(Industrial use)

The present invention relates to a farming management work vehicle for planting crops, relieving work, etc. in a farm for planting crops such as leaf tobacco.

(Conventional technology)

Background Art [0002] Conventionally, a farming management work vehicle that travels on a field in which crops such as leaf tobacco are moved is known, having a structure in which left and right crawler-type traveling devices are connected by a door frame.

In those types of farming trucks, the attachments for planting and relief work were fitted directly to the frame.

(Problem that plan is going to solve)

By the way, in the conventional example, since the work attachment parts such as the spray nozzle for relief are directly mounted on the door frame, the attachment and removal work of the work attachment parts is difficult, and the attachment height of the attachment parts can be varied. Could not be changed.

The purpose of the present invention is to integrate the left and right traveling device into a frame frame. In the agricultural management work vehicle that is interlocked, the work attachment parts can be removed and the height position can be freely mounted.

(Means to solve the task)

In order to achieve the above object, the agricultural management work vehicle according to the present invention, the engine and the left and space travel device, the left type frame installed on the left traveling device, the right type frame installed on the left and space traveling device, In order to transmit power to the left and right space travel devices, power transmission mechanisms and work attachments installed on the left and right frame and transverse frames are mounted.

A plurality of attachment mechanisms arranged in pairs on the left type frame and the right type frame are respectively provided with different ground heights, and a supporting mechanism for supporting the work attachment parts is provided, and the supporting mechanism has a base portion of the supporting mechanism. By being fitted to the attachment mechanism, it is mounted at the required height position of the left and right vertical frames.

According to this configuration, the source of the agricultural work management vehicle selects a required position from among a plurality of mounting positions having different ground heights by a simple operation of inserting a support mechanism for supporting the work attachment part and its base portion into the attachment mechanism. It is possible to mount on. By adopting the structure that the support mechanism can be mounted at the required position from the plurality of ground heights, the result is that the ground heights of the attachment parts for work such as spray nozzles are matched with the planting and growing conditions of the crops to be managed. Adjusting can be easily realized.

In a preferred embodiment of the present invention, the engine muffler is disposed at a position higher than the attachment mechanism having the highest ground height among the plurality of pairs of attachment mechanisms.

Basically, the attachment mechanism with the highest ground height is set to be higher than the height of the crop to be managed. By attaching a muffler at a position higher than this position, the exhaust gas diffuses from the top of the crop and the exhaust gas is released from the crop. It can reduce the adverse effect on the.

In such a configuration, by placing the exhaust pipe connecting the engine and the muffler through the interior of the vertical frame, it is possible to prevent the inconvenience that the hot exhaust pipe is in direct contact with the crop and the worker.

Further, in a preferred embodiment of the present invention, the power transmission mechanism is formed as a chain transmission mechanism, the left and right frame and the transverse frame are formed of a hollow body, and a reinforcing member is built into the left and right frame. The reinforcement member may be provided with a chain of the chain transmission mechanism.

As a result, the chain tensioning device acting by the chain can be fixed to the reinforcing members of the left and right longitudinal frames, thereby preventing the longitudinal frame from deforming due to the force acting through the chain tensioning device.
