Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figures 1 to 8: present embodiment discloses a kind of flexible-belt grounding type precision seed metering devices: including motor control
It device 1 processed, rack 7 and is connected to the motor 2 of rack 7, stamp kind wheel 3, pore area 4, driven wheel, kind box 6, fills kind of a wheel 8, motor control
Device 1 connects motor 2 for controlling the rotation of motor 2, includes revolving speed, steering, start-up and shut-down control, motor control assembly 1 can be used existing
There is one of technology, need to only reach the work purpose of the present embodiment motor 2.
Motor 2 power output axis connection stamp kind wheel 3 driving stamp kind wheel 3 rotation, pore area 4 connection stamp kind wheel 3, driven wheel and
Kind of a wheel 8 is filled, the lower opening of 8 connection kind box 6 of kind of wheel is filled, stamp kind wheel 3 is equipped with stamp kind protrusion 31, and pore area 4 is schemed equipped with through-hole 41(
7) wheel 8, is filled kind to be equipped with type hole 81 and fill kind of a wheel boss 82, rack 7 is equipped with rack through slot 71, when pore area 4 connect stamp kind wheel 3, from
Driving wheel and when filling kind wheel 8, the connection stamp kind of through-hole 41 protrusion 31, type hole 81 and fills kind of a wheel boss 82.Stamp kind wheel 3 is driving wheel, is used
In drive hole band 4 and fill 8 rotation of kind of wheel.
In conjunction with Fig. 3 to Fig. 5: the vertical cross-section (filling kind of a radial section for wheel 8) of kind box 6 is sector, and kind box 6 is additionally provided with shield kind
Plate 62, there are two seeds protecting plates 62, and two seeds protecting plates 62 are separately connected type hole 81, and the effect of seeds protecting plate 62 is type hole 81 in order to prevent
Interior seed shedding causes seed to cannot be introduced into through-hole 41, to can not sow.Kind box 6 is additionally provided with clear kind of plate 61, clear kind of plate
61 preferably there are two, be set to the inside of kind of box 6, and be respectively arranged at the both sides of through-hole 41, the effect of clear kind of plate 61 is two
Between a clear kind of plate 61 Formation cross-section be it is fan-shaped fill kind of a region, the axial width filled between kind of region is (along filling kind of 8 sides of wheel
To) it is much smaller than the axial width of two kinds of boxes 6, therefore can more easily enter in the seed filled in kind of region to type hole 81
Among, and reach and fill kind of a region front end (the steering end for filling kind wheel 8), and is not filled with the seed of type hole 81 temporarily with filling kind of wheel 8
It rotates to wait in the front end for filling kind of region and be again introduced into type hole 81, increase the probability that seed enters to type hole 81, promoted
Seed-filling rate.
As shown in Figure 8: filling kind of a wheel boss 82 has two rows, and type hole 81 is set to two rows and fills between kind of wheel boss 82.
Specifically, driven wheel includes upper driven wheel 73 and lower driven wheel 51, rack 7 is equipped with framework pillar 72, framework pillar
72 upper end connects upper driven wheel 73.
In conjunction with Fig. 1 and Fig. 2: pore area 4 loosens in order to prevent, and driven wheel is additionally provided with the tensioning dress of the pore area for being tensioned pore area 4
Set, pore area tensioning apparatus include end plate 74, under driven wheel support 75, lower driven wheel wheel shaft 51 and adjusting screw rod 52, end plate 74 and
Under driven wheel support 75 be all connected to rack 7, the both ends of lower driven wheel wheel shaft 51 are all connected with adjusting screw rod 52, and adjusting screw rod 52 is logical
Cross nut connection board 74.Rotating nut realizes the transverse shifting of adjusting screw rod 52, and lower the lateral of driven wheel wheel shaft 51 is driven to move
It is dynamic, it realizes the variation of lower driven wheel 5 and stamp kind wheel 3 and 73 wheelbase of upper driven wheel, realizes the tensioning or release of pore area 4.
Destroy seed or damage pore area 4 in order to prevent, the stamp kind protrusion 31 of the present embodiment and to fill kind of a wheel boss 82 be round
Bore boss structure.
The material of pore area 4 is PVC, is unlikely to deform after PVC material processing through-hole 41, and have certain elasticity, can
Seed to be sowed is held on inside through-hole 41 by elasticity and frictional force.
The type hole 81 of specific the present embodiment has a circle, and stamp kind protrusion 31 has three circles.
When work, seed to be sowed should be screened first, rejecting be relatively large in diameter, lesser seed, be conducive to mention
Rise seeding accuracy.Then suitable pore area 4 is selected, selection principle is that the geometric dimension of seed to be sowed can be in 41 phase of through-hole
Match, the lower surface of rack 7 is close to ground to be sowed, can be avoided the height of seeds fall, seed is avoided to spring back, influences to broadcast
Kind precision.
Then strip sowing kind seed is put into the inside of kind of box 6, starts motor 2 and pore area 4 is driven to rotate, driving rack 7 is pasted
Ground to be closed to drive at a constant speed, 8 rotation of kind of wheel is filled in the drive of pore area 4, is filled in kind of 8 rotation processes of wheel, and seed enters to the inside of type hole 81,
Under the protection of seeds protecting plate 62 and type hole 81, the direct via through holes 41 of the lesser seed of section diameter are fallen down, the bigger seed of diameter
The inside of through-hole 41 is entered to, and as pore area 4 rotates, when pore area 4 to stamp kind wheel 3, if the seed inside through-hole 41
It does not fall off still, will be fallen under the action of stamp kind protrusion 31 by stamp, complete clear kind for pore area 4.For temporarily can not
The seed inside type hole 81 is entered to, then can wait and be again introduced into type hole 81 in the front end for filling kind of region, increase seed
The probability of type hole 81 is entered to, seed-filling rate is promoted.
The present invention is able to ascend the accuracy of sowing, and structure is simple, compact, cost is relatively low.
The above is only the preferred embodiment of the present invention, it is noted that those skilled in the art are come
It says, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations are also answered
It is considered as protection scope of the present invention.
