Description

Technical Field

[0001] This utility model relates to the field of seedling transplanting technology, specifically to a vegetable seedling transplanter with adjustable row spacing. Background Technology

[0002] Traditional direct seeding of vegetables is susceptible to environmental factors, resulting in uneven germination, low survival rates, and cumbersome field management. With the development of facility agriculture, centralized seedling raising can cultivate robust and high-quality seedlings, but transplanting is still necessary to connect with field planting. Vegetable transplanting optimizes growing space, extends the effective growth cycle, enhances stress resistance, and facilitates standardized field management and multiple cropping, thereby improving yield, quality, and land utilization. The row spacing adjustment mechanism for transplanters, disclosed in Publication No. CN222706997U, has the following advantages: by rotating the lead screw, the adjusting block moves, which in turn moves the second slider, which in turn moves the first slider, which in turn moves the seedling feeder, thus changing the distance between the feeders and meeting the different row spacing requirements of different crops, improving versatility. However, it has the following drawbacks: by driving the lead screw to adjust the spacing of multiple feeders, it can only achieve equal enlargement or reduction of the spacing between each feeder, and cannot flexibly set non-equidistant personalized spacing according to the differentiated cultivation needs of different crops. For scenarios that require planting in combination with specific plant and row spacing or intercropping multiple crops in the same field, this adjustment method has obvious limitations and is difficult to adapt to diverse planting needs.

[0014] 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.

[0015] like Figures 1-5 As shown, this utility model provides the following technical solution: Example 1: An adjustable row spacing vegetable seedling transplanter includes a frame 1 and support frames 2 installed on both sides of the top of the frame 1. Multiple sliding plates 12 are slidably engaged at the inner end of the frame 1. Limiting rings 13 are fixedly connected to the inner end of the circular holes of the sliding plates 12. Fixed plates 14 are fixedly connected to the bottom edge of the sliding plates 12. A locking rod 15 is hinged to one end of the sliding plate 12. A foot pedal 16 is fixedly connected to the bottom end of the locking rod 15. Springs 17 are fixedly connected between the foot pedal 16 and the fixed plate 14. Locking rods 10 are engaged with locking rods 15. Several conical plates 11 are fixedly connected to the bottom of the frame 1. Sliding grooves 101 are opened on both sides of the frame 1, and the sliding plates 12 are slidably engaged in them. Locking rods 10 and locking rods 15 are engaged with each other and distributed on the outer wall of the frame 1.

[0016] Among them, the conical plate 11 is fixed to the bottom of the frame 1 and inserted into the soil to enhance the stability of the equipment support and prevent displacement during transplanting; The second clamp 10 and the first clamp 15 are interlocked and installed on the outer wall of the frame 1. They can lock the adjusted sliding plate 12 to prevent the sliding plate 12 from shifting during transplanting and ensure stable row spacing. The grooves 101 on both sides of the frame 1 allow the sliding plate 12 to slide and engage, providing a directional track for adjusting the spacing of the sliding plate 12 and ensuring the smoothness and accuracy of the row spacing adjustment.

[0017] In use, based on the planting row spacing of the target vegetable variety (the frame 1 is inserted into the field through the conical plate 11, and the row spacing is aligned by visual inspection), the sliding plate 12 is pushed along the sliding groove 101 on both sides of the frame 1 to precisely adjust the spacing between adjacent sliding plates 12; after the spacing is calibrated, the foot pedal 16 is stepped on to drive the locking rod 15 to rotate around the hinge point, so that the locking rod 15 and the locking rod 10 preset on the outer wall of the frame 1 form a snap connection, the spring 17 elastically resets and applies a pre-tightening force to the foot pedal 16 to lock and position the sliding plate 12; the conical plate 11 at the bottom of the frame 1 is inserted into the field soil to improve the overall support stability of the equipment and complete the standardized adjustment of the transplanting row spacing, which can also be used to transplant crops with non-equidistant arrays.

[0018] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a connecting plate 21 fixedly connected to the inner end of the support frame 2; two connecting strips 22 connected from top to bottom between the connecting plates 21; cylinders 23 provided at both ends of the connecting strips 22; limit grooves 201 penetrating through the two connecting strips 22; an inner groove 202 provided in the middle of the limit groove 201; a transplanting cylinder 3 slidably inserted into the inner ring of the limit ring 13; a vertical rod 31 fixedly connected to the top of the transplanting cylinder 3; and a limit block 32 slidably engaged in the inner groove 202 at the top of the vertical rod 31. A vertical rod 34 is slidably engaged at the inner end of the limiting groove 201. A collar 35 is fixedly connected to the lower end of the vertical rod 34 and is sleeved on the outer end of the vertical rod 34. A stop ring 33 with a diameter smaller than that of the transplanting cylinder 3 is fixedly connected to the bottom end of the vertical rod 34. A load-bearing block 36 is fixedly connected to the top end of the vertical rod 34. The sliding plate 12, the transplanting cylinder 3 and the stop ring 33 are all notched. The bottom end of the transplanting cylinder 3 is cone-shaped. The lower connecting strip 22 is fixedly connected between the connecting plates 21. The upper connecting strip 22 is slidably engaged in the groove between the connecting plates 21.

[0019] One of the connecting plates 21 has a synchronization controller installed on its outer wall, and the two cylinders 23 are electrically connected to an external power supply through the synchronization controller. The lower connecting strip 22 is fixed between the connecting plates 21, and the upper connecting strip 22 is slidably engaged in the groove of the connecting plate 21, providing a stable installation and sliding guide foundation for the lifting and lowering of the transplanting cylinder 3; The second vertical rod 34 is slidably engaged in the limiting groove 201. The collar 35 is sleeved on the outer end of the second vertical rod 34 to serve as a guide. The diameter of the abutment ring 33 is smaller than that of the transplanting cylinder 3 and its bottom end is in contact with the soil. It can limit the seedling to prevent displacement during transplanting. The weight block 36 provides gravity driving force for the second vertical rod 34 to move downward. The sliding plate 12, the transplanting tube 3, and the retaining ring 33 are notched to facilitate seedling placement, planting, and disengagement of components after transplanting; the bottom of the transplanting tube 3 is conical to reduce soil insertion resistance and achieve rapid and accurate insertion.

[0020] In use, based on the standardized adjustment of transplanting row spacing completed in Example 1, each transplanting cylinder 3 is precisely aligned with the sliding plate 12 via the limiting ring 13, ensuring that all transplanting components are evenly distributed along the preset row spacing. After placing qualified vegetable seedlings into the inner cavity of the transplanting cylinder 3, the cylinder 23 is activated, driving the upper connecting strip 22 to move downwards in the vertical direction. Through the transmission connection between the vertical rod 31 and the limiting block 32, the transplanting cylinder 3 moves downwards synchronously, and its conical bottom end is vertically inserted into the preset depth of the soil, completing the wrapping positioning of the seedling's outer side. At this time, the abutment ring 33 at the bottom of the vertical rod 34 fits against the top surface of the soil and presses against the outer side of the seedling, forming an axial limit to prevent the seedling from shifting or tipping over during transplanting. Subsequently, cylinder 23 drives connecting bar 22 to move upward in the reverse direction, and transplanting cylinder 3 is synchronously reset under the guidance of limiting ring 13. Seedlings are retained at the planting position under the limiting effect of abutment ring 33 and the adsorption effect of soil, realizing precise transplanting of seedlings and soil. Moreover, transplanting cylinder 3 and supporting components such as abutment ring 33 and vertical rod 34 will move synchronously with the sliding plate 12 when adjusting row spacing in the embodiment, ensuring the consistency and standardization of row spacing throughout the transplanting process.

[0021] 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.
