Description

TECHNICAL FIELD

[0001] The present application relates to the field of soilless culture, in particular to a soilless cultivation equipment for forestry seedling planting facilitating seedling lifting. BACKGROUND

[0002] With the increasing efforts of global ecological environment construction and the rapid development of forestry industry, the demand for high-quality seedlings is increasing, and the scientificity and efficiency of seedling cultivation technology directly affect the quality and effectiveness of forestry engineering. Traditional seedling cultivation relies on soil cultivation mode, which is limited by soil fertility, pests and diseases, heavy cropping obstacles and other factors, which easily leads to uneven seedling growth, poor stress resistance, and long cultivation period, which is difficult to meet the demand for large-scale and standardized seedling supply.

[0003] Under this background, soilless cultivation technology gradually becomes the mainstream direction of forestry seedling cultivation due to its strong controllability, high resource utilization rate and rapid seedling growth, but the existing soilless cultivation equipment in practical application faces many technical problems. On the one hand, most of the seedling containers have significant shortcomings in the fixation of the roots during cultivation. The inner wall is mostly smooth curved structure, which cannot effectively limit the substrate. If the irrigation impact or slight external force shaking occurs, the substrate is prone to settle and form gaps with the inner wall of the container, which leads to the loss of stable support for the root system. On the other hand, seedlings need to be manually peeled off the container or pried off the substrate block, and some need to cut the container. Not only is the operation time-consuming and laborious, but also the cutting process is prone to root fracture, even reduces the transplanting survival rate, and the seedling lifting efficiency is low, which cannot match the production rhythm of intensive seedling cultivation and cannot meet the actual use needs.

[0004] Therefore, it is necessary to provide a soilless cultivation equipment for forestry seedling planting facilitating seedling lifting, which aims to solve the above problems. SUMMARY

[0005] In view of the deficiencies in the prior art, the purpose of the embodiments of the present application is to provide a soilless cultivation equipment for forestry seedling planting facilitating seedling lifting, which aims to solve the technical problems proposed in the background art.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0007] A soilless cultivation equipment for forestry seedling planting facilitating seedling lifting, comprising a seedling container, the number of the seedling container is several and is arranged on a seedling tray, the seedling container is assembled from top to bottom by an upper base, a middle base and a lower base, further comprising:

[0012] As a further scheme of the present application, the seedling root limiting mechanism further comprises a reset tension spring for driving the driving lever to reset, wherein the upper base is provided with a driving groove for matching the driving lever, the driving lever is provided with the reset tension spring at the side connected with the driving groove, and the side of the driving lever is provided with an arc-shaped edge.

[0013] As a further scheme of the present application, the limiting trigger seedling raising mechanism further comprises a driving piece for limiting and abutting the traction of the driving lever, wherein the limiting trigger lever is movably connected with the upper base through the driving piece, the upper base is provided with a strip-shaped groove for matching the driving piece, the limiting trigger lever is provided with a reset spring on one side, and the head of the limiting trigger lever is arc-shaped.

[0016] In summary, the embodiments of the present application have the following beneficial effects compared with the prior art:

[0017] The positioning structure of the conventional soilless cultivation container is mostly designed by bolt fixing or buckle splicing, and tools are needed to disassemble the parts when placing seedlings, which is complicated and time-consuming, greatly reducing the planting efficiency.

[0018] In traditional soilless cultivation of forestry seedlings, seedling lifting is mostly dependent on manual stripping of the cultivation substrate, prying the container or directly lifting the seedling, which not only requires the operator to exert great physical effort, but also requires high operating skills.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical scheme and advantages of the application more clear, the application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the application and not to limit the application.

[0035] The specific implementation of the application is described in detail below in combination with specific examples.

[0036] Referring to Figures 1-13 A soilless cultivation equipment for forestry seedling planting facilitating seedling, comprising a seedling container 1, the number of the seedling container 1 is several and all are arranged on a seedling tray 2, the seedling container 1 is assembled from top to bottom by an upper base 5, a middle base 6 and a lower base 7, further comprising:

[0037] The seedling root limiting mechanism is installed on the seedling container 1 and used for limiting and abutting the seedling roots. The seedling root limiting mechanism comprises a positioning block 9 for abutting and limiting and a push rod 16 for driving the positioning block 9 to abut and limit. An upper base 5 is provided with a seedling placing hole 4 for placing seedlings. The positioning block 9 is provided with a protective sleeve 10 on one side for clamping protection. The positioning block 9 is positioned by the push rod 16.

[0038] Further, the seedling root limiting mechanism further comprises a rotating disc 15 for driving the positioning block 9 to position and adjust. The rotating disc 15 is rotationally installed in the upper base 5. The positioning block 9 is provided with a moving slider 12 below the right angle side. The rotating disc 15 is provided with a guide sliding groove 14 for sliding connection with the moving slider 12.

[0039] Further, the seedling root limiting mechanism further comprises a guide rod 11 for driving the positioning block 9 to rotate. The guide rod 11 is fixedly installed on the positioning block 9 and located at the center of the side of the positioning block 9. The upper base 5 is provided with a positioning groove 13 for sliding connection with the guide rod 11. The positioning groove 13 is provided with a first area 24 and a second area 25.

[0040] Further, the seedling root limiting mechanism further comprises a reset tension spring 18 for driving the push rod 16 to reset. The upper base 5 is provided with a push groove 19 for sliding connection with the push rod 16. The push rod 16 is provided with the reset tension spring 18 at the side connection with the push groove 19. The side of the push rod 16 is provided with an arc-shaped edge.

[0041] Further, the protective sleeve 10 is made of elastic rubber. The bottom of the lower base 7 is provided with a plurality of drainage holes 3 for drainage.

[0042] Preferably, the seedling tray 2 is provided with a plurality of seedling containers 1, thereby facilitating the cultivation of a certain number of forestry seedlings, and the seedling containers 1 are correspondingly provided with seedling placing holes 4 for placing seedlings. During the cultivation stage, the rotating disc 15 is rotated by the hand-held lever 16 to approach the limiting touch rod 20. When the limiting hole 17 below the lever 16 contacts the limiting touch rod 20, the limiting touch rod 20 is inserted into the limiting hole 17 under the action of the arc-shaped edges of the lever 16 and the limiting touch rod 20, and at this time, the positioning block 9 is rotated and opened to the maximum position. Accordingly, the forestry seedlings can be placed in the seedling containers 1 at this time. Then, the limiting touch rod 20 on the lever 16 is lowered and reset, and at this time, the lever 16 is reset under the elastic traction of the reset tension spring 18. Thus, the positioning block 9 is automatically returned to the position for clamping and positioning the forestry seedlings. The protective sleeve 10 on the positioning block 9 facilitates the positioning and protection of the roots of the forestry seedlings, so that the roots of the forestry seedlings are better fixed. At this time, the guide rod 11 on the positioning block 9 moves from the second area 25 to the first area 24, as shown in Figure 10 and Figure 12 .

[0043] The convenient opening and closing of the positioning block 9 is realized by the linkage of the lever 16 and the reset tension spring 18, which significantly reduces the operation difficulty of placing seedlings. The positioning structure of traditional soilless cultivation containers is mostly designed by bolt fixation or buckle splicing. When placing seedlings, tools are needed to disassemble the parts, which is tedious and time-consuming, and greatly reduces the planting efficiency. However, the mechanical linkage design of the lever and the elastic traction of the reset tension spring greatly simplifies the seedling placing process, and realizes the scientific fixation and protection of the roots of the seedlings, taking into account the production practicability and seedling cultivation quality. It provides efficient and reliable equipment support for soilless cultivation of forestry seedlings, effectively solving the problems of inconvenient seedling placement and unstable root fixation in traditional soilless cultivation equipment.

[0044] As shown in Figures 1-13 , the limiting touch trigger seedling lifting mechanism is installed on the seedling container 1 and is used for lifting the seedlings. The limiting touch trigger seedling lifting mechanism includes a limiting touch rod 20 for lifting the seedlings. The lever 16 is provided with a limiting hole 17 that is adapted to the limiting touch rod 20. The limiting hole 17 is provided with a proximity switch that is adapted to the limiting touch rod 20. The limiting touch rod 20 is movably installed on the upper base 5.

[0045] Further, the position-limiting trigger seedling raising mechanism further comprises a push piece 21 for position-limiting abutment of the pulling of the push rod 16, the position-limiting trigger 20 is slidably connected to the upper base 5 through the push piece 21, the upper base 5 is provided with a strip-shaped slot 23 adapted to the sliding connection of the push piece 21, and the position-limiting trigger 20 is provided with a reset spring 22 on one side, and the head of the position-limiting trigger 20 is arc-shaped.

[0046] Further, the position-limiting trigger seedling raising mechanism further comprises an electric push rod 8 for seedling lifting, the lower part of the upper base 5 is provided with a middle base 6, the middle base 6 is limitingly sleeved and installed on the lower base 7, and the electric push rod 8 is fixedly installed in the inside of the lower base 7, and the piston rod of the electric push rod 8 is connected with the inside of the middle base 6.

[0047] Preferably, in the embodiment, when seedling raising is needed, the corresponding position-limiting trigger is achieved by pushing the push rod 16 to the position-limiting trigger 20, and since the inside of the position-limiting hole 17 is provided with a proximity switch adapted to the abutment of the position-limiting trigger 20, when the positioning block 9 is completely opened, the electric push rod 8 is driven to move in contraction under the abutment relationship between the position-limiting trigger 20 and the proximity switch in the position-limiting hole 17, and at this time, the upper base 5 and the middle base 6 are correspondingly lowered, so that the forestry seedling roots are pushed out at this time, the seedling raising is simple, and it is convenient for soilless cultivation.

[0048] In traditional soilless cultivation of forestry seedlings, seedling raising is mostly dependent on manual stripping of the cultivation substrate, prying of the container or direct lifting of the seedlings, which not only requires a large amount of physical labor of the operator, but also requires high operating skills. The device simplifies the complex seedling raising operation to a single operation of "push rod pushing", greatly reduces the difficulty and intensity of manual participation, makes the forestry seedlings more easily raised, simplifies the seedling raising operation and reduces the artificial threshold, significantly improves the seedling raising efficiency and transplanting survival rate, realizes the efficiency leap of batch seedling raising operation, effectively reduces the comprehensive cost of forestry seedling raising, provides efficient and reliable technical support for large-scale and standardized cultivation of forestry seedlings, and has outstanding practical value and economic benefits.

[0049] It should be particularly noted that the components in the present application are all general standard components or components known to those skilled in the art, which effectively solve the technical problems proposed in the background art.

[0050] The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
