[0010] The above-mentioned two fixed cutters are installed between the rotary tillers, and the arc-shaped cutting edge of the fixed cutter is close to the fixed end of the rotary tiller.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1、The fixed cutter does not move during use, and when weeds are entangled on the rotating rotary tiller, the fixed cutter can cut the weeds, thereby avoiding the occurrence of the situation that weeds are entangled on the rotary tiller, and maintaining the continuous operation of the machine.

[0013] 2. The machine body is provided with a cross bar, a plurality of fixing plates are fixedly arranged on the cross bar, screw holes are arranged on the connecting end of the fixing plate and the fixed cutter, and the fixing plate and the fixed cutter are connected through bolts and nuts. Through the movable connection of the fixed cutter and the fixing plate, the fixed cutter is convenient to disassemble and assemble, and the fixed cutter is convenient to replace when the fixed cutter is damaged.

[0014] 3. Because the cutting edges of the existing rotary cutters are staggered on the left and right sides of the rotary cutter mounting sleeve, the cutting edges of the fixed cutter extend close to the inner side of the rotary cutter, and the cutting edges of the fixed cutter and the cutting edges of the rotary cutter are staggered with each other, so that the effective area for cutting weeds can be maximized.

[0015] Other advantages, objects and features of the present application will be apparent to those skilled in the art in view of the following detailed description and drawings. The objects and other advantages of the present application can be realized and attained by the structure particularly pointed out in the specification. BRIEF DESCRIPTION OF DRAWINGS

[0018] Fig. 2 The present application is another angle of the three-dimensional connection structure schematic diagram.

[0019] Fig. 3 The present application is a front view structure schematic diagram.

[0020] Among them, the machine body 1; the rotating shaft 2; the rotary cutter 3; the fixed cutter 4; the cross bar 5; the fixing plate 6; the rotary cutter mounting sleeve 7. DETAILED DESCRIPTION

[0021] The preferred embodiments of the present application will be described in detail below with reference to the drawings. It should be understood that the preferred embodiments are only for the purpose of illustrating the present application, and are not intended to limit the protection scope of the present application.

[0022] As Figs. 1-3The utility model discloses a kind of puller of anti-winding grass, it includes body 1, is equipped with rotating shaft 2 on body 1, rotating shaft 2 is equipped with rotary tiller 3, a plurality of fixed cutters 4 are installed on body 1, the blade tip of fixed cutter 4 is across between rotary tiller 3 to the weed between rotary tiller 3 is cut, such structure, in use process, fixed cutter 4 does not move, when weed is wound on rotating rotary tiller 3, fixed cutter 4 can cut weed, to avoid the occurrence of weed winding rotary tiller 3, can keep the sustained operation of machine.

[0023] Further, horizontal rod 5 is installed on body 1, a plurality of fixed plates 6 are fixedly arranged on horizontal rod 5, screw holes are equipped in the connecting end of fixed plate 6 and fixed cutter 4, and fixed plate 6 is connected with fixed cutter 4 by bolt and nut, and such structure, fixed cutter 4 and fixed plate 6 are movably connected, convenient to disassemble and assemble, when fixed cutter 4 is damaged, it is favorable to replace.

[0024] Further, rotary tiller mounting sleeve 7 is arranged on rotating shaft 2, and rotary tiller 3 is arranged on rotary tiller mounting sleeve 7, and the blade tip of rotary tiller 3 is staggered and arranged on the left and right sides of rotary tiller mounting sleeve 7, and two fixed cutters 4 are arranged between rotary tiller 3, and the arc blade tip of fixed cutter 4 is close to the fixed end of rotary tiller 3, because the blade tip of existing rotary tiller 3 is staggered and arranged on the left and right sides of rotary tiller mounting sleeve 7, so, the blade tip of fixed cutter 4 is extended close to the inner side of rotary tiller 3, and the blade tip of fixed cutter 4 and the blade tip of rotary tiller 3 are staggered, to maximize guarantee the effective area of cutting weed.

[0025] The above is only the preferred embodiment of the utility model, and is not any form of the utility model, and any simple modification, equivalent change and modification of the above embodiment, which does not deviate from the technical scheme content of the utility model and is based on the technical essence of the utility model, still belongs to the range of the technical scheme of the utility model.
