Abstract
The invention discloses a device for cutting straws, throwing straws and loosening soil, which is very convenient to operate. The device comprises a tool apron and a blade arranged on the tool apron, wherein a convex ring is arranged on the outer side surface of the tool apron; the inner pore radius of the convex ring is greater than a distance from the slot bottom of a spline slot in the tool apron to the shaft center; a clamping slot is formed in a position, corresponding to the spline slot, on the convex ring; shaft slots are formed in two opposite surfaces of the clamping slot; a spring hole is formed in the bottom of the clamping slot; clamping teeth are embedded into the clamping slot; rotary shafts are positioned in the shaft slots; the clamping teeth are in clearance fit with the clamping slot; a rotary cover is in rotary fit with the convex ring. During mounting, the rotary cover is rotated anticlockwise, so that the clamping teeth are jacked by the spring until the bottoms of the clamping teeth are lifted to ensure that the tool apron smoothly penetrates into the spline shaft. When the tool apron is moved to a set position, the rotary cover is rotated anticlockwise, so that the spring is retracted and the clamping teeth are pressed back until the bottoms of the clamping teeth move towards the shaft center; the spline shaft is clamped, so that the tool apron is firmly fixed on the spline shaft until the rotary cover does not rotate.
Description
Technical field
The present invention relates to a kind of domestic appliance, particularly a kind of stalk of cutting of sower gets rid of stalk loosening device.
Background technology
Owing to there being the foreign material such as stalk, weeds of last year in soil, impact sowing and seed sprouting, for removing these foreign material, the stalk of cutting having now sower to be provided with integrative-structure specially gets rid of stalk loosening device, be made up of tool rest and blade, blade is contained on tool rest, and tool rest center is spline axis hole, and this splined shaft borehole jack is on the splined shaft of sower.When splined shaft rotates, band knife section rotates, and is played the effect of digging, cut stalk and getting rid of stalk by blade.It can effectively clear up seeding belt stalk, weeds and chesson and not spoiled soil soil moisture content, therefore plants bed and fertile bed quality is improved, and is conducive to the germination of seed and emerges.But this is cut stalk and gets rid of stalk loosening device and be mounted on splined shaft, therefore, the spline axis hole at tool rest center and splined shaft are matched in clearance, easily movement in use procedure, are not easily fixed up in position, when needing to adjust the interval between tool rest, when changing different line-spacings, need dead knife seat to put motionless, but existing sower does not also have special purpose device, just replace with devices such as some simple pipe collars, operate inconvenience.
Summary of the invention
The object of this invention is to provide one to operate and conveniently cut stalk and get rid of stalk loosening device.
Technical scheme of the present invention is: comprise tool rest and be contained in the blade on tool rest, described tool rest lateral surface is provided with bulge loop, the internal bore radius of this bulge loop is greater than the distance of bottom land to axle center of tool rest upper spline groove, on bulge loop, corresponding spline position is provided with draw-in groove, two opposite faces of this draw-in groove are provided with axial trough, the bottom of draw-in groove is provided with spring eye, in this spring eye, spring is housed, latch two sides are provided with rotating shaft, latch is embedded in draw-in groove, rotating shaft is arranged in axial trough, latch and draw-in groove matched in clearance, spiral cover coordinates with bulge loop turn, latch the inner and spring contact, latch outer end contacts with spiral cover medial surface.
Described tool rest can adopt the parallel-connection structure of two same units.
The outer rim of described spiral cover is evenly equipped with jack.
The profile of described spiral cover is positive six prismatic structure.
Be provided with bulge loop, draw-in groove and latch in the present invention, latch is arranged in draw-in groove, and spiral cover coordinates with bulge loop turn, and latch the inner and spring contact, latch outer end contacts with spiral cover medial surface.Therefore, when mounted, counterclockwise turn spiral cover, makes latch by spring jack-up, ensures that tool rest can penetrate in splined shaft smoothly until lift bottom latch.When mobile tool rest is to the position set, screw spiral cover clockwise, the medial surface compressing latch of spiral cover, make spring retraction and latch is pushed back, until move to axle center bottom latch, clamping splined shaft, tool rest is tightly fixed on splined shaft, and spiral cover can not again till turn.Whole operating process is fast very convenient, only needs turn spiral cover to complete.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail, but does not form any limitation of the invention.Shown in Fig. 1 to Fig. 4, the blade that the present invention includes tool rest 1 and be contained on tool rest 1, described tool rest 1 lateral surface is provided with bulge loop, the internal bore radius of this bulge loop is greater than the distance of bottom land to axle center of tool rest 1 upper spline groove, on bulge loop, corresponding spline position is provided with draw-in groove, two opposite faces of this draw-in groove are provided with axial trough, the bottom of draw-in groove is provided with spring eye, spring 4 is housed in this spring eye, latch 3 two sides are provided with rotating shaft, latch 3 is embedded in draw-in groove, rotating shaft is arranged in axial trough, latch 3 and draw-in groove matched in clearance, spiral cover 2 coordinates with bulge loop turn, latch 3 the inner contacts with spring 4, latch 3 outer end contacts with spiral cover 2 medial surface.During installation, first counterclockwise turn spiral cover 2, until lift bottom latch 3, latch 3 around the shaft to inner rotary, ensures that tool rest 1 can penetrate in splined shaft smoothly under the promotion of spring 4.Then tool rest 1 is penetrated splined shaft, and adjust the position of tool rest 1 to setting, screw spiral cover 2 clockwise again, the medial surface compressing latch 3 of spiral cover 2, latch 3 Compress Spring 4 also inwardly rotates around the shaft, until move to axis direction bottom latch 3, finally clamp splined shaft, tool rest 1 is tightly fixed on splined shaft can not be moved.Whole operating process is fast very convenient, only needs turn spiral cover 2 to complete.Fig. 5 is the structural representation of latch 3, and Fig. 6 is the structural representation of spiral cover 2.Tool rest 1 can be single tool rest 1 structure, also can adopt two tool rest 1 structures arranged side by side.The outer rim of spiral cover can arrange jack, insert to facilitate inserted link instrument and rotate, more laborsaving.Also the profile of spiral cover can be arranged to positive six prisms, with tool operations such as convenient wrench.
