Description

Technical Field

[0001] The utility model relates to a seedling raising device, in particular to a crop seedling raising device, belonging to the technical field of crop seedling raising. Background Art

[0002] One of the traditional methods of raising seedlings for crops is to reserve a piece of land in a crop greenhouse for cultivating seedlings of various crops. This method affects the consistency of land care in the crop greenhouse. In addition, during the seedling raising process, the crop seedlings absorb nutrients from the soil. After the seedling raising is completed, when crops are planted in the reserved land, the crops in the nursery field grow relatively slowly due to the lack of soil nutrients, affecting the effect of reuse. Therefore, in the current process of raising seedlings for crops, seedlings are often raised in greenhouses. In order to save space, special seedling tray supports are often used for multi-layer seedling raising.

[0003] In the prior art, a crop seedling raising device disclosed in announcement number CN221283930U includes a seedling raising component and a spraying component, wherein the seedling raising component includes a connecting box, a bottom support, a cultivating box and a locking piece, the bottom support is connected and arranged on the side of the connecting box, the spraying component includes a driving piece, a movable box, a spraying head and a water pump, the driving piece is arranged on one side of the connecting box, the movable box is slidably arranged on the outside of the connecting box and is connected to the driving piece, and the spraying head is connected and arranged on the bottom of the movable box. By arranging the connecting box, the bottom support, the cultivating box and the locking piece, the cultivating box can be taken and placed in a horizontal pulling manner to avoid the seedlings from being collided. By arranging the driving piece, the movable box, the spraying head and the water pump, the driving piece is used to drive the movable box and the spraying head to adjust the height, thereby adapting to planting in various situations. The height requirement can be adjusted to greatly improve practicality. However, in actual use, although the existing seedling raising device can realize multi-layer seedling raising, the crop seedlings need to receive sufficient light to grow normally during the seedling raising process, and the existing device cannot move and unfold the layered cultivation boxes, which will cause the upper cultivation boxes to block the lower cultivation boxes to a certain extent, affecting the growth of the seedlings in the lower cultivation boxes. Secondly, the existing device is provided with a grille in the outer frame of the cultivation box, through which the seedlings can be cultivated separately, but it is not convenient to take out the crop seedlings after the seedling raising is completed. If a disposable seedling cup is placed in each seedling raising area, although it can be convenient for later removal, the seedling cup is not firmly placed in the cultivation box and is easy to tip over or fall, which is also not conducive to the smooth progress of seedling raising.

[0034] Embodiment 2

[0035] Improvements based on Example 1:

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, a locking groove 11 is provided on the inner side of the frame body of the seedling support frame 1, and the positions of the locking grooves 11 on the frame body of the seedling support frame 1 are symmetrically arranged. The frame bodies on both sides of the seedling plate positioning frame 2 are respectively locked in the locking grooves 11, so that the frame bodies on both sides of the seedling plate positioning frame 2 are respectively connected to the seedling support frame 1 at two points, thereby ensuring that the seedling plate positioning frame 2 can remain stably connected to the seedling support frame 1.

[0037] Furthermore, a limiting rod 12 is vertically connected to the positioning groove 11 opened on the body of the seedling support frame 1, and the rod body of the limiting rod 12 is placed in the limiting movable groove 21. When the frame bodies on both sides of the seedling plate positioning frame 2 are respectively placed in the positioning grooves 11, the limiting rod 12 is placed in the limiting movable grooves 21 to ensure that the seedling plate positioning frame 2 will not fall off from the positioning grooves 11.

[0038] like Figure 1 , Figures 3 to 9 As shown, the inner side surfaces of the frame bodies on both sides of the seedling raising plate positioning frame 2 are provided with seedling raising plate slots 22, and when the two side edges of the seedling raising plate 3 are placed in the seedling raising plate slots 22, the upper movable plate 31 of the seedling raising plate 3 and the lower support plate 32 are tightly together, and the installation position of the seedling raising plate 3 can be fixed through the opened seedling raising plate slots 22, and when the seedling raising plate 3 is installed on the seedling raising plate positioning frame 2, the upper movable plate 31 and the lower support plate 32 are in a tightly contact state, so that the inner bevel ring 34 can be placed in the outer bevel ring 36, so that the inner bevel ring 34 is in a clamping state on the cup body of the seedling cup 4.

[0039] Furthermore, the body of the seedling cup 4 is in the shape of an inclined surface, and the inner walls of the upper through hole 33 and the lower through hole 35 are in contact with the body of the seedling cup 4. When the seedling cup 4 is placed in the upper through hole 33, the body of the seedling cup 4 can be initially fixed through the inner wall of the upper through hole 33. When the upper movable plate 31 and the lower support plate 32 are in a close contact state, the inner inclined ring 34 and the lower through hole 35 also fix the body of the seedling cup 4, that is, the body of the seedling cup 4 can be fixed in multiple places.

[0040] Furthermore, the inner side surface of the outer bevel ring 36 is fixedly connected with a plurality of bevel blocks 37, and the connection positions of the bevel blocks 37 are evenly distributed on the inner side surface of the outer bevel ring 36. The bevel blocks 37 can be arranged so that the inner bevel ring 34 can be further contracted inward when it is clamped in the outer bevel ring 36, thereby further improving the fixing effect of the seedling cup 4.

[0041] Furthermore, a plurality of springs 38 are connected between the upper movable plate 31 and the lower support plate 32 of the seedling raising plate 3, and the springs 38 are respectively sleeved on the outer sides of the inner bevel ring 34 and the outer bevel ring 36. The upper movable plate 31 and the lower support plate 32 can be combined together through the connection of the springs 38, and due to the elastic force of the springs 38, a gap can be left between the upper movable plate 31 and the lower support plate 32 in the initial state, so that the inner bevel ring 34 and the outer bevel ring 36 are separated. When the device is used, since there is a gap between the upper movable plate 31 and the lower support plate 32 in the initial state, the cup body of the seedling cup 4 passes through the upper through hole 33 opened by the upper movable plate 31, and the cup body of the seedling cup 4 also passes through the lower through hole 35 opened by the lower support plate 32, and the inner bevel ring 34 is attached to the outer side of the cup body of the seedling cup 4. When the seedling plate 3 is placed in the positioning groove 11, the upper movable plate 3 The upper movable plate 31 and the lower support plate 32 need to be tightly attached together, so that the thickness of the upper movable plate 31 and the lower support plate 32 is the same as the slot height of the positioning slot 11, so that the two sides of the seedling raising plate 3 can be easily inserted into the positioning slot 11, and due to the action of the spring 38, the upper movable plate 31 and the lower support plate 32 can have an opening force, so that the upper movable plate 31 and the lower support plate 32 can be respectively pressed against the upper and lower groove inner walls of the positioning slot 11, that is, it can ensure that the seedling raising plate 3 is in a stable state. The installation position in the positioning groove 11 is firm, and when the upper movable plate 31 and the lower support plate 32 are tightly attached together, the inner bevel ring 34 can be clamped in the outer bevel ring 36, and the outer side wall of the inner bevel ring 34 is in contact with the bevel stop block 37. Through the action of the bevel stop block 37, the inner bevel ring 34 can be deformed to tilt inward, that is, the inner bevel ring 34 can be formed to be inwardly contracted, so that the inner bevel ring 34 can tighten and fix the cup body of the seedling cup 4 in a ring shape.

[0042] Furthermore, a rotating motor 5 is coaxially fixedly connected to the bottom end of the rotating rod 51, and the body of the rotating motor 5 is fixedly connected to the seedling support frame 1, and the rotating motor 5 is electrically connected to an external power supply, so that the rotating motor 5 can drive the rotating rod 51 to rotate, thereby driving the seedling plate positioning frame 2 to be retracted, extended, moved and adjusted.

[0043] Working principle: first, place the seedling cup 4 in the upper through hole 33 of the seedling plate 3, and the cup body of the seedling cup 4 can be initially fixed through the inner wall of the upper through hole 33, and the seedling soil and crop seeds are placed in the seedling cup 4, and then the two sides of the seedling plate 3 are inserted into the positioning grooves 11 opened on the inner side of the frame body of the seedling support frame 1, and the upper movable plate 31 of the seedling plate 3 is in a close contact with the lower support plate 32, and the inner bevel ring 34 and the lower through hole 35 also fix the cup body of the seedling cup 4, that is, the cup body of the seedling cup 4 can be fixed in multiple places, After the crop seeds germinate, the rotating motor 5 can be used to drive the rotating rod 51 to rotate, and the meshing action of the gear 52 and the rack 23 can drive the seedling plate positioning frame 2 to move relative to the seedling support frame 1, so that the two seedling plate positioning frames 2 on the upper and lower layers can move in opposite directions to ensure that the seedling plates 3 on the seedling plate positioning frame 2 can be exposed to more sunlight, and because the seedling plate positioning frame 2 can extend to both sides respectively, it can ensure that the center of the seedling raising device remains stable and the seedling raising device can be stably placed.
