Detailed implementation manners
[0032] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but not to limit the present invention.
[0033] A fumigation device for automatically fumigating fruits with methyl bromide gas, as Figure 1 and Figure 2 shown, includes a fumigation box body 1, a cover plate 2, an air inlet assembly 3, a handle 4, a locking mechanism 5 and an exhaust mechanism 6. The cover plate 2 is rotatably connected to the front side of the right part of the fumigation box body 1. The air inlet assembly 3 is connected to the right side of the fumigation box body 1. The air inlet assembly 3 includes an air pump and an air inlet pipe. The air inlet pipe is connected to the right side of the fumigation box body 1, and an air pump is installed in the air inlet pipe. The handle 4 is connected to the right side of the cover plate 2. The locking mechanism 5 is provided on the cover plate 2. The exhaust mechanism 6 is provided inside the fumigation box body 1.
[0034] It should be noted that in order to avoid a large amount of harmful substances on the fruit surface, this device can be used to fumigate the fruit with methyl bromide gas. First, turn the cover plate 2 to the right to open it through the handle 4, then place the fruit at the bottom inside the fumigation box body 1, and then close the cover plate 2. At the same time, lock the cover plate 2 through the locking mechanism 5. Immediately afterwards, input methyl bromide through the air inlet assembly 3 to start fumigating the fruit. During the treatment process, the internal gas is circulated through the exhaust mechanism 6 to improve the fumigation efficiency. After completion, discharge the methyl bromide through the exhaust mechanism 6, and release the locking of the cover plate 2 by the locking mechanism 5. Finally, take out the fumigated fruit.
[0035] As Figures 1 - 3 shown, the locking mechanism 5 includes a display screen 51, a concentration detector 52, a locking sleeve 53, a first limiting member 54, an electric push rod 55 and a locking frame 56. The right side of the lower part of the cover plate 2 is connected with a display screen 51 through bolts. The display screen 51 is used to display the concentration of methyl bromide. The left side of the cover plate 2 is connected with a concentration detector 52. The upper and lower symmetrically distributed locking sleeves 53 are connected to the left part inside the fumigation box body 1. The left side of the front part of the cover plate 2 is connected with the upper and lower symmetric first limiting members 54 through bolts. A locking frame 56 is slidably connected between the first limiting members 54. The locking frame 56 is used to lock the cover plate 2. The locking frame 56 can be clamped with the adjacent locking sleeve 53. The left side of the front part of the cover plate 2 is connected with an electric push rod 55 through bolts. The telescopic end of the electric push rod 55 is connected with the locking frame 56.
[0036] It should be noted that during the process of fumigating the fruit with methyl bromide gas, in order to avoid the accidental opening of the cover plate 2 before the concentration of methyl bromide gas decreases, resulting in the discharge of methyl bromide gas and causing harm to the operator. After the cover plate 2 is turned to the left and closed, the electric push rod 55 is used to push the locking frame 56 to move, so that the locking frame 56 slides to the left and is clamped with the adjacent locking sleeve 53, thereby locking and fixing the cover plate 2 to prevent the cover plate 2 from accidentally opening. At the same time, the concentration detector 52 detects the methyl bromide gas inside the fumigation box body 1. The concentration value of the methyl bromide gas inside the fumigation box body 1 can be displayed on the display screen 51 in real time. After the value reaches the normal range, control the telescopic end of the electric push rod 55 to drive the locking frame 56 to slide back to its original position, so that the locking frame 56 is disengaged from the clamping with the adjacent locking sleeve 53, and the cover plate 2 is no longer locked and fixed. To sum up, by driving the locking frame 56 to slide through the telescopic end of the electric push rod 55, the locking frame 56 is clamped with the adjacent locking sleeve 53, thereby locking and fixing the cover plate 2 to prevent the cover plate 2 from accidentally opening. At the same time, the concentration of methyl bromide gas inside the fumigation box body 1 is detected in real time, which is convenient for the operator to judge the timing of opening the cover plate 2.
[0037] As Figure 1 、 Figure 4 and Figure 5As shown, the exhaust mechanism 6 includes an air pump 61, a connecting piece 62, a mounting piece 63, a ventilation pipe 64 and an air outlet assembly 65. The air pump 61 is connected to the right side of the lower inner portion of the fumigation box 1 by bolts, and the connecting piece 62 is connected to the right side of the lower inner portion of the fumigation box 1 by bolts. The connecting piece 62 is located on the upper side of the air pump 61, and the air pump 61 is connected and communicated with the connecting piece 62. The mounting piece 63 is connected to the right side of the upper inner portion of the fumigation box 1 by bolts, and a ventilation pipe 64 is connected between the mounting piece 63 and the upper front side of the connecting piece 62. An air outlet assembly 65 is connected between the connecting piece 62 and the fumigation box 1. The air outlet assembly 65 includes an air outlet pipe and a control valve. The air outlet pipe is connected between the upper rear side of the connecting piece 62 and the fumigation box 1, and a control valve is installed on the right inner portion of the air outlet pipe.
[0038] It should be noted that, when fumigating fruits, in order to improve the fumigation efficiency, the vacuum pump 61 can be started and the air outlet component 65 can be closed. At this time, the vacuum pump 61 will extract the methyl bromide located at the bottom of the fumigation box 1 and transport it upward through the vent pipe 64, so that the methyl bromide gas forms an internal circulation airflow in a vertical direction inside the fumigation box 1. Since the air outlet component 65 is in a closed state, the methyl bromide will not be discharged directly. After the fumigation of the fruit is completed, the air outlet component 65 is turned on, so that the methyl bromide gas is continuously discharged during the internal circulation process in the fumigation box 1, so that the methyl bromide gas concentration inside the fumigation box 1 begins to decrease. In summary, the methyl bromide gas in the fumigation box 1 is pumped by the vacuum pump 61 and discharged upward through the vent pipe 64, so that the internal circulation flow of the methyl bromide gas is realized, so that the fruit can be fully in contact with the methyl bromide gas during the fumigation process, thereby improving the fumigation efficiency.
[0039] like Figure 1 and Figure 6 As shown, it also includes a hair dryer mechanism 7, which includes a second limiting member 71, a sliding frame 72, a blocking frame 73 and a blowing assembly 74. The left side of the lower part of the cover plate 2 is connected to a front-to-back symmetrical second limiting member 71 by bolts, and a sliding frame 72 is slidably connected between the second limiting members 71. The front side of the sliding frame 72 is connected to the rear side of the locking frame 56, and the rear part of the sliding frame 72 is a left-protruding structure. The blocking frame 73 is connected to the top of the middle position of the sliding frame 72 by bolts. Two blowing assemblies 74 symmetrically installed in the middle position of the cover plate 2, the blowing assembly 74 includes a mounting frame 92 and a fan, and two mounting frames symmetrically installed in the middle position of the cover plate 2 are connected to the middle position of the cover plate 2. Fans are connected to the mounting frames 92, and the blowing assemblies 74 can be blocked by the blocking frame 73.
[0040] It should be noted that during the process of fruit fumigation, in order to further enable methyl bromide gas to fully contact the fruit surface, when the locking frame 56 slides under the action of the electric push rod 55 and is clamped with the locking sleeve 53, the locking frame 56 will drive the sliding frame 72 to slide, so that the blocking frame 73 slides and no longer blocks the blowing component 74. At this time, the blowing component 74 is started, so that the air flow velocity in the fumigation box body 1 is increased, so that the methyl bromide gas circulates more rapidly, and the fruit fumigation efficiency is further improved. To sum up, through the movement of the locking frame 56 to drive the movement of the sliding frame 72, the blocking frame 73 no longer blocks the blowing component 74, and then the air flow velocity in the fumigation box body 1 is increased, and the fruit fumigation efficiency is further improved.
[0041] As Figure 1 , Figure 7 and Figure 8 shown, it further includes an adjusting mechanism 8. The adjusting mechanism 8 includes a third limiting member 81, an adjusting frame 82, a roller 83, a magnetic attracting member 84 and a magnetic attracting frame 85. The left side of the connecting member 62 is connected with a third limiting member 81 through a bolt. The third limiting member 81 is slidably connected with an adjusting frame 82. The adjusting frame 82 is used to adjust the flow state of methyl bromide gas. A magnetic attracting member 84 is connected to the front side of the adjusting frame 82. A roller 83 is rotatably connected to the magnetic attracting member 84. The roller 83 can be pushed by the sliding frame 72. The magnetic attracting frame 85 is slidably connected to the lower rear part of the cover plate 2. The magnetic attracting frame 85 can be adsorbed and connected with the magnetic attracting member 84.
[0042] It should be noted that during the process of fruit fumigation, the cover plate 2 is in a closed state, and at the same time, the locking frame 56 is clamped with the corresponding locking sleeve 53. At this time, the methyl bromide gas is in a circulating flow state inside the fumigation box body 1. As the fruit fumigation ends, at this time, it is necessary to discharge the methyl bromide gas to reduce the concentration of methyl bromide gas inside the fumigation box body 1. By pushing the magnetic attracting frame 85, the magnetic attracting frame 85 is adsorbed and connected with the magnetic attracting member 84, and then the magnetic attracting frame 85 is pulled back to its original position, so that the magnetic attracting member 84 slides forward. At this time, the air pipe 64 is blocked by the adjusting frame 82, and the methyl bromide gas starts to be discharged through the air outlet component 65. When the concentration of methyl bromide gas is reduced to the normal standard, as the locking frame 56 slides and opens, it will drive the sliding frame 72 to slide, so that the left convex structure of the sliding frame 72 squeezes and pushes the roller 83, and then the roller 83 drives the magnetic attracting member 84 to slide backward to its original position. At this time, the magnetic attracting member 84 is separated from the magnetic attracting frame 85, and the adjusting frame 82 closes the air outlet component 65. To sum up, by pushing the magnetic attracting frame 85 to be adsorbed and connected with the magnetic attracting member 84, the pulling and controlling of the adjusting frame 82 to block the air pipe 64 is realized, the circulating state of the methyl bromide gas is ended, and the methyl bromide gas starts to be discharged, which is convenient for the operator to operate.
[0043] like Figure 1 , Figure 9 and Figure 10 As shown, a filter mechanism 9 is also included, and the filter mechanism 9 includes a fixing plate 91, a mounting frame 92 and a filter screen 93. The upper right side of the fumigation box body 1 is connected to the front and rear symmetrical fixing plates 91 by bolts, and the mounting frame 92 is slidably connected between the fixing plates 91. The mounting frame 92 is connected to the ventilation pipe 64, and the filter screen 93 is connected to the mounting frame 92.
[0044] It should be noted that when the methyl bromide gas circulates inside the fumigation box 1, the methyl bromide gas is filtered through the filter 93 to prevent the methyl bromide gas from carrying debris and affecting the fumigation of fruits. When there are a lot of debris on the filter 93, the installation frame 92 can be slid upward and removed, and then the filter 93 can be cleaned.
[0045] like Figure 2 and Figure 11 As shown, a reset mechanism 10 is also included, and the reset mechanism 10 includes a first fixed block 101, a spring 102 and a second fixed block 103. The first fixed block 101 is connected to the right side of the rear of the cover 2, and the second fixed block 103 is connected to the lower side of the magnetic bracket 85. A spring 102 is connected between the first fixed block 101 and the second fixed block 103.
[0046] It should be noted that when the magnetic bracket 85 is pushed, the second fixed block 103 will be driven to move synchronously, so that the spring 102 is compressed. When the magnetic bracket 85 and the magnetic element 84 are separated from each other, the magnetic bracket 85 will automatically reset under the action of the second fixed block 103 under the action of the spring 102.
[0047] It should be understood that the above description is only for exemplary purposes and is not meant to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will be included within the scope of the claims herein.
