RU2360388C1 - Mounted deep ripper - Google Patents

Abstract

FIELD: machine building.

SUBSTANCE: tractor-mounted deep ripper comprises the frame with attachment fittings, rippers fitted on the frame, and covering elements hinged to the frame rear wall and made up of two aligned drums. The blade tip is mounted at, maximum, 15° to horizon, and taken out forward, relative to the blade bar, for 2/3 of the blade length. Subsurface cultivators are attached to the blade bars to move over the height to set the cultivation depth approximating to 20 cm. The depth of the ripper blade tip travel makes 35 to 65 cm. Two covering drums are furnished with teeth, the first drum being provided with active position teeth, while the second drum being equipped with passive position teeth. Aforesaid teeth are arranged on the drum surface along spiral line, their length being greater on the first drum. The clearance between the adjacent teeth of both drums does not exceed 1.5 cm. The first drum teeth feature the gap of 1 cm between their ends and the second drum cylindrical surface. The first drum features the clearance between its cylindrical surface and soil surface making up to 5 cm.

EFFECT: higher quality of cultivation.

Description

The invention relates to agricultural machinery, in particular to machines for deep loosening of the soil.

Various designs of soil deep-rippers (analogues) are known: GASPARDO firms (prospectus for the Artiglio model cultivator firm), Kverneland firms, domestic-made GRPP-2,3 deep-ripper (Orel, Medvedev plant) and others. Some of these machines, like Kverneland, have a frame with working bodies designed for deep loosening of the soil. Unfortunately, they are not equipped with an additional device for leveling the furrows behind the racks of the cultivators and additional crumbling of the soil to a shallow depth of up to 20 cm. In this regard, an additional pass of other machines for leveling and crumbling the soil after the deep rippers is required. The disadvantages of the analogue: after its passage, unbalanced furrows remain, the high energy intensity of the process of cultivators due to the large angle of crumbling of the bit (20-25 °) and deformation of the formation by the legs. In this case, the paw bits are not sufficiently extended forward relative to the axial lines of the paw racks to ensure formation deformation from bottom to top.

Known mounted hoe ripper adopted for the prototype (Description of the utility model for patent RU 46141 U1. Publ. 06/27/2005, Bull. No. 18), containing a frame with fasteners to the tractor hinged system, rippers mounted on the frame and on the rear wall of the frame pivot-leveling joints are mounted pivotally, consisting of two coaxially arranged shafts with curly corrugated discs, for additional crumbling and leveling of the soil behind the cultivators.

The disadvantage of the prototype is the insufficient cleaning of the working bodies of the device from adhering soil and the high energy intensity of the process of cultivators, because their bits are set at a large angle of crumbling (20-25 °) and are not sufficiently extended forward relative to the axial line of the leg of the paw to ensure deformation of the soil from the bottom up.

The technical solution is to improve the quality of work of the deep-ripper according to the alleged invention.

This object is achieved in that in the mounted mounted subsoiler mounted with a tractor containing a frame with fastening elements to its mounted system, rippers mounted on the frame and on its rear wall are pivotally mounted equalizers consisting of two coaxially arranged drums according to the invention the paw bit is set at an angle to the horizon of no more than 15 ° and is moved forward relative to the center line of the paw post by 2/3 of its length, and the plane cutters are mounted on the paw legs with the ability to move in height to set the depth of the soil layer they cultivate to 20 cm with the depth of the rake paw bit 35-65 cm, and two drums of the leveling arm are equipped with teeth for the active position on the first and passive - on the second, while the teeth are placed on the surface of the drums in a helical line and have a length on the first greater than on the second, the gap between adjacent teeth of the first and second drums does not exceed 1.5 cm, and the teeth of the first drum have a gap of up to 1 cm between their ends and the cylindrical surface of the second drum, while the first araban is installed with a gap between the soil and its cylindrical surface up to 5 cm.

The technical result is an increase in the reliability of the technological process due to the lack of clogging with soil and crop residues of the ripping drums located on the frame behind the paws of the subsoiler, and a decrease in the traction resistance of the machine due to the removal of the paw bit forward relative to the vertical axis of the paw by 2/3 of its length, t. e. so as to ensure deformation of the formation from the bottom up, while the bit has an angle of inclination to the horizon of not more than 15 °.

The analysis of the prior art by the applicant, including a search by patent and scientific and technical sources of information and identifying sources containing information about analogues of the claimed invention, allowed to establish that the applicant did not find an analogue characterized by features identical to all the essential features of the claimed invention. Therefore, the latter meets the requirement of "novelty" under the current legislation.

The invention is illustrated by drawings, where figure 1 shows a diagram of a subsoiler, side view; figure 2 - layout of the teeth on the drums, top view.

The subsoiler includes a frame 1 (Fig. 1), on which there are mounted ripper legs 2 with plane cutters 3 and a chisel 4. In front of the ripper legs 2, a front drum 5, a rear drum 6, which have ripper teeth 7 and 8, respectively, are installed.

The design feature of the paws 2 is that the chisel 4 is located at an angle of no more than 15 ° and is moved forward in front of the rack by 2/3 of the length of the paws to deform the soil in the direction from the bottom up. The plane cutter 3 is mounted on the stand of the paw 2 with the possibility of movement, so that at different depths of the rippers 2 (35; 50; 65 cm), the top layer of soil is treated with plane cutters 4 at a depth of 20-22 cm.

On the ripping drums 5 and 6, the teeth are arranged along a helical line. In this case, the teeth 7 of the first drum 5 have a length greater than the rear. The gap between adjacent teeth 7 and 8 should be no more than 1.5 cm, and between the ends of teeth 7 and the cylindrical surface 6 of the drum should not exceed 1 cm. Such parameters will ensure good cleaning of the rear drum from adhering soil, and a gap of 1.5 cm between adjacent teeth of drums - their cleaning and high-quality crumbling of the soil.

High-quality crumbling of blocks in the upper soil layer and the absence of sticking of the front drum 5 is also ensured by the fact that the length of its teeth 7 is longer than that of the back one, and a gap of up to 5 cm is established between the soil plane and the cylindrical surface of the drum 5. This creates good opportunities for the destruction of lumps soil and rotation of the drums 5 and 6 with different frequencies, which also improves the cleaning of the teeth and surfaces of the drums from adhering soil.

The subsoiler operates as follows. When the machine with the tractor moves across the field, the paws 2 are deepened to the set depth and loosen the soil layer, providing the forward bit 4 to deform it from the bottom up. Flat cutters 3 produce additional crumbling of the upper soil layer to a depth of 20 cm.

An additional device for crushing the soil and leveling over the entire working width is provided by drums 5 and 6 with active-passive arrangement of teeth 7 and 8 and placement along a helical line on their surface.

After the passage of such a machine, the soil has rough crumbling at a depth of 20-65 cm and shallow at a depth of up to 20 cm, as well as a well-leveled surface.
