Description

  The present invention relates to a pruning shoot used in landscaping, fruit gardening, and the like, and a fruit harvester for harvesting fruits grown in high places in fruit tree cultivation.

  It has been performed by some fruit-cultivating farmers so far to attach a fruit receiving container or the like to a high branch pruning basket widely used in landscaping, fruit gardening, etc. and to use the pruning basket as a fruit harvester.

  However, the conventional pruning pruner has a straight line from the long handle to the top of the top, and it is difficult to reach the pear from the bottom of the fruit tree toward the fruit in the center of the upper surface of the large swollen fruit. was there.

  The present invention was devised in order to remove such difficulties associated with conventional high branch pruning shears and to realize a high branch pruning shear that can be easily converted into a fruit harvester.

Means to solve the problem

Constitution

  The high branch pruning basket of the present invention is mainly composed of a long handle (1), a basket (3), and a handle (8). When this is used as a fruit harvester, a removable hopper duct (14) is a separate component. To join. A hook is attached to the tip of the long handle, a hopper duct is attached slightly to the rear of the tip, and a handle is attached to the rear of the longer handle.

  The long handle (1) is a straight pipe having a length suitable for work, and a drawer opening (1a) is opened at an intermediate portion thereof.

  The frame (2) is fixed to the tip of the long handle (1), the tip of the frame has a bending shaft (4), and the collar (3) is pivotally attached to the bending shaft, Further, there is a grip bolt (5) on the bent shaft portion. That is, the flange is attached in a state where the angle can be changed at the bent shaft portion.

  The scissors are composed of a fixed blade (3a) and a movable blade (3b), and a spring (6) is provided on the base side surface of the fixed blade and normally urges the movable blade to open.

  The inner cable (7a) of the cable wire (7) is engaged with the movable blade (3b) while being inserted through the coiled spring (6), and the cable wire is attached to the rear of the long handle. The handle (8) is engaged.

  The cable wire (7) is generally called a Bowden cable, and an inner cable (7a) made by twisting many thin steel wires is covered with an outer tube (7b, 7e) in which the steel wires are wound spirally. It is in a wrapped structure and can be bent relatively flexibly. The cable wire is inserted into the inside of the pipe-shaped long handle near the tip of the long handle (1), is led out of the long handle from the outlet (1a) opened in the middle of the long handle, and engages with the handle (8). ing. Further, the outer tube is divided into two near the outlet, the front fixed outer tube (7e) is fixed to the side surface of the fixed blade (3a) of the heel, and the rear movable outer tube (7b) is the rear end portion. Is in contact with the terminal locking member (7c) of the inner cable. That is, the inner cable (7a) is encapsulated in the fixed outer tube (7e) from the front end to the vicinity of the outlet (1a), and is encapsulated in the movable outer tube (7b) from the vicinity of the outlet to the rear end.

  The handle (8) is attached to the rear side of the long handle with the long handle inserted into the upper cylindrical portion. If the handle bolt (9) is loosened, the handle (8) can be extended from the outlet (1a) to the rear end of the long handle. It is possible to slide along the long handle and adjust the angle with the long handle as the central axis.

  The handle (8) has a lever pin (11), to which a lever (10) is pivotally attached. The lever is further divided into two at the sub-lever pin (12), and the lever lower piece (10a). ) Can be rotated in the direction opposite to the handle.

  The lever upper piece (10b) is biased forward by a spring (13), and the lever lower piece (10a) hangs from the sub lever pin (12) within the restriction range of the stopper.

  The cable wire (7) is inserted between the lower end surface of the lever upper piece (10b) and the upper end surface of the lever lower piece (10a). It is. However, when the lever lower piece is pulled in the handle direction, the lower end surface of the lever upper piece and the upper end surface of the lever lower piece face each other to form a clamping body, and the movable outer tube of the cable wire inserted between the both end surfaces ( 7b) is held.

  The opposing surface of the sandwiched body is subjected to a process that suppresses wear of the movable outer tube that is the sandwiched object and ensures grasping.

  The rear end portion of the cable wire (7) inserted between the sandwiching bodies extends rearward from a through hole (8a) opened near the grip portion of the handle, and at the rear end portion, a terminal sleeve ( 7d) is in contact with the terminal locking member (7c) of the inner cable.

  Another part is a cylindrical hopper duct (14) made of a material such as fabric or vinyl sheet. The hopper duct is attachable to and detachable from the long handle (1) at the hook (14d), and several drop suppression bands (14a) are formed in the middle of the hopper duct, which is a circular elastic band material. . The length of the hopper duct is sufficiently long to reach the ground from the height of the fruit growing at the top.

Functions and interrelationships of each part

  The long handle (1) facilitates the approach to pruning branches or harvesting fruits.

  The frame (2) serves to attach the heel (3) to the long handle (1) with the bending shaft (4), and the bending shaft (4) and the grip bolt (5) Allows adjustment of the posture angle.

  The cable wire (7) transmits the driving force when the rear handle (8) is operated to the flange (3) at the tip. At that time, the fixed outer tube (7e) serves to guide the movement of the inner cable (7a) in the vicinity of the bending axis (4) where the curve is particularly steep and within the long handle (1).

  The handle (8) functions to operate the heel, and when the lever lower piece (10a) of the handle is gripped, the upper end surface of the lever lower piece and the lower end surface of the lever upper piece (10b) constitute a clamping body. The movable outer tube (7b) of the cable wire inserted between them is pinched and pulled backward.

  It is the movable outer tube (7b) that the lever (10) holds and pulls backward, and the terminal sleeve (7d) of the movable outer tube abuts on the terminal locking member (7c) of the inner cable at the rear end. Then, the driving force is transmitted to the inner cable, and with this movement, the movable blade (3b) at the distal end rotates to close the blade.

  When the lever lower piece (10a) is released, the engagement relationship between the handle (8) and the cable wire (7) is broken, so that the movable blade (3b) is opened by the urging force of the spring (6).

  The cable wire (7) is not clamped except when the lever lower piece (10a) is pulled. The handle can be adjusted according to the distance from the target branch or fruit and workability by simply loosening the grip bolt (9). The position and posture angle can be adjusted.

  The hopper duct (14) is a part that is used only during fruit harvesting. It functions to induce the fall of the fruit harvested by cutting the fruit stem to a collection basket placed on the ground, and the fall restraining band (14a) drops the fruit. Slow down to prevent damage.

  The hook (14d) allows the hopper duct to be attached and detached, and the grip bolt (14e) serves to fix the hook to the long handle.

how to use

  There are two methods of using this instrument depending on its purpose, that is, when it is used for branch pruning and when it is used for fruit harvesting.

  When this instrument is used for branch pruning, remove the hopper duct (14), loosen the grip bolt (5) near the end of the long handle and straighten the heel (3).

  When it is necessary to adjust the distance from the branch to be cut, the handle bolt and the posture angle are adjusted by loosening the grip bolt (9) of the handle (8).

  When the scissors reach the target branch, grasp the handle and pull the lever (10).

  When this instrument is used for fruit harvesting, the hopper duct (14) is attached to the long handle, and the cocoon (3) is bent at an angle suitable for the cut of the curd.

  A basket or the like for collecting the harvested fruit is prepared in advance and placed under the fruit tree, and the lower end of the hopper duct (14) is inserted and placed therein.

  To adjust the distance between the user and the target fruit and the mounting angle of the handle (8), loosen the grip bolt (9).

  While guiding the tip so that the target fruit enters the hopper duct, the tip is brought close to the fruit, and the lever (10) is pulled when the bud reaches the infarction.

  Release the lever after cutting the branch or fruit. The fruit falls into the hopper duct (14) and is directed to a collection basket placed underneath.

  When storing the instrument after use, pull the handle (8) toward the rear end, pull the cable wire end sleeve (7d) backward with the through hole (8a), and at that position, hold the bolt (9) Tighten. As a result, storage with the bag closed is possible.

Effect of device

  By using the high-pruning pruner of the present invention, it is easy to cut the fruit, and the diversion as a fruit harvester becomes more effective.

Example of use

  So far, when the device of the present invention is used for fruit harvesting, examples of use in which the fruit cut from the fruit stem is guided to the straw placed under the fruit tree through the hopper duct (14) have been shown. There are many types that require special handling. In such a case, it is necessary to install a relatively shallow bag or the like instead of the hopper duct to shorten the fruit fall distance to prevent damage. An example of use in which the receiving bag (15) is thus mounted is shown in FIG.

Best mode for carrying out the invention

  In the structure of the present invention, the movable parts such as the bending shaft and the spring are exposed to the outside of the long handle, which may interfere with the branches and leaves and reduce the workability. In order to solve this problem, it is desirable to cover the periphery of the bending axis with a cover made of a flexible material such as rubber and having a structure that does not hinder the operation of the grip bolt.

  When carrying out the present invention, it is desirable to use a cable wire that can be flexibly bent as the linear driving force transmission member, considering that the heel is bent and stretched at the bending shaft portion. At that time, it is possible to use only the inner cable made by twisting the steel wire, but if the inner cable is directly clamped while securing the operation position, is it possible to obtain sufficient grasping power? If the measure for increasing the grasping force is taken, the inner cable may be worn out at an early stage, and the mobility of the operation position is also impaired. From the viewpoint of preventing this wear and securing the grasping force of the cable wire, avoid the direct clamping of the inner cable by the clamping body of the lever part, and sandwich and move the movable outer tube as a primary linear driving force transmission medium, It can be said that it is a good measure to transmit to the inner cable secondarily.
