DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1 to Figure 4In the embodiment of the utility model, a precise metering system for a concrete weighing bucket includes a mobile frame 1, a support frame 4 is fixedly connected to the mobile frame 1, a first slide groove 5 is arranged in the support frame 4, a first sliding rod 6 is slidably connected in the first slide groove 5, a hopper 7 is rotatably connected to the first sliding rod 6, a second slide groove 8 is arranged on the top of the support frame 4, a second sliding rod 9 is slidably connected in the second slide groove 8, a connecting frame 10 is rotatably connected to the second sliding rod 9, the connecting frame 10 is fixedly connected to the hopper 7, a guide groove 22 is fixedly connected to one side of the second slide groove 8, a fixed frame 21 is fixedly connected to both sides of the support frame 4, a limiting groove 11 is arranged in the fixed frame 21, and a sliding connection 10 is arranged in the limiting groove 11. A lifting baffle 12 is connected, a lifting cylinder 23 is fixedly connected to the lifting baffle 12, a sliding block 13 is slidably connected to the lifting cylinder 23, and the sliding block 13 is fixedly connected to the first sliding rod 6. A spring 14 sleeved on the lifting cylinder 23 is arranged between the sliding block 13 and the lifting baffle 12, and also includes a driving component connected to the lifting baffle 12 for driving the lifting baffle 12 to lift. The utility model first transmits concrete through the feeding belt 24, thereby transmitting the raw materials to the hopper 7. At this time, as the raw materials in the hopper 7 continue to increase, the weight in the hopper 7 gradually increases. At this time, the hopper 7 transfers the materials in the hopper 7 through the first sliding rod 6 and the sliding block 13. The weight directly acts on the spring 14, thereby compressing the spring 14. It can be known from Hooke's law that as the weight in the hopper 7 gradually increases, the compressed distance of the spring 14 increases synchronously and proportionally. At the same time, the hopper 7 drives the second sliding rod 9 to slide and descend in the second slide groove 8 through the connecting frame 10. When the second sliding rod 9 slides to the bottom of the second slide groove 8, the second sliding rod 9 descends under the action of the guide groove 22 and rotates around the first sliding rod 6 as the center, thereby turning the hopper 7 from a horizontal state to a vertical state, thereby directly dumping the raw materials in the hopper 7. After the dumping is completed, the weight of the hopper 7 decreases rapidly, and at this time, the force on the spring 14 decreases rapidly. The spring 14 releases its elastic potential energy and quickly resets. The spring 14 pushes the sliding block 13 to rise. The sliding block 13 drives the hopper 7 to rise through the first sliding rod 6. The hopper 7 is automatically reset under the drive of the guide groove 22 and the second slide groove 8. At the same time, the utility model can drive the lifting baffle 12 to rise and fall through the driving component, so as to adjust the relative distance between the lifting baffle 12 and the sliding block 13, and then adjust the elastic force of the spring 14, that is, the weight required for the hopper 7 to compress the spring 14 by the same distance is adjusted, so as to adjust the mass of the raw materials required for one flip of the hopper 7, and then realize the accurate weighing of the concrete raw materials.
[0019] In one case of this embodiment, see Figure 1 to Figure 4The bottom of the mobile frame 1 is connected with a moving wheel 2, and one side of the mobile frame 1 is fixedly connected with a handle 3. The utility model realizes the free movement of the mobile frame 1 through the mutual cooperation of the moving wheel 2 and the handle 3.
[0020] In one case of this embodiment, see Figure 1 to Figure 4 , scales 20 are provided on both sides of the limit groove 11, and a pointer 19 is fixedly connected to the lifting baffle 12, and the pointer 19 cooperates with the scale 20. The utility model accurately reads the relative height of the lifting baffle 12 through the cooperation between the scale 20 and the pointer 19, so as to accurately measure the compression force of the spring 14.
[0021] In one case of this embodiment, see Figure 1 to Figure 4 The driving assembly includes a mounting seat 16 fixedly connected to the support frame 4, and a bolt 17 is rotatably connected to the mounting seat 16. A threaded barrel 15 is fixedly connected to the lifting baffle 12, and the threaded barrel 15 is threadedly connected to the bolt 17. The bolt 17 passes through the mounting seat 16 and is fixedly connected to a knob 18. The driving assembly drives the bolt 17 to rotate by screwing the knob 18. The bolt 17 drives the threaded barrel 15 to rise and fall along the bolt 17 through the threaded connection with the threaded barrel 15. The threaded barrel 15 drives the lifting baffle 12 to rise and fall, thereby adjusting the relative distance between the lifting baffle 12 and the sliding block 13.
[0022] The working principle of the utility model is as follows: the utility model firstly conveys the concrete through the feeding belt 24, thereby conveying the raw materials into the hopper 7. At this time, as the raw materials in the hopper 7 continue to increase, the weight in the hopper 7 gradually increases. At this time, the hopper 7 directly acts on the spring 14 with the weight in the hopper 7 through the first sliding rod 6 and the sliding block 13, thereby compressing the spring 14. It can be seen from Hooke's law that as the weight in the hopper 7 gradually increases, the compressed distance of the spring 14 increases synchronously and proportionally. At the same time, the hopper 7 drives the second sliding rod 9 to slide and descend in the second slide groove 8 through the connecting frame 10. When the second sliding rod 9 slides to the bottom of the second slide groove 8, the second sliding rod 9 descends under the action of the guide groove 22 and rotates with the first sliding rod 6 as the center, thereby turning the hopper 7 from a horizontal state to a vertical state, thereby directly pouring out the raw materials in the hopper 7, and the pouring is completed. After that, the weight of the hopper 7 is rapidly reduced. At this time, the force on the spring 14 is rapidly reduced, the spring 14 releases its elastic potential energy and quickly resets, the spring 14 pushes the sliding block 13 to rise, and the sliding block 13 drives the hopper 7 to rise through the first sliding rod 6. The hopper 7 is automatically reset under the drive of the guide groove 22 and the second slide groove 8. At the same time, the utility model can drive the bolt 17 to rotate by screwing the knob 18, and the bolt 17 drives the threaded cylinder 15 to rise and fall along the bolt 17 through the threaded connection with the threaded cylinder 15, and the threaded cylinder 15 drives the lifting baffle 12 to rise and fall, thereby adjusting the relative distance between the lifting baffle 12 and the sliding block 13, and then adjusting the elastic force of the spring 14, that is, adjusting the weight required for the hopper 7 to compress the spring 14 by the same distance, thereby realizing the adjustment of the mass of the raw materials required for one flip of the hopper 7, and then realizing the accurate weighing of the concrete raw materials.
