Abstract

Disk tillage implement, including a frame on which the cutting discs are mounted on racks, characterized in that the frame is made of two parts, which are rigidly interconnected by a detachable connection.

Description

The utility model relates to agricultural engineering, namely, to tillage implements for primary processing, in particular to frontal disc harrows.

Currently, there is the problem of using known disk harrows on stony, highly moist soils and soils with high vegetation due to the fact that the inter-disk space is constantly clogged, since their rows are located at a distance of mainly not more than 700 mm from each other. This distance is not enough to work on the soils described above. However, the distance of 700 mm is due to objective reasons, namely, the dimensions of the vehicles, which in turn are tied to the width of the roads, so the frame length can be no more than 2 m 38 cm.

The prior art disk harrow with a cutting unit according to the patent of the Russian Federation No. 66881 (utility model), processing highly moist, stony soils and soils with high vegetation, including a disk stand made in the form of an arcuate spring, rigidly fixed to the frame of the tillage implement. The design of the analogue is such that the work of the tool on stony soils, soils with high humidity and tall grass is possible due to the fact that the disc stand is made in the form of an arcuate spring, but clogging of the discs will still occur due to the small interdisk space.

As a prototype of the proposed utility model selected "Disk plow-cultivator", certificate of the Russian Federation No. 14797. The well-known solution for the patent No. 14797 is applied in a plow-plow-bed cultivator plow PLD3 × 4 (Appendix to the application materials of patent No. 14797, application No.2000104431/20), in which the distance between the disks is 800 mm, therefore, the frame will be longer than 2 m 40 cm ( car body size). The proposed design allows you to process fields with stony soil, moist soil and soil with high vegetation without clogging disks, but transportation of such a plow-cultivator will be difficult, since the frame can be placed in the car body only in a vertical position. The stability of such a frame is not reliable, its additional fastening or transportation in disassembled form is necessary.

The task the utility model aims to provide is reliable and safe transportation of a disk tillage implement, the frame of which goes beyond the dimensions of the vehicle body, at no additional cost.

The problem is solved due to the fact that the frame is made of two parts that are rigidly interconnected by a detachable connection.

Thus, the problem of the utility model is solved.

Figure 1 shows a General view of a disk tillage implement; figure 2 shows the connection of two half-frames of a disk tillage implement.

The disk tillage implement consists of a frame 1, which includes two half frames 2 and 3, rigidly interconnected by a detachable connection, for example, a bolt 4 on the flanges 5. On the frame 1, discs 6 are mounted in rows.

Disk tillage implement works as follows. After transporting the unit from manufacturer to customer

it is being assembled. Frame 1 is assembled from two half-frames 2 and 3 with bolt connections 4 on the flanges 5. On parts 2 and 3 of the frame 1, cutting discs 6 are attached. After that, the implement is aggregated with a tractor and soil cultivation begins.

The possibility of implementing a utility model with the implementation of the task is confirmed by the well-known means and methods. Thus, the possibility of implementing a utility model is confirmed.
