Abstract

The utility model discloses a seeding machine, comprising crate legs (1), a shifting fork bin (2), a batcher (3), a roller (4) with grooves (41), a guide wheel, a driving wheel (6) and a driven wheel (7) connected with the driving wheel (6) through a chain (8). The driving wheel (6) and the driven wheel (7) are variable gear groups. The roller (1) is provided with a plurality of the grooves (41). The utility model varies and changes the rotation speed of the roller via a viable speed wheel, and the seeding machine is capable of changing the roller with different number of grooves, thereby achieving the limited changing of the rotation speed of the roller and being suitable for the need of space of various crop seeds. The utility model is convenient and rapid.

Description

Sower

Technical field:

The utility model relates to a kind of farm implements, particularly a kind of sower.

Background technology:

At present, the drive of regular drill, driven pulley are single gear, the drum rotation speed that driven pulley drove is even, moreover the cylinder of this sower is not replaceable and groove number that have is certain, so the crop seeds spacing of sowing with a kind of sower all equates, broadcast another kind of crops as need, and the required seed spacing of this crop is different with the former, and that must change another kind of sower, and is very inconvenient; For another example: a certain crop after planting needs film to cover, regular drill must be earlier after planting epiphragma make two bites at a cherry, it is time-consuming to require great effort, and also misses the farming season sometimes, influences the crop normal mature.

Summary of the invention:

The problem that the utility model solved provides a kind of cylinder infinitely variable speeds that makes sower, thereby makes the seed spacing of sowing adjustable, adapts to various crop seeding spacing needs.

For solving the above problem that proposes, the technical scheme that the utility model adopted is: this sower comprises that building leg, shift fork bucket, batcher, the cylinder that has groove, guide wheel, drive reach and its driven pulley that is connected by chain, and drive, driven pulley are respectively the change-speed gearing group.

As a kind of improvement project of the utility model be: the cylinder of sower has several grooves.

As the another kind of improvement project of the utility model be: roller shaft one end of sower stretches out batcher and is connected with driven pulley, and the other end also stretches out batcher, and this external part is provided with the retaining bowl

As another improvement project of the utility model be: establish shift fork in the shift fork bucket, shift fork links to each other by the gear of rotating shaft with the shift fork bucket outside, and this gear is meshed with drive.

As another improvement project of the utility model be: the building leg of this sower links to each other with film mulch-laying machine support is anterior.

As another improvement project of the utility model be: the film mulch-laying machine support that is connected with this sower is provided with pinch roller.

As another improvement project of the utility model be: the ploughshare of film mulch-laying machine is located on the support in pinch roller the place ahead.

The drive that guide wheel drove of the utility model sower is a change pulley, drive also is a change pulley by the driven pulley that chain connects, guide wheel is by behind the drive, the transmission of driven pulley speed change like this, and drum rotation speed just can change, and cylinder revolves the seed spacing of sowing and just can change like this; Roller shaft one end of the present utility model stretches out batcher and is connected with driven pulley, the other end also stretches out batcher, and this external part is provided with the retaining bowl, when needs change when sowing sub-spacing, the retaining bowl can be laid down, extract roller shaft out to driven pulley one side, displacement has the cylinder of different groove numbers, can reach also that to revolve the seed spacing of sowing different even drum rotation speed is constant like this; Sower of the present utility model changes drum rotation speed, the different cylinder of replaceable groove number again by the change pulley speed change, so just can reach the stepless change seed spacing, adapts to various crop seeds spacing needs, and is convenient, fast; The utility model is also adorned a shift fork in shift fork bucket bottom, the rotating shaft of shift fork is connected with gear, this gear is meshed with the driven pulley of below, gear rotates the drive shift fork and rotates in the shift fork bucket, shift fork just can mix the crop seed in the shift fork bucket, also is beneficial to crop seed and very successfully is transported in the interior cylinder gap of batcher; Moreover the utility model sower also can link to each other with the film mulch-laying machine, can once finish with the lid film with sowing, and is time saving and energy saving.

Fig. 2 is the left view of sower shown in Figure 1.

Fig. 3 is the film mulch-laying machine front view that the utility model sower is connected.

Fig. 4 is the vertical view of film mulch-laying machine shown in Figure 3.

Embodiment:

As shown in Figure 1 and Figure 2, the utility model sower can change guide wheel 5 one sides of regular drill into change pulley by the drive 6 that ball connects, change pulley is the different gear train of diameter, the driven pulley 7 that links to each other with cylinder 4 also is changed to the different gear train of diameter, be that chain 8 one ends are on the bigger gear of drive 6 diameters, and chain 8 other ends are just on the less gear of driven pulley 7 diameters, can regulate easily like this driven pulley 7 with the rotating speed of cylinder 4; The utility model can be done the cylinder 4 of a plurality of different groove 41 numbers, and as doing the cylinder 4 with 5 or 6 grooves 41, groove 41 also can be the pit that is arranged on the cylinder 4, can be fit to bunch planting or the program request of crop like this; Rotating shaft one end of cylinder 4 stretches out batcher 3 and is connected with driven pulley 7, the other end also stretches out batcher 3, external part is with retaining bowl 22, require the seed spacing according to crop, the retaining bowl 42 of cylinder 4 roller end can be removed, cylinder 4 rotating shafts are gone out to this layback together with driven pulley 7, take original cylinder 4, change the different cylinder 4 of groove 41 numbers; The utility model is also adorned a shift fork 21 in shift fork bucket 2 bottoms, and shift fork 21 is for rotating shaft and have and revolve wing or vertical bar, and rotating shaft one end stretches out shift fork bucket 2, and external part is connected with a gear 22, and gear 22 is meshed with the driven pulley 7 of below batcher 3 one sides.As shown in Figure 3, Figure 4, building of the present utility model leg 1 also can link to each other with film mulch-laying machine front carriage 9, promptly fix an annulus respectively at place, film mulch-laying machine support 9 anterior nearly two ends, the building leg 1 of the utility model sower is injected in the annulus, fixing then, also fix a playscript with stage directions utility model sower by another annulus equally, such two these sowers just are connected as a single entity with the film mulch-laying machine, just can reach first epiphragma after planting and once finish; Establish the wheel pressing shaft 911 that has pinch roller 91 before the film mandrel 93 of film mulch-laying machine, wheel pressing shaft 911 two ends link to each other with the support 9 of film mulch-laying machine, and pinch roller 91 is corresponding with the building ploughshare of anterior sower; The ploughshare 92 of the utility model film mulch-laying machine is located on the support 9 in pinch roller 91 the place aheads, and away from the building ploughshare of sower, and the ditch that turned over of film mulch-laying machine ploughshare 92 can not covered by the soil that the building ploughshare of sower is turned over like this.The utility model is broadcast together in order to adapt to the two ridges of crop, two the utility model sowers can be coupled together use, and is convenient and swift.
