Planter 2 is set, and planter 2 includes bracket 21, front driving wheel 22, ditching device 23, seeding apparatus 24 and covering device
25.Graduated scale is posted on suspension arrangement 1, planter 2 can change different sowing line-spacings, realize row according to line-spacing difference
Away from adjustable.
As shown in Figure 1, there are six the quantity of planter 2.A part of the sowing mechanism as a whole of planter 2,
The transaction capabilities of monomer directly determine the operation effectiveness of complete machine.Planter 2 uses precision drilling, fully achieves fine grain crop
The precision drilling of seed.As shown in Figures 2 and 3, planter 2 is arranged by feeler mechanism 3 and back-moving spring 4 in suspension arrangement 1
On, feeler mechanism 3 is parallelogram four-bar linkage, and the adjacent both ends of feeler mechanism 3 are arranged on planter 2, in addition
Adjacent both ends are arranged on suspension arrangement 1, and one end of back-moving spring 4 is arranged on planter 2, other end setting is filled in suspension
It sets on 1.The feeler mechanism 3 is under the action of back-moving spring 4, during actual job, soil layer height is followed to float up and down, real
The now profiling of entire planter 2.Under the premise of guaranteeing that one end is fixed, the other end floats back-moving spring 4, realizes planter
Integrated profiling, facilitate machine to be applicable in different plot environment.
As shown in Figures 2 and 3, bracket 21 includes the backplate 211 of a pair of opposing, is equipped with three side by side between two backplates 211
Root connecting shaft 212, front driving wheel 22, seeding apparatus 24 and rear press wheel 26 are respectively provided in connecting shaft 212.
As shown in figure 4, front driving wheel 22 includes roller 221 and a pair of of rolling piece 222, roller 221 is rotatably provided in bracket 21
Front end lower section that is upper and being located at bracket 21；Roller 221 is located between two rolling pieces 222, and the side of rolling piece 222 is zigzag, rolls piece
222 side is exactly the rolling surface of the front driving wheel 22, increases ground grip ability, is easy to be suitble to a variety of rough soils.It broadcasts
During kind machine advances, two rolling pieces 222 and ground face contact, so that the rolling of front driving wheel 22 be made to advance.The material of front driving wheel 22
It is nylon material, wearability is strong, and plasticity is high, is unlikely to deform.
As shown in Figures 3 and 5, the setting of ditching device 23 is on the stent 21 and positioned at the rear of front driving wheel 22.Trench digging dress
Setting 23 includes adjustable column 232, shovel piece 231 and antiwind ring 233.Adjustable column 232, shovel piece 231 and antiwind ring 233 welding and
At belonging to weldment.Shovel piece 231 is connect by adjustable column 232 with bracket 21, and adjustable column 232 is long bolt, can be grown by adjusting
Screw rod changes ditching depth, realizes that depth is adjustable.Shovel piece 231 is wing shovel type structure, and shovel tip is sharp.Shovel wing is smooth, convenient for breaking ground
With suitable soil.Antiwind ring 233 is arranged at the shovel tip of shovel piece 231, and the antiwind ring 233 is from bottom to top, from the front to the back gradually
The top rear of outreach, antiwind ring 233 is equipped with opening, and antiwind ring 233 at any time moves the sundries such as weeds in operation process
It opens, part sundries removes after the opening accumulation of antiwind ring 233, and sundries is avoided to influence 23 ditching operation of ditching device.
As shown in Fig. 3, Fig. 6, Fig. 7 and Fig. 8, seeding apparatus 24 is arranged on the stent 21, and after ditching device 23
Side.Seeding apparatus 24 includes grain conductor 241, kind box 242, shaft 243, idler wheel 244 and baffle 245.The setting of grain conductor 241 is being planted
At the bottom end opening of box 242, shaft 243 is rotatably provided in kind of box 242, and idler wheel 244 is fixed in shaft 243, idler wheel
244 side is equipped with the kind hole of several invaginations, and the size for planting hole is determined by fine grain crop seed, is wanted according to the plantation of crop
It asks, it is possible to visualise the sowing requirement in more of single cave simple grain, single cave and more of more caves reaches the adjustable effect of spacing in the rows.The design of kind hole
Ovalisation, corner lead angle design the size in ellipse kind hole according to the measurements of the chest, waist and hips size of crop seed；According to surviving for seed
Rate designs the depth of type hole, so that it is determined that the seeding method of more of single cave simple grain, single cave and more of more caves, realizes seeding method
Maximization adjustment.Baffle 245 is to folded plate, and the rear end of baffle 245 is bonded with idler wheel 244, and the front end of baffle 245 is opposite sets
It the scraper plate set and is bonded with idler wheel 244, shaft 243 is arranged on the bearing of two backplates 211, and bearing plays the work of fixed limit
With 243 one end of shaft connection sowing head sprocket, which is hexagonal prisms, is matched with idler wheel 244.
The adjusting of spacing in the rows can be adjusted by two ways.One kind is to change transmission ratio to realize, front driving wheel 22 is transported
Dynamic that power is passed to shaft 243 by chain, shaft 243 drives idler wheel 244 to realize seeding process.In power transmission process
In, it is provided with square hole inside idler wheel 244, can be replaced at any time.The number of teeth is differed from 16~20 teeth, by change its number of teeth number, it is real
The change of existing transmission ratio realizes the change of sowing spacing in the rows, so that the seeder seeding spacing in the rows is more smart to change sowing revolving speed
Really, while convenient for constructor it operates, ensure that the survival rate of seedling and the maximum production of later period crop to the full extent.It is another
Mode is to change the distributed dimension in the kind hole on idler wheel 244, according to the size that spacing in the rows requires, in conjunction with the diameter of front driving wheel 22,
Cooperate transmission ratio, changes the distributed quantity in kind of hole, realize the adjustment of spacing in the rows.By replacing different idler wheels 244, solid not homophyletic
Away from variation adjustment.Two kinds of adjustment mode more convenient and quickers can flexibly be used according to the needs of specific actual job process.
As shown in figure 3 and 9, covering device 25 is arranged on the stent 21, and is located at the rear of seeding apparatus 24.Covering device
25 include earthing fixed frame 251, bent plate 252, earthing pressure spring and trailing bar 253, and earthing fixed frame 251 is fixed at bracket 21
On.Bent plate 252 is rotatably provided on earthing fixed frame 251, and one end of bent plate 252 passes through earthing pressure spring and earthing fixed frame 251
Connection, the other end and trailing bar 253 connect, and the front end of trailing bar 253 is equipped with the arc of indent.
In addition, as shown in figure 3, the planter 2 of the application further includes rear press wheel 26, rear press wheel 26 and front driving wheel
22 is identical.
Power transmission process in the application is: the Transport Machinery such as tractor suspension traction planter 2 advances, before causing
Driving wheel 22 advances, and power is transmitted to seeding apparatus 24, front driving wheel 22 and sowing driving wheel by chain conveyer by front driving wheel 22
Holding moves synchronously, and completes seeding process, and rear press wheel 26 is driven wheel, in the case where entire planter 2 advances, rear town
Pinch roller 26 is advanced by traction.
Above with reference to preferred embodiment, invention has been described, but protection scope of the present invention is not restricted to
This can carry out various improvement to it and can be replaced wherein with equivalent without departing from the scope of the invention
Component, as long as be not present structural conflict, it is mentioned in the various embodiments items technical characteristic can combine in any way
Get up, and any reference signs in the claims should not be construed as limiting the involved claims, no matter comes from which point
It sees, the present embodiments are to be considered as illustrative and not restrictive.Therefore, any to fall within the scope of the appended claims
All technical solutions be within the scope of the invention.
