[0005] 2. After the quantitative proportioning is completed, it is necessary to manually adjust for discharging, and at the same time, the materials are not subjected to primary mixing treatment, so the working efficiency is low. Content of the Utility Model

[0006] The utility model provides a concrete quantitative proportioning device, which solves the problems of the quantitative proportioning device proposed in the comparative document that when performing quantitative proportioning, it is necessary to manually adjust the position of the partition plate, and at the same time, it is impossible to quantitatively proportion more than two different materials, so the practicability is low, it is necessary to manually adjust for discharging, and at the same time, the materials are not subjected to primary mixing treatment, so the working efficiency is low.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A concrete quantitative proportioning device includes a mixing cylinder and a cylinder cover. The upper part of the mixing cylinder is provided with two proportioning mechanisms. Each proportioning mechanism includes a funnel-shaped feed hopper and a storage cylinder fixed to the upper outer wall of the feed hopper. Both sides of the mixing cylinder are provided with mounting mechanisms. Each mounting mechanism includes a mounting plate welded to the upper outer wall of one side of the mixing cylinder and a fixing plate welded to the top outer wall of the mounting plate. Both fixing plates are provided with weighing components. Each weighing component includes a discharge cylinder bolted to the outer wall of one side of the fixing plate, a connecting plate bolted to one end of the piston rod of the discharge cylinder, a fixing frame welded to the outer wall of one side of the connecting plate, and a weighing plate embedded in the fixing frame.

[0009] The mixing cylinder is equipped with a mixing mechanism, which includes a drive shaft that passes through and is connected to the outer wall of the cylinder cover via a bearing, several mixing blades with through holes on the outer wall, and a spiral blade fixed to the lower outer wall of the drive shaft. The top outer wall of the cylinder cover is equipped with a transmission mechanism, which includes a drive motor.

[0010] Preferably, a discharge pipe is fixed on the inner wall of the bottom of the mixing drum, and the drum cover is bolted to the outer wall of the top of the mixing drum.

[0011] Preferably, the feed hopper is inserted through and fixed to the outer wall of the bottom of the cylinder cover, and the lower outer wall of the storage cylinder is provided with a flange, and the middle outer wall of the flange is provided with an installation port.

[0012] Preferably, a support plate is bolted to the bottom outer wall of the mounting plate, and the support plate is welded to the outer wall of one side of the mixing cylinder. Two reinforcing plates are bolted to the outer wall of one side of the fixing plate, and the two reinforcing plates are bolted to the top outer wall of the mounting plate respectively.

[0013] Preferably, the fixed frame is slidably installed in the mounting opening, the weighing plate has an integrated pressure sensor, and the outer diameter of the weighing plate is adapted to the inner diameter of the storage cylinder. Two limiting rods are welded on one side of the outer wall of the connecting plate, and the two limiting rods pass through and are slidably installed on the outer wall of the fixed plate.

[0014] The above scheme stores concrete material in a storage cylinder, while a weighing plate supports and weighs the material. When the material weight reaches a predetermined value, feeding stops. Then, the piston rod of the unloading cylinder moves, causing the fixed frame and the weighing plate to move, so that the weighing plate detaches from the storage cylinder and the material falls into the feeding hopper.

[0015] Preferably, a driven synchronous pulley is connected to the upper outer wall of the drive shaft via a spline, a fixing block is connected to the upper inner wall of the mixing cylinder via bolts, and the upper part of the drive shaft passes through and is connected to the outer wall of the fixing block via a bearing. Several mixing blades are respectively welded to the lower outer wall of the drive shaft, and several mixing blades respectively abut against the inner wall of the mixing cylinder.

[0016] Preferably, a mounting bracket is welded to the top outer wall of the cylinder cover, and the drive motor is bolted to the top outer wall of the mounting bracket. The lower part of the output shaft of the drive motor is connected to a drive synchronizing pulley via a spline, and the drive synchronizing pulley and the driven synchronizing pulley form a transmission engagement via a synchronous belt.

[0017] The above scheme uses the output shaft of the drive motor to rotate, which in turn drives the drive shaft to rotate. The drive shaft then drives multiple mixing blades to rotate, which perform primary mixing of the materials. Subsequently, the rotating spiral blades transport the materials at the bottom of the mixing cylinder.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. The storage cylinder stores concrete materials, while the weighing plate supports and weighs the materials. When the material weight reaches the predetermined value, feeding stops. Then, the piston rod of the unloading cylinder moves, driving the fixed frame and the weighing plate to move, causing the weighing plate to detach from the storage cylinder and the material to fall into the feeding hopper. It can automatically weigh various materials and automatically unload when the weight reaches the target, improving practicality.

[0020] 2. The output shaft of the drive motor rotates, which drives the drive shaft to rotate. The drive shaft drives multiple mixing blades to rotate. The mixing blades perform primary mixing of the materials. Subsequently, the spiral blades rotate to convey the materials at the bottom of the mixing cylinder. This can automatically unload the materials and perform primary mixing of the materials, which is convenient for subsequent stirring and mixing, thus improving work efficiency.

[0021] In summary, this utility model can automatically weigh various materials and automatically unload them when the weight reaches the target, thus improving its practicality. It can automatically unload materials and perform primary mixing, which facilitates subsequent stirring and mixing, thereby improving work efficiency. Attached Figure Description
