A kind of corn simple grain divides equally precision drill, and conveying mechanism is arranged in parallel in front next two columns, under feed mechanism for seed 2
Side, each column conveying mechanism is made up of upper and lower belt wheel, upper and lower belt shaft, Timing Belt 12.The upper band wheel shaft of conveying mechanism during installation
Axis feed shaft axis corresponding with its same column is located in same perpendicular；Multiple belt wheels 11 are installed on each belt shaft 10,
With adjacent belt pulleys spacing distance on root belt shaft 10 be the width of Timing Belt 12, the belt wheel 11, Timing Belt of front next two columns conveying mechanism
12 replace plug hole arrangement.Timing Belt is inclined to be installed, with the inclination angle that the ground of the direction of machine travel is in 30 °～75 °, prostatitis Timing Belt
Inclination angle of 12 inclination angle more than or equal to rank rear Timing Belt；The lower end of Timing Belt 12 is located between plough biside plate, close proximity to ground,
Make the height of drop of seed as far as possible little, prevent the spring after seed landing, it is ensured that seed spacing.The surface of Timing Belt 12 is provided with seed
Location hole 13, the lower end in placing of seed hole 13 is set as V-type, is slipped to the V in placing of seed hole 13 in seed course of conveying in gravity
Type tip, depending on the size in placing of seed hole 13 is according to broadcast cereal seed size, the centre-to-centre spacing of placing of seed hole 13 is broadcast according to mu
The seed spacing that gauge is calculated determines.Seed retaining plate 4 is arranged on the top of Timing Belt 12, and installation parallel with the surface of Timing Belt 12 is prevented
Seed is in transportation because machine vibration drops out location hole；The width of seed retaining plate 4 is equal to the sowing fabric width of each column Timing Belt 12；For
Avoid seed retaining plate 4 from hindering Timing Belt to rotate, there is a minim gap between seed retaining plate 4 and Timing Belt 12.Plough 5 adopts core share type
Plough, is arranged in frame by U-bolt, corresponding with Timing Belt 12 to be alternately arranged in front next two columns are equidistant；Trench digging
The biside plate inner distance of device 5 can be customized as needed, the peace of the fore-and-aft direction of plough 5 slightly larger than the width of single Timing Belt 12
Holding position will ensure that the position of charging seed of correspondence Timing Belt 12 is in before the side plate back edge of plough 5, it is ensured that seed is returned in soil
Kind of a ditch is fallen into before stream, so as to ensure distribution grain of the seed on plot away from uniformity.The leading screw 14 of plough 5 and column 17
It is threaded connection, rotational lead screw 14, plough 5 can be moved up and down, so as to adjust ditching depth；Each plough 5 can be single
Solely adjust.Drive sprocket 19 is arranged in repression axle, and external sprocket wheel 18 is arranged on the one end of feed shaft 3, with drive sprocket 19
In the homonymy of frame 9；Transmission sprocket wheel 20 is separately mounted on feed shaft 3 and belt shaft 10, positioned at the opposite side of frame；Drive chain
Wheel 19 is rotated with press wheel 7, drives feed mechanism for seed 2 to rotate by Chain conveyer, and feed shaft 3 is by transmitting the chain-driving of sprocket wheel 20
Timing Belt 12 is rotated.To realize that seeder divides equally precise sowing, have one between press wheel and feed mechanism for seed, feed mechanism for seed and Timing Belt
Fixed gear ratio, gear ratio requires to determine according to sowing.
This corn simple grain divides equally precision drill by taking type hole Type Seed Metering Device as an example.The type hole of feed mechanism for seed and Timing Belt 12
The quantity in placing of seed hole 13 and interval are required to determine by sowing；It is to ensure precision metering device, under feed mechanism for seed 2 according to above-mentioned requirements
The position in the type hole of side and the placing of seed hole of the highest point of Timing Belt 12 corresponds.During operation, tractor passes through trifilar suspension
Device drives seeder work, drive sprocket 19 to drive feed mechanism for seed 2 to rotate by Chain conveyer, now plants the seed in case 1 by weight
Power falls in the type hole of feed mechanism for seed 2, and with the rotation of feed mechanism for seed 2, seeds scraper scrapes off seed unnecessary in type hole, only retains one
Seed；Seed goes to lower section under seeds protecting plate protection with feed mechanism for seed, under gravity by sowing port, accurately falls in Timing Belt
Placing of seed hole in, and be slipped to the minimum point in V-type placing of seed hole 13；With the work of seeder, Timing Belt 12 is in gear
Plant and transport downwards under the protection of plate 4 seed, plough outputs smooth kind ditch, and the seed in location hole steadily, uniformly falls on ground
On block；The subsequent earthing of coverer 6, press wheel 7 is suppressed.
If the corn mu amount of broadcasting is M, corn mass of 1000 kernel is m, even distribution of seed in plot, then seed spacing
Then transversely the centre-to-centre spacing of two adjacent location holes is equal to s on Timing Belt.
If a diameter of D of land presser, hole roller has k type hole in one week, thenN in formula --- suppression rotation 1
Circle, the number of turns of type hole rotation.The then gear ratio of land presser and hole rollerIt is synchronous if a diameter of d of Toothed belt pulley
It is l to take longitudinally adjacent location hole correspondence position distance, due to the location hole in the type hole and Timing Belt on hole roller one by one
Correspondence, thenN in formula1Feed mechanism for seed turns 1 circle, the corresponding number of turns with rotation.The then gear ratio of feed mechanism for seed and belt wheelArrange by above-mentioned size and gear ratio, it is ensured that sowing plant/line spacing is s, and seed is uniformly distributed in plot.
This utility model is capable of achieving the mechanical precise sowing of corn straight uniform, it is ensured that when seed falls on plot line-spacing and
Spacing in the rows uniformity, seed is uniformly distributed in plot, makes seed make full use of the light in monoblock soil, water, fertilizer, it is to avoid
Crop strives water and strives fertilizer in tradition sowing ridge, and in the ranks neutral gear water, fertilizer, light cannot get the phenomenon of effectively utilizes, can increase corn product
Amount.
Protection domain not limited to this of the present utility model, any those familiar with the art is in this utility model
In the technical scope of disclosure, the simple change or equivalence replacement of the technical scheme that can be become apparent to each fall within this practicality newly
In the protection domain of type.
