The present invention relates to a three-wheeled working chair for crop management that can effectively work while cultivating crops such as grapes and moving the furrow laterally while the worker is sitting on a chair regardless of the inclination of the plantation. To improve work efficiency.

In general, farmland is formed in the open field or plastic house, so that the planting and cultivation of crops are made on the land, so the farmland is not flat and there are many slopes. In addition, the cultivation management and harvesting of grapes, tomatoes, strawberries or melons, such as the worker should always bend the waist in a standing state, causing back pain and aggravated fatigue, there was a problem of low work efficiency.

In order to solve this problem, "Purpose of improved agricultural work" of Utility Model Publication No. 0112544 (April 09, 1988) is to raise and lower the seat according to the worker's body type or the height of the crop to control the height of the harvest. There is a known technology that makes it easy to carry out work and that it is easy to carry around before and after work. The "furrow work car" of Korean Patent Laid-Open Publication No. 1999-0040466 (1999.06.05) is to allow the worker to move to the left and right while sitting, and to move the left and right to the lower part of the chair where the worker can sit. By installing the wheels to be comfortable, the worker is sitting on the chair to work and then push the left and right directions using both feet, the movement is possible, the technology is provided with a height adjustment and a rotatable connection means of the chair. The prior art relates to a working chair capable of managing agricultural products while moving for elderly or women who are weak in power, but the working chair is not disclosed to adjust the working chair horizontally according to the inclination of the crop plantation. . Therefore, the work on the slope has a problem that the work fatigue is added to the lower body and the spine in order to maintain the horizontal.

The present invention has been made in order to solve the above problems, regardless of the inclination of the plantation is always possible to work in a horizontal state to increase the work efficiency, while working without effort to move while sitting on the load of work The purpose is to reduce. In order to achieve the above object to adjust the horizontal by adjusting the height of the transfer block and the sub-frame 20 coupled to the transfer block and the transfer block coupled to the screw bar 16 having a height adjustment function. In addition, a height adjustable seat (seat), lightweight body running wheels (13) (13 '), the directional wheel 14 and the work chair consisting of a backrest is provided.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a working chair according to the present invention, showing the overall configuration of the present invention, Figure 2 is a rear view of the working chair of the present invention and a removable state of the sheet, Figure 3 is a bottom view of the working chair of the present invention. 4 is a state diagram of a work chair in a furrow flat according to the present invention, and FIG. 5 shows a state diagram of a work chair in a slope of a furrow according to the present invention.

In the working chair 1 of the present invention, the main frame 10 and the subframe 20 having the tilt control device are configured to be connected at right angles to the central portion of the main frame 10. The bottom of both ends of the main frame 10 are coupled to the driving wheels (13, 13 ') to the horizontally coupled to the ∩ type connector, respectively, and installed in the center of the main frame 10 inclination control device for adjusting the inclination do. Sub-frame 20 is coupled to the directional wheel (14) in the bottom end of the lower end coupled to the 구 type connector and coupled to the transfer block 19 on the opposite end of the plurality of guide bars (15) installed on the main frame (10) (15 '). In addition, a seat for sitting and working on the upper surface of the subframe 20 is provided.

The inclination control device is composed of a plurality of guide bars 15, 15 ', screw bar 16, the handle 17 and the transfer block 18. The actuation mechanism for horizontal holding of the sheet 32 on the inclined surface includes a plurality of guide bars 15 and 15 ′ connected to the main frame 10 and a screw bar 16 supported on the guide bar and the main frame 10. When the screw bar 16 moves up and down by operating the handle 17 attached to the end of the head), the subframe 20 moves up and down by the transfer block 18 engaged with the screw bar 16. do. Therefore, the horizontal of the sheet 32 installed in the subframe 20 is to increase the subframe 20 if the furrow of the portion where the direction control wheel 14 is located, and vice versa to lower the subframe 20. That is, the inclination adjusting means is rotated by the screw bar 16 connected to the handle when the handle 17 while the worker is seated on the chair to raise and lower the transfer block 18 engaged therein, wherein the As the subframe 20 coupled to the transfer block 18 moves up and down, the main frame 10 portion of the driving wheels 13 and 13 'is fixed, and the subframe 20 moves up and down. The direction control wheel 14 located on the inclined furrow side adjusts the level of the sheet 32 to suit the degree of inclination while moving up and down.

The height adjusting device of the seat 32 is composed of a sheet screw bar 25 coupled to the sheet coupling plate 22 and a bolt hole 27 formed in the subframe 20 so that the sheet screw bar 25 is engaged. . The driving wheels 13, 13 ′ and the direction adjusting wheel 14 may be made of any synthetic resin material or metal material, and in the case of the metal material, the driving wheels 13, 13 ′ and the direction adjusting wheel 14 may be covered with a polyurethane material. In addition, the surface of the wheel that is in contact with the arable land is preferably made of a soft material that does not damage the crops for crop management or crops while driving. The wheels are equipped with bearings for smooth running. In addition, the braking tool 30 is installed on the X-shaped connector that connects the direction control wheel 14 laterally to the front end of the subframe 20 to perform a brake function of the working chair to safely work in a stopped state on a slope. To do this.

The backrest 31 is coupled to the upper portion of the plurality of guide bars 15, 15 'to serve as a backrest of the operator to work in a more comfortable state.

And, the height adjusting means of the sheet 32 is a bolt hole (27) is formed in the subframe 20, the seat screw bar 25 is coupled to the sheet coupling plate 22 when the operator rotates in the seat sitting state The height is adjusted while moving up and down around the center so that it can be adjusted according to the body shape of the worker.

The work chair 1 of the present invention configured as described above has a work chair horizontally adapted to the inclination of a field formed in an open air or a plastic house by using a light weight material, thereby allowing smooth movement and inclination adjustment function even when the work is inclined. By adjusting and using, the worker is characterized in that it is configured to minimize the load applied to the waist or lower body according to the work.

Working chair (1) of the present invention was invented in view of the rural workforce composed of the majority of the weak elderly, the working chair (1) made of a lightweight body can work in a comfortable state can prevent fatigue and musculoskeletal diseases. It is easy to move in inclined furrows, and it is possible to work in a level state by providing a tilt control function. In addition, the sheet 32 can be adjusted up and down to fit the body shape of the worker, it is possible to easily manage and harvest agricultural products while moving to the left and right in a sitting state.
