Description

Technical Field

[0001] This utility model relates to a harvesting device, and in particular to a rotatable swing-type threshing harvesting device. Background Technology

[0002] Nuts typically grow high in trees, and harvesting them manually requires climbing the tree or using tools like bamboo poles to knock the nuts down, which is time-consuming and laborious. Workers may also face danger due to the weight-bearing capacity of tree branches and other uncontrollable factors, and maintaining an upright posture for extended periods can also cause physical injury.

[0003] In some mountainous areas, such as Yunnan, nut plantations are mostly located in mountainous terrain with complex topography, posing safety hazards. Traditional harvesting equipment struggles to maneuver freely, impacting harvesting efficiency and making harvesting a major challenge for growers. Although dwarfing tree planting has been promoted to facilitate harvesting, excessive dwarfing affects fruit yield and sunlight utilization. As a result, many fruit trees remain taller than a person, with some fruits reaching nearly 4 meters in height, requiring the use of tools such as stools and short ladders for harvesting. Chinese utility model patent CN217608409U discloses a vibrating harvesting head for a nut harvester, specifically including: a shell, a transmission mechanism, a control mechanism, and a clamp. The transmission mechanism and control mechanism are both installed within the shell, connected to the control mechanism, and connected to the clamp. However, such harvesting devices generally have fixed angles or limited adjustment ranges, making it difficult to handle nuts at different growth angles and locations. Nuts hidden among branches and leaves, those growing at tricky angles, or those on thorny branches are often difficult to reach precisely, leading to missed harvests or harvesting difficulties. Moreover, the traditional harvesting machines on the market require the entire handheld unit to be flipped and adjusted to change the angle for harvesting at different angles. This is not only inflexible to operate, but also labor-intensive and seriously affects harvesting efficiency. Utility Model Content

The inner rod is adapted to the rod groove.

[0012] In the aforementioned rotatable swing-type sparse picking device, the moving part includes a connecting plate connected to the sparse brush head, the connecting plate is provided with an inclined moving hole, and the first flange bearing of the slider is embedded in the moving hole.

[0017] In the aforementioned rotatable swing-type harvesting device, spring-connected buffer blocks are provided on both sides of the output end of the moving part.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. This utility model features a protruding head at the end of the inner rod, and an annular groove at the connection between the moving part and the inner rod. The protruding head is embedded in the annular groove, and a rod groove is provided on one side of the annular groove. The inner rod is adapted to the rod groove, ensuring uninterrupted power transmission of the inner rod during the rotation and adjustment of the moving part and the brush head. The core innovation of this structure lies in the embedded cooperation between the protruding head and the annular groove, which constructs a 360-degree free rotation mechanism for the "handheld rod-brush head," with uninterrupted power transmission during rotation. This design fundamentally differs from the traditional adjustment method that requires the entire main unit to be flipped, enabling the function of picking at any angle simply by rotating the wrist. The structure of the protruding head embedded in the annular groove ensures that the connection between the moving part and the brush head remains uninterrupted during rotational adjustment. This allows the power from the inner rod to be continuously and stably transmitted to the moving part and the brush head, preventing problems such as jamming or interruption in power transmission due to adjustment movements. This guarantees the continuity and stability of power transmission, ensuring smooth operation of the equipment. Simultaneously, the fitting design of the inner rod and the groove allows for precise alignment during assembly, enhancing the overall structural compactness, reducing wobbling and gaps between components, lowering the risk of malfunctions caused by loosening, improving structural adaptability and reliability, maintaining structural stability during long-term use, and extending the equipment's lifespan. Furthermore, it enhances the convenience and flexibility of adjustment operations. Since power transmission is unaffected by rotational adjustment, users can freely and flexibly adjust the angle and position of the moving part and the brush head according to actual needs without worrying about interfering with the normal operation of the equipment. This meets the usage requirements of different scenarios, simplifies adjustment operations, and improves the user experience.

[0020] 2. The moving part of this utility model includes a connecting plate connected to the brush head. The connecting plate has an inclined moving hole. A first flange bearing of the slider is embedded in the moving hole, and a first flange bearing is sleeved on the second through rod. The slider also includes a moving gap penetrating the middle section of the second through hole. The input end of the moving part includes a fixed rod that penetrates the entire input end of the moving part. A second flange bearing is sleeved on the fixed rod and inside the input end of the moving part. One end of the connecting plate includes a swing arm. One end of the swing arm is sleeved outside the second flange bearing. The swing arm swings within the moving part. The other end of the swing arm is connected to the moving hole, and the moving hole swings within the moving gap. The connecting plate is composed of an inclined moving hole and a swing arm on the fixed rod. The inclined moving hole can expand the swing range of the connecting plate. By limiting the position of the moving hole and the moving gap in the slider, and limiting the position of the fixed rod and the second flange bearing, the movement range of the swing arm and the moving hole within the moving part, i.e., the movement range of the connecting plate, is limited, forming a linkage mechanism of "swing arm swing - moving hole follow". This structure can offset some of the radial or axial impact force through the cooperation between components, reducing swaying and improving the stability of the moving parts during operation; while the design of the flange bearing can reduce the frictional resistance between the components by taking advantage of its characteristics, effectively reducing the jamming and abnormal wear during the swing arm swing and the movement of the moving hole, and significantly extending the service life of the overall structure.

[0021] 3. The output end of the moving part of this utility model is provided with spring-connected buffer blocks on both sides. The buffer blocks are made of rubber. When the brush head swings to its limit position, the buffer blocks can provide timely cushioning and protection for the brush head, preventing the brush head from swinging too fast and being damaged. The connection between the buffer blocks and the springs further weakens the inertia caused by the swing of the brush head, reduces the probability of damage to the brush head, reduces wear, and improves service life.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0030] Example: A rotatable, swing-type harvesting device, configured as follows Figure 1-6As shown, it includes: a linkage mechanism 101, which includes an outer rod 102, one end of which is connected to a handheld part 1. The handheld part 1 drives an inner rod 103 to move axially at high speed. The inner rod 103 is provided inside the outer rod 102, and one end of the inner rod 103 passes through the handheld part 1. A motion part 201 is connected to the end of the inner rod 103 of the linkage mechanism 101. The motion part 201 is used to convert the axial movement of the inner rod 103 into a swinging motion. The motion part 201 includes a housing 2 connected to the outer rod 102. The housing 2 has an inner groove 203 inside, and a slider 204 is provided in the inner groove 203. An annular groove 202 is formed at the end of the slider 204. A first flange bearing 205 is provided at the end of the slider 204. An annular groove 202 is provided at the connection between the moving part 201 and the inner rod 103. Specifically, the annular groove 202 is located at the end of the slider 204, with one end of the groove penetrating the slider 204. A rod groove 2031 is provided on one side of the annular groove 202, with one end penetrating the slider 204. The inner rod 103 is fitted into the rod groove 2031, and a protrusion 1031 is provided at the end of the inner rod 103. The protrusion 1031 is embedded in the annular groove 202, ensuring uninterrupted power transmission to the inner rod 103 during the rotation and adjustment of the moving part 201 and the brush head 301. This structure, through the embedded cooperation of the protrusion 1031 and the annular groove 202, establishes a 360-degree free rotation mechanism for the "handheld rod-brush head," with uninterrupted power transmission during rotation. This design fundamentally differs from the traditional adjustment method that requires the entire main unit to be flipped, enabling the device to be adjusted to any angle for picking simply by rotating the wrist. The structure of the protruding head 1031 embedded in the annular groove 202 ensures that the connection between the moving part 201 and the brush head 301 remains uninterrupted during rotational adjustment. This allows the power of the inner rod 103 to be continuously and stably transmitted to the moving part 201 and the brush head 301, preventing problems such as jamming or interruption in power transmission caused by adjustment movements. This ensures the continuity and stability of power transmission, guaranteeing smooth operation of the equipment. Simultaneously, the matching design of the inner rod 103 and the rod groove 2031 allows for precise alignment during assembly, enhancing the overall structural compactness, reducing wobbling and gaps between components, lowering the risk of malfunctions caused by loosening, improving structural adaptability and reliability, maintaining structural stability during long-term use, and extending the equipment's service life. Furthermore, it enhances the convenience and flexibility of adjustment operations. Since power transmission is unaffected by rotational adjustment, users can freely and flexibly adjust the angle and position of the moving part 201 and the brush head 301 according to actual needs without interfering with the normal operation of the equipment. This meets the usage requirements of different scenarios, simplifies adjustment operations, and improves the user experience.Both sides of the output end of the motion unit 201 are equipped with spring-connected buffer blocks 2012. The buffer blocks 2012 are made of rubber. When the brush head 301 swings to its limit position, the buffer blocks 2012 can provide timely cushioning and protection for the brush head 301, preventing the brush head 301 from swinging too fast and being damaged. The connection between the buffer blocks 2012 and the springs further reduces the inertia caused by the swing of the brush head 301, reducing the probability of damage to the brush head 301, reducing wear, and improving service life. The brush head 301 is connected to the motion unit 201, which drives the brush head 301 to swing left and right.

[0031] like Figure 2-6As shown: The moving part 201 includes a connecting plate 206 connected to the brush head 301. The connecting plate 206 has an inclined moving hole 207. The first flange bearing 205 of the slider 204 is embedded in the moving hole 207. The slider 204 includes a first through hole 2041, through which a first through rod 2043 passes. The slider 204 also includes a second through hole 2042, through which a second through rod 2044 passes. First bearings 2045 are fitted at both ends of the first through rod 2043 and the second through rod 2044 and on the outside of the slider 204. The second through rod 2044 is fitted with a first flange bearing 205. The slider 204 includes a moving gap 208 that passes through the middle section of the second through hole 2042. The input end of the motion section 201 includes a fixed rod 2061 that runs through the entire input end of the motion section 201. A second flange bearing 2062 is fitted on the fixed rod 2061 and inside the input end of the motion section 201. One end of the connecting plate 206 includes a swing arm 2063, one end of which is fitted outside the second flange bearing 2062. The swing arm 2063 swings within the motion section 201, and the other end of the swing arm 2063 is connected to a motion hole 207, which swings within a motion gap 208. A first linear bearing 104 is fitted on the inner rod 103 at the input end of the motion section 201. A bearing sleeve 105 is fitted over the first linear bearing 104 and fixed to the inner end of the outer rod 102. A limiting plate 209 is provided at the end of the bearing sleeve 105, and an inner groove 203 is connected to the other side of the limiting plate 209. A fixed sleeve 210 is provided inside the input end of the motion part 201. The outer rod 102 passes through the fixed sleeve 210, and the fixed rod 2061 passes through the fixed sleeve 210. One end of the swing arm 2063 and the second flange bearing 2062 are both fixed inside the fixed sleeve 210. The connecting plate 206 consists of an inclined motion hole 207 and a swing arm 2063 on the fixed rod 2061. The inclined motion hole 207 can expand the swing range of the connecting plate 206. Through the positional restriction of the motion hole 207 and the motion gap 208 in the slider 204, and the positional restriction of the fixed rod 2061 and the second flange bearing 2062, the movement range of the swing arm 2063 and the motion hole 207 in the motion part 201, that is, the movement range of the connecting plate 206, is limited, forming a linkage mechanism of "swing arm 2063 swinging - motion hole 207 following". This structure can offset some of the radial or axial impact force through the cooperation between components, reduce shaking, and improve the stability of the moving part 201 during operation; while the design of the flange bearing can reduce the frictional resistance between the components by taking advantage of its characteristics, effectively reducing the swing of the swing arm 2063 and the jamming and abnormal wear during the movement of the moving hole 207, and significantly extending the service life of the overall structure.

[0032] Working principle: When in use, the user holds the holding part 1, and the device is in its initial state with the brush head 301 stationary. The user moves the device close to the nuts, passing the brush head 301 through the gaps in the branches to be harvested. The switch is turned on, the motor rotates, which in turn drives the linkage mechanism 101 to slide, thereby driving the inner rod 103 to slide. As the inner rod 103 slides, the protrusion 1031 at the end of the inner rod 103 engages with the annular groove 202 in the slider 204, thus driving the slider 204 to slide. As the slider 204 slides, the motion hole 207 in the linkage connecting plate 206 swings, thereby driving the connecting plate 206 to swing. The swinging of the connecting plate 206, along with the fixed rod 2061, the second flange bearing 2062, and the swing arm... Arm 2063 limits the swing range of connecting plate 206, thereby causing brush head 301 to swing within the range of motion; the swing of brush head 301 causes fruit branches to shake, causing nuts to detach from the branches and fall; after the nuts fall, the user moves the device to remove brush head 301 from the gaps between fruit branches, completing one nut harvest; the user rotates the device, that is, through the cooperation structure of protrusion 1031 and annular groove 202, only needs to rotate the wrist on the hand handle to flexibly allow the hand handle and brush head 301 to achieve 360-degree unobstructed rotation, without having to rotate the hand main unit, and passes the rotated brush head 301 through the gaps between other fruit branches to be harvested, repeating the movement, thereby harvesting nuts from different angles and different fruit branches.
