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 injecting slurry into soil, and more particularly, when slurry is injected deep into the soil of a field, the slurry is ejected to the ground surface by pressure or the like. The present invention relates to a soil working machine for injecting slurry into soil so that the slurry is prevented from flowing down on slopes.

[0002]

2. Description of the Related Art It is widely known to promote organic agriculture by spraying and injecting the slurry into a field for the purpose of disposing of the slurry and fertilizing the soil. It is best known that the slurry in the tank is sprayed directly on the field by a pump. In this spraying operation, the slurry is only scattered on the surface of the field, and there is no guarantee that the slurry penetrates deep into the soil, and it cannot be said that the slurry is effectively used.

[0003] Further, the slurry sprayed on the surface of the field emits offensive odor, and in particular, generates a strong odor when exposed to sunlight, and is one of the bottlenecks of slurry disposal, also referred to as odor pollution. Therefore, it has been practiced to run a tank truck containing the slurry in a field, guide the tip end of an injector extending from the tank into the soil, and spray the slurry inside the soil while moving.

[0004] A typical working machine used for this operation is shown in FIG. 10 and the following, and the one shown in FIG. 10 is a so-called bakium (tank) car having a slurry pumping ability. The slurry is supplied to the slit space where the locus of the subsoiler knife is formed while pulling the subsoiler behind the subsoiler to perform the subsoil processing operation.

[0005] Fig. 11 shows a self-propelled vehicle equipped with a slurry tank. A subsoiler is mounted behind the slurry tank, and the slurry is removed from the soil while performing subsoil treatment work. It supplies deep inside.

Further, FIG. 12 shows a sub-soiler attached to the back of a bacilli car to perform a slurry while performing a subsoil crushing operation. Is supplied to the slit space.

[0007]

In any of the working machines for supplying such a slurry to a field, a subsoiler is mounted behind a bacillus car, and the subsoiler is provided in a rear view of a worker operating a tractor. At present, it is not possible to check the actual state of slurry spraying work and it is necessary to perform blind work, so to check the work, stop the tractor once and get off You can only confirm it.

[0008] In addition, a device in which a subsoiler is connected to the back of a bacium car (a bacium tank) has a drawback in that workability is poor. Therefore, a device in which a subsoiler is positioned between a tractor and a bacium car is also known. However, this is a configuration in which a bacium car is connected to a subsoiler mounted on a tractor, and the subsoiler enters the tractor driver's field of view. In particular, when working in an uphill state, the space formed by the chisel that constitutes the subsoiler becomes a downgraded tube, and the slurry may squirt onto the ground due to pressure, and the state is the same as spraying on the ground. Result. Therefore, the present invention not only improves the workability in the field, but also contributes to the effective use of the slurry, and furthermore, injects the slurry into the soil so that the injected slurry can be reliably contained in the soil. It is an object of the present invention to provide a soil working machine that performs the following.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a slurry for moving and plowing while working on soil subsoil by pulling a bacillus car. In a soil working machine for spraying, a bacium car configured by mounting a tank on a vehicle body having a tow rod,
A subsoiler disposed in front of the tank of the vehicle body, the subsoiler has a slurry injector behind a knife body, and behind the injector,
A second wing that crushes the space formed by the chisel from above is provided, and a slurry ejected from the injector is mixed with the crushed soil to increase the viscosity,
It is configured so that it does not erupt on the ground,
It is characterized in that the slurry is agitated and provided in a branch line for distributing the slurry in a pipeline from the slurry tank to the injector.

[0010]

The soil working machine for injecting the slurry into the soil according to the present invention can crush the tunnel-like space formed by the chisel of the subsoiler immediately after the slurry is ejected by the injector, so that the slurry can be transferred to the ground. In the process of supplying the slurry to the injector, a branch portion is arranged to prevent reverse jetting, and the rotary portion is imparted to the slurry at the branch portion, and is equally distributed to the left and right.

[0011]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a soil working machine to which the present invention is applied. In these figures,
Reference numeral 10 denotes a tractor, and a tractor car 20 is connected to the tractor 10 via a tow rod. The bacterium car 20 has a slurry tank 22 mounted on a vehicle body 21. In the figure, the towing rod 23 is extended.

A connecting portion 24 which can be connected to the hitch of the tractor is formed at the foremost portion of the towing rod 23. Next, a number of coaters corresponding to a subsoiler to be described later are attached. A subsoiler device 30 is attached across the rod 23 along the working width direction.

The subsoiler device 30 is constructed by attaching a chisel 32 at the lower end of a knife 31 and a wing 32a behind the knife 31.
A bracket 39b is attached to the knife 32 located above 2a so as to avoid the injector 41, and the front end of the second wing 39 is pivotally supported by a pin 39a on the bracket 39b. It can be rotated within a proper range.

[0014] A second valve located behind the injector 41
When the wing 39 is horizontal, the injector 4
The slurry, which is located at a position higher than 1 and is pumped by the pump, is stirred with the surrounding soil by the vertical movement of the second wing 39 to increase the viscosity as a whole.

The upper end of the injector 41 is connected to the slurry tank 22 via the on-off valve 25 and the flexible pipe 42 via a branch 43 which will be described later. Can be supplied to the injectors 41, 41.

The subsoiler device 30 is provided with the towing rod 23.
The upper end 31a of the knife 31 of the subsoiler is inserted into a relatively narrow space between the pair of guide plates 33a.

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

The knife 31 connected to the rod 35a is moved up and down by the expansion and contraction of the hydraulic cylinder 35, so that the knife 31 can be raised upward when moving or not working in the field. .

The knife 3 of the subsoiler device
The spacing between the working width directions 1 and 31 is 21
The interval between a and 21a, in other words, the interval is smaller than the tread, more specifically, approximately 1/3, and is symmetrically distributed around the towing rod 23 to the left and right.

The hydraulic cylinder 35 expands and contracts by receiving a supply of pressurized oil from an oil pump provided in the tractor 10. To supply a slurry to the injector 41, the port of the on-off valve 25 is moved from the tractor 10. This is done by remote selection operation.

The branch 43 has a slurry guided from the flexible pipe 42 inside the two injectors 4.
1, the distribution wall 43a is formed along the inner surface of the branch portion 43, and is temporarily increased toward the supply port 43X and decreased toward the outlet 43Y. The center of the supply port 43X is slightly lower than the center of the internal space, and a rotational motion is given inside, so that the supply port 43X is distributed to the left and right outlets 43Y.
Are symmetrical about the supply port 43X pipe, and have a substantially inverted V-shaped cross section.

A flexible pipe 44 extends from the outlet side of the branch part 43, and its end is connected to the injector 41.

Next, the actual operation using 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 bacium car 20 and the sub-soiler device located in the tow rod portion. The 30 knives 31 are guided into the soil to perform a crushing process on the subsoil.

At this time, the slurry is supplied from the flexible pipe 42 to the injector 41 through the on-off valve 25 by the output of the pump mounted on the bacilli car 20. That is, since it is moving while supplying slurry into the slit space formed by the knife of the subsoiler device,
The slurry can be buried deep in the field.

In the non-working state, the knife 31 is raised by contracting the hydraulic cylinder 35 so that the knife does not become an obstacle when moving.

In particular, the tread of the bacium
Since the knives of the sub-soiler device are mounted at intervals of about one-tenth, even if the running trajectory draws an arc, the rut of the bacium car fits into the slit formed by the knife 31 of the sub-soiler device 30. There is no trouble to work.

Further, the work is continued on the adjacent uncultivated land. The work is advanced by putting a rut of a tractor on the trail of the knife 31 formed in the first working process,
Knife 31 of subsoiler device 30 in the next operation process
The work is performed in such a state that the trajectory of the tractor can pass on the trajectory of the previous tractor (FIG. 4).

In the above embodiment, the type in which the knife of the subsoiler device moves almost vertically has been described.
The subsoiler device may be pivotally supported on a support portion so that the subsoiler can be rotated forward or backward in the working direction so as to increase the ground height.

Also, the subsoiler device 30 is
The sub-soiler device 30 is mounted by using a three-point link mechanism, and a frame 36 of the sub-soiler device 30 is provided with a hitch 37 at a rear portion thereof. The intended work can be performed by using the connecting portion 24 of the 23.

In the subsoiler apparatus 30, reference numeral 38 denotes a core disposed at a position where the knife 31 can follow.
The knife is shown so that the knife 31 can move along the slit formed by the coater 38.

In particular, in a working environment having an upslope of a wavy land as shown in FIG. 10, if there is a weak place between the space formed by the chisel 32 and the ground surface, the injector 41 moves into the soil. The supplied slurry tends to break through the weak part of the soil and squirt onto the ground surface, and if the space is sloping, it tends to be washed off downstream.
When the second wing 39 attached to 1 moves up and down around the pivot point, the slurry ejected from the injector is mixed with the soil around the space, the viscosity of the slurry is increased, and the ground surface of the slurry is increased. To prevent water from escaping into the room and spilling downstream of the space.

As is apparent from the above description, according to the soil working machine for performing slurry injection according to the present invention, since the subsoiler device is disposed immediately behind the tractor, the subsoiler device is located within the field of view of the tractor operator. Slurry can be sprayed, and the work can be performed while constantly checking the slurry injection state.Moreover, the slurry is supplied to a deep position in the soil, and after the injection, it is mixed with the surrounding soil and has a high viscosity. It does not erupt to the ground and does not cause odor, it can accelerate the decomposition of slurry and contribute to soil fertilization,
Domestic animals such as cattle are not likely to become excessively salty on the meadows where the slurry has been sprayed, and it is possible to prevent the appetite of livestock from decreasing. In addition, in the process of supplying to the injectors, the slurry is stirred and mixed at the branching portion, and the lump such as feces and straw waste is disintegrated and distributed.
