Description

Technical Field

[0001] This invention relates to the field of agricultural harvesting technology, and in particular to an agricultural fruit harvester. Background Technology

[0002] Traditionally, fruit harvesting is done manually, a complex and labor-intensive process. In orchards, ripe fruits like dates and ginkgo nuts are traditionally harvested by tapping branches with a pole, causing the ripe fruit to fall from a height, which is then collected into containers – a low-efficiency method. To improve efficiency, a Chinese patent specification discloses a "vibrating harvester" (patent number "200820135334.X"). This handheld harvester uses high-frequency vibration to quickly drop the fruit. Although it doesn't use a pole, it still requires manual contact with the upper part of the tree, and the fixed pole length limits the harvesting height, thus maintaining low efficiency. Another Chinese patent specification discloses a "vibrating fruit tree harvester" (patent number "200820125040.9"). This vibrating fruit tree harvester consists of a fruit tree shaking device, a hydraulic control system, an oil tank, and a counterweight. Its key feature is that the fruit tree shaking device is installed at a considerable distance... The machine, mounted on the front of a 44kW tractor, includes left and right side supports, a main beam, a telescopic boom, a vibratory head suspension frame, and a clamp-type vibratory head. The hydraulic control system is installed on the right side support of the fruit tree vibrating device, within easy reach of the tractor driver. The fuel tank and counterweight are attached to the rear of the tractor at three points. While this machine can be operated by one person, offers good mobility, fast harvesting speed, and its mechanical vibrations do not damage trees, effectively replacing manual labor and saving labor while increasing harvesting efficiency, its complex mechanical structure (including the fruit tree vibrating device, hydraulic control system, fuel tank, and counterweight) results in high manufacturing costs and requires a large working space, making it suitable only for harvesting fruit from trees with ample space around them.

[0003] Existing agricultural fruit pickers typically use a clamp-type vibrating head fixed to the bottom of the fruit tree to vibrate and shake the ripe fruit off the tree. A tarpaulin is then placed over the point where the ripe fruit falls to collect it. However, during the collection process, due to the varying heights of the fruit trees, taller trees are prone to causing fruit to detach from the tarpaulin during vibration, increasing unnecessary fruit collection losses and making the equipment inconvenient for users.

[0014] Beneficial effects:

[0015] 1. In this invention, when harvesting mature fruits from a fruit tree, a positioning vibration mechanism is used to shake the mature fruits off the tree. By activating two sets of drive motors at the top of the mounting frame, the motor drive shafts drive the connecting plate and clamping plate to rotate. The fruit tree is clamped and fixed by the two sets of clamping plates. Elastic sponges are installed on the inner walls of the two sets of clamping plates to prevent damage to the fruit tree during clamping. After the fruit tree is clamped and fixed by the two sets of clamping plates, the vibrator inside the mounting chamber is activated. The vibrator drives the mounting frame and the fruit tree to vibrate, causing the mature fruits at the top of the fruit tree to fall automatically, thus completing the harvesting. This solution greatly improves the efficiency of fruit harvesting compared to traditional manual harvesting.

[0016] 2. When collecting mature fruits from a fruit tree using vibration, this invention uses a positioning and collection mechanism to collect fallen fruits, preventing them from falling onto the work area and becoming difficult to collect, and also preventing damage to the mature fruits. By activating two sets of adjusting motors, the rotating shaft drives the mounting plate and the first adjusting frame to rotate towards the fruit tree. At the same time, the first and second extension arms can be adjusted according to the size of the fruit tree. By activating the first and second drive cylinders respectively, the first and second extension arms can be extended and retracted within the first and second mounting slots. Thus, the collection tarpaulin is unfolded at the bottom of the fruit tree through the first, second, third, fourth, and fifth tarpaulin mounting rods, and the fallen mature fruits are collected through the collection tarpaulin.

[0017] 3. In the process of collecting mature fruit, to prevent the fruit from falling outside the collection tarpaulin during vibration due to the height of the fruit tree, the present invention uses a tarpaulin raising mechanism to raise the tarpaulin. After the collection tarpaulin is adjusted to a suitable position, the first, second, and third drive cylinders inside the first, second, and third fixed frames can be opened respectively. This drives the upper mounting rod, the first mounting rod, and the second mounting rod to move the lifting tarpaulin upward, thereby raising the tarpaulin around the fruit tree and preventing mature fruit from falling outside the collection tarpaulin when the fruit tree vibrates. This increases the fruit collection rate and reduces unnecessary fruit loss.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] The following electrical components are all electrically connected to the external PLC controller.

[0037] The invention provides, for example Figure 1-13An agricultural fruit-picking device is shown, comprising a work area 1, a drive frame 2 mounted on the top of the work area 1, a steering wheel 3 mounted on the top of the drive frame 2, a set of moving wheels 4 mounted on the bottom of the drive frame 2, a moving plate 5 mounted on one end of the drive frame 2, fruit trees 6 planted on the top of the work area 1, a positioning vibration mechanism 7 mounted on one end of the moving plate 5, a positioning collection mechanism 8 mounted on the top of the moving plate 5, a tarpaulin raising mechanism 9 mounted on the top of the positioning collection mechanism 8, a first fixed frame 901 mounted on the top of the positioning collection mechanism 8, a sliding groove 903 formed inside the first fixed frame 901, a first adjusting plate 902 mounted inside the sliding groove 903, a first drive electric cylinder 904 mounted on the bottom end of the first adjusting plate 902, and the bottom of the first adjusting plate 902... A limiting block 905 is installed on one side of the first fixed frame 901, and a first limiting groove 906 is opened on one side of the first fixed frame 901. A collection port 10 is provided at the bottom of the positioning and collecting mechanism 8. When the present invention is used, the moving plate 5 and the mounting frame 701 are moved to one side of the fruit tree body 6 by the drive frame 2 and the moving wheel set 4. By turning on the two sets of adjusting motors 801, the rotating shaft 802 will drive the mounting plate 803 and the first adjusting frame 804 to rotate in the direction of the fruit tree body 6. At the same time, the first extension arm 806 and the second extension arm 811 can be adjusted according to the size of the fruit tree body 6. By turning on the first driving cylinder 807 and the second driving cylinder 812 respectively, the first extension arm 806 and the second extension arm 811 are in the first mounting groove 805 and the second mounting groove 811. The internal telescopic adjustment allows the collecting tarpaulin 821 to be unfolded at the bottom of the fruit tree body 6 via the first tarpaulin mounting rod 813, the second tarpaulin mounting rod 814, the third tarpaulin mounting rod 815, the fourth tarpaulin mounting rod 816, and the fifth tarpaulin mounting rod 817. When the second extension arm 811 extends or retracts, the limiting movable block 820 on one side of the third tarpaulin mounting rod 815 and the fourth tarpaulin mounting rod 816 slides along the interior of the movable groove 818 and the limiting slot 819, thus not affecting the retraction of the second extension arm 811. The collecting tarpaulin 821 collects fallen ripe fruits. After the collecting tarpaulin 821 is adjusted to a suitable position, the first fixing frame 901, the second fixing frame 910, and the third fixing frame 917 can be opened respectively. The first drive electric cylinder 904, the second drive electric cylinder 912, and the third drive electric cylinder 917 inside the 15 cause the first adjusting plate 902, the second adjusting plate 911, and the third adjusting plate 916 to move upward inside the first fixed frame 901, the second fixed frame 910, and the third fixed frame 915, respectively. This, in turn, drives the upper mounting rod 908, the first mounting rod 914, and the second mounting rod 918 to move upward. Through the upper mounting rod 908, the first mounting rod 914, and the second mounting rod 918, the lifting tarpaulin 909 moves upward, thus raising the lifting tarpaulin 909 around the fruit tree body 6. This prevents mature fruit from falling outside the collecting tarpaulin 821 when the fruit tree vibrates, increasing the fruit collection rate and reducing unnecessary fruit loss.After the collection tarpaulin 821 and the lifting tarpaulin 909 are adjusted, the two sets of drive motors 702 at the top of the mounting frame 701 are turned on, causing the motor drive shaft 703 to drive the connecting plate 704 and the clamping plate 705 to rotate. The two sets of clamping plates 705 clamp and fix the fruit tree body 6. Elastic sponges 706 are installed on the inner walls of the two sets of clamping plates 705 to prevent damage to the fruit tree body 6 during clamping. After the fruit tree body 6 is clamped and fixed by the two sets of clamping plates 705, the vibrator 708 inside the mounting chamber 707 is turned on. The vibrator 708 drives the mounting frame 701 and the fruit tree body 6 to vibrate, causing the mature fruits at the top of the fruit tree body 6 to fall automatically, completing the harvesting of the fruit. This solution greatly improves the efficiency of fruit harvesting compared to traditional manual harvesting.

[0038] In this design, when harvesting mature fruits from the fruit tree body 6, a positioning vibration mechanism 7 is used to vibrate and shake the mature fruits off the fruit tree body 6. The positioning vibration mechanism 7 includes a mounting frame 701 installed at one end of a movable plate 5. A drive motor 702 is installed at the top of the mounting frame 701, and a motor drive shaft 703 is installed at the bottom of the drive motor 702. A connecting plate 704 is fixed at the bottom of the motor drive shaft 703, and a clamping plate 705 is installed at one end of the connecting plate 704. An elastic sponge 706 is installed on the inner wall of the clamping plate 705. An installation chamber 707 is opened at the bottom of the mounting frame 701, and a vibrator 708 is installed inside the installation chamber 707. An adjustment box 709 is also installed at one end of the movable plate 5. A drive hydraulic cylinder 710 is installed at the top of the adjustment box 709, and a sliding block 711 is connected to the bottom of the drive hydraulic cylinder 710. A limit slider 712 is installed at one end of the mounting frame 701, and the two ends of the adjustment box 709 are... A limiting slide groove 713 is provided, in which the moving plate 5 and the mounting frame 701 are moved to one side of the fruit tree body 6 via the drive frame 2 and the moving wheel set 4. Then, by opening the two sets of drive motors 702 at the top of the mounting frame 701, the motor drive shaft 703 drives the connecting plate 704 and the clamping plate 705 to rotate. The fruit tree body 6 is clamped and fixed by the two sets of clamping plates 705. Elastic sponge 706 is installed on the inner wall of the two sets of clamping plates 705 to prevent damage to the fruit tree body 6 during the clamping process. After the fruit tree body 6 is clamped and fixed by the two sets of clamping plates 705, the vibrator 708 inside the mounting chamber 707 is opened. The vibrator 708 drives the mounting frame 701 and the fruit tree body 6 to vibrate, so that the mature fruit at the top of the fruit tree body 6 will fall automatically, completing the harvesting of the fruit. This solution greatly improves the efficiency of fruit harvesting compared with traditional manual harvesting.

[0039] This solution, when collecting mature fruits from the fruit tree body 6 using vibration, uses a positioning and collection mechanism 8 to collect fallen fruits, preventing them from falling onto the work area 1 and becoming difficult to collect, and also preventing damage to the mature fruits. The positioning and collection mechanism 8 includes an adjusting motor 801 mounted on the top of the moving plate 5, a rotating shaft 802 mounted on the top of the adjusting motor 801, and a mounting plate 803 connected to the top of the rotating shaft 802. A first adjusting frame 804 is mounted on one end of the mounting plate 803. The first adjusting frame 804 has a first mounting groove 805 inside, a first extension arm 806 is mounted inside the first mounting groove 805, and a first drive cylinder 807 is mounted inside the first mounting groove 805. A limit moving block 808 is installed at one end of the extension arm 806. A first tarpaulin mounting rod 813 is installed at one end of the first adjusting frame 804. A second tarpaulin mounting rod 814 is installed at one end of the first extension arm 806. A second adjusting frame 809 is installed at one end of the limit moving block 808. A second mounting groove 810 is opened inside the second adjusting frame 809. A second extension arm 811 is installed inside the second mounting groove 810. A second driving cylinder 812 is also installed inside the second mounting groove 810. A third tarpaulin mounting rod 815 is installed at one end of the second extension arm 811. A fourth tarpaulin mounting rod 816 is installed at the end of the second extension arm 811 away from the third tarpaulin mounting rod 815. One end of the second adjusting frame 809 is... The system includes a fifth tarpaulin mounting rod 817, a limit block 820 at one end of the third tarpaulin mounting rod 815, a movable groove 818 at one end of the second tarpaulin mounting rod 814 with a limit slot 819 inside, and a tarpaulin collection 821 at one end of the second tarpaulin mounting rod 814. Before vibrating and harvesting the fruit from the fruit tree body 6, two sets of adjusting motors 801 can be activated, causing the rotating shaft 802 to drive the mounting plate 803 and the first adjusting frame 804 to rotate towards the fruit tree body 6. Simultaneously, the first extension arm 806 and the second extension arm 811 can be adjusted according to the size of the fruit tree body 6 by respectively activating the first drive cylinder 807 and the second drive cylinder 808. The cylinder 812 causes the first extension arm 806 and the second extension arm 811 to extend and retract within the first mounting groove 805 and the second mounting groove 810, thereby unfolding the collection tarpaulin 821 at the bottom of the fruit tree body 6 through the first tarpaulin mounting rod 813, the second tarpaulin mounting rod 814, the third tarpaulin mounting rod 815, the fourth tarpaulin mounting rod 816 and the fifth tarpaulin mounting rod 817. When the second extension arm 811 extends and retracts, the limiting movable block 820 on one side of the third tarpaulin mounting rod 815 and the fourth tarpaulin mounting rod 816 will slide along the inside of the movable groove 818 and the limiting slot 819, so as not to affect the retraction of the second extension arm 811, and collect the fallen ripe fruit through the collection tarpaulin 821.

[0040] In this scheme, to prevent the fruit from falling outside the collection tarpaulin 821 during vibration when collecting mature fruit, a tarpaulin raising mechanism 9 is used to raise the tarpaulin during the collection process. The tarpaulin raising mechanism 9 includes a lower mounting rod 907 installed at the bottom of the first fixed frame 901, an upper mounting rod 908 installed at the top of the first adjusting plate 902, a lifting tarpaulin 909 installed between the lower mounting rod 907 and the upper mounting rod 908, a second fixed frame 910 installed at the top of the first extending arm 806, a second adjusting plate 911 installed inside the second fixed frame 910, a second drive cylinder 912 installed inside the second fixed frame 910, a second limiting groove 913 on one side of the second fixed frame 910, a first mounting rod 914 installed at the top of the second adjusting plate 911, a third fixed frame 915 installed at the top of the second extending arm 811, a third adjusting plate 916 installed inside the third fixed frame 915, and a third drive cylinder 909 installed inside the third fixed frame 915. 17. A second mounting rod 918 is installed at the top of the third adjusting plate 916. After the collecting tarpaulin 821 is adjusted to a suitable position, the first driving electric cylinder 904, the second driving electric cylinder 912, and the third driving electric cylinder 917 inside the first fixed frame 901, the second fixed frame 910, and the third fixed frame 915 can be opened respectively. This causes the first adjusting plate 902, the second adjusting plate 911, and the third adjusting plate 916 to move upward inside the first fixed frame 901, the second fixed frame 910, and the third fixed frame 915, respectively. This drives the upper mounting rod 908, the first mounting rod 914, and the second mounting rod 918 to move upward. The upper mounting rod 908, the first mounting rod 914, and the second mounting rod 918 drive the lifting tarpaulin 909 to move upward, thereby raising the lifting tarpaulin 909 around the fruit tree body 6. This prevents mature fruits from falling outside the collecting tarpaulin 821 when the fruit tree vibrates, increasing the fruit collection rate and reducing unnecessary fruit loss.

[0041] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
