DETAILED DESCRIPTION

[0021] As shown in the figure Figures 1-5

[0022] The shoulder punching device of the polymer prefabricated irrigation canal is composed of a base 1, a push cylinder 2, a slide plate 3, a fixed frame 4, a punching cylinder 5, and a limiting frame. The base 1 is in the shape of a "concave" section. Symmetrical fixed slide rails 6 are installed on the top end of the base 1. The slide plate 3 is in the shape of a long rectangular strip. Guide sliders 7 are fixedly installed on the corresponding positions of the lower surface of the slide plate 3 corresponding to the slide rails 6. The guide sliders 7 are in the shape of rectangular blocks. Sliding grooves are formed in the guide sliders 7 in the shape of dovetails. The guide sliders 7 are connected with the slide rails 6 in a sliding manner through the sliding grooves. During operation, the slide plate 3 slides along the axial direction of the slide rails 6 under the guidance of the guide sliders 7.

[0023] The fixed frame 4 is fixedly connected with the slide plate 3. The fixed frame 4 is in the shape of a "H" section. The two ends of the fixed frame 4 are welded with the slide plate 3, so that the fixed frame 4 and the slide plate 3 are in a fixed connection.

[0024] The punching cylinder 5 is fixedly installed on the inner side of the fixed frame 4. The purpose of installing the punching cylinder 5 on the inner side of the fixed frame 4 is that the punching cylinder 5 in the fixed frame 4 is limited, which facilitates the subsequent punching operation.

[0025] The punching head 8 is fixedly installed on the piston rod of the punching cylinder 5. The punching head 8 is in the shape of a cylinder. The concave 9 is formed on one end face of the punching head 8. The other end of the punching head 8 is welded with the piston rod of the punching cylinder 5. The end with the concave 9 forms a relatively sharp cutting edge at the circumferential edge of the punching head 8, which facilitates the punching operation of the punching head 8 on the shoulder.

[0026] The opening 10 is formed on the slide plate 3 corresponding to the punching head 8. The opening 10 is in the shape of a circle. The opening 10 and the punching head 8 cooperate to realize the shearing action on the shoulder, so that an opening is sheared on the shoulder.

[0027] ​The fixed frame 4 on both sides of the punching cutter head 8 is respectively provided with a limiting frame, the limiting frame comprises a limiting plate 11, one end of the limiting plate 11 is fixedly installed on the fixed frame 4, a limiting rod 12 is fixedly installed on the other end of the limiting plate 11, a limiting head 13 is fixedly installed on one end of the limiting rod 12, the limiting head 13 is correspondingly arranged with the channel shoulder, in use, the limiting head 13 limits the channel shoulder, effectively avoids the channel shoulder from moving up synchronously with the punching cutter head 8 under the action of friction, so as to facilitate the punching cutter head 8 to carry out the next punching operation.

[0028] The base 1 and the sliding plate 3 are connected through the push cylinder 2, a connecting plate 14 is fixedly installed on the piston rod of the push cylinder 2, the connecting plate 14 is fixedly connected with the sliding plate 3, and the push cylinder 2 is fixedly installed on the inner side of the base 1 through a cylinder mounting frame.

[0029] The channel shoulder punching device is provided with a programmer (model PLCS7-800), the programmer (not marked in the figure) sequentially and orderly controls the punching cylinder 5 and the push cylinder 2 to act.

[0030] In use, the channel shoulder punching device of the high polymer prefabricated irrigation channel can be arranged at the tail end of the high polymer prefabricated irrigation channel 15 production line, the formed high polymer prefabricated irrigation channel 15 moves from the head end to the tail end of the production line, and when the high polymer prefabricated irrigation channel 15 enters the channel shoulder punching device, the high polymer prefabricated irrigation channel 15 still keeps moving in the channel shoulder punching device.

[0031] The programmer starts the punching cylinder 5, the piston rod of the punching cylinder drives the punching cutter head 8 to move downward, when the punching cutter head 8 contacts the channel shoulder, the punching cutter head 8 cooperates with the sliding plate 3 to realize clamping of the channel shoulder, at this time, the programmer starts the push cylinder 2, the push cylinder 2 drives the sliding plate 3 to move synchronously with the moving speed of the high polymer prefabricated irrigation channel, so that the fixed frame 4, the punching cylinder 5 and the limiting frame move synchronously with the high polymer prefabricated irrigation channel 15, in the process that the sliding plate 3, the fixed frame 4, the punching cylinder 5 and the limiting frame move synchronously with the high polymer prefabricated irrigation channel 15, the programmer controls the piston rod of the punching cylinder to continue moving downward, the punching cutter head 8 cooperates with the opening 10 of the sliding plate 3 to realize shearing of the channel shoulder, so that an opening is sheared on the channel shoulder.

[0032] When the opening is sheared on the channel shoulder, the programmer controls the piston rod of the punching cylinder to reset, the piston rod of the punching cylinder 5 drives the punching cutter head 8 to move upward in the process of resetting, since the punching cutter head 8 penetrates the channel shoulder, there is a friction force between the punching cutter head 8 and the channel shoulder, in the process that the punching cutter head 8 moves upward, the channel shoulder will move upward with the punching cutter head 8, in this process, when the channel shoulder contacts the limiting head 13 on the limiting rod 12 of the limiting frame, the limiting head 13 limits the channel shoulder, so as to facilitate the punching cutter head 8 to separate from the channel shoulder.

[0033] When the perforating cutter head 8 is separated from the channel shoulder, the push cylinder 2 is controlled to reset, and the above steps are repeated, that is, a new hole can be punched on the channel shoulder.

[0034] The channel shoulder perforating device drives the sliding plate 3 to move in the axial direction of the sliding rail 6 through the push cylinder 2, and drives the fixed frame 4 and the perforating cylinder 5 to move synchronously through the sliding plate 3; the piston rod of the perforating cylinder 5 extends to drive the perforating cutter head 8 to move downward, and the perforating cutter head 8 cooperates with the opening 10 of the sliding plate 3 to form a shearing action, thereby achieving the perforating operation on the channel shoulder of the polymer prefabricated irrigation channel 15; the perforating device effectively ensures that the hole spacing after the hole is punched is consistent, limits the channel shoulder through the limiting frame, facilitates the cutter head to separate from the channel shoulder, effectively reduces the manual labor, improves the perforating work efficiency, and solves the problem that the inconsistent perforating spacing of the existing polymer prefabricated irrigation channel affects the later assembly.
