Preferably, the first cutter structure comprises a first cutter disc sleeved outside the connecting shaft, thick plates sleeved outside the connecting shaft are arranged on the upper side and the lower side of the first cutter disc, and four blades which are annularly arranged along the axis of the cutter disc are connected with the outer side of the first cutter disc through screws.

Preferably, the second cutter structure comprises a second cutter disc sleeved outside the connecting shaft, thick plates sleeved outside the connecting shaft are arranged on the upper side and the lower side of the second cutter disc, a conical ring is connected to the outer side of the second cutter disc, and four blades which are annularly arranged along the axis of the conical ring are connected with the outer side of the conical ring through screws.

Preferably, the diameter of the first cutterhead is larger than that of the second cutterhead.

Preferably, the first cutter structure is provided with a nut in threaded connection with the connecting shaft.

The utility model has the beneficial effects that: the cutter is simple in structure and high in practicability, and by means of the first cutter structure and the second cutter structure, long shrubs can be efficiently cut when farmlands are barren, the shrubs can be cut into multiple sections, the treatment difficulty of the shrubs in the later period is reduced, and the efficiency is improved.

Drawings

Fig. 1 is a schematic structural view of the present utility model.

Fig. 2 is a schematic connection diagram of a first cutterhead according to the present utility model.

Fig. 3 is a schematic connection diagram of a second cutterhead according to the present utility model.

The cutter comprises a first cutter head, a second cutter head, a 3-conical ring, a 4-blade, a 5-thick plate, a 6-nut, a 7-positioning sleeve, an 8-connecting shaft, a 9-first cutter structure, a 10-second cutter structure and a 11-limiting plate.

Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 1 to 3, a cutter structure comprises a connecting shaft 8, the bottom of the connecting shaft 8 is provided with a limiting plate 11, the connecting shaft 8 is sequentially sleeved with a first cutter structure 9 and a second cutter structure 10 from top to bottom, the first cutter structure 9 and the second cutter structure 10 are detachably connected with a plurality of blades 4 which are annularly arranged along the axes of the blades, a positioning sleeve 7 is arranged between the first cutter structure 9 and the second cutter structure 10, the positioning sleeve 7 is sleeved outside the connecting shaft 8, the upper end and the lower end of the positioning sleeve are respectively connected with the first cutter structure 9 and the second cutter structure 10, and the lower end of the blade 4 of the second cutter structure 10 is lower than the bottom end position of the limiting plate 11. So that the position at which the blade 4 of the second cutter structure 10 cuts can be lower.

In this embodiment, the first cutter structure 9 includes a first cutter disc 1 sleeved outside the connecting shaft 8, thick plates 5 sleeved outside the connecting shaft 8 are respectively disposed on the upper and lower sides of the first cutter disc 1, and four blades 4 annularly arranged along the axis of the first cutter disc 1 are connected with the outer side screws of the first cutter disc 1. The provision of the stiffening plate 5 improves stability.

In this embodiment, the second cutter structure 10 includes a second cutter disc 2 sleeved outside the connecting shaft 8, thick plates 5 sleeved outside the connecting shaft 8 are respectively disposed on the upper and lower sides of the second cutter disc 2, a conical ring 3 is connected to the outer side of the second cutter disc 2, and four blades 4 annularly arranged along the axis of the conical ring 3 are connected with screws. The provision of the conical ring 3 reduces the longitudinal height of the blades 4 of the second cutter structure 10 so that they are positioned below the limiting plate 11 and the cutting position can be lower.

In this embodiment, the diameter of the first cutterhead 1 is larger than the diameter of the second cutterhead 2.
