Description

Technical Field

[0001] The invention belongs to the technical field of fertilization devices, and in particular relates to an integrated sowing and fertilization device for cultivating a new corn variety Linyu No. 6. Background Art

[0002] Corn is one of the most important food crops in the world and is widely used in many fields such as food, feed and industrial raw materials. There are many varieties of corn, such as "Linyu No. 6", which has outstanding comprehensive characteristics, compact plant shape, significant increase in yield compared with the control, and generally high and stable yield (more than 800 kg per mu). It is suitable for planting in most suitable areas in my country, but it needs to be used with caution in some areas in the south where rust is prevalent.

[0003] In the process of corn cultivation, the sowing and fertilization of corn seeds are often completed simultaneously through the integrated sowing and fertilization device, which not only saves the time and labor of the two operations, reduces the number of mechanical operations, improves the operation efficiency, but also reduces the number of mechanical equipment, saves fuel, reduces labor, and thus reduces production costs. However, the existing integrated sowing and fertilization devices often have the following technical problems when used:

[0004] When sowing, the sowing depth cannot be adjusted according to soil conditions and climate change, so the appropriate sowing depth cannot be maintained. There are cases where the sowing is too deep or too shallow, which further leads to problems such as uneven emergence, poor root development, increased pests and diseases, and uneven water absorption, thus affecting the overall growth and development of corn and ultimately reducing yields;

[0005] In addition, the difference in sowing depth will affect the suitability of the amount of fertilizer applied and have a series of adverse effects on crop growth: when sowing is shallow, if too much fertilizer is applied, it will lead to salt accumulation, increasing the risk of crop "root burn", while causing great waste of fertilizer and increasing fertilization costs; when sowing is deep, the fertilizer is far away from the seeds. If the amount of fertilizer applied is too little, the corn seeds will not absorb the fertilizer as quickly in the initial growth stage as when sown shallowly, making the corn unable to obtain the required nutrients in the short term, resulting in slow growth.

[0006] Therefore, there is an urgent need for an integrated sowing and fertilization device that can adjust the sowing depth and synchronously adjust the amount of fertilizer according to the sowing depth to avoid excessive or insufficient fertilizer application. Summary of the invention

[0007] The purpose of the present invention is to address the problems raised in the above-mentioned background technology and to provide an integrated sowing and fertilization device for cultivating a new corn variety Linyu No. 6, which can adjust the sowing depth according to soil conditions and climate changes, maintain a suitable depth during sowing, and automatically adjust the amount of fertilizer according to the sowing depth.

[0021] Compared with the existing technology, the advantages of the integrated sowing and fertilization device for cultivating the new corn variety Linyu No. 6 are:

[0022] 1. The present invention sets a depth adjustment mechanism. During sowing, the height of the lifting plate is adjusted by the hydraulic cylinder, and then the height of the furrow opener is adjusted, and the depth of the soil pressed down by the furrow opener is adjusted to achieve the adjustment of the sowing depth. The sowing depth can be adjusted according to soil conditions and climate changes, and the appropriate depth can be maintained during sowing, thereby improving the overall development speed and yield of corn.

[0023] 2. The present invention provides a fertilizer amount adjustment mechanism and a transmission component. When the lifting plate moves downward to increase the sowing depth, the piston block and the guide triangle plate are driven to move downward, and the two clamping baffles are pushed away from each other through the guide roller. When the sowing is deeper, the two clamping baffles open the strip fertilizer holes to a greater extent, so that the fertilizer in the fertilizer box can be discharged through the strip fertilizer holes faster, and the fertilizer amount per unit time is increased. The fertilizer amount is automatically adjusted according to the sowing depth. When the sowing is shallow, the fertilizer amount is less, which reduces the risk of crop "root burn" and reduces the fertilization cost. When the fertilizer is deeper, the fertilizer amount is more, and the corn seeds can obtain the required nutrition in the initial growth stage, ensuring the normal growth of the corn seeds.

[0024] 3. The present invention sets an anti-blocking mechanism. During the process of sowing and fertilizing, the second motor drives the rotating rod to rotate, thereby rotating the lower pressure block, periodically pushing the transmission plate to move downward, so that the multiple movable sleeves can reciprocate vertically relative to the fixed sleeve, so that the fertilizer can vibrate when discharged, and the vibration is used to help the fertilizer particles pass smoothly, thereby reducing the blockage problem in the fertilizer transportation process, ensuring that the fertilizer can be applied smoothly, and improving the fertilization efficiency.

[0025] 4. The present invention provides a wetting mechanism. When fertilizing, when the pressing block rotates to abut against the transmission plate, it will first push the protrusion to slide inside the suction groove, and then push the transmission plate downward. When the pressing block rotates to no longer abut against the transmission plate, the protrusion will be reset under the elastic force of the third spring, so that the wetting water in the water storage chamber can be continuously pumped out to the soil surface after fertilization, which helps dissolve and evenly distribute the fertilizer, ensures that the corn can absorb it in time, and improves the fertilization effect.

[0033] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0034] Example: Refer to Figures 1 to 6 , a sowing and fertilization integrated device for cultivating a new corn variety Linyu No. 6, comprising:

[0035] A frame 1, a transmission wheel set 11 is rotatably connected to the front side of the frame 1, a driving wheel set 12 is rotatably connected to the rear side of the frame 1, a furrow opener 13 is provided on the front side of the frame 1, a placement groove 14 is provided at the bottom of the frame 1, and a fertilizer box 15 is provided in the placement groove 14;

[0036] Specifically, the transmission wheel set 11 and the driving wheel set 12 drive the frame 1 to move in a common rear-drive manner.

[0037] Specifically, the furrow opener 13 includes two support plates 131 fixedly connected to the lower end of the lifting plate 21, and a furrowing roller 132 is rotatably connected between the two support plates 131. A first motor 133 for driving the furrowing roller 132 is provided on the side wall of one of the support plates 131. When in use, the first motor 133 is turned on to drive the furrowing roller 132 to rotate and draw seed furrows in the soil to facilitate the subsequent placement of corn seeds in the soil. This is an existing mature technology, so it will not be elaborated on.

[0038] Specifically, a seeder (not shown in the figure) is also provided between the furrow opener 13 and the fertilizer box 15, which includes multiple seed bins and multiple sowing pipes connected to the seed bins, so that the seeder can achieve zoned sowing of seeds during sowing, which is suitable for intercropping of corn and other crops.

[0039] A depth adjustment mechanism 2 is used to adjust the height of the furrow opener 13 to adjust the sowing depth. The depth adjustment mechanism 2 includes a lifting plate 21 slidably connected to the outer wall of the frame 1 in the vertical direction. The furrow opener 13 is fixedly installed below the lifting plate 21. A hydraulic cylinder 22 for driving the lifting plate 21 is fixedly connected to the outer wall of the frame 1.

[0040] In view of the problem that the prior art cannot adjust the sowing depth according to soil conditions and climate changes, the present invention sets a depth adjustment mechanism 2. During sowing, the height of the lifting plate 21 is adjusted by the hydraulic cylinder 22, and then the height of the furrow opener 13 is adjusted. The depth to which the furrow opener 13 presses down on the soil is adjusted, thereby achieving adjustment of the sowing depth. The sowing depth can be adjusted according to soil conditions and climate changes, and an appropriate depth can be maintained during sowing, thereby improving the overall development speed and yield of corn.

[0041] The fertilizer amount adjustment mechanism 3 is used to adjust the fertilizer amount according to the sowing depth. The fertilizer amount adjustment mechanism 3 includes a plurality of strip fertilizer holes 31 opened on the bottom wall of the fertilizer box 15. The two side walls of the fertilizer box 15 are sealed and slidably connected with a snap-on baffle 32. Two symmetrically arranged control chambers 33 are opened inside the frame 1. The snap-on baffle 32 is slidably connected to the bottom wall of the control chamber 33 at the corresponding position, and a first spring 34 is provided between the snap-on baffle 32 and the inner wall of the control chamber 33. A hinge seat 35 is provided at the upper end of the snap-on baffle 32, and a guide roller 36 is hinged on the hinge seat 35. The inner wall of the control chamber 33 is slidably connected with a guide triangular plate 37 in the vertical direction. The guide roller 36 rolls in contact with the guide triangular plate 37. A transmission assembly 38 is provided between the guide triangular plate 37 and the lifting plate 21, which is used to drive the guide triangular plate 37 to change in height when the height of the lifting plate 21 changes.

[0042] Specifically, the elastic force of the first spring 34 can make the clamping baffles 32 approach each other after the guide triangle plate 37 moves upward, thereby ensuring the subsequent adjustment effect of the clamping baffle 32 on the fertilizer application amount.

[0043] Specifically, the arrangement of the snap-fit ​​baffle 32 can also play a role in the installation and disassembly of the fertilizer box 15. When the two snap-fit ​​baffles 32 move away from each other until they are completely removed from the fertilizer box 15, the fertilizer box 15 can be taken out from the placement slot 14, which is convenient for the staff to clean it. After cleaning, it is only necessary to put the fertilizer box 15 back to the initial position, and move the two snap-fit ​​baffles 32 close to each other and enter the fertilizer box 15 to achieve installation. The operation is convenient. At the same time, a fertilizer delivery pipe is provided at the upper end of the frame 1, which can be sealed and connected to the fertilizer box 15 when the fertilizer box 15 enters the placement slot 14 to ensure the delivery of fertilizer.

[0044] The transmission assembly 38 includes two hydraulic boxes 381 fixedly connected to the outer wall of the frame 1, each hydraulic box 381 is sealed and slidably connected with a piston plate 382, ​​each piston block 385 is fixedly connected to the lifting plate 21 with a connecting column 383, the upper end of each control cavity 33 is provided with a liquid storage tank 384, each liquid storage tank 384 is sealed and slidably connected with a piston block 385, each piston block 385 is fixedly connected to the guide triangle plate 37 at the corresponding position with a connecting rod 386, and the lower side wall of each hydraulic box 381 and the inside of the frame 1 are provided with an infusion channel 387, and the interior of the hydraulic box 381 is connected to the interior of one of the liquid storage tanks 384 through the infusion channel 387.

[0045] In view of the problem in the prior art that the difference in sowing depth will affect the suitability of the amount of fertilizer applied and have a series of adverse effects on the growth of crops, the present invention sets a fertilizer amount adjustment mechanism 3 and a transmission assembly 38. When the lifting plate 21 moves downward to increase the sowing depth, the piston plate 382 is driven to move downward in the hydraulic box 381, and more hydraulic oil in the hydraulic box 381 is squeezed into the liquid storage tank 384, thereby driving the piston block 385 and the guide triangular plate 37 to move downward. When the two guide triangular plates 37 move downward, the two clamping baffles 32 are pushed away from each other through the guide roller 36, and they move away from each other. The degree of increase increases with the increase of the downward movement distance of the two guide triangle plates 37. Therefore, when the sowing is deeper, the two clamping baffles 32 open the strip fertilization holes 31 to a greater extent, so that the fertilizer in the fertilizer box 15 can be discharged through the strip fertilization holes 31 faster, and the amount of fertilizer per unit time is increased, so that the amount of fertilizer is automatically adjusted according to the sowing depth. When the sowing is shallow, the amount of fertilizer is less, reducing the risk of crop "root burn" and reducing the cost of fertilization. When the fertilizer is deeper, the amount of fertilizer is more, and the corn seeds can get the required nutrition in the initial growth stage, ensuring the normal growth of the corn seeds.

[0046] An anti-blocking mechanism 4 is provided below the fertilizing box 15 to prevent fertilizer from being blocked during fertilizing. The anti-blocking mechanism 4 includes a plurality of trapezoidal material transfer frames 41 fixedly connected to the lower end of the fertilizing box 15. The plurality of trapezoidal material transfer frames 41 are connected to the interior of the fertilizing box 15 through the strip fertilizing holes 31 at corresponding positions. The lower end of each trapezoidal material transfer frame 41 is fixedly connected to a fixed sleeve 42. The inner wall of each fixed sleeve 42 is sealed and slidably connected to a movable sleeve 43. A transmission plate 44 is fixedly connected between the plurality of movable sleeves 43. A second spring 45 is provided at the bottom end of the transmission plate 44 and the plurality of fixed sleeves 42. A second motor 46 is fixedly connected to the inner wall of the placement slot 14. A rotating rod 47 is fixedly connected to the output end of the second motor 46. A lower pressing block 48 is fixedly connected to the rotating rod 47. The lower pressing block 48 periodically contacts the upper end of the transmission plate 44.

[0047] Specifically, the provision of a plurality of strip-shaped fertilizer holes 31 allows the fertilizer to be applied more evenly, thereby avoiding the problem of excessive concentration of fertilizer when applied from one point, improving the uniformity of fertilization and ensuring the normal growth of corn seeds.

[0048] Specifically, the plurality of trapezoidal material transfer frames 41 provide a certain buffer space for the fertilizer when passing through the strip-shaped fertilizing holes 31, thereby preventing fertilizer blockage.

[0049] Specifically, a U-shaped plate 5 is fixedly connected to the inner wall of the placement groove 14, and the rotating rod 47 penetrates and is rotatably connected to the U-shaped plate 5. The arrangement of the U-shaped plate 5 can make the rotating rod 47 more stable when rotating.

[0050] In order to avoid clogging during the application of fertilizer, the present invention sets an anti-clogging mechanism 4. During the sowing and fertilizing process, the second motor 46 drives the rotating rod 47 to rotate, thereby rotating the lower pressing block 48, periodically pushing the transmission plate 44 to move downward, and making the transmission plate 44 reciprocate vertically under the elastic force of the second spring 45, so that the multiple movable sleeves 43 can reciprocate vertically relative to the fixed sleeve 42, so that the fertilizer can vibrate when it is discharged through the fixed sleeve 42 and the movable sleeve 43, and the vibration is used to help the fertilizer particles pass smoothly, thereby reducing the blockage problem in the fertilizer transportation process, ensuring that the fertilizer can be applied smoothly, and improving the fertilization efficiency.

[0051] The frame 1 is also provided with a wetting mechanism 6 controlled by the pressing block 48, which is used to help dissolve the fertilizer after fertilization. The wetting mechanism 6 includes a water storage chamber 61 opened inside the frame 1, and a water guide groove 62 connected to the bottom of the frame 1 is opened on the side of the water storage chamber 61 close to the placement groove 14. A rotating drum 63 is sealed and rotatably connected to the inner wall of the placement groove 14. A suction groove 64 is opened inside the pressing block 48, and a protrusion 65 is sealed and slidably connected to the inner wall of the suction groove 64. A third spring 66 is provided between the protrusion 65 and the inner wall of the suction groove 64. The part of the protrusion 65 extending outside the pressing block 48 is periodically in contact with the upper end of the transmission plate 44. The end of the rotating drum 63 close to the pressing block 48 is sealed and rotatably connected to the pressing block 48, and the rotating drum 63 connects the suction groove 64 and the water guide groove 62.

[0052] Specifically, one-way valves are provided at positions above and below the rotating drum 63 in the water guide groove 62. Through the setting of the one-way valves, when the protrusion 65 is away from the suction groove 64, the wetting water in the water storage chamber 61 can only be pumped into the position between the rotating drum 63 and the two one-way valves, and when the protrusion 65 is close to the suction groove 64, the wetting water between the rotating drum 63 and the two one-way valves can only be pumped out to the bottom of the frame 1, thereby avoiding the backflow of the wetting water and ensuring the dissolution of the fertilizer.

[0053] Specifically, the frame 1 is fixedly connected with a water guide plate 7 at a position directly below the discharge outlet of the water guide trough 62. The two sides of the water guide plate 7 are arranged to be inclined downward, and a plurality of drainage holes are opened on the water guide plate 7. Through the arrangement of the water guide plate 7, the wetting water will not be concentrated in one place when discharged, but will slide to both sides along the water guide plate 7, and be evenly discharged to different seeds through a plurality of drainage holes, so as to fully dissolve the fertilizer at the seeds at each position.

[0054] Specifically, the rotating drum 63 and the rotating rod 47 are coaxially arranged, so that when the rotating rod 47 drives the lower pressing block 48 to rotate, it will not cause torsion to the rotating drum 63, thereby avoiding motion interference.

[0055] Specifically, a flushing groove is provided between the water storage chamber 61 and the outside, and an opening and closing valve is provided in the flushing groove for replenishing the wetting water in the water storage chamber 61 after it is used up.

[0056] In order to improve the absorption efficiency of corn for fertilizer, the present invention is provided with a wetting mechanism 6. When fertilizing, when the pressing block 48 rotates to abut against the transmission plate 44, it will first push the protrusion 65 to slide inside the suction groove 64, and then push the transmission plate 44 downward. When the pressing block 48 rotates to no longer abut against the transmission plate 44, the protrusion 65 will be reset under the elastic force of the third spring 66, so that the protrusion 65 can reciprocate in the suction groove 64 to continuously pump the wetting water in the water storage chamber 61 into the water guide groove 62 and the rotating drum 63, and continuously pump the wetting water in the rotating drum 63 and the water guide groove 62 to the soil surface after fertilization, so as to help the fertilizer dissolve and evenly distribute, ensure that the corn can absorb it in time, and improve the fertilization effect.

[0057] The present invention can be explained by the following operation mode:

[0058] When in use, the height of the lifting plate 21 is first adjusted by the hydraulic cylinder 22, and then the height of the furrow opener 13 is adjusted, and the depth of the furrow opener 13 pressing down the soil is adjusted to achieve the adjustment of the sowing depth;

[0059] When the lifting plate 21 moves downward to increase the sowing depth, the piston plate 382 squeezes more hydraulic oil in the hydraulic box 381 into the liquid storage tank 384, driving the piston block 385 and the guide triangular plate 37 to move downward, and the two clamping baffles 32 are pushed away from each other through the guide roller 36, and the degree of their mutual distance increases with the increase of the downward movement distance of the two guide triangular plates 37. Therefore, when the sowing is deeper, the degree to which the two clamping baffles 32 open the strip fertilization holes 31 is greater, so that the fertilizer in the fertilizer box 15 can be discharged faster through the strip fertilization holes 31, thereby increasing the amount of fertilizer per unit time, and automatically adjusting the amount of fertilizer according to the sowing depth;

[0060] The first motor 133 is turned on to drive the furrowing roller 132 to rotate, and a seed furrow is drawn in the soil. The sowing pipe sows the seeds in the seed furrow. The fertilizer box 15 transports the fertilizer to the soil surface through the strip fertilizer hole 31, the trapezoidal material transfer frame 41, the fixed sleeve 42 and the movable sleeve 43, so as to realize the sowing and fertilization work.

[0061] The second motor 46 is turned on to drive the rotating rod 47 to rotate, thereby rotating the lower pressing block 48, periodically pushing the transmission plate 44 to move downward, and causing the transmission plate 44 to make a reciprocating vertical displacement under the elastic force of the second spring 45, so that the plurality of movable sleeves 43 can make a reciprocating vertical displacement relative to the fixed sleeve 42, so that the fertilizer can vibrate when being discharged through the fixed sleeve 42 and the movable sleeve 43, and the vibration is used to help the fertilizer particles pass smoothly;

[0062] When the pressing block 48 rotates, it first contacts the transmission plate 44, pushing the protrusion 65 to slide inside the suction groove 64, and then pushing the transmission plate 44 downward. When the pressing block 48 rotates until it no longer contacts the transmission plate 44, the protrusion 65 will be reset under the elastic force of the third spring 66, so that the protrusion 65 can reciprocate in the suction groove 64 to continuously pump the moistening water in the water storage chamber 61 to the soil surface after fertilization, thereby helping the fertilizer to dissolve and be evenly distributed.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
