Description

[Detailed description of the invention] The present invention relates to an agricultural vehicle for fertilization, chemical spraying, seeding, etc., and more specifically, a powder discharge tool for discharging powder and granules into a field. The present invention relates to a tank which is attached to the vehicle body so as to be operable to raise and lower the vehicle body, and to store powder and granular material to be dropped and supplied to the discharge tool.

Such agricultural vehicles are designed to be able to raise and lower the granular material discharger to an appropriate height relative to the field even if the amount of sinking of the vehicle body into the field changes. There was room for improvement in the structure that provides guidance.

In other words, conventionally, the discharge device and the tank are connected by a flexible pipe, but the pipe bends unexpectedly when the discharge device goes up and down, and as a result, the powder and granules are transferred to the pipe. This makes it impossible to smoothly fall and move inside the pipe, and in some cases, there is a risk that the powder or granules may clog the inside of the pipe. Moreover, when driving on the road,
The discharge device is raised significantly to avoid contact with the ground, but at this time the pipe is bent at a steep angle in some parts, which may cause premature damage to the pipe. It was hot too.

The present invention has been developed in view of the above circumstances, and its purpose is to modify the powder guide structure from the tank to the powder discharge tool, so that it can be used regardless of the lifting and lowering of the powder discharge tool. The object is to be able to supply powder and granular material appropriately and to be able to use it satisfactorily for a long period of time.

The present invention is characterized in that, in the above-mentioned agricultural vehicle, a powder guide pipe which is expandable and retractable and is biased toward the contraction side is provided between the discharge device and the tank.

Next, the effects of the feature configuration of the present invention will be described.

In other words, the powder guide pipe provided between the discharge tool and the tank always remains in a straight line or a state close to it regardless of the elevation of the discharge tool due to its expansion/contraction function and the function of returning the force after being shortened. Therefore, it is possible to guide the powder to fall and move smoothly regardless of the elevation of the dispensing tool, and it simply expands and contracts due to its inherent expansion and contraction function as the dispensing tool moves up and down. Because it is made of solid wood, there is no need to apply excessive force as the dispensing device moves up and down, and it will not be damaged prematurely. It is now possible to always perform the process accurately and satisfactorily over a long period of time regardless of whether the ejector is raised or lowered.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in Figs. 1 and 2, a passenger vehicle body is provided with a pair of left and right front wheels 1, 1, a pair of left and right rear wheels 2, 2, a driver's seat 3, etc., and the vehicle body moves laterally in a constant stroke. Equipped with a sloped seedling platform 4, a plurality of planting claws 5 for taking out and planting one seedling at a time from the lower end of the pine-shaped seedlings W placed thereon, and a plurality of floats 6 for leveling the mud surface. The seedling planting device 7,
The upper and lower swing links 8a and 8b are pivotally connected to the rear end of the vehicle body and are pivotally connected to the rear end of the vehicle body. Furthermore, a hydraulic cylinder 10 for lifting and lowering the seedling planting device is provided, so that the seedling planting device 7 can be lifted and lowered relative to the vehicle body in order to adjust the planting depth and avoid contact with the ground when driving on the road. Moreover, in order to maintain the seedling planting device 7 in a position parallel to the mud surface with the float 6, the seedling planting device 7
This is a riding-type rice transplanter that can roll freely against the vehicle body.

As shown in FIGS. 1 to 3, grooves U for fertilization are formed on the lateral sides of the seedling planting area by each of the planting claws 5.
A trencher 11 which also serves as a fertilizer release tool is connected and supported to the seedling planting device 7, and a leveling plate 12 for filling the groove U after fertilizer is supplied is attached to the trencher 11. A tank 13 having a U-shape in plan view for storing powdery fertilizer to be dropped and supplied to the trencher 11 is attached to the rear of the vehicle body surrounding the driver's seat 3.
A spiral body 16 is provided to gather the fertilizer inside the tank to a plurality of discharge ports 15 on the rear end side of the tank, and a rotary body 17 for dispensing fertilizer having a concave portion 17a for entering the fertilizer in the circumferential portion is attached to the discharge port 15 portion. and furthermore,
The fertilizer fed out from the rotating body 17 is transferred to the furrower 11.
A pipe 18 is provided to guide the vehicle, so that seedling planting and fertilization can be performed simultaneously as the vehicle progresses.

A lid 13A that opens and closes the upper part of the tank 13,
It is provided so as to be swingable to open and close, so that powdery fertilizer stored in a container such as a bag can be loaded into the tank 13.

As shown in FIG. 3, the fertilizer guide pipe 18 provided between the tank 13 and the furrower 11 is constructed by a coil spring that biases the elastic bellows-shaped hose 18A to shorten it. 18B is fitted on the outside, and it can be used to raise and lower the seedling planting device 7,
In other words, regardless of whether the groove cutter 11 is raised or lowered, the pipe 18
by keeping it in a straight line or close to it,
It is designed so that powdered fertilizer can always fall and move smoothly.

Next, another embodiment will be described based on FIGS. 4 and 5.

That is, the seedling planting device 6 includes the fertilizer delivery rotary body 2.
1 and an auxiliary tank 22 connected to the trencher 11 by a pipe, and the auxiliary tank 22 and the fertilizer storage tank 24 installed on a safety frame 23 covering the upper part of the driver's seat 3 are described in the above embodiment. It is connected by a pipe 25 having the same configuration as the pipe 18. To configure the tank 24, the tank 24 is pivoted about the horizontal axis Y at the rear end so as to be vertically swingable between an upright position for supplying fertilizer and a reclined position for loading fertilizer. Stopper 2 that receives and supports 24 in both standing and falling positions.
6, a swing-type lid 24A that is provided with a fixing pin 27 and that opens and closes a portion corresponding to the front end of the tank 24 in the fallen position, and a fertilizer storage bag A made of paper or the like that can be pushed into the tank 24. A blade body 28 is provided that cuts the fertilizer into an opening for taking out the fertilizer when the fertilizer is pushed into the tank.

The present invention can be applied not only to fertilization but also to chemical spraying and seeding, and the tank 13 or 24,
In addition to being equipped with a rice transplanter, the powder discharger 11 may be installed in a dedicated machine for fertilizing, spraying chemicals, or sowing seeds.

Further, as the powder guide pipe 18, various configurations can be used, such as one constructed by connecting a plurality of telescopic pipes in which a pair of pipe parts with different diameters are slidably and telescopically fitted together. As described in the embodiment, by using the bellows-shaped hose 18A, the cost increase of the pipe 18 can be suppressed, and due to its flexibility, for example, as described in the embodiment, the discharge tool 1 can be
It may also be advantageous to allow rolling if the vehicle 1 rolls against the vehicle body.
