Description

Technical Field

[0001] This utility model relates to agricultural machinery, specifically a lateral and longitudinal attitude adjustment device for the chassis of a potato combine harvester in hilly and mountainous areas. Background Technology

[0002] Hilly areas are characterized by numerous mountains and scarce arable land, so potatoes are mostly planted in rugged, steep, and dangerous terrain. Potato harvesters operating in hilly and mountainous areas are highly susceptible to dangerous tipping over or violently overturning when working on steep slopes.

[0003] Chinese invention patent application number 202111644789.0 discloses an automatic anti-tipping adjustment device for a sugarcane harvester, including a chassis, a support frame, a left hydraulic cylinder, a right hydraulic cylinder, a hydraulic solenoid control valve, a single-axis gyroscope, left and right displacement sensors, a machine body, a controller, and an alarm. When the chassis tilts to the left or right, the controller sends a signal to the hydraulic solenoid control valve to control the piston rods of the left and right hydraulic cylinders to extend or retract, changing the tilt angle of the machine body, thereby maintaining the relative balance of the sugarcane harvester's center of gravity and preventing tipping.

[0004] The problem is that the mechanism can only adjust the center of gravity from the left and right, and can only prevent tipping over. It cannot adjust the center of gravity if it is tilted forward or backward. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a lateral and longitudinal attitude adjustment device for the chassis of a potato combine harvester in hilly and mountainous areas. This device can adjust the center of gravity in the left and right directions and the center of gravity in the front and back directions during the movement, so that the center of gravity of the whole machine and the machine body are kept horizontal, ensuring safety during operation.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical means:

[0007] A lateral and longitudinal attitude adjustment device for the chassis of a potato combine harvester for hilly and mountainous areas includes a tracked chassis and a working equipment base;

[0008] The lower frame is connected to a tracked chassis, which moves to drive the lower frame. The upper frame and the lower frame are connected and supported by a left-right leveling device. The left-right leveling device includes a hinged connection component and left-right adjustment hydraulic cylinders. The left-right adjustment hydraulic cylinders are connected at the four corners of the upper and lower frames. The upper and lower frames are also connected by a hinged connection component. The operation of the left-right adjustment hydraulic cylinders causes the upper frame to rotate around the hinge axis of the hinged connection component, thereby adjusting the center of gravity in the left-right direction.

[0009] The upper frame is connected to the work equipment seat via a front-to-back leveling device. The front-to-back leveling device includes a center-of-gravity adjustment metal block and a front-to-back adjustment hydraulic cylinder. The cylinder body of the hydraulic cylinder is fixedly connected to the upper frame, and the drive end of the hydraulic cylinder is connected to the center-of-gravity adjustment metal block. The center-of-gravity adjustment metal block is slidably or rollably mounted on the upper frame. The upper frame is connected to the work equipment seat via the center-of-gravity adjustment metal block, and this connection is fixed. The center-of-gravity adjustment metal block is driven to move back and forth by the hydraulic cylinder. The movement of the center-of-gravity adjustment metal block causes the work equipment seat to move back and forth, thus changing the center of gravity position.

[0010] Angle sensors and controllers are installed on both the lower and upper vehicle frames. The angle sensors monitor the changes in the angle between the lower and upper vehicle frames and the horizontal plane and send the data to the controller. The controller is connected to control the left-right leveling device and the front-back leveling device.

[0011] This leveling system is driven by front and rear adjusting hydraulic cylinders, making it more convenient and flexible. It can achieve large-range, large-scale, and stable adjustments. When the chassis is traveling on hilly or mountainous terrain and needs to climb slopes and overcome obstacles, the center of gravity of the entire machine will shift to the rear of the machine, making it very easy to tilt backward. At this time, the front and rear adjusting hydraulic cylinders push the trapezoidal metal block towards the front of the machine body, thereby adjusting the position of the metal column to achieve longitudinal leveling of the working equipment and overcome the backward tilting of the machine body. When the chassis is traveling on hilly or mountainous terrain and needs to go downhill, the center of gravity of the entire machine will shift to the front of the machine body, making it very easy to cause the machine to tilt forward or even roll over. At this time, the front and rear adjusting hydraulic cylinders push the trapezoidal metal block towards the rear of the machine body, thereby adjusting the position of the metal column to achieve longitudinal leveling of the working equipment and overcome the forward tilting of the machine body, thus maintaining the balance of the working equipment in the front and rear directions.

[0012] As a further improvement to this technical solution, two hinged connecting components are provided at intervals. Each hinged connecting component is provided with an upper connecting part, a hinge shaft, and a lower connecting part. The bottom end of the upper connecting part is hinged to the top end of the lower connecting part through the hinge shaft. The top end of the upper connecting part is fixedly connected to the upper frame, and the bottom end of the lower connecting part is fixedly connected to the lower frame.

[0013] By setting two hinged connecting parts, the axis where the hinge axis of the two hinged connecting parts is located is the axis of rotation of the upper frame driven to rotate. The rotation of the upper frame causes the center of gravity of this device to shift.

[0014] The aforementioned horizontal and vertical attitude adjustment device for the chassis of the hilly and mountainous potato combine harvester includes a trapezoidal metal block for center of gravity adjustment.

[0015] Because of its significant weight, the center of gravity adjustment metal block offers high stability. Its movement simultaneously moves the base of the work equipment forward and backward, easily altering the center of gravity's position in the front-to-back direction. Furthermore, the metal block's weight also contributes to a stable connection to the work equipment base, preventing vertical bouncing or shaking during operation.

[0016] The center of gravity adjustment metal block is provided with a center of gravity adjustment roller on its bottom surface. The center of gravity adjustment metal block adjusts its position by rolling on the surface of the upper frame through the center of gravity adjustment roller.

[0017] By setting up a center-of-gravity adjustment roller, the friction between the center-of-gravity adjustment metal block and the upper frame when driven is rolling friction, which reduces the resistance to movement.

[0018] The center of gravity adjusting metal block is fixedly connected to the base of the working equipment through two connecting columns.

[0019] By setting two connecting columns, it is convenient to connect the center-of-gravity adjustment metal block to the base of the working equipment.

[0020] The bottom of the working equipment seat is provided with seat rollers, which are connected to the working equipment seat through wheel axle connectors; the upper frame is provided with roller limiting guide frames at the corresponding positions of the wheel axle connectors, and the wheel axle connectors move within the limited range of the roller limiting guide frames.

[0021] The installation of the seat rollers not only increases the stability of the support for the working equipment seat, but also allows the roller axles to cooperate with the roller limit guide frame to limit the movement of the roller limit guide frame. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further illustrated below with examples of its implementation.

[0028] See Figure 1 , 2 As can be seen from point 3, the horizontal and vertical attitude adjustment device of the chassis of the hilly and mountainous potato combine harvester of this utility model consists of a tracked chassis 5, a lower frame 6, a left and right leveling device 7, an upper frame 8, a front and rear leveling device 9, and a working equipment seat 10.

[0029] The working equipment includes a digging shovel 1, a ground wheel 2 supporting the front of the digging shovel, and a passive shaking device 3 and a secondary conveying and lifting device 4 arranged diagonally above the digging shovel. After the potatoes are dug by the digging shovel 1, the passive shaking device 3 shakes them to remove the surface soil, and then the secondary conveying and lifting device 4 transports them to the collection box at the base 10 of the working equipment.

[0030] The lower frame 6 is connected to the tracked chassis 5. The tracked chassis 5 moves, driving the lower frame 6. The upper frame 8 and the lower frame 6 are connected and supported by a left-right leveling device 7. The left-right leveling device 7 is equipped with a hinged connecting component 701 and a left-right adjusting hydraulic cylinder 702. The left-right adjusting hydraulic cylinder 702 is connected to the four corners of the upper frame 8 and the lower frame 6. The upper frame 8 and the lower frame 6 are also connected by the hinged connecting component 701. The operation of the left-right adjusting hydraulic cylinder 702 causes the upper frame 8 to rotate around the hinge axis 7012 of the hinged connecting component 701, thereby adjusting the center of gravity in the left-right direction.

[0031] The upper frame 8 is connected to the work equipment seat 10 via a front-to-back leveling device 9. The front-to-back leveling device 9 is equipped with a center-of-gravity adjustment metal block 901 and a front-to-back adjustment hydraulic cylinder 905. The cylinder body of the front-to-back adjustment hydraulic cylinder 905 is fixedly connected to the upper frame 8, and the drive end of the front-to-back adjustment hydraulic cylinder 905 is connected to the center-of-gravity adjustment metal block 901. The center-of-gravity adjustment metal block 901 is slidably or rollably mounted on the upper frame 8. The upper frame 8 is connected to the work equipment seat 10 via the center-of-gravity adjustment metal block 901, and the connection between the center-of-gravity adjustment metal block 901 and the work equipment seat 10 is fixed. The center-of-gravity adjustment metal block 901 is driven to move back and forth by the front-to-back adjustment hydraulic cylinder 905. The movement of the center-of-gravity adjustment metal block 901 causes the work equipment seat 10 to move back and forth, thus changing the center of gravity position.

[0032] This leveling system is driven by front and rear adjustment hydraulic cylinders 905, making it more convenient and flexible. It can achieve large-range, large-scale, and stable adjustments. When the chassis is traveling on hilly or mountainous terrain with complex terrain and needs to climb slopes and overcome obstacles, the center of gravity of the entire machine will shift to the rear of the machine, making it very easy to tilt backward. At this time, the front and rear adjustment hydraulic cylinders 905 push the trapezoidal metal block 901 towards the front of the machine body, thereby adjusting the position of the metal column 902 to achieve longitudinal leveling of the working equipment 11 and overcome the backward tilting of the machine body. When the chassis is traveling on hilly or mountainous terrain and needs to go downhill, the center of gravity of the entire machine will shift to the front of the machine body, making it very easy to cause the machine to tilt forward or even roll over. At this time, the front and rear adjustment hydraulic cylinders 905 push the trapezoidal metal block 901 towards the rear of the machine body, thereby adjusting the position of the metal column 902 to achieve longitudinal leveling of the working equipment 11 and overcome the forward tilting of the machine body, thereby maintaining the balance of the working equipment 11 in the front and rear directions.

[0033] Two hinged connecting parts 701 are provided at intervals. Each hinged connecting part 701 is provided with an upper connecting part 7011, a hinge shaft 7012, and a lower connecting part 7013. The bottom end of the upper connecting part 7011 is hinged to the top end of the lower connecting part 7013 through the hinge shaft 7012. The top end of the upper connecting part 7011 is fixedly connected to the upper frame 8, and the bottom end of the lower connecting part 7013 is fixedly connected to the lower frame 6.

[0034] By setting two hinged connecting parts 701, the axis where the hinge axis of the two hinged connecting parts 701 is located is the rotation axis of the upper frame 8 driven to rotate. The rotation of the upper frame 8 causes the center of gravity of the device to shift.

[0035] The center-of-gravity adjusting metal block 901 is a trapezoidal metal block, which provides high stability. Due to its significant weight, the movement of the center-of-gravity adjusting metal block 901 simultaneously moves the work equipment base 10 back and forth, easily altering the position of the center of gravity in the forward and backward direction. Furthermore, the significant weight of the center-of-gravity adjusting metal block 901 also helps to stably connect the work equipment base 10, preventing it from vertically shaking or bouncing during operation.

[0036] The center of gravity adjustment metal block 901 is provided with a center of gravity adjustment roller 903 on its bottom surface. The center of gravity adjustment metal block 901 adjusts its position by rolling on the surface of the upper frame 8 through the center of gravity adjustment roller 903.

[0037] The center-of-gravity adjustment metal block 901 is fixedly connected to the work equipment base 10 via two connecting posts 902. By providing two connecting posts 902, it is convenient to connect the center-of-gravity adjustment metal block 901 to the work equipment base 10 using the two connecting posts 902.

[0038] The bottom of the work equipment base 10 is equipped with base rollers 906, which are connected to the work equipment base 10 via wheel axle connectors. The upper frame 8 is equipped with roller limiting guide frames 904 at positions corresponding to the wheel axle connectors, allowing the wheel axle connectors to move within the limited range of the roller limiting guide frames 904. The base rollers 906 not only increase the stability of the work equipment base 10 but also limit the movement of the roller limiting guide frames 904 by cooperating with their wheel axles.

[0039] The lower frame 6 and the upper frame 8 are each equipped with an angle sensor and a controller. The angle sensor monitors the changes in the angle between the lower frame 6 and the upper frame 8 and the horizontal plane, and sends the data to the controller. The controller is connected to control the left-right leveling device 7 and the front-back leveling device 9.

[0040] The above description is merely an example of a preferred and feasible implementation of this utility model, and is not intended to limit the scope of this utility model. All equivalent structural changes made based on the description and drawings of this utility model are included within the scope of this utility model.
