Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of codonopsis root seedling, and particularly relates to an automatic separating device for codonopsis root seedling. BACKGROUND

[0002] Codonopsis root is a traditional precious Chinese medicinal material, which has the effects of tonifying middle energizer and replenishing qi and tonifying spleen and stomach. Codonopsis root is mainly planted by using the method of 'direct seeding + transplanting'. The cultivated codonopsis root seedlings are usually bundled for convenient transportation and transplanting. The transplanting process mainly includes five steps of ditching, seedling throwing, transplanting, soil covering and film covering. Except for the seedling throwing step, the other steps are basically automated. The specific process is as follows: a seedling groove is opened by a ditching device, the bundled codonopsis root seedlings are separated by workers and placed on a conveying device, the seedlings are conveyed to a transplanting device by the conveying device, the seedlings are automatically transplanted to the seedling groove by the transplanting device, and then the soil covering and film covering are performed to complete the transplanting.

[0003] Usually, a set of codonopsis root seedling transplanting equipment is provided with multiple sets of conveying devices and transplanting devices, generally 4-6 sets, which can simultaneously transplant multiple rows of seedlings. Multiple workers are required to assist in seedling throwing. The process is as follows: the bundled codonopsis root seedlings to be transplanted are first moved and placed on the transplanting equipment, and each worker is responsible for seedling throwing of one or two sets of conveying devices. When the transplanting equipment starts, the bundled codonopsis root seedlings are separated into single plants by the workers and placed on the conveying devices at equal intervals. Finally, the codonopsis root seedlings are uniformly conveyed to the transplanting device by the conveying device for transplanting. The quality of manual seedling throwing is easily disturbed by human factors. Because the seedling throwing speeds of different workers are different, the plant spacing of the seedlings cannot be guaranteed to be uniform, the standardized planting cannot be achieved, and the actual needs of codonopsis root planting cannot be met.

Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0024] In some embodiments, see Figure 1 、 Figure 2 、 Figure 4 or Figure 9 , a device for automatically separating codonopsis pilosula seedlings, comprising: The base frame 1 is welded from square steel pipes to form an L-shaped structure. A first hinge seat 11 and a second hinge seat 12 are respectively provided on the base frame 1.

[0025] The base frame 3 is adjustably mounted on the base frame 1, so that the tilt angle of the base frame 3 can be adjusted, which facilitates the separation of the Codonopsis pilosula seedlings in conjunction with the automatic separation mechanism 4. Specifically, a telescopic rod 2 is hingedly connected to the first hinge seat 11. One side of the base frame 3 is hingedly connected to the telescopic rod 2, and the other side is hingedly connected to the base frame 1. By controlling the extension of the telescopic rod, the base frame 3 can be rotated about the second hinge seat 12, thereby changing the tilt angle of the base frame 3. The telescopic rod 2 can be a hydraulic rod or an electric telescopic rod. The specific structure and control method of the telescopic rod 2 are all existing technologies and are not described in detail here.

[0026] The automatic separation mechanism 4 includes a conveying assembly 41 and a separation assembly 42. The conveying assembly 41 includes a first belt 414, which is rotatably mounted on the base frame 3. The separation assembly 42 includes a second belt 426, which is rotatably mounted on the base frame 3 and located above the first belt 414. A gap is left between the first belt 414 and the second belt 426 to facilitate the passage of the Codonopsis pilosula seedlings. The adjacent belt surfaces of the first belt 414 and the second belt 426 are parallel to each other and move in opposite directions. In addition, first protrusions 4141 are evenly spaced on the first belt 414, and grooves that can only accommodate a single Codonopsis pilosula seedling are formed between adjacent first protrusions 4141. Second protrusions 4261 are arranged uniformly on the second belt 426, and the sum of the heights of the first protrusions 4141 and the second protrusions 4261 is equal to the width of the gap.

[0027] The specific working process is: install the device at a suitable position on the transplanter, adjust the inclination of the base frame 3 through the telescopic rod 2 to meet the use requirements, and align the discharge end of the device with the transplanting mechanism, and arrange 1-2 workers to board the transplanter to assist in adding seedlings. When transplanting begins, workers unbundle the bundled Codonopsis pilosula seedlings and place the unbundled Codonopsis pilosula seedlings on the feed end of the automatic separation mechanism 4, that is, the funnel-shaped structure formed by the first belt 414 and the second belt 426. The Codonopsis pilosula seedlings slide into the grooves on the first belt 414 under the action of gravity for seeding; the Codonopsis pilosula seedlings in the grooves follow the first belt 414 to move to the discharge end. Under the action of the reverse movement of the second belt 426, the Codonopsis pilosula seedlings not in the grooves will be cleaned out of the grooves and returned to the feed end to wait for seeding, so that there is only one Codonopsis pilosula seedling in each groove, thereby realizing automatic separation of the bundled Codonopsis pilosula seedlings. Workers only need to place the unbundled Codonopsis pilosula seedlings at the feed end of the first belt 414. There is no need for workers to place the seedlings, reducing the number of workers required to place the seedlings, and by equidistantly arranged grooves, the intervals between adjacent Codonopsis pilosula seedlings can be guaranteed to be consistent, thereby ensuring the uniform spacing of the seedlings for transplanting, achieving standardized planting, and improving the quality of Codonopsis pilosula transplanting. Furthermore, since the average diameters of Codonopsis pilosula seedlings for transplanting vary in different regions, if the average diameters of the Codonopsis pilosula seedlings are relatively small, their own weight is relatively light and they are not easy to gather at the closing part of the funnel-shaped structure, thus affecting the efficiency of seedling filling. At this time, the base frame 3 can be adjusted to be steeper through the telescopic rod 2, so that the Codonopsis pilosula seedlings can be gathered at the closing part with the help of gravity, making it easier to fill the seedlings.

[0028] It should be noted that due to the varying soil quality in different regions, the criteria for determining the size of Codonopsis pilosula seedlings for transplanting vary. The size of the groove can be adjusted according to actual needs, as long as it can only accommodate a single Codonopsis pilosula seedling. Generally speaking, the size of Codonopsis pilosula seedlings for transplanting is: seedling length between 15–20 cm, and taproot diameter between 0.4-0.6 cm. Taking into account the irregular shape of Codonopsis pilosula seedlings, the width of the groove is 0.5-1 mm larger than the taproot diameter, and the depth of the groove is equal to the average taproot diameter of the Codonopsis pilosula seedling.

[0029] In some embodiments, see Figure 1 、 Figure 9 To facilitate the smooth sliding of the Codonopsis pilosula seedlings into the grooves under the action of gravity, the first protrusion 4141 can be designed as a semicircular structure, thereby expanding the opening of the groove and facilitating the sliding of the Codonopsis pilosula seedlings. In addition, to prevent the second belt 426 from scratching the Codonopsis pilosula seedlings stacked in the grooves when cleaning them, the second protrusion 4261 can also be designed as a semicircular structure. Furthermore, the cross-sectional dimensions of the first protrusion 4141 are larger than the cross-sectional dimensions of the second protrusion 4261. The difference in cross-sectional dimensions between the two can be adaptively adjusted according to actual needs. Since a gap is formed between adjacent second protrusions 4261, generally speaking, the depth of this gap is half the average diameter of the transplanted Codonopsis pilosula seedlings, making it impossible to accommodate the Codonopsis pilosula seedlings. Since some fibrous roots grow around the main roots of the Codonopsis seedlings, these fibrous roots will be entangled with each other when the Codonopsis seedlings are bundled. However, since they are in the seedling stage, these fibrous roots are thin and weak and can be separated by applying a slight external force. The second belt 426 drives the second protrusion 4261 to move in the opposite direction of the Codonopsis seedlings, which can apply a reverse pulling force to the Codonopsis seedlings overlapping in the same groove, thereby breaking the fibrous roots, improving the seedling cleaning effect, and ensuring that there is only one Codonopsis seedling in the same groove.

[0030] In some embodiments, in order to ensure that the Codonopsis pilosula seedlings slide smoothly into the grooves under the action of gravity, the first belt 414 needs to be controlled to rotate at a low speed. Generally speaking, the belt speed of the first belt 414 is preferably between 7.5 mm / s and 10 mm / s. If the belt speed of the first belt 414 is too fast, it is easy to cause the Codonopsis pilosula seedlings to fail to evenly fill each groove, resulting in interruptions in the seedling delivery process, resulting in seedling vacancies in subsequent transplanting. At this belt speed, the seedling delivery efficiency can be guaranteed, and the lack of seedlings in individual grooves can be avoided. In order to ensure the effect of clearing excess Codonopsis seedlings, the second belt 426 needs to be controlled to rotate at a high speed. The belt speed of the second belt 426 is between 110mm / s and 130mm / s. If the second belt 426 rotates too slowly, it is difficult to quickly clear the seedlings; if the second belt 426 rotates too fast, the Codonopsis seedlings are easily skewed due to collision when they come into contact with it, resulting in the seedlings being unable to fall into the groove when lying between the adjacent first protrusions 4141, affecting normal seed filling.

[0031] In some embodiments, see Figure 2 The base frame 3 includes a first base plate 31, a connecting rod 32, and a second base plate 33. The first base plate 31 and the second base plate 33 are both square and symmetrically arranged. The connecting rod 32 secures the first base plate 31 and the second base plate 33 together. The connecting rod 32 is provided with a threaded stud at each end. The threaded stud passes through the first base plate 31 and the second base plate 33, respectively, and is then secured with a nut, thereby forming a double-layer structure for the base frame 3. This secure connection allows for quick and easy separation of the first base plate 31 and the second base plate 33 by removing the nut when maintenance is required.

[0032] In some embodiments, see Figure 5 The conveying assembly 41 also includes a first active roller 411 and a first driven roller 412. The first active roller 411 and the first driven roller 412 are both rotatably mounted on the base frame 3, and a first belt 414 is installed between the first active roller 411 and the first driven roller 412. The first active roller 411 can be driven to rotate by the first motor 44. Furthermore, a first tensioning roller 413 for tensioning the first belt 414 is also rotatably mounted on the base frame 3. Furthermore, since the first belt 414 will be deformed due to the influence of gravity or pressure, in this case, the gap between the first belt 414 and the second belt 426 will become wider, which will cause multiple Codonopsis seedlings to be accommodated in the same groove, affecting the normal progress of subsequent transplanting. Therefore, a support plate 43 is fixedly installed on the second base plate 33 by bolts and nuts. For details, see Figure 2 、 Figure 4 The first belt 414 is divided into an upper side and a lower side, wherein the side close to the second belt 426 is the upper side. A support plate 43 is provided between the upper side and the lower side of the first belt 414. The top surface of the support plate 43 contacts the back surface of the first belt 414. The support plate 43 can support the first belt 414 on the upper side to prevent it from deformation.

[0033] See also Figure 3 、 Figure 8The first active roller 411 includes a transmission shaft 4111, a seat bearing 4112, a sleeve 4113, an active roller 4114, a fixing bolt 4115, and a fixing plate 4116. The seat bearing 4112 is fixedly installed on the first base plate 31 and the second base plate 33. The transmission shaft 4111 is rotatably installed on the seat bearing 4112, and one side of the transmission shaft 4111 is sequentially installed with a sleeve 4113, an active roller 4114 and a fixing plate 4116. The fixing bolt 4115 passes through the fixing plate 4116 and is threadedly connected to the transmission shaft 4111, thereby pressing the sleeve 4113 and fixing it; the other side of the transmission shaft 4111 is connected to the output shaft of the first motor 44 through a coupling 442. The first motor 44 is fixedly connected to the first base plate 31 through a first bracket 441. The transmission shaft 4111 can be driven to rotate by the first motor 44, thereby driving the active roller 4114 to rotate synchronously, driving the first belt 414 to run. It should be noted that the structure and control method of the first motor 44 are both existing technologies and will not be described in detail here.

[0034] See also Figure 3 、 Figure 7 The first driven roller 412 includes a cantilever shaft 4121, a driven roller 4122, a first pressing plate 4123, a second pressing plate 4124, a third pressing plate 4125, and a fourth pressing plate 4126. The fixed end of the cantilever shaft 4121 is provided with an external thread, and the cantilever shaft 4121 is sleeved with the first pressing plate 4123 and the second pressing plate 4124 corresponding to the first substrate 31, and the third pressing plate 4125 and the fourth pressing plate 4126 corresponding to the second substrate 33. The cantilever shaft 4121 is also threadedly connected with nuts corresponding to each pressing plate. By tightening the nuts, the first pressing plate 4123 and the second pressing plate 4124 clamp the first substrate 31, and the third pressing plate 4125 and the fourth pressing plate 4126 clamp the second substrate 33, thereby fixing the cantilever shaft 4121. A driven roller 4122 is rotatably mounted on the suspended end of the cantilever shaft 4121 via a bearing. The driven roller 4122 is in contact with the first belt 414 .

[0035] It should be noted that the structure and installation method of the first tensioning roller 413 are consistent with those of the first driven roller 412 , and the only difference is the installation position, so they will not be described in detail.

[0036] In some embodiments, see Figure 6The separation assembly 42 also includes a second active roller 421, a second driven roller 424, and a third driven roller 425. The second active roller 421, the second driven roller 424, and the third driven roller 425 are all rotatably mounted on the base frame 3, and a second belt 426 is installed between the three. The second active roller 421 can be driven to rotate by the second motor 45. It should be noted that the structure and installation method of the second active roller 421 are exactly the same as those of the first active roller 411; the structure and installation method of the second driven roller 424 and the third driven roller 425 are exactly the same as those of the first driven roller 412. The only difference is the installation position, so they will not be described in detail. The second motor 45 is fixedly mounted on the first base plate 31 through the second bracket 451. The second belt 426 can be driven to rotate by the second motor 45. The structure and control method of the second motor 45 are both existing technologies and will not be described in detail here.

[0037] In some embodiments, see Figure 2 、 Figure 5 The base plate 3 is provided with a first adjustment slot 34 arranged vertically and a second adjustment slot 35 arranged horizontally. A second tensioning roller 422 for tensioning the second belt 426 is adjustably installed at the first adjustment slot 34. An adjustment roller 423 is adjustably installed at the second adjustment slot 35. By installing the adjustment roller 423, the second belt 426 can form an inclined surface at the feeding end, thereby forming a funnel-shaped structure with the first belt 414 to facilitate feeding. Figure 5 For example, the further to the right the adjusting roller 423 is moved, the smaller the opening of the funnel-shaped structure becomes. In this case, the second tensioning roller 422 needs to be moved upward to tighten the second belt 426. Conversely, the further to the left the adjusting roller 423 is moved, the larger the opening of the funnel-shaped structure becomes. In this case, the second tensioning roller 422 needs to be moved downward to tighten the second belt 426. Because the number of single bundles of Codonopsis pilosula seedlings varies from region to region, some regions require a larger number of single bundles of Codonopsis pilosula seedlings, while others require a smaller number of single bundles of Codonopsis pilosula seedlings. By adjusting the size of the opening of the funnel-shaped structure, various single bundles of Codonopsis pilosula seedlings can be accommodated. It should be noted that the structure of the second tensioning roller 422 and the adjusting roller 423 is identical to that of the first driven roller 412. The only difference is that the second tensioning roller 422 and the adjusting roller 423 are mounted within the adjustment slot and fixed in the same manner as the first driven roller 412. This will not be described in detail here.
