That is, this embodiment can achieve odor shielding through covering and suction, waiting for subsequent landfill treatment; The area between the rails 1 is used to store garbage 8, and the width needs to be wide enough for garbage trucks to enter and dump the garbage; illustratively, the rails 1 can be constructed using existing steel components such as channel steel, I-beam, T-shaped steel, etc.; illustratively, several garbage partitions 101 are planned between two adjacent rails 1, such as Figure 1 In the A area, B area and C area, the garbage truck dumps the garbage into the garbage partition 101, and the tractor 2 groups cover and suck the garbage 8 in each garbage partition 101 in turn; The tractor 2 has rollers 204 at the bottom, and can travel on the track 1. The tractor 2 is dragged by a winch, or is provided with an electric drive structure and a battery. By way of example, when a T-shaped steel is used as the track 1, the web of the T-shaped steel faces upward, and the tractor 2 is provided with two rows of rollers 204, two in each row, and located on both sides of the web of the T-shaped steel. By way of example, the tractor 2 has a frame 203, and a guide rod 201 is provided on the frame 203, and the guide rod 201 extends vertically. The laying mechanism 3 is slidably provided on the guide rod 201, and the laying mechanism 3 can be driven by a cylinder, a screw nut, or other mechanisms. The covering film 4 is used to cover the garbage and maintain the internal negative pressure environment. It needs to be airtight and have a certain strength. For example, a polymer film such as a polyethylene film, a polyvinyl chloride film, etc. can be used. The laying mechanism 3 is connected to the edge of the covering film 4, and is used to pull the covering film 4, and when the laying mechanism 3 descends along the guide rod 201, it drives the covering film 4 to descend; illustratively, in order to ensure that the garbage is fully covered, at least four laying mechanisms 3 are required, and more than four are better, and the corresponding tractors 2 are also at least four; The base 501 is used to install the suction mechanism 5, and has a structure that allows the air duct 503 to be extended into the garbage; illustratively, the base 501 is arranged horizontally, and an air inlet is provided on the base 501, the air duct 503 is vertically connected to the lower surface of the base 501 and communicated with the air inlet, and the air duct is connected to the upper surface of the base 501 and communicated with the air inlet; illustratively, the air duct 503 is only provided with air inlet holes on the side wall, and the air inlet holes are fish scale holes, so as to reduce the air inlet holes being blocked by garbage, especially in the process of inserting garbage downward; The induced draft pipe 503 introduces the odorous gas into the adsorption box 6, which contains adsorption materials such as activated carbon and molecular sieves, and then discharges the odorous gas into the atmosphere after being treated by the adsorption materials; In summary, this embodiment can quickly cover and suck the incoming garbage 8, achieve rapid and effective shielding of the garbage odor, and overcome the defects of the prior art.

[0021] In another embodiment, the laying mechanism 3 includes a moving block 301 and an insertion rod 302 connected to the moving block 301, the moving block 301 is slidably arranged on the guide rod 201 and driven by a cylinder, the insertion rod 302 is connected to the moving block 301 and extends in the vertical direction, and the size of the lower end of the insertion rod 302 is gradually reduced to form a pointed end, so as to be inserted into the landfill when the moving block 301 moves downward; In this embodiment, the insertion rod 302 is used to be inserted 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 be inserted into the ground; illustratively, a covering film pull ring 303 is set on the outside of the insertion rod 302 for connecting the covering film.

The pull rope 2021 assists the covering film 4 to avoid the situation where the covering film 4 is not strong enough and cannot support the base 501, the air duct 503 and other structures. By way of example, the winding drum 202 can be electric. When the cylinder drives the moving block 301 to move downward, the winding drum 202 also releases the wire synchronously, so that when the covering film 4 covers the garbage, the air duct 503 on the base 501 enters the garbage. By way of example, a pull rope ring 504 is provided on the outside of the base 501 for connecting the pull rope.

[0023] In another embodiment, the base 501 is further provided with an air blowing port, the air blowing pipe 502 is connected to the lower surface of the base 501 and communicated with the air blowing port, the air supply duct is connected to the upper surface of the base 501 and communicated with the air blowing port, and the air supply duct is also communicated with a blower; In this embodiment, the blowing port and the blowing pipe 502 are used to blow air into the garbage to increase the internal gap of the garbage and promote the air duct 503 to draw out the odorous gas; exemplarily, in the initial stage of covering by the covering film 4, the suction of the suction mechanism 5 is mainly used, 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 then the ratio is gradually reduced to 8:1 and 5:1. After testing, this method has the best odor shielding effect; exemplarily, the blowing pipe 502 only has blowing holes on the side wall, and the blowing holes are fish scale holes (opening to the left or right), which reduces the blowing holes from being blocked by garbage, especially during the downward movement to insert the garbage.

[0024] In another embodiment, a heater is provided in the air supply duct; in this embodiment, hot air is blown into the garbage to evaporate the liquid odorous substances and lead them out through the induced draft pipe 503, and the humidity of the garbage can be reduced, the fermentation process is delayed, and the escape of odorous substances is reduced.

[0025] In another embodiment, the blowing pipe 502 is arranged at the center of the base 501, and there are multiple air ducts 503 surrounding the blowing pipe 502, and the length of the blowing pipe 502 is longer than that of the air duct 503; in this embodiment, the air duct 503 is arranged around the blowing pipe 502, the blowing pipe 502 is longer, and blows air in all directions, so as to promote the odorous gas to escape from the garbage and move upward, and then be introduced into the adsorption box 6 by the air duct 503.

[0026] In another embodiment, the lower ends of the blowing pipe 502 and the air duct 503 are gradually reduced in size to form a pointed end, so that when following the downward movement of the covering film 4, they can be inserted into the garbage to achieve sufficient suction, blowing, or heating treatment of the inside of the garbage.

[0027] In another embodiment, a partition plate 2022 is provided on the winding drum 202 to divide the winding drum 202 into two winding sections, the pull rope 2021 is wound in one of the winding sections, and the power rope 2023 is wound in the other winding section; the air duct 503 is passed through the base 501 and is rotatably connected to the base 501, and a casing 507 coaxial with the air duct is provided on the upper surface of the base 501, and a torsion spring 508 is provided in the casing 507, one end of the torsion spring 508 is connected to the casing 507, and the other end is connected to the air duct 503, The free end of the rope 2023 is wound around the outer wall of the air duct 503 above the casing 507, so as to pull the air duct 503 to rotate when the base 501 is pulled and lifted by the pull rope 2021, thereby storing energy for the torsion spring 508; in this way, when the pull rope 2021 is relaxed, the base 501 drops down onto the garbage, and the power rope 2023 is also relaxed along with the pull rope 2021. The torsion spring 508 is free from the tension constraint of the power rope 2023 and can freely release its elastic potential energy. Therefore, the torsion spring 208 can drive the air duct 503 to rotate. When the base drops down onto the garbage, the rotating air duct 503 can more easily penetrate into the deep of the garbage.
