Description

Technical Field

[0001] The present invention relates to the technical field of fruit tree care, and particularly relates to an anti-shooting device and method for young fruit trees. Background Art

[0002] In winter, the temperature is cold. Most young fruit trees start to lose water and dry out gradually from the annual branches of the crown. This phenomenon is called shooting. Shooting can cause the crown to be incomplete, the tree shape to be disordered, the fruiting to be postponed, and in severe cases, the above-ground part will die completely. Reducing the transpiration water loss of branches is the most effective measure to prevent shooting. In the past, the method of lying down and burying soil was mostly used to prevent shooting, and the effect was very good, but it was laborious and time-consuming, and the branches were easily damaged. In recent years, the method of winding plastic film on the branches has been mostly used for winter protection. This method should master two words: "strict" and "tight". The wrapping time is before and after freezing, and it is removed when the apical bud begins to germinate.

[0003] For example, the Chinese patent with the publication number: CN118160556A includes a fixed collar that can be sleeved outside the main trunk or branches of a young fruit tree. A rotating ring is coaxially rotatably fitted on the top surface of the fixed collar. A driving part is arranged on the fixed collar, and the driving part is used to drive the rotating ring to rotate on the fixed collar; a support column for supporting a plastic film winding reel is arranged on the top surface of the rotating ring. In this technical solution, driven by the driving part, the rotating ring will rotate on the fixed collar, and then drive the reel to rotate around the branch or trunk. During the rotation, it is moved along the branch or trunk by hand, and the plastic film will continuously wind around the branch or trunk. The branches or trunks are wound and covered by mechanical means, which can effectively improve work efficiency, reduce operation time, and is conducive to application in large-scale planting.

[0004] When winding the plastic film on the branches, the plastic film is wound on the branches by mechanical means, but the cutting of the plastic film during the winding process still needs to be manual or by other means, and it is difficult to lead the winding of the plastic film to the main trunk part during the winding process. Summary of the Invention

[0005] The purpose of the present invention is to provide an anti-shooting device and method for young fruit trees to solve the above deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for preventing young fruit trees from pulling out branches, comprising a handle and a front frame, the front frame comprising a square block and an arc frame, and a swivel is slidably installed in the arc frame of the front frame, a vertical rod is fixedly installed on the swivel, a swivel rod is rotatably installed on the swivel, a limit plate is installed on the top of the swivel rod, and a cutting knife is fixedly installed on the side wall of the limit plate; a gear is fixedly installed on the bottom end of the swivel rod, and an abutment block is fixedly installed in the square block; a friction wheel that fits the swivel is rotatably installed in the front frame, and a driving motor is arranged at the bottom end of the friction wheel; a plastic film is sleeved on the vertical rod; the friction wheel is driven by the driving motor to rotate, thereby driving the swivel to slide in a circle in the arc frame, and while the swivel slides, the plastic film will be wrapped around the branches, and the swivel rod will passively rotate during the wrapping process, and the plastic film will be automatically cut off after rotating a specified number of times.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0020] Please refer to Figures 1-6, An anti-sprouting device for young fruit trees, comprising a handle 1 and a front frame 2. The front frame 2 includes a square block and an arc-shaped frame. A rotating ring 31 is slidably installed inside the arc-shaped frame of the front frame 2. A vertical rod 32 is fixedly installed on the rotating ring 31. A rotating rod 36 is rotatably installed on the rotating ring 31. A limiting disk 33 is installed at the top end of the rotating rod 36. A cutting knife 35 is fixedly installed on the side wall of the limiting disk 33. A gear 39 is fixedly installed at the bottom end of the rotating rod 36. An abutting block 310 is fixedly installed inside the square block. A friction wheel 51 that fits with the rotating ring 31 is rotatably installed inside the front frame 2. A driving motor is arranged at the bottom end of the friction wheel 51. A plastic film is sleeved on the vertical rod 32. The driving motor is used to drive the friction wheel 51 to rotate, thereby driving the rotating ring 31 to perform circular sliding inside the arc-shaped frame. While the rotating ring 31 slides, it will drive the plastic film to wind around the branch. During the winding process, the rotating rod 36 will be rotated passively, and after rotating a specified number of turns, the plastic film will be automatically cut off. The rolled plastic film together with its winding cylinder is sleeved on the vertical rod 32. Then the limiting disk 33 is sleeved on the rotating rod 36. At this time, the limiting disk 33 will cooperate with the vertical rod 32 to limit the winding cylinder to prevent it from detaching from above. When it is necessary to wind the plastic film around the branch, the branch is placed inside the arc-shaped frame. Then the driving motor is started, which will drive the friction wheel 51 to rotate. When the friction wheel 51 rotates, it will drive the rotating ring 31 to rotate. At this time, the rotating ring 31 will drive the vertical rod 32 and the rotating rod 36 to move. At the same time, before winding, the free end of the plastic film is first attached to the branch, and it can be assisted by hand or tools in the first circle. After winding one or two circles, the assistance can be cancelled. At this time, it can be slowly moved along the branch. At this time, the rotating ring 31 will continue to rotate and drive the plastic film to wind around the branch. At the same time, the abutting block 310 is arranged at a fixed position on the square block. Each time the rotating rod 36 drives the gear 39 to rotate one circle, it will contact the abutting block 310. At this time, the abutting block 310 will push one tooth of the gear 39 to make it rotate a small number of turns. Until after winding several circles, at this time the cutting knife 35 will contact the opened plastic film and cut it. A side block 34 is fixedly installed on the cutting knife 35. The side block 34 is fixedly connected to the limiting disk 33. The cutting knife 35 is connected to the limiting disk 33 through the side block 34.

[0021] In another embodiment of the present invention: a notch is provided at one end of the arc-shaped frame away from the square block and on the rotating ring 31; By providing a notch, it is convenient to directly put the swivel ring 31 and the arc-shaped frame onto the branch through the notch. At the same time, when the plastic film winding is about to end, first remove the arc-shaped frame from the branch through the notch, and then put the front frame 2 and the swivel ring 31 onto the main trunk of the fruit tree from below through the notch. At this time, continue to start the drive motor to drive the swivel ring 31 to rotate. As the swivel ring 31 continues to rotate, the uncut plastic film will continue to wind around the main trunk. And before winding, the plastic film can be appropriately pulled down so that the plastic film drives the branch to open downward. Then the plastic film winds around the main trunk and will keep the branch in an open state, so that the growth of each branch is more outwardly dispersed to increase the inner cavity illumination, and the subsequent sunlight can better irradiate the leaves of the lower branches to give full play to photosynthesis.

[0022] In another embodiment of the present invention: a bottom plate 312 is vertically slidably installed on the swivel ring 31. A connecting rod 315 is fixedly installed on the bottom plate 312. A clamping block 311 is fixedly installed on the connecting rod 315. A clamping groove is opened at the bottom end of the gear 39. A return spring is fixedly installed between the bottom end of the bottom plate 312 and the swivel ring 31. A long strip 314 is fixedly installed on the front frame 2, and an arc-shaped plate 313 is fixedly installed on the bottom plate 312. During the rotation of the swivel ring 31, the return spring will push the bottom plate 312 upward so that the clamping block 311 is stuck in the clamping groove. As the swivel ring 31 rotates, until the arc-shaped plate 313 approaches the long strip 314. At this time, the long strip 314 will contact the arc-shaped plate 313. Then the long strip 314 will abut against the arc-shaped plate 313 to push the arc-shaped plate 313 downward. As the arc-shaped plate 313 descends, it will drive the bottom plate 312 and the clamping block 311 to descend. At this time, the clamping block 311 will move out of the clamping groove. At this time, the clamping block 311 will no longer limit the rotation of the gear 39. When a certain tooth of the gear 39 contacts the abutting block 310, it will be driven to rotate, so that the rotating rod 36 rotates. At this time, as the rotating rod 36 rotates, it will drive the limiting disc 33 and the cutting knife 35 to rotate.

[0023] In another embodiment of the present invention: the clamping block 311 is a multi-prism, and a chamfer is provided at the top end of the clamping block 311. Both the clamping block 311 and the clamping groove are multi-edge settings, so that when the gear 39 rotates a small angle, the clamping block 311 can be inserted into the clamping groove to limit the rotation of the gear 39. When the abutting block 310 drives the gear 39 to rotate, at this time the gear 39 will rotate a small angle. As the gear 39 leaves the abutting block 310, at this time the arc-shaped plate 313 will also leave the long strip 314. At this time, the return spring will push the clamping block 311 upward, and at this time the clamping block 311 will be inserted into the clamping groove through the chamfer to prevent the clamping block 311 and the clamping groove from not being aligned and unable to be inserted at this time.

[0024] In another embodiment of the present invention: a protrusion 361 is fixedly mounted on the rotating rod 36; A blocking block 41 is radially slidably mounted on the vertical rod 32, a side plate 42 is fixedly mounted on the side wall of the blocking block 41, and a first spring 43 is fixedly mounted between the side plate 42 and the inner wall of the vertical rod 32, and a chamfer is provided on the blocking block 41; When the rotating rod 36 rotates, it will drive the protrusion 361 to rotate synchronously. As the cutting knife 35 is about to rotate to approach the elongated plastic film, the protrusion 361 will also approach the chamfer of the blocking block 41. In the subsequent rotation of the rotating rod 36, the protrusion 361 will squeeze the blocking block 41, so that the blocking block 41 extends out from the surface of the vertical rod 32 until the blocking block 41 abuts against the winding drum of the plastic film, so that the blocking block 41 restricts the rotation of the winding drum on the vertical rod 32. At this time, the plastic film can no longer be released from the winding drum, and when the cutting knife 35 approaches, it will cut the plastic film.

[0025] In another embodiment of the present invention: a top plate 37 is rotatably mounted on the top of the rotating rod 36, and a screw 38 is threadedly inserted on the top plate 37; The top plate 37 is rotatably installed on the rotating rod 36. When the limiting plate 33 is sleeved on the rotating rod 36, the top plate 37 is rotated to make it misaligned with the connecting groove of the limiting plate 33. At this time, the screw 38 is screwed into the limiting plate 33 to connect the connecting plate and the rotating rod 36.

[0026] In another embodiment of the present invention: a limit block is fixedly installed on the top of the rotating rod 36, and a "cross" shape is formed between the limit block and the rotating rod 36; A connection groove is provided on the limit plate 33; The connection groove on the limit plate 33 is put on the limit block and the rotating rod 36, and then the limit plate 33 and the rotating rod 36 are connected by screws 38. At this time, the limit plate 33 will not rotate on the rotating rod 36, so that the limit plate 33 can rotate with the rotating rod 36.

[0027] In another embodiment of the present invention: two friction wheels 51 are provided, and the two friction wheels 51 are connected by a belt 52; The servo motor 53 is connected to one of the two friction wheels 51. When the servo motor 53 drives one of the friction wheels 51 to rotate, the other friction wheel 51 will be driven to rotate through the belt 52. The two friction wheels 51 are arranged so that when the rotating ring 31 rotates, if the gap rotates to one of the friction wheels 51, the other friction wheel 51 will continue to drive the rotating ring 31 to rotate, so that the rotating ring 31 rotates continuously.

[0028] A method for preventing young fruit trees from pulling out branches, which is applicable to the above-mentioned device for preventing pulling out branches, comprises the following steps: S1. Slip the winding cylinder of the plastic film onto the vertical rod 32 and connect the limit disc 33 to the rotating rod 36; S2. Then slip the front frame 2 onto the branches of the fruit tree, and then start the servo motor 53. At this time, the servo motor 53 will drive the rotating ring 31 to rotate so as to wind the plastic film around the branches; S3. When the winding is almost finished, slip the front frame 2 onto the main trunk to wind the plastic film around the main trunk and then pull down the branches to open them; S4. As the rotating ring 31 continues to rotate, the cutting knife 35 will cut the plastic film.

[0029] Only some exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
