[0024] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the solution of the present utility model will be further described below. It should be noted that, without conflict, the implementation manners of the present utility model and the features in the implementation manners can be combined with each other.
[0025] Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein; obviously, the implementation manners in the specification are only a part of the implementation manners of the present utility model, rather than all of the implementation manners.
[0026] Combined with Figures 1 to 5As shown in the figure, the rice bin radar level gauge provided by the embodiment of the present utility model includes a radar level device 4 installed at the upper end inside the rice bin body 1, and a precise level auxiliary mechanism 5, which is installed inside the rice bin body 1 in a lifting manner. A wave-passing opening blocking mechanism 53 is installed on the movable end of the precise level auxiliary mechanism 5. An opening 536 is provided at the output end of the precise level auxiliary mechanism 5. The output end of the wave-passing opening blocking mechanism 53 blocks the opening 536. After the opening 536 is blocked, the precise level auxiliary mechanism 5 descends to flatten the upper surface of the rice pile. After the rice pile is flattened, the precise level auxiliary mechanism 5 ascends. After the precise level auxiliary mechanism 5 ascends, the movable end of the wave-passing opening blocking mechanism 53 leaves the opening 536. The radar level device 4 emits electromagnetic waves, passes through the opening 536, reaches the upper surface of the rice pile, and then returns along the original path through reflection.
[0027] Thus, the top of the rice pile is flattened by the precise level auxiliary mechanism 5 to make the height uniform. Then, the wave-passing opening blocking mechanism 53 cancels the blockage of the upper plate of the precise level auxiliary mechanism 5, so that the electromagnetic waves emitted by the radar level gauge move to the flattened rice pile, and after reflection, return along the original path to complete the measurement. It realizes the measurement after the height of the top of the rice pile is made uniform, reduces the error of the measurement result, and improves the work quality.
[0028] In some embodiments, as Figure 1 shown, the precise level auxiliary mechanism 5 includes two cylinders 51, which are symmetrically installed on the upper surface inside the rice bin body 1. The output ends of the two cylinders 51 are fixedly connected with a pressure plate 52. The opening 536 is provided on the pressure plate 52. The wave-passing opening blocking mechanism 53 is installed on the pressure plate 52.
[0029] Thus, when the rice pile needs to be flattened, the cylinders 51 are started to drive the pressure plate 52 to descend to flatten the rice pile inside the rice bin body 1, and then the pressure plate 52 is raised after flattening.
[0030] In some embodiments, as Figure 1 、 Figure 3 and Figure 5 shown, the wave-passing opening blocking mechanism 53 includes a slow-speed motor 531, which is fixedly connected to the upper surface of the pressure plate 52. The output end of the slow-speed motor 531 is fixedly connected with a connecting plate 532. A micro-cylinder 533 is vertically installed on the lower surface of the connecting plate 532. The telescopic end of the micro-cylinder 533 is fixedly connected with a closing block 534, and the side wall of the closing block 534 fits with the inner wall of the opening 536 after descending.
[0031] Thus, after the rice is conveyed from the feed inlet 2 into the rice bin body 1, the slow motor 531 is started to rotate, which in turn drives the connecting plate 532 to rotate so that the closing block 534 on the telescopic end of the micro cylinder 533 is aligned with the opening 536. Subsequently, the micro cylinder 533 is started to lower the closing block 534 until the closing block 534 is completely attached to the opening 536, and then flattening is carried out. After flattening, the closing block 534 is raised, and the slow motor 531 is started to rotate to drive the connecting plate 532 to rotate, so that the opening 536 is communicated with the radar level device 4 in the rice bin body 1.
[0032] Wherein, the closing block 534 and the pressing plate 52 are made of the same material. A protruding limiting edge 535 is provided at the edge of the upper end of the closing block 534, and a protruding limiting edge mounting groove 537 is formed at the edge of the upper end of the opening 536. After the protruding limiting edge 535 descends, it enters the protruding limiting edge mounting groove 537.
[0033] Thus, by completely entering the protruding limiting edge mounting groove 537, the closing block 534 is limited to prevent the closing block 534 from moving beyond or not reaching the plane of the pressing plate 52, resulting in uneven flattening in the subsequent process.
[0034] In some embodiments, as Figure 2 and Figure 4 shown, a dust collection mechanism 6 and a constant temperature mechanism 7 are fixedly connected to the rice bin body 1. The dust collection mechanism includes a dust collection pipe 61, one end of which is fixedly connected to a dust collector 62, and the other end of the dust collection pipe 61 is fixedly connected to the outer wall of the rice bin body 1. A filter screen 63 is installed at the connection of the dust collection pipe 61 and the outer wall of the rice bin body 1. The constant temperature mechanism 7 includes an air delivery pipe 71, one end of which is fixedly connected to a hot and cold air blower 72, and the other end of the air delivery pipe 71 is fixedly connected to the outer wall of the rice bin body 1. A ventilation net 73 is installed at the connection of the air delivery pipe 71 and the outer wall of the rice bin body 1. A temperature sensor 74 is installed in the rice bin body 1, and the temperature sensor 74 is electrically connected to the hot and cold air blower 72.
[0035] Wherein, a viewing window 8 is formed on the rice bin body 1, and a baffle 81 is detachably connected to the rice bin body 1 outside the viewing window 8.
[0036] Thus, while the radar level device 4 is working, the dust collection mechanism 6 and the constant temperature mechanism 7 are started to prevent the dust and temperature in the rice bin body 1 from affecting the propagation of electromagnetic waves.
[0037] The following combines the attached Figures 1 - 5 to describe a specific embodiment of the present invention:
[0038] As Figures 1 - 5As shown in the figure, a radar level device 4 is installed at the upper end inside the rice bin body 1, and a precise level auxiliary mechanism 5 is installed inside the rice bin body 1 in a lifting manner. A wave-penetrating opening plugging mechanism 53 is installed at the movable end of the precise level auxiliary mechanism 5. An opening 536 is provided at the output end of the precise level auxiliary mechanism 5, and the output end of the wave-penetrating opening plugging mechanism 53 plugs the opening 536. After the opening 536 is plugged, the precise level auxiliary mechanism 5 descends to flatten the upper surface of the rice pile. After flattening the rice pile, the precise level auxiliary mechanism 5 ascends. After the precise level auxiliary mechanism 5 ascends, the movable end of the wave-penetrating opening plugging mechanism 53 leaves the opening 536. The radar level device 4 emits electromagnetic waves, which pass through the opening 536 to reach the upper surface of the rice pile and then return along the original path through reflection.
[0039] During actual use, after the rice is conveyed from the feed inlet 2 into the rice bin body 1, the slow-speed motor 531 is started to rotate, which in turn drives the connecting plate 532 to rotate so that the closing block 534 on the telescopic end of the micro cylinder 533 aligns with the opening 536. Subsequently, the micro cylinder 533 is started to lower the closing block 534 until the closing block 534 completely fits with the opening 536. At this time, the cylinder 51 is started to drive the pressing plate 52 to descend to flatten the rice pile in the rice bin body 1. After flattening, the pressing plate 52 is raised, and the closing block 534 is raised. The slow-speed motor 531 is started to rotate to drive the connecting plate 532 to rotate, so that the opening 536 communicates with the radar level device 4 in the rice bin body 1. At this time, the radar level device 4 is started to emit electromagnetic waves that pass through the opening 536 to contact the top surface of the rice pile. After contact, the waves are reflected back along the original path to measure the height of the rice pile. At the same time, during the operation of the radar level device 4, the dust collection mechanism 6 and the constant temperature mechanism 7 are started to prevent the dust and temperature in the rice bin body 1 from affecting the propagation of electromagnetic waves, realizing the measurement after the height of the top of the rice pile is made uniform, reducing the error of the measurement result, and improving the work quality.
