When the pressure rod 14 is not subjected to external force, the first elastic member 15 can drive the latch 141 of the pressure rod 14 to be pressed downward toward the telescopic rod 12.

[0033] In some preferred solutions, the feed support mechanism 10 also has the following preferred structure:

[0034] like Figure 3 As shown, a support leg 16 is provided at one end of the telescopic rod 12 away from the sliding sleeve 11 , and the support leg 16 can ensure the stability of the telescopic rod 12 and improve the load-bearing capacity.

[0035] like Figure 3 As shown, the roller 13 is rotatably arranged on the sliding sleeve 11 and the telescopic rod 12, and the roller driving member (such as a motor, the roller driving member is not shown in the present embodiment) is arranged on the outer peripheral side of the sliding sleeve 11, and the output end of the roller driving member is connected to the roller 13 through a chain transmission mechanism, and then the roller 13 can be driven by the roller driving member to automatically rotate to realize autonomous feeding. In some embodiments, multiple rollers 13 are synchronously connected by chains and gears, so that the roller driving member can drive all the rollers 13 to rotate at the same time.

[0036] like Figure 4 As shown, a top column 17 is disposed at the end of the sliding sleeve 11 , and the top column 17 can abut against the pressing rod 14 in the height direction, thereby limiting the downward pressing range of the pressing rod 14 , wherein the first elastic member 15 is coaxially sleeved on the top column 17 .

[0037] like Figure 5 As shown, the frame 20 is arranged on one side of the feeding support mechanism 10, and a material guiding channel 20a for guiding the bamboo material is arranged on the frame 20. The material guiding channel 20a is convenient for guiding the movement of the bamboo, and the material guiding channel 20a is arranged corresponding to the roller 13 along the first horizontal direction.

[0038] like Figure 5 and Figure 6As shown, in this embodiment, the material guide channel 20a is formed as follows: a fixed guide plate 21, a movable guide plate 22, a mounting plate 23, a pull rod 24 and a second elastic member 25 are provided on the frame 20, the fixed guide plate 21 and the movable guide plate 22 are arranged opposite and parallel to each other in the second horizontal direction, and a material guide channel 20a that is conductive along the first direction is formed between the fixed guide plate 21 and the movable guide plate 22; the mounting plate 23 is fixedly arranged on the side of the movable guide plate 22 away from the fixed guide plate 21; the pull rod 24 (columnar) is slidably penetrated on the mounting plate 23 along the second horizontal direction and one end of the pull rod 24 is connected to the movable guide plate 22, in this embodiment, the end of the pull rod 24 is rotatably connected to the back side of the movable guide plate 22, and this embodiment provides a rotatable connection method: a connecting tube 28 is provided on the back side of the movable guide plate 22, and the outer periphery of the connecting tube 28 is connected along its An arc groove 28a is arranged circumferentially, one end of the pull rod 24 is coaxially inserted into the connecting tube 28, and a locking pin (not marked) is arranged on the pull rod 24, and at least a part of the locking pin is inserted into the arc groove 28a, so that the pull rod 24 can be rotated to a certain angle relative to the connecting tube 28, and the pull rod 24 cannot be axially pulled out of the connecting tube 28; a second elastic member 25 (such as a spring) is arranged between the mounting plate 23 and the movable guide plate 22, and the telescopic direction of the second elastic member 25 is configured as a second horizontal direction. The force provided by the movable guide plate 22 toward the fixed guide plate 21 by the second elastic member 25 can clamp the bamboo in the material guide channel 20a and keep it stable during the cutting process. It should be noted that the bamboo in the material guide channel 20a can move in the first horizontal direction when clamped by the movable guide plate 22, that is, the movable guide plate 22 does not completely clamp the bamboo.

[0039] like Figure 5 As shown, in some preferred schemes, the second elastic member 25 is coaxially sleeved on the first guide rod 27, one end of the first guide rod 27 is fixedly connected to the movable guide plate 22, and the first guide rod 27 is slidably penetrated on the mounting plate 23 along the second horizontal direction, and the first guide rod 27 guides the extension and contraction of the second elastic member 25 and plays a guiding and stabilizing role.

[0040] like Figure 5 and Figure 6As shown, in some preferred schemes, a clamping rod mechanism 26 is provided on the mounting plate 23, and a first groove 24a and a second groove 24b are respectively provided on the outer periphery of the pull rod 24, the first groove 24a is arranged along the axial direction of the pull rod 24, and the second groove 24b is arranged along the circumferential direction of the pull rod 24, and the first groove 24a and the second groove 24b are connected, and at least a part of the clamping rod mechanism 26 can be inserted downward into the first groove 24a or the second groove 24b, when the clamping rod mechanism 26 is inserted into the first groove 24a, the pull rod 24 can slide in its axial direction, and when the clamping rod mechanism 26 is inserted into the second groove 24b, the pull rod 24 and the mounting plate 23 cannot have axial (axial direction of the pull rod 24) relative movement, but the clamping rod mechanism 26 and the pull rod 24 can move relative to each other in the circumferential direction.

[0041] like Figure 5 As shown, in this embodiment, through the cooperation of the first groove 24a, the second groove 24b and the clamping rod mechanism 26, when it is not necessary to clamp the bamboo, the pull rod 24 is pulled outward along its axial direction, so that the movable guide plate 22 releases the bamboo; in the process of pulling the pull rod 24, the clamping rod mechanism 26 (specifically the clamping rod 262) and the first groove 24a move relative to each other, and when the clamping rod mechanism 26 enters the range of the second groove 24b, the pull rod 24 is rotated, so that the pull rod 24 and the movable guide plate 22 are restricted, and the second elastic member 25 is compressed at this time. When it is necessary to re-clamp the bamboo, it is only necessary to rotate the pull rod 24 so that the clamping rod mechanism 26 is aligned with the first groove 24a. Under the resetting action of the second elastic member 25, the pull rod 24 and the movable guide plate 22 move toward the fixed guide plate 21 together, and the movable guide plate 22 re-clamps the bamboo.

By designing the third elastic member 263, an elastic force can be given to the clamping rod 262 to float up and down (the clamping rod is always subjected to a downward elastic force when no force is applied), thereby avoiding the jamming phenomenon between the clamping rod 262 and the pull rod 24. At the same time, the staff can manually pull up the clamping rod 262 to release the pull rod 24 to slide freely.

[0043] like Figure 8 and Fig. 9As shown, the cutting assembly 30 includes a vertical plate 31, a rocking plate 32, a first driving member 33, a rotating shaft 34, a transmission member 35, a saw blade 36, a second driving member 37 and a connecting rod mechanism 38; the vertical plate 31 is fixedly arranged on the upper part of the frame 20, and the vertical plate 31 is located on one side of the material guide channel 20a along the second horizontal direction, and the middle position of the rocking plate 32 is hinged to the vertical plate 31, so that the rocking plate 32 can swing up and down in the height direction; the first driving member 33 (such as a motor) and the rotating shaft 34 are respectively arranged at both ends of the rocking plate 32 in the length direction, and the rotating shaft 34 is rotatably arranged on one end of the rocking plate 32 close to the material guide channel 20a, and the output end of the first driving member 33 The first drive member 33 is connected to the rotating shaft 34 through the transmission member 35, and the transmission member 35 can be a belt, a chain, etc. (for example, the transmission member in this embodiment can be a belt and a pulley). The transmission member can realize that the first drive member 33 drives the rotating shaft 34 to rotate; the saw blade 36 is coaxially connected to the rotating shaft 34; along the first horizontal direction, the saw blade 36 is located at the outlet side of the material guide channel 20a, and is used to cut the bamboo; the second drive member 37 (for example, a motor) is arranged on the frame 20, and the second drive member 37 is located below the rocking plate 32, and the output end of the second drive member 37 is connected to the rocking plate 32 through a connecting rod mechanism 38, so that the second drive member 37 can drive the rocking plate 32 to swing up and down.

[0044] like Fig. 9 As shown, in some embodiments, the connecting rod mechanism 38 includes a first connecting rod 381 and a second connecting rod 382, ​​the first ends of the first connecting rod 381 and the second connecting rod 382 are hinged together, the second end of the first connecting rod 381 is hinged to the output end of the second driving member 37, and the second end of the second connecting rod 382 is hinged to the lower end of the rocking plate 32.

[0045] like Fig.10 As shown, the unloading mechanism 40 is arranged on the side of the frame 20 away from the feeding support mechanism 10 along the first horizontal direction. The unloading mechanism 40 includes an unloading platform 41 and a baffle assembly 42. The unloading platform 41 is used to guide the cut bamboo material to a predetermined position, and the baffle assembly 42 is used to limit the movement of the bamboo in the first horizontal direction, play a blocking role on the bamboo, and facilitate segmented cutting of the bamboo.

[0046] like Fig.10 and Fig.11As shown, the unloading platform 41 is sequentially provided with a first unloading slope 411 and a second unloading slope 412 along the first horizontal direction, and the first unloading slope 411 is located between the frame 20 and the second unloading slope 412. Among them, the first unloading slope 411 and the second unloading slope 412 are not arranged in parallel, specifically: the first unloading slope 411 has a first angle θ (positive angle) with the horizontal plane, and the first angle θ can be 40 degrees to 60 degrees, and the second unloading slope 412 has a second angle β (positive angle) with the horizontal plane, and the second angle β can be 50 degrees to 80 degrees. From the perspective of the first horizontal direction, the first unloading slope 411 is inclined to the lower right, and the second unloading slope 412 is inclined to the lower left. In this embodiment, the purpose of providing two cutting slopes is to cut off the waste at the front end of the bamboo and let the waste fall out along the first cutting slope 411 when cutting the bamboo, while other bamboo sections fall out from another direction along the second cutting slope 412.

[0047] In the first horizontal direction, the width D2 of the second cutting slope 412 is 2 to 6 times the width D1 of the first cutting slope 411 .

[0048] In some preferred embodiments, a feeding trough is provided on the feeding platform 41, and the inner bottom surface of the feeding trough is configured as the first feeding slope 411. A plurality of inclined feeding plates are provided on one side of the feeding trough, and the plate surfaces of the plurality of feeding plates are configured as the second feeding slope 412.

[0049] like Fig.10 As shown, a mounting guide bar 43 is fixedly provided at the upper end of the unloading platform 41, and the length direction of the mounting guide bar 43 is configured as a first horizontal direction, wherein the mounting guide bar 43 is provided with a plurality of positioning holes 43a at intervals along the first horizontal direction.

[0050] like Fig.12As shown, the baffle assembly 42 includes a slide 421, a guide block 422 and a baffle 423; the slide 421 is supported on the ground, the guide block 422 is fixedly arranged on the slide 421, and the mounting guide bar 43 is penetrated in the guide block 422, and the slide 421 can only move in the first horizontal direction through the cooperation of the guide block 422 and the mounting guide bar 43; the guide block 422 is provided with a light hole corresponding to the positioning hole 43a, and the positioning bolts can pass through the light holes in sequence and be threadedly connected with the positioning hole 43a, so that the slide 421 and the guide block 422 are fixed together with the mounting guide bar 43; the baffle 423 is arranged on the slide 421, and the baffle 423 and the material guide channel 20a on the frame 20 are arranged in the first horizontal direction. The baffle 423 is used to abut against the end face of the bamboo, so as to limit the length of the bamboo extending to the outside of the frame 20, thereby realizing equal length cutting of the bamboo. Preferably, the installation guide bar 43 is provided with a length scale along the first horizontal direction, and the length scale facilitates the staff to adjust the position of the baffle 423 according to the actual length required for cutting.

[0051] like Fig.12 As shown, in some preferred schemes, the baffle assembly 42 also includes a fourth elastic member 424 (such as a spring) and a travel switch 425; one end of the baffle 423 is hinged to the slide 421, and the two ends of the fourth elastic member 424 are respectively connected to the baffle 423 and the slide 421, and the extension direction of the fourth elastic member 424 is configured as a first horizontal direction; the travel switch 425 is arranged on the slide 421 for monitoring the movement of the baffle 423; the travel switch 425 is communicatively connected to the first drive member 33 and the second drive member 37.

[0052] The upper end of the baffle 423 is hinged to the slide 421 through a hinge or other hinged parts, so that the baffle 423 can swing up and down around the hinge to a certain extent; the two ends of the fourth elastic member 424 are respectively against the back side of the slide 421 and the baffle 423, and the extension direction of the fourth elastic member 424 is configured as the first horizontal direction. A second guide rod 426 is fixedly arranged on the back side of the baffle 423, and one end of the second guide rail is inserted into the waist-shaped hole on the slide 421, and the length direction of the waist-shaped hole is configured as the height direction. The fourth elastic member 424 is coaxially sleeved on the second guide rod 426; when the end of the bamboo is against the baffle 423, the fourth elastic member 424 is compressed. The travel switch 425 is arranged on the slide 421, and the travel switch 425 can be against the back side of the baffle 423. When the end of the bamboo is against the baffle 423, the travel switch 425 is squeezed and generates an opening and closing signal.

[0053] Among them, the travel switch 425 is connected to the first drive member 33 and the second drive member 37 in communication. Specifically, the travel switch 425, the first drive member 33 and the second drive member 37 are all connected to an external driver. This is a prior art and will not be described here. By connecting the travel switch 425 to the first drive member 33 and the second drive member 37 in communication, when the end of the bamboo pushes the travel switch 425 to generate a signal, the signal is fed back to the driver, and the driver drives the first drive member 33 and the second drive member 37 to work synchronously. In this way, the first drive member 33 and the second drive member 37 will work only when the bamboo is cut, and the safety and coordination are better.

[0054] One working mode of the bamboo sawing device of this embodiment is as follows:

[0055] 1. Adjust the extension length of the telescopic rod 12 according to the length of the bamboo. Specifically, by pressing the pressure rod 14 away from one end of the telescopic rod 12, the first elastic member 15 is compressed, and the latch 141 at the front end of the pressure rod 14 is pulled out from the limiting hole 12a of the telescopic rod 12. At this time, the telescopic rod 12 can be pulled out or retracted to a predetermined length along the first horizontal direction, and then the pressure rod 14 is released. The first elastic member 15 drives the latch 141 to move toward the telescopic rod 12. If the latch 141 is not accurately inserted into the limiting hole 12a on the telescopic rod 12 at this time, it is only necessary to slightly pull the telescopic rod 12 so that the limiting hole 12a is aligned with the latch 141 and the telescopic rod 12 can be inserted. The displacement of the telescopic rod 12 is limited by the latch 141 to prevent the telescopic rod 12 from moving during work. Subsequently, the bamboo only needs to be placed on the roller 13, and the bamboo can be fed forward by manual or autonomous rotation of the roller 13;

[0056] Second, adjust the position of the slide 421 and the baffle 423 according to the length of the bamboo segment to be cut, specifically: loosen the positioning bolts on the guide block 422, and adjust the position of the slide 421 together with the baffle 423 and other structures along the first horizontal direction. The length of the bamboo segment cut each time is the distance from the baffle 423 to the saw blade 36. After the adjustment is completed, fix the guide block 422 and the slide 421 and other structures by the positioning bolts;

[0057] 3. Place the bamboo to be cut on the roller 13 and push it into the material guide channel 20a, then rotate the pull rod 24 so that the lower end of the clamping rod 262 rotates into the first groove 24a of the pull rod 24. Under the action of the second elastic member 25, the pull rod 24 moves toward the fixed guide plate 21 along with the movable guide plate 22 and clamps the bamboo (the movable guide plate 22 does not completely clamp the bamboo, and the bamboo can still move in the first horizontal direction), thereby stabilizing the bamboo.

[0058] Fourth, when cutting bamboo, a small part of the front end of each bamboo is unnecessary waste, so it needs to be cut off, but at this time the front end of the bamboo has not yet touched the baffle 423 (if it does not touch the baffle 423, the travel switch 425 on the back side of the baffle 423 will not give the first drive member 33 and the second drive member 37 a working signal), so at this time, the start button can be manually pressed to control the first drive member 33 and the second drive member 37 to work and cut off the waste at the front end of the bamboo. This has an advantage that only by pressing the start button before cutting each bamboo can the cutting work of the entire bamboo be started, which is safer. Of course, those skilled in the art can also directly abandon the practice of the travel switch 425 and directly set the first drive member 33 and the second drive member 37 to work intermittently;

[0059] The cut small piece of waste material falls from one side of the frame 20 onto the first material discharge slope 411, and falls out toward one side along the first material discharge slope 411;

[0060] Then, the bamboo is pushed along the first horizontal direction, so that the front end of the bamboo is against the baffle 423, and the travel switch 425 is pushed to operate, and the first driving member 33 and the second driving member 37 immediately perform a cutting action. Specifically, the first driving member 33 drives the rotating shaft 34 to rotate, and the rotating shaft 34 drives the saw blade 36 to rotate, and then the second driving member 37 drives the rocking plate 32 to swing up and down through the connecting rod mechanism 38. When the rocking plate 32 swings downward, the saw blade 36 cuts the bamboo downward, and the cut bamboo segment falls downward to the second material discharge slope 412, and falls to one side along the second material discharge slope 412. After the current bamboo segment is cut, the remaining bamboo segment is pushed forward again, against the baffle 423 again, and the travel switch 425 is pushed again, and this reciprocating process is repeated.

[0061] When the bamboo is cut to the last section, the movable guide plate 22 and the pull rod 24 are pulled outward to allow the clamping rod 262 to enter the range of the second groove 24b, and then the pull rod 24 is rotated at a certain angle to allow the second groove 24b to cooperate with the clamping rod 262 to limit the position of the pull rod 24 and the movable guide plate 22, thereby facilitating the removal of the last section of bamboo from the material guide channel 20a. When the subsequent bamboo needs to be clamped again, it is only necessary to rotate the pull rod 24.

[0062] The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the protection scope of the present application is not limited to this. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in this application, and these modifications or replacements should be included in the protection scope of this application.
