Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology and relates to a paddy field wheel. Background Technology

[0002] In paddy fields, tilling is an important task that loosens the topsoil, optimizes soil structure, and increases yield and income. Paddy field wheels are a common type of tillage machinery used for tilling paddy fields. For example, a Chinese patent discloses a paddy field wheel structure [authorization announcement number CN213426819U], including a bushing, a collar, connecting rods, a fixing ring, a scraper, a connecting plate, a triangular plate, a positioning insert plate, a rotating shaft, and a flat key. The collar has an inner hole, and the outer side of the bushing is adapted to the inner hole of the collar, allowing the bushing to pass through the inner hole. The collar is connected to the bushing by multiple screws. Multiple connecting rods are located on the side of the collar shaft, with the outer sides of the connecting rods welded to the fixing rings. The fixing rings are evenly distributed on the upper part of the bushing. The scraper is welded to the fixing ring. The upper part of the connecting plate is connected to the scraper, and the lower part of the connecting plate is connected to the fixing ring. The lower part of the triangular plate is welded to the scraper, and the triangular plate has through holes and is symmetrically arranged on the scraper.

[0003] The scrapers of the aforementioned paddy field wheel extend radially outward. When the scrapers beat the mud, they have a large contact area with the mud and experience greater resistance. Furthermore, the multiple scrapers are spaced apart along the circumference of the paddy field wheel, creating blind spots in mud beating and failing to effectively break up the mud. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a paddy field wheel that can break up mud more finely.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A paddy field paddlewheel includes an axle, a support structure mounted on the axle, and multiple blades mounted on the support structure. The blades are arranged in a circular array along the centerline of the axle. Each blade has multiple blades evenly distributed along its length, with some blades on adjacent blades staggered. By having multiple blades on each blade, and with some blades on adjacent blades staggered, the blades cut into the soil during operation. The different cutting positions of the blades on different blades reduce blind spots in mud breaking and effectively break up the mud.

[0007] In the aforementioned paddy field wheel, the blade includes a plate-shaped blade body and a cutting edge located on the side of the blade body. The angle between the plane containing the blade body and the plane perpendicular to the center line of the wheel axle is 0° or an acute angle. When rotating, the cutting edge is located on the front side of the blade body.

[0008] Because the blade is tilted relative to the plane perpendicular to the center line of the wheel axle, it can further separate the mud after cutting into the soil, thus breaking up the mud.

[0009] In the aforementioned paddy field reel, the blade body is arc-shaped, and the cutting edge is located on the convex edge of the blade body.

[0010] In the aforementioned paddy field wheel, multiple blades located on the same blade plate are parallel to each other.

[0011] In the aforementioned paddy field wheel, the number of blades is even.

[0012] In the aforementioned paddy field wheel, the blades on the odd-numbered blades are inclined toward one end of the wheel axle, while the blades on the even-numbered blades are inclined toward the other end of the wheel axle.

[0013] That is, the blades on two adjacent blades are tilted in different directions. When they cut into the mud, they can separate the mud in different directions, thereby improving the grip.

[0014] In the aforementioned paddy field wheel, the blades are arranged at an angle relative to the wheel axle.

[0015] In the aforementioned paddy field reel, the blade has a flange located on the front side of the blade. The flange protects the blade and also prevents it from getting tangled with weeds.

[0016] In the aforementioned paddy field wheel, the support structure includes several support rings coaxially arranged with the wheel axle and connecting rods connecting the support rings and the wheel axle. The support rings are evenly distributed along the length of the wheel axle. The aforementioned blades are connected to the support rings, and each support ring is supported by at least three circumferentially evenly arranged connecting rods.

[0017] In the aforementioned paddy field wheel, the axle is equipped with several connecting flanges that correspond one-to-one with the support rings, and the side of the connecting rod is connected to the corresponding connecting flange. The connecting flanges strengthen the connection between the connecting rod and the axle, thus improving the connection strength.

[0018] Compared with existing technologies, this paddy field wheel has the following advantages: due to the multiple circumferentially evenly distributed blades, it does not sink when working on muddy fields and moves smoothly; the flanges on the blades not only protect the connection between the blades and the blades but also prevent weeds from getting tangled; the blades are welded to the blades, and the blades have sharp cutting edges, which break up the mud more finely and can effectively remove weeds from the field; the different inclination directions of several blades on two adjacent blades can effectively improve the grip.

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1 The paddy field wheel shown includes a hexagonal prism axle 1, a support structure on the axle 1, and six blades 2 extending approximately along the length of the axle 1 and inclined relative to the axle 1 on the support structure. The six blades 2 are arranged in a circular array along the centerline of the axle 1.

[0025] like Figure 1-3 As shown, the blade plate 2 has a flange 20 located on the front side of the blade. The flange 20 protects the blade and also prevents grass from getting tangled.

[0026] There are an even number of leaf plates 2. In this embodiment, as shown... Figure 1-3 As shown, there are six blades 2, and each blade 2 has multiple blades evenly distributed along its length. The blades located in odd-numbered positions have more blades than those located in even-numbered positions. Specifically, as... Figure 1 As shown, the number of blades on the odd-numbered blades 2 is 4, and the number of blades on the even-numbered blades 2 is 3. The multiple blades on two adjacent blades 2 are arranged alternately.

[0027] like Figure 1-3 As shown, multiple blades located on the same blade plate 2 are parallel to each other.

[0028] like Figure 2 As shown, the blades on the odd-numbered blades 2 are inclined towards one end of the axle 1, while the blades on the even-numbered blades 2 are inclined towards the other end of the axle 1. That is, the blades on two adjacent blades 2 are inclined in different directions. When they cut into the mud, they can separate the mud in different directions, thereby improving the grip.

[0029] like Figure 1 and Figure 3As shown, the blade includes a plate-shaped blade body 31 and a cutting edge 32 located on the side of the blade body 31. The angle between the plane where the blade body 31 is located and the plane perpendicular to the center line of the wheel axle 1 is 15°. When rotating, the cutting edge 32 is located on the front side of the blade body 31.

[0030] Since the blade body 31 is inclined relative to the plane perpendicular to the center line of the wheel axle 1, the blade can further separate the mud after cutting into the soil, thereby breaking up the mud.

[0031] like Figure 3 As shown, the blade body 31 is arc-shaped, and the cutting edge 32 is located on the convex edge of the blade body 31.

[0032] like Figure 1 As shown, the support structure includes three support rings 4 coaxially arranged with the wheel axle 1 and connecting rods 5 connecting the support rings 4 and the wheel axle 1. The three support rings 4 are evenly distributed along the length direction of the wheel axle 1. The blade 2 is connected to the support rings 4. Each support ring 4 is supported by three circumferentially evenly arranged connecting rods 5.

[0033] To improve connection strength, such as Figure 1 and Figure 3 As shown, the axle 1 is provided with three connecting flanges 6 that correspond one-to-one with the support ring 4, and the side of the connecting rod 5 is connected to the corresponding connecting flange 6.

[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
