  When it is desired to lengthen the rod 2, an appropriate number of extended rods 2b are connected to the other end (base end side) of the working rod 2a provided with the working portion 3 via the joint portion 5 having the configuration shown in FIGS. It is extended by doing. As a result, the worker can collect the ridges and the like at a high place while standing on the ground or climbing on a stepladder or the like.

  The work operation units 4 and 4 are formed of a pair of hemispherical bowl-like or bowl-like shapes that accommodate and hold the bucket 7 by using a lightweight metal mesh or plastic material. Has been. The work rod 2a and the extension rod 2b are made of aluminum pipes or glass fiber pipes, and the lengths of the rods are, for example, about 140 cm and easy to handle.

  The saddle 2 in the illustrated example is in the middle of the saddle between the working part 3 and the operation tool 9 provided on the most proximal side in the state where the working saddle 2a and the extension saddle 2b are connected via the joint part 5. One or more midway operation tools 9a that can open and close the work operation units 4 and 4 from the unit are provided. The intermediate operation tools 9a, 9a,... Are connected to the middle part of the interlocking member 13 built in the work rod 2a and the extension rod 2b, and the interlocking member 13 is reciprocally interlocked in the same manner as the operation tool 9 by the operation. The work operation units 4 and 4 can be opened and closed via

  The detailed structure of each part will be described below. First, as shown in FIG. 2, the working part 3 is detachably attached and fixed by the attaching screw 11 in a state where the attaching cylinder 10 is inserted into the distal end part of the working rod 2a. The mounting cylinder 10 includes an opening / closing mechanism 3a configured to open / close the work operation units 4 and 4 based on the operation of the operating tool 9 and the midway operating tool 9a as follows.

  That is, on the distal end side of the mounting cylinder 10, the operation holes 15, 15 for inserting the operation pieces 12, 12 of the work operation units 4, 4 separately from the left and right are notched, and an intermediate position between the operation holes 15, 15 is formed. The horizontal support shaft 16 is supported on the side. And the middle part of the action | operation pieces 12 and 12 inserted in the action | operation holes 15 and 15 is pivotally supported by the spindle 16 so that rotation is possible.

  Further, a hook holder 19 for inserting and supporting the interlocking rod 17 of the interlocking member 13 so as to be slidable in the vertical direction is provided in the middle portion of the mounting cylinder 10. The saddle holder 19 is provided at its lower part with a spring holder 21 that supports a spring 20 that urges the interlocking member 13 in the returning direction (direction in which the work operation units 4 and 4 are closed). Reference numeral 22 denotes a lid for closing the upper end opening of the mounting cylinder 10 so that it can be opened and closed.

  The interlocking member 13 housed in the work rod 2a shown in FIG. 2 includes the interlocking rod 17 and a rope 23 composed of a wire member, and a rod 25 that couples both together so that the distance can be adjusted. The spring 20 is supported in a compressed state between the spring holder 21 and the interlocking rod 17 in a state where the spring 20 is fitted into the rod 25.

  The interlocking rod 17 is provided with a horizontal operation pin 26 on the head, and an operation hole 27 formed in the operation pieces 12 and 12 is inserted into the operation pin 26. The operating pieces 12 and 12 are formed in a symmetrical L-shape as shown in the figure, and the operating hole 27 is formed in a rectangular shape in the other lower piece portion to which the work operating portions 4 and 4 are attached and fixed. As a result, a regulating mechanism as described below is configured.

  That is, the regulating mechanism places the work operation parts 4 and 4 in the closed position at the position where the vertical groove 27a on the upper part of the operation hole 27 engages with the operation pin 26 as shown in FIG. When a force in the opening direction is applied to 4, 4 itself, the longitudinal groove portion 27a contacts the operating pin 26, thereby restricting the opening operation of the work operation portions 4, 4.

Then, when the operation tool 9 or the midway operation tool 9a is operated from the closed state in the work operation parts 4 and 4, and the operation pin 26 moves downward, the operation pin 26 is detached from the longitudinal groove part 27a, and the operation hole 27 is moved through the slope part of the operation hole 27. The working pieces 12 and 12 can be rotated around the support shaft 16 to forcibly open the work operation units 4 and 4 to switch to the open posture shown by the dotted line in FIG.

  Further, the second guide 35 is provided symmetrically across the joint portion 5 with the same structure as that of the first guide 30 at the distal end portion of the extension rod 2b. An intermediate operation tool 9a is configured by providing a shaped member. And the 1st guide 30 and the middle operation tool 9a similar to the thing of the said work rod 2a are comprised by the base end part side of this extension rod 2b. Further, the first guide 30 and the second guide 35 in the extension rod 2b are connected by a rope-like interlocking member 13.

The connecting member 13a is configured such that the end portions of the interlocking member (rope) 13 on the work rod 2a side and the interlocking member (rope) 13 on the extension rod 2b side are connected to the locking member 32 of the first guide 30 by a connecting structure described later. The locking member 32 of the second guide 35 on the extension rod 2b side is detachably connected.
When the extension rod 2b is connected to the work rod 2a via the joint portion 5, the first guide 30 of the extension rod 2b on which the operation tool 9 of the rod 2 that has been connected and extended becomes the most proximal end side (hand side). This corresponds to the operation tool provided in the above.

  Next, the joint 5 that sequentially connects the work rod 2a and the extension rod 2b and the extension rod 2b and another extension rod 2b will be described. This joint portion 5 has a pipe-like connection member 37 attached and fixed in the opening on the base end side of the work rod 2a and the extension rod 2b, and the protruding end of the connection member 37 is inserted into the distal end opening of the extension rod 2b. It is configured to be removably inserted and connected.

Further, a locking projection 39 is provided on the outer peripheral surface of the protruding end of the connection member 37, and the locking projection 39 is engaged with and disengaged from a hook-like engagement groove 40 formed in the opening end of the extension rod 2b. It is set as the structure meshed | engaged possible. As a result, the connected work rod 2a and extension rod 2b can be prevented from coming off, and the meshing can be released by a reverse operation.
When the extension rod 2b is connected to the work rod 2a as described above, the installation of the connecting member 37 is omitted on the base end side of the extension rod 2b which is the most proximal end side (connection end side). Can do.

  Next, the connecting structure of the working members 2a and the extension rods 2b and the operating members 13 and 13 housed in the extension rods 2b and another extension rod 2b will be described. In this connection structure, the locking member 32 and the locking member 32 respectively provided on the first guide 30 and the second guide 35 provided on each ridge are projected from the guide hole 33 of each ridge to the heel surface side. The locking member 32 and the locking member 32 are configured to be detachably connected by the connecting member 13a.

  That is, as shown in FIG. 3, the second guide 35 provided at the tip of the extension rod 2 b fits and supports the mounting piece 50 on the protruding side of the locking member 32, and the mounting piece 50 has flexibility. A connecting member 13a made of a rope or string member is attached. The connecting member 13a is provided with a locking portion 51 that is connected to the locking member 32 side of the first guide 30 at the other end.

  On the other hand, the locking member 32 of the first guide 30 is rotatably provided with an engaging portion 52 that is detachably engaged with the locking portion 51. The engaging portion 51 and the engaging portion 52 in the illustrated example are hook-type connecting means that are detachably connected by press fitting, and the connecting member 13a can be quickly connected by a one-touch operation. . With the above-described structure, when the extension rod 2b is sequentially connected to the work rod 2a, the link member 13 on the distal end side is reciprocated when an arbitrary midway operation portion 9a is operated. The interlocking member 13 on the end side is prevented from operating by bending the connecting member 13a as shown by the dotted line in FIG. 3, so that the intermediate operation unit 9a and the operation tool 9 linked to the interlocking member 13 are in the operation standby posture. Can be held in.

  Further, since the midway operating tool 9a including the connecting member 13a is provided at the distal end portion of the extension rod 2b to be coupled, on the proximal end side of the work rod 2a and the proximal end portion side of the extension rod 2b coupled to the work rod 2a, There is no hindrance without hanging the interlocking member 13. The connecting member 13a is not limited to the above-described connecting means, but can be a hook-type connecting means or a connecting means such as a string tie with respect to the locking member 32 on the first guide 30 side.

Next, the working unit 3 will be described with reference to FIGS. The work operation parts 4 and 4 are formed of a pair of left and right symmetrical hemispherical bowl-like or bowl-like work parts with respect to the operating pieces 12 and 12, and the base side is detachably attached and fixed by attachment screws 55. The

  Then, the work operation units 4 and 4 separate the openings of the left and right buckets 7 and 7 with an accommodation interval into which the stems of the rods can be inserted in a closed collection posture for collecting the rods. . The working unit 3 having the above-described configuration and having an accommodation interval can grip the bag by the working operation units 4 and 4 even if the buckets 7 and 7 are shallow. In addition, when operating the operation tool 9 or the midway operation tool 9a to discharge the trap that has been stored and gripped, the opening amount of the work operation units 4 and 4 can be reduced by the storage interval, so that the opening and closing operation can be performed easily and quickly. There is an advantage that can be performed.

  Furthermore, since the upper portion of the edge frame 56 is supported in a cantilever state by the support frame 57, the bucket 7 can be deformed in accordance with the size and shape of the cage to be accommodated and can be gripped without difficulty. In addition, the bucket 7, the edge frame 56, and the support frame 57 are determined in a shape suitable for the fruit to be collected and accommodated.

  The work tool 1 configured as described above opens and operates against the spring 20 that operates the midway operation tool 9a or the operation tool 9 to bias the pair of work operation units 4 and 4 in the closing direction. When the operation is canceled by putting the formed heel between the work operation parts 4 and 4, the work operation parts 4 and 4 can be held in a state of being held. Next, by pushing or pulling or twisting the scissors 2, the scissors can be collected smoothly so that the scissors can be removed from the branches by hand. In this sampling operation, the operator can open and operate any midway operation tool 9a or operation tool 9 located at the nearest position where the handle 2 is gripped.

  Next, the work tool 1 in which the scissors are collected in the work unit 3 has the work operation units 4 and 4 maintained in the closed state by the restriction mechanism to prevent accidental opening, and the operator can freely retake the scissors 2 to branch the work tool 1. And the collected soot can be smoothly transported to a collection unit prepared in the vicinity of the worker.

  At this time, in the state where the working unit 3 is moved toward the collecting unit, the gripping position of the basket 2 is different from the position at the time of sampling. The midway operation tool 9a can be quickly operated in the opening direction, and the bag discharging operation is not performed in an unreasonable posture.

Next, another embodiment of the opening / closing mechanism 3a and the regulating mechanism that opens and closes the work operation units 4 and 4 based on the reciprocation of the interlocking member 13 will be described with reference to FIG.
