Description

Technical Field

[0001] The present application relates to the technical field of sugarcane seedling cutting equipment, and in particular to a seed bud jet cutting device and a cutting method for sugarcane tissue culture seedling production. Background Art

[0002] Sugarcane is an important cash crop and the most important sugar crop in the world. It is widely planted in tropical and subtropical regions. More than 100 countries in the world produce sugarcane, and the largest sugarcane producers are Brazil, India and China. As a major sugarcane-growing country in the world, my country's Taiwan, Fujian, Guangdong, Hainan, Guangxi, Sichuan, Yunnan and other southern tropical regions widely grow sugarcane, mainly for sugar production. The development of the sugarcane sugar industry has promoted the improvement of the sugar production system and the development of the sugar industry, machinery manufacturing industry and automobile transportation industry. At the same time, the development of the sugarcane industry has formed leading enterprises in social and economic development, opened up a market economy of production, supply and sales, which in turn promoted the development of the processing industry of agriculture, forestry and animal husbandry products. The development of the sugarcane industry has promoted the great development of the food industry, and the development of the food industry has promoted the prosperity of the market, increased consumption, stimulated domestic demand and promoted the development of the national economy.

[0003] Sugarcane is highly heterozygous, and its sexual offspring will undergo extensive separation. Asexual reproduction is the main method of reproduction, but its large seed volume, long growth time and slow reproduction rate have greatly limited the promotion and application of new varieties.

[0004] Sugarcane tissue culture seedling technology is a method of obtaining a large number of sugarcane seedlings with high genetic purity quickly and efficiently through sugarcane tissue culture, regeneration and reproduction. This technology can use the sugarcane plant to autonomously divide or regenerate new plants, greatly increasing the speed of sugarcane reproduction. Sugarcane tissue culture seedling technology has the advantages of rapid growth, disease-free, and stable quality. The process is to collect the young and tender tissues of sugarcane, such as stem segments, buds or leaves, and then pre-disinfect the surface to ensure that disease-free tissue culture seedlings are obtained. Through tissue culture technology, disease-free sugarcane seedlings can be reproduced in large quantities, improving the yield and quality of sugarcane seedlings.

[0005] At present, the cutting of sugarcane buds is still mainly done by traditional manual labor. Sugarcane seeds are produced by knives or simple machines. Long-term high-intensity cutting of sugarcane buds can easily cause muscle strain and lead to a series of health problems. Manual cutting is prone to uneven cutting or miscutting, resulting in waste of raw materials.

[0031] like Figures 1 to 3As shown, the seed bud jet cutting device for sugarcane tissue culture seedling production of this embodiment includes: a base assembly 10, a clamping assembly 20 and a cutting and disinfecting assembly 30. The base assembly 10 includes a base frame structure 11 and a workbench 12, and the workbench 12 is arranged on the base frame structure 11. The clamping assembly 20 includes a first clamping arm structure 21 and a second clamping arm structure 22, and the first clamping arm structure 21 and the second clamping arm structure 22 are movably arranged on the workbench 12, and the first clamping arm structure 21 and the second clamping arm structure 22 have clamping positions close to each other, or to-be-clamped positions far away from each other. The cutting and disinfection assembly 30 includes a jet frame structure 31, a cutting liquid tank structure 32, a cutting pump structure 33 and a cutting nozzle structure 34. The jet frame structure 31 and the cutting liquid tank structure 32 are arranged on the base assembly 10. The cutting pump structure 33 is connected to the inside of the cutting liquid tank structure. The cutting nozzle structure 34 is connected to the cutting pump structure 33 through a disinfectant pipeline and is arranged corresponding to the workbench 12. The cutting liquid tank structure has a space for holding disinfectant and an abrasive space.

[0032] By applying the technical solution of this embodiment, when the seed buds produced by sugarcane tissue culture seedlings are automatically cut, the sugarcane to be cut is first placed on the workbench, and the sugarcane to be cut is clamped and fixed by the first clamping arm structure and the second clamping arm structure. The cutting and disinfection component cuts the sugarcane to be cut by a mixed fluid of high-pressure liquid and abrasive. In this way, when the sugarcane to be cut is cut by a high-speed fluid, the disinfection process is also completed at the same time. In this way, cutting and disinfection are carried out at the same time, avoiding the spread of sugarcane viruses. In addition, according to the structure of sugarcane itself, the cutting effect is better through the mixing of disinfectant and abrasive, and there will be no fiber adhesion and no cutting. Moreover, the mixing of disinfectant and abrasive has a better effect on the disinfectant coating on the cutting surface of the cut sugarcane. The technical solution of this embodiment effectively solves the problem that the labor intensity of sugarcane tissue culture seed bud cutting work in the prior art is high and it is easy to cause the spread of sugarcane viruses.

[0033] In the technical solution of this embodiment, the cutting liquid tank structure 32 includes a disinfectant tank and an abrasive tank, the discharge port of the abrasive tank is located at the bottom, and the discharge port of the abrasive tank and the disinfectant pipeline are both connected to the cutting nozzle structure 34. In this way, the abrasive can flow out under the action of gravity. In addition, the Bernoulli equation principle of the fluid exerts a force on the abrasive, that is, the fluid pump can provide power for the abrasive through the negative pressure of the fluid. It should be noted that an abrasive control valve is provided on the abrasive pipeline, and a cutting control valve is provided on the disinfectant pipeline.

[0034] In the technical solution of this embodiment, the cutting nozzle structure 34 includes a mixing chamber section, a contraction section and an injection section from back to front. A section of the mixing chamber section away from the contraction section has a disinfectant inlet, and the side wall of the mixing chamber section is provided with an abrasive inlet, and the axis of the abrasive inlet is arranged at an acute angle to the axis of the disinfectant inlet. The mixing chamber section allows the fluid and the abrasive to be fully mixed and evenly mixed, and then the mixture of the disinfectant and the abrasive is sprayed out through the injection section. The axis of the abrasive inlet is arranged at an acute angle to the axis of the disinfectant inlet, so that the abrasive has forward kinetic energy when it flows out.

[0035] In the technical solution of this embodiment, the inner diameter of the disinfectant inlet is d1, the inner diameter of the mixing chamber section is d2, the inner diameter of the injection section is d3, d2 is 4 to 5 times of d1, d3 is 1.2 to 2 times of d1, and the length of the contraction section is 0.6 to 0.8 of the length of the mixing chamber section. The above structure is conducive to saving energy, as follows:

[0036] The flow of fluid in and out of the nozzle is a turbulent motion with a very high Reynolds number, which must comply with the mass conservation equation, momentum conservation equation and turbulent transport equation. The mass conservation equation is

[0037]

[0038] The momentum conservation equations in the x, y and z directions are:

[0039]

[0040] Where: ρ is density; t is time; u is velocity vector; u, v, w are the components of velocity vector in x, y and z directions; div is divergence, that is p is pressure; τ xx , τ xy and τ xz is the component of viscous stress τ; F x 、F y and F z is the body force. If the body force is only gravity and the z-axis is vertically upward, then F x =0, F y =0, F z =ρg.

[0041] The control equation of turbulence adopts the Realizable k-e equation, and the equations of turbulent kinetic energy k and dissipation rate ε are:

[0042]

[0043]

[0044] Where u i Speed: x i 、x jis the coordinate; μ is the molecular viscosity; μ t is the turbulent viscosity; G k is the turbulent kinetic energy caused by the mean velocity gradient; G b is the kinetic energy caused by the buoyancy effect; Y M is the pulsation expansion term in compressible turbulence; C 1ε , C 2ε , C 3ε is the empirical constant, C 1ε =1.44, C 2ε =1.92, C 3ε =0.09;σ k , σ ε The Prandtl number corresponding to the turbulent kinetic energy and dissipation rate, σ k =1.3,σ ε =1.0.

[0045] The kinetic energy of the abrasive particles can be regarded as Where m is the mass of the abrasive particles, v1 is the velocity of the abrasive particles, usually the inlet velocity of the abrasive is 10m / s, the jet outlet is a pressure outlet, and the outlet pressure is standard atmospheric pressure.

[0046] Combining the energy conservation equation of the fluid and the kinetic energy of the abrasive particles and the sugarcane cutting force of 32N, the above dimensions of the cutting nozzle structure 34 and the cutting speed of the mixture of fluid and abrasive are calculated to be between 450m / s and 600m / s.

[0047] In the technical solution of this embodiment, the cutting and disinfecting assembly 30 further includes a cutting nozzle walking structure 35, which is movably arranged on the jet frame structure 31, and the cutting nozzle structure 34 is arranged on the cutting nozzle walking structure 35. The arrangement of the cutting nozzle walking structure 35 facilitates the movement of the jet cutting device.

[0048] In the technical solution of this embodiment, the cutting nozzle walking structure 35 includes a walking motor, a driving sprocket, a driven sprocket and an annular sprocket. The walking motor is arranged on the jet frame structure 31. The driving sprocket is connected to the output end of the walking motor. The annular sprocket is adaptively arranged on the circumferential outer side of the driving sprocket and the driven sprocket. The cutting nozzle structure 34 is connected to the annular sprocket. The distance between the driven sprocket and the driving sprocket can be fine-tuned, and the moving direction of the annular sprocket is perpendicular to the axis direction of the sugarcane.

[0049] In the technical solution of this embodiment, the workbench 12 has a cutting slit, and the extension direction of the cutting slit is consistent with the moving direction of the cutting nozzle structure 34. This avoids the large force of splashing liquid and abrasive during cutting.

[0050] In the technical solution of this embodiment, the base assembly also includes a protective cover structure, and the protective cover structure is arranged on the circumferential outer side of the cutting nozzle structure 34. The protective cover structure can effectively protect the staff from injury and save resources. It should be noted that a sugarcane seedling (seed bud) receiving frame is provided at the lower part of the workbench 12, and a waste liquid collection tank is provided below the receiving frame. A filter screen is provided at the upper part of the collection tank, and the abrasive is trapped on the filter screen and can be recycled. A recovery pump is provided in the waste liquid collection tank, and the recovery pump is connected to the cutting liquid tank structure 32. It should be noted that the protective cover structure includes glass material and can be moved to open or close.

[0051] According to another aspect of the present application, a seed bud jet cutting method for producing sugarcane tissue culture seedlings is also provided. The jet cutting method uses the above-mentioned jet cutting device, and the jet cutting method comprises:

[0052] S10 places the sugarcane to be cut and clamps the sugarcane to be cut;

[0053] S20 starts the cutting and disinfecting assembly 30 to cut the sugarcane to be cut by a mixture of disinfectant and abrasive;

[0054] S30 The cutting is completed, and the cutting and disinfecting assembly 30 returns to its original position.

[0055] From the above, it can be seen that the cutting method used by the jet cutting device is high-pressure water jet cutting. The cutting liquid of the device is a variety of agents, including Bordeaux mixture, copper hydroxide, and thiophanate. Using a variety of liquid medicines as cutting liquids can disinfect the wound while cutting the sugarcane tissue culture seedlings, greatly improving the cutting and disinfection efficiency of the sugarcane tissue culture seedlings. Different types of abrasives are used in the abrasive tank in the above device, including: modified heavy calcium carbonate powder (particle size: 80-1200 mesh), quartz powder (particle size: 80-1200 mesh), and wollastonite (particle size: 80-1200 mesh). The liquid medicine (disinfectant or cutting liquid) is mixed with the abrasive and ejected from the nozzle to complete the cutting work.

[0056] The device is designed with an image recognition system, and the system can recognize nine different types of sugarcane tissue culture seedlings. When the camera recognizes the sugarcane tissue culture seedlings, the sugarcane tissue culture seedlings will be moved and positioned so that the size of the cut sugarcane seedlings is controlled within the set range, thus realizing automatic cutting of sugarcane tissue culture seedlings.
