[0030] Combine Figures 1 to 5 As shown, the electronic scale for weighing rice provided by the present invention includes an electronic scale 1, a rated feeder 2 and an auxiliary feeder 3.
[0031] Combine Figures 1 to 5 As shown, a measuring hopper 11 is fixedly connected to the scale pan of the electronic scale 1; a rated storage chamber is provided in the rated feeder 2, the single discharge amount of the rated feeder 2 is the same as the capacity of the rated storage chamber, and the discharge port of the rated feeder 2 is facing the measuring hopper 11; the auxiliary feeder 3 includes an auxiliary feeder pipe 31 and an auxiliary feeder valve 32, the auxiliary feeder valve 32 is assembled on the discharge port of the auxiliary feeder pipe 31, and the discharge port of the auxiliary feeder 3 is facing the measuring hopper 11.
[0032] In this embodiment, there are two feeders. The rated feeder 2 adopts a large diameter to ensure the addition speed, and at the same time reduces the addition error by designing the rated storage chamber; the auxiliary feeder 3 adopts a small diameter to ensure the addition accuracy, and cooperates with the electronic scale 1 to realize accurate and efficient addition of rice into the vector hopper 11.
[0033] In some embodiments, combined Figure 3 、 Figure 4 As shown, the rated discharger 2 includes a discharge tube 21, a partition 22 and a dividing plate 23. The dividing plate 23 is vertically rotatably assembled in the discharge tube 21. There are two partitions 22. The two partitions 22 are distributed up and down and fixedly assembled in the discharge tube 21. The partition 22 is provided with a discharge hole, and the two discharge holes are staggered up and down. The dividing plate 23 is composed of a rotating shaft and a rectangular plate. The rectangular plates are evenly distributed on the cylindrical surface of the rotating shaft. The dividing plate 23 is rotatably assembled between the two partitions 22. The dividing plate 23 divides the space between the two partitions 22 into multiple rated storage chambers.
[0034] In this embodiment, a fixed volume of rice is added through the rated feeder 2, the adding efficiency is high, and the error of adding is small. In conjunction with the auxiliary feeder 3, the adding task can be completed efficiently and accurately. The volume of rice that the rated storage chamber can accommodate at a single time can be slightly smaller than the planned integer volume, and then it is replenished by the auxiliary feeder 3, which can effectively avoid the problem of excessive addition.
[0035] In some embodiments, combined Figure 4 As shown, four rectangular plates are evenly distributed on the cylindrical surface of the rotating shaft, and the shape of the blanking hole is a 90-degree sector. In order to ensure the size of a single rated storage chamber, the more rectangular plates there are on the cylindrical surface of the rotating shaft, the larger the overall volume; but when the number is too small, during the movement of the rated storage chamber, it may be connected to the upper and lower blanking holes at the same time, resulting in the accuracy of adding rice being affected. The number of the rated storage chambers must be at least four to avoid the above-mentioned accuracy problems.
[0036] In some embodiments, combined Figure 4 As shown, the rated feeder 2 also includes a vibration generator 24, which is fixedly connected to the outer wall of the feed pipe 21. The vibration generator 24 mainly has two functions. One is to reduce the gaps between rice grains through vibration to ensure the uniformity of rice weight in the rated storage chamber; the other is to avoid blockage problems through vibration to help feed more thoroughly.
[0037] In some embodiments, combined Figure 2 As shown, the bottom plate of the measuring hopper 11 is integrally formed with a funnel, and a gate 12 is fixedly mounted on the outlet of the funnel, which facilitates the transfer of rice. The rice added to the measuring hopper 11 can be quickly transferred to other containers.
[0038] In some embodiments, combined Figure 1 、 Figure 2 As shown, the electronic scale 1 is annular, and the funnel outlet passes through the electronic scale 1 downward. Generally, there is no through hole in the center of the electronic scale 1. The funnel at the measuring hopper 11 needs to be set eccentrically. The eccentric measuring hopper 11 will affect the discharge of rice. At the same time, the center of gravity of the measuring hopper 11 will be offset, which will affect the measurement result of the electronic scale 1. After the electronic scale 1 is annular, the above problems can be effectively avoided.
[0039] In some embodiments, combined Figure 5 As shown, the electronic scale for weighing rice also includes a storage hopper 41, which is located above the rated feeder 2 and the auxiliary feeder 3. The storage hopper 41 is connected to the rated feeder 2 and the auxiliary feeder 3. The storage hopper 41 is used to store rice, and the rated feeder 2 and the auxiliary feeder 3 are used to add the rice in the storage hopper 41 to the measuring hopper 11.
[0040] In some embodiments, combined Figure 5 As shown, the electronic scale for weighing rice also includes a shell 42, which is fixedly connected to the scale body of the electronic scale 1, the measuring hopper 11 is located inside the shell 42, and the top of the shell 42 is fixedly connected to the bottom plate of the storage hopper 41. Adding the shell 42 can effectively improve the overall sealing performance and reduce the possibility of impurities entering.
[0041] In some embodiments, combined Figure 5 As shown, the electronic scale for weighing rice also includes an external control center 43, the rated feeder 2 is provided with a motor drive, the feeder valve 32 is a solenoid valve, the external control center 43 is electrically connected to the motor and the feeder valve 32, and the external control center 43 is fixedly connected to the outer wall of the shell 42. The operator can control the rated feeder 2 and the auxiliary feeder 3 through the external control center 43 to complete the addition of rice, thereby reducing the difficulty of operation for the operator.
[0042] In some embodiments, combined Figure 5 As shown, the display of the electronic scale is integrated into the external control center 43, which can effectively facilitate the operator to observe the measurement results of the electronic scale when adding rice.
[0043] Working process: After determining the target amount of rice to be added, the rated feeder 2 is started until the remaining amount to be added is less than the rated storage chamber capacity; the rated feeder 2 is closed and the auxiliary feeder 3 is started. The auxiliary feeder valve 32 can control the conduction state of the auxiliary feeder pipe 31 until the addition of rice is completed; during the addition process, the reading of the electronic scale 1 is checked to determine the addition progress.
[0044] In the rated feeder 2, rice enters the rated storage chamber through the upper discharge hole and is discharged from the rated storage chamber through the lower discharge hole. The rotation of the dividing plate 23 can change the position of the rated storage chamber to realize the feeding and discharging of the rated storage chamber. The multiple rated storage chambers are independent of each other, and while one of them is discharging, another rated storage chamber will also be feeding.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
