Description

Technical Field

[0001] This application relates to the field of hazelnut shaping and pruning technology, specifically to a hazelnut shaping and pruning device. Background Technology

[0002] Hazelnuts (scientific name: *Corylus*) are a widely cultivated nut-bearing plant belonging to the genus *Corylus* in the family Betulaceae. Hazelnuts are not only a delicious food but also have high economic and nutritional value. In hazelnut cultivation, pruning equipment is used to shape hazelnut trees into single-trunk or clump-like forms to improve ventilation and light penetration, thereby increasing the yield and quality of the fruit.

[0003] Currently, most shaping and trimming devices require mounting the cutting disc blades on long support rods to raise the trimming height. However, these devices are generally long and the trimming part is heavy, lacking a stable support structure. This results in operators expending a lot of physical effort during use, affecting trimming efficiency. Furthermore, they present the problem of inconvenient placement. Utility Model Content

[0004] Therefore, this application provides a hazelnut shaping and trimming device to solve the problems of existing devices lacking a stable support structure and being inconvenient to place.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A hazelnut shaping and trimming device includes a mounting base, a universal ball joint, and a support rod. A protective cylinder is fixedly installed on the outer side of the upper end of the mounting base, and an electric hydraulic rod is provided in the middle of the upper end of the mounting base. An installation block located above the protective cylinder is connected to the outer side of the upper end of the electric hydraulic rod.

[0007] The upper end of the mounting block is provided with a universal ball, and a mounting bracket is fixedly installed on the upper outer side of the universal ball. A limiting component located on the outer side of the universal ball is installed on the left end of the mounting block.

[0008] The mounting frame has a support rod installed inside, and a fixing bolt is installed through the connection between the mounting frame and the support rod. A disc blade is rotatably installed on the inner side of the upper end of the support rod.

[0009] Furthermore, the electro-hydraulic rod is located inside the protective cylinder, and a reinforcing rod is installed on the upper right side of the protective cylinder via a hanging ring.

[0010] Furthermore, a hook is fixedly installed on the upper right side of the reinforcing rod, and a hanging ring adapted to the hook is fixedly installed on the lower outer side of the support rod.

[0011] Furthermore, the support rod and the fixing bolt are connected by rotation, and a nut is threaded onto the outside of the fixing bolt.

[0012] Furthermore, a drive motor is installed on the upper rear side of the support rod, and the output end of the drive motor is connected to the disc blade.

[0013] Furthermore, the limiting assembly includes an adjusting bolt, a connecting plate, and an anti-slip plate. The adjusting bolt is threadedly installed inside the right side of the mounting block, and the connecting plate is rotatably mounted on the outer right end of the adjusting bolt via a bearing.

[0014] Furthermore, an anti-slip pad is attached to the outer side of the connecting plate near the omnidirectional ball.

[0015] Compared with the prior art, this application has at least the following beneficial effects:

[0016] 1. By placing the middle part of the support rod inside the mounting bracket and inserting the fixing bolt into the mounting bracket and the support rod respectively, the nut is then rotated to install on the outside of the fixing bolt, so that the fixing bolt and the nut are threaded together. This allows the support rod to be stably installed on the inside of the mounting bracket, so that the mounting block, the universal ball and the mounting bracket can provide stable support for the support rod, reducing the physical strength required by the workers during use.

[0017] 2. By lifting the reinforcing rod and inserting the hook into the hanging ring on the outer side of the lower end of the support rod, the reinforcing rod and hook provide initial positioning for the support rod. Then, rotate the adjusting bolt to create a threaded connection between the adjusting bolt and the mounting block. This connection, via the bearing, causes the connecting plate to rotate. The adjusting bolt moves to the right, moving the connecting plate and anti-slip plate synchronously to the right until the anti-slip plate is tightly connected to the universal ball joint. This secures and limits the universal ball joint, preventing it from slipping within the mounting block. The combined effect of the reinforcing rod and hook facilitates the placement of the support rod and disc blade, preventing the drive motor and disc blade on the left side of the support rod from falling due to their weight, thus improving overall stability.

[0024] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 3 As shown, a hazelnut shaping and trimming device according to the first aspect of this application includes: a mounting base 1, a universal ball 5 and a support rod 8. A protective cylinder 2 is fixedly installed on the outer side of the upper end of the mounting base 1, and an electric hydraulic rod 4 is provided in the middle of the upper end of the mounting base 1. An installation block 3 located above the protective cylinder 2 is connected to the outer side of the upper end of the electric hydraulic rod 4. The electric hydraulic rod 4 is located inside the protective cylinder 2.

[0026] The mounting base 1 is equipped with casters on the lower outer side, which makes it easy to move the whole unit to the designated position. The electric hydraulic rod 4 is used to adjust the height of the mounting block 3, so that the height of the disc blade 10 can be adjusted according to the modified height.

[0027] The upper end of the mounting block 3 is provided with a universal ball 5, and the upper outer side of the universal ball 5 is fixedly installed with a mounting bracket 6. The left end of the mounting block 3 is provided with a limiting component located outside the universal ball 5. The limiting component includes an adjusting bolt 11, a connecting plate 12 and an anti-slip plate 13. The adjusting bolt 11 is installed inside the right side of the mounting block 3 by thread, and the connecting plate 12 is rotatably installed on the right outer side of the adjusting bolt 11 by bearing.

[0028] Among them, an anti-slip plate 13 is attached to the outer side of the end of the connecting plate 12 near the universal ball 5. The connecting plate 12 plays the role of installing the anti-slip plate 13, so that the anti-slip plate 13 can be tightly connected to the universal ball 5 under the action of the adjusting bolt 11 and the connecting plate 12, thereby fixing and limiting the universal ball 5 and preventing the universal ball 5 from sliding in the mounting block 3.

[0029] The mounting bracket 6 has a support rod 8 installed inside, and a fixing bolt 7 is installed through the connection between the mounting bracket 6 and the support rod 8. The support rod 8 and the fixing bolt 7 are connected by rotation, and a nut is connected to the outside of the fixing bolt 7 by thread. A disc blade 10 is rotatably installed on the inner side of the upper end of the support rod 8.

[0030] The support rod 8 has a drive motor 9 installed on the upper rear side, and the output end of the drive motor 9 is connected to the disc blade 10. Both the disc blade 10 and the drive motor 9 are installed on the upper end of the support rod 8, so that the drive motor 9 can drive the disc blade 10 to rotate, thereby facilitating the pruning of hazelnut tree branches by the disc blade 10.

[0031] A reinforcing rod 14 is installed on the upper right side of the protective cylinder 2 via a hanging ring. A hook is fixedly installed on the upper right side of the reinforcing rod 14, and a hanging ring that matches the hook is fixedly installed on the lower outer side of the support rod 8.

[0032] The reinforcing rod 14 is rotatably connected to the hanging ring, which facilitates the support rod 8 to be supported and limited by the connection between the hook and the hanging ring. This prevents the drive motor 9 and the disc blade 10 on the left side of the support rod 8 from falling due to their large weight, and improves the overall stability of the placement.

[0033] Working principle

[0034] First, push the protective cylinder 2 to move the entire assembly to the designated position using the casters. Then, place the middle part of the support rod 8 inside the mounting bracket 6, and insert the fixing bolts 7 into the mounting bracket 6 and the support rod 8 respectively. At this point, rotate the nut to install it on the outside of the fixing bolt 7, so that the fixing bolt 7 and the nut are threaded together. This will stably install the support rod 8 on the inside of the mounting bracket 6, allowing the mounting block 3, the ball joint 5, and the mounting bracket 6 to provide stable support for the support rod 8, reducing the physical exertion required by the operator during use.

[0035] Activate the electro-hydraulic lever 4 to extend it, moving the mounting block 3 upwards to the designated height. Then, deactivate the electro-hydraulic lever 4. Hold the lower right side of the support rod 8 and apply force to it. This causes the support rod 8 to rotate through the mounting bracket 6 and the universal ball 5 within the mounting block 3. This changes the angle and orientation of the support rod 8, allowing the disc blade 10 to be adjusted to different positions for pruning hazelnut branches at various locations. After adjustment, activate the drive motor 9 using the button located at the lower right side of the support rod 8. This drives the disc blade 10 to rotate, allowing for the pruning of hazelnut branches.

[0036] After trimming, turn off the disc blade 10 and turn on the electro-hydraulic rod 4, causing it to retract and move the mounting block 3 and support rod 8 downwards to their lowest point. At this point, lift the reinforcing rod 14 and insert the hook into the hanging ring on the outer side of the lower end of the support rod 8. The reinforcing rod 14 and hook then provide initial positioning for the support rod 8. Next, rotate the adjusting bolt 11 to create a threaded connection between the adjusting bolt 11 and the mounting block 3, and rotate it through the bearing and connecting plate 12. The adjusting bolt 11 moves to the right, causing the connecting plate 12 and anti-slip plate 13 to move synchronously to the right until the anti-slip plate 13 is tightly connected to the universal ball 5. This allows the connecting plate 12 and anti-slip plate 13 to fix and limit the universal ball 5, preventing it from sliding within the mounting block 3. Combined with the functions of the reinforcing rod 14 and hook, this facilitates the placement of the support rod 8 and disc blade 10, preventing the drive motor 9 on the left side of the support rod 8 and the disc blade 10 from falling due to their weight, thus improving the overall stability of the placement.

[0037] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
