Description

Technical Field

[0001] The present application relates to the technical field of concrete mixing, and in particular to a concrete mixing device with a powder feeding device. Background Art

[0002] Concrete is a general term for engineering composite materials that are bonded together by cementitious materials. The term concrete usually refers to cement concrete obtained by mixing cement as a cementitious material, sand and stone as aggregates and water in a certain proportion. It is also called ordinary concrete. It is widely used in civil engineering. Concrete has the characteristics of abundant raw materials, low price and simple production process, which makes its usage more and more. At the same time, concrete also has the characteristics of high compressive strength, good durability and a wide range of strength grades. These characteristics make its scope of use very wide. It is not only used in various civil engineering projects, but also in shipbuilding, machinery industry, marine development and geothermal engineering. Concrete is also an important material.

[0003] The existing patent (publication number: CN215702818U) discloses a powder feeding device for a concrete mixing station, including a mixing tank and a motor, wherein the motor is fixedly connected to the bottom of the mixing tank, the output shaft of the motor passes through the mixing tank, the output shaft of the motor is fixedly connected to a rotating rod, and the part of the rotating rod close to the bottom of the mixing tank is fixedly connected to a mixing fan blade.

[0004] The above-mentioned comparative document points out that the device can put bags of cement into the loading barrel, use the blade in the loading barrel to cut the cement bag, and then use the centrifugal force generated by the rotation of the loading barrel to send the cement powder from multiple circular holes to the mixing tank, so as to facilitate the staff to load the cement, and there is no need for the staff to manually cut the cement bag to avoid the cement powder from endangering the health of the staff. At the same time, the cement is evenly sent to the mixing drum through multiple circular holes, which can avoid cement agglomeration and facilitate cement mixing. However, when feeding, the device puts the whole bag of cement into the loading barrel, cuts the cement bag with a blade, and then the whole bag of cement enters the mixing tank. The feeding amount cannot be well controlled, and the blade cuts the cement bag, which may cause debris in the cement bag, which then enters the inside of the mixing tank, thereby affecting the quality of the concrete. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a concrete mixing device with a powder feeding device, which has the advantage of being able to control the feeding amount, and solves the problem that when the device is feeding, a whole bag of cement is placed in a loading bucket and the cement bag is cut open by a blade, and then the whole bag of cement enters the mixing tank, and the feeding amount cannot be well controlled. In addition, since the cement bag is cut open by the blade, debris may be generated in the cement bag, which then enters the inside of the mixing tank and affects the quality of the concrete.

When the specified weight is reached, the electric push rod contracts and pulls the weighing module and the supporting plate to flip downward through the hinge, so that the cement falls into the mixing tank. By setting the weighing module, the device can monitor the weight of the powder added to the mixing tank in real time, thereby ensuring that the proportion of concrete mixed each time is accurate and the quality stability of the concrete is improved.

[0008] Furthermore, a feed box is fixedly connected to the upper end of the weighing box, and a feed port is opened through one side of the feed box.

[0009] Through the above scheme, the feed port is configured to lift the cement through the feeding device, enter the box through the feed port, and let the cement fall into the weighing box through the slope at the bottom of the feed box.

[0010] Furthermore, two fixed plates are fixedly connected to one side of the weighing box, and a feed pipe is fixedly connected to one end of the two fixed plates away from the weighing box. A discharge port is provided at the upper end of the outer wall of the feed pipe, and a first motor is fixedly connected to the upper end of the feed pipe. The output end of the first motor passes through the feed pipe and is fixedly connected to a screw via a coupling.

[0011] Through the above scheme, through the combination of the first motor and the screw, the device can realize automatic feeding, and the first motor drives the screw to rotate to lift the cement, and discharges the cement through the discharge port and enters the feed box through the feed port.

[0013] Through the above solution, the second motor drives the rotating shaft and the stirring blades to rotate, which can ensure that the cement in the mixing tank is evenly stirred.

[0014] Furthermore, a discharge pipe is fixedly connected to the bottom end of the mixing tank, and a stop valve is fixedly sleeved outside the discharge pipe.

[0015] Through the above scheme, a discharge pipe and a stop valve are arranged at the bottom of the mixing tank, which can conveniently control the discharge of concrete to meet different production needs.

[0016] Furthermore, a control box and a fixed block are fixedly connected to the outer wall of the stirring tank, and a side of the fixed block away from the stirring tank is fixedly connected to the feed pipe.

[0017] Through the above solution, the fixing block is used to further fix the feeding pipe.

[0018] Furthermore, four legs are fixedly connected to the bottom end of the mixing tank.

[0019] With the above solution, the legs are used to support the device.

[0020] Furthermore, a charging box is arranged at the bottom end of the feeding tube, and the feeding tube is fixedly arranged inside the charging box.

When the specified weight is reached, the electric push rod contracts and pulls the weighing module and the supporting plate to flip downward through the hinge, so that the cement falls into the mixing tank. The device can monitor the weight of the powder added to the mixing tank in real time by setting the weighing module, thereby ensuring that the proportion of concrete mixed each time is accurate and the quality stability of the concrete is improved.

Through the combination of the first motor 15 and the screw 14, the device can realize automatic feeding, and the first motor 15 drives the screw 14 to rotate to lift the cement, and the cement is discharged through the discharge port 13, and enters the feed box 9 through the feed port 10.

[0033] See also Figure 1 and Figure 4 The upper end of the mixing tank 1 is fixedly connected to a second motor 16, the output end of the second motor 16 penetrates the mixing tank 1 and is fixedly connected to a rotating shaft 17 through a coupling, and a stirring blade 18 is fixedly connected to the bottom end of the rotating shaft 17.

[0034] In this embodiment, the concrete mixing device with a powder feeding device is arranged through a weighing box 2, a supporting plate 5, a hinge 3, a first rotating seat 6, a second rotating seat 7 and an electric push rod 8. When in use, cement enters the weighing box 2 through the feeding device and falls on the upper end of the supporting plate 5. The weight is monitored in real time by the weighing module 4, thereby ensuring that the proportion of concrete mixed each time is accurate and the quality stability of the concrete is improved. When the specified weight is reached, the electric push rod 8 contracts and pulls the weighing module 4 and the supporting plate 5 to flip downward through the hinge 3, so that the cement falls into the mixing tank 1.

[0036] The working principle of the above embodiment is:

[0037] The staff puts cement into the feed box 9 through the feeding device, and drives the screw 14 to rotate inside the feed pipe 12 through the first motor 15 to lift the cement, so that the cement enters the weighing box 2 through the feed port 10 and falls on the supporting plate 5. The weighing module 4 monitors the weight of the cement on the supporting plate 5 in real time and transmits the data to the control box 21 for display. When the cement reaches the specified weight, the control box 21 sends a signal, and the electric push rod 8 begins to shrink. The electric push rod 8 pulls the weighing module 4 and the supporting plate 5 through the first rotating seat 6 and the second rotating seat 7. Due to the presence of the hinge 3, the supporting plate 5 and the weighing module 4 flip downward, so that the cement slides from the supporting plate 5 and falls into the mixing tank 1. After the cement enters the mixing tank 1, the second motor 16 is started, and the second motor 16 drives the rotating shaft 17 and the stirring blade 18 to rotate, so as to evenly stir the cement in the mixing tank 1. When discharging is required, the staff operates the control box 21 to open the stop valve 20, and the concrete in the mixing tank 1 is discharged through the discharge pipe 19.
