Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of agricultural planting, and specifically relates to an automatic seeding and soil covering device for rapeseed planting. Background Technique
[0002] Rapeseed (noun) refers to the seeds of vegetables, specifically rapeseed. Rapeseed is the seed of Brassica napus, an annual herbaceous plant in the Brassicaceae family, which is spherical in shape with an average diameter of 1.5 mm to 2.4 mm. Among the world's major oilseed yields, rapeseed ranks second only to soybeans. The main producing countries of rapeseed in the world include China, Canada, India, Pakistan and other countries.
[0003] Before sowing, it is necessary to deeply plow and harrow the land, remove certain weeds and stones to ensure that the soil is loose and breathable. At the same time, according to the soil fertility status, apply an appropriate amount of organic fertilizer or compound fertilizer as the base fertilizer. Then, the rapeseed seeds are scattered into the soil through a device, and then covered with soil. Currently, a disc soil covering device or a drag bent rod soil covering device is mostly used to cover the scattered seeds. However, it is very difficult to control the soil covering in this way, and it is easy to occur that the scattered rapeseed seeds are not covered with soil, which affects the soil covering rate of the rapeseed seeds, resulting in the abnormal growth of the rapeseed seeds. To ensure the normal soil covering and growth of the rapeseed seeds, it is necessary to manually check the soil covering and perform secondary soil covering. The secondary soil covering takes a long time and also affects the growth of the rapeseed seeds.
[0004] In order to reduce manual secondary operations and reduce the situation where the position of the soil covering deviates from the position of the scattered rapeseed seeds during the soil covering process, resulting in the scattered rapeseed seeds not being covered with soil, it is necessary to propose an automatic seeding and soil covering device for rapeseed planting that can reduce manual secondary operations, and at the same time achieve rapid and accurate soil covering and sufficient soil covering. Content of the Utility Model [[ID=IS]]
[0005] In order to solve the above problems, the purpose of the utility model is an automatic seeding and soil covering device for rapeseed planting, which achieves accurate soil covering and sufficient soil covering for the scattered rapeseed seeds through the mutual cooperation between the vertical trenching member, the soil covering plate and the soil covering wheel.
[0006] In order to achieve the above purpose, the technical solution of the utility model is as follows: an automatic seeding and soil covering device for rapeseed planting, including a first support assembly, a second support assembly and a first rotating rod. The first support assembly and the second support assembly are respectively located on both sides of the first rotating rod. Both ends of the second support assembly are fixedly connected with a first support rod, and the other ends of the two first support rods are respectively fixedly connected with both ends of the first support assembly;
[0007] A number of seeding assemblies are rotatably connected to the first rotating rod. Both ends of the first rotating rod are rotatably connected with a first fixing plate, and the bottom ends of the first fixing plates are respectively fixedly connected with one side of the first support rods;
[0008] The seeding assembly includes an input component rotatably connected to the first rotating rod. The bottom of the input component is connected to an output component in a communicating manner. The outer wall of the output component is provided with fixed buckles in a circular shape. One side of the fixed buckle is fixedly connected to a vertical ditching member, and the other side of the fixed buckle is fixedly connected to a soil covering plate. The soil covering plate is located on the opposite side of the vertical ditching member, and the movement trajectory of the soil covering plate and the movement trajectory of the vertical ditching member are on the same straight line, and the soil covering plate is in a "<" shape;
[0009] The second support assembly includes a soil covering wheel. The soil covering wheel is located in the movement trajectory of the soil covering plate. Both ends of the rotating shaft of the soil covering wheel are rotatably connected to second fixing plates. The tops of the second fixing plates are fixedly connected to fourth support rods. The fourth support rods are in an L-shaped mirror image. The tops of the fourth support rods are fixedly connected to the first support rod. A pushing assembly is provided above the soil covering wheel.
[0010] The principle of the basic scheme is: to move the traveling direction of the device through the pushing assembly, to provide a channel for seeding by the movement of the vertical ditching member, to spread rapeseed seeds into the channel through the input component and the output component in the seeding assembly, to accurately cover the soil generated by the movement of the vertical ditching member onto the spread seeds through the soil covering plate, and to reinforce the soil covered by the soil covering plate through the soil covering wheel.
[0011] The beneficial effects of the basic scheme are: 1. By setting the pushing assembly, the correct running trajectory of the device is determined, reducing the difficulty of subsequent ditching and soil covering caused by skewed running.
[0012] 2. By setting the vertical ditching component, the depth of the opened channel is better determined, ensuring the depth of seed planting, reducing the situation of uneven depths, which may cause different germination and growth speeds of seeds, thus increasing the harvesting difficulty.
[0013] 3. Through the mutual cooperation of the input component and the output component, the rapeseed seeds are spread into the channel more quickly, more evenly and automatically, reducing the uneven spreading of seeds and increasing the survival probability.
[0014] 4. Through the setting of the soil covering plate, the channel after spreading seeds is better covered with soil, ensuring that the seeds are fully covered with soil and increasing the survival probability.
[0015] 5. The vertical ditching member and the soil covering plate cooperate with each other and are on the same movement trajectory, increasing the accurate soil covering of the channel after spreading seeds.
[0016] 6. Through the setting of the soil covering wheel, the soil covered by the soil covering plate on the channel is reinforced, and at the same time, the channel is covered with soil more fully.
[0017] Furthermore, the first support assembly includes a transverse ditching wheel. On both sides of the transverse ditching wheel rotating shaft, there are third fixing plates rotatably connected. On the top of each third fixing plate, there is a second support rod fixedly connected. On the top of each second support rod, there is a third support rod fixedly connected. Between the tops of the third support rods, there are several fifth support rods fixedly connected.
[0018] Above the transverse ditching wheel, there is a motor. The motor is fixedly connected to the tops of several fifth support rods. The output shaft of the motor is coaxially fixedly connected with a first gear. There is a first rack on the first gear. On the side of the transverse ditching wheel rotating shaft close to the motor, there is a second gear coaxially fixedly connected. The first gear and the second gear are in transmission cooperation through the first rack.
[0019] The beneficial effects of the basic solution are as follows: 1. Through the cooperation of the second support rod, the third support rod and the fifth support rod, the stability of the device is ensured.
[0020] 2. Through the setting of the fifth support rod, a position is provided for the installation of the motor, ensuring the stability of the motor installation.
[0021] 3. Through the setting of the transverse ditching wheel, the soil is loosened and a transverse ditch is dug in the soil, which facilitates the movement and vertical ditching of the vertical ditching member and completes the sowing of seeds.
[0022] 4. Through the mutual cooperation among the motor, the first gear, the second gear, the transverse ditching wheel and the first rack, the soil is loosened more labor - savingly, providing convenience for vertical ditching.
[0023] 5. Through the support and stabilizing functions of the third fixing plate and the second support rod, the stability and safety of the transverse ditching wheel during operation are ensured.
[0024] Furthermore, the input component includes a storage bin rotatably connected to the first rotating rod. At the top of the storage bin, there is a feeding pipe 1 connected. The feeding pipe 1 is in the shape of an hourglass with a wider top and a narrower bottom. On the side of the feeding pipe close to the motor, there is a feeding cover hinged.
[0025] The beneficial effects of the basic solution are as follows: 1. Through the setting of the storage bin, a position is provided for storing rapeseed seeds.
[0026] 2. Since rapeseed seeds are granular, the feeding pipe is set in the shape of an hourglass with a wider top and a narrower bottom, which is conducive to rapeseed seeds entering the storage bin and reducing the waste of rapeseed seeds.
[0027] 3. Through the setting of the feeding cover, the rapeseed seeds are prevented from falling out of the feeding port due to external forces during the operation of the device, resulting in the loss of rapeseed seeds.
[0028] Furthermore, the output component includes a discharge pipe connected to the bottom of the storage bin. The side of the discharge pipe close to the vertical ditching member is inclined.
[0029] The beneficial effects of the basic solution are: 1. By setting the discharge pipe, the flow direction of the rapeseed seeds is determined to ensure that the rapeseed seeds are spread into the channels opened by the vertical trenching members.
[0030] 2. The side of the discharge pipe close to the vertical trenching piece is inclined to reduce the contact area between the discharge pipe and the soil, reduce the possibility of soil blocking the discharge pipe, and reduce the dust generated when the covering plate is covered with soil and adhere to the discharge pipe.
[0031] Furthermore, the first rotating rod is fixedly connected to a number of limiting parts corresponding to the sowing components respectively. The limiting parts are respectively located in the middle of the storage bin and aligned with the top of the discharge pipe. The limiting parts include a limiting ring arranged on the first rotating rod, and a number of flow limiting blades are fixedly connected to the limiting ring.
[0032] The basic solution has the following beneficial effects: by setting the limiter, the rapeseed seeds can be quantitatively spread into the channel opened by the vertical furrowing member, reducing the accumulation of rapeseed seeds. When the rapeseed seeds are subsequently fertilized, some rapeseed seeds cannot absorb sufficient nutrients due to the accumulation of large amounts of rapeseed seeds, resulting in abnormal growth. Therefore, the limiter setting can be used to quantitatively spread the rapeseed seeds, thereby increasing the survival rate of the rapeseed seeds.
[0033] Furthermore, one end of the first rotating rod is fixedly connected to a third gear, a second rack is provided on the third gear, the third gear is located on the side of the first fixed plate close to the motor, the transverse grooving wheel shaft is fixedly connected to a fourth gear, the fourth gear is located on the side of the second gear away from the transverse grooving wheel, and the third gear and the fourth gear are matched through the second rack transmission.
[0034] The beneficial effect of the basic solution is that the third gear, the fourth gear and the second rack cooperate with each other to drive the limiter to move and control the amount of rapeseed seeds spread.
[0035] Furthermore, a first cross bar is fixedly connected between two adjacent fixing buckles, a second cross bar is fixedly connected to the inner side of the first support rod, the second cross bar is fixedly connected to the fixing buckle, and the first cross bar and the second cross bar are on the same horizontal plane.
[0036] The beneficial effect of the basic solution is that the sowing assembly is fixedly connected to the first support rod through the arrangement of the first cross bar and the second cross bar, thereby ensuring the normal operation and normal working of the sowing assembly while improving the stability of the sowing assembly.
[0037] Furthermore, the pushing assembly includes a sixth support rod, which is fixedly connected between the first support rods. Both ends of the sixth support rod are fixedly connected to the first support member, which is in the shape of a triangular plate, and the inclined surface of the first support member is fixedly connected to a handle.
[0038] The beneficial effects of the basic solution are as follows: Through the setting of the handle, the operator can more conveniently control the running direction of the device, as well as its stop and start.
[0039] Furthermore, the transverse trenching wheel is in the shape of a transverse cylinder. A number of transverse trenching members are fixedly connected to the transverse trenching wheel along the height direction. The transverse trenching members are serrated. Filter grooves are provided between every two transverse trenching members. A number of first filtering members are fixedly connected to the filter grooves along the length direction. The first filtering members are arranged in parallel between the transverse trenching members.
[0040] The beneficial effects of the basic solution are as follows: By setting the transverse trenching members on the transverse trenching wheel, it is beneficial to disperse the soil while the transverse trenching wheel rotates.
[0041] Furthermore, a number of discharge ports are provided on the side of the transverse trenching wheel away from the motor. Second filtering members are provided at the discharge ports. A sheath is provided around the internal rotating shaft of the transverse trenching wheel. A guiding plate is fixedly connected inside the transverse trenching wheel. The guiding plate is located between the two filter grooves.
[0042] The beneficial effects of the basic solution are as follows: 1. Through the setting of the sheath, it can protect the internal rotating shaft of the transverse trenching wheel to operate safely. [[ID=**13**]] [[ID=**14**]]
[0043] [[ID=**15**]]2. By setting the second filtering members at the discharge ports, medium and small stones can be filtered out of the inside of the transverse trenching wheel, while large stones are retained inside the transverse trenching wheel. The lumpy soil will collide with the inner wall as the transverse trenching wheel rotates, dispersing the lumpy soil. The retained stones and lumpy soil will also collide when rotating with the transverse trenching wheel, accelerating the pulverization of the lumpy soil.

Detailed implementation mode
[0051] The following is a further detailed description through specific implementation modes:
[0052] Example 1, basically as shown in the attached Figure 1 - attached Figure 6 As shown: The specific implementation process is as follows: An automatic seeding and soil covering device for rapeseed planting includes a first support assembly, a second support assembly, and a first rotating rod 8. The first support assembly and the second support assembly are respectively located on both sides of the first rotating rod 8. Both ends of the second support assembly are welded with first support rods 7, and the other ends of the two first support rods 7 are respectively welded to both ends of the first support assembly;
[0053] A plurality of seeding assemblies are provided on the first rotating rod 8. Both ends of the first rotating rod 8 are rotatably connected with first fixing plates 9, and the bottom ends of the first fixing plates 9 are respectively fixedly connected to one side of the first support rods 7;
[0054] The seeding assembly includes an input assembly rotatably connected to the first rotating rod 8 through a bearing. The bottom of the input assembly is communicated with an output assembly. A fixed buckle 24 is sleeved on the outer wall of the output assembly. One side of the fixed buckle 24 is welded with a vertical trench opening member 27, and the other side of the fixed buckle 24 is welded with a soil covering plate 25. The soil covering plate 25 is located on the opposite side of the vertical trench opening member 27, and the movement track of the soil covering plate 25 and the movement track of the vertical trench opening member 27 are on the same straight line, and the soil covering plate 25 is in an inverted "L" shape;
[0055] The second support assembly includes a soil covering wheel 5. The soil covering wheel 5 is located in the movement track of the soil covering plate 25. Both ends of the rotating shaft of the soil covering wheel 5 are rotatably connected to second fixing plates 34. At the top of each of the second fixing plates 34, a fourth support rod 6 is fixedly connected. The fourth support rods 6 are mirror L-shaped. The tops of the fourth support rods 6 are fixedly connected to the first support rods 7. A pushing assembly is provided above the soil covering wheel 5.
[0056] The specific implementation process is as follows: When the operator first pours rapeseed seeds into the input assembly and applies force through the pushing assembly to start the device, the vertical trenching member 27 contacts the soil and opens a vertical channel in the soil. Since the vertical trenching member 27 is welded to the fixed buckle 24, the up and down displacement of the vertical trenching member is limited. Therefore, it can ensure that the opened channels are of the same depth and width. The soil dug by the vertical trenching member 27 to form the channels will accumulate on both sides of the channels to form small sand piles. Since the output assembly and the vertical trenching member 27 are on the same horizontal line, the rapeseed seeds can accurately pass through the output assembly and fall into the channels opened by the vertical trenching member 27, reducing the situation of seeds falling randomly.
[0057] The movement track of the soil covering plate 25 is the same as that of the vertical trenching groove. At the same time, the soil covering plate 25 is in an inverted "L" shape. The advantage of this setting is that the soil brought out by the vertical trenching member 27 can be completely covered on the rapeseed seeds after spreading through the movement of the soil covering plate 25. Since the soil covering plate 25 is also welded to the fixed buckle 24, the vertical position of the soil covering plate 25 is limited. Therefore, the contact height between the soil covering plate 25 and the soil is also limited. In addition, the soil covering plate 25 and the vertical trenching member 27 move on the same straight line. Therefore, as the device moves, the soil covering plate 25 covers the soil generated by the vertical trenching member 27 back into the channels after spreading rapeseed seeds, making the thickness of the covered soil almost the same. At the same time, the excess soil will also continue to move with the soil covering plate 25, reducing soil accumulation.
[0058] The movement track of the soil covering wheel 5 is within the movement track of the soil covering plate 25. Therefore, the soil covering wheel 5 will pass through the position after the soil covering plate 25 covers the soil, thereby strengthening the soil covering of the rapeseed seeds in the channels. In addition, the rapeseed seeds are initially covered by the soil covering plate 25 and then secondarily covered by the soil covering wheel 5, realizing sufficient soil covering for the rapeseed seeds.
[0059] Embodiment 2
[0060] The difference from the above embodiment is that the first support assembly includes a transverse trenching wheel 19. Both sides of the rotating shaft of the transverse trenching wheel 19 are rotatably connected to third fixing plates 30. At the top of each of the third fixing plates 30, a second support rod 13 is welded. At the top of each of the second support rods 13, a third support rod 16 is welded. Between the tops of the third support rods 16, a plurality of fifth support rods 18 are welded;
[0061] Above the horizontal trenching wheel 19 is provided with a motor 17. The motor 17 is welded to the tops of several fifth support rods 18. The output shaft of the motor 17 is coaxially welded with a first gear 20. A first rack 21 is provided on the first gear 20. On the side of the rotating shaft of the horizontal trenching wheel 19 close to the motor 17, a second gear 22 is coaxially welded. The first gear 20 and the second gear 22 are in transmission cooperation through the first rack 21.
[0062] The specific implementation process is as follows: The positional relationship among the first support rod 7, the second support rod 13, the third support rod 16, and the fifth support rod 18 provides the necessary conditions for the stable operation of the device.
[0063] Relying solely on the operator to control the normal operation of the device through the pushing component will be time-consuming and more laborious, increasing the manual workload. Therefore, a motor 17 is fixedly connected to the fifth support rod 18 to provide a certain amount of power for the device. The output shaft of the motor 17 is fixedly connected to the first gear 20, and the rotating shaft of the horizontal trenching wheel 19 is fixedly connected to the second gear 22. The first gear 20 and the second gear 22 are in transmission cooperation through the first rack 21. When the motor 17 is started, the motor 17 rotates to drive the first gear 20 to drive the first rack 21 to move and simultaneously drive the horizontal trenching member 12 to move. At this time, the operator only needs to control the running direction of the device through the pushing component, without spending more force to drive the horizontal trenching member 12 to run, enabling the device to operate normally while saving more manpower requirements.
[0064] Embodiment 3
[0065] The difference from the above embodiment is that the input component includes a storage bin 35 rotatably connected to the first rotating rod 8. The top of the storage bin 35 is communicated with a feed pipe 1. The feed pipe 1 is in the shape of an hourglass with a wider upper part and a narrower lower part. A feed cover 23 is hinged to the side of the feed pipe 1 close to the motor 17;
[0066] The output component includes a discharge pipe 26 communicated with the bottom of the storage bin 35. The side of the discharge pipe 26 close to the vertical trenching member 27 is an inclined surface;
[0067] The first rotating rod 8 is fixedly connected with a number of limiting members corresponding to the sowing component respectively. The limiting members are respectively located in the middle of the storage bin 35 and aligned with the top of the discharge pipe 26. The limiting members include a limiting ring 36 sleeved on the first rotating rod 8, and a number of flow-limiting fan blades 37 are fixedly connected to the limiting ring 36;
[0068] One end of the first rotating rod 8 is welded with a third gear 10. A second rack 15 is provided on the third gear 10. The third gear 10 is located on the side of the first fixing plate 9 close to the motor 17. The rotating shaft of the horizontal trenching wheel 19 is also welded with a fourth gear 14. The fourth gear 14 is located on the side of the second gear 22 away from the horizontal trenching wheel 19. The third gear 10 and the fourth gear 14 are in transmission cooperation through the second rack 15.
[0069] The specific implementation process is as follows: The operator pours rapeseed seeds into the feed pipe 1 respectively. During the pouring process, the rapeseed seeds enter the storage bin 35, increasing the storage capacity of the rapeseed seeds and reducing the number of repeated additions. After pouring a certain amount, cover the feed cover 23 to prevent the rapeseed seeds from falling out of the feed port under the action of force during the operation of the device, resulting in waste of rapeseed seeds.
[0070] The storage bin 35 is connected with a discharge pipe 26. When the rapeseed seeds are poured into the storage bin 35, the seeds will directly reach the channel opened by the vertical ditching member 27 through the discharge pipe 26, resulting in the accumulation and sowing of rapeseed seeds. The situation that the device cannot scatter the rapeseed seeds into the channel opened by the vertical ditching member 27 is not solved. One end of the first rotating rod 8 is fixedly connected with a third gear 10. The third gear 10 and the fourth gear 14 are in transmission cooperation through the second rack 15. When the fourth gear 14 moves with the transverse ditching wheel 19, it drives the second rack 15 to operate, thereby driving the third gear 10 to move. The movement of the third gear 10 drives the first rotating rod 8 to rotate, thereby driving the limiting ring 36. The rotation of the limiting ring 36 drives the flow-limiting fan blade 37 to move, quantitatively conveying the rapeseed seeds in the storage bin 35, solving the problem that the rapeseed seeds directly fall from the storage bin 35 through the discharge pipe 26 into the soil, and thus achieving the quantitative scattering of rapeseed seeds.
[0071] During the operation of the device, to prevent the discharge pipe 26 from directly contacting the soil, resulting in the blockage of the discharge pipe 26, the side of the discharge pipe 26 close to the vertical ditching member 27 is set as an inclined plane. The soil will fall out along the inclined plane under the action of gravity and the vibration during the sowing process of the device, reducing the probability of blockage caused by soil adhering to the discharge pipe 26.
[0072] Embodiment 4
[0073] The difference from the above embodiment is that a first cross bar 2 is welded between two adjacent fixed buckles 24;
[0074] Second cross bars are welded inside the first support rods 7. The second cross bars are all welded with fixed buckles 24. The first cross bar 2 and the second cross bar are on the same horizontal plane.
[0075] The specific implementation process is as follows: The storage bins 35 are all connected with a first rotating rod 8. Both ends of the first rotating rod 8 are rotatably connected to the first fixing plates 9. The first fixing plates 9 are fixedly connected to the first support rods 7, providing stability for the storage bins 35. However, the stability of the discharge pipe 26, the vertical ditching member 27 and the soil covering plate 25 during operation cannot be guaranteed, which may cause the discharge pipe 26, the vertical ditching member 27 and the soil covering plate 25 to fail to work properly. Therefore, through the mutual connection between the first cross bar 2, the fixed buckle 24, the second cross bar and the first support rod 7, the displacement between components is mutually restricted, providing stable operating conditions for the discharge pipe 26, the vertical ditching member 27 and the soil covering plate 25.
[0076] Example 5
[0077] The difference from the above embodiments is that the pushing component includes a sixth support rod 4, the sixth support rod 4 is welded between adjacent first support rods 7, and first support members 33 are welded to both ends of the sixth support rod 4. The first support members 33 are in the shape of triangular plates, and a handle 3 is fixedly connected to the inclined surface of the first support members 33.
[0078] The specific implementation process is as follows: The operator applies force to the handle 3 to control the running direction of the device, ensuring that the rapeseed seeds can be evenly scattered in a straight line. In addition, through the mutual welding between the first support member 33, the handle 3, the sixth support rod 4 and the first support rod 7, the device can achieve overall passivity controlled by the operator during operation, improving the stability of the device.
[0079] Example 6
[0080] The difference from the above embodiments is that the transverse trenching wheel 19 is a transverse cylindrical shape, and a plurality of transverse trenching members 12 are welded along the height direction of the transverse trenching wheel 19. The transverse trenching members 12 are serrated, and filter grooves are provided between two transverse trenching members 12. A plurality of first filter members 11 are welded along the length direction of the filter grooves, and the first filter members are arranged in parallel between the transverse trenching members 12.
[0081] A plurality of discharge ports 29 are provided on the side of the transverse trenching wheel 19 away from the motor 17. A second filter member 28 is provided at the discharge ports 29. A sheath 32 is provided around the internal rotating shaft of the transverse trenching wheel 19, and a guide plate 31 is fixedly connected inside the transverse trenching wheel 19. The guide plate 31 is located between the two filter grooves.
[0082] The specific implementation process is as follows: When the transverse trenching wheel 19 is working normally, the transverse trenching members 12 contact the soil to complete the soil loosening work, facilitating the operation of the vertical trenching members 27 and reducing the probability that the vertical trenching members 27 cannot break through the soil due to the hard soil. Since the transverse trenching members 12 cannot completely disperse the massive soil quickly and will also leave the ground with the rotation of the transverse trenching wheel 19 and quickly fall back to the ground under the influence of gravity. During the falling process, the massive soil will also contact the transverse trenching members 12 and enter the transverse trenching wheel 19 through the transverse trenching members 12 and contact the first filter members 11. There will also be stones of different specifications in the soil, and the stones will also enter the transverse trenching wheel 19 through the transverse trenching members 12 and the first filter members 11.
[0083] In order to reduce the influence of massive soil and stones on the rotating shaft in the transverse trenching wheel 19, a sheath 32 is sleeved outside the rotating shaft to reduce the probability of damage to the trenching wheel 19 caused by the impact of soil and stones and affecting the normal operation.
[0084] As the lateral ditching wheel 19 runs, the lumpy soil in the lateral ditching wheel 19 will impact the inner wall of the lateral ditching wheel 19, thereby dispersing the lumpy soil. Some of the dispersed soil flows out from the first filter member 11 and returns to the field to cover the rapeseed seeds.
[0085] An outlet 29 is provided on one side of the lateral ditching wheel 19, and a second filter member 28 is arranged at the outlet 29. During the operation of the lateral ditching wheel 19, the stones smaller than the second filter member 28 will move out of the lateral ditching wheel 19, leaving the stones with a volume larger than the second filter member 28. The remaining stones continue to move irregularly in the lateral ditching wheel 19 and will also impact the lumpy soil in the lateral ditching wheel 19, accelerating the dispersion of the lumpy soil.
