Description

Technical Field

[0001] This utility model relates to a seedling release device, belonging to the field of agricultural equipment technology. Background Technology

[0002] When planting crops such as cotton and garlic, it is necessary to cover them with agricultural film. After the crop seedlings grow, the film needs to be opened to allow the seedlings to grow without affecting their growth. Currently, there is no relevant machinery, so the seedlings can only be released manually. This is labor-intensive, requires high density, has extremely high labor costs, cannot be released in a timely manner, and is inefficient. Utility Model Content

[0003] This utility model provides a seedling release device that solves the problems of high labor intensity, high density, extremely high labor costs, inability to release seedlings in a timely manner, and low efficiency of manual seedling release.

[0004] This utility model relates to a seedling release device, including a walking mechanism and a film opening mechanism. The walking mechanism is provided with a transmission mechanism that drives the film opening mechanism to rotate and move forward.

[0005] The film-opening mechanism includes a film-opening wheel, on which multiple film openers are evenly installed, which can facilitate film opening at fixed intervals.

[0006] The film opener includes a pair of film opening claws with a gap between them. The outer end of the film opening claws is angled with the outer side wall of the film opening wheel to facilitate film opening and improve the film opening effect.

[0007] The distance between the two film-opening claws gradually increases from the end fixed to the film-opening wheel to the other end, thus improving the film-opening effect.

[0008] Two film-opening claws are fixed to one end of the film-opening wheel and connected to each other to form a U-shaped structure. The two film-opening claws have outward bends at the ends away from the film wheel to facilitate manufacturing and installation.

[0009] The two film-opening claws are connected to each other and fixed to the film-opening wheel by a fixing bolt. The film-opening wheel is provided with a mounting hole for the fixing bolt to pass through, which is convenient for installation. The mounting hole is an arc-shaped strip hole, which can adjust the circumferential position of the film opener.

[0010] The film-opening wheel includes a film-opening ring plate, and multiple support plates are evenly fixed on the inner side of the film-opening ring plate. A support sleeve is fixed on the inner end of the support plate. A driven rotating shaft is provided inside the support sleeve. A locking bolt is provided on the support sleeve. The driven rotating shaft is connected to the transmission mechanism.

[0011] The walking mechanism includes a drive shaft with walking wheels fixed at both ends. The drive shaft is rotatably connected to a connecting rod, which in turn is rotatably connected to a driven shaft. The drive shaft and the driven shaft are connected and driven by a transmission mechanism. The walking wheels and the film-opening wheel are driven by differential speed. A pusher is rotatably mounted on the drive shaft. The differential speed transmission between the walking wheels and the film-opening wheel enables the film-opening wheel to slide forward while rotating, thus improving the film-opening effect.

[0012] The transmission mechanism includes a driving sprocket fixed on the driving shaft, a driven sprocket connected to the driving sprocket via a chain, and the driven sprocket fixed on the driven shaft. The transmission structure is simple and practical.

[0013] The diameter of the traveling wheel is larger than that of the opening wheel. Both ends of the connecting rod and the connection end between the pusher and the drive shaft are equipped with a rotating sleeve. The rotating sleeve on one end of the connecting rod and the pusher is fitted onto the drive shaft, and the rotating sleeve on the other end of the connecting rod is fitted onto the driven shaft. A limiting sleeve is provided on the outside of the rotating sleeve, and an adjusting bolt is provided on the limiting sleeve. The limiting sleeve can prevent the connecting rod and the pusher from sliding along the axial direction of the drive shaft.

[0014] This utility model has the following beneficial effects:

[0015] The walking mechanism moves on the ground, driving the film-opening mechanism to rotate and move forward, thereby opening the film at the seedling placement point, improving seedling placement efficiency, saving manpower, reducing labor intensity, and saving labor costs.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example 1, as Figures 1 to 4As shown, this utility model is a seedling release device, including a walking mechanism and a film opening mechanism. The walking mechanism is provided with a transmission mechanism that drives the film opening mechanism to rotate and move forward.

[0023] In use, the walking mechanism is placed on the ground, and the film-opening mechanism is positioned opposite the crop seedlings. The walking mechanism moves, and through the transmission mechanism, it drives the film-opening mechanism to rotate and slide forward, thereby opening the film and releasing the seedlings.

[0024] Example 2, based on Example 1, includes a film-opening mechanism comprising a film-opening wheel 7, with multiple film-opening devices evenly mounted on the outer circumference of the film-opening wheel 7. The film-opening devices can be installed according to the spacing between seedlings in the same row.

[0025] The film opener includes a pair of film opening claws 14, with a gap between the two film opening claws 14, and an angle between the outer end of the film opening claw 14 and the outer side wall of the film opening wheel 7.

[0026] The distance between the two opening claws 14 gradually increases from the fixed end with the opening wheel 7 to the other end.

[0027] Two opening claws 14 are fixed to one end of the opening wheel 7 and connected to each other to form a U-shaped structure. The two opening claws 14 have an outward bend at the end away from the opening wheel 7.

[0028] Two opening claws 14 are connected to each other and one end is fixed to the opening wheel 7 by a fixing bolt 10. The opening wheel 7 is provided with a mounting hole for the fixing bolt 10 to pass through. The mounting hole is an arc-shaped strip hole.

[0029] The film-opening wheel 7 includes a film-opening ring plate, on the inner side of which multiple support plates 13 are evenly fixed. A support sleeve 15 is fixed to the inner end of each support plate 13. A driven rotating shaft 11 is located inside the support sleeve 15, and a locking bolt is mounted on the support sleeve 15. The driven rotating shaft 11 is connected to a transmission mechanism. Before operation, the locking bolts can be loosened according to the spacing of the crop seedlings, and then the positions of the support sleeves 15 on the driven rotating shaft 11 can be adjusted to axially adjust the film-opening wheel and meet different row spacing requirements.

[0030] The walking mechanism includes a drive shaft 3, with walking wheels 4 fixed at both ends of the drive shaft 3. The drive shaft 3 is rotatably connected to a connecting rod 5, which is rotatably connected to a driven shaft 11. The drive shaft 3 and the driven shaft 11 are connected and driven by a transmission mechanism. The walking wheels 4 and the film-opening wheel 7 are driven by differential speed. A pusher 8 is rotatably mounted on the drive shaft 3.

[0031] The transmission mechanism includes a drive sprocket 1 fixed on the drive shaft 3. The drive sprocket 1 is connected to a driven sprocket 9 via a chain 6. The transmission ratio between the drive sprocket 1 and the driven sprocket 9 is 1:1. The driven sprocket 9 is fixed on the driven shaft 11. The transmission mechanism is not limited to this structure; synchronous belts and pulleys, belts and pulleys, and other transmission structures can also be used.

[0032] The diameter of the traveling wheel 4 is larger than that of the film-opening wheel 7. Both ends of the connecting rod 5 and the connection point between the pusher 8 and the drive shaft 3 are equipped with rotating sleeves 2. One end of the connecting rod 5 and the rotating sleeve 2 on the pusher 8 are fitted onto the drive shaft 3, while the other end of the connecting rod 5 is fitted onto the driven shaft 11. A limiting sleeve 12 is provided on the outer side of the rotating sleeve 2, and an adjusting bolt is provided on the limiting sleeve 12. The pusher 8 can rotate around the drive shaft 3, suitable for operators of different heights. During operation, the pusher 8 is pushed to move the seedling machine to the work site, with the film-opening wheel 7 positioned above the rows of seedlings. Then, the pusher 8 is pushed forward, causing the traveling wheel 4 and the film-opening wheel 7 to rotate. The rotation of the drive shaft 3 can drive the driven shaft 11 to rotate through the transmission mechanism. When the film opener contacts the film, it hooks onto it. Simultaneously, the film-opening wheel 7 slides forward, causing the film opener to tear the film. As the film opener continues to rotate, it disengages from the film, ultimately releasing the seedlings.
