[0044] Fresh corn, also known as fruit corn, has the advantages of high nutritional value, good taste, high added value, good benefits, low fat and high fiber, and is popular among the public. In order to improve the harvesting efficiency of fresh corn, fresh corn harvesters are also widely used. Among them, the chassis of the fresh corn harvester is one of the indispensable components of the fresh corn harvester.

[0045] The existing fresh corn harvester chassis are divided into integral and articulated types. Among them, the integral chassis is more widely used, but the integral chassis has disadvantages such as large turning radius and poor maneuverability; the articulated chassis includes a frame, a cylinder and a transmission assembly, the frame includes a front frame and a rear frame, the front frame and the rear frame are hinged, the fixed end and the output end of the cylinder are respectively connected to the front frame and the rear frame, the transmission assembly includes a front axle, a rear axle and a power member, the power member is arranged on the front axle, and is used to provide power for the front axle; the power member drives the front axle to move, and drives the rear frame to rotate through the extension and contraction of the cylinder, thereby changing the angle of the front frame and the rear frame, and the front frame drives the rear frame to move, so as to realize the steering of the harvester chassis.

[0046] However, when the rear frame of the existing fresh corn harvester chassis is loaded, the oil cylinder is subjected to a large force, which affects the service life of the oil cylinder.

[0047] In view of this, the present application provides a fresh corn harvester chassis and a vehicle to solve the problem that the oil cylinder is subjected to a large force when the rear frame of the existing fresh corn harvester chassis is loaded.

[0048] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] Reference Figure 1 to Figure 2 As shown, the present application provides a fresh corn harvester chassis, including a frame 100, a cylinder 200 and a transmission mechanism 300, the frame 100 includes a front frame 110 and a rear frame 120, the transmission mechanism 300 includes a front axle 310 and a rear axle 320, the front axle 310 is arranged on the front frame 110, and the rear axle 320 is arranged on the rear frame 120.

[0050] The frame 100 further includes an articulated frame 130 , which is articulated to the front frame 110 , and connected to the rear frame 120 . An accommodating channel 400 is provided at the connection between the articulated frame 130 and the rear frame 120 , and the accommodating channel 400 penetrates the articulated frame 130 and the rear frame 120 along the longitudinal direction of the frame 100 .

[0051] At least one group of oil cylinders 200 is provided, and the oil cylinders 200 are arranged at the hinge of the articulated frame 130 and the front frame 110 , and the fixed end and the output end of the oil cylinder 200 are connected to the front frame 110 and the articulated frame 130 respectively.

[0052] In the above, there is a longitudinal displacement of the chassis at the connection between the articulated frame 130 and the rear frame 120. When the chassis of the fresh corn harvester needs to turn, the oil cylinder 200 operates to apply force to the front frame 110 and the articulated frame 130 respectively, and the articulated frame 130 is subjected to force and rotates relative to the front frame 110, and then the articulated frame 130 drives the rear frame 120 to rotate. The weight of the articulated frame 130 is less than the weight of the articulated frame 130 plus the rear frame 120. When the oil cylinder 200 is in operation, it applies force to the articulated frame 130, and the articulated frame 130 then drives the rear frame 120 to move. The displacement between the articulated frame 130 and the rear frame 120 buffers the force on the oil cylinder 200 during steering, prolongs the service life of the oil cylinder 200, and at the same time accelerates the overall steering speed of the frame 100, improving the steering efficiency.

[0053] Further, see Figure 1 , Figure 3 and Figure 4 As shown, the transmission mechanism 300 also includes a power assembly 330 and a transmission shaft 340. The power assembly 330 connects the front axle 310 and the transmission shaft 340. The accommodating channel 400 is used to accommodate the transmission shaft 340. The transmission shaft 340 connects the rear axle 320. The power assembly 330 is configured to output power to the front axle 310 and the transmission shaft 340 to drive the front axle 310 and the rear axle 320 to move.

[0054] In specific implementation, when the chassis of the fresh corn harvester needs to turn, the power assembly 330 outputs power to the front axle 310 and the transmission shaft 340 respectively, and the transmission shaft 340 transmits the power to the rear axle 320, so as to drive the front axle 310 and the rear axle 320 respectively; at the same time, the oil cylinder 200 operates to apply force to the front frame 110 and the articulated frame 130 respectively, and the articulated frame 130 is subjected to the force and rotates relative to the front frame 110, and then the articulated frame 130 drives the rear frame 120 to rotate until the front frame 110 and the articulated frame 130 rotate to a preset angle, and cooperate with the front axle 3 10 and the movement of the rear axle 320 to achieve steering; by setting up a receiving channel 400 for accommodating the transmission shaft 340, the power transmission from the transmission shaft 340 to the rear axle 320 is achieved. While the power assembly 330 drives the front axle 310, the power assembly 330 drives the rear axle 320 to move forward, realizing the four-wheel drive transmission of the chassis, avoiding the disadvantages of the prior art that the power assembly 330 only drives the front axle 310, and when the rear frame 120 is loaded with a large amount of force, the oil cylinder 200 is affected by excessive force and its service life is affected. The present application scheme prolongs the service life of the oil cylinder 200 and ensures the steering efficiency. At the same time, by setting up the rear axle 320 drive, the force at the hinge shaft between the front frame 110 and the hinge frame 130 is reduced, and the connection stability between the front frame 110 and the hinge frame 130 is improved.

[0055] It should be noted that the location of the accommodating channel 400 is the interference position between the transmission shaft 340 and the frame 100. Considering the practical application, after the accommodating channel 400 is opened, the overall force of the frame 120 is stable, the overall cost is low, and the feasibility is high.

[0056] Further, see Figure 2 and Figure 4 As shown, the transmission shaft 340 includes a front axle 341 and a rear axle 342. The front axle 341 is connected to the power assembly 330, and the rear axle 342 is connected to the rear frame 120. The front axle 341 is hinged to the rear axle 342, and the hinge is located on the side of the articulated frame 130 close to the front frame 110. The accommodating channel 400 is used to accommodate the rear axle 342.

[0057] In this way, when the power assembly 330 drives the rear axle 320 to move, the power assembly 330 first drives the front axle 341 to rotate, the front axle 341 drives the rear axle 342 to rotate, and the rear axle 342 transmits the driving force to the rear axle 320; when turning, the articulated frame 130 rotates compared to the front frame 110, and the accommodating channel 400 rotates accordingly. At the same time, the rear axle 342 rotates relative to the front axle 341, ensuring the power transmission of the drive shaft 340 during turning, ensuring the power transmission efficiency.

[0058] In one possible implementation, referring to Figure 4 As shown, the power assembly 330 includes a power member 331 , a front transmission 332 and a rear transmission 333 .

[0059] The power member 331 is disposed on the front axle 310 , and is connected to the front shaft 341 ; the front transmission 332 is disposed on the front axle 310 , and is connected to the front transmission 332 ; the rear transmission 333 is disposed on the rear axle 320 , and is connected to the rear shaft 342 .

[0060] Specifically, when the power assembly 330 needs to drive the frame 100 to move, the power member 331 outputs driving force to the front transmission 332 and the drive shaft 340 respectively, the front transmission 332 drives the front axle 310 to move, the drive shaft 340 transmits the driving force to the rear transmission 333, and the rear transmission 333 drives the rear axle 320 to move, thereby realizing the simultaneous movement of the front axle 310 and the rear axle 320 and improving the driving efficiency of the chassis.

[0061] Exemplarily, the power element 331 may be an axial piston variable displacement motor.

[0062] Further, the accommodating channel 400 includes a first channel and a second channel.

[0063] The first channel is opened on the articulated frame 130 and penetrates the articulated frame 130 longitudinally; the second channel is opened on the rear frame 120 and penetrates the rear frame 120 longitudinally, and the first channel and the second channel are communicated.

[0064] In the above, the first channel and the second channel are respectively arranged on the articulated frame 130 and the rear frame 120, and the two form a receiving channel 400 for accommodating the transmission shaft 340, realizing the power transmission from the transmission shaft 340 to the rear axle 320, ensuring the four-wheel drive transmission of the frame 100, and making the driving efficiency high.

[0065] It should be noted that in order to reduce the weight of the chassis and facilitate wiring and maintenance, Figure 1 and Figure 3 As shown, the front frame 110 is designed as a U-shaped structure, and the rear frame 120 is designed as an I-shaped structure. Specifically, the front frame 110 includes a first wing frame and a second wing frame, one end of the first wing frame and the second wing frame are connected to each other and the connection is at an acute angle, and the other end is connected to the front axle 310; the rear frame 120 includes a tail frame, at least two placement frames, an abutment plate and a fixed plate, the abutment plate is used to abut the hinge frame 130, the abutment plate and the fixed plate are vertically arranged and the two are distributed along the longitudinal direction of the vehicle, the tail frame is arranged at the end of the rear frame 120, one end of the placement frame is connected to the tail frame, and the other end is connected to the abutment plate. Among them, a first receiving hole is opened on the abutment plate, and a second receiving hole is opened on the fixed plate, and the first receiving hole and the second receiving hole together form a second channel.

[0066] In addition, in one example, Figure 2 and Figure 3As shown, there is at least one hinge point between the front frame 110 and the articulated frame 130 , and the hinge points are all located on the articulated axis. The arrangement of multiple hinge points improves the connection stability between the front frame 110 and the articulated frame 130 .

[0067] In one possible implementation, Figure 5 As shown, a sleeve 121 is provided between the abutting plate and the fixing plate, and the two ends of the sleeve 121 are connected to the first receiving hole and the second receiving hole respectively. The sleeve 121 realizes the connection between the abutting plate and the fixing plate, and strengthens the overall structure of the rear frame 120. At the same time, the sleeve 121 is used for the rotating shaft to pass through. The setting of the sleeve 121 realizes the protection of the rotating shaft, reduces the possibility of debris entering the second channel, and ensures the transmission efficiency of the rotating shaft.

[0068] In addition, if Figure 5 , Figure 6 and Figure 7 As shown, the fresh corn harvester chassis provided in the present application also includes a connecting tube 500 and a fixing member 600 .

[0069] The connecting tube 500 passes through the first channel and the second channel. One end of the connecting tube 500 is fixedly connected to the hinge frame 130 , and the other end of the connecting tube 500 is provided with an annular groove.

[0070] The fixing member 600 is semi-annular, and the outer diameter of the fixing member 600 is larger than the diameter of the second receiving hole. Two fixing members 600 are provided, and the two fixing members 600 are used to be fixedly connected after being clamped into the annular groove. There is a spacing between the relatively fixed fixing members 600 and the fixing plate, so that there is a longitudinal displacement between the articulated frame 130 and the rear frame 120, which buffers the force on the cylinder 200 during steering and improves the steering efficiency.

[0071] When it is necessary to connect the articulated frame 130 and the rear frame 120, the connecting sleeve 121 is fixed on the articulated frame 130, the connecting sleeve 121 passes through the second channel, and the two fixing members 600 are inserted into the annular groove and then fixed by bolts; the setting of the connecting tube 500 and the fixing member 600 realizes the longitudinal connection between the articulated frame 130 and the rear frame 120. At this time, the connection between the articulated frame 130 and the rear frame 120 is set at the accommodating channel 400, which improves the space utilization of the frame 100 while protecting the transmission shaft 340.

[0072] Furthermore, the outer periphery of the connecting tube 500 is arranged in a stepped shape, wherein the thickness of the connecting tube 500 arranged in the first channel portion is greater than the thickness of the connecting tube 500 arranged in the second channel portion. Exemplarily, the thickness of the connecting tube 500 arranged in the first channel portion is 50 mm, and the thickness of the connecting tube 500 arranged in the second channel portion is 30 mm. In view of the actual application and the stress conditions of the connecting tube 500, the strength of the connecting tube 500 arranged in the second channel portion meets the stress standards, and the reduction in the thickness of the connecting tube 500 can reduce the overall weight of the frame 100 and reduce the manufacturing cost.

[0073] In one example, a washer is provided between the fixing member 600 and the fixing plate. There is a longitudinal displacement between the articulated frame 130 and the rear frame 120. When the articulated frame 130 drives the rear frame 120 to rotate relative to the front frame 110, there is a longitudinal relative movement between the fixing member 600 and the fixing plate. The washer is provided between the fixing member 600 and the fixing plate to buffer the force between the two, thereby improving the connection stability between the articulated frame 130 and the rear frame 120.

[0074] In one possible implementation, Figure 3 As shown, at least two limit blocks 122 are provided on the rear frame 120 . The limit blocks 122 are provided on one side of the rear frame 120 abutting against the articulated frame 130 . The limit blocks 122 are respectively provided on both sides of the rotation direction of the articulated frame 130 , and there is a distance between the limit blocks 122 and the articulated frame 130 .

[0075] When the oil cylinder 200 acts on the articulated frame 130, the articulated frame 130 is driven to rotate relative to the front frame 110, and the articulated frame 130 drives the rear frame 120 to rotate. When the articulated frame 130 rotates to abut against the limit block 122, the relative movement of the articulated frame 130 and the rear frame 120 stops, and then the articulated frame 130 and the rear frame 120 rotate synchronously. The setting of the articulated frame 130 realizes the force buffering of the oil cylinder 200, and the setting of the limit block 122 realizes the limitation between the articulated frame 130 and the rear frame 120, thereby avoiding excessive rotation of the articulated frame 130 and the rear frame 120, and ensuring the steering safety between the articulated frame 130 and the rear frame 120.

[0076] It should be noted that, referring to the background technology, the existing articulated chassis is mostly a two-wheel drive transmission that only drives the front axle 310. In order to reduce the force on the hinge of the oil cylinder 200 during steering, the fixed end and the output end of the oil cylinder 200 are usually set away from the hinge axis of the front frame 110 and the rear frame 120, so the existing rotation angle is usually an obtuse angle. However, the chassis in this solution is a four-wheel drive transmission that drives the front axle 310 and the rear axle 320 at the same time. Compared with the existing technology, the oil cylinder 200 has a smaller burden during steering. Therefore, the fixed end and the output end of the oil cylinder 200 are set near the hinge axis of the front frame 110 and the rear frame 120, and the rotation angle can be an acute angle. Exemplarily, when the articulated frame 130 abuts against the limit block 122, the rotation angle of the articulated frame 130 compared to the front frame 110 is a limit angle, and the limit angle can be 45°.

[0077] In addition, the present application also provides a vehicle, including a vehicle body and any of the above-mentioned fresh corn harvester chassis.

[0078] In summary, the fresh corn harvester chassis provided by the present application, when the fresh corn harvester chassis needs to turn, the power member 331 outputs driving force to the front transmission 332 and the transmission shaft 340 respectively, the front transmission 332 drives the front axle 310 to move, the transmission shaft 340 transmits the driving force to the rear transmission 333, the rear transmission 333 drives the rear axle 320 to move, and the front axle 310 and the rear axle 320 are driven separately; at the same time, the oil cylinder 200 operates to apply forces to the front frame 110 and the articulated frame 130 respectively, the articulated frame 130 is subjected to the force and rotates relative to the front frame 110, and then the articulated frame 130 drives the rear frame 120 to rotate until the front frame 110 and the articulated frame 130 rotate to a preset angle, and the steering is realized by cooperating with the movement of the front axle 310 and the rear axle 320; by setting a receiving channel 400 for accommodating the transmission shaft 340, the power transmission from the transmission shaft 340 to the rear axle 320 is realized, and the four-wheel drive transmission of the chassis is realized, avoiding the disadvantage that the power component 330 in the prior art only drives the front axle 310, and when the rear frame 120 is loaded with a large load, the oil cylinder 200 is affected by excessive force and its service life is affected. The present application scheme prolongs the service life of the oil cylinder 200 and ensures the steering efficiency. At the same time, by setting the rear axle 320 drive, the force at the articulated shaft between the front frame 110 and the articulated frame 130 is reduced, and the connection stability between the front frame 110 and the articulated frame 130 is improved.

[0079] Those skilled in the art will easily conceive of other implementations of the present application after considering the specification and practicing the technical solutions disclosed herein.
