Description

Technical Field

[0001] This invention relates to the field of agricultural and forestry machinery technology, and more specifically, to a weeding structure and device for weeding between medicinal plants under forest cover. Background Technology

[0002] Understory cultivation of medicinal herbs is an ecological agricultural model that utilizes the natural conditions of the forest environment (such as shade, humidity, and soil characteristics) to cultivate medicinal herbs suitable for growth under these conditions. This approach not only helps protect forest ecosystems but also improves land utilization and increases farmers' income. Common understory medicinal herbs include, but are not limited to: Coptis chinensis (Huanglian): Prefers cool and humid environments and is suitable for cultivation in semi-shade or full shade. Panax notoginseng (Sanqi): Prefers shade and moisture, does not tolerate strong sunlight, and is suitable for growth in environments with some shade. Gastrodia elata (Tianma): Has low light requirements and prefers moist humus soil. Ginseng: Prefers shade and moisture and typically grows naturally in mountain forests.

[0003] The cultivation of medicinal herbs under forest cover requires standardized and large-scale operations in all aspects, from site selection and land preparation to seedling cultivation, planting, water and fertilizer management, and pest and disease control. Among these, weeds compete with medicinal herbs for limited natural resources and can become hosts for pathogens and pests, reducing the intrinsic quality of the herbs. Therefore, effective weed control is necessary during land preparation and daily management.

[0004] With the development of technology, weeding has evolved from manual weeding to mechanical weeding. Various types of weeding machines have appeared on the market, effectively improving weeding efficiency. The existing weeding machines are mainly of the mowing type and the rotary tiller type. The mowing type mainly cuts and crushes the parts of grass above the root stem. Because the cultivation of Chinese medicinal herbs requires strict quality control, 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. Moreover, the long-term presence of weed roots may change the physical structure of the soil, such as increasing soil compaction, affecting the expansion and respiration of the roots of Chinese medicinal herbs. Therefore, the rotary tiller type of weeding equipment is preferred for the cultivation of Chinese medicinal herbs. That is, the rotating blades are driven into the soil to crush the soil and bring out the weeds and grass roots at the same time, and then the weeds and grass roots are collected and processed.

[0005] However, while the aforementioned weeding equipment turns the soil to remove weed roots, it cannot effectively return the soil attached to the roots to the planting area. When collecting weeds and roots, it also collects the soil along with them, resulting in a small loss of soil in the planting area. This requires manual soil filling and fertilization, increasing the workload of planting and, in severe cases, even affecting the planting quality of medicinal herbs. Summary of the Invention

[0006] The present invention provides a weeding structure and device for weeding between medicinal plants under forest cover. The problem to be solved is that although existing weeding equipment turns the soil to remove grass roots during weeding, the soil attached to the grass roots is also collected when weeds and grass roots are collected together, resulting in a small amount of soil loss in the planting area. This requires manual soil filling and fertilization, which increases the workload of planting and may even affect the planting quality of medicinal plants in severe cases.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a weeding structure for interplants of Chinese medicinal herbs under forest cover, comprising a soil loosening component and a grass collecting component. The grass collecting component includes a filtering and conveying component and a grass collecting container. The soil loosening component, the filtering and conveying component, and the grass collecting container are distributed sequentially along the weeding path. The soil loosening component includes a power shaft, on which multiple sets of rotary tillage blades are installed.

[0008] The filter conveying assembly is inclined and its top extends into the grass collection container. The filter conveying assembly includes a belt-type circulating conveyor and a conveying drive. At least two sets of conveying drive are provided. The belt-type circulating conveyor is arranged around the two sets of conveying drive. The belt-type circulating conveyor is supported by the two sets of conveying drive to form a circulating conveying assembly. The belt-type circulating conveyor has an upper inclined surface and a lower inclined surface under the support of the two sets of conveying drive. The upper inclined surface is used to carry the mixture of soil and weeds and convey it into the grass collection container.

[0009] The surface of the belt-type circulating conveyor is provided with a filtration space, which is used to filter and separate weeds and grass roots in the soil.

[0010] In a preferred embodiment, the belt-type circulating conveyor includes a conveyor chain and chain connecting rods. At least two sets of conveyor chains are provided, and multiple chain connecting rods are provided. The multiple chain connecting rods are distributed along the circumference of the conveyor chain, and the two ends of the chain connecting rods are fixedly connected to the conveyor chain. The conveying drive body is a drive sprocket, which cooperates with the conveyor chain and is driven to rotate by a rotation drive device.

[0011] In a preferred embodiment, the belt-type circulating conveyor is a conveyor belt, the conveying drive is a drive belt roller, the drive belt roller is driven to rotate by a rotation drive device, thereby driving the conveyor belt to form a conveying motion, and the filtration space is a filter hole provided on the conveyor belt.

[0012] In a preferred embodiment, the grass-collecting assembly further includes a wind pressure hood, which is disposed on the upper inclined surface of the belt circulating conveyor and the port of the wind pressure hood is disposed corresponding to the surface of the belt circulating conveyor. An air blowing pipe is fixedly connected to the wind pressure hood and is connected to an air supply unit. A heating component is also installed inside the wind pressure hood.

[0013] In a preferred embodiment, the heating assembly consists of multiple sets of hollow heating rollers. The hollow heating rollers are rotatably installed inside the wind pressure cover. The axial direction of the hollow heating rollers is perpendicular to the conveying direction of the belt circulating conveyor, and the axial direction of the hollow heating rollers is parallel to the inclined surface of the belt circulating conveyor. Each hollow heating roller is arranged to gradually approach the belt circulating conveyor along the conveying direction of the inclined surface of the belt circulating conveyor. The hollow heating rollers have a hollow structure, and a heating structure is provided inside the hollow heating rollers.

[0014] In a preferred embodiment, the surface of the belt-type circulating conveyor is further provided with multiple sets of grass-blocking protrusions, which are evenly distributed on the surface of the belt-type circulating conveyor. The inside of the grass-collecting container is provided with an air extraction hood, which is connected to the air extraction unit through a pipe. A filter baffle is provided at the air extraction port of the air extraction hood, and the filter baffle is aligned with the conveying drive body above.

[0015] In a preferred embodiment, multiple sets of air knife structures are fixedly installed at the bottom of the inner walls on both sides of the wind pressure hood. The air outlet of the air knife structure is a flat air outlet. The air knife structure is set close to the surface of the belt-type circulating conveyor. Air knife equalization channels are provided on the outside of both sides of the wind pressure hood. The air knife structure is connected to the air knife equalization channel. The air knife equalization channel is connected to an air supply unit through a pipe. The air knife structures on both sides of the wind pressure hood are staggered.

[0016] In a preferred embodiment, the outer wall of the belt-type circulating conveyor is provided with a flexible belt layer, which is wound around the outside of the belt-type circulating conveyor. Corresponding holes are provided on the flexible belt layer at the positions of the filter holes. The flexible belt layer is relatively loosely disposed on the outside of the belt-type circulating conveyor. The grass-blocking protrusions penetrate the flexible belt layer and slide with the flexible belt layer.

[0017] In a preferred embodiment, the grass collection assembly further includes a sweeping assembly, which includes a sweeping brush roller driven to rotate by a rotation drive device. Multiple sets of sweeping rods are evenly arranged on the surface of the sweeping brush roller, and the sweeping rods are arranged at the positions where the filter conveying assembly contacts the ground.

[0018] A weeding device for interplants of Chinese medicinal herbs under forest cover includes a walking machine, which is a small walking device. The bottom of the walking machine is equipped with walking wheels, and the walking machine is equipped with an operating unit. The soil loosening component, the filtering and conveying component, the grass collection container, the sweeping component and the wind pressure cover are all installed on the walking machine.

[0019] The soil loosening component is located at the front end of the walking machinery. The power shaft is rotatably mounted on the walking machinery. Both ends of the power shaft are equipped with medicinal herb shielding discs, which are arc-shaped structures.

The air extraction hood and filter baffle are both fixedly installed in the walking machine. When the hay collection container is engaged and installed inside the walking machine, the air extraction hood and filter baffle are located in the inner cavity of the hay collection container.

[0022] The beneficial effects of this invention are as follows: After the soil loosening component loosens the soil, the invention drives a belt-type circulating conveyor to circulate and transport the loose soil, along with weeds and grass roots, upwards. During the upward transport process, soil fragments and particles can be filtered downwards and pass through the lower inclined surface of the belt-type circulating conveyor, falling back to the ground. Meanwhile, weeds and grass roots continue to be transported upwards with the movement of the belt-type circulating conveyor until they reach the grass collection container. This achieves weeding in the medicinal herb planting area without removing most of the original soil, greatly reducing soil loss in the planting area, preserving the original soil nutrients to the maximum extent, reducing subsequent maintenance work, and improving the planting efficiency and quality of medicinal herbs.

[0035] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0036] Refer to the instruction manual appendix Figures 1 to 11 A weeding structure for interplanting medicinal herbs under forest cover includes a soil loosening component 1 and a weeding component. The weeding component includes a filtering and conveying component 2 and a weeding container 3. The soil loosening component 1, the filtering and conveying component 2, and the weeding container 3 are distributed sequentially along the weeding path. The soil loosening component 1 includes a power shaft 11, on which multiple sets of rotary tillage blades 12 are installed. The power shaft 11 is driven to rotate by a rotary drive device. During weeding, the rotation of the power shaft 11 drives the rotary tillage blades 12 to rotate into the soil, loosening the soil and bringing out the weeds and their roots. At the same time, larger weeds are crushed. The belt-type circulating conveyor 21 follows closely behind the soil loosening component 1. After the soil loosening component 1 crushes the ground soil and the weeds are lifted up along with their roots, the weeds are collected.

[0037] Specifically, the filter conveying assembly 2 is inclined, and its top extends into the grass collection container 3. The filter conveying assembly 2 includes a belt-type circulating conveyor 21 and a conveying drive 22. At least two sets of conveying drive 22 are provided. The belt-type circulating conveyor 21 is arranged around the two sets of conveying drive 22. The belt-type circulating conveyor 21 is supported by the two sets of belt-type circulating conveyor 22 to form a circulating conveying assembly. For details, refer to various conveying assemblies in industrial production, such as conveyor belts. The surface of the belt-type circulating conveyor 21 is provided with a filtration space for filtering and separating weeds and grass roots in the soil. The belt-type circulating conveyor 21 is supported by the two sets of conveying drive 22 to form a circulating conveying assembly. The inclined surface is used to carry the mixture of soil and weeds and convey it into the grass collection container 3 (i.e., the upper set of conveying drive 22 extends into the grass collection container 3). In actual use, after the loosening assembly 1 loosens the soil, the lower conveying drive 22 extends into the soft soil. In the soil, the belt-type circulating conveyor 21 is driven to circulate, which can transport the loose soil along with weeds and grass roots upward. During the upward transport, the soil is in the form of fragments after being processed by the soil loosening component 1, while the weeds and grass roots, although also crushed, are relatively flexible and therefore mainly in the form of long strips, making it difficult to pass through the filtration 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, falling back to the ground. 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 collection container 3. When the conveyor drive body 22 turns at the top, the weeds and grass roots automatically fall downward and are collected in the grass collection container 3. This achieves weeding in the Chinese medicinal herb planting area without taking away most of the original soil, greatly reducing soil loss in the planting area, preserving the original soil nutrients to the greatest extent, reducing the amount of subsequent maintenance work, and improving the planting efficiency and quality of Chinese medicinal herbs.

[0038] It should be noted that in the above embodiments, the soil loosening component 1 is a rotary tillage type soil loosening and weeding device commonly used in the field of agricultural planting. Therefore, its specific driving method and related structure will not be explained in detail in this embodiment. In addition to the soil loosening component 1 provided in this embodiment, other soil loosening and weeding machines commonly used in the field can also be used.

[0039] Furthermore, in this embodiment, the filter conveying assembly 2 is mainly a conveying structure with a filtering function, for example, referring to the appendix of the specification. Figure 4This embodiment provides a conveying scheme for a belt-type circulating conveyor 21 and a conveying drive 22. The belt-type circulating conveyor 21 includes a conveyor chain 2101 and chain connecting rods 2102. At least two sets of conveyor chains 2101 are provided, while multiple chain connecting rods 2102 are provided. The multiple chain connecting rods 2102 are distributed along the circumference of the conveyor chain 2101, and both ends of the chain connecting rods 2102 are fixedly connected to the conveyor chain 2101. The conveying drive 22 is a drive sprocket 221. The drive sprocket 221 cooperates with the conveyor chain 2101, and the drive sprocket 221 is driven to rotate by a rotation drive device, thereby driving the belt-type circulating conveyor 21 to perform conveying motion. A filtering space is formed between two adjacent chain connecting rods 2102.

[0040] The above solution uses metal workpieces to make the conveyor chain 2101 and chain connecting rod 2102, which is relatively durable. However, the filtration space between two adjacent chain connecting rods 2102 is large, resulting in poor filtration effect. Therefore, this embodiment also provides another conveying solution for the belt circulating conveyor 21 and conveyor drive 22. For details, please refer to the appendix of the instruction manual. Figure 5 The belt-type circulating conveyor 21 is a conveyor belt 2103, the conveyor drive 22 is a drive belt roller 222, the drive belt roller 222 is driven to rotate by a rotation drive device, thereby driving the conveyor belt 2103 to form a conveying motion, and the filtration space is a filter hole 211 set on the conveyor belt 2103 (that is, a filter hole 211 set on the belt-type circulating conveyor 21).

[0041] Further, please refer to the appendix to the instruction manual. Figures 1 to 3 The grass collection component also includes a sweeping component 4, which includes a sweeping brush roller 41. The sweeping brush roller 41 is driven to rotate by a rotation drive device. Multiple sets of sweeping rods 42 are evenly arranged on the surface of the sweeping brush roller 41. The sweeping rods 42 are set at the positions where the filter conveying component 2 contacts the ground. By driving the sweeping brush roller 41 to rotate, the sweeping rods 42 can sweep a large amount of weeds above the ground onto the belt circulating conveyor 21 (for details, refer to various sweeping mechanisms), thereby improving the efficiency of weed recovery. At the same time, the sweeping rods 42 can also extend into the loose soil to stir, improve the separation efficiency of grass roots and soil, and reduce the adhesion between soil and weeds.

[0042] In the above embodiments, since the weeding time is relatively fixed and the soil is relatively moist due to the influence of the external environment (soil is damp in rainy or snowy weather, which is not suitable for loosening and weeding, but soil moisture will vary depending on air humidity and the weather conditions before the day), the soil is also relatively moist after loosening. In addition, the soil near the grass roots has a high water content, causing the soil to adhere to the weeds and grass roots. Therefore, even though the above solution can filter out a large amount of soil, some soil will still be unable to pass through the filter space (i.e., filter holes 211) along with the weeds and grass roots. To address this, this embodiment also provides the following technical solution, specifically referring to the appendix to the specification. Figure 6 The grass-collecting assembly also includes a wind pressure hood 6, which is located on the upper inclined surface of the belt-type circulating conveyor 21. The port of the wind pressure hood 6 is positioned corresponding to the surface of the belt-type circulating conveyor 21. An air blowing pipe 61 is fixedly connected to the wind pressure hood 6, and the air blowing pipe 61 is connected to an air supply unit. Specifically, the air supply unit includes an air pump. In actual use, the air pump supplies air to the wind pressure hood 6, so that the port of the wind pressure hood 6 has an airflow perpendicular to the upper inclined surface of the belt-type circulating conveyor 21. This airflow can pass through the filter holes 211 and penetrate the upper and lower inclined surfaces of the belt-type circulating conveyor 21. Smaller soil particles can be easily carried away. At the same time, the airflow can also dry the soil particles. During the upward transport of soil and weeds, the moist soil is gradually dried and can then be filtered downward with the airflow. Meanwhile, soil particles attached to the surface of grass roots are also easier to detach, improving the soil separation effect.

[0043] 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, thereby effectively heating the internal space of the wind pressure hood 6 and, together with the airflow inside the wind pressure hood 6, accelerating the drying of the soil, thereby improving the filtration efficiency.

[0044] In the above embodiments, if the soil loosening component 1 has a high degree of pulverization, the weeds and grass roots will also be pulverized to a relatively high degree. The weeds and grass roots will be relatively small and easily pass through the filter space back to the ground. However, if the soil loosening component 1 has a low degree of pulverization, more soil clumps will appear and combine with the grass roots, making them difficult to separate. Therefore, this embodiment also provides the following technical solutions, specifically referring to the appendix to the specification. Figure 7The heating assembly 62 consists of multiple sets of hollow heating rollers 621. The hollow heating rollers 621 are rotatably mounted inside the wind pressure shroud 6. The axial direction of the hollow heating rollers 621 is perpendicular to the conveying direction of the belt conveyor 21, and the axial direction of the hollow heating rollers 621 is parallel to the inclined surface of the belt conveyor 21. Each hollow heating roller 621 is arranged sequentially and gradually approaches the belt conveyor 21 along the conveying direction of the inclined surface. The hollow heating rollers 621 have a hollow structure, and a heating element is arranged inside each hollow heating roller 621. The hollow heating roller 621 forms a direct heating body by means of a structure (such as an electric heating rod, a fluid heater, etc.). During the conveying process, the soil and weeds can gradually come into contact with the hollow heating roller 621 and be squeezed by the hollow heating roller 621 as it gradually approaches the belt-type circulating conveyor 21. This can crush relatively large soil clods. At the same time, the hollow heating roller 621 heats the inside of the wind pressure cover 6. When the hollow heating roller 621 directly contacts the soil clods, it can quickly heat the moist soil clods and squeeze them at the same time, thereby improving the processing efficiency of moist soil.

[0045] In the above embodiments, to further improve the separation effect of grass roots and soil, please refer to the appendix to the instruction manual. Figures 7 to 9 The surface of the belt-type circulating conveyor 21 is also provided with multiple sets of grass-blocking protrusions 212. The grass-blocking protrusions 212 are evenly distributed on the surface of the belt-type circulating conveyor 21. In actual use, complex grass roots are easy to get caught on the grass-blocking protrusions 212, which can reduce the phenomenon that the soil clods on the grass roots are too large to be carried onto the belt-type circulating conveyor 21. At the same time, when the hollow heating roller 621 squeezes the soil clods, 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 hanging on them, which helps the soil clods crushed by the hollow heating roller 621 to detach from the grass roots.

[0046] Further, please refer to the appendix to the instruction manual. Figure 7 and Figure 10Multiple sets of air knife structures 63 are fixedly installed on the bottom of the inner walls on both sides of the wind pressure hood 6. The air outlet of the air knife structure 63 is a flat air outlet. The air knife structure 63 is set close to the surface of the belt circulating conveyor 21. Air knife equalization channels 64 are set on the outside of both sides of the wind pressure hood 6. The air knife structure 63 is connected to the air knife equalization channel 64. The air knife equalization channel 64 is connected to an air supply unit (which can be connected to the same air supply unit as the blowing pipe 61) through a pipe. The air knife structures 63 on both sides of the wind pressure hood 6 are staggered. In actual use, the air knives on both sides All structures 63 can blow out lateral airflow, and this lateral airflow adheres to the surface of the belt-type circulating conveyor 21. While increasing the air pressure inside the wind pressure hood 6 and increasing the effect of the airflow ultimately penetrating the belt-type circulating conveyor 21 downwards, the lateral airflow can also disturb the grass roots on the surface of the belt-type circulating conveyor 21. Furthermore, the air knife structures 63 on both sides are staggered. Therefore, during the upward conveying of grass roots, when the grass roots are caught by the grass-blocking protrusions 212, the grass roots can be made to swing left and right, improving the soil removal effect.

[0047] Further, please refer to the appendix to the instruction manual. Figure 6 The inside of the grass-collecting container 3 is equipped with an exhaust hood 31, which is connected to an exhaust unit via a pipe. A filter baffle 32 is installed at the exhaust port of the exhaust hood 31, and the filter baffle 32 is aligned with the conveyor drive body 22 above. In actual use, the exhaust hood 31 can form a transverse airflow in the top area of ​​the belt-type circulating conveyor body 21. This transverse airflow helps weeds and grass roots to detach laterally from the belt-type circulating conveyor body 21, reducing the adhesion of weeds and grass roots to the belt-type circulating conveyor body 21. At the same time, the soil dust remaining on the belt-type circulating conveyor body 21 and on the weeds and grass roots can be drawn away through the filter baffle 32. The exhaust unit is preferably an exhaust pump, and a filter structure can be installed on the exhaust pipe to finally discharge the filtered dust into the medicinal herb planting area.

[0048] In the above embodiments, in order to improve the carrying effect of lighter grass roots and weeds, weed-blocking protrusions 212 are provided on the surface of the belt circulating conveyor 21. However, if the grass roots are more complex, the degree of entanglement on the weed-blocking protrusions 212 is high, and they are not easy to detach later. Therefore, this embodiment also provides the following technical solutions, which are detailed in the appendix to the specification. Figure 11The outer wall of the belt-type circulating conveyor 21 is provided with a flexible belt layer 213, which is wrapped around the outside of the belt-type circulating conveyor 21. Corresponding holes are also provided on the flexible belt layer 213 at the positions of the filter holes 211, which will not affect the filtration effect. At the same time, the flexible belt layer 213 is relatively loosely positioned on the outside of the belt-type circulating conveyor 21. The grass-blocking protrusions 212 penetrate the flexible belt layer 213 and slide with it. The flexible belt layer 213 is affected by gravity in the upper inclined surface area of ​​the belt-type circulating conveyor 21 and is attached to the belt-type circulating conveyor 21. The grass-blocking protrusions 212 protrude from the surface of the flexible belt layer 213. At this time, the flexible belt layer 213 has a carrying effect on grass roots, especially when passing through the wind pressure hood 6. Under the action of airflow, the flexible belt layer 213 adheres more tightly to the belt-type circulating conveyor 21. At the lower inclined surface of the belt-type circulating conveyor 21, under its own weight, the flexible belt layer 213 will move downward, that is, a gap will be created with the belt-type circulating conveyor 21 (especially under the blowing of the airflow output from 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 protrusions 212 are relatively retracted into the flexible belt layer 213. Therefore, when passing over the conveyor drive body 22 above, Afterwards, the flexible belt layer 213 detaches from the belt-type circulating conveyor 21. At this time, the grass roots that were originally wrapped around the weed-blocking protrusions 212 are more likely to detach and fall into the grass collection container 3 (because the filter conveyor assembly 2 is set at an angle, the upper conveyor drive 22 is basically located in the grass collection container 3, so the weeds that have passed the upper conveyor drive 22 will still fall into the grass collection container 3). This can maximize the soil recycling efficiency and reduce the probability of weeds and grass roots falling back, improve the weed removal effect in the Chinese medicinal herb planting area, and maximize the satisfaction of the growth needs of Chinese medicinal herbs.

[0049] In the above embodiments, the medicinal plants in some medicinal herb planting areas are relatively densely packed, with little space between adjacent rows of plants. This is especially true for understory medicinal herb planting, where the working space is limited and large machinery is not suitable. Therefore, please refer to the appendix to the instruction manual. Figures 1 to 3 Based on the above-mentioned weeding device, this embodiment also provides a weeding device for interplants of Chinese medicinal herbs under forest cover, including a walking machine 5. The walking machine 5 is a small walking device, such as a small tractor or an automatic walking vehicle. The bottom of the walking machine 5 is provided with walking wheels 51, and the walking machine 5 is provided with an operating part 52, such as a handle and a control lever. The soil loosening component 1, the filter conveying component 2, the grass collection container 3, the sweeping component 4, and the wind pressure cover 6 are all provided on the walking machine 5.

[0050] Specifically, the soil loosening component 1 is located at the front end of the walking machine 5, the power shaft 11 is rotatably mounted on the walking machine 5, the filter conveying component 2 is located at the bottom of the walking machine 5, the conveying drive body 22 is rotatably mounted in the walking machine 5, the sweeping brush roller 41 is rotatably mounted in the walking machine 5, and the wind pressure cover 6 is fixedly mounted inside the walking machine 5.

[0051] The walking machine 5 is provided with a slot structure for engaging with the grass collection container 3. The grass collection container 3 is engaged in the filter conveying assembly 2 through the slot structure. The air extraction hood 31 and the filter baffle 32 are both fixedly installed in the walking machine 5. When the grass collection container 3 is engaged in the walking machine 5, the air extraction hood 31 and the filter baffle 32 are located in the inner cavity of the grass collection container 3.

[0052] It should be noted that the movement of the traveling machinery 5 can be driven by electricity or a small engine. For the drive of the power shaft 11, a small engine is preferred due to its stronger power. The rotation drive of the sweeping brush roller 41 and the conveying drive body 22 can be driven by a transmission assembly connected to the output shaft of the small engine in the loosening assembly 1, or by a motor structure. If a motor structure is used, a corresponding battery assembly needs to be installed on the traveling machinery 5. Regarding the heating structure inside the hollow heating roller 621, when the entire device uses a small engine, the exhaust end of the small engine can be connected to the inner cavity of the hollow heating roller 621. Simultaneously with the exhaust of the small engine, the exhaust gas is... Heat exchange is performed in the hollow heating roller 621 to achieve the 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 appropriate size of the walking machine 5, as well as the soil loosening component 1, the filter conveying component 2, etc., can be selected according to the specific spatial effect of the Chinese medicinal herb planting area. This embodiment will not explain in detail. In order to avoid the Chinese medicinal herbs being accidentally damaged when the soil loosening component 1 is working, medicinal herb shielding discs 13 can be set at both ends of the power shaft 11. The medicinal herb shielding discs 13 have an arc-shaped structure. Thus, when the device is walking, the medicinal herb shielding discs 13 can be used to block the Chinese medicinal herbs outside the rotary tillage area of ​​the power shaft 11, thereby reducing damage to the Chinese medicinal herbs.
