Description

[Detailed Description of the Invention] [Industrial Application Field] This invention involves drilling a vertical hole in the soil for air intake in order to grow grass at a golf course, etc.2.Collecting the soil clods extracted from the vertical hole. The present invention relates to a main conveyor belt drive roller structure for driving a main conveyor belt of a clod collecting device.

[Conventional technology]

A cylindrical tine is inserted into the soil to form a soil clod (hereinafter referred to as a core).
A clod collecting device that is connected to a vertical hole drilling device for extracting cores, and conveys and collects the cores while being held between a main conveyor belt that is shaped like this when viewed from the side and a sub conveyor belt that is I-shaped is disclosed in, for example, Japanese Patent Laid-Open No. 63-248305. It is known for.

The main conveyor belt is forcibly driven by a main conveyor belt drive roller (hereinafter referred to as the drive roller), but during work, there is a problem in which the main conveyor belt shifts in the axial direction of the drive roller due to differences in load resistance, causing misalignment. . If the main conveyor belt is misaligned, not only will good conveyance of the core be hindered, but the main conveyor belt will rub against side plates provided on the outside, damaging the main conveyor belt and the side plates.

[Problem to be solved by the invention]

This is due to the functional characteristics that the main conveyor belt has a single sheet shape with a considerably wide width, and the distribution of the cores conveyed by the main conveyor belt is not uniform in the width direction. That is, if the distribution of the cores is biased in the width direction, there will be a difference in load resistance, and the main conveyor belt with a larger load resistance will tend to lag behind and shift in that direction. Even if you try to prevent this by increasing the tension of the main conveyor belt in general or by adjusting it on the left and right sides, the effect is incomplete; It must be designed to generate resilience to force a return to normal conditions. For this reason, it is possible to make the center of the drive roller a medium-height shape, but the degree of the medium-height is a problem; if it is less than 5, the suppressing force to prevent positional deviation will be small, and if it is large, the width of the main conveyor belt will be large, so In the case of , the main conveyor belt does not come into contact with the drive roller.

There was a problem that sufficient driving force could not be exerted.

This invention solves these problems,
The purpose of this is to realize a drive roller structure for the main conveyor belt that can effectively restore the position even if the main conveyor belt is about to shift, and that can exert strong driving force over the entire width of the main conveyor belt. It is something.

[Means to solve the problem]

In view of the above problems, the present invention has taken the following measures.

In other words, the soil clot collection device is connected to a vertical hole punching device, and receives, withdraws, discharges, and collects the soil clods extracted by the vertical hole punching device using a main conveyor belt in the shape of a side view and a sub conveyor belt in the shape of a ■.

A main conveyor belt drive roller that forcibly drives the main conveyor belt is formed so that both ends have a diameter smaller than that of the center, and the outer peripheral surface of both ends has a roller whose outer circumferential diameter is approximately the same as that of the center; A main conveyor belt drive roller structure for a clod collecting device, characterized by having a structure in which protrusions that are inclined toward the rear in the rotational direction are protruded from the sides at regular intervals.

We provide the following.

[Effect]

By taking the above measures, in other words, even if the main conveyor belt is about to shift position due to the presence of protrusions at both ends that are inclined in a direction that lags in the direction of rotation toward the center, it is possible to restore the position of the main conveyor belt. Since the outer circumferential diameter of this protrusion is approximately equal to the outer diameter of the central portion, a strong driving force is exerted over its entire width.
