[0048] With reference to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the lifting piece 6 matched with the driving piece 5 is arranged in the moving frame 1, the lifting piece 6 comprises a second bearing 61 installed on the moving frame 1, a threaded cylinder 62 installed on the second bearing 61, a plurality of first fixed blocks 63 fixedly connected with the inner side wall of the threaded cylinder 62 and matched with the first telescopic rotating blocks 53, a lifting plate 64 threadedly installed on the threaded cylinder 62, and a plurality of limiting blocks 65 fixedly connected with the side wall of the lifting plate 64 and slidably connected with the moving frame 1, and more specifically, a plurality of sliding grooves matched with the limiting blocks 65 are arranged on the side wall of the moving frame 1, and the limiting blocks 65 are slidably connected with the sliding grooves.

[0049] With reference to Figure 6 , Figure 7 and Figure 8 , the pushing piece 7 is installed on the lifting piece 6, the pushing piece 7 comprises a third bearing 71 installed on the lower end face of the lifting plate 64, a pushing cylinder 72 connected with the third bearing 71, a plurality of second fixed blocks 73 fixedly connected with the inner side wall of the pushing cylinder 72 and matched with the second telescopic rotating blocks 56, a fourth bearing 74 installed on the lower end of the pushing cylinder 72, a conical block 75 installed on the lower end of the fourth bearing 74, and a plurality of soil breaking pieces 76 installed on the side wall of the fourth bearing 74.

[0050] With reference to Figure 8 and Figure 9 , the soil breaking piece 76 comprises a soil breaking plate 761 fixedly installed on the side wall of the fourth bearing 74, and more specifically, the lower end of the soil breaking plate 761 is sharp, the upper end of the soil breaking plate 761 is fixedly connected with a leveling frame 762, the side wall of the leveling frame 762 is provided with a sawtooth strip 763, a plurality of soil penetrating spikes 764 are fixedly connected with the side wall of the sharp end of the soil breaking plate 761, and a strong rib 765 is installed on each of the soil penetrating spikes 764.

[0051] In actual operation, when the staff needs to use the device, first the staff pushes the device to the appropriate position, and then the staff can start the motor 51. When the motor 51 is working, the rotating rod 52 can be rotated. It is particularly noted that at this time, the first telescopic rotating block 53 can move out of the rotating rod 52 with the assistance of the electromagnet, so that the first telescopic rotating block 53 is located on one side of the first fixed block 63. At this time, when the rotating rod 52 rotates, the threaded cylinder 62 can be rotated. When the threaded cylinder 62 rotates, the lifting plate 64 is screwed with the threaded cylinder 62, and the limiting block 65 can limit the lifting plate 64. Therefore, the lifting plate 64 can move downward, so that the tapered block 75 and the soil breaking piece 76 on the pushing cylinder 72 can gradually insert into the soil. More specifically, the pushing cylinder 72 can normally move downward with the assistance of the lifting plate 64. At this time, the tapered block 75 can make the pushing cylinder 72 enter the soil better, reduce the insertion force of the pushing cylinder 72, and the soil-piercing spike 764 on the soil breaking piece 76 can effectively break the soil. At this time, the sharp shape at the lower end of the soil breaking plate 761 can effectively make the soil breaking plate enter the soil. It is particularly noted that the strong rib 765 can increase the stability of the soil-piercing spike 764. It is particularly noted that the leveling frame 762 can effectively form a cavity above the soil breaking plate 761, which further facilitates the entry of the soil breaking piece 9. It is particularly noted that the sawtooth strip 763 can make the cavity formed by the movement of the leveling frame 762 more stable and shaped, so as to ensure that the soil breaking piece 9 enters without problems.

[0052] With reference to Figure 6 , Figure 7 and Figure 8 , the input member 8 is installed on the pushing member 7, and the input member 8 is connected with the output end of the liquid medicine tank 4. The input member 8 includes a sleeve ring 83 sleeved on the pushing cylinder 72. It is particularly noted that the sleeve ring 83 and the pushing cylinder 72 are connected and communicated. More specifically, the side wall of the pushing cylinder 72 is provided with a conveying cavity, and the sleeve ring 83 and the conveying cavity are connected and communicated. The connection between the sleeve ring 83 and the pushing cylinder 72 is provided with two sealing bearings 84. The lower end surface of the lifting plate 64 is fixedly installed with a mounting seat 81. The mounting seat 81 is provided with a liquid inlet pipe 82 connected with the sleeve ring 83. The input end of the liquid inlet pipe 82 is connected with the output end of the pump body in the liquid medicine tank 4.

[0053] With reference to Figure 7 and Figure 10The pusher 7 is equipped with multiple soil-breaking components 9, including soil-breaking blades 91 mounted on the side wall of the pusher cylinder 72. Notably, the soil-breaking blades 91 are made of tungsten steel or high-strength steel to ensure the normal operation of the device. One end of the soil-breaking blade 91 in the direction of movement is sharp, allowing it to penetrate the soil more effectively. A partition plate 92 is fixedly connected to the inner side wall of the soil-breaking blade 91. Multiple diversion cylinders 93 are mounted on the side wall of the partition plate 92. Each of the multiple diversion cylinders 93 has a diversion cavity 94. Notably, the diversion cavity 94 is Y-shaped, allowing the liquid to flow out normally. The output end of the diversion cavity 94 has an output port 95. Notably, the output port 95 is located on the end face of the soil-breaking blade 91 in the direction of movement, which effectively increases the soil-breaking efficiency of the soil-breaking blade 91.

[0054] Reference Figure 10 and Figure 11 The flow divider 93 is equipped with an inlet 931, and an output plate 932 is fixedly connected to the inner wall of the flow divider 93. Notably, the output plate 932 is located in the middle region of the flow divider cavity 94. A rotating rod 933 extends through the flow divider 93, and multiple turbine blades 934 are fixedly connected to the side wall of the rotating rod 933. More specifically, the inlet 931 is located on one side of the turbine blades 934; more precisely, the direction in which the inlet 931 is aligned is towards the direction of rotation of the turbine blades 934, thus ensuring that the turbine blades 934 are aligned correctly. The turbine blade 932 is constantly rotating, and an outlet is also provided on the output plate 932. It is particularly noteworthy that the outlet is located on the other side of the turbine blade 934, which ensures the normal discharge of the liquid medicine. Two symmetrical striking rods 935 are fixedly connected to the side wall of the rotating rod 933. Two springs 936 are fixedly connected to the inner side wall of the soil breaking blade 91. One end of each spring 936 is fixedly connected to a striking ball 937. Multiple vibrating balls 938 are provided inside the striking ball 937. A vibrating plate 939 located on one side of the striking ball 937 is fixedly connected to the side wall of the soil breaking blade 91.

[0055] Reference Figure 10 A heat exchange block 941 is fixedly connected to the inner wall of the flow divider 93. A heat exchange rod 942 passing through the side wall of the flow divider 93 is fixedly connected to the side wall of the heat exchange block 941. A reinforcing rib 943 connected to the soil breaking blade 91 is fixedly connected to one end of the heat exchange rod 942.

[0056] In actual operation, after the soil-breaking blade 93 enters the soil, the operator can activate the electromagnet, which extends the second retractable rotating block 56. Simultaneously, the electromagnet near the first retractable rotating block 53 stops working, allowing the first retractable rotating block 53 to retract into the rotating rod 52. Then, the motor 51 continues to operate, causing the rotating rod 52 to rotate. It is particularly noteworthy that the second retractable rotating block 56 is located to one side of the second fixed block 73. Therefore, when the rotating rod 52 rotates, with the assistance of the third bearing 71, the push cylinder 72 rotates. When the push cylinder 72 rotates, the soil-breaking blade 91 rotates. It is also noteworthy that at this time, the pump in the chemical tank 4 is activated. The system begins operation, allowing the liquid medicine in the liquid medicine tank 4 to enter the inlet pipe 82. With the assistance of the collar 83 and the sealing bearing 84, the liquid medicine enters the push cylinder 72. It is important to note that the push cylinder 72 and the soil-breaking blade 91 are connected, and a sealing gasket is provided at the connection between the two. The sealing gasket contains a reinforcing rod, thereby increasing the sealing and stability of the two. The soil-breaking blade 91 is fixed in the push cylinder 72 by a plastic rod, further ensuring the stability and a certain degree of toughness of the soil-breaking blade 91. When the liquid medicine enters the soil-breaking blade 91, and the soil-breaking blade 91 rotates continuously, the soil is broken up, and the liquid medicine can also enter the soil, thereby effectively treating the soil.

[0057] During the aforementioned operation, after the liquid enters the distributor cylinder 93 through the inlet 931, it impacts the turbine blades 934, causing the rotating rod 933 to rotate. When the rotating rod 933 rotates, the striking rod 935 strikes the striking ball 937. One end of the striking ball 937 is connected to a spring 936. With the assistance of the vibrating ball 938 and the vibrating plate 939, the soil-breaking blade 91 can have a certain vibration force, thereby improving the soil-breaking effect of the soil-breaking blade 91. It is particularly noteworthy that after the liquid enters the distributor cylinder 93, it can be sprayed out from the outlet 95, which can carry away the heat from the heat exchange block 941. It is also noteworthy that the reinforcing block 943 not only increases the robustness of the soil-breaking blade 91, but also works in conjunction with the heat exchange rod 942 to transfer heat to the heat exchange block 941, further ensuring the normal operation of the soil-breaking blade 91.

[0058] Finally should be explained a few points are: first, in the description of the present application, it should be pointed out that, unless otherwise specified and limited, the term "installation", "connected", "connection" should be broad, can be mechanical or electrical connection, but also can be two elements inside the communication, can be directly connected, "up", "down", "left", "right" and so on, only for indicating the relative position relationship, when the absolute position of the described object changes, the relative position relationship may change;

[0059] Second: the present application discloses the embodiment in the drawing, only relates to the structure involved in the present application, other structures can refer to the usual design, in the case of no conflict, the same embodiment and different embodiments of the present application can be combined with each other;
