DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Embodiment: This embodiment provides a power chassis dedicated to tobacco planting in hilly and mountainous areas, see Figure 1-5 Specifically, it includes a rectangular frame 1, which serves as the main structural frame of the entire chassis and provides a mounting base for other components to ensure the stability and bearing capacity of the overall structure. I-shaped frames 2 are fixed at the four corners of the bottom surface of the rectangular frame 1. The I-shaped frames 2 are distributed at the four corners of the bottom surface of the rectangular frame 1 and are connected to the rectangular frame 1 to further enhance the structural stability. At the same time, they provide mounting positions for components such as anti-skid wheels 5, V-shaped brackets 15, and U-shaped brackets 7;

[0034] Each I-shaped frame 2 is provided with an anti-skid wheel 5 on the outside. The anti-skid wheel 5 is in direct contact with the ground to provide power support for the movement of the chassis. Its anti-skid design helps to walk on complex terrain in hilly and mountainous areas, enhances grip and prevents slipping.

[0035] A pair of symmetrically distributed reinforcing beams 3 are fixed on both sides of the rectangular frame 1. The reinforcing beams 3 are symmetrically distributed on both sides of the rectangular frame 1 to enhance the structural strength of the rectangular frame 1 and improve the overall bearing capacity of the chassis. Triangular plates 4 are fixed on both sides of the bottom surface of each reinforcing beam 3. Each triangular plate 4 is fixedly connected to the adjacent I-shaped frame 2. The triangular plates 4 are fixedly arranged on both sides of the bottom surface of the reinforcing beam 3 and are fixedly connected to the adjacent I-shaped frame 2. Through the stability principle of the triangle, the connection between the rectangular frame 1 and the I-shaped frame 2 is further reinforced to improve the overall structural stability.

[0036] The upper and lower sides of the outer side surface of the I-shaped frame 2 are respectively hinged with a V-shaped bracket 15 and a U-shaped bracket 7 with openings facing inward. The V-shaped bracket 15 is hinged to the top of the outer side surface of the I-shaped frame 2, and is movably hinged to the second U-shaped seat 14 through its two open ends, so as to provide support and connection for the anti-skid wheel 5, and can be hinged and swung when the terrain changes to adapt to the rough terrain. The U-shaped bracket 7 is hinged to the bottom of the outer side surface of the I-shaped frame 2, and is movably hinged to the first U-shaped seat 6 through its two open ends, so as to provide support and connection for the anti-skid wheel 5, and work together with the V-shaped bracket 15 to cooperate with the swing when the terrain changes to ensure the stability of the chassis;

[0037] A suspended fixing ring 17 is provided between the V-shaped bracket 15 and the U-shaped bracket 7. The fixing ring 17 is suspended between the V-shaped bracket 15 and the U-shaped bracket 7. A rotating shaft 19 is inserted for internal rotation to connect and fix the rotating shaft 19 so that it can rotate stably. The internal rotation of the fixing ring 17 is inserted with a rotating shaft 19 distributed throughout. The outer end of the rotating shaft 19 is fixedly connected to the middle of the anti-skid wheel 5. The outer end of the rotating shaft 19 is fixedly connected to the middle of the anti-skid wheel 5. The inner end is connected to the driving shaft 22 through a transmission mechanism to transmit the power of the driving shaft 22 to the anti-skid wheel 5, thereby driving the anti-skid wheel 5 to rotate;

[0038] A T-shaped through hole is opened in the middle of the inner side surface of the I-shaped frame 2, and a servo motor 21 with the output end facing outward is installed inside the T-shaped through hole. The servo motor 21 is installed in the T-shaped through hole in the middle of the inner side surface of the I-shaped frame 2, with the output end facing outward, to provide a power source for the chassis, and to drive the drive shaft 22 to rotate by controlling the rotation of the motor shaft. A drive shaft 22 is fixedly provided at the motor shaft end of the servo motor 21, and the outer end of the drive shaft 22 rotates through the T-shaped through hole, and the outer end of the drive shaft 22 is connected to the inner end of the rotating shaft 19 through a transmission mechanism. One end of the drive shaft 22 is fixedly connected to the motor shaft end of the servo motor 21, and the other end is connected to the inner end of the rotating shaft 19 through a transmission mechanism, so that the power of the servo motor 21 is transmitted to the rotating shaft 19, thereby driving the anti-skid wheel 5 to rotate.

[0039] In the specific implementation process, Figure 3 and Figure 4 As shown, a pair of second U-shaped seats 14 are fixedly provided on the top of the outer side of the I-shaped frame 2, and both ends of the opening of the V-shaped bracket 15 are respectively movably hinged to the pair of second U-shaped seats 14;

[0040] A pair of first U-shaped seats 6 are fixedly disposed at the bottom of the outer side surface of the I-shaped frame 2, and both ends of the opening of the U-shaped bracket 7 are respectively movably hinged to the pair of first U-shaped seats 6;

[0041] A second spherical sleeve 16 with an opening facing downward is fixedly disposed in the middle of the V-shaped bracket 15. The second spherical sleeve 16 is fixedly disposed in the middle of the V-shaped bracket 15 with an opening facing downward and is hinged to the outer end of the Z-shaped connecting rod 18, so that the Z-shaped connecting rod 18 can flexibly swing within a certain range to adapt to the angle change of the V-shaped bracket 15 when the terrain changes.

[0042] A first spherical sleeve 8 with an upward opening is fixedly disposed in the middle of the U-shaped bracket 7. The first spherical sleeve 8 is fixedly disposed in the middle of the U-shaped bracket 7 with an upward opening, and is hinged to the outer end of the Z-shaped connecting rod 18. The first spherical sleeve 8 cooperates with the second spherical sleeve 16 to enable the Z-shaped connecting rod 18 to adapt to the relative movement between the V-shaped bracket 15 and the U-shaped bracket 7, thereby ensuring the stability of the rectangular frame 1.

[0043] A pair of symmetrically distributed Z-type connecting rods 18 are fixed on the upper and lower surfaces of the fixing ring 17, and the outer ends of the pair of Z-type connecting rods 18 are respectively hingedly inserted in the second spherical sleeve 16 and the first spherical sleeve 8. The Z-type connecting rods 18 are symmetrically distributed on the upper and lower surfaces of the fixing ring 17, and the outer ends are respectively hingedly inserted in the second spherical sleeve 16 and the first spherical sleeve 8, connecting the V-shaped bracket 15 and the U-shaped bracket 7. When the terrain changes, the hinged swing thereof assists the rectangular frame 1 to maintain stability.

[0044] In the specific implementation process, Figure 3 and Figure 4 As shown, a pair of third U-shaped seats 9 are fixed at two corners of the top surface of the U-shaped bracket 7. The third U-shaped seats 9 are fixed at two corners of the top surface of the U-shaped bracket 7 to provide a movable hinged installation position for the piston sleeve 10. A movable hinged piston sleeve 10 is provided in the opening of each third U-shaped seat 9. The piston sleeve 10 is movably hinged with the third U-shaped seat 9, and a piston connecting rod 11 is slidably inserted inside. When the terrain changes, the piston connecting rod 11 slides in the piston sleeve 10 to play a buffering and regulating role.

[0045] A pair of oblique brackets 13 are fixedly arranged on the top of the outer side surface of the I-shaped frame 2. The oblique brackets 13 are fixedly arranged on the top of the outer side surface of the I-shaped frame 2 to provide a movable hinged installation position for the piston connecting rod 11. A movable hinged piston connecting rod 11 is arranged in the opening of each oblique bracket 13. The bottom end of each piston connecting rod 11 is slidably inserted in the piston sleeve 10 on the same side. The bottom end of the piston connecting rod 11 is slidably inserted in the piston sleeve 10. When the terrain changes, the piston slides in the piston sleeve 10 with the swing of the U-shaped bracket 7. Through the cooperation with the piston sleeve 10 and the action of the tension spring 12, the vibration energy is absorbed to keep the chassis stable.

[0046] A first concentrically fixed ring is sleeved on the middle and lower part of the piston sleeve 10, and a second concentrically fixed ring is sleeved on the middle and upper part of the piston connecting rod 11. The first ring and the second ring are concentrically fixed on the middle and lower part of the piston sleeve 10 and the middle and upper part of the piston connecting rod 11 respectively, and are used to fix the two ends of the tension spring 12. A tension spring 12 is fixed between the first ring and the second ring. The tension spring 12 is sleeved on the piston sleeve 10 and the piston connecting rod 11. The tension spring 12 is sleeved on the piston sleeve 10 and the piston connecting rod 11, and the first ring and the second ring are connected at both ends respectively. When the piston connecting rod 11 slides in the piston sleeve 10, the tension spring 12 is deformed, which plays a buffering and shock-absorbing role, thereby ensuring the stability of the rectangular frame 1 when walking on rough terrain.

[0047] It should be noted that: in this embodiment, the transmission mechanism includes a transmission shaft 24, the inner end of the rotating shaft 19 is hingedly provided with a first rotating sleeve 20, the outer end of the driving shaft 22 is hingedly provided with a second rotating sleeve 23, and the transmission shaft 24 is slidably inserted between the first rotating sleeve 20 and the second rotating sleeve 23. The transmission shaft 24 is slidably inserted between the first rotating sleeve 20 and the second rotating sleeve 23, and serves as an intermediate component for power transmission between the driving shaft 22 and the rotating shaft 19 to ensure that the two can rotate synchronously.

[0048] A first U-shaped ear seat is fixedly provided at the inner end of the rotating shaft 19, and a second U-shaped ear seat is fixedly provided at the hinged end of the first rotating sleeve 20. The first U-shaped ear seat and the second U-shaped ear seat are cross-distributed and movably hinged through a first cross pin. The first rotating sleeve 20 is hinged to the inner end of the rotating shaft 19, and is connected to the rotating shaft 19 through the first cross pin, and can rotate with the rotating shaft 19, and transmit the power of the transmission shaft 24 to the rotating shaft 19;

[0049] A third U-shaped ear seat is fixedly provided at the outer end of the driving shaft 22, and a fourth U-shaped ear seat is fixedly provided at the hinged end of the second rotating sleeve 23. The third U-shaped ear seat and the fourth U-shaped ear seat are cross-distributed and movably hinged through a second cross pin. The second rotating sleeve 23 is hinged to the outer end of the driving shaft 22, and is connected to the driving shaft 22 through the second cross pin, and can rotate with the driving shaft 22, and transmit the power of the driving shaft 22 to the transmission shaft 24.

[0050] The first U-shaped ear seat, the second U-shaped ear seat, the third U-shaped ear seat, and the fourth U-shaped ear seat are respectively arranged at the hinged ends of the rotating shaft 19, the first rotating sleeve 20, the driving shaft 22, and the second rotating sleeve 23, and are cross-distributed and movably hinged with the first cross pin and the second cross pin to achieve flexible connection and power transmission between the components, while allowing a certain angle of swing to adapt to terrain changes;

[0051] A plurality of limit slide bars 26 are fixedly arranged on the outer surface of the rotating shaft 19, and the plurality of limit slide bars 26 are slidably inserted on the inner walls of the first rotating sleeve 20 and the second rotating sleeve 23. The limit slide bars 26 are fixedly arranged on the outer surface of the rotating shaft 19, and are slidably inserted on the inner walls of the first rotating sleeve 20 and the second rotating sleeve 23, so as to limit the relative position between the rotating shaft 19 and the rotating sleeve, thereby ensuring the stability of power transmission, and at the same time enabling the rotating shaft 19 to slide axially in the rotating sleeve to adapt to the displacement caused by terrain changes;

[0052] A pair of buffer springs 25 are fixedly provided at both ends of the rotating shaft 19, and the pair of buffer springs 25 are fixedly inserted in the first rotating sleeve 20 and the second rotating sleeve 23 respectively; the buffer springs 25 are arranged at both ends of the rotating shaft 19, and are fixedly inserted in the first rotating sleeve 20 and the second rotating sleeve 23 respectively, so as to play a buffering role when the terrain changes, reduce the damage to the transmission components caused by vibration, and extend the service life.

[0053] Specifically, the working principle and operation method of the present invention are as follows:

[0054] Step 1: When tobacco is planted in a hilly mountainous area, four servo motors 21 are used to control the corresponding anti-skid wheels 5 to rotate respectively. The motor shaft of the servo motor 21 drives the drive shaft 22 to rotate synchronously. The drive shaft 22 drives the second rotating sleeve 23, the transmission shaft 24, and the first rotating sleeve 20 to rotate synchronously through the second cross pin. The first rotating sleeve 20 drives the rotating shaft 19 and the anti-skid wheels 5 to rotate through the first cross pin. As the anti-skid wheels 5 rotate, the rectangular frame 1 is driven to move on the hilly mountainous area;

[0055] Step 2, when encountering rugged hilly and mountainous areas, under the action of the hinge, the anti-skid wheels 5 drive the V-shaped bracket 15 and the U-shaped bracket 7 to hinge and swing, and drive the piston connecting rod 11 to slide along the piston sleeve 10, so that the tension spring 12 is deformed, and synchronously drives a pair of Z-shaped connecting rods 18 to hinge and swing along the second spherical sleeve 16 and the first spherical sleeve 8, so that the rectangular frame 1 always maintains a stable state.

[0056] The present invention realizes stable walking on complex terrains in hilly and mountainous areas through the coordinated action of various components, has good terrain adaptability and structural stability, and provides reliable power support for tobacco planting.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
