Abstract
The utility model relates to a small two-hole seed-fertilizer synchronous sowing machine. The utility model is characterized in that the number of the holes and pits of a fertilizer discharging wheel is equal to the number of the holes and pits of a seed discharging wheel, the number of teeth of a driving wheel is equal to the number of teeth of a driven wheel, the fertilizer is deeply placed at the optimum position under the soil layer of the seeds, the holes of the seeds and the holes of the fertilizer are kept on the same straight-line from up to down, the efficacy of the fertilizer is utilized fully, the fertilizer is prevented from being wasted, the investment of the agricultural production is reduced, the producing demands of the seedlings are met, the fertilizer and the seeds are prevented from contacting with each other, and the seeds can not be overnourished.
Description
The utility model relates to the agricultural machinery processing technique field, is a kind of two caves sower that seed and fertilizer is applied synchronously upper and lower same linear position.
Before the present utility model, the sower that uses is commonly used two kinds, a kind of is the ZBF-1 type animal power sowing fertilizer applicator of Liaoning Agricultural Mechanization Institute's development, this machine is a single shaft two-wheel side fertilising side sowing double-row drilling machine, it is that seed and fertilizer all can not be in ridge central authorities on seed and fertilizer flat planting two straight lines at grade.Another kind is the 702A type sower that Kangping, Liaoning Province sower factory produces, as shown in Figure 3, the groundwork principle is to hold fertilizer 12 in the fertile case 11, rotates by defertilizing wheel 13, the fertile cave hole 20 of fertilizer 12 from defertilizing wheel 13 fallen, apply in the soil layer from colter 14 middle fertilizer delivering pipes 15 again; Plant in the case 16 and hold seed 17, seed wheel 18 is provided with kind of a hole, cave 19, rotates by seed wheel 18, and the seed 17 in kind of the hole, cave 19 is broadcast in the underground layer.Its major defect is: this sower is because defertilizing wheel 13 is unequal with hole, the cave number of seed wheel 18, and the hole, cave of defertilizing wheel 13 is many, forms fertilising and is strip, sowing is cave-shaped, causes with fertile more, and has many fertilizer far away from seed, can not be very fast by plant absorbing, cause the significant wastage of base fertilizer.
The purpose of this utility model is that the seed wheel of sower and defertilizing wheel design cavitation hole number are equated that the driving wheel and the follower number of teeth are equal fully, reaches kind of cave and fertile cave two caves of upper and lower same linear position synchronously.
The purpose of this utility model realizes by the following technical solutions:
A kind of small-sized seed manure synchronous double-point seeder, comprise land wheel, seed wheel, defertilizing wheel, driving wheel and follower, wherein land wheel is fixed on the same axle with driving wheel and is connected, driving wheel is fixed on the same axle with defertilizing wheel and is connected, follower is fixed on the same axle with seed wheel and is connected, defertilizing wheel equates that with hole, the cave number of seed wheel driving wheel equates with the number of teeth of follower, reaches kind of cave and the fertile cave two caves of upper and lower same linear position synchronously.
The idle wheel synchronized links together synchronous driving gear and synchronous driven gear.
The chain synchronized is with synchronous drive sprocket and linked together by movable sprocket synchronously.
Major advantage of the present utility model is:
1. owing to realize the purpose that the two bunch plantings of upper and lower same straight line synchronously of seed and fertilizer are executed, save base fertilizer in a large number, reduced agriculture input cost;
2. apply the only position below the seed soil layer because design the time guarantees fertilizer, the centre has soil layer to separate, and reduces fertilizer loss and avoid fertilizer contact with seed to produce the end that covers that burning plants.
3. because sowing keeps spacing in the rows, line-spacing is uniform, helps field management such as machinery topdresses, weeding by machine.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 a is the schematic diagram that the utility model passes through the idle wheel synchronized.
Fig. 1 b is the end view of the utility model idle wheel synchronized.
Fig. 2 a is the schematic diagram that the utility model passes through the chain synchronized.
Fig. 2 b is the end view of the utility model chain synchronized.
Fig. 3 is sower 702A type structure chart commonly used.
Consult Fig. 1 a and 1b, land wheel 1 drives sower and defertilizing wheel 2 advances, and defertilizing wheel 2 is provided with hole, quantitative fertilizer cave 7, and defertilizing wheel 2 is connected with synchronous driving gear 3; Seed wheel 6 is provided with hole, quantitative seed cave 8, and the hole, cave 7 of cave of seed wheel 6 anti-several 8 and defertilizing wheel 2 equates, all is hole, a cave.Synchronous driving gear 3 and equal by the number of teeth of ground moving gear 5 synchronously, seed wheel 6 is connected with passive and synchronous gear 5; Idle wheel synchronized 4 is connected synchronous driving gear 3 with synchronous follower gear 5, drive defertilizing wheel 2 and seed wheel 6 and rotate synchronously, realizes kind of cave and the fertile cave purpose in upper and lower same linear position pair caves synchronously.
Consult Fig. 2 a and Fig. 2 b, present embodiment and the difference of Fig. 1 a and Fig. 1 b are that the cave of defertilizing wheel 2 and seed wheel 6 cheats several 7 and 8 and equate, all are holes, 2 caves.Chain synchronized 10 with synchronous drive sprocket 9 be connected by movable sprocket 11 synchronously, drive defertilizing wheel 2 and seed wheel 6 and rotate synchronously, realize kind of cave and the fertile cave purpose in upper and lower same linear position pair caves synchronously.
The spacing in the rows adjustment solves with defertilizing wheel 2 and hole, seed wheel 6 caves number.
Distance is adjusted between fertile cave and the kind cave, because defertilizing wheel 2 is connected with synchronous driving gear 3, so fertilizer applies soil layer earlier, fertile cave is below soil layer, plant the cave on fertile cave, fertile cave and the distance of planting between the cave are adjusted by gear synchronized 4 or 10 realizations of chain synchronized, and for example, driving gear 3 is motionless synchronously, synchronous driven gear 5 is rotated a tooth pitch, or driven gear 5 is motionless synchronously, and synchronous driving gear 3 is rotated a tooth pitch, and then fertile cave and the distance of planting between the cave change.Describe Changing Pattern below for example in detail.
| Several are cheated in the | 2 | 3 | 4 | 5 | 6 |
| Several are cheated in the | 2 | 3 | 4 | 5 | 6 |
| Spacing in the rows mm | 858 | 570 | 428 | 342 | 285 |
