Technical Field

[0001] The utility model relates to the technical field of taro harvesting, in particular to a combined turning and harvesting taro harvester. Background Art

[0002] At present, the harvesting of taro still adopts the traditional manual operation method, which seriously restricts the development of the taro planting industry and has low production efficiency. Designing and developing a combined turning and harvesting taro harvester that integrates excavation, harvesting, and screening can efficiently complete the harvesting work of taro, reduce the economic cost of manual harvesting, be suitable for the planting environment of taro in China, and make up for the shortcomings of the traditional manual harvesting method with low work efficiency and poor quality. While harvesting taro, the multi-link mechanism is optimized and the harvesting process is standardized. Functions such as separating the soil covering the fruits and screening with a sieve are designed, which improves the screening and harvesting efficiency and quality of taro, and further improves the excellent rate of the fruits.

[0003] However, in the process of using the existing combined turning and harvesting taro harvester, although the primary screening and fine screening of taro are realized through the design of a double-layer sieve to ensure a certain purity, in the process of using the existing combined turning and harvesting taro harvester, due to the double-layer design of the sieve, when the taro after screening needs to be taken off the sieve, the distance between the bottom sieve and the top sieve is small, and at the same time, the sieve cannot be removed from the connecting frame, resulting in personnel reaching their hands between the bottom sieve and the top sieve, making it inconvenient for personnel to take the taro. Summary of the Utility Model

[0035] The present utility model will be further described below with reference to the drawings:

[0036] A turnip harvesting machine with an integrated turning and harvesting function proposed in this embodiment, as Figure 1As shown in the figure, a second connection hole 102 is provided on the left side of the connecting frame 1 for supporting the wheel seat of the support wheel, and a second connection hole 102 is provided on the right side of the connecting frame 1 for connecting the traveling wheel shaft of the integrated turning and harvesting taro harvester. Auxiliary structures 2 are provided on both sides of the connecting frame 1 to facilitate the recovery of the taro on the top of the screen after harvesting by personnel.

[0037] As Figure 1 and Figure 2 shown, the auxiliary structure 2 includes a connection component 201, a limit component 202, a guiding component 203, and a wire mesh frame 204. The connection component 201 is used to connect the wire mesh frame 204 to the connecting frame 1. The guiding component 203 ensures that the wire mesh frame 204 can slide stably. The limit component 202 is used to limit the movement of the wire mesh frame 204.

[0038] As Figure 1 , Figure 2 and Figure 3 shown, the connection component 201 is composed of a first connecting rod 2011, a second connecting rod 2013, and a U-shaped connecting rod 2012. The number of the first connecting rods 2011 is four. The middle parts of the first connecting rods 2011 are all hinged to the connecting frame 1. One end of each two adjacent first connecting rods 2011 is hinged to the U-shaped connecting rod 2012. The top of the first connecting rod 2011 adjacent to the first connection hole 101 is hinged to the second connecting rod 2013. The other side of the second connecting rod 2013 is hinged to the traveling wheel of the integrated turning and harvesting taro harvester. During the operation of the integrated turning and harvesting taro harvester, with the rotation of the traveling wheel, the second connecting rod 2013 is driven to rotate. The second connecting rod 2013 drives the first connecting rod 2011 adjacent to the first connection hole 101 to rotate. At the same time, the first connecting rod 2011 drives the U-shaped connecting rod 2012 to rotate. The U-shaped connecting rod 2012 makes the wire mesh frame 204 swing through the guiding component 203. The taro is screened through the screen arranged inside the wire mesh frame 204.

[0039] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the guiding component 203 is composed of a guiding rod 2031 and a guiding block 2032. The end of the guiding rod 2031 is fixedly connected to the U-shaped connecting rod 2012. A sliding groove 2033 is arranged in the middle of the guiding rod 2031. The shape of the sliding groove 2033 is the same as that of the guiding block 2032. The guiding block 2032 is matched with the sliding groove 2033. The guiding block 2032 can slide inside the sliding groove 2033. The ends of the two guiding blocks 2032 are both rotatably connected to the wire mesh frame 204. While the wire mesh frame 204 can drive the two guiding blocks 2032 to slide along the sliding groove 2033, the wire mesh frame 204 can rotate along the guiding block 2032. An insertion hole 2034 is arranged on the side end of the guiding rod 2031 adjacent to the second connection hole 102 for connecting the limit component 202.

[0040] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 shown, the limit component 202 includes an L-shaped rod 2021, a plug rod 2022, a spring 2023 and a square block 2024. The end of the L-shaped rod 2021 is fixedly connected to the grid frame 204. A round hole 2025 is provided on one side of the L-shaped rod 2021. The round hole 2025 is matched with the plug rod 2022. The plug rod 2022 can slide inside the round hole 2025. The middle part of the plug rod 2022 is fixedly connected to the square block 2024. The end of the square block 2024 is attached to the L-shaped rod 2021. The square block 2024 slides along the L-shaped rod 2021 to prevent the plug rod 2022 from deflecting. The two ends of the spring 2023 are respectively fixedly connected to the L-shaped rod 2021 and the square block 2024. The elastic force of the spring 2023 is used to limit the plug rod 2022 to prevent the plug rod 2022 from moving around. The end of the plug rod 2022 is matched with the jack 2034. Through the cooperation between the plug rod 2022 and the jack 2034, the grid frame 204 is restricted and supported at the same time.

[0041] Working principle:

[0042] Connect the connecting frame 1 to the traveling wheel axle of the integrated turning and harvesting taro harvester and the wheel seat of the supporting wheel through the first connection hole 101 and the second connection hole 102. Then connect the second connecting rod 2013 to the traveling wheel, so that the integrated turning and harvesting taro harvester drops the harvested taro onto the screen inside the grid frame 204. As the second connecting rod 2013 rotates following the traveling wheel, the screens on both sides of the grid frame shake, thereby screening the taro on the top of the screen;

[0043] When there is a lot of taro on the screen and it needs to be removed from the screen, the operator pulls the plug rod 2022 at the top. The plug rod 2022 drives the square block 2024 to move. The square block 2024 drives the spring 2023 to compress. The plug rod 2022 is separated from the jack 2034. At the same time, the operator pulls the grid frame 204 at the top. The grid frame 204 at the top drives the guide block 2032 to slide along the chute 2033 of the guide rod 2031, so that the grid frame 204 moves away from directly above the connecting frame 1. Then the operator turns the grid frame 204 towards the ground, so that the taro on the screen slides off the grid frame 204. Then the grid frame 204 at the top is reset. Similarly, the bottom grid frame 204 is pulled out so that the taro on its top slides off and then is reset.
