Description

Technical Field

[0001] The utility model relates to the technical field of cement mixer feeding, in particular to a cement mixer feeding device. Background Art

[0002] Cement is the most commonly used building structure material in the world today. Reinforced concrete made of cement, sand, gravel and steel bars is used in bridge projects, tunnel projects, coastal defense projects, underground projects and construction projects. It can bear weight, resist corrosion, resist frost, withstand high temperatures and resist earthquakes. Of course, without the hydration effect of water, cement will not be able to do anything. Therefore, cement needs to be mixed with water. The mixing speed of cement affects the efficiency of the construction site.

[0003] Publication No.: CN 218803137 U proposes a feeding auxiliary device for a cement mixer. In this case, conical thorns are arranged around the upper side of the inside of the mixing barrel; a baffle is arranged on the conveyor belt to prevent cement ash from flowing back. The cement ash is transported from bottom to top and enters the entrance of the cement mixer along the guide plate, and a dust cover is arranged above the guide plate to prevent excessive cement ash from being scattered and diffused and inhaled by the human body to cause health hazards. The entire operation process has less manual participation, saves labor, and improves personnel work efficiency. However, in actual application, it is impossible to adjust the height of the feeding place and its conveying inclination angle, so that the feeding device cannot be applied to cement mixers of different models, and its applicability is poor. Therefore, it is necessary to propose a feeding auxiliary device for a cement mixer to solve the above problems. Utility Model Content

[0006] By adopting the above technical solution, the driving member pushes the adjustment frame to slide left and right, so that the supporting roller slides left and right at the bottom of the feed conveyor belt. When moving to the left, the inclination angle of the feed conveyor belt and the conveying height of the right end can be changed to correspond to the feeding position of the cement mixer. After adjustment, the right end of the feed conveyor belt is supported by the telescopic component, so that the overall structure of the feed conveyor belt is more stable and the transportation of cement ash is safer and more stable.

[0018] By adopting the above technical solution, when cement ash enters the feed bin, the cement ash is rolled by the rolling element, so that the agglomerated cement ash is pressed into powder and filtered through the filter plate. Thereafter, the cement ash powder is transported through the feed conveyor belt, so that when it enters the cement mixer, the mixing efficiency is higher.

[0019] The utility model is further configured as follows: the rolling part includes a fixing bar fixedly connected to the feed bin, a main rotating rod is rotatably arranged on the fixing bar, four slave rotating rods are distributed on the bottom circumference of the outer side of the main rotating rod, and rolling rollers that fit the upper end surface of the filter plate are installed on the outer sides of the four slave rotating rods, and a rotating part for controlling the rotation of the main rotating rod is arranged on the side of the fixing bar away from the main rotating rod.

[0023] The utility model is further configured as follows: the rotating member comprises a motor installed at the lower end of the fixed bar, a synchronous wheel is installed on the output end of the motor and the main rotating rod, and a synchronous belt is used for transmission connection between the two synchronous wheels.

[0024] By adopting the above technical solution, the motor controls the rotation of the synchronous wheel, and drives another synchronous wheel to rotate through the action of the synchronous belt, thereby driving the main rotating rod to rotate and crush the cement ash.

[0025] The beneficial effects of the utility model are:

The screw rod can be rotated by holding the handle. When the lifting block is driven to move up and down, the side plate drives the bottom connecting plate to rise and fall, so that it contacts the ground, stably supporting the bottom of the right end of the feed conveyor belt, making the adjustment more stable, and being better suitable for the feeding needs of cement mixers of different models.

[0027] 2.
