Description

Technical Field

[0001] The utility model relates to the technical field of gardening equipment, in particular to an infusion device for tree injection. Background Art

[0002] A search revealed prior art patent number CN105075697A, which outlines the following: a continuous pressure-applying device for tree injection and infusion, characterized by comprising a probe and an airbag. The probe comprises a longitudinal airway extending from the rear end to the front end, a sharp protrusion at the front end of the probe, and a vent hole on the sidewall of the airway near the sharp protrusion. The probe comprises a boss that gradually thickens toward the rear, and a compression nut that threads onto the rear end of the boss and is secured to the rear end of the boss. The rear end of the probe is connected to an air valve via a joint, and an annular groove is formed at the outer end of the valve. A restraining strap corresponding to the groove secures the airbag port to the groove. While continuous pressure injection is possible, its structure is relatively complex, requiring the airbag to be pressed to achieve pressurization. Furthermore, the internal pressure regulation is not constant. For example, after the initial atmospheric pressure is reached, the internal pressure is relatively high, which can easily lead to leakage of the drug from the tree trunk during the initial injection phase. Utility Model Content

[0003] The purpose of the present utility model is to provide an infusion device for tree injection, so as to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an infusion device for tree injection, comprising a medicine bottle for containing medicine; one end of the medicine bottle is connected to an end cap, and the other end of the medicine bottle is also provided with a liquid outlet; a piston is provided inside the medicine bottle, and a counterweight block is placed on the piston to promote the smooth flow of medicine out of the medicine bottle.

[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0020] See also Figure 1-5 The utility model provides an embodiment: an infusion device for tree injection, comprising a medicine bottle 1 for containing medicine; one end of the medicine bottle 1 is connected to an end cap 3, and the other end of the medicine bottle 1 is also provided with a liquid outlet 6; a piston 7 is provided inside the medicine bottle 1, and a counterweight block 9 is placed on the piston 7 to promote the smooth flow of medicine out of the medicine bottle 1.

[0021] In summary, since the counterweight 9 is placed on the piston 7, a certain pressure can be maintained in the medicine bottle 1, thereby increasing the dripping speed of the medicine solution and meeting the infusion needs. In addition, the equipment can be recycled and has a simple structure. It can reduce the injection cost of trees without affecting the injection of the medicine. At the same time, since the weight of the counterweight 9 is constant, the outflow pressure of the medicine is constant, which can reduce the leakage of the medicine. Secondly, by selecting counterweights 9 of different weights, the outflow pressure of the medicine can be adjusted.

[0022] Furthermore, since there are multiple counterweights 9 and each of the counterweights 9 has the same mass, the number of counterweights 9 can be accumulated, so that the device can increase the pressure inside the medicine bottle 1 by increasing the number of counterweights 9. In particular, the mass of the counterweights 9 is equal, so that the pressure inside the medicine bottle 1 can be precisely controlled; secondly, the pressure value inside the medicine bottle 1 can be preliminarily understood by the number of counterweights 9.

[0023] Furthermore, since one side of the counterweight 9 is provided with a slot 10 and the other side of the counterweight 9 is provided with a latch 11, the two counterweights 9 can be reliably stacked vertically on the piston 7 when combined to prevent the counterweights 9 from collapsing during the stacking process. At the same time, the side of the piston 7 facing the counterweight 9 is also provided with a mounting groove 12. The mounting groove 12 can also be used to ensure the stability of the counterweights 9 after stacking. At the same time, the provision of the mounting groove 12 makes the central axis of the multiple counterweights 9 coincide with the central axis of the piston 7, so as to ensure that the piston 7 is evenly stressed.

[0024] On the basis of the above scheme, after the end cap 3 is connected to the upper end of the medicine bottle 1, the provided sealing gasket 8 is fixed to the top of the medicine bottle 1. Specifically, the end cap 3 is threadedly connected to the upper end of the medicine bottle 1, and a through hole 5 is also provided in the middle of the end cap 3. Based on this, when the medicine bottle 1 is transported, the end cap 3 is threadedly matched with the end of the medicine bottle 1 to fix the sealing gasket 8 on the top of the medicine bottle 1, thereby preventing the piston 7 and the medicine flow channel located below the piston 7 from being outside the medicine bottle 1; at the same time, when in use, the sealing gasket 8 is removed, and then the counterweight 9 is placed on the piston 7 through the through hole 5. Therefore, at this time, the through hole 5 is convenient for the placement of the counterweight 9 while balancing the air pressure.

[0025] To facilitate connection between medicine bottle 1 and the tree trunk, the bottle 1 is secured to the tree trunk via a base 2 formed on its outer wall. Both ends of the base 2 are provided with harness holes 4. Thus, one end of a tie strap is connected to the harness hole 4 at one end of the base 1, and the other end of the tie strap is then passed around the tree trunk and connected to the harness hole 4 at the other end of the base 2, thereby securing the bottle 1 to the tree trunk. The tie strap is preferably a flat elastic band.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
