Description

Technical Field

[0001] The invention relates to the technical field of mixers, in particular to a concrete mixer which is convenient for feeding materials. Background Art

[0002] Concrete mixers are commonly used material processing devices at construction sites. Concrete mixers use a drive motor to drive the mixing shaft and the mixing blades installed on the mixing shaft to rotate, and use the mixing blades to mix.

[0003] In the existing concrete mixer, during use, the mixing device will cause the cement to have a heavier weight while the water has a lighter weight. In the case of slow delivery, the centrifugal force is small and will not have much impact. In the case of fast delivery, the centrifugal force is greater than the weight of the water but less than the weight of the cement itself, which will dehydrate the cement and make the delivered cement too hard and have poor fluidity, affecting the mixing effect. Therefore, we propose a concrete mixer that is easy to feed. Summary of the invention

[0004] A technical problem to be solved by the present application is: how to increase the fluidity and practicability of cement slurry when the fluidity is poor.

[0005] In order to solve the above technical problems, the embodiment of the present application provides a concrete mixer that is easy to feed, including a mixer body, a bracket is arranged below the mixer body, a roller is arranged below the bracket, and also includes: a pressing plate, which is arranged above the mixer body, and the pressing plate is used to press concrete downward to increase the flow rate of the concrete; a humidifying component, which is arranged on one side of the mixer body, and the humidifying component is used to add moisture to dry cement and mix it evenly; a lifting component, which is arranged inside the mixer body, and the lifting component is used to make the pressing plate reciprocate up and down.

[0006] In some embodiments, the humidification component includes a first water tank arranged on a bracket, a first water pump is arranged above the first water tank, a first water pipe is arranged above the first water pump, a fixed frame is arranged above the bracket, a fixed frame is arranged inside the fixed frame, a protective cover is arranged inside the fixed frame, a rotating motor is arranged inside the protective cover, and a stirring fan blade is arranged at one end of the rotating motor.

[0007] In some embodiments, the lifting assembly includes a driving motor arranged on one side of the agitator body, a rotating shaft is provided on one side of the driving motor, a cam is provided on the outer side of the rotating shaft, a connecting shaft is provided above the cam, and a moving part is provided on one side of the connecting shaft.

[0008] In some embodiments, the movable member includes a slide rail disposed on one side of the connecting shaft, a slide rod is disposed on one side of the slide rail, a connecting rod is disposed on one side of the slide rod, and one end of the connecting rod is fixedly connected to the pressure plate.

[0009] In some embodiments, a filter screen is provided at the interface between the agitator body and the first water pipe.

[0010] In some embodiments, the filter screen is made of 160-mesh stainless steel, with a wire diameter of 0.06 mm and a mesh size of 0.098 mm.

[0011] In some embodiments, a second water tank is provided on the other side of the bracket away from the first water tank, a second water pump is provided on the second water tank, a second water pipe is provided above the second water pump, and the first water tank and the second water tank are designed symmetrically relative to the center of the bracket.

[0012] The present invention has at least the following beneficial effects:

[0013] Different from the prior art, through the design of the humidifying component, the water missing during the stirring process of the stirring device will be re-humidified in the fixed cylinder and fully stirred, thus preventing the concrete output from being in blocks when output in the conveying pipe, thereby ensuring the stirring effect. Through the design of the lifting component, the pressure plate presses the concrete downward, thereby increasing the concrete conveying efficiency, thereby increasing the stirring efficiency.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figure 1-4 The present invention provides a technical solution: a concrete mixer that is convenient for feeding, including a mixer body 1, a bracket 2 is arranged below the mixer body 1, a roller 3 is arranged below the bracket 2, and also includes: a pressing plate 4, the pressing plate 4 is arranged above the mixer body 1, and the pressing plate 4 is used to press concrete downward to speed up the flow rate of the concrete; a humidifying component 5, the humidifying component 5 is arranged on one side of the mixer body 1, and the humidifying component 5 is used to add water to dry cement and stir it evenly, the humidifying component 5 includes a first water tank 51 arranged on the bracket 2, a first water pump 52 is arranged above the first water tank 51, and a first water delivery pipe is arranged above the first water pump 52 53. A fixing frame 54 is arranged above the bracket 2, a fixing frame 55 is arranged inside the fixing frame 54, a protective cover 56 is arranged inside the fixing frame 55, a rotating motor 57 is arranged inside the protective cover 56, and a stirring fan blade 58 is arranged at one end of the rotating motor 57. The pumping speed of the first water pump 52 can be controlled by the control switch on the concrete grouting device, and it can be ensured that the supplemented water will not be too much or too little through manual debugging. When the water content is too little, although the cement slurry is being stirred, the cement slurry is still in lumps due to insufficient water content. When the water content is too much, the fluidity of the cement slurry is too large after stirring, which will cause the cement to be sprayed out and unable to stick to the wall.

[0023] The lifting assembly 6 is arranged inside the agitator body 1. The lifting assembly 6 is used to make the pressing plate 4 reciprocate up and down. The lifting assembly 6 includes a driving motor 61 arranged on one side of the agitator body 1. A rotating shaft 62 is arranged on one side of the driving motor 61. A cam 63 is sleeved on the outer side of the rotating shaft 62. A connecting shaft 65 is arranged above the cam 63. A moving member 64 is arranged on one side of the connecting shaft 65. The moving member 64 includes a slide rail 641 arranged on one side of the connecting shaft 65 ... There is a sliding rod 642, and a connecting rod 643 is arranged on one side of the sliding rod 642. One end of the connecting rod 643 is fixedly connected to the pressure plate 4. The rotation of the driving motor 61 drives the rotating shaft 62 to rotate, thereby driving the cam 63 to rotate, thereby driving the rotation of the leveling connecting shaft 65 on the cam 63, thereby driving the rotation of the sliding rail 641, thereby driving the sliding rod 642 to move on the sliding rail 641, and the connecting rod 643 connected to the sliding rod 642 reciprocates and rises and falls on the support frame, thereby causing the pressure plate 4 to reciprocate up and down.

[0024] A filter screen 7 is provided at the interface between the agitator body 1 and the first water delivery pipe 53 to prevent cement from backwashing the water, thereby ensuring smooth water delivery.
