Description

Technical Field

[0001] This utility model relates to the field of distance measuring device technology, specifically to a strawberry seedling transplanting distance measuring device. Background Technology

[0002] Strawberry seedling transplanting is a crucial step in strawberry cultivation. Proper spacing ensures seedlings receive sufficient sunlight, nutrients, and growing space, thereby improving yield and quality. Traditional strawberry seedling transplanting relies mainly on manual visual estimation or simple rulers for spacing, resulting in low efficiency and uneven spacing. Furthermore, existing strawberry seedling transplanting spacing devices still have the following drawbacks: 1. Existing distance-fixing components typically use simple threaded adjustments or fixing bolts for the distance-fixing wheels. Adjustment requires repeatedly tightening or loosening multiple components, making the operation cumbersome. Furthermore, after adjustment, the wheels are prone to shifting due to vibration or external forces, affecting the distance-fixing accuracy. 2. Existing spacers typically use spacers with a fixed height, which cannot flexibly adjust the height of the spacers according to different terrains or planting needs. This means that when used on soft or uneven ground, the spacers may not make full contact with the ground, affecting the spacer's positioning effect.

[0003] Therefore, in view of this, we studied and improved the existing structure and proposed a strawberry seedling transplanting distancer. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-4A strawberry seedling transplanting spacer includes a frame 1 made of lightweight metal or high-strength plastic, forming a frame structure. Wheels 2 are rotatably mounted on the frame 1 for easy movement in the field. The wheels 2 are rotatably mounted at the bottom of the frame 1 via bearings, allowing for smooth rolling on the ground and reducing pushing resistance. A handle 101 is fixedly mounted on one side of the frame 1 for easy gripping and pushing of the spacer. A spacer assembly 3 is located below the frame 1. The spacer assembly 3 includes a movable frame 301 slidably mounted on the frame 1. Adjusting cylinders 302 are fixedly mounted on both sides of the movable frame 301. Two oppositely arranged receiving frames 303 are fixedly mounted inside the movable frame 301. A storage cylinder 304 is fixedly mounted between the two receiving frames 303. An adjusting rod 305 is slidably mounted within the adjusting cylinder 302, with one end of the adjusting rod 305 movably passing through the corresponding receiving frame 303. The adjusting cylinder 302 is rotatably fitted with a nut 308 at one end, and the adjusting rod 305 is threaded to connect with the nut 308. A connecting rod 306 is fixedly fitted on the adjusting rod 305, and a spring 307 is fitted on the adjusting rod 305. One end of the spring 307 is fixedly connected to the connecting rod 306, and the other end is fixedly connected to the corresponding support frame 303, so that the distance wheel 309 always maintains elastic contact with the ground during movement, avoiding inaccurate distance due to uneven ground. A bearing is rotatably embedded in the connecting rod 306, and the distance wheel 309 is movably mounted on the bearing. A threaded rod 3010 is fixedly fitted on one side of the distance wheel 309 and movably passes through the bearing. A nut 3011 is threadedly fitted on the threaded rod 3010, and one side of the nut 3011 abuts against the bearing. A rubber pad is fixedly fitted on one side of the nut 3011.

[0024] The spacing wheel 309 is replaceable in size and features a modular design. It allows for quick assembly and disassembly via a threaded rod 3010 and bearing, and is equipped with spare wheel sets of different diameters. Replacing the spacing wheel 309 allows for adaptation to different plant spacing requirements. The circumferential surface of the spacing wheel 309 is evenly distributed with indentation teeth, the spacing of which precisely matches the standard plant spacing for strawberry cultivation, ensuring accurate correspondence between the indentation marks and the actual planting position.

[0025] The specific working structure of the fixed-distance wheel 309 is as follows: When the device is pushed, the traveling wheel 2 drives the frame 1 forward. During the rolling process of the fixed-distance wheel 309 in contact with the ground, the indentation teeth on its surface will periodically press into the soil to form equidistant marks. The sliding stroke of the adjusting rod 305 is linearly related to the distance between the fixed-distance wheels 309. The distance adjustment accuracy of ±1cm can be achieved by adjusting the thread accuracy of the nut 308.

[0026] 1. Adjust the spacing between the fixed-distance wheels Pull the moving plate 402 of the brake assembly 4 so that the lever 401 leaves the groove of the adjusting rod 305.

[0027] Rotate nut 308. Since the thread is connected to nut 308, the adjusting rod 305 slides in the adjusting cylinder 302, causing the connecting rod 306 on the adjusting rod 305 to move, thereby enabling the spacer wheel 309 to move and adjust to the required plant spacing.

[0028] After adjustment, stop rotating nut 308 to prevent the adjusting rod 305 from moving. At the same time, the locking rod 401 of the braking assembly 4 automatically engages with the groove of the adjusting rod 305 under the action of spring 403, further locking the position and preventing loosening.

[0029] 2. Installation and fixing of the spacer wheel 309 The fixed-distance wheel 309 is rotatably mounted on the connecting rod 306 via a bearing, and can rotate freely to reduce friction.

[0030] After the threaded rod 3010 passes through the bearing, it is locked with nut 3011, and friction is increased by rubber pads to ensure that the spacer wheel 309 will not fall off or shift during operation. Please see Figure 1-4 The storage cylinder 304 is provided with a braking assembly 4 that brakes two adjusting rods 305; the braking assembly 4 includes two locking rods 401 that move through the storage cylinder 304, and the locking rods 401 are engaged with the corresponding adjusting rods 305. A moving plate 402 is fixedly provided between the two locking rods 401, and a spring 403 is fixedly provided between the moving plate 402 and the storage cylinder 304.

[0031] Please see Figure 1-2 A position adjustment component 5 is provided between the frame 1 and the movable frame 301, and the position adjustment component 5 adjusts the position of the distance fixing component 3. The position adjustment component 5 includes a bidirectional threaded rod 501 rotatably mounted on the frame 1, and two opposing sliders 502 are threadedly sleeved on the bidirectional threaded rod 501. The sliders 502 are limited and slidably connected to the frame 1. The bidirectional threaded rod 501 is provided with positive thread and negative thread, and the positive thread and negative thread are opposite. One slider 502 is provided with a positive thread hole for rotating the positive thread, and the other slider 502 is provided with a negative thread hole for rotating the negative thread. A connecting clip 1 is fixedly provided at the bottom of the slider 502, and two connecting clips 2 are fixedly provided at the top of the movable frame 301. A push rod 503 is hinged between the corresponding connecting clips 1 and connecting clips 2. A rotating block 504 is rotatably provided on one side of the frame 1 to drive the bidirectional threaded rod 501 to rotate. A bolt 505 is movably passed through the rotating block 504, and one end of the bolt 505 is threadedly connected to the frame 1.

[0032] Height adjustment steps Loosen bolt 505, rotate block 504 to drive bidirectional threaded rod 501 to rotate, so that two sliders 502 move towards or away from each other along frame 1.

[0033] The slider 502 pushes the movable frame 301 up or down via the push rod 503, thereby adjusting the ground clearance of the fixed-distance wheel 309.

[0034] After adjusting to the appropriate height, tighten bolt 505 to secure rotating block 504 and prevent the height adjustment mechanism from loosening.

[0035] The working principle of this utility model: 1. Preparation Plant spacing adjustment: According to the required plant spacing for strawberry planting (e.g., 15cm, 20cm, 25cm, 30cm), rotate nut 308 to make the adjusting rod 305 slide inside the adjusting cylinder 302, driving the spacer wheel 309 to move to the target spacing. After adjustment, the locking rod 401 of the braking assembly 4 automatically engages with the groove of the adjusting rod 305 under the action of spring 403, locking the position and preventing loosening.

[0036] Height Adjustment: Loosen bolt 505, rotate rotating block 504 to drive bidirectional threaded rod 501 to rotate, causing slider 502 to move. Adjust the height of moving frame 301 by push rod 503 to ensure that fixed distance wheel 309 is stably in contact with the ground. After adjustment, tighten bolt 505 to fix rotating block 504.

[0037] Replacement of the spacer wheel: If it is necessary to adjust the plant spacing range, loosen nut 3011 and replace it with a spacer wheel 309 of a different diameter (such as D20-25cm specification suitable for 25cm plant spacing). After tightening nut 3011, the rubber pad provides appropriate frictional damping to ensure stable rotation of the spacer wheel.

[0038] 2. Transplanting with fixed spacing Marking formation: Pushing handle 101 causes the walking wheel 2 to drive the frame 1 forward. When the fixed-distance wheel 309 rolls, its circumferentially distributed indentation teeth periodically press into the soil, forming equidistant marks with a depth of 1-2cm. Spring 307 (elastic force 8-12N) ensures that the fixed-distance wheel always keeps in contact with the ground, adapting to uneven terrain.

[0039] Synchronous positioning: The bidirectional threaded rod 501 adjustment mechanism ensures that the two fixed-distance wheels 309 move in parallel, with a row spacing error of ≤±1cm. Operators transplant strawberry seedlings according to the markings, and the uniformity of plant spacing is significantly better than that of manual visual inspection.

[0040] 3. Adaptive adjustment mechanism Elastic compensation: Spring 307 continuously applies pressure, causing the fixed wheel 309 to float automatically when working on uneven ground, avoiding omission of markings due to local bulges or depressions.

[0041] Anti-loosening design: Nut 2 3011 presses the bearing with a rubber pad, which allows the spacer wheel to rotate freely and prevents the threads from loosening due to field vibration.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
