[0033] The automatic rubber tapping equipment and control method disclosed in the present invention are as follows: a guide rail 1 is arranged around a rubber tree 4; and then a vehicle-mounted frame mechanism 2 is connected to the guide rail 1, so that the vehicle-mounted frame mechanism 2 moves around the rubber tree 4 under the drive of a driving member 21; a transmission assembly 23 is arranged between the driving member 21 and a knife retracting and releasing mechanism 33; the transmission assembly 23 includes a step-by-step structure 22 and a locking tooth 232; when the knife holder mechanism 3 is located at the starting position, the driving member 21 is used to drive the step-by-step structure 22 to drive the knife holder mechanism 3 to descend a specified distance, and drive the knife retracting and releasing mechanism 33 to make the rubber tapping blade 34 abut against the rubber tree 4; when the rubber tapping blade 34 abuts against the rubber tree 4, the driving member 21 is used to drive the knife holder mechanism 3 to move along a spiral track relative to the rubber tree 4 through the step-by-step structure 22 to perform a rubber tapping operation; thereby, rubber tapping is avoided while the rubber tapping knife holder is descending, and a step-by-step operation is performed.

[0034] Specifically, the driving member 21 is also used to drive the vehicle-mounted frame mechanism 2 to move between the starting position and the end position along the guide rail 1; the vehicle-mounted frame mechanism 2 is also used to be connected to the knife holder mechanism 3. When the driving member 21 drives the vehicle-mounted frame mechanism 2 to move along the guide rail 1, it also drives the knife holder mechanism 3 to move relative to the rubber tree 4; the knife holder mechanism 3 includes a mounting frame 31 and a screw rod 32, the screw rod 32 and the knife retracting mechanism 33 are connected to the mounting frame 31, and the screw rod 32 cooperates with the driving member 21 to drive the mounting frame 31 to move up and down along the screw rod 32; the knife retracting mechanism 33 is used to install a rubber tapping blade 34, and the knife retracting mechanism 33 is connected to the driving member 21 to move relative to the mounting frame 31 under the drive of the driving member 21; when the knife holder mechanism 3 is in the starting position, the driving member 21 is used to drive the step-by-step Structure 22 drives knife rest mechanism 3 to descend a specified distance, and knife retracting mechanism 33, under the drive of driving member 21, makes rubber tapping blade 34 abut against rubber tree 4, and guide rail 1 and screw rod 32 are matched by driving member 21, so that mounting frame 31 and vehicle-mounted frame mechanism 2 are synchronously moved, so that knife rest mechanism 3 moves along spiral track relative to rubber tree 4, so that rubber tapping blade 34 is tapped along spiral track, when knife rest mechanism 2 moves to terminal position, knife retracting mechanism 33, under the reverse drive of driving member 21, makes rubber tapping blade 34 away from rubber tree 4, and guide rail 1 and screw rod 32 are matched by driving member 21, so that mounting frame 31 and vehicle-mounted frame mechanism 2 are synchronously reversely moved, so that knife rest mechanism 3 moves along spiral track relative to rubber tree 4, and knife rest mechanism 3 moves to starting position. Wherein, spiral track refers to the track formed by the arc superposition within 180 ° that the rubber tapping knife actually cuts, and spiral track is the track that meets national standard regulations. Wherein, it should be noted that the starting position in this application can be the left side of the spiral track or the right side of the track. The specific selection is based on the actual cutting situation.

[0035] The present invention connects the vehicle-mounted frame mechanism 2 and the knife frame mechanism 3 through a driving member 21, and the driving member 21 is used to drive the vehicle-mounted frame mechanism 2 to move between the starting position and the end position of the guide rail 1; when the driving member 21 drives the vehicle-mounted frame mechanism 2 to move along the guide rail 1, it drives the knife frame mechanism 3 to move synchronously relative to the rubber tree 4, so that the knife frame mechanism 3 moves along a spiral track relative to the rubber tree 4; the driving member 21 drives the knife retracting and releasing mechanism 33, so that the rubber tapping blade 34 abuts against the rubber tree 4, and after the rubber tapping blade 34 abuts against the rubber tree 4, the knife frame mechanism 3 is driven to move along a spiral track to realize the rubber tapping operation on the rubber tree 4. Thereby, the number of driving members 21 is reduced, and the driving of the entire machine is realized by one driving member 21, and the corresponding control system can also be simplified, saving manpower, financial resources and electricity.

[0036] In the disclosed embodiment, the automatic rubber tapping equipment is a device for cutting rubber trees 4 to obtain rubber, wherein the guide rail 1 is used to connect the rubber trees 4, and the guide rail 1 can be a deformable structure, so that it can fit the shape of the rubber tree 4 and fit on the rubber tree 4, and the guide rail 1 is connected to the vehicle frame mechanism 2 by sliding. Specifically, the vehicle frame mechanism 2 includes an upper vehicle frame 26 and a lower vehicle frame 27, and correspondingly, the guide rail 1 also includes an upper guide rail and a lower guide rail, and the vehicle frame mechanism 2 is connected to the upper guide rail through the upper vehicle frame 26, and is connected to the lower vehicle frame through the lower vehicle frame The frame 27 is connected to the lower rail, and the upper frame 26 and the lower frame 27 are driven by the driving member 21 to move relative to the rail, so as to realize the movement around the rubber tree 4; specifically, the movement interval is between the starting position and the end position, wherein the starting position refers to the position where the rubber tapping blade 34 starts to tap rubber, and the end position refers to the position where the rubber tapping blade 34 ends tapping rubber, and specifically, through the spiral trajectory of rubber tapping, a Hall switch is provided at the starting position and the end position, and the starting position or the end position is determined after the Hall switch is sensed. Among them, the knife holder mechanism 3 is arranged between the upper frame 26 and the lower frame 27, specifically, the upper frame 26 and the lower frame 27 are connected by a bracket, and the knife holder mechanism 3 is connected to the bracket, so as to improve the structural stability. The knife holder mechanism 3 is used to install the rubber tapping blade 34 and control the position of the rubber tapping blade 34; the specific height is determined by the specific situation. When the driving member 21 drives the vehicle frame mechanism 2 to move, the vehicle frame mechanism 2 drives the knife holder mechanism 3 to move synchronously. At the same time, the driving member 21 drives the screw rod 32 to rotate through the connection with the screw rod 32, thereby driving the mounting frame 31 in the vehicle frame mechanism 2 to move up and down along the screw rod 32; by driving the vehicle frame mechanism 2 and the screw rod 32, the rubber tapping tool is tapped along a spiral trajectory, and the spiral trajectory refers to the trajectory of rubber tapping, that is, the trajectory corresponding to the rubber tapping blade 34 during the rubber tapping process. Specifically, the mounting frame 31 is also connected to a knife retracting and releasing mechanism 33, which is connected to the driving member 21, and is driven by the driving member 21 to control the rubber tapping blade 34 to abut against the rubber tree 4. The spiral trajectory is formed by the circular motion of the vehicle frame mechanism 2 in the horizontal direction and the linear motion of the knife holder mechanism 3 in the vertical direction.

[0037] The specific rubber tapping process is as follows: when the vehicle-mounted frame mechanism 2 is located at the starting position, the rubber tapping instruction is obtained, the driving member 21 is reversed, and the knife retracting and releasing mechanism 33 is controlled to make the rubber tapping blade 34 abut against the rubber tree 4, and then the driving member 21 cooperates with the guide rail 1 and the screw rod 32 to make the mounting frame 31 and the vehicle-mounted frame mechanism 2 move synchronously, so that the knife holder mechanism 3 moves along a spiral trajectory relative to the rubber tree 4, so that the rubber tapping blade 34 taps rubber along the spiral trajectory, and when the vehicle-mounted frame mechanism 2 moves to the terminal position, one rubber tapping operation is completed; when the knife holder mechanism 2 moves to the terminal position, the knife retracting and releasing mechanism 33 is driven in the reverse direction by the driving member 21, so that the rubber tapping blade 34 is away from the rubber tree 4, and when the driving member 21 cooperates with the guide rail 1 and the screw rod 32, the mounting frame 31 and the vehicle-mounted frame mechanism 2 are synchronously moved in the opposite direction, so that the knife holder mechanism 3 moves in the opposite direction along the spiral trajectory relative to the rubber tree 4, until the vehicle-mounted frame mechanism 2 moves to the starting position, the rubber tapping mechanism is returned, and the next rubber tapping can be carried out.

[0038] The rubber tapping mechanism is controlled by a motor, which reduces the cost of the rubber tapping mechanism, improves the uniformity of control, and reduces the difficulty of control.

[0039] Figure 4 The schematic diagram of the structure of the automatic rubber tapping equipment according to the embodiment of the present disclosure is shown. Figure 4 ; Figure 5 The schematic diagram of the structure of the automatic rubber tapping equipment according to the embodiment of the present disclosure is shown. Figure 5 ; Figure 6 The schematic diagram of the structure of the automatic rubber tapping equipment according to the embodiment of the present disclosure is shown. Figure 6 ; Figure 7 The schematic diagram of the structure of the automatic rubber tapping equipment according to the embodiment of the present disclosure is shown. Figure 7 ; Please refer to Figure 4-Figure 7 ;

[0040] Specifically, the vehicle frame mechanism 2 includes a step-by-step structure 22, which is used to drive the vehicle frame mechanism 2 and the screw rod 32 in steps when the driving member 21 controls the knife retracting and releasing mechanism 33 to retract and release the knife, thereby avoiding the situation of retracting and releasing the knife while the knife is moving. At the same time, through the step-by-step structure 22, the knife holder mechanism 3 moves downward by a specified distance during the first step of the operation, thereby avoiding the situation of cutting rubber while moving downward. Specifically, the step-by-step structure 22 includes a step-by-step tooth 221 and a screw tooth 222, the step-by-step tooth 221 is connected to the driving member 21, the driving member 21 is used to drive the step-by-step tooth 221 to rotate, the step-by-step tooth 221 is formed with a groove portion 2211, and a first abutment 2212 is arranged in the groove portion 2211; the screw tooth 222 includes an embedded portion 2221, the embedded portion 2221 is accommodated in the groove portion 2211, and a second abutment 2222 is arranged on the embedded portion 2221, the second abutment 2222 is used to cooperate with the first abutment 2212, and the screw tooth 222 is connected to the screw 32; so a gap is formed between the embedded portion 2221 and the groove portion 2211, so that the second abutment 2222 can rotate in the groove portion 2211, and the shapes of the first abutment 2212 and the second abutment 2222 are not limited, and preferably, they can be key-shaped.

[0041] When the vehicle frame mechanism 2 is at the starting position, the driving member 21 rotates forward, and the driving member 21 can be a motor. The driving member 21 rotates forward, that is, the motor rotates forward, and the first abutting member 2212 rotates from the first side of the second abutting member 2222 to the second side. In the process from the first side to the second side, the screw rod teeth 222 and the stepping teeth 221 do not abut, so there is no power transmission, and the screw rod 32 connected to the screw rod teeth 222 does not rotate. Further, a transmission member 25 is provided between the driving member 21 and the guide rail 1, and the transmission member 25 is connected to the screw rod teeth 222. When the screw rod teeth 222 rotate, the vehicle frame mechanism 2 is driven to move; so when the screw rod teeth 222 do not rotate, the vehicle frame mechanism 2 does not move. That is, the knife holder mechanism 3 does not move, so that the knife retracting and releasing mechanism 33 can retract and release the knife. The step-by-step teeth 221 are connected to the knife retracting and releasing mechanism 33 in a transmission manner, and the knife retracting and releasing operation is completed in the process of the step-by-step teeth 221 moving from the first side to the second side. When the first abutting member 2212 abuts against the second side of the second abutting member 2222, the step-by-step teeth 221 drive the screw rod teeth 222 to rotate synchronously, thereby driving the screw rod 32 to rotate; the first side and the second side are in different directions; when the vehicle-mounted frame mechanism 2 is at the terminal position, the driving member 21 is reversed, and the first abutting member 2212 rotates from the second side of the second abutting member 2222 to abut against the first side, and from the second side to the first side. During the process of moving from the second side to the first side, the screw rod teeth 222 and the step teeth 221 do not abut, so there is no power transmission, the screw rod 32 connected to the screw rod teeth 222 does not rotate, and the vehicle-mounted frame mechanism 2 does not move, so that the knife retracting mechanism 33 can retract the knife; the knife retracting operation is completed during the process of the step teeth 221 moving from the second side to the first side. When the first abutment 2212 abuts against the first side of the second abutment 2222, the step teeth 221 drives the screw rod teeth 222 to rotate synchronously, thereby driving the screw rod teeth 222 to rotate synchronously, thereby driving the screw rod 32 to rotate, and the vehicle-mounted frame mechanism 2 moves. Among them, the idling time of the step teeth 221 is greater than the time of retracting the knife. Specifically, taking the process from the starting point to the end point as an example, the process of the step teeth 221 moving from the first side to the second side is the first step operation of the step structure. When the first abutment member 2212 abuts against the second side of the second abutment member 2222, the step teeth 221 drive the screw rod teeth 222 to rotate synchronously, thereby driving the screw rod 32 to rotate, which is the first step operation of the step structure; thereby the actions of retracting and releasing the knife, moving the knife holder downward, and tapping are stepped.

The knife rod 331 includes a knife head and a blade body. The knife head is used for connecting the rubber tapping blade 34, and the blade body is rotatably connected to the mounting frame 31. One end of the blade body is connected to the knife head, and the other end is elastically connected to the slider 332. When the slider is pulled, the knife head is ejected by the elastic member to Abutting against the rubber tree 4; specifically, a rack 334 is provided on the slider 332, and the connecting rod 333 abuts against the rack 334 through the slider teeth 337; a transmission assembly 23 is provided in the vehicle-mounted frame mechanism 2, and the transmission assembly 23 is a transmission assembly, and the retractable knife is used to connect the step teeth 221 and the connecting rod 333; when the first abutment member 2212 rotates from the first side of the second abutment member 2222 to abut the second side, the transmission assembly 23 drives the connecting rod 333 to rotate forward to drive the slider teeth to rotate a specified angle, and the displacement distance of the slider 332 can be controlled by controlling the rotation angle. The slider teeth cooperate with the rack 334 to drive the slider 332 to move from the first position to the second position, and the first elastic member 335 cooperates with the slider 332 to drive the knife bar 331 to rotate, so that the rubber tapping blade 34 connected to the knife bar 331 abuts against the rubber tree 4, and rubber tapping begins; when the first abutment member 2212 rotates from the second side of the second abutment member 2222 to abut the first side, the transmission assembly 23 drives the connecting rod 333 to reverse, so as to drive the slider teeth to rotate in the opposite direction by a specified angle, and the slider teeth cooperate with the rack 334 to drive the slider 332 to move from the second position to the first position, and the slider 332 pulls the first elastic member 335 to drive the knife bar 331 to rotate, so that the rubber tapping blade 34 connected to the knife bar 331 is away from the rubber tree 4, and the knife retracting operation is completed. A pawl 36 is connected to the slider 332, and a ratchet 35 is provided on the screw rod 32, and the pawl 36 cooperates with the ratchet 35; specifically, in the process of retracting and releasing the knife, that is, the process of the slider 332 moving from the first position to the second position, the pawl 36 moves the ratchet 35 to make the mounting frame 31 move a specified distance along the screw rod 32, specifically, to descend a specified distance, and the specified distance is the distance corresponding to one movement of the ratchet 35.

[0043] Specifically, the transmission assembly 23 includes a clutch tooth 231, a locking tooth 232 and a connecting tooth 233; the clutch tooth 231 is formed with a sector tooth 2311, and the clutch tooth 231 is used to cooperate with the step tooth 221; the clutch tooth 231 is formed with a clutch groove 2312; the locking tooth 232 is formed with a fixed boss 2321, and the locking tooth 232 is connected to the clutch tooth 231 through the fixed boss 2321 and the clutch groove 2312; the locking tooth 232 is used to drive the connecting tooth 233 to rotate The designated angle is driven to drive the slider teeth to rotate the designated angle; wherein the designated angle corresponds to a specific number of teeth, when the first abutment member 2212 rotates from the first side of the second abutment member 2222 to the second side, the step-by-step teeth 221 mesh with the first end of the sector-shaped teeth 2311, rotates to the second end of the sector-shaped teeth 2311, and the step-by-step teeth 221 separate from the clutch teeth 231, and the step-by-step teeth 221 cooperate with the sector-shaped teeth 2311 to drive the connecting teeth 233 to rotate the designated angle. The first end and the second end are at different positions, and are located at the two ends of the sector respectively. When the fixed boss 2321 is embedded in the clutch groove 2312, a buffer gap is formed between the fixed boss 2321 and the clutch groove 2312. When the first elastic member 335 is retracting or releasing the knife, the buffer gap is used to buffer the reaction force brought by the first elastic member 335, thereby preventing the first elastic member 335 from driving the connecting rod 333 to move. Specifically, the buffer gap is set so that the clutch tooth 231 is not affected by the locking tooth 232, and can mesh with the stepping tooth 233 with a smaller reset torque when combined, and the phenomenon of tooth jamming is not likely to occur, thereby reducing losses. Specifically, the size of the buffer gap corresponds to the space required for the clutch tooth 231 to rotate one tooth.

[0044] The clutch tooth 231 is provided with a second elastic member 2313, and a limiting column is formed in the vehicle-mounted frame mechanism 2, and the limiting column is used for the second elastic member 2313 to abut against; when the step-by-step tooth 221 is in a separated state from the clutch tooth 231, the second elastic member 2313 cooperates with the limiting column so that the sector tooth 2311 is always in abutment with the step-by-step tooth 221, that is, the sector tooth 2311 always has one side in abutment with the step-by-step tooth 221, but is not meshed; when the step-by-step tooth 221 changes its rotation direction, the sector tooth 2311 meshes with the step-by-step tooth 221 under the action of the second elastic member 2313; the second elastic member 2313 is a tension spring, and is formed with an abutting portion, and the abutting portion is used to abut against the limiting column to provide a reset force to the clutch tooth 231.

[0045] Fig.10 The schematic diagram of the structure of the automatic rubber tapping equipment according to the embodiment of the present disclosure is shown. Figure 10Specifically, the locking tooth 232 is further formed with a first locking arc 2322, and the connecting tooth 233 is formed with a second locking arc 2331; when the stepping tooth 221 is separated from the clutch tooth 231, the first locking arc 2322 is used to cooperate with the second locking arc 2331 to lock the connecting rod 333. Specifically, there are two first locking arcs 2322 and two second locking arcs 2331, which cooperate in the knife-retracting state and the knife-releasing state to lock the square rod. The transmission assembly 23 also includes a pressing plate 24; a cam 2323 is formed under the locking tooth 232; the pressing plate 24 is rotatably connected to the vehicle frame mechanism 2, one end of the pressing plate 24 abuts against the cam 2323, and the other end of the pressing plate 24 abuts against the screw tooth 222; when the locking tooth 232 rotates, the cam 2323 rotates, driving one end of the pressing plate 24 to move, so that the pressing plate 24 rotates relative to the vehicle frame mechanism 2 to press the screw tooth 222. Among them, the cam 2323 refers to a wheel with an irregular radius. When the cam 2323 rotates, it will rotate the pressing plate 24 in the first direction, thereby driving the end of the pressing plate 24 abutting against the screw 32, providing a pressure to the screw 32 to prevent the screw 32 from rotating. In the face of the reaction force brought by the first elastic member 335, the transmission assembly 23 can be in a locked state, thereby improving the stability and practical life of the product.

[0046] A specific embodiment is provided. After receiving the rubber tapping instruction, the motor of the rubber tapping mechanism disclosed in the present invention rotates forward. When the motor rotates forward, it drives the step structure 22 to rotate, and completes the knife retracting and releasing operation in the step state. After the step state ends, the step teeth 221 drive the screw rod teeth 222 to rotate synchronously, and the knife holder mechanism 3 moves along the spiral track.

[0047] When the motor reaches the end position, the motor reverses. When the motor reverses, it drives the step structure 22 to rotate, and the knife retracting operation is completed in the step state. After the step state ends, the step teeth 221 drive the screw rod teeth 222 to rotate synchronously, and the knife holder mechanism 3 returns to the starting point along the spiral trajectory to start the next cycle.

[0048] When the knife is retracted or released, the slider 332 cooperates with the ratchet 35 and the pawl 36 to lower the knife holder mechanism 3 to a specified distance, that is, the thickness of the rubber to be tapped.

[0050] In the present disclosure, a plurality of automatic rubber tapping equipment can be uniformly controlled through a control terminal, thereby realizing large-scale rubber tapping operations, replacing traditional manual operations and increasing industrial output.

[0051] The control terminal can be wirelessly connected to the rubber tapping equipment. Specifically, the control terminal can be wirelessly connected to the control module of the rubber tapping equipment, so as to send instructions to the rubber tapping equipment. Specifically, the rubber tapping instructions can include starting rubber tapping, ending rubber tapping, pausing, etc. When the rubber tapping equipment receives the rubber tapping instruction, it performs corresponding operations according to the rubber tapping instruction, thereby realizing the switching of different states of the rubber tapping operation.
