Description

[Detailed description of the invention] (Industrial application field) This invention cuts trampled turf grass and softens the soil.
It is used as a device to revitalize turfgrass by improving water permeability, air permeability, and absorption of fertilizers, chemicals, etc.

(Prior Art/Leading Problem to be Solved by the Invention) Some conventional machines of this kind are available as large-scale machines manufactured overseas, but they have many problems such as large vibrations and large scratches on the grass. The current situation is that it is hardly used. In addition, there has been a lot of talk recently about the public issue caused by the leakage of agricultural chemicals used on golf courses, and there is an urgent need to establish a technology that can revitalize turfgrass by reducing or eliminating the amount of agricultural chemicals used. . On the other hand, the disparity in the number of visitors is widening depending on the quality of a golf course's green environment, and each golf course is becoming more and more particular about growing and managing turf grass. In view of these circumstances, the present invention attempts to solve the above-mentioned problems by providing a device for activating turf meadows.

(Means for solving the problem) The present invention takes the following technical means to achieve the above-mentioned object. That is, the turf meadow activator is connected to the rear of the tractor and has a plurality of disks disposed at the front lower part, and a knife and a pressure roller that are located in a straight line behind the disk and swing back and forth. It is a machine.

(Example) A set piece (2), (2') and At the same time as fixing the joint link plate (3), the human power shaft (4) is connected to the bearings (5) and (5') in order to transmit the power of the tractor (A) through the joint (D). It is mounted on a shaft and is pulled and driven by the operation of a tractor (A). (6), (6') ---- are disks, and both ends are connected via cylindrical hubs (7), (7') - provided at appropriate intervals at the front lower part of the frame frame (1). The stays (8) and (8') are rotatably attached to the stays (8) and (8') provided in the frame frame (1), and the stays (8) and (8') have multiple mounting holes ( 9), (9') −
and fixed (10), (10'). Further, a gauge hub portion (E) having a larger diameter than the other portions is provided in a portion of the hub (7), (7°).

), and the disks (6) and (6') are arranged so that the rear linear part has a large diameter and the diameters gradually become smaller on the left and right. (26) is a rod, and one end is attached to the arm (24), (24') is a summer jacket (27), and the middle part is a support bin that can be slid up and down on a support part (28) fixed to the frame frame (+). (29), and an adjustment hole (31) for changing the pushing force of the spring (30);
(31') - is provided, and a pressing roller (22),
(22')- are provided with holding holes (32) and (32')- which can hold the turf grass in a state where it is suspended above the grass ground. (33
) is a guide H1 that guides fertilizers, chemicals, etc. to fall into cuts in the turfgrass created by discs (6), (6'') or knives (II), (11'). As shown in Figure 8, the guiding device (33) can be configured to face the cutting target to more reliably drop fertilizer, etc. into the cut, and as shown in Section 9, the guiding device (33) can be configured to face the cutting target.

Next, its effect will be explained.

First, when the Ml of the present invention is connected to the rear part of a tractor (A) and the tractor (A) is operated to drive, the disc (6),
(6') - cuts the turfgrass, and in a straight line behind it, that is, the knife (11) swings roughly where the disc <6>, (6") passed, and (I+') ---- cuts the turfgrass. It infiltrates the sugar source and advances while crushing the turfgrass and turf pit.Then, the turf grass surface is cleared by squeezing the raised turf grass cuts with the rear pressing rollers (22), (22°). Because of this structure, the vibrations cancel each other out, making it possible to provide a machine with less vibration.Also, the knife (+1)
, (11') - installation (]4) is designed to break when it hits a large stone in the ground and becomes overloaded, so damage to the machine can be prevented. Also, the disks (6), (6') - are large diameter gauge hub parts (11), (II') -m provided in a part of the hubs (7), (7'').
- acts on the grass, so it is possible to cleanly crush the grass without causing any dragging or peeling of the grass, and the large diameter parts of the a-ra (22), (22') and - can crush the cut edges of the grass. Since it presses down, it is possible to neatly correct the heaving of the grassland. Furthermore, the swinging knife (Il), (1

Discs (11), (11') - are installed so that the disks (11), (11') - are approximately the same in number, and their swing directions are opposite to each other. Mounting holes (9), (
9') This can be easily done by simply changing -, so the plowing depth can be made shallower or deeper depending on the conditions of the grassland. Furthermore, when applying fertilizers, chemicals, etc. at the same time to promote revitalization of grass meadows, a container (34) is installed on the upper part of the machine, and a knife (11) (II') -
By guiding the fertilizer or chemicals, etc. to the guiding device (33) between the and the pressure rollers (22), (22'), the chemicals, etc. can be injected into the cuts in the turf, and then the pressure rollers (22), (22')-m-
Since it is suppressed by water, there is no surface runoff of chemicals, and effective fertilization or chemical spraying is possible. Therefore, by preventing pollution and containing chemicals, a comfortable environment free of unpleasant odors can be ensured.

(Effects) This invention removes the turfgrass soil that has become hard due to trampling by cutting the turfgrass with disks (6) and (6') and then shaking it.
lvi)-111 are almost evenly distributed between the front and rear rocking frames (12) and the reverse rocking frame (13), making it possible to create a machine with less vibration and good workability. It is effective.
