Abstract
Description
Technical Field
[0001] This invention relates to the field of picking tweezers, specifically a chili-picking tweezers that mimic human hands. Background Technology
[0002] There are many varieties of chili peppers, and when harvesting them, we pay more attention to their shape, size, physical characteristics, and plant growth posture, including the average diameter, length, and weight of the peppers. Some chili pepper varieties have a dispersed growth posture, which is not conducive to mechanical harvesting and can only be harvested manually; while other chili pepper varieties have a clustered growth pattern, which is advantageous for mechanized harvesting.
[0003] Currently, the header structure of domestic chili harvesters mainly uses a fixed roller with spring-loaded teeth for harvesting. The harvesting principle relies on the spring-loaded teeth striking the chilies as the roller rotates. The commonly used spring-loaded teeth are made of metal with a certain angle in the upper and middle sections, and a torsion spring structure at the base for torsional shock absorption. Due to the properties of metal, the teeth impact the chilies during rotation, potentially damaging the peel and increasing the harvest breakage rate. Furthermore, the angle of the spring-loaded teeth cannot be adjusted, making it difficult to adapt to different operating conditions. After long-term use, the teeth also require cleaning, which is quite troublesome. When harvesting chilies manually, the hand is first inserted into the plant to grasp the chilies and then gently pulled out. Because the human hand is relatively soft, the damage to the chilies is relatively small, but manual harvesting is inefficient and time-consuming for large-scale harvesting. Based on this, we propose a human-hand-inspired chili-harvesting spring-loaded tooth design. Summary of the Invention
[0004] The purpose of this invention is to provide a toothed, hand-like tool for picking chili peppers, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A type of chili pepper picking tool that mimics the action of a human hand includes:
[0007] A tooth root, wherein the tooth root is connected to a tooth joint, and the tooth joint is connected to a tooth tip;
[0008] A connecting assembly includes a rotating connecting mechanism, an adjusting mechanism, and a fixing mechanism. Two rotating connecting mechanisms are provided, each located at one end of the toothed joint and used to connect the tooth root and the tooth tip to the toothed joint. The adjusting mechanism is used to adjust the bending angle between the tooth root, the toothed joint, and the tooth tip. The fixing mechanism is used to relatively fix the relative positions between the tooth root, the toothed joint, and the tooth tip.
[0009] A friction assembly disposed at the tooth root, the tooth pitch, and the tooth tip, and used to increase the frictional force at the tooth root, the tooth pitch, and the tooth tip; and
[0010] A cleaning assembly includes an energy storage mechanism and an air blowing mechanism. The energy storage mechanism is disposed inside the tooth root and the tooth spur and is used to store air when relative rotation occurs between the tooth root, the tooth spur and the tooth tip. The air blowing mechanism is used to clean the tooth root, the tooth spur and the tooth tip using the air stored in the energy storage mechanism.
[0011] Preferably, the rotating connection mechanism includes a ball groove and a ball head. The two ends of the toothed segment are respectively provided with a ball groove and a ball head. The ball head provided on the toothed segment and the ball groove provided on the tooth root are connected to each other, and the ball groove provided on the toothed segment and the ball head provided on the tooth tip are hinged to each other.
[0012] Preferably, the adjusting mechanism includes a return spring, which is disposed in the ball groove and connected to the ball head.
[0013] Preferably, the ball groove is provided with a fixing threaded hole, and the fixing mechanism includes a locking bolt, the locking bolt and the fixing threaded hole cooperating with each other.
[0014] Preferably, the friction assembly includes a protrusion disposed on the tooth root, the tooth pitch and the tooth tip and used to increase the friction force of the tooth root, the tooth pitch and the tooth tip.
[0015] Preferably, the ball groove has a movable groove, and the energy storage mechanism includes a flexible shaft, a piston head, a piston cylinder, and a cylinder. The flexible shaft is disposed in the movable groove and connected to the ball head. The piston head is connected to the flexible shaft, the piston cylinder is connected to the movable groove, and the piston head is connected to the piston cylinder. A cylinder is disposed at one end of the piston cylinder.
[0016] Preferably, both the tooth root and the tooth spur are provided with storage grooves, and the cylinder is disposed in the storage grooves.
[0017] Preferably, both the tooth root and the tooth segment are provided with mounting grooves. The air blowing mechanism includes a telescopic rod, a mounting block, a pressure relief valve, and a retraction spring. The telescopic rod is disposed in the mounting groove, the retraction spring is disposed inside the telescopic rod, the mounting block is disposed at the top of the telescopic rod, and the pressure relief valve is disposed in the mounting block.
[0018] Preferably, the pressure relief valve is connected to the bottom and side wall of the mounting block, respectively.
[0019] Preferably, a rubber block is provided on the top of the mounting block.
[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: When in use, the position of the tooth root, tooth segment, and tooth tip can be adjusted by rotating the connecting mechanism, and then the relative position between the tooth root, tooth segment, and tooth tip can be fixed by the fixing mechanism. This simulates the bending state of a human hand during harvesting, making it easier to adjust the harvesting angle to adapt to the harvesting of different types of peppers. When harvesting peppers with thin and easily broken skins, the restriction of the fixing mechanism on the rotating connecting mechanism can be removed. After each harvest, the tooth root, tooth segment, and tooth tip can be adjusted by the adjusting mechanism. By adjusting the relative positions of the three components and resetting them, the impact of the picking teeth (including the root, segment, and tip) on the pepper peel during harvesting can be reduced, thus minimizing damage to the pepper peel. When the adjustment mechanism adjusts the position between the root, segment, and tip of the teeth, the piston in the energy storage mechanism reciprocates along the piston cylinder, storing air in the cylinder. When the air pressure reaches the set pressure of the pressure relief valve, it blows on the outer surfaces of the root, segment, and tip of the teeth, cleaning them. This method is highly practical and worth promoting. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] Please see Figure 1-4 The present invention provides a technical solution:
[0028] A type of chili pepper picking tool that mimics the action of a human hand, as shown in the instruction manual. Figure 1As shown, it includes:
[0029] Tooth root 1, tooth root 1 is connected to tooth segment 2, tooth segment 2 is connected to tooth tip 3, tooth root 1 is used to connect the present application and the drum of the chili harvester to each other, tooth segment 2 and tooth tip 3 are both used to install friction components and cleaning components, tooth root 1, tooth segment 2 and tooth tip 3 are all made of polyethylene plastic.
[0030] The connecting assembly includes a rotating connecting mechanism, an adjusting mechanism, and a fixing mechanism. There are two rotating connecting mechanisms, which are respectively located at both ends of the toothed joint 2 and are used to connect the tooth root 1 and the tooth tip 3 to the toothed joint 2. The adjusting mechanism is used to adjust the bending angle between the tooth root 1, the toothed joint 2, and the tooth tip 3. The fixing mechanism is used to fix the relative positions of the tooth root 1, the toothed joint 2, and the tooth tip 3.
[0031] The rotating connection mechanism includes a ball groove 4 and a ball head 5. The ball groove 4 is used to fix the ball head 5 and restrict its movement. As shown in the attached figure of the instruction manual, the two ends of the toothed joint 2 are respectively provided with a ball groove 4 and a ball head 5. The ball head 5 provided on the toothed joint 2 and the ball groove 4 provided on the tooth root 1 are connected to each other. The ball groove 4 provided on the toothed joint 2 and the ball head 5 provided on the tooth tip 3 are hinged to each other. The ball groove 4 and the ball head 5 are fastened together by fastening bolts and fastening seats (with tooth root 1, toothed joint 2 or tooth tip 3).
[0032] The adjustment mechanism includes a return spring 6, which is a tension spring. The return spring 6 is set in the ball groove 4 and fixedly connected to the ball head 5. The return spring 6 is used to drive the ball head 5 to return to its original position after relative rotation occurs between the ball head 5 and the ball groove 4 (at this time, the fixing mechanism does not fix the relative position between the ball head 5 and the ball groove 4).
[0033] The ball groove 4 is provided with a fixing threaded hole, which is used to cooperate with the locking bolt 7. The fixing mechanism includes the locking bolt 7, which cooperates with the fixing threaded hole to fix the ball head 5. By rotating the locking bolt 7, the relative position between the ball head 5 and the ball groove 4 is fixed. The locking bolts 7 are symmetrically arranged on both sides of the ball groove 4. In use, the movement of the ball head 5 can be restricted by clamping the ball head 5 with the locking bolts 7 on both sides.
[0034] A friction assembly is disposed on the tooth root 1, tooth joint 2, and tooth tip 3 to increase the surface friction of the tooth root 1, tooth joint 2, and tooth tip 3; the friction assembly includes protrusions 8, which are made of rubber material and are staggered on the tooth root 1, tooth joint 2, and tooth tip 3. The protrusions 8 are disposed on the tooth root 1, tooth joint 2, and tooth tip 3 to increase the friction when the tooth root 1, tooth joint 2, and tooth tip 3 come into contact with the surface of the chili pepper.
[0035] The cleaning component includes an energy storage mechanism and an air blowing mechanism. The energy storage mechanism is located inside the tooth root 1 and tooth segment 2 and is used to store air when relative rotation occurs between the tooth root 1, tooth segment 2 and tooth tip 3. The air blowing mechanism is used to clean the tooth root 1, tooth segment 2 and tooth tip 3 using the air stored in the energy storage mechanism. The setting of the energy storage mechanism can further increase the resistance of the tooth root 1, tooth segment 2 and tooth tip 3 when they rotate, thereby increasing the harvesting efficiency of chili peppers.
[0036] The ball groove 4 has a moving groove, which restricts the movement of the flexible shaft 10 so that it can only move along the flexible shaft 10. The energy storage mechanism includes the flexible shaft 10, piston head 11, piston cylinder 12 and cylinder 13. The flexible shaft 10 is a steel bar made of carbon steel, and has the characteristics of being easy to bend radially and not easily deformed axially, so it can be used for a long time. The flexible shaft 10 is set in the moving groove and connected to the ball head 5. The two ends of the flexible shaft 10 are fixedly connected to the ball head 5 and the piston head 11, respectively. The piston head 11 is connected to the flexible shaft 10 and is made of nitrile rubber. The piston cylinder 12 is connected to the moving groove. The piston cylinder 12 is equipped with a one-way air valve, which only allows the outside air to flow into the piston cylinder 12 in one direction. The piston head 11 is connected to the piston cylinder 12. One end of the piston cylinder 12 is equipped with a cylinder 13. The connection end between the cylinder 13 and the piston cylinder 12 is also equipped with a one-way air valve. This one-way air valve is used to ensure that air can only enter the cylinder 13 from the piston cylinder 12. Both the tooth root 1 and the tooth spur 2 are provided with storage slots, which are used to store the cylinder 13, and the cylinder 13 is placed in the storage slots.
[0037] Both the tooth root 1 and the tooth joint 2 are provided with mounting grooves 14. The air blowing mechanism includes a telescopic rod 15, a mounting block 16, a pressure relief valve 17, and a contraction spring 18. The telescopic rod 15 is set in the mounting groove 14. As shown in the attached figure of the specification, the bottom of the telescopic rod 15 is connected to the cylinder 13. Therefore, after the cylinder 13 is filled with enough gas, the telescopic rod 15 will extend, thereby pushing the side pressure relief valve 17 to the outside of the mounting groove 14. The contraction spring 18 is set inside the telescopic rod 15. The contraction spring 18 is also a tension spring. The mounting block 16 is set at the top of the telescopic rod 15. The pressure relief valve 17 is set in the mounting block 16. In this embodiment, the opening air pressure of the pressure relief valve 17 is 30 PSI, and the closing air pressure of the pressure relief valve 17 is 15 PSI.
[0038] Pressure relief valves 17 are connected to the bottom and side wall of mounting block 16 respectively. The pressure relief valve 17 located at the bottom of mounting block 16 is used to clean the inside of mounting groove 14 when it is opened, and the pressure relief valve 17 located on the side wall is used to clean the outside of tooth root 1, tooth joint 2 and tooth tip 3 when it is opened.
[0039] The top of the mounting block 16 is provided with a rubber block 19, so that when the telescopic rod 15 is not lifted by air pressure, the rubber block 19 is used to increase the friction when the tooth root 1, tooth joint 2, and tooth tip 3 come into contact with the surface of the chili pepper.
[0040] Working principle: When using this application, the appropriate type of chili pepper can be selected. When the harvested chili pepper has a thick skin and is not easily broken, the angle between the ball head 5 and the ball groove 4 can be adjusted according to the size of the fruit, thereby adjusting the angle between the tooth root 1, tooth segment 2, and tooth tip 3. After adjustment, the ball head 5 can be fixed by locking bolt 7 and then it can be used.
[0041] When the harvested chili peppers have thin skins that are easily broken, loosen the locking bolt 7. At this time, due to the connection of the return spring 6, the ball head 5 will still move as per the instruction manual without external force. Figure 1 As configured, when the tooth tip 3 or tooth segment 2 contacts the chili pepper, the adjacent tooth tip 3 or tooth segment 2 (or tooth tip 3 and tooth segment 2) will rotate to a certain extent. However, due to the restriction of the return spring 6, the chili pepper and chili pepper plant are separated from each other. The return spring 6 will drive the tooth tip 3 or tooth segment 2 (or tooth tip 3 and tooth segment 2) to return to its original position, which will not affect the harvesting of the next chili pepper. When harvesting chili peppers with thinner skin, when the return spring 6 drives the ball head 5 to reciprocate, the ball head 5 will drive the flexible shaft 10 to move, thereby driving the piston to reciprocate along the piston cylinder 12. When the piston reciprocates along the piston cylinder 12, it will fill the cylinder 13 with gas. As the gas is filled, it will lift the telescopic rod 15. When the pressure reaches the opening pressure of the pressure relief valve 17, the pressure relief valve 17 will open and clean the mounting groove 14, tooth root 1, tooth segment 2 and outer surface of tooth tip 3.
[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
