Description

[Detailed description of the device] (b) Industrial field of application This device is a perforating excavator for the purpose of improving the growth of lawn, by making vertical holes in the surface of the lawn vegetation and removing the clods in the vertical holes. The present invention relates to a horizontal receiving part structure in a clod collecting device of a perforation excavating work machine that is connected to a clod to collect, convey, collect, and the like.

(B) Conventional technology In order to activate the lawn and promote its growth, this excavation work is essential.

Therefore, this drilling and removing work will be performed according to the time of growth of the lawn, but if this is a small area, it can be done manually. However, if the place is as wide as the fairway of a golf course, you have to rely on machines.

In response to this request, a boring and excavating work machine having various structures has been conventionally developed (for example, JP-A-55-37157) and put into practical use.

(C) Problems to be solved by the invention However, all of the drilling excavators of this type make vertical holes on the lawn vegetation surface and only remove the soil mass in these vertical holes, and even consider the treatment of the removed soil mass. There is no one doing it.
If this is a place like a home garden, there is no problem if the clod is left as it is, but if it is a golf course, it will hinder the play. Therefore, many people were needed to collect this.

Therefore, the inventor has devised a clod collecting device to be attached to such a boring and excavating work machine. What is required of this device is work regardless of the inclination of the ground or the like. It is to reliably receive the clod discharged from the machine and to accurately convey and collect it.

(D) Means for Solving the Problems Therefore, the present invention is attached to a perforation excavating work machine for making a vertical hole in the surface of a lawn vegetation and removing the clod in the vertical hole, and at least the conveyor belt is made substantially horizontal. The horizontal receiving portion for receiving the soil mass that is drawn and dropped and discharged from the perforation earth removing work machine is erected, and the conveyor belt is erected, and is brought into contact with a sub belt that is also erected and driven, In a clod collecting device including a belt feeding mechanism having a vertical feeding unit that nips and conveys the clod with the feeding belt and the sub-belt, the horizontal receiving unit is configured to be rotatable forward and backward. The above-mentioned problem was solved by constantly elastically urging the tip of the horizontal receiving portion toward the ground side with a bullet.

(E) Action As a result, this clod collecting device is integrated with the drilling excavator, and the clod discharged from this is received by its horizontal receiving part and conveyed by the vertical conveying part to a predetermined location for collection. However, at this time, the horizontal receiving part is elastically urged downward, and therefore, regardless of the inclination of the ground, the horizontal receiving part constantly rotates downward, and its good receiving performance. Can be maintained.

(F) Embodiment An embodiment of the present invention will be described below with reference to the drawings.
Fig. 1 is a side view showing the principle of this clod collecting device, Fig. 2 is a side view, Fig. 3 is a plan view, and Fig. 4 is IV- in Fig. 2.
IV sectional view, FIG. 5 is a sectional view taken along line VV of FIG. 3, and FIG. 6 is an overall side view when connected to a boring and excavating work machine.

The clod collecting device according to the present invention has a belt conveyor mechanism 3 including a conveyor belt 1 and a sub belt 2 as main components. Among them, the conveyor belt 1 is arranged in a substantially Z shape in a side view by the driving roller 4 and the passive roller 5. It should be noted that each of the floating rollers 6-
9 is arranged at a predetermined position (these floating rollers 6 to
The number of 9 is not limited to this example. In particular, the floating roller 8 may not be provided. ) The sub belt 2 is supported by two upper and lower support rollers 10 and 11,
The conveyor belt 1 is arranged in a substantially I-shape in a side view along the longitudinal direction (see FIG. 1). Since the sub-belt 2 is in contact with the conveyor belt 1, the sub-belt 2 is also driven by driving the conveyor belt 1. By the way, of these belt transport mechanisms 3, a substantially horizontal lower portion of the transport belt 1 is a horizontal receiving portion 12, a portion which is in contact with the sub belt 2 and stands up is a vertical transport portion 13, and further a vertical transport portion 13. The subsequent horizontal portion is referred to as a horizontal carry-out section 14.

On the other hand, the main body of the clod collecting device A is located at a substantially center of gravity and has a grounding (compressing) roller 15 that effectively receives the weight of the clod collecting device A, and side plates 16 are erected on both sides. The rollers 4 to 11 are fixed to the side plate 16 by using bearing units 17, respectively. The clod collecting device A having such a structure is connected to the connecting arm 18
Is connected to the piercing and earth removing work machine B to perform piercing and earth removing of the lawn vegetation surface and collection of the soil mass. Therefore, first, the outline of the boring and earth removing work machine B will be described. This work machine B is a self-propelled type in which the traveling wheels 20 are driven by the drive source 19 to travel, and the working portion thereof is A perforated pipe called a tine 21 is caused to make an elliptical motion and inserted into the soil, and a lump of soil (called the core) 22 is pushed up into this hole and is discharged from the upper end in a tokoroten manner. Then, at this time, by providing the hood 23 that is open to one side above the tine 21, the core 22 that has risen from the tine 21 is cut by hitting the hood 23 and is opened toward the open side. It is laid down and discharged (see FIG. 1).

By the way, the clod collecting device A is connected by connecting the tip of the connecting arm 18 to the mounting portion 24 or the like at the rear of the perforating earth removing work machine B, and the core 22 discharged in this way is as follows. Collect, transport and collect. That is, the core 22 discharged from the punching and removing work machine B is first received by the horizontal receiving unit 12 of the belt transport mechanism 3 of the clod collecting device A. Next, the core 22 is sandwiched between the conveyor belt 1 and the sub belt 2 by the vertical conveyor 13 and lifted to a certain position. After that, it is conveyed to the horizontal unloading section 14 and falls from there spontaneously, so if you receive an appropriate container 25 (26 is a support table for supporting this) under it, the core 22 will be collected therein. It
Then, at this time, the horizontal receiving portion 12 of the belt transport mechanism 3 can cope with the unevenness of the ground. That is,
Only the passive roller 5 of the conveyor belt 1 is not directly attached to the side plate 16, but a bracket 28 that freely rotates around the pin 27 (may be centered around the floating roller 9) with respect to the side plate 16. Is attached and provided at the tip of this bracket 28. (See Figure 2). By doing so, if the bracket 28 is always bulged downward with the bullet 29 or the like, the passive roller 5 is always in contact with a constant pressing force even if the ground surface is uneven. However, in reality, the passive roller 5
Since it is not possible to directly ground itself, the cover 30 is grounded. Further, when the tine 21 is pierced into the soil and pierced, the periphery of the pierced hole rises, but the ground roller 15 that bears the weight of the above-mentioned clod collecting device A passes over this, and this rise occurs. Level out. Although the above-mentioned bullet 29 is generally a spring, in this case as well, not only the pulling type as in this example, but also the torque type winding around the pin 27 may be used. Further, it may be a balanced type using oil, a pneumatic cylinder or the like. In addition to this, meandering prevention rollers 31 are provided at both ends of important points of the conveyor belt 1 and the sub belt 2.
To prevent the belts 1 and 2 from meandering (see FIG. 4). Further, in order to surely drop the core 22 and to prevent adhesion of mud and the like, a scraper 32 is attached. A spring 33 is provided so as to elastically spring the belts 1 and 2 (see FIG. 5). Further, 34 is a boring and excavating work machine B.
This is a cover for preventing dissipation of the core 22 at the connecting portion when the soil clod collecting device A is connected (see FIG. 6). Besides, reference numeral 35 is a drive source for driving the belt transport mechanism 3, which is separately provided on the side of the soil lump collecting device A, but may be guided from the side of the punching and removing work machine B.

(G) Effects of the Invention Since the invention has been described above, the following effects are expected.

That is, since the clod collecting device A is attached to the drilling excavation work machine B, the core 22 discharged from the drilling excavation work machine B can be collected at the same time as this work. Although labor is saved, at this time, the horizontal receiving portion 12 of the clod collecting device A that receives the core 22 discharged from the punching excavation work machine B is constantly elastically urged downward by the ammunition machine 29 and the like. Since the cover 30 at the tip is in contact with the ground, it follows the inclination of the ground and changes it, and maintains a good horizontal state.
The core 22 that has been dropped from and discharged from is reliably received.

Next, since it is lifted by sandwiching it between the belts 1 and 2 of the vertical transport unit 13, this operation is performed with a simple structure and
It can be achieved with a short space in the front and back. And the core
Since the vertical transport unit 13 can raise 22 to a certain height, the subsequent collecting work and the like are very easy. That is, as in this example, it is only necessary to receive the container 25 below the carry-out port.
