Description

Technical Field

[0001] The present invention relates to the technical field of fertilizing and planting devices, and in particular to an intelligent fertilizing and planting device with a plant spacing adjustment function. Background Art

[0002] The fertilization and planting device is a mechanical device used in the fertilization process of agricultural planting, which is designed to simplify the fertilization process during planting and improve the accuracy and efficiency of fertilization. The device works together through a series of components to automatically or semi-automatically apply fertilizer to the soil near the roots of plants, thereby promoting the healthy growth of plants.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] Embodiment 1, as Figures 1 to 3 As shown, the present invention proposes an intelligent fertilization and planting device with a plant spacing adjustment function, including a frame, and also includes two support beams 1 fixedly mounted on the frame, a plurality of supports 101 are mounted between the two support beams 1, and a first distance adjustment mechanism for equidistantly adjusting the distance between two adjacent supports 101 is mounted on one of the support beams 1. Among them, the support 101 located in the middle is fixedly connected to the two support beams 1, and the other supports 101 are slidably connected to the support beam 1. The first adjustment mechanism allows the plurality of supports 101 to move closer to or farther from each other based on the support 101 in the middle.

[0036] Furthermore, the first distance adjusting mechanism includes a first connecting block 2 fixedly mounted on the support beam 1, wherein sliding rods 201 are fixedly mounted on both sides of one of the support beams 1, and distance adjusting plates 202 are slidably mounted on the two sliding rods 201, and multiple second connecting blocks 203 are slidably mounted on the distance adjusting plates 202, and first connecting rods 204 are rotatably mounted on both ends of the second connecting blocks 203, and the first connecting rod 204 is rotatably connected to the adjacent first connecting block 2, and a first screw rod 205 is rotatably mounted on one of the support beams 1, and the distance adjusting plate 202 is threadedly connected to the first screw rod 205. By rotating the first screw rod 205, the distance adjusting plate 202 can be driven to move along the sliding rod 201, so that the multiple second connecting blocks 203 can slide on the distance adjusting plate 202 while the distance adjusting plate 202 moves. The transmission of the first connecting rod 204 can drive the multiple first connecting blocks 2 to move. The moving first connecting block 2 will drive the support 101 to move, so that the multiple supports 101 can move synchronously and the distance between two adjacent supports 101 can always be kept equal. The spacing between two adjacent supports 101 can be adjusted according to the planting requirements of different plants.

[0037] like Figures 4 to 8 As shown, this embodiment also includes a plurality of support wheels 301 that are rotatably mounted on one of the support beams 1 and in contact with the ground, a seed delivery tube 4 and a fertilizer delivery tube 401 are mounted on the support 101, and two independent hoppers for seeds and waste are mounted on the frame, and the seeds will enter the seed delivery tube 4. Fertilizer will enter the fertilizer delivery tube 401 (the hopper is not drawn in the figure, this is the prior art and will not be described here). A second distance adjustment mechanism that is linked to the support wheel 301 is mounted on the frame, and the second distance adjustment mechanism controls the periodic opening and closing of the seed delivery tube 4 and the fertilizer delivery tube 401, and controls the time interval between two adjacent openings and closings of the seed delivery tube 4 and the fertilizer delivery tube 401. When the seed delivery tube 4 and the fertilizer delivery tube 401 are opened once, seeds and fertilizers can be input into the ground once, and the distance between two adjacent seeds can be controlled by controlling the time of each opening and closing. A support shaft 3 is rotatably mounted on one of the support beams 1, and the support wheel 301 is fixedly mounted on the support shaft 3. The support wheel 301 will contact the ground, the frame will be connected to the tractor, and the support wheel 301 will rotate as the frame moves.

[0038] Furthermore, the second distance adjusting mechanism includes a feed box 402 fixedly mounted on the seed pipe 4 and the fertilizer pipe 401, a feed pipe 403 fixedly mounted on the feed box 402, a transfer wheel 404 rotatably mounted in the feed box 402, the edge of the transfer wheel 404 abuts against the inner wall of the feed box 402, and a plurality of transfer troughs 405 are provided on the transfer wheel 404, the upper and lower ends of the feed box 402 are respectively connected with the feed pipe 403 and the seed pipe 4 or the fertilizer pipe 401, when the transfer wheel 404 rotates, the transfer trough 405 on the transfer wheel 404 will be periodically connected with the feed pipe 403, at this time, the seeds or fertilizers will enter the transfer trough 405, the number of seeds and the quality of the fertilizer entering at a single time depends on the size of the transfer trough 405, when the transfer trough 405 rotates to be connected with the seed pipe 4 or the fertilizer pipe 401, the seeds or materials will enter the seed pipe 4 or the fertilizer pipe 401, so that the seeds and fertilizers flow into the ground. The seed conveying pipe 4 and the fertilizer conveying pipe 401 are provided with a transmission assembly installed on the frame, which drives the transfer wheel 404 to rotate as the support wheel 301 rotates.

[0039] It should be noted that two adjacent transfer wheels 404 are connected by a telescopic connecting rod 415, so that multiple transfer wheels 404 can rotate synchronously.

[0040] Further, the transmission assembly includes a linkage belt 406 fixedly mounted on the two transfer wheels 404, a first pulley 407 fixedly mounted on the support shaft 3, a tensioning wheel 408 rotatably mounted on one of the support beams 1, a first telescopic rod 413 fixedly mounted on one of the pulleys of the linkage belt 406, a second pulley 411 fixedly mounted on the first telescopic rod 413, a transmission belt 412 connected to the first pulley 407, the tensioning wheel 408 and the second pulley 411, and a transmission ratio adjustment assembly for adjusting the diameter of the second pulley 411 installed on the second pulley 411. When the support wheel 301 rotates, the first pulley 407 will be driven to rotate, the rotating first pulley 407 will drive the second pulley 411 to rotate through the transmission belt 412, the rotating second pulley 411 will drive the linkage belt 406 to rotate through the first telescopic rod 413, and the rotating linkage belt 406 can drive the two transfer wheels 404 to rotate.

[0041] Furthermore, an optical axis 409 is slidably mounted on one of the support beams 1, a wheel seat 410 is fixedly mounted on the optical axis 409, a spring 414 is fixedly mounted on the wheel seat 410, the other end of the spring 414 is fixedly connected to the support beam 1, and the tensioning wheel 408 rotates on the wheel seat 410. Through the elastic force of the spring 414, the wheel seat 410 can drive the tensioning wheel 408 to expand outward, and then the transmission belt 412 can always be kept in a tensioned state through the tensioning wheel 408, thereby ensuring the transmission stability of the transmission belt 412.

[0042] It should be noted that the second pulley 411 includes two side plates 4111, and a rotating wheel 4112 is rotatably installed between the two side plates 4111, one of the side plates 4111 is fixedly connected to the first telescopic rod 413, and the transmission ratio adjustment assembly includes a plurality of tensioning blocks 4113 slidably installed between the two side plates 4111, a second connecting rod 4114 is rotatably installed on the tensioning block 4113, the other end of the second connecting rod 4114 is rotatably connected to the rotating wheel 4112, a clamping wheel 4115 is fixedly installed on the rotating wheel 4112, and a plurality of limiting grooves 4116 are provided on the clamping wheel 4115, a second screw rod 4117 is rotatably installed on the side plate 4111, a limiting block 4118 is rotatably installed on the second screw rod 4117, and the limiting block 4118 is slidably connected to the side plate 4111. When the distance between two adjacent seeds during sowing needs to be changed, the transmission ratio between the first belt pulley 407 and the second belt pulley 411 needs to be adjusted. At this time, the diameter of the circle formed by the multiple tensioning blocks 4113 can be adjusted.

[0043] When adjusting the diameter of the circle formed by the multiple tensioning blocks 4113, first rotate the second screw rod 4117 to drive the limit block 4118 to disengage the limit groove 4116. At this time, the clamping wheel 4115 will be able to rotate relative to the side plate 4111. At this time, hold the two side plates 4111 and rotate the clamping wheel 4115 to drive the rotating wheel 4112 to rotate. The rotating wheel 4112 will drive the multiple second connecting rods 4114 to rotate, thereby driving the multiple tensioning blocks 4113 to expand outward or contract inward, thereby changing the size of the circle formed by the multiple tensioning blocks 4113. Since the transmission belt 412 is overlapped on the circle formed by the multiple tensioning blocks 4113, the transmission ratio between the first pulley 407 and the second pulley 411 can be changed, thereby changing the distance between two adjacent seeds.

[0044] Working principle: Rotating the first screw rod 205 can drive the distance adjusting plate 202 to move along the sliding rod 201, so that the multiple second connecting blocks 203 can slide on the distance adjusting plate 202 while the distance adjusting plate 202 moves. The transmission of the first connecting rod 204 can drive the multiple first connecting blocks 2 to move. The moving first connecting block 2 will drive the support 101 to move, so that the multiple supports 101 can move synchronously and the distance between two adjacent supports 101 can always be kept equal. The spacing between two adjacent supports 101 can be adjusted according to the planting requirements of different plants.

[0045] When the support wheel 301 rotates, it will drive the first pulley 407 to rotate, and the rotating first pulley 407 will drive the second pulley 411 to rotate through the transmission belt 412, and the rotating second pulley 411 will drive the linkage belt 406 to rotate through the first telescopic rod 413, and the rotating linkage belt 406 can drive the two transfer wheels 404 to rotate. The transfer trough 405 on the transfer wheel 404 will be periodically connected with the feed pipe 403, and at this time, the seeds or fertilizers will enter the transfer trough 405. The number of seeds and the quality of fertilizers entering at a time depend on the size of the transfer trough 405. When the transfer trough 405 rotates to communicate with the seed delivery pipe 4 or the fertilizer delivery pipe 401, the seeds or materials will enter the seed delivery pipe 4 or the fertilizer delivery pipe 401, so that the seeds and fertilizers flow into the ground.

[0046] Rotating the card wheel 4115 can drive the rotating wheel 4112 to rotate, and the rotating wheel 4112 will drive multiple second connecting rods 4114 to rotate, thereby driving multiple tensioning blocks 4113 to expand outward or contract inward, thereby changing the size of the circle formed by the multiple tensioning blocks 4113. Since the transmission belt 412 is overlapped on the circle formed by the multiple tensioning blocks 4113, the transmission ratio between the first pulley 407 and the second pulley 411 can be changed, thereby changing the distance between two adjacent seeds.

[0047] Embodiment 2, as Figures 9 to 11 As shown, based on the first embodiment, a second telescopic rod 5 is fixedly mounted on the support 101, a slotted block 501 is fixedly mounted on the second telescopic rod 5, a third screw rod 503 is fixedly mounted on the slotted block 501, a first internal threaded rod 502 is rotatably mounted on the support 101, the first internal threaded rod 502 is threadedly connected with the third screw rod 503, and the seed delivery tube 4 is fixedly mounted on the slotted block 501. By making the slotted block 501 contact the ground, when the device moves with the tractor, a groove can be cultivated on the ground by the slotted block 501, and the original soil in the groove at this time will be distributed on both sides of the groove. By rotating the first internal threaded rod 502, the slotted block 501 can be driven to rise and fall, and then the depth of the groove cultivated by the slotted block 501 can be adjusted to adapt to the depth of the groove required to be cultivated when sowing different seeds, and the seeds will enter the inside of the groove.

[0048] In this embodiment, a graded soil covering component is installed on the support 101, and the graded soil covering component includes a third telescopic rod 6 fixedly installed on the support 101, a first soil covering plate 601 is fixedly installed on the third telescopic rod 6, a fourth screw rod 602 is fixedly installed on the first soil covering plate 601, a second internally threaded rod 603 is rotatably installed on the support 101, the second internally threaded rod 603 is threadedly connected to the fourth screw rod 602, a connecting plate 604 is fixedly installed on the first soil covering plate 601, a fertilizer delivery pipe 401 is fixedly installed on the connecting plate 604, a lifting rod 605 is slidably installed on the connecting plate 604, a second soil covering plate 606 is fixedly installed on the lifting rod 605, an overflow hole 607 is opened on the second soil covering plate 606, a fifth screw rod 608 is fixedly installed on the second soil covering plate 606, and a third internally threaded rod 609 threadedly connected to the fifth screw rod 608 is rotatably installed on the connecting plate 604. Since the fertilizer cannot come into direct contact with the seeds, it prevents seed burn and the fertilizer is combined with the soil around the seeds to enhance the fertilization effect.

[0049] The height of the first covering plate 601 is higher than that of the second covering plate 606. The first covering plate 601 will contact the soil on both sides of the groove and push the soil above into the groove after the seeds are buried. At this time, the fertilizer pipe 401 that is subsequently moved above the seeds will discharge the fertilizer onto the soil above the seeds, and then the remaining soil will be pushed into the groove through the second covering plate 606 to bury the groove after fertilization, so that the fertilizer and soil are mixed and direct contact between the fertilizer and the seeds can be prevented, thereby effectively improving the fertilization effect.

[0050] By rotating the second internal threaded rod 603, the first covering plate 601 can be driven to move up and down, thereby driving the second covering plate 606 to move up and down. By adjusting the height of the first covering plate 601, the depth of the first trench covering can be controlled, and the gap between the second covering plate 606 and the ground can be controlled. Since the excavated soil will become fluffy, it is necessary to maintain a certain gap between the second covering plate 606 and the ground. When too much soil is accumulated on the second covering plate 606, the soil inside the second covering plate 606 will flow out through the overflow hole 607 and accumulate on the trench.

[0051] By rotating the third internal threaded rod 609, the second covering plate 606 can be driven to move up and down, so as to control the height of the second covering plate 606 and further adjust the effect after the second covering.

[0052] Furthermore, a vertical rod 610 is fixedly installed on the first soil cover plate 601, and a joint 611 is fixedly installed on both the fourth screw rod 602 and the vertical rod 610, and a third connecting rod 612 is rotatably installed at both ends of the joint 611, and two third connecting rods 612 located on the same side are rotatably connected through an adjustment block 613, and two-way screw rods 614 are threadedly connected on the two adjustment blocks 613. By rotating the two-way screw rod 614, the adjustment blocks 613 can be driven to move closer to or farther from each other, so that the distance between the two joints 611 can be controlled by rotating the third connecting rod 612, and the height of the first soil cover plate 601 can be further adjusted.

[0053] Among them, the first gear 7 is fixedly installed on the first internal thread rod 502, and the second gear 701 is fixedly installed on the second internal thread rod 603, and the first gear 7 and the second gear 701 are meshed with each other. Since the deeper the groove is excavated by the slotting block 501, the higher the soil accumulated on both sides of the groove will be. Therefore, when the slotting block 501 descends, the first soil cover plate 601 should rise accordingly. When the first internal thread rod 502 rotates, the second internal thread rod 603 can rotate in the opposite direction through the meshing of the first gear 7 and the second gear 701, so that the slotting block 501 can automatically raise the height of the first soil cover plate 601 when it descends, which can effectively save the operation time and is simple and quick to operate.

[0054] The working principle of this embodiment is: by making the slotting block 501 contact with the ground, when the device moves with the tractor, the slotting block 501 can open a groove on the ground. At this time, the original soil in the groove will be distributed on both sides of the groove. By rotating the first internal threaded rod 502, the slotting block 501 can be driven to rise and fall, and then the depth of the groove opened by the slotting block 501 can be adjusted to adapt to the depth of the groove required for sowing different seeds, and the seeds will enter the inside of the groove.

[0055] The height of the first covering plate 601 is higher than that of the second covering plate 606. The first covering plate 601 will contact the soil on both sides of the groove and push the soil above into the groove after the seeds are buried. At this time, the fertilizer pipe 401 that is subsequently moved above the seeds will discharge the fertilizer onto the soil above the seeds, and then the remaining soil will be pushed into the groove through the second covering plate 606 to bury the groove after fertilization, so that the fertilizer and soil are mixed and direct contact between the fertilizer and the seeds can be prevented, thereby effectively improving the fertilization effect.

[0056] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
