Description

Technical Field

[0001] The invention relates to the technical field of market gardens, and in particular to an intelligent seedling raising box and a seedling raising method for municipal gardens. Background Art

[0002] Municipal gardens usually refer to parks. As places for leisure and relaxation, parks have a large number of trees planted inside. As municipal facilities, during the construction of municipal gardens, it is necessary to carry out seedling cultivation operations on green plants.

[0003] For example, a Chinese utility model provides a "seedling raising box for garden planting", and its announcement number is: CN211048090U. The application includes a box body, and a sliding groove is provided through the side of the box body in the length direction. A sliding box with a plurality of air holes on the surface is slidably installed inside the sliding groove. A limit plate for limiting the position of the sliding box is hinged on the upper part of the open end of the sliding groove. A locking assembly is installed on the outside of the box body, and a controller for controlling the operation of the device is installed on the side wall of the box body. The beneficial effect is that the device can provide light according to the needs of seedling development to ensure the cultivation effect of the seedlings; The sliding box is inserted into the sliding groove, and the sliding box and the sliding groove are sealed by a limit plate to ensure the insect-proof ability of the cultivation chamber and prevent pests from entering and affecting the seedlings; the height of the seedling roots can be adjusted according to the growth stage of the seedlings, thereby ensuring that the seedlings can have sufficient contact with the air, preventing excessive contact area with water, and avoiding inhibition of aerobic respiration of the seedlings.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0031] In view of the problems existing in the prior art, the embodiments of the present invention provide an intelligent nursery box for municipal gardens, such as Figure 1 and Figure 2As shown, the intelligent nursery box for municipal gardens includes a nursery box body 1, a connecting box 2 is fixedly connected to the outer wall of the nursery box body 1, and a connecting hole 7 is provided on the side walls of the connecting box 2 and the nursery box body 1. The connecting hole 7 is used to connect the inner cavity of the connecting box 2 with the inner cavity of the nursery box body 1. The connecting hole 7 is arranged close to the bottom of the nursery box body 1 and the connecting box 2, and the cavity of the connecting hole 7 is arranged in a horizontal direction. The purpose of this is to ensure that the height of the nutrient solution in the connecting box 2 and the nursery box body 1 can always be kept consistent. A connecting tube 3 is fixedly connected on the connecting box 2 and the seedling box body 1. The connecting tube 3 is used for connecting the nutrient solution source and the inner cavity of the seedling box body 1. A first electrode contact assembly 4 and a second electrode contact assembly 5 are arranged in the connecting box 2. During operation, when the nutrient solution in the seedling box body 1 is lower than a first preset threshold value (it can be understood that the plants cannot grow normally below this liquid level), the contact between the first electrode contact assembly 4 and the second electrode contact assembly 5 will control the start of the nutrient solution source to transport the nutrient solution into the seedling box body 1.

[0032] In one embodiment, if Figure 3 As shown, the first electrode contact assembly 4 includes a floating plate 41 movably arranged in the connection box 2, a first telescopic assembly 42 is fixedly connected to the lower end surface of the floating plate 41, the lower end of the first telescopic assembly 42 is fixedly connected to the inner bottom wall of the connection box 2, a vertical rod 43 is connected to the upper end surface of the floating plate 41, the upper end of the vertical rod 43 is fixedly connected to the first electrode contact 44, the second electrode contact assembly 5 includes a second electrode contact 51 which is mutually opposed to the first electrode contact 44, a moving hole 52 which passes through the lower part is opened in the middle part of the second electrode contact 51, the vertical rod 43 is movably inserted in the moving hole 52, a fixing tube 53 is fixedly connected to the upper end surface of the second electrode contact 51, the upper end of the fixing tube 53 is fixedly connected to the lower end surface of the connecting tube 3, and the connecting tube 3 is covered outside the first electrode contact 44.

[0033] During operation, as the liquid level of the nutrient solution decreases, the float plate 41 moves downward. The downward movement of the float plate 41 will carry the first electrode contact 44 downward through the vertical rod 43. When the first electrode contact 44 contacts the second electrode contact 51, the nutrient solution source is started (it can be understood that the pump body of the nutrient solution source is started), and the nutrient solution can be transported to the seedling box body 1 through the connecting tube 3.

[0034] In one embodiment, if Figure 3As shown, the first telescopic assembly 42 includes a first telescopic rod 421, a first telescopic tube 422 and a first telescopic spring 423. The first telescopic rod 421 is movably inserted in the first telescopic tube 422. The first telescopic spring 423 is wound and arranged outside the first telescopic rod 421. The two ends of the first telescopic spring 423 are respectively fixedly connected to the side wall of the first telescopic rod 421 and the outer side wall of the first telescopic tube 422. The first telescopic rod 421 is connected to the floating board 41, and the first telescopic tube 422 is connected to the connection box 2. The setting of the first telescopic assembly 42 can play a guiding and supporting role for the movement of the floating board 41, so that the floating board 41 can only move in the vertical direction. At the same time, when the liquid level of the nutrient solution drops, it can pull the floating board 41 to move downward.

[0035] In one embodiment, if Figure 2 and Figure 3 As shown, the intelligent seedling box for municipal gardens also includes a blocking mechanism 6, which includes a blocking plate 61, which is movably inserted in a cylinder hole 63, and the cylinder hole 63 is opened on the top plate of the connecting pipe 3 and the top plate of the connecting box 2. The upper end of the blocking plate 61 is fixedly connected to a cylinder arm 62, and the cylinder arm 62 is movably arranged in the cylinder hole 63. The upper end of the cylinder arm 62 is fixedly connected to a connecting end 64, and the connecting end 64 is arranged on a driving cylinder 65, and the driving cylinder 65 is fixedly arranged on a fixing cylinder 66, and the fixing cylinder 66 is fixedly arranged on the outer top wall of the connecting box 2.

[0036] The blocking mechanism 6 in this embodiment is used to intermittently block the connecting tube 3. Specifically, when the liquid level in the seedling box body 1 is lower than the first preset threshold, the blocking mechanism 6 will be activated and adjusted to open the inner cavity of the connecting tube 3, so that the nutrient solution can enter the seedling box body 1. When the nutrient solution in the seedling box body 1 is higher than the first preset threshold, the blocking mechanism 6 will be adjusted to close the inner cavity of the connecting tube 3, thereby stopping the injection of nutrient solution into the seedling box body 1. Specifically, when the first electrode contact 44 and the second electrode contact 51 are in contact, the driving cylinder 65 is activated. At this time, the driving cylinder 65 works to move the blocking plate 61 upward through the cylinder arm 62, the inner cavity of the connecting tube 3 is opened, and the nutrient solution can be injected into the seedling box body 1.

[0037] In the process of injecting nutrient solution into the seedling box body 1, in order to avoid the fluctuation of the liquid, resulting in the movement of the floating plate 41, thereby causing the first electrode contact sheet 44 and the second electrode contact sheet 51 to separate, in one embodiment, as shown in FIG. Figure 3 and Figure 4As shown, the intelligent nursery box for municipal gardens also includes a locking mechanism 8, and a plurality of the locking mechanisms 8 are provided. The plurality of the locking mechanisms 8 are distributed around the vertical center line of the floating plate 41. The locking mechanism 8 includes a first locking groove 81, a locking rod 82 and a second locking groove 83. The first locking groove 81 is provided on the floating plate 41, and the second locking groove 83 is provided on the connecting box 2. The locking rod 82 is movably inserted into the first locking groove 81 and the second locking groove 83. A U-shaped through hole 85 is provided on the connecting box 2, and one end of the U-shaped through hole 85 is interconnected with the second locking groove 83, and the other end of the U-shaped through hole 85 is interconnected with the inner cavity of the connecting box 2.

[0038] In one embodiment, if Figure 4 As shown, the locking mechanism 8 also includes a second telescopic component 84, which includes a second telescopic rod 841, a second telescopic tube 842 and a second telescopic spring 843. The second telescopic rod 841 is movably inserted in the second telescopic tube 842, and the second telescopic spring 843 is wound outside the second telescopic rod 841. One end of the second telescopic spring 843 is fixedly connected to the side wall of the second telescopic rod 841, and the other end of the second telescopic spring 843 is fixedly connected to the outer side wall of the second telescopic tube 842. The second telescopic tube 842 is interconnected with the side wall of the first locking groove 81, and the second telescopic rod 841 is interconnected with the locking rod 82.

[0039] The setting of the locking mechanism 8 in this embodiment can prevent the floating plate 41 from moving up and down with the fluctuation of the liquid level during the process of injecting nutrient solution into the seedling box body 1 (it should be understood that it is mainly the adjustment process when the liquid level is lower than the first preset threshold value), thereby avoiding the separation of the first electrode contact piece 44 and the second electrode contact piece 51 during the process. Specifically, when the liquid level is lower than the first preset threshold value, the locking rod 82 will enter the second locking groove 83 under the push of the second telescopic component 84. At this time, the locking rod 82 is stored in the first locking groove 81 and the second locking groove 83 at the same time, and the floating plate 41 is locked in the connection box 2. In this state, the first electrode contact piece 44 and the second electrode contact piece 51 are always in contact. As the liquid level in the seedling box body 1 increases, the nutrient solution will enter the second locking groove 83 through the U-shaped through hole 85 and push the locking rod 82 to move to the left. When the locking rod 82 moves to the outside of the second locking groove 83, the floating plate 41 is unlocked. At this time, under the push of the liquid, the floating plate 41 can move upward.

[0040] In one embodiment, if Figure 5As shown, the intelligent nursery box for municipal gardens also includes a connecting mechanism 9, which is used to connect the vertical rod 43 and the floating board 41, and enables the vertical rod 43 and the floating board 41 to move relative to each other. The connecting mechanism 9 includes a connecting column 91 and a connecting through hole 92. The connecting column 91 is movably inserted in the connecting through hole 92, and the connecting column 91 is fixed on the lower end of the vertical rod 43. The connecting through hole 92 is opened on the floating board 41. The lower end of the connecting column 91 is fixedly connected with a third telescopic component 93, and the lower end of the third telescopic component 93 is fixedly connected to the bottom wall of the connecting through hole 92.

[0041] The setting of the connecting mechanism 9 in this embodiment can make the contact time of the first electrode contact piece 44 and the second electrode contact piece 51 longer, and at the same time, it can avoid the rigid connection between the first electrode contact piece 44 and the second electrode contact piece 51, so as to protect the first electrode contact piece 44 and the second electrode contact piece 51. During operation, after the first electrode contact piece 44 and the second electrode contact piece 51 come into contact, the liquid level continues to decrease, which will cause the float plate 41 to continue to move downward. At this time, due to the setting of the combined structure of the connecting column 91, the connecting through hole 92 and the third telescopic component 93, the float plate 41 can move downward relative to the vertical rod 43.

[0042] In one embodiment, if Figure 5 As shown, the third telescopic assembly 93 includes a third telescopic rod 931, a third telescopic cylinder 932 and a third telescopic spring 933. The third telescopic rod 931 is movably inserted in the third telescopic cylinder 932, and the third telescopic spring 933 is wound outside the third telescopic rod 931. One end of the third telescopic spring 933 is fixedly connected to the side wall of the third telescopic rod 931, and the other end of the third telescopic spring 933 is fixedly connected to the outer side wall of the third telescopic cylinder 932. The third telescopic cylinder 932 is interconnected with the connecting through hole 92, and the third telescopic rod 931 is interconnected with the connecting column 91. The setting of the third telescopic assembly 93 can not only play a guiding and supporting role for the movement of the connecting column 91, so that the connecting column 91 or the floating board 41 can only move in the vertical direction, but also provide a reset force for the reset movement of the connecting column 91 or the floating board 41.

[0043] In one embodiment, if Figure 6 and Figure 7As shown, the municipal garden intelligent nursery box also includes a third electrode contact assembly 10, and the third electrode contact assembly 10 is used to control the nutrient solution source to be closed when the nutrient solution height in the nursery box body 1 reaches a second preset threshold value (it can be understood that when the nutrient solution level is higher than this level, the plant wastes nutrient solution, and when it is between the first preset threshold value and the second preset threshold value, the plant can maintain an excellent growth state and avoid waste of nutrient solution). The third electrode contact assembly 10 includes a third electrode contact 101, and the third electrode contact 101 is arranged directly above the first electrode contact 44, and the first electrode contact 44 is movably inserted in the movable groove 102, and the movable groove 102 is provided on the connecting tube 3. A reset spring 103 is fixedly connected to the top wall of the movable groove 102, and the lower end of the reset spring 103 is fixedly connected to the upper end surface of the third electrode contact 101, and a buffer pad 104 is movably sleeved outside the third electrode contact 101, and the buffer pad 104 is fixedly arranged on the outer side wall of the connecting tube 3.

[0044] During operation, as the liquid level of the nutrient solution in the seedling box body 1 increases, the float plate 41 will be pushed upward. The upward movement of the float plate 41 will carry the first electrode contact 44 upward through the vertical rod 43. When the first electrode contact 44 contacts the third electrode contact 101, the source of the nutrient solution is closed. At the same time, the driving direction of the driving cylinder 65 is changed, causing the sealing plate 61 to move downward, completing the sealing of the connecting pipe 3. At this time, the injection of nutrient solution into the seedling box body 1 will be stopped.

[0045] In view of the problems existing in the prior art, the embodiments of the present invention also provide an intelligent seedling raising method for municipal gardens, such as Figure 8 As shown, the municipal garden intelligent seedling raising box is used to raise seedlings, including the following steps:

[0046] S1: When the height of the nutrient solution in the seedling box body 1 is lower than the first preset threshold, the first electrode contact piece 44 and the second electrode contact piece 51 are in contact, and the nutrient solution source is activated to transport the nutrient solution into the connecting tube 3;

[0047] S2: When the nutrient solution source is activated, the driving cylinder 65 is also activated to drive the blocking plate 61 to move upward to open the connecting pipe 3 so that the nutrient solution is input into the seedling box body 1;

[0048] S3: As the height of the nutrient solution in the seedling box body 1 increases, the locking mechanism 8 is driven, and the floating plate 41 is unlocked, so that the floating plate 41 can move upward;

[0049] S4: When the height of the nutrient solution in the seedling box body 1 reaches the second preset threshold, the first electrode contact 44 and the third electrode contact 101 are in contact, the source of the nutrient solution is closed, and the driving cylinder 65 adjusts the driving direction relative to S2 to make the blocking plate 61 move downward to block the connecting pipe 3.

[0050] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
