Description
Technical field
The utility model relates to agricultural machinery technological field, is specifically related to a kind of bridge breaker of miniature seeding machine.
Background technology
When miniature seeding machine was put the field operation of foreign material such as still having stubble, soil block prior to seeding in order, plough was blocked and lost efficacy and happen occasionally, and needs manually auxiliary unimpeded after the obstruction, labor intensive man-hour, reduced production efficiency and operation quality.Solving anti-blocking key issue is the both sides that foreign material such as plough the place ahead stalk, weeds, soil block are pushed to them timely and effectively the sowing band, thereby alleviate the load of plough, prevent the blockage problem of plough, whether possess good anti-blocking performance, become one of key factor that influences miniature seeding machine production efficiency and seeding quality.
At present, domestic anti-block apparatus research mainly concentrates on the no-tillage seeding machine, the general structure more complicated of these anti-block apparatus, and consumed power is bigger, is not suitable for miniature seeding machine.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of simple in structure, power consumption is little, the miniature seeding machine bridge breaker that anti-blocking performance is good, be with foreign material such as soil block, stalk to push away kind of a bed sowing to reach, it is smooth once more to plant a soil simultaneously, creates good sowing environment, guarantees the purpose of the water furrow planting quality of plough.
The utility model technical solution problem adopts following technical scheme:
The utility model miniature seeding machine bridge breaker is made up of support, link and anti-blocking panel assembly, and its design feature is:
Described support comprises a longeron, and the bottom of longeron is a "T"-shaped fixedly connected crossbeam, and an axle bed is set on crossbeam, and screw axis is bearing on the axle bed, and screw axis is provided with torsion spring;
Described link comprises the U-shaped pulling seat, fixedly installs a gear shaft at the front end of U-shaped pulling seat, and the biside plate movable set of U-shaped pulling seat is at the two ends of screw axis, and an end of torsion spring is supported on the crossbeam, the other end is supported on the gear shaft; Be set with the transverse slat seat at the middle part of U-shaped pulling seat, the afterbody of U-shaped pulling seat is by the stringer board seat axis that fixedly suspends, and the two ends of axis are set with stage clip;
Described anti-blocking panel assembly comprises the anti-closure plate of " eight " shape setting of a pair of being, and the front end of anti-closure plate is to be connected on the transverse slat seat by hold-doun nut around axle; The afterbody of a pair of anti-closure plate is set in the two ends of axis, and is that stage clip with suit on the clamping nut of axis outer end and the axis is fixed.
The design feature of the bridge breaker of the utility model miniature seeding machine also is:
Described anti-closure plate is that rectangle and its outer lower portion are cutting edge with the front portion.
The front end of described anti-closure plate is one in front and one in back setting, and leaves the gap each other.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model volume is little, in light weight, rational in infrastructure, use is flexible, conveniently is mounted on the miniature seeding machine, can enhance productivity and operation quality;
2, in the utility model two separately the anti-blocking panel assembly of independently working improved work quality and efficient, anti-closure plate adopts blade shape, when pushing foreign material, also have concurrently loosen the soil, effects such as hack, smooth kind bed, reduce the resistance of foreign material to anti-closure plate, reduce the power consumption of sower, the environment of creating for plough work;
3, anti-closure plate is one in front and one in back installed in the utility model, has effectively solved the bridge breaker Problem of Failure; Adopt the anti-closure plate of clamping nut and stage clip adjustment to push the angle of foreign material, can satisfy the differently thickness requirement of condition propelling movement foreign material, guarantee work quality;
4, being provided with of torsion spring and stage clip is beneficial to bridge breaker smoothly by obstacles such as soil block, root stubbles in the utility model, thereby prolongs the service life of bridge breaker.
Description of drawings
Fig. 1 is the utility model perspective view;
Fig. 2 is the utility model bridge breaker and sower connection diagram;
Fig. 3 is the utility model plan structure schematic diagram.
Number in the figure: 1 support; 2 links; 3 anti-blocking panel assemblies; 4 plough frames; 11 longerons; 12 crossbeams; 13 axle beds; 14 screw axis; 15 torsion springs; 21 is the U-shaped pulling seat; 22 gear shafts; 23 transverse slat seats; 24 stringer board seats; 25 stage clips; 26 clamping nuts; 27 axis; 31 around axle; 32 anti-closure plates.
Embodiment
Present embodiment is made up of support 1, link 2 and anti-blocking panel assembly 3.
Fig. 1, shown in Figure 2, support 1 comprise a longeron 11, and the bottom of longeron 11 is a "T"-shaped fixedly connected crossbeam 12, and an axle bed 13 is set on crossbeam 12, and screw axis 14 is bearing on the axle bed 13, and screw axis 14 is provided with torsion spring 15;
Fig. 1, shown in Figure 3, anti-blocking panel assembly 3 comprise the anti-closure plate 32 of " eight " shape setting of a pair of being, and the front end of anti-closure plate is to be connected on the transverse slat seat 23 by hold-doun nut around axle 31; The afterbody of a pair of anti-closure plate 32 is set in the two ends of axis 27, and is that stage clip 25 with suit on the clamping nut 26 of axis 27 outer ends and the axis 27 is fixed.
In concrete the enforcement, the corresponding structure setting also comprises:
During anti-blocking operation, bridge breaker is connected to the positive front end of seed-furrow opener frame 4, adjusts the position-controllable system bridge breaker of support longeron and the height on ground up and down by support longeron 11; Before the sower operation, according to the situation in sowing field, arrangement back, can regulate the propelling movement foreign material angle theta of anti-blocking plate, thereby guarantee bridge breaker consumed power minimum by twisting clamping nut 26; Concrete operations rotate anti-closure plate for twisting clamping nut 26 around the shaft, determine the propelling movement foreign material angle theta of suitable anti-closure plate; The angle β of bridge breaker and vertical direction guarantees by torsion spring; When the sower operation, the mind-set both sides push foreign material in two anti-closure plate natural seeding kind bands.Before the anti-simultaneously closure plate, the bottom cutting edge structure can to soil block, the stalk of process loosen, hob broken; Two anti-closure plates are " eight " word arrangement; The ordinary circumstance foreign material are given the elastic force of the active force of anti-closure plate less than stage clip and torsion spring, anti-closure plate pushes the angle of foreign material and the angle of bridge breaker and vertical direction can not change, and when running into obstacles such as bulk pan soil or root stubble when anti-closure plate, anti-closure plate can't be with its chopping or crushing, barrier puts on the elastic force of the power of anti-closure plate greater than stage clip and torsion spring, this is, when the elastic force of horizontal applied force greater than stage clip, the propelling movement foreign material angle theta of anti-closure plate will change, anti-closure plate diminishes propelling movement foreign material angle theta around changeing in axially, slip over barrier smoothly and help anti-closure plate, slip over behind the barrier because the screen resilience of stage clip prevents that the propelling movement foreign material angle theta of closure plate is recovered voluntarily; When the elastic force of vertical active force greater than torsion spring, the angle β of bridge breaker and vertical direction will become greatly, drives bridge breaker and lifts, and clears the jumps smoothly and help bridge breaker, owing to the effect of torsion spring screen resilience, the angle β of bridge breaker and vertical direction is recovered after clearing the jumps.
