Abstract
Description
Technical Field
[0001] The utility model relates to the field of concrete transport trolleys, and in particular to a hand-push concrete transfer trolley. Background Art
[0002] Concrete is the most commonly used building material. In most cases, it is transported to the pouring site by a pump truck or ground pump. However, due to limited conditions, it is sometimes transported by a wheelbarrow. The commonly used two-wheeled wheelbarrows have a small loading capacity, inconvenient unloading, and require manual shovels. The unloading speed is slow. When using a self-unloading bucket, it is impossible to accurately control the amount of concrete dumping. The bucket is square, and the amount of residue in the corners is large, which is difficult to clean. In addition, the structural strength is insufficient, the failure rate is high, the stability is poor, and it is easy to overturn and scatter materials. The flexibility is poor, the operation in a small space is limited, the turning is not flexible enough, and the support legs are thin. When the cart stops on a soft road, the support legs will sink into the soil, which not only makes the support effect of the support legs poor, but also makes it difficult to pull out the support legs. Due to the above shortcomings, it often causes an increase in construction time and waste of materials. Summary of the invention
[0003] In view of the shortcomings of the above-mentioned traditional concrete transport vehicles, a hand-push concrete transfer vehicle is provided. The concrete hand-push vehicle designed by the utility model has a loading capacity two to three times that of the traditional two-wheeled hand-push vehicle, and the hopper adopts a funnel shape, with feeding at the top and self-flowing discharge at the bottom, which is convenient for loading and unloading, and there is no dead angle on the inner wall of the hopper, which effectively solves the problem of material residue. The hopper door adopts a "gate" method, which can accurately control the discharge flow rate and flow rate.
[0004] The technical means adopted by the utility model are as follows:
[0005] A hand-pushed concrete transfer vehicle comprises: a wheel mechanism, a steering device, a frame device, a hopper, and a discharge door device;
[0006] The frame device is a core component, and a switch handle is installed on the upper part of the frame device, and the switch handle is formed by bending a round tube;
[0007] The wheel mechanism is arranged at the lower side of the frame device, and the steering device is arranged at the rear wheel of the wheel mechanism;
[0008] The hopper is arranged on the upper side of the frame device, and its shape is a deformed circular funnel, the inner wall is smooth, there is no dead angle, and the inclination angle with the horizontal ground is 40°. The discharge door device is located at the lower discharge port of the hopper, and the discharge door device is connected to the switch handle by a connecting rod device;
[0009] The wheel mechanism, steering device, hopper and discharge door device are all welded to the frame device by channel steel.
[0010] Furthermore, the wheel mechanism is in the form of three wheels, the front wheels are double wheels, and the rear wheels are single wheels. The front wheels are fixed load-bearing wheels fixed to the front side of the frame device through bearings; the rear wheels are steering wheels fixed to the steering device through bearings.
[0011] Furthermore, the steering device is fixed on the frame device, and can realize 360-degree steering of the loading vehicle.
[0012] Furthermore, the hopper body is made of 3 mm thick steel plate and is connected to the frame device through fixing parts.
[0013] Furthermore, the discharge door device is arranged at the lower end of the hopper. The discharge door device is in the form of a gate and is connected to the frame through a T-shaped fixing. One end of the T-shaped fixing is connected to the switch handle through a connecting rod. The opening and closing of the discharge door is controlled by the switch handle. A strong spring is arranged at the other end to provide a certain amount of assistance when opening the discharge door.
[0014] Due to the adoption of the above technical solution, compared with the prior art, the utility model has the following advantages:
[0015] 1. The hand-pushed concrete transfer vehicle provided by the utility model has a larger loading capacity than the traditional concrete transport wheelbarrow, which is two to three times the loading capacity of the traditional two-wheeled wheelbarrow.
[0016] 2. The utility model provides a hand-push concrete transfer vehicle, which adopts a funnel-shaped hopper, with material feeding at the top and material discharge at the bottom by gravity. Loading and unloading is convenient and quick, and there is no dead angle on the inner wall of the hopper, which effectively solves the problem of material residue.
[0017] 3. The utility model provides a hand-push concrete transfer vehicle, in which the hopper door adopts a "gate" method, which can accurately control the discharge flow rate and flow rate. The hopper door is connected by a connecting rod device, and a switch handle is set at the handle of the cart, which is manually controlled by the worker to avoid direct contact with concrete when opening and closing the hopper door, thereby effectively improving the working conditions.
[0018] 4. The utility model provides a hand-pushed concrete transfer vehicle, which adopts front load-bearing wheels and rear steering wheels to reduce the turning radius and improve the vehicle's flexibility and applicability in narrow spaces.
[0019] Based on the above reasons, the utility model can be widely promoted in the field of concrete transport trolleys. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0030] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0031] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0032] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0033] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0034] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
