Description

Technical Field

[0001] This invention relates to the field of landscaping construction equipment, and in particular to a landscape grass seed spreading device for large-area uniform sowing of grass seeds. Background Technology

[0002] In landscape gardening and greening projects, the establishment and reseeding of lawns often require large-scale sowing of grass seeds. Traditional manual sowing methods are inefficient, labor-intensive, and difficult to guarantee uniformity, easily leading to seed waste and uneven germination. While some existing sowing machines can achieve a certain degree of mechanization, most have limited functions and fixed sowing ranges, making them difficult to adapt to different terrains and widths. Especially in scenarios such as slopes and large green areas, multiple trips or manual assistance are often required, reducing construction efficiency.

[0003] For example, some simple centrifugal or grooved wheel seeders lack flexibility in adjusting the spreading width and direction, and are prone to clogging when dealing with free-flowing grass seeds. Therefore, it is necessary to provide a specialized device that can achieve long-distance, adjustable-range, and efficient grass seed spreading. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a landscape grass seed spreading device with a reasonable structure, high spreading efficiency, adjustable range, and easy installation on a mobile platform.

[0005] The technical solution of the present invention is as follows: a landscape grass seed spreading device, characterized in that the spreading device is used to be installed on a movable platform, and the spreading device includes: a shell, a cylinder, a fan, a drive motor, a spiral auger, an exhaust pipe, a transition connecting pipe, a spreading pipe and a swing mechanism; The shell is hollow inside, the cylinder is fixedly installed inside the shell, the cylinder has a material hopper with an open upper side, the bottom of the material hopper is provided with a vertical discharge pipe communicating with the material hopper, the drive motor is fixedly installed inside the material hopper, the drive motor shaft is provided with the spiral auger, and the spiral auger is inserted into the discharge pipe; The fan is located inside the housing. The housing has an air inlet and an outlet. The fan has an exhaust pipe. The lower end of the discharge pipe is connected to the exhaust pipe. The exhaust pipe extends outward from the housing through the outlet. The outlet of the exhaust pipe is provided with a flexible and bendable transition connecting pipe, which is connected to the dispensing pipe. The housing is provided with a swing mechanism, which is connected to the dispensing pipe to drive the dispensing pipe to swing left and right.

[0006] Furthermore, the lower surface of the hopper is a slope with one side higher than the other, and the discharge pipe is located at the lower part of the slope.

[0007] Furthermore, a vibrator is installed at the bottom outer side of the cylinder.

[0008] Furthermore, a cylinder cover is detachably installed on the cylinder body, and the cylinder cover is used to cover the hopper.

[0009] Furthermore, the fan is a centrifugal fan.

[0010] Furthermore, the filter connecting pipe is a corrugated pipe made of flexible plastic material, with one end of the corrugated pipe fixedly sleeved on the exhaust pipe and the other end fixedly sleeved on the dispensing pipe.

[0011] Furthermore, the swing mechanism includes a collar, a swing rod, and a swing motor. The swing motor is fixedly installed inside the housing, and the motor shaft of the swing motor is fixedly connected to the swing rod. The housing is provided with a clearance hole, and the swing rod extends outward from the clearance hole and can swing within the clearance hole. A collar is fixedly installed on the dispensing tube, and the collar is fixedly connected to the swing rod.

[0012] Furthermore, the mobile platform is a motorized tricycle, which is equipped with a battery and a controller. The battery is used to power the electrical components of the spreading device, and the controller is used to control the operation of the spreading device.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This device primarily utilizes a spiral auger for quantitative and controllable delivery of grass seeds, followed by a powerful airflow generated by a blower to propel the seeds long distances through a spreading pipe. Notably, a swing motor drives the spreading pipe to oscillate left and right, allowing for flexible adjustment of the spreading fan width and direction, achieving large-area uniform coverage. The entire system can be easily installed on mobile platforms such as motorized tricycles, powered by an onboard battery and centrally controlled by a controller. This enables mobile, automated, and highly efficient grass seed spreading operations, significantly reducing labor intensity and improving spreading uniformity and construction efficiency. It is particularly suitable for large-area grass seed spreading projects in gardens, green spaces, slopes, and sports fields.

[0022] like Figure 1 As shown, this embodiment provides a landscape grass seed spreading device installed on a motorized tricycle. The device mainly includes a shell 1, a cylinder 2, a drive motor 5, a spiral auger 6, a fan 8, an exhaust pipe 11, a transition connecting pipe 13, a spreading pipe 14, and a swing mechanism.

[0023] The shell 1 is a sealed box structure with a hollow interior, providing installation space and protection for all components. The cylinder 2 is fixedly installed inside the shell 1 by means of brackets or welding. The upper part of the cylinder 2 forms an open hopper 3 for holding grass seeds. The bottom of the hopper 3 is designed as a sloped surface, and a vertical discharge pipe 4 is welded to the lowest point of the slope. A vibrator 7 is also installed on the outer bottom of the cylinder 2 to assist in the feeding process.

[0024] The drive motor 5 is fixed to the inner wall or top of the hopper 3 via a mounting base, and its output shaft extends downward. The spiral auger 6 is fixedly mounted on the output shaft of the drive motor 5 and inserted downward into the discharge pipe 4. When the spiral auger 6 rotates, it can push the grass seeds in the hopper 3 downward along the discharge pipe 4.

[0025] The blower 8 is preferably a centrifugal blower, fixedly installed inside the housing 1 at the bottom or side. An air inlet 9 is provided on the side wall of the housing 1 to ensure the air intake requirements of the blower 8. An exhaust pipe 11 is connected to the air outlet of the blower 8. The lower outlet of the discharge pipe 4 is connected to the side wall or top of the exhaust pipe 11, allowing falling grass seeds to directly enter the airflow channel of the exhaust pipe 11. The exhaust pipe 11 extends horizontally rearward and protrudes outward through an outlet 10 provided on the rear wall of the housing 1.

[0026] To allow for flexible adjustment of the spreading direction, a flexible transition connecting pipe 13 is connected to the outlet end of the exhaust pipe 11 extending out of the housing. In this embodiment, the transition connecting pipe 13 is made of plastic corrugated pipe, and its two ends are tightly fitted onto the outlet of the exhaust pipe 11 and the inlet of the spreading pipe 14 by clamps, ensuring airtightness while allowing for bending at a certain angle.

[0027] The spreading pipe 14 is a straight pipe or a slightly tapered pipe, with the grass seed outlet at its end. A collar 15 is fixedly fitted in the middle of the spreading pipe 14.

[0028] The swing mechanism drives the dispensing tube 14 to swing left and right. The swing motor 17 is fixed inside the housing 1 near the outlet 10. One end of the swing rod 16 is fixedly connected to the output shaft of the swing motor 17. A corresponding elongated clearance hole is provided on the housing 1, through which the other end of the swing rod 16 extends outward. The extended end of the swing rod 16 is fixedly connected to the collar 15 on the dispensing tube 14 (e.g., by welding or bolting). When the swing motor 17 rotates, it drives the swing rod 16 to swing left and right within the range defined by the clearance hole 18, thereby driving the entire dispensing tube 14 to swing left and right around the corrugated pipe connection point via the collar 15.

[0029] A cover 12 is detachably installed on the top of the cylinder 2 for closing the hopper 3 when not in operation.

[0030] In this embodiment, the entire spreading device is fixed to a motorized tricycle via a base or bracket. The motorized tricycle is equipped with a battery 18, which powers the drive motor 5, fan 8, vibrator 7, and oscillating motor 17. A controller is installed in the driver's cab, which has control knobs, buttons, or a touch screen for individually or in combination to control the start / stop and speed of the drive motor 5 (adjusting the feeding rate), the start / stop and wind speed of the fan 8 (adjusting the projectile force and distance), the start / stop of the vibrator 7, and the start / stop, oscillation angle, and frequency of the oscillating motor 17 (adjusting the spreading fan width and uniformity).

[0031] During operation, the operator drives the tricycle at a suitable speed. The equipment is started by the controller, and grass seeds are quantitatively conveyed from the hopper 3 to the exhaust pipe 11 through the screw conveyor 6. They are carried by the high-speed airflow generated by the fan 8, accelerated by the corrugated pipe 13, and then evenly and fan-shapedly scattered onto the ground from the outlet of the left-right swinging spreading pipe 14. By adjusting various parameters, it can easily adapt to the requirements of different grass seed varieties, different spreading densities, and different working widths.

[0032] In summary, this device has the following characteristics: 1. It achieves a combination of mechanical quantitative conveying of grass seeds and pneumatic long-distance sowing, resulting in long sowing distance and good uniformity.

[0033] 2. Through a unique swing mechanism design, the spreading pipe can swing left and right, flexibly adjusting the spreading range to adapt to working surfaces of different widths.

[0034] 3. The overall device has a compact structure and is suitable for installation on commonly used mobile platforms such as motorized tricycles, enabling continuous and efficient operation while on the move and greatly improving the efficiency of landscaping construction.

[0035] 4. Measures such as using vibrators to assist in feeding and sloping feed hopper design effectively prevent grass seeds from clogging and ensure continuous operation.

[0036] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
