Specific implementation method:

[0035] The present invention is further described below with reference to specific embodiments. Figure 1 —4:

[0036] A bean sprout turning and conveying device comprises a frame 1 and a turning frame 2 rotatably connected to the frame 1, a seedling box 3 is arranged on the turning frame 2, a clamping device 4 is slidably arranged on the turning frame 2, when the seedling box 3 needs to be turned over, the clamping device 4 moves to one side of the seedling box 3 and clamps the seedling box 3 to prevent the seedling box 3 from moving relative to the turning frame 2; when the seedling box 3 needs to be put in or taken out, the clamping device 4 is reset to the opposite direction.

[0037] In this embodiment, the left-right direction is the horizontal direction, the front-back direction is the longitudinal direction, and the up-down direction is the vertical direction.

[0038] The working principle of the utility model is as follows: after the seedling box 3 is placed on the turning frame 2, the clamping device 4 moves to one side of the seedling box 3 and clamps the seedling box 3 to prevent the seedling box 3 from moving relative to the turning frame 2, and the turning frame 2 rotates and turns around the rotating shaft 10 between it and the frame 1, driving the seedling box 3 to rotate and turn around the rotating shaft 10, and the bean sprouts in the seedling box 3 fall on the platform in front of the frame 1; after the bean sprouts in the seedling box 3 fall completely, the turning frame 2 rotates in the opposite direction around the rotating shaft 10, driving the seedling box 3 to rotate in the opposite direction around the rotating shaft 10, and after the turning frame 2 is reset, the clamping device 4 is reset, the seedling box 3 is taken out, and another seedling box 3 is put in.

[0039] like Figure 1-3 As shown, the utility model has a clamping device slidably arranged on the flip frame 2. When the seedling box 3 needs to be flipped, the clamping device 4 clamps the seedling box 3, and the limiting effect is good, which effectively prevents the seedling box 3 from flipping forward and downward and falling. When the seedling box 3 is taken and placed, the clamping device leaves the seedling box 3, effectively avoiding the seedling box 3 to avoid affecting the taking and placing of the seedling box 3.

[0040] In order to achieve a better clamping effect and further prevent the seedling box 3 from moving relative to the turning frame 2 during turning, clamping devices 4 are provided on both sides of the turning frame 2.

[0041] The structure of the seedling box 3 and the clamping device 4: the seedling box 3 includes a box body 31 and a base arranged below the box body 31, the base includes a frame composed of frame strips 32 and a support column 33 arranged below the frame, the clamping device 4 includes an upper clamping plate 41, a lower clamping plate 42, and a connecting plate 43 connecting the upper clamping plate 41 and the lower clamping plate 42. When the seedling box 3 needs to be turned over, the corresponding frame strip 32 is arranged between the upper clamping plate 41 and the lower clamping plate 42, which has a good limiting effect and a simple structure, and is easy to process and install.

[0042] In order to facilitate the sliding of the clamping device 4, Figure 1 , 3 As shown, the flip frame 2 is equipped with a cylinder 5, a guide bar 9, and an elastic member for resetting the clamping device 4. The clamping device 4 is provided with a mounting sleeve 7 that is slidably mounted on the piston rod 6 of the cylinder 5. The mounting sleeve 7 is slidably mounted in the guide bar 9. When the seedling box 3 needs to be flipped, the piston rod 6 is pushed out to push the clamping device 4 to move to one side of the seedling box 3, and the elastic member undergoes elastic deformation; when the seedling box 3 needs to be put in or taken out, the piston rod 6 retracts, and the clamping device 4 moves in the opposite direction under the elastic force of the elastic member, and the elastic member is reset. The guide bar 9 can be set to guide the sliding of the mounting sleeve 7 well, that is, to guide the sliding of the clamping device 4, so that the clamping device 4 can always clamp the seedling box 3 well. The mounting sleeve 7 is not fixed on the piston rod 6, but is slidably mounted on the piston rod 6, so that the expansion and contraction of the piston rod 6 can have a certain deviation from the sliding of the mounting sleeve 7, and the installation accuracy of the cylinder 5 and the processing accuracy of the mounting sleeve 7 are low.

[0043] Furthermore, a mounting plate 8 is provided on the turning frame 2 , and the cylinder 5 and the guide bar 9 are both fixedly mounted on the mounting plate 8 .

[0044] In this embodiment, the elastic member is a tension spring, one end of which is connected to the clamping device 4 or the mounting sleeve 7 , and the other end of which is connected to the mounting plate 8 .

[0045] The mounting structure of the mounting plate 8: the mounting plate 8 is fixed on the flip frame 2 by welding, and the connection is firm and reliable.

[0046] In order to enable the clamping device 4 to clamp the seedling box 3 in time when the turning frame 2 is turned over, and effectively prevent the seedling box 3 from falling, a controller is also included. A micro switch 1 is provided on the frame 1 for detecting whether the turning frame 2 is turned upward, and the cylinder 5 and the micro switch 1 are electrically connected to the controller respectively.

[0047] Furthermore, the micro switch 1 is arranged below the flip frame 2 .

[0048] When the flipping frame 2 leaves the triggering end of the microswitch 1, the microswitch 1 transmits a signal to the controller, the controller drives the cylinder 5 to extend the piston rod 6, and the clamping device 4 moves to the side of the seedling box 3 to clamp the seedling box 3; when the flipping frame 2 is reset after completing the flipping and contacts the triggering end of the microswitch 1, the microswitch 1 transmits a signal to the controller, the controller drives the cylinder 5 to retract the piston rod 6, the clamping device 4 moves to the side away from the seedling box 3, and the clamping device 4 leaves the seedling box.

[0049] The structure of the flip frame 2: The flip frame 2 includes a bottom plate 21 for placing a seedling box 3, and side plates 22 are respectively provided on the left and right sides of the bottom plate 21. A horizontal bar 23 connecting the two side plates 22 is provided on the rear side of the bottom plate 21. The side plates 22 are rotatably connected to the frame 1 through a rotating shaft 10, and the rotating shaft 10 is arranged at the rear end of the side plates 22.

[0050] In order to prevent the seedling box 3 from falling from the gap between the horizontal bars 23 and to provide better strength for the overturning frame 2, more than two horizontal bars 23 are provided, and a plurality of vertical bars 24 are connected between two adjacent horizontal bars 23. In the present embodiment, two horizontal bars 23 are provided.

[0051] In order to reduce the weight of the side panels 22 as much as possible while ensuring the strength of the side panels 22, the side panels 22 include an outer frame and support bars arranged in the outer frame. The outer frame is composed of a plurality of frame bars adjacent end to end.

[0052] Rotation structure of the turning frame 2: the rotating shaft 10 is rotationally connected to the frame 1 through a bearing, and the rotating shaft 10 is driven to rotate by a motor arranged on the frame 1. Driven by the motor, the rotating shaft 10 can rotate slowly and steadily, and the rotation angle can be accurately controlled.

[0053] In order to decelerate the motor, the output shaft of the motor is connected to the input shaft of the reducer, a small gear is arranged on the output shaft of the reducer, and a large gear meshing with the small gear is arranged on the rotating shaft 10 .

[0054] In order to guide the bean sprouts in the seedling box 3 and prevent them from scattering on the ground, a fence is provided above the turning frame 2, and the fence includes a rear panel 11 arranged on a horizontal bar 23, and side panels 12 are respectively provided on both sides of the rear panel 11, and the side panels 12 are connected to the corresponding side panels 22.

[0055] Preferably, the rear panel 11 and the side panels 12 are an integrated structure.

[0056] In order to prevent the over-turning of the turning frame 2, the frame 1 is provided with a stop bar 13 for limiting the rotation position of the turning frame 2, and the upper end of the turning frame 2 is provided with a buffer elastic block for contacting and buffering with the stop bar 13. The frame 1 is provided with a micro switch 2 for detecting whether the turning frame 2 is rotated into place, and the micro switch 2 and the motor are electrically connected to the controller respectively. The setting of the buffer elastic block converts the rigid contact between the turning frame 2 and the frame 1 into a flexible contact for buffering. The setting of the micro switch 2 prevents the motor from still working after the turning frame 2 moves into place, thereby damaging the motor.

[0057] When the flip frame 2 contacts the trigger end of the micro switch 2, the controller controls the motor to stop rotating.

[0058] Furthermore, the blocking bar 13 is located below the rotating shaft 10 , and the second micro switch is arranged below the flip frame 2 .

[0059] Furthermore, the material of the buffer elastic block is rubber or elastic plastic.

[0060] The above embodiment is only one of the preferred embodiments of the present utility model, and is not intended to limit the scope of implementation of the present utility model. Therefore, any equivalent changes made based on the shape, structure, and principle of the present utility model should be included in the protection scope of the present utility model.
