Description

Technical Field

[0001] This utility model relates to the technical field of goji berry harvesting machines with adjustable harvesting distance, and more particularly to a goji berry harvesting machine with adjustable harvesting distance. Background Technology

[0002] Goji berry producing areas are mostly planted using trellis systems, resulting in scattered branches and fruit distribution, which places high demands on the adaptability of harvesting equipment. While existing handheld goji berry harvesters offer advantages such as flexible operation and adaptability to complex planting environments,…

[0003] Currently, handheld goji berry harvesters have the following drawbacks: the harvesting distance is fixed, and the operating radius cannot be adjusted according to actual needs. For goji berries that are high up, deep in the ground, or in the gaps between branches, the fixed-distance harvesting head is difficult to reach, requiring users to frequently move their position or bend over and stand on tiptoe to operate, which not only increases labor intensity but also makes it easy to miss berries. At the same time, the fixed-distance design cannot be adapted to goji berry orchards with different plant types and planting densities, resulting in a limited harvesting range and limited operating efficiency. Therefore, we have proposed a goji berry harvester with an adjustable harvesting distance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable picking distance goji berry harvesting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a goji berry harvester with adjustable harvesting distance, comprising a sleeve and an adjusting rod, wherein the sleeve and the adjusting rod are slidably sleeved together, a control end is fixedly connected to the outer end of the adjusting rod, a goji berry harvesting end is fixedly connected to the outer end of the sleeve, a control wire is fixedly connected between the goji berry harvesting end and the control end, a ring is fixedly sleeved on the outer wall of the sleeve, a fixing ring is provided on the outer wall of the ring, two handles are fixedly provided on one side of the fixing ring, a component ring is fixedly connected to the side of the ring, and a clamping component is provided on the component ring.

[0006] Preferably, the outer wall of the ring sleeve is provided with an annular limiting groove, and the fixed ring is rotatably sleeved in the limiting groove.

[0007] Preferably, the inner wall of the fixing ring is fixed with two mutually symmetrical compression rubber pads, and both ends of the compression rubber pads are arc-shaped.

[0008] Preferably, the outer wall of the ring is fixedly fitted with two mutually symmetrical fixing plates, and the ends of the fixing plates are fixedly connected with an integrated extension plate.

[0009] Preferably, the clamping assembly includes a sliding rod, a steel ball, a clamping end, and a return spring. Two clamping ends extending into the assembly ring are slidably mounted on the outer wall of the assembly ring. The ends of the two clamping ends that are close to each other are arc-shaped, and the ends of the two clamping ends that are far from each other are fixedly connected to a sliding rod. The ends of the two sliding rods respectively slide out of two extension plates and are fixedly connected to spherical steel balls. A return spring is sleeved between the extension plates and the clamping ends on the outer walls of the two sliding rods.

[0010] Preferably, the clamping assembly further includes a clamping rubber pad, and the two clamping ends that are close to each other are both fixedly connected with the clamping rubber pad.

[0011] The beneficial effects of this utility model are:

[0012] In use, this invention first pulls the spherical steel ball outward to release the clamping and fixing of the adjusting rod, and then pushes or pulls the sleeve and adjusting rod to adjust the working radius of the goji berry picking end according to the position of the goji berry fruit until the required distance is reached. This allows the picking head to easily reach goji berries in different positions without the need for the user to frequently change their standing position or make large body movements, effectively reducing labor intensity and reducing the occurrence of missed fruits due to the picking head not being able to reach them.

[0013] When in use, the handheld goji berry harvester with a fixed distance design cannot adapt to goji berry gardens with different plant types and planting densities, resulting in a limited harvesting range and low work efficiency. This harvester can flexibly adjust the working radius of the harvesting end according to the plant type and planting density of different goji berry gardens, thereby expanding the harvesting range, adapting to various complex planting environments, significantly improving work efficiency, and making the harvesting work more efficient and comprehensive.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, this relates to a goji berry harvester with adjustable harvesting distance, including a sleeve 1 and an adjusting rod 2. The sleeve 1 and the adjusting rod 2 are slidably connected, allowing them to slide relative to each other. During actual harvesting, when faced with goji berries of different heights, depths, and locations between branches, the user can easily push or pull the adjusting rod 2 relative to the sleeve 1 to flexibly change the working radius of the goji berry harvesting end 3, thereby improving the harvester's adaptability to different harvesting positions. This eliminates the need for the user to frequently change their standing position or perform large-scale physical movements, reducing labor intensity. This also reduces fruit loss due to the inability of the picking head to reach the fruit, improving the overall quality of picking. The outer end of the adjusting rod 2 is fixedly connected to the control end 4, and the outer end of the sleeve 1 is fixedly connected to the goji berry picking end 3. A control wire 5 is fixedly connected between the goji berry picking end 3 and the control end 4. The control end 4 transmits control signals through the control wire 5 to drive the goji berry picking end 3 to complete the picking action. The normal operation of the picking function is not affected during the distance adjustment process. A ring 6 is fixedly sleeved on the outer wall of the sleeve 1. A fixing ring 8 is provided on the outer wall of the ring 6. Two handles 9 are fixedly provided on one side of the fixing ring 8. A component ring 11 is fixedly connected to the side of the ring 6. A clamping component is provided on the component ring 11.

[0023] The outer wall of the ring sleeve 6 is provided with a circular limiting groove 7, and the fixing ring 8 is rotatably sleeved in the limiting groove 7.

[0024] Two symmetrically arranged compression rubber pads 10 are fixed to the inner wall of the fixing ring 8. Both ends of the compression rubber pads 10 are arc-shaped. When it is necessary to lock the adjusting rod 2, the compression rubber pads 10 on the inner wall of the fixing ring 8 are rotated to a specific position to apply pressure to the relevant components, thereby fixing the adjusting rod 2. The annular limiting groove 7 restricts the rotation trajectory of the fixing ring 8, ensuring that it will not deviate during rotation, making the locking operation more accurate. At the same time, this mating structure can withstand greater external forces, ensuring that the adjusting rod 2 will not loosen due to vibration or external impact during harvesting, thus improving the stability of the harvester.

[0025] Two symmetrical fixing plates 12 are fixedly installed on the outer wall of the ring 6, and an integrated extension plate 13 is fixedly connected to the end of the fixing plate 12.

[0026] The clamping assembly includes a sliding rod 14, steel balls 15, clamping ends 16, and a return spring 17. Two clamping ends 16 extending into the assembly ring 11 are slidably mounted on the outer wall of the assembly ring 11. The ends of the two clamping ends 16 that are close to each other are arc-shaped, and the ends of the two clamping ends 16 that are far apart are fixedly connected to the sliding rod 14. The ends of the two sliding rods 14 respectively extend slidably to the outside of two extension plates 13 and are fixedly connected to spherical steel balls 15. A return spring 17 is sleeved between the extension plates 13 and the clamping ends 16 on the outer wall of the two sliding rods 14. The sliding rod 14 in the component is fitted with a return spring 17 on its outer wall. When the working radius needs to be adjusted, the ball-shaped steel ball 15 is pulled outward, which drives the sliding rod 14 to move outward synchronously. At this time, the return spring 17 is compressed. After the distance adjustment is completed, the external force is released, and the return spring 17 will automatically push the sliding rod 14 inward using its own elastic force, so that the clamping end 16 returns to the clamping state of the adjusting rod 2. This automatic reset function makes the operation more convenient, without the need for the user to manually reset the clamping end 16, reducing the operation steps and improving work efficiency.

[0027] The clamping assembly also includes a clamping rubber pad 18. The clamping rubber pad 18 is fixedly connected to the ends of the two clamping ends 16 that are close to each other. The clamping rubber pad 18 is provided on the inner side of the clamping end 16 in the clamping assembly. When the clamping end 16 is in contact with the outer wall of the adjusting rod 2, the clamping rubber pad 18 can increase the friction between it and the adjusting rod 2, which can effectively prevent slippage between the adjusting rod 2 and the clamping end 16. Even if it is subjected to a large external force during the harvesting process, it can ensure that the adjusting rod 2 is always in a stable fixed state, thereby ensuring that the working distance of the harvesting end 3 is fixed and reliable, and improving the accuracy and stability of harvesting.

[0028] Working principle: When it is necessary to adjust the working distance of the goji berry picking end 3, first pull the spherical steel balls 15 outside the two extension plates 13 outward. The steel balls 15 drive the sliding rod 14 to move outward synchronously, thereby pulling the two clamping ends 16 inside the component ring 11 away from each other. At this time, the return spring 17 sleeved on the sliding rod 14 is compressed, releasing the clamping and fixing of the adjusting rod 2 and keeping it in the unlocked state. Hold the control end 4 or the adjusting rod 2 and push or pull the sliding sleeve 1 and the adjusting rod 2. Adjust the working radius of the goji berry picking end 3 according to the height, depth or branch gap position of the goji berry hanging fruit until the required distance is reached. After the distance adjustment is completed, apply force through the handle 9 on the fixed ring 8 to make the fixed ring 8 rotate along the annular limiting groove 7 on the outer wall of the ring sleeve 6. When the two symmetrical compression rubber pads 10 on the inner wall of the fixing ring 8 rotate to the position of the steel ball 15, they continuously compress the steel ball 15 as they rotate, forcing the sliding rod 14 to drive the two clamping ends 16 to move closer to each other until the clamping ends 16 are in contact with the outer wall of the adjusting rod 2 and locked. During the compression process, the compression rubber pads 10 undergo elastic deformation, which, together with the structural design of the spherical steel ball 15, ensures that the steel ball 15 does not shift after being subjected to force, thus achieving stable compression. At the same time, the clamping rubber pads 18 on the inner side of the clamping ends 16 increase the friction with the outer wall of the adjusting rod 2, effectively preventing slippage between the adjusting rod 2 and the clamping ends 16, and ensuring reliable distance fixation during the harvesting process.
