Description

Technical Field

[0001] This utility model relates to the field of fertilizer spreading vehicle technology, specifically to a fertilizer spreading and discharging mechanism for a fertilizer spreading vehicle. Background Technology

[0002] A fertilizer spreader is a device used in agricultural production to spray fertilizer onto fields.

[0003] The existing fertilizer spreading mechanism of fertilizer spreading trucks spreads fertilizer through spray nozzles set on the side of the fertilizer spreading truck. This not only results in a small spreading area but also uneven spraying and poor fertilization effect. Utility Model Content

[0004] The purpose of this utility model is to provide a fertilizer spreading mechanism for a fertilizer spreading vehicle, which solves the technical problems of small spreading area and uneven spraying in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fertilizer spreading mechanism for a fertilizer spreading vehicle, comprising a fertilizer tank, a water pump fixedly installed on the top of the fertilizer tank, a spherical shell connected to the water pump outlet, a rotating shaft rotatably disposed within the spherical shell, blades fixedly connected in a circular array on the rotating shaft, a disc fixedly connected to the top of the rotating shaft, a second fixing rod fixedly connected to the outer wall of the fertilizer tank, a second limiting sleeve fixedly connected to one end of the second fixing rod, a fertilizer spreading pipe rotatably disposed within the second limiting sleeve and communicating with the spherical shell, nozzles arrayed on the fertilizer spreading pipe, and nozzles arrayed on the fertilizer spreading pipe. A toothed ring is provided, and a first fixed rod is fixedly connected to the second fixed rod. A first limiting sleeve is fixedly connected to the upper end of the first fixed rod. An L-shaped rod is slidably arranged inside the first limiting sleeve. A toothed plate that meshes with the toothed ring is fixedly connected to one end of the L-shaped rod. A connecting rod is hinged to the edge of the upper surface of the disk. Water flowing through the spherical shell provides kinetic energy to the blades, thereby driving the rotating shaft to rotate. This, in turn, drives the toothed plate to move horizontally back and forth through the disk and the connecting rod, thereby driving the toothed ring that meshes with the toothed plate to rotate back and forth, which in turn drives the fertilizer spraying pipe to rotate back and forth, which in turn drives the nozzle to swing back and forth, thereby expanding the spraying range.

[0006] Preferably, the spherical shell and the fertilizer spraying pipe are connected by a flexible hose, through which the fertilizer solution inside the spherical shell is introduced into the fertilizer spraying pipe.

[0007] Preferably, a water pump is fixedly connected to the water inlet port of the water pump, and the water pump penetrates the top wall of the fertilizer tank.

[0008] Preferably, a water outlet pipe is provided between the water outlet port of the water pump and the spherical shell.

[0009] Preferably, the fertilizer tank is symmetrically equipped with casters, which drive the device to move.

[0010] Preferably, a handle is fixedly connected to one side of the outer wall of the fertilizer tank.

[0011] In the above technical solution, the fertilizer spreading mechanism of the fertilizer spreading vehicle provided by this utility model has the following beneficial effects:

[0012] This invention utilizes blades, a spherical shell, a disc, a connecting rod, a toothed plate, and a toothed ring. Water flowing through the spherical shell provides kinetic energy to the blades, which in turn drives the rotating shaft to rotate. This, in turn, causes the toothed plate to move horizontally back and forth via the disc and connecting rod, which in turn drives the toothed ring, which meshes with the toothed plate, to rotate back and forth. This, in turn, causes the fertilizer spreading pipe to rotate back and forth, which in turn causes the nozzle to swing back and forth, thereby expanding the spraying range and making the spraying more uniform, improving the fertilizer spreading effect. Furthermore, it eliminates the need for an additional drive source to drive the fertilizer spreading pipe to rotate back and forth, thus saving on equipment manufacturing costs.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown, a fertilizer spreading mechanism for a fertilizer spreading vehicle includes a fertilizer tank 1. A water pump 2 is fixedly installed on the top of the fertilizer tank 1. A spherical shell 4 is connected to the water outlet of the water pump 2. A rotating shaft 18 is rotatably mounted inside the spherical shell 4. Blades 19 are fixedly connected in a circular array on the rotating shaft 18. A disc 5 is fixedly connected to the top of the rotating shaft 18. A second fixing rod 16 is fixedly connected to the outer wall of the fertilizer tank 1. A second limiting sleeve 15 is fixedly connected to one end of the second fixing rod 16. A fertilizer spreading pipe 10 is rotatably arranged and communicates with the spherical shell 4. A nozzle 11 is arranged in an array on the fertilizer spreading pipe 10. A toothed ring 9 is arranged in an array on the fertilizer spreading pipe 10. A first fixed rod 13 is fixedly connected to the second fixed rod 16. A first limiting sleeve 14 is fixedly connected to the upper end of the first fixed rod 13. An L-shaped rod 7 is slidably arranged inside the first limiting sleeve 14. A toothed plate 8 that meshes with the toothed ring 9 is fixedly connected to one end of the L-shaped rod 7. A connecting rod 6 is hinged to the edge of the upper surface of the disk 5.

[0022] Specifically, the water pump 2 is started to pass the fertilizer water in the fertilizer tank 1 into the spherical shell 4, then through the spherical shell 4 into the fertilizer spreading pipe 10, and then sprayed out through the nozzle 11 to spread fertilizer.

[0023] Furthermore, the water flowing through the spherical shell 4 provides kinetic energy to the blades 19, thereby driving the blades 19 to rotate, which in turn drives the rotating shaft 18 to rotate. The rotation of the rotating shaft 18 drives the disk 5 to rotate, which in turn drives the end of the connecting rod 6 that is hinged to the disk 5 to rotate with the disk 5. This causes the other end of the connecting rod 6 to pull the L-shaped rod 7 to slide back and forth in the first limiting sleeve 14, thereby driving the toothed plate 8 to move horizontally back and forth, which in turn drives the toothed ring 9 that meshes with the toothed plate 8 to rotate back and forth, thereby driving the fertilizer spreading pipe 10 to rotate back and forth, which in turn drives the nozzle 11 to swing back and forth, thereby expanding the spraying range and making the spraying more uniform, improving the fertilizer spreading effect. Moreover, no additional drive source is needed to drive the fertilizer spreading pipe 10 to rotate back and forth, thereby saving the equipment manufacturing cost.

[0024] As a further embodiment of this utility model, the spherical shell 4 and the fertilizer spreading pipe 10 are connected by a flexible hose 12.

[0025] As a further embodiment of this utility model, a water pump 2 is fixedly connected to the water inlet port of the water pump 2, and the water pump 17 penetrates the top wall of the fertilizer tank 1.

[0026] Specifically, the water pump 2 is started to draw out the fertilizer water from the fertilizer tank 1 through the water pumping pipe 17.

[0027] As a further embodiment of this utility model, a water outlet pipe 3 is provided between the water outlet port of the water pump 2 and the spherical shell 4.

[0028] Specifically, the fertilizer water drawn out by the pumping pipe 17 is introduced into the spherical shell 4 through the water outlet pipe 3.

[0029] As a further embodiment of this utility model, the fertilizer tank 1 is symmetrically provided with moving wheels.

[0030] As a further embodiment of this utility model, a handle is fixedly connected to one side of the outer wall of the fertilizer tank 1.

[0031] Working principle: The water pump 2 draws fertilizer from the fertilizer tank 1 through the pumping pipe 17. The fertilizer is then directed through the outlet pipe 3 into the spherical shell 4, then through the hose 12 into the fertilizer application pipe 10, and finally sprayed out through the nozzle 11. The water flowing through the spherical shell 4 provides kinetic energy to the blades 19, causing them to rotate. This rotation drives the rotating shaft 18, which in turn drives the disc 5. The rotation of the disc 5, in turn, drives the connecting rod 6, which is hinged to the disc 5. One end rotates with the disc 5, thereby pulling the L-shaped rod 7 back and forth through the other end of the connecting rod 6 to slide back and forth in the first limiting sleeve 14, thereby driving the toothed plate 8 to move horizontally back and forth, thereby driving the toothed ring 9 that meshes with the toothed plate 8 to rotate back and forth, thereby driving the fertilizer spreading pipe 10 to rotate back and forth, thereby driving the nozzle 11 to swing back and forth, thereby expanding the spraying range, making the spraying more uniform, improving the fertilizer spreading effect, and eliminating the need for an additional drive source to drive the fertilizer spreading pipe 10 to rotate back and forth, thus saving the equipment manufacturing cost.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
