[0041] Please refer to Figure 1 and Figure 2 The present invention provides a high-performance branch tying machine (hereinafter referred to as the branch tying machine), which includes a frame body 100, a clamping arm 200, an operating handle assembly 300, an upper head 400 and a lower head 500. The frame body 100 is used to assemble the clamping arm 200 and the operating handle assembly 300 of the branch tying machine, and the operating handle assembly 300 is arranged to be able to control the clamping arm 200 to move towards or away from the frame body 100, and the movement of the clamping arm 200 relative to the frame body 100 forms a regular movement track 600. It can be understood that the structural members provided on the clamping arm 200 also move along this movement track 600 when the clamping arm 200 moves.

[0042] It should be explained that the frame body 100 is also used to assemble the binding tape box 800 and the nail box 900 of the branch tying machine.

[0043] Specifically, one end of the clamping arm 200 is rotatably connected to the frame body 100, and the other end of the clamping arm 200 and the frame body 100 form a first opening (not marked in the drawings) for accommodating branches. The operating handle assembly 300 is simultaneously rotatably connected to the frame body 100 and the clamping arm 200, and the operating handle assembly 300 is rotatably connected to the frame body 100 through a structural member with elastic potential energy, and the structural member with elastic potential energy includes springs, elastic sheets, etc.

[0044] Please continue to refer to Figure 1, It can be understood that by pressing the operating handle assembly 300 and the frame body 100, the ends of the clamping arms 300 away from the frame body 100 can move towards or away from the frame body 100.

[0045] Preferably, the upper head 400 is arranged at the end of the clamping arm 200 away from the frame body 100, and the lower head 500 is fixedly arranged on the frame body 100 corresponding to the movement track 600 of the upper head 400. When the clamping arm 200 moves towards the frame body 100, the lower head 500 can abut against the upper head 400. Both the upper head 400 and the lower head 500 can be fixed by bolts or installed in a detachable manner such as snap connection or buckle connection.

[0046] Please refer to Figure 4 、 Figure 6 and Figure 7 , Preferably, the upper head 400 includes a housing 410, a first pressing rod 420, a second pressing rod 430, a clamping rod 440 and a pressing belt plate 450. The housing 410 can be divided into two parts, and the two parts can encapsulate the first pressing rod 420, the second pressing rod 430, the clamping rod 440 and the pressing belt plate 450 in the housing 410 by detachable means such as bolts. One ends of both the first pressing rod 420 and the second pressing rod 430 extend out of the housing 410. When the first pressing rod 420 or the second pressing rod 430 abuts against the lower head 500, the clamping rod 440 can rotate, and the pressing belt plate 450 is fixedly arranged in the housing 410 corresponding to the clamping rod 440.

[0047] Specifically, the first pressing rod 420 is slidably arranged in the housing 410, and one end abuts against the housing 410 through a boosting spring 460, and the other end extends out of the housing 410. The boosting spring 460 has the function of resetting the first pressing rod 420. It can be understood that a sliding groove matching the first pressing rod 420 is opened in the housing 410. When pressing the end of the first pressing rod 420 extending out of the housing 410, the first pressing rod 420 can slide in the sliding groove. Removing this pressure, under the action of the boosting spring 460, the first pressing rod 420 can be reset.

[0048] The second pressing rod 430 is rotatably arranged in the housing 410, and one end abuts against a compression torsion spring 470, and the other end extends out of the housing 410. It can be understood that a corresponding rotating shaft is arranged in the housing 410 to rotatably arrange the second pressing rod 430 in the housing 410. When applying pressure to the end of the second pressing rod 430 extending out of the housing 410, the second pressing rod 430 can rotate with a small displacement. Removing this pressure, the second pressing rod 430 can be reset under the action of the compression torsion spring 470.

[0049] The clamping rod 440 is rotatably arranged inside the housing 410, and one end is simultaneously clamped and connected to the first pressing rod 420 and the second pressing rod 430. The other end is arranged opposite to the pressing belt plate 450 and abuts against the pressing belt plate 450. It can be understood that in the state where there is no pressure on the first pressing rod 420 and the second pressing rod 430, the clamping rod 440 abuts against the pressing belt plate 450. When the first pressing rod 420 or the second pressing rod 430 moves inside the housing 410 under pressure, the clamping rod 440 can leave the pressing belt plate 450, thereby forming an opening for accommodating the binding belt. At this time, after removing the pressing force of the first pressing rod 420 or the second pressing rod 430, the clamping rod 440 will press the binding belt tightly on the pressing belt plate 450.

[0050] Please refer to Figure 1 、 Figure 3 and Figure 5 , the lower head 500 includes a tape cutting and pressing nail assembly 510 and a stabilizing frame 520. The tape cutting and pressing nail assembly 510 and the stabilizing frame 520 are both arranged on the frame body 100. When the clamping arm 200 moves towards the frame body 100, the stabilizing frame 520 can abut against the first pressing rod 420 and the second pressing rod 430 on the upper head 400. At the same time, the tape cutting and pressing nail assembly 510 can perform cutting and nailing actions on the binding belt pressed by the clamping rod 440 on the pressing belt plate 450.

[0051] Specifically, the stabilizing frame 520 includes a first convex shaft 521 and a second convex shaft 522. The first convex shaft 521 is used to abut against the first pressing rod 420 and can provide a driving force for the first pressing rod 420 to slide inside the housing 100. The second convex shaft 522 is used to abut against the second pressing rod 430 and can provide a driving force for the second pressing rod 430 to rotate inside the housing 100. It can be understood that by pressing the operation handle assembly 300, the clamping arm 200 moves towards the frame body 100. At the same time, when the upper head 400 abuts against the lower head 500, the first convex shaft 521 abuts against the first pressing rod 420, the second convex shaft 522 abuts against the second pressing rod 430, and at the same time, the tape cutting and pressing nail assembly 510 can perform cutting and nailing actions on the binding belt.

[0052] Please continue to refer to Figure 3 and Figure 11, a limiting groove 5210 is formed on the first convex shaft 521, and a top block 5220 is arranged on the second convex shaft 522. The top block 5220 is arranged on the second convex shaft 522 through a limiting torsion spring 5221. When the first pressing rod 420 abuts against the first convex shaft 521, the first pressing rod 420 is clamped into the limiting groove 5210. At this time, it can be avoided that the first pressing rod 420 and the first convex shaft 521 slide and displace due to excessive force. When the second pressing rod 430 abuts against the second convex shaft 522, the second pressing rod 430 abuts against the top block 5220. At this time, since the top block 5220 is connected with the limiting spring 5221, the top block 5220 can provide a buffering force for the second pressing rod 430, and it also avoids that when the second pressing rod 430 contacts the second convex shaft 522, the upper machine head 400 and the lower machine head 500 slide and displace due to excessive abutting force, thereby causing incomplete cutting of the binding tape and nail driving misalignment problems.

[0053] It can be understood that the top block 5220 arranged through the limiting torsion spring 5221 can provide a buffering force for the second pressing rod 430, and the limiting groove 5210 on the first convex shaft 521 can ensure that the first pressing rod 420 does not slide and displace relative to the first convex shaft 521. Furthermore, it can ensure that when the upper machine head 400 and the lower machine head 500 contact, they will not slide and displace between the upper machine head 400 and the lower machine head 500 due to excessive force on the pressing operation handle assembly 300, thereby ensuring the stability and accuracy of the working position of the tape cutting and nailing assembly 510, enabling the binding machine to cut and nail the binding tape more precisely, greatly improving the working performance of the binding machine, and effectively improving the working efficiency of workers when using the binding machine for agricultural operations.

[0054] It should be explained that in the technical solution of the present invention, when the nail box 900 is assembled to the frame body 100, it can provide binding tape nails for the binding machine. This process belongs to mature prior art, so no more details will be described below.

[0055] Please refer to Figure Figure 2 、 Figure 5 and Figure 9 , preferably, the clamping arm 200 includes a first fastener 210, a first clamping plate 220, a second clamping plate 230 and a second fastener 260. The first clamping plate 220 and the second clamping plate 230 are arranged oppositely and are fixedly connected through bolts, top columns, etc. The first fastener 210 and the second fastener 260 are arranged between the first clamping plate 220 and the second clamping plate 230.

[0056] Specifically, the first clamping plate 220 and the second clamping plate 230 are symmetrical to each other and are arranged opposite to each other. The first fastener 210 is fixed between the first clamping plate 220 and the second clamping plate 230 by bolts, and the second fastener 260 is arranged at a position where the clamping arm 200 is close to the frame body 100.

[0057] Preferably, the first fastener 210 is arranged at a position where the first clamping plate 220 and the second clamping plate 230 are subjected to relatively large forces, thereby improving the stability of the clamping arm 200, avoiding dislocation of the clamping arm 200 after being stressed, and further preventing dislocation of the tape cutting and nail pressing assembly 510.

[0058] Preferably, one end of the clamping arm 200 away from the upper head 400 is rotatably arranged on the frame body 100 through a rotating shaft 240. A stabilizing sleeve 250 is sleeved outside the rotating shaft 240. One end of the stabilizing sleeve 250 is in sliding contact with the first clamping plate 220, and the other end is in sliding contact with the second clamping plate 230. The second fastener 260 is arranged close to the stabilizing sleeve 250 to enhance the structural strength of this position.

[0059] It can be understood that sliding grooves for slidingly contacting the stabilizing sleeve 250 are provided on both the first clamping plate 220 and the second clamping plate 230. A sliding agent can be added to the sliding grooves to reduce the friction between the stabilizing sleeve 250 and the clamping arm 200. At the same time, the stabilizing sleeve 250 can enhance the stability of the clamping arm 200 and prevent dislocation between the first clamping plate 220 and the second clamping plate 230.

[0060] Please refer to Figure 6 、 Figure 7 and Figure 10 , preferably, the upper head 400 further includes a tape fork plate 480 and a nail-fixing U-shaped plate 490. The tape fork plate 480 is fixedly arranged inside the upper head 400, and the nail-fixing U-shaped plate 490 is fixedly arranged on the upper head 400. At the same time, the pressing belt plate 450 and the tape fork plate 480 form a second opening 700 for tying the belt. The pressing belt plate 450 and the tape fork plate 480 can be integrally formed or separately arranged inside the upper head 400.

[0061] Please refer to Figure 5 , preferably, the tape cutting and nail pressing assembly 510 includes a nail pressing piece 511, a tape cutting knife 512 and a tape protecting plate 513. The nail pressing piece 511 is fixedly arranged on the frame body 100, the tape cutting knife 512 is fixedly and vertically arranged on the frame body 100, and the tape protecting plate 513 is arranged on the frame body 100 and is arranged at the tape outlet 810 of the tape tying box 800.

[0062] Specifically, the nail pressing piece 511 is fixed to the main body 100 of the machine frame according to the movement track corresponding to the nail fixing U-shaped plate 490, and is arranged at the nail outlet 910 of the nail box 900. A through groove for accommodating nails is provided on the nail fixing U-shaped plate 490. When the upper machine head 400 abuts against the lower machine head 500, the nail pressing piece 511 can pass through the through groove and can press the nails.

[0063] The tape cutting knife 512 is vertically arranged on the main body 100 of the machine frame according to the movement track corresponding to the tape pressing plate 450. When the upper machine head 400 abuts against the lower machine head 500, the tape cutting knife 512 can perform a cutting action on the binding tape of the binding machine. At the same time, the tape protecting plate 513 is arranged at the tape outlet 810. When the binding tape is pulled out of the tape box 800, the tape protecting plate 513 can fix the binding tape in an upright state, so as to facilitate the pressing action of the tape clamping rod 440 and the tape pressing plate 450 on the binding tape, which is beneficial to ensuring the state of the binding tape, avoiding the sliding of the binding tape, and effectively improving the stability of the tape output of the binding machine.

[0064] Please refer to Figure 5 and Figure 12 Preferably, the lower machine head 500 further includes a binding tape support frame 530. The binding tape support frame 530 is fixedly installed on the main body 100 of the machine frame, and is arranged at the nail outlet 910 of the nail box 900, and is correspondingly arranged for the tape outlet 810 of the tape box 800.

[0065] Please continue to refer to Figure 12 A tape passing port 531 and a through groove 532 are provided on the binding tape support frame 530. The tape passing port 531 is opened corresponding to the tape outlet 810 of the tape box 800. The through groove 532 is opened on the side of the tape passing port 531 close to the operation handle assembly 300. There is a baffle (not marked in the drawing) between the tape passing port 531 and the through groove 532. The tape cutting and nail pressing assembly 510 is fixedly arranged on the main body 100 of the machine frame and is vertically arranged through the through groove 532.

[0066] It can be understood that when the binding tape passes through the tape passing port 531, the binding tape can be in an upright state under the limitation of the tape passing port 531, so as to facilitate the clamping action of the tape clamping rod 440 and the tape pressing plate 450 on the upper machine head 400 on the binding tape. At the same time, when the upper machine head 400 abuts against the lower machine head 500, the binding tape support frame 530 can present the binding tape in a state suitable for cutting, so that the cutting action of the tape cutting knife 512 on the binding tape is more accurate, greatly improving the cutting ability of the binding machine.

[0067] Please refer to Figure 8 On both sides of the main body 100 of the machine frame, flanges are formed into a first protection plate 110 and a second protection plate 120, and a fixing plate 130 for fixedly installing the tape box 800 is arranged at the bottom of one end of the main body 100 of the machine frame far from the lower machine head.

[0068] Specifically, a space for installing the staple box 900 is formed between the first guard plate 110 and the second guard plate 120, and the staple box 900 is fixedly installed in this space. The fixing plate 130 is arranged on one side of the bottom of the frame body 100, which can be the right side or the left side. When the strap box 800 is fixed on the fixing plate 130, a space for grasping (not marked in the attached drawing) is formed between the strap box 800 and the frame body 100. It can be understood that by grasping the space formed by the operating handle assembly 300 and the strap box 800, the clamping arms 200 can move towards the frame body 100, and by releasing the operating handle assembly 300, the clamping arms 200 can move away from the frame body 100.

[0069] While the first guard plate 110 and the second guard plate 120 can provide stable support force for the clamping arms 200, they can also prevent dust from entering the tying machine, effectively improving the dust-proof ability of the tying machine, and thus ensuring the working performance of the tying machine.

[0070] Please refer to Figure 2 and Figure 5 Preferably, the operating handle assembly 300 includes a driving frame 310 and a glove housing 320. The driving frame 310 is rotatably connected to both the frame body 100 and the clamping arms 200, and an elastic member (preferably a spring, but an elastic plate or a torsion spring, etc. can also be selected) is arranged between the frame body 100 and the driving frame 310 for resetting, so that the driving frame 310 is configured to drive the clamping arms 200 to move towards or away from the frame body 100.

[0071] Specifically, a first stabilizing plate 311 and a second stabilizing plate 312 are arranged on both sides where the driving frame 310 abuts against the clamping arms 200. The first stabilizing plate 311 and the second stabilizing plate 312 respectively cover both sides of the clamping arms 200 and cover the connecting part between the clamping arms 200 and the frame body 100. At the same time, the glove housing 320 is sleeved on the outside of the driving frame 310.

[0072] It can be understood that the first stabilizing plate 311 and the second stabilizing plate 312 can prevent the clamping arms 200 from sliding out of place relative to the frame body 100 and can also prevent dust from entering the rotating connection between the clamping arms 200 and the frame body 100, effectively improving the stability of the tying machine, and thus ensuring the cutting accuracy of the strap and the accuracy of nailing.

[0073] It can be understood that in order to improve the user's operating comfort, the glove housing 320 can be made of rubber material or other soft materials with buffering properties such as plastic foam.

[0074] In the technical solution of the present invention, the first pressure rod 420 and the second pressure rod 430 are arranged in the upper machine head 400 to control the pressing belt rod 440. At the same time, a stabilizing frame 520 is correspondingly arranged on the lower machine head 500 opposite to the upper machine head 400. A first convex shaft 521 is arranged on the stabilizing frame 520 for abutting against the first pressure rod 420, and a limiting groove 5210 is formed on the first convex shaft 521 to limit the first pressure rod 420 when it abuts against the first convex shaft 521. It can effectively prevent the first pressure rod 420 from sliding out of position relative to the first convex shaft 521 after the worker exerts excessive force, thereby preventing the cutting position and nailing position of the binding band from being misaligned, which may cause incomplete cutting of the binding band by the cutting knife 512 and incomplete pressing of the nail by the pressing nail piece 511. This greatly improves the working ability of the binding machine for cutting and nailing branches.

[0075] At the same time, a second convex shaft 522 is arranged on the stabilizing frame 520 for abutting against the second pressure rod 430. By arranging a top block 5220 with a buffering function on the second convex shaft 522, and the top block 5220 is installed through a limiting torsion spring 5221. When the worker exerts too much force on the operation handle assembly 300, the top block 5220 on the second convex shaft 522 can perform a buffering action on the second pressure rod 430, thereby avoiding the second pressure rod 430 from sliding out of position relative to the second convex shaft 522. It can effectively ensure the relative working position of the upper machine head 400 and the lower machine head 500, and further ensure that the relative working position of the cutting and nailing component 510 does not shift, effectively improving the accuracy of cutting and nailing of the binding machine.

[0076] A first fastener 210 and a second fastener 260 are arranged on the clamping arm 200 to provide a supporting force for the clamping arm 200, which can ensure that the clamping arm 200 does not slide out of position relative to the frame body 100, and further ensure that the relative working position of the cutting and nailing component 510 does not easily shift, effectively improving the stability of the binding machine.

[0077] A stabilizing sleeve 250 is arranged at the rotational connection between the clamping arm 200 and the frame body 100. By slidingly abutting the two ends of the stabilizing sleeve 250 against the first clamping plate 220 and the second clamping plate 230 of the clamping arm 200 respectively, a stable supporting force can be provided for the clamping arm 200, effectively preventing the clamping arm 200 from sliding out of position relative to the frame body 100, greatly improving the working stability of the binding machine.
