Description

Technical Field

[0001] The invention relates to the technical field of mechanical grafting seedling cultivation, and in particular to a seedling gathering positioning and cutting mechanism. Background Art

[0002] With the development of grafting technology, the mechanization level of automatic seedling supply of grafting machines has been greatly improved, and great progress has been made in directional seedling supply. The grafting machine can automatically cut the stems of the seedlings, which greatly improves the efficiency of cutting the stems of the seedlings and further improves the efficiency of subsequent seedling grafting.

[0003] In actual grafting production, it is necessary to cut the stems of the seedlings and form an incision with a certain angle, and ensure the standardization of the incision angle, so as to improve the incision docking and fitting effect of the grafted seedlings, and then ensure the healing survival rate of the grafted seedlings.

[0004] However, in the current grafting machine, during the cutting process of the scion seedling, the upright stem of the seedling is usually first single-point positioned or limited, and then the cutting operation is carried out. When this cutting method is implemented, it is difficult for the stem of the seedling to maintain a standard upright state, and the cutting quality of the seedling stem depends entirely on the upright state of the seedling itself. If the uprightness is poor, the angle of the incision after the seedling stem is cut will deviate too much, and during the operation, the incision angle of each cutting is difficult to maintain consistent, which seriously affects the quality of the incision docking and the survival rate of the grafted seedlings.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] See also Figure 1 to Figure 2 The present embodiment provides a seedling gathering positioning and cutting mechanism, comprising a seedling gathering part 2, a cutting part 3 and a clamping claw 4; the seedling gathering part 2 comprises a clamping mechanism, a first seedling gathering block 24 and a second seedling gathering block 25, the first seedling gathering block 24 and the second seedling gathering block 25 are arranged opposite to each other and separately installed on the clamping mechanism, and opposite sides of the first seedling gathering block 24 and the second seedling gathering block 25 are respectively provided with a seedling gathering opening 28, and the seedling gathering openings 28 on the opposite sides are relatively assembled or separated under the drive of the clamping mechanism; the seedling gathering opening 28 of the seedling gathering part 2 corresponds to the clamping end of the clamping claw 4 up and down, and is used to clamp the upper and lower points of the stem of the seedling 5 respectively, and the cutting part 3 is used to cut the part between the upper and lower points of the stem of the seedling 5.

[0030] The gripping jaw 4 is provided with a gripping mechanism 22 for gripping the seedlings 5 ​​so that the grafting jaw 4 is in a state of being lifted and lowered, and the gripping jaw 4 is provided with a gripping mechanism 23 for gripping the seedlings 5.

[0031] Furthermore, the clamping mechanism in this embodiment includes a double-headed cylinder 21 and a first seedling gathering arm 22 and a second seedling gathering arm 23 which are relatively arranged on both sides of the double-headed cylinder 21; one end of the first seedling gathering arm 22 and the second seedling gathering arm 23 are respectively connected to the two telescopic ends of the double-headed cylinder 21, and the other ends of the first seedling gathering arm 22 and the second seedling gathering arm 23 are respectively connected to the first seedling gathering block 24 and the second seedling gathering block 25.

[0032] For details, see Figure 3 The double-headed cylinder 21 can adopt a double-piston rod cylinder known in the art, and a telescopic end is provided on each side of the double-piston rod cylinder. When the two telescopic ends retract toward each other relative to the double-headed cylinder 21, the corresponding first seedling gathering block 24 and the second seedling gathering block 25 can be driven to approach each other through the first seedling gathering arm 22 and the second seedling gathering arm 23 respectively, until the seedling gathering opening 28 set on the opposite side of the first seedling gathering block 24 and the second seedling gathering block 25 are spliced ​​into one, so as to position and clamp the seedling stems of the seedlings 5; conversely, when the two telescopic ends on the double-headed cylinder 21 are extended in opposite directions, the first seedling gathering block 24 and the second seedling gathering block 25 are separated.

[0033] Furthermore, in this embodiment, opposite sides of the first seedling gathering block 24 and the second seedling gathering block 25 are provided with seedling gathering pieces 26 which are arranged oppositely and staggered up and down; a "V"-shaped guide opening 27 is provided on the seedling gathering piece 26, and a seedling gathering opening 28 is provided at the corner of the "V"-shaped guide opening 27.

[0034] For details, see Figure 4By designing the seedling gathering pieces 26 on the opposite sides of the first seedling gathering block 24 and the second seedling gathering block 25 to be relatively and staggered in an upper and lower manner, in the process of the first seedling gathering block 24 and the second seedling gathering block 25 approaching each other, the seedling gathering pieces 26 on the opposite sides will also approach each other without touching each other; at the same time, by providing a "V"-shaped guiding opening 27 on the seedling gathering pieces 26 and providing a seedling gathering opening 28 at the corner of the "V"-shaped guiding opening 27, in the process of the seedling gathering pieces 26 on the opposite sides approaching each other, the "V"-shaped guiding opening 27 will gradually guide the seedling stems of the seedlings 5 ​​to move toward their corners until the seedling stems of the seedlings 5 ​​fall into the seedling gathering opening 28, thereby completing the guidance, positioning and clamping of the seedling stems of the seedlings 5 ​​in sequence, and in this process, the seedling stems of the seedlings 5 ​​will not be damaged.

[0035] Furthermore, in the present embodiment, the seedling-gathering pieces 26 include multiple layers; the multiple layers of seedling-gathering pieces 26 are alternately arranged on opposite sides of the first seedling-gathering block 24 and the second seedling-gathering block 25, and can be embedded with each other as a whole.

[0036] For details, see Figure 4 The opposite sides of the first seedling gathering block 24 and the second seedling gathering block 25 are respectively provided with three layers of seedling gathering pieces 26 in sequence from top to bottom along the vertical direction, and the three layers of seedling gathering pieces 26 on the first seedling gathering block 24 and the three layers of seedling gathering pieces 26 on the second seedling gathering block 25 are arranged alternately and relatively, so that they can be embedded with each other as a whole; after the seedling gathering pieces 26 on the opposite sides are embedded as a whole, the seedling gathering openings 28 on the seedling gathering pieces 26 on the opposite sides of each layer are just matched together to clamp and fix the seedling stems of the seedlings 5; in addition, in the actual working process, the number of layers of the seedling gathering pieces 26 can be adaptively increased or decreased according to the length of the seedling stems of the seedlings 5 ​​to ensure the reliability of clamping and fixing the seedling stems of the seedlings 5.

[0037] Furthermore, in the present embodiment, the seedling gathering opening 28 on the seedling gathering piece 26 is in an arc shape; when the seedling gathering pieces 26 on the opposite sides are embedded as one body, the seedling gathering openings 28 on the opposite sides are combined to form a circle or an ellipse.

[0038] Specifically, since the stems of the seedlings 5 ​​are usually elliptical in structure, the seedling gathering opening 28 is designed to be arc-shaped, so that the seedling gathering openings 28 on the opposite sides can be combined into a circle or an ellipse, and thus when the stems of the seedlings 5 ​​are clamped and fixed, the stems of the seedlings 5 ​​will not be damaged.

[0039] Furthermore, in this embodiment, first elastic pads 29 are respectively provided on opposite sides of the first seedling gathering block 24 and the second seedling gathering block 25 .

[0040] For details, see Figure 4The first elastic pad 29 can be made of sponge, and the first elastic pad 29 is arranged on the lower side of the seedling gathering piece 26. The thickness of the first elastic pad 29 is slightly greater than the distance from the first seedling gathering block 24 or the second seedling gathering block 25 to the corresponding seedling gathering opening 28, so that the seedling gathering openings 28 on the opposite sides are spliced, and when the seedling stems of the seedlings 5 ​​are clamped and fixed, the two first elastic pads 29 arranged on the opposite sides of the first seedling gathering block 24 and the second seedling gathering block 25 will elastically wrap the lower part of the seedling stems of the seedlings 5 ​​and achieve a further fixing effect.

[0041] Furthermore, the present embodiment also includes a pushing portion 1; the seedling gathering portion 2 is installed on the pushing portion 1, and the direction of relative movement of the first seedling gathering block 24 and the second seedling gathering block 25 is perpendicular to the pushing direction of the pushing portion 1; the cutting portion 3 is installed on the seedling gathering portion 2, and the cutting direction of the cutting portion 3 is perpendicular to the pushing direction of the pushing portion 1; the clamping claw 4 and the seedling gathering portion 2 are arranged relative to each other along the pushing direction of the pushing portion 1, and the clamping portion of the clamping claw 4 is located on the upper side of the seedling gathering mouth 28 of the seedling gathering portion 2.

[0042] For details, see Figure 1 In actual work, first, the clamping part of the clamping claw 4 clamps the upper part of the stem of the seedling 5, and the clamping claw 4 is driven by the on-site mechanical arm to move horizontally, so that the clamping claw 4 supports the seedling 5 and moves to the top of the cutting station; then, the pushing part 1 pushes the seedling gathering part 2 and the cutting part 3 installed thereon to move along the pushing direction, so that the seedling gathering mouth 28 of the seedling gathering part 2 is located below the cutting station; then, the seedling gathering part 2 positions and clamps the lower part of the stem of the seedling 5; finally, the cutting part 3 cuts the part between the upper and lower points clamped on the stem of the seedling 5.

[0043] Furthermore, in this embodiment, the pushing part 1 includes a base 11, a first pushing cylinder 12, a guide rod 13 and a slide 14; the first pushing cylinder 12 is installed on the base 11, and the telescopic end of the first pushing cylinder 12 is connected to one side of the slide 14; the slide 14 is slidably connected to the guide rod 13, and the seedling gathering part 2 is installed on the slide 14.

[0044] For details, see Figure 5 The base 11 is a groove-shaped structure. The first pushing cylinder 12 is fixed on the groove wall on one side of the base 11. The push rod of the first pushing cylinder 12 is parallel to two parallel guide rods 13 arranged in the groove body of the base 11. The telescopic end of the front side of the push rod of the first pushing cylinder 12 is connected to one side of the slide 14. The slide 14 is slidably connected to the two guide rods 13. A connecting plate 15 for installing the double-headed cylinder 21 in the clamping mechanism is provided on the slide 14.

[0045] Furthermore, in this embodiment, the cutting part 3 includes a connecting seat 31, a second pushing cylinder 32 and a cutting tool 33; the connecting seat 31 is installed on the seedling gathering part 2; the second pushing cylinder 32 is installed on the connecting seat 31, and the cutting tool 33 is installed at the telescopic end of the second pushing cylinder 32, and the cutting tool 33 extends between the clamping part of the clamping claw 4 and the seedling gathering mouth 28 of the seedling gathering part 2.

[0046] For details, see Figure 1 The connecting seat 31 is connected to the side wall of the double-headed cylinder 21 in the clamping mechanism, so that the cutting part 3 can move together with the seedling gathering part 2; the cutting tool 33 can be a rigid blade, the cutting edge of the cutting tool 33 is set at the front end and corresponds to the stem of the seedling 5, and the rear end of the cutting tool 33 is connected to the telescopic end of the second pushing cylinder 32. Therefore, after the inclination angle of the cutting tool 33 is set, the seedling stem of the seedling 5 can be cut by the cutting edge of the front end of the cutting tool 33 through the ejection action of the telescopic end of the second pushing cylinder 32, and a standard incision can be directly formed.

[0047] Furthermore, in this embodiment, the clamping claw 4 includes a pneumatic finger composed of a third push cylinder 41 and two clamping claws 42. The clamping portion is located at the clamping ends of the two clamping claws 42. The inner side of the clamping portion is provided with a second elastic pad 43. Figure 2 .

[0048] Specifically, for the pneumatic fingers, the middle parts of the two clamping jaws 42 are rotatably mounted on the third pushing cylinder 41, and the telescopic ends of the third pushing cylinder 41 are respectively hinged to one end of the two clamping jaws 42, and the other ends of the two clamping jaws 42 can clamp or open simultaneously with the telescopic action of the telescopic end of the third pushing cylinder 41; in addition, by arranging a second elastic pad 43 on the inner side of the clamping part, this can effectively prevent the seedling stems of the seedlings 5 ​​from being damaged due to excessive clamping force.

[0049] Finally, it should be noted that 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 they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
