Abstract

Disclosed is a turnover plow for high yield furrows, mainly comprising a furrowing plow share, a surface soil backfill plow share, a break shovel, a breast board, a furrow pressing roller and harrow, a depth wheel and a plow stock. The furrowing plow share and the surface soil backfill plow share are arranged vertically to each other, and are respectively positioned on both sides of the plow stock for alternatively working by mutually turning over. The turnover plow is suitable for being drawn by a small four wheel tractor with 12-25 horsepower. With advantages of compact structure, light weight, multiple functions, small traction resistance, flexible rotation, easy adjustment, non-deflective traction and favorable preservation of soil moisture, the utility model can do shuttle working to thoroughly separate raw and mellow soil so as to form a rectangular furrow.

Description

Two-way alternative plow

The utility model relates to a kind of special-purpose farm machinery of constructing the high yield ditch.

In the patent No. is that CN89220048.0, denomination of invention have been cheated a kind of high yield ditch plough for the Chinese patent intermediary of " water-storage fertilizer-accumulation soil repairment power tiller ", this plough can be built trench digging the ridge and once finish with the table earthen backfill, corresponding required drawbar horsepower is bigger, be unsuitable for the fraction horsepower tractor-drawn, simultaneously owing to plough and to overturn, so can not carry out shuttle working, the last institute ditch dug with a plow that stays is bigger, uses the restriction that is subjected to the plot gradient.

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of convertible high yield ditch plough of suitable fraction horsepower tractor-drawn is provided.

The convertible high yield ditch plough of the utility model mainly comprises ditching share, table earthen backfill ploughshare, break shovel, uprightly rolls, breast boards, ditch pressing roller and rake, plow frame and gauge wheel.Plow frame is made of hanger bracket, girder, upset three joints and handle, V-arrangement card and longitudinal tie.Ditching share and table earthen backfill ploughshare are contained in upset three joint both sides respectively, and mutual arranged perpendicular, and table earthen backfill ploughshare is the big single ploughshare structure of soil-shifting shovel, and its two plow standard is synchronous rotational structure, and table earthen backfill turnplow post is shorter than the height of ditching share plow standard.Two ploughshares can overturn mutually, alternation, and this is by three joints and the handle control of overturning.

Fig. 1 builds ridge duty for this high yield ditch plough at trench digging and faces structural representation.

Fig. 2 is the left view of Fig. 1.

Fig. 3 faces structural representation for this high yield ditch plough in table earthen backfill duty.

Fig. 4 is the right view of Fig. 3.

Fig. 5 is the colter structural representation.

Among the figure: 1, ditch pressing roller, 2, the rake, 3, the rake support, 4, small rack, 5, table earthen backfill ploughshare, 6, hanger bracket, 7, handle, 8, the V-arrangement card, 9, towing pin, 10, the upright support that rolls, 11, breast boards, 12, upright rolling, 13, ditching share, 14, chisel point, 15, gauge wheel, 16, preceding plow standard, 17, tail wheel, 18, upset three joints, 19, longitudinal tie, 20, girder, 21, the native ploughshare side plate of table, 22, plow standard, 23, colter, 24, coupling sleeve, 25,27, pin, 26, back plow standard, 28, position block, 29, locating hole.

Ditching share 13 and the upright support 10 that rolls are contained in upset three joints 18 right sides by plow standard 22, upright roll 12 and breast boards 11 be contained in upright rolling on the support 10 respectively, upright rolling is positioned at the ditching share outside.Plow standard 22 can be with ditching share 13 and uprightly roll support 10 and rotate together.Chisel point 14 is contained in plow standard 22 lower ends by pin 25, and can pin 25 be axially preceding the rotation, when upset is landed that break shovel 14 foldings are bad to prevent ditching share 13, also have a location block in pin 25 fronts, can make break shovel 14 be positioned at the upright position, can not rotate backward again.

Plow standard 16 is contained on the girder 20 by movable coupling sleeve 24 before the table earthen backfill ploughshare, and back plow standard 26 and rake support 3 together are contained in upset three joints 18 left sides, and forward and backward

plow standard

16,26 and support 3 can rotate synchronously.Ditch pressing roller 1 and rake 2 are contained on the rake support 3 by small rack 4.Colter 23 is contained in the native ploughshare side plate of table 21 back lower places by pin 27; colter 23 can pin 27 be axially preceding the rotation, loses when landing with protection colter 23, and a location block 28 is arranged in pin 27 fronts; can make colter 23 be positioned at the upright position, and can not turn round again.Colter 23 can be regulated the degree of depth by locating hole 29.

Handle 7 is fixed on upset three joints 18 middle parts, and controlled is overturn, and three joints 18 drive ditching share 13 and table earthen backfill ploughshare 5 serves as that each 90 ° (or in 100 °) rotated about axle was done with girder 20.When building ridge operation when ditching, handle 7 is pushed in the V-arrangement card 8 right side grooves, with ditching share 13 with uprightly roll support 10 and put down, will show earthen backfill ploughshare 5 simultaneously and harrow support 3 and hold up.Ditching share 13 is filled out soil in the ditch with kind and is turned over to a side and ridge, and uprightly rolls 12 and can prevent immature soil backfill on the ridge, and reduce the mouldboard resistance, and breast boards 11 can prevent that the immature soil on the opposite side ridge from entering in the ditch.Be positioned at the inboard tail wheel 17 in ditching share 13 backs and be contained on the plow standard 22, tail wheel 17 is trapezoidal, can reduce deflective traction, makes ditching share 13 working stabilities, reduces resistance.Behind the trench digging, chisel point 14 is with the further dark pine of the immature soil in the ditch.When showing the earthen backfill operation, handle 7 is pushed in the V-arrangement card 8 left side grooves, will show earthen backfill ploughshare 5 and rake support 3 puts down, simultaneously with ditching share 13 with uprightly roll support 10 and hold up.Table earthen backfill ploughshare 5 will show soil and insert in the plantation ditch that digs, and the colter 23 that is contained under the native ploughshare side plate 21 of table is cut Yi Tiaogou with the following immature soil after the table earthen backfill, reducing deflective traction, and can be next the trench digging and will reduce resistance.After showing earthen backfill, ditch pressing roller 1 will be planted the interior table of ditch soil with rake 2 thereupon and be raked pressure sternly, preserve soil moisture with hack.Gauge wheel 15 adjustable height are by regulating the tilling depth of gauge wheel 15 Height Adjustable ploughs.Hanger bracket 6 mounts in the tractor back by towing pin 9 and connection holes.Longitudinal tie 19 makes hanger bracket 6 and girder 20 form rock-steady structure, with the lifting of assurance plough and the longitudinal stability of farming.

The utility model is fit to the traction of 12-25 horsepower tractor with small four wheels.As drawbar horsepower little (as 12 horsepowers), can as required trench digging be built the ridge or table earthen backfill operation and be divided into repeatedly and carrying out.The utility model is compared with existing high yield ditch plough, compact conformation, reasonable in design, in light weight, function is many, tractive resistance is little, can carry out shuttle working, one side soil to turning over, is subjected to plot gradient restriction little, rotate flexibly, easily regulate, not deflective traction is given birth to mellow soil and is separated thoroughly, ditch shape is rectangular, the rake pressure is effective after the table earthen backfill, preserves soil moisture, and meets high yield ditch agriculture requirement fully.
