Description

Technical Field

[0001] The utility model relates to the technical field of rice milling machines, in particular to a rice discharging mechanism of a rice milling machine and an intelligent rice vending machine. Background Art

[0002] The rice milling machine is a common equipment in rice production and processing, which usually includes a rice milling bin and an auger, wherein the rice milling bin is provided with an outer shell, an inner bin built in the outer shell, a feed port connecting the outer shell and the inner bin, a rice outlet connecting the outer shell and the inner bin, and a bran outlet provided in the outer shell, and the inner bin is provided with a sieve hole that leaks bran but not rice; the auger (with a spiral rice milling blade) is rotated and built in the inner bin. When the rice enters the inner bin from the feed port, the auger can transport, grind, shell and remove the rice to obtain rice, and then flow out from the rice outlet. The bran produced during the rice milling process falls into the outer shell from the sieve hole and is then discharged from the bran outlet.

[0003] In order to improve the whiteness of rice processed by a rice mill, or to enable the rice mill to process rice of various whiteness levels to meet the needs of different consumer groups, a baffle is currently set at the rice outlet of the rice mill to control the speed at which rice is pushed out of the rice outlet (or called the rice outlet speed). The slower the rice outlet speed, the longer the rice stays in the inner bin, so that it is more fully ground and the obtained rice has a higher whiteness level.

[0004] However, the current method for adjusting the whiteness of rice has the following shortcomings: ① The shape of the baffle currently used is generally the same as the shape of the rice outlet of the rice mill. In order to obtain rice with high whiteness, the gap between the baffle and the rice outlet is adjusted to a very small size. The rice flowing out of the rice outlet of the rice mill is in a high-temperature and high-speed state. Therefore, the rice flowing out of the rice outlet will hit the baffle and break, which seriously affects the quality of the rice. ② At present, the gap between the baffle and the rice outlet is mainly adjusted manually. The manual adjustment method is not only inconvenient to operate, but also has poor accuracy and consistency during operation, and poor adaptability to different specifications of rice, so that the resulting rice often fails to meet the ideal whiteness requirements.

[0005] In view of this, the present utility model is proposed. Summary of the invention

[0006] In order to overcome the above-mentioned defects, the utility model provides a rice milling machine rice discharging mechanism and an intelligent rice vending machine, which have a simple and reasonable structure, can automatically and highly accurately adjust the rice whiteness and grade, and can effectively improve the integrity of rice grains and other qualities, thus meeting production needs well.

[0013] As a further improvement of the present invention, the mounting portion and the baffle member are both vertically arranged and have a U-shaped trough structure in transverse cross section, the U-shaped notches of the mounting portion and the baffle member are also arranged opposite to each other, and the baffle member is also rotatably connected to the mounting portion via a rotating shaft;

[0014] The flow channel portion is connected to the mounting portion in a downwardly inclined manner; accordingly, an inclined end surface that can be fitted and matched with the bottom plate of the flow channel portion is formed on the lower side of the baffle member.

[0015] As a further improvement of the present invention, the adjusting mechanism includes a motor fixedly arranged on the mounting portion and a push rod connected to the baffle member and connected to the output shaft of the motor through a transmission assembly.

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Embodiment 1:

[0030] This embodiment 1 provides a rice milling machine rice outlet mechanism, which is arranged at the rice outlet of the rice milling bin 2 (same as the background technology, the rice milling bin 2 is also provided with an outer shell, an inner bin, a feed port, a rice outlet, a bran outlet, etc.), and can automatically and accurately adjust the rice whiteness and grade, and can effectively improve the integrity of rice grains and other qualities, thus meeting the production needs well.

[0031] Please refer to the attached Figure 1 To Attachment Figure 4 As shown, the rice milling machine rice discharging mechanism 1 described in this embodiment 1 includes a rice discharging component 1A and an adjusting mechanism 1B, wherein the rice discharging component 1A is provided with a rice discharging channel 10 and a baffle member 11 that can partially enclose the rice discharging channel 10 to form a receiving chamber 12, and the receiving chamber 12 is provided to cover and communicate with the rice discharging port of the rice milling bin 2, so as to perform transition receiving, temperature reduction, pressure relief and speed reduction on the rice flowing out of the rice discharging port; it can be understood that, by virtue of the configuration of the receiving chamber 12, when the rice enters the receiving chamber 12, it will be cooled, pressure relieved and speed reduced, thereby effectively reducing the breakage rate of the rice hitting the baffle member 11, and further effectively improving the integrity of the rice grains; the adjusting mechanism 1B is provided at the rice discharging channel 10, and electrically drives the baffle member 11 to rotate, so as to automatically adjust the discharging speed of the rice flowing out of the receiving chamber 12, thereby realizing automatic and high-precision adjustment of the rice whiteness and its grade.

[0032] The specific structure of the rice discharging mechanism of the rice milling machine described in this embodiment 1 is described in detail below.

[0033] First, regarding the rice discharging assembly 1A.

[0034] Please continue to refer to the attached Figure 1 To Attachment Figure 4As shown, in the structure of the rice outlet assembly 1A provided in the present embodiment 1, the rice outlet flow channel 10 includes a mounting portion 101 fixedly arranged on the outside of the rice outlet, a rice inlet 102 arranged on the mounting portion 101 and communicating with the rice outlet, and a flow channel portion 103 connected to the lower side of the mounting portion 101; the baffle member 11 is rotatably arranged on the mounting portion 101, and together with the mounting portion 101 and the upper side of the flow channel portion 103, encloses the accommodating cavity 12. It can be understood that the receiving chamber 12 is connected to the rice outlet of the rice milling bin 2 through the rice inlet 102, and the baffle member 11 can be rotated relative to the mounting portion 101, so that the positional relationship between the baffle member 11 and the flow channel portion 103 can be changed, which is specifically manifested in that the gap between the baffle member 11 and the upper side of the flow channel portion 103 can be adjusted, thereby adjusting the outlet speed of rice from the receiving chamber 12 (specifically the above-mentioned gap).

[0035] Further, the preferred implementation structure of the receiving chamber 12 is: Figure 2 To Attachment Figure 4 As shown, the mounting portion 101 and the baffle member 11 are both vertically arranged and have a U-shaped trough structure in transverse cross section. The U-shaped notches of the mounting portion 101 and the baffle member 11 are also arranged relative to each other, and the baffle member 11 is also rotatably connected to the mounting portion 101 through a rotating shaft 13; the flow channel portion 103 is connected to the mounting portion 101 in a downwardly inclined manner, and accordingly, the lower side of the baffle member 11 forms an inclined end surface that can fit with the bottom plate 1030 of the flow channel portion 103. It can be understood that the receiving chamber 12 is mainly formed by two U-shaped troughs (the mounting portion 101 and the baffle member 11) and a bottom plate (bottom plate 1030), the upper side of which is open, the lower side can be opened or closed, and the volume can be freely configured according to needs, so that it can not only effectively achieve the cooling of rice, pressure relief and speed reduction, but also can be conveniently controlled to adjust the rice output speed.

[0036] Supplementary explanation: The volume of the receiving chamber 12 will not be designed to be very large, but it will be larger than the gap between the baffle and the rice outlet in the prior art. Therefore, compared with the prior art, the receiving chamber 12 described in this embodiment 1 can achieve a certain degree of temperature reduction, pressure relief and speed reduction for the rice.

[0037] In addition, regarding the matching arrangement between the mounting portion 101 and the baffle member 11, the present embodiment 1 further makes the following preferred design: the U-shaped notch of the mounting portion 101 is designed to be larger than the U-shaped notch of the baffle member 11, so that during assembly, the baffle member 11 is inserted and rotatably arranged in the mounting portion 101. The reason for adopting the above design is to precisely control the gap between the lower side of the baffle member 11 and the bottom plate 1030.

[0038] In addition, in order to achieve a buffering effect on the rice during the falling process on the flow channel portion 103, the present embodiment 1 further designs the bottom plate 1030 of the flow channel portion 103 to be multiple, and the multiple bottom plates 1030 are arranged in a step-like manner from top to bottom. For details, please refer to the attached Figure 1 To Attachment Figure 4 As shown, it is understandable that the lower side of the baffle member 11 is in abutment with the bottom plate 1030 located at the top.

[0039] Next, let us discuss the adjustment mechanism 1B.

[0040] Based on the specific structure of the above-mentioned rice discharging component 1A, the adjusting mechanism 1B provided in this embodiment 1 is arranged on the mounting portion 101; and when the adjusting mechanism 1B drives the baffle member 11 to rotate, the lower side of the baffle member 11 can be tightly abutted against or separated from the upper side of the flow channel portion 103, that is, the lower side of the receiving cavity 12 is closed or opened; and the separation gap between the lower side of the baffle member 11 and the upper side of the flow channel portion 103 can be adjusted, that is, the rice discharging speed flowing out of the receiving cavity 12 can be adjusted.

[0041] Furthermore, the preferred implementation structure of the adjustment mechanism 1B in this embodiment 1 is: Figure 1 To Attachment Figure 4 As shown, the adjustment mechanism 1B includes a motor 14 fixedly arranged on the mounting portion 101 and a push rod 15 connected to the baffle member 11 and connected to the output shaft of the motor 14 through a transmission assembly. The push rod 15 can perform transverse linear motion under the coordinated drive of the motor 14 and the transmission assembly, thereby driving the baffle member 11 to rotate (a slight rotation).

[0042] Regarding the above-mentioned transmission assembly, the preferred implementation structure of this embodiment 1 is: the transmission assembly includes a transversely arranged transmission shaft 16, two synchronous wheels 17 respectively fixedly mounted on the transmission shaft 16 and the power output shaft of the motor 14, and a synchronous belt 18 mounted on the two synchronous wheels 17, and the transmission shaft 16 and the push rod 15 are coaxially arranged and threadedly connected.

[0043] Furthermore, the threaded connection between the transmission shaft 16 and the push rod 15 is as follows: one end of the transmission shaft 16 extends into the push rod 15 and is threadedly connected to the push rod 15, that is, the push rod 15 adopts a hollow structure or is provided with a hollow section, and an internal thread section is provided in the hollow cavity of the push rod 15; one end of the transmission shaft 16 is provided with an external thread section that is threadedly matched with the above-mentioned internal thread section.

[0044] Regarding the manner in which the push rod 15 is connected to the baffle member 11, the preferred implementation structure of this embodiment 1 is that the push rod 15 is movably passed through the baffle member 11, and limiting columns 19 are provided on the push rod 15 and at positions on opposite sides of the baffle member 11.

[0045] Furthermore, a spring is arranged between the limiting column 19 and the baffle member 11, and the spring is also sleeved outside the push rod 15. Note: According to processing requirements, the spring is arranged between the baffle member 11 and a limiting column 19 on its outer side to elastically constrain the baffle member 11. Of course, this embodiment does not impose any restrictions on the arrangement position of the spring, which is specifically determined according to the structure of the push rod 15 and the connection method with the baffle member 11.

[0046] In addition, in the rice milling machine rice discharging mechanism described in the present embodiment 1, in addition to the rice discharging assembly 1A and the adjusting mechanism 1B, other structures are also configured, such as: an auxiliary hand wheel 110 is also provided, and the auxiliary hand wheel 110 is connected to the other end of the transmission shaft 16 facing away from the push rod 15. The purpose of configuring the auxiliary hand wheel is: when the motor 14 fails, the baffle member 11 can be adjusted to the desired state by manually adjusting the auxiliary hand wheel 110 to meet the emergency standby needs during the processing.

The rice outlet of the rice milling bin 2 of the rice milling machine is provided with a rice milling machine rice outlet mechanism as provided in embodiment 1, and the rice milling machine rice outlet mechanism can optimize and / or automatically adjust the quality of rice particles, rice whiteness and grade.

[0049] To sum up, the rice discharging mechanism of the rice milling machine described in the utility model has a simple and reasonable structure, can automatically and accurately adjust the whiteness and grade of rice, and can effectively improve the integrity of rice grains and other qualities, which meets production needs well and can be well applied to intelligent rice vending machines.
