Description

Technical Field

[0001] The utility model relates to the field of plowshare teeth, in particular to a plowshare tooth for agricultural machinery operation. Background Art

[0002] The plow is a farming tool used for tilling, mainly used to turn over and loosen the soil in preparation for sowing. Its history can be traced back to ancient times. With the advancement of technology, the shape and function of the plow have continued to evolve. Modern plows are mostly pulled by tractors, and their efficiency has been significantly improved; the plowshare teeth are part of the plow, which can break up hard soil clods and make the soil finer, which is convenient for subsequent tillage. The broken soil is easier to be turned over by the plow wall, improving the quality of turning over the soil; therefore, the plowshare teeth play an important role in breaking up the soil, reducing resistance, improving the turning over effect and protecting the plowshare, which is crucial to improving the efficiency and quality of tillage.

[0003] The patent with publication date of November 29, 2024 and announcement number CN222073798U discloses a working tooth for an agricultural machinery plowshare, including a tooth head body with a long strip structure, wherein the tooth head body with a long strip structure is composed of an integrally formed working part and an assembly part, and the working part is inclined upward on the side away from the assembly part to form an upturned working head, on which a hard alloy layer is welded, and the other side of the working part is connected to the assembly part through an arc-shaped transition edge, and a welding strip wear-resistant layer is welded on the arc-shaped transition edge, and the middle part of the top surface of the assembly part is recessed inward to form an elongated assembly groove, and at least one assembly through hole is arranged in the assembly groove, and a limiting groove with a "J-shaped" structure is arranged at the end of one side of the bottom surface of the assembly part away from the working part, and the limiting groove with the "J-shaped" structure is used to facilitate the insertion of agricultural machinery and play a limiting role, and at least one positioning hole is arranged in the limiting groove, and the assembly part is positioned through the positioning hole to play a double fixing role.

[0004] The soil conditions in different seasons at different latitudes and longitudes vary greatly. The design of a single plowshare tooth cannot fully adapt to the needs of different soil types, resulting in poor results under certain soil conditions. The above solution changes the original pure alloy steel working teeth / plowshares to the current working surface using a high-strength and high-wear-resistant hard alloy layer. At the same time, the working part (the rear area of ​​the working surface) adopts high-strength and high-wear-resistant hard welding rod surfacing technology to form a surfacing layer, which enhances the strength and wear resistance of the surface, protects the tooth head body together, greatly improves the product life and work efficiency, and reduces the installation and disassembly of the working teeth / plowshares. The assembly part (handle) is fixed with two positioning holes and a limit card slot to make it stable and firm. The edge of the bolt hole is designed with a crescent-shaped high-strength and high-wear-resistant hard alloy to protect the bolts, prevent the bolts from wearing out prematurely and causing the teeth / plowshares to fall off, and improve the service life of the product. However, this solution does not take into account the poor adaptability of the plowshare teeth to different soil conditions and crop requirements, and it is difficult to meet the diversified farming needs. Users need to replace different types of plowshare teeth according to different conditions, which increases the complexity and cost of operation.

[0005] Therefore be necessary to provide a kind of agricultural machinery operation plowshare tooth. Utility Model Content

[0022] Based on this, in order to improve the poor adaptability of the plowshare teeth in the related technology to different soil conditions and crop requirements, which is difficult to meet the diversified farming needs, users need to replace different types of plowshare teeth according to different conditions, which increases the operation complexity and cost. The embodiment of the present application provides the following solution.

[0023] Please also read Figure 1-Figure 3, including a main body base 1, a replaceable tooth tip 2, an angle adjustment mechanism 3 and a fixing strip 4, the replaceable tooth tip 2 is provided with a replacement groove, the replaceable tooth tip 2 is sleeved on the main body base 1, the replacement groove is provided with a fixing through hole, the main body base 1 is provided with a square hole, the fixing through hole is connected with the square hole, the fixing strip 4 passes through the square hole and the fixing through hole, and the replaceable tooth tip 2 is fixed on the main body base 1, the angle adjustment mechanism 3 is arranged on the main body base 1, and is used to adjust the angle between the replaceable tooth tip 2 and the ground, and the replaceable tooth tip 2 includes but is not limited to a sharp cone tooth, a wave tooth and a flat shovel tooth.

[0024] In this way, by replacing different replaceable tooth tips 2, different soil types can be adapted. The pointed cone teeth are suitable for hard soil and have strong penetration; the wavy teeth are suitable for sandy soil and can reduce dust; the flat shovel teeth are suitable for sticky soil to prevent clay from sticking. In the process of replacing the replaceable tooth tip 2, first pull out the fixing bar 4 from the square hole and the fixed through hole, replace the old replaceable tooth tip 2, and then align the replacement groove of the new replaceable tooth tip 2 with the protruding part of the main body base 1, and put the replaceable tooth tip 2 on the main body base 1. At this time, the square hole is connected to the fixed through hole, and the fixed through hole is used. The fixed bar 4 is inserted into the square hole and the fixed through hole to fix the replaceable tooth tip 2 on the main body base 1. The modular design of the main body base 1 and the replaceable tooth tip 2 simplifies the maintenance and replacement process, reduces the maintenance cost and time, and the design of the replaceable tooth tip 2 enables the worn part to be replaced separately without replacing the entire plowshare, which reduces the use cost and prolongs the life of the equipment; then the angle between the replaceable tooth tip 2 and the land is changed through the angle adjustment mechanism 3. By adjusting the angle between the tooth tip and the ground, the tillage effect can be further optimized, energy consumption can be reduced, and the operation efficiency can be improved. For example, when deep plowing, the cutting angle of the tooth tip can be appropriately increased; when surface plowing, the cutting angle can be reduced to avoid damaging the soil surface.

[0025] Optionally, in some embodiments, please refer to Figure 1 The main body base 1 includes a fixed base 11 and a movable base 12. The movable base 12 is rotatably connected to the fixed base 11. A square hole is opened on the movable base 12. An anti-wear plate 5 is welded on one end of the fixed base 11 away from the movable base 12. The square hole is opened on the end of the movable base 12 away from the fixed base 11.

[0026] In this arrangement, the fixed base 11 is used to connect with the agricultural machinery, and the anti-wear plate 5 can effectively reduce the wear of the base body during agricultural operations, especially in hard or abrasive soils, thereby extending the service life of the equipment. The square hole is opened at the end of the movable base 12 away from the fixed base 11, so that the fixing bar 4 can more firmly fix the tooth tip, ensuring that the tooth tip is not easy to loosen or fall off during high-intensity operations, thereby enhancing the stability of the overall structure. The movable base 12 can be disassembled and repaired separately without replacing the entire main base 1, thereby reducing maintenance costs and time.

[0027] Optionally, in some embodiments, please refer to Figure 1-Figure 3 The angle adjustment mechanism 3 includes a rotating shaft 31, a fixing bolt 32, a nut 33, and an adjustment plate 34. The rotating shaft 31 is rotatably connected to the fixed base 11, the movable base 12 is fixedly connected to the rotating shaft 31, the adjustment plate 34 is welded to the fixed base 11, and a plurality of adjustment through holes 35 are provided on the adjustment plate 34. A lubrication through hole is provided at one end of the movable base 12 close to the adjustment plate 34, the fixing bolt 32 passes through the adjustment through hole 35 and the lubrication through hole, and the nut 33 is threadedly connected to the fixing bolt 32.

[0028] With such arrangement, when it is necessary to adjust the angle between the replaceable tooth tip 2 and the ground, the movable base 12 is rotated around the rotating shaft 31 to connect the lubrication through hole on the movable base 12 with the adjustment through hole 35 on the adjustment plate 34, and is fastened by fixing bolts 32 and nuts 33 to ensure that the movable base 12 remains stable after adjustment, prevent the angle from changing during operation, and improve operation stability; the lubrication hole is convenient for adding lubricating oil, reduces the friction when the fixing bolt 32 passes through the adjustment plate 34, and extends the life of the equipment; through multiple adjustment through holes 35, users can choose different angles according to specific needs to adapt to various soil conditions such as soft and hard soil conditions, and improve operation efficiency and quality.

[0029] Optionally, in some embodiments, please refer to Figure 1 The movable base 12 is fixedly connected with a cutting blade 6 away from the replaceable tooth tip 2, and the cutting blade 6 is in an inverted triangle shape.

[0030] With such arrangement, the sharp edge of the cutting blade 6 can effectively break up soil clods and cut off weed roots, thus improving soil structure and creating better conditions for subsequent tillage. The cutting blade 6 is located at the front end of the movable base 12 and can cut before the replaceable tooth tip 2 contacts the soil, thereby reducing the wear of the tooth tip and extending its service life. At the same time, the inverted triangle shape has a streamlined feature, which can reduce the resistance of soil and weeds during operation, reduce the energy consumption of the equipment and improve operating efficiency.

[0031] Optionally, in some embodiments, please refer to Figure 1-Figure 3 The replaceable tooth tip 2 is made of 65Mn spring steel, and the surface of the replaceable tooth tip 2 is sprayed with tungsten carbide coating to improve wear resistance.

The strength and toughness of 65Mn spring steel combined with the wear resistance of tungsten carbide coating significantly extends the service life of the replaceable tooth tip 2, allowing it to maintain efficient operating performance in hard soil, gravel, etc.

[0033] Optionally, in some embodiments, please refer to Figure 1 The main body base 1 is provided with a safety through hole 7, and a safety pin 8 is fixedly connected in the safety through hole 7.

[0034] With such arrangement, when the tillage resistance exceeds the set value, the safety pin 8 breaks, the agricultural machinery receives the break signal, stops tilling, protects the plow teeth and agricultural machinery equipment, and improves the safety of the equipment. The design of the safety pin 8 is simple and low-cost. After it breaks, only the safety pin 8 needs to be replaced without repair or replacement of more expensive parts, which reduces the maintenance cost. The set value of the safety pin 8 can be adjusted according to different soil conditions and operating requirements to ensure that effective overload protection can be provided under various complex working conditions.

[0035] Optionally, in some embodiments, please refer to Figure 1 A sensor installation through hole is provided on the side of the replaceable tooth tip 2, and a soil moisture sensor 9 is installed in the sensor installation through hole.

[0036] With such an arrangement, the soil moisture sensor 9 can monitor key parameters such as soil moisture and tillage depth in real time, helping farmers to accurately grasp soil conditions and realize precision agricultural operations. Through real-time data, farmers can adjust tillage depth, sowing density and irrigation amount according to soil moisture and other parameters, optimize tillage decisions, and improve crop yield and quality. In addition, the soil moisture sensor 9 is located on the side of the replaceable tooth tip 2, which is easy to clean and less likely to be blocked by soil.

[0037] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
