Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to an automatic picking 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 it for production. However, the laying environment for drip irrigation tape is complex: some tape is shallowly buried in the soil or laid in closely spaced rows of crops, often accompanied by mulching, with a layer of mulch and topsoil covering the tape. Although drip irrigation tape has a certain degree of flexibility, in these complex environments, existing recycling devices frequently break when directly picking up the tape, leading to missed pickups and low efficiency. Furthermore, the straw, weeds, and other debris carried up by the tape mix with the tape, resulting in a high impurity content in the recycled material. Existing pickup and separation structures are also complex and prone to failure. Therefore, an automated pickup mechanism is needed that can vertically pick up the drip irrigation tape from bottom to top and separate it from the soil and debris during the lifting process. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides an automatic picking mechanism for a drip irrigation tape recycling machine, which can pick up and lift the drip irrigation tape from bottom to top, and allow soil and debris to fall off naturally during the lifting process, thereby achieving the separation of the drip irrigation tape from the soil and debris.

[0004] This application provides an automatic pickup mechanism for a drip irrigation tape recycling machine, mounted on the machine's frame. The automatic pickup mechanism includes at least two sets of sprockets, each set consisting of an upper sprocket, a lower sprocket, and a chain. The upper sprocket is fixed above the frame, and the lower sprocket is fixed below the frame. The upper and lower sprockets are connected by the chain, forming a transmission structure that moves along a circular trajectory. The automatic pickup mechanism also includes a rear crossbeam, which is rotatably connected to the chain and parallel to the ground, moving along the circular trajectory with the chain. Furthermore, the automatic pickup mechanism includes several tooth fixing seats and pickup teeth corresponding to the number of tooth fixing seats. The tooth fixing seats are fixed to the rear crossbeam, one end of each pickup tooth is fixed to a tooth fixing seat, and the other end of the pickup tooth is hook-shaped with an acute angle at the front to scoop up the drip irrigation tape.

[0005] In one embodiment, at least one set of sprockets has two lower sprockets, and the distance between the two lower sprockets can be adjusted to change the width range of the picking tooth picking up the drip irrigation tape below, thereby compensating for the problem that the required picking range increases due to the left and right movement of the drip irrigation tape.

[0006] Compared with existing technologies, this application has the following beneficial effects: First, because the picking teeth move along the chain along a circular trajectory and move laterally at the lowest point, the acute angle in front of the hook scoops up the drip irrigation tape. After the drip irrigation tape enters the hook, it moves upward with the picking teeth, and the upward movement of the picking teeth is perpendicular to the ground. Therefore, soil, straw, and other debris naturally fall off during the lifting process, which can separate the drip irrigation tape from the soil and debris, reducing the probability of tape breakage and missed detection during pickup and improving recycling efficiency. Second, because at least one set of sprockets has two lower sprockets with adjustable spacing, the distance of the picking teeth's lateral movement below can be changed. This can compensate for the problem of the increased pickup range caused by the left and right movement of the drip irrigation tape, and facilitate more effective pickup of the drip irrigation tape.

Detailed Implementation

[0009] The invention will now be further described with reference to the accompanying drawings.

[0010] Example 1: As Figure 1 , Figure 2As shown, the automatic pickup mechanism (4) for the drip irrigation tape recycling machine is fixed at the rear of the frame (1). Wheels (2) are installed on both sides of the frame (1) near the rear. These wheels (2) are adjustable up and down, providing support during transport and controlling the height of the frame (1) during operation. The automatic pickup mechanism (4) includes at least two sets of sprockets. Each set consists of an upper sprocket (42), a lower sprocket (43), and a chain (44). The upper sprocket (42) is fixed above the frame (1), and the lower sprocket (43) is fixed below the frame (1). The upper sprocket (42) and lower sprocket (43) are connected by the chain (44). The rear crossbeam (46) is rotatably connected to the two chains (44) via a chain-connected rotating device (45) and is parallel to the ground. Several pickup tooth fixing seats (48) are fixed on the rear crossbeam (46); one end of the pickup tooth fixing seat (48) is fixed on the rear crossbeam (46), and the other end is fixed with a pickup tooth (47), so that one end of the pickup tooth (47) is a certain distance away from the rear crossbeam (46). The bottom of the pickup tooth (47) is hook-shaped, and the front of the hook is an acute angle. The transmission mechanism of the automatic pickup mechanism (4) is the power source for the operation of the automatic pickup mechanism (4), which is composed of sprockets, chains, etc. Its power source can be the rear output drive shaft of the tractor, or a hydraulic motor (such as a hydraulic motor (41)).

[0011] Example 2: Compared with Example 1, in this example, the automatic picking mechanism (4) has two lower sprockets (43), the chain (44) is triangular, and the distance between the two lower sprockets (43) can be adjusted to change the width range of the picking tooth (47) picking up the drip irrigation tape (15) below, which can make up for the problem that the required picking range is larger due to the left and right movement of the drip irrigation tape (15).

[0012] When the automatic picking mechanism (4) described in Example 1 is working, the drip irrigation tape (15) is laid in the planting row in the field, partially buried in the soil, and covered with mulch and topsoil. When the picking tooth (47) of the automatic picking mechanism (4) is at its lowest point, it moves laterally and uses the acute angle in front of the hook to scoop up the lifted drip irrigation tape (15). After the drip irrigation tape (15) enters the hook, it moves upward with the picking tooth (47). Since the picking tooth (47) moves upward perpendicular to the ground, soil and straw and other debris fall off naturally, and the drip irrigation tape (15) is picked up and lifted, which facilitates subsequent winding, pulling and conveying.
