Description
Technical field
The present invention relates to agricultural mechanical fields.
Background technique
China shallowly turned over rotary cultivator in many areas year after year, rotary tillage process, causes the shape between arable layer and subsoil
At one layer of hard, closed plough sole.The presence of plough sole influences to stretch under crop root, and venting and water permeable is unsmooth, to subsoil
Nutriment is transmitted to crop root and moisture impacts, to influence crop yield.One of settling mode is Subsoiler.
When Subsoiler, deep soil loosing shovel makes soil tearing, squeezes and disturb, to break plough sole, to improve the structure of soil, enhancing soil
Earth is retained and conserved soil moisture and drought-relief, waterlogging-preventing ability, to increase crop yield.But there are two large problems for subsoiling equipment: first is that operation resistance
Greatly, earth's surface is uneven after operation blocking, operation;Second is that soil can glue when the hack roller on equipment works under the conditions of clayed soil
It is attached on hack roller, influences roller tooth normal work, reduce hack effect.Meanwhile needing to carry out rotary tillage process after single Subsoiler,
The multiple of tractor works into ground, easily causes the secondary compaction of soil and reduces working efficiency.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of subsoiling rotary tillage hack combined soil preparing machines, and use can be improved in it
Service life and operation quality reduce operation resistance, guarantee agronomy production requirement, to be of great significance to crop yield is improved.
In order to solve the above technical problems, the technical solution used in the present invention is:
A kind of subsoiling rotary tillage hack combined soil preparing machine, including rotary tillage knife assembly, deep soil loosing shovel and the hack being arranged on the rack
Roller, hack roller include the outer hack tooth being staggeredly welded on cylindrical roller surface, and hack roller has self-cleaning structure: hack roller
Cylindrical roller is engraved structure roller, the hack tooth in engraved structure drums inside staggeredly welds;It is set between deep soil loosing shovel and rack
There is self-excitation percussion mechanism: including deep soil loosing shovel fixed cross beam, rack fixed cross beam, the fixed vertical beam of rack and Direct Travel elastic telescoping dress
It sets, deep soil loosing shovel fixed cross beam is fixed on the upper end of deep soil loosing shovel, and rack fixed cross beam is fixed on the lower end of rack, and solid with deep soil loosing shovel
Determine crossbeam to be correspondingly arranged up and down, the upper end of the fixed vertical beam of rack is fixed on the front end of rack fixed cross beam, the fixed vertical beam of rack
Lower end and the front end of deep soil loosing shovel fixed cross beam are hinged, Direct Travel elastic telescoping device and the fixed vertical beam correspondence setting of rack,
Direct Travel elastic telescoping device includes central spindle of the spring, spring, spring end cap, spring pre-tightening nut, spring pedestal and active pin,
Central spindle of the spring upper end is equipped with screw thread, and central spindle of the spring is equipped with longitudinal bar shape trench hole below screw thread, and central spindle of the spring lower end is fixed to be connected
Spring pedestal is connect, is perforated in the bottom of spring pedestal equipped with fixed pivot pin, the front-end and back-end of spring end cap sidewalls are symmetrically arranged with
Active pin perforation, spring are socketed on central spindle of the spring, and spring end cap penetrates bullet by central spindle of the spring upper end by the hole of its roof
Spring mandrel, and it is pressed against the upper end of spring, active pin sequentially passes through the active pin perforation of spring end cap sidewalls front end, spring
Longitudinal bar shape trench hole of mandrel and the active pin of spring end cap sidewalls rear end perforate spring being limited to spring end cap and spring
Between pedestal, spring pre-tightening nut is pressed by central spindle of the spring threaded upper ends and is covered in spring terminal, to generate pretightning force to spring;
Direct Travel elastic telescoping device is hinged by the rear end of its active pin and rack fixed cross beam, and fixed pivot pin passes through Direct Travel bullet
The fixed pivot pin perforation of power telescopic device is hinged with the rear end of deep soil loosing shovel fixed cross beam.
The present invention further improvement lies in that:
The specific structure of hack roller includes drum shaft, left end hack tooth fixing axle mounting disc, right end hack tooth fixing axle peace
Sabot and multiple hack tooth fixing axles, multiple hack tooth fixing axle left and right ends are separately fixed at the installation of left end hack tooth fixing axle
On disk and right end hack tooth fixing axle mounting disc, and circumferential circular row forms hollow out knot on the cylindrical surface using drum shaft as axle center
Structure roller, outer hack tooth are fixed in the hack tooth fixing axle of the position on the outside of relative to roller, and interior hack tooth is fixed on relatively
In in the hack tooth fixing axle of the position of drum inside.
Spring in Direct Travel elastic telescoping device includes inner spring and the outer spring that is socketed on the outside of inner spring, inner spring
It is oppositely oriented with outer spring.
Form the fixed vertical beam of deep soil loosing shovel fixed cross beam, rack fixed cross beam, rack and Direct Travel bullet of self-excitation percussion mechanism
Power telescopic device generally rectangular configuration.
The beneficial effects of adopting the technical scheme are that
(1) hack roller has self-cleaning structure: the cylindrical roller of hack roller is engraved structure roller, in engraved structure roller
Alternate internal welds interior hack tooth;When work, by outer hack tooth by soil primary crushing.Since cylindrical roller is engraved structure rolling
Cylinder, soil can be entered inside cylindrical roller by gap, so that cylindrical roller surface will not be adhered to.Into inside cylindrical roller
Soil carries out secondary hack under the action of interior hack tooth.Therefore, when working the invention avoids existing hack roller, soil adhesion
On cylindrical roller, influence roller tooth work normally the phenomenon that, and can to relatively large hack engraved structure drums inside into
Row second-time breakage improves hack effect.
(2) self-excitation percussion mechanism is equipped between deep soil loosing shovel and rack, it is harder to encounter quality during deep soil loosing shovel shovel ground
When soil, make spring-compressed, active pin carries out reciprocal shifting movement in longitudinal bar shape trench hole of central spindle of the spring, produces deep soil loosing shovel
Raw vibration passes to soil, and soil passes through after repeated multiple times shock loads, and the breakdown strength of itself declines, and then reduces
Tillage resistance;When deep soil loosing shovel shovel ground during encounter the foreign matters such as tree root and stone when, can play avoidance protect deep soil loosing shovel from
The effect of damage.The contracting movement of straight line bullet is carried out since Direct Travel elastic telescoping device is oriented to by central spindle of the spring, spring is avoided and exists
The power for favouring motion profile is generated when compression and rebound, so as to avoid hinged to Direct Travel elastic telescoping device upper and lower ends
The damage of part, improves service life;The length of longitudinal bar shape trench hole on central spindle of the spring simultaneously, guarantees that spring has been not in
Complete compressed state, guarantees the reliability of spring works.Spring in Direct Travel elastic telescoping device includes inner spring and set
The outer spring in interior spring outwards is connect, inner spring and outer spring are oppositely oriented, act on the torsion of spring end cap and spring pedestal
It offsets, avoids loosening after a period of work.
It can be improved service life and operation quality, reduces operation resistance, guarantees agronomy production requirement, thus to raising
Crop yield is of great significance.
