Description

Pulsation and vibration reduction device for agricultural water supply or mixed solution supply facilities}

The present invention relates to a device for reducing pulsation and vibration of agricultural water or mixed solution supply equipment. More specifically, it relates to a device for reducing vibration and pulsation caused by a high-pressure pump that supplies clean water or mixed solution to the injection unit, thereby reducing the constant or This relates to a pulsation and vibration reduction device for agricultural water supply or mixed solution supply equipment that can prevent loosening, damage, and reduced lifespan of mechanical elements provided in the mixed solution supply equipment.

The mixed solution, which is generally manufactured by mixing water used in agriculture with chemicals for various purposes such as plant growth, odor reduction and disinfection in livestock houses, controls diseases, pests, and weeds that occur during cultivation and storage of crops. , It is used for the purpose of promoting and suppressing the physiological functions of crops and as an auxiliary medicine used to improve livestock farms and rural environments.

Meanwhile, these mixed solutions are manufactured by putting chemicals and water in a mixing tank and stirring them. To mass-produce the mixed solutions, a large amount of chemicals and water are put into a large mixing tank at a certain ratio, and the added materials are quickly and uniformly stirred. This is important. In the past, there was no separate means for uniformly and quickly mixing a large amount of mixed materials. As a result, the mixing time of the mixed solution was delayed, which resulted in a decrease in productivity and a problem in that the quality of the mixed solution deteriorated.

In addition, in the mixing of chemical and water using the conventional method as described above, the chemical and water are simply mixed by the user before work and sprayed on crops and livestock sheds, so mixing is not done properly or the chemical components precipitate over time. Due to this phenomenon, it was difficult to spray the mixture uniformly throughout the crops and livestock sheds.

In addition, since a large-capacity mixing tank is carried in the loading box of the transportation means, the remaining mixed liquid overflows during operation and if the water runs out, new water must be collected and transported. This reduces the effectiveness of the loading container, so it must be packed with other items together. There is a problem that it cannot be transported, and for example, technology such as Korea Patent Publication No. 10-2011-0012857 “Device for mixing fertilizer and pesticide ingredients” has been developed.

Meanwhile, technologies such as Korean Patent No. 10-1290781 “Chemical solution mixing device for pesticide sprayer” have been developed to supply the mixed solution produced from the mixing tank directly to the farm, but this simply involves manufacturing pesticide and then spraying it on crops.

Specifically, vibration occurs in the piping system due to various causes. Even if such vibration occurs inside the piping, there is no major problem with the stability of the piping system because the rigidity of the piping system is relatively high. However, the vibration frequency acting on the piping and the piping system itself are not affected. If the natural frequencies match, a resonance phenomenon occurs, resulting in amplified vibration that is much larger than the original vibration, greatly damaging the stability of the piping system.

In order to reduce the vibration that occurs in these cases, it is necessary to redesign the pipe through analysis of the natural frequency of the pipe or change the position of the pipe support device through analysis of the mode shape of the vibration. However, it must be immediately input when carrying out farming. Redesigning and replacing piping for agricultural water supply or mixed solution supply facilities involves a lot of time and cost, and changing the location of piping support devices has limitations in reducing vibration, so development of a device that can reduce excessive vibration in this resonance state This is necessary, and there is an urgent need to develop technology for pulsation and vibration reduction devices for agricultural water supply or mixed solution supply equipment that can prevent the lifespan of the supply equipment and mechanical components for mixing and supplying the mixed solution.

At this time, flow holes 51210 may be provided in the plurality of partition walls 5121 at positions opposite to each other.

More specifically, to describe the preferred location of the air flow hole 51210 with reference to FIG. 13, first, when one partition wall 5121 is provided at the rearmost part of the supply hose 510, the flow hole provided at this time ( 51210 is provided at the top of the partition wall 5121, and the flow hole 51210 of the partition wall 5121 provided in front of the rearmost partition wall 5121 is the flow hole ( 51210), it is provided in the opposite position, that is, at the bottom.

Through this, the pulsation reduction means 512 according to an embodiment of the present invention does not cause the constant water or mixed solution supplied at high pressure through the pump unit 40 to go straight in the direction of the injection unit 50, but rather to the shock prevention unit. The inside of the supply hose 510 can flow sequentially through the flow hole 51210 provided in the partition wall 5121 forming 320.

Accordingly, the pulsation reduction means 512 according to an embodiment of the present invention uses constant water or mixed liquid supplied at a pressure exceeding the allowable value through a combination of a partition 5121 provided therein and a flow hole 51210 provided therein. It is possible to prevent problems caused by pulsation shocks acting on the injection unit 50 or the supply hose 510.
