RU143494U1 - WORKING BODY FOR FERTILIZER - Google Patents

Abstract

A working body for fertilizer application, comprising a gullet stand with a divider and a chisel, characterized in that it is equipped with a knife with a fertilizer located at an angle of 30-45 °, moreover, the knife has a cutting edge formed by an oblique angle, located at an acute angle to the horizontal the transverse plane and bolted to the rack with bolts with an internal hexagonal half-secret head, and on the back of the rack is bolted a plate to which the fertilizer is welded, while the fertilizer is made with a smooth bend radius .

Description

The utility model relates to agricultural engineering, namely to the working bodies for fertilizing the soil when cultivating crops.

A known method of fertilizing, including cutting cracks in the soil and the distribution of fertilizers in them, followed by termination of the latter. (See AS 229859 USSR No. Cl. MKI A01B 49/06, publ. 1967).

A fertilizer applicator that implements the indicated method includes a frame on which vertical racks with openers and pipelines are fixed (See AS 974957 USSR No., Cl. MKI A01B 49/06, publ. 1982).

There is also known a method of applying fertilizers, including cutting cracks in the soil and the distribution of fertilizers in them, followed by termination of the latter. A device for applying fertilizers, implementing the specified method, contains a knife fixed to the rack of the working body.

The fertilizer application method and device for its implementation, selected as a prototype, have their drawbacks, as fertilizers are arranged horizontally, such a distribution of fertilizers impairs their use. For example, when fertilizers are applied to a shallow depth, they are used by plants only in the initial period of their development, but when the roots of the plants go to a greater depth, the fertilizers become inaccessible to the roots. When fertilizers are applied to a greater depth, plants begin to receive nutrition already with a fully developed root system and enough moisture at this depth.

The technical task of the proposed working body is to improve the design for the introduction and improvement of the use of mineral fertilizers.

To do this, on a rack of glue, at a given level, holes are drilled with an internal thread with the possibility of fixing a knife with a fertilizer on them. In this case, the knife with the fertilizer is located at an acute angle to the horizontally transverse plane and the cutting of cracks is done at an angle of 30 ... 45 °.

The figure 1 shows the working body of sclerosis, which consists of a rack 1, a bit 2 and a divider 3 to reduce the resistance of the working body. On the rack 1, a knife with a fertilizer is screwed, consisting of a knife 7 and fertilizer 6. Plates 4 for additional fastening of the fertilizer 6 by electric arc welding from the back of the slot of the slot machine 1. The plate 4 is fastened with two bolts 5.

The figure 2 shows a section B-B method of fastening a knife 7 with fertilizer 6 on the rack slitherese 1 using three bolts 8 with an internal hexagonal half-secret head. In addition, the fertilizer has a smooth bending radius R, allowing unhindered passage of mineral fertilizers.

The figure 3 shows a view A, where the fertilizer knife 6 and 7 is located at an acute angle β to the horizontal transverse plane, and the cracks are cut at an angle of 30 ... 45 °, the working width b and the installation height a. The shaper 6 is welded to the plate 4 by means of electric arc welding. The plate 4 is screwed with bolts 5 to the back of the slot.

Figure 4 shows a section CC of a fertilizer knife, with a knife 7 and a guide 6. The knife 7 has a cutting edge with a bevel angle α located at an angle γ, the upper welded portion of the guide part of the fertilizer is located at an angle γ ₁ .

A working member for fertilizing, comprising a slit rack with a divider and a chisel located at an angle of 30 ... 45, characterized in that it is equipped with a knife with a fertilizer, the knife having a cutting edge formed by an oblique bevel, located at an acute angle to the horizontal transverse plane and bolted to the rack with bolts with an internal hexagonal half-secret head, and on the back of the rack is bolted a plate to which the fertilizer is welded, while the fertilizer is made with a smooth bend radius .

The working body is a knife with a fertilizer used in the technology of strip tillage works as follows. When the unit moves along the field, the knife with fertilizer is buried in the arable layer of soil and forms inclined slots. the transverse plane and the cutting of cracks produced at an angle of 30 ... 45 °. In this case, the knife cuts cracks with partial crumbling of the soil, and the fertilizer brings fertilizer. After the device passes in the arable layer of soil, fertilizers are distributed in the form of inclined strips at a given level.

This application of fertilizers eliminates their volatilization, flushing and weathering from the soil surface and ensures uniform nutrition of plants throughout the growing season from germination to full ripening, eliminates plant nutrition as a separate technological operation, allows the use of natural processes to prepare the soil, thereby improving agrotechnical requirements .
