Description

(5) SOIL PROCESSING TOOLS

one

I The invention relates to an agricultural technique, in particular to tillage tools.

A tillage implement is known, including a frame and a drum with teeth 1 1.

Such a tool is clogged with soil and weeds and produces only superficial soil accumulation.

A soil-cultivating tool is known, including a bar-shaped natural drum and an internal drum placed in its cavity with working elements 2.

The disadvantage of this tool is the poor quality of work, consisting in weak separation of weeds and insufficient crumbling of blocks due to the fact that the working elements of the outer drum do not penetrate the soil and therefore almost do not crush it. The possibility of weed destruction and destruction of the blocks is determined by the likelihood of their meeting with the needles and clearly small, the speed of the n;

The purpose of the invention is to improve the quality of work.

This is achieved by the fact that the outer and inner drums have frictionally coupled pulleys, while the inner drum is fixed by means of tg mounted pivotally on the axis of rotation of the outer drum. The fasteners for fastening the inner drum are adjustable in length and are additionally connected by means of a spring to the axis of the outer drum. An equalizer is installed behind the outer drum.

20 tillage implement, front view; in fig. 2 shows a section A-A in FIG. in fig. 3 shows an example of an inner drum. The tillage implement contains an outer drum 1 with a diameter D and a pulley 2 with a diameter O, eccentrically mounted in drum 1 and a drum 3 with a diameter d with a pulley with diameter d, a equalizer 5, a ballast holder 7, a hitch 7 and a tweeter 8, kinematically matched with it. The outer drum 1 consists of annular disks 9 and s rods fixed to them 10. The pulleys are placed on the bottoms 11 mounted on the disks 9 and bearing bearings 12, in which the axis 13 of the drum 1 is mounted. The inner drum is made in the form of a needle blade or bar rotor, including shaft k and working elements 15. At the ends of shaft 1 there are fixed pulleys interacting with pulleys 2 of drum 1. The shaft is mounted in bearings 16, the shells of which are fixed on length-adjustable rods 17, pivotally mounted on the axis 13. T gami 17 regulate the force of adhesion between the pulleys. To fix the rotor in the working position and to prevent jamming of the slabs when stones and the like hit it. the glands 17 are coupled with torsion springs 18 fixed on the axis 13; Equalizer 5 is fixed on, pull 19) pivotally connected to the trailer device 7 and additionally connected to it by chains 20 equipped with elements (chains) limiting the lowering of the equalizer 5 The box 6 for ballast and scraper 8 is fastened to the hitch 7 by means of racks. The broomstick is made in the form of a metal brush. The surface of the pulley 4 is rubberized. The ratio of the diameters of the drums and the friction pulleys matching them is expressed by the dependence dD l, 2Dd, which ensures that the peripheral speed of the working elements of the inner drum exceeds the speed of movement of the implement. When the width of the gun is small (up to 1 m), the pulleys are installed only on one side. During operation of the tillage tool, the drum 1 is immersed in the treated soil layer with weeds and, rolling, rotates the interacting wheels 2 and i and the drum 3. At the same time, the drum 1 brakes and the rods 10 destroy the lumps, tear the weed root and remove them. surface (separates). The drum 3, while being at a peripheral speed exceeding the translational speed, effectively crumbles the boulders and destroys the weed shoots in the surface layer. The rods of the U drum 1 contribute to the pinching and destruction of the blocks by the working elements 15. The ejection of the soil from the drum 1 is facilitated by the drum 3. The springs 18 prevent it from lifting above the treated layer. However, when the working elements 13 meet with the stones, these are twisted and the drum 3 passes without jamming an obstacle. Weeds hanging on the bars are dropped from them by the scraper 8. Equalizer 5, if necessary, smoothes the treated surface. Thus, high quality tillage is ensured. The tillage implement is effective both for pre-sowing treatment for tilled crops, especially beets, and for grain and winter crops. It can be used both as a standalone unit mounted on the hitch and as part of combined units. With a section width of 2 m and an operating time of 150 ha, the annual economic effect on tillage for tilled crops will be about 300 rubles. for one weapon. Claim 1. Soil-processing tool, including a bar outer drum and an inner drum with working elements placed in its cavity, characterized in that, in order to improve the quality of tillage, the outer and inner drums have frictionally coupled pulleys, while the inner drum is fixed by means of r, pivotally mounted on the axis of rotation of the outer drum. 2. A tillage implement according to claim 1, characterized in that the fastenings of the fastening of the inner drum are made adjustable in length and are additionally connected by means of a spring to the axis of the outer drum. 3. A tillage tool according to claim 1, characterized in that.
