Abstract
Description
Technical Field
[0001] The present application relates to the technical field of seedling transplanting, and in particular to a seedling lifting device. Background Art
[0002] In afforestation, seedling lifting is a crucial step. As an indispensable tool in the process of seedling planting and transplanting, the performance of the seedling lifting device directly affects the survival rate and growth quality of the seedlings. However, traditional seedling lifting devices often face some technical challenges during the digging process, the most prominent of which is the difficulty in accurately controlling the digging depth.
[0003] Existing seedling lifting devices mainly rely on manual operation or simple mechanical control to achieve the digging action when digging. This method often has the problem of insufficient precision, because changes in factors such as soil texture and humidity will affect the digging depth. When digging too deep, it will not only waste a lot of soil and energy, increase the cost of seedling lifting, but also cause unnecessary damage to the root system of the seedlings, affecting their growth potential. On the other hand, if the excavation is too shallow, the roots of the seedlings may not be fully dug out, which will result in poor seedling lifting results, and even require the seedling lifting operation to be repeated, further increasing the workload and cost.

DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.
[0026] Example:
[0027] See also Figure 1 , Figure 4 A seedling lifting device includes a seedling lifting shovel 1, wherein the seedling lifting shovel 1 includes a handle 11, a threaded column 12, a rod body 13 and a shovel head 14.
[0028] Among them, the design of the seedling shovel 1 can be suitable for operators of different heights, and the handle 11 is located at the top of the seedling shovel, which is convenient for the operator to hold. Its bottom end is firmly connected to the top of the threaded column 12 by welding to ensure that it will not loosen or fall off during the seedling lifting process. The design of the handle 11 conforms to the principle of ergonomics, and the surface is covered with anti-skid material to provide a comfortable grip experience and effectively prevent slipping in a wet or muddy environment. The threaded column 12 is located between the handle 11 and the rod body 13, and plays a role in connecting and adjusting the length. Its outer wall is provided with fine threads, which match the threads on the inner wall of the rod body 13 to achieve a stable threaded connection. The rod body 13 is the main part of the seedling shovel, which is responsible for transmitting the operator's power to the shovel head 14 for digging. The outer wall of the rod body 13 is provided with an external thread 242, which fits the inner wall of the sleeve 232 in the adjustment mechanism 2 to achieve the initial fixation of the length of the seedling shovel. The inner wall of the rod body 13 is provided with an internal thread, which is threadedly connected to the outer wall of the threaded column 12. The overall length of the seedling shovel 1 can be adjusted by rotating the threaded column 12. The shovel head 14 is located at the bottom of the seedling shovel and is the part that directly contacts the soil. The top of the shovel head 14 is welded to the bottom end of the rod body 13 to ensure a firm connection. Its outer wall fits the "C"-shaped groove of the base 211 to further stabilize the position of the shovel head 14 and prevent shaking during the excavation process. The shovel head 14 is made of sharp and wear-resistant materials, such as high-carbon steel or hard alloy, to ensure that it can easily cut into the soil and reduce wear during the excavation process.
[0029] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A seedling lifting device includes a seedling shovel 1 with an adjusting mechanism 2 installed on the outer wall. The adjusting mechanism 2 consists of a supporting member 21, a sliding member 22, a hinge 23 and a limiting member 24. The supporting member 21 includes a base 211, a connecting column 212 and a moon plate 213; the sliding member 22 includes a sliding groove I 221, a sliding groove II 222, a threaded head 223, a limiting ring 224 and a threaded ring 225; the hinge 23 includes two connecting blocks 231 and a sleeve 232; the limiting member 24 includes a nut 241 and an external thread 242.
[0030] Among them, the support member 21 is a key component of the seedling lifting device, and its design is intended to provide a stable support function. The base 211 fits tightly with the seedling lifting shovel 1 to ensure stable support during the seedling lifting process. The sturdy design of the connecting column 212 and the moon plate 213 further enhances the stability of the support member 21. Through the design of the sliding member 22, the connecting column 212 can be moved on the base 211 to adjust the digging angle of the seedling lifting shovel 1. This design enables the seedling lifting shovel 1 to adapt to different soil conditions and digging requirements. The hinge 23 fixedly connected to the side wall of the moon plate 213 allows the moon plate 213 to be adjusted to a certain angle relative to the seedling lifting shovel 1. This design enables the seedling lifting shovel 1 to adapt to the needs of different terrains and digging depths, thereby improving the efficiency and success rate of seedling lifting.
[0031] Among them, the sliding member 22 is a key component in the support member 21, which allows the connecting column 212 to be precisely adjusted on the base 211 to meet different digging angle requirements. The sliding grooves Ⅰ221 and Ⅱ222 opened on the base 211 facilitate the sliding of the connecting column 212 on the surface of the base 211. Through the cooperation of the threaded head 223, the limiting ring 224 and the threaded ring 225, the connecting column 212 can be installed on the base 211 and restricted to facilitate the sliding of the connecting column 212. The position of the moon plate 213 is adjusted by sliding the connecting column 212, so that the moon plate 213 forms a certain angle with the base 211, and the angle of the seedling shovel 1 can be adjusted.
[0032] Among them, the connecting column 212, the moon plate 213, the threaded head 223 and the limiting ring 224 are designed to be an integrally formed structure. This design not only improves the firmness and stability of the entire support member 21, but also simplifies the manufacturing process, reduces production costs, and can withstand a greater workload. A "C"-shaped groove is designed at one end of the base 211, and the shape of this groove matches the lifting end of the seedling lifting shovel 1, so that the lifting end of the seedling lifting shovel 1 can fit tightly in the "C"-shaped groove. This design not only enhances the connection stability between the seedling lifting shovel 1 and the support member 21, but also helps to maintain the stability and accuracy of the shovel head 14 during the lifting process.
[0033] Among them, the hinge 23 is a key component connecting the moon plate 213 and the seedling shovel 1. Its design allows the seedling shovel 1 to rotate at a certain angle relative to the moon plate 213. Through the hinged design of the connecting block 231 and the sleeve 232, the seedling shovel 1 can rotate at a certain angle relative to the moon plate 213. This design enables the seedling shovel 1 to adapt to different terrains and excavation requirements during the seedling lifting process, thereby improving the flexibility and efficiency of seedling lifting. The interior of the sleeve 232 fits with the outer wall of the rod body 13, which is convenient for limiting the seedling shovel 1. It is ensured that the seedling shovel 1 slides inside the sleeve 232.
[0034] The design of the stopper 24 facilitates the adjustment of the digging depth of the seedling lifting shovel 1, and the external thread 242 is directly provided on the outer wall of the rod body 13 and fits tightly with the inner wall of the sleeve 232. This design enables the sleeve 232 to slide within a certain range along its length direction on the seedling lifting shovel 1. The inner wall of the nut 241 is threadedly connected with the external thread 242. By simply rotating the nut 241, its position on the seedling lifting shovel 1 can be easily adjusted, thereby achieving precise control of the sliding range of the sleeve 232. This design makes the operation more flexible and convenient.
[0035] The working principle of the seedling lifting device is as follows: when in use, the connecting column 212 is slidably connected inside the sliding groove I 221, and then the position of the moon plate 213 is adjusted by using the connecting column 212, so that a certain angle is formed between the moon plate 213 and the "C"-shaped groove opened at one end of the base 211. At the same time, the seedling lifting shovel 1 adjusts the inclination angle through the hinge 23, and then is threadedly connected with the thread head 223 through the threaded ring 225, thereby fixing the position of the connecting column 212, and then by rotating the position of the nut 241, the sliding range of the rod body 13 inside the sleeve 232 is limited, thereby adjusting the depth of digging. In the process of lifting seedlings, the seedling lifting shovel 1 is inserted into the soil, and the seedlings are dug out of the soil through its sharp shovel head 14.
[0036] It should be noted that the specific model specifications of the threaded head 223 and the sleeve 232 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0037] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
