Description

Technical Field

[0001] The invention relates to the technical field of agricultural sowing, and in particular to a peanut sowing and fertilizing device for agricultural planting. Background Art

[0002] As an important oil crop and cash crop widely grown around the world, peanuts play a pivotal role in agricultural production and the food industry. In addition, peanut planting can improve soil structure and increase soil fertility, which is of great significance for achieving sustainable agricultural development.

[0003] At present, the common methods for planting peanuts include flat cultivation, ridge cultivation, and intercropping with wheat, and each method is suitable for different regions. The existing peanut sowing device, such as Chinese patent announcement No. CN213152850U, discloses a peanut sowing device for agricultural planting. The sowing device can not only sow five rows at the same time, but also has high sowing efficiency. In addition, the output shaft of the first motor drives the rotating rod to rotate, and the rotating rod drives the rotation to intermittently block the falling of peanuts, so that the peanuts fall evenly and the sowing spacing is uniform. The brush arranged on the periphery of the circular plate can prevent the peanuts from being crushed when the circular plate rotates, so as to ensure the planting efficiency of the peanut seeds.

[0004] Although this sowing method improves the sowing efficiency, it is still necessary to apply fertilizer after sowing. In addition, since the base fertilizer is the main source of nutrients in the early growth stage of peanuts, the traditional method of applying base fertilizer is mainly through manual spreading or simple mechanical fertilization. The distribution of fertilizer in the soil is often uneven. In some areas, there is too much fertilizer, which can easily cause seed and root burns, while in some areas, there is insufficient fertilizer, which affects the normal growth of peanuts.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 11 The present invention provides a technical solution: a peanut sowing and fertilizing device for agricultural planting, comprising a mounting tube 1 mounted on a traveling machine through a fixing frame, and the mounting tube 1 can be adjusted vertically, and also includes:

[0039] Two telescopic arms are respectively installed on both sides of the installation tube 1 and can be rotated and adjusted, and the bottom ends of the two telescopic arms are installed with a soil-moving shovel 6. When the two telescopic arms rotate, the two soil-moving shovels 6 can move the surface soil to both sides or to the middle;

[0040] A lifting rod 2 is installed in the installation tube 1 and can slide vertically and adjustably. Two arc-shaped shovels 11 that can rotate and adjust are installed at the bottom of the lifting rod 2. When the two arc-shaped shovels 11 rotate relative to each other, the soil below can be gathered into them.

[0041] A fertilization channel is installed on the outer wall of the arc shovel 11, and the fertilization channel can apply fertilizer to the gap between the arc shovel 11 and the pit below;

[0042] A seed dropping channel is provided in the lifting rod 2 , and the seed dropping channel can drop seeds onto the soil above the two arc-shaped shovels 11 .

[0043] At present, there are two methods for sowing peanuts, such as double-grain drill sowing, single-grain drill sowing, small cluster hole sowing, wide-narrow row sowing, wide-row narrow-plant sowing and the like. This embodiment mainly improves the hole sowing method. As the main nutrient source of peanuts in the early growth period, basal fertilizer usually accounts for 60% to 70% of the total amount of fertilizer applied during the entire growth period. Therefore, the method and amount of fertilization will play an important role in the subsequent growth of peanuts.

[0044] Generally, the method of basal fertilizer can be carried out at the same time as sowing, or sowing first and then fertilizing, or fertilizing first and then sowing. The subsequent two methods are not ideal. If sowing first and then fertilizing, it may cause uneven contact between fertilizer and seeds, and may even burn seeds or seedlings. Fertilizing first and then sowing may cause nutrient loss or volatilization, reducing fertilizer utilization rate. The method of sowing while fertilizing is more ideal. Therefore, in this embodiment, the two methods are carried out simultaneously to ensure that seeds can obtain sufficient nutrients in the early stages of germination and seedling growth, and promote early growth of strong seedlings. The specific implementation method is as follows:

[0045] See also Figure 2 and Figure 4 First, the soil to be sown is plowed and leveled, and then the installation cylinder 1 is moved to the sowing position by a traveling machine (either an existing tractor or a high-ground clearance machine can be used), and then the installation cylinder 1 is controlled to move vertically downward until the soil-moving shovel 6 is inserted into the surface layer of the soil below, and then the height position of the installation cylinder 1 is stopped and fixed. At this time, the two telescopic arms rotate to both sides under the drive of the external structure, and the soil-moving shovel 6 is used to move the surface soil to both sides. Figure 6 As shown, a preliminary pit is formed on the ground to prepare for subsequent fertilization;

[0046] Then the lifting rod 2 moves downward under the drive of the external structure, so that the two arc shovels 11 are connected with the soil at the bottom of the pit and inserted into the part, and then the two arc shovels 11 start to rotate and close under the external driving structure, inserting into the soil below, and gathering the soil in the middle between the two arc shovels 11, as shown in FIG. Figure 8 As shown, the lifting rod 2 then moves upward to form a gap between the arc-shaped shovel 11 and the pit below, and the fertilization channel can now apply the base fertilizer into the gap between the two, thus completing the fertilization process;

[0047] At the same time, the seed dropping channel in the lifting rod 2 also drops seeds above the soil in the two arc-shaped shovels 11, so that fertilization and seed dropping are carried out simultaneously, and then the two arc-shaped shovels 11 are controlled to rotate and open, and the soil inside them falls back into the pit below, so that the fertilizer can be applied just below the seeds, so as to achieve the purpose of deep application to the seeds, and the soil in the arc-shaped shovel 11 forms a soil isolation layer to ensure that the seeds and fertilizer are not in direct contact, avoiding seedling burn.

[0048] After fertilizing and sowing, the lifting rod 2 moves up and resets, and then the two telescopic arms swing to the middle, and the soil on both sides is pushed to the middle through the soil-moving shovel 6 to cover the seeds. At this point, the entire sowing process is completed. In this way, sowing and fertilizing are carried out at the same time, and the method of deep fertilization in the right position is adopted. There is no need to dig pits in advance, which not only saves working procedures, but also improves the utilization rate of fertilizers and ensures the early growth and development of seedlings.

[0049] It is worth mentioning that the distance that the two arc-shaped shovels 11 move upward after gathering the soil should not be too large, and a gap for fertilization can be formed. In this way, when the two arc-shaped shovels 11 are opened, it can prevent the fertilizer from being taken out of the pit, and it can also prevent the seeds and soil from being scattered due to the large height difference, ensure the integrity of the middle soil isolation layer, and prevent the seeds from direct contact with the fertilizer.

[0050] After sowing is completed, the traveling machine can move to the next location for sowing, and multiple devices can be designed side by side to carry out multi-row sowing to improve work efficiency.

[0051] In one of the more preferred embodiments, a method for feeding seeds is provided;

[0052] A through hole is provided at the center of the lifting rod 2, and an adjusting tube 10 is slidably installed on the lower half of the through hole, a lower seeding tube 9 connected with the adjusting tube 10 is installed on the upper half of the through hole, and the lower seeding tube 9 is connected with an external feeding device, and a connecting shaft 12 is rotatably installed through the bottom end of the adjusting tube 10, one of the arc-shaped shovels 11 is fixed to the connecting shaft 12, and the other arc-shaped shovel 11 is rotatably connected to the connecting shaft 12, a receiving cavity is provided at the center of the connecting shaft 12, and a material dropping trough 16 is provided on the outer wall, and the material dropping trough 16 can rotate with the connecting shaft 12 and be connected with the upper channel or the lower outlet of the adjusting tube 10.

[0053] For details, please refer to Figure 4 , Figure 5 and Figure 8 , wherein the seed placement tube 9 and the regulating tube 10 together form a seed drop channel, when the two arc-shaped shovels 11 are in the original state, that is, Figure 6 In the state shown, the drop groove 16 is connected to the upper channel of the regulating tube 10, so the seeds can fall into the receiving cavity of the connecting shaft 12 for storage;

[0054] When the two arc-shaped shovels 11 rotate and collect the soil therein, the connecting shaft 12 will rotate accordingly and connect the drop chute 16 with the lower outlet of the regulating tube 10, so that the seeds in the receiving chamber fall down. In this way, the seeds can fall down in the process of shoveling the soil and digging the hole, and the drop chute 16 is connected with the upper channel of the regulating tube 10 again when the arc-shaped shovels 11 are opened;

[0055] Moreover, the space of the receiving chamber can be controlled so that it can accommodate 2-4 seeds. In this way, not only can the seeds fall quantitatively, but also the soil height in the arc shovel 11 will not be higher than the height of the connecting shaft 12, so that the seeds can fall normally, and the vibration of the traveling machine itself can also promote the seeding.

[0056] In one of the more preferred embodiments, an electric slider 13 that can be vertically slid and adjusted is installed on the two support arms at the bottom of the lifting rod 2, and the electric slider 13 and the outer walls of the two arc-shaped shovels 11 are rotatably connected with a connecting rod 14, and the electric slider 13 is always located above the two arc-shaped shovels 11, and a slider structure is also provided between the adjusting tube 10 and the inner wall of the through hole in the lifting rod 2, and the slider structure can limit the sliding stroke of the adjusting tube 10 in the lifting rod 2.

[0057] As can be seen from the above content, the two arc-shaped shovels 11 need to move up a certain distance after rotating to gather the soil, so as to form a fertilization gap between them and the pit below. Therefore, the adjustment pipe 10 needs to have a certain displacement distance in the vertical direction. In this embodiment, the specific method is as follows:

[0058] See also Figure 4 and Figure 6 First, the electric slider 13 moves downward to adjust, which will first drive the two arc shovels 11 and the adjustment tube 10 to move downward for a distance through the connecting rod 14, so that the arc shovel 11 contacts the soil, until the slider structure limits the movement of the adjustment tube 10. At this time, the electric slider 13 continues to move downward, which will drive the two arc shovels 11 to rotate through the two connecting rods 14, so that they are inserted into the soil below and form a pit;

[0059] Then the electric slider 13 moves upward. At this time, due to the friction and adhesion between the soil and the arc shovel 11, the two arc shovels 11 are opened under the action of the connecting rod 14. Instead, they move upward as a whole, so that a fertilization gap is formed between the arc shovel 11 and the pit below, until the adjustment tube 10 moves upward to the limit position. At this time, the two arc shovels 11 will rotate and open under the action of the connecting rod 14, so that the soil and seeds inside them fall down;

[0060] This not only forms enough fertilization intervals, but also reserves enough material feeding time for fertilization to ensure the application of fertilizer;

[0061] It is worth mentioning that a reserved section is provided between the adjusting tube 10 and the seeding tube 9 to meet the moving stroke of the adjusting tube 10 in the vertical direction.

[0062] In one of the more preferred embodiments, a fertilization channel and a fertilization feeding implementation are provided;

[0063] The fertilization channel includes an outer covering pipe 21 fixed to the outer wall of the arc surface of the arc shovel 11, and also includes a feed pipe 19 installed in the lifting rod 2. The feed pipe 19 is connected to the outer covering pipe 21 through a soft pipe, and the top of the feed pipe 19 is connected to an external feeding device.

[0064] The fertilization channel also includes an air inlet pipe connected to the end of the feed conveying pipe 19, and the air inlet pipe is connected to an external air supply device.

[0065] For details, please refer to Figure 6 and Figure 7 The feeding pipe 19, the soft pipe and the outer covering pipe 21 together form a fertilization channel. When the two arc-shaped shovels 11 are in Figure 7 In the state shown, the soft tube is in a bent state, so that the fertilization channel is in an interrupted and closed state, and then when the arc-shaped shovel 11 rotates to shovel the soil, the soft tube is straightened from the bent state to make it connected;

[0066] Then, when the arc shovel 11 moves upward, the external air supply device supplies air to the conveying pipe 19 through the air inlet pipe, which can accelerate the falling of the fertilizer on the one hand, and on the other hand, when the arc shovel 11 is shoveled into the soil, the outlet of the outer tube 21 may be blocked by the soil, and the air flow can also spray out the blocked part of the soil to ensure the dredging of the fertilizer channel, thereby completing the fertilization process;

[0067] It is worth mentioning that the soft tube can also be in the form of a corrugated tube, so that it can be bent and have a certain expansion and contraction range, and a certain expansion and contraction space can be reserved for the arc shovel 11 when it rotates.

[0068] In one of the more preferred embodiments, an implementation method of the telescopic arm swinging is provided;

[0069] The telescopic arm includes a side wheel 3 rotatably mounted on a through groove on the side wall of the mounting tube 1, an extension tube 4 is fixed to the side wall of the side wheel 3, a telescopic plate 5 is slidably mounted on the inner wall of the extension tube 4, and a spring 17 is connected between the telescopic plate 5 and the inner wall of the extension tube 4, and an inclined soil-moving shovel 6 is mounted on the bottom end of the telescopic plate 5;

[0070] A slide groove is also provided on the side wall of the mounting tube 1 above the side wheel 3, and a slider 7 is vertically slidably installed in the slide groove, a winding wheel 8 is rotatably installed in the slider 7, a pull rope 18 is rotatably connected to the inner wall of the winding wheel 8, and one end of the pull rope 18 is inserted into the extension tube 4 from the groove provided on the side wheel 3, and is connected to the outer wall of the telescopic plate 5, and a clamping protrusion 20 is also formed on the outer wall of the lifting rod 2 below the slider 7.

[0071] The outer walls of the side wheel 3 and the winding wheel 8 are both provided with friction edges, and the protruding portion of the friction edge is provided with an inclined surface on one side and a vertical surface on the other side.

[0072] For details, please refer to Figure 6 and Figure 7 When the installation tube 1 is moved and adjusted to a suitable position, the two soil shovels 6 will be inserted into the soil to a certain depth. In the initial state, the lifting rod 2 is located at the top and under the action of the clamping protrusion 20, the slider 7 and the winding wheel 8 rotating thereon are also at the top position, and the winding wheel 8 will retract the telescopic plate 5 to a part of the extension tube 4 through the pull rope 18;

[0073] Then, the lifting rod 2 starts to move downward under the drive of the external structure, and at the same time, the slider 7 and the winding wheel 8 move downward together under the pulling force of the pull rope 18 until the winding wheel 8 contacts and rubs with the side wheel 3. Then, as the lifting rod 2 continues to move downward, it contacts and rubs with the side wheel 3 to drive the side wheel 3 to rotate outward. The rotation direction is as follows: Figure 6 As shown by the middle arrow, the telescopic plate 5 and the soil-moving shovel 6 are rotated outwards to move the soil in the middle to both sides;

[0074] Moreover, during this process, the reel 8 drives the reel 8 to rotate in the opposite direction, thereby reeling the pull rope 18. Therefore, the telescopic plate 5 and the soil-moving shovel 6 will gradually shrink into the extension tube 4 during the rotation process, so that the soil-moving shovel 6 can move the soil to both sides to form bulges on both sides, such as Figure 6 As shown by the dotted line in the middle, this is to prevent the soil from being pushed too far away and affecting the subsequent soil filling;

[0075] After the soil-moving shovel 6 is separated from the soil, the reel 8 rotates to make the pull rope 18 and its rotation connection point pass the tangent direction between its center and the center of the side wheel 3. At this time, under the elastic force of the spring 17, the reel 8 is pulled to continue to rotate, so that the section of the pull rope 18 wound on the reel 8 is released, so that the telescopic plate 5 and the soil-moving shovel 6 are extended again. This process is sufficient to make the soil-moving shovel 6 pass over the soil piles on both sides to prepare for the subsequent soil return.

[0076] Then, after the above-mentioned sowing and fertilizing are completed, the lifting rod 2 moves upward, driving the side wheel 3 to rotate in the opposite direction, so that the extension tube 4, the telescopic plate 5 and the soil-moving shovel 6 swing back together, thereby gathering the soil to the middle to cover the seeds and completing the final seed-burying process;

[0077] It is worth mentioning that, since the lifting rod 2 will pull the pull rope 18 during the upward movement, the telescopic plate 5 and the soil-moving shovel 6 will also shrink. However, it can be seen from the above content that the soil-moving shovel 6 will first be partially inserted into the soil when moving the soil to both sides, and when returning the soil, the soil-moving shovel 6 does not need to be inserted into the soil again. Therefore, the soil-moving shovel 6 shrinks when it is moved back and the soil can be gathered to the middle. Moreover, the two soil-moving shovels 6 do not need to be completely closed again, and a certain gap can be reserved in the middle to avoid interference with the seeds. The closure can be completed later during the upward movement of the installation tube 1.

[0078] It is worth noting that, see Figure 7 The design of the friction edge enables the side wheel 3 to drive the winding wheel 8 to rotate and reel when it rotates, but when the pull rope 18 drives the winding wheel 8 to rotate, the side wheel 3 will not affect the continued rotation of the winding wheel 8, so as to avoid interference in the travel.

[0079] In one of the more preferred embodiments, a friction plate 15 is further fixed to the side wall of the lifting rod 2, and the contact surface between the friction plate 15 and the side wheel 3 is set as a friction surface.

[0080] See also Figure 4 The design of the friction plate 15 can further improve the friction transmission effect between the friction plate 15 and the side wheel 3 to avoid slipping between the two and affecting the sowing process.

[0081] In one of the more preferred embodiments, the bottom opening edge of the arc shovel 11 is sharpened, and the inner wall of the arc shovel 11 is smooth. The sharpening can further facilitate the arc shovel 11 to shovel into the soil.

[0082] In one of the more preferred embodiments, the lifting rod 2 is driven by a telescopic cylinder installed on a traveling machine, and the traveling machine is equipped with two storage boxes for holding fertilizers and seeds respectively.

[0083] In one of the more preferred embodiments, a distance sensor for measuring the distance between the mounting tube 1 and the ground is also installed below the mounting tube 1. The distance sensor can more effectively control the distance between the mounting tube 1 and the ground, and thus can regulate the sowing and fertilization depth of each seed and fertilizer.

[0084] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0085] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
