Description

Technical Field

[0001] This invention relates to the field of corn planting technology, specifically to a seedling raising device for corn planting. Background Technology

[0002] Sowing and seedling raising are crucial for corn cultivation. Mastering the appropriate sowing time and improving sowing quality are essential for achieving higher yields and economic benefits. Using suitable sowing techniques can bring fresh corn to market earlier. Combining seedling raising and transplanting with direct sowing, based on planting objectives, soil conditions, and climate characteristics, can adjust the sowing period and increase profits.

[0003] Existing corn seedling raising devices typically use a seedling cart to slide out corn seeds during sowing and seedling raising.

[0004] However, this type of seeding device does not distribute corn seeds evenly. There may be a phenomenon where one group of seeds is distributed quickly while another group is distributed slowly, or where the distribution is sometimes fast and sometimes slow. Therefore, there is a need to provide a seedling raising device for corn planting, which aims to solve the above problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a seedling raising device for corn planting, so as to solve the problems in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A seedling raising device for corn planting, comprising:

[0008] Seedling cart;

[0009] The feeding unit, installed inside the seedling vehicle, is used to absorb corn kernels;

[0010] The feeding unit is rotatably connected inside the seedling cart and is connected to the clamping unit, which is used to drive the clamping unit to rotate inside the seedling cart;

[0011] The sliding unit is slidably connected inside the seedling cart and connected to the feeding unit, and is used to drive the feeding unit to slide.

[0012] The positioning unit, installed on the seedling cart and connected to the sliding unit, is used to position the sliding unit.

[0013] The reset unit is mounted on the sliding unit and connected to the positioning unit, and is used to drive the sliding unit to reset.

[0014] The feeding unit, installed on the seedling vehicle, is used to distribute the corn kernels after they have been fed in.

[0015] Compared with the prior art, the embodiments of the present invention have the following beneficial effects: The present invention sets up a feeding unit, which is rotatably connected inside the seedling cart and connected to the clamping unit, for driving the clamping unit to rotate inside the seedling cart; a sliding unit, which is slidably connected inside the seedling cart and connected to the feeding unit, for driving the feeding unit to slide; a positioning unit, which is installed on the seedling cart and connected to the sliding unit, for positioning the sliding unit; a reset unit, which is installed on the sliding unit and connected to the positioning unit, for driving the sliding unit to reset; and a distributing unit, which is installed on the seedling cart, for distributing the corn kernels after feeding.

[0016] When sowing corn, the corn seeds are first introduced into the clamping unit. The clamping unit is then activated, adsorbing the corn seed particles. The sliding unit is then activated, causing the feeding unit to rotate. This rotates the clamping unit above the distributing unit, facilitating the corn seed particles to slide into the distributing unit. The feeding unit is positioned by a positioning unit, improving the stability of the falling corn seeds. The reset unit is then activated, resetting the positioning unit and causing the feeding unit to rotate in the opposite direction, allowing the clamping unit to adsorb the corn seed particles again. This cycle is repeated, allowing the distributing unit to sequentially distribute the corn seed particles. This facilitates the orderly and quantitative sowing of two groups of corn seeds for seedling cultivation.

[0017] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0027] See Figures 1-6 A seedling raising device for corn planting, comprising:

[0028] Seedling truck 1;

[0029] The clamping unit 2 is installed inside the seedling vehicle 1 and is used to adsorb corn kernels;

[0030] The feeding unit 3 is rotatably connected inside the seedling cart 1 and connected to the clamping unit 2, and is used to drive the clamping unit 2 to rotate inside the seedling cart 1;

[0031] The sliding unit 4 is slidably connected inside the seedling cart 1 and connected to the feeding unit 3, and is used to drive the feeding unit 3 to slide.

[0032] The positioning unit 5 is installed on the seedling cart 1 and connected to the sliding unit 4, and is used to position the sliding unit 4.

[0033] The reset unit 6 is mounted on the sliding unit 4 and connected to the positioning unit 5, and is used to drive the sliding unit 4 to reset.

[0034] The feeding unit 7 is installed on the seedling vehicle 1 and is used to feed the corn kernels after they have been fed.

[0035] In an embodiment of the present invention, when sowing corn, the corn seeds are first introduced into the clamping unit 2, and the clamping unit 2 is activated to adsorb the corn seed particles. The sliding unit 4 is then activated, causing the feeding unit 3 to rotate. This allows the feeding unit 3 to rotate the clamping unit 2 above the distributing unit 7, facilitating the corn seed particles to slide into the distributing unit 7. The feeding unit 3 is positioned by the positioning unit 5, improving the stability of the falling corn seed particles. The reset unit 6 is then activated, resetting the positioning unit 5. This causes the feeding unit 3 to rotate the clamping unit 2 in the opposite direction, allowing the clamping unit 2 to adsorb the corn seed particles again. This process is repeated, allowing the distributing unit 7 to sequentially distribute the corn seed particles. This facilitates the sequential, orderly, and quantitative sowing and seedling cultivation of two groups of corn seeds.

[0036] In one embodiment of the present invention, such as Figure 1 As shown, the clamping unit 2 includes:

[0037] The feeding box 21 is installed inside the seedling cart 1, and a push plate 24 is slidably connected inside it. The push plate 24 is connected to the inner wall of the feeding box 21 via an electric telescopic rod 25.

[0038] An air pump 22 is installed inside the seedling cart 1, and the output end of the air pump 22 is connected to a suction tube 23.

[0039] In this embodiment, the feeding box 21 is installed inside the seedling cart 1, and a push plate 24 is slidably connected inside. The push plate 24 is connected to the inner wall of the feeding box 21 via an electric telescopic rod 25. The air pump 22 is installed inside the seedling cart 1, and a suction pipe 23 is connected to the output end of the air pump 22. The seedling cart 1 has a feeding port at the top.

[0040] Sowing and seedling raising are key to corn cultivation. Mastering the appropriate sowing time and improving sowing quality are essential to achieving higher yields and economic benefits.

[0041] When planting corn, the corn seeds are first introduced into the feeding box 21 through the inlet. The air pump 22 is then turned on, and its output end causes the suction tube 23 to generate suction, allowing the end of the suction tube 23 to adsorb the corn seeds, with each end of the suction tube 23 adsorbing just one corn seed. After the corn seeds in the feeding box 21 have been gradually adsorbed, the electric telescopic rod 25 is activated. The electric telescopic rod 25 drives the push plate 24 to slide within the feeding box 21. The push plate 24 moves the corn seeds, maintaining them at a certain height within the feeding box 21, facilitating the adsorption of corn seeds by the suction tube 23.

[0042] The end of the straw 23 can be provided with an arc-shaped groove to facilitate the adsorption of corn seeds.

[0043] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the feeding unit 3 includes:

[0044] The fixing frame 31 is installed inside the seedling cart 1, and its surface is provided with vertical grooves 32 and horizontal grooves 33.

[0045] An arc-shaped groove 34 is formed on a fixed frame 31, with its two ends connected to a vertical groove 32 and a horizontal groove 33 respectively, and a first sliding column 35 and a second sliding column 36 are slidably connected inside.

[0046] The L-shaped frame 38 is installed on the side of the first sliding column 35 and the second sliding column 36, and its end is connected to the suction tube 23;

[0047] The slide bar 37 is slidably connected within the transverse groove 33.

[0048] In this embodiment, the fixing frame 31 is installed inside the seedling cart 1, and its surface is provided with vertical grooves 32 and horizontal grooves 33; the arc-shaped groove 34 is opened on the fixing frame 31, and its two ends are respectively connected to the vertical grooves 32 and horizontal grooves 33, and the first sliding column 35 and the second sliding column 36 are slidably connected inside; the L-shaped frame 38 is installed on the side of the first sliding column 35 and the second sliding column 36, and its end is connected to the suction tube 23; the sliding rod 37 is slidably connected in the horizontal groove 33.

[0049] When the sliding unit 4 is activated, the sliding unit 4 can drive the slide rod 37 to slide within the transverse groove 33.

[0050] When the sliding rod 37 slides to the left in the horizontal groove 33, the sliding rod 37 can drive the second sliding column 36 to slide to the left in the horizontal groove 33 through the connection of the second sliding column 36. Therefore, the second sliding column 36 can drive the first sliding column 35 to slide to the left in the horizontal groove 33 synchronously through the fixing frame 31 until the first sliding column 35 slides into the arc groove 34 and the vertical groove 32 in sequence. When the first sliding column 35 slides into the vertical groove 32, the L-shaped frame 38 will rotate with the first sliding column 35. Thus, the L-shaped frame 38 will rotate clockwise under the action of the first sliding column 35, so that the L-shaped frame 38 can drive the suction tube 23 on its side to rotate synchronously until the suction tube 23 rotates to the top of the dispensing unit 7. At this time, the air pump 22 is turned off, so the corn seeds adsorbed at the end of the suction tube 23 can fall freely and fall into the dispensing unit 7, so that the corn seeds can be dispensed under the action of the dispensing unit 7.

[0051] After the corn seeds at the end of the straw 23 are dispensed, the slide bar 37 can slide to the right within the horizontal groove 33. At this time, the first sliding column 35 will slide downward within the vertical groove 32 under the action of the gravity of the L-shaped frame 38, and will slide sequentially into the arc groove 34 and the horizontal groove 33, until the L-shaped frame 38 slides to a horizontal state (e.g., Figure 2 As shown in the figure, at this time, the L-shaped frame 38 can drive the suction tube 23 to slide into the feeding box 21, and the air pump 22 can be turned on again, so that the end of the suction tube 23 can be adsorbed again.

[0052] A compression spring can also be installed in the vertical groove 32 of the feeding unit 3, so that the first sliding column 35 can slide in the vertical groove 32 under the push of the compression spring.

[0053] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the sliding unit 4 includes:

[0054] The first fixing plate 41 is fixed on the seedling cart 1 and is slidably connected to the slide bar 37;

[0055] The connecting bracket 42 is connected to the surface of the slide bar 37 and is connected to the side of the first fixing plate 41 through the elastic member 43;

[0056] The second fixing plate 44 is fixed inside the seedling cart 1, and a telescopic component 45 is installed on the side. The telescopic component 45 is connected to the sliding rod 37 through the positioning unit 5.

[0057] In this embodiment, the first fixing plate 41 is fixed on the seedling cart 1 and slidably connected to the slide rod 37; the connecting frame 42 is connected to the surface of the slide rod 37 and is connected to the side of the first fixing plate 41 through the elastic member 43; the second fixing plate 44 is fixed inside the seedling cart 1 and has a telescopic member 45 installed on its side, and the telescopic member 45 is connected to the slide rod 37 through the positioning unit 5.

[0058] When the telescopic component 45 is opened, the telescopic component 45 can drive the sliding rod 37 to slide to the left within the first fixed plate 41 via the positioning unit 5. During the sliding process, the sliding rod 37 can drive the connecting frame 42 to compress the elastic component 43, so that the end of the sliding rod 37 can drive the second sliding column 36 to slide within the horizontal groove 33, thereby allowing the first sliding column 35 to slide into the vertical groove 32, making it easier for the suction tube 23 to guide the corn seeds it has absorbed into the dispensing unit 7.

[0059] After the corn seeds are processed, the telescopic component 45 retracts, so the connecting frame 42 can drive the slide rod 37 to slide in the opposite direction (to the right) within the first fixed plate 41 and the transverse groove 33 under the push of the elastic component 43, thus facilitating the L-shaped frame 38 to slide back to the horizontal direction.

[0060] The elastic element 43 can be a spring or elastic rubber, which can be used to push the slide rod 37 to slide within the first fixed plate 41 via the connecting frame 42.

[0061] In one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the positioning unit 5 includes:

[0062] The tapered bracket 51 is mounted on the surface of the slide bar 37;

[0063] The bracket 53 is fixed on the seedling cart 1, and the side is connected to the sliding part 52 via the elastic airbag 54.

[0064] The first inclined groove 521 is formed on the side of the slider 52 and is slidably connected to the side of the tapered frame 51.

[0065] In this embodiment, the conical frame 51 is mounted on the surface of the slide bar 37; the bracket 53 is fixed on the seedling cart 1, and a sliding member 52 is connected to its side via an elastic airbag 54; the first inclined groove 521 is formed on the side of the sliding member 52 and is slidably connected to the side of the conical frame 51.

[0066] The sliding rod 37 slides to the left within the first fixed plate 41, causing the conical frame 51 on its surface to slide synchronously until the conical frame 51 slides to contact the first inclined groove 521 on the side of the sliding member 52. Therefore, the first inclined groove 521 can drive the two sets of sliding members 52 to slide upward and downward respectively under the compression of the conical frame 51. The sliding members 52 can compress the elastic airbag 54 until the conical frame 51 slides to the left side of the sliding member 52.

[0067] When the conical frame 51 slides to the left side of the sliding member 52, the two sets of sliding members 52 can be reset (sliding in the opposite direction) under the elastic force of the elastic airbag 54, so that the two sets of sliding members 52 can slide to the right side of the conical frame 51. Therefore, the conical frame 51 can be positioned under the action of the two sets of sliding members 52, which in turn can position the sliding rod 37, and then position the L-shaped frame 38 and the suction tube 23. This improves the stability of the suction tube 23 after rotation, and makes it easier for the corn seeds adsorbed at the end of the suction tube 23 to fall stably into the dispensing unit 7.

[0068] The elastic airbag 54 in the positioning unit 5 can also be replaced by a spring sheet, which is convenient for pushing the sliding member 52 to reset. This is not the only limitation.

[0069] In one embodiment of the present invention, such as Figure 2 , Figure 3 and Figure 4 As shown, the reset unit 6 includes:

[0070] U-shaped frame 61 is installed inside the seedling cart 1, and guide rod 62 is installed inside it;

[0071] The slider 65 is slidably connected to the guide rod 62, and a second inclined groove 651 is provided on its side.

[0072] A threaded rod 63 is rotatably connected to a U-shaped frame 61, and a reverse thread is installed on its surface. The threaded rod 63 is connected to two sets of sliders 65 through the thread.

[0073] Motor 64 is mounted on the side of U-shaped frame 61, and the end of threaded rod 63 is connected to the output end of motor 64;

[0074] The third inclined groove 66 is formed on the sliding member 52 and is slidably connected to the second inclined groove 651.

[0075] In this embodiment, the U-shaped frame 61 is installed inside the seedling cart 1, and a guide rod 62 is installed inside; the slider 65 is slidably connected to the guide rod 62, and a second inclined groove 651 is opened on the side; the threaded rod 63 is rotatably connected to the U-shaped frame 61, and a reverse thread is installed on its surface; the threaded rod 63 is connected to two sets of sliders 65 through the thread; the motor 64 is installed on the side of the U-shaped frame 61, and the end of the threaded rod 63 is connected to the output end of the motor 64; the third inclined groove 66 is opened on the slider 52 and is slidably connected to the second inclined groove 651.

[0076] When it is necessary to adsorb corn seeds again, the motor 64 is turned on. The output end of the motor 64 can drive the threaded rod 63 on its surface to rotate, so that the threaded rod 63 can drive the slider 65 on its surface to slide in the opposite direction on the guide rod 62, so that the two sets of sliders 65 can move away from each other. After the two sets of sliders 65 move away from each other, the telescopic component 45 is turned on again. The telescopic component 45 can drive the U-shaped frame 61, the guide rod 62 and the two sets of sliders 65 to slide synchronously until the two sets of sliders 65 contact the third inclined groove 66. Therefore, the third inclined groove 66 can push the two sets of sliding components 52 to compress the elastic airbag 54 under the push of the two sets of sliders 65. Until both sets of sliding parts 52 slide to the side of the conical frame 51, the connecting frame 42 can drive the sliding rod 37 to slide to the right in the first fixed plate 41 under the push of the elastic part 43 until the L-shaped frame 38 slides to the horizontal direction, and the L-shaped frame 38 drives the suction tube 23 to slide into the feeding box 21, so that the suction tube 23 can absorb the corn seeds again.

[0077] When it is necessary to re-dispense the corn seeds adsorbed at the end of the straw 23, the motor 64 is turned on, causing the threaded rod 63 to rotate in the opposite direction. This allows the two sets of sliders 65 to come closer together. After the two sets of sliders 65 come into contact, the telescopic component 45 is activated again, allowing the telescopic component 45 to drive the U-shaped frame 61, the guide rod 62, and the two sets of sliders 65 to slide synchronously until the two sets of sliders 65 come into contact with the end of the sliding rod 37. Therefore, the sliding rod 37 can slide to the left in the horizontal groove 33 under the push of the two sets of sliders 65. This allows the end of the sliding rod 37 to drive the second sliding column 36 to slide in the horizontal groove 33, thereby allowing the first sliding column 35 to slide into the vertical groove 32, making it easier for the straw 23 to guide the adsorbed corn seeds into the dispensing unit 7.

[0078] The third inclined groove 66 in the reset unit 6 can also be replaced by an arc-shaped groove, which can facilitate the sliding member 52 to compress the elastic airbag 54 under the push of the second inclined groove 651. This is not the only limitation.

[0079] In one embodiment of the present invention, such as Figure 5 As shown, the material distribution unit 7 includes:

[0080] The material distribution rack 71 is installed inside the seedling cart 1, and the surface is provided with a material distribution trough 72.

[0081] The first triangular groove 73 is opened on the material distribution rack 71 and is connected to the material distribution groove 72;

[0082] The second triangular groove 74 is provided on the material distribution rack 71 and is connected to the first triangular groove 73;

[0083] The discharge pipe 75 is installed on the material distribution rack 71, and there are two sets of them, which are respectively connected to the bottom ends of the second triangular groove 74;

[0084] The rotating shaft 76 is rotatably connected in the second triangular groove 74, and a guide frame 77 is mounted on its surface.

[0085] In this embodiment, the material distribution rack 71 is installed inside the seedling cart 1, and a material distribution groove 72 is formed on its surface; the first triangular groove 73 is formed on the material distribution rack 71 and communicates with the material distribution groove 72; the second triangular groove 74 is formed on the material distribution rack 71 and communicates with the first triangular groove 73; the discharge pipe 75 is installed on the material distribution rack 71, and two sets are installed, which are respectively connected to the bottom ends of the second triangular groove 74; the rotating shaft 76 is rotatably connected inside the second triangular groove 74, and a guide frame 77 is installed on its surface.

[0086] When the corn seeds slide into the distribution trough 72, they can flow into the first triangular trough 73 and pass through the side (right side) of the guide frame 77 to the second triangular trough 74. When the corn seeds slide into the second triangular trough 74, they can be discharged through the discharge pipe 75 on the right side of the second triangular trough 74.

[0087] When the corn seed passes through the lower side of the guide frame 77, the lower side of the guide frame 77 is squeezed by the weight of the corn seed, so the guide frame 77 can drive the rotating shaft 76 to rotate to the right in the second triangular groove 74 until the right side of the guide frame 77 rotates to contact the right side of the second triangular groove 74. At this time, a new channel is formed between the left side of the guide frame 77 and the inner wall of the second triangular groove 74.

[0088] When another corn seed slides into the feeding trough 72, it can then slide into the first triangular trough 73 and, via the left side of the guide frame 77, into the left side of the second triangular trough 74. Therefore, the corn seed can be discharged through the discharge pipe 75 on the left side of the second triangular trough 74. Similarly, during this process, the guide frame 77 rotates to the left under the push of the corn seed, repeating the above process. This allows the corn seeds to alternately slide out from the two sets of discharge pipes 75, facilitating sequential sowing and seedling cultivation.

[0089] The lower inner side of the second triangular groove 74 in the material distribution unit 7 can be set as a raised arc surface or a slope surface, so that the corn seeds can slide out from the two sets of discharge pipes 75.

[0090] The working principle of this invention is as follows: When sowing corn, the corn seeds are first introduced into the feeding box 21 through the inlet. The air pump 22 is then turned on, and the output end of the air pump 22 causes the suction tube 23 to generate suction, so that the end of the suction tube 23 can adsorb the corn seeds, and the end of the suction tube 23 can just adsorb one corn seed. After the corn seeds in the feeding box 21 are gradually adsorbed, the electric telescopic rod 25 is activated. The electric telescopic rod 25 can drive the push plate 24 to slide within the feeding box 21. The push plate 24 can push the corn seeds to move. Through the movement of the push plate 24, the corn seeds in the feeding box 21 can be kept at a certain height, which facilitates the adsorption of corn seeds by the suction tube 23.

[0091] When the sliding unit 4 is activated, the sliding unit 4 can drive the slide rod 37 to slide within the transverse groove 33. When the sliding rod 37 slides to the left in the horizontal groove 33, the sliding rod 37 can drive the second sliding column 36 to slide to the left in the horizontal groove 33 through the connection of the second sliding column 36. Therefore, the second sliding column 36 can drive the first sliding column 35 to slide to the left in the horizontal groove 33 synchronously through the fixing frame 31 until the first sliding column 35 slides into the arc groove 34 and the vertical groove 32 in sequence. When the first sliding column 35 slides into the vertical groove 32, the L-shaped frame 38 will rotate with the first sliding column 35. Thus, the L-shaped frame 38 will rotate clockwise under the action of the first sliding column 35, so that the L-shaped frame 38 can drive the suction tube 23 on its side to rotate synchronously until the suction tube 23 rotates to the top of the dispensing unit 7. At this time, the air pump 22 is turned off, so the corn seeds adsorbed at the end of the suction tube 23 can fall freely and fall into the dispensing unit 7, so that the corn seeds can be dispensed under the action of the dispensing unit 7.
