Abstract

The utility model relates to a tractor-drawn reversible plough comprising a front groove plate and a back groove plate which are pressed through a thin steel plate, a left arm and a right arm, a depth control device, a regulated screw rod, a plough beam, a trenching device and a plough pan. The front groove plate and the back groove plate of the tractor-drawn reversible plough are welded through three blocks of thick steel plates which contain an upper connecting plate, a lower connecting plate and a back shield plate, and the hole spacing between a pinhole connected to the front groove plate and a main pinhole is the more closer, and then the pitch between the pin hole connected under the front groove plate and the main pinhole is the more larger; a slope angle is formed when the upper and lower connecting plate of the front and the back groove plate are welded. The depth control device of the tractor-drawn reversible plough changes the connection of square nut with ball bearing form into the cylindrical form with a connecting bar of the regulating nut which is directly connected with a supporting frame. If the thickness of the front and the back groove plate are enlarged, the weight of complete machine is improved, and the operation is more stabilized; if the angle between the pinhole connected with the front groove plate and the towed pinhole is adjusted, the operation is more convenient, and furthermore the problem that the depth control device which is loosening and deciduous easily is resolved.

Description

A kind of novel power traction pivot plow

Technical field:

The utility model relates to agricultural machinery technological field, a kind of novel power traction pivot plow.

Background technology:

Along with the continuous development of agricultural economy, the kind of agricultural machinery product is constantly enlarging, and the peasant is also constantly looking for novelty to the requirement of agricultural machinery, and is especially matching used to farm tractor, such as the power traction pivot plow, requires it to use power to increase; If run into when meeting barrier, the power traction pivot plow can strengthen because of tractive force in the use of plowing, and the distortion, distortion, the coupling part that are directed at each parts are badly damaged, causes cultivated partially, tiltedly cultivated; Phenomenons such as the dark plough of one plough is shallow; Also can cause the shortening in service life of tractor complete machine, influence peasant's use, vermachen is farming season by mistake; Cause damage for original poor peasant.

Existing 1LF-130 power traction pivot plow, because its complete machine is in light weight, the tractor front and back are uneven during the arable land, run into to occur ploughing the phenomenon that the body levitating comes when adding large traction; To connect pin-and-hole parallel with draw pin openings because the connection pin-and-hole of its preceding frid is consistent with draw pin openings, and the tractor handrail levers up too highly during the arable land, operates very inconvenience; Its front and back frid is sheet metal and is stamped to form,, yielding so its intensity is low, the pin-and-hole on the steel plate is also easy to wear, can cause the cultivated partially, tiltedly cultivated of plough after the pin-and-hole mill is big, shortens its service life; Nut on the deep ploughing adjuster of plough is loose or dislocation very easily, influences peasant's use.

Summary of the invention:

In order to overcome as above institute's problem, the purpose of this utility model provides a kind of novel power traction pivot plow, make it with than the supporting use of the farm tractor of high-power, thoroughly changed hand tractor with the ploughing partially, tiltedly plough of power traction pivot plow, not easy to operate and service life weak point problems.

For achieving the above object, the utility model adopts following technical scheme:

Novel power traction pivot plow, by the forward and backward frid that sheet metal is stamped to form, left and right arm, depth control device is regulated screw mandrel, beam, plough, the plough end, formed; Before it is described frid by upper and lower connecting plate and three blocks of steel plates of backboard through being welded, and the pitch-row that connects pin-and-hole and kingpin bore that goes up of its preceding frid furthers, before the pitch-row of following connection pin-and-hole on the frid and kingpin bore to widen its drop end also be through being welded by upper and lower connecting plate and three blocks of steel plates of backboard, the upper and lower connecting plate of forward and backward frid forms the angle of inclination when welding, thereby can adjust the whereabouts angle of plough handrail, and increased the thickness of forward and backward frid, increased the weight of complete machine.

The depth control device of novel power traction pivot plow connects square nut band ball-type, makes into directly to be connected with bracing frame for column type connecting rod adjusting nut.

Owing to adopted technical scheme as mentioned above, the utlity model has following superiority:

The utility model has adopted and has strengthened thickness preceding, frid, has improved the weight of complete machine, operates more stable; Adjust the angle that preceding frid connects pin-and-hole and draw pin openings, made more convenient operation; The grafting of deep ploughing adjuster changes the column type adjusting nut into and directly is connected with bracing frame, has solved the problem of easy loose or dislocation.

The drawing explanation:

Fig. 1 is the complete machine structure schematic diagram of novel power traction pivot plow:

Fig. 2 is the forward and backward frid structural representation of novel power traction pivot plow:

As shown in Fig. 1,2: frid before the 1-, 2-bearing pin, 3, the 4-left and right arms, the 5-drop end, 6-column type nut, the 7-depth control device is regulated screw mandrel, the 8-beam, the 9-plough, 10-ploughs central shaft, 11-ploughs the end, frid backboard before the 12-support, 13-, 14-upper junction plate pin-and-hole, frid is connected pin-and-hole with the tractor-drawn frame before the 15-, frid lower connecting plate pin-and-hole before the 16-.

Embodiment:

As shown in Fig. 1,2: in order to solve existing tractor power traction pivot plow, its complete machine is in light weight, and is uneven before and after the tractor during arable land; The tractor handrail levers up too highly during the arable land, and operation is very inconvenient; Frid is sheet metal and is stamped to form before and after it, and its intensity is low, and is yielding, and the pin-and-hole on the steel plate is also easy to wear, can cause the ploughing partially of plough, oblique problem such as cultivated after the pin-and-hole mill is big.Improved power traction pivot plow with forward and backward frid (1), (5) each with three blocks of steel plates through being welded, and the pitch-row that connects pin-and-hole (14) and kingpin bore (15) that goes up of its preceding frid furthers, and the following connection pin-and-hole (16) of preceding frid widens with the pitch-row of kingpin bore (15); Upper and lower connecting plate forms the angle of inclination when welding, thereby can adjust the whereabouts angle of plough handrail.Some increasing of each parts in the complete machine, thicken, widen, the overstriking of central shaft diameter, thereby increased complete machine weight, promoted its stability.The connection of the depth control device of power traction pivot plow makes into directly to be connected with bracing frame for column type connecting rod adjusting nut.
