Concrete conveying device

Abstract

The utility model provides a concrete conveying device. Due to the fact that the screw pitch of the first auger blade is larger than that of the second auger blade, the gap of the spiral blades of the first auger blade is larger than that of the spiral blades of the second auger blade. In the process that materials are conveyed to the direction of the discharging port by the first auger blade and the second auger blade, the materials are compressed through the blade gaps of the second auger blade, and the materials are scattered in the forward conveying process through the blade gaps of the first auger blade. In other words, in the process that the first auger blade and the second auger blade convey the materials forwards, the first auger blade and the second auger blade enable the materials to be continuously compressed and scattered, so that the materials can be stirred and mixed while being conveyed, and the stirring and mixing efficiency of concrete is improved. Therefore, the first auger blade and the second auger blade are matched with each other, so that the concrete can be stirred and conveyed at the same time.

Description

Technical Field

[0001] This utility model relates to the technical field of concrete conveying devices, and in particular to a concrete conveying device. Background Technology

[0002] Concrete pouring, a crucial part of civil engineering, involves precisely pouring carefully mixed and balanced concrete into molds, and then using methods such as vibration to plasticize and compact it, ultimately forming sturdy building components. Therefore, concrete conveying and mixing equipment are indispensable.

[0003] Existing concrete mixing and conveying systems are mostly limited to a single function: the mixing unit is specifically used to mix raw materials into concrete, while the conveying unit is responsible for transporting the mixed concrete to a designated location. Specifically, when concrete production is required, operators must first start the mixing unit, adding cement, sand, gravel, water, and other raw materials in the correct proportions and mixing them thoroughly. Once the concrete is prepared, the conveying unit must be started separately to transfer the mixed concrete from the mixing area to the construction or storage location.

[0004] This transition from mixing to conveying not only adds operational steps, making the entire production process more cumbersome, but also often requires additional manpower to coordinate the start-up, shutdown, and intermediate connections of the two machines, resulting in unnecessary waste of human resources. Furthermore, frequent equipment switching can also affect production efficiency, as each switch requires preparation time and adjustments. This is undoubtedly a bottleneck problem that urgently needs to be solved for the modern concrete processing industry, which strives for efficient and continuous production. Utility Model Content

[0032] Figure 1 is a schematic structural view of a concrete conveying device, as Figure 1 indicated, and with reference to Figures 2 to 5 The present embodiment provides a concrete conveying device, which comprises a mounting frame 100, a conveying pipe 200 and an auger assembly 300. The conveying pipe 200 is horizontally arranged on the mounting frame 100. The conveying pipe 200 is provided with a plurality of feeding ports 210 at one end and a discharging port 220 at the other end.

[0033] The auger assembly 300 comprises a plurality of first auger blades 310 and a plurality of second auger blades 320. The first auger blades 310 and the second auger blades 320 are both rotationally arranged on the conveying pipe 200. The first auger blades 310 and the second auger blades 320 are arranged in sequence. The front end of the first auger blade 310 is connected with the rear end of one second auger blade 320, and the rear end of the first auger blade 310 is connected with the front end of another second auger blade 320. The pitch of the first auger blade 310 is greater than the pitch of the second auger blade 320.

[0034] Specifically, the first auger blades 310 and the second auger blades 320 are arranged alternately, and the first auger blades 310 and the second auger blades 320 have the same rotation direction. The first auger blades 310 and the second auger blades 320 are smoothly connected, so as to convey the material in the direction of the discharging port 220 when the first auger blades 310 and the second auger blades 320 rotate. Further, since the pitch of the first auger blade 310 is greater than the pitch of the second auger blade 320, the gap of the helical blade of the first auger blade 310 is greater than the gap of the helical blade of the second auger blade 320.

[0035] Further, in the process that the material is conveyed by the first auger blade 310 and the second auger blade 320 to the discharging port 220, the blade gap of the second auger blade 320 compresses the material, and the blade gap of the first auger blade 310 causes the material to be scattered in the process of being conveyed forward. That is, in the process of conveying the material forward, the first auger blade 310 and the second auger blade 320 cause the material to be compressed and scattered constantly, so that the material can be conveyed and mixed at the same time, and the mixing efficiency of the concrete is improved.

[0036] Further, the auger assembly 300 further comprises a first motor 340, the first motor 340 is installed on the mounting frame 100, the first motor 340 is connected with the first auger blade 310 or the second auger blade 320, and is used for driving the first auger blade 310 and the second auger blade 320 to rotate. Further, each feeding port 210 is used for guiding a kind of concrete raw material into the conveying pipe 200.

[0037] In some embodiments of the utility model, as shown in Figure 4 and Figure 5 The auger assembly 300 further comprises a plurality of stirring plates 330, and the stirring plates 330 are fixedly arranged on the first auger blade 310. The plurality of stirring plates 330 are arranged at intervals along the spiral direction of the first auger blade 310, and the stirring plates 330 are parallel to the axis of the conveying pipe 200.

[0038] Specifically, since the blade gap of the first auger blade 310 is large, the material conveyed by the first auger blade 310 will be fluffy compared with the material conveyed by the second auger blade 320. In the process of continuously rotating the first auger blade 310, the stirring plates 330 can further mix the material, so that the material can be mixed more fully.

[0039] In some embodiments of the utility model, as shown in Figure 4 One end of the discharging port 220 of the conveying pipe 200 of one second auger blade 320, so that the material is guided into the discharging port 220 through the second auger blade 320. Specifically, since the pitch of the second auger blade 320 is smaller than the pitch of the first auger blade 310, when the material is discharged from the discharging port 220 through the second auger blade 320, the second auger blade 320 can extrude and exhaust the material to avoid a large number of bubbles existing in the material, so as to improve the quality of the concrete.

[0040] In some embodiments of the utility model, as shown in Figure 4As shown, one first auger blade 310 is arranged at one end of the feeding port 210 of the conveying pipe 200, so that the material is first introduced into the conveying pipe 200 through the first auger blade 310. Specifically, since the first auger blade 310 has a large pitch, the first auger blade 310 has high efficiency in conveying the material. The arrangement of the first auger blade 310 connected with the feeding port 210 can increase the efficiency of feeding the material into the conveying pipe 200, thereby improving the stirring and conveying efficiency of the material.

[0041] In some embodiments of the present application, as shown in Figure 1 and Figure 4 As shown, the front end of the conveying pipe 200 extends forwardly with a necked pipe 230, the discharge port 220 is arranged at the front end of the necked pipe 230, and the opening of the discharge port 220 faces downward. The switch mechanism 221 for controlling the opening and closing of the discharge port 220 is arranged at the discharge port 220. Specifically, the arrangement of the necked pipe 230 can further extrude the material discharged outwardly.

[0042] In some embodiments of the present application, as shown in Figure 5 As shown, the first auger blade 310 and the second auger blade 320 are centerless blades. Specifically, the arrangement of the first auger blade 310 and the second auger blade 320 as centerless blades can expand the stirring space of the material during the conveying process, thereby further improving the stirring efficiency of the material.

The auger conveying blade 420 is rotatably arranged on the feeding pipe 410. Each kind of material is conveyed into the conveying pipe 200 through one feeding assembly 400. Further, the pitches of the auger conveying blades 420 of each feeding assembly 400 are different, so that the conveying efficiency of the material is different, so that the auger conveying blades 420 with different pitches convey different materials.

[0044] In the present embodiment, as shown in Figure 4 As shown, the feeding assembly 400 further comprises a second motor 440, the second motor 440 is arranged on the mounting frame 100 and connected with the auger conveying blade 420, so as to drive the auger conveying blade 420 to rotate.
