Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a non-destructive tuber harvesting device for konjac. Background Technology

[0002] When planting konjac, spot sowing or row sowing is generally used, with a sowing depth of 5-10 cm. This allows the konjac bulbs to receive sufficient soil protection, which is beneficial to their root growth.

[0003] Utility model patent CN222263650U discloses an adjustable konjac digging roller-type soil removal device. This device includes a konjac digging frame, with a rotating adjustment shaft rotatably connected inside the frame. A digging shovel is fixedly connected to the rotating adjustment shaft. Rotating blocks are rotatably connected to both sides of the konjac digging frame, and circular cards are fixedly connected to the rotating blocks. Each circular card has multiple slots. Nuts clamp the circular cards and the side walls of the konjac digging frame, thus fixing the angle of the rotating adjustment shaft and the angle position of the digging shovel. This allows for digging konjac at different depths. When the digging shovel deflects at an angle, the connection point between the circular card and the konjac digging frame is higher than the digging shovel, reducing contact between the pin and nut and the ground, thus reducing resistance and preventing loose connections that could cause the digging shovel angle to shift.

[0004] The current device has a shallow digging depth when digging konjac, which means that some konjac tubers are at a depth similar to that of the digging shovel head. This makes them easy to break during digging, resulting in a waste of resources. In view of this, we propose a non-destructive digging device for konjac tuber harvesting. Utility Model Content

[0005] The purpose of this invention is to provide a non-destructive tuber harvesting device for konjac, in order to solve the problems mentioned in the background art.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figures 1-6 The non-destructive digging equipment for konjac tuber harvesting includes a frame 1. A fixed shaft 11 is located at the front end of the frame 1, and several shovel blades 111 are mounted on the fixed shaft 11. A traction rod 12 is hinged to the top of the frame 1, allowing for flexible angle adjustments and adaptability to various traction power sources, such as tractors. The equipment moves within the konjac planting area via the traction power source. During the equipment's movement, the shovel blades 111 initially break and loosen the surface soil, enabling the konjac tubers to be dug out. A digging mechanism 2 is installed at the front end of the frame 1, comprising a pair of shovel arms 21, several shovel plates 22, and a second rotating rod 23.

[0041] like Figures 1-3 As shown, a pair of bosses 13 are fixed to the top of the frame 1. A first rotating rod 14 is rotatably connected between the two bosses 13. The two bosses 13 are respectively passed through at both ends of the first rotating rod 14. A first end post 142 is fixed at both ends of the first rotating rod 14. The bosses 13 provide stable support and a fulcrum for the first rotating rod 14. The outer diameter of the first end post 142 is larger than the inner diameter of the boss 13 for mounting the first rotating rod 14, thereby restricting the axial movement of the first rotating rod 14 and preventing the first rotating rod 14 from coming out of the bosses 13.

[0042] like Figure 1 and Figure 2As shown, guide plates 15 are fixed to the bottom edges of both sides of the frame 1. The bottom surface of the guide plates 15 is in contact with the ground. The guide plates 15 are made of steel plates with a smooth and flat surface, resulting in low friction when in contact with the ground. During the movement of the equipment, the guide plates 15 can slide along the ground. Utilizing their symmetrical structural characteristics, they constrain the direction of movement of the equipment, reducing deviations caused by uneven ground or external forces. At the same time, the guide plates 15 share part of the weight of the frame 1, increasing the contact area between the equipment and the ground, reducing the pressure exerted by the equipment on the ground, and providing support to keep the equipment stable during excavation operations.

[0043] like Figure 1 , Figure 2 and Figure 4 As shown, two shovel arms 21 are hinged to the left and right sides of the front end of the frame 1, respectively. The soil insertion depth of the foremost part of the shovel arm 21 is greater than that of the shovel blade 111. Several shovel plates 22 are arranged longitudinally and evenly between the two shovel arms 21. The shovel arms 21 are connected to the frame 1 through hinge points and have a certain degree of freedom of movement. During the excavation process, the angle can be adaptively adjusted according to the soil resistance to ensure smooth excavation. The larger soil insertion depth of the shovel arms 21 allows the konjac near the excavation depth of the shovel blade 111 to be dug out in advance by the digging mechanism 2 composed of the shovel arms 21 and shovel plates 22, effectively preventing the konjac from being broken or damaged by the subsequent shovel blade 111. A connecting plate 221 is provided between the several shovel plates 22. The connecting plate 221 passes through the several shovel plates 22 and is fixedly connected to them. The connecting plate 221 connects the dispersed shovel plates 22 into a whole, enhancing the connection strength between the shovel plates 22 and improving the overall rigidity of the digging mechanism 2, making it less prone to deformation during the excavation process.

[0044] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, an extension arm 211 is fixed to the end of the shovel plate 22. A second rotating rod 23 is located between the two extension arms 211 and is rotatably connected to the extension arms 211. The two ends of the second rotating rod 23 pass through the two extension arms 211 respectively, and a second end post 232 is fixed to both ends of the second rotating rod 23. The second end post 232 is fixed to both ends of the second rotating rod 23 in a similar way to the first end post 142. Its function is to prevent the second rotating rod 23 from coming out of the extension arms 211 during rotation.

[0045] like Figure 1 , Figure 2 and Figure 6As shown, an adjusting screw 3 is provided between the first rotating rod 14 and the second rotating rod 23. A screw hole 141 is provided at the middle position of the first rotating rod 14. The head end of the adjusting screw 3 passes through the screw hole 141 and is threadedly connected to the first rotating rod 14, so that the adjusting screw 3 is threadedly connected to the first rotating rod 14 through the screw hole 141. The threaded connection between the adjusting screw 3 and the first rotating rod 14 constitutes a screw drive mechanism. When the operator rotates the adjusting screw 3, the adjusting screw 3 will move axially in the screw hole 141 due to the action of the thread.

[0046] like Figure 5 and Figure 6 As shown, a through hole 231 is provided at the middle position of the second rotating rod 23, and a convex shaft 31 is provided at the end of the adjusting screw 3. The convex shaft 31 passes through the through hole 231, so that the end of the adjusting screw 3 is rotatably connected to the second rotating rod 23. A stop post 311 is fixed at the end of the convex shaft 31. The diameter of the stop post 311 is larger than the diameter of the through hole 231, so that the stop post 311 can effectively prevent the adjusting screw 3 from disengaging from the second rotating rod 23.

[0047] like Figure 6 As shown, a rotating lever 32 is provided on the adjusting screw 3. The rotating lever 32 passes vertically through the adjusting screw 3. After the rotating lever 32 and the adjusting screw 3 are fixed together, they form a cross-shaped operating structure, which provides the operator with a large lever arm. According to the lever principle, the operator only needs to apply a small force to generate a large torque, so as to rotate the adjusting screw 3 more easily and conveniently.

[0048] In this embodiment, the non-destructive tuber digging equipment for konjac harvesting first connects to a tractor or other traction power source via a tow rod 12 during konjac harvesting. The traction power source drives the equipment to move within the konjac planting area. At this time, the digging mechanism 2 plays the main digging role. Then, during the equipment's movement, the shovel arm 21 drives the longitudinally evenly spaced shovel plates 22 to penetrate deeper into the soil. Due to the depth advantage of the shovel arm 21, the konjac tubers close to the digging depth of the shovel plates 111 are first scooped up by the shovel plates 22, preventing these tubers from being broken by the shovel plates 111 and increasing the yield of the konjac tubers. To ensure the integrity of the excavation, when it is necessary to adjust the depth of the digging mechanism 2's insertion into the soil, the operator rotates the rotating lever 32 on the adjusting screw 3. According to the principle of screw transmission, the adjusting screw 3 moves axially in the screw hole 141 of the first rotating rod 14. Since the end of the adjusting screw 3 is rotatably connected to the second rotating rod 23, the axial movement of the adjusting screw 3 will drive the second rotating rod 23 to rotate, thereby causing the digging mechanism 2, which is connected to the second rotating rod 23, to rotate around the hinge point on the frame 1, changing the depth of the digging mechanism 2's insertion into the soil. In this way, the working depth of the digging mechanism 2 can be precisely adjusted according to different konjac planting depths, soil textures, and other actual conditions, improving the equipment's applicability.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
