TIRES FOR AN AGRICULTURAL SEEDING AND / OR SOIL TILLAGE EQUIPMENT

Description

[0001] The invention relates to a tire for an agricultural sowing and / or soil cultivation device according to the preamble of patent claim 1 and to an agricultural sowing and / or soil cultivation device according to the preamble of patent claim 11.

[0002] In the field of agriculture, a variety of trailed, mounted, and / or self-propelled implements are known. These include seed drills suitable for spreading material, particularly seed and / or fertilizer, on agricultural land, as well as tillage implements used to prepare and / or post-process the soil of such land. Furthermore, these include combination tillers consisting of a seed drill and a tillage implement, which are designed to perform the spreading of material and the cultivation and / or treatment of the soil in parallel within a single operation.In order to work and / or treat the usable area, in particular the arable soil, accordingly, in particular to compact it, such agricultural implements have at least one tire suitable for this purpose, such a tire being arranged, for example, on a soil cultivation tool assigned to the sowing and / or soil cultivation implement and / or on a chassis, in particular suitable for transport on the road.

[0003] An exemplary machine type with such a tire is described, for example, in DE 10 2008 045 132 A1. The tire described here is part of a coulter arrangement and is designed in the manner of a trailing depth control and / or pressure roller for at least partially compacting and / or pressing the arable soil, in particular soil that has been loosened beforehand. In another area of application, as described in EP 2 005 810 A1, such a tire, in particular in a plurality, is arranged on a roller and designed to prepare the arable soil in advance, in particular before the distribution material is spread. In a further area of application, which is described in DE 20 2010 016 667 U1, such a tire, in particular in a plurality, is arranged on a divided roller in the manner of a tire packer.The tires described in the aforementioned fields of application each comprise at least one tread, in particular a circumferential tread, that can be rolled in a running or circumferential direction of the tire, and a plurality of stud elements, in particular extending radially from the tread. The stud elements are arranged between two opposite lateral ends, in particular edges, of the tread and at least partially one behind the other in the running direction, with at least one of the stud elements having at least one transverse section that is formed substantially transversely, in particular obliquely, to the running direction.

[0004] EP 2 269 431 A1 discloses a roller for agricultural and similar machines, comprising a tubular support that can rotate about an axis and a plurality of semi-hollow tires arranged around the tubular support. The treads of the semi-hollow tires may have lugs.

[0005] US 2020 / 120852 A1 discloses an agricultural roller comprising a tubular support around which pneumatic tires are arranged, the treads of which may have lugs.

[0006] The inventions of EP 1 972 467 A1 and EP 1 810 560 A1 relate to tires used in particular for agricultural equipment, especially rollers. Studs can be arranged along the treads of the tires.

[0007] It has been shown that tires designed in this way have so far been inadequately adapted to the agricultural application described. Soil cultivated and / or treated with conventional tires exhibits, among other things, a high degree of unevenness in terms of compaction and reconsolidation of the soil. Soil compaction is typically more pronounced, particularly higher, in the central region of a cultivation strip created by the tire than at the lateral ends, particularly at the edge, of the respective cultivation strip. This results in particular from the relatively large distance between two lug elements arranged one behind the other in the region of the lateral end, particularly at the edge, of the tire.However, a corresponding increase in the geometry and / or the number of stud elements is not readily possible, as this would result in excessive compaction of the soil by the tires, preventing precipitation in the form of water from penetrating and / or seeping sufficiently into deeper soil layers. Uneven compaction also negatively impacts gas exchange, particularly air exchange, between the relatively unevenly compacted soil layers and / or the prepared rows for the distribution of the material.

[0008] In addition to the compaction of the arable soil, the uneven depth and / or height conditions of the cultivated arable soil and / or the inadequate distribution of the different soil compositions (proportion of fine soil) are also disadvantageous for the deposition of the distribution material.

[0009] The object underlying the invention is therefore to design a tire for an agricultural sowing and / or soil cultivation device in such a way that the uniformity of the cultivated and / or treated soil, in particular the seedbed, is further improved. In particular, the row-specific preparation and / or post-treatment of the soil, in particular the seedbed, for the distribution material and / or the trailing soil cultivation tools is to be further improved.

[0010] This object is achieved according to the invention in that the at least one stud element has at least one first outer section facing a first lateral end of the tread, which is designed at least in sections to correspond, in particular at least almost parallel, to the running direction.

[0011] As a result of this measure, increased compaction or reconsolidation of the soil can be achieved in the area of the lateral end, particularly at the edge, of the cultivation strip, while compaction towards the center of the cultivation strip is at least essentially not further increased. This results in particularly uniform soil compaction.

[0012] The first outer section preferably has a longitudinal direction that corresponds at least approximately to the running direction, wherein a longitudinal direction of the transverse section is oriented transversely, in particular obliquely and / or angled, to the running direction. Furthermore, an outer section of the stud element that extends at least partially in and / or counter to the running direction is preferred. A longitudinally directed extent, in particular length, of the first outer section is preferably approximately one quarter to one third of an extension, in particular length, of the transverse section directed in the longitudinal direction of the transverse section. Such a ratio of the extensions, in particular lengths, enables particularly uniform compaction of the cultivated soil. In an alternative or additional embodiment, the extension of the first outer section can also be less than one quarter of the longitudinal extension of the transverse section.In a further alternative embodiment, the length of the outer section may also be approximately half the length of the transverse section.

[0013] The outer section is preferably formed at an angle to the transverse section, with a right or obtuse angle enclosed between the outer section and the transverse section being particularly preferred.

[0014] The at least one stud element further preferably has at least one transition connecting the outer section to the transverse section, with an at least virtually seamless and / or step-free transition being particularly preferred. The relatively fine or loose soil composition displaced by the tire, in particular fine earth, is guided and / or directed particularly well along the stud element in the direction of the outer section by such a transition. In an alternative embodiment, the stud element can also be at least partially or almost completely interrupted between the outer section and the transverse section.

[0015] In a preferred embodiment of the tire according to the invention, the stud element has at least one inner section which, viewed in the running direction, is arranged laterally opposite the first outer section, and in particular facing away from the first lateral end of the tread, wherein the inner section is preferably at least partially mirror-symmetrical to the first outer section. The stud element is preferably mirror-symmetrical with respect to a sectional plane which is in particular oriented at least substantially perpendicular to the longitudinal direction of the transverse section. Preferably, the first outer section is arranged at a first, in particular outer, end of the transverse section and the inner section is arranged at a second, in particular inner, end of the transverse section. The stud element is preferably substantially Z-shaped viewed transversely to the running direction.Due to the at least almost equal penetration, particularly with regard to the penetration depth and / or the penetration geometry, of the outer and inner sections into the arable soil, a particularly uniform compaction can be achieved.

[0016] In a further development of the tire according to the invention, the stud element has at least one second outer section which, viewed in the running direction, is designed to extend at least partially in a direction opposite to the first outer section, wherein the second outer section is preferably arranged next to the first outer section, in particular towards the first lateral end of the tread. The second outer section is particularly preferably arranged between the first lateral end of the tread and the first outer section, in particular viewed transversely to the running direction. The stud element is preferably designed to be substantially Y-shaped when viewed transversely to the running direction. In an alternative or additional embodiment, the second outer section is arranged at one end of the first outer section and is designed as an extension of the first outer section extending counter to the running direction.

[0017] In another preferred embodiment of the tire according to the invention, a, in particular outer, side surface of the first outer portion, in particular of the second outer portion, is arranged at least almost in one, in particular vertical, plane with the first lateral end of the tread. In a further preferred embodiment, the tire has at least one sidewall formed radially inwardly from the lateral end, in particular edge, of the tread. The outer side surface of the first and / or second outer portion preferably forms at least almost a plane with the at least one sidewall of the tire. In other words, the, in particular outer, side surface of the first and / or second outer portion is formed planar to the sidewall. By means of such an embodiment, appropriate compaction of the arable soil up to the outermost lateral end, in particular edge, of the cultivation strip can be achieved.

[0018] In another development of the tire according to the invention, the tire comprises at least a first and second circumferential row of studs, each row of studs having a plurality of stud elements, and wherein the stud elements of the first row of studs are preferably arranged at least partially alternating, in particular offset, in the running direction with respect to the stud elements of the second row of studs. Preferably, at least one inner section of the at least one first row of studs faces at least one, in particular laterally opposite, inner section of the at least one second row of studs. The mutually facing inner sections of the two rows of studs are furthermore preferably arranged at least almost directly adjacent to one another.

[0019] Furthermore, a tire is preferred in which at least one row of lugs has between ten and twenty, preferably sixteen or eighteen, lug elements arranged one behind the other. This number of lug elements has a ratio that is particularly favorable for compaction or reconsolidation and / or distribution of the soil.

[0020] In a further preferred embodiment of the tire according to the invention, the tire has a center-to-center distance between the rows of studs, wherein the tire is formed at least virtually free of stud elements, in particular inner sections, along the center-to-center distance. In the inner and / or central region of the tire, a cutout, in particular a ring-shaped, circumferential cutout in the manner of a groove is thus formed. The inner sections of the at least one first row of studs are arranged at a distance from the inner sections of the at least one second row of studs, viewed transversely to the running direction. The center-to-center distance, in particular the distance between the inner sections, is preferably at least approximately one time or twice the width or thickness of an individual inner section.

[0021] In a further development of the tire according to the invention, the first outer section of a first lug element is arranged, as viewed in the running direction, at least partially laterally opposite the inner section of a second lug element, in particular arranged at least partially in front of or behind it. Preferably, an inner section of a second lug element is arranged at a distance behind an inner section of a first lug element, as viewed in the running direction. Likewise, an outer section of the second lug element is preferably arranged at a distance behind an outer section of the first lug element.By arranging the stud elements in this way, profile channels are formed between the inner and / or outer sections arranged one behind the other, which are aligned approximately transversely to the running direction, in particular corresponding to the transverse section, and which are designed to guide the arable soil, in particular the fine soil, which has been at least partially loosened and / or displaced within the working strip, in a defined direction. The arable soil is discharged and / or ejected towards the first lateral end and / or out of the running surface through the profile channels formed between the outer sections. The arable soil is discharged and / or ejected towards the second lateral end and / or out of the running surface through the profile channels formed between the inner sections.Such an embodiment enables a row-related distribution of the arable soil, so that a strip of arable soil intended for the deposition of the material to be distributed is prepared particularly advantageously.

[0022] In a particularly preferred embodiment, the cross-section of the profile channels corresponds at least approximately to the lateral surface of the outer sections. In an alternative but equally preferred embodiment, the cross-section of the profile channels can also be approximately between one and two-thirds of the lateral surface of the outer sections.

[0023] Furthermore, a tire according to the invention is preferred in which a radial height of the outer section, in particular a maximum radial height, starting from a rotational axis of the tire, corresponds at least approximately to a radial height of the inner section. In other words, the circumference of the tire in the region of the outer section, in particular the outer sections, corresponds at least substantially to the circumference of the tire in the region of the inner section, in particular the inner sections. The circumference or the maximum radial height of the tire is thus at least almost constant. The penetration depth of the lug elements into the soil is essentially the same over at least almost all sections, whereby a particularly uniform compaction of the soil is achieved. Starting from the center or the interior of the tread, the tread is designed to slope downwards towards the lateral ends, in particular with a first radius of curvature.The radius of curvature of the tread, preferably oriented transversely to the running direction, corresponds at least approximately to one or a multiple of the total height of the tire. Alternatively or additionally, the radial height of the stud elements is designed to decrease toward the lateral ends, with a second radius of curvature of the stud elements, preferably oriented transversely to the running direction, corresponding at least approximately to twice or a multiple of the first radius of curvature of the tread.

[0024] In another preferred embodiment of the tire according to the invention, the first outer section, in particular the inner section, has at least one, preferably slot-like, recess, wherein the recess is preferably formed at least partially corresponding, in particular at least almost parallel, to the running direction. In particular, a longitudinal direction of the recess is aligned corresponding to a longitudinal direction of the outer section and / or the inner section. The recess is preferably designed to portion and / or position the arable soil, in particular the fine earth, in the region of the outer sections, in particular the inner sections, in a manner suitable for depositing the distribution material. The height or thickness of the recess is preferably approximately one quarter to three quarters of the height of the stud element, in particular of the outer and / or inner section.Furthermore, the width of the recess is preferably approximately one quarter to a maximum of approximately half the width of the outer and / or inner section. The length of the recess corresponds at least approximately to the entire length of the outer and / or inner section. The recess is particularly preferably designed to extend from an end face of the outer and / or inner section to a transition to the transverse section. Alternatively or additionally, a recess is also conceivable in which the length corresponds approximately to half the length of the outer and / or inner section. Furthermore, the recess, in particular viewed transversely to the running direction, is preferably arranged at least almost centrally on the outer and / or inner section, in particular between the respective side surfaces of the outer and / or inner section.

[0025] In a particularly preferred embodiment of the tire according to the invention, the inner sections of two opposing rows of studs are arranged at least partially and at least almost directly adjacent to one another, wherein an intermediate space formed by at least two adjacent inner sections corresponds at least approximately to the at least one, preferably slot-like, recess. The dimensions of the formed intermediate space preferably correspond at least approximately to the dimensions, in particular the depth, width and / or length, of at least one recess arranged on the outer and / or inner sections. The opposite side surfaces of the inner sections are preferably arranged at least partially or alternatively completely adjacent to one another.

[0026] Furthermore, the tire is preferably arranged on a fixed wheel element in the manner of a tire rim. In an alternative embodiment, the at least one tire can also be arranged on a preferably cylindrical wheel element in the manner of a roller. Furthermore, the tire is preferably designed to be pressurized with air from the inside, although a tire made of solid material is also conceivable.

[0027] The object underlying the invention is also achieved with an agricultural sowing and / or soil cultivation implement having at least one divided roller in the manner of a tire packer, wherein the roller comprises at least one tire that is designed according to at least one of the aforementioned embodiments of the tire according to the invention. With regard to the advantages and modifications of the agricultural sowing and / or soil cultivation implement according to the invention, reference is first made to the advantages and modifications of the tire according to the invention.

[0028] In a particularly preferred development of the sowing and / or soil cultivation device according to the invention, the roller comprises at least two tires arranged adjacent to one another with a spacing therebetween, wherein the center distance of at least one tire corresponds at least approximately to the spacing therebetween.

[0029] Furthermore, the sowing and / or soil cultivation device preferably comprises a plurality of coulters engageable with the soil, with at least one coulter being assigned to the roller, in particular to the at least one tire. Particularly preferably, at least two or up to four coulters are assigned to each tire. The at least one coulter is preferably arranged behind the roller, in particular to the at least one tire, as viewed in the direction of travel.

[0030] In another particularly preferred embodiment of the sowing and / or soil tillage implement according to the invention, the at least one recess is configured to correspond to the coulter, in particular at least nearly in alignment, as viewed in the direction of travel. Preferably, within each row of studs, at least one row of consecutively arranged outer and / or inner sections with recesses is formed, with each row of outer and / or inner sections with recesses being assigned a coulter.

[0031] Further details of the invention can be found in the example description and the drawings. The drawings show Fig.1 a variant of an agricultural sowing and / or soil cultivation device in a partial perspective view from the rear; Fig.2 several sowing and / or soil cultivation tools of the Fig.1 shown sowing and / or soil tillage implement in an enlarged plan view; Fig.3A a first embodiment of a tire according to the invention in a view opposite the running direction; Fig.3B the tire from the Fig.3A in a perspective side view; Fig.4A a second embodiment of the tire according to the invention in a view opposite to the running direction; Fig.4B the tire from the Fig.4A in a perspective side view; Fig.5A a third embodiment of the tire according to the invention in a view opposite to the running direction; and Fig.5B the tire from the Fig.5A in a perspective side view.

[0032] A sowing and / or soil cultivation device 10 for spreading, in particular depositing, granular material and / or for cultivating and / or treating arable soil of an agricultural area is described in the Fig.1 shown. The sowing and / or soil tillage implement 10 shown is designed as an agricultural tillage combination and comprises at least one divided roller 20 in the manner of a tire packer and a plurality of distribution material depositing devices 13 arranged behind it in the direction of travel F. The sowing and / or soil tillage implement 10 further comprises at least one central storage container 11 and a distribution material conveying system which has at least one distributor head 12 and is designed to supply the distribution material from the storage container 11 via conveyor lines (not shown) to the respective distribution material depositing devices 13 as required. The distribution material can be designed as seed and / or fertilizer as required. The distribution material depositing device 13 comprises, for example, furrow opening elements 130 which are designed as disc coulters, depth control elements 131 in the manner of a catching and / or pressure roller, and devices for closing the furrow.

[0033] In order to prepare and / or prepare the soil, in particular the seedbed, as evenly as possible for the placement of the material to be distributed, the material depositing devices 13 are assigned to a respective tire 30 arranged in front of them in the direction of travel F, as shown in the Fig.2 can be clearly seen. As shown here by way of example, up to four distribution material depositing devices 13, in particular furrow opening elements 130, can be assigned to each tire, although alternatively more than four assigned distribution material depositing devices 13 are also conceivable. The tires 30 are arranged transversely to the direction of travel F and spaced apart from one another by a distance Z. The tires 30 are further arranged on the sowing and / or soil tillage implement so as to be rotatable about a rotation axis D and are designed to prepare and / or post-treat the arable soil at the appropriate locations, in particular row-related within a tillage strip B, for the deposit of the distribution material, in particular to compact, mix, shred and / or distribute the soil composition or the proportion of fine soil.The illustrated processing strips B represent an area of the cultivated area and / or arable land that is processed and / or driven over by the respective tire 30 during the working process.

[0034] Depending on requirements, such tires 30 can be at least partially inflated with air or, alternatively, made of a solid material, particularly plastic and / or elastomer. Depending on the design variant, the tire 30, which is at least partially elastically constructed, can be connected to the sowing and / or soil cultivation device 10 via a fixed wheel element configured in the manner of a tire rim or a roller, particularly a cylindrical one.

[0035] In order to meet the respective requirements during the cultivation and / or treatment of the arable soil, such a tire 30 has a correspondingly coordinated and / or designed tire tread. The tire 30 comprises, in addition to at least one tread 31 that can be rolled in a, in particular freely selectable, running direction L+, L- of the tire 30, in particular a circumferential tread, as well as a plurality of lug elements 40 that are designed to extend in a, in particular radial direction with a profile height. The lug elements 40 are arranged between two opposite lateral ends 31A, 31B of the tread 31 and at least partially one behind the other in the running direction L+, L-. The lug elements 40 have a transverse section 41 that is designed essentially transversely, in particular obliquely and / or angled, to the running direction L+, L-.

[0036] The Fig.1 and 2The tires shown can be tested in particular according to at least one of the Fig.3A bis 5B shown variants according to the invention. In the case of the Fig.3A und 3B In the first tire variant shown in individual view, the stud elements 40 have a first outer portion 42 facing the first lateral end 31A of the tread 31, which is formed at least in sections, in particular at least almost parallel, to the running direction L+, L-. The first lateral end 31A of the tread 31 and an outer side surface 420 of the first outer portion 42 form a substantially vertical plane. The side surface 420 is thus arranged at least partially planar to a flank 32 formed between the tread 31 and the fixed wheel element.

[0037] Furthermore, the stud elements 40 have at least one inner section 43, which, viewed in the running direction L+, L-, is arranged laterally opposite the first outer section 42, and in particular facing away from the first lateral end 31A of the tread. In this embodiment, the inner section 43 is mirror-symmetrical to the first outer section 42 with respect to a sectional plane 410 oriented at least almost perpendicular to the transverse section 41. Furthermore, the first outer section 42 of a first stud element 40 is arranged, viewed in the running direction L+, L-, at least partially laterally opposite the inner section 43 of at least one other stud element 40, in particular arranged at least partially in front of or behind it.

[0038] As shown in the figures, the tire 30 further comprises at least a first and second circumferential row of lugs R1, R2, each of the rows of lugs R1, R2 comprising a plurality of lug elements 40. Within a row of lugs R1, R2, an inner portion 43 of another lug element 40 is arranged, spaced apart, behind and / or in front of an inner portion 43 of a first lug element 40, as viewed in the running direction L+, L-. Likewise, an outer portion 42 of another lug element 40 is arranged, spaced apart, behind and / or in front of an outer portion 42 of the first lug element 40.The respective spaced inner and / or outer sections 42, 43 thus form profile channels 34A, 34B aligned transversely to the running direction L+, L- and correspondingly to the transverse section 41, which are designed to guide the arable soil, in particular the fine earth, at least partially loosened and / or displaced within the working strip B in a defined direction along the tire profile.

[0039] Furthermore, lug elements 40 of the first lug row R1 are arranged laterally opposite one another and at least partially alternating, in particular offset, in the running direction L+, L-, relative to the lug elements 40 of the second lug row R2. In an alternative embodiment variant (not shown), the lug elements 40 of the different lug rows R1, R2 can also be arranged completely or exactly opposite one another and thus not offset from one another. The first outer sections 42 of the second lug row R2 face a second lateral end 31B of the tread 31, while the inner sections 43 of the second lug row R2 face away from the second lateral end 31B.

[0040] In the Fig.3A und 3B In the embodiment shown, a center-to-center distance 33 is formed along the tread 31 between the opposing rows of studs R1, R2, which is at least virtually free of stud elements 40, in particular inner sections 43. The profile of the tire 30 is formed within this area or distance exclusively by the tread 31. The center-to-center distance 33 of a tire 30 corresponds at least approximately to the intermediate distance Z to a tire 30 arranged adjacent to it. The center-to-center distance 33, in particular the distance between the inner sections 43, further corresponds at least approximately to one or two times the width SB of the inner section 43.

[0041] Both the outer and inner sections 42 of a tire further comprise a, particularly slot-like, recess 45A, 45B. The recesses 45A, 45B are configured to correspond, particularly at least nearly parallel, to the running direction L+, L- and are designed to shape and / or position the soil worked within the working strip B at the locations suitable for depositing the material to be distributed when driving over it. For this purpose, the recesses 45A, 45B are configured to correspond, particularly at least nearly in alignment 450, with the furrow opening element 130, particularly the share, as viewed in the running direction L+, L-, particularly in the direction of travel F. In addition, the recesses 45A, 45B formed on the respective inner and / or outer sections 42, 43 each have a width which corresponds approximately to a quarter of the width SA, SB of the respective outer and / or inner section 42, 43.Alternatively, the width of the recess can also correspond to up to half the width SA, SB of the respective outer and / or inner section 42, 43.

[0042] In addition, a radial height H of the outer sections 42, in particular a maximum, in relation to the axis of rotation D, corresponds at least approximately to a radial height, in particular a maximum, of the inner sections 43. Alternatively, the radial height H of the outer sections 42 can also be designed to slope downwards, at least in sections, towards the lateral end 31A, 31B.

[0043] In this embodiment, the stud elements 40 are designed at least essentially in the manner of a Z when viewed in the running direction L+, L-.

[0044] A second embodiment of the tire 30 according to the invention is shown in the Fig.4A und 4B shown. The geometry of the inner sections 43 differs at least partially from the geometry of the outer sections 42. The opposing inner sections 43 of the respective rows of studs R1, R2 are arranged at least partially and directly adjacent to one another in the central region of the tread 31. An intermediate space 430 formed by at least two adjacent inner sections 43 corresponds, in particular in its dimensions, at least approximately to the slot-like recesses 45A formed on the outer sections 42. Furthermore, up to three material distribution devices 13 can be assigned to the tire 30 shown here, wherein a furrow opening element 130 can be assigned to each of the recesses 45A of both rows of studs R1, R2 and the intermediate spaces 430. The width SB of the inner sections 43 corresponds at least approximately to half the width SA of the outer sections 42.

[0045] In the Fig.5A und 5B a third embodiment of the tire 30 according to the invention is shown. The stud elements 40 each comprise at least one second outer section 44 which, viewed in the running direction L+, L-, is designed to extend at least partially in a direction opposite to the first outer section 42. The second outer section 44 is further arranged next to the first outer section 42 towards the respective lateral end 31A, 31B. In the first row of studs R1, the second outer section 44 is arranged between the first outer section 42 and the first lateral end 31A. In the second row of studs R2, the second outer section 44 is arranged between the first outer section 42 and the second lateral end 31B. In this embodiment, the stud elements 40 are designed at least substantially in the manner of a Y, viewed in the running direction L+, L-.

[0046] Furthermore, the second outer portion 44 of a first stud element 40 is arranged at least partially at a distance laterally opposite and from a first outer portion 42 of another stud element 40, in particular arranged in front of or behind it. The lateral distance between the first and second outer portions 42, 44 corresponds at least approximately to the size of the profile channels 43A, 43B. Bezugszeichenliste
