Pouring spraying head for greenhouse

The invention relates to a pouring spraying head for a greenhouse. The pouring spraying head structurally comprises a front wheel, a rear wheel and a support. The front wheel and the rear wheel are connected to the front end and the rear end of the support respectively, and the rear end of the support is further connected with a push handle; an irrigation and sowing mechanism is further arranged at the position, between the front wheel and the rear wheel, of the support and comprises a liquid irrigation layer on the upper layer and a sowing layer on the lower layer; the liquid irrigation layer comprises a liquid storage tank, a liquid storage tank cover, a liquid pumping pump, a spraying head and a liquid outlet pipe; and one end of the liquid outlet pipe is connected with the spraying head, and the other end of the liquid outlet pipe penetrates the liquid storage box cover to stretch into the interior of the liquid storage tank so as to be connected with the liquid drawing pump. According to the pouring spraying head, in the advancing process, sowing work can be automatically completed, and the working efficiency of the spraying head is improved; through rotary spraying, the spraying range of the pouring spraying head is widened, the practical performance is improved, and the pouring spraying head of the design further has the beneficial effects of being simple in structure, easy to manufacture, practical and efficient.
