Technical Field
[0001] The utility model belongs to the technical field of small concrete transport vehicles, and particularly relates to a small concrete transport vehicle with convenient use. Background Technique
[0002] Concrete is one of the most important civil engineering materials in the contemporary era. It is a kind of artificial stone prepared by mixing cementitious materials, granular aggregates, water, and additives and admixtures added when necessary in a certain proportion, uniformly stirred, densely formed, and cured and hardened. Concrete has the characteristics of rich raw materials, low price, and simple production process, so its usage is increasing.
[0003] At present, when the concrete transport vehicle dumps, it is necessary for workers to tilt the vehicle body manually, and then let the hopper rotate and unload by its own gravity. During transportation, the stability of the hopper is poor and it is easy to overturn. Moreover, after unloading, the hopper needs to be restored manually by workers, with poor convenience, which is not only time-consuming and laborious, but also affects work efficiency. Content of the Utility Model
[0004] To solve the problems raised in the above background technique, the utility model provides a small concrete transport vehicle with convenient use, including a moving support for movement, a hopper for transporting concrete, a limiting mechanism arranged on the moving support, and an automatic loading and unloading mechanism arranged between the moving support and the hopper.
[0005] The limiting mechanism includes a pair of bearing seats and columns fixed on the moving support, and a hook seat fixed on the hopper.
[0006] As a small concrete transport vehicle with convenient use of the utility model, preferably, a rotating rod is movably arranged on the two bearing seats, a hook matching the hook seat is fixedly arranged at the center of the rotating rod, and a rotating handle is fixed at the left end of the rotating rod.
[0007] As a small concrete transport vehicle with convenient use of the utility model, preferably, the rotating handle is connected to the column through a tension spring.
[0008] As a small concrete transport vehicle with convenient use of the utility model, preferably, the automatic loading and unloading mechanism includes a pair of first bearing seats and a motor bracket fixed on the moving support, and a plurality of limiting columns arranged in an array at both ends of the moving support.
[0009] As a small concrete transport vehicle with convenient use of the utility model, preferably, a rotating shaft is movably arranged on the first bearing seat, arc-shaped rotating seats are fixedly arranged at both ends of the rotating shaft, the arc-shaped rotating seats are fixedly connected to the bottom of the hopper, and a plurality of limiting holes matching the limiting columns are opened on the arc-shaped rotating seats.
[0010] As a small concrete transporter with convenient use in the utility model, preferably, a driven gear is fixedly arranged on the rotating shaft, a reduction motor is fixed on the motor bracket, and a driving gear meshing with the driven gear is fixed on the rotor of the reduction motor.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] Through the pulling force of the tension spring, the rotating handle is pulled to rotate counterclockwise, driving the pulling hook to be clamped on the hook seat for limiting, improving the stability of the material transportation hopper during transportation. Driving the rotation of the reduction motor drives the driving gear to rotate. Since the driving gear meshes with the driven gear, at this time, the rotating shaft is driven to rotate by the driven gear, and then the material transportation hopper is driven to perform automatic unloading and restoration operations through the arc-shaped rotating seat, which is time-saving and labor-saving and is relatively convenient to use.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0024] Embodiment 1
[0025] As Figure 1 shown;
[0026] A small concrete transport vehicle with convenient use, including a moving support 1 for movement and a transport hopper 3 for transporting concrete.
[0027] In this implementation scheme: To solve the technical problems existing in this prior art, as disclosed in the background art above, "Currently, when a concrete transport vehicle dumps, it is necessary to manually tilt the vehicle body with force, and then let the transport hopper rotate and unload by its own gravity. During transportation, the stability of the transport hopper is poor, and it is easy to overturn. Moreover, after unloading, the transport hopper needs to be manually restored by workers, with poor convenience, which is not only time-consuming and laborious but also affects work efficiency." In combination with actual use, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, a limiting mechanism 2 and an automatic loading and unloading mechanism 4 are added on this basis.
[0028] As Figures 1-4 shown in the figure;
[0029] Combined with the above content, in order to improve the stability of the transport hopper of the transport vehicle and its convenience of use, it further includes a limiting mechanism 2 provided on the moving support 1 and an automatic loading and unloading mechanism 4 provided between the moving support 1 and the transport hopper 3;
[0030] The limiting mechanism 2 includes a pair of bearing seats 21 and a support column 22 fixed on the moving support 1, and a hook seat 23 fixed on the transport hopper 3.
[0031] In an optional embodiment, a rotating rod 24 is movably provided on the two bearing seats 21. A hook 25 matching the hook seat 23 is fixedly provided at the center of the rotating rod 24. A rotating handle 26 is fixed at the left end of the rotating rod 24, and the rotating handle 26 is connected to the support column 22 through a tension spring 27.
[0032] In this embodiment: By the pulling force of the tension spring 27, the rotating handle 26 is pulled to rotate counterclockwise, driving the pulling hook 25 to be clamped on the hook seat 23 for limiting, improving the stability of the material transporting hopper 3 during transportation. The rotating handle 26 drives the rotating rod 24 to rotate and stretches the tension spring 27. At this time, the hook 25 rotates with the rotating rod, causing it to disengage from the hook seat 23, completing the release of the limit.
[0033] In an alternative embodiment, the automatic loading and unloading mechanism 4 includes a pair of first bearing seats 41 and a motor bracket 42 fixedly arranged on the moving support 1, and a number of limit posts 43 arrayed at both ends of the moving support 1. A rotating shaft 44 is movably arranged on the first bearing seats 41. Arc-shaped rotating seats 45 are fixedly arranged at both ends of the rotating shaft 44. The arc-shaped rotating seats 45 are fixedly connected to the bottom of the material transporting hopper 3. A number of limit holes 46 matching the limit posts 43 are formed in the arc-shaped rotating seats 45. A driven gear 47 is fixedly arranged on the rotating shaft 44. A reduction motor 48 is fixed on the motor bracket 42. A driving gear 49 meshing with the driven gear 47 is fixed on the rotor of the reduction motor 48.
[0034] In this embodiment: Driving the rotation of the reduction motor 44 drives the driving gear 49 to rotate. Since the driving gear 49 meshes with the driven gear 47, at this time, the rotating shaft 44 is driven to rotate through the driven gear 47, and then the material transporting hopper 3 is driven to perform automatic unloading and restoration operations through the arc-shaped rotating seats 45, which is time-saving and labor-saving and is relatively convenient to use.
[0035] The working principle of the present utility model:
[0036] By the pulling force of the tension spring 27, the rotating handle 26 is pulled to rotate counterclockwise, driving the pulling hook 25 to be clamped on the hook seat 23 for limiting, improving the stability of the material transporting hopper 3 during transportation. The rotating handle 26 drives the rotating rod 24 to rotate and stretches the tension spring 27. At this time, the hook 25 rotates with the rotating rod, causing it to disengage from the hook seat 23, completing the release of the limit. Driving the rotation of the reduction motor 44 drives the driving gear 49 to rotate. Since the driving gear 49 meshes with the driven gear 47, at this time, the rotating shaft 44 is driven to rotate through the driven gear 47, and then the material transporting hopper 3 is driven to perform automatic unloading and restoration operations through the arc-shaped rotating seats 45, which is time-saving and labor-saving and is relatively convenient to use.
[0037] Finally, it should be noted that: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded 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 utility model shall be included in the protection scope of the present utility model.
