Description

Technical Field

[0001] This utility model belongs to the technical field of Chinese medicinal herb harvesting machines, specifically a lightweight and efficient Chinese medicinal herb harvesting machine for shallow and medium-sized rhizomes. Background Technology

[0002] In the field of Chinese medicinal herb cultivation, the planting scale of shallow-rooted herbs is gradually expanding. These herbs, such as Corydalis, Pinellia, and Arisaema, mostly grow in sandy loam and shallow soil layers, but their harvesting process faces many challenges. Traditional harvesting methods, such as manually rakeing and picking by hand, are not only extremely labor-intensive but also have very low production efficiency, resulting in high harvesting costs and seriously affecting the economic benefits of medicinal herb cultivation.

[0003] Existing harvesters for root and rhizome medicinal herbs mostly use a single transmission structure for their lifting system, resulting in poor power transmission stability. They are prone to overload damage when encountering soil clumping or impurities, and the digging shovel is fixed and cannot be replaced. This makes them unsuitable for different soil types and medicinal herb types, thus limiting overall operating efficiency.

[0004] Therefore, a simple and efficient harvesting machine for shallow and medium-sized rhizomes of Chinese medicinal herbs is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a lightweight and efficient harvester for shallow and medium-sized rhizomes of Chinese medicinal herbs. It has the advantages of reducing the frequency of mechanical failures, increasing the continuous operation time of the machine, improving digging efficiency, enabling quick shovel changes, and enhancing adaptability to different operating scenarios.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight and efficient harvester for shallow-rooted medicinal herbs, comprising a harvester body, a ground wheel mounted at the bottom of the harvester body, a traction part, a replaceable digging shovel connected to one side of the traction part, the replaceable digging shovel being detachably connected to the harvester body by bolts, a gearbox provided on one side of the harvester body, a primary lifting device fixedly connected to the output end of the gearbox to provide power to the primary lifting device, a secondary lifting device being driven by the primary lifting device, a gear reversing mechanism fixedly connected to the output end of the secondary lifting device, a soil-crushing roller drive sprocket connected to the secondary lifting device through the gear reversing mechanism, the soil-crushing roller drive sprocket being driven by an adjustable soil-crushing roller, and a soil-shaking roller and a transition roller fixedly connected to the output end of the secondary lifting device.

[0007] Preferably, the output end of the gearbox is fixedly connected to a primary lifting drive sprocket, and the output end of the gearbox is fixedly connected to a primary lifting device via the primary lifting drive sprocket. The primary lifting drive sprocket is a drive sprocket with a protector.

[0008] Preferably, the side plates of the harvester body frame are made of low-carbon alloy steel.

[0009] Preferably, a traction diagonal rod is provided on one side of the harvester body, and the traction part is connected to the harvester body through the traction diagonal rod.

[0010] Preferably, the replaceable digging shovel is used in conjunction with the primary and secondary lifting shovels for digging and lifting Chinese medicinal materials, and the replaceable digging shovel can be switched to a "W-shaped" digging shovel or a "straight" digging shovel.

[0011] Preferably, the adjustable soil-crushing roller is used to crush the excavated soil.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a gearbox, selects a sprocket with a protector when the gearbox outputs the transmission to the first stage of the lifting chain. When the load increases instantaneously, the protector activates, and the power transmission fails momentarily. When the fault is manually cleared and the load returns to normal, the power transmission resumes normally. The use of a drive sprocket with a protector can effectively prevent the performance failure of various components caused by the instantaneous increase in load, thereby reducing the frequency of mechanical failures of the machine, increasing the continuous operation time of the machine, and improving digging efficiency.

[0013] 2. This utility model connects the excavating shovel and the machine with bolts. With the convenience of bolt disassembly and assembly, the excavating shovel can be quickly switched according to different working conditions, realizing rapid shovel replacement and improving adaptability to different working scenarios.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] like Figures 1 to 5 As shown, this utility model provides a lightweight and efficient harvester for shallow and medium-sized rhizomes of Chinese medicinal herbs, including a harvester body 1, with a ground wheel 2 installed at the bottom of the harvester body 1; The harvester body 1 includes a traction unit 3. A replaceable digging shovel 4 is connected to one side of the traction unit 3. The replaceable digging shovel 4 is detachably connected to the harvester body 1 by bolts. A gearbox 5 is provided on one side of the harvester body 1. A primary lifting conveyor 6 is fixedly connected to the output end of the gearbox 5, providing power to the primary lifting conveyor 6. The primary lifting conveyor 6 is driven by a secondary lifting conveyor 7. A gear reversing mechanism 8 is fixedly connected to the output end of the secondary lifting conveyor 7. The secondary lifting conveyor 7 is connected to a soil-crushing roller drive sprocket 13 through the gear reversing mechanism 8. The soil-crushing roller drive sprocket 13 is driven by an adjustable soil-crushing roller 9. A soil-shaking roller 10 and a transition roller 11 are fixedly connected to the output end of the secondary lifting conveyor 7. By detachably connecting the replaceable digging shovel 4 to the harvester body 1 by bolts, the continuous operation of digging and soil crushing can be realized under the coordinated action of various components. This also provides a basis for flexibly adjusting the components according to the working conditions, improving the adaptability of the machine operation.

[0018] Specifically, the output end of the gearbox 5 is fixedly connected to a first-stage lifting drive sprocket 12. The output end of the gearbox 5 is fixedly connected to the first-stage lifting device 6 through the first-stage lifting drive sprocket 12. The first-stage lifting drive sprocket 12 is a drive sprocket with a protector. By setting the first-stage lifting drive sprocket 12 with a protector between the gearbox 5 and the first-stage lifting device 6, the protector can cut off the power transmission in time when the load increases instantaneously, so as to avoid damage to core components such as the gearbox 5 and the first-stage lifting device 6 due to overload, reduce mechanical failures, and ensure continuous operation of the machine.

[0019] like Figures 1 to 5 As shown, the side plates of the harvester body 1 are made of low-carbon alloy steel. By selecting low-carbon alloy steel to make the side plates of the harvester body 1, the structural strength of the frame and its ability to withstand operational impacts are ensured, while also taking into account the overall lightweight design of the machine. This lays the foundation for adapting the implements to small-power tractors and improving the flexibility of field movement.

[0020] Furthermore, a traction diagonal rod 14 is provided on one side of the harvester body 1. The traction part 3 is connected to the harvester body 1 through the traction diagonal rod 14. By setting the traction diagonal rod 14 to connect the traction part 3 and the harvester body 1, the traction force can be distributed during traction operation, reducing the connection stress between the traction part 3 and the body, improving the overall traction stability, and preventing the parts from deforming due to uneven force during operation.

[0021] like Figures 1 to 5 As shown, the interchangeable digging shovel 4 works in conjunction with the primary lifting 6 and the secondary lifting 7 to dig and transport Chinese medicinal herbs. The interchangeable digging shovel 4 can be switched between a "W-shaped" digging shovel and a "straight" digging shovel. Through the cooperation of the interchangeable digging shovel 4 with the primary lifting 6 and the secondary lifting 7, it supports the switching between "W-shaped" and "straight" shovel bodies. Under different soil textures and root and stem morphologies of medicinal herbs, it can efficiently dig Chinese medicinal herbs and transport them to subsequent processes, while reducing damage to the herbs during the digging process and improving the harvest quality.

[0022] It is worth noting that the adjustable soil crushing roller 9 is used to crush the excavated soil.

[0023] Working principle and process: When the machine is in operation, the tractor transmits power to the gearbox 5 through the universal joint. The gearbox 5 drives the first-stage lifting sprocket 12 to drive the first-stage lifting 6. The first-stage lifting 6 further transmits to the second-stage lifting 7. The second-stage lifting 7 drives the adjustable soil-crushing roller 9 to rotate through the gear reversing mechanism 8 and the soil-crushing roller drive sprocket 13 to crush the excavated soil. On the other hand, it drives the soil-shaking roller 10 and the transition roller 11. At the same time, after the replaceable digging shovel 4 excavates the Chinese medicinal materials, it transports the mixture of Chinese medicinal materials and soil to the subsequent process through cooperation with the first-stage lifting 6 and the second-stage lifting 7, realizing continuous operation of excavation, lifting and crushing.

[0024] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
