Description

Technical Field

[0001] The present invention belongs to the technical field of seed storage, and specifically relates to a low-temperature micro-freezing fresh-keeping storage device for wheat seeds. Background Art

[0002] Low-temperature micro-freezing fresh-keeping storage means that within a temperature range lower than normal temperature, by placing seeds under micro-freezing conditions (usually around -3°C to -5°C), their metabolic activities are slowed down, germination and senescence are prevented, and at the same time, the viability and quality of the seeds are maintained. For the storage of wheat seeds, the growth of seeds is delayed and their vitality is maintained through micro-freezing technology, so as to ensure that the seeds are not damaged during storage.

[0003] In the existing low-temperature micro-freezing fresh-keeping storage devices for wheat seeds, during use, in order to ensure good low-temperature micro-freezing fresh-keeping quality of wheat seeds, during micro-freezing treatment, it is usually necessary to pre-dry the wheat seeds first to reduce the water content inside the wheat seeds and avoid the formation of ice crystals inside the seeds during micro-freezing, which may damage the wheat seeds. Currently, a split-type drying treatment mechanism and a split-type micro-freezing treatment mechanism are used in cooperation. A certain amount of wheat seeds are placed in a drying device for drying, taken out and transferred to a micro-freezing mechanism for micro-freezing, and then transferred to a storage tank for low-temperature micro-freezing storage after micro-freezing. During this period, there are multiple transfer and loading / unloading processes, with many intermediate processes, and the micro-freezing storage efficiency is low. It is impossible to achieve rapid and continuous processing from pre-drying to micro-freezing and then to fresh-keeping storage, and the use effect is not good. Summary of the Invention

The number of the discharge ports 73 is the same as that of the adapter ports 13. The adapter ports 13 correspond to the adjustable support assemblies 6 one by one. The adapter ports 13 are located on the moving path of the discharge port 73. A damping sleeve (not shown in the figure) is provided between the cylinder body 71 and the heat insulation sleeve 5 to ensure relative stability after the rotation of the rotating cylinder body 71, avoid secondary offset, and achieve dynamic sealing at the same time.

Through the cooperation of the sleeve shaft 92 and the socket cavity 15, while ensuring the up-and-down movement of the composite treatment cylinder 7 is controlled, the composite treatment cylinder 7 is allowed to deflect itself.

[0035] Among them, a feeding assembly 12 is fixedly provided at the top of the storage tank 1. The outlet end of the feeding assembly 12 faces the adjustable support assembly 6. The feeding assembly 12 includes a feeding frame 121, a feeding pipe 122 and a sealing plug 123. The feeding pipe 122 is fixedly sleeved at the top of the storage tank 1, and the lower end is located above the adjustable support assembly 6. The upper end of the feeding pipe 122 is fixedly connected and communicated with the feeding frame 121. The sealing plug 123 is movably sleeved at the upper end of the feeding pipe 122. An electric push rod 122 is provided inside the feeding frame 121, and the movable end of the electric push rod 122 is fixedly connected with the sealing plug 123.

[0036] The feeding component 12 realizes the feeding process of wheat seeds. When the feeding tube 122 is opened, the wheat seeds are directional-loaded into the adjustable support component 6, and the sealing plug 123 is sleeved in the feeding tube 122 to prevent the wheat seeds from continuing to fall. The outside of the processing box 2 can be connected to an external ventilation structure. When drying the wheat seeds, the air volume is introduced into the processing box 2. The small gap between the sealing plug 123 and the feeding tube 122 can realize the outlet of the air volume fed into the processing box 2.

[0037] First embodiment: When in use, the wheat seeds to be processed are put into the feeding frame 121 of the feeding component 12, the electric push rod 2 is started and drives the sealing plug 123 to move up to open the feeding tube 122, and the wheat seeds fall into various adjustable support components 6 through the feeding tube 122, and fall on the top of the carrier plate 63, the heating tube 4 is started, the temperature in the processing box 2 rises, and the heat acts on the wheat scattered on the carrier plate 63, so that the internal moisture of the wheat evaporates, and the lifting control component 9 is started. The electric push rod 1 93 drives the cross plate 91 and the sleeve shaft 92 to move downward, so that the installed composite processing cylinder 7 moves downward, the cylinder body 71 moves downward along the inside of the heat insulation sleeve 5, and drives the mounting ring 8 to move downward along the adapter 13, thereby driving the carrier plate 63 to rotate and swing downward through the sleeve rod 64, and drives the elastic rod 65 to stretch and deform, and as the cylinder body 71 moves downward a short distance and then moves upward to reset, the carrier plate 63 swings up and resets, reciprocating. The top of the carrier plate 63 is vibrated and acts on the wheat seeds at the top. The wheat seeds vibrate on the carrier plate 63 and cooperate with the heating tube 4 to complete the drying of the wheat seeds and reduce the moisture content. After drying for a certain period of time, the cylinder 71 is manually pushed to make the cylinder 71 deflect laterally around the inside of the heat insulation sleeve 5, so that the guide port 73 rotates to the top of the adapter port 13, and then the lifting control component 9 is started again to drive the cylinder 71 to move down again, so that the guide port 73 moves downward to the adapter port 13, and at this time the carrier plate 63 keeps tilting downward, the dried wheat seeds on the top of the carrier plate 63 rotate and roll down, and fall into the inside of the cylinder 71, and then fall into the storage tank 1 through the dispersion micro-freezing component 10, completing the storage after drying and micro-freezing; then the composite processing cylinder 7 is raised and the composite processing cylinder 7 is rotated horizontally to reset, and the loading component 12 is reopened to put the next group of wheat seeds to be micro-frozen and stored into the processing box 2 for the next group of processing.

[0038] First, through the cooperation of the adjustable support assembly 6, the composite treatment cylinder 7, and the dispersion and micro-freezing assembly 10, continuous processing of drying and micro-freezing storage is achieved. The up and down movement of the composite treatment cylinder 7 completes vibration dispersion, realizes uniform drying of wheat seeds in the treatment box 2, improves the drying effect, reduces the moisture content, avoids internal frostbite during micro-freezing, and automatically controls the carrier plate 63 in the adjustable support assembly 6 to tilt and automatically discharge materials after deflecting and moving downward, quickly realizing efficient discharging after dispersion drying, reducing intermediate feeding, discharging, and transfer processes, improving the continuous processing efficiency, and achieving continuous drying and micro-freezing storage processing for batch wheat seeds, with automatic integrated processing and high comprehensive processing efficiency.

[0039] Among them, a cold air input pipe is provided on the side of the storage tank 1, and the cold air input pipe is communicated with the cold air distribution assembly 3. The cold air distribution assembly 3 includes a communication cavity 31, a sleeve 32, and a gas guide pipe 33.

The gas guide pipe 33 is fixedly connected to the bottom of the inner cavity of the storage tank 1 and is communicated with the communication cavity 31.

[0040] Through the cold air input pipe, the cold air input of the external refrigeration and ventilation structure can be realized, the cold air is input into the cold air distribution assembly 3, and the cold air introduction of the storage tank 1 and the dispersion and micro-freezing assembly 10 is completed, realizing micro-freezing storage processing.

[0041] Among them, a dispersion and micro-freezing assembly 10 is fixedly provided inside the composite treatment cylinder 7. The dispersion and micro-freezing assembly 10 includes an intermediate rod 101, a bottom cavity 102, a spiral blade 103, and air holes 104. The intermediate rod 101 is fixedly connected inside the cylinder body 71. The spiral blade 103 is fixedly sleeved on the outer side surface of the intermediate rod 101 and is fixedly sleeved on the inner wall of the cylinder body 71. The bottom cavity 102 is opened at the bottom of the intermediate rod 101. The air holes 104 are opened on the outer side surface of the intermediate rod 101. The bottom of the intermediate rod 101 is movably sleeved in the sleeve 32.

[0042] By utilizing the spiral channel formed by the dispersion and micro-freezing assembly 10 and the cylinder body 71, during the process of guiding the dried wheat seeds to spiral down, cooperating with the cold air input into the spiral channel, full micro-freezing treatment is realized, ensuring the uniformity of micro-freezing.

[0043] Among them, a bypass mechanism is provided inside the composite treatment cylinder 7. The air inlet end of the bypass mechanism is communicated with the inside of the composite treatment cylinder 7. The bypass mechanism includes a cold air output pipe.

[0044] Through the bypass mechanism, the cold air input into the equipment is output, and in cooperation with the cold air output pipe and the external refrigeration and ventilation mechanism, the cold air circulation treatment is completed.

[0045] Among them, the bypass mechanism also includes a connecting port 14, a bypass port 16 and a connecting cover 11. The connecting port 14 is opened inside the cylinder 71. The two ends of the connecting port 14 are respectively connected to the bottom chamber of the cylinder 71 and the sleeve chamber 15. One end of the bypass port 16 is connected to the sleeve chamber 15. The connecting cover 11 is fixedly connected to the top of the storage tank 1 and is sleeved on the outside of the cylinder 71. The internal annular cavity of the connecting cover 11 is connected to the other end of the bypass port 16, and the outer side surface of the connecting cover 11 is connected to the cold air output pipe.

[0046] The bypass mechanism guides the cold air in the dispersed micro-freezing assembly 10 to the outside along the cylinder 71, and circulates it into the refrigeration and ventilation mechanism to complete the circulating cold air treatment. The connecting cover 11 ensures that normal cold air can be guided out when the cylinder 71 rotates.

[0047] Second embodiment: When pre-drying the wheat seeds before micro-freezing, the external refrigeration equipment is started, and the cold air is input into the cold air distribution component 3 through the cold air input pipe, and the cold air is input into the connecting cavity 31, and distributed to the sleeve 32 and the air guide pipe 33. The cold air entering the air guide pipe 33 is further input into the storage tank 1 through the side hole, and the internal temperature of the storage tank 1 is reduced. The cold air in the sleeve 32 is introduced upward into the bottom cavity 102 of the middle rod 101 in the dispersion micro-freezing component 10, and is input into the spiral blade 103 along the air hole 104. The wheat seeds that fall into the cylinder 71 slide downward along the spiral blade 103 and contact with the cold air flowing out from various places during the falling process. The micro-freezing process is completed during the spiral sliding period, and the cold air is guided upward through the connecting port 14, the bypass port 16 and the connecting cover 11 of the bypass mechanism, and flows back to the external refrigeration air outlet mechanism through the external cold air output pipe.

[0048] First, through the cylinder 71 and the dispersion micro-freezing component 10, after the drying is completed, the cold air input into the dispersion micro-freezing component 10 and the wheat seeds sliding downward along the spiral blade 103 are matched with the above-mentioned drying treatment structure, and the wheat seeds are fully dried and introduced into the spiral channel surrounded by the spiral blade 103 and the cylinder 71 in small quantities and multiple times, and the cold air introduced into the channel is matched, so that the surface of the wheat seeds is fully in contact with the cold air, thereby improving the effect of the micro-freezing treatment of the wheat seeds after drying, and completing efficient and uniform micro-freezing treatment by extending the micro-freezing time and increasing the micro-freezing path.

[0049] Among them, the bypass mechanism is the guide port 17, which is opened on the outer surface of the cylinder 71 and is located below the annular groove 72. The guide port 17 corresponds one-to-one with the adapter port 13, and the adapter port 13 is located on the rotation path of the guide port 17. The outer side surface of the storage tank 1 is fixedly connected to the cold air output pipe.

[0050] The bypass mechanism introduces cold air into the processing box 2, uses the processing box 2 to export the cold air to the external refrigeration and ventilation mechanism and enters the cycle, and by introducing the cold air into the processing box 2, the micro-freezing and cooling treatment of wheat seeds in the processing box 2 is realized.

[0051] Third Embodiment: When processing seeds that have been sufficiently dried, the dried seeds are put into the adjustable support assembly 6 through the feeding assembly 12. At the same time, the external refrigeration air outlet mechanism is maintained to input cold air into the cold air distribution assembly 3, and part of the cold air is input into the cylinder body 71 through the dispersion and micro-freezing assembly 10, and is input along the diversion port 17 and the adapter port 13 to the inclined cavity 62 of the adjustable support assembly 6, and acts on the wheat seeds upward through the small holes on the carrier plate 63. At the same time, the processing box 2 is filled, and the continuously filled cold air is circulated and input into the external refrigeration air outlet mechanism through the output pipe arranged outside the processing box 2. At the same time, the up and down movement of the composite processing cylinder 7 is maintained, and the wheat seeds on the carrier plate 63 are vibrated and dispersed by the downward swing and reset of the carrier plate 63, so as to realize the full micro-freezing and cooling of the wheat seeds. After uniform micro-freezing treatment, the composite processing cylinder 7 is pushed to deflect horizontally, and the composite processing cylinder 7 is controlled to move downward. The carrier plate 63 tilts downward to guide the micro-frozen wheat seeds into the cylinder body 71, and the secondary micro-freezing is completed along the dispersion and micro-freezing assembly 10, and the storage after full micro-freezing treatment is completed.

[0052] First, by placing the wheat seeds into the adjustable support assembly 6 of the processing box 2, cooperating with the opening of the diversion port 17 and the movement control of the composite processing cylinder 7, the dispersion and vibration of the wheat seeds in the adjustable support assembly 6 are realized after feeding, and the micro-freezing treatment is carried out in cooperation with the cold air flowing into the processing box 2. And when the composite processing cylinder 7 acts and automatically realizes the export of the wheat seeds in the adjustable support assembly 6, and in cooperation with the dispersion and micro-freezing assembly 10 in the composite processing cylinder 7, the double micro-freezing treatment is realized. For wheat seeds with lower water content, the cold air micro-freezing treatment under two dispersions of the wheat seeds can be completed, ensuring that the wheat seeds have a sufficient low-temperature micro-freezing fresh-keeping storage effect.

[0053] The working principle and use process of the present invention are as follows: when in use, the wheat seeds to be processed are put into the feeding frame 121 of the feeding component 12, the electric push rod 2 is started and drives the sealing plug 123 to move upward to open the feeding tube 122, and the wheat seeds fall into various adjustable support components 6 through the feeding tube 122 and fall on the top of the carrier plate 63, the heating tube 4 is started, the temperature in the processing box 2 rises, and the heat acts on the wheat scattered on the carrier plate 63, so that the moisture inside the wheat evaporates, the lifting control component 9 is started, and the electric push rod 1 93 drives the horizontal plate 9 1 and the sleeve shaft 92 move downward, so that the installed composite treatment cylinder 7 moves downward, the cylinder body 71 moves downward along the inside of the heat insulation sleeve 5, and drives the installation ring 8 to move downward along the adapter 13, thereby driving the carrier plate 63 to rotate and swing downward through the sleeve rod 64, and driving the elastic rod 65 to stretch and deform. As the cylinder body 71 moves downward a short distance and then moves upward and resets, the carrier plate 63 swings upward and resets. The reciprocating action causes the top of the carrier plate 63 to vibrate and act on the wheat seeds at the top. The wheat seeds vibrate on the carrier plate 63 and cooperate with The heating tube 4 completes the drying of the wheat seeds and reduces the moisture content. After drying for a certain period of time, the cylinder 71 is manually pushed to make the cylinder 71 deflect laterally around the inside of the heat insulation sleeve 5, so that the guide port 73 rotates to the top of the adapter port 13, and then the lifting control component 9 is started again to drive the cylinder 71 to move down again, so that the guide port 73 moves downward to the adapter port 13, and at this time the carrier plate 63 keeps tilting downward, and the dried wheat seeds on the top of the carrier plate 63 rotate and roll down, and fall into the inside of the cylinder 71, and then fall into the dispersion micro-freezing component 10 downward. To the storage tank 1, complete the storage after drying and slight freezing; then, the composite processing cylinder 7 is raised and rotated horizontally to reset, and the loading assembly 12 is reopened to put the next group of wheat seeds to be slightly frozen and stored into the processing box 2 for the next group of processing; and the wheat seeds that fall into the cylinder 71 slide downward along the spiral blade 103, and come into contact with the cold air flowing out from various places during the falling process, and the slight freezing treatment is completed during the spiral sliding period, and the cold air is discharged through the bypass mechanism, and flows back to the external refrigeration air outlet mechanism through the external cold air output pipe.
