Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete production technology, specifically to a concrete production material separation device. Background Technology
[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term concrete usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering.
[0003] During concrete feeding, materials are dumped into a discharge seat by a transport vehicle and discharged onto a conveyor belt for transport to the mixing plant for feeding and mixing. The discharge seat is usually equipped with isolation strips to isolate large-sized aggregates in the unloaded raw materials. However, the accumulation of large-sized aggregates after isolation is not cleaned up in a timely manner. At the same time, the materials are usually excavated from the storage pile and stored in the transport vehicle by an excavator, which makes it easy for weeds to be present in the raw materials. Therefore, we propose a concrete production material separation device to solve this technical defect. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a concrete production material separation device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete production material separation device, including a discharge seat, a feeding hopper, a pushing drive component, and a transverse drive component. The feeding hopper contains multiple burr rollers arranged in a planar array. The discharge seat contains multiple triangular partitions arranged in a planar array. A discharge hole is provided on one side of the discharge seat facing the inclined surface of the triangular partitions. A switch plate is provided in the discharge hole. The pushing drive component connects the discharge seat and the switch plate. A slidable sealing plate is provided on one side of the discharge seat facing the inclined surface of the triangular partitions. The transverse drive component connects the discharge seat and the sealing plate. A pair of collecting discharge hoppers located below the sealing plate are provided outside the discharge seat.
[0006] Using the above technical solution, after the transported concrete raw materials are poured into the feeding hopper, the raw materials are processed by the burr roller, which drives the burr roller to roll and remove weeds from the raw materials. The processed raw materials pass through triangular partitions, and large particles of raw materials are screened by the gaps between the triangular partitions. The screened large particles of raw materials roll along the inclined surface of the triangular partitions to both sides of the discharge seat. When the screened large particles of raw materials are discharged, the transverse drive is activated to close the sealing plate, and at the same time, the push drive is moved to separate the switch plate from the discharge hole, so that the large particles of raw materials can be discharged into the collection hopper through the discharge hole for collection.
[0007] As a preferred embodiment of this utility model, the burr roller includes a rotating roller and multiple spring rods. The rotating roller rotates circumferentially between the inner walls of the hopper, and the spring rods are springs with a number of burrs evenly distributed on them.
[0008] Using the above technical solution, during unloading, the material comes into contact with the rotating roller, causing the roller to rotate. At the same time, the raw material comes into contact with the spring rod, causing the spring rod to deform and the weeds in the raw material to be caught on the burr, thus achieving the treatment of weeds in the raw material.
[0009] As a preferred embodiment of this utility model, the front and rear sides above the triangular partition are inclined surfaces, and the lengths of the discharge hole, the switch plate, and the sealing plate are equal to the length of the discharge seat cavity.
[0010] By adopting the above technical solution, the sealing effect of the switch board on the discharge hole is guaranteed, and the sealing plate closes to isolate and seal the discharge seat.
[0011] As a preferred embodiment of this utility model, the sealing plate is located above the triangular partition. When the sealing plate is in a movable closed state, the sealing plate and the discharge seat are not separated, and the combined sealing plate seals the opening of the discharge seat.
[0012] By adopting the above technical solution, gaps between the sealing plate and the inner wall of the discharge seat are avoided when the sealing plate is in the closed state.
[0013] As a preferred embodiment of this utility model, the bottom of the collecting and discharging hopper is open, and the collecting and discharging hopper is provided with equally spaced isolation strips.
[0014] The above technical solution facilitates the discharge of small particulate raw materials into the collection hopper through the gaps between the separator strips.
[0015] As a preferred embodiment of this invention, the gap width between the isolation strips is equal to the gap width between the triangular partitions.
[0016] By adopting the above technical solution, it is ensured that the dimensions of the material separated by the gap between the isolation strip and the triangular partition are consistent.
[0017] As a preferred technical solution of this utility model, the pushing drive component includes a loading plate and a hydraulic push rod. The loading plate is connected to the outside of the collection and discharge hopper, and the push rod of the hydraulic push rod is connected to the switch plate. The loading plate and the hydraulic push rod are assembled and connected.
[0018] Using the above technical solution, the hydraulic push rod pushes the switch plate to move, thereby opening and closing the switch plate.
[0019] As a preferred embodiment of this utility model, the transverse drive component includes a mounting base and an electric guide rail. The mounting base is connected to the outside of the discharge seat, and the guide rail slide of the electric guide rail is connected to the sealing plate. The mounting base and the electric guide rail are assembled and connected.
[0020] Using the above technical solution, the electric guide rail drives the sealing plate to move, realizing the combined closing and opening of the sealing plate.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] This concrete production material separation device uses a feeding hopper to easily transport concrete raw materials. After the raw materials are poured into the hopper, they pass through a burr roller, which drives the roller to roll and remove weeds. The processed raw materials then pass through triangular partitions. Larger particles are screened by the gaps between the triangular partitions, causing them to roll along the inclined surfaces of the partitions to both sides of the discharge seat. When the screened large particles are discharged, the horizontal drive component is activated, which closes the sealing plate and simultaneously pushes the drive component to separate the switch plate from the discharge hole. This allows the large particles to be discharged into the collection hopper for collection. This method avoids the problem of traditional isolation strips directly separating the raw materials, which is inconvenient for cleaning during unloading, while also removing weeds from the raw materials, thus improving the separation effect.

Detailed Implementation
[0028] 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.
[0029] Please see Figure 1 The concrete production material separation device in this embodiment includes a discharge seat 1, a feeding hopper 2, a pushing drive component 9, and a transverse drive component 11. The discharge seat 1 has an opening at the bottom. When installing the discharge seat 1, the feeding hopper 2 is installed directly above the conveyor belt by fastening screws, so that the raw materials discharged through the discharge seat 1 fall onto the conveyor belt and are transported to the mixing plant. The discharge seat 1 is equipped with a control box and a control panel on its exterior. The control box and control panel are existing technologies and are electrically connected to the electrical equipment of this application for system control of the equipment and operation control by the user. The discharge seat 1 is equipped with multiple burr rollers 3 arranged in a planar array. The burr rollers 3 include rotating rollers 31 and multiple spring rods 32. The rotating rollers 31 rotate circumferentially between the front and rear side walls of the inner cavity at the opening of the hopper 2. The spring rods 32 are springs, and several equidistant burrs are distributed on the spring rods 32.
[0030] It should be added that the spacing between the spring rods 32 on two adjacent rotating rollers 31 is between 0.5CM and 1CM, the spacing between the spring rods 32 on the same rotating roller 31 is between 1CM and 5CM, and the length of the spring rods 32 is between 1CM and 3CM.
[0031] When the raw materials on the transport vehicle are unloaded into the feeding hopper 2, the materials come into contact with the rotating roller 31 in the discharge seat 1. The impact of the materials drives the rotating roller 31 to rotate. At the same time, the raw materials contact the spring rod 32, causing the spring rod 32 to deform and create a gap for material to fall. At the same time, the weeds in the raw materials come into contact with the burrs on the spring rod 32 and are hung on the burrs, thus realizing the treatment of weeds in concrete raw materials.
[0032] Please see Figure 2-3Multiple triangular partitions 4 arranged in a planar array are installed and fixed between the front and rear side walls of the inner cavity of the discharge seat 1. A discharge hole 5 is provided on the side of the discharge seat 1 facing the inclined surface of the triangular partitions 4. A switch plate 6 is movably inserted and sealed in the discharge hole 5. A push drive component 9 connects the discharge seat 1 and the switch plate 6. A pair of collection discharge hoppers 7 located below the sealing plate 10 are installed and fixed on the outside of the discharge seat 1. The push drive component 9 includes a loading plate 91 and a hydraulic push rod 92. The loading plate 91 is connected and fixed to the outside of the collection discharge hopper 7 by fastening screws. The push rod of the hydraulic push rod 92 is connected and fixed to the switch plate 6. The loading plate 91 and the hydraulic push rod 92 are assembled and fixed by fastening screws. The side of the discharge seat 1 facing the inclined surface of the triangular partitions 4 can slide. A sealing plate 10 passes through the discharge seat 1. A transverse drive 11 connects the discharge seat 1 and the sealing plate 10. The transverse drive 11 includes a mounting base 111 and an electric guide rail 112. The mounting base 111 is fixed to the right side of the discharge seat 1. The guide rail slide of the electric guide rail 112 is fixed to the sealing plate 10. The mounting base 111 and the electric guide rail 112 are assembled and fixed by fastening screws. The front and rear sides above the triangular partition 4 are inclined surfaces. The length of the discharge hole 5, the switch plate 6 and the sealing plate 10 is equal to the length of the inner cavity of the discharge seat 1. The sealing plate 10 is located above the triangular partition 4. When the sealing plate 10 is in the moving closed state, the sealing plate 10 and the discharge seat 1 are not separated, and the combined sealing plate 10 seals the opening of the discharge seat 1.
[0033] In the above scheme, after the concrete raw materials are unloaded into the feeding hopper 2 and weeded, the processed raw materials fall onto the triangular partitions 4 inside the discharge seat 1. Raw materials smaller than the gap size between the triangular partitions 4 fall through the gap onto the conveyor belt below the discharge seat 1, while raw materials larger than the gap size roll down the inclined surface of the triangular partitions 4 to the side of the discharge seat cavity for storage (it should be noted that at this time, the switch plate 6 closes the discharge hole 5). When it is necessary to discharge large-sized raw materials that have been screened and stored, the electric guide rail 112 is first activated. The hydraulic push rod 92 moves the sealing plate 10 to close, sealing the discharge seat 1 and preventing the raw material from being discharged onto the triangular partition 4. Then, the hydraulic push rod 92 is activated to separate the switch plate 6 from the discharge hole 5, allowing the stored large particles of raw material to be discharged into the collection hopper 7 for storage. After cleaning, the hydraulic push rod 92 is activated to close the discharge hole 5, and the electric guide rail 112 is activated to move the sealing plate 10 to open, allowing the continued discharge and separation of large particles of raw material, which is then discharged onto the conveyor belt.
[0034] Please see Figure 4 The bottom of the collection hopper 7 is open, and the collection hopper 7 is provided with equally spaced isolation strips 8. The gap width between the isolation strips 8 is equal to the gap width between the triangular partitions 4.
[0035] Furthermore, after the screened raw materials are discharged into the collection hopper 7 through the discharge hole 5 for storage, a small amount of small particles of raw materials are discharged again through the gaps between the isolation strips 8 and fall onto the conveyor belt below for transportation to the mixing plant.
[0036] The working principle of the above embodiments is as follows:
[0037] The concrete raw materials are poured into the feeding hopper 2 for easy transport. After the raw materials fall, they are driven by the burr roller 3 to roll and remove weeds. The processed raw materials pass through the triangular partition 4. Large particles of raw materials are blocked and screened by the gaps between the triangular partitions 4. The screened large particles of raw materials roll along the inclined surface of the triangular partition 4 to both sides of the discharge seat 1. When the screened large particles of raw materials are discharged, the transverse drive component 11 is activated to close the sealing plate 10. At the same time, the push drive component 9 drives the switch plate 6 to separate from the discharge hole 5, so that the large particles of raw materials can be discharged into the collection discharge hopper 7 through the discharge hole 5 for collection.
[0038] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control functions, and the existing publicly available power connection technologies are not described in detail in the text.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
