Description

Technical Field

[0001] This utility model relates to the field of agricultural harvesting machinery technology, specifically a chayote shoot harvesting anti-damage clamp. Background Technology

[0002] Chayote shoots, also known as dragon's beard vegetables, are a popular specialty vegetable in recent years. They are favored by the market as a healthy food due to their crisp and tender texture, low fiber content, and rich nutrition. The best time to eat them is when the new shoots are 10-15 cm long. At this stage, the tissues are not yet mature, the cell walls are thin, and the water content is as high as 78%-86%. After harvesting, they are very easy to cause chlorophyll decomposition, tissue softening, and even rotting due to physical damage, which seriously reduces the quality. Currently, the harvesting of chayote shoots mainly relies on general-purpose clamping tools. Existing clamping devices generally adopt rigid clamping structures and have not been designed with force control mechanisms adapted to the characteristics of shoots. The clamping force of these devices depends entirely on the operator's experience and hand control, which has significant technical defects. The stem diameter of chayote shoots is only 1-2.0mm, similar to that of tea shoots. During the bending process, there is a clear range of pressure changes. Once the critical value is exceeded, irreversible damage occurs. When the clamping force approaches the damage threshold, the operator cannot detect it in time. At the same time, most general clamps are flat clamping designs, which do not fit well with the cylindrical shape of chayote shoots. The local pressure concentration further aggravates the risk of damage. Although some tea shoot picking tools have attempted flexible designs, they have not solved the problem of real-time force monitoring and cannot be directly adapted to the chayote shoot harvesting scenario. Utility Model Content

[0003] The purpose of this utility model is to provide a chayote shoot harvesting anti-damage clamp to solve the problems mentioned in the background art, where the clamping force of the existing clamps relies on manual experience control, resulting in a lack of force control precision, no damage warning mechanism, and poor fit with the shoot shape, which easily causes the shoots to be pinched and the harvesting damage rate to be high.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a chayote shoot harvesting and damage prevention clamp, comprising a gripping frame, a functional ring fixedly connected to one end of the gripping frame, a power supply module fixedly installed at the end of the gripping frame connected to the functional ring, a clamping plate rotatably mounted inside the functional ring, and the other end of the clamping plate penetrating the outer surface of the functional ring, a contact block fixedly provided on the outer surface of the end of the clamping plate located inside the functional ring, a rotating ring installed inside the functional ring, and a pressing block fixedly provided on the outer surface of the rotating ring, a contact groove opened on the outer surface of one end of the rotating ring, a clearance groove opened on the outer surface of the end of the functional ring connected to the gripping frame, a sliding displacement plate installed on the inner surface of the end of the gripping frame connected to the functional ring, and a rotating guide wheel installed on the inner surface of the end of the gripping frame connected to the functional ring, a sliding lifting plate installed on the end of the gripping frame away from the functional ring, and a connecting rope fixedly connected to the outer surface of the lifting plate, and the other end of the connecting rope passing around the outer surface of the guide wheel and fixedly connected to one end of the displacement plate; A rotating contact plate is installed on the outer surface of one end of the clamping plate, and a rotating contact wheel is installed on one end of the contact plate. A limit plate is fixedly installed on the outer surface of the end of the clamping plate that is connected to the contact plate. A pressure sensor is fixedly installed on the upper end of the clamping plate facing the contact plate, and a warning light is fixedly installed on the other side of the upper end of the clamping plate.

[0005] Preferably, a spring is connected between the clamping plate and the functional ring, and the clamping plate is distributed at equal angles on the surface of the functional ring, and a notch is provided at one end of the functional ring.

[0006] By adopting the above technical solution, the elasticity of the spring allows the clamping plate to automatically reset, which facilitates the insertion and removal of tender shoots. The clamping plates with equal angles can apply clamping force to the tender shoots evenly, and the notch design of the functional ring provides a convenient insertion channel for the tender shoots.

[0007] Preferably, a spring is connected between one end of the rotating ring and the functional ring, the extrusion block is designed as a right-angled trapezoid, the inclined surface of the extrusion block faces the contact block, and the extrusion block and the contact block are arranged in a one-to-one correspondence.

[0008] Using the above technical solution, the spring between the rotating ring and the functional ring can automatically reset the rotating ring when it is not subjected to external force. The right-angled trapezoidal extrusion block can smoothly push the contact block through the inclined surface to realize the contraction of the clamping plate. Moreover, the one-to-one correspondence between the extrusion block and the contact block ensures the consistency of the action of each clamping plate.

[0009] Preferably, the contact groove and the relief groove are staggered, and the vertical projections of the contact groove and the relief groove coincide. The displacement plate is designed as a right trapezoid, and the vertical projection of the displacement plate completely coincides with the vertical projection of the relief groove. The inclined surface of the displacement plate faces upward toward the inner surface of the contact groove. A spring connects the lifting plate and the grip frame.

[0010] By adopting the above technical solution, the misalignment and partial overlap design of the contact groove and the clearance groove, combined with the right-angled trapezoidal structure of the displacement plate, allows the displacement plate to accurately drive the rotating ring to rotate when it slides, thereby controlling the opening and closing of the clamping plate. The spring between the lifting plate and the gripping frame can make the lifting plate automatically reset, which is convenient for operators to operate multiple times and reduces labor intensity.

[0011] Preferably, the limiting plate is L-shaped, with the upper end of the limiting plate fitting against the lower end of the contact plate, and the end of the limiting plate fitting against the contact plate and the pressure sensor are located on opposite sides of the contact plate.

[0012] By adopting the above technical solution, the L-shaped limiting plate can limit the rotation angle of the contact plate, ensuring that the contact plate fits the tender shoot within a suitable range. Furthermore, the limiting plate and the pressure sensor are located on opposite sides of the contact plate, avoiding interference from the limiting plate to the pressure sensor and ensuring the accuracy of pressure detection.

[0013] Preferably, the pressure sensor is electrically connected to the warning light and the power supply module via a cable, and one end of the pressure sensor is in contact with the outer surface of the contact plate.

[0014] Using the above technical solution, the pressure sensor is electrically connected to the warning light and power supply module via a cable, which can transmit the pressure signal of the contact plate on the tender shoot to the warning light in real time. When the pressure approaches the damage threshold, the warning light will light up to provide an early warning. The power supply module provides power to the pressure sensor and the warning light, ensuring the stable operation of the force control system.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the chayote shoot harvesting anti-damage clamp: 1. The pressure sensor monitors the pressure of the contact plate and contact wheel on the tender shoot in real time. When the pressure approaches the damage threshold, a signal is immediately sent to the warning light via cable. The warning light illuminates to remind the operator and avoid damage to the tender shoot due to excessive clamping force caused by insufficient human experience. The power supply module provides power to the pressure sensor and warning light to ensure the stable operation of the force control system. 2. The contact plate and contact wheel, which are rotatably installed at one end of the clamping plate with equal angles, can adaptively fit the cylindrical shape of the chayote shoot. Compared with the traditional planar clamping design, it disperses the clamping pressure and avoids local pressure concentration. The limiting plate limits the contact plate to ensure that it fits the shoot within a suitable angle range, further improving the clamping stability and safety. 3. Through the transmission structure consisting of a lifting plate, connecting rope, and guide wheel, the operator can control the rotation of the rotating ring and the squeezing block by pulling the lifting plate, which in turn drives the displacement plate to slide via the connecting rope. When the rotating ring rotates, the squeezing block pushes the contact block, causing the clamping plate to contract towards the center to achieve clamping, thus realizing the opening and closing control of the clamping plate. The spring between the lifting plate and the gripping frame can automatically reset when not in operation, facilitating the next operation, reducing labor intensity, and improving harvesting efficiency.

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.

[0019] Please see Figures 1-6 This utility model provides a technical solution: a chayote shoot harvesting and damage prevention clamp.

[0020] Example 1: This example discloses a gripping frame 1, with a functional ring 2 fixedly connected to one end of the gripping frame 1. A power supply module 3 is fixedly installed at the end of the gripping frame 1 connected to the functional ring 2. One end of a clamping plate 4 is rotatably installed inside the functional ring 2, and the other end of the clamping plate 4 penetrates through the outer surface of the functional ring 2. A contact block 5 is fixedly provided on the outer surface of the end of the clamping plate 4 located inside the functional ring 2. A rotating ring 6 is installed inside the functional ring 2, and a pressing block 7 is fixedly provided on the outer surface of the rotating ring 6. A [missing information - likely a design feature] is opened on the outer surface of one end of the rotating ring 6. The contact groove 8, the outer surface of the end where the functional ring 2 is connected to the grip 1 is provided with a clearance groove 9, the inner surface of the end where the grip 1 is connected to the functional ring 2 is provided with a sliding displacement plate 10, and the inner surface of the end where the grip 1 is connected to the functional ring 2 is provided with a rotating guide wheel 11. The end of the grip 1 away from the functional ring 2 is provided with a sliding lifting plate 12, and the outer surface of the lifting plate 12 is fixedly connected to one end of a connecting rope 13, and the other end of the connecting rope 13 passes around the outer surface of the guide wheel 11 and is fixedly connected to one end of the displacement plate 10. A spring is connected between the clamping plate 4 and the functional ring 2, and the clamping plate 4 is evenly distributed on the surface of the functional ring 2, and a notch is provided at one end of the functional ring 2; A spring is connected between one end of the rotating ring 6 and the functional ring 2. The extrusion block 7 is designed as a right-angled trapezoid, and the inclined surface of the extrusion block 7 is set towards the contact block 5. The extrusion block 7 and the contact block 5 are set in a one-to-one correspondence. The contact groove 8 and the clearance groove 9 are offset, and the vertical projections of the contact groove 8 and the clearance groove 9 overlap. The displacement plate 10 is a right trapezoidal design, and the vertical projection of the displacement plate 10 completely overlaps with the vertical projection of the clearance groove 9. The inclined surface of the displacement plate 10 is set upward toward the inner surface of the contact groove 8. A spring connects the lifting plate 12 and the grip 1. The gripping frame 1 is fixedly connected to the functional ring 2. The clamping plate 4 is connected to the functional ring 2 through a spring and is in a naturally open state. The notch at one end of the functional ring 2 facilitates the insertion of tender shoots. The rotating ring 6 is connected to the functional ring 2 through a spring. The squeezing block 7 does not contact the contact block 5. The displacement plate 10 is located in the relief groove 9. The lifting plate 12 is reset under the action of the spring. When in use, the operator pulls the lifting plate 12, and the connecting rope 13 changes direction through the guide wheel 11, pulling the displacement plate 10 to slide along the inner side of the grip frame 1. The right-angled trapezoidal inclined surface of the displacement plate 10 contacts the inner side of the contact groove 8, pushing the rotating ring 6 to rotate against the spring resistance. When the rotating ring 6 rotates, the squeezing block 7 pushes the contact block 5 through the inclined surface, causing the clamping plate 4 to contract around the internal rotating axis of the functional ring 2. The clamping plates 4, which are distributed at equal angles, move towards the center at the same time to form an encirclement of the tender shoot. After the lifting plate 12 is released, the spring drives the lifting plate 12 and the displacement plate 10 to reset. The rotating ring 6 reverses under the action of the spring, the squeezing block 7 separates from the contact block 5, and the clamping plate 4 opens under the action of the spring, completing one clamping cycle.

[0021] Example 2: This example is based on Example 1: A rotating contact plate 14 is installed on the outer surface of one end of the clamping plate 4, and a rotating contact wheel 15 is installed on one end of the contact plate 14. A limit plate 16 is fixedly provided on the outer surface of the end of the clamping plate 4 connected to the contact plate 14. A pressure sensor 17 is fixedly installed on the side of the upper end of the clamping plate 4 facing the contact plate 14, and a warning light 18 is fixedly installed on the other side of the upper end of the clamping plate 4. The limiting plate 16 is L-shaped, and the upper end of the limiting plate 16 is attached to the lower end of the contact plate 14. The end of the limiting plate 16 that is attached to the contact plate 14 and the pressure sensor 17 are located on both sides of the contact plate 14, respectively. The pressure sensor 17 is electrically connected to the warning light 18 and the power supply module 3 via a cable, and one end of the pressure sensor 17 is in contact with the outer surface of the contact plate 14. When the clamping plate 4 retracts, the contact plate 14 contacts the cylindrical surface of the tender shoot through the contact wheel 15. The contact plate 14 rotates around the clamping plate 4 and disengages from the limiting plate 16. During the rotation of the contact plate 14, it squeezes the pressure sensor 17. The pressure sensor 17 transmits the signal to the warning light 18 through the cable. The power supply module 3 supplies power to it. When the pressure of the pressure sensor 17 pressed by the contact plate 14 approaches the tender shoot damage threshold, the pressure sensor 17 triggers the warning light 18 to light up, reminding the operator to reduce the pulling force and avoid excessive clamping force. At this time, the operator only needs to maintain the pressure to prevent the cell wall of the tender shoot from rupturing. The rolling design of the contact wheel 15 reduces friction during clamping. Combined with the adaptive rotation of the contact plate 14, the clamping force is evenly distributed. The limiting plate 16 and the pressure sensor 17 are located on both sides of the contact plate 14, which not only limits its rotation range but also ensures accurate transmission of pressure signals.
