Description

Technical Field

[0001] This utility model relates to the field of girdling technology for jujube trees, specifically to an electric girdling device for jujube tree branches. Background Technology

[0002] Girdling is an important method for improving the yield and quality of jujube trees. However, traditional girdling techniques have some obvious drawbacks. For example, improper operation during girdling can cause serious damage to the tree, leading to weakened tree vigor, premature leaf drop, and even tree death. Moreover, traditional girdling usually needs to be performed multiple times a year, which not only increases labor intensity but also raises management costs.

[0003] Although existing small-scale electric girdling equipment is compact, portable, and easy to operate, its cutting precision still needs improvement. Some devices struggle to precisely control the cutting depth on the trunk or branches during girdling, affecting the results. Furthermore, the adaptive clamping mechanisms of some devices are ill-suited to jujube tree branches of varying diameters, reducing ease of operation. In addition, improper control of the cutting depth and width during girdling can lead to poor results and may even cause irreversible damage to the tree. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model proposes the following technical solution:

[0005] In a first aspect, this utility model provides an electric ring-barking device for jujube tree branches, comprising: a DC brushless motor, the rotation output shaft of the DC brushless motor being connected to one end of a planetary reducer, the other end of the planetary reducer being connected to a drive bevel gear, and the drive bevel gear being connected to a ring-barking transmission gear disposed around a rotating ring-barking cutter head via a gear set.

[0006] In one possible implementation, the gear set includes a driven bevel gear meshing with the driving bevel gear, the driven bevel gear being fixedly mounted on a first spur gear, the first spur gear meshing with a third spur gear via a second spur gear, the third spur gear being mounted on a fourth spur gear, and the fourth spur gear meshing with the ring-stripping transmission gear.

[0007] In one possible implementation, both the ring-stripping drive gear and the rotary ring-stripping cutter head are provided with a U-shaped feed inlet.

[0008] In one possible implementation, the rotary girdling head is provided with a girdling adjuster, and the girdling adjuster is provided with girdling blades.

[0009] In one possible implementation, the ring-stripping adjuster includes a servo motor connected to a first end of a connecting rod disk, a second end of the connecting rod disk connected to the first end of a connecting rod, and the second end of the connecting rod connected to a sliding rod mounted on a sliding track.

[0010] In one possible implementation, the sliding rod in the girdling adjuster is designed to be quick-released from the girdling blade and the feed roller, and the sliding rod, which is set on the sliding track, is connected to the housing of the connected rotary girdling head by a spring.

[0011] In one possible implementation, the brushless DC motor and planetary reducer are embedded inside the housing of the girdling equipment, and the brushless DC motor is connected to the planetary reducer via a coupling.

[0012] In one possible implementation, the transmission ratio between the driving bevel gear and the driven bevel gear of the gear set is 1:2.

[0013] In one possible implementation, the driven bevel gear of the gear set is fixedly connected to the first spur gear via a keyway, and the transmission ratio between the first spur gear and the second spur gear is 2:1.

[0014] In one possible implementation, a control switch is also included, which is electrically connected to the brushless DC motor.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The electric girdling device of this invention can achieve circumferential peeling of the phloem of jujube branches through a girdling cutter head driven by a motor. Moreover, the clamping mechanism can change with the diameter of the jujube branch, making it easy to operate, greatly reducing the labor intensity of orchard workers and improving work efficiency.

[0017] This utility model designs a revolving ring-barking cutter head, which allows the ring-barking equipment to complete circumferential cutting on its own and to complete the ring-barking operation in a short time. The design incorporates a quick-release slide rail for the ring-barking blades, which allows for quick blade replacement to adapt to the requirements of branches with different diameters and different cutting widths.

Detailed Implementation

[0022] The present solution will now be described in conjunction with the accompanying drawings and specific embodiments.

[0023] Figure 1 A schematic diagram of an electric girdling device for jujube tree branches provided in this application embodiment is shown below. Figure 1 The electric ring-barking device for jujube tree branches in this embodiment includes: a DC brushless motor 1, the rotation output shaft of the DC brushless motor 1 is connected to one end of a planetary reducer 2, the other end of the planetary reducer 2 is connected to a drive bevel gear 17, and the drive bevel gear 17 is connected to a ring-barking transmission gear 10 arranged around the rotating ring-barking cutter head 4 through a gear set.

[0024] Although the DC brushless motor 1 has the advantages of long service life, low maintenance cost, smooth operation and low interference, it needs to be used with a reducer because the motor speed is relatively fast. In this embodiment, the DC brushless motor 1 and the planetary reducer 2 are connected by a coupling, and the DC brushless motor 1 and the planetary reducer 2 are embedded inside the housing 8 of the girdling equipment, which can provide a compact, efficient, precise and reliable drive to ensure the stable operation of the girdling equipment.

[0025] Both the ring-barking transmission gear 10 and the revolving ring-barking cutter head 4 are equipped with U-shaped feeding inlets, and the two are connected by bolts. The U-shaped feeding inlet of the revolving ring-barking cutter head 4 can be directly inserted into the jujube tree branches for ring-barking operations, and the branches that can be inserted have a maximum diameter of 40mm.

[0026] The gear set includes a driven bevel gear meshing with the driving bevel gear. In this embodiment, the transmission ratio between the driving bevel gear and the driven bevel gear of the gear set is 1:2. The gear transmission is smooth, the transmission ratio is precise, the efficiency is high, and the range of power, speed, and size is large, which can better provide transmission power for the girdling operation. To ensure the stability of the electric girdling equipment during the girdling of jujube tree branches, multiple second and third spur gears are set between the back of the rotary girdling cutter head 4 and the first spur gear 18. In this embodiment, the driven bevel gear 3 is fixedly set on the first spur gear 18 through a keyway. Second spur gears 19 are respectively set on both sides of the first spur gear 18. The first spur gear 18 is meshed with the corresponding third spur gear 20 through the two second spur gears 19. The third spur gears 20 are respectively set on the corresponding fourth spur gears 21. Both fourth spur gears 21 are meshed with the girdling transmission gear 10. In this embodiment, the keyway connection can effectively prevent relative slippage between the gears, so that they can be fixed together by the key, and there will be no loosening or falling off during operation.

[0027] See Figure 2 The internal structure diagram of the rotary ring-stripping cutter head provided in this embodiment is shown. In this embodiment, the rotary ring-stripping cutter head 4 is equipped with a ring-stripping adjuster 6. A schematic diagram of the ring-stripping adjuster structure is shown below. Figure 3 As shown, the girdling adjuster 6 is equipped with a servo motor 11, which is connected to the first end of the connecting rod disk 15. The second end of the connecting rod disk 15 is connected to the first end of the connecting rod 13, and the second end of the connecting rod 13 is connected to the sliding rod 14 mounted on the sliding rail 12. The servo motor 11 in the girdling adjuster 6 can control the rotation of the connecting rod disk 15 to control the up and down movement of the connecting rod 13 and the sliding rod 14, thereby achieving the purpose of clamping jujube tree branches of different diameters.

[0028] Furthermore, in this embodiment, the sliding rod 14 of the girdling adjuster 6 adopts a quick-release design with the girdling blade 7 and the feeding roller 5. The sliding rod 14 on both the upper and lower sides is connected to the outer shell of the connected revolving girdling head through the spring 16. The quick-release design of the sliding rod 14 can quickly replace girdling blades of different widths to achieve the purpose of peeling branches of different diameters and different girdling widths.

[0029] When using this jujube branch girdling equipment, firstly, the orchard worker places the jujube branch into the rotary girdling head 4. The servo motor 11 in the girdling adjuster 6 controls the connecting rod disc 15, connecting rod 13, and sliding rod 14 to clamp the jujube branch. At the same time, the feeding roller 5 ensures that the jujube branch will not fall off during the girdling process. Then, the worker presses the control switch 9. After pressing the switch, the DC brushless motor 1 is reduced in speed by the planetary reducer 2. The driving bevel gear connected to the planetary reducer transmits power to the driven bevel gear 3 of the gear set. Through the gear set, the power is transmitted to the girdling transmission gear 10, thereby driving the rotary girdling head 4 to rotate. Finally, the girdling blade 7 will rotate around the branch once, peeling off the phloem of the jujube branch and completing the girdling operation.
