Description

Technical Field

[0001] The utility model relates to the technical field of seedling supports, in particular to a device for supporting and fixing seedlings. Background Art

[0002] Seedlings usually refer to seedlings that have just grown out of the ground, specifically plants that have just begun to grow. In gardening, agriculture and forestry, seedlings refer to small saplings or shrubs that are artificially cultivated for planting. By planting seedlings, plant growth can be accelerated to achieve purposes such as garden beautification and forest renewal. The cultivation of seedlings requires certain techniques and conditions, such as suitable soil, water, sunlight, etc.

[0003] When transplanting seedlings to the foundation pit and filling the soil, the soil is generally not compacted during the filling process, and the filling soil is kept loose because the root system of the seedlings has high requirements for the aeration and drainage of the soil. However, since the root system of the seedlings has not yet taken root deeply after transplantation, it is easy for the seedlings to tilt, collapse or even die. For this reason, a supporting and fixing device is needed to protect the seedlings. The current seedling supporting and fixing device is mainly composed of a round sleeve and a support frame. The principle is that the round sleeve is put on the seedling, one end of the support frame is inserted into the soil, and the other end is connected to the round sleeve to play a supporting role. However, the current device has a single structure and cannot be adjusted according to the height and thickness of the seedling trunk. It is difficult to apply to seedlings of different sizes and has poor applicability. Therefore, the supporting effect is poor, and the seedlings are prone to tilt, affecting their normal growth.

The front and rear sides of the circular plate 3 are vertically equidistantly provided with multiple card slots 44 that are connected to the right side thereof. The card slots 44 on the front and rear sides are arranged in a one-to-one correspondence. The upper end of the left side of the support frame 2 is provided with an extrusion rod 41 that extends to its right side and passes through the circular plate 3. The extrusion rod 41 is fixedly sleeved with a card plate 43 whose two ends extend to the inside of the two uppermost card slots 44.

During this process, the left end of the clamping rod 124 moves to the right to leave space for the placement slot 9, and the spring 122 is stretched. At this time, after the placement block 11 is placed in the placement slot 9, the limit block 123 is released. Driven by the elastic force, the limit block 123 and the clamping rod 124 return to their original positions, and the left end of the clamping rod 124 enters the rod groove 121 on the placement block 11, completing the limitation of the placement block 11 and preventing the placement block 11 from leaving the placement slot 9. The clamping rod 124 is pulled so that its left end leaves the rod groove 121 on the placement block 11, and the limitation of the placement block 11 can be released.

[0033] Preferably, as another embodiment of the utility model, a rocker 13 is provided at the left end of one of the bidirectional screw rods 7, a shell 14 is provided on the left side of the circular plate 3, the synchronous belt 81 and the synchronous wheel 82 are both located inside the shell 14, and the right end of the bidirectional screw rod 7 passes through the left side of the shell 14.

[0034] In this embodiment, the shell 14 can protect the wrapped synchronous belt 81 and synchronous wheel 82 to prevent them from being hit by external objects or impurities from entering the two, thereby isolating them from the outside world. The rocker 13 can be easily held by the user and shaken to quickly drive the bidirectional screw 7 connected thereto to rotate quickly.

[0038] In this embodiment, the connecting rod 17 can connect the rubber block 18 with the arc plate 10, and when fixing the trunk of the seedling, the rubber block 18 is in contact with the trunk. The rubber block 18 is made of rubber material, and the rubber has a certain softness, that is, elasticity, which can buffer the contacting trunk surface and reduce the extrusion on the trunk surface. At the same time, it can scratch the bark surface.

[0039] Working principle: Place the concave plate 1 on both sides of the seedlings, that is, the seedlings are located on the inner side of the concave plate 1.

At this time, hold the rocker 13 to drive one of the two-way screw rods 7 to rotate. In this process, the transmission effect of the synchronous belt 81 and the synchronous wheel 82 is used to drive a two-way screw rod 7 to rotate synchronously. In this process, the slider 6 and the two-way screw rod 7 are transmitted, so that the sliders 6 on both sides are close to each other, and drive the arc plates 10 on both sides to be close to each other.
