Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically a quantitative fertilization device for agricultural planting. Background Technology

[0002] Fertilization refers to agricultural techniques that involve applying fertilizer to the soil or spraying it on plants to provide the nutrients needed by the plants and to maintain and improve soil fertility. The amount of fertilizer applied is very important for agricultural planting. Applying too much fertilizer can easily lead to seedling burn, while applying too little fertilizer can easily lead to insufficient nutrition for crops.

[0003] A quantitative fertilization vehicle for planting winter peaches, with application number 202420443601.9, includes a base plate on which a fertilization frame is fixedly installed. This vehicle allows for single-stage fertilization by pulling a pull plate to one side, causing a shielding plate to no longer block the bottom of a conical cylinder, allowing fertilizer to fall onto the ground. When quantitative fertilization is needed, a rotating motor is activated, driving a threaded shaft to rotate. This causes a moving plate to move within a limiting groove, allowing adjustment of the distance between the moving plate and the shielding plate. This adjusts the area of ​​the conical cylinder blocked by the shielding plate during a single fertilization, controlling the weight of fertilizer falling during each application. This achieves quantitative fertilization of the winter peaches, avoiding the problems of existing fertilization vehicles that cannot quantitatively fertilize, resulting in uneven fertilization, fertilizer waste, and impaired fertilizer absorption by the winter peaches, leading to low fertilization efficiency.

[0004] This technical solution limits the amount of fertilizer applied by adjusting the size of the discharge port. However, solid fertilizer is usually in granular form. When the solid fertilizer is discharged by gravity for fertilization, the fertilizer rubs against each other, affecting the amount of fertilizer discharged. This can result in different amounts of fertilizer being discharged each time, which can easily lead to insufficient fertilizer application and crop nutrient deficiency. In addition, the bottom discharge structure is not convenient for fertilizing tall crops and can easily crush the crops. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a quantitative fertilization device for agricultural planting, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quantitative fertilization device for agricultural planting, comprising a base, guide rods fixed on both sides of the top of the base, and a storage box connected to the outside of the guide rods; springs connected to both sides of the bottom and top of the storage box; a screen installed above the inside of the storage box; a first electric cylinder, a metering cylinder, and a second electric cylinder respectively installed at the bottom of the base; a push plate connected to the output end of the first electric cylinder; a baffle connected to the output end of the second electric cylinder; a lead screw penetrating the outer surface of the push plate; a sealing plate sleeved on the outside of the lead screw; scales fixed on both sides of the sealing plate; guide frames fixed on both sides of the metering cylinder; and a pointer provided on one side of the guide frame.

[0007] By adopting the above technical solution, when setting the fertilizer application rate, the first electric cylinder pushes the push plate, causing the push plate, lead screw, sealing plate, and scale to extend outward simultaneously. Then, by rotating the lead screw in conjunction with the scale and guide frame, the sealing plate is displaced, thereby adjusting the distance between the sealing plate and the push plate to limit the fertilizer application rate. The distance between the sealing plate and the push plate can be viewed using a pointer and scale for precise adjustment. Before fertilization, the output end of the first electric cylinder drives the push plate to retract into the metering cylinder, causing the lead screw and sealing plate to retract. Simultaneously, the second electric cylinder activates, driving the baffle to move to the right, connecting the storage bin to the metering cylinder. At this time, the fertilizer in the storage bin falls into the metering cylinder, and is then released by the push plate. The gap between the sealing plate and the fertilizer plate limits the amount of fertilizer entering. When the device moves to the side of the next crop, the second electric cylinder drives the baffle to move to the left, disconnecting the connection between the storage box and the metering cylinder. Then, the output end of the first electric cylinder drives the push plate, the lead screw and the sealing plate to move to the left, thereby pushing the fertilizer in the metering cylinder to the periphery of the crop. The bumps generated by the device during its movement, combined with the spring and the guide rod, cause the storage box to vibrate up and down continuously. This serves two purposes: first, it can screen out clumps of fertilizer with the screen, preventing large pieces of fertilizer from being discharged; second, it can vibrate the waste inside the storage box, preventing the fertilizer from rubbing against each other and causing blockage between the storage box and the metering cylinder, thus accelerating the speed at which fertilizer enters the metering cylinder.

[0008] Furthermore, the storage bin is slidably connected to the guide rod, and the lower part of the storage bin is sloped.

[0009] By adopting the above technical solution, the bumps generated by the device during its movement, combined with the springs and guide rods, cause the storage bin to vibrate up and down continuously. This serves two purposes: firstly, it can screen out clumps of fertilizer with the help of the screen, preventing large pieces of fertilizer from being discharged for fertilization; secondly, it can vibrate the waste material inside the storage bin, preventing the fertilizer from rubbing against each other and causing blockages between the storage bin and the metering cylinder, thus accelerating the speed at which fertilizer enters the metering cylinder.

[0010] Furthermore, the top of the baffle is sloping, and the baffle is slidably connected to the storage bin and the metering cylinder respectively.

[0011] By adopting the above technical solution, after the second electric cylinder is turned off, the drive baffle moves to the left to disconnect the connection between the storage box and the metering cylinder. At the same time, the slope at the top of the baffle shovels the excess fertilizer back into the storage box.

[0012] Furthermore, the push plate is slidably connected to the metering cylinder, and the sealing plate abuts against the metering cylinder.

[0013] By adopting the above technical solution, the output end of the first electric cylinder drives the push plate to retract into the metering cylinder, thereby causing the lead screw and sealing plate to retract. At this time, the sealing plate abuts against and seals the left side of the metering cylinder.

[0014] Furthermore, the sealing plate is threadedly connected to the lead screw, and the lead screw is rotatably connected to the push plate, while the scale is slidably connected to the guide frame.

[0015] By adopting the above technical solution, the staff rotates the screw, which, in conjunction with the scale and the guide frame, causes the sealing plate to shift, thereby adjusting the distance between the sealing plate and the push plate to limit the amount of fertilizer applied. At the same time, the distance between the sealing plate and the push plate can be viewed by the pointer and the scale for precise adjustment.

[0016] Furthermore, four rollers are connected to each side of the bottom of the base, and the four rollers are distributed in a rectangular array.

[0017] By adopting the above technical solution, workers can move the device by towing with a vehicle or by other means, and the rollers facilitate the movement of the device.

[0018] Furthermore, the top of the storage box is connected to a box cover, and bolts penetrate all four sides of the box cover, with a small cover penetrating the top of the box cover.

[0019] By adopting the above technical solution, the staff removes the small cover and pours the fertilizer into the box cover. The box cover prevents the fertilizer from being discharged from both sides of the screen and wasting it. After the fertilizer is added, the staff puts the small cover back and closes it. After the fertilization work is completed, the staff removes the bolts to stop the box cover from being locked. Then the staff can remove the box cover to take out the large pieces of fertilizer that have clumped on the drying net for processing. After processing, the staff puts the box cover back and locks it by screwing in the bolts.

[0020] Furthermore, the box cover is detachably connected to the storage box via bolts.

[0021] By adopting the above technical solution, after the fertilization work is completed, the staff removes the bolts to stop the box lid from being locked. Then the staff can remove the box lid to take out the large pieces of fertilizer that have clumped on the drying net for processing. After processing, the staff put the box lid back and lock it by screwing in the bolts.

[0022] Furthermore, the small cover is detachably connected to the box cover via threads.

[0023] By adopting the above technical solution, the staff removes the small cover and pours the fertilizer into the box lid. After the fertilizer is added, the staff puts the small cover back on and closes it.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, through the setting of a measuring cylinder, push plate, lead screw, sealing plate, guide frame, scale, and pointer, allows for the setting of fertilizer application amount. When setting the fertilizer application amount, the first electric cylinder pushes the push plate, causing the push plate, lead screw, sealing plate, and scale to extend outward simultaneously. Then, by rotating the lead screw in conjunction with the guide frame and the scale to prevent rotation, the sealing plate is displaced, thereby adjusting the distance between the sealing plate and the push plate to limit the fertilizer application amount. At the same time, the distance between the sealing plate and the push plate can be viewed through the pointer and scale for precise adjustment. This improves the accuracy of quantitative fertilizer application, thereby significantly reducing the occurrence of over-fertilization or under-fertilization.

[0026] 2. The metering cylinder, baffle, push plate, and sealing plate of this utility model are configured such that before fertilization, the output end of the first electric cylinder drives the push plate to retract into the metering cylinder, thereby causing the lead screw and sealing plate to retract. At the same time, the second electric cylinder opens and drives the baffle to move to the right, connecting the storage box with the metering cylinder. At this time, the fertilizer in the storage box falls into the metering cylinder. The amount of fertilizer entering is limited by the gap between the push plate and the sealing plate. When the device moves to the side of the next crop, the second electric cylinder drives the baffle to move to the left, disconnecting the connection between the storage box and the metering cylinder. Then, the output end of the first electric cylinder drives the push plate, lead screw, and sealing plate to move to the left, thereby pushing the fertilizer in the metering cylinder to the periphery of the crop. Lateral fertilization effectively avoids the phenomenon of the device crushing the crop.

[0027] 3. This utility model, through the arrangement of guide rods, springs, and screens, causes the storage bin to vibrate continuously up and down during its movement, in conjunction with the springs and guide rods. This serves two purposes: firstly, the screens can separate clumps of fertilizer, preventing large pieces from being discharged for fertilization; secondly, the vibration of waste material inside the storage bin prevents friction and blockage between the storage bin and the metering cylinder, thus accelerating the flow of fertilizer into the metering cylinder; and thirdly, it prevents blockages and avoids the entry of clumps of fertilizer.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure. Example

[0036] A quantitative fertilization device for agricultural planting, such as Figures 1-5 As shown, the device includes a base 1, with guide rods 7 fixed on both sides of the top of the base 1. The storage box 3 is slidably connected to the guide rods 7. The lower part of the storage box 3 is sloping. The storage box 3 is connected to the outside of the guide rods 7. Springs 8 are connected to both sides of the bottom and the top of the storage box 3. A screen 19 is installed on the upper part of the storage box 3. The bumps generated by the device during movement, together with the springs 8 and the guide rods 7, cause the storage box 3 to vibrate up and down continuously. Together with the screen 19, it can screen out the clumps of fertilizer.

[0037] The base 1 is equipped with a first electric cylinder 9, a metering cylinder 10, and a second electric cylinder 11. The metering cylinder 10 and the first electric cylinder 9 are both tilted. The output end of the second electric cylinder 11 is connected to a baffle 12. The top of the baffle 12 is sloping. The baffle 12 is slidably connected to the storage box 3 and the metering cylinder 10. When the second electric cylinder 11 is turned on, it drives the baffle 12 to move to the right, so that the storage box 3 is connected to the metering cylinder 10. At this time, the fertilizer in the storage box 3 falls into the metering cylinder 10. When the second electric cylinder 11 is turned off, it drives the baffle 12 to move to the left, disconnecting the connection between the storage box 3 and the metering cylinder 10. At the same time, the slope at the top of the baffle 12 shovels the excess fertilizer back into the storage box.

[0038] The output end of the first electric cylinder 9 is connected to a push plate 13, which is slidably connected to the metering cylinder 10. The output end of the first electric cylinder 9 drives the push plate 13, the lead screw 14, and the sealing plate 15 to move to the left, thereby pushing the fertilizer in the metering cylinder 10 to the periphery of the crop. The lead screw 14 passes through the outer surface of the push plate 13 and is rotatably connected to the push plate 13. The sealing plate 15 is sleeved on the outside of the lead screw 14 and is threadedly connected to the lead screw 14. The sealing plate 15 abuts against the metering cylinder 10, and both sides of the sealing plate 15 are fixed with... The scale 17 and the measuring cylinder 10 are both fixed with guide frames 16. The scale 17 and the guide frame 16 are slidably connected. A pointer 18 is set on one side of the guide frame 16. When the operator rotates the screw 14, the guide frame 16 and the scale 17 and the guide frame 16 guide and stop the rotation, causing the sealing plate 15 to move, thereby adjusting the distance between the sealing plate 15 and the push plate 13 to limit the amount of fertilizer applied. At the same time, the distance between the sealing plate 15 and the push plate 13 can be viewed by the pointer 18 and the scale 17 for precise adjustment.

[0039] See Figure 1 and Figure 2 In the above embodiment, four rollers 2 are connected to the bottom sides of the base 1 respectively. The four rollers 2 are distributed in a rectangular array. The rollers 2 are arranged to facilitate the movement of the device in the planting area. Example

[0040] Based on the above embodiment one, the following settings are now adopted to facilitate fertilizer screening.

[0041] See Figure 1 and Figure 2 In the above embodiment, the top of the storage box 3 is connected to a box cover 4, which prevents fertilizer from being discharged from both sides of the screen 19 and wasting it; bolts 6 are inserted around the box cover 4, and the box cover 4 is detached and connected to the storage box 3 by the bolts 6. After the fertilization work is completed, the staff removes the bolts 6 to stop the box cover 4 from being restricted. Then the staff can remove the box cover 4 to take out the large pieces of fertilizer that have clumped on the drying net for processing. After processing, the staff puts the box cover 4 back and restricts it by screwing in the bolts 6; a small cover 5 is inserted through the top of the box cover 4, and the small cover 5 is detached and connected to the box cover 4 by the thread. The staff removes the small cover 5 and pours the fertilizer into the box cover 4. The fertilizer is filtered through the screen 19 to prevent the large pieces of fertilizer that have clumped on from falling into the storage box 3.

[0042] The implementation principle of this utility model is as follows: First, the operator turns on the first electric cylinder 9. After the first electric cylinder 9 starts, its output end drives the push plate 13 to move to the left, causing the push plate 13, lead screw 14, sealing plate 15, and scale 17 to extend outward simultaneously. Then, the operator rotates the lead screw 14, which, in conjunction with the scale 17 and the guide frame 16, causes the sealing plate 15 to move, thereby adjusting the distance between the sealing plate 15 and the push plate 13 to limit the amount of fertilizer applied. At the same time, the distance between the sealing plate 15 and the push plate 13 can be viewed through the pointer 18 in conjunction with the scale 17 for precise adjustment. After adjusting the amount of fertilizer, The worker shuts off the first electric cylinder 9, causing the output end of the first electric cylinder 9 to drive the push plate 13 to retract into the metering cylinder 10, thereby causing the lead screw 14 and the sealing plate 15 to retract. At this time, the sealing plate 15 abuts against the left side of the metering cylinder 10 to seal it, preventing subsequent fertilizer from being shaken out. At this time, the worker removes the small cover 5 and pours the fertilizer into the box cover 4. The fertilizer is filtered through the screen 19 to prevent large pieces of fertilizer from falling into the storage box 3. At the same time, the box cover 4 prevents fertilizer from being discharged from both sides of the screen 19, causing waste. Small pieces of fertilizer pass through the screen 19 and fall into the storage box 3. After the feeding is completed, the worker puts the small cover 5 back on and closes it.

[0043] Afterwards, the staff can move the device by towing or other means. At the same time, the staff will activate the second electric cylinder 11, which will drive the baffle 12 to move to the right, so that the storage box 3 is connected to the metering cylinder 10. At this time, the fertilizer in the storage box 3 falls into the metering cylinder 10. The amount of fertilizer entering is limited by the gap between the push plate 13 and the sealing plate 15. The bumps generated by the device during movement, together with the spring 8 and the guide rod 7, make the storage box 3 vibrate up and down continuously. First, it can screen the clumps of fertilizer with the screen 19 to avoid large pieces of fertilizer being discharged for fertilization. Second, it can vibrate the waste inside the storage box 3 to avoid the phenomenon of fertilizer rubbing against each other and causing blockage between the storage box 3 and the metering cylinder 10, thus speeding up the speed at which fertilizer enters the metering cylinder 10.

[0044] When the device moves to the side of the next crop, the operator closes the second electric cylinder 11 and opens the first electric cylinder 9. After the second electric cylinder 11 is closed, the baffle 12 moves to the left to disconnect the connection between the storage box 3 and the metering cylinder 10. At the same time, the slope at the top of the baffle 12 shovels the excess fertilizer back into the storage box. Then, the output end of the first electric cylinder 9 drives the push plate 13, the lead screw 14 and the sealing plate 15 to move to the left, thereby pushing the fertilizer in the metering cylinder 10 to the vicinity of the crop. Then, the cycle of closing the first electric cylinder 9, opening the first electric cylinder 9, moving the device, closing the second electric cylinder 11 and opening the first electric cylinder 9 is repeated to perform the fertilization operation, so that all crops can be quantitatively fertilized.

[0045] After the fertilization work is completed, the staff removes bolt 6 to stop the box cover 4 from being locked. Then the staff can remove the box cover 4 to take out the large pieces of fertilizer that have clumped on the drying net for processing. After processing, the staff put the box cover 4 back and lock it by screwing in bolt 6.
