Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Specific examples are given below.
[0023] See also Figure 1-4 As shown, a quantitative pesticide filling device comprises a workbench body 11; an electric push rod 12 is fixedly connected to the top of the workbench body 11; a bracket 13 is fixedly connected to the output end of the electric push rod 12; a filling tube 16 is arranged at the bottom of the bracket 13; a piston cylinder 14 is fixedly connected to the bracket 13; a piston rod 18 is slidably connected in the piston cylinder 14; a connecting hose 15 is fixedly connected between the top of the piston cylinder 14 and the filling tube 16; a suction hose 17 is fixedly connected to the top of the piston cylinder 14; and a suction hose 17 is installed on the connecting hose 15 and the suction hose 17. A one-way valve is installed; a limit assembly is provided on the side of the workbench body 11; a limit plate 19 is provided at the bottom of the limit assembly; a first screw 191 is rotatably connected to the limit plate 19; the limit assembly includes a limit seat 21; a slide rail is fixedly connected to the side wall of the workbench body 11; the limit seat 21 is slidably connected to the slide rail; a second screw 22 is rotatably connected to the side wall of the workbench body 11; the second screw 22 is threadedly connected to the limit seat 21; the first screw 191 passes through the limit seat 21 and is threadedly connected thereto;
[0024] When in use, the electric push rod 12 pushes the bracket 13 downward to drive the piston cylinder 14 and the piston rod 18 to move downward. The piston rod 18 moves downward to a certain distance, and at the same time, the filling tube 16 is inserted into the container on the workbench. As the piston rod 18 continues to move downward, it will contact the limit plate 19. The limit plate 19 is fixed differently, which will squeeze the piston rod 18. The piston rod 18 pushes the liquid squeezed from the piston cylinder 14 to be injected into the filling tube 16 through the connecting hose 15, thereby completing the liquid filling of the pesticide. The first screw 191 can be rotated to The position of the limit plate 19 can be adjusted, and then the upward movement distance of the piston rod 18 can be adjusted to control the filling amount of the pesticide liquid, so as to reduce the situation where the pesticide liquid is filled too much or too little. After the electric push rod 12 pulls the bracket 13 to move upward, the piston rod 18 is pulled downward, and the end of the suction hose 17 is inserted into the pesticide liquid container. The downward movement of the piston rod 18 is used to extract the liquid into the piston cylinder 14. The one-way valve is used to control so that the liquid in the suction hose 17 and the connecting hose 15 can only flow in one direction.
[0025] Further, such as Figure 2-3 As shown, a first spring is fixedly connected between the piston rod 18 and the piston cylinder 14; a plurality of guide rods 31 are fixedly connected to the top side of the limit plate 19; the guide rods 31 penetrate the limit seat 21 and are slidably connected thereto; when in use, the first spring is provided to pull the piston rod 18 downward, so that it is convenient for subsequent rods to extract the pesticide liquid, and the guide rods 31 can guide the up and down movement adjustment of the limit plate 19, thereby improving the stability of the limit seat 21.
[0026] Further, such as Figure 2-3 As shown, a slider 42 is fixedly connected to the filling tube 16; a limiting block 41 is slidably connected to the slider 42; a vertical rod 43 is fixedly connected to the limiting block 41; the vertical rod 43 passes through the bracket 13 and is slidably connected thereto; a second spring is fixedly connected between the limiting block 41 and the bracket 13; when in use, the staff adjusts the height of the limiting seat 21, and then the limiting block 41 moves downward, which will be blocked by the limiting seat, so as to adjust the insertion depth and height of the filling tube 16. When the limiting block 41 contacts the limiting seat 21, the limiting seat 21 will fix the filling tube 16 differently, and then the vertical rod 43 will slide upward on the bracket 13, and the second spring will be compressed. When it is pulled out, the bracket 13 will move upward first, and then the second spring will push the filling tube 16 to remain stationary, so that the mouth of the filling tube 16 can be kept in the container for a certain period of time, which is convenient for the agricultural liquid to drip into the container.
[0027] Further, such as Figure 2-3As shown, the top side of the slider 42 is fixedly connected to a first vertical plate 51; a second vertical plate 52 is fixedly connected to the bracket 13 at a position corresponding to the first vertical plate 51; the bottom of the second vertical plate 52 is in contact with the first vertical plate 51; the sides of the first vertical plate 51 and the second vertical plate 52 are both provided with semicircular protrusions; after the filling is closed, the electric push rod 12 pulls the bracket 13 to move up, and then the second spring pushes the filling tube 16 to keep different, and then the second vertical plate 52 moves up to cooperate with the side wall of the first vertical plate 51, relying on the first vertical plate 51 Cooperating with the semicircular protrusion on the second vertical plate 52, the slider 42 can be pushed to move in an staggered manner, and the filling tube 16 can be pushed to move. The filling tube 16 can be shaken to facilitate the falling of the pesticide at the bottom of the filling tube 16 and make it drip into the container, thereby reducing the dripping of the pesticide liquid onto the conveyor belt and reducing its contamination. When the container diameter is small, if the shaking of the filling tube 16 easily causes the container to shake, a fixing fixture needs to be installed on the workbench body 11 to fix the container.
[0028] Further, such as Figure 4 As shown, elastic members 6 are fixedly connected to both sides of the slider 42; the ends of the elastic members 6 are fixedly connected to the inner wall of the limit block 41; when in use, the slider 42 can drive the filling tube 16 to reset by relying on the elastic members 6, so as to facilitate use.
[0029] Further, such as Figure 2 As shown, a rubber pad 7 is fixedly connected to the top side of the limit plate 19. When in use, the rubber pad 7 is used to protect the bottom of the piston cylinder 14, thereby reducing wear.
[0030] Working principle: when in use, the electric push rod 12 pushes the bracket 13 to move downward, thereby driving the piston cylinder 14 and the piston rod 18 to move downward. The piston rod 18 moves downward to a certain distance, and at the same time, the filling tube 16 is inserted into the container on the workbench. As the piston rod 18 continues to move downward, it will contact the limit plate 19. The limit plate 19 is fixed differently, and it will squeeze the piston rod 18. The piston rod 18 pushes the liquid squeezed from the piston cylinder 14 to be injected into the filling tube 16 through the connecting hose 15, so as to complete the liquid filling of the pesticide. The position of the limit plate 19 can be adjusted by rotating the first screw 191, and then the upward movement distance of the piston rod 18 can be adjusted, so as to control the liquid filling amount of the pesticide. The control is used to reduce the situation where too much or too little pesticide liquid is poured in. After the electric push rod 12 pulls the bracket 13 to move up, the piston rod 18 is pulled down, and the end of the suction hose 17 is inserted into the pesticide liquid container. The downward movement of the piston rod 18 is used to extract the liquid into the piston cylinder 14. The one-way valve is used to control so that the liquid in the suction hose 17 and the connecting hose 15 can only flow in one direction. By setting a first spring, the piston rod 18 can be pulled down to facilitate the subsequent rod to extract the pesticide liquid. The guide rod 31 can guide the up and down movement adjustment of the limit plate 19 to improve the stability of the limit seat 21. The staff adjusts the height of the limit seat 21 and then limits the limit. When the stop block 41 moves downward, it will be blocked by the limiting seat, so as to adjust the insertion depth and height of the filling tube 16. When the stop block 41 contacts the limiting seat 21, the limiting seat 21 will fix the filling tube 16. Then the vertical rod 43 will slide upward on the bracket 13, and the second spring will be compressed. When it is pulled out, the bracket 13 will move upward first, and then the second spring will push the filling tube 16 to remain stationary, so that the mouth of the filling tube 16 can be kept in the container for a certain period of time, which is convenient for the agricultural liquid to drip into the container. After the filling is closed, the electric push rod 12 pulls the bracket 13 to move upward, and then the second spring pushes the filling tube 16 to remain unchanged, and then the second vertical plate 52 moves upward to align with the side of the first vertical plate 51. The wall cooperates with the semicircular protrusions on the first vertical plate 51 and the second vertical plate 52, so that the slider 42 can be pushed to move alternately, and the filling tube 16 can be pushed to move. The filling tube 16 is shaken to facilitate the falling of the pesticide at the bottom of the filling tube 16 and drip it into the container, thereby reducing the dripping of the pesticide liquid onto the conveyor belt and reducing its contamination. When the container diameter is small, if the shaking of the filling tube 16 easily causes the container to shake, a fixing fixture needs to be installed on the workbench body 11 to fix the container, and the elastic member 6 is set to facilitate the slider 42 to drive the filling tube 16 to reset, so as to facilitate use.
