Description

Lawn mower

Landscaping demand for grassland for grassland, such as golf fields, turf football fields, and parks, is increasing day by day, and this trend has brought about a big change in the cultivation of large-scale cultivation in traditional small-scale cultivation methods that had limited procurement. Came. Of course, researches and developments on the improvement of grass species suitable for climate and soil are also actively conducted.

In order to provide timely supply of grass grown in a large grass growing cultivation area on demand, the speed and efficiency of the grass harvesting operation is determined. Conventional grass harvesting methods were purely manpower-dependent. Manual harvesting of grass involves a large number of people, low harvesting efficiency, and a series of operations that take time to harvest the grass and shake off the roots. Therefore, even before transplanting, the roots dry before transplanting, so the mortality rate of grass does not survive, and even if it survives, it is difficult to live long because of poor health.

In order to increase profitability and operate efficiently in the commercialization of grass growing in a large area, it is necessary to harvest grass and sow the root soil so that the seeding and cultivation of grass is not carried out until the transportation and transplanting work is carried out in the near distance and transplanted. Turf must be managed safely and biohazardly. To this end, it is urgent to break away from manpower-dependent grass harvesting methods. The future task in this field is to implement a lawn harvester that can quickly and efficiently perform a series of lawn harvesting operations, such as grass harvesting, lawn cutting, and root dusting, with very few manpower. This saves not only lawn safety but also harvesting costs.

The present invention is a lawn harvester obtained from the results of the research efforts for the purpose of meeting the above expectations, the front end of the chassis is equipped with a traction rod and PTO device for traction and dynamic connection to the agricultural tractor, and also the front of the vehicle From the ground to limit the depth of the rake to the planting surface from the back to the ground, a rake car to dig up the grass on the ground, a rake car is picked up in the air to receive the grass to fly to the rear of the chassis, carried on a conveyor It provides a grass picker installed in the order of the secondary hairs to shake off the dirt that has been buried in the grass falling toward the rear of the chassis. The rake car, the conveyor, and the dirt-bearing car perform a given task while rotating in place in the car object by the engine output of the tractor transmitted through the tractor's PTO device.

In the early stage of running the lawn, which is a grass picker, by hanging the tractor towing the tractor, if the engine power is applied to the PTO device from the driver's seat, the rake turns upside down in the direction of the movement, and the grass is picked up like a rake, and the grass is pulled. They are transported to the rear of the undercarriage on the conveyor that was turning the track, and when the conveyor returns to the return point from the undercarriage, it naturally falls on the slide. Underneath the chute, a chafing brush will shake off the dirt from the grass. On the rear of the chassis, the standard lawn can be removed and the lawn is filled with loose soil and replaced with new ones.

Regardless of the size of the lawn, the amount of grass and the amount of grass collected, this lawn harvester has enough labor cost savings because it is sufficient for two drivers, one driver who drives the tractor and one assistant who replaces the lawn. In the following, it is possible to drastically reduce the number of working people, which makes it possible to increase the efficiency, shorten the time of lawn harvesting work and reduce the working time.

In FIG. 1 and FIG. 2, a towing section 2 is provided at the tip of the chassis 1. The towing section 2 is connected to the rear of the agricultural tractor for the towing key, it is configured to fold so as not to fold the front projection obstacle when not in use.

The PTO device 3 is mounted on the upper end surface of the chassis 1. This PTO system (3) is for driving the rake (4), the conveyor (5) and the dirt (6) by driving the engine output of the tractor to the power output of the tractor and can be separated from the tractor during non-working and storage. In addition, the driven body can be driven simultaneously by directly or indirectly hooking the endless belt between the driven pulley 7 and the rake wheel 4, the conveyor 5 and the driven pulley 6 of each driven pulley. To be.

The rake car 4 installed in the transverse direction in a form rotatable with respect to the traveling direction on the bottom of the front end portion of the chassis 1 attaches the rake 8 to the main surface of the round barrel in the radial direction, and the rake 8 is the front thereof. The grass of the rake is chopped and rotated in the direction of rearing, and the grass collected by the rake (8) is placed on the conveyor (5) installed to return to the return point immediately behind, and is carried toward the rear of the chassis (1). I'm going. On both side chassis 1 of the rake wheel 4, a grounding rod 9 is attached. The ground rod 9 is a limiting element such that the depth to which the rake 8 is driven to the ground is constant.

Conveyor (5) is a carrier that carries the grass collected and mounted on the rake (4) to the rear of the chassis (1), the front return point is collected without disturbing the rotational movement of the wheel roll in the rear of the rake (4) The grass is at a point where it is easy to climb, and the rear return point is at the rear of the chassis (1). Coarse belt conveyors or mesh conveyors are suitable for smoothly transporting the raised grass without slipping forward in the slope section during transportation.

Dirt (6) is installed at the rear of the undercarriage (1) just below the rear return point of the conveyor (5) to be carried on the conveyor (5) to scatter the grass falling naturally to shake off the excess soil on the grass, Similar to the rake car 4, it is installed in a form rotatable in place in the transverse direction with respect to the traveling direction.

Although not shown in these figures, a hanger may be attached to hang the detachable lawn bucket at the rear end of the chassis (1) where it will not interfere with the activity of the dirt. Hanging a bucket on a bucket hanger saves the trouble of receiving the collected grass separately, and standardizing a lawn bucket adds a litter to a litigation vehicle after transportation or transport to a destination, transportation by personnel, and storage convenience.

FIG. 3 briefly illustrates the lawn-harvesting action performed during the operation of the lawn by connecting the above-mentioned tow (2) of the lawn harvester to the tastelessness of an agricultural tractor and connecting the PTO device (3) to the power output of the tractor. When the tractor and the lawn mower move in the direction of arrow a, the rake car 4 returns to the direction of arrow b while taking down the grass every time the rake 8 touches the ground.

Since the grass 11 stamped on the rake (8) is lifted to the rear and is loaded onto the conveyor (5) by the rotary centrifugal force at this time. The grass 11 carried on the conveyor 5 along the direction of arrow c toward the rear of the chassis 1 leaves the conveyor 5 when the conveyor 5 turns to the rear return point and rides the chute 12 on the chute 12. After the natural fall to (6), the grass 11 is scattered by the soil hairs secondary (6) that was rotating in the direction of the arrow d, the remaining dirt buried in the grass bucket (10). When the grass is filled in the grass bucket (10), peel off, change into a new grass bucket and continue to collect grass.

The lawn harvester of the present invention as described above is connected to an agricultural tractor and dragged, driving the rake car, the conveyor, and the dirt whisk with its engine output, picking up the grass of the lawn, pulling it off with a conveyor, and burying it on the stem or root at the final stage. It is configured to shake off the dust and collect and clean up the grass because the grass grown on the lawn is collected as small as a hoe, and the soil that is unnecessary for transportation and transplanting is simply whisked away by simply pulling tow and dynamic connection to the track frame. Since the manpower and labor costs are greatly reduced, and mechanical work, lawn harvesting efficiency is much higher than when manpower is used.

In addition, compared to the manual work of digging and handing off the soil, you can save effort, time and money on the backing of the grass, as well as provide a better condition for transplanting.

The present invention is a lawn harvester that makes it possible to efficiently collect the grass growing from the grass cultivation plant in another place to carry out the batch operation from the stalk to the dust removal to the efficient and quick and easy transplanting with a small number of people. It is about.
