The first lower cylinder piece and the second lower cylinder piece are slidably connected through the first sliding component, and the first lower cylinder piece and the second lower cylinder piece are respectively slidably connected with the bottom of the inner wall of the upper cylinder through the second sliding component and the third sliding component. A fixed rod is fixedly connected to the center of the inner top wall of the upper cylinder, and a fertilizer blocking component is arranged at the bottom of the fixed rod. Semi-circular soil pressing covers are fixedly connected to the bottoms of the first lower cylinder piece and the second lower cylinder piece, and the top of the upper cylinder is communicated with a fertilizer storage and replenishment component through a hose.

[0027] The upper parts of the first lower cylinder piece and the second lower cylinder piece are respectively a 3 / 5 cylindrical piece and a semi-cylindrical piece. The diameter and height of the first lower cylinder piece are smaller than those of the second lower cylinder piece and are embedded in the second lower cylinder piece to form a complete cylinder. The lower parts of the first lower cylinder piece and the second lower cylinder piece are both frustum cylinders with a larger top surface circle area and a smaller bottom surface circle area.

[0028] The first sliding component includes a first slider and a first chute. The first slider is fixedly connected to the outer side wall of the first lower cylinder piece at the overlapping part with the second lower cylinder piece, and the first chute is located on the inner side wall of the second lower cylinder piece corresponding to the first slider.

[0029] The second sliding component includes a second slider and a second sliding groove. The second slider is fixedly connected to the top of the outer side wall of the first lower cylinder piece at the junction with the upper cylinder. The third sliding component includes a third slider and a third sliding groove. The third slider is fixedly connected to the top of the outer side wall of the second lower cylinder piece at the junction with the upper cylinder. The second sliding groove and the third sliding groove are respectively embedded in both sides of the inner wall of the upper cylinder corresponding to the second slider and the third slider. The second sliding groove and the third sliding groove are two sliding grooves that slide from top to bottom but in opposite sliding directions.

[0030] The fertilizer storage component includes an upper housing and a lower housing. The upper housing and the lower housing are detachably connected, and a connection groove is provided at the connection between the upper housing and the lower housing.

[0036] The above fertilizing device has the following beneficial effects:

[0037] 1. The overall effect of the device is to form a depression when descending and fertilize when ascending. Fertilizing when ascending can reduce the problem that fertilizer cannot fall out or the fertilizing position is relatively shallow because the soil is squeezed into the device when descending, and improve the fertilizing efficiency of side deep fertilization.

[0038] 2. Forming a depression when descending can reduce the problem that water and soil enter the device due to the extrusion generated when descending, and improve the service life of the device.

[0039] 3. The design of the sliding component utilizes the kinetic energy of the mechanical arm ascending and descending when the seedling claws of the attached transplanter insert seedlings. It does not require an external energy supply device, is convenient for disassembly and installation, and improves the side deep fertilization efficiency of the device.

[0040] Referring to Figures 1-4 , the present invention provides a device for synchronous side deep fertilization during rice machine transplanting, including:

[0041] The first discharge pipe 1 is inclined. The bottom end of the first discharge pipe 1 is slidably connected with a second discharge pipe 2 along the axis of the first discharge pipe 1. The bottom end of the second discharge pipe 2 is rotatably connected with a third discharge pipe 3 coaxially. A fertilizer conveying assembly for conveying fertilizer into the second discharge pipe 2 is arranged in the first discharge pipe 1. A pulling and releasing assembly is arranged between the first discharge pipe 1 and the second discharge pipe 2. The pulling and releasing assembly is used to pull the second discharge pipe 2 in the direction of the first discharge pipe 1 by a certain distance and then release it. A spring 16 is abutted between the second discharge pipe 2 and the first discharge pipe 1. A rotation driving member is arranged between the third discharge pipe 3 and the second discharge pipe 2.

[0042] The feeding assembly includes a fertilizer tank 23, and the fertilizer tank 23 is communicated with the fertilizer conveying assembly.

[0043] The main function of the pulling and releasing assembly is to pull the second discharge pipe 2 in the direction of the first discharge pipe 1 by a certain distance and then release it. The main function of the spring 16 is to quickly push the second discharge pipe 2 in the opposite direction and reset it after the pulling and releasing assembly releases the second discharge pipe 2, so that the second discharge pipe 2 vibrates, forcing the adhered silt to fall off and ensuring normal discharge. The main function of the rotation driving member is to drive the third discharge pipe 3 to rotate and shake off the silt at the pipe orifice repeatedly to avoid blocking the pipe orifice. The main function of the fertilizer conveying assembly is to introduce the fertilizer from the fertilizer tank 23 into the first discharge pipe 1. The fertilizer passes through the first discharge pipe 1, the second discharge pipe 2 and the third discharge pipe 3 and finally drops from the bottom pipe orifice of the third discharge pipe 3 into the soil. Overall, by setting the first discharge pipe, the second discharge pipe and the third discharge pipe, the present invention uses the pulling and releasing assembly to drive the second discharge pipe to eject and vibrate, avoiding blockage inside the pipeline due to fertilizer or silt, and uses the rotation driving member to drive the third discharge pipe to rotate, avoiding silt adhesion at the orifice of the third discharge pipe, ensuring the smooth dropping of the fertilizer, and thus achieving the purpose of automatic side deep fertilization of rice and avoiding blockage of the fertilizer at the pipe orifice during the fertilization process, improving the uniformity and stability of the fertilization process.

[0044] In a further optimized solution, the fertilizer conveying assembly includes a conveying auger 4 rotatably connected in the first discharge pipe 1. The top of the first discharge pipe 1 is fixedly connected with a first motor 5, and the first motor 5 is in transmission connection with the conveying auger 4.

[0045] As Figure 2 shown, the first motor 5 is used to drive the conveying auger 4 to rotate, so that the conveying auger 4 conveys the fertilizer from the fertilizer tank 23 into the first discharge pipe 1. The fertilizer passes through the first discharge pipe 1, the second discharge pipe 2 and drops from the bottom pipe orifice of the third discharge pipe 3 into the soil.

[0046] The amount of fertilizer output can be controlled by controlling the rotation speed of the first motor 5.

[0047] For a further optimized solution, an annular chute 101 is provided at the inner bottom of the first discharge pipe 1. A connecting ring 201 is fixedly connected coaxially to the top of the second discharge pipe 2. The connecting ring 201 is slidably connected in the annular chute 101. A spring 16 is sleeved on the connecting ring 201, and the two ends of the spring 16 are respectively abutted against the bottom of the first discharge pipe 1 and the top of the second discharge pipe 2.

[0048] As Figure 2 shown, a limiting boss (not shown in the figure) is provided between the connecting ring 201 and the annular chute 101, and the limiting boss can prevent the connecting ring 201 from sliding out of the annular chute 101.

[0049] For a further optimized solution, the pulling and releasing assembly includes a first gear box 11 fixedly connected to the side wall of the first discharge pipe 1. A semi-gear 14 is rotatably connected in the first gear box 11. One end of a rack 15 is fixedly connected to the side wall of the second discharge pipe 2 along the axis of the first discharge pipe 1. The other end of the rack 15 penetrates upward through the first gear box 11 and is adapted to the semi-gear 14. A driving member for driving the semi-gear 14 to rotate is provided in the first gear box 11.

[0050] For a further optimized solution, the driving member includes a worm gear 13 rotatably connected in the first gear box 11. The worm gear 13 is fixedly connected coaxially to the semi-gear 14. A worm 12 is rotatably connected in the first gear box 11. The worm 12 is meshed with the worm gear 13. A second motor 9 is also fixedly connected to the first gear box 11. The second motor 9 is drivingly connected to the worm 12.

[0051] As Figure 2 and Figure 3 shown, during the rice transplanting and fertilizing process, the second motor 9 is started. The second motor 9 drives the worm 12 to rotate. The worm 12 drives the worm gear 13 to rotate clockwise. When the worm gear 13 rotates, it drives the semi-gear 14 to rotate clockwise. When the semi-gear 14 meshes with the rack 15, the semi-gear 14 pulls the rack 15 upward, causing the second discharge pipe 2 to move towards the first discharge pipe 1 and compress the spring 16.

[0052] When the semi-gear 14 rotates a certain angle and separates from the rack 15, the second discharge pipe 2 quickly moves downward and resets under the elastic force of the spring 16. The limiting boss is used to quickly stop the sliding of the second discharge pipe 2. The inertia is used to make the silt on the second discharge pipe 2 and the third discharge pipe 3 fall off, and at the same time, it is avoided that the fertilizer in the second discharge pipe 2 and the third discharge pipe 3 is blocked due to caking.

[0053] When the semi-gear 14 rotates to mesh with the rack 15 again, the above actions are repeated to ensure the smooth falling of the fertilizer.

[0054] According to a further optimized solution, a rotation groove 202 is provided at the inner bottom of the second discharge pipe 2 , and a connecting boss 301 is coaxially fixedly connected to the top of the third discharge pipe 3 , and the third discharge pipe 3 is rotatably connected in the rotation groove 202 via the connecting boss 301 .

[0055] A further optimized solution is that the rotating drive member includes a second gear box 22 fixedly connected to the bottom of the side wall of the second discharge pipe 2, and a connecting rod 19 is rotatably connected to the second discharge pipe 2 in the second gear box 22, and the connecting rod 19 is coaxially fixedly connected to the third bevel gear 20 at one end close to the second discharge pipe 2, and the connecting boss 301 is coaxially fixedly connected to the end away from the third discharge pipe 3, and the ring gear 21 is meshed with the third bevel gear 20, and the connecting rod 19 and the second motor 9 are connected through the second drive member.

[0056] A further optimized solution is that the second driving member includes a telescopic transmission rod 10, one end of the telescopic transmission rod 10 is coaxially fixedly connected to the worm gear 12, the other end of the telescopic transmission rod 10 is coaxially fixedly connected to the first bevel gear 17, and one end of the connecting rod 19 away from the third bevel gear 20 is coaxially fixedly connected to the second bevel gear 18, and the second bevel gear 18 is meshed with the first bevel gear 17.

[0057] like Figures 2-4 As shown, the telescopic transmission rod 10 is composed of a transmission rod and a transmission sleeve, and the transmission rod and the transmission sleeve are connected by a spline, which not only ensures that the telescopic transmission rod 10 can realize the transmission power, but also has a telescopic function to ensure that the second discharge pipe 2 moves smoothly in the axial direction.

[0058] When the second motor 9 rotates, it drives the telescopic transmission rod 10 to rotate, drives the first bevel gear 17 to rotate, the first bevel gear 17 drives the connecting rod 19 to rotate through the second bevel gear 18, and the connecting rod 19 drives the third bevel gear 20 to rotate the gear ring 21, thereby driving the connecting boss 301 to rotate in the rotating groove 202, thereby achieving the purpose of rotating the third discharge pipe 3 along the axis of the second discharge pipe 2. When the third discharge pipe 3 rotates, the sludge adhering to the pipe opening of the third discharge pipe 3 can be thrown out under the action of centrifugal force to prevent the sludge from blocking the pipe opening.

[0059] According to a further optimization scheme, the top of the side wall of the first discharge pipe 1 is connected with a feed pipe 6 , and the feed pipe 6 is connected with the bottom of the fertilizer box 23 through a connecting hose 24 .

[0060] Further optimization scheme, such as Figure 1As shown in the figure, the bottom of the fertilizer tank 23 is connected to a blanking chute 25. The bottom of the blanking chute 25 is set as an inclined plane. The top opening of the connecting hose 24 is connected to the lower end of the bottom of the blanking chute 25. The fertilizer in the fertilizer tank 23 enters the first discharge pipe 1 through the connecting hose 24 and the blanking pipe 6, and is conveyed to the second discharge pipe 2 under the action of the conveying auger 4.

[0061] In a further optimized solution, a support rod 8 is fixedly connected to the side wall of the first discharge pipe 1. A shovel 7 is fixedly connected to the support rod 8. The shovel 7 is used to open a groove on the soil surface. The shovel 7 is located in front of the third discharge pipe 3.

[0062] As Figure 1 and Figure 2 shown in the figure, along the traveling direction of the rice transplanter, the top of the first discharge pipe 1 is tilted forward, so that the pipe orifice of the third discharge pipe 3 faces backward, avoiding the entry of silt. At the same time, a shovel 7 is provided at the bottom of the first discharge pipe 1, and it is ensured that the shovel 7 is in front of the pipe orifice of the third discharge pipe 3. When the transplanter is working, the shovel 7 first digs a groove in the soil, so that the pipe orifice of the third discharge pipe 3 moves in the groove at the opening, and the fertilizer is accurately spread into the groove, realizing side deep fertilization.

[0063] The working process of this embodiment is as follows: Before working, an appropriate number of synchronous fertilization devices are installed on the transplanter according to the number of rows of rice transplanting of the transplanter.

[0064] During operation, start the first motor 5 to drive the conveying auger 4 to rotate, so that the fertilizer in the fertilizer tank 23 drops from the pipe orifice of the third discharge pipe 3 into the groove dug by the shovel 7. After working for a period of time, the second motor 9 can be started to drive the semi-gear 14 to pull the rack 15. After releasing the rack 15, the second discharge pipe 2 quickly bounces to clear the silt and the fertilizer caking in the pipe. At the same time, the second motor 9 drives the third discharge pipe 3 to rotate around its own axis, and uses centrifugal force to shake off the silt at the pipe orifice, avoiding the blockage of the pipe orifice by silt and ensuring that the fertilizer can always fall smoothly.
