The invention relates to earthmoving machinery, namely, machines for capital planning of agricultural fields with preservation of the upper fertile soil layer.

Known trailed long-base planner, including the supporting frame, front and rear undercarriage and bucket working body located between the wheels 1.

The disadvantage of such a planner is the impossibility of maintaining a constant thickness of the fertile layer throughout the entire planned area in the course of the work, moreover, the underlying and undercutting of the fertile soil layers can be cut with their intermixing.

The closest technical solution to the invention is a long-base planner that includes a supporting frame consisting of a hydraulic cylinder for lifting the front and rear half-wheels with the driving wheels, mounted on the front half-frame, working body, sectional conveyor for moving the cut off soil by the cutting body behind rear wheels, the front section of which is located in front of the bucket working body and is connected with the cutting working body, and the hydraulic cylinder for controlling the latter with the distributor 2 .

However, the well-known planner, although it allows preserving a constant thickness of the fertile layer over the entire planned area, does not exclude cutting the stretcher and undercutting of the fertile soil layers with mixing them together, which leads to a shortage of crops of agricultural crops.

The purpose of the invention is to improve the quality of removal and distribution of the fertile soil layer.

The goal is achieved by the fact that in a long base scheduler, including a carrier frame, consisting of interlocking front and rear half-frame hydraulic cylinders with driving wheels, a bucket working body mounted on the front half-frame, a sectional conveyor for moving the cut off soil by the cutting body behind the rear wheels the section of which is located in front of the bucket working body and is connected with the cutting working body, and the hydraulic cylinder controlling the latter with the distributor, the cutting working body is made in de flat wedge-shaped; 131i) 1 of the knife, which is installed right-sided () of the product boards on the rear half-frame and has a sensor for signaling the difference of specific conpoiHii / ieiuift re, .ani) about pl (); and the base and iodity. () This is associated with the distribution; | Silk Gel 1-Idroi11 ..; And 1dr; 1 control cutting tool, while located behind the wedge-shaped knife end of the front section of the conveyor pivotally connected with the longitudinal bars.

In addition, the difference signal sensor

The specific resistivity to cutting of fertile and underlying mineral soils is made in the form of a front fixed knife and a rear movable knife fixed laterally at the front of the wedge-shaped knife, the cutting edge of which is located 2-3 cm below the cutting edge of the fixed knife.

FIG. 1 shows a long-base scheduler, a general view of the maschina in the working position; in fig. 2 is a diagram of a system for automatically adjusting the depth of digging by a cutting tool.

The long-base planner includes a carrier frame 1 consisting of connected

between the lift cylinder 2 of the front 3 and the rear 4 half-frames with the running wheels 5, the front working body 6 mounted on the front half-frame, the section conveyor 7 for moving the soil cut by the cutting body 8

rear wheels 5, the front section 9 of which is located in front of the bucket tool body 6 and is associated with the cutting tool body 8, the control cylinder of the last 10 with the distributor P, the guide

a flat groove 12, a compacting roller 13, a stripping knife 14, and an automatic depth adjustment system by a cutting tool. The cutting tool 8 is made in the form of a flat wedge-shaped knife, which is installed by means of longitudinal bars 15 on the rear half-frame and has a sensor for signaling the difference of specific resistance to cutting of fertile and underlying mineral soils, which is connected to the distributor 11 of the cutting cylinder of the cutting tool, a wedge-shaped knife the end of the front section of the conveyor 9 is hingedly connected to the longitudinal bars 15. The flat wedge-shaped knife is installed with an angle

cutting 20--25 ° to the horizon.

The sensor signal of the difference of specific resistivity to cutting of fertile and underlying mineral primers is made in the form of anterior fixed knife 16 and a rear movable 17 fixed on the side of the front part of the wedge-shaped knife, the cutting edge of which is located 2-3 cm below the cutting edge of the fixed knife. movable against damage and reduces the forces acting on it from the ground. The system of automatic adjustment of the depth of digging with a wedge-shaped knife also includes

knives 16 and 17, contact box 18, electrohydraulic distributor spool 11, hydraulic cylinders for raising and lowering 10 wedge-shaped knives, accumulator battery, oil pump, tank for working fluid.

Long base scheduler works as follows.

In the process of working the machine, the cutting tool body cuts off the fertile layer in the form of chips of various thickness and directs it to a sectional conveyor that is the same width as the machine. The latter directs the soil along the guide chute 12, which places the fertile layer outside the planner without turning the reservoir onto the surface planned by the bucket working body. A skating rink following the planner produces a compaction of the laid fertile layer, and a stripping knife 14 prepares it. Conveyor 7 consists of three sections interconnected jointly, since the front section must move in a vertical plane with the wedge-shaped knife, and the middle section along with the front frame and the main bucket tool.

The wiper blade is rigidly fixed on the arm of the compaction roller and installed at the back of the latter, since as it cuts and passes through the conveyors, the soil undergoes deformation. If the stripping knife is located in front of the roller, an earth roll is formed from the ground entering through the conveyor, since it is not connected to the main ground. Therefore, the initial soil structure deteriorates. After compaction of the cut soil, it is necessary to make a small layout of the upper part of the soil with a stripping knife.

The signal to the operation of the hydraulic cylinder 10 comes when cutting a fertile layer of different thickness from the movable knife 17 of the sensor, which works on the principle of the difference of specific resistance to cutting of different soils - located outside the fertile soil and iodine styling mineral soil. The fixed 16 and movable 17 knives are fastened to the arm 19, which is fastened on the side of the wedge-shaped knife, in its front part. The spring 20 of the sensor is connected one end rigidly with the bracket, and the other with the upper part of the movable knife of the sensor, and creates the necessary force to return the subspecific knife to its original position while reducing the force in case of a knife falling on the underlying soil.

due to the resistivity, the movable sensor blade deviates from the vertical position and closes the contact a. The signal of the electrohydraulic distributor 11 to the working fluid inlet into the lower cavity of the hydraulic cylinder 10, thereby digging the cutting tool 8, and with it moving knife 17 gauge. Upon recess, the movable sensor blade returns under the action of the spring 20 to the original vertical position, and at the same time opens the contact, returning the electro-hydraulic distributor 11 to the neutral position. When reducing the cutting resistance, the movable sensor blade issues a signal to the electrohydraulic p; Hydraulic sprinkler distributor for hydrodynamic injection of a cutting body 8.

In the proposed scheduler, the i-run is cut off at different thicknesses and without a permeability 2 it goes to the planned surface. The section conveyor allows the soil to be kept in a straight-line movement from the wedge-shaped knife to the conveyor without turning the soil layer.
