Description
Technical field
The invention belongs to and lead the sower part field of planting and sowing, be specifically related to a kind of up-and-down reciprocating seeding unit that is applied to corn drill.
Background technology
At present, also increasing to the demand of precision metering device along with the improving constantly of seed quality.Precision metering device can be saved breeding, reduces cost; Without thinning, reduce labour intensity; The Precision Seeding field plant is evenly distributed, and reaches rational close planting, is beneficial to seedling growth.This technology has been widely used in intertillage crop such as program request corn, soybean.
Seeding unit generally is divided into two types: pneumatic type seeding unit and mechanical type seeding unit.The pneumatic type seeding unit has kind of shape is required advantages such as not strict, that adaptability strong, the seed damage is little, but its complex structure, body is heavy, power consumption is big, cost is high, generally is applied to large-scale sower.And the mechanical type seeding unit has simple in structure, advantages such as cost is low, convenient maintenance and replacement are occupied certain proportion in practical application, relatively are fit to miniature seeding machine.But at present the mechanical type seeding unit all exist strict to shape of the seed and size requirements, can't adapt to problems such as high speed operation, seeding precision are low, seed damage ratio height, for example existing outer groove wheel, indent type, horizontal circle disc type, make up disc type, finger-clipped seeding unit or the like.Though the finger-clipped seeding unit that the U.S. developed can be realized the high speed operation; The seeding precision is high; But it exists material requirements is high, machining accuracy is high, cost is high, difficulty of processing is big, maintenance difficult; And to problems such as seed profile, dimensional requirement height, and the requirement of the little plot of incompatibility China peasant household, low cost, low price.
Summary of the invention
The objective of the invention is to overcome that complex structure, the power consumption seed sizes big, that body is heavy and the mechanical type seeding unit exists that pneumatic type seeding unit in the background technology exists is strict, the seeding precision is low and problem such as seed damage, a kind of up-and-down reciprocating seeding unit is provided.
To achieve these goals, the invention provides following technical scheme:
A kind of up-and-down reciprocating seeding unit is characterized in that:
Said up-and-down reciprocating seeding unit comprises:
Driving mechanism, said driving mechanism comprise line shaft 1, be installed on the line shaft 1 cam 2 and with cam 2 contacted bases 7;
Feed mechanism, said feed mechanism comprise discharging tube 4, seeding bar 5, spring 6, fill kind of device 11, feed outlet 13, tip chute 14; Wherein, the lower end of seeding bar 5 is welded on the base 7, and the upper end of seeding bar 5 is arranged with spring 6 and fills kind of device 11;
Plant case, said kind of case comprises conical hollow case 8, following conical hollow case 9; Wherein,
Feed outlet 13 is positioned at conical hollow case 8 upper ends, and discharging tube 4 is positioned at the side-lower of feed outlet 13, and is connected with feed outlet 13 through tip chute 14;
Said seeding bar 5 is positioned at feed outlet 13 belows, and the diameter of seeding bar 5 is littler than feed outlet 13 apertures, and the sheathed external diameter that fills kind of device 11 is bigger than the aperture of feed outlet 13 on it.
Compared with prior art, beneficial effect of the present invention is: 1) fill kind of a device and fill kind rapidly fully, seeding need not planted brush, and seedling-damaging rate is low; 2) fill kind of a device through changing size, realize that the amount of broadcasting is adjustable, thereby realize the seeding of smart amount; 3) simple in structure, easy to use, dependable performance.Therefore the present invention is used for corn drill, helps realizing precision drilling, reduces amount of seed metering, promotes the low-carbon (LC) agricultural development.

1 is line shaft, and 2 is cam, and 3 is support, and 4 is discharging tube, and 5 for the seeding bar, and 6 be spring, and 7 be base, and 8 be last conical hollow case, and 9 are conical hollow case down, and 10 plant mouth for adorning, and 11 for filling kind of a device, and 12 is seed-filling hole, and 13 is feed outlet, and 14 is tip chute.
Embodiment
Below in conjunction with accompanying drawing the concrete structure and the course of work of the embodiment of the invention are described:
Like Fig. 1-shown in Figure 6, the up-and-down reciprocating seeding unit totally is installed on the sower frame through support 3, comprises the driving mechanism of mainly being made up of line shaft 1, cam 2, base 7; Main by discharging tube 4, seeding bar 5, spring 6, fill the feed mechanism that kind of device 11, feed outlet 13, tip chute 14 etc. are formed; Mainly by last conical hollow case 8, three in kind case forming such as conical hollow case 9 is partly formed down.
Fill the upper end that kind of device 11, spring 6 are enclosed within seeding bar 5 from top to bottom successively, and the lower end of seeding bar 5 is welded on the base 7, the power of line shaft 1 is provided by the sower land wheel, and it drives cam 2 and rotates, and then driving base 7 pumps.Seeding bar 5 upper surfaces inclinations (inclination angle is 45-55 °); Its diameter is than the smaller 2-3mm in aperture of the feed outlet 13 of last conical hollow case 8; Guaranteeing that seeding bar 5 can move by easy on and off feed outlet 13 in, and fill about the aperture 5mm of external diameter greater than the feed outlet 13 of last conical hollow case 8 of kind of device 11, when the upper surface of filling kind of device 11 is moved upwards up to when flushing with feed outlet 13 lower surfaces; Position-limiting action will be played to filling kind of device 11 in feed outlet 13 lower surfaces; Restriction is filled kind of device 11 and is moved on continuing, and that seeding bar 5 continues under the promotion of cam 2 is up, and spring 6 is compressed at this moment.Discharging tube 4 port are lower than feed outlet 13, are positioned at about feed outlet 13 side 50mm to locate, and connect through tip chute 14 between the two, guarantee that the seed that seeding bar 5 is released along feed outlet 13 gets into discharging tube 4 smoothly, accomplishes seeding.
During operation, the sower land wheel rotates through chain drive line shaft 1, thereby driving cam 2 rotations drive seeding bar 5 in the time of cam 2 rotations and pump.When cam 2 was positioned near angle of repose, seeding bar 5 was positioned at least significant end, planted seed in the case this moment and under action of gravity, slided into and fill kind of device 11 and get into seed-filling holes 12, accomplished and filled kind.Rotation along with cam 2; Kind of device 11 is filled in 5 drives of seeding bar and spring 6 moves upward together; After filling kind of device 11 upper surfaces and feed outlet 13 lower surfaces flush; Feed outlet 13 fills kind of device 11 with restriction and moves on continuing, and the seeding bar 5 of this moment will promote the seed continuation and on feed outlet 13, move, and spring 6 is compressed.When cam 2 forwarded far angle of repose to, seeding bar 5 peaked.Seeding bar 5 utilizes the inclined-plane of upper end that seed is discharged from feed outlet 13, and seed gets into discharging tube 4 along tip chute 14, accomplishes seeding.When cam 2 continued rotation, seeding bar 5 was descending under the effect of spring 6 and self gravitation, filled kind, the seeding process next time.The present invention is applicable to row-crop drills such as corn, soybean.
It should be noted last that; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the spirit and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
