Description

[Detailed description of the invention] This invention relates to a sapling digging machine with a cutting board.

Conventionally, a sapling excavator with a digging wheel excavates a hole with a square cross section, but as it is, the soil surrounding the branches and roots of the sapling has a high holding power against the sapling, and when the sapling is pulled out, It has the drawback of damaging the branches and roots and breaking the twigs of the seedling itself.

The purpose of the present invention is to eliminate the above-mentioned drawbacks and to excavate the seedlings with ease, by attaching excavation wheels 3, 3 to rotary shafts 1a, 1b, which extend slightly to the left and right from the deceleration chamber G, respectively. In the suspended self-propelled towing J, an engine E is attached to the rear end of the support tube S that extends obliquely backward from the reduction chamber G, and a support bar 5 is attached to the support tube S slightly forward of the engine E. An earth cutting board 4 having a chevron-shaped cross section with the top at the top is attached to the lower end of the support bar 5, and the width of the bottom of this earth cutting board 4 is equal to It is formed to be larger than the width between the outer sides of the excavation wheels 3, 3, and during self-propelled towing and extraction, the lower corners of the left and right side walls excavated by both the left and right excavation wheels 3, 3 are used as the earth excavation plate. The purpose of this project is to submit a sapling excavator with an earth excavation plate that is configured to excavate soil using the following methods.

Hereinafter, one embodiment of the present invention will be explained according to the drawings.
In the figure, J is a self-propelled towing machine which is the main body of the seedling digging machine of the present invention, and is composed of an engine E, a support pipe S1, a deceleration chamber G, a handle H, etc., and extends slightly from the deceleration chamber G to the left and right. Excavation blades 2~ are attached to the rotating shafts 1a and lb which
A digging wheel 3,3 with 2 is mounted.

Ra and Rb are front and rear guide rollers rotatably supported at the front and rear of the machine, Na is a branch root of the sapling N, and Nb is a twig above the sapling N.

Next, the excavation board 4, which is the main part of the present invention, is formed into a mountain-shaped cross section with an apex upward, and is connected to a part of the support pipe S of the machine (this support pipe) through a support bar 5. It is located slightly ahead of engine E installed at the rear end of S.

) is supported. The width of the bottom of the excavation board 4 is larger than the width between the outer sides of the left and right excavation wheels 3, 3.

Next, the functions and effects of the embodiment configured as described above will be specifically explained.

Now, start the engine E of this machine and dig the digging wheel 3.
, 3, as shown in FIG. 2, the excavation wheel 3 forms an approximately rectangular section of the excavation HO, and in this example, the above-mentioned earth cutting board 4 is placed on the left and right skirt walls of the excavation HO. H1a, H
Since both lower corners of 1b can be excavated in a triangular shape, the tensile resistance of the residual soil Zn is significantly reduced, and as a result, the seedling N can be easily extracted.

That is, this is an effect unique to the present invention obtained by attaching the earth cutting board 4 of the present machine.

Now, the gist of the present invention is the structure described in the scope of the claims for registration of a utility model, and in particular, the provision of the excavated board provides the above-mentioned effects, thereby skillfully achieving the intended purpose of the present invention. Therefore, the present invention can be said to be extremely practical as a sapling excavator with a cutting board, and can be said to be a device that will greatly contribute to the horticultural industry.

Notes regarding the excavated board: (a) As shown in Figure 5, both bases Ta and Tb of the board should be connected with a stay sy.

(b) As shown in Figure 6, both bases Ta,
Tb is connected by a bottom plate Tn to form the entire shape into a triangular cylinder shape.

(C) As shown in Figure 7, both bases Ta and T
Add some relief angles Ka and Kb to b.

(d) As shown in Fig. 8, a slight receding angle Kc is attached to the side surface of the excavated board with respect to the bases Ta and Tb.
