Description

Technical Field

[0001] The invention relates to the technical field of paddy field slurry mixer component processing technology, in particular to an automatic drilling device for a paddy field slurry mixer component. Background Art

[0002] Paddy field mud mixer is a kind of agricultural machinery specially used for paddy field cultivation. It is mainly used to stir and mix soil, fully blend water and mud to form a soft mud state suitable for transplanting rice. Paddy field mud mixer is mainly composed of mud stirring system, transmission system and operating system, among which the mud stirring blade is the main operating part of the mud stirring system. Fig.10 As shown, the slurry stirring blade is composed of a square section and a corrugated section, so that the slurry stirring blade can fully turn over the soil when in use. A mounting hole is opened in the middle of the square section, and the slurry stirring blade can be fixed on the rotating shaft by bolts through the mounting hole.

[0003] When drilling holes in the agitator blade, a fixture is usually used to clamp and fix the square section of the agitator blade, and then the agitator blade is drilled by a drilling device. Finally, the agitator blade after the drilling process is completed is taken out to complete the drilling process of the agitator blade.

[0004] However, the above-mentioned agitator blade drilling process has the following problems: 1. Since only the square section of the agitator blade is clamped and fixed, the clamping force is insufficient. Therefore, the stability of the agitator blade clamping cannot be ensured during the drilling process, which may easily lead to a decrease in the drilling quality of the agitator blade; 2. When the agitator blade is drilled, the agitator blade may vibrate or swing under the action of the cutting force, and the farther the part of the agitator blade is from the drilling position, the greater the amplitude of the vibration or swing, which may easily cause the waveform section of the agitator blade to deform, resulting in a decrease in the use effect of the agitator blade after the drilling process is completed.

[0034] The present invention can locate the drilling position of the agitator blade, increase the drilling accuracy of the agitator blade, and the present invention can clamp the agitator blade at multiple points, thereby increasing the stability of the clamping and fixing of the agitator blade, ensuring the drilling quality of the agitator blade. At the same time, the present invention can also protect the arc structure of the agitator blade, thereby preventing the arc structure of the agitator blade from deforming, thereby ensuring the use effect of the agitator blade after the drilling process is completed.

[0035] Specifically, first place the stirring blade in the clamping unit 3, and place the square section of the stirring blade on the positioning unit 5, then control the positioning unit 5 to adjust the square section of the stirring blade front and back, and then control the clamping unit 3 to clamp and fix the stirring blade at multiple points, so that the clamping unit 3 can stably clamp the stirring blade, and at the same time the clamping unit 3 can drive the protective unit 4 to support the corrugated section of the stirring blade, then control the drilling unit 2 to drill the square section of the stirring blade, and finally control the clamping unit 3 to release the stirring blade and take the stirring blade out of the clamping unit 3 to complete the drilling of the stirring blade.

[0036] See also Figure 1-Figure 3 The drilling unit 2 includes an L-shaped plate 21 fixedly installed on the left side of the upper end of the base 1, and a drilling member 22 is fixedly installed on the middle part of the lower end of the horizontal section of the L-shaped plate 21; the positioning unit 5 includes two front-to-back symmetrically arranged matching blocks 54 slidably installed on the right side of the vertical section of the L-shaped plate 21, and the ends of the two matching blocks 54 away from each other are both set to a trapezoidal structure, and a top extension spring 55 is connected between the matching block 54 and the vertical section of the L-shaped plate 21, and the sides of the two matching blocks 54 close to each other are fixedly installed with a positioning plate 57 through a square spring rod 56.

[0037] See also Figure 2 and Figure 3 The positioning unit 5 also includes two symmetrically arranged leveling plates 51 that are slidably installed up and down on the right side of the vertical section of the L-shaped plate 21, and the leveling plates 51 are located on the opposite sides of the two positioning plates 57. A second synchronization member 52 is commonly installed between the two leveling plates 51 and the L-shaped plate 21. Two U-shaped plates 53 that are symmetrically arranged front and back are fixedly installed on the sides of the two leveling plates 51 that are away from each other. The U-shaped plate 53 is away from the vertical section of the leveling plate 51 and is in contact with the inclined surface of the trapezoidal structure of the matching block 54. The U-shaped plate 53 is used to drive the two matching blocks 54 to move in a direction close to each other.

[0038] It should be noted that the drilling component 22 in the present invention uses the existing technology to drill holes on the agitator blade, and the drilling component 22 includes a control component, an adjusting screw and a drill bit, wherein the control component is slidably installed left and right on the lower end of the horizontal section of the L-shaped plate 21, the control component is connected to the adjusting screw by threaded matching, and the adjusting screw and the horizontal section of the L-shaped plate 21 are rotatably connected, and the drill bit is detachably installed at the lower end of the control component. When it is necessary to drill a hole on the agitator blade, first select the corresponding drill bit according to the drilling size of the agitator blade and install it on the lower end of the control component, and then control the adjustment screw to rotate according to the drilling position of the agitator blade and the distance between the vertical section of the L-shaped plate 21 to adjust the position of the control component, and finally start the control component to drive the drill bit to rotate and drive the drill bit to move downward to achieve drilling of the agitator blade.

[0039] See also Figure 2 and Figure 3 It should be noted that the No. 2 synchronous component 52 in the present invention includes a No. 2 motor and a No. 2 synchronous screw. The No. 2 synchronous screw is provided with two threaded segments arranged up and down and with opposite thread directions. The two leveling plates 51 are connected to the corresponding threaded segments on the No. 2 synchronous screw by threaded matching, and the No. 2 synchronous screw is rotatably connected to the L-shaped plate 21. The upper end of the No. 2 synchronous screw is connected to the output shaft of the No. 2 motor, and the No. 2 motor is installed in the L-shaped plate 21. The No. 2 synchronous screw is driven to rotate by controlling the No. 2 motor to realize the synchronous position adjustment of the two leveling plates 51.

[0040] The drilling unit 2 is used for drilling holes in the agitator blade, and the positioning unit 5 is used for adjusting the square section of the agitator blade to the center front and back. At the same time, the positioning unit 5 can also arrange the square section of the agitator blade horizontally to further increase the drilling accuracy of the agitator blade. Specifically, when the agitator blade is placed in the clamping unit 3, the left end of the square section of the agitator blade is first pressed against the right side of the vertical section of the L-shaped plate 21, and the square section of the agitator blade is placed between the two leveling plates 51, and then the No. 2 synchronization member 52 is controlled to drive the two leveling plates 51 to move in a direction close to each other, and the leveling plate 51 drives the U-shaped plate 53 connected to it to move synchronously, and the leveling plate 51 can first pass through the trapezoidal structure of the U-shaped plate 53 and the matching block 54. The inclined surfaces cooperate so that the matching block 54 is subjected to a driving force directed toward the leveling plate 51. Under the action of the driving force, the two positioning plates 57 move toward each other and compress the extension spring 55. When the two positioning plates 57 are both fitted to the front and rear ends of the square section of the agitator blade and compress the square spring rod 56, under the elastic action of the corresponding square spring rod 56, the two positioning plates 57 move synchronously with the leveling plate 51 to align the square section of the agitator blade and the drilling member 22 front and back in the center. Then the two leveling plates 51 are clamped on the upper and lower sides of the square section of the agitator blade to arrange the agitator blade horizontally. When the clamping unit 3 completely clamps and fixes the agitator blade, the drilling member 22 is controlled to perform drilling processing on the agitator blade.

[0041] When the drilling process of the agitator blade is completed, first control the No. 2 synchronization component 52 to drive the two leveling plates 51 to move away from each other to the initial position. As the U-shaped plate 53 moves away, the matching block 54 is reset under the action of the rebound force of the extension spring 55 and drives the positioning plate 57 to return to the initial position through the square spring rod 56, so that the agitator blade after the drilling process can be taken out.

[0042] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 The clamping unit 3 includes a back plate 31 fixedly mounted on the rear side of the middle part of the upper end of the base 1, a plurality of transmission mechanisms 32 evenly arranged left and right are installed at the front end of the back plate 31, two clamping rods 33 symmetrically arranged up and down and having an L-shaped structure are installed on the transmission mechanism 32, the transmission mechanism 32 is used to drive its corresponding two clamping rods 33 to clamp the stirring blade, two symmetrically arranged synchronization rods 34 are commonly installed at the rear ends of the plurality of transmission mechanisms 32, and the synchronization rods 34 are distributed on the rear side of the back plate 31, a synchronization piece 35 is commonly installed between the two synchronization rods 34 and the back plate 31, and a locking mechanism 36 for locking the clamping rod 33 is installed at the front end of the back plate 31.

[0043] It should be noted that the No. 1 synchronous component 35 in the present invention includes a No. 1 motor, a No. 1 synchronous screw and a fixed block. The No. 1 synchronous screw has the same structure as the No. 2 synchronous screw, wherein the two synchronous rods 34 are connected to the corresponding threaded segments on the No. 1 synchronous screw by threaded cooperation, and the middle part of the No. 1 synchronous screw is rotatably connected to the fixed block fixedly installed on the rear end of the back plate 31, the upper end of the No. 1 synchronous screw is connected to the output shaft of the No. 1 motor, and the No. 1 motor is fixedly connected to the back plate 31. The No. 1 motor is controlled to drive the No. 1 synchronous screw to rotate, so as to realize the synchronous position adjustment of the two synchronous rods 34.

[0044] The clamping unit 3 adopts a multi-point clamping method to stably clamp and fix the agitator blade; specifically, the agitator blade is first placed between the horizontal sections of the two clamping rods 33 arranged vertically. When the two leveling plates 51 are clamped on the upper and lower sides of the square section of the agitator blade, the first synchronization member 35 is controlled to drive the two synchronization rods 34 to move toward each other, so that the synchronization rod 34 drives the two clamping rods 33 arranged vertically through multiple transmission mechanisms 32 to be elastically clamped on the upper and lower sides of the agitator blade. When the two synchronization rods 34 move toward each other to the limit position, The locking mechanism 36 can lock the position of the clamping rod 33, so that the two clamping rods 33 arranged above and below clamp and fix the stirring blade, and there are multiple clamping rods 33, so that the clamping rod 33 can clamp the wavy section and the square section of the stirring blade at multiple points at the same time. After the drilling process of the stirring blade is completed, the No. 1 synchronization member 35 is controlled to drive the two synchronization rods 34 to move to the initial position in the direction of approaching each other. At the same time, the locking mechanism 36 can release the lock of the clamping rod 33, so that the synchronization rod 34 finally drives the clamping rod 33 to release the stirring blade through the transmission mechanism 32.

[0045] See also Figure 4 , Figure 5 and Figure 6 The transmission mechanism 32 includes two transmission plates 321 symmetrically arranged up and down and slidably installed on the front end of the back plate 31. A transmission block 322 is fixedly installed on the rear end of the transmission plate 321. The rear end of the transmission block 322 passes through the back plate 31 and is fixedly connected to its corresponding synchronization rod 34. The front ends of the two transmission plates 321 are both slidably installed with connecting plates 324 through guide springs 323, and the connecting plates 324 are fixedly installed on the end of the vertical section of the corresponding clamping rod 33 away from the middle of the back plate 31.

[0046] The transmission mechanism 32 is used to drive the two corresponding clamping rods 33 to move synchronously; specifically, when the two synchronization rods 34 move synchronously, the synchronization rod 34 drives the two upper and lower transmission plates 321 to move synchronously through the transmission block 322. When the two transmission plates 321 move synchronously in the direction of approaching each other, the transmission plate 321 drives the corresponding two upper and lower clamping rods 33 to move in the direction of approaching each other through the connecting plate 324. When the clamping rod 33 clamps the stirring blade, the guide spring 323 is in a compressed state. The guide spring 323 is used to buffer the clamping of the stirring blade by the clamping rod 33, so that the clamping rod 33 can clamp the waveform section of the stirring blade, thereby realizing multi-point clamping of the stirring blade.

[0047] See also Figure 4-Figure 7 The locking mechanism 36 includes a locking plate 361 which is slidably mounted on the front end of the back plate 31 and is located on the left side of the two clamping rods 33 arranged vertically. A return spring 362 is connected between the locking plate 361 and the back plate 31. Round rods 363 are fixedly mounted on the upper and lower ends of the opposite sides of the two adjacent locking plates 361. A plurality of locking holes 364 arranged evenly vertically are opened on the locking plate 361 at positions corresponding to the clamping rods 33. A lock for cooperating with the corresponding locking holes 364 is fixedly mounted on the left side of the vertical section of the clamping rod 33. The fixed column 331; a matching rod 311 is installed in the middle of the left end of the rear side of the back plate 31 for sliding left and right through a return spring, and the upper and lower sides of the right end of the matching rod 311 are set as inclined surfaces, and the inclined surface of the matching rod 311 is used to cooperate with the synchronization rod 34 to drive the matching rod 311 to move to the left, and a changing piece 365 is connected between the leftmost locking plate 361 and the matching rod 311, and the changing piece 365 is connected to the back plate 31, and the changing piece 365 is used to drive the leftmost locking plate 361 to move in a direction opposite to the moving direction of the matching rod 311.

[0048] See also Figure 4-Figure 7It should be noted that the direction-changing member 365 of the present invention includes a direction-changing rod 3651 distributed in the middle of the left side of the back plate 31, the front and rear ends of the direction-changing rod 3651 are both set as elastic telescopic structures, and the direction-changing rod 3651 and the back plate 31 are arranged in the middle of the front and rear, the middle of the right end of the direction-changing rod 3651 is hinged with a fixed rod 3652 fixedly installed on the left end of the back plate 31, the front end of the direction-changing rod 3651 is hinged with a transmission rod 3653, the rear end of the direction-changing rod 3651 is hinged with a square rod 3654, and the transmission rod 3653 and the square rod 3654 are initially connected to the direction-changing rod 3651. It is arranged vertically on a horizontal plane, wherein the right end of the transmission rod 3653 is fixedly installed on the left end of the leftmost locking plate 361, and the right end of the square rod 3654 is fixedly connected to the matching rod 311. When the matching rod 311 moves, the matching rod 311 drives the square rod 3654 to move synchronously. The movement of the square rod 3654 causes the direction-changing rod 3651 to rotate with its hinge with the fixed rod 3652 as the rotation point, and then the direction-changing rod 3651 drives the leftmost locking plate 361 to move in the direction opposite to the moving direction of the matching rod 311 through the transmission rod 3653.

[0049] The locking mechanism 36 is used to lock the position of the clamping rod 33 so that the clamping rod 33 rigidly clamps the stirring blade. Specifically, during the movement of the two synchronization rods 34 toward each other, the synchronization rod 34 drives the two transmission plates 321 arranged up and down to move synchronously through the transmission block 322. The transmission plate 321 drives the corresponding two clamping rods 33 arranged up and down to move toward each other through the connecting plate 324. When the clamping rod 33 clamps the stirring blade, the guide spring 323 is in a compressed state. After the clamping rod 33 clamps the stirring blade, the synchronization rod 34 continues to move. The clamping rod 33 is affected by the stirring blade. The plate is blocked but the position remains unchanged, the transmission plate 321 moves relative to the clamping rod 33 toward the pulping blade (there is relative movement between the two), and the guide spring 323 is further compressed and contracted. When the synchronization rod 34 contacts the inclined surface of the matching rod 311 and continues to move, the contraction amount of the guide spring 323 gradually increases, and the inclined surfaces of the synchronization rod 34 and the matching rod 311 cooperate to give the matching rod 311 a driving force to move left, the return spring is compressed and contracted, and the matching rod 311 that moves left pushes the leftmost locking plate 361 to move right through the changing member 365, and under the action of the round rod 363, all the locking plates 361 move right synchronously, so that The locking post 331 can be inserted into the corresponding locking hole 364, thereby locking the clamping rod 33, so that the clamping rod 33 rigidly clamps the paddle blade. When the two synchronous rods 34 move in the direction away from each other, the transmission plate 321 moves synchronously therewith. Under the rebound force of the return spring, the matching rod 311 moves to the right, and the locking plate 361 moves to the left under the rebound force of the return spring 362. However, before the inclined surfaces of the synchronous rod 34 and the matching rod 311 are completely separated, the clamping rod 33 is restricted by the locking plate 361 and the locking hole 364 and does not change position, that is, the transmission plate 321 and the clamping rod 33 The locking pin 331 is in the locking position when the locking cam 361 is in the locking position, and the locking pin 331 is in the locking position when the locking cam 361 is in the locking position. Figure 6 ), the transmission plate 321 continues to move, which will drive the clamping rod 33 to move, and the clamping rod 33 is separated from the stirring blade, releasing the clamping.

[0050] See also Figure 1 , Figure 4 and Figure 8The protection unit 4 includes two sliding plates 41 that are symmetrically arranged and L-shaped and are installed on the right end of the front side of the back plate 31 for upward and downward sliding. The rear end of the sliding plate 41 passes through the back plate 31 and is fixedly connected to the corresponding synchronization rod 34. A plurality of protection rods 42 are distributed on opposite sides of the transverse sections of the two sliding plates 41. A fitting mechanism 43 for fitting the protection rod 42 to the stirring blade is connected between the protection rod 42 and its corresponding sliding plate 41, and the fitting mechanism 43 is located between two adjacent clamping rods 33 on the left and right.

[0051] The protection unit 4 is used to protect the arc structure of the stirring blade; specifically, when the two synchronization rods 34 move toward each other, the synchronization rod 34 can drive the two sliding plates 41 to move toward each other, so that the sliding plate 41 drives the protection rod 42 to fit on the stirring blade through the fitting mechanism 43, so that the protection rod 42 protects the arc structure of the stirring blade, thereby preventing the arc structure of the stirring blade from deformation, thereby ensuring the use effect of the stirring blade after the drilling process is completed.

[0052] See also Figure 4 , Figure 8 and Fig. 9 The fitting mechanism 43 includes a clamping spring rod 431 that is slidably installed on the opposite sides of the transverse sections of the two sliding plates 41 and is located between two adjacent clamping rods 33. The clamping spring rods 431 on the upper and lower sliding plates 41 are staggered left and right, and the ends of the upper and lower clamping spring rods 431 that are close to each other are rotatably installed with a rotating rod 432, and a torsion spring is connected between the rotating rod 432 and the clamping spring rod 431, and the end of the rotating rod 432 away from the clamping spring rod 431 is fixedly connected to the middle part of the corresponding protective rod 42.

[0053] like Fig.10 As shown, it should be noted that when the agitator blade is placed with the axis of the mounting hole vertical, the front and rear end faces and the upper and lower end faces of the agitator blade waveform section are non-straight surfaces, that is, the agitator blade waveform section is a three-dimensional waveform structure in the front and back and up and down directions.

[0054] The fitting mechanism 43 is used to fit the protective rod 42 to the stirring blade; specifically, when the two sliding plates 41 move toward each other, the sliding plate 41 drives the protective rod 42 to move synchronously by pressing against the spring rod 431. After the protective rod 42 contacts the corrugated section of the stirring blade, the sliding plate 41 continues to move. The protective rod 42, which is installed in a rotating manner through the rotating rod 432, adaptively adapts to the upper and lower end surface shapes of the corrugated section of the stirring blade. Finally, the protective rod 42 can be tightly attached to the corrugated section of the stirring blade, and the upper and lower limit positions of the corrugated section of the stirring blade are implemented, thereby further reducing the vibration generated during the drilling process of the stirring blade and preventing the corrugated section of the stirring blade from being deformed.

[0055] See also Figure 4, Figure 8 and Fig. 9 A plurality of circular grooves 434 evenly arranged up and down are provided at the front end of the tightening spring rod 431, and a limiting spring rod 433 is slidably installed at the front end of the sliding plate 41 corresponding to the position of the tightening spring rod 431, and the limiting spring rod 433 is used to cooperate with the circular groove 434 to lock the tightening spring rod 431, and a push rod 435 is fixedly installed at the front ends of the plurality of limiting spring rods 433 arranged on the left and right; a vertical plate 11 is fixedly installed at the position corresponding to the tightening spring rod 431 on the front side of the upper end of the base 1, and a trapezoidal block 12 is installed on the rear side of the upper end of the vertical plate 11, and the inclined surface of the trapezoidal block 12 is set to face backwards, and the trapezoidal block 12 is used to cooperate with the push rod 435 to drive the limiting spring rod 433 to move backward.

[0056] During the movement of the push rod 435 driven by the two sliding plates 41 through the limit spring rod 433, when the push rod 435 contacts the inclined surface of the trapezoidal block 12 and continues to move, the push rod 435 moves backward under the action of the inclined surface of the trapezoidal block 12, so that the push rod 435 drives its corresponding limit spring rod 433 to move backward and insert into the corresponding circular groove 434 on the corresponding clamping spring rod 431, thereby locking the clamping spring rod 431 and further increasing the protective effect of the protective rod 42 on the corrugated section of the pulping blade.

[0057] See also Figure 1 and Figure 2 A locking rod 571 is fixedly installed on the right side of the lower end of the positioning plate 57, and a square plate 412 is fixedly installed on the left end of the horizontal section of the lower sliding plate 41 through a connecting rod 411. A plurality of circular holes 413 evenly arranged front and back are opened on the upper end of the square plate 412. The circular holes 413 are used to cooperate with the locking rod 571 to lock the positioning plate 57.

[0058] When the two sliding plates 41 move toward each other, the lower sliding plate 41 drives the square plate 412 to move upward through the connecting rod 411, so that the locking rod 571 can be inserted into the circular hole 413 to lock the positioning plate 57, further preventing the agitator blade from deviating when drilling the agitator blade.

[0059] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
