Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mower turfgrass processing apparatus, which cuts turfgrass to be cut and discharges the turfgrass to the outside of a mower deck.

[0002]

The mower in which the blades are rotated in the mower deck to cut turfgrass is suitable for cutting short turfgrass, but when the turfgrass is long, the mower is heavy even if cut by the blade. Sinking at the bottom, collecting action,
And the discharge from the discharge port to the outside of the mower deck is not smooth,
It is difficult to increase efficiency.

[0003]

SUMMARY OF THE INVENTION The present invention relates to a mower deck 3 having a blade 2 for rotating turfgrass which is rotated about an axis 1 in a vertical direction and disposed at an outlet 4 for collecting turfgrass. And a mower turfgrass processing apparatus having a mowing path 5 for guiding light turfgrass out of the collected turfgrass, and a cutter 6 provided below the cutting path 6 for guiding the collected turfgrass while shredding. I do.

[0004]

The turfgrass cut by the rotation of the blade 2 is collected in the mower deck 3 toward the discharge port 4, and the short and light turfgrass is directly discharged outward from the upper weeding path 5. The long and heavy turfgrass is drawn into the cutter 6 below the weeding passage 5, and is discharged outside the machine while being cut short. In this way, the turfgrass harvested and collected is divided into the weeding path 5 and the cutter 6 and both are discharged in a short state, so that clogging at the turfgrass discharge port 4 is reduced. It can improve the processing efficiency of cutting, collecting, and discharging, and can easily cut long turfgrass, thereby broadening the adaptability of cutting.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The mower deck 3 has a blade shaft 1 in the vertical direction.
The lower end has a blade 2 and is mounted in a three-axis form of a central portion and left and right side portions, and forms a collection path 7 for collecting turfgrass to be cut on the front side, and a discharge port 4 at one side end. They are communicating. A cutter 6 (or chopper) is detachably attached to the outside of the outlet 4. Such a mower deck 3
Has a gauge wheel 8 on the front side and a grounding wheel 21 on the rear side.
And the lift link mechanism 1 is provided on the front side of the tractor body 9.
The lift cylinder 11 is attached and mounted by a hydraulic cylinder and expanded and contracted by hydraulic pressure.

Reference numeral 12 denotes a lift arm of the lift link mechanism 10, and 13 denotes a suspension rod for suspending the rear end of the mower deck 3 to a lower limit position. An input shaft 15 interlocked with the power take-off shaft is provided. When the input shaft 15 is driven, the central blade shaft 1 immediately below the gear case 14 is rotated.
6 rotates the left and right blade shafts 1.

The vehicle body 9 has a pair of left and right front wheels 17 and a rear wheel 1 driven by an engine E mounted on the rear.
The rear wheel 18 can be steered by a steering handle 19, and the lift arm 12 is mounted on a front end of the vehicle body 9. Reference numeral 20 denotes a cockpit. The feed path 7 of the mower deck 3 is formed higher than the blade chamber in which the blade 2 rotates, and is formed so as to be wider in the vicinity of the discharge port 4 in order. The cutter 6 attached to the outlet 4 is provided with a pair of upper and lower feed rolls 22 at a lower portion, and is driven around the outer receiving blade 23 and the cutter shaft 25 while holding the grass fed to the outlet 4. It can be sent to the cutting chamber 26 side having the rotary blade 24. Reference numeral 27 denotes an outlet for cutting turfgrass formed below the cutting chamber 26.

The weeding passage 5 is formed along the upper side of the feed roll 22 and the cutting chamber 26 and communicates with the upper part of the discharge port 4 to bypass the cutting chamber 26 from the outside to the lower part. The turfgrass conveyed to the upper part of the discharge port 4 can be guided and discharged from the discharge port 27 together with the turf grass cut in the cutting chamber 26. The transmission of the feeding roll 22 and the cutter shaft 25 is performed by a part of the blade shaft 1 from the transmission case 28.
It can be driven via the internal transmission mechanism.

When there is a long and heavy turfgrass in the turfgrass to be cut by each blade 2, the turfgrass is collected toward the discharge port 4 with the lower part of the collecting path 7 and is clamped by the feeding roll 22 to be cut.
Is cut into the cutting chamber 26, and the short and light turfgrass is collected in the upper part of the collecting path 7 to the discharge port 4 and discharged to the discharge port 27 through the grass discharging path 5 as it is. When cutting short grass, the cutter 6 may be used with the cutter 6 removed from the mower deck 3.

3 and 4 are different from the above example in that:
The cutter 4 is provided between the front wheels 17 with the discharge port 4 of the mower deck 3 being viewed between the left and right front wheels 17 of the rear body 9. The protrusion of the mower deck 3 forward of the vehicle body 9 can be reduced, and the weight balance can be improved. The discharge port 4 of the mower deck 3 is formed immediately after the central blade 2, and a collection path 7 is formed above the rotation surface of each blade 2. The transfer roll 22,
The cutter 6 including the receiving blade 23, the rotary blade 24, and the like is disposed on the front side of the transmission case 29 between the left and right front wheels 17, and opens the discharge port 27 toward the lower side of the transmission case 29. Reference numeral 30 denotes a power take-out shaft provided on the front side of the transmission case 29, which works with the input shaft 15 of the mower deck 3.

6 and 7 are different from the above example in that:
The cutter 6 is integrally formed inside the rear part of the mower deck 3. At the rear side of the mower deck 3, there is provided a cutting chamber 26 communicating with the rotating blade chambers of the left and right blades 2. The outer peripheral wall 31 of the cutting chamber 26 has a blade 23
And a rotary cylinder 32 integral with the cutter shaft 25 in the vertical direction.
The rotary blade 24 is disposed in the supply port 3 of the blade chamber on the right end side.
While cutting the long turf grass sent in from the 3 side between the receiving blade 23 and the rotary blade 24, returning to the blade chamber on the left end side from the return port 34, the ground of the mowing trace is opened from the bottom opening of the mower deck 3. To be released.

In FIG. 5, the rotary blades 24 are arranged on the outer peripheral surface of the rotary cylinder 32 in a drum form. However, as shown in FIG. In FIG. 7, the difference from the above example is that a closing plate 35 whose opening can be changed is provided at the discharge port 4 of the mower deck 3.
Is provided so that the degree of rotation of the turfgrass in the blade chamber can be changed according to the opening degree, and the blade is discharged in a short cut state. The closing plate 35 is connected to the outlet 4
And a turning plate 37 that turns up and down so as to change the degree of opening of the upper half. Reference numeral 38 denotes a rotation shaft, and reference numeral 39 denotes an adjustment hole of the rotation plate 37.

The long and heavy turfgrass is closed by the fixed plate 36 and returned into the rotation of the blade 2 to be short and cut. Is discharged to In FIG. 8, the difference from the above example is that the closing plate 35 is integrally formed with a guide plate 38 along the front wall of the collection path 7, and this base end is pivotally connected to the front side of the collection path 7. 39, the closing plate 35 at the tip is rotated back and forth around the pivotal support 39, so that the front-rear width of the discharge port 4 can be enlarged and reduced. Reference numeral 40 denotes an adjusting hole of the closing plate 35. The guide plate 38 forms a curved surface that is close to the rotating peripheral surface of the blade 2 at the side end portion, and can enhance the guiding of the turf grass and the cutting effect at the time of closing.
