Abstract
The utility model discloses a powdery medicament airflow precision conveying device of a plant protection machine, which comprises an air pipe and a material pipe; the air pipe is horizontally arranged, one end of the air pipe is an air inlet, and the other end of the air pipe is an air outlet; the material pipe penetrates through the upper side wall of the air pipe and is fixedly connected with the upper side wall of the air pipe; the material pipe is obliquely arranged, and the upper end of the material pipe is inclined towards one side where the air inlet is located; the lower end of the side wall of the material pipe close to one side of the air inlet extends into the inner cavity of the air pipe; the further improvement lies in that: the inner wall of the air pipe between the material pipe and the air inlet of the air pipe is provided with an axial spiral groove. The utility model discloses carry the precision height, carry the distance long, carry evenly.
Description
Technical Field
The utility model relates to an agricultural machine technical field especially relates to a plant protection machine medicament conveyor.
Background
The plant protection machine is equipped with medicament conveyor, and current medicament conveyor generally includes tuber pipe, material pipe, and the tuber pipe is put flat, and one end is the air intake, and the other end is the air outlet, and the material pipe link up the tuber pipe on the lateral wall to with tuber pipe side wall fixed connection, material pipe put to one side, the upper end is to the one side slope at air intake place. During the use, likepowder medicament falls from the material pipe, from the air intake air, will blow off from the air outlet from the likepowder medicament of material pipe whereabouts, accomplishes and spouts the medicine operation. The drawbacks of such a medicament delivery device are: the air pipe blows to the air outlet from the air inlet in-process, has partial wind to blow from material pipe lower extreme upwards, and the one hand forms the resistance to the whereabouts of likepowder medicament, influences likepowder medicament volume of falling to influence medicament transport accuracy, on the other hand, the reposition of redundant personnel amount of wind reduces air velocity, and transport distance is short.
Disclosure of Invention
The utility model provides a plant protection machine powder medicament air current precision conveyor that can show improvement medicament transport precision and transport distance to the not enough of prior art.
The utility model discloses a technical goal is realized to following technical scheme.
The airflow precise conveying device for the powdery medicament of the plant protection machine comprises an air pipe and a material pipe; the air pipe is horizontally arranged, one end of the air pipe is an air inlet, and the other end of the air pipe is an air outlet; the material pipe penetrates through the upper side wall of the air pipe and is fixedly connected with the upper side wall of the air pipe; the material pipe is obliquely arranged, and the upper end of the material pipe is inclined towards one side where the air inlet is located; the improvement is that: the lower end of the side wall of the material pipe close to one side of the air inlet extends into the inner cavity of the air pipe.
Preferably, an axial spiral groove is formed in the inner wall of the air pipe between the material pipe and the air inlet of the air pipe.
Compared with the prior art, the utility model, following positive effect has:
1. the lower end of the side wall of the material pipe, which is close to one side of the air inlet, extends into the inner cavity of the air pipe, so that the lower end of the side wall of the material pipe, which extends into the inner cavity of the air pipe, shields part of the ventilation section to form a closed opening. When air is blown from the air inlet to the air outlet, the air speed after closing up is obviously enhanced, on one hand, the conveying speed is obviously improved, and the conveying distance is obviously increased; on the other hand, in the air pipe inner chamber at the lower end of the material pipe, a space which is not shielded by the side wall of the material pipe and is shielded by the side wall of the material pipe forms a large pressure difference, a siphonage phenomenon is formed, no air blows upwards from the lower end of the material pipe, and powdery medicament can be attracted to fall down, so that the medicament conveying precision is obviously improved.
2. The inner wall of the air pipe between the material pipe and the air inlet of the air pipe is provided with an axial spiral groove, when air is blown from the air inlet to the air outlet, a spiral air belt is formed, the air speed is increased, on one hand, the conveying uniformity is obviously improved, and on the other hand, the conveying distance is further increased.
