DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0023] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0025] Embodiment 1:

[0026] See also Figure 1 , provides a multifunctional cement mixing and conveying machine for road and bridge construction, including a main supporting frame 11, a conveying pipeline 14 erected on the main supporting frame 11, and a mixing drum 16 installed on the conveying pipeline 14; an output head 15 is provided at the terminal of the conveying pipeline 14; a reinforcing bracket 12 for support is also erected on the conveying pipeline 14; a pusher 13 is provided at the driving end of the conveying pipeline 14; a mixing bucket 17 is provided at the bottom end of the mixing drum 16, an output bin 18 and a material discharge pipe 19 arranged at the bottom of the output bin 18 are installed on the mixing bucket 17, and the material discharge pipe 19 is connected to the mixing bucket 17.

[0027] The mixing bucket 17 is provided with a mixing shaft 21 and is installed on a first mixing disk 22 and a second mixing disk 23 , wherein the first mixing disk 22 and the second mixing disk 23 are arranged symmetrically; an output frame 24 is provided at the shaft end of the mixing shaft 21 .

[0028] This embodiment is used for the operation and processing of a functional cement mixing and conveying integrated machine, and is committed to optimizing the design of the mixing cylinder 16 to enhance its ability to mix and preliminarily crush materials. The main support frame 11 serves as the support foundation for the entire equipment, ensuring the stability and reliability of the equipment.

[0029] The conveying pipeline 14 is horizontally or inclinedly installed on the main support frame 11. The mixing cylinder 16 is installed on the upper part of the conveying pipeline 14 and is used to mix raw materials such as cement, sand, and water. A stirring device is provided inside the mixing cylinder 16 and is driven by an external motor to achieve rotational mixing. The strengthening bracket 12 is installed at an appropriate position of the conveying pipeline 14 to enhance the support strength of the conveying pipeline and prevent deformation or sag caused by the weight of the materials. The pusher 13 is installed at the driving end of the conveying pipeline 14 and usually adopts a hydraulic or pneumatic driving method to provide power for the movement of materials in the conveying pipeline. The mixing hopper 17 is located below the mixing cylinder 16 and is used to collect the mixed materials. The mixing hopper 17 is designed with a structure that is easy to clean and discharge materials, facilitating maintenance and operation. The output bin 18 is installed on the mixing hopper 17 and is connected to the blanking pipeline 19. An adjustment mechanism is provided inside the output bin 18 to control the blanking speed and quantity of the materials. The terminal output head 15 connecting the output bin 18 and the conveying pipeline 14 ensures that the mixed materials can be smoothly conveyed to the designated position.

[0030] This embodiment enables the mixing cylinder to have a preliminary material crushing function, capable of processing larger particle materials within a certain range, reducing the requirements for the particle size of raw materials, and improving the applicability and flexibility of the equipment. The materials are fully cut, broken, and stirred inside the mixing cylinder, effectively improving the mixing uniformity and reducing the problem of uneven mixing caused by different particle sizes of materials. The improvement of the mixing uniformity and the enhancement of the preliminary crushing ability enable the equipment to process more materials within the same time, thereby improving the overall working efficiency.

[0031] Embodiment Two:

[0032] Both the first mixing disk 22 and the second mixing disk 23 include a disk pier 31, a disk body 32 provided on the disk pier 31, and mixing teeth 33 installed on the disk body 32. The mixing teeth 33 on the upper and lower sides are arranged in a meshing manner, and a mixing gap 34 is formed between the meshing gaps of the mixing teeth 33. Inner grooves 35 are provided on the inner edges of the upper and lower disk piers 31, and a material suction area 36 is formed between the inner grooves 35 on the upper and lower sides. A guiding groove strip 37 is provided on the side edge of the disk body 32, and the guiding groove strip 37 is used to connect the material suction area 36 and the mixing gap 34.

[0033] This embodiment is mainly composed of the first mixing disk 22 and the second mixing disk 23, which cooperate with each other to achieve efficient cement mixing.

[0034] The disk pier 31, as the basic part of the mixing disk, is firmly installed on the mixing cylinder or the relevant support. The disk pier 31 is designed as a disk-shaped structure with a certain thickness to ensure the stability and durability of the mixing disk; the disk body 32 is installed on the disk pier 31, and the mixing teeth 33 are evenly distributed on the disk body 32. The mixing teeth 33 on the upper and lower sides are arranged in a meshing manner, that is, the tip of one mixing tooth corresponds to the groove of another mixing tooth. This design enables the mixing teeth to interleave with each other when the two disks rotate relative to each other, forming an effective mixing effect. The meshing gap between the mixing teeth 33 is the mixing gap 34, and the material is sheared, extruded, and agitated in these gaps, thereby achieving uniform mixing; inner grooves 35 are provided along the inner edges of the disk piers 31 on both the upper and lower sides. The depth and width of these grooves are carefully designed to form sufficient space to accommodate and guide the material. When the two disks rotate relative to each other, a material suction area 36 is formed between the inner grooves 35 on the upper and lower sides. Under the guiding action of the guiding groove strips 37, the material can smoothly enter the mixing gap 34 and further be sheared and agitated by the mixing teeth 33.

[0035] Embodiment Three:

[0036] The export rack 24 includes a locking sleeve 41 arranged on the mixing rotating shaft 21, an arc-shaped inner bent frame 42 installed on the periphery of the locking sleeve 41, and an output stirring claw 43 arranged on the arc-shaped inner bent frame 42. The export rack 24 is guided into the inner cavity of the pipe of the output bin 18. The mixing rotating shaft 21 starts to rotate driven by the motor, driving the locking sleeve 41, the arc-shaped inner bent frame 42, and the output stirring claw 43 to rotate together. After the material is fully mixed in the mixing area, it is sucked or pushed to the inlet of the export rack 24. Under the stirring and dispersing action of the output stirring claw 43, the material smoothly enters the inner cavity of the pipe of the output bin 18 along the guidance of the arc-shaped inner bent frame 42. The material further accumulates and stores in the output bin 18 until it reaches the set amount and is discharged to the construction site through the blanking pipeline 19.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to encompass all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
