This utility model relates to the field of leek baling technology and discloses a leek harvesting and baling machine, including a machine housing with a baling mechanism fixed on the housing; and a clamping assembly disposed on the machine housing, including a clamping member, the clamping member including a clamping plate located on the machine housing, the clamping plate having a through groove, a fixed shaft inserted into the through groove, and a rotating plate fixed to one side of the clamping plate. The beneficial effects of this utility model are: by setting up a leek clamping device, leeks can be directly placed between two clamping plates. Simply pressing a button allows the clamping plates to automatically approach and pre-clamp the leeks, replacing the tedious manual gathering operation. Simultaneously, the pre-clamping effect of the clamping plates increases the force-bearing area of ​​the leeks, evenly distributing the pressure on the leek surface, avoiding damage caused by excessive instantaneous pressure on a localized area, thereby improving the efficiency of the baling operation and maintaining the integrity and freshness of the leeks.

This utility model discloses a California bass farming pond, relating to the field of bass farming technology. The California bass farming pond includes a holding tank, a filter assembly, and a harvesting assembly. A connecting box is fixedly connected inside the holding tank. The bottom of the holding tank is hollow. The filter assembly and the harvesting assembly are located on the holding tank. The harvesting assembly includes an auxiliary rod, a threaded rod, a bending plate, a motor, and an arc-shaped plate. The threaded rod is rotatably installed on the inner bottom of the connecting box, and the auxiliary rod is fixedly connected to the inner bottom of the connecting box. This utility model can separate large and small fish and facilitate their harvesting. By separating large and small fish, it provides suitable space and environment for fish of different sizes, improving the growth rate and health of the fish, avoiding resource competition and pressure caused by size differences, and the structure facilitates harvesting, making operations more convenient and faster when pond management or harvesting is required.
