Abstract

FIELD: agricultural engineering, in particular, cultivation of soil for planting of woody plant seedlings.

SUBSTANCE: apparatus has plow beam, one or several plow bodies mounted on plow beam and composed of share and moldboard, and disk knife. Plow beam has three-dimensional frame adapted for hanging to tractor suspension, and movable beam pivotally secured on bracket for rotation around vertical axis. Beam is provided with drive made in the form of, for example, hydraulic engine with belt transmission. Plow body and disk knife are disposed at opposite ends of movable beam on brackets for progressive movement along beam under the action of centrifugal force and drive, such as hydraulic cylinders. Such construction of apparatus allows plow bodies and disk knife to move independently of basic tractor and, as a consequence, effective soil cultivation to be provided on small plots for planting of one or several plants.

EFFECT: increased efficiency and simplified construction.

Description

The invention relates to devices for tillage for planting seedlings and seedlings of woody plants and can be used in forestry, utilities and agriculture.

A device for plowing small areas, including ridges, on which one or more plow bodies consisting of a ploughshare and a blade, and a cutter knife (Agricultural and land reclamation machines / G.E. Listopad, G.K.Demidov, B.D. Zonov et al. / Under the general editorship of G.E. Listopad. - M.: Agropromizdat, 1986.- 688 s, p.26, fig. 1.13).

The disadvantage of this device is the impossibility of automatic excavation when meeting with an insurmountable obstacle.

The closest is a device for plowing small sections, including ridges, on which one or several plow bodies consisting of a ploughshare and a blade, and a circular knife are installed (Kochegarov V.G. Technology and machines for logging and reforestation / V.G. Kochegarov, L.G. Fedyaev, I.A. Lavrov. - M.: Lesn. Prom-st, 1970.- 400 p., P.306, fig. 88a).

The disadvantage of this device is the impossibility of the working movement of plow bodies and a circular knife, regardless of the base tractor, and, as a result, the low efficiency of soil treatment in small areas for planting one or more plants.

This drawback is eliminated by the fact that in the device for plowing small sections, including the ridges, on which one or several plow bodies, consisting of a ploughshare and a blade, are installed, and the circular knife, the ridger has a spatial frame mounted on the tractor hitch and a movable beam pivotally mounted on the bracket is rotatable around a vertical axis and equipped with a drive, for example, in the form of a hydraulic motor with a belt drive, and the plow body, consisting of a ploughshare and a blade, and a circular knife are mounted on the counter opolozhnyh ends of the movable beam on the brackets with the possibility of translational movement along the beam under the action of centrifugal force and the actuator, such as hydraulic cylinders.

The proposed design of a device for plowing small areas allows the working movement of plow bodies and a circular knife, regardless of the base tractor, and, as a result, efficient tillage in small areas for planting one or more plants.

We did not find such a design of a single-axle trailer with steered wheels in the patent and scientific literature.

Figure 1 shows a device for plowing small areas, a general view; figure 2 is a device for plowing small areas, side view; figure 3 is the same, top view.

The device for plowing small sections consists of a ridge 1, which includes a spatial frame 2, mounted on a hydraulic hitch of a tractor 3 and a movable beam 4, pivotally mounted on an arm 5 with the possibility of rotation around a vertical axis and equipped with a drive from a hydraulic motor 6, by means of a belt drive 7. Plow the housing 8, consisting of a ploughshare 9 and a blade 10, and a circular knife 11 are installed at opposite ends of the movable beam 4 on the brackets 12 and 13, respectively, installed with the possibility of translational scheniya movable along the beam 4 under the action of centrifugal force and drive constructed in the form of hydraulic cylinders 14 and 15, respectively.

A device for plowing small areas works as follows.

A tractor with an attached device drives up to the site to be plowed so that the middle of the movable beam 4 is above the center of the site. The brackets 12 and 13 by means of hydraulic cylinders 14 and 15 are also shifted to the middle of the movable beam 4 and are held in this position. Next, the hydraulic motor 6 is turned on, which, by means of a belt drive 7, accelerates the movable beam 4 and the working bodies installed on it (plow body 8 and disk knife 11) to the required speed. After that, the device is lowered down by means of a hydraulic suspension 3 of the tractor, while the working bodies are introduced into the soil to the required depth. Then, the hydraulic cylinders 14 and 15 are turned on, which move the plow body 8 and the disk knife 11 to the ends of the movable beam 4. In this case, the plow body 8 and the disk knife 11 move in a spiral of Archimedes, and the plow body cuts the bottom with a share 9, turns over and crumbles with a dump 10 layer soil previously cut to the side with a circular knife 11. Thus, a small area of rounded form is plowed. At the end of the operation, the hydraulic motor 6 and the hydraulic cylinders 14 and 15 turn off the working bodies under the action of resistance forces, the device rises by means of the hydraulic suspension 3 of the tractor, and the tractor moves to the next section to be processed.

The proposed design of the device for plowing small plots allows the working movement of plow bodies and a circular knife, regardless of the base tractor, and as a result, efficient tillage in small plots for planting one or more plants.
