Slit Aggregate - Drawings

Introduction

Currently, one of the priority areas for improving tillage machines is increasing productivity. The use of high-performance machines and tools allows you to save fuel, perform the plowing process in strict agrotechnical terms, which means that it contributes to high yields with less cost.

The base machine is the SCHZN-1,5 slit-fill.

In order to increase productivity, the basic slit model was modernized: two shotguns were installed, the deflector was bifurcated, and the mechanism for adjusting the slit width was simplified. The design of the new slit is a combination of several promising technical solutions. As a result of new design solutions, the mass of the machine increased slightly, which led to an increase in the cost of fuel and lubricants. In this regard, it became necessary to calculate cost-effectiveness.

1.1 Water erosion and soil protection methods

1.1.1 Water erosion and its consequences

Water erosion is the destruction and demolition of soil and loose rocks by water. It is observed wherever surface water runoff occurs. According to the degree of destruction, erosion can be divided into two types: normal, which does practically no harm, since the soil horizon is immediately restored as a result of the soil education process, and accelerated, in which soil destruction goes much faster than restoration.

Depending on the nature of the destruction, accelerated erosion is divided into planar, in which the topsoil is destroyed along the entire plane, and linear, as a result of which the lower horizons are destroyed to a significant depth, sometimes reaching 70-100 mm [4].

The effects of water erosion are devastating and very diverse. Surface flushes destroy the humus horizon, reduce the content of organic matter and humus in it, wash out the main elements of plant nutrition.

By the degree of manifestation of water erosion, the soil can be divided into strongly, medium- and slightly washed. On strong and medium washed soils, which number about 10-11 million hectares, 70-80% of the crop is not obtained, on weakly washed (about 20 million hectares). - 40-50%. Grain shortage according to approximate estimates is about 11 million tons [4].

Water erosion also damages other sectors of the national economy. Erosion products pose a great danger to hydraulic engineering

Process Part

2.1.2 Selection of the workpiece production method

Given the shape of the structure, the best way to obtain it is to weld from three parts: two stamped trunnions and one pipe 108 * 10 produced by rolling.

2.1.3 Development of the processing route according to the task

Taking into account the selected bases, as well as the need for priority treatment of surfaces serving later as technological bases, we choose the following sequence of operations:

005 - Boring

010 - Current

015 - Grinding

020 - Milling

025 - Vertical Drill

030 - Welded

035 - Current
