Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of rubber tapping machines, and particularly relates to a single-motor-driven tangent rubber tapping machine. BACKGROUND

[0002] Natural rubber is an important industrial raw material, which is obtained by tapping the bark and phloem of rubber trees to allow latex (glue) to flow out and collect in a latex bowl, and then further processed. The traditional method of tapping is manual tapping, but manual tapping is low in efficiency and requires high physical strength, and causes great damage to the body of the rubber tapping worker.

[0003] For a long time, people have been researching on using machines to replace manual tapping, for example, the Chinese invention with the publication number CN114402947A and the name of natural rubber intelligent bundling type tree-shaped automatic tapping machine and use method, which makes the combined motion of the tapping knife into spiral motion by combining the circular motion and linear motion of the two driving mechanisms along the fixed track to form a spiral motion track, so as to drive the tapping knife to cut a spiral incision on the rubber tree along the rubber tree trunk, and the latex flows out from the incision. However, this spiral track type tapping method is not easy to cut the bark of the rubber tree when cutting the bark of the rubber tree, because the motion track of the tapping knife does not coincide with the force direction of the tapping knife, and the cutting depth may not be enough when the force is uneven, which may even cut the bark and cause tree damage. In addition, the combined motion track formed by the double-motor drive has high control difficulty and poor reliability. For another example, the Chinese invention with the publication number CN115399214A and the name of a tangent rubber tapping machine and method adopts tangent rubber tapping to avoid the problems of the spiral rubber tapping, such as the motion track of the tapping knife not coinciding with the force direction of the tapping knife, high control difficulty of the combined motion track, and poor reliability. However, it still needs to use two motors to drive the motion of the tapping knife in the vertical direction and the tangent rubber tapping direction, which leads to a complex driving mechanism and reduces the stability of the rubber tapping machine in use. In addition, the production and maintenance cost of the double-motor-driven rubber tapping machine is also relatively high. SUMMARY

[0004] Therefore, the present application provides a single-motor-driven tangent rubber tapping machine, which solves the problems of the traditional spiral rubber tapping, such as the force direction of the tapping knife not coinciding, high control difficulty of the combined motion track, and poor reliability, as well as the problems of the double-motor-driven rubber tapping machine, such as the mechanism being complex, the stability being poor, and the production and maintenance cost being high.

[0023] Further, the second vertical spring exerts a vertical downward elastic force on the second vertical sliding seat through the sleeve pipe sleeved on the second vertical guide rod.

[0034] Further, the rubber tapping machine is further provided with a gas stimulation device for releasing stimulating gas to stimulate the rubber tree to produce more latex.

[0035] The cutting head is further provided with a chip blocking structure, which can push the cutting chips to the tapping direction while the tapping cutter is cutting the rubber.

[0036] Beneficial effects:

[0037] 1. The single-motor linear driving mechanism is used to drive the cutting head to move along a straight line oblique to the horizontal plane. The cutting head is provided with a tapping cutter. During the movement of the cutting head to the oblique upper side along the straight line oblique to the horizontal plane, the tapping cutter can tap the rubber and form a tapping surface oblique to the horizontal plane. When the cutting head moves to the oblique lower side along the straight line oblique to the horizontal plane, the tapping cutter can be retracted. In this way, the oblique tapping trajectory of the tapping cutter is driven by one motor.

[0038] Moreover, the first and second limit members are installed on the cutting head, the first limit member is located in front of the tapping cutter during the tapping movement, the second limit member is located in front of the tapping cutter during the retraction movement, the bottom of the first limit member is opposite to the tapping surface, and when the tapping cutter and the second limit member are located on the tapping surface, the distance between the bottom of the first limit member and the tapping surface is H, H>0. The spring in the vertical moving mechanism can exert a vertical downward elastic force on the cutting head. Therefore, by reasonably setting the movement stroke of the tapping cutter, the second limit member can be supported on the tapping surface when the tapping cutter moves to the end of the tapping stroke, the second limit member is supported on the tapping surface during the retraction movement of the tapping cutter, the second limit member can be separated from the tapping surface when the tapping cutter moves to the end of the retraction stroke, and the first limit member can be supported on the tapping surface. In this way, during the tapping movement and the retraction movement of the tapping cutter, the second limit member is supported on the arc-shaped tapping surface under the action of the vertical downward elastic force exerted by the spring and the gravity of the cutting head, thereby preventing the cutting head from vertically falling downward. When the tapping cutter moves to the end of the retraction stroke, the second limit member can be separated from the tapping surface, and then the cutting head will vertically fall downward until the first limit member is supported on the tapping surface. The falling height can be determined according to the tapping amount. In this way, the vertical movement of the tapping cutter is realized, only one motor is used in the whole rubber tapping machine, the force direction of the tapping cutter in the traditional spiral tapping does not coincide with the movement direction, the control of the combined movement trajectory is difficult and the reliability is poor, the mechanism of the double-motor driven rubber tapping machine is relatively complex, the stability is poor, and the production and maintenance costs are high.

[0039] 2. The height of the elastic force action point of the first vertical spring on the first vertical sliding seat is equal to the height of the elastic force action point of the second vertical spring on the second vertical sliding seat, which can avoid the rotation torque on the vertical moving mechanism due to the unequal height of the elastic force action points, and ensure that the vertical moving mechanism can smoothly drive the cutting head to move vertically downward.

[0040] 3. Because the first vertical slide is located diagonally above and the second vertical slide is located diagonally below, the second vertical spring that applies elastic force to the second vertical slide applies a vertically downward elastic force to the second vertical slide through the sleeve fitted on the second vertical guide rod. Through a simple structure, the height of the point of application of the elastic force of the first vertical spring on the first vertical slide is equal to the height of the point of application of the elastic force of the second vertical spring on the second vertical slide.

[0041] 4. The single-motor linear drive mechanism also includes an intelligent controller, which can connect to a host computer to control the motor's movement. This enables fully automated operation of the rubber tapping machine.

[0042] 5. The second limiting component is equipped with a rubber pushing structure in the retraction direction of the rubber cutting blade, which can remove solidified latex or other debris from the cutting surface.

[0043] 6. The tapping head is also equipped with a chip-blocking structure. The chip-blocking structure can push the chips generated by the tapping knife in the direction of tapping, thus preventing the chips from falling onto the tapping surface and obstructing the flow of latex, and preventing the chips from mixing with the latex and causing latex contamination. It also prevents the chips from creating resistance to the movement of the tapping knife. Attached Figure Description

DETAILED DESCRIPTION

[0054] The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0055] Embodiment One:

[0056] With reference to Figures 1-8 A single-motor-driven tangent tapping machine, comprising a single-motor linear driving mechanism, a tapping head, a first limiting piece 22, a second limiting piece 4, and a vertical moving mechanism, wherein:

[0057] The single-motor linear driving mechanism is used to drive the tapping head to move along a straight line inclined to the horizontal plane; the tapping head is provided with a tapping knife 21, and the tapping knife 21 can tap rubber and form a tapping surface 5 inclined to the horizontal plane on the rubber tree during the movement of the tapping head along the straight line inclined to the horizontal plane (the tapping surface 5 is arc-shaped in this embodiment); the tapping head can complete knife withdrawal when moving along the straight line inclined to the horizontal plane to the oblique lower side; the first limiting piece 22 and the second limiting piece 4 are installed on the cutting head, and the first limiting piece 22 is located in front of the tapping knife 21 during tapping movement, and the second limiting piece 4 is located in front of the tapping knife 21 during knife withdrawal movement; the bottom of the first limiting piece 22 is opposite to the tapping surface 5; the bottom of the second limiting piece 4 is opposite to the tapping surface 5, and when the tapping knife 21 and the second limiting piece 4 are located on the tapping surface 5, the distance between the bottom of the first limiting piece 22 and the tapping surface is H, and H > 0; the vertical moving mechanism comprises a spring, and the spring can exert a vertical downward elastic force on the tapping head.

[0058] Therefore, the oblique cutting trajectory of the tapping knife 21 is driven by a motor; and because the first limiting member 22 and the second limiting member 4 are installed on the cutting head, the first limiting member 22 is located in front of the tapping knife 21 during the tapping movement, the second limiting member 4 is located in front of the tapping knife 21 during the retraction movement, the bottom of the first limiting member 22 is opposite to the tapping surface 5, the bottom of the second limiting member 4 is opposite to the tapping surface 5, and when the bottom of the second limiting member 4 is located on the tapping surface 5, the distance between the bottom of the first limiting member 22 and the tapping surface 5 is H, the spring in the vertical movement mechanism can exert a vertical downward elastic force on the tapping head, so that the tapping knife 21 can be moved to the end of the tapping stroke, and the second limiting member 4 can be supported on the tapping surface 5 by reasonably setting the movement stroke of the tapping knife 21; during the retraction process, the second limiting member 4 can be supported on the tapping surface 5; when the tapping knife 21 moves to the end of the retraction stroke, the second limiting member 4 and the tapping knife 21 can be separated from the tapping surface 5, and the first limiting member 22 can be supported on the tapping surface 5; therefore, during the tapping movement and the retraction movement of the tapping knife 21, the second limiting member 4 is supported on the arc-shaped tapping surface 5 under the action of the vertical downward elastic force exerted by the spring and the gravity of the tapping head, thereby preventing the tapping head from falling vertically downward; during the retraction, the second limiting member 4 is supported on the tapping surface 5, and when the tapping knife 21 moves to the end of the retraction stroke, the second limiting member 4 and the tapping knife 21 can be separated from the tapping surface 5, so that the tapping head will fall vertically downward until the first limiting member 22 is supported on the tapping surface 5, thereby realizing the vertical movement of the tapping knife 21. Only one motor 16 is used in the whole tapping machine, which solves the problems of the traditional spiral tapping, such as the non-coincidence of the force direction of the tapping knife 21, the difficulty in controlling the combined movement trajectory, the poor reliability, the complex mechanism of the double-motor-driven tapping machine, the poor stability, and the high production and maintenance costs. In addition, the tapping machine has fewer moving parts and high-efficiency action execution mechanism, and requires lower energy consumption, which is more suitable for long-term unmanned operation in the wild. Moreover, the tangent cutting belongs to a short-line cutting method, which shortens the cutting length, reduces the damage to the rubber trees and the consumption of tree bark, and prolongs the tapping life of the rubber trees compared with the traditional half-perimeter spiral cutting method.

[0059] As Figure 1As shown, the single-motor linear drive mechanism includes an inclined screw 15, an inclined guide rod 14, an inclined sliding seat, a mounting base 8 (specifically including a first mounting base and a second mounting base), and a motor 16. The inclined screw 15 and the inclined guide rod 14 are arranged parallel to each other along a straight line inclined to the horizontal plane. The upper end of the inclined screw 15 and the inclined guide rod 14 is supported by the first mounting base, and the lower end of the inclined screw 15 and the inclined guide rod 14 is supported by the second mounting base. The inclined sliding seat 17 is threadedly engaged with the inclined screw 15 and slidably engaged with the inclined guide rod 14. The cutting head is mounted on the inclined sliding seat 17. The power output end of the motor 16 is connected to one end of the inclined screw 15 supported by the first or second mounting base.

[0060] like Figure 1 As shown, the springs in the above-mentioned vertical moving mechanism include a first vertical spring 19 and a second vertical spring 3. The vertical moving mechanism also includes a first vertical guide rod 13, a second vertical guide rod 10, a first vertical slide 18, a second vertical slide 9, a first vertical motion connector, and a second vertical motion connector. The first vertical slide 18 is slidably engaged with the first vertical guide rod 13; the second vertical slide 9 is slidably engaged with the second vertical guide rod 10; the first vertical slide 18 is fixedly connected to the first mounting base via the first vertical motion connector; the second vertical slide 9 is fixedly connected to the second mounting base via the second vertical motion connector; the first vertical spring 19 is sleeved on the first vertical guide rod 13 and can apply a vertically downward elastic force to the first vertical slide 18; the second vertical spring 3 is sleeved on the second vertical guide rod 10 and can apply a vertically downward elastic force to the second vertical slide 9.

[0061] As an improvement, the height of the point of application of the first vertical spring 19 to the first vertical slide 18 is equal to the height of the point of application of the second vertical spring 3 to the second vertical slide 9, and the magnitude of the elastic force is also equal. This avoids the vertical moving mechanism being subjected to rotational torque due to unequal heights of the points of application of the elastic force, ensuring that the vertical moving mechanism can drive the cutting head to move smoothly vertically downward. Specifically, since the first vertical slide 18 is located diagonally above and the second vertical slide 9 is located diagonally below, the second vertical spring 3 can apply a vertically downward elastic force to the second vertical slide 9 through the sleeve 6 fitted onto the second vertical guide rod 10 (the height of the upper end face of the sleeve 6 is the same as the height of the upper end face of the first vertical slide 18). Through this simple structure, the height of the point of application of the first vertical spring 19 to the first vertical slide 18 is equal to the height of the point of application of the second vertical spring 3 to the second vertical slide 9.

[0062] like Figure 1As shown, the rubber tapping machine also includes a rubber tree fixing seat 1 for fixing to the rubber tree. Specifically, it includes a first rubber tree fixing seat and a second rubber tree fixing seat. The upper ends of the first vertical guide rod 13 and the second vertical guide rod 10 are supported on the first rubber tree fixing seat by fixing strips 2 (fixing strips 2 are fixed to the rubber tree fixing seat 1 by bolts 12). The lower ends of the first vertical guide rod 13 and the second vertical guide rod 10 are supported on the second rubber tree fixing seat by fixing strips 2.

[0063] like Figure 1 As shown, a limit sensor 7 (which can be a micro switch, photoelectric sensor, or Hall sensor, etc.) is provided on the mounting base 8. Specifically, a first limit sensor is provided on the first mounting base; a second limit sensor is provided on the second mounting base. When the inclined slide 17 moves obliquely upward along the inclined guide rod 14 to the first set position (end of the rubber tapping stroke), the first limit sensor can send a stop signal to the single-motor linear drive mechanism. When the inclined slide 17 moves obliquely downward along the inclined guide rod 14 to the second set position (end of the retraction stroke), the second limit sensor can send a stop signal to the single-motor linear drive mechanism. Moreover, the single-motor linear drive mechanism also includes an intelligent controller 20. The intelligent controller 20 can be connected to a host computer to control the start, stop, and speed of the motor 16. For example, when the intelligent controller 20 receives a rubber tapping command, it will control the drive motor 16 to drive the inclined screw 15 to rotate, which can realize the fully automatic operation of the rubber tapping machine.

[0064] In addition, the second limiting member 4 is provided with a glue-pushing structure in the retraction direction of the rubber cutting blade 21. This is because latex generally flows down the rubber cutting surface 5 to the guide surface 11, and then down the guide surface 11 to the glue collection bowl. The glue-pushing mechanism can remove solidified latex or other debris from the rubber cutting surface 5.

[0065] Furthermore, the tapping head is equipped with a chip-blocking structure. This chip-blocking structure can push the chips generated by the tapping blade 21 in the tapping direction. Specifically, the chip-blocking structure can be set above the tapping blade 21. This prevents the chips from falling onto the tapping surface 5 and obstructing the flow of latex, and also prevents the chips from mixing with the latex and causing latex contamination. It also prevents the chips from creating resistance to the movement of the tapping blade 21.

[0066] The rubber tapping process of the above-mentioned rubber tapping machine can be carried out according to the following steps:

[0067] (a) such as Figure 2 and Figure 3As shown, the tapping machine is fixed on the rubber tree, and a tapping groove is manually cut at a suitable position of the rubber tree to be tapped, the manually cut tapping surface of the tapping groove is about 30° with the horizontal direction, the manually cut tapping surface of the tapping groove is arc-shaped, the deepest part of the bark cutting is 1.2-1.8 mm away from the xylem of the rubber tree, and the subsequent tapping cutter cuts on the basis of the manually cut tapping surface;

[0068] (II) as shown in Figure 4 The second limiting piece 4 is supported on the manually cut tapping surface;

[0069] (III) as shown in Figure 5 The intelligent controller 20 receives the tapping instruction, drives the motor 16 to rotate the inclined screw rod 15, and then drives the single-motor linear driving mechanism to move downward along the inclined guide rail 14, and the second limiting piece 4 moves along the tapping surface 5 and removes the residual coagulated latex or other sundries on the manually cut tapping surface;

[0070] (IV) as shown in Figure 6 The single-motor linear driving mechanism moves downward until the inclined sliding seat 17 triggers the second limiting sensor installed on the second mounting seat, the motor 16 stops rotating, at this time, the tapping cutter 21 (i.e. the blade marked in the figure) moves to the starting point of the tapping stroke (the ending point of the blade withdrawal stroke), the second limiting piece 4 and the tapping cutter 21 are away from the manually cut tapping surface, and the single-motor linear driving mechanism moves downward along the inclined guide rail 14 under the action of gravity and the elastic force of the spring, and the first limiting piece 22 is supported on the manually cut tapping surface 5;

[0071] (IV) as shown in Figure 7 The intelligent driver drives the motor 16 to rotate the inclined screw rod 15 in the opposite direction, drives the single-motor linear driving mechanism to move upward along the inclined guide rail 14, and drives the tapping cutter 21 to cut the rubber tree bark;

[0072] (V) as shown in Figure 8 The inclined sliding seat 17 triggers the first limiting sensor installed on the first mounting seat, the motor 16 stops rotating, at this time, the tapping cutter 21 moves to the ending point of the tapping stroke (the starting point of the blade withdrawal stroke), a tapping action is completed, the latex flows out of the tapping surface 5, flows into the guide latex surface 11 along the tapping groove, and then flows into the latex collecting bowl along the guide latex surface 11.

[0073] Example two:

[0074] Another single-motor driven tangent type tapping machine is provided in the embodiment, which is different from the first embodiment in that the tapping machine comprises a gas stimulation device for releasing stimulating gas for latex production to the rubber tree.

[0075] As shown in Figure 9As shown, the gas stimulation device comprises a conduit 24, a gas reservoir 25, a control valve 26 and a stimulation gas chamber 27. The gas inlet end of the gas reservoir 25 is connected to the conduit 24 for introducing the stimulating gas (such as ethylene) into the latex stimulating glue, the gas outlet end of the gas reservoir 25 is connected to the conduit 24 for introducing the stimulating gas into the stimulation gas chamber 27, and the gas outlet end of the stimulation gas chamber 27 is inserted into the rubber tree bark. The control valve 26 is arranged on the conduit 24 connecting the gas reservoir 25 and the stimulation gas chamber 27, and the opening and closing of the control valve 26 can be controlled by the intelligent controller 20 or manually.

[0076] To sum up, the above is only the preferred embodiment of the present application, not for limiting the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
