Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to an agricultural water field wheel. Background Art

[0002] Paddy fields refer to cultivated land that requires sufficient water supply within a certain planting area. Since paddy fields need to be immersed in irrigation water for a long time during planting, the organic matter in paddy field soil decomposes slowly under the condition of flooding and lack of oxygen, resulting in a high level of humus in the soil. Based on this, paddy field soil is relatively sticky, and there are high requirements for soil turning operations in paddy field cultivation.

[0003] The Chinese patent application number 2020221614220 discloses a paddy field wheel structure for agricultural machinery, including a sleeve, a collar, a connecting rod, a fixed ring, a scraper, and a connecting plate. The sleeve has an inner hole of the sleeve, the outer side of the sleeve is adapted to the inner hole of the sleeve, the sleeve passes through the inner hole of the sleeve, the sleeve is connected to the sleeve by multiple screws, the sleeve shaft side has multiple connecting rods, the outer side of the connecting rod is welded to the fixed ring, the fixed ring is evenly distributed on the upper part of the sleeve, the scraper is welded to the fixed ring, and the upper part of the connecting plate is connected to the scraper. Among them, the sleeve, the connecting rod and the fixed ring together form a blade mounting body for mounting the scraper (also known as a blade). When setting, the various components need to be fixed by welding, the welding workload is large, and the production efficiency is low.

[0004] The Chinese patent with application number 202023079342.7 discloses a kind of anti-grass entanglement paddy field wheel, including a paddy field wheel support structure, a wheel axle and blades. The paddy field wheel support structure includes a support plate body, on which a protrusion protruding from the side of the support plate body is fixed; a mud hole is provided on the support plate body, and the protrusion is fixed at least one of the edge of the mud hole and the edge of the support plate body; a plurality of connecting parts are provided on the edge of the support plate body, and the blades are connected to the connecting parts; the wheel axle is fixed on the support plate body. This application can effectively solve the problem of large welding workload and low production efficiency in the support structure of the paddy field wheel. However, the mud hole opened on the above-mentioned support plate will reduce the strength of the plate next to the mud hole. After long-term use, the two adjacent mud holes are prone to deformation and fracture. At the same time, a groove is formed between the protrusion on the mud hole and the protrusion set on the support plate body, which is easy to form mud accumulation here, affecting subsequent use. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide an agricultural paddy field wheel to solve the problem that the blade mounting disc of the existing paddy field wheel is prone to breakage and deformation after long-term use, and is prone to soil accumulation, affecting subsequent use.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] An agricultural water field wheel includes an axle, at least two blade mounting discs are sleeved at intervals in the axial direction of the axle, and a plurality of blades are fixed circumferentially between each two adjacent blade mounting discs and on the outer edges of the blade mounting discs; the blade mounting disc includes a metal disc with an axle sleeve hole in the middle, and a plurality of weight-reducing holes are distributed circumferentially on the metal disc with the axle sleeve hole as the center, and the weight-reducing holes and the outer edges of the metal disc are bent to one side to form inner and outer flanges respectively; on the metal disc, between each two adjacent weight-reducing holes, there are outwardly protruding reinforcing ribs, and the reinforcing ribs are convex ribs formed after stamping, and at least one water pipe introduction hole is also provided between one of the inner and outer flanges or between each inner and outer flanges, and the water pipe introduction hole is arranged close to the convex ribs. In this way, the blades are directly fixed on the metal disc, and the metal disc is integrally formed, with low manufacturing cost and high production efficiency. After the convex ribs are set next to the weight-reducing holes, the strength of the metal disc next to the weight-reducing holes can be effectively increased. The convex ribs are formed by stamping, which has high processing efficiency. The convex ribs are set near the weight-reducing holes, which can effectively increase the strength of the plate between the two weight-reducing holes, so that it will not break or deform. After the water pipe introduction hole is set between the inner flange and the outer flange, after the soil is accumulated, the water pipe can be inserted into the water pipe introduction hole to flush the soil at that position to avoid soil accumulation.

[0008] Furthermore, the reinforcing rib is T-shaped, consisting of a radially arranged vertical rib and a transverse rib located at the outer end of the vertical rib. The inner end of the vertical rib extends to the axle sleeve hole, and the outer end is arranged close to the outer edge of the metal disc. The transverse rib is arranged perpendicular to the vertical rib, or in an arc shape. In this way, the vertical ribs in the convex rib can strengthen the radial structural strength between the two weight-reducing holes, and the transverse ribs arranged can further strengthen the circumferential strength of this position. After the transverse rib is set as an arc structure, the transverse rib is parallel to the outer edge of the metal disc and spans between the outer sides of the weight-reducing holes, which can increase the strength of this position.

[0009] Further, a water pipe introduction hole is provided on the left and right sides of each convex rib. In this way, after two water pipe introduction holes are provided at each location, it can be effectively ensured that after the water pipe is inserted, each position can be quickly flushed.

[0010] Furthermore, the depth of the inner flange is less than the depth of the outer flange. In this way, there is a depth difference between the inner flange and the outer flange, thereby reducing the accumulation of soil while ensuring strength.

[0011] Furthermore, a clamping groove is provided at one end of each blade connected to the metal disc and at the corresponding position of the blade and each metal disc, and the blade is clamped and connected to the outer flange of the metal disc through the clamping groove and fixed to the outer flange by welding. In this way, after the blade is clamped to the outer flange through the clamping groove, it is fixedly connected to the outer flange by welding, which is convenient for welding processing. At the same time, it can effectively increase the connection area between the blade and the metal disc, and because the inner side of the blade is clamped on the outer flange, the stability between the metal disc and the blade is more stable and the connection strength is better.

[0012] Furthermore, a plurality of blade reinforcement plates corresponding to the blades are fixedly mounted on the outer flange of each metal disc, and the outer ends of the blade reinforcement plates are closely attached to the blades and are welded and fixed to the inner sides of the blades. In this way, the blade reinforcement plates can form a triangular connection with the blades and the metal discs, further strengthening the support for the blades and further improving the connection strength of the blades.

[0013] Furthermore, the middle part of the blades are all convex outwards, forming a folded plate structure, and at least one ground-breaking angle is formed by stamping on the outer side of each blade. In this way, the ground-breaking angle is formed by stamping, which can reduce the processing workload and improve the forming quality compared with the existing welding fixing method.

[0014] Furthermore, a plurality of protrusions formed by stamping are provided on each blade. In this way, the reinforcing ribs stamped on the blade can further increase the strength of the blade on blades of the same thickness.

[0015] Furthermore, the blade mounting disks are provided with three, the blades are provided with at least two circles, and the blades in two adjacent circles are staggered. In this way, after the blades are staggered, the length of the blades is set shorter, the force is smaller, and the service life of the blades is improved. At the same time, under the same cultivated area, the force on each blade is more balanced, and the service life is longer. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1-Figure 3As shown, the agricultural water field wheel provided in this embodiment includes an axle 1, at least two blade mounting discs 2 are sleeved at intervals in the axial direction of the axle 1, and a plurality of blades 3 are fixed circumferentially on the outer edge of the blade mounting disc 2 between every two adjacent blade mounting discs 2; the blade mounting disc 2 includes a metal disc 21 with an axle sleeve hole in the middle, and a plurality of weight-reducing holes 22 are distributed circumferentially on the metal disc 21 with the axle sleeve hole as the center, and the weight-reducing holes 22 and the outer edges of the metal disc 21 are bent to one side to form an inner flange 23 and an outer flange 24, respectively; on the metal disc 21, between every two adjacent weight-reducing holes 22, a reinforcing rib 25 protruding outward 32 is provided, and the reinforcing rib 25 is a convex rib formed after stamping, and at least one water pipe introduction hole 27 is also provided between one of the inner flanges 23 and the outer flange 24 or between each inner flange 23 and the outer flange 24, and the water pipe introduction hole 27 is arranged close to the convex rib. In this way, the blade 3 is directly fixed on the metal disc 21, and the metal disc 21 is formed in one piece, with low manufacturing cost and high production efficiency. After the convex rib is set next to the weight-reducing hole 22, the strength of the metal disc 21 next to the weight-reducing hole 22 can be effectively increased, and the convex rib is formed by stamping, which has high processing efficiency, and the convex rib is set near the weight-reducing hole 22, which can effectively increase the strength of the plate between the two weight-reducing holes 22, so that it will not break or deform. After the water pipe introduction hole 27 is set between the inner flange 23 and the outer flange 24, after the soil is accumulated, the water pipe can be inserted into the water pipe introduction hole 27 to flush the soil at this position to avoid soil accumulation.

[0022] Furthermore, the reinforcing rib 25 is T-shaped, consisting of a radially arranged vertical rib and a transverse rib located at the outer end of the vertical rib. The inner end of the vertical rib extends to the axle sleeve hole, and the outer end is arranged close to the outer edge of the metal disc 21. The transverse rib is arranged perpendicular to the vertical rib, or in an arc shape. Of course, in the specific implementation, it can also be stamped into other shapes, which are not described in detail here. In this way, the vertical ribs in the convex rib can strengthen the radial structural strength between the two weight-reducing holes 22, and the transverse ribs arranged can further strengthen the circumferential strength of this position. After the transverse rib is set to an arc structure, the transverse rib is parallel to the outer edge of the metal disc 21, and spans between the outer sides of the weight-reducing holes 22, which can increase the strength of this position.

[0023] Further, a water pipe introduction hole 27 is provided on the left and right sides of each reinforcing rib 25. The water pipe introduction hole is circular and the diameter can be set as required. In this way, after two water pipe introduction holes 27 are provided at each location, it can effectively ensure that each location can be quickly flushed after the water pipe is inserted.

[0024] Further, in this embodiment, the depth of each inner flange 23 is less than the depth of the outer flange 24. In this way, there is a depth difference between the inner flange 23 and the outer flange 24, so that on the basis of ensuring strength, the accumulation of soil can also be reduced.

[0025] Furthermore, a clamping groove 31 is provided at one end of each blade 3 connected to the metal disc 21 and at the corresponding position of the blade 3 and each metal disc 21, and the blade 3 is clamped and connected to the outer flange 24 of the metal disc 21 through the clamping groove 31, and is fixed to the outer flange 24 by welding. In this way, after the blade 3 is clamped to the outer flange 24 through the clamping groove, it is fixedly connected to the outer flange 24 by welding, which is convenient for welding processing. At the same time, it can effectively increase the connection area between the blade 3 and the metal disc 21, and because the inner side of the blade 3 is clamped on the outer flange 24, the stability between the metal disc 21 and the blade 3 is more stable and the connection strength is better.

[0026] Furthermore, a plurality of blade reinforcement plates 26 corresponding to the blades 3 are fixedly mounted on the outer flange 24 of each metal disc 21, and the outer ends of the blade reinforcement plates 26 are in close contact with the blades 3 (i.e., the outer ends are inclined), and are welded and fixed to the inner sides of the blades 3. In this way, the blade reinforcement plates 26 can form a triangular connection with the blades 3 and the metal disc 21, further strengthening the support for the blades 3, so that the connection strength of the blades 3 is further improved.

[0027] Furthermore, the middle of the blades 3 are all protruded outward 32, which is a folded plate structure, and at least one ground-breaking angle 33 is formed by stamping on the outer side of each blade 3. In this way, the ground-breaking angle 33 is formed by stamping, which can reduce the processing workload and improve the molding quality compared with the existing welding fixation method.

[0028] Furthermore, each blade 3 is provided with a plurality of protrusions 32 formed by stamping, and the protrusions 32 include long strip-shaped protrusions arranged along the length direction of the blade 3, and also include an H-shaped protrusion arranged between two ground-breaking angles 33. In this way, the protrusions 32 stamped on the blade 3 can further increase the strength of the blade 3 on the blade 3 of the same thickness.

[0029] like Figure 1 As shown, in this embodiment, three blade mounting plates 2 are provided, and at least two circles of blades 3 are provided, and two adjacent circles of blades 3 are staggered. In this way, after the blades 3 are staggered, the length of the blades 3 is set shorter and the force is smaller, which is beneficial to increase the service life of the blades 3. At the same time, under the same farming area, each blade 3 is more evenly stressed and has a longer service life.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the utility model without departing from the purpose and scope of the technical solution of the utility model should be included in the scope of the claims of the utility model.
