Description

Technical Field

[0001] The invention relates to the technical field of ecological soil restoration, in particular to a device for planting medicinal plant Artemisia frigida for ecological restoration of an open-pit mine dump. Background Art

[0002] An open-pit mine dump is a specific place in mining for discharging waste soil and rocks generated during ore mining. The dump can be divided into a single-step dump, a covered multi-step dump, etc. according to the stacking order. Due to the long-term stacking of waste rock and soil stripped during the mining process, it is easy to cause soil erosion and environmental pollution. Therefore, it is necessary to carry out ecological restoration of the open-pit mine dump to reduce environmental pollution and other problems.

[0003] At present, the main ecological restoration measures for open-pit mine spoil dumps include soil remediation and vegetation restoration. Vegetation restoration refers to the selection of plant species with strong adaptability for planting to promote vegetation coverage and improve the environment.

[0004] Artemisia frigidum is a medicinal plant whose main active ingredients are flavonoids, alkaloids and alkynes, which have pharmacological effects such as hemostasis and detumescence. According to experimental results, the total flavonoid content in Artemisia frigidum grown in soils of different habitats varies significantly. The western region of Inner Mongolia, where the soil is poor, is the best area for growing Artemisia frigidum. At the same time, Artemisia frigidum has a strong adaptability to poor and drought conditions. The root system of Artemisia frigidum helps prevent soil erosion and improve soil stability, promotes vegetation coverage and provides growth conditions for subsequent vegetation, and gradually improves soil quality. Therefore, it is very suitable for open-pit mine dumps in desert areas of Inner Mongolia.

[0005] When planting Artemisia frigida, it is generally carried out in a row sowing manner through planting equipment. First, the soil is turned over by using a furrow opener, and a sowing furrow is dug. The excavated soil is distributed on both sides of the sowing furrow, and then sowing and fertilization are carried out. Finally, the soil accumulated on both sides of the sowing furrow is backfilled into the sowing furrow through the covering wheel. However, since the soil in the open-pit mine spoil dump contains a lot of waste rock, during backfilling, these stones will not only interfere with the structure of the soil, affecting the air permeability and water retention of the soil, but also may damage the root system of the plant, affecting the normal growth and development of the plant, making it difficult to ensure the quality of the soil and the growth environment of the plant.

[0006] In order to be able to lift and screen the stones in the soil during backfilling, some current planting equipment will add some screening structures between the furrow opener and the covering wheel. The screening structure is usually composed of a screening slot, and screening holes are opened at the bottom of the screening slot. Soil and stones are sent into the screening slot as the vehicle moves, and the soil is screened out through the screening holes, while the stones are retained inside. However, as the stones accumulate, this screening method will gradually block the screening holes, thereby affecting the soil screening process. For example, the patent with publication number CN212573456U discloses a process of screening soil and stones using a stone collecting piece. During the specific screening, the soil and smaller stones are passed through the gaps of the strip through holes, and the larger stones are intercepted and retained in the slot. However, as the stones accumulate, the strip through holes will gradually be blocked. Summary of the invention

[0027] Example

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a medicinal plant Artemisia frigida planting device for ecological restoration of open-pit mine dumps, including a furrow opener 2 and a covering wheel 3 connected to the bottom of a mobile body 1, and also includes a soil screening device, which is arranged between the furrow opener 2 and the covering wheel 3. The soil screening device includes two groups of screening mechanisms, and the two groups of screening mechanisms are symmetrically arranged with the line connecting the furrow opener 2 and the covering wheel 3 as the center line. The screening mechanism includes a filter cartridge 41, a bucket 42 and a rotating assembly; the filter cartridge 41 is connected to the At the bottom of the mobile body 1, a plurality of filter holes are provided on the circumferential side wall of the filter cartridge 41, and the higher end of the filter cartridge 41 is arranged close to the furrow opener 2; the bucket 42 is arranged at the higher end of the filter cartridge 41 and is connected to the filter cartridge 41, and the bucket 42 is used to transport the soil accumulated when the furrow opener 2 forms a sowing furrow into the filter cartridge 41 when following the movement of the mobile body 1; the rotating component is connected to the outer ring surface of the filter cartridge 41, and the rotating component is used to drive the filter cartridge 41 to rotate and filter the soil and gravel in the filter cartridge 41.

[0029] In this embodiment, when planting Artemisia frigida, the soil screening device is first placed on the mobile body 1, and the mobile body 1 is a mobile chassis or a frame that can be towed and moved by a tractor or the like. When planting, the mobile body 1 drives the furrow opener 2 to move along the soil dump to dig a sowing furrow, and the excavated soil is separated to both sides of the sowing furrow by the furrow opener 2. Since the soil screening device and the stone collecting device move synchronously with the mobile body 1, the soil on both sides of the sowing furrow can be scooped up and transported to the filter cartridge 41 by the provided bucket 42. Since the filter cartridge 41 is arranged at an angle, the soil and stones entering the interior thereof can be screened while moving, and the screening During the process, the filter cartridge 41 is driven to rotate by the rotating component to continuously change the position of the sieve holes to prevent stones from clogging a certain sieve hole. As the filter cartridge 41 rotates, the soil and stones entering the filter cartridge 41 can be gradually separated, and the separated soil is screened out through the filter holes. Since the filter cartridge 41 is in a rotating state during the entire screening process, the problem of stones clogging the filter holes can be reduced. After screening, the seeds are sown into the sowing trench through the sowing tube and fertilized. Finally, the separated soil is backfilled into the sowing trench using the covering wheel 3, thereby effectively preventing the presence of stones from affecting the growth process of the Artemisia frigida seeds.

[0030] Among them, in order to facilitate the connection between the filter cartridge 41 and the mobile body 1, a connecting block 5 is provided at both ends of each filter cartridge 41. The top of the connecting block 5 is fixed to the bottom of the mobile body 1 through a suspension rod. A mounting hole is opened inside the connecting block 5. The end of the filter cartridge 41 is inserted into the mounting hole and is rotatably connected to the mounting hole through a bearing. The bucket 42 is fixed on the side wall of the connecting block 5 facing away from the filter cartridge 41 and is connected to the mounting hole. With this arrangement, the filter cartridge 41 can be rotated relative to the bucket 42 to achieve soil filtering.

[0031] Specifically, the rotating assembly includes a first driving motor 61, a transmission shaft 62 and a chain transmission mechanism; the first driving motor 61 is fixed on the top of the mobile body 1; one end of the transmission shaft 62 is connected to the output shaft of the first driving motor 61, and the other end is rotatably connected to a bearing seat fixed on the mobile body 1; the chain transmission mechanism includes a driving sprocket 63, a driven sprocket 64 and a chain 65; the driving sprocket 63 is fixed on the transmission shaft 62; the driven sprocket 64 is fixed on the outer wall of the filter cartridge 41; the chain 65 is connected between the driving sprocket 63 and the driven sprocket 64, and when the filter cartridge 41 is driven to rotate by the rotating assembly, the first driving motor 61 is used to drive the transmission shaft 62 to rotate, and the transmission shaft 62 rotates and drives the filter cartridge 41 to rotate through the transmission of the chain transmission mechanism, so that the filter cartridge 41 can rotate while moving.

[0032] Further, such as Figures 1 to 3 As shown, as an optimized implementation of the rotating assembly, the rotating assembly in this embodiment includes a first driving motor 61, two transmission shafts 62, a gear transmission mechanism and two sets of chain transmission mechanisms; the first driving motor 61 is fixed on the top of the mobile body 1; the two transmission shafts 62 are horizontally arranged on both sides of the first driving motor 61; the gear transmission mechanism includes a driving gear 66 and two driven gears 67, the driving gear 66 is set and fixed on the output shaft of the first driving motor 61, and the two driven gears 67 are respectively set and fixed on the two transmission shafts 62, and both are meshed with the driving gear 63; the chain transmission mechanism includes: a driving sprocket 63, which is set and fixed on the transmission shaft 62; a driven sprocket 64, which is set and fixed on the outer wall of the filter cartridge 41; and a chain 65, which is connected between the driving sprocket 63 and the driven sprocket 64. Through the above settings, the newly added gear transmission mechanism can reduce the number of the first driving motors 61, reduce costs, and ensure that the two filter cartridges 41 can be rotated and screened at the same time.

[0033] Specifically, Figure 1 , Figure 2 and Figure 4As shown, in order to collect the stones discharged through the filter cartridge 41 and prevent the stones from falling back into the filtered and discharged soil, a stone collecting assembly is also included, which is connected to the lower end of each filter cartridge 41 and is used to collect the stones discharged from the filter cartridge 41. The stone collecting assembly includes a collecting pipe 71, two collecting pipes 72, a discharge pipe 73 and a spiral conveying mechanism; the collecting pipe 71 is vertically arranged, and the lower end of the collecting pipe 71 is a closed end; the two collecting pipes 72 are arranged in a V shape, and the two collecting pipes 72 are arranged in a V shape. One end is connected to the lower side wall of the collecting pipe 71, and the other ends of the two collecting pipes 72 extend to the inside of the mounting holes opened in the two connecting blocks 5 respectively, and are fixed to the inner walls of the mounting holes; the discharge pipe 73 is arranged along the width direction of the mobile body 1, and the bottom of the discharge pipe 73 is connected to the top of the collecting pipe 71, and the top of the discharge pipe 73 is fixed to the bottom of the mobile body 1 through a connecting rod; the spiral conveying mechanism is arranged inside the collecting pipe 71 and the discharge pipe 73, and is used to lift the stones entering the collecting pipe 71 into the discharge pipe 73.

[0034] When the separated stones are collected by the collecting assembly, the two collecting pipes 72 are used to gather the stones separated from the filter cartridge 41 and move them into the collecting pipe 71. Through the provided screw conveyor, the second driving motor 74 is used to drive the screw shaft 75 and the spiral blades 76 to rotate to transport the stones along the vertical direction of the collecting pipe 71 until they are transported to the inside of the discharge pipe 73 and finally discharged from the two side pipe openings of the discharge pipe 73, thereby preventing the stones from falling into the screened soil.

[0035] Further, such as Figure 5 As shown, the discharge pipe 73 is provided with guide blocks 731 on the inner bottom surfaces on both sides of the spiral conveying mechanism. The guide blocks 731 have an inclined guide surface, and the lowest point of the guide surface is located at the port of the discharge pipe 73. The spiral conveying mechanism can be lifted to the discharge pipe 73 through the provided guide blocks 731, and the stones screened in the discharge pipe 73 can be guided to both sides of the discharge pipe 73 and separated out through the pipe mouth of the discharge pipe 73.

[0036] Furthermore, in another embodiment of the present invention, in order to be able to perform a secondary screening on some missed soil during the process of transporting the collected stones by the screw conveyor, a secondary screening mechanism is provided on the collecting pipe 71, and the secondary screening mechanism includes a screening pipe 81 and a screen 82. The screening pipe 81 is connected to the side wall of the collecting pipe 71 facing the covering wheel 3, the screening pipe 81 is arranged to be inclined downward, and the screen 82 is fixed in the port where the screening pipe 81 and the collecting pipe 71 are connected. As the spiral conveying mechanism lifts and transports the stones, when some missed soil moves to the screen 82, it can be discharged from the screening pipe 81 into the sowing furrow for backfilling after secondary screening by the screen 82.

[0037] Furthermore, in order to improve the secondary screening efficiency, multiple groups of secondary screening mechanisms are provided. The secondary screening mechanisms have multiple groups and are arranged in sequence along the longitudinal direction of the collecting pipe 71 .

[0038] Furthermore, in order to collect and screen as much soil as possible on both sides of the sowing furrow, the opening of the bucket 42 is trumpet-shaped, and the narrowest side of the bucket 42 is arranged close to the connecting block 5.

[0039] Furthermore, in order to be able to chop the soil as much as possible before the bucket 42 scoops up the soil on both sides of the sowing furrow and transports it to the inside of the filter cartridge 41 for easy screening, a cutting assembly is provided on the inner wall of the opening of the bucket 42, and the cutting assembly includes a rotating shaft 91 and multiple groups of cutting blades 92. The rotating shaft 91 is horizontally mounted between the inner walls of the opening of the bucket 42, and the two ends of the rotating shaft 91 are rotatably connected to the inside of the bucket 42 through bearings. Each group of cutting blades 92 is fixed on the circumferential side wall of the rotating shaft 91, and multiple groups of cutting blades 92 are arranged side by side along the axial direction of the rotating shaft 91. When the bucket 42 scoops up the soil, the friction of the soil and the mutual squeezing thrust during movement will drive the cutting blades 92 and the rotating shaft 91 to rotate, chopping the soil, which is convenient for screening by the filter cartridge 41.

[0040] In summary, the present invention can screen and remove the stones in the soil accumulated on both sides of the sowing furrow by setting a soil screening device. The soil screening device adopts a screening mechanism to screen the soil accumulated on both sides of the sowing furrow at the same time. During screening, the soil is scooped up by a set bucket and transported to the filter cartridge. The filter cartridge is driven to rotate by a set rotating component, so that the filter cartridge can move while rotating. As the filter cartridge rotates, the soil and stones entering the filter cartridge can be gradually separated, and the separated soil is screened out through the filter holes to avoid the stones clogging the filter holes. The remaining stones are collected by the stone collecting device at the tail of the filter cartridge, so that the covering wheel can conveniently backfill the soil after the stones are removed, thereby avoiding the problem that the growth process of Artemisia frigida seeds is affected by the presence of stones when backfilling the soil.

[0041] The above disclosures are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
