[0002] Expansive agent is a chemical substance used to increase the volume of materials and improve their properties. The main application direction of expansive agent is the construction industry. As an important additive to concrete, it plays a role in improving the volume and performance of concrete. The amount of expansive agent added is relatively strict. Adding too much or too little will significantly change the performance of concrete, causing the concrete to fail to meet regulations and a decline in building quality.

[0003] At present, the ratio of concrete and expansive agent is usually accurately mixed at the concrete station through an automatic weighing device and then made into concrete, which is then transported by concrete mixer trucks. However, not all construction sites can accommodate large concrete mixer trucks. Therefore, in the actual construction process, it is sometimes necessary to mix the concrete on site, which is often done by manual weighing. The weighing results are often inaccurate due to factors such as personnel and equipment, which can easily lead to inaccurate dosage of the expansive agent. Utility Model Content

[0021] 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.

[0022] like Figure 1-3 As shown, an automatic weighing and discharging system for expansion agent is provided. The equipment is supported by a hand-pushed mobile base 1, and a support frame 2 is arranged on the mobile base 1. The support frame 2 is a structure for fixing a rotating shaft 3, and a part of the support frame 2 protrudes from the mobile base 1, so that the support frame 2 can ensure the posture of the weighing bucket 4 when cooperating with the weighing bucket 4.

[0023] Specifically, a weighing bucket 4 is provided on the mobile base 1, and a rotating sleeve 5 is provided on the outside of the weighing bucket 4. The rotating sleeve 5 is provided with a rotating hole on one side thereof and is sleeved on the rotating shaft 3, so that the weighing bucket 4 can be rotated on the rotating shaft 3 by the rotating sleeve 5, thereby adjusting the posture of the weighing bucket 4. When adding expansion agent to the weighing bucket 4 and transporting, the weighing bucket 4 is tilted horizontally. When weighing and discharging, the weighing bucket 4 is erected to be perpendicular to the horizontal, so as to ensure that the material gathers at the bottom of the weighing bucket 4 under the action of gravity, which is convenient for weighing and discharging.

[0024] An annular pressure plate 6 is protruding from the outside of the weighing barrel 4, and a weighing groove 7 is provided on the rotating sleeve 5. The weighing groove 7 is an annular sleeve sleeve arranged outside the weighing barrel 4. A plurality of weighing sensors 8 are arranged around the weighing groove 7, and the pressure plate 6 is in uniform contact with the plurality of weighing sensors 8.

[0025] In the specific implementation process, a number of weighing sensors 8 arranged in a ring on the weighing groove 7 are in uniform contact with the pressure plate 6. During weighing, the weighing barrel 4 is placed perpendicular to the horizontal so that the pressure plate 6 is evenly pressed on the number of weighing sensors 8. The pressure plate 6 squeezes the weighing sensors 8 under the action of gravity. The weighing sensors 8 convert the pressure into electrical signals. The total weight of the weighing barrel 4 and the expansion agent in the barrel is measured by the number of weighing sensors 8.

[0026] A discharge nozzle 10 is extended from the end of the weighing barrel 4, and a control valve 11 is arranged on the discharge nozzle 10. When discharging materials, the control valve 11 is opened to discharge the materials from the discharge nozzle 10. As the materials flow out, the total weight of the weighing barrel 4 and the materials changes. When the set value is reached, the control valve 11 is closed to complete the quantitative discharging.

[0027] Furthermore, a limiting component 9 is provided on the supporting frame 2 to limit the horizontal angle of the rotating sleeve 5. By limiting the horizontal angle of the rotating sleeve 5, the horizontal angle of the measuring barrel 4 is limited and adjusted. A control panel 12 is provided on one side of the supporting frame 2, which is respectively connected to the control valve 11 and several weighing sensors 8, so as to facilitate the adjustment of the discharge amount.

[0028] Furthermore, the weighing barrel 4 is a tubular structure body and a conical structure guide port is provided at one end of the tubular structure body and is connected to the discharge nozzle 10. The material can be evenly concentrated to one side of the discharge port through the guide port. A closed cover plate is provided at the other end of the tubular structure body of the weighing barrel 4, and the material can be added to the weighing barrel 4 by switching the closed end cover.

[0029] Furthermore, a limiting ring plate 13 is fixed by screws on one side of the opening of the weighing slot 7 on the rotating sleeve 5, and the limiting ring plate 13 is used to limit the pressure plate 6 to prevent the weighing bucket 4 from leaving the weighing slot 7.

[0030] Furthermore, one end of the weighing bucket 4 passes through the weighing slot 7 , and the diameter of the weighing bucket 4 matches the inner diameter of the limiting ring plate 13 .

[0031] Furthermore, the mobile base 1 is a trolley with at least one pair of rollers. A rotating groove is provided on the mobile base 1, and the width of the rotating groove matches the diameter of the weighing bucket 4, so as to facilitate moving the weighing bucket 4 and complete material transfer.

[0032] Furthermore, the limiting assembly 9 includes a pair of limiting arc grooves 901, a pair of limiting plates are symmetrically arranged on the support frame 2, a pair of limiting arc grooves 901 are opened on the pair of limiting plates, a pair of limiting screws 902 are respectively arranged on both sides of the rotating sleeve 5 to penetrate the pair of limiting arc grooves 901, and a pair of limiting screws 902 are sleeved with limiting knobs 903 to fit outside the limiting plates;

[0033] In the specific implementation process, a pair of limiting arc grooves 901 on the support frame 2 are used to match the movement trajectory of a pair of limiting screws 902. During the posture adjustment process of the weighing bucket 4, the pair of limiting screws 902 change position with the rotating sleeve 5. After the weighing bucket 4 moves into place, the limiting knob 903 is threadedly connected to the limiting screw 902 to reversely pull and limit the weighing bucket 4.

[0034] The automatic weighing and discharging system for the expansion agent uses a small wheelbarrow as a mobile chassis, which is convenient for transportation at the construction site. The weighing barrel 4, which is assisted by a limit component 9 to control the posture, is used as a container to carry the expansion agent. The limit component 9 can be used to flexibly adjust the posture of the weighing barrel 4, fill in the horizontal state, and discharge in the vertical state. The weighing sensor 8 can be used to accurately measure the discharge amount of the expansion agent. It is suitable for temporary proportioning of concrete on site, with precise control and simple structure.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
