[0027] The present invention will now be further described. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0028] As shown in the figure, a mobile dock grab bucket hoisting hopper of the present invention includes a first receiving hopper 5, a second receiving hopper 6, and a third receiving hopper 8 arranged in sequence. The second receiving hopper 6 and the third receiving hopper 8 are connected by a dust suppression grid 7. The dust suppression grid 7 includes a fixed flow plate 15 fixed on the third receiving hopper 8 and a movable flow plate 16 connected to the third receiving hopper through a rotating shaft 17. The fixed flow plate 15 is inclined, and one end of the movable flow plate 16 is connected to the rotating shaft, while the other end can contact the fixed flow plate 15.

[0029] During use, the movable flow plate 16 will rotate due to gravity. At this time, the material will fall into the third receiving hopper 8. The movable flow plate 16 will automatically return to close. Dust will fall into the third receiving hopper 8 with the material and will not easily pass through the dust suppression grid 7 and return to the second receiving hopper 6 to overflow to the outside. In this way, the dust is suppressed in the third receiving hopper 8.

[0030] Furthermore, a suction nozzle 10 is provided at the first receiving hopper 5, and the suction nozzle 10 is connected to a suction device 13 via an air duct 11. Furthermore, there are two, four, or eight suction nozzles 10.

[0031] Furthermore, the first receiving hopper 5 is composed of a first flow plate 51, and the second receiving hopper 6 is composed of a second flow plate 61. The first flow plate 51 and the second flow plate 61 form an annular first air chamber 18, and the suction nozzle 10 is located in the cavity 18. Due to gravity, the material falls from the first receiving hopper 5 into the second receiving hopper 6. The dust raised when the material falls is sucked away by the air duct 11 through the first air chamber 18 and filtered in the dust collector; this also prevents the material from clogging the suction port. Each air duct 11 is equipped with an air duct valve 12, which can individually control the airflow of each suction nozzle.

[0032] Furthermore, a suction nozzle baffle 101 is provided inside the suction nozzle 10. The suction nozzle baffle 101 improves the airflow within the suction nozzle 10, adjusts the airflow drawn in by the suction nozzle 10, and thus adjusts the suction nozzle 10's effectiveness in drawing in dust. Figure 6 As shown, the suction nozzle partition 101 is a hollow partition.

[0033] Furthermore, a discharge port 9 is provided below the third receiving hopper 8, and a suction pipe 19 is provided at the discharge port 9, which is connected to the suction device 13. The material discharge port 9 can be an electric or manual gate, a spiral auger, or have the following structure:

[0034] The discharge port 9 includes a main body 91 connected to the third receiving hopper. A baffle 20 is provided around the main body 91, forming a second air chamber 21 between the baffle 20 and the main body 91. The suction pipe 19 is provided at the baffle.

[0035] The second air chamber 21 is formed by welding or bolting steel plates to the side wall of the material discharge pipe at a certain angle around the outside of the material discharge pipe, thus forming a closed cavity; multiple suction pipes 19 can be provided.

[0036] A gate 22 is provided at the discharge port 9, and the flow rate can be adjusted by the gate 22.

[0037] The suction duct 19 and suction device 13 can effectively collect dust at the discharge port 9, thereby suppressing the escape of dust from the bulk material and improving the working environment.

[0038] This is equivalent to surrounding the discharge port 9 with an air chamber, creating a double-layered discharge port 9 with a partition. The inner layer is for material discharge, and the outer layer is for dust suppression and suction. Utilizing the principle of wind pressure, dust at the discharge port is sucked away, thereby improving the surrounding working environment. Figure 8 As shown in the diagram, the direction of the arrows indicates the direction of dust movement.

[0039] A dust-proof curtain 23 is installed at the discharge port 9. The dust-proof curtain 23 can prevent dust from escaping.

[0040] Furthermore, multiple fixed flow plates 15, movable flow plates 16, and rotating shafts 17 are provided. The fixed flow plate 15 has a bent portion 151 that blocks the rotating shaft 17, ensuring that the material will not fall off the rotating shaft 17 during the falling process.

[0041] Furthermore, it also includes a frame 1 that supports the first receiving hopper 5, the second receiving hopper 6 and the third receiving hopper 8. The bottom of the frame 1 is provided with steering wheels 2 and straight wheels 4 to facilitate the movement of the hoppers as a whole. At the same time, a support for the air duct 11 is also provided at the frame 1.

[0042] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
