Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a feeding device for a rice milling machine. Background Technology

[0002] Rice enzymatic protein powder is a powdered substance formed from protein extracted from rice through processes such as crushing, purification, and drying. In the production process of rice enzymatic protein powder, rice needs to be ground into powder first.

[0003] Chinese utility model patent CN223010734U discloses a rice milling machine, including a grinding box for grinding rice. A feed hopper is fixedly connected to the top of the grinding box, and a feed pipe for feeding rice is fixedly connected to the bottom of the feed hopper. A pre-grinding mechanism is installed on the feed pipe. A lower grinding disc is fixedly connected inside the grinding box, and a grinding mechanism is installed between the lower grinding disc and the feed pipe. A cleaning and scraping mechanism is installed at the bottom of the lower grinding disc, and a sieving mechanism is installed inside the grinding box. This milling machine can pre-grind the rice, resulting in smaller rice particles, greatly improving the effect and efficiency of subsequent grinding.

[0004] In the above-mentioned utility model patent, when the rice is used, it is poured from the feed hopper into the feed pipe and pre-crushed by the crushing blades in the feed pipe. However, pouring a large amount of rice directly into the feed pipe can easily cause blockage of the feed pipe and cause a sudden increase in the load on the crushing blades, affecting the normal operation of the rice mill. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding device for a rice mill, which solves the problem that the direct feeding of large amounts of rice affects the normal operation of the mill.

[0006] According to an embodiment of this utility model, a rice milling machine feeding device includes a base plate and a feeding pipe vertically arranged on the base plate. A guide pipe is provided on the feeding pipe, the axial direction of which is perpendicular to the axial direction of the feeding pipe and communicates with it. A rotatable main shaft is provided inside the guide pipe. A diverting roller is fixedly connected to the main shaft, and the diverting roller separates the two ends of the feeding pipe. The diverting roller has a groove communicating with the feeding pipe. The main shaft has a central hole, and a protruding protrusion is provided on the inner peripheral wall of the central hole. The base plate also provides a movable drive rod and a drive assembly that is pulverized by the drive rod. The drive rod extends into the central hole, and a spiral groove that mates with the protrusion is provided on the outer peripheral wall of the drive rod. The drive assembly drives the drive rod to reciprocate along the axial direction of the central hole.

[0007] Furthermore, a flow divider is provided at one end of the feed pipe. The flow divider is located below the feed guide pipe. The flow divider and the feed pipe form two feed channels, and the two feed channels are located on opposite sides of the flow divider roller.

[0008] Furthermore, the feed pipe is provided with a feed hopper, which is located above the feed guide pipe.

[0009] Furthermore, the feed tube is provided with a mounting hole, which is coaxially arranged with the feed tube and the main shaft is engaged with the mounting hole.

[0010] Furthermore, the diverting roller is provided with at least two grooves, which are equally spaced along the circumference of the diverting roller.

[0011] Furthermore, the drive assembly includes a drive motor and a transmission rod disposed at the output end of the drive motor. One end of the drive rod is fixedly connected to an adapter block, and the adapter block has a sliding groove. The transmission rod is provided with a connecting pin, and the connecting pin extends into the sliding groove and abuts against the sliding groove.

[0012] Furthermore, one end of the drive rod is provided with a connector and the connector is provided with a connecting rod, and the adapter block is provided with a connecting hole that mates with the connecting rod.

[0013] Furthermore, the base plate is provided with a guide rail, the length direction of which is consistent with the axial direction of the drive rod, and the adapter block is provided with a slider that cooperates with the guide rail.

[0014] Compared to existing technologies, this invention has the following advantages: By employing a main shaft rotatably mounted inside the feed pipe to drive the diverting roller, rice entering the feed pipe first enters the groove on the diverting roller during its rotation. Then, as the diverting roller rotates, it passes through the feed pipe and continues to fall within the feed pipe until it enters the mill. Rice that does not enter the groove is blocked by the diverting roller and remains in the feed pipe, thus achieving intermittent feeding into the mill and preventing blockage at the feed end. Furthermore, the drive rod reciprocates under the drive assembly. During the process, the spiral groove on the drive rod and the protrusion on the main shaft work together to drive the main shaft to rotate back and forth, thereby driving the diverting roller to rotate back and forth. This allows the rice entering the groove to fall into the mill from different positions in the feed pipe, preventing the rice from falling into one place and causing excessive load on the mill. This solves the technical problem of large amounts of rice being poured in directly, which affects the normal operation of the mill. It produces the technical effect of intermittently feeding the mill, avoiding rice from clogging the mill or causing a sudden increase in the mill's load, and improving the stability of the mill during operation.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a rice mill feeding device, which is installed at the feeding end of the mill and is used to feed rice to be processed into the mill.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3The rice mill feeding device includes a base plate 1 and a feed pipe 2 vertically mounted on the base plate 1. A guide pipe 3 is provided on the feed pipe 2, with its axial direction perpendicular to the axial direction of the feed pipe 2 and communicating with the feed pipe 2. A rotatable main shaft 4 is provided inside the guide pipe 3. A diverting roller 5 is fixedly connected to the main shaft 4, separating the two ends of the feed pipe 2. The diverting roller 5 has a groove 51 communicating with the feed pipe 2. After rice is poured into the feed pipe 2, it first falls into the groove 51. As the diverting roller 5 rotates, the rice in the groove 51 passes through the guide pipe 3 and falls from the bottom of the feed pipe 2 into the feed end of the lower mill, thus intermittently feeding rice to be processed into the mill. The main shaft 4 has a central hole, and the central hole... The inner peripheral wall of the central hole is provided with a protruding protrusion 41. The base plate 1 is also provided with a movable drive rod 6 and a drive assembly 7 that is connected to the drive rod 6 in a transmission manner. The drive rod 6 extends into the central hole and the outer peripheral wall of the drive rod 6 is provided with a spiral groove 61 that cooperates with the protrusion 41. The drive assembly 7 drives the drive rod 6 to move back and forth along the axial direction of the central hole. During the reciprocating movement of the drive rod 6 under the drive assembly 7, the cooperation between the spiral groove 61 and the protrusion 41 drives the main shaft 4 to rotate back and forth, so that the diverting roller 5 rotates back and forth under the drive of the main shaft 4 and causes the rice in the groove 51 to fall from different positions of the guide pipe 3 into the feed end of the mill, avoiding the rice from falling into the same position of the mill and causing a sudden increase in the load of the mill.

[0020] Specifically, the working process of the rice mill feeding device provided in this embodiment is as follows: the drive assembly 7 is started and the rice to be processed is poured into the feed pipe 2. During the reciprocating movement of the drive rod 6 driven by the drive assembly 7, the main shaft 4 is driven to rotate reciprocally through the cooperation of the spiral groove 61 and the protrusion 41, which in turn drives the diverting roller 5 to rotate reciprocally. During the rotation of the diverting roller 5, the rice entering the feed pipe 2 first falls into the groove 51, and then, with the rotation of the diverting roller 5, it passes through the guide pipe 3 and continues to fall in the feed pipe 2 until it enters the mill. The rice that does not enter the groove 51 is blocked by the diverting roller 5 and remains in the feed pipe 2, thereby realizing intermittent feeding into the mill. During the reciprocating rotation of the diverting roller 5, the rice can fall into the mill from different positions in the guide pipe 3, avoiding blockage at the feed end of the mill and preventing the rice from falling into one place in the mill, which would cause the mill to be overloaded. The rice mill feeding device provided in this embodiment can intermittently feed rice into the mill, preventing the rice from clogging the mill or causing a sudden increase in the load on the mill, which helps to improve the stability of the mill during operation.

[0021] like Figure 4As shown, a diverter plate 21 is provided at one end of the feed pipe 2. The diverter plate 21 is located below the guide pipe 3. The diverter plate 21 and the feed pipe 2 form two feed channels 22, and the two feed channels 22 are respectively located on opposite sides of the diverter roller 5. The diverter plate 21, which is provided in the feed pipe 2, is used to form the feed channels 22 with the guide pipe 3 to guide the rice falling from the groove 51 into the mill. This ensures that the rice enters the feed end of the mill along different feed channels 22 during the reciprocating rotation of the diverter roller 5, thus ensuring that the rice is dispersed into the mill.

[0022] In this embodiment, the feed pipe 2 is provided with a feed hopper 23, which is located above the guide pipe 3. The feed hopper 23 is used to guide rice into the feed pipe 2. Pouring the rice to be processed into the feed hopper 23 allows the rice to slowly fall into the feed pipe 2, preventing rice from falling outside the feed pipe 2 and causing loss.

[0023] like Figure 2 As shown, the feed tube 3 is provided with a mounting hole, which is coaxially arranged with the feed tube 3, and the main shaft 4 cooperates with the mounting hole. The main shaft 4 is installed into the feed tube 3 through the cooperation with the mounting hole, ensuring a stable cooperation between the main shaft 4 and the feed tube 3, and allowing the main shaft 4 to rotate smoothly within the feed tube 3, which helps to improve the structural stability of the rice mill feeding device.

[0024] Please refer to Figure 2 and Figure 4 The diverting roller 5 is provided with at least two grooves 51, which are evenly spaced along the circumference of the diverting roller 5. By providing multiple grooves 51 on the diverting roller 5, rice sequentially enters each groove 51 during the rotation of the diverting roller 5 and passes through the guide tube under the drive of the diverting roller 5. This increases the frequency of adding rice into the mill, thereby improving processing efficiency while ensuring stable operation of the mill.

[0025] Please combine Figure 1 and Figure 2The drive assembly 7 includes a drive motor 71 and a transmission rod 72 disposed at the output end of the drive motor 71. One end of the drive rod 72 is fixedly connected to an adapter block 62, and the adapter block 62 has a sliding groove 63. The transmission rod 72 is provided with a connecting pin, which extends into the sliding groove 63 and abuts against the sliding groove 63. When the transmission rod 72 rotates under the drive of the drive motor 71, the connecting pin slides in the sliding groove 63 and pushes or pulls the adapter block 62 to reciprocate, causing the transmission rod 72 to reciprocate under the drive of the adapter block 62, thereby driving the main shaft 4 to reciprocate and rotate, so that the rice mill feeding device operates smoothly.

[0026] In detail, one end of the drive rod 6 is provided with a connector 64, and the connector 64 is provided with a connecting rod 65. The adapter block 62 is provided with a connecting hole that mates with the connecting rod 65. The adapter block 62 is fixedly connected to the connector 64 through the connection hole and the connection rod 65, so that the adapter block 62 and the drive rod 6 are securely connected, preventing the adapter block 62 from accidentally disengaging from the drive rod 6.

[0027] As shown in the figure, a guide rail 11 is provided on the base plate 1. The length direction of the guide rail 11 is consistent with the axial direction of the drive rod 6, and a slider 66 that cooperates with the guide rail 11 is provided on the adapter block 62. The guide rail 11 on the base plate 1 is used to cooperate with the slider 66 to limit the movement direction of the adapter block 62, prevent the adapter block 62 from deviating from the preset direction or undergoing unexpected deflection when moving, and ensure that the adapter block 62 remains stable when moving on the base plate 1, which helps to improve the reliability of the rice mill feeding device.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
