Description

Technical Field

[0001] This utility model relates to the field of crop seedling technology, and in particular to a crop seedling transplanting locator. Background Technology

[0002] Crop seedlings are seedlings that have grown to a certain stage after the seeds of crops germinate. They mainly have stems and leaves and are a key stage in the crop growth cycle from seed germination to transplanting. Their growth status directly affects subsequent growth, development, yield and quality. In production, vigorous seedlings are often cultivated through meticulous seedling management to lay the foundation for high and stable crop yields.

[0003] The crop seedling transplanter is a practical tool used in agricultural planting, primarily for accurately determining the position of seedlings during transplanting. It comes in various types, with a common one being an inverted U-shaped structure. For example, the inverted U-shaped transplanter consists of an inverted U-shaped rod, a handle, a plug-in base or outer sleeve, and an inner sleeve. During operation, the spacing is adjusted according to the required plant spacing. A single person can hold the handle and rotate it to accurately position the plant spacing, facilitating subsequent planting and sowing. This type of tool greatly improves the accuracy of seedling transplanting, eliminating the tediousness and inaccuracies of traditional manual measurement and positioning. It helps to standardize seedling layout, ensure reasonable crop growth space, improve transplanting efficiency, and reduce labor intensity. It is applicable to the transplanting of seedlings for various crops such as vegetables, tobacco, and fruit trees. While playing a crucial role in the work, the anchor rods and plug-in bases of the positioning device are difficult to insert or loosen in heavy, compacted, or gravelly soils, leading to positioning failure. In sandy soils, the positioning device is prone to displacement after being fixed due to the loose soil. In existing technologies, the front end of the anchor rod is changed to a spiral drill bit shape with a hard alloy coating to enhance its soil-breaking ability. The middle of the rod is equipped with a ring-shaped serrated barb. After the anchor rod is inserted into the soil, rotating the anchor rod causes the barb to embed into the soil, forming a gear-like interlocking effect to prevent it from being pulled up and loosened. If the positioning device base or pole is of a fixed length, frequent equipment replacement or manual measurement is required when the spacing needs to be changed. This is especially cumbersome when planting multiple varieties in contiguous areas, thus reducing work efficiency. Utility Model Content

[0030] 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.

[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a crop seedling transplanting locator, comprising a fixed rod 1, a telescopic mechanism 3 installed at the bottom of the fixed rod 1 for telescopic extension and retraction of the device, and a positioning mechanism 2 installed at the bottom of the telescopic mechanism 3 for positioning the device; the telescopic mechanism 3 includes two first sliding rods 301, which are respectively fixedly connected to the left and right ends of the bottom of the fixed rod 1; a second sliding rod 302 is slidably connected to the bottom of the first sliding rods 301; a second threaded rod 304 is rotatably connected to the middle of the bottom end of the fixed rod 1; a connecting circular plate 306 is threadedly connected to the outer side of the second threaded rod 304; and connecting bottoms are fixedly connected to the left and right ends of the connecting circular plate 306. A connecting rod 305 is fixedly connected to the bottom of the connecting base plate 307. A connecting round rod 303 is fixedly connected to the bottom of the connecting rod 305. A driving assembly 308 is installed on the top of the second threaded rod 304. The driving assembly 308 includes a connecting short rod 3081, which is fixedly connected to the top of the second threaded rod 304. A fixing plate 3083 is fixedly connected to the top of the connecting short rod 3081. A turntable 3082 is fixedly connected to the outside of the fixing plate 3083. The left and right ends of the connecting round rod 303 are fixedly connected to the adjacent sides of the two second sliding rods 302, respectively. A handle 5 is fixedly connected to both the left and right ends of the fixing rod 1. The installation of the handle 5 facilitates the use of this device.

[0032] Specifically, the rotating turntable 3082 drives the second threaded rod 304 to rotate via the fixed plate 3083 and the connecting short rod 3081. Since the second threaded rod 304 is threadedly connected to the connecting circular plate 306, this causes the connecting circular plate 306 to move up and down along the second threaded rod 304. The connecting circular plate 306 further drives the connecting circular rod 303 to move via the connecting base plate 307 and the connecting thin rod 305. Since the connecting circular rod 303 is connected to the second sliding rod 302, this allows the second sliding rod 302 to slide on the first sliding rod 301, thereby achieving the telescopic effect of the telescopic mechanism 3. After adjusting the length of the telescopic mechanism 3, it is convenient for subsequent processes to be carried out.

[0033] Reference Figure 1 , Figure 3 and Figure 5 The positioning mechanism 2 includes a mounting ring 201, which is installed at the bottom of the second sliding rod 302. Multiple second sliding tubes 203 are fixedly connected at equal intervals to the bottom of the mounting ring 201. A first sliding tube 202 is slidably connected to the bottom of each second sliding tube 203. A connecting short column 205 is fixedly connected to the bottom of the first sliding tube 202. A conical head 207 is fixedly connected to the bottom of the connecting short column 205. A connecting rod 206 is rotatably connected to the middle of the connecting short column 205. A spring 204 is installed on the inner side of the second sliding tube 203. An installation assembly 208 is installed on the outer top of the mounting ring 201. The installation assembly 208 includes two first threaded rods 2081, which are rotatably connected to the left and right ends of the mounting ring 201, respectively. A fixed circular plate 2082 is fixedly connected to the opposite side of each of the two first threaded rods 2081. The installation of the installation assembly 208 makes the positioning mechanism 2 more securely installed.

[0034] Specifically, by rotating the fixed circular plates 2082 on the two first threaded rods 2081, the mounting ring 201 is placed in the appropriate position. Then, the device is placed at the positioning point. When the conical head 207 contacts the ground, the device is pressed down. At this time, the first sliding tube 202 slides upward in the second sliding tube 203 and compresses the spring 204. The connecting short column 205 rises accordingly. Through the rotational connection of the connecting rod 206, it is ensured that the device can be stably installed and adapt to various different ground surfaces. The conical head 207 is pressed continuously until the shovel 6 can be used to transplant seedlings. Through the above process, the device achieves the function of effective positioning on uneven ground.

[0035] Reference Figure 1 , Figure 2 and Figure 3A connecting ring 8 is provided at the bottom center of the fixed rod 1. A connecting block 7 is fixedly connected to both the left and right ends of the connecting ring 8. The middle part of the connecting block 7 is connected to the bottom of the second sliding rod 302. A shovel 6 is fixedly connected to the bottom of the connecting ring 8. A limit rod 4 is fixedly connected to both the left and right sides of the bottom center of the fixed rod 1. The outer side of the limit rod 4 is slidably connected to the middle part of the connecting circular plate 306.

[0036] Specifically, the installation of the connecting block 7 facilitates the installation of the shovel cylinder 6, and the installation of the limiting rod 4 facilitates the movement of the connecting base plate 307.

[0037] Working principle: Rotating the turntable 3082 causes the second threaded rod 304 to rotate via the fixed plate 3083 and the connecting short rod 3081. Since the second threaded rod 304 is threadedly connected to the connecting round plate 306, the connecting round plate 306 moves up and down along the second threaded rod 304. The connecting round plate 306 moves the connecting round rod 303 via the connecting base plate 307 and the connecting thin rod 305. Since the connecting round rod 303 is connected to the second sliding rod 302, the second sliding rod 302 slides on the first sliding rod 301, realizing the extension and retraction of the telescopic mechanism 3. After adjusting the length of the telescopic mechanism 3, it is convenient for subsequent processes.

[0038] Rotate the fixed circular plate 2082 of the two first threaded rods 2081 to install the mounting ring 201 in a suitable position. Then place the device at the positioning point. After the conical head 207 contacts the ground, press the device down. The first sliding tube 202 will slide upward in the second sliding tube 203 and compress the spring 204. The connecting short column 205 will rise accordingly. Through the rotation connection of the connecting rod 206, the device can be stably installed and can adapt to different ground. By continuously pressing the conical head 207 until the shovel 6 can transplant seedlings, the above process achieves the effect of positioning the device on unbalanced ground.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
