Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary tiller blade technology, and in particular to a rotary tiller blade with a wear-resistant mechanism. Background Technology
[0002] Rotary tillers are tillage machines used in conjunction with tractors to perform tilling and harrowing operations. They are widely used due to their strong soil-breaking ability and the ability to flatten the soil surface after tilling. They can also chop up stubble buried below the surface, making it easier for seeders to operate and providing a good seedbed for later sowing. The rotary tiller cutter shaft is an important component of the rotary tiller. The rotary tiller cutter shaft assembly includes the cutter shaft and rotary tiller blades. The cutter shaft includes a shaft body and a cutter holder set on the outer circumference of the shaft body. The rotary tiller blades are mounted on the cutter holder of the cutter shaft, and during rotation, they turn the soil over.
[0003] In the prior art, Chinese utility model patent CN222235447U discloses a rotary tiller that facilitates adjustment of tillage depth, including a rotary tiller housing. Lifting connecting plates are slidably installed on both the left and right sides of the rotary tiller housing. A rotating roller is movably installed between the two lifting connecting plates. A lifting assembly is movably installed inside the rotary tiller housing. The lifting assembly includes a threaded rotating rod. A first threaded block and a second threaded block are threadedly connected to the outside of the threaded rotating rod. A first hinge rod and a second hinge rod are respectively hinged to the inside of the first threaded block and the second threaded block. A hinge block is hinged to the bottom end of the first hinge rod and the second hinge rod. A lifting plate is fixedly connected to the bottom of the hinge block.
[0004] In existing technology, by setting up a lifting assembly, the first transmission belt synchronously drives the first rotating shaft to rotate, and the first rotating shaft drives the threaded rod to rotate. Due to the limiting effect of the lifting plate and the hinge block, the first and second threaded blocks are threadedly connected to the outer surface of the threaded rod. When the first and second threaded blocks face corresponding directions, the tilt angle of the first and second hinge rods increases, pushing the lifting plate downwards. When the lifting plate descends, it synchronously drives the lifting connecting plate to descend. During the descent of the lifting connecting plate, it drives the rotating roller and the rotary tiller blades to descend. However, certain problems still exist in actual use. The surface of the plow blades in the above device does not have a protective structure. During operation, the blade part of the rotary tiller blade is in direct contact with hard particles in the soil, such as sand, gravel, or crop residues, and friction occurs. These hard particles will impact and cut the blade surface, causing the blade part to gradually wear down, thereby reducing the service life of the plow blades. Utility Model Content
[0005] The purpose of this invention is to solve the problem that the surface of the plow blade in the above-mentioned devices in the prior art does not have a protective structure, which will directly lead to the gradual wear of the blade part after long-term use, thereby reducing the service life of the plow blade. Therefore, this invention proposes a rotary plow blade with a wear-resistant mechanism.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rotary tiller blade with a wear-resistant mechanism, comprising a rotating shaft and a rotating disk, wherein multiple sets of rotating disks are provided, and multiple rotating disks are uniformly fixedly installed on the outer side of the rotating shaft. Multiple rotary tiller blades are uniformly arranged above and below the center of the rotating shaft, and a glass protective layer is adhered to the upper and lower ends of each rotary tiller blade. Fixed grooves are uniformly opened around the center of the rotating disk, and multiple fixed grooves are staggered with the rotary tiller blades. A wear-resistant component is threadedly connected to the center of each of the multiple fixed grooves. The wear-resistant component includes a base plate and two front blades. The two front blades are respectively fixedly installed above and below the center of one end of the base plate. A second lower screw hole is opened in the center of each of the multiple fixed grooves, and a second upper screw hole is opened in the center of the base plate. The second lower screw hole is connected to the base plate, and a second screw is threadedly connected between the second lower screw hole and the center of the base plate.
[0007] Preferably, each pair of the front blades is located on the same horizontal plane as the rotary tiller blades on one side.
[0008] Preferably, the turntable has a lower screw hole on the upper and lower sides of the center, and one end of each of the rotary tiller blades has an upper screw hole.
[0009] Preferably, the lower screw hole and the upper screw hole are connected, and a screw is threadedly connected to the middle of the lower screw hole and the upper screw hole.
[0010] Preferably, both ends of the rotating shaft are fixedly installed with fixing sleeves, and a limit hole is opened on one side of the middle of the two fixing sleeves.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] 1. In this utility model, a glass protective layer is provided above and below the ends of the rotary tiller blades to provide physical protection. The glass protective layer is made of high-strength glass material, which can effectively isolate the rotary tiller blades from direct contact with hard particles in the soil, thereby reducing blade wear and extending their service life. At the same time, a wear-resistant component is provided in front of each rotary tiller blade. The wear-resistant component consists of a base plate and two front blades. During the tillage process, the front blades can contact the soil first, which can disperse hard particles in the soil and withstand the impact force from the soil, reducing concentrated wear on the rotary tiller blades and slowing down the wear rate of the rotary tiller blades, thereby effectively extending their service life.
[0013] 2. In this utility model, the rotary tiller blade has a special spiral shape, which makes the overall blade height relatively high. The distance between the two front blades that protect it is at the same height as the spiral part at the end of the rotary tiller blade, which can effectively protect the rotary tiller blade and reduce its wear.
[0014] 3. In this utility model, both the rotary tiller blades and the wear-resistant parts are detachable. When the rotary tiller blades or wear-resistant parts are severely worn, they can be directly disassembled and replaced, thereby improving their applicability. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1, as Figure 1-4As shown, this utility model provides a rotary tiller blade with a wear-resistant mechanism, including a rotating shaft 1 and a rotating disk 2. Multiple rotating disks 2 are provided, and are evenly fixedly installed on the outside of the rotating shaft 1. Multiple rotary tiller blades 13 are evenly arranged above and below the center of the rotating shaft 1. A glass protective layer 21 is adhered to the upper and lower ends of each rotary tiller blade 13. Fixing grooves 22 are evenly formed around the center of the rotating disk 2, and the number of fixing grooves 22 is staggered with respect to the rotary tiller blades 13. The middle of each of the multiple fixing slots 22 is threaded with a wear-resistant part 24. The wear-resistant part 24 includes a base plate 25 and two front blades 26. The two front blades 26 are respectively fixedly installed above and below the middle of one end of the base plate 25. The middle of each of the multiple fixing slots 22 is provided with a second lower screw hole 23. The middle of the base plate 25 is provided with a second upper screw hole 27. The second lower screw hole 23 and the base plate 25 are connected. The second lower screw hole 23 and the middle of the base plate 25 are threaded with a second screw 28.
[0023] The specific settings and functions of this embodiment are described in detail below. By providing a glass protective layer 21 above and below the end of the rotary tiller blade 13, which can provide physical protection, the glass protective layer 21 is made of high-strength glass material. It can effectively isolate the rotary tiller blade 13 from direct contact with hard particles in the soil, thereby reducing blade wear and extending its service life. At the same time, a wear-resistant component 24 is provided in front of each rotary tiller blade 13. The wear-resistant component 24 consists of a base plate 25 and two front blades 26. During the tillage process, the front blades 26 can contact the soil first, which can disperse hard particles in the soil, withstand the impact force from the soil, reduce concentrated wear on the rotary tiller blade 13, reduce the wear rate of the rotary tiller blade 13, and thus effectively extend its service life.
[0024] Example 2, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, each pair of front blades 26 are located on the same horizontal plane as the rotary tiller blades 13 on one side. The upper and lower sides of the center of the turntable 2 are provided with lower screw holes 14. One end of each of the multiple rotary tiller blades 13 is provided with an upper screw hole 15. The lower screw holes 14 and the upper screw holes 15 are connected to each other. The middle of the lower screw holes 14 and the upper screw holes 15 is threaded with screws 16. Both ends of the rotating shaft 1 are fixedly installed with fixing sleeves 11. Limiting holes 12 are provided on one side of the middle of the two fixing sleeves 11.
[0025] The overall effect of this embodiment is that by providing a glass protective layer 21 above and below the ends of the rotary tiller blades 13, which provides physical protection, the glass protective layer 21, made of high-strength glass material, can effectively isolate the rotary tiller blades 13 from direct contact with hard particles in the soil, thereby reducing blade wear and extending their service life. Additionally, a wear-resistant component 24 is provided in front of each rotary tiller blade 13. The wear-resistant component 24 consists of a base plate 25 and two front blades 26. During tillage, the front blades 26 can contact the soil first, dispersing hard particles in the soil. The rotary tiller blades 13 are designed to withstand the impact of soil, reducing concentrated wear and slowing down their wear rate, thus effectively extending their service life. The rotary tiller blades 13 have a unique, spiral shape, resulting in a relatively high overall blade height. The distance between the two front blades 26 protecting them is at the same height as the spiral end of the rotary tiller blades 13, effectively protecting them and reducing wear. Both the rotary tiller blades 13 and the wear-resistant parts 24 are detachable, allowing for direct removal and replacement when either is severely worn, thereby improving their applicability.
[0026] The device's usage and working principle are as follows: A glass protective layer 21, made of high-strength glass, is provided above and below the ends of the rotary tiller blades 13 to provide physical protection. This effectively isolates the rotary tiller blades 13 from direct contact with hard particles in the soil, reducing blade wear and extending their service life. Additionally, a wear-resistant component 24 is installed in front of each rotary tiller blade 13. This component consists of a base plate 25 and two front blades 26. During tillage, the front blades 26 contact the soil first, dispersing hard particles and bearing the impact force, reducing concentrated wear on the rotary tiller blades 13 and lowering their wear rate. The rotary tiller blades 13 have a unique, rotating shape, resulting in a relatively high overall blade height. The distance between the two front blades 26 protecting them is at the same height as the rotating end of the rotary tiller blade 13, effectively protecting the blades and reducing wear.
[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
