Description

A grafting machine with a 45-degree cutting station

technical field

The invention relates to a fruit and vegetable grafting machine with sticking method, in particular to a grafting machine with a 45-degree cutting station.

Background technique

With the continuous improvement of agricultural production automation technology and the rapid increase in the demand for vegetable grafting, people's requirements for vegetable grafting machinery are also getting higher and higher. In the current rotary sticking method grafting equipment, the two configured seedling clamping arms all swing back and forth within a range of 180 degrees, wherein the scion and rootstock are extracted at the 180 degree seedling picking station (the operator picks the seedlings at the two seedling picking stations respectively). The station supplies the scion and rootstock to the equipment), the 90-degree cutting station cuts the scion and the rootstock separately, and the 0-degree laminating and grafting station glues the cut scion and rootstock to complete the grafting operation (another clamping and bonding The mechanism glues the scion and the rootstock together and then transports them out of the grafting machine); due to the large swing range of the rotating arm (180-degree reciprocating swing), the distance between the two seedling picking stations is far, and two arms are required for single-person operation. For seedlings (rootstock and scion), thus the work intensity is relatively large, and the width of the complete machine is relatively large, which is unfavorable for the miniaturization of the grafting machine.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned background technology and provide a grafting machine that can realize the layout of 45-degree cutting stations. The characteristics of low labor intensity of personnel.

The technical scheme adopted in the present invention is as follows.

A grafting machine with a 45-degree cutting station, including a seedling picking mechanism and a cutting mechanism arranged on a frame, in the seedling picking mechanism, two seedling clamping arms that respectively clamp a scion and a rootstock are separated by a certain distance and are symmetrical Arranged on a vertical plane, the two cutting arms in the cutting mechanism that cut the clamped scion and rootstock respectively are spaced at a certain distance and symmetrically arranged on the aforementioned vertical plane; it is characterized in that:

The midpoint of the connecting line between the rotation axes of the two seedling clamping arms is the joint grafting station between the scion and the rootstock after cutting; When the respective clamping arms rotate 45 degrees in the opposite direction, they are the cutting stations for cutting the clamped scion and rootstock; The seedling claws of the arm grip the scion and the seedling picking stations of the rootstock respectively.

The distance between the two seedling clamping arms is the sum of the lengths of the two seedling clamping arms; Distance between gripping points.

The axes of rotation in the two cutting mechanisms are offset by a certain angle from the center line of the cutting arm, and the cutting arms in the two cutting mechanisms are reciprocatingly swinging within 180 degrees and the starting and ending positions of the rotation are opposite , so that the carried cutting tools reciprocate alternately from the highest point to the lowest point to avoid interference between the two cutting mechanisms.

Among the two cutting mechanisms, one cutting mechanism is used to cut off a cotyledon and growth point on the upper end of the rootstock, and the other cutting mechanism is used to cut off the root system of the scion; the cutting arm is driven up and down by the rotating cylinder to complete the cutting action.

The working principle of the present invention is: when the present invention started to work, two seedling clamping rotating arms clamped the scion and clamped the stock at the seedling taking station respectively, and stopped after rotating 45 degrees (arriving at the cutting station), and the two cutting The cutting arms of the mechanism are respectively driven by the rotating cylinder to cut the scion and rootstock clamped by the two seedling-clamping arms, and then the two seedling-clamping arms continue to rotate 45 degrees to reach the laminating and grafting station. The station combines the rootstock and scion after cutting to complete the grafting of the whole seedling; a grafting cycle ends.

Repeat the above process, and the grafting operation reciprocates.

The beneficial effects of the present invention are: the grafting machine provided by the present invention has 45 degree cutting stations (that is, the two seedling clamping arms of the grafting machine can reach the seedling taking station and rotate 45 degrees forward and backward respectively from the cutting station. Fitting grafting station), the rotation range of the seedling clamping arm is reduced from 180 degrees to 90 degrees, and the structure of the whole machine becomes more compact, which is conducive to comfortable operation by one person. At the same time, the arrangement method of the cutting mechanism can effectively avoid the interference between the two cutting mechanisms.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following examples.

As shown in Figure 7, the rotating shaft 1-3 in the described seedling picking mechanism 1 is rotatably positioned on the frame (horizontal frame) by the flange bushing 1-9 and the bearing 1-2, and the seedling clamping arm 1 -1 is composed of a transition connecting plate 1-4, a biaxial cylinder 1-5, a connecting block 1-6, a pneumatic finger 1-7 and a seedling picking claw 1-7a. The base body of the biaxial cylinder 1-5 is fixedly connected with the upper end of the rotating shaft through the transition connecting plate, and the pneumatic fingers are fixedly connected with the end of the piston rod of the biaxial cylinder through the connecting block; the seedling-picking jaws are used to grip the seedlings to be grafted; The lower end 1-3a of the rotating shaft passes through the frame and is fixedly connected with the stepper motor shaft (the stepper motor drives the seedling-taking rotating arm 1-47 to rotate back and forth in 90 degree range, the stepper motor is omitted among the figures).

As shown in Figure 1-4: two seedling clamping pivoting arms are spaced at a certain distance and are symmetrical to a vertical plane S (represented with a dotted line in Fig. 2). The midpoint C of the line P (that is, the starting line of the angle) between the two seedling-clamping pivoting arms rotation axes is the fitting grafting station of the scion after cutting and the rootstock. The length of the connecting line is the sum of the lengths of the two seedling-clamping arms (the length of the seedling-clamping arm is the distance between the rotation axis of the seedling-clamping arm and the gripping point of the seedling claw on the seedling-clamping arm).

It can be seen in the figure that the seedling claw 1-7a on one of the seedling clamping arms extracts the rootstock 1-7a at the seedling picking station A-1 (position after the seedling clamping arm rotates 90 degrees clockwise from the starting line of the angle). 3a, and cutting the rootstock clamped by the seedling claws of the seedling clamping arm by the cutting mechanism at the cutting station B-1 (position after the seedling clamping arm rotates 45 degrees clockwise from the angle starting line); The seedling claw 1-7a on another seedling clamping arm extracts the scion 1-3b at the seedling picking station A-2 (position after the seedling clamping arm rotates 90 degrees counterclockwise from the angle starting line), and The cutting station B-2 (the position after the seedling clamping arm rotates 45 degrees counterclockwise from the angle starting line) is cut by the cutting mechanism on the scion clamped by the seedling clamping arm and the seedling claw.

As shown in Figure 5 and Figure 6, the cutting mechanism 2 includes a cutting blade 2-1, a blade mounting column 2-1a, a moving adjustment arm 2-2, a cutting arm 2-3, a rotating cylinder 2-4, Bracket 2-5 and screw 2-6a. The moving regulating arm 2-2 is fixed to the cutting arm by a screw 2-6a (the screw passes through the long hole 2-2c and is tightened on the cutting arm), which is used to adjust the position of the cutting blade relative to the axis of the rotating cylinder axis (i.e. The radius of rotation of the cutting blade); the front end of the mobile regulating arm 2-2 has a round hole 2-2b, a screw hole 2-2a, and the axis of the screw hole 2-2a is perpendicular to the round hole 2-2b; the cutting blade is fixed On the blade installation column 2-1a, the blade installation column 2-1a is inserted in the circular hole 2-2b and can be slid and adjusted along the axis of the circular hole, and the screw can be screwed into the screw hole to realize the fastening of the blade installation column; The cutting arm 2-3 is fixed on the shaft end of the rotary cylinder 2-2, and driven by the rotary cylinder, the cutting blade can reciprocate up and down within a range of 180 degrees. In order to avoid interference between the two cutting mechanisms, the rotation axes of the two cutting mechanisms are offset from the center line of the cutting arm by a certain angle, and the cutting arms of the two cutting mechanisms reciprocate within a range of 180 degrees Swing and turn the starting and ending positions opposite, so that the cutting tool carried alternately reciprocates from the highest point to the lowest point (that is, while the cutting tool of one cutting mechanism moves from the highest point to the lowest point, the cutting tool of the other cutting mechanism moves from the highest point to the lowest point. The tool moves from the lowest point to the highest point.

It can be seen in the figure that the centerline of the cutting arm 2-3 forms an included angle of 45 degrees with the rotary axis of the rotary cylinder 2-4 and the sliding direction of the moving regulating arm 2-2 (as shown in FIG. 5 ); Said rotary cylinder 2-4 is installed on the support 2-5.

When the present invention started to work, the two clamping arms first clamped the rootstock 1-3a and the scion 1-3b respectively at 90 degree stations A-1 and A-2, and the two clamping arms were driven by the stepping motor. The rotating arm carries the rootstock and the scion and rotates 45 degrees respectively, and then reaches the cutting stations B-1 and B-2 to stop; then the two cutting rotating arms 2-4 swing under the drive of their respective rotary cylinders to complete the cutting of the rootstock and the scion respectively. Then the two seedling clamping arms continue to rotate 45 degrees respectively to reach the fitting grafting station C and the rootstock and the scion after cutting are attached together at this station (in addition, the rootstock and the scion are bonded together by the clamping adhesion mechanism. The cutting parts are fitted together, and then conveyed out of the grafting machine), the combination of the rootstock and the scion is completed, and a grafting cycle ends.

The above cycle is repeated, and the grafting operation is carried out continuously.

It should be noted that the present invention only improves the cutting mechanism and the seedling picking mechanism in the grafting machine, and other mechanisms in the grafting machine remain unchanged (also all omitted in the figure).
