Description

Technical Field

[0001] The invention relates to the technical field of construction machinery, and in particular to an easy-to-drain concrete mixing drum. Background Art

[0002] Concrete is a man-made material formed by mixing cement, water, sand, gravel and other main materials in appropriate proportions, compacting and curing. It is one of the most common materials in civil engineering and is widely used in housing construction, bridges, roads and other fields. In daily concrete production, it is often necessary to use a concrete mixer to mix the materials that make up the concrete evenly. The concrete mixer is mainly composed of a mixing drum, a feeding and unloading mechanism, a water supply system, a prime mover, a transmission mechanism, a frame and a supporting device. The concrete mixing drum is a mixing container for concrete, usually an integrated structure. For many large concrete mixers, the rotating space of the concrete mixing drum is limited, and a large amount of sewage cannot be discharged quickly and accurately to the designated location. After cleaning, there will still be a large amount of concrete and sewage remaining. Workers are usually required to use smaller containers to clean the sewage and concrete remaining in the concrete mixing drum again, which is difficult, time-consuming and low in cleaning degree. Untreated concrete and sewage will not only affect the re-production of the concrete mixer, but also reduce the life of the concrete mixer. In actual projects, due to incomplete cleaning of the concrete mixing drum, it is necessary to regularly clean the concrete mixing drum, which is not only time-consuming but also incurs additional costs.

[0003] Patent document CN205364225U discloses a concrete mixing tank. The key point of the scheme is a concrete mixing tank, including a tank body, which is tilted and arranged on a concrete mixing truck. The tank body includes a tank mouth and a tank bottom. The tank body is provided with a main blade, and the vertical height of the tank mouth is higher than the vertical height of the tank bottom. The main blade is provided with a drainage hole for muddy water to flow from the tank mouth to the tank bottom. The tank bottom is provided with a drainage pipe for discharging muddy water out of the tank body. The drainage pipe is provided with a plugging piece for opening and closing the drainage pipe, which can discharge the muddy water remaining in the tank body to prevent the muddy water remaining in the tank body from freezing into ice, thereby ensuring the normal use of the mixing tank. However, due to the small structure of the drainage hole, the residual slurry in the mixing tank cannot be effectively discharged, and no drainage guide channel is provided. Summary of the invention

DETAILED DESCRIPTION

[0029] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0030] The present invention is used to overcome the defects of the above-mentioned prior art and provides an easy-to-drain concrete mixing drum, which can discharge sewage and concrete to a designated location while cleaning. It is easy to operate, has a fast cleaning speed and a high cleaning degree. No residual sewage is accumulated in the drum after cleaning, and has great practical value.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1-6As shown, an easy-to-drain concrete mixing drum is provided, including a drum body 1. The preferred drum body 1 is generally in a straight cylindrical structure and is an integrated structure, provided with a feed port and a drain port. The feed port in this embodiment is the discharge port. If the rotation space of the mixing drum in an actual project is too small to discharge materials from the feed port, an additional discharge port needs to be provided on the curved drum body. The bottom of the drum body 1 is provided with a drain port, a bottom plate 2 for blocking the drain port, and a flexible drainage channel. The preferred drain port can be a circular or square structure, and the bottom plate 2 is a structure adapted to the shape of the drain port. The bottom plate 2 is sealed on the outside of the drain port and one end of the bottom plate 2 is hinged on the outer wall of the drum body 1 so that the bottom plate 2 can be placed on the bottom wall of the drum body 1 during drainage. The drain outlet is opened or closed by rotating around the hinged position. The preferred hinged device is a hinge 2, etc. The flexible drainage channel includes a water inlet, a part of the edge of the water inlet is connected to the free end of the bottom plate 2, and the other part is fixed on the outer wall of the cylinder body 1 at a position where the free end fits. When the bottom plate 2 is opened for drainage, the free end of the bottom plate 2 is flipped outward and the water inlet is stretched open. The stretched water inlet is sleeved on the drain outlet, thereby quickly forming a channel for discharging sewage in the mixing drum to avoid directly scattering sewage on the ground. The edges of the water inlet fixed on the outer wall of the cylinder body 1 and the bottom plate 2 are preferably wider than the drain outlet to ensure that the sewage can completely enter the flexible drainage channel.

[0033] In order to facilitate the installation of the flexible channel 3, connecting rods are provided at the positions for connecting the edge of the water inlet on the free end and the outer wall of the barrel body 1. The connecting rod on the outer wall of the barrel body is a first connecting rod 15, and the connecting rod on the free end is a second connecting rod 21. At the same time, connecting rod fixing devices 16 for fixing the connecting rods are respectively provided on the outer wall of the barrel body and the outer wall of the free end. The edge of the water inlet is suspended on each connecting rod together. Preferably, a plurality of hooks for hanging on the connecting rods are provided on the edge of the water inlet, so that the flexible channel 3 can be quickly hung on the connecting rods. At the same time, the length of the connecting rod must also be wider than the width of the drain outlet, so that there is no need to confirm the optimization of the position of the water inlet edge and the drain outlet, that is, there is no need to measure the relationship between the width of the water inlet edge and the width of the drain outlet. The water inlet edge is directly hung on the entire connecting rod by using the hook, and fastened to the connecting rod in turn, so that the technical effect of the water inlet edge being wider than the drain outlet width can be directly achieved.

[0034] In order to ensure that the water inlet is sleeved on the drain outlet and can effectively avoid being easily broken, the edge of the water inlet includes two connecting parts respectively combined with the connecting rods, and folding parts respectively located between the head ends and the tail ends of the two connecting parts. Then, during the process of flipping and opening the bottom plate 2, the folding part can extend along the opening direction, thereby expanding the edge of the water inlet so that it can be sleeved on the drain outlet. Preferably, the entire flexible drainage channel has elastic characteristics, so that the edge of the water inlet can be fully enlarged during the process of opening the bottom plate 2.

[0035] As a preferred embodiment of the present invention, the connecting rod can be an arc-shaped or semi-frame structure that is compatible with the drain outlet, and then when the bottom plate 2 is opened, the water inlet is directly formed into a shape that is compatible with the drain outlet, or the connecting rod is a straight rod structure. At the same time, the flexible drainage channel includes a water outlet, and a water outlet pipe 31 is sleeved on the water outlet. The water outlet pipe 31 is made of a hard material, and the water outlet pipe 31 includes two symmetrically arranged arc-shaped pipe walls. The water inlet ends of the two arc-shaped pipe walls are hinged, and the axis of the hinge is parallel to the straight rod structure.

[0036] The bottom plate 2 is sealed to the drain outlet to ensure that after the bottom plate 2 covers the drain outlet, water does not flow out from the edge of the bottom plate 2. Preferably, the bottom plate 2 is provided with a raised structure penetrating through the drain outlet, and a flexible waterproof pad 22 is sleeved between the raised structure and the edge of the drain outlet. The flexible waterproof pad 22 is an annular structure and is then sleeved on the outer wall of the raised structure.

[0037] As a preferred embodiment of the present invention, the edge of the drain outlet protrudes outward and forms an annular edge that matches the protruding structure. The width of the annular edge is the same as the axial length of the barrel body 1, which is equivalent to opening the bottom of the mixing drum as a whole. During the drainage process, the drainage path is effectively increased, ensuring the rapid discharge of sewage and preventing the mixing drum from rusting a lot.

[0038] The outer side of the barrel body 1 is provided with a support bracket 6, and the axis of the barrel body 1 is penetrated by a stirring shaft 5, and the two ends of the stirring shaft 5 extend out of the two side walls of the barrel body 1 and are rotatably connected to the bracket 6. A first groove 12 and a second groove 13 are respectively opened on the outer surface of each side wall, and a support rod that can be respectively clamped in the first groove 12 and the second groove 13 is fixed on the bracket 6. The first groove 12 and the axis of the barrel body 1 are respectively at the same distance as the feed port of the barrel body 1, and the second groove 13 is close to the feed port. Placing the support rod in the first groove 12 can fix the barrel and put the mixing barrel in a vertical position to prevent the barrel from rotating during stirring; placing the support rod in the second groove 13 can fix the barrel and facilitate discharging. A plurality of quick tighteners 4 are provided between the free end and the outer wall of the barrel body 1. Preferably, the quick tightener 4 is arranged at the free end, and a tightener bracket 614 adapted to the quick tightener 4 is provided on the outer wall of the barrel body 1.

[0039] Adaptive changes made according to actual needs are all within the protection scope of the present invention.

[0040] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
