(54) MACHINE FOR QUICKLY SA} KENTSEV

I

The invention relates to agricultural machinery, in particular to machines for digging planting material of garden and forest crops in nurseries.

There are known machines for digging out seedlings, including a frame, an undermining bracket mounted on it, a selective working body in the form of two adjacent conveyor belts, a separating conveyor and a drive mechanism of П Г Г21.

The disadvantage of the famous cars owner -. low quality of digging of seedlings due to injury of their trunks and roots.

The purpose of the invention is to improve the quality of digging seedlings by reducing their injury.

This goal is achieved by the fact that in a machine for digging up seedlings, which includes a frame, a digging bracket mounted on it, a selective working body in the form of two adjoining arms

To the other belt conveyors, the separating conveyor and the drive mechanism, the undermining bracket is mounted on the frame by means of a vertical hinge and connected to it by a hydraulic cylinder, and the selective working body is equipped with a guide bar that is installed behind one of its conveyors while the other conveyor is made in the form of a wheel.

FIG. 1 shows schematically the proposed maschine, side view; in fig. 2 - the same, top view.

A frame is mounted on the tractor, on which the undercutting bracket 2 is mounted, a selective working body in the form of a belt conveyor 3 and the body 4 adjoining it. A bar 5 is fixed behind the conveyor along it, and its belt is provided with rubberized fingers 6.

The undermining bracket consists of two side vertical undercutting knives 7, plowshares 8, passing 3 into extension 9, the function of which is raising the stratum. Behind the undermining bracket, side rails 10 are installed, which is a continuation of the pruning knives 7. Instead of the plowshare extender, which is a smooth sheet, an active or passive type conveyor can be installed to ensure that the layer with the root system of seedlings passes through it. The front part of the undermining speed is fixed to the frame 1 by means of a vertical hinge 11, and the rear part is connected to the frame by means of a hydraulic cylinder 12 controlled from the tractor cab, ensuring its movement in the transverse direction. Separating conveyor 13 is an endless bar 14 driven and 15 leading shaft. Belt conveyor 3 is installed on the lead 16 and driven 17 pulleys with elastic dinners (for example, rubber). In the area of the pulley 17, a rubberized wheel 4 contacts the conveyor, which, together with one end of the bar 5 bent against the movement of seedlings, forms a receiving mouth for trunks coming from the driving bracket. The diameters of the driven pulley 17 and wheel 4 are calculated so that the receiving mouth, formed by 1/4 of the circumference of their rims in width, is not less than the distance of movement of the rear part of the extension 9 by the hydraulic cylinder 12 in the transverse direction. The drive to the drive shaft 15 of the separating conveyor is from the hydraulic motor 18 through the gearbox 19 The drive pulley 16 of the belt conveyor is rotated from the drive shaft 15 of the separating conveyor through a pair of bevel gears 20. The depth of digging is adjusted by the support wheel 21. The lift to the transport and lowering to the working position of the machine is carried out by a hydraulic cylinder. The machine works as follows. The tractor driver lowers the brace 2 to the working position and starts moving. The cut soil layer with seedlings rises along the extension 9 and is fed to the separator 1st conveyor 13. When the brace moves away from the rear of the plants, the tractor driver by the cylinder 12 moves the back part the extension 9, whereby the undermining bracket turns around the hinge 11. The vertical cutting knives 7 then become at an angle to the direction of movement and move the bracket in the desired direction, helping control the unit . The seedlings, passed along the extension 9, enter the separating conveyor and at this time their trunks enter the receiving mouth formed by the pulley 17, wheel 4 and the end of the bar 5. If the center of the rear part of the extension 9, and therefore the stem of the seedlings are not exactly against the center of the receiving head, they are drawn into it by the movement of a wheel or pulley of large diameter. The elastic rims of the pulleys and wheels allow for misalignment of the stems without damaging them. Having entered the separating conveyor, the seedlings are moved along it, and their trunks are kept in a vertical or slightly inclined position in the cells formed by rubberized fingers 6 and bar 5. Separating; the root system of seedlings is removed from the soil by the transporter, and they move to the left of the movement zone unit, clearing the passage for the next arrival. The use of the invention will improve the quality of planting material and improve the working conditions when performing this operation. The invention The machine for digging seedlings, including a frame, mounted on it podkapshayuyu bracket, selective working body in the form of two adjacent belt conveyors, separating conveyor and drive mechanism, making it possible to improve the quality of digging seedlings by reducing injuring them, the undermining bracket is mounted on the frame by means of a vertical hinge and connected to it by a hydraulic cylinder, and the selective working body is equipped with a guide bar, which is installed in one m of its conveyor, the other conveyor is in the form of a wheel.
