[0038] In this way, the fertilizer from the outlet of hopper 3 into fertilizer disc is continuously transported to discharge port 7 by the rotation of fertilizer disc 4 driven by drive mechanism, and the outlet size of hopper 3 can also be adjusted according to actual needs by adjusting mechanism 5, which can completely replace manual fertilization, effectively reduce labor intensity, improve work efficiency, and has high intelligence and strong practicability.

[0039] Specifically as follows:

[0040] As shown in Figure 2 Hopper 3, first support barrel 8, second support barrel 9 and third support barrel 10 are arranged in barrel 2 from top to bottom, wherein the openings of first support barrel 8 and second support barrel 9 are oppositely arranged, and they are both arranged close to the inner wall of barrel 2, and the cavity surrounded thereby is provided with drive mechanism 6, fertilizer disc 4 is arranged in the inside of third support barrel 10, hopper 3 is in the form of a funnel structure as a whole, and is provided with a vibrator thereon, the outlet thereof is deviated to one side, and extends to the top of fertilizer disc 4 through first support barrel 8 and second support barrel 9, and the vibrator is used to vibrate hopper to help the fertilizer inside to flow out of hopper better.

[0041] In order to ensure that the fertilizer can enter the hopper 3, the inner wall of the barrel 2 is provided with a concave step at the corresponding position, so that the hopper 3 can be closely arranged with the barrel 2, and the connection part of the two can be smoothly transitioned, avoiding hanging and sticking of the fertilizer. At the same time, a plurality of mounting grooves are uniformly and spacedly arranged along the side wall of the barrel 2, which extend from the hopper 3 to the third supporting barrel 10, and mounting holes are arranged at the corresponding positions of the hopper 3, the first supporting barrel 8, the second supporting barrel 9 and the third supporting barrel 10, so that the hopper 3 to the third supporting barrel 10 can be fixed on the barrel 2 by bolts and the like.

[0042] The driving mechanism 6 includes a motor and a reducer connected therewith, which are fixed on the first supporting barrel 8 and the second supporting barrel 9 through L-shaped folding plates, and the reducer transmits the rotation of the motor to the fertilizer spreading disc 4 through two meshing gears. A rotating shaft is arranged at the center position of the fertilizer spreading disc 4, the free end of the rotating shaft is connected with the center shaft of one of the gears through the second supporting barrel 9 to realize transmission, and a bearing is arranged at the connecting position of the rotating shaft and the second supporting barrel 9 to ensure smooth rotation.

[0043] The fertilizer spreading disc 4 is a key part of the fertilizer spreading vehicle, which is used to uniformly throw out the fertilizer. It is driven by a motor such as a direct current motor in cooperation with a micro gearbox, and different rotating speeds are adjusted under different conditions to adapt to the working requirements of the fertilizer spreading vehicle.

[0044] The motor is the power source of the fertilizer spreading disc 4, which is controlled by an embedded microprocessor and can meet the needs of different fertilizer spreading ranges. In order to improve the working efficiency of the fertilizer spreading vehicle, the motor can be selected as a GRS-775 motor with moderate power.

[0045] As shown in Figure 4 The fertilizer spreading disc 4 is arranged in the interior of the third supporting barrel 10, and they are nested together. Of course, it can also be directly matched with the side wall of the barrel 2, in which case the third supporting barrel 10 is not needed. The fertilizer spreading disc 4 includes a rotating disc, a plurality of paddles are uniformly and spacedly arranged on the rotating disc, the paddles are distributed in a radial manner with the center of the rotating disc as the center, the outlet of the hopper 3 extends to the area above the two adjacent paddles of the fertilizer spreading disc 4, and then openings are arranged at the corresponding positions of the first supporting barrel 8 and the second supporting barrel 9 to facilitate the passing of the hopper 3. The end face of the outlet of the hopper 3 can be flush with the opening end face of the second supporting barrel 10, so that the fertilizer can flow out to the fertilizer spreading disc 4.

[0046] The fertilizer spreading disc 4 can be made of polyethylene plastic. There are six paddles on the disc, which can be used to stir the fertilizer to be spread out. There is a shaft key groove in the middle of the disc, which is connected with the rotating shaft. There are annular reinforcing ribs below the disc, which can strengthen the bearing capacity of the disc. The disc body is slightly concave and has a circular arc shape with a curvature of about 0.13×10 -3 mm, and the upper and lower errors do not exceed 0.1×10 -5mm, to adjust the trajectory of the fertilizer throwing, to ensure the uniformity of the fertilizer throwing.

[0047] As Figure 3 shown, in order to adjust the size of the outlet of the hopper 3, we add an adjusting mechanism 5 at the outlet position of the hopper 3, which includes a pull plate 501, one end of which extends to the outlet of the hopper through the wall of the barrel 2, and the other end is in the form of a rack structure, which is engaged with a transmission gear 502, the center shaft of which is connected with the output shaft of a steering engine 503, which is used to drive the engagement transmission of the transmission gear 502 and the other end of the pull plate 501, to drive the one end of the pull plate 501 to approach or move away from the outlet, to adjust the overlapping area of the one end of the pull plate 501 with the outlet of the hopper 3, thereby adjusting the size of the outlet of the hopper 3.

[0048] A support plate 504 is arranged below the one end of the pull plate 501, which is connected with the second support barrel 9, and an opening is arranged at the position opposite to the outlet of the hopper 3, and a plurality of convex points are arranged on the opposite surfaces of the support plate 504 and the pull plate 501, which are arranged in staggered engagement, as Figure 5 shown, so that the one end of the pull plate 501 can be supported, and at the same time, the staggered convex points can hinder the movement of the pull plate 501, to avoid the pull plate 501 moving too fast, and to help control the size adjustment of the outlet of the hopper 3.

[0049] A plurality of stop columns 505 are arranged on the end surface of the one end of the pull plate 501, which are exposed inside the outlet of the hopper 3, and cooperate with the side wall of the hopper 3 at the outlet, to limit the movement position of the pull plate 501, to avoid the pull plate 501 moving too much or too little.

[0050] In order to improve the fertilization efficiency, the discharge port 7 can be provided with two, which are located on both sides of the forward direction of the moving trolley 1, and are connected with the vehicle shell of the moving trolley 1, and an extension plate 11 is connected on each of them, which extends from the discharge port 7 to the ground. Since the fertilizer disc 4 rotates under the drive of the driving mechanism, as long as the discharge port 7 is opened on the side wall of the barrel 2, the fertilizer can flow out. Considering that crops are usually located on both sides of the moving trolley 1, two discharge ports can be provided, and as the moving trolley 1 travels, fertilization can be carried out on both sides of the crops at the same time, and the working efficiency is higher.

[0051] The vehicle body of the moving trolley 1 is made of high-strength steel, and track wheels are installed on both sides to ensure smooth running of the fertilizer spreading vehicle in the field.

[0052] The vehicle shell is provided with a pull ring, a hinge door and other components, facilitating carrying, fixing, disassembly and maintenance, etc. An opening is arranged on the top of the vehicle shell to communicate with the material cylinder, facilitating the feeding of fertilizer into the hopper.

[0053] The vehicle shell is also provided with wifi and radio signal transmitting and receiving devices, and the user can change the instructions at any time by using a remote control device. An adjustable searchlight 102 is arranged in front of the vehicle shell to ensure the smooth operation of the fertilizer spreader in different light environments.

[0054] The vehicle shell is also provided with wifi and radio signal transmitting and receiving devices, and the user can change the instructions at any time by using a remote control device. An adjustable searchlight 102 is arranged in front of the vehicle shell to ensure the smooth operation of the fertilizer spreader in different light environments.

[0055] When the solid fertilizer spreader is used for fertilization, first, the driving route of the mobile trolley is planned, then the fertilization amount is calculated according to the actual needs, the rotation speed of the fertilizer disc is controlled by the driving mechanism, the vibration frequency of the hopper is adjusted by the vibrator, and the outlet size of the hopper is adjusted by the adjusting mechanism when necessary, so as to ensure that the fertilizer flowing out of the discharge port meets the fertilization amount requirement. At this time, the above three parameters can be adjusted appropriately according to the actual fertilizer flowing out, and finally, the mobile trolley is driven to walk along the driving route.

[0056] Although the specific embodiments of the present application are described above, those skilled in the art should understand that these are only examples, and various changes or modifications can be made to these embodiments without departing from the principles and essence of the present application, therefore, the protection scope of the present application is defined by the appended claims.
