Description

Technical Field

[0001] The utility model belongs to the field of agricultural machinery, and particularly relates to a paddy field wheel. Background Art

[0002] In a paddy field, ploughing is an important task, which can loosen the tillage layer of the soil, optimize the soil structure, and achieve the effect of increasing production and income.

[0003] A paddy field wheel is a relatively common tillage machine, which can be used to plough a paddy field. However, the current paddy field wheel has poor soil crushing efficiency and short service life. On the one hand, most of them use round ribs to support the blades. In such a structure, because the contact area between the round ribs and the blades is small, it is easy to deform when subjected to a large force, resulting in overall deformation and even inability to work. On the other hand, when the entire blade of the paddy field wheel contacts the ground and beats the mud, it is easy to deform when the resistance is large, resulting in poor soil crushing effect.

[0004] Moreover, during the working process of the current paddy field wheel, when the entire blade directly contacts the ground, it will cause large jitters and is prone to the problem of bumps, resulting in poor walking effect.

[0005] Therefore, our company has developed a paddy field wheel that can quickly break the soil, has high soil crushing efficiency, is durable, and has good walking effect. Content of the Utility Model

[0006] In view of the above problems, the utility model designs a paddy field wheel, which includes a cutter barrel. Damping reduction mechanisms are arranged at both ends of the cutter barrel. The damping reduction mechanism includes fixing plates, the fixing plates are connected to the cutter barrel, blades are arranged between the fixing plates, both ends of the blades are connected to the side walls of the fixing plates, the blades include a plurality of soil crushing knives and soil breaking knives, the blades are parallel to the cutter barrel and are distributed outside the cutter barrel, the length of the cutter barrel is less than or equal to the straight-line distance between the fixing plates, and part or all of the soil breaking knives extend out of the outer edge of the fixing plate; the outer edge of the fixing plate is the outermost edge of the fixing plate.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows: By arranging damping reduction mechanisms at both ends of the cutter barrel, it plays a supporting role at both ends of the paddy field wheel, avoiding the contact of the entire blade with the ground, enabling the paddy field wheel to plough smoothly and having a good walking effect. By connecting both ends of the blade to the side walls of the fixing plate, the fixing plate can play a supporting role for the blade, reducing the resistance when the blade contacts the ground.

[0008] The blade consists of a soil-breaking knife and a soil-crushing knife. During tillage, the soil-breaking knife contacts the ground first and can easily break the soil on the ground. Then, the soil-crushing knife contacts the soil again for secondary soil crushing. By breaking the soil first and then crushing it, the resistance between the blade and the ground is small, enabling rapid and efficient soil crushing and simultaneously forming mud quickly and efficiently, reducing the resistance during the process of the blade slapping against the mud.

[0009] Since the blade is parallel to the cutter barrel and distributed on the outside of the cutter barrel, the overall crushing device can perform rotary tillage smoothly. Since the length of the cutter barrel is less than or equal to the straight-line distance between the fixed plates, the cutter barrel is inside the fixed plates, which can reduce the distance at the connection between the paddy field wheel and the power device, further narrowing the gap that cannot be reached by the intermediate-mounted power device, and at the same time preventing weeds from entangling the power connection, improving the rotary tillage effect. By having part or all of the soil-breaking knife extend beyond the edge of the fixed plate, the soil-breaking knife can break the soil first, while preventing the entire blade from directly contacting the ground, reducing the resistance and enabling the paddy field wheel to perform tillage smoothly and efficiently.

[0010] Furthermore, the soil-crushing knife and the soil-breaking knife are arranged at intervals.

[0011] The beneficial effect of adopting the above further technical solution is that by arranging the soil-breaking knife and the soil-crushing knife at intervals, the soil-breaking knife can be distributed among the soil-crushing knives to form a dispersed structure, reducing the resistance during the process of slapping the mud and preventing the situation where the resistance of the entire blade slapping the mud is too large, resulting in blade deformation.

[0012] Furthermore, connection parts are provided at both ends of the blade, and the blade is connected to the fixed plate through the connection parts.

[0013] The beneficial effect of adopting the above further technical solution is that by providing connection parts at both ends of the blade, the blade is connected to the fixed plate, enabling the blade to perform soil crushing inside the rotation space formed by the fixed plate, preventing the resistance during soil crushing from being too large, resulting in jitter, and improving the walking stability of the paddy field wheel.

[0014] Furthermore, the soil-breaking knife is a bent triangular-tooth-shaped blade, the soil-crushing knife is a flat plate, and the included angle between the soil-breaking knife and the soil-crushing knife is 30° - 60°.

[0015] The beneficial effect of adopting the above further technical solution is that by having the soil-breaking knife as a bent triangular-tooth-shaped blade, the soil-breaking knife can break the soil quickly and form a raised triangle, improving the strength of the blade, making the blade more durable and easier to use, and preventing problems such as deformation due to low strength when the blade is flat.

[0016] Furthermore, connection pieces are provided on the fixed plate, the connection pieces are connected to the cutter barrel, and the cutter barrel is arranged between the fixed plates;

[0017] Preferably, the vertical distance between the end of the cutter barrel and the fixing plate is 20 - 50 mm.

[0018] The beneficial effects of adopting the above further technical solution are as follows: By providing a connecting member on the fixing plate, the fixing plate is connected to the cutter barrel; with the vertical distance between the fixing plate and the cutter barrel being 20 - 50 mm, the distance between the two paddy field wheels can be effectively reduced, and at the same time, the transmission mechanism of the gearbox is protected.

[0019] Further, the connecting member is a bent plate, and the bent plate includes a first connecting plate and a second connecting plate, and the included angle between the first connecting plate and the second connecting plate is 60° - 75°.

[0020] The beneficial effects of adopting the above further technical solution are as follows: By the connecting member being a bent plate, the connection strength between the fixing plate and the cutter barrel can be higher. By the first connecting plate being connected to the fixing plate and the second connecting plate being connected to the cutter barrel, and the included angle between the first connecting plate and the second connecting plate being 60° - 75°, a stable support can be formed between the fixing plate and the cutter barrel by the bent plate, further improving the working stability of the paddy field wheel. By the connecting member being inclined with respect to the fixing plate, a recessed space is formed between the end of the fixing plate and the cutter barrel, so that the power transmission part where the gearbox housing is connected to the end of the cutter barrel is located inside the fixing plate, further reducing the gap that cannot be reached in the middle, and at the same time protecting the transmission part where the gearbox is connected to the cutter barrel to avoid weed entanglement.

[0021] Further, the connecting member is a round rib, the connecting member is inclined with respect to the fixing plate, and the included angle between the connecting member and the fixing plate is 60° - 80°.

[0022] The beneficial effects of adopting the above further technical solution are as follows: By providing a connecting member on the fixing plate, the fixing plate is connected to the cutter barrel; by the connecting member being a round rib, the overall paddy field wheel can be made lighter. By the connecting member being inclined with respect to the fixing plate, a recessed space is formed between the end of the fixing plate and the cutter barrel, so that the power transmission part where the gearbox housing is connected to the end of the cutter barrel is located inside the fixing plate, further reducing the gap that cannot be reached in the middle, and at the same time protecting the transmission part where the gearbox is connected to the cutter barrel to avoid weed entanglement.

[0023] Further, the fixing plate can be one or several of a disc, an annular plate, a toothed disc, and a toothed ring.

[0024] The beneficial effects of adopting the above further technical solution are as follows: By the fixing plate being a disc, the two ends of the paddy field wheel can be stably supported. By the support plate being an annulus, the overall paddy field wheel can be made lighter while supporting the paddy field wheel. By the fixing plate being provided as a toothed disc or a toothed ring, the soil breaking effect can be further improved while supporting the paddy field wheel, so as to till the soil faster.

[0025] Furthermore, a fixed plate is provided in the middle of the cutter barrel, and blades are provided between the fixed plate in the middle of the cutter barrel and the fixed plates at both ends of the cutter barrel;

[0026] A connecting member is provided between the fixed plate and the cutter barrel;

[0027] Preferably, the connecting member is one or several of a third connecting plate or a round rib.

[0028] The beneficial effects of adopting the above further technical solution are as follows: By providing a fixed plate in the middle of the cutter barrel and arranging blades between the fixed plate in the middle and the fixed plates at both ends, a double-layer paddy field wheel is formed. By providing a connecting member on the fixed plate in the middle of the cutter barrel, the fixed plate is connected to the cutter barrel. When the connecting member is a third connecting plate, the fixed plate can be stably connected to the middle of the cutter barrel. When the connecting member is a round rib, the fixed plate can be more lightly connected to the middle of the cutter barrel. Description of the Drawings

[0035] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

[0036] This embodiment provides Embodiment 1:

[0037] Please refer to Figures 1-3, A paddy field wheel, including a cutter barrel 1, with resistance reduction mechanisms 2 provided at both ends of the cutter barrel 1. The resistance reduction mechanism 2 includes fixing plates 21, which are connected to the cutter barrel 1. Blades 3 are provided between the fixing plates 21. Both ends of the blade 3 are connected to the side walls of the fixing plates 21. The blade 3 includes a number of soil-breaking knives 31 and soil-piercing knives 32. The blade 3 is parallel to the cutter barrel 1 and is distributed on the outside of the cutter barrel 1, and the blades are distributed along the outer circumference of the cutter barrel 1 in the axial direction. The length of the cutter barrel 1 is less than or equal to the straight-line distance between the fixing plates 21. The soil-piercing knives 32 are distributed radially along the cutter barrel 1, and part or all of the soil-piercing knives 32 protrude beyond the outer edge of the fixing plate 21. The outer edge of the fixing plate 21 is the outermost edge of the fixing plate 21.

[0038] By providing resistance reduction mechanisms 2 at both ends of the cutter barrel 1, it plays a supporting role at both ends of the paddy field wheel, avoiding the entire blade 3 from contacting the ground, enabling the paddy field wheel to plow smoothly with good traveling effect. By connecting both ends of the blade 3 to the side walls of the fixing plates 21, the fixing plates 21 can support the blade 3, reducing the resistance of the blade 3 contacting the ground; since the blade 3 includes two parts, namely soil-breaking knives 31 and soil-piercing knives 32, during the plowing process, the soil-piercing knives 32 first contact the ground and can easily break the soil on the ground, and then the soil-breaking knives 31 contact the soil again for secondary soil breaking. By breaking the soil first and then breaking the soil again, the resistance between the blade 3 and the ground is small, enabling rapid and efficient soil breaking, and at the same time rapidly and efficiently forming mud, reducing the resistance during the process of the blade 3 flapping against the mud; by the blade 3 being parallel to the cutter barrel 1 and distributed on the outside of the cutter barrel 1, it enables the entire breaking device to perform rotary tillage smoothly. By the length of the cutter barrel 1 being less than or equal to the straight-line distance between the fixing plates 21, the cutter barrel 1 is inside the fixing plates 21, which can reduce the distance at the connection between the paddy field wheel and the power device, further reducing the gap that cannot be reached by the intermediate power device, and at the same time avoiding weeds from winding around the power connection, improving the rotary tillage effect; by the soil-piercing knives 32 being distributed radially along the cutter barrel, and part or all of the soil-piercing knives 32 protruding beyond the edge of the fixing plate 21, it enables the soil-piercing knives 32 to break the soil first, and at the same time avoids the entire blade 3 directly contacting the ground, reducing the resistance, enabling the paddy field wheel to plow smoothly and efficiently.

[0039] The soil-piercing knives 32 and the soil-breaking knives 31 are arranged at intervals; by arranging the soil-piercing knives 32 and the soil-breaking knives 31 at intervals, the soil-piercing knives 32 can be distributed among the soil-breaking knives 31 to form a dispersed structure, which can reduce the resistance during the process of flapping the mud, avoiding the situation where the resistance of the entire blade 3 flapping against the mud is too large, resulting in deformation of the blade 3.

[0040] Both ends of the blade 3 are provided with connecting parts 33. The blade is connected to the fixed plate 21 through the connecting parts 33. The edge of the connecting part 33 is flush with the soil-breaking knife 31, and the edge of the connecting part 33 does not exceed the edge of the fixed plate 21. By providing the connecting parts 33 at both ends of the blade 3, the blade 3 is connected to the fixed plate 21. The edge of the connecting part 33 is flush with the soil-breaking knife 31, and the edge of the connecting part 33 does not exceed the edge of the fixed plate 21, so that the soil-breaking knife 31 of the blade breaks soil inside the rotating space formed by the fixed plate 21, avoiding too much resistance during soil-breaking and thus generating a jitter situation, and improving the walking stability of the paddy field wheel.

[0041] The soil-breaking knife 32 is a bent triangular-tooth-shaped blade, and the soil-breaking knife 31 is a flat plate. The included angle between the soil-breaking knife 32 and the soil-breaking knife 31 is 30°-60°. Since the soil-breaking knife 32 is a bent triangular-tooth-shaped blade, the soil-breaking knife 32 can break soil quickly and form a raised triangle, which can improve the strength of the blade 3, make the blade 3 more durable and easier to use, and avoid the problem of deformation due to low strength when the blade 3 is flat.

[0042] The fixed plate 21 is provided with a connecting member 4. The connecting member 4 is connected to the cutter barrel 1. The cutter barrel 1 is arranged between the fixed plates 21. Preferably, the vertical distance between the end of the cutter barrel 1 and the fixed plate 21 is 20-50 mm. By providing the connecting member 4 on the fixed plate 21, the fixed plate 21 is connected to the cutter barrel 1. By the vertical distance between 20-50 mm, the distance between the two paddy field wheels can be effectively reduced, and at the same time, the transmission mechanism of the gearbox is protected.

[0043] The connecting member 4 is a bent plate 41. The bent plate 41 includes a first connecting plate 411 and a second connecting plate 412. The included angle between the first connecting plate 411 and the second connecting plate 412 is 60°-75°. The cutter barrel 1 is arranged between the fixed plates 21. By providing the connecting member 4 on the fixed plate 21, the fixed plate 21 is connected to the cutter barrel 1. By the connecting member 4 being a bent plate 41, the connection strength between the fixed plate 21 and the cutter barrel 1 can be higher. By connecting the first connecting plate 411 to the fixed plate 21 and the second connecting plate 412 to the cutter barrel 1, and the included angle between the first connecting plate 411 and the second connecting plate 412 is 60°-75°, the bent plate 41 can form a stable support between the fixed plate 21 and the cutter barrel 1, further improving the working stability of the paddy field wheel. By the connecting member 4 being inclined with respect to the fixed plate 21, a concave space is formed at the end of the fixed plate 21 and the cutter barrel 1, so that the power transmission part connected to the end of the cutter barrel 1 by the gearbox housing is located inside the fixed plate 21, further reducing the gap that cannot be reached in the middle, and at the same time protecting the transmission part connecting the gearbox and the cutter barrel 1 and avoiding weed entanglement.

[0044] The fixed plate 21 can be one or several of a disc, a ring plate, a toothed disc, and a toothed ring. When the fixed plate 21 is a disc, it can stably support both ends of the paddy field wheel. When the support plate is a ring, it can make the whole paddy field wheel lighter while supporting it. When the fixed plate 21 is set as a toothed disc or a toothed ring, it can further improve the soil-breaking effect while supporting the paddy field wheel, so as to till the soil faster.

[0045] This embodiment provides Embodiment Two:

[0046] Please refer to Figure 4 , a connecting member 4 is arranged on the fixed plate 21. The connecting member 4 is connected to the cutter barrel 1. The connecting member 4 is a round rib 42. The connecting member 4 is inclined to the fixed plate 21, and the included angle between the connecting member 4 and the fixed plate 21 is 60°-80°. The cutter barrel 1 is arranged between the fixed plates 21. By arranging the connecting member 4 on the fixed plate 21, the fixed plate 21 and the cutter barrel 1 are connected. Since the connecting member 4 is a round rib 42, the whole paddy field wheel can be made lighter. Since the connecting member 4 is inclined to the fixed plate 21, a recessed space is formed at the end of the fixed plate 21 and the cutter barrel 1, so that the power transmission part connected to the end of the cutter barrel 1 by the transmission case housing is located inside the fixed plate 21, further reducing the gap that cannot be reached in the middle, and at the same time protecting the transmission part connecting the transmission case and the cutter barrel 1 to avoid weed entanglement.

[0047] This embodiment provides Embodiment Three:

[0048] Please refer to Figure 5 , a fixed plate 21 is further arranged in the middle of the cutter barrel 1. A blade 3 is arranged between the fixed plate 21 in the middle of the cutter barrel 1 and the fixed plates 21 at both ends of the cutter barrel 1. The blades 3 are arranged alternately on the fixed plates 21. A connecting member 4 is arranged between the fixed plate 21 and the cutter barrel 1. By arranging the fixed plate 21 in the middle of the cutter barrel 1 and arranging the blade 3 between it and the fixed plates 21 at both ends, a double-layer paddy field wheel is formed. Since the blades 3 of the double-layer paddy field wheel are arranged alternately, the soil-breaking and soil-crushing effects can be further improved. By arranging the connecting member 4 on the fixed plate 21 in the middle of the cutter barrel 1, the fixed plate 21 and the cutter barrel 1 are connected.

[0049] The connecting member 4 is one or several of a third connecting plate 413 or a round rib 42. When the connecting member 4 is a third connecting plate 413, the fixed plate 21 can be stably connected to the middle of the cutter barrel 1. When the connecting member 4 is a round rib 42, the fixed plate 21 can be more lightly connected to the middle of the cutter barrel 1.
