[0008] In this embodiment of the application, the number of suction pipes is at least two, and the at least two suction pipes are evenly spaced along the circumferential distance of the rotating ring.
[0009] In this embodiment, the suction pipe is tilted upwards in the direction away from the suction space.
[0010] In this embodiment, the main body of the baffle and the two overlapping plates are integrally formed.
[0011] In this embodiment, the drive assembly includes a drive member, a gear, and a gear ring.

[0040] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0041] The hopper device of this application is described below with reference to the accompanying drawings.
[0042] like Figures 1 to 3 As shown, this application provides a hopper device, wherein the hopper device includes a hopper assembly 10, an air suction assembly 20, and a rotating ring mechanism. The hopper assembly 10 forms a dust suction space 15 with a side opening around the feed inlet 14. The air suction assembly 20 is used to supply air into the dust suction space 15. The rotating ring mechanism includes a drive assembly 31, a rotating ring 32, and a dust suction pipe 33. The rotating ring 32 is rotatably disposed in the dust suction space 15 and seals the side opening. The dust suction pipe 33 is disposed on the rotating ring 32, and one end of the dust suction pipe 33 communicates with the dust suction space 15, and the other end is disposed towards the feed inlet 14. The drive assembly 31 is disposed on the hopper assembly 10 for driving the rotating ring 32 to rotate.
[0043] A feed inlet 14 is formed at the upper end of the hopper assembly 10, through which material enters the hopper assembly 10. A side-opening dust collection space 15 is formed around the feed inlet 14. A rotating ring 32 is rotatably disposed within the dust collection space 15 and seals the side opening, preventing dust from overflowing again after entering the dust collection space 15. A dust collection pipe 33 is disposed on the rotating ring 32, with one end connected to the dust collection space 15 and the other end facing the feed inlet 14. The suction assembly 20 draws air into the dust collection space 15, causing dusty air to enter the suction pipe 33. The dusty air then passes through the dust collection space 15 and enters the suction assembly 20, thus purifying the air around the hopper device. Furthermore, the drive component 31 can drive the rotating ring 32 to rotate. The rotating ring 32 is equipped with a suction pipe 33. The rotation of the rotating ring 32 drives the suction pipe 33 to rotate, thereby changing the suction position of the suction pipe 33, so that the suction pipe 33 can suction from different positions, thereby improving the suction effect.
[0044] In the embodiments of this application, please refer to Figure 2 and Figure 3 The rotating ring 32 includes a baffle body 321 and two overlapping plate parts 322. The baffle body 321 is configured to cover the lateral opening. The two overlapping plate parts 322 are arranged at intervals on the side of the baffle body 321 facing the lateral opening. Both overlapping plate parts 322 extend into the suction space 15 and are respectively fitted to the two inner walls of the suction space 15. The suction pipe 33 is provided on the baffle body 321, and the baffle body 321 is drivenly connected to the drive assembly 31.
[0045] The main body 321 of the baffle extends vertically and covers the side opening, so that the rotating ring 32 can seal the side opening. A suction pipe 33 is provided on the main body 321. Two overlapping plates 322 are spaced apart vertically and are located on the side of the main body facing the side opening. Both overlapping plates 322 extend into the suction space 15 and are respectively fitted against the upper and lower inner walls of the suction space 15. The drive assembly 31 is driven to rotate the main body 321, causing the two overlapping plates 322 to rotate relative to the upper and lower inner walls of the suction space 15. By setting two overlapping plates 322 to be respectively attached to the upper and lower inner walls of the suction space 15, the contact area between the rotating ring 32 and the hopper assembly 10 is increased, so that the rotating ring 32 can rotate stably and reliably relative to the inner wall of the suction space 15, thereby improving the stability of the suction pipe 33 rotation.
[0046] In the embodiments of this application, please refer to Figure 2 and Figure 3The end of the baffle body 321 extends out of the overlapping plate 322 to form an overlapping surface 323 that overlaps and fits with the periphery of the lateral opening.
[0047] The upper and lower ends of the baffle body 321 extend out of the two overlapping plate portions 322 respectively, so that an overlapping surface 323 is formed between the baffle body 321 and the overlapping plate portion 322. The overlapping surface 323 overlaps and fits with the periphery of the side opening. By setting the overlapping surface 323, the contact area between the rotating ring 32 and the hopper assembly 10 is further increased, so that the rotating ring 32 can rotate more stably relative to the hopper assembly 10.
[0048] In the embodiments of this application, please refer to Figure 1 The number of suction pipes 33 is at least two, and the at least two suction pipes 33 are evenly spaced along the circumference of the rotating ring 32. By setting the number of suction pipes 33 to at least two, the efficiency of suction pipes 33 in sucking up dusty air is improved. The suction assembly 20 draws air into the suction space 15, so that dusty air enters the suction space 15 from the at least two suction pipes 33, and then enters the suction assembly 20 from the suction space 15, thereby purifying the air around the hopper device. Furthermore, at least two suction pipes 33 are connected to the suction space 15, which connects the suction pipes 33 and the suction assembly 20, allowing the suction assembly 20 to suck up air from multiple suction pipes 33.
[0049] For example, the number of suction tubes 33 can be two, three, or other numbers.
[0050] In the embodiments of this application, please refer to Figure 1 The suction pipe 33 and its rotating ring 32 are tilted upwards in a direction away from the suction space 15. The dust and air will float above the feed inlet 14. The upward tilt of the suction pipe 33 and its rotating ring 32 in a direction away from the suction space 15 can better draw in the dust and air, improving the efficiency of air purification.
[0051] In the embodiments of this application, please refer to Figure 2 and Figure 3 The baffle body 321 and the two overlapping plate parts 322 are integrally formed, which reduces the installation gap between the baffle body 321 and the overlapping plate parts 322, saves the installation steps between the baffle body 321 and the overlapping plate parts 322, and makes the rotating ring 32 more airtight, preventing dust from overflowing again after entering the dust collection space 15.
[0052] In the embodiments of this application, please refer to Figure 1The drive assembly 31 includes a drive member 311, a gear 312 and a gear ring 313. The gear ring 313 and the rotating ring 32 are arranged in the same line and connected to the rotating ring 32. The drive member 311 is disposed on the hopper assembly 10 and is drivenly connected to the gear 312. The gear 312 is meshed with the gear ring 313.
[0053] The gear ring 313 and the rotating ring 32 are collinear in center and connected to each other, allowing them to rotate synchronously. A drive unit 311 is mounted on the hopper assembly 10 and is connected to a gear 312. The drive unit 311 drives the gear 312 to rotate, and the gear 312 meshes with the gear ring 313. The rotation of the gear 312 drives the gear ring 313 to rotate, and the gear ring 313, connected to the rotating ring 32, also drives the rotating ring 32 to rotate, thereby rotating the suction pipe 33. The transmission is achieved through the meshing of the gear 312 and the gear ring 313, resulting in high transmission accuracy and stable transmission.
[0054] In the embodiments of this application, please refer to Figure 1 A connecting rod 314 is provided between the side of the gear ring 313 away from the gear 312 and the rotating ring 32. There are at least two connecting rods 314, and the at least two connecting rods 314 are evenly distributed along the circumference of the gear ring 313.
[0055] A connecting rod 314 is provided on the inner side of the toothed ring 313. The connecting rod 314 is connected to the rotating ring 32. At least two connecting rods 314 are evenly distributed along the circumference of the toothed ring 313, so that the force on the rotating ring 32 is more uniform and the connection between the toothed ring 313 and the rotating ring 32 is more stable and reliable.
[0056] In the embodiments of this application, please refer to Figure 1 The hopper assembly 10 includes a base 11, a hopper body 12, and a sealing ring 13. The base 11 is sleeved on the outside of the hopper body 12, and the sealing ring 13 is connected to the hopper body 12, and the sealing ring 13 forms a dust suction space 15. A support seat 16 is provided on the base 11, and the support seat 16 forms a receiving cavity 17 with an opening facing the toothed ring 313. The receiving cavity 17 is used to receive the driving component 311.
[0057] The base 11 is fitted over the hopper body 12 and is used to mount the hopper. The sealing ring 13 is connected to the hopper body 12 and forms a dust suction space 15. The support 16 forms a receiving cavity 17 with an opening facing the toothed ring 313. The drive member 311 is disposed in the receiving cavity 17. The support 16 is used to mount the drive member 311, which facilitates the drive member 311 to drive the rotating ring 32 to rotate.
[0058] Specifically, the drive component 311 can be a motor, which has the advantages of stable output and high precision.
[0059] In the embodiments of this application, please refer to Figure 1 The support base 16 includes a seat body 162 and a connecting arm 161 connected to each other. The connecting arm 161 is connected to the base 11. The seat body 162 includes a support plate 1621 connected to the connecting arm 161, a protective ring 1622 spaced apart from the support plate 1621, and at least two protective rods 1623 connected between the support plate 1621 and the protective ring 1622. The support plate 1621, the protective ring 1622, and the protective rods 1623 enclose a receiving cavity 17.
[0060] One end of the connecting arm 161 is connected to the base 11, and the other end is connected to the support plate 1621. A protective ring 1622 is spaced apart from the support plate 1621 in the vertical direction, and a protective rod 1623 extends in the vertical direction. The protective ring 1622 and the support plate 1621 are connected by the protective rod 1623. There are at least two protective rods 1623, which are evenly spaced along the circumference of the protective ring 1622, making the connection between the protective ring 1622 and the support plate 1621 more stable and reliable. By setting the protective ring 1622 to protect the driving component 311, the driving component 311 is prevented from falling out of the receiving cavity 17, thus improving the structural stability of the support base 16.
[0061] In the embodiments of this application, please refer to Figure 1 The hopper assembly 10 also includes a support rod 18. One end of the support rod 18 is connected to the side of the sealing ring 13 away from the rotating ring 32, and the other end of the support rod 18 is connected to the base 11. By setting the support rod 18 to connect the sealing ring 13 and the base 11, the sealing ring 13 can be fixed, so that the structure of the hopper assembly 10 can be more stable and reliable.
[0062] In other embodiments, the sealing ring 13 may also be integrally formed with the hopper body 12, saving the installation steps between the sealing ring 13 and the hopper body 12.
