Description

Technical Field

[0001] This utility model relates to the technical field of negative pressure fruit picking devices, specifically to a negative pressure picking head for thinning flowers and fruits. Background Technology

[0002] In apple cultivation, flower and fruit thinning is a crucial step in ensuring apple quality and yield. Proper flower and fruit thinning can adjust the tree's load, promote fruit development, improve fruit size and quality, strengthen the tree, and prevent alternate bearing.

[0003] When thinning flowers and fruits, traditional mechanized harvesting equipment is not very flexible and is prone to accidental picking. Currently, the thinning of flowers and fruits is mainly done manually. However, due to the relatively high height of fruit trees and the limited height of people, it is difficult to operate manually. At this time, corresponding auxiliary tools are usually used to carry out the harvesting operation. Common auxiliary tools include air suction negative pressure harvesting heads. These air suction negative pressure harvesting heads, together with corresponding air sources and support rods, can achieve the effect of harvesting from high places.

[0004] For example, the utility model patent with authorization announcement number CN217241507U discloses a suction cup-type apple-picking robot, including a headstock mounting base, a headstock device, an air inlet, a suction cup mounting frame, a distance sensor, and a suction cup device. The headstock mounting base has a mounting hole at its tail. A distance sensor is installed in the middle of the inner cavity of the headstock device. The side wall has a suction cup mounting frame and an air inlet. The suction cup mounting frame can mount the suction cup device, and an air inlet pipe can be installed at the air inlet to provide negative pressure via an external air pump. The suction cup device consists of a metal conduit and silicone suction cups. This utility model, by setting a distance sensor, can identify a suitable gripping position. The four evenly distributed suction cups ensure the stability of fruit gripping, making it easy to pick apples from the tree. By using soft silicone material for the suction cups, the apple skin can be protected from damage during picking.

[0005] While this technology offers advantages such as ensuring fruit clamping stability and facilitating apple removal from the tree, most current pneumatic suction negative pressure harvesting heads still have some shortcomings. For example, to facilitate pipeline layout, components such as the battery and pump are usually installed near the end of the negative pressure harvesting head. This significantly increases the weight near the end, causing hand fatigue and soreness for workers holding it for extended periods. Furthermore, it makes it difficult for workers to maintain balance between the negative pressure harvesting head and their hand, affecting the harvesting effect. Therefore, we propose a flower and fruit thinning pneumatic suction negative pressure harvesting head. Utility Model Content

[0006] The purpose of this invention is to provide a negative pressure air-suction harvesting head for thinning flowers and fruits, so as to solve the defects mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A flower and fruit thinning air-suction negative pressure harvesting head includes a negative pressure suction cup harvesting robot body.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-4 This utility model provides a technical solution: a negative pressure picking head for flower and fruit thinning using air suction, including a negative pressure suction cup picking robot body 1. The negative pressure suction cup picking robot body 1 is a conventional technology and will not be described in detail here. The negative pressure suction cup picking robot body 1 is provided with multiple gripping rods 10. Two adjacent gripping rods 10 are detachably connected. The negative pressure suction cup picking robot body 1 is detachably connected to the gripping rod 10 located at the top. A threaded joint 11 is fixedly installed at the bottom end of the gripping rod 10. A threaded hole 12 is provided in the body of the top end of the gripping rod 10. The threaded joint 11 is threadedly connected to the corresponding threaded hole 12, so that the operator can flexibly adjust the number and overall length of the gripping rods 10 according to the height of the fruit tree and the actual operation requirements, making the picking head suitable for apple flower and fruit thinning operations at different heights, thus improving the versatility and ease of operation of the equipment.

[0033] In this embodiment, a heat dissipation battery box 3 is provided on one side of the grip rod 10, and a rechargeable battery 30 for power supply is provided inside the heat dissipation battery box 3. A shoulder strap 321 is provided on one side of the heat dissipation battery box 3. A negative pressure suction pump 34 is provided on the side of the heat dissipation battery box 3. The negative pressure suction pump 34 is connected to the connector on the negative pressure suction cup picking robot body 1 through a suction tube 35. Specifically, the end of the suction tube 35 is flange-connected to the negative pressure suction cup picking robot body 1, and the other end of the suction tube 35 is threaded-connected to the negative pressure suction pump 34, making loading and unloading more convenient. The rechargeable battery 30 supplies power to the negative pressure suction pump 34, and the shoulder strap 321 is used for carrying on the shoulder.

[0034] Specifically, both the threaded connector 11 and the gripping rod 10 are hollow structures. The suction tube 35 and the corresponding cable pass through the ends of the corresponding gripping rod 10 and the threaded connector 11. This design effectively avoids the problem of pipe entanglement caused by the suction tube 35 being exposed, making the appearance of the equipment more concise and neat. At the same time, it reduces the risk of operators being tethered by the pipes during operation, and improves the smoothness and safety of operation.

[0035] like Figure 1 and Figure 4 As shown, a rubber bracket 2 is detachably installed on the bottom end of the grip rod 10 at the bottom. A switch 23 is provided on the rubber bracket 2. The rechargeable battery 30, the negative pressure suction pump 34 and the switch 23 are electrically connected, so that the operator can easily control the start and stop of the negative pressure suction pump 34 when holding the equipment, without having to frequently search for the switch position, thus optimizing the operation process and improving work efficiency.

[0036] like Figure 4 As shown, the rubber clamp 2 is provided with a clamping chamber 20, and the wall of the clamping chamber 20 is provided with a clamping hole 21. The gripping rod 10 is inserted into the clamping chamber 20 along the clamping hole 21. The cross-section of the clamping chamber 20 is larger than half a circle, so that the gripping rod 10 can be quickly inserted into the clamping chamber 20 for installation and disassembly is also more convenient. This facilitates the quick assembly and disassembly of the rubber clamp 2, making it easier for daily equipment maintenance, repair and component replacement, and reducing the difficulty of equipment maintenance. The rubber clamp 2 is threaded with a fastening screw 22, so that after the rubber clamp 2 is clamped, tightening the fastening screw 22 can achieve a further fixing effect.

[0037] like Figure 3As shown, the top of the heat dissipation battery box 3 is connected to the outside. A dust cover 31 is hinged to the top surface of the heat dissipation battery box 3. The dust cover 31 prevents dust, rainwater and other impurities from entering, protects the internal battery and circuit components, and extends the service life of the equipment. A side plate 33 is fixedly installed on the side of the heat dissipation battery box 3. The negative pressure suction pump 34 is fixedly installed on the side plate 33. The side plate 33 is used to fix the negative pressure suction pump 34, making the equipment structure layout more compact and reasonable.

[0038] like Figure 3 As shown, two symmetrical cable management racks 36 are fixedly installed on the back of the heat dissipation battery box 3. The cross-section of the cable management rack 36 is L-shaped. A back plate 32 is fixedly installed on the front of the heat dissipation battery box 3. Shoulder straps 321 are fixedly installed on the back plate 32. There are two shoulder straps 321. Operators can use the cable management racks 36 with the binding rope to neatly bundle and store excess cable length, avoiding cable tangling. At the same time, the shoulder straps 321 transfer part of the weight of the equipment to the shoulders, reducing the burden on the hands and keeping the operator comfortable during long-term operation, thus improving the user experience.

[0039] Finally, it should be noted that the rechargeable battery 30, negative pressure suction pump 34, and switch 23 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0040] When using the flower and fruit thinning air suction negative pressure picking head of this utility model, firstly, according to the height of the fruit tree and the operation requirements, use the threaded connection of the threaded connector 11 and the threaded hole 12 to assemble an appropriate number of holding rods 10 with the main body 1 of the negative pressure suction cup picking robot, put the rechargeable battery 30 into the heat dissipation battery box 3, and carry the equipment on the shoulder through the shoulder strap 321 to distribute the weight of the equipment.

[0041] Next, connect one end of the suction tube 35 to the main body 1 of the negative pressure suction cup picking robot through the flange, and connect the other end to the negative pressure suction pump 34 through the thread. Install the rubber bracket 2 on the bottom gripping rod 10 through the clamping chamber 20 and the clamping hole 21, and tighten the fastening screw 22 to fix it.

[0042] During operation, the operator holds the rubber bracket 2, presses the switch 23 to start the negative pressure suction pump 34, and the rechargeable battery 30 supplies power to generate negative pressure suction. By adjusting the angle of the grip rod 10, the main body 1 of the negative pressure suction cup picking robot is aligned with the flowers or young fruits to be removed to achieve negative pressure adsorption. Then, the operator holds the grip rod 10 to pull off the flowers or young fruits. After pulling them off, the negative pressure suction pump 34 works in reverse to blow off the flowers or young fruits adsorbed on the main body 1 of the negative pressure suction cup picking robot. If there are too long pipes, the pipe storage rack 36 on the back of the heat dissipation battery box 3 can be used with the binding rope to organize them and avoid the pipes interfering with the operation. After the operation is completed, the switch 23 is turned off, and the equipment is disassembled for storage or maintenance.
