Description

Technical Field

[0001] The present invention relates to the technical field of seeding machine equipment, and particularly relates to a seeding machine for planting fruit corn. Background Art

[0002] With the development of modern agriculture, the demand for improving planting efficiency and crop yield is increasing day by day. As a crop with high nutritional value and economic value, the market demand for fruit corn continues to grow. The traditional planting method of fruit corn mostly relies on manual seeding. This method not only has a large labor intensity and low efficiency, but also is difficult to ensure the uniformity of seeding and the consistency of depth, thus affecting the growth quality and final yield of the crop. Therefore, the seeding machine for fruit corn planting has become an important direction for the development of modern agricultural technology.

[0003] During the seeding process, problems such as underground pests gnawing on seeds and birds pecking at the seeds often occur. These problems will all lead to a decrease in the seed germination rate. To solve this problem, the traditional method is to use a seed dressing agent to treat the seeds before seeding. However, in actual operation, the dressing agent may partially fall off during the seeding process, thus affecting its insect repellent effect and unable to effectively protect the seeds from pest damage. And most of the current seeding machines on the market only have simple seeding and soil covering functions. Even if some models can apply fertilizers simultaneously, they do not provide an effective solution for pest control. Therefore, we propose a seeding machine for fruit corn planting to solve the above problems. Summary of the Invention

[0004] In order to overcome the above-mentioned disadvantages of the prior art, the present invention provides a seeding machine for fruit corn planting, which realizes the automatic dressing and seeding of corn seeds.

[0005] Technical solution: A seeder for planting fruit corn, including a frame, which is the main frame of this seeder. Electric wheels are symmetrically installed on both left and right sides of the frame. An operation handle convenient for users to operate is fixedly installed at the top of the rear side of the frame. It also includes a seed box fixedly installed on the front side of the frame through a mounting rod. The seed box is circular and multiple are arranged at intervals. On one side of the upper part of the seed box, there is a feeding port for adding corn seeds. On one side of the lower part of the seed box, there is a notch. On the front side of the frame, a plurality of outer rings are fixedly connected through fixed rods. The number of outer rings is the same as that of the seed boxes, and the outer rings are respectively located around the corresponding seed boxes. A rotating ring is rotatably installed between the outer ring and the corresponding seed box. Each rotating ring is connected into a whole. A plurality of ring grooves adapted to the notches of the seed boxes are circumferentially provided on the rotating ring. When the ring grooves of the rotating ring are aligned with the notches of the seed boxes, the corn seeds in the seed box will fall into the ring grooves of the rotating ring. A driving member for driving the rotating ring to rotate is provided on the frame. At the bottom opening of the outer ring, there is a seed dressing mechanism for mixing seeds and seed dressing agent. The seed dressing mechanism includes a mixing cylinder fixedly installed at the bottom of the outer ring. The mixing cylinder is communicated with the bottom opening of the outer ring. The mixing cylinder is filled with powdery seed dressing agent. An outlet for the seeds to slide out is opened on the upper part of the cylinder wall of the mixing cylinder. A sieve ring is slidably installed in the mixing cylinder in a fitting manner. The top of the sieve ring is a slope and is equipped with a sieve mesh. The sieve mesh is used to sieve out the seeds after seed dressing upwards. An elevating member for driving the sieve ring to lift and lower is provided on the outer ring.

[0006] As an improvement of the above solution, the driving member includes a motor, a gear and a toothed ring. A motor is fixedly installed on one side of the frame. A gear is fixedly connected to the output shaft of the motor. A toothed ring is fixedly connected to the inner wall of the ring body on the side of the rotating ring close to the motor. The gear and the toothed ring are meshed with each other. The motor drives the toothed ring and the rotating ring to rotate through gear meshing. The ring grooves on the rotating ring can sequentially align with the notches of the seed boxes, so that the corn seeds in the seed box can intermittently fall into the ring grooves of each rotating ring. The ring grooves of the rotating ring can intermittently carry the corn seeds and fall into the mixing cylinder.

[0007] As an improvement of the above solution, the elevating member includes a cylinder one, a connecting rod one and a magnet one. A cylinder one is fixedly installed on the outside of the outer ring. The telescopic rod of the cylinder one faces downwards and is fixedly connected to a connecting rod one. A magnet one is assembled at the rod end of the connecting rod one. A magnet two is assembled on the side of the sieve ring close to the magnet one. The magnet one and the magnet two have different magnetic poles. The cylinder one drives the magnet one on the connecting rod one to reciprocate up and down, so that the magnet one can drive the sieve ring to reciprocate up and down in the mixing cylinder by adsorbing the magnet two.

[0008] As an improvement of the above solution, a seed feeding mechanism for assisting sowing is provided on one side of the outer ring close to the seed dressing mechanism. The seed feeding mechanism includes a second cylinder, a second connecting rod and a seed dropping cylinder. The second cylinder is fixedly installed on the outer side of the outer ring. The telescopic rod of the second cylinder faces downward and is fixedly connected to the second connecting rod. The rod end of the second connecting rod is fixedly installed with a seed dropping cylinder. A docking groove for cooperating with the seed outlet is provided on one side of the cylinder wall of the seed dropping cylinder close to the mixing cylinder. The docking groove of the seed dropping cylinder is in sliding contact with the mixing cylinder. A soil breaking member for breaking soil for sowing is provided at the bottom of the seed dropping cylinder.

[0009] As an improvement of the above solution, the soil breaking member includes a conical flap and a motor. The bottom of the barrel of the seed dropping cylinder is a through port. The conical flap is circumferentially rotatably connected to the through port at the bottom of the seed dropping cylinder. The conical flaps form a pointed cone block at the bottom of the seed dropping cylinder. A plurality of motors are fixedly installed at intervals in the circumferential direction at the bottom of the barrel of the seed dropping cylinder. The output shaft of the motor is connected to the rotating shaft of the corresponding conical flap. When the second cylinder drives the seed dropping cylinder to descend, the closed conical flaps insert corresponding sowing soil grooves in the soil, and then the motor is activated to drive the conical flaps to rotate and unfold at the bottom of the seed dropping cylinder, so that the corn seeds falling into the conical flaps can fall into the sowing soil grooves in the soil.

[0010] As an improvement of the above solution, a first sensor is assembled on one side of the upper barrel of the mixing cylinder. The first sensor is used to monitor whether seeds fall into the mixing cylinder. The first sensor has a built-in controller and is electrically connected to the first cylinder. The first sensor can control the working state of the first cylinder through the controller. A second sensor is assembled in the docking groove of the seed dropping cylinder. The second sensor is used to monitor whether seeds enter the seed dropping cylinder. The second sensor has a built-in controller and is electrically connected to the second cylinder. The second sensor can control the working state of the second cylinder through the controller.

[0011] As an improvement of the above solution, a fertilizing mechanism for fertilizing is provided on one side of the bottom of the seed dropping cylinder. The fertilizing mechanism includes a fertilizer cylinder fixedly connected to one side of the bottom of the seed dropping cylinder. The fertilizer cylinder contains granular corn fertilizer. An air pump is fixedly installed on the outer wall of the fertilizer cylinder. The air pump is connected to the inside of the fertilizer cylinder through a pipeline. The bottom of the fertilizer cylinder is a conical opening. A check valve for releasing fertilizer is provided at the outlet of the conical opening. The fertilizer cylinder will be inserted into the soil synchronously with the seed dropping cylinder. When the telescopic rod of the second cylinder extends to the maximum stroke, a preset program controls the air pump to charge a section of high-pressure air into the fertilizer cylinder, so that the high-pressure air briefly opens the check valve, and the corn fertilizer in the fertilizer cylinder can be added to the soil layer near the corn seeds.

[0012] As an improvement of the above solution, a watering mechanism for watering after sowing is provided at the rear side of the rack. The watering mechanism includes a water tank fixedly installed at the rear side of the rack. A water pump is installed in the water tank. A plurality of downwardly extending water outlet pipes are provided at the front side of the water tank. The number of the water outlet pipes is the same as that of the seed boxes. Sprayers are installed at the water outlet ends of the water outlet pipes. The outlet of the water pump is communicated with each water outlet pipe through a connecting pipe. After the seeder completes the sowing and fertilizing of corn seeds, the water pump pumps the water in the water tank into the water outlet pipes under high pressure, and then sprays the water onto the sown soil through a plurality of sprayers.

Detailed implementation manners

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0027] Embodiment 1: A seeding machine for planting fruit corn, as Figures 1-4As shown in the figure, it includes a frame 1, which is the main frame of this seeder. Electric wheels 2 are symmetrically installed on both the left and right sides of the frame 1. At the top of the rear side of the frame 1, an operation handle 3 convenient for users to operate is fixedly installed. It also includes a seed box 4 fixedly installed on the front side of the frame 1 through a mounting rod 41. The seed box 4 is circular and multiple seed boxes 4 are arranged at intervals. On one side of the upper part of the seed box 4, there is a feeding port 42 for adding corn seeds. On one side of the lower part of the seed box 4, there is a notch. On the front side of the frame 1, a plurality of outer rings 5 are fixedly connected through a fixing rod 51. The number of the outer rings 5 is the same as that of the seed boxes 4. The outer rings 5 are respectively located outside the corresponding seed boxes 4. A rotating ring 6 is rotatably installed between the outer ring 5 and the corresponding seed box 4. Each rotating ring 6 is connected into a whole. A plurality of annular grooves 61 adapted to the notches of the seed box 4 are circumferentially formed on the rotating ring 6. When the annular grooves 61 of the rotating ring 6 are aligned with the notches of the seed box 4, the corn seeds in the seed box 4 will fall into the annular grooves 61 of the rotating ring 6. A driving member 7 for driving the rotating ring 6 to rotate is provided on the frame 1. At the bottom opening of the outer ring 5, there is a seed dressing mechanism 8 for mixing seeds and seed dressing agent. The seed dressing mechanism 8 includes a mixing cylinder 81 fixedly installed at the bottom of the outer ring 5. The mixing cylinder 81 is communicated with the bottom opening of the outer ring 5. The mixing cylinder 81 is filled with powdery seed dressing agent. An outlet 811 for seeds to slide out is formed in the upper part of the barrel wall of the mixing cylinder 81. A sieve ring 82 is slidably installed in the mixing cylinder 81 in a fitting manner. The top of the sieve ring 82 is a slope and is equipped with a sieve mesh 821. The sieve mesh 821 is used to sieve out the seeds after seed dressing upward. An elevating member 83 for driving the sieve ring 82 to lift and lower is provided on the outer ring 5. The seeder drives the rotating ring 6 to rotate evenly between the seed box 4 and the outer ring 5 through the driving member 7. Once the notch of the seed box 4 is aligned with the annular groove 61 of the rotating ring 6, several corn seeds in the seed box 4 will fall into the annular groove 61. When the seeds in the annular groove 61 of the rotating ring 6 move to the bottom outlet of the outer ring 5, the seeds will fall into the mixing cylinder 81 and be mixed with the seed dressing agent. Then, the elevating member 83 drives the sieve mesh 821 on the sieve ring 82 to sieve up the seeds mixed with the seed dressing agent. When the seeds on the sieve mesh 821 are lifted to the outlet 811 of the mixing cylinder 81, the seeds will slide down along the inclined sieve mesh 821 and slide out from the outlet 811 of the mixing cylinder 81, and finally fall onto the land. Under the operation and control of the user, the electric wheels 2 are used to drive the whole seeder to move forward evenly, so as to realize that the corn seeds mixed with the seed dressing agent can be evenly sown on the field and improve the efficiency of corn seeding.

[0028] As Figure 1 and Figure 2As shown in the figure, the driving member 7 includes a motor 71, a gear 72 and a toothed ring 73. A motor 71 is fixedly installed on one side of the frame 1. A gear 72 is fixedly connected to the output shaft of the motor 71. A toothed ring 73 is fixedly connected to the inner wall of the ring body on the side of the rotating ring 6 close to the motor 71. The gear 72 and the toothed ring 73 are meshed with each other. The motor 71 drives the toothed ring 73 and the rotating ring 6 to rotate through the meshing of the gear 72. The annular grooves 61 on the rotating ring 6 can be aligned with the notches of the seed box 4 in sequence, so that the corn seeds in the seed box 4 can intermittently fall into the annular grooves 61 of each rotating ring 6. The annular grooves 61 of the rotating ring 6 can intermittently carry the corn seeds and fall into the mixing cylinder 81.

[0029] As Figure 4 and Figure 5 As shown in the figure, the lifting member 83 includes a first cylinder 831, a first connecting rod 832 and a first magnet 833. A first cylinder 831 is fixedly installed on the outer side of the outer ring 5. The telescopic rod of the first cylinder 831 faces downward and is fixedly connected to a first connecting rod 832. A first magnet 833 is assembled at the rod end of the first connecting rod 832. A second magnet 834 is assembled on the side of the screening ring 82 close to the first magnet 833. The first magnet 833 and the second magnet 834 have different magnetic poles. The first cylinder 831 drives the first magnet 833 on the first connecting rod 832 to reciprocate up and down, so that the first magnet 833 can drive the screening ring 82 to reciprocate up and down in the mixing cylinder 81 by adsorbing the second magnet 834, realizing that the corn seeds mixed with the seed dressing agent can automatically fall out from the seed outlet 811 of the mixing cylinder 81.

[0030] As Figure 2 , Figure 6 and Figure 7 As shown in the figure, a seed feeding mechanism 9 for auxiliary sowing is provided on the outer ring 5 close to the seed dressing mechanism 8. The seed feeding mechanism 9 includes a second cylinder 91, a second connecting rod 92 and a seed dropping cylinder 93. A second cylinder 91 is fixedly installed on the outer side of the outer ring 5. The telescopic rod of the second cylinder 91 faces downward and is fixedly connected to a second connecting rod 92. A seed dropping cylinder 93 is fixedly installed at the rod end of the second connecting rod 92. A docking groove 931 for cooperating with the seed outlet 811 is provided on the side of the cylinder wall of the seed dropping cylinder 93 close to the mixing cylinder. The docking groove 931 of the seed dropping cylinder 93 is in sliding contact with the mixing cylinder 81. A soil breaking member 10 for breaking soil for sowing is provided at the bottom of the seed dropping cylinder 93. When the docking groove 931 of the seed dropping cylinder 93 is aligned with the seed outlet 811 of the mixing cylinder 81, the corn seeds mixed with the seed dressing agent slide from the seed outlet 811 of the mixing cylinder 81 into the seed dropping cylinder 93 and fall into the soil breaking member 10 at the bottom of the seed dropping cylinder 93. Cooperating with the second cylinder 91 to drive the seed dropping cylinder 93 to descend through the second connecting rod 92 and make the soil breaking member 10 insert into the soil layer for sowing, and finally release the seeds inside into the soil through the soil breaking member 10 to complete sowing.

[0031] As Figure 6 and Figure 8As shown in the figure, the soil-breaking part 10 includes a conical flap 101 and a motor 102. The bottom of the barrel of the seed sowing tube 93 is a through port. The conical flap 101 is circumferentially and rotatably connected to the bottom through port of the seed sowing tube 93. The conical flap 101 forms a pointed cone block at the bottom of the seed sowing tube 93. A plurality of motors 102 are fixedly installed at intervals in the circumferential direction at the bottom of the barrel of the seed sowing tube 93. The output shaft of the motor 102 is connected to the rotating shaft of the corresponding conical flap 101. Driven by the second cylinder 91, the seed sowing tube 93 descends, so that the closed conical flap 101 inserts corresponding sowing soil grooves in the soil. Then, the motor 102 is activated to drive the conical flap 101 to rotate and unfold at the bottom of the seed sowing tube 93, so that the corn seeds falling into the conical flap 101 can fall into the sowing soil grooves in the soil, thus realizing the automatic soil-breaking sowing of corn seeds.

[0032] As Figure 7 and Figure 8 shown in the figure, a first sensor 11 is assembled on one side of the upper barrel of the mixing barrel 81. The first sensor 11 is used to monitor whether seeds fall into the mixing barrel 81. The first sensor 11 has a built-in controller electrically connected to the first cylinder 831. The first sensor 11 can control the working state of the first cylinder 831 through the controller. When the first sensor 11 monitors that a batch of seeds fall into the mixing barrel 81, the first sensor 11 controls the first cylinder 831 to complete a lifting action through the controller, so that the seeds mixed with the seed dressing agent in the mixing barrel 81 can be lifted by the sieve mesh 821 and slide out from the seed outlet 811. A second sensor 111 is assembled in the docking groove 931 of the seed sowing tube 93. The second sensor 111 is used to monitor whether seeds enter the seed sowing tube 93. The second sensor 111 has a built-in controller electrically connected to the second cylinder 91. The second sensor 111 can control the working state of the second cylinder 91 through the controller. When the second sensor 111 monitors that a batch of seeds fall into the seed sowing tube 93 through the docking groove 931, the second sensor 111 controls the second cylinder 91 to complete a lifting action through the controller, so that the seed sowing tube 93 drives the soil-breaking part 10 to be inserted into the soil. When the telescopic rod of the second cylinder 91 extends to the maximum stroke, the preset program controls the soil-breaking part 10 to automatically open and release the seeds to complete sowing.

[0033] When using this seeder to sow fruit corn, first add corn seeds into each seed box 4 in advance through the feeding port 42. After starting the seeder, the user holds the operation handle 3 by hand and controls the electric wheel 2 to move forward at a constant speed. The frame 1 drives the overall structure to move stably. When the seeder moves to the sowing field, the motor 71 is enabled. The motor 71 drives the gear 72 to rotate through the output shaft. The gear 72 meshes with the toothed ring 73 on the inner wall of the rotating ring 6, driving all the rotating rings 6 to rotate synchronously and uniformly. When the annular groove 61 of the rotating ring 6 is briefly aligned with the notch at the lower part of the seed box 4, the corn seeds fall into the annular groove 61 of the rotating ring 6 under the action of gravity. Subsequently, the rotating ring 6 continues to rotate. When the rotating ring 6 continues to carry the seeds to the opening position at the bottom of the outer ring 5, the seeds fall vertically into the mixing cylinder 81 after separating from the annular groove 61. The seeds are mixed with the powdery seed dressing agent pre-stored in the cylinder. During this process, once the sensor 11 on the upper part of the mixing cylinder 81 detects the seeds falling in, it immediately triggers the cylinder 831 to complete a lifting action through the controller, that is, the telescopic rod of the cylinder 831 drives the connecting rod 832 and the magnet 833 to move upward. Since the magnet 833 and the magnet 834 on the side of the sieve ring 82 attract each other with opposite poles, the sieve ring 82 is pulled to lift along the inner wall of the mixing cylinder 81. When the mixed seeds with powdery seed dressing agent are screened out by the sieve mesh 821 on the sieve ring 82 during the lifting process, when the inclined sieve mesh 821 of the sieve ring 82 screens the dressed seeds upward to the seed outlet 811 of the mixing cylinder 81, the seeds slide out of the seed outlet 811 of the mixing cylinder 81 along the inclined sieve mesh 821. Subsequently, the sieve mesh 821 on the sieve ring 82 resets and waits for the subsequent seeds to fall. At the same time, the dressed seeds enter the seeding cylinder 93 through the docking groove 931 from the seed outlet 811 and will fall inside the closed conical flap 101. The sensor 111 in the docking groove 931 detects the passage of the seeds and immediately triggers the cylinder 91 to complete a telescopic action through the controller, that is, the telescopic rod of the cylinder 91 drives the connecting rod 92 and the seeding cylinder 93 to press down vertically until the closed conical flap 101 at the bottom of the seeding cylinder 93 is inserted into the soil layer under the thrust of the cylinder 91 to form a seeding groove. And when the telescopic rod of the cylinder 91 extends and reaches the maximum stroke, the motor 102 is started through a preset program. The motor 102 drives the corresponding conical flap 101 to rotate and unfold, so that the seeds in the conical flap 101 at the bottom of the seeding cylinder 93 are released into the seeding groove in the soil layer. Subsequently, during the process of the cylinder 91 retracting and driving the seeding cylinder 93 to rise, the dug soil will fall back into the seeding groove to cover the seeds. The motor 102 drives the corresponding conical flap 101 to gradually reset and close until the docking groove 931 of the seeding cylinder 93 resets and aligns with the seed outlet 811 of the mixing cylinder 81, and the cylinder 91 completes a triggering action, thus completing the seeding operation of a batch of corn seeds. Subsequently, repeat the above seeding actions and cooperate with the seeder to move forward at a constant speed, so that the corn seeds can be evenly sown on the land after being dressed with the seed dressing agent, improving the germination rate of fruit corn.

[0034] Example 2: On the basis of Example 1, as Figure 6 and Figure 8 shown, a fertilizing mechanism 12 for fertilizing is provided on one side of the bottom of the seed dropping cylinder 93. The fertilizing mechanism 12 includes a fertilizer cylinder 121 fixedly connected to one side of the bottom of the seed dropping cylinder 93. The fertilizer cylinder 121 is filled with granular corn fertilizer. An air pump 122 is fixedly installed on the outer wall of the fertilizer cylinder 121. The air pump 122 is connected to the inside of the fertilizer cylinder 121 through a pipeline. The bottom of the fertilizer cylinder 121 is a conical opening 123. A check valve 124 for releasing fertilizer is provided at the outlet of the conical opening 123. The fertilizer cylinder 121 will be inserted into the soil synchronously with the seed dropping cylinder 93. When the telescopic rod of the second cylinder 91 extends to the maximum stroke, a preset program controls the air pump 122 to charge a section of high-pressure air into the fertilizer cylinder 121, so that the high-pressure air briefly opens the check valve 124, enabling the corn fertilizer in the fertilizer cylinder 121 to be added to the soil layer near the corn seeds, and completing the corresponding initial fertilization while sowing the corn.

[0035] As Figure 1 , Figure 2 and Figure 9 shown, a watering mechanism 13 for watering after sowing is provided at the rear side of the frame 1. The watering mechanism 13 includes a water tank 131 fixedly installed at the rear side of the frame 1. A water pump 132 is installed in the water tank 131. A plurality of downwardly directed water outlet pipes 133 are provided at the front side of the water tank 131. The number of the water outlet pipes 133 is the same as that of the seed boxes 4. Sprayers 134 are installed at the water outlets of the water outlet pipes 133. The outlet of the water pump 132 is connected to each water outlet pipe 133 through a connecting pipe 135. After the seeder completes the sowing and fertilization of the corn seeds, the water pump 132 pumps the water in the water tank 131 into the water outlet pipes 133 at high pressure, and then sprays the water onto the sown soil through the plurality of sprayers 134, realizing the initial watering of the sown corn.

[0036] During the process of the soil-breaking part 10 at the bottom of the seeding cylinder 93 sowing corn seeds downward, that is, when the telescopic rod of the second cylinder 91 extends to the maximum stroke, the fertilizer cylinder 121 at the bottom of the seeding cylinder 93 will also be inserted into the soil layer synchronously. At this time, the air pump 122 is triggered through a preset program to inject a short-term high-pressure air flow into the fertilizer cylinder 121. The high-pressure air flow passes through the granular fertilizer inside the fertilizer cylinder 121 and then flushes open the check valve 124 at the bottom, so that the granular fertilizer is evenly scattered into the soil layer around the seeds through the conical opening 123. The check valve 124 then closes to prevent soil backflow, realizing the fertilization operation while sowing the seeds. After the seeding machine completes the seeding and fertilization operations, the water pump 132 in the water tank 131 is immediately started. The water pump 132 pressurizes the water in the water tank 131 and transports it to the water outlet pipes 133 everywhere through the connecting pipe 135. The water flow in the water outlet pipes 133 sprays out from the corresponding nozzles 134 and forms a fan-shaped water curtain, evenly covering the surface soil of the sowing area and completing the first watering after sowing. Thus, the seeding machine forms a closed-loop operation chain of "seeding - soil-breaking - fertilization - backfilling - watering", significantly improving the seeding efficiency of corn seeds and the survival rate of seedlings.

[0037] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
