Description

  The present invention relates to a fruit transport for transferring harvested fruits directly to a transporting basket, which is a conventional harvesting operation in which an operator transfers fruits harvested with a basket to a transporting basket.

  Conventional citrus harvesting work is usually done by cutting fruit from the branches of fruit trees and storing it in shoulder bags or caskets, and when it is full, it is transferred to a transporting jar placed on the ground. It has been inherited. Although this harvesting work depends on the type of citrus fruit, the weight of the full harvest in a shoulder bag or a basket is about 10 kilograms, which is a heavy burden on women and the elderly.

  In addition, in the case of Takagi's fruit field, it is a harvesting work on ladders and stepladders, and working with heavy straw at high places not only increases instability, but also the freedom to move the body worsens, The efficiency of the harvesting operation becomes worse in proportion to its weight.

  In addition, when using ladders or stepladders in orchards on sloping terrain, it is necessary to pay attention to stability, and working at heights with bags and straws heavy with harvested fruits increases the risk of falling accidents.

  Since it is accompanied by the conventional harvesting of citrus fruits using shoulder bags and bags, it is an object to reduce the burden on the body and improve the safety of operations performed using ladders and stepladders.

  The invention of claim 1 is a conveying tube (having a slot or a ring arranged at regular intervals, provided with an input port (A) and a carry-out port (C) between a harvesting place and a transport basket (a). The fruit harvesting aid according to claim 1, wherein the cut fruit is directly stored in the transporting basket (a) by B).

  The invention of claim 2 is a tensioned state of the guide string (7) for adjusting the tension and the tension state of the adjusted guide string (7) so that the fruit does not stay in the transport tube (B) and passes smoothly. A guide string stopper (3) that can be easily maintained and released is provided.

  Moreover, in order to prevent the fall of the fruit by the space | interval which arrange | positioned the spiral or ring-shaped tube cord (8) which forms the conveyance tube (B) at a fixed space | interval too much open, the space | interval does not open more than fixed. A fruit harvesting aid according to claim 1, characterized by having a keep cord (9).

  According to the invention of claim 3, the hard resin wire which is the spirally wound tube cord (8) forming the transport tube (B) is manufactured by the repulsive force of the material. 3A is released from the constrained state, the winding diameter is wound in the circumferential direction as shown in FIG. 3B, and the spiral diameter is increased because the circumferential length is increased accordingly. It becomes larger, and the spiral interval is also reduced as shown in FIG. At this time, the transfer tube (B) rotates in the direction of the spiral line. When this rotational movement is restricted and expanded and contracted, the transport tube (B) is twisted and the fruit cannot pass. For this reason, by connecting the hopper (4), which is the insertion port (A), and the grip handle (1) to a structure in which the rotor (6) can rotate around the hollow shaft (5), the grip handle (1) 2. The carrier tube (B) below the hopper (4) can be freely rotated when the carrier tube (B) is expanded and contracted by holding, so that no twist is generated. As a fruit harvesting aid.

  According to the invention of claim 4, the structural material of the transport tube (B) is spirally wound with a stretched material such as a hard resin wire at a constant interval, so that the spiral interval is increased in proportion to the length to be stretched. Since the fruit passes through the spiral interval, the fruit passing speed becomes more effective as the spiral interval becomes wider.

  Therefore, when the distance from the transporting basket (a) to the harvesting place is long, especially in the case of harvesting work at a high place such as a stepladder, this deceleration effect is effective for the conveying tube (B) that brings about a good effect that does not cause fruit damage. The fruit harvesting aid according to claim 1

  According to the invention of claim 1, there is no need to carry a shoulder bag or a bag with the cut fruit as in the prior art, and the cut fruit is directly placed in the transporting basket (a) via the transport tube (B). The physical burden on the worker can be reduced because the body does not receive the cumulative load of fruits due to the harvesting work.

  In addition, even in harvesting work at a high place by ladders or stepladders, the balance of the body is lessened because the accumulated load of fruits is not received by the body, and safety is improved.

  According to the invention of claim 2, the guide string (7) for adjusting the tension condition and the adjusted guide string (7) for allowing the fruit to pass smoothly without passing through the transfer tube (B). Since the guide string stopper (3) that can easily maintain and release the tension state is provided, the fruit harvesting auxiliary tool can be quickly operated with one hand.

Also, the nylon tube cords (8) with a diameter of 3.5 mm that make up the transport tube (B) are arranged in a spiral at regular intervals, and the spiral is kept constant with the keep cord (9) made of a thin polyester cord. By adopting a simple configuration with fixed spacing, it is lightweight and easy to carry.
In addition, this fruit harvesting auxiliary tool has an expansion / contraction difference of about 80 times from the contracted state of storage to the longest, and can cover a wide range of harvesting work area from the transporting basket (a). Improvement can be expected.

  According to the invention of claim 3, the rotor (6) rotates around the hollow shaft (5) for connecting the hopper (4) that is the inlet (A) of the transfer tube (B) and the grip handle (1). Since it is connected to the transport tube (B) with a structure that can be used, the transport tube (B) can be smoothly moved when the operator holds the grip handle (1) and performs an expansion / contraction operation.

  According to the invention of claim 4, the structural material of the transport tube (B) is spirally wound with a tight material such as a hard resin wire at a constant interval. Because it passes through the spiral, it receives rolling resistance, and the deceleration effect becomes stronger. Further, the spiral interval width is regulated by the keep cord (9), and the upper limit of the deceleration effect more than necessary is also decided by the keep cord (9), which is a function friendly to harvested fruits.

  As an example of the embodiment of the present invention, a fruit harvesting aid will be described using citrus fruits as a harvesting target. FIG. 1 shows a fruit harvesting aid of the present invention, A in FIG. 1 shows a slot into which fruit is placed, B in FIG. 1 shows an intermediate portion of the fruit harvesting aid, and C in FIG. Yes. FIG. 2 is a carry-out port C of the fruit harvesting auxiliary tool, which represents a function of reducing a drop impact on the fruit. FIG. 3 is a diagram showing a change in shape when the conveying tube is expanded and contracted.

  As shown in FIG. 1, the fruit harvesting auxiliary tool according to the present invention has a grip handle 1 for extending and retracting the transport tube B at its tip, and the grip handle 1 includes a fruit tree branch and an operator's breast pocket ( A hanger 2 for hooking to a not-shown) and the like, a cord stopper 3 for fixing the length of the transfer tube B at an arbitrary position, and a hopper 4 as an input port A for harvested fruits. Since the grip handle 1 is connected so that the rotor 6 can rotate around the hollow shaft 5, the transport tube B including the hopper 4 does not twist. Further, the transport tube B includes a guide string 7 for adjusting the tension of the transport tube B and a keep cord 9 that does not open the distance between the transport tubes beyond a certain level. At the end of the transport tube B, there are a carry-out port C for gently storing the fruit in the transport basket and a stand b for fixing the end portion of the transport tube B to the transport basket a.

First, the structure of the slot A will be described.
The grip handle 1 is attached with a hanger 2 for hooking onto a branch of a fruit tree or an operator's breast pocket and a cord stopper 3 for fixing the length of the transport tube B at an arbitrary position.
A hollow shaft 5 on which a rotor 6 is set is attached below the grip handle 1. The rotor 6 and the hopper 4 are connected by a connecting string 10 to constitute a slot A.

  According to the above configuration, the grip handle 1 is hooked on the target branch with one hand, the cord stopper 3 is pushed, the guide string 7 protruding upward through the grip handle 1 is adjusted while releasing the lock, and the harvest is quickly performed. Work is started.

  Further, since the transport tube B below the hopper 4 can be freely rotated by the rotor 6 set on the hollow shaft 5, it has a structure that does not twist even when the telescopic operation is performed.

Next, the conveyance tube B will be described.
Among the parts constituting the fruit harvesting auxiliary tool shown in FIG. 1, the most main part, the transport tube B is spiral, and the structural material forming the spiral is a hard resin wire or the like. A material with a diameter of 3.5 mm is spirally wound at regular intervals, and keep cords 9 that keep the wound intervals from opening beyond a certain distance are divided into 4 rows at intervals of 4 equal parts in the circumferential direction of the spiral. Deploy. This state is shown in FIG. In addition, the inner diameter and the spiral interval wound in a spiral were set to an inner diameter of 110 mm and a spiral interval of 40 mm sufficient for the smooth passage of citrus ponkan and tankan, which are fruits to be harvested. In addition, it is desirable that the inner diameter and the spiral interval be adapted to the size of the fruit to be harvested. In addition, the structure of the tube may be a structure in which a ring shape other than a spiral shape is continued at a constant interval.

  A structure in which a diameter of 3.5 mm is spirally wound at a constant interval with a stretched material such as the hard resin wire of the embodiment shown in the present invention changes as follows. Due to the repulsive force of the material, the spirally wound hard resin rod has a spiral structure that is fixed for the manufacture of the transport tube, which is manufactured at regular intervals as shown in FIG. When the hard resin wire of the material is released from its restraint, the winding diameter is repelled by the repulsive force, the length L of the keep cord 9 is wound in the circumferential direction, and the spiral diameter is increased accordingly, and the helical spacing is also increased. It shrinks as shown in B of FIG. This state is a contracted state in which the fruit harvesting auxiliary tool of the present invention is housed, and when it is most extended, the state becomes A in FIG.

  Therefore, the structure that is continuous at regular intervals by the spiral is increased to the diameter plus the length L of the keep cord, and the total number of turns forming the tube is reduced by the increased diameter, which helps to make the storage compact. ing.

Next, the carry-out port C will be described.
The carry-out port C in FIG. 1 receives the fruit that has passed through the transfer tube B by a shock-absorbing structure that bends in a U-shape, and is guided downward by gravity. Drop to (a). The state is shown in FIG.

  The impact absorbing structure regulates the lower horizontal extension of about 10 layers of the spiral end portion of the transport tube B, so that the fruit that reaches the carry-out port C pushes the spiral end portion. It falls down while spreading in a U shape. As shown in the time series of (A), (B), and (C) in FIG. 2, the fruit that has passed through the transport tube B loses speed and functions to fall gently.

  In the case of citrus fruits, the diameter of the transfer tube (B) and the pitch of the keep cord (9) are optimized to the size of the target fruit, so that the citrus fruits can be applied to a wide range of citrus fruits.
