Detailed Description

The utility model is further described below with reference to the following figures and specific examples.

Referring to fig. 1, the drain board cutting apparatus of the present embodiment includes a loading mechanism 10 and a cutting mechanism 20, in which:

as shown in fig. 2, the loading mechanism 10 includes a plunger 11 provided with a passage 110 through which the drain board 30 passes. The upper opening 111 of the passage 110 is an insertion inlet of the drain plate 30, and the lower opening 112 of the passage 110 is an outlet of the drain plate 30.

Referring to fig. 3, the loading mechanism 10 further includes a baffle 12, wherein the baffle 12 is movably coupled to the insert rod 11, and when an external force is applied, the baffle 12 is pressed toward an opening 112 at the lower end of the insert rod 11, and is configured to block the outside of the opening 112.

As shown in fig. 4, the cutting mechanism 20 includes a tool holder 22 provided with a blade 21, and a matching holder 23 spaced from and opposite to the blade 21.

During construction:

the drainage plate 30 is first inserted from the opening 111 at the upper end of the insert rod 11 and passes through the channel 110 in the middle of the insert rod 11 at least to the opening 112 at the lower end of the insert rod 11, or is exposed from the opening 112 at the lower end as appropriate.

Next, the insert rod 11 is inserted into the ground of the object, and the drain plate 30 is inserted into the ground below. Referring to fig. 5, in the process, the insert rod 11 is pressed downwards, and mud on the outer side of the baffle 12 generates a reaction force to the baffle 12, as shown by arrow a in the figure, so as to press the baffle 12 tightly towards the lower end opening 112 of the insert rod 11 or onto the drain board 30 (at this time, the drain board is clamped between the edge of the side wall of the opening of the insert rod and the baffle), so as to prevent mud from entering the insert rod 11, and in addition, to ensure that the drain board 30 is not pushed upwards.

Subsequently, referring to fig. 6, the insert rod 11 is withdrawn upward. In this process, the inserted rod 11 no longer applies pressure to the soil below or outside the baffle 12, so that the reaction force of the soil to the baffle 12 disappears, and the baffle 12 no longer blocks the opening 112 at the lower end of the inserted rod 11, thereby allowing the relative movement between the drain board 30 and the inserted rod 11. The drain board 30 is left under the ground, and when the insert rod 11 is completely drawn out, the drain board 30 can be cut off.

Finally, the cutting means 20 is located at a suitable height above the ground and around the outside of the cut to be made in the drain board 30. The lower end of the plunger 11 is now located elevationally above the cutting mechanism 20. The tool holder 22 is located on one side of the drain board 30, and the mating holder 23 is located on the other side of the tool holder 22. The tool holder 22 is pressed against the engaging seat 23 by an external force, and the blade 21 cuts the drain plate 30.

The means for pressing down the plunger 11 (not shown) are known in the art and are not intended to be limiting in the present invention. The drain board 30 can also be pushed into the insert rod 11 by external equipment.

Preferably, the shape of the insert rod 11 is a diamond-shaped column to reduce resistance when pressed into the ground.

Preferably, the opening 112 at the lower end of the insert rod 11 is a chamfered notch, and the plane of the chamfered notch forms an acute angle β with the insert rod 11. In this structure, the reaction force generated by the soil outside the baffle 12 in the direction perpendicular to the plane of the bevel cuts provides the baffle 12 with a pressure force against the bevel cuts, ensuring the blocking action of the baffle 12. In addition, the resistance received by the insert rod 11 in the longitudinal direction thereof is also reduced.

Preferably, the sum of the maximum angle between the baffle 12 and the plane in which the oblique cuts lie and the acute angle β is less than 90 °. When the plunger 11 is pressed down, the reaction force on the earth always presses the stop 12 against the chamfer.

Further, the upper portion of the baffle 12 is rotatably connected to the insert rod 11. Accordingly, the lower portion of the blocking plate 12 may block the opening 112 at the lower end of the insert rod 11.

Referring to fig. 7 and 8, as an embodiment, the baffle 12 is provided with a shaft hole 120, the insertion rod 11 is also provided with a shaft hole 113, and the shaft holes 120 and 113 are provided with a connecting shaft 13, so that the rotational connection can be realized. Wherein, the connecting shaft 13 can also be fixed with any one of the baffle plate 12 or the inserting rod 11.

Alternatively, in other embodiments, the connection structure between the baffle 12 and the insert rod 11 may be modified or replaced.

Further, a spring assembly 14 is arranged between the baffle plate 12 and the insert rod 11.

In some embodiments, in the structure connected by the connecting shaft 13, the spring assembly 14 is a torsion spring sleeved on the connecting shaft, wherein one end 141 of the torsion spring abuts against the insert rod 11 or is fixed with the insert rod 11, and the other end 142 of the torsion spring abuts against the baffle 12 or is fixed with the baffle 12. When the torsion spring is not pressed by the inserted link 11 and the baffle 12, the torsion spring is in a natural balance state, and the inserted link 11 and the baffle 12 are at least separated by a distance (shown in reference to fig. 6) which is not narrower than the width of the drain board 30, so as to allow the drain board 30 and the inserted link 11 to freely move relatively. The torsion spring is configured to generate deformation and restoring force when the baffle 12 is tightly pressed on the insert rod 11 or the drain plate 30, so that when the pressure between the baffle 12 and the insert rod 11 is removed, the restoring force of the torsion spring acts on the baffle 12, so that the baffle 12 moves away from the opening 112 at the lower end of the insert rod 11, and a gap enough for the drain plate 30 and the insert rod 11 to move freely relative to each other is reserved between the two.

In other embodiments, the spring assembly 14 may not be limited to a torsion spring, for example, the spring assembly 14 may be fixed to the baffle 12 or the plunger 11, and when the two are abutted together, the spring assembly 14 is compressed to generate a deformation and a restoring force. Alternatively, the spring assembly 14 may be disposed between the baffle 12 and the insert rod 11 through other mounting structures to maintain the minimum distance between the baffle and the insert rod to accommodate movement of the drain board 30 when no external force is applied.

Preferably, in some embodiments, the spring assembly 14 may also serve as a limit. Specifically, the spring assembly 14 is coupled between the baffle 12 and the insert rod 11, and if the angle between the baffle 12 and the insert rod 11 is too large, the spring assembly 14 is also deformed and restored, so that the angle between the baffle 12 and the insert rod 11 is kept not to exceed a certain upper limit value under the action of no external force, and it is ensured that the baffle 12 always rotates towards the opening 112 near the lower end of the insert plate 11 when the outer side of the baffle 12 is stressed. In use, there is generally no external force pulling the blind, except that the soil exerts pressure on the blind 12 during construction.

Alternatively, in other embodiments, the maximum angle between the blocking plate and the insertion rod may be limited by providing a limiting pin (not shown).

As shown in fig. 1 and 4, the drain board cutting device further includes a tool rest 40.

The tool holder 40 includes a base 41, and a mounting plate 42 provided on the base 41. Wherein, optionally, the mounting plate 42 and the base 41 are fixed together by a connecting bracket 43. The mounting plate 42 is preferably a steel plate.

The mounting plate 42 is provided with a larger insertion hole 420 through which the insertion rod 11 can pass.

The tool apron 22 is fixedly connected with a sliding block 220, and the mounting plate 42 is fixedly connected with a guide rail 421, wherein the sliding block 220 can be engaged with the guide rail 421 in a linear motion manner to form a moving pair, and the sliding block and the guide rail are kept from being separated. It will be readily appreciated that the slider-rail mating coupling between the tool holder 22 and the mounting plate 42 may be further modified or replaced.

When the cutting operation is not performed, the tool seat 22 and the mating seat 23 are separated from each other, and both are respectively located on two sides of the mounting plate 42 in the vertical direction of the insertion hole 420, and are also located on, for example, the lower side (the same side) of the mounting plate 42. When cutting, the drainage plate 30 is located between the tool apron 22 and the mating seat 23, and the tool apron 22 moves towards the mating seat 23 to realize cutting.

Further, a dc reducer 44 is disposed on the mounting plate 42.

Preferably, the tool holder 22 is provided below the mounting plate 42, and the dc speed reducer 44 is fixed to an upper side of the mounting plate 42. In addition, a hole (not shown) is formed on the mounting plate 42 for the rotating shaft 440 of the dc reducer 44 to pass through, so that the rotating shaft 440 of the dc reducer 44 can pass through the mounting plate 42 to the side where the tool apron 22 is located.

A transmission rod 45 is connected between the tool apron 22 and the rotating shaft of the dc reducer 44, wherein the transmission rod 45 is rotatably connected with both the tool apron 22 and the rotating shaft 440 of the dc reducer 44, so that the transmission rod 45 and the linear guide rail 421 between the tool apron 22 and the mounting plate 42 form a crank-slider mechanism, thereby realizing the conversion from the rotation of the rotating shaft 440 of the dc reducer 44 to the linear motion of the tool apron 22.

Further, a long stroke rod 441 is coupled between the rotating shaft 440 of the dc speed reducer 44 and the transmission rod 45, and protrudes in the radial direction of the rotating shaft 440. One end of the stroke rod 441 is fixed to the rotating shaft 440, and the other end of the stroke rod 441 is rotatably connected to the transmission rod 45 to increase a linear stroke in the rotating motion, which is related to the controllable stroke of the tool apron 22. The length of the stroke rod 441 can be adapted according to the stroke of the holder 22.

Preferably, the dc reducer 44 includes a high-speed motor, and outputs a large torque through the reducer, so that the tool post 22 is pushed toward the mating seat 23 at a certain speed to complete the cutting.

As shown in fig. 9, a groove 230 is further formed on the mating seat 23. The groove 230 corresponds in height to the blade 21 and allows the blade edge of the blade 21 to penetrate into the groove 230 when cutting the drain board 30 or after the cutting is completed.

Preferably, the groove 230 is a triangular groove or a triangular-like groove recessed inwardly or matched with the blade edge of the blade 21.

In some embodiments, the drain board cutting device is further provided with at least two travel switches (not shown). One of the travel switches is used to detect the position of the plunger 11. The other stroke switch is used to detect the position of the holder 22.

During construction, the insertion rod 11 has two characteristic positions, including a position where insertion into the ground is completed (referred to as a working position for short) and a position above the ground (referred to as an initial position for short). Correspondingly, the travel switch may be configured such that the plunger 11 is not sensed when the plunger 11 is in its working position, and the travel switch senses the plunger 11 when the plunger 11 is restored from its working position to its initial position.

Similarly, the tool holder 22 has two characteristic positions, including a position where the blade 21 is close to or against the mating seat 23 (referred to as a cutting position for short), and a position away from the mating seat 23 (referred to as a standby position for short). Correspondingly, the travel switch may be configured to not sense the blade holder 22 when the blade holder 22 is in its cutting position, and to sense the blade holder 22 when the blade holder 22 is restored from its cutting position to its standby position.

The signals of the two travel switches are used for outputting to a control system so as to judge whether the corresponding inserted rod 11 or the corresponding tool apron 22 is reset.

In the present invention, the specific type of the travel switch is not limited, and the specific position thereof can be adaptively adjusted according to the need, which are conventional technical means, and thus, are not described in detail.
