[0002] Rice cultivation has a long history in my country. The rice planting industry is mainly distributed in the Asian monsoon region. The cultivation of rice in the monsoon region has a history of about 7,000 years. Rice is the main crop loved by local people, and the rice produced accounts for the vast majority of the world's total rice production. In the process of rice planting, when transporting seedlings from other places to farmland, a transfer device is needed to transport the seedlings. In the process of transporting seedlings, the seedling trays are usually placed in layers in the transfer box.

[0003] However, the existing rice seedling transfer device lacks stability. When the seedlings are transferred, the seedling tray in the transfer box is easily shaken due to the uneven road surface, causing the seedlings to fall from the seedling tray. At the same time, the existing transfer device cannot adjust the height of the seedling tray, which makes it difficult for the staff to take the seedling tray at the bottom of the transfer box. In order to solve the above-mentioned problems, the utility model provides a rice seedling transfer device with a stable structure. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0019] like Figure 1-5 As shown, a rice seedling transfer device with a stable structure proposed in an embodiment of the utility model includes a base plate 1, a transfer frame 2 is fixedly installed on the top of the base plate 1, a universal wheel 201 is arranged at the bottom of the transfer frame 2, and a box cover 202 is also arranged on the top of the transfer frame 2, and it is characterized in that: a plurality of seedling boxes 3 are slidably installed between the two sides of the inner wall of the transfer frame 2, and the plurality of seedling boxes 3 are arranged up and down, a lifting device 4 is arranged at the bottom of the interior of the transfer frame 2, and a limiting component 5 is arranged on the left and right sides of the transfer frame 2.

[0020] When in use, the equipment is moved to a specified position via the universal wheels 201, and then the box cover 202 is opened, and the heights of the plurality of seedling boxes 3 are adjusted using the lifting device 4, so that the staff can take the seedling boxes 3. When there are enough seedlings placed in one of the seedling boxes 3, the lifting device 4 is used again to drive the seedling box 3 to descend and move it to the bottom of the transfer frame 2, so that more seedling boxes 3 can be placed in the transfer frame 2. Finally, the seedling box 3 is limited and fixed using the limiting assembly 5 to prevent the seedling box 3 from shaking in the transfer frame 2 during movement, thereby improving the stability of the seedling box 3.

[0021] like Figure 3 As shown, in some embodiments, the lifting device 4 includes four screw rods 41 symmetrically distributed and rotatably installed on the top of the base plate 1, and the outer surfaces of the four screw rods 41 are threadedly installed with multiple lifting plates 42, one side of the multiple lifting plates 42 is fixedly connected to one side of the seedling box 3, and a driving assembly 43 is also provided on the top of the base plate 1.

[0022] When the height of the seedling box 3 needs to be adjusted, the driving assembly 43 drives the four screw rods 41 to rotate synchronously, thereby driving the multiple lifting plates 42 to continuously rise, and then driving the multiple seedling boxes 3 to continuously rise along the inner wall of the transfer frame 2, and vice versa.

[0023] like Figure 1and Figure 5 As shown, in some embodiments, the limiting assembly 5 includes a plurality of fixed cylinders 51 respectively fixedly installed on the left and right sides of the transfer frame 2, and a limiting rod 52 is inserted in each of the plurality of fixed cylinders 51. The limiting rods 52 respectively pass through one side of the transfer frame 2 and one side of the seedling box 3. A pressure plate 53 is fixedly sleeved on the outer surface of the limiting rod 52. A reset spring 54 is sleeved on the outer surface of the limiting rod 52, and the pressure plate 53 and the reset spring 54 are both located in the fixed cylinder 51.

[0024] When the seedling box 3 needs to be limited and fixed, the limit rod 52 is first pulled to be drawn out from the transfer frame 2, and at the same time, the pressure plate 53 is driven to squeeze the return spring 54. When the seedling box 3 drops to a suitable position, the limit rod 52 is released, and the rebound force of the return spring 54 is used to drive the limit rod 52 to move, so that the limit rod 52 is inserted into the transfer frame 2 and the seedling box 3, thereby realizing the limit fixation of the seedling box 3.

[0025] like Figure 3 and Figure 4 As shown, in some embodiments, the driving assembly 43 includes a servo motor 431 fixedly installed inside the base plate 1, and the output shaft of the servo motor 431 is fixedly connected to one end of one of the screw rods 41, and the outer surface of one of the screw rods 41 is fixedly sleeved with a driving gear 432, and the outer surfaces of the other three screw rods 41 are fixedly sleeved with driven gears 433, and the driving gear 432 and the driven gear 433 are connected by a toothed belt 434.

[0026] When it is necessary to drive the four screw rods 41 to rotate synchronously, the servo motor 431 is started, and the output shaft of the servo motor 431 drives one of the screw rods 41 to rotate, thereby driving the driving gear 432 to rotate. Since the driving gear 432 and the driven gear 433 are connected through the toothed belt 434, when the driving gear 432 rotates, it will drive the driven gear 433 to rotate synchronously, thereby driving the four screw rods 41 to rotate synchronously.

[0027] like Figure 2 As shown, in some embodiments, a partition 6 is fixedly installed between the two sides of the inner wall of the transfer frame 2, and the partition 6 is located at the bottom of the seedling box 3.

[0028] The partition plate 6 can prevent the soil falling from the seedling box 3 from falling onto the bottom plate 1 , thereby affecting the normal operation of the driving assembly 43 .

[0029] like Figure 1 As shown, in some embodiments, a plurality of air holes 7 are provided on the outer surface of the transfer frame 2.

[0030] The multiple air holes 7 can allow air to circulate in the transfer frame 2, thereby preventing the temperature in the transfer frame 2 from being too high and affecting the normal growth of the seedlings.

[0031] Finally, the most important contribution of the utility model is: the height of the seedling box 3 is adjusted by the lifting device 4, so that the staff can more conveniently take the seedling box 3 located at the bottom of the transfer frame 2, and then the limiting component 5 is used to limit and fix the seedling box 3 in the transfer frame 2, which effectively improves the stability of the seedling box 3 during transportation and prevents the seedling box 3 from shaking during transportation.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
