Description

  In order to increase the efficiency of manure management work in an orchard, the present invention is intended for fruit trees comprising trees such as pears, loquats, peaches, apples and vines such as branches or straws, kiwifruits, etc. composed of metal pipes and wires. Grown along the shelf. The fruits of these fruit trees become bloated at the same time as the typhoon hits, and the harvest season begins. For this reason, the fruit which grew greatly relates to what tries to suppress the typhoon damage which falls and shakes up and down by a strong wind, and reduces a commercial value remarkably.

  Conventionally, between the fruit cultivated by hanging on the branches or vines of fruit trees that are cultivated by attracting and stretching in an approximately horizontal direction at an appropriate position of about 1.5 to 2.0 meters above the ground, and the surface of the cultivated land To secure the space required for smooth manure management work (cultivation work by tractor and spraying of agricultural chemicals by speed sprayer or movement of transport vehicles such as self-propelled weeders and fertilizers or harvested fruits) There is a fruit shelf formed for this purpose. (Patent Documents 1 and 2)

[Technology of Patent Document 1]
Patent Document 1 discloses a technique in which a wire is placed on the top of a fixed support erected on an anchor embedded in the ground, and these “wires are laid in a grid pattern at an arbitrary height from the ground” Is described.

[Technology of Patent Document 2]
Patent Document 2 describes a technique of “cultivating fruit tree branches or vines suspended on a fruit tree shelf formed of wires supported by anchor poles”.

[Problems of Patent Document 1]
A large tension always acts on the wire of the fruit shelf formed by the side pillars and corner pillars that are erected so as to surround the orchard and the middle pillar that prevents the wire from hanging down.
In addition, the weight of vines such as pears, peaches, branches and vines, kiwifruits, etc. supported by these wires, and the pears, peaches, etc., branches and cocoons, kiwifruits, etc. The fruit weight is also added. For this reason, a large tension is applied to the wire for a long time, and the wire is stretched loosely due to metal fatigue and is laid loosely. For this reason, the fruit tree and the fruit which grew on the branch or the vine supported by these wires have a fear of fruit fall when receiving a strong wind. (Problem 1)

[Problems of Patent Document 2]
Wires depending on the mass of fruit tree branches or vines and fruits located near the midpoint between the fruit tree (2) and the strut (5) and near the midpoint between the fruit tree (2) and the strut (11) as seen in FIG. (8) has the largest amount of drooping. For this reason, the fruit tree shelf located near these intermediate points has a hammock shape. Fruits suspended in fruit branches or vines in such a state are exposed to a dangerous state in which they are greatly moved up and down when dropped by a strong wind such as a typhoon. (Problem 2)

[Problems of Patent Document 1 and Patent Document 2]
In addition, in order to avoid the dangerous state as described above, there is an option to increase the struts in order to shorten the distance between the struts. However, these anchors are embedded by digging up the ground surface and burying solid members that serve as anchors. When the fixed support | pillar based on this is added, these support | pillars will become an obstruction, the work space for the above-mentioned cultivation management will run short, and the subject that obstructs the cultivation management will generate | occur | produce. (Problem 3)

  In view of (Problem 1), there is a need for means that compensates for the slack of the wires constituting the fruit shelf. (Needs 1)

  In view of (Problem 2), there is a means for suppressing drooping due to the mass of fruit branches or vines and fruits located between the pillars and the vertical movement of these fruit tree branches or vines and fruits due to strong winds. It has been demanded. (Needs 2)

  Based on (Problem 3), if a typhoon approaches and damage to the fruit tree shelf is expected, it can be dealt with promptly, and when the typhoon warning forecast is canceled, a working space for fertilizer management will be secured immediately. There is a need for a strut that can be easily and quickly removed. (Needs 3)

"Configuration of auxiliary support (P)"
As seen in FIGS. 1 and 2a, the branches of the fruit tree (ft) through a protective material (pt) interposed inside the receiving part (3) provided in the upper end part (10) of the inner pipe (1). (B) is confined.

  Further, as shown in FIGS. 1 and 2a, the length of the auxiliary strut (P) in the axial direction is kept within a predetermined range by the holding portion (5) disposed at the upper end (20) of the outer pipe (2). Can be adjusted freely.

  As shown in FIGS. 2a and 2b, the holding portion (5) is formed with a notch (58) directed downward from the upper end portion (20) of the outer pipe (2).

As shown in FIGS. 2a and 2b, a band (59) is attached to the outside of the upper end (20) of the outer pipe (2) so as to surround the entire periphery except for a part of the notch (58). The Seat surfaces (54a) and (54b) having through holes (55a) and (55b) through which the bolts (54) are inserted are formed by bending the end surface of the band (59) outward, and these seat surfaces (54a) And the contact part (57) with the nut (53) which contacts (54b) is formed. The nut (53) is fixedly welded to the seating surface (54a).
Further, a predetermined portion facing outward from the abutting portion (57) formed on the opposing portion of the bolt (53) is bent at a right angle with respect to the axis formed by the bolt (54) to form the lever (56). .

  Further, as shown in FIGS. 1 and 2a, the spiral pile (4) is fixed to the lower end (21) of the outer pipe (2).

  As seen in FIG. 3, the receiving portion (3) is fixed to the upper end portion (10) of the inner pipe (1).

  A protective material (Pt) that is rich in flexibility and prevents damage to the skin of the branch (B) is disposed inside the receiving portion (3), and is confined and protected so as to wrap the branch (B).

  Further, as shown in FIG. 3, the support inserted into the pin hole of the bifurcated support portion formed on the distal end side of the support arm (30) fixed to the upper end portion (10) of the inner pipe (1). The movable arms (31a) and (31b) are mounted so as to open and close the opening (37) of the receiving portion (3) supported by the pin (32a) and the support pin (32b).

  A helical pipe (36) having a helical male screw (35) is rotatably mounted on the outer peripheral side near the upper end (10) of the inner pipe (1).

  A helical female screw (38) having a helical female screw on the inner periphery and formed in a nut shape is externally fitted to the helical pipe (36) so as to be movable in the axial direction. .

  The inner pipe (1) is gripped near the lower end so as to be gripped when the helical male screw (35) extending from the upper end (10) to the lower side is appropriately rotated. A part (50) is formed.

  A retaining ring (51) is fixed to the inner pipe (1) so as to prevent the gripping part (50) from moving downward.

  Further, the pin holes on the helical female screw (38) and the link holes (39a) and (39b) respectively inserted into the pin holes on the link (33) are connected.

  And the pin hole which exists in the other end part of the link (33a) and (33ba) arrange | positioned so that it may pass between the crotch of the support arm (30) formed in a bifurcated shape, and the pin hole which exists in a link (33a) and (33ba) The spiral nut-shaped helical female screw (38) is connected by the link pins (39a) and (39b) respectively inserted into the spiral nuts. Accordingly, when the gripping portion (50) is rotated to open and close the opening (37), the rotation of the helical female screw (38) is prevented, and the helical female screw (38) is prevented from being rotated by the gripping portion (50). It moves according to the rotation direction and the rotation amount.

  As shown in FIG. 4, a protective material (Pt) is attached around the branch (B) to prevent the fruit tree branch (B) from being damaged by direct contact with the receiving part (3). Damage to the branch (B) is prevented.

  FIG. 5 shows the positional relationship of the constituent members accompanying the movement of each member in a state where a relatively small branch (B) is captured and bound to the receiving portion (3).

  What is seen in FIG. 6 shows a state in which the auxiliary strut (P) has been withdrawn, and a manure management space (43) found in the original orchard has been formed.

  What is seen in FIG. 7 is that a support column (64) (see FIG. 1) used in a conventional fruit tree shelf is replaced with an auxiliary support column (P) of the present embodiment. It is the Example figure which supported the intersection (Cs), such as the trunk line (60) which is a structural member of this, or an X-axis branch line (62), and a Y-axis branch line (63), the horizontal pipe not shown.

"Operation of auxiliary support (P)"
As seen in FIG. 1, the intersections of the X axis (62) and the Y axis (63) connected and supported by the other end of the peak (60) fixed at one end to the top of the middle column (6) are respectively The fruit tree (ft) and the branch (B) are fruited in the air 1.5 to 2.0 meters from the ground surface (40) by the ridge line pulled to the top side of the middle pillar (6). Usually cultivated. And since this fruit (F) reaches the typhoon season and the harvest time is coarse, fruit trees (ft) and branches (B) are struck by strong winds such as typhoons, and the fruit (F) also moves up and down and falls ( The product value of F) is significantly reduced. The installation work of the auxiliary column (P) for preventing such damage will be described with reference to the drawings.

  As shown in Fig. 1, the upper end of the auxiliary strut (P) is positioned near the branch (B) where the fruit (Fd) has fallen due to a strong wind such as a typhoon and the fruit (F) is feared to fall. Then, the spiral pile (4) provided at the lower end (21) of the outer pipe (2) is turned into a ground (41) by rotating a lever (56) described later, thereby moving the outer pipe (2) up and down. It is possible to prevent the auxiliary strut (P) from standing in a desired position easily and quickly.

  As shown in FIG. 2 (a), the lever shown in FIG. 2 (b) and FIG. 2 (c) showing the holding portion (5) disposed on the upper end (20) of the outer pipe (2) in an enlarged manner. (56) is rotated so that the space between the notches (58) opens, that is, the holding portion (5) is in the non-holding state, and the substantially axial centers of the inner pipe (1) and the outer pipe (2). Centering on (C), the rotation in the circumferential direction and the movement in the axial direction can be freely performed, and the dimension in the axial direction of the auxiliary column (P) can be arbitrarily adjusted.

What is seen in FIG. 3 is a gripping part (50) that grips and rotates when the movable arm (31a) and (31b) are opened and closed to form the opening (37) of the receiving part (3). By rotating the helical male screw (35) formed in the integrally formed and rotating helical pipe (36), a helical nut having a helical female screw and not rotating is generated in the helical female screw (38). A thrust directed toward the upper end (10) of the inner pipe (1) is transmitted to the link (33).
The movable arms (31a), (31b) are pushed open by this thrust, and the state where the opening (37) is opened to the maximum is shown.

  From the state shown in FIG. 3, the holding part (50) is rotated in the direction in which the opening (37) is closed, and the receiving part (3) is opened in a state where the opening (37) is appropriately opened. As shown in FIG. 1, the protective material (pt) attached to the branch (B) in the vicinity of the fruit (Fd) near the fruit (Fd) that is preliminarily swung under the influence of the typhoon and is predicted to cause fruit fall damage is captured, The holding part (50) rotates in the direction in which the opening (37) of the receiving part (3) closes, and captures and binds the branch (B) as seen in FIGS. 2 (a) and 4.

  In this way, the lever (56) shown in FIGS. 2 (b) and 2 (c) is cut out while maintaining the state in which the branch (B) is securely captured and bound to the receiving portion (3). 58), the nut (55) and the abutting portion (57) are pulled toward each other to narrow the gap between the notches (58), and the band (59) and the seating surface (55a), ( 55b), the outer peripheral surface of the inner pipe (1) is tightened by the inner peripheral surface in the vicinity of the upper end (20) of the outer pipe (2), and the auxiliary strut P is prevented from rotating and moved in the axial direction. Is restrained, and the length of the auxiliary column P is fixed. Thus, since the distance between the ground surface (40) and the branch (B) is reliably determined, the branch (B) is prevented from being swung up and down by an external force such as a typhoon, and there is a concern that the fruit will fall. It can prevent fruit drop damage (Fd).

What is seen in FIG. 5 represents a state where the branch (B) having a much smaller diameter is captured and bound to the diameter of the branch (B) captured and bound to the receiving part (3) shown in FIG. ing.
As described above, according to the present embodiment, it is possible to quickly capture and bind in accordance with the diameters of various branches (B).

  As shown in FIG. 2 (c), the lever (56) is formed long in the circumferential direction at a substantially right angle from the axis of the bolt (54) which is the rotation shaft when the lever (56) is rotated. Since the working radius is large and the operation can be performed with a relatively small operating force (rotation force) applied to the lever (56), the upper end of the outer pipe (2) can be easily operated even by a relatively weak elderly person and a woman. The band (59) arranged in the vicinity can reliably prevent the inner pipe (1) from moving in the axial direction and increase the restraining force. Can reduce the fatigue of the operator and improve the work efficiency.

  Furthermore, the lever (56) is operated from the central axis (C) of the outer pipe (2) when the spiral pile (4) fixed to the lower end of the outer pipe (2) is buried in the ground (41). Because the turning radius is large, it is possible to embed and extract the spiral pile (4) easily even by relatively incompetent elderly people and women, so the auxiliary strut (P) can be installed and removed quickly. .

Moreover, the structural member (Cs) which forms a fruit shelf, such as the X-axis branch line (62) and the Y-axis branch line (63) seen in FIG. 7, can be supported by the receiving portion (3) and used as a fruit tree shelf reinforcing column.
And since it can be installed and withdrawn easily and quickly, when the auxiliary strut (P) is used as a conventional fixing strut, a fruit tree shelf can be constructed in a short period of time and at a low cost.

  In addition, the present invention is not limited to the above-described embodiments, and the configuration and components can be changed, added, and recombined without departing from the gist of the present invention.

As described above, when it is predicted that a typhoon will strike, the auxiliary strut P is used to simply and quickly reinforce the fruit shelf, and after passing the typhoon, the cultivation land surface (40) and the fruit shelf In order to form the manure management space (43) required below, the auxiliary strut P can be easily and quickly removed, and the manure management space (43) is secured.
In this way, it is possible to prevent typhoon damage, and the auxiliary strut (P) does not interfere with normal manure management work, so the productivity of the orchard can be increased.
