Description

I

The invention relates to agricultural machinery, in particular, machines for weed control and can be used to introduce herbicides in gardens.

A device for feeding plants is known, comprising a frame on which a container is connected, connected by pipelines with a rod and tips, and a probe II.

It is also known a device for applying herbicides, comprising a frame on which a container is connected, connected by pipeline to a rod, and a probe 2.

A disadvantage of the known device is the uneven distribution of the herbicide, since when the rod is withdrawn from the trunk of trees (or plants), the nozzles are located in one line in the direction of movement of the unit. Therefore, a greater amount of herbicide working fluid is introduced near the tree trunk, which,

The flow through the root system of the tree is negatively reflected on the fruits and is dangerous to human health. After the boom has moved away, a small amount of liquid herbicide is introduced per unit area, due to which it is impossible to completely eliminate weeds in this segment of the plot.

The purpose of the invention is the elimination of damage to plants by the herbicidal liquid.

This goal is achieved by the fact that a device for applying herbicides, including a frame on which a container is mounted, connected via pipes to a rod, and a probe is provided with a hinged valve on the frame, and

Claims (2)

20 is a central and lateral section installed at an acute angle, while the valve of the control valve is connected to the probe, and its body by means of pipelines is with the capacity and the lateral section. . FIG. 1 shows the proposed device, top view, in FIG. 2 the same, front view. A device for applying herbicides in interscivitary strips of gardens consists of a self-propelled chassis 1, with a frame 2 fixed on it, on which is mounted a rod consisting of a central 3 and a side (sections with; sprayers 5 herbicidal emulsion. To frame 2 pivotally {f} hydraulic cylinder 6, which in turn is pivotally connected to bracket 1 with the other end, plate 8 is rigidly attached to the front part of frame 2, to which probe is 9 pivotally attached. 1Dup 9 consists of 10 main and 11 additional arms connected to each other . On the main On the upper arm 10 of the probe 9, a spring 12 is attached, which with its other end is hinged to the plate 8, and the additional arm 11 of the probe 9 is connected via a spring 13 to the bracket 1. A. Limiters 15 and 16 are mounted on the plate 8 on the plate 8 is pivotally mounted a hydraulic distributor 17 with a rod 18, which in turn is pivotally connected to the main arm 10. The hydraulic distributor 17 is connected to the tank 20 for a herbicidal emulsion by means of a pipe 19, and a hose 21 is connected to the side section 4 for supplying the emulsion to the sprayers. section 3 is separated from the side plate 22. The device for copying the soil microrelief, made in the form of a support wheel 23, is fixed on the frame 2. The device operates as follows. When the self-propelled chassis 1 enters the garden frame between frame 2, central 3 and the side sections of the rod, it is transferred to the working position by means of the hydraulic cylinder 6. After this, the herbicidal emulsion is supplied from the container 20 by means of the pipeline 19 through the hydraulic distributor 17 and the pipe 2 to the pipe a sprayer of the lateral section A, spraying between the rows and interstitial strips. The self-propelled 4 | chassis 1 is moved so that the additional arm 11 of the probe 9 with its middle part touches the tree trunk, and the side section passes near the tree trunk at a distance of 250300 mm. When touching a tree trunk, the main arm 10 of the probe 9 rotates, overcoming resistance primarily to the spring 12 and then the spring 13. By turning the probe 9, the stem 18 of the hydraulic distributor 17 moves to the touch of the main arm 10 with the stopper 1b. Thereafter, the additional shoulder 11 of the probe 9 is rotated to the distance from the tree trunk. When moving away from the tree trunk, the probe 9 takes the initial position using depreciation springs 12 and 13, resting against the stop 15, after which the supply of the herbicidal emulsion to the side section 4 begins. This process is repeated upon meeting each tree. The use of the invention makes it possible to reduce the consumption of herbicidal liquid 2.5 times and to exclude damage to the trunks of trees (or plants). Claims An herbicide application device comprising a frame on which a container connected via pipes to a rod is mounted, and a probe, characterized in that, in order to prevent damage to plants by the herbicidal liquid, it is equipped with a hydraulic distributor and the rod is designed as rigidly interconnected central and installed at an acute angle upward side sections, while the valve stem is connected to the probe, and its body by means of pipelines - with capacitive Stew and side section.
