Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically a concrete conveying device. Background Technology

[0002] Concrete is one of the main civil engineering materials in modern times. It is an artificial stone material made by mixing cementitious materials, aggregates, and water in a certain proportion, followed by stirring, vibration, molding, and curing under certain conditions. Concrete is characterized by abundant raw materials, low price, and simple production process, which has led to its increasing use. Concrete also has advantages such as high compressive strength, good durability, and a wide range of strength grades. Its applications are very broad, not only in various civil engineering projects, but also in shipbuilding, machinery industry, marine development, geothermal engineering, and other fields.

[0003] Traditional concrete conveying systems employ intermittent delivery methods, such as waiting for the next concrete mixer truck after unloading. This discontinuous delivery process impacts construction progress, and the slow delivery speed fails to meet the rapid concrete delivery requirements of large-scale construction projects. Furthermore, the delivery process can generate significant dust and noise pollution, violating modern environmental protection requirements for construction. The inability to control the flow rate can also lead to uneven concrete distribution on the pouring surface, with some areas having too much or too little concrete. This affects the density and uniformity of the concrete structure, consequently impacting its overall strength and durability. Therefore, a concrete conveying system is needed to address these issues. Utility Model Content

[0004] To address the problems arising from the intermittent delivery methods of traditional concrete conveying devices, such as the need for concrete mixer trucks to wait for the next truck after unloading, which disrupts the construction progress, slows the delivery speed and fails to meet the rapid concrete delivery requirements of large-scale construction projects, and generates significant dust and noise pollution during delivery (incompatible with modern construction environmental protection requirements), and the inability to control the flow rate leads to uneven concrete distribution on the pouring surface, with some areas having too much or too little concrete, affecting the density and uniformity of the concrete structure and consequently its overall strength and durability, this invention aims to provide a concrete conveying device to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A concrete conveying device includes a main body, a screw conveying assembly fixedly connected to the top of the main body, and a discharge control assembly fixedly connected to the side of the screw conveying assembly.

[0007] The spiral conveyor assembly includes a sealed pipe, an insulation layer fixedly connected inside the sealed pipe, a spiral blade rod inside the sealed pipe, a support frame fixedly connected to the top of the sealed pipe, a motor mounted on the top of the support frame, a rotating wheel fixedly connected to the output end of the motor, a belt at the bottom of the rotating wheel, and a transmission wheel inside the belt.

[0008] The discharge control component includes a mounting box, inside which a telescopic rod is installed, and a baffle is fixedly connected to the output end of the telescopic rod.

[0009] As a preferred embodiment of this utility model, a feed hopper is fixedly connected to the top of the sealed pipe, and the transmission wheel is fixedly connected to the spiral blade rod.

[0010] As a preferred embodiment of this utility model, a mounting bracket is fixedly connected to the side of the sealed pipe, a bearing is installed inside the mounting bracket, and the spiral blade rod extends into the interior of the bearing.

[0011] As a preferred embodiment of this utility model, the bottom of the sealed pipe is fixedly connected to a discharge trough, the mounting box is disposed on the side of the discharge trough, and the baffle is disposed inside the discharge trough.

[0012] As a preferred embodiment of this utility model, a controller is fixedly connected to the side of the sealed pipe, and a start / stop button is provided on the side of the controller.

[0013] As a preferred embodiment of this utility model, a display screen is fixedly connected to the side of the controller, and physical buttons are provided on the side of the display screen, with a plurality of physical buttons provided.

[0014] As a preferred embodiment of this utility model, the main body includes a support frame, and two support frames are provided.

[0015] As a preferred embodiment of this utility model, the support frame is internally fixedly connected with reinforcing ribs, and several reinforcing ribs are provided.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, a transmission mechanism consisting of a rotating wheel, belt, and drive wheel is driven by an electric motor to transport concrete using a spiral blade rod. This spiral conveying method allows concrete to be transported within a completely sealed pipeline, preventing external contamination during transport and also preventing the spread of dust and noise, thus meeting environmental protection requirements. Simultaneously, the spiral blade rod can also mix the concrete, preventing segregation during transport and ensuring the uniformity and quality stability of the concrete. The sealed conveying system reduces leakage and waste during transport, improving material utilization.

[0018] 2. In this utility model, by utilizing the extension and retraction of the telescopic rod, the baffle can be changed to alter the obstruction gap in the discharge chute, thereby precisely controlling the concrete flow rate. This allows the concrete to be distributed more evenly on the pouring surface, avoiding excessive or insufficient concrete in local areas, thus ensuring the compactness and uniformity of the concrete structure. A stable flow rate can effectively reduce the risk of pipe blockage. When the flow rate is kept within a reasonable range, the concrete flows more smoothly in the pipe, and aggregates are less likely to accumulate, thereby reducing the possibility of blockage.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0026] A concrete conveying device includes a main body 1, a screw conveying assembly 2 fixedly connected to the top of the main body 1, and a discharge control assembly 3 fixedly connected to the side of the screw conveying assembly 2.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the screw conveyor assembly 2 includes a sealed pipe 201, an insulation layer 202 fixedly connected inside the sealed pipe 201, a screw blade rod 203 disposed inside the sealed pipe 201, a support frame 207 fixedly connected to the top of the sealed pipe 201, a motor 208 mounted on the top of the support frame 207, a rotating wheel 209 fixedly connected to the output end of the motor 208, a belt 210 disposed at the bottom of the rotating wheel 209, and a transmission wheel 211 disposed inside the belt 210. The discharge control assembly 3 includes a mounting box 301, a telescopic rod 302 installed inside the mounting box 301, and a baffle 303 fixedly connected to the output end of the telescopic rod 302. Driven by the motor 208, a transmission mechanism consisting of a rotating wheel 209, a belt 210, and a transmission wheel 211 is used to transport concrete via the helical blade rod 203. This helical conveying method allows concrete to be transported within a completely sealed pipeline, preventing external contamination during transport and also preventing the spread of dust and noise, thus meeting environmental protection requirements. While transporting concrete, the helical blade rod 203 can also mix the concrete, preventing segregation during transport and ensuring the uniformity and quality stability of the concrete. The sealed conveying reduces leakage and waste during transport, improving material utilization.

[0028] The sealing pipe 201 is fixedly connected to a feed hopper 204 at its top, and a drive wheel 211 is fixedly connected to a spiral blade rod 203. A mounting bracket 205 is fixedly connected to the side of the sealing pipe 201, and a bearing 206 is installed inside the mounting bracket 205. The spiral blade rod 203 extends into the bearing 206. A discharge trough 212 is fixedly connected to the bottom of the sealing pipe 201. A mounting box 301 is located on the side of the discharge trough 212, and a baffle 303 is located inside the discharge trough 212. The extension and retraction of the telescopic rod 302 can control the baffle 303 to change the obstruction gap in the discharge trough 212, thereby precisely controlling the concrete flow rate. This allows the concrete to be distributed more evenly on the pouring surface, avoiding excessive or insufficient concrete in local areas, thus ensuring the compactness and uniformity of the concrete structure. A stable flow rate can effectively reduce the risk of pipe blockage. When the flow rate is kept within a reasonable range, the concrete flows more smoothly in the pipe, and the aggregate is less likely to accumulate, thereby reducing the possibility of blockage.

[0029] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, a controller 213 is fixedly connected to the side of the sealed pipe 201. A start / stop button 215 is provided on the side of the controller 213. A display screen 214 is fixedly connected to the side of the controller 213. A number of physical buttons 216 are provided on the side of the display screen 214. The main body 1 includes a support frame 101. There are two support frames 101. A number of reinforcing ribs 102 are fixedly connected inside the support frame 101. The reinforcing ribs 102 can significantly improve the load-bearing capacity of the support frame 101 and enhance the overall stability of the equipment.

[0030] The working process of this utility model is as follows: When the concrete conveying device designed in this scheme is working, the concrete is poured from the feed hopper 204 so that it can enter the sealed pipe 201. The motor 208 drives the transmission mechanism composed of rotating wheel 209, belt 210 and transmission wheel 211, which enables the spiral blade rod 203 to convey the concrete. When the concrete needs to be discharged, the extension and retraction of the telescopic rod 302 can control the baffle 303 to change the obstruction gap in the discharge chute 212, thereby accurately controlling the amount of concrete flowing out.
