Description

Technical Field

[0001] This utility model relates to the technical field of ladders and stools for seedling ponds, specifically a simple ladder and stool for operating seedling ponds. Background Technology

[0002] Seedling beds are places specifically designed to provide seedling cultivation services for plant cultivation. These places typically possess professional facilities and technologies, enabling them to efficiently cultivate healthy and robust plant seedlings for farmers to transplant into the fields for subsequent growth. Tobacco seedlings require seedbed management during the seedling stage, including thinning, watering, fertilizing, and leaf pruning. Seedling bases play a crucial role in the agricultural production chain. They not only improve the survival rate and growth rate of seedlings but also provide convenience for farmers, helping them save a significant amount of time and energy. In addition, bases plan and cultivate different varieties of tobacco seedlings according to market demand and planting season to meet the diverse needs of farmers. However, existing methods for fertilizing and thinning seedlings in seedling beds require operation within the seedling bed aisle. The floating trays are lifted out of the bed before adding fertilizer or thinning. While the floating trays on both sides of the seedling bed are easy to lift out, it is difficult to lift the tobacco seedlings in the middle of the bed. Furthermore, the tobacco seedlings in the middle of the bed are also difficult to pull out during transplanting. Therefore, improvements are needed to address these issues to meet practical usage requirements. Utility Model Content

[0019] 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.

[0020] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a simple ladder stool for operating a seedling pond, comprising a main ladder body 1 and a moving component 4. Support legs 2 are provided at both ends of the lower part of the main ladder body 1, and a stabilizing crossbar 3 is installed at the middle of the inner side of each support leg 2. The moving component 4 is provided at the lower end of the support leg 2, and the moving component 4 includes a limiting frame 401, a limiting groove 402, a servo motor 403, a lead screw 404, a movable slider 405, and a receiving frame 406. Limiting grooves 402 are provided on both sides inside the limiting frame 401, and a servo motor 403 is installed at one end of the limiting frame 401. The front end of the servo motor 403... A lead screw 404 is connected, and a movable slider 405 is provided on the outside of the lead screw 404. A receiving frame 406 is installed on the outside of the movable slider 405. There are two limiting frames 401, and the two limiting frames 401 are symmetrically arranged on both sides of the lower end of the main ladder 1 with the central axis of the front of the main ladder 1. The external dimensions of the movable slider 405 are adapted to the internal dimensions of the limiting frame 401, and the movable slider 405 is slidably connected to the limiting frame 401 through the lead screw 404. The internal dimensions of the receiving frame 406 are adapted to the external dimensions of the limiting frame 401, and the inner surface of the receiving frame 406 is tightly fitted to the outer surface of the limiting frame 401.

[0021] When using the simple ladder stool for operating the seedling pond, such as Figure 1 and Figure 3As shown, the entire device is first assembled and connected. The servo motor 403 is fixedly installed on the front end of the limiting frame 401 by fastening bolts. The output shaft of the servo motor 403 is connected to the lead screw 404 through a coupling. The operation of the servo motor 403 drives the lead screw 404 to rotate, so that the movable slider 405 connected to the outside of the lead screw 404 slides inside the front end of the limiting frame 401. The external dimensions of the mounting blocks added on both sides of the movable slider 405 are adapted to the internal dimensions of the limiting grooves 402 opened on both sides of the limiting frame 401. The mounting blocks and fastening bolts are used to fix the receiving frame 406 on the outside of the movable slider 405, so that the movable slider 405 moves and drives the receiving frame 406 to adjust the position of use, thereby adjusting the position of the main ladder 1 at the upper end of the receiving frame 406.

[0022] Meanwhile, a storage assembly 5 is provided at the upper end of the main ladder body 1. The storage assembly 5 includes a receiving slide 501, a limiting crossbar 502, a receiving slider 503, and a limiting through hole 504. The limiting crossbar 502 is installed inside the receiving slide 501, and the receiving slider 503 is connected inside the receiving slide 501. The limiting through hole 504 is opened in the middle of the receiving slider 503. The storage assembly 5 also includes a support leg 505, an operating platform 506, and a rubber pad 507. At the same time, the receiving slider 503 has a supporting leg 505, an operating platform 506, and a rubber pad 507. The end is equipped with a support leg 505, and an operating table 506 is provided on the upper end of the support leg 505. A rubber pad 507 is added to the upper end of the operating table 506. The internal dimensions of the receiving groove 501 are adapted to the external dimensions of the receiving slider 503. The receiving slider 503 is embeddedly connected to the main ladder body 1 through the receiving groove 501. The internal dimensions of the limiting through hole 504 are adapted to the external dimensions of the limiting crossbar 502. The limiting crossbar 502 is connected to the receiving slider 503 through the limiting through hole 504.

[0023] After the device is assembled, the PLC controller installed externally adjusts the internal components. The limiting crossbar 502 is fixedly installed in the receiving slide groove 501 inside the main ladder body 1 using fastening bolts. The internal dimensions of the receiving slide groove 501 are compatible with the external dimensions of the receiving slider 503 installed at the lower end of the support leg 505. Furthermore, the internal dimensions of the limiting through hole 504 inside the receiving slider 503 are compatible with the external dimensions of the limiting crossbar 502. This, in conjunction with the receiving slider 503, increases the stability of the support leg 505 during movement, thereby preventing positional deviation of the operating table 506 during movement. The operating table 506 is used to place fertilizer, seedlings, etc., and the rubber pad 507 is used to increase the friction during the placement process. Then, the servo motor 403 drives the lead screw 404 to rotate, so that the movable slider 405 connected to the outside of the lead screw 404 slides at the front end inside the limit frame 401. The receiving frame 406 is fixedly installed on the outside of the movable slider 405 by the mounting block and fastening bolts. This allows the movable slider 405 to move and drive the receiving frame 406 to adjust its position, thereby adjusting the position of the main ladder 1 at the top of the receiving frame 406 to meet the actual use needs. This is the working principle of the simple ladder stool used for seedling pond operation.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
