Description

Technical Field

[0001] The present invention relates to the technical field of seed drills, in particular to a ridging seed drill. Background Art

[0002] The peanut ridging and seeder is a composite agricultural machine that integrates soil tillage, ridge forming, fertilization, sowing, and mulching. It is designed specifically for precision sowing of crops such as peanuts. Its core function is to optimize soil structure, drainage performance, and crop growth environment by constructing standardized ridges, while achieving single or double grain precision sowing, significantly improving sowing efficiency and seedling quality.

[0003] Current peanut ridging and seeding machines are typically towed by a tractor, which drives the ground wheels and distributes power to various functional modules through a transmission system. This rotary tillage and ridging process breaks up the soil and removes straw. Curved forming plates then gather the crushed soil toward the centerline to form a ridge. Furrows form at the lower levels on either side of the ridge. Fertilizer is then applied to these furrows, and furrows are opened on the ridge surface at the top of the ridge for seeding. Finally, soil is covered and compacted to complete the ridging and seeding process. Based on the characteristics of peanut seeds and sowing requirements (such as two-seed precision seeding), the seeding mechanism typically uses a pneumatic seed meter that accurately draws the target number of peanut seeds for sowing.

[0004] Existing technology usually directly forms ridges through ridge rolling during rotary tillage (or without rotary tillage), resulting in uneven distribution of soil resistance (especially in clay or straw-covered land), causing large deviations in ridge height and ridge top width, affecting subsequent sowing accuracy, and easily causing loose soil piles on both sides during the ridge forming process. During subsequent compaction, the soil is backfilled into the ridge ditch, and after the ditch is opened for sowing, the soil spreads to both sides, and direct compaction will cause the soil to flow laterally, resulting in uneven soil cover thickness. At the same time, the soil on the ridge top is pressed into the ridge ditch, thereby destroying the ridge shape. Summary of the Invention

[0005] The object of the present invention is to provide a ridging seeder to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A ridging and seeding machine comprises a machine body; further comprising: a front furrow plow, mounted on the front of the machine body, for loosening the soil and opening shallow furrows before ridging; a ridging mechanism, comprising a columnar portion and conical portions located at both ends of the columnar portion, for squeezing the soil on both sides toward the middle to form a ridge body, and compacting the shallow furrows on both sides of the ridge body to form ridge furrows, with anti-slip teeth fixedly connected to the outer periphery of the conical portion at equal intervals; a furrow opener, for opening a deep V-shaped seed furrow on the ridge surface at the top of the ridge body; a sowing mechanism, for sowing seeds in a fixed quantity; and a fertilizing mechanism, for applying fertilizer to the ridge body. Furrow; compensation mechanism, used to sow additional seeds when the sowing mechanism misses sowing; transmission mechanism, used to use the rotation of the ridging mechanism to generate power to drive the sowing mechanism and the fertilizing mechanism to work, including a sprocket and chain for connecting the central axis of the ridging mechanism and the sowing mechanism and the fertilizing mechanism; rear ridge plow, used to repair the ridge shape destroyed after furrowing, reshape the ridge shoulder after furrowing and sowing, and collect the overflowing soil through the curved profiling plate to restore the trapezoidal cross-section; suppression mechanism, installed at the rear of the machine body, used to compact the seed furrow and the surface soil of the ridge body.

[0008] By adopting the above technical solution, by setting up a front furrow plow, shallow furrows can be plowed in advance before ridge forming, and the position of the shallow furrow is exactly the path of travel of the conical parts at both ends of the ridging mechanism. The ridging mechanism can form ridges based on the soil pile between two adjacent shallow furrows. During the ridging process, the conical part of the soil extends into the shallow furrow and applies force to the central part, thereby avoiding the soil at the edge (the original shallow furrow position) being excessively compacted by the conical part; and a rear ridge plow is set to "repair" the ridge body after furrowing and sowing, pushing the soil scattered during the sowing process back to the top of the ridge, avoiding the damage to the ridge structure caused by the backfilling of soil into the ridge furrow after sowing and compaction by the suppression mechanism, which is beneficial to the maintenance of the ridge structure.

[0009] A further improvement of the technical solution of the present invention is that the sowing mechanism includes a seed box and a seeding shell, the mouth of the seeding shell is fixedly connected to a protective shell, one side of the inner wall of the protective shell is rotatably connected to a drive shaft, one end of the drive shaft is fixedly connected to a seeding plate, and a driving structure for controlling the rotation of the drive shaft and the seeding plate is provided inside the protective shell; the seeding plate is in contact with the mouth of the seeding shell, and a plurality of suction holes arranged in a ring are provided on the seeding plate, and a ring-shaped partition plate is fixedly connected to the side of the seeding plate close to the protective shell, and the interior of the partition plate is equidistantly divided into cavities equal in number to the suction holes, The inner wall of the disk is provided with connecting holes equal to the number of the chambers; the inner wall of the separating disk is rotatably connected to the distribution disk, the distribution disk is fan-shaped, and the side wall is provided with an air groove, a sealing ring is provided between the distribution disk and the separating disk, an air pump is fixedly installed on the machine body, and the air pump and the distribution disk are connected through a pipeline; a feed pipe connected to the seed box is provided on one side of the seeding shell, and a discharge pipe is provided at the bottom, the bottom end of the discharge pipe extends to the inside of the furrow opener, and a partition plate is fixedly connected to the inside of the seeding shell, and the discharge pipe and the feed pipe are respectively located on both sides of the partition plate; the aperture of the suction hole is larger than the connecting hole.

[0010] The above technical solution is adopted, by dividing the separation plate shared by each suction hole into several independent chambers, and each independent chamber is connected to the distribution plate. By evacuating the distribution plate, and then using the connecting hole facing the air groove to transmit negative pressure, the negative pressure can be transmitted to the chamber facing the air groove. In the above process, the distribution plate acts as a pressure-stabilizing tank, and the external air pump only needs to continuously maintain the pressure value of the above distribution plate. Since the distribution plate and the chambers of the separation plate are also connected through the connecting hole, and there is an additional transfer chamber, and at the same time, it is limited by the aperture of the connecting hole, so that the mutual disturbance effect between the suction holes is reduced, thereby reducing the influence of air pressure changes on the adsorption of seeds.

[0011] A further improvement of the technical solution of the present invention is that the driving structure includes an outer groove wheel fixedly connected to the outside of the driving shaft, the inner side of the protective shell is rotatably connected to the driving wheel, one side of the driving wheel is fixedly connected to a first shift rod, the first shift rod is used in conjunction with the notch on the outside of the outer groove wheel, the central axis of the driving wheel extends to the outside of the protective shell, and is connected to the ridge-forming mechanism through a transmission mechanism.

[0012] The above technical solution is adopted, and a groove wheel mechanism is set up to change the seed delivery mode of the seed plate from continuous to intermittent (that is, it stops after rotating a certain arc, and stops after rotating again, and the overall rotation period remains unchanged), so that there is enough time for the suction operation in the stop gap of the rotation of the seed plate, thereby increasing the probability of seeds being adsorbed and reducing the occurrence of missed seeds; specifically, in the process of the ridging mechanism rotating with the movement of the machine body, the drive wheel is driven to rotate through the transmission mechanism, and the first shifting rod is driven to rotate around the central axis of the drive wheel, and the outer groove wheel is periodically shifted, so that for every rotation of the drive wheel, the corresponding outer groove wheel rotates a certain arc, so that the drive shaft rotates intermittently during the rotation of the ridging mechanism, thereby driving the seed plate to rotate intermittently.

[0013] A further improvement of the technical solution of the present invention is that: the distribution disc is rotatably connected to the inner groove wheel on the side away from the seed plate, the central axis of the inner groove wheel is a hollow shaft, and the driving wheel is fixedly connected to the second lever on the side away from the first lever, and the second lever is used in conjunction with the notch inside the inner groove wheel; the driving shaft is a hollow rod, and the inside of the protective shell is located inside the driving shaft and is rotatably connected to a core rod, one end of the core rod extends to the inside of the seed discharging shell through the driving shaft and is fixedly connected to the material discharging blade; the inner side of the protective shell is rotatably connected to a driven gear, and the outer wall of the inner groove wheel is fixedly connected to a driving ring gear, which is meshed with the driven gear, and the central axis of the driven gear and one end of the core rod both extend to the outside of the protective shell, and are connected by a synchronous wheel and a synchronous belt transmission.

[0014] By adopting the above technical solution, by setting the material-placing blade, the stacked seed grains can be moved to reduce the weight of the seed grains piled in the middle, so that the seeds located below can move during the movement of the machine body, thereby increasing the probability that the middle of the seed is facing the material suction hole; specifically, during the rotation of the driving wheel, it will also drive the second shifting rod to make a circular motion around the center of the driving wheel, and periodically shift the inner groove wheel, so that the inner groove wheel rotates intermittently, and drives the core rod to rotate through the synchronous wheel and the synchronous belt transmission, further driving the material-placing blade to rotate, thereby moving the seeds located in the middle to one side. The side shifting reduces the amount of seeds accumulated in the middle, so that the seeds located in the middle near the bottom can move along with the movement of the machine body; it should be noted that the inner groove wheel and the outer groove wheel share a driving wheel for movement, and the movement states of the two are opposite, that is, when the inner groove wheel rotates, the outer groove wheel is stationary, and when the outer groove wheel rotates, the inner groove wheel is stationary. Therefore, when the seed plate rotates, no material is shifted, the seeds are relatively stable and the suction holes move to cater to the position of the seeds. On the contrary, when the seed plate (suction hole) is stationary, the shifting blades move, thereby avoiding interference between the two activities when the adsorption is not stable, thereby affecting the adsorption.

[0015] A further improvement of the technical solution of the present invention is that: the separating disk is fixedly connected to a feedback tube at the position of each chamber, the feedback tube corresponds to each chamber one by one and is connected, a spacer is fixedly connected to the middle position of the inner wall of the feedback tube, a first slide rod is slidably connected through the spacer, one end of the first slide rod is fixedly connected to a piston plate, the piston plate and the inner wall of the feedback tube are in contact with each other, the end of the first slide rod away from the piston plate is fixedly connected to a limiting plate, and the outside of the first slide rod is provided with a first spring between the limiting plate and the spacer.

[0016] By adopting the above technical solution, a feedback cylinder is set. When the seeds are sucked by the suction hole, the corresponding chamber on the separation plate is blocked, so that the negative pressure increases until it approaches the pressure in the distribution plate. During the process, due to the action of the negative pressure, the piston plate moves to the side close to the chamber, driving the first slide bar and the limit part to move and squeeze the first spring to accumulate potential energy. When it reaches the seeding area, since the connecting hole is connected to the external environment, the pressure in the chamber will be quickly released through the connecting hole. At this time, based on the pressure reduction in the chamber, the first spring rebounds and pushes the limit plate, the first slide bar and the piston plate to reset, so that the chamber obtains pressure compensation, that is, the negative pressure in the chamber will not be released immediately, so that the seeds will not be released immediately when they rotate to the seeding area, but will stay temporarily for a period of time until the seeding plate is in a stationary state and the pressure inside the feedback cylinder is completely released. At this time, the pressure in the chamber is not enough to absorb the seeds, so that the seeds are released without initial velocity and in free fall motion, thereby reducing the problem of seeds being easily damaged when released with initial velocity.

[0017] The further improvement of the technical solution of the present invention is that: the compensation mechanism includes a feeding rack, a pushing block is slidably connected between the inner walls of the feeding rack, a through slot for taking materials is provided in the middle of the pushing block, and the top of the feeding rack is fixedly connected with an input pipe, the input pipe is funnel-shaped, and the top is communicated with the bottom of the seeding shell; an output pipe is provided at the bottom of the feeding rack, and the output pipe is communicated with the discharge pipe; a second spring is fixedly connected between one end of the pushing block and one side of the inner wall of the feeding rack, a strip groove is provided on one side of the feeding rack, and the side wall of the pushing block is fixedly connected with a push rod, and the push rod extends to the outside of the feeding rack through the strip groove; a linkage rack is hinged on one side of the inner wall of the protective shell, and a give way slot for the linkage rack to pass is provided on the protective shell, one end of the linkage rack contacts the push rod, and the side of the limit plate away from the first sliding rod is fixedly connected with a top block used in conjunction with the linkage rack; the edge of the through slot mouth is rounded.

[0018] With the above technical solution, when the suction hole leaks, the piston plate, first slide rod, and limit plate in the corresponding feedback cylinder are all inactive, so that when the top block rotates to the discharge area, it contacts the linkage frame. As the seed plate moves, it presses the linkage frame, causing the linkage frame to rotate. At the same time, the other end of the linkage frame squeezes the push rod and drives the push block to move. Before the push block moves, the through groove on the push block faces the bottom end of the input tube, allowing seeds to fall from the seed discharging housing through the input tube into the through groove; when the push block is pushed, the through groove carries the seeds to move to face the output tube, causing the seeds to fall into the output tube and then fall along the output tube into the discharge tube, thus completing the compensation discharge. During the above process, the second spring is compressed and accumulates potential energy.

[0019] A further improvement of the technical solution of the present invention is that: a mounting groove is provided on the top of the feeding rack and communicates with the inner wall of the feeding rack, a wedge is slidably connected between the inner walls of the mounting groove, a second slide rod is fixedly connected to one side of the wedge, a fixed plate is fixedly connected to the inside of the mounting groove, the second slide rod passes through the fixed plate and is fixedly connected to a pad, the second slide rod is slidably connected to the pad, the pad contacts the end of the pushing block, and a third spring is sleeved on the outside of the second slide rod and located between the wedge and the fixed plate.

[0020] The above technical solution is adopted, by arranging a wedge block inside the feeding rack to temporarily block the seeds, so as to reduce the damage of the pushing block to the seeds; when the pushing block is not pushed, the third spring is in a compressed state; when the pushing block is pushed (for compensatory seeding), the pad loses the support of the pushing block, so under the rebound action of the third spring, the wedge is pushed out to between the seeds to be discharged and the seeds at the bottom of the input tube, and drives the second slide bar and the pad to move. After the wedge is extended, the inclined surface contacts the seeds, and cooperates with the arc surface of the bottom end of the seed to lift the seeds upward and break away from the contact with the pushing block, thereby avoiding the problem of seed damage; and when the pushing block is reset, the pad is pushed to reset at the same time, and the wedge is driven to reset by the second slide bar, the third spring is compressed again, and the seeds can pass through the input tube into the through groove.

[0021] A further improvement of the technical solution of the present invention is that a brush is fixedly connected to one side of the inner wall of the seeding shell, and the bristles of the brush are in contact with the seeding plate.

[0022] With the above technical solution, a brush is provided in the seeding housing, and its bristles are in contact with the suction holes of the seeding plate. During the rotation of the seeding plate, the brush moves relative to the brush, thereby brushing off the seed coat or debris, reducing the problem of subsequent unstable adsorption caused by debris.

[0023] A further improvement of the technical solution of the present invention is that the pressing mechanism includes a pressing roller, the outer side wall of the pressing roller is fixedly connected to a plurality of anti-sticking cloths, and the anti-sticking cloths are fixedly connected to the outside of the pressing roller in an annular shape and at equal intervals.

[0024] By adopting the above technical solution, in wet soil operation scenarios, the fabric structure can reduce the adhesion between soil and metal. The "folding structure" formed by the anti-stick cloth can shake off the soil during rotation, automatically peeling off the residue on the surface of the roller and maintaining efficient operation of the equipment.

[0025] Due to the adoption of the above technical solution, the present invention has the following technical advancements compared to the prior art:

[0026] 1. The present invention provides a ridging seeder. By arranging a front furrow plow, shallow furrows can be plowed in advance before ridging. The positions of the shallow furrows are exactly the paths for the conical parts at both ends of the ridging mechanism to travel. The ridging mechanism can perform ridging based on the soil pile between two adjacent shallow furrows. During the ridging process, the conical part of the soil extends into the shallow furrow and applies force to the central part, thereby preventing the soil at the edge (the original shallow furrow position) from being excessively compacted by the conical part. A rear ridge plow is arranged to "repair" the ridge body after furrowing and sowing, pushing the soil scattered during the sowing process back to the top of the ridge, thereby preventing the ridge body structure from being damaged due to the soil backfilling into the ridge furrow after sowing and being compacted by the suppression mechanism, which is beneficial to the maintenance of the ridge body structure.

[0027] 2. The present invention provides a ridge-forming seeder, which divides a partition plate shared by each suction hole into several independent chambers, and each independent chamber is connected to a distribution plate. The distribution plate is vacuumed, and negative pressure is transmitted through the connecting hole facing the air groove, so that the negative pressure can be transmitted to the chamber facing the air groove. In the above process, the distribution plate acts as a pressure-stabilizing tank, and the external air pump only needs to continuously maintain the pressure value of the distribution plate. Since the distribution plate and the chambers of the partition plate are connected through the connecting hole, and there is an additional transfer chamber, and the aperture of the connecting hole is limited, the mutual disturbance between the suction holes is reduced, thereby reducing the influence of air pressure changes on the adsorption of seed particles.

[0028] 3. The present invention provides a ridging seeder, which is equipped with a grooved wheel mechanism to change the seed feeding mode of the seeding plate from a continuous mode to an intermittent mode, so that there is enough time for the suction operation in the stop interval of the rotation of the seeding plate, thereby increasing the probability of seeds being adsorbed and reducing the occurrence of missed seeds; specifically, in the process of the ridging mechanism rotating as the machine body moves, the driving wheel is driven to rotate through the transmission mechanism, and the first shifting rod is driven to rotate around the central axis of the driving wheel, and the outer grooved wheel is periodically shifted, so that for every rotation of the driving wheel, the corresponding outer grooved wheel rotates a certain arc, so that the drive shaft rotates intermittently during the rotation of the ridging mechanism, thereby driving the seeding plate to feed intermittently, leaving enough time to adsorb seeds.

[0029] 4. The present invention provides a ridge seeder, which is provided with a feedback cylinder. When the seeds are sucked by the suction hole, the corresponding chamber on the separation plate is blocked, so that the negative pressure increases until it approaches the pressure in the distribution plate. During the process, due to the action of the negative pressure, the piston plate moves to the side close to the chamber, and drives the first slide bar and the limit part to move and squeeze the first spring to accumulate potential energy. When the seeding area is reached, the pressure in the chamber is quickly released through the connecting hole. At this time, based on the pressure reduction in the chamber, the first spring rebounds and pushes the piston plate to reset, so that the chamber obtains pressure compensation, that is, the negative pressure in the chamber will not be released immediately, so that the seeds will not be released immediately when they rotate to the seeding area, but will stay temporarily for a period of time until the seeding plate is in a stationary state and the pressure inside the feedback cylinder is completely released. At this time, the pressure in the chamber is not enough to absorb the seeds, so that the seeds are released without initial velocity and move in free fall, thereby reducing the problem that the seeds are easily damaged when released with initial velocity.

[0030] 5. The present invention provides a ridging seeder. By setting a compensation mechanism, when the suction hole leaks, the piston plate, first slide rod and limit plate in the corresponding feedback cylinder are all inactive, so that when the top block rotates to the discharge area, it will contact the linkage frame. As the seed plate moves, the linkage frame is pressed, causing the linkage frame to rotate. At the same time, the other end of the linkage frame squeezes the push rod and drives the push block to move. Before the push block moves, the through groove on the push block faces the bottom end of the input pipe, allowing the seeds to fall from the seed discharge housing through the input pipe into the through groove; when the push block is pushed, the through groove carries the seeds and moves to face the output pipe, causing the seeds to fall into the output pipe and then fall into the discharge pipe along the output pipe, completing the compensation discharge.

DETAILED DESCRIPTION

[0048] The present invention is further described in detail below with reference to the embodiments.

[0049] Example 1

[0050] like Figures 1-15 As shown, the present invention provides a ridging and seeding machine, comprising a machine body 1; further comprising: a front furrow plow 11, mounted on the front of the machine body 1, for pre-loosening the soil and opening shallow furrows before ridging; a ridging mechanism 2, comprising a columnar portion 21 and conical portions 22 located at both ends of the columnar portion 21, for squeezing the soil on both sides toward the middle to form a ridge body, and compacting the shallow furrows on both sides of the ridge body to form ridge furrows, with anti-slip teeth 23 fixedly connected to the outer periphery of the conical portion 22 at equal intervals; a furrow opener, for opening a deep V-shaped seed furrow on the ridge surface at the top of the ridge body; a sowing mechanism 3, for quantitatively sowing seeds; and a fertilizing mechanism. , used to apply fertilizer into the ridge furrow; the compensation mechanism is used to sow seeds when the sowing mechanism 3 misses sowing; the transmission mechanism is used to use the rotation of the ridging mechanism 2 to generate power to drive the sowing mechanism 3 and the fertilizing mechanism to work, including a sprocket and chain for connecting the central axis of the ridging mechanism 2 and the sowing mechanism 3 and the fertilizing mechanism; the rear ridge plow 12 is used to repair the ridge shape destroyed after furrowing, reshape the ridge shoulder after furrowing and sowing, and collect the overflowing soil through the curved profiling plate to restore the trapezoidal cross-section; the suppression mechanism is installed at the rear of the machine body 1, and is used to compact the seed furrow and the surface soil of the ridge body.

[0051] By setting up the front furrow plow 11, shallow furrows can be plowed in advance before ridge forming, and the position of the shallow furrow is exactly the path of the conical parts 22 at both ends of the ridge forming mechanism 2. The ridge forming mechanism 2 can form ridges based on the soil pile between two adjacent shallow furrows. During the ridge forming process, the soil conical part 22 extends into the shallow furrow and applies force to the central part, thereby avoiding the soil at the edge (the original shallow furrow position) being excessively compacted by the conical part 22; and the rear ridge plow 12 is set to "repair" the ridge body after furrowing and sowing, and push the soil scattered during the sowing process back to the top of the ridge, thereby avoiding the damage to the ridge structure caused by the backfilling of soil into the ridge furrow after sowing and compaction by the suppression mechanism, which is beneficial to the maintenance of the ridge structure.

[0052] Specifically, the front furrow plow 11 is in front of the machine body 1. When the machine body 1 moves, the front furrow plow 11 first cuts into the soil, and the plow tip is designed in a V shape, opening two symmetrical guide furrows, loosening the surface compacted soil at the same time, and dispersing the subsequent ridge-forming resistance; the columnar part 21 of the ridge-forming mechanism 2 presses the soil in the center, and the conical parts 22 at both ends squeeze the soil on both sides toward the center line to form a trapezoidal ridge body, among which the anti-skid teeth 23 on the outer periphery of the conical part 22 of the ridge-forming mechanism 2 are embedded in the soil during rotation to prevent slipping, and simultaneously compact the guide furrow to form a standard ridge furrow; the furrow opener is in the center of the ridge top A V-shaped seed furrow with a depth of 3 to 5 cm and a width of 5 to 8 cm is opened, and at the same time, the fertilizer mechanism applies fertilizer quantitatively to the bottom of the furrow through a spiral fertilizer dispenser; the seeding device in the sowing mechanism 3 is set as an air-suction seeding device, which can accurately absorb the seeds and put them into the seed furrow; after the above-mentioned furrowing and sowing, the soil on the top of the ridge is scattered to both sides, and a rear ridge plow 12 with a curved profile plate is set. The rear curved plow plate will gather the soil turned over during furrowing back to the ridge shoulder to restore the trapezoidal cross-section; finally, the ridge body is compacted by the suppression mechanism to complete the sowing.

[0053] Structurally, two seeding channels, namely the sowing mechanism 3 and the compensation mechanism, are used to compensate for sowing when the sowing mechanism 3 misses sowing. The above redundant design ensures the accuracy of sowing and improves the effect of the operation.

[0054] Example 2

[0055] like Figure 3 、 Figure 4 and Figure 5As shown, based on Example 1, the present invention provides a technical solution: preferably, the sowing mechanism 3 includes a seed box 31 and a seeding shell 32, the mouth of the seeding shell 32 is fixedly connected to a protective shell 33, one side of the inner wall of the protective shell 33 is rotatably connected to a drive shaft 310, one end of the drive shaft 310 is fixedly connected to a seeding plate 34, and the interior of the protective shell 33 is provided with a driving structure 4 for controlling the rotation of the drive shaft 310 and the seeding plate 34; the seeding plate 34 is in contact with the mouth of the seeding shell 32, and a plurality of suction holes 35 arranged in an annular manner are opened on the seeding plate 34, and the seeding plate 34 is fixedly connected to a ring-shaped partition plate 36 near the side of the protective shell 33, and the interior of the partition plate 36 is equidistantly divided into chambers 311 equal in number to the suction holes. The inner wall of the separating plate 36 is provided with connecting holes 38, the number of which is equal to and connected to the chamber 311; the inner wall of the separating plate 36 is rotatably connected to the distribution plate 37, the distribution plate 37 is fan-shaped, and an air groove 39 is provided on the side wall, and a sealing ring is provided between the distribution plate 37 and the separating plate 36, and an air pump is fixedly installed on the body 1, and the air pump is connected to the distribution plate 37 through a pipeline; a feed pipe 314 connected to the seed box 31 is provided on one side of the seeding shell 32, and a discharge pipe 313 is provided at the bottom, and the bottom end of the discharge pipe 313 extends to the interior of the furrow opener, and the interior of the seeding shell 32 is fixedly connected to the separating plate 312, and the discharge pipe 313 and the feed pipe 314 are respectively located on both sides of the separating plate 312; the aperture of the suction hole 35 is larger than the connecting hole 38.

[0056] Existing pneumatic (air suction) seeding devices usually adopt a method of directly connecting the suction hole 35 to a negative pressure chamber for suction. The seeding plate 34 rotates and generates negative pressure at the suction hole 35. When the seed moves near the suction hole 35, it is adsorbed to achieve suction. However, the adsorption of seed particles by the suction holes 35 is in a constantly changing dynamic process, which also causes the internal pressure of the negative pressure chamber shared by each suction hole 35 to constantly change. As a result, some unstable seed particles caused by adsorption posture and seed particles with irregular structures may be adsorbed at the beginning, but will fall off after the above-mentioned adsorption pressure changes, resulting in missed seeding.

[0057] If you refer to the attached Figure 14The seed distribution structure diagram shown in FIG. 1 is a diagram of a seed discharging process, wherein the seed discharging process is divided into four areas, area I is a seed suction area, which is used to absorb seeds when the suction hole 35 passes through the seed retention area; area II is a seed delivery area, which is used to deliver seeds; area III is a seed discharging area, which is used to remove the negative pressure of the suction hole 35 to release the seeds; area IV is a seed cleaning area, which can remove seeds or seed coat residues that have not been completely discharged from the seed discharging area; since it is a probabilistic event for the suction hole 35 to adsorb seeds in the seed absorption area of ​​area I, although the probability of adsorbing seeds can be increased by stirring the seeds, the adsorption time is still uncertain, and the various suction holes 35 share a chamber 311, so that the internal pressure of each suction hole 35 changes continuously, so that the seeds that are not stably adsorbed in the seed delivery area of ​​area II may fall off, thereby causing missed sowing;

[0058] By dividing the partition plate 36 shared by each suction hole 35 into several independent chambers 311, and each independent chamber 311 is connected to the distribution plate 37, the distribution plate 37 is evacuated, and the negative pressure is transmitted through the connecting hole 38 facing the air groove 39, so that the negative pressure can be transmitted to the chamber 311 facing the air groove 39. In the above process, the distribution plate 37 acts as a pressure-stabilizing tank, and the external air pump only needs to continuously maintain the pressure value of the above-mentioned distribution plate 37. Since the distribution plate 37 and the chambers 311 of the partition plate 36 are connected through the connecting hole 38, and since there is an additional transfer chamber 311, and at the same time, it is limited by the aperture of the connecting hole 38, the mutual disturbance effect between the various suction holes 35 is reduced, thereby reducing the influence of air pressure changes on the adsorption of seeds.

[0059] Specifically, the driving structure 4 is used to control the rotation of the seed plate 34, and the seeds adsorbed on the suction holes 35 are carried until they are discharged. When the suction holes are in the seed suction area of ​​area I and the seed delivery area of ​​area II, the connecting holes 38 are facing the air grooves 39. The negative pressure in the distribution plate 37 can be transmitted to the corresponding chamber 311 of the separation plate 36 through the air grooves 39 and the connecting holes 38, and then the air is continuously pumped through the suction holes 35 until the seeds are adsorbed. The seeds pass through the seed delivery area and reach the seed discharging area, and the connecting holes 38 in this area are facing the fan-shaped notch of the distribution plate 37, that is, they are connected to the external environment, so that the negative pressure in the chamber 311 of this area in the separation plate 36 will be released outward through the connecting holes 38. After the negative pressure is lost, the seeds are no longer adsorbed, so that the seeds are released. After being released, the seeds are discharged from the discharge pipe 313, and the discharge position is the furrowing position of the furrow opener; wherein, a filter is provided inside the suction hole 35 to prevent the separation plate 36 from sucking in impurities or seed coats that fall off the seeds.

[0060] Among them, the aperture of the suction hole 35 is larger than the connecting hole 38, so that the pressure change in the chamber 311 of the separation plate 36 is always faster than that of the distribution plate 37, producing a certain hysteresis effect, reducing the influence of the different pressures in the separation plate 36 (when the suction hole 35 absorbs seeds and when it does not absorb seeds) on the internal pressure of the distribution plate 37 (it takes time for the pressure to be transmitted through the connecting hole 38).

[0061] There are two parallel seeding shells 32 in the seeding mechanism, corresponding to the two seeding channels that move synchronously, that is, two seeds are discharged to the same position each time the seeding is performed.

[0062] like Figure 6 、 Figure 7 and Figure 10 As shown, preferably, the driving structure 4 includes an outer groove wheel 43 fixedly connected to the outside of the driving shaft 310, and the inner side of the protective shell 33 is rotatably connected to the driving wheel 41. The central axis of the driving wheel 41 is connected to the central axis of the ridging mechanism 2 through a sprocket and a chain (i.e., a transmission mechanism). A first shift rod 42 is fixedly connected to one side of the driving wheel 41, and the first shift rod 42 is used in conjunction with the notch on the outside of the outer groove wheel 43. The central axis of the driving wheel 41 extends to the outside of the protective shell 33, and is connected to the ridging mechanism 2 through a transmission mechanism.

[0063] In the scheme, the rotation of the seed plate 34 relies on the rotation of the ground wheel (the ridging mechanism 2 in the scheme) to provide power through the transmission mechanism. Therefore, the rotation of the seed plate 34 is continuous and synchronized with the movement of the machine body 1. Although it can cooperate with the movement of the machine body 1 to synchronize seeding, the continuous rotation of the seed plate 34 will also affect the probability of seed absorption. The seeds will turn away from the position of the seeds in the suction hole 35 before the adsorption is completed (when the seeds are at the position of the suction hole 35, the negative pressure in the chamber 311 corresponding to the suction hole 35 continues to increase, and the seeds will be absorbed after a period of time. However, if the seed plate 34 continues to rotate, the negative pressure may increase to a level sufficient to absorb the seeds and the seed plate will turn away from the position. In particular, the seeds are piled in the seeding shell 32, so a certain adsorption force is required). Therefore, it is more likely to miss sowing.

[0064] By setting a groove wheel mechanism, the seed delivery mode of the seed plate 34 is changed from continuous to intermittent (that is, it stops after rotating for a certain arc, and stops after rotating again, and the overall rotation period remains unchanged), so that there is enough time for the suction operation in the stop gap of the rotation of the seed plate 34, thereby increasing the probability of seeds being adsorbed and reducing the occurrence of missed seeds; specifically, in the process of the ridging mechanism 2 rotating along with the movement of the machine body 1, the drive wheel 41 is driven to rotate through the transmission mechanism, and the first shifting rod 42 is driven to rotate around the central axis of the drive wheel 41, and the outer groove wheel 43 is periodically shifted, so that for every rotation of the drive wheel 41, the corresponding outer groove wheel 43 rotates for a certain arc, so that the drive shaft 310 rotates intermittently during the rotation of the ridging mechanism 2, thereby driving the seed plate 34 to rotate intermittently.

[0065] Example 3

[0066] like Figure 6 、 Figure 7 and Figure 10 As shown, on the basis of Example 2, the present invention provides a technical solution: preferably, the distribution disc 37 is rotatably connected to the side of the seeding plate 34 with an inner groove wheel 57, the center axis of the inner groove wheel 57 is a hollow shaft, and the driving wheel 41 is fixedly connected to the side of the first lever 42 with a second lever 53, and the second lever 53 is used in conjunction with the notch inside the inner groove wheel 57; the driving shaft 310 is a hollow rod, and the protective shell 33 is located inside the driving shaft 310 and is rotatably connected to the core rod 51, one end of the core rod 51 extends to the interior of the seeding outer shell 32 through the driving shaft 310 and is fixedly connected to the material-discharging blade 52; the inner side of the protective shell 33 is rotatably connected to the driven gear 56, and the outer wall of the inner groove wheel 57 is fixedly connected to the driving ring gear 55, which is meshed with the driven gear 56, and the center axis of the driven gear 56 and one end of the core rod 51 both extend to the outside of the protective shell 33, and are connected by a synchronous wheel and a synchronous belt transmission.

[0067] Since the seed plate 34 rotates intermittently, the seeds stored in the seed housing 32 are piled together and have poor fluidity. In particular, the seeds at the bottom are squeezed by the gravity of the seeds above, making it difficult to move. The adsorbed seeds also need to overcome greater resistance to be carried. When the seeds at the bottom are arranged in a posture that is not easy to be adsorbed, the adsorption probability will be affected, resulting in missed sowing (there are gaps between the seeds themselves, and the gaps cannot be adsorbed. Stable adsorption can only be achieved when the middle of any side of the seed is facing the suction hole 35);

[0068] By providing the material-dispensing blade 52, the stacked seeds can be moved to reduce the weight of the seeds stacked in the middle, so that the seeds located at the bottom can move during the movement of the machine body 1, thereby increasing the probability that the middle of the seeds are facing the suction hole 35; specifically, during the rotation of the driving wheel 41, it will also drive the second shifting rod 53 to make a circular motion around the center of the driving wheel 41, and periodically shift the inner groove wheel 57, so that the inner groove wheel 57 rotates intermittently, and drives the core rod 51 to rotate through the synchronous wheel and the synchronous belt transmission, further driving the material-dispensing blade 52 to rotate, thereby shifting the seeds located in the middle to one side, reducing the weight of the seeds in the middle. The amount of seeds accumulated in the upper part is increased, so that the seeds located in the middle near the bottom can move along with the movement of the machine body 1; it should be noted that the inner groove wheel 57 and the outer groove wheel 43 share the driving wheel 41 for driving, and the action states of the two are opposite, that is, when the inner groove wheel 57 rotates, the outer groove wheel 43 is stationary, and when the outer groove wheel 43 rotates, the inner groove wheel 57 is stationary. Therefore, when the seed plate 34 rotates, no material is transferred, the seeds are relatively stable and the suction holes 35 move to cater to the seed position. On the contrary, when the seed plate 34 (suction holes 35) are stationary, the transfer blade 52 moves, thereby avoiding interference between the two activities when the adsorption is not stable, thereby affecting the adsorption.

[0069] Example 4

[0070] like Figure 7 、 Figure 9 and Figure 11 As shown, on the basis of Example 3, the present invention provides a technical solution: preferably, the separation disk 36 is located at the position of each chamber 311 and is fixedly connected to a feedback tube 81, the feedback tube 81 corresponds to each chamber 311 one by one and is connected, and the middle position of the inner wall of the feedback tube 81 is fixedly connected to a spacer 82, and a first slide rod 83 is slidably connected through the spacer 82, one end of the first slide rod 83 is fixedly connected to a piston plate 84, the piston plate 84 is in contact with the inner wall of the feedback tube 81, and the end of the first slide rod 83 away from the piston plate 84 is fixedly connected to a limiting plate 85, and the outside of the first slide rod 83 is located between the limiting plate 85 and the spacer 82 and is sleeved with a first spring 86.

[0071] The existing seed metering device releases negative pressure when the seeds reach the seeding area, thereby releasing the seeds. However, the seeding plate 34 continues to rotate, so that the seeds must carry a certain centrifugal force when released, causing the seeds to be thrown out in the form of an outward movement trend. In particular, in this solution, the seeding disc rotates intermittently and the total rotation cycle remains unchanged. Therefore, in order to compensate for its static time, it has a faster speed when rotating, so that the seeds are thrown out at a greater speed, causing the seeds to be easily damaged by collision.

[0072] By setting the feedback cylinder 81, when the suction hole 35 sucks the seeds, the corresponding chamber 311 on the separation plate 36 is blocked, so that the negative pressure increases until it approaches the pressure in the distribution plate 37. During the process, due to the negative pressure, the piston plate 84 moves to the side close to the chamber 311, and drives the first slide bar 83 and the limit part to move and squeeze the first spring 86 to accumulate potential energy. When it reaches the seeding area, since the connecting hole 38 is connected to the external environment, the pressure in the chamber 311 is quickly released through the connecting hole 38. At this time, based on the pressure reduction in the chamber 311, the first spring The spring 86 rebounds and pushes the limit plate 85, the first slide rod 83 and the piston plate 84 to reset, so that the chamber 311 obtains pressure compensation, that is, the negative pressure in the chamber 311 will not be released immediately, so that the seeds will not be released immediately when they rotate to the seeding area, but will stay temporarily for a period of time until the seeding plate 34 is in a stationary state and the pressure inside the feedback cylinder 81 is completely released. At this time, the pressure in the chamber 311 is not enough to absorb the seeds, so that the seeds are released without initial velocity and move in free fall, thereby reducing the problem of seeds being easily damaged when released with initial velocity.

[0073] It should be noted that when the suction hole 35 does not adsorb seeds, since the chamber 311 is directly connected to the outside (seed discharging shell 32) through the suction hole 35, the negative pressure is directly released from the suction hole 35, and the adsorption effect in the distribution plate 37 is transmitted to the chamber 311 at a slower speed, so that the pressure in the chamber 311 is at a low level, and this state is not sufficient to make the piston plate 84 move.

[0074] Example 5

[0075] like Figure 8 and Figure 12 As shown, on the basis of Example 4, the present invention provides a technical solution: preferably, the compensation mechanism includes a feeding rack 61, a pushing block 64 is slidably connected between the inner walls of the feeding rack 61, a through slot 65 for taking materials is provided in the middle of the pushing block 64, an input pipe 63 is fixedly connected to the top of the feeding rack 61, the input pipe 63 is funnel-shaped, and the top is communicated with the bottom of the seeding shell 32; an output pipe 62 is provided at the bottom of the feeding rack 61, and the output pipe 62 is communicated with the discharge pipe 313; between one end of the pushing block 64 and one side of the inner wall of the feeding rack 61 A second spring 66 is fixedly connected, a strip groove 610 is provided on one side of the feeding rack 61, and a push rod 69 is fixedly connected to the side wall of the pushing block 64, which extends to the outside of the feeding rack 61 through the strip groove 610; a linkage frame 67 is hinged on one side of the inner wall of the protective shell 33, and a makeshift groove for the linkage frame 67 to pass through is provided on the protective shell 33, one end of the linkage frame 67 is in contact with the push rod 69, and the side of the limit plate 85 away from the first slide rod 83 is fixedly connected to a top block 68 used in conjunction with the linkage frame 67; the edge of the mouth of the through groove 65 is rounded.

[0076] Although the above solution can reduce the leakage of the suction hole 35, the leakage problem is still a probabilistic event, so there is still a possibility of missed broadcasting;

[0077] When the suction hole 35 leaks suction, the piston plate 84, the first slide rod 83 and the limit plate 85 in the corresponding feedback cylinder 81 are all inactive, so that when the top block 68 rotates to the discharge area, it will contact the linkage frame 67. As the seed plate 34 moves, the linkage frame 67 is pressed, causing the linkage frame 67 to rotate. At the same time, the other end of the linkage frame 67 squeezes the push rod 69 and drives the push block 64 to move. Before the push block 64 moves, the through groove 65 on the push block 64 is opposite to the bottom end of the input pipe 63, so that the seeds can fall from the seed discharging housing 32 through the input pipe 63 into the through groove 65; when the push block 64 is pushed, the through groove 65 carries the seeds and moves to face the output pipe 62, so that the seeds fall into the output pipe 62 and fall into the discharge pipe 313 along the output pipe 62, thus completing the compensation discharge. In the above process, the second spring 66 is compressed and accumulates potential energy.

[0078] After the linkage frame 67 swings to a certain angle (the angle required for the above-mentioned compensation for discharging), the top block 68 disengages and moves to the end of the linkage frame 67. The movement of the top block 68 no longer pushes the linkage frame 67 to rotate, so that the linkage frame 67 no longer hinders the movement of the top block 68. At the same time, the top block 68 does not hinder the reset of the linkage frame 67, and then pushes the push block 64 to reset under the rebound of the second spring 66 until the through groove 65 is directly under the input pipe 63, and at the same time drives the push rod 69 to move and push the linkage frame 67 to rotate and reset to the initial position (in the initial position, the linkage rod is limited by the yield groove on the protective shell 33).

[0079] like Figure 8 、 Figure 12 and Figure 15 As shown, preferably, a mounting groove 71 communicating with the inner wall of the mounting groove 61 is opened at the top of the feeding rack 61, a wedge block 74 is slidably connected between the inner walls of the mounting groove 71, a second slide bar 73 is fixedly connected to one side of the wedge block 74, a fixed plate 72 is fixedly connected to the inside of the mounting groove 71, the second slide bar 73 passes through the fixed plate 72 and is fixedly connected to a pad 76, the second slide bar 73 is slidably connected to the pad 76, the pad 76 contacts the end of the pushing block 64, and a third spring 75 is sleeved on the outside of the second slide bar 73 and located between the wedge block 74 and the fixed plate 72.

[0080] Considering that during the compensation seeding process, the pusher block 64 moves, and there are a number of seeds arranged vertically above the pusher block 64, the movement of the pusher block 64 will cause wear and even crush the seeds at the bottom;

[0081] The wedge block 74 is provided inside the feeding rack 61 to temporarily block the seeds, so as to reduce the damage of the pushing block 64 to the seeds; when the pushing block 64 is not pushed, the third spring 75 is in a compressed state; when the pushing block 64 is pushed (for compensatory seeding), the pad 76 loses the support of the pushing block 64, so under the rebound action of the third spring 75, the wedge block 74 is pushed to extend between the seeds to be discharged and the seeds at the bottom of the input pipe 63, and drives the second slide bar 73 and the pad 76 to move. After the wedge block 74 is extended, the inclined surface contacts the seeds, and the arc surface at the bottom of the seeds makes the seeds lift upward and break away from the contact with the pushing block 64, thereby avoiding the problem of seed damage; and when the pushing block 64 is reset, the pad 76 is pushed to reset at the same time, and the wedge block 74 is driven to reset by the second slide bar 73, the third spring 75 is compressed again, and the seeds can pass through the input pipe 63 into the through groove 65.

[0082] like Figure 8 and Figure 14 As shown, preferably, a brush 10 is fixedly connected to one side of the inner wall of the seed discharging housing 32 , and the bristles of the brush 10 are in contact with the seed discharging plate 34 .

[0083] A filter structure is provided in the suction hole 35 to prevent the seed coat and debris from being sucked in, but the seed coat and debris are not easy to fall due to gravity in the seeding area. Therefore, a brush 10 is provided in the seeding shell 32. The bristles of the brush are in contact with the suction hole position of the seeding plate 34. During the rotation of the seeding plate 34, the brush 10 moves relative to the brush 10, thereby brushing off the seed coat or debris, reducing the problem of subsequent adsorption instability caused by the debris.

[0084] like Figure 1 and Figure 2 As shown, preferably, the pressing mechanism includes a pressing roller 91 , and a plurality of anti-sticking cloths 92 are fixedly connected to the outer wall of the pressing roller 91 . The anti-sticking cloths 92 are fixedly connected to the outside of the pressing roller 91 in an annular shape and at equal intervals.

[0085] In this embodiment, in the operation scenario of wet or sticky materials (such as wet soil, colloids), the cloth structure can reduce the adhesion between the soil and the metal. The "folding structure" formed by the above-mentioned anti-stick cloth 92 will throw off the soil during rotation, automatically peeling off the residue on the surface of the roller, and maintaining the efficient operation of the equipment.

[0086] While the present invention has been generally described above, modifications and improvements are readily apparent to those skilled in the art. Therefore, modifications and improvements that do not depart from the spirit of the present invention are intended to be within the scope of the present invention.
