[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0034] As mentioned in the background technology, although fixed-point harvesting robots can be introduced to automate large-scale fruit harvesting operations, positioning and determination are required before harvesting, which increases harvesting time and thus affects harvesting efficiency.
[0035] Please refer to Figure 1 and Figure 2 The transmission mechanism 100 for a fruit harvester and the fruit harvester provided in the embodiments of this utility model can solve the above problems, and will be described in detail below.
[0036] The transmission mechanism 100 for the fruit harvester includes a transmission chain 110, a transmission sprocket 120, multiple support shafts 130, and multiple harvesting hoppers 140.
[0037] The transmission chain 110 is wound around and cooperates with the transmission sprocket 120, the support shaft 130 passes through the transmission chain 110, and multiple harvesting hoppers 140 are rotatably connected to the support shaft 130. The openings of the multiple harvesting hoppers 140 are aligned with the transmission direction of the transmission chain 110.
[0038] During the harvesting operation, the transmission chain 110 moves in conjunction with the transmission sprocket 120, which in turn drives the harvesting hopper 140 to move. When the harvesting hopper 140 comes into contact with the fruit, it moves and pulls the fruit away from the tree, thereby achieving rapid harvesting of the fruit and improving harvesting efficiency.
[0039] Especially in grape harvesting, because most grape bunches on a trellis are distributed with a certain spacing but also a certain pattern, using a fixed-point harvesting robot would require sequential harvesting and positioning, which could easily affect harvesting efficiency. By using the fruit harvester of this invention, most grape bunches with similar distribution patterns can be harvested uniformly, while the small number of grape bunches with different distribution patterns can be harvested separately, thus fully ensuring harvesting efficiency.
[0040] Please refer to Figures 1-3 The transmission chain 110 includes multiple inner links 111, multiple outer links 112, and multiple pins 113. The multiple inner links 111 and multiple outer links 112 are arranged alternately in sequence. Adjacent inner links 111 and outer links 112 are connected by pins 113. Multiple support shafts 130 are connected to the multiple outer links 112 and / or inner links 111.
[0041] Specifically, the outer link 112 can have a square hole 114 for accommodating the support shaft 130; alternatively, the inner link 111 can have an elongated hole 115 for accommodating the support shaft 130. By utilizing the special shapes of the square hole 114 or the elongated hole 115 to accommodate the support shaft 130, the relative positional stability of the support shaft 130 can be improved, preventing the support shaft 130 from easily changing position relative to the inner link 111 or the outer link 112.
[0042] In this embodiment, the end of the support shaft 130 is square and is used to accommodate the square hole 114; of course, in other embodiments of this utility model, the end of the support shaft 130 can also be elongated and used to accommodate the elongated hole 115.
[0043] Furthermore, two fixing holes can be formed on each side of the square hole 114 or the elongated hole 115. The fixing holes can be circular, fan-shaped or other irregular shapes, and there is no limitation on their specific shapes.
[0044] It is worth noting that, to improve the overall durability of the transmission chain 110, both the outer link 112 and the inner link 111 are made of austenitic stainless steel. Through cold work hardening, the surface hardness reaches HRC39-44, which is twice that of ordinary stainless steel, and the corresponding strength and fatigue resistance are also improved. The pin 113, sleeve, and rollers are made of martensitic stainless steel, and the hardness can reach HRC57-62 through heat treatment, which not only has good corrosion resistance but also good wear resistance. By limiting the materials of the components, it can be ensured that the transmission chain 110 has good corrosion resistance and good wear resistance.
[0045] In this embodiment, there are two sets of transmission chains 110, and the two ends of multiple support shafts 130 are respectively connected to the two sets of transmission chains 110, and multiple harvesting hoppers 140 are located between the two sets of transmission chains 110.
[0046] Of course, in other embodiments of this utility model, the number of transmission chains 110 can be one or three sets, and the support shaft 130 can be simultaneously threaded on one or three sets of transmission chains 110. While the harvesting hopper 140 is rotatably connected to the support shaft 130, it needs to avoid the threading position of the support shaft 130 to prevent interference between the harvesting hopper 140 and the transmission chain 110.
[0047] Please refer to Figure 1 and Figure 2 The inner cavity of the harvesting hopper 140 is formed with a first partition 141, which can separate the fruit harvested by the harvesting hopper 140 from the fruit tree. Specifically, the number of first partitions 141 can be at least two, and the at least two first partitions 141 are used to evenly divide the inner cavity of the harvesting hopper 140 into at least three sub-cavities 142.
[0048] In this embodiment, there are two first partitions 141. The distance between the two first partitions 141 and the distance between them and the two side walls of the harvesting hopper 140 are equal, so that the inner cavity of the harvesting hopper 140 can be divided into four sub-cavities 142.
[0049] Of course, in other embodiments of this utility model, the number of first partitions 141 can be one, three, five, etc., and the number of sub-cavities 142 formed can be two, four, six, etc. The specific number of first partitions 141 and sub-cavities 142 is not limited.
[0050] Please refer to Figure 1 and Figure 2 To prevent the fruit from being squeezed on the back side of the harvesting hopper 140, a second partition 143 can be formed on the back side of the harvesting hopper 140.
[0051] Meanwhile, in order to avoid the second partition 143 affecting the mass distribution of the harvesting hopper 140 and to prevent the harvesting hopper 140 from rotating excessively during operation and causing the opening to face upwards, the bottom end of the second partition 143 can be used to abut against the support shaft 130, thereby limiting the second partition 143 by the support shaft 130, and preventing the harvesting hopper 140 from rotating excessively and having a negative impact on the harvesting operation.
[0052] In this embodiment, there is one second partition 143, which is located in the middle of the back side of the harvester hopper 140. Of course, in other embodiments of this utility model, the number of second partitions 143 may be two or three, and there is no limitation on their specific location.
[0053] Please refer to Figure 1 and Figure 2 In order to facilitate further separation of the harvested fruit, the transmission mechanism 100 for the fruit harvester may also include a separation partition 150. The separation partition 150 has a plurality of separation holes 151 formed on it. The separation partition 150 is connected to the support shaft 130 and is located between two adjacent harvesting hoppers 140.
[0054] As the separator moves with the chain, it will inevitably generate slight vibrations. Combined with the squeezing action of the harvesting hopper 140 on the fruit, the individual fruits can be separated from each other and fall downwards through the separation hole 151 for easy collection.
[0055] It should be noted that when the harvesting hopper 140 on the upper chain is performing harvesting operations, the harvesting hopper 140 on the lower chain is in an idle state. However, under the influence of its own gravity, the harvesting hopper 140 will be in a suspended state and will not obstruct the fruit falling from the upper side.
[0056] An embodiment of this utility model also provides a fruit harvester, including a transmission mechanism 100 for the fruit harvester. The fruit harvester also includes a drive mechanism and a collection mechanism. The drive mechanism is used to connect to the transmission sprocket 120 and provide a rotational power source for the transmission sprocket 120. The collection mechanism is located on the lower side of the transmission mechanism 100 for the fruit harvester and is used to collect the fallen fruit in a unified manner.
[0057] In summary, the transmission mechanism 100 for a fruit harvester and the fruit harvester provided by the embodiments of this utility model have at least the following advantages:
[0058] (1) It is transmitted and moved by the transmission chain 110 in cooperation with the transmission sprocket 120, and synchronously drives the harvesting hopper 140 to move. When the harvesting hopper 140 comes into contact with the fruit, it will move and drive the fruit away from the fruit tree, thereby realizing the rapid harvesting operation of the fruit and improving the harvesting efficiency.
[0059] (2) By limiting the material of the components of the transmission chain 110, it can ensure that the transmission chain 110 has good corrosion resistance and good wear resistance, thereby improving the overall operational stability of the fruit harvester.
[0060] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
