Description

Technical Field

[0001] The utility model relates to the technical field of grafting machines, in particular to an automatic cutting mechanism of a grafting machine. 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.

[0003] When grafting two plants, the grafting machine needs to cut out the grafting interface first. The existing method usually clamps the plant with a clamping mechanism, and then directly cuts off the excess part with a blade to cut out the grafting interface. Because the excess part of the plant cut off usually includes the root with soil, this part has a certain weight. If this part is not fixed, it is easy to cause the incision to be not smooth during the incision, affecting the grafting effect. For this reason, the applicant has made improvements.

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0022] See also Figure 1-Figure 3 The automatic cutting mechanism of the grafting machine includes a grafting frame 1, on which a series of components related to the grafting operation are arranged so that the grafting operation can be completed on the grafting frame 1.

[0023] Corresponding manipulators are respectively arranged on the left and right sides of the grafting frame 1. The manipulator on the left is used to grab one of the plants to the grafting frame 1; the manipulator on the right is used to grab another plant to the grafting frame 1.

[0024] In this embodiment, a first slide rail 2 is provided on the grafting frame 1. As one of the options, two first slide rails 2 are provided, which are respectively distributed on both sides of the top of the grafting frame 1. A first slide plate 3 and a second slide plate 4 arranged left and right are slidably provided on the first slide rail 2. A plurality of first clamping units 31 are fixed on the first slide plate 3, and a plurality of second clamping units 41 are fixed on the second slide plate 4. The first clamping unit 31 and the second clamping unit 41 can be components with the same structure, and both include a clamping head. As one of the options, the first clamping unit 31 and the second clamping unit 41 can both be pneumatic grippers (pneumatic jaws). The two grippers for clamping the plant can have a circular or arc-shaped avoidance opening for accommodating the trunk of the plant after closing, and it does not affect the clamping of the trunk of the plant.

[0025] Among them, the first clamping units 31 are evenly and equidistantly arranged on the top surface of the first slide plate 2, the manipulator located on the left side grabs one of the plants (multiple) at the same time and transfers it to the first clamping unit 31, and clamps the plant through the first clamping unit 31; the manipulator located on the right side grabs another plant (multiple) at the same time and transfers it to the second clamping unit 41, and clamps the plant through the second clamping unit 41.

[0026] When the first clamping unit 31 and the second clamping unit 41 clamp corresponding plants respectively, the two plants are arranged on the left and right sides of the grafting frame 1 respectively.

[0027] Then, the redundant parts of the two plants are cut off by the cutting unit arranged on the grafting frame 1, so that the incisions of the two plants are opposite to each other, so that the two incisions can fit each other after being abutted.

[0028] The cutting unit includes a first cylinder 51 fixed on the grafting frame 1 and a cutting blade 52 which is connected to the first cylinder 51 for longitudinal movement. In this embodiment, a group of cutting units are respectively arranged at the left and right ends of the grafting frame 1, and each group of cutting units has a plurality of cutting blades 52 which are evenly and equidistantly distributed. The position of each cutting blade 52 corresponds to the position of the corresponding clamping unit. As one of the options, each group of cutting units is driven by the same first cylinder 51, and the output end of the first cylinder 51 is connected to a bracket 53. Each cutting blade 52 is fixedly arranged on the bracket 53, so that all related cutting blades 52 can be driven by the first cylinder 51 to move longitudinally synchronously.

[0029] As a further optimized design, a third clamping unit 54 is provided on the bracket 53. The third clamping unit 54 can also have the same structure as the first clamping unit 31 and the second clamping unit 41, and can be a pneumatic clamp. The horizontal height of the part of the clamping head of the third clamping unit 54 that clamps the plant is equal to or slightly higher than the horizontal height of the cutting blade 52. It is also driven by the first cylinder 51 to move longitudinally. When the cutting blade 52 cuts the corresponding plant trunk, the sixth clamping unit 44 provides support and / or clamping for the excess part of the plant trunk, so that the incision position when the cutting blade 52 cuts is more accurate, and the incision is easier to graft.

[0030] In the initial state, the horizontal height position of the cutting blade 52 is lower than the horizontal height position of the plant clamped by the first clamping unit 31 and the second clamping unit 41. Therefore, after the first clamping unit 31 and the second clamping unit 41 clamp the corresponding plant, the first cylinder 51 is started to push the cutting blade 52 upward to cut off the excess parts of the plant.

[0031] In this embodiment, the cutting blades are evenly and equidistantly distributed on the bracket, and the spacing between two adjacent cutting blades is equal to the spacing between two adjacent first clamping units, the spacing between two adjacent second clamping units, and the spacing between two adjacent third clamping units.

[0032] In this embodiment, the cutting blade is arranged obliquely on the top of the bracket, such as Figure 2 In one arrangement, the first clamping unit and the third clamping unit, the second clamping unit and the third clamping unit are parallel to each other, while the cutting blade is not parallel to each clamping unit. The extension lines of the two bodies intersect, and the corresponding angle can be 30-60 degrees.

[0033] After the cutting operation is completed, the incision docking operation is performed. In this embodiment, the first slide 2 and the second slide 3 move toward each other to dock the two incisions. There are many forms of power sources required for the movement of the first slide 222 and the second slide 3, such as respectively setting corresponding cylinders to drive the two to move toward each other along the first slide rail; or respectively setting corresponding lead screw and nut structures to drive the two to move toward each other along the first slide rail, the lead screw is arranged on the first slide rail, and the nut is arranged under the first slide and the second slide, the lead screw is directly driven by the motor, or is connected to the motor through a transmission structure such as a worm gear, a helical gear, etc.; or driven by a linear cylinder or the like.

[0034] In this embodiment, a wrapping assembly is further provided in the middle of the grafting frame 1, which is longitudinally movably arranged in the middle of the grafting frame 1, and is used to wrap the two grafted plants into finished seedlings through the grafting clamp.

[0035] The wrapping assembly is arranged below the position where the incisions of the two plants are connected. The specific structure of the wrapping assembly can refer to the existing design. It at least has a driving mechanism for transporting the grafting clip from bottom to top to the incision connection position. The specific detailed structure can refer to the public patent documents CN115088494B, CN117643232A, etc.

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.
