Description

[Detailed description of the invention] This invention is a packet dump device that is attached to the rear of the rotary of a tractor cultivator, and is convenient for storing soil cultivated by the rotary, transporting and discharging it to a depression in the field, and leveling the land. Regarding.

Conventionally: Field leveling is generally done by using a shovel and a wheelbarrow to transport and eject mud into depressions to make it flat.

It is clear that such manual work is inefficient, and on the other hand, mechanical land leveling equipment can only level the ground partially, scraping away the mounds of mud, and
It was impossible to carry this to a distant depression and bury it.

This idea aims to mechanize the conventional manual labor of collecting, transporting, and removing mud by using a tractor tiller, and aims to provide a packet dump device that is extremely convenient for field leveling work. shall be.

The present invention will be explained below based on embodiments shown in the drawings.

FIG. 1 is a side view of a tractor cultivator 1 equipped with a packet dump device according to the present invention, and shows a power transmission section 2 having a built-in sprocket chain etc. for rotating and pivoting a rotary 2.
a is connected to the link mechanism 10.

The link mechanism 10 includes a first
a link L-1, a second link L-2 pivoted below the first link L-1, and a second link L-1,
It consists of a third link L-3 which is pivotally attached by connecting the tip of L-2, and the second link L-2 is longer than the first link L-1.

Reference numeral 3 denotes a packet located at the rear of the rotary 2, which is formed to be approximately equal in length to the width of the rotary 2, and has openings at the front and two sides to accommodate soil that is scattered backward during plowing work.

This packet 3 is connected to the third link L-3 together with the power transmission section 2a by a connecting rod 4.

The connecting rod 4 is composed of a horizontal rod 11 that connects to the third link L-3 and a vertical rod 12 that is pivoted to the rear end of the horizontal rod 11 and is used to attach a tail wheel, etc.; A support rod 13 for 3 is detachably attached to support the packet 3 in a slidable manner by means of a pin 5.

It is preferable that the pin 5 is positioned in front of the center of gravity of the packet 3, and the bucket l-3 is configured so that a clockwise rotational force is applied by the moment due to its own weight.

The support rod 13 is provided with a stopper 14 for holding the packet 3 horizontally, and the suspension support for the packet 3 is configured to be supported at two points on both sides thereof.

FIG. 3 schematically shows how the link mechanism 10, the horizontal rod 11, and the power transmission section 2a are connected, and the horizontal rod 1
1 and the power transmission section 2a are both integrally connected to a midway portion of the third link L-3.

Here, if the rear end of the horizontal rod 11 is pushed upward, the first
The second links L-1 and L-2 rotate around the pivot point with the tractor cultivator 1, and the third link L3 rotates accordingly.

In this case, since the pivot point J between the horizontal rod 11 and the power transmission section 2a of the third link L-3 is provided in the middle of the third link L-3, the movement trajectory of the pivot point J is is the first. Second
It has a substantially elliptical shape based on the difference in length between links L-1 and L-2.

Therefore, due to the rotation of the power transmission section 2a and the horizontal rod 11, the center of the rotary 2 and the rear end of the horizontal rod 11 similarly draw a substantially elliptical trajectory.

Further, the packet 3 is constructed by loosely fitting a pin 9 into an elongated hole 8 at the tip of an arm 7 whose base end is pivoted to a mast 6 erected at the rear of the cultivator 1 so as to be able to move up and down. Concatenate.

The pin 9 is provided at the front of the packet 3 and slightly lower.

The length of the elongated hole 8 at the tip of the arm 7 into which this pin 9 loosely fits is:
As shown in FIG. 2, the length is such that the packet 3 simply rises horizontally in parallel from the plowing position A1 of the rotary 2 to the ascending conveyance position A2.

In the process of the rotary 2 rising further upwards from the point A2 and reaching the traveling device A3 which does not hinder the running of the tiller 1, the front part of the packet 3 contacts the rear end of the elongated hole 8 with the pin 9. As a result of being pushed backward, the packet rotates forward about the pin 5, which is a suspension fulcrum, and performs a so-called dumping operation.

That is, since the horizontal rod 11 draws a substantially elliptical trajectory as described above, the packet 13 connected to the horizontal rod 11 similarly rotates while drawing a substantially elliptical trajectory.

On the other hand, since the arm 7 rotates in an arcuate trajectory around the pivot point with the mast 6, the length of the arm 7 is such that the trajectory of its tip intersects with the rotation trajectory of the pin 9 of the packet 3 and the pin If the locus of 9 is set to be farther away from the tractor cultivator 1, the end wall of the elongated hole 8 of the arm 7 can push the pin 9 and cause the packet 3 to roll as described above.

According to this invention, the packet 3 attached to the rear of the candle 2 of the tractor cultivator 1 is suspended horizontally when the rotary tiller 2 is tilling, so that the tilled soil scattered backward is collected at the same time as tilling.

Therefore, while cultivating the field shallowly, the cultivated soil is collected in the rear packet 3 without being scattered backwards, so that the field can be made flat.

On the other hand, if there is a deeper recess than that, the rotary 2 is pulled up to position A2, which is slightly elevated above the ground, and the packet 3 is moved horizontally in parallel upwards accordingly.
By transporting the candle 2 in this state and then further raising it to the traveling position A3, the packet 3 rotates forward as described above, and the soil contained in the packet is discharged into the recess. Can be soiled.

The earth dumped into the depression can be easily leveled by hand.

In this way, the packet 3 suspended behind the rotary 2
However, since the horizontal lifting movement and dumping operation are performed in response to the rising movement of the rotary 2, work such as removing soil from a convex part of the field and transporting it to a concave place in a distant place and discharging the soil is also possible. It is easy to do, and the ground leveling work can be done extremely efficiently.

In addition, since it is possible to collect only shallowly on the fertile surface layer of the field,
This has the advantage of being easy to use as soil for seedlings.
