Description

Technical Field

[0001] The present invention relates to the technical field of agricultural equipment, and particularly to a seed sowing pretreatment device. Background Art

[0002] Seeds for agricultural sowing usually need to be subjected to some pretreatment operations before sowing to improve the germination rate and emergence uniformity of the seeds. The common operation methods include dry mixing (suitable for mixing with powder or wettable powder), wet mixing (suitable for mixing with liquid medicine), and seed coating (using a seed coating machine or manual method for coating). Most of the above operation methods are carried out by manual or seed mixer.

[0003] For example, the invention patent with the authorized patent publication number of CN118414940B in China discloses a seed mixing pretreatment device for soybean seed sowing. The pretreatment device uses a soft brush to dip the seed dressing agent and then collides with the soybean seeds to coat the seed dressing agent on the surface of the soybean seeds to achieve the purpose of mixing the soybean seeds with the seed dressing agent, and can also avoid damage to the epidermis of the soybean seeds.

[0004] However, this coating method is likely to cause uneven coverage of the medicine on the seed surface due to the rotation or deviation of the seeds. The thick part of the medicine film may inhibit seed germination, reduce the germination rate of the seeds, extend the germination time, and even cause seed rot. In the places where the medicine film is thin or missing, the seeds are not sufficiently protected, are easily affected by pests and diseases in the initial growth stage, have weak growth potential, and affect the quality and yield of the seedlings.

[0036] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 to 10 , the present invention provides a technical solution: A seed sowing pretreatment device includes a processing cylinder 1, and further includes:

[0038] A vertical pipe 3 fixed to the top opening of the processing cylinder 1 through a conical barrel 2, and a feeding channel is formed in the vertical pipe 3;

[0039] A feed pipe 6 connected to the upper side wall of the vertical pipe 3, and the feed pipe 6 is used to slide the seeds into the drop channel;

[0040] A steam inlet pipe 7 connected to the side wall below the vertical pipe 3 is connected to an external fogging device and sprays water mist into the material dropping channel;

[0041] An air jet assembly sprays air upward from the bottom of the blanking channel, so that the water mist fills the blanking channel and guides the water mist to flow upward;

[0042] A seed mixing cylinder 12 is arranged in the processing cylinder 1 and is used for containing a dry powder seed dressing agent. A stirring member is arranged in the seed mixing cylinder 12, and the stirring member is used for stirring the fallen seeds and the seed mixing agent.

[0043] When the seed sowing pretreatment device is in use, water mist is firstly generated through an external fogging device, and enters the blanking channel through the steam inlet pipe 7. At the same time, the jet assembly jets upward from the bottom of the blanking channel, so that the water mist fills the blanking channel and guides the water mist to flow upward, creating an atomized space in the blanking channel, and then the selected seeds are slid into the blanking channel through the feed pipe 6 and pass through the water mist, so that the fine moisture in the water mist adheres to the epidermis of the seeds to form a fine water film, and after the seeds fall into the seed mixing barrel 12, the stirring of the stirring member allows the seed dressing agent to adhere to the surface of the seeds, thereby forming a uniform drug film, and completing the seed mixing process;

[0044] During this process, it is worth mentioning that since the atomized water mist will adhere to the seed epidermis in the form of extremely fine water mist particles, it can form a water film on the seed surface. By combining the water film with dry powder, a drug film that is not easy to fall off is formed on the seed surface, thereby improving the adhesion of the drug film. It can also have a certain moisturizing effect on the seed epidermis, improve the flexibility of the seed coat, and avoid the rupture of the seed coat when the stirring element stirs the seeds in the subsequent process, thereby improving the yield rate of seed mixing and further ensuring the yield and quality of crops.

[0045] It is also worth noting that the fog-making equipment uses ultrasonic waves to form water mist, which is similar to the principle of a humidifier. The temperature of the water mist will not be too high, thus avoiding affecting the seeds. The intensity of the water mist can also be controlled to control the thickness of the water film on the surface of the seeds, thereby controlling the thickness of the agent on the seed surface after mixing and improving the quality of seed mixing.

[0046] In one of the more preferred embodiments, an implementation of a stirring member is provided;

[0047] The stirring member includes a connecting pipe 29 installed through the bottom of the center of the seed mixing barrel 12, and the connecting pipe 29 is driven to rotate by an external structure. The inner wall of the vertical pipe 3 is fixed with an empty pipe 15 through a bracket. The empty pipe 15 is inserted into the connecting pipe 29 and is rotatably connected thereto. The outer wall of the empty pipe 15 is installed with a lifting sleeve 17 that can be vertically slidably adjusted, and the outer wall of the empty pipe 15 located below the lifting sleeve 17 is also sleeved with a mounting ring 18, and the lifting sleeve 17 and the mounting ring 18 are rotatably connected. A sleeve ring 32 is rotatably installed at the top opening of the seed mixing barrel 12, and an elastic net 16 is commonly connected between the sleeve ring 32 and the mounting ring 18. The mounting ring 18 and the connecting pipe 29 are opposite to each other. The ends are provided with convex teeth that can mesh with each other.

[0048] For details, please refer to Figure 4 After the seeds covered with the water film fall from the drop channel, they will first fall on the elastic net 16, which can play a certain buffering role. Then, driven by the external structure, the lifting sleeve 17 moves downward and drives the mounting ring 18 to move downward together. At this time, the elastic net 16 will be stretched under the pulling effect and cut into the seed dressing agent below, so that the seeds are in contact with the seed dressing agent. Figure 8 In the state shown, at the same time, the bottom end of the mounting ring 18 also contacts the top end of the connecting tube 29, and the convex teeth therebetween mesh with each other. Then, driven by the external structure, the connecting tube 29 drives the mounting ring 18 to rotate together, and then the mounting ring 18 drives the elastic net 16 and the sleeve ring 32 to rotate together, thereby stirring the seed dressing agent, so that it can be fully mixed and stirred with the seeds, so that the agent can evenly cover the surface of the seeds to form a drug film;

[0049] It is worth mentioning that since the seed dressing agent is stirred from the bottom layer of the seed dressing agent through the stirring of the elastic net 16, it is equivalent to not having a relatively hard contact with the seeds. In addition, the elastic effect of the elastic net 16 itself will make the stirring of the seeds and the seed dressing agent relatively gentle, so as not to cause damage to the seed epidermis as much as possible. While ensuring the integrity of the seed coat, the seeds can still be mixed evenly, further improving the quality of the seed dressing.

[0050] After the seed dressing is finished, the lifting sleeve 17 is driven upward by the external structure, and the elastic net 16 is pulled upward by the mounting ring 18 to form an upward cone shape, that is, Figure 9 As shown, this can not only separate the seeds from the seed dressing agent, but also the formed conical surface makes it easier for the seeds to slide down from the edge for collection;

[0051] Furthermore, an annular channel 13 is fixed on the outer wall of the seed mixing cylinder 12 . The annular channel 13 is designed to be inclined, and a discharge port extending out of the processing cylinder 1 is connected to the lowest point.

[0052] See also Figure 3, the seeds that slide down will fall into the surrounding annular channel 13, and then be discharged outside the treatment cylinder 1 from the discharge port, completing the pre-treatment process of seed dressing;

[0053] In this way, through the intermittent up and down adjustment of the lifting sleeve 17, the state of the elastic net 16 is changed, so that it can be switched between a plane, a concave conical surface and a convex conical surface, thus completing the whole process of seed dressing pre-treatment, not only improving the dressing quality, but also ensuring the integrity of the seed epidermis.

[0054] Moreover, it is worth mentioning that stirring rods can also be installed on the outer wall of the connecting pipe 29, so that the connecting pipe 29 can continuously stir the dressing agent during rotation to prevent the powdery dressing agent from coagulating or caking together.

[0055] In one relatively preferred embodiment, an implementation manner of a jet component is provided;

[0056] The jet component includes a chassis 24 fixed between the inner bottoms of the dressing cylinder 12 and the treatment cylinder 1. An eccentric cavity 25 is opened inside the chassis 24. A piston box 26 coaxially designed with the chassis 24 is rotatably installed in the eccentric cavity 25. The bottom of the piston box 26 is connected with a driving pipe 30 passing through the bottom of the treatment cylinder 1, and the driving pipe 30 is driven by a motor. The bottom end of the connecting pipe 29 penetrates into the eccentric cavity 25 and is communicated with the inside of the piston box 26. A piston block 27 is slidably installed inside the piston box 26, and a piston rod 28 is fixedly penetrated through the piston block 27. The two ends of the piston rod 28 respectively penetrate out from both sides of the piston box 26 and can intermittently contact the inner wall of the eccentric cavity 25. The empty pipe 15 is hollow and has an opening at the top. One-way valves are installed on the inner walls of the driving pipe 30 and the connecting pipe 29, and an air inlet is also opened on the outer wall of the driving pipe 30.

[0057] Specifically, refer to Figure 3 - Figure 5 , during the process of seed dressing, the motor drives the piston box 26 to rotate through the driving pipe 30, thereby driving the connecting pipe 29 to rotate together. During the rotation, since the rotation axis of the piston box 26 is eccentrically designed with respect to the eccentric cavity 25, the piston rod 28 will alternately contact the inner wall of the eccentric cavity 25 during the rotation of the piston box 26, thereby driving the piston block 27 to reciprocate inside the piston box 26. Then, air is inhaled through the air inlet of the driving pipe 30 due to the change of the internal air pressure, and then discharged through the connecting pipe 29 and ejected from the opening at the top of the empty pipe 15, thereby achieving the purpose of jetting air upward from below the blanking channel;

[0058] Moreover, since the moving stroke of the piston block 27 in the piston box 26 exceeds the axis position of the drive pipe 30, the spaces on both sides of the piston box 26 can alternately inhale and exhale air, so that the air flow ejected upward from the empty pipe 15 can form a relatively continuous air flow, avoiding the sinking of water mist caused by the interruption of the air flow.

[0059] In one relatively preferred embodiment, an implementation manner for treating the condensed water in the blanking channel is provided;

[0060] A blanking pipe 11 is fixed to the inner wall of the vertical pipe 3 through a bracket, and there is a gap between the blanking pipe 11 and the vertical pipe 3. Both the feed pipe 6 and the steam inlet pipe 7 penetrate into the blanking pipe 11. The top opening of the vertical pipe 3 is connected to a discharge pipe 4 through a condensation elbow 5. A liquid collecting ring 14 is also fixed to the inner wall of the vertical pipe 3 below the blanking pipe 11, and the liquid collecting ring 14 wraps the bottom of the blanking pipe 11. A drain pipe 8 is also communicated with the side wall of the vertical pipe 3.

[0061] Specifically, refer to Figure 3 , when the water mist enters the blanking pipe 11 and flows upward as the gas rises, it will contact the inner wall thereof and condense into liquid beads. After the liquid beads slide down from the inner wall of the blanking pipe 11 into the lower seed dressing cylinder 12, the seed dressing agent will agglomerate, thus affecting the subsequent seed dressing. Therefore, it is necessary to collect and treat the condensed liquid;

[0062] By installing the liquid collecting ring 14 below the blanking pipe 11, the liquid beads sliding down from the blanking pipe 11 can be collected and discharged through the drain pipe 8, avoiding affecting the seed dressing agent below. Moreover, the design of the condensation elbow 5 can also have a concentrated effect on the condensation of the water mist. After the water mist hits the inner wall of the condensation elbow 5, it will condense more concentratedly and slide into the liquid collecting ring 14 from the gap between the vertical pipe 3 and the blanking pipe 11. The discharged condensed water can be reused to reduce water waste.

[0063] In one relatively preferred embodiment, an implementation manner for further improving the water film uniformity of seeds in the atomization space is provided;

[0064] At the inner bottom of the opening of the feed pipe 6 located in the blanking pipe 11, there are convex ridges 31, and an air delivery pipe 10 is also connected in the gap between the convex ridges 31. The air inlet end of the air delivery pipe 10 penetrates into the treatment cylinder 1 and the chassis 24 and is communicated with the eccentric cavity 25. One-way air outlets are provided on both side walls of the piston box 26.

[0065] Specifically, refer to Figure 6, it can be known from the above content that the piston box 26 will continuously squeeze air into the empty tube 15 when it rotates, and one-way air outlets are provided on both side walls of the piston box 26, so that the air can be squeezed into the eccentric cavity 25 while entering the empty tube 15, and the air in the eccentric cavity 25 will enter the feed pipe 6 through the air pipe 10 under the action of the increased internal air pressure, and then enter the drop pipe 11, and due to the design of the convex ridge 31, it will play a supporting role when the seeds slide down from the feed pipe 6, and provide an upwardly jumping inclined surface, and in conjunction with the action of the airflow of the air pipe 10, the seeds will fall in a rotating state when entering the drop pipe 11, so that the rotation of the seeds can not only increase the contact time and area with the water mist, so that the water absorption of the seed coat surface is better, but also through the centrifugal effect of its rotation, the excess water droplets attached to the seeds can be thrown out or evenly thrown, further improving the uniformity of the water film on the seed coat surface, providing a guarantee for the subsequent improvement of the seed mixing quality.

[0066] In one of the more preferred embodiments, two groups of annular grooves 19 are opened on the lower inner wall of the lifting sleeve 17, and an annular protrusion 20 is formed on the top outer wall of the mounting ring 18. The annular protrusion 20 can rotate in the annular groove 19 and can also jump and cut between the two annular grooves 19.

[0067] When the seeds fall onto the elastic net 16 below, the moisture on the seeds will contact the elastic net 16 and inevitably be absorbed a little. Therefore, after the elastic net 16 is in contact with the seed dressing agent for a long time, the mesh opening of the elastic net 16 may be blocked, thereby reducing the passing rate of the dry powder and affecting the seed dressing effect.

[0068] Therefore, in this embodiment, when the teeth of the mounting ring 18 and the connecting tube 29 are meshed with each other, the annular protrusion 20 on the mounting ring 18 is located in the annular groove 19 below and rotates, as shown in FIG. Figure 7 As shown, as the mounting ring 18, the elastic net 16 and the collar 32 rotate together, the collar 32 will gradually expand due to friction, thereby increasing the friction between it and the seed dressing barrel 12, so that the friction between the teeth of the mounting ring 18 and the connecting tube 29 that mesh with each other will also increase accordingly, see Figure 10 , the edges of the teeth of the two are set to be rounded, so that when the friction between the two cannot overcome the friction between the ring 32 and the seed mixing tube 12, the installation ring 18 and the connecting tube 29 will be staggered, and at the same time, the connecting tube 29 will push the installation ring 18 upward, so that the annular protrusion 20 jumps and cuts into the annular groove 19 above, and the two are separated. At this time, the seeds can be separated by moving the lifting sleeve 17 upward;

[0069] During this process, as the ring 32 heats up and the friction between the seed mixing barrel 12 increases, the ring 32 and the mounting ring 18 will rotate relative to each other, thereby further increasing the rotational pulling force of the elastic net 16, making it present a spiral pulling state. When the mounting ring 18 and the connecting tube 29 are staggered from each other, they will be reset under the rotational torsional force of the elastic net 16, and at the same time, the torsional force of the elastic net 16 will be released instantly, thereby shaking off the blocked blocks adhered to it, and unblocking the elastic net 16. In addition, the change in the shape of the orifice when the elastic net 16 is pulled can further improve its cleaning effect, thereby ensuring its patency after long-term use, and further ensuring the quality of seed mixing.

[0070] In one of the more preferred embodiments, an implementation method of driving the slider 22 to slide and adjust is provided;

[0071] A mounting tube 9 is fixed to the inner wall of the conical barrel 2, and a slider 22 is slidably installed in the mounting tube 9, a connecting rod 21 is rotatably installed between the slider 22 and the lifting sleeve 17, a screw 23 is rotatably installed on the inner wall of the mounting tube 9, the screw 23 penetrates the slider 22 and is threadedly connected to the penetration point of the slider 22, and a servo motor for driving the screw 23 to rotate is also installed on the outer wall of the mounting tube 9.

[0072] For details, please refer to Figures 2 - 3 The servo motor drives the screw 23, and the screw 23 cooperates with the slider 22 to achieve the purpose of controlling the sliding adjustment of the slider 22, and the lifting sleeve 17 is synchronously driven to slide and adjust in the vertical direction under the connection of the connecting rod 21.

[0073] In one of the more preferred embodiments, the inner wall of the condensation elbow 5 is configured as a curved arc surface, and the outer wall is connected to the refrigeration equipment.

[0074] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
