a common matching method in the art, and will not be described in detail. Rib 38 is actually a group of ribs 38. This group of ribs 38 is arranged along the axial direction of the saw cylinder, that is, the transverse direction of the whole machine. The gap between the ribs is used for the saw blade of the saw cylinder to extend a part from the rear side of the rib, which is used to hook the short fibers on the cotton seeds that are discharged from the outlet of the working box.

[0064] The gaps between the 38 ribs are generally smaller than the waist diameter of the cottonseed. This means that, except for a few infertile seeds, cottonseeds cannot pass through the gaps between the 38 ribs and instead descend along the 38 ribs. Therefore, it can be seen that... Figure 1 The upper and middle ribs 9 and the lower ribs 2 are on the left side of the figure, and the transfer channel 6 shown in the figure between them is the downward channel for cotton seeds. The right side is the channel for removing impurities and the channel for absorbing short fibers.

[0065] In view of Figure 4 The illustrated structure represents the general configuration of the current work box and rib 38. This configuration applies to the fit between the upper rib 9 and the upper work box 11, as well as the fit between the lower rib 2 and the lower work box 5. The relationship between the two sets of work boxes and rib 38 will not be explained separately.

[0066] In terms of general structure, the work box has an inlet and an outlet. Ribs 38 partially cover the outlet of the work box. The portion of the saw blade protruding from the gaps between ribs 38 that mainly serves the stripping function is the part that enters the work box, thus forming a structure like... Figure 1 The first working point 10 and the third working point 4 shown are where most of the stripping work is done.

[0067] For ease of description, the assembly formed by the upper saw cylinder 8 and the upper rib 9 is called the upper stripping section; correspondingly, the assembly formed by the lower saw cylinder 3 and the lower rib 2 is called the lower stripping section.

[0068] As mentioned earlier, the upper stripping section is equipped with two waste removal components, including a first part located on the rear side of the upper saw cylinder 3, such as... Figure 1 The second row of miscellaneous knives 20 is shown in the diagram.

[0069] Unlike existing technologies, in embodiments of the present invention, an upper suction part is used instead of an upper air nozzle. Although it also uses air force to suck away short fibers, the configuration is different from that of the air nozzle 25.

[0070] The upper lint suction section is located on the upper rear side of the first part or on the upper side of the part of the first part that mates with the upper saw cylinder 8, so as to suck away the short lint stripped off by the upper lint stripping section.

[0071] In terms of form, if the upper suction part is located on the upper side of the part that mates with the upper saw cylinder 8, the inlet shape of the upper suction part can be exactly the same as the inlet of the air nozzle 25, and cover the upper right part of the upper saw cylinder 8.

[0072] Since the lower working box 5 and the aforementioned lower stripping section can be configured entirely in the prior art, they will not be described in detail here. In the embodiments of the present invention, the focus is mainly on the improvement of the upper part.

[0073] In summary, since the upper suction section is located above, for example, the second row of debris cutters 20, regardless of its shape, it will not obstruct the falling of the debris attached to the second row of debris cutters 20. Therefore, only one debris removal assembly needs to be configured, which is located in the lower part of the inner cavity of the double-layer sawtooth delinting machine. This assembly serves as the debris removal component for both the lower and upper delinting sections.

[0074] In terms of position, the impurity removal assembly can use the configuration of the existing technology, which is located on the rear lower side of the third row of impurity cutters 26, and is used to receive the impurities discharged from the two stripping sections.

[0075] For the air nozzle 25, which is equivalent to the existing lower air nozzle, its position can remain unchanged and is still located below the debris removal assembly. In the embodiments of the present invention, it is also similar to the conventional lower air nozzle, which is used to suck away the short fibers peeled off by the lower stripping part.

[0076] As mentioned above, in the preferred embodiment, a brush 14 is provided. The brush 14 is a common component in cotton processing equipment, mainly used to brush off seed cotton adsorbed on, for example, a dust cage. In the embodiment of the present invention, it is used to transfer the short fibers peeled off from the upper saw cylinder 8 to the brush 14. It should be known that the brush 14 has a stronger adhesion to cotton fibers (here, short fibers) than the saw teeth on the upper saw cylinder 8.

[0077] In addition, Figure 1 In the illustrated structure, the upper saw cylinder 8 rotates clockwise, and the brush 14 rotates counterclockwise. The first linear velocity of the top circle of the brush 14 is greater than the second linear velocity of the top circle of the upper saw cylinder 8. At this time, the velocity of the brush 14 at the junction of the two is faster than that of the saw cylinder 8. It should be understood that the upper saw cylinder 8 hooks the short fibers, causing the short fibers to float backward except for the part supported on the saw teeth. The brush 14 has a relative backward brushing velocity with respect to the upper saw cylinder 8, thereby transferring the short fibers from the saw teeth to the brush 14 without damage. This method of bending the short fibers by speed and thus carrying them is easy to remove from the brush by suction, for example. The same principle applies to the saw cylinder.

[0078] The first linear velocity is 1.25 to 1.40 times the second linear velocity. In a more preferred embodiment, the first linear velocity is 1.27 to 1.32 times the second linear velocity. More preferably, the first linear velocity is 1.3 times the second linear velocity.

[0079] Regarding the fit between the brush 14 and the upper saw cylinder 8, the bristles of the brush 14 need to be inserted between the saw blades. The insertion amount should not be too large, just enough to reach the root of the saw teeth, so as to reduce the friction on the brush 14.

[0080] The amount of material used should not be too small, otherwise the short fibers at the root of the saw blade teeth will not be cleaned properly.

[0081] The amount of intervention can slightly exceed the root of the saw blade teeth, but the excess should not exceed 2mm.

[0082] Furthermore, different factories have different requirements for the delinting process, which leads to variations in the moisture content of the short fibers. Generally speaking, if the short fibers are relatively dry, the amount of material introduced can be relatively small; if the short fibers are relatively damp, the delinting process becomes more difficult, and the amount of material introduced can be relatively large. Different cotton processing plants can configure the amount of material introduced based on their own processing characteristics.

[0083] Based on the above-mentioned cooperation between the upper saw cylinder 8 and the brush 14, it is required that the axis of the brush 14 be parallel to the axis of the upper saw cylinder 8.

[0084] In terms of positional relationship, the second row of miscellaneous knives 20 and Figure 1 The partition 13 shown in the example is located on the upper rear side of the upper saw cylinder 8. Placing the brush 14 in this position will not affect the normal operation of the second row of miscellaneous blades 20. Moreover, from the perspective of the upper stripping section with a conventional layout, this part is an empty area, and placing the brush 14 here will not add too much extra space.

[0085] Figure 1 and Figure 3 In the illustrated structure, a cover plate 34 is provided above the brush 14 to close the space above the brush 14 from the top, so as to regulate the airflow of the brush 14 and make it work more on the upper rear side of the brush 14, so as to avoid the brush 14 from being damaged by the excessive space.

[0086] Accordingly, from Figure 1 and Figure 3 As can be seen in the illustrated structure, a first row of debris cutters 14, which is included in the upper debris removal component, is provided between the brush 14 and the inlet of the upper suction part to remove heavy debris from the brush 14.

[0087] As mentioned earlier, the impurities remaining in the cottonseed stream are mostly heavy impurities such as pebbles, which are much heavier than short fibers. When the brush 14 rotates, the pebbles will be located on the centrifugal side of the brush 14.

[0088] Figure 1 and Figure 3 In the middle, the brush 14 rotates counterclockwise, and the first row of miscellaneous blades 17 are located on the right side of the brush 14 with the blades facing downwards, thus separating the impurities from the short fibers.

[0089] The suction power of the absorbent material has a direct transporting effect on short fibers with a relatively large surface area, but it has almost no transporting effect on heavy debris such as pebbles. For example, heavy debris such as pebbles will fall down after losing upward speed.

[0090] The first row of miscellaneous blades 17 and the brush 14 are roughly tangent to the top circle of the brush 14, or slightly deviated outward by less than 3.5mm.

[0091] exist Figure 1 and Figure 3 In the illustrated structure, the first row of scrap blades 17 and the mounting plate of the first row of scrap blades 17 form the front sidewall of the upper suction part inlet. The front sidewall is, for example, a... Figure 1 and Figure 3 The front pile channel 15 shown in the figure has a rear pile channel 16 on the rear side of the front pile channel 15. The upper pile suction channel is defined between the front pile channel 15 and the rear pile channel 16. The suction capacity of the channel can be referred to the conventional air nozzle 25. The design basis is clear and will not be described in detail here.

[0092] Furthermore, in order to facilitate the downward movement of impurities, an arc-shaped plate 18 is connected to the lower end of the rear feed plate 16 to collect material downward and forward. In other words, the axis of the arc-shaped plate 18 (it should be known that the arc-shaped plate in the mechanical field is essentially a cylindrical panel) is on the side where the brush 14 is located, and in a preferred embodiment, the axis of the arc-shaped plate 18 is collinear with the axis of the brush 14.

[0093] In addition, such as Figure 1 and 3 As shown, the end of the arc plate 18 is connected to a downward and backward extending slip plate 21 to prevent impurities discharged from the upper stripping section from colliding with the upper saw cylinder 8.

[0094] Accordingly, the first part includes a second row of scrap blades 20 that cooperate with the upper saw cylinder 8. As mentioned earlier, the arrangement of the second row of scrap blades 20 can be similar to that of conventional scrap blades, the only difference being that the installation position of the second row of scrap blades 20 can take into account the downward flow of impurities separated from the upper layer. (Comparison) Figure 1 In the traditional configuration of the third row of miscellaneous blades 26, the positional relationship between the second row of miscellaneous blades 20 and the first baffle plate 22 mainly considers the downward flow of upper impurities, without making specific restrictions on other differences.

[0095] It should be noted that the debris discharge blade is usually installed using a crossbeam, for example, fixed to the wall panel 33. For example, the upper end of the first debris discharge plate 22 is adjacent to the corresponding crossbeam.

[0096] Correspondingly, a downward channel for impurities is formed between the first baffle plate 22 and the straightening plate 21; the upper end of the first baffle plate 22 is connected to the second row of impurity cutters 20, forming a... Figure 3 The left side of the road is shown in the example.

[0097] exist Figure 1 and Figure 5 As can be seen in the illustrated structure, the impurity removal assembly is located in the middle of the double-layer sawtooth delinting machine in the front-to-back direction to collect impurities over the maximum range. Furthermore, the impurity removal assembly inlet has a waste-draining plate 24 that forms a receiving hopper; the waste-draining plate 24 extends upward and backward from the upper edge of the inlet, and the end of the extension can be the inner wall of the integral outer shell, or it can directly receive the aforementioned waste-following plate 21, or it can be located behind the waste-following plate 21, equal to or higher than the lower edge of the waste-following plate 21.

[0098] exist Figure 1 The lower part is visible, and a second baffle plate 23 is provided in the middle of the lower shell. The second baffle plate 23 is mainly used to block the impact of the debris discharged from the impurity channel formed by the main first baffle plate 22 and the straightening plate 21 on the lower stripping part, and to guide these debris to the flow plate 24 as much as possible. Therefore, the second baffle plate 23 is mainly for the protection of the lower stripping part, and is shielded on the rear upper side of the lower saw cylinder 3.

[0099] From another positional perspective, the second baffle plate 23 is positioned above the impurity discharge assembly and opposite to the impurity flow plate 24, so that the impurities discharged from the upper layer can be guided to the impurity flow plate 24, or directly to the impurity discharge assembly.

[0100] in addition, Figure 1 and Figure 5 The debris removal assembly shown is called debris removal auger 27.

[0101] Next, let's look at the feeding section 12. The feeding section 12 is located at the inlet of the upper working box. It is a separate feeding section used to evenly distribute cotton seeds.

[0102] Figure 2 In this context, the feeding unit 12 includes:

[0103] The enclosure is configured as a top-in, bottom-out enclosure, and is rectangular in shape.

[0104] The feeding rollers 30 are a pair of feeding roller shafts 30 configured at the entrance of the box. Cotton seeds are fed through the pair of feeding roller shafts. The feeding speed is positively correlated with the rotation speed of the feeding roller shafts, making it easy to control the feeding speed.

[0105] Furthermore, a magnetic plate 31 is also provided inside the box. The magnetic plate 31 is located below the feeding roller 30 and extends forward and downward from the rear wall of the box.

[0106] An inspection door 29 is provided on the panel opposite the magnetic plate 31 of the housing for periodically cleaning the ferromagnetic debris adsorbed on the magnetic plate 31.

[0107] To better control the cottonseed flow, a feed plate 28 extending backward and downward from the front wall of the box is provided on the lower side of the inspection door 29 inside the box.
