Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0048] The following is combined with Figures 1 to 10 This application describes the rock grinding machine, control method, and storage medium.

[0049] According to the embodiments of the first aspect of this application, such as Figure 1 As shown, the control method for the rock grinding machine includes:

[0050] The rock grinding machine includes a motor 2 and a drum 1, wherein the motor 2 drives the drum 1 to rotate, and the control method includes:

[0051] Step 101: Determine that the actual rotational speed of the roller 1 is different from the standard rotational speed;

[0052] Step 102: Based on the actual speed and the standard speed, determine the adjustment voltage of the motor 2;

[0053] Step 103: Control the operation of the motor 2 based on the adjusted voltage.

[0054] According to the rock grinding machine control method of this application embodiment, the actual rotation speed of the drum 1 is first obtained, and the actual rotation speed of the drum 1 is compared with the standard rotation speed. When the difference between the actual rotation speed and the standard rotation speed is less than a threshold, the motor 2 is controlled to maintain the current voltage, that is, the adjustment voltage value of the motor 2 is 0. When the difference between the actual rotation speed and the standard rotation speed is greater than the threshold, the adjustment voltage of the motor 2 is determined according to the actual rotation speed and the standard rotation speed. Then, the operation of the motor 2 is controlled based on the adjustment voltage, so that the motor 2 can adjust the rotation speed of the drum 1 to the standard rotation speed, thereby ensuring the stability of the rotation speed of the drum 1 and avoiding the impact of inconsistent speed on the grinding effect and grinding time.

[0055] It should be noted that adjusting the voltage refers to the voltage value that the operating voltage of motor 2 needs to be changed.

[0056] In some embodiments, the standard rotational speed can be set by the user.

[0057] In some embodiments, the step of determining that the actual rotational speed of the roller 1 differs from the standard rotational speed includes:

[0058] Based on the working gear of the rock grinder, the standard rotation speed of the roller 1 is determined;

[0059] Based on the detection data from the photoelectric sensor, the real-time rotational speed of the roller 1 is determined. The photoelectric sensor is used to detect the rotational speed of the roller 1.

[0060] When the difference between the standard rotational speed and the real-time rotational speed is greater than a threshold, it is determined that the actual rotational speed of the roller 1 is different from the standard rotational speed.

[0061] Understandably, when it is determined that the actual speed of the roller 1 is different from the standard speed, the standard speed of the roller 1 is first determined according to the working gear of the rock grinder, and then the real-time speed of the roller 1 is determined according to the detection data of the photoelectric sensor. If the difference between the standard speed and the real-time speed is greater than the threshold, it means that the actual speed of the roller 1 is different from the standard speed. Subsequently, the working voltage of the motor 2 is adjusted to adjust the speed of the roller 1 to the standard speed.

[0062] In some embodiments, after determining that the actual rotational speed of the roller 1 is different from the standard rotational speed, the method further includes:

[0063] The target voltage of the motor 2 is determined based on the actual load-bearing weight and standard rotation speed of the roller 1.

[0064] The operation of the motor 2 is controlled based on the target voltage.

[0065] It is understandable that the actual load-bearing weight of roller 1 will affect its actual rotation speed. Therefore, after determining that the actual rotation speed of roller 1 is different from the standard rotation speed, the target voltage of motor 2 can be determined based on the actual load-bearing weight of roller 1 and the standard rotation speed. That is, it can be determined at what working voltage of motor 2 can drive roller 1 to rotate at the standard rotation speed. Then, the operation of motor 2 is controlled according to the target voltage.

[0066] It is understandable that the smaller the actual load-bearing weight, the smaller the target voltage of motor 2.

[0067] In some embodiments, such as Figure 9 As shown, the roller 1 includes an inner roller 13 and an outer roller 14. The inner roller 13 is disposed inside the outer roller 14 and is connected to the outer roller 14. An outer grinding cavity 15 is formed between the inner roller 13 and the outer roller 14. An inner grinding cavity 16 is formed in the inner roller 13. An opening is formed at the end of the roller 1. Both the outer grinding cavity 15 and the inner grinding cavity 16 are connected to the opening.

[0068] Understandably, the rock grinder includes a cover plate that can be placed over the opening of the roller 1. When the cover plate is opened, the outer grinding chamber 15 and the inner grinding chamber 16 can be connected to the outside.

[0069] The inner grinding chamber 16 and the outer grinding chamber 15 are independent of each other, so rocks can be placed in the inner grinding chamber 16 and the outer grinding chamber 15 respectively, that is, different grinding tasks can be performed by the inner grinding chamber 16 and the outer grinding chamber 15 respectively.

[0070] According to an embodiment of the second aspect of this application, the rock grinding machine control method includes:

[0071] The operation of the rock grinding machine is controlled based on the set parameters;

[0072] Understandably, users preset grinding parameters and store them in the control unit. These preset parameters may include the total grinding time and the rotational speed of roller 1 of the rock grinder. After the rock grinder starts working, the remaining grinding time is updated in real time, and the real-time rotational speed of roller 1 is stored.

[0073] When the rock grinder malfunctions, the operating data of the rock grinder is stored.

[0074] Understandably, when the rock grinder experiences abnormalities such as power failure, malfunction shutdown, or overcurrent protection shutdown, the rock grinder will pause grinding and store the rock grinder's working data, such as the accumulated grinding time and current speed.

[0075] After the abnormality of the rock grinder is eliminated, the rock grinder is controlled to continue working based on the set parameters and the working data.

[0076] Understandably, once the malfunction of the rock grinder is resolved, it means that the rock grinder can continue to work. At this point, based on the set parameters and working data, the remaining grinding time of the grinder can be determined, as well as the rotational speed of roller 1 when the malfunction occurred. Therefore, based on the set parameters and working data, the rock grinder can be controlled to continue working, ensuring a continuous and uninterrupted rock grinding process. Users do not need to reset parameters, thus guaranteeing the effectiveness of rock grinding.

[0077] According to the rock grinding machine control method of this application embodiment, the operation of the rock grinding machine is first controlled according to the set parameters. If the rock grinding machine encounters an abnormality before completing grinding, the working data of the rock grinding machine is stored when the abnormality occurs. After the abnormality of the rock grinding machine is eliminated, that is, when the rock grinding machine can continue grinding, the rock grinding machine is controlled to continue working according to the set parameters and the working data when the abnormality occurred. This allows the rock grinding machine to continue the grinding operation before the abnormality occurred without the user having to reset the grinding parameters. The operation is simple and convenient, which helps to ensure the grinding effect.

[0078] In some examples, the setting parameters include a standard sanding time, which represents the total time required to complete the sanding process.

[0079] In some examples, the working data includes the working setting and actual grinding time when the rock grinder malfunctions. After the malfunction is resolved, the remaining grinding time can be determined based on the actual grinding time when the malfunction occurred and the set standard grinding time. Then, the rock grinder is controlled to work according to the remaining grinding time and the working setting when the malfunction occurred, ensuring the continuity of rock grinding, simplifying the operation, and guaranteeing the effect of rock grinding.

[0080] In some embodiments, the step of storing the operating data of the rock grinder when the rock grinder malfunctions includes:

[0081] When the rock grinder malfunctions, the working data of the rock grinder is stored.

[0082] It is understandable that when a rock grinder malfunctions, it indicates that the rock grinder is malfunctioning and will stop grinding. Therefore, the working data of the rock grinder is stored at this time so that when the fault is resolved, the rock grinder can be controlled to continue working based on the stored working data.

[0083] In some embodiments, the step of storing the operating data of the rock grinder when the rock grinder malfunctions includes:

[0084] When the rock grinder experiences an abnormal power outage, the operating data of the rock grinder is stored.

[0085] It is understandable that when the rock grinder experiences an abnormal power outage, it indicates that the rock grinder is malfunctioning and will stop grinding. Therefore, the working data of the rock grinder is stored at this time so that when the rock grinder is powered back on, the stored working data can be used to control the rock grinder to continue working.

[0086] In some embodiments, the step of storing the operating data of the rock grinder when the rock grinder malfunctions includes:

[0087] When the current of the rock grinder is greater than a preset current value, the working data of the rock grinder is stored.

[0088] It is understandable that when the current of the rock grinder exceeds the preset current value, it indicates that the rock grinder is malfunctioning and will stop grinding. Therefore, the working data of the rock grinder is stored at this time so that the rock grinder can be controlled to continue working later based on the stored working data.

[0089] In some embodiments, the step of controlling the operation of the rock grinder based on set parameters includes:

[0090] The operation of the rock grinder is controlled based on the set total duration and standard rotation speed.

[0091] Understandably, the settings include setting the total duration and standard speed. Based on the set total duration and standard speed, the speed of the roller 1 of the rock grinder is controlled to remain at the standard speed. At the same time, timing is started after the rock grinder starts working, so that the rock grinder grinds according to the set total duration.

[0092] In some embodiments, after the step of controlling the operation of the rock grinder, the following is included:

[0093] It was determined that the actual rotational speed of the rock grinder differed from the standard rotational speed.

[0094] Based on the actual rotational speed, adjust the set total duration of the rock grinder.

[0095] Understandably, the rotation speed of the rock grinder, specifically the rotation speed of the roller 1, affects the grinding process. The faster the roller 1 rotates, the faster the grinding speed, and the faster the rock can be ground.

[0096] During the operation of the rock grinder, the rotation speed of the roller 1 of the rock grinder is detected in real time using photoelectric sensors and other detection elements. When it is determined that the actual rotation speed of the roller 1 of the rock grinder is different from the standard rotation speed, the total set time of the rock grinder is adjusted in real time according to the actual rotation speed to ensure that the grinding effect of the rock meets the expectations after the grinding is completed.

[0097] It is understandable that when the power grid supply voltage is insufficient, the actual speed of the rock grinder will be lower than the standard speed, and because the power supply voltage is insufficient, it is difficult to adjust the speed by adjusting the voltage.

[0098] In some examples, if the actual rotational speed is greater than the standard rotational speed, the total set time is shortened; if the actual rotational speed is less than the standard rotational speed, the total set time is increased.

[0099] In some cases, there is a linear relationship between rotational speed and total duration.

[0100] Specifically, the step of controlling the rock grinder to continue working based on the set parameters and the working data includes:

[0101] The operation of the rock grinder is controlled based on the difference between the total working time of the rock grinder before the abnormality occurred and the set total working time of the rock grinder after adjustment.

[0102] Understandably, after adjusting the total set time of the rock grinder according to the actual rotation speed, if the rock grinder malfunctions, the operation of the rock grinder will be controlled based on the difference between the total working time of the rock grinder before the malfunction and the adjusted total set time after the malfunction is eliminated. This ensures that the working time of the rock grinder matches the adjusted total set time, thus guaranteeing the rock grinding effect.

[0103] According to an embodiment of the third aspect of this application, the rock grinder includes a control component for performing the rock grinder control method described above.

[0104] In some embodiments, such as Figure 3 , Figure 4 and Figure 5As shown, the rock grinding machine includes an MCU, a parameter storage chip, a photoelectric detection circuit, a photoelectric sensor, a motor 2 control circuit, and a motor 2. The parameter storage chip is connected to the MCU and is used to store the real-time operating parameters of the rock grinding machine. The photoelectric sensor, the photoelectric detection circuit, and the MCU are connected in sequence. The photoelectric detection circuit is used to drive the photoelectric sensor, which is used to detect the rotational speed of the roller 1 of the rock grinding machine. The motor 2, the motor 2 control circuit, and the MCU are connected in sequence. The motor 2 control circuit is used to drive the motor 2, which is used to drive the roller 1 to rotate.

[0105] In some embodiments, such as Figure 6 As shown, the roller 1 includes a first grinding part 11 and a second grinding part 12 connected in sequence. The first grinding part 11 forms a first grinding cavity 111, and the second grinding part 12 forms a second grinding cavity 121. The grinding precision of the first grinding part 11 is less than that of the second grinding part 12.

[0106] The rock grinder also includes a pushing component 3, which is used to push the rock in the first grinding chamber 111 to the second grinding chamber 121.

[0107] Understandably, the rock to be polished is first placed in the first polishing chamber 111, and the roller 1 is rotated by the motor 2 to polish the rock using the first polishing chamber 111, thus achieving preliminary polishing of the rock. Then, the rock is pushed into the second polishing chamber 121 by the pushing component 3, and the rock is polished a second time using the second polishing chamber 121, which helps to improve the precision of rock polishing.

[0108] Specifically, such as Figure 6 As shown, the pushing assembly 3 includes a pushing drive 31 and a push plate 32. The push plate 32 is disposed in the first grinding cavity 111 and is slidably connected to the cavity wall of the first grinding cavity 111. The pushing drive 31 is connected to the push plate 32 and is used to drive the push plate 32 to move so that the push plate 32 can push the rock in the first grinding cavity 111 to the second grinding cavity 121.

[0109] It is understandable that the push plate 32 is slidably connected to the cavity wall of the first grinding cavity 111, which ensures that the push plate 32 can move relative to the first grinding cavity 111, thereby pushing the rock in the first grinding cavity 111 to the second grinding cavity 121. At the same time, it ensures that the push plate 32 abuts against the cavity wall of the first grinding cavity 111, thereby ensuring that the push plate 32 can push all the rock in the first grinding cavity 111 to the second grinding cavity 121.

[0110] In some examples, the driving component 31 is, for example, a cylinder. The cylinder is located outside the roller 1 and is connected to a push rod. The roller 1 has a connecting hole, and the push rod passes through the connecting hole and connects to the push plate 32, thereby enabling the cylinder to drive the push plate 32 to move.

[0111] In some embodiments, such as Figure 6 As shown, the rock grinding machine also includes a separator 4, which is inserted into the roller 1. The separator 4 is movable relative to the roller 1 so that it can switch between a first position and a second position. In the first position, the separator 4 separates the first grinding chamber 111 and the second grinding chamber 121. In the second position, the first grinding chamber 111 and the second grinding chamber 121 are in communication.

[0112] It is understandable that placing the separator 4 in the first position can separate the first grinding chamber 111 and the second grinding chamber 121, thus preventing the rocks in the first grinding chamber 111 and the second grinding chamber 121 from mixing.

[0113] When it is necessary to push the rock in the first grinding chamber 111 into the second grinding chamber 121, the separator 4 is in the second position. At this time, the separator 4 no longer separates the first grinding chamber 111 and the second grinding chamber 121. The first grinding chamber 111 and the second grinding chamber 121 are connected. The push plate 32 can move from the first grinding chamber 111 to the second grinding chamber 121, thereby pushing the rock in the first grinding chamber 111 into the second grinding chamber 121.

[0114] In some examples, the roller 1 is formed with a insertion hole into which the separator 4 can be inserted. When the separator 4 is inserted into the insertion hole, the separator 4 is in a first position, and when the separator 4 is withdrawn from the insertion hole, the separator 4 is in a second position.

[0115] In some embodiments, the cavity wall of the second grinding cavity 121 is inclined, and along the direction from the first grinding cavity 111 to the second grinding cavity 121, the cavity wall of the second grinding cavity 121 gradually inclines away from the center of the roller 1.

[0116] Understandably, by setting the cavity wall of the second grinding chamber 121 to an inclined position, when the pushing component 3 pushes the rock from the first grinding chamber 111 into the second grinding chamber 121, the rock will slide down the cavity wall of the second grinding chamber 121 and gradually move away from the second grinding chamber 121. This effectively prevents the rock pushed into the second grinding chamber 121 from rolling back into the first grinding chamber 111. At the same time, it can prevent rocks from accumulating at the junction of the first grinding chamber 111 and the second grinding chamber 121, preventing the separator 4 from being unable to switch from the second position to the first position due to rock obstruction.

[0117] Specifically, such as Figure 6 As shown, the first polishing part 11 includes a body part 112 and a connecting part 113 connected in sequence. The body part 112 forms the first polishing cavity 111, and the connecting part 113 forms a transition cavity 1131. The first polishing cavity 111 communicates with the transition cavity 1131. The transition cavity 1131 is located between the first polishing cavity 111 and the second polishing cavity 121. Along the direction from the first polishing cavity 111 to the second polishing cavity 121, the cavity wall of the transition cavity 1131 gradually slopes away from the center of the first polishing cavity 111.

[0118] It is understandable that when the rock moves from the first grinding chamber 111 to the transition chamber 1131, the rock will roll towards the second grinding chamber 121 under the action of the inclined cavity wall of the transition chamber 1131, which will facilitate the movement of the rock in the first grinding chamber 111 into the second grinding chamber 121.

[0119] Meanwhile, since the wall of the transition cavity 1131 is gradually inclined toward the second grinding cavity 121, it can effectively prevent the rock in the second grinding cavity 121 from rolling back into the first grinding cavity 111.

[0120] In some embodiments, such as Figure 6 As shown, the rock grinding machine also includes a motor 2, a primary disk 5, and a secondary disk 6. The secondary disk 6 is fixedly connected to the inner wall of the roller 1. The primary disk 5 and the secondary disk 6 are magnetically attracted to each other. The motor 2 is connected to the primary disk 5 and is used to drive the primary disk 5 to rotate.

[0121] It is understandable that, since the primary disk 5 and the secondary disk 6 are magnetically attracted, when the motor 2 drives the primary disk 5 to rotate, the secondary disk 6 will rotate as well, thereby causing the roller 1 to rotate as well, thus achieving rotation control of the roller 1.

[0122] Compared to the related technologies that use belts to drive the roller 1 to rotate, this application uses magnetic force to drive the roller 1 to rotate, which is beneficial to the simplification of the rock grinding machine structure and makes the structure more stable.

[0123] Specifically, such as Figure 7 and Figure 8 As shown, the primary disk 5 has its N and S poles arranged alternately in a ring, and the secondary disk 6 has its S and N poles arranged alternately in a ring. The N pole of the primary disk 5 is positioned opposite to the S pole of the secondary disk 6, and the S pole of the primary disk 5 is positioned opposite to the N pole of the secondary disk 6.

[0124] Understandably, the S pole of the secondary disk 6 corresponds to the N pole of the primary disk 5, and the N pole of the secondary disk 6 corresponds to the S pole of the primary disk 5. This causes the primary disk 5 and the secondary disk 6 to be magnetically attracted to each other. When the primary disk 5 rotates, it can drive the secondary disk 6 to rotate because of the magnetic attraction between the primary disk 5 and the secondary disk 6. Furthermore, since the S pole of the secondary disk 6 is magnetically attracted to the N pole of the primary disk 5, and both sides of the N pole of the primary disk 5 are S poles, the S pole of the secondary disk 6 will magnetically repel the S poles on both sides of the N pole of the primary disk 5. This ensures that the primary disk 5 will not slip when driving the secondary disk 6 to rotate, allowing the primary disk 5 to drive the secondary disk 6 to rotate more stably.
