Description

Technical Field

[0001] The utility model relates to the technical field of concrete loading and unloading, in particular to a concrete discharging device. Background Technique

[0002] Concrete truck discharging is one of the important links in the construction process of concrete mixer trucks. When discharging, the engine of the concrete truck is started, and power is transmitted to the mixing tank through transmission devices such as a power take-off, a hydraulic pump, and a speed reducer, so that it starts to rotate. The rotation speed is usually 3 - 14 revolutions per minute. Under the action of the spiral pushing of the blades in the mixing tank, the concrete moves towards the discharging port and is discharged through the discharging hopper. During this process, it is necessary to ensure the uniformity and stability of the discharging operation to avoid the overflow or leakage of concrete.

[0003] Existing concrete discharging generally uses a single discharging hopper. However, sometimes the discharging location is far away and the concrete truck cannot get close, so a longer discharging hopper is needed. The existing structure cannot meet the requirements. Therefore, a concrete discharging device is designed. Content of the Utility Model

The telescopic end of the hydraulic cylinder is rotatably connected to the bottom of the frame. The frame is provided with a first discharging hopper, a second discharging hopper, and a third discharging hopper from top to bottom. The top of the frame is provided with two cross beams one. A cross beam two is slidably inserted into the cross beam one. Through slots are opened on the inner sides of the cross beam one and the cross beam two, and the two slots match each other. Suspension hooks are fixedly connected to both sides of the first discharging hopper, the second discharging hopper, and the third discharging hopper. The suspension hooks are slidably installed in the slots and can be locked in place.

[0006] Preferably, the second discharging hopper is attached to the bottom of the first discharging hopper, the third discharging hopper is attached to the bottom of the second discharging hopper, and the inner walls of all three are arc-shaped.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-5 , a concrete discharging device, including an L - shaped connecting piece 1 fixed to the tail of the vehicle body. The L - shaped connecting piece 1 is rotatably connected to a rotating base 2. The top of the rotating base 2 is rotatably connected to a frame 3, and the bottom is rotatably connected to a hydraulic cylinder 4. The telescopic end of the hydraulic cylinder 4 is rotatably connected to the bottom of the frame 3. The hydraulic cylinder 4 controls the pitching angle of the frame 3. The rotating base 2 controls the left - right rotation of the frame 3.

[0019] Inside the frame 3, there are a top-down first discharge hopper 5, a second discharge hopper 6, and a third discharge hopper 7. The second discharge hopper 6 is attached to the bottom of the first discharge hopper 5, and the third discharge hopper 7 is attached to the bottom of the second discharge hopper 6. The inner walls of all three are arc-shaped. The three discharge hoppers are connected to each other, which can increase the discharge length and send the concrete in the concrete truck to the corresponding location.

[0020] There are two first crossbeams 9 at the top of the frame 3. A second crossbeam 11 is slidably inserted into the first crossbeam 9. Through slots 10 are opened on the inner sides of the first crossbeam 9 and the second crossbeam 11, and the two through slots 10 match each other. Suspension hooks 8 are fixedly connected to both sides of the first discharge hopper 5, the second discharge hopper 6, and the third discharge hopper 7. The suspension hooks 8 are slidably installed in the through slots 10 and can be locked in place.

[0021] Specifically, the suspension hook 8 includes a rod body 81 fixed to the side wall of the discharge hopper. A stud 82 is provided on the side wall of the rod body 81. A locking nut 83 is threadedly sleeved on the stud 82. The stud 82 is inserted into the through slot 10.

[0022] By sliding the suspension hook 8, the discharge hopper can be driven to slide, thereby controlling the positions of the three discharge hoppers. After adjusting the positions of the discharge hoppers, rotate the locking nut 83 so that the locking nut 83 fits against the first crossbeam 9 or the second crossbeam 11 to prevent the discharge hopper from moving.

[0023] The steel material of the frame 3 is of a hollow structure, which reduces the weight of the frame 3.

[0024] Working principle: For a concrete discharge device of the present utility model, during use, the hydraulic cylinder 4 controls the pitching angle of the frame 3. Rotating the base 2 can achieve the left and right rotation of the frame 3. The three discharge hoppers inside the frame 3 can be connected to each other, which can increase the discharge length and send the concrete in the concrete truck to the corresponding location.

[0025] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
