Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soil working machine for spraying slurry, and more specifically, it is capable of spraying slurry deep in the soil of a field to perform slurry treatment and organic cultivation. TECHNICAL FIELD The present invention relates to a soil working machine for spraying a slurry for facilitating the formation of a suitable field.

[0002]

2. Description of the Related Art It is widely known that organic farming is promoted by spraying this on a field to dispose of the slurry and fertilizing the soil. As a means for that, a slurry tank is pulled by a tractor. It is the best known that the slurry in the tank is sprayed directly to the field by the pump. In this spraying operation, the slurry is only scattered on the surface of the field, and there is no guarantee that it will penetrate deep into the soil, so it cannot be said that the slurry is being effectively used.

The slurry scattered on the surface of the field gives off a bad odor, and particularly when exposed to sunlight, it produces a strong odor, which is also called odor pollution, and is one of the bottleneck of slurry disposal. Therefore, it has come to be practiced to run a tank car containing the slurry in a field, guide the tip of an injector extending from the tank into the soil, and spray the slurry inside the soil while moving.

A typical working machine used for this work is shown in FIG. 6 and subsequent figures, and the one shown in FIG. 6 is a so-called bakium (tank) car having a slurry pumping ability. Then, while pulling the subsoiler behind the subsoiler to perform the subsoil treatment work, the slurry is supplied to the slit space formed by the locus of the subsoiler knife.

Further, the one shown in FIG. 7 is a self-propelled vehicle equipped with a slurry tank. A subsoiler is attached to the rear of the slurry tank so that the slurry is soiled while performing subsoil treatment work. It supplies deep inside.

Further, the one shown in FIG. 8 is for performing subsoil crushing work together with soil preparation work, and a subsoiler is attached to the rear of the burkeum car to perform slurry subsoil while performing subsoil crushing work. Is configured to be supplied to the slit space.

[0007]

In all of the working machines for supplying such a slurry to a field, a subsoiler is attached to the rear of the vacuum car, and the subsoiler is in the rear view of the operator who operates the tractor. It is not possible to check the actual state of the slurry spraying work without entering, and it is the current situation that we are forced to perform blind work.To confirm this work, stop the tractor operation and then get off the vehicle. There is no way but to confirm.

Further, since a subsoiler connected to the back of a vaccum car (vacuum tank) has a drawback in that workability is poor, there is also known a structure in which the subsoiler is located between the tractor and the vaccum car. However, this is a configuration in which the vaccum car is connected to the subsoiler attached to the tractor.The subsoiler can be seen by the tractor operator, but the distance between the subsoilers arranged in the working width direction and the vaccum -Since the relationship with the rut was not taken into consideration at all, there was a case in which the wheels of the vacuum car fell down in the slit formed by the subsoiler during the work in the field, making it impossible to run. Therefore, an object of the present invention is to provide a soil working machine for spraying slurry, which can contribute to effective use of the slurry as well as improving workability in the field.

[0009]

In order to achieve the above-mentioned object, the present invention is a slurry in which a barium carcass is towed to perform work on the soil subsoil, and a mobile plowing is performed while spraying the slurry. In a soil working machine for spraying, a vaccum car constituted by mounting a tank on a vehicle body having a tow rod,
In a soil working machine provided with a subsoiler arranged in front of a tank of the vehicle body, at least two subsoilers are arranged in the working width direction with the towing rod as a center, and
The distance between the sub-soilers of the book is set to be less than half of the tread of the vaccum car, and the sub-soilers are configured so as to be able to ascend to obtain a ground clearance. On the other hand, a bachium car is connected to a subsoiler working machine mounted via a three-point link via a connecting rod, and at least two subsoilers are arranged in the working width direction around the connecting rod, and the distance between the two subsoilers is large. Is characterized in that it is defined to be less than half of the tread of the above-mentioned Bakiumcar.

[0010]

In the soil working machine for spraying slurry of the present invention, since the subsoiler is located between the tractor and the vaccum car, there is the subsoiler in the field of view of the operator on the tractor, It is possible to perform the work while always confirming the subsoil treatment and the slurry supply state, and it is possible to contribute to the continuity of the work because the wheel of the vacuum car does not fit into the slit formed by the subsoiler.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A soil working machine adopting the present invention will be described below with reference to the accompanying drawings. In these figures,
Reference numeral 10 indicates a tractor. A tractor bar 20 is connected to the tractor 10 via a tow rod. The tractor bar 20 has a vehicle body 21 on which a slurry tank 22 is mounted, and a front end portion of the vehicle body 21. The tow rod 23 is extended.

A connecting portion 24 that can be connected to the hitch of the tractor is formed at the foremost portion of the tow rod 23, and then a number of corrugators corresponding to a subsoiler described later are attached to the tow rod. A subsoiler device 30 is attached across the rod 23 along the working width direction.

The sub-soiler device 30 comprises a knife 31 and a chisel 32 attached to the lower end thereof.
An injector 41, which receives the slurry supplied from the slurry tank 22, is attached to the knife 32.

The injector 41 is connected to the flexible pipe 42 through the slurry tank 22 and the opening / closing valve 24, and the slurry can be supplied to the injector by driving a pump (not shown).

The subsoiler device 30 includes the tow rod 23.
It is supported by the support portions 33 arranged on both sides of the sub-soiler, and the upper end portion 31a of the knife 31 of the subsoiler is inserted into the relatively narrow space of the pair of guide plates 33a.

A hydraulic cylinder 35 is supported by a cylinder supporting portion 34 extending upward from the supporting portion 33, and the rod 3 extending from the hydraulic cylinder 35.
5a is connected to an extending portion 31b protruding from the upper end portion 31a of the knife 31.

The extension and contraction of the hydraulic cylinder 35 causes the knife 31 connected to the rod 35a to move up and down, and the knife 31 can be lifted upward during movement or non-work in the field. .

Then, the knife 3 of the sub-soiler device
The distance between 1 and 31 in the working width direction is the wheel 21 of the vacuum car.
The distance between a and 21a, in other words, smaller than the tread, more specifically, set at an interval of about one-third, and is symmetrically distributed to the left and right around the tow rod 23.

The hydraulic cylinder 35 expands and contracts in response to the supply of pressure oil from the oil pump of the tractor 10. To supply slurry to the injector 41, the port of the opening / closing valve 24 is moved from the tractor 10. It is performed by selecting and operating remotely.

Next, the actual operation of the soil working machine according to the present invention will be described. In a predetermined field, the sub-soiler device 30 is lowered to the work position by the extension of the hydraulic cylinder 35 to start the work, and the tractor 10 pulls the bucium car 20 and is located in the tow rod part. A knife 31 of 30 is introduced into the soil to crush the subsoil.

At this time, the slurry is supplied from the flexible pipe 42 to the injector 41 through the on-off valve 24 by the output of the pump mounted on the vacuum tank 20. That is, because it is moving while supplying the slurry into the slit space formed by the knife of the sub-soiler device,
The slurry can be buried at a deep position in the field.

In the non-working state, the hydraulic cylinder 35 is contracted to raise the knife 31 so that the knife does not interfere with the movement.

In particular, almost 3 of the treads of Bakiumcar
Since the knives of the sub-soiler device are attached at intervals of about one-third, even if the running locus draws an arc, the rut of the vacuum carer fits into the slit formed by the knife 31 of the sub-soiler device 30. It does not interfere with the work.

Further, the work is continued for the adjacent uncultivated land, but the knife 3 of the sub-soiler device 30 in the next work process is added to the rut formed in the first work process.
Work is performed in a state in which the locus of No. 1 can pass (Fig. 4).

In the above-mentioned embodiments, the sub-soiler apparatus has a knife moving in a substantially vertical direction.
It is also possible to pivotally support the sub-soiler device with respect to the support part so that it can rotate forward or backward in the work advancing direction so as to gain ground clearance.

Further, the subsoiler device 30 is replaced with a vacuum
Although the example provided on the side is shown, the sub-soiler device 30 is mounted by using a three-point link mechanism, the frame 36 of the sub-soiler device 30 is provided with a hitch 37 at the rear portion, and the hitch rod of the bakium car 20 is attached to this. 23 can be connected to perform a desired work.

In the sub-soiler device 30, reference numeral 38 is a cord arranged at a position which the knife 31 can follow.
The knife 31 can be moved along the slit formed by the filter 38.

[0028]

As is apparent from the above description, according to the soil working machine for spraying slurry of the present invention, since the sub-soiler device is arranged immediately behind the tractor, the tractor operator can see the field of view. Slurry can be sprayed, and the work can be done while constantly checking the slurry spraying state. Moreover, since the slurry is supplied and sprayed deep into the soil, it does not cause a bad odor and accelerates decomposition. It can contribute to soil fertility, and livestock such as cattle can be prevented from having an excessive appetite in the pasture where the slurry is sprayed, and the appetite of livestock can be prevented from decreasing.
