Description

Four row potato seedling killing machines

Technical field

The utility model belongs to agriculture potato harvest machine technical field, is killed more particularly, to four row potatos of one kind Seedling machine.

Background technology

With potato staple food grain implementation, potatoes cultivated area increased year by year in recent years, and potato is Through becoming important grain dish dual-purpose crop, potato harvest machine equipment is very ripe at present but machine before potato harvest It is relatively low that tool kills seedling operating efficiency, and potato skin aging can be promoted by killing seedling operation, reduce elevating chain separator in harvest proceduse Broken skin is damaged caused by stem tuber, promotes the promotion of harvest quality；Meanwhile it kills seedling and can also reduce the failure of cropper separator Rate improves disintegrate-quality, reduces harvest loss, promotes the raising of efficiency of crop；In addition, mechanization kill seedling operation can also avoid because Applied chemistry kills seedling agent and pollution on the environment, therefore designs a kind of four row potato seedling killing machines.

Utility model content

The purpose of this utility model be for it is set forth above the problem of, provide it is a kind of it is adaptable, operation quality is high, performance Superior four rows potato seedling killing machine.

To achieve the above object, the utility model uses following technical proposals：The four row potato seedling killings of the utility model Machine, flail knife, ridge side are got rid of on the gearbox, hanging beam, transmission device, gauge wheel, shield, ridge by rack and in the rack Knife, furrow flail knife, cutter shaft, stationary knife, case, bifurcated plate, skylight board composition；Tractor is connected by trifilar suspension beam with rack It connects, tractive force and operation power is provided for complete machine；Lower margin is fixedly mounted on the bottom of rack, plays a supportive role；Transmission system is pacified It is connected mounted in the left side of rack with gear-box；Power is transferred on cutter shaft by V belt translation, cutter shaft makees high-speed rotation flail knife It is hinged on by axis pin and tool apron on cutter shaft；Seedling killing machine is located at the top of stent, mainly by case, stationary knife, skylight board and bifurcated Plate forms, and on the inside of case on corresponding ridge and furrow position sets stationary knife, matched with stationary knife is three kinds of flail knives, flail knife on ridge, Flail knife is arranged in order in ridge side flail knife, ridge, and intermediate bifurcated plate is arranged on the downside of stationary knife on ridge, and skylight board is located at shield upper end.

As the preferred embodiment of the utility model, the knife group structure is flail knife and stationary knife work compound, and stationary knife is located at On shield, flail knife is located on tool apron, arrangement mode of three kinds of different types of flail knives on rotor for staggeredly equidistant arrangement, tool apron It is welded on cutter shaft, carries out high speed rotation with three kinds of flail knives of movement of cutter shaft, seedling operation is killed in completion.

As the preferred embodiment of the utility model, the seedling killing machine shield structure device, mounted on frame upper end, mainly by Case, stationary knife, skylight board and bifurcated plate composition, case use off-centre operation arcuate structure, from the import of stem seedling to outlet flail knife and cover Gap between shell gradually increases, and bifurcated plate is arranged on the downside of stationary knife on ridge, shedding to play and lead to the stem seedling smashed and weeds To effect, skylight board is set, opening it when clay or serious winding, which occurs, in seedling killing machine is cleared up, and reduces machine on shield Failure rate.

Due to the adoption of the above technical scheme, four rows potato seedling killing machine provided by the utility model is compared with prior art It has the advantages that：

The four rows potato seedling killing machine working width is big, can improve and kill seedling operating efficiency, using the knot of three kinds of flail knife groups Structure design can effectively solve to smash that length qualification rate is poor, height for the stubble left height and asks with potato rate is high existing for existing seedling killing machine Topic；Seedling killing machine shield is act as：Security protection prevents the stem impacted under cover seedling, weeds and soil sundries is dished out and airborne dust, matches somebody with somebody Flail knife is closed further to smash stem seedling, weeds etc..

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and detailed description：

As shown in Figure 1, Figure 2, Figure 3 shows, four row potato seedling killing machines mainly include rack 1 and the biography in the rack 1 It is dynamic device 3, shield 2, shaft coupling 4, gearbox 5, hanging beam 6, cutter shaft 7, flail knife 8 on ridge, ridge side flail knife 9, flail knife 10 in ridge, fixed Knife 11, intermediate bifurcated plate 12, land wheel 13, lower margin 14, case 15 and skylight board 16 form；Lower margin 14 is fixedly mounted on rack 1 Bottom plays a supportive role；Hanging beam 6 is connected with tractor positioned at the top of rack；Gearbox 5 is located at hanging beam centre position； Shaft coupling 4 is connected；Transmission device 3 is located at the left side of rack；It is cutter shaft 7 to be connected with 3 lower part of transmission device；Flail knife on ridge 8th, ridge side flail knife 9, flail knife 10 is hinged on cutter shaft 7 in ridge, do with cutter shaft 7 and rotate at a high speed；On the corresponding ridge in 15 inside of case and ridge Ditch position sets stationary knife 9, and the downside of flail knife 8 on ridge is arranged on intermediate bifurcated plate 12.

As the preferred embodiment of the utility model, as shown in Figure 1, flail knife 8, ridge side flail knife on ridge in the flail mechanism 9th, in ridge flail knife 10 successively staggeredly etc. row discharge, be fixed on by tool apron on cutter shaft 7, when transmission device 3 with movable arbor 7 do at a high speed During rotary motion, seedling operation is killed in completion.

As the preferred embodiment of the utility model, as shown in Figure 1, Figure 3, the shield structure by intermediate bifurcated plate 12, Case 17, stationary knife 11, skylight board 16, case 17 are in eccentric arc structure, and on the corresponding ridge in 17 inside of case and furrow position is set Stationary knife 11 is put, intermediate bifurcated plate 12 is arranged on the downside of stationary knife 8 on ridge, and skylight board 16, skylight board 16 are placed above case 17 Top, which is provided with spacious hole and prevents from blocking, influences work efficiency.

Illustrate the operation principle of the utility model below, the bottom that lower margin 14 is fixedly mounted on rack 1 plays a supportive role；It kills Seedling machine is mounted using trifilar suspension mode by hanging beam 6 and tractor, and tractor provides tractive force and operation power, power warp Gearbox 5 is sent to by shaft coupling 4 in actuator system 3, is transferred to short axle 7 by V belt translation, flail knife is cut with scissors by tool apron It is connected on rotor, during equipment operation, high-speed rotating flail knife interrupts stem seedling and weeds, and the stem seedling, weeds after interrupting are by flail knife It brings on shield shell 15, and is further hit, cut under the collective effect of the stationary knife 11 set in flail knife, shield and shield shell It cuts, rub into broken section, finally shed by stem seedling mouth of dishing out to field.Gauge wheel 13 is located at the bottom of rack, plays support guide Effect；Case 15 coordinates flail knife further to smash cauline leaf and weeds.

The utility model can improve good potato seedling killing operating efficiency, operation quality, operation amplitude broad, easy to adjust, fortune The characteristics of row is reliable, stability is high.
