Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0026] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] In the related art, polishing is achieved by frictional vibration of polishing pellets. However, due to the heavy weight of the polishing pellets, collisions of the polishing pellets during the falling process will also cause the rice grains to break.

[0028] In order to solve the problems in the related art to a certain extent, an embodiment of the present application provides a polishing machine. When it is needed, the problem of broken rice caused by collision can be reduced by simply setting the friction ball to be hollow to reduce the weight.

[0029] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0030] Combination Figure 1-Figure 4 The embodiment of the present application provides a polishing machine, including a rotary chamber 1, in which a friction ball 2 is placed, and the friction ball 2 is hollow.

[0031] In some embodiments, the friction ball 2 is embedded with an iron sheet 3, and the outer side of the rotary chamber 1 is provided with an annularly distributed electromagnet 4, which is symmetrically and alternately energized. This arrangement enables the friction ball 2 to move in the rotary chamber 1.

[0032] Specifically, a supporting telescopic sleeve 9 is provided at the bottom end of the rotary chamber 1, one end of the rotary chamber 1 is rotatably connected to a hinge block 10, and the outer surface of the hinge block 10 is rotatably connected to a support frame 11. Through such an arrangement, the rotary chamber 1 can swing, thereby facilitating material discharge.

[0033] Specifically, the feed end of the rotary chamber 1 is provided with an external thread 5, the outer ring of the external thread 5 is threadedly connected with a double-threaded sleeve 6, and barrier sleeves 7 are fixedly installed on both sides of the inside of the double-threaded sleeve 6. A through hole 8 is opened on the surface of the barrier sleeve 7 on one side, and the diameter of the through hole is smaller than the diameter of the friction ball 2. A notch 19 connected to the through hole 8 is opened on the outer ring of the double-threaded sleeve 6. Through such an arrangement, the friction ball 2 can be filtered, thereby achieving the separation of rice and the friction ball 2.

[0034] Specifically, a bevel gear ring 12 is fixedly mounted on the outer ring of the rotary chamber 1, a motor 13 is fixedly mounted on the top of the support frame 11, and a bevel gear 14 meshing with the bevel gear ring 12 is fixedly mounted on the output end of the motor 13. This arrangement enables the rotary chamber 1 to rotate.

[0035] In some embodiments, a fixing frame 15 is fixedly installed on both sides of the rotating chamber 1, a motor 16 is fixedly installed on one side of the fixing frame 15, a winding wheel 17 is fixedly installed on the output end of the motor 16, and a traction belt 18 is fixedly connected to the outer surface of the winding wheel 17. The traction belt 18 is sleeved on the outside of the rotating chamber 1 and fixedly connected to the other end of the fixing frame 15. Through such an arrangement, the rotating chamber 1 can be supported.

[0036] Specifically, there are at least two winding wheels 17, and the two winding wheels 17 are symmetrically arranged. Such an arrangement can ensure the balance of the rotary chamber 1.

[0037] Place rice in the rotary chamber 1, and connect the double-headed threaded sleeve 6 to the rotary chamber 1. Drive the bevel gear ring 12 to rotate through the bevel gear 14, so that the rotary chamber 1 can rotate, so that the rice and the friction ball 2 can rub to achieve polishing. During the polishing process, the electromagnet 4 is alternately energized. Since an iron sheet 3 is provided inside the friction ball 2, the position of the friction ball 2 can be changed. Since the friction ball 2 is hollow, the problem of broken rice caused by the collision of the friction ball 2 can be reduced.

[0038] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0039] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
