Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a power-driven tilling device that is attached to a tractor or tiller, and is capable of cultivating seeding or transplanting seedlings in one step. It creates a new and effective vent.

[Prior art]

A method is to use a tilling device or plow that has a horizontal tiller wheel that rotates from top to bottom (normal rotation) at the front to rough up the soil and crush the topsoil to create beds for growing crops; The above-mentioned method of making a veratora is used by using a tilling device having a tilling wheel with a horizontal axis that rotates (reverses) and scoops up soil at the front and releases the soil backward through the upper part. .

However, the former method requires two processes, plowing and crushing, to create the bed.
In the latter case, teeth are installed over the entire width of the tiller wheel, which requires a long process and is unreasonable. Not only that, but the topsoil also
Since fine soil is spread over the entire width, mechanically, excessive power is required, and the bed becomes extremely dry, making it unsuitable for the type of crop and field conditions.

[Problem that the invention seeks to solve]

This invention enables, in one work step, only narrow rows of widely cultivated plowing to be used for sowing or transplanting seedlings.
The weeds that were growing in the field are plowed and buried in the soil, and a layer of fine soil is created on the surface, creating an effective bed with relatively light load and less drying.

[Means to solve the problem]

In order to solve the above problem, the following tilling device is used. That is, it has a tilling wheel with a horizontal shaft that rotates in front to scoop up soil, pass it upward, and release it to the rear. The tilling device is characterized in that facing teeth are provided close to each other.

[Effect]

When this tilling device is attached to the rear of a tractor and a part of its power is transmitted to move the tilling wheel forward while rotating, the soil in front of the tilling wheel is cleared of weeds on the surface by the tilling wheel. It is scooped up along with the soil and released backward along the inner surface of the tilling cover that covers the top of it. Here, a part of the rear width of the tiller wheel is provided with teeth facing downward from the top, so weeds and large clods can be removed by the teeth. Instead of passing through the eyes of the tooth, it is guided in front of it and falls directly below, and thin soil, or soil that has been shattered by colliding with the tooth, passes through the eye of the tooth and falls on top of the above-mentioned weeds and large clods. When it rained nine months ago, these areas were buried, forming thin strips of dirt on the surface. Also, on the side, since the teeth are not close to the tiller wheel, the clod of soil is not crushed by the collision with the teeth, but falls as a relatively large clod, and weeds fall on top of it. It takes 9 minutes to finish the shape so that it covers everything.

In other words, the bet made after the tiller passes is
At the position where the tooth passed, a layer of weeds and soil clods was covered with a thin layer of soil, and on the side of it, a relatively large soil clod was pulled out and covered with slightly cut weeds. It will be in a closed state.

〔Effect of the invention〕

For this reason, not only is it possible to stably sow seeds and transplant seedlings in thin rows with the soil formed on the surface after the tooth has passed, but it is also rational because it can be removed in one step. In addition, since only the small and medium-sized areas are used for work on the frame, the load required for the work is light, and since the soil clods are large in both small and medium-sized areas, the passage of oxygen in the air is good, which is suitable for crop growth conditions. Sarada is suitable because the top is covered with weeds and provides shade, less dryness and high water retention, allowing crops to grow effectively.

〔Example〕

Next, the tilling device according to the present invention will be explained based on the attached drawings. (1) is a horizontal shaft (tilting claw shaft) that is attached to the lower ends of the left and right gear boxes (2) and the support plate (3). A tilling wheel (5) is supported and a large number of tilling claws (4) (4)... are fixed to it.
Then, receiving the tractor power from the input shaft (6),
It is made to rotate like an arrowhead.

A tilling cover (7) covers the top of the tilling wheel (5) and is fixed on the left and right sides to the inner surfaces of the gear box (2) and support plate (3). (8) (8) (8) is a piece,
3 legs, each with a protruding horizontal shaft (9) (9) (9
) 'e is provided, and is tightened with a bolt αDα1) (Ill) under the pipe 0000αO provided at the rear end of the tilling cover (7).

urU2u is formed by a plurality of rods α small α... hanging down from the horizontal rod α3α3α3 in a comb shape, each with teeth, and support rods α9α5QEfl protrude upward from the horizontal rod a3α3αa, and these rods α9α6MK is the horizontal axis (
9) (9) (9) is inserted and tooth α202■
is made to rotate around this horizontal axis (9) (91(9)).

αGα0... is a tube, and the above horizontal axis (9) (9) (9
) is inserted, the upper end of the auxiliary cover 〇n is fixed, and the auxiliary cover 〇η is made to rotate.

(To) (To) is a continuous rod, the lower end of which is pivoted to the auxiliary cover αη, the upper end of which is inserted into the frame α9, and is held in place by a spring holder (2υ).@■ (a) and (to) (a) (to) are the receiving parts, and the respective support rods α
9αθα9, projecting from the tilling cover (7) and the auxiliary cover Ql, and the respective holes (22a) (
22a) (22a) and holes (23a) (23a) (2
3a) is rotatably provided on the support rod α9α9α so that the tip of the cautery (c) (NI241) is engaged with it.

Then, when the stop #1 (2) is hung on the receiving part (a) on the tilling cover (7) side, the tooth αa rotates around the groove shaft (9), and the rod α ...is a tiller wheel (5)
When the tooth (2) is fixed close to the rear of the auxiliary cover 〇η and the cautery is hung on the receiving part (c) of the auxiliary cover 〇η, the tooth (2) rotates around the horizontal axis (9) and its The rods α along α4 are fixed to the inner surface of the auxiliary cover α apart from the tilling wheel (5). °
@@ (To) is the lever, @ (I) is the tail wheel.

The tilling device configured as described above is connected to the rear of the tractor with a 3-point link, and its PTO shaft and input shaft (6
) and are used by connecting them with a propeller shaft.

Here, for example, when making a bet to sow two rows on the left and right, place the left and right stop #J (c) (c) in the respective receivers @
Stop the hook and hang the center stopper #J1241 on the center receiver (c). Then, the left and right teeth 0'2 have their rods Q41 (14)... approaching the rear of the tilling wheel (5), and the center tooth α2 has its rod α4α... approaching the rear of the tilling wheel (5). 5) It retreats further back from the rear of 5) and moves further away from here, resulting in a state where it seems to be stuck to the lower surface of the auxiliary cover αη.

In this state, the tractor is moved forward while driving the tilling claw shaft (1). Then, the tilling device uses its tilling claws (4), (4), etc. to scoop up the soil in front of it, and discharges the soil mass along the inner surface of the tilling cover (7) to the rear. . At this time, if the field is overgrown with astragalus or early spring weeds, these weeds will be thrown backwards along with the above-mentioned soil clods, but the rods (14) Q4)... will be moved to the tilling wheel (5). On the adjacent left and right sides, without passing through the eye of this rod α4) (14)..., it is guided along the front side to the lower end, and placed in the low position of the dug groove. It is placed with a large clod of earth that could not pass the eye. On top of that, there is a thin layer of soil that passed between the rods 04α and 04α, and a thin layer of soil that was shattered by colliding with this rod 04)0(1) and narrowed and passed through this eye. will fall and fill these areas. In addition, in the center, the rod α4) (14) is far away from the tilling wheel (5) and is stuck to the auxiliary cover pouch, and the tilling cover (
7) There is almost no influence on the movement of the soil that is released backwards along the inner surface of the soil, so the soil clods and weeds that have been dug up are discharged backwards as they are.The specific gravity of the soil clods is higher than that of the weeds, and the inertia are large, so even if they are released at the same time, clods of soil will sink under the grass, making it look like the surface is covered with grass.

As a result, as shown in Figure 3, there are stripes on both the left and right sides with a flat layer of thin soil on the surface and a not-so-large clod buried beneath it, and between these there is a strip of soil that has been removed. The surface is covered with grass, and there are rows all at once with large clods of soil underneath.

If this is done well, in areas where the soil clods are large, moisture in the soil is less likely to be sucked up to the surface by capillary action, and the surface is covered with grass and shaded by sunlight, so it is less likely to dry out. Good water retention and good seedling growth.

When carrying out this invention, if the teeth are divided into a plurality of parts and adjusted individually as shown in the figure, for example, even in the case of the one shown in the figure, there is a strip in the center with a thin strip on the surface. For example, we tried to make the soil finer by going to the goldmine and making the surface finer.
It has the characteristic of being able to be used in a variety of ways and being diversified.
