Description

Technical Field

[0001] The utility model belongs to the field of concrete mixer trucks, and in particular relates to a material blocking structure in a tank of a mixer truck. Background Art

[0002] The tank structure of a concrete mixer truck plays an extremely important role in the use of concrete mixer trucks. In the field of concrete mixer truck installation, in addition to the tank loading capacity, the requirements for the concrete mixer truck tank also focus on comprehensive indicators such as weight, wear resistance, and loading and unloading efficiency.

[0003] At present, the tank body of a concrete mixer truck mostly adopts multi-layer spiral hollow blades. The slurry enters from the hollow part of one end of the blade. In order to ensure that the slurry does not solidify, the blade keeps rotating and stirring during the process. Combined with the vibration generated during vehicle transportation, the slurry may splash outward. Therefore, requirements are made on the actual loading capacity. By limiting the maximum loading capacity, the slurry cannot splash out of the vehicle body. Therefore, the space utilization rate in the tank body is not high. In order to increase the maximum loading capacity, the existing technology mostly ensures the volume by lengthening the tank body. However, there are problems such as large space occupation, high dead weight, and low loading and unloading efficiency. Utility Model Content

[0004] In order to solve the problems that slurry in a mixer truck is easy to splash and the space utilization rate in the tank body is low, the utility model provides a material blocking structure in the tank body of a mixer truck.

[0005] The purpose of the utility model is achieved in the following way: a material blocking structure in the tank body of a mixer truck, including a spiral blade 20 with a hollow middle, a feed cone 10 is arranged at the front end of the spiral blade 20, the feed cone 10 is fixed to the inner edge of the spiral blade 20, and a feed port 11 is formed at the front end of the feed cone 10, and a material blocking structure is arranged behind the feed cone 10, and the material blocking structure is arranged inward from the inner edge of the spiral blade 20; the projection of the material blocking structure along the axial direction of the spiral blade 20 covers the projection of the hollow part between the inner edges of the spiral blades 20 connected to the material blocking structure along the axial direction of the spiral blade 20.

[0006] Furthermore, the material blocking structure includes an annular mounting frame 3, the outer edge of the mounting frame 3 extends the transition blade 2 toward the inner edge of the spiral blade 20, the end of the transition blade 2 is fixedly connected to the inner edge of the spiral blade 20, and a partition 1 is detachably connected to one side of the mounting frame 3.

[0007] Furthermore, mounting holes are arranged in an array on the periphery of the partition 1, and fixing holes matching the mounting holes are arranged on the mounting frame 3. The partition 1 and the mounting frame 3 are fixedly connected by connecting pieces passing through the mounting holes and the fixing holes.

[0008] Furthermore, at least one paddle hole 4 is provided near the center of the partition 1, and the diameter of the paddle hole 4 is less than 80 mm.

[0009] Compared with the prior art, the present invention effectively blocks part of the splashing slurry by arranging a baffle in the spiral blade near the feed port, thereby increasing the actual loading capacity of the mixer truck. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] In the present invention, unless otherwise expressly specified and limited, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation to the present invention.

[0015] As attached Figure 1-2 As shown, a material retaining structure in the tank of a mixer truck includes a spiral blade 20 with a hollow center, a feed cone 10 is arranged at the front end of the spiral blade 20, the feed cone 10 is fixed to the inner edge of the spiral blade 20, and a feed port 11 is formed at the front end of the feed cone 10, which is characterized in that a material retaining structure is arranged behind the feed cone 10, and the material retaining structure is arranged inward from the inner edge of the spiral blade 20; the projection of the material retaining structure along the axial direction of the spiral blade 20 covers the projection of the hollow part between the inner edges of the spiral blades 20 to which the material retaining structure is connected along the axial direction of the spiral blade 20.

[0016] The structure of the feed cone 10 and the spiral blade 20 is the existing technology. The spiral blade 20 can be a single one, but preferably a double spiral blade 20 is cross-arranged.

[0017] In detail, "the projection of the hollow part between the inner edges of the spiral blades 20 along the axial direction of the spiral blades 20" refers to the position of the inner edge of the spiral blade 20 to which the material blocking structure is connected, and the projection of the hollow part formed by the front and rear spiral structures. This structure is set to block the slurry that is most likely to splash out from the hollow part of the spiral blade 20.

[0018] It should be noted that the retaining structure does not have a sealing effect, but only serves to retain slurry at a certain speed. In actual use, slurry may overflow to the front of the retaining structure, but will also flow back as the spiral blade 20 continues to rotate.

[0019] The material blocking structure is preferably arranged at the position of the spiral structure of the spiral blade 20 1-1.5 turns after the tail end of the feed cone 10. On the one hand, it does not hinder the feeding and discharging of materials. On the other hand, the closer it is to the feed cone 10, the better the effect of increasing the volume. In fact, the stirring capacity of the mixer truck is increased by 0.5m³.

[0020] Furthermore, the material blocking structure includes an annular mounting frame 3, which is preferably a circular frame. The outer edge of the mounting frame 3 extends the transition blade 2 toward the inner edge of the spiral blade 20, and the end of the transition blade 2 is fixedly connected to the inner edge of the spiral blade 20. Preferably, the end of the transition blade 2 is fixedly connected to the end of the inner edge of the spiral blade 20, so that no corner is formed between the transition blade 2 and the spiral blade 20, preventing slurry residue from agglomerating. A partition 1 is detachably connected to one side of the mounting frame 3.

[0021] Furthermore, the partition 1 is provided with an array of mounting holes on its periphery, and the mounting frame 3 is provided with fixing holes that match the mounting holes. The partition 1 and the mounting frame 3 are fixedly connected by connecting members passing through the mounting holes and the fixing holes, and the connecting members are preferably bolts.

[0022] Furthermore, at least one paddle hole 4 is provided near the center of the partition 1. "Close to the center" means that when there is one paddle hole 4, it is provided in the middle; when there are more than one paddle holes 4, the other paddle holes 4 are provided in a circular array around the central paddle hole 4 and are not 500 mm away from the midpoint; and the diameter of the paddle hole 4 is less than 80 mm.

[0023] The purpose of the "detachable connection" and the "paddle hole 4" is that a thin slurry will gradually precipitate out of the upper layer of concrete with better fluidity. When there is no paddle hole 4, the slurry will constantly contact the back of the partition 1 and agglomerate quickly, which requires frequent cleaning. By providing the paddle hole 4, part of the slurry can flow through the partition 1 to the front side; even if the paddle hole 4 is provided to alleviate the above situation, the back of the partition 1 will still gradually agglomerate. The detachable connection allows the partition 1 to be removed and cleaned.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
