[0002] Taro is an important aquatic vegetable in my country. It is soft and sticky, rich in nutritional value, and has high economic benefits. It is widely planted in my country. The labor intensity of taro harvesting is high, the working environment is complex, and there are many harvesting procedures, which to a certain extent restricts the industrialization and large-scale development of taro.
[0003] my country's taro cultivation technology is relatively advanced, but the level of taro harvesting mechanization technology is relatively low. For a long time, it has mainly relied on manual harvesting and semi-mechanized harvesting, among which manual harvesting relies heavily on human and animal power, increasing labor costs.
[0004] The current mechanized automatic harvesting device for taro uses a clamping mechanism to clamp the taro stems and cut them first, and then shovel the taro out of the ground and pile them on the ground for workers to collect. Manual harvesting is still required, and since the growth depth of taro is uncertain, it is easy to cause stems to remain on some taro after cutting. Most of the current conveying mechanisms rely on a pair of synchronous conveyor belts for clamping, which can easily cause the stems to slip in the vertical direction and fail to clamp.

[0012] Preferably, a cutting device is further provided between the two transmission devices, the cutting device comprising a connecting rod and a cutting knife, the two ends of the connecting rod are respectively connected to the cross bars of the two transmission devices, and the cutting knife is provided on the connecting rod.

[0014] In order to solve the above technical problems, the utility model provides a technical solution, a harvesting device, comprising a frame body and a cross-type clamping and conveying mechanism for stem crops as described above, which is installed on the frame body.
[0015] Compared with the prior art, the cross-type clamping and conveying mechanism and harvesting equipment for stem crops provided by the utility model have the following advantages:
[0016] 1. The embodiment of the utility model provides a cross-type clamping and pulling conveying mechanism for stem crops, which is used for clamping and transporting a whole taro. When collecting taro, there is no need to cut the stem first, and the whole taro can be directly clamped and pulled out by the clamping and conveying mechanism. It is mainly staggered on the synchronous belts on both sides to imitate the way people hold a brush in their hands to write, so that the clamping of the stem is more stable. In addition, since the water content of the taro stem is relatively high, it is easy for a large amount of water to flow out if it is tightly clamped by the synchronous belt, resulting in slipping. The first convex teeth can avoid large-area squeezing of the stem.
[0017] 2. An embodiment of the utility model provides a cross-type clamping and conveying mechanism for stem crops. A first convex tooth is arranged on a synchronous belt. Due to the staggered arrangement of the synchronous belt, the gaps at some positions are smaller, and the stems may not be able to enter the gaps for transportation. Therefore, the first convex tooth can be used to force the stems into the gaps when the synchronous belt moves, and the first convex teeth on both sides of the synchronous belt cooperate with each other to tightly bind the taro stems.
[0018] 3. The embodiment of the utility model provides a cross-type clamping and conveying mechanism for stem crops, which also includes a cleaning device, through which most of the dirt on the taro can be cleaned during the transportation of the taro. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0036] Please refer to Figures 1 to 3. The first embodiment of the utility model provides a cross-type clamping and conveying mechanism 11 for stem crops, including two transmission devices 110, with a gap 111 left between the two transmission devices 110, the transmission device 110 includes a frame 113 and at least one group of transmission components 112 fixed on the frame 113, the transmission component 112 includes two pulleys 1120 respectively fixed to the two ends of the frame 113, and a synchronous belt 1122 sleeved on the two pulleys 1120; at least one transmission device 110 is provided with two groups of transmission components 112, and the synchronous belts 1122 of the two transmission devices 110 are staggered at the gap 111.
[0037] The stalk crops may be crops with stalks such as taro, etc. In this embodiment, taro is taken as an example for description.
[0038] It can also be understood that the entire conveying mechanism 11 includes at least three groups of transmission components 112 for clamping the stems for transportation.
[0039] The three groups of transmission components 112 are staggered and located at different heights, so that more parts of the stem can be clamped more firmly, imitating the way people hold a brush in their hands to write, making the stem clamped more firmly; specifically, in this embodiment, three groups of transmission components 112 are respectively arranged on the two transmission components 112.
[0040] In addition, since multiple sets of transmission components 112 are provided, the width of the synchronous belt 1122 is not specifically limited in this embodiment.
[0041] Furthermore, the side of the synchronous belt 1122 contacting the pulley 1120 is defined as the inner side, and the other side is defined as the outer side. The first protruding teeth 1123 are arranged at intervals on the outer side, and the outer sides of the synchronous belts 1122 on the two transmission devices 110 are arranged opposite to each other.
[0042] It can be understood that the two transmission devices 110 cooperate with each other to achieve the function of clamping and transporting. Specifically, a gap 111 is left between the synchronous belts 1122 of the two transmission devices 110. Due to the staggered arrangement of the synchronous belts 1122, the gap 111 at some positions is smaller, so that the stems may not be able to enter the gap 111 for transportation. Therefore, the first convex teeth 1123 can be used to force the stems into the gap when the synchronous belt 1122 moves, and the first convex teeth 1123 on the synchronous belts 1122 on both sides cooperate with each other.
[0043] The taro stems are tightly bound. In addition, since the water content of the taro stems is relatively high, directly clamping them with the synchronous belt 1122 will easily cause a large amount of water to flow out, resulting in slippage. The first protruding teeth 1123 can avoid squeezing the stems over a large area.
[0044] The transmission components 112 on the two transmission devices 110 operate synchronously, and the rotation speeds of the pulleys 1120 are equal.
[0045] Furthermore, grooves 1121 are arranged at intervals on the side of the pulley 1120 contacting the synchronous belt 1122 , and second protruding teeth 1124 are arranged on the inner side of the synchronous belt 1122 corresponding to the grooves 1121 .
[0046] It can be understood that in order to prevent the synchronous belt 1122 and the pulley 1120 from slipping and causing the speed to be asynchronous, a second convex tooth 1124 is provided on the inner side of the synchronous belt 1122. Therefore, the synchronous belt 1122 can also be regarded as a closed rack here. The second convex tooth 1124 cooperates with the groove 1121 on the pulley 1120 to avoid slipping.
[0047] Furthermore, the frame 113 includes two gear shafts 1132 and a cross bar 1131 connecting the two gear shafts 1132 , the pulley 1120 is sleeved on the gear shafts 1132 , wherein the gear shafts 1132 are movably connected to the cross bar 1131 , and one of the gear shafts 1132 is connected to the driving device 114 .
[0048] It can be understood that the pulley 1120 is fixed on the gear shaft 1132 and rotates along with the rotation of the gear shaft 1132; the driving device 114 can be a motor and the like.
[0049] Furthermore, mutually meshing gears 115 are provided on the gear shafts 1132 of the two transmission devices 110 that are close to each other.
[0050] Preferably, the gear 115 is preferentially arranged on the gear shaft 1132 connected to the driving device 114, and the gear shaft 1132 on the other transmission device 110 is also provided with a corresponding meshing gear 115, so that only one driving motor is required to realize the synchronous operation of the two transmission devices 110.
[0051] Furthermore, a limiting plate 12 is provided at one end of the crossbar 1131 on the two transmission devices 110 .
[0052] The function of the limiting plate 12 is to guide the stems into the gap 111 between the two transmission devices 110 for easy clamping and transportation. The specific structure of the limiting plate 12 is not limited. In this embodiment, the two limiting plates 12 cooperate with each other, and the limiting plates 12 are inclined relative to the channel. The distance between the two limiting plates 12 at one end close to the channel is small, and the distance at the other end is large, so as to achieve the guiding function.
[0053] Please refer to FIG. 4 , further, a cleaning device 14 is provided on the cross bar 1131.
[0054] The cleaning device 14 is disposed at the bottom of the transmission device 110 and close to the gap 111 between the two transmission devices 110. During transportation, the taro will first pass through the cleaning device 14, so that most of the dirt on the taro can be cleaned.
[0055] Specifically, the cleaning device 14 can be a brush, or a water spraying device, etc.
[0056] 4 , further, a cutting device 13 is provided between the two transmission devices 110 , the cutting device 13 comprises a connecting rod 131 and a cutting knife 132 , the two ends of the connecting rod 131 are respectively connected to the cross bars 1131 of the two transmission devices 110 , and the cutting knife 132 is provided on the connecting rod 131 .
[0057] The cutting tool 132 is a blade, and the cutting device 13 is arranged after the cleaning device 14. During transportation, the taro first contacts the cleaning device 14 and then contacts the cutting device 13 for cutting. The cutting device 13 directly cuts the taro and then collects it.
[0058] Specifically, the cutting blade 132 is located in the gap 111 between the two transmission devices 110 .
[0059] Furthermore, a central axis 133 is movably provided on the connecting rod 131, the central axis 133 passes through the connecting rod 131, and the cutting knife 132 is connected to one end of the central axis 133, and a second pulley 134 is provided at the other end of the central axis 133, and a third pulley 135 is provided on one of the gear shafts 1132, and a second synchronous belt 136 is sleeved on the second pulley 134 and the third pulley 135.
[0060] It can be understood that since the second pulley 134 is provided on the central shaft 133 and is connected to the third pulley 135 provided on the gear shaft 1132 through the second synchronous belt 136, when the gear shaft 1132 rotates, the central shaft 133 and the cutting knife 132 thereon are synchronously driven to rotate, thereby realizing the rapid separation of taro and stems.
[0061] Specifically, in this embodiment, the cleaning device 14 is a brush, and the cleaning device 14 is movably disposed on the crossbar 1131 . The cleaning device 14 can also be rotated by disposing a transmission assembly 112 .
[0062] Please refer to FIG. 5 . The second embodiment of the present utility model further provides a harvesting device, which is characterized by comprising a frame body 10 and a cross-type clamping and conveying mechanism 11 for stem crops as described in the first embodiment and installed on the frame body 10 .
[0063] The harvesting device has the same beneficial effects as the above-mentioned conveying mechanism 11, which will not be described in detail here.
[0064] Compared with the prior art, the cross-type clamping and conveying mechanism 11 and the harvesting device 1 for stem crops provided by the present invention have the following advantages:
[0065] 1. The utility model provides a cross-type clamping and pulling conveying mechanism 11 for stem crops, which is used to clamp and transport a whole taro. When collecting taro, there is no need to cut the stem first. The whole taro can be directly clamped and pulled out by the clamping and conveying mechanism 11. It is mainly staggered on the synchronous belts 1122 on both sides to imitate the way people hold a brush to write, so that the clamping of the stem is more stable. In addition, since the water content of the taro stem is relatively high, it is easy for a large amount of water to flow out if it is directly clamped tightly with a synchronous belt, resulting in slipping. The first convex teeth can avoid squeezing the stem over a large area.
[0066] 2. The embodiment of the utility model provides a cross-type clamping and conveying mechanism 11 for stem crops. By setting the first convex teeth 1123 on the synchronous belt 1122, the gaps 111 at some positions are smaller due to the staggered arrangement of the synchronous belt 1122, so that the stems may not be able to enter the gaps 111 for transportation. Therefore, the first convex teeth 1123 can be used to force the stems into the gaps when the synchronous belt 1122 moves, and the first convex teeth 1123 on the synchronous belts 1122 on both sides cooperate with each other to tightly bind the taro stems.
[0067] 3. The embodiment of the utility model provides a cross-type clamping and conveying mechanism 11 for stem crops, which also includes a cleaning device 14, through which most of the dirt on the taro can be cleaned during the transportation of the taro.
[0068] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
