Abstract
Description
Technical Field
[0001] This utility model relates to a cotton stalk baler with a cutting table. Background Technology
[0002] Cotton is an important economic crop in my country, with a vast planting area. Cotton stalks (hereinafter referred to as cotton stalks) are a major byproduct of cotton cultivation. Currently, the main methods of handling cotton stalks are crushing and returning them to the field or burning them after harvest. This relatively singular approach to utilizing cotton stalks has resulted in enormous resource waste and serious environmental pollution. As a biomass resource rich in cellulose, hemicellulose, and lignin, cotton stalks can be used for biomass energy, feed, fertilizer, industrial raw materials, and more, possessing immense potential utilization value.
[0003] The comprehensive utilization of cotton stalks is still in its early stages, with an incomplete industrial chain and a lack of effective collection, storage, and transportation systems. Clearly, collection is a prerequisite for the comprehensive utilization of cotton stalks. To achieve effective and high-value utilization of cotton stalks, it is urgent to overcome the bottlenecks in collection and transportation, transforming them into valuable renewable resources and propelling the industry towards a mature and healthy development path.
[0004] Currently, cotton stalks are mainly harvested by cutting (picking up), chopping, and loading onto trucks. The stalks are in a loose state, making transportation and storage difficult and causing inconvenience to downstream users.
[0005] In view of this, some integrated balers have emerged, such as the 4MG-275 self-propelled cotton stalk combine harvester developed by the Biomass Energy Engineering Technology Research Center of the Chinese Academy of Agricultural Mechanization Sciences. It can complete harvesting (or picking up), feeding, chopping, throwing and packing, hydraulic tipping unloading and loading in one go.
[0006] For example, the Maoniu 4MGZ-2500 self-propelled cotton stalk combine harvester developed by Dezhou Huabei Agricultural Machinery Equipment Co., Ltd. is used for picking up or harvesting cotton stalks after they have been pulled up in the field. It can complete the picking (or harvesting), feeding, chopping, throwing and packing, hydraulic tipping unloading and loading operations in one go. In addition, to achieve different cotton stalk harvesting modes, a cutting header can be replaced to suit the direct cutting method of cotton stalk harvesting in western regions.
[0007] As mentioned above, most cotton stalk combine harvesters currently on the market chop the cotton stalks and feed them into a given hopper. The cotton stalks are in a disordered and loose state in the hopper, with high porosity and relatively loose structure, which affects subsequent storage and transportation.
[0008] It should be noted that the above background technology is technical information acquired by the inventor in order to deduce the relevant technical problems or obtained in the process of designing this utility model, and does not mean that the above background technology was already prior art before this application, especially the technical content of the cognition and confirmation of the relevant technical problems.

[0028] The cotton stalk baler with a cutting platform according to an embodiment of this utility model has a chassis that can be towed by a tractor or other trailer via a traction unit. The cutting platform, located at the front of the chassis, harvests the cotton stalks after the cotton is harvested. The stalks are then fed into the baling unit via a feeding unit. The baling unit bales the stalks to a predetermined quantity, and after baling, the bales are unloaded. Baling makes the cotton stalks relatively dense, preventing them from scattering and facilitating storage and transportation. Furthermore, the bales can be temporarily left in the cotton field instead of being unloaded at the field edge, reducing the volume requirement of the baling unit. Simultaneously, the maximum total load capacity of the cotton stalk baler with a cutting platform is relatively low, reducing energy consumption during operation. Attached Figure Description

[0039] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that the chassis 6 used in the cotton stalk baler with a cutting platform provided in the embodiments of this utility model is equivalent to a towing chassis. It is obvious that the towing unit 1 adapted to the towing chassis is located on the front side of the chassis 6, and the towing unit is clearly not located on the lower side of the chassis 6. For cotton stalk harvesting, for example, the position of the cutter 27 is relatively closer to the ground, typically less than or equal to 100mm from the ground. For the towing chassis, the lowest point of its towing unit 1 is typically not less than 200mm. For cotton field applications, the lowest point of the towing unit 1 of the towing chassis can be higher, roughly equivalent to or higher than the lowest point of the towing unit 1 of a semi-trailer, for example, greater than or equal to 300mm. The towing unit 1 may interfere with the cotton plants, but it has little impact on their passage and will not affect the harvesting of the cotton plants.
[0040] Given that, in the embodiments of this utility model, cotton plants are first harvested to form cotton stalks and then bundled, and cotton fields are often planted in rows, the cotton plants lie down after harvesting, which facilitates the gathering and transport of the cotton stalks.
[0041] It should be understood that, both the chassis 6 and the entire cotton stalk baler with cutting platform meet the orientational characteristics of the vehicle technology field. The end where the traction unit 1 is located is the front end of the chassis 6, and vice versa. Furthermore, it is clear that in the embodiments of this utility model, there is a definite up and down direction. However, it should be understood that in the mechanical field, up and down does not specifically refer to directly above or below, but usually indicates a height difference. Moreover, in the embodiments of this utility model, "up," "down," and other terms such as left, right, inside, outside, front, and rear, as well as similar expressions, are for illustrative and explanatory purposes only, and are intended to prevent misunderstanding by those skilled in the art.
[0042] Similarly, statements that are mutually explanatory, such as vertical or horizontal, are also for the purpose of explanation or clarification.
[0043] Given that the front and rear directions are determined, the left and right directions are also determined. In the field of vehicle technology, the front and rear direction is also called the longitudinal direction, the head and tail direction, or the longitudinal direction, while the left and right direction is also called the width direction, the lateral direction, or the transverse direction.
[0044] 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 in use and operation, in addition to those depicted in the accompanying drawings.
[0045] 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.
[0046] 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.
[0047] 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 exact geometric characteristics corresponding to those terms. For example, the bolt head of a hexagonal head bolt is actually a hexagonal prism, and the ends of the bolt head are rounded.
[0048] In the embodiments of this utility model, the chassis 6 of the cotton stalk baler with cutting platform provided is a traction chassis as described above. However, it should be noted that for special equipment, the chassis 6 can be a powered chassis 6.
[0049] Correspondingly, in some embodiments of this utility model, the traction unit 1 located on the front side of the chassis 6 is also provided with a transmission part for introducing power from, for example, a tractor. If the chassis 6 has its own power unit, the traction unit 1 does not need to be provided with the transmission part as described above.
[0050] exist Figure 1 and Figure 9 In the illustrated structure, chassis 1 has only one pair of wheels, positioned at the rear. When parked alone, the cutter head 2 and other components may rest on the ground, potentially causing damage. Therefore, support legs 23 are provided on the front side of chassis 6, specifically at the towing unit 1, similar to the configuration of support legs on a semi-trailer.
[0051] Furthermore, the support leg 23 is mounted on the bracket of the traction unit 1 via an adjusting rod 18. The adjusting rod 18 is mounted on the bracket in a generally vertical manner by means of welding, riveting, or bolting. The adjusting rod 18 has vertically distributed adjusting holes. The support leg 23 is shown in the figure as a rectangular tube structure, which can be fitted onto the adjusting plate 18. Correspondingly, the adjusting rod 18 can also be a rectangular tube structure with a relatively small cross-sectional dimension. The support leg 23 has three bolt holes in the vertical direction. The support height of the support leg 23 can be adjusted by aligning the bolt holes with the adjusting holes at different positions. After adjustment, bolts 19 and nuts 20 can be used for tightening.
[0052] Regarding chassis 6, there is also an auxiliary support, specifically at the cutter head section 2, see [link / reference]. Figure 3The two ends of the roller 25 located at the front of the header section 2 are mounted on the frame 29, with the rest suspended in the air. Behind it is a set of horizontally arranged cutters 27. It is necessary to ensure that the cutters 27 and the roller 25 maintain a predetermined distance from the ground. This predetermined distance cannot be effectively guaranteed in farmland with poor flatness by relying solely on trailer towing and wheel support. Therefore, a height-fixing wheel is also provided on the lower side of the header section 2. Figure 9 The position of the height-fixing roller can be observed. It is located on the lower side of the cutting platform 2. There can be one set on each side, or it can be set directly below the cutting platform 2.
[0053] During the movement of the chassis 6, the height-fixing wheel can be suspended in the air. Only when, for example, the position of the cutter 27 is lower than or equal to the set value, will the height-fixing wheel come into contact with the ground. In other words, the height-fixing wheel can also be understood as the lower limit component of the cutting platform 2.
[0054] It is obvious that, under the condition that power is introduced through the traction unit 1, one aspect is the driving power, that is, the driving power is introduced through traction. Therefore, the aforementioned height-fixing wheels and the wheels on the chassis 6 are both considered driving wheels. If the traction unit 1 itself constitutes the power unit, the chassis 6 can also be equipped with another pair of wheels at the traction unit 1. However, this pair of wheels can be either drive wheels or driving wheels. And located at... Figure 1 The pair of rearward-biased wheels at the center position can serve as either the running wheels or the drive wheels, meaning the chassis 6 can be configured for two-wheel drive or four-wheel drive. Similarly, if the towing unit 1 has the power to move based on the towing of the trailer, all the wheels on the chassis 6 serve as running wheels.
[0055] Regarding the cutting platform 2, as mentioned earlier, it is located behind the traction unit 1. Here, "behind" is only used to indicate the general orientation, not the precise orientation. The lowest point of the cutting platform 2 is relatively low to facilitate cutting the cotton stalks near the root, while also avoiding direct interference between the cutting platform 2 and the ground. As mentioned earlier, a height-fixing wheel is used to determine the distance between the cutting platform 2 and the ground.
[0056] The cutting section 2 is used to cut the cotton plant near the root, causing the plant to tilt backward. Figure 3 The roller 25 shown is in Figure 3 Rotate counterclockwise to tilt the plant backward, ensuring that the cotton plant is roughly tilted backward before being cut. This allows the cotton stalks to tilt backward when cut, facilitating the combing and transport of the cotton stalks.
[0057] In some implementations, the roller 5 located at the front of the header section 2 can also push the cotton plant forward, causing it to tilt forward to facilitate the operation of the cutter 27. Due to inertia, the cutter 27 also pushes forward during the cutting process, acting as a shovel. The cotton stalk formed after the cotton plant is cut is equivalent to the main stem sliding towards the upper surface of the guide plate on the header section 2 where the cutter 27 is located. At this time, the branches of the cotton stalk are equivalent to the upper surface of the guide plate that slides backward, which is beneficial for the smooth guidance of the cotton stalk.
[0058] Furthermore, a feeding section 3 is provided to convey the cotton stalks harvested by the header section 2 backward. Therefore, the feeding section 3 is located on the rear side of the header section 2. As mentioned above, due to factors such as inertia, the cotton stalks move backward relative to the header section 2 after harvesting, but this movement may be relatively scattered. The cotton stalks are guided by the aforementioned guide plate and then purposefully fed backward by the feeding section 3.
[0059] Furthermore, under these conditions, the feeding unit 3 feeds material in a given direction based on the purpose of active feeding, and the purpose of feeding is the direction of the bundling unit 4. Figure 8 The feeding inlet 65 shown is used to forcibly feed cotton stalks into the bundling section 4. During the forced feeding process, the cotton stalks are squeezed, some branches and the woody parts of the trunk break off, and are gradually compressed due to the pull of the fibers.
[0060] Accordingly, the baling section 4 is located at the rear of the chassis 6 and behind the feeding section 3. The baling section 4 has a predetermined volume, and the baling timing is determined by, for example, the load-bearing condition of the rollers of the baling section 4. For example, the uppermost roller, as the inner cavity of the baling section 4 gradually fills, begins to bear force. Based on the reaction of the cotton stalks, the upward force exerted by the cotton stalks on the roller bearing will increase. By monitoring the upward force on the uppermost roller, it is determined whether the cotton stalks in the inner cavity of the baling section 4 have reached the predetermined amount.
[0061] Then, the bundling component of the bundling section 4 releases the binding material, and the cotton stalks located in the bundling section 4 are unloaded after being bundled. The resulting bundled cotton stalks are easy to process later.
[0062] It should be noted that in the field of baling technology, the technology of the baling part 4 suitable for baling cotton stalks is relatively mature. Therefore, any technology suitable for baling cotton stalks can be adopted by those skilled in the art. The following is in conjunction with the appendix to the instruction manual. Figures 7-9 The specific structure of the bundling part 4 in one embodiment is described.
[0063] See Figures 7-9 The bundling section includes a packing cavity and several rollers distributed on the packing cavity, as well as a feeding device for providing the bundled material and a drive system for driving the rollers. A pressure sensor is also provided to detect whether the amount of cotton stalks in the bundling section 4 has reached a predetermined amount.
[0064] The baling compartment consists of a front compartment 70 and a rear compartment 72. The front compartment 70 and the rear compartment 72 can be separated in a predetermined manner to facilitate unloading. At the same time, after the front compartment 70 and the rear compartment 72 are closed, baling operations can be carried out.
[0065] The front compartment 70 is the compartment part installed on the chassis 6, while the rear compartment 72 is installed on the front compartment 70 via a transversely arranged upper pivot. The upper pivot of the rear compartment 72 is the pivot axis, which can be used for opening and closing the compartment.
[0066] Accordingly, the bundling compartment forms a transverse cylindrical space within the compartment based on the combination of the forward compartment 70 and the aft compartment 72. Here, transverse placement is based on the axis of the cylindrical space, that is, its axis is transverse.
[0067] The front compartment 70 and the rear compartment 72 can each form a semi-cylindrical cavity (i.e., a 180° semi-cylindrical cavity), and the two corresponding semi-cylindrical cavities fit together to form a bundling compartment. The rear compartment 72 forms a swing pair through the mounting of an upper pivot on the front compartment 70, thereby providing a material unloading drive device for driving the rear compartment 72 to rotate around the upper pivot to open the rear compartment 72, so that the bundled cotton stalks can be unloaded. The material unloading drive device resets, causing the rear compartment 72 to reset and realize the closing of the compartment.
[0068] exist Figure 7 In the illustrated structure, two unloading cylinders 63 are used as the unloading drive device. The two unloading cylinders 63 are hinged to the chassis 6 on the left and right sides or to the wall panel of the front compartment 70. The push rod of the unloading cylinder 63 is hinged to the wall panel of the rear compartment, thereby forming a cylinder linkage mechanism (a type of pneumatic-hydraulic linkage mechanism).
[0069] It is readily understood that when the unloading cylinder 63 reaches the predetermined extension of its push rod, the opening of the rear compartment 72 relative to the front compartment 70 should be sufficient to allow the bundled cotton stalks to roll out. Those skilled in the art can easily design such a system, and further details are omitted here.
[0070] The rollers in the roller group 60 are arranged in a relatively uniform circumferential pattern on the baling chamber, provided that the feeding inlet 65 and the baling material inlet are allowed to pass. In a preferred embodiment, the rollers are located inside the baling chamber, which is referred to as the baling cavity.
[0071] exist Figure 7 In the illustrated structure, the baling chamber that defines the baling cavity does not necessarily need to be defined by the shell; it can also be defined by the rollers. Furthermore, there are no special requirements for sealing. As a biomass material, the cotton stalks are intertwined and are not easily leaked from the gaps between the rollers.
[0072] exist Figure 8 and Figure 9In this system, adjacent rollers have a certain gap, but it should not be too large. The main consideration is the pushing and rotation of the cotton stalks entering the baling chamber. If the gap is too large, the rotation of the cotton stalks will be difficult to control. The gap between adjacent rollers is usually no greater than the roller radius, and in a more preferred embodiment, it is no greater than half the roller radius.
[0073] As mentioned earlier, a feeding inlet 62 needs to be provided for the circumferential distribution of the rollers in the baling chamber to facilitate the feeding of cotton stalks. The rollers are rotating components. After the cotton stalks enter the baling chamber, they will rotate under the drive of the rollers. It is required that all rollers rotate in the same direction, for example, all of them rotate clockwise. Under the drive of the rollers, the collection of cotton stalks will generate a counterclockwise rotation.
[0074] Once the cotton stalks fill the baling chamber, the rotating bundle of stalks will gradually be compacted as they enter. When, for example, the baling material feeding device introduces the material through the preset feeding port on the front chamber 70, and the baling material is, for example, a baling net, the bundle of cotton stalks will automatically pull the baling net along with the cotton stalks as they roll. After baling, for example, three to five times, the baling net is cut off, and then the material is unloaded.
[0075] If strapping is used, corresponding strapping grooves need to be pre-drilled on the roller. In the preferred embodiment, materials that can be easily captured by the cotton stalk assembly surface, such as strapping nets or strapping plastic films, are still used. Strapping, which is not easily captured by the cotton stalk assembly, is a secondary choice.
[0076] Accordingly, the bundling material feeding device is installed on the front compartment 70 of the bundling compartment; the front compartment 70 is correspondingly equipped with a feeding port, such as... Figure 8 The network port 69 is shown in the diagram.
[0077] In addition Figure 8 In the illustrated structure, the lashing feeding device is located on the upper front side of the front compartment 70, including, for example, a net roll support assembly 67 and a net feeding and cutting assembly 68. Since such lashings are common configurations in the field of lashing, they will not be described in detail here. This utility model is just a conventional application of such lashings.
[0078] In contrast, the bundled material is also fed in through the gap between the two rollers, that is, the gap between the two rollers constitutes the entry channel for the bundled material and is aligned with the feed port 69.
[0079] Regarding the feeding inlet 65 of the bundling cavity. Figure 8 Combination Figure 9 As can be seen, the feed inlet 65 is located between two adjacent rollers on the lower front side of the front compartment, with a given distance between the two adjacent rollers, which is 1 to 1.8 times the roller diameter.
[0080] exist Figure 9 In the middle, the feeding inlet 65 receives the discharge outlet 34 of the feeding part 3.
[0081] Regarding the drive system, in the embodiments of this utility model, it is mainly used to drive each roller to rotate in the same direction. The motion is relatively simple, and it is not necessary to stop rotating during unloading. The control method is also relatively simple. Figure 7 The main implementation uses a chain drive system 62, which is clearly shown in the figure and will not be described in detail here.
[0082] If the drive system has good sealing performance, a gear system can also be used for drive. In the preferred embodiment, a chain drive mechanism with relatively low requirements for the working environment is used. Even if the chain drive mechanism is exposed, its working reliability can still be easily guaranteed.
[0083] Regarding the setting of the pressure sensor, as mentioned above, it can be, for example, a pressure sensor for monitoring the roller seat of the uppermost roller in the front compartment 70 or the rear compartment 72. Based on the above description, it is easy to understand that the cotton stalks will gradually accumulate from bottom to top until the baling chamber is full. As the cotton stalks gradually enter, the pressure value monitored by the pressure sensor will gradually increase until it reaches a preset value. Then, the feeding unit 3 can stop feeding, bundle the cotton stalks in the baling chamber, and then unload the material. After the baling chamber is closed, the feeding unit 3 will feed the baling chamber again.
[0084] Accordingly, the feeding transmission assembly of the feeding unit 3 may include a clutch to control the feeding start and stop states of the feeding unit 3.
[0085] In some implementations, to avoid congestion problems that may occur when the feeding unit 3 stops feeding due to continuous feeding from the preceding stage, the process of strapping, for example, can be temporarily stopped, such as when the trailer is being used.
[0086] In some embodiments, such as Figure 4 and Figure 5 As shown, both the cutting section 2 and the feeding section 3 have a certain capacity, and even if feeding is stopped for a short period of time, serious congestion will not occur if the capacity is not at its maximum.
[0087] In a preferred embodiment, the upper pivot is a roller shaft of a roller. When the chain drive system 62 is used, the drive chain can rotate adaptively when relative rotation occurs between the front and rear compartments. In other words, when the upper pivot is a roller shaft of a roller, it does not affect the normal operation of the drive system under the conditions of opening and closing the compartments.
[0088] exist Figure 8 In the illustrated structure, the rear end face of the front compartment 70 is tilted downward and backward, and the angle between it and the horizontal plane is 75° to 88°, that is, slightly tilted, which can ensure reliability under closed conditions, and the angle is preferably greater than or equal to 85°.
[0089] exist Figure 8 In the illustrated structure, a rearward unloading guide 74 is provided on the lower side of the bundling compartment. The unloading guide 74 can be fixed. Considering that the material should be guided at an angle downward during unloading, but the angled downward guidance means that the unloading guide 74 needs to be arranged at an angle downward. At this time, the unloading guide 74 will affect the passability of the chassis 6. Therefore, in the preferred embodiment, the front end of the unloading guide 74 is hinged to the lower side of the front compartment 70, thereby forming a swing frame.
[0090] Accordingly, a buffer reset device is provided to provide buffering when the unloading guide 74 is supported by material and swings downwards, and swings downwards under pressure until it contacts the ground. After unloading is completed, the unloading guide 74 swings upwards and resets under the action of the buffer reset device. The reset position is, for example, close to the lower side of the rear compartment 72, reducing the impact on the passability of the chassis 6.
[0091] Rigid constraints can be set in the reset position, such as baffles or stop pins fixed on the chassis 6, to prevent the unloading guide 74 from affecting the closing operation of the bundling compartment when in the reset state.
[0092] As mentioned above, in some embodiments, feeding of the feeding part 3 needs to be stopped in conjunction with binding, which may cause material blockage. Therefore, in a preferred embodiment, the feeding part 3 has a material blockage discharge mechanism or structure.
[0093] exist Figure 6 As can be seen in the illustrated structure, the feeding section 3 has two parts: a front feeding section and a rear feeding section. The front feeding roller 38 and the rear feeding roller 36 are located in... Figure 5 and Figure 6 In the indicated state, all rotations are counterclockwise. The front feed roller 38 and the rear feed roller 36 will push the cotton rod to move backward from the bottom. Therefore, the feeding part 3 is also equipped with a material trough 35, and the corresponding feed rollers are installed in the material trough 35. Obviously, the material trough 35 guides the material from front to back, and the trough walls are on the left and right sides. Figure 6 The central tank wall is provided by side plate 45, and the corresponding feed rollers are installed on side plate 45.
[0094] For ease of explanation, the bottom plate of the trough 35 will be referred to as the chute. Figure 6 The front slide 42 and rear slide 47 shown are illustrated, wherein the front slide 42 is a slide fixedly mounted on the chassis 6, and the rear slide 47 is connected via, as shown in the figure Figure 6 The pivot 48 shown is mounted on the chassis 6, thus providing a degree of freedom for swinging.
[0095] Correspondingly, the pivot 48 is located at the rear end of the rear slide 47, while a hinge 50 is installed on the lower front side of the rear slide 47. This hinge 50 is connected to... Figure 7The anti-blocking cylinder 53 shown is connected to form a rotating pair. The cylinder body of the anti-blocking cylinder 53 is hinged to the chassis 6 or other relatively static components to form a hydraulic linkage mechanism, which can drive the rear slide plate 47 to open downward to remove the blockage.
[0096] The front slide plate 42 forms the bottom plate of the front chute, and the rear slide plate 47 forms the bottom plate of the rear chute. Obviously, in the reset state of the anti-blocking cylinder 53, the rear slide plate 47 and the front slide plate 42 need to overlap or be connected sequentially. Figure 6 The illustrated structure is a continuous connection, and a relatively reliable continuous connection can be formed simply by controlling the extreme angle position of the rotating shaft 48.
[0097] In addition, both ends of the front slide 42 and the rear slide 47 have flanges 41 to improve the overall rigidity.
[0098] At the same time, Figure 6 In the illustrated structure, the upper surface of the rear slide plate 47 is also provided with a reinforcing rib 49, which extends in the front-back direction and is consistent with the flow direction of the cotton rod.
[0099] In addition, the reinforcing rib 49 can also be set on the lower surface of the rear slide plate 47.
[0100] exist Figure 5 and Figure 6 In the illustrated structure, the feeding section 3 uses a feeding roller for feeding. In the figure, the feeding roller is provided with teeth that are arranged in a spiral pattern, which can better comb the cotton stalks and make the cotton stalks move in a roughly back-and-forth direction.
[0101] Furthermore, to prevent the cotton stalks from being rolled upwards by the feed rollers, a corresponding unloader is provided, such as... Figure 5 and Figure 6 The front unloader 37 and rear unloader 39 are shown. The unloader has unloading teeth 52 distributed laterally. Along the axial direction of the feed roller, the unloading teeth 52 are located between adjacent teeth, so as to tuck the cotton stalks that are rolled up by the feed roller.
[0102] The helix is a three-ended helix or a four-ended helix. Figure 5 and Figure 6 The illustrated structure uses a three-headed helix, which has relatively low structural complexity.
[0103] Furthermore, each spiral has a tooth located on the same toothed disc, which is perpendicular to the axis of the feed roller; from Figure 5 As can be seen, a set of 11 gear discs are mounted on the tube shaft 43. Each gear disc has three teeth. The different gear discs have different mounting angles in the circumferential direction of the tube shaft 43, thus forming three helices.
[0104] Accordingly, the unloading tooth 62 is located between adjacent toothed discs.
[0105] from Figure 5 and Figure 6 As can be seen, the teeth are spiral-shaped on the toothed disc, forming a spiral toothed disc. The tooth profile of the teeth gradually decreases from the centripetal side to the centrifugal side, and the impact surface of the tooth profile is curved, resulting in relatively high overall stiffness.
[0106] In addition Figure 5 and Figure 6 In the illustrated structure, the unloader includes an upper crossbeam 46 located above the rear side of the corresponding feed roller, which serves as the mounting base for the unloading tooth 52.
[0107] exist Figure 3 and Figure 4 In the illustrated structure, the cutting table 2 includes a shift roller 25 and a cutter assembly arranged sequentially from front to back, as well as an auger.
[0108] Among them, the shift roller 25 is positioned horizontally on the front side of the cutter assembly, in Figure 3 In the illustrated structure, the pusher roller 25 rotates counterclockwise to push the cotton plants backward.
[0109] The cutting assembly includes a guide plate and a set of cutting blades 27, similar to shovels, distributed along the front edge of the guide plate and evenly arranged laterally. In some embodiments, the cutting blades 27 can reciprocate laterally or rotate like a chainsaw to form lateral cuts in addition to the shoveling cuts produced by the shovels.
[0110] Regarding the auger, it is mainly used for material handling. Relatively speaking, the width of the cutting platform 2 can be relatively large to harvest more cotton plants at a time. However, considering factors such as passageway and the storage and transportation of bundled cotton stalks, the width of the baling section 4 needs to be relatively small. Therefore, the auger adopts a two-section structure and is arranged laterally on the chassis 6. One section of the two-section structure is a left-handed auger 32, and the other is a right-handed auger 28, which pushes the cotton stalks towards the middle laterally, which is equivalent to reducing the width. This constrains the width of the discharge port 34 to be relatively narrow, which is adapted to the relatively narrow baling section 4.
[0111] exist Figure 4 In the illustrated structure, a guide cover 30 is provided above the guide base plate to form a discharge channel that runs through the front and back and is correspondingly connected to the feed section 3 on the rear side. The aforementioned discharge port 34 is the outlet of the discharge channel.
[0112] As mentioned earlier, there are two main types of power sources: one is the driving power of the chassis 6, and the other is the driving force of the other moving parts. The cotton stalk baler with cutting platform can be powered by its own power unit or can be powered by the trailer.
[0113] Accordingly, if the trailer is connected to the power supply, the traction unit 1 is equipped with a transmission system.
[0114] Figure 2 In this configuration, the transmission system has four universal joints, two front drive shafts, and a vertical transmission box 10. The design takes into account the relatively low position of the output shaft for the trailer's rearward output. To avoid interference with the mounting positions of the cutter head 2 and the feeder 3, part of the transmission chain is offset upwards. The universal joints are used to prevent motion interference during transmission.
[0115] exist Figure 2 In addition, there is a main drive shaft 16, which includes two half shafts, one of which is connected to the left and one to the right of the transfer case 17 to connect with the driven part on the corresponding side.
[0116] like Figure 2 In the middle, the extended end of the half shaft is provided with a drive sprocket 15. The drive sprocket 15 can be a multi-linked sprocket, so as to form a chain drive mechanism with a relatively large number of driven sprockets through a transmission chain.

Within the concept of this utility model, the above embodiments or different embodiments can be combined without conflict. Although the utility model has been described in detail in the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
