Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a mud of a groove digging machine capable of discharging the mud generated when deep digging is performed by a claw-shaped rotary onto the ground on both sides of the working groove. Discharge guide device.

[Prior Art] Conventionally, in a groove digging machine configured to equip a rear portion of a machine body with a claw-shaped rotary that can perform deep groove digging while rotating in an up-cut type, a discharge also serving as a cover from above the rotary to a lateral side. The guide plate was extended so that the excavated mud was guided from the discharge guide plate and discharged laterally.

[Problems to be solved by the invention] In such a structure, in a state in which the mud repelled by the up-cut type rotary hits the upper discharge guide plate,
A part of it fell into the working groove, which required several steps of deep trenching, resulting in poor efficiency.

[Means for Solving the Problem] The present invention solves such a problem and enables deep trench digging to be favorably carried out in a single step, and therefore, it is possible to rotate in an up-cut type. In the groove digging machine, which is equipped with a claw rotary (1) capable of deep digging, on the rear part of the machine body, in the rear of the rotary (1), a soil culture plate having a width substantially the same as the width of the working groove (A). (2)
Are installed close to each other, and at the upper rear of the cultivation soil plate (2),
The front portion of the soil guide plate (3) is fixed, and the soil guide plate (3) is formed so that slopes (16a) (16b) extending from the center to both sides are lower toward the rear and outside. , The slopes (16a) (16b) at the rear edge of the upright surface (17
a) (17b) are provided, and slopes (16a) (16b) and upright surface (17
a) Both sides of the lower end of (17b) extend to both sides of the work (A) above the ground to guide the mud to flow down.

[Operation] Therefore, immediately after excavation by the rotary, it is possible to satisfactorily make a groove by exposing the groove by the soil culture plate, and the upcut type rotary allows the mud soil to be splashed upward on the rear side on the soil guide plate. While accepting
As it is, both sides of the work groove can be guided and released on the ground.

Example Next, an example shown in the drawings will be described.

FIG. 1 shows a side view of the entire trench digger. The engine (6) is mounted on the front side of the mission case (5) having wheels (4) mounted on both sides of the lower part, and the mission case (5) A handle (7) extends from the upper part of the vehicle to the rear side of the fuselage, and a transmission case (10) in which a transmission shaft is installed in a rotary frame (9) connected to the rear of the mission case (5) via a rear hitch (8). The transmission case (10) is connected to the transmission case (5) via the counter case (11), and the transmission case (10) is installed on both sides of the lower gear case (10a). A cut type claw-shaped rotary (1) is mounted on each shaft, a rotary tillage treatment rotary (12) is vertically provided below the gear case (10a), and both rotary ( The upper part of 1) is covered respectively It is constructed by installing both rotary covers (13).

(2) is a cultivating plate, the lateral width of which is approximately the same as the lateral width of the groove (A) and the height of which is approximately the same as the diameter of the rotary (1). Connecting fittings (14)
A stay (15) having a lower portion attached to the rotary frame (9) is erected so that the soil culture plate (2) approaches the rear of the rotary (1) and is vertically adjustable.

Also, a soil guide plate (3) is provided on the upper rear of the cultivating soil plate (2).
The soil guide plate (3) is formed such that both slopes (16a) (16b) extending from the center to both sides are lower toward the rear and outside, and the soil guide plate (3) is The rising surfaces (17a) (17b) of the rear edge extending toward one side are formed so as to extend obliquely rearward in the plane and incline toward the rear, and both slopes (16a) (16b) and both rising surfaces (17a) ) (17b) is formed so that both sides (3a) and (3b) of the soil guide plate (3), which is the lower end side thereof, extend above the working groove (A).

Therefore, while the aircraft is moving forward in the direction of the arrow (a) and the rotary (1) is excavating while rotating in the up-cut type as shown by the arrow (b), the soil plate () behind the rotary (1) is By 2), it becomes possible to make a groove by exposing the groove, and the mud that is piled up on the upper side of the soil slab (2) and the rotary (1) jumps upward and rearward as shown by the arrow (C). When the mud to be removed is received on the soil guide plate (3), the third
As shown by the arrows in Figures and 4, respectively, both slopes (16
a) While flowing down on (16b), guided by both upright surfaces (17a) (17b), discharged from both sides (3a) (3b) to the ground on both sides of the working groove (A), respectively. As a result, it is possible to dig a deep groove so that the mud does not enter the working groove (A).

[Effects of the Invention] As described above, the present invention is such that, immediately after the rotary (1), the soil is raised by the culture soil plate (2) while the groove is exposed, and the upcut rotary (1). ) And the mud that is splashed upwards to the rear side are guided downward by the soil guide plates (3) to both sides of the working groove (A) above the ground, so that deep dirt is not left in the working groove (A). It is possible to reliably and satisfactorily perform, and it is possible to dig a groove efficiently.
