Description

Technical Field

[0001] The invention relates to the field of mechanical equipment, in particular to a high-speed vibrating knife for removing bamboo partitions. Background Art

[0002] The existence of bamboo partitions affects the quality of bamboo splitting, causing the bamboo pieces to bulge or have missing edges at the bamboo partitions after splitting, affecting the production quality of bamboo pieces. It is difficult to remove the bamboo partitions, and there are at least the following difficulties:

[0003] 1. The bamboo tube is conical (along the length direction, the diameter near the brain section is larger than that near the tail section), and the length often exceeds 2 meters, and there are bends and warps. Therefore, if a hard shaft is used, the shape will not match the bent and twisted bamboo tube. If a soft shaft is used, the shaft will bend when the force transmitted is too large, and the transmitted large axial force is not enough to break through the bamboo partition.

[0004] 2. The bamboo partition debris removed in the previous stage accumulates in the bamboo tube, which will have an adverse effect on the bamboo partition cleaning in the later stage.

[0005] 3. The bamboo tube subjected to radial force can be easily broken from the inside. Summary of the invention

[0032] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0033] Please refer to Figures 1 to 5 The present invention provides a high-speed vibration knife for removing bamboo septa, comprising a vibration knife head 2 and a core shaft 1;

[0034] The core shaft 1 comprises a rod body 11 and a piston 12, wherein the piston 12 is mounted at one end of the rod body 11, and an air chamber hole 13 is formed at the axial center of the end of the piston 12 away from the rod body 11, and a first air exchange hole 14 and a second air exchange hole 15 are sequentially formed on one side of the inner wall of the air chamber hole 13 along the axial direction;

[0035] The vibrating cutter head 2 is provided with an air chamber 21 adapted to the piston 12 and a center hole 22 adapted to the rod body 11, the inner wall of the center hole 22 is provided with an exhaust hole 23 connected to the outside, the piston 12 is slidably installed in the air chamber hole 13, and the air chamber hole 13 is divided into a front air chamber 211 and a rear air chamber 212, and the rod body 11 is provided with an air intake channel 16, one end of the air intake channel 16 is connected to the outside, and the other end of the air intake channel 16 is connected to the rear air chamber 212;

[0036] During use, when the first ventilation hole 14 is located in the rear air chamber 212, the high-pressure gas enters the rear air chamber 212 through the air inlet hole of the air chamber 21 of the air inlet channel 16, and enters the front air chamber 211 through the first ventilation hole 14. Because the pressure area of ​​the vibrating cutter head 2 to the left in the front air chamber 211 is greater than the pressure area to the right of the rear air chamber 212, the vibrating cutter head 2 is subjected to a leftward force, causing the vibrating cutter head 2 to move to the left, and the kinetic energy is continuously accelerated and accumulated during the movement. When the current vibrating cutter head 2 moves to the left until the center hole 22 blocks the first ventilation hole 14, the first ventilation hole 14 is closed, and the second ventilation hole 1 5 is connected to the exhaust hole 23. At this time, the high-pressure gas in the rear air chamber 212 can no longer pass through the first air exchange hole 14 to the front air chamber 211. The front air chamber 211 now discharges the gas to the outside through the second air exchange hole 15. The generated high-pressure gas is ejected outward, and the pressure of the front air chamber 211 drops sharply. At this time, the high-pressure gas only exists in the rear air chamber 212, which generates rightward pressure on the vibrating cutter head 2, decelerates the vibrating cutter moving to the left, and drives the vibrating cutter to move to the right, until the first air exchange hole 14 returns to the rear air chamber 212, realizing the high-speed reciprocating acceleration and deceleration motion of the vibrating cutter and ejecting high-speed airflow to the tail.

[0037] Preferably, the head and tail of the vibrating cutter head 2 are both provided with multi-stage scraping teeth 24, so that the vibrating cutter head 2 is in the shape of a stepped cylindrical docking structure. When the cutter is advanced, the multi-stage scraping teeth 24 cooperate with the vibrating cutter head 2 to reciprocate at high speed to break the bamboo partition fragments step by step. When the cutter is retracted, the multi-stage scraping teeth 24 at the tail can continue to remove the bamboo partition fragments, and the cutter is not easy to get stuck when retracting. The multi-stage scraping teeth 24 act vertically on the bamboo partition to prevent radial force from being generated when contacting the bamboo partition to break the bamboo tube.

[0038] In this embodiment, when the piston 12 contacts the side wall of the air chamber 21 away from the central hole 22 , the first air exchange hole 14 and the second air exchange hole 15 are both located in the rear air chamber 212 .

[0039] In this embodiment, there are multiple exhaust holes 23 arranged in a circular array on the inner wall of the center hole 22. The multiple exhaust holes 23 simultaneously eject high-speed airflow, which can move the crushed bamboo partitions backward and eject the bamboo tube without affecting the vibrating cutter head 2 to continue to crush the bamboo partitions forward.

[0040] In this embodiment, the rod body 11 is a flexible shaft. The destructive force of the present application on the bamboo partition mainly relies on the inertia of the vibrating knife. Therefore, the rigidity of the rod body 11 is required to be relatively low. The use of a flexible shaft can cooperate with the vibrating knife to enter the interior of the long bamboo tube, adapt to the curved bamboo tube, and meet the bamboo partition crushing needs of different bamboo tubes.

[0041] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.

[0042] 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.
