Description

Technical Field

[0001] This invention relates to the field of mixer truck technology, specifically to a horizontally mounted four-bladed turbine-type isolation chamber mixer truck equipped with a feeding and discharging device and the mixer truck itself. Background Technology

[0002] Existing concrete mixer trucks use a design with opposing double augers inside the tank, which has the following drawbacks:

[0003] 1. Insufficient flow and rotation of concrete can easily cause segregation of ready-mixed concrete during transportation, affecting the quality of the concrete.

[0004] 2. If the concrete mixer truck tank is not sealed, it is easy for moisture to escape. If not careful during transportation, the concrete may solidify, resulting in a "sealed tank" accident. If the "sealed tank" is not cleaned in time, the tank will be scrapped.

[0005] 3. If the concrete feeding speed in the concrete mixer truck is not fast, it will lead to leakage. If the material cannot be completely discharged, concrete residue will remain in the tank, making cleaning difficult.

[0006] 4. Due to the open design of the feed conduit pipe leading directly to the tank cavity, material leakage is frequent, resulting in wasted concrete and road pollution.

[0007] According to a published patent (CN 203318243 U), a concrete mixer truck with a horizontal self-enclosed structure that uses an agitator to solve the problem of material loading and unloading was launched by Shiyan Tianze Special Vehicle Technology Co., Ltd. However, it still uses the traditional double-blade agitator. The double-blade agitator makes it difficult to load and unload materials due to the narrow channel and excessive curve radius inside the agitator, making it difficult to achieve the horizontal self-enclosed concrete transport function. The loading of concrete in the tank cannot effectively improve the loading efficiency of the tank, and the loading capacity is not much different from that of traditional concrete mixer trucks. Summary of the Invention

[0008] In view of the deficiencies in the existing technology, the purpose of this invention is to provide a flat-mounted four-bladed turbine-type isolation silo mixer truck with an inlet and outlet device and a mixer truck, which increases the fluidity of concrete in the tank and ensures that concrete will not settle and segregate during transportation.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a horizontally mounted four-bladed turbine-type isolation chamber mixer truck equipped with a feeding and discharging device, including a horizontally arranged mixing tank and a vortex shell; the rear end of the mixing tank is an open structure; the vortex shell is used to close the open end of the mixing tank, and a vortex bottom shell plate is provided at the connection between the vortex shell and the mixing tank; the vortex bottom shell plate is used to separate the inner cavity of the mixing tank and the inner cavity of the vortex shell, and several vortex bottom inlet and outlet ports for connecting the inner cavity of the mixing tank and the inner cavity of the vortex shell are provided on the four periphery of the vortex bottom shell plate; several turbine blades are provided in the inner cavity of the vortex shell; the vortex shell is also provided with inlet and outlet ports for connecting to the outside.

[0010] A further improvement is that the inner wall of the mixing tank is provided with a spiral auger.

[0011] A further improvement is that a guide vortex cone is provided at the center of one side of the vortex shell plate, and each turbine blade is symmetrically distributed with respect to the center of the guide vortex cone.

[0012] Further improvements include: the turbine blades are arc-shaped curved blades, one end of the turbine blades faces the guide vortex cone, and the other end of the turbine blades extends to the edge of the vortex bottom shell plate; and a vortex bottom inlet / outlet is provided between each pair of adjacent turbine blades.

[0013] A further improvement is that the inlet and outlet are located at the center of the outer side of the vortex shell, and the inner wall of the inlet and outlet is provided with several spiral blades.

[0014] The present invention also provides a mixer truck, including a chassis and a subframe, wherein the subframe is provided with a loading and unloading device as described above for a horizontally mounted four-bladed turbine-type isolation compartment mixer truck.

[0015] A further improvement is that the chassis is equipped with an oil pump, and the front end of the subframe is equipped with a full-power power take-off.

[0016] A further improvement is that the rear end of the subframe is provided with a rear support system for supporting the mixing tank and a rear drive system for driving the mixing tank.

[0017] A further improvement is that a front support seat is provided at the front end of the subframe, and a hydraulic motor and a water tank are provided on the front support seat.

[0018] A further improvement is that a support roller for supporting the mixing tank is provided in the middle of the subframe.

[0019] The beneficial effects of this invention are as follows:

[0020] Compared to the traditional two-headed spiral mixing of concrete mixing tanks, this invention adds a four-headed spiral mixing, maximizing the fluidity of concrete within the tank and ensuring that the concrete does not settle or segregate during transportation. A vortex-bottom shell is added at the end of the tank as an isolation plate, isolating the concrete from the atmosphere and preventing moisture evaporation, thus ensuring the correct concrete moisture content. Four vortex-bottom inlet and outlet ports are evenly distributed around the mixing end around the isolation plate, ensuring that the feeding and discharging speeds meet the design requirements of the mixer truck. A four-vortex fan waterwheel structure is formed within the sealed isolation chamber, balancing the rotational inertia during discharge while maximizing the propulsion of feed and the lifting of discharge. The inlet and outlet ports have a built-in four-blade structure to ensure that feed does not flow back and discharge does not accumulate in the isolation chamber. Attached Figure Description

They should not be construed as limiting the specific protection scope of this invention.

[0039] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and its beneficial effects clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the invention.

[0040] See Figures 1-5 As shown, this embodiment of the invention provides a loading and unloading device for a horizontally mounted four-bladed turbine-type isolation chamber mixer truck, including a horizontally arranged mixing tank 101 and a vortex shell 102; the rear end of the mixing tank 101 is an open structure; the vortex shell 102 is used to close the open end of the mixing tank 101, and a vortex bottom shell plate 103 is provided at the connection between the vortex shell 102 and the mixing tank 101; the vortex bottom shell plate 103 is used to separate the inner cavity of the mixing tank 101 and the inner cavity of the vortex shell 102, and a plurality of vortex bottom inlet and outlet ports 104 for connecting the inner cavity of the mixing tank 101 and the inner cavity of the vortex shell 102 are provided on the four periphery of the vortex bottom shell plate 103; a plurality of turbine blades 105 are provided in the inner cavity of the vortex shell 102; the vortex shell 102 is also provided with an inlet and outlet port 106 for connecting to the outside.

[0041] Specifically, the inner wall of the mixing tank 101 is provided with a spiral auger 109, which is a spiral blade structure welded to the inner wall of the tank, with four spiral welded ends. In this embodiment, four spiral augers are uniformly welded to the inner wall of the mixing tank, running through the front and back.

[0042] Specifically, a guide vortex cone 108 is provided at the center of the bottom shell plate 103 on one side of the vortex shell 102. The guide vortex cone forms a vortex of inlet and outlet fluid, which promotes and accelerates the speed of inlet and outlet. Each vortex fan blade 105 is symmetrically distributed with respect to the center of the guide vortex cone 108.

[0043] Specifically, the turbofan blade 105 is an arc-shaped curved blade, with one end of the turbofan blade 105 pointing towards the guide vortex cone 108, and the other end of the turbofan blade 105 extending to the edge of the vortex bottom shell plate 103; and a vortex bottom inlet / outlet 104 is provided between each pair of adjacent turbofan blades 105, the vortex bottom inlet / outlet 104 having a near-trapezoidal hole structure. In this embodiment, four turbofan blades are evenly distributed on the vortex bottom shell plate, and four vortex bottom inlet / outlet ports are distributed around the vortex bottom shell plate.

[0044] Specifically, the inlet / outlet 106 is located at the center of the outer side of the vortex shell 102, and the inner wall of the inlet / outlet 106 is provided with several spiral blades 107 for stirring the concrete inlet / outlet.

[0045] See Figure 6 As shown, during feeding, concrete is fed into the inlet and outlet through the feed funnel. Under the combined action of gravity and the helical thrust of the four-bladed turbine, the concrete enters the vortex shell and falls into the bottom of the isolation chamber formed by the vortex shell and its base. The concrete at the bottom of the isolation chamber is then guided to a higher point by the flow-guiding cone and the "waterwheel" structure composed of the turbine fan, vortex shell, and vortex base shell, and enters the mixing tank through the vortex base inlet and outlet. Details are as follows... Figure 4 As shown, concrete is fed from feed hopper I into inlet / outlet II, propelled by four blades into the vortex shell, and then enters the bottom of the isolation chamber via position III. Driven by the rotation of the turbine fan, it passes through position IV and enters the mixing tank at position VI during rotation. Before reaching the highest point of the isolation chamber at position V, most of the material in the turbine fan will enter the mixing tank, with a very small portion falling to the bottom of the vortex shell and being transported to the mixing tank by the next "waterwheel".

[0046] See Figure 7 As shown, inside the mixing tank, the concrete is subjected to the combined force of the stirring screw and the concrete's viscosity, resulting in the following action: Figure 7 The cyclic stirring is shown.

[0047] During discharge, the concrete travels in the opposite direction to the feed path.

[0048] See Figure 8As shown, this embodiment of the invention also provides a mixer truck, including a chassis 2 and a subframe 3. The subframe 3 is equipped with a loading and unloading device 1, as described above, for a horizontally mounted four-bladed turbine-type isolation chamber mixer truck. Specifically, the chassis 2 is equipped with an oil pump 21, and the front end of the subframe 3 is equipped with a full-power power take-off 6. The rear end of the subframe 3 is equipped with a rear support system 4 for supporting the mixing tank 101 and a rear drive system 5 for driving the mixing tank 101. The front end of the subframe 3 is equipped with a front support seat 7, on which a hydraulic motor 71 and a water tank 72 are mounted. The middle part of the subframe 3 is equipped with a support roller 31 for supporting the mixing tank 101.
