Abstract
The invention discloses a rotary blade for a rotary cultivator. The rotary blade for the rotary cultivator comprises blade bodies and a blade tube connected with the blade bodies. The blade tube is connected with a driving spindle of the rotary cultivator, the periphery of the blade tube is connected with an upper blade body set and a lower blade body set, and each blade body set is provided with four blade bodies which intersect at the angle of 90 degrees. The blade tube is provided with two connecting holes penetrating through the center of the blade tube, and the two connecting holes are connected with the spindle through a rapid clamping device. The rapid clamping device comprises hinge pins which penetrate through the two connecting holes and the spindle respectively, one end of each hinge pin is connected with one end of a semicircular clamping ring through a torsional spring, and the other end of each hinge pin is connected with the other end of the semicircular clamping ring in a matched mode. The blade tube is connected with the spindle through the hinge pin structure, the tight locking force generated by the semicircular clamping rings connected through the torsional springs is used for holding the blade tube and the spindle tightly, and thus the rapid clamping purpose between the rotary blade and the spindle can be achieved.
Description
Technical field
The present invention relates to a kind of cutter, specifically a kind of rotovator rotary blade.
Background technology
At present rotovator is the common equipment for ploughing, digging, and requires rotary blade soil to be had to depth of turning soil is large, degree of refinement is high, and connects the specification requirement such as soon of main shaft clamping speed.The connected mode of its rotary blade of existing rotovator and main shaft has mostly adopted bolt fastening structure, and this kind of connected mode not only loaded and unloaded trouble, and often occurs that along with using bolt looseness etc. affects the loosen the soil technical problem of performance of rotary blade.How to realize quick, the stable installation capability of rotary blade and raising is loosened the soil, the technical scheme of refinement efficiency is the object that those skilled in the art study always.
Summary of the invention
The invention provides a kind of simple in structure, long service life, rotovator rotary blade that the performance of loosening the soil is good.
A kind of rotovator rotary blade, comprise blade and the cutter pipe that connects blade, cutter pipe is connected with rotovator drive shaft, described cutter pipe periphery is connected with upper and lower two set of blades, in each set of blades, be equipped with four the 90 crossing blades of degree, variation by knife number and angle improves blade for the fragmentation ability of soil, improves the efficiency of digging; Described cutter pipe is provided with two through the connecting hole at center, two connecting holes connect main shaft by quick clamping device, quick clamping device comprises the bearing pin that passes respectively two connecting holes, main shaft, bearing pin one end connects an end of semicircle snap ring by torsion spring, be connected the other end of semicircle snap ring of the other end.This kind of quick clamping device connects cutter pipe and main shaft by pin shaft structure, and adopts the coupling mechanism force of the semicircle snap ring generation of torsion spring connection, holds cutter pipe and main shaft tightly and reaches the quick-clamping object between rotary blade and main shaft.
Four blades in each described set of blades, two blades on same straight line are a pair of, wherein all bendings downwards of a blade cutter head, and another blade cutter head is upwards bending all, by different cutter head overbending directions, more effectively smash soil, increase soil oxygen content.
As the preferred semicircle snap ring of structure, away from one end of torsion spring, be provided with flange, help semicircle snap ring to unclamp bearing pin, further improve clamping efficiency.
Described semicircle snap ring comprises upper and lower two semicircular ring, between two semicircular ring, by connecting ring, connects, and by two semicircular ring structures, reaches the technical purpose that adds bearing pin.
The present invention connects cutter pipe and main shaft by pin shaft structure, and adopts the coupling mechanism force of the semicircle snap ring generation of torsion spring connection, holds cutter pipe and main shaft tightly and reaches the quick-clamping object between rotary blade and main shaft.
Accompanying drawing explanation
Be illustrated in figure 1 rotovator of the present invention rotary blade perspective view;
Be illustrated in figure 2 rotary blade quick clamping device perspective view for rotovator of the present invention.
Embodiment
A rotovator rotary blade, comprises blade 2 and the cutter pipe 1 that connects blade 2 as shown in Figure 1, 2, and cutter pipe 1 is connected with rotovator drive shaft, and cutter pipe 1 periphery is connected with upper and lower two set of blades, is equipped with four the 90 crossing blades 2 of degree in each set of blades.Cutter pipe 1 is provided with two through the connecting hole at center, two connecting holes connect main shaft by quick clamping device 3, quick clamping device 3 comprises the bearing pin 4 that passes respectively two connecting holes, main shaft, bearing pin 4 one end connect an end of semicircle snap ring 5 by torsion spring 6, be connected the other end of semicircle snap ring 5 of the other end.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, connects two semicircular ring clamping bearing pins 4 between two semicircular ring by connecting ring.
Four blades 2 in each set of blades, two blades 2 on same straight line are a pair of, wherein all bendings downwards of a blade cutter head, another blade cutter head is upwards bending all.
The foregoing is only one embodiment of the present of invention, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.
