[0028] As Figure 1-7 shown, an embodiment of the present application provides a garbage landfill odor shielding system, including:

[0029] Multiple tracks 1, and the multiple tracks 1 are arranged in parallel at intervals in the garbage landfill; a tractor group, each tractor group includes at least four tractors 2, and the tractors 2 of each tractor group are movably arranged on two adjacent tracks 1. A guiding rod 201 is vertically arranged on each tractor 2, and a laying mechanism 3 is slidably arranged on the guiding rod 201; a covering film 4, which is connected to the laying mechanisms 3 of at least four tractors 2 through at least four corners respectively, and at least one through hole is opened on the covering film 4; a suction mechanism 5, which includes a base 501 and an air guiding pipe 503 arranged on the base 501. The air guiding pipe 503 is communicated with the air inlet of a vacuum pump 506 through an air guiding pipeline 505, and the air outlet of the vacuum pump 506 is communicated with an adsorption box 6. The base 501 is arranged at the through hole and its edge is connected to the edge of the through hole;

[0030] In this embodiment, the garbage truck dumps the garbage between the two tracks 1, and the tractor group quickly drives towards the dumped garbage and makes the covering film 4 located above the garbage (see Figure 2 ), the laying mechanism 3 descends along the guiding rod 201, driving the covering film 4 to quickly cover the garbage, reducing the diffusion of odor gas, and the air guiding pipe 503 is also driven into the garbage (see Figure 5 ). Start the vacuum pump, and the suction mechanism 5 performs suction treatment on the inside of the garbage, creating a negative pressure environment. The odor gas is fully carried out by the air guiding pipe 503 and enters the adsorption box 6 for removal without escaping. That is, in this embodiment, through covering and suction, odor shielding can be achieved, waiting for subsequent burial treatment;

[0031] The area between the tracks 1 is used to stack the garbage 8, and the width should be able to allow the garbage truck to enter and dump the garbage; Exemplarily, the tracks 1 can be erected with existing steel members such as channel steel, I-beam, and T-shaped steel; Exemplarily, several garbage partitions 101 are planned between two adjacent tracks 1, such as Figure 1 the A area, B area, and C area in, and the garbage truck dumps the garbage into the garbage partition 101, and the tractor 2 group sequentially covers and suctions the garbage 8 in each garbage partition 101;

[0032] The bottom of the tractor 2 is provided with rollers 204, which can move on the track 1. The tractor 2 is dragged by a winch or is provided with an electric drive structure and a battery by itself. Exemplarily, when using T-shaped steel as the track 1, the web of the T-shaped steel faces upward. The tractor 2 is provided with two rows of rollers 204, two in each row, and they are located on both sides of the web of the T-shaped steel. Exemplarily, the tractor 2 has a frame 203. A guide rod 201 is arranged on the frame 203. The guide rod 201 extends vertically. The laying mechanism 3 is slidably arranged on the guide rod 201. The laying mechanism 3 can be driven by mechanisms such as cylinders and screw nuts.

[0033] The covering film 4 is used to cover the garbage and maintain a negative pressure environment inside. It must not be breathable and has a certain strength. Exemplarily, a polymer material film such as a polyethylene film or a polyvinyl chloride film can be used.

[0034] The laying mechanism 3 is connected to the edge of the covering film 4 and is used to pull the covering film 4. When it descends along the guide rod 201 by itself, it drives the covering film 4 to descend. Exemplarily, in order to ensure full coverage of the garbage, at least four laying mechanisms 3 are required, and more than four have better effects. Correspondingly, at least four tractors 2 are also required.

[0035] The base 501 is used to install the suction mechanism 5 and has a structure that facilitates the air guide pipe 503 to extend into the garbage. Exemplarily, the base 501 is horizontally arranged. An air inlet is opened on the base 501. The air guide pipe 503 is vertically connected to the lower surface of the base 501 and communicates with the air inlet. The air guide pipeline is connected to the upper surface of the base 501 and communicates with the air inlet. Exemplarily, the air guide pipe 503 is provided with air guide holes only on the side wall, and the air guide holes are fish scale holes to reduce the blockage of the air guide holes by garbage, especially during the downward movement and insertion into the garbage.

[0036] The air guide pipe 503 introduces the odor gas into the adsorption box 6. The adsorption box 6 is provided with adsorption materials such as activated carbon and molecular sieve. After being treated by the adsorption materials, it is discharged into the atmosphere.

[0037] In summary, this embodiment can quickly achieve the covering and suction of the transported garbage 8, realize the rapid and effective shielding of the garbage odor, and overcome the defects of the prior art.

[0038] In another embodiment, the laying mechanism 3 includes a moving block 301 and a plug rod 302 connected to the moving block 301. The moving block 301 is slidably arranged on the guide rod 201 and is driven by a cylinder. The plug rod 302 is connected to the moving block 301 and extends in the vertical direction. The lower end of the plug rod 302 gradually decreases in size to form a tip, so as to insert into the landfill when the moving block 301 moves downward.

[0039] In this embodiment, the insertion rod 302 is used to insert into the ground of the landfill under the drive of the cylinder to fix the covering film 4. The insertion rod 302 is connected to the moving block 301 and can insert into the ground. Exemplarily, a covering film pull ring 303 is arranged on the outer side of the insertion rod 302 for connecting the covering film.

[0040] In another embodiment, a winding disc 202 is arranged on the upper part of the guiding rod 201 of each tractor 2. A pulling rope 2021 is wound around the winding disc 202, and the free end of the pulling rope 2021 is connected to the base 501.

[0041] In this embodiment, the pulling rope 2021 is wound around the winding disc 202, and the pulling rope 2021 is connected to the base 501. The pulling rope 2021 assists the covering film 4 to avoid the situation that when using a covering film 4 with insufficient strength, the covering film 4 cannot bear structures such as the base 501 and the air guiding pipe 503. Exemplarily, the winding disc 202 can be in an electric form. When the cylinder drives the moving block 301 to move downward, the winding disc 202 also pays out the line synchronously, so that when the covering film 4 covers the garbage, the air guiding pipe 503 on the base 501 enters the garbage. Exemplarily, a pulling rope pull ring 504 is arranged on the outer side of the base 501 for connecting the pulling rope.

[0042] In another embodiment, a blowing port is also opened on the base 501. The blowing air pipe 502 is connected to the lower surface of the base 501 and communicates with the blowing port. The air supply pipe is connected to the upper surface of the base 501 and communicates with the blowing port. The air supply pipe is also connected to a blower.

[0043] In this embodiment, the blowing port and the blowing air pipe 502 are used to blow air into the garbage to increase the internal gap of the garbage and promote the air guiding pipe 503 to lead out the odor gas. Exemplarily, in the initial stage of covering with the covering film 4, the suction of the suction mechanism 5 is the main, and then the blowing time is gradually increased. The ratio of the suction time to the blowing time in the initial stage of covering is 10:1, and the ratio is gradually reduced to 8:1 and 5:1 subsequently. After testing, the odor shielding effect of this method is the best. Exemplarily, the blowing air pipe 502 only has blowing holes on the side wall, and the blowing holes are fish scale holes (the openings face left or right) to reduce the blockage of the blowing holes by the garbage, especially during the process of moving downward and inserting into the garbage.

[0044] In another embodiment, a heater is arranged in the air supply pipe. In this embodiment, blowing hot air into the garbage can evaporate the liquid odor substances and lead them out by the air guiding pipe 503. It can also reduce the humidity of the garbage, delay the fermentation process and reduce the escape of odor substances.

[0045] In another embodiment, the air blowing pipe 502 is disposed at the center of the base 501, there are a plurality of air guiding pipes 503 which surround the air blowing pipe 502, and the length of the air blowing pipe 502 is longer than that of the air guiding pipe 503; in this embodiment, the air guiding pipes 503 are disposed around the air blowing pipe 502, the air blowing pipe 502 is relatively long, and blows air to the surroundings, promoting the odor gas to escape from the garbage and move upward, and then being introduced into the adsorption box 6 by the air guiding pipes 503.

[0046] In another embodiment, the lower ends of the air blowing pipe 502 and the air guiding pipe 503 are gradually reduced in size to form tips, so as to insert into the garbage when moving downward following the covering film 4, so as to achieve sufficient suction of the interior of the garbage, or air blowing and heating treatment.

[0047] In another embodiment, a partition plate 2022 is provided on the winding disc 202 to divide the winding disc 202 into two winding intervals, the pull rope 2021 is wound in one winding interval, and a power rope 2023 is wound in the other winding interval; the air guiding pipe 503 is inserted through the base 501 and is rotatably connected to the base 501, a housing 507 coaxial with the air guiding pipe is provided on the upper surface of the base 501, a torsion spring 508 is provided in the housing 507, one end of the torsion spring 508 is connected to the housing 507, and the other end is connected to the air guiding pipe 503. The free end of the power rope 2023 is wound around the outer wall of the air guiding pipe 503 above the housing 507, so as to drive the air guiding pipe 503 to rotate when the base 501 is pulled and lifted by the pull rope 2021, and store energy for the torsion spring 508; thus, when the pull rope 2021 is relaxed, the base 501 descends onto the garbage, and the power rope 2023 is also relaxed along with the pull rope 2021. Without the restraint of the pulling force of the power rope 2023, the torsion spring 508 can freely release its elastic potential energy. Therefore, the torsion spring 208 can drive the air guiding pipe 503 to rotate. When the base descends onto the garbage, the rotating air guiding pipe 503 is more likely to drill into the depth of the garbage.

[0048] The embodiment of the present application also provides a method for shielding the odor of a landfill, including: performing zoning 101 on the landfill, the zoning 101 is located between two adjacent tracks 1, and performing odor shielding on the garbage 8 in each zoning 101 by using the odor shielding system of the landfill, that is, using a tractor group to quickly drive towards the dumped garbage 8, and making the covering film 4 located above the garbage, and the laying mechanism 3 descends along the guide rod 201, driving the covering film 4 to quickly cover the garbage, reducing the diffusion of odor gas, and the air guiding pipe 503 is also driven into the garbage. The vacuum pump is started, and the suction mechanism 5 performs suction treatment on the interior of the garbage 8 to generate a negative pressure environment. The odor gas is fully brought out by the air guiding pipe 503 and enters the adsorption box 6 to be removed without escaping.

[0049] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those skilled in the art, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrated examples described herein.
