Continuous pressing device for tree injection and infusion

Abstract

The invention discloses a continuous pressing device for tree injection and infusion. The continuous pressing device is characterized by comprising a probe and an air bag. A longitudinal air flue which extends from the rear end to the front end is arranged in the probe. A sharp protrusion is arranged at the front end of the probe. An air hole is formed in the portion, close to the sharp protrusion, of the side wall of the air flue. A boss which is gradually thickened backwards is arranged in the middle of the probe. The rear portion of the boss is provided with a compression nut which is matched with the probe through a thread, and the compression nut can abut against the rear end face of the boss. The rear end of the probe is connected with an air valve through a connector. An annular groove is formed in the outer end of the air valve. A binding strap for fixing a port of the air bag to the annular groove is arranged corresponding to the annular groove. Certain pressure is kept in a container bottle by means of high-pressure air in the air bag, so that the liquid medicine dripping speed is increased, and infusion requirements are met. The continuous pressing device can be recycled, and is simple in structure and obvious in effect.

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...

AI Technical Summary

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
