[0009] As a further description of the above technical solution:
[0010] A medicine box is fixedly connected to the bottom front side of the support plate. Two fixing blocks are fixedly connected to the inner rear side of the medicine box. A motor b is fixedly connected to the inner rear side of the medicine box. A cylinder is fixedly connected to the drive end of the motor b.

A medicine injection port is fixedly connected to the interior of the top plate. A top cover is fixedly connected to the top of the medicine injection port.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, the sliding column is pushed down into the slide plate. The slide plate has two notches inside, the diameter of which is larger than the diameter of the locking ball, so that the locking ball can slide freely inside. When the sliding column reaches the notch during its descent, it pushes the two locking balls to slide towards the side of the two notches. The two locking balls simultaneously push the ball inside the sliding column closer to each other. The spring has its own elasticity and bounces upward. When the two notches of the sliding column slide down to the position of the two notches, the spring has its own elasticity and rebounds, which drives the baffle to push the two balls towards the lower left and lower right corners and closer to the two locking balls. It pushes the two locking balls to slide towards the side of the two notches and locks them into the two grooves of the slide plate, fixing the slide plate in place. The blade can be disassembled and replaced with different weeding tools to remove different types of weeds, which is highly flexible.
[0015] 2. In this utility model, the herbicide is poured into the inlet and flows into the inside of the medicine box. The bottom plate has a mesh screen to facilitate the gradual delivery of the herbicide to the top of the horizontal plate. The right side of the horizontal plate is a certain distance from the edge of the medicine box to facilitate secondary control of the herbicide flow. When it flows to the grid plate, it passes through a finer mesh screen, and the herbicide is controlled a third time before flowing into the furrows from the inlet, inhibiting the growth of weeds for a certain period of time and preventing the waste of herbicide. The motor b drives the balance block on the cylinder to rotate. The balance block is an irregular block that reciprocates against the right side wall of the medicine box, pushing the herbicide in the medicine box to fall, which facilitates secondary elimination of weeds.

The inside of the slide plate 5 is slidably connected to the two retaining balls 11 on the opposite side.
[0025] A rectangular support plate 14 is fixedly connected to the rear side of the outer shell 1, which has good load-bearing capacity. A top plate 15 is fixedly connected to the top of the support plate 14, which serves to protect and connect other components. A push handle 16 is fixedly connected to the rear top of the support plate 14. The surface is covered with a non-slip rubber sleeve for easy gripping by operators. A rotating shaft 17 is fixedly connected inside the push handle 16. It has high strength and good toughness. Two wheels 18 are rotatably connected to the outside of the rotating shaft 17, which has good shock absorption performance and grip, and can travel smoothly between wheat ridges.
[0026] Reference Figure 2 , Figure 3 and Figure 5A medicine box 19 is fixedly connected to the bottom front side of the support plate 14, which has good chemical corrosion resistance. Two fixing blocks 20 are fixedly connected to the rear side of the inside of the medicine box 19. A motor b21 is fixedly connected to the rear side of the inside of the medicine box 19. A cylinder 22 is fixedly connected to the drive end of the motor b21. Two balance blocks 23 are rotatably connected to the outside of the cylinder 22. A bottom plate 24 is fixedly connected to the front side of the inside of the medicine box 19 to hold the herbicide inside and perform initial control of the herbicide. A horizontal plate 25 is fixedly connected to the front side of the inside of the medicine box 19. The right side of the horizontal plate 25 is a certain distance from the edge of the medicine box 19 to facilitate secondary control of the herbicide flow. A grid plate 26 with multiple through holes is fixedly connected to the herbicide tank 19 for three-stage filtration. A dispensing port 12 is provided at the bottom of the tank to deliver the herbicide to the weeding area, inhibiting weed growth for a certain period of time and preventing herbicide waste. The bottom of the base plate 24 is located at the top of the horizontal plate 25, the bottom of the horizontal plate 25 is located at the top of the grid plate 26, and the bottom of the grid plate 26 is located at the top of the dispensing port 12.

A top cover 28 with a sealing rubber ring is fixedly connected to the top of the injection port 27 to prevent herbicide leakage.
[0027] Compared with some existing devices, the above-mentioned device makes the weeding blades of the weeding machine detachable, which facilitates the replacement of different blades, adapts to the diversity of weed types, and improves the ability to remove different types of weeds.
[0028] Working principle: By pushing the slide column 6 down into the slide plate 5, the slide plate 5 has two notches inside. The diameter of the round opening 10 is larger than the diameter of the locking ball 11, which allows the locking ball 11 to slide freely inside. When the slide column 6 reaches the round opening 10 during its descent, it pushes the two locking balls 11 to slide towards the side of the two round openings 10. At the same time, the two locking balls 11 push the round ball 9 inside the slide column 6 closer to each other. The spring 7 has its own elasticity and bounces upward. When the two notches of the slide column 6 slide down to the position of the two round openings 10, the spring 7 has its own elasticity and bounces back, which drives the baffle 8 to push the two round balls 9 towards the lower left and lower right corners to approach the two locking balls 11. It pushes the two locking balls 11 to slide towards the side of the round opening 10 and get stuck in the two grooves of the slide plate 5, fixing the slide plate 5. The blade 13 can be disassembled and replaced with different weeding tools to remove different types of weeds, which is highly flexible.
[0029] By pouring the herbicide into the inlet 27, it flows into the interior of the medicine tank 19. The bottom plate 24 has a mesh screen, which facilitates the gradual delivery of the herbicide to the top of the horizontal plate 25. The right side of the horizontal plate 25 is a certain distance from the edge of the medicine tank 19, which facilitates secondary control of the herbicide flow. When it flows to the grid plate 26, it passes through a finer mesh screen, and the herbicide is controlled a third time. Then it flows into the field ridges from the inlet 12, inhibiting the growth of weeds for a certain period of time and preventing the waste of herbicide. The motor b21 is started to drive the balance block 23 on the cylinder 22 to rotate. The balance block 23 is an irregular block that reciprocates against the right wall of the medicine tank 19, pushing the herbicide in the medicine tank 19 to fall, which facilitates secondary elimination of weeds.
