Cultivated trees such as various fruit trees, mulberries, and tea have groups of roots such as branches and fine roots extending out in all directions from the taproot under the tree trunk over a predetermined area. Deep plowing using a soil crusher or the like will cut or damage these roots, so inter-tilling the soil surface leaves only traces. As a result, the soil around the root group becomes hard, inhibiting the expansion of the root group, and impairing the infiltration and absorption of fertilizers and moisture, which not only reduces yield and quality, but also shortens the lifespan of the tree. [Problems to be solved by the invention] It has been desired to use some means to crush and deepen the hardened soil where the roots protrude, but there is currently no suitable method.[Problems to be solved by the invention] The invention was developed in view of the above circumstances, and is a method for cutting off roots of fruit trees, etc.
The purpose is to provide a device for deep cultivation in orchards, etc., which crushes the soil without causing any damage. [Means for solving the problem] In order to achieve this purpose, The present invention is a deep cultivating device for cultivating areas where the roots of fruit trees protrude into the soil to a depth of 11. The device is characterized in that it is equipped with a spiral digging blade, and by rotating the rotary shaft, the digging blade is driven into the screw to a depth of -1° for deep plowing. [Example 1 Hereinafter, Embodiments of the present invention will be described with reference to the drawings.In the first embodiment of the present invention shown in FIGS. A support frame 3 of the deep cultivating device is reliably attached to the side 2.The support frame 3 extends horizontally from the rear of the tractor 1 almost horizontally. A vertical frame 4 is attached almost vertically to the vertical frame 4, and a horizontal frame A5.6 protrudes horizontally from the -1 end of the vertical frame 4. Guide rods 7, 7 are supported. Sliders 8, 8 are inserted through the guide rods 7, 7 so as to be vertically movable, and a support stand 9 is attached to the sliders 8, 8.
It is being A hydraulic cylinder 10 is installed between the support stand 9 and the horizontal frame 5, and the support stand moves up and down along the guide rods 7, 7 by the expansion and contraction of the hydraulic cylinder 10. A pair of left and right rotating shafts 11.11 are mounted vertically on the support base 9, and a hydraulic motor 12 is mounted on the rotating shafts 11.11.
Power is transmitted via the transmission case 13. And the rotating shaft 11.11 is connected to the mounting seat 14.14 through the mounting seat 14.14.
A linear spiral cutting blade 15.15 that rotates at a substantially predetermined pitch along the virtual cylinder is fixed to the spiral cutting blade 15.15.
The tip of 15 is sharp. In the deep cultivation device having such a configuration, for example, the tractor 1 is introduced into the orchard, and the first
As shown in the figure, the deep-cultivation device is positioned at the location where the lateral roots R under the fruit tree are overhanging, and the hydraulic motor 12 rotates the spiral digging blade 15.15 in the normal rotation direction. The supporting force of the support stand 9 of the hydraulic cylinder 10 is released. Then, the spiral digging blades 15, 15 descend while the sliders 8, 8 slide along the guide rods 7, 7 due to the force of digging into the soil due to rotation and the weight of the device itself. At this time,
Ragusa Kushinba 15.15 is! It is formed by a linear body shaped like 1lltIt, and beyond that, even if jij hits the root R, it digs downward avoiding this, and the root R.
It is not easy to cut or lift a person. In addition, if the soil is hard and the helical digging blade 15.15 does not dig by itself, you may work while adding weight using the hydraulic cylinder 10. passing through,
When the mounting seat 14.14 reaches the soil surface, the digging blade 1
5 and 15 are stopped, and in this state, the support base 9 is slightly lifted by the hydraulic cylinder 10, or the entire Fukagawa device is slightly lifted by the three-point linkage mechanism 2, and the spiral digging blade 15 .15 Cracks appeared in the soil around the soil entry area and the soil was deeply plowed. Then, while avoiding reverse rotation of the hydraulic motor 12 and contracting the hydraulic cylinder 10, the spiral digging blade 15.15 is extracted from the soil. Also, Tori (=J seat 14
.. From the state where 14 has reached the surface of the soil, rotate the spiral digging blade 15.15 about 1/2 turn, and the ground resistance of the 1 seat 14.14 and the spiral digging blade 1! i, 15
It is also possible to create cracks in the soil around the area of the spiral digging blade 15.15 by the force of the spiral digging blade 15 and 15 when trying to dig, and to cause the soil to fall. In the second embodiment of the present invention shown in FIGS. 3 to 6, a heartbeat 17 is provided in the vertical direction in the medium heat section 10a at the -1-bottom of a pedestal 16 having a trapezoidal side surface. A cylinder 18 having a spline formed on the outer periphery is inserted into the outer periphery of the heartbeat 17 in a vertically movable manner, and a rotary sleeve 19 is provided with a spline formed on the inner periphery to fit with the spline on the outer periphery of the cylinder shaft 18. It is rotatably supported by a transmission case 20. The transmission case 20 extends horizontally from the upper bottom portion 16a of the pedestal, and a prime mover 21 is directly connected to this extended portion. The prime mover 21 is provided with an operating culm 22, which transmits power to the transmission case 20, that is, the rotary cylinder shaft 19, by causing the rotary cylinder shaft 19 to rotate in the normal direction when rotated in the cutting direction around the Nicotral position. When rotated counterclockwise, the rotary cylinder shaft 19 is reversely moved.A spiral cutting blade 15a similar to that of the first embodiment is attached to one end of the cylinder sleeve 18 via a mounting seat 23. is installed.In addition, one of the feelings 17
- The edges are pointed so that when the pedestal 16 is installed on a broken earth surface, it will be slightly inserted into the soil. In the deep I11 device configured in this way, the pedestal 1
When G is installed in a lifting place where the roots of a fruit tree are overhanging as shown in Figure 3, the tip of the heart 11 will be stuck into the soil, and in this state the operation lever 22 will be shown in Figure 4'. As the cylinder rotates in the S1 direction as shown in FIG. ,
The spiral drive blade 15a digs into the soil, and the rotary cylinder shaft 19 descends while rotating. Then, when the soil surface 23 reaches the soil surface, the operating rod 22 is returned to the two-coral position to stop the rotation of the spiral digging blade 15a, and the spiral digging blade 15a is rotated as shown in FIG. Further rotation in the normal direction ←l, /2 rotations or slightly lifting of the pedestal 1G causes cracks in the earth around the penetration area of the spiral digging blade 15a, causing a wide area to be dug to a depth of 1. Thereafter, as shown in FIG. 6, the operating rod 22 is rotated in the opposite direction J1 to remove the spiral digging blade 15a from the soil without reversing the direction. (Effects of the Invention) As explained above, the present invention According to deep cultivation equipment for orchards, etc., a screw and digging blade is attached to a rotating shaft set vertically, and by rotating the rotating shaft, the spiral digging blade digs deep into the soil to remove the roots of fruit trees, etc. Crush the subsoil without cutting or causing major damage, and lift it upwards with the spiral digging blade penetrating deeply into the soil, or with the screw & digging blade's mounting seat in contact with the soil surface. By rotating the spiral digging blade about half a turn, it is possible to create cracks in the soil around the area where the spiral digging blade has penetrated, allowing for deeper plowing.
