Description

Technical Field

[0001] The invention relates to the technical field of seedling planting devices, and in particular to a planting device for chestnut seedlings which is convenient for transplanting. Background Art

[0002] Chestnut is an economic plant belonging to the genus Castanea of ​​the Fagaceae family. It is rich in nutrients such as starch, monosaccharides and disaccharides, carotene, thiamine, riboflavin, niacin, ascorbic acid, protein, fat, inorganic salts, etc. It can not only be eaten raw or cooked, but also processed into flavored foods such as canned chestnut chicken, chestnut soup, chocolate, milk replacer, chestnut candied fruit, and used as fillings for various pastries.

[0003] For example, the Chinese patent with announcement number CN108476794A discloses a sapling planting device that is easy to transplant, including a pot body, a nutrient soil layer, a wood block layer, a geotextile layer, a coal ash layer, a water hole, a ventilation hole, a plastic bag, a binding rope and a sapling. The bottom of the pot body is provided with a water hole, and a plastic bag is placed in the pot body. The plastic bag is provided with a nutrient soil layer, a wood block layer, a geotextile layer and a coal ash layer from top to bottom in sequence. The sapling is planted in the nutrient soil layer, and the upper end of the plastic bag is tied to the sapling by a binding rope.

[0004] However, the above scheme has the following shortcomings: in the above patent, the root system of the saplings will not be damaged by transplanting them together with the plastic bag. Although the survival rate of the saplings can be improved, the roots of the saplings just transplanted cannot quickly pass through the plastic bag and extend into the nearby soil. This results in the nutrients in the soil near the saplings being blocked by the plastic bag after transplanting, and the nutrients in the soil can only be absorbed by the roots of the saplings through the multiple air holes at the bottom of the plastic bag, causing the saplings just transplanted to be unable to quickly absorb nutrients for growth, resulting in slow growth. For this reason, we have introduced a chestnut variety seedling planting device that is easy to transplant. Summary of the invention

When the external force squeezes or pulls, the elastic expansion board 2 will return to its original state. The elastic expansion board 2 is pulled and contracted, so that the arc-shaped board 1 buried in the soil after transplanting the seedlings can be taken out upward. A reset support mechanism is provided in the elastic expansion board 2. The elastic expansion board 2 is supported by the reset support mechanism to prevent the elastic expansion board 2 from being squeezed and deformed by the soil. At the same time, the elastic expansion board 2 can be restored to its original shape after being pulled and contracted by the reset support mechanism.

[0025] A liquid storage chamber 10 is provided on both sides of the reset support mechanism. The liquid storage chamber 10 is provided in the elastic expansion plate 2. The liquid storage chamber 10 is used to store the nutrient solution. The liquid storage chamber 10 is connected to the external environment through the drainage hole 8. The drainage hole 8 is provided in the elastic expansion plate 2. The end of the liquid storage chamber 10 away from the drainage hole 8 is connected to the one-way valve 11. The one-way valve 11 is fixedly installed in the elastic expansion plate 2. The one-way valve 11 is away from the end of the liquid storage chamber 10 and extends into the external environment. The liquid is injected into the liquid storage chamber 10 through the one-way valve 11. Nutrient solution, a blocking and pulling mechanism is provided in the drainage hole 8, and the end of the blocking and pulling mechanism away from the drainage hole 8 passes through the elastic telescopic plate 2 and the arc plate 1 and extends into the external environment. By pulling the blocking and pulling mechanism, the blocking and pulling mechanism cancels the blockage of the drainage hole 8, and at the same time, the elastic telescopic plate 2 is pulled and contracted. After the elastic telescopic plate 2 is pulled and contracted, the nutrient solution in the liquid storage chamber 10 will be squeezed into the soil of the external environment, and the growth rate of the chestnut seedlings after transplanting will be increased by the nutrient solution. Embodiment 2:

[0026] On the basis of Example 1, in order to enable the chestnut seedlings to grow rapidly after transplantation, the limiting mechanism includes a T-shaped clamping plate 6, which is slidably connected to the limiting cavity 15. The limiting cavity 15 is opened in one end of the arc plate 1, and a clamping groove 14 is opened in the end of the arc plate 1 away from the limiting cavity 15. The T-shaped clamping plate 6 is clamped in the clamping groove 14 at one end of another group of arc plates 1, so that the two groups of arc plates 1 are installed together. The end of the T-shaped clamping plate 6 close to the limiting cavity 15 is fixedly connected to the first traction rope 9, and the end of the first traction rope 9 away from the T-shaped clamping plate 6 passes through the arc plate 1 and extends upward into the external environment, and is fixedly connected to the first pull plate 17. The first spring is sleeved on the outside of the first traction rope 9. 16, one end of the first spring 16 is fixedly connected to the T-shaped clamping plate 6, and the other end is fixedly connected to the limiting cavity 15. By pulling the first pull plate 17 upward in sequence, the first traction rope 9 connected thereto is driven to move, and the first traction rope 9 moves to drive the T-shaped clamping plate 6 to be received into the limiting cavity 15. At this time, the first spring 16 is compressed. When the T-shaped clamping plates 6 in the four groups of arc plates 1 are all received into the limiting cavity 15, the four groups of arc plates 1 are spliced ​​together to form a complete circle, and the pulling of the first pull plate 17 is released in sequence. At this time, under the elastic force of the first spring 16, the T-shaped clamping plate 6 will be clamped into the clamping groove 14, so that the four groups of arc plates 1 are installed together, and the chestnut seedlings can be planted at this time;

[0027] The reset support mechanism includes a telescopic support tube 4, which is composed of a plurality of groups of support rings that are sleeved with each other. Both ends of the telescopic support tube 4 are fixedly connected to the connecting cavity 12, and the connecting cavity 12 is opened in the elastic telescopic plate 2. A second spring 5 is sleeved on the outside of the telescopic support tube 4, and both ends of the second spring 5 are fixedly connected to the connecting cavity 12. The two groups of blocking plates 13 simultaneously pull and contract the elastic telescopic plate 2, so that the second spring 5 is compressed. At the same time, the telescopic support tube 4 located in the connecting cavity 12 will shrink and fold together. When the elastic telescopic plate 2 is completely contracted together, the group of arc plates 1 can be taken out of the soil. One end of the telescopic support tube 4 is fixedly connected to an L-shaped support plate 3, and the L-shaped support plate 3 extends into the external environment away from one end of the telescopic support tube 4, and is fixedly connected to the arc plate 1. Through the arrangement of the L-shaped support plate 3, the telescopic support tube 4 can support the elastic telescopic plate 2 and the soil on the elastic telescopic plate 2;

[0028] The blocking and pulling mechanism includes a blocking plate 13, which is slidably connected to the guide groove 7. The guide groove 7 is arranged in the elastic telescopic plate 2, and the guide groove 7 is connected to the drainage hole 8. The blocking plate 13 is fixedly connected to the second traction rope 19 at one end close to the guide groove 7. The second traction rope 19 extends upward into the external environment through the elastic telescopic plate 2 and the arc plate 1 at one end away from the blocking plate 13, and is fixedly connected to the second pull plate 18. A third spring 20 is sleeved on the outside of the second traction rope 19. One end of the third spring 20 is fixedly connected to the blocking plate 13, and the other end is fixedly connected to the guide groove 7. When the blocking plate 13 completely enters the guide groove 7 and cannot move further, at this time, as the second traction rope 19 continues to pull the blocking plate 13, the blocking plate 13 will drive the elastic telescopic plate 2 to contract. During the contraction of the elastic telescopic plate 2, the nutrient solution in the liquid storage chamber 10 will be squeezed into the soil of the external environment from the drainage hole 8, and the growth rate of the chestnut seedlings after transplanting will be improved by the nutrient solution.

[0029] Working principle: when in use, the first pulling plate 17 is pulled upward in sequence to drive the first traction rope 9 connected thereto to move, and the movement of the first traction rope 9 drives the T-shaped clamping plate 6 to be received into the limiting cavity 15. At this time, the first spring 16 is compressed. When the T-shaped clamping plates 6 in the four groups of arc-shaped plates 1 are all received into the limiting cavity 15, the four groups of arc-shaped plates 1 are spliced ​​together to form a complete circle, and the pulling of the first pulling plate 17 is released in sequence. At this time, under the elastic force of the first spring 16, the T-shaped clamping plate 6 will be clamped into the clamping groove 14, so that the four groups of arc-shaped plates 1 are installed together, and the chestnut seedlings can be planted at this time;

[0030] When it is necessary to transplant the grown chestnut seedlings, several groups of arc plates 1 and chestnut seedlings are placed into the transplanting pit together. After the placement is completed, the chestnut seedlings can be buried. When the burying is completed, the first pull plate 17 and the second pull plate 18 on the two groups of arc plates 1 are pulled upward. The first pull plate 17 moves upward to drive the corresponding T-shaped clamping plate 6 to disengage from the clamping groove 14, and the second pull plate 18 moves upward to drive the two groups of second traction ropes 19 connected thereto to move. The movement of the second traction rope 19 drives the blocking plate 13 to move into the guide groove 7. At this time, the third spring 20 is compressed. When the blocking plate 13 completely enters the guide groove 7 and cannot move further, as the second traction rope 19 continues to pull the blocking plate 13, the blocking plate 13 will drive the elastic telescopic plate 2 to shrink. During the shrinkage of the elastic telescopic plate 2, the nutrient solution in the liquid storage chamber 10 will be squeezed into the soil of the external environment from the drainage hole 8;

[0031] The two groups of blocking plates 13 simultaneously pull and contract the elastic telescopic plate 2, so that the second spring 5 is compressed, and at the same time the telescopic support tube 4 located in the connecting cavity 12 will shrink and fold together. When the elastic telescopic plate 2 is completely contracted together, the group of arc plates 1 can be taken out from the soil at this time, and the remaining arc plates 1 can be taken out in turn according to the above method. After taking them out, several groups of arc plates 1 are assembled together again, and nutrient solution is injected into the liquid storage cavity 10 through the one-way valve 11.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
