Embodiment Construction

[0021] see figure 1 , a cutter for a rotary tiller, comprising a cutter body 1, a handle 2 and a cutter seat 4, the cutter body 1 includes a cutter head 101 and a blade body 102, the arc from the blade body 102 to the cutter head 101 is excessive, and the handle 2 is accompanied by a reinforced area 3. Combined with the reinforced area 3, the width of the handle 2 is 36-80mm.

[0022] see figure 1 , figure 2 , image 3 as well as Figure 4 , The reinforced area 3 and the handle 2 can be a single piece or a combined piece.

[0023] When the reinforcement zone 3 is one piece, the reinforcement zone 3 is arranged on one side of the back edge of the handle 2 . Can only reach shank 2, see figure 2 ; It can also extend continuously to the cutter head 101, see figure 1 , it is best to reinforce the region and the handle 2 as one piece and only extend to the handle 2.

[0024] When the reinforced area 3 is an assembly, the reinforced area 3 is arranged on the knife seat 4, a...

Abstract

The invention relates to a rotary cultivator cutter which comprises a cutter body, a cutter handle and a cutter holder, wherein the cutter body comprises a cutter head and a cutter blade, the cutter blade is in arc transition to the cutter head, the cutter handle is provided with a reinforcing area, and the width of the cutter handle is widened by combining the reinforcing area. The cutter handle has the advantages of high strength, uneasy breakage, long service life, low cost and high efficiency, solves the technical problem that the cutter is easy to be broken while in high-power operation and is suitable for high-power rotary cultivators with horsepower more than 80.

Description

technical field [0001] The invention relates to a cutter, in particular to a cutter for a rotary tiller. Background technique [0002] Rotary tiller knives are basically divided into two types: sickle-type knives and cutterhead-type knives. The sickle-type knives used by the rotary tiller are now using the national standard GB / T5669-1995, which stipulates that the width of the tool handle for the rotary tiller is 25 -0.5 0 mm and 30 -0.5 0 mm, but this kind of tool is installed on a rotary tiller with more than 80 horsepower. Because of the characteristics of the rotary tiller itself, at a point in time when it touches the ground, it often works with a single knife, especially when the cultivated ground is hard. The load of a single knife is very heavy, especially the handle of the knife is very easy to break, resulting in damage to the knife. In fact, the current rotary tiller knives cannot be used normally on high-horsepower rotary tillers; although the cutterhead kni...
