Description

Technical Field

[0001] The utility model relates to the technical field of tomato grafting, in particular to an adjustable tomato grafting cutting device. Background Art

[0002] Tomatoes are the most common among vegetables. Combining tomatoes with disease-resistant rootstocks can significantly improve the disease resistance of tomato plants and reduce the occurrence of diseases.

[0003] When grafting tomatoes and rootstocks, generally two methods are used: the top grafting method and the side grafting method. In the top grafting method, the rootstock is cut off from the top, and the top is divided into two parts with a cutter. Then, the bottom of the tomato is cut into an inclined plane, and the inclined plane at the bottom of the tomato is inserted into the top of the rootstock and fixed with a grafting clip. The side grafting method is to make inclined cuts on the side of the rootstock stem and the side of the tomato stem respectively, and then clamp them together and fix them with a grafting clip.

[0004] In traditional plug grafting operations, the side grafting method is generally used. Because the side grafting method provides more choices for grafting positions. The original tops of the scion and the rootstock can be treated separately, which helps to reduce the competition between the top of the scion and the rootstock, enabling nutrients to be more concentratedly supplied to the scion and promoting its growth. The plants grafted by the side grafting method are more adaptable to the environment because the roots of the scion and the rootstock can respond to different environmental conditions respectively, thus enhancing the stress resistance of the whole plant.

[0005] However, the following defects exist in the prior art:

[0006] When using a cutting knife to make inclined cuts on the rootstock stem and the tomato stem, it is easy to cut them in half if the force is not well grasped, and the inclined cut depths are inconsistent, and it is difficult for them to heal and grow subsequently. Summary of the Utility Model

[0007] To solve the technical problem of poor depth control during inclined cutting and unsuccessful grafting, the utility model provides an adjustable tomato grafting cutting device, which includes a housing. A slider is arranged in the housing through a clamping mechanism, and a cutter is fixed on the slider. The cutter can penetrate through the housing for cutting operations;

[0008] Scale lines, which are distributed on the cutter and used as cutting scale marks;

[0009] Cleaning mechanism, the cleaning mechanism includes a first slot, two first round rods, two sponges, a first belt and a driving unit. The first slot is opened in the housing. A second slot is opened in the inner wall of the housing below the first slot. Both ends of one of the first round rods are fixed in the first slot through bearings. Both ends of the other first round rod are fixed in the second slot through bearings. Both sponges are arranged on the first round rod, and the adjacent ends of the two sponges are in contact with the tool. Both ends of the first belt are fixed on the two first round rods.

[0010] Through the above technical solution, by retracting the tool into the housing for placement, the tool can be protected and the risks generated during non-use can be avoided.

[0011] By setting scale lines on the tool, and the scale lines are distributed as line segments of different lengths and marked with scales, and the diameter degrees are marked beside the scales. It is possible to judge which length of scale line to use for cutting according to the diameter numbers of the two seedlings, making the adaptability of the housing higher during actual use.

[0012] Under the action of the cleaning mechanism, after the tool completes cutting, the plant mucus adhered to the surface of the tool can be scraped off, which can extend the service life of the tool.

[0013] As a further improvement of the above solution, the clamping mechanism includes an installation groove, a first spring, a limiting block, a limiting groove and a sliding unit. A plurality of installation grooves are symmetrically opened on the slider. One end of the first spring is welded to the installation groove, and the other end of the first spring is welded to the limiting block. A plurality of limiting grooves are equidistantly opened in the housing, and the limiting block can be inserted into the limiting groove.

[0014] Through the above technical solution, by inserting the limiting block into the limiting groove, the stability of the slider in the housing can be ensured. At the same time, with the elastic potential energy of the first spring, the stability of the limiting block inserted into the limiting groove can be further ensured. Ensure that it is more stable when using the tool to cut the rootstock stem and the tomato stem.

[0015] As a further improvement of the above solution, the sliding unit includes a moving block and a slideway. Both moving blocks are fixed on the limiting block. Both slideways are opened in the installation groove, and the moving block slides in the slideway.

[0016] Through the above technical solution, when the inner wall of the housing presses the limiting block, the moving block slides in the slideway to ensure the horizontality of the movement of the limiting block, making the slider move more smoothly in the housing.

[0017] As a further improvement of the above scheme, the driving unit includes a belt 2, a round rod 2, a gear and a moving unit, both ends of the round rod 2 are fixed in the slot 1 through bearings, the gear is fixed on the round rod 2, and the two ends of the belt 2 are respectively arranged on one of the round rods 1 and 2 to drive the two in linkage.

[0018] Through the above technical solution, when the round rod 2 rotates, it drives the round rod 1 to rotate under the connection of the belt 2, and the other round rod 1 is also driven to rotate under the connection of the belt 1. Therefore, both sponges rotate, so that the side of the sponge just used to wipe the tool rotates to the side, ensuring that the tool will not be in contact, so as to prevent re-contamination.

[0019] As a further improvement of the above scheme, the moving unit includes a hinged rod, a second spring and an arc block, one end of each of the hinged rods is hinged on a slider and is located between two limit blocks, one end of the arc block is fixed on the slider next to the hinged rod, and the other end of the arc block can contact the hinged rod, one end of the second spring is fixed to the hinged rod, and the other end of the second spring is fixed to the slider.

[0020] Through the above technical solution, when the slider drives the hinged rod to go deeper into the shell, the hinged rod contacts the gear, which makes the hinged rod contact the arc block, driving the gear to rotate, thereby rotating the two sponges so that a new side contacts the tool. At the same time, the sponge and the round rod are glued together, and when the sponge rotates a circle, the sponge can be removed and a new sponge can be glued.

[0021] As a further improvement of the above scheme, a pushing mechanism is further provided at both ends of the slider, and the pushing mechanism includes a guide groove and a pinching plate. The two guide grooves are both opened on the outer shell and located above the limit groove. One end of the two pinching plates is fixed on the slider, and the other end of the pinching plate extends from the guide groove and is located outside the outer shell for workers to pinch.

[0022] Through the above technical solution, by providing arcs on the opposite sides of the two pinching plates, the friction between the pinching plates and the fingers can be increased, so that the worker can be more stable when pinching the pinching plates to push the slider to move.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] The utility model can select a suitable scale line according to the diameters of the rootstock stem and the tomato stem for matching under the action of the clamping mechanism, and then cut the rootstock stem and the tomato stem according to the length of the scale line. This can prevent, to the greatest extent, the situation of cutting them in half or having different cutting lengths. At the same time, under the action of the cleaning mechanism, it can clean the tool after cutting, extending the service life and enhancing the cleanliness of the tool during the next cutting.

[0034] Next, in combination with the drawings and the specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0035] Example 1:

[0036] Please combine Figures 1-7 For an adjustable tomato grafting cutting device in this embodiment, it includes a housing 1. A slider 3 is provided in the housing 1 through a clamping mechanism, and a cutter 2 is fixed on the slider 3. The cutter 2 can penetrate through the housing 1 for cutting operations;

[0037] Scale lines 16 are distributed on the cutter 2 for use as cutting scale marks;

[0038] A cleaning mechanism includes a first slot 12, two first round rods 13, two sponges 14, a first belt 15 and a driving unit. The first slot 12 is opened in the housing 1. A second slot is opened on the inner wall of the housing 1 below the first slot 12. Both ends of one of the first round rods 13 are fixed in the first slot 12 through bearings, and both ends of the other first round rod 13 are fixed in the second slot through bearings. Both sponges 14 are arranged on the first round rod 13, and adjacent ends of the two sponges 14 are in contact with the cutter 2. Both ends of the first belt 15 are fixed on the two first round rods 13.

[0039] The clamping mechanism includes an installation groove 4, a first spring 5, a limiting block 6, a limiting groove 7 and a sliding unit. A plurality of installation grooves 4 are symmetrically opened on the slider 3. One end of the first spring 5 is welded to the installation groove 4, and the other end of the first spring 5 is welded to the limiting block 6. A plurality of limiting grooves 7 are equidistantly opened in the housing 1, and the limiting block 6 can be inserted into the limiting groove 7.

[0040] The sliding unit includes a moving block 8 and a slideway 9. Both moving blocks 8 are fixed on the limiting block 6. Both slideways 9 are opened in the installation groove 4, and the moving block 8 slides in the slideway 9.

[0041] Both ends of the slider 3 are also provided with a pushing mechanism. The pushing mechanism includes a guiding groove 10 and a pinch plate 11. Both guiding grooves 10 are opened on the housing 1 and are located above the limiting groove 7. One end of both pinch plates 11 is fixed on the slider 3, and the other end of the pinch plate 11 extends out of the guiding groove 10 and is located outside the housing 1 for workers to hold.

[0042] In the embodiment of the present application, the implementation principle of an adjustable tomato grafting cutting device is as follows: When grafting is required, hold the outer shell 1 with the palm, and the index finger and thumb are respectively in contact with the two pinch plates 11. Push the slider 3 out of the outer shell 1, so that multiple limit blocks 6 are moved out of the limit groove 7, and the inner wall of the outer shell 1 presses the limit blocks 6 into the installation groove 4, so that the moving block 8 slides in the slideway 9, compressing the first spring 5, and the cutter 2 gradually moves out of the outer shell 1. When the limit block 6 moves to the adjacent limit groove 7, the first spring 5 rebounds and pushes the limit block 6 to be inserted into the limit groove 7, and the moving block 8 slides back to its original position in the slideway 9. Push the pinch plate 11 continuously in turn. According to the diameters of the existing rootstock stem and tomato stem, control the size of the scale line 16 that moves out of the outer shell 1. When the length of the scale line 16 that the cutter 2 moves out of the outer shell 1 is appropriate, stop pushing the pinch plate 11, so that multiple limit blocks 6 are inserted into the limit groove 7. Then pick up the rootstock stem and tomato stem respectively, control the inclination angle, align the appropriate scale line 16 with the rootstock stem and tomato stem. When cutting, make the scale line 16 just sink into the rootstock stem and tomato stem, then take out the cutter 2, and then fit the cut surfaces on the rootstock stem and tomato stem together and clamp them with a grafting clip.

[0043] Embodiment 2:

[0044] Combined with Figures 1-7 , on the basis of Embodiment 1, the further improvement of this embodiment is that the driving unit includes a second belt 17, a second round rod 18, a gear 19 and a moving unit. Both ends of the second round rod 18 are fixed in the first slot 12 through bearings, the gear 19 is fixed on the second round rod 18, and both ends of the second belt 17 are respectively arranged on one of the first round rod 13 and the second round rod 18 to drive the two to be linked.

[0045] The moving unit includes a hinge rod 20, a second spring 21 and an arc block 22. One ends of multiple hinge rods 20 are hinged on the slider 3 and are located between two limit blocks 6. One end of the arc block 22 is fixed on the slider 3 beside the hinge rod 20, and the other end of the arc block 22 can contact the hinge rod 20. One end of the second spring 21 is fixed to the hinge rod 20, and the other end of the second spring 21 is fixed to the slider 3.

[0046] In the embodiment of the present application, the implementation principle of an adjustable tomato grafting cutting device is as follows: After the grafting cutting is completed, pushing the two pinch plates 11 drives the tool 2 back into the housing 1. During this process, the two sponges 14 will adhere to the tool 2. Along with the movement of the tool 2, the mucus adhered to the surface of the tool 2 during cutting is scraped off. When the tool 2 is almost completely inside the housing 1, the slider 3 reaches below the gear 19, and the hinge rod 20 will contact the gear 19. Along with the continuous penetration of the slider 3 into the housing 1, the hinge rod 20 will be rotated towards the arc block 22, stretching the second spring 21. When the hinge rod 20 fits with the arc block 22, the hinge rod 20 will drive the gear 19 to rotate. The gear 19 drives the second round rod 18 to rotate. Under the linkage of the second belt 17, one of the first round rods 13 rotates. Under the connection of the first belt 15, the other first round rod 13 is also driven to rotate, driving the two sponges 14 to rotate, so that a new side of the sponge 14 contacts the tool 2.

[0047] When pushing the pinch plate 11 to move the tool 2 out of the housing 1, the gear 19 will press the hinge rod 20 towards the second spring 21, so that the hinge rod 20 moves out of the gap between the gear 19 and the slider 3 and cannot drive the gear 19 to rotate, enabling the two sponges 14 to clean the tool 2 again.

[0048] The above-mentioned implementation manner is only the preferred implementation manner of the present invention, and the protection scope of the present invention cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
