Description

Technical Field

[0001] This invention relates to an improvement of an inlaid patch type dripper screening machine, belonging to the technical field of inlaid patch type drip irrigation pipe production equipment, specifically an inlaid patch type dripper dual-track screening machine and a special cylinder. Background Technology

[0002] Embedded drip irrigation tubing is currently the most commonly used water-saving irrigation equipment. This type of tubing consists of flat, elongated, strip-shaped drippers evenly adhered to the inner wall of the tubing. A punching device precisely drills water outlets into the drip tape, aligning with the outlet grooves of the drippers. With an internal water pressure of 0.1 MPa, it provides uniform dripping and excellent water-saving performance. The dripper itself is a long, strip-shaped body with a groove on one side at the bottom. The top surface of the dripper body features a labyrinthine flow channel and an outlet groove, while the bottom surface has an inlet connected to the outlet groove via the labyrinthine flow channel. This type of embedded drip irrigation tubing is manufactured using equipment including a feeding machine, screening machine, conveyor rail, delivery machine, main unit, sizing device, cooling device, traction punching machine, wire laying machine, winding machine, and control cabinet.

[0003] The currently used screening machine for producing inlaid patch drip irrigation pipes includes a frame, main motor, main reducer, auxiliary motor, auxiliary reducer, inclined base, cylinder, chassis, rotating track ring, power control box, air source control box, air pipes, and compressed air source. The power control box, air source control box, main motor, and auxiliary motor are fixedly mounted on the bottom of the frame. The main motor and main reducer are connected for transmission, and the auxiliary motor and auxiliary reducer are also connected for transmission. The power control box is electrically connected to the main motor and auxiliary motor via wires, and the air source control box is connected to the compressed air source. The cylinder is cylindrical and fixedly mounted on the upper part of the frame. A discharge port is located on the side wall of the bottom of the cylinder, and horizontal blowing holes are evenly distributed along the circumference of the bottom side wall of the cylinder. These horizontal blowing holes are connected to the side wall of the cylinder. The air blowing pipe is connected to the air source control box via an air pipe; a sloping base is fixedly installed in the middle of the frame, and the drive shaft of the main reducer passes through the center hole of the sloping base and is connected and fixed to the mounting plate. The base is fixedly connected to the mounting plate by bolts, so that the angle between the base and the horizontal plane is 15 degrees; the rotating track ring is horizontally set at the bottom of the inner cavity of the cylinder, and the base is located in the cavity of the rotating track ring. The highest point on the circumference of the base is flush with the upper plate surface of the rotating track ring; the bottom of the rotating track ring is mounted on the frame through a bearing seat, and a gear ring is fixedly installed at the bottom of the rotating track ring. The gear ring meshes with the gear on the output shaft of the auxiliary reducer, thereby driving the rotating track ring to rotate. The rotation direction of the rotating track ring and the base is... The same applies; the outer circumference of the rotating track ring is provided with an annular screening track groove, which is adapted to the patch-type drippers. The flat blowing hole on the side wall of the cylinder is adapted to the screening track groove on the rotating track ring, so as to blow out the patch-type drippers with incorrect placement from the screening track groove, leaving only the patch-type drippers with the labyrinth flow channel facing upward and the sliding groove on the side of the dripper body locked on the inner side wall of the screening track groove; a pressure ring is fixedly provided on the inner wall of the cylinder, which is located above the screening track groove of the rotating track ring. The thickness of the pressure ring is 0.5-0.6 times the width of the screening track groove, so that the pressure ring can stably place the qualified patch-type drippers in the screening track groove, and allow the unqualified patch-type drippers to escape from between the pressure ring and the screening track groove. The nozzles are blown out through the gaps; a guide plate is fixedly provided at the discharge port of the cylinder, and the free end of the guide plate is inserted into the screening track groove of the rotating track ring, so that the patch nozzles in the screening track groove pass through the discharge port along the guide plate and enter the output track groove, and are finally output to the conveying track to enter the next process; during operation, the centrifugal force generated by the rotation of the chassis throws the patch nozzles on the chassis into the screening track groove of the rotating track ring when the chassis is flush with the rotating track ring. Patch nozzles that are not placed in the correct position are blown out of the screening track groove, while patch nozzles that are placed in the correct position remain in the screening track groove. Driven by the rotation of the rotating track ring itself, they move towards the guide plate and finally enter the next process through the discharge port.

[0004] The current screening machine for producing embedded drip irrigation pipes has the following shortcomings: since there is only one screening track groove on the rotating track ring, which has to serve both the screening and storage functions of the embedded drippers, the number of embedded drippers that can be stored is relatively small and cannot meet the needs of production lines with a production speed of more than 300 per minute; if the length of the conveyor track is increased, the production line will be too long, the floor space will be large, and the manufacturing cost of the production equipment will be high.

[0044] The special cylindrical body of this embedded patch-type dripper dual-track screening machine is characterized by: it being composed of an upper ring body 41 and a lower ring body 42, both of which are cylindrical, with the same inner diameter, and the outer diameter of the lower ring body 42 being larger than that of the upper ring body 41; an upper ring body opening 47 is provided on the circumference of the upper ring body 41; an annular outer track groove 44 is provided at the edge of the upper panel of the lower ring body 42, and a flat-blowing pipe mounting hole 43 is provided on the lower ring body 42 between the outer wall of the upper ring body 41 and the outer track groove 44; and a mounting hole 43 for the flat-blowing pipe is provided on the inner wall of the lower ring body 42. A flat blowing hole 40 is adapted to hole 43; an upper blowing pipe mounting hole 48 is provided on the peripheral side wall of the lower ring body 42; an upper blowing oblique hole 46 is provided at the bottom of the cavity of the outer track groove 44, which communicates with the upper blowing pipe mounting hole 48; a guide groove 49 is provided on the upper plate of the lower ring body 42 at the bottom of the upper ring body opening 47 of the upper ring body 41, and the guide groove 49 is connected to the first end of the outer track groove 44; a conveying track mounting groove 45 is provided on the outer side of the upper plate of the lower ring body 42 at the upper ring body opening 47 of the upper ring body 41, and the end of the outer track groove 44 is connected to the track groove of the conveying track fixed on the conveying track mounting groove 45.

[0045] The upper ring 41 and lower ring 42 are fixed as a whole and are manufactured from a single cylindrical body. The distance between the outer wall of the lower ring 42 and the outer wall of the upper ring 41 should be sufficient to meet the requirements of the outer track groove 44 and the flat blow pipe mounting hole 43.

[0046] The embedded dripper dual-track screening machine includes a frame 1, a power control box 2, an air source control box 3, a cylinder 4, a chassis 6, a rotating track ring 7, a pressure ring 8, a main motor 9, a main reducer 10, an auxiliary motor 11, an auxiliary reducer 12, an inclined base 15, an air pipe, and a compressed air source.

[0047] The bottom of the frame 1 is respectively fixed with a main motor 9 and an auxiliary motor 11. The main motor 9 is connected to the main reducer 10 for transmission, and the auxiliary motor 11 is connected to the auxiliary reducer 12 for transmission. The power control box 2 is electrically connected to the main motor 9 and the auxiliary motor 11 through wires. The air source control box 3 is connected to the compressed air source.

[0048] An inclined base 15 is fixedly provided in the middle of the upper panel of the frame 1. The drive shaft of the main reducer 10 passes through the center hole of the inclined base 15 and is connected and fixed to the mounting plate 16. The chassis 6 is connected and fixed to the mounting plate 16 by bolts. The chassis 6 is driven to rotate by the main motor 9.

[0049] The frame 1 has a cylindrical body 4 horizontally fixed on its upper plate by a bracket. The bottom of the rotating track ring 7 is mounted on the bracket by a bearing seat 13. The rotating track ring 7 is horizontally positioned at the bottom of the cavity of the cylindrical body 4. The outer circumference of the upper plate of the rotating track ring 7 is provided with an inner track groove 71. The width of the inner track groove 71 is adapted to the width of the patch-type drip head, and the depth of the inner track groove 71 is adapted to the thickness of the patch-type drip head. The base 6 is located inside the cavity of the rotating track ring 7, and the highest point on the outer edge of the base 6 is flush with the upper plate surface of the rotating track ring 7. The bottom of the rotating track ring 7 is fixed with a gear ring 14, which meshes with the gear on the output shaft of the auxiliary reducer 12 for transmission. The rotating track ring 7 is driven to rotate by the auxiliary motor 11.

[0050] The features are as follows: the cylindrical body 4 is composed of an upper ring body 41 and a lower ring body 42, both of which are cylindrical. The inner diameters of the upper ring body 41 and the lower ring body 42 are the same, and the outer diameter of the lower ring body 42 is larger than that of the upper ring body 41. An upper ring body opening 47 is provided on the circumference of the upper ring body 41. An annular outer track groove 44 is provided at the edge of the upper panel of the lower ring body 42. A flat blowing pipe mounting hole 43 is provided on the lower ring body 42 between the outer wall of the upper ring body 41 and the outer track groove 44. A flat blowing pipe mounting hole 43 is provided on the inner wall of the lower ring body 42, which is adapted to the flat blowing pipe mounting hole 43. Blow hole 40; the lower ring body 42 is provided with an upper blow pipe mounting hole 48 on its peripheral side wall; the bottom of the cavity of the outer track groove 44 is provided with an upper blow oblique hole 46 that communicates with the upper blow pipe mounting hole 48; the upper ring body 42 at the bottom of the upper ring body opening 47 of the upper ring body 41 is provided with a guide groove 49, which is connected to the first end of the outer track groove 44; the outer side of the upper panel of the lower ring body 42 at the upper ring body opening 47 of the upper ring body 41 is provided with a conveying track mounting groove 45, and the end of the outer track groove 44 is connected to the track groove of the conveying track fixed on the conveying track mounting groove 45.

[0051] A pressure ring 8 is fixedly provided on the inner wall of the upper ring body 41. A pressure ring opening 81 is provided on the circumference of the pressure ring 8. The pressure ring opening 81 is adapted to the upper ring body opening 47 of the upper ring body 41.

[0052] The flat blowing hole 40 on the inner wall of the lower ring 42 corresponds to the inner track groove 71 of the rotating track ring 7. The outer end of the flat blowing hole 40 is connected to the flat blowing pipe 17 set in the flat blowing pipe mounting hole 43. The thickness of the pressure ring 8 is less than the width of the inner track groove 71. The gap between the lower edge of the pressure ring 8 and the upper plate surface of the rotating track ring 7 is adapted to the thickness of the patch-type drip head. The compressed gas in the flat blowing pipe 17 is blown through the flat blowing hole 40 to the patch-type drip head in the inner track groove 71. The patch-type drip head that is in a qualified position remains stationary due to the blocking effect of the boss on the inner side of the inner track groove 71. The patch-type drip head that is not in a qualified position is blown out from the gap between the lower edge of the pressure ring 8 and the upper plate surface of the rotating track ring 7, thereby achieving the purpose of screening.

[0053] A guide plate 5 is fixedly installed on the inner wall of the upper ring body 41 at the opening 47. The guide plate 5 is composed of a plate body 51 and a baffle 52. The middle part of the plate body 51 is provided with a horizontally arranged bolt hole 54. The bolt passes through the bolt hole 54 on the plate body 51 and is connected and fixed to the upper ring body 41, thereby fixing the guide plate 5 to the inner wall of the upper ring body 41. A baffle 52 is fixedly installed on one side of the bottom of the plate body 51 along the length direction of the plate body 51. The bottom of the baffle 52 is placed on the bottom plate of the cavity of the guide groove 49 of the lower ring body 42. The inner end of the baffle 52 is... The plate 51 is inserted into the inner track groove 71 of the rotating track ring 7; the outer end of the plate 51 is provided with a down-blowing pipe mounting hole and a down-blowing inclined hole 53. The down-blowing pipe 19 is fixedly installed in the down-blowing pipe mounting hole, and the down-blowing inclined hole 53 is connected to the down-blowing pipe mounting hole; after the patch-type drip head in the inner track groove 71 of the rotating track ring 7 touches the baffle 52, it disengages from the inner track groove 71 and moves along the baffle 52. The compressed gas in the down-blowing pipe 19 is ejected from the down-blowing inclined hole 53 and blown onto the upper plate surface of the patch-type drip head, causing it to move forward and enter the outer track groove 44.

[0054] The upper blowing pipe mounting hole 48 on the peripheral side wall of the lower ring body 42 is connected and fixed to the upper blowing pipe 18. The top of the outer track groove 44 on the lower ring body 42 is covered with a cover plate. The width of the outer track groove 44 is adapted to the width of the patch-type drip head, and the depth of the outer track groove 44 is adapted to the thickness of the patch-type drip head. The compressed gas in the upper blowing pipe 18 is ejected from the upper blowing inclined hole 46 and blown towards the lower plate surface of the patch-type drip head, so that the patch-type drip head moves forward in the cavity of the outer track groove 44.

[0055] The flat blowing pipe 17, the upper blowing pipe 18, and the lower blowing pipe 19 are respectively connected to the air source control box 3 through air pipes.

[0056] The chassis 6 has an angle of 15 degrees with the horizontal plane, and the chassis 6 and the rotating track ring 7 rotate in the same direction.

[0057] The bottom surface of the cavity of the guide groove 49 and the bottom surface of the cavity of the outer track groove 44 are located in the same plane.

[0058] The cover plate is a glass plate so that the placement of the patch-type drip head inside the outer track groove 44 can be seen.

[0059] The upper ring body 41 and the lower ring body 42 are fixed as a whole.

[0060] The upper panel of the chassis 6 has an annular inclined surface 61 around its perimeter. The highest point on the outer edge of the annular inclined surface 61 is flush with the upper plate surface of the rotating track ring 7. This allows the patch-type drippers placed on the chassis 6 to slide from the highest point on the outer edge of the annular inclined surface 61 onto the upper plate surface of the rotating track ring 7 under the action of centrifugal force. Then, under the action of centrifugal force of the rotating track ring 7, they slide into the inner track groove 71 on the outer side of the rotating track ring 7. Since the chassis 6 is installed at an angle, only the highest point on the outer edge of the chassis 6 is flush with the upper plate surface of the rotating track ring 7. Other positions on the outer edge of the chassis 6 are lower than the upper plate surface of the rotating track ring 7. Therefore, patch-type drippers that are not placed in the inner track groove 71 of the rotating track ring 7 will be blown out and fall back onto the chassis 6.

[0061] The power control box 2 and the gas source control box 3 are respectively fixedly installed on the bottom side wall of the frame 1.

[0062] Multiple flat blowing holes 40 are arranged at intervals along the inner track groove 71 of the rotating track ring 7, and multiple upward blowing oblique holes 46 are arranged along the outer track groove 44, so as to achieve the purpose of screening and conveying.

[0063] When using this invention to screen the patch-type drippers, the corresponding switches on the power control box 2 and the gas source control box 3 are activated respectively; the chassis 6 and the rotating track ring 7 rotate in the same direction. The patch-type drippers placed on the chassis 6 move to the periphery under the action of centrifugal force. Since the chassis 6 is installed at an incline, the patch-type drippers located at the highest point of the outer edge of the annular inclined surface 61 will slide onto the upper plate surface of the rotating track ring 7, and then slide into the inner track groove 71 on the outer side of the rotating track ring 7 under the action of centrifugal force. As the rotating track ring 7 rotates, when the patch-type drippers run to the flat blowing hole 40, they are screened by compressed gas, so that the patch-type drippers that are in a qualified position continue to remain in the inner track groove 71 and remain stationary; when the patch-type drippers run to the position of the guide plate 5, they hit the baffle. After step 52, the nozzle detaches from the inner track groove 71 and moves along the baffle 52. Compressed gas in the down-blowing pipe 19 is ejected from the down-blowing oblique hole 53 and blown onto the upper plate surface of the patch-type dripper, causing it to move forward. Since the guide groove 49 is connected to the first end of the outer track groove 44, the patch-type dripper enters the outer track groove 44. Since the bottom of the cavity of the outer track groove 44 is provided with an up-blowing oblique hole 46, compressed gas in the up-blowing pipe 18 is ejected from the up-blowing oblique hole 46 and blown onto the lower plate surface of the patch-type dripper. Since the cover plate is fixedly set on the top of the outer track groove 44, the patch-type dripper can only move forward within the cavity of the outer track groove 44. Since the end of the outer track groove 44 is connected to the track groove of the conveying track fixed on the conveying track mounting groove 45, the patch-type dripper is finally sent to the next process through the conveying track.
