Rhizome type traditional Chinese medicinal material bare root seedling pressing and chain forming transplanting device and application thereof

Abstract

This invention relates to the field of agricultural machinery and equipment technology, specifically to a device for pressing and chaining bare-root seedlings of rhizomatous medicinal herbs into a transplanting chain and its application. This addresses the current problem that the transplanting of bare-root seedlings of rhizomatous medicinal herbs typically involves separating and placing seedlings in the field, while the preparation of seedling strings still requires manual pre-processing. This results in a time-consuming, labor-intensive, inefficient, and poorly controlled plant spacing process during field transplanting. The device uses a lower paper roll covered with a biodegradable adhesive layer, driven by a conveyor belt. An upper paper roll rotates on the other side of the platform. Bare-root seedlings, planted at the required spacing, are bonded to the lower and upper paper rolls according to the baffle scale to form a pressed seedling chain. The chained seedlings are then folded horizontally and placed in a transfer box, thus completing the indoor preparation of the bare-root seedlings into a chain. The chain can then be quickly planted in the field after trenching. This achieves spatial and temporal separation of chain planting, effectively saving manpower in field planting and greatly improving the overall efficiency of bare-root seedling transplanting.

Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, specifically to a device for compressing bare-root seedlings of rhizomes into a chain for transplanting and its application. Background Technology

[0002] The cultivation of rhizome-based Chinese medicinal herbs, including Codonopsis pilosula, Angelica sinensis, Astragalus membranaceus, Scutellaria baicalensis, Platycodon grandiflorus, Glycyrrhiza uralensis, Bupleurum chinense, Salvia miltiorrhiza, and Notopterygium incisum, widely adopts the bare-root seedling transplanting method. The traditional transplanting process requires 2-3 people to work together: one person digs the trench, while others bend over and place the seedlings in the trench at a certain plant spacing, and then cover them with soil and mulch. This transplanting method has the following problems: high labor intensity and low efficiency; the manual placement of seedlings is slow, each person can complete a small area per day and multiple people are needed to work together; seedlings are easily damaged; during the manual handling and placement process, seedlings are easily damaged, affecting the survival rate; poor plant spacing accuracy; manual visual placement results in uneven plant spacing, affecting later growth and yield. Existing transplanters generally rely on manual seedling separation. Although some transplanters have achieved mechanical seedling placement, the seedling separation process still requires manual placement of each seedling into the planter. Although continuous seedling supply has been achieved, the separation and placement of seedlings are still completed continuously in the field, and the sorting of seedlings still requires manual pre-operation. Ultimately, this makes the field transplanting process of bare-root seedlings time-consuming, labor-intensive, inefficient, and with poor plant spacing accuracy. Summary of the Invention

[0003] This invention provides a device for compressing bare-root seedlings of rhizomes into a chain for transplanting and its application, in order to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A device for compressing and transplanting bare-root seedlings of rhizomes into a chain includes a platform with a conveyor belt at the top. A meter is attached to the conveyor belt. A lower paper roll is rotatably and detachably mounted on one side of the platform above the conveyor belt. The lower paper strip on the lower paper roll is driven to move in the same direction by the conveyor belt. An upper paper roll is rotatably and detachably mounted on the other side of the platform above the conveyor belt. The upper paper strip on the upper paper roll is also driven to move in the same direction by the conveyor belt. The bonding surface of the lower paper strip is covered with a biodegradable adhesive. The bare-root seedlings and the bonded lower and upper paper strips constitute a compressed seedling chain. A turnover box is movably mounted at the bottom of the platform, and the compressed seedling chain is horizontally folded and placed in the turnover box.

[0005] The turnover box can be detachably placed inside the turnover box bracket of the tractor body. The turnover box bracket is set at the rear of the trencher of the tractor body. A guide arc plate is horizontally and movably connected to the top of the outer side of the turnover box bracket. A movable pressure roller is provided below the guide arc plate and on the side wall of the turnover box bracket. The pressing seedling chain is pressed between the movable pressure roller and the guide arc plate.

[0006] The transplanting unit, which is constructed from the turnover box bracket, guide arc plate, and movable pressure roller, is moved by the pulling force generated by the forward movement of the tractor body. The pressed seedling chain is released sequentially by the relative displacement force generated by the forward movement of the tractor body and is guided by the guide arc plate to fall into the planting ditch in sequence.

[0007] Furthermore, a first upright is symmetrically provided on one side of the platform located above the conveyor belt, and a first mounting shaft is provided between the first uprights, with the lower paper roll rotatably connected to the first mounting shaft.

[0008] Furthermore, a second upright is fixedly and symmetrically provided on the side of the first upright along the direction of travel of the conveyor belt, and a second mounting shaft is provided between the second uprights. A lower paper guide wheel is rotatably provided on the second mounting shaft, and the lower paper belt and the first mounting shaft are pressed clockwise, while the lower paper belt and the lower paper guide wheel are pressed counterclockwise.

[0009] Furthermore, a third upright is symmetrically provided on the other side of the platform above the conveyor belt, and the third upright is provided with a third mounting shaft, and the upper paper roll and the third mounting shaft are rotatably connected.

[0010] Furthermore, a fourth upright is fixedly and symmetrically arranged on the side of the third upright along the direction of travel of the conveyor belt. A fourth mounting shaft is arranged between the fourth uprights. An upper paper guide wheel is rotatably arranged on the fourth mounting shaft. The upper paper belt and the third mounting shaft are pressed clockwise, and the upper paper belt and the upper paper guide wheel are pressed counterclockwise. A third mounting rod is fixedly and horizontally arranged on the side of the fourth upright, and the meter counter is fixedly connected to the third mounting rod.

[0011] Furthermore, the bottom of the platform is fixedly provided with multiple support legs, and a bracket is fixedly provided on the side of the support leg located below the upper paper guide wheel. The turnover box is detachably mounted on the bracket.

[0012] Furthermore, a seedling head baffle is fixedly installed horizontally on the top of the platform, and the seedling head baffle is also provided with a scale.

[0013] Furthermore, a slide rail is fixedly provided on the side of the turnover box hanger, and the side of the guide arc plate is slidably disposed in the slide rail. A fastening screw is also provided through the side wall of the slide rail, and the fastening screw and the side of the guide arc plate are closely attached to each other.

[0014] Furthermore, the transplanting units, which include the turnover box, turnover box bracket, guide arc plate, movable pressure roller, slide rail and fastening screw, are connected in parallel on the planting machine to form a multi-row transplanting machine. Each unit module is equipped with a soil cover and the furrow opener, and is driven by the synchronous drive shaft and electronic controller of the multi-row transplanting machine.

[0015] It also includes the application of a device for compressing bare-root seedlings of rhizomes into a chain for transplanting, comprising the following steps: 1) First, install all the components of the device properly. Then, select the appropriate width of the lower and upper paper tapes, which are pre-coated with biodegradable adhesive, according to the different types of bare-root seedlings of rhizomes and medicinal herbs. Then, start the conveyor belt, and the lower and upper paper tapes will move forward with the conveyor belt.

[0016] 2) Afterwards, the operators, according to the fixed plant spacing required for crop planting, align the heads of the bare-root seedlings with the seedling head baffles using a scale measurement and place them horizontally on the lower paper strip. The bare-root seedlings then move with the lower paper strip to the upper paper guide wheel, which then presses the lower and upper paper strips together, bonding and fixing the bare-root seedlings between the lower and upper paper strips to form a pressed seedling chain. The two ends of the bare-root seedlings are exposed. At the same time, the operators can accurately determine the continuous preparation length of the pressed seedling chain by counting with a meter counter according to the length of the planting plot required for the bare-root seedlings of root and rhizome medicinal herbs, ensuring that the pressed seedling chain of single-row planted crops completely covers the length of the plot.

[0017] 3) Afterwards, the pressed seedling chains are assisted by the operators to be stacked horizontally in a zigzag pattern and placed into the turnover box for later use.

[0018] 4) Next, place the turnover box filled with pressed seedling chains into the turnover box rack of the tractor body. Then, start the tractor body and move forward. The furrow opener opens the first planting furrow. Afterward, the pressed seedling chains are guided by the guide arc plate and fall smoothly and naturally into the planting furrow. At the same time, the sponge movable pressure roller gently presses the pressed seedling chains to ensure good contact with the soil. The planting operator can move the pressed seedling chains on the surface of the furrow left and right by moving the guide arc plate according to the depth of the planting furrow. When the planting furrow is deep, the guide arc plate moves the pressed seedling chains to the right side of the planting direction and secures them with the fastening screw. When the planting furrow is shallow, the guide arc plate moves the pressed seedling chains to the left side of the planting direction and secures them with the fastening screw. This ensures that the planting depth of the pressed seedling chains matches the planting furrow well and ensures the horticultural level of the crop.

[0019] 5) After the first row of planting is completed, replace the new pressed seedling chain and turnover box, and carry out the second row of trenching. The soil turned up by the trenching machine will naturally cover the first row of planting trenches, thus completing the planting and soil covering operation.

[0020] Furthermore, the lower and upper paper guide rollers are made of Teflon PTFE material, with a smooth, groove-free surface. They maintain a preset gap with the conveyor belt and rotate passively using the friction of the paper belt. The self-lubricating properties of PTFE ensure that the biodegradable adhesive does not adhere, and no cleaning is required during long-term operation.

[0021] Furthermore, the conveyor belt is driven by a DC speed-regulating motor, a PVC or rubber belt, and features stepless speed regulation.

[0022] The present invention has the following beneficial effects: This invention provides a device for compressing and transplanting bare-root seedlings of rhizomes into a chain and its application. A lower paper roll rotates on one side of a platform above a conveyor belt. A lower paper strip covered with a biodegradable adhesive is driven to move in the same direction by the conveyor belt. The conveyor belt drives the lower paper strip, lower paper roll, upper paper strip, and upper paper roll to rotate synchronously. Operators place the bare-root seedlings according to the required planting spacing, using dimensional control, and then bond them to the lower and upper paper strips to form a compressed seedling chain. The bare-root seedlings are held at the waist with both ends exposed, and are then horizontally folded with zero tension and placed in a transfer box, preventing the bare-root seedlings from being pulled apart. Even with tearing damage, the process allows for the rapid indoor preparation of bare-root seedlings of rhizomatous medicinal herbs into chains, which can then be quickly and tension-freely planted in the field after trenching. This achieves spatial and temporal separation for the chain planting of bare-root seedlings of rhizomatous medicinal herbs, and is not limited by weather conditions. It effectively saves human resources in field planting and greatly improves the overall transplanting efficiency of bare-root seedlings of rhizomatous medicinal herbs. It solves the problem that in the current process of transplanting bare-root seedlings of rhizomatous medicinal herbs, the seedling separation and placement are generally completed in the field, and the seedlings still need to be pre-processed manually. This results in a time-consuming, labor-intensive, inefficient, and poorly controlled plant spacing process in the field transplanting of bare-root seedlings.

[0023] This invention achieves the separation of time and space between the division and planting of bare-root seedlings of rhizomatous Chinese medicinal materials, allowing the division process to be completed indoors in advance. Only one or two people are needed to operate the mechanical planting operation in the field, which reduces equipment costs and makes it easy for farmers to adopt. It is applicable to various types of bare-root seedling crops of long rhizomatous Chinese medicinal materials and has wide applicability.

[0024] The meter counter in this invention enables operators to accurately determine the continuous preparation length of the pressed seedling chain based on the required planting plot length for root and rhizome medicinal crops during the pressing seedling chain preparation process. This ensures that the pressed seedling chain for single-row planting completely covers the plot length and is then folded and placed in a turnover box for later use. This effectively ensures the continuity of single-row planting and avoids the need to stop and replace the pressed seedling chain midway through the single-row planting process, thereby greatly improving the overall efficiency of root and rhizome medicinal herb planting.

[0025] The guide arc plate in this invention is designed to slide left and right and be secured in real time. This allows planting workers to move the pressed seedling chain on its surface left and right according to the depth of the planting trench. When the planting trench is deep, the guide arc plate moves the pressed seedling chain to the right side of the planting direction and secures it with a fastening screw. When the planting trench is shallow, the guide arc plate moves the pressed seedling chain to the left side of the planting direction and secures it with a fastening screw. This ensures that the planting depth of the pressed seedling chain matches the planting trench well, thereby effectively improving the horticultural level of root and tuber medicinal crops.

A turnover box 24 is movably provided at the bottom of the platform 1, and the compressed seedling chain 23 is horizontally folded and placed in the turnover box 24.

[0031] The turnover box 24 can be detachably placed inside the turnover box bracket 29 of the tractor body 25. The turnover box bracket 29 is located at the rear of the furrow opener 27 of the tractor body 25. A guide arc plate 30 is horizontally and movably connected to the top of the outer side of the turnover box bracket 29. A movable pressure roller 32 is provided below the guide arc plate 30 and on the side wall of the turnover box bracket 29. The pressing chain 23 is pressed between the movable pressure roller 32 and the guide arc plate 30.

[0032] The transplanting unit, which is constructed by the turnover box bracket 29, the guide arc plate 30 and the movable pressure roller 32, is pulled and displaced by the pulling force generated by the forward movement of the tractor body 25. The pressed seedling chain 23 is released sequentially by the relative displacement force generated by the forward movement of the tractor body 25 and is guided by the guide arc plate 30 to fall into the planting trench 33.

[0033] A first upright 3 is symmetrically arranged on one side of the platform 1 above the conveyor belt 21, and a first mounting shaft 4 is arranged between the first uprights 3. The lower paper roll 5 is rotatably connected to the first mounting shaft 4.

The upper paper tape 16 and the third mounting shaft 11 are pressed clockwise, and the upper paper tape 16 and the upper paper guide wheel 15 are pressed counterclockwise. A third mounting rod 35 is fixedly and horizontally provided on the side of the fourth upright 13. The meter counter 36 is fixedly connected to the third mounting rod 35.

[0037] The bottom of the platform 1 is fixedly provided with four support legs 2. The support legs 2 located below the upper paper guide wheel 15 are fixedly provided with a bracket 22. The turnover box 24 is detachably mounted on the bracket 22.

[0038] A seedling baffle 17 is fixed horizontally on the top of platform 1, and a scale 18 is also provided on the seedling baffle 17.

[0039] The side of the turnover box hanger 29 is fixedly provided with a slide rail 37, the side of the guide arc plate 30 is slidably disposed in the slide rail 37, and a fastening screw 38 is also provided through the side wall of the slide rail 37, and the fastening screw 38 and the side of the guide arc plate 30 are closely attached.

[0040] The transplanting units, consisting of turnover box 24, turnover box bracket 29, guide arc plate 30, movable pressure roller 32, slide rail 37 and fastening screw 38, are connected in parallel on the planting machine to form a multi-row transplanter. Each unit module is equipped with a soil cover and the aforementioned furrow opener 27, and is driven by the synchronous transmission shaft and electronic controller of the multi-row transplanter.

[0041] The inlet width of the guide arc plate 30 is slightly larger than the width of the turnover box 24, and it is close to the seedling outlet of the turnover box 24. The surface is smooth and it is located behind the furrow opener 27.

[0042] The movable pressure roller 32 is a medium-density sponge roller, slightly wider than the pressing seedling chain 23, and is spring-loaded with adjustable pressure. It is used to lightly press the pressing seedling chain 23 to make it in close contact with the soil 34.

[0043] Furthermore, a turnover box bracket 29 is fixedly welded to the crossbeam 26 of the tractor body 25 via a first mounting rod 28. A guide arc plate 30 is connected to the outlet of the turnover box bracket 29. A turnover box 24 filled with a pressed seedling chain 23 is placed inside the turnover box bracket 29. A movable pressure roller 32 is also connected to the side of the turnover box bracket 29 via a second mounting rod 31 and a spring. The pressed seedling chain 23 and the movable pressure roller 32 are pressed clockwise.

[0044] Furthermore, both the lower and upper paper tapes are made of biodegradable paper tape, such as biodegradable kraft paper. The biodegradable adhesive is starch glue, which can decompose naturally in the soil. The meter counter is a rubber wheel Z96-F model meter counter.

[0045] In practical applications, the compression chain formation process is as follows: Figure 1 As shown, first, all components of the device are properly installed. Then, according to the different types of bare-root seedlings of rhizomatous medicinal herbs, a lower paper strip 9 and an upper paper strip 16, pre-coated with biodegradable adhesive 19, are selected with matching widths. The drive motor of the conveyor belt 21 is then started, causing the lower paper strip 9 and upper paper strip 16 to move forward with the conveyor belt 21. At this time, the lower paper roll 5, upper paper roll 12, lower paper guide wheel 8, and upper paper guide wheel 15 all rotate passively. Then, according to the fixed plant spacing required for crop planting, the operator, through measurement using the scale 18, aligns the head of the bare-root seedling 20 with the seedling head baffle 17 and places it horizontally on the lower paper strip 9. The bare-root seedling 20 then moves with the lower paper strip 9. Paper tape 9 moves to the upper paper guide wheel 15, which presses the lower paper tape 9 and the upper paper tape 16 together, thus bonding and fixing the bare-root seedlings 20 between the lower paper tape 9 and the upper paper tape 16 to form a pressed seedling chain 23. The ends of the bare-root seedlings 20 are exposed. The pressed seedling chain 23 is then assisted by the operator to be horizontally stacked in a zigzag pattern and placed into the turnover box 24. Simultaneously, the operator can accurately determine the continuous length of the pressed seedling chain 23 based on the length of the planting plot required for root and rhizome medicinal herbs using a meter counter 36, ensuring that the pressed seedling chain 23 completely covers the length of the plot for single-row planting. The chain is then folded and placed in the turnover box 24 for later use. Furthermore, for different root and rhizome medicinal herbs, only the width of the lower paper tape 9 and the upper paper tape 16, as well as the plant spacing, need to be adjusted to complete the pressing of the bare-root seedlings into a chain.

[0046] Single-row planting process in the field: such as Figure 2 As shown, a turnover box 24 filled with pressed seedling chains 23 is placed in the turnover box bracket 29 of the tractor body 25. Then, the tractor body 25 starts moving forward, and the furrow opener 27 opens the first planting furrow 33. Afterward, the pressed seedling chains 23 are guided by the guide arc plate 30 and fall smoothly and naturally into the planting furrow 33. At the same time, the sponge movable pressure roller 32 gently presses the pressed seedling chains 23 to ensure good contact with the soil 34. Furthermore, the planting operator can adjust the planting furrow 33 in a timely manner by moving the guide. The arc plate 30 moves the pressed seedling chain 23 on its surface left and right. When the planting trench 33 is deep, the guide arc plate 30 moves the pressed seedling chain 23 to the right side of the planting direction and secures it with the fastening screw 38. When the planting trench 33 is shallow, the guide arc plate 30 moves the pressed seedling chain 23 to the left side of the planting direction and secures it with the fastening screw 38. This ensures that the planting depth of the pressed seedling chain 23 matches the planting trench 33 well, improving the horticultural level of root and tuber medicinal crops. Afterward, a new pressed seedling chain 23 and turnover box 24 are replaced, and the second row of trenches is opened. The soil 34 turned up by the trench opener 27 naturally covers the first row of planting trenches 33, thus completing the planting and covering operation.

[0047] Furthermore, the turnover box 24, turnover box bracket 29, guide arc plate 30, second mounting rod 31, movable pressure roller 32, slide rail 37, and fastening screw 38 of this device can also serve as basic transplanting units, according to... Figure 2 The multi-row transplanter is installed in parallel on a large planting machine. It is independently equipped with a furrow opener 27 and a soil coverer. It is driven by the synchronous drive shaft or electronic controller of the multi-row transplanter to complete the rapid multi-row planting of bare-root seedlings of root and rhizome Chinese medicinal crops.

[0048] The entire process of compressing bare-root seedlings of root and rhizome medicinal crops into a chain and planting them in the field is fast and efficient. It achieves the separation of time and space in seedling chain preparation and planting, effectively saves manpower in field planting, and greatly improves the overall transplanting efficiency of bare-root seedlings of root and rhizome medicinal crops.

Then, select the appropriate width of the lower paper tape (9) and upper paper tape (16) pre-coated with biodegradable adhesive (19) according to the different types of bare-root seedlings of rhizomes and medicinal materials. Then, start the conveyor belt (21), and the lower paper tape (9) and upper paper tape (16) will move forward with the conveyor belt (21). 2) Afterwards, the workers, according to the fixed plant spacing required for crop planting, use the scale (18) to measure and align the head of the bare root seedling (20) with the seedling head baffle (17) and place it horizontally on the lower paper strip (9). Then, the bare root seedling (20) moves to the upper paper guide wheel (15) along with the lower paper strip (9). The upper paper guide wheel (15) then presses the lower paper strip (9) and the upper paper strip (16) together, so that the bare root seedling (20) is glued and fixed between the lower paper strip (9) and the upper paper strip (16) to form a pressed seedling chain (23). The two ends of the bare root seedling (20) are exposed. At the same time, the workers can accurately determine the continuous preparation length of the pressed seedling chain (23) according to the length of the planting plot required for the bare root seedlings of rhizomes and medicinal herbs, by counting with a meter counter (36), to ensure that the pressed seedling chain (23) of the single-row crop completely covers the plot length. 3) Afterwards, the pressed seedling chain (23) is assisted by the operator to be stacked horizontally in a "Z" shape and placed into the turnover box (24) for later use; 4) Place the turnover box (24) filled with the pressed seedling chain (23) into the turnover box rack (29) of the tractor body (25). Then, the tractor body (25) starts to move forward, and the furrow opener (27) opens the first planting furrow (33). After that, the pressed seedling chain (23) is guided by the guide arc plate (30) and falls smoothly and naturally into the planting furrow (33). At the same time, the sponge movable pressure roller (32) gently presses the pressed seedling chain (23) to make it in good contact with the soil (34). The planting operator can adjust the planting furrow (33) in time according to the depth of the planting furrow (33). The guide arc plate (30) moves the pressed seedling chain (23) on its surface left and right. When the planting trench (33) is deep, the guide arc plate (30) moves the pressed seedling chain (23) to the right side of the planting direction and is fastened by the fastening screw (38). When the planting trench (33) is shallow, the guide arc plate (30) moves the pressed seedling chain (23) to the left side of the planting direction and is fastened by the fastening screw (38). This ensures that the planting depth of the pressed seedling chain (23) matches the planting trench (33) well and ensures the horticultural level of the crop. 5) After the planting of the first row is completed, replace the new pressed seedling chain (23) and turnover box (24), and carry out the second row of trenching. The soil (34) turned up by the trench opener (27) naturally covers the first row of planting trench (33), thus completing the planting and covering operation.
