Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled soil spreader used in lawn upholstery work.

[0002]

2. Description of the Related Art The inventor of the present invention has previously proposed Japanese Utility Model Laid-Open No. 62-148005 as a soil spreading machine.

[0003]

The above-mentioned soil spreading machine is a machine for efficiently carrying out the spreading of the soil, which has conventionally been done only by hand. It is intended for short fences planted in. By the way, the inventor of the present application has separately proposed a new and efficient method for growing grass, which is an improvement of the conventional transplanting of grass, which is a short fence planting method, and a spiral roll product for carrying out the method. This is JP-A-2
No. 104216, in which the sand and sand pass through the cut grass that has been decomposed and stretched to form a streak-shaped grass runner as described in the text, but the grass runner itself does not allow passage between two upper and lower mesh nets. It is a method of growing grass that is manufactured by manufacturing a long spiral roll product sandwiched in approximately one row in a factory, and appropriately carrying it to the ground surface that requires grass planting and spreading it on the ground surface. According to this method, the workability is improved by 15 to 20 times compared with the conventional lawn planting work, but the present invention is suitable for spraying on the extended upper surface sandwiched between the nets. The purpose is to provide a soil spreader.

[0004]

According to the present invention, a crawler is adopted as a traveling means, and the soil conveying means is constituted by a belt for horizontally traveling the bottom surface of the soil storage hopper onto the traveling means. A brush roller that rotates with a width dimension substantially the same as the belt width is provided in front of the soil conveying means, and a compaction roller that abuts against the ground surface of the same width dimension is disposed in the lower front portion of the brush roller so as to be vertically movable. To do.

[0005]

[Function] The top and bottom two nets that are spread on the ground surface with a grass runner sandwiched between them are pre-pressed by a compaction roller to efficiently spread the soil while preventing the net from rising. Becomes

1 is a side view of the device of the present invention, and FIG. 2 is a plan view thereof. 1 is a traveling means by a pair of left and right rubber crawlers,
Reference numeral 2 denotes a soil soil conveying means installed on the front side of the apparatus frame F on the traveling means, which is an endless belt 2B that horizontally travels on the bottom surface of the soil soil storage hopper 2A. Reference numeral 3 denotes a transmission means for driving the endless belt, which is driven by an engine 4 installed on the rear surface side of the apparatus frame F to rotate the endless belt 2B in the arrow (a) direction. On the front side of the soil storage hopper 2A, that is, on the front side of the traveling side of the endless belt 2B, there is provided a gate plate 5 for appropriately changing and adjusting an opening gap h from the belt surface. The gate plate 5 is an engine. It can be changed at any time through the lever rod 6 at the pilot seat position on the side of No. 4.

Numeral 7 is a brush roller which is supported on a substantially horizontal plane with the running upper surface of the endless belt 2B and which is rotated at the front edge of the endless belt 2B. The chain wheel 10 is supported by a pair of support brackets 9 and is provided on one end side of the shaft 8 so as to rotate in the arrow (b) direction from the drive chain wheel 11 on the engine 4 side via the chain 12. Has become. The brush roller 7 is provided close to the front end edge of the endless belt 2B, and while scraping the soil soil transferred through the endless belt 2B, the downward direction of action of the centrifugal force, that is, the arrow line ( C) is sprayed in the direction. At this time, reference numeral 12 is a cover for preventing scattering provided on the front side thereof, and the lower end of the cover 12 is formed on a scraping claw plate 13 for performing the earth and sand scrubber action of the rolling roller described below. .

Numeral 14 is a pressure roller arranged at positions separated by a certain distance on the advancing direction side of the crawler, which is freely rotated by a pair of left and right rods 15 protruding from the frame on the crawler side. Is supported and the rod 15
Is movable up and down from the bracket 16 of the apparatus frame F through the hydraulic cylinder 17 in the directions of arrows (d) and (e) about the fulcrum 18 as a fulcrum.
In the direction, the compaction roller 14 is lifted from the ground surface, while the downward movement (e) presses the ground surface with a constant weight, that is, it is extended to the ground surface. The upper surface of the net sandwiching the grass runner in a sandwich shape is rotated in the direction of arrow (f) while being pressed while the crawler is running. In the drawing, 19 is a cockpit provided at a rear position of the device frame F, and 20,
Reference numerals 21 and 22 are a lever for running the crawler, a lever for vertically moving the compaction roller, and a lever for driving the belt, respectively.
Reference numerals 23 and 24 are clutch and brake petals.
A button switch 25 for driving the brush roller is attached to the belt driving lever 23.

Next, the operation of the device of the present invention will be described.
The driver rides on the rear cockpit 19 of the device frame F, depresses the clutch 23 when the engine 4 is started, runs the crawler, and moves the roller upper surface 27 between the grass runners extended to the ground surface 26 to the rolling roller 14. It proceeds while pressing with, and at this time, the soil soil put into the soil soil storage hopper 2A is driven along with the driving of the endless belt 2B on the bottom surface.
By simultaneously rotating the brush roller 7, the brush ends of the brush roller 7 that is taken out to the front edge of the endless belt 2B and rotated are efficiently scattered in the centrifugal direction (C) obliquely downward. At this time, the gate plate 5 is raised upward to increase the opening gap h when the amount of soil dust is small, and is lowered downward when the amount is large. After the soil spraying is completed, the compaction roller 14 is moved to another place while being lifted above the ground surface.

[0010]

As described above, according to the present invention, the upper surface of the net containing the turf runner extended onto the ground surface by the roller compactor 14 is not pressed in advance, that is, the net is stretched. Since the soil is sprinkled on the upper surface,
Since it is possible to spray the soil efficiently with the net being prevented from being lifted at all times, it is not necessary to make a correction in a single operation (the net may partially appear on the ground surface). It is possible to carry out a clean finish of soil spraying work. In the present invention, the use of the crawler as the traveling means 1 means that after the soil is sprinkled, a peculiar wavy rut is formed by the traveling of the crawler on the ground surface. Since it has the effect of reliably pushing it into the interior, a good connection between the net and the ground can be obtained. Further, according to the present apparatus, the soil can be sprayed uniformly with a constant width interval corresponding to the width of the left and right crawlers. In contrast to the conventional random spraying, the present invention is performed in an orderly manner. It is easy to remove, and in particular, the work on the muddy ground surface after rainy rain, which has been difficult in the past, can be suitably performed without any problem. The device of the present invention can also be applied to the spraying of soil on a short fence of a cut grass.
