Description

 A plow is proposed, the subsoilers of which can simultaneously and equally not move relative to the plow bodies when the latter are immersed in soil by raising the field wheel. To this end, the tillers of the tiller legs hang the help of the rings on the spring arms attached to the corner of the angular swivel arms, the other arms of which are connected by hinges to the other arms used to move all soil immersion arms. At the same time, the lever, wedged on the axis of the field wheel, provides H with holes for shifting the thrust in order to control the movement of the paws, relative | 1-. body plow bodies. - Modification of the submersible soil with subsoil plowers makes it possible to set the submersible tiller paws to the required depth independently of the depth of the ois of P1: curving the bottom of the plow furrow. This is due to the fact that the installation shaft /, e - KoTptjiM connected suspended tillers of tillers, connected with the field wheel by an intermediate part allowing free rotation of the installation shaft with respect to the axis of the field wheel, and than the rearranged stop, which, together with the fixed stop, the gril determines the depth of the submersible submersible.

In FIG. 1 is a side view of a plow; FIG. 2 is a top view thereof, and FIG. 3 is a side view of a modified plow.

On the crankshaft axle 1 (Figs. 1 and 2), the lever 3 is fixed by means of a cranked rod 5 connected to the eyelet 25 of the lever 6, stuck on the roller 8, and the latter is mounted on the horseshoe frame 9, which is screwed to the bearings 10 and 11 c diliu. On the roller 8, the lever 13 is fastened, with which the spring arm 14, which consists of nesplit parts, is fastened. Other spring shoulders 14 fasteners on angular pivot levers 17 rotating on stops 19 mounted on bearings 18 cr.

before the first and second plow bodies. Subsoiler 20 is suspended from spring arms 14 by means of rings in such a way that they have the ability to swing along and; across the direction of the plow. The front subsoiler 20 is connected by means of a chain 21 with a stand 12 fixed on the rear of the support wheel, as well as one of the plow bodies. On the roller 8, in addition to the lever 6, there is a lever 7 connected by means of a hinge 15 with a shoulder of one of the corner levers 17. In the same way, the other angular lever 17 is median with the help of a hinge 16 with an internal curl of the lever 6. The shoulders of the Ztlovy levers 17, to which the articulated joints 1 and 16 are connected has the same length as the lever 7. The plow is pulled and pulled out by rotating the crankshaft 1 of the wheel 2 with a simple device, as shown in the drawing. In this case, the rotation of axis 1 by means of lever 3, T g 5 and lever 6 is transferred to roller 8, and due to rotation of roller 8, the subsoiler located in front of the first plow body is shifted to the position shown in FIG. 1 with a dotted line, and simultaneously the HHO is brought to the same position and the other subsoilers as the angular lever 17 rotates at an angle exactly equal to the angle of rotation of the roller 8. To be able to change the depth of the subsoiler, the submersible, ha 5 has a mobile, for which the lever 3 has several holes 4 for bolts that serve to connect it with a thrust 5; Holes 4 are located along an arc of a circle described from the center of the lug 25 of the lever 6 with the upper, unloaded position of the tillers, so that the lever 6 remains in at rest when shifting the gi 5, i.e., subsoiler 20, when raised, returns to the same position, regardless of the depth of descent.

The plow modification with the submersibles consists in the TOJM, which is one shoulder of the pivoting lever 17 (Fig. 3), on which the spring arm 14 of the rear subsoiler is fixed, connected with the help of the hinge bar 15 with the lever 26 on the roller 8 supporting the front-digging lever 13 paws connected by a chain 21 to the stand 12, the S roller supports the lever 27 connected to the thrue 28. On the last there is a slot 29, which includes a pin 30 of the lever 31 sitting on the knee axis 1 of the field wheel 2. In addition, the roller in supports lever 32 connected using the spring 33 with the lever 34 fixed on the axis of the field wheel, and on the roller 8 there is a lever 35, and the handle 36 is connected to the stop screw 37.

To transfer the plow into working position, the crankshaft axis 1 of the field, wheels 2 are rotated. At the same time, the roller 8 and the subsoilers 20 begin to rotate under the action of their own weight and spring 33, which is pulled by the rotation of the axis of the field wheel ;. Roller 8 with the submersibles rotates only until the stop screw 37 rests on the movable stop 38 grams. After that, the axis of field field 1 continues to rotate, at which the pin 30 slides in the slot of 29 tons 28 and rotates it with respect to the lever 27, KaiK is shown in FIG. 3. By appropriate installation of the stop screw 37, it is thus possible to regulate the depth of the subsoiler submersible within the limits within independent limits irrespective of the depth of submersible of the hulls. To pull the plow, the axis of the field wheel is rotated, so that the subsoilers are removed from the soil.
