Description

a planter

Technical field:

The utility model relates to a seeder, which belongs to the field of agricultural machinery.

Background technique:

Existing seeders are divided into large-scale seeders and small seeders in terms of models, and are divided into dry field seeders and paddy field seeders in terms of performance. The large seeder is pulled by a tractor, and requires a large area of farmland and flat terrain during work, which is not suitable for some farmland with a small area. Small seeders are mostly small machines designed and manufactured by farmers themselves. Their design is simple and their functions are single, which often meet the sowing requirements of paddy fields, but cannot meet the sowing requirements of dry fields; The plant spacing is a fixed value, which cannot meet the requirements of different crop seeds for row spacing and plant spacing. Moreover, the soil covering effect is poor after sowing. After sowing, it is necessary to manually remove or fill the seedlings, resulting in low crop yields and heavy field management work in the later period.

Invention content:

The purpose of the utility model is to provide an adjustable seed sowing distance, which can meet the requirements of different crop seeds for row spacing and plant spacing, and dry fields, paddy fields, and large and small fields can be used for sowing, and has a simple structure and high working efficiency. planter.

The utility model realizes above-mentioned purpose through following technical scheme:

A planter, which consists of a frame, a seed sowing box, a walking wheel, a covering wheel, a large transmission sprocket, a small transmission sprocket, a ditch opener, a drive chain, a main drive shaft, a ditch opener installation rod, and a seed box drive Shaft and cover wheel installation shaft, characterized in that: the frame is sequentially equipped with cover wheel installation shaft, seed box transmission shaft, opener installation rod and main drive shaft from left to right; the cover wheel installation shaft passes through the limit The covering wheel is fixed on the cover, the seed sowing box is fixed on the transmission shaft of the seed box through the limit sleeve, the opener is fixed on the installation rod of the opener by bolts, and the two ends of the main transmission shaft are equipped with walking wheels; the main transmission shaft and A transmission small sprocket and a transmission large sprocket are respectively housed on the seed box transmission shaft, and are connected by a transmission chain.

The seed sowing box is equidistantly formed with sowing holes, and the sowing holes are equipped with regulating pieces.

The openers, seed sowing boxes and covering wheels are arranged in a straight line on the frame.

Described frame is shaped on traction ring by one side of road wheel.

The ditch opener and the cover wheel can be replaced with a paddy field ditch opener and a paddy field cover plate.

Compared with the prior art, the utility model has the beneficial effect that: the seed sowing box, ditch opener and cover wheel of the planter are all movably installed on the drive shaft of the seed box, the ditch opener installation rod and the cover wheel installation shaft through bolts. It can move the seed box, ditch opener and covering wheel left and right to adjust the size of the crop row spacing, and can adjust the size of the crop plant spacing by replacing the transmission small sprocket, which solves the problem that the existing seeder sows the seeds. The row spacing and the plant spacing are fixed value, which cannot meet the requirements of different crop seeds for row spacing and plant spacing. And by replacing the ditch opener and covering wheel, both dry and paddy fields can be sown, and one machine can be used for multiple purposes. And it has the characteristics of simple structure, high working efficiency, and convenient use. It can be driven by a tractor, or manually pulled or pulled by cattle. It is suitable for farmlands of various sizes.

Detailed ways:

The planter consists of a frame 1, a seed sowing box 2, a traveling wheel 3, a cover wheel 4, a large transmission sprocket 5, a small transmission sprocket 6, a ditch opener 7, a drive chain 8, a main drive shaft 9, and a ditch opener Mounting bar 10, seed box drive shaft 11, covering wheel mounting shaft 12 forms (referring to accompanying drawing 1). The rectangular frame 1 that adopts square steel to make is successively equipped with covering wheel installation shaft 12, seed box transmission shaft 11, ditch opener installation bar 10 and main transmission shaft 9 from left to right.

Covering wheel mounting shaft 12 is fixed with covering wheel 4 by limit sleeve 17, and the effect of covering wheel 4 is to play a supporting role to frame 1, and the 2nd is to cover (buried) crop seeds in the ground by its rolling to field. in the soil.

The seed box transmission shaft 11 is fixed with a seed sowing box 2 through a stopper 17, the seed sowing box 2 is a closed cylinder, and its surface is equidistantly spaced with 3 rows of sowing holes 16, and the sowing holes 16 are equipped with regulating pieces , its effect is to adjust the size of sowing hole 16, to control the seeding rate of different crop seeds. One side of sowing hole 16 is shaped on seed filling hole, and filling hole cover plate is housed on it, and is fixed by bolt.

The opener 7 is fixed on the opener installation rod 10 by bolts 15. The opener 7 is in the shape of a "claw". By adjusting the angle between the opener 7 and the ground, the depth of the open trench can be controlled to suit different Needed for sowing of crop seeds.

Ditch opener 7, seed sowing box 2 and covering wheel 4 are arranged in a straight line on frame 1, and the two ends of main transmission shaft 9 are equipped with walking wheels 3, and frame 1 is shaped on two traction wheels on one side by walking wheels 3. Ring 18. On the main transmission shaft 9 and the seed box transmission shaft 11, the transmission small sprocket 6 and the transmission large sprocket 5 are respectively housed, and the transmission small sprocket 6 and the transmission large sprocket 5 are connected by the transmission chain 8. When this planter was used in the paddy field, the ditch opener 7 and the cover wheel 4 need to be replaced with the paddy field ditch opener 13 and the paddy field cover plate 14 (see accompanying drawing 2-3).

The planter is pulled forward by the traction external force through the traction ring 18. On the one hand, the road wheel 3 drives the main drive shaft 9 to rotate, and the main drive shaft 9 drives the small drive sprocket 6 fixed on it to rotate. Drive transmission large sprocket 5 to rotate, thereby make seed box transmission shaft 11 and seed sowing box 2 rotate synchronously. On the other hand, the traction ring 18 drives the ditch opener 7 through the frame 1 to drive the field out of the ditch, and the seed sowing box 2 is rotating, and the seeds are evenly sown in the ditch opened by the ditch opener 7 through the sowing hole 16. , and the crop seeds are covered (buried) in the soil through the rolling of the covering wheel 4 to the trench soil, and the sowing work is completed.

When the utility model was working in the paddy field, the above-mentioned ditch opener 7 and the covering wheel 4 could not be applicable to the paddy field operation because the situation of the paddy field was completely different from that of the dry field. Now, it is only necessary to replace the ditch opener 7 and the cover wheel 4 of the planter with the paddy field ditch opener 13 and the paddy field cover plate 14. The paddy field cover plate 14 is a slightly arc-shaped plate, and its effect is the same as that of the cover wheel 4. The one is to support the frame 1, and the second is to cover (bury) the crop seeds in the soil, and The resistance is much smaller than the covering wheel 4, no matter whether the planter is pulled by machinery or manually, it is labor-saving and labor-saving. The paddy field ditch opener 13 is a diamond-shaped plate, and the width of the ditch is greater than that of the ditch opener 7. The purpose is to prevent the ditch opened by the crop seeds from being automatically backfilled before falling into the ditch. .

The seed sowing box 2 of the utility model, the ditch opener 7 and the cover wheel 4 are all set on the seed box transmission shaft 11, the ditch opener installation rod 10 and the cover wheel installation shaft 12, and the seed sow box 2 and the ditch are moved left and right. Device 7 and cover wheel 4 can adjust the size of crop row spacing, change the size of transmission small sprocket 6 adjustable crop spacing, and can accomplish dry field and paddy field sowing dual-purpose. It can be driven by a tractor or manually, and has the characteristics of simple structure, high work efficiency and convenient use.
