Utility Model Content
[0005] The purpose of this invention is to provide a pesticide production dispensing and filtration device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pesticide production dispensing and filtering device, comprising a filter cylinder and a connecting mechanism. A support block is fixedly connected to the inner wall of the filter cylinder, and a filter screen overlaps the top of the support block. The connecting mechanism includes a connecting pipe fixedly passing through both sides of the filter screen. A connecting rod is slidably installed inside the connecting pipe. A spring is sleeved on the upper end of the connecting rod. Two grooves are symmetrically opened at the lower end of the connecting rod. A guide groove is opened on the inner wall of each groove. A guide block is slidably connected inside the guide groove. A snap-fit block is fixedly connected between the two guide blocks. A connecting hole is opened inside the support block, and snap-fit grooves are opened on both sides of the inner wall of the connecting hole.
[0007] In a preferred embodiment, the end of the snap-fit block away from the groove is provided with an angle.
[0008] In a preferred embodiment, a detachable tie rod is fixedly installed between the upper ends of the two connecting rods.
[0009] In a preferred embodiment, the top of the filter cartridge is provided with a cartridge cover, and through holes are provided on both sides of the cartridge cover. The connecting pipe slides through the through holes, and a limit plate is provided on the surface of the connecting pipe below the cartridge cover.
[0010] In a preferred embodiment, the cylinder cover is provided with a feed pipe.
[0011] In a preferred embodiment, the bottom of the filter cylinder is provided with a discharge pipe.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This pesticide production dispensing and filtration device, through its connecting mechanism, allows for easy filter screen installation. Simply hold the pull rod and slowly insert the filter screen into the filter cylinder, simultaneously aligning the lower end of the connecting tube with the connecting hole of the support block and inserting it. Place the filter screen on the support block. Because the end of the locking block furthest from the groove is angled, it is compressed and retracts into the connecting tube when it contacts the support block. Simultaneously, the spring is compressed. Once the locking block aligns with the locking groove, the spring releases its elasticity, causing the connecting rod to slide down. This causes the connecting rod to slide the guide block along the guide groove, which in turn inserts the locking block into the locking groove, securing the connecting tube and thus installing the filter screen. When the filter screen needs to be removed, simply pull the pull rod, causing it to slide the connecting rod upwards, allowing the locking block to be pulled out of the locking groove. Continuing to pull the pull rod allows the connecting tube and filter screen to be removed together, facilitating filter screen removal and improving cleaning efficiency.
[0014] This pesticide production dispensing and filtration device, by setting through holes and limiting plates, allows the cylinder cover to open together with the filter screen when the connecting pipe is pulled upward during the disassembly process. When it is necessary to open the cylinder cover separately, the pull rod can be removed first, and then the cylinder cover can be slid out from the top of the connecting pipe, increasing the degree of freedom.
