Description

[Detailed description of the device] This device is attached to the front of a mobile agricultural machine such as a tractor or an agricultural transport vehicle that runs on its own in a field, and is used to spray granules, powder, etc., or sow crop seeds. This article relates to an agricultural spray vehicle that can be used for agricultural purposes.

That is, this invention relates to an agricultural spraying vehicle that allows the user to directly see the state of dispersing granules, etc. in front of the machine while operating the mobile agricultural machine, making it extremely easy to manage the work.

Conventionally, this type of agricultural spray vehicle has been attached to the front of a self-propelled mobile agricultural machine, but it has not been configured to change direction and travel in the same direction as the moving mobile agricultural machine. It could not be called an easy-to-drive agricultural spray vehicle.

In addition, there is no agricultural spray vehicle that can be reliably towed by a mobile agricultural machine and run smoothly while swinging to adapt to the unevenness of the ground surface without affecting the mobile agricultural machine being towed.

The present invention provides a front-tractable agricultural spraying vehicle that solves these problems.

That is, in this invention, a bearing tube 4 is installed vertically at the tip of an arm 2 that is supported in a protruding manner in front of the body 1 of a self-propelled mobile agricultural machine, and a vertical shaft 3 is fitted into this so as to be horizontally rotatable. Another bearing tube 5 is installed horizontally at the lower end of the vertical shaft 3, and a horizontal shaft 6 is inserted into this so as to be rotatable left and right. The gist of this invention is the structure of an agricultural spraying vehicle characterized by a hopper 10 supported by wheels 8, 8 and connected to and supported by a hopper 10 having a spraying port 9 at its bottom.

This invention will be explained with reference to the illustrated embodiment. Reference numeral 1 denotes the body of a mobile agricultural machine, and 2 denotes an arm fixed to the front of the machine body 1, protruding forward of the machine body 1 and supported substantially horizontally.

Reference numeral 3 denotes a vertical shaft, which is rotatably fitted into and supported by a bearing tube 4 provided vertically at the tip of the arm 2.

Reference numeral 5 designates another bearing tube connected to the lower end of the vertical shaft 3, which is supported substantially horizontally at right angles to the vertical shaft 3, into which a horizontal shaft 6 is fitted so as to be rotatable left and right. A joint 7 of a parallel link mechanism is provided at the rear end of the bearing tube 5 and is vertically swingable.

A hopper 10 is connected to the other end of the joint 7.

This horizontal shaft 6 and the joint 7 are opposite to the above, the vertical shaft 3 and the joint 7,
The horizontal shaft 6 may be connected to the hopper 10.

The hopper 10 is supported on both sides by a pair of left and right wheels 8, 8 that rotate independently, and a dispersion port 9 is provided at the bottom of the hopper 10.
is open.

Note that the dispersion port 9 is preferably provided with a metering mechanism for adjusting the amount of granules or the like to be sprayed.

Since this device is constructed as described above, the tip of the arm 2 located in front of the machine body 1 follows the traveling machine body 1 and moves together with the machine body 1, so that the hopper 1 supported on both sides by the wheels 8, is towed and guided by the tip of the arm 2, and can freely change direction and follow the aircraft 1 via the vertical shaft 3.

Furthermore, this hopper 10 is connected to the vertical shaft 3 via a horizontal shaft 6 that can freely rotate left and right, and a joint 7 that can freely swing up and down, so that the hopper 10 is fixed to the body 1 and is attached to the body 1. Regardless of the arm 2, which fluctuates with movement, the vehicle will travel while being towed by the tip of the arm 2, adapting to the unevenness of the ground surface.

As described above, according to the present invention, the operator can operate the machine while directly observing the working status of the hopper located at the front of the machine, which has the practical benefit of extremely easy work management and the ability to disperse granules, etc. Since the hopper follows the movement of the mobile agricultural machine, it has the practical benefit of being extremely easy to operate.

Furthermore, according to this invention, the hopper for dispersing granules, etc., oscillates to adapt to the unevenness of the ground surface, regardless of the movement of the arm tip that pulls it, and is reliably pulled to the arm tip. It has the practical benefit of being guided.
