On the contrary, the heater is closed and the cooler is started to cool the liquid. Both the heater and the cooler are prior arts and will not be elaborated here.

[0032] In a specific embodiment of the present utility model, the lifting platform 4 includes an electric telescopic rod 41, a support plate 42 and a controller 43. The support plate 42 is vertically slidably installed in the accommodation cavity 12. The guide post 7 penetrates through the support plate 42. The cross-section of the support plate 42 in the vertical direction is a right trapezoid, and the hypotenuse of the right trapezoid is located on the top surface of the support plate 42.

The controller 43 is fixed on the top of the outer side surface of the storage box 1 and is electrically connected to the plurality of electric telescopic rods 41 at the same time. A groove 421 with a triangular cross-section is provided on the top surface of the support plate 42. The structure of the support plate 42 is more conducive to the convergence and flow of the silage corn towards the outlet direction, and it can be taken out without manual participation.

[0033] In a specific embodiment of the present utility model, a discharge port 13 communicating with the accommodation cavity 12 is provided on the side wall of the storage box 1. A sealing plug 14 is detachably installed on the discharge port 13. A horizontally arranged pressing plate 15 is tightly pressed against the outer side of the sealing plug 14. Both ends of the pressing plate 15 are detachably connected to the storage box 1 through fastening bolts 16.

[0034] In this embodiment, the lower surface of the discharge port 13 is an inclined surface facilitating the discharge of materials. The top surface of the heat preservation cover 31 is collinear with the lower surface of the discharge port 13. Limit plates 8 are fixedly installed on both sides of the discharge port 13 on the top surface of the heat preservation cover 31. The inclination direction of the lower surface of the discharge port 13 is the same as that of the upper surface of the support plate 42.

[0035] In this embodiment, a humidity sensor 21 and a pressure sensor 22 electrically connected to the air extraction pump 2 are installed in the accommodation cavity 12. The humidity sensor 21 is used to detect the water vapor content in the accommodation cavity 12, and the pressure sensor 22 is used to detect the air pressure in the accommodation cavity 12, that is, the gas content. The storage box 1 is made of heat-conductive metal material, and the sealing plug 14 has a wedge-shaped structure, that is, the cross-section is trapezoidal. Here, as long as the relevant performance functions of the storage box 1 and the sealing plug 14 can be realized, they are within the protection scope of this application document.

[0036] Compared with the prior art, this temperature-controlled storage device for silage corn can simultaneously detect the temperatures inside and outside the silage corn at different heights through a plurality of temperature detectors 5 arranged in the vertical direction, judge the storage state of the silage corn according to the temperature situation, and can also judge the opening state of the temperature control component 3 according to the temperature situation. If the temperature is too high, the temperature control component 3 is started to cool the inside of the storage box 1. If the temperature is too low, the temperature control component 3 is started to heat the inside of the storage box 1, effectively ensuring that the inside of the storage box 1 is within the most suitable temperature threshold range for storing corn. Through the setting of the air extraction pump 2, the inside of the storage box 1 can be kept in a vacuum state, and moisture can also be removed to a certain extent, providing a better environment for the storage of silage corn.

[0037] The working process of the temperature-controlled storage device for silage corn of the present utility model is as follows: After removing the cover 6, the processed silage corn is filled into the accommodation cavity 12 from the feed inlet 11. At this time, the electric telescopic rod 41 is in a compressed state, and the support plate 42 is located at a position close to the bottom of the accommodation cavity 12. After the silage corn is loaded, the cover 6 is covered, and the control box 36 of the temperature control component 3 is started. The control box 36 controls the air extraction pump 2 to start to perform vacuum treatment on the accommodation cavity 12. After the humidity sensor 21 and the pressure sensor 22 detect that the environmental state in the accommodation cavity 12 meets the storage requirements, they transmit electrical signals to turn off the air extraction pump 2, and the loading and storage of the silage corn are completed.

[0038] During the storage process, the temperature detector 5 continuously detects the temperatures at different positions inside the accommodation chamber 12 and transmits the temperature data to the control box 36 for analysis and processing. If the temperature is too high or too low, the suction pump 33 and the regulator 35 are turned on, and the control valves at the inlet and outlet of the liquid storage tank 34 are opened. The outlet at the bottom of the liquid storage tank 34 is connected to the inlet of the regulator 35. Under the action of its own weight, the liquid automatically flows into the regulator 35. The regulator 35 is arranged lower than the liquid storage tank 34. After the regulator 35 cools or heats the liquid, the liquid flows into the transmission pipe 32. The transmission pipe 32 is located below the regulator 35. The liquid in the transmission pipe 32 transmits the cold air or heat to the storage tank 1 within the maximum range through the coiled transmission pipe 32 to change the temperature inside the storage tank 1. After the liquid in the transmission pipe 32 flows to the bottommost part, under the action of the suction pump 33, it enters the liquid storage tank 34 from the outlet of the transmission pipe 32 through the suction pump 33 and from the inlet at the top of the liquid storage tank 34.

[0039] When it is necessary to take out the silage corn for use, a material taking box is placed on the ground below the proximity of the limit plate 8. The pressing plate 15 is disassembled and the sealing plug 14 is pulled out. The rising button on the controller 43 located above the discharge port 13 is pressed. The controller 43 starts the electric telescopic rod 41 to extend and pushes the supporting plate 42 to move upward. The upward movement of the supporting plate 42 drives the silage corn inside the accommodation chamber 12 to move upward. When the silage corn moves to the discharge port 13, it will leak out from the discharge port 13. After the supporting plate 42 is controlled to rise to a certain height, the rising button is released, and the supporting plate 42 remains stationary. The silage corn continuously leaks out from the discharge port 13. Until an appropriate amount is taken, the descending button on the controller 43 is pressed. The controller 43 starts the electric telescopic rod 41 to compress and pulls the supporting plate 42 downward. The silage corn on the supporting plate 42 moves downward accordingly away from the discharge port 13, and the discharge port 13 no longer leaks silage corn. After the supporting plate 42 moves in place, the pressing of the descending button is stopped. The sealing plug 14 is inserted into the discharge port 13, and the pressing plate 15 is pressed on the sealing plug 14 to tightly fix the sealing plug 14. At this time, the air extraction pump 2 continues to perform air extraction treatment on the accommodation chamber 12 to ensure the storage environment inside the accommodation chamber 12.

For the same or similar parts among the embodiments, reference can be made to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple.
