A hydraulic multi-way valve suitable for high-frequency vibratory harvesters

Abstract

This utility model relates to the field of harvester technology, and more particularly to a hydraulic multi-way valve suitable for high-frequency vibration harvesters. It mainly addresses the problem that the valve and oil circuit of the hydraulic rod, after being fixed, can loosen due to vibration. The proposed technical solution includes a housing, inside which a hydraulic rod is housed. The output end of the hydraulic rod passes through the housing, and a harvesting clamp is located outside the output end of the housing. A rotating block is fixedly connected to the hydraulic rod away from the output end, and support rods are rotatably connected to both sides of the rotating block. This utility model uses a positioning sleeve outside the screw to position the screw. Even if the screw vibrates, the positioning sleeve is restricted by a paddle between positioning plates, while the positioning plates are fixed by a positioning ring and a positioning block. This restricts the rotation of the screw, preventing loosening caused by hydraulic rod vibration, and improving the stability of the screw within the support rods and rotating block.

Description

Technical Field

[0001] This utility model relates to the field of harvester technology, and in particular to a hydraulic multi-way valve suitable for high-frequency vibration harvesters. Background Technology

[0002] A harvester is a mechanical device used to harvest crops. It is mainly used to replace manual labor in harvesting fruits or tea leaves, thereby improving efficiency and reducing labor costs. However, harvesters require high-frequency vibration during harvesting to avoid damaging branches.

[0003] During harvesting, hydraulic rods are used to extend and retract, thereby controlling the harvesting claws to pick up the fruit or tea leaves. After the harvesting claws clamp the fruit or tea leaves, they are picked off through high-frequency vibration.

[0004] However, during high-frequency vibration, the valves and oil circuits of the hydraulic rod, once fixed, can loosen due to vibration. This necessitates periodic tightening of the screw, affecting harvesting efficiency. Therefore, this invention proposes a hydraulic multi-way valve suitable for high-frequency vibration harvesters. Utility Model Content

[0005] The purpose of this invention is to address the problem in the background technology that when there is high-frequency vibration, the valves and oil circuits of the hydraulic rod will loosen due to vibration after being fixed, which leads to the need for periodic tightening of the screw and affects the harvesting efficiency. The invention proposes a hydraulic multi-way valve suitable for high-frequency vibration harvesting machines.

[0006] The technical solution of this utility model: A hydraulic multi-way valve suitable for a high-frequency vibrating harvester, comprising a housing, a hydraulic rod disposed inside the housing, the output end of the hydraulic rod passing through the housing, a harvesting clamp disposed outside the output end of the housing, a rotating block fixedly connected to the hydraulic rod away from the output end, and support rods rotatably connected to both sides of the rotating block, the support rods being fixedly connected inside the housing;

[0007] The support rod and the rotating block are equipped with a screw rod inside, one end of which is rotatably connected to a nut, and an anti-slip pad is provided on the outside of the screw rod away from the nut.

[0008] A positioning sleeve is fitted onto the outside of the screw near the anti-slip pad, and a positioning component is provided on the outside of the positioning sleeve.

[0009] Optionally, the positioning component includes paddles, a plurality of which are arranged in a circumferential array outside the positioning sleeve, and positioning pieces are disposed between the paddles.

[0010] Optionally, a positioning ring is fixedly connected to the end of the positioning piece away from the lever, and a positioning block is slidably connected to the outside of the positioning ring, with the positioning block fixedly connected to one side of the support rod.

[0011] Optionally, the output end of the hydraulic rod abuts against a push plate, and a groove is provided inside the push plate, with the picking clip slidably connected inside the groove.

[0012] Optionally, the chute is inclined, one end of the picking clip is rotatably connected to one side of the housing, and the outer part of the picking clip is wider away from the housing.

[0013] Optionally, a retrieval opening is provided on the outside of the housing near the support rod, and a cover plate is provided on the top of the housing.

[0014] Optionally, a connecting bolt is rotatably connected inside the push plate near the center position, and the connecting bolt is rotatably connected inside the hydraulic rod output end.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] This invention uses a positioning sleeve on the outside of the screw to position the screw. Even if the screw vibrates, the positioning sleeve is restricted by the locating plate between the positioning pieces, and the positioning pieces are fixed by the positioning ring and the positioning block. This restricts the rotation of the screw, avoids the screw from loosening due to the vibration of the hydraulic rod, and improves the stability of the screw inside the support rod and the rotating block.

[0029] Example

[0030] like Figure 2 , Figure 4 and Figure 5As shown, this utility model proposes a hydraulic multi-way valve suitable for a high-frequency vibrating harvester, comprising a housing 1, a hydraulic rod 5 disposed inside the housing 1, the output end of the hydraulic rod 5 passing through the housing 1, and a harvesting clamp 14 disposed outside the output end of the housing 1. The hydraulic rod 5 inside the housing 1 can control the harvesting clamp 14 to perform clamping vibration. A rotating block 4 is fixedly connected to the hydraulic rod 5 away from the output end, and support rods 2 are rotatably connected to both sides of the rotating block 4. The hydraulic rod 5 can be easily disassembled and installed by rotating the rotating block 4 between the support rods 2. The support rods 2 are fixedly connected to... Inside the housing 1, the support rod 2 can fix the rotating block 4 and the hydraulic rod 5 inside the housing 1; a screw 3 is provided inside the support rod 2 and the rotating block 4, and a nut 6 is rotatably connected to one end of the screw 3. The nut 6 allows the screw 3 to connect the rotating block 4 between the support rods 2. An anti-slip pad 7 is provided on the outside of the screw 3 away from the nut 6. The anti-slip pad 7 can prevent the screw 3 from sliding; a positioning sleeve 8 is fitted on the outside of the screw 3 near the anti-slip pad 7. The positioning sleeve 8 can position the rotation of the screw 3. A positioning component is provided on the outside of the positioning sleeve 8.

[0031] For further details, please refer to Figure 2 and Figure 3 The positioning component includes a paddle 9, which has multiple paddles arranged in a circular array outside the positioning sleeve 8. Positioning pieces 10 are arranged between the paddles 9. The positioning pieces 10 can fix the position of the positioning sleeve 8, thereby restricting the rotation of the screw 3. A positioning ring 11 is fixedly connected to the end of the positioning piece 10 away from the paddle 9. A positioning block 12 is slidably connected to the outside of the positioning ring 11. The positioning block 12 can fix the positioning ring 11, thereby restricting the positioning piece 10. The positioning block 12 is fixedly connected to one side of the support rod 2, making the positioning block 12 more stable on the side of the support rod 2. The output end of the hydraulic rod 5 abuts against a push plate 13. A sliding groove 18 is opened inside the push plate 13. The sliding groove 18 can control the picking clamp 14 to clamp. The picking clamp 14 is slidably connected inside the sliding groove 18.

[0032] For further details, please refer to Figure 1 and Figure 4The slide 18 is inclined, which facilitates the control of the picking clamp 14 for gripping and opening. One end of the picking clamp 14 is rotatably connected to one side of the housing 1. The picking clamp 14 can be opened and closed by rotating on one side of the housing 1. The outer part of the picking clamp 14 is wider away from the housing 1, which can grip fruits or tea leaves. A retrieval port 16 is provided on the outer part of the housing 1 near the support rod 2. The retrieval port 16 facilitates the removal and disassembly of the positioning ring 11. A cover plate 17 is provided on the top of the housing 1 to seal the housing 1. A connecting bolt 15 is rotatably connected to the inside of the push plate 13 near the center. The connecting bolt 15 can fix the push plate 13. The connecting bolt 15 is rotatably connected to the inside of the output end of the hydraulic rod 5. The connecting bolt 15 can connect the push plate 13 and the output end of the hydraulic rod 5.

[0033] In this embodiment, when in use, the hydraulic rod 5 drives the push plate 13 to move, so that the push plate 13 drives the picking clip 14 to open and close outside the housing 1 by relying on the slide groove 18. This allows the picking clip 14 to pick fruits or tea leaves. The push plate 13 is connected to the output end of the hydraulic rod 5 by the connecting bolt 15.

[0034] When different fruits need to be harvested, the hydraulic rod 5 needs to be replaced. At this time, the cover plate 17 can be removed, and the positioning ring 11 can be removed from the positioning block 12 through the retrieval port 16. Then, the screw 3 and nut 6 can be removed from the support rod 2 and rotating block 4 by rotation. Then, the connecting bolt 15 can be removed from the push plate 13. In this way, the hydraulic rod 5 and rotating block 4 can be taken out for replacement.

[0035] When replacing the hydraulic rod 5, pass the output end of the hydraulic rod 5 through the housing 1, then place the rotating block 4 between the support rods 2. Then pass the screw 3 through the support rods 2 and the rotating block 4, and then install the nut 6 on the outside of the screw 3 to fix the rotating block 4. Then install the positioning sleeve 8 on the outside of the screw 3, and then install the positioning ring 11 between the positioning blocks 12. This completes the installation process.

[0036] When the hydraulic rod 5 vibrates, the paddle 9 outside the positioning sleeve 8 is restricted by the positioning piece 10 inside the positioning ring 11. This allows the positioning ring 11 to fix the positioning sleeve 8. Even if vibration occurs, the positioning block 12 can restrict the position of the positioning ring 11 and the positioning piece 10, thereby allowing the positioning piece 10 to restrict the paddle 9 and the positioning sleeve 8. This ensures the stability of the rotating block 4 and the hydraulic rod 5 fixed between the support rod 2.

[0037] It should be noted that this device uses a positioning sleeve 8 to position the screw 3 outside the screw 3. Even if the screw 3 vibrates, the positioning sleeve 8 is restricted by the pawl 9 between the positioning plates 10, and the positioning plates 10 are fixed by the positioning ring 11 and the positioning block 12. In this way, the rotation of the screw 3 can be restricted, avoiding the screw 3 from loosening due to the vibration of the hydraulic rod 5, and improving the stability of the screw 3 inside the support rod 2 and the rotating block 4.

[0038] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
