Description

Technical Field

[0001] This utility model relates to the field of novel rhizome and stem medicinal material harvesting machines, and more specifically, to a novel rhizome and stem medicinal material harvesting machine. Background Technology

[0002] Rhizome harvesters are specialized machines used to harvest herbs or rhizome parts of medicinal plants. These machines are typically designed to automate and optimize the harvesting process to improve production efficiency and reduce labor costs. Rhizome medicinal plants come in a variety of forms, and harvesting machines usually need to be able to adapt to different plant shapes and growing environments. For example, some medicinal plants may require gentle harvesting methods to avoid damaging the plant. Harvesters may be equipped with automated control systems that can operate autonomously based on preset parameters and sensor feedback. This includes functions such as collecting, processing, and sorting medicinal plants, aiming to improve the efficiency and quality of medicinal plant production and make it more in line with market demands and standards.

[0003] The utility model patent with application number 202220262152.9 relates to a root and rhizome harvesting machine with a highly efficient soil purification function. Its rear soil purification component is composed of two pressure rollers, and the structure is relatively complex. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a novel rhizome harvesting machine that overcomes or at least partially solves the above technical problems.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a novel rhizome harvesting machine. A transmission assembly is provided below the frame, comprising a first transmission roller, a second transmission roller, and a chain plate. The first and second transmission rollers are located at opposite ends of the chain plate, and a pressure roller is provided above the second transmission roller. The chain plate comprises a transverse shaft and chain pieces, with adjacent chain pieces alternately stacked end-to-end. The transverse shaft passes through the alternately stacked portion of the chain pieces. The second transmission roller has radial toothed rings and radial concave rings, with the chain pieces corresponding to the radial concave rings. The convex teeth of the radial toothed rings correspond to the gaps between the chain pieces and the transverse shaft.

[0007] Further optimization involves rotating plates at both ends of the pressure roller. One end of the rotating plate is fitted onto a fixed shaft, and a first sprocket is located at the end of the fixed shaft. A second sprocket is located on the central shaft of the pressure roller. The first and second sprockets are connected by a chain. The other end of the rotating plate is connected to the bearing seats at both ends of the central shaft of the pressure roller. A fixed frame is connected between the two rotating plates. The piston rod of the hydraulic cylinder is connected to a spring plate, which is mounted on the fixed frame.

[0008] Further optimization involves providing crossbars on the outside of the pressure roller, with the crossbars arranged along the axial direction of the pressure roller, and multiple crossbars evenly distributed circumferentially along the outer side of the pressure roller.

[0009] Further optimization involves installing load-bearing bars on the outer side of the rotating plate, which are then placed above the frame.

[0010] The present invention provides a novel rhizome harvesting machine, the beneficial effects of which include:

[0011] 1. The second transmission roller of this utility model is provided with a radial toothed ring and a radial concave ring. The chain pieces correspond to the radial concave rings, and the convex teeth of the radial toothed rings correspond to the gaps between the chain pieces and the transverse shaft. The radial concave rings are used to position the chain pieces, and the transverse shaft is used to connect the chain pieces. The chain pieces can rotate around the transverse shaft. During the rotation of the second transmission roller, the radial toothed rings are used to drive the chain plates.

[0012] 2. The second transmission roller with the special structure described in this utility model forms a compaction roller with the pressure roller, which can clean the medicinal materials at the rear of the transmission process. Compared with the prior art, this utility model saves one pressure roller and has a relatively simple structure.

[0013] 3. The piston rod of the utility model hydraulic cylinder extends and retracts, lifting the fixed frame and causing the pressure roller to rotate around the connecting shaft between the rotating plate and the fixed shaft. At this time, the gap between the pressure roller and the second transmission roller is adjusted. If the medicinal materials encounter large objects during transmission, the elastic buffering pressure of the spring plate can crush the large pieces of material. After the large pieces of material are crushed, the gap between the pressure roller and the second transmission roller returns to normal. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] This utility model provides a technical solution: a novel rhizome and stem harvesting machine, with a transmission component located below the frame. For details, please refer to the attached specification. Figure 1 The transmission assembly includes a first transmission roller 1, a second transmission roller 2, and a chain plate 3. The first transmission roller 1 and the second transmission roller 2 are located at opposite ends of the chain plate 3, and a pressure roller 4 is positioned above the second transmission roller 3. The first transmission roller 1 and the second transmission roller 2 drive the transmission chain plate 3, which in turn transports the medicinal materials backward. (See attached instruction manual.) Figure 6 and Figure 7 As shown, the chain plate 3 includes a transverse shaft 31 and chain pieces 32, with adjacent chain pieces 32 stacked alternately end to end, and the transverse shaft 31 passing through the alternating stacked portion of the chain pieces. See the appendix to the specification. Figure 4 and Figure 5As shown, the second transmission roller 2 is provided with a radial toothed ring 21 and a radial concave ring 22. The chain piece 32 corresponds to the radial concave ring 22, and the protruding teeth of the radial toothed ring 21 correspond to the gaps between the chain piece and the transverse shaft. The radial concave ring 22 is used to position the chain piece, and the transverse shaft is used to connect the chain piece. The chain piece can rotate around the transverse shaft. During the rotation of the second transmission roller 2, the radial toothed ring 21 is used to drive the chain plate 3.

[0027] The second transmission roller 2 with its special structure described in this specific embodiment forms a compaction roller with the pressure roller 4, which can clean the medicinal materials at the rear of the transmission process. Compared with the prior art, this specific embodiment saves one pressure roller, and the structure is relatively simple.

[0028] To adjust the gap between the second transmission roller 2 and the pressure roller 4 to accommodate soil clods of different sizes, the following technical solution is adopted (see appendix to the instruction manual). Figure 8 and Figure 9 As shown: The pressure roller 4 has rotating plates 51 at both ends. One end of the rotating plate 51 is fitted onto a fixed shaft 52. A first sprocket 53 is located at the end of the fixed shaft 52, and a second sprocket 54 is located on the central shaft of the pressure roller 4. The first sprocket 53 and the second sprocket 54 are connected by a chain. The other end of the rotating plate 51 is connected to bearing seats 55 at both ends of the central shaft of the pressure roller 4. A fixed frame 56 connects the two rotating plates 51. The piston rod of the hydraulic cylinder 57 is connected to a spring plate 58, which is mounted on the fixed frame 56. In this specific embodiment, the extension and retraction of the piston rod of the hydraulic cylinder 57 can lift the fixed frame, causing the pressure roller 4 to rotate around the connecting shaft between the rotating plate 51 and the fixed shaft 52. At this time, the gap between the pressure roller 4 and the second transmission roller 2 is adjusted. When the medicinal material encounters a large object during transmission, the elastic buffering pressure of the spring plate 58 can crush the large material. After the large material is crushed, the gap between the pressure roller 4 and the second transmission roller 2 returns to normal.

[0029] See the attached instruction manual. Figure 2 and Figure 3 As shown, the pressure roller 4 is provided with crossbars 41 on its outside. The crossbars 41 are arranged along the axial direction of the pressure roller 4, and multiple crossbars 41 are evenly distributed circumferentially along the outer side of the pressure roller 4. When the pressure roller 4 rotates, the collision between the crossbars 41 and the chain plate on the second transmission roller 2 and the medicinal materials can play a good crushing role.

[0030] See the attached instruction manual. Figure 9 As shown, a load-bearing rod 59 is provided on the outer side of the rotating plate 51. When not in operation, the load-bearing rod 59 is placed on top of the frame, and the frame supports the load-bearing rod 59, reducing the burden of the pressure roller 4 on the hydraulic cylinder 57.
