[0030] During use, the staff connects it to the agricultural machine through the connecting head 9, and at the same time, with the help of the fixed shaft 3 movably connected to the fixed ring 2 through the bearing, the connecting frame 15 on the packaging tube 4 can drive the supporting shaft 13 to rotate around the fixed shaft 3. In order to enhance the connection stability between the fixed shaft 3 and the fixed ring 2 and reduce wear, the staff can transport the lubricating oil to the inside of the packaging tube 4 through the top opening of the packaging tube 4, and guide the flow direction of the lubricating oil through the spiral guidance of the spiral sheet 5. Among them, since a plurality of material holes 7 corresponding to the spiral sheets 5 are provided on the outside of the fixed ring 2, the lubricating oil falling in a spiral shape can fall to the outside of the bearing between the fixed shaft 3 and the fixed ring 2 in all directions through the plurality of material holes 7, thereby reducing wear and ensuring the connection stability between the fixed shaft 3 and the fixed ring 2, and the excess lubricating oil is transported to the material hole 7 through the spiral sheet 5 for discharge, so as to avoid the accumulation of lubricating oil and affect the subsequent lubrication use.

[0031] At the same time, in order to prevent dust and other impurities from entering the packaging tube 4 and contaminating the lubricating oil, it is necessary to block the dust and other impurities, such as Figure 3 and Figure 4 As shown, two mirror-distributed filter rings 10 are provided inside the top of the packaging tube 4, and a ring groove 11 is opened on one side of the top of the packaging tube 4 corresponding to the filter ring 10, and the filter ring 10 is arranged inside the ring groove 11, and a fastening bolt 12 is provided on the top of the end away from the two filter rings 10, and the bottom end of the fastening bolt 12 passes through the filter ring 10 and extends into the packaging tube 4, and the fastening bolt 12 is threadedly connected to the packaging tube 4, and the filter ring 10 is installed in the ring groove 11 in the packaging tube 4 by the fastening bolt 12, so that the top of the packaging tube 4 can be packaged by the filter ring 10, so as to achieve the effect of blocking impurities such as dust, and prevent dust and other impurities from entering the interior of the packaging tube 4 to contaminate the lubricating oil, and the detachable connection of the fastening bolt 12 can conveniently remove the filter ring 10 for inspection and maintenance.

[0032] In order to reduce the resistance of the trailer board 1 when turning, it is necessary to adjust the steering of the front wheel 14, such as Figure 2 and Figure 3 As shown, the connecting piece includes a connecting bracket 8 arranged at the bottom of the front end of the trailer board 1, and a connecting head 9 is installed at the front end of the connecting bracket 8 by bolts. A support shaft 13 is provided at the bottom of the packaging tube 4, and front wheels 14 are installed at both ends of the support shaft 13. Two connecting frames 15 are provided between the two front wheels 14. The bottom end of the connecting frame 15 is sleeved on the outside of the support shaft 13, and the end of the connecting frame 15 away from the support shaft 13 is fixed to one side of the packaging tube 4. The rear end of the connecting bracket 8 is sleeved on the outside of the support shaft 13. The staff can connect the connecting bracket 8 to the packaging tube 4. The connector 9 on the bracket 8 is connected to the agricultural machine, and the trailer board 1 is driven by the agricultural machine for mobile transportation. At the same time, through the connection between the connecting bracket 8 and the support shaft 13, the connecting bracket 8 can drive the support shaft 13 to move synchronously. Because the support shaft 13 is connected to the packaging tube 4 with the help of the connecting frame 15, the support shaft 13 drives the front wheel 14 to rotate around the fixed shaft 3. Therefore, when the connecting bracket 8 drives the support shaft 13 to steer and adjust, the front wheel 14 can also steer and adjust together, thereby improving the steering adjustment convenience of the front wheel 14.
