Description

Technical Field

[0001] The utility model belongs to the technical field of geotechnical engineering, and particularly relates to a cement-soil mixing device. Background Art

[0002] A cement-soil mixing device is a mechanical device that improves the physical and chemical properties of the soil and increases its strength and stability by mixing cement slurry with the soil. By using a cement-soil mixing device, the foundation conditions can be effectively improved and the stability and safety of the building can be enhanced. With the continuous advancement of technology, the cement-soil mixing device will play a greater role in future foundation treatment and engineering construction.

[0003] In the existing cement-soil mixing device, workers pour raw materials such as cement, sand, and various dry powder mortars from the guide hopper into the crushing drum, and control the operation of the crushing module through a motor to crush the poured cement, sand, and various dry powder mortars and other raw materials, and then make the crushed raw materials fall into the mixing drum. Then, the motor controls the rotating shaft with a stirring paddle to rotate in the mixing drum to stir and mix these different raw materials so that they are stirred into a mixture of suitable consistency. However, in the actual mixing process, most of the raw materials poured into the crushing drum from the guide hopper meet the mixing standards in shape and size, and only some raw materials have a larger volume. When the raw materials are crushed by the crushing module, due to the presence of a large amount of raw materials that meet the standards, the crushing module has a long idling time during crushing, and many materials that do not need to be crushed are ineffectively crushed by the crushing module. These raw materials are crushed for a long time in the crushing drum before falling into the mixing drum for stirring, which makes it take a certain amount of time to mix the cement soil, affecting the efficiency of cement soil mixing. Utility Model Content

[0004] In view of this, the utility model addresses the deficiencies of the existing technology and provides a cement soil mixing device, which can screen the raw materials after pouring them in so that the raw materials that meet the standards fall into the mixing box, and then quickly and evenly crush the raw materials that do not meet the standards in the crushing box, avoiding ineffective crushing, reducing the time required for crushing, and ensuring the efficiency of cement soil mixing.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a cement soil mixing device, including a bracket, a support leg is provided on the lower surface of the bracket, a mixing box is provided on the top of the bracket, a crushing box is provided on the upper surface of the mixing box, a feed hopper is provided at the feed port opened on the upper surface of the crushing box, a discharge pipe is provided at the discharge port opened on the lower surface of the mixing box, an electromagnetic valve is connected in series inside the discharge pipe, a plurality of evenly distributed rotating shafts are provided for rotation inside the mixing box, the outer arc surfaces of the rotating shafts are fixedly sleeved with stirring paddles, and a crushing module for crushing raw materials is also provided on the crushing box; evenly distributed motors are provided on the right side of the mixing box, and the output shafts of the motors are fixed to adjacent rotating shafts through couplings; anti-slip pads are provided on the lower surfaces of the support legs.

[0006] As a further improvement of the present invention, the crushing module includes guide rails symmetrically arranged inside the crushing box, and sliding seats are slidingly arranged on the outer arc surfaces of the guide rails. A crushing trough is arranged between the two sliding seats, and a plurality of evenly distributed leakage ports are opened on the lower surface of the crushing trough. A symmetrically distributed U-shaped frame is arranged at the top inner top of the crushing box, and a symmetrically distributed mounting seat is arranged at the bottom end of the U-shaped frame.

Motor three is arranged inside the front mounting seat, and the output shafts of motor three are respectively fixed to the adjacent crushing rollers through couplings. The crushing box is also provided with an electronic control unit for driving the crushing trough to shake.

[0007] As a further improvement of the present invention, the electronic control unit includes a rotating rod rotatably arranged inside the crushing box, the outer arc surface of the rotating rod is fixedly sleeved with a crank, and the end of the crank away from the rotating rod is rotatably provided with a connecting rod, and the end of the connecting rod away from the crank is rotatably connected to the crushing trough. The crushing box is also provided with an electronic control component for driving the rotating rod to rotate; the electronic control component includes a second motor arranged at the rear side of the crushing box, and the output shaft of the second motor is fixed to the rotating rod by a coupling.

[0008] As a further improvement of the present invention, the electric control assembly includes a second motor arranged at the rear side of the crushing box, and the output shaft of the second motor is fixed to the rotating rod via a coupling.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] First, the output shaft of motor 2 drives the rotating rod connected to it to rotate, and then the rotating rod drives the crank to rotate forward and reverse in a cycle, causing the crushing trough to continuously swing back and forth left and right. Through the swing of the crushing trough, the raw materials falling into the crushing trough leak out from the leakage port and fall into the inside of the mixing box.

[0011] Secondly, the operation of motor three is regulated by the control box, so that the output shaft of motor three drives the crushing roller connected to it to rotate, so that the raw materials remaining in the crushing trough can quickly and evenly contact the crushing roller under the action of the shaking of the crushing trough, and the raw materials that do not meet the standards can be quickly and evenly crushed.

[0012] Thirdly, the output shaft of the motor 1 drives the rotating shaft connected thereto to rotate, and then the rotating shaft drives the stirring paddle connected thereto to rotate, thereby quickly and evenly stirring the raw materials in the mixing box.

[0013] Fourthly, the anti-slip pad on the lower surface of the foot can effectively increase the friction between the foot and the ground, preventing the position from moving easily during use. BRIEF DESCRIPTION OF THE DRAWINGS
