Description

Technical Field

[0001] This utility model generally relates to the field of agricultural machinery and equipment technology. More specifically, this utility model relates to an automatic chaff picker and chopper. Furthermore, this utility model also relates to a hay bale machine. Background Technology

[0002] With the modernization of agricultural equipment, combine harvesters have become the main tool for harvesting crops, and the harvested straw is usually scattered in the fields. However, traditional methods of disposal, such as burning straw, not only cause serious air pollution but also may cause fires, posing a great threat to the environment and the safety of farmers' lives and property. Therefore, in order to make full use of straw energy, reduce air pollution, and protect the safety of farmers' lives and property, people have begun to explore rational ways to utilize straw, such as straw power generation, straw carbonization, straw fertilization, substrate production, and feed processing.

[0003] In the processing of straw into feed, automatic straw-collecting and chopping machines are an effective tool, capable of processing straw into feed suitable for animals. This machine mainly consists of a picking device, a conveying device, and a chopping cutter. The picking device includes a roller and several picking teeth extending radially along the roller. During operation, the picking device, in conjunction with other components, controls the rotation of the roller so that the picking teeth can pick up the straw and place it onto the conveying device. The straw is then transported by the conveying device to the chopping cutter for cutting and processing, ultimately producing feed. However, existing automatic straw-collecting and chopping machines (CN216087724U) suffer from insufficient stability in their transmission system. Specifically, the gear and chain meshing structure of some picking components is poorly designed, easily leading to problems such as chain and gear skipping, tooth skipping during transmission, or loosening due to vibration. Especially when the equipment is running at high speed to improve work efficiency, unstable transmission will directly lead to uneven movement of the picking parts, high failure rate and low efficiency, which will aggravate material blockage and even cause accelerated wear of transmission parts, shortening the service life of the equipment.

[0004] In view of this, there is an urgent need to provide an automatic chaff picker and chaff block machine so that the picking device can guide the chain to move smoothly on the gears, reduce chain skipping and vibration during transmission, and thus improve the working efficiency of the automatic chaff picker.

[0030] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1-4The present invention provides an automatic chaff-picking and chaff-cutting machine 100, which includes a picking mechanism 101, a conveying mechanism 102, and a chaff-cutting mechanism 103 connected in sequence. The picking mechanism 101 includes: a picker 1012, which includes a rotating shaft and a plurality of picking teeth 1014 disposed on the outer surface of the rotating shaft; the picker 1012 is used to pick up materials onto a support plate 1011; and a vertical tooth type picking assembly, which is used to pick up materials on the support plate 1011 onto the conveying mechanism 103. The conveying mechanism 102 is used for the vertical toothed pickup assembly, which includes a first end plate 1015 and a second end plate 1016 disposed opposite to each other, a power input shaft 1017 and N vertical toothed shafts 1018 fixedly connected between the first end plate 1015 and the second end plate 1016, and the vertical toothed shafts 1018 are provided with a plurality of pickup teeth; a constant chain gear 1020 and a main planetary chain gear 1021 are provided on the outer side of the first end plate 1015, and N sets of secondary planetary chain gears are provided on the outer side of the second end plate 1016. The system includes a sprocket 1022 and a pressure wheel 1023; the main planetary sprocket 1021 meshes with the constant sprocket 1020 to achieve reverse rotation, and transmits the motion to the secondary planetary sprocket 1022 through the truncated tooth shaft 1018, so that all the picking teeth maintain a vertically downward posture during the revolution, wherein the included angle of the chain 1029 on each secondary planetary sprocket 1022 is any angle between 15 and 45 degrees; and at least two blocking members 1024, each blocking member 1024 including a blocking part 1025 and an extension part 1026, wherein the blocking part 1025 is an arc-shaped part disposed between the support plate 1011 and the truncated tooth picking assembly, and its two ends are respectively connected to the front end and rear end brackets of the truncated tooth picking assembly; the extension part 1026 is fixed on the blocking part 1025 and has a preset angle between it and the blocking part 1025, and the extension part 1026 is located above the conveying mechanism 102.

[0032] Specifically, the picking mechanism 101 in this solution includes a support plate 1011, a picker 1012 connected to the support plate 1011, and a vertical toothed picking assembly disposed above the support plate 1011. More specifically, the support plate 1011 has an arc-shaped upper surface, with a first end in the height direction connected to the conveying mechanism 102 and a second end in the height direction connected to the picker 1012, wherein the position of the first end is higher than the position of the second end. The picker 1012 includes a cylindrical rotating shaft 1013 connected to the second end of the support plate 1011, and a plurality of picking teeth 1014 with a preset extension length disposed circumferentially along the rotating shaft 1013. The picking teeth 1014 extend along the tangential direction of the rotating shaft, and in this solution, the rotating shaft rotates toward the support plate 1011, while the extension direction of the picking teeth 1014 is opposite to the tangential direction of the rotation of the rotating shaft.

[0033] The serrated pick-up assembly is the core transfer component of the pick-up mechanism 101 of the automatic chaff picker 100. It is connected to the drive device and uses precise motion control to stably pick up the straw material on the support plate 1011 and transfer it to the conveying mechanism 102, ensuring the subsequent material delivery to the chaff cutting mechanism 103 and preventing material accumulation or residue on the support plate 1011. Specifically, the serrated pick-up assembly includes a first end plate 1015 and a second end plate 1016 arranged opposite to each other, a power input shaft 1017 and N serrated shafts 1018 arranged between them, and multiple pick-up grates evenly distributed on each serrated shaft 1018. In addition, a constant chain gear 1020 and a main planetary chain gear 1021 are mounted on the outer side of the first end plate 1015, while N sets of secondary planetary chain gears 1022 are correspondingly arranged on the outer side of the second end plate 1016. Each set of secondary planetary chain gears 1022 corresponds to one truncated gear shaft 1018, and the secondary planetary chain gears 1022 and the pressure wheel 1023 are staggered. The constant chain gear 1020 is in a fixed state, and the main planetary chain gear 1021 is fixedly connected to one end of the truncated gear shaft 1018. When the power input shaft 1017 drives the first end plate 1015, the second end plate 1016, and the overall assembly to revolve around the power input shaft 1017, the main planetary chain gear 1021, due to meshing with the fixed constant chain gear 1020, will generate a reverse rotational motion opposite to the direction of revolution. This reverse rotation is transmitted through the truncated gear shaft 1018 to the corresponding secondary planetary sprocket 1022 on the outer side of the second end plate 1016. Simultaneously, the clamping wheel 1023, through its engagement with the chain 1029, prevents slippage of the chain 1029 during transmission, ensuring that the reverse rotation motion is evenly transmitted to all secondary planetary sprockets 1022, ultimately driving all truncated gear shafts 1018 to rotate synchronously in the opposite direction. Furthermore, the included angle of the chain 1029 on each secondary planetary sprocket 1022 is precisely designed to be any angle between 15 and 45 degrees. This angle range is crucial for ensuring stable transmission of the chain 1029. The solution in this application, by limiting the included angle of the chain on each secondary planetary sprocket to between 15 and 45 degrees, allows for a tighter and more precise meshing between the chain and the teeth of the secondary planetary sprocket, thereby increasing the number of meshing teeth and effectively preventing tooth skipping during transmission.

[0034] Those skilled in the art will understand that in the transmission engagement between the gear and the chain 1029, a suitable included angle allows the chain 1029 and the tooth grooves of the secondary planetary gear 1022 to achieve a tighter and more precise meshing, maximizing the number of meshing teeth. This avoids problems such as insufficient teeth on the chain 1029 and gear meshing wheel due to an excessively large included angle, leading to easy chain slippage, or excessive compression and accelerated wear of the chain 1029 due to an excessively small included angle. In other words, this angle range can guide the chain 1029 to move along a smoother trajectory on the secondary planetary gear 1022, significantly reducing tooth skipping and vibration of the chain 1029 during transmission, and reducing additional noise and component wear caused by transmission instability.

[0035] To further optimize the picking process and prevent material backflow or scattering during picking and conveying, the picking mechanism 101 is also equipped with at least two blocking components 1024. Each blocking component 1024 consists of a blocking part 1025 and an extension part 1026. The blocking part 1025 is an arc-shaped component, disposed between the support plate 1011 and the vertical tooth picking assembly, and is staggered with the picking teeth. The two ends of the blocking part 1025 are connected to the front and rear supports of the vertical tooth picking assembly, respectively, serving to fix and support it. The extension part 1026 is fixed to the blocking part 1025, forming a preset angle with the blocking part 1025, and is located above the conveying mechanism 102. When the material is picked up and conveyed to the conveying mechanism 102, the extension part 1026 can play a certain guiding and blocking role, ensuring that the material can smoothly transition from the picking mechanism 101 to the conveying mechanism 102, thereby improving the stability and reliability of the entire picking process.

[0036] In this application, by setting a blocking element 1024, the material can be transferred more smoothly from the picker 1012 to the conveying mechanism 102, effectively preventing the material from flowing back or scattering during the picking and conveying process, significantly reducing the loss of material during the conveying process, and improving the efficiency and reliability of the entire picking and conveying process.

[0037] The automatic straw-collecting and chaff-cutting machine 100 also includes a conveying mechanism 102, which is responsible for transporting the straw collected by the collector 1012 to the chaff-cutting mechanism 103. Specifically, the conveying mechanism 102 mainly consists of a conveyor belt 1032 and multiple spiral assemblies to ensure smooth transport of the straw. The conveyor belt 1032 is designed with a preset extension length, providing a continuous conveying surface for carrying and moving the straw. Above the conveying surface of the conveyor belt 1032, several spiral assemblies are evenly spaced, arranged along the length of the conveyor belt 1032 to ensure uniform distribution of the straw during the conveying process. Each spiral assembly consists of a rotating shaft 1030 and spiral blades 1031, which extend along the width of the conveyor belt 1032, allowing the spiral assembly to evenly distribute the straw along the width of the conveyor belt 1032 when rotating. This design not only improves conveying efficiency but also helps to avoid the accumulation and blockage of straw during the conveying process, ensuring that the straw can be evenly and continuously transported to the chaff-cutting mechanism 103 for cutting. Through this efficient conveying mechanism 102 design, the automatic straw-collecting and chaff-cutting machine 100 can achieve rapid and uniform conveying of straw, thereby improving overall work efficiency.

[0038] In one specific implementation, mounting holes are provided on the front and rear supports of the toothed pickup assembly. The blocking part 1025 is inserted into the mounting hole and limited in the mounting hole by the first limiting part provided at its end. The blocking part 1025 is provided with a second limiting part at a first preset distance from the first limiting part, and an elastic member 1027 is provided between the first limiting part and the second limiting part.

[0039] In this application, mounting holes are provided on both the front and rear supports of the toothed pickup assembly. These mounting holes are specifically used to assemble the blocking part 1025 of the blocking member 1024, forming a stable connection structure between the blocking member 1024 and the toothed pickup assembly. Specifically, the blocking part 1025 is inserted into the mounting hole, and initial fixation is achieved by a first limiting part at the end of the blocking part 1025. The first limiting part can directly engage with the outside of the mounting hole, preventing the blocking part 1025 from completely dislodging from the mounting hole and ensuring that the blocking part 1025 remains in the preset assembly position during operation. Furthermore, a second limiting part is provided on the blocking part 1025 at a first preset distance from the first limiting part, and an elastic component 1027, such as a spring, is assembled between the first and second limiting parts.

[0040] In use, when the amount of material transferred by the toothed pickup assembly temporarily increases, or when a small amount of impurities in the material cause the blocking part 1025 to be subjected to a large impact force, the elastic component 1027 can buffer the pressure through its own deformation, allowing the blocking part 1025 to move slightly in a preset direction within the mounting hole, avoiding hard contact that could damage the blocking part 1025 or the bracket; and when the impact force disappears, the elastic component 1027 can push the blocking part 1025 back to its original position by its own elastic restoring force, ensuring that it always maintains the limiting effect on the material, which not only ensures the stable function of the blocking component 1024, but also improves the impact resistance of the overall structure of the toothed pickup assembly, providing reliable support for the stable transfer of materials.

[0041] Those skilled in the art will understand that the protection scheme of this application is not limited to the embodiment in which mounting holes are provided on both the front and rear supports of the toothed pickup assembly. In fact, a scheme in which mounting holes are provided only on the front or rear supports of the toothed pickup assembly, with one end of the blocking part 1025 fixedly connected to the support and the other end connected to the support via a movable connection, also falls within the protection scope of this application. In this scheme, one end of the blocking part 1025 is provided with an elastic member 1027, while the other end does not have an elastic member 1027. In this design, the elastic member 1027 can provide a certain buffering effect, helping to reduce impact force when material passes through, and ensuring the stability and reliability of the entire pickup and conveying process.

[0042] In one specific implementation, the mounting hole has a preset extension length, wherein the length direction is the same as the extension direction of the front end of the toothed pickup assembly towards the rear end.

[0043] In this design, the mounting hole is designed with a preset extension length, the direction of which is consistent with the extension direction of the toothed pickup assembly from the front end to the rear end; that is, the mounting hole is horizontal and perpendicular to the power input shaft 1017. This design allows the blocking part 1025 to be adjusted in position within a certain range along this extension direction, thereby better adapting to different working conditions and material characteristics, and improving the flexibility and adaptability of the equipment.

[0044] In one specific implementation, in a free state, one end of the elastic member 1027 abuts against the second limiting part, and the other end has a second preset distance from the mounting hole.

[0045] In the present application, when the elastic member 1027 is in a free state, one end of it is in close contact with the second limiting part, while the other end maintains a certain distance from the mounting hole. This distance is defined as the second preset distance. When subjected to external force, the elastic member 1027 can extend or deform within the second preset distance and its elastic range to adapt to different working conditions and material properties.

[0046] In one specific implementation, both the first end plate 1015 and the second end plate 1016 are circular components with a diameter of 80-100 cm, and the outer side of the second end plate 1016 is provided with 5 sets of secondary planetary sprockets 1022. Both the first end plate 1015 and the second end plate 1016 are provided with multiple first hollow portions 1028.

[0047] In this application, both the first end plate 1015 and the second end plate 1016 are circular with a diameter between 80 and 100 centimeters. This size design aims to ensure sufficient space on the end plates for mounting the constant sprocket 1020 and the main planetary sprocket 1021, etc. The outer side of the second end plate 1016 is provided with 5 sets of secondary planetary sprockets 1022 and 5 sets of pressure rollers 1023. By adjusting the position of the pressure rollers 1023, the included angle of the chain 1029 on each secondary planetary sprocket 1022 is maintained at 19 degrees, thereby guiding the chain 1029 to move on the secondary planetary sprockets 1022 with a smoother trajectory, significantly reducing tooth skipping and vibration of the chain 1029 during transmission.

[0048] In addition, both the first end plate 1015 and the second end plate 1016 are provided with multiple first hollow portions 1028. These hollow portions greatly increase the resistance to deformation while reducing the weight of the end plates, thus improving operational flexibility and response speed. Furthermore, the provision of the first hollow portions 1028 also reduces material usage, lowers production costs, and enhances the economic efficiency and environmental friendliness of the equipment.

[0049] In one specific implementation, the first end plate 1015 and the second end plate 1016 are detachably connected to the scissor shaft 1018 and the power input shaft 1017.

[0050] In the drop tooth type picking assembly of the automatic chaff picker 100 of this application, the first end plate 1015 and the second end plate 1016 are all detachably connected to the drop tooth shaft 1018 and the power input shaft 1017. This design not only facilitates the quick replacement or adjustment of components during equipment maintenance and repair, but also improves the flexibility and adaptability of the equipment to cope with different working conditions and material characteristics.

[0051] like Figure 5 As shown, in one specific embodiment, the power input shaft 1017 is provided with a plurality of radially outwardly extending support portions 1034 in its middle region, and the support portions 1034 are detachably connected to the scissor shaft 1018.

[0052] In this application, the power input shaft 1017 has a plurality of support portions 1034 extending radially outward in its middle region. A connecting hole is provided at the extended end of each support portion 1034, through which the truncated gear shaft 1018 passes and is rotatably connected. Furthermore, the support portions 1034, the truncated gear shaft 1018, and the power output shaft are all detachably connected.

[0053] In another specific embodiment, a ring 1033 is sleeved in the middle region of the power output shaft, and the support portion 1034 is disposed on the ring 1033.

[0054] In one specific implementation, the support plate 1011 is provided with a plurality of second perforations, which are used to drain the mud and sand encased in the material.

[0055] In this application, multiple second perforations are specifically provided on the support plate 1011. The main function of these second perforations is to allow impurities such as mud and sand carried in the material to pass through the perforations, thereby achieving preliminary cleaning of the material. This design helps to improve the purity of the material in subsequent processing, reduce wear and tear on the equipment caused by mud and sand, and minimize the impact on the quality of the final product. In addition, through these second perforations, the machine can more effectively separate unwanted impurities, ensuring that the picked-up material is cleaner, thereby improving the quality of the final product.

[0056] In a second aspect, the present invention provides a grass block machine, which includes the aforementioned automatic grass-picking and chopping machine 100, and a briquetting device connected to the grass-chopping machine, the briquetting device pressing the chopped material into a block structure.

[0057] This utility model also provides a straw briquetting machine, which includes the aforementioned automatic straw-collecting and chopping machine 100, as well as a blower and a briquetting device connected to the chopping machine. In other words, the straw briquetting machine provided by this solution is a highly efficient agricultural device integrating an automatic straw-collecting and chopping machine 100, a blower, and a briquetting device. Its workflow begins with the automatic straw-collecting and chopping machine 100, which is responsible for collecting straw from the field and conveying it to the chopping mechanism 103 for cutting. After the straw is processed to an appropriate length by the chopping machine, it is then sucked in by the blower and conveyed to the briquetting device. In the briquetting device, the straw is compressed into compact blocks for easy storage and transportation. After briquetting, these straw blocks are output and bagged for subsequent transportation and use. The entire process automates straw collection, cutting, conveying, compression, and bagging, significantly improving production efficiency and reducing labor intensity.
