Description

Technical Field

[0001] The present invention belongs to the technical field of forestry seedling raising, and particularly relates to a cutting device for forestry seedling raising. Background Art

[0002] Cutting propagation is one of the important ways of plant propagation, especially for plants that are not easy to produce seeds, this method is mostly used. It is to cut a section of the vegetative organ of the cutting seedling, insert it into loose and moist soil or fine sand, and use its regeneration ability to make it take root and sprout into a new cutting seedling. The cutting seedlings obtained in this way can maintain the excellent characteristics of the variety, and the material source is wide and the propagation cycle is short.

[0017] Further, the mounting bracket is provided with mounting ears for mounting.

[0018] The above at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0019] First, the adjustment motor of the present invention works to drive the first adjustment gear to rotate. When the first adjustment gear rotates, it will drive the second adjustment gear to rotate, thereby driving the rotation of the rotating shaft to drive the position of the adjustment frame to rotate on the mounting bracket, thereby adjusting the position of the punching rod so that the position of the punching rod is in an inclined state. Then the adjustment motor stops working to lock and fix the position of the adjustment frame;

[0020] When cuttings are being inserted, making an inclined hole has the following advantages:

[0021] Increasing the contact area: The inclined hole can significantly increase the contact area between the cutting and the substrate. Taking poplar cuttings as an example, the contact area between the cutting and the substrate during inclined hole cutting can be increased by about 30%-40% compared with straight hole cutting. A larger contact area is beneficial for the cutting to absorb more water and nutrients from the substrate, providing a sufficient material basis for rooting, thereby increasing the rooting rate.

[0022] Improving ventilation and air permeability: The angle of the inclined hole is conducive to the flow of air in the substrate, enabling the base of the cutting to obtain more sufficient oxygen. For some tree species with high oxygen requirements, such as pine trees, good ventilation and air permeability conditions can promote the respiration of the cells at the base of the cutting, accelerate metabolism, and create favorable conditions for rooting.

[0023] Second, in the present invention, the depth of the cutting can be adjusted according to the different depths of the cutting holes, so that the depth of the cutting is the same as and adapted to the depth of the cutting hole, which has the following advantages:

[0024] Fixing and supporting: It can provide stable support for the cutting, enabling it to grow upright or at the expected angle, preventing the cutting from lodging or shaking. This is beneficial for the cutting to remain stable during the rooting process, avoiding mechanical damage that may affect healing and rooting. At the same time, proper fixing also helps the cutting to come into close contact with the cutting substrate, promoting the absorption of water and nutrients.

[0025] Promote healing and rooting: The cutting is adapted to the depth of the cutting hole, which can make the base of the cutting fully contact with the cutting substrate, facilitating the formation of a suitable humidity and temperature environment and promoting the formation of callus and the growth of roots. If the cutting is too short, the contact area with the substrate is small, which will affect the absorption of water and nutrients and is not conducive to rooting; while if the cutting is too long and inserted too deep, it may lead to oxygen deficiency at the base and also have an adverse effect on rooting.

[0026] Prevent water loss: When the depth of the cutting is the same as that of the cutting hole, the substrate around the cutting can better retain water, reducing the part of the cutting exposed to the air, thereby reducing the rate of water loss. This helps to maintain the water balance of the cutting, prevent the cutting from drying out due to excessive water loss, and improve the survival rate of cutting.

[0027] Reduce the risk of infection: The appropriate depth can keep the cutting in a relatively stable and clean environment in the cutting hole, reducing the chance of invasion by external pathogens, pests, etc. The tight fit between the cutting and the cutting hole can also prevent impurities or microorganisms in the substrate from entering due to excessive gaps, thereby reducing the risk of disease infection.

Detailed implementation manners

[0041] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0042] The following will, with reference to the accompanying drawings, detail the technical solutions provided by the embodiments of the present invention for a forestry seedling cutting device.

[0043] Refer to Figures 1 to 10As shown in the figure, an embodiment of the present invention provides a forestry seedling cutting device, including a mounting frame 1; the mounting frame 1 is used for fixing the overall device; a cutting adjustment structure 2, the cutting adjustment structure 2 is arranged on the mounting frame 1, and the cutting adjustment structure 2 is rotatably connected to the mounting frame 1; a cutting moving structure 3, the cutting moving structure 3 is arranged on the cutting adjustment structure 2, and the cutting moving structure 3 is slidably matched with the cutting adjustment structure 2; a cutting driving structure 4, the cutting driving structure 4 is arranged on the cutting moving structure 3; a cutting hole punching structure 5, the cutting hole punching structure 5 is arranged on one side of the cutting adjustment structure 2, and the cutting hole punching structure 5 is slidably matched with the cutting adjustment structure 2; a cutting spike inserting structure 6, the cutting spike inserting structure 6 is arranged on the other side of the cutting adjustment structure 2, and the cutting spike inserting structure 6 is slidably matched with the cutting adjustment structure 2.

[0044] Specifically, the cutting adjustment structure 2 includes an adjustment motor 21, an adjustment frame 22, a first adjustment gear 23 and a second adjustment gear 24. Both ends of the adjustment frame 22 are provided with rotating shafts 25. The adjustment frame 22 is rotatably connected to the side wall of the mounting frame 1 through the two rotating shafts 25. The adjustment motor 21 is located on the mounting frame 1. The first adjustment gear 23 is connected to the main shaft of the adjustment motor 21. The second adjustment gear 24 is located on one of the rotating shafts 25. The first adjustment gear 23 is meshed with the second adjustment gear 24. Two rows of a plurality of equally spaced insertion holes 26 and moving holes 27 are provided on the bottom side wall of the adjustment frame 22.

[0045] When the cutting spike is inserted vertically, the position of the adjustment frame 22 is in a state of overlapping with the mounting frame 1. At this time, the punching rod 53 on the adjustment frame 22 is in a vertical state, so as to insert the cutting spike vertically downward.

[0046] When some cutting spikes need to be inserted obliquely, the adjustment motor 21 works to drive the first adjustment gear 23 to rotate. The rotation of the first adjustment gear 23 will drive the second adjustment gear 24 to rotate, thereby driving the rotating shaft 25 to rotate and driving the position of the adjustment frame 22 to rotate on the mounting frame 1, so as to adjust the position of the punching rod 53 to make the position of the punching rod 53 in an inclined state. Then the adjustment motor 21 stops working to lock and fix the position of the adjustment frame 22.

[0047] When the cutting spike is inserted, there are the following advantages in making an oblique hole:

[0048] Increasing the contact area: The oblique hole can significantly increase the contact area between the cutting spike and the substrate. Taking the cutting of poplar as an example, the contact area between the cutting spike and the substrate during oblique hole cutting can be increased by about 30%-40% compared with straight hole cutting. A larger contact area is beneficial for the cutting spike to absorb more water and nutrients from the substrate, providing a sufficient material basis for rooting, thereby improving the rooting rate.

[0049] Improve ventilation: The angle of the inclined holes is conducive to the circulation of air in the substrate, enabling the base of the cutting to obtain more sufficient oxygen. For some tree species with high oxygen requirements, such as pine trees, good ventilation conditions can promote the respiration of the cells at the base of the cutting, accelerate metabolism, and create favorable conditions for rooting.

[0050] Specifically, the cutting moving structure 3 includes a first support plate 31, a second support plate 32, a mounting frame 33, a mounting block 34, a moving motor 35, and a moving gear 36. The first support plate 31 and the second support plate 32 are symmetrically and horizontally arranged on the inner side walls of the adjustment frame 22. The mounting frame 33 is slidably connected to the first support plate 31, the mounting block 34 is slidably connected to the second support plate 32. A motor bracket 37 is provided on the side wall of the mounting frame 33. The moving motor 35 is located on the motor bracket 37, the moving gear 36 is located on the main shaft of the moving motor 35, and a moving rack 38 meshing with the moving gear 36 is provided on the side wall of the first support plate 31;

[0051] The cutting driving structure 4 includes a driving motor 41, a driving shaft 42, and four driving plates 43. The driving motor 41 is located inside the mounting frame 33. One end of the driving shaft 42 is arranged on the main shaft of the driving motor 41, and the other end of the driving shaft 42 is located on the mounting block 34. The four driving plates 43 are equidistantly arranged on the driving shaft 42;

[0052] A lengthening plate 44 is provided at the bottom of each driving plate 43. Four sliders 45 are provided on the lengthening plate 44. The lengthening plate 44 is slidably connected to the driving plate 43 through the four sliders 45. A driving electric cylinder 46 is provided inside the driving plate 43, and the telescopic end of the driving electric cylinder 46 is connected to the lengthening plate 44.

[0053] When the moving motor 35 works, it drives the moving gear 36 to rotate and drives the rotation on the moving rack 38, thereby driving the mounting frame 33 to move horizontally on the first support plate 31, and thus driving the position of the mounting block 34 to move horizontally on the second support plate 32 through the driving shaft 42. During the process of cutting the cutting, the position of the cutting driving structure 4 can be driven to move left and right, and the position of the cutting driving structure 4 can be moved above the cutting hole punching structure 5 or the cutting inserting structure 6.

[0054] During the process of punching holes, the driving motor 41 works to drive the driving shaft 42 to rotate, thereby driving the four driving plates 43 to rotate, and thus performing the punching work on the substrate.

[0055] During the hole punching process, the driving electric cylinder 46 works to drive the extension plate 44 to move on the driving plate 43 through four sliders 45, which will drive the position of the extension plate 44 to move outward. The outward movement of the position of the extension plate 44 will increase the contact area with the cutting and hole punching structure 5, thereby driving the position of the punching rod 53 to move downward by a longer distance. During the process of punching holes in the substrate, the cutting depth can be adjusted according to the needs of cutting.

[0056] It can adapt to different cutting lengths: The cutting lengths of different plants vary. Punching cutting holes of different depths can meet the needs of various cutting lengths, making the cutting match the depth of the cutting hole. For example, for the cutting of shorter herbaceous plants, shallower cutting holes can provide sufficient support and fixation; while for the longer cuttings of woody plants, deeper cutting holes are required to ensure that most of the cuttings can be inserted into the substrate, which is beneficial for the base of the cuttings to fully contact the substrate, absorb water and nutrients, and promote rooting.

[0057] It can adjust the rooting environment: Cutting holes of different depths can create different temperature, humidity and air permeability environments to adapt to the rooting needs of different plant cuttings. Generally speaking, shallower cutting holes are closer to the substrate surface, with relatively larger temperature changes and better air permeability, but relatively weaker water retention ability, which is suitable for some plant cuttings that require higher air permeability and are not tolerant to waterlogging, such as succulents. Deeper cutting holes are inside the substrate, with relatively stable temperature and higher humidity, which is beneficial for the rooting of some plant cuttings that require higher humidity, such as gardenias. By adjusting the depth of the cutting hole, a more suitable rooting environment can be provided for different plant cuttings, improving the cutting survival rate.

[0058] During the subsequent cutting process of the cuttings, the extension plate 44 can drive the adjustment of the cutting depth of the cuttings; in the present invention, the depth of the cuttings can be adjusted according to the different depths of the cutting holes, so that the depth of the cuttings is the same as and matches the depth of the cutting holes, which has the following advantages:

[0059] Fixation and support: It can provide stable support for the cuttings, making them stand upright or grow at the expected angle, preventing the cuttings from lodging or shaking. This is beneficial for the cuttings to remain stable during the rooting process and avoid affecting healing and rooting due to mechanical damage. At the same time, proper fixation also helps the cuttings to closely contact the cutting substrate, promoting the absorption of water and nutrients.

[0060] Promote healing and rooting: The cuttings are adapted to the depth of the cutting holes, which can make the base of the cuttings fully contact the cutting substrate, facilitating the formation of a suitable humidity and temperature environment and promoting the formation of callus and the growth of roots. If the cuttings are too short, the contact area with the substrate is small, which will affect the absorption of water and nutrients and is not conducive to rooting; while if the cuttings are too long and inserted too deep, it may lead to oxygen deficiency at the base, which will also have an adverse effect on rooting.

[0061] Preventing water loss: When the depth of the cutting is the same as that of the cutting hole, the substrate around the cutting can better retain moisture, reducing the part of the cutting exposed to the air, thereby reducing the rate of water loss. This helps to maintain the water balance of the cutting, prevent the cutting from drying out due to excessive water loss, and improve the survival rate of cutting.

[0062] Reducing the risk of infection: The appropriate depth can make the cutting in a relatively stable and clean environment within the cutting hole, reducing the chance of invasion by external pathogens, pests, etc. to the cutting. The tight fit between the cutting and the cutting hole can also prevent impurities or microorganisms in the substrate from entering due to excessive gaps, thereby reducing the risk of disease infection.

[0063] Specifically, the cutting hole punching structure 5 includes a first horizontal plate 51, four first connection blocks 52, and a plurality of punching rods 53 arranged at equal intervals at the bottom of the first horizontal plate 51. The four first connection blocks 52 are arranged at equal intervals on the top of the first horizontal plate 51. The first horizontal plate 51 is horizontally arranged at the top position of the plurality of punching rods 53. The punching rods 53 move downward in the corresponding jacks 26. The bottom of the punching rod 53 is provided with a sharp punching tip 54. A return spring 55 is arranged in the punching rod 53, and the return spring 55 is connected between the first horizontal plate 51 and the jack 26.

[0064] When punching the substrate, by rotating the four extension plates 44 on the cutting driving structure 4 on the four first connection blocks 52, the position of the first horizontal plate 51 will be driven to move downward, thereby driving the positions of the plurality of punching rods 53 to move downward. By the punching tip 54 moving downward, the substrate can be punched. After punching is completed, after the position of the extension plate is disengaged from the first connection block, the position of the punching rod 53 can be reset upward through the corresponding return spring 55 for the next punching of the substrate.

[0065] Specifically, the cutting inserting structure 6 includes a second horizontal plate 61, four second connection blocks 62, and a plurality of moving rods 63 arranged at equal intervals. The four second connection blocks 62 are arranged at equal intervals on the top of the second horizontal plate 61. The plurality of moving rods 63 are arranged at equal intervals on the top of the second horizontal plate 61. The moving rods 63 move up and down in the moving holes 27. A moving spring 64 is arranged between the moving rods 63 and the moving holes 27. The adjustment frame 22 is provided with a moving groove 28 at the position of the moving holes 27. A moving frame 65 is arranged on the side wall of the moving rod 63. Two placing blocks 66 are arranged on the moving frame 65, and each placing block 66 is provided with a clamping claw 67 for clamping the cutting.

[0066] Manually place the upper ends of the cuttings on two clamping claws 67 respectively. The two clamping claws 67 can automatically clamp the upper part of the cuttings. Then, four extension plates 44 on the cutting drive structure 4 rotate on four second connection blocks 62, which will drive the position of the second horizontal plate 61 to move downward, thereby driving the positions of several moving rods 63 to move downward, and then driving the position of the moving frame 65 to move downward in the moving groove 28. The downward movement of the position of the moving frame 65 will drive the position of the clamped cuttings to move downward, and insert the cuttings into the corresponding cutting holes, thereby realizing the cutting work of the cuttings. The moving spring 64 can reset the second horizontal moving plate 61 upward after the cuttings are inserted into the cutting holes and the clamping claws 67 release the cuttings, and the position of the extension plate disengages from the second connection block 62.

[0067] Specifically, mounting ears 11 for installation are provided on the mounting frame 1. The mounting ears 11 are used to mount the overall device structure on the vehicle frame for driving seedling cutting, and can drive the seedling cutting device to move forward to cut cuttings at different positions.

[0068] The above are only embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
