Description

Technical Field

[0001] The utility model relates to the technical field of admixture scales, in particular to an admixture scale for a concrete mixing station with a sealing structure. Background Art

[0002] In recent years, various provinces, cities and regions in my country have increasingly higher requirements for the accuracy of material proportions in concrete mixing plants, especially the accuracy requirements for admixture scales in concrete mixing plants. The original mixing plant admixture scales used a starting butterfly valve for unloading.

[0003] Since the admixture scale is relatively sticky and easily sticks to materials, the butterfly valve will not be closed tightly after starting the material, resulting in leakage and inaccurate measurement. The accuracy of the admixture scale in the mixing station directly affects the quality of concrete and the service life of the construction building.

[0004] For example, the concrete mixing station admixture scale sealing device disclosed in Chinese patent CN214644802U adds a cone plugging rod cylinder device to the original mixing station admixture scale discharge port, ensuring the accurate metering accuracy of the mixing station admixture scale, solving the shortcomings of leakage and loose door when the admixture scale is discharged with a butterfly valve, and ensuring the quality of concrete. Ensure that the mixing and construction site environment is pollution-free, bringing people a green, environmentally friendly and beautiful living environment. It meets the overall green requirements of harmlessness, pollution-free and resource utilization of national environmental protection.

[0005] However, the upper end of the admixture scale is not provided with a feeding structure, and the scale body needs to be disassembled for filling, which is very inconvenient.

[0006] For this reason, we urgently need to provide a concrete mixing station admixture scale with a feeding structure and a sealing structure. Utility Model Content

[0007] The utility model aims to provide a concrete mixing station admixture scale with a sealing structure to solve the problem that the admixture scale proposed in the above background technology has no feeding structure at the upper end and needs to disassemble the scale body for filling, which is very inconvenient.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete mixing station admixture scale with a sealing structure, comprising a bracket and a weighing sensor, wherein the weighing sensor is arranged at the top end of the bracket, a connecting frame is arranged at the lower end of the weighing sensor, a hanging ring is fixedly connected to the upper middle position of the connecting frame, hooks are fixedly connected to the right side of the lower side of the upper end of the bracket and the upper and lower ends of the weighing sensor, a tank cover is fixedly connected to the lower end of the connecting frame, a scale body is fixedly connected to the inner and outer ends of the scale body with an adding mechanism, the adding mechanism comprises a feeding unit and a sealing unit, the feeding unit is arranged at the upper end of the tank cover, and the sealing unit is arranged at the inner and outer ends of the scale body.

[0009] The feeding unit includes a feed hopper, a connecting plate, a round shaft, a sealing plate, a handle, a round rod, a round plate, a spring, a clamping plate and a clamping rod.

[0010] A further improvement is that the hook at the upper end of the weighing sensor is hung on the hook at the upper end of the bracket, and the hanging ring on the connecting frame is hung on the hook at the lower end of the weighing sensor, so that the body can be suspended symmetrically through the hook.

[0011] A further improvement is that a rotating hole is opened at the inner right end of the sealing plate, the outer side of the circular axis is rotatably connected to the inner side of the rotating hole, and the front and rear sides of the right end of the sealing plate are slidingly connected to the adjacent sides of the two connecting plates, so that the sealing plate can be rotated around the circular axis.

[0012] A further improvement is that a limiting hole is provided at the inner lower end of the clamping plate, and the outer side of the round rod is slidably connected to the inner side of the limiting hole, so that when the spring is activated, the clamping plate can be driven to slide along the outer side of the round rod.

[0013] A further improvement is that a card hole is provided at the inner upper end of the card plate, the outer side of the card rod is slidably connected to the inner side of the card hole, and the lower side of the sealing plate abuts against the upper side of the feed hopper, so that after the sealing plate is rotated to the upper end of the feed hopper around the circular axis, the card plate is pushed to the right by the spring rebound, so that the card hole on the upper end of the card plate slides to the outer side of the card rod, so that the card plate and the card rod can be relatively fixed.

[0014] A further improvement is that the sealing unit includes a support frame, a telescopic member, a connecting rod and a sealing plug, the support frame is fixedly connected to the upper middle position of the tank cover, the telescopic member is fixedly connected to the upper middle position of the support frame, the connecting rod is fixedly connected to the lower end of the output shaft of the telescopic member, and the sealing plug is fixedly connected to the lower end of the connecting rod.

[0015] A further improvement is that the outer side of the sealing plug abuts against the inner bottom end of the scale body, thereby starting the telescopic member and moving its output shaft downward to drive the connecting rod and the sealing plug downward, so that after the outer side of the sealing plug abuts against the inner bottom end of the scale body, the lower end of the scale body can be sealed.

[0016] In summary, the present application discloses a concrete mixing station admixture scale with a sealing structure.

[0017] According to the technical solution, after the clamping plate is pulled to the left so that its upper end is no longer located outside the clamping rod, the handle is pulled up to drive the sealing plate to rotate around the circular axis away from the upper end of the feed hopper, so that material can be added to the interior of the symmetrical body.

[0018] Furthermore, by starting the telescopic member and moving its output shaft downward, the connecting rod and the sealing plug are driven downward, so that the outer side of the sealing plug abuts against the inner bottom end of the scale body, and the lower end of the scale body can be sealed.

[0027] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0028] Embodiment 1:

[0029] A concrete mixing station admixture scale with a sealing structure includes a bracket 1 and a weighing sensor 2. The weighing sensor 2 is arranged at the top of the bracket 1. A connecting frame 3 is arranged at the lower end of the weighing sensor 2. A hanging ring 4 is fixedly connected to the middle position of the upper side of the connecting frame 3. A hook 5 is fixedly connected to the lower right side of the upper end of the bracket 1 and the upper and lower ends of the weighing sensor 2. A tank cover 6 is fixedly connected to the lower end of the connecting frame 3. A scale body 7 is fixedly connected to the lower end of the tank cover 6. The hook 5 at the upper end of the weighing sensor 2 is hung on the hook at the upper end of the bracket 1. The hanging ring 4 on the connecting frame 3 is hung on the hook at the lower end of the weighing sensor 2. Thus, the symmetrical body 7 can be hung through the hook.

[0030] The inner and outer ends of the weighing body 7 are connected with a adding mechanism, which includes a adding unit and a sealing unit. The adding unit is arranged at the upper end of the tank cover 6, and the sealing unit is arranged at the inner and outer ends of the weighing body 7.

[0031] The feeding unit includes a feed hopper 801, a connecting plate 802, a circular shaft 803, a sealing plate 804, a handle 805, a circular rod 806, a circular plate 807, a spring 808, a clamping plate 809 and a clamping rod 810. The feed hopper 801 is fixedly connected to the upper left end of the inner part of the tank cover 6, the connecting plate 802 is fixedly connected to the right side of the front and rear sides of the upper end of the feed hopper 801, the circular shaft 803 is fixedly connected to the upper ends of the adjacent sides of the two connecting plates 802, the sealing plate 804 is connected to the outer end of the circular shaft 803, a rotating hole is opened at the inner right end of the sealing plate 804, the outer side of the circular shaft 803 is rotatably connected to the inner side of the rotating hole, and the front and rear sides of the right end of the sealing plate 804 are slidably connected to the adjacent sides of the two connecting plates 802. Thus, the sealing plate 804 can be rotated around the circular shaft 803.

[0032] The handle 805 is fixedly connected to the middle position of the upper left end of the sealing plate 804, the round rod 806 is fixedly connected to the middle position of the upper left end of the feed hopper 801, the round plate 807 is fixedly connected to the left side of the round rod 806, the spring 808 is fixedly connected to the right side of the round plate 807, the clamping plate 809 is fixedly connected to the right end of the spring 808, and the clamping rod 810 is fixedly connected to the middle position of the left side of the sealing plate 804. A limiting hole is provided at the lower end of the clamping plate 809, and the outer side of the round rod 806 is slidably connected to the inner side of the limiting hole. Therefore, when the spring 808 bounces, the clamping plate 809 can be driven to slide along the outer side of the round rod 806, thereby limiting the movement of the clamping plate 809.

[0033] A clamping hole is provided at the upper end of the clamping plate 809, and the outer side of the clamping rod 810 is slidably connected to the inner side of the clamping hole, and the lower side of the sealing plate 804 abuts against the upper side of the feed hopper 801.

[0034] Embodiment 2:

[0035] On the basis of Example 1: the sealing unit includes a support frame 901, a telescopic member 902, a connecting rod 903 and a sealing plug 904, the support frame 901 is fixedly connected to the upper middle position of the tank cover 6, the telescopic member 902 is fixedly connected to the upper middle position of the support frame 901, the connecting rod 903 is fixedly connected to the lower end of the output shaft of the telescopic member 902, and the sealing plug 904 is fixedly connected to the lower end of the connecting rod 903.

[0036] The outer side of the sealing plug 904 abuts against the inner bottom end of the scale body 7. Thus, the output shaft of the telescopic member 902 is started to move downward, driving the connecting rod 903 and the sealing plug 904 to move downward, so that the outer side of the sealing plug 904 abuts against the inner bottom end of the scale body 7, and the lower end of the scale body 7 can be sealed.

[0037] Working principle: When in use, start the telescopic member 902 and its output shaft is recovered to drive the connecting rod 903 and the sealing plug 904 to move upward. The sealing plug 904 no longer contacts the inner bottom end of the scale body 7, and the material in the scale body 7 is discharged from the lower end of the scale body 7 for feeding. After the feeding is completed, start the telescopic member 902 again to release the output shaft, drive the connecting rod 903 and the sealing plug 904 to move downward, so that the sealing plug 904 moves to contact the inner bottom end of the scale body 7, closes the lower end of the scale body 7, and re-closes the scale body 7.
