Technical Field

[0001] This utility model relates to the field of rice planting technology, specifically a mechanical transmission rice fertilization device. Background Technology

[0002] Rice is an annual aquatic herbaceous plant of the Poaceae family (perennial rice varieties also exist). Its culms are erect, 0.5-1.5 meters tall, depending on the variety. When planting rice, it is necessary to fertilize the rice using a fertilization device.

[0003] For example, a high-efficiency fertilization device for rice cultivation, authorized by announcement number CN220935637U, includes an installation frame, on which a storage box is provided, and at the bottom of the storage box are multiple discharge hoppers, each of which is equipped with a discharge pipe; although the above document can simultaneously adjust the discharge rate of fertilizer in multiple discharge pipes, replacing the existing quantitative structure, the adjustment method is simple, it will not cause fertilizer blockage, and it is highly practical;

[0004] However, in the existing fertilization device, the fertilizer inside the hopper needs to enter the fertilizer discharge device at the bottom at the same time, and then the fertilizer is discharged through the discharge pipe. When the fertilizer enters the fertilizer discharge device, it is easy to get clogged at the top of the fertilizer discharge device due to its poor flowability. This causes the fertilizer discharge devices to be unable to feed at the same time, resulting in different amounts of fertilizer being discharged from the multiple discharge pipes, thereby reducing the fertilization effect of the existing fertilization device. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mechanically driven rice fertilization device, comprising a feed hopper, a cover mounted on top of the feed hopper, a fertilizer discharge device fixedly connected to the bottom of the feed hopper, a fertilizer delivery pipe connecting the feed hopper and the fertilizer discharge device, a discharge pipe connecting the bottom of the fertilizer discharge device, and a dredging mechanism provided on the outside of the feed hopper, the dredging mechanism comprising: a vertical column disposed on the outer wall of the feed hopper; a first bevel gear mounted on the top of the vertical column; a first crossbar mounted on the top of the vertical column via the first bevel gear assembly; and a cam fixedly connected to the first bevel gear assembly. The crossbar has an outer wall; a crossbar is positioned below the cam; a spring has its two ends respectively mounted on the outer wall of the crossbar and the outer wall of the box cover; a vertical rod is fixedly connected to the side of the crossbar away from the cam, passes through the box cover, and is movably connected to the box cover; a stirring unit is positioned outside the material box; wherein, the first bevel gear set, driven by the vertical rod, causes the first crossbar to rotate, thereby causing the cam to move the crossbar, which in turn causes the spring to deform, and finally causes the vertical rod to move up and down, thus stirring the fertilizer inside the fertilizer dispenser through the stirring unit.

[0007] Preferably, the stirring unit includes: a second bevel gear set installed at the bottom of the vertical column; a second crossbar installed at the bottom of the vertical column via the second bevel gear set, and its outer wall rotatably connected to the inner wall of the fertilizer dispenser via a bearing; and stirring blades fixedly connected to the outer wall of the second crossbar; wherein, driven by the second crossbar, the stirring blades cause the second bevel gear set to rotate the vertical column, and the stirring blades stir the fertilizer inside the fertilizer dispenser.

[0008] Preferably, the outer wall of the cam is fitted with a roller, which is mounted above the crossbar.

[0009] Preferably, each of the four corners of the bottom of the material box is equipped with a traveling wheel, and the number of traveling wheels is four. One of the traveling wheels is fixedly connected to a pulley on its outer wall, and the number of pulleys is two.

[0013] Preferably, a connector is fixedly connected to the front of the material box.

[0014] Beneficial effects

[0015] This utility model provides a mechanically driven rice fertilization device. It has the following advantages: This mechanically driven rice fertilization device, through the cooperation of the vertical column, cover, support column, first bevel gear set, first crossbar, outer shell, cam, crossbar, roller, spring, and upright, achieves synchronous feeding of multiple fertilizer applicators. This solves the problem in existing fertilization devices where, due to the poor flowability of fertilizer, it easily clogs the top of the fertilizer applicator, causing asynchronous feeding of multiple applicators and resulting in different amounts of fertilizer being discharged from multiple discharge pipes, thus reducing the fertilization effect of existing fertilization devices.

[0016] The cooperation between the second bevel gear set, the second crossbar, and the stirring blade enables the fertilizer inside the fertilizer dispenser to be stirred, making the fertilizer more evenly mixed. This solves the problem of uneven mixing of fertilizer that may occur when fertilizer enters the fertilizer dispenser, since there is no stirring structure inside the fertilizer dispenser to stir the fertilizer.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] When using existing fertilization devices, the poor flowability of fertilizer makes it easy to get clogged at the top of the fertilizer discharger. This causes the fertilizer to not be fed into the multiple dischargers at the same time, resulting in different amounts of fertilizer being discharged from the multiple discharge pipes, thus reducing the fertilization effect of the existing fertilization devices.

[0025] In view of this, the present invention provides a mechanical transmission rice fertilization device. Through the cooperation between the vertical column, cover, support column, first bevel gear set, first crossbar, outer shell, cam, crossbar, roller, spring and upright, the internal feeding of multiple fertilizer dischargers is synchronized. This solves the problem that in the use of existing fertilization devices, due to the poor flowability of fertilizer, it is easy to block the top of the fertilizer discharger, resulting in the inability of multiple fertilizer dischargers to feed synchronously, causing different amounts of fertilizer to be discharged from multiple discharge pipes, thereby reducing the fertilization effect of existing fertilization devices.

[0026] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.

[0027] Example 1, by Figures 1 to 5As can be seen, the mechanical transmission rice fertilization device in this case includes a feed box 1, with a cover 2 installed on top of the feed box 1. The feed box 1 and the cover 2 can be connected by bolts. The worker pours fertilizer into the feed box 1 through the feed inlet at the top of the cover 2. A fertilizer discharge device 4 is fixedly connected to the bottom of the feed box 1. The fertilizer then enters the fertilizer discharge device 4 through a fertilizer conveying pipe 3. The fertilizer in the feed box 1 enters the fertilizer conveying pipe 3 through the fertilizer conveying pipe 3. The bottom of the fertilizer discharge device 4 is connected to a discharge pipe 5, which is equipped with an on / off valve. The worker opens the discharge pipe 5 through the on / off valve, and the fertilizer inside the fertilizer discharge device 4 falls into the water through the discharge pipe 5. In paddy fields, fertilizer can be precisely applied 4.5 cm to the side of the seedlings at a depth of 5 cm, accurately achieving the purpose of lateral deep fertilization. It can automatically adjust the fertilization speed and real-time fertilizer application based on the rice transplanter's operating speed and the total fertilizer application per acre, ensuring uniform and accurate fertilization. This reduces fertilizer usage and labor costs, improves fertilizer utilization, reduces costs and increases efficiency, and promotes environmental protection. The feed hopper 1 is externally equipped with a clearing mechanism 6, which includes: a vertical column 61, located on the outer wall of the feed hopper 1; and a first bevel gear set 62, which includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly connected to the top of the vertical column 61. A second bevel gear is connected to the side meshing connection. The second bevel gear is fixedly connected to the end of the first crossbar 63 and installed on the top of the vertical column 61. During fertilization, the vertical column 61 drives the first bevel gear set 62 to rotate. The first crossbar 63 is installed on the top of the vertical column 61 through the first bevel gear set 62. The first bevel gear drives the first crossbar 63 to rotate. Cams 64 are fixedly connected to the outer wall of the first crossbar 63. The first crossbar 63 drives the cams 64 to rotate. There are six cams 64. A crossbar 65 is set below the cams 64. The cams 64 drive the crossbar 65 to move. Springs 66 are installed at both ends on the outer wall of the crossbar 65 and the outer wall of the box cover 2, respectively. The column 65 causes the spring 66 to deform. The upright rod 67 is fixedly connected to the side of the horizontal column 65 away from the cam 64, and passes through the box cover 2 and is movably connected to the box cover 2. The horizontal column 65 drives the upright rod 67 to move. The upright rod 67 moves in the box cover 2 and moves up and down to clear the fertilizer inside the fertilizer conveying pipe 3. The stirring unit 68 is set outside the material box 1. The first bevel gear set 62 is driven by the vertical column 61 to make the first horizontal rod 63 rotate, thereby causing the cam 64 to drive the horizontal column 65 to move, which in turn causes the spring 66 to deform. Finally, it drives the upright rod 67 to move up and down, and the stirring unit 68 stirs the fertilizer inside the fertilizer discharger 4.

[0028] In the specific implementation process, it is worth noting that the feed bin 1 and the cover 2 can be connected by bolts. Workers pour fertilizer into the feed bin 1 through the inlet at the top of the cover 2. The fertilizer in the feed bin 1 enters the fertilizer delivery pipe 3, and then enters the fertilizer discharge device 4 through the fertilizer delivery pipe 3. An on / off valve is installed on the discharge pipe 5. Workers open the discharge pipe 5 using the on / off valve, and the fertilizer inside the fertilizer discharge device 4 falls into the paddy field through the discharge pipe 5. This allows for precise application of fertilizer to the side of the seedlings at a depth of 5 cm, accurately achieving the purpose of side-deep fertilization. The system can automatically adjust the fertilization speed and real-time fertilizer application based on the rice transplanter's operating speed and the total fertilizer application per acre, ensuring uniform and accurate fertilization. This reduces fertilizer usage and labor costs, and improves fertilizer utilization. To reduce costs and increase efficiency, and promote environmental protection, during fertilization, the vertical column 61 drives the first bevel gear set 62 to rotate. The first bevel gear set 62 includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly connected to the top of the vertical column 61, and the second bevel gear is meshed with one side of the first bevel gear. The second bevel gear is fixedly connected to the end of the first horizontal bar 63. The first bevel gear drives the first horizontal bar 63 to rotate, and the first horizontal bar 63 drives the cams 64 to rotate. There are six cams 64. The cams 64 drive the horizontal column 65 to move, and the horizontal column 65 causes the spring 66 to deform. The horizontal column 65 drives the vertical bar 67 to move, and the vertical bar 67 moves in the box cover 2. The vertical bar 67 moves up and down to clear the fertilizer inside the fertilizer conveying pipe 3, realizing synchronous feeding inside multiple fertilizer dischargers 4.

[0029] Furthermore, the stirring unit 68 includes: a second bevel gear set 681, which includes a third bevel gear and a fourth bevel gear. The third bevel gear is fixedly connected to the end of the second crossbar 682, and the fourth bevel gear is meshed with one side of the third bevel gear. The fourth bevel gear is fixedly connected to the top of the vertical column 61 and installed at the bottom of the vertical column 61. The second bevel gear set 681 drives the vertical column 61 to rotate. The second crossbar 682 is installed at the bottom of the vertical column 61 via the second bevel gear set 681. 2 drives the second bevel gear set 681 to rotate, and its outer wall is rotatably connected to the inner wall of the fertilizer dispenser 4 through a bearing. The stirring blade 683 is fixedly connected to the outer wall of the second crossbar 682. The second crossbar 682 drives the stirring blade 683 to rotate. The stirring blade 683 stirs the fertilizer inside the fertilizer dispenser 4, making it more evenly mixed. Under the drive of the second crossbar 682, the stirring blade 683 causes the second bevel gear set 681 to drive the vertical column 61 to rotate, and the stirring blade 683 stirs the fertilizer inside the fertilizer dispenser 4.

[0030] In the specific implementation process, it is worth noting that during fertilization, the second crossbar 682 rotates, which drives the stirring blade 683 to rotate. The stirring blade 683 stirs the fertilizer inside the fertilizer dispenser 4, making it more evenly mixed. The second crossbar 682 drives the second bevel gear set 681 to rotate. The second bevel gear set 681 includes a third bevel gear and a fourth bevel gear. The third bevel gear is fixedly connected to the end of the second crossbar 682, and the fourth bevel gear is meshed with one side of the third bevel gear. The fourth bevel gear is fixedly connected to the top of the vertical column 61. The second bevel gear set 681 drives the vertical column 61 to rotate, thereby stirring the fertilizer inside the fertilizer dispenser 4 and making the fertilizer more evenly mixed.

[0031] Furthermore, a roller 651 is attached to the outer wall of the cam 64. When the upright 67 moves, the cam 64 drives the roller 651 to move. The roller 651 rotates on the surface of the cam 64. The roller 651 is installed above the crossbar 65. The roller 651 drives the crossbar 65 to move, and finally drives the upright 67 to move. This reduces the friction between the cam 64 and the crossbar 65 by using the roller 651.

[0032] In the specific implementation process, it is worth noting that when the upright 67 moves, the cam 64 drives the roller 651 to move, the roller 651 rotates on the surface of the cam 64, the roller 651 drives the cross column 65 to move, and finally drives the upright 67 to move, thereby reducing the friction between the cam 64 and the cross column 65 through the roller 651.

[0033] Furthermore, four wheels 7 are installed at the four corners of the bottom of the material box 1. When the fertilizer applicator moves, the four wheels 7 at the bottom of the material box 1 rotate. A pulley 71 is fixedly connected to the outer wall of one wheel 7. The wheel 7 on the left rear side drives the lower pulley 71 to rotate. There are two pulleys 71. One pulley 71 is fixedly connected to the outer wall of the second crossbar 682. The outer walls of the two pulleys 71 are both attached to belts 72. The lower pulley 71 drives the belt 72 to rotate. The belt 72 drives the upper pulley 71 to rotate. The upper pulley 71 drives the second crossbar 682 to rotate, thereby driving the unblocking mechanism 6 and the mixing unit 68 to work.

[0034] In the specific implementation process, it is worth noting that when the fertilizer application device moves, the four walking wheels 7 at the bottom of the material box 1 rotate. The walking wheel 7 on the left rear side drives the lower pulley 71 to rotate, the lower pulley 71 drives the belt 72 to rotate, the belt 72 drives the upper pulley 71 to rotate, and the upper pulley 71 drives the second crossbar 682 to rotate, thereby driving the unblocking mechanism 6 and the mixing unit 68 to work.

[0035] Specifically, firstly, the staff pours fertilizer into the inside of the hopper 1 through the inlet at the top of the cover 2. The fertilizer in the hopper 1 enters the fertilizer conveying pipe 3, and then enters the fertilizer discharger 4 through the fertilizer conveying pipe 3. An on / off valve is installed on the discharge pipe 5. The staff opens the discharge pipe 5 through the on / off valve, and the fertilizer inside the fertilizer discharger 4 falls into the paddy field through the discharge pipe 5. Then, when the fertilization device moves, the four wheels 7 at the bottom of the hopper 1 rotate. The left rear wheel 7 drives the lower pulley 71 to rotate, the lower pulley 71 drives the belt 72 to rotate, the belt 72 drives the upper pulley 71 to rotate, and the upper pulley 71 drives the second crossbar 682 to rotate. The second crossbar 682 drives the stirring blade 683 to rotate, which stirs the fertilizer inside the fertilizer dispenser 4. The second crossbar 682 drives the second bevel gear set 681 to rotate, which in turn drives the vertical column 61 to rotate. The vertical column 61 drives the first bevel gear set 62 to rotate, which in turn drives the first crossbar 63 to rotate. The first crossbar 63 drives the cam 64 to rotate, and the roller 651 rotates on the surface of the cam 64. The roller 651 drives the horizontal column 65 to move, which causes the spring 66 to deform. The horizontal column 65 drives the vertical rod 67 to move, which moves within the cover 2 and moves up and down to clear the fertilizer inside the fertilizer delivery pipe 3.

[0036] Example 2, by Figure 1 , 2 As can be seen from points 4 and 5, a cover 611 is fixedly connected to the outer wall of the material box 1. The cover 611 can cover the first bevel gear set 62, the vertical column 61, and the second bevel gear set 681 to prevent workers from accidentally touching the rotating first bevel gear set 62, the vertical column 61, and the second bevel gear set 681.
