[0046] See also Figures 1 to 5 , this embodiment is a taro harvester, comprising:

[0047] A vehicle body 1, the front end of which is provided with a digging shovel 11;

[0048] The knife sharpening drum mechanism comprises a drum 21, the drum 21 is located in front of the shovel 11, the width of the drum 21 is adapted to the width of the shovel 11, a plurality of knife sharpenings 22 are arranged in an array on the surface of the drum 21, the knife sharpenings 22 comprise an extension portion 221 and a hook portion 222, one end of the extension portion 221 is connected to the surface of the drum 21, and the other end is connected to the hook portion 222, the hook portion 222 is twisted from the extension portion 221 to one side,

[0049] A conveying mechanism, the conveying mechanism is obliquely connected to the rear end of the shovel 11;

[0050] A vibration mechanism is located at the rear end of the transmission mechanism.

[0051] When the vehicle body 1 is moving forward, the knife-grinding roller mechanism rolls to cut the taro vines on the ground, so as to prevent the long vines from winding around the vehicle body 1 and causing difficulty in the movement of the vehicle body 1. In some embodiments, the lowest point of the knife 22 is not lower than the ground, and the knife 22 only cuts the taro vines. In some embodiments, the lowest point of the knife 22 is a certain distance (2-5 cm) below the ground, and the knife-grinding roller mechanism rolls to cut the vines while loosening the surface soil of the ground appropriately, so as to facilitate the shovel 11 to dig up the taro underground.

[0052] The following will specifically describe an embodiment in which the lowest point of the knife 22 is below the ground by a certain distance. The drum 21 of the knife-grinding drum mechanism is suspended above the ground. After the knife 22 on the drum 21 rolls forward, the taro vines in front of the vehicle body 1 are cut. At least part of the knife 22 on the drum 21 will turn over the ground during the rolling process. As the drum 21 rolls, the knife 22 drives the cut vines into the rear conveying mechanism to prevent the cut vines from continuing to entangle the vehicle body 1.

[0053] The extension portion 221 of the sharpener is a knife body structure extending vertically to the surface of the roller 21 and outward from the roller 21. On the side of the forward direction of the roller 21, one end surface of the sharpener 22 facing the forward direction is set as a blade. In some embodiments, blades are set on both sides of the extension portion 221 of the sharpener.

[0054] The hook portion is twisted from the extension portion 221 to one side of the extension portion 221, and the twisted hook portion 222 forms a spoon-shaped structure in the width direction of the roller 21. During the movement of the roller 21, the hook portion 222 of the sharpener 22 turns over the soil on the surface in a spoon-shaped structure, thereby reducing the resistance of the shovel 11 during the pushing process. One end surface of the hook portion 222 of the sharpener 22 facing the forward direction is set as a blade portion. In some embodiments, blade portions are set on both sides of the hook portion 222 of the sharpener 22.

[0055] The taro harvester utilizes multiple sharpeners 22 on the drum 21 to perform multi-stage segmentation on the taro vines on the ground during its rotation and forward movement, thereby preventing the vines from being entangled on the vehicle body 1. The hook portion 222 can also dig up the soil surface, reduce the digging resistance of the shovel 11, and improve the efficiency of taro harvesting.

[0056] In some embodiments, the sharpeners 22 are arranged in rows along the width direction of the drum 21. When the taro harvester is moving, the width of the area that can be processed corresponds to the width of the drum 21. After the sharpeners 22 are arranged in rows along the width direction of the drum 21, the taro vines can be cut into multiple sections and the soil on the surface can be turned over in multiple places during the movement of the vehicle body 1 in the width direction of the drum 21, which increases the cutting area and the turning over area. The efficiency of vine cutting and soil turning over will be effectively improved. The arrangement can also be adjusted according to specific needs. For example, the spacing and number of sharpeners 22 can be determined according to the size and density of the taro to achieve the best harvesting effect.

[0057] In some embodiments, the sharpeners 22 of two adjacent rows are arranged in a staggered manner. This staggered arrangement can increase the coverage of the sharpeners 22, ensuring that the taro vines are fully cut. The soil surface is turned over in a staggered point shape, which destroys the stress on the soil surface and reduces the travel resistance of the shovel 11. After the sharpeners 22 in the front row cut the vines, the vines are moved backward to the sharpeners 22 in the rear row under the action of their hooks 222, and the sharpeners 22 in the rear row further cut them.

[0058] In some embodiments, the front end of the shovel 11 is a flared structure. The design of the flared structure can make the front end of the shovel 11 have a larger opening area, thereby increasing the chance of taro entering the shovel 11. When the taro is contacted by the shovel 11, the flared structure can effectively guide the taro into the working area of ​​the harvester, reducing the possibility of the taro slipping or being missed. Designing the front end of the shovel 11 as a flared structure can improve the harvesting efficiency and quality of the taro harvester. This structure can increase the chance of taro entering the shovel 11, reduce resistance, and reduce damage and breakage of the taro.

[0059] In some embodiments, the width of the drum 21 is adapted to the width of the shovel 11. The width direction of the drum 21 refers to the direction of the central axis of the drum 21. The width direction of the shovel 11 is consistent with the width direction of the drum 21, and the two maintain an adapted width value. The taro harvester moves in a straight line, and the vines and the soil after being cut by the sharpening drum mechanism will directly enter the shovel 11 during the movement. If the width of the drum 21 is not adapted to the width of the shovel 11, it may cause the problem of missing taro during the harvesting process. This will reduce the efficiency and harvesting quality of the harvester and affect the collection and subsequent processing of taro. Therefore, adapting the width of the drum 21 to the width of the shovel 11 is one of the important factors to ensure the normal operation and efficient harvesting of the taro harvester. This can ensure that the taro is fully cut and collected during the harvesting process, and improve the harvesting efficiency and quality.

[0060] In some embodiments, the vibration mechanism includes a screen 31 and an elastic structure 32 located below the screen 31, and the elastic structure 32 is connected to the vehicle body 1. The screen 31 is a key part of the vibration mechanism, and it is usually made of a wire mesh or other materials suitable for screening operations. When the taro passes through the screen 31, soil blocks or impurities will pass through the pores of the screen 31, while the taro will be blocked and collected by the screen 31. In order to increase the screening effect, the elastic structure 32 is placed below the screen 31. This elastic structure 32 is generally made of a spring and has a certain flexibility and elasticity. When the machine is working, the elastic structure 32 will vibrate and vibrate and screen the taro on the screen 31. The elastic structure 32 is connected to the vehicle body 1 so that the entire vibration mechanism can work stably. The vehicle body 1 is usually made of a solid metal material that can withstand the force caused by vibration and vibration while maintaining the stability of the machine. The screening efficiency and quality of taro can be improved by vibration screening.

[0061] In some embodiments, the conveying mechanism includes a conveyor belt 41, on which a plurality of baffles 42 are arranged in an array, and the extending direction of the baffles 42 is the same as the width direction of the drum 21. On the conveyor belt 41, a plurality of baffles 42 are provided, and the baffles can be arranged perpendicular to the surface of the conveyor belt 41. These baffles 42 are usually made of metal or other solid materials and have certain strength and stability. The extending direction of these baffles 42 is the same as the width direction of the drum 21, so as to ensure that the taro can move smoothly and remain on the conveyor belt 41 during the conveying process. The setting of the baffles 42 can prevent the taro from sliding or tilting during the conveying process, and improve the stability and accuracy of the conveying. The taro will be firmly supported on each baffle under the action of its own gravity, and the long taro vines are not easy to stay on the baffles 42, but will slide down the conveyor belt 41 back to the ground. That is, the baffles 42 can play the role of supporting and transporting the taro, and effectively separate the taro from the vines.

[0062] In some embodiments, the length of the baffle 42 is the same as the width of the conveyor belt 41, that is, the extension length of the baffle on the conveyor belt 41 is the same as the width of the conveyor belt 41, and blocking structures are provided at both ends of the conveyor belt 41, which can effectively prevent the taro delivered onto the conveyor belt 41 from detaching from the conveyor belt 41 from both sides of the baffle again.

[0063] In some embodiments, the conveyor belt 41 is a hollow structure. During the transportation process of the conveyor belt 41, soil clods and some long vines will leak from the through holes of the conveyor belt 41 to the ground.

[0064] In some embodiments, the extension portion 221 has the same width as the hook portion 222. That is, the sharpener 22 can be made by bending a blade during the manufacturing process, that is, the sharpener 22 is integrally formed.

[0065] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
