Description

(54) OPFAN WORKING FOR SEEDING OF SEEDLINGS

I

The invention relates to agricultural machinery, in particular to the device; for the extraction of seedlings from the soil, and intended for the mechanization of processes in horticulture and other areas.

Known working bodies for digging seedlings, containing a frame with a cutting blade mounted on it, on which a frame is hinged mounted with a toothed rotary ripper attached to it, the frame being connected to a Krivoshtypino-connecting rod mechanism 1 and 2.

The disadvantage of these working bodies is the poor removal of seedlings from the soil due to insufficiently good crumbling of the soil layer.

The aim of the invention is to improve the destruction of the soil layer.

The goal is achieved by the fact that in the working body for the VYKOPKI seedlings, containing a frame, with an undercutting blade mounted on it, on which a frame with a toothed rotary ripper attached to it is articulated, and

With the crank mechanism, the frame is provided with slats and a knife, the slats are located in two mutually intersecting and directed at an angle upward planes with the formation of a conical protrusion, the apex of which is directed toward the plowshare, and the cutting edge of the knife is inclined to the plane of the frame with the rise towards the slats along the longitudinal axis of symmetry of the frame, and the rotor ripper teeth are curved.

FIG. I depicts the working body of the day of the EXPEDITION of seedlings, side view; in fig. 2 - hinged frame, top view; in fig. 3 is a section A-A in FIG. one; in fig. 4 section bb in fig. one;

Claims (2)

The tool for digging out the sgzhents contains a frame 1 with a fixed undercutting blade 2, on which a frame 3 is mounted on hinges. In the rear part of the latter a rotary ripper 4 is mounted on bearings with curved teeth 5 fixed on it. On the frame -3 there are slats 6, fan-shaped, two planes mutually intersecting and directed at an upward angle, forming a conical protrusion 7, the top of which is directed toward the plowshare 2. On the frame 3 there is a knife 8, the edge 9 of which is located Onno to the frame plane with the rise in the direction of bars along the longitudinal axis of symmetry of the frame. A connecting rod 10 is attached to the frame 3, the upper end of which is mounted on the crank 11. The working unit for extracting seedlings works as follows. When the aggregate moves along a row of excavated culture, the stationary ploughshare 2 deepens to the required depth, digs up a layer of soil with seedlings and transmits it on frame 3, which, having oscillatory motion in a longitudinal-vertical plane, affects the layer from the bottom up, partially destroys and separates it. In the process of soil formation on frame 3, it is cut by 8 and falls on the plane of conic section 7 dissected, which contributes to (the process of its disintegration. Conical protrusion 7 actively influences the clod associated with the root part of seedlings, destroys them. At the same time, the arrangement of the strips 6 in planes angled to each other improves the dismemberment of the soil trapped on the protrusion 7 and the gaps between the strips 6 allow it to be separated. Curved teeth 5 of the rotor ripper complete the destruction of the soil: 4. Execution The rotor ripper teeth 5 curvilinear improves contact with the soil over the bar 3. 64 The use of the proposed tool allows the seedlings to be removed from the soil without considerable effort, using mechanized means (conveyors and pulling devices) Formula of the invention 1. The working body for digging seedlings, containing frame, with mounted, on it undercutting plowshare, on which the frame is pivotally mounted with a toothed rotary ripper fixed on it, with the frame connected to a Krivoshpno-connecting rod mechanism The frame is characterized in that, in order to improve the destruction of the soil layer, the frame is provided with slats and a knife, wherein the slats are arranged in two mutually intersecting and directed at an angle of the upper planes with the formation of a conical protrusion, the top of which is directed towards the plowshare, and the cutting edge the knife is located obliquely to the plane of the frame with the rise in the direction of the slats along the longitudinal axis of symmetry of the frame. 2. The body according to claim 1, that is, with the fact that the rotor ripper teeth are made curvilinear. Sources of information taken into account in the examination 1.
