The controlling device is composed of a shaft tube, two road wheels, a bearing rod, a fluted disc, a pressure spring, a lock plunger and a handle, wherein, the shaft tube is transversely vertical to an upright beam of a plow share and is fixed with the upright beam of the plow share, the center of the shaft tube penetrates with a shaft lever, one end of which is fixed with a supporting arm, the lower end of the supporting arm is transversely pivoted with one road wheel, the other end of the shaft lever is fixed with the bearing rod, the lower end of the bearing rod is transversely pivoted with the road wheel, the length of the bearing rod between the shaft lever and the axes of the road wheel equals to the length of the supporting arm, the fluted disc is positioned at the same side with the bearing rod and is fixed with the shaft tube together, the fluted disc is positioned between the bearing rod and the end face of the shaft tube, the center of the fluted disc is concentric with the shaft lever, the lock plunger is movably arranged on the bearing rod at the upper part of the fluted disc along the direction of the bearing rod, the lower end of the lock plunger is blocked between two teeth of the fluted disc by the pressing of the pressure spring, and the road wheels can lift or fall through adjusting relative angle between the bearing rod and the fluted disc.

Description

Sower is adjusting device adjustable and that rise and fall with landform with sowing depth

Technical field

The utility model relate to a kind of sower with sowing depth adjusting device adjustable and that rise and fall with landform.

Background technology

At present, sower is extensive use of in the rural area, the use of sower has improved the efficient of sowing, and still, existing sower generally all is by tractor-drawn work, though the ploughshare ditch dug with a plow degree of depth of existing sower can be adjusted, but can not adjust at any time according to change of topography, when running into Qiu Bao or lowland, the degree of depth of its ditch dug with a plow increases or reduces, influence seeding operation, also influence emergence rate.

Summary of the invention

The purpose of this utility model be for the ploughshare that solves above-mentioned sower whenever and wherever possible the form height degree variation and keep the problem of the same ditch dug with a plow degree of depth, provide a kind of sower that overcomes above-mentioned shortcoming with sowing depth adjusting device adjustable and that rise and fall with landform, this adjusting device can rise and fall ploughshare with the fluctuating of landform, thereby the ditch dug with a plow degree of depth that makes ploughshare keeps same, and the ditch dug with a plow degree of depth can also be regulated.

The utility model is by central siphon, two road wheels, pole, fluted disc, compression spring, locking bolt, handle is formed, central siphon laterally is fixed together perpendicular to the suitable beam of ploughshare and with the suitable beam of ploughshare, the center of central siphon is coated with an axostylus axostyle, one end of this axostylus axostyle is fixed with support arm, the lower end of this support arm laterally articulates a road wheel, the other end of this axostylus axostyle and strut fixation are together, the lower end of pole laterally is articulated with road wheel, strut lengths between axostylus axostyle and the road wheel axle center equals the length of support arm, fluted disc and pole homonymy, fluted disc and central siphon are fixed together, fluted disc is between the end face of pole and central siphon, the center of circle of fluted disc is concentric with axostylus axostyle, the pole on fluted disc top is gone up along the pole direction and is movably set with locking bolt, the lower end of this locking bolt can be fastened between the bidentate of fluted disc, lock bolt sleeve is provided with compression spring, this compression spring compacting locking bolt lower end is between the bidentate of fluted disc, the upper end of locking bolt is provided with handle, borrow mentioning of this handle, locking bolt breaks away from the blocking to fluted disc, can regulate the relative angle between pole and the fluted disc, and then road wheel be risen or reduction.

Operation principle of the present utility model and beneficial effect are: the ploughshare device is articulated on the draw beam of sower, the suitable beam of central siphon of the present utility model and ploughshare device is fixed together, when pole when fluted disc rotates and lock, the road wheel that the pole lower end articulates upwards rises, at this moment, the ploughshare device that is fixed together with fluted disc then descends, and the ditch dug with a plow degree of depth of ploughshare device strengthens; Otherwise, when pole is upwards rotated and during locking along fluted disc, the road wheel that the pole lower end articulates descends downwards, at this moment, the ploughshare device that is fixed together with fluted disc upwards rises under the support of road wheel, the ditch dug with a plow degree of depth of ploughshare device diminishes, and then can regulate the ditch dug with a plow degree of depth, i.e. sowing depth as required arbitrarily; Moreover road wheel can rise and fall with the fluctuating of landform, and then drives the ploughshare device and rise and fall with the fluctuating of landform, has guaranteed that the ditch dug with a plow degree of depth changes with change of topography, and the ditch dug with a plow degree of depth is consistent according to the degree of depth of setting, and has after planting guaranteed emergence rate.
