A fixed component and a detection component are arranged on the upper surface of the workbench.

[0054] In use, the support main frame 1 is pushed to the liquor jar after distillation, so that the alcohol meter 44 is moved above the liquor jar, then the staff manually rotates the winder 45 to loosen the pull rope, and then starts the first multi-stage cylinder 41, the telescopic rod of the first multi-stage cylinder 41 is elongated to drive the transparent limiting cover 42, the magnet 43 and the alcohol meter 44 to move downwards, so that the alcohol meter 44 is moved close to the liquor, then the first multi-stage cylinder 41 is stopped, and the winder 45 is controlled to wind the pull rope, so as to drive the magnet 43 to move outward, so that the magnet 43 loosens the alcohol meter 44, so that the alcohol meter 44 enters the liquor jar and suspends in the liquor, in this way, the degree of the liquor after distillation in the liquor jar can be detected, during which the second multi-stage cylinder 51 is started, the telescopic rod of the second multi-stage cylinder 51 is elongated to drive the transparent fixed cover 52 and the mercury thermometer 53 to move downwards, so that the lower end of the mercury thermometer 53 extends into the liquor in the liquor jar to detect the temperature of the liquor, then the values on the alcohol meter 44 and the mercury thermometer 53 are recorded, and the two values can be used to obtain the accurate degree of the liquor, after the detection is completed, the telescopic rod of the first multi-stage cylinder 41 is elongated again to drive the transparent limiting cover 42 and the magnet 43 to move downwards to cover the alcohol meter 44, then the pull rope is loosened by the winder 45, so that the magnet 43 is attracted to clamp the alcohol meter 44, then the telescopic rod of the first multi-stage cylinder 41 is retracted to drive the transparent limiting cover 42, the magnet 43 and the alcohol meter 44 to move upwards out of the liquor jar, and the telescopic rod of the second multi-stage cylinder 51 is retracted to drive the transparent fixed cover 52 and the mercury thermometer 53 to move upwards to reset, in this way, the degree of the liquor can be accurately detected, and the staff can also push the support main frame 1 to the raw material pile being fermented, start the second multi-stage cylinder 51, the telescopic rod of the second multi-stage cylinder 51 is elongated to drive the transparent fixed cover 52 and the mercury thermometer 53 to move downwards, so that the mercury thermometer 53 moves downwards to insert into the raw material pile to detect the temperature of the raw material being fermented, which is convenient for the staff to monitor the temperature of the raw material during fermentation, so as to avoid that the high temperature during fermentation affects the quality and taste of the liquor, after the detection is completed, the transparent fixed cover 52 and the mercury thermometer 53 are moved upwards to reset by the second multi-stage cylinder 51, and then the support main frame 1 is pushed away.
[0055] Example 2
[0056] On the basis of example 1, as Figure 2 , Figure 5 and Figure 6Also shown, there is a clear mechanism 6 for marking the degree of liquor on the alcohol meter 44, the clear mechanism 6 comprises a floating block 61, an expansion block 62, a gas cylinder 63 and a piston 64, the expansion block 62 is fixed to the inner wall of the front side of the transparent limiting cover 42, the floating block 61 is slidably connected inside the transparent limiting cover 42, the floating block 61 is used for marking the degree of liquor on the alcohol meter 44, the floating block 61 is in contact with the expansion block 62, the top of the front side magnet 43 is fixedly connected with the gas cylinder 63, the piston 64 is slidably connected inside the gas cylinder 63, the rear part of the piston 64 is in contact with the alcohol meter 44, and the piston 64 is connected with the spring inside the gas cylinder 63. Initially, the piston 64 is in contact with the alcohol meter 44, and the spring inside the gas cylinder 63 is in a compressed state, when the magnet 43 drives the gas cylinder 63 and the piston 64 to move outward, the spring inside the gas cylinder 63 resets, driving the piston 64 to move backward to reset, thereby sucking the gas in the expansion block 62 into the gas cylinder 63, so that the expansion block 62 no longer abuts against the floating block 61, and the alcohol meter 44 falls into the wine cylinder to detect the degree of liquor. After detection is completed, the winding device 45 is rotated to wind the pull rope, so that the magnet 43 is separated, and then the transparent limiting cover 42 is controlled to move downward, driving the magnet 43, the gas cylinder 63, the piston 64 and the floating block 61 to move downward into the liquor. Since the depth of the alcohol meter 44 is the degree of liquor, the liquid level of the liquor rises, and the alcohol meter 44 and the floating block 61 also float with the liquid level of the liquor. The rising of the liquid level of the liquor will not affect the accuracy of the measurement of the degree of liquor. Then the magnet 43 moves downward to the lower part of the alcohol meter 44, and the winding device 45 is controlled to relax the pull rope, so that the magnet 43 is attracted to clamp the alcohol meter 44, and the magnet 43 moves inward to drive the gas cylinder 63 and the piston 64 to move inward, so that the piston 64 is in contact with the alcohol meter 44 and is extruded to move forward, thereby extruding the air in the gas cylinder 63 into the expansion block 62, so that the expansion block 62 expands and extrudes the floating block 61 to move backward to abut against the alcohol meter 44. In this way, the degree of liquor on the alcohol meter 44 can be marked, which is convenient for subsequent reading by the staff and avoids affecting the accuracy of the value when the alcohol meter 44 is taken out and read again.
[0057] As Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, the protection mechanism 7 is used for protecting the mercury thermometer 53, and the protection mechanism 7 comprises a baffle 71, a plastic baffle 72 and elastic ropes 73. The baffle 71 is slidably connected to the lower portion of the transparent fixed cover 52 and is used for protecting the mercury thermometer 53. The plastic baffle 72 is connected to the middle portion of the baffle 71. Two elastic ropes 73 are connected to the left front bottom of the support plate 2 and are connected to the top of the baffle 71 through the upper portion of the transparent fixed cover 52. When the transparent fixed cover 52 moves downward, the baffle 71 and the plastic baffle 72 are driven to move downward. When the elastic ropes 73 are straightened, the transparent fixed cover 52 continues to move downward, the elastic ropes 73 limit the baffle 71, the detection part of the mercury thermometer 53 passes through the plastic baffle 72, the mercury thermometer 53 can detect the temperature of the white wine and the fermentation raw materials, and the glass tube part of the mercury thermometer 53 can be protected to avoid damage. When the transparent fixed cover 52 moves upward to reset, the elastic ropes 73 relax, the baffle 71 moves downward to block the mercury thermometer 53, and the plastic baffle 72 can scrape off the raw materials adhered to the mercury thermometer 53. Thus, the mercury thermometer 53 can be protected to avoid damage caused by external factors when not in use.
[0058] As shown in Figure 1 , Figure 2 , Figure 9 and Figure 10 , the cleaning mechanism 8 is used for cleaning the baffle 71 and the mercury thermometer 53, and the cleaning mechanism 8 comprises a water tank 81, a water pump 82 and a spray pipe 83. The water tank 81 is fixedly connected to the bottom of the support plate 2. The water pump 82 is connected to the lower portion of the water tank 81 through bolts. The bottom of the water pump 82 is connected to the spray pipe 83. The spray pipe 83 is used for flushing the baffle 71 and the mercury thermometer 53, and the spray pipe 83 passes through the lower portion of the water tank 81. The staff fills the water tank 81 with water. After the mercury thermometer 53 completes the temperature detection of the fermentation raw materials, the staff pushes the support frame 1 away from the fermentation raw material pile, then starts the water pump 82, the water pump 82 sends water into the spray pipe 83, the spray pipe 83 flushes the bottom of the baffle 71, at the same time, the staff manually presses the baffle 71 upward, the detection part of the mercury thermometer 53 passes through the plastic baffle 71, the spray pipe 83 flushes the mercury thermometer 53, avoids the adhesion of the liquid during fermentation on the mercury thermometer 53, and can also flush the alcohol meter 44. Thus, the mercury thermometer 53 and the alcohol meter 44 can be kept clean, and the long-term non-cleaning will not affect the detection accuracy of the mercury thermometer 53. After flushing, the water pump 82 is closed, and the baffle 71 is loosened and reset.
[0059] As shown in Figure 1 , Figure 2 and Figure 11As shown, the extension mechanism 9 is used to drive the support plate 2 to move, the extension mechanism 9 comprises a push rod 91 and a linear spring 92, the push rod 91 is slidably connected to the upper portion of the support frame 1, the push rod 91 is used to drive the support plate 2 to move, the left side of the push rod 91 is fixedly connected with the right side of the support plate 2, the right portion of the push rod 91 is connected with two clamping blocks, the upper portion of the support frame 1 is provided with two clamping grooves, the push rod 91 is sleeved with the linear spring 92, and the two ends of the linear spring 92 are respectively connected with the right side of the push rod 91 and the right upper side of the support frame 1. When the temperature of the raw material pile being fermented needs to be detected, the push rod 91 is manually pushed to move to the left, the linear spring 92 is compressed, the clamping blocks on the push rod 91 are clamped into the clamping grooves on the support frame 1, so that the support plate 2 can be driven to move to the left, the support plate 2 can be moved to the highest position above the raw material pile, so that the mercury thermometer 53 can detect the temperature of the upper part of the raw material pile, so that the mercury thermometer 53 can detect the temperature of the core of the raw material pile, thereby improving the accuracy of temperature detection, after detection, the clamping blocks on the push rod 91 are manually squeezed inward, the clamping blocks on the push rod 91 are separated from the clamping grooves on the support frame 1, the linear spring 92 is reset, the push rod 91 is driven to move to the right and reset, thereby driving the support plate 2 to move to the right and reset.
