Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments, and the objects and effects of the present invention will become more apparent, and the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, the utility model discloses a manpower fertilizer placement drill includes inertia formula pick assembly, combined type pick handle, hose 10 and storage case 11, and the combined type pick handle includes hollow pipe 9 and sets up the sealed lid 13 in hollow pipe 9 one end, inertia formula pick assembly and hollow pipe 9 fixed connection of firing, and hose 10 one end is passed and is inserted sealed lid 13 and insert hollow pipe 9 in, the other end and storage case 11 intercommunication. Fertilizer box 11 is preferably a backpack.

The inertia firing type pickaxe assembly comprises a pickaxe shell 1, an inertia firing mechanism and an elastic valve 2, wherein the pickaxe shell 1 and the inertia firing mechanism are integrally arranged, the inertia firing mechanism comprises a piston 4 and a pressure spring 5 which are arranged in a piston cavity, and a fertilizer distributing chamber 14 is arranged in the pickaxe shell 1; one end of the fertilizer distributing chamber 14 is communicated with the hollow pipe 9 of the combined pick handle, the other end is a fertilizer outlet, and the opening and closing of the elastic valve 2 are controlled by the piston 4 for storing quantitative fertilizer. One end of the elastic valve 2 is fixed on the pick head shell 1 through a screw 3, the other end of the elastic valve seals the fertilizer distribution chamber 14 under the action of elasticity, and when the pick head of the manual fertilizer applicator is lifted up, the piston 4 can compress the pressure spring 5 under the action of inertia force to push the elastic valve 2 open so that the fertilizer in the fertilizer distribution chamber 14 is injected into the bottom of the hole.
