[0029] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0030] like Figure 1 and 2 As shown, the agricultural mobile stool includes a seat body 1 and a frame 6. The seat body 1 and the frame 6 are connected by a lifting rod 5. The fixed end of the lifting rod 5 is fixedly connected to the frame 6, and the telescopic end of the lifting rod 5 is fixedly connected to the seat body 1. Two sets of moving wheels 8 are fixed at the bottom of the frame 6. The frame 6 and the moving wheels 8 are connected by a flexible steering mechanism 9.

[0031] like Figure 3 , 4As shown in FIGS. 5, 6 and 7, the flexible steering mechanism 9 comprises an upper mounting seat 91, a lower mounting seat 92, a bolt 93, a second nut 94, an upper supporting bowl 95, a lower supporting bowl 96, an upper rubber ring 97, a lower rubber ring 98 and a supporting column 99. The upper mounting seat 91 is fixed on the bottom of the frame 6. The bolt 93 is arranged on the upper mounting seat 91. The second nut 94 is arranged on the bolt 93. The upper supporting bowl 95, the upper rubber ring 97, the lower mounting seat 92, the lower rubber ring 98 and the lower supporting bowl 96 are sequentially arranged on the bolt 93 from top to bottom. The upper supporting bowl 95, the upper rubber ring 97, the lower mounting seat 92, the lower rubber ring 98 and the lower supporting bowl 96 are all provided with through holes matched with the bolt 93. The lower side of the upper supporting bowl 95 and the upper side of the lower mounting seat 92 are both provided with upper grooves matched with the upper rubber ring 97. The upper grooves can limit the upper rubber ring 97. The upper side of the lower supporting bowl 96 and the lower side of the lower mounting seat 92 are both provided with lower grooves matched with the lower rubber ring 98. The lower grooves can limit the lower rubber ring 98. The lower mounting seat 92 is provided with the inclined supporting column 99. The supporting column 99 and the bolt 93 form an acute angle. The top of the supporting column 99 is a supporting hemisphere. The upper mounting seat 91 is provided with a supporting hemisphere groove matched with the supporting hemisphere. The supporting hemisphere can rotate in the supporting hemisphere groove. The supporting hemisphere groove is fixed with a supporting cap 90 matched with the supporting column 99. The top of the supporting column 99 and the supporting cap 90 have a rotating gap. Specifically, the flexible steering mechanism 9 adopts the moving wheel structure of the slide plate. When turning, the downward pressure on the turning side is increased. The bolt 93 and the lower mounting seat 92 are matched with a gap. The upper supporting bowl 95 extrudes the upper rubber ball 97. The lower supporting bowl 96 extrudes the lower rubber ball 98. After the deformation of the upper rubber ball 97 and the lower rubber ball 98, the bolt 93 is deflected relative to the lower mounting seat 92. When the user sitting on the seat body 1 turns to the side needing to turn, the downward pressure on the turning side is increased. Then, the angle between the bolt 93 and the lower mounting seat 92 is changed. The upper supporting bowl 95 and the lower supporting bowl 96 extrude the upper rubber ball 97 and the lower rubber ball 98 respectively. The bolt 93 moves to the turning side relative to the lower mounting seat 92. However, due to the fulcrum effect of the supporting column 99 and the upper mounting seat 91, the lower mounting seat 92 rotates to the turning side relative to the upper mounting seat 91. In this process, the upper rubber ball 97 and the lower rubber ball 98 are partially deformed on the rotating circumference, so as to realize the rotation of the lower mounting seat 92 driving the wheel shaft 82.

[0032] The front end of the seat body 1 is provided with a storage frame 10. The back of the seat body 1 is fixed with a back basket 7. The storage frame 10 and the back basket 7 are metal mesh baskets or plastic mesh baskets. The storage frame 10 and the back basket 7 can place agricultural auxiliary instruments or some personal carrying articles.

[0033] The lifting rod 5 is preferably a lifting air rod. By adjusting the height of the lifting rod 5, the height of the seat body 1 can be adjusted, so as to meet the use of users of different heights, and the user is more comfortable when sitting. The bottom of the seat body 1 is fixed with a support disc 3, and the bottom of the support disc 3 is provided with a mounting sleeve 4 for mounting the lifting rod 5, and the telescopic end of the lifting rod 5 is fixed in the mounting sleeve 4. A flexible seat cushion 2 is arranged on the seat body 1, and the flexible seat cushion 2 is connected with the seat body 1 by magic tape.

[0034] Each moving wheel pair 8 comprises two wheels 81, an axle 82 and two first nuts 83. Each wheel 81 is provided with an axis hole matched with the axle 82, and the two wheels 81 are rotatably installed at both ends of the axle 82. The wheels 81 and the axle 82 are matched by clearance. The wheels 81 are preferably hollow plastic wheels, and the wheels 81 are in cylindrical shape. Anti-skid lines can be arranged on the outside of the wheels 81, so that the wheels 81 can also move on the wet soil surface. The both ends of the axle 82 are provided with external threads matched with the first nuts 83, and the lower mounting seat 92 is provided with a fixed through hole for mounting the axle 82. The wheels 81 are rotatably fixed at the ends of the axle 82, and the first nuts 83 are used for limiting the wheels 81. A stepped portion can also be arranged on the axle 82 for limiting the wheels 81. The wheels 81 are made of hollow plastic, have large supporting stress area and light weight, are not easy to sink into the soil surface, and have good compacting effect on the soil surface.

[0035] Working process and principle:

[0036] The flexible steering mechanism 9 is similar to the moving wheel structure of a skateboard. When turning, the downward pressure on the turning side is increased, the bolt 93 is in clearance fit with the lower mounting seat 92, the upper rubber ball 97 is extruded by the upper support bowl 95, the lower rubber ball 98 is extruded by the lower support bowl 96, the upper rubber ball 97 and the lower rubber ball 98 are deformed, the upper bolt 93 is deflected relative to the lower mounting seat 92, when the user sitting on the seat body 1 turns to the side that needs to turn, the downward pressure on the turning side is increased, then the angle of the bolt 93 relative to the lower mounting seat 92 changes, the upper rubber ball 97 and the lower rubber ball 98 are extruded by the upper support bowl 95 and the lower support bowl 96 respectively, the bolt 93 moves to the turning side relative to the lower mounting seat 92, but due to the fulcrum effect of the support column 99 and the upper mounting seat 91, the lower mounting seat 92 rotates to the turning side relative to the upper mounting seat 91, in this process, the upper rubber ball 97 and the lower rubber ball 98 are partially deformed on the turning circumference, so as to realize the rotation of the lower mounting seat 92 driving the wheel shaft 82. The user can increase the downward pressure on the turning side, the moving wheel pair 8 is turned to the turning side by the flexible steering mechanism 9, so as to realize the turning of the flexible steering mechanism 9, the user balances the downward pressure on the left and right sides, the moving wheel pair 8 located on the front side returns to the straight line moving position under the elastic return effect of the upper rubber ball 87 and the lower rubber ball 98. The turning process does not require the user to get up, the turning efficiency is more efficient, the user avoids getting up frequently, and the labor intensity of the user is reduced.
