Description
【Technical field】
The present invention relates to agricultural machinery technological field, more particularly to a kind of feed mechanism for seed.
【Background technology】
At present, the species of feed mechanism for seed is varied on the market, and existing feed mechanism for seed includes grooved pulley type, nail wheel formula, key, leaf
Wheeled, centrifugal, aspirated-air type and finger-clipped etc., although the species of feed mechanism for seed is various, the general requirement for feed mechanism for seed has
One similitude, i.e.,：The amount of broadcasting will be stablized, seeding is uniform, the good, amount of broadcasting adjustable range is big, easy to adjust not to damage seed, versatility
It is reliable etc..But current feed mechanism for seed all cannot simultaneously fully meet above-mentioned requirements, for example, external recessing is although stability
It is good, but there is pulsation phenomenon, seed can be also damaged, reduce seed utilization rate；Although interior fluted-roller feed mechanism does not damage kind substantially
Son, also without pulsation phenomenon, uniformity also preferably, but complicated mechanism, stability is poor.And for example air-suction seeding unit, it
Versatility is good, not tight to seed sizes and shape need, is not required to carry out strict hierarchy to seed, it is possible to increase speed of drilling, but
It is that the discharge plate and motionless vacuum chamber of revolution coordinates, airtight to require high, mechanism is complicated, easily abrasion, and hinders kind of serious a, wind
Machine power consumption is also larger.In addition, existing feed mechanism for seed dismounting is cumbersome, it is impossible to flexibly change feed mechanism for seed and be used to adapt to different fields
Close.
【The content of the invention】
In view of the foregoing, it is necessary to provide a kind of feed mechanism for seed, the inventive structure is simply compact, make, it is easy for installation, and
And seeding is stable, uniform, application rate can be controlled, and seed damage ratio is relatively low, can be widely used in agricultural seeder practice.
To reach above-mentioned purpose, the technical solution adopted in the present invention is：A kind of feed mechanism for seed, including frame and installed in institute
State seeding box in frame, active plate, push rod groove, transfer bar mechanism, cam mechanism, spring and motor, the seeding box bottom
Offer out kind of a mouth；The active plate is slidably mounted on seeding box bottom, and goes out kind of a mouth described in covering, on the active plate
Offer sowing port；The push rod groove is arranged on the lower section of active plate；The transfer bar mechanism includes push rod and roller, described to push away
Bar is slidably mounted in push rod groove, and connects active plate by connector；Described push rod one end is extended outside push rod groove, and is led to
The roller is crossed to be connected with the cam surface rolling of cam mechanism cam；The cam mechanism connects motor；The both ends of the spring
Push rod groove and push rod are connected respectively；It is moved back and forth with the common driving push rod of the cam mechanism in push rod groove, the push rod
Drive active plate moved back and forth with respect to seeding box bottom, in the active plate reciprocating movement, it is described go out kind of mouth quilt
Active plate is laminating or is connected with sowing port.
Further, a kind of feed mechanism for seed also includes discharging tube, and the discharging tube is connected on the bottom of active plate, and
The discharging tube is connected with sowing port；Or the discharging tube be arranged on frame on, and the discharging tube by sowing port with
Go out kind of a mouth connection.
Further, the discharging tube and active plate are to be detachably connected or the discharging tube and frame are detachable
Connection.
Further, one end or discharging tube that the discharging tube is connected with active plate are near one end of active plate
Inclined funnel-shaped structure, the other end is in elongated tubular construction.
Further, a kind of feed mechanism for seed also includes transmission mechanism, and the cam mechanism is exported by transmission mechanism with motor
End connection, the transmission mechanism is one kind of chain-drive mechanism and tape handler.
Further, a kind of feed mechanism for seed also includes speed regulator, the speed regulator and motor connection.
Further, the seeding box is in funnel type structure, and seed inlet is offered thereon, and the seed inlet is opened in seeding
The top of case.
Further, it is described go out kind of mouth size of the size more than sowing port, the size of the sowing port is big
The small size than seed is big 1-2 millimeters.
Further, it is to be detachably connected between the connector and active plate.
Further, the rectangular supporting structure of the frame, which is provided with seeding box bracket, push rod groove support and motor branch
Frame.
The invention has the advantages that：
1st, the feed mechanism for seed designed by the present invention is to provide power by motor, in cam and spring after driving cam running
Effect is lower to be driven push rod to be reciprocatingly slided in push rod groove and realizes the movement of active plate, and causes that active plate is formed back and forth
It is mobile, wherein, in the moving process of active plate, sowing port occurs connecting with kind of mouth is gone out, i.e., cam often rotates a circle, and goes out kind of a mouth
Connected with sowing port once, seed is discharged by discharging tube when its is interconnected.In addition, described discharging tube one end make it is inclined
Infundibulate, the other end makes elongated tubular product, i.e. discharging tube and makes inclined funnel shaped one end and is provided with inclination angle, can conveniently kind
It is sub that excessively mitigation seed is damaged, and is also prevented from card type, furthermore, vibration during using present invention walking, it is also possible to further drop
The probability of low-calorie kind.This seeding mode is small to the pressure that seed is produced, and seed discharge process relies on free-falling, will not be to its shape
Into extruding, such that it is able to reduce the damage ratio of seed, compared with traditional feed mechanism for seed, seeding of the present invention is uniform, seed damage ratio
Low, versatility is good, and cost is relatively low.
2nd, the motor that the present invention is added mainly provides power to cam mechanism, and cam mechanism is caused using the rotation of motor
Running, finally causes that active plate is moved, and realizes the interval seeding of seed.
3rd, the speed regulator that the present invention is added is used for the frequency of regulation motor, such that it is able to adjust the cycle of seeding, and then
Control seeding spacing so that seeding is uniform, therefore, the present invention can change cam speed by changing electric machine frequency, i.e.,
The working condition of feed mechanism for seed can flexibly be changed.
4th, the active plate and connector designed by the present invention are directly to be detachably connected, you can with easily by active plate
Take out, the size further according to seed selects suitable sowing port, active plate is changed, so the present invention can change
Become the diameter of sowing port, such that it is able to be used for the seeding of variety classes seed；Similarly, discharging tube of the invention and active plate it
Between or discharging tube and frame between also to be detachably connected, can also accordingly change discharging tube by changing active plate,
Realize the smooth discharge of seed.
5th, overall structure of the present invention is simple, and easy to operate, practicality is good, can accurately control sowing spacing, seeding quantity,
Can reach do not replay, broadcast leakage decreases seed and obtains damage ratio to improve the utilization rate of seed, so as to improve agricultural
The efficiency of Mechanization sowing operation so that agricultural mechanized processes are rapidly progressed.
