Description
Technical Field
[0001] The utility model relates to the technical field of loss-in-weight scales, in particular to a fertilizer loss-in-weight scale. Background Art
[0002] In the process of high-precision continuous quantitative feeding of fertilizers, loss-in-weight scales are used. Through static weighing, fertilizers can be fed reliably, accurately and stably, effectively reducing fertilizer waste and improving the efficiency and quality of agricultural production.
[0003] When fertilizer flows out of the loss-in-weight scale, the control system will collect the weight signal of the scale body at high speed and high frequency, and obtain the weight reduction of the fertilizer in the measuring bucket per unit time. Then, through specific filtering and optimization processing, the actual flow rate of the loss-in-weight scale is calculated and compared with the preset given speed. According to the comparison result, the control system will automatically correct the feeding speed of the feeding mechanism to form a closed-loop control so that the actual flow rate is infinitely close to the given flow rate. The silo of some existing loss-in-weight scales is supported and installed in the bracket by the weighing module, so that the weighing module supporting the silo is used to monitor the weight of the silo in real time. After the support screw of the weighing module supporting the silo is leveled, in the later use, due to factors such as vibration, temperature change or material flow, the adjusting nut of the support screw of the weighing module may rotate. This rotation will cause the support screw to move, resulting in uneven force on the weighing module, affecting the weighing accuracy and stability. Utility Model Content

[0022] like Figure 2-Figure 5As shown, a rotation groove 14 is provided on the outer side of the guide seat 13, a displacement groove 15 is provided on the outer side of the guide seat 13 located below the rotation groove 14, and a plurality of slots 16 are provided on the top of the displacement groove 15. A sleeve 18 is fixedly installed on the lower end of the adjusting nut 10, and a fixing ring 19 is fixedly installed on the inner side of the sleeve 18. The adjusting nut 10 is rotatably installed on the guide seat 13 through the sleeve 18, and the fixing ring 19 is rotatably installed in the rotation groove 14. The adjusting nut 10 is rotatably installed on the guide seat 13 through the sleeve 18 and the fixing ring 19, which can facilitate the adjustment of the height of the supporting seat 7. The limiting ring A plurality of tooth blocks 20 are fixedly installed on the inner side of the limit ring 11, and a linkage seat 21 is fixedly installed on the limit ring 11. The transverse section of the linkage seat 21 is a regular octagon. The limit ring 11 is inserted and installed on the outer side of the guide seat 13. The linkage seat 21 is inserted and installed on the outer side of the adjusting nut 10 and the sleeve 18. The guide seat 13 between the limit ring 11 and the top block 8 is sleeved with a compression spring 17. With the support of the compression spring 17 on the limit ring 11, the limit ring 11 is clamped in the corresponding clamping groove 16 through the plurality of tooth blocks 20 on the inner side, so that the axial movement of the adjusting nut 10 can be limited.
[0023] Embodiment 2, as Figure 2-Figure 3 As shown, a screw rod 24 is fixedly installed at the center position of the lower end of the supporting seat 7, three first fixing seats 22 are fixedly installed on the outer side of the supporting seat 7, the lower end of the screw rod 24 is threadedly connected in the adjusting nut 10 and is inserted and installed in the guide seat 13 and the top block 8, and three second fixing seats 23 are fixedly installed on the outer side of the clip 12. The second fixing seats 23 are fixedly connected to the corresponding first fixing seats 22 by bolts. The side ears 4 can be supported by the supporting seat 7. At the same time, with the setting of the clip 12, the side ears 4 can be clamped and fixed between the supporting seat 7 and the clip 12.
[0024] It should be noted that the utility model is a fertilizer loss-in-weight scale. After the silo 1 is supported and weighed by the weighing sensor 6, the top block 8, the screw rod 24, the supporting seat 7, the clip 12 and the side ear 4, if the installation of the silo 1 is not in a horizontal posture, the adjusting nut 10 on the corresponding side can be rotated, and a hand-held wrench or other tool can be inserted into the outside of the linkage seat 21, and the limit ring 11 can be pressed down by the wrench or other tool, so that the limit ring 11 drives the multiple tooth blocks 20 on the inside to disengage from the corresponding grooves 16 on the outside of the guide seat 13. At this time, the linkage seat 21 also moves downward synchronously with the limiting ring 11, but the linkage seat 21 always remains connected with the adjusting nut 10, and then, the wrench can be rotated, so that the wrench can drive the adjusting nut 10 to rotate through the linkage seat 21, and the adjusting nut 10 simultaneously uses the fixing ring 19 on the inside of the sleeve 18 as the axis. The center of the silo 1 rotates on the guide seat 13, and the adjusting nut 10 also rotates on the outside of the screw rod 24. In addition, since the supporting seat 7 is clamped and fixed on the side ear 4 by the clip 12, the axial movement of the screw rod 24 can be limited. Therefore, the height of the supporting seat 7 can be adjusted by controlling the up and down movement of the screw rod 24 by adjusting the nut 10, so that the height of one side of the silo 1 can be adjusted to achieve the leveling operation of the silo 1. After the adjustment is completed, the wrench can be pulled out from the outside of the linkage seat 21, and then, with the help of the force of the compression spring 17, the limit ring 11 is pushed up, and the multiple tooth blocks 20 on the inside of the limit ring 11 are re-engaged in the corresponding grooves 16, thereby limiting the axial movement of the limit ring 11, thereby limiting the axial movement of the adjusting nut 10 through the limit ring 11 and the linkage seat 21, preventing the adjustment nut 10 from rotating due to vibration and causing the screw rod 24 to be displaced.
