Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery, specifically relating to a support mechanism, a paddy field wheel, and agricultural machinery. Background Technology

[0002] In agricultural paddy field operations, agricultural machinery needs to be equipped with paddy field wheels to perform rotary tillage in wet and soft soil environments. When paddy field wheels move in paddy fields, they are prone to getting stuck in the muddy soil, making it difficult to move and thus greatly reducing the efficiency of rotary tillage. In addition, there are a lot of weeds, straw and other debris in the paddy field operation environment. The connection between the output shaft of the gearbox and the paddy field wheel cutter barrel is easily entangled by weeds. Once the debris is entangled, the output shaft will not run smoothly and the power transmission will be blocked. This will not only cause the agricultural machinery to stop and cause equipment failure, but may also cause the paddy field wheel to sink further due to staying in the same position for a long time. To address these issues, our company has developed a support mechanism, paddy field wheel, and agricultural machinery to solve the problems of getting stuck in the soil and being difficult to move, as well as the blade connection being easily entangled by weeds. Utility Model Content

[0003] To address the aforementioned problems, this utility model designs a support mechanism, including a support plate and a support ring. The support plate has a cutter cylinder mounting part at its center, which is a through hole or groove. The support ring is disposed opposite to the support plate, and a plurality of crawling plates are disposed between the support plate and the support ring. The support ring is connected to the support plate through the plurality of crawling plates.

[0004] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting several crawling plates between the support ring and the support plate, the axial width of the support mechanism is increased, which can increase the contact area between the support mechanism and the soil, preventing the paddy field wheel from sinking, thus facilitating the movement of the paddy field wheel; by setting crawling plates and support ring, weeds can also be prevented from getting tangled on the output shaft connected to the support plate, improving the rotary tillage efficiency of the paddy field wheel; the support ring is connected to the support plate through several crawling plates, and the support ring strengthens the crawling plates, preventing deformation of the crawling plates, forming a protective ring on the outer periphery of the output shaft, preventing weeds from getting tangled on the output shaft through the gaps between the crawling plates, and further preventing weeds from getting tangled on the output shaft, thereby further improving the movement efficiency of the paddy field wheel.

[0005] Furthermore, the support plate is circular, one end of the crawling plate is close to the center of the support plate, and the other end extends towards the edge of the support plate and is bent. The crawling plate can extend to the edge of the support plate.

[0006] The beneficial effects of adopting the above-mentioned further technical solution are as follows: by having one end of the crawler plate close to the center of the support plate and the other end of the crawler plate extending to the edge of the support plate, a protective barrier can be formed on the outer periphery of the output shaft, while the crawler plate assists the support plate in moving, thereby improving the crawling force of the support mechanism. Furthermore, a reinforcing plate is provided at the bend of the crawling board; and / or the crawling board is a bent plate; The bending angle of the crawling plate is 10°-170°, and the crawling plate is set perpendicular to the support plate; And / or the edge of the support plate is provided with a plurality of crawling teeth, and the bending direction of the crawling plate is the same as the direction of the crawling teeth of the support plate.

[0007] Several crawling plates are evenly distributed around the circumference of the support plate, and the bending direction of several crawling plates is arranged in the same direction along the circumference of the support plate, and the bending direction is in the same direction as the rotation tangent of the support plate.

[0008] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: By setting reinforcing plates at the bends of the crawling plates, the strength of the crawling plates can be improved, further preventing deformation and enhancing the walking ability of the paddy field wheel; by making the crawling plates into bent plates, the bending and deformation resistance of the crawling plates can be enhanced. During rotary tillage operations, the crawling plates need to withstand soil resistance and their own torque. The bending structure can better distribute stress and prevent damage due to insufficient strength. By evenly distributing the crawling plates around the support plate circumferentially, with the bends of the crawling plates facing the same direction, the crawling plates are evenly distributed around the support plate in a circular pattern, ensuring uniformity of the crawling plates. The bending of the crawler plate allows for more efficient soil contact, preventing the paddy field wheel from sinking. The bending angle of the crawler plate creates a more "engaged" contact with the soil, increasing friction and thus stabilizing grip and reducing slippage. Furthermore, the two bent surfaces contact the soil sequentially during rotation, extending the instantaneous contact time. This allows the soil's reaction force on the crawler plate to continuously accumulate, generating greater traction and providing an upward force to the paddy field wheel, offsetting some of the sinking tendency and maintaining a relatively stable operating height, thereby improving the efficiency of rotary tillage. By setting the crawling plate perpendicular to the support plate, the axial width of the support plate can be increased, thereby increasing the contact area between the support mechanism and the soil and increasing the crawling force of the support mechanism. By aligning the crawling teeth and crawling plate in the same direction, the bending force-bearing surface of the crawling plate aligns with the tooth orientation of the toothed disc, creating a synergistic force-bearing structure between the crawling plate and the crawling teeth. This double engagement between the bending force-bearing surface of the crawling plate and the soil-gripping surface of the crawling teeth enhances the support mechanism's grip and traction on the soil, reduces slippage, and ensures that the soil resistance borne by both is aligned in the same direction. This avoids localized stress concentration caused by misalignment of force directions, further strengthening the structural stability of the support mechanism.

[0009] Furthermore, the crawling plate is provided with a first clamping platform and a second clamping platform, which are arranged in a stepped manner and extend radially along the support plate. The support ring is disposed on the first clamping platform. The support ring is arranged parallel to the support plate.

[0010] The beneficial effects of adopting the above-mentioned further technical solution are as follows: the crawling plate is provided with a first clamping platform and a second clamping platform, which are arranged in a stepped manner, so that the crawling plate is clamped to the outer periphery of the output shaft of the gearbox, preventing weeds from getting tangled on the output shaft of the gearbox. At the same time, the support ring is set on the outer periphery of the output shaft of the gearbox to further prevent weeds from getting tangled.

[0011] Furthermore, the support ring is one or more of a circular ring or a polygonal ring.

[0012] The beneficial effects of adopting the above-mentioned further technical solution are as follows: by using a circular or polygonal ring as the support ring, the strength of several crawling plates can be improved, while preventing weeds from getting tangled on the gearbox output shaft. It can also ensure the connection stability between the support ring and the gearbox, enabling power to be transmitted to the paddy field wheel efficiently and stably, and providing a certain degree of protection for the gearbox output shaft. Furthermore, it can prevent weeds, straw, etc. from getting tangled on the output shaft, avoiding the output shaft from running poorly, power transmission from being obstructed, or even causing equipment failure due to debris getting tangled.

[0013] Furthermore, both the crawling plate and the support ring are disposed on the outer periphery of the cutter barrel mounting portion.

[0014] The beneficial effects of adopting the above-mentioned further technical solution are as follows: by setting both the crawling plate and the support ring on the outer periphery of the cutter barrel mounting part, the crawling plate and the support ring are positioned on the outer periphery of the connection between the output shaft of the gearbox and the cutter barrel, thus protecting the output shaft of the gearbox and effectively preventing weeds from getting tangled on the output shaft of the gearbox.

[0015] Furthermore, the support plate is provided with a plurality of weight-reducing holes, and the crawling plate is disposed between the weight-reducing holes.

[0016] The beneficial effects of adopting the above-mentioned further technical solution are as follows: by reducing the weight of the support mechanism through the weight-reducing holes, the resistance of paddy field operation is reduced, while ensuring that the crawling plate is assembled on the rigid body of the support plate, ensuring the stability of the force, and ensuring that the support plate body can provide stable support when the crawling plate is subjected to soil resistance, and will not cause local deformation due to the hollowing; the "strip-shaped solid area" formed by adjacent weight-reducing holes provides a linear assembly surface for the crawling plate, so that the force of the crawling plate can be evenly transmitted to the center of the support plate along the solid area, which can reduce stress concentration, and further improve the overall deformation resistance in conjunction with the bending structure of the crawling plate.

[0017] Furthermore, the support plate is provided with a plurality of blade mounting holes, and the crawling plate is disposed between the blade mounting holes.

[0018] The beneficial effects of adopting the above-mentioned further technical solution are as follows: the blade mounting holes are used to assemble the paddy field wheel blades to realize the rotary tillage and soil pulverization function; the crawling plate is used for anti-sinking and walking. The two are alternately arranged on the support plate, so that when the paddy field wheel is working, the soil pulverization function of the blades and the gripping and anti-sinking function of the crawling plate can work together to improve the overall work efficiency; setting the crawling plate in the solid area of ​​the support plate between the blade mounting holes can avoid the structural strength gap caused by the mounting holes. The rigid body of the support plate without holes can provide a stable assembly foundation for the crawling plate, ensuring the structural stability of the crawling plate when subjected to soil resistance and torque. At the same time, it also avoids the overall rigidity reduction of the support plate caused by multiple holes.

[0019] A paddy field wheel, characterized in that: it includes the above-mentioned support mechanism, and further includes a cutter barrel and blades, wherein the cutter barrel is connected to a cutter barrel mounting part on at least two support plates; The blade is connected to blade mounting holes on at least two support plates, and the crawling plate and support ring are disposed on the side of the support plate away from the blade.

[0020] The beneficial effects of adopting the above-mentioned further technical solution are as follows: by connecting the cutter barrel and blades to the support plate respectively, rotary tillage is carried out under the support of the support plate. A crawling plate is set on the side of the support plate away from the blades, thereby preventing the paddy field wheel from sinking.

[0021] An agricultural machine includes the aforementioned paddy field wheel and a gearbox. The gearbox includes a gearbox housing and a power output shaft. A boss is provided on the gearbox housing, and the power output shaft extends out of the gearbox housing from the boss. The power output shaft is connected to a cutter barrel, and a crawler plate is disposed outside the power output shaft. A first clamping platform and a second clamping platform cooperate with the boss of the gearbox housing to clamp the machine, and a support ring is sleeved outside the boss.

[0022] The beneficial effects of adopting the above-mentioned further technical solution are as follows: By connecting the power output shaft of the gearbox to the cutter barrel of the paddy field wheel, the power of the gearbox is transmitted to the paddy field wheel, thereby driving the paddy field wheel to perform rotary tillage. The crawling plate is set outside the power output shaft to prevent weeds from getting tangled on the power output shaft of the cutter barrel. The support ring is set outside the boss to further protect the power output shaft of the gearbox. The clamping platform one and clamping platform two cooperate with the gearbox to clamp, thereby protecting the area around the power output shaft that extends out of the gearbox housing, so that the power can be transmitted to the paddy field wheel efficiently and stably.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model.

[0025] Example 1, please refer to Figure 1-4 : This embodiment provides a support mechanism, including a support plate 1 and a support ring 3. A blade mounting part 11 is provided at the center of the support plate 1. The support plate 1 and the support ring 3 are arranged opposite each other. A plurality of crawling plates 2 are arranged between the support ring 3 and the support plate 1. The support ring 3 is connected to the support plate 1 through the crawling plates 2. By providing a plurality of crawling plates 2 between the support ring 3 and the support plate 1, the axial width of the support mechanism is increased, which increases the contact area between the support mechanism and the soil, preventing the paddy field wheel from sinking, thus facilitating the movement of the paddy field wheel. The crawling plates 2 and the support ring 3 also prevent weeds from tangling on the output shaft connected to the support plate 1, improving the rotary tillage efficiency of the paddy field wheel. The support ring 3 is connected to the support plate 1 through the crawling plates 2, which strengthens the crawling plates 2, preventing deformation and further preventing weeds from tangling on the output shaft, thereby further improving the movement efficiency of the paddy field wheel.

[0026] The support plate 1 is circular. One end of the crawling plate 2 is close to the center of the support plate 1, and the other end extends towards the edge of the support plate 1 and is bent. The crawling plate 2 can extend to the edge of the support plate. By having one end of the crawling plate 2 close to the center of the support plate 1 and the other end extending to the edge of the support plate 1, a protective barrier can be formed on the outer periphery of the output shaft. At the same time, the crawling plate 2 assists the support plate in moving, improving the crawling force of the support mechanism. The crawling plate 2 is a bent plate; the bending angle of the crawling plate 2 is 10°-170°, and the crawling plate 2 is perpendicular to the support plate 1; and / or the edge of the support plate 1 is provided with a plurality of crawling teeth, and the bending direction of the crawling plate 2 is the same as the direction of the crawling teeth of the support plate 1. A plurality of the crawling plates 2 are evenly distributed around the circumference of the support plate 1, and the bending direction of the plurality of the crawling plates 2 is arranged in the same direction along the circumference of the support plate 1, and the bending direction is in the same direction as the rotation tangent of the support plate 1. By using a bent crawler plate 2, the bending and deformation resistance of the crawler plate 2 is enhanced. During rotary tillage operations, the crawler plate 2 needs to withstand soil resistance and its own torque. The bent structure can better distribute stress and avoid damage due to insufficient strength. The crawler plate 2 is evenly distributed around the support plate 1, with the bending direction of the crawler plate 2 being the same. This ensures that the crawler plate 2 is evenly distributed around the support plate 1, allowing for uniform contact with the soil and preventing the paddy field wheel from sinking. When rotating, the bent crawler plate 2 can more efficiently cut into the soil and generate thrust. On the one hand, the bending angle makes the contact between the crawler plate and the soil more "engaged," increasing friction and thus stabilizing grip and reducing slippage. On the other hand, during rotation, the two bent surfaces will contact the soil successively, prolonging the instantaneous contact time with the soil, and the reaction force of the soil on the crawler plate 2 can be sustained. The continuous superposition generates greater traction, providing an upward force component for the paddy field wheel, offsetting some of the sinking trend, maintaining a relatively stable operating height for the agricultural machinery, and improving the efficiency of rotary tillage. By setting the crawling plate 2 perpendicular to the support plate 1, the axial width of the support plate 1 can be increased, thereby increasing the contact area between the support mechanism and the soil and increasing the crawling force of the support mechanism. By having the crawling teeth and crawling plate 2 face the same direction, the bending force-bearing surface of the crawling plate 2 is aligned with the tooth orientation of the toothed disc, forming a cooperative force-bearing structure between the crawling plate 2 and the crawling teeth. This creates a double engagement between the bending force-bearing surface of the crawling plate 2 and the soil-gripping surface of the crawling teeth, improving the support mechanism's grip and traction on the soil, reducing slippage, and unifying the direction of soil resistance borne by both, avoiding local stress concentration caused by misalignment of force directions, and further enhancing the structural stability of the support mechanism.

[0027] The crawling plate 2 is provided with a first clamping platform 21 and a second clamping platform 22, which are arranged in a stepped manner and extend radially along the support plate 1. The support ring 3 is disposed on the first clamping platform 21; the support ring 3 is arranged parallel to the support plate 1. By providing the first clamping platform 21 and the second clamping platform 22, the crawling plate 2 is clamped to the outer periphery of the output shaft of the gearbox 6, preventing weeds from getting entangled on the output shaft of the gearbox 6. At the same time, the support ring 3 is disposed on the outer periphery of the output shaft of the gearbox 6 to further prevent weeds from getting entangled.

[0028] The support ring 3 can be one or more of a circular ring or a polygonal ring. By using a circular or polygonal ring for the support ring 3, the strength of several crawling plates 2 can be improved, while preventing weeds from getting tangled on the output shaft of the gearbox 6. It can also ensure the connection stability between the support ring 3 and the gearbox 6, so that power can be transmitted to the paddy field wheel efficiently and stably, and it can play a certain protective role for the output shaft of the gearbox 6. It can also prevent weeds, straw and other debris from getting tangled on the output shaft, avoiding the output shaft from running poorly, power transmission from being blocked, or even causing equipment failure due to debris getting tangled.

[0029] Both the crawling plate 2 and the support ring 3 are disposed on the outer periphery of the cutter barrel mounting part 11. By disposing of the crawling plate 2 and the support ring 3 on the outer periphery of the connection between the output shaft of the gearbox and the cutter barrel, the output shaft of the gearbox is protected, effectively preventing weeds from getting tangled on the output shaft of the gearbox.

[0030] Both the crawling plate 2 and the support ring 3 are disposed on the outer periphery of the cutter barrel mounting part 11. The cutter barrel mounting part 11 is disposed at the center of the support plate 1, and the crawling plate 2 and the support ring 3 are disposed on the outer periphery of the cutter barrel mounting part 11. Thus, the crawling plate 2 and the support ring 3 are disposed on the outer periphery of the connection between the output shaft of the gearbox 6 and the cutter barrel 4, thereby protecting the output shaft of the gearbox 6 and effectively preventing weeds from getting tangled on the output shaft of the gearbox 6.

[0031] The support plate 1 is provided with a plurality of weight-reducing holes 12, and the crawling plate 2 is disposed between the weight-reducing holes 12. The weight-reducing holes 12 reduce the overall weight of the support mechanism, thereby reducing the resistance of paddy field operations, while ensuring that the crawling plate 2 is assembled on the rigid body of the support plate 1, ensuring the stability of the force, and ensuring that the support plate 1 can provide stable support when the crawling plate 2 is subjected to soil resistance, without local deformation caused by the hollowing out; the "strip-shaped solid area" formed by adjacent weight-reducing holes 12 provides a linear assembly surface for the crawling plate 2, so that the force on the crawling plate 2 can be evenly transmitted to the center of the support plate 1 along the solid area, which can reduce stress concentration, and together with the bending structure of the crawling plate 2, further improve the overall deformation resistance.

[0032] The support plate 1 has several blade mounting holes 13, and the crawling plate 2 is disposed between the blade mounting holes 13. The blade mounting holes 13 are used to assemble the paddy field wheel blades 5 to realize the rotary tillage and soil breaking function; the crawling plate 2 is used for anti-sinking and walking. The two are alternately arranged on the support plate 1, so that when the paddy field wheel is working, the soil breaking function of the blades 5 and the gripping and anti-sinking function of the crawling plate 2 work together to improve the overall working efficiency. By placing the crawling plate 2 in the solid area of ​​the support plate 1 between the blade mounting holes 13, the structural strength gap caused by the mounting holes can be avoided. The rigid body of the support plate 1 without holes provides a stable assembly base for the crawling plate 2, ensuring the structural stability of the crawling plate 2 when subjected to soil resistance and torque. At the same time, it also avoids the overall rigidity reduction of the support plate 1 due to multiple holes.

[0033] This embodiment also provides a paddy field wheel using the above-mentioned support mechanism, including the support mechanism described above, and further including a cutter barrel 4 and blades 5. The cutter barrel 4 is connected to the cutter barrel mounting part 11 on at least two support plates 1; the blades 5 are connected to the blade mounting holes 13 on at least two support plates 1, and the crawling plate 2 and support ring 3 are arranged on the side of the support plate 1 away from the blades 5. By connecting the cutter barrel 4 and blades 5 to the support plates 1 respectively, rotary tillage is performed under the support of the support plates 1. The crawling plate 2 is provided on the side of the support plate 1 away from the blades 5, thereby preventing the paddy field wheel from sinking.

The gearbox includes a gearbox housing 61 and a power output shaft 62. A boss 611 is provided on the gearbox housing 61, and the power output shaft 62 extends out of the gearbox housing 61 from the boss 611. The power output shaft 62 is connected to a cutter barrel 4. The crawling plate 2 and the support ring 3 are disposed outside the power output shaft. The first clamping platform 21 and the second clamping platform 22 cooperate with the boss 611 of the gearbox housing 61 for clamping. The support ring 3 is sleeved outside the boss 611. The power output shaft 62 of the gearbox is connected to the cutter barrel of the paddy field wheel, transmitting the power of the gearbox to the paddy field wheel, thereby driving the paddy field wheel to perform rotary tillage. The crawling plate 2 is set outside the power output shaft 62 to prevent weeds from getting tangled on the power output shaft 62 of the cutter barrel. The support ring 3 is set outside the boss 611 to further protect the power output shaft 62 of the gearbox. The clamping platform 1 21 and clamping platform 22 cooperate with the gearbox to clamp the power output shaft 62, thereby protecting the area around the power output shaft 62 that extends out of the gearbox housing, so that the power can be transmitted to the paddy field wheel efficiently and stably.
