Description

Technical Field

[0001] The utility model relates to the technical field of rotary tillage knives, in particular to a single-hole rotary tillage knife which is convenient to install and use. Background Technique

[0002] Rotary tillage operations can improve the soil structure, thus providing good conditions for subsequent mechanical operations, seed germination, and crop growth. Rotary tillage knives are the core components of rotary tillers and play a crucial role in the process of tillage and land preparation operations. At present, the rotary tillage knives on the market still have various deficiencies and cannot meet the needs of production and life.

[0003] For example, the rotary tillage knife disclosed in the authorized announcement number CN205946526U, although it realizes the extension of the service life of the rotary tillage knife and reduces the replacement and use costs of the rotary tillage knife under the condition of the same operation amount, it does not solve the problem that there is usually only bolt installation and fixation between the existing rotary tillage knife and the tool holder, and there is easy shaking between the rotary tillage knife and the tool holder.

[0004] Therefore, a single-hole rotary tillage knife which is convenient to install and use is proposed for the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a single-hole rotary tillage knife which is convenient to install and use, including a rotary tillage knife body. A tool holder is arranged on one side of the rotary tillage knife body. The tool holder is connected with a tool holder through a fastening bolt. Grooves are respectively arranged on both sides of the upper and lower ends inside the tool holder. A buffer clamping structure is arranged inside the grooves. The buffer clamping structure includes a sliding rod. A limiting block is fixedly arranged at the central position of the sliding rod. Sliding sleeve blocks are respectively sleeved on the sliding rods on both sides of the limiting block. Buffer springs are arranged on the sides of the sliding sleeve blocks away from the limiting block. A connecting frame one is arranged on the sliding sleeve blocks. One end of the rotating rod is rotatably connected with the connecting frame one. The other end of the rotating rod is rotatably connected with the inside of the connecting frame two. The connecting frame two is arranged on a buffer plate. A plurality of anti-slip protrusions are arranged on the side of the buffer plate away from the connecting frame two.

[0006] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0007] The utility model realizes the connection between the tool holder and the tool holder by passing the fastening bolt through the bolt hole of the tool holder and the through hole on the tool holder. Removing the fastening bolt can remove the rotary tillage knife body, which is convenient for installation and disassembly.

[0008] The utility model is provided with a sliding rod, a sliding sleeve block, a buffer spring, a rotating rod and a buffer plate. After the tool handle is inserted into the tool magazine, the buffer plate is stressed to drive the rotating rod to rotate. The rotation of the rotating rod drives the sliding sleeve block to move on the sliding rod, and the movement of the sliding sleeve block compresses the buffer spring, so as to facilitate buffering the installation of the tool handle. At the same time, the buffer plate can clamp and fix the tool handle to prevent the rotary tillage knife body from shaking in the tool magazine after installation.

[0009] The utility model is provided with a plurality of anti-slip protrusions on the surface of the buffer plate. The anti-slip protrusions contact with the surface of the tool handle, increasing the friction area and preventing the rotary tillage knife body from shaking in the tool magazine during use.

Detailed Description of the Embodiment

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0016] As shown in the atta Figures 1-3As shown in the figure, a single-hole rotary tillage knife that is convenient for installation and use provided by the utility model includes a rotary tillage knife body 1. A knife handle 2 is arranged on one side of the rotary tillage knife body 1. The knife handle 2 is connected to a tool holder 3 through a fastening bolt 4. Its characteristics are as follows: Grooves 302 are respectively opened on both sides of the upper and lower ends inside the tool holder 3. A buffer clamping structure 5 is arranged inside the grooves 302. The buffer clamping structure 5 includes a sliding rod 51. A limiting block 52 is fixedly arranged at the central position of the sliding rod 5. Sliding sleeve blocks 53 are respectively sleeved on the sliding rods 51 on both sides of the limiting block 52. A buffer spring 54 is arranged on the side of the sliding sleeve block 53 away from the limiting block 52. A connecting frame one 55 is arranged on the sliding sleeve block 53. One end of the connecting frame one 55 is rotatably connected to one end of a rotating rod 56. The other end of the rotating rod 56 is rotatably connected to the inside of a connecting frame two 57. The connecting frame two 57 is arranged on a buffer plate 58. A plurality of anti-slip protrusions 59 are arranged on the side of the buffer plate 58 away from the connecting frame two 57.

[0017] Specifically, bolt holes 301 are respectively opened on both sides inside the tool holder 3. The fastening bolt 4 sequentially passes through the bolt holes 301 opened on the tool holder 3 and the hole positions opened on the knife handle 2 to connect the tool holder 3 with the rotary tillage knife body 1.

[0018] Specifically, the sliding rod 51 is longitudinally arranged in the groove 302.

[0019] Specifically, one end of the buffer spring 54 is connected to the sliding sleeve block 53, and the other end of the buffer spring 54 is connected to the inner wall of the groove 302.

[0020] Working principle: When in use, insert the rotary tillage knife body 1 into the tool holder 3, and sequentially pass the fastening bolt 4 through the bolt hole 301 and the through hole on the knife handle 2 to connect the rotary tillage knife body 1 with the tool holder 3. After the knife handle 2 is inserted into the tool holder 3, the buffer plate 58 is stressed to drive the rotation of the rotating rod 56. The rotation of the rotating rod 56 drives the sliding sleeve block 53 to move on the sliding rod 51. The movement of the sliding sleeve block 53 compresses the buffer spring 54, thereby facilitating a buffering effect on the installation of the knife handle 2. At the same time, the buffer plate 58 can play a clamping role on the knife handle 2 to prevent the rotary tillage knife body 1 from shaking in the tool holder after installation. With a plurality of anti-slip protrusions 59 arranged on the surface of the buffer plate 58, the anti-slip protrusions 59 are in contact with the surface of the knife handle 2, increasing the friction area, preventing the rotary tillage knife body from shaking in the tool holder during use, and making the fixation of the rotary tillage knife body 1 and the tool holder 3 more stable.
