Description

Technical Field

[0001] This utility model relates to the field of seed grasping technology, specifically a handheld seed grasping device with a negative pressure suction soft capsule. Background Technology

[0002] Seeds are the reproductive bodies of plants, composed of the seed coat, embryo, and endosperm. They serve the function of perpetuating the species and are widely used in agriculture (foods, oilseeds, cotton), medicine (such as almonds), industry (oil extraction, cosmetic raw materials), and ecological restoration. In scenarios such as seed screening, sorting, transplanting, or laboratory research, seeds must be handled precisely to avoid damaging their fragile structure or slipping due to their smooth surface, thereby ensuring germination rate and operational efficiency.

[0003] Currently, in the process of seed screening, sorting, or transplantation, traditional tools mostly use tweezers to pick up seeds. However, when tweezers pick up seeds, the hard gripper directly contacts the seeds, which can easily cause mechanical damage. Moreover, for seeds with smooth surfaces or irregular shapes, the tweezers are prone to slipping due to insufficient friction, resulting in low operating efficiency. In addition, the gripping opening of traditional tweezers is fixed, making it difficult to flexibly adjust the gripping range, which leads to the need to frequently change tools for seeds with large differences in size. To address this, we propose a handheld seed picking device with a negative pressure suction soft capsule. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a handheld seed gripping device with a negative pressure suction soft capsule. Through the linkage design of three sets of flexible leather soft capsules and gripping claws, the gripping claws wrap around the seed surface, avoiding damage from hard contact. The inner diameter of the gripping claws can be dynamically adjusted through the radial movement structure of the slider and slide rail. The flexible material of the leather soft capsules and the anti-slip strip design significantly improve the friction, thus solving the problems mentioned above.

One end of the solenoid valve 15 inside the mounting box 3 is connected to the main air pipe 10, and the other end is connected to three sets of bronchial pipes 16. When the solenoid valve 15 is activated, the negative pressure gas introduced by the main air pipe 10 enters the bottom of the soft capsule 5 through the three sets of bronchial pipes 16, causing the soft capsule 5 to contract and generate radial inward pulling force. The three sets of sliders 22 slide along the three sets of sliding grooves 14 at the top of the mounting box 3. At the same time, the slide rail 21 is embedded in the sliding groove 23 on the side of the slider 22 to ensure that the slider 22 moves accurately towards the center. The three sets of clamping claws 4 fixed at the top of the slider 22 contract synchronously, and the soft capsule 5 between the two clamping claws 4 forms a clamping space to wrap the seeds.

[0029] The top of the mounting plate 2 has several slots 17, and the bottom of the mounting box 3 is fixedly connected with several buckles 24. The buckles 24 are engaged with the slots 17, and the buckles 24 at the bottom of the mounting box 3 are engaged with the slots 17 at the top of the mounting plate 2, so as to realize the quick disassembly and replacement of the mounting box 3.

[0030] Pressure sensors 7 are installed on the inner sides of the three sets of gripping claws 4. The pressure sensors 7 installed on the inner sides of the three sets of gripping claws 4 detect the gripping force in real time and feed the signal back to the control system to prevent the seeds from being damaged due to excessive gripping.

[0031] Several anti-slip strips 6 are fixedly connected to the inner sides of the three sets of gripping claws 4. The anti-slip strips 6 on the inner side of the gripping claws 4 increase friction and effectively prevent smooth seeds from slipping off during the gripping process.

[0032] A switch button 8 is installed on the front side of the handle 1, and a relay 18 is installed on the front side inside the handle 1.

[0033] An adjustment knob 12 is installed on the left side of the handle 1. The adjustment knob 12 on the left side of the handle 1 is used to adjust the negative pressure intensity and optimize the gripping effect of different seeds.

[0034] A placement slot 9 is provided on the right side of the handle 1. The main air pipe 10 is snapped into the placement slot 9 on the right side of the handle 1 to fix the position of the air passage and prevent bending or loosening during use.

[0035] A battery 19 is installed on the bottom inside the handle 1. A charging port 20 is provided at the bottom of the handle 1. The main air tube 10 is snapped into the placement slot 9 on the right side of the handle 1 to fix the air passage position and prevent bending or loosening during use.

[0036] Several anti-slip strips 11 are fixedly connected to the rear side of the handle 1. The anti-slip strips 11 on the rear side of the handle 1 improve the grip stability during operation and reduce the risk of slipping.

[0037] An LED light 13 is installed on the top center of the mounting box 3. The LED light 13 on the top center of the mounting box 3 is powered by a battery 19 and provides clear illumination for seed picking in low light conditions.

[0038] The following describes the specific operation process of a handheld seed-grabbing device with a negative pressure suction soft capsule provided by this utility model in grasping seeds.

[0039] When using this handheld seed-grabbing device with a negative pressure suction soft capsule, the buckle 24 at the bottom of the mounting box 3 engages with the slot 17 on the mounting plate 2 at the top of the handle 1, thereby fixing the mounting box 3. One end of the solenoid valve 15 inside the mounting box 3 is connected to the main air pipe 10, and the other end is connected to three sets of bronchial pipes 16. The switch button 8 on the front of the handle 1 controls the on / off of the relay 18, and the solenoid valve 15 is opened and closed by an electrical signal to realize the opening and closing of the negative pressure.

[0040] When the solenoid valve 15 is activated, the negative pressure gas introduced by the main air pipe 10 enters the bottom of the cortical soft bag 5 through the three sets of bronchial pipes 16, causing the cortical soft bag 5 to contract and generate radial inward pulling force. The three sets of sliders 22 slide along the three sets of sliding grooves 14 on the top of the mounting box 3. At the same time, the slide rail 21 is embedded in the sliding groove 23 on the side of the slider 22 to ensure that the slider 22 moves accurately towards the center. The three sets of clamping claws 4 fixed on the top of the slider 22 contract synchronously. The cortical soft bag 5 between the two sets of clamping claws 4 forms a clamping space to wrap the seeds. The pressure sensor 7 installed on the inner side of the three sets of clamping claws 4 detects the clamping force in real time and feeds the signal back to the control system. The adjustment knob 12 on the left side of the handle 1 is used to adjust the negative pressure intensity, optimize the clamping effect of different seeds, and prevent the seeds from being damaged due to excessive clamping.
