[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a layered rice breeding rack, which has the following beneficial effects:

[0015] This tiered rice breeding rack is designed with a base plate, connectors, support rods, horizontal plates, toothed plates, placement plates, and limiting baffles. In use, the support rods are inserted into the connectors and secured with bolts. The placement plates are then passed through four support rods and two toothed plates. Pressing the pressing plate to one side while simultaneously shaking the rocker counter-clockwise lowers the placement plates. The sleeves at both ends of the limiting baffle are then fitted onto the tops of the support rods and secured with bolts. This design facilitates easy disassembly and assembly, as well as transport and handling. The rack also incorporates gears, shafts, rockers, mounting slots, springs, toothed plates, and pressing plates. Pressing the pressing plate to one side separates the toothed plates from the gears. Shaking the rocker adjusts the distance between the upper and lower placement plates. After adjustment, releasing the pressing plate allows the spring's return force to engage the toothed plates in the gear slots for fixation. This allows for easy adjustment of the rack's spacing and significantly improves the device's practicality. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: It includes a base plate 1, with four fixed insertion seats 2 at the four corners of the upper surface of the base plate 1. Support rods 3 are inserted into the interior of the insertion seats 2. The bottom of the outer walls of two adjacent support rods 3 are fixedly connected by a horizontal plate 4. A toothed plate 5 is fixedly installed in the middle of the upper surface of the horizontal plate 4. A placement plate 6 is installed on the surface of the support rods 3. Gears 7 are installed at both ends inside the placement plate 6. Two gears 7 are fixedly connected by a rotating shaft 8. One end of the rotating shaft 8 rotatably passes through the placement plate 6 and is fixedly connected to a rocker arm 9. The interior of the placement plate 6 is open... An installation slot 10 is provided, and a spring 11 is fixedly installed inside the installation slot 10. One end of the spring 11 is fixedly connected to a toothed plate 12, and a pressing plate 13 is fixedly installed on the upper surface of the toothed plate 12. Through the cooperation of gear 7, rotating shaft 8, rocker arm 9, installation slot 10, spring 11, toothed plate 12 and pressing plate 13, when in use, pressing the pressing plate 13 to one side will cause the toothed plate 12 to separate from the gear 7. Then, the distance between the upper and lower placement plates 6 can be adjusted by shaking the rocker arm 9. After adjustment, the pressing plate 13 can be released. The spring 11's rebound force pushes the toothed plate 12 into the gear groove for fixed positioning, thus facilitating user adjustment of the breeding rack spacing and effectively improving the device's practicality. Limiting baffles 14 are installed at one end of each of the two support rods 4. Through the coordinated arrangement of the base plate 1, insertion seat 2, support rods 3, horizontal plate 4, toothed plate 5, placement plate 6, and limiting baffles 14, in use, the support rods 3 are inserted into the insertion seat 2 and fixed with fastening bolts. Then, the placement plate 6 passes through all four support rods 3 and two toothed plates 5 simultaneously, and then... Press the pressing plate 13 on one side and shake the rocker arm 9 counterclockwise to lower the placement plate 6. Then, put the sleeves at both ends of the bottom of the limiting baffle 14 onto the top of the support rod 3 and tighten the fastening bolts to fix them. This makes it convenient for users to disassemble and assemble the breeding rack, and also facilitates the handling and transportation of the breeding rack. The plug 3 is fixed to the support rod 4 by the fastening bolts. The breeding tray is placed on the upper surface of the placement plate 7. The toothed plate 6 is meshed with the gear 8. The bottom four corners of the base plate 1 are fixedly installed with self-locking casters 15.

[0023] In summary, this tiered rice breeding rack, through the coordinated arrangement of a base plate 1, a connector 2, support rods 3, a horizontal plate 4, a toothed plate 5, a placement plate 6, and a limiting baffle 14, allows for easy operation. During use, the support rods 3 are inserted into the connectors 2 and secured with bolts. The placement plate 6 is then passed through all four support rods 3 and two toothed plates 5. The pressing plate 13 is then pressed to one side while simultaneously rocking the rocker arm 9 counter-clockwise to lower the placement plate 6. Finally, the sleeves at both ends of the limiting baffle 14 are fitted over the tops of the support rods 3 and secured with bolts. This design facilitates easy operation of the breeding rack for the user. The device is easy to disassemble and assemble, and facilitates the handling and transportation of the breeding rack. It is designed with gear 7, rotating shaft 8, rocker arm 9, mounting groove 10, spring 11, toothed plate 12 and pressing plate 13 in cooperation. When in use, pressing the pressing plate 13 to one side will cause the toothed plate 12 to separate from the gear 7. Then, the distance between the upper and lower placement plates 6 can be adjusted by shaking the rocker arm 9. After adjustment, the pressing plate 13 is released and the rebound force of the spring 11 pushes the toothed plate 12 into the gear groove for fixed positioning. This makes it convenient for users to adjust the spacing of the breeding rack and effectively improves the practicality of the device.
