AI Technical Summary
现有回收装置中，将滴灌带从捡拾机构分离并输送的机构结构复杂、故障率较高，且输送效率较低；同时，滴灌带被带起的秸秆、杂草等杂物与滴灌带混合，若分离输送不及时，容易造成滴灌带缠绕堆积，影响后续回收
[0008]与现有技术相比，本申请具有以下有益效果：第一，因为绕带器的上方表面光滑、与捡拾弹齿一一对应地挂住滴灌带，拨带器的胶皮转动至绕带器时压紧在绕带器上并将滴灌带拨离，所以能够将滴灌带从捡拾机构上可靠地分离，有利于降低故障率。第二，因为喂入机构的主动喂入辊与被动喂入辊通过相同大小的齿轮一和齿轮二啮合而同步转动，被动喂入辊向下旋转夹住滴灌带，所以滴灌带被顺畅夹送到集带箱中，分离输送结构简单，有利于降低故障率、提高输送效率。第三，因为胶皮靠近外侧开设缝隙并夹住绕带器两侧，所以能够更可靠地将缠绕在绕带器上的滴灌带拨入喂入机构。第四，因为喂入机构设置随动辊和输送带，所以能够将滴灌带向集带箱深处远距离输送，有利于提高集带箱的装满度。第五，因为被动喂入辊上设置凸出的花纹，所以能够增大摩擦力，有利于更可靠地向后方输送滴灌带。

Abstract
Description
Technical Field
[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to a tape feeding and conveying mechanism for a drip irrigation tape recycling machine. Background Technology
[0002] Drip irrigation tape has water-saving advantages and is widely used in water-scarce and arid regions of central and western China. While drip irrigation tape is a disposable material, it can be recycled. After harvesting a crop, farmers often need to collect the drip irrigation tape laid in the field to reduce soil damage from residual plastic and to reuse the tape for production. After the drip irrigation tape is picked up and lifted from the bottom up by a picking mechanism, it needs to be separated from the picking mechanism and transported to a collection box. Existing recycling devices have complex structures, high failure rates, and low transport efficiency in the mechanisms that separate and transport the drip irrigation tape from the picking mechanism. Furthermore, the drip irrigation tape is often mixed with straw, weeds, and other debris carried up by the tape; if separation and transport are not timely, the tape can easily become tangled and piled up, affecting subsequent recycling. Therefore, a simple, reliable tape-picking and feeding mechanism is needed to smoothly separate the drip irrigation tape from the picking mechanism and transport it. Summary of the Invention
[0003] To address the aforementioned problems, this invention provides a tape-pulling and feeding mechanism for a drip irrigation tape recycling machine, which can pull the drip irrigation tape hanging on the tape winder away and smoothly transport it to the tape collection box through the feeding mechanism. The separation and conveying structure is simple and reliable.
[0004] This application provides a tape feeding and feeding mechanism for a drip irrigation tape recycling machine, including a tape winder, a tape puller, and a feeding mechanism. The upper surface of the wrapper is smooth and is used to catch the drip irrigation tape being picked up and lifted. The drip irrigation tape is wound and caught as the wrapper rotates. The tape puller is located above the wrapper and includes a rotating shaft, a rubber fixing seat, and a rubber sheet. The rotating shaft is rotatably connected to the frame, the rubber fixing seat is fixedly connected to the rotating shaft, and the rubber sheet is fixedly connected to the rubber fixing seat. The rubber sheet corresponds one-to-one with the wrapper. When the rubber sheet rotates to the lower position, it presses against the wrapper, pulling the drip irrigation tape hanging on the wrapper forward. The feeding mechanism includes an active feeding roller and a passive feeding roller, which are rotatably connected to the frame. One end of the active feeding roller and one end of the passive feeding roller are respectively provided with gear one and gear two of the same size. Gear one and gear two mesh, so that the active feeding roller and the passive feeding roller rotate synchronously in opposite directions, clamping the pulled-away drip irrigation tape and conveying it backward.
[0005] In one embodiment, a slit is provided near the outer side of the rubber sheet. When the rubber sheet rotates to the position of the winding device, the slit clamps the two sides of the winding device, thereby drawing the drip tape wound on the winding device into the feeding mechanism.
[0006] In one embodiment, the feeding mechanism is further provided with a follower roller and a conveyor belt. The conveyor belt wraps around the active feeding roller and the follower roller, and the passive feeding roller presses against the conveyor belt above the active feeding roller, thereby conveying the drip irrigation tape to the rear over a long distance to achieve the purpose of conveying the drip irrigation tape to the depth of the collection box.
[0007] In one embodiment, the passive feed roller is provided with raised patterns to increase the friction of the passive feed roller and better convey the drip irrigation tape backward.
[0008] Compared with existing technologies, this application has the following advantages: First, because the upper surface of the wrapper is smooth and hooks the drip irrigation tape one-to-one with the pick-up teeth, when the rubber of the puller rotates to the wrapper, it presses against the wrapper and pulls the drip irrigation tape away, thus reliably separating the drip irrigation tape from the pick-up mechanism, which helps reduce the failure rate. Second, because the active feed roller and the passive feed roller of the feeding mechanism rotate synchronously through the meshing of gear one and gear two of the same size, and the passive feed roller rotates downward to clamp the drip irrigation tape, the drip irrigation tape is smoothly clamped into the collection box. The separation and conveying structure is simple, which helps reduce the failure rate and improve the conveying efficiency. Third, because the rubber has a slit near the outside and clamps both sides of the wrapper, the drip irrigation tape wound on the wrapper can be more reliably pulled into the feeding mechanism. Fourth, because the feeding mechanism is equipped with a follower roller and a conveyor belt, the drip irrigation tape can be conveyed far into the collection box, which helps improve the filling rate of the collection box. Fifth, because the passive feed roller has raised patterns, it can increase friction, which is beneficial for more reliable delivery of drip irrigation tape to the rear. Attached Figure Description

[0011] The invention will now be further described with reference to the accompanying drawings.
[0012] Example 1: As Figure 1 , Figure 2 , Figure 3 As shown, the tape feeding and feeding mechanism for the drip irrigation tape recovery machine includes a tape winder (5), a tape winder (6), and a feeding mechanism (7). Wheels (2) are installed on both sides of the frame (1) near the rear. The wheels (2) are adjustable up and down, providing support during transport and controlling the height of the frame (1) during operation. The tape winder (5) is fixed in front of the automatic pickup mechanism. The upper surface of the tape winder (5) is smooth, with one end extending towards the automatic pickup mechanism and beyond the pickup teeth, ensuring a certain distance between this end and the rear crossbeam. The tape winder (5) is positioned between the up and down movement paths of the pickup teeth and corresponds one-to-one with the pickup teeth, used to catch the drip irrigation tape (15) lifted by the pickup teeth. The tape winder (6) consists of a rotating shaft (61), a rubber fixing seat (62), and a rubber sheet (63). Figure 4 As shown, the tape puller (6) is set on the frame (1) near the tape winder (5) and the feeding mechanism (7). The rotating shaft (61) is rotatably connected to the frame (1) above the tape winder (5), the rubber fixing seat (62) is fixedly connected to the rotating shaft (61), and the rubber (63) is fixedly connected to the rubber fixing seat (62). The number of rubber fixing seats (62) corresponds one-to-one with the tape winder (5). When the rubber (63) moves to the bottom, it can be tightly scraped on the tape winder (5) to scrape the drip tape (15) hanging on the tape winder (5) forward. The feeding mechanism (7) consists of an active feeding roller (71) and a passive feeding roller (72). The active feeding roller (71) and the passive feeding roller (72) are rotatably connected to the frame (1), adjacent to the winding device (5) at the rear and adjacent to the collection box at the front. One end of the active feeding roller (71) and the passive feeding roller (72) are respectively meshed by gear one (75) and gear two (76) of the same size, so that the active feeding roller (71) and the passive feeding roller (72) rotate synchronously in opposite directions. The passive feeding roller (72) rotates downward to clamp the drip irrigation tape (15), so that the drip irrigation tape (15) falls directly into or is transported to the collection box at the front by the conveyor belt.
[0013] Example 2: Compared with Example 1, in this example, the rubber (63) on the puller (6) has a slit near the outside and corresponds to the winding device (5); when the rubber (63) rotates to the position of the winding device (5), the slit tightly clamps the two sides of the winding device (5) and pulls the drip irrigation tape (15) wrapped on the winding device (5) into the feeding mechanism (7).
[0014] Example 3: Compared with Example 1, the feeding mechanism (7) in this example is further provided with a follower roller (73) and a conveyor belt (74). The conveyor belt (74) is wrapped around the active feeding roller (71) and the follower roller (73), and the passive feeding roller (72) presses on the conveyor belt (74) above the active feeding roller (71). This feeding mechanism (7) can transport the drip irrigation tape (15) conveyed between the passive feeding roller (72) and the conveyor belt (74) to a long distance to meet the purpose of transporting the drip irrigation tape (15) to the depth of the collection box.
[0015] Example 4: Compared with Example 1, the passive feeding roller (72) of the feeding mechanism (7) in this example is provided with raised patterns to increase the friction of the passive feeding roller (72) and can better transport the drip irrigation tape (15) pushed over by the rubber (63) to the rear.
[0016] When the tape-pulling and feeding mechanism described in Example 1 is working, the picked-up and lifted drip irrigation tape (15) is hung on the tape winder (5). When the rubber (63) of the tape puller (6) rotates to the bottom, it presses against the tape winder (5), pulling the drip irrigation tape (15) hanging on the tape winder (5) forward. Then the passive feeding roller (72) of the feeding mechanism (7) rotates downward to clamp the drip irrigation tape (15), so that the drip irrigation tape (15) falls directly into or is transported to the collection box in front by the conveyor belt, thus completing the separation and transportation of the drip irrigation tape.
