TECHNICAL SOLUTION

[0004] The technical problem to be solved by the utility model is to provide a soil deep fertilization device for tobacco planting, in order to solve the above technical problem, the technical scheme of the utility model is as follows:

[0005] A soil deep fertilization device for tobacco planting, including hand frame, drill rod and drill bit, the drill rod is fixedly connected to the bottom end of the hand frame, the drill bit is movably connected to the bottom end of the drill rod, the top end of the hand frame is fixedly connected with a connecting seat, a cavity is arranged in the connecting seat, a plug is movably connected in the cavity, the top end of the connecting seat is fixedly connected with a connecting pipe which is connected with the cavity, a through hole is arranged in the drill rod and connected with the cavity, a connecting groove is arranged in the inside of the top end of the drill bit and connected with the through hole, and fertilizer holes are arranged on both sides of the inside bottom end of the connecting groove.

[0006] Preferably, the plug is slidably connected in the cavity, a threaded rod is rotatably connected to one side of the plug through a rotating shaft, and one end of the threaded rod is threadedly connected through the connecting seat and extends to the outside of the connecting seat.

[0007] Preferably, sealing pads are fixedly connected to the upper and lower inner walls of the cavity, and the upper and lower plugs are in contact with the sealing pads, a liquid outlet hole is arranged in the inside of the plug, and the vertical center lines of the connecting pipe and the through hole are coincident.

[0008] Preferably, an annular groove is arranged in the inside of the drill rod close to the bottom end and on the outside of the through hole, and the upper end of the drill rod extends through and into the inside of the annular groove.

[0009] Preferably, a limiting plate is fixedly connected to the top end of the drill rod extending through the annular groove, and a spring is fixedly connected between the upper end of the limiting plate and the top end of the annular groove.

[0010] Preferably, a guide block is fixedly connected to the bottom of the connecting groove. The two sides of the guide block are inclined, and the lowest end of the guide block is connected to the fertilizer hole, which is inclined downward.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model involves moving the handheld frame to the desired fertilization position, connecting one end of the connecting pipe to the fertilizer bucket, and then rotating the threaded rod clockwise to connect the threaded rod to the connecting seat and rotate it to one side of the plug, thereby pushing the plug towards the connection pipe and the through hole and blocking the connection between the connection pipe and the through hole. Furthermore, the contact between the plug and the sealing gasket inside the cavity prevents liquid fertilizer from leaking out when not in use, thus avoiding waste.

[0013] 2. This utility model involves holding the handles at both ends of the handheld frame and rotating the handheld frame. At this time, the rotation of the handheld frame drives the drill rod and drill bit to rotate. The drill bit moves upward along the inside of the annular groove by squeezing into the ground, and compresses the spring, thereby moving the fertilizer hole to retract into the inside of the annular groove. This can prevent the soil from blocking the fertilizer hole during drilling, thus affecting the discharge of liquid fertilizer. When the drilling reaches a certain depth, the pressure applied to the rotation of the handheld frame is released. At this time, the spring inside the annular groove releases its elastic force and pushes the drill bit to move out of the outside of the annular groove, so that the fertilizer hole is exposed to the outside.

[0014] 3. This utility model uses the reverse rotation of the threaded rod to move the plug, thereby bringing the liquid outlet on one side of the plug and the connecting pipe and through hole to the same central axis. Then, the liquid fertilizer passes through the liquid outlet and through hole in sequence and enters the interior of the connecting groove. Finally, after being guided by the inclined downward guide block, it flows out from the fertilizer holes on both sides and fertilizes the deep soil layers. Attached Figure Description
