Abstract

PURPOSE:To provide the title collector to contain lawn discharged via a discharge port on the mower, intended to perform lawn containment efficiently, so designed that the body equipped with the mower is provided with a delivery device enabling each collector port 5 to communicate with the discharge port. CONSTITUTION:The body 2 of a tractor is loaded with plural collectors 4, and at every delivery of each of these collectors 4, each collector port 5 is made to communicate with the discharge port 3 through a delivery device installed on the body 2. The lawn cut with a mower 1 is contained through the discharge port 3, via the collector port 5, into the collector 4. When this collector 4 becomes full of lawn, the delivery device 6 is operated so as to make excess weeds to fall onto the ground, and another empty collector 4 loaded is brought into place with its port 5 coming close to the discharge port 3, thus enabling both lawn-reaping work and the cut lawn containment into the collectors to be continued.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a collector for storing cut grass in a tractor mower that is attached to a tractor to cut grass and grass. The collectors are mounted in the form of cassettes, and the turf grass is collected by feeding the collectors one by one to the discharge port of the mower.

(The lawn grass cut by the conventional technology and the planned tractor mower that the invention aims to solve is generally transported and stored by a chute etc. to a collector at the rear of the vehicle body or to a towed wagon. Handling of collectors, wagons, etc. is troublesome, and they are often large.

(Means for Solving the Problems) This invention provides a vehicle body 2 equipped with a mower 1, and a collector 4 for accommodating the grass discharged from the discharge port 3 of the mower 1. The collector of the tractor mower has a configuration in which a feeding device 6 which is freely hookable and feeds out three parts is provided.

(Operation and Effect of the Invention) A plurality of collectors 4 are mounted on the tractor body 2,
While the collector 4 is fed out toward the discharge port 3 of the mower 1 by the feeding device 6, the collector port 5 can be communicated with the discharge port 3 each time each collector 4 is fed out. The grass cut by the mower 1 is discharged and stored in the collector 4 from the discharge port 3 through the collector port 5. When the collector 4 is full of grass, it is dropped onto the cutting ground by operating the feeding device 6, and the empty collector 4 is fed out so that the collector port 5 is opened to the discharge port 3.
As a result, the mowing operation and the collection of turf grass can be continued.

In this way, the collector 4 in the tractor body A1 is
By mounting it on the vehicle body 2 in the form of a cassette, each collector can be fed out one by one using the feeding device 6, while switching the collector port 5 to the discharge port 3 of the mower 71 to continue storing the harvest. 4 can be miniaturized to a size that is easy to carry, increasing work efficiency.

(Example) On the ward side, the tractor is a passenger four-wheel vehicle having a driver's seat 7 and a steering handle 8, and is driven by rear wheels 10 driven by an engine 9 mounted on the front part of the vehicle body 2. It is also possible to transmit power to the power take-off shaft. Power is transmitted from this power output shaft to the input shaft of the mower 71, and each cutting blade is rotated to perform reaping. The front wheels 11 are steered by the steering handle 8.

The mower 7l has a structure in which a vertical cutting blade shaft 14 having a cutting blade 13 is disposed below the mower 12, and is rotated by a belt transmission mechanism from an input shaft, and a discharge port 3 is provided on the side. It is configured to open and collect and discharge the grass cut by the rotation of each cutting blade 13 to the discharge port 3 side. 1
5 is a gauge foil, on both the left and right sides of Moore Soduki 12.

Furthermore, they are placed in the front and rear, and are grounded to the cutting surface to maintain a constant mowing height.

Such a mower 1 is mounted on the abdomen of the tractor body 2 so that it can be raised and lowered freely via parallel links, a lift cylinder that expands and contracts with hydraulic pressure, a lift arm, etc. Can be elevated into a posture.

On the discharge port 3 side of the vehicle body 2, a pair of upper and lower support arms 17 which can be vertically movable by means of a bracket 16 are provided in parallel in the upper part, and an inverted U-shaped guide rod 18 is provided at the tip of each support arm 17. Pivotally supported, the guide rod 18 can be moved up and down in parallel by the up and down movement of the support arm 17. The upper side portion 19 of this guide rod 18 may be provided so as to be able to engage with and disengage from the distal end portion of each support arm 17, and may be configured such that the engaged state can be prevented from coming off by a clip mechanism or the like. Note that the support arm 17 may be configured not to rotate upward from the horizontal position.

The collector 4 is elongated in the front-rear direction (formed in a rectangular tube shape, has a collector opening 5 at one end, and has a lid 20 that can be opened up to a certain angle, and is always urged toward the closed side by a spring 21. An engaging part 22 that can engage with the upper part of the mower 12 is projected from the tip of the collector opening 5. Also, the guide rod 18 can be inserted through the front and rear parts of the collector opening 5 to guide it. A guide ring 23 is provided that allows the collector 4 to
When installing the guide ring 23 of each collector 4,
is fitted onto the guide rod 18 to form a loading configuration. 24 is a handle provided near this opening 19, and 25 is a ventilation net provided on the surface of the collector 4, which allows the wind pressure to escape to the outside without allowing the grass blown into the collector 4 to be discharged.

Reference numeral 26 denotes casters, which can be grounded to facilitate handling when carrying with the handle 24.

Prepare a large number of such collectors 4, and guide rod 1
8 with the guide ring 23 of each collector 4 inserted into the stack, open the lid 20 of the lowest collector 4,
When the collector 4 is supported on the upper surface of the mower 12, the collector port 5 of the collector 4 is aligned with the soundness discharge port 3, and is in a communicating state. At this time, the winter clothes 20 of the collector 4 stacked and held on the upper part keep the collector opening 5 closed.

During the mowing operation, the grass that is cut and collected from the grass mower 12 side is blown into the collector port 5 of the collector 4 at the lowest level, which is connected to the discharge port 3, and is stored therein.

When the accommodated collector 4 is full, the lower end of the guide rod 18 is pulled out upward from the guide ring 23 of the lowest collector 4 by pulling the support plate 17 upward. It lost its support and fell downward under its own weight, leaving it on the cutting ground.

The lid 20, which was open at this time, is closed by the spring 21 to prevent the stored grass from spilling out. This collector 4 is carried to a predetermined position.

When the collector 4 containing the grass is removed from the lower end of the guide rod 18, the support arm 17 and the guide rod 18
is returned downward, and by the downward movement of the next stage collector 4, the engaging part 22 of the lid 20 is opened and locked against the upper surface of the mower 12 against the spring 21, and the collector port 5 of this collector 4 becomes the discharge port. 3 will be communicated. In this way, each loaded collector 4 is switched to communicate with the discharge port 3 one by one, and the cut grass is stored therein.

Support arm 17. The vertical movement of the guide rod 18, etc. may be performed manually or automatically. At this time, a full sensor is provided to detect when the collector 4 is full of grass, and the guide rod is moved by the full sensor. 18 may be moved up and down at predetermined timing.

In addition, although the lowermost collector 4 is supported by the lid 20 and the guide ring 23 for the guide rod 18, the front of the lowermost collector 4 is It is also possible to support a portion of the guide rod 18, such as the side part, and to allow the collector 4 to fall down like snow when the guide ring 23 comes off from the guide rod 18.

Needless to say, it is also possible to adopt a structure in which each collector 4 is mechanically switched and dropped.
