[0024] 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.
[0025] See also Figure 1-4 In this embodiment, a sand-making concrete mixing device with an automatic proportioning function includes a shell 1. Three support rods 2 are installed on the outer surface of the shell 1 for support. A first motor 3 is connected to the top of the shell 1 and is connected to three discharge barrels 601 through a connecting piece. A stirring rod 4 is connected to the inner top wall of the shell 1 for stirring materials for mixing. A discharge pipe 5 is installed at the bottom of the shell 1 for discharging materials. A proportioning component 6 is installed on the top of the shell 1.
[0026] exist Figure 2 , Figure 3 and Figure 4In the embodiment, the proportioning assembly 6 is composed of seven components, namely, a discharge barrel 601, a rotating rod 602, a measuring box 603, a weight sensor 604, a second motor 605, a mixing blade 606 and a mixing funnel 607, to realize the automatic proportioning function. Three discharge barrels 601 are installed on the top of the shell 1 for feeding different materials. The three discharge barrels 601 are internally connected with a rotating rod 602 for connecting the measuring box 603 and the second motor 605. The discharge barrel 601 is internally connected with the measuring box 603, and the top is blocked with an anti-sticking film, and the size is adapted to the size of the discharge barrel 601 for controlling the entry of materials. A weight sensor 604 is installed on the inner bottom wall of the measuring box 603 for measuring the weight of the current material to facilitate subsequent proportioning. Three second motors 605 are installed on the outer surface of the shell 1 for driving the measuring box 603 to rotate. A mixing blade 606 is installed on the outer surface of the stirring rod 4 for preliminarily stirring and mixing the materials. A mixing funnel 607 is installed on the inner wall of the shell 1 to reduce the falling speed of the materials for preliminary mixing.
[0027] exist Figure 2 and Figure 3 In the figure, a signal receiving end and a signal sending end are set, so that after reaching the standard weight, the signal sending end transmits a signal to the signal receiving end through the PLC controller, activates the second motor 605, and drives the measuring box 603 to rotate to a vertical state, so that the material can continue to fall into the interior of the shell 1.
[0028] exist Figure 2 and Figure 4 In the process, the anti-sticking film is used to prevent the material from adhering to the anti-sticking film, which will cause gaps in the materials under each discharge barrel 601, affecting the subsequent mixing process and reducing the quality of the produced products. At the same time, the rotating shaft is used to make the measuring box 603 rotate more stably, which is convenient for users to use.
[0029] It should be noted that this section is intended to provide a background or context for the implementation methods stated in the claims, and detailed descriptions of known functions and known components are omitted. At the same time, fixed and movable installations are determined according to actual application methods. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art because it is included in this section.
[0030] When implementing, follow these steps:
[0031] 1) When in use, first start the weight sensor 604, then put the material through the discharge cylinder 601 onto the top of the anti-sticking film on the measuring box 603;
[0032] 2) Then, when the material quantity meets the compound ratio requirement, the weight sensor 604 will send an electrical signal to the signal receiving end through the signal output end of the PLC controller, so that the signal receiving end activates the second motor 605 to start working;
[0033] 3) Finally, the output shaft of the second motor 605 rotates to drive the rotating rod 602, and the transmission measuring box 603 starts to tip over, so that the measuring box 603 stands upright, so that the shell 1 is connected with the internal space of the discharge barrel 601, and then the output shaft of the first motor 3 is started to rotate, driving the mixing blades 606 and the stirring rod 4 to start the stirring operation.
[0034] To sum up, the sand-making concrete mixing device with automatic proportioning function focuses on the put-in materials by arranging the discharge barrel 601, the measuring box 603, the weight sensor 604 and the second motor 605, so as to facilitate the user to set the measurement threshold of each weight sensor 604 according to the proportioning requirements. After the material weight meets the measurement threshold requirement, the corresponding second motor 605 is automatically started to discharge the material. There is no need for excessive manual operation, which greatly reduces the labor workload, reduces labor costs, improves the proportioning efficiency, increases the production rate, and further facilitates the user's use and operation.
[0035] Moreover, by setting the mixing blades 606 and the mixing funnel 607, the material entering the shell 1 temporarily falls into the mixing funnel 607 and then flows into the shell 1. In this link, the mixing blades 606 can be used for preliminary stirring, so that the material mixing speed is increased, the final stirring and mixing rate is increased, and the production efficiency is improved. At the same time, the mixing blades 606 are fixedly connected to the stirring rod 4 to fully utilize the power of the rotation of the output shaft of the first motor 3, save energy, reduce the cost of use, and solve the problem in the comparative document that the mixing ratio relies on manual experience control, which consumes a long time, slows the material feeding speed, and reduces the efficiency of use.
