Description

Technical Field

[0001] The utility model belongs to the technical field of seedling grafting, and particularly relates to an adjustable cutting device for melon seedlings. Background Art

[0002] Grafting is the main technical measure to overcome the continuous cropping obstacles of melon vegetables and achieve high yield and good quality. The common grafting method for melons is mainly the sticking method. First, it is necessary to take rootstock seedlings, and use a blade to obliquely cut off the growth point and true leaves of the rootstock from the base of one cotyledon at an angle of 40-45°, retaining the hypocotyl and the connected cotyledons; then take the scion, and obliquely cut at 40-45° 2 mm below the growth point, retaining two cotyledons and the connected hypocotyl. Immediately afterwards, closely attach the oblique cutting surfaces of the scion and the rootstock, and fix them with a flat grafting clip or a flexible sleeve.

[0003] When cutting traditional melon seedlings, most of them use a tool with a fixed stroke to move linearly to complete the cutting. When facing seedlings of different heights, due to the fixed height and stroke of the blade, the actual cutting surface is not at the same distance from the growth points of different seedlings. Too high or too low cutting surfaces will affect the healing effect and lead to unstable grafting effects.

[0004] Therefore, we propose an adjustable cutting device for melon seedlings to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem of unstable grafting effect of the cutting surface in the prior art, and propose an adjustable cutting device for melon seedlings.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An adjustable cutting device for melon seedlings, including a mounting base. One side of the mounting base is fixedly provided with a vertical slide rail. A lead screw is rotatably arranged in the slide rail. A slider located in the slide rail is threadedly sleeved on the lead screw. One side of the slider extends out of the slide rail and is fixedly connected to an inclined working plate. The side of the working plate inclined upwards is set as the working surface, and the side inclined downwards is set as the mounting surface. At both ends of the working surface of the working plate, a scion cutting blade and a rootstock cutting blade are respectively arranged, and the scion cutting blade is located directly above the rootstock cutting blade. A power module for driving the scion cutting blade and the rootstock cutting blade to rotate synchronously is fixedly installed on the mounting surface of the working plate;

[0008] It also includes a leaf pressing rod arranged on the side surface of the working plate, and a leaf pressing cylinder for driving the movement of the leaf pressing rod. The leaf pressing cylinder is fixedly installed on the mounting surface of the working plate, and one end of the leaf pressing rod is connected to the leaf pressing cylinder and the other end extends to the working surface;

[0009] It also includes a trimming pneumatic scissors disposed directly below the rootstock cutting blade, and a trimming telescopic cylinder for driving the movement of the trimming pneumatic scissors. The trimming telescopic cylinder is fixedly installed on the mounting seat.

[0010] Preferably, a lifting motor for driving the rotation of the lead screw is fixedly installed at the top of the slide rail.

[0011] Preferably, rotating seats are rotatably provided at both ends of the working surface of the working board. The rootstock cutting blade is fixedly connected to the side surface of the lower rotating seat, and the seedling cutting blade is fixedly connected to the side surface of the upper rotating seat through a connecting rod.

[0012] Preferably, the power module includes a cutting motor fixedly installed on the installation surface of the working board, and a synchronization component disposed between the two rotating seats. The cutting motor drives the rotation of one of the rotating seats.

[0013] Preferably, the synchronization component includes a synchronous pulley fixedly sleeved on the outside of the rotating seat. An auxiliary pulley is slidably provided on the working board between the two synchronous pulleys. A synchronous belt is commonly sleeved on the outside of the two synchronous pulleys and an auxiliary pulley.

[0014] In summary, the technical effects and advantages of the present utility model are as follows: For this adjustable cutting device for melon seedlings, compared with the existing devices, through the rotation of the lead screw and the cooperation of the slider working board moving up and down along the slide rail, the seedling cutting blade and the rootstock cutting blade can be adjusted up and down. The power module drives the synchronous rotation and cutting of the seedling cutting blade and the rootstock cutting blade, ensuring that the cutting surfaces of the seedlings and the rootstocks are accurately and consistently positioned, avoiding the problems of too high, too low, and inconsistent cutting surfaces when facing seedlings of different heights, and improving the grafting effect.

[0015] In addition, through the setting of the trimming pneumatic scissors and the trimming telescopic cylinder, while rotating and cutting, the scissors below the rootstock extend to cut off the hypocotyl of the rootstock and quickly retract, completing the trimming action, which is convenient for subsequent cutting.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1-3 , a tunable cutting device for melon seedlings, including a mounting base 1. A vertical slide rail 2 is fixedly provided on one side of the mounting base 1, and a lead screw 3 is rotatably provided in the slide rail 2. A slider 4 is threadedly sleeved on the lead screw 3 and is located in the slide rail 2. One side of the slider 4 extends out of the slide rail 2 and is fixedly connected to an inclined working plate 5. The side surface of the working plate 5 inclined upward is set as the working surface 5A, and the side surface inclined downward is set as the mounting surface 5B. Spikelet cutting blades 6 and rootstock cutting blades 7 are respectively arranged at both ends of the working surface 5A of the working plate 5, and the spikelet cutting blade 6 is located directly above the rootstock cutting blade 7. A power module for driving the spikelet cutting blade 6 and the rootstock cutting blade 7 to rotate synchronously is fixedly installed on the mounting surface 5B of the working plate 5.

[0024] It further includes a leaf pressing rod 8 arranged on the side surface of the working plate 5, and a leaf pressing cylinder 9 for driving the leaf pressing rod 8 to move. The leaf pressing cylinder 9 is fixedly installed on the mounting surface 5B of the working plate 5. One end of the leaf pressing rod 8 is connected to the piston end of the leaf pressing cylinder 9, and the other end extends to the working surface 5A. The leaf pressing rod 8 presses down to the petiole to prevent the leaves from affecting the cutting.

[0025] It further includes trimming pneumatic scissors 10 arranged directly below the rootstock cutting blade 7, and a trimming telescopic cylinder 11 for driving the trimming pneumatic scissors 10 to move. The trimming telescopic cylinder 11 is fixedly installed on the mounting base 1. The trimming pneumatic scissors 10 cooperate with the trimming telescopic cylinder 11 to realize the telescopic cutting function and complete trimming the rootstock hypocotyl, preparing for subsequent fixing and cutting of the rootstock hypocotyl.

[0026] Refer to Figure 5, this adjustable cutting device for melon seedlings is located at the cutting station. In the grafting process of melon seedlings, the feeding station should be set in the previous step of the cutting station. When in use, a camera facing the feeding station should be arranged to identify the growth point of the rootstock at the feeding station. After the identification is completed, the rootstock and scion seedling at the feeding station start to move towards the cutting station. At the same time, the camera sends the operation result to this cutting device. The lead screw 3 rotates and drives the slider 4 and the operation board 5 to perform fine up and down adjustment. When the rootstock and scion seedling move to the cutting station, the leaf pressing cylinder 9 drives the leaf pressing rod 8 to descend and press the petiole. The rotary cutter rotates one circle to complete the cutting. At the same time, the pneumatic scissors extend to cut off the hypocotyl of the rootstock. The leaf pressing rod 8 and the pneumatic scissors retract at the same time to complete the operation of the cutting station.

[0027] The synchronous cutting of the rootstock and scion seedling can improve efficiency. In addition, compared with the common linear cutting motion cutting, the rotary cutting method can more easily reach high speed and improve the flatness of the cutting surface.

[0028] A lifting motor 12 for driving the lead screw 3 to rotate is fixedly installed at the top of the slide rail 2. The lifting motor 12 should cooperate with the camera to achieve precise fine adjustment of the height of the cutter. The cooperation between the lead screw 3 and the slider 4 should use a ball screw to reduce friction and improve stability.

[0029] In order to facilitate the simultaneous cutting of the scion seedling and the rootstock, it is necessary to make the scion seedling cutting blade 6 and the rootstock cutting blade 7 located on the same vertical line. Therefore, rotating seats 13 are rotatably provided at both ends of the working surface 5A of the operation board 5. The rootstock cutting blade 7 is fixedly connected to the side of the lower rotating seat 13, and the scion seedling cutting blade 6 is fixedly connected to the side of the upper rotating seat 13 through a connecting rod 15.

[0030] Refer to Figure 2 、 Figure 4 , the power module includes a cutting motor 14 fixedly installed on the installation surface 5B of the operation board 5, and a synchronous component arranged between the two rotating seats 13. The cutting motor 14 drives one of the rotating seats 13 to rotate. The synchronous component includes a synchronous wheel 16 fixedly sleeved on the outside of the rotating seat 13. An auxiliary wheel 17 is slidably provided on the operation board 5 between the two synchronous wheels 16. A synchronous belt 18 is sleeved on the outside of the two synchronous wheels 16 and an auxiliary wheel 17. The tension of the synchronous belt 18 is achieved by the lateral sliding of the auxiliary wheel 17.

[0031] Since the auxiliary wheel 17 needs to be self-locked after sliding and the moving frequency of the auxiliary wheel 17 is not high, a trapezoidal lead screw can be considered to achieve sliding adjustment and self-locking.

[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes, shall be covered by the protection scope of the present utility model.
