Abstract
Description
Technical Field
[0001] This utility model relates to the field of blueberry cultivation technology, specifically to a blueberry cultivation and seedling raising device. Background Technology
[0002] Blueberries, as a small berry tree species with high economic value and broad development prospects, have a sweet and sour taste. The nutrients they contain can play a positive role in preventing brain nerve aging, protecting eyesight, strengthening the heart, fighting cancer, softening blood vessels, and enhancing human immune function, and are therefore very popular among consumers.
[0003] Currently, as blueberries gain increasing recognition from consumers, their economic value is constantly rising, which in turn drives the rapid development of the blueberry planting industry. However, there are still many areas for improvement in the corresponding blueberry planting equipment. For example, the tray devices used for blueberry seedling cultivation are mostly simple snap-fit assemblies, which have poor stability and increase the chance of separation during transfer and transportation, thereby damaging the blueberry seedlings. The effectiveness of their use still needs further optimization. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a blueberry planting and seedling raising device, which solves the problems mentioned in the background section.
[0005] This utility model provides the following technical solution: a blueberry planting and seedling raising device, including a bottom tray and a combination tray. Several assembly holes are provided in the top corners of the bottom tray and the top corners of the combination tray. The bottom of the combination tray is connected to a composite support rod that fits into the assembly holes corresponding to the bottom of the bottom tray. The bottom structure of the composite support rod has a positioning hole that communicates with the corresponding assembly hole.
[0006] Both the corner structure of the bottom tray and the corner structure of the combined tray are fitted with elastic limiting rods, and one end of the elastic limiting rod can pass through the side of the bottom tray or the side of the combined tray and be engaged with the corresponding positioning hole.
[0007] Specifically, the elastic limiting rod includes a T-shaped rod body and a first return spring. The corner structures of the bottom tray and the combined tray are provided with clearance holes. One end of the T-shaped rod body can pass through the clearance hole and the assembly hole in sequence and be engaged in the corresponding positioning hole. The first return spring is sleeved on the outside of the other end of the T-shaped rod body, and one end of the first return spring is fixedly connected to the surface of the corresponding combined tray or the surface of the corresponding bottom tray. The other end of the first return spring is fixed to the surface of the other end of the T-shaped rod body.
[0008] Preferably, a limiting component is provided on the outer side of the other end of the T-shaped rod. The limiting component includes an adjusting rod, a limiting frame plate, and an arc-shaped sleeve plate. One end of the adjusting rod is fitted onto the inner side of the other end of the T-shaped rod through a bearing, and the limiting frame plate is movably sleeved on the outer side of the other end of the T-shaped rod and fixedly connected to the middle structure of the adjusting rod. The limiting frame plate can be snapped together with the arc-shaped sleeve plate, and the arc-shaped sleeve plate is fixedly installed on the surface of the corresponding combination pallet or the surface of the corresponding bottom pallet. The limiting component is used to further limit the snap-fit state of the elastic limiting rod.
[0009] In particular, filter plates are fixedly nested on the bottom inner side of the bottom tray and the bottom inner side of the combined tray, and the filter plates have several ventilation holes inside, which provide stable support for the seedlings while providing a good air circulation environment for the seedlings to grow.
[0010] The composite support member includes an external threaded sleeve and a support rod body. The two ends of the support rod body are respectively engaged inside the external threaded sleeve and fixed to the bottom surface of the corresponding position of the combined pallet. The inner and outer sides of the middle of the external threaded sleeve are respectively fitted with two opposing clamping rod components and threadedly connected to an internal threaded sleeve. The top of the internal threaded sleeve is provided with an inverted conical hole, and the internal threaded sleeve can simultaneously squeeze and transmit or disengage the two opposing clamping rod components through the inner wall of its own inverted conical hole. The adjustable use feature of the composite support member itself can provide structural conditions for adjusting the distance between the bottom pallet and the combined pallet.
[0011] The support rod is designed with a square structure in the middle to ensure the contact limiting area. The bottom surface of the support rod is nested with an annular gasket that rubs against the inner wall of the external threaded sleeve to improve the stability of the engagement between the support rod and the external threaded sleeve. The positioning hole is opened on the side wall at the bottom of the external threaded sleeve and is in a through state.
[0012] The clamping rod component comprises an I-shaped rod and a second return spring. The middle part of the I-shaped rod is engaged inside the side wall of the external threaded sleeve, and the second return spring is fitted on the outside of one end of the I-shaped rod. The two ends of the second return spring are respectively fixedly connected to the surface of one end of the I-shaped rod and the inner wall of the external threaded sleeve. After the second return spring is fitted and connected to the support rod body, the second return spring will be in a stretched and expanded state, thereby facilitating the automatic reset of the subsequent displacement of the I-shaped rod. The other end of the I-shaped rod has a spherical structure to optimize the subsequent top pressure transmission.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This utility model uses an elastic limiting rod and a limiting component to form a multi-functional limiting structure. After being combined with a bottom tray, a combined tray, and a composite support rod between the bottom tray and the combined tray, the bottom tray and the composite support rod can be mechanically limited and locked by pressing the elastic limiting rod and then turning the limiting component to adjust the connection. This ensures the assembly and connection strength of the bottom tray, the combined tray, and the composite support rod.
[0015] 2. The composite support rod of this utility model has a self-adjusting function. During the subsequent adjustment of the gap between the bottom tray and the combined tray, it is only necessary to rotate the internal threaded sleeve inside the composite support rod, so that the internal threaded sleeve moves up and down on the external threaded sleeve, making room for the reset movement of the corresponding two clamping rod components, thereby releasing the clamping constraint on the support rod. Then, the combined tray can be directly lifted, so that the combined tray, guided by multiple external threaded sleeves and their respective corresponding support rods, adjusts the gap between the combined tray and the bottom tray. After completion, the internal threaded sleeve is reset, which restores the compression transmission of the two clamping rod components, so that the two clamping rod components re-clamp and limit the adjusted support rod. The whole process is simple and flexible. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 A blueberry planting and seedling raising device includes a base tray 1 and a combination tray 2. Several assembly holes are provided in the top corners of the base tray 1 and the top corners of the combination tray 2. The bottom of the combination tray 2 is connected to a composite support rod 5 that fits into the assembly holes corresponding to the bottom of the base tray 1. The bottom structure of the composite support rod 5 has a positioning hole that communicates with the corresponding assembly hole space. The corner structures of the base tray 1 and the corner structures of the combination tray 2 are fitted with elastic limiting rods 3, and one end of the elastic limiting rod 3 can pass through the side of the base tray 1 or the side of the combination tray 2 and be engaged with the corresponding positioning hole.
[0025] The elastic limiting rod 3 includes a T-shaped rod body 31 and a first return spring 32. Both the corner structures of the bottom tray 1 and the combined tray 2 have clearance holes. One end of the T-shaped rod body 31 can pass through the clearance hole and the assembly hole sequentially and be engaged in the corresponding positioning hole. The first return spring 32 is fitted onto the outside of the other end of the T-shaped rod body 31, and one end of the first return spring 32 is fixedly connected to the surface of the corresponding combined tray 2 or the corresponding bottom tray 1. The other end of the first return spring 32 is fixed to the surface of the other end of the T-shaped rod body 31. A limiting component 4 is provided on the outside. The limiting component 4 includes an adjusting rod 41, a limiting frame plate 42, and an arc-shaped sleeve plate 43. One end of the adjusting rod 41 is fitted onto the inner side of the other end of the T-shaped rod 31 through a bearing. The limiting frame plate 42 is movably sleeved on the outer side of the other end of the T-shaped rod 31 and fixedly connected to the middle structure of the adjusting rod 41. The limiting frame plate 42 can be snapped and assembled with the arc-shaped sleeve plate 43. The arc-shaped sleeve plate 43 is fixedly installed on the surface of the corresponding combination pallet 2 or the surface of the corresponding bottom pallet 1. The limiting component 4 is used to further limit the snap-fit state of the elastic limiting rod 3.
[0026] The bottom inner side of the bottom tray 1 and the bottom inner side of the combined tray 2 are both fixedly nested with filter plates 6, and the filter plates 6 have several ventilation holes inside, which provide stable support for the seedlings and provide a good air circulation environment for the seedlings to grow.
[0027] Specific usage of this embodiment:
[0028] For the assembly and use of the base tray 1 and the combined tray 2, multiple composite support rods 5 set at the bottom of the combined tray 2 can be simultaneously snapped into the corresponding number of assembly holes inside the base tray 1. Then, the elastic limiting rod 3 is pushed as a whole, so that the T-shaped rod 31 inside the elastic limiting rod 3 passes through the corresponding clearance hole and assembly hole in sequence and is snapped into the corresponding positioning hole. At this time, the first return spring 32 is in a compressed state, thereby limiting the position of the base tray 1 and the composite support rods 5.
[0029] To ensure the stability and locking of the elastic limit rod 3, the adjusting rod 41 corresponding to the elastic limit rod 3 is turned, which in turn causes the adjusting rod 41 to drive the limiting frame plate 42 to engage and overlap with the arc-shaped sleeve plate 43. Thus, the structural overlap between the adjusting rod 41 and the limiting frame plate 42 counteracts the elastic reset of the first reset spring 32, ensuring the stability of the elastic limit rod 3 for a long time. The remaining elastic limit rods 3 and their corresponding limiting components 4 are then operated in accordance with the above steps.
[0030] Please see Figure 5-6 The composite support rod 5 includes an external threaded sleeve 51 and a support rod body 52. The two ends of the support rod body 52 are respectively snapped into the inside of the external threaded sleeve 51 and fixed on the bottom surface of the corresponding position of the combined pallet 2. The middle inner side and the outer side of the external threaded sleeve 51 are respectively fitted with two opposing clamping rod parts 53 and an internal threaded sleeve 54 threadedly connected. The top of the internal threaded sleeve 54 is provided with an inverted conical hole, and the internal threaded sleeve 54 can simultaneously squeeze and transmit or disengage the two opposing clamping rod parts 53 through the inner wall of its own inverted conical hole. The adjustable use feature of the composite support rod 5 itself can provide structural conditions for adjusting the distance between the bottom pallet 1 and the combined pallet 2.
[0031] The middle part of the support rod 52 is designed with a square structure to ensure the subsequent contact limiting area. An annular washer 7 is nested on the bottom surface of the support rod 52 to rub against the inner wall of the external threaded sleeve 51, improving the stability of the engagement between the support rod 52 and the external threaded sleeve 51. A positioning hole is opened on the side wall at the bottom of the external threaded sleeve 51 and is in a through-hole state. The clamping rod component 53 includes an I-shaped rod 531 and a second return spring 532. The middle part of the I-shaped rod 531 is engaged within the side wall of the external threaded sleeve 51. The second return spring 532 is fitted on the outer side of one end of the I-shaped rod 531, and the two ends of the second return spring 532 are respectively fixedly connected to the surface of one end of the I-shaped rod 531 and the inner wall of the external threaded sleeve 51. After the second return spring 532 is attached to the support rod body 52, the second return spring 532 will be in a stretched and expanded state, which facilitates the automatic reset of the subsequent displacement of the I-shaped rod 531. The other end of the I-shaped rod 531 is a spherical structure, which optimizes the subsequent top pressure transmission.
[0032] Specific usage of this embodiment:
[0033] When it is necessary to adjust the spacing between the bottom tray 1 and the combined tray 2, the internal threaded sleeve 54 inside the composite support rod 5 can be screwed in, thereby causing the internal threaded sleeve 54 to move up and down on the external threaded sleeve 51, thus making room for the reset movement of the corresponding two clamping rod components 53. Subsequently, the I-shaped rods 531 inside the two clamping rod components 53 will move away from the support rod body 52 by their respective second reset springs 532, thereby releasing the clamping constraint on the support rod body 52.
[0034] After the remaining composite support rods 5 have been operated according to the above steps, the combined pallet 2 can be directly lifted, so that the combined pallet 2, guided by multiple external threaded sleeves 51 and their corresponding support rods 52, adjusts the spacing of the bottom pallet 1. After completion, the internal threaded sleeves 54 are reset, and then the pressing transmission of the two clamping rod components 53 is restored, so that the two clamping rod components 53 re-clamp and limit the adjusted support rods 52.
