Technical Field

[0001] This utility model relates to the field of whole-root transplanting technology for plant seedlings, specifically a whole-root transplanting device for plant seedlings. Background Technology

[0002] Plant seedlings refer to seedlings used for planting. They are the starting point of agricultural production and play a key role in ensuring high yield, high quality, and high efficiency of crops. Seedlings are also divided into different types according to different classification standards. High-quality seedlings can increase crop yield, enhance crop resistance to adverse conditions, meet market demands, and improve product competitiveness. Therefore, plant seedlings are a very important field.

[0003] Plant transplantation refers to digging up plants from their planting area and transplanting them to another plot of land for continued cultivation. Plant transplantation can increase the nutrient area, improve ventilation and light conditions, promote the growth of lateral and fibrous roots, and improve the quality of growth. Nowadays, most of the digging is done using agricultural tools such as shovels to achieve the purpose of whole-root transplantation. However, during the transplantation process, some plants have deep roots and some have shallow roots. If the length of the stem is difficult to adjust, it will bring additional burden to the operator. Utility Model Content

[0004] The purpose of this invention is to provide a plant seedling whole-root transplanting device to solve the problem mentioned in the background art that the difficulty in adjusting the length of the stem during transplanting can easily bring additional burden to the operator.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A whole-root transplanting device for plant seedlings includes a seedling tube, an adjusting sleeve, and an adjusting rod. The bottom of the adjusting sleeve is connected to the top of the seedling tube, and the adjusting rod is inserted and fixed inside the adjusting sleeve. The adjusting rod has multiple adjusting holes, which pass through the adjusting rod and are perpendicular to the central axis of the adjusting rod. Two pre-reserved holes are opened on the upper side of both sides of the adjusting sleeve, which are interconnected. A locking pin is inserted into the pre-reserved hole (16), which passes through the pre-reserved hole and the adjusting hole on the adjusting rod and is fixed by a fixing device. A handle is fixed to the top of the adjusting rod.

[0007] Furthermore, the handle is cylindrical, with a first adhesive layer on the bottom outer surface of the handle, a sponge pad on the outer surface of the first adhesive layer, a second adhesive layer on the top outer surface of the handle, and a rubber pad fixed on the outer surface of the second adhesive layer.

[0008] Preferably, the outer surface of the rubber pad is fixed with anti-slip protrusions.

[0009] More preferably, the anti-slip protrusion is integrally formed with the rubber pad.

[0010] Preferably, the whole formed by the first adhesive layer and the sponge pad is symmetrical about the central axis of the handle to the whole formed by the second adhesive layer and the rubber pad.

[0011] Furthermore, a third adhesive layer is fixed at the bottom of the adjusting sleeve, and a protective pad is bonded to the top of the third adhesive layer.

[0012] Furthermore, a reinforcing plate is provided on the lower outer side of the adjusting sleeve, and the bottom of the reinforcing plate is fixed to the top of the seedling tube.

[0013] Preferably, the plurality of reinforcing plates are triangular in shape and are distributed in a ring about the center of the adjusting sleeve.

[0014] Preferably, the outer sides of the locking pin are fixed with external threads, the fixing device is a locking nut, and a threaded connection is formed between the locking pin and the locking nut.

[0015] Furthermore, cutting plates are fixed on both sides of the bottom of the seedling tube, the cutting plates are symmetrically distributed about the central axis of the seedling tube, and spiral blades are evenly distributed on the outside of the seedling tube.

[0016] Compared with existing technologies, the beneficial effects of this utility model are: the whole-root transplanting device for plant seedlings not only improves the stem adjustment capability, but also enhances the operability and overall durability of the device. Specifically:

[0017] (1) By cooperating with the multiple adjustment holes on the adjustment rod and the reserved holes, locking pins, and locking nuts on the upper side of the adjustment sleeve, the adjustment rod can be inserted and fixed inside the adjustment sleeve. When it is necessary to adjust the combined height of the adjustment sleeve and the adjustment rod, the adjustment rod is allowed to move inside the adjustment sleeve. After reaching the appropriate height, the appropriate adjustment hole is aligned with the reserved hole. The locking pin is inserted into the reserved hole and the adjustment hole, and then the locking nuts are used to lock the locking pin at both ends. Furthermore, by setting a third adhesive layer and a protective pad at the bottom of the adjustment sleeve, when the adjustment rod touches the bottom of the adjustment sleeve, the protective pad can form a bottom buffer protection, thus improving the rod adjustment capability of the transplanting device and the durability of the overall device.

[0018] (2) By fixing the handle to the top of the adjusting rod, and sequentially setting the first rubber layer and sponge pad on the bottom outer surface of the handle, the fingertips can contact the sponge pad when the hand grips the handle, thus improving comfort. At the same time, a second rubber layer and rubber pad are sequentially set on the top outer surface of the handle, and anti-slip protrusions are evenly set on the outside of the rubber pad. Therefore, when the hand exerts force, it contacts the outer surface of the rubber pad, thereby improving the overall anti-slip effect and improving the comfort of hand operation.

[0019] (3) By installing and fixing the reinforcing plate on the lower part of the outside of the adjusting sleeve, the bottom of the reinforcing plate is fixed to the top of the seedling tube. At the same time, cutting plates are set on both sides of the bottom of the seedling tube, and spiral blades are evenly distributed on the outside of the seedling tube. Therefore, when in contact with the soil, the cutting plates can be used to penetrate into the surrounding soil first, while the spiral blades facilitate the subsequent entry of the seedling tube into the soil. This improves the operability of the whole root transplanting device for plant seedlings during the working process. Attached Figure Description
