[0106] Before the device runs, first, the user digs a soil pit on the farmland 11 to be repaired, the length and width of the soil pit are equal to the outer contour size of the device, and the depth is less than the height of the device, and places the device at the bottom of the inner cavity of the soil pit, so that the tail end bottom of the feeding chute 96 abuts against the inner cavity bottom surface of the soil pit, then the user throws the biomass fuel on the top of the bearing plate 701 in the heating cavity 622 through the filling port 703, and ignites it; when the device runs, the electric hydraulic push rod 4 pushes the bulldozing plate 5 at the rear side of the device to the rear side vertical wall of the soil pit to apply a pushing force, and drives the device to displace forward by the reaction force of the rear side vertical wall of the soil pit, and then applies pressure to the plurality of roller shafts 81 through the bearing support 3; at the same time, the third motor 84 drives the driving sprocket 83 to rotate, the driving sprocket 83 drives a group of driven sprockets 82 to rotate synchronously through the power transmission of one of the first transmission chains 85, and then drives the plurality of roller shafts 81 to rotate, in the process of rotating, the roller shaft 81 scrapes the soil on the front side vertical wall of the soil pit through the first digging tooth 811, and piles it on the bottom of the inner cavity of the soil pit, the roller shaft 81 drives another group of driven sprockets 82 to rotate synchronously while rolling, and then drives another first transmission chain 85 to transmit power, the second digging tooth 812 arranged on the outer ring surface of the two transmission chains scrapes the soil protruding on the side walls of the soil pit, and piles it on the bottom of the inner cavity of the soil pit, so as to ensure that the width of the soil pit is always not less than the outer contour width of the device during the forward movement of the device, when the soil on the front side vertical wall of the soil pit is excavated to a certain depth, the actuator end of the electric hydraulic push rod 4 is also elongated, which pushes the device to displace forward, so that the plurality of roller shafts 81 can always abut against the front side vertical wall of the soil pit, after the device displaces a certain distance in the soil pit, the electric hydraulic push rod 4 drives the bulldozing plate 5 to reset, so that the cavity is formed between the bulldozing plate 5 and the rear side vertical wall of the soil pit.

[0107] During the forward displacement of the device, the roller 2 reduces the friction between the device and the inner cavity bottom wall of the pit by rolling, and the feeding chute 96 collects the soil accumulated at the bottom of the inner cavity of the pit and conveys it to the first feeding port 92 of the feeding shell 91, while the fourth motor 974 drives one of the feeding sprockets 972 to rotate, which drives the remaining feeding sprockets 972 to rotate synchronously through the power transmission of the feeding transmission chain 973, thereby driving a plurality of feeding auger shafts 95 to rotate. The feeding auger shafts 95 convey the soil at the first feeding port 92 to the first discharge port 93 during rotation, so that it falls through the feeding hopper 67 to the inner cavity bottom of the feeding shell 692; at the same time, the first motor 697 drives the first auger shaft 696 to rotate, which conveys the soil accumulated at the bottom of the inner cavity of the feeding shell 692 to the deep inner cavity of the roller 693. During the conveying of the soil by the first auger shaft 696 to the deep inner cavity of the roller 693, the second motor 698 drives the roller 693 to rotate, and the soil lumps in the soil are ground into soil particles with an outer diameter smaller than the size of the screen hole 694 by the protrusions 695 arranged on the inner surface of the roller 693. Hard protrusions will be continuously conveyed to the tail end of the inner cavity of the roller 693, and the soil subsequently poured into the tail end of the inner cavity of the roller 693 will apply pressure to the protrusions located at the tail end of the inner cavity of the roller 693 until the protrusions are ground by the protrusions 695 on the inner surface of the tail end of the inner cavity of the roller 693. The ground soil falls through the screen hole 694 opened on the outer wall of the roller 693, and finally falls through the discharge port 63 into the discharge chamber 631. The soil falling into the discharge chamber 631 slides towards the discharge port 64 through the guide plate 65 and finally discharges through the discharge port 64 to the feeding passage 102; while the first motor 697 drives the first auger shaft 696 to rotate, the air pump 711 is started to exhaust the air in the discharge chamber 631, so that external air enters the inner cavity of the feeding shell 692 through the feeding hopper 67, and then enters the discharge chamber 631 through the roller 693, the screen hole 694 and the discharge port 63, and is finally exhausted by the air pump 711. In addition, the user can also adjust the combustion efficiency of the fuel by adjusting the working efficiency of the air pump 711, thereby controlling the temperature of the soil heated by the device.The outside air also enters the heating cavity 622 through the ventilation hole 702 and the second through hole 7011 opened on the bearing plate 701, and then enters the inner cavity of the roller 693 through the first through hole 661 opened at the head end of the vertical partition plate 66 and the inner cavity of the feeding shell 692 in sequence, so as to bring the heat generated in the fuel combustion process into the roller 693, heat the soil in the inner cavity of the roller 693, accelerate the volatilization of the accumulated harmful substances in the soil into the air, and dry the soil at the same time, so that the soil is more easily ground. The air in the inner cavity of the roller 693 enters the discharge cavity 631 through the sieve hole 694 and the discharge port 63 in sequence, and is finally extracted by the air pump 711, so that the discharge cavity 631 always maintains a negative pressure state. The filter 712 filters the gas discharged by the air pump 711 to avoid the harmful gas emitted by the soil and the harmful gas generated in the fuel combustion process from being discharged into the air to pollute the air.

[0108] At the same time when the soil is discharged from the discharge port 64 to the feeding channel 102, the water pump 68 outputs the improvement agent pre-stored in the liquid storage cavity 632 into the feeding channel 102, so that the soil in the feeding channel 102 is absorbed. The soil in the feeding channel 102 is conveyed to the second discharge port 103 by the discharging spiral conveying shaft 105, and finally discharged by the discharging chute 106. The soil discharged by the discharging chute 106 slides along the slope of the bulldozing plate 5 to the bottom of the cavity between the bulldozing plate 5 and the soil pit, and is compacted with the next pushing of the bulldozing plate 5.

[0109] The above, with reference to Figures 1 to 15 The repair equipment for farmland soil pollution treatment according to the embodiment of the application is described, and has the following beneficial effects: the automatic feeding of soil during the repair treatment of the soil by the device is realized through the cooperative operation among the digging module, the electric hydraulic push rod and the bulldozing plate, the user does not need to actively dig the soil, the defect of poor convenience in the prior art is solved, and the labor cost of soil repair operation is saved.
