Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a rotary tiller blade holder. Background Technology

[0002] Rotary tillers, as important agricultural machinery, are widely used for soil tillage, soil breaking, and compound fertilizer processing. Their core function is to cut, break, and mix the soil through rotating blades, thereby improving soil looseness and aeration. The blade holder, as a crucial component of the rotary tiller, is mainly used to fix and arrange the blades; its structural design directly affects operating efficiency, energy consumption, and tillage quality. Traditional blade holders suffer from problems such as easy wear and complex installation. Some blade holders have complex structures and high manufacturing costs, making it difficult to meet the requirements of agricultural tillage, such as easy maintenance, low energy consumption, easy installation, low cost, and stability. Therefore, developing a new rotary tiller blade holder has become an urgent problem for those skilled in the art. Utility Model Content

[0006] A tool holder, which passes through the support member and is connected to the connecting assembly, is equipped with a plurality of blade assemblies. The tool holder is configured as a spline shaft. Each blade assembly includes two opposing blades and a connecting seat. The connecting seat has a through hole in the middle, and the through hole is adapted to the spline of the tool holder, so that the connecting seat is snapped onto the tool holder. The two opposing blades are connected to the outer side of the connecting seat.

[0007] Optionally, the support member is provided with two symmetrical arm plates, a web plate is installed at one end of the two arm plates, the web plate connects the two arm plates, and a baffle is provided at the top of the web plate.

[0008] Optionally, the connecting assembly includes a first hinge seat, a second hinge seat, and a hinge, wherein the first hinge seat is mounted on one end of the tool holder and is detachably connected to the tool holder;

[0009] The second hinge seat is disposed at the end of the arm plate away from the tool holder. The installation position of the second hinge seat is adapted to the length of the hinge, so that the hinge is hinged to the second hinge seat and the first hinge seat.

[0010] Optionally, the tool holder passes through the arm plate and is connected to the two first hinge seats at both ends.

[0011] Optionally, the spline of the tool holder is set to an eight-tooth spline, and the opening of the spline is in the shape of an inverted trapezoid.

[0012] Optionally, a motor is mounted on the second hinge seat, the motor being used to drive the tool holder to rotate.

[0014] Optionally, a mudguard is also provided at one end of the arm plate near the first hinge seat, the mudguard being used to prevent excessive mud from seeping into the connecting assembly.

[0015] The beneficial effects of this application are as follows:

[0016] 1. The spline shaft and connecting seat snap-fit ​​setting on the blade holder provided in this application realizes stepless sliding adjustment of the blade assembly along the axial direction through the meshing characteristics of the spline teeth, while ensuring the accurate positioning of the distance between the blades, avoiding the positioning deviation problem caused by traditional bolt fixing, and improving the uniformity of tillage.

[0017] 2. The symmetrically arranged connecting components and the rigid fit between the spline shaft provided in this application effectively reduce the axial movement and radial wobble of the blade holder during high-speed rotation, reduce the impact of vibration on the overall structure of the rotary tiller, and extend the service life of the equipment.

[0018] 3. The blade assembly provided in this application adopts a symmetrical design, that is, the two blades are distributed relative to the connecting seat to ensure balanced rotational force, avoid eccentric vibration caused by uneven mass, and reduce the risk of blade loosening and falling off.
