[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] 1. The solution sampling device for the production of polyurethane long-acting slow-release urea, through the set discharging component, mixes the urea solution evenly, then starts the second motor to rotate the third rotating shaft, the rotation of the third rotating shaft will rotate the fourth gear, and at the same time drive the second half gear to rotate, because the fourth gear is meshed with the third gear, the rotation of the fourth gear will rotate the third gear, and at the same time drive the first half gear to rotate, so the operation of the second motor will cause the second half gear and the first half gear to rotate in opposite directions, because the second half gear and the second half gear are meshed with the fifth gear, so the second motor is started, the second half gear is first meshed with the third gear, and the third half gear is meshed with the fifth gear. The five gears are meshed. At this time, the first half gear and the fifth gear are in a non-meshed state, so the second half gear will drive the fifth gear to rotate, thereby opening the valve, and the urea solution in the second box will be discharged from the metal water pipe. The second motor continues to work to make the first half gear mesh with the fifth gear. At this time, the second half gear is not meshed with the fifth gear, so the rotation of the first half gear will cause the fifth gear to rotate in the opposite direction, thereby closing the valve and preventing the urea solution from being discharged from the second box. The operation of the second motor can control the discharge amount of the urea solution in the second box, so that the amount of solution discharged each time is equal, which is convenient for subsequent experimental comparison.

[0021] 2. The solution sampling equipment for the production of polyurethane long-acting slow-release urea, through the set conveying component, before starting the second motor, the sampling bottle is placed in the placement plate, and then the second motor is started. The second motor works to rotate the third pulley, and the third pulley rotates the fourth pulley through the cooperation of the second belt, thereby driving the fourth rotating shaft to rotate, and the fourth rotating shaft drives the first bevel gear to rotate. Since the first bevel gear is meshed with the second bevel gear, the first bevel gear drives the second bevel gear to rotate, thereby rotating the fifth rotating shaft, and the fifth rotating shaft drives and the first sprocket The first sprocket rotates with the third sprocket, and the first sprocket rotates with the cooperation of the first chain, thereby driving the first roller to rotate, and the third sprocket rotates with the cooperation of the second chain, thereby driving the second roller to rotate. The same-direction rotation of the first roller and the second roller will move the conveyor belt forward, thereby driving the sampling bottle forward. When the moving bottle moves to the bottom of the metal water pipe, the valve will open, and the urea solution in the first box will be discharged into the sampling bottle. When the sampling bottle is about to leave the bottom of the metal water pipe, the valve will close. The device can fill multiple sampling bottles with urea solution, which can make the urea solution experiment more accurate.

[0022] 3. The solution sampling equipment for the production of polyurethane long-acting slow-release urea pours the urea solution into the first box through the feeding barrel by means of the stirring mechanism. After the pouring is completed, the first motor is started to rotate the first pulley. The first pulley rotates the second pulley through the cooperation of the first belt, thereby rotating the first rotating shaft, thereby rotating the rotating frame, and the rotating frame drives the three stirring shafts to revolve. Since the first gear is meshed with the second gear and the second gear is fixed, the three stirring shafts will rotate at the same time as they revolve. The urea solution in the first box can be mixed more evenly through the revolution and rotation of the three stirring shafts.

[0023] 4. The solution sampling equipment for the production of polyurethane long-acting slow-release urea starts the temperature control device through the temperature control mechanism set up to make the temperature control tube in the second box work, so that the temperature in the second box is maintained at about 20 degrees. The fan is started to suck the outside air into the second box to keep the air at about 20 degrees. After that, the continuous operation of the fan will make the gas in the second box flow to the left through the exhaust hood, so that the air temperature around the sampling bottle can be maintained at a constant temperature when the urea solution is filled, so as to ensure the accuracy of the test results.

[0046] Embodiment 2

[0047] See also Figure 1-3 , and on the basis of the first embodiment, a stirring mechanism 7 is further obtained.

[0048] Furthermore, the stirring mechanism 7 includes a first rotating shaft 71, which is arranged on the top of the first box body 2, and a fixed cylinder 72 is fixedly connected to the top of the inner wall of the first box body 2, and a rotating frame 73 is fixedly connected to the bottom end of the first rotating shaft 71, and a stirring shaft 74 is arranged at the bottom of the rotating frame 73.

[0050] Furthermore, a hole matching the stirring shaft 74 is formed at the bottom of the rotating frame 73 , and the surface of the stirring shaft 74 passes through and is rotatably connected in the hole, and the first gear 75 is meshed with the second gear 76 .

[0051] Embodiment 3

[0052] See also Figure 8 , and on the basis of the first embodiment, a temperature control mechanism 9 is further obtained.

[0053] Furthermore, the temperature control mechanism 9 includes a second box body 91, which is symmetrically fixedly connected to the bottom of the base 1 near the right side in a front-to-back manner, a fan 92 is symmetrically fixedly connected to the inner wall of the second box body 91 near the right side in an upper and lower manner, a temperature control tube 93 is fixedly connected to the top of the inner wall of the second box body 91, a temperature control device 94 is fixedly connected to the top of the second box body 91, an air outlet groove 96 is opened on the left side of the inner wall of the second box body 91, and an exhaust hood 95 is fixedly connected to the left side of the second box body 91.

[0054] In actual operation, when the device is used, the urea solution is poured into the first box body 2 through the feeding barrel 3 by the stirring mechanism 7. After the pouring is completed, the first motor 78 is started to rotate the first pulley 79. The first pulley 79 rotates the second pulley 711 through the cooperation of the first belt 712, so that the first rotating shaft 71 rotates, so that the rotating frame 73 rotates, and the rotating frame 73 drives the three stirring shafts 74 to revolve. Since the first gear 75 is meshed with the second gear 76, and the second gear 76 is fixed, the three stirring shafts 74 will also rotate while revolving. The urea solution in the first box body 2 can be mixed more evenly through the revolution and rotation of the three stirring shafts 74.

[0055] After the urea solution is evenly mixed, the second motor 8111 is started to rotate the third shaft 815. The rotation of the third shaft 815 causes the fourth gear 816 to rotate, and at the same time drives the second half gear 817 to rotate. Since the fourth gear 816 is meshed with the third gear 813, the rotation of the fourth gear 816 causes the third gear 813 to rotate, and at the same time drives the first half gear 814 to rotate. Therefore, the operation of the second motor 8111 causes the second half gear 817 and the first half gear 814 to rotate in opposite directions. Since the second half gear 817 and the second half gear 817 are meshed with the fifth gear 818, the second motor 8111 is started, and the second half gear 817 is first meshed with the fifth gear 818. At this time, the first half gear 814 is rotated in opposite directions. The half gear 814 and the fifth gear 818 are in a non-engaged state, so the second half gear 817 drives the fifth gear 818 to rotate, thereby opening the valve 5, and the urea solution in the second box 91 is discharged from the metal water pipe 6. The second motor 8111 continues to work to make the first half gear 814 mesh with the fifth gear 818. At this time, the second half gear 817 is not meshed with the fifth gear 818, so the rotation of the first half gear 814 causes the fifth gear 818 to rotate in the opposite direction, thereby closing the valve 5, so that the urea solution will not be discharged from the second box 91. The discharge amount of the urea solution in the second box 91 can be controlled by the operation of the second motor 8111, so that the amount of solution discharged each time is equal, which is convenient for subsequent experimental comparison;

[0056] Before starting the second motor 8111, place the sampling bottle in the placement tray 8221, and then start the second motor 8111. The operation of the second motor 8111 will cause the third pulley 821 to rotate, and the third pulley 821 rotates the fourth pulley 824 through the cooperation of the second belt 825, thereby driving the fourth shaft 823 to rotate, and the fourth shaft 823 drives the first bevel gear 826 to rotate. Since the first bevel gear 826 is meshed with the second bevel gear 829, the first bevel gear 826 drives the second bevel gear 829 to rotate, thereby rotating the fifth shaft 828, and the fifth shaft 828 drives the first sprocket 8211 and the third sprocket 8217 to rotate. Rotate, the first sprocket 8211 rotates through the cooperation of the first chain 8216, thereby driving the first roller 8212 to rotate, and the third sprocket 8217 rotates the fourth sprocket 8218 through the cooperation of the second chain 8219, thereby driving the second roller 8213 to rotate, the first roller 8212 and the second roller 8213 rotate in the same direction so that the conveyor belt 8214 moves forward, thereby driving the sampling bottle to move forward, when the moving bottle moves to the bottom of the metal water pipe 6, the valve 5 will open, and the urea solution in the first box 2 will be discharged into the sampling bottle, when the sampling bottle is about to leave the bottom of the metal water pipe 6, the valve 5 will close. The device can fill multiple sampling bottles with urea solution, which can make the urea solution experiment more accurate;

[0057] Start the temperature control device 94 to make the temperature control tube 93 in the second box 91 work, so that the temperature in the second box 91 is maintained at about 20 degrees. Then start the fan 92 to suck the outside air into the second box 91 to keep the air at about 20 degrees.
