Description

Technical Field

[0001] The present application relates to the technical field of agricultural equipment, and particularly relates to a harvester chassis device and a harvester. Background Art

[0002] A harvester is a special agricultural machine used for harvesting crops. For example, it can harvest grains such as corn. It greatly improves the harvesting efficiency through automated operations, reduces the labor intensity of farmers, and is an indispensable device in modern agricultural production. It is widely used in current agricultural production activities and occupies a large market share.

[0003] Nowadays, with the improvement of the level of automated agriculture, each manufacturer has developed its own brand of harvester. However, most of the harvesters of each manufacturer are dedicated bodies, with high prices and costs, and often can only be used for harvesting one kind of crop, with poor applicability. Moreover, since the harvesting of crops often concentrates in a certain period of time, after consumers purchase a harvester, they often only use it during the harvesting season, and it is mostly idle during other periods. And because most of the harvester chassis are of an integrated structure, which directly bears the harvesting equipment on the top, and there is a relatively complex power transmission mechanism inside the chassis frame, maintenance and repair are more difficult, with high costs, strong specialization of accessories, high prices, and poor versatility.

[0004] Therefore, the prior art needs to be further improved and enhanced. Utility Model Content

[0005] The present application provides a harvester chassis device and a harvester to solve problems in the prior art such as strong specialization of the harvester chassis device and the harvester, narrow application range, long idle time, difficult maintenance, and high costs.

[0006] The technical solution adopted in the present application is as follows:

[0007] The present application provides a harvester chassis device, including a harvester frame, a steering drive axle, a gearbox, a bracket, an engine housing, and a main drive axle. A bracket is provided on the steering drive axle, and the bracket is fixedly connected to one side of the engine housing. The other side of the engine housing is connected to the gearbox, and the gearbox is connected to the main drive axle. The harvester frame includes a working frame body and a support frame body, which are detachably connected to each other. One end of the support frame body is connected to the main drive axle, and the other end is connected to the bracket. The bottom of the working frame body is connected to the top of the support frame body, and there are multiple locking buckles for detachable connection between them.

[0008] As a preferred embodiment of the present application, the working frame body is an assembled integral structure, and the working frame body is detachably connected to the support frame body as a whole.

[0009] As a preferred embodiment of the present application, the harvester chassis device further includes an engine, which is placed in the engine housing, longitudinally arranged, and directly connected to the gearbox. The gearbox is internally provided with a clutch, and the housings of the two are integrally arranged.

[0010] As a preferred embodiment of the present application, the clutch is a dual-action clutch, including a main clutch release sleeve, a main clutch release lever connected thereto, a secondary clutch release sleeve, and a secondary clutch release lever connected thereto. The main clutch release lever controls the output of the traveling power, and the secondary clutch release lever controls the output of the working power.

[0011] As a preferred embodiment of the present application, the harvester chassis device further includes a main power output device. A power transmission shaft is connected between the main power output device and the gearbox. First power output shafts are arranged on both sides of the main power output device, and a second power output shaft is arranged on the side of the main power output device opposite to the connected power transmission shaft. The main drive axle transmits the traveling power.

[0012] As a preferred embodiment of the present application, the harvester chassis device further includes a secondary power output shaft, which is connected to the side of the engine housing close to the steering drive axle bracket, that is, the power output end on the opposite side of the engine flywheel, for outputting auxiliary working power.

[0013] As a preferred embodiment of the present application, an installation component is provided at the bottom of the support frame body close to the steering drive axle. A differential and a differential lock are provided inside the main drive axle, and a differential is provided inside the steering drive axle.

[0014] As a preferred embodiment of the present application, the harvester chassis device further includes a water tank and a radiator fan. The water tank and the radiator fan are arranged on the side of the support frame body, and the radiator fan is arranged on the side of the water tank close to the inside of the support frame body.

[0015] As a preferred embodiment of the present application, the harvester chassis device also has a first working installation position, a second working installation position, and a third working installation position. The first working installation position is located on the first power output shaft, the second working installation position is located on the second power output shaft, and the third working installation position is located on the secondary power output shaft. At least one of the three installs the work.

[0016] The present application also provides a harvester. Based on the harvester chassis device, a cab is provided at the top of the support frame body. A rotating driving operation platform is provided inside the cab, and the rotating driving operation platform can rotate based on the rotating shaft inside the cab. The harvester also includes a harvester material box and a lifting and tipping device. The harvester material box and the lifting and tipping device are arranged on the top of the working frame body, and the lifting and tipping device is arranged between the harvester material box and the working frame body.

[0017] Due to the adoption of the above technical solutions, the technical effects achieved by this application are as follows:

[0018] 1. This application provides a harvester chassis device. By setting the harvester frame to include a detachable working frame body and a support frame body, the harvester chassis device forms a modular structure, enabling the selection of whether to assemble the working frame body on the support frame body according to needs. On the one hand, it can improve the applicable range of the entire device, and different devices can be installed and disassembled on the working frame body as required. Compared with most harvesters in the prior art that use dedicated bodies and chassis, the split structure of this application has stronger applicability and can complete multiple tasks such as transportation, loading, and traction with one device, greatly reducing costs. On the other hand, this type of split and detachable structure leaves a certain installation space, facilitating maintenance. And because it can be disassembled, when there are problems with the structure of the power part of the chassis device, it can be more convenient to repair and troubleshoot, and the operation is more convenient. Moreover, through the split harvester frame structure, the rotating driving operation platform, and the modular assembly structure, one vehicle can be used for multiple purposes and can be applicable to tractors, self-propelled corn harvesters, self-propelled corn harvesters with ear and stalk harvesting, self-propelled corn grain combine harvesters, self-propelled green forage harvesters, etc.

[0019] 2. As a preferred embodiment of this application, the engine of this application is longitudinally arranged, and the longitudinally arranged engine can be directly connected to the gearbox. Compared with the hydraulic power working mode in the prior art, the direct connection of this application does not require power transition, has higher efficiency, and through gear transmission by the gearbox, the power loss is smaller, and gear transmission is easier to repair and maintain, making the equipment operation more convenient.

[0020] 3. As a preferred embodiment of this application, this application has a first power output shaft arranged on both sides and a second power output shaft arranged on the side opposite to the power transmission shaft (that is, the front end of the entire main power output device) in the main power output device, so that the entire main power output device forms a power transmission output structure of one input and three outputs. It can not only transmit the power transmitted by the power transmission shaft to the outside through the first power output shaft like a traditional right-angle gearbox to facilitate driving the cutter bar structure provided on the harvester, but also through the additionally provided second power output shaft. After the harvester frame is split, through the three-point suspension structure arranged around the second power output shaft, a backpack cutter bar can be suspended and other connectable structures can be additionally connected. For example, a trailer can be connected to play a role similar to that of a tractor towing, with a wider applicable range, and the power output is still transmitted by one power transmission shaft, making the structure simpler.

[0021] 4. As a preferred embodiment of the present application, the chassis device of the present application further includes a secondary power output shaft, which is arranged above the steering drive axle bracket, that is, connected to the power output end on the opposite side of the engine flywheel, and is used to output auxiliary operation power, capable of forming a new power mechanism. In this way, in addition to the main power output device with one input and three outputs mentioned above, other working devices can also be connected at the secondary power output shaft to provide power for them. And the support chassis is also provided with an installation component, which can be used as an installation position to position the additionally installed working devices. For example, when a cutting table is connected at the main power output device, a returning machine can be connected at the secondary power output shaft and the installation component, so that the whole harvester can realize the function of harvesting and returning to the field in one. Of course, other structures can also be set, which can further improve the applicability of the chassis device, realize multiple different functions with one chassis device, and thus save the input cost.

[0022] 5. The present application also provides a harvester, which adopts the above-mentioned harvester chassis device. The harvester has a steerable cab, enabling the driver to drive freely facing forward or backward. And, combined with the integrally detachable harvester frame, when the working frame body and the support frame body are integrally connected, a cutting table can be connected at the main power output device, and a harvester material box and a lifting and turning device can be arranged on the top of the working frame body, so that the harvester has the harvesting function it should have. For the cutting table, it can be set as a corn harvester cutting table, a spike and stalk combined harvester cutting table, a corn grain harvester cutting table, a green forage cutting table. For the harvester material box, a conveying channel connected to the cutting table should be provided to convey the harvested crops to the material box or the peeling machine respectively. And when maintenance is needed, the locking buckle between the working frame body and the support frame body can be directly removed for easy maintenance. In addition, when the harvesting is completed or harvesting work is not required, the whole working frame body can be removed, and of course the cutting table should also be removed. The cab rotates backward, so that the whole harvester can form a body similar to a tractor, and a trailer can be connected at the second power output shaft at the main power output device to carry out transportation work similar to a tractor, and thus carry out operations such as plowing, sowing, loosening, rotary tillage and transportation, which can greatly reduce the idle time after the harvester is purchased and improve the applicability and utilization rate of the whole harvester.

[0035] In order to more clearly illustrate the overall concept of this application, the following will be described in detail by way of examples in conjunction with the accompanying drawings of the specification.

[0036] In the following description, many specific details are set forth in order to fully understand this application. However, this application can also be implemented in other ways different from those described herein. Therefore, the protection scope of this application is not limited by the specific embodiments disclosed below.

[0037] In addition, in the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "top", "bottom", "inner", "outer", "axial direction", "radial direction", "circumferential direction", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0038] In the present application, unless otherwise clearly specified and limited, terms such as "installed", "connected", "connected to", "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or a communication connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the connection inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0039] In the present application, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0040] As Figures 1 to 6 shown, the present application provides a harvester chassis device, including a harvester frame 10, a steering drive axle 11, a gear transmission 12, a bracket 13, an engine 14 housing, and a main drive axle 15. A bracket 13 is provided on the steering drive axle 11. The bracket 13 is fixedly connected to one side of the engine 14 housing. The other side of the engine 14 housing is connected to the gear transmission 12. The gear transmission 12 is connected to the main drive axle 15. The harvester frame 10 includes a working frame body 20 and a support frame body 21, which are detachably connected to each other. One end of the support frame body 21 is connected to the main drive axle 15, and the other end is connected to the bracket 13. The bottom of the working frame body 20 is connected to the top of the support frame body 21, and there are multiple locking latches 22 for detachable connection between them.

[0041] Among them, as Figure 1 and Figure 2As shown, the length of the working frame body 20 is slightly greater than that of the support frame body 21, and a partial structure of the working frame body 20 at the rear protrudes in the length direction from the support frame body 21, so as to facilitate the setting of other load-bearing structures on the top of the working frame body 20. Of course, the lengths of the two should be adapted to each other to largely avoid the phenomenon of fracture when the working frame body 20 with a longer length supports other structures.

[0042] In addition, the harvester chassis device should be connectable to wheels. The wheels can be similar to those of traditional harvesters and are arranged at the steering drive axle 11 and the main drive axle 15. Moreover, the wheels of the present application can be made larger to facilitate smoother movement in the field.

[0043] As a preferred embodiment of the present application, the working frame body 20 is an assembled integral structure, and the whole working frame body 20 is detachably connected to the support frame body 21.

[0044] It can be understood that the integral working frame body 20 does not mean that the whole working frame body 20 is integrally formed. It can also be welded by multiple metal structures. Moreover, the integral structure mentioned here only indicates that when the working frame body 20 is disassembled or installed on the support frame body 21, the whole working frame body 20 and the devices carried thereon can be taken down integrally, with more prominent integration and modularization and more convenient disassembly and assembly.

[0045] In addition, during disassembly, since the working frame body 20 itself has multiple frame structures, a forklift can be used to move the whole working frame body 20. In addition, other disassembly methods can also be adopted, such as setting a jack to lift the working frame body 20.

[0046] As a preferred embodiment of the present application, the harvester chassis device further includes an engine 14. The engine 14 is placed in the engine 14 housing, and the engine 14 is longitudinally arranged and directly connected to the gearbox 12. A clutch is built in the gearbox, and the housings of the two are integrally arranged.

[0047] It can be understood that the clutch is arranged inside the housing of the gearbox, so its internal position is not directly shown in the drawings of the application. For the clutch, the clutch is a dual-action clutch, including a main clutch release sleeve, the main clutch release lever connected thereto, a secondary clutch release sleeve, and the secondary clutch release lever connected thereto. The main clutch release lever controls the output of the traveling power, and the secondary clutch release lever controls the output of the working power.

[0048] Specifically, the main clutch release sleeve and the auxiliary clutch release sleeve exhibit a structure similar to that of a casing. During use, the main clutch release lever and the auxiliary clutch release lever can operate simultaneously, that is, both can simultaneously bring the friction plates of the main clutch and the auxiliary clutch into contact with the transmission outer shaft and the transmission inner shaft respectively, so as to simultaneously achieve the output of traveling power and operating power.

[0049] As Figure 3 and Figure 4 shown, in order to show the longitudinal setting of the engine 14, part of the structure of the engine 14 housing is omitted in the figure. The longitudinal setting of the engine 14 (that is, along the length direction of the entire chassis device) makes the gear transmission 12 directly connected to the engine 14, and the structure connected to the transmission longitudinally form an approximate straight line. This not only makes the space occupied by these power devices smaller, facilitating maintenance, repair and disassembly, but also directly uses the gearbox for transmission, with small power loss and convenient maintenance, which can greatly improve work efficiency.

[0050] In a preferred embodiment, as Figure 3 shown, the harvester chassis device further includes a main power output device 23. A power transmission shaft 121 is connected between the main power output device 23 and the gear transmission 12. First power output shafts 231 are arranged on both sides of the main power output device 23, and a second power output shaft 232 is arranged on the side of the main power output device 23 opposite to the connected power transmission shaft 121. The main drive axle can be used to transmit traveling power to ensure the normal driving of the vehicle.

[0051] It can be understood that compared with the existing traditional technology, the main power output device 23 provided in this application can achieve one input and three outputs. It can not only realize the transmission of the previous traditional gearbox, but also, while the two first power output shafts 231 carry the power of equipment such as the cutting table 40, there is an additional second power output shaft 232, which can provide an installation position and power for other structures when the cutting table 40 is not required, making the versatility of the entire harvester chassis higher.

[0052] Furthermore, as Figure 5 shown, the harvester chassis device further includes a secondary power output shaft 24. The secondary power output shaft 24 is connected to the side of the engine 14 housing close to the steering drive axle 11, that is, connected to the output end on the opposite side of the engine flywheel, and is used to output auxiliary operation power. That is, as Figure 5 shown at the rear of the entire harvester chassis device, due to the setting of additional power equipment, compared with most traditional harvesters that can only transmit power to the front end, that is, as Figure 6The direction of the cutter bar 40 shown provides power for the cutter bar 40. The secondary power output shaft 24 provided in this application can output power towards the rear, facilitating the connection of other working devices at the rear. For example Figure 4 and Figure 5 In, an installation component 25 is provided at the bottom of the side of the support frame body close to the steering drive axle 11. It can cooperate with the secondary power output shaft 24 to connect and set the structure of the rotary tiller 41, so as to realize the function of harvesting and returning to the field in one. Cooperating with the aforementioned one-in-three-out main power output structure, it can further improve the versatility of the entire harvester chassis.

[0053] It should be noted that the chassis device of this application travels through tires. When working in the field, due to factors such as soft, muddy soil and small friction, phenomena such as slipping may occur. Therefore, the main drive axle of this application has a differential and a differential lock. A differential is provided inside the steering drive axle. When slipping occurs, the speed on the slipping side will be too fast due to reduced friction. After setting the differential lock and differential, the controllability of power transmission can be guaranteed, and to a great extent, the continuous power transmission caused by slipping and the situation of too fast tire speed can be avoided, thus facilitating steering and getting out of trouble.

[0054] This application also provides a harvester, based on the aforementioned harvester chassis device, as Figure 1 and Figure 2 shown, a cab 30 is provided at the top of the support frame body 21. A rotating driving operation platform is provided inside the cab 30. The rotating driving operation platform can rotate based on the inner rotating shaft of the cab 30. That is to say, when needed, the driving devices and the driver inside the entire cab 30 can be rotated towards the rear to make the driver's field of vision face the rear, facilitating the operation and running at the rear.

[0055] For the rotating driving operation platform, it should be provided with equipment and components such as rotation control, brake control, clutch control, steering control, throttle control, gear shift control, work output control, and instrument display control inside to ensure the normal use of the entire harvester. The setting of the rotating driving operation platform can enable the entire device to achieve two-way driving, and can switch between two-wheel drive and four-wheel drive for walking through the gear control of the rotating driving operation platform. Moreover, the harvester chassis retains the three-point suspension mounting position, so that the three-point suspension position can be set at the second mounting position, and it can be used as a tractor for plowing, sowing, loosening, rotary tilling, and transportation, etc., or as a harvester for harvesting work.

[0056] Furthermore, the harvester further includes a harvester material box 31 and a lifting and flipping device 32. The harvester material box 31 and the lifting and flipping device 32 are provided at the top of the working frame body 20. The lifting and flipping device 32 is provided between the harvester material box 31 and the working frame body 20.

[0057] In addition, the lifting and flipping device 32 and the harvester material box 31 referred to in this application mean that a lifting and flipping device 32 is provided on the working frame 20. When the harvester performs ear and stem combined harvesting and separate storage, it can not only make the most of the space of the harvester body, but also enable the self-unloading function of the separated materials, which is efficient and practical. The specific structure can refer to the structure and function in the Chinese Utility Model Patent CN218959517U, a lifting and flipping device 32 for the harvester material box 31 body.

[0058] Further, as Figure 3 and Figure 4 shown, the harvester further includes a water tank 33 and a radiator fan 34. The water tank 33 and the radiator fan 34 are arranged on the side of the support frame 21. The radiator fan 34 is arranged on the side of the water tank 33 close to the inside of the support frame 21, which can not only provide a heat dissipation effect for the inside of the vehicle frame, but also the side placement of the water tank 33 can further save the installation space inside and facilitate the maintenance, disassembly and assembly of the internal power connection part.

[0059] As a preferred embodiment of this application, the harvester further includes a first working installation position, a second working installation position and a third working installation position. The first working installation position is located on the first power output shaft 231, the second working installation position is located on the second power output shaft 232, and the third working installation position is located on the secondary power output shaft 24. At least one of the three installs a working device, providing multiple installation positions for installing working devices for the entire harvester and improving the versatility of the device.

[0060] Of course, when it is said here that the first working installation position is located on the first power output shaft 231, the second working installation position is located on the second power output shaft 232, and the third working installation position is located on the secondary power output shaft 24, it does not mean that the three installation positions are directly connected to the output ends of the three output shafts. Instead, around the output ends of the output shafts, three installation positions can be left for installing and setting different devices.

[0061] Specifically, as Figures 1 to 6 shown, in this state, the support frame 21 and the working frame 20 are connected to each other. A peeling machine, a harvester material box 31 and a lifting and flipping device 32 are arranged on the top of the working frame 20. The first working installation position can be connected to the cutting table 40 to enable the harvester to have a basic harvesting function, and the third working installation position can be connected to the rotary tiller 41 to change the entire harvester into a harvesting and tilling integrated machine to complete normal harvesting work; at the end of the harvest or in seasons when harvesting is not required, such as Figure 2 and Figure 3As shown, the locking buckle 22 between the working frame 20 and the support frame 21 can be unlocked, and the entire working frame 20 can be lifted by a support structure such as a forklift or a jack. At this time, the harvesting machine operation components carried above the working frame 20 can be removed together. At the same time, the cutting table 40 can be removed together, so that the harvesting machine forms the most original body structure. At this time, the rotating driving operation table inside the cab 30 can be rotated so that the driver can have a backward view and drive the body to move backward in the original direction. The second working position can be used as the towing bar of the tractor to connect the trailer, so as to realize a transportation function similar to that of a tractor, realizing two uses of one body, which greatly improves the applicability of the body, saves costs compared with the special body used in traditional harvesting machines, and can be self-installed with applicable and required working equipment according to needs to achieve other functions, further improving the versatility.

[0062] What is not described in this application can be realized by adopting or referring to the existing technology.

[0063] Each embodiment in this specification is described in a progressive manner. For the same or similar parts between the embodiments, reference can be made to each other. The key point of each embodiment is to illustrate the differences from other embodiments.

[0064] The above are only the embodiments of this application and are not used to limit this application. For those skilled in the art, various changes and modifications can be made to this application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the scope of the claims of this application.
