Abstract

Disclosed is an automatic irrigation and dust-washing machine which automatically performs irrigation when the soil turns dry and automatically sprays water to wash away dust when the dust becomes thick. The humidity of soil and the thickness of dust covering flowers and trees are detected at regular intervals; if the humidity of soil or the thickness of dust exceeds the set value (the soil is too dry or the dust is too thick), an electromagnetic valve (or a pump) is started up to spray water for irrigation and dust washing, and the water spraying stops when the prolonged time for water spraying (hereinafter referred to as discharge time, which is set according to the actual situation) is up. The water spraying time is delivered with a design of double time control (namely double insurance) so as to completely eradicate the accident that the water flow can not be stopped due to machine faults. After the humidity of the soil is set, perennial management is unnecessary, and the machine can automatically regulate and control the wetness of the soil: the temperature in summer is high and the water in leaves vapor quickly, so the wetness of the soil increases; on the contrary, the wetness of the soil is reduced in winter, thereby ensuring that the flowers and trees grow well and are clean without dust. The automatic irrigation and dust-washing machine of the invention is characterized by full automation, simple use and management, low power consumption, water saving, labor saving and expenditure reduction and ensures landscaping and flower and tree management to progress towards modernization gradually.

Example Embodiment

[0036] In Figure 1, the voltage required for the two detection probes is lower. In order to save energy, 9V DC is used. Timers A1, A3, and A4 all use 555 time base circuits, and voltage comparators A2 and A5 use 3140 integrated blocks. In this way, the types of integrated blocks are reduced and maintenance is facilitated. There are indicator lights at each important working stage, which is convenient for management and use, and it is also convenient for maintenance and judgment of faults. The temporary detection button ST1 is set to facilitate the adjustment of the dust thickness setting, soil dry and wet setting and water spray time setting.
[0037] in figure 2 Among them, the soil dryness and wetness detection probe is too large to be easily placed in the bonsai; too small, it is easy to cause poor contact with the soil. It is more appropriate for the two electrodes to be 50×30×2mm in size, and they are bonded on both sides of the plastic insulating board. When installing, choose a representative place and place the probe below 50mm on the mud surface.
[0038] in image 3 In the middle, the infrared light emitting diode ⑥ and the infrared receiving diode ① and ④ are arranged in a triangle, the axes of ① and ④ are aligned with ⑥ respectively, but the axis of ⑥ is close to ① between ① and ④. Properly adjust the deflection angle so that the voltage drop of ① when there is no dust on the film ③ is about the total voltage /4, which can be adjusted between 2 and 2.5V. The advantages of the film ③ folded into a V shape according to the figure are: ① The infrared light emitted by ⑥ is received through two layers of dust, which improves the detection sensitivity; when spraying water, the dust on the surface of the film is easy to clean, and the detection accuracy is improved.
[0039]During installation, the dust thickness detection probe is placed in a representative position in the green belt. The thickness of the dust on the probe film cannot be equal to the thickness of the dust on the branches and leaves of flowers and trees, and the thickness of the dust on the branches and leaves cannot be completely equal. Therefore, the dust thickness setting is based on the actual situation and people's viewing requirements, and is set by intuitive feeling. Therefore Figure 4 The number on the middle dust thickness setting dial does not directly represent the dust thickness or the voltage reference value, but it is convenient to determine the position when it is rotated.
[0040] in Figure 4 In, the water spray time A and B are set. The time set for both should be the same, otherwise, the actual water spray time is subject to the shortest time.
[0041] The number on the soil dry and wet setting dial does not directly represent the water content or voltage reference value. One is because the water content of the same piece of land is not necessarily the same; the other is because the electrical conductivity of the soil is not only related to the water content, but also related to the soil structure, that is, the voltage drops detected by different soils with the same water content are different ; The third is that the majority of flower and tree managers at the front line do not know (nor need to know) the minimum water content of a flower and tree that grows well here. It is based on practical experience to determine how dry the flower and tree in this place should be watered and determine the twist position.
[0042] Water source: (1) Water is taken from ponds, streams, and rivers. The solenoid valve is replaced by a water pump. Figure 4 The "connect solenoid valve switch" is connected in series with an AC contactor between the terminals. (2) Tap water. The solenoid valve switch is directly connected to the tap water pipe. If the tap water pressure is not high and the spray effect is poor, connect the water pump after the solenoid valve to pressurize. The water pump wiring is the same as (1), and the solenoid valve wiring is connected in parallel with the water pump. The above two are determined according to their actual situation.
[0043] Sprinkler heads: There are many forms on the market, which should be selected according to their actual conditions, such as the width of the ground, the types of flowers and trees, and the number of nozzles installed, so as to achieve full pouring, pouring, and dust flushing, saving water and no damage Tileable.
[0044] The ground controlled by a machine should not be too large, because the soil thickness varies greatly between the wet and dry soil and the surrounding dust, which is not conducive to the setting of the soil dry and wet and the dust thickness. It should be determined according to their actual conditions.
[0045] In summary, the installation of the machine and sprinkler system should be done by an installation company (team) with a long history. The establishment of a "sprinkler irrigation and dust cleaning installation company (team)" to engage in the installation of the "automatic irrigation and dust cleaning" project will be able to maximize the benefits of the automatic irrigation and dust cleaning machine.
