Detailed Implementation

[0018] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0019] This application discloses a transmission system 100 for a harvester 1000 and the harvester 1000. The transmission system 100 is intended to solve the problem that in the prior art, the transmission system 100 has poor diversion capacity during the transmission process, which may affect the normal operation of other machines if a malfunction occurs in one machine.

[0020] See Figures 1 to 2In one specific embodiment of this application, the harvester 1000 has multiple implements, and the transmission system 100 includes an engine output assembly 1, a first intermediate shaft assembly 2, and multiple implement transmission mechanisms 4. The first intermediate shaft assembly 2 includes a first intermediate shaft 21 and a first input wheel 22 and multiple first output wheels 23 respectively mounted on the first intermediate shaft 21. The first input wheel 22 is drivenly connected to the engine output assembly 1. At least one second intermediate shaft assembly 3 includes a second intermediate shaft 31 and a second input wheel 32 and multiple second output wheels 33 respectively mounted on the second intermediate shaft 31. The second input wheel 32 is drivenly connected to the first output wheel 23. The multiple implement transmission mechanisms 4 are connected to the multiple implements one-to-one, and the implement transmission mechanisms 4 are connected to the first output wheel 23 or the second output wheel 33.

[0021] In this application, the transmission system 100 receives kinetic energy from the engine output assembly 1 via a first input wheel 22, and then distributes the kinetic energy through multiple first output wheels 23. Part of the kinetic energy output by the multiple first output wheels 23 is directly connected to some of the tool transmission mechanisms 4 to drive the tools, while the other part is input to the second intermediate shaft assembly 3. The second intermediate shaft assembly 3 receives the kinetic energy from the first output wheels 23 via a second input wheel 32, and then distributes it again through multiple second output wheels 33, which are connected to other tool transmission mechanisms 4 respectively. In the kinetic energy transmission process, the transmission system 100 performs a first distribution through the first intermediate shaft assembly 2 and a second distribution through the second intermediate shaft assembly 3, making the transmission paths of each tool transmission mechanism 4 relatively independent, thereby reducing the impact of each tool on other tools and enhancing the stability and adaptability of the transmission system 100.

[0022] In this application, there is no limitation on the number of second intermediate shaft assemblies 3; that is, there can be one or more second intermediate shaft assemblies 3, as long as they can adapt to the arrangement of the harvester 1000 and the transmission path of the transmission system 100. Furthermore, unless otherwise specified, the components of the transmission system 100 in this application are generally installed on the main body of the harvester 1000 or other conventional installation locations, and kinetic energy transmission is achieved through pulleys or sprockets. When driven by pulleys, if one implement malfunctions, the pulley can slip, reducing the impact on other implements.

[0023] In practical applications, the harvester 1000 needs to be equipped with various implements, resulting in a compact overall layout. This makes it difficult to install the second intermediate shaft assembly 3 in the transmission system 100, or the transmission path may be difficult to adapt to the second intermediate shaft assembly 3 after installation. Therefore, in one embodiment of this application, the second intermediate shaft 31 is used to drive the header of the harvester 1000. The implement transmission mechanism 4 includes a feeding roller transmission mechanism 4a, which includes a feeding roller shaft 411 and a feeding roller input wheel 412 and a feeding roller output wheel 413 mounted on the feeding roller shaft 411. The feeding roller input wheel 412 is drivenly connected to the first output wheel 23, and the feeding roller output wheel 413 is drivenly connected to the second input wheel 32.

[0024] In this embodiment, the second intermediate shaft 31 is connected to the header of the harvester 1000 via a transmission. The second intermediate shaft 31 actually serves as the drive shaft of the header, driving the header to work through its own rotation. By merging the second intermediate shaft 31 with the drive shaft of the header, the transmission system 100 reduces the space occupied by the second intermediate shaft assembly 3. In practical applications, the transmission system 100 outputs power to the feed roller input wheel 412 of the feed roller via the first output wheel 23, and then outputs power to the second intermediate shaft 31 via the feed roller output wheel 413. While the second intermediate shaft 31 drives the header to work, the second output wheel 33 can also perform secondary diversion of kinetic energy.

[0025] In this embodiment, the specific arrangement of the second intermediate shaft 31 needs to be combined with the body layout of the harvester 1000. When the body layout of the harvester 1000 is different, the second intermediate shaft 31 can be combined or connected with the drive shafts of other implements. When there are multiple second intermediate shaft assemblies 3, similar adjustments can be made. The second intermediate shaft 31 can serve as the drive shaft of the header, and the second intermediate shaft 31 can also serve as the drive shaft of other implements.

[0026] Further, see Figure 1 The transmission system 100 also includes a first transition wheel 101, a bridge drive shaft, and a first bridge drive wheel 102 and a second bridge drive wheel 103 mounted on the bridge drive shaft. The first bridge drive wheel 102, the first transition wheel 101, and the feed roller output wheel 413 are sequentially connected in a transmission connection. The second bridge drive wheel 103 is connected in a transmission connection with the second input wheel 32.

[0027] In practical applications, the distance between the cutting table and the feed roller is relatively far, making it difficult to directly connect the output roller and the second input roller 32. Therefore, the transmission system 100 is equipped with a bridge drive shaft. The first bridge drive roller 102, the first transition roller 101, and the feed roller output roller 413 are sequentially connected by a sprocket. The first transition roller 101 can not only adjust the wrap angle of the feed roller output roller 413, but also facilitate the connection between the feed roller output roller 413 and the first transition roller 101.

[0028] Specifically, see Figure 1 and Figure 2 The multiple implement transmission mechanisms 4 include a reel transmission mechanism 4b, a cutter transmission mechanism 4c, and a feeding auger transmission mechanism 4d. The cutter transmission mechanism 4c is connected to one of the multiple second output wheels 33. The reel transmission mechanism 4b includes a reel input wheel 421, a reel transition shaft, and a second transition wheel 422 and a third transition wheel installed on the reel transition shaft. The second transition wheel 422 is connected in sequence to another second output wheel 33 and the feeding auger transmission mechanism 4d. The third transition wheel is connected to the reel input wheel 421.

[0029] In practical applications, the reel, cutter, and feed auger of the harvester 1000 are all connected to the second intermediate shaft assembly 3, receiving power from the secondary diversion of the power by the second intermediate shaft assembly 3. In fact, one of the multiple second output wheels 33 is directly connected to the cutter transmission mechanism 4c, driving the cutter. Another second output wheel 33 is sequentially connected to the second transition wheel 422 of the reel transmission mechanism 4b and the feed auger transmission mechanism 4d via chains, completing the drive of the reel and the feed auger. However, the installation positions of the reel and the feed auger are significantly different, making direct connection difficult. Therefore, the reel transmission mechanism 4b is additionally equipped with a reel transition shaft and a second transition wheel 422 and a third transition wheel mounted on the reel transition shaft, with the third transition wheel being connected to the reel input wheel 421.

[0030] It should be noted that the above embodiment is only one specific implementation of the power transmission path of the second intermediate shaft 31. In actual application, it can be appropriately adjusted according to the body layout of the harvester 1000, as long as it can complete the driving of each implement and the secondary diversion of power.

[0031] In one embodiment of this application, the plurality of machine transmission mechanisms 4 include a grain auger transmission mechanism 4e, a waste auger transmission mechanism 4f, a fan transmission mechanism 4g, and a sieve box transmission mechanism 4h; the transmission system 100 also includes an intermediate transition mechanism 104, the input wheel of the intermediate transition mechanism 104 is connected to one of the plurality of first output wheels 23, and the output wheel of the intermediate transition mechanism 104 is connected to the grain auger transmission mechanism 4e, the waste auger transmission mechanism 4f, the fan transmission mechanism 4g, and the sieve box transmission mechanism 4h respectively.

[0032] In this embodiment, the intermediate transition mechanism 104 receives kinetic energy from the first output wheel 23 through its input wheel. The intermediate transition mechanism 104 also drives the grain auger, impurity auger, blower, and sieve box by connecting its output wheel to the grain auger drive mechanism 4e, the impurity auger drive mechanism 4f, the blower drive mechanism 4g, and the sieve box drive mechanism 4h, respectively. The transmission system 100 is connected to various implements through the intermediate transition mechanism 104, making the transmission path more compact.

[0033] Furthermore, the screen box transmission mechanism 4h includes a screen box input wheel 441, a screen box transition shaft 442, and a fourth transition wheel 443 and a fifth transition wheel 444 installed on the screen box transition shaft 442. The fifth transition wheel 444 is connected to the screen box input wheel 441 in a transmission connection. The grain auger transmission mechanism 4e includes a grain auger shaft, and a grain auger input wheel 431 and a grain auger output wheel installed on the grain auger shaft. The grain auger output wheel is connected to the fan transmission mechanism 4g in a transmission connection. The grain auger input wheel 431, the waste auger transmission mechanism 4f, the fourth transition wheel 443, and the output wheel of the intermediate transition mechanism 104 are connected in a transmission connection in sequence.

[0034] In some embodiments, due to the limited layout of the harvester 1000, the grain auger, waste auger, blower, and screen box are difficult to connect directly. Therefore, in this embodiment, the screen box transmission mechanism 4h is additionally provided with a screen box transition shaft 442 and a fourth transition wheel 443 and a fifth transition wheel 444 mounted on the screen box transition shaft 442, thereby solving the connection difficulty caused by the installation position. Specifically, the fourth transition wheel 443 is sequentially connected to the grain auger input wheel 431, the waste auger transmission mechanism 4f, and the output wheel of the intermediate transition mechanism 104 via a chain drive, and the fifth transition wheel 444 is connected to the screen box input wheel 441, so that the output wheel of the intermediate transition mechanism 104 can smoothly transmit kinetic energy to the aforementioned implements. More specifically, the fourth transition wheel 443 can act as a reverse transmission wheel. With the help of the transmission chain between the intermediate transition mechanism 104 and the waste auger transmission mechanism 4f, this reverse transmission wheel can directly transmit power to the screen box input wheel 441 without the need for an additional intermediate transmission wheel, making the entire power transmission process compact and reliable. In addition, structures similar to the fourth transition wheel 443 in other transmission routes of this application can also be adapted by referring to the above method.

[0035] In one embodiment of this application, see Figure 1 and Figure 2 The multiple machine transmission mechanisms 4 include a crusher transmission mechanism 4i, which includes a crusher input wheel 451, a crusher transition shaft, and a sixth transition wheel and a seventh transition wheel 452 mounted on the crusher transition shaft. The sixth transition wheel is connected to one of the multiple first output wheels 23, and the seventh transition wheel 452 is connected to the crusher input wheel 451.

[0036] The crusher is one of the implements of the harvester 1000, and its location is relatively far from other implements. Therefore, in this embodiment, the crusher transmission mechanism 4i is directly connected to one of the multiple first output wheels 23. Furthermore, the crusher transmission mechanism 4i is additionally equipped with a crusher transition shaft and a sixth and seventh transition wheels 452 mounted on the crusher transition shaft, thereby solving the connection difficulties caused by the installation position. The sixth transition wheel is connected to the first output wheel 23, while the seventh transition wheel 452 is drive-connected to the crusher input wheel 451. The crusher transmission mechanism 4i is not connected to other implement transmission mechanisms 4, therefore, the crusher transmission mechanism 4i will not affect or be affected by other implement transmission mechanisms 4, resulting in relatively superior stability.

[0037] In another embodiment of this application, the plurality of implement transmission mechanisms 4 include a roller transmission mechanism 4j, which is connected to one of the plurality of first output wheels 23. The roller is one of the implements of the harvester 1000, and its position is relatively far from the other implements. Therefore, in this embodiment, the roller transmission mechanism 4j is directly connected to one of the plurality of first output wheels 23. The roller transmission mechanism 4j is not connected to other implement transmission mechanisms 4, so it does not affect or is affected by other implement transmission mechanisms 4, exhibiting excellent stability.

[0038] See Figure 1 and Figure 2 The multiple machine transmission mechanisms 4 include a grain unloading auger transmission mechanism 4k, which includes a grain unloading bottom auger transmission wheel 461, a grain unloading inclined auger transmission wheel 462, a grain unloading intermediate shaft 463, and a grain unloading input wheel 464 and a grain unloading output wheel 465 installed on the grain unloading intermediate shaft 463. The grain unloading output wheel 465, the grain unloading bottom auger transmission wheel 461, and the grain unloading inclined auger transmission wheel 462 are sequentially connected in a transmission manner. The engine output assembly 1 includes an engine output shaft 11 and two engine output wheels 12 installed on the engine output shaft 11. One of the two engine output wheels 12 is connected in a transmission manner to the first input wheel 22, and the other is connected in a transmission manner to the grain unloading input wheel 464.

[0039] The distance between the unloading auger and other implements is relatively far, making it difficult to connect them. However, because the unloading auger transmission mechanism 4k is not connected to the transmission mechanisms 4 of other implements, it does not affect or is affected by the operation of the other implement transmission mechanisms 4, exhibiting excellent stability. Specifically, the unloading auger can be divided into a bottom unloading auger and a slanted unloading auger. Therefore, the unloading auger transmission mechanism 4k is additionally equipped with an intermediate unloading shaft 463 and an input unloading wheel 464 and an output unloading wheel 465 mounted on the intermediate unloading shaft 463. The input unloading wheel 464 is directly connected to the engine output wheel 12 in the engine output assembly 1, while the output unloading wheel 465 is sequentially connected to the bottom unloading auger transmission wheel 461 and the slanted unloading auger transmission wheel 462 via a chain.

[0040] The unloading auger transmission mechanism 4k is relatively close to the engine output assembly 1. Therefore, in this embodiment, the unloading auger transmission mechanism 4k can be directly connected to the engine output assembly 1. When the body arrangement of the harvester 1000 is different, the transmission path of the unloading auger transmission mechanism 4k can be adjusted accordingly.

[0041] See Figure 2In another aspect, this application also proposes a harvester 1000, which includes the transmission system 100 for the harvester 1000 as described above. The harvester 1000 can be a combine harvester 1000, a corn harvester 1000, or a cotton harvester 1000; any harvester 1000 that includes the aforementioned transmission system 100 falls under the category of the harvester 1000 described in this application. The harvester 1000 drives multiple implements through the aforementioned transmission system 100, preventing a malfunction in one implement from affecting the operation of other implements. This harvester 1000 exhibits better stability and stronger adaptability.
