Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a device for spraying sand, fertilizer, etc. onto lawns, artificial turf, etc. at golf courses, parks, stadiums and the like.

[Conventional technology]

A conventional device for spreading grass sand, fertilizer, etc. will be described with reference to FIG. In the figure, (1) is a chassis, (2) is a front tire, (3) is a handle for rotating the front tire (2) to change the direction, (4) is an engine mounted on the chassis (1), Reference numeral 5) is a rear wheel roller suspended under the chassis (1), which is driven by the engine (4) and serves as a driving wheel. (6) is a hopper installed on the chassis (1), (7)
Is a conveyor arranged at the outlet of the hopper (6) and serves to disperse the sand in the hopper (6).

Next, the operation will be described. When the engine (4) is driven, the rear wheel rollers (5) run at walking speed, and the conveyor (7) is driven to scatter sand behind the chassis (1). The operator operates the handle (3) while walking to perform the sand spraying work.

[Problems to be solved by the device]

In the above-mentioned conventional turf sand and fertilizer spreading devices, the hopper (6) is used to sprinkle the sand. In order to achieve this, there was a problem that the grass had to be flattened with a dragonfly or the like as post-work.

The present invention has been made in order to solve such a problem, and to obtain a spraying device for turf sand, fertilizer, etc., which has good workability and is capable of inserting sand, fertilizer, etc. scattered at the same time. With the goal.

[Means for Solving the Problems]

In order to achieve the above object, a spraying device for grass sand, fertilizer, etc. according to the present invention is provided on a chassis so as to be located rearward of a spraying position from a hopper and has an opening on a lower surface which is close to and faces a grass surface. A blower box having a section and an inlet on the upper surface, and a fan rotated by a drive source mounted on a chassis are provided to discharge the wind from the fan from the opening of the blower box.

[Action]

In this invention, sand, fertilizer, etc. are sprayed from the hopper, and at the same time, the fan is rotated to expel the air from the opening of the air blower box. The blowing air shakes the tips of the turf, and the sand, fertilizer, etc., which have been sprinkled, are inserted deeply.

〔Example〕

An embodiment of this invention will be described with reference to FIGS. 1 is a side view, and FIG. 2 is a vertical cross-sectional side view of the blower box part of FIG. 1. The same or corresponding parts as those of the conventional device are designated by the same reference numerals, and the description thereof will be omitted. In the figure,
(8) is a blower box provided at the rear end of the chassis (1), which has an opening (8a) on the lower surface that closely faces the grass surface and an inlet (8b) on the upper surface. (9) is a fan driven by the engine (4), and the casing (9a) is formed integrally with the blower box (8). Reference numeral (10) is a traveling wheel provided on the blower box (8).

When the engine (4) is driven, the rear wheel rollers (5) run at walking speed, and the conveyor (7) is driven to scatter sand behind the chassis (1). At the same time, the fan (9) is driven and the air is discharged from the opening (8a) of the blower box (8), so the hair is shaken by the discharged air and the gap between the grasses that has already been scattered Sand is inserted deeply. By operating the handle (3) while walking, the operator can perform sand spraying work and sand insertion work at the same time.

Although the fan (9) is located outside the blower box (8) in the above embodiment, the fan (9A) may be provided inside the blower box (8A) as shown in FIG. In this case, when the fan (9A) rotates, air is taken into the blower box (8A) from the inlet (8b), and is blown from the opening (8a) to the turf surface as it is. Especially, the air taken into the blower box (8A) is blown to the turf surface along the inner surface of the box. At that time, the sand sprinkled on the surface of the grass moves into the space between the grass because the tip of the grass vibrates by the discharge wind, and is further pushed into the back by the wind pressure.

Further, although the engine (4) is shown as the drive source in the above embodiment, an electric motor or a hydraulic source may be used. Further, in the above description, the sand spraying and the sand inserting have been described, but it is needless to say that the same effect can be obtained by using fertilizer or by mixing both. Further, although the chassis (1) is a self-propelled type that is driven by the engine (4), it may be a towed type.

[Effect of device]

As described above, according to the present invention, it is possible to obtain a workable product in which sand, fertilizer, etc. can be sprinkled and sand, fertilizer, etc. can be inserted at the same time.

[Brief description of drawings]

FIG. 1 is a side view showing an embodiment of the present invention, FIG. 2 is a vertical side view of a blower box portion of FIG. 1, and FIG. 3 is the same view as FIG. 2 showing another embodiment of the present invention. FIG. 4 is a side view showing a conventional device. In the figure, (1) is a chassis, (4) is an engine, and (6)
Is a hopper, (8) is a blower box, (8a) is an opening, (8b)
Is an inlet, and (9) is a fan. The same reference numerals in the drawings indicate the same or corresponding parts.

Claims (1)
