[0002] In related technologies, the baling chamber of a round baler is equipped with multiple pressure rollers to compress the straw entering the baling chamber into bales. Because there are gaps between adjacent pressure rollers, some straw easily leaks out through these gaps and cannot be effectively collected into the bales, reducing the number of bales. Furthermore, the leaked straw requires additional manual cleaning, further reducing the straw collection efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a baler that can recover the straw that leaks out from the gap between the pressure rollers and put it back into the baling chamber, thereby increasing the number of bales and the collection efficiency.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The baling machine provided in one embodiment of this application includes a frame 1, a first chamber 2, a second chamber 3, multiple pressure rollers (not shown in the figure), a first conveying mechanism 5, and a second conveying mechanism 6. The frame 1 serves as the mounting carrier for the first chamber 2, the second chamber 3, the multiple pressure rollers, the first conveying mechanism 5, and the second conveying mechanism 6. Both the first chamber 2 and the second chamber 3 are connected to the frame 1 and are spaced apart. The first chamber 2 has a feed inlet 21. The second chamber 3 communicates internally with the first chamber 2, and both the first chamber 2 and the second chamber 3 contain multiple pressure rollers. The multiple pressure rollers, the first chamber 2, and the second chamber 3 together form a baling chamber 4.

[0040] It should be noted that since the final bale formed in the baling chamber 4 of the baler is cylindrical, multiple pressing rollers are arranged around the inner walls of the first chamber 2 and the second chamber 3 to match the shape of the bale. When the baler is working, the straw enters the baling chamber 4 from the first feed inlet 21 and is compacted to form a bale. When the diameter of the bale reaches the preset size, the bale rolls out of the baling chamber 4. It should be noted that in this embodiment, the second chamber 3 can rotate relative to the first chamber 2. When the baler is about to start the baling operation, the first chamber 2 and the second chamber 3 are connected, and the baling chamber 4 is closed. When the bale reaches the specified radial size or weight in the baling chamber 4, the second chamber 3 rotates relative to the first chamber 2, so that the bale rolls out from the bottom of the baling chamber 4. The frame 1 is provided with a drive structure for driving the second chamber 3 to rotate. Therefore, the second chamber 3 can rotate relative to the first chamber 2. This drive structure can be a motor or a hydraulic cylinder, etc.

[0041] See Figure 4Because hay can leak out from the gaps between the corresponding pressing rollers in the first chamber 2 or the second chamber 3 within the baling chamber 4, a first conveying mechanism 5 and a second conveying mechanism 6 are provided, corresponding one-to-one with the first chamber 2 and the second chamber 3. The first conveying mechanism 5 is located close to the first chamber 2 and below the pressing rollers, with its outlet end connected to the inlet 21. When hay leaks out from the gaps between the corresponding pressing rollers in the first chamber 2, it can directly re-enter the baling chamber 4 through the inlet 21 via the first conveying mechanism 5 and be compacted into bales. To shorten the conveying path of the second conveying mechanism 6, it is located close to the second chamber 3 and below the pressing rollers, with its outlet end connected to the inlet end of the first conveying mechanism 5. When the hay leaks out from the gap between the corresponding pressing rollers in the second bin 3, it is sequentially conveyed by the second conveying mechanism 6 to the first conveying mechanism 5 and re-enters the bundling chamber 4 through the feed inlet 21 to be compacted into bales, thereby increasing the number of bales and collection efficiency.

[0042] Furthermore, such as Figure 4 and Figure 5 As shown, since the first conveying mechanism 5 is arranged entirely below the feed inlet 21, there is a certain height difference between its discharge end and the feed inlet 21, making it difficult for the straw to smoothly enter the baling chamber 4 under its own weight after being conveyed to the end of the first conveying mechanism 5. Therefore, in one embodiment, the baler also includes a recovery roller 7. The recovery roller 7 is installed above the first conveying mechanism 5 and is located near the feed inlet 21. The recovery roller 7 and the frame 1 are rotatably supported by a rotating connection structure such as bearings. Multiple teeth 71 are evenly distributed on the outer periphery of the recovery roller 7. These teeth 71 extend radially along the recovery roller 7 and have a certain rigidity and elasticity, which can effectively grab and lift the straw on the first conveying mechanism 5 during the rotation of the recovery roller 7. The recovery roller 7 is driven by an independent drive device (such as a motor) and can rotate stably relative to the frame 1. When the first conveying mechanism 5 conveys the hay to its discharge end, the rotating recycling roller 7 conveys the hay to the feed inlet 21 through the toothed teeth 71, thereby significantly improving the continuity and reliability of feeding, avoiding hay accumulation or backflow, and facilitating efficient and stable bale-making operations.

[0043] Furthermore, such as Figure 5As shown, to facilitate the conveying of hay to the feed inlet 21 by the recovery roller 7, and to prevent hay from leaking out from the gap between the recovery roller 7 and the first conveying mechanism 5, in some embodiments, the baler also includes an arc-shaped baffle 52. The arc-shaped baffle 52 surrounds the recovery roller 7, forming a guide channel between the arc-shaped baffle 52 and the recovery roller 7. One end of the arc-shaped baffle 52 is connected to the feed inlet 21, and the other end is connected to the discharge end of the first conveying mechanism 5. As shown, the arc-shaped baffle 52 is located between the recovery roller 7 and the first conveying mechanism 5. The hay on the first conveying mechanism 5 is guided and conveyed to the feed inlet 21 by the arc-shaped baffle 52. The teeth 71 of the recovery roller 7 lift the hay to the inside of the baffle. The curved structure of the arc-shaped baffle 52 guides the hay to slide smoothly along the inner wall towards the feed inlet 21, effectively preventing hay from scattering out from the gap between the recovery roller 7 and the first conveying mechanism 5, avoiding hay leakage, and improving hay recovery efficiency.

[0044] In some embodiments, when the discharge end of the first conveying mechanism 5 is parallel to or partially located at the inlet 21, the forage on the first conveying mechanism 5 can be directly conveyed to the inlet 21 without the need for the recovery roller 7.

[0045] Furthermore, such as Figure 5 As shown, to simplify the structure of the first conveying mechanism 5, a conveyor belt can be used. In some embodiments, the conveyor belt includes at least a drive motor, a drive roller, a driven roller, and a belt. The drive motor is fixedly connected to the frame 1, and its output end drives the drive roller to rotate. The driven roller is rotatably connected to the frame 1. The belt is sleeved around the drive roller and the driven roller. When the drive motor drives the drive roller to rotate, the belt is in a tensioned state and can drive the driven roller to rotate synchronously, thereby realizing the conveying function of the first conveying mechanism 5. To reduce the manufacturing difficulty of the first conveying mechanism 5, standard parts can be directly purchased, so its specific structure will not be described in detail. During the process of the belt driving the grass to move, in order to prevent the grass from leaking out from both sides of the first conveying mechanism 5, in one embodiment, baffle plates 51 are also provided on both sides of the first conveying mechanism 5. The baffle plates 51 and the side wall of the belt are provided with a gap, which is conducive to the smooth passage of grass and avoids the baffle plates 51 from contacting the belt and obstructing the conveying. When the hay is conveyed by the belt, the baffle plate 51 blocks the hay to gather in the central area of ​​the belt, preventing the hay from overflowing from both sides due to belt vibration or tilting, thus improving the stability of the hay recycling process.

[0046] Furthermore, to simplify the structure of the second conveying mechanism 6, it can also be a conveyor belt; its specific structure will not be described in detail. For example... Figure 5 and Figure 6As shown, in one embodiment, the discharge end of the second conveying mechanism 6 is inclined towards the inlet end of the first conveying mechanism 5, and the discharge end of the second conveying mechanism 6 is located directly above the inlet end of the first conveying mechanism 5. This allows the hay to slide down to the inlet 21 of the first conveying mechanism 5 by its own gravity without additional power after leaving the second conveying mechanism 6, thus reducing energy consumption. The inclination angle ranges from 10° to 30°, which facilitates the rapid transport of the hay to the first conveying mechanism 5 by its own gravity, reducing the time it takes for the hay to pass through the second conveying mechanism 6 and the first conveying mechanism 5 sequentially before entering the inlet 21, thereby improving the hay bale formation efficiency.

[0047] Furthermore, such as Figure 3 , Figure 7 As shown, in some embodiments, to facilitate the picking up of hay on the ground, the baler also includes a crushing and picking platform 8. The crushing and picking platform 8 is connected to the frame 1, and its length direction is perpendicular to the length direction of the frame 1. The length of the crushing and picking platform 8 is affected by transportation factors and should not be too long. Therefore, in related technologies, the length of the crushing and picking platform 8 is generally 0.1m, which greatly limits the picking efficiency of the baler. Therefore, in this application, to avoid the crushing and picking platform 8 being too long and difficult to transport, and to improve the picking efficiency of the crushing and picking platform 8, as shown... Figure 8 and Figure 9 As shown, in one embodiment, the crushing and picking platform 8 includes a support 81, two drive mechanisms 82 and two crushing and picking units 83. The two drive mechanisms 82 and the two crushing and picking units 83 are located on both sides of the support 81 in a one-to-one correspondence. The fixed end of the drive mechanism 82 is rotatably connected to the support 81, and the output end of the drive mechanism 82 is rotatably connected to the crushing and picking unit 83, and can drive the crushing and picking unit 83 to rotate relative to the support 81 by a preset angle.

[0048] When the baler is transporting goods, the two sets of drive mechanisms 82 drive the two crushing and picking units 83 to rotate and fold in opposite directions, as shown in the figure. Figure 7 and Figure 9 As shown, from Figures 8 to 9 During the process, the two crushing and picking units 83 rotate from a horizontal position to a vertical position, as shown in the image. Figure 7 As shown, the width of the baler is reduced, which facilitates transportation. When the baler needs to work, from... Figures 9 to 8 During the process, the two crushing and picking units 83 rotate from a vertical position to a horizontal position, as shown in the image. Figure 3As shown, at this time, the picking length of the crushing and picking platform 8 is extended, reaching 3.5m, which greatly improves the picking efficiency of the crushing and picking platform 8. It should be noted that the preset angle of the crushing and picking platform 8 is less than or equal to 90°, and can be adaptively adjusted according to the actual production and transportation needs of the baler. In order to simplify the rotation structure between the drive mechanism 82 and the crushing and picking unit 83 and the support 81, the drive mechanism 82 is hinged to the crushing and picking unit 83 and the support 81.

[0049] like Figure 9 As shown, to simplify the structure of the crushing and picking unit 83, in one embodiment, the crushing and picking unit 83 includes a picking bin 831 and a picking shaft 832. The picking bin 831 is hinged to the output end of the drive mechanism 82. The picking bin 831 has a discharge port facing the first bin body 2, which communicates with the inlet 21. The picking shaft 832 is located inside the picking bin 831, and picking claws 833 are provided circumferentially on the picking shaft 832. It should be noted that the picking bin 831 is provided with a drive structure for rotating the picking shaft 832. The drive structure drives the picking shaft 832 to rotate, which in turn drives the picking claws 833 to rotate and pick up the hay, conveying the hay in the picking bin 831 from the discharge port to the inlet 21. The hay then enters the baling chamber 4 to form hay bales. Further, to simplify the structure of the drive mechanism 82, in one embodiment, as shown in the figure, the drive mechanism 82 is a hydraulic cylinder.

[0050] Furthermore, such as Figure 2 As shown, in order to facilitate the movement of the baler, the baler also includes tires 9 and a towing frame 10. The tires 9 are connected to the frame 1, and the towing frame 10 is located at the end of the frame 1 away from the first compartment 2. The towing frame 10 is equipped with a standard towing interface, which can be quickly connected to an external towing mechanism (such as the towing rod of a tractor) to achieve reliable power transmission, so that the towing mechanism can drive the baler to a designated area to bale and collect hay, thereby improving the mobility and operational flexibility of the baler.

[0051] Furthermore, to facilitate the transport of straw from the crushing and picking unit 83 to the baling chamber 4 and improve the feeding efficiency of the baling chamber 4, the baler also includes at least one feeding mechanism 11, located between the discharge port and the inlet 21. As shown in the figure, there can be two feeding mechanisms 11, spaced apart between the discharge port and the inlet 21, and the number of feeding mechanisms 11 can be adjusted adaptively according to actual feeding needs. In one embodiment, to simplify the overall structure of the feeding mechanism 11, the feeding mechanism 11 includes a feeding shaft 111 and multiple feeding teeth 112, with multiple feeding teeth 112 arranged circumferentially on the feeding shaft 111. It should be noted that the frame 1 is provided with a drive structure corresponding to the feeding shaft 111, used to drive the feeding shaft 111 to rotate, thereby driving the feeding teeth 112 to transport the straw from the crushing and picking unit 83 to the baling chamber 4 through the inlet 21. The drive structure can use a motor and a reducer together to precisely control the rotational speed of the feed shaft 111.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
