Description

Technical Field

[0001] The present application relates to the technical field of garden construction, and in particular to contaminated soil remediation equipment for garden construction. Background Art

[0002] The soil in the garden may form lumps due to excessive plant roots, leading to nutrient loss; and with the development of science and technology and the continuous progress of industrialization, some harmful substances produced during urban construction will also pollute the soil; in order to improve the soil in the garden, the soil needs to be repaired, generally by loosening and breaking up the soil, and using soil repair liquid to remove harmful substances in the soil, providing a good foundation for the healthy growth of plants.

[0003] Currently, a Chinese patent with publication number CN206009408U discloses a soil remediation kettle, which includes a kettle body, a feed port and a discharge port provided on the kettle body, and a stirring device provided in the kettle body, the stirring device including a stirring shaft and stirring blades.

[0004] With regard to the above-mentioned related technologies, the inventors believe that in order to fully stir the soil in the current soil remediation kettle, the stirring blades need to be close to the inner wall of the kettle body, while the conventional stirring shaft and stirring blades have a limited stirring range, which limits the volume of the kettle body from being too large, easily resulting in a small amount of soil repaired in a single time and low soil remediation work efficiency. Therefore, the current soil remediation equipment still needs to be improved. Summary of the Invention

[0005] In order to increase the volume of soil remediation equipment without affecting the mixing uniformity, increase the amount of soil repaired in a single time, and improve work efficiency, this application provides contaminated soil remediation equipment for garden construction.

[0006] The contaminated soil remediation equipment for garden construction provided in this application adopts the following technical solutions:

[0007] The contaminated soil remediation equipment for garden construction includes a kettle body with a feed port on the side wall and a discharge port on the bottom. The kettle body is provided with a stirring mechanism, which includes a main stirring shaft driven by a motor and an eccentric wheel ring fixed on the main stirring shaft. A secondary stirring shaft is fixed at intervals at the bottom of the eccentric wheel ring, and a plurality of support rods are fixed at intervals between the eccentric wheel ring and the main stirring shaft. A driven stirring shaft is fixed at intervals at the bottom of the support rods.

[0008] By adopting the above technical solution, the eccentric wheel rim fixed on the main stirring shaft rotates with the main stirring shaft as the axis, which can cover a larger stirring range than the main stirring shaft rotates. In addition to the stable fixation of the eccentric wheel rim supported by the support rod, the stirring uniformity is further improved by distributing the auxiliary stirring shaft and the driven stirring shaft at intervals. Therefore, the volume of the soil remediation equipment can be increased without affecting the stirring uniformity, the amount of soil remediated in a single time can be increased, and the work efficiency can be improved.

[0009] Preferably, the stirring mechanism further comprises an outer ring connected to the outer periphery of the eccentric wheel rim via a connecting structure, and a plurality of linked stirring shafts are fixed at circumferential intervals on the bottom of the outer ring; and the plurality of outer rings can be spliced in sequence via the connecting structure.

[0010] By adopting the above technical solution, multiple outer rings can be spliced together through the connecting structure, which helps to extend the stirring space, is suitable for larger kettle bodies, and improves the remediation efficiency of contaminated soil.

[0011] Preferably, the kettle body is provided with a medicine feeding mechanism, which includes a medicine tank for placing the repair agent and a medicine feeding nozzle. The medicine tank is fixed on the top of the kettle body, and a connecting pipe connected to the medicine tank is relatively arranged in the kettle body, and the medicine feeding nozzle is installed at intervals at the bottom of the connecting pipe; the connecting pipe is provided with an abutment structure for closing the medicine feeding nozzle.

[0012] By adopting the above technical solution, the repair agent in the medicine tank enters the medicine feed nozzle through the connecting pipe and is then sprayed into the kettle body. The abutment structure can timely close the medicine feed nozzle during the rotation of the eccentric wheel rim, thereby avoiding the waste of the repair agent sprayed on the eccentric wheel rim.

[0013] Preferably, the abutment structure includes an abutment plate, a plug-in plate and an abutment ring, the abutment ring is fixed on the outer ring, the abutment plate is connected to the bottom of the connecting pipe through a sliding structure and can abut against the medicine feed nozzle, a plug-in groove is provided in the abutment ring, the plug-in plate is fixed to the bottom of the abutment plate and plugged into the plug-in groove; when the eccentric wheel ring is farther away from the main stirring shaft and closer to the medicine feed nozzle, the abutment plate slides and abuts against the bottom of the medicine feed nozzle.

[0014] By adopting the above technical solution, when the eccentric wheel rim is farther away from the main stirring shaft and closer to the medicine feed nozzle, the abutment ring drives the plug plate to slide toward the connecting pipe until the abutment plate and the sealing plate move to abut the bottom of the medicine feed nozzle; at the same time, the eccentric wheel rim is staggered from the corresponding medicine feed nozzle at the closer end of the main stirring shaft, and the corresponding abutment plate slides in the direction away from the connecting pipe under the drive of the abutment ring, and the medicine feed nozzle is exposed to spray the repair agent, thereby making the spraying of the repair agent in the kettle more uniform and reducing the waste of spraying on the eccentric wheel rim.

[0015] Preferably, the sliding structure includes a lap plate relatively fixed on the abutment plate and a matching plate relatively fixed on both sides of the bottom of the connecting pipe. The matching plate matches the shape of the lap plate. The lap plate overlaps the corresponding matching plate and can slide along the matching plate.

[0016] By adopting the above technical solution, the overlapping plate slides along the matching plate, keeping the abutting plate connected to the connecting pipe and guiding the sliding process of the abutting plate.

[0017] Preferably, a sealing plate made of rubber material is fixed on the abutting plate and located between the opposite overlapping plates.

[0018] By adopting the above technical solution, the sealing plate has a better sealing effect on the medicine feeding nozzle.

[0019] Preferably, the plug-in board is in an arc shape that matches the shape of the plug-in slot.

[0020] Preferably, the connecting structure includes a connecting block fixed to the inner side wall of the outer ring and a connecting groove opened on the eccentric wheel rim, a protrusion is fixed on the connecting block, and a card slot for positioning the protrusion is opened on the connecting groove; a positioning block is connected to the connecting groove through a spring, and the top of the positioning block slides along the card slot; the connecting block is inserted into the connecting groove, the protrusion is positioned in the card slot, and the top of the positioning block abuts against the protrusion.

[0021] By adopting the above technical solution, the positioning block abuts against the convex point, so that the convex point is stably positioned in the slot, thereby improving the stability of the outer ring when installed on the eccentric wheel rim.

[0022] Preferably, the outer ring is formed by splicing opposite half rings; both ends of one half ring are extended to form extension blocks, and both ends of the other half ring are extended to form support blocks overlapping with the extension blocks, and magnets that attract each other are fixed on the support blocks and the extension blocks.

[0023] By adopting the above technical solution, the relative half rings are spliced to the outer ring, making it easier to install the outer ring on the eccentric wheel rim and to splice multiple outer rings; the extension block and the support block are attracted by magnets, with a simple structure and convenient operation.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The eccentric wheel fixed on the main stirring shaft rotates around the main stirring shaft, covering a wider stirring range than the main stirring shaft's self-rotation. In addition to the stable fixation of the eccentric wheel supported by the support rod, the spacing of the auxiliary stirring shaft and the driven stirring shaft further improves the stirring uniformity. This allows the volume of the soil remediation equipment to be increased without affecting the stirring uniformity, thereby increasing the amount of soil remediated in a single operation and improving work efficiency.

[0026] 2. When the eccentric wheel is farther away from the main stirring shaft and closer to the medicine feed nozzle, the abutting ring drives the plug plate to slide toward the connecting pipe until the abutting plate and the sealing plate move to abut under the medicine feed nozzle; at the same time, the eccentric wheel is staggered from the corresponding medicine feed nozzle at the closer end of the main stirring shaft, and the corresponding abutting plate slides away from the connecting pipe under the drive of the abutting ring, exposing the medicine feed nozzle to spray the repair agent, thereby making the spraying of the repair agent in the kettle more uniform and reducing the waste of spraying on the eccentric wheel;

[0027] 3. The connection structure enables the splicing of multiple outer rings, which helps to extend the stirring space, is suitable for larger kettles, and improves the efficiency of remediation of contaminated soil. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present application is further described in detail below with reference to the accompanying drawings.

[0036] The present application embodiment discloses a contaminated soil remediation device for garden construction, referring to Figure 1 、 2 It includes a kettle body 1 with a feed port 11 on the side wall and a discharge port 12 on the bottom. A stirring mechanism 2 and a medicine feeding mechanism 4 are provided in the kettle body 1. The medicine feeding mechanism 4 includes a medicine tank 41 fixed to one side of the top of the kettle body 1 for placing a repair agent. After the repair agent is added to the soil to be repaired in the kettle body 1, the stirring mechanism 2 is used to stir and mix the soil to repair the soil and remove harmful substances in the soil, providing a good foundation for the healthy growth of plants.

[0037] Reference Figure 1 、 2 The stirring mechanism 2 includes a main stirring shaft 21 driven by a motor 15 fixed to the upper middle part of the kettle body 1 and an eccentric wheel 22 fixed on the main stirring shaft 21. A secondary stirring shaft 221 is fixed at intervals at the bottom of the eccentric wheel 22. A plurality of support rods 3 are fixed at intervals between the eccentric wheel 22 and the main stirring shaft 21. A driven stirring shaft 31 is fixed at intervals at the bottom of the support rod 3. The main stirring shaft 21 stirs and drives the eccentric wheel 22 to rotate at the same time. Compared with the conventional stirring setting with a single main stirring shaft 21, the stirring range is effectively expanded and the stirring volume is increased, thereby increasing the amount of contaminated soil remediation in a single time and improving the remediation efficiency.

[0038] Reference Figure 2 、 3 The stirring mechanism 2 also includes an outer ring 23 connected to the outer periphery of the eccentric wheel 22. A number of linked stirring shafts 233 are fixed at circumferential intervals on the bottom of the outer ring 23. By adding outer rings 23, the stirring range of the linked stirring shaft 233 can be extended, and the linked stirring shaft 233 and the auxiliary stirring shaft 221 are arranged alternately in the circumferential direction to cover a larger stirring surface; the driven stirring shaft 31 is arranged to avoid the stirring range of the main stirring shaft 21, and the structure is more reasonable.

[0039] Reference Figure 2 、 4 The outer ring 23 is formed by splicing opposite half rings; both ends of one half ring are extended to form extension blocks 231, and both ends of the other half ring are extended to form support blocks 232 overlapping with the extension blocks 231, and magnets 5 that attract each other are fixed on the support blocks 232 and the extension blocks 231. The outer ring 23 is spliced and formed by the two half rings, making it easier to install the outer ring 23 on the eccentric wheel 22 and reducing the difficulty of operation.

[0040] Reference Figure 1 、 5The outer ring 23 is connected to the eccentric wheel 22 through the connecting structure 6, and the outer ring 23 can be spliced in sequence through the connecting structure 6, thereby realizing the splicing of multiple outer rings 23, which helps to extend the stirring space, is suitable for a larger kettle body 1, and improves the efficiency of remediation of contaminated soil.

[0041] Reference Figure 5 The connecting structure 6 includes a connecting block 61 fixed to the inner side wall of the outer ring 23 and a connecting groove 62 opened on the outer side wall of the eccentric wheel 22, and the connecting block 61 is inserted into the connecting groove 62; a protrusion 611 is fixed above the end of the connecting block 61, and a slot 621 for positioning the protrusion 611 is opened above the connecting groove 62; a positioning block 8 is connected to the connecting groove 62 through a spring 7, and the top of the positioning block 8 slides along the slot 621. When the protrusion 611 is positioned in the slot 621, the top of the positioning block 8 abuts against the protrusion 611 under the elastic force of the spring 7, and the top of the positioning block 8 and the protrusion 611 are stably positioned in the slot 621.

[0042] Reference Figure 1 、 2 , the kettle body 1 is relatively provided with a communicating pipe 10 connected to the medicine tank 41, referring to Figure 1 、 6 The medicine feeding mechanism 4 also includes a medicine feeding nozzle 42, which is installed at intervals at the bottom of the connecting pipe 10. The repair agent in the medicine tank 41 enters the medicine feeding nozzle 42 through the connecting pipe 10 and is then sprayed on the soil in the kettle body 1.

[0043] Reference Figure 2 、 6 An abutment structure 9 for closing the medicine feed nozzle 42 is provided on the connecting pipe 10. When the eccentric wheel 22 rotates from the far end of the main stirring shaft 21 to a position close to the medicine feed nozzle 42, the medicine feed nozzle 42 is closed by the abutment structure 9, thereby reducing the waste of the repair agent sprayed directly on the eccentric wheel 22.

[0044] Reference Figure 2 、 6 The abutment structure 9 includes an abutment plate 91, which is connected to the bottom of the connecting pipe 10 through a sliding structure 13 and can abut against the medicine feeding nozzle 42; the sliding structure 13 includes a lap plate 131 relatively fixed on the abutment plate 91 and a matching plate 132 relatively fixed on both sides of the bottom of the connecting pipe 10, the lap plate 131 is an "L" shape extending upward and bending, and the bent ends of the relative lap plates 131 extend in directions away from each other, and the matching plate 132 matches the shape of the lap plate 131. The lap plate 131 is overlapped with the corresponding matching plate 132 and can slide along the matching plate 132; a rubber sealing plate 14 is fixed on the abutment plate 91 and between the relative lap plates 131. The sealing plate 14 can abut and seal under the medicine feeding nozzle 42 to prevent the medicine feeding nozzle 42 from spraying the repair agent.

[0045] Reference Figure 2 、 6 The abutment structure 9 also includes a plug-in plate 92 and an abutment ring 93. The abutment ring 93 is fixed on the outer ring 23. A plug-in groove 931 is provided in the abutment ring 93. The plug-in plate 92 is fixed to the bottom of the abutment plate 91 and plugged into the plug-in groove 931. The plug-in plate 92 is in an arc shape that matches the shape of the plug-in groove 931. When the eccentric wheel 22 is farther away from the main stirring shaft 21 and closer to the medicine feeding nozzle 42, the abutment ring 93 drives the plug-in plate 92 to slide toward the direction close to the connecting pipe 10 until the abutment plate 9 1 and the sealing plate 14 move to abut against the bottom of the medicine feed nozzle 42; at the same time, the eccentric wheel 22 is staggered from the corresponding medicine feed nozzle 42 at the closer end of the main stirring shaft 21, and the corresponding abutment plate 91 slides in the direction away from the connecting pipe 10 under the drive of the abutment ring 93, and the medicine feed nozzle 42 is exposed to spray the repair agent. Therefore, the spraying of the repair agent is more uniform by alternately spraying the medicine feed nozzle 42 on the relative connecting pipe 10, and the waste of the repair agent sprayed on the eccentric wheel 22 can be reduced.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
