[0029] The rotating track 11 includes a fixed frame 111, a turntable assembly 112, a rotating frame 113, and a rotating track pushing wheel assembly 114.

[0030] The fixed frame 111 is a metal frame structure, fixed on the ground, and a turntable assembly 112 is provided on the top.

[0031] The turntable assembly 112 includes a disc-shaped top surface and a bottom surface. The top surface is fixedly connected to the rotating frame 113, and the bottom surface is fixedly connected to the fixed frame 111. A slewing bearing is provided between the top surface and the bottom surface, so that the top surface and the bottom surface can rotate around their axis. Its specific structure is common knowledge in the field. The applicant selects commercially available existing products when implementing this assembly.

[0032] The rotating frame 113 includes a support frame body 1131, three fixed rotating wheels 1132, and a driving wheel assembly 1133. The axes of rotation of the wheels of the three fixed rotating wheels 1132 and the driving wheel assembly 1133 pass through the central axis of the turntable assembly 112. Driven by the driving wheel assembly 1133, the rotating frame 113 can rotate relative to the fixed frame 111.

[0033] As shown in the Figure 5 accompanying 7 figures, the driving wheel assembly 1133 includes a driving motor q4, a driving wheel support q1, a driving wheel q2, and a driving wheel frame q3. The driving wheel frame is fixed on the rotating frame 113, and a flange is provided at the bottom.

The driving motor is fixed on the driving wheel support and drives the driving wheel to rotate. The angle of the driving wheel can be adjusted through the driving wheel frame and the flange of the driving wheel support. Correspondingly, the fixed rotating wheel 1132 also includes a fixed wheel support l3, a fixed wheel l2, and a fixed wheel frame l1. The fixed wheel frame is fixed on the rotating frame 113, and a flange is provided at the bottom.

[0035] For the Figure 2 application scenario shown in the accompanying figures, the rotating frame 113 only rotates around the axis of the turntable assembly 112 within a range of 90 degrees. As shown in the Figure 7 accompanying figures, stoppers D1 can be provided at the extreme positions of the movement of the fixed rotating wheels 1132 and / or the driving wheel assembly 1133.

[0036] To achieve precise control of the rotation, in one embodiment of the present application, a position-in-place monitoring device assembly D2 is provided on the rotating frame 113. As shown in the Figure 5 accompanying 7 figures, the position-in-place monitoring device assembly D2 is provided below the rotating frame 113 and includes a monitoring support D21, two inductive sensors D22 provided on the monitoring support D21, and a metal block D23 provided at the position on the ground corresponding to the inductive sensors D22 when the rotating frame 113 is at the extreme position. After the inductive sensors D22 reach the area of the metal block D23, the change in inductance can be detected to achieve position-in-place monitoring.

[0037] For the convenience of subsequent maintenance of the equipment, two inductive sensors D22 are provided in this application to detect the positions of two limit positions respectively, which is convenient for subsequent equipment debugging and maintenance. Specifically, the two inductive sensors D22 are arranged along the length direction parallel to the rotating frame 113.

[0038] Furthermore, a rotating track can also be provided on the ground. There are two rotating tracks. One track is shared by two fixed rotating wheels 1132 on one side of the turntable assembly 112, and the other track is shared by one fixed rotating wheel 1132 and the drive wheel assembly 1133 on the other side. Positioning and limiting devices are provided on the track.

[0039] The rotating track driving wheel assembly 114 includes a plurality of rolling wheels t1, a driving motor t2, and a driving wheel t3. The driving motor t2 drives the driving wheel t3 to rotate, and the seedbed is pushed to move on the rolling wheels t1.

[0040] As shown in the appendix Figure 5 As shown, the rolling wheels t1, the driving motor t2, and the driving wheel t3 can be directly arranged on both sides of the rotating frame 113 (only the structures of the rolling wheels t1, the driving motor t2, and the driving wheel t3 on one side are drawn in the appendix Figure 5 ),

[0041] It can be arranged on both sides of the rolling wheel t1 bracket t4 as shown in the appendix Figure 6 As shown, and then the rolling wheel t1 bracket is fixedly arranged on the rotating frame 113.

[0042] As shown in the appendix Figure 5 , 6 As shown, the principle of the rotating track driving wheel assembly 114 is the same as that of the driving wheel assembly A01 on the track unit A0 in the appendix Figure 4 , and the layout structures of the rolling wheels t1, the driving motor t2, and the driving wheel t3 are also basically the same.

[0043] During use, the seedbed is pushed out from the vertical transfer column to the horizontal (forward) transfer track through the tractor, rotated 90° to the vertical transfer track by the rotating track 11. After the outbound and inbound operations are performed in the operation area, it is transported to the rotating track 11 through the vertical transfer track. The rotating track 11 rotates the seedbed 90° to the horizontal (reverse) transfer track, and then is transported to the vertical transfer column through the tractor to reach the designated area.

[0044] Taking the applicant's practice as an example, after adopting the technical solution of this application, compared with the appendix Figure 1In the existing solution shown, the operating area for seedling emergence and seedling input has increased. The operating area of the original solution was 145 square meters, while the operating area of the modified solution is 570 square meters. In the original solution, manual operations were carried out on 1 seedbed in the operating area. In the modified solution, manual operations can be carried out on 8 seedbeds simultaneously, and it meets the requirements of simultaneous seedling emergence and seedling input. The turnover time of the seedbed is reduced, and the turnover speed of the seedbed is increased. To complete the operations of taking out and storing the seedbed at the last row at the farthest end of the greenhouse in the original solution, it took 47 minutes. The modified solution can compress the time to 35 minutes, saving 12 minutes of seedbed turnover time. (The above time is only for the realization of the system turnover operation and does not consider the time of manual operations in the operating area.)

[0045] It should be noted that unless otherwise clearly specified and limited, terms such as "installation", "connection", "linkage", "fixation", "setting" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
