[0034] The present invention will now be described in detail with reference to the accompanying drawings:

[0035] like Figures 1-6 As shown: A bamboo tube feeding mechanism for a bamboo splitting machine, which includes a frame 1. The frame 1 includes a bamboo tube lifting mechanism 2, a bamboo tube vibration transmission mechanism 3, a reciprocating pushing mechanism 4, a bamboo tube diameter measuring mechanism 5, and a bamboo tube pushing mechanism 6 from back to front.

[0036] The bamboo tube lifting mechanism 2 is hinged to the frame 1 and lifts the bamboo tube to the bamboo tube vibration transmission mechanism 3.

[0037] The bamboo tube vibration transmission mechanism 3 is connected to the frame 1, and the bamboo tubes are fed into the bamboo tube diameter measuring mechanism 5 one by one through vibration;

[0038] The reciprocating feeding mechanism 4 works in conjunction with the frame 1 to feed the bamboo tube from back to front into the bamboo tube measuring mechanism 5 through reciprocating motion.

[0039] The bamboo tube diameter measuring mechanism 5 measures the diameter of the bamboo tube and sends it into the bamboo tube pushing mechanism 6;

[0040] The bamboo tube pushing mechanism 6 pushes the bamboo tube forward and returns after pushing the bamboo tube to the equipment of the next process; wherein the bamboo tube diameter measuring mechanism 5 comprises

[0041] The rotating rod 51 is rotatably connected with the rod body on the left side of the rack 1 and has a power device;

[0042] The first base 52 is connected to the rotating rod 51 and rotates with the rotating rod 51;

[0043] The front clamping part 53 is fixed to the first base 52 and has a V-shaped clamping structure with an opening to the right;

[0044] The rear clamping part 54 is slidably connected to the first base 52 and has a V-shaped clamping structure with an opening to the left;

[0045] The distance measuring device 55 is arranged on the front clamping part 53 and the rear clamping part 54 respectively and is used for measuring the distance between the front clamping part 53 and the rear clamping part 54;

[0046] The first driving device 56 is connected to the rear clamping part 54 and is used for driving the rear clamping part 54 to reciprocate forward and backward.

[0047] The power mechanism connected to the rotating rod 51 is generally a motor, and the rotating rod can be rotated forward or backward by driving the motor; since the front clamping part 53, the rear clamping part 54 and the first driving device 56 are arranged on the first base 52, the front clamping part 53, the rear clamping part 54 and the first driving device 56 will rotate with the rotating rod, and the front clamping part 53 and the rear clamping part 54 will also rotate. Considering that the distance measuring device 55 is arranged on the front clamping part 53 and the rear clamping part 54, the diameter of the bamboo tube can be measured when the front clamping part 53 and the rear clamping part 54 are clamped stably. The distance measuring device can be a stroke distance measuring device or an infrared distance measuring device. The device can be directly purchased from the network. In addition, the bamboo tube lifting mechanism 2, the bamboo tube vibration transmission mechanism 3, the reciprocating pushing feeding mechanism 4, the bamboo tube diameter measuring mechanism 5 and the bamboo tube pushing mechanism 6 can be matched with a numerical control mechanism to form a certain cooperation relationship therebetween.

[0048] The front clamping part 53 and the rear clamping part 54 adopt a V shape to ensure that the bamboo can be automatically centered after being clamped.

[0049] The bamboo tube pushing mechanism 6 comprises a pair of left-right symmetrical pushing members, and the pushing member comprises

[0050] The support rail 61 is fixed to the rack 1 and extends forward and backward;

[0051] The pushing rod 62 is provided with a cylinder at the tail portion of the pushing rod 62 for driving the pushing rod 62 to reciprocate forward and backward, and the cylinder is fixed to the rack 1.

[0052] Second base 63, connected to the front end of the push rod 62 and slidingly disposed on the support rail 61;

[0053] Lower clamping part 64, fixed on the second base 63, the overall structure is a V-shaped clamping structure with the opening upward;

[0054] Upper clamping part 65, slidingly connected to the second base 63, the overall structure is a V-shaped clamping structure with the opening downward;

[0055] Second driving device, connected with the upper clamping part 65, for driving the upper clamping part 65 to reciprocate up and down.

[0056] The operation of the bamboo tube diameter measuring mechanism 5 will make the bamboo tube fall in front of the bamboo tube pushing mechanism 6, and then the bamboo tube is clamped by the lower clamping part 64 and the upper clamping part 65, and then pushed forward by the push rod 62.

[0057] Further, the bamboo tube pushing mechanism 6 further comprises a limiting spring 66, which is a metal sheet arranged on the support rail 61 and the front end is upwardly curved; the limiting spring 66 is located in front of the pushing part. Generally, the bamboo tube diameter measuring mechanism 5 places the bamboo tube forward to make it roll naturally, in order to avoid the bamboo tube rolling out of range, so it is necessary to consider setting a spring 66 for limiting.

[0058] The bamboo tube lifting mechanism 2 comprises a front support frame 21, a rear support frame 22 and a lifting cylinder 23, the front support frame 21 and the rear support frame 22 are connected to each other to form a frame structure with V-shaped side surface; the front side of the front support frame 21 is hinged to the rear side of the rack 1; the lifting cylinder 23 is connected to the rack 1 and the front support frame 21 at both ends, thereby driving the frame structure to reciprocate.

[0059] The early bamboo tube can be directly poured into the frame structure formed by the front support frame 21 and the rear support frame 22, and the frame structure is lifted by the lifting cylinder 23, so that all the bamboo tubes roll forward and finally fall on the bamboo tube vibration transmission mechanism 3.

[0060] The bamboo tube vibration transmission mechanism 3 comprises a support platform 31, a vibration support 32 and a support spring 33; the support platform 31 is fixedly arranged at the rear of the rack 1, and the vibrator is fixedly arranged at the bottom of the support platform 31; the vibration support 32 is an L-shaped support hinged to the two sides of the support platform 31; the two ends of the support spring 33 are connected to the L-shaped support and the support platform 31, respectively. The support platform is preferably inclined forward during design, so that the bamboo tube can roll forward after the vibration of the support platform 31.

[0061] The L-shaped bracket is divided into a horizontal rod and a vertical rod, the front end of the horizontal rod is hinged to the middle position on both sides of the support platform 31, and the lower end of the vertical rod is connected to the rear end of the horizontal rod. The L-shaped bracket here can clamp the bamboo tube, and when vibrating, guide the bamboo tube forward.

[0062] A plurality of limiting bars 34 are arranged above the bamboo tube vibration transmission mechanism 3, the limiting bars 34 are inclined downward from front to back, the front end of the limiting bar 34 is fixed on the rack 1, and the gap between the rear end of the limiting bar 34 and the support platform 31 is slightly larger than the diameter of a single bamboo tube, so that the gap can only accommodate one bamboo tube to pass through.

[0063] The reciprocating push feeding mechanism 4 includes a push frame 41, a front connecting rod 42, a rear connecting rod 43, a front double-output shaft motor 44, a rear double-output shaft motor 45, a front swing arm 46, and a rear swing arm 47.

[0064] The front double-output shaft motor 44 and the rear double-output shaft motor 45 are installed in front and back order on the rack 1, and the horizontal height of the front double-output shaft motor 44 is higher than that of the rear double-output shaft motor 45, the output shaft of the front double-output shaft motor 44 is fixedly connected to the proximal end of the front swing arm 46, and the output shaft of the rear double-output shaft motor 45 is fixedly connected to the proximal end of the rear swing arm 47; a first slot 461 is formed in the position close to the distal end of the front swing arm 46, the lower end of the front connecting rod 42 is connected to the first slot 461 through a first locking member, so that the lower end of the front connecting rod 42 can slide in the first slot 461; a second slot 471 is formed in the position close to the distal end of the rear swing arm 47, and the lower end of the rear connecting rod 43 is connected to the second slot 471 through a second locking member, so that the lower end of the rear connecting rod 43 can slide in the second slot 471.

[0065] The upper end of the front connecting rod 42 and the upper end of the rear connecting rod 43 are fixedly connected to the push frame 41, so that the push frame 41 is high in front and low in back; a plurality of bamboo tube limiting grooves 411 are arranged on the push frame 41 from front to back, and the corresponding rack 1 on both sides of the push frame 41 is divided into front, middle, and rear three regions, the upper edge of the front region is a front feeding inclined edge 11 inclined downward from back to front; the upper edge of the middle region is a middle feeding inclined edge 12 inclined downward from front to back, and the middle feeding inclined edge 12 is provided with bamboo tube grooves 13 corresponding in number and distance to the bamboo tube limiting grooves 411; and the upper edge of the rear region is a rear feeding inclined edge 14 inclined downward from back to back.

[0066] As Figures 7-13As shown, the pusher frame 41, the front connecting rod 42, the rear connecting rod 43, the front double-output shaft motor 44, the rear double-output shaft motor 45, the front swing arm 46 and the rear swing arm 47 here essentially drive the pusher frame 41 to move forward, downward, backward, upward and forward again when the front double-output shaft motor 44 and the rear double-output shaft motor 45 rotate. However, considering that the bamboo tube in the bamboo tube limiting groove 411 on the pusher frame 41 will fall into the bamboo tube groove 13 of the rack 1 during the movement of the pusher frame 41, if the pusher frame 41 moves laterally during the process, the bamboo tube will be pressed against the bamboo tube groove 13, causing damage to the bamboo tube, and even causing damage to the front double-output shaft motor 44 and the rear double-output shaft motor 45. Therefore, a first slot 461 is formed at the position close to the distal end of the front swing arm 46, and a second slot 471 is formed at the position close to the distal end of the rear swing arm 47, so as to realize displacement compensation through the first slot 461 and the second slot 471.

[0067] It should be noted that during the upward lifting of the pusher frame 41, the bamboo tube at the front of the support platform 31 will be lifted by the rear of the pusher frame 41 and fall into the rear feeding bevel 14. In addition, when the pusher frame 41 lifts the bamboo tube, the bamboo tube is not directly in the bamboo tube limiting groove 411 of the pusher frame 41, but is located in front of the bamboo tube limiting groove 411 and the upper edge of the pusher frame 41 (see Figure 9 ) during the lifting of the pusher frame 41, the bamboo tube is rolled into the bamboo tube limiting groove 411 (see Figure 10 ) during the lifting of the pusher frame 41, the bamboo tube at the front of the bamboo tube groove 13 of the rack 1 is pushed forward and falls by the pusher frame 41 (see Figure 11 ).

[0068] The working principle (use steps) is as follows:

[0069] 1. The sawed bamboo tubes are pushed into the bamboo tube lifting mechanism of the device, and the lifting is stopped when the bamboo tubes are in the same straight line as the bamboo tube vibration transmission mechanism, and the whole basket loading is completed; 2. The bamboo tubes are vibrated by the bamboo tube vibration transmission mechanism to naturally roll into the reciprocating push feeding mechanism, and the bamboo tubes are fed to the position where the bamboo tube diameter measuring mechanism can hold them; 3. When the bamboo tubes enter the position where the bamboo tube diameter measuring mechanism can hold them, the front clamping part and the rear clamping part clamp the bamboo tubes and realize natural centering, and then the diameter of the bamboo tubes is measured. 4. After the measurement is completed, the bamboo tube diameter measuring mechanism is turned by 120 degrees to make the bamboo tubes naturally fall into the bamboo tube pushing mechanism, the bamboo tube pushing mechanism clamps the bamboo tubes and pushes them to the bamboo breaking machine, when the bamboo breaking machine contacts the bamboo tubes in the radial direction, the bamboo machine releases and moves back. Complete a working cycle.
