[0003] Announcement No. CN220371094U discloses a polishing machine discharge adjustment device, including a discharge hopper, a baffle assembly, and an adjustment assembly. The baffle assembly includes a baffle and a rotating shaft. The rotating shaft is rotatably connected to the discharge hopper, and the baffle is detachably connected to the rotating shaft. The baffle is rotatably built into the discharge hopper; the adjustment assembly includes a driving member and an electromagnetic clutch. The electromagnetic clutch has an input shaft and an output shaft. The output shaft of the electromagnetic clutch is connected to the rotating shaft, and the input shaft of the electromagnetic clutch is connected to the output shaft of the driving member, for transmitting the torque output by the driving member to the baffle, and the torque transmitted by the electromagnetic clutch is adjustable. The input shaft of the rotating shaft and the electromagnetic clutch is coaxial with the output shaft of the driving member; the interior of the shell is hollow and one side is open, and the shell is also provided with a first mounting hole and a second mounting hole connected to the interior thereof, and the cover plate is arranged relative to the open end of the shell and can be detachably connected to the shell, the electromagnetic clutch is built into the shell, and the output shaft of the electromagnetic clutch extends toward the outside of the shell through the first mounting hole, and the output shaft of the driving member extends toward the inside of the shell through the second mounting hole; when it is necessary to realize the connection between the rotating shaft, the sleeve and the baffle, the bolt is passed through the fourth through hole, the third through hole and the second through hole, and the nut is connected to the threaded end of the bolt, so that the connection between the rotating shaft, the sleeve and the baffle can be realized, and the rotating shaft, the sleeve and the baffle are connected by bolts and nuts.

[0004] The above-mentioned discharging device has the following defects: (1) Since the discharging adjustment device is generally located at the end of the rice polisher, in the above-mentioned discharging adjustment device, the rotating shaft, the input shaft of the electromagnetic clutch and the output shaft of the driving member are coaxially arranged, which increases the width occupied by the adjustment device. As a result, when installing, the driving member extends out of the rice polisher in the width direction, increasing the area occupied by the installation of the rice polisher, and the extended driving member will hinder the passage of the staff: (2) The electromagnetic clutch is built into the shell, and the output shaft of the electromagnetic clutch extends to the outside of the shell through the first mounting hole. When installing the electromagnetic clutch, it is necessary to first build the output shaft and the shell of the electromagnetic clutch into the shell, and after the electromagnetic clutch slides to the set position, the output shaft of the electromagnetic clutch is The shaft passes through the housing through the first mounting hole, and the output shaft of the electromagnetic clutch needs to pass through the first mounting hole within a limited space, which makes the installation of the electromagnetic clutch inconvenient; (3) The baffle is set in the lower hopper and contacts the sliding rice, which will cause wear and tear and need to be replaced regularly.

[0041] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0042] like Figure 2 and Figure 3 As shown, the utility model provides a polishing machine discharge adjustment device, including a discharge hopper 1, an adjustment component 2 and a drive component 3, the adjustment component 2 includes a rotating shaft 21 and a baffle 22, the rotating shaft 21 is rotatably connected to the discharge hopper 1, and is at least partially built in the discharge hopper 1, the baffle 22 is rotatably built in the discharge hopper 1, and is connected to the rotating shaft 21; the drive component 3 includes a clutch 31 and a drive member 32, the clutch 31 has a power input shaft and an output shaft, the output shaft of the clutch 31 is connected to the rotating shaft 21, and the output torque of the clutch 31 is adjustable, the drive member 32 is connected to the input shaft of the clutch 31, and is used to output torque to the rotating shaft 21 via the clutch 31.

[0043] When it is necessary to adjust the discharge speed of the discharge hopper 1, the driving member 32 is started, and the driving member 32 transmits power to the clutch 31. The clutch 31 outputs a set torque and transmits the torque to the rotating shaft 21 and the baffle 22 to drive the rotating shaft 21 and the baffle 22 to rotate, so that the baffle 22 abuts against the falling material. When the torque of the baffle 22 and the falling material are balanced, the discharge speed of the discharge hopper 1 is constant, and the baffle 22 stops rotating. At this time, the output shaft of the clutch 31 slips relative to the input shaft; when it is necessary to adjust the discharge speed of the discharge hopper 1, the output torque of the clutch 31 is adjusted, thereby adjusting the torque transmitted to the baffle 22 by the clutch 31, so that the baffle 22 rotates relative to the discharge hopper 1, thereby realizing the adjustment of the discharge speed of the discharge hopper 1; there is no need to manually adjust the discharge speed of the discharge hopper 1.

[0044] It should be understood that the discharge hopper 1 can be a tube with a hollow interior and openings at both ends, or a slide with a concave cross-section.

[0045] It should be understood that the clutch 31 can be an electromagnetic powder clutch 31 or a magnetic powder clutch 31, and its working principle is to utilize the magnetization characteristics of magnetic powder in a magnetic field to convert the input current signal into a torque output. The torque of the magnetic powder clutch 31 is basically linearly related to the excitation current, so the output torque can be controlled by changing the magnitude of the excitation current, and the magnitude of the current output to the clutch 31 can be remotely controlled through the equipment, so that the adjustment of the polishing machine discharge can be remotely automated.

[0046] It should be understood that the driving member 32 may be an electric motor, a hydraulic motor, or the like.

[0047] In one embodiment, Figure 1 ,3 As shown in FIG. 5 , the baffle 22 is detachably connected to the rotating shaft 21 .

[0048] When the rotating shaft 21 and the baffle 22 need to be installed on the discharge hopper 1, the rotating shaft 21 is rotatably inserted into the discharge hopper 1, and then the baffle 22 is built into the discharge hopper 1, and the baffle 22 is connected to the rotating shaft 21. At this time, the connection between the rotating shaft 21 and the baffle 22 and the discharge hopper 1 is realized, so that the rotating shaft 21, the baffle 22 and the discharge hopper 1 can be processed and formed separately, and then assembled into one body for easy installation.

[0049] It should be understood that the baffle 22 and the rotating shaft 21 can be detachably connected by screws, bolts, buckles, etc.

[0050] In one embodiment, Figure 1 , 3 As shown in FIG. 5 , the adjustment assembly 2 further includes a rotating sleeve 23 , which is sleeved on the rotating shaft 21 and detachably connected to the rotating shaft 21 ; the baffle 22 is connected to the rotating sleeve 23 , and is connected to the rotating shaft 21 via the rotating sleeve 23 .

[0051] When the baffle 22 needs to be connected to the rotating shaft 21, the rotating sleeve 23 and the baffle 22 are built into the discharge hopper 1, and then the rotating shaft 21 is rotatably inserted into the discharge hopper 1, and the rotating shaft 21 passes through the rotating sleeve 23, and then the rotating sleeve 23 and the rotating shaft 21 are connected.

[0052] In one embodiment, Figure 1 , 3 As shown in FIG. 5 , the adjustment assembly 2 further includes a cushion block 24 , which is connected to the rotating sleeve 23 ; the baffle plate 22 is in surface contact with the cushion block 24 and is detachably connected to the cushion block 24 , and the baffle plate 22 is connected to the rotating sleeve 23 via the cushion block 24 .

[0053] When the baffle 22 is detachably connected to the cushion block 24, the baffle 22 and the cushion block 24 are in surface contact with each other, and the contact area is large, so that the baffle 22 can be firmly fixed to the cushion block 24, and the cushion block 24 is fixedly connected to the rotating sleeve 23; the cushion block 24 and the rotating sleeve 23 can be connected by welding, bolting, etc.

[0054] It should be understood that the pad 24 and the baffle 22 can be detachably connected by bolts, screws and buckles.

[0055] In one embodiment, Figure 1 and Figure 3 As shown, the adjustment assembly 2 further includes a fixing rod 25 , which is connected to the rotating shaft 21 and is arranged along the radial direction of the rotating shaft 21 .

[0056] By setting the fixed rod 25, the fixed rod 25 can display the rotation angle of the rotating shaft 21, and by setting a weight on the fixed rod 25, the counterweight of the weight and the torque output by the clutch 31 act together on the baffle 22 to adjust the discharge speed of the discharge hopper 1.

[0057] In one embodiment, Figure 3 and Figure 4 As shown, the driving assembly 3 further includes a universal joint 33 , and the output shaft of the clutch 31 is connected to the rotating shaft 21 via the universal joint 33 .

[0058] By providing the universal joint 33, power can be transmitted from the output shaft of the clutch 31 to the universal joint 33; moreover, the existence of the universal joint 33 can ensure normal power transmission when there is a deviation between the output shaft of the clutch 31 and the rotating shaft 21 during installation, and can reduce the installation requirements of the clutch 31 and the rotating shaft 21.

[0059] In one embodiment, Figure 3 and 4 As shown, the driving assembly 3 also includes a transmission member 34, which includes a first bevel gear 341 and a second bevel gear 342. The first bevel gear 341 is connected to the output shaft of the driving member 32, and the second bevel gear 342 is connected to the input shaft of the clutch 31, and the second bevel gear 342 is meshed with the first bevel gear 341.

[0060] By setting the first bevel gear 341 and the second bevel gear 342, the power transmission direction of the driving member 32 can be changed, so that the driving member 32 can be set in a direction perpendicular to the output shaft of the clutch 31, which can reduce the width occupied by the discharge adjustment device.

[0061] In one embodiment, Figure 1 and Figure 2 As shown, the driving assembly 3 further includes a cover 35 , and the cover 35 is disposed on the transmission member 34 and the clutch 31 .

[0062] By providing the cover body 35 , the transmission member 34 and the clutch 31 can be covered in the cover body 35 , so as to avoid the transmission member 34 and the clutch 31 being exposed to affect the appearance, and also avoid the potential safety hazard caused by the first bevel gear 341 and the second bevel gear 342 being exposed.

[0063] In one embodiment, Figure 3 and Figure 4 As shown, the driving assembly 3 further includes a positioning frame 36 , the interior of the positioning frame 36 is hollow, the driving member 32 and the clutch 31 are fixed to the positioning frame 36 , and the output shaft of the driving member 32 and the input shaft of the clutch 31 extend into the positioning frame 36 .

[0064] Since the meshing of the first bevel gear 341 and the second bevel gear 342 requires installation accuracy, the cover body 35 is generally produced by sheet metal with low accuracy. If the driving member 32 and the clutch 31 are installed on the cover body 35, the meshing between the first bevel gear 341 and the second bevel gear 342 will be affected. In this embodiment, a positioning frame 36 is provided to fix the driving member 32 and the clutch 31 that require positioning on the positioning frame 36, and the driving member 32 and the clutch 31 are positioned by the positioning frame 36, so that the first bevel gear 341 and the second bevel gear 342 can mesh with each other according to a preset accuracy.

[0065] It should be understood that the positioning frame 36 can be fixed to the cover body 35 or to the body of the polishing machine.

[0066] In one embodiment, Figure 2 As shown, one side of the cover body 35 is open, and the cover body 35 is provided with a fixing hole and a notch 35a relative to the output shaft of the clutch 31. The notch 35a passes through the open side of the cover body 35 and is connected to the fixing hole.

[0067] In this embodiment, the clutch 31 is connected to the cover 35 , and the connection between the clutch 31 and the cover 35 only serves to assist in supporting the cover 35 , the positioning frame 36 , the transmission member 34 and the driving member 32 , and does not affect the installation accuracy of the transmission member 34 .

[0068] It should be understood that the open side of the cover 35 is fixed to the body of the polishing machine. When it is necessary to connect the clutch 31 and the cover 35, the output shaft of the clutch 31 is inserted into the fixing hole through the notch 35a so that the clutch 31 can enter the cover 35, and then the housing of the clutch 31 is connected to the cover 35.

[0069] In one embodiment, Figure 1 As shown in the figure, the cover body 35 is provided with a through hole relative to the driving member 32 .

[0070] When the driving member 32 is installed on the positioning frame 36, the output end of the driving member 32 is passed through the through hole, and the shell of the driving member 32 is fixed to the positioning frame 36, and then the output shaft of the driving member 32 is inserted into the positioning frame 36 through the hole on the positioning frame 36, so that the output shaft of the driving member 32 can be connected to the first bevel gear 341.

[0071] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
