Description

Technical Field

[0001] This utility model relates to the field of micro-tiller technology, specifically to an anti-tangling blade assembly for micro-tillers. Background Technology

[0002] Mini tillers are powered by small diesel or gasoline engines and are characterized by their light weight, small size, and simple structure. They are widely applicable to dry land, paddy fields, and orchards in plains, mountains, and hills. Equipped with appropriate implements, they can perform tasks such as pumping water, generating electricity, spraying pesticides, and watering. They can also tow trailers for short-distance transport. Mini tillers can move freely in fields, making them convenient for users to operate and store. They eliminate the problem of large agricultural machinery being unable to access mountainous fields, making them the best alternative to oxen for farmers.

[0003] Existing rotary tiller mechanisms lack anti-tangling functionality, resulting in a large amount of weeds, straw, stubble, and other debris getting tangled on the blade rollers during prolonged weeding operations. This tangling eventually reaches the same radius as the rotary tiller's rotation, reducing the effective tillage depth and failing to meet the tillage depth requirements for rotary tillage. To address this, we propose an anti-tangling blade assembly for rotary tillers. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-tangling blade assembly for a micro-tiller in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] An anti-tangle blade assembly for a micro-tiller includes: a blade shaft, multiple mounting plates evenly arranged vertically on the outer side of the blade shaft, and multiple sets of blades detachably mounted on the top of each mounting plate via mounting posts; multiple blades arranged on the outer side of the mounting plates; and multiple fixing brackets evenly and detachably mounted vertically on the inner side of each blade, with two symmetrically arranged fixing shafts installed inside each fixing bracket.

[0007] Furthermore, the cutter shaft has a regular hexagonal structure, and the interior of the cutter shaft also has a through slot with a regular hexagonal structure.

[0008] Furthermore, each set of blades is provided with multiple blades, and the surface of each blade is provided with serrations.

[0009] Furthermore, the mounting plate has an internal mounting groove that matches the outer wall of the cutter shaft, and the cutter shaft is connected to the mounting groove by spot welding.

[0010] Furthermore, fasteners are fitted onto the circumferential surfaces at both ends of each mounting post, and external threads are provided on the circumferential surfaces at both ends of each mounting post. Internal threads are provided inside the fasteners, and the mounting posts and the fasteners are connected by threads.

[0011] Furthermore, each of the fixed shafts has a nut threadedly connected to its inner circumferential surface, and a fixing hole is provided on the side of the mounting plate that contacts the fixed shaft, with the fixed shaft and the fixing hole being interference fit.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention allows for the removal of the mounting plate and its internal blade assembly by disassembling the mounting column, facilitating replacement. Furthermore, the removal of the fixing frame and fixing shaft enables the disassembly of the cutting tool. These steps facilitate the inspection and maintenance of the blade assembly and cutting tool, ensuring long-term performance. Additionally, the combination of the blade assembly and cutting tool prevents entanglement with weeds, straw, and stubble, thus improving the actual performance and quality of use.
