Description

Technical Field

[0001] The present invention relates to the technical field of sowing, and in particular to a production system and a production method for automatic lawn sowing. Background Art

[0002] Lawns are increasingly used in people's daily lives, and in order to cultivate good lawns, preliminary preparations need to be made.

[0003] Specifically, lawn cultivation is commonly carried out on a seedbed, but the relevant technology mainly relies on manual means, including covering the soil and sowing on the seedbed, which are all performed manually, thereby reducing the cultivation efficiency. Summary of the Invention

[0004] The technical problem solved by the present invention is that the related art mainly relies on manual means to achieve the preliminary preparation of the lawn, including the operations of covering the soil on the seedbed and sowing, which are all performed manually, resulting in a low degree of automation and thus reducing the cultivation efficiency.

[0005] In order to solve the above problems, the present invention provides a production system for automatic lawn sowing, including: a transmission device, which transports the seedbed provided thereon to a first covering device, a sowing device and a second covering device in sequence; the first covering device is used to perform a first covering action on the seedbed; the sowing device is used to perform a sowing action on the seedbed; and the second covering device is used to perform a second covering action on the seedbed.

[0006] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: specifically, the production system realizes the automated processing of the preliminary preparation work in the process of cultivating lawns, thereby improving the overall production efficiency and saving labor costs; in combination with the actual planting situation, in order to ensure that the growth condition of the seedlings in the seedbed remains good, the seedlings are covered with soil twice in succession. The execution of the first covering action facilitates the stable rooting of the seedlings in the seedbed, and is different from the first covering action. The second covering amount of the second covering action is less than the first covering amount of the first covering action, so as to avoid the seedlings being crushed by the second covering amount. Combined with the humidification treatment of the second covering action, that is, the heavy seedlings in the seedbed are sprayed with a spray device, the execution of the second covering action creates a moist environment for the seedlings, thereby improving the survival rate of the seedlings.

[0007] In one example of the present invention, the first covering device includes: a containing bin, the containing bin is provided with a first feed port and a first discharge port that are relatively arranged; a dividing assembly, the dividing assembly is rotatably connected to the containing bin, and the dividing assembly is provided with a dividing piece extending around its rotation axis; wherein, when the dividing assembly rotates around the rotation axis along a first direction, the discharge spacing formed between the dividing piece and the first discharge port changes continuously.

[0008] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: in combination with the actual soil covering device for the seedbed covering process, the soil-moving action of the common soil-moving equipment is relatively simple, which is specifically manifested in controlling the opening of the movable door provided at the first discharge port, thereby releasing the soil loaded into the storage bin to the seedbed at the corresponding position. However, it is understandable that the soil is easy to condense into lumps during the stacking process, and if it is not broken up, it will be unfavorable for the seedlings to take root when it is transported to the seedbed, and the seedbed cannot be fully covered. In comparison, in the present technical solution, the adjustment of the discharge spacing during the rotation of the material-dividing component is used to place the soil loaded therein in a variable space, effectively reducing the situation where the soil is deposited and clotted in a fixed space, especially the soil in the discharge spacing corresponding to the first discharge port, thereby ensuring that the soil at this position is transported to the seedbed as soon as possible by the rotation of the material-dividing component.

[0009] In one example of the present invention, the material dividing assembly further comprises a rotating shaft, and the material dividing piece is a threaded blade connected to the rotating shaft.

[0010] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: specifically, the structure of the threaded blades is simple, and the rotation of the threaded blades is used to cut the soil at the corresponding position to obtain fine soil. Furthermore, the obtained fine soil is introduced into the seedbed through the first discharge port from the discharge spacing. Combined with the characteristics of the discharge spacing, soil blocks larger than the discharge spacing cannot be discharged smoothly into the seedbed, that is, the discharge spacing has a certain blocking effect on larger soil blocks, preventing them from entering the seedbed and crushing the seedlings therein; in addition, compared with the optical axis, the setting of the threaded blades avoids the situation where the optical axis rotates and the soil cannot be smoothly brought out of the first discharge port.

[0011] In one example of the present invention, the material dividing component includes a first rotating shaft and a second rotating shaft arranged parallel to each other, and the material dividing component includes a first threaded blade and a second threaded blade; the first rotating shaft and the first threaded blade are connected to each other, and the first threaded blade extends around the first axis of the first rotating shaft; the second rotating shaft and the second threaded blade are connected to each other, and the second threaded blade extends around the second axis of the second rotating shaft; wherein a discharge channel is formed between the first threaded blade and the second threaded blade.

[0012] Compared with the existing technology, the technical effects achieved by adopting this technical solution are: for example, the first dividing component and the second dividing component have the same structure, and the simultaneous operation of the first dividing component and the second dividing component improves the covering efficiency of the soil covering device for the seedbed; in addition, the soil covered through the discharge channel between the first dividing component and the second dividing component is cut by the joint cutting action of the two, so that this part of the soil is fully cut and divided.

[0013] In one example of the present invention, the sowing device includes: a feed bin, which is provided with a second feed port and a second discharge port that are relatively arranged; a first combing assembly, which is rotatably connected to the feed bin and is located in the accommodating space of the feed bin; a material guide member, which is arranged in the accommodating space and is located on the side of the first combing assembly close to the second discharge port; wherein, when the target haystack is placed on the material guide slope of the material guide member, the first combing assembly performs a combing action on it to guide it from the material guide slope to the second discharge port.

[0014] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: the sowing device in this technical solution uses the first combing component to perform a combing action on the target grass placed therein, that is, on the seedlings, so that the target grass pile can be roughly evenly separated in the feed bin, reducing the situation where the seedlings clumping together, so that the number of seedlings transported to multiple areas on the seedbed remains even.

[0015] In one example of the present invention, the feed bin includes a mounting surface and a discharge guide surface corresponding to each other and forming a second discharge port, the mounting surface and the discharge guide surface are arranged opposite to each other, and the guide member is arranged on the mounting surface; wherein, the first distance formed between the guide slope and the first combing component is smaller than the second distance formed between the discharge guide surface and the first combing component.

[0016] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: specifically, by adding a material guide member to the installation surface, the height of the seedlings placed thereon is raised by using the material guide member, thereby shortening the distance between the first combing component and the seedlings at that position, that is, making the first distance smaller than the second distance, thereby enabling the first combing component to perform effective combing actions on as many seedlings as possible on the material guide slope, thereby ensuring the number of seedlings discharged from the second discharge port.

[0017] In one embodiment of the present invention, the material guide is movably connected to the feed bin; wherein, when the material guide is adjusted to move in a direction perpendicular to the rotation axis of the first combing component, the size of the first distance is changed.

[0018] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: for example, the material guide is specifically manifested as a plate structure, and the plate structure is screwed to the corresponding inner wall of the feed bin, and the plate structure is provided with a waist-shaped hole extending in the up and down directions. Correspondingly, the inner wall is also provided with a waist-shaped groove adapted thereto, which is fixed at different positions of the medicinal hole by tightening bolts, so as to realize the up and down movement of the material guide in the feed bin, thereby changing the first distance, that is, the size of the first distance.

[0019] In one example of the present invention, the sowing device also includes: a discharge bin, which is arranged at a position of the feed bin corresponding to the second discharge port; a second combing assembly, which is rotatably connected to the discharge bin to form a feed channel between the second discharge port; wherein the feed channel is arranged on one side of the coplanar surface formed by the third axis of the second combing assembly and the fourth axis of the first combing assembly, and the material guide is located on the other side of the coplanar surface.

[0020] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: the discharge bin has a convergent effect on the seedlings introduced from the discharge port, and combined with the setting of the second combing component, it can further ensure the uniform distribution of the seedlings introduced into the seedbed, and by arranging the guide member and the feed channel on both sides of the coplanar surface mentioned above, that is, the feed channel is located below the discharge guide surface, which effectively shortens the path of the seedlings from the sowing device into the seedbed, thereby reducing the loss of seedlings during transportation.

[0021] On the other hand, the present invention also provides a production method for automatic lawn sowing, which is applied to a production system as in any of the above examples; the production method includes: after the transmission device is started, the empty seedbed is transported to the position corresponding to the first soil covering device, and the first soil covering device is controlled to perform a first soil covering action on the empty seedbed to obtain a first seedbed; the first seedbed is transported to the position corresponding to the sowing device, and the sowing device is controlled to perform a sowing action on the first seedbed to sow the target grass pile on the first seedbed to obtain a second seedbed; the second seedbed is transported to the position corresponding to the second soil covering device, and the second soil covering device is controlled to perform a second soil covering action on the second seedbed to obtain a third seedbed; wherein the soil covering thickness corresponding to the first soil covering action is greater than the soil covering thickness corresponding to the second soil covering action.

[0022] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: it can achieve the technical effect corresponding to any of the above technical solutions, which will not be repeated here.

[0023] In one example of the present invention, the production system also includes a water storage device, a film covering device, a spraying device and a soil compacting device; before transporting the empty seedling bed to the position corresponding to the first soil covering device, the production method also includes: transporting the initial seedling bed to the position corresponding to the water storage device by the transmission device; controlling the water storage device to perform a water adding action on the initial seedling bed to obtain a fourth seedling bed; transporting the fourth seedling bed to the position corresponding to the film covering device by the transmission device, controlling the film covering device to cover the fourth seedling bed with a mesh film to obtain an empty seedling bed; and / or, after controlling the soil covering device to perform a second soil covering action on the second seedling bed to obtain a third seedling bed, the production method also includes: transporting the third seedling bed to the position corresponding to the spraying device by the transmission device, controlling the spraying device to perform a spraying action on the third seedling bed to obtain a fifth seedling bed; transporting the fifth seedling bed to the position corresponding to the soil compacting device by the transmission device, controlling the soil compacting device to perform a soil compacting action on the fifth seedling bed to obtain a target seedling bed.

[0024] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: it can achieve the technical effect corresponding to any of the above technical solutions, which will not be repeated here.

[0025] After adopting the technical solution of the present invention, the following technical effects can be achieved:

[0026] (1) Specifically, the production system realizes the automation of the preparatory work in the process of cultivating lawn, thereby improving the overall production efficiency and saving labor costs. In view of the actual planting situation, in order to ensure that the growth condition of the seedlings in the seedbed remains good, the seedlings are covered with soil twice in succession. The execution of the first covering action facilitates the stable rooting of the seedlings in the seedbed. Different from the first covering action, the second covering action has a smaller amount of soil than the first covering action, so as to avoid the seedlings being crushed by the second covering amount. In combination with the humidification treatment of the second covering action, that is, the heavy seedlings in the seedbed are sprayed with a spray device, the execution of the second covering action creates a moist environment for the seedlings, thereby improving the survival rate of the seedlings.

[0027] (2) In combination with the actual soil covering device for the seedling bed, the soil-moving action of common soil-moving equipment is relatively simple, specifically controlling the opening of the movable door provided at the first discharge port, and then releasing the soil loaded into the storage bin onto the seedling bed at the corresponding position. However, it is understandable that the soil tends to condense into lumps during the accumulation process, and if it is not broken up, it will be detrimental to the rooting of the seedlings when it is transported to the seedling bed, and the seedling bed cannot be fully covered. In comparison, in the present technical solution, the adjustment of the discharge spacing during the rotation of the material-dividing component allows the soil loaded therein to be in a variable space, effectively reducing the situation where the soil is deposited and clumps in a fixed space, especially the soil in the discharge spacing corresponding to the first discharge port, thereby ensuring that the soil at that position is transported to the seedling bed as soon as possible by utilizing the rotation of the material-dividing component;

[0028] (3) By adding a material guide, on the one hand, the residual amount of seedlings in the feed bin is reduced, and the effective utilization rate of the seedlings is improved; on the other hand, considering the different actual sowing needs, the seedlings are at different growth stages, and the effective combing distance of the first combing component is limited, the material guide is used to shorten the distance between the seedlings and the first combing component, which to a certain extent meets the needs of seedlings in an earlier growth stage, that is, seedlings with a lower growth height, and can also achieve a good combing effect, thereby improving the transportation of seedlings in more likely growth stages.

DETAILED DESCRIPTION

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0042] Example 1:

[0043] See also Figure 1 , which is a structural diagram of a production system 100 for automatic lawn seeding provided by the first embodiment of the present invention. Figure 2-Figure 9 Specifically, the production system 100 includes, for example, a transmission device 10, a first soil covering device 20, a sowing device 40, and a second soil covering device 30. The first soil covering device 20 is used to perform a first soil covering operation on the seedbed 60; the sowing device 40 is used to perform a sowing operation on the seedbed 60; and the second soil covering device 30 is used to perform a second soil covering operation on the seedbed 60.

[0044] Specifically, the production system 100 realizes the automation of the preliminary preparation work in the process of cultivating lawn, improves the overall production efficiency and saves labor costs; in combination with the actual planting situation, in order to ensure that the growth condition of the seedlings in the seedbed 60 remains good, the seedlings are covered with soil twice in succession. The execution of the first covering action facilitates the stable rooting of the seedlings in the seedbed 60. Different from the first covering action, the second covering amount of the second covering action is less than the first covering amount of the first covering action, so as to avoid the seedlings being crushed by the second covering amount. The humidification treatment of the second covering action is combined, that is, the seedlings in the seedbed 60 are sprayed with a spray device, so that the execution of the second covering action creates a moist environment for the seedlings, thereby improving the survival rate of the seedlings.

[0045] Preferably, the first covering device 20 includes, for example, a receiving bin 21 and a material distribution assembly 22. The receiving bin 21 is provided with a first material inlet and a first material outlet 211 disposed opposite to each other; the material distribution assembly 22 is rotatably connected to the receiving bin 21 and is provided with a material distribution member extending around its rotation axis; wherein, when the material distribution assembly 22 rotates around the rotation axis in a first direction, a material distribution distance 212 formed between the material distribution member and the first material outlet 211 continuously changes.

[0046] In conjunction with the actual soil covering process of the seedbed 60 by the soil covering device, the soil-shoveling action of the common soil-shoveling equipment is relatively simple, specifically controlling the opening of the movable door provided at the first discharge port 211, thereby releasing the soil loaded into the storage chamber 21 onto the seedbed 60 at the corresponding position. However, it is understandable that the soil tends to condense into lumps during the accumulation process. If it is not broken up, it will be detrimental to the rooting of the seedlings when it is transported to the seedbed 60, and it will not be possible to fully cover the seedbed 60. In contrast, in the present technical solution, the adjustment of the discharge spacing 212 during the rotation of the dividing assembly 22 allows the soil loaded therein to be placed in a variable space, effectively reducing the situation where the soil is deposited and clumps in a fixed space, especially the soil in the discharge spacing 212 corresponding to the first discharge port 211, thereby ensuring that the soil at this position is transported to the seedbed 60 as soon as possible by the rotation of the dividing assembly 22.

[0047] Furthermore, the discharge spacing 212 includes a first arrangement spacing, which is composed of a plurality of discharge gaps spaced apart from each other; when the dividing member rotates around the first direction by a first angle, the first arrangement spacing formed at the first position is transferred along the extension direction of the rotation axis toward the second position; and / or, when the dividing member rotates around the first direction by a second angle, the first arrangement spacing formed at the first position is first transferred along the extension direction of the rotation axis toward the second position, and then changed from the second position to the first position.

[0048] Preferably, the material dividing assembly 22 further includes a rotating shaft, and the material dividing piece is a threaded blade connected to the rotating shaft.

[0049] Specifically, the structure of the threaded blades is simple, and the rotation of the threaded blades is used to cut the soil at the corresponding position to obtain fine soil. Furthermore, the obtained fine soil is introduced into the seedbed 60 through the first discharge port 211 from the discharge spacing 212. Combined with the characteristics of the discharge spacing 212, soil blocks larger than the discharge spacing 212 cannot be discharged smoothly into the seedbed 60, that is, the discharge spacing 212 has a certain blocking effect on larger soil blocks, preventing them from entering the seedbed 60 and crushing the seedlings therein; in addition, compared with the optical axis, the setting of the threaded blades avoids the situation where the optical axis rotates and the soil cannot be smoothly brought out of the first discharge port 211.

[0050] Preferably, the material dividing component 22 includes a first rotating shaft 2211 and a second rotating shaft 2221 arranged parallel to each other, and the material dividing part includes a first threaded blade 2212 and a second threaded blade 2222; the first rotating shaft 2211 and the first threaded blade 2212 are connected to each other, and the first threaded blade 2212 extends around the first axis of the first rotating shaft 2211; the second rotating shaft 2221 and the second threaded blade 2222 are connected to each other, and the second threaded blade 2222 extends around the second axis of the second rotating shaft 2221; wherein, a discharge channel is formed between the first threaded blade 2212 and the second threaded blade 2222.

[0051] For example, the first rotating shaft 2211 and the first threaded blade 2212 are combined into the first dividing component 221, and the second rotating shaft 2221 and the second threaded blade 2222 are combined into the second dividing component 222, and the first dividing component 221 and the second dividing component 222 have the same structure. The simultaneous operation of the first dividing component 221 and the second dividing component 222 improves the soil covering efficiency of the seedling bed 60 by the covering device; in addition, the soil covered through the discharge channel between the first dividing component 221 and the second dividing component 222 is cut by the joint cutting action of the two, so that the soil in this part is fully cut and divided.

[0052] In a specific example, at least one of the first threaded blade 2212 and the second threaded blade 2222 includes a first blade segment and a second blade segment that are staggered with each other; wherein the first blade segment and the second blade segment are combined to form a circular projection concentrically arranged with the rotation axis in the axial projection along the rotation axis; and / or, the first thread spacing of the first blade segment along the axial direction of the rotation axis and the second thread spacing of the second blade segment along the axial direction are equal.

[0053] Furthermore, the material-distributing component 22 can be driven by a first drive assembly to achieve the effect of rotating around the rotation axis. The first drive assembly, for example, includes a first drive member and a second drive member, the first drive member being used to drive the first material-distributing component 221 to rotate around a first direction, and the second drive member being used to drive the second material-distributing component 222 to rotate around a second direction opposite to the first direction.

[0054] Preferably, the seeding device 40 includes, for example, a feed bin 41, a first combing assembly 42, and a guide member 43. The feed bin 41 is provided with a second feed inlet 411 and a second discharge outlet 412 that are arranged opposite each other; the first combing assembly 42 is rotatably connected to the feed bin 41 and is located within the storage space of the feed bin 41; the guide member 43 is disposed within the storage space, on a side of the first combing assembly 42 near the second discharge outlet 412. When a target pile of grass is placed on the guide slope 431 of the guide member 43, the first combing assembly 42 combs it, directing it from the guide slope 431 to the second discharge outlet 412.

[0055] In conventional seeding equipment, a movable door is provided at the position corresponding to the second discharge port 412. In conjunction with the entire production line process, when an empty seedbed 60 is transported to the position corresponding to the seeding equipment via the production line's conveying device 10, the movable door is controlled to open, allowing the seedlings placed therein to be transferred to the seedbed 60. Although the above technical means can achieve the purpose of sowing seedlings in the seedbed 60, the seedlings are easily entangled with each other, resulting in the seedlings being transported to the seedbed 60 in a clumping form. This makes it difficult to ensure uniform distribution of the seedlings on the seedbed 60 and to ensure that the density of the seedlings on the seedbed 60 is within a reasonable range, that is, to avoid the situation where the density is too high or too low despite uniform distribution.

[0056] Therefore, in conjunction with this technical solution, unlike the aforementioned sowing equipment, the sowing device 40 of this technical solution uses a first combing assembly 42 to perform a combing action on the target grass material placed therein, that is, the seedlings, so that the target grass pile can be roughly evenly separated in the feed bin 41, reducing the clumping of seedlings and maintaining a uniform number of seedlings transported to multiple areas of the seedbed 60. Simply put, the combing action performed by the first combing assembly 42 can be compared to the technical means of combing hair with a comb.

[0057] Specifically, compared with traditional sowing equipment, in this technical solution, the first combing component 42 provided at the second discharge port 412 is used to stop the seedlings. When the first combing component 42 is stationary, it can prevent the seedlings from falling through the second discharge port 412. In contrast, by controlling the rotation of the first combing component 42, the seedlings are driven from the second discharge port 412 into the seedbed 60.

[0058] In a specific example, the first combing component 42 divides the area of ​​the feed bin 41 corresponding to the second discharge port 412 into a transition area 413 and a discharge area 414. Specifically, the transition area 413 and the discharge area 414 are symmetrically arranged about the axis around which the first combing component 42 rotates, and the forward rotation of the first combing component 42 around the axis is defined as the feeding direction. Therefore, after the operator places the seedlings in the transition area 413 corresponding to the feed bin 41, the first combing component 42 is controlled to rotate forward. Then, the first combing component 42 performs a combing action on the seedlings accumulated in the filter area, thereby driving the seedlings that are in contact with the first combing component 42 or within a suitable distance from the transition area 413 to the discharge area 414, and then escapes from the second discharge port 412 and finally enters the seedbed 60.

[0059] Furthermore, in order to reduce the residual amount of seedlings in the transition area 413 , a guide member 43 is added to this area to ensure that as many seedlings as possible can be guided into the discharge area 414 .

[0060] Preferably, the feed bin 41 includes a mounting surface and a discharge guide surface 415 correspondingly arranged to form the second discharge port 412. The mounting surface and the discharge guide surface 415 are arranged opposite each other, and the guide member 43 is provided on the mounting surface. A first distance formed between the guide slope 431 and the first combing assembly 42 is smaller than a second distance formed between the discharge guide surface 415 and the first combing assembly 42. Specifically, by adding the guide member 43 to the mounting surface, the height of the seedlings placed thereon is raised by the guide member 43, thereby reducing the distance between the first combing assembly 42 and the seedlings at that position, i.e., making the first distance smaller than the second distance. This enables the first combing assembly 42 to effectively comb as many seedlings as possible on the guide slope 431, thereby ensuring the number of seedlings discharged from the second discharge port 412.

[0061] Furthermore, by adding the guide member 43, on the one hand, the residual amount of seedlings in the feed bin 41 is reduced, thereby improving the effective utilization rate of the seedlings; on the other hand, considering the different actual sowing needs, the seedlings are at different growth stages, and the effective combing distance of the first combing component 42 is limited. Therefore, the guide member 43 is utilized to shorten the distance between the seedlings and the first combing component 42, thereby satisfying the need for seedlings in an earlier growth stage, that is, seedlings with a lower growth height, to a certain extent, and also achieving a good combing effect, thereby improving the transportation of seedlings in more possible growth stages.

[0062] Preferably, the material guide 43 is movably connected to the feed bin 41; wherein, when the material guide 43 is adjusted to move in a direction perpendicular to the rotation axis of the first combing assembly 42, the first distance is changed. For example, the material guide 43 is specifically manifested as a plate structure, which is screwed to the corresponding inner wall of the feed bin 41. The plate structure is provided with a waist-shaped hole extending in the vertical direction. Correspondingly, the inner wall is also provided with a waist-shaped groove adapted thereto. The material guide 43 is fixed to different positions of the medicinal hole by tightening bolts, thereby achieving the up and down movement of the material guide 43 in the feed bin 41, thereby changing the first distance, that is, the size of the first distance.

[0063] Furthermore, the guide member 43 includes, for example, a connecting portion 432 and a guiding portion 433. The connecting portion 432 is connected to the feed bin 41; the guiding portion 433 is connected to the side of the connecting portion 432 near the discharge port. The surface of the guiding portion 433 forms a guiding slope 431. The angle between the guiding slope 431 and the horizontal plane is smaller than the angle between the discharge guide surface 415 and the horizontal plane. Specifically, the guiding slope 431 extends diagonally downward toward the discharge guide surface 415, allowing the seedlings to be more smoothly guided onto the discharge guide surface 415 under the combing action of the first combing assembly 42.

[0064] Preferably, the seeding device 40 further includes, for example, a discharge bin 45 and a second combing assembly 44. The discharge bin 45 is located at a position corresponding to the second discharge port 412 of the feed bin 41; the second combing assembly 44 is rotatably connected to the discharge bin 45, forming a feed passage 451 between the discharge bin 45 and the second discharge port 412; wherein the feed passage 451 is located on one side of a coplanar surface 101 formed by the first axis of the second combing assembly 44 and the second axis of the first combing assembly 42, and the material guide 43 is located on the other side of the coplanar surface 101. The discharge bin 45 has a convergent effect on the seedlings introduced from the second discharge port 412, and combined with the setting of the second combing component 44, it can further ensure the uniform distribution of the seedlings introduced into the seedbed 60. By arranging the guide member 43 and the transfer channel 451 on both sides of the above-mentioned coplanar 101, the transfer channel 451 is located below the discharge guide surface 415, which effectively shortens the path of the seedlings from the sowing device 40 into the seedbed 60, thereby reducing the loss of seedlings during transportation.

[0065] Furthermore, when the first combing assembly 42 rotates around the first axis in a first direction and the second combing assembly 44 rotates around the second axis in a second direction opposite to the first direction, the target straw pile is guided into the feed channel 451 by the guide slope 431 .

[0066] In a specific example, the first combing component 42 includes, for example, a first roller 421 and at least one first paddle structure 422; the first roller 421 is rotatably connected to the feed bin 41; the first paddle structure 422 is installed to the circumferential surface of the first roller 421; wherein, the first paddle structure 422 is provided with a first paddle group 4221 and a second paddle group arranged along the extension direction of the first axis, and the first paddle group 4221 and the second paddle group are staggered in the circumferential direction corresponding to the circumferential surface.

[0067] In contrast, the second combing assembly 44, for example, includes a second roller 441 and at least one second paddle structure 442; the second roller 441 is rotatably connected to the discharge bin 45; the second paddle structure 442 is installed to the circumferential surface of the second roller 441; wherein, the second paddle structure 442 is provided with a third paddle group and a fourth paddle group arranged along the extension direction of the second axis, and the third paddle group and the fourth paddle group are staggered in the circumferential direction corresponding to the circumferential surface.

[0068] Furthermore, the first paddle group 4221 and the second paddle group have the same structure, and the two are staggered on the first roller 421 along its axial direction. Specifically, the first paddle group 4221 includes, for example, a first connecting plate 4223 and a plurality of first paddle members 4224; the first connecting plate 4223 is connected to the circumferential surface; the plurality of first paddle members 4224 are connected to opposite sides of the first connecting plate 4223 and are sequentially spaced along the extension direction of the first axis; any first paddle member 4224 has a first bent portion 4225, and the first bent portion 4226 is provided with a first bent portion 4227. The bending direction of 25 is set in the same direction as the rotation direction of the first combing component 42 when performing the combing action, and when the second combing component 44 includes a second roller 441 and at least one second paddle structure 442, the third paddle group and / or the fourth paddle group includes: a second connecting plate, the second connecting plate is connected to the circumferential surface; a plurality of second paddle members, and the plurality of second paddle members are arranged in sequence along the extension direction of the second axis; any second paddle member has a second bending portion, and the bending direction of the second bending portion is set in the opposite direction to the rotation direction of the first combing component 42 when performing the combing action.

[0069] Considering the actual growth of seedlings, a large number of target grass piles placed into the feed bin 41 cannot accurately guarantee the growth status of each seedling therein; for example, it is difficult to ensure that their growth stages are consistent. Consequently, some seedlings may have excessive branches or be at too early or too late a growth stage. If these are all transported to the seedbed 60 without any differentiation, the quality of the resulting lawn will be affected. Therefore, by properly arranging the spacing between the multiple first paddle elements 4224, the combing action can be effectively performed on the target seedlings in need, thereby minimizing damage to them.
