[0031] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] Embodiment 1:

[0033] The present embodiment 1 provides a rice milling machine feed anti-blocking structure, which is arranged between the outlet of the feed funnel 2 of the rice milling machine and the inlet of the rice milling bin 1 (see the background technology, the rice milling bin 1 is connected with the feed funnel 2), and can dredge the material (such as rice) in the feed funnel 2 to facilitate the material to flow smoothly into the rice milling bin 1, thereby improving the processing efficiency of the rice milling machine and meeting the production needs.

[0034] Please see attached Figure 1 To Attachment Figure 6 As shown, the rice milling machine feed blocking prevention structure 3 described in this embodiment 1 includes a valve assembly and a dredging member 33, wherein the valve assembly is provided with a valve plate 30 arranged between the inlet of the rice milling bin 1 and the outlet of the feed funnel 2, and a driving member 31 capable of driving the valve plate 30 to move to connect or isolate the feed funnel 2 with the rice milling bin 1; the dredging member 33 is arranged on the valve plate 30 and extends into the feed funnel 2 at the same time, and the dredging member 33 can move with the valve plate 30 to dredge the material in the feed funnel 2.

[0035] From the above, it can be known that the working method of the rice milling machine feed blocking prevention structure 3 in this embodiment 1 is:

[0036] S1: The rice milling machine is initialized, and the driving member 31 drives the valve plate 30 to be in a closed state, that is, the valve plate 30 separates the feed hopper 2 from the rice milling bin 1;

[0037] S2: the rice milling machine starts to work, and the driving member 31 drives the valve plate 30 to be in an open state, that is, the valve plate 30 connects the feed hopper 2 with the rice milling bin 1;

[0038] The material is poured into the feeding funnel 2, and flows through the outlet of the feeding funnel 2 and the inlet of the rice milling bin 1 in sequence, and then flows into the rice milling bin 1; this process can be called the material unloading process.

[0039] In the process of feeding the above-mentioned materials, if the materials are fed smoothly, the valve plate 30 will remain in an open state under the control of the driving member 31; on the contrary, if the materials are not fed smoothly and are blocked, the driving member 31 will drive the valve plate 30 and the dredging member 33 to reciprocate together, so that the dredging member 33 can move and dredge the materials in the feeding funnel 2, thereby facilitating the smooth flow of materials into the rice milling bin 1 and avoiding the blocking of the outlet of the feeding funnel 2 / the inlet of the rice milling bin 1. In short, the anti-blocking structure 3 of the rice milling machine feed in this embodiment 1 has excellent anti-blocking and dredging functions, which can well ensure the smooth feeding of materials and improve the processing efficiency of the rice milling machine.

[0040] The specific structure of the rice milling machine feed blocking prevention structure 3 described in the embodiment 1 is described in detail below.

[0041] First, regarding the clearing piece 33.

[0042] Please continue to refer to the attached Figure 1 , Attachment Figure 4 and attached Figure 6As shown, in this embodiment 1, the dredging member 33 is a rod structure, and is configured to be vertically or obliquely arranged on the valve plate 30 according to processing requirements. By arranging the dredging member 33 on the valve plate 30, there is no need to configure other driving mechanisms to drive the dredging member 33 to move, thereby simplifying the structural configuration and control logic design, facilitating structural installation and electric control operation, and reducing production costs.

[0043] Furthermore, the rod structure may preferably be any one of a straight rod, a spiral rod and an arc rod. Figure 6 The rod structure is shown as a straight rod, but this embodiment 1 is not limited to the straight rod, and other shapes such as a spiral rod or an arc rod can be used according to production requirements.

[0044] In addition, it is explained that: ① When the rod structure adopts a straight rod or a spiral rod, the rod structure is configured to be arranged obliquely on the valve plate 30. The straight rod or spiral rod-shaped dredging member 33 is arranged obliquely, which can show a wider range of movement. ② When the rod structure adopts an arc rod, the rod structure is configured to be arranged vertically or obliquely on the valve plate 30.

[0045] Furthermore, the clearing member 33 is fixedly disposed on the valve plate 30, and the fixing method can be welding or threaded connection.

[0046] Next, regarding the valve assembly.

[0047] In this embodiment 1, the structure of the valve plate 30 being arranged between the inlet of the rice milling bin 1 and the outlet of the feed hopper 2 is as follows: Figure 2 , Attachment Figure 3 , Attachment Figure 5 and attached Figure 6 As shown, the valve assembly is also provided with a valve seat 32 fixedly arranged between the inlet of the rice milling bin 1 and the outlet of the feed funnel 2, and the valve seat 32 is provided with a through hole 320 respectively connected with the inlet of the rice milling bin 1 and the outlet of the feed funnel 2, and a slide groove provided on the opposite inner sides of the through hole 320 and provided for sliding connection with the valve plate 30.

[0048] It can be understood that, ① based on the fact that the valve plate 30 and the driving member 31 in the present embodiment 1 are configured as one, the structure of the through hole 320 is optimally designed as follows: one side of the through hole 320 is open (i.e., an opening), so that the valve plate 30 can be slidably inserted into the through hole 320 through the combination of the above-mentioned opening and the sliding groove; Figure 6FIG. 3 shows a case where the through hole 320 is a U-shaped slot. Thus, when the driving member 31 drives the valve plate 30 to reciprocate, the valve plate 30 can open or close the through hole 320. Figure 6 The valve plate 30 is shown to completely cover / close the through hole 320 .

[0049] ② Based on the installation relationship between the through hole 320 and the valve plate 30, the maximum opening area of ​​the through hole 320 actually opened by the valve plate 30 is smaller than the original opening area of ​​the through hole 320 (which can be understood as: the opening area of ​​the through hole 320 when the valve plate 30 is not installed on the through hole 320), and in order to ensure the safe and smooth discharge of materials, the through hole 320 must be kept in the maximum opening state during the entire discharge process of the materials. For the convenience of the following description, the maximum opening of the through hole 320 actually opened by the valve plate 30 is defined as: the working opening of the through hole 320, and the downward projection of the outlet of the feed funnel 2 must be able to completely fall into the working opening of the through hole 320, and the downward projection of the working opening of the through hole 320 must be able to completely fall into the inlet of the rice milling bin 1.

[0050] ③ Based on the installation method of the valve plate 30, in this embodiment 1, the driving member 31 adopts a linear driving structure, specifically: the driving member 31 preferably adopts a cylinder. Of course, according to production requirements, the driving member 31 can also adopt a structure such as "a combination of a motor and a lead screw module".

[0051] In addition, although the number of the valve plates 30 and the driving members 31 is optimized in this embodiment 1, the number of the clearing members 33 is not limited in this embodiment 1 and is configured specifically according to production requirements.

[0052] In addition, in this embodiment 1, a sensor 36 capable of sensing the displacement information of the valve plate 30 is also provided on the outer side of the rice milling bin 1. The sensor 36 can transmit the displacement information of the valve plate 30 sensed by it to the controller of the rice milling machine. The controller controls the operation of the driving member 31 accordingly according to the received displacement information, thereby improving the feed anti-blocking structure of the rice milling machine, as well as the working accuracy and working efficiency of the rice milling machine.

[0053] Embodiment 2:

[0054] The second embodiment also provides a rice mill feed blocking prevention structure. Compared with the first embodiment, the second embodiment is different in that the way the dredging member 33 is installed on the valve plate 30 is different from that in the first embodiment.

[0055] Specifically, in the present embodiment 2, the clearing member 33 is rotatably disposed on the valve plate 30 .

[0056] For further information, please see the attached Figure 7 As shown, the dredging member 33 in this embodiment 2 is rotatably arranged on the valve plate 30 via a ball bearing 34. By designing the dredging member 33 to be rotatably installed, when the driving member 31 drives the valve plate 30 and the dredging member 33 to move, the dredging member 33 can be rotated under the reverse friction of the material, so that the dredging member 33 can generate a rotational driving force on the material, so that the dredging effect on the material is better.

[0057] In addition, in order to prevent the material from entering the ball bearing 34, a shell 35 may be provided outside the ball bearing 34. Figure 7 As shown. It is understandable that the housing 35 is provided with a through hole for the dredging member 33 to pass through, and a sealing ring is provided between the through hole and the dredging member 33. Note: The configuration of the sealing ring satisfies: while performing sealing, it will not affect the rotation of the dredging member 33.

[0058] Note: In addition to the above differences, the valve assembly structure and installation method, the structure of the dredging member 33, etc. used in this embodiment 2 are the same as those in embodiment 1, so they are not described here in detail.

[0059] Embodiment 3:

[0060] The third embodiment also provides a rice mill feed blocking prevention structure. Compared with the first embodiment, the third embodiment is different from the first embodiment in that the specific structure of the dredging member 33 is different from that of the first embodiment.

[0061] Specifically, in this embodiment 3, the structure of the dredging member 33 is as follows: Figure 8 As shown, the dredging member 33 includes a rod-shaped main body 330 and a plurality of comb teeth 331 disposed in a radial shape on the main body 330, and the main body 330 is vertically or obliquely disposed on the valve plate 30. It can be understood that by means of the plurality of comb teeth 331, the dredging member 33 can provide a better dredging effect on the material.

[0062] Furthermore, in this embodiment 3, the main body 330 is preferably in the shape of a round rod, the comb teeth 331 are preferably in the shape of a long strip, and the lengths of several comb teeth 331 may be equal or unequal, and several comb teeth 331 may be symmetrically distributed around the vertical center line of the main body 330, or several comb teeth 331 may be arranged irregularly, depending on production requirements.

[0063] Note: In addition to the above-mentioned differences, the valve assembly structure and installation method used in this embodiment 3, the installation method between the dredging member 33 and the valve assembly, etc. are the same as those in embodiment 1, so they are not repeated here.

[0064] Embodiment 4:

[0065] The fourth embodiment also provides a rice milling machine feed blocking prevention structure, and compared with the first embodiment, the fourth embodiment is different in that: ① the number of the valve plate 30 and the driving member 31 is different from that of the first embodiment; ② the shape of the through hole 320 is different from that of the first embodiment.

[0066] Specifically, regarding the above-mentioned difference ①, in the present embodiment 4, the valve plate 30 and the driving member 31 are both configured as two; the two valve plates 30 are arranged side by side on the valve seat 32, and the two driving members 31 can drive the two valve plates 30 to move closer or farther. It can be understood that when the two valve plates 30 are close to each other, the two opposite sides of the two valve plates 30 can fit together to ensure that the feed funnel 2 is completely isolated from the rice milling bin 1.

[0067] Regarding the above-mentioned difference ②, since the valve plates 30 are configured as two, correspondingly, the opposite sides of the through hole 320 are designed to be open, so that the two valve plates 30 can be slidably inserted into the through hole 320 through the above-mentioned two openings and the slide groove combination.

[0068] In addition, the two valve plates 30 are both provided with the dredging member 33. The number of the dredging members 33 is not limited in this embodiment 4 and can be configured according to production requirements.

[0069] Note: In addition to the above two differences, the structure of the dredging member 33 used in this embodiment 4 and the installation method between it and the valve assembly are the same as those in embodiment 1, so they are not described here.

[0070] Embodiment 5:

[0071] This embodiment 5 provides an intelligent rice vending machine, which includes a rice milling machine. A rice milling machine feed anti-blocking structure 3 as provided in any one of the above embodiments 1 to 4 is arranged between the outlet of the feed funnel 2 of the rice milling machine and the inlet of the rice milling bin 1 to dredge the material (such as rice) in the feed funnel 2, thereby facilitating the material to flow smoothly into the rice milling bin 1.

[0072] To sum up, the rice mill feed anti-blocking structure described in the utility model is novel, simple and reasonable, which can not only effectively clear the materials and improve the processing efficiency, but also facilitate the structural installation and electrical control operation, and reduce the production cost; thus, it can be well applied to intelligent rice vending machines.

[0073] In the above description, many specific details are described to facilitate a full understanding of the present invention. However, the above description is only a preferred embodiment of the present invention. The present invention can be implemented in many other ways different from those described herein, so the present invention is not limited by the specific implementation disclosed above. At the same time, any person familiar with the technical field can make many possible changes and modifications to the technical solution of the present invention by using the methods and technical contents disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of protection of the technical solution of the present invention.
