Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting, in particular to a potato tuber planting water-fertilizer integrated soil covering planting machine and a use method thereof. Background Art

[0002] Potato is an annual herbaceous plant of the genus Solanum in the Solanaceae family. The aboveground stem is diamond-shaped and hairy. Potatoes are high-yielding and nutritious, and are used as food, vegetables, feed, and industrial raw materials. In the southern part of Northeast China, North China, and East China, potatoes have become an important crop for rural prosperity as early spring vegetables; in the southern part of East China and most of South China, potatoes are rotated with rice as winter crops, and the export of fresh potatoes can obtain great economic benefits; in the northwest and southwestern mountainous areas, potatoes play an important role as the main food crop.

[0003] At present, potato planting techniques have been gradually improved in various places. However, due to its own growth characteristics, potatoes need to be planted intermittently. Traditional planting methods mostly use negative pressure to adsorb potato tubers and use gravity free fall to achieve intermittent sowing of potato tubers.

[0004] Since the size of potato tubers is uneven and irregular, when encountering land with complex ground conditions, bumps will cause unstable adsorption of potato tubers or due to the potato tubers themselves, it is easy to cause blockage of potato tuber sowing. Therefore, traditional potato tuber planting equipment cannot stably ensure the equidistant planting of potato tubers, which is easy to cause blockage of potato tuber sowing ports, resulting in holes and missed sowing.

[0005] Existing sowing equipment cannot stably ensure stable and equidistant planting of potato tubers. If the planting density of potato tubers is high, the growth of potato tubers will be greatly affected, which will directly affect the yield of potato tubers. If the planting density of potato tubers is low, the resource utilization rate of land and fertilizers will be reduced, which will easily cause waste of resources. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-8 , the present invention provides a technical solution: In order to realize the intermittent dropping function and anti-blocking function of the device, a potato tuber planting water and fertilizer integrated soil covering planting machine and a method of using the same are proposed, including a machine body 1, a grounding wheel 2, a sowing mechanism 3, and an anti-blocking mechanism 4. A grounding wheel 2 is arranged at the lower end of the machine body 1, the grounding wheel 2 is in contact with the ground, and the grounding wheel 2 is the total kinetic energy input of the present embodiment. A first pulley 301 is fixedly arranged on the grounding wheel 2, and the first pulley 301 is connected to a second pulley 303 in the sowing mechanism 3 through a belt 302. The second pulley 303 is fixedly connected to a sowing wheel 305, and the sowing wheel 305 is rotatably arranged on the machine body 1. In the body 1, intermittent sowing of potato tubers is achieved through the sowing wheel 305, and a fertilizer sowing wheel 314 is fixedly arranged on one side of the sowing wheel 305. The fertilizer sowing wheel 314 is used to achieve simultaneous sowing of fertilizer and potato tubers. An anti-blocking mechanism 4 is arranged above the sowing wheel 305. The L-shaped rod 412 in the anti-blocking mechanism 4 is in contact and connected with the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601. The vibration of the L-shaped rod 412 is used to prevent the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601 from being blocked. The furrowing plow 101 is disassembled and connected to one side of the lower surface of the body 1, and the covering wheel 102 is rotatably arranged on the other side.

[0020] The furrowing plow 101 and the covering wheel 102 adopt the existing technology. The furrowing plow 101 is located in front of the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601, and the covering wheel 102 is located at the rear. The furrowing plow 101 cultivates the land to form furrows for sowing potato tubers, and the covering wheel 102 is used to fill the furrows of potato tubers.

[0021] The sowing mechanism 3 includes a first pulley 301, a sowing wheel 305, and a fertilizer sowing wheel 314. The first pulley 301 is fixedly arranged on one side of the ground wheel 2. One end of the belt 302 is sleeved on the outer surface of the first pulley 301. The other end of the belt 302 is sleeved on the outer surface of the second pulley 303. The second pulley 303 is rotatably arranged on the body 1. One side of the second pulley 303 is fixedly connected to the axis of the rotating shaft 304. The rotating shaft 304 is rotatably arranged in the body 1. The rotating shaft 304 is coaxial with the rotating shaft 304. A sowing wheel 305 is fixedly connected, and the sowing wheel 305 is arranged below the outlet of the tuber bin 501. The sowing wheel 305 is used for sowing potato tubers. An arc-shaped baffle 3051 is fixedly arranged on one side of the sowing wheel 305. The arc-shaped baffle 3051 is used to prevent potato tubers from leaking out of the tuber groove 306 on the sowing wheel 305. In this embodiment, 8 tuber grooves 306 are evenly spaced on the surface of the sowing wheel 305. According to actual sowing requirements, different numbers of tuber grooves 306 can be evenly spaced on the sowing wheel 305. When the tuber groove 306 rotates to below the exit of the tuber bin 501, the potato tubers in the tuber bin 501 fall into the tuber groove 306 one by one due to gravity, and the tuber groove 306 continues to rotate. The potato tubers in the tuber bin 501 stop falling due to the obstruction of the part of the surface of the seeding wheel 305 where the tuber groove 306 is not set. The function of the arc baffle 3051 is to prevent the tuber groove 306 from falling out prematurely. When the tuber groove 306 rotates to be perpendicular to the radial direction of the seeding wheel 305 and downward, the potato tubers fall.

[0022] A top block notch is provided in each tuber groove 306, and one end of a top block 307 is slidably installed in the top block notch. The width of the top block notch is the same as the width of the top block 307. The other end of the top block 307 passes through the mounting ring 308 and is fixedly connected to the wedge block 312. The top block 307 is used to push the potato tubers to prevent the potato tubers from being stuck in the tuber groove 306. A limit block 309 is fixedly provided on the surface of the top block 307. The limit block 309 limits the maximum moving distance of the top block 307. One end of the first spring 310 is fixedly connected to the limit block 309. The other end of the first spring 310 is fixedly connected to the mounting ring 308. The first spring 310 is sleeved on the first damping rod 311 surface, one end of the first vibration damping rod 311 is fixedly connected to the limit block 309, and the other end is fixedly connected to the mounting ring 308, the mounting ring 308 is fixedly arranged in the seeding wheel 305, the surface of the wedge block 312 contacts the surface of the fixing rod 313, and the fixing rod 313 is provided with a wedge surface corresponding to the wedge block 312. When the inclined surface of the fixing rod 313 contacts the inclined surface of the wedge block 312, the fixing rod 313 can apply a thrust to the wedge block 312, so that the wedge block 312 moves, and the fixing rod 313 is fixedly arranged in the body 1, and one end of the fixing rod 313 extends into the seeding wheel 305, and the seeding wheel 305 is provided with a notch corresponding to the fixing rod 313; The limit block 309 limits the maximum moving distance of the top block 307 .

[0023] The positions of the fixed rod 313 and the arc-shaped baffle 3051 are fixed. Under the transmission action of the belt 302, the second pulley 303 rotates, and the second pulley 303 drives the seeding wheel 305 to rotate. When the tuber groove 306 rotates to below the exit of the tuber bin 501, the potato tubers in the tuber bin 501 fall into the tuber groove 306 one by one, and the tuber groove 306 continues to rotate. After rotating half a circle, while the seeding wheel 305 rotates, the top block 307 and the wedge block 312 rotate at the same time, and the wedge block 312 on the top block 307 gradually contacts with the surface of the fixed rod 313. The wedge block 312 is moved away from the fixed rod 313 by the pressure from the inclined surface of the fixed rod 313. The movement of the wedge block 312 pushes the top block 307 to move toward the tuber groove 306. At this time, the first spring 310 and the first damping rod 311 are pushed, the first spring 310 is compressed, and the first damping rod 311 is contracted. In a normal state, the potato tuber will fall freely due to gravity. However, if the potato tuber is stuck in the tuber groove 306, the top block 307 will push the potato tuber stuck in the tuber groove 306 out to prevent the seed from being stuck or missing. The seeding wheel 305 continues to rotate, and the wedge block 312 on the top block 307 in the seeding wheel 305 gradually loses contact with the surface of the fixed rod 313, the first spring 310 and the first damping rod 311 lose thrust and recover, and the first spring 310 and the first damping rod 311 return to the starting position, thereby pushing the top block 307 back to the starting position.

[0024] One side of the seeding wheel 305 is fixedly connected to a fertilizer seeding wheel 314, which is used for seeding fertilizer. The fertilizer seeding wheel 314 is arranged below the outlet of the fertilizer bin 601, and a drop protrusion 315 is arranged on the surface of the fertilizer seeding wheel 314. The fertilizer in the fertilizer bin 601 will fall onto the drop protrusion 315 on the fertilizer seeding wheel 314 due to gravity. A feeding opening 316 is provided at the lower end of the seeding wheel 305 , one end of the feeding opening 316 extends out of the machine body 1 and is fixedly connected to the machine body 1 , and the other end of the feeding opening 316 has a width equal to the sum of the seeding wheel 305 and the fertilizer seeding wheel 314 .

[0025] When the seeding wheel 305 rotates, the fertilizer seeding wheel 314 will rotate simultaneously, and the fertilizer in the fertilizer bin 601 falls between the dropping protrusions 315 on the fertilizer seeding wheel 314. The function of the dropping protrusions 315 is to make the fertilizer fall evenly and to prevent wind. As the fertilizer seeding wheel 314 rotates, the fertilizer and potato tubers fall into the dropping port 316 at the same time and fall into the soil together.

[0026] In order to realize the function of preventing the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601 from being blocked, a potato tuber planting water-fertilizer integrated soil covering planting machine and a method for using the same are proposed. The anti-blocking mechanism 4 comprises: a cam 401, a push rod 408, and an L-shaped rod 412. The cam 401 is coaxially fixed on the rotating shaft 304. A mounting groove 402 is provided on the surface of the cam 401. The inner surface of the mounting groove 402 is in contact with and connected to a driven rod 403. When the cam 401 rotates, the mounting groove 402 applies thrust and pull to the driven rod 403, thereby driving the driven rod 403 to move. The driven rod 403 is fixedly connected to the mounting plate 404. The mounting plate 404 is used to install a sliding plate 405. The mounting plate 404 is fixedly connected to the sliding plate 405. The sliding plate 405 is slidably mounted on the first slide rail 406. Inside, the first slide rail 406 is used for the sliding plate 405 to slide longitudinally. The first slide rail 406 is fixedly arranged in the body 1. First lifting ears 407 are fixedly arranged on both sides of the sliding plate 405. One end of the push rod 408 is hinged on the first lifting ear 407, and the other end of the push rod 408 is hinged on the second lifting ear 409. The second lifting ear 409 is fixedly connected to the sliding rod 410. The sliding rod 410 is slidably installed in the second slide rail 411. One end of the sliding rod 410 away from the sliding plate 405 is fixedly connected to the L-shaped rod 412. The L-shaped rod 412 is used to adapt to the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601 while installing two top plates 413. One side of the two top plates 413 is fixedly connected to the L-shaped rod 412, and the other side of the two top plates 413 are respectively in contact with the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601.

[0027] The tuber bin 501 and the fertilizer bin 601 are fixedly arranged on the body 1. The fertilizer bin 601 is located in the middle of the tuber bin 501 and is filled with fertilizer in a drawer-like manner.

[0028] When the rotating shaft 304 rotates, the cam 401 will rotate accordingly, and the mounting groove 402 on the surface of the cam 401 will rotate at the same time. Since the cam 401 is elliptical, the movement trajectory of the mounting groove 402 is a curve, that is, it fluctuates up and down. Since the driven rod 403 and the mounting groove 402 are in contact and connected, when the long radius of the mounting groove 402 rotates to a direction perpendicular to the axial direction of the rotating shaft 304, the driven rod 403 will be subjected to a thrust from the surface of the mounting groove 402, and the short radius of the mounting groove 402 rotates to a direction perpendicular to the axial direction of the rotating shaft 304. 04 axial direction is vertical, the driven rod 403 will be subjected to the pulling force from the surface of the mounting groove 402, so that the driven rod 403 will reciprocate upward and downward, and the driven rod 403 will drive the sliding plate 405 to slide longitudinally in the first slide rail 406 while moving, and the first ear 407 on the sliding plate 405 moves longitudinally with the sliding plate 405, and the connection end of the first ear 407 and the push rod 408 moves accordingly. The second slide rail 411 is arranged horizontally, so the push rod 408 will push the sliding rod 410 on the second slide rail 411 slides horizontally, and under the action of the slide bar 410, the L-shaped rod 412 will reciprocate horizontally in the same direction, and the L-shaped rod 412 drives the top plate 413 fixedly connected thereto to move. When the top plate 413 moves away from the slide bar 410, it will contact the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601, and knock the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601, so that the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601 vibrate, and the amplitude of the vibration is small, which will not affect the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601 The connection structure of the outlet has no effect on the component structure of the outlet of the tuber bin 501 and the fertilizer bin 601. If the potato tubers and fertilizers in the outlet of the tuber bin 501 or the outlet of the fertilizer bin 601 are blocked, the potato tubers and fertilizer lumps will move slightly under the influence of vibration. Under continuous vibration, the blocked potato tubers or fertilizer lumps will continue to move, thereby unblocking the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601 and preventing blockage in the outlet of the tuber bin 501 or the outlet of the fertilizer bin 601.

[0029] Working principle: First, the device is connected to the working vehicle. When moving forward, the furrowing plow 101 opens a furrow for planting in the land, the ground wheel 2 rotates, and under the action of the belt 302, the second pulley 303 rotates, and the second pulley 303 drives the sowing wheel 305 to rotate. When the tuber groove 306 rotates to below the outlet of the tuber bin 501, the potato tubers in the tuber bin 501 fall into the tuber groove 306 one by one, and the tuber groove 306 continues to rotate. After rotating half a circle, the wedge block 312 on the top block 307 and the fixed rod 3 13 surfaces gradually contact, the wedge block 312 is moved away from the fixing rod 313 by the pressure from the surface of the fixing rod 313, and the wedge block 312 pushes the top block 307 to move toward the tuber groove 306. At this time, the first spring 310 is compressed and the first damping rod 311 is contracted. In a normal state, the potato tuber will fall freely due to gravity and fall into the groove. However, if the potato tuber is stuck in the tuber groove 306, the top block 307 will push the potato tuber stuck in the tuber groove 306 out. When the seeding wheel 305 rotates, the fertilizer seeding wheel 314 will rotate simultaneously, and the fertilizer in the fertilizer bin 601 falls between the dropping protrusions 315 on the fertilizer seeding wheel 314. As the fertilizer seeding wheel 314 rotates, the fertilizer and potato tubers fall into the dropping port 316 at the same time and fall into the soil together.

[0030] When the seeding wheel 305 rotates, the cam 401 rotates accordingly, the mounting groove 402 on the surface of the cam 401 rotates, the driven rod 403 reciprocates upward and downward, the driven rod 403 drives the sliding plate 405 to slide in the first slide rail 406, and the push rod 408 drives the sliding rod 410 to slide in the second slide rail 411. Under the action of the sliding rod 410, the L-shaped rod 412 reciprocates horizontally, and the L-shaped rod 412 drives the top plate 405 fixedly connected thereto to move back and forth. 13 moves, when the top plate 413 moves to a direction away from the slide bar 410, it will contact with the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601, and knock the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601 to make them vibrate. If the potato tubers and fertilizers in the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601 are blocked, the potato tubers and fertilizers will move under the influence of the vibration, thereby unblocking the outlet of the tuber bin 501 and the outlet of the fertilizer bin 601 to prevent blockage.

[0031] The covering wheel 102 is located at the rear. After the planting is completed, the covering wheel 102 fills the furrows and completes the sowing of potato tubers.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

A method for using the potato tuber planting water-fertilizer integrated soil covering planting machine according to any one of claims 1 to 7, characterized in that: The method of use includes the following steps: The first step: the machine body (1) moves forward and uses the furrowing plow (101) to open a furrow for planting on the land, the ground wheel (2) rotates, the belt (302) drives the second pulley (303) and the seeding wheel (305) to rotate simultaneously, the tuber groove (306) rotates to below the outlet of the tuber bin (501), and the potato tubers in the tuber bin (501) fall into the tuber groove (306) one by one. The tuber groove (306) continues to rotate half a circle, the wedge block (312) gradually contacts the surface of the fixed rod (313) and moves in a direction away from the fixed rod (313) under the pressure from the surface of the fixed rod (313), the wedge block (312) pushes the top block (307) to move in the direction of the tuber groove (306), at this time, the first spring (310) is compressed, the first damping rod (311) is contracted, and the top block (307) pushes the potato tubers in the tuber groove (306) out; Step 2: the fertilizer seeding wheel (314) rotates along with the seeding wheel (305), and the fertilizer in the fertilizer bin (601) falls between the drop protrusions (315) on the fertilizer seeding wheel (314). As the fertilizer seeding wheel (314) rotates, the fertilizer and potato tubers fall into the drop opening (316) at the same time and fall into the soil together. The third step: the cam (401) and the mounting groove (402) on its surface rotate with the rotation of the seeding wheel (305), the driven rod (403) performs up and down reciprocating motion and drives the sliding plate (405) to slide in the first slide rail (406), the push rod (408) drives the sliding rod (410) to slide in the second slide rail (411), the sliding rod (410) drives the L-shaped rod (412) to perform lateral reciprocating motion, the L-shaped rod (412) drives the top plate (413) to move and when moving away from the sliding rod (410), it contacts the outlet of the tuber bin (501) and the outlet of the fertilizer bin (601), and the top plate (413) contacts the outlet of the tuber bin (501) and the outlet of the fertilizer bin (601). When the outlet of the tuber bin (501) and the outlet of the fertilizer bin (601) contact each other, a corresponding thrust is applied to the outlet of the tuber bin (501) and the outlet of the fertilizer bin (601), so that the top plate (413) strikes the outlet of the tuber bin (501) and the outlet of the fertilizer bin (601), causing the outlet of the tuber bin (501) and the outlet of the fertilizer bin (601) to vibrate. If the outlet of the tuber bin (501) and the outlet of the fertilizer bin (601) are blocked, the potato tubers and the fertilizer move under the influence of the vibration, thereby unblocking the outlet of the tuber bin (501) and the outlet of the fertilizer bin (601) to prevent blockage. Step 4: The covering wheel (102) is located at the rear. After the planting is completed, the covering wheel (102) fills the gully to complete the sowing of potato tubers.
