[0016] Figure 2 It is a side view of the utility model.
[0017] Figure 3 It is a top view of the utility model. DETAILED DESCRIPTION
[0018] Reference Figures 1 to 3As shown, a concrete distribution device includes a distribution hopper 1 and a moving mechanism that can drive the distribution hopper 1 to move. The distribution hopper 1 has a feed port 111 on the top and a discharge port 112 on the bottom. The distribution hopper 1 is arranged at the lower end of the moving mechanism so as to be movable and retractable. The moving mechanism is a truss crane. The truss crane is a publicly available prior art and will not be described in detail here. The distribution hopper 1 has a main body 11 and four supporting legs 12. The main body 11 has two side plates located at the left and right ends and two discharge plates located at the front and rear ends. The two discharge plates connect the two side plates and partially extend downwardly. The connection between the two discharge plates and the bottom of the side plates is opened to form the above-mentioned discharge port 112. The four supporting legs 12 are arranged at the connection between the above-mentioned two side plates and the two discharge plates and extend vertically downward. When the distribution hopper 1 needs to be placed on the ground, the four supporting legs 12 are used to support the main body 11.
[0019] A guide mechanism is provided between the fabric hopper 1 and the moving mechanism, and is arranged so that when the fabric hopper 1 rises to be close to the moving mechanism, the guide mechanism can guide the fabric hopper 1 to rise stably to the bottom of the moving mechanism, and the guide mechanism includes at least two guide rods 2 and at least two sleeves. In this embodiment, three guide rods 2 are used in combination with three sleeves. The guide rod 2 is fixedly arranged at the upper end of the fabric hopper 1, and the sleeve is fixedly arranged at the lower end of the moving mechanism. When the fabric hopper 1 rises to be close to the moving mechanism, the guide rod 2 is inserted into the sleeve. After the guide rod 2 is inserted into the sleeve, the moving trajectory of the fabric hopper 1 can be limited. The three guide rods 2 inserted into the three sleeves can limit the shaking of the fabric hopper 1 with respect to the large displacement of the moving mechanism, and can also prevent the fabric hopper 1 from rotating relative to the moving mechanism to a certain extent.
[0020] Usually, when the distribution hopper 1 rises to the bottom of the moving mechanism, a rigid collision is likely to occur, causing the distribution hopper 1 to shake, and when the moving mechanism drives the distribution hopper 1 to move, it will swing due to inertia, which may easily cause the workers to hit or the concrete to spill, posing a high safety hazard. However, under the action of the guiding mechanism, the distribution hopper 1 will not shake with a large displacement during the rising process, will not throw nearby workers, and the concrete in the distribution hopper 1 will not spill.
[0021] A stirring shaft 51 is provided in the distribution hopper 1, and a stirring blade 52 is provided on the stirring shaft 51. A driving motor 53 for driving the stirring shaft 51 to rotate is provided on the distribution hopper 1. The driving motor 53 drives the stirring shaft 51 to rotate, so that the stirring blade 52 can stir the concrete in the distribution hopper 1 to make the concrete more uniform.
[0022] It also includes a control device, the mobile mechanism is connected to the control device, the control device includes a remote control and a cruise sensor 3 arranged on the material distribution hopper 1, the cruise sensor 3 receives the command issued by the remote control, controls the mobile mechanism to drive the material distribution hopper 1 to move to the target position, so that the staff can control the automatic cruise of the material distribution hopper 1 by operating the remote control with one key, which is convenient to operate and moves accurately. The control device also includes a plurality of safety sensors 4, which are respectively arranged on a plurality of supporting feet 12. The safety sensors 4 are used to monitor people or obstacles approaching the material distribution hopper 1 during the movement of the material distribution hopper 1, thereby issuing an alarm or powering off. The safety sensors 4 are arranged on a plurality of supporting feet 12 to achieve the effect of multi-directional sensing, further improving safety. A vibrator (not shown in the attached figure) is arranged on the body 11 of the material distribution hopper 1, and the vibrator can prevent concrete from solidifying on the inner wall of the material distribution hopper 1.
[0023] It also includes a bottom cover (not shown in the drawings) which is movably arranged at the bottom of the material distribution hopper 1 and can cover the discharge port 112. The bottom cover is connected to the control device and can be controlled by a remote control to change the size of the discharge port 112. By controlling the size of the discharge port 112, the amount of material discharged can be controlled to achieve fine distribution.
