Description

Technical Field

[0001] This utility model belongs to the field of agricultural automation technology, and specifically relates to a synchronous fertilization and sowing device for agricultural production. Background Technology

[0002] In modern agricultural production, in order to improve agricultural production efficiency, reduce labor intensity, and adapt to the planting needs of different crops and farmland environments, more and more automated agricultural machinery is being put into use. Large-scale automated agricultural machinery is used in areas with large arable land and flat terrain, while small-scale automated agricultural machinery is needed in areas with small arable land and rugged terrain. Compared with large-scale agricultural machinery, it is cheaper, easier to maintain, and integrates tillage, sowing, and fertilization, thereby improving farming efficiency.

[0003] A search revealed an integrated sowing and fertilization device with prior art patent publication number CN 118058028 A. This device includes a frame, a first sliding rod, a handwheel, a fixed block, a feed box, a sowing assembly, a flattening assembly, and a tillage assembly. The first sliding rod is rotatably connected to the fixed block and passes through it. A handwheel is fixedly connected to one end of the first sliding rod, and a gear is fixedly connected to the other end. A second pulley is fixedly connected to the side of the first sliding rod closest to the fixed block. This invention allows for adjusting the spacing between the two sets of sowing, flattening, and tillage assemblies using the handwheel, accommodating different types of seeds. The device also incorporates a plow blade, which tills the land through left-right and up-down movements. A single plow blade cannot effectively turn the soil or remove stones.

[0004] A search revealed a fertilizer planter with prior art authorization announcement number CN 221488316 U, comprising a traction frame; several storage boxes and several fertilizer boxes are fixedly installed on the traction frame; a first discharge pipe is connected to the storage boxes and is fixedly connected to the traction frame; a support pipe is slidably connected to the first discharge pipe, and a plow is fixedly installed on the support pipe for turning over the soil to form a sowing furrow; a second discharge pipe is connected to the fertilizer boxes, and a fixed pipe is fixedly installed on the support pipe and slidably connected to the second discharge pipe, the fixed pipe for forming the fertilizer furrow; rotating the lever drives the support pipe and the plow to rise and fall, thereby adjusting the depth of the sowing furrow, thus achieving sowing at different depths and improving the flexibility of adjustment; seeds fall from the first discharge pipe through the support pipe into the excavated sowing furrow, and an arc-shaped baffle pushes the soil on both sides of the sowing furrow back into the furrow to bury the seeds; however, this device cannot control the seed sowing spacing, and during the sowing process, multiple seeds may be close together, affecting sowing efficiency. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a synchronous fertilization and sowing device for agricultural production. The tilling mechanism loosens the soil through reciprocating rotation to provide sowing conditions; the sowing mechanism drives the seeds to fall at intervals through a rotating plate to ensure the spacing between seeds and avoid multiple seeds being sown at the same time; the fertilization mechanism controls the output speed of fertilizer through an auger to mix the seeds and fertilizer and deliver them to complete synchronous fertilization and sowing.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A synchronous fertilization and sowing device for agricultural production includes a frame, a tilling mechanism, a sowing mechanism, a fertilization mechanism, wheels, a handle, a traction frame, and a metal plow.

Two sets of wheels are located on both sides of the middle of the frame. The handle is connected to the rear of the frame. A traction frame is located at the front of the frame. A metal plow is located at the center of the lower part of the frame. The synchronous outlet of the fertilization mechanism passes through the metal plow and is located at the center of the metal plow. The rear end of the metal plow is connected to a soil retaining plate via a pin. A counterweight ball is located at the rear end of the soil retaining plate.

[0008] The tilling mechanism includes a motor I, a motor mounting plate, a transmission belt I, a transmission shaft I, a transmission belt II, a transmission shaft II, a connecting rod, a sliding connecting block, a groove I, a gear I, a rack, a groove II, a connecting column, a transmission shaft III, a tilling rake, and a connecting piece. The motor I is mounted on the motor mounting plate, which is mounted on the frame. The motor I is connected to the transmission belt I, which is connected to the transmission shaft I. The transmission shaft I has a transmission belt II, which is connected to the transmission shaft II. The transmission shaft II is connected to one end of the connecting rod, and the other end of the connecting rod is connected to the sliding connecting block. The sliding connecting block has protrusions on both sides and is positioned in the groove I. The inner side of the groove I has a groove that mates with the protrusions on both sides of the sliding connecting block. The groove I is slidably connected to the sliding connecting block. The groove I is connected to the rack via a connecting piece. The rack meshes with the gear I below. The back of the rack has a protrusion, which is positioned in the groove II to make the gear... The rack is slidably connected to the slide groove II, which is set on the connecting column. The connecting column also has a round hole at its lower part. The drive shaft III passes through the round hole at the lower part of the connecting column and is connected to the gear I. The drive shaft III and the connecting column are rotatably connected by bearings. The drive shaft I, drive shaft II, and connecting column are also connected to the frame. The drive shaft I and drive shaft II are rotatably connected to the frame. The tilling rake is fitted on the drive shaft III and rotates together with the drive shaft III. The motor I drives the drive shaft I to rotate through the drive belt I. The drive shaft I drives the drive shaft II to rotate through the drive belt II. The drive shaft II drives the connecting rod to rotate. The connecting rod drives the sliding connecting block to move in the slide groove I. The slide groove I simultaneously drives the rack to reciprocate linearly in the slide groove II. The rack drives the gear I, which meshes with the rack, to reciprocate and rotate. The gear I drives the drive shaft III to reciprocate and rotate. The drive shaft III drives the tilling rake to reciprocate and rotate.

[0009] The sowing mechanism includes a seed inlet, a conical plate, motor II, a transmission belt IV, a guide plate, a support plate, a rotating plate, a wheel, gear II, gear III, motor III, a base, an opening, a seed conveying pipe, a conveying pipe outlet, and a housing. The seed inlet is located at the top of the entire mechanism. Below the seed inlet is the housing, with a conical plate at its center. The conical plate is connected to the housing. Below the conical plate is a rotating plate with a ring of holes around its outer edge. Below the rotating plate is a base with an opening. The seed conveying pipe is located below the opening. Gear II is connected to the lower part of the rotating plate, meshing with gear III. Gear III is connected to motor III. The conveying pipe outlet connects to the synchronous inlet below. Motor III is fixedly connected to the frame. Motor II is located on the upper part of the support plate and is connected to transmission belt IV. The lower part of motor II is connected to a guide plate, which fits against the rotating plate. The support plate is connected to the housing. Transmission belt IV connects multiple sets of guide plates. The outer teeth of the wheel are connected to the rotating plate. The circular holes are meshed and connected to the outer shell via pins. The rotating wheel is located above the opening on the base. When a large number of seeds enter the seed inlet, they are dispersed around the rotating plate by a conical plate, allowing the seeds to enter the circular holes on the outer ring of the rotating plate. Motor III drives gear II to rotate, gear II meshes with gear I, which in turn drives gear I to rotate. Gear I drives the rotating plate to rotate, and the rotating plate drives the seeds in the outer circular holes to rotate. Motor II drives multiple sets of guide plates to rotate via transmission belt IV, guiding and limiting the seeds on the rotating plate below the guide plates to prevent multiple seeds from entering a single circular hole and to ensure even sowing. The rotating plate also drives the rotating wheel to rotate. When the seeds in the circular holes of the rotating plate pass through the rotating wheel, the rotating wheel presses down on the seeds in the circular holes during rotation, preventing the seeds from getting stuck inside the holes. The seeds then enter the seed conveying pipe through the opening on the base and enter the synchronous inlet below through the outlet of the conveying pipe.

[0010] The fertilization mechanism includes a fertilizer box, a fertilizer conveying pipe, an auger, a motor IV, a synchronous outlet, a positioning frame, and a synchronous inlet. The fertilizer box has a fertilizer conveying pipe at its lower part, with the auger inside the pipe. The auger is connected to motor IV, which is located at one end of the pipe. The fertilizer conveying pipe has a synchronous inlet at its upper part and a synchronous outlet at its lower part. The pipe is connected to the positioning frame, which is fixedly connected to the vehicle frame. Fertilizer is placed in the fertilizer box and enters the conveying pipe from within the box. Motor IV controls the auger to rotate, and the auger inside the pipe sends the fertilizer out through the synchronous outlet, which is located behind the metal plow. Seeds entering the conveying pipe through the synchronous inlet are also sent out through the synchronous outlet, completing the sowing and fertilization process.

[0011] The advantages of this utility model compared with the prior art are as follows:

[0012] 1) The motor I of the tilling mechanism drives the transmission shaft I to rotate via the transmission belt I. The transmission shaft I drives the transmission shaft II to rotate via the transmission belt II. The transmission shaft II drives the connecting rod to rotate. The connecting rod drives the sliding connecting block to move in the slide groove I. The slide groove I simultaneously drives the rack to move in the slide groove II, making reciprocating linear motion along the direction of the slide groove II. The rack drives the gear I meshing with the rack to make reciprocating rotational motion through the reciprocating linear motion. The gear I drives the transmission shaft III to make reciprocating rotational motion. The transmission shaft III drives the tilling rake to make reciprocating rotational motion. In the reciprocating rotational motion, the land is turned over, which better loosens the soil and prevents it from being stuck by hard objects such as stones during the tilling process.

[0013] 2) When a large number of seeds enter the seed inlet, the conical plate disperses the seeds around the rotating plate, allowing them to enter the circular holes on the outer ring of the rotating plate. Motor III drives gear II to rotate, gear II meshes with gear I to drive gear I to rotate, gear I drives the rotating plate to rotate, and the rotating plate drives the seeds in the circular holes to rotate. Motor II drives multiple sets of guide plates to rotate and guide the seeds on the rotating plate below the guide plates, preventing multiple seeds from entering a single circular hole and ensuring that there are no seeds in the circular holes, resulting in more even sowing. At the same time, the rotating plate drives the rotating wheel to rotate. When the seeds in the circular holes of the rotating plate pass through the rotating wheel, the rotating wheel presses down on the seeds in the circular holes during rotation, preventing the seeds from getting stuck inside the circular holes, and allowing the seeds to enter the seed delivery pipe through the opening on the base, completing the sowing.

[0014] 3) Place the fertilizer into the fertilizer box, and the fertilizer enters the fertilizer conveying pipe from the box. Motor IV controls the auger to rotate, and the fertilizer is sent out from the synchronous outlet through the auger in the pipe. At the same time, the seeds enter through the synchronous inlet and are also sent out from the synchronous outlet. The seeds and fertilizer are mixed and sent out to complete the synchronous fertilization and sowing. By controlling the speed of motor IV to control the auger, the output speed of fertilizer can be controlled. It can convey both granular fertilizer and traditional fertilizer.

[0030] The sowing mechanism 13 includes a seed inlet 201, a conical plate 202, a motor II 203, a transmission belt IV 204, a guide plate 205, a support plate 206, a rotating plate 207, a rotating wheel 208, a gear II 209, a gear III 210, a motor III 211, a base 212, an opening 213, a seed conveying pipe 214, a conveying pipe outlet 215, and a housing 216. The seed inlet 201 is located at the top of the entire mechanism. Below the seed inlet 201 is the housing 216. The conical plate 202 is located at the center of the housing 216 and is connected to the housing 216. Below the conical plate 202 is the rotating plate 207. The outer ring of the rotating plate 207... A circular hole is provided. A base 212 is provided below the rotating plate 207. An opening 213 is provided on the base 212.

Simultaneously, it is mounted on the outer casing 216 via a pin and rotatably connected to the outer casing 216. The rotating wheel 208 is located above the opening 213 on the base 212. When a large number of seeds enter the seed inlet 201, they are dispersed around the rotating plate 207 by the conical plate 202, allowing the seeds to enter the circular holes on the outer ring of the rotating plate 207. The motor Ⅲ211 drives the gear Ⅱ209 to rotate. The gear Ⅱ209 meshes with gear Ⅰ110, which in turn drives gear Ⅰ110 to rotate. Gear Ⅰ110 then drives the rotating plate 207 to rotate. The seeds inside the outer circular holes are rotated by motor II 203, which drives multiple sets of guide plates 205 to rotate via transmission belt IV 204. This guides and limits the seeds on the rotating plate 207 below the guide plate 205, preventing multiple seeds from entering a single circular hole and ensuring that no seeds are left in the hole, resulting in more even sowing. At the same time, the rotating plate 207 drives the rotating wheel 208 to rotate. When the seeds inside the circular holes of the rotating plate 207 pass through the rotating wheel 208, the rotating wheel 208 presses down on the seeds inside the circular holes during rotation, preventing the seeds from getting stuck inside the holes. The seeds then enter the seed delivery pipe 214 through the opening 213 on the base 212, and then enter the synchronous inlet below through the outlet of the delivery pipe.

[0031] The fertilization mechanism 14 includes a fertilizer tank 301, a fertilizer conveying pipe 302, an auger 303, a motor IV 304, a synchronous outlet 305, a positioning frame 306, and a synchronous inlet 307.

The fertilizer conveying pipe 302 is connected to the positioning frame 306, and the positioning frame 306 is fixedly connected to the vehicle frame 11. Fertilizer is placed into the fertilizer box 301, and the fertilizer enters the fertilizer conveying pipe 302 from the box. The motor IV 304 controls the auger 303 to rotate, and the fertilizer is sent out from the synchronous outlet 305 through the auger 303 in the pipe. The synchronous outlet 305 is set behind the metal plow 18. Seeds that enter the fertilizer conveying pipe 302 from the synchronous inlet 307 are also sent out through the synchronous outlet 305 to complete the sowing and fertilization.

[0032] A synchronous fertilization and seeding device for agricultural production operates as follows:

[0033] The handrail 16 at the rear of the device facilitates manual positioning and docking of the traction frame 17 at the front. The traction frame 17 at the front connects to other power sources, driving the device forward and providing power to the motors on the device. The motor I 101 of the turning mechanism 12 drives the drive shaft I 104 to rotate via the drive belt I 103. The drive shaft I 104 drives the drive shaft II 106 to rotate via the drive belt II 105. The drive shaft II 106 drives the connecting rod 107 to rotate. The connecting rod 107 drives the sliding connecting block 108 to move in the slide groove I 109. Simultaneously, the slide groove I 109 drives the rack 111 to move along the slide groove II 112. The rack 111 moves in a reciprocating linear motion in direction 112. This reciprocating linear motion drives the gear I 110, which meshes with the rack 111, to rotate reciprocally. Gear I 110 drives the transmission shaft III 114 to rotate reciprocally, which in turn drives the tilling rake 115 to rotate reciprocally, completing the tilling process. When a large number of seeds enter the seed inlet 201, they are dispersed around the rotating plate 207 by the conical plate 202, allowing the seeds to enter the circular holes on the outer ring of the rotating plate 207. Motor III 211 drives gear II 209 to rotate, and gear II 209 meshes with gear I 110, which in turn drives gear I 110 to rotate. The rotating plate 207 rotates, causing the seeds inside the outer circular holes to rotate. Motor II 203, via transmission belt IV 204, drives multiple sets of guide plates 205 to rotate, guiding and limiting the seeds on the rotating plate 207 below the guide plates 205. This prevents multiple seeds from entering a single circular hole, ensuring even sowing. Simultaneously, the rotating plate 207 drives the rotating wheel 208 to rotate. As the seeds inside the circular holes of the rotating plate 207 pass through the rotating wheel 208, the rotating wheel 208 presses down on the seeds during its rotation, preventing them from getting stuck inside the holes and allowing them to pass through the opening 21 on the base 212. 3. Seeds enter the seed delivery pipe 214 and pass through the delivery pipe outlet 215 to enter the synchronous inlet 307. Fertilizer is placed in the fertilizer box 301 and enters the fertilizer delivery pipe 302 from the box. Motor IV 304 controls the auger 303 to rotate and send the fertilizer out through the synchronous outlet 305 through the auger 303 in the pipe. Seeds that enter the fertilizer delivery pipe 302 from the synchronous inlet 307 are also sent out through the synchronous outlet 305. Seeds and fertilizer fall synchronously into the furrow opened by the metal plow 18 in front. The metal plow 18 drives the soil retaining plate 19. The soil retaining plate 19 gathers the surrounding soil into a pile through the counterweight ball 20 set behind, completing the sowing and fertilization.
