Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, and more specifically, to a disc concrete mixer delivery pump. Background Technology

[0002] The disc concrete mixer delivery pump is a concrete on-site mixing unit that integrates feeding, mixing, filtering and pumping. It is especially useful in special construction sites such as mountainous areas where there is a lack of commercial concrete plants and concrete mixers need to be transported on-site. Therefore, the disc concrete mixer delivery pump has emerged.

[0003] Existing disc concrete mixer pumps use a mixing mechanism inside a disc mixing drum. A continuously rotating mixing frame mixes concrete raw materials and water to form concrete, which then flows into the pump and is pumped to the construction site. However, the existing disc concrete mixers have a simple mixing frame structure and low mixing efficiency, which affects the construction effect and reduces the quality of concrete construction. Therefore, it is necessary to develop a disc concrete mixer pump to overcome the shortcomings of the existing technology. Summary of the Invention

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, this utility model provides a disc concrete mixer conveying pump, including a main unit 1, a mixing tank 2 fixedly installed on the top of the main unit 1, a plurality of evenly distributed mixing components 3 arranged inside the mixing tank 2, an encapsulation transmission component 4 arranged on the top of the mixing components 3, and the lower end of the encapsulation transmission component 4 extending to the bottom of the mixing tank 2 and connected to the drive mechanism inside the main unit 1.

[0023] The encapsulated transmission assembly 4 includes a transmission cover 41 movably installed inside the mixing tank 2. A drive gear 44 is fixedly connected to the bottom of the transmission cover 41 and is fixedly connected to the mixing tank 2. Several driven gears 45 are evenly distributed and meshed on the outer side of the drive gear 44. The driven gears 45 are rotatably connected to the bottom of the transmission cover 41. Each driven gear 45 corresponds to a mixing assembly 3. The upper end of the mixing assembly 3 is fixedly connected to the bottom of the driven gear 45, and the lower end of the mixing assembly 3 is movably connected to the bottom of the mixing tank 2. Due to the driven gears 45, in cooperation with the drive gear 44, the transmission cover 41 can drive several mixing assemblies 3 to revolve around the protective sleeve 23. Simultaneously, the cooperation of the drive gear 44 and the driven gears 45 causes the mixing assembly 3 to rotate, effectively improving the stirring efficiency and thus enhancing the mixing effect and conveying efficiency.

[0024] The mixing tank 2 includes a mixing tank body 21 fixedly installed on the top of the main unit 1. The top of the mixing tank body 21 is integrally formed with a receiving hopper 22. The inner diameter of the upper end of the receiving hopper 22 is larger than the inner diameter of its lower end and the inner diameter of the mixing tank body 21. A protective sleeve 23 is fixedly connected to the middle of the inner cavity of the mixing tank body 21. The drive gear 44 is fixedly sleeved on the upper end of the outer surface of the protective sleeve 23.

[0025] The mixing assembly 3 includes two mixing frames 31 located below the transmission cover 41. The two mixing frames 31 are located at the upper and lower ends of the inner cavity of the mixing tank body 21, respectively. A number of evenly distributed positioning shafts 33 are fixedly connected between the two mixing frames 31. Positioning sleeves 32 are movably sleeved on the outside of the positioning shafts 33, and positioning shafts 33 are fixedly connected to the outer surface of the positioning sleeves 32. Due to the setting of the transmission cover 41, it can protect the driven gear 45 and the driving gear 44, and will not affect the falling of the stone.

[0026] The bottom of the inner cavity of the mixing tank body 21 is connected to a limiting support ring 35 via a bearing. The distance between the limiting support ring 35 and the inner wall of the mixing tank body 21 and the distance between the limiting support ring 35 and the protective sleeve 23 are the same. The length of the mixing frame 31 is adapted to the distance between the inner wall of the mixing tank body 21 and the outer surface of the protective sleeve 23.

[0027] Among them, several stirring racks 31 located at the bottom are arranged above the limiting support ring 35. The lower end of a positioning shaft 33 in the middle of the stirring rack 31 passes through the stirring rack 31 and is rotatably sleeved inside the limiting support ring 35. Several stirring racks 31 located at the top are arranged below the driven gear 45. The upper end of a positioning shaft 33 in the middle of the stirring rack 31 is fixedly connected to the bottom of the driven gear 45. Due to the setting of the limiting support ring 35, with the cooperation of several positioning shafts 33 in the middle, it can provide stable support for the lower end of several stirring components 3, thereby ensuring that when the encapsulated transmission component 4 drives the upper end of several stirring components 3 to rotate, it can maintain a stable stirring effect while overcoming the resistance of the mixture in the mixing tank body 21.

[0028] The protective sleeve 23 houses a drive shaft 42. The top of the drive shaft 42 has a fastening groove 46, which extends to the top of the protective sleeve 23 and abuts against the bottom of the drive cover 41. The lower end of the drive shaft 42 passes through the protective sleeve 23 and the mixing tank body 21 and extends into the interior of the main unit 1, where it is fixedly connected to the output end of the drive mechanism. A fastening bolt 43 is movably fitted in the middle of the drive cover 41. The lower end of the fastening bolt 43 passes through the drive cover 41 and is threaded into the inside of the fastening groove 46. The upper end of the fastening bolt 43 is pressed onto the top of the drive cover 41. Due to the fastening groove 46, with the cooperation of the fastening bolt 43, the drive cover 41 can be fixedly installed on the top of the drive shaft 42, which enables it to drive several mixing components 3 to rotate, thereby achieving the effect of transmission and mixing.

[0029] The main unit 1 is equipped with a feeding component 5 on one side. The feeding component 5 is connected to the interior of the mixing tank body 21 through a conveying mechanism. The other end of the main unit 1 is equipped with a filter receiving box 6. The bottom of one side of the mixing tank 2 is located directly above the filter receiving box 6 and has a discharge port. The bottom of the filter receiving box 6 is connected to a pumping mechanism 7. A pump is installed between the pumping mechanism 7 and the filter receiving box 6.

[0030] Working principle and usage process of this utility model:

[0031] Place the transmission cover 41 inside the mixing tank body 21, and press it onto the top of the transmission shaft 42 with the cooperation of the fastening bolt 43 and the fastening groove 46; then turn on the equipment and pour the powder into the feeding assembly 5, which can then enter the mixing tank body 21 with the cooperation of the conveying mechanism, while the stone falls into the mixing tank body 21 from between the transmission cover 41 and the inner wall of the mixing tank body 21.

[0032] Once the drive mechanism is running, it can drive several limiting support rings 35 and the bottom stirring components 3 to rotate around the protective sleeve 23 through the transmission shaft 42 and the transmission cover 41. With the cooperation of the drive gear 44, the driven gear 45 causes the stirring components 3 to rotate, thereby stirring the mixture between the mixing tank body 21 and the protective sleeve 23 through the stirring frame 31, the positioning sleeve 32 and the external stirring rod 34. The mixed slurry that has been stirred falls into the filter receiving box 6 from the discharge port at the bottom of the mixing tank body 21, and is then transported to the construction area by the pump and the pumping mechanism 7.
