Abstract
Description
Technical Field
[0001] This utility model relates to the field of building material conveying technology, specifically a material conveying device for building and municipal construction. Background Technology
[0002] Material transportation in building and municipal construction is a fundamental aspect of ensuring the smooth progress of projects, primarily involving the efficient flow of building materials such as sand, gravel, steel bars, and concrete from the supply end to the construction site. Its core significance lies in ensuring the timely and sufficient arrival of materials through the scientific scheduling of transportation vehicles (such as trucks, pump trucks, and conveyor belts) and route planning, avoiding delays or resource waste caused by supply disruptions. In the context of rapid urbanization, the material transportation system directly affects the construction quality and progress of municipal facilities such as roads, bridges, and pipelines, while simultaneously needing to consider environmental requirements (such as dust and noise control) and traffic management; it is a crucial link in balancing efficiency, cost, and social impact.
[0003] The existing technology has the following shortcomings: In the existing technology, the material conveying device for construction is disclosed in CN213735106U, which includes "a base; a side plate, the side plate being fixedly installed on the top of the base; a support seat, the support seat being disposed above the base; two baffles, the two baffles being symmetrically fixedly installed on the top of the support seat; a vertical plate, the vertical plate being hinged to the top of the support seat, the vertical plate being in contact with one side of the two baffles; and two disassembly mechanisms, the two disassembly mechanisms being symmetrically disposed on the top of the vertical plate".
[0004] The aforementioned equipment, through the inclusion of support bases, pedestals, and baffles, allows for easy movement, height adjustment, and reduced manpower, effectively minimizing labor intensity. However, this structure uses a drive roller and motor to automatically unload materials, requiring the material to be larger than the gap in the drive rollers for transport. Since construction materials vary in size, this structure cannot transport loose materials, resulting in a narrow range of applications. Furthermore, the conveying structure has numerous gaps and obstructions, creating many cleaning dead zones that hinder daily cleaning and maintenance, especially considering the loading container requires frequent cleaning. Utility Model Content
[0005] In view of the shortcomings of the existing technology, this utility model provides a material conveying device for building and municipal construction, which solves the current problems of being unable to transport scattered materials and the difficulty of cleaning.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a material conveying device for construction and municipal engineering, comprising a loading frame, support wheels, a handrail, and a control panel. The support wheels are disposed on both sides of the bottom of the loading frame, the handrail is disposed on the side of the loading frame, the control panel is disposed around the handrail, and a lifting cylinder is disposed at the upper middle part of the loading frame.
[0007] The top of the lifting cylinder is equipped with a self-unloading loading box, and the side of the self-unloading loading box is equipped with a discharge baffle.
[0008] The discharge baffle also includes a connecting shaft and a diffusion baffle. The connecting shaft is inserted into the two end faces of the discharge baffle, while the other side is movably connected to the side end of the self-unloading loading box. The diffusion baffle is welded to the two end faces of the self-unloading loading box.
[0009] As a preferred embodiment of this utility model, the diffusion baffle is provided in two sets, with each unit facing outward at a 45° angle.
[0010] As a preferred technical solution of this utility model, the self-unloading loading box further includes a trapezoidal partition plate, a positioning sleeve, a limiting rod, a motor, a locking stop rod, and a protective shell. The trapezoidal partition plate is welded to the bottom of the self-unloading loading box, and the positioning sleeve is welded to the two end faces of the self-unloading loading box and the loading vehicle frame.
[0011] As a preferred technical solution of this utility model, the trapezoidal partition plate has a hollow structure inside, with equal sides on both sides, an upper base length of 8cm, and is flush with the self-unloading loading box. The whole is made of stainless steel and is integrally die-cast.
[0012] As a preferred technical solution of this utility model, the limiting rod is provided in four sets, which respectively penetrate through the upper and lower positioning sleeves and establish an active connection with them. The motor is fixedly installed on the side of the self-unloading loading box, the locking stop is sleeved on the front end of the motor, and the protective shell is sleeved on the periphery of the motor.
[0013] As a preferred technical solution of this utility model, the maximum rotation angle of the discharge baffle is 150° supported by the connecting shafts on both sides, and it only rotates towards the outer sides of both ends of the loading frame.
[0014] As a preferred technical solution of this utility model, the locking stop bar is provided with a rectangular sheet structure on the side facing the feeding baffle and is closely attached to the outer end face of the feeding baffle.
[0015] Compared with the prior art, this utility model provides a material conveying device for building and municipal construction:
[0016] A material conveying device for construction and municipal engineering includes a self-unloading loading box, a discharge baffle, a connecting shaft, a trapezoidal partition, a locking bar, and limit bars. During operation, the operator controls the motor and lifting cylinder via a control panel. When loading material, the lifting cylinder moves downwards, and the upper self-unloading loading box moves synchronously downwards under the constraint of the surrounding limit bars until it reaches the end of its stroke, at which point the worker loads material into the loading box. After loading, the operator pushes the loading frame by holding the handle, moving it with the support wheels. When material needs to be discharged, the operator simply starts the motor, which in turn rotates the locking bar until it moves away from the discharge baffle. At this point, due to the slopes on both sides of the trapezoidal partition, the loaded material exerts pressure on both sides. Once the discharge baffle loses the obstruction of the locking lever, it immediately rotates under the pressure of the material. Supported by the connecting shaft, a large gap is created between the discharge baffle and the self-unloading loading box, allowing all the material to slide down the slope of the trapezoidal partition. During this process, the material scatters to both sides through the angled diffuser. After the material is unloaded, the discharge baffle returns to its original position under gravity and aligns with the self-unloading loading box. At this time, the motor controls the locking lever to reset and block the outside of the discharge baffle.
[0017] Through the above settings and procedures, the device achieves the following beneficial effects:
[0018] 1. Compared with existing construction and municipal construction material conveying devices, this equipment uses trapezoidal partitions, discharge baffles, and locking bars to unload from both sides instead of the existing horizontal unloading. The material is unloaded by gravity under the action of the slope. Compared with the existing method of unloading by motor-driven transmission rollers, the loading size of the material does not need to be greater than the transmission roller interval. It can load not only bagged whole materials, but also loose materials, thus improving the loading range of material conveying.
[0019] 2. Compared with the current material conveying devices used in construction and municipal engineering, the loading structure of this solution uses a smooth inclined surface structure with an internal area of more than 90% to replace the existing transmission rollers and transmission mechanism, which greatly reduces the dead corners for material cleaning and facilitates overall cleaning.

[0026] 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.
[0027] In this embodiment: a material conveying device for construction and municipal engineering includes a loading frame 1, support wheels 2, handrails 3 and control panel 4. The support wheels 2 are located on both sides of the bottom of the loading frame 1, the handrails 3 are located on the side of the loading frame 1, the control panel 4 is located around the handrails 3, and a lifting cylinder 5 is located at the upper middle part of the loading frame 1.
[0028] The top of the lifting cylinder 5 is equipped with a self-unloading loading box 6, and the side of the self-unloading loading box 6 is equipped with a discharge baffle 7.
[0029] The discharge baffle 7 also includes a connecting shaft 701 and a diffuser baffle 702. The connecting shaft 701 is inserted into the two end faces of the discharge baffle 7, while the other side is movably connected to the side end of the self-unloading loading box 6. The diffuser baffle 702 is welded to the two end faces of the self-unloading loading box 6.
[0030] In this embodiment, two sets of diffusion baffles 702 are provided, each of which is at a 45° outward angle; the self-unloading loading box 6 also includes a trapezoidal partition plate 601, a positioning sleeve 602, a limiting rod 603, a motor 604, a locking rod 605, and a protective shell 606. The trapezoidal partition plate 601 is welded to the bottom of the self-unloading loading box 6, and the positioning sleeve 602 is welded to the two end faces of the self-unloading loading box 6 and the loading frame 1.
[0031] Specifically, such as Figure 1 and Figure 4 As shown, the diffuser baffle 702 with a 45° outward angle can provide a shield for the bottom frame when the bulk material is unloaded, preventing loose material from falling into the gap of the support wheel 2 and affecting its rotation.
[0032] In this embodiment, the trapezoidal partition plate 601 has a hollow structure inside, with equal sides on both sides and an upper base length of 8cm, which is flush with the self-unloading loading box 6. The whole is made of stainless steel and is integrally die-cast. The limit rod 603 is provided with four sets, which pass through the positioning sleeves 602 of the upper and lower layers respectively and establish an active connection with them. The motor 604 is fixedly installed on the side of the self-unloading loading box 6, the locking stop 605 is sleeved on the front end of the motor 604, and the protective shell 606 is sleeved on the periphery of the motor 604.
[0033] Specifically, such as Figure 2 and Figure 4 as well as Figure 5 As shown, the trapezoidal partition plate 601 with equal sides on both sides makes the inclined surfaces on both sides the same. Due to the filling of material, the material below can be quickly discharged from both sides under pressure, which improves the material discharge speed and prevents blockage.
[0034] In this embodiment, the maximum rotation angle of the discharge baffle 7 is 150° supported by the connecting shafts 701 on both sides, and it only rotates towards the outer sides of both ends of the loading frame 1; the locking lever 605 is provided with a rectangular plate structure on the side facing the discharge baffle 7, and is closely attached to the outer end face of the discharge baffle 7.
[0035] Specifically, such as Figure 3 and Figure 5 As shown, the rectangular plate structure on the side of the locking lever 605 can increase the contact area with the self-unloading loading box 6, thereby evenly dispersing the inner pressure of the discharge baffle 7 and maintaining the overall stability of this part of the structure.
[0036] The working principle and usage process of this utility model are as follows: When using this equipment, the operator controls the operation of the motor 604 and the lifting cylinder 5 through the control panel 4. During material loading, the lifting cylinder 5 moves downwards, and the upper self-unloading loading box 6 moves downwards synchronously under the limiting of the surrounding limit rods 603 until it reaches the end of its stroke, at which point the worker loads material into the self-unloading loading box 6. After loading is complete, the operator pushes the loading frame 1 by holding the handle 3, and it moves under the support of the support wheels 2. When material needs to be unloaded, the operator only needs to start the motor 604, which controls the locking lever 605 to rotate until the locking lever 605 moves away from the unloading baffle 7. At this time, due to the slopes on both sides of the trapezoidal partition 601, the loaded material exerts pressure on both sides. After the discharge baffle 7 loses the obstruction of the locking lever 605, it immediately rotates under the pressure of the material. A large gap is created between the discharge baffle 7 and the self-unloading loading box 6 through the support of the connecting shaft 701. All the material slides down through the slope of the trapezoidal partition 601. During this process, the material is scattered on both sides through the angle of the diffuser baffle 702. After the material is unloaded, the discharge baffle 7 returns to its original position under the action of gravity and is aligned with the self-unloading loading box 6. At this time, the motor 604 controls the locking lever 605 to reset and block the outside of the discharge baffle 7.
[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
