Description

Technical Field

[0001] The present invention relates to the technical field of agricultural and forestry machinery, and more specifically, to a weeding structure and a weeding device between Chinese medicinal materials under forests. Background Art

[0002] Planting Chinese medicinal materials under the forest is an ecological agricultural model that uses the natural conditions of the forest environment (such as shade, humidity and soil characteristics) to grow Chinese medicinal materials suitable for growing under these conditions. This approach not only helps to protect the forest ecosystem, but also improves land utilization and increases farmers' income. Common Chinese medicinal materials under the forest include but are not limited to: Coptis chinensis: It prefers a cool and humid environment and is suitable for planting in semi-shaded or full-shaded areas. Panax notoginseng: It likes shade and humidity, is not resistant to strong light, and is suitable for growing in an environment with a certain shade. Gastrodia elata: It has low light requirements and prefers moist humus soil. Ginseng: It likes shade and humidity and usually grows naturally in mountain forests.

[0003] Planting Chinese medicinal materials under forests requires standardized and large-scale operations in various links, including site selection, land preparation, seed and seedling raising, planting, water and fertilizer management, and pest and disease control. Among them, weeds compete with Chinese medicinal materials for limited natural resources, and weeds can become hosts for pathogens and pests, reducing the intrinsic quality of Chinese medicinal materials. Therefore, weeds need to be effectively removed during land preparation and daily management.

[0004] With the development of science and technology, manual weeding has evolved into today's mechanical weeding. A variety of weeders have appeared on the market, which effectively improved the weeding efficiency. The existing weeders mainly include mowing type and rotary tillage type. The mowing type mainly cuts and crushes the grass above the rhizome. Due to the strict quality control of Chinese medicinal materials cultivation, and many weeds have strong vitality, even if the above-ground parts are removed, their roots can still survive and germinate again under suitable conditions, and the long-term existence of weed roots may change the physical structure of the soil, such as increasing the compaction of the soil, affecting the expansion and respiration of the roots of Chinese medicinal materials. Therefore, rotary tillage weeding equipment is preferred for Chinese medicinal materials cultivation, that is, it uses a rotating blade to rotate into the soil, crushing the soil while bringing out weeds and grass roots, and then collecting and processing the weeds and grass roots.

[0005] However, although the above-mentioned weeding equipment will turn the soil to turn the grass roots out of the soil during weeding, the soil attached to the grass roots cannot be effectively returned to the planting area. When the weeds and grass roots are recovered, the associated soil will be taken away together, resulting in a small amount of soil loss in the planting area. Manual soil filling and fertilization are required, which increases the planting workload and may even affect the planting quality of Chinese medicinal materials in severe cases. Summary of the invention

[0006] The present invention provides an understory Chinese medicinal material weeding structure and weeding device, and aims to solve the following problem: when weeding, the existing weeding equipment will turn the soil to turn the grass roots out of the soil, but the soil attached to the grass roots will be collected together when the weeds and grass roots are recovered, resulting in a small amount of soil loss in the planting area, and manual soil filling and fertilization are required, which increases the planting workload and may even affect the planting quality of Chinese medicinal materials in severe cases.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] Refer to the instruction manual Figures 1 to 11 A weeding structure between Chinese medicinal materials under the forest, comprising a loosening component 1 and a grass collecting component, the grass collecting component comprising a filtering and conveying component 2 and a grass collecting container 3, the loosening component 1, the filtering and conveying component 2 and the grass collecting container 3 are sequentially distributed along a weeding path, the loosening component 1 comprises a power shaft 11, on which are mounted a plurality of groups of rotary tillage blades 12, the power shaft 11 being driven to rotate by a rotary driving device, during weeding, the power shaft 11 rotates to drive the rotary tillage blades 12 to rotate into the soil, and while loosening the soil, the weeds and grass roots are taken out, and at the same time, the larger weeds are crushed, and the belt-type circulating conveyor 21 closely follows the loosening component 1, and after the loosening component 1 crushes the ground soil and the weeds are taken up with their roots, the weeds are collected.

[0031] Specifically, the filtering and conveying assembly 2 is inclined, and the top end of the filtering and conveying assembly 2 extends into the grass collecting container 3. The filtering and conveying assembly 2 includes a belt-type circulating conveying body 21 and a conveying driving body 22. At least two groups of conveying driving bodies 22 are arranged. The belt-type circulating conveying body 21 is arranged around the two groups of conveying driving bodies 22. The belt-type circulating conveying body 21 is supported by the two groups of belt-type circulating conveying bodies 21 to form a circulating conveying assembly. For details, reference can be made to various conveying assemblies in industrial production, such as conveyor belts and other structures. Among them, a filtering space is provided on the surface of the belt-type circulating conveying body 21. The filtering space is used to filter and separate weeds and grass roots in the soil. The belt-type circulating conveying body 21 is supported by the two groups of conveying driving bodies 22 to form a circulating conveying assembly. The upper inclined surface is used to carry a mixture of soil and weeds and convey it to the grass collecting container 3 (that is, a group of conveying driving bodies 22 located above extends into the grass collecting container 3). In actual use, after the loosening assembly 1 loosens the soil, the conveying driving body 22 located below extends into the soft The belt-type circulating conveyor 21 is driven to circulate in the soil, and the soft soil together with the weeds and grass roots can be transported upward. In the process of upward transportation, the soil is in the form of fragments after being processed by the loosening component 1, and although the weeds and grass roots are also crushed, they are relatively flexible and mainly in the form of long strips, which makes it difficult for them to pass through the filtering space on the belt-type circulating conveyor 21. Therefore, the soil fragments and particles can be filtered downward and pass through the lower inclined surface of the belt-type circulating conveyor 21 and fall back to the ground, while the weeds and grass roots continue to be transported upward with the movement of the belt-type circulating conveyor 21 until they reach the grass collecting container 3. When turning at the upper conveying driving body 22, the weeds and grass roots automatically fall downward and fall into the grass collecting container 3 for collection, thereby achieving weeding in the Chinese medicinal material planting area without taking away most of the soil in the original area, greatly reducing soil loss in the planting area, retaining soil nutrients in the original area to the greatest extent, reducing subsequent maintenance workload, and improving the Chinese medicinal material planting efficiency and the quality of Chinese medicinal material products.

[0032] It should be noted that in the above-mentioned embodiment, the loosening component 1 is a rotary tillage loosening and weeding equipment commonly used in the agricultural planting field, so its specific driving method and related structure are not explained in detail in this embodiment. In addition to the method of the loosening component 1 provided in this embodiment, other commonly used loosening and weeding machines in this field can also be used.

[0033] Further, in this embodiment, the filter conveying assembly 2 is mainly a conveying structure with a filtering function, for example, referring to the attached Figure 4The present embodiment provides a conveying scheme of a belt-type circulating conveyor body 21 and a conveying driving body 22. The belt-type circulating conveyor body 21 includes a conveying chain 2101 and a chain connecting rod 2102. At least two groups of conveying chains 2101 are provided, and a plurality of chain connecting rods 2102 are provided. The plurality of chain connecting rods 2102 are distributed along the circumference of the conveying chain 2101, and the two ends of the chain connecting rod 2102 are respectively fixedly connected to the conveying chain 2101. The conveying driving body 22 is a driving sprocket 221. The driving sprocket 221 cooperates with the conveying chain 2101, and the driving sprocket 221 is driven to rotate by a rotating driving device, thereby driving the belt-type circulating conveyor body 21 to perform conveying movement, and a filtering space is formed between two adjacent chain connecting rods 2102.

[0034] The above scheme can use metal workpieces to make the conveyor chain 2101 and the chain connecting rod 2102, which is relatively durable, but the filtering space between two adjacent chain connecting rods 2102 is large, and the filtering effect is poor. For this reason, this embodiment also provides another conveying scheme of the belt-type circulating conveyor 21 and the conveying driving body 22. For details, refer to the attached manual. Figure 5 The belt-type circulating conveyor body 21 is a conveyor belt 2103, and the conveying driving body 22 is a driving belt roller 222. The driving belt roller 222 is driven to rotate by a rotating driving device, thereby driving the conveyor belt 2103 to form a conveying motion. The filtering space is a filtering hole 211 arranged on the conveyor belt 2103 (that is, the filtering hole 211 arranged on the belt-type circulating conveyor body 21).

[0035] For further information, please refer to the attached manual. Figures 1 to 3 The grass collecting component also includes a cleaning component 4, which includes a cleaning brush roller 41. The cleaning brush roller 41 is driven to rotate by a rotating drive device. A plurality of cleaning rods 42 are evenly arranged on the surface of the cleaning brush roller 41. The cleaning rods 42 are arranged corresponding to the position where the filtering and conveying component 2 contacts the ground. Then, by driving the cleaning brush roller 41 to rotate, the cleaning rods 42 can be driven to clean a large amount of weeds above the ground onto the belt-type circulating conveying body 21 (for details, please refer to various cleaning mechanisms), thereby improving the recovery efficiency of the weeds. At the same time, the cleaning rods 42 can also be extended into the soft soil for stirring, thereby improving the separation efficiency of the grass roots and the soil and reducing the connection between the soil and the weeds.

[0036] In the above embodiment, since the weeding time is relatively fixed and affected by the external environment, the soil is relatively moist (the soil is moist in rainy and snowy weather and is not suitable for loosening and weeding operations, but the soil moisture may vary due to the air humidity and the weather conditions before the day). The soil after loosening is also relatively moist. In addition, the water content near the grass roots is relatively high, and the soil will adhere to the weeds and grass roots. Therefore, even if a large amount of soil can be filtered out by the above scheme, some soil will follow the weeds and grass roots and cannot pass through the filtering space (i.e., the filtering holes 211). For this reason, the present embodiment also provides the following technical solutions. For details, refer to the attached manual. Figure 6 The grass collecting component also includes a wind pressure hood 6, which is arranged at the upper inclined surface of the belt-type circulating conveying body 21, and the port of the wind pressure hood 6 corresponds to the surface of the belt-type circulating conveying body 21. A blowing pipe 61 is fixedly connected to the wind pressure hood 6, and the blowing pipe 61 is connected to an air supply unit. Specifically, the air supply unit includes an air pump. In actual use, air is supplied to the wind pressure hood 6 by the air pump, so that there is an airflow perpendicular to the upper inclined surface of the belt-type circulating conveying body 21 at the port of the wind pressure hood 6, and the airflow can pass through the upper inclined surface and the lower inclined surface of the belt-type circulating conveying body 21 through the filter hole 211. For smaller soil particles, they can be easily taken away. At the same time, the airflow can also dry the soil particles. In the process of transporting the soil and weeds upward, the moist soil is gradually dried, and then can be filtered downward with the airflow. At the same time, the soil particles attached to the surface of the grass roots are also easier to detach, thereby improving the soil separation effect.

[0037] Furthermore, in order to improve the drying effect on grass roots and soil, a heating component 62 is also installed inside the wind pressure hood 6. The heating component 62 can be a commonly used electric heating device, or other heating devices can be used to effectively heat the internal space of the wind pressure hood 6, and cooperate with the airflow in the wind pressure hood 6 to accelerate the drying of the soil, thereby improving the filtration efficiency.

[0038] In the above embodiment, if the degree of crushing of the loosening component 1 is too high, the degree of crushing of weeds and grass roots is also relatively high, and the weeds and grass roots are relatively small and easy to pass through the filter space back to the ground. Therefore, if the degree of crushing of the loosening component 1 is low, more soil blocks will appear and combine with the grass roots, making it difficult to separate. Therefore, this embodiment also provides the following technical solutions, specifically, refer to the attached manual Figure 7The heating assembly 62 is composed of a plurality of hollow heating rollers 621, which are rotatably mounted inside the wind pressure cover 6. The axial direction of the hollow heating rollers 621 is perpendicular to the conveying direction of the belt-type circulating conveyor 21, and the axial direction of the hollow heating rollers 621 is parallel to the inclined surface of the belt-type circulating conveyor 21. Each hollow heating roller 621 is arranged gradually close to the belt-type circulating conveyor 21 along the conveying direction of the inclined surface of the belt-type circulating conveyor 21. The hollow heating rollers 621 are hollow structures, and a heating structure is arranged inside the hollow heating rollers 621. The hollow heating roller 621 is a direct heating body, and the soil and weeds can gradually contact with the hollow heating roller 621 during the transportation process, and be squeezed in sequence by the hollow heating roller 621 which gradually approaches the belt-type circulating conveying body 21, so that relatively large soil blocks can be crushed. When the hollow heating roller 621 heats the inside of the wind pressure hood 6, the hollow heating roller 621 directly contacts the soil blocks, and can quickly heat the wet soil blocks and squeeze them at the same time, thereby improving the processing efficiency of the wet soil.

[0039] In the above embodiment, in order to further improve the separation effect of grass roots and soil, refer to the attached manual. Figures 7 to 9 The surface of the belt-type circulating conveyor 21 is also provided with a plurality of groups of grass-blocking protrusions 212, which are evenly distributed on the surface of the belt-type circulating conveyor 21. In actual use, complex grass roots are easily hung on the grass-blocking protrusions 212, thereby reducing the phenomenon that the mud blocks on the grass roots are large and difficult to be brought onto the belt-type circulating conveyor 21. At the same time, when the hollow heating roller 621 squeezes the mud blocks, the conveying of the belt-type circulating conveyor 21 causes the grass-blocking protrusions 212 to have a forward pulling force on the grass roots hung thereon, which helps the mud blocks crushed by the hollow heating roller 621 to separate from the grass roots.

[0040] For further information, please refer to the attached manual. Figure 7 and Fig.10, multiple groups of wind knife structures 63 are fixedly installed at the bottom of the inner walls on both sides of the wind pressure hood 6, the air outlet of the wind knife structure 63 is a flat air outlet, the wind knife structure 63 is arranged close to the surface of the belt-type circulating conveyor 21, and wind knife air distribution channels 64 are arranged on the outside of both sides of the wind pressure hood 6. The wind knife structure 63 is connected to the wind knife air distribution channel 64, and the wind knife air distribution channel 64 is connected to an air supply unit through a pipeline (the same air supply unit as the air blowing pipe 61 can be connected). The wind knife structures 63 on both sides of the wind pressure hood 6 are staggered with each other. When actually used, the wind knives on both sides The structures 63 can blow out lateral airflow, and the lateral airflow fits the surface of the belt-type circulating conveyor body 21. While increasing the internal air pressure of the wind pressure hood 6 and increasing the effect of the airflow eventually penetrating downward through the belt-type circulating conveyor body 21, the lateral airflow can also have a disturbing effect on the grass roots on the surface of the belt-type circulating conveyor body 21. The wind knife structures 63 on both sides are staggered. Therefore, in the process of upward conveying of the grass roots, when the grass blocking convex nails 212 hang on the grass roots, the grass roots can be made to swing left and right, thereby improving the soil separation effect.

[0041] For further information, please refer to the attached manual. Figure 6 The interior of the grass collecting container 3 is provided with an exhaust hood 31, and the exhaust hood 31 is connected to the exhaust unit through a pipeline. A filter baffle 32 is provided at the exhaust port of the exhaust hood 31, and the filter baffle 32 is arranged to align with the conveying driving body 22 above. Therefore, in actual use, a lateral airflow can be formed in the top area of ​​the belt circulating conveyor 21 through the exhaust hood 31, and the lateral airflow helps the weeds and grass roots to separate laterally from the belt circulating conveyor 21, thereby reducing the attachment of weeds and grass roots to the belt circulating conveyor 21. At the same time, the soil dust remaining on the belt circulating conveyor 21 and on the weeds and grass roots can be extracted through the filter baffle 32. The exhaust unit is preferably an exhaust pump, and a filtering structure can be provided on the exhaust pipeline to finally discharge the filtered dust into the Chinese medicinal material planting area.

[0042] In the above embodiment, in order to improve the carrying effect of lighter grass roots and weeds, grass blocking protruding spikes 212 are provided on the surface of the belt-type circulating conveyor 21. However, if the grass roots are relatively complex, the degree of entanglement on the grass blocking protruding spikes 212 is relatively high, and it is not easy to separate later. Therefore, this embodiment also provides the following technical solutions. For details, refer to the attached manual. Fig.11The outer wall of the belt-type circulating conveyor 21 is provided with a flexible belt layer 213, and the flexible belt layer 213 is wound around the outside of the belt-type circulating conveyor 21. Corresponding holes are also provided on the flexible belt layer 213 at the positions corresponding to the filter holes 211, which will not affect the filtering effect. At the same time, the flexible belt layer 213 is relatively loosely arranged outside the belt-type circulating conveyor 21. The grass-blocking convex nails 212 penetrate the flexible belt layer 213 and slide with the flexible belt layer 213. The flexible belt layer 213 is affected by gravity in the upper inclined surface area of ​​the belt-type circulating conveyor 21 and is arranged to fit the belt-type circulating conveyor 21. The grass-blocking convex nails 212 protrude from the surface of the flexible belt layer 213. At this time, the flexible belt layer 213 has a carrying effect on the grass roots, especially when passing through the wind pressure hood 6. Under the action of the airflow, the flexible belt layer 213 is closer to the belt-type circulating conveyor 21, and at the lower inclined surface of the belt-type circulating conveyor 21, under the weight of the flexible belt layer 213 itself, the flexible belt layer 213 will move downward, that is, a gap will be generated with the belt-type circulating conveyor 21 (especially under the blowing of the output airflow of the wind pressure hood 6, the flexible belt layer 213 located on the outer side below is blown outward). At this time, the grass blocking convex nail 212 is relatively retracted into the flexible belt layer 213. Therefore, when passing over the upper conveying driving body 22 After that, the flexible belt layer 213 is separated from the belt-type circulating conveyor body 21. At this time, the grass roots originally entangled in the grass-blocking convex nails 212 are more likely to be separated and fall into the grass collecting container 3 (because the filtering and conveying component 2 is tilted, the upper conveying driving body 22 is basically located in the grass collecting container 3, so the weeds that pass the upper conveying driving body 22 will still fall into the grass collecting container 3), thereby maximizing the soil recovery efficiency and reducing the probability of weeds and grass roots falling back, thereby improving the weed removal effect in the Chinese medicinal material planting area and meeting the growth needs of Chinese medicinal materials to the greatest extent.

[0043] In the above implementation, the Chinese medicinal materials plants in some Chinese medicinal materials planting areas are relatively dense, and the space between two adjacent rows of plants is small, especially for Chinese medicinal materials planting under the forest, where the working space is limited and it is not suitable to use large equipment. Therefore, please refer to the attached manual. Figures 1 to 3 Based on the above-mentioned weeding device, this embodiment also provides a weeding device between plants of Chinese medicinal materials under the forest, including a walking machine 5, which is a small walking device, such as a small tractor, an automatic walking car, etc., and a walking wheel 51 is arranged at the bottom of the walking machine 5. The walking machine 5 is provided with a control part 52, such as a hand handle and a joystick, etc., and the loosening component 1, the filtering and conveying component 2, the grass collecting container 3, the cleaning component 4 and the wind pressure hood 6 are all arranged on the walking machine 5.

[0044] Specifically, the loosening assembly 1 is located at the front end of the walking machine 5, the power shaft 11 is rotatably installed on the walking machine 5, the filtering and conveying assembly 2 is arranged at the bottom of the walking machine 5, the conveying driving body 22 is rotatably installed in the walking machine 5, the cleaning brush roller 41 is rotatably installed in the walking machine 5, and the wind pressure hood 6 is fixedly installed in the walking machine 5.

[0045] A slot structure for engaging with the grass collecting container 3 is provided in the walking machine 5. The grass collecting container 3 is installed in the filtering and conveying assembly 2 through the slot structure. The exhaust hood 31 and the filter baffle 32 are both fixedly installed in the walking machine 5. When the grass collecting container 3 is engaged and installed inside the walking machine 5, the exhaust hood 31 and the filter baffle 32 are located in the inner cavity of the grass collecting container 3.

[0046] It should be noted that, the walking machine 5 can be driven by electric drive or by a small engine, and the driving of the power shaft 11 is preferably driven by a small engine, which has stronger power. As for the rotation driving device of the cleaning brush roller 41 and the conveying driving body 22, a transmission component connected to the output shaft of the small engine of the loosening component 1 can be used as a rotation driving device for driving, or a motor structure can be used for rotation driving. If a motor structure is used for rotation driving, a corresponding battery assembly needs to be provided on the walking machine 5. As for the heating structure inside the hollow heating roller 621, when the device as a whole uses a small engine, the exhaust gas discharge end of the small engine can be connected to the inner cavity of the hollow heating roller 621. When the small engine is exhausted, the exhaust gas discharged in Heat exchange is carried out in the hollow heating roller 621 to achieve a heating effect. If the entire device is driven only by electric equipment, the heating structure inside the hollow heating roller 621 can directly use an electric heating rod structure. As for the walking machine 5, many small walking drive devices have appeared in the agricultural field. In actual use, the walking machine 5 and the loosening component 1, the filtering and conveying component 2, etc. of corresponding sizes can be selected according to the specific spatial effect of the Chinese medicinal materials planting area. This embodiment will not be explained in detail. In order to avoid accidental injury to the Chinese medicinal materials during the operation of the loosening component 1, a medicinal material shielding plate 13 can be set at both ends of the power shaft 11. The medicinal material shielding plate 13 is an arc-shaped structure. When the device is moving, the medicinal material shielding plate 13 can be used to block the Chinese medicinal materials outside the rotary tillage area of ​​the power shaft 11 to reduce damage to the Chinese medicinal materials.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
