Description

Technical Field

[0001] This utility model relates to the field of seedling cultivation, and in particular to an irrigation device for forestry seedling cultivation. Background Technology

[0002] In arid regions, if the soil moisture content before sowing is less than 60% of field capacity, small seeds (such as poplar, willow, and paulownia) are prone to germination failure due to insufficient water absorption. Studies have shown that for seeds with a soil covering thickness of less than 2 cm, irrigation before sowing can increase the germination rate by 40%-60%. Irrigation before seedling cultivation can pre-moisten the soil, preventing the formation of a compacted layer due to drying and shrinkage after sowing, and increasing the seedling survival rate.

[0003] However, soil that has not been loosened has reduced porosity due to long-term compaction or natural settling, resulting in weak water permeability. Water cannot penetrate to the bottom layer, and the deep soil remains dry. This does not improve soil compaction and leads to water shortage in the roots after seed germination.

[0004] Therefore, there is a need for an irrigation device for forestry seedling cultivation that can loosen the soil while pre-irrigating. Utility Model Content

[0005] In view of this, the present invention aims to provide an irrigation device for forestry seedling cultivation to solve the problems in the prior art.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] An irrigation device for forestry seedling cultivation includes a receiving plate and a fixing frame fixedly installed on the top of the receiving plate. A cylinder is fixedly installed on the fixing frame. The end of the cylinder extends through to the bottom of the receiving plate and is fixedly connected to the mounting plate. Multiple irrigation covers are fixedly installed at intervals on the bottom of the mounting plate through connecting columns. Each irrigation cover has an inner cavity. Two adjacent irrigation covers are connected by a connecting pipe. Multiple water spray holes are opened at intervals around the outline of the lower part of the inner side wall of the irrigation cover.

[0008] A water storage container is fixedly installed on the top of the receiving plate, and the water storage container is connected to one of the irrigation covers through a connecting pipe.

[0009] The receiving plate is also provided with a walking component that drives the receiving plate to move.

[0010] Furthermore, the walking assembly includes a mounting frame and walking wheels. Two sets of mounting frames are symmetrically arranged. The receiving plate is disposed within the mounting frame, and the walking wheels are rotatably disposed at the ends of the mounting frame.

[0011] Furthermore, the receiving plate is slidably connected within the mounting frame, and the mounting frame has multiple through holes spaced apart on both sides in its height direction for inserting pins, with the pins passing through the through holes and being inserted into the receiving plate.

[0012] Furthermore, the bottom of the irrigation cover is provided with multiple protrusions spaced at intervals around its outline, making its bottom serrated.

[0013] Furthermore, a water spray pipe is fixedly installed at the water spray hole, and multiple water-impacting needles are fixedly installed at intervals on the inner side wall of the water spray pipe around its outline.

[0014] Furthermore, a soil loosening component is provided on the front side of the receiving plate. The soil loosening component includes a fixed plate that is fixedly connected to the side wall of the receiving plate. A sliding plate is provided on the fixed plate, and multiple plowing rulers are spaced apart on the bottom surface of the sliding plate.

[0015] Furthermore, the sliding plate and the plowing ruler are connected by multiple buffer components, the buffer components including a sliding column, a spring, and a connecting plate;

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0033] The following will refer to the appendix. Figures 1 to 6 The present invention will be described in detail with reference to the embodiments.

[0034] Overall, this utility model proposes an irrigation device for forestry seedling cultivation, including a receiving plate 1 and a fixing frame 2 fixedly installed on the top of the receiving plate 1. A cylinder 201 is fixedly installed on the fixing frame 2, and the end of the cylinder 201 extends through to the bottom of the receiving plate 1 and is fixedly connected to the mounting plate 203. Multiple irrigation covers 206 are fixedly installed at intervals on the bottom of the mounting plate 203 through connecting columns 207. The irrigation covers 206 have an inner cavity, and two adjacent irrigation covers 206 are connected by a connecting pipe 2061. Multiple water spray holes 2081 are opened at intervals around the lower part of the inner side wall of the irrigation cover 206. A water storage container 205 is fixedly installed on the top of the receiving plate 1, and the water storage container 205 is connected to one of the irrigation covers 206 through a connecting pipe 204. The receiving plate 1 is also provided with a walking component to drive the receiving plate 1 to move.

[0035] In this embodiment, the irrigation cover 206 is driven vertically downward by the cylinder 201, simultaneously completing surface loosening and deep irrigation during the insertion into the soil. A single action achieves dual functions, reducing the time and manpower required for traditional step-by-step operations. The loosened soil area (adjustable depth) created by the downward pressure of the irrigation cover 206 breaks up the compacted layer, enhances soil permeability, and allows water to reach the seed layer or root layer directly, solving the problem of deep soil compaction caused by drought.

[0036] In addition, the water spray holes 2081 are located on the lower inner side of the irrigation cover 206 and are distributed in a ring around the outline. During irrigation, the water flow directly acts on the middle and lower layers of the soil (such as when the seeds are buried at a depth of 2-5cm), reducing surface evaporation loss and improving irrigation efficiency.

[0037] In the specific implementation process, cylinder 201 is activated, pushing the mounting plate 203 and irrigation cover 206 vertically downwards. The irrigation cover 206 is inserted into the soil to a set depth (e.g., adjustable from 5-15cm). During this process, the outer wall of the irrigation cover 206 compresses and loosens the surrounding soil, forming a loose layer and improving permeability. Subsequently, water is injected into the inner cavity of the first irrigation cover 206 through the connecting pipe 204 via a water pump installed inside the water storage container 205. The water flows through the connecting pipe 2061 and is distributed to all irrigation covers 206, finally being released from the spray hole 2081 to moisten the target soil layer. The walking component is driven electrically or manually, moving the receiving plate 1. Since the irrigation cover 206 is always inserted into the soil, the movement of the walking component causes the irrigation cover 206 to loosen the soil and break up compacted soil. During this process, the spray hole 2081 continuously releases water, allowing the water to enter the loosened soil and quickly infiltrate to deeper layers (e.g., 10-20cm), resolving the "wet on top, dry below" contradiction in compacted soil. The 2081 spray nozzles are arranged in a ring to ensure that water is evenly distributed in all directions, avoiding local water accumulation or irrigation blind spots.

[0038] Among them, such as Figure 1 As shown, the walking assembly includes a mounting frame 4 and walking wheels 401. Two sets of mounting frames 4 are symmetrically arranged. The receiving plate 1 is set inside the mounting frame 4, and the walking wheels 401 are rotatably set at the end of the mounting frame 4.

[0039] In this embodiment, the walking wheels 401 are rotated by manual pushing or motor driving, which drives the mounting frame 4 and the entire device to move along the direction of the seedbed, and then brakes and locks when they reach the target work point.

[0040] It should be noted that, in order to facilitate the adjustment of the height of the receiving plate 1 on the mounting frame 4, in this embodiment, as follows: Figure 1 As shown, the receiving plate 1 is slidably connected within the mounting frame 4. Multiple through holes 402 for inserting pins 403 are provided on both sides of the mounting frame 4 at intervals in the height direction. The pins 403 pass through the through holes 402 and are inserted into the receiving plate 1 for connection.

[0041] By inserting the pin 403 into the perforations 402 of different heights, the relative position of the receiving plate 1 in the mounting frame 4 can be quickly adjusted to adapt to the different seed sowing depth requirements (such as shallow irrigation of small seeds at 2-3cm, and loosening of soil at 10-15cm for deep-rooted seedlings).

[0042] As a preferred structure in this embodiment, such as Figure 4 As shown, the bottom of the irrigation cover 206 is provided with multiple protrusions 208 fixed at intervals around its outline, making its bottom serrated. It should be noted that when the irrigation cover 206 is pressed down, the serrated protrusions 208 can break up the compacted soil layer through a cutting action, reducing the resistance to loosening the soil.

[0043] like Figure 5As shown, a water spray pipe 209 is fixedly installed at the aforementioned water spray hole 2081, and multiple water-impacting needles 210 are fixedly installed at intervals on its inner sidewall around the outline of the water spray pipe 209. The water-impacting needles 210 can disperse the water jet sprayed by the water spray pipe 209, forming a scattering effect, which further increases the irrigation effect.

[0044] In addition, a soil loosening component is provided on the front side of the receiving plate 1, such as... Figure 6 As shown, the soil loosening component includes a fixed plate 3 that is fixedly connected to the side wall of the receiving plate 1. A sliding plate 302 is provided on the fixed plate 3, and a plurality of plowing rulers 306 are spaced apart on the bottom surface of the sliding plate 302.

[0045] In practice, the ploughing blades 306 of the soil loosening component cut into the soil at intervals to pre-loosen the soil, break up the surface compacted layer, and form longitudinal grooves, providing a loosening channel for the subsequent irrigation cover 206 operation. The bottom of the irrigation cover 206 is inserted into the soil to further cut the soil, refining the clumps formed by the pre-loosening soil and enhancing water permeability.

[0046] It should be further explained that the sliding plate 302 and the plowing ruler 306 are connected by multiple buffer components, including a sliding post 304, a spring 305, and a connecting plate 303; the plowing ruler 306 is fixedly installed at intervals on the bottom surface of the connecting plate 303, one end of the sliding post 304 is fixedly connected to the top of the connecting plate 303, and the other end is slidably connected to the sliding plate 302, and the spring 305 is fitted on the sliding post 304 and located between the sliding plate 302 and the connecting plate 303.

[0047] In practice, when the plowing ruler 306 encounters a hard object, the impact force is transmitted to the connecting plate 303, pushing the sliding column 304 to slide upward along the guide hole of the sliding plate 302. The spring 305 is further compressed, and the plowing ruler 306 briefly rebounds to avoid a hard collision. After the impact is released, the spring 305 rebounds and pushes the connecting plate 303 and the plowing ruler 306 back to the preset position, and the normal soil loosening operation continues.

[0048] In addition, continue as Figure 6 As shown, in order to facilitate the adjustment of the distance between the plowing ruler 306 and the ground, in this embodiment, the sliding plate 302 is slidably connected to the side wall of the fixed plate 3, and a top plate 301 is fixedly provided on the top of the side wall of the fixed plate 3. A screw 307 is screwed onto the top plate 301, and the bottom end of the screw 307 is rotatably connected to the sliding plate 302. Rotating the screw 307 can drive the sliding plate 302 to slide along its height direction on the fixed plate 3.

[0049] In practice, the height of the sliding plate 302 can be adjusted by rotating the screw 307, which controls the depth of the plowing ruler 306 into the soil and adapts to different seed sowing depths (such as shallow sowing of poplar at 2-3cm and deep sowing of paulownia at 8-10cm).

[0050] It should be understood that the operator can drive the screw 307 to rotate around its own axis by turning the handwheel or wrench. Since the screw 307 is threadedly engaged with the top plate 301, axial displacement is generated during rotation, thereby adjusting the distance between the plowing ruler 306 and the ground.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
