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.

[0037] See also Figure 1 The first embodiment of the utility model provides a harvesting device 1 for stem crops, including a frame body 10 and a conveying mechanism 11 arranged on the frame body 10, the frame body 10 includes a base 100 and a bracket 101, a push handle 18 is connected to the bracket 101, the conveying mechanism 11 is inclined relative to the base 100, and the height of the end of the conveying mechanism 11 close to the push handle 18 is higher than the other end away from the push handle 18, a limiting plate 12 is arranged at the end of the conveying mechanism 11 away from the push handle 18, a cutting device 13 is also arranged on the side of the conveying mechanism 11 close to the base 100, a collecting device 16 is arranged at a position on the base 100 corresponding to the cutting device 13, and a digging device 15 is also arranged at a position of the base 100 close to the limiting plate 12.

[0038] It can be understood that the harvesting device 1 provided in this embodiment is mainly used for harvesting stem crops such as taro, and taro is used for illustration in this embodiment; the operator uses the push handle 18 to control the forward direction of the harvesting equipment. When the harvesting equipment 1 is in operation, the soil is loosened by the digging device 15, and at the same time, the limiting plate 12 guides the taro stalks to the conveying mechanism 11 for clamping so as to pull them out of the soil and transport them. During the transportation process, the taro passes through the cutting device 13, and the taro stalks are cut by the cutting device 13, and the cut taro falls into the collecting device 16.

[0039] Furthermore, the conveying mechanism 11 includes two transmission devices 110, and a gap 111 is 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 at 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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 outer side is provided with first protruding teeth 1123 at intervals, and the outer sides of the synchronous belts on the two transmission devices 110 are provided opposite to each other.

[0044] 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, which may cause the stems to be unable 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 to tightly bind the taro stems. In addition, since the water content of taro stems is relatively high, directly clamping them tightly with the synchronous belts can easily allow a large amount of water to flow out, causing slipping. By setting the first convex teeth, large-area squeezing of the stems can be avoided.

[0045] The transmission components 112 on the two transmission devices 110 operate synchronously, and the rotation speeds of the pulleys 1120 are equal.

[0046] 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 .

[0047] It can be understood that in order to prevent the synchronous belt 1122 and the pulley 1120 from slipping and causing the phenomenon of speed asynchrony, a second protruding 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 protruding tooth 1124 cooperates with the groove 1121 on the pulley 1120 to avoid slipping.

[0048] 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 .

[0049] 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.

[0050] Furthermore, mutually meshing gears 115 are provided on the gear shafts 1132 adjacent to each other of the two transmission devices 110 .

[0051] 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.

[0052] Furthermore, the limiting plate 12 is arranged on the cross bar 1131 on the transmission device 110 .

[0053] The function of the limiting plate 12 is to guide the stems into the gap 111 between the two transmission devices 110 for 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 smaller, and the distance at the other end is larger, thereby achieving the guiding function.

[0054] Furthermore, the cutting device 13 includes a connecting rod 131 and a cutting knife 132 . Both 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 arranged on the connecting rod 131 .

[0055] The cutting knife 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.

[0056] Specifically, the cutting blade 132 is located in the gap 111 between the two transmission devices 110 .

[0057] 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, 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.

[0058] It can be understood that since the second pulley 134 is provided on the central axis 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, it synchronously drives the central axis 133 and the cutting knife 132 thereon to rotate, thereby realizing the rapid separation of taro and stems.

[0059] Furthermore, the collecting device 16 includes a frame 161 and a roller 162 spaced apart at the bottom of the frame 161 , and the roller 162 is rotatably connected to the frame 161 .

[0060] It is understandable that the taro will carry some soil with it when it is just dug out. After the taro falls and is collected in the collecting device 16, since the entire harvesting device 1 will experience a certain degree of bumps when moving, the taro will collide with the roller 162 during the bumps, thereby shaking off some of the soil, and the shaken-off soil will leak back to the ground through the gaps between the rollers 162.

[0061] Furthermore, the excavating device 15 includes an excavating shovel 151, a support rod 151, a rotating rod 153, a fixed rod 154 and a crank-rocker mechanism 155, the rotating rod 153 and the fixed rod 154 are connected to the support rod, the crank-rocker mechanism 155 includes a crank 1541 connected to the rotating rod 153, a rocker 1542 movably connected to the fixed rod 154, and a connecting rod 1543 connecting the crank 1541 and the rocker 1542, and the excavating shovel 151 is arranged at one end of the connecting rod 1543 close to the rocker 1542.

[0062] It can be understood that by arranging the rocker 1542 on the crank rocker mechanism 155, wherein when the crank 1541 rotates, the digging shovel 151 can rise and fall and adjust the angle of the digging shovel 151, and the rocker 1542 is a follower that performs a reciprocating swinging motion, thereby imitating the role of a person in digging, and the digging device can loosen the soil to a certain extent, thereby making it convenient to use the conveying mechanism to clamp the stems and pull out the taro.

[0063] Specifically, in this embodiment, the rotating rod 153 is connected to the wheel drive shaft through a set of transmission components. When the wheel rotates, the rotating rod 153 is driven by the transmission component to rotate. The transmission component is the same as the transmission component described above, and is also formed by a combination of two pulleys and a synchronous belt.

[0064] Furthermore, a collection trough 17 is provided on the bracket 101 near the end of the conveying mechanism, and the bottom 171 of the collection trough 17 is inclined relative to the horizontal plane. The collection trough 17 is provided with a first opening 172 on the side corresponding to the conveying mechanism 11, and a second opening 173 is provided on the side corresponding to the lowest position of the bottom 171.

[0065] It can be understood that after the taro is cut, the conveying mechanism 11 continues to clamp the stems and transport them from the first opening 172 into the aggregate trough 17. Since the bottom 171 of the aggregate trough 17 is inclined, the stems entering the aggregate trough 17 will slide along the bottom 171 and fall out from the second opening 173. In this embodiment, the second opening 173 is set on the side so that the falling position of the stems will not affect the walking of the operator behind.

[0066] Furthermore, a cleaning device 14 is provided on one side of the conveying mechanism close to the base 100 .

[0067] The cleaning device 14 is arranged 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.

[0068] Specifically, the cleaning device 14 can be a brush, or a water spraying device, etc.

[0069] Compared with the prior art, the harvesting device 1 for stem crops provided by the utility model has the following advantages:

[0070] 1. An embodiment of the utility model provides a harvesting device for stem crops. When the harvesting device is in operation, the soil is loosened by an excavating device, and at the same time, the limiting plate guides the taro stalks to the conveying mechanism for clamping so as to be pulled out of the soil and transported. During the transportation process, the taro passes through the cutting device, and the taro stalks are cut by the cutting device. The cut taro falls into the collecting device, which can achieve excavation before cutting, can retain the integrity of the taro to a certain extent, and can better cut the taro stalks.

[0071] 2. The utility model provides a harvesting device for stem crops. When collecting taro, there is no need to cut the stem first. The whole taro can be directly clamped and pulled out through the clamping and conveying mechanism 11. It is mainly achieved by staggered arrangement on the synchronous belts 1122 on both sides, imitating the way people hold a brush in their hands to write, making the clamping of the stem more stable.

[0072] The above shows and describes the basic principle, main features and advantages of the utility model.
