The power shaft 62 rotates to drive the stirring frame 61 and further stir the liquid in the barrel, and in the stirring process, the power shaft 62 drives the stirring frame 63 to rotate so as to drive the stirring rod 64 to rotate; the poking piece 451 is poked once when the poking rod 64 rotates for one circle; when the shifting piece 451 is shifted, the steel wire rope 3 is wound up by the winding wheel 45, so that the upper ends of the limiting rods are mutually close to each other, and the rubber barrel wall 51 is further inwards gathered; after toggle lever 64 leaves toggle piece 451, rubber barrel wall 51 expands outward again under the weight of the water inside it. Therefore, in the stirring process, the rubber barrel wall performs the periodic inward contraction → outward expansion action, and the liquid in the barrel body 5 is shaken by the periodic inward contraction → outward expansion action, so that the fertilizer dissolving effect is improved by matching with the stirring action; also beneficial to the uniform distribution of small-particle fertilizers in water, avoiding sedimentation and further beneficial to the uniformity of fertilization.
As shown in fig. 3 and 4, the barrel 5 further includes a plurality of rubber strips 53 extending along a generatrix of the rubber barrel wall 51 at the outer side of the rubber barrel wall 51, each rubber strip 53 being distributed around the rubber barrel wall 51, the rubber strips being fixedly connected to the rubber barrel wall 51. The rubber strip and the rubber barrel wall can adopt an integrated structure. The rubber strip 53 can enhance the supporting performance of the rubber barrel wall 51, prevent the rubber barrel wall 51 from collapsing under the self weight, and the rubber strip 53 can also enhance the elastic coefficient of the rubber barrel wall 51, so that the rubber barrel wall 51 can rebound under the self elasticity after being retracted.
The second embodiment:
in the second embodiment, the base is different from the first embodiment in the aspect, and the other aspects are the same except for the base.
As shown in fig. 10, a mounting opening 47 is provided on the base 4, a vibration box 8 is provided in the mounting opening 47, a plurality of supporting springs 81 are provided at the bottom of the vibration box 8, a vibration generator 82 is provided in the vibration box 8, and the upper side of the vibration box 8 is disposed toward the rubber barrel bottom 52. After the vibration generator 82 is started, the vibration box 8 vibrates, so that the rubber barrel bottom 52 vibrates, the vibrating rubber barrel bottom, the periodic inward contraction → the outward expansion rubber barrel wall and the stirring effect are matched with each other, the fertilizer dissolving speed can be greatly improved, the problem of sedimentation can be thoroughly avoided for suspension type fertilizers, and the uniformity of fertilizer liquid is ensured.
