Description

The utility model relates to agricultural engineering, in particular to tools for tillage, and can be used for surface tillage of the soil in the spring against the autumn background, before sowing and for caring for fallows.

The harrow is known [Copyright certificate RU patent No. 520063, IPC class. A01B 19/00, 1976], containing a frame, a mechanism for connecting to the tractor, support wheels and two batteries of needle disks mounted on the shafts, mounted in series on the frame. The rear battery beam is rigidly connected to the harrow frame and has a band brake mechanism, connected by one branch to the harrow frame through a spring, and the other to the front battery beam hinged to the frame through a tension adjusting mechanism. This design provides additional deepening force on hard soils; however, along with maintaining uneven depth of treatment, energy intensity increases. Extra energy is spent on the friction forces in the braking mechanism. The needles of the rear battery also slip in the soil, changing the quality of processing for the worse.

The closest analogue to the claimed one, adopted as a prototype, is a rotary-type soil loosening device [Copyright certificate RU patent No. 2486731, IPC class. А01В 35/26, А01В 21/08, А01В 39/18, 2013], containing a frame, an automatic coupling bracket, support and transport wheels controlled in height by a hydraulic cylinder and two batteries of needle disks mounted sequentially on the frame, mounted on shafts connected by a chain drive .

The disadvantage of the prototype is the insufficient depth of cultivation, low leveling ability and insufficiently effective destruction of rooted weeds without cutting them, which reduce the quality of work during surface tillage of the soil in the spring against the autumn background, before sowing and when caring for fallows.

The technical result of the utility model is to improve the quality of work.

The technical result is achieved due to the fact that both batteries of needle disks are located behind the support wheels, and a number of universal pointed paws are installed in front of the wheels.

This set of essential features ensures that the inventive combined tillage implement has new properties that are different from the prototype.

Thus, the declared features of the utility model meet the “novelty” criterion.

In fig. Figure 1 shows a diagram of a combined tillage implement, side view;

in fig. 2 - the same, top view.

A combined tillage implement containing a frame 1, an automatic coupling bracket 4, support-transport wheels 3, height-controlled by a hydraulic cylinder 2 and two batteries of needle discs 7, 9 mounted sequentially on the frame, mounted on shafts connected by a chain drive 8, both batteries of needle discs located behind the support wheels, and in front of the wheels there is a row of universal pointed paws 5.

The combined tillage implement works as follows.

Before work, the combined tillage implement is attached to the tractor using an automatic coupler bracket 4 of a known design. Hydraulic cylinder 2 is connected with hoses to the tractor hydraulic system. They lift the harrow with the tractor’s hydraulic lift and drive onto the adjustment platform, where they adjust the soil tillage depth with pointed tines to 10…12 cm, and with the needles of 6 needle disks to 4…10 cm, using a well-known method [Klenin N.I., Sakun N.A., Agricultural and land reclamation machines - M.: Kolos, 1994. - P. 117, 151].

In the paddock, at the beginning of the working stroke, the lever of the tractor hydraulic distributor, which controls the height position of the hydraulic attachment, is set to the floating position. In this case, the combined tillage implement is lowered until the wheels 3 stop on the soil surface, and the universal pointed paws 5 and needle disks are buried with their needles to the adjusted depth. According to [3, P. 139], universal pointed paws 5 cut weeds, crumble the soil and level the microrelief. The needles 6 engage with the soil to the adjusted depth and begin to rotate, loosen the soil and comb out the weeds cut by the pointed paws 5 to the surface.

Thus, compared to the prototype, the levelness of the field surface and the efficiency of weed destruction and cutting are increased, which improves the quality of work.

Thus, the stated technical result is achieved.
