Description

Technical Field

[0001] The utility model relates to the technical field of grafting machines, in particular to a turning and unloading device for grafting machines. Background Art

[0002] Grafting seedlings can effectively overcome obstacles such as soil environmental deterioration and serious soil-borne diseases caused by continuous cropping, and is also a good way to increase production. The application of mechanical grafting technology can solve the problems of low efficiency, high labor intensity and low survival rate of grafted seedlings in manual grafting, providing a strong guarantee for the widespread promotion of grafting seedling technology.

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0029] During the grafting process, the plants are placed horizontally, and the adjacent plants are too close, causing interference between branches and leaves, resulting in unreasonable incision docking. Therefore, it is necessary to separate the adjacent plants as much as possible. After the grafted plants are stored, they need to be as close as possible to improve space utilization. For this purpose, it is necessary to design a flipping mechanism and a plant spacing adjustment mechanism.

[0030] See also Figure 1-Figure 4 The grafting machine uses a flipping and unloading device, including a positioning plate 2 fixedly mounted on the grafting frame 1. As one of the options, corresponding positioning plates 2 are respectively fixedly mounted on the left and right sides of the upper part of the grafting frame 1, and corresponding first slide rails 21 are respectively fixedly mounted on each positioning plate 2. Each first slide rail 21 is respectively slidably connected with a corresponding rotating cylinder 22, and the two rotating cylinders 22 are commonly connected to a connecting plate 23. Specifically, the two ends of the connecting plate 23 are respectively connected to the output ends of the corresponding rotating cylinders 22, and the two rotating cylinders 22 act synchronously, and the two rotating cylinders 22 jointly support the connecting plate 23 and drive the connecting plate 23 to perform flipping motion.

[0031] A plurality of first clamping units 24 are transversely fixed to the bottom of the connecting plate 23 for clamping the plants. The first clamping units 24 include longitudinally arranged extension heads 241. The purpose of such design is to more reasonably receive the grafted plants and to transform the transversely arranged planting beads into longitudinally arranged planting beads after flipping.

[0032] As one of the options, the first clamping unit 24 can be a pneumatic clamp (pneumatic claw), and the two clamps (extension heads) for clamping the plant can have a circular or arc-shaped avoidance opening for accommodating the plant trunk after closing without affecting its clamping of the plant trunk.

[0033] Before the plant is turned over, the position of the grafted plant needs to be transferred to a place with sufficient space. In this embodiment, a second slide rail 31 is also provided on the grafting frame 1. A slider 32 is slidably provided on the second slide rail 31. A cylinder is fixed on the slider 32. A plate 33 is connected to the output end of the cylinder. A plurality of second clamping units 34 are fixed on the plate 33. The second clamping units 34 can also have the same structure as the first clamping units 24, and can be pneumatic clamps. The spacing between adjacent second clamping units 34 is the same as the spacing between adjacent first clamping units 24. As one option, the clamping heads of the second clamping units 34 are arranged longitudinally.

[0034] After the second clamping unit 34 transfers the grafted plant to the position of the first clamping unit 24 (the position can be identified by a sensor and the action stops at the corresponding position), the second clamping unit 34 and the plant clamped on the second clamping unit 34 are lowered to the first clamping unit 24 through the cylinder, and then the grafted plant is clamped by the first clamping unit 24, and then the rotary cylinder 22 is rotated 90 degrees to change the horizontal arrangement of the grafted plant into a longitudinal arrangement, and then the position of the rotary cylinder is transferred by the driving mechanism, specifically to the third clamping unit 41 arranged on the unloading rack.

[0035] As for the driving mechanism for driving the rotating cylinder 22 to slide, there can be many forms, such as being pushed by the cylinder, such as being through a matching structure of a screw and a nut (the screw is driven by a motor, and the nut is arranged on the rotating cylinder), being through a matching structure of a gear and a rack (the gear is driven by a motor and rotatably connected to the grafting frame, and the rack is arranged on the rotating cylinder), etc.

[0036] The unloading frame is provided with a third slide rail 42, a second slider 43 slidably connected to the third slide rail 42, a third cylinder 44 arranged on the second slider 43, a second plate 45 connected to the output end of the third cylinder 44 and driven by it to make longitudinal movement, a plurality of third clamping units 41 arranged on the second plate 45 and an unloading platform 46.

[0037] The second slider 43 is driven by a corresponding driving mechanism to slide laterally on the third slide rail 42. The driving mechanism can refer to existing designs, such as being pushed by a cylinder, by a matching structure of a screw nut, by a matching structure of a gear rack, etc.

[0038] After the first clamping unit 24 moves with the grafted plant to the third clamping unit 41, the third clamping unit 41 descends and after descending to the position of the grafted plant, the first third clamping unit 41 clamps the corresponding plant, and then the second plate 45 moves laterally to move the second third clamping unit 41 to the second grafted plant and clamp the plant, and the cycle continues. After each third clamping unit 41 clamps the corresponding plant, the corresponding first clamping unit 24 is released.

[0039] In this embodiment, the spacing between adjacent third clamping units 41 is smaller than the spacing between adjacent first clamping units 24. Therefore, after the clamping action of the third clamping units 41, the spacing between adjacent grafted plants is shortened to facilitate subsequent storage.

[0040] In order to facilitate the unloading of grafted plants after boxing and the transportation of empty boxes, in this embodiment, a conveyor belt is provided on the unloading platform 46. The driving method of the conveyor belt can refer to the existing design, so as to complete a grafting operation.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
