Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural machinery, in particular to a baling device for a round baler. Background Art
[0002] my country has abundant crop straw resources, which are an important renewable resource. However, due to the loose texture of straw, short harvest cycle and scattered distribution, it must be collected, stored and transported mechanized to achieve large-scale and efficient utilization. A round baler is an agricultural machinery device for efficiently collecting straw and forage grass. It picks up straw (forage grass) from the ground and feeds it into a compression chamber, forming round bales under the pressure of rollers, and finally stopping the machine to wrap the net and unload the bales, thereby achieving mechanized collection of straw. Currently, most round balers use fixed-bin steel rollers. However, after the baling chamber is filled with straw, the steel rollers fixed to the inner wall of the baling chamber rotate to squeeze only the outer area of the bale, while the inside of the bale is less squeezed. This results in the bale density being loose inside and tight outside, the overall density being low, and the weight of a single bale being low, which in turn leads to higher costs in collection, transportation, and storage.
[0003] Therefore, how to improve the overall density and density consistency of straw bales is a technical problem that those skilled in the art currently need to solve. Utility Model Content
[0004] The utility model aims to provide a round baler baling device for improving the overall density and density consistency of straw bales.
[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:
[0006] A round baler baling device, characterized by comprising:
[0007] Baling room;
[0008] At least two pressing roller groups are installed in the baling chamber and are arranged in sequence from the center of the baling chamber to the outer circle. Each pressing roller group includes a plurality of pressing rollers whose initial positions are located on the same preset circumference. The diameters of the preset circumferences where the pressing rollers of different pressing roller groups are located are different. At least some of the pressing rollers can move back and forth in the direction from their respective initial positions to the outer circle of the baling chamber, so that some or all of the pressing roller groups are successively surrounded by at least two circles of pressing roller layers with successively increasing diameters. Each circle of the pressing roller layer is used to press the material to be baled to form a round bale of material with a corresponding diameter.
[0009] Compared with the prior art, after the straw and forage enters the baling chamber of the round baler baling device provided by the utility model, each circle of pressing rollers squeezes the straw and forage to form round bales of corresponding diameters during the process of continuously being transported to the baling chamber. Thus, multiple circles of pressing rollers are formed to squeeze the straw and forage layer by layer from the center to the outer circle of the bale, ensuring the tightness of the entire bale from the inside to the outside, thereby improving the density and density consistency of the entire bale, significantly increasing the weight of a single bale, and reducing the costs of collection, transportation, storage and other links.
[0010] Optionally, the round baler baling device further includes an adjustment mechanism fixedly connected to at least some of the pressure rollers to enable at least some of the pressure rollers to reciprocate. Thus, the adjustment mechanism adjusts the positions of at least some of the pressure rollers from their respective initial positions toward the outer circumference of the baling chamber, so that the pressure rollers are arranged to form layers of pressure rollers with successively larger diameters, thereby achieving the round baler baling device's ability to automatically adjust the reciprocating pressure rollers.
[0011] Optionally, in the round baler baling device described above, the adjustment mechanism includes a spring, the movable end of which is connected to at least a portion of the pressure rollers. The spring is configured to apply an elastic force to the reciprocating pressure rollers from the outer ring of the baling chamber to the corresponding initial position. As the diameter of the bale gradually increases, the spring connected to the reciprocating pressure rollers is compressed and elastically deformed. The spring, with its elastic potential energy, reacts against the pressure rollers, causing the pressure rollers to apply a compressive force to the bale. Consequently, each successive layer of pressure rollers, each with a gradually increasing diameter, is able to apply pressure to the bale within each layer under the action of the springs, thereby compressing the bale layer by layer from the inside out. After the bale is extruded and exits the baling chamber, the spring returns to its initial state, causing the reciprocating pressure rollers to return to their initial positions, ready for the next bale preparation. This achieves adaptive adjustment of the reciprocating pressure rollers. The use of springs in the adjustment mechanism offers a simple structure, eliminates the need for complex control, and reduces operational complexity.
[0012] Optionally, in the round baler baling device described above, the adjustment mechanism includes a linear drive mechanism, the drive end of which is connected to at least a portion of the pressure rollers. Thus, the linear drive mechanism is connected to the reciprocating pressure rollers to drive the reciprocating pressure rollers in a direction from their corresponding initial positions to the outer circumference of the baling chamber, thereby adjusting the reciprocating pressure rollers' positions on the two sidewalls of the baling chamber to successively form pressure roller layers of corresponding diameters. The linear drive mechanism may employ a pneumatic cylinder, a hydraulic cylinder, or a linear motor, and possesses highly precise displacement adjustment capabilities.
[0013] Optionally, in the round baler baling device described above, the adjustment mechanism further includes a pressure sensor for detecting pressure applied to at least a portion of the pressure rollers. The linear drive mechanism is electrically connected to the pressure sensor and, under control of the pressure sensor, drives at least a portion of the pressure rollers to move in a direction from the center of the baling chamber toward the outer circumference, such that the pressure rollers form layers of pressure rollers with successively increasing diameters. In this manner, the linear drive mechanism provides power to the reciprocating pressure rollers to compress the straw in the baling chamber. When the pressure sensor detects that the pressure applied to the pressure rollers reaches a preset value, the linear drive mechanism drives the reciprocating pressure rollers to move from a corresponding initial position toward the outer circumference of the baling chamber, adjusting the reciprocating pressure rollers' positions on both sidewalls of the baling chamber to successively form layers of pressure rollers with corresponding diameters. By detecting pressure through the pressure sensor, the adjustment mechanism automatically adjusts the layers of pressure rollers to form layers of varying diameters, saving labor and providing high pressure control accuracy, thereby achieving more consistent bale density.
[0014] Optionally, in the round baler baling device described above, the baling chamber has two opposing side walls, each of which has tracks correspondingly disposed thereon, and the ends of the reciprocating pressure roller are slidably connected to the tracks. Thus, the tracks disposed in the two side walls of the baling chamber enable the reciprocating pressure roller to move from an initial position to the outer circumference of the baling chamber. Strip-shaped through holes can be provided in the side walls of the baling chamber to form the tracks. The strip-shaped through holes have a simple structure and facilitate concealed placement of a spring or drive cylinder, resulting in a compact structure.
[0015] Optionally, in the round baler baling device described above, the pressing roller is mounted on the two side walls of the baling chamber via bearing blocks, and a drive wheel is mounted on at least one end of the pressing roller to drive the pressing roller's rotation. In this manner, the pressing roller is fixed about its own axis to the two side walls of the baling chamber via the bearing blocks, and its rotation is driven by the drive wheel.
[0016] Optionally, the round baler baling device further comprises a conveyor roller disposed at the feed inlet of the baling chamber. The cooperation between the conveyor roller and the baling roller improves the smoothness of the straw entering the baling chamber through the feed inlet, and the smoothness and stability of the rolling of the bale in the baling chamber, thereby further improving the uniformity of the bale compression and the consistency of the density.
[0017] Optionally, in the round baler baling device described above, the baling chamber includes a first half baling chamber and a second half baling chamber, and some of the plurality of press rollers are arranged in the first half baling chamber, while others are arranged in the second half baling chamber. Furthermore, the first half baling chamber and the second half baling chamber can be relatively openable or closable. Thus, after the bale in the inner cavity of the baling chamber is compacted, the first half baling chamber and the second half baling chamber are opened to release the bale from the baling chamber. After the bale is released from the baling chamber, the first half baling chamber and the second half baling chamber are closed and merged to prepare for the next bale compaction cycle. Furthermore, some of the plurality of press rollers are arranged in the first half baling chamber, while others are distributed in the second half baling chamber, so that the press rollers are spaced apart along the circumference of the baling chamber.
[0018] Optionally, in the round baler baling device, the baling chamber further includes a drive device, each of which is connected to the first half baling chamber and the second half baling chamber to drive the first half baling chamber and the second half baling chamber to open or close relative to each other. In this manner, the first half baling chamber and the second half baling chamber are automatically opened and closed relative to each other under the control of the drive device.
[0019] Optionally, in the above-mentioned round baler baling device, at least two of the pressing roller groups include a first pressing roller group, a second pressing roller group, and a third pressing roller group; the at least two layers of pressing rollers include a first pressing roller layer, a second pressing roller layer, and a third pressing roller layer; the first pressing roller group is used to form the first pressing roller layer; the second pressing roller group and the first pressing roller group are used to form the second pressing roller layer; the third pressing roller group, the second pressing roller group, and the first pressing roller group are used to form the third pressing roller layer; the diameters of the first pressing roller layer, the second pressing roller layer, and the third pressing roller layer increase in sequence. In this way, a three-level baling layer is formed, which compresses the bale layer by layer from the center to the outer layer, and finally completes the pressing and forming of the bale.

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.
[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined. "Several" means one or more, unless otherwise specifically defined.
[0040] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0041] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0042] The core of the utility model is to provide a round baler baling device for improving the overall density and consistency of straw bales, thereby increasing the weight of a single straw bale and reducing the costs of collection, transportation, storage and other links.
[0043] like Figure 1 、 Figure 3 and Figure 7As shown, an embodiment of the present invention discloses a round baler baling device comprising a baling chamber 100 and at least two roller groups. Each roller group is installed within the baling chamber 100 and arranged sequentially from the center of the baling chamber 100 to the outer circumference. Each roller group includes multiple rollers 200 initially located on the same predetermined circumference. The diameters of the predetermined circumferences on which the rollers 200 of different roller groups initially reside differ. At least some of the rollers 200 are reciprocally movable from their respective initial positions to the outer circumference of the baling chamber 100, such that some or all of the roller groups sequentially form at least two roller layers of successively increasing diameter. Each roller layer applies a compressive force to the material to be baled, thereby forming a round bale of material having a diameter corresponding to the roller layer.
[0044] It should be noted that the phrase "multiple rollers initially located on the same pre-set circumference" in this application does not require that the pre-set circumference must pass through the center point of each roller. As long as the cross-section of the roller intersects or is tangent to the pre-set circumference, or even if the cross-section of the roller is offset from the pre-set circumference to a certain extent, but the offset does not affect the normal function of the roller, the roller can be considered to be located on the pre-set circumference. Similarly, with reference to the above explanation, for rollers in the same roller layer, it is not required that the center point of each roller be strictly located on the same circumference.
[0045] During the specific operation, after the straw is transported to the baling chamber 100, Figure 3 and Figure 7 As shown, the straw is first squeezed into a round bale of corresponding diameter by the initial pressure rollers 200 in the innermost pressure roller layer (such as the first pressure roller layer) and the smallest diameter. As the straw is continuously transported to the baling chamber 100, the reciprocating pressure rollers 200 are adjusted to move from the initial position toward the outer circle of the baling chamber 100, so that the reciprocating pressure rollers 200 in the innermost pressure roller layer move to the preset circumference of the next adjacent pressure roller layer (such as the second pressure roller layer), as shown in FIG. Figure 4 and Figure 8 As shown, the rollers 200 initially positioned at the first roller layer are adjusted to move outwards to form a second roller layer together with the rollers 200 of the second roller group, so as to form a roller layer with a larger diameter again to continue squeezing the straw to form a round bale with a larger diameter, and so on. Figure 5 and Figure 9As shown, as the straw and forage are continuously transported to the baling chamber 100, the reciprocating pressing rollers 200 previously involved in the squeezing continue to move toward the outer circle, successively forming a pressing roller layer with a larger diameter with other pressing roller groups closer to the outer circle, until forming a pressing roller layer of the outermost circle. In this way, the multiple pressing roller layers arranged in the baling chamber 100 can squeeze the straw and forage layer by layer along the center to the outer circle of the bale, ensuring the tightness of the entire bale from the inside to the outside, thereby improving the density and consistency of the entire bale, significantly increasing the weight of a single bale, and reducing the costs of collection, transportation, storage, and other links.
[0046] In some embodiments, the round baler baling device further includes an adjustment mechanism, which is fixedly connected to at least a portion of the pressure rollers 200 to enable at least a portion of the pressure rollers 200 to reciprocate, i.e., the position of the movable pressure rollers 200 in the direction from their respective initial positions to the outer ring of the baling chamber 100 is adjusted so that the pressure rollers 200 surround to form pressure roller layers with successively larger diameters, thereby realizing the automatic adjustment capability of the round baler baling device for the reciprocating pressure rollers 200. Each pressure roller layer can be automatically and continuously adjusted to form without pausing, thereby improving baling efficiency and saving manpower.
[0047] like Figure 3-Figure 5 As shown, the adjustment mechanism includes a spring 300, the movable end of the spring 300 is connected to the reciprocating pressure roller 200, and the other end of the spring 300 is fixed. In this embodiment, the other end of the spring 300 is fixedly connected to the baling chamber 100. Therefore, during the process of gradually increasing the diameter of the straw bale in the baling chamber 100, the spring 300 connected to the reciprocating pressure roller 200 is squeezed and elastically deformed. The spring 300 with elastic potential energy reacts on the pressure roller 200. The spring 300 applies an elastic force from the outer ring of the baling chamber 100 to the initial position on the reciprocating pressure roller 200, so that the pressure roller 200 applies an extrusion force to the straw and grass entering the baling chamber 100, so that each circle of pressure roller layers with gradually increasing diameters can be compressed under the action of the spring 300. Under these conditions, pressure is applied to the bale within each roller layer, completing the layer-by-layer compression of the bale from the inside out. As straw and forage continue to be fed into the baling chamber 100, the diameter of the round bale gradually increases, forcing the movable roller 200 to move toward the outer ring of the baling chamber 100, forming a roller layer with a larger diameter to compress the straw. Ultimately, after multiple layers of rollers compress the straw layer-by-layer, a bale with high density and uniform consistency is formed. After the straw bale is compressed and leaves the baling chamber 100, the spring 300 returns to its initial state, allowing the reciprocating roller 200 to return to its initial position for the next bale preparation. This achieves a simple overall mechanism while enabling the reciprocating roller 200 to be adaptively adjusted, thereby enhancing the adaptability of the round baler baling device provided by this embodiment. Furthermore, the use of spring 300 as the adjustment mechanism simplifies the structure, eliminates the need for complex control, and reduces operational difficulty.
[0048] like Figure 7-10 As shown, in another specific embodiment, the adjustment mechanism is a linear drive mechanism 400 disposed within the baling chamber 100. The linear drive mechanism 400 is mounted on the side wall of the baling chamber 100 via mounting holes 410. The movable end of the linear drive mechanism 400 is connected to the reciprocating press roller 200 via a press roller connection pair 420. During the bale pressing process, the linear drive mechanism 400 provides power to the reciprocating press roller 200, compressing the hay in the baling chamber 100 and driving the reciprocating press roller 200 from its initial position toward the outer circumference of the baling chamber 100, thereby forming layers of press rollers with increasing diameters. The linear drive mechanism 400 can be implemented using a hydraulic cylinder, a pneumatic cylinder, or a linear motor, thereby providing highly precise displacement adjustment and enhanced control over the movement of the reciprocating press roller 200. Alternatively, those skilled in the art may design other drive methods based on practical needs, which will not be discussed further herein.
[0049] Furthermore, in some embodiments, when the adjustment mechanism is configured as a linear drive mechanism 400, the adjustment mechanism is further provided with a pressure sensor electrically connected to the linear drive mechanism 400. When the pressure sensor detects that the pressure applied to the pressure roller 200 reaches a preset pressure value, the linear drive mechanism 400, under control of the pressure sensor, drives the reciprocating pressure roller 200 from its initial position toward the outer ring of the baling chamber 100, causing the pressure rollers 200 to form layers of pressure rollers with increasing diameters, thereby compressing the straw layer by layer and ultimately forming a bale with high density and uniform consistency. This ensures the precision and online automatic control of the movement of the reciprocating pressure rollers 200. It is understood that the preset pressure value set in each layer of pressure rollers can be the same, or the preset pressure can increase as the diameter of the pressure roller layer increases, further enhancing the overall compactness of the bale. Of course, in the absence of a pressure sensor, the linear drive mechanism 400 can also be controlled by manually determining the degree of compression based on experience.
[0050] like Figure 1 and Figure 2As shown, the baling chamber 100 has two opposing sidewalls, each of which is provided with a track. The two ends of the reciprocating roller 200 are slidably mounted on the track, enabling the reciprocating roller 200 to move within the baling chamber 100. In one specific embodiment, the track is configured as a strip-shaped through-hole 130 formed in the sidewall of the baling chamber 100. The strip-shaped through-hole 130 extends from an initial position to the outer circumference of the baling chamber 100. The ends of the reciprocating roller 200 are slidably connected to the strip-shaped through-hole 130, enabling the reciprocating roller 200 to move from its initial position to the outer circumference of the baling chamber 100. In other embodiments, grooves or protrusions may be used as the track. In addition, the spring 300 or the linear drive mechanism 400 for driving the reciprocating pressure roller 200 can be installed in the strip-shaped through-hole 130 to reduce the interference of the rolling bale in the baling chamber 100 on the spring 300 or the linear drive mechanism 400. At the same time, the strip-shaped through-hole 130 has a simple structure and facilitates the concealed arrangement of the spring 300 or the linear drive mechanism 400, resulting in a compact structure. Alternatively, in other embodiments, the two side walls of the baling chamber 100 are provided with a guide rail and slider mechanism, the reciprocating pressure roller 200 is connected to the slider, and the guide rail is fixed to the side wall of the baling chamber 100, so that the reciprocating pressure roller 200 is movably connected to the side wall of the baling chamber 100 via the guide rail and slider mechanism.
[0051] like Figure 6 As shown, the ends of the pressing roller 200 are mounted on the two side walls of the baling chamber 100 via bearing blocks 210, respectively, to enable the pressing roller 200 to rotate about its own axis. The reciprocating pressing roller 200 is slidably disposed within the strip-shaped through-hole 130 via the bearing blocks 210, enabling the reciprocating pressing roller 200 to move along the side wall of the baling chamber 100. A drive wheel 220 is mounted on one end of the pressing roller 200 extending out of the baling chamber 100 to drive the pressing roller 200 to rotate. In this embodiment, the drive wheel is a sprocket, which cooperates with a chain to drive the rotation of the pressing roller 200. Chain drive is highly efficient, low-cost, and adaptable to harsh environments such as dusty and humid environments, making it particularly suitable for bale pressing. Alternatively, those skilled in the art may design other transmission structures to drive the pressing roller 200, such as gear drives or belt drives, based on actual needs. This description will not be repeated here.
[0052] At the same time, the baling device provided in this embodiment also includes a conveyor roller 500, which is disposed at the feed inlet 150 of the baling chamber 100. The conveyor roller 500 can be installed on the side wall of the baling chamber 100, so that the conveyor roller 500 and the pressure roller 200 cooperate to form a pressure roller layer. The cooperation between the conveyor roller 500 and the pressure roller 200 improves the smoothness of straw entering the baling chamber 100 through the feed inlet 150, and improves the smoothness and stability of the rolling of the straw bale in the baling chamber 100, thereby further improving the uniformity of the straw compression and the consistency of the density.
[0053] like Figure 1 and Figure 7 As shown, the conveying rollers 500 include a front conveying roller 510, a middle conveying roller 520 and a rear conveying roller 530 that are arranged at intervals along the circumferential direction of the baling chamber 100. The front conveying rollers 510, the middle conveying rollers 520 and the rear conveying rollers 530 are arranged in sequence in a direction away from the feed inlet 150. By arranging the conveying rollers 500 at multiple positions such as the front conveying rollers 510, the middle conveying rollers 520 and the rear conveying rollers 530, and cooperating with the pressure rollers 200 of the pressure roller layer, not only the bale conveying capacity of the conveying rollers 500 is further improved, but also the rotation of the bale in the baling chamber 100 is made smoother and more stable, the uniformity of the compression of the bale is improved, and the consistency of the density and overall density of the bale is further promoted.
[0054] like Figure 2 As shown, the baling chamber 100 includes a first half-baling chamber 110 and a second half-baling chamber 120. The first half-baling chamber 110 and the second half-baling chamber 120 can be relatively opened or closed. A portion of the plurality of pressing rollers 200 are arranged in the first half-baling chamber 110, while the other portion are distributed in the second half-baling chamber 120, so that the pressing rollers 200 are spaced apart along the circumference of the baling chamber 100. Specifically, the first half-baling chamber 110 and the second half-baling chamber 120 are hingedly connected. After the bale in the inner cavity of the baling chamber 100 is compressed, the hinged first half-baling chamber 110 and the second half-baling chamber 120 are rotated open to complete the release of the bale from the baling chamber 100. After the bale is released from the baling chamber 100, the first half-baling chamber 110 and the second half-baling chamber 120 are rotated again to close and merge, preparing for the next bale compression cycle. Of course, the first half baling chamber 110 and the second half baling chamber 120 can also be relatively disassembled and assembled to achieve relative opening or closing of the first half baling chamber 110 and the second half baling chamber 120 .
[0055] like Figure 1 and Figure 2As shown, in a specific embodiment, the baling chamber 100 further includes a drive device 140 located on the outer wall of the baling chamber 100 housing. The drive device 140 is respectively connected to the first and second baling chamber halves 110, 120 to drive the first and second baling chamber halves 110, 120 to open or close relative to each other. When the first and second baling chamber halves 110, 120 are hinged, the drive device 140 can be used to drive the first and second baling chamber halves 110, 120 to rotate relative to each other, thereby opening and closing the first and second baling chamber halves 110, 120. When the first and second baling chamber halves 110, 120 are detachable and reassembleable, at least two drive devices 140 can be used to drive the first and second baling chamber halves 110, 120 to open and close relative to each other. The driving device 140 can be hydraulic, pneumatic, or electric. Those skilled in the art can design it according to actual needs, and they will not be listed one by one in this article.
[0056] like Figure 4 、 Figure 5 and Figure 6 The baling chamber 100 shown in the figure has a spring 300 as the adjustment mechanism and is provided with three layers of pressure rollers. Figure 7 、 Figure 8 and Figure 9 The baling chamber 100 shown in the figure has an adjustment mechanism using a linear drive mechanism 400 and is provided with three circles of pressing roller layers, wherein there are three groups of pressing roller groups, including a first pressing roller group, a second pressing roller group and a third pressing roller group, and the three circles of pressing roller layers are respectively a first circle of pressing roller layer, a second circle of pressing roller layer and a third circle of pressing roller layer. The first pressing roller group is used to form a first circle of pressing roller layer, the second pressing roller group and the first pressing roller group are used to form a second circle of pressing roller layer together, and the third pressing roller group, the second pressing roller group and the first pressing roller group are used to form a third circle of pressing roller layer together. The diameters of the first circle of pressing roller layer, the second circle of pressing roller layer and the third circle of pressing roller layer increase successively.
[0057] For example, the pressing rollers 01, 02, 03, 04, 05 and 06 in the baling chamber 100 are the first pressing roller group, and all of them can be reciprocating pressing rollers 200. Of course, some of them can also be reciprocating pressing rollers, such as Figure 3 and Figure 7As shown, the initial positions of the pressure rollers 200 of the first pressure roller group are located on the same preset circumference of the innermost layer, and the pressure rollers 200 of the first pressure roller group cooperate with the front conveying roller 510, the middle conveying roller 520 and the rear conveying roller 530 to form a first circle of pressure rollers; the pressure rollers 07, 08, 09 and 10 located in the middle layer of the baling chamber 100 are the second pressure roller group, among which the pressure rollers 08, 09 and 10 can be reciprocating pressure rollers 200, and the pressure roller 07 is a fixed and immovable pressure roller 200. The initial positions of the pressure rollers 200 of the second pressure roller group are located on the same preset circumference of the middle layer; the pressure rollers 11, 12, 13 and 14 located in the outermost circle of the baling chamber 100 are the third pressure roller group, and the pressure rollers 200 in the third pressure roller group can all be fixed and immovable pressure rollers 200. The pressure rollers 200 of the third pressure roller group are always located on the same preset circumference of the outermost circle.
[0058] like Figure 3 and Figure 4 As shown, in the case where the adjustment mechanism adopts a spring 300, the reciprocating pressing rollers 01, 02, 03, 04, 05, 06, 08, 09 and 10 are all installed in the sliding hole of the baling chamber 100 through the spring 300. Figure 7 and Figure 8 As shown, the reciprocating pressure rollers 01 , 02 , 03 , 04 , 05 , 06 , 08 , 09 and 10 are all connected to the driving end of the linear drive mechanism 400 .
[0059] When working, Figure 3 and Figure 7 As shown, straw feed continuously enters the baling chamber 100 through the feed port, gradually filling the first circle of rollers formed by the first roller group and the conveying rollers, and the straw feed is squeezed by the first circle of rollers. Figure 4 and Figure 8 As shown, as the straw and forage are continuously transported to the baling chamber 100, the first pressing roller group moves toward the outer circle of the baling chamber 100, and its diameter gradually increases. When the pressing rollers 200 of the first pressing roller group move from their initial positions to the preset circumference of the second pressing roller group, pressing rollers 01, 02, 03, 04, 05, 06, 07, 08, 09, and 10 cooperate with the front conveying roller 510, the middle conveying roller 520, and the rear conveying roller 530 to form a second circle of pressing rollers, which continue to squeeze the straw in the baling chamber 100. Afterwards, as shown in FIG. Figure 5 and Figure 9As shown, the straw and forage continue to be transported to the baling chamber 100, and the diameter of the bale continues to increase, so that the first pressing roller group and the second pressing roller group continue to move toward the outermost circle of the baling chamber 100, and the pressing rollers 01, 02, 03, 04, 05, 06, 07, 08, 09 and 10 are located on the same preset circumference as the pressing rollers 11, 12, 13 and 14, and at this time cooperate with the front conveying roller 510, the middle conveying roller 520 and the rear conveying roller 530 to form a third circle of pressing rollers, so that the straw and forage in the baling chamber 100 is finally pressed and formed into a bale after being squeezed layer by layer.
[0060] Of course, the number of pressing roller groups can also be two, four, etc. The number of pressing rollers 200 in each pressing roller group and the number of reciprocating pressing rollers 200 are not limited to the cases listed in the above embodiments, and can also be reasonably set according to the actual size and weight requirements of the bale.
