Description

Technical Field

[0001] The utility model relates to the technical field of soil environmental protection, in particular to a small-sized in-situ soil repairing device which is convenient for loading materials. Background Art

[0002] There are many pollution problems in the soil environment, especially heavy metal pollution in the soil, which has posed a great threat to soil safety. For example, heavy metal pollution in some mining areas seriously exceeds the standard, causing serious consequences. Therefore, the problem of soil pollution caused by heavy metal pollution needs to be solved urgently to restore the health of the soil as soon as possible.

[0003] There are many types of soil remediation equipment. According to the different degrees of soil pollution and the remediation process, they can be divided into various equipment such as soil leaching and remediation machines, graded soaking machines, cylindrical scrubbing machines, mud filter presses, water treatment machines, etc.

[0004] At present, most soil remediation machines are complete systems. The entire processing line is relatively long, the equipment is large, and it occupies an area, so the contaminated soil is transported to a designated remediation site, which increases the transportation cost and the cost of remediation is also relatively high.

[0005] The utility model mainly improves a small soil repair machine, and is applied on site, without transporting the soil to a fixed repair site. The current small repair machine has a relatively small body, which inevitably leads to limitations on the functions of the soil repair machine, and can only be classified and limited to certain functions. Since the main function of the repair machine needs to have the repair function, the soil loading and soil conditioner (referred to as agent) loading of the soil repair machine are restricted. The current small soil repair machine is loaded through an on-site excavator, and the agent is manually poured into the drug port by pouring the bagged soil conditioner (agent). The loading efficiency of the whole process is relatively low, the excavator cost is relatively high, and manual labor is wasted.

[0006] On this basis, the utility model provides a small in-situ soil remediation device which is convenient for loading. Utility Model Content

[0030] The following will describe the exemplary embodiments of the present utility model with reference to the drawings.

[0031] The present utility model is a small in-situ soil remediation device that facilitates loading, including an underframe 1. A control box is fixed on the underframe 1 to control subsequent electronic components. Crawler transmission devices are installed on both sides of the underframe 1. Compared with wheel type, the crawler type can better meet the site conditions on-site and is easier to walk. Since the functions of small soil remediation devices are limited, it is necessary to retain the core functions of remediation. On the underframe 1, a first soil conveyor 2 for conveying soil, a reagent feeder 3 for adding soil conditioner, and an impact mixing bin 4 for mixing soil and soil conditioner are arranged in sequence from left to right. A loading rack 6 is fixed on one side of the left end of the underframe 1. A loading rotating shaft 7 is rotatably installed on the loading rack 6. One end of the loading rotating shaft 7 is fixed with a loading housing 8. The inside of the loading housing 8 is a cavity, and a screw auger 9 is rotatably installed inside. One end of the screw auger 9 is fixed with a loading motor 10. The loading motor 10 is connected to the control box. The lower end of the loading housing 8 communicates with a loading bin 11 with an upward opening for soil loading. The other end of the loading housing 8 communicates with an unloading bin 12 with a downward opening for lifting the soil into the first soil conveyor 2. A worm gear 13 rotatably installed on the loading rack 6 is coaxially connected to the other end of the loading rotating shaft 7. The worm gear 13 meshes with a worm 14. The worm 14 is connected to a worm motor 15. The worm motor 15 is connected to the control box.

[0032] Since the small-scale soil remediation equipment is small as a whole, its loading is generally carried out in conjunction with an excavator, which increases the cost. The utility model has a loading casing 8 rotatably installed on the side of the base frame 1. When in use, the worm motor 15, the worm wheel 13, and the worm 14 are controlled to cooperate to make the loading casing 8 rotate to the ground, and the material is loaded from the loading bin 11, and enters the first soil conveyor 2 from the lower bin 12 through the spiral auger 9. When not in use, the worm motor 15 is reversed to make the loading casing 8 rotate upward and then leave the ground without affecting the overall movement. The worm wheel 13 and the worm 14 make the loading casing 8 self-locking and stable after the rotation is completed. The loading of the loading bin 11 can be loaded through a small loader, and there is no need to use a huge excavator to load the material, thereby reducing costs.

The other end of the first electric telescopic cylinder 17 is hinged on the leg frame 16, and the first electric telescopic cylinder 17 is connected to the control box. When the feeding casing 8 is used to load materials, the leg frame 16 is pushed to rotate to a vertical direction by the first electric telescopic cylinder 17 to support the ground and ensure the stability of the feeding casing 8 when it is working. When not in use, the leg frame 16 is rotated, folded and retracted by contracting the first electric telescopic cylinder 17 to reduce the space occupied by the leg frame 16.

[0034] A cylinder rod is also fixed on the loading rack 6, and a second electric telescopic cylinder 18 is hinged on the cylinder rod. The second electric telescopic cylinder 18 is connected to the control box, and a leg rod is fixed at the lower end of the loading machine casing 8. The other end of the second electric telescopic cylinder 18 is hinged on the leg rod. When the loading machine casing 8 is not in use, the loading machine casing 8 needs to be rotated and lifted off the ground. In order to ensure the stability of the loading machine casing 8 after it is lifted, the second electric telescopic cylinder 18 will telescope to support the loading machine casing 8.

The lower end of the slitting cone 24 is integrally connected with a cylindrical slitting column 25, and a gap is provided between the maximum diameter of the slitting cone 24 and the slitting column 25 and the side wall of the slitting bin 23. A plurality of slitting knives 26 evenly distributed in a circle are fixed on the inclined surface of the slitting cone 24, which are used to cut and crush the fallen soil conditioner to prevent agglomeration. A plurality of slitting piercing rods 27 evenly distributed in a circle are fixed between adjacent slitting knives 26 and on the side of the slitting column 25, which are used to pierce and crush the agglomerates of the soil conditioner falling from the gap. A slitting motor 28 is coaxially fixed to the upper end of the slitting cone 24, and the slitting motor 28 is used to control the rotation of the slitting cone 24 and the slitting column 25.
