Detailed Implementation

[0054] The present invention will be further described in detail below with reference to the embodiments shown in the accompanying drawings.

[0055] The positional relationships in this article are determined as follows: Figure 1 The left and right sides are set as "left" and "right" respectively; Figure 1 The bottom and top sides are set as "bottom" and "top" respectively; vertically pointing... Figure 1 Set the paper orientation to "forward" and leave vertically. Figure 1 Set the paper orientation to "back".

[0056] The grafting process of the grafted seedling is shown in the drawing: S1 step: cut the stems of the rootstock seedling and the scion seedling respectively, discard the upper part of the rootstock seedling and discard the lower half of the scion seedling (including the substrate; the shape of the substrate taken out of the plug tray still retains the outline of the plug tray) to obtain the rootstock 0223 and the scion 0221; S2 step: align and fit the cutouts of the rootstock and the scion to form a grafted seedling; S3 step: open the clamping opening of the grafting clamp to wrap the cut-fitting part of the grafted seedling; that is, the upper clamping is completed, and the grafting is completed.

[0057] The light and simple semi-automatic solanaceous vegetable grafting machine shown in the drawing comprises an automatic upper clamping mechanism 01, a cutting and butt joint mechanism 02, and a seedling gathering mechanism 03 installed on a rack 0101.

[0058] The automatic upper clamping mechanism 01 and the cutting and butt joint mechanism 02 are arranged in the rack 0101, and the seedling gathering mechanism 03 is arranged on the upper side of a table top 0132, which is horizontally arranged on the top of the rack; the cutting and butt joint mechanism cuts the grafted seedling into a rootstock and a scion and makes them butt joint; the seedling gathering mechanism aligns the cutting part of the rootstock and the scion after butt joint through seedling gathering; the automatic upper clamping mechanism cuts a grafting clamp of a certain size from a grafting clamp strip and then opens the clamping opening of the grafting clamp to finally clamp (clamp the butt joint part of the grafted seedling).

[0059] Referring to the drawing; the clamp storage disc 0154 (prior art) is positioned on the clamp storage disc support column 0147 of the rack by the stepped shaft 0116 installed at the axial position thereof (the clamp storage disc support column and the upper clamping bottom plate support column 0145 are both vertically fixed on the bottom frame of the rack); one end of the stepped shaft penetrates the stepped shaft interface 0146 from left to right (the direction is perpendicular to the direction of the paper) Figure 3 , and is then fastened by a bolt, so as to be installed on the clamp storage disc support column; the inner disc 0111 and the outer disc 0114 are fixed as a whole by a plurality of disc connecting pieces 0112 with threads therebetween and are rotatably positioned on the stepped shaft by bearings; the clamp storage limiting piece 0113 is positioned on the outer disc by a screw connection; the clamp storage limiting piece has a clamp storage limiting piece adjusting groove 0110, so that the position of the clamp storage limiting piece on the outer disc can be adjusted, thereby facilitating the storage of the grafting clamp. The long grafting clamp strip 0153 is wound in the space between the inner disc and the outer disc of the clamp storage disc. When the grafting clamp strip is pulled by the automatic upper clamping machine, the stepped shaft and the clamp storage disc are driven to rotate, so that the grafting clamp wound on the clamp storage disc is unwound, and the rotation direction is clockwise. Figure 3 .

[0060] The automatic clamping mechanism 01 is installed on the upper clamping base plate 0102 and includes a push-clamping pneumatic finger 0128 for clamping the grafting clips in the storage tray, a push-clamping cylinder 0107 for pulling the grafting clips in the storage tray out a certain distance by pushing the pneumatic finger, a push-blade three-axis cylinder 0104 for cutting the pulled-out grafting clips by driving a utility knife blade 0119, an opening-clamping pneumatic finger 0125 for opening the grafting clips obtained by cutting, and a lifting-clamping cylinder 0121 for lifting the grafting clips upward to clamp the rootstock and scion.

[0061] The upper clamping base plate 0102 is connected to the frame by bolts inserted through the upper clamping base plate connecting holes 0130. The upper clamping base plate is provided with a clamping groove 0149 to guide the movement of the grafting clamping strip 0153. The clamping groove 0149 is formed by bolting together the clamping groove base plate 0108 and the clamping groove cover plate 0109, and is used to guide the movement of the grafting clamping strip. The extension direction of the clamping groove is the front-to-back direction. Figure 13 (It is perpendicular to the paper surface direction); the clamping base plate is bolted to the clamping adjustment groove 0131 of the upper clamping base plate. The extension direction of the clamping adjustment groove is from left to right, and the left and right positions of the clamping base plate can be adjusted through the clamping adjustment groove. Figure 13 In the process, the grafting strip moves from front to back in the groove.

[0062] Both the rear limit block 0117 and the front limit block 0120 are provided with through holes for the grafting clip to pass through, and are positioned on the upper clamp base plate by screw connection; the shape of the through hole is the same as that of the clamp groove 0149, which can limit the length of the grafting clip strip to be cut (which is the width of the grafting clip after cutting); the grafting clip strip enters the rear limit block 0117, the clamp groove and the front limit block 0120 from back to front under the pull of the push clamp pneumatic finger.

[0063] The push-clamp connector 0106 is connected to the push-clamp cylinder 0107 by screws, and the push-clamp cylinder is then fixed to the upper clamp base plate by screws; the push-clamp finger 0128 is positioned on the push-clamp connector by screws, and the pneumatic push-clamp finger drives the push-clamp finger block 0126 to clamp the grafting clamp strip passing through the clamping groove, and under the action of the push-clamp cylinder, moves the grafting clamp strip from back to front. Figure 14 The process involves advancing the grafting clip from bottom to top to the required distance (during which the grafting clip that has been cut off and is stuck in the front limit block 0120 is pushed into the clamping opening of the clamping block 0124), and then the utility knife 0119 cuts off a section from the grafting clip strip to obtain the required grafting clip 0152.

[0064] As shown in the attached diagram: the three-axis pusher cylinder 0104 is fixed on the three-axis pusher cylinder connector 0105, which is fixed to the upper clamp base plate by bolts. The three-axis pusher cylinder drives the utility blade 0119 to cut the grafting clip; the grafting clip cut from the grafting clip is used to fix the grafted seedling, which is composed of rootstock and scion; the cutting direction is from back to front (…).Figure 14 The cutter cover plate 0118 is positioned on the cutter holder 0127 by screw connection (see Figure 15 ), and the art knife blade is clamped and fixed between the cutter cover plate and the cutter holder, which is connected to the cylinder rod of the push cutter three-axis cylinder.

The cut stock and scion are respectively placed horizontally on the stock supporting seat and the scion supporting seat, and the axes of the stock and the scion are horizontal to the table top, and the extension direction of the axes is from front to back.

[0070] The medium sliding groove 0203 is connected and positioned on the table plate and the cutting butt joint bottom plate by screws, and the medium block cut by the scion seedling falls into the medium sliding groove, and then falls from the table top to the collection frame on the lower side of the machine through the corresponding upper and lower table top medium falling port 0137 and medium falling port 0237.
