Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method for producing a fruit tree,
The present invention relates to a perforation and fertilization device having a structure for performing fertilization while digging a deep hole, also serving as air supply.

[0002]

2. Description of the Related Art In an orchard or the like, it is effective from the viewpoint of cultivation to dig a deep hole at the root of a fruit tree for air supply and to apply additional fertilizer therein. Such a machine that is applied so as to dig a deep hole during fertilization has never before been manually drilled.

[0003]

In a wide orchard or the like, it is necessary to perform a hard work on topdressing while performing such drilling work at the root of each fruit tree.

[0004]

The present invention uses the following means to solve the above problems. That is, instead of a bucket of a power shovel, a pile-shaped piercing claw is provided at the tip of the arm, and a hopper for storing fertilizer is provided above the piercing claw, and a feeding device for feeding a fixed amount of fertilizer from the hopper is provided. Then, a perforated fertilizer is used.

[0005]

Embodiments of the present invention will be described with reference to the accompanying drawings. 1 is an overall perspective view of a perforating and applying apparatus of the present invention, FIG. 2 is a side perspective view of a perforating section and a fertilizer feeding section mounted on the tip of an arm, FIG. 3 is a rear perspective view of the same when fertilizer is sprayed, and FIG. FIG. 4 is a wiring diagram illustrating a configuration of a switch for switching the feeding device by operation.

The boring and fertilizing apparatus according to the present invention basically has a structure shown in FIG.
As shown in the figure, a drilling claw 1 is attached to the tip of an arm 8 of a power shovel instead of a bucket, and a hopper 5 for storing fertilizer and a feeding device 3 are disposed above the claw 1.

The configuration of the power shovel will be described with reference to FIGS. 1 and 2. The main body 14 is rotatably mounted on the crawler traveling device 17, and a rear portion of the main body 14 is a hood 14 a for an engine room, and a seat 16 is disposed thereon, and a seat 16 is provided in front of the seat 16. An operator sitting on the seat 16 places a foot thereon, or a floor surface 14b serving as a step when getting on and off is formed, and a front column 15 is erected in front of the floor surface 14b, and various levers are protruded. Various pedals are arranged at the feet.

A boom bracket 13 is provided at the front end of the main body 14, and the base end of the boom 11 is pivotally supported by the boom bracket 13 so as to be able to rotate back and forth. A hydraulic boom cylinder 12 is connected to a middle part of the abdominal surface of the boom 11. A base end of an arm 8 is pivotally supported at the front end of the boom 11 so as to be able to rotate back and forth. A hydraulic arm cylinder 10 is connected to the base end of the arm 8 from a middle part of the back surface of the boom 11. Further, a bucket link 7 is pivotally supported at the tip of the arm 8 as shown in FIG.
A hydraulic bucket cylinder 9 is connected to a bent portion of the bucket link 7 from the back of the bucket.

In a conventional power shovel, instead of a bucket pivotally supported by the tip of the arm 8 and the tip of the bucket link 7, the perforation claw bracket 2 is pivotally supported, and the perforation claw 1 is supported by this. In this embodiment, the perforation claw is welded and fixed to the perforation claw bracket 2. However, in order to further enhance the perforation effect, the perforation claw 1 is supported so as to slide (vibrate) with respect to the perforation claw bracket 2. Alternatively, the perforating claw 1 may be vibrated by hydraulic pressure or the like.

[0010] With the mounting of the perforation claw 1, the operator places the perforation claw 1 at a target perforation position by turning the main body portion 14 of a normal power shovel or operating the boom 11 and the arm 8. Similarly to the operation of the bucket, the drilling claw 1 (and the drilling claw bracket 2) can be rotated back and forth with respect to the tip of the arm 8 by driving the bucket cylinder 9, and the positioning of the drilling is performed by this rotating operation. And a perforation operation can be performed.

Further, in this drilling / fertilizing apparatus, a feeding portion support 2a is provided upright above the drilling claw bracket 2 to enable fertilization while drilling, and the feeding device 3 is supported thereon. A motor 4 (an electric motor or a hydraulic motor using a hydraulic cylinder for a bucket cylinder or a PTO) for driving the feeding device 3 is mounted on one side of the feeding device 3. Further, hoppers 5, 5 for storing fertilizer are arranged on the feeding device 3, and the driving of the feeding device 3 allows the hopper 5 to feed fertilizer (eg, granular fertilizer). As shown in FIGS. 2 and 3, a fertilizing hose 6 is provided at a position behind the perforating claw 1 from the feeding device 3, and the lower end opening of the fertilizing hose 6 extends along the perforating claw 1. Fertilizer can be sprayed. FIG.
Shows that the perforation claw 1 is pierced, the perforation claw 1 is pulled out from the hole H, and fertilizer is sprayed from the fertilization hose 6 into the hole H.

The switch SW of the motor 4 for driving the feeding device 3 is disposed on the front column 15 or
Alternatively, as shown in FIG.
It is possible to perform the on / off operation with. In the case of FIG. 4, when the pedal 18 is depressed, the switch SW becomes O.
N, the motor 4 is driven.

[0013]

As described above, the present invention has the following advantages. That is, by using a power shovel and mounting a perforation claw instead of a bucket as in claim 1, the operator can operate the perforation claw by the same operation as the operation of a bucket in a normal power shovel. In addition, a hole for supplying air can be easily formed at the root of a fruit tree or the like. In addition, by disposing a hopper and a feeding device above the perforating claw, it is possible to spray fertilizer such as granular fertilizer along the perforating claw, and to apply fertilizer to the hole formed by the perforating claw, thereby effectively. The effect of fertilizer can be given to fruit trees.
