Abstract
The utility model discloses a kind of rotovator rotary blade, comprise blade and connect the cutter pipe of blade, cutter pipe is connected with rotovator drive shaft, and described cutter pipe periphery is connected with upper and lower two set of blades, each set of blades is equipped with four the 90 degree blades intersected; Described cutter pipe is provided with two connecting holes through center, two connecting holes connect main shaft by quick clamping device, quick clamping device comprises the bearing pin being each passed through two connecting holes, main shaft, bearing pin one end connects an end of semicircle snap ring by torsion spring, and the other end is connected the other end of semicircle snap ring.The utility model connects cutter pipe and main shaft by pin shaft structure, and the coupling mechanism force of the semicircle snap ring generation adopting torsion spring to connect, holds cutter pipe and main shaft tightly and reaches quick-clamping object between rotary blade and main shaft.
Description
Technical field
The utility model relates to a kind of cutter, specifically a kind of rotovator rotary blade.
Background technology
Current rotovator is the common equipment for ploughing, digging, and depth of turning soil is large, degree of refinement is high to require rotary blade to have soil, and connects the technical requirements such as main shaft clamping speed is fast.The connected mode of its rotary blade of existing rotovator and main shaft mostly have employed bolt fastening structure, and this kind of connected mode not only loads and unloads trouble, and often occurs that bolt looseness etc. affects rotary blade and to loosen the soil the technical problem of performance along with using.How to realize quick, the stable installation capability of rotary blade and raising is loosened the soil, the technical scheme of refining efficiency is the object that those skilled in the art study always.
Utility model content
The utility model provides the rotovator rotary blade that a kind of structure is simple, long service life, performance of loosening the soil are good.
A kind of rotovator rotary blade, comprise blade and connect the cutter pipe of blade, cutter pipe is connected with rotovator drive shaft, described cutter pipe periphery is connected with upper and lower two set of blades, each set of blades is equipped with four the 90 degree blades intersected, improve the fragmentation ability of blade for soil by the change of knife number and angle, improve efficiency of digging; Described cutter pipe is provided with two connecting holes through center, two connecting holes connect main shaft by quick clamping device, quick clamping device comprises the bearing pin being each passed through two connecting holes, main shaft, bearing pin one end connects an end of semicircle snap ring by torsion spring, and the other end is connected the other end of semicircle snap ring.This kind of quick clamping device connects cutter pipe and main shaft by pin shaft structure, and the coupling mechanism force of the semicircle snap ring generation adopting torsion spring to connect, holds cutter pipe and main shaft tightly and reaches quick-clamping object between rotary blade and main shaft.
Four blades in described each set of blades, two blades on same straight line are a pair, and wherein a pair blade cutter head bends all downwards, and another all upwards bends blade cutter head, more effectively smash soil by different cutter head overbending directions, increase soil oxygen content.
Be provided with flange as the preferred semicircle snap ring of structure away from one end of torsion spring, help semicircle snap ring to unclamp bearing pin, improve clamping efficiency further.
Described semicircle snap ring comprises upper and lower two semicircular ring, is connected between two semicircular ring by connecting ring, reaches by two semicircular ring structures the technical purpose adding bearing pin.
The utility model connects cutter pipe and main shaft by pin shaft structure, and the coupling mechanism force of the semicircle snap ring generation adopting torsion spring to connect, holds cutter pipe and main shaft tightly and reaches quick-clamping object between rotary blade and main shaft.
Accompanying drawing explanation
Be illustrated in figure 1 the utility model rotovator rotary blade perspective view;
Be illustrated in figure 2 the utility model rotovator rotary blade quick clamping device perspective view.
Embodiment
A rotovator rotary blade as shown in Figure 1, 2, comprise blade 2 and connect the cutter pipe 1 of blade 2, cutter pipe 1 is connected with rotovator drive shaft, and cutter pipe 1 periphery is connected with upper and lower two set of blades, each set of blades is equipped with four the 90 degree blades 2 intersected.Cutter pipe 1 is provided with two connecting holes through center, two connecting holes connect main shaft by quick clamping device 3, quick clamping device 3 comprises the bearing pin 4 being each passed through two connecting holes, main shaft, bearing pin 4 one end connects an end of semicircle snap ring 5 by torsion spring 6, and the other end is connected the other end of semicircle snap ring 5.Semicircle snap ring 5 is provided with flange 7 away from one end of torsion spring 6.As the preferred structure of semicircle snap ring clamping bearing pin, semicircle snap ring 5 comprises upper and lower two semicircular ring, is connected between two semicircular ring by connecting ring, two semicircular ring clamping bearing pins 4.
Four blades 2 in each set of blades, two blades 2 on same straight line are a pair, and wherein a pair blade cutter head bends all downwards, and another all upwards bends blade cutter head.
The foregoing is only an embodiment of the present utility model, not to the restriction of this case design, all equivalent variations done according to the design key of this case, all fall into the protection domain of this case.
