[0002] In recent years, small self-propelled transplanters have developed rapidly in China. Such transplanters are usually driven by a small-horsepower engine for traveling and planting systems, with a compact structure and simple operation, and are suitable for use in small plots, hilly mountainous areas and other regions. However, in some areas (such as plots with excessive soil moisture), due to the use of a traditional wheeled chassis, such transplanters are prone to a large amount of sticky mud, seriously affecting the chassis passability, and causing great damage to the field road surface, and having poor adaptability to operations in different regions. Summary of the Invention

[0048] The following will describe in detail the specific implementation manners of the present application with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and understanding the present application, and are not used to limit the present application.

[0049] Referring to Figure 1 and Figure 2 , the first exemplary embodiment of the present application provides a chassis of a transplanter, which includes:

[0050] Frame assembly 5; and

[0051] Axle assembly, including a front axle assembly 1 and a rear axle assembly 4 mounted on a frame assembly 5, and an interchangeable mounting structure is provided at the end of the front axle assembly 1 and / or the rear axle assembly 4;

[0052] Wheeled traveling mechanism 402, provided with a first mounting structure capable of being detachably connected to the interchangeable mounting structure; and

[0053] Tracked traveling mechanism 403, provided with a second mounting structure capable of being detachably connected to the interchangeable mounting structure, and the tracked traveling mechanism 403 and the wheeled traveling mechanism 402 can be alternatively mounted to the interchangeable mounting structure.

[0054] It should be noted that the interchangeable mounting structure provided at the end of the front axle assembly 1 and / or the rear axle assembly 4 above indicates that this application does not limit whether the interchangeable mounting structure is provided at the end of the front axle assembly 1 or the rear axle assembly 4. That is, the case where the interchangeable mounting structure is provided at any one of the ends of the front axle assembly 1 and the rear axle assembly 4, as well as the case where the interchangeable mounting structure is provided at both ends of the front axle assembly 1 and the rear axle assembly 4, are all within the scope of the concept of this application.

[0055] Through the above settings, the transplanting machine chassis of this application is provided with an interchangeable mounting structure at the end of the front axle assembly 1 and / or the rear axle assembly 4. This interchangeable mounting structure is suitable for mounting both the wheeled traveling mechanism 402 and the tracked traveling mechanism 403. Thus, when the transplanting machine operates in different regions, the traveling mechanism of the transplanting machine chassis can be flexibly switched according to actual needs, improving the operation adaptability. For example, in areas with relatively flat terrain and low soil humidity, the transplanting machine chassis can adopt the wheeled traveling mechanism 402 to improve traveling mobility; while in areas with high soil humidity, the transplanting machine chassis can switch to use the tracked traveling mechanism 403, thereby reducing the amount of mud sticking to the traveling mechanism, enhancing the passability of the transplanting machine chassis, reducing the rolling damage to the field by the traveling mechanism, and improving the traction force and turning performance of the transplanting machine chassis.

[0056] In some embodiments, the interchangeable mounting structure may include a mounting adapter plate 401, a mounting hole provided on the mounting adapter plate 401, and a bolt assembly detachably passing through the mounting hole. At this time, a first mounting hole corresponding to the mounting hole on the mounting adapter plate 401 needs to be provided on the first mounting structure of the wheeled traveling mechanism 402, so that the bolt assembly can pass through the mutually corresponding mounting hole and the first mounting hole to realize the detachable connection between the first mounting structure and the interchangeable mounting structure. Similarly, a second mounting hole corresponding to the mounting hole on the mounting adapter plate 401 needs to be provided on the second mounting structure of the tracked traveling mechanism 403, so that the bolt assembly can pass through the mutually corresponding mounting hole and the second mounting hole to realize the detachable connection between the second mounting structure and the interchangeable mounting structure.

[0057] In some embodiments, referring to Figure 3 and Figure 4 , the rear axle assembly 4 includes a first rear axle disposed at intervals left and right (the lateral outer end of which is connected to the wheeled traveling mechanism 402 or the crawler traveling mechanism 403) and a second rear axle (the lateral outer end of which is connected to the wheeled traveling mechanism 402 or the crawler traveling mechanism 403), a first hinge structure 205 fixed to the lateral inner end of the first rear axle, and a second hinge structure 207 fixed to the lateral inner end of the second rear axle.

[0058] In addition, the transplanting machine chassis further includes a lifting adjustment mechanism 2. The lifting adjustment mechanism 2 includes a first telescopic device 202 arranged in the front-rear direction (the front end of which can be connected to the telescopic device mounting seat 206), a connecting bracket 204 connected to the rear end of the first telescopic device 202, a first connecting structure 201 with the rear end connected to the connecting bracket 204, and a second connecting structure 203 with the rear end connected to the connecting bracket 204. The front end of the first connecting structure 201 is hinged to the first hinge structure 205, and the front end of the second connecting structure 203 is hinged to the second hinge structure 207.

[0059] With the arrangement of this embodiment, when the first telescopic device 202 extends along the A direction, it can drive the connecting bracket 204 to move backward. At the same time, the connecting bracket 204 pulls the first hinge structure 205 and the second hinge structure 207 backward and upward respectively through the first connecting structure 201 and the second connecting structure 203, so as to raise the first rear axle and the second rear axle, and further increase the ground clearance of the transplanting machine chassis. At the same time, the connecting arm fixed to the rear axle in the wheeled traveling mechanism 402 or the crawler traveling mechanism 403 swings upward along the B direction.

[0060] When the first telescopic device 202 shortens along the A direction, it can drive the connecting bracket 204 to move forward. At the same time, the connecting bracket 204 pushes the first hinge structure 205 and the second hinge structure 207 forward and downward respectively through the first connecting structure 201 and the second connecting structure 203, so as to lower the first rear axle and the second rear axle, and further reduce the ground clearance of the transplanting machine chassis. At the same time, the connecting arm fixed to the rear axle in the wheeled traveling mechanism 402 or the crawler traveling mechanism 403 swings downward along the B direction.

[0061] It can be seen that the ground clearance of the transplanting machine chassis of the present application is adjustable. Thus, when the transplanting machine operates in different regions, the ground clearance of the transplanting machine chassis can be adaptively adjusted according to the ridge surface height in the fields of each region, ensuring that the operation height of the transplanting machine matches the ridge surface height.

[0062] In some embodiments, the lateral inner ends of the first rear axle shaft and the second rear axle shaft can also be rotatably sleeved at both ends of the transmission shaft of the transmission mechanism 3 (for example, the transmission shaft of the gearbox) respectively. Thus, when the first rear axle shaft and the second rear axle shaft are lifted or lowered, the transmission mechanism 3 can also be lifted or lowered synchronously.

[0063] In some embodiments, the first connection structure 201 is formed as a connecting rod, and the second connection structure 203 is formed as a second telescopic device. When the first telescopic device 202 does not operate and the second telescopic device performs a telescopic action, the second telescopic device can drive the second hinge structure 207 to lift or lower, so that the ground clearance of the second rear axle shaft can be adjusted independently, which is equivalent to adjusting the height difference between the first rear axle shaft and the second rear axle shaft. In this way, when the transplanter operates in a sloping field and causes the chassis to be uneven left and right, the chassis can be leveled left and right by the telescopic action of the second telescopic device, which is beneficial to improving the planting qualification rate of the transplanter in a sloping field.

[0064] In some embodiments, the lifting and adjusting mechanism 2 further includes a guide rod 208 arranged in the front-rear direction and passing through the connecting bracket 204. The guide rod 208 is slidably matched with the connecting bracket 204 and can play a role in guiding and improving stability when the connecting bracket 204 moves forward and backward.

[0065] In some embodiments, referring to Figure 5 , the wheeled traveling mechanism 402 includes wheels 407 and wheel axles. The inner and outer ends of the wheel axles in the lateral direction are respectively provided with a first inner mounting structure and a first outer mounting structure, and both the first inner mounting structure and the first outer mounting structure can detachably mount the wheels 407. In this way, when it is necessary to increase the wheelbase, the wheels 407 can be mounted on the first outer mounting structure, and when it is necessary to reduce the wheelbase, the wheels 407 can be mounted on the first inner mounting structure, so that the chassis of the transplanter can adjust the wheelbase according to different crop row spacings, improving the operation adaptability of the chassis of the transplanter.

[0066] In some embodiments, referring to Figure 6 , the crawler-type traveling mechanism 403 includes crawler wheels 408 and crawler wheel axles. The inner and outer ends of the crawler wheel axles in the lateral direction are respectively provided with a second inner mounting structure and a second outer mounting structure, and both the second inner mounting structure and the second outer mounting structure can detachably mount the crawler wheels 408. In this way, when it is necessary to increase the wheelbase, the crawler wheels 408 can be mounted on the second outer mounting structure, and when it is necessary to reduce the wheelbase, the crawler wheels 408 can be mounted on the second inner mounting structure, so that the chassis of the transplanter can adjust the wheelbase according to different crop row spacings, improving the operation adaptability of the chassis of the transplanter.

[0067] In some embodiments, referring to Figure 7, the rear axle assembly 4 includes a rear axle (such as the aforementioned first rear axle and second rear axle), the rear axle includes a rear axle main shaft 404 and a rear axle telescopic shaft 406 that form a plug-in fit that can slide horizontally, and a first tightening and loosening structure 405 for tightening and loosening the rear axle main shaft 404 and the rear axle telescopic shaft 406 (such as a positioning pin shaft or other tightening and loosening structures that can be used). In this way, by loosening the first tightening and loosening structure 405, the rear axle telescopic shaft 406 can slide relative to the rear axle main shaft 404 to adjust the total length of the rear axle, so as to adjust the wheelbase between the two wheels 407 (or crawler wheels 408) respectively connected to the two lateral ends of the rear axle assembly 4. After adjusting the total length of the rear axle, the first tightening and loosening structure 405 can be re-locked to make the rear axle main shaft 404 and the rear axle telescopic shaft 406 relatively fixed, thereby determining the wheelbase. In this way, the wheelbase of the transplanting machine chassis can be adjusted according to different crop row spacings, improving the operation adaptability of the transplanting machine chassis.

[0068] In some embodiments, referring to Figure 8 , the front axle assembly 1 includes a front axle, the front axle includes a front axle main shaft 101 and a front axle telescopic shaft 104 that form a plug-in fit that can slide horizontally, and a second tightening and loosening structure 103 for tightening and loosening the front axle main shaft 101 and the front axle telescopic shaft 104 (such as a positioning pin shaft or other tightening and loosening structures that can be used). In this way, by loosening the second tightening and loosening structure 103, the front axle telescopic shaft 104 can slide relative to the front axle main shaft 101 to adjust the total length of the front axle, so as to adjust the wheelbase between the two wheels 407 (or crawler wheels 408) respectively connected to the two lateral ends of the front axle assembly 1. After adjusting the total length of the front axle, the second tightening and loosening structure 103 can be re-locked to make the front axle main shaft 101 and the front axle telescopic shaft 104 relatively fixed, thereby determining the wheelbase. In this way, the wheelbase of the transplanting machine chassis can be adjusted according to different crop row spacings, improving the operation adaptability of the transplanting machine chassis.

[0069] In addition, a limiting structure 102 (such as a limiting pin shaft or the like) can be provided on the front axle, and the limiting structure 102 is used to limit the maximum retraction amplitude of the front axle telescopic shaft 104 in the front axle main shaft 101.

[0070] In some embodiments, continue to refer to Figure 8, the front axle assembly 1 includes a front axle shaft, a front axle support shaft 106, a front axle sliding sleeve 108, a connecting seat 109, and a third tightening and loosening structure 107. The front axle sliding sleeve 108 is slidably sleeved on the front axle support shaft 106 and is tightened and loosened by the third tightening and loosening structure 107 (for example, a positioning pin shaft or other tightening and loosening structures can be used). The connecting seat 109 connects the lateral outer end of the front axle shaft to the front axle sliding sleeve 108 (when the front axle shaft is provided with a front axle telescopic shaft 104, the connecting seat 109 and the front axle telescopic shaft 104 can be fixed by a positioning bolt 105). In this way, by loosening the third tightening and loosening structure 107, the front axle sliding sleeve 108 can slide relative to the front axle support shaft 106 to adjust the ground clearance of the front axle sliding sleeve 108. Since the connecting seat 109 connects the lateral outer end of the front axle shaft to the front axle sliding sleeve 108, it is equivalent to adjusting the ground clearance of the front axle shaft. Thus, when the transplanter operates in different regions, the ground clearance of the transplanter chassis can be adaptively adjusted according to the ridge surface height of the fields in each region to ensure that the operating height of the transplanter matches the ridge surface height.
