Description

Technical Field

[0001] The utility model belongs to the field of strawberry planting equipment, and particularly relates to a strawberry membrane breaking and hole punching device. Background Art

[0002] Greenhouse strawberry cultivation is a common technique, known for its excellent thermal insulation properties and popular popularity, allowing people to enjoy out-of-season strawberries at any time. Typically, greenhouse strawberry cultivation utilizes a bamboo and steel frame, covered with one or more layers of insulating plastic film. After strawberry seedlings emerge, they often cannot break through the film on their own, resulting in a low emergence rate. This necessitates the use of a hole-piercing device to break through the film.

[0003] Existing strawberry film breaking and hole punching equipment uses a downward pressure punching cylinder to cut the film around the strawberry seedlings. However, during operation, it is often difficult to remove the discarded film in one go, requiring bending over and performing the operation twice, which is time-consuming, labor-intensive, and inefficient. Therefore, we proposed a strawberry film breaking and hole punching device to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing strawberry film breaking and hole punching equipment cuts off the ground film at the strawberry seedlings by pressing down the hole punching cylinder, and the waste ground film cannot be taken out at one time during operation, and the user needs to bend down to perform the operation twice, which is time-consuming, labor-intensive and inefficient.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0006] A strawberry membrane-breaking and puncturing device comprises a puncturing tube, an insertion rod fixedly mounted on the upper end of the puncturing tube, and a hand-held portion arranged on the upper part of the insertion rod. The lower end of the puncturing tube is serrated, and a fixing strip with a rectangular cross-section is fixedly mounted on the top of the inner wall of the puncturing tube. A puncture needle is movably mounted inside the puncture tube, and a limiting tube is fixedly mounted on the puncture needle, and the limiting tube is movably sleeved on the fixing strip. A plurality of arc-shaped elastic strips are fixedly mounted on the lower part of the puncture needle, and a driving mechanism for driving the puncture needle to move up and down is provided on the puncture tube.

[0007] The handle further defines a sleeve, a handle, and a locking bolt. The sleeve is mounted on the insertion rod, the handle is fixedly mounted on the upper end of the sleeve, and the sleeve is provided with a threaded groove, into which the locking bolt is threaded. This structural design allows the insertion rod inserted in the sleeve to be locked by the locking bolt, facilitating adjustment of the length of the acupuncture device.

[0008] Furthermore, the sleeve is provided with a strip-shaped through-hole near the handle. With this structural design, the strip-shaped through-hole can maintain air circulation inside and outside the sleeve, making it easy to adjust the position of the insertion rod in the sleeve.

[0009] It is further defined that the driving mechanism includes a fixed block, a first movable rack, a grounding plate, a compression spring and a gear, the fixed block is fixedly mounted on the acupuncture tube, the first movable rack is movably inserted into the fixed block, a limiting convex strip is fixedly mounted on the first movable rack, a groove adapted to the limiting convex strip is provided on the fixed block, the grounding plate is fixedly mounted on the lower end of the first movable rack, the compression spring is sleeved on the first movable rack, and the compression spring is located between the fixed block and the grounding plate, a positioning block is fixedly mounted on the upper part of the first movable rack, when the positioning block conflicts with the upper end of the fixed block, the grounding plate is located at the lower side of the acupuncture tube, an installation slot is provided on the acupuncture tube, the gear is rotatably mounted in the installation slot, the gear is meshed with the first movable rack, and a second movable rack meshed with the gear is fixedly mounted on the puncture needle. With this structural design, the compression spring and the grounding plate cooperate with the first movable rack, the gear and the second movable rack to drive the puncture needle to move up and down, so that the puncture needle can penetrate the ground film when the acupuncture tube breaks the film and punches acupuncture points. At the end of breaking the film and punching acupuncture points, the puncture needle cooperates with the arc-shaped elastic strip to lift the cut ground film away from the ground.

[0010] The utility model adopting the above technical solution has the following advantages:

[0011] The utility model drives the puncture needle up and down through the driving mechanism. When the acupuncture tube cuts the ground film, the puncture needle can penetrate the ground film downward, and then cooperates with the arc-shaped elastic strip to bring the cut ground film upward away from the ground. The discarded ground film can be taken out at one time, which saves time and effort and improves the efficiency of film breaking and acupuncture. BRIEF DESCRIPTION OF THE DRAWINGS

A puncture needle 5 is movably installed inside the acupuncture tube 1, and a limiting tube 51 is fixedly installed on the puncture needle 5. The limiting tube 51 is movably sleeved on the fixing strip 4. The fixing strip 4 has a limiting effect on the limiting tube 51, so that the puncture needle 5 can move vertically up and down. A plurality of arc-shaped elastic strips 52 are fixedly installed on the lower part of the puncture needle 5, and a driving mechanism for driving the puncture needle 5 to move up and down is provided on the acupuncture tube 1.

[0029] The hand-held part 3 includes a sleeve 31, a handle 32 and a locking bolt 33. The sleeve 31 is sleeved on the insertion rod 2, and the handle 32 is fixedly installed on the upper end of the sleeve 31. A threaded groove is provided on the sleeve 31, and the locking bolt 33 is threadedly connected in the threaded groove. A strip-shaped through-hole 34 is provided on the sleeve 31 near the handle 32.

[0030] The driving mechanism includes a fixed block 6, a first movable rack 61, a grounding plate 62, a compression spring 63 and a gear 64. The fixed block 6 is fixedly mounted on the puncture tube 1, the first movable rack 61 is movably plugged into the fixed block 6, a limited convex strip 611 is fixedly mounted on the first movable rack 61, a groove adapted to the limited convex strip 611 is provided on the fixed block 6, the grounding plate 62 is fixedly mounted on the lower end of the first movable rack 61, the compression spring 63 is sleeved on the first movable rack 61, and the compression spring 63 is located between the fixed block 6 and the grounding plate 62. Between the ground plate 62, a positioning block 612 is fixedly installed on the upper part of the first movable rack 61. When the positioning block 612 conflicts with the upper end of the fixed block 6, the ground plate 62 is located at the lower side of the acupuncture tube 1. When the membrane rupture acupuncture device is used, the ground plate 62 will contact the ground before the acupuncture tube 1, thereby driving the puncture needle 5 to move. A mounting groove is provided on the acupuncture tube 1, and a gear 64 is rotatably installed in the mounting groove. The gear 64 is engaged with the first movable rack 61, and the puncture needle 5 is fixedly installed with a second movable rack 53 engaged with the gear 64.

[0031] The method of using the utility model is as follows:

[0032] When in use, the position of the insertion rod 2 in the sleeve 31 is adjusted, and the insertion rod 2 is locked by the locking bolt 33, thereby adjusting the overall length of the membrane rupture and acupuncture device;

[0033] When the acupuncture tube 1 is controlled to break the membrane and drill holes downward by the handle 32, the ground plate 62 will contact the ground before the acupuncture tube 1. When the force is applied downward, the compression spring 63 is squeezed, and the first movable rack 61 moves upward, driving the gear 64 to rotate, driving the second movable rack 53 and the puncture needle 5 downward to penetrate the ground film;

[0034] After the acupuncture tube 1 cuts off the ground film and is lifted off the ground by the hand-held part 3, the force under the ground plate 62 is released, and the compression spring 63 recovers its deformation, prompting the first movable rack 61, the gear 64 and the second movable rack 53 to reset. At this time, the puncture needle 5 cooperates with the arc-shaped elastic strip 52 to lift the cut ground film upward, and the discarded ground film can be taken out at one time, saving time and effort and improving the efficiency of film breaking and acupuncture.
