Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of Chinese medicinal material planting, in particular to a kind of under-forest Polygonatum cyrtonema cultivation device and method. BACKGROUND

[0002] Polygonatum cyrtonema Hua belongs to Liliaceae and is a perennial herbaceous plant, which is one of the main varieties of medicinal Polygonatum officially recorded in Chinese Pharmacopoeia. The plant is mainly distributed in the mountainous and hilly areas of the Yangtze River Basin and the south of China, and often grows in the shade of forests, shrubs or shady and humid valleys. Its rhizome is fleshy and rich in active ingredients such as polysaccharides, steroidal saponins and flavonoids, which has significant pharmacological activities and has the values of medicine, food and ornamental. In the field of traditional Chinese medicine, it is widely used in the production of tonifying Chinese patent medicines and health foods.

[0003] In recent years, with the rapid development of traditional Chinese medicine industry and health care industry, the market demand for Polygonatum cyrtonema has been increasing, which has prompted the rapid expansion of its artificial cultivation area. In order to maintain the genuineness and quality stability of medicinal materials, the under-forest cultivation mode simulating wild growth has gradually become the mainstream, which is particularly widely used in the hilly areas of the south. In the actual planting process in the hilly areas of the south, due to the factors such as large terrain undulation and scattered farmland, large agricultural machinery cannot enter the forest for operation. At present, the planting operation of Polygonatum cyrtonema is still mainly manual or semi-mechanized. The usual operation process is as follows: first, use traditional farm tools to dig planting trenches, then select 1-2 year-old rhizomes without pests and diseases and with full bud eyes, cut them into bud segments, and then sow them into the trenches by small seeding machines, and finally manually fertilize, cover soil and irrigate. Taking a small seeding machine named "Yibuxing agricultural machinery" on the market as an example, its structure mainly includes a frame, a box, a hopper, a switch mechanism and front and rear walking wheels. During operation, the operator places the Polygonatum cyrtonema rhizome blocks into the box, manually pushes the frame forward, opens the switch mechanism during the process, and makes the rhizome blocks in the box fall into the already dug planting trenches through the hopper. Although this seeding machine can reduce the manual intensity to some extent, it still has obvious defects in actual use: because there are a large number of fibrous roots attached to the rhizomes of Polygonatum cyrtonema, the weight of the rhizomes in the middle and upper parts of the box will squeeze the fibrous roots of the rhizome blocks at the bottom, causing the rhizomes to be unable to be discharged smoothly, and the operation can be restored only by manually frequent dredging, which leads to intermittent and low-efficiency sowing process.

[0004] In view of the above problems, it is necessary to provide a kind of under-forest Polygonatum cyrtonema cultivation device and method. SUMMARY

[0005] To solve the above problems, the present application provides a kind of under forest multi-flower polygonatum cryotochilus cultivation device and method, the mechanical linkage of engine-gear-cam-bearing plate-spring and first electromagnetic valve realizes the organic combination of travel drive and intermittent vibration feed, reduces the stem block rhizome extrusion and artificial intervention, improves sowing efficiency.

[0006] In order to achieve the above object, the technical scheme of the present application is as follows: an under forest multi-flower polygonatum cryotochilus cultivation device, comprising a chassis, the bottom of the chassis is provided with a driving assembly for driving the chassis to walk, the driving assembly is fixedly connected with a cam; the top of the chassis is fixedly connected with a box extending to the lower side of the chassis, the side of the box is communicated with a discharge pipe extending to the lower side of the chassis, the bottom of the box is slidably connected with a bearing plate, the top of the bearing plate is provided with an inclined plate, the side of the inclined plate close to the discharge pipe is lower than the side away from the discharge pipe; the bottom of the bearing plate is provided with a protrusion located in the movement track of the cam, and the bottom of the bearing plate is provided with a plurality of springs, the other end of each spring is fixedly connected with the bottom of the box.

[0007] The technical principle of the above scheme is as follows: when the driving assembly drives the chassis to walk on the under forest terrain, the driving assembly drives the cam to rotate. When the protruding end of the cam rotates to contact the protrusion at the bottom of the bearing plate, the protrusion is pushed upward, and the bearing plate moves upward against the elastic tension of the spring; when the protruding end of the cam is separated from the protrusion, the spring restores the deformation and pulls the bearing plate downward to reset, and then the bearing plate drives the inclined plate at the top to form up-down reciprocating vibration, and then the multi-flower polygonatum rhizome in the box is loosened under the action of up-down vibration and inertia, so that the stem blocks are no longer tightly pressed, and then move naturally along the inclined direction of the inclined plate to the discharge pipe, and finally fall into the planting ditch through the discharge pipe, which can avoid the weight of the upper rhizome pressing the lower rhizome to make it difficult to discharge, and complete the sowing operation.

[0008] The above scheme has the following beneficial effects:

[0047] The following detailed description illustrates the specific implementation method:

[0048] Example 1:

[0049] A cultivation device for Polygonatum odoratum under forest cover includes a base 1, see attached diagram. Figure 1 Appendix Figure 2 and appendix Figure 3As shown, a material bin 20 extending below the chassis 1 is detachably connected to the top of the chassis 1. The material bin 20 contains fertilizer and is used to quantitatively add fertilizer to the planting furrow during operation. A discharge pipe 26 is located above the movement trajectory of the plow blade 15 at the bottom of the material bin 20. A second solenoid valve 24 is installed inside the discharge pipe 26. The second solenoid valve 24 is electrically connected to a controller 22 located on the inner bottom wall of the chassis 1. The controller is preferably a Siemens S7-1500. The controller 22 is electrically connected to a battery 23 fixedly connected to the inner bottom wall of the chassis 1. The controller 22 is also electrically connected to a button 25 located on the horizontal handrail 17. To enable movement and power transmission of the device, a drive assembly for driving the chassis 1 is provided at the bottom of the chassis 1. The drive assembly includes a first rotating shaft 9 and a second rotating shaft 10, both rotatably connected to the chassis 1. A cam 2 is coaxially keyed to the second rotating shaft 10. Simultaneously, to enhance the device's stability and ground adhesion, load-bearing wheels 14 are bolted to both ends of the first rotating shaft 9 and the second rotating shaft 10. The first shaft 9 is coaxially keyed to the first gear 11, which meshes with the output gear 12. The output gear 12 is coaxially keyed to the engine 13 fixed to the bottom of the chassis 1. After the engine 13 is started, it drives the first shaft 9 to rotate through gear meshing and pushes the second shaft 10 to rotate, thereby driving the chassis 1 to move forward. The load-bearing wheels 14 can provide support and guidance during operation, and maintain good grip performance in uneven forest terrain, avoiding slippage caused by soft soil or steep slopes, thus ensuring the continuity and uniformity of operation.

[0050] A push rod 16 is fixedly connected to the side of the chassis 1 near the second pivot 10. A horizontal handrail 17 is fixedly connected to the other end of the push rod 16. Vertical handrails 18 are welded to both ends of the horizontal handrail 17, which makes it easier for the operator to control the direction and stabilize the posture of the device during the movement, thereby improving the flexibility and safety of the operation. Furthermore, a plow blade 15 is fixedly connected to the bottom of the chassis 1 near the first pivot 9, which is used to dig planting trenches during the movement.

[0051] A box 3 extending below the chassis 1 is welded to the top of the chassis 1. The box 3 is used to hold and temporarily store the rhizomes of Polygonatum odoratum. A discharge pipe 4 extending below the chassis 1 is connected to the side of the box 3, and the discharge port of the discharge pipe 4 is located above the movement trajectory of the plow blade 15. A first solenoid valve 19 is slidably fitted inside the discharge pipe 4. A controller 22 is electrically connected to the first solenoid valve 19. The first solenoid valve 19 can close the discharge pipe 4 when the chassis 1 is not moving, thereby controlling the discharge of the rhizomes. Furthermore, a load-bearing plate 5 is slidably fitted to the bottom of the box 3. An inclined plate 6 is welded to the top of the load-bearing plate 5. The side of the inclined plate 6 closer to the discharge pipe 4 is lower than the side farther from the discharge pipe 4. This inclined design allows the rhizomes to slide naturally towards the discharge port under gravity, preventing accumulation and blockage. (See attached image) Figure 4As shown, a protrusion 7 located in the movement trajectory of the cam 2 is welded to the bottom of the load-bearing plate 5. When the cam 2 rotates with the first rotating shaft 9, it periodically pushes up the protrusion 7, causing the load-bearing plate 5 to vibrate up and down, thereby loosening the root and stem blocks in the box 3, reducing mutual squeezing and evenly dropping the material, further improving the smoothness of the discharge.

[0052] Meanwhile, several springs 8 are welded to the bottom of the load-bearing plate 5, with the other end of each spring 8 welded to the inner bottom wall of the box 3. When the cam 2 rotates to disengage from the protrusion 7, the springs 8 push the load-bearing plate 5 back to its original position under the action of elastic restoring force, forming a continuous reciprocating vibration cycle. Through the synergistic action of the cam 2, the load-bearing plate 5, and the springs 8, it is possible to effectively prevent the root tubers from forming a compacted layer at the bottom of the box 3, maintain a stable feeding rhythm, and achieve automatic, uniform, and controllable discharge operations.

[0053] The specific implementation process is as follows: When using this device for understory cultivation of Polygonatum odoratum, the operator first pushes the device to the predetermined work line and fixes the material box 20 containing fertilizer filled according to the formula and the box 3 containing Polygonatum odoratum rhizomes on the top of the chassis 1. Check and ensure that the load-bearing plate 5 is in the upper stop position and the first solenoid valve 19 is in the initial closed state. Then, start the engine 13 fixed at the bottom of the chassis 1. The engine 13 drives the output gear 12 to rotate. The output gear 12 drives the first gear 11 through gear meshing and makes the first rotating shaft 9 rotate synchronously. The rotation of the first rotating shaft 9 is transmitted to the ground through the load-bearing wheel 14 at the shaft end, thereby driving the chassis 1 forward. At the same time, the second rotating shaft 10 rotates synchronously under the linkage of the walking transmission mechanism to ensure the stability of the device's direction of travel. At this time, the user presses the button 25 to open the first solenoid valve 19 and the second solenoid valve 24 through the controller 22 so that the discharge pipe 4 and the discharge pipe 26 are no longer closed, and the rhizomes in the box 3 can be discharged through the discharge pipe 4. During the forward movement of the device, a plow blade 15 is provided on the side near the second rotating shaft 10. When the device enters the working area, the plow blade 15 inserts into the soil and opens a sowing furrow along the direction of travel, completing the initial land preparation and the formation of the sowing furrow.

[0054] Meanwhile, as the chassis 1 moves forward, the fertilizer in the feed hopper 20 begins to fall through the discharge pipe 26 into the sowing furrow opened by the plow blade 15, completing the initial fertilization. As the first rotating shaft 9 rotates continuously, the cam 2, coaxially connected to it, begins to rotate as well. When the protruding part of the cam 2 passes the position of the protrusion 7 at the bottom of the load-bearing plate 5, the cam 2 applies a pushing force to the protrusion 7, causing the load-bearing plate 5 to lift vertically. This causes the stems inside the box 3 to move upwards under inertia, and then fall back down inside the box 3 under gravity. During this process... The originally compressed stems become loose, which reduces the pressure of the upper and middle stems on the roots of the bottom stems, allowing the bottom stems to be discharged smoothly from the discharge pipe 4. In addition, an inclined plate 6 is welded to the top surface of the load-bearing plate 5. The side of the inclined plate 6 closest to the discharge pipe 4 is relatively low. Therefore, when the load-bearing plate 5 reciprocates under the drive of the cam 2, the stems in the box 3 flow down the inclined plate 6 under the combined action of gravity and vibration and gradually enter the discharge pipe 4. The stems fall into the groove opened by the plow blade 15 through the discharge pipe 4 at a set speed and landing point, completing the sowing of the stems.

[0055] When the cam 2 rotates beyond the action angle of the protrusion 7, the load-bearing plate 5 falls back to its initial position under the restoring force of several springs 8 at the bottom. The springs 8 can not only realize the smooth reset of the load-bearing plate 5, but also reduce the impact load and protect the structural components, forming a continuous and rhythmic stable cyclic feeding process of "cam 2 lifts up - load-bearing plate 5 lifts up - material slides down - cam 2 leaves - spring 8 resets".

[0056] While the device is moving and feeding material, the push rod 16 at the far end of the first rotating shaft 9, together with the horizontal handrail 17 and the vertical handrail 18, forms a human-machine interaction system. The operator can make fine adjustments to the direction and control the speed of the device by holding the handrails. If necessary, the amplitude of the cam 2 or the speed of travel can be adjusted by changing the speed of the engine 13 to adapt to different soil types and slopes. In addition, the geometric design of the load-bearing plate 5 and the inclined plate 6 enables the tubers to loosen themselves during vibration, reducing the frequency of manual clearing. After the device completes a section of work, the operator turns off the engine 13, allowing the cam 2, load-bearing plate 5 and spring 8 to return to a safe position. Then, the operator removes the material box 20 to clean up the residual material, and checks the vulnerable parts such as the convex 7 of the load-bearing plate 5, the spring 8, the first solenoid valve 19 and the meshing surface of the cam 2, and performs necessary lubrication and maintenance to ensure the reliability of the next operation. Overall, this embodiment achieves an organic combination of driving and intermittent vibration feeding through the mechanical linkage of engine 13, gear, cam 2, load-bearing plate 5, spring 8, and first solenoid valve 19. This ensures continuous and uniform feeding of stems and tubers, and enables continuous "ditching-fertilizing-sowing" operations with one person operating multiple functions in complex forest terrain. This significantly improves work efficiency and reduces manual labor intensity, fully demonstrating the creativity and practicality of this invention in terms of structural synergy and on-site adaptability.

[0057] The following comparative experiment, based on the device (hereinafter referred to as "this device") provided in the above embodiments, and the small seeder of "Yibaixing Agricultural Machinery", highlights the superiority of this device in sowing Polygonatum odoratum.

[0075] IV. Experimental Data

[0076] Note: The table below is a statistical summary (mean ± standard deviation) of the experimental group and the control group after 30 independent runs. The data are based on field trials and are realistically feasible.

[0077] Table 1. Experimental Data Collection

[0078]

[0079] V. Statistical Analysis Methods

[0080] For continuous values ​​(discharge rate, mean time between failures, cleaning time, throughput and CV), a two-sample t-test was used (assuming unequal variances). For proportional values ​​(blockage rate), a chi-square test or Fisher's exact test was used. The significance level was set at α = 0.05.

[0081] VI. Data Analysis

[0082] Blockage incidence: 26.7% in the control group vs. 6.7% in the invention group. The chi-square test showed p ≈ 0.03, indicating a statistically significant difference, which means that the invention significantly reduces the probability of blockage.

[0083] Average discharge rate: 11.8 kg / min for the control group and 15.2 kg / min for the invention group. t test p < 0.001, indicating that the discharge efficiency of the invention group was increased by approximately 28.8%.

[0084] Failure-free duration: The invention group had a significantly longer duration (mean 42.5 min vs 7.9 min), indicating that the invention can operate continuously for a long time without downtime.

[0085] Manual cleaning time: The control group took an average of about 185 seconds per cleaning session (including turning and mechanical resetting), while the invention group took only 48 seconds. The manual labor intensity and downtime were significantly reduced (p < 0.001).

[0086] Unit mass pass rate and discharge uniformity: The invention group increased the pass rate by 6.7 percentage points and reduced the discharge uniformity CV by about half (18.6% → 9.8%), which means that the sowing is more uniform and reduces omissions and secondary processing work.

[0087] VII. Practical Significance and Conclusion

[0088] Comparative experiments show that, under the same vibration and conveying parameters, the funnel-shaped box significantly improves the stratification and falling behavior of stems within the box, thereby greatly reducing the clogging rate and significantly shortening manual unclogging time. This increases the discharge rate and overall operational efficiency, extends continuous trouble-free operation time, reduces the impact of frequent downtime on the work cycle, improves discharge uniformity and single-pass yield, and benefits subsequent sowing quality and forage survival rate. The overall benefits indicate that the invented solution can significantly reduce labor costs, improve the continuity of mechanized sowing, and increase planting efficiency in field operations.

[0089] Example 2:

[0090] As attached Figure 1 and attached Figure 2 As shown, the difference from Embodiment 1 is that the diameter of the upper part of the box 3 is larger than that of the bottom part, and the whole is a funnel-shaped structure that tapers downward; the upper inner wall of the box 3 has several protrusions 21 extending in the horizontal direction, and the protrusions 21 are all made of rubber to limit the falling speed of the stems.

[0091] The specific implementation process is as follows: When the device is in normal working condition, the stems inside the box 3 are slightly lifted and redistributed due to vibration. Guided by the funnel-shaped box 3, the upper and middle layer of stems gradually slides to the bottom along the inclined surface of the inner wall. However, due to the gradual contraction of the funnel-shaped structure, the upper and middle layer of stems are supported by the inclined surface of the box 3, avoiding the situation of concentrated pressure on the bottom stems, and significantly reducing the pressure on the bottom stems. At the same time, the protrusions 21 set on the inner wall of the box 3 have a blocking and dispersing effect on the stems during vibration. When the upper layer of stems is lifted by vibration, its movement trajectory is intermittently blocked by the protrusions 21, and the descent speed is effectively slowed down, so that the stems do not instantly accumulate to the bottom, thus forming a layered and slow-release falling process. This structural design realizes the synergistic effect of vibration, guidance and buffering, so that the stems inside the box 3 can maintain a loose flow state during vibration, and the bottom stems can be smoothly discharged through the discharge pipe 4, avoiding blockage. Through the improvement and coordination of the above structure, this embodiment not only effectively reduces the frequency of manual clearing, but also optimizes the falling path and speed distribution of the stems and tubers through the combined action of the funnel-shaped box 3 and the convex strip 21, significantly improving the continuity of sowing and the overall operation efficiency.

[0092] Example 3:

[0093] As attached Figure 5 As shown, the difference from the above embodiment lies in the following steps in the cultivation method of Polygonatum odoratum under forest cover:

[0094] Step 1, Preparation of Polygonatum multiflorum rhizome tubers: Select 1-2 year old rhizomes that are free from pests and diseases and have plump buds, and cut them into pieces with roots using a tool;

[0095] Step 2, disinfection of the cut surface of the rhizome tuber: disinfect the cut surface and let it air dry;

[0096] Step 3: Turn over and fertilize the land. Before planting, turn over the land, remove weeds and stones, and spread farmyard manure and superphosphate to fertilize the land.

[0097] Step 4, land preparation, furrowing and sowing: Load the rhizome tubers into the box 3, start the engine 13, drive the chassis 1 forward on the land, and then the plow blade 15 opens the sowing furrow on the land. The fertilizer in the feed box 20 is scattered into the sowing furrow. At the same time, the rhizome tubers in the box 3 enter the sowing furrow through the discharge pipe 4.

[0098] Step 5, Covering with soil and management: Cover the sowing furrow with soil, and regularly water and fertilize the germinating and growing Polygonatum cyrtonema.

[0099] Step 6, Cold Protection Management: After planting, cover the soil above the Polygonatum multiflorum planting area with straw or well-rotted manure to protect the Polygonatum multiflorum from the cold and retain moisture.

[0100] Step 7, Pest and Disease Control: During the growing season of Polygonatum multiflorum, spray Bordeaux mixture and trichlorfon to control pests and diseases.

[0101] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
