The utility model relates to the technical field of plastic bags, and provides a full-automatic plastic bag sealing and cutting machine which comprises a machine table, a plurality of feeding plates are installed at the top of the machine table, feeding shafts are installed on the side faces of the feeding plates, and a transmission assembly is arranged on the portion, on one side of each feeding shaft, of the machine table. A plurality of cutting tables are installed at the top of the machine table, cutting grooves are formed in the tops of the cutting tables, cutters are arranged above the cutting grooves, the tops of the cutters are movably connected with the bottom of a lifting plate, the upper end of a heat sealing machine is installed at the position, on one side of the cutters, of the bottom of the lifting plate, and the lower end of the heat sealing machine is installed at the tops of the cutting tables. The top of the lifting plate is connected with the telescopic end of the lifting cylinder. By means of the technical scheme, the technical problem that in the prior art, when a plastic bag is cut, a heat sealing cutter cannot be buffered is solved.

This utility model relates to the field of agricultural drainage technology, specifically to an agricultural drainage ditch for rural water utilization. It includes a first drainage ditch, a second drainage ditch, and a fixing component. One end of the first drainage ditch is spliced ​​with the second drainage ditch, such that the groove at the end of the second drainage ditch corresponds to the protrusion at the end of the first drainage ditch. During the splicing process, the insertion component at the end of the second drainage ditch is inserted into the limiting component at the end of the first drainage ditch to fix the joint between the first and second drainage ditches. This helps prevent people from passing through and stepping on the ditch, or heavy objects from being placed on a certain splicing section of the ditch. When the ditch is subjected to external force, relative displacement can easily occur between the spliced ​​sections. Although the sealant has certain adhesive and sealing properties, its resistance to external forces is limited. Over time, this can easily lead to damage to the internal structure of the sealant, resulting in cracks or even separation from the surface of the ditch, thus causing leakage.
