DETAILED DESCRIPTION

[0017] In order to have a further understanding of the purpose, structure, features and functions of the present invention, Figure 1-3 The details are described below with examples.

[0018] In this case, a chemical spray pipe 710 for spraying chemical liquid and a first branch pipe 620 for collecting internal exhaust gas are installed inside the shell 200. At the same time, a gas collection hood 300 for collecting exhaust gas at the feed inlet 220 is also provided outside the shell 200. The gas collection hood 300 can effectively cover the exhaust gas area involved in the feeding process of the soil through a funnel-shaped structure design, and merges with the first branch pipe 620 through a second branch pipe 630 to be connected to the fan 600. When the fan 600 is started, exhaust gas can be collected from both the soil outside and the soil inside the chamber 210. Specifically,

[0019] The intelligent dosing and mixing machine includes a housing 200, a chamber 210 formed in the housing 200, a spiral blade 400 installed in the chamber 210 along its length, one end of the spiral blade 400 is connected to the housing via a reduction motor 430, and the chamber 210 is formed with a feed port 220 at one end and a soil discharge port 230 at the lower portion of the other end.

[0020] Here, those skilled in the art will understand that the spiral blade 400 has a connecting rod 410 located at the central axis. The head end of the connecting rod 410 is connected to the reduction motor 430 through the gear box 420. The tail end of the connecting rod 410 is rotatably connected to the housing 200. The spiral blade 400 is driven by the reduction motor 430 to rotate. When the soil enters the chamber 210 through the feed port 220, the soil is continuously turned forward by the turning and stirring of the spiral blade 400, and is finally discharged from the soil discharge port 230 at the bottom. In order to repair the soil and collect waste gas (generally harmful gases raised by the soil during the turning process) during the turning process, the first branch pipe 620 and the second branch pipe 630 are used to collect the waste gas, and the chemical spray pipe 710 is used to spray the chemical.

[0021] The first branch pipe 620 is located in the chamber and installed above the spiral blade 400. The first branch pipe 620 extends along the length of the chamber and has a plurality of air outlets 621 evenly distributed below.

[0022] The second branch pipe 630 is located outside the housing 200, with one end extending to directly above the feed port 220 and forming a gas collecting cover 300 for covering the space above the feed port 220. The other end is connected to the first branch pipe 620 and connected to the fan 600 after the merging. The air outlet of the fan 600 is connected to the activated carbon box 800.

[0023] Here, those skilled in the art will understand that both the first branch pipe 620 and the second branch pipe 630 are used to collect exhaust gas. The difference is that the first branch pipe 620 absorbs the gas generated by the mixture of soil and reagents inside the chamber 210, while the second branch pipe 630 collects the exhaust gas generated when the soil is dumped through the gas collection hood 300, and both are driven by the fan 600. Specifically, a spray area 211 is formed above the chamber 210. The spray area 211 reserves the internal space required for installing the first branch pipe 620. The extension length of the first branch pipe 620 is adapted to the axial length of the spiral blade 400, that is, it runs through the entire internal length of the chamber 210. This can effectively ensure that the air outlet 621 can be arranged in each area of ​​the chamber 210 to improve the gas collection effect. The second branch pipe 630 connected thereto is arranged outside the housing 200, and the end is covered by the gas collection hood 300 to cover the area above the feed inlet 220, thereby achieving the collection of exhaust gas during the discharge process. In practice, an inclined feed hopper 500 is installed at the feed port 220, and the gas collecting hood 300 is arranged just above the feed hopper 500 and the feed port 220, and covers the space area above the gas collecting hood 300 (i.e. Figure 1 The gas collecting area 310 in the chamber 210 is arranged in such a position that the layout of the position can effectively ensure that the gas does not leak out during the dumping process of the soil, thereby improving the utilization efficiency. It is worth mentioning that the first branch pipe 620 and the second branch pipe 630 are both connected to the fan 600 through the air duct 610. This arrangement allows the fan 600 to collect the exhaust gas simultaneously when it is started, whether it is the process of discharging the material or the process of stirring in the chamber 210. In this way, not only the gas collection efficiency is improved, but also the possibility of gas leakage in any link is guaranteed, thereby ensuring the ultimate use effect.

[0024] An activated carbon box 800 is connected to the air outlet end of the fan 600. The activated carbon box 800 has an exhaust pipe 810. The collected waste gas can be purified by filtering through the activated carbon box 800 and discharged from the exhaust pipe 810, ensuring that the gas finally discharged to the outside is non-toxic and harmless.

[0025] The drug spray pipe 710 is located in the chamber 210 and is installed above the spiral blade 400. The drug spray pipe 710 extends along the length of the chamber 210 and has multiple spray ports 711 evenly distributed below. The drug spray pipe 710 is connected to a dosing pump 700 installed outside the housing 200. The dosing pump 700 is connected to the drug box 900 through a dosing pipe 720.

[0026] Here, those skilled in the art can understand that, during the process of turning the soil, spraying the agent into the soil through the agent spray pipe 710 can achieve a drug reaction on the soil, thereby releasing waste gas, and coordinating the use of the first branch pipe 620 to discharge the waste gas, effectively improving the use effect of this all-in-one machine.

[0027] Furthermore, a lining plate 240 is installed at the bottom of the chamber 210 , and a soil discharge port 230 is formed at one end of the lining plate 240 and is opened at the bottom of the shell 200 .

[0028] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
