Description
Technical Field
[0001] This utility model relates to the technical field of unloading devices, and in particular to an unloading device for commercial concrete mixing plants. Background Technology
[0002] With the rapid development of the construction industry, concrete, as an important building material, is widely used in various construction projects. Commercial concrete mixing plants, as the core link in concrete production and supply, are responsible for producing and supplying concrete that meets quality standards. A commercial concrete mixing plant typically consists of multiple mixers, conveyor belts, and unloading devices. Among these, the unloading device is one of the most important pieces of equipment, directly affecting the efficiency of concrete transportation and unloading, as well as the construction progress.
[0003] In existing commercial concrete mixing plants, after the concrete is mixed, it needs to be transported by concrete mixer trucks. The existing concrete mixer trucks drive directly under the mixing drum and unload the concrete directly into the concrete mixer trucks. During the unloading process, the concrete is easy to splash onto the outside of the concrete mixer truck, which can easily cause concrete waste, ground pollution, and concrete mixer truck pollution.
[0004] The existing patent (publication number: CN219132779U) discloses a discharge device for a commercial concrete mixing plant, belonging to the technical field of discharge device technology. This discharge device includes a receiving hopper. It allows an extension pipe to extend into the inlet of the concrete mixer truck, enabling the concrete to be confined and limited through the pipe throughout the discharge process, reducing the possibility of concrete splashing onto the outside of the concrete mixer truck and the ground. It can also adapt to concrete mixer trucks of different heights for discharge. When the electromagnetic vibrator is started, the entire discharge pipe and extension pipe will vibrate synchronously, effectively clearing any blockages in the discharge pipe and extension pipe. The vibration of the discharge pipe and extension pipe impacts a striking ball, and the reaction force of the striking ball causes the pipe walls of the discharge pipe and extension pipe to vibrate. The vibrating pipe walls shake off residual concrete, reducing concrete waste.
[0005] Existing patents offer solutions to the above problems, but they cannot clean the receiving hopper, nor can they control the discharge speed of concrete inside the receiving hopper.
[0006] Therefore, a material unloading device for commercial concrete mixing plants is proposed. Utility Model Content
[0007] The purpose of this utility model is to provide a discharge device for commercial concrete mixing plants, which can solve the problems of existing discharge devices for commercial concrete mixing plants that cannot clean the receiving hopper and cannot control the discharge speed of concrete inside the receiving hopper.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a discharge device for a commercial concrete mixing plant, comprising a receiving hopper, two electric push rods being provided on the side wall of the receiving hopper, the output ends of the two electric push rods being fixedly connected to a chassis, a discharge mechanism being provided on the side wall of the chassis, and a splash-proof mechanism being provided on the side wall of the chassis.
[0009] The unloading mechanism includes a mounting box located at the bottom of the chassis. A servo motor is installed inside the mounting box. A rotating shaft is fixedly connected to the output end of the servo motor. The rotating shaft is connected to the chassis bearing. A spiral blade is installed at the top of the rotating shaft. The spiral blade is movably connected to the receiving hopper.
[0010] Preferably, the splash-proof mechanism includes two connecting strips disposed on the side wall of the chassis, and splash-proof covers are disposed on the side walls of the two connecting strips, the diameter of the splash-proof covers being larger than the diameter of the bottom of the receiving hopper.
[0011] Preferably, a cleaning head is provided at the top of the rotating shaft. The cleaning head is Y-shaped, and the sidewall of the cleaning head is adapted to the top of the receiving hopper.
[0012] Preferably, a mounting base is fixedly connected to the side wall of the receiving hopper, and a vibration motor is provided on the top of the mounting base.
[0013] Preferably, the chassis is umbrella-shaped, and the diameter of the chassis is larger than the diameter of the bottom of the receiving hopper.
[0014] Preferably, a protective ring is provided at the bottom of the chassis, and the protective ring is inclined.
[0015] Preferably, the side wall of the installation box is provided with multiple ventilation slots, and the interior of the installation box is provided with a filter cover, which is a mesh structure.
[0016] Preferably, a plurality of reinforcing ribs are provided between the mounting base and the receiving hopper, and the plurality of reinforcing ribs are distributed at equal intervals.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This application incorporates a discharge mechanism. Through this mechanism, the chassis position is adjusted by an electric push rod, and a servo motor drives the spiral blade to rotate and push concrete, achieving a fast and efficient discharge process.

[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 Figures 1 to 5This utility model provides a technical solution:
[0030] A discharge device for a commercial concrete mixing plant includes a receiving hopper 1, two electric push rods 2 are installed on the side wall of the receiving hopper 1, the output ends of the two electric push rods 2 are fixedly connected to a chassis 3, a discharge mechanism 4 is installed on the side wall of the chassis 3, and a splash-proof mechanism 5 is installed on the side wall of the chassis 3.
[0031] The unloading mechanism 4 includes a mounting box 41 located at the bottom of the chassis 3. A servo motor 42 is installed inside the mounting box 41. A rotating shaft 43 is fixedly connected to the output end of the servo motor 42. The rotating shaft 43 is connected to the bearing of the chassis 3. A spiral blade 44 is installed on the top of the rotating shaft 43. The spiral blade 44 is movably connected to the receiving hopper 1.
[0032] Specifically, such as Figure 3 As shown, a cleaning head 6 is provided on the top of the rotating shaft 43. The cleaning head 6 is Y-shaped and its sidewall is adapted to the top of the receiving hopper 1.
[0033] Specifically, such as Figure 1 As shown, a mounting base 7 is fixedly connected to the side wall of the receiving hopper 1, and a vibration motor 8 is provided on the top of the mounting base 7.
[0034] Specifically, such as Figure 3 As shown, the chassis 3 is umbrella-shaped, and the diameter of the chassis 3 is larger than the diameter of the bottom of the receiving hopper 1.
[0035] Specifically, such as Figure 3 As shown, a protective ring 9 is provided at the bottom of the chassis 3, and the protective ring 9 is inclined.
[0036] Specifically, such as Figure 5 As shown, multiple ventilation slots 10 are provided on the side wall of the mounting box 41, and a filter cover 11 is provided inside the mounting box 41. The filter cover 11 is mesh-like.
[0037] Specifically, such as Figure 1 As shown, multiple reinforcing ribs 12 are provided between the mounting base 7 and the receiving hopper 1, and the multiple reinforcing ribs 12 are distributed at equal intervals.
[0038] In a commercial concrete mixing plant, when unloading is required, firstly, the two electric push rods 2 on the side wall of the receiving hopper 1 are activated. The output ends of the electric push rods 2 extend, pushing the chassis 3 downwards, creating a certain gap between the chassis 3 and the bottom of the receiving hopper 1. Then, the servo motor 42 inside the mounting box 41 is activated, driving the rotating shaft 43 to rotate. The spiral blade 44 at the top of the rotating shaft 43 rotates accordingly. The spiral blade 44 is movably connected to the receiving hopper 1. During rotation, the spiral blade 44 pushes the concrete in the receiving hopper 1 downwards, realizing the concrete unloading operation. While the spiral blade 44 rotates, it effectively cleans the material adhering to the inner wall of the receiving hopper 1. At the same time, the Y-shaped cleaning head 6 at the top of the rotating shaft 43 also rotates with the rotating shaft 43. The side wall of the cleaning head 6 is adapted to the top of the receiving hopper 1, and during rotation, it can clean the concrete remaining on the top of the receiving hopper 1, preventing concrete from being discharged. Accumulation affects subsequent use. The vibration motor 8 generates vibration, which is transmitted to the receiving hopper 1. This vibration can break down the internal bonding force of the concrete, making the concrete looser and allowing the spiral blade 44 to push the concrete more effectively. Multiple ventilation slots 10 on the side wall of the mounting box 41 ensure air circulation inside the mounting box 41, which is beneficial for the heat dissipation of the servo motor 42. The internal mesh filter cover 11 can prevent dust and other impurities from entering the mounting box 41 and protect the servo motor 42 to work normally. Thus, through the setting of the unloading mechanism 4, the position of the chassis 3 is adjusted by the electric push rod 2, and the servo motor 42 drives the spiral blade 44 to rotate and push the concrete, realizing a fast and efficient unloading process. By controlling the speed of the servo motor 42, the unloading speed of the concrete material can be controlled, and the receiving hopper 1 can be cleaned during the unloading process to avoid concrete material adhering to the receiving hopper 1 and being difficult to clean.
[0039] Specifically, such as Figure 4 As shown, the splash-proof mechanism 5 includes two connecting strips 51 disposed on the side wall of the chassis 3, and splash-proof covers 52 are disposed on the side walls of the two connecting strips 51. The diameter of the splash-proof covers 52 is larger than the diameter of the bottom of the receiving hopper 1.
[0040] During the unloading process, the two connecting strips 51 on the side wall of the chassis 3, which are fixed to the splash guards, begin to play their role. Since the diameter of the splash guard 52 is larger than the diameter of the bottom of the receiving hopper 1, when the concrete is discharged from the bottom of the receiving hopper 1, the splash guard 52 can effectively block the concrete from splashing out, preventing the concrete from splashing onto the surrounding environment or equipment, and keeping the work area clean.
[0041] By adopting the above technical solution, the problems of existing unloading devices for commercial concrete mixing plants being unable to clean the receiving hopper 1 and being unable to control the concrete discharge speed inside the receiving hopper 1 have been solved.
[0042] Working Principle: When this application is in use, when unloading is required, firstly, the two electric push rods 2 on the side wall of the receiving hopper 1 are activated. The output end of the electric push rod 2 extends and pushes the chassis 3 downward, so that the chassis 3 and the bottom of the receiving hopper 1 form a certain distance. Then, the servo motor 42 in the mounting box 41 is activated. The servo motor 42 drives the rotating shaft 43 to rotate, and the spiral blade 44 at the top of the rotating shaft 43 rotates accordingly. The spiral blade 44 is movably connected to the receiving hopper 1. During the rotation, the spiral blade 44 pushes the concrete in the receiving hopper 1 downward, realizing the unloading operation of the concrete. While the spiral blade 44 rotates, it effectively cleans the material adhering to the inner wall of the receiving hopper 1. At the same time, the Y-shaped cleaning head 6 at the top of the rotating shaft 43 also rotates with the rotating shaft 43. The side wall of the cleaning head 6 is adapted to the top of the receiving hopper 1. During the rotation, it can clean the concrete remaining on the top of the receiving hopper 1, preventing concrete accumulation from affecting subsequent use. The anti-splash cover 52 can effectively block concrete from splashing out, preventing concrete from splashing onto the surrounding environment or equipment.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
