Abstract
The utility model discloses a straw shredding device which comprises a guide plate and a spiral cutting knife assembly. The guide plate is mounted at a discharge end of a straw pulling device of a straw harvester. An inlet is arranged on the upper portion of the guide plate, and a working groove is connected with the lower portion of the guide plate. The spiral cutting knife assembly is arranged in the working groove and comprises a main shaft driven by a power unit, and a spiral cutting knife mounted on the main shaft. The working groove is provided with a material dropping groove at the tail end of the spiral cutting knife. The straw shredding device integrates material conveying, feeding and shredding functions, greatly reduces the number of transmission components, lowers consumed power, reduces the size, lightens the weight, lowers manufacturing cost, and improves working reliability and working efficiency.
Description
Technical field
The utility model belongs to agricultural machinery technological field, particularly a kind of straw chopping apparatus.
Background technology
Present stalk harvester all is not equipped with shredding mechanism, the shortcoming of this type of stalk harvester is: stalk is after being chosen and being cut, directly be placed upside down between the field, to and be transported to specific shredding mechanism through artificial collection, just can shred, it requires greatly personnel, and inefficiency, cost requirement is high.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, high efficiency, cost requirement is low, can solve the stalk rear straw chopping apparatus problem of choosing, the stalk cutter sweep that namely integrate conveying, feed, shreds is applicable to and pulls out the stalk device and match.
A kind of straw chopping apparatus, described guide plate is installed in the discharge end that stalk harvester pulls out the stalk device, the top of described guide plate is import, the below is connected with work nest, be provided with described helical cut knife assembly in the described work nest, described helical cut knife assembly comprises the main shaft that is driven by power set and the spiral cutter that is installed on the described main shaft, and described work nest is provided with charging conduit at the end of described spiral cutter.
In the utility model, described guide plate comprises left guide plate and right guide plate, is provided with successively from top to bottom on the described left guide plate stalk oriented is dropped into gear stalk and terminal slide plate in the helical cut knife assembly of described work nest.
In the utility model, described main shaft also is fixed with cutting knife near described charging conduit place
In the utility model, described main shaft is installed in the work nest by bearing bracket stand and by chain wheel drive.
In the utility model, described main shaft is comprised of cone axis and cylinder axis, described spiral cutter comprises taper seat spiral cutter and face of cylinder spiral cutter, described main shaft two ends are that the cone axis mid portion is cylinder axis, the taper seat spiral cutter that stalk is played the feeding effect is installed on the described cone axis, the face of cylinder spiral cutter that stalk is played cutting and feeding effect is installed on the described face of cylinder.
In the utility model, the below of described charging conduit is equipped with collecting box.
Owing to adopt such scheme, the utility model is installed in the discharge end that stalk harvester pulls out the stalk device, pull out stalk device stalk out from stalk harvester and directly enter into this device, guiding by guide plate enters into the helical cut knife assembly stalk is smashed, fall into collecting box from charging conduit again, need not extra manual operation in the process, saved manpower; In addition, gear stalk and terminal slide plate play the effect that the stalk oriented is dropped into the helical cut knife assembly of described work nest, have prevented the phenomenon that stalk is rushed in guide plate; Cutting knife cuts off the stalk that is not cut off fully by spiral cutter, so that stalks cutting, easier falling outward by charging conduit joined in the collecting box; Described main shaft is comprised of cone axis and cylinder axis, cone axis makes spiral cutter soaring along taper seat, cylinder axis makes spiral cutter along the face of cylinder along liter, described spiral cutter is comprised of taper seat spiral cutter and face of cylinder spiral cutter, the taper seat spiral cutter plays the feeding effect to the stalk that imports, and face of cylinder spiral cutter plays cutting and feeding effect to the stalk that imports.
In sum, this device integrates conveying, feeds, shreds, and has greatly reduced driving member, has reduced power consumption, has reduced volume, has alleviated weight, has reduced manufacturing cost, has improved functional reliability and operating efficiency.
