Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a lawn boring machine for interstitially boring lawn vegetation, and removes a clod (hereinafter referred to as a core) generated by boring. , A core collecting device for collecting without scattering around.

(B) Conventional technology It is well known that it is necessary to punch holes in the vegetation in order to activate the lawn and promote its growth. A machine for performing the above has been proposed as disclosed in, for example, JP-A-55-37157.

What is seen in this bulletin etc. is that the punching work can be performed mechanically, but the lumps of holes (commonly called cores) that have been punched out are left scattered around. Therefore, there is a problem that it takes a lot of manpower to clean up after cleaning.

Therefore, the applicant of the present application, in the mechanical work by the lawn punching machine, in order to achieve further labor saving by collecting the cores in series without scattering around them, in order to further save labor, the upper transfer portion of the main conveyor belt A sub-conveying belt is placed in contact with the core conveying path by both conveying belts, and the main conveying belt is stretched and stretched in a substantially horizontal shape at the lower end portion of the lifting conveying path to form a core receiving conveying section. A core collecting device configured so as to communicate with each other and configured to lift and convey the core received in the portion and send the core toward the collecting portion from the upper end portion of the lifting and conveying path has been previously proposed.

(C) Problem to be solved by the invention According to the core collecting device having the above structure, since the core discharged from the lawn punching machine can be punched without being scattered around, the post-collecting work for collecting the core is unnecessary. However, the already proposed one still has a problem in the tension structure of the main and sub conveyor belts as described above, which causes the following problems.

That is, in the already proposed one, the tension and relaxation of the main conveyor belt is
By adjusting the tension mechanism provided for the main conveyor belt,
The tension of the sub-conveyor belt is adjusted by adjusting the tension mechanism provided for the sub-conveyor belt.Therefore, when loosening or tensioning the both conveyor belts during maintenance and inspection, both Since many adjustment parts such as fasteners and actuating parts of the tension mechanism part have to be moved, the operation is troublesome and takes a lot of work, and in particular, the tension between the two conveyor belts is taken into consideration so that they are properly related to each other. There was a problem that was difficult to adjust.

In addition, once the main and sub-conveyor belts are loosened, it is extremely difficult to adjust the tension while re-adjusting the main and sub-conveyor belts. Since the belt is often left alone, the belt is cured because it is left in a tension state, and when it is used after that, belt slip occurs and it is often the case that the core cannot be conveyed.

The present invention is carried out in view of the above situation, and its purpose is to significantly simplify the operation of tensioning and loosening both the main and sub transport belts, while keeping the both transport belts in an appropriate related state. An object is to provide an improved core collection device that facilitates re-tensioning.

(D) Means for Solving the Problems In order to achieve the above-mentioned object, the core collecting device in the present invention comprises a sub-conveying belt which is provided opposite to the upward moving portion of the main conveying belt so that the core is lifted by both conveying belts. An upper transfer path is formed, and at the lower end portion of the lift transfer path, the main transfer belt is stretched in a substantially horizontal direction to form a core receiving transfer section, and the core receiving transfer section is connected to form a core received by the receiving transfer section. In a core collecting device configured to lift and convey and send out from a top end of a core lifting transfer path toward a collecting part, a belt-rolling guide roller arranged to form the core lifting transfer path. Alternatively, one of the floating rollers is installed as a tension roller for tensioning and loosening the both conveyor belts in common.

(E) Operation According to the core collecting apparatus of the present invention configured as described above, the sub-conveying belt is arranged to contact the upward transfer portion of the main conveying belt to form the core lifting transfer path. One of the belt winding guide rollers or floating rollers is provided as a tension roller that both tensions and relaxes in common for both conveyor belts. Therefore, you can simply move this single tension roller. Can be tensioned all at once to be in a proper related state, and the operation of loosening and re-tensioning the conveyor belt during maintenance and long-term storage is significantly easier than the conventional one.

(F) Embodiment One preferred embodiment of the present invention will now be described with reference to the drawings. First, for convenience of explanation, a lawn punching machine (A ) The structure of the main body will be briefly described with reference to FIGS. 4 and 1.

Therefore, the core collecting device (C) of the present invention can be attached to the lawn boring machine (A) as required.

The main body (6) of the core collecting device (C) is frame-shaped in the form of a gate in which side plates are erected on the left and right, and a belt winding roller group of a core transfer conveyor (E), which will be described later, is horizontally mounted on the main body (6). A prime mover (7) for forcibly rotating the core transport conveyor is mounted on the upper part, and a core collecting part (9) can be arranged on the mounting table part (8).

As shown in FIG. 1, the core transfer conveyor (E) is constructed by stretching a main transfer belt (10) and a sub transfer belt (11) around each other.

The main conveyor belt (10) consists of a drive roller (12), a floating roller (13), and a required number of belt guide rollers (1).
4) It is hung by (15), (16), and (17) so as to have a substantially Z-shape or a left-right inverted substantially Z-shape when viewed from the side, and is substantially horizontal from the lower end of the vertical hanging part (10a). The hanging portion bent in the direction is used as the core receiving / conveying portion (10b), and the hanging portion bent in the substantially horizontal direction from the upper end of the vertical hanging portion (10a) is the core sending portion (10c). I am trying.

Further, the sub-transport belt (11) is provided so as to be wound between the floating rollers (18) and (19) which are vertically opposed to each other with a predetermined interval. Further, the one hanging portion is provided so as to come into contact with the upward moving side of the vertical hanging portion (10a) of the main conveyor belt (10) so as to be rotationally moved in the same direction. A core lifting transfer path (D) is formed between the contacting portions of (10) and (11).

The two conveyor belts (10) and (11) are loosely wrapped around each other, and can be appropriately tensioned by a tension mechanism. In the present invention, this tension mechanism is used for both conveyor belts. (10) One of the belt-raising guide rollers or the floating rollers provided to form the core lifting transfer path (D) in (11) is configured by using a tension roller. is there.

That is, whether the belt winding guide roller (14) located at the upper end of the core lifting transfer path (D) or the idle roller (19) located at the lower end of the core lifting transfer path (D) is A tension roller is used, and by moving and adjusting the tension roller, both conveyor belts (10) and (11) can be tensioned and relaxed all at once. In the illustrated example, the upper end of the core lifting conveyor path (D) is used. It is applied to the belt-rolling guide roller (14) located at
Shown in Figures and Figure 3.
