Abstract

PROBLEM TO BE SOLVED: To form a firm ridge by supplying soil to a ridge-forming part, firmly tightening the upper surface of the formed ridge with a rotating flat plate and tightening the inner surface of the ridge with a rotating vertical rotary drum. SOLUTION: This ridge-forming machine is drawn by a tractor to successively form a ridge in the moving direction and is provided with a soil-gathering apparatus 3 and a ridge-forming apparatus. The soil-gathering apparatus 3 digs and throws soil by the rotation of several digging claws 8 and continuously supplies the soil to the ridge-forming part. The ridge-forming apparatus has a vertical rotary shaft having a vertical rotary drum 17 for finishing the inner side face of the ridge and an upper rotary flat plate for finishing the upper face of the ridge. The rotary flat plate is placed coaxially to the rotary shaft and rotated integrally with the vertical rotary drum 17.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ridge forming machine which is attached to a traveling vehicle and sequentially forms ridges in the traveling direction.

[0002]

2. Description of the Related Art In a conventional ridge forming machine, a mechanism for hitting a ridge upper surface and a side surface is widely used, and in recent years, as proposed in Japanese Patent Application Laid-Open No. Hei. It has a ridge forming device consisting of a conical rotating body that forms the ridge side surface, and sets the peripheral speed of the rotator of the ridge forming device faster than the traveling speed of the towing vehicle to knead the ridge outer surface by the slip action. Some try to compact tightly.

However, in such a conventional ridge forming machine, the ridge upper surface is intended to compact the ridge to the hem portion by the conical rotating body forming the ridge side surface. Since the round shaft rotating body that forms the slab has a small diameter and a limited peripheral speed, the tightening force on the upper surface of the ridge and the shoulder portion has to be weakened, and there is a drawback that it easily collapses.

[0004]

In order to solve the above-mentioned problems, the ridge forming machine according to the present invention employs the following means. That is, a ridge forming machine that is attached to a traveling vehicle and sequentially forms ridges in the traveling direction, and a soil filling device that supplies soil to the ridge forming portion in a heaped state, and compacts the soil accumulated in the ridge forming portion. And a ridge forming device for forming a ridge, wherein the ridge forming device coaxially connects an upper flat rotary plate forming an upper surface of the ridge and a vertical rotary drum body forming an inner side surface of the ridge. It is characterized by being forcedly driven. In the ridge forming machine according to the present invention, the vertical rotating drum body may be formed in a conical shape with a tapered lower end. In the ridge forming machine according to the present invention, the vertical rotating drum body may be configured to rotate about an axis line that is eccentric with respect to the rotation axis. In the ridge forming machine according to the present invention, a protruding portion may be provided on the peripheral surface of the vertical rotary drum body, or the peripheral surface may be polygonal.

[0005]

When the towing vehicle is advanced, the earth embankment device and the ridge forming device are operated, so that the earth embankment device continuously supplies the soil to the upper surface portion and the side surface portion where the old ridges have collapsed in a heaped state. 3, it is formed as shown in the operation diagram of FIG. That is, the forcibly driven upper flat rotary plate presses down and compacts while kneading the heaped soil supplied to the upper surface of the old ridge, and at the same time, the vertical rotary drum body appropriately slips at high speed (3). In the meanwhile, it works as a tightening tool while kneading up the soil on the inner surface of the ridge.

When the vertical rotary drum is formed in a conical shape with a tapered lower end, it is rotated along the natural inclined surface of the inner surface of the ridge so that the finished surface is clean. Further, when it is configured to rotate around an axis line that is eccentric with respect to the rotary shaft of the vertical rotary drum, a horizontal intermittent rocking pressure is applied to the upper surface and the inner side surface of the ridge to perform a firm tightening action. . Further, if a protrusion is provided around the vertical rotary drum or if the peripheral surface is polygonal, the structure is simplified and the inner surface of the ridge is kneaded while appropriately beating.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a perspective view illustrating a ridge forming machine, FIG. 2 is a plan view of the ridge forming machine, FIG. 3 is a side view illustrating an operation, and FIG.
[Fig. 4] is a front view for explaining the action. 5 and 6 show another embodiment.

Reference numeral 21 denotes a machine frame to be mounted on the towing vehicle 6, which is connected to a three-point link of the tractor in this embodiment.
Reference numeral 7 denotes a mission, which is supported in the center of the machine frame 21 and is input from the tractor PTO shaft (omitted) through the universal joint 22 to transmit power to the first speed change unit 9 and the second speed change unit 10. .

Reference numeral 3 denotes an earth embankment device comprising several excavating claws 8 and a guide cover 4. The excavating claws 8 are rotated in the direction F2 by the main shaft 20 projecting from the first speed change portion 9 to guide the cover 4. It goes up inside the ridge and rises to the ridge forming part 2. The guide cover 4 is formed of a rear cover 15, an upper cover 12, and the like.

Reference numeral 5 denotes a ridge forming device, which comprises an upper flat rotary plate 16 forming an upper surface of the ridge and a vertical rotary drum body 17 forming a page (4) on an inner side surface of the ridge. The upper flat rotary plate 16 is composed of a horizontal face plate and a brim-shaped guide plate 18 inclined at the periphery. The vertical rotary drum body 17 is formed concentrically with the above-mentioned upper flat rotary plate 16 and is integrally formed. Reference numeral 11 denotes a rotary shaft projecting downward from the second transmission portion 10, and the boss 2 provided on the upper flat rotary plate 16
Inserted in 3 and fixed. The rotation speed of the rotary shaft 11 of the second speed change unit 10 is set so that the peripheral speed of the outer surface of the rotary drum body 17 is faster than the working speed of the towing vehicle 6.

FIG. 5 shows a structure in which the vertical rotary drum body 17 is rotated around an eccentric axis line.
The upper flat rotary plate 16 is concentrically connected to the vertical rotary drum body 17 on the rotary shaft 11 protruding from the rotary shaft 11, and the boss 23 provided with the center of rotation eccentric to the upper flat rotary plate 16 is inserted and fixed. Occasionally, only the eccentric portion of the drum body is guided and tapped.

FIG. 6 shows another embodiment of the vertical rotary drum body. In FIG. 6A, a plurality of vertical protrusions 19 are provided below the conical drum body 17.
(B) is a vertical plane portion 2 on the outer surface of the conical drum body 17.
