Strawberry stem holding device

Abstract

In a strawberry stem holding device according to the present invention, because a first holder (40a) and a second holder (40b) are away from a bed (20) when a ball screw (34) rotates forward due to the driving force of a through-motor (32) during harvesting of strawberries, only matured strawberries (14) distinguished from unripe strawberries (14) so as not to overlap each other can be rapidly harvested by a harvester from strawberry stems (12) which are held one-by-one respectively by a plurality of holding grooves (44), and thus there is an effect of improving a yield.

Description

Strawberry stem holder

[0001] The present invention relates to a strawberry stem support device, and more particularly, to a strawberry stem support device in which strawberry stem supports having grooves formed at regular intervals with a width corresponding to the length of the bed are installed on the lower side of strawberry seedlings grown in the bed and are capable of moving forward or backward.

[0002] Strawberry seedlings grown in beds usually produce primary flower stalks, grow for several days, and then strawberry flowers bloom at the tip of the first node of the stem, producing the first strawberry fruit.

[0003] As soon as the first strawberry fruit is formed, 2-3 second flower stalks are created and grow for several days, then strawberry flowers bloom at the end of the first node and second strawberry fruit is formed.

[0004] As the second strawberry fruit is formed, 2-3 tertiary flower stalks are formed and grow for several days, then strawberry flowers bloom on the first node and the third strawberry fruit is formed.

[0005] As the third strawberry fruit is formed, 2 to 3 fourth flower stalks are produced, and this process is repeated until the eighth stage.

[0006] At this time, the first strawberry stem that has developed is the shortest, and the strawberry stems sequentially grow longer and irregularly, so that most of the strawberry fruits are covered as ripe and unripe strawberries grow in a chaotic manner, as shown in Fig. 1.

[0007] Therefore, the strawberry harvesters proposed to date have very low harvest rates and are not yet commercially viable.

[0008] The purpose of the present invention is to provide a strawberry stem support device that can increase the yield of ripe strawberries by individually supporting strawberry stems that have developed from strawberry seedlings in a plurality of support grooves on a support side, and then moving the support forward to distinguish ripe strawberries from unripe strawberries so that they do not overlap.

[0009] According to an embodiment of the present invention for solving the above technical problem, a strawberry stem support device comprises: a pair of frames installed at the front and rear sides of a bed for cultivating strawberry seedlings; a pair of through-motors each installed at the center of the pair of frames; a pair of ball screws each installed in the pair of through-motors; a first supporter disposed on the left side of the bed and connected to the left side of the pair of ball screws via a pair of first screw nuts so as to widen or narrow a gap therebetween from the bed; and a second supporter disposed on the right side of the bed and connected to the right side of the pair of ball screws via a pair of second screw nuts so as to widen or narrow a gap therebetween from the bed.

[0010] As another embodiment of the present invention, the pair of frames are characterized in that they are installed horizontally on the front and rear sides of the bed, respectively.

[0011] As another embodiment of the present invention, the pair of frames are characterized in that they are installed at the same intermediate height with respect to the front and rear sides of the bed.

[0012] As another embodiment of the present invention, the pair of ball screws is characterized in that they rotate at the same speed in the same forward or reverse direction when the pair of through motors are driven.

[0013] As another embodiment of the present invention, the pair of first screw nuts are respectively installed on the lower surface of both ends of the first holder.

[0014] As another embodiment of the present invention, the pair of second screw nuts are respectively installed on the lower surface of both ends of the second holder.

[0015] In another embodiment of the present invention, the pair of first screw nuts are each installed at the same distance from the left side of the bed with respect to the lower surface of both ends of the first stand, and the pair of second screw nuts are each installed at the same distance from the right side of the bed with respect to the lower surface of both ends of the second stand.

[0016] As another embodiment of the present invention, the pair of first screw nuts and the pair of second screw nuts are installed to be spaced apart at equal intervals with the bed interposed therebetween.

[0017] In another embodiment of the present invention, the first holder and the second holder are characterized in that each of the first holder and the second holder comprises a flat plate portion; and a plurality of holding grooves are continuously formed at a predetermined interval along the length direction of the flat plate portion with respect to the outer end of the flat plate portion so that strawberry stems generated from the strawberry seedlings are held individually one by one.

[0018] As another embodiment of the present invention, the plurality of the above-described mounting grooves are characterized in that they are alternately formed in a large V shape and a small V shape along the longitudinal direction of the flat plate portion.

[0019] The first and second holders of the strawberry stem holder according to the present invention have a gap from the bed when the ball screw is rotated in the forward direction by the driving force of the penetrating motor during strawberry harvesting, so that among the strawberry stems individually held by the plurality of holding grooves, only ripe strawberries, which are distinguished from unripe strawberries, can be quickly harvested by the harvester without overlapping each other, thereby increasing the harvest rate.

[0038] Hereinafter, to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the attached drawings, FIGS. 2 to 4. The embodiments of the present invention may be modified in various ways, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. It should be noted that in each drawing, identical components are sometimes depicted with the same reference numerals. Detailed descriptions of well-known functions and components that may unnecessarily obscure the gist of the present invention are omitted.

[0039] A strawberry stem support device according to an embodiment of the present invention comprises a pair of frames (30) installed on a bed (20) for cultivating strawberry seedlings (10), a pair of through-motors (32), a pair of ball screws (34), a pair of first screw nuts (36a), a pair of second screw nuts (36b), a first support (40a), and a second support (40b).

[0040] That is, the above pair of frames (30) are installed horizontally at the same intermediate height for the front and rear sides of the bed (20), respectively, and serve to hold the first holder (40a) and the second holder (40b) so that they float on the left and right sides of the bed (20) via a pair of through motors (32), a pair of ball screws (34), a pair of first screw nuts (36a), and a pair of second screw nuts (36b).

[0041] The above pair of through-motors (32) are each installed in the center of the lower surface of a pair of frames (30), and serve to drive a pair of ball screws (34) to rotate forward or reverse.

[0042] The above pair of ball screws (34) are arranged horizontally symmetrically left and right through the center of the through-motor (32), and rotate at the same speed in the same forward or reverse direction when the pair of through-motors (32) are driven.

[0043] At this time, it is preferable that a pair of ball screws (34) are formed in a left-hand screw shape on the right side while the left side is formed in a right-hand screw shape with the through motor (32) in between.

[0044] That is, the right-hand screw type and the left-hand screw type of a pair of ball screws (34) serve to cause the first screw nut (36a) and the second screw nut (36b) screwed on both sides of the ball screw (34) with the through motor (32) therebetween to increase the gap from the simultaneous through motor (32) when rotating in the forward direction, and conversely, when rotating in the reverse direction, the first screw nut (36a) and the second screw nut (36b) screwed on both sides of the ball screw (34) with the through motor (32) therebetween to decrease the gap toward the simultaneous through motor (32).

[0045] It is preferable that the above pair of first screw nuts (36a) are each installed at equal intervals from the left side of the bed (20) with respect to the lower surface of both ends of the first support (40a).

[0046] It is preferable that the above pair of second screw nuts (36b) are each installed at equal intervals from the right side of the bed (20) with respect to the lower surface of both ends of the second support (40b).

[0047] At this time, it is preferable that the pair of first screw nuts (36a) and the pair of second screw nuts (36b) are installed at equal intervals with the bed (20) in between.

[0048] The above first support (40a) is arranged on the left side of the bed (20) and is connected to the left side of a pair of ball screws (34) and a pair of first screw nuts (36a) respectively so that the gap between them is widened or narrowed from the bed (20), and serves to individually support a plurality of strawberry stems (12) that extend from the bed (20) to the left among a plurality of strawberry stems (12) that originate from strawberry seedlings (10).

[0049] The second support (40b) is arranged on the right side of the bed (20) and is connected to the right side of a pair of ball screws (34) and a pair of second screw nuts (36b) respectively so that the gap between them is widened or narrowed from the bed (20), and serves to individually support a plurality of strawberry stems (12) that extend from the bed (20) to the right among a plurality of strawberry stems (12) that originate from the strawberry seedlings (10).

[0050] At this time, the first holder (40a) and the second holder (40b) are each formed with a flat plate portion (42) of a thin plate; a plurality of holding grooves (44) are continuously formed at regular intervals along the length direction of the flat plate portion (42) with respect to the outer end of the flat plate portion (42) so that strawberry stems (12) generated from strawberry seedlings (10) are individually held one by one, and it is preferable that the plurality of holding grooves (44) are alternately formed in a large V shape and a small V shape along the length direction of the flat plate portion (42).

[0051] In this way, since the first holder (40a) and the second holder (40b) of the present invention are spaced apart from the bed (20) when the ball screw (34) is rotated in the forward direction by the driving force of the penetrating motor (32) during strawberry harvesting, only ripe strawberries (14) that are distinguished from unripe strawberries (14) among the strawberry stems (12) individually mounted by the plurality of mounting grooves (44) without overlapping each other can be quickly harvested by the harvester.

[0052] That is, among the strawberry stems (12) individually supported by a plurality of support grooves (44), the first support (40a) and the second support (40b) are heavier than the unripe strawberries (14), so they hang down from the first support (40a) and the second support (40b), thereby increasing the harvest rate so that they can be harvested quickly by the harvester.

[0053] Meanwhile, the present invention is not limited to the above-described embodiments, but can be implemented by modifying and changing the same within the scope that does not deviate from the gist of the present invention, and the technical ideas to which such modifications and changes are applied should also be considered to fall within the scope of the following patent claims.
