It should be noted that the driving device provided in the present application may be provided with a single-head motor 810 only at one end of the driving shaft 300, or may be driven by a double-head motor 810, which does not affect the use of the striker 400 for shielding the sealing member 700.

The sealing member 700 described in the present application may be any type of commercially available sealing member 700, and the type of the sealing member 700 is not the subject matter of the present application, and does not affect the technical effect of the present application. Alternatively, the seal 700 used in this embodiment is a commercially available floating seal, as shown in fig. 2 or fig. 3, and includes two floating seal steel rings side by side and two rubber rings sleeved outside the floating seal steel rings.

Illustratively, referring to fig. 1, fig. 2 and fig. 3, the material stop mechanism 400 includes a material stop sleeve 500 and a material dropping seat 600.

The material blocking sleeve 500 is sleeved outside the driving shaft 300, a sealing cover 530 is arranged at one end of the material blocking sleeve, the sealing cover 530 and the motor seat 800 form a cavity for accommodating the sealing element 700, the size of the cavity is matched with that of the sealing element 700, and the rubber ring of the sealing element 700 abuts against the inner wall of the cavity to be supported, referring to fig. 2, one rubber ring abuts against one side of the motor seat 800, and the other rubber ring abuts against one side of the sealing cover 530. As shown in fig. 2, a sealing cap 530 is integrally formed at one end of the striker sleeve 500.

The material blocking sleeve 500 is further provided with a material blocking portion 510, the material blocking portion 510 is located on a side of the sealing cover 530 far away from the sealing member 700, and on a cross section of the driving shaft 300 (i.e. a plane perpendicular to an axial direction of the driving shaft 300), a projection of the sealing cover 530 falls within a projection range of the material blocking portion 510.

The material blocking sleeve 500 is connected with the driving shaft 300 and synchronously rotates.

The material leaking seat 600 is sleeved outside the material blocking sleeve 500 and fixed between the motor seat 800 and the driving frame 100. Exemplarily, referring to fig. 1 and fig. 3, a raised circular truncated cone is disposed on the periphery of the motor seat 800, the driving frame 100 is provided with a mounting hole 110, a first fixing portion 610 and a second fixing portion 620 are respectively disposed at two ends of the periphery of the material leaking seat 600, and the first fixing portion 610 and the second fixing portion 620 may be raised circular truncated cones or a plurality of lugs uniformly distributed along the circumference. The driving shaft 300 passes through the mounting hole 110 of the driving frame 100, so that the first fixing portion 610 of the material leaking seat 600 is connected with the driving frame 100, the second fixing portion 620 is connected with the circular table of the motor seat 800, the connection mode may be fixed connection, detachable fixed connection, such as bolt connection or welding, and the motor seat 800 and the material leaking seat 600 may also be integrally formed.

The middle part of the material leakage seat 600 is provided with an accommodating cavity 630 for avoiding the material blocking part 510, and under the condition that the material leakage seat 600, the driving frame 100 and the motor seat 800 are connected and the driving shaft 300 and the material blocking sleeve 500 are connected, a small gap exists between the accommodating cavity 630 and the material blocking part 510 to allow the material blocking sleeve 500 to rotate inside the accommodating cavity 630.

As shown in fig. 4, 5 and 6, the striker portion 510 of the striker sleeve 500 divides the accommodating chamber 630 into a first chamber 631 and a second chamber 632 which are juxtaposed in the axial direction of the driving shaft, wherein the sealing cover 530 is located in the second chamber 632. Since the material may pass through the gap between the material stopping sleeve 500 and the material leaking seat 600 (i.e. the gap formed along the outer circumference of the material stopping sleeve 500), the first chamber 631 serves as an isolation space to reduce the material from entering the second chamber. The first chamber 631 lengthens the distance that the material axially crosses the material blocking part 510, the material can move in the first chamber 631, and is not easy to directly cross the material blocking part 510 to contact the sealing cover 530, and is not easy to cross the sealing cover 530 to contact the sealing member 700, so that the effect of preventing the sealing member 700 from being worn is further improved.

Optionally, the sidewall of the first chamber 631 is opened with a material leakage port 633 communicated with the outside, as shown in fig. 2 and fig. 6. The material entering the first chamber 631 can leak out from the leakage hole 633, the material is prevented from being deposited in the first chamber 631, the amount of the material moving in the first chamber 631 is reduced, the material is further prevented from passing over the material blocking part 510, and the effect of preventing the sealing member 700 from being worn is further improved. Further alternatively, as shown in fig. 2 and fig. 6, the material leakage port 633 extends from the first chamber 631 to the second chamber 632 along the axial direction of the driving shaft 300 until the sealing cover 530 is close to the striker 510, that is, the material leakage port 633 extends from the first chamber 631 to the second chamber 632 and does not exceed the sealing cover 530, and with this arrangement, even if a small amount of material enters the second chamber 632 through the striker 510, the material can be discharged from the material leakage port 633, so that the material is prevented from being deposited in the second chamber 632, and the amount of material deposited in the second chamber 632 is reduced, thereby reducing the situation that the material passes through the sealing cover 530 and causes the abrasion of the sealing member 700. Because the material blocking sleeve 500 and the driving shaft 300 rotate synchronously, the material in the accommodating cavity 630 can be driven to move, the orientation of the material leakage port 633 is not limited uniquely, and the material can be thrown out of the material leakage port 633 under the action of centrifugal force. Optionally, in this embodiment, the material leaking port 633 faces vertically downward.

Optionally, the material leakage port 633 may be provided with an isolation net, wherein the pore size of the isolation net is slightly larger than the particle size of the conveyed material. Therefore, materials in the accommodating cavity 630 can be thrown out from the holes of the separation net under the action of centrifugal force, the probability that the externally splashed materials enter the accommodating cavity 630 from the material leakage port 633 is reduced, the materials in the accommodating cavity 630 are further reduced, and the abrasion resistance is improved.

Referring to fig. 2 and 3, the material blocking portion 510 of the material blocking sleeve 500 is, optionally, an annular flange formed by extending a rim of one end of the material blocking sleeve 500 radially outward. Because the annular flange shields seal cap 530, seal cap 530 is less likely to contact material, which is less likely to contact seal 700 beyond seal cap 530.

Referring to fig. 2, the other end of the striker sleeve 500 is provided with an annular material passing groove 520, that is, the end of the striker sleeve 500 far away from the sealing cover 530 and close to the driving wheel 200, and the material passing groove 520 is located outside the first chamber 631. That is, the material blocking sleeve 500 extends out of the material leaking seat 600, and the material passing groove 520 is arranged at the extended position. When the material is scattered to the driving shaft 300, if the material passes through the gap between the material blocking sleeve 500 and the material leaking seat 600, the material needs to pass through the material passing groove 520, and the side wall of the material passing groove 520 has the effect of blocking the material from entering. Alternatively, as shown in fig. 3 and fig. 6, the material passing groove 520 is an annular groove formed by recessing from the surface of the material blocking sleeve 500 to the axial center. After the material falls into the material passing groove 520, the inner wall of the material passing groove 520 blocks the gap between the material blocking sleeve 500 and the material leakage seat 600, which needs to climb from the bottom of the material passing groove 520 to the position of the gap, so that the material is not easy to enter the gap, and can fall from the material passing groove 520. Optionally, the material passing groove 520 is adjacent to the gap position between the material leaking seat 600 and the material blocking sleeve 500.

Further optionally, the material blocking sleeve 500 extends to the rotation plane of the driving wheel 200 and is fixedly connected with the driving wheel 200. The fixed connection mode can be that the anchor components such as bolt are connected as an organic whole, and can set up the rubber circle at the contact surface and seal, also can be that the material stopping sleeve 500 is directly integrated into one piece with drive wheel 200. Therefore, materials are prevented from entering between the material blocking sleeve 500 and the driving shaft 300, and the driving shaft 300 is better protected.

Above-mentioned stock stop 400, optionally, the stock stop 510 on the stock stop 500 includes a plurality of cyclic annular flanges, and a plurality of cyclic annular flanges separate the holding chamber 630 of hourglass material seat 600 for a plurality of to play the effect of multiple protection, the material is if contact sealing member 700 then need pass a plurality of cavities, has further improved the protective effect. Alternatively, the leakage port 633 is an opening that spans multiple chambers simultaneously.

Optionally, the material blocking mechanism 400 may also be a cover body integrally covered outside the motor base 800, the cover body is connected between the motor base 800 and the driving frame 100, and the connection portion is sealed.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
