Description

Technical Field

[0001] This utility model relates to the field of fruit harvesters, specifically a fruit harvester for forestry. Background Technology

[0002] Fruit harvesting is a crucial step in fruit tree cultivation and management, referring to the safe and efficient harvesting of ripe fruit from the tree using manual or mechanical methods. Coconut harvesting is a key step in the coconut industry in tropical regions. Because coconut trees are usually 10-20 meters tall and have smooth, unbranched trunks, the harvesting process is quite difficult and dangerous. Current coconut harvesting methods generally involve manual climbing and long-pole hooking.

[0003] However, harvesters often trample on the trunk and pull on branches and leaves for leverage, which may damage the bark, break branches, and damage the coconut tree's vascular tissue and growth points, affecting its subsequent fruiting ability. If tools such as foot hooks are used while climbing, the trunk may be directly scratched, increasing the risk of pest and disease infection. Using long poles to hook and pull can easily damage branches, flower buds, or immature fruits, affecting the coconut tree's subsequent yield. If not handled properly, it may even cause the main branch to break, damaging the tree structure. Therefore, we propose a fruit harvester for forestry fruit trees. Utility Model Content

[0004] The purpose of this utility model is to provide a fruit harvester for forestry, in order to solve the problems mentioned in the background art, where harvesters often trample on the trunk and pull on the branches and leaves for leverage, which may cause damage to the bark, break branches, and damage the vascular tissue and growth points of the coconut tree, affecting its subsequent fruiting ability; if tools such as foot hooks are used when climbing, the trunk may be directly scratched, increasing the risk of disease and pest infection; when using long poles to hook and pull, branches, flower buds or immature fruits are easily damaged, affecting the subsequent yield of the coconut tree; if the operation is improper, it may even cause the main branch to break, damaging the tree structure.

[0026] Please see Figures 1 to 9 This utility model provides a technical solution: a fruit harvester for forestry fruit trees, including: scissors 1, telescopic rod 2, trolley body 4 and base 43, the trolley body 4 is set above the base 43, the telescopic rod 2 is set above the trolley body 4, and the scissors 1 is fixed above the telescopic rod 2.

[0027] A cart frame 41 is fixed on one side of the cart body 4. A rotating plate 421 is installed inside the cart body 4. A cart cabinet door 42 is installed on the side of the rotating plate 421 away from the cart body 4. A base 43 is connected to the bottom of the cart body 4. Track wheels 44 are located at the four corners of the base 43. The track wheels 44 on the same side of the base 43 are connected to each other through a track body 45. The connection through the track body 45 enhances the mobility and stability of the device in complex terrain and facilitates rapid transfer of the work area.

[0028] A disc seat 32 is provided on the top of the trolley body 4. A rotating seat 3 is fixed on the top of the disc seat 32. A fixed column 31 is connected inside the rotating seat 3. A telescopic rod 2 is provided on the top of the fixed column 31. A fixed block 14 is fixed on one side of the telescopic rod 2. A rotating shaft 213 is provided on the side of the fixed block 14 away from the telescopic rod 2. The rotating shaft 213 passes through the two sides of the fixed block 14 and is connected to the turntable 21. A drive column 211 is provided on the surface of the turntable 21. Limiting slots 24 are opened on the inner surface of the other three side walls of the telescopic rod 2. Limiting sliders 25 are fixed in the area on the surface of the telescopic rod 2 corresponding to the position of the limiting slots 2.

[0029] A second turntable 22 is fixed below the first turntable 21. A second rotating shaft 221 is connected to the side of the second turntable 22 near the telescopic rod 2. A screw 222 is installed on one side of the second rotating shaft 221 that passes through the telescopic rod 2. A first limiting groove 231 is opened on one side of the telescopic rod 2. A fixed slider 23 is provided on the surface of the first limiting groove 231. A screw rod 232 is threadedly connected to the inside of the fixed slider 23. The bottom of the screw rod 232 is evenly grooved on the side surface near the second rotating shaft 221 and engages with the screw rod 222. Through the linkage structure of the screw rod 232, the screw rod 222 and the second rotating shaft 221, the height of the telescopic rod 2 can be quickly adjusted to meet the harvesting needs of different fruit trees and save time and costs.

[0030] The telescopic rod 2 has racks 26 on both sides inside. The surface of the telescopic rod 2 opposite to the racks 26 has holes for connecting gears 27 and meshing with the racks 26. The cooperation between the gears 27 and the racks 26 enables precise adjustment of the height of the telescopic rod 2, adapting to the harvesting needs of fruit trees of different heights.

[0031] When harvesting fruit, first move the trolley body 4 to the fruit tree to be harvested, rotate the disc base 32 to adjust it to a suitable angle, then lift the telescopic rod 2. At the same time, rotate the turntable 22 to drive the rotating shaft 221 to rotate the screw 222. At this time, the lead screw 232 rotates, causing the fixed slider 23 to slide, pushing the remaining telescopic rods 2 to move within the limiting slot 231. Simultaneously, the gear 27 on the telescopic rod 2 rotates, causing the remaining telescopic rods 2 to move away from the trolley body 4. When the telescopic rod 2 is adjusted to a suitable position, align it with the fruit to be harvested. In fact, rotating the drive column 211 clockwise causes the turntable 21 and the shaft 221 to rotate, while pulling the stop block 15 to move. At the same time, the spring 16 is in a compressed state. At this time, the slide drive block 12 drives the scissors 1 to cut the fruit stem. After the cutting is completed, the drive column 211 stops rotating. At this time, the spring 16 provides a rebound force to push the stop block 15 and drive the slide drive block 12 to move away from the trolley body 4. The fruit falls into the hose 6 through the collection cover 53. At this time, the buffer block 51 provides a buffer force for the falling fruit, slowing down the speed of falling into the collection box 5.
