Description

Technical Field

[0001] The invention belongs to the field of agricultural machinery, and in particular relates to a device and method for synchronously cutting rootstocks and scions of multiple parallel grafted Solanaceae vegetables. Background Art

[0002] As vegetable planting tends to be regionalized and specialized, continuous cropping and repeated cropping are more common, and diseases tend to occur more seriously. The relatively single crop type and year-round facility coverage cause ecological imbalance in local areas, serious secondary salinization, weak soil self-purification ability, and accumulation of pests and diseases, which lead to growth and development disorders of crops, reduced yields, and decreased quality. Vegetable grafting cultivation is a technical measure that can effectively prevent and control soil-borne diseases. At present, vegetable grafting operations are basically still in the manual stage, but manual grafting is affected by many factors, which will lead to inconsistent cutting quality between stock and scion, resulting in incomplete fitting of the cutting surface of stock and scion, which in turn affects the survival rate of grafted seedlings. In order to improve the cutting quality and survival rate of grafted seedlings and reduce labor costs, it is urgently necessary to provide a new synchronous cutting device for parallel grafting of multiple rootstocks and scions of Solanaceae vegetables.

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned purpose, features and advantages of the present invention more obvious and easy to understand, the specific implementation mode of the present invention is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. The technical features in each embodiment of the present invention can be combined accordingly without conflicting with each other.

[0036] In the description of the present invention, it is to be understood that when an element is considered to be "connected" to another element, it may be directly connected to the other element or indirectly connected, that is, there are intermediate elements. On the contrary, when an element is said to be "directly" connected to another element, there are no intermediate elements.

[0037] In the description of the present invention, it should be understood that the terms "first" and "second" are only used for the purpose of distinguishing descriptions, and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0038] In the present invention, for the convenience of description, Figure 2 The coordinate axis directions in the figure are used as reference to illustrate the positional relationship of the components in the device of the present invention. The "outer side" and "inner side" of the clamping mechanism refer to Figure 1 The lower and upper sides of the cutting blade mechanism refer to the “outer side” and “inner side” of the cutting blade mechanism. Figure 1 If there is no special explanation, the positional relationship of the present invention is described as follows.

[0039] like Figure 1 As shown, a synchronous cutting device for parallel grafting rootstocks and scions of multiple Solanaceae vegetables provided by the present invention mainly comprises a cutting knife mechanism 01 and a clamping mechanism 02 mounted on a frame 03. Each mechanism cooperates with each other to achieve the synchronous cutting function of parallel grafting rootstocks and scions of multiple Solanaceae vegetables, and the cooperation process is described below.

[0040] like Figure 2 As shown, the clamping mechanism 02 is used to clamp the rootstock seedling and the scion seedling through the clamping end 0205, and to limit the rootstock seedling and the scion seedling in the X-axis and Y-axis directions through the limiting plate 0206 and the knife groove 0209 opened on the limiting plate 0206.

[0041] like Figure 3 As shown, the above-mentioned cutting knife mechanism 01 is installed downstream of the clamping mechanism 02, including a cutting blade 0107 arranged on the cutting knife base 0106; the cutting knife base 0106 can move along the Y-axis direction, driving the cutting blade 0107 to be embedded in the knife groove 0209, so as to synchronously cut the rootstock seedlings and scion seedlings on the clamping mechanism 02, and the cutting angles and cross-sectional shapes of the rootstock seedlings and scion seedlings are consistent, so as to facilitate the subsequent grafting process.

[0042] Theoretically, the structural form of the above-mentioned cutting knife mechanism 01 and the clamping mechanism 02 is not limited, as long as the functions described above can be realized. As a preferred mode of the above-mentioned device, the cutting knife mechanism may include a first slide cylinder for driving a cutting knife mounting plate, a first slide cylinder output plate for connecting the first slide cylinder and the cutting knife mounting plate, and a cutting knife mounting plate for mounting a cutting blade; the clamping mechanism may include a second slide cylinder for driving a limit plate, an electric push rod for driving a clamping power source mounting plate, a clamping power source mounting plate for mounting a clamping power source and a clamping end, a clamping power source for providing a driving force for the clamping end, a clamping end for clamping a stock seedling and a scion seedling, a limit plate for limiting the stock seedling and the scion seedling in the Y-axis, and a knife groove for limiting the stock seedling and the scion seedling in the X-axis and corresponding to the cutting blade to achieve cutting.

[0043] The preferred implementation forms of each mechanism are described in detail below through embodiments in conjunction with the accompanying drawings.

[0044] The specific form of the frame 03 of the present invention can be adjusted according to actual needs, and its main function is to provide installation positions for various functional mechanisms. Considering aesthetics and convenience, the frame 03 can be set as two horizontal plate-like structures that can be installed on the full-automatic grafting machine, which are used to fix the cutting knife mechanism and the clamping mechanism respectively. The cutting knife mechanism and the clamping mechanism are both installed on the frame 03, in the same horizontal plane, and arranged oppositely, so that the cutting blades in the cutting knife mechanism correspond one by one to the knife grooves in the clamping mechanism.

[0045] In a preferred embodiment of the present invention, the cutter mechanism 01 mainly includes a first slide cylinder 0101, a first slide cylinder output plate 0102 and a cutter mounting plate 0103.

[0046] Specifically, the bottom of the first slide cylinder 0101 is fixed to the upper surface of the frame 03, and can be driven along the Y-axis direction. The output end of the first slide cylinder 0101 is connected to the first slide cylinder output plate 0102, and the surface of the first slide cylinder output plate 0102 is parallel to the Z-axis. One side (i.e., the inner side) of the first slide cylinder output plate 0102 is connected to the output end of the first slide cylinder 0101, and the other side (i.e., the outer side) is connected to the cutter mounting plate 0103, and the surface of the cutter mounting plate 0103 is also parallel to the Z-axis. The first slide cylinder 0101 can drive the cutter mounting plate 0103 to move along the Y-axis direction.

[0047] In actual use, the first slide cylinder output plate 0102 is connected to the output end of the first slide cylinder 0101 as a whole, and the first slide cylinder output plate 0102 is usually not disassembled. The first slide cylinder output plate 0102 is preferably a square plate. Figure 5As shown, the cutting blade mounting plate 0103 is generally rectangular, with two square holes equidistantly opened in the center, and two vertical grooves symmetrically opened on the inner side. The depth of the vertical grooves is preferably 1 mm, and two L-shaped connecting plates 0105 are detachably embedded in the two vertical grooves and the two square holes for installation. Figure 2 As shown, the L-shaped connecting plate 0105 includes a first plate surface arranged parallel to the X-axis and a second plate surface arranged parallel to the Y-axis. The joint of the two plate surfaces is raised and embedded in the vertical groove of the cutting tool mounting plate 0103 for installation. The two first plate surfaces are respectively embedded in the two square holes. The two vertical grooves and the two square holes play a positioning role, so that the L-shaped connecting plate is clamped in the cutting tool mounting plate 0103 for installation. At this time, a square groove is formed between the two first plate surfaces parallel to the X-axis and the cutting tool mounting plate 0103. The square groove is located in the middle of the cutting tool mounting plate 0103, and the first slide cylinder output plate 0102 on the output end of the first slide cylinder 0101 can be embedded in the square groove, and then the two are connected by a bolt. This design is for the convenience of disassembly and assembly of the cutting tool mounting plate 0103. Since the cutting blade 0107 is a wearing part, it will often come into contact with the juice of the grafted seedlings during use and is prone to rust. After the cutting tool mounting plate 0103 is removed, the cutting blade 0107 can be quickly and easily replaced.

[0048] In a preferred embodiment of the present invention, the plate surface of the cutting blade mounting plate 0103 is vertical, and its outer side surface is provided with n (n is a positive integer) oblique grooves 0104, each oblique groove 0104 is parallel to each other and arranged at intervals along the X-axis direction, and a cutting blade base 0106 is installed in each oblique groove 0104. The upper and lower parts of the cutting blade base 0106 are respectively provided with cutting blades 0107 with the blades facing outwards, and the inclination angles of the blades of the two cutting blades 0107 are the same and the upper and lower parts are coaxially arranged. In order to ensure that the cutting blade can completely cut off the rootstock seedling and the scion seedling, the width of the blade should be wide enough. In this embodiment, the width of the cutting blade is 20 mm.

[0049] In actual use, Figure 4 As shown, the number of the oblique grooves 0104 is five (ie, n=5), and the five cutting tool bases 0106 can just fit into each oblique groove 0104 for positioning and installation. Figure 6 As shown, the cutting tool base 0106 is a V-shaped structure, including two connected sides, one side is detachably mounted in the oblique groove 0104 by bolts, and the other side extends obliquely upward. Figure 3As shown, the cutting blade 0107 includes a scion cutting blade and a stock cutting blade, wherein the scion cutting blade is installed on an edge located at the upper part of the cutting blade base 0106, and the stock cutting blade is installed on an edge located at the lower part of the cutting blade base 0106. The inclination angles of the scion cutting blade and the stock cutting blade are both 60°. When observed from a top-down angle parallel to the Z-axis direction, the upper scion cutting blade and the lower stock cutting blade are both located on the same straight line, so that the cutting angles and cutting surface shapes of the stock seedling and the scion seedling can be guaranteed to be consistent. When cutting the stock seedling and the scion seedling, the incision angles on the stock seedling and the scion seedling are both 30°. This smaller angle allows the incisions of the stock seedling and the scion seedling to have a larger area, so that they also have a large area of ​​fit when fitting, thereby improving the survival rate of the grafted seedlings.

[0050] In the initial state, the first slide cylinder 0101 contracts, and the cutting blade 0107 is also in a state of waiting for cutting; when entering the working process, the first slide cylinder 0101 extends to push the two rows of cutting blades 0107 (stock cutting blades and scion cutting blades) forward for cutting movement.

[0051] In a preferred embodiment of the present invention, the clamping mechanism 02 mainly includes a second slide cylinder 0201, an electric push rod 0202, a clamping power source mounting plate 0203, a clamping power source 0204, a clamping end 0205 and a limit plate 0206.

[0052] Specifically, the second slide cylinder and the electric push rod are both fixedly connected to the frame along the Y direction relative to the first slide cylinder, and their installation positions are parallel to each other, respectively providing Y-direction translational force for the grafted seedling limit plate and the clamping power source mounting plate; the power source of the electric push rod is a motor, which can be stopped at any position. The function of the electric push rod is to push the clamping power source to move forward and backward. Due to the process requirements, the clamping power source has multiple positions for movement, so the electric push rod is selected to achieve this function.

[0053] In a preferred embodiment of the present invention, the bottom of the second slide cylinder 0201 is fixed to the upper surface of the frame 03, and can be driven along the Y-axis direction. Figure 3 As shown, the output end of the second slide cylinder 0201 is connected to the second slide cylinder output plate 0212. The second slide cylinder output plate 0212 is a horizontal plate, one side of which is connected to the output end of the second slide cylinder 0201, and the other side of which is connected to the limit plate 0206. The limit plate 0206 can be driven to move along the Y-axis direction through the second slide cylinder 0201.

[0054] Specifically, Figure 8As shown, the limit plate 0206 is an L-shaped structure, including a horizontal plate and a vertical plate. The horizontal plate is connected to the second slide cylinder output plate 0212, and a group of clamping end grooves 0208 are respectively opened at the upper and lower parts of the vertical plate surface, and each group of clamping end grooves 0208 includes n (n=5 in this embodiment) clamping end sub-grooves spaced along the X-axis direction, and the size of the clamping end sub-grooves should be able to allow the clamping end 0205 to pass along the Y-axis direction. The positions of the clamping end sub-grooves in the upper and lower groups correspond. The outer side of each clamping end sub-groove is opened with a knife groove 0209 corresponding to the blade of the cutting blade 0107, and the upper and lower two knife grooves 0209 are a group and correspond to the positions of the two cutting blades 0107 of the cutting tool base 0106. It should be noted that the outer side of each clamping end sub-groove refers to: the upper side of a group of clamping end grooves 0208 located at the upper part of the vertical plate surface and the lower side of a group of clamping end grooves 0208 located at the lower part of the vertical plate surface. When the cutting knife base 0106 moves along the Y-axis direction, the two cutting blades 0107 can be respectively embedded in the corresponding upper and lower knife grooves 0209 to synchronously cut the rootstock seedlings and the scion seedlings.

[0055] like Figure 7 The schematic diagram of the partial structure of the limit plate 0206 shown clearly shows the partial structure of the vertical surface of the limit plate. A knife groove 0209 is opened in the position close to each scion seedling clamping end groove (i.e., each clamping end sub-groove in the upper group), and the opening of the knife groove expands to both ends, the purpose of which is to enable the seedling to smoothly enter the knife groove and facilitate subsequent cutting operations; similarly, a cutting knife groove is opened in the position close to each stock clamping end groove (i.e., each clamping end sub-groove in the lower group), and its opening expands to both ends, the purpose is the same as above. Specifically, on the vertical surface of the limit plate, a U-shaped groove is opened at two positions, namely, the upper and lower positions corresponding to the positions of the upper and lower 5 parallel guide cylinders, so that the clamping end extends from the U-shaped groove to clamp the stock and the scion; the upper 5 U-shaped grooves serve as scion clamping end grooves, and the lower 5 U-shaped grooves serve as stock clamping end grooves. At the position close to the end groove of the scion clamp, there is a knife groove inclined at 60°, the purpose of which is to provide shelter for the cutting blade. When the cutting blade cuts in, the blade will enter the knife groove; similarly, at the position close to the bottom of the end groove of the stock clamp, there is a knife groove inclined at 60°, its function is the same as above and will not be repeated here.

[0056] In addition, the plate surface of the second slide cylinder output plate 0212 is arranged horizontally, and two second slide rails are symmetrically fixed on both sides of the bottom surface along the Y-axis direction, and the two second slide rails are respectively slidably connected with second sliders, and the second sliders are fixed on the top of the Z-shaped mounting plate 0207, and the bottom of the Z-shaped mounting plate 0207 is fixed on the frame 03. The two second slide rails and the two second sliders together serve as the second slider rail group 0211. The second slide cylinder 0201 can drive the second slide cylinder output plate 0212 to move under the limit of the second slider rail group 0211. The moving state of the second slider rail group 0211 is: the second slider is fixed, and the second slide rail moves synchronously with the limit plate 0206.

[0057] In a preferred embodiment of the present invention, the bottom of the electric push rod 0202 is fixed to the upper surface of the frame 03, and can be driven along the Y-axis direction. The output end of the electric push rod 0202 is connected to the clamping power source mounting plate 0203, and the clamping power source mounting plate 0203 can be driven to move along the Y-axis direction through the electric push rod 0202.

[0058] Specifically, Fig. 9 As shown, the bottom of the clamping power source mounting plate 0203 is arranged horizontally, and three first sliders are evenly distributed and fixedly installed on the bottom surface along the Y-axis direction, each first slider is slidably connected to the first slide rail, and the first slide rail is fixed on the frame 03, and the first slide rail is arranged along the Y-axis direction. For example, in this embodiment, three slide rails and three sliders are used, that is, three first slide rails and three first sliders are used together as the first slider slide rail group 0210. The clamping power source mounting plate 0203 can be driven to move under the limit of the first slider slide rail group 0210 through the electric push rod 0202. In this embodiment, the clamping power source mounting plate 0203 is divided into a first mounting plate and a second mounting plate. Four sliders are connected to the lower surface of the first mounting plate, and the matching slide rails are fixed on the frame. The sliders and slide rails are collectively referred to as first sliders and slide rails 0210. At the same time, the first mounting plate is connected to the output end of the electric push rod 0202. Under the drive of the electric push rod 0202, the sliders and slide rails are matched to realize the movement of the first mounting plate on the frame. The first mounting plate is L-shaped, and the other side of the first mounting plate is connected to the second mounting plate. The movement of the first mounting plate brings the second mounting plate with it, and the second mounting plate is T-shaped.

[0059] In a preferred embodiment of the present invention, Fig.10 As shown, 2n clamping power sources 0204 are arranged on the clamping power source mounting plate 0203, that is, each clamping power source 0204 corresponds to a clamping terminal sub-groove, and the output end of each clamping power source 0204 is provided with a clamping terminal 0205 capable of clamping and releasing the rootstock seedling or scion seedling. The clamping power source 0204 is located behind the clamping terminal sub-groove, so that the clamping terminal 0205 can be extended or retracted from the clamping terminal sub-groove under the drive of the clamping power source 0204.

[0060] Specifically, the clamping power source 0204 is a parallel guide cylinder, which can realize outward opening and inward clamping operations. Parallel guide cylinder sliders are respectively provided on both sides of the parallel guide cylinder, and the two parallel guide cylinder sliders can move closer to the middle or separate to both sides under the action of the parallel guide cylinder. A clamping claw extending outward is vertically installed on each guide cylinder slider, and the two clamping claws located on the same parallel guide cylinder constitute the clamping end 0205, which can clamp or release the rootstock seedling or scion seedling under the action of the parallel guide cylinder.

[0061] In this embodiment, the clamping end is divided into a scion clamping end (i.e., a group of clamping ends located at the upper part) and a stock clamping end (i.e., a group of clamping ends located at the lower part). The clamping ends are all installed on the output ends of the parallel guide cylinder. A pair of clamping ends are respectively installed at the two output ends of the parallel guide cylinder, one on the left and one on the right, and are installed 1mm apart from each other. The clamping end on the left is on the top, and the clamping end on the right is on the bottom. The purpose is to ensure a larger clamping range while making the clamping effect more solid. The parallel guide cylinders are installed in parallel on the upper and lower sides of the second mounting plate. The scion clamping end is installed on the upper parallel guide cylinder, and the stock clamping end is installed on the lower parallel guide cylinder. There are 10 cylinders in total, 5 cylinders on the upper and lower sides (i.e., n=5 in this embodiment), and the spacing between the five cylinders on each side is 47mm.

[0062] By using the above-mentioned synchronous cutting device for parallel grafting rootstocks and scions of multiple Solanaceae vegetables, the present invention also provides an operation method for synchronous cutting of parallel grafting rootstocks and scions of multiple Solanaceae vegetables, and the operation method specifically comprises the following steps:

[0063] In the initial state, the second slide cylinder 0201 and the electric push rod 0202 are both in a retracted state, so that the limit plate 0206 and the clamping end 0205 are both in the rear initial position. At this time, the clamping end 0205 does not extend from the clamping end slot 0208, and the limit plate 0206 does not limit the stock seedling and the scion seedling.

[0064] When the electric push rod 0202 is extended, there are two stop positions. The first position is set at the maximum stroke, and the second position is retreated a short distance from the first position.

[0065] In the running state, the electric push rod 0202 drives the clamping power source mounting plate 0203 to drive the clamping end 0205 to move forward a certain distance to reach the first position (i.e., the maximum stroke), so that the clamping end 0205 extends from the clamping end slot 0208. At this time, the n scion seedlings are respectively in a row of clamping ends 0205 above the clamping power source mounting plate 0203, and the n rootstock seedlings are respectively in a row of clamping ends 0205 below the clamping power source mounting plate 0203. Subsequently, each clamping power source 0204 drives the corresponding clamping end 0205 to clamp synchronously to achieve the clamping of the rootstock seedlings and the scion seedlings. Then, the second slide cylinder 0201 drives the limit plate 0206 to move forward a certain distance, so that the vertical plate surface of the limit plate 0206 is just close to the rear of the rootstock seedlings and the scion seedlings clamped by the clamping end 0205, and the rootstock seedlings and the scion seedlings are limited in the Y-axis direction. Subsequently, the electric push rod 0202 drives the clamping power source mounting plate 0203 to drive the clamping end 0205 to move backward (in this embodiment, it moves 2 mm backward to reach the second position), so that each rootstock seedling and scion seedling is respectively gathered into the corresponding knife grooves 0209 on the vertical plate surface of the limiting plate 0206, thereby limiting the rootstock seedlings and scion seedlings in the X-axis direction.

[0066] After the above processes are completed, the rootstock and scion seedlings will be cut synchronously, as follows: the first slide cylinder 0101 extends, drives the cutting blade mounting plate 0103 to carry the cutting blade 0107 to perform cutting movement along the Y-axis direction, at which time, the rootstock seedling and scion seedling clamped and limited by the clamping mechanism 02 are respectively located on the moving path of the corresponding cutting blade 0107. When the first slide cylinder 0101 extends to the maximum stroke, it drives the cutting blade 0107 to just enter the corresponding knife groove 0209, and the rootstock seedling and scion seedling are both in the knife groove, thereby completing the synchronous cutting of the rootstock seedling and scion seedling in the knife groove 0209. After the cutting is completed, the first slide cylinder 0101 drives the cutting blade 0107 to reset and retract, the clamping power source 0204 drives the clamping end 0205 to release, the electric push rod 0202 drives the clamping power source mounting plate 0203 to reset and retract, and the second slide cylinder 0201 drives the limit plate 0206 to reset and retract.

[0067] The present invention is used for synchronous cutting of the rootstock and the scion on the fully automatic grafting machine of Solanaceae vegetables. Compared with the traditional cutting method, the present invention can cut the rootstock and the scion at the same time, and the cutting angle and the cutting surface shape are consistent, which is beneficial to the subsequent grafting operation and the docking of the rootstock and the scion. Not only can the cutting surfaces be matched and fitted with each other, but the grafted seedlings after fitting can also maintain a good uprightness, thereby improving the survival rate of the grafted seedlings.

[0068] The above-described embodiment is only a preferred solution of the present invention, but it is not intended to limit the present invention. A person skilled in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
