[0037] In the embodiment, please refer to Figure 3 The gas control assembly 24 includes a hydraulic cylinder 241, a connecting seat 242, an air inlet control column 243 and an air suction control column 244, the hydraulic cylinder 241 is arranged in the hydraulic cavity 21, and the telescopic end is arranged downward and connected with the connecting seat 242, one end of the air inlet control column 243 and the air suction control column 244 is connected with the lower end of the connecting seat 242, and the other end is respectively slid in the air inlet pipeline 22 and the air suction pipeline 23; in the specific operation, the connecting seat 242 is driven to slide upward by the hydraulic cylinder 241, so as to drive the air inlet control column 243 and the air suction control column 244 to slide in the air inlet pipeline 22 and the air suction pipeline 23 respectively, the air inlet control column 243 can open one or more air inlet holes 221 in the sliding process, so as to improve the input rate of ethylene in the ripening box 1; and the air suction control column 244 can seal the air suction hole 231 at this time, so as to avoid the ethylene leakage in the ripening box 1, the two are synchronous, the structure is optimized, and the intelligent operation is improved.

[0038] Specifically, the air suction control column 244 comprises a connecting part 2441 and a closing part 2442, the diameters of the air suction control column 244 and the closing part 2442 are the same as the inner diameters of the air inlet pipe 22 and the air suction pipe 23 respectively, and the diameter of the connecting part 2441 is smaller than the inner diameter of the air suction pipe 23; the air suction hole 231 can be closed by the closing part 2442 during the sliding process of the air suction control column 244; a plurality of air guide holes 4 are arranged on the closing part 2442; the air guide holes 4 play a role of connecting the ripening box 1 and the air suction hole 231, that is, when it is needed to reduce the ethylene content in the ripening box 1, the connecting seat 242 is driven to slide downward by the hydraulic cylinder 241, at this time, the air inlet control column 243 closes the air inlet hole 221, at this time, the closing part 2442 slides away from the air suction hole 231, so that the air guide hole 4 is connected with the air suction hole 231, and then the excessive ethylene is absorbed and removed by the external air suction source.

[0040] In addition, please refer to the back Figure 2 A plurality of air inlet branch pipes 100 and air suction branch pipes 200 are respectively connected between the air inlet pipe 22 and the air suction pipe 23 and the ripening box 1, and the air inlet branch pipe 100 is provided with a nozzle 7 at the end; the nozzle 7 plays a role of improving the transportation efficiency of ethylene, and can facilitate the uniform distribution of ethylene in the ripening box 1, avoid the existence of dead angle or corner with less ethylene content, and homogenize the ripening rate and effect of the whole fruits in the ripening box 1, so as to avoid that part of the fruits ripen too fast or too slow and affect the overall fruit ripening effect.

[0041] Specifically, please refer to Figure 4The nozzle 7 comprises a connecting piece 71, a shell 72, an end piece 73, a pressure spring 74 and a resisting plate 75. The connecting piece 71 is arranged between and threadedly connected with the shell 72 and the air inlet branch pipe 100. The shell 72 is internally provided with a limiting ring 721.

A placing groove 112 is recessed in each of the accommodation cavities 111. A substrate 113 for placing persimmons is embedded in the placing groove 112. A weight sensor (not shown in the figure) is arranged on the substrate 113. In specific operation, how to determine whether the fruit is ripe can be determined by measuring the weight change of the fruit by using the weight sensor. That is, the water content, sugar content, density of the flesh and the like of the persimmon change during the ripening process, which finally causes the weight of the persimmon to change. In the stage of unripe persimmons, the persimmons contain more starch and less sugar, the flesh is relatively hard, the water content is relatively low, and the weight is small. With ripening, the starch in the persimmons gradually converts into sugar, the flesh begins to soften, the water content increases, and the weight of the persimmons increases. Finally, whether the fruit is ripe or not can be determined by the weight change ratio.

[0043] Specifically, an elastic pad 8 is arranged on the placing groove 112. The elastic pad 8 can improve the accuracy of the fruit weight measurement. The structure of the oxygen generating mechanism 3 is the same as that of the ethylene generating mechanism 2. The steps for measuring the ethylene content are used to measure the oxygen content in the ripening box 1. Maintaining the oxygen content in the ripening box 1 can improve the ripening efficiency and the taste of the fruit.

[0045] The ethylene control sensor and the oxygen control sensor are respectively used for monitoring the ethylene and oxygen content in the ripening box 1, so as to control the two in the ripening box 1 at an ideal level by using the ethylene generating mechanism 2 and the oxygen generating mechanism 3 respectively.

[0046] The temperature sensor and the humidity sensor are used for monitoring the temperature and humidity in the ripening box 1, so as to make the fruits in a more ideal state for ripening operation; when the temperature and humidity in the ripening box 1 do not meet the setting, the alarm is reminded, so as to adjust the related indexes in the ripening box 1, and the temperature and humidity adjustment is a conventional technical means, which will not be described here.

[0047] The weight change ratio of persimmons is set in the electric control system, and when the weight sensor measures the weight change, the alarm is reminded.

[0048] The gas control assembly 24 of the ethylene generating mechanism 2 can control the ethylene content in the ripening box 1, so as to avoid that part of the fruits mature too fast or too slow and affect the overall fruit ripening effect; meanwhile, the oxygen generating mechanism 3 set can control the oxygen content in the ripening box 1, stimulate the respiration of the fruits and improve the respiration efficiency to realize the consistent maturity degree of the fruits, improve the water content and sugar content of the fruits, improve the taste of the fruits, so as to achieve the ripening purpose and improve the work efficiency.
