Description

[Detailed description of the invention] Field of industrial application The present invention relates to a device for collecting discharged soil mass generated when drilling a ventilation hole on a turf vegetation surface for growing a lawn. .

2. Description of the Related Art Generally, when a lawn such as a golf course becomes rooted, the grass grows in close proximity to each other, impairing air permeability, causing root rot, or being trodden, resulting in impaired growth. Appears to prevent this from occurring.
A drilling machine is used for drilling a vertical hole of about 10 mm and a depth of about 5 to 10 cm at an appropriate pitch (for example, at an interval of 10 cm) on a turf vegetation surface and supplying sufficient air to a root. The drilling machine is
This is a structure in which a pipe-shaped perforated pipe is attached to a self-propelled vehicle so as to be able to reciprocate up and down, and the extracted soil mass (in the present application, synonymous with a core) is automatically collected by a haiku mass collection device integrated with a drilling machine. There is known a type that collects by a collector, and a type that collects by a collector that follows a drilling machine by pulling or self-propelling. As belonging to the former,
For example, one described in JP-A-63-105601 is mentioned.When treating a large grass surface such as a fairway of a golf course, the storage container of the core and the like must be enlarged, and the apparatus is required. Each time the container becomes large and expensive and the container is filled with the core, the container must be discarded by itself, which is not advantageous in terms of work efficiency. Further, as a device belonging to the latter, there is a clod collecting device described in Japanese Patent Application Laid-Open No. 63-248305. This is a configuration in which the collected cores are conveyed to a predetermined height sandwiched between belts and dropped into a core receiver provided on a chassis, but generally, cores immediately after being removed from a vegetation surface are:
It contains a considerable amount of moisture and has a strong adhesive property, and often hinders the transport function.If force is applied, it deforms and adheres to belts or other transport members, making it difficult to remove it. There was a problem in high efficiency and labor saving, for example, it took time for cleaning management.

Under this background, the present invention aims to continuously and efficiently collect cores and discard the collected cores with the increase in the size and efficiency of lawn drilling machines. It is an object of the present invention to disclose a pick-up machine which can quickly and easily transfer to another carrier to perform the pick-up and removal work of cores.

Configuration of the Invention In order to achieve such an object, the configuration provided by the present invention includes a rotating brush extending in the left-right direction with respect to the traveling direction of the vehicle, and a rotating brush provided near the outer peripheral side surface of the rotating brush. A core pick-up part having a guide cover, a receiving gutter provided along a brush extension direction in a fall area of the core discharged from the core pick-up part, and an edge of the receiving gutter extending upward. A hopper that has a trough bottom plate provided and a conveyor section having a number of scraping pieces that convey the core upward along the trough bottom plate, and faces the upper outlet of the conveyor section and receives the core. And a discharge port provided at a lower portion of the hopper has a bottom cover that can be opened and closed.

Hereinafter, an embodiment will be described in detail with reference to the drawings.

1 and 2 show an embodiment of a pick-up device according to the present invention. A four-wheeled vehicle 1 having connecting portions 1a and 1b with a drilling machine (not shown) has a left and right frame. Between 1c and 1d, there are side plates 2a and 2b firmly supported by horizontal rails 1e and 1f and the like provided between the left and right frames. Below this side plate, a rotating brush 3 extending in the left-right direction with respect to the traveling direction of the vehicle 1 is rotatably supported by a bearing 2c provided at a facing portion of the side plate.

One side of the brush shaft 3a of the rotary brush 3 protrudes from the side plate 2a, and a driven pulley 3b provided at a protruding end thereof is connected to a brush driving output pulley 51 of the engine 50 by a belt 56. The peripheral surface formed by the brush bristle tips of the rotating brush 3 is provided at a position in contact with the ground. 54 is
The transmission is connected to the engine body 50 via a clutch 53, and these are mounted on an engine fixing plate 55 fixed between the side plates 2a and 2b. The rotating brush 3 is configured to rotate in the reverse direction (in the direction of the arrow) with respect to the traveling direction of the vehicle, and the guide cover 4 is provided so as to press the outer peripheral side surface of the rotating brush in the traveling direction. The core pick-up part is formed. Behind such a pick-up part, a receiving gutter 5 having a substantially semicircular cross-sectional shape is formed along a direction in which the rotating brush extends in a state in which one edge 5a is in contact with the outer peripheral side surface of the rotating brush. The left and right ends are fixed between the side plates 2a and 2b. Gutter 5
The edge 5b on the other side forms a trough bottom plate 6a by extending the same diagonally upward while maintaining the same width, while the upper edge 4a of the guide cover 4 also has a trough. A flat box-shaped conveyor trough 6 is formed by extending upwardly in parallel with the bottom plate 6a and connecting and fixing the left and right edges of the trough bottom plate to the left and right edges thereof with a plate.

1g is a support standing upright on the left and right body frames 1c, 1d,
A horizontal rail 1h fixed between the pillars penetrates the conveyor trough 6, and firmly supports and fixes the trough on the vehicle frame.

In the trough 6, a sprocket shaft 8a is pivotally supported between the side plates 2a and 2b at a position corresponding to the center of curvature of the arc formed by the receiving trough 5. A pair of drive sprockets 8 are provided at both ends of the sprocket shaft 8a, and a pair of sprocket shafts 9a are provided near the upper portion of the trough 6 in parallel with the sprocket shaft. Similarly, a pair of driven sprockets 9 are provided at both ends. A pair of left and right chains 10 is stretched between the vertically opposed sprockets, and the length of the receiving gutter between the pair of chains is substantially equal to the length in the left and right direction. , A strip-shaped scraping piece with a length approximately equal to
1 is mounted horizontally at an appropriate pitch to form a slat conveyor as the conveyor unit 7. The trough 6 forms a carry-out port 12 by opening the trough bottom plate 6a side near its upper end, and along this carry-out port 12, a screw conveyor 13 that conveys a core from both left and right ends toward a central portion is formed. Is provided.
13a and 13b are conveyor shafts 1 supported between the side surfaces of the trough 6.
Screw blades provided on both left and right sides of 4 with the directions of the spirals being opposite to each other. A hopper 19 is provided so as to surround the center notch of the guide gutter 13c of the screw conveyor. Reference numeral 20 denotes a bottom cover that covers the bottom opening of the hopper. The bottom cover 20 is rotated around the rotation fulcrum 20b to discharge the core from the bottom opening by removing the hook 20a locked on the hopper side. The conveyor shaft 14 is driven by a belt 9b wound around a slat conveyor and an upper sprocket shaft 9a via a pulley. Also,
The lower sprocket shaft 8a is belt-driven by a conveyor driving output shaft 52 of the engine 50 via a pulley.

Operation The earthmoving machine according to the above-described embodiment is towed by a large lawn drill through the connecting portions 1a and 1b. The core extracted by the punch is picked up by the rotating brush 3, and when the distance between the guide cover 4 and the peripheral surface of the brush gradually increases, the core is released by centrifugal force. The core enters the receiving gutter 5 while rolling on the brush peripheral surface. The core that has entered the receiving gutter is gently conveyed upward along the trough bottom plate 6a by the scraping pieces 11, and partly enters the hopper 19 from the carry-out port 12 and is stored at the bottom of the hopper.
The core that has dropped onto the screw conveyor 13 is moved toward the hopper 19 and falls into the hopper. Thus, when a certain amount of cores are stored in the hopper, the carrier of the transport vehicle is positioned below the hopper 19 and the bottom cover 20 is opened, whereby the transshipment is immediately completed, and the boring and picking are performed again. Will be performed.

In the above embodiment, an example was shown in which the width of the receiving opening of the hopper was reduced by using a screw conveyor. However, this may be another conveyor such as a belt conveyor, or the hopper receiving unit may be omitted altogether. The entrance may be provided along the exit of the conveyor.

Effect The lodge picker gently picks up the core scattered on the lawn surface with a rotating brush without distorting it, and applies the force to offset or combine it to the width of the picking part without applying force to the core. Immediately transported upward by the conveyor section with scraping pieces of equal width, the core is sent to the conveyor exit while maintaining its original shape, so that the earth mass adheres to the transport section as in the past. As a result, troubles such as hindering the operation are greatly reduced. Further, since the core is reloaded instantly by the hopper which is also used as the core storage portion and can be immediately returned to the picking operation, the work efficiency is remarkably improved.
Furthermore, since the configuration is simple, there are advantages such as easy maintenance after use.
