Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a rice transplanter in which a paste tank (a fertilizer tank) for accommodating a paste-type chemical, particularly a fertilizer, is provided in consideration of the arrangement of the paste tank.

[Prior art] Rice transplanters that apply fertilizer simultaneously with rice transplantation are often used, but in this case, additives are added so that the fertilizer acts on the transplant for a long time to form a paste. Have been. Thus, this fertilizer has a rather high viscosity and has a fairly high flow resistance even with thick pipes.

In a conventional rice transplanter with a paste tank, an engine, a control space, and a seat portion are provided above a palm supported by a front wheel and a rear wheel, and a planting portion having a seedling mounting table is connected to the rear. The paste tank is mounted below an engine provided at the front of the sashimi, and is connected by a pipe to a paste pump provided at the front of the rear wheel below the seat.

[Problems to be solved by the invention]

As described above, the paste tank is located below the front of the chassis, and the paste pump is located below the seat and in front of the rear wheel.Therefore, these members are connected by a long pipe to supply the paste. There is a problem that must be. When the pipe for supplying the paste becomes long in this manner, a large head difference between the paste tank and the paste pump cannot be obtained, the resistance required for suction of the pump increases, and an accurate discharge amount is obtained until the paste tank becomes empty. You will not be able to do it.

Also, if the paste tank is filled with paste, the weight of the front of the chassis will be large, and if the paste is used, the weight of the front of the chassis will decrease, so the balance of the entire aircraft will change. There is a problem that maneuverability deteriorates.

Furthermore, since the paste tank is arranged below the engine in front of the chassis, there is a restriction due to the structure of the fuselage, and the inlet of the paste tank cannot be enlarged so that the paste can be easily filled with the paste. However, there is a problem that it takes a long time to fill the high-concentration paste into this tank.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described problems in the arrangement of the conventional rice transplanter paste tank and paste pump.

[Means for solving the problem]

In order to achieve the above object, the rice transplanter according to the present invention has an engine mounted in front of an upper surface of a chassis supported by a front wheel and a rear wheel, a steering space is provided in an intermediate portion, and a seat portion is provided in a rear portion. In the rice transplanter, a pair of fertilizer tanks are installed between the front wheel and the rear wheel, just below the left and right steps of the maneuvering space, the fertilizer tanks are connected by pipes, and a paste pump is installed behind one fertilizer tank. It is directly connected or connected by a short pipe, and the steps are configured to be freely openable / closable or detachable.

[Action]

Since the paste tank 10 is arranged in the middle part of the lower surface of the chassis 4, the distance between the tank 10 and the paste pump 11 is shortened, and the suction of the paste is facilitated.
Further, since the amount of the paste remaining in the pipe is reduced, the cleaning operation is facilitated and the waste of the paste is reduced.

In addition, the steps used by operators on both sides of the body
Placing paste tank 10 below 20, 20a facilitates the operation of filling the paste.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a side view of the rice transplanter 1, in which a planting section 3 is supported by an arm at the rear of a main body 2 so as to be able to move up and down.
An engine 5 is provided in an upper front part of a chassis 4 arranged in a horizontal direction, and a seat portion 7 is provided through a space 6 for operation. A front wheel 7 and a rear wheel 8 are provided below the chassis 4, respectively.

A paste tank 10 is disposed between the front wheel 7 and the rear wheel 8, preferably below the steering space 6, and a paste pump 11 is disposed behind the paste tank 10.

By connecting the paste pump 11 directly behind the paste tank 10 as shown in FIG. 2, a pipe for transferring the paste can be omitted. In addition, 12 is a paste feed pipe, 13 is a return pipe, 14 is an indicator, and 15 is a speed reducer.

As shown in FIGS. 3 and 4, the paste tank 10
Two pieces 10a are connected by a connecting pipe 17 as one set. A paste pump 11 is directly connected to the paste tank 10a as shown in FIG. 2 or connected using a short connecting pipe 18 as shown in FIG. Note that 11
a is a sub-tank forming the paste pump 11.

As shown in FIGS. 1 and 3, the paste tank 10 is retracted as compared with the conventional apparatus and is attached to the lower part of the control space 6 so that the paste tank 11 is attached near the front of the rear wheel 9. Can be significantly reduced.

In particular, by connecting the paste pump 11 directly to the rear end of the paste tank 10 as shown in FIG. 2, it is possible to omit the suction pipe.

With the configuration described above, the following effects can be obtained.

(A) By disposing the paste tank 10 in the middle part of the machine, preferably below the steps 20 and 20a used by the operator, the balance of the machine may change depending on the amount of paste contained in the tank 10. Absent.

(B) The pipe between the paste tank 10 and the paste pump 11 is omitted or an extremely short pipe can be used, so that the flow resistance can be minimized and the influence of the suction state due to the head difference is eliminated. Can, tank 10
The paste inside can be inhaled and discharged to the end.

(C) Since the pipe between the paste tank 10 and the paste pump 11 is omitted or shortened, the amount of paste remaining in this pipe can be reduced. Further, it is necessary to wash and discharge the remaining paste from a pipe or the like after the operation, but this operation is significantly simplified, and the paste is not wasted.

The supply port 10b is opened on the upper surface of the paste tank 10, but it is preferable that the supply port 10b be large in order to fill the tank 10 with the paste in a short time.

However, in the conventional apparatus, the supply port 10 is provided under the engine 5 below the front portion of the chassis 4.
Although it was difficult to increase b and the operability was poor, in the present invention, since the paste tank 10 can be provided below the operator's step, the supply port 10b is opened and closed using this step. Can be.

FIGS. 5 and 6 show rice transplanter 1 using special steps.
FIG. 7 is a plan view showing the left and right steps 20 and 20a of the steering space 6 in front of the seat portion 7, which can be opened and closed by providing a hinge at one end, or the upper surface of the chassis 4 as shown in FIG. Is detachably attached to a stay 21 provided on the lower surface by a fixture 22 attached to the lower surface of the step 20, 20a.

In this way, by using the openable and closable steps 20, 20a, the supply port 10a of the paste tank 10 can be opened larger than that of the conventional apparatus, and the paste with a high year can be supplied in a short time. .

Further, the lids can be omitted by using the openable steps 20, 20a as lids for the supply port 10a. Also,
Steps 20 and 20a are opened / closed or attached / detached
The opening 10a can be largely opened to prevent the paste from scattering and contaminating and corroding the machine body.

[Effect of the invention]

In the rice transplanter according to the present invention, since a pair of fertilizer tanks are mounted just below the left and right steps of the maneuvering space between the front wheel and the rear wheel, which is an intermediate part of the fuselage, the rice transplanter according to the increase and decrease of the fertilizer amount in the fertilizer tank. The balance of the machine can be stabilized without fluctuations, the fertilizer tank can be covered with steps to prevent contact and collision with obstacles, and the fertilizer tank does not hinder the driver from getting on and off.

Also, while connecting a pair of fertilizer tanks with a pipe,
Since the paste pump is directly connected or connected with a short pipe behind one fertilizer tank, fluid resistance from the fertilizer tank to the paste pump is reduced, so that fertilizer can be smoothly supplied to the pump even with high-viscosity fertilizer, and Only one series of paste pumps is required, the manufacturing cost is low, and maintenance is easy.

Further, since the step directly above the fertilizer tank can be freely opened and closed or detachable, a large supply port can be opened in the upper part of the fertilizer tank, and the work of injecting the fertilizer is easy.
