Description

Technical Field

[0001] The present invention relates to the technical field of soil remediation, and particularly relates to a rhizosphere soil remediation device based on a microbial flora. Background Art

[0002] In order to increase the yield and income of crops, a large amount of chemical fertilizers and pesticides are needed. For example, in orchards, chemical fertilizers are often applied to the rhizosphere of fruit trees, resulting in serious over-standard of organic matter and other substances in the rhizosphere soil, serious pollution of the rhizosphere soil, and difficulty for the rhizosphere soil to be rapidly repaired by relying on the natural environment, leading to the accumulation of pollution, and then problems such as serious soil compaction and crop growth failure occur. A microbial flora is a synthetic flora that combines microorganisms with complementary functions (such as phosphorus solubilization, nitrogen fixation, salt resistance, etc.) to build a multi-strain synergy. These flora achieve stable metabolism through cross-feeding and quorum sensing, forming a microenvironment similar to a natural ecosystem, which can effectively improve the physical and chemical properties of the soil, inhibit soil-borne diseases, and reduce fertilizer dependence and environmental pollution. The existing methods for using microbial flora to repair and improve plant rhizosphere soil usually involve manually turning the soil near the rhizosphere, then putting microbial flora capsules or carriers in the soil around the fruit trees, and finally covering the soil with microbial fertilizer to prevent the microbial fertilizer from flowing away. This method of manually putting microbial flora capsules or carriers has problems such as high labor intensity, low operation efficiency, and high labor costs. Summary of the Invention

[0003] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the present invention is: to provide a rhizosphere soil remediation device based on a microbial flora to solve the problems of high labor intensity and low operation efficiency in the prior art when using manual soil turning and putting microbial flora capsules or carriers.

[0004] To solve the above technical problem, a technical solution adopted by the present invention is: a rhizosphere soil remediation device based on a microbial flora, including a traveling part, a moving contact part arranged on the traveling part, and a discharging mechanism arranged on the moving contact part. The moving contact part is used to adjust the distance between the discharging mechanism and the tree trunk according to the size of the tree trunk diameter. The moving contact part includes a horizontally arranged cross plate, a V-shaped block horizontally arranged at one end of the cross plate, a sliding rod horizontally arranged along the length direction of the cross plate, a driving member one for driving the sliding rod to slide along the length direction of the cross plate, and a sliding member one that is in gear transmission connection with the sliding rod and is slidably connected to the cross plate. The discharging mechanism is fixedly connected to the sliding member one and is used to apply the microbial flora to the rhizosphere soil of the tree trunk.

[0005] Further, an installation groove is recessed on the upper surface of the cross plate. The installation groove is arranged along the length direction of the cross plate. The first driving member is arranged in the installation groove to drive the sliding rod to horizontally slide along the symmetry center plane of the V-shaped block. The sliding rod is slidably connected to the cross plate.

[0006] Further, a first gear is rotatably arranged in the cross plate. The axis of the first gear is vertically arranged. The sliding rod is located on one side of the first gear. A first rack meshing with the first gear is fixedly connected to the sliding rod. The first sliding member includes a second rack meshing with the first rack on the other side of the first gear. The discharging mechanism is fixedly connected to the second rack.

[0007] Further, the second rack is a T-shaped plate. A first T-shaped groove cooperating with the second rack is arranged on the cross plate along the length direction of the cross plate. One end of the second rack far from the gear extends out of the cross plate. The discharging mechanism is fixedly connected to the end of the second rack far from the gear.

[0008] Further, the discharging mechanism includes an upper plate horizontally arranged and fixedly connected to the second rack, a drilling component arranged on the upper plate, a second driving member driving the drilling component to drill downward into the soil, and a material box arranged on the upper plate. The drilling component includes a mounting plate horizontally arranged below the upper plate, a drill rod vertically arranged, and a third driving member arranged on the mounting plate for driving the drill rod to rotate. A discharging channel is arranged inside the drill rod. The material box is communicated with the discharging channel.

[0009] Further, the second driving member includes an electric push rod two fixedly connected to the upper plate. The output shaft of the electric push rod two is vertically downward. The mounting plate is horizontally arranged and fixedly connected to the output shaft of the electric push rod two. The third driving member includes a driving motor fixedly connected to the mounting plate. A driving gear is fixedly connected to the output shaft of the driving motor. The upper end of the drill rod passes upward through the mounting plate and is rotatably connected to the mounting plate. A driven gear meshing with the driving gear is fixedly connected to the drill rod. The discharging channel is coaxially arranged with the drill rod. The upper end of the discharging channel penetrates upward through the drill rod. A discharging port communicating the lower inner cavity of the discharging channel with the external space of the drill rod is horizontally arranged on the lower side wall of the drill rod. The upper end of the discharging channel is coaxially rotatably connected to a rotary joint. The rotary joint is fixedly connected to the mounting plate through a fixing bracket. The material box is communicated with the rotary joint through a first hose.

[0010] Further, an arc-shaped groove coaxial with the drill rod is arranged inside the lower side wall of the drill rod. The arc-shaped groove is cross-connected with the discharging port. An arc-shaped plate is slidably connected in the arc-shaped groove. A baffle is fixedly connected perpendicular to the outer wall of the arc-shaped plate. The baffle extends out of the drill rod along the radial direction of the drill rod.

[0011] When the drill pipe rotates forward to drill downward, the soil around the drill pipe generates a thrust on the baffle, causing the arc-shaped plate to slide and block the discharge port. When the drill pipe rotates reversely and withdraws upward from the drill hole, the soil around the drill pipe generates a reverse thrust on the baffle, causing the arc-shaped plate to slide and open the discharge port.

[0012] Further, the first driving member includes an electric push rod one with an axis arranged along the length direction of the cross plate.

[0013] Further, a contact sensor is arranged at one end of the sliding rod close to the V-shaped block. When the sliding rod contacts the tree trunk, the contact sensor controls the electric push rod one to stop driving the sliding rod to slide through the controller.

[0014] Further, the upper part of the drill pipe is set as a smooth rod, and spiral fins are arranged on the outer wall of the lower end of the drill pipe. This enables the soil turned by the drill head to be retained in the drill hole for convenient backfilling of the drill hole.

[0015] In the above solution, an electromagnetic valve can be arranged on the outer wall of the bottom of the material box to control the on / off of the material discharge channel of the material box. By controlling the electromagnetic valve, the length of the material discharge time of the microbial flora in the material box can be controlled to control the amount of the released microbial flora. In this solution, the microbial flora can be first placed in a capsule or other containers or carriers with a slow-release function, and then the capsule or carrier loaded with the microbial flora is stored in the material box and discharged into the drill hole after drilling.

[0016] In this solution, by operating or driving the traveling part, the V-shaped block is aligned with the tree trunk and the two inclined surfaces of the V-shaped block contact the tree trunk. At this time, there is a certain distance between the tree trunk and the outer end of the sliding rod. The larger the diameter of the tree trunk, the larger the distance between the tree trunk and the sliding rod. The smaller the diameter of the tree trunk, the smaller the distance between the tree trunk and the sliding rod. Operate the electric push rod one to push the sliding rod to slide towards the tree trunk until it contacts the tree trunk. The contact sensor transmits a stop signal to the controller, and the electric push rod one stops operating. When the sliding rod slides towards the tree trunk, the first rack that moves synchronously with the sliding rod drives the first gear to rotate. The rotation of the first gear causes the second rack meshing with the first gear to drive the upper plate to slide away from the tree trunk. The larger the tree trunk, the larger the distance the upper plate slides away from the tree trunk, resulting in the discharge mechanism being farther away from the tree trunk. Similarly, the smaller the tree trunk, the closer the discharge mechanism is to the tree trunk, and it can just drill holes and release the microbial flora at the rhizosphere of the corresponding tree trunk.

[0017] When drilling is required after the upper plate moves, the driving motor runs forward to drive the drill rod to rotate and the electric push rod two operates to push the mounting plate downward. The drill rod drills downward at the rhizosphere of the tree trunk. At this time, the soil around the drill rod generates a thrust in the first direction on the baffle, causing the arc plate to slide and block the discharge port, so that the soil cannot enter the discharge channel. When the drilling reaches the preset depth, stop operating the electric push rod two, control the output shaft of the electric push rod two to contract to make the mounting plate slide upward. At the same time, run the driving motor in reverse and control the solenoid valve on the material box to open the blanking channel of the material box for a certain period of time and then close the blanking channel of the material box. A certain amount of capsules or other carriers loaded with microbial flora in the material box fall to the bottom of the discharge channel in the drill rod through pipeline one. When the driving motor drives the drill rod to rotate in reverse, the soil in the drilling hole generates a thrust in the second direction on the baffle, causing the arc plate to slide and the discharge port to conduct. The drill rod in reverse rotation throws the capsules or other carriers of the microbial flora in the lower inner cavity of the discharge channel into the drilling hole. When the drill rod rotates in reverse and gradually moves upward, the spiral blades at the lower part of the drill rod push the soil in the drilling hole downward to cover the capsules of the microbial flora or other microbial flora carriers.

[0018] Compared with the prior art of manually turning the soil and putting the microbial flora, the present solution has at least the following

[0019] Beneficial effects:

[0020] In this solution, the driving motor drives the drill rod to drill downward to loosen the soil and add microbial flora to the rhizosphere soil, effectively reducing the labor intensity and improving the labor efficiency. This solution can automatically adjust the distance between the discharge mechanism and the tree trunk according to the size of the tree trunk to drill and put the microbial flora more accurately at the rhizosphere, and automatically cover the microbial carrier with soil after applying the microbial flora to the rhizosphere soil.

[0038] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present application.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0040] Such as Figures 1-6As shown in the figure, a rhizosphere soil remediation device based on microbial flora in this embodiment includes a traveling part, a moving contact part disposed on the traveling part, and a discharging mechanism disposed on the moving contact part. The moving contact part is used to adjust the distance between the discharging mechanism and the tree trunk according to the size of the tree trunk diameter. The discharging mechanism is used to release the microbial flora into the rhizosphere soil of the corresponding plant to repair the soil near the rhizosphere of the object to be repaired. When the object to be repaired is a plant with a larger tree trunk diameter, the location where the microbial flora is released should be appropriately far from the tree trunk. Similarly, when the object to be repaired is a plant with a smaller tree trunk diameter, the location where the microbial flora is released should be appropriately close to the tree trunk, so that the microbial flora can be released into the rhizosphere soil adapted to the plant through the discharging mechanism.

[0041] In this embodiment, the traveling part includes, but is not limited to, a moving chassis, a frame with rollers and other movable components that can be manually controlled or driven. The traveling part is used to carry other components of the device to facilitate movement or control of other components.

[0042] Such as Figure 1 , Figure 2As shown, the moving contact part includes a horizontal cross plate 10, a V-shaped block 20 horizontally arranged at one end of the cross plate 10, a sliding rod 30 horizontally arranged along the length direction of the cross plate 10, a first driving part for driving the sliding rod 30 to slide along the length direction of the cross plate 10, and a first sliding part that is in gear transmission connection with the sliding rod 30 and is slidably connected to the cross plate 10.

The V-shaped block 20 is horizontally arranged such that the central symmetry plane of the V-shaped block 20 is vertically arranged and coplanar with the vertical central plane of the cross plate 10. The V-shaped block 20 is used to measure the diameter of the tree trunk. When the diameter of the tree trunk is larger, when the tree trunk contacts both inner inclined surfaces of the V-shaped block 20, the tree trunk is farther away from the intersection line of the two inclined surfaces of the V-shaped block 20. An installation groove 101 is recessed on the upper surface of the cross plate 10. The installation groove 101 is arranged along the length direction of the cross plate 10. The first driving part is a first electric push rod 40. The first electric push rod 40 is arranged in the installation groove 101 along the length direction of the cross plate 10 and is located on the central symmetry plane of the V-shaped block 20. The first electric push rod 40 is externally connected to a power supply and a controller for controlling the operating state of the first electric push rod 40. The sliding rod 30 is also arranged in the installation groove 101 and is coaxially arranged with the first electric push rod 40. One end of the sliding rod 30 is fixedly connected to the output shaft of the point retreat post. The other end of the sliding rod 30 extends out of the installation groove 101 along the length direction of the cross plate 10 in the direction close to the V-shaped block 20. The sliding rod 30 passes through the cross plate 10 and is slidably connected to the cross plate 10. Under the push of the electric push rod, the sliding rod 30 slides horizontally along the central symmetry plane of the V-shaped block 20 to approach or move away from the tree trunk. A contact sensor is arranged at the end of the sliding rod 30 close to the V-shaped block 20. When the sliding rod 30 contacts the tree trunk, the contact sensor controls the first electric push rod 40 to stop driving the sliding rod 30 to slide through the controller.

[0043] Combined with Figure 1 、 Figure 2 As shown, a first gear 50 is arranged in the cross plate 10. The axis of the first gear 50 is vertically arranged. The first gear 50 is rotatably connected to the cross plate 10. The sliding rod 30 is located on one side of the first gear 50. A first rack 301 that meshes with the first gear 50 is fixedly connected to the side of the sliding rod 30 close to the gear. The first sliding part includes a second rack 51 that is located on the other side of the first gear 50 and meshes with the first rack 301. The second rack 51 is located on the side of the first gear 50 far from the first rack 301. The second rack 51 is arranged in parallel with the first rack 301. The material discharging mechanism is fixedly connected to the second rack 51 for applying microorganisms to the rhizosphere soil of the tree trunk. The second rack 51 is a T-shaped plate. A T-shaped groove 52 is arranged on the cross plate 10 along the length direction of the cross plate 10 for cooperating with the second rack 51. The end of the second rack 51 far from the gear extends out of the cross plate 10. The material discharging mechanism is fixedly connected to the end of the second rack 51 far from the gear.

[0044] The blanking mechanism includes an upper plate 60 horizontally arranged and fixedly connected to the second rack 51, a drilling assembly arranged on the upper plate 60, a second driving member for driving the drilling assembly to drill downward into the soil, and a material box 61 arranged on the upper plate 60 for containing microbial flora. The drilling assembly includes a mounting plate 62 horizontally arranged below the upper plate 60, a drill rod 63 vertically arranged, and a third driving member arranged on the mounting plate 62 for driving the drill rod 63 to rotate. Please refer to Figure 3As shown, the second driving member includes an electric push rod two 65 fixedly arranged on the upper surface of the upper plate 60. The electric push rod two 65 is externally connected to a power supply and a controller for controlling the operating state of the electric push rod two 65. The output shaft of the electric push rod two 65 is arranged vertically downward. The output shaft of the electric push rod two 65 passes through the upper plate 60 downward and is slidably connected to the upper plate 60. The mounting plate 62 is horizontally arranged below the upper plate 60 and is fixedly connected to the shaft end of the output shaft of the electric push rod two 65. A sliding column 621 is vertically arranged on the lower surface of the mounting plate 62. The upper end of the sliding column 621 is fixedly connected to the upper plate 60. A sliding hole for sliding connection with the sliding column 621 is arranged on the mounting plate 62. The third driving member includes a driving motor 64 fixedly connected to the mounting plate 62. The driving motor 64 is externally connected to a power supply and a controller for controlling the operating state of the driving motor 64. The driving motor 64 is fixedly connected to the upper surface of the mounting plate 62. The output shaft of the driving motor 64 is arranged vertically and passes through the mounting plate 62 downward. A driving gear 641 is fixedly connected to the output shaft of the driving motor 64 below the mounting plate 62. A driven gear 632 meshing with the driving gear 641 is fixedly connected to the drill rod 63. The upper part of the drill rod 63 is a smooth rod. A spiral blade 634 for turning the soil is arranged on the outer wall of the lower end of the drill rod 63. The upper end of the drill rod 63 passes through the mounting plate 62 upward and is rotatably connected to the mounting plate 62 by arranging a two-way thrust bearing. A discharge channel 631 is arranged inside the drill rod 63. The discharge channel 631 is coaxially arranged with the drill rod 63. The upper end of the discharge channel 631 penetrates the drill rod 63 upward. The lower end of the discharge channel 631 is a blind end. A discharge port 633 for communicating the lower inner cavity of the discharge channel 631 with the external space of the drill rod 63 is horizontally arranged on the lower side wall of the drill rod 63. The upper end of the discharge channel 631 is coaxially rotatably connected to a rotary joint 70. The rotary joint 70 is a prior art and will not be elaborated here. The rotary joint 70 is fixedly connected to the mounting plate 62 through a fixing bracket 71. The material box 61 is communicated with the rotary joint 70 through a hose one 72 to introduce the microbial flora into the discharge channel 631 inside the drill rod 63 through the hose. In this embodiment, an electromagnetic valve can be arranged on the outer wall of the bottom of the material box 61 to control the on / off of the discharge channel of the material box 61. By controlling the electromagnetic valve, the length of the discharge time of the microbial flora in the material box 61 can be controlled to control the amount of the released microbial flora. The microbial flora can be first placed in a capsule or other containers or carriers with a slow-release function, and then the capsule or carrier loaded with the microbial flora is stored in the material box 61 and discharged into the drill hole after drilling.

[0045] Combined with Figure 4As shown, an arc T-shaped groove 52 coaxial with the drill rod 63 is provided in the lower side wall of the drill rod 63, and the arc T-shaped groove 52 is cross-connected with the discharge port 633. An arc plate 81 is slidably connected in the arc T-shaped groove 52, and a baffle 810 is fixedly connected to the outer wall perpendicular to the arc plate 81, and the baffle 810 extends out of the drill rod 63 along the radial direction of the drill rod 63.

[0046] In the above scheme, if Figure 6 As shown, by manipulating or driving the walking part, the V-shaped block 20 is aligned with the tree trunk 90 and the two inclined surfaces of the V-shaped block 20 contact the tree trunk 90. At this time, the tree trunk 90 is at a certain distance from the outer end of the slide bar 30. When the diameter of the tree trunk 90 is larger, the distance between the tree trunk 90 and the slide bar 30 is larger. When the diameter of the tree trunk 90 is smaller, the distance between the tree trunk 90 and the slide bar 30 is smaller. The electric push rod 40 is operated to push the slide bar 30 to slide toward the direction close to the tree trunk 90 until it contacts the tree trunk 90. The contact sensor transmits a stop signal to the controller, and the electric push rod 40 stops running. When the slide bar 30 slides toward the direction approaching the trunk 90, the rack 1 301 moving synchronously with the slide bar 30 pushes the gear 1 50 to rotate. The rotation of the gear 1 50 causes the rack 2 51 meshing with the gear 1 50 to drive the upper plate 60 to slide away from the trunk 90. The larger the trunk 90, the greater the distance the upper plate 60 slides away from the trunk 90, resulting in the discharge mechanism being farther away from the trunk 90. Similarly, the smaller the trunk 90, the closer the discharge mechanism is to the trunk 90, so that it can drill holes at the root zone of the corresponding trunk 90 and release the microbial flora.

[0047] When drilling is needed after the upper plate 60 moves, the driving motor 64 is operated in the forward direction to drive the drill rod 63 to rotate and the electric push rod 2 65 is operated to push the mounting plate 62 downward, and the drill rod 63 drills a hole downward at the root of the tree trunk 90. At this time, the soil around the drill rod 63 generates a thrust in the first direction on the baffle 810, so that the arc plate 81 slides to block the discharge port 633, and the soil cannot enter the discharge channel 631. When the drilling reaches the preset depth, the electric push rod 2 65 is stopped, and the output shaft of the electric push rod 2 65 is controlled to shrink to make the mounting plate 62 slide upward. At the same time, the driving motor 64 is operated in the reverse direction and the solenoid valve on the material box 61 is controlled to open the material drop channel of the material box 61 for a certain period of time and then close it. The material box 61 has a material drop channel, and a certain amount of capsules or other carriers loaded with microbial flora in the material box 61 falls into the bottom of the discharge channel 631 in the drill rod 63 through a pipe. When the driving motor 64 drives the drill rod 63 to rotate in the opposite direction, the soil in the borehole generates a thrust in the second direction on the baffle 810, so that the arc plate 81 slides and the discharge port 633 is opened. The reversely rotating drill rod 63 throws the capsules or other carriers of the microbial flora in the lower inner cavity of the discharge channel 631 into the borehole. When the borehole rotates in the opposite direction and gradually moves upward, the spiral sheet 634 at the bottom of the drill rod 63 pushes the soil in the borehole downward to cover the capsules or other microbial flora carriers.

[0048] The above are only embodiments of the present invention, and common knowledge such as specific structures and characteristics known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
