Description

Technical Field

[0001] The present invention relates to the technical field of seeders, and more specifically, to a small electric corn seeder for hilly and mountainous areas. Background Art

[0002] With the development of agricultural mechanization, the use of corn seeders has become increasingly widespread. A corn seeder refers to a planting machine that uses crop corn seeds as the sowing object. Corn seeders have the characteristics of uniform sowing, consistent depth, stable row spacing, good soil covering, seed saving, and high work efficiency. Corn seeders are divided into large corn seeders, medium-sized corn seeders, and small corn seeders. Small corn seeders are widely used in mountainous and hilly areas because they are flexible and convenient to transport.

[0003] In hilly and mountainous areas, there are generally terraced fields or mountain slopes that are not in the shape of fields. When planting on mountain slopes in the prior art, holes are usually dug on the mountain slopes, followed by sowing, fertilizing, burying soil, and then watering. However, the corn seeders in the prior art usually adopt excavation and then sowing. Most of these corn seeders are only suitable for sowing on flat land and are not suitable for sowing on slopes. Because after sowing, the seeds are sown on the slope, and the washing of rainwater easily causes the loss of fertilizer and soil. Moreover, the cost of excavating terraced fields on slopes is relatively high and the workload is large. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a small electric corn seeder for hilly and mountainous areas, which has a structure for preventing soil and water loss, can prevent soil and water loss and avoid excavating terraced fields, thereby reducing costs and workload.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A small electric corn seeder for hilly and mountainous areas, including a walking chassis, on which a frame is installed. On the frame, a flat ground trenching component for excavating a planting plane on the mountain slope, a protective structure forming component, a corn sowing component for sowing corn, an irrigation component for irrigating corn, a covering component for covering the protective structure forming component, and a main control module are installed;

[0007] The protective structure forming component includes a storage plate cavity, an elastic reset limiting component, a baffle, and a falling device for driving the baffle to fall. The storage plate cavity is a vertically arranged cavity, inside which several baffles formed by splicing multiple splicing plates are stacked up and down. At the bottom of the storage plate cavity, there is an outlet and a sliding hole. A limiting groove is opened on the side wall of the baffle. The elastic reset limiting component is installed inside the two side walls of the outlet. The elastic reset limiting component includes a limiting block and a reset spring. The limiting block horizontally abuts against the edge of the outlet through the reset spring and abuts into the limiting groove to block the baffle from falling;

[0008] The flat ditching component, the protective structure forming component, the seeding component, the irrigation component and the covering component are linked in operation sequence through the main control module.

[0009] The advantages of this solution are at least as follows: First, the main control module controls the start of the flat ditching component to excavate the planting platform on the hillside. Subsequently, the main control module controls the start of the dropping device, and the baffle formed by splicing multiple splicing plates is dropped from the inside of the storage plate cavity to the surface of the planting platform. The dropping device pressurizes the baffle, making the baffle more firmly inserted into the surface of the planting platform. During the descent of the baffle, due to the action of the elastic reset limiting component, when the stacked baffles fall, the dropping device presses down on the baffle, causing the limiting block to compress the reset spring and retract, and move out of the limiting groove, so that the baffle can perform the dropping action. Subsequently, when the next baffle descends to the exit and the limiting block is coaxial with the limiting groove, the limiting block is ejected into the limiting groove under the action of the reset spring, thereby blocking the fall of the next baffle. Through the above actions, the baffle is inserted into the surface of the planting platform through the dropping device on the excavated planting platform to construct a structure to prevent soil erosion, thus solving the problems of high cost and large workload in terracing on sloping land in the prior art.

[0010] After constructing the structure to prevent soil erosion, the main control module controls the seeding component to sow the planting platform first. After sowing is completed, the main control module controls the irrigation component to irrigate and moisten the seeds on the already sown planting platform. Subsequently, the main control module starts the covering component, and the covering component covers the planting platform that has been sown, irrigated and constructed with a structure to prevent soil erosion with forage. The covering of the forage on the planting platform can reduce the direct scouring of the sown flat land by rainwater, thereby further reducing soil erosion.

[0011] The present invention is further configured such that: the baffle is at least composed of two splicing plates connected through a splicing structure, and the splicing structure includes a groove and a protrusion provided on the side of the splicing plate, and adjacent splicing plates are spliced by the fitting of the groove and the protrusion.

[0012] The advantages of this solution are at least as follows: The baffle is spliced by two splicing plates through grooves and protrusions. When not in use, it has a small volume and is convenient for transportation. Moreover, in the face of different environments and terrains, it is convenient for quick splicing, so as to adapt to different terrains and environments.

[0013] The present invention is further configured such that: an elastic sealing layer is provided on the splicing joint surface of the groove and the protrusion, positioning holes with threads are provided at the bottom of the groove, through holes are provided at the corresponding positions of the protrusion, and after the splicing plates are spliced, double fixation is achieved by screwing locking bolts into the through holes and the positioning holes. A rubber anti-seepage layer with a thickness of 2 - 3 mm is compounded on the soil-facing surface of the splicing plate, and a reinforcing rib grid is provided on the soil-backing surface of the splicing plate.

[0014] The advantages of this solution are at least as follows: by respectively providing positioning holes with threads and through holes on the groove and the protrusion of the splicing plate, locking bolts are locked into the through holes, and through the double fixation of the locking bolts with the groove and the protrusion, the two splicing plates are firmly fixed together. An elastic sealing layer is provided on the splicing surface of the groove and the protrusion, and the elastic sealing layer increases the sealing effect between the groove and the protrusion, preventing water seepage. At the same time, a rubber anti-seepage layer is provided on the soil-facing surface, which can increase the anti-seepage ability of the baffle. A reinforcing rib grid is provided on the soil-backing surface of the baffle, which can further improve the anti-deformation ability.

[0015] The present invention is further configured such that: an anti-toppling vertical rod is connected to the bottom of the baffle, a round hole for the anti-toppling vertical rod to be inserted is provided at the top of the baffle, and the adjacent upper and lower baffles are stacked in the storage plate cavity by inserting the anti-toppling vertical rod into the round hole.

[0016] The advantages of this solution are at least as follows: an anti-toppling vertical rod is provided on the baffle. The design of the anti-toppling vertical rod can effectively prevent the baffle from tilting or collapsing, ensuring the stability of the structure. By providing a round hole for storing the anti-toppling vertical rod on the baffle, this stacking method of inserting the anti-toppling vertical rod into the round hole can maximize the utilization of the space in the storage plate cavity, enabling different baffles to be arranged compactly and increasing the storage capacity.

[0017] The present invention is further configured such that: the anti-toppling vertical rod is detachably connected to the bottom of the baffle through a threaded connection or a snap structure, and the end of the anti-toppling vertical rod away from the baffle is provided with a tapered shape, and barbs are provided on the surface of the tapered part.

[0018] The advantages of this solution are at least as follows: one end of the anti-toppling vertical rod is provided with a tapered shape, and the tapered design can better insert into the ground. Especially the part with barbs can effectively increase the friction with the ground, providing stronger fixing ability and preventing sliding or displacement during use. Through the threaded connection or the snap structure, the anti-toppling vertical rod can be conveniently connected and disassembled with the baffle, facilitating storage or maintenance and enhancing the flexibility of use.

[0019] The present invention is further configured as follows: The dropping device includes a first electric push rod, two second electric push rods, a first pressing plate and two second pressing plates. The first electric push rod is installed at the top of the plate storage cavity. The two second electric push rods are symmetrically installed on the outer side wall of the plate storage cavity. The first pressing plate and the second pressing plates are respectively installed at the output ends of the first electric push rod and the second electric push rods. Two vertical guiding blocks are installed on the side wall of the plate storage cavity away from the second electric push rod. The vertical guiding blocks are located on both sides of the outlet to ensure the verticality of the baffle when it drops.

[0020] The advantages of this solution are at least as follows: When performing the dropping action on the baffle, the first electric push rod is started through the control of the main control module. The first electric push rod drives the first pressing plate to move the baffles stacked up and down at the outlet downward. The vertical guiding blocks provide guidance for the stacked baffles up and down to ensure the verticality of the baffle when it drops. When continuous pressure is applied to the baffle, the limiting block compresses the return spring and retracts, and moves out of the limiting groove, so that the baffle performs the dropping action. Subsequently, when the next baffle drops to the outlet and the limiting block is coaxial with the limiting groove, the limiting block is ejected into the limiting groove under the action of the return spring to block the dropping of the next baffle. When the baffles stacked up and down at the outlet are used up, the second electric push rod is started through the control of the main control module. The second electric push rod drives the second pressing plate to move, and moves the baffles stacked up and down away from the outlet in the plate storage cavity to the outlet along the guidance of the vertical guiding blocks.

[0021] The present invention is further configured as follows: The flat ditching assembly includes a tool holder, rotary tillage tools, a motor and a soil scraping plate. The rotary tillage tools are rotatably installed on the tool holder, and the soil scraping plate is installed on the tool holder through a rigid bracket and an adjustable connecting rod. The tool holder is connected to the frame through a hydraulic lifting mechanism for excavating a horizontal planting plane on a slope.

[0022] The advantages of this solution are at least as follows: When it is necessary to excavate a planting platform on a hillside, the hydraulic lifting mechanism is started through the control of the main control module. The hydraulic lifting mechanism drives the tool holder and the rotary tillage tools on the tool holder to move downward. Subsequently, the motor is started, and the motor drives the rotary tillage tools to rotate to excavate the hillside. Finally, through the leveling of the soil scraping plate, the excavation of the planting platform is completed, preparing for the construction of the subsequent protective structure forming assembly.

[0023] The present invention is further configured such that: the rotary tillage cutter adopts arc-shaped blades arranged in a spiral pattern, and a wear-resistant coating is provided on the surface of the blades; the inclination angle of the soil scraping plate is steplessly adjusted from 0 to 30° through an adjustable connecting rod, and the adjustable connecting rod includes: a first connecting rod, a second connecting rod, and an adjusting rod. The first connecting rod and the second connecting rod are respectively rotatably mounted on a rigid support and the soil scraping plate, and one end of each of the first connecting rod and the second connecting rod has a thread. One end of the adjusting rod is threadedly connected to the first connecting rod, and the other end is threadedly connected to the second connecting rod.

[0024] The advantages of this solution are at least as follows: The blades arranged in a spiral pattern can achieve continuous cutting, optimize the cutting trajectory, and be able to break the soil more efficiently. The arc-shaped blade design can effectively adapt to the shape and changes of the soil, reduce soil resistance, and lower the resistance during tillage, thereby improving work efficiency. The wear-resistant coating on the surface of the blades significantly improves the durability of the cutter, reduces wear and replacement frequency during tillage, and through the stepless adjustment of the soil scraping plate from 0 to 30°, the scraping and leveling effect of the soil can be better controlled, and the angle can also be adjusted according to different tillage conditions (such as primary tillage, land preparation, topsoil treatment, etc.).

[0025] The present invention is further configured such that: the covering assembly includes a spreading disk and a crushing bin installed at the rear end of the frame, and the spreading disk is connected to the crushing bin through a feeding device and a diversion groove.

[0026] The advantages of this solution are at least as follows: After sowing, fertilizing, and watering are completed, the crushed forage in the crushing bin is transported to the spreading disk through the feeding device and the diversion groove, and the spreading disk covers the sown planting platform with forage, thereby reducing the scouring of rainwater on the sown flat ground and further reducing soil and water loss.

[0027] The present invention is further configured such that: in the crushing bin, there are arranged a moving knife group and a fixed knife group distributed alternately. The moving knife group includes three groups of arc-shaped blades circumferentially distributed at 120°, and each group of blades is arranged in a spiral pattern axially. The fixed knife group includes an array of inclined cutting edges with a spiral direction opposite to that of the moving knife group.

[0028] The advantages of this solution are at least as follows: The spiral arrangement of the blades in the moving knife group axially enables each group of blades to have a greater cutting length when contacting the material, increases the contact surface with the material, and promotes a good cutting effect when the material is crushed. In addition, the spiral arrangement can reduce the risk of material rebound or being thrown out of the bin. Through the ingenious cooperation of the moving knife and the fixed knife and their respective unique cutting methods, it helps to achieve a more uniform crushing effect.

[0029] In summary, the present invention has at least the following advantages:

[0030] 1. By setting up a protective structure forming component, first, the main control module controls the start of the flat ground and ditch opening component to excavate the planting platform on the hillside. Subsequently, the main control module controls the start of the dropping device, and the baffle plate composed of multiple splicing plates is dropped from the inside of the storage plate cavity to the surface of the planting platform. The dropping device pressurizes the baffle plate, making the baffle plate more firmly located on the surface of the inserted planting platform. During the descent of the baffle plate, due to the action of the elastic reset and limit component, when the stacked baffle plates fall, the dropping device presses down on the baffle plate, causing the limit block to compress the reset spring and retract, and move out of the limit groove, so that the baffle plate can perform a dropping action. Subsequently, when the next baffle plate descends to the exit and the limit block is coaxial with the limit groove, the limit block is ejected into the limit groove under the action of the reset spring, thus blocking the fall of the next baffle plate. Through the above actions, the baffle plate is inserted into the surface of the planting platform on the excavated planting platform by the dropping device, constructing a structure to prevent soil erosion, thus solving the problems of high cost, large workload, and soil erosion in the prior art when terracing on sloping land;

[0031] 2. By using the setting of at least two splicing plates to form a baffle plate, and an anti - toppling vertical rod is connected to the bottom of the baffle plate. The design of the anti - toppling vertical rod can effectively prevent the baffle plate from tilting or collapsing, ensuring the stability of the structure. One end of the anti - toppling vertical rod is set in a conical shape. The conical shape design can better insert into the ground or other surfaces. Especially the part with barbs can effectively increase the friction with the ground, providing stronger fixing ability to prevent sliding or displacement during use. Through threaded connection or snap - fit structure, the anti - toppling vertical rod can be conveniently connected to and disassembled from the baffle plate, facilitating storage or maintenance and enhancing the flexibility of use;

[0032] 3. By setting up a covering component, after sowing, fertilizing, and watering, the crushed forage in the crushing bin is transported to the spreading disk through the feeding device and the diversion trough, and the forage is spread on the sown planting platform through the spreading disk, thereby reducing the rainwater scouring of the sown flat ground and further reducing soil and water loss.

Specific embodiments

[0044] In order to more clearly understand the above - mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0045] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0046] Example 1:

[0047] As Figure 1 shown, a small electric corn planter for hilly and mountainous areas includes a walking chassis 1, on which an electric drive system and hydraulic leveling legs (not shown in the figure) are configured. The electric drive system includes motors installed at the front and rear ends of the frame, which are used to drive the wheels to move, enabling the chassis to move autonomously and operate flexibly in various working scenarios. The hydraulic leveling legs automatically or manually adjust the leg height according to different working environments to adapt to uneven or inclined ground. A frame 2 is installed on the walking chassis 1. Between the two motors of the electric drive system on the frame 2, a flat ground trenching component 3 for excavating the planting plane on the hillside, a protective structure forming component 4, a sowing component 5 for sowing corn, an irrigation component 6 for irrigating the corn sowing, a covering component 7 for covering the protective structure forming component 4, and a main control module (not shown in the figure) are installed. The flat ground excavation component 3 is installed at the front end of the frame 2. The protective forming component 4, the sowing component 5, the irrigation component 6, and the covering component 7 are installed in sequence from the front to the back of the frame 2. Among them, the sowing component 5 and the irrigation component 6 are installed side by side between the protective forming component 4 and the covering component 7;

[0048] The flat ground trenching component 3, the protective structure forming component 4, the sowing component 5, the irrigation component 6, and the covering component 7 achieve linkage of the operation time sequence through the main control module.

[0049] As Figures 2 - 5 shown, in some preferred embodiments, in order to better prevent soil and water loss, first, the flat ground trenching component 3 excavates a horizontal planting platform on the hillside to prepare for building a soil and water loss prevention structure for the protective structure forming component 4. The protective structure forming component 4 includes: a storage plate cavity 401, an elastic reset limiting component 402, a baffle 403, and a falling device 404 for driving the baffle 403 to fall. The storage plate cavity 401 is a vertically arranged cavity. An outlet 8 and a sliding hole 9 are provided at the bottom of the storage plate cavity 401. A limiting groove 10 is opened on the side wall of the baffle 403. The elastic reset limiting component 402 is installed inside the two side walls of the outlet 8. The elastic reset limiting component 402 includes a limiting block 4021 and a reset spring 4022. The limiting block 4021 laterally abuts against the edge of the outlet 8 and abuts into the limiting groove 10 through the reset spring 4022 to block the baffle 403 from falling. The limiting groove 10 is set as a circle in the attached drawing. In other embodiments, the limiting groove 10 can also be an ellipse arranged along the falling direction, located at a position below the middle of the baffle 403, and can also be set in the middle of the baffle 403, as long as the limiting groove 10 can cooperate with the elastic reset component 402 to limit the fall of the next baffle 403, and the baffle 403 can be firmly inserted into the surface of the planting platform under the action of the falling device 404;

[0050] Inside the storage plate cavity 401, several baffles 403 formed by splicing multiple splicing plates 4031 are stacked vertically. Among them, the baffle 403 is formed by at least two splicing plates 4031 connected through a splicing structure. In this embodiment, the splicing structure includes a groove and a protrusion provided on the side of the splicing plate 4031. Adjacent splicing plates 4031 are horizontally spliced through the fitting of the groove and the protrusion. In other embodiments, the splicing structure can be to fit two splicing plates 4031 together by means of a buckle, or to connect two splicing plates 4031 together by a bolt or a pin.

[0051] Furthermore, the dropping device 404 includes a first electric push rod 4041, two second electric push rods 4042, a first pressing plate 4043 and two second pressing plates 4044. The first electric push rod 4041 is installed at the top of the storage plate cavity 401. The two second electric push rods 4042 are symmetrically installed on the outer side wall of the storage plate cavity 401. The first pressing plate 4043 and the second pressing plate 4044 are respectively installed at the output ends of the first electric push rod 4041 and the second electric push rod 4042. Two vertical guiding blocks 18 are installed on the side wall of the storage plate cavity 401 far from the second electric push rod 4042. The vertical guiding blocks 18 are located on both sides of the outlet 8 to ensure the perpendicularity of the baffle 403 when it drops.

[0052] It is worth mentioning that since continuous operation is required for one seeding, in order to avoid the situation that the baffle 403 is not enough during seeding, in some preferred embodiments, a storage plate box for storing the baffle (not shown in the figure) can also be installed on the frame 2.

[0053] As Figure 6 shown, the flat ground and furrow opening assembly 3 includes: a tool holder 301, rotary tillage tools 302, a motor 305 and a soil scraping plate 303. The rotary tillage tools 302 are rotatably installed on the tool holder 301, and the soil scraping plate 303 is installed on the tool holder 301 through a rigid bracket 19 and an adjustable connecting rod 20. The tool holder 301 is connected to the frame 2 through a hydraulic lifting mechanism 304 for excavating a horizontal planting plane transversely on the slope surface. Among them, the rotary tillage tools 302 adopt arc-shaped blades arranged in a spiral manner, and wear-resistant coatings are provided on the surface of the blades; the inclination angle of the soil scraping plate 303 can be steplessly adjusted from 0 to 30° through the adjustable connecting rod 20 to adapt to different tillage conditions (such as primary tillage, soil preparation, topsoil treatment, etc.);

[0054] As Figure 7As shown in the figure, the adjustable connecting rod 20 includes: a first connecting rod 2001, a second connecting rod 2002, and an adjusting rod 2003. The first connecting rod 2001 and the second connecting rod 2002 are respectively rotatably installed on the rigid bracket 19 and the soil scraping plate 303, and one ends of the first connecting rod 2001 and the second connecting rod 2002 are both threaded. One end of the adjusting rod 2003 is threadedly connected to the first connecting rod 2001, and the other end is threadedly connected to the second connecting rod 2002. When adjusting the angle of the soil scraping plate 303, by rotating the adjusting rod 2003, the adjusting rod 2003 drives one ends of the first connecting rod 2001 and the second connecting rod 2002 to approach each other. The other ends of the first connecting rod 2001 and the second connecting rod 2002 respectively rotate on the rigid bracket 19 and the soil scraping plate 303, so that the soil scraping plate 303 rotates on the rigid bracket 19, thereby realizing the angle adjustment of the soil scraping plate 303;

[0055] Among them, the sowing assembly 5 includes a storage tank. A sowing pipe is fixedly installed below the storage tank. A cylinder is fixedly installed on one side of the sowing pipe. The output end of the cylinder is located inside the sowing pipe, and a telescopic block is installed at the end of the output end of the cylinder. During sowing, by controlling the cylinder, the telescopic block is driven to move in the telescopic pipe, and the opening and closing of the outlet 8 of the sowing pipe are realized. Some sowing assemblies 5 are also equipped with devices for digging holes and covering soil;

[0056] The irrigation assembly 6 includes a water tank installed on the frame. A water pump is installed inside the water tank. The output end of the water pump is installed with a hose, and the end of the hose is installed with a spray head. The spray head is arranged facing the ground. During irrigation, the main control module is used to control the water pump to start, and irrigation is carried out through the hose and the spray head. The above sowing assembly 5 and irrigation assembly 6 both belong to the prior art and will not be elaborated here.

[0057] As Figure 8 shown, in some embodiments, in order to increase the sealing effect between the two splicing plates 4031 and at the same time make the two splicing plates 4031 more firmly fixed together, an elastic sealing layer 11 is provided on the splicing joint surface of the groove and the protrusion. Threaded positioning holes 12 are provided at the bottom of the groove, through holes 13 are provided at the corresponding positions of the protrusions, and after the splicing plates 4031 are spliced, double fixation is realized by screwing in locking bolts. A rubber anti-seepage layer 14 with a thickness of 2 - 3 mm is compounded on the soil-facing surface of the splicing plate 4031, and a reinforcing rib grid is provided on the back soil surface of the splicing plate 4031. In this embodiment, the base body of the splicing plate 4031 is preferably made of polypropylene honeycomb board material. The polypropylene honeycomb board has a low density, light weight, is convenient for handling and installation, and at the same time has relatively high compressive and bending strengths.

[0058] As Figure 8 shown (refer to Figure 3), in order to improve the firmness of the baffle 403 fixed on the surface of the planting platform, in some embodiments, an anti-tip pole 15 is connected to the bottom of the baffle 403, and the end of the anti-tip pole 15 away from the baffle 403 is provided with a pointed cone shape, and barbs 17 are provided on the surface of the pointed cone part. The pointed cone shape design can be better inserted into the ground or other surfaces. Especially the part with barbs 17 can effectively increase the friction with the ground, provide stronger fixing ability, and prevent the baffle 403 from tipping during use. At the same time, a round hole 16 for placing the anti-tip pole 15 is opened at the top of the baffle 403. The upper and lower adjacent baffles 403 are stacked in the storage plate cavity 401 by inserting the anti-tip pole 15 into the round hole 16. This stacking method can maximize the space utilization of the storage plate cavity 401, so that different baffles 403 can be arranged compactly, increasing the storage capacity. It is worth mentioning that the anti-tip pole 15 is detachably connected to the bottom of the baffle 403 through a threaded connection or a snap structure. In this embodiment, a threaded connection is preferably used for convenient disassembly and installation.

[0059] As Figure 9 shown, in some embodiments, in order to reduce the rainwater scouring of the flat ground after sowing and further reduce the soil erosion, a covering device, a covering assembly 7, is installed on the frame 2, including a spreading disk 701 and a crushing bin 702 installed at the rear end of the frame 2. The spreading disk 701 and the crushing bin 702 are connected through a feeding device 704 and a diversion groove 703. In order to better crush the forage added to the crushing bin 702, a moving knife group 21 and a fixed knife group 22 are arranged in a staggered manner in the crushing bin 702. The moving knife group 21 includes three groups of arc-shaped blades circumferentially distributed at 120°, and each group of blades is arranged in a spiral shape axially. The fixed knife group 22 includes an array of inclined cutting edges with a rotation direction opposite to that of the moving knife group 21. The forage in the crushing bin 702 is crushed by the moving knife group 21 and the fixed knife group 22 in the crushing bin 702. The crushed forage is first transported from the crushing bin 702 to the spreading disk 701 through the feeding device 704 and the diversion groove 703, and the forage is spread by the spreading disk 701, so as to cover the planting platform, thereby reducing the direct scouring of the planting platform by rainwater.

[0060] Embodiment 2:

[0061] On the basis of Embodiment 1, the present invention also provides a sowing method for a corn seeder. Before sowing corn, first splice two splicing plates 4031, and screw locking bolts into the through holes 13 and the positioning holes 12 to achieve double fixation, complete the splicing of the baffle 403, and put multiple groups of spliced baffles 403 into the storage plate cavity 401.

[0062] When sowing corn, the main control module controls the hydraulic lifting mechanism 304 to start, which drives the tool holder 301 and the rotary tillage cutter 302 on the tool holder 301 to move downward, and starts the motor 305. The motor 305 drives the rotary tillage cutter 302 to rotate, thereby excavating the hillside. After excavation, the scraper plate 303 is used to flatten the excavated hillside to form a planting platform, preparing for the subsequent construction of the protective structure forming assembly 4;

[0063] Then, under the control of the main control module, the first electric push rod 4041 is started, and the first electric push rod 4041 drives the first pressure plate 4043 to move the baffles 403 stacked up and down at the outlet 8 downward. The vertical guide block 18 provides guidance for the stacked baffles 403 to ensure the verticality of the baffles 403 when falling. When pressure is continuously applied to the baffles 403, the limit block 4021 compresses the return spring 4022 and retracts it, and moves out of the limit groove 10. When the elastic return limit assembly 402 no longer restricts the baffle 403, the baffle 403 falls from the storage plate cavity 401 and is penetrated into the planting platform through the anti-inversion rod 15 with barbs 17, thereby forming a structure to prevent soil and water loss.

[0064] When the next baffle 403 falls to the outlet 8 and makes the limit block 4021 coaxial with the limit slot 10, the limit block 4021 is bounced into the limit slot 10 under the action of the return spring 4022, thereby preventing the next baffle 403 from falling naturally. When the baffles 403 stacked up and down at the outlet 8 are used up, the second electric push rod 4042 is started, and the second electric push rod 4042 drives the second pressure plate 4044 to move the remaining baffles 403 located in the storage plate cavity 401 along the sliding hole 9, and move the baffles 403 stacked up and down in the storage plate cavity 401 away from the outlet 8 along the guidance of the horizontal guide block to the outlet 8.

[0065] After the spliced baffle 403 is inserted into the planting plane, the structure for preventing soil and water loss is completed. Then, the sowing component 5 on the seeder is used to sow on the planting platform. After sowing, the sown planting platform is irrigated by the irrigation component 6. After irrigating, the main control module controls the start of the feeder 704, and the crushed grass in the crushing box is transported to the scattering plate 701 through the feeder 704 and the guide groove 703. Finally, the sown planting platform is covered with grass through the scattering plate 701, thereby preventing rainwater from directly washing the flat land after sowing, further reducing the possibility of soil and water loss. When the grass in the crushing bin 702 is insufficient, the grass on the hillside is manually harvested and the harvested grass is put into the crushing bin 702, and the grass is crushed by the staggered movable knife group 21 and fixed knife group 22 in the crushing bin 702, thereby providing grass for the scattering plate 701.

[0066] In the above seeding method, currently, a single baffle 403 is used to block in the vertical direction to achieve the effect of preventing soil erosion. However, in actual applications, multiple baffles 403 may be required to be used in a transverse splicing manner. The number of baffles 403 required is calculated according to the actual situation. Part of them are placed in the storage plate cavity 401, and the rest can be stored in a storage plate box (not shown in the figure) installed on the frame 2. The shapes formed by splicing multiple baffles 403 can be a straight line formed by arranging two or more baffles 403 horizontally, a rectangle formed by arranging four or more in a circular arrangement, a V shape formed by arranging two or more baffles 403, an inverted U shape formed by arranging three or more baffles 403, etc. In addition, since a small planting platform is excavated on the hillside and a structure for preventing soil erosion is constructed, the width of each baffle 403 spliced by the splicing plate 4031 is preferably between 50 and 80 cm, and the depth of the anti-fall vertical rod 15 inserted into the soil is preferably between 20 and 30 cm.

[0067] It is worth mentioning that the above seeding method can also be to first control through the main control module to start the flat ground excavation component 3 to excavate the planting platform on the hillside, then use the seeding component 5 to sow seeds on the planting platform. After sowing, the irrigation component 6 is used to irrigate the planted platform. After completing the above actions, the main control module controls the covering component 7 to cover the planted and irrigated platform with forage, and finally, the protection structure forming component 4 is used to construct a structure for preventing soil erosion.

[0068] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications once they know the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0069] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
