[0043] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0044] In some embodiments, combined with Figures 1 to 3As shown, a baler 1 is provided, including: a main body 10, including a crushing chamber 11; a harvesting mechanism 40, disposed on the main body 10, the harvesting mechanism 40 being used to harvest straw, the feed end of the crushing chamber 11 being connected to the discharge port of the harvesting mechanism 40; and a crushing mechanism 20, disposed on the main body 10. The crushing mechanism 20 includes: a cutter shaft 21 and a plurality of crushing parts 22, the cutter shaft 21 being disposed on the main body 10 and being rotatable relative to the main body 10; the plurality of crushing parts 22 being distributed on the cutter shaft 21 and located within the crushing chamber 11; wherein, the cutter shaft 21 drives the plurality of crushing parts 22 to rotate, so as to use the crushing parts 22 to crush the straw entering the crushing chamber 11.

[0045] The baler 1 disclosed herein includes a main body 10, a harvesting mechanism 40, and a crushing mechanism 20. The main body 10 includes a crushing chamber 11, which provides operating space for crushing straw. The harvesting mechanism 40 is disposed on the main body 10 and is used to harvest straw. The feed end of the crushing chamber 11 is connected to the discharge port of the harvesting mechanism 40, and the straw harvested by the harvesting mechanism 40 enters the crushing chamber 11 through the discharge port.

[0046] Combination Figure 3 and Figure 5 As shown, the crushing mechanism 20 includes: a cutter shaft 21 and multiple crushing parts 22. The cutter shaft 21 is disposed on the main body 10 of the equipment and can rotate relative to the main body 10 of the equipment. The multiple crushing parts 22 are distributed on the cutter shaft 21 and located in the crushing chamber 11. The cutter shaft 21 drives the multiple crushing parts 22 to rotate, so as to crush the straw entering the crushing chamber 11.

[0047] In contrast to related technologies that only harvest straw, the baler 1 provided in this disclosure, by incorporating a crushing mechanism 20, cuts and crushes the straw before baling, breaking long straw into short fragments. The crushed straw is more easily compacted after entering the baling chamber, significantly increasing the density and compactness of the bale. This effectively solves the problem of loose bales caused by excessively long straw, facilitating subsequent transportation, storage, and handling. Furthermore, the crushing process before baling ensures that the final straw bale is composed of short, crushed straw. For subsequent use (such as as feed), no complex secondary crushing process is required; the straw can be used directly, greatly reducing processing difficulty and costs, improving the convenience and economic value of straw use, and increasing the utilization rate of straw.

[0048] Furthermore, combined Figure 3 and Figure 5As shown, the crushing mechanism 20 includes a cutter shaft 21 and multiple crushing sections 22. The cutter shaft 21 is rotatably mounted on the main body 10 of the equipment via a support structure such as bearings, and its axial direction is approximately perpendicular to the conveying direction of the straw. The multiple crushing sections 22 are evenly distributed along the axial direction of the cutter shaft 21, and the crushing sections 22 are mounted on the axial side arms of the cutter shaft 21, so that they rotate synchronously with the rotation of the cutter shaft 21.

[0049] Optionally, combined Figure 5 As shown, the crushing part 22 includes: a cutter holder 221, which is disposed on the axial arm of the cutter shaft 21; and a cutter body 222, which is disposed on the cutter holder 221 and is used to crush straw.

[0050] In this embodiment, the crushing section 22 includes a cutting tool and a cutting tool body 222. A tool holder 221 is used to fix the cutting tool body 222 onto the cutting tool shaft 21. The cutting tool body 222 is the component that performs the crushing operation.

[0051] Optionally, the tool body 222 and the tool holder 221 are detachably connected, so that the tool body 222 can be easily replaced if it is damaged.

[0052] Optionally, combined Figure 5 As shown, the tool body 222 includes: a tool shank, one end of which is connected to the tool holder 221, and the tool shank is perpendicular to the tool shaft 21; and a cutting tool body, one end of which is connected to the other end of the tool shank. The tool body 222 is constructed as an integral structure and is bent.

[0053] In this embodiment, the cutter body 222 includes a cutter shank and a cutting blade. The cutter body 222 is a one-piece structure, which improves the structural strength of the cutter body 222. The cutting blade is bent relative to the cutter shank. During operation, the rotating cutting blade can effectively cut the straw, improving the crushing effect.

[0054] Optionally, one end of the tool shank is detachably connected to the tool holder 221 to facilitate the replacement of the tool body 222.

[0055] Optionally, the cutting blade body and the cutting tool shank are arranged perpendicular to each other, the cutting tool shank is arranged perpendicular to the cutting tool shaft 21, and the cutting blade body is arranged parallel to the axis of the cutting tool shaft 21. In this way, the cutting blade body is perpendicular to the straw conveying route, and the cutting blade body plays the role of blocking and cutting the straw, thereby improving the straw crushing effect.

[0056] Optionally, an angle is formed between the cutting blade body and the tool shank. The angle ranges from 90 degrees to 135 degrees. Alternatively, the angle ranges from 45 degrees to 90 degrees.

[0057] Optionally, combined Figure 5 As shown, multiple crushing sections 22 are distributed in multiple rows along the circumference of the cutter shaft 21, with each row containing multiple crushing sections 22 evenly spaced along the extension direction of the cutter shaft 21. Adjacent rows of crushing sections 22 are staggered. This even distribution of multiple crushing sections 22 along the extension direction of the cutter shaft 21 increases the contact area between the crushing sections 22 and the straw, thereby improving the straw crushing effect.

[0058] Optionally, combined Figure 5 As shown, each tool holder 221 is equipped with two tool bodies 222, and the cutting blades of the two tool bodies 222 extend in opposite directions.

[0059] In this embodiment, each cutter holder 221 is equipped with two cutter bodies 222. The cutting blades of the two cutter bodies 222 extend in opposite directions; that is, one of the two cutting blades extends toward one end of the cutter shaft 21, and the other extends toward the other end of the cutter shaft 21. When the cutter shaft 21 rotates, the cutting blades in both directions can perform bidirectional crushing of the straw, improving the uniformity and efficiency of crushing.

[0060] Optionally, combined Figure 5 As shown, the crushing mechanism 20 also includes: a belt drive wheel 23, which is disposed on the main body 10 of the equipment; a belt driven wheel 24, which is disposed on the main body 10 of the equipment and is connected to the cutter shaft 21; and a belt 25, which is wound around the belt drive wheel 23 and the belt driven wheel 24. The belt drive wheel 23 rotates to drive the belt 25 to rotate, which in turn drives the belt driven wheel 24 to rotate. The belt 25 drives the cutter shaft 21 to rotate from the drive wheel, so that the multiple crushing parts 22 crush the straw.

[0061] In this embodiment, the crushing mechanism 20 further includes a belt drive pulley 23, a belt driven pulley 24, and a belt 25. When the power drives the belt drive pulley 23 to rotate, the friction of the belt 25 drives the belt driven pulley 24 to rotate, which in turn drives the cutter shaft 21 and all the crushing parts 22 thereon to rotate at high speed, thereby crushing the straw entering the crushing chamber 11. The belt 25 drive method has the advantages of buffering and vibration absorption, simple structure, and low cost.

[0062] Optionally, combined Figure 3 and Figure 5 As shown, the crushing mechanism 20 also includes a crushing drive gear set 26, which is disposed on the main body 10 of the equipment. The input end of the crushing drive gear set 26 is connected to a power source, and the output end of the crushing drive gear set 26 is connected to a belt drive wheel 23. The crushing drive gear set 26 transmits the power from the power source to the belt drive wheel 23, driving the belt drive wheel 23 to rotate.

[0063] Optionally, combined Figure 1 and Figure 2 As shown, the baler 1 also includes: a traction arm 30, which is set on the main body 10 of the equipment. The traction arm 30 includes a power input shaft 31, which is used to connect to a power source; the crushing drive gear set 26 includes: a crushing drive gear, which is installed on the power input shaft 31; and a crushing driven gear, which is meshed with the crushing drive gear. The crushing driven gear is connected to the belt drive wheel 23 through the drive shaft 27.

[0064] In this embodiment, a power input shaft 31 is provided on the traction arm 30, which can typically be directly connected to the tractor's power output shaft. The crushing drive gear set 26 includes a crushing drive gear and a crushing driven gear. The crushing drive gear is mounted on the power input shaft 31. The crushing driven gear meshes with the crushing drive gear and is fixedly connected to the belt drive pulley 23 via the drive shaft 27. When the tractor drives the power input shaft 31 to rotate via the traction arm 30, power is sequentially transmitted to the crushing drive gear, the crushing driven gear, and then to the belt drive pulley 23 via the drive shaft 27, ultimately driving the crushing section 22 to rotate via the belt transmission system 25.

[0065] Optionally, both the crushing drive gear and the crushing driven gear are bevel gears.

[0066] The working process of the baler 1 for crushing is as follows:

[0067] The tractor pulls the baler 1 forward, and the harvesting mechanism 40 collects and transports the cut straw to the feed end of the crushing chamber 11. After entering the crushing chamber 11 through the feed end, the straw is cut and crushed into short pieces by the high-speed rotating crushing section 22. The thoroughly crushed straw is discharged from the discharge end of the crushing chamber 11 and enters the baling chamber of the baler 1. In the baling chamber, these short and broken straw pieces are more easily compacted by the compaction device and finally tied into tight, non-loose bales by the knotting mechanism. The entire process integrates harvesting, crushing, and baling, greatly improving operating efficiency and the quality of straw products.

[0068] Optionally, combined Figure 4 and Figure 6 As shown, the harvesting mechanism 40 includes a mounting body 41 and multiple harvesting blade assemblies 42. The mounting body 41 includes a material passage space 410, the outlet of which is connected to the feed end of the crushing chamber 11. The multiple harvesting blade assemblies 42 are arranged side by side on the mounting body 41, located in the material passage space 410, and the multiple harvesting blade assemblies 42 are rotatable relative to the mounting frame 411.

[0069] In this embodiment, multiple harvesting blade groups 42 that can rotate relative to the mounting body 41 are used to cut and crush the straw. Specifically, the material passage space 410 of the mounting body 41 provides operable space for the straw crushing process. The multiple harvesting blade groups 42 are used to cut the straw from the root, sever the straw, and move the harvested straw to the discharge port to enter the crushing chamber for crushing. Furthermore, by arranging multiple harvesting blade groups 42 along the width direction of the mounting body 41, the coverage area of ​​the harvesting blade groups 42 is increased, thereby increasing the amount of straw that the harvesting blade groups 42 can process simultaneously, and improving the harvesting and crushing efficiency.

[0070] Optionally, combined Figure 6 and Figure 7 As shown, the harvester assembly 42 includes a rotating shaft 420, a pick tooth 421 disposed on the rotating shaft 420, and a harvester blade 428, with the harvester blade 428 located below the pick tooth 421. There are multiple pick teeth 421, which are coaxially arranged and spaced apart sequentially along the length of the rotating shaft 420.

[0071] In this embodiment, the pick teeth 421 are located above the harvesting blades 428, and are used to collect the harvested straw. Each harvesting blade assembly 42 includes multiple pick teeth 421 and harvesting blades 428. All the pick teeth 421 and harvesting blades 428 are connected to the rotating shaft 420 and can rotate around the rotating shaft 420. The harvesting blades 428 are located at the bottom; in practical applications, the harvesting blades 428 are positioned near the ground. The harvesting blades 428 rotate relative to the rotating shaft 420, cutting the straw near the root to complete the straw harvesting operation. The multiple pick teeth 421 are located above the harvesting blades 428 and are spaced apart along the length of the rotating shaft 420. In the application scenario, multiple teeth 421 rotate relative to the rotating shaft 420 to collect and move the cut straw. Multiple teeth 421 are spaced apart along the length of the rotating shaft 420, and a material passage space 410 is provided between two adjacent teeth 421.

[0072] Optionally, combined Figure 6 and Figure 7 As shown, the paddle teeth 421 include: a first type of paddle teeth 422, a second type of paddle teeth 424, and a third type of paddle teeth 427.

[0073] The first type of tooth 422 is disposed on the rotating shaft 420. The first type of tooth 422 includes multiple first teeth 423 of the same shape and size. The second type of tooth 424 and the third type of tooth 427 are both located between the first type of tooth 422 and the harvesting tool 428. The second type of tooth 424 includes second teeth 425 and third teeth 426 of the same shape, the second teeth 425 being larger than the third teeth 426, and the second teeth 425 and third teeth 426 being staggered along the circumference of the second type of tooth 424.

[0074] In this embodiment, the reamer 421 includes three types of reamers: a first type reamer 422, a second type reamer 424, and a third type reamer 427. The first type reamer 422 has multiple first teeth 423 on its circumference, all of which are identical in shape and size. The second type reamer 424 has second teeth 425 and third teeth 426 intersecting on its circumference, with the second teeth 425 being larger than the third teeth 426. Along the length of the rotation axis 420, the second type reamer 424 is located between the first type reamer 422 and the harvesting tool 428. It should be noted that "size" refers to the geometric dimensions of teeth of the same shape, such as length, width, thickness, arc length, etc.

[0075] Optionally, combined Figure 7 As shown, the third type of tooth 427 includes a tooth body and a tooth tip. The third type of tooth 427 is a one-piece structure, which improves the strength of the tool. The tooth tip protrudes from the tooth body along the rotation direction of the third type of tooth 427, so that a certain angle is formed between the tooth tip and the tooth body. During the harvesting process, the tooth tip can play a role in gathering and limiting the straw, and cooperates with the tooth body to achieve the gathering and stirring effect of the straw.

[0076] For example, when the first tooth 423, the second tooth 425, and the third tooth 426 are all triangles, the dimension refers to the length of the side of the triangle and the angle of the vertex angle. When the first tooth 423, the second tooth 425, and the third tooth 426 are all parallelograms, the dimension refers to the length of the side of the quadrilateral and the angle between adjacent sides.

[0077] Of course, the shapes of the first tooth 423, the second tooth 425, and the third tooth 426 are not limited to triangles or parallelograms. Cutting tools with other shapes capable of performing cutting functions are all within the protection scope of this application, and will not be described in detail here. Furthermore, the triangles and parallelograms described in this example include the general outline shape of the teeth being triangular or parallelogram, and are not limited to regular shapes.

[0078] Optionally, the harvesting blade 428 includes a harvesting disc and harvesting blades. The harvesting disc is disc-shaped, and multiple harvesting blades are arranged around its circumference and evenly distributed at intervals. The harvesting blades are used to harvest straw. In this way, the harvesting blades 428 harvest the straw, and the teeth 421 gather and move the harvested straw into the crushing chamber.

[0079] In some embodiments, combined with Figure 6 As shown, the harvesting blade assembly 42 includes a main body, the top of which is connected to a rotating shaft 420, and the main body is rotatable relative to the rotating shaft 420. The main body is constructed as a cylinder, and first-type teeth 422, second-type teeth 424, third-type teeth 427, and harvesting blades 428 are all disposed on the periphery of the cylinder. By arranging multiple types of blades in the main body, the installation or removal of the blades can be completed in one go, facilitating assembly.

[0080] In some embodiments, the first type of pawl 422, the second type of pawl 424, the third type of pawl 427, and the harvesting blade 428 are all constructed as discs. The first type of pawl 422, the second type of pawl 424, the third type of pawl 427, and the harvesting blade 428 are all disposed on the rotating shaft 420 and are all rotatable relative to the rotating shaft 420. By having the first type of pawl 422, the second type of pawl 424, the third type of pawl 427, and the harvesting blade 428 respectively fitted onto the rotating shaft 420, if a particular type of blade is damaged, it can be replaced individually, reducing maintenance costs.

[0081] Optionally, combined Figure 6 As shown, the number of multiple harvester blade groups 42 is even. Two adjacent harvester blade groups 42 in the even number of harvester blade groups 42 form a pair of harvester blade groups 42, and the two harvester blade groups 42 in each pair of harvester blade groups 42 rotate in different directions to achieve the purpose of rolling the material into the material passage space 410.

[0082] In this embodiment, multiple harvesting blade sets 42 are paired up to form harvesting blade sets 42 pairs. The two harvesting blade sets 42 in each pair rotate in opposite directions, and the straw is rotated into the material passage space 410 for crushing by rotating in opposite directions.

[0083] Optionally, combined Figure 6 As shown, the mounting body 41 includes a mounting frame 411 and a enclosure portion 412. Multiple harvester blade assemblies 42 are disposed on the mounting frame 411. The mounting frame 411 includes a discharge port. The enclosure portion 412 is mounted on the mounting frame 411 and encloses a material passage space 410, which is connected to the discharge port.

[0084] In this embodiment, the mounting frame 411 is used to mount the harvesting mechanism 40 onto the main body 10 of the equipment. The mounting frame 411 also supports multiple harvesting blade sets 42. A baffle 412 is provided on the mounting frame 411, forming a material passage space 410 to provide operable space for straw harvesting. The mounting frame 411 is also provided with a discharge port communicating with the crushing chamber 11. After harvesting, the straw is propelled through the discharge port by the cooperation of multiple teeth and enters the crushing chamber 11 for crushing.

[0085] For example, in combination Figure 6 As shown, there are four sets of harvesting blades 42. These four sets of harvesting blades 42 are arranged sequentially along the width of the mounting body 41, and are numbered sequentially from one end of the mounting body 41 as Group 1, Group 2, Group 3, and Group 4. Groups 1 and 2 constitute one set of harvesting blades 42, and groups 3 and 4 constitute another set of harvesting blades 42. (Combined with...) Figure 1 As shown, the rotation directions of groups 1 and 2 are opposite, and the rotation directions of groups 3 and 4 are opposite. Groups 1 and 3 rotate in the same direction, and groups 2 and 4 rotate in the same direction. The rotation direction of each group is indicated by the dotted arrows in the diagram. Groups 2 and 3 are located on opposite sides of the discharge port. Thus, the straw, after being crushed by the four sets of harvesting blades 42, enters the crushing chamber 11 through the discharge port.

[0086] Optionally, combined Figure 7 As shown, the enclosure 412 includes a baffle plate 413 and a guide plate 414. The baffle plate 413 is disposed on the mounting frame 411. The guide plate 414 is disposed on the mounting frame 411, one end of the guide plate 414 is connected to the baffle plate 413, and the guide plate 414 is located on both sides of the discharge port.

[0087] In this embodiment, the guide plates 414 are located on both sides of the discharge port and are used to guide the crushed straw to the discharge port. The baffle plate 413 is located on the other side of the guide plate 414 and is used to limit the straw during the harvesting process to prevent the straw from flying out of the material passage space 410.

[0088] For example, in combination Figure 6 As shown, when there are four harvester blade sets 42, the arrangement of the four sets is as in the example above. There are two corresponding baffle plates 413, respectively located on both sides of the mounting frame 411, corresponding to the first and fourth harvester blade sets 42. There are two guide plates 414, respectively corresponding to the second and third harvester blade sets 42. Each side of the discharge port is equipped with a connected baffle plate 413 and guide plate 414. The baffle plates 413 and guide plates 414 on both sides of the discharge port provide a space for collecting the straw and also guide the harvested straw.

[0089] Optionally, the main body 10 of the equipment includes a baling chamber 50, which is connected to the discharge port of the crushing mechanism 20. The straw after being crushed by the crushing mechanism 20 is fed into the baling chamber 50 for baling. The mechanical structure for baling can adopt the mechanical structure of the existing baler 1, which will not be described in detail here.

[0090] Optionally, combined Figure 6 As shown, the baler 1 also includes a traction arm 30 and a transmission mechanism 43. The traction arm 30 is connected to the main body 10 of the equipment. The transmission mechanism 43 is disposed on the traction arm 30, and the output end of the transmission mechanism 43 is connected to multiple harvesting blade sets 42. The transmission mechanism 43 is used to drive the multiple harvesting blade sets 42 to rotate.

[0091] In this embodiment, the baler 1 is connected to an external power device via a traction arm 30 to drive the baler 1. A transmission mechanism 43 is disposed on the traction arm 30. The transmission mechanism 43 is used to connect to an external power source and transmit power to the harvesting blade assembly 42, driving the harvesting blade assembly 42 to operate and realize the harvesting of straw.

[0092] Optionally, the external power equipment includes, but is not limited to, a tractor. One end of the traction arm 30 is located on the main body 10 of the equipment, and the other end of the traction arm 30 is connected to the tractor, so that the tractor can drive the baler 1 to move in the field.

[0093] Optionally, the external power source includes an engine mounted on an external power device, with the output end of the engine connected to the input end of the transmission mechanism 43 to provide power to the crushing mechanism 20, thereby enabling harvesting and crushing operations.

[0094] Optionally, combined Figure 2 and Figure 4 As shown, the transmission mechanism 43 includes a power input shaft 31, a first gear set 431, and multiple second gear sets 432. The power input shaft 31 is mounted on the traction arm 30 and is used to connect to a power source. The input end of the first gear set 431 is connected to the power input shaft 31, and the power input shaft 31 drives the first gear set 431 to rotate. The multiple second gear sets 432 are arranged one-to-one with the multiple harvester blade sets 42. Adjacent second gear sets 432 are connected to each other via a first transmission shaft 433. The second gear sets 432 located on both sides of the first gear set 431 are connected to the output end of the first gear set 431 via a second transmission shaft 434. Both the first gear set 431 and the second gear set 432 are bevel gears.

[0095] In this embodiment, the power input shaft 31 of the transmission mechanism 43 is connected to an external power source, and the first gear set 431 is connected to the power input shaft 31. The first gear set 431 is connected to multiple second gear sets 432 via a second transmission shaft 434, and adjacent second gear sets 432 are connected via a first transmission shaft 433. Thus, the external power source drives the first gear set 431, which in turn drives the second gear sets 432 directly connected to it. The second gear set 432 at the end is driven by the second gear sets 432 connected to it. Furthermore, bevel gears are used to achieve a change in the transmission direction.

[0096] For example, in combination Figure 6 As shown, there are four sets of harvester blades 42. These four sets of harvester blades 42 are arranged sequentially along the width of the mounting body 41, and are numbered 1, 2, 3, and 4 from one end of the mounting body 41 to the other. There are also four sets of second gears 432, each corresponding to one set of harvester blades 42, and numbered 1, 2, 3, and 4 from one end of the mounting body 41 to the other. Each second gear set 432 includes a first bevel gear and a second bevel gear that mesh with each other. There is one first gear set 431. The first gear set 431 includes a driving bevel gear and a driven bevel gear that mesh with each other. The driving bevel gear is mounted on the power input shaft 31, and the driven bevel gear is mounted on the second transmission shaft 434. In this configuration, second gear sets 2 and 3 are located on either side of the first gear set 431. The first bevel gear in second gear set 2 is mounted on the second drive shaft 434, and along the length of the second drive shaft 434, the first bevel gears in second gear sets 2 and 3 are located on either side of the driven bevel gear. The first bevel gear in second gear set 1 is connected to the first bevel gear in second gear set 2 via the first drive shaft 433. The first bevel gear in second gear set 3 is connected to the first bevel gear in second gear set 432 via the first drive shaft 433. The second bevel gears in the four second gear sets 432 correspond one-to-one with the first, second, third, and fourth harvester blade sets 42.

[0097] The harvesting process of baler 1 is as follows:

[0098] When the baler 1 is running, the tractor is started to move the baler 1. At the same time, the engine drives the power input shaft 31 to rotate, which in turn drives the first gear set 431 to drive the first transmission shaft 433 to rotate, which in turn drives the second gear set 432 and the second transmission shaft 434 to rotate, thereby driving multiple harvesting blade sets 42 to rotate and achieve harvesting.
