Description
Technical Field
[0001] This application relates to the field of concrete construction, and particularly to a concrete mixer truck. Background Art
[0002] The full name of a concrete mixer truck is a concrete mixing and transporting truck, which is a special truck used to transport mixed construction concrete; due to its shape, it is often also called a snail truck. Such trucks are equipped with a cylindrical mixing drum to carry the mixed concrete. During transportation, the mixing drum will always rotate to ensure that the transported concrete does not solidify. After transporting the concrete, the inside of the mixing drum is usually washed with water to prevent the hardened concrete from occupying space and reducing the volume of the mixing drum.
[0003] Existing concrete mixer trucks generally include a vehicle body with a hopper and a mixing tank installed on the hopper. In order to transport more concrete, existing concrete mixer trucks are generally semi-trailers, and the size of the mixing tank is generally large. Such concrete mixer trucks can only be used in large construction sites. When the demand for concrete is small, it is not cost-effective for the whole vehicle to run. At the same time, due to the need for the mixing tank to rotate continuously as a whole, the energy consumption is also high.
[0004] In order to adapt to different situations and transport different amounts of concrete reasonably, a different type of concrete mixer truck is needed. Utility Model Content
[0005] In order to transport different cubic meters of concrete reasonably, this application provides a concrete mixer truck.
[0006] The concrete mixer truck provided by this application adopts the following technical solutions:
[0007] A concrete mixer truck includes a vehicle body with a hopper and a concrete mixing device arranged on the hopper. There are multiple concrete mixing devices, and the multiple concrete mixing devices are arranged on the hopper. The concrete mixing device includes a mixing tank, a mixing driving member, mixing fan blades and a bracket. The mixing tank is installed on the bracket and is provided with a concrete discharge port at the bottom. The mixing fan blades are arranged inside the mixing tank, and the mixing driving member is installed on the mixing tank and drives the mixing fan blades to rotate.
[0008] By adopting the above technical solution, the capacity of the mixing tank for holding concrete is reduced. However, by arranging a plurality of concrete mixing devices on the carriage, the plurality of mixing tanks are combined to form sufficient concrete transportation. At the same time, since the plurality of concrete mixing devices are independent of each other, different numbers of concrete mixing devices can be transported each time according to the demand for concrete. Correspondingly, the size of the carriage of the vehicle body can also be changed according to the number of concrete mixing devices, with stronger adaptability. At the same time, since the size of the mixing tank of the concrete mixing device is reduced, stirring can be carried out by rotating the stirring fan blades, which is safer and more energy-saving compared to rotating the entire mixing tank.
[0009] Optionally, a concrete feeding component is also provided. The concrete feeding component includes a feeding pipe, a spiral blade, and a feeding driving member. One end of the feeding pipe is communicated with the concrete discharge port of the mixing tank, and the other end is provided with a feeding port. The spiral blade is installed in the feeding pipe and is driven to rotate by the feeding driving member.
[0010] By adopting the above technical solution, the supporting concrete feeding component enables the concrete mixing device to be used independently. When a single concrete mixing device is transported in place, the concrete mixing device can be externally connected to the concrete feeding component, and then continue to output raw materials into the mixing tank for stirring. At the same time, the feeding driving member drives the spiral blade to rotate, and the spiral blade drives the concrete in the feeding pipe to continuously move to the feeding port for feeding. Compared with directly feeding from the mixing tank, the concrete is not easily interfered by the support when being received.
[0011] Optionally, the concrete feeding component further includes a connecting member and a height-adjustable support member. The connecting member includes a rubber main body and a flange connecting piece. The connecting member is flange-connected to the mixing tank, the connecting member is flange-connected to the feeding pipe, the feeding pipe is rotationally matched with the support, and the height-adjustable support member is rotationally matched with the feeding pipe and supports the feeding pipe.
[0012] By adopting the above technical solution, the feeding pipe is supported by the height-adjustable support member, so that the feeding port of the feeding pipe is relatively high, which is beneficial to receiving concrete. At the same time, due to the height-adjustable characteristic of the height-adjustable support member, the deformable characteristic of the rubber main body of the connecting member, and the rotational matching between the feeding pipe and the support and the height-adjustable support member, the height of the feeding pipe can be adjusted according to requirements.
[0013] Optionally, the stirring fan blade includes a cross-shaped main body and extending blades. The cross-shaped main body is provided with four stirring ends, and there are four extending blades. The four extending blades correspond to the four stirring ends one by one. One end of the extending blade is fixed to the stirring end, and the other end extends obliquely. The lengths of the four extending blades are different.
[0014] By adopting the above technical solution, the four extended blades of the stirring fan blade are inclined and have different lengths, which can achieve a better stirring effect on the concrete. The extended blades with different lengths alternately push the concrete in different layers, forming a better disturbance.
[0015] Optionally, the extended blade is provided with diversion holes, and there are a plurality of the diversion holes, and the plurality of diversion holes are arranged at intervals.
[0016] By adopting the above technical solution, the extended blade is provided with diversion holes, which can better disturb the concrete and also reduce the resistance received by the extended blade.
[0017] Optionally, the concrete mixing device further includes a flow dividing box, which is installed in the upper part of the mixing tank. The flow dividing box is annular and is provided with an annular flow channel. The flow dividing box is coaxial with the mixing tank, and the flow dividing box is provided with a water pipe extending out of the mixing tank and communicating with the annular flow channel.
[0018] By adopting the above technical solution, a flow dividing box is provided and water is externally connected. Water is sprinkled into the mixing tank more evenly through the flow dividing box, so that the concrete can be mixed faster during the mixing process. At the same time, during the transportation process, the water evaporated and lost in the mixing tank can be evenly supplemented.
[0019] Optionally, a drain pipe extending out of the mixing tank is further provided at the bottom of the flow dividing box.
[0020] By adopting the above technical solution, the drain pipe is provided, so that when too much supplementary water is present, it can flow away through the drain pipe. At the same time, when supplementing water, enough water can quickly flow into the flow dividing box to spread faster, and then the excess water can be discharged through the drain pipe.
[0021] Optionally, a part of the drain pipe is located below the annular flow channel and is closed.
[0022] By adopting the above technical solution, the drain pipe can drain the water at the bottommost part of the annular flow channel, and the drainage effect is better.
[0023] In summary, by reducing the capacity of the mixing tank for holding concrete, but by arranging a plurality of concrete mixing devices on the truck bed, a sufficient amount of concrete can be transported by combining a plurality of mixing tanks. At the same time, since the plurality of concrete mixing devices are independent of each other, different numbers of concrete mixing devices can be transported each time according to the demand for concrete, and the size of the truck bed of the corresponding vehicle body can also be changed according to the number of concrete mixing devices, with stronger adaptability. At the same time, since the size of the mixing tank of the concrete mixing device is reduced, stirring can be carried out by rotating the stirring fan blade, which is safer and more energy-saving compared to rotating the entire mixing tank.
