Description

Technical Field

[0001] This invention relates to the field of agricultural planting equipment technology, specifically a corn seed quantitative planting gun. Background Technology

[0002] Corn, also known as maize, is an important food and feed crop, widely grown around the world. It thrives in warm, sunny environments, prefers fertile, well-drained soil, and has a high water requirement, especially during the early growth stages and flowering and fruiting periods.

[0003] With the improvement of agricultural technology, a handheld seed gun has been developed to improve sowing efficiency. It is specially designed for sowing small areas or precision crops and can accurately sow seeds into the soil. It is widely used in the sowing of various crops, including corn, wheat, soybeans, and vegetables, to improve sowing efficiency.

[0004] Current seed-planting guns still have shortcomings. When planting corn seeds, pressing or triggering the feed chamber causes the seeds to fall into the pit from the nozzle. Due to the size difference of corn seeds, the number of seeds dispensed each time is insufficient for accurate feeding. At the same time, it is impossible to control the number of seeds planted each time. After planting, excess seeds in the chamber cannot be unloaded. Continuous pressing is required to discharge the seeds from the bottom spout, which is inconvenient for unloading excess seeds and replacing them with other varieties of seeds. These are certain defects. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a corn seed quantitative planter, which has the advantages of automatically improving planting efficiency and solves the current problems of being unable to control the amount of seeds fed and being unable to unload excess seeds from the cavity.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a corn seed quantitative planting gun, comprising a gun body assembly, a feeding assembly, a transmission assembly, a control assembly, and a conveying assembly. The gun body assembly includes a gun body shell, an installation chamber fixed to the side of the gun body shell, a conveying box detachably installed inside the installation chamber, a handle fixed to the gun body shell, a trigger movably connected inside the handle, a planting head fixed to the bottom of the gun body shell, a duckbill hinged to the bottom of the planting head, a handle installed at the top of the gun body shell, and a planting head installed at the bottom. When the trigger is pulled upward, the duckbill unfolds, causing the corn seeds inside to fall into the cleared pit. The corn seeds are stored through the conveying box, which is installed inside the installation chamber to achieve the feeding function.

[0009] The feeding assembly includes a feeding roller movably connected inside the gun body housing, a feeding box attached to the side of the feeding roller, two transmission rings fixed on the feeding roller, tapered teeth provided on the side of the transmission rings, and a first connecting rod fixed on the feeding roller. The bottom of the feeding box has an interface, one side of which is attached to the feeding roller. When the feeding roller rotates, it realizes the function of conveying and discharging corn seeds in the feeding box.

[0010] The transmission assembly includes a transmission disc movably connected to the side of the transmission ring, a transmission cylinder fixed between the transmission discs, and an elastic locking tooth provided at one-quarter of the side of the transmission disc. The elastic locking tooth meshes with the conical locking tooth, and a second connecting rod is fixed on the transmission disc. By rotating the transmission disc, the elastic locking tooth, under the meshing force of the conical locking tooth, causes the transmission ring to drive the conveying roller to rotate, thus realizing the function of feeding and conveying seeds. When the elastic locking tooth disengages from the conical locking tooth, the transmission disc rotates in the opposite direction to reset. At the same time, when the elastic locking tooth on the side contacts the conical locking tooth, it re-engages with the locking tooth on the side of the transmission ring under the elastic force.

[0011] The control assembly includes a stabilizing side plate movably sleeved on the first and second connecting rods. One end of each of the first and second connecting rods is hinged within the gun body housing. A second electric telescopic rod is fixed to one end of the stabilizing side plate. A connecting plate is fixed to the output end of the second electric telescopic rod. A first stabilizing clamp is fixed to one end of the connecting plate. The first stabilizing clamp is slidably connected to the side of the transmission disc. A connecting plate is fixed to the first stabilizing clamp, and a second stabilizing clamp is fixed to the connecting plate. A toothed plate is slidably connected within the second stabilizing clamp, engaging with the side of the conveying cylinder. The stabilizing side plate is L-shaped, with circular holes at both ends matching the diameter of the sides of the first and second connecting rods, improving the stability of the rotation of the conveying roller and the transmission disc. Qualitatively, it ensures the full engagement of the elastic locking teeth and the conical locking teeth. In addition, the first and second connecting rods are movably hinged at the top of the gun body shell, connecting the internal hardware to the shell and preventing the internal hardware from shaking. When the output end of the second electric telescopic rod moves up and down, it adjusts the height of the second stabilizing clamp and the locking tooth plate, and simultaneously moves the trigger connected to the top, expanding or shrinking the length that the trigger can pull, as well as increasing or decreasing the length of engagement between the locking tooth plate and the transmission cylinder. When the trigger is pulled, the angle of rotation of the transmission disc can be controlled each time. Under the transmission operation, the angle of rotation of the material conveying roller increases or decreases, thereby controlling the material conveying speed.

[0012] The feeding assembly includes a feeding pipe fixed inside the gun body shell, and a receiving funnel fixed to the feeding pipe. The receiving funnel is attached to the bottom of the feeding roller, so that when the feeding roller rotates and the corn seeds reach the bottom, the seeds can fall smoothly into the receiving funnel and be fed downwards through the feeding pipe into the pit dug by the duckbill. At the same time, the length of the feeding pipe is three-quarters of the overall length of the gun body shell, and the bottom end corresponds to the center position of the duckbill, so that when the duckbill is in the unfolded state, the seeds in the feeding pipe can be discharged smoothly.

[0013] As a further improvement to the above solution, the seeding gun head has two positioning holes, and a swing rod is movably hinged to the side of the seeding gun head. A positioning spring button is fixed on the swing rod, and the output end of the positioning spring button is inserted into the positioning hole. Meanwhile, an adjustment rod is fixed to one end of the swing rod, and a calibration component is fixed to one end of the adjustment rod. The calibration component includes a contact block fixed inside, a stabilizing rod movably sleeved on the side of the contact block, a storage cylinder movably sleeved on the side of the stabilizing rod, a protective cylinder fixed to the bottom of the storage cylinder, and a protective net fixed on the storage cylinder. Furthermore, a thrust spring is movably sleeved on the side of the stabilizing rod, and the thrust spring is fitted between the contact block and the storage cylinder.

[0014] Through the above technical solution, two positioning holes are opened on each side of the seeding gun head at corresponding positions. One of the positioning holes is set at the horizontal position of the hinge point of the swing rod, and the other positioning hole is set at the vertical position of the hinge point. When the swing rod swings, the rotation path of the positioning spring button corresponds to the positioning hole. In addition, when the duckbill is inserted into the soil, the bottom end of the protective cylinder is attached to the ground. Under the continuous downward pressure, the top end of the storage cylinder is attached to the bottom end of the contact block. Under the impact pressure, the lime in the storage cylinder is discharged from the bottom into the protective cylinder and finally falls on the soil to mark the subsequent pre-drilling position. After the pressure is released, the top of the storage cylinder is separated from the bottom of the contact block by the downward pushing force of the thrust spring.

[0015] As a further improvement to the above solution, a stabilizing rod is fixed between the grip and the seeding gun head.

[0016] Through the above technical solution, the stabilizing rod is fixed between the handle and the seeding gun head by a threaded connection, which improves the overall external stability of the device.

[0017] As a further improvement to the above solution, the outer wall of the conveying roller is provided with a conveying groove in an annular shape. Multiple partitions are fixed in the conveying groove, and multiple spring limiting buttons are fixed in the conveying groove. The spring limiting buttons are located between two adjacent partitions, and a spring push rod is fixed on the conveying box. The output end of the spring push rod corresponds to the inside of the conveying groove.

[0018] Through the above technical solution, the partition divides the feeding trough into multiple small troughs with the same space, and the size of the trough is suitable for standard-sized corn seeds. When the feeding roller rotates, the seeds can enter the trough one by one. At the same time, when the spring push rod contacts the top of the partition, the output end retracts inward. When it is above the trough, the output end pushes the corn seeds into the depth of the trough by the internal spring force, and is locked and fixed by the spring limiting button.

[0019] As a further improvement to the above solution, a plurality of air jet holes are provided in the conveying trough, and the air jet holes are located between two adjacent partitions. At the same time, a plurality of air inlets are provided on the side of the conveying roller, and the air inlets communicate with the air jet holes. Meanwhile, an air jet device is fixed on the receiving funnel and is attached to the side of the conveying roller.

[0020] With the above technical solution, the jetting device is attached to the side of the bottom of the conveying roller. The jetting device has multiple nozzles, which correspond to the air inlet and have settings. Each setting can control a different number of nozzles to jet, so that when the contact head is connected to the air inlet, it can blow the seeds in the corresponding trough out.

[0021] As a further improvement to the above solution, a connecting ring is fixed on the first connecting rod, and a docking ring is movably sleeved on the side of the connecting ring. Multiple reverse locking teeth are fixed inside the connecting ring, and multiple forward locking teeth are fixed inside the docking ring. The reverse locking teeth and the forward locking teeth mesh with each other.

[0022] Through the above technical solution, the meshing action between the reverse and forward clamping teeth, and with the sealing plate attached to the bottom of the conveying box, allows the conveying roller to drive the connecting ring to rotate in the reverse direction. When the conveying roller rotates in the forward direction, the action of the right-angled surfaces of the clamping teeth engaging with each other causes the docking ring to rotate synchronously in the forward direction, causing the sealing plate to disengage from the interface at the bottom of the conveying box, thus achieving the function of unloading.

[0023] As a further improvement to the above solution, a rotating rod is fixed to the side of the docking ring, and a sealing plate is fixed to one end of the rotating rod. The sealing plate is attached to the interface at the bottom of the feeding box.

[0024] With the above technical solution, when the docking ring rotates, the rotating rod drives the sealing plate to rotate simultaneously, thereby opening and sealing the interface at the bottom of the material conveying box.

[0025] As a further improvement to the above solution, a first electric telescopic rod is fixed to one end of the stabilizing side plate, and a resistance plate is fixed to the output end of the first electric telescopic rod, with the resistance plate meshing on the transmission ring.

[0026] Through the above technical solution, the inner side of the resistance plate has a locking tooth, which is designed in the opposite direction to the locking tooth on the transmission ring, restricting the transmission ring to rotate only in the forward direction. When unloading, it is necessary to control the output end of the first electric telescopic rod to extend so that the resistance plate is disengaged from the transmission ring, so that when the transmission disc rotates in the forward direction, the conveying roller can rotate in the reverse direction.

[0027] As a further improvement to the above solution, a stabilizing sleeve is fixed on the connecting plate, and a first slide rod and a second slide rod are movably sleeved inside the stabilizing sleeve. One end of the first slide rod and the second slide rod are movably hinged, while the other end of the first slide rod is fixed with a connecting plate. One end of the connecting plate is fixed to the toothed plate, and a tension spring is movably sleeved on the side of the first slide rod. The tension spring is attached between the stabilizing sleeve and the connecting plate.

[0028] Through the above technical solution, the tension spring is used to push the connecting plate to move downward. When the trigger is lifted upward, the locking plate moves upward. At this time, the tension spring tightens and the transmission cylinder rotates in the forward direction. When the trigger is not under force, the locking plate automatically resets under the push of the tension spring, and the transmission cylinder resets in the reverse direction. At this time, the elastic locking teeth and the conical locking teeth mesh again.

[0029] As a further improvement to the above solution, a stabilizing protrusion is provided inside the stabilizing sleeve, and a stabilizing groove is provided on the side of the first slide rod and the second slide rod along their length direction. The stabilizing groove is slidably connected to the side of the stabilizing protrusion, and an adjustment knob is fixed at one end of the second slide rod. The adjustment knob is movably hinged to the trigger.

[0030] Through the above technical solution, the stabilizing grooves of the first and second slide rods are staggered, preventing the second slide rod from passing through the stabilizing sleeve. This allows the toothed plate to move up and down to the length of the first slide rod. When the trigger is pulled upward, the lower half of the toothed plate engages with the transmission cylinder, achieving normal sowing. Under the push of the tension spring, it achieves a reset function. When the stabilizing grooves of the two slide rods are opposite each other, the second slide rod can pass through the stabilizing sleeve. Under the push of the tension spring, the upper half of the toothed plate engages with the transmission cylinder, causing the transmission cylinder to rotate in the opposite direction. This allows the sealing plate to disengage from the interface at the bottom of the feeding box, achieving the unloading function.

[0031] Compared with the prior art, the present invention provides a corn seed quantitative planting gun, which has the following beneficial effects:

[0032] 1. This corn seed quantitative planting gun has a feeding trough on the feeding roller. The feeding trough is divided into multiple troughs with the same space by a partition. When the feeding roller rotates, the corn seeds enter the corresponding trough one by one and are fixed by the spring limit button. When the trough containing seeds reaches the bottom position, the air jet device operates, and gas is sprayed out from the air jet hole in the trough, causing the seeds to detach from the trough, fall into the receiving funnel, and be discharged from the bottom. This achieves accurate quantitative planting and effectively improves planting efficiency.

[0033] 2. This corn seed quantitative planting gun, when the feeding roller rotates in the forward direction, the connecting ring and the docking ring are engaged by the interlocking teeth, so that the docking ring rotates synchronously with the feeding roller, thereby causing the sealing plate to disengage from the interface at the bottom of the feeding box, so that excess seeds inside can be discharged from the box. Furthermore, the design of the device box and the installation chamber being detachable facilitates the removal and cleaning of the box.

[0034] 3. This corn seed quantitative planter features a swing rod hinged to the side of the planter head. An adjustment rod is mounted on the swing rod, and a calibration component is vertically mounted at the front end of the adjustment rod. When the nozzle is inserted into the soil, the protective sleeve at the bottom of the calibration component adheres to the soil. Under continuous downward pressure, the lime in the storage cylinder is sprayed from the bottom onto the soil, thus presetting the position for secondary planting and achieving equidistant planting. The swing rod can swing and is fixed in place by inserting a positioning spring button into the positioning hole, facilitating the folding and storage of the adjustment rod.

[0035] 4. This corn seed quantitative planter shortens the length of the feed tube within the gun body assembly compared to the traditional internal feed tube. Furthermore, by inserting the feed tube into the soil with the duckbill closed and then opening it with a trigger, the soil is dispersed, preventing the feed tube from contacting the soil. This effectively avoids soil clogging the tube and solves the problem of soil entering the cavity and clogging the feed tube when the feed tube of a press-type planter is pressed to half its length and the duckbill opens, under continuous pressing.

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Example 1

[0057] Please see Figure 1-13As shown, the corn seed quantitative planter proposed in this embodiment includes a gun body assembly 1, a feeding assembly 2, a transmission assembly 3, a control assembly 4, and a conveying assembly 5. The gun body assembly 1 includes a gun body shell 101, a mounting chamber 102 fixed to the side of the gun body shell 101, a conveying box 103 detachably installed in the mounting chamber 102, a handle 104 fixed to the gun body shell 101, a trigger 105 movably connected inside the handle 104, and a planting head 106 fixed to the bottom of the gun body shell 101. A duckbill 108 is movably hinged to the bottom of the planting head 106. A handle 104 is installed at the top of the device 1, and a seeding nozzle 106 is installed at the bottom. When the trigger 105 is pulled upward, the duckbill 108 is opened, and the corn seeds inside fall into the pit. The corn seeds are stored through the feeding box 103. The feeding box 103 is installed in the installation chamber 102 to realize the function of feeding. The top and bottom of the installation chamber 102 are interconnected. When the bottom interface of the feeding box 103 is closed by the sealing plate 210, the seeds are prevented from being discharged. When the sealing plate 210 is detached from the feeding box 103, it is convenient to discharge the material in the installation chamber 102.

[0058] The feeding assembly 2 includes a feeding roller 201 movably connected inside the gun housing 101, a feeding box 103 attached to the side of the feeding roller 201, and two transmission rings 211 fixed on the feeding roller 201. The side of the transmission ring 211 is provided with a conical tooth 212, and a first connecting rod 206 is fixed on the feeding roller 201. The bottom of the feeding box 103 has an interface, one side of which is attached to the feeding roller 201. When the feeding roller 201 rotates, it realizes the function of conveying and feeding corn seeds in the feeding box 103.

[0059] The transmission assembly 3 includes a transmission disc 301 movably connected to the side of the transmission ring 211. A transmission cylinder 302 is fixed between the transmission discs 301. An elastic tooth 303 is provided at one-quarter of the side of the transmission disc 301. The elastic tooth 303 meshes with the conical tooth 212. A second connecting rod 304 is fixed on the transmission disc 301. When the transmission disc 301 rotates, the elastic tooth 303, under the force of meshing with the conical tooth 212, causes the transmission ring 211 to drive the conveying roller 201 to rotate in the same direction, thus realizing the function of feeding and conveying seeds. When the elastic tooth 303 disengages from the conical tooth 212, the transmission disc 301 rotates in the opposite direction to reset. At the same time, when the elastic tooth 303 on the side contacts the conical tooth 212, under the elastic force, it re-meshes with the tooth on the side of the transmission ring 211.

[0060] The control assembly 4 includes a stabilizing side plate 401 movably sleeved on the first connecting rod 206 and the second connecting rod 304. One end of each of the first and second connecting rods is hinged within the gun body housing 101. A second electric telescopic rod 404 is fixed to one end of the stabilizing side plate 401. A connecting plate 405 is fixed to the output end of the second electric telescopic rod 404. A first stabilizing clamping plate 406 is fixed to one end of the connecting plate 405. The first stabilizing clamping plate 406 is slidably connected to the side of the transmission disc 301. A connecting plate 407 is fixed to the first stabilizing clamping plate 406. A second stabilizing clamping plate 408 is fixed to the connecting plate 407. A toothed plate 409 is slidably connected within the second stabilizing clamping plate 408. The toothed plate 409 engages with the side of the conveying cylinder 302. The stabilizing side plate 401 is L-shaped, and both ends have circular holes matching the diameter of the sides of the first and second connecting rods, thus raising the conveying roller 2. The stability of the rotation of the transmission disc 301 and the transmission disc 301 is ensured, and the elastic locking teeth 303 and the conical locking teeth 212 are fully engaged. In addition, the first and second connecting rods are movably hinged to the top of the gun body shell 101, which realizes the connection between the internal hardware and the shell, and avoids the shaking of the internal hardware. When the output end of the second electric telescopic rod 404 moves up and down, it realizes the adjustment of the height of the second stabilizing clamp 408 and the locking tooth plate 409. At the same time, it makes the trigger 105 connected to the top move synchronously, expanding or shrinking the length that the trigger 105 can pull, and increasing or decreasing the length of engagement between the locking tooth plate 409 and the transmission cylinder 302. When the trigger 105 is pulled, the angle of rotation of the transmission disc 301 can be controlled each time. Under the transmission operation, the angle of rotation of the material conveying roller 201 increases or decreases, thereby controlling the speed of material conveying.

[0061] The feeding assembly 5 includes a feeding pipe 501 fixed inside the gun body shell 101. A receiving funnel 502 is fixed to the feeding pipe 501. The receiving funnel 502 is attached to the bottom of the feeding roller 201, so that when the feeding roller 201 rotates, the corn seeds can fall smoothly into the receiving funnel 502 when they reach the bottom. The seeds are then fed down into the pit opened by the duckbill 108 through the feeding pipe 501. At the same time, the length of the feeding pipe 501 is three-quarters of the overall length of the gun body shell 101, and the bottom end corresponds to the center position of the duckbill 108. This allows the seeds in the feeding pipe 501 to be discharged smoothly when the duckbill 108 is in the unfolded state.

[0062] The working principle of the corn seed quantitative planting gun proposed in this embodiment is as follows: During use, the feeding box 103 is inserted into the installation chamber 102, so that one side of the feeding box 103 interface is attached to the feeding roller 201, and the output end of the spring push rod 1031 is attached to the feeding trough 202. Then, corn seeds are poured into the feeding box 103. By pulling the trigger 105, the duckbill 108 is spread out in the soil. Simultaneously, the second slide rod 413 and the first slide rod 412 drive the toothed plate 409 to move upwards through the connecting plate 414 at the bottom. At this time, under the action of the toothed plate 409 meshing with the transmission cylinder 302, the transmission cylinder 302 rotates clockwise, and through the elastic toothed plate 303 on the side of the transmission disc 301 and the transmission ring 2... Under the engagement of the side conical locking teeth 212, the conveying roller 201 rotates in the reverse direction, causing the corn seeds at the bottom interface of the conveying box 103 to enter the conveying trough 202 isolated by the partition 2021 one by one (at this time, the seeds are above the spring limiting button 203). When the seeds reach the top as the conveying roller 201 rotates, the output end of the spring push rod 1031 contacts the partition 2021, and the internal spring tightens. When entering the next trough, the spring pushes the output end of the push rod, causing the output end to push the seeds deep into the trough and lock them in place by the spring limiting button 203 (at this time, the output end of the spring limiting button 203 is attached to the side of the corn seed). As the conveying roller 201 continues to rotate... When the seeds reach the bottom while the machine is rotating, the number of nozzles activated on the jet spray device 503 is adjusted. After pulling the trigger, the jet spray device 503 automatically starts, spraying air into the aligned air inlet 205. This causes the air to exit from the jet outlet 204, causing the corn seeds in the corresponding trough to fall into the receiving funnel 502 and be discharged into the soil from the bottom of the conveying pipe 501. After sowing is complete, releasing the trigger 105 causes the toothed plate 409 to reset under the push of the tension spring 417. At the same time, the transmission disc 301 rotates in the opposite direction and re-engages with the transmission ring 211. The above steps are repeated to achieve continuous sowing. When clearing and unloading the conveying box 103, the first electric telescopic rod 402 is controlled to... The outlet extends, causing the resistance plate 403 to disengage from the transmission ring 211. At this time, the conveying roller 201 can rotate in the forward direction. Then, by rotating the control knob 416, the stabilizing grooves 415 opened by the first and second slide rods are aligned. Under the push of the tension spring 417, the second slide rod 413 can pass through the stabilizing sleeve 410, so that the teeth of the upper part of the toothed plate 409 mesh with the transmission cylinder 302. The transmission cylinder 302 drives the transmission disc 301 to rotate in the forward direction, causing the conveying roller 201 to rotate in the reverse direction. At this time, under the reverse engagement of the reverse toothed plate 2071 and the forward toothed plate 2081, the docking ring 208 is driven to rotate in the reverse direction at the same time, so that the sealing plate 210 disengages from the interface at the bottom of the conveying box 103, thereby clearing the cavity and discharging the material.

[0063] Example 2

[0064] Please see Figure 1 , 6 As shown in Figure 13, the corn seed quantitative planter proposed in this embodiment, based on Embodiment 1, further includes two positioning holes 109 on the planter head 106. A swing rod 110 is movably hinged to the side of the planter head 106, and a positioning spring button 111 is fixed on the swing rod 110. The output end of the positioning spring button 111 is inserted into the positioning hole 109. A control rod 112 is fixed to one end of the swing rod 110, and a calibration component 11 is fixed to one end of the control rod 112. 3. The calibration component 113 includes a contact block 1131 fixed inside, a stabilizing rod 1132 movably sleeved on the side of the contact block 1131, a storage cylinder 1133 movably sleeved on the side of the stabilizing rod 1132, a protective cylinder 1134 fixed at the bottom of the storage cylinder 1133, a protective net 1135 fixed on the storage cylinder 1133, and a thrust spring 1136 movably sleeved on the side of the stabilizing rod 1132, the thrust spring 1136 being fitted between the contact block 1131 and the storage cylinder 1133.

[0065] More specifically, two positioning holes 109 are provided on each side of the seeding gun head 106 at corresponding positions. One of the positioning holes 109 is located at the horizontal position of the hinge point of the swing rod 110, while the other positioning hole 109 is located at the vertical position of the hinge point. When the swing rod 110 swings, the rotation path of the positioning spring button 111 corresponds to the positioning hole 109. In addition, when the duckbill 108 is inserted into the soil, the bottom end of the protective cylinder 1134 is attached to the ground. Under continuous downward pressure, the top end of the storage cylinder 1133 is attached to the bottom end of the contact block 1131. Under the impact pressure, the lime in the storage cylinder 1133 passes through the protective net 1135 and is discharged from the bottom into the protective cylinder 1134, eventually falling on the soil to mark the subsequent pre-drilled hole position. After the pressure is released, the top of the storage cylinder 1133 is separated from the bottom of the contact block 1131 by the downward pushing force of the thrust spring 1136.

[0066] Furthermore, a stabilizing rod 114 is fixed between the grip 104 and the seed gun head 106.

[0067] More specifically, the stabilizing rod 114 is fixed between the handle 104 and the seed gun head 106 by a threaded connection, which improves the overall external stability of the device.

[0068] Example 3

[0069] Please see Figure 1-12As shown, the corn seed quantitative planting gun proposed in this embodiment, based on the first embodiment, further includes a feeding groove 202 annularly opened on the outer wall of the feeding roller 201. Multiple partitions 2021 are fixed in the feeding groove 202, and multiple spring limiting buttons 203 are fixed in the feeding groove 202. The spring limiting buttons 203 are arranged between two adjacent partitions 2021, and a spring push rod 1031 is fixed on the feeding box 103. The output end of the spring push rod 1031 corresponds to the inside of the feeding groove 202.

[0070] More specifically, the partition 2021 divides the feeding trough 202 into multiple small troughs with the same space, and the size of the trough is suitable for standard-sized corn seeds. When the feeding roller 201 rotates, the seeds can enter the trough one by one. At the same time, when the spring push rod 1031 contacts the top of the partition 2021, the output end retracts inward. When it is above the trough, the output end pushes the corn seeds into the depth of the trough by the internal spring force, and is locked and fixed by the spring limiting button 203.

[0071] Furthermore, the material conveying trough 202 is provided with a plurality of air jet holes 204, which are located between two adjacent partitions 2021. At the same time, the side of the material conveying roller 201 is provided with a plurality of air inlets 205, which are interconnected with the air jet holes 204. Meanwhile, the receiving funnel 502 is fixed with an air jet device 503, which is attached to the side of the material conveying roller 201.

[0072] More specifically, the jetting device 503 is attached to the side of the bottom end of the conveying roller 201. The jetting device 503 has multiple nozzles, which correspond to the air inlet 205 and have settings. Each setting can control a different number of nozzles to jet, so that when the contact head is connected to the air inlet 205, it can blow the seeds in the corresponding tank out.

[0073] Please refer to Figure 2 for details. A connecting ring 207 is fixed on the first connecting rod 206. A docking ring 208 is movably sleeved on the side of the connecting ring 207. Multiple reverse teeth 2071 are fixed inside the connecting ring 207, while multiple forward teeth 2081 are fixed inside the docking ring 208. The reverse teeth 2071 and the forward teeth 2081 mesh with each other.

[0074] More specifically, through the meshing action between the reverse clamping teeth 2071 and the forward clamping teeth 2081, and with the sealing plate 210 attached to the bottom of the conveying box 103, the conveying roller 201 can normally drive the connecting ring 207 to rotate in the reverse direction. When the conveying roller 201 rotates in the forward direction, the right-angled surfaces of the clamping teeth are attached to each other, causing the docking ring 208 to rotate synchronously in the forward direction, so that the sealing plate 210 is disengaged from the interface at the bottom of the conveying box 103, thus achieving the function of unloading.

[0075] Furthermore, a rotating rod 209 is fixed to the side of the docking ring 208, and a sealing plate 210 is fixed to one end of the rotating rod 209. The sealing plate 210 is attached to the interface at the bottom of the material conveying box 103.

[0076] More specifically, when the docking ring 208 rotates, it drives the sealing plate 210 to rotate simultaneously via the rotating rod 209, thereby opening and sealing the interface at the bottom of the material conveying box 103.

[0077] Furthermore, a first electric telescopic rod 402 is fixed to one end of the stabilizing side plate 401, and a resistance plate 403 is fixed to the output end of the first electric telescopic rod 402. The resistance plate 403 is engaged with the transmission ring 211.

[0078] More specifically, the inner side of the resistance plate 403 has locking teeth, which are designed in the opposite direction to the locking teeth on the transmission ring 211, restricting the transmission ring 211 to rotate only in the forward direction. When unloading, the output end of the first electric telescopic rod 402 needs to be extended to make the resistance plate 403 disengage from the transmission ring 211, so that when the transmission disc 301 rotates in the forward direction, the conveying roller 201 can rotate in the reverse direction.

[0079] Furthermore, a stabilizing sleeve 410 is fixed on the connecting plate 407. A first sliding rod 412 and a second sliding rod 413 are movably sleeved inside the stabilizing sleeve 410. One end of the first sliding rod 412 and the second sliding rod 413 are movably hinged. At the same time, a connecting plate 414 is fixed to the other end of the first sliding rod 412. One end of the connecting plate 414 is fixed to the toothed plate 409. A tension spring 417 is movably sleeved on the side of the first sliding rod 412. The tension spring 417 is attached between the stabilizing sleeve 410 and the connecting plate 414.

[0080] More specifically, the tension spring 417 is used to push the connecting plate 414 downward. When the trigger 105 is lifted upward, the toothed plate 409 moves upward. At this time, the tension spring 417 tightens and the transmission cylinder 302 rotates in the forward direction. When the trigger 105 is not under force, the toothed plate 409 automatically resets under the push of the tension spring 417, and the transmission cylinder 302 resets in the reverse direction. At this time, the elastic toothed plate 303 and the conical toothed plate 212 engage again.

[0081] Furthermore, a stabilizing protrusion 411 is provided inside the stabilizing sleeve 410. At the same time, a stabilizing groove 415 is provided on the side of the first slide rod 412 and the second slide rod 413 along its length direction. The stabilizing groove 415 is slidably connected to the side of the stabilizing protrusion 411. And one end of the second slide rod 413 is fixed with an adjustment knob 416, which is movably hinged to the trigger 105.

[0082] More specifically, the stabilizing grooves 415 of the first and second slide rods are staggered, preventing the second slide rod 413 from passing through the stabilizing sleeve 410. This allows the toothed plate 409 to move up and down to the same height as the first slide rod 412. When the trigger is pulled upwards, the lower half of the toothed plate 409 engages with the transmission cylinder 302, achieving normal sowing. Under the push of the tension spring 417, it achieves a reset function. When the stabilizing grooves 415 of the two slide rods are opposite each other, the second slide rod 413 can pass through the stabilizing sleeve 410. Under the push of the tension spring 417, the upper half of the toothed plate 409 engages with the transmission cylinder 302, causing the transmission cylinder 302 to rotate in the opposite direction. This allows the sealing plate 210 to disengage from the interface at the bottom of the feeding box 103, achieving the unloading function.

[0083] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
