Description

Technology Field

[0001] The present invention relates to a grass pickup device, and more specifically, to a grass pickup device configured such that the pickup spring rotates around a rotation axis rather than rotating in a cam track manner to increase the rotational speed, and the pickup spring is fixed at a certain angle inclined with respect to the center of rotation so that the grass is picked up in a bouncing manner rather than a pulling manner, thereby enabling the grass to be picked up with stones or soil separated and removed.

[0002] The present invention relates to a grass pickup device that does not apply a cam track method, thereby simplifying the structure and improving durability.

[0003] The present invention relates to a forage pickup device that allows for easy replacement of parts such as pickup springs, enabling the user to repair it immediately on-site and improve productivity.

[0004] The present invention relates to a grass pickup device that allows for the efficient separation of stones or soil contained in grass by sequentially picking up grass during rotation, as the pickup springs are not arranged in a straight line.

[0005] The present invention relates to a grass pickup device in which the pickup spring is applied in a straight form without bends so that durability can be further improved.

[0006] The present invention relates to a grass pickup device configured such that a transfer guide, which guides the picked-up grass to the rear when the pickup spring rotates, is suspended from the upper part, thereby significantly reducing the possibility of damage.

[0007] The present invention relates to a grass pickup device in which a transfer guide is formed in a bent shape so that the transfer of picked-up grass and the separation of the grass and the pickup spring can be performed sequentially.

[0008] The present invention relates to a grass picking device that is equipped with a tilting unit at one end in the width direction to allow for movement within a certain range in the up / down direction, thereby preventing impact during picking operations in places with many curves and enabling the picking of grass without omission. Background Technology

[0009] Hay (harvested rice straw or mowed pasture) has recently been utilized as feed for livestock, so a hay pickup device is installed on a baler to collect the hay, and the collected hay is supplied to the baler's chamber to compress, bind, and package the hay.

[0010] These balers are primarily used in rice paddies and pastures by being mounted on the rear of a tractor, and include round balers or square balers.

[0011] And the baler is a collection unit, i.e., a pickup device, driven by power support from a trailer, and is composed of a frame that is installed to be movable on the vehicle body by a lifting unit, a pickup unit that is rotatably installed on the frame and has a pickup spring that is pulled out and retracted into the rear and bottom portions when rotated, and strip-shaped unit covers installed on the frame and installed between each pickup spring of the pickup unit.

[0012] For example, Korean Published Patent No. 10-2012-0087708 discloses a pickup device for a baler having a structure as shown in Fig. 1, Korean Published Patent No. 10-2013-0138600 discloses a pickup device for a baler having a structure as shown in Fig. 2, Korean Registered Patent No. 10-2043257 discloses a baler pickup structure having a structure as shown in Fig. 3, and Korean Registered Patent No. 10-2046050 discloses a baler hay pickup device having a structure as shown in Fig. 4.

[0013] However, the prior art disclosed in FIGS. 1 to 4 has the problem that the unit covers are made in an elliptical shape and easily deform or break when subjected to external impact during fodder pickup.

[0014] In addition, deformation and damage to the unit cover are undesirable as they cause interference with the pickup spring, leading to the pickup spring's failure. Consequently, maintenance and repairs must be handled with the assistance of a technician, which results in issues of time and cost.

[0015] And the prior art disclosed in FIGS. 1 to 3 adopts a cam track rotation method, so the rotation speed of the pickup spring is slow and all are arranged in the same straight line, so it operates in a way that scoops up grass, and soil or stones are easily drawn in.

[0016] Therefore, when picking up pasture, stones or soil are picked up along with it, causing damage, and since the packaged pasture contains a large amount of stones or soil, it is undesirable as it causes livestock to be exposed to viruses and pathogens.

[0017] In addition, the cam track rotation method has the problem of being inconvenient to maintain and manage because its complex configuration and poor durability result in a short parts replacement cycle.

[0018] In addition, there is a problem of reduced productivity because users have difficulty repairing simple damage, such as the bending of the pickup spring, on their own.

[0019] In addition, the prior art illustrated in FIGS. 1 to 4 has a problem in that the end of the pickup spring is bent in order to pull up the grass as the rotation speed of the pickup spring is slow, so bending due to external impact occurs frequently.

[0020] Furthermore, since the pickup device is fixed on both sides, there is a problem where pickup is not smooth when working in the undulating Korean terrain, such as picking up only a portion of the grass before proceeding. The problem to be solved

[0021] The objective of the present invention is to solve the problems of the prior art as described above. The present invention relates to a grass pickup device, wherein the pickup spring is configured to rotate around a rotation axis rather than rotating in a cam track manner to increase the rotational speed, and the pickup spring is fixed at a certain angle inclined with respect to the center of rotation so that the grass is picked up in a bouncing manner rather than a pulling manner, thereby allowing only light grass from which stones or soil have been separated and viruses and germs removed to be picked up.

[0022] Another objective of the present invention is to provide a pasture pickup device that does not apply a cam track method, thereby simplifying the structure and improving durability.

[0023] Another objective of the present invention is to provide a forage pickup device that allows for easy replacement of parts such as pickup springs, enabling the user to repair it immediately on-site and improve productivity.

[0024] Another objective of the present invention is to provide a grass pickup device that can efficiently separate stones or soil contained in grass by sequentially picking up grass when rotating, by dividing the pickup springs into three parts and placing them at different positions rather than arranging them in a straight line.

[0025] Another objective of the present invention is to provide a grass pickup device in which the pickup spring is applied in a straight form without bends so that durability can be further improved.

[0026] Another objective of the present invention is to provide a grass pickup device in which a transfer guide that guides the picked-up grass to the rear when the pickup spring rotates is configured to be suspended from the upper part, thereby significantly reducing the possibility of damage.

[0027] Another objective of the present invention is to provide a grass pickup device in which the transfer guide is formed in a bent shape so that the transfer of the picked-up grass and the separation of the grass and the pickup spring can be performed sequentially.

[0028] Another objective of the present invention is to provide a grass picking device that can prevent impact during picking operations in areas with many curves by providing a tilting unit at one end in the width direction to allow movement within a certain range in the up / down direction, and can pick up grass without omission. means of solving the problem

[0029] The grass pickup device according to the present invention is characterized by comprising: a pickup unit that picks up grass while rotating by being axially coupled to a rotating shaft that rotates by receiving rotational force from an external source; a pair of support plates located on both sides of the rotating shaft to support rotation; a support frame located between the pair of support plates to support maintaining a certain distance; a transport guide coupled to the support frame and placed on the upper side of the pickup unit to guide the transport direction of the picked grass; and a load support plate connected to an agricultural machine in a state coupled to the support frame so that the pickup unit is connected to the agricultural machine to support the load.

[0030] One side of the load support plate is characterized by having a tilting unit that allows the support plate to move up and down within a certain height range.

[0031] The above pickup unit is characterized by comprising a pickup body that rotates in conjunction with the rotation axis, a plurality of pickup springs fixed to protrude outward from the pickup body and pick up grass when the rotation axis rotates, and a protective cover positioned between the pickup springs to shield the opening of the pickup body.

[0032] The above pickup spring is characterized by rotating around the rotation axis as the rotation center.

[0033] The above pickup spring is characterized by being positioned at a certain angle of inclination with respect to a virtual straight line passing through the center of the rotation axis.

[0034] The above pickup springs are characterized by being spaced at equal intervals in the circumferential direction of the pickup body and positioned at different locations in the width direction.

[0035] The above transfer guide is configured in the form of a bent plate and is characterized by comprising a pickup part located lower than the end of the pickup spring when the pickup spring rotates, and a guide part located higher than the end of the pickup spring. Effects of the invention

[0036] The grass pickup device according to the present invention is configured such that the pickup spring is configured to rotate around a rotation axis rather than rotating in a cam track manner to increase the rotational speed, and the pickup spring is fixed at a certain angle of inclination with respect to the center of rotation so that the grass is picked up in a bouncing manner rather than a pulling manner, thereby enabling the pickup of grass from which stones or soil have been separated and removed.

[0037] Therefore, by not applying the cam track method, the structure is simple and durability can be improved.

[0038] In addition, parts such as pickup springs are easy to replace, resulting in lower maintenance and management costs and improved productivity.

[0039] In addition, since the pickup springs are not arranged in a straight line, stones or soil contained in the grass can be efficiently separated by picking up the grass sequentially during rotation.

[0040] In addition, the pickup spring is applied in a straight form without bends, which can further improve durability.

[0041] In addition, the transfer guide that guides the picked-up grass to the rear when the pickup spring rotates is configured to be suspended from the top, which can significantly reduce the possibility of damage.

[0042] In addition, the transfer guide is formed in a bent shape, so the transfer of the picked-up grass and the separation of the grass and the pickup spring can be performed sequentially.

[0043] In addition, by equipping a tilting unit on one end in the width direction to allow for movement within a certain range in the up / down direction, it is possible to prevent impact during pickup operations in areas with many curves, and there is an advantage of being able to pick up grass without missing any.

[0045] The configuration of the grass pickup device (100) according to the present invention will be explained below with reference to the attached FIGS. 5 and 6.

[0046] FIG. 5 shows a partial enlarged photograph showing a state in which a conveying guide (150), which is a component of the grass pickup device (100) according to the present invention, is attached, and FIG. 6 shows an overall photograph showing the exterior of the grass pickup device (100) according to the present invention.

[0047] Prior to this, terms and words used in this specification and claims shall not be interpreted in their ordinary and dictionary meanings, but must be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor may appropriately define the concept of the terms to best describe his invention.

[0048] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely preferred embodiments of the present invention and do not represent all technical concepts of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0049] As shown in the attached drawing, the pasture pickup device (100) according to the present invention is installed on agricultural machinery such as a baler to pick up harvested rice straw or mowed pasture, and operates to lift by rotating a plurality of pickup springs (124) clockwise.

[0050] To this end, the above-described grass pickup device (100) comprises a pickup unit (120) that rotates by being coupled to a rotating shaft (110) that receives rotational force from an external source and picks up grass while rotating; a pair of support plates (130) located on both sides of the rotating shaft (110) to support the rotating shaft (110) so that it can rotate; a support frame (140) located between the pair of support plates (130) to support it while maintaining a certain distance; a transport guide (150) coupled to the support frame (140) and placed on the upper side of the pickup unit (120) to guide the transport direction of the picked-up grass; and a load support plate (160) that is coupled to the support frame (140) and connected to an agricultural machine so that the pickup unit (120) is supported by the load of the agricultural machine.

[0051] The above-mentioned rotating shaft (110) is connected to a power transmission member such as an agricultural machine and a chain to receive rotational power and rotate. In the past, a cam track rotation method was applied, and as the pickup spring (124) rotated in an elliptical path, the speed was slow, and the numerous bearings rotating along the cam track were subjected to impact, causing frequent breakdowns. Consequently, there were many problems, such as frequent breakdowns occurring when the ground became muddy during rain. However, in the present invention, the above-mentioned rotating shaft (110) has bearings applied to both sides so that it rotates in place. As a result of the rotation of the above-mentioned rotating shaft (110), the pickup spring (124) can rotate in a circle around the rotating shaft (110).

[0052] The above-mentioned rotating shaft (110) is arranged extending from the left to the right side of the grass pickup device (100) and simultaneously performs the function of supporting the pickup unit (120) so that it can rotate.

[0053] That is, the above pickup unit (120) comprises a pickup body (122) that rotates in conjunction with a rotation axis (110), a plurality of pickup springs (124) fixed to protrude outward from the pickup body (122) to pick up grass when the rotation axis (110) rotates, and a protective cover (126) positioned between the pickup springs (124) to shield the opening (123) of the pickup body (122).

[0054] The above pickup body (122) has radially formed openings (see reference numeral 123 in FIG. 7) and is coupled to and works in conjunction with a rotation axis (110).

[0055] The above openings (123) are provided in multiple locations as they are open to allow looking into the interior of the pickup body (122) and are arranged radially at equal intervals on the outer circumference of the pickup body (122). In an embodiment of the present invention, four openings (123) are formed on the left and right sides of the pickup body (122) and seven are formed in the central part, and adjacent openings (123) are arranged at different positions when viewed in the longitudinal direction of the pickup body (122) so as not to cause a decrease in durability.

[0056] And when looking into the opening (123), the rotation axis (110) can be visually confirmed, and the opening (123) is shielded by a protective cover (126) that can be optionally attached or detached, thereby restricting the entry of foreign matter.

[0057] The above pickup spring (124) is configured by winding a metal rod having a predetermined diameter so that both ends protrude in the same direction, and is provided with an elastic part (125) having elastic restoring force in the center, and is fixed by being fastened to the pickup body (122) with a fastening member such as a bolt.

[0058] The elastic part (125) of the above pickup spring (124) is located between the protective cover (126), and the part where the elastic part (125) is connected is located closer to the rotation axis (110) than the protective cover (126).

[0059] Accordingly, when the elastic part (125) of the pickup spring (124) is connected to the pickup body (122), the end is in a state where it protrudes outward as shown in the drawing, but the elastic part (125) is received between the protective cover (126) and can be protected from external impact caused by gravel, etc.

[0060] And the above pickup spring (124) is elastically supported by the elastic part (125) so that it can lift the grass mixed with gravel and soil by bouncing it out. (For example, heavy materials are bounced away, and only light grass and straw are transported.)

[0061] Support plates (130) are provided on both sides of the pickup body (122). The support plates (130) support the load of the rotation axis (110) and the pickup unit (120) while allowing the pickup unit (120) to rotate. They are made of metal plates, and a coupling part (132) is formed on the upper part so that the grass pickup device (100) can be coupled to an agricultural machine.

[0062] Therefore, when the connecting part (132) is connected to one side of the agricultural machine, the pasture pickup device (100) is supported by the load on the agricultural machine and can move together with the agricultural machine when it moves, and the rotational power transmitted from the agricultural machine rotates the rotating shaft (110) to enable pasture pickup.

[0063] The support frame (140) is configured to be installed horizontally from the rear of the pickup body (122), and a plurality of transfer guides (150) are spaced apart and installed on the upper end of the support frame (140), and support plates (130) are firmly connected to both ends.

[0064] Therefore, when the support frame (140) and the support plate (130) are combined, approximately " It has a shape, and a pickup unit (120) is rotatably installed on the inside.

[0065] The above transfer guide (150) is formed by bending a strip-shaped plate, with the upper surface bent at different angles, and is fixed so as not to interfere with the pickup spring (124).

[0066] In FIG. 6, the transfer guide (150) is shown removed for convenience of explanation, and the transfer guide (150) shown in FIG. 5 is attached to each protruding part of the support frame (140).

[0067] The support frame (140) and the support plate (130) are connected by a load support plate (160). The load support plate (160) has the aforementioned connecting part (132) formed thereon and is provided with one on each side of the grass pickup device (100).

[0068] More specifically, among the pair of load support plates (160), the load support plate (160) located on the right side as seen in FIG. 6 is firmly connected to the support plate (130), and the load support plate (160) located on the left side is connected so as to be able to move within a certain height range relative to the support plate (130).

[0069] And for this function, the load support plate (160) on the left is equipped with a tilting unit (see reference numeral 170 in FIG. 11).

[0070] The above tilting unit (170) will be described in detail below, and the detailed configuration of the pickup unit (120) will be described below with reference to the attached FIGS. 7 to 10.

[0071] FIG. 7 is a partial enlarged photograph showing the protective cover (126), which is a component of the grass pickup device (100) according to the present invention, in an open state; FIG. 8 is a partial enlarged photograph showing the operation of the protective cover (126), which is a component of the grass pickup device (100) according to the present invention; FIG. 9 is a cross-sectional view showing the mounting structure of the pickup spring (124), which is a component of the grass pickup device (100) according to the present invention; and FIG. 10 is a cross-sectional view showing the operation of the pickup spring (124) and the transfer guide (150), which are components of the grass pickup device (100) according to the present invention.

[0072] As described above, the pickup spring (124) rotates around the rotation axis (110) as the rotation center, is spaced at equal intervals in the circumferential direction of the pickup body (122), and is positioned at different locations in the width direction as shown in FIG. 6.

[0073] This is to enable gravel or soil to be removed more easily and to increase the durability of the pickup spring (124) by operating the pickup spring (124) by dividing the number of contacts when the pickup spring (124) rotates to pick up grass.

[0074] Meanwhile, the pickup spring (124) is installed in a shape inclined at a certain angle ("A" in FIG. 9) with respect to a virtual straight line passing through the center of the rotation axis (110) as shown in FIG. 9.

[0075] Therefore, when the above pickup spring (124) is inserted into the lower side of the grass and rotates, the grass is not lifted upward but pushed upward to the left, and since the movement speed of the pickup spring (124) is fast, gravel or soil can be separated from the grass as if shaken off.

[0076] In addition, the above pickup spring (124) is installed in a shape inclined by "A" so that even if it comes into contact with the ground during operation, it does not receive a strong impact and can be bent and restored to its original shape by elastic restoring force.

[0077] As shown in FIGS. 9 and 10, the above transfer guide (150) is divided into a portion that exposes the end of the pickup spring (124) when the pickup spring (124) passes sideways and a portion that hides it downwards.

[0078] That is, the above transfer guide (150) is configured in the form of a bent plate, and the left side is configured to include a pickup part (152) located lower than the end of the pickup spring (124) when the pickup spring (124) rotates, and a guide part (154) located higher than the end of the pickup spring (124).

[0079] Accordingly, the pickup section (152) guides the pickup spring (124) to be exposed upward so that the grass picked up by the pickup spring (124) can be transported backward, and the guide section (154) is bent to have a downward slope compared to the pickup section (152) so that the pickup spring (124) can be separated from the grass transported backward by a certain distance.

[0080] Accordingly, when the pickup spring (124) is positioned in the pickup section (152), it is in the state shown in FIG. 9. When the rotation shaft (110) rotates further and the pickup spring (124) approaches the transfer guide (150) as shown in FIG. 10, the position of the end of the pickup spring (124) gradually lowers and is positioned below the guide section (154).

[0081] The operation of the tilting unit (170) will be explained below with reference to the attached FIG. 11.

[0082] FIG. 11 shows a side view of the operation of a tilting unit (170), which is a component of the grass pickup device (100) according to the present invention.

[0083] As shown in the drawing, the tilting unit (170) is configured to allow the support plate (130) to move up and down within a certain height range relative to the load support plate (160).

[0084] That is, the above tilting unit (170) acts to enable tilting with respect to one of the support plates (130) located on both sides of the pickup body (122). In an embodiment of the present invention, the tilting unit (170) is applied only to the left side, and is illustrated in detail as in FIG. 11.

[0085] More specifically, the tilting unit (170) is configured to include an anti-detachment projection (172) protruding from the pickup body (122) and a tilting hole (174) drilled in the load support plate (160) to have a size larger than the anti-detachment projection (172).

[0086] The above tilting hole (174) has a width slightly larger than the diameter of the above anti-detachment projection (172) and is drilled long in the vertical direction.

[0087] Accordingly, when the anti-detachment projection (172) is received in the tilting hole (174), the pickup unit (120) moves downward due to its own weight, and when the grass pickup device (100) encounters an uneven surface while moving, the anti-detachment projection (172) moves upward inside the tilting hole (174) to become a state as shown in FIG. 11, thereby enabling the grass to be picked up without omission.

[0088] The scope of the present invention is not limited to the embodiments exemplified above, and within such technical scope, many other variations based on the present invention will be possible to those skilled in the art.

[0089] For example, in an embodiment of the present invention, the tilting unit (170) is applied to only one of the pair of load-bearing plates (160), but it is obvious that it can be applied to both sides.

[0090] In addition, in the embodiment of the present invention, the pickup springs (124) are arranged in a straight line in a certain number along the length direction of the support frame (140) and are arranged in a stepped shape overall, but it is obvious that the arrangement shape can be changed in various ways as long as all the pickup springs (124) are not set up in a straight line.
