Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer spreaders, in particular to a light electric fertilizer spreader. Background Art

[0002] A fertilizer spreader is an agricultural machine used to spread various chemical fertilizers such as granular fertilizer, liquid fertilizer, manure, manure and compost on the field. This equipment is designed to improve the efficiency and accuracy of fertilization, reduce manual labor intensity, and promote crop growth and increase yields.

[0003] According to the Chinese patent with announcement number: CN220126059U, a fertilizer spreader includes a stepper motor, a turntable is fixedly installed on the output end of the stepper motor, a working box is fixedly installed on the top of the turntable, springs are fixedly installed on both sides of the inner cavity of the working box, a mixing box is fixedly installed on one end of the springs close to each other, a vibration motor is fixedly installed on the right end of the mixing box, stirring boxes are fixedly installed on both sides of the lower end of the inner cavity of the working box through brackets, and a driving motor is fixedly installed on the left end of the stirring box.

[0004] In the above scheme, the rotation of the stirring blade drives the multiple mixed raw materials to be mixed and stirred multiple times, and the mixed raw materials are discharged through the discharge pipe and the guide plate. The above scheme still has the following disadvantages: in the process of spreading fertilizer, the fertilizer can only be discharged through the guide plate, resulting in a small spreading range and low fertilization efficiency. Utility Model Content

[0005] The utility model aims to provide a light electric fertilizer spreader to solve the problem that in the process of spreading fertilizer, the fertilizer can only be discharged through the guide plate, resulting in a small spreading range and low fertilization efficiency.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a light electric fertilizer spreader, including a frame, a base is fixed to the inner top surface of the frame, a rear baffle is fixed to the top surface of the base, one side of the rear baffle is open, blades are rotatably arranged inside the rear baffle, a drive motor is fixed to the bottom surface of the base, and the output end of the drive motor passes through the base and the rear baffle and is connected to the blades.

[0007] Preferably, two free stop hinges are fixed to the opening of the rear baffle, and side baffles are fixed to the free stop hinges.

[0008] Preferably, a fertilizer box is fixed on the top surface of the frame, a fertilizer hole is opened on the top surface of the frame, a through hole is opened on the bottom surface of the fertilizer box, the fertilization hole corresponds to the through hole opened on the bottom surface of the fertilizer box, and a discharge valve is arranged inside the through hole opened on the bottom surface of the fertilizer box.

[0009] Preferably, a rod frame is fixed to the side of the frame, and wheels are connected to the bottom ends of both sides of the rod frame respectively. A hub motor is provided inside the wheel, and a walking wheel connecting shaft is connected to the hub motor inside the wheel.

[0010] Preferably, a differential is connected to the upper portion of the walking wheel link shaft, a mounting box is fixed to the bottom surface of the frame, a differential motor is fixed inside the mounting box, and an output end of the differential motor is connected to the differential.

[0011] Preferably, a support rod is fixed to the rear side of the frame, a connecting cover is fixed to the bottom end of the support rod, and a supporting wheel is rotatably provided inside the connecting cover.

[0012] Compared with the prior art, a light electric fertilizer spreader using the above technical solution has the following beneficial effects:

[0013] 1. During use, the staff puts the granular compound fertilizer into the fertilizer box. When fertilization is required, the staff starts the drive motor, and the output end of the drive motor rotates and drives the blades to rotate. At this time, the discharge valve is opened, and the granular compound fertilizer passes through the discharge valve and the fertilization hole and falls onto the blades. The blades rotate rapidly under the drive of the drive motor, and the granular compound fertilizer is thrown out under the action of the centrifugal force of the blades, thereby realizing the fertilization process. The drive motor drives the blades to rotate, and the centrifugal force is used to throw out the granular compound fertilizer, which can achieve fast and uniform fertilization and improve the fertilization efficiency. At the same time, the staff can adjust the rotation speed of the blades by controlling the drive motor, and then control the speed and range of fertilization, making the fertilization operation more flexible and precise. In addition, this device can adapt to different types of granular compound fertilizers, has good applicability, can be used in different farmlands and crops, and improves the adaptability of the overall device;

[0014] Before fertilizing, the staff can change the angle of the side baffle by stopping the hinge at will to ensure that the compound fertilizer is within the operating range of the fertilizer spreader. The fertilizer can be thrown out from the front to avoid being thrown out to the rear of the fertilizer spreader, thus improving the accuracy of the fertilization process;

[0015] 2. During use, the wheel hub motor inside the wheel can drive the wheel and the fertilizer spreader as a whole to move. The system has high transmission efficiency and does not require a reduction mechanism. It not only makes the entire wheel structure simpler and more compact, but also reduces the axial size, and further improves efficiency and responds faster. It is beneficial to the overall machine structure layout and fertilizer spreader design, and is also convenient for retrofit design. The differential is installed on the walking wheel link shaft. When the fertilizer spreader needs to turn, the differential is used to achieve different speeds of the wheels on the left and right sides to complete the turning action.

[0016] The differential is controlled by a differential motor;

[0017] 3. During use, the coordinated use of the support rod, the connecting cover and the support wheel makes the fertilizer spreader work more smoothly, avoiding the phenomenon that the fertilizer spreader may tip over when the fertilizer box is filled with compound fertilizer due to the excessive total weight, and improving the stability during the walking process. The backward and forward extension structure of the frame can lower the center of gravity of the whole machine and improve the stability of the fertilizer spreader. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] During use, the staff puts the granular compound fertilizer into the interior of the fertilizer box 8. When fertilization is required, the staff starts the drive motor 5. The output end of the drive motor 5 rotates and drives the blades 3 to rotate. At this time, the discharge valve is opened, and the granular compound fertilizer passes through the discharge valve and the fertilization hole 9 and falls onto the blades 3. The blades 3 rotate rapidly under the drive of the drive motor 5, and the granular compound fertilizer is thrown out under the action of the centrifugal force of the blades 3, thereby realizing the fertilization process. By driving the blades 3 to rotate by the drive motor 5 and using the centrifugal force to throw out the granular compound fertilizer, fast and uniform fertilization can be achieved, and the fertilization efficiency is improved. At the same time, the staff can adjust the rotation speed of the blades 3 by controlling the drive motor 5, and then control the speed and range of fertilization, making the fertilization operation more flexible and accurate. In addition, the device can adapt to different types of granular compound fertilizers, has good applicability, can be used in different farmlands and crops, and improves the adaptability of the overall device;

[0026] Before fertilizing, the staff can change the angle of the side baffle 7 by stopping the hinge 6 at will to ensure that the compound fertilizer is within the operating range of the fertilizer spreader, and can be thrown out from the front to avoid being thrown out to the rear of the fertilizer spreader, thereby improving the accuracy of the fertilization process.

[0027] like Figure 1-Figure 3 As shown, a rod frame 10 is fixed to the side of the frame 1, and wheels 12 are connected to the bottom ends of both sides of the rod frame 10 respectively. The wheel 12 has a hub motor inside. The hub motor inside the wheel 12 is connected to a travel wheel connecting shaft 11, and the upper part of the travel wheel connecting shaft 11 is connected to a differential 15. An installation box 13 is fixed to the bottom surface of the frame 1, and a differential motor 14 is fixed inside the installation box 13. The output end of the differential motor 14 is connected to the differential 15.

[0028] During use, the wheel 12 and the fertilizer spreader as a whole can be driven to move by the hub motor inside the wheel 12. The system has high transmission efficiency and does not require a reduction mechanism. Not only does it make the entire wheel 12 structure simpler and more compact, the axial size is also reduced, and the efficiency is further improved, and the response speed is also faster. It is beneficial to the overall structural layout and fertilizer spreader design, and is also convenient for retrofit design. The differential 15 is installed on the walking wheel link shaft 11. When the fertilizer spreader needs to turn, the wheels 12 on the left and right sides roll at different speeds through the differential 15, thereby completing the turning action. The differential 15 is controlled by the differential motor 14.
