According to the apparatus introduced in the above-mentioned Patent Document 1, the inlet for sand and dust is opened along the length direction of the metal cylinder opened on both sides, and the opening is made of a sieve mesh. It is the thing of the structure which provided the handle in the separating tool which covered it and attached the rake, and what was introduced in patent documents 3 also attached the wheel to the frame which stretched the sieve mesh, and the sieve part provided with the handle Since it is a structure that removes pebbles and the like by pulling, it is not suitable for collecting pebbles in a wide bunker.
Moreover, since the sand beach cleaning apparatus described in Patent Document 2 is for cleaning a sand beach by pulling a cylindrical drum provided with a plurality of arms, it collects foreign matter such as pebbles. Is not suitable.

  Therefore, the present invention can efficiently and surely collect pebbles and other foreign matters while moving the earth and sand surface with a power work vehicle using a rocking sieve that sifts out the sand and leaves pebbles and other foreign matters. Accordingly, it is an object of the present invention to provide a self-propelled multipurpose working device that can efficiently collect dust and the like scattered on the soil surface.

The present invention proposes a self-propelled multipurpose working device according to claims 1 and 2 in order to achieve the above object.
That is, the self-propelled multipurpose working device according to claim 1 is:
It is a device that collects pebbles and other foreign substances while moving the earth and sand surface that is equipped with a power work vehicle, or performs leveling work and cleaning work of the earth and sand surface,
It is equipped with an oscillating sieve that sifts earth and sand and leaves pebbles and other foreign matter,
The oscillating sieve body has a cutting edge that is edged with standing walls on both sides in the moving direction and crushes earth and sand at the leading edge in the moving direction,
A support structure that is positioned in front of the power work vehicle and supports the swing screen so as to be swingable, and an eccentric drive structure that receives power from the power work vehicle and swings the swing screen. The power transmission from the power work vehicle to the eccentric drive structure is assumed to be by a belt transmission mechanism ,
The eccentric drive structure includes an eccentric shaft extending in the front-rear direction and a pair of swing transmission shafts driven by the eccentric shaft,
One end side of each of the pair of swing transmission shafts is connected to both sides of the eccentric shaft, and the other end side is connected to the upright walls on both sides of the swing sieve body, respectively. Is.

According to a second aspect of the present invention, there is provided a self-propelled multipurpose working device according to the first aspect, wherein a transmission belt is stretched between the pulleys of the input shaft and the power output shaft of the eccentric drive structure, and the eccentricity The (power) output shaft is located below the input shaft of the drive structure.

According to the present invention, it is possible to efficiently and surely collect pebbles and other foreign matters while moving the earth and sand surface with a power working vehicle with a rocking sieve body that sifts the earth and sand and leaves pebbles and other foreign matters. Garbage scattered on the earth and sand surface can be efficiently collected as necessary.
In addition, the power transmission of the eccentric drive structure is based on the belt transmission mechanism, greatly simplifying the power transmission drive structure from the power work vehicle to the swing sieve body, greatly reducing costs and simplifying maintenance and inspection work. And improved reliability.

  It is a side view showing the whole self-propelled multipurpose working device concerning one embodiment of the present invention.   It is a partial top view same as the above.   It is a partial side view same as the above.   It is a partial exploded perspective view same as the above.

The self-propelled multipurpose working device according to one embodiment of the present invention shown in FIGS. 1 to 4 is a device that collects pebbles and other foreign matters while moving on a bunker surface of a golf course, and sifts sand. It is provided with a rocking sieve body 1 that drops and leaves pebbles and other foreign matters.
This rocking sieve body 1 is a porous or net-like one that sifts out sand, and is edged on both sides in the moving direction with standing walls 2 and 2, and a blade body 3 that scoops the sand of the bunker on the leading edge in the moving direction. And a pebbles or other foreign material reservoir 4 at the rear end edge in the moving direction.
Reference numeral 5 denotes a power work vehicle, and the swing sieve body 1 is mounted on the power work vehicle 5 in front of the power work vehicle 5.

  The swinging sieve body 1 has a support structure 6 that supports the swinging sieve body 1 in a swingable manner. The support structure 6 includes a pair of left and right front and rear direction arms 7 and 7 and a pair of front and rear side arms 8 that connect the front and rear. , 8 to form a unitary structure. In the support structure 6, the rear end portions of the front and rear direction arms 7 and 7 form mounting portions 10 and 10 for the mounting arms 9 and 9 of the power work vehicle 5, and a gauge wheel 11 is provided at the front end portions of the front and rear direction arms 7 and 7. , 11 are provided. The mounting arms 9 and 9 of the power work vehicle 5 can be moved up and down by a hydraulic device.

  The swing screen 1 is attached to both ends 12 of the lateral arms 8 and 8 of the support structure 6 in a swingable state with an elastic member 13 made of vibration-proof rubber interposed. Reference numeral 14 denotes an eccentric drive structure, which has a structure in which the eccentric shaft 16 is eccentrically driven by the rotational force of the input shaft 15 to swing the swing sieve body 1. Reference numerals 17 and 17 denote swing transmission shafts. The input shaft 15 of the eccentric drive structure 14 is linked to the power take-off shaft 18 of the power work vehicle 5 via the universal joint 19. That is, one or a plurality of transmission belts 23 are stretched between the pulley 20 of the input shaft 15 and the pulley 22 of the output shaft 21 of the eccentric drive structure 14 (in the illustrated embodiment, two transmission belts are hung). Passed). The transmission belt 23 is a V belt. The (power) output shaft 21 is positioned below (directly below) the input shaft 15 of the eccentric drive structure 14. The pulley 20 of the input shaft 15 of the eccentric drive structure 14 has a smaller diameter than the output shaft 21, and the output shaft 21 is driven to decelerate. The swing sieve body 1 positioned in front of the power work vehicle 5 is adjusted in height so as to lean backward from the front end side in the moving direction.

  In order to collect pebbles and other foreign matters mixed in the sand of the bunker at the golf course with the self-propelled multipurpose working device configured as described above, the gauge wheels 11 and 11 are operated on the bunker surface to swing. The height position of the sieve body 1 is adjusted so that the blade edge 3 slightly bites into the sand surface and leans backward from the front end side in the moving direction. Then, when the power work vehicle 5 is driven to move the bunker surface, the sand of the bunker is scooped up from the blade edge 3 together with pebbles and other foreign matters, and sequentially moves backward in the movement direction along with the rocking movement. In the process, the sand is sieved off, and pebbles and other foreign substances move further rearward and are stored in the foreign substance reservoir 4. In addition, the foreign material collected in the foreign material reservoir 4 is discharged at an appropriate time.

  The self-propelled multi-use work device according to the present invention is not only for golf course bunker, but also for parks, schools and other open spaces, sandboxes, beaches, riverbeds, open spaces such as ground, farms, etc. In addition to foreign matters, foreign matters such as metal pieces, plastic pieces, glass pieces, dust and the like can be removed and cleaning operations can be performed.
