[0012] Preferably, the method for using the rice seedling raising rack for factory-based rice cultivation comprises the following steps:

[0013] S1: When raising rice seedlings, the seedlings are placed on several trays. When the seedlings are exposed to sunlight during the production process, the driving motor drives the driving disc to rotate. The driving disc rotates through the transmission belt between the driving disc and the two rotating discs, which drives the two rotating discs to rotate synchronously. When the rotating disc rotates, the rotating disc drives the rotating clamping rod to rotate. The rotation of the rotating clamping rod drives the rotating clamping sleeve in the carrying box to rotate. The rotation of the rotating clamping sleeve enables the rotating bevel gear to drive the adjusting bevel gear to rotate. The rotation of the adjusting bevel gear drives the adjusting rod to rotate. The adjusting frame on the adjusting rod enables the clamping tray to deflect.

[0014] S2: When several trays are deflected under the drive of the adjustment frame, the rotating clamping rod drives the rotating gear to rotate under the rotation of the rotating clamping rod, and the rotating gear drives the rotating gear to rotate, and the rotating gear causes the spiral rod to rotate, and the rotation of the spiral rod drives the carrying box close to the top of the carrying bracket to move toward the bottom of the carrying bracket. At this time, when the carrying box close to the carrying bracket moves downward, the carrying box will cause several carrying boxes to move downward synchronously through the folding connecting rod, so that when the angle of the trays set on the carrying box is deflected, the distance between the trays can be expanded, so that the sunlight can be more fully exposed to the seedlings;

[0015] S3: When the tray is installed with the carrying box, the connecting frame on the tray is correspondingly connected with the adjusting frame, and the connecting chuck on the tray will slide in the card cavity in the outer shell. When the annular card strip on the connecting chuck moves to the surface of the outer shell, the pressure spring drives the resistance rod to slide on the outer shell, and the card groove on the resistance rod causes the two locking blocks to deflect on the outer shell. The annular card strip is at the inner bottom of the card cavity, and the two locking blocks deflect and move toward the card cavity. The locking blocks will be pressed against the end surface of the annular card strip to limit the annular card strip.

[0016] S4: As the seedlings continue to grow, when the operator needs to remove the tray from the carrying box, the rotating clamping rod is rotated to drive the rotating clamping sleeve to rotate, and the rotating clamping sleeve is rotated to drive the convex plate to rotate. The swing frame is driven by the torsion spring to make the swing frame close to the surface of the convex plate. When the convex plate rotates, the concave end of the convex plate contacts the swing frame, and the end of the swing frame provided with the inclined surface will deflect toward the direction of the interference wheel. When the interference wheel contacts the inclined surface of the swing frame, the unlocking frame will move downward under the pressure of the inclined surface. At this time, the wedge-shaped end on the unlocking frame contacts the wedge-shaped groove on the interference rod, which will make the interference rod slide in the outer shell. When the interference rod slides, the two locking blocks are deflected through the clamping groove, thereby releasing the pressing limit of the annular clamping strip on the connecting clamp, so that the tray can be disassembled.

[0017] S5: When cultivating the seedlings, a fixed amount of pesticide needs to be sprayed on the seedlings. When the rotating clamping rod rotates, the rotating clamping rod will drive the second bevel gear to rotate the first bevel gear. The rotation of the first bevel gear drives the rotating rod to rotate, thereby rotating the eccentric frame on the rotating rod. When the eccentric frame rotates, the arc-shaped limit teeth on both sides of the eccentric frame contact the adjusting rack and the limit rack respectively. Because the arc-shaped limit teeth on one side of the eccentric frame are limited by the adjusting rack, the limit rack is movably set on the fixed frame, and then when the eccentric frame rotates, the arc-shaped limit teeth on the other side can drive the limit rack movably set on the fixed frame to slide on the fixed frame. At this time, the sieve rod at the bottom of the limit rack will squeeze the pesticide stored in the water tank, so that the pesticide can be discharged into a plurality of water spray pipes;

[0018] S6: When the seedlings grow gradually, the driving motor needs to drive the mobile adjustment device to increase the angle and spacing between the trays so that the seedlings can fully receive sunlight, and at the same time, the amount of pesticide sprayed on the seedlings needs to be increased. When the rotating gear rotates to drive the moving tooth plate to move, the extrusion spring drives the clamping wheel on the adjustment rack to fit tightly against the inclined surface of the extrusion block. The moving tooth plate will drive the extrusion block to contact the clamping wheel on the adjustment rack, so that the adjustment rack slides on the fixed frame. The change in the position of the adjustment rack will change the deflection amplitude of the eccentric frame, and then the eccentric frame drives the limit rack to move back and forth on the fixed frame, which can increase the movement amplitude of the screen rod, thereby increasing the discharge amount from the water tank to the water pipe.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the present invention, the adjustment frame on the adjustment rod enables the trays that are connected to deflect, so that a plurality of trays that are arranged vertically at equal intervals are inclined, so that the seedlings on the trays can fully contact the sunlight and grow evenly.

[0021] In the present invention, the carrying box can move down synchronously with several carrying boxes through a folding connecting rod, so that the distance between the trays arranged on the carrying box can be expanded when the angle is deflected, so that the sunlight can be in contact with the seedlings more fully. When several trays of seedlings are close to each other, the distance between the trays is shortened, which can achieve the effect of keeping the seedlings warm.

[0022] In the present invention, when the annular clamping strip on the connecting chuck moves to the surface of the outer shell, the pressure spring drives the resistance rod to slide on the outer shell, and the groove on the resistance rod causes the two locking blocks to deflect on the outer shell. The annular clamping strip is at the inner bottom of the clamping cavity, and the two locking blocks deflect and move toward the direction of the clamping cavity. The locking blocks will be squeezed with the end faces of the annular clamping strip to limit the annular clamping strip, so that the pallet can be stably restricted on the carrying box, and then the pallet can be stably adjusted when the movable adjustment device adjusts the position angle of the pallet.

[0023] In the present invention, when the tray needs to be disassembled, the tray can first be tilted by rotating the rotating sleeve, and there is a certain distance between each tray, so that the seedlings between each tray will not be affected when the tray is disassembled, and the rotation of the rotating clamping rod can synchronously drive the cams on several carrying boxes to rotate synchronously, so that several trays can be unlocked synchronously, thereby eliminating the need for the operator to unlock each tray one by one, which is convenient for the operator to use.

[0024] In the present invention, when the eccentric frame drives the limit rack to reciprocate on the fixed frame, the movement range of the screen rod can be enlarged, thereby increasing the discharge amount from the water tank to the water pipe, and further allowing the spraying amount of pesticide to correspond to the growth of the seedlings.

[0042] The carrying boxes 31 on the two movable adjustment devices 3 are respectively arranged on the two rotating clamping rods 22 and the spiral rod 26, and a folding connecting rod 32 is hingedly arranged between the longitudinally arranged carrying boxes 31, and a spiral sleeve 33 spirally matched with the spiral rod 26 is arranged on the carrying box 31 close to the top of the carrying bracket 1;

[0043] A rotating sleeve 34 is rotatably provided in each carrying box 31, and the rotating sleeve 34 is engaged with the rotating engaging rod 22. An adjusting rod 35 is also rotatably provided in the carrying box 31, and an adjusting bevel gear 36 is fixedly connected to the adjusting rod 35.

[0044] When raising rice seedlings, the seedlings are placed on a plurality of trays 4. When sunlight is irradiated during the seedling production process, the driving motor 21 drives the driving disc 24 to rotate. The driving disc 24 rotates through the transmission belt 25 between the driving disc 24 and the two rotating discs 23, which drives the two rotating discs 23 to rotate synchronously. When the rotating disc 23 rotates, the rotating disc 23 drives the rotating clamping rod 22 to rotate.

[0048] When the tray 4 is installed between the carrying box 31, the connecting frame 42 on the tray 4 is correspondingly connected with the adjusting frame 38, and the connecting chuck 43 on the tray 4 will slide in the card cavity 52 in the outer shell 51. When the annular clamping strip 44 on the connecting chuck 43 moves to the surface of the outer shell 51, the pressure spring 55 drives the contact rod 53 to slide on the outer shell 51, and the card groove 54 on the contact rod 53 causes the two locking blocks 56 to deflect on the outer shell 51. The annular clamping strip 44 is at the inner bottom of the card cavity 52, and the two locking blocks 56 deflect and move toward the direction of the card cavity 52. ​​The locking blocks 56 will be squeezed with the end face of the annular clamping strip 44 to limit the annular clamping strip 44, so that the tray 4 can be stably restricted on the carrying box 31, and then the tray 4 can be stably adjusted when the movable adjustment device 3 adjusts the position angle of the tray 4.

[0049] In this embodiment, Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig.12 and Fig.13 As shown, the locking device 5 also includes an unlocking frame 57 slidably arranged on the outer shell 51, and a resistance wheel 58 is rotatably arranged on the top of the unlocking frame 57. The unlocking frame 57 is wedge-shaped, and a wedge-shaped groove 59 is also provided on the resistance rod 53. The wedge-shaped end of the unlocking frame 57 contacts the wedge-shaped groove on the resistance rod 53. A connecting spring 510 is also sleeved on the unlocking frame 57, and the two ends of the connecting spring 510 are respectively connected to the outer shell 51 and the unlocking frame 57.

[0050] As the seedlings continue to grow, when the operator needs to remove the tray 4 from the carrying box 31, the rotating clamping rod 22 is rotated to drive the rotating clamping sleeve 34 to rotate, and the rotating clamping sleeve 34 rotates to drive the cam 511 to rotate. The swing frame 512 is driven by the torsion spring 513 to make the swing frame 512 close to the surface of the cam 511. When the cam 511 rotates, the recessed end of the cam 511 contacts the swing frame 512, and the end of the swing frame 512 with the inclined surface will deflect toward the direction of the interference wheel 58. When the interference wheel 58 contacts the inclined surface of the swing frame 512, the unlocking frame 57 will be squeezed by the inclined surface to move downward. At this time, the wedge-shaped end on the unlocking frame 57 contacts the wedge-shaped groove on the interference rod 53, which will cause the interference rod 53 to The outer shell 51 slides, and when the resistance rod 53 slides, the two locking blocks 56 are deflected through the card slot 54, thereby releasing the press limit on the annular card strip 44 on the connecting card plate 43, so that the tray 4 can be disassembled. Through this arrangement, when the tray 4 needs to be disassembled, the rotation of the rotating card sleeve 34 can first make the tray 4 in an inclined state, and there is a certain distance between each tray 4, so that the seedlings between each tray 4 will not be affected when the tray 4 is disassembled, and the rotation of the rotating card connecting rod 22 can synchronously drive the convex plates 511 on the several carrying boxes 31 to rotate synchronously, so that several trays 4 can be unlocked synchronously, so that the operator does not need to unlock each tray 4 one by one, which is convenient for the operator to use.

[0052] When cultivating the seedlings, it is necessary to spray a certain amount of pesticide on the seedlings. When the rotating clamping rod 22 rotates, the rotating clamping rod 22 will drive the second bevel gear 66 to rotate the first bevel gear 65. The rotation of the first bevel gear 65 drives the rotating rod 62 to rotate, thereby rotating the eccentric frame 64 on the rotating rod 62. When the eccentric frame 64 rotates, the arc-shaped limiting teeth 69 on both sides of the eccentric frame 64 contact the adjusting rack 67 and the limiting rack 68 respectively. Because the arc-shaped limiting teeth 69 on one side of the eccentric frame 64 are adjusted by the adjusting rack 67, the limiting teeth 68 on one side of the eccentric frame 64 are adjusted by the adjusting rack 67. 7 Limiting, the limiting rack 68 is movably arranged on the fixing frame 61, and when the eccentric frame 64 rotates, the arc-shaped limiting teeth 69 on the other side can drive the limiting rack 68 movably arranged on the fixing frame 61 to slide on the fixing frame 61, and at this time, the sieve rod 610 at the bottom of the limiting rack 68 will squeeze the pesticide stored in the water tank 11, so that the pesticide can be discharged into the plurality of spray pipes 12, so that the spray pipes 12 can spray the pesticide onto the seedlings on the tray 4, so that the seedlings can contact with the pesticide and grow smoothly;

[0053] When the seedlings grow gradually, the driving motor 21 needs to drive the mobile adjustment device 3 to increase the angle and spacing between the trays 4 so that the seedlings can fully receive sunlight, and at the same time, the amount of pesticide sprayed on the seedlings needs to be increased. When the rotating gear 27 rotates to drive the moving tooth plate 611 to move, the squeezing spring 614 drives the card wheel 613 on the adjustment rack 67 to fit closely with the inclined surface of the squeezing block 612, and the moving tooth plate 611 drives the squeezing block 612 to fit closely with the adjusting rack 67. When the clamping wheel 613 contacts, the adjusting rack 67 slides on the fixing frame 61. When the adjusting rack 67 slides on the fixing frame 61, the change in the position of the adjusting rack 67 will change the deflection amplitude of the eccentric frame 64, and then the eccentric frame 64 drives the limiting rack 68 to move back and forth on the fixing frame 61, which can increase the movement amplitude of the screen rod 610, thereby increasing the discharge amount of the water tank 11 into the water pipe, and then the spraying amount of pesticide can correspond to the growth of the seedlings.

[0054] The use method and advantages of the present invention: The use method of the rice seedling raising frame for factory cultivation has the following working process:

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 As shown:

[0056] S1: When raising rice seedlings, the seedlings are placed on a plurality of trays 4. When sunlight is irradiated during the seedling production process, the driving motor 21 drives the driving disc 24 to rotate. The driving disc 24 rotates through the transmission belt 25 between the driving disc 24 and the two rotating discs 23, which drives the two rotating discs 23 to rotate synchronously. When the rotating disc 23 rotates, the rotating disc 23 drives the rotating clamping rod 22 to rotate. The rotating clamping rod 22 rotates to drive the rotating clamping sleeve 34 in the carrying box 31 to rotate. The rotating clamping sleeve 34 rotates to enable the rotating bevel gear 37 to drive the adjusting bevel gear 36 to rotate. The adjusting bevel gear 36 rotates to drive the adjusting rod 35 to rotate. The adjusting frame 38 on the adjusting rod 35 enables the clamping tray 4 to deflect.

[0057] S2: When the plurality of trays 4 are deflected under the drive of the adjustment frame 38, the rotating clamping rod 22 drives the rotating gear 28 to rotate under the rotation of the rotating clamping rod 22, and the rotating gear 28 drives the rotating gear 27 to rotate, and the rotating gear 27 causes the spiral rod 26 to rotate, and the rotation of the spiral rod 26 drives the carrying box 31 close to the top of the carrying bracket 1 to move toward the bottom of the carrying bracket 1. At this time, when the carrying box 31 close to the carrying bracket 1 moves downward, the carrying box 31 will make the plurality of carrying boxes 31 move downward synchronously through the folding connecting rod 32, so that the angle of the trays 4 set on the carrying box 31 can be deflected to expand the distance between the trays 4, so that the sunlight can be more fully in contact with the seedlings;

[0058] S3: When the tray 4 is installed between the carrying box 31, the connecting frame 42 on the tray 4 is correspondingly connected with the adjusting frame 38, and the connecting chuck 43 on the tray 4 will slide in the card cavity 52 in the outer shell 51. When the annular clamping strip 44 on the connecting chuck 43 moves to the surface of the outer shell 51, the pressure spring 55 drives the resistance rod 53 to slide on the outer shell 51, and the card groove 54 on the resistance rod 53 makes the two locking blocks 56 deflect on the outer shell 51. The annular clamping strip 44 is at the inner bottom of the card cavity 52, and the two locking blocks 56 deflect and move toward the card cavity 52. ​​The locking blocks 56 will be squeezed with the end surface of the annular clamping strip 44 to limit the annular clamping strip 44.

[0059] S4: As the seedlings continue to grow, when the operator needs to remove the tray 4 from the carrying box 31, the rotating clamping rod 22 is rotated to drive the rotating clamping sleeve 34 to rotate, and the rotating clamping sleeve 34 rotates to drive the convex plate 511 to rotate. The swing frame 512 is driven by the torsion spring 513 to make the swing frame 512 and the surface of the convex plate 511 close to each other. When the convex plate 511 rotates, the concave end of the convex plate 511 contacts the swing frame 512, and the end of the swing frame 512 with the inclined surface is The locking member 56 is deflected toward the direction of the contact wheel 58. When the contact wheel 58 contacts the inclined surface of the swing frame 512, the unlocking frame 57 is pressed downward by the inclined surface. At this time, the wedge-shaped end of the unlocking frame 57 contacts the wedge-shaped groove on the contact rod 53, which causes the contact rod 53 to slide in the outer shell 51. When the contact rod 53 slides, the two locking blocks 56 are deflected through the card slot 54, thereby releasing the pressing limit of the annular card strip 44 on the connecting chuck 43, so that the tray 4 can be disassembled.

[0060] S5: When cultivating the seedlings, a certain amount of pesticide needs to be sprayed on the seedlings. When the rotating clamping rod 22 rotates, the rotating clamping rod 22 will drive the second bevel gear 66 to rotate the first bevel gear 65. The rotation of the first bevel gear 65 drives the rotating rod 62 to rotate, thereby rotating the eccentric frame 64 on the rotating rod 62. When the eccentric frame 64 rotates, the arc-shaped limiting teeth 69 on both sides of the eccentric frame 64 contact the adjusting rack 67 and the limiting rack 68 respectively. Because the arc-shaped limiting teeth 69 on one side of the eccentric frame 64 are limited by the adjusting rack 67, the limiting rack 68 is movably arranged on the fixed frame 61, and then when the eccentric frame 64 rotates, the arc-shaped limiting teeth 69 on the other side can drive the limiting rack 68 movably arranged on the fixed frame 61 to slide on the fixed frame 61. At this time, the sieve rod 610 at the bottom of the limiting rack 68 will squeeze the pesticide stored in the water tank 11, so that the pesticide can be discharged into a plurality of water spray pipes 12;

[0061] S6: When the seedlings grow gradually, the driving motor 21 needs to drive the moving adjustment device 3 to increase the angle and spacing between the trays 4, so that the seedlings can fully receive sunlight, and at the same time, the amount of pesticide sprayed on the seedlings needs to be increased. When the rotating gear 27 rotates and drives the moving tooth plate 611 to move, the extrusion spring 614 drives the card wheel 613 on the adjustment rack 67 to be in close contact with the inclined surface of the extrusion block 612, and the moving tooth plate 611 will drive the extrusion block 612 to contact the card wheel 613 on the adjustment rack 67, so that the adjustment rack 67 slides on the fixed frame 61. When the adjustment rack 67 slides on the fixed frame 61, the change in the position of the adjustment rack 67 will cause the deflection amplitude of the eccentric frame 64 to change, and then the eccentric frame 64 drives the limit rack 68 to reciprocate on the fixed frame 61, which can increase the movement amplitude of the screen rod 610, thereby increasing the discharge amount from the water tank 11 into the water pipe.
