Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a fertilizer box for a planting machine. Background Technology

[0002] With the popularization of agricultural machinery, many farmers have started using planting machines for cassava planting. Planting machines generally require tractor traction. The planting machine obtains power through the rolling of its wheels, which drives the blade box on the planting machine to rotate, cutting the cassava into small pieces and letting them fall into the furrows prepared by the planting machine. After passing through the soil covering device of the planting machine, the planting is completed, realizing automated planting. In the early stage of cassava planting, chemical fertilizers are also needed to improve the survival rate. However, the current chemical fertilizers are mainly scattered on the soil surface, which has limited help to cassava seed formation. Therefore, some people have thought of adding chemical fertilizers into the furrows when planting cassava. The existing fertilizer tanks in the fertilizer tanks fall into the furrows by gravity. However, some fertilizers are prone to clumping after getting damp, which can get stuck at the discharge port. Therefore, it is necessary to design a fertilizer tank for the planting machine. It obtains power through the wheels of the planting machine, which drives the mixing wheel at the bottom of the fertilizer tank to break up the fertilizer clumps and ensure the effective discharge of fertilizer. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a fertilizer bin for a planting machine. Powered by the planter's wheels, the fertilizer bin's lower stirring wheel breaks up fertilizer clumps, ensuring effective fertilizer discharge.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a fertilizer box for a planting machine, comprising: a fertilizer box body, a stirring wheel, a hopper, and a gearbox. The fertilizer box body and the gearbox are both mounted on the frame of the planting machine. The stirring wheel is mounted on the bottom of the fertilizer box body, and the output shaft of the gearbox passes through the fertilizer box body and is connected to the stirring wheel. The input shaft of the gearbox is connected to the blade box drive shaft on the planting machine via a chain and a sprocket. A discharge port is provided on one side of the fertilizer box body, and the hopper is located outside the discharge port. The lower part of the hopper extends into the ridging mechanism of the planting machine via a flexible hose.

[0006] Furthermore, the gearbox includes a housing, a first bevel gear, and a second bevel gear. The first bevel gear is mounted in the housing via an input shaft, and the second bevel gear is mounted in the housing via an output shaft. The first bevel gear and the second bevel gear mesh with each other, and the first bevel gear and the second bevel gear are fixedly connected to the input shaft and the output shaft, respectively. The output shaft is perpendicular to the input shaft.

[0007] Furthermore, the lower part of the fertilizer box body is truncated cone-shaped, and the blades of the stirring wheel are 3cm to 5cm away from the discharge port.

[0008] Furthermore, the lower part of the hopper is provided with two discharge pipes, which are respectively extended into the ridge-opening mechanism of the planting machine through hoses.

[0009] Furthermore, the fertilizer box body is provided with a cover plate on the upper part, the cover plate is connected to the fertilizer box body by a hinge, and the fertilizer box body is provided with a limiting block.

[0010] Furthermore, a baffle is provided on the outside of the discharge port, and the baffle is installed on both sides of the discharge port via sliding grooves.

[0011] Furthermore, a fixing plate is provided 15cm to 30cm above the baffle, and the fixing plate is fixedly connected to the fertilizer box body. The fixing plate is connected to the baffle by a cable.

[0012] The beneficial effects of this utility model are as follows: By connecting the gearbox to the drive shaft of the blade box on the planter, rotational power is obtained, which drives the stirring wheel to rotate at the bottom of the fertilizer box body, breaking up the damp and clump-forming fertilizer. The stirring of the stirring wheel can also prevent the fertilizer from getting stuck in the discharge port, ensuring the orderly discharge of the fertilizer. The discharged fertilizer is guided through the hose to the ridge-opening mechanism of the planter, and then falls into the furrow along with the cassava seeds, providing the necessary growth elements for the cassava during its growth and improving the germination rate of the cassava.

If the specific posture changes, the directional indicators will also change accordingly.

[0021] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0022] like Figures 1 to 5 As shown, an embodiment of this utility model provides a fertilizer box for a planting machine, including: a fertilizer box body 1, a stirring wheel 2, a hopper 3, and a gearbox 4. The fertilizer box body 1 and the gearbox 4 are both mounted on the frame of the planting machine. The stirring wheel 2 is mounted on the bottom of the fertilizer box body 1, and the output shaft 9 of the gearbox 4 passes through the fertilizer box body 1 and is connected to the stirring wheel 2. The input shaft 10 of the gearbox 4 is connected to the blade box drive shaft on the planting machine through a chain and a sprocket. A discharge port 5 is provided on one side of the fertilizer box body 1, and the hopper 3 is located outside the discharge port 5. The lower part of the hopper 3 extends into the ridging mechanism of the planting machine through a hose.

[0023] The planter moves under the traction of a tractor. The rotation of the wheels drives the blade box on the planter to rotate. The gearbox 4 of this device is connected to the tractor via a chain and sprockets. The output shaft 9 of the gearbox 4 drives the mixing wheel 2 to rotate within the fertilizer tank body 1. Clumps of fertilizer in the fertilizer tank body 1 are broken up by the mixing wheel 2, preventing clumps from blocking the discharge port 5. The rotation of the mixing wheel 2 also prevents fertilizer granules from getting stuck in the discharge port 5. Under gravity, the fertilizer granules are discharged from the discharge port 5 and fall into the hopper 3. After being discharged from the discharge pipe 11 of the hopper 3, they are guided by a hose to the ridging mechanism of the planter, where they fall into the furrows along with the cassava seed heads cut by the blade box. This provides the necessary growth elements for the cassava during its growth, improving its germination rate.

[0024] In a preferred embodiment, the gearbox 4 includes a housing 6, a first bevel gear 7, and a second bevel gear 8. The first bevel gear 7 is mounted in the housing 6 via an input shaft 10, and the second bevel gear 8 is mounted in the housing 6 via an output shaft 9. The first bevel gear 7 and the second bevel gear 8 mesh with each other and are fixedly connected to the input shaft 10 and the output shaft 9, respectively. The output shaft 9 is perpendicular to the input shaft 10. The input shaft 10 is linked to the blade box drive shaft on the planter via a chain and sprocket. After the input shaft 10 drives the first bevel gear 7, the second bevel gear 8 and the output shaft 9 rotate synchronously, realizing the reversal of power. This allows the stirring wheel 2 to rotate vertically in the fertilizer box body 1, which can better break up the clumps of fertilizer particles.

[0025] Specifically, the lower part of the fertilizer box body 1 is truncated cone-shaped, which allows the fertilizer to gradually concentrate. The blade of the stirring wheel 2 is 3cm to 5cm away from the discharge port 5. Through the stirring of the stirring wheel 2, the fertilizer particles can be prevented from getting stuck on the discharge port 5, and the surrounding fertilizer can be stirred, making it easier for the fertilizer in the fertilizer box body 1 to be discharged from the discharge port 5.

[0026] Preferably, the lower part of the hopper 3 is provided with two discharge pipes 11, which extend to the ridge-opening mechanism of the planter through hoses. The planter is provided with two sets of blade boxes. In order to match them, the lower part of the hopper 3 is provided with two discharge pipes 11 to divert the fertilizer, so that the fertilizer particles can enter the corresponding furrows.

[0027] In a preferred embodiment, a cover plate 12 is provided on the upper part of the fertilizer box body 1. The cover plate 12 is connected to the fertilizer box body 1 by a hinge. The cover plate 12 can prevent rainwater and other substances from entering the fertilizer box body 1, ensuring the dryness of the fertilizer. A limiting block 13 is provided on the fertilizer box body 1. When the cover plate 12 is opened, the limiting block 13 can hold the cover plate 12 in place, keeping the cover plate at a certain opening angle, which facilitates the pouring of fertilizer granules into the fertilizer box body 1.

[0028] In one specific embodiment, a baffle 14 is provided on the outside of the discharge port 5. The baffle 14 is installed on both sides of the discharge port 5 through a sliding groove. The opening of the discharge port 5 can be adjusted by the position of the baffle 14, thereby controlling the discharge speed of fertilizer and avoiding the fertilizer from being discharged too fast or too slow.

[0029] In a preferred embodiment, a fixing plate 15 is provided 15cm to 30cm above the baffle 14. The fixing plate 15 is fixedly connected to the fertilizer box body 1, and the fixing plate 15 is connected to the baffle 14 via a cable. The cable adopts the same principle as the cable used for bicycle brakes. By pulling the cable with a handle inside the tractor, the position of the baffle 14 on the chute can be controlled, thereby controlling the opening of the discharge port 5 and realizing the control of the fertilizer discharge speed.

[0030] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
