A plurality of air bags 304 are fixedly connected to the outer surface of the connecting frame 316. When the liquid height in the material limiting barrel 301 exceeds the height of the air bags 304, the air bags 304 move upward under the action of buoyancy, and then the screw rod 303 can be driven to move through the connecting frame 316.

[0044] like Figure 8 , 9 A floating block 311 is slidably mounted on the inner end of the isometric cylinder 302, a magnet is fixedly mounted on the inner end of the floating block 311, and the connecting frame 316 is made of metal, so that when the connecting frame 316 moves, the floating block 311 can be driven to move under the traction of the magnetic force, and the upper end of the floating block 311 is penetrated in the air pipe 11, and an extension tube is fixedly mounted on the inner end of the air pipe 11, and an air outlet is provided at one end of the extension tube close to the floating block 311, and an air inlet 312 is provided at the upper end of the floating block 311, and when the floating block 311 continues to move upward, the air inlet 312 corresponds to the air outlet;

[0045] like Figure 8 , 10The upper end of the floating plate 306 is rotatably installed with a wire wheel 305, and a traction line 310 is wound on the outer surface of the wire wheel 305. A through hole is opened on the outer surface of the iso-height cylinder 302, and the free end of the traction line 310 passes through the through hole and is fixedly connected to the bottom end of the floating block 311.

[0046] Example 3: Please refer to Figure 3 , 8 , a land ecological environment restoration device, based on the embodiment 1, a plug 309 is fixedly installed at the bottom end of the screw 303, and a triangular block 308 is slidably installed at the inner end of the plug 309, and the triangular block 308 is connected to the plug 309 by a spring sheet, and a communicating vessel 13 is fixedly installed at the bottom end of the limiting barrel 301, and the plug 309 is slidably connected to the communicating vessel 13. A limiting groove is provided on the inner wall of the communicating vessel 13. After the plug 309 moves upward for a certain distance, the triangular block 308 is ejected under the elastic force of the spring sheet when it reaches the limiting groove. Specifically, the output end of the equal height barrel 302 is fixedly connected to the communicating vessel 13, and its output port corresponds to the plug 309. The output end of the communicating vessel 13 is fixedly connected with an output pipe 12, and the output pipe 12 is fixedly connected to the spraying pipe 101. More specifically, the output port of the communicating vessel 13 is parallel to the plug 309. Whenever the plug 309 moves upward, the output port is exposed in the communicating vessel 13;

[0047] More specifically, a conduction valve (not shown) is fixedly installed at the inner end of the feed pipe 102, and the switch of the conduction valve is fixedly connected to the plug 309. When the liquid height in the limiting barrel 301 lifts the airbag 304, the plug 309 also moves upward, and the conduction valve is closed at this time, and the injection of the bacteria source into the limiting barrel 301 is stopped;

[0048] See also Figure 3 , 11An extension rod is fixedly installed on the upper end of the screw 303, and the extension rod is connected to the limiting barrel 301 through a sealing rubber ring. A passive gear 106 is fixedly installed on the upper end of the extension rod. An adjusting rod 105 is passed through the right end of the device box 8. A crown gear 107 is fixedly installed on the end of the adjusting rod 105 close to the screw 303. The crown gear 107 is meshed with the passive gear 106, and a knob is fixedly installed on the end of the adjusting rod 105 away from the screw 303.

[0049] The working principle of the present invention is:

[0050] When in use, add a proper amount of bacteria source into the water tank 3, rotate the swirl to adjust the appropriate area spraying dosage, rotate the knob to drive the adjusting rod 105 to rotate, and the adjusting rod 105 drives the screw 303 to rotate through the meshing action of the crown gear 107 and the passive gear 106. At this time, the screw 303 rotates and drives the connecting frame 316 to move and stay at a specified height. At this time, the floating block 311 moves upward under the traction of the magnetic force. Under the action of the height difference, the bacteria source flows from the feeding pipe 102 to the limiting barrel 301. When the liquid level of the bacteria source is waiting to lift the airbag 304, the conduction valve is closed at this time, and the bacteria source is stopped from being added to the limiting barrel 301. At this time, the screw 303 drives the plug 309 to move upward during the upward movement, and the communicating vessel 13 is in an open state;

[0051] Then the engine 4 is started, and the output end of the engine 4 drives the rotary cutter 6 to rotate through the belt 5. With the rotation of the rotary cutter 6, the soil surface is crushed, and then the device is pushed to move through the support rod 2. The roller 7 rotates under the action of friction and drives the passive wheel 201 to rotate through the toothed belt 202. At this time, the propulsion tube 204 starts to rotate under the action of the rotational force of the conical block 208. The propulsion tube 204 drives the stabilizing tube 207 to rotate. At this time, the inclined plate 215 inside the stabilizing tube 207 drives the piston 214 to reciprocate under the action of the rotational force through the movable rod 212 and the push rod 213. Then, the reciprocating motion of the piston 214 and the disconnection of the sealing plate and the piston 214 will fill the right chamber of the piston 214 with air. At this time, the diameter of the ring formed by the multiple expansion plates 203 becomes larger, and its rotation speed is equivalent to the rotation speed of the shaft 104.

[0052] At the same time, when the stabilizing tube 207 rotates, the blower 205 starts to work under the meshing action of the driving gear 211 and the driven gear 206, and the blown gas comes into the contour cylinder 302 through the air pipe 11. The floating block 311 connects the air inlet 312 with the air outlet under the traction of buoyancy and magnetic force. At this time, the gas is ejected from the output end of the floating block 311. Under the action of air pressure, the bacteria source is ejected from the output port of the contour cylinder 302. Due to the reduction of liquid inside the limiting barrel 301, the air bag 304 is no longer affected by buoyancy. However, since the output port of the contour cylinder 302 is directly opposite to the bottom end of the plug 309, and the floating plate 306 is still soaked in the liquid at this time, the plug 309 can continue to maintain its current position under the impact force of the ejection and the buoyancy of the floating plate 306.

[0053] Subsequently, the bacterial liquid flows from the output pipe 12 to the spraying pipe 101, and is finally sprayed out and combined with the crushed soil, waiting for the liquid in the limiting barrel 301 to decrease until the floating plate 306 is no longer affected by the buoyancy and begins to descend. At this time, the plug 309 also begins to descend, and the conduction valve is reopened. The water tank 3 refills the liquid into the limiting barrel 301, and a new round of bacterial source spraying is started, thereby reducing the amount of sprayed bacterial liquid and effectively saving bacterial liquid.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
