[0055] As shown in Figure 4 and Figure 6 shown, the convenient adjusting assembly further comprises a loading driving ring 7, a matched bearing rod 76 and a loading strip plate 8, the loading driving ring 7 is movably installed on the medicine conveying pipe 2, specifically, a bearing connecting block 71 is integrally formed at one side of the loading driving ring 7, a bearing channel 72 is formed on the bearing connecting block 71, first supporting rods 25 are symmetrically welded and fixed at the upper and lower ends of the assembly connecting pipe 23, a bent plate carrier 26 is welded and fixed on the first supporting rod 25, a second supporting rod 27 is welded and fixed on the bent plate carrier 26, the second supporting rod 27 is inserted into the bearing channel 72 on the bearing connecting block 71, the second supporting rod 27 supports the loading driving ring 7 through cooperation with the bearing channel 72, so that the loading driving ring 7 can move along the second supporting rod 27.

[0056] As shown in Figure 9 the other side of the loading driving ring 7 is integrally formed with a loading connection strip 73, a connecting cavity 75 is formed on the loading connection strip 73, a matched bearing rod 76 is inserted into the connecting cavity 75, the matched bearing rod 76 is supported by the connecting cavity 75, and the matched bearing rod 76 can move along the connecting cavity 75.

[0057] As shown in Figure 4And Figure 10 As shown, the matching strip plate 8 is movably connected with the matching drive ring 7, and the matching drive ring 7 drives the matching strip plate 8 to move. The matching strip plate 8 is provided with a support matching hole 81, which is matched with the first support rod 25. The matching of the support matching hole 81 and the first support rod 25 limits the matching strip plate 8, so that the matching strip plate 8 can only move up and down along the first support rod 25. The matching strip plate 8 is integrally provided with a connecting hinge 82, and the connecting hinge 82 is hingedly connected with a connecting strip rod 79. The other end of the connecting strip rod 79 is hingedly connected with the matching drive ring 7. In addition, two matching strip plates 8 are movably connected with one matching drive ring 7, which are respectively located on the upper and lower sides of the matching drive ring 7. Specifically, the lower end of the connecting strip rod 79 hingedly connected with the matching strip plate 8 on the upper side of the matching drive ring 7 is hingedly connected with the upper end of the matching drive ring 7, and the upper end of the connecting strip rod 79 hingedly connected with the matching strip plate 8 on the lower side of the matching drive ring 7 is hingedly connected with the lower end of the matching drive ring 7. In this way, when the matching drive ring 7 moves, it can drive the two matching strip plates 8 to move.

[0058] As shown in Figure 8 And Figure 9 As shown, the matching drive ring 7 is connected with the moving adjustment pipe 4, and the matching drive ring 7 is driven by the moving adjustment pipe 4 to move. Specifically, the lower end of the moving adjustment pipe 4 is welded and fixed with a connecting strip frame 47, the connecting strip frame 47 is provided with a connecting channel 48, and the connecting strip frame 47 is integrally provided with a driving part 49. The driving part 49 is provided with a driving channel 491, and the driving channel 491 is in communication with the connecting channel 48. The width of the driving channel 491 and the connecting channel 48 is equal, and the inner wall of the driving channel 491 and the connecting channel 48 is smooth without burrs. The lower end of the matching connecting strip 73 is welded and fixed with a linkage matching rod 74, the linkage matching rod 74 is inserted into the connecting channel 48, and the linkage matching rod 74 is in contact with the inner wall of the connecting channel 48. The surface of the linkage matching rod 74 is smooth without burrs. When the moving adjustment pipe 4 moves, the linkage matching rod 74 is in the driving channel 491, and the matching of the driving channel 491 and the linkage matching rod 74 can drive the matching drive ring 7 to move.

[0059] The matching load rod 76 is welded and fixed with a load movable block 77, and the load movable block 77 is welded and fixed with a locking matching rod 78. The locking matching rod 78 is inserted into the support connecting hole 46. In this way, when the moving adjustment pipe 4 moves along the moving pipe cavity 22, the matching load rod 76 can be driven to move along the connecting cavity 75 under the matching of the locking matching rod 78 and the support connecting hole 46. When the locking matching rod 78 is inserted into the locking insertion hole 55, the second nozzle 5 can be fixed on the moving adjustment pipe 4, and the second nozzle 5 can be locked by the matching load rod 76.

[0060] As shown in Figure 5 and Figure 10 The matching strip plate 8 cooperates with the first spray head 3 to fix the first spray head 3 on the medicine delivery tube 2. Specifically, a matching lock block 83 is welded and fixed on the matching strip plate 8, a locking slot 84 is formed on the matching lock block 83, a first ring slot 85 and a second ring slot 86 are respectively formed at two ends of the locking slot 84. After the first spray pipe 31 on the first spray head 3 is inserted into the assembly connecting pipe 23, the protruding matching plate 24 is in contact with the matching ring plate 32. When the matching driving ring 7 drives the two matching strip plates 8 connected thereto to move towards each other, the protruding matching plate 24 and the matching ring plate 32 are inserted into the locking slot 84 on the matching lock block 83. Under the action of the locking slot 84, the protruding matching plate 24 and the matching ring plate 32 are locked together, thereby realizing the fixed installation of the first spray head 3 on the medicine delivery tube 2. At this time, the first ring slot 85 is in contact with the first spray pipe 31, and the second ring slot 86 is in contact with the assembly connecting pipe 23. The two matching lock blocks 83 connected by the matching driving ring 7 are closed together. Under the action of the matching lock block 83, the connection between the first spray head 3 and the assembly connecting pipe 23 can be further sealed, so that the phenomenon of liquid leakage is avoided.

[0061] When the improved agent is put, the improved agent in the medicine box 11 is pumped into the medicine delivery pipe 2 by the pump body 12, and the improved agent is sprayed and put by the first spray head 3 and the second spray head 5. In the actual use process, when the adjusting bearing plate 6 does not move downward, the distance between the first spray head 3 and the second spray head 5 is at a minimum value, the spraying range of the improved agent is the smallest at this time, and because the distance between the first spray head 3 and the second spray head 5 is the smallest, the spraying of the improved agent is the most concentrated when the improved agent is sprayed, which can adapt to the soil that needs more improved agent. When the distance between the first spray head 3 and the second spray head 5 becomes larger, the spraying range of the improved agent will become larger with the movement of the first spray head 3 at this time, and the spraying of the improved agent will become more dispersed at the same time. In this way, the amount of the improved agent put into the soil will be less for the same soil, which can adapt to the soil that needs less improved agent. With the increase of the spraying range, the spraying area of the improved agent becomes larger at the same time, which can improve the work efficiency of the improved agent put. When it is necessary to adjust the distance between the first spray head 3 and the second spray head 5 to be larger, the adjusting screw 63 is rotated to drive the adjusting bearing plate 6 to move downward under the action of the thread. With the downward movement of the adjusting bearing plate 6, the two moving adjusting pipes 4 on the medicine delivery pipe 2 will move away from each other under the action of the adjusting connecting rod 66, thereby driving the second spray heads 5 at both ends of the medicine delivery pipe 2 to move away from each other, that is, the distance between the first spray head 3 and the second spray head 5 can be adjusted, which is very convenient. When the moving adjusting pipe 4 moves, the locking matching rod 78 is inserted into the supporting connecting hole 46, so that the matching bearing rod 76 will move synchronously with the moving adjusting pipe 4, and the matching bearing rod 76 will not be separated from the connecting cavity 75. When it is necessary to disassemble the first spray head 3 and the second spray head 5, the adjusting screw 63 is rotated to drive the adjusting bearing plate 6 to move downward, thereby driving the moving adjusting pipe 4 to move, so that the linkage matching rod 74 enters the driving channel 491. In this way, with the movement of the moving adjusting pipe 4, the linkage matching rod 74 will move away from the moving adjusting pipe 4 under the action of the driving channel 491, thereby driving the matching driving ring 7 to move away from the medicine delivery pipe 2. With the movement of the matching driving ring 7, the matching bearing rod 76 will move synchronously with the matching driving ring 7. With the movement of the matching bearing rod 76, the locking matching rod 78 on the matching bearing rod 76 will exit the locking insertion hole 55 on the locking guide plate 54, but the locking matching rod 78 will not be separated from the supporting connecting hole 46. In this way, the second spray head 5 can be in an unlocked state, and the second spray head 5 can be quickly removed for necessary maintenance. With the movement of the matching driving ring 7 away from the medicine delivery pipe 2, the matching strip plate 8 connected with the matching driving ring 7 will move away from each other under the action of the connecting strip rod 79, that is, the matching strip plate 8 above the matching driving ring 7 moves upward, and the matching strip plate 8 below the matching driving ring 7 moves downward.Thus, the protruding matching plate 24 and the matching ring plate 32 are separated from the locking slot 84 on the matching lock block 83, so that the first nozzle 3 is in an unlocked state, and the first nozzle 3 can be quickly disassembled for necessary maintenance, which is very convenient, and the first nozzle 3 and the second nozzle 5 can be conveniently disassembled. Of course, when the first nozzle 3 and the second nozzle 5 are installed, it is also very convenient, that is, the first nozzle pipe 31 on the first nozzle 3 is inserted into the assembled connecting pipe 23, so that the protruding matching plate 24 is in contact with the matching ring plate 32, the positioning of the first nozzle 3 is completed, then the connecting ring cavity 53 on the second nozzle 5 is matched with the sealing connecting pipe sleeve 42 on the support disc 41, and the locking guide plate 54 is inserted into the guide channel 44 to complete the positioning of the second nozzle 5, then the adjusting screw 63 is rotated to drive the adjusting bearing plate 6 to move upwards, and with the upward movement of the adjusting bearing plate 6, the locking matching rod 78 is inserted into the locking insertion hole 55 to realize the fixation of the second nozzle 5, and under the action of the matching driving ring 7, the two matching strip plates 8 connected with the matching driving ring 7 move towards each other to close the matching lock block 83 together, and at the same time, the protruding matching plate 24 and the matching ring plate 32 are inserted into the locking slot 84 on the matching lock block 83 to realize the fixation of the first nozzle 3, which is very convenient and fast, and the operation is simple.
