Description

Technical Field

[0001] The utility model relates to the technical field of greening planting, in particular to a planting hole structure and a planting hole drilling tool. Background Art

[0002] At present, open-pit sand and stone mines are gradually being reclaimed and greened to restore the natural mountain environment. Because the geology is composed of slag after mining, the slag matrix makes it difficult for rainwater and irrigation water to collect and retain water in the planting holes, resulting in serious soil and water loss. The one-time survival rate of seedlings after planting is only about 60%;

[0003] The mountain formed after the construction of the power line towers is a layer of fallen slag, with uneven slopes and very few flat surfaces. Combined with the slag matrix, the water collection and retention effect of the planting holes is poor, and soil erosion is more serious than the reclamation and greening of open-pit sand and gravel mines. The one-time survival rate of the seedlings after planting is only about 50%;

[0004] Planting seedlings in the above environment has a low survival rate and requires multiple replanting, which consumes manpower, time and money.

[0005] In actual construction, holes are usually dug manually with a shovel, and then the seedlings removed from the pots are placed in the holes. The roots of the seedlings removed from the pots are separated from the original mother soil, which greatly reduces the survival rate. A large amount of foreign soil needs to be backfilled, and the transportation of foreign soil is also inconvenient. Due to the gravel matrix, digging the planting holes is also very laborious.

[0006] Therefore, there is an urgent need for a planting hole structure that can reduce soil erosion, improve the one-time survival rate of reclaimed greening seedlings, and reduce backfill soil, as well as a labor-saving tool for digging planting holes. Utility Model Content

[0007] The purpose of the utility model is to solve the deficiencies of the above-mentioned prior art and to provide a planting hole structure with a simple structure, which reduces soil erosion, improves the one-time survival rate of reclaimed greening seedlings, reduces the backfill of foreign soil, and a labor-saving planting hole digging drill.

[0010] Insert the seedling pot into the seedling pot layer, use the pot without removing the planting pot, retain the original mother soil in the pot, can reduce the refill of foreign soil, at the same time the seedling root system does not separate from the original mother soil, improve the survival rate of the seedling; the water storage layer at the bottom of the seedling pot allows rainwater and irrigation water to infiltrate and store water to moisten the roots of the seedlings. Due to the different slopes of the mountain and the gravel matrix, a water collection layer is set above the seedling pot to collect water, increase the water storage capacity, and the setting of the water collection layer and the water storage layer ensures the water collection and water conservation effect, and improves the survival rate of the seedlings.

[0011] The seedling pot layer of the utility model is matched with the size of the seedling pot; it not only reduces the backfilling of foreign soil, but also can form a seal for the water storage layer, so that the water storage layer produces a negative pressure effect, and the water in the water storage layer seeps out slowly, prolonging the moistening period of the roots of the seedlings. At the same time, water will also seep into the water storage layer from the periphery of the water storage layer, and the surrounding mud and sand will gradually seep into the water storage layer to form a new root matrix, thereby promoting the growth and stabilization of the new root system of the seedlings.

[0012] The water collection layer of the utility model is provided with a diversion slope inclined from top to bottom and inward, so that water can flow into the water collection layer along the diversion slope, which is convenient for collecting rainwater and irrigation water, reduces loss, and increases water storage capacity.

[0013] The seedling pot body layer and the seedling pot body of the utility model are in the shape of an inverted frustum.

[0014] The angle formed between the diversion slope of the water collection layer and the horizontal plane is θ1, and the angle formed between the slope of the seedling pot layer and the horizontal plane is θ2, and θ1 is smaller than θ2; so that the slope of the diversion slope is gentler, thereby increasing the water collection capacity.

[0017] The water collecting part and the bowl body part of the utility model are in the shape of an inverted frustum.

[0018] The angle formed between the inclined surface of the water-collecting part and the horizontal plane of the utility model is θ1, and the angle formed between the inclined surface of the bowl body part and the horizontal plane is θ2, and θ1 is smaller than θ2; thus, the slope of the water-collecting part after impact is gentler than the slope of the bowl body part, and soil is not brought out when the drill is lifted, while also increasing the water collection capacity of the water collection layer of the planting hole.

[0019] The bottom of the water storage part of the utility model is provided with a guiding inclined surface which is inclined from top to bottom and inwards; the setting of the guiding inclined surface plays a guiding role, which is convenient for impact drilling.

[0029] The present invention will be described below with reference to the accompanying drawings and embodiments.

[0030] As attached Figure 2-3As shown, a planting hole structure, the planting hole 2 includes a water collection layer 201, a seedling pot layer 202 and a water storage layer 203, the water collection layer 201, the seedling pot layer 202, and the water storage layer 203 are connected from top to bottom, and the seedling pot 3 is placed in the seedling pot layer 202;

[0031] The seedling pot 3 is inserted into the seedling pot layer 202, and the pot is not removed for planting, and the original mother soil in the pot is retained, which can reduce the refilling of foreign soil. At the same time, the seedling root system does not separate from the original mother soil, thereby improving the survival rate of the seedlings; the water storage layer 203 at the bottom of the seedling pot 3 allows rainwater and irrigation water to infiltrate and store water to moisten the roots of the seedlings. Due to the different slopes of the mountain and the gravel matrix, a water collection layer 201 is set above the seedling pot 3 for collecting water, thereby increasing the water storage capacity. The setting of the water collection layer 201 and the water storage layer 203 ensures the water collection and water conservation effect, thereby improving the survival rate of the seedlings.

[0032] The inner diameter of the seedling pot layer 202 is matched with the outer diameter of the seedling pot 3; it not only reduces the backfill of imported soil, but also can make the water storage layer 203 form a seal, so that the water storage layer 203 produces a negative pressure effect. The pressure in the water storage layer is lower than the surrounding environmental pressure, and the water in the water storage layer 203 seeps out slowly, extending the moistening period of the seedling roots. At the same time, water will also seep into the water storage layer 203 from the surrounding area, and the surrounding mud and sand will gradually seep into the water storage layer 203, forming a new root matrix, which promotes the growth and stabilization of the new root system of the seedlings.

[0033] In this embodiment, the seedling pot layer 202 and the seedling pot 3 are in the shape of an inverted cone, and the seedling pot 3 is inserted into the seedling pot layer 202.

[0034] The water collection layer 201 is provided with a diversion slope 2011 that slopes downward and inward from top to bottom, so that water can flow into the water collection layer along the diversion slope 2011, thereby facilitating the collection of rainwater and irrigation water, reducing loss, and increasing the amount of water collected.

[0035] In this embodiment, the water-collecting layer 201 is shaped like an inverted cone, and the water storage layer 203 is shaped like a cylinder. The large diameter end of the water-collecting layer is connected to the ground 4, the small diameter end of the water-collecting layer 201 is connected to the large diameter end of the seedling pot layer 202, and the small diameter end of the seedling pot layer 202 is connected to the upper end of the water storage layer 203.

[0036] like Figure 2 As shown, the angle formed between the diversion slope 2011 of the water collection layer 201 and the horizontal plane is θ1, and the angle formed between the slope of the seedling pot layer 202 and the horizontal plane is θ2, and θ1 is smaller than θ2; so that the slope of the diversion slope is gentler, thereby increasing the water collection capacity.

[0037] The seedling pot body 3 is made of degradable materials to prevent pollution to the environment.

[0038] like Figure 1 As shown, a planting hole drilling tool is used to impact to form the planting hole 2 as described above, including an impact device connecting part 101, a water collecting part 102, a bowl part 103 and a water storage part 104. The impact device connecting part 101, the water collecting part 102, the bowl part 103 and the water storage part 104 are connected and arranged in sequence from top to bottom; the water collecting part 102, the bowl part 103 and the water storage part 104 are coaxially arranged, and the structure is simple. The planting hole is formed by impact, and digging the planting hole saves labor.

[0039] In this embodiment, the planting hole-opening drill tool is made of an integral molding and is forged with No. 45 manganese steel. The size of the pot part of the planting hole-opening drill tool is designed according to the size of the seedling pot. The impact device connection part 101 is connected to the impact device (excavator, jackhammer, etc.). The structure of the impact device and the connection between the impact device and the drill tool are existing technologies and will not be described in detail here.

[0040] The water collecting part 102 and the bowl part 103 are in the shape of an inverted cone. The water storage part includes a columnar section and a guide section. The columnar section is arranged at the upper end of the guide section. The guide section is in the shape of an inverted cone and is provided with a guide slope 1041 inclined from top to bottom and inward, which plays a guiding role and facilitates impact drilling.

[0041] The small diameter end of the water collecting part 102 is connected to the large diameter end of the bowl part 103, the small diameter end of the bowl part 103 is connected to the upper end of the columnar section, and the lower end of the columnar section is connected to the large diameter end of the guide section.

[0042] like Figure 1 As shown, the angle formed between the inclined surface of the water-collecting part 102 and the horizontal plane is θ1, and the angle formed between the inclined surface of the bowl part 103 and the horizontal plane is θ2, and θ1 is smaller than θ2; so that the slope of the water-collecting part 102 is gentler than the slope of the bowl part 103 after impact, and no soil is brought out when the drill is lifted, and the water collection capacity of the water collection layer of the planting hole is also increased.

[0043] When using this utility model:

[0044] 1. Connect the planting hole drilling tool 1 to the impact device through the impact device connection part 101. The impact device drives the planting hole drilling tool 1 to impact downward on the gravel matrix ground 4 to form a planting hole 2.

[0045] 2. Insert the seedling pot 3 and the seedlings 5 ​​planted in the seedling pot 3 into the seedling pot layer 202 of the planting hole 2. No need to backfill with foreign soil. After the seedling pot 3 is inserted, the water storage layer 203 is sealed;

[0046] 3. After rainfall or artificial watering, water enters the water collection layer 201 and slowly seeps into the water storage layer 203 through the seedling pot 3. The pressure in the water storage layer 203 is lower than the ambient pressure, which slows down the speed at which water in the water storage layer 203 seeps outward, prolongs the moistening period of the seedling roots, and attracts the roots in the seedling pot 3 to extend downward through the drainage and air vents of the seedling pot 3. The mud and sand that gradually seep into the surrounding area of ​​the water storage layer 203 form a new matrix for the growth and fixation of new roots, thereby improving the one-time survival rate of the reclaimed greening seedlings.
