Description

The invention relates to forestry engineering, in particular to seeders, which provide the preparation of a sowing place in a stump (root pass), the supply of fertilizers, soil and seeds to the root pass.

A known machine for the preparation of a seat and fertilizer in the soil (and.with. No. 1021372, AC 5/00, analogue, 1982). It consists of auger drill, fertilizer hopper with sowing apparatus and fertilizer pipelines with a monoblock arrangement of tillage and fertilizer working bodies. The disadvantage of this machine is the incompleteness of the technological process of sowing seeds in the stumps of cut trees.

A device for sowing is known (a.s. No. 1489596, АВВ 49/06, 06/30/89. Bull. No. 24, prototype) containing a hopper for seeds and fertilizers with a seven-pipe, a screw drill with hydraulic drive, a mill with a drive for its rotation and deepening into the soil, gripper and vehicle hitch system. The disadvantage of the prototype is the inability to destroy the growth and vegetation around the stumps.

An object of the invention is to expand the technological capabilities of a seeder combined on stumps by installing a continuous action herbicide tank in the hopper and creating injection channels with spray tips in a gripping device, which makes it possible to destroy the shoots and vegetation around the stumps.

This task is achieved by the fact that in the stump combination seeder containing a fertilizer hopper with fertilizer ducts, a screw drill, a milling cutter with a drive for its rotation around the axis and a drive for deepening, a gripping device and a hitch system for the vehicle, according to the invention, a herbicide reservoir is installed in the hopper continuous operation, and the gripping device is equipped with internal discharge channels facing its lower part, equipped with spray tips installed at an angle of 45 ° to the vertical in the side of felling.

In contrast to the prototype, the installation of a seeder combined on the stumps of the continuous herbicide tank in the hopper of the seeder and supplying the gripping device with discharge channels that go to its lower part, equipped with spray tips installed at an angle of 45 ° to the vertical to the cutting side, will allow to destroy the shoots and vegetation around stumps, which leads to the expansion of its technological capabilities.

The figures explain the general principle of a seeder combined on stumps:

Figure 1 - General view of the seeder combined on stumps.

Figure 2 - view a of figure 1

Figure 3 - view B of figure 2

The combined seeder on the stumps consists of a hopper 1 (Fig. 1) with seed and fertilizer compartments provided with metering devices for fertilizer and seeds (not shown), and pipelines 2, as well as a tank 3 for continuous action herbicides, which is pivotally connected to the system hinges 4 of vehicle 5, the hitch system of which is mounted on a rotary column 6 (for example, on a self-propelled chassis T-16M or on the basis of a tractor UM3-6AL). A guide flap 7 is rigidly attached to the bunker 1. An adapter plate 9 is freely mounted on the drill 8, on which a gearbox 10 and a hydraulic motor 11 are fixed rigidly. The linkage system 4 is pivotally connected to the adapter plate 9 by means of a hydraulic cylinder 12. The hopper 1 is connected to the adapter plate 9 when the help of hydraulic cylinders 13 and 14 of double action, and the front side by means of a rod 15 is rigidly connected to a gripping device 16, driven by a hydraulic cylinder 17.

The gripping device 16 is provided with internal discharge channels 18 (figure 2). At the bottom of the gripper 16, spray tips 19 are installed (FIG. 3). The hopper with the rear side using flat hinges 20 and 21 is connected with rods 22 and 23, on which the milling cutter 24 is mounted, driven by a hydraulic motor 25. The rods 22 and 23 are rigidly fixed to each other by means of a plate (not shown), which is connected to the rear side hopper 1 using the hydraulic cylinder 26.

The seeder combined on stumps works as follows.

The vehicle hitch system 5 lowers the hopper 1 with a gripping device 16 rigidly fixed to it, provided with internal discharge channels 18, which are connected to the spray tips 19, onto a stump of a sawn tree. The gripping device 16 with the help of the hydraulic cylinder 17 grabs the stump, fixing the drill 8 relative to the stump. The drill 8 is driven into rotation through the gearbox 10 from the hydraulic motor 11, and the double-acting hydraulic cylinders 13 and 14 lower the drill 8, the adapter plate 9, the gearbox 10 and the hydraulic motor 11 to the end of the stump and provide the development of a root passage. Then, in reverse stroke, the double-acting hydraulic cylinders 13 and 14 return the drill 8, the adapter plate 9, the gearbox 10 and the hydraulic motor 11 to their original position. The continuous action herbicides supplied under pressure from the reservoir 3 through the internal injection channels 18 to the spray tips 19 process the boundary zone around the stump.

Fertilizers placed in the fertilizer compartment of the hopper 1 are fed by the metering device through the seed duct 2 to the root passage. Then the cutter 24, driven into rotation by a hydraulic motor 25 and deepened using a hydraulic cylinder 26, delivers a fertile soil layer to the guide flap 7 and then to the root passage. Then the seeds located in the seed compartment of the hopper 1 are fed by the sowing apparatus through the seed duct 2 into the root passage. Milling cutter 24 again feeds the fertile soil layer to the guide flap 7 and then to the root passage, after which the milling cutter 24 returns to its inoperative position by the hydraulic cylinder 26, the gripping device 16 with internal pressure channels 18 and spray tips 19 release the stump and the seeder combined on the stumps using the hitch system 4 and the rotary column 6 moves to another working position without changing the parking position of the vehicle 5. All the executive bodies of the device (hydraulic cylinders 12, 13, 14, 17, 26, hydraulic motors 11 and 25) connected to the hydraulic system of the vehicle and their control is carried out through the valve of this system.

As a result of the use of the invention, it becomes possible to destroy the shoots and vegetation around the stumps, which leads to the expansion of the technological capabilities of the seeder combined on stumps.
