[0043] It should be understood that the terms such as "having", "comprising", and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0044] Embodiment 1:

[0045] As Figure 1 shown, the present invention provides a high-stability gearbox for agricultural machinery, including:

[0046] The gearbox body 1 and the stable platform 2, the gearbox body 1 is installed on the stable platform 2, a balance detection unit and an adjustment unit are arranged on the stable platform 2, the balance detection unit is arranged at the center of the stable platform 2 for detecting the balance state of the stable platform 2; the adjustment unit is arranged below the stable platform 2 for adjusting the attitude of the stable platform 2.

[0047] The working principle and beneficial effects of the above technical solution are as follows:

[0048] When the agricultural machinery is in use, due to factors such as uneven ground and mechanical vibration, the gearbox body 1 will vibrate or even shift, resulting in transmission failure. The present invention provides a high-stability gearbox for agricultural machinery. The gearbox body 1 is installed on the stable platform 2, and the stable platform 2 is installed on the body of the agricultural machinery. The balance detection unit is used to detect the balance state of the stable platform 2, and then determine the position state of the gearbox body 1. The stable platform 2 is adjusted to a horizontal state through the adjustment unit, so as to keep the installation position of the gearbox body 1 accurate, improve the stability of the operation of the gearbox body 1, and further improve the transmission reliability of the agricultural machinery, enabling the agricultural machinery to operate efficiently even in complex terrains.

[0049] Embodiment 2:

[0050] As Figure 1 、 Figure 2 shown, on the basis of the above Embodiment 1, the adjustment unit includes:

[0051] The base 11, and the base 11 is installed on the body of the agricultural machinery;

[0052] The adjusting seat 12, and the adjusting seat 12 is connected to the center of the base 11;

[0053] The sphere 13, and the sphere 13 is connected to the top of the adjusting seat 12. A groove is provided at the bottom end of the stable platform 2, and the sphere 13 is rotatably arranged in the groove.

[0054] The working principle and beneficial effects of the above technical solution are as follows:

[0055] The structure of the adjustment unit adopts the movable stable platform 2. The stable platform 2 is installed on the top of the adjusting seat 12, and the two are connected through the ball pair, enabling the stable platform 2 to deflect within a preset range, facilitating the adjustment of the attitude of the stable platform 2.

[0056] Embodiment 3:

[0057] As Figure 1 、 Figure 2 shown, on the basis of the above Embodiment 2, the balance detection unit includes:

[0058] The detection block 14, and the detection block 14 is connected to the top of the sphere 13;

[0059] The induction groove 15, which is arranged in the stable platform 2 and communicated with the top end of the groove. A pressure induction sheet is connected to the top end of the induction groove 15, and a plurality of induction points are evenly distributed on the pressure induction sheet. The detection block 14 is slidably arranged in the induction groove 15 and contacts the pressure induction sheet.

[0060] The working principle and beneficial effects of the above technical solution are as follows:

[0061] When the balance detection unit is in use, when the stable platform 2 deflects, the sphere 13 rotates in the groove of the stable platform 2. The detection block 14 on the sphere 13 rotates accordingly and slides in the induction groove 15. The contact position between the detection block 14 and the pressure induction sheet changes. When the detection block 14 contacts any induction point position, this induction point detects a pressure signal. Therefore, through the pressure detection results of each induction point on the pressure induction sheet, the position of the detection block 14 can be determined, and further the deflection angle and direction of the stable platform 2 can be determined.

[0062] Example 4:

[0063] As Figures 1 - 5 shown, on the basis of the above Example 2, an adjusting ring 10 is connected to the center of the bottom end of the stable platform 2; the adjusting seat 12 includes:

[0064] A bottom plate 16, and the bottom plate 16 is connected to the center of the base 11;

[0065] A column 17, the column 17 is connected to the center of the bottom plate 16, and the sphere 13 is connected to the top end of the column 17;

[0066] A pressurizing pipe 18, and a plurality of pressurizing pipes 18 are horizontally connected to the middle part of the column 17 and are uniformly arranged along the circumferential direction;

[0067] A piston 19, and the piston 19 is slidably connected in the pressurizing pipe 18;

[0068] An adjusting rod 21, the adjusting rod 21 is connected to the outside of the piston 19 and extends out of the pressurizing pipe 18, and the end of the adjusting rod 21 abuts against the inner wall of the adjusting ring 10.

[0069] The working principle and beneficial effects of the above technical solution are as follows:

[0070] The adjusting ring 10 at the bottom end of the stable platform 2 is used in cooperation with the adjusting seat 12; when the stable platform 2 is in the preset balanced state, the sphere 13 is located at the center of the induction groove 15, and the column 17 is perpendicular to the stable platform 2; at this time, the pistons 19 in the plurality of pressurizing pipes 18 are located at the outer ends of the pressurizing pipes 19, and the plurality of adjusting rods 21 simultaneously abut against the inner wall of the adjusting ring 10. The number of the adjusting rods 21 is preferably set to three, and the adjusting rods 21 support the adjusting ring 10 in multiple directions, thereby maintaining the balanced state of the stable platform 2. When the stable platform 2 deflects, on the side that deflects downward, when any one or two of the adjusting rods 21 are compressed by the adjusting ring 10, the piston 19 is squeezed to move inward in the pressurizing pipe 18, and the uncompressed adjusting rods 21 are separated from the adjusting ring 10 because they are already located at the end positions of the pressurizing pipes 18.

[0071] Example 5:

[0072] As Figures 1 - 5 shown, on the basis of the above-mentioned Embodiment 4, the adjusting seat 12 further includes:

[0073] The first pipeline 22 is arranged in the bottom plate 16 and passes through the bottom plate 16 to be connected with the air pump;

[0074] The second pipeline 23 is arranged at the center of the column 17. The bottom end of the second pipeline 23 is communicated with the first pipeline 22, and the side surface of the second pipeline 23 is communicated with the pressurizing pipeline 18.

[0075] The working principle and beneficial effects of the above technical solution are as follows:

[0076] When the adjusting seat 12 is adjusted, according to the detection result of the balance detection unit on the balance state of the stable platform 2; the air pump is started to inflate the first pipeline 22, and the gas enters the second pipeline 23 through the first pipeline 22, and then enters the surrounding pressurizing pipeline 18 through the side surface of the second pipeline 23, so that sufficient pressure gas is introduced into each of the plurality of pressurizing pipelines 18, so that one or two pistons 19 that move inward toward the inner side of the pressurizing pipeline 18 after being pressed move outward under the action of the pressure, extend the adjusting rod 21 on this side again, and squeeze the adjusting ring 10 to rotate upward, pushing the stable platform 2 to reset; so that the plurality of adjusting rods 21 are restored to the state of simultaneously contacting the inner wall of the adjusting ring 19, realizing the adjustment of the angular attitude of the stable platform 2, and further ensuring that the gearbox body 1 can be maintained at the preset installation position, reducing the possibility of transmission failure, and improving the stability of the operation of the gearbox body 1.

[0077] Embodiment 6:

[0078] As Figure 2 、 Figure 6 、 Figure 7 shown, on the basis of the above-mentioned Embodiment 5, an auxiliary adjustment unit is arranged on the base 11. The auxiliary adjustment unit includes: an upper elastic sheet assembly 31 and a lower elastic sheet assembly 32. The upper elastic sheet assembly 31 is supported at the bottom end of the stable platform 2, the lower elastic sheet assembly 32 is connected to the base 11, a spring 33 is connected between the upper elastic sheet assembly 31 and the lower elastic sheet assembly 32, and the upper elastic sheet assembly 31 and the lower elastic sheet assembly 32 are made of elastic materials.

[0079] The working principle and beneficial effects of the above technical solution are as follows:

[0080] When the agricultural machinery generates vibration during operation, the vibration will conduct upward from the base 11. Since the lower elastic sheet assembly 32 is connected to the base 11, the vibration is first transmitted to the lower elastic sheet assembly 32, causing it to undergo a certain degree of elastic deformation and absorb part of the vibration energy. At the same time, the vibration continues to be transmitted upward through the spring 33 to the upper elastic sheet assembly 31 to cause deformation to buffer the vibration, and the spring 33 plays a collaborative buffering role between the two. The auxiliary adjustment unit can buffer and damp the vibration of the stable platform 2 when it is subjected to vibration, and at the same time, utilize the elasticity of the elastic sheet assembly and the spring 33 to assist the stable platform 2 to deflect and reset slightly, improving the adaptive adjustment ability of the stable platform 2.

[0081] Embodiment 7:

[0082] As Figure 2 , Figure 6 , Figure 7 shown, on the basis of the above Embodiment 6, both the upper elastic sheet assembly 31 and the lower elastic sheet assembly 32 are set as wavy structures, and their arcs are correspondingly set. A guide post 34 is connected to the bottom end of the upper elastic sheet assembly 31, and the lower elastic sheet assembly 32 is slidably connected to the guide post 34, and the bottom end of the guide post 34 is slidably connected to the base 11.

[0083] The working principle and beneficial effects of the above technical solution are as follows:

[0084] Both the upper elastic sheet assembly 31 and the lower elastic sheet assembly 32 are set as wavy structures, so that the elastic sheet assembly contacts the stable platform 2 and the base 11 in a point contact manner, reducing the transmission of vibration; at the same time, the multi-point support method helps to maintain the balance of the stable platform 2. A plurality of guide posts 34 are connected to the upper elastic sheet assembly 31, and the guide posts 34 slide relative to the lower elastic sheet assembly 32 and the base 11, which can maintain the horizontal relative position of the upper elastic sheet assembly 31 and the lower elastic sheet assembly 32, so that when the upper elastic sheet assembly 31 and the lower elastic sheet assembly 32 vibrate, there will be no horizontal lateral displacement, that is, the elastic force is concentrated in the vertical direction, improving the damping effect.

[0085] Embodiment 8:

[0086] As Figure 7 shown, on the basis of the above Embodiment 1, both the upper elastic sheet assembly 31 and the lower elastic sheet assembly 32 include a plurality of elastic sheets stacked on top of each other. The elastic sheets of the upper elastic sheet assembly 31 gradually decrease in size from top to bottom, and the elastic sheets of the lower elastic sheet assembly 32 gradually increase in size from top to bottom. A plurality of clamps 35 are sleeved on both the upper elastic sheet assembly 31 and the lower elastic sheet assembly 32.

[0087] The working principle and beneficial effects of the above technical solution are as follows:

[0088] The upper shrapnel assembly 31 and the lower shrapnel assembly 32 are arranged in a structure with multiple shrapnels stacked. When subjected to vibration or impact, the shrapnels of different sizes from top to bottom will sequentially undergo elastic deformation. In the lower shrapnel assembly 32, for example, the size of the shrapnels gradually increases from top to bottom. When subjected to vibration from the machine body, the larger-sized shrapnels at the bottom start to deform first, and as the force is transmitted, the smaller-sized shrapnels above will also undergo corresponding deformation. This way of layered deformation can buffer vibrations of different intensities and frequencies in layers, absorb the vibration energy layer by layer and convert it into the elastic potential energy of the shrapnels, improve the vibration damping effect, and help maintain the stability of the gearbox body 1. The clamp 35 fixes the multiple shrapnels in the upper shrapnel assembly 31 and the lower shrapnel assembly 32.

[0089] Embodiment 9:

[0090] As Figure 2 shown, on the basis of the above Embodiment 8, a plurality of arc-shaped protrusions 36 are provided at the bottom end of the stable platform 2, and the arc-shaped protrusions 36 abut against the top end of the upper shrapnel assembly 31.

[0091] A circular groove 37 is provided at the bottom end of the base 11, a toothed ring 38 is rotatably arranged in the circular groove 37, and the lower shrapnel assembly 32 and the guide post 34 are connected to the top end of the toothed ring 38; a gear 39 is meshed and connected to the inner side of the toothed ring 38, and a driving motor 40 is installed in the base 11, and the output end of the driving motor 40 is connected to the rotating shaft of the gear 39.

[0092] The working principle and beneficial effects of the above technical solution are as follows:

[0093] An arc-shaped protrusion 36 is provided at the bottom end of the stable platform 2. The radian of the protrusion 36 is adapted to the radian of the upper shrapnel assembly 31, and the protrusion 36 is located at the position where the upper shrapnel assembly 31 is recessed downward. At this time, the protrusion 36 does not exert a force on the upper shrapnel assembly 31. The balance detection unit detects the balance state of the stable platform and the deflection angle of the stable platform 2 when subjected to vibration; when the deflection angle exceeds the preset value, it indicates that the vibration received by the stable platform 2 on the current road section is relatively large, and the vibration damping effect of the current auxiliary adjustment unit cannot ensure the balance of the stable platform 2; at this time, the driving motor 40 is started to make its output shaft rotate, driving the gear 39 to rotate. The gear 39 is meshed with the toothed ring 38 for transmission, and the toothed ring 38 drives the upper shrapnel assembly 31 and the lower shrapnel assembly 32 to rotate synchronously, so that the contact position between the protrusion 36 and the upper shrapnel assembly 31 changes; as it rotates, the protrusion 36 gradually moves towards the upward protruding position of the upper shrapnel assembly 31, causing the protrusion 36 to squeeze the upper shrapnel assembly 31 to deform or move downward as a whole, compress and store energy in the spring 33 and the shrapnels, further compress the upper shrapnel assembly 31 and the lower shrapnel assembly 32, thereby improving the overall stiffness of the auxiliary adjustment unit, increasing the elastic force that needs to be overcome when the stable platform 2 deflects, and improving the balance and stability of the stable platform 2.

[0094] Through the above structural design, the auxiliary adjustment unit is set as a structure with adjustable stiffness. When the stable platform 2 is vibrated too much and the deflection angle exceeds the preset value, it can automatically adjust the stiffness of the elastic sheet assembly, so that it can maintain sufficient supporting force while damping vibration, improving the balance and stability of the stable platform 2; it can realize adaptive adjustment on different road sections according to the balance detection result, control the deflectable angle of the stable platform 2 within the preset range, effectively adapt to the use environment of agricultural machinery, avoid the problem that the stable platform 2 has insufficient supporting stiffness and excessive deflection, or the damping effect is poor due to excessive supporting stiffness, and improve the use stability of the gearbox.
