Description

Technical Field

[0001] This utility model relates to the field of pesticide filling technology, and in particular to an insertable pesticide safety filling mechanism. Background Technology

[0002] As an indispensable production material in modern agriculture, the safety of pesticides during production, packaging, transportation, and use is of paramount importance. To increase the safety of pesticide filling and prevent pesticide spillage from harming workers, the filling head is often inserted directly into the bottle. However, due to work errors or equipment problems, sometimes filling begins before the filling head is inserted into the bottle, leading to pesticide spillage and posing a significant safety hazard to workers.

[0003] Therefore, an insertable pesticide safety filling mechanism is needed. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing an extended-type pesticide safety filling mechanism. This mechanism uses an electric push rod to drive the filling tube and clamping block to move vertically. After the clamping block contacts the medicine bottle, it moves relative to the filling tube. The relative movement of the clamping block on the filling tube controls the piston valve to open and close the filling tube, thereby preventing filling from taking place before the filling tube enters the medicine bottle and increasing the safety of filling.

[0005] This utility model is achieved through the following technical solution: It provides an insertable pesticide safety filling mechanism, including a support frame, a filling tube extending vertically on the support frame, and an electric push rod that drives the filling tube to move vertically. The filling tube is connected to an infusion tube. A clamping block is slidably fitted onto the filling tube, and the movement trajectory of the clamping block intersects with the mouth of the pesticide bottle. A piston valve is provided inside the filling tube, and the piston valve is connected to the clamping block. The electric push rod drives the filling tube and the clamping block to move vertically. After the clamping block contacts the pesticide bottle, it moves relative to the filling tube. The relative movement of the clamping block on the filling tube controls the piston valve to open and close the filling tube, thereby preventing filling before the filling tube enters the pesticide bottle and increasing filling safety.

[0006] As an optimization, the clamping block is connected to the filling tube via a return spring, with the axis of the return spring extending vertically. The return spring increases the pressure between the clamping block and the medicine bottle, preventing the medicine bottle from shaking during filling and thus preventing it from tipping over, thereby increasing the safety of pesticide filling.

[0007] As an optimization, the bottom of the filling tube is connected to a frustum-shaped filling head extending vertically. The piston valve is adapted to the filling head, and the piston valve has a liquid delivery channel connecting the upper and lower sides of the piston valve. Pesticide delivery stops when the piston valve is in contact with the filling head, and starts when the piston valve is away from the filling head.

[0008] As an optimization, the bottom of the piston valve is equipped with a cone that matches the filling head, and the height of the cone is greater than the height of the filling head. By passing the cone through the filling head, the area at the bottom of the filling head is reduced, allowing the pesticide at the bottom of the filling head to converge along the cone, accelerating the dripping of the pesticide, preventing the pesticide from dripping outside the bottle, and increasing the safety of pesticide filling.

[0009] As an optimization, the bottom of the clamping block is equipped with an anti-slip pad; the anti-slip pad prevents the medicine bottle from sliding, thereby preventing the medicine bottle from tipping over and increasing the safety of pesticide filling.

[0010] As an optimization, the anti-slip pad is provided with ventilation holes, which connect the inside and outside of the medicine bottle. The ventilation holes connect the inside and outside of the medicine bottle, preventing the internal air pressure of the medicine bottle from rising during the filling process, which would affect the filling efficiency and prevent the medicine bottle from separating from the clamping block.

[0011] The beneficial effects of this utility model are as follows: The electric push rod drives the filling tube and clamping block to move vertically. After the clamping block contacts the medicine bottle, it moves relative to the filling tube. The relative movement of the clamping block on the filling tube controls the piston valve to open and close the filling tube, thus preventing filling before the filling tube enters the medicine bottle and increasing filling safety. The return spring increases the pressure between the clamping block and the medicine bottle, preventing the medicine bottle from shaking during filling and thus preventing it from tipping over, increasing pesticide filling safety. The cone-shaped tip passes through the filling head, reducing the area at the bottom of the filling head, causing the pesticide at the bottom of the filling head to converge along the cone, accelerating pesticide dripping and preventing pesticide from dripping outside the medicine bottle, further increasing pesticide filling safety.

[0017] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0018] like Figures 1-3 The extended pesticide safety filling mechanism of this utility model includes a support 1, a filling tube 2 extending vertically on the support 1, and an electric push rod 3 for driving the filling tube 2 to move vertically. The filling tube 2 is connected to an infusion tube 4. A clamping block 5 is slidably sleeved on the filling tube 2, and the movement trajectory of the clamping block 5 intersects with the mouth of the medicine bottle 12. A piston valve 6 is provided inside the filling tube 2, and the piston valve 6 is connected to the clamping block 5. A placement platform 11 for placing the medicine bottle 12 is fixed on the support 1, and the placement platform 11 is placed horizontally. The electric push rod 3 is existing technology.

[0019] Place the medicine bottle 12 directly below the filling tube 2, and start the electric push rod 3. The electric push rod 3 drives the filling tube 2 and the clamping block 5 to move vertically downwards until the bottom of the filling tube 2 passes through and enters the medicine bottle 12. The electric push rod 3 drives the filling tube 2 and the clamping block 5 to continue moving vertically downwards. The clamping block 5 contacts the mouth of the medicine bottle 12. The electric push rod 3 drives the filling tube 2 to continue moving vertically downwards. The clamping block 5 slides relative to the filling tube 2 and drives the piston valve 6 to move. The piston valve 6 opens and the electric push rod 3 closes. The infusion tube 4 infuses pesticide into the medicine bottle 12 through the filling tube 2.

[0020] After the pesticide filling is about to be completed, the electric push rod 3 is activated. The electric push rod 3 drives the filling tube 2 to move vertically upward. Under the action of gravity, the clamping block 5 slides relative to the filling tube 2 and drives the piston valve 6 to move. The piston valve 6 closes, and the filling tube 2 stops filling the pesticide into the bottle 12. The electric push rod 3 drives the filling tube 2 to move vertically upward. The clamping block 5 disengages from the bottle mouth of the pesticide bottle 12 and moves vertically upward with the filling tube 2 until the bottom of the filling tube 2 disengages from the pesticide bottle 12. The electric push rod 3 is then turned off, and the filling tube 2 and the clamping block 5 stop moving.

[0021] like Figures 1-3 The clamping block 5 shown is connected to the filling tube 2 via a reset spring 7, the axis of which extends vertically. The reset spring 7 can be connected to the filling tube 2 via a pressure sensor, and the pressure sensor is connected to the electric push rod 3, so that the electric push rod 3 automatically closes after the pesticide filling begins.

[0022] Start the electric push rod 3. The electric push rod 3 drives the filling tube 2, clamping block 5 and return spring 7 to move vertically downward until the bottom of the filling tube 2 passes through and enters the medicine bottle 12. The electric push rod 3 drives the filling tube 2, clamping block 5 and return spring 7 to continue moving vertically downward. The clamping block 5 contacts the mouth of the medicine bottle 12. The electric push rod 3 drives the filling tube 2 to continue moving vertically downward. The clamping block 5 slides relative to the filling tube 2. The return spring 7 retracts. The clamping block 5 drives the piston valve 6 to move. The piston valve 6 opens and closes the electric push rod 3.

[0023] After the pesticide filling is about to be completed, the electric push rod 3 is activated. The electric push rod 3 drives the filling tube 2 to move vertically upward. The return spring 7 relaxes, and the clamping block 5 slides relative to the filling tube 2 under the action of the return spring 7, driving the piston valve 6 to move. The piston valve 6 closes, and the filling tube 2 stops filling the pesticide into the bottle 12. The electric push rod 3 drives the filling tube 2 and the return spring 7 to move vertically upward. The clamping block 5 disengages from the bottle mouth of the pesticide bottle 12 and moves vertically upward with the filling tube 2 until the bottom of the filling tube 2 disengages from the pesticide bottle 12. The electric push rod 3 is then turned off, and the filling tube 2, clamping block 5, and return spring 7 stop moving.

[0024] like Figures 1-3 The bottom of the filling tube 2 shown is connected to a frustoconical filling head 8 extending vertically. The piston valve 6 is adapted to the filling head 8, and the piston valve 6 is provided with an infusion channel 601 connecting the upper and lower sides of the piston valve 6. The filling head 8 has a hollow structure.

[0025] Clamping block 5 drives piston valve 6 to slide inside the infusion tube and gradually move away from filling head 8. Pesticide in filling tube 2 passes through infusion channel 601 and enters filling head 8, filling bottle 12 with pesticide. After pesticide filling is almost complete, clamping block 5 drives piston valve 6 to slide inside the infusion tube until piston valve 6 and filling head 8 are tightly fitted, and pesticide is no longer introduced into filling head 8 from filling tube 2.

[0026] like Figures 1-3 The bottom of the piston valve 6 shown is provided with a cone 10 that is compatible with the filling head 8, and the height of the cone 10 is greater than the height of the filling head 8. A sealing ring is fitted on the cone 10.

[0027] The piston valve 6 and the filling head 8 fit tightly together. The bottom of the cone 10 passes through the filling head 8. The pesticide at the bottom of the filling head 8 gathers along the cone 10 and drips into the medicine bottle 12.

[0028] like Figures 1-3 The bottom of the clamping block 5 shown is provided with an anti-slip pad 9.

[0029] The clamping block 5 drives the anti-slip pad 9 to move downwards in the vertical direction until the anti-slip pad 9 and the mouth of the medicine bottle 12 are tightly fitted together.

[0030] like Figures 1-3 The anti-slip mat 9 shown has a vent hole 901, and the inside and outside of the medicine bottle 12 are connected through the vent hole 901.

[0031] The filling head 8 fills the pesticide into the medicine bottle 12, and the air in the medicine bottle 12 is discharged through the vent 901.

[0032] In actual use, the medicine bottle 12 is placed directly below the filling tube 2. The electric push rod 3 is activated, which drives the filling tube 2, clamping block 5, and return spring 7 to move vertically downwards until the bottom of the filling tube 2 passes through and enters the medicine bottle 12. The electric push rod 3 continues to drive the filling tube 2, clamping block 5, and return spring 7 to move vertically downwards. The clamping block 5 drives the anti-slip pad 9 to move vertically downwards until the anti-slip pad 9 and the mouth of the medicine bottle 12 are tightly fitted. The electric push rod 3 continues to drive the filling tube 2 to move vertically downwards. The clamping block 5 slides relative to the filling tube 2, the return spring 7 contracts, and the clamping block 5 drives the piston valve 6 to slide inside the infusion tube and gradually move away from the filling head 8. The piston valve 6 opens, the electric push rod 3 is closed, and the pesticide in the filling tube 2 passes through the infusion channel 601 into the filling head 8. The filling head 8 infuses the pesticide into the medicine bottle 12, and the air in the medicine bottle 12 is discharged through the vent hole 901.

[0033] After the pesticide filling is about to be completed, the electric push rod 3 is activated. The electric push rod 3 drives the filling tube 2 to move vertically upward. The return spring 7 relaxes, and the clamping block 5 slides relative to the filling tube 2 under the action of the return spring 7. The clamping block 5 drives the piston valve 6 to slide inside the filling tube until the piston valve 6 and the filling head 8 are tightly fitted. The piston valve 6 closes, and the filling tube 2 stops filling the pesticide into the bottle 12. The electric push rod 3 drives the filling tube 2 and the return spring 7 to move vertically upward. The clamping block 5 disengages from the mouth of the bottle 12 and moves vertically upward with the filling tube 2 until the bottom of the filling tube 2 disengages from the bottle 12. The electric push rod 3 is then turned off, and the filling tube 2, clamping block 5, and return spring 7 stop moving.
