[0002] Concrete is a commonly used building material, which is mixed with cement, sand, aggregate and water in a certain proportion. Concrete mixer is needed in concrete processing. Various raw materials of concrete are mixed and stirred by concrete mixer. The mixer mixes the raw materials thoroughly by rotating the mixing barrel to ensure that the concrete has uniform texture and appropriate strength. Concrete mixer is widely used in construction sites, road construction, bridge engineering and water conservancy engineering.

[0003] At present, when concrete mixers on the market are used, they are directly fed by turning the upper hopper through a hydraulic rod. When the existing concrete mixers are fed, the materials are poured from the outlet of the upper hopper into the interior of the mixing tank, which will generate a certain amount of dust, and the dust will splash outward. Therefore, we propose improvements to the existing concrete mixers with hydraulic feeding. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the accompanying drawings and specific embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 4 The concrete mixer with hydraulic feeding described in the utility model comprises a mixer frame 1, a mixing tank 3 and a hopper 8. A mounting frame 2 is arranged above the mixer frame 1, and a mixing tank 3 is installed on the inner side of the mounting frame 2. A water tank 4 is arranged above one side of the mixing tank 3, and the water tank 4 is installed above the mixer frame 1 through a supporting frame 5. A connecting arm 6 is installed on the outer side of the mixer frame 1 close to the supporting frame 5, and a hydraulic rod 7 is movably installed on the outer side below the connecting arm 6. The output end of the hydraulic rod 7 is equipped with a hopper 8 through a rotating shaft, and the upper part of the hopper 8 is connected to the connecting arm 6, and a feeding port 9 is opened above the hopper 8.

[0021] A mounting seat 10 is provided at the upper end edge of the upper hopper 8, and a baffle plate 11 is inserted and docked inside the mounting seat 10, and a limiting groove 12 is provided on one side of the baffle plate 11; a connecting seat 13 is provided on the side of the upper hopper 8 close to the mounting seat 10, and a connecting rod 14 is passed through the middle of the connecting seat 13, a connecting strip 15 is provided inside the connecting rod 14, and a limiting plug block 16 is connected to the side of the connecting strip 15 away from the connecting rod 14; the limiting plug block 16 passes through the mounting seat 10 and docks with the limiting groove 12, a spring 17 is sleeved and installed on the outer side of the connecting rod 14, and the two ends of the spring 17 are respectively connected to the connecting strip 15 and the connecting seat 13, the limiting plug block 16 is plug-connected with the limiting groove 12, the limiting plug blocks 16 are evenly spaced, and the connecting strip 15 forms a telescopic structure with the connecting seat 13 through the spring 17.

[0022] During the specific implementation, the connecting rod 14 is first pulled outward to drive the connecting strip 15 and the limit plug 16 to move synchronously, and the moving connecting strip 15 squeezes the spring 17 sleeved on the outside of the connecting rod 14 until the connecting rod 14 is pulled to the limit position. At this time, the limit plug 16 and the mounting seat 10 are separated, and the shielding plate 11 can be docked and inserted into the inside of the mounting seat 10, and then the pulled connecting rod 14 is loosened. The loosened connecting rod 14 can drive the limit plug 16 to automatically reset through the elastic force of the spring 17. When the limiting plug 16 passes through the mounting seat 10 and is connected to the limiting groove 12, the limiting assembly of the shielding plate 11 is completed. When the hydraulic rod 7 is started to drive the upper hopper 8 to flip upward along the connecting arm 6, the shielding plate 11 arranged at the outlet end of the upper hopper 8 can cover the outside of the mixing tank 3. By installing the shielding plate 11 on the upper hopper 8 which can be flipped synchronously with the flipping of the upper hopper 8, the opening of the mixing tank 3 is shielded and protected during loading, thereby preventing the concrete mixer with hydraulic loading from splashing dust during loading.

[0023] See also Figure 1 and Figure 5 , support legs 19 are provided at the edge corners of the mixer frame 1, and a fixed seat 20 is provided at the bottom of the mixer frame 1, and an abutment plate 21 is provided between the two fixed seats 20; docking seats 22 are connected above both ends of the abutment plate 21, and one end of the docking seat 22 is docked and inserted in the interior of the fixed seat 20, and a guide rod 23 passes through the middle of one end of the docking seat 22; a connecting plate 24 is provided above the inner walls of the two docking seats 22, and a motor 25 is installed below the mixer frame 1, a threaded rod 26 is connected to the output end of the motor 25, and the threaded rod 26 passes through the middle of the connecting plate 24, the threaded rod 26 is threadedly connected to the connecting plate 24, and the docking seats 22 are symmetrically distributed about the center line of the abutment plate 21.

[0024] During specific implementation, the concrete mixer is pushed to the designated use position, and the threaded rod 26 connected to the output end is driven to rotate synchronously by starting the motor 25. Since the threaded rod 26 and the abutment plate 21 are threadedly connected, the outer abutment plate 21 can be moved downward as the threaded rod 26 rotates. The movable abutment plate 21 moves downward inside the fixed seat 20 along the guide rod 23 through the docking seats 22 connected at both ends until the abutment plate 21 is moved downward to the limit position. At this time, the bottom of the abutment plate 21 contacts the ground. The abutment plate 21 that can move downward to contact the ground increases the contact area between the mixer frame 1 and the ground, thereby making the concrete mixer more stably placed.

[0025] In summary, when using the concrete mixer with hydraulic loading, first place the concrete mixer at a designated position, then connect the concrete mixer to a power source, and add the concrete raw materials to be mixed from the feeding port 9 to the interior of the upper hopper 8. The hydraulic rod 7 is started to drive the connected upper hopper 8 upward and flip along the connecting arm 6 until the upper hopper 8 tilts and the outlet faces downward. The raw materials in the upper hopper 8 can be poured into the interior of the mixing tank 3, and water can be added to the interior of the mixing tank 3 from the water tank 4 according to actual needs, thereby completing the hydraulic loading operation.
