Description

Technical Field

[0001] The utility model relates to the technical field of rubber tapping equipment, in particular to a rubber tapping blade and a rubber tapping machine. Background Art

[0002] With the advancement of science and technology, automatic rubber tapping machines have gradually replaced the traditional manual labor rubber tapping and have been widely used in rubber tapping production activities. A qualified and efficient rubber tapping machine is inseparable from a sharp, durable and inexpensive rubber tapping blade.

[0003] However, there is at least one of the following problems in the related art: the prior art uses a bending process to manufacture rubber tapping blades, and the tips of the manufactured rubber tapping blades are rounded, which makes it difficult to cut deeply when cutting rubber trees, resulting in incomplete cutting. Utility Model Content

[0004] The technical problem solved by the utility model is that the rubber tapping blades manufactured by the prior art are manufactured by bending process, and the blade tips on the manufactured rubber tapping blades are rounded, and the rounded corners make it difficult to cut deeply when cutting rubber trees, resulting in incomplete cutting.

[0005] In order to solve the above problems, the utility model provides a rubber tapping blade comprising: a main blade and an auxiliary blade that cooperate with each other; the side where the tip of the blade composed of the main blade and the auxiliary blade is located is a first side, and the other side arranged oppositely is a second side; the blade tip comprises a first cutting edge portion arranged on the main blade and a second cutting edge portion arranged on the auxiliary blade; wherein the first cutting edge portion and the second cutting edge portion are arranged at a first angle, the first angle is B, and 40°≤B≤90°.

[0006] Compared with the prior art, the technical effect achieved by adopting this technical solution is: when the angle of B falls within the above-mentioned angle range, B is an acute angle or a right angle, and the tip of the knife is a sharp angle. During the cutting operation, the sharp-angled tip of the knife cuts deeper than the rounded tip of the knife, and the cutting of the cut surface is more accurate.

[0007] In one example of the utility model, the first cutting edge portion is provided with an inner cutting edge surface and an outer cutting edge surface which are arranged opposite to each other; the main cutting blade is provided with a first side surface, the first side surface is connected to the inner cutting edge surface, and is arranged relatively away from the outer cutting edge surface; wherein, the angle formed by the inner cutting edge surface and the first side surface is a first inclination angle, the first inclination angle is C, 0°≤C≤40°; the angle formed by the outer cutting edge surface and the first side surface is a second inclination angle, the second inclination angle is D, 0°≤D≤40°.

[0008] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the rubber tapping blade adopts inner and outer double edges, and the inclination angle falls within the corresponding value range, so that the cutting resistance is minimized when cutting the tree body, the wear of the rubber tapping blade is reduced, and the life of the rubber tapping blade is increased.

[0009] In an embodiment of the present invention, the width of the inner blade surface is G, 0mm≤G≤2mm.

[0010] In an example of the present invention, a connecting line formed at the connection between the primary blade and the secondary blade forms a second angle with the first cutting edge; wherein the second angle is A, 40°≤A≤90°.

[0011] In an example of the present invention, the second blade portion and the connecting line form a third inclination angle K, 10°≤K≤170°.

[0012] Compared with the prior art, the technical effect achieved by adopting this technical solution is that when cutting, the angle formed by the second edge of the auxiliary blade and the contact surface of the rubber tree is too large. When the rubber tapping blade runs to the end point, the auxiliary blade is embedded too deeply in the vertical cutting surface, resulting in a large resistance when the rubber tapping blade is retracted, thereby causing damage to the blade. In this solution, the third inclination angle K is set within the above range, so that the auxiliary blade will not be embedded too deeply in the vertical cutting surface, thereby avoiding the above situation causing damage to the rubber tapping blade.

[0013] In one example of the utility model, the main blade includes a blade portion and a matching portion that cooperate with each other, and the first blade portion is formed on a side of the blade portion away from the matching portion; wherein the thickness of the matching portion is H, 0.5mm≤H≤3mm, the length of the first blade portion is E, 10mm≤E≤50mm; the length of the second blade portion is F, 5mm≤F≤30mm.

[0014] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the thickness of the rubber tapping blade falls within the value range, which not only ensures the strength of the rubber tapping blade, but also ensures the smoothness when cutting rubber trees; the length of the first blade and the second blade falls within the value range, which can be adapted to the provided rubber tapping machine, thereby improving work efficiency; and it is also adapted to the rubber trees being cut as well, so that during the cutting process, rubber strips meeting the required size can be cut, while the impact on the rubber trees can be minimized.

[0015] In an example of the present invention, the main blade and the auxiliary blade are made of alloy material and are connected to each other by welding.

[0016] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: compared with the bending process, the rubber tapping blade provided by the utility model can be manufactured using a harder alloy material, which can greatly improve the durability of the rubber tapping blade and reduce the difficulty of manufacturing.

[0017] The utility model also provides a rubber tapping machine comprising: a circumferential track group, which is used to be installed on a target object; a lifting track, which cooperates with the above-mentioned circumferential track group to achieve a first track movement along the circumferential track group; a transmission mechanism, which is provided with a rubber tapping blade; and the transmission mechanism is movably arranged on the lifting track to achieve a second track movement along the lifting track.

[0018] In one example of the utility model, a mounting mechanism is provided on the transmission mechanism; the mounting mechanism consists of a cutter head and a connecting portion, the cutter head is connected to the connecting portion, and the cutter head is used to install a rubber tapping blade; the connecting portion is used to connect the cutter head and the transmission mechanism.

[0019] In an example of the utility model, a fastener and an adjusting member are provided on the cutter head; the fastener is used to fix the rubber tapping blade on the mounting mechanism, and the adjusting member is used to adjust the position of the rubber tapping blade on the mounting mechanism.

[0020] After adopting the technical solution of the utility model, the following technical effects can be achieved:

[0022] (2) The durability of rubber tapping blades is improved, and the manufacturing difficulty and cost are reduced;

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention will be described in detail below.

[0038] It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and therefore, the scope of protection of the present invention is not limited by the specific embodiments disclosed below.

[0039] Embodiment 1:

[0040] See also Figure 1, the present utility model provides a rubber tapping blade, which includes: a main blade 1 and a secondary blade 2 that cooperate with each other; the tip 3 includes a first cutting edge 110 provided on the main blade 1 and a second cutting edge 210 provided on the secondary blade 2; wherein, the first cutting edge 110 and the second cutting edge 210 are arranged at a first included angle, the first included angle is B, and 40° ≤ B ≤ 90°. In a specific embodiment, when 40° ≤ B < 90°, B is an acute angle, and the tip 3 is a sharp angle; when B = 90°, B is a right angle, and the tip 3 is also a sharp angle. Thus, it can be obtained that 40° ≤ B ≤ 90°, and the tip 3 is a sharp angle. Compared with a rounded corner, when tapping rubber, the cutting surface of the sharp angle is deeper than that of the rounded corner, and the cutting of the cutting surface is more in place.

[0041] Figure 4 As shown in the figure, in an example of the present utility model, the first cutting edge 110 is provided with an inner cutting surface 111 and an outer cutting surface 112 arranged oppositely; the main blade 1 is provided with a first side surface 101, the first side surface 101 is connected to the inner cutting surface 111 and is arranged relatively far away from the outer cutting surface 112; wherein, the included angle formed by the inner cutting surface 111 and the first side surface 101 is a first inclination angle, the first inclination angle is C, and 0° ≤ C ≤ 40°; the included angle formed by the outer cutting surface 112 and the first side surface 101 is a second inclination angle, the second inclination angle is D, and 0° ≤ D ≤ 40°. In this embodiment, in order to more clearly illustrate the first inclination angle C and the second inclination angle D, an auxiliary surface 102 parallel to the first side surface 101 is provided on the main blade 1 and intersects with the first cutting edge 110. For details, see Figure 3 . When C = 0° and 0° < D ≤ 40°, only the outer cutting surface 112 exists on the rubber tapping blade at this time; when 0° < C ≤ 40° and 0° < D ≤ 40°, both the outer cutting surface 112 and the inner cutting surface 111 exist on the rubber tapping blade; when 0° < C ≤ 40° and D = 0°, only the inner cutting surface 111 exists on the rubber tapping blade; the first inclination angle C and the second inclination angle D are not both 0° at the same time.

[0042] As Figure 2 、 Figure 3 shown, in some embodiments, the width of the inner cutting surface 111 is G, and 0 mm ≤ G ≤ 2 mm. The width G of the inner cutting surface 111 is related to the first inclination angle C of the inner cutting surface 111. When the first inclination angle C of the inner cutting surface 111 = 0°, the inner cutting surface 111 does not exist, so the width G of the inner cutting surface 111 = 0 mm; when the first inclination angle 0° < C ≤ 40° of the inner cutting surface 111, the width 0 mm < G ≤ 2 mm of the inner cutting surface 111.

[0043] In the embodiment, the connecting line 4 formed at the connection between the main blade 1 and the auxiliary blade 2 forms a second angle with the first blade portion 110; wherein the second angle is A, 40°≤A≤90°. In some embodiments, the main blade 1 and the auxiliary blade 2 are connected to each other by welding, wherein the welding method includes: common welding methods such as arc welding, submerged arc welding, and gas welding. The rubber tapping blade presents a groove structure at the connection between the main blade 1 and the auxiliary blade 2. The groove structure is an extension of the tip 3 on the rubber tapping blade on the rubber tapping blade. The angle A formed falls within this range, acting on the irregular surface of the rubber tree, and can better cut into the rubber tree. The cut rubber strips and rubber wood chips are smoothly pushed out along the groove structure.

[0044] like Figure 1 As shown, in one example of the present invention, the second blade 210 forms a third inclination angle K with the connecting line 4, 10°≤K≤170°. In this embodiment, the optimal value range of K is 10°≤K≤90°, and the third inclination angle K falls within the above optimal value range, which reduces the depth of the rubber tapping blade embedded in the vertical cutting surface when the rubber tapping blade runs to the end, and avoids damage to the rubber tapping blade due to greater resistance generated by embedding when the tool retreats.

[0045] like Figure 1 and Figure 7 As shown, in one example of the utility model, the main blade 1 includes a blade portion and a matching portion that cooperate with each other, and the first blade portion 110 is formed on the side of the blade portion away from the matching portion; wherein, the thickness of the matching portion is H, 0.5mm≤H≤3mm; the length of the first blade portion 110 is E, 10mm≤E≤50mm; the length of the second blade portion 210 is F, 5mm≤F≤30mm. The thickness of the rubber tapping blade affects the strength of the blade and the smoothness during cutting. When the thickness H of the matching portion is closer to 3mm, the blade of the rubber tapping blade is thicker and the blade strength is high; when the thickness H of the matching portion is closer to 0.5mm, the blade of the rubber tapping blade is thinner, and the resistance is smaller when cutting rubber trees, and the cutting is smoother. The mounting mechanism 9 is provided with a tapping blade accommodating groove, in which the first blade portion 110 is placed. The length of the first blade portion 110 in the accommodating groove is then adjusted by rotating the adjusting screw 13, so that the protruding portion of the tapping blade reaches a suitable position to adapt to the environment of cutting the target rubber tree. During the cutting operation, the length F of the second blade portion 210 falls within this range, which can meet the requirements of the size of the cut rubber strip and the amount of rubber output, while minimizing the impact on the target rubber tree.

[0046] The main blade 1 and the auxiliary blade 2 in this embodiment are made of alloy material and are connected to each other by welding. Compared with the bending process, the rubber tapping blade formed by splicing two independent rubber tapping blades is not affected by stress during rubber tapping, which greatly improves the durability of the rubber tapping blade. Several common grinding methods can be used during the production of the blade, such as concave grinding, convex grinding, chisel grinding, etc., which reduces the manufacturing difficulty compared with the rubber tapping blade in the prior art. The alloy material selected for the rubber tapping blade is a material with high strength and not easy to react with the target object, such as tungsten steel, stainless steel, metal ceramics, etc.

For the convenience of distinction, the rubber tapping blade in the first embodiment is defined as the first rubber tapping blade, and the rubber tapping blade in the second embodiment is defined as the second rubber tapping blade. The parameters of the first rubber tapping blade and the second rubber tapping blade are consistent, and the two are arranged in mirror symmetry, so they will not be described in detail.

In order to better understand the technical solution in this embodiment, two auxiliary lines are provided on the rubber tapping blade of this embodiment, namely the first tangent line and the second tangent line. Among them, the first tangent line extends from the tip 3 and is tangent to the first blade 110; the second tangent line extends from the tip 3 and is tangent to the second blade 210, wherein the first tangent line and the second tangent line form a first angle B.
