Description

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

Known working body of the deep-ripper (RU, patent No. 2263429. C1. IPC. Class ⁷ А01В 13/08, АВВ 13/16. Working body of the deep-ripper / V.P. Zvolinsky (RU), S.V. Klimov (RU), MM Shagaipov (RU), AM Saldaev (RU) - Application No. 2004124956/12. Announced August 16, 2004. Publish. November 10, 2005. Bull. No. 31) comprising a stand with a blade on the front and a conical tip made in in the form of a cut-off part of a hollow cone formed by a secant plane parallel to the axis of symmetry of the cone. The conical tip with the bottom of the rack is connected by a pair of mounting pins located in the technological holes of the conical tip and bonok. Bonks have a mating conical surface mating with the cavity of the cut part of the cone. Such a constructive implementation, allows to reduce energy consumption for crumbling soil.

A disadvantage of the known device is the short-term fastening of the conical tip in the form of a cut-off part of the hollow cone to the bonks with a pair of mounting pins. Under the influence of alternating loads from the side of the cultivated soil on the conical tip, the holding mounting pins in the bonks deform the landing holes, which will lead to a backlash between the rack with bonks and the conical tip, with further separation from the rack with bonks of the conical tip.

The working body of the deep-ripper is also known (RU, patent No. 2251832. C1. IPC. Class ⁷ А01В 13/08, АВВ 13/16. Deep-ripper / SA Pankov (RU). - Application No. 2004116859/12. Declared 03.06. 2004. Publish. May 20, 2005. Bull. No. 14) including a knife-shaped stand inclined to the horizontal and the direction of movement with a pointed frontal face and a paw fixed in the lower part of the stand, made as a part of a hollow cylinder separated by a section plane forming an elliptical cutting edge. The paw with the bottom of the rack is paired with pairs of cylindrical pins placed with the possibility of dismantling in the mounting holes of the paw and the racks of the rack. The deep-ripper provides high quality loosening of soil horizons with a significant reduction in energy consumption.

A disadvantage of the known device is the short-lived fastening of the legs, in the form of a part of a hollow cylinder separated by a section plane for the formation of an elliptical cutting edge, to the joists by pairs of mounting pins. Under the influence of alternating loads from the side of the cultivated soil on the paw, the holding mounting pins in the bonks deform the landing holes, which leads to a backlash between the rack with bonks and the paw, with further separation from the rack with bonks of the paw.

Also known is the working body of the deep-ripper (US patent No. 6401834. B1. IPC. Class ⁷ AB 01/13. Earth working tool assembly / Allan James Yeomans (AU). - Application No. 09/612701. Announced Jul. 10, 2000. Publ. Jun. 11, 2002.) comprising a rack the lower part, which is made in the form of a dihedral wedge, the edges of which, equipped with eyes, meet at an acute angle entering the dihedral wedge-shaped groove of the body of the paw reliably connected by the friction force arising between the conical surfaces. To prevent the legs from coming off conical surfaces, an edge pin is inserted through the hole of the leg and rack eyes, which are bent from the outside of the leg. The construction of the paw is made of various functional elements designed to expand the scope of application in the treatment of soils with various properties, firmly held by a screw with a stand. The deep-ripper provides high quality loosening of soil horizons with a significant reduction in energy consumption.

A disadvantage of the known device is the cross-sectional area of the rack in the lower part, where it takes the form of a dihedral wedge at an acute angle of the paw entering the dihedral cone hole, which under lateral loads leads to breakage of the rack at the entry point of the acute angle of the dihedral wedge in the paw, causing a low design reliability, from lateral forces.

Also known is the working body of the deep-ripper (GB, patent No. 2402313. A1. IPC. Class ⁷ AB 35/22. Tine shoe securing arrangement / John A Biggs (GB). - Application No. 0312957.4 Announced 05.06.2003. Publish. 08.12.2004 .) which is the prototype of the claimed technical solution. The working body contains a rack with holes for attaching to the implement’s frame, a pointed frontal side for fastening the fairing, and a lower part in the form of a dihedral wedge, the lower side of which has a gear protrusion of the attachment to the protrusion on the lower face of the dihedral wedge-shaped groove of the paw body, the sole of which is arrow-shaped , the upper face of the dihedral wedge-shaped groove of the paw body has a recess for entering the protrusion of the fairing fixing the paw on the rack when the opposite end of the fairing is pulled by a clamp with a tightened bolt m.

However, the size of the acute-angled dihedral wedge of the rack is selected less than the angle of the wedge-shaped groove of the paw body, which allows the rack to protrude to the protrusion of the lower face of the wedge-shaped groove of the paw body, while the normal cross-sectional area of the acute-angled dihedral wedge of the rack reaches a maximum value equal to the opening area of the wedge-shaped groove of the paw body if the cross section passes normal to the upper face of the acute-angled dihedral wedge of the rack and through the top of the serrated protrusion of the lower face is acute-angled about a dihedral wedge of the rack, allowing you to enter an acute-angled dihedral wedge of the rack through the hole of the wedge-shaped groove of the paw body, then rotate the wedge-shaped groove of the paw body around the top of the acute-angled dihedral wedge of the rack to engage the serrated protrusion of the lower face of the acute-angled dihedral wedge of the rack with the protrusion of the lower face of the wedge-shaped groove of the paw body, as a result, the normal section of an acute-angled dihedral wedge of the rack along the section of the hole of the wedge-shaped groove of the leg body has an area less than sparing the holes of the wedge-shaped groove of the body of the paw, causing the destruction of the wedge of the rack along a normal section having a minimum value of the area from the forces exerted on the paw moving inside the soil layer.

The disadvantage of this technical solution is the minimum value of the normal cross-sectional area of an acute-angled dihedral wedge of the rack along the section of the hole of the wedge-shaped groove of the paw body, along which the acute-angled dihedral wedge of the rack is destroyed, which is the reason for the low reliability of the structure due to the forces applied to the paw when moving inside the soil layer .

The objective of the invention is to increase the reliability of the structure by increasing the normal cross-sectional area of the polyhedral wedge of the rack to the normal cross-sectional area of the hole of a single-angle wedge-shaped groove of the leg body.

To solve the problem in a known working body, the lower part of the rack is made in the form of an acute-angled dihedral wedge having a toothed protrusion on the lower face, along the top of which passes a normal section of the rack, the area of which is equal to the opening area of the wedge-shaped groove of the leg body, allowing an acute-angled dihedral wedge of the rack with a smaller angular than the dihedral wedge-shaped groove of the paw body, freely, until the convex top of the acute-angled dihedral wedge of the rack contacts with the concave edge of the dihedral to of the pivotal groove of the paw body, push the dihedral wedge of the rack into the wedge-shaped groove of the paw body, and then rotating the flat dihedral wedge of the rack inside the dihedral wedge-shaped groove of the paw, firmly fix the paw body to the rack by engaging the serrated protrusion of the acute-angled dihedral wedge of the rack with the protrusion of the lower face of the wedge-shaped groove of the case paws, then introducing the protrusion of the fairing into the recess of the upper face of the wedge-shaped groove of the paw body, and turning the fairing along the arc around the deepening of the upper face of the wedge-shaped groove of the body The legs make it possible to combine the recesses of the wedge-shaped shape of the fairing with the recesses of the pointed frontal part of the rack, after which the fairing at the location of its recess in the upper part is attracted to the rack with a band clamp tightened by a bolt connection. The paw of the working body attached to the stand, located at an acute angle to the surface to be machined, consists of a single-angled wedge-shaped body, with a recess located inside it in the form of a single-wedge-shaped wedge-shaped groove, on the lower edge of which there is a serrated protrusion, while on the single-sided wedge-shaped body there is a arrow-shaped sole forms, with a recess on the lower part located between the wedge-shaped cutting edge of the sole and the single-angle wedge-shaped body, preventing sticking to the back of the swept shape s flat soles soil and providing high quality of its crumbling while substantially reducing power consumption.

The claimed technical solution differs from the prototype in that a flat asymmetric multifaceted wedge is located on the lower wedge-shaped part of the curved rack, the upper part of which is located above the edge of the wedge in the form of a single-angle wedge, and accordingly the lower part located below the edge of the wedge in the form of a curved wedge. The lower part, in the form of a curved wedge, has a wedge-shaped ledge to accommodate a dihedral flat wedge equipped with a through hole parallel to its edge. A dihedral flat wedge is placed in a wedge-shaped ledge so that its upper face is parallel to the lower face of the wedge-shaped ledge of a curved wedge, and the faces are interconnected. A pin is inserted through a through hole of a dihedral flat wedge, coaxially aligned with a through hole in the walls formed in a single-leg paw body, a single-wedge-shaped groove, the edges of which are held in the walls. The part of the pin located between the paw walls has a section smaller than the edges in the paw walls, freely located in the hole of a flat dihedral wedge, when the flat dihedral wedge is displaced relative to the paw walls, the alignment of the dihedral wedge hole and the hole of the paw walls is violated, the side wall of the dihedral wedge abuts the shoulder of the pin, not allowing the pin to exit the hole of the dihedral wedge.

Connected by a pin not aligned with the holes of the arrow-shaped body and dihedral flat wedge located in the groove of the arrow-shaped body represent an entire assembly unit. The body of the arrow-shaped paw is rigidly connected to its sole, made in the form of a sinusoidal shape of the protrusions on the surface of the direct hollow cylinder, and represents a generally arrow-shaped paw.

The arrow-shaped paw connected by a pin with a flat wedge inside the groove of the paw body assembled on the lower wedge-shaped part of the curved rack forms between the outer surfaces of the non-symmetrical wedge of the rack and the surfaces inside the assembled arrow-shaped paw of the joint, wedging together to form an entire assembly unit, when the arrow-shaped paw is displaced along the lower wedge-shaped part of the curved rack, swept legs on the rack.

The arrow-shaped paw on the rack for jamming with the formation of the whole assembly unit is pressed by a thrust ring, which, when shifted upward, enters the lower wedge part in connection with the wedge stop on the bottom of the rack, causing the thrust ring to press the arrow-shaped leg.

The thrust ring in the upper part from the inside has a flat part, on which the cowl presses with a flat protrusion of its lower part. The fairing, in turn, has an internal curved groove, which is fixed on the pointed frontal face of the rack, and is held on it by a band clamp at the location of the recess in the upper part of the fairing, tightened by a bolt connection.

On the assembled working body, the paw fixed to the stand consists of a single-wedge-shaped body to which a convex sole is rigidly attached with an arrow-shaped shape, in the form of sinusoidal protrusions on the surface of a direct hollow cylinder, allowing the paw to crumble the soil structure with the formation of cracks along the normal to the convex surface, at the same time, the sole of the paw having an internal concave surface does not allow the soil to adhere, providing high quality of its crumbling with a significant reduction energy consumption.

Presence of signs “on the lower wedge-shaped part of the curved rack there is a flat asymmetric multifaceted wedge, the upper part of which is located above the edge of the wedge in the form of a single-wedge wedge, and accordingly, the lower part below the edge of the wedge is in the form of a curved wedge” and “the body of the paw ... consists of a single-sided wedge” wedge-shaped body, with a recess located inside it in the form of a single-angled wedge-shaped groove, "allows you to place the wedge-shaped part of the rack in the body of the paw providing a flat fit stey odnoskosogo rack wedge odnoskosym wedge groove by the action of the largest values dynamically varying external forces from the treated soil and from the exciter of vibrations, mounted on the frame guns to reduce the tractive resistance, improving the joint strength by increasing the contact area between the connecting member. An increase in the strength of the connection between the rack and the foot is achieved by giving equal values to the width of the "multi-faceted wedge of the rack" and the width of the "single-angle wedge-shaped groove" under this condition, the cross section of the load bearing normal surface of the paw takes a maximum value.

The presence of the sign “arrow-shaped paw connected by a pin with a flat wedge inside the groove of the paw body assembled on the lower wedge-shaped part of the curved rack forms between the outer surfaces of the non-symmetrical wedge of the rack and the surfaces inside the assembled arrow-shaped paw of the joint, wedging together to form an entire assembly unit, when shifted arrow-shaped legs on the lower wedge-shaped part of the curved rack, arrow-shaped legs on the rack "makes it possible, in cases when it rests against the inside of the soil against limoe obstacle, move the rack working body with paw attached to it, keeping all parts in the non-state, inside the soil layer in the opposite direction of its arrow.

The presence of the sign “thrust ring which, when shifted upward, enters the lower wedge part into connection with the wedge stop on the bottom of the rack, causing the thrust ring to be pressed by the arrow-shaped ring”, makes the connected structural elements collapsible without the use of special tools or devices. It is enough to release the thrust ring from the vertical force created by the platform of the fairing fixed on the pointed frontal face of the rack, and held on the rack, at the location of its recess in the upper part of the mounting collar, tightened by a bolt connection, as it will weaken the fastening of the paws on the rack under a small effort on the wedge stops , after which it can be disassembled after removing the pin.
