Description

Technical Field

[0001] The present invention belongs to the technical field of seedling cultivation, and specifically relates to a straw-degrading nutrient seedling tray and a seedling cultivation method. Background Art

[0002] When cultivating seedlings, sometimes a seedling tray is needed. In the prior art, most seedling trays are made of plastic materials. For plastic materials, they cannot be effectively degraded in nature. When a user transplants seedlings, they need to take out the seedlings from the seedling tray. After planting the seedlings, they also need to recycle the seedling tray to prevent it from affecting the growth of seedlings in the field.

[0003] Currently, in China, some have also emerged to make seedling trays by hot-pressing shredded crop straws. The crop straws mainly include one or several of corn straws, rice straws, rice bran, thatch, bamboo powder, and wood powder. The main patents are CN1125502, CN1194773, CN1268283, and CN1557128, etc. When hot-pressing and forming, adhesives must be used. The adhesives used for flowerpots are mainly urea-formaldehyde resins, and the main adhesives used for seedling containers are polyacrylamide and oxidized starch, etc. With the development of modern agriculture, container seedling cultivation is being more and more widely adopted, and the seedling cultivation methods of vegetables, flowers, and seedlings at home and abroad are changing from traditional open-field seedling cultivation to container cultivation.

[0004] However, for the method of using crop straws to make seedling trays in the prior art, there are still certain inconveniences in its implementation. For example, when it is used, it is not convenient for users to transplant and plant seedlings. Therefore, this application proposes a straw-degrading nutrient seedling tray and a seedling cultivation method. Summary of the Invention

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0037] Given by Figures 1-9 the present invention discloses a straw-degrading nutrient seedling tray, which includes a tray part 1, a bottom lining plate 3, a transverse separating member, and a vertical separating member.

[0038] A number of tray units 2 arranged in a rectangle are provided on the tray part 1. The tray units 2 have transverse gaps and vertical gaps, and the tray units 2 are trapezoidal structures with a larger upper part and a smaller lower part. The tray part 1 is made of straw material. During the process of cultivating seedlings, the tray part 1 will also slowly decompose, thereby reducing the adhesion between each tray unit 2. That is, with a relatively small force, the purpose of separating the tray units 2 can be achieved.

[0039] By using the tray part 1 made of straw material, not only can it provide nutrients for the seedlings through the decomposition of the straw during the seedling cultivation, but also when transplanting the seedlings, the tray part 1 can be directly transplanted, avoiding the possible impact on the cultivation and transplantation of the seedlings caused by the use of plastics.

[0040] The tray part 1 is placed on the bottom lining plate 3. A slider 4 is fixedly connected to the side surface of the bottom lining plate 3. Both the transverse separating member and the vertical separating member are located above the bottom lining plate 3. The transverse separating member is located in the transverse gap, and the vertical separating member is located in the vertical gap. The transverse separating member is located above the vertical separating member.

[0041] By using the transverse separating member and the vertical separating member, when it is necessary to transplant the seedlings, the tray part 1 can be divided into individual tray units 2 to facilitate the transplantation of the seedlings. The use of the bottom lining plate 3 can also support the tray part 1 to facilitate the movement of the tray part 1.

[0042] The transverse separating member includes a first rotating rod 5 and a cross bar 8. The cross bar 8 passes through the transverse gap, and there are multiple cross bars 8. The first rotating rod 5 can rotate, and when the first rotating rod 5 rotates, the cross bars 8 can move in sequence to divide the tray part 1 into a transverse strip structure.

[0043] The vertical separating member includes a second rotating rod 9 and a vertical rod 11. The second rotating rod 9 can rotate, and when the second rotating rod 9 rotates, the vertical rod 11 can move in sequence to divide the transverse strip structure into individual tray units 2. The sequentially moving vertical rod 11 can facilitate the division of the strip structure of the tray part 1.

[0044] When implementing this device, soil is loaded into the tray unit 2, and then seeds are planted in the tray unit 2 to cultivate the seeds. When the seeds are cultivated into seedlings and the user transplants the seedlings, the horizontal separating member first divides the tray portion 1 into a horizontal strip structure, and then the vertical separating member divides the strip structure into individual tray units 2, thus facilitating the user to transplant the seedlings.

[0045] A first fixing block 7 is sleeved outside the first rotating rod 5. The number and positions of the first fixing blocks 7 correspond to the horizontal gaps. An annular groove 14 is provided inside the first fixing block 7. A dial block 15 is fixedly connected to the outside of the first rotating rod 5. A pushing block 16 is provided inside the first fixing block 7. The pushing block 16 is rotatably arranged inside the first fixing block 7. The dial block 15 can contact the pushing block 16 so that when the first rotating rod 5 rotates, the pushing block 16 can be pushed to rotate. An end block 17 is inserted at the lower end of the first fixing block 7, and the first fixing block 7 and the end portion 17 will not separate. The end block 17 is fixedly connected to the cross bar 8, and when the pushing block 16 is pushed, the end block 17 can drive the cross bar 8 to move.

[0046] The cross bar 8 is located at the top position of the horizontal gap. When the cross bar 8 moves, due to the easy separation characteristic of the tray portion 1 made of straw material, the cross bar 8 can divide the tray unit 1.

[0047] Each first fixing block 7 has a dial block 15 inside. The multiple dial blocks 15 are arranged in sequence on the circumferential surface of the first rotating rod 5, and the horizontal surface of the dial block 15 is an inclined surface so that when the dial block 15 rotates, the dial block 15 can push the pushing block 16. When the dial block 15 and the pushing block 16 just come into contact, the pushing block 16 cooperates with the thinner part of the dial block 15. As the dial block 15 rotates, the thicker area of the dial 15 contacts the pushing block 16, thereby pushing the pushing block 16. And when the previous dial block 15 separates from the corresponding pushing block 16, the next dial block 15 can contact the corresponding pushing block 16 to ensure that the tray portion 1 is divided into separate strip structures. The vertical surface of the dial block 15 is a vertical surface, and the length of the vertical surface of the first rotating dial block 15 to the vertical surface of the last rotating dial block 15 decreases in sequence, so that after the tray portion 1 is divided into separate strip structures, each strip structure is separated from each other.

[0048] Starting from the pusher block 15 with the thickest vertical surface thickness, in the early stage of separating the disc part 1, since the separated part is lighter than the unseparated part, the unseparated part can remain relatively stationary under the action of gravity. However, when the splitting operation reaches the end (when separating the two strip structures), pulling one of the strip structures will inevitably cause the two strip structures to move together. Therefore, the following technical solution is provided: The lower end surface of the pusher block 16 in the first fixing block 7 at the end is an arc surface, and there are a transmission wheel 34 and a rotating wheel 33 inside the end block 17 at the end. The arc surface meshes with the transmission wheel 34, and the transmission wheel 34 meshes with the rotating wheel 33. There are two symmetrically arranged push plates 30 inside the end block 17 at the end. The push plates 30 extend into the cross bar 8. A bracket 32 is fixedly connected to the push plate 30. The bracket 32 meshes with the rotating wheel 33, and the push plate 30 is connected to the end block 17 through a second spring 31. When the pusher block 16 rotates, the lower end of the pusher block 16 can drive the transmission wheel 34 to rotate, and the transmission wheel 34 will drive the rotating wheel 33 to rotate. The brackets 32 are located on both sides of the rotating wheel 33, so the two push plates 30 can move away from each other to separate the two strip structures. In some embodiments, the pusher block 16 can directly cooperate with the rotating wheel 33 without the use of the transmission wheel 34.

[0049] Of course, when implementing this device, in order to ensure that each strip structure can be separated, the structure of each cross bar 8 can be set in this way, that is, each cross bar 8 has a structure with two push plates 30 inside.

[0050] A first spring 26 is provided between the first fixing block 7 and the end block 17 so that the first fixing block 7 can be reset. The cooperation relationship between the first rotating rod 5, the cross bar 8 and the second rotating rod 9, the vertical rod 11 is the same, that is, the structure of the horizontal separating member and the vertical separating member is the same.

[0051] It further includes an outer frame 18. A horizontal slideway is provided inside the outer frame 18. The bottom lining plate 3 is located in the horizontal slideway. A fixing plate 23 is fixedly connected to the inner wall of the horizontal slideway. The slider 4 is located above the fixing plate 23. A plurality of through holes 24 are provided in the fixing plate 23. The slider 4 can slide down along the through holes 24. A lead screw 27 is provided inside the outer frame 18. A threaded block 28 is sleeved on the lead screw 27. A limiting block 29 is fixedly connected to the threaded block 28. The limiting block 29 cooperates with the slider 4. When the lead screw 27 rotates, the threaded block 28 can slide to drive the slider 4 to slide.

[0052] A first toggle block 19a and a second toggle block 19b are fixedly connected to the inner wall of the transverse slide. The first toggle block 19a and the second toggle block 19b can cooperate with the first tooth portion 6 to rotate the first tooth portion 6. The first tooth portion 6 is fixedly connected to the end of the first rotating rod 5 so that the first tooth portion 6 drives the first rotating rod 5 to rotate. A vertical tooth portion 25 is also provided on the inner wall of the transverse slide. The second tooth portion 10 at the end of the second rotating rod 9 can cooperate with the vertical tooth portion 25 so that when the bottom lining plate 3 moves downward, the second tooth portion 10 can drive the second rotating rod 9 to rotate.

[0053] A support rod 20 is fixedly connected to the first fixed block 7. The end of the support rod 20 is rectangular, and a rectangular groove is provided in the transverse slide to prevent the support rod 20 from rotating with the first rotating rod 5. At the same time, when the bottom lining plate 3 moves downward, the support rod 20 can also fix the position of the first rotating rod 5 and the cross bar 8 to prevent them from moving downward together.

[0054] The transverse slide also has a movable plate 21, the upper end of the movable plate 21 is fixedly connected with a block 22, and a slot 13 is provided at the lower end of the bottom lining plate 3. The block 22 cooperates with the slot 13 so that the bottom lining plate 3 can move up and down with the movable plate 21, that is, when the block 22 cooperates with the slot 13, when the movable plate 21 moves downward, the movable plate 21 can pull the bottom lining plate 3 to move downward, and a lifting member is provided at the lower end of the movable plate 21.

[0055] A method for raising seedlings using a straw-degradable nutrient seedling raising tray comprises the following steps:

[0056] Step 1: put the cultivation soil into the tray unit 2 and plant the seeds into the tray unit 2.

[0057] Step 2: When the seedlings need to be transplanted, the tray 1 is placed on the bottom lining plate 3, and the bottom lining plate 3 slides in the transverse slideway.

[0058] Step 3: During the sliding process, the disk portion 1 is first divided into strip-shaped units, and then the strip-shaped units are divided into individual disk units 2.

[0059] Step 4: transplant the seedlings in the tray unit 2.
