Description

Technical Field

[0001] The present invention relates to a component constituting a tillage blade used in a tillage working device that tills cultivated land and the like, and crushes subsoil and subsoil to improve the air permeability and drainage of the cultivated land.

Background Art

[0002] The blade for tillage work used in the tillage working device tills the field by towing the tillage working device with a traveling vehicle such as a tractor while inserted into the soil, and crushes the subsoil and subsoil (impervious layer) to improve the air permeability and drainage of this field.

[0003] Regarding the excavation resistance when lifting the excavated soil in the excavated subsoil part and digging up the soil to the side in the working progress direction, in view of improving the excavation resistance acting on the chisel and the excavation plate, the excavation resistance applied to each component and the traveling vehicle can be effectively reduced. As a result, the durability of each component in the tillage working claw can be improved, a traveling vehicle with low output can be used, and further, since the durability of each component of the tillage working claw is improved, the maintenance cost such as repair and replacement of each component of this tillage working claw can be reduced. By using a traveling vehicle with low output, the fuel cost can be reduced, and even by using a traveling vehicle with low output, an efficient excavation work can be performed. For these purposes, each configuration of the tillage working claw can be divided, and a tillage working claw provided with a cut portion in the width direction of the chisel is described.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, many of these tilling tines, as well as conventional tilling tines, have their tips angled in the direction of digging, creating a blade-like shape, in order to ensure sufficient digging force into the soil. While this shape may ensure a certain degree of force to bite into the soil, the tip naturally becomes dull over time and loses its ability to penetrate the soil. This is not limited to the tip of the tilling blade; when voids are created in the tilled soil and the soil tries to return to its original position, the tilling blade is pulled by the tiller, causing this soil to collide with parts around the arm. As a result, tilled soil collides with the sides of the tilling blade and the bracket that connects the tilling blade to the arm, and wear on the sides has also become a problem. Therefore, there is still room for improvement in terms of the amount of wear (reduction with use) on parts other than the tip of the tilling blade.

[0006] In large-scale agriculture, the farming machinery naturally becomes larger, and so do the tines used for farming. This places a greater burden on the chisel and its surrounding components. The increase in the size of farming machinery naturally leads to larger components for the tines, creating a demand for long-lasting chisels and other farming parts.

[0007] One example of the problems addressed by this invention is the effective reduction of digging resistance applied to each component of the tilling tines and surrounding parts, as well as to the vehicle, while improving the durability of each component of the tilling tines and surrounding parts, thereby reducing costs and enabling efficient tillage. [Means for solving the problem]

[0008] To achieve this objective, the cultivating blade according to the present invention comprises at least the following components.

[0009] That is, the first embodiment of the present invention is In a bracket for attaching a chisel to an arm of a tilling machine that is installed on the main body of the tilling machine, This is a bracket for a cultivating blade, wherein at least one side of the bracket, at least a portion of which is perpendicular to the digging direction of the chisel, is made thicker.

[0010] Other embodiments of the present invention include: The bracket for a cultivating blade described above is characterized in that at least a portion of both sides of the bracket's side surface, which is perpendicular to the digging direction of the chisel, is given thickness.

[0011] Other embodiments of the present invention include: The bracket for cultivating blades described above is characterized in that the thickened portion of the bracket is positioned near the joint between the arm and the bracket.

[0012] Other embodiments of the present invention include: The bracket for a cultivating blade described above has a curved shape in which the thickened portion of the side of the bracket, which is perpendicular to the digging direction of the chisel, is designed to distribute the stress generated when the chisel digs.

[0013] Other embodiments of the present invention include: The bracket for a cultivating blade described above has a thickened portion on its side perpendicular to the digging direction of the chisel, which extends continuously along the entire length of the bracket.

[0014] Other embodiments of the present invention include: The bracket for cultivating blades described above has a portion of its side surface that is thickened perpendicular to the digging direction of the chisel, and this portion has multiple steps of thickness variation.

[0015] Other embodiments of the present invention include: The bracket for cultivating blades described above is characterized in that the thickened portion of the bracket is equipped with an angle adjustment mechanism that can be adapted to the mounting direction of the chisel.

[0016] Another embodiment of the present invention is a tilling blade fixed to an arm with the bracket described above. [Effects of the Invention]

[0017] By adopting such a configuration, by providing thickness to the side surface of the bracket, when the chisel attached to the tiller body excavates the soil, durability can be provided to the side surface where wear due to the impact of soil on the bracket is severe in the rearward excavation direction, and wear of the bracket can be reduced. As a result, the efficiency of tillage work is improved and the replacement frequency of the bracket is reduced.

[0018] Also, by adopting such a configuration, the stress generated during soil excavation is more dispersed, and the impact on the joint part to the arm or the like can be reduced. Therefore, the overall durability is further improved. With this design, the lifespan of the bracket is extended and the maintenance cost of the tiller is reduced.

[0019] Also, by adopting the configuration described above, the thickened part is arranged near the joint of the arm and the bracket, so that the strength of the joint is increased and the structural strength of the entire assembled tillage blade is improved. As a result, the risk of the bracket coming off is reduced and safety is enhanced.

[0020] By adopting such a configuration, the thickened part can also be made into a shape according to the usage purpose. For example, by giving it a curved shape, the stress generated during excavation is effectively dispersed. As a result, local wear and damage of the bracket are prevented and stable performance is maintained over a long period.

[0021] By adopting such a configuration, the thickened part extends continuously over the entire length of the bracket, so that the overall durability is evenly strengthened. With this design, the overall strength of the bracket is increased and partial wear and damage are prevented.

[0022] By adopting such a configuration, having a plurality of stepped thickness changes allows the stress applied to the side surface of the bracket to be absorbed step by step, improving the overall durability. As a result, the wear of the bracket is made uniform, and the service life is extended.

[0023] By adopting such a configuration, the thickened part having an adaptable angle adjustment mechanism enables flexible response to the attachment direction of the chisel. With this design, it can cope with various tillage conditions, improving the working efficiency.

[0024] By adopting such a configuration, the bracket is fixed to the arm, so that the tillage blade is stably attached, improving the durability against vibrations and impacts during tillage operations. As a result, the working safety is enhanced, and efficient tillage becomes possible. By having such features, the present invention can improve the wear resistance of the parts in the bracket used for the tillage blade and can be used for a longer period together with the tillage blade.

[Figure 2] It is a schematic view of the bracket according to the present invention seen from above. [Figure 3] It is a view showing an overview of the bracket according to the present invention. [Figure 4] It is a schematic view of a tillage blade provided with the bracket according to the present invention.

Modes for Carrying Out the Invention

[0026] Hereinafter, embodiments of the tillage blade of the present invention will be described based on the drawings. The configuration of the bracket used for the tillage blade exemplified below does not limit the present invention. Also, hereinafter, the excavation direction will be described as the front, the reverse excavation direction as the rear, and the direction intersecting the excavation direction as the width direction.

[0027] Figure 1 is a side view of the bracket of this embodiment. A thickness portion 22 is formed on the side of the bracket 2. The bracket 2 has a forward-sloping portion for connecting the chisel 1 and includes a frame A and a connecting portion 23 for connecting to a vehicle (not shown). The bracket 2 may also include a wing 3 positioned behind the bracket 2 and attached to the arm A.

[0028] In the present invention, the bracket 2 is preferably a cast product, but the manufacturing method is not particularly important as long as it can produce a shape within the range described in this disclosure. When the bracket 2 is cast, its shape may be limited in relation to the mold.

[0029] Furthermore, regarding the thickness portion 22, although its partial shape is not important, during tillage work, the tilling blade moves in the tilling direction, causing the tilled soil to return to the area near the connection point with the arm, often resulting in the soil colliding with the parts near the tilling blade, including the bracket. The inventor of the present invention was the first to focus on this point and discovered that by reinforcing a part of the side of the bracket, particularly near the arm connection point, wear on the bracket can be reduced and the product life can be extended, leading to the present invention. Therefore, the thickness portion of the bracket of the present invention may be created by adjusting its position depending on the shape of the chisel used and the soil being tilled. In this disclosure, tilled soil refers to all soil that is moved when the chisel penetrates it.

[0030] The chisel 1 that can be used in the bracket of the present invention is substantially rectangular in shape and has a tilling blade at its tip in the width direction, and its shape is not particularly limited as long as it can be coupled to the bracket of the present invention.

[0031] The bracket 2 of the present invention is connected to the arm A provided on the main body of the farming machine by a coupling and fixing mechanism for attachment. In this embodiment, this coupling and fixing mechanism 23 has a hole that can be connected to the arm A with a nut and bolt, but other means are also included in the present invention. The bracket 2 is also provided with a notch 24 into which the arm A fits (Figure 2). By appropriately changing this notch, the chisel of the present invention can be connected to various arms via the bracket.

[0032] Furthermore, the bracket 2 is equipped with a coupling and fixing mechanism (not shown) that connects to the chisel 1. This coupling and fixing mechanism (not shown) can be any mechanism that can achieve sufficient strength to withstand the stress that the chisel 1 and bracket 2 experience during cultivation, and is usually a nut and bolt, but other coupling means are also included in the present invention.

[0033] Next, in this embodiment, as shown in Figure 4, a drilling plate (wing 3) may be provided that is coupled to the arm A at the rear of the chisel 1. The wing 3 can be coupled to the arm A by a coupling mechanism. In this embodiment, the wing 3 is formed in a substantially trapezoidal shape from the top to the bottom, is divided into substantially three sections in the width direction, and has surfaces 31 on both the left and right sides that protrude forward.

[0034] Figure 3 is a perspective view including the thickness portion 22 of the bracket according to the present invention. The thickness and shape of the thickness portion 22 can be appropriately changed depending on the application and manufacturing method. During tillage, soil collides with the bracket 2 behind the direction of travel of the tilling blade. More specifically, when the chisel enters the soil, the soil is moved aside in the width direction, and the soil moves in a way that bounces it up in the vertical direction depending on the angle at which the chisel enters the soil. Due to these two axial elements and the tillage speed, the impact force of the soil on the side of the bracket 2 changes.

[0035] The collision of soil with the bracket 2, as described above, varies depending on the application and tilling conditions, but generally, as shown in Figure 3, when the bracket is equipped with a connecting and fixing mechanism 23 at the front and rear with a thickness portion 23 in between, tilled soil tends not to directly hit the front connecting and fixing mechanism 23 for the reasons mentioned above, but rather to hit the thickness portion 22 or the rear connecting and fixing mechanism 23. Therefore, it is reasonable to provide a thickness portion 22 behind the front connecting and fixing mechanism 23 to protect the bracket body and the rear connecting and fixing mechanism 23.

[0036] In this invention, the elements of the cultivator blade are preferably made of iron plates, but the material can be appropriately selected depending on the configuration. Furthermore, the size of each component for its intended use can be appropriately selected depending on the configuration, size, and application of the cultivator body to which it is attached. In addition, various coatings to provide weather resistance and rust resistance to each component can be appropriately selected by those skilled in the art.

[0037] Furthermore, the present invention is not limited to the embodiments described herein, and can be implemented in configurations that do not depart from the content described in each claim. [Explanation of Symbols]
