RU211584U1 - COMBINED WORKING BODY FOR CULTIVATOR-FLAT CUTTER - Google Patents

Abstract

The utility model relates to agricultural engineering, in particular to the working bodies of tillage machines. The combined working body for a cultivator-flat cutter consists of lancet shares fixed in front on a shoe, in the upper part of which expanders are installed behind the shares, under which sprayers are mounted, while reflectors are fixed on the expanders at an angle of 45 ° at a distance that ensures overlapping of spray torches of neighboring sprayers, and the sprayers are located in increments of 2 times less than the width of the spray cone at the reflector. EFFECT: increase in soil fertility and increase in yield by installing sprayers with a step 2 times less than the width of the spray cone at the reflector, which ensures uniform intrasoil application of liquid complex fertilizers to the bottom of the furrow due to overlapping spray cones of neighboring sprayers.

Description

The utility model relates to agricultural engineering, in particular to the working bodies of tillage machines.

The closest to the proposed device in terms of technological solution is a combined working body for a cultivator-flat cutter, consisting of lancet shares, fixed in front on a shoe, in the upper part of which expanders are installed behind the shares, under which sprayers are mounted, reflectors are fixed on the expanders at an angle of 45 ° at a distance that overlaps the spray torches of adjacent nozzles. (RU 206254 U IPC А01В 49/04).

A disadvantage of the known device is the uneven supply of liquid fertilizers to the bottom of the furrow in the zone of overlapping spray torches, since the greater the distance from the nozzle, the lower the concentration of the solution of liquid complex fertilizers enters the soil.

The technical problem to be solved by the claimed utility model is to increase the uniformity of applying liquid complex fertilizers to the soil.

EFFECT: increase in soil fertility and increase in yield by installing sprayers with a step 2 times less than the width of the spray cone at the reflector, which ensures uniform intrasoil application of liquid complex fertilizers to the bottom of the furrow due to overlapping spray cones of neighboring sprayers.

The specified technical problem is solved by a combined working body for a cultivator-flat cutter, consisting of lancet shares, fixed in front on a shoe, in the upper part of which expanders are installed behind the shares, under which sprayers are mounted, and reflectors are fixed on the expanders at an angle of 45 ° at a distance providing overlapping spray torches of neighboring sprayers, which prevent soil from falling onto the spray jet, the sprayers are located in increments of 2 times less than the width of the spray torch at the reflector.

The proposed utility model is illustrated by drawings.

In FIG. 1 - combined working body for a cultivator-flat cutter, top view.

In FIG. 2 - combined working body for a cultivator-flat cutter, side view.

The combined working body for the cultivator-flat cutter consists of lancet shares 1, fixed in front on the shoe 2. In the upper part of the shoe, behind the shares, there are extensions 3, under which sprayers 4 are mounted. Reflectors 5 are fixed to the extensions at an angle of 45 °. nozzles 1 and 3, the spray pattern of nozzle 2 is superimposed, which ensures a higher uniformity of fertilizer application to the soil.

The technological process of work is carried out as follows.

When moving in the soil, the shares 1 cut the soil layer and feed it to the expanders 3. When leaving the expanders 3, the loosened soil layer under its own weight crumbles to the bottom of the furrow.

Due to the fact that the working body for the flat-cutting cultivator moves forward, a cavity is formed under the expanders. Liquid fertilizers are fed horizontally into this cavity from nozzles 4 mounted under the expanders in a flat jet. The jet hits the reflector 5, mounted on the expanders at an angle of 45°, changes its direction and hits the bottom of the furrow. The atomizers are installed in such a step that the spray torch of the nozzle 2 is superimposed on the spray torches of nozzle 1 and 3, which ensures a higher uniformity of fertilizer application to the soil.

Thus, the claimed design of the combined working body for a flat-cutting cultivator makes it possible to improve the uniformity of the distribution of fertilizers at the bottom of the furrow along the width of the working body, thereby increasing soil fertility and increasing productivity.
