[0001] The invention relates to the technical field of processing equipment, and in particular to a grinding device for a plow blade. Background Art

[0002] The plow blade is generally made of metal, and its shape is usually triangular with a sharp front end, which needs to be polished so that it can easily cut into the soil. Due to the particularity of the shape of the plow blade, when polishing the edge of the plow blade, the polishing method is adjusted according to the curvature of the plow blade. In the prior art, the plow blade is usually polished manually, which completely relies on the experience and skills of the operator.

The third moving block 215 is fixedly connected to the third slider 212, and the third slider 212 is driven to move synchronously by the third moving block 215. The third slider 212 consists of two pieces, and is symmetrically slidably installed on the third slide rail 211 along the length direction. The first fixing member 216 and the second fixing member 217 are respectively installed on the two third sliders 212.

[0029] Before grinding, first place the plow blade between the first fixing member 216 and the second fixing member 217, and then start the third motor 213 to make the first fixing member 216 and the second fixing member 217 approach each other. During the approaching process, one of the limit rods cooperates with the turntable 2172 to fix the plow blade, so that the edge of one side of the plow blade can be grinded; after grinding is completed, start the sixth motor 2173, the limit rod fixing the plow blade gradually moves away from the turntable 2172, and the other limit rod gradually approaches the turntable 2172 until the plow blade is clamped, so that while driving the plow blade to flip, the limit rod clamping the plow blade is switched to facilitate grinding the other side of the plow blade.

[0030] The cleaning assembly 3 includes: a fan 31, a mounting part 32 installed on the top of the machine, a telescopic tube 34 slidably mounted on the mounting part 32, a cleaning part 33 connected to the extended end of the telescopic tube 34, a wiping part 35 for wiping the plow blade after cleaning, and the wiping part 35 is connected to the cleaning part 33; the telescopic tube 34 is preferably a rectangular telescopic tube 34.

[0031] The cleaning member 33 includes: a shell 331 connected to the air outlet end of the telescopic tube 34, a rotating block 332 coaxially mounted on the bottom of the shell 331, and bristles 333 mounted on the rotating block 332; a plurality of fine holes 334 are provided on the rotating block 332, and the aperture of the air inlet end of the fine hole 334 is larger than the aperture of the air outlet end, which is used to blow air toward the grinding position through the fine holes 334 to cool the grinding position and blow the debris generated by grinding off the plow blade; a plurality of arc-shaped windward plates are fixedly mounted on the rotating block 332, so that the rotating block 332 rotates with the wind when blown by the wind, thereby driving the bristles 333 to clean the surface of the workpiece; the air inlet side of the arc-shaped windward plate is preferably serrated to reduce wind noise.

[0032] The telescopic tube 34 consists of a fixed section 341, a movable section 342 slidably installed on the fixed section 341, and an elastic member 343 connecting the movable section 342 and the fixed section 341. When the fan 31 is turned off, the elastic member 343 drives the movable section 342 to retract toward the fixed section 341, thereby driving the air nozzle to retract; a limit member can be installed on one side of the forward direction of the shell 331, which is used to abut against the slide plate 16 to avoid interfering with the grinding rod 11 and limit the displacement of the cleaning member 33.

[0033] The wiping member 35 comprises: a storage box 351, the aperture of the air outlet of the storage box 351 is smaller than the aperture of the air inlet, a wiping box 352 movably mounted on the bottom of the storage box 351, a smearing roller 353 rotatably mounted on the wiping box 352, and a second spring 354 fixedly mounted between the wiping box 352 and the storage box 351; the storage box 351 stores anti-rust oil inside, and a plurality of oil outlet holes are opened on the bottom plate of the storage box 351, each of the oil outlet holes is connected to an oil outlet pipe 3511, and the bottom of the oil outlet pipe 3511 is connected to a telescopic hose 35 12; A seal 3521 is provided on the top of the wiping box 352. The cross section of the seal 3521 is T-shaped. The seal 3521 is slidably installed in the oil outlet pipe 3511, the telescopic hose 3512, and the oil outlet hole. In the natural state, the T-shape presses the oil outlet hole. When the coating roller 353 contacts the surface of the plow blade, the coating roller 353 is squeezed and moves upward. At this time, the seal 3521 is separated from the oil outlet hole, and the anti-rust oil flows out from the gap between the oil outlet hole and the seal 3521, and flows to the surface of the coating roller 353 through the oil outlet pipe 3511. The storage box 351 is composed of a pressurized chamber 3514 at the top, a storage chamber 3515 at the bottom, and a pressurized sheet 3516 between the pressurized chamber 3514 and the storage chamber 3515; the pressurized chamber 3514 is connected to the telescopic tube 34, and the pressurized sheet 3516 is made of elastic material or slidably installed in the pressurized chamber 3514; thus, when the fan 31 is started, the cleaning member 33 can be driven to move in the direction of the plow blade. During the movement, the wind force drives the rotating block 332 to rotate, thereby driving the bristles 333 to brush off the large particles of debris remaining on the surface of the plow blade. At the same time, the compressed airflow blows toward the plow blade from the fine holes 334, thereby blowing off Small particles of impurities on the surface of the plow blade after grinding; at the same time, the cleaning member 33 drives the wiping member 35 to move toward the plow blade. When the coating roller 353 contacts the plow blade, it slides upward due to extrusion, causing the anti-rust oil to flow to the surface of the coating roller 353, thereby wiping the anti-rust oil on the surface of the plow blade; at the same time, when the air flow passes through the storage box 351, the pressure of the boost chamber 3514 is increased, and then the storage chamber 3515 is pressurized through the boost sheet 3516, so that the storage chamber 3515 maintains a large pressure, which can ensure the amount of oil flowing to the surface of the coating roller 353 when the anti-rust liquid in the storage chamber 3515 is insufficient, and the pressurization can also make the anti-rust oil spray onto the coating roller 353.

[0034] The control unit adjusts the grinding method according to the coulter type as follows: A training model for grinding a plow blade is constructed, and the training model at least includes: plow blade shape extraction and grinding path planning; wherein the grinding path planning includes: lateral movement path planning, longitudinal movement path planning, vertical movement path planning, and grinding angle planning; the lateral movement path and the longitudinal movement path are adjusted by the fixed component 2; the vertical movement path and the grinding angle are adjusted by the grinding component 1; during the model training process, the actually executed path is compared with the expected path, and the difference between the two is calculated, and the difference is input into the model as a feedback signal, and the parameters of the model are adjusted according to the feedback signal, so that the model can gradually optimize the path planning; for example: if the actually executed path is longer than the expected path, the model can adjust the parameters to try to find a shorter path.

[0035] The training model is trained in the database using a three-dimensional simulation method. The above training includes: using three-dimensional modeling software to establish a digital model of the plow blade, and using three-dimensional motion simulation software to establish a model of the grinding equipment, and importing the plow blade model into the grinding equipment model to simulate the grinding process; introducing physical factors such as friction, material strength, wear rate, etc. into the simulation training to ensure that the simulation process can be as close as possible to the grinding conditions in the real environment, and optimizing the grinding path and equipment parameters according to the grinding results; three-dimensional modeling software such as: ANSYS, Abaqus, etc.

[0036] After the simulation training is completed, the standard coulter is put into actual training; the execution result of each training is recorded, and the wear degree of the grinding rod 11 is recorded.

[0037] When the execution result is correct, it is marked as correct; when the execution result is wrong, it is marked as wrong and the deviation is entered.

[0038] The input deviation includes: classifying and counting the error types, and sorting the error types by the number of occurrences and the frequency of occurrence; setting the threshold interval of the number of errors, when the number of errors of a specific type is greater than the threshold interval, the frequency is prioritized for sorting; when the number of errors of a specific type is less than the threshold interval, the number of errors is prioritized for sorting; the threshold interval is related to the total number of errors; introducing error spatial distribution analysis to help identify errors that are prone to occur in specific areas or angles. After the model training is completed, the corresponding plow blade is polished according to the training model, and the polishing information is recorded.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art.
