Description

A small box branch binding machine Technical Field

[0001] The invention relates to the technical field of agricultural production bundling tools, in particular to a small box branch binding machine. Background Art

[0002] When growing crops such as tomatoes, grapes, and kiwis, we usually need to fix the vines or branches of the plants on bamboo racks or wires to guide their growth or assist in fruiting, thereby increasing crop yield and quality. In order to improve the efficiency of tying branches, compared to the traditional use of ropes for tying branches, operators now usually use tying machines (also called baling machines) to tie and fix the plants.

[0003] For example, CN107517773A discloses a branch binding machine, including a holding member, a holding member force unit, a locking member, and a locking member force unit. The holding member force unit is a torsion spring that applies a force to the holding member in a counterclockwise rotation trend, and the locking member engages with the holding member to keep the holding member in a standby position; the locking member force unit is a compression spring that applies a force to the locking member in a clockwise rotation trend.

[0004] CN211210728U discloses a branch binding machine, which mainly includes a binding strap clamping device, a bow frame, a handle, a frame, a needle box, and a binding strap box. The positioning plate is hinged in the machine box cavity, and a spring is provided on the positioning plate to enable it to have a tendency to rotate in the counterclockwise direction; the pressing needle is hinged in the machine box cavity, and a torsion spring is also provided on the pressing needle to enable it to have a tendency to rotate in the counterclockwise direction; the positioning plate matches the pressing needle.

[0005] However, the branch tying machines in the prior art have the following shortcomings: the size of the machine head is large, and when tying some dense branches, the machine head is likely to break other non-tied branches; or when tying flowering plants (such as cherry tomatoes), the fruit flowers are likely to fall off, thereby causing damage to the plants; and the clamping device in the prior art usually includes a holding member (pressing needle) and a locking member (positioning plate), a holding member force unit and a locking member force unit, and the opening and closing of the holding member are realized based on the mutual transmission relationship between the locking member and the holding member. Due to the complex composition of the above-mentioned structure, there is limited space for optimizing the size of the machine head.

[0006] In view of the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a small box branch binding machine, which only needs to set a torsion spring to realize the opening and closing of the hook head. Compared with the prior art that realizes the opening and closing of the holding mechanism through the transmission of the holding component (pressing needle), the locking component (positioning plate) and the holding component force unit and the locking component force unit, the present invention has a simple structure and ingenious layout, and the protruding size of the machine head is significantly reduced.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] As shown in Figures 1-2, a small box branch binding machine provided in one embodiment of the present invention includes a clamping device 1, a bow frame 2, a handle 3, a frame 4, a needle box 5, and a binding box 6. The frame 4 is linear, and its cross section is "U"-shaped; the bow frame 2 is arc-shaped, and its rear end is hinged to the frame 4. A handle 3 is provided between the bow frame 2 and the frame 4. The handle 3 and the bow frame 2 are hinged to the frame 4 in an "X" shape; the clamping device 1 is provided at the front end of the bow frame 2;

[0041] The handle 3 is composed of a handle frame 31 and a plastic grip 32. The handle frame 31 is embedded in the plastic grip 32. In order to improve the grip friction, a silicone anti-slip pad is provided on the upper surface of the plastic grip 32. The anti-slip pad can be made of silicone.

[0042] The first latch 73 is provided at the rear of the frame 4, and the third latch 73 is provided in the middle of the frame 4. The bottom of the bow frame 2 is hinged to the frame 4 through the first latch 71; a second latch 72 is provided in the middle of the bow frame 2, and the upper end of the handle frame 31 is hinged to the bow frame 2 through the second latch 72. A first hook 311 is provided at the lower end of the handle frame 31, and the first hook 311 is hung on the outside of the third latch 73, and the first hook 311 is sleeved on the outer periphery of the third latch 73; a pull ring is provided between the handle frame 31 and the frame 4, so that the bow frame 2 and the frame 4 have a movement tendency to separate from each other; as shown in Figure 1, when there is no external force, the bow frame 2 remains in the open position relative to the frame 4; as shown in Figure 3, by pressing the handle 3, the bow frame 2 rotates relative to the frame 4, so that the front end of the bow frame 2 contacts the frame 4, and this is the closed position of the bow frame 2.

[0043] As shown in Figures 2-5, the clamping device 1 is installed at the front end of the bow frame 2, and the clamping device 1 includes a machine box 11, a torsion spring 12, a hook head 13, a clamping plate 14 and a forming anvil 15. The machine box 11 is a cavity structure, and the torsion spring 12, the hook head 13, the clamping plate 14 and the forming anvil 15 are all arranged in the cavity of the machine box 11. The hook head 13 is hinged in the cavity of the machine box 11, and the hook head 13 is also connected to a torsion spring 12 that makes it have a clockwise movement tendency. The forming anvil 15 is arranged at the lower end of the machine box 11, and the clamping plate 14 is arranged between the hook head 13 and the forming anvil 15; the hook head 13 includes a pressing block 131, a belt grabbing groove 132, a positioning groove 133 and a top block 134. The belt grabbing groove 132 is opened at the bottom of the hook head 13, the pressing block 131 is arranged on the left side of the hook head, and the top block 134 is arranged on the right side of the hook head 13. A first hinge axis A1 and a second hinge axis A2 are fixedly arranged in the cavity of the machine box 11, the torsion spring 12 is fixedly mounted on the first hinge axis A1, and the hook head 13 is rotatably mounted on the second hinge axis A2. When one end of the torsion spring 12 is inserted into the positioning groove 133, the three points of the positioning groove 133-A1-A2 form a triangular structure. Then, when the end of the torsion spring 12 is inserted into the positioning groove 133, the hook head 13 can be locked.

[0044] The hook head 13 contacts the clamping plate 14 to realize the strap grabbing action. In order to increase the friction force when the hook head 13 grabs the strap, a spherical protrusion is provided on the surface of the clamping plate 14, and a concave and convex pattern is provided on the surface of the strap grabbing groove 132. When the strap grabbing groove 132 at the bottom of the hook head 13 cooperates with the spherical protrusion, the gripping force on the strap can be improved.

[0045] In order to improve the gripping force of the hook head 13 when grabbing the belt, the hook head 13 is also connected to a compression spring 16 which makes it have a tendency to move in a clockwise direction. The upper part of the compression spring 16 is arranged in a compression spring energy storage groove 161. The cross-section of the compression spring energy storage groove 161 is a U-shaped groove fixed in the cavity of the machine box 11; the compression spring energy storage groove 161 is used to fix the contracted compression spring 16 and store the energy of the compression spring 16. When the hook head 13 rotates clockwise, the clamping force of the hook head 13 on the clamping plate 14 is increased under the action of the compression spring 16, which can further improve the gripping force of the strap when the grabbing groove 132 cooperates with the spherical protrusion.

[0046] As shown in Figures 6-9, the front end of the frame 4 is provided with a cutter 421 and a collision block 422, the cutter 421 is fixedly connected to the frame 4, and the collision block 422 is hinged to the frame 4; the collision block 422 cooperates with the pressure block 131 and the top block 134 on the hook head 13; the strap TP is led out from the strap box 6 and passes through the collision block 422. When the bow frame 2 rotates in the closing direction relative to the frame 4, the collision block 422 contacts the pressure block 131 to make the hook head 13 rotate clockwise, thereby making the end of the torsion spring 12 disengage from the positioning groove 133, releasing the locking state of the hook head 13; when the bow frame 2 rotates in the closing direction relative to the frame 4 again, the collision block 422 contacts the top block 134 to make the end of the torsion spring 12 fit into the positioning groove 133, completing the locking of the hook head 13.

[0047] As shown in Figure 10, Figure a is a branch tying machine of the prior art, and Figure b is a branch tying machine of the present invention, W represents the extended width of the machine head, and H represents the height of the machine head; since the clamping device of the prior art usually includes a holding member, a holding member force unit, a locking member, and a locking member force unit, the holding member force unit is a torsion spring, which applies a force with a counterclockwise rotation tendency to the holding member, and the locking member and the holding member are engaged to keep the holding member in the standby position; the locking member force unit is a compression spring which applies a force with a clockwise rotation tendency to the locking member. The above-mentioned structural parts are relatively large, resulting in a larger extended width and height of the machine head, and it can The adjustment space is limited; the present invention is achieved by providing a positioning groove on the top of the hook head. When one end of the torsion spring is stuck in the positioning groove, the torsion spring can reliably lock the hook head; when tying branches, the impact block causes the hook head to rotate clockwise, and the end of the torsion spring slides out of the positioning groove. The torsion spring gives the hook head a clockwise rotation trend. The torsion spring also serves as a force-applying unit of the holding component and a locking component. Compared with the prior art, the holding component and the locking component are simpler in structure and more clever in layout. Comparing Figures a and b, it can be seen that compared with the head size of the prior art, the head extension width W and height H of the present invention are significantly reduced.

[0048] In addition, a needle outlet 51 is provided at the front end of the needle box 5, and a needle pressing head 53 is provided at the bottom of the needle outlet 51. A spring 52 is provided between the lower surface of the needle box 5 and the frame 4. The rear end of the needle box 5 is hinged to the frame 4, and the forming anvil 15 of the clamping device 1 cooperates with the needle outlet 51; when the front end of the needle box 5 is subjected to the downward force of the forming anvil 15, it can be rotated downward relative to the frame 4, and the needle pressing head 53 pushes the staplers in the needle box 5 out, and the staplers bind the straps under the action of the forming anvil 15 (the binding principle is similar to that of a stapler); after the force disappears, under the action of the spring 52, the needle box 5 rotates upward to the initial position relative to the frame 4.

[0049] Working principle:

[0050] The branch binding machine includes standby state, strap grabbing state, branch binding state, and binding and strap cutting state, which are as follows:

[0051] Standby state: As shown in Figures 1-3, Figure 1-2 is the standby state of the branch tying machine before bundling, wherein the bow frame 2 is in the open position relative to the frame 1, and Figure 3 is a structural diagram of the clamping device 1 corresponding to the state of Figure 2. In the standby state, the hook head 13 is in the locked position, its front end remains separated from the clamping strip 14, and the end of the torsion spring 12 is inserted into the positioning groove 133 of the hook head 13.

[0052] Belt grasping state: Combined with Figures 4, 6-7, based on the state shown in Figure 2, force is applied by squeezing the handle 3, and the bow frame 2 rotates downward in a clockwise direction relative to the frame 4; as shown in Figure 6, as the bow frame 2 rotates until the clamping device 1 contacts the front end of the frame 4, at this time, the impact block 412 contacts the pressure block 131, and the impact block 412 gives the hook head 13 a clockwise force, and the end of the torsion spring 12 slides out of the positioning groove 133 of the hook head 13, and the hook head 13 rotates clockwise under the pressure of the torsion spring 12 and the compression spring 16. At this time, the hook head 13 contacts the clamping plate 14, and a spherical protrusion is provided on the surface of the clamping plate 14. The spherical protrusion cooperates with the belt grasping groove 132 to achieve clamping of the strap TP.

[0053] Branch binding state: As shown in Figures 7-8, after the hook head 13 clamps the binding belt TP, the pressing force on the handle 3 is released and the bow frame 2 rotates upward in the counterclockwise direction. As the bow frame 2 rotates, the binding belt TP is stretched; as shown in Figure 8, after the branch binding machine is deeply inserted into the position of the branch to be bound, the binding belt TP is wrapped around the branch to complete the branch binding;

[0054] Binding and cutting state: As shown in Figures 8-9, after the binding is adjusted to a suitable position for the branch, the handle 3 is pressed, and the bow frame 2 moves downward again until the clamping device 1 contacts the front end of the frame 4. The handle 3 is further pressed, and the forming anvil 15 contacts the front end of the needle box 5. Under the pressure of the forming anvil 15, the needle box 5 rotates downward to make the pressing needle head 53 press the stapler out of the needle outlet 51 and contact the forming anvil 15 to complete the binding of the binding TP; at the same time, the impact block 412 contacts the lower arc segment of the hook head 13 and rotates clockwise. Until it contacts the top block 134, as the impact block 412 rotates clockwise, the cutter 411 is exposed, and the cutter 411 cuts the strap TP; then, the impact block 412 continues to press the top block 134 until the end of the torsion spring 12 is stuck in the positioning groove 133 to lock the hook head 13, at this time completing the binding and cutting of the strap; then release the handle 3, the bow frame 2 returns to the open position again, and the hook head 13 returns to the standby state. In this way, one branch binding operation is completed, and the above actions can be repeated to achieve branch binding operations on various branches.
