Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, in particular to a concrete raw material classification conveyor. Background Technique

[0002] Concrete is an artificial building material formed by mixing, pouring and solidifying cement, sand, gravel and water. It is one of the most commonly used building materials at present. Concrete has a strong bearing capacity. Due to the large amount of sand and gravel in its composition, concrete can withstand greater pressure and tensile force when stressed, thus having relatively high compressive strength and tensile strength. This enables concrete to be used for constructing the structural parts of various buildings and is one of the important materials in civil construction.

[0003] For the existing Chinese utility model patent with the reference publication number of: CN220479436U, it discloses a concrete raw material classification conveyor. The setting of this kind of concrete raw material classification conveyor includes a raw material cylinder, a first screening mesh, a second screening mesh and a conveying mechanism. The first screening mesh and the second screening mesh are inclined. The conveying mechanism includes a first feeding hopper, a second feeding hopper, a conveying pipe, a dragon, a first discharging pipe, a second discharging pipe and a conveyor belt. The aggregate to be conveyed can be added to the raw material cylinder. After passing through the raw material cylinder, the aggregate falls on the first screening mesh and slides down along the first screening mesh and the second screening mesh, so as to realize the screening of the aggregate. The screened aggregate can enter the conveying pipe through the first feeding hopper and the second feeding hopper, and is discharged respectively from the first discharging pipe and the second discharging pipe driven by the dragon. The conveyor belt can convey the discharged aggregate. At the same time, the unscreened aggregate can fall onto the conveyor belt from the end of the second screening mesh. Different conveyor belts can classify and convey aggregates of different sizes to facilitate the use of materials during concrete production.

[0004] During the use of the existing concrete raw material classification conveyor, since the internal materials of concrete are complex during transmission, it is impossible to distinguish between concrete and sand and gravel during transmission, resulting in sand and gravel being mixed into the interior of the concrete, making the materials unable to be mixed and put into use, which needs to be improved. Therefore, those skilled in the art provide a concrete raw material classification conveyor to solve the problems raised in the above background technique. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Combined with the attached Figures 1-4 In this embodiment, a concrete raw material classification conveyor includes a conveyor belt 1. A concrete crushing and classification mechanism is installed on the upper left side of the conveyor belt 1, and a concrete classification and transmission mechanism is installed in the middle above the conveyor belt 1. The concrete classification and transmission mechanism includes: a partition plate 13 installed in the middle above the conveyor belt 1, a partition belt 11 is installed below the partition plate 13, and fine sieve belts 12 are installed on both sides of the partition belt 11. A swivel ring 14 is arranged inside the conveyor belt 1, and two groups of collection boxes 15 are symmetrically installed below the conveyor belt 1; the partition belt 11 is sleeved outside the conveyor belt 1, and the partition plate 13 is located at the midpoint of the conveyor belt 1, and the fine sieve belts 12 are symmetrically arranged left and right through the midpoint of the conveyor belt 1. The number of the collection boxes 15 is two groups, and the collection boxes 15 are located below the fine sieve belts 12; the support rods 4 are fixedly arranged on both sides below the conveyor belt 1 at the same time, and the number of the swivel rings 14 is several.

[0025] Specifically, a partition belt 11 is sleeved in the middle outside the conveyor belt 1, partition plates 13 are installed on the upper and lower sides of the partition belt 11, the partition plates 13 divide the conveyor belt 1 into two parts, and a fine sieve belt 12 is arranged on the surface of the conveyor belt 1. The density of the fine sieve belt 12 is inconsistent, and it is divided by the partition belt 11. When the conveyor belt 1 transports the concrete device above the raw material device hopper 3, the concrete is screened through the aperture size of the fine sieve belt 12, and the concrete device is placed inside the collection box 15 during the transportation process, so as to classify the concrete device.

[0026] The concrete crushing and classification mechanism includes: a raw material hopper 3 installed above the left side of the conveyor belt 1. On one side of the raw material hopper 3, a second motor 31 is fixedly installed, and on one side of the second motor 31, a fixed rod 32 is connected. And one end of the fixed rod 32 is connected to a rotating shaft 33. An external ring of the rotating shaft 33 is a crushing shaft 34. And at the bottom of the raw material hopper 3, a feed hopper 35 is installed. And at the bottom of the feed hopper 35, a sieve 36 is provided; the raw material hopper 3 is fixedly installed above the left side of the conveyor belt 1 through a support rod 4. And two groups of rotating shafts 33 are arranged inside the raw material hopper 3. And the crushing shafts 34 are two groups arranged staggeredly up and down. The left side of the sieve 36 has a greater density. And the crushing shafts 34 are located in the lower middle part of the raw material hopper 3. And the midpoint of the partition belt 11 coincides with the midpoint of the feed hopper 35.

[0027] Specifically, a raw material hopper 3 is installed above the left side of the conveyor belt 1. A rotating shaft 33 is arranged in the lower middle part of the raw material hopper 3. An external ring of the rotating shaft 33 is a crushing shaft 34. The crushing shafts 34 are arranged staggeredly up and down. When the concrete raw material is poured into the raw material hopper 3, the rotating shaft 33 drives the crushing shaft 34 to rotate through the second motor 31, so as to roll the concrete inside the raw material hopper 3 and make it finer. Then, the sieve 36 at the bottom of the feed hopper 35 screens the particle size of the concrete, and the qualified concrete is discharged from one side of the sieve 36.

[0028] A support rod 4 is installed below the raw material hopper 3. And a first motor 2 is installed at the left rear of the conveyor belt 1. A device box 5 is installed in front of the conveyor belt 1; a middle plate 51 is fixedly installed in the middle of the device box 5. And a base 52 is fixedly installed at the bottom of the device box 5. And a connecting rod 53 is connected to the rear of the device box 5; the device box 5 is installed in front of the conveyor belt 1 through the connecting rod 53. And the middle plate 51 and the partition belt 11 are on the same horizontal line.

[0029] Specifically, the device box 5 is installed in front of the conveyor belt 1 through the connecting rod 53. And a middle plate 51 is arranged inside the device box 5. The middle plate 51 divides the device box 5. When there is some concrete with larger particles on the conveyor belt 1 that cannot be installed inside the collection box 15, it can be collected through the device box 5, and then the concrete material inside the device box 5 can be further divided.

[0030] Working principle: First, the excavated concrete is poured into the interior of the raw material device hopper 3. A rotating shaft 33 is arranged inside the raw material device hopper 3, and a crushing shaft 34 is arranged outside the rotating shaft 33. The crushing shafts 34 are arranged in two groups up and down and are staggered from each other. When the concrete enters the interior of the raw material device hopper 3, the rotating shaft 33 rotates through the arrangement of the second motor 31, thereby driving the crushing shaft 34 to rotate. This can roll and separate the freshly excavated concrete, and at the same time, it can also crush the sand and gravel to a certain extent. After crushing, the overall size of the concrete is relatively small and can be discharged through the feeding hopper 35 and the sieve 36 below the raw material device hopper 3. The density of the sieve 36 is different in size on the left and right. The sieve 36 on the left can discharge the fine concrete, and then it reaches the upper left side of the conveyor belt 1. A partition belt 11 is sleeved in the middle of the conveyor belt 1, and partition plates 13 are arranged above and below the partition belt 11 to divide the fine sieve belt 12 on the surface of the conveyor belt 1. The concrete dropped by the sieve 36 on the left is placed above the left side of the fine sieve belt 12. When the conveyor belt 1 is transporting, the fine sieve belt 12 can continuously discharge the concrete into the interior of the collection box 15 on the left for the concrete classification device. Then, according to the relatively large density of the sieve 36 on the right, the concrete with larger particle size can be discharged. The discharged concrete automatically falls to the right side of the fine sieve belt 12, and the fine sieve belt 12 discharges it into the interior of the collection box 15 on the right during the transmission process for the concrete classification device. Finally, if there is some residual concrete above the conveyor belt 1, through the arrangement of the conveyor belt 1 transmission, it can be placed in the device box 5 in front of the conveyor belt 1. After the device box 5 is filled, it can be poured into the interior of the raw material device hopper 3 or enter other processes to subdivide or process the raw materials. In this way, the entire use process of the concrete raw material classification conveyor is completed.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
