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

[0044] Embodiment 1:

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

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

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

[0048] When agricultural machinery is in use, the gearbox body 1 may vibrate or even shift due to factors such as uneven ground and mechanical vibration, resulting in transmission failure. The present invention provides a high-stability gearbox for agricultural machinery, wherein the gearbox body 1 is mounted on a stable platform 2, which is mounted on the body of the agricultural machinery. A balance detection unit is used to detect the balance state of the stable platform 2, thereby determining the position state of the gearbox body 1, and the stable platform 2 is adjusted to a horizontal state through an adjustment unit, thereby maintaining an accurate installation position of the gearbox body 1, improving the stability of the operation of the gearbox body 1, and thereby improving the transmission reliability of the agricultural machinery, so that the agricultural machinery can operate efficiently even in complex terrain.

[0049] Embodiment 2:

[0050] like Figure 1 , Figure 2 As shown, based on the above embodiment 1, the adjustment unit includes:

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

[0052] An adjustment seat 12, the adjustment seat 12 is connected to the center of the base 11;

[0053] The sphere 13 is connected to the top of the adjustment seat 12. A groove is provided at the bottom of the stabilizing platform 2. The sphere 13 is rotatably arranged in the groove.

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

[0055] The structure of the adjustment unit adopts a movable stabilizing platform 2, which is installed on the top of the adjustment seat 12, and the two are connected by a ball joint, so that the stabilizing platform 2 can deflect within a preset amplitude range, which is convenient for adjusting the posture of the stabilizing platform 2.

[0056] Embodiment 3:

[0057] like Figure 1 , Figure 2 As shown, based on the above embodiment 2, the balance detection unit includes:

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

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

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

[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, and the detection block 14 on the sphere 13 rotates accordingly and slides in the sensing groove 15. The contact position between the detection block 14 and the pressure sensing sheet changes. When the detection block 14 contacts any sensing point, the sensing point detects a pressure signal. Therefore, the position of the detection block 14 can be determined through the pressure detection results of each sensing point on the pressure sensing sheet, and then the deflection angle and direction of the stable platform 2 can be determined.

[0062] Embodiment 4:

[0063] like Figure 1-Figure 5 As shown, based on the above-mentioned embodiment 2, an adjustment ring 10 is connected to the center of the bottom end of the stabilizing platform 2; the adjustment seat 12 includes:

[0064] A bottom plate 16, 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 of the column 17;

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

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

[0068] The adjusting rod 21 is connected to the outside of the piston 19 and extends out of the boost 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:

[0070] The adjustment ring 10 at the bottom of the stable platform 2 is used in conjunction with the adjustment seat 12; when the stable platform 2 is in a preset balanced state, the ball 13 is located at the center of the sensing slot 15, and the column 17 is perpendicular to the stable platform 2; at this time, the pistons 19 in the multiple boosting tubes 18 are located at the outer ends of the boosting tubes 19, and the multiple adjustment rods 21 are simultaneously abutted against the inner wall of the adjustment ring 10. The number of the adjustment rods 21 is preferably set to three, and the adjustment rods 21 provide multi-directional support for the adjustment ring 10, thereby maintaining the balanced state of the stable platform 2. When the stable platform 2 deflects, the downwardly deflected side, after being compressed by squeezing any one or two adjustment rods 21 through the adjustment ring 10, squeezes the piston 19 to move to the inside of the boosting tube 18, and the unpressurized adjustment rod 21 is separated from the adjustment ring 10 because it is already at the end of the boosting tube 18.

[0071] Embodiment 5:

[0072] like Figure 1-Figure 5 As shown, based on the above-mentioned embodiment 4, the adjustment seat 12 further includes:

[0073] A first pipeline 22, the first pipeline 22 is disposed in the bottom plate 16, and passes through the bottom plate 16 to be connected to 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 connected to the first pipeline 22 , and the side of the second pipeline 23 is connected to the boost pipe 18 .

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

[0076] When the adjustment seat 12 is adjusted, according to the detection result of the balance state of the stable platform 2 by the balance detection unit; 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 boosting pipe 18 through the side of the second pipeline 23, so that the multiple boosting pipes 18 are all filled with gas with sufficient pressure, so that one or two pistons 19 that move toward the inside of the boosting pipe 18 after being pressurized move outward under the action of pressure, and the adjustment rod 21 on this side is extended again, and the adjustment ring 10 is squeezed to rotate upward, pushing the stable platform 2 to reset; the multiple adjustment rods 21 are restored to the state of contacting with the inner wall of the adjustment ring 19 at the same time, so as to realize the adjustment of the angular posture of the stable platform 2, thereby ensuring that the gear box 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 gear box body 1.

[0077] Embodiment 6:

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

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

[0080] When the agricultural machinery generates vibration during operation, the vibration will be transmitted upward from the base 11. Since the lower spring assembly 32 is connected to the base 11, the vibration is first transmitted to the lower spring 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 to the upper spring assembly 31 through the spring 33 to cause it to deform to buffer the vibration, and the spring 33 plays a synergistic buffering role between the two. The auxiliary adjustment unit can buffer and reduce vibration of the stable platform 2 when it is vibrated, and at the same time, use the elasticity of the spring assembly and the spring 33 to assist the stable platform 2 in a small deflection and reset, thereby improving the adaptive adjustment ability of the stable platform 2.

[0081] Embodiment 7:

[0082] like Figure 2 , Figure 6 , Figure 7 As shown, on the basis of the above-mentioned embodiment 6, the upper spring sheet assembly 31 and the lower spring sheet assembly 32 are both configured as a wavy structure, and the curvatures of the two are correspondingly configured, the bottom end of the upper spring sheet assembly 31 is connected to a guide column 34, the lower spring sheet assembly 32 is slidably connected to the guide column 34, and the bottom end of the guide column 34 is slidably connected to the base 11.

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

[0084] The upper spring sheet assembly 31 and the lower spring sheet assembly 32 are both configured as a wave-shaped structure, so that the spring sheet assembly and the stable platform 2 and the base 11 adopt a point contact method to reduce 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 columns 34 are connected to the upper spring sheet assembly 31, and the guide columns 34 slide relative to the lower spring sheet assembly 32 and the base 11, which can maintain the horizontal relative position of the upper spring sheet assembly 31 and the lower spring sheet assembly 32, so that when the upper spring sheet assembly 31 and the lower spring sheet assembly 32 vibrate, they will not move horizontally, that is, the elastic force is concentrated in the vertical direction, thereby improving the vibration reduction effect.

[0085] Embodiment 8:

[0086] like Figure 7 As shown, based on the above-mentioned embodiment 1, the upper spring sheet assembly 31 and the lower spring sheet assembly 32 both include a plurality of spring sheets arranged in a stacked manner, the spring sheets of the upper spring sheet assembly 31 gradually decrease in size from top to bottom, and the spring sheets of the lower spring sheet assembly 32 gradually increase in size from top to bottom, and a plurality of clamps 35 are sleeved on the upper spring sheet assembly 31 and the lower spring sheet assembly 32.

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

[0088] The upper spring sheet assembly 31 and the lower spring sheet assembly 32 are configured as a structure of multiple spring sheets stacked. When subjected to vibration or impact, spring sheets of different sizes from top to bottom will produce elastic deformation in sequence. For example, in the lower spring sheet assembly 32, the size of the spring sheets gradually increases from top to bottom. When subjected to vibration from the machine body, the spring sheets of larger size at the bottom begin to deform first. As the force is transmitted, the spring sheets of smaller size at the top will also deform accordingly. This layered deformation method 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 spring sheets, improve the vibration reduction effect, and help maintain the stability of the gearbox body 1. The clamp 35 fixes the multiple spring sheets in the upper spring sheet assembly 31 and the lower spring sheet assembly 32.

[0089] Embodiment 9:

[0090] like Figure 2 As shown, on the basis of the above-mentioned embodiment 8, a plurality of arc-shaped protrusions 36 are provided at the bottom end of the stabilizing platform 2 , and the arc-shaped protrusions 36 abut against the top end of the upper spring sheet assembly 31 .

[0091] An annular groove 37 is provided at the bottom end of the base 11, and a gear ring 38 is rotatably provided in the annular groove 37. The lower spring assembly 32 and the guide column 34 are connected to the top of the gear ring 38; a gear 39 is meshedly connected to the inner side of the gear 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:

[0093] An arc-shaped protrusion 36 is provided at the bottom of the stabilizing platform 2 . The curvature of the protrusion 36 matches the curvature of the upper spring sheet assembly 31 . The protrusion 36 is located at a position where the upper spring sheet assembly 31 is recessed downward. At this time, the protrusion 36 does not exert force on the upper spring sheet assembly 31 . The balance detection unit detects the balance state of the stable platform and the deflection angle of the stable platform 2 when it is vibrated. When the deflection angle exceeds the preset value, it indicates that the stable platform 2 is subjected to a large vibration in the current section, and the vibration reduction effect of the current auxiliary adjustment unit on the stable platform 2 cannot ensure the balance of the stable platform 2. At this time, the drive motor 40 is started to rotate its output shaft, driving the gear 39 to rotate, and the gear 39 is meshed with the gear ring 38 for transmission. The gear ring 38 drives the upper spring sheet assembly 31 and the lower spring sheet assembly 32 to rotate synchronously, so that the contact position of the protrusion 36 and the upper spring sheet assembly 31 changes. With the rotation, the protrusion 36 gradually moves to the upper protruding position of the upper spring sheet assembly 31, so that the protrusion 36 squeezes the upper spring sheet assembly 31 to deform or move downward as a whole, compresses and stores energy in the spring 33 and the spring sheet, and further compresses the upper spring sheet assembly 31 and the lower spring sheet assembly 32, thereby increasing the overall stiffness of the auxiliary adjustment unit, increasing the elastic force that needs to be overcome when the stable platform 2 is deflected, and improving the balance and stability of the stable platform 2.

[0094] Through the above-mentioned structural design, the auxiliary adjustment unit is set as a stiffness adjustable structure. When the stable platform 2 is subjected to excessive vibration and the deflection angle exceeds the preset value, the stiffness of the spring assembly can be automatically adjusted so that it can maintain sufficient supporting force while reducing vibration, thereby improving the balance and stability of the stable platform 2; it can realize adaptive adjustment in different sections according to the balance detection result, and control the deflection angle of the stable platform 2 within a preset range, effectively adapting to the use environment of agricultural machinery, avoiding the problem of excessive deflection caused by insufficient support stiffness of the stable platform 2, or poor vibration reduction effect caused by excessive support stiffness, thereby improving the stability of the gearbox.
