V-type important city depressor
Technical field
The utility model discloses a kind of agricultural machinery, a kind of specifically V-type important city depressor.
Background technology
Packer is the specific purpose tool that is used for farmland suppression soil and leveling soil, as everyone knows, the main effect of packer is to compress soil, seed and soil are combined closely, prevent the ventilative evaporation of water in soil, help to prevent that soil water evaporation scatters and disappears, promote seed sprouting and reduce the fertilizer efficiency loss, the soil block of crushing is simultaneously leveled land, and removes behind the rain to harden in the face of land etc.Therefore packer is the indispensable farm machinery in the whole ground of agricultural.
The kind of existing packer is a lot; comprising traditional wooden packer, pressure roller packer; although above-mentioned packer brings a lot of convenience to agricultural production aspect a lot; but exist certain shortcoming and defect; be in particular in: 1. wooden packer consumes a large amount of timber in use, is unfavorable for the protection of the forest resources, and wooden in addition packer is in light weight; the suppression effect bad, can't with the supporting use of advanced person's agricultural machinery.2. the shortcoming of pressure roller packer is to run into the hillside fields to be easy to sideslip, causes for the pressure on each ridge inconsistently, can not reach the purpose of compacting, pressing, hack.
Summary of the invention
The purpose of this utility model is that a kind of simple and reasonable, real, not sideslip, the effective V-type important city depressor of suppression of pressing will be provided.
The purpose of this utility model is to realize like this, this packer comprises longeron, cant beam, front-axle beam, support arm, the back rest, baffle plate, axle, V-type pack roller, described longeron is connected with front-axle beam is vertical, two cant beam both sides that are connected longeron and front-axle beam triangular in shape, two support arms of perpendicular connection on front-axle beam, the other end of support arm is connected with the back rest, is connected with baffle plate and axle between two support arms, and the V-type pack roller is arranged on the axle.
Described longeron, cant beam, front-axle beam, support arm and the back rest fit together the frame main body that constitutes packer, the V-type pack roller by two independently the roll body assembling constitute.
Described cant beam can prolong with the back rest and interconnection is in the same place, and its interconnection end can articulate two packers, is formed with the compound packer that many group packers constitute.
The utility model is owing to adopt said structure, make that the weight of himself is more reasonable, having can compacting soil, prevent the ventilative evaporation of water in soil, help to prevent that soil water evaporation scatters and disappears, promotes seed sprouting, reduces the fertilizer efficiency advantages such as soil block of losing, level land, crush.

Embodiment
Shown in accompanying drawing 1,2: this packer comprises longeron 1, cant beam 2, front-axle beam 3, support arm 4, the back rest 5, baffle plate 6, axle 7, V-type pack roller 8, described longeron 1 and 3 vertical connections of front-axle beam, two cant beam 2 both sides that are connected longeron 1 and front-axle beam 3 triangular in shape, two support arms 4 of perpendicular connection on front-axle beam 3, the other end of support arm 4 is connected with the back rest 5, be connected with baffle plate 6 and axle 7 between two support arms 4, V-type pack roller 8 is arranged on the axle 7.
Described longeron 1, cant beam 2, front-axle beam 3, support arm 4 and the back rest 5 fit together the frame main body that constitutes packer, V-type pack roller 8 by two independently the roll body assembling constitute.
Shown in accompanying drawing 3: described cant beam 2 can prolong with the back rest 5 and interconnection is in the same place, and its interconnection end 9 can articulate two packers, is formed with the compound packer that many group packers constitute.
