Description

The device relates to forestry and agriculture and can be used for loosening, hilling cultivated plants and weeding weeds, and, in particular, on reforestation works to prepare seats for forest crops (seedlings and seedlings).

Planting of forest crops (seedlings and seedlings) on clearings is carried out mainly in spring or autumn. Before planting, soil preparation and cultivation are carried out. For these purposes, use plows, disk or milling tools. In practice, especially when planting in the autumn, the time between processing and planting can be significant. As a result, overgrown grass is prepared for planting sites. This greatly complicates the planting of forest crops using hand-held devices and requires the use of additional tools to prepare the planting sites. As such tools, devices mounted on the worker’s leg can be used.

A device is known for weeding weeds, mounted on a worker’s shoe, including a base on which working bodies are mounted in the front and rear parts, and a mechanism for fixing the base on the worker’s shoe. Working bodies have the ability to change their position relative to the foundation [1].

The disadvantage of this device is that it is unsafe to use, since the worker is not protected from unintentional impact by the working body in the foot area.

Known hoe, mounted on the shoes of the worker, including the base, equipped in front of the working body, and the mechanism for fixing the base on the shoes of the worker [2].

The disadvantage of this device is that when working in harsh conditions (for example, felling conditions) due to interaction with soil and stones, there is a rapid blunting of the cutting edges of the working body, leading to an increase in the effort required to cut the vegetation. By sharpening, you can restore the cutting properties of the working body, however, this will require stopping the planting process. It should also be noted the extreme insecurity of the operation of such a device, since its design does not provide for the protection of the feet of the worker.

The closest analogue, selected as a prototype, is a device for cutting trunks of agricultural crops, mounted on the foot of the worker, including the base, equipped in front of the working body, and the mechanism for fixing the base on the shoe of the worker [3].

The disadvantage of this device is that when the blunting of the working body, work must be stopped to sharpen it. In addition, the device is unsafe to operate.

The technical result, which is directed by the claimed agricultural tool for tillage, mounted on the shoe of a worker, is to increase productivity by providing high cutting properties of the working body, increasing the period between the next sharpening of the working body, as well as ensuring safety and ease of operation.

The technical result is achieved due to the fact that the base is made in the form of front and rear support plates connected by elastic material, provided with protective walls, and the working body has at least two working parts and is mounted rotatably under the front support plate, the front support plate being provided locking mechanism for fixing the working body.

An agricultural soil cultivation tool, fixed on a worker’s footwear, includes a base equipped in front with a working body 1, and a mechanism for fixing the base on the worker's shoes.

The base is made in the form of front and rear support plates 3 and 4 connected by elastic material 2, provided with protective walls 5 and 6, respectively.

As elastic material, for example, rubber or polyurethane fabric can be used.

The working body 1 is rotatably fixed under the front base plate 3 and has at least two working parts 7 and 8. The fastening of the working body 1 to the base plate 3 can be performed using a screw 9. For this, the base plate 3 is provided with a threaded hole 10, and the working body 1 hole 11 under the screw 9.

The shape of the working body, depending on the natural-production conditions, can be different (Fig. 5-7).

The front base plate 3 is equipped with a locking mechanism for fixing the working body 1, which can be implemented in the form of spring-loaded fingers 12, 13 placed in grooves 14, 15 made in the front base plate 3, while the working body 1 is provided with holes 16 for spring-loaded fingers 12 and 13. The spring fingers 12 and 13 are held in the slots 14 and 15 by means of a protective cover 17 fixed to the front base plate 3 with fixing screws 18 and 19. For this, threaded holes 20 and 21 are made in the front base plate 3, and in the protective cover 17 through e holes: 22 for screw 9, 23 and 24 for mounting screws 18 and 19, as well as holes 25, 26 for spring-loaded pins 12 and 13.

To ensure the convenience of removing the working body 1 from a fixed position, a key 27 can be used.

The mechanism for fixing the base on the worker’s shoes can be implemented in the form of tension belts with locks: fore nose 28 and heel 29, mounted on the protective walls 5 and 6, respectively, and fastening 30 connecting the protective walls 5 and 6.

Work using the inventive device is as follows. The worker through the mechanism of fixing the base on the shoe of the worker secures the device on his leg. This is done by tensioning or loosening the tensioning belts with locks 28, 29 and 30. To increase the safety of work, two devices should be used at the same time, since in this case protection is provided for the feet of the worker.

Next, the worker proceeds to landing work. Before the formation of the landing hole is preparing the seat. To do this, cut off the disturbing vegetation and produce loosening of the soil by means of the working body 1, guided by the foot of the worker. Next, the formation of a planting hole and planting of a seedling (seedling) is carried out. After which the worker moves to a new landing site, where the cycle of work is repeated.

In the process, when the working body 1 interacts with soil and stones, its working part becomes dull (for example, 7). To restore the cutting properties of the working body 1, the worker, acting with a key 27 on the spring-loaded fingers 12 and 13, releases it and turns it relative to the screw 9, so that a new working part (for example, 8) is in front of the foot. The fixation of the working body 1 is carried out by combining the holes 16 with the fingers 12 and 13. After which the work continues.

Thus, the device allows to increase the productivity and safety of the preparation of the seat, as well as to ensure ease of use. Productivity increases due to the ability to quickly change the dull working part of the working body 1 to a new one. Improving the safety of work is determined by the presence of base plates (front 3 and back 5), protective walls 5 and 6, as well as a protective cover 17, which protects the foot of the worker from injuries that may result from interaction with the working body 1.
