Description

  The present invention relates to a handle device of a tea garden management machine (a handle attached to a leg frame and provided detachably) that is effective when the tea garden management machine is mounted on a vehicle or operated (work).

  Small tea garden management machine (tea garden management machine) is a structure that can be used even on an inclined tea garden up to approximately 20 degrees, and is ideal for many tea gardens that are cultivated in mountainous areas in Japan and other countries. It is. In this tea plantation in the mountainous area, a tea garden management machine is loaded on a normal truck (for example, a 2t car, a truck), travels along a small mountain road, and is lowered from the normal truck for use.

  Therefore, in order to mount the tea garden management machine on the floor surface of the truck bed, the operator uses a pair of slope plates (in the case of a pair, one will be described). One side of the slope plate is hung on the floor surface (height is approximately 65 cm to 85 cm) of the loading platform, and the other side is grounded to the ground. That is, the tea garden management machine goes up on the inclined slope plate in an oblique state from the ground to the floor surface. At this time, for the sake of safety, one worker (one person) stands on the crawler running part side of the truck, and another worker (another person) checks whether the crawler does not protrude (cannot be removed) from the slope plate. It is necessary to visually recognize and communicate the situation (while confirming safe movement) to one person. As a result, at least two workers are required.

  As described above, when the tea garden management machine is mounted on the floor of the truck bed, the operation handle (handle device) of the conventional tea garden management machine is fixed above the leg frame and the height of the leg frame is increased. Since the length (standing) is long, the operation handle has a structure provided at a position higher and away from the operator. Therefore, it is considered difficult to operate the tea garden management machine, and particularly troublesome for a person having a small body such as a height.

  On the other hand, in recent years, cultivation in the mountainous area has been increasing year by year because it has better quality and commercial value than the temperature difference with tea trees and the elements such as clean air. . For this reason, tea garden management machines are often carried into this area. At present, tea gardens are being created even in mountainous areas where trucks cannot enter. In these tea gardens, the workers are performing manual management of various types of tea trees, resulting in poor productivity. Therefore, a small tea garden management machine proposed by the present applicant (tea garden management machine of the present invention) that can be mounted on a light vehicle to be put in this mountainous area is awaited.

  On the other hand, the revitalization of the mountain and mountain tea industry leads to the revitalization of agriculture in the entire region, and not only the economic aspects of local farmers are improved, but also in terms of daily life, local elementary schools, roads, farm roads, waterways, It is useful for maintaining bridges, meetinghouses, public halls, etc. In addition, in terms of the natural environment, it also affects the preservation of forests, cultural aspects, and inheritance of traditional festivals and traditional performing arts. It is said that it contributes to the region by improving administrative services due to increased tax revenues. However, at present, it is economically difficult to develop a road leading to a mountain-mountain tea plantation, so there is a great expectation for a tea plantation management machine that can be transported by the currently used light vehicle. By developing a light vehicle transport type small tea plantation management machine and a movable (detachable) handle device and establishing a cultivation technique corresponding to it, it is possible to improve work efficiency, reduce workload, and increase the scale. It can contribute to the management improvement of local tea industry, the development of leaders, and the maintenance and revitalization of mountainous villages.

  In view of the above, the present invention has a structure in which the length of the crawler of the tea garden management machine is substantially the same as the floor width of the loading platform of the light vehicle and the height of the leg frame is set short in order to ensure safety. And Thereby, in this invention, when mounting a tea garden management machine on the floor surface of a loading platform, it is possible to work smoothly and safely by a work such as depressing a slope plate and turning without changing the direction.

  In addition, the present invention, when mounted on a light vehicle alone by an operator, walks while operating the operation handle without getting on the driver's seat. The handle position is high and difficult to operate. Therefore, when the vehicle is mounted on the vehicle, the above-mentioned problem can be solved if the handle position is moved and fixed in advance and work is started. At this time, since the emergency stop switch provided in the tea garden management machine proposed by the applicant is equipped, the tea garden management machine climbs the slope plate and hits the light vehicle automatically when the emergency stop switch hits. Provided is a handle device having a structure in which a machine stops and can be safely operated alone. It should be noted that even when the operator makes the tea garden management machine unload from the light vehicle, it is easy to operate the operating handle without getting on the driver's seat.

  Further, another object of the present invention is that a light vehicle is usually mounted on this light vehicle considering that the height of the loading platform is approximately 65 cm as described above and the height of the leg frame is short. In this case, one worker can stand on the side of the slope plate and see if the crawler protrudes from the slope plate (confirm safe movement) while operating the tea garden management machine. A handle device is provided.

  As a prior invention, there is JP-A-11-253030 as a structure for adjusting the height of a waist handle (53) of a tea garden management machine. The present invention is a structure for adjusting the height of the waist rest handle (53) using the knobs (51) and (52) for height adjustment provided on the waist rest handle (53). It is considered insufficient to achieve the objectives of the present invention.
