Continuous pressure device for tree injection and transfusion

Abstract

The invention discloses a continuous pressure device for tree injection and transfusion, which is characterized in that it comprises a probe and an air bag, the probe is provided with a longitudinal airway extending from the rear end to the front end, and the front end of the probe has a sharp protrusion. There are ventilation holes on the side wall of the sharply protruding airway, the middle part of the probe is provided with a boss that gradually becomes thicker backwards, and the rear of the boss is provided with a screw thread that fits on the probe and can stop on the rear end of the boss. The compression nut on the top, the rear end of the probe is connected to the air valve through the joint, the outer end of the air valve is provided with an annular groove, and the corresponding annular groove is provided with a restraint belt that fixes the port of the airbag in the annular groove; the present invention passes the high-pressure air in the airbag , to maintain a certain pressure in the container bottle, thereby increasing the dripping speed of the medicinal solution and meeting the needs of infusion. The device can be recycled, and the structure is simple and the effect is obvious.

Description

technical field [0001] The invention relates to a device for transfusion in the field of tree and plant protection, in particular to a continuous pressure device for tree injection and transfusion. Background technique [0002] Our country is a large forestry country, and fruit trees are widely planted. With the improvement of planting technology, when the seedlings are transplanted or in their critical growth period or when diseases occur, in order to make the trees grow healthily, it is often necessary to infuse them to provide them with the necessary water, nutrients or Drugs, thereby greatly improving the survival rate and growth trend of trees, have obvious effects on increasing production and increasing efficiency, especially the cultivation of some trees with high economic value is inseparable from infusion maintenance, so infusion technology is especially important. Existing tree infusion is also the same as human infusion. The nutrient solution or medicinal solution...

Problems solved by technology

When the amount of infusion is not large, the tip of the vial is often used for direct instillation. Since the absorption of trees is a slow process, it is required not to inject quickly at one time, and people cannot always hold the liquid during this process, so they can only pour the vial down. Put it at the infusion position and allow it to infuse by itself. Due to the relatively dense vacuum in the vial and the dense tissue in the tree, the liquid in the vial sometimes flows out at a slower rate than the tree absorbs it. Reduced drug efficacy, which still needs to be solved by technology
