Description

Technical Field

[0001] The present invention relates to a lifting and handling device for agricultural production articles, and more specifically, to a special mobile lifting device used in conjunction with large-scale rice seedling production, mainly used in a seed pretreatment process before sowing, and belongs to the field of agricultural technology. Background Art

[0002] Rice is one of the most important food crops in the world. Before rice is planted and raised, the seeds need to be dried, selected, soaked, broken (germinated), and dried in the sun. These steps are time-consuming and there is a lot of rice seed transportation work between each step, which requires a lot of manpower.

[0003] The decrease in the absolute number of rural population and the deepening of aging have further reduced rural labor resources.

[0004] In addition, the seasonal nature of agricultural production makes the demand for labor very concentrated in certain periods, such as spring ploughing, summer harvest, and autumn planting, when the elderly and women become the main force in farming. Due to physical and mental limitations, these agricultural production workers find it difficult to undertake heavy agricultural labor, resulting in many agricultural techniques failing to meet the fine requirements, further affecting agricultural productivity, reducing grain yields per unit area, and reducing the quality of agricultural products.

[0005] For example, when soaking rice seeds, it is recommended to perform intermittent "seed soaking" and "seed exposure" treatments, which can greatly improve the germination potential and germination rate. The agronomic treatment process is as follows: put the rice seeds in a woven bag, put it in a container filled with clean water and soak it for 8 to 10 hours, take the rice seed bag out of the container and let it air-dry for 6 to 8 hours; at this time, after several hours of soaking, the pathogen spores attached to the seeds have germinated and need to be soaked in chemicals for sterilization. Put the rice seed bag in the chemical for soaking for 8 to 10 hours, then take it out, put it in clean water, rinse it, and ensure that there is no residual drug solution on the surface; then soak the rice seed bag in clean water for 8 to 10 hours, then take it out and let it air-dry for 6 to 8 hours; repeat several times; this process is affected by temperature and other environmental factors, and usually takes 2 days or longer.

[0006] In actual production, because the planting area of ​​large-scale rice production and operation entities such as farmers' professional cooperatives and family farms is at least 300 mu, more than 2,000 kilograms of rice seeds need to be soaked; and after the rice seeds absorb 25%-35% of water, the amount reaches more than 3,000 kilograms. According to the aforementioned standard agronomic requirements for seed soaking, nearly 100 kilograms of seed bags need to be lifted up and put down, and carried back and forth dozens of times, which is time-consuming and physically demanding. The elderly and women are too weak to bear it and cannot perform as required. They often soak the seeds casually, either for a long time, causing the nutrients to overflow and causing internal rot (manifested as odor and fermentation), or the soaking time is too short, and the seeds cannot fully absorb water, affecting the germination effect.

[0007] “Good seedlings mean half a year’s grain, good seedlings mean 80% of the grain”, seed treatment has an inseparable relationship with the growth and development of crops and the yield level; in the current context of increasing shortage of young and strong labor in rural areas, large-scale rice seedling production requires a lifting and handling device that saves labor and effort, is easy to disassemble and transport, and has low cost.

[0008] At present, there is no special mobile lifting equipment for the pre-treatment process of rice seeds before sowing; rice seedling greenhouses are generally built on basic farmland, and the greenhouse structure must be easy to dismantle and restore the original state of the land. Permanent buildings cannot be built, and hardened ground is not allowed. Therefore, conventional large-scale mobile lifting equipment, such as traveling cranes, are limited by the space and structure of the greenhouse and are inconvenient to install and fix; small lifting equipment, such as hand-pulled (or electric) hoists, etc., are slow and time-consuming, because "the same time period is different at different work points, and the same work point is different at different time periods" In order to meet the lifting needs, the hand (or electric) hoist must be moved back and forth continuously to change its position. On non-hardened ground, the hand (or electric) hoist is inconvenient to move and requires multiple people to carry it, which is even more troublesome. If a fixed lifting equipment hand hoist is arranged at each work point, the transfer of seeds and other materials still requires a lot of manpower, which not only wastes money and occupies site space, but also fails to achieve the purpose of saving labor and time. In addition, the seed processing operation time is less than 2 months each year, and the idle time is long. Therefore, the seed processing lifting device used should also be easy to disassemble and transport so that it can be used in other work locations and scenarios. Summary of the invention

[0045] like Figure 1 As shown, this embodiment provides a typical device and its working scene, and the typical working scene includes three seed processing containers (04); the seed processing container (04) can be a water tank or a common seed soaking facility such as a pool. In actual production, in order to facilitate manual placement and removal of seeds, the depth of the container is generally not more than 100CM; the schematic water tank of the embodiment is a rectangular parallelepiped with a length of 2.0M*width of 1.2M*height of 0.9M. A plurality of seed frames (05) can be placed in the seed processing container (04); the seed frames (05) are provided with a lifting ring or a lifting rope loop for quickly hanging a hook, so that the seed frames (05) can be quickly taken out of the seed processing container (04) and transported to other places.

[0046] The work area traveling frame (02) is placed above the edge of the seed processing container (04), the interval traveling frame (03) is placed on the short side of the seed processing container (04) and connected to the work area traveling frame (02), and the interval traveling frame (03) is connected to the interval traveling frames (03) of other workstations to form a whole.

[0053] The power supply and operation box (1-4) comprises: a battery pack (1-4-1), an indication control box (1-4-2), and a charging quick connector (1-4-3); The battery pack (1-4-1) is used to supply power to the electric push rod assembly (1-3-1) in the lifting mechanism box (1-3); the present embodiment adopts a 24V10A lithium battery for DC power supply. On the one hand, the DC motor is suitable for low-cost operation and has the advantages of high efficiency, less operation and maintenance, large starting torque of the DC motor, and fast response speed of "start, reverse and stop" actions, and is suitable for traction, lifting and other fields; on the other hand, the mobile hoist (01) has its own working power supply and does not require an external AC cable, which makes it more convenient to move and more adaptable to various agricultural production locations such as rural fields where power supply is inconvenient.

[0057] The pulley stroke amplification mechanism (1-3-2) comprises a right side hook (1-3-2-1), a right side rope (1-3-2-2), a right side rope-turning left fixed pulley (1-3-2-3), a right side rope-turning movable pulley (1-3-2-4), a right side rope-turning fixed seat (1-3-2-5), a left side hook (1-3-2-6), a left side rope (1-3-2-7), a left side rope-turning right fixed pulley (1-3-2-8), a left side rope-turning left fixed pulley (1-3-2-9), a left side rope-turning movable pulley ( 1-3-2-10), left side lifting rope fixing seat (1-3-2-11); one end of the right side lifting rope (1-3-2-2) is connected to the right side lifting hook (1-3-2-1), and the other end passes through the right side rope turning left fixed pulley (1-3-2-3), the right side rope turning movable pulley (1-3-2-4) and is connected to the right side lifting rope fixing seat (1-3-2-5); the right side rope turning left fixed pulley (1-3-2-3) is fixed to the middle upper position of the side of the rear frame fixing plate (1-3-3-1); the right side rope turning movable pulley (1- 3-2-4) is fixed to the top position of the side of the movable pulley fixing plate (1-3-1-4); the right side suspension rope fixing seat (1-3-2-5) is fixed to the top position of the side of the rear frame fixing plate (1-3-3-1); one end of the left side suspension rope (1-3-2-7) is connected to the left side suspension hook (1-3-2-6), and the other end passes through the left side rope turn right fixed pulley (1-3-2-8), the left side rope turn left fixed pulley (1-3-2-9), the left side suspension rope movable pulley (1-3-2-10) and the left side suspension rope fixing seat (1 -3-2-11) connection; the left rope turn right fixed pulley (1-3-2-9) is fixed on the front frame fixing plate (1-3-3-4); the left rope turn left fixed pulley (1-3-2-10) is fixed in the middle position of the middle frame fixing plate (1-3-3-3); the left suspension rope movable pulley (1-3-2-10) is fixed at the bottom position of the side of the movable pulley fixing plate (1-3-1-4); the left suspension rope fixing seat (1-3-2-5) is fixed in the middle upper position of the side of the push rod fixing plate (1-3-3-2).

[0058] The pulley block of this embodiment adopts 304 stainless steel U-shaped double bearing pulley; when the push rod telescopic section (1-3-1-2) of the electric push rod assembly (1-3-1) is extended or retracted, the pulley fixing plate (1-3-2-1) is pulled forward or backward, and the pulley fixing plate (1-3-2-1) is pulled forward or backward. Figure 4 The simple "movable pulley + changing fixed pulley combination" shown achieves a 2-fold stroke amplification, so that the maximum lifting stroke of the hook (1-3-2-3) is enlarged to 100~120CM; this mechanism is simple and light, reliable in operation and low in cost.

[0059] like Figure 6As shown, the work area walking frame (02) includes two guide rail frames (2-1); multiple connecting beams (2-2) and a blocking frame (2-3); the guide rail frame (2-1) includes a guide rail square tube (2-1-1) and a supporting foot column (2-1-2); the guide rail frame (2-1) includes a guide rail square tube (2-1-1) and a supporting foot column (2-1-2); during operation, the mobile hoist (01) is placed on the guide rail square tube (2-1-1) of the work area walking frame (02) and moves along the long side of the seed treatment container (04) (hereinafter referred to as lateral movement); the height of the guide rail frame (2-1) is slightly higher than the upper edge of the seed treatment container (04) by 5 to 10 cm. If the seed treatment container (04) is a pool below the ground, the guide rail frame (2-1) should be at least 25 cm above the ground. The connecting crossbeam (2-2) connects the two guide rail frames (2-1) to form a rectangular frame structure; the blocking frame (2-3) is installed at one end of the rectangular frame structure, and the other end of the rectangular frame structure is connected to the interval transfer frame (03).

[0060] like Figure 7 As shown, the interval transfer frame (03) can be divided into four types according to the placement position of the work area: the left transfer frame (3-1), the interval walking frame (3-2), the middle transfer frame (3-3), and the right transfer frame (3-4); the left transfer frame (3-1), the middle transfer frame (3-3), and the right transfer frame (3-4) are respectively connected to the work area walking frame (02) at the left position, the middle position, and the right position; the left transfer frame (3-1), the middle transfer frame (3-3), and the right transfer frame (3-4) are basically similar in structure, including: a transverse guide rail (3-1-1), a longitudinal guide rail (3-1-2), an anti-fall plate guide block (3-1-3), Corner protection frame (3-1-4), longitudinal side protection frame (3-1-5), longitudinal guide rail protection plate (3-1-6), anti-fall plate longitudinal support bar (3-1-7), transverse side protection frame (3-1-8), anti-fall plate transverse support bar (3-1-9); the interval walking frame (3-2) is used for the connection between the left transfer frame (3-1), the middle transfer frame (3-3), and the right transfer frame (3-4). The structure is relatively simple, eliminating the components such as "transverse guide rail (3-1-1), anti-fall plate guide block (3-1-3), corner protection frame (3-1-4), transverse side protection frame (3-1-8), anti-fall plate transverse support bar (3-1-9)".

[0061] The guide rail square tube (2-1-1) of the work area walking frame (02) is connected to the transverse guide rail (3-1-1) of the section transfer frame (03); the transverse guide rail (3-1-1) and the longitudinal guide rail (3-1-2) are perpendicularly intersected, and the longitudinal guide rail (3-1) of the section transfer frame (03) is connected to the longitudinal guide rail (3-1-2) of the adjacent section transfer frame (03); the longitudinal guide rail protection plate (3-1-6) is fixed to the outer side of the longitudinal guide rail (3-1-2); the anti-fall plate transverse support bar (3-1-9) is fixed to the outer side of the transverse guide rail (3-1-1); the anti-fall plate longitudinal support bar (3-1- 7) is fixed between the longitudinal guide rails (3-1-2), and its installation position is related to the position of the sliding anti-fall plate (1-5-1); the mobile hoist (01) can move horizontally from the walking frame (02) of any work area to the transverse guide rail (03-1) of the interval transfer frame (03), and then move longitudinally on the longitudinal guide rail (03-2) of the interval transfer frame (03) to the adjacent interval transfer frame (03), and then move longitudinally to the next interval transfer frame (03). After reaching the target work area, it moves horizontally from the interval transfer frame (03) to the working walking frame (03) of the target work area to perform operations.

[0062] The work area walking frame (02) and the interval transfer frame (03) are modularly designed. If the user's planting scale is large, the number of seed processing containers (04) is large or the distance is relatively far, it is only necessary to increase the work area walking frame (02), the interval walking frame (3-2) and the middle transfer frame (3-3) accordingly. This design is convenient for reducing the initial investment, the overall disassembly and assembly are flexible, the on-site adaptability is good, and the subsequent function expansion is convenient.

[0063] Considering the poor agricultural production environment, the guide rails of the work area walking frame (02) and the interval transfer frame (03) do not use grooved steel, so as to avoid soil and gravel accumulation and inconvenience in cleaning at any time, which affects the movement. The guide rails of the work area walking frame (02) and the interval transfer frame (03) are made of ordinary 40 square tubes or 40 angle irons. On the one hand, the track surface is easy to clean, and on the other hand, the material is cheap and easy to process (even directly cut and processed on the spot in the greenhouse); the work area walking frame (02) and the interval transfer frame (03) are connected to each other with bolts, which are quick to disassemble and easy to carry. After the rice seedling raising season, they can be transferred to other locations (scenes) for operation as needed, thereby improving the utilization rate of the equipment.

[0064] Since the guide rails of the work area walking frame (02) and the interval transfer frame (03) are flat, there is a risk of falling, tipping over, etc. when the mobile hoist (01) walks on the guide rails. The present invention designs a "sliding anti-falling plate (1-5-1), a button-type brake pin (1-5-2), a corner guide wheel (1-5-3)" and other limit positioning and guide components on the mobile hoist (01); and designs a "corner protection frame (3-1-4), a longitudinal side protection frame (3-1-5), a longitudinal guide rail protection plate (3-1-6), a lateral side protection frame (3-1-8)" and other safety frame components on the interval transfer frame (03). The limit positioning auxiliary components and the safety frame components provide the mobile hoist (01) with the functions of "walking guidance; safety protection against tipping over, falling, etc."

[0065] like Figure 8 As shown, the sliding anti-fall plate (1-5-1) is fixed on the outside of the universal wheel chassis (1-1); when the mobile hoist (01) walks on the work area walking frame (02), the left sliding anti-fall plate (1-5-1) fits on the outer side of the left guide rail square tube (2-1-1) of the work area walking frame (02), restraining the universal wheel chassis (1-1) from deviating too much to the right, causing the mobile hoist to fall to the right; the right sliding anti-fall plate (1-5-1) fits on the outer side of the right guide rail square tube (2-1-1) of the work area walking frame (02), restraining the universal wheel chassis (1-1) from deviating too much to the left; the sliding anti-fall plates (1-5-1) on the left and right sides cooperate with each other to ensure that the mobile hoist (01) can only move forward and backward on the work area walking frame (02) and will not deviate to the left or right.

[0066] The sliding anti-falling plate (1-5-1) comprises: a main body plate (1-5-1-1), a flange-type bull's eye wheel (1-5-1-2), a thrust bearing (1-5-1-3), a spacing ring (1-5-1-4), a self-lubricating shaft sleeve (1-5-1-5), and a bull's eye wheel with a rod (1-5-1-6); the flange-type bull's eye wheel (1-5-1-2) is installed in a stepped through hole in the middle and lower part of the main body plate (1-5-1-1), and its spherical surface contacts the outer side surface of the guide rail square tube (2-1-1) to reduce the resistance of the sliding anti-falling plate (1-5-1); the embodiment adopts "universal ball CY-25B stainless steel heavy-duty bull's eye wheel (special for assembly line)", the bull's eye wheel is thickened, has good wear resistance, extremely low rolling resistance, and has a tight and firm structure and good sealing performance. The thrust bearing (1-5-1-3) is installed in the upper shaft seat hole of the main plate (1-5-1-1), and its main function is to bear the lateral load generated when the mobile hoist (01) deviates left and right on the working area walking frame (02) (or moves longitudinally on the interval transfer frame), and to enable the sliding anti-fall plate (1-5-1) to still swing when bearing the lateral load; the main function of the spacing ring (1-5-1-4) is to keep a certain distance between the sliding anti-fall plate (1-5-1) and the outer side of the guide rail square tube (2-1-1) during installation, so that when the mobile hoist (01) deviates left and right, the flange-type bull's eye wheel (1-5-1-2) does not contact the outer side of the guide rail square tube (2-1-1).

[0067] The anti-fall plate mounting beam (1-1-5) is convex in shape, and two shaft holes are opened on the upper part of the convex shape. The sliding anti-fall plate (1-5-1) is connected to the anti-fall plate mounting beam (1-1-5) by bolts. The self-lubricating shaft sleeve (1-5-1-5) is sleeved on the bolt rod and installed in the shaft hole of the anti-fall plate mounting beam (1-1-5). The self-lubricating shaft sleeve (1-5-1-5) of the embodiment adopts an oil-free copper bushing, which is suitable for compact space, wear-resistant and corrosion-resistant (can be used in humid, corrosive gas or liquid environment), and is easy to install and replace.

[0068] The bull's eye wheel with rod (1-5-1-6) is installed at the bottom corner end of the main plate (1-5-1-1) (the corner is close to the direction of the interval transfer frame (03)), and its function is to reduce the friction resistance between the bottom corner end of the sliding anti-fall plate (1-5-1) and the anti-fall plate longitudinal support bar (3-1-7) or the anti-fall plate transverse support bar (3-1-9) when the mobile hoist (01) moves longitudinally or transversely on the interval transfer frame (03).

[0069] like Fig. 9 , Fig.10As shown: at the connection between the guide rail square tube (2-1-1) of the work area walking frame (02) and the transverse guide rail (3-1-1) of the interval transfer frame (03), an anti-fall plate guide block (3-1-4) is installed, the upper part of the anti-fall plate guide block (3-1-4) is an inclined surface, and a roller is installed at the upper end (its function is to reduce friction); the upper end of the anti-fall plate guide block is connected to the anti-fall plate transverse support bar (3-1-9); the anti-fall plate transverse support bar (3-1-9) is fixed on the outer side of the transverse guide rail (3-1-1); when the mobile hoist (01) moves laterally from the work area walking frame (02) to the interval transfer frame (03) (this state is referred to as the corner state), the sliding anti-fall plate (1-5 -1) Under the action of the anti-fall plate guide block (3-1-3), it is tilted and separated from the guide rail square tube (2-1-1), and dragged and slid laterally on the anti-fall plate horizontal support bar (3-1-9); in the corner state, the sliding anti-fall plate (1-5-1) does not have the "walking guidance; anti-falling" safety protection function; the "guiding and anti-falling" safety protection is achieved by the cooperation of the corner guide wheel (1-5-3) and the corner protection frame (3-1-4) and the horizontal side protection frame (3-1-8); in addition: if the rear sliding anti-fall plate (1-5-1) is still on the work area walking frame (02) and remains in a drooping state, the sliding anti-fall plate (1-5-1) still has a certain "guiding and anti-falling" safety protection function.

[0070] The corner guide wheel (1-5-3) is installed at the upper middle position of the gantry column (1-2-1) of the mobile hoist (01); long guard bars are fixed on the top of the corner protection frame (3-1-4), the longitudinal side protection frame (3-1-5), and the transverse side protection frame (3-1-8), and the height of the long guard bar matches the height of the corner guide wheel (1-5-3) of the mobile hoist (01); the corner guide wheel (1-5-3) of the embodiment adopts the finished product of "plastic-coated bearing + stainless steel shaft with screw", and is covered with nylon wheels, and has buffer and wear-resistant properties.

[0071] When the mobile hoist (01) is moving longitudinally on the interval transfer frame (03) (this state is referred to as the interval state), the sliding anti-fall plate (1-5-1) is dragged and slid on the anti-fall plate longitudinal support bar (3-1-7) in an inclined state; in the interval state, the mobile hoist (01) is implemented with safety protection such as "guiding, anti-tipping, and anti-falling" by components such as corner guide wheels (1-5-3), corner protection frames (3-1-4), longitudinal side protection frames (3-1-5), and longitudinal guide rail protection plates (3-1-6).

[0072] The present invention also provides a method for using a mobile hoisting device used in a pretreatment process before sowing rice seeds, wherein the typical mobile hoisting device with three water tanks is used to perform intermittent seed soaking / disinfection treatment on the rice seeds, and the method comprises the following steps.

[0073] s1. Prepare seed frames: place the required number of seed frames (05) in the lifting area of ​​the walking frame (02) in the left work area; the seed frames (05) of this embodiment are surrounded by fine mesh materials on all sides and at the bottom, which is conducive to water permeability and ventilation; the seed frames (05) have handles at both ends to facilitate manual handling, and the seed frames have hanging rings or hanging rope loops for quickly hanging hooks; ordinary mesh plastic baskets (tied with hanging rope loops) can also be used; seeds are added to the seed frames (05) in turn; to prevent the seeds in the seed frames (05) from overflowing due to water disturbance, a mesh plate is placed on the top of the seeds in each seed frame (05); or the seeds are put into a woven bag and then put into the frame; to facilitate manual handling and reduce labor intensity, it is appropriate to place no more than 50 kilograms of seeds in each seed frame (05).

[0074] s2. Stacked frame seed soaking: Push the mobile hoisting machine (01) to the hoisting area of ​​the left work area traveling frame (02), lift, push and place the seed holding frame (05) into the seed treatment container (04) under the current work area traveling frame (02) in turn, and stack the seed holding frame (05) in two layers; the schematic water tank of the embodiment is 2.0M long*1.2M wide*0.9M high; theoretically, it can soak more than 1000KG of rice seeds (about 12,000 trays can be grown, and 300-350 mu of field can be planted by machine); inject clean water into the left seed treatment container (04), and soak the rice seeds in the seed holding frame (05) for 8-10 hours.

[0075] S3. Lifting and transporting exposed seeds: Use a mobile hoisting machine (01) to lift the seed frames (05) in the seed treatment container (04) under the left-side working area walking frame (02) in turn, push them to the lifting area of ​​the left-side working area walking frame (02), and then lower them. Place them in layers and overlap on the ground in the lifting area and leave them to air for 6 to 8 hours; perform the "exposed seed" treatment.

[0076] S4, transfer medicine pool: pre-inject an appropriate amount of clean water into the middle seed treatment container (04), and put in disinfectants (such as 25% prochloraz 2000-3000 times solution, or 500 times strong chlorpyrifos, etc.); use a mobile hoist (01) to sequentially lift the seed frames (05) stacked in the lifting area of ​​the left work area walking frame (02), and transfer them to the seed treatment container (04) of the middle work area walking frame (02) via the left transfer frame (3-1), the interval walking frame (3-2), and the middle transfer frame (3-3); stack the seed frames (05) in layers, and soak the seeds in the medicine for 8-10 hours.

[0077] S5. Lifting and cleaning: Use a mobile hoist (01) to lift the seed frame (05) in the middle seed treatment container (04), push it to the lifting area of ​​the walking frame (02) in the middle side work area, land it on the ground and lay it flat; use a water pipe to rinse the seeds in the seed frame (05) to avoid residual pesticides; then let it air-dry for 4 to 6 hours to carry out "exposed seed" treatment; a cleaning pool can also be set up under the lifting area. Before placing the seed frame (05) on the ground, the mobile hoist (01) can be used to repeatedly lift the seed frame (05) in the cleaning pool and immerse it several times to achieve a rinsing effect. It is faster and easier than flushing with a water pipe, and the cleaning effect is better.

[0078] S6. Transfer and soak seeds: Pre-inject an appropriate amount of clean water into the right seed treatment container (04); use a mobile hoist (01) to sequentially lift the seed holding frame (05) in the lifting area of ​​the middle work area walking frame (02), and transfer and place the seeds in the right seed treatment container (04) via the middle transfer frame (3-1), the right transfer frame (3-3), and the right work area walking frame (02); and soak the seeds for 6 to 8 hours after stacking them in layers.

[0079] S7, intermittent seed soaking: Use a mobile hoist (01) to lift the seed frames (05) in the right seed treatment container (04) to the lifting area of ​​the walking frame (02) in the right work area, place them in layers and overlap them, and let them air-dry for 4 to 6 hours; then transfer them from the lifting area to the right seed treatment container (04) to soak them for 6 to 8 hours; repeat several times until the seeds meet the requirements, then lift the seed frames (05) out and transport them from the lifting area to complete the seed soaking treatment of this batch of seeds; this process is affected by temperature and other environmental factors and usually takes 48 hours or longer. For example, when the temperature is 20°C, the total time for intermittent seed soaking / disinfection is generally 60 hours, and the soaking time is preferably about 44 hours.

[0080] S8, parallel operation: the seeds are subjected to "intermittent seed soaking" treatment in the right seed treatment container (04), and the mobile hoist (01) can simultaneously perform related operations such as second batch seed soaking and disinfection in the left seed treatment container (04) and the middle seed treatment container (04), so as to give full play to the efficiency of equipment and personnel.

[0081] The method for intermittent seed soaking / disinfection using the mobile lifting equipment provided by the present invention can save a lot of manpower, reduce labor intensity, improve work efficiency and agronomic quality, and two people can easily complete the standard agronomic processing process of thousands of rice seeds, avoiding the traditional "long-term soaking, resulting in oxygen rot and germination failure of rice seeds".
