Description

Technical Field

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

[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] The paddy field wheel blade is the main working part that contacts the ground and directly breaks the soil during the ploughing work. When the entire flat blade of the paddy field wheel contacts the ground to break the soil, the resistance is large, and it is easy to deform over time.

[0004] In addition, the mud blocks in the mud rolled up by the blade are cut out by the flat blade. When the mud blocks are too large, the entire blade hitting the mud is subject to a large resistance, and it is also easy to deform over time.

[0005] Therefore, our company has developed a paddy field wheel blade and a paddy field wheel that can quickly break the soil, have high soil-breaking efficiency, and are durable. Content of the Utility Model

[0037] To make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model.

[0038] This embodiment provides Embodiment 1

[0039] Please refer to Figure 1, in view of the above problems, the utility model designs a paddy field wheel blade, which includes a plurality of soil-breaking knives 1 and soil-crushing knives 2. The soil-breaking knives 1 and the soil-crushing knives 2 are arranged at intervals. A stabilizing member 4 is provided at the bottom of the soil-breaking knives 1 and the soil-crushing knives 2. Connecting members 3 are respectively provided at both ends of the paddy field wheel blade. By providing a plurality of soil-breaking knives 1 and soil-crushing knives 2, the soil-breaking knives 1 can quickly break the soil on the ground first, and then the soil-crushing knives 2 crush the broken soil, thereby reducing the resistance of the blade in contact with the soil, enabling rapid and efficient soil crushing, quickly forming mud, and avoiding the situation where the entire flat blade has a large contact resistance with the soil. By arranging the soil-breaking knives 1 and the soil-crushing knives 2 at intervals, the soil-breaking knives 1 and the soil-crushing knives 2 can be dispersed, so that the dispersed blade structure beats the mud, reducing the resistance during the beating process, avoiding the situation where the whole blade is beaten in the mud and suffers from a large resistance and deformation, enabling the blade to quickly break the soil, having high soil-crushing efficiency and being durable. By providing a stabilizing member 4 at the bottom of the soil-breaking knives 1 and the soil-crushing knives 2, the bottom of the soil-crushing knives 2 and the soil-breaking knives 1 is reinforced, making the overall strength of the blade higher. By respectively providing connecting members 3 at both ends of the paddy field wheel blade, the two ends of the paddy field wheel blade are connected to the paddy field wheel, and at the same time, the stability of both ends of the paddy field wheel blade can be improved, enhancing the overall strength of the paddy field wheel blade and making the paddy field wheel blade more durable.

[0040] Please refer to Figure 1-2 , the soil-breaking knife 1 includes a first side surface 11 and a second side surface 12, and the first side surface 11 and the second side surface 12 are arranged alternately;

[0041] Preferably, a soil-breaking part 13 is provided at the front ends of the first side surface 11 and the second side surface 12, and the tip of the soil-breaking part 13 is an arc;

[0042] More preferably, both the first side surface 11 and the second side surface 12 are quadrilateral plates, and the first side surface 11 and the second side surface 12 form a triangular protrusion. Since the soil-breaking knife 1 includes the first side surface 11 and the second side surface 12, and the first side surface 11 and the second side surface 12 are arranged alternately, a ridge bulging to one side is formed, so that the soil-breaking knife 1 as a whole forms a stable triangular structure, which can increase the overall strength of the soil-crushing knife 2, thereby enhancing the overall strength of the blade, making the blade more durable and easier to use, and avoiding the problem that the blade is flat and has low strength and is prone to deformation. By providing the soil-breaking part 13, a tip for quickly breaking the soil is formed. Since the tip of the soil-breaking part 13 is an arc, the resistance of the soil-breaking knife 1 in contact with the ground can be reduced, and a certain buffering force can be added when the soil-breaking knife 1 contacts the ground, making the blade break the soil more smoothly. Since both the first side surface 11 and the second side surface 12 are quadrilateral, and a triangular protrusion is formed on one side of the first side surface 11 and the second side surface 12, and the two side surfaces are staggered, a triangular bulge is formed, forming a stable soil-breaking structure.

The soil-breaking portion 13 is provided on the front side of the soil-breaking portion 21, and the included angle between the first side surface 11 or the second side surface 12 and the soil-breaking knife 2 is 30° - 60°. By arranging the soil-breaking knife 2 between the side surfaces of the two soil-breaking knives 1, a structure in which the soil-breaking knives 1 and the soil-breaking knife 2 are dispersedly arranged is formed, which can reduce the resistance during the process of beating the mud. By providing the soil-breaking portion 21 on the soil-breaking knife 2, the soil can be broken. By arranging the soil-breaking portion 13 on the front side of the soil-breaking portion 21, the soil-breaking portion 13 can first contact the ground for soil-breaking, and then the soil-breaking portion 21 can break the soil after soil-breaking.

[0045] The soil-breaking knife 1 is a bent triangular-tooth-shaped blade, and the soil-breaking knife 2 is a flat plate. By the soil-breaking knife 1 being a bent triangular-tooth-shaped blade, the soil-breaking knife 1 can break the soil quickly with small resistance. By the soil-breaking knife 2 being a flat plate, the soil after soil-breaking can be broken. The soil-breaking knife 1 and the soil-breaking knife 2 are connected to each other to form a blade with high strength and capable of quickly and efficiently ploughing.

Preferably, the edge of the connector 3 is flush with the edge of the soil-breaking knife 2. By providing the connectors 3 at both ends of the paddy field wheel blade, the blade is connected to the paddy field wheel. By providing the mounting holes 31 on the connectors 3, bolts can pass through the mounting holes 31 to connect with the paddy field wheel. By the edge of the connector 3 being flush with the edge of the soil-breaking knife 2, the connector 3 can be located at the rear side of the soil-breaking knife 1, avoiding the situation that the connector 3 first contacts the ground and the connector 3 is detached due to too large impact force.

Since the stabilizing member 4 is perpendicularly arranged with respect to the bottoms of the soil-breaking knife 1 and the soil-crushing knife 2, further reinforcement is formed at the rear side of the triangular shape where the soil-breaking knife 1 bulges and at the rear side of the soil-crushing knife 2, increasing the overall strength of the blade, making the blade light and more durable at the same time.

[0048] The stabilizing member 4 includes a triangular base 41 and a rectangular base 42, and the triangular base 41 is connected to the rectangular base 42; the shape of the triangular base 41 matches the shape of the bottom of the soil-breaking knife 1; since the stabilizing member 4 includes the triangular base 41 and the shape of the triangular base 41 matches the shape of the bottom of the soil-breaking knife 1, the two are joined to form a stable and high-strength soil-breaking structure. Since the stabilizing member 4 includes the rectangular base 42, the bottoms of the soil-breaking knife 1 and the soil-crushing knife 2 are connected into a whole, improving the stability between the soil-breaking knife 1 and the soil-crushing knife 2, and thus improving the overall strength of the blade of the paddy field wheel.

[0049] Clamping portions 43 are provided at both ends of the stabilizing member 4; preferably, the clamping portions 43 are perpendicularly arranged with respect to the connecting member; by providing the clamping portions 43 at both ends of the stabilizing member 4, a clamping space is formed between the clamping portions 43 and the connecting member 3, so that the blade is clamped on the paddy field wheel, further strengthening the stability of the connection between the blade and the paddy field wheel; since the clamping portions 43 are perpendicularly arranged with respect to the connecting member, the clamping space matches the shape of the paddy field wheel more, thus further improving the connection strength of the blade of the paddy field wheel.
