Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting, and in particular to a soybean seedling transplanting device and a seedling transplanting method. Background Art

[0002] Soybean seeding and germination is an important link that affects the high-quality production of soybeans, involving multiple aspects such as soybean variety selection, sowing time, sowing method, and sowing quality. When sowing soybeans, the emergence rate is often low due to the return of a large amount of straw from the previous crop and the influence of high temperature and drought. The density of seedlings in the field is uneven, resulting in missing seedlings and broken ridges, which affects the final yield. Therefore, artificial replanting or transplanting is usually used to fill the areas where seedlings have not emerged in the field to increase yield.

[0003] At present, manual replanting or transplanting is commonly used, that is, manual second sowing or digging in the field where no seedlings have emerged, and then transplanting from the place where there are more seedlings. Although manual replanting or transplanting can complete the seedling work accurately, the time for replanting or transplanting is usually chosen on rainy days, and the window period is short. If a large number of seedlings have not emerged, it is difficult to complete the replanting or transplanting work in time with the efficiency of manual replanting or transplanting, so it is necessary to replant or transplant in multiple times; manual digging, burying, transportation, and transplanting are required, which has high labor costs. At the same time, the soybeans that are manually replanted or transplanted will also lead to inconsistent plant growth due to different planting dates, affecting the unified management and yield formation in the later stage.

[0004] Therefore, the existing method of artificial replanting or transplanting is difficult to complete transplanting in time within the appropriate period due to the low efficiency of artificial transplanting. At the same time, the inconsistent growth of plants in the later stage affects the unified management and yield formation in the later stage. Summary of the invention

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] like Figure 1 , Figure 4 As shown, the present invention provides a soybean seedling transplanting device, comprising:

[0045] A furrowing plow 1 is installed on one side of the frame and is used to follow the frame and dig furrows on the ground;

[0046] A seedling guide plate 2 is installed on one side of the frame, the seedling guide plate 2 is on the same side as the furrowing plow 1 and is located behind the furrowing plow 1;

[0047] The spiral chute 3 is installed on the frame, the lower end outlet of the spiral chute 3 is connected to the seedling guide plate 2, and the spiral chute 3 is used to spirally store the pot seedlings to be transplanted;

[0048] Among them, the seedling guide plate 2 can be rotated so that the outward end is tilted downward. After the furrowing plow 1 opens a groove, the seedling guide plate 2 is rotated so that its outer edge is tilted downward and placed in the groove, and moves in the groove in a straight line with the random frame. The pot seedlings in the spiral slide 3 slide out onto the seedling guide plate 2 in sequence, and then slide into the groove in sequence for planting at intervals.

[0049] The soybean seedling transplanting device of the present invention digs furrows in front of the frame by a furrowing plow 1. After the furrows are dug, the seedling guide plate 2 can be rotated and tilted in the furrow and move with the frame. In this process, since the seedling guide plate 2 rotates downward, the lower end of the spiral chute 3 is no longer blocked, and the seedlings stored in the spiral chute 3 can slide onto the seedling guide plate 2. The seedling guide plate 2 tilts toward the edge of the furrow, and the seedlings automatically slide into the furrow. Since the furrow is deep and the two side walls are steep, the seedlings hit the side walls of the furrow and fall stably into the furrow. The seedlings are neatly arranged in the furrow as the frame moves, thereby realizing continuous seedling transplanting.

[0050] Of course, a soil coverer (existing structure, not shown) is provided at the rear of the frame, and the soil coverer buries the soil on both sides of the trenching guide into the groove again, thereby burying the arranged pot seedlings in the soil.

[0051] The soybean seedling transplanting device of the present invention can be driven by agricultural machinery, or can be manually controlled by an independent drive, for example:

[0052] A trailer connected to agricultural machinery is set on the frame. This method is suitable for the situation where there is a large area of ​​seedling shortage in the planting field. The use of mechanical operation can significantly improve the transplanting efficiency;

[0053] The frame is provided with a hand-grip rod, a travel drive device, a storage power supply device, etc., so that the transplanting device can be manually controlled to move and transplant. This method is suitable for the situation where only a small area of ​​the planting field is lacking seedlings. The manual control operation is more flexible and convenient for walking between the ridges of the soybean seedlings.

[0054] Of course, the above two methods can be combined so that it can be connected to agricultural machinery and can also be disassembled for independent manual operation. The aforementioned methods are all existing conventional and mature solutions, which are relatively simple to implement and will not be elaborated on.

[0055] Among them, the use of the spiral chute 3 to store the seedlings in the pots can increase the storage capacity, and the seedlings in the pots can also slide downward continuously to achieve continuous transplanting of the seedlings in the pots.

[0056] During the seedling transplanting process, the seedlings need to be moved from the spiral chute 3 to the seedling guide plate 2, and the seedling guide plate 2 is rotatably connected to the spiral chute 3. During this process, the seedlings are easily stuck at the connection between the seedling guide plate 2 and the spiral chute 3. In this regard, the following preferred embodiments are provided.

[0057] like Figure 2 As shown, a rotating part 4 is provided at the connection between the seedling guide plate 2 and the spiral chute 3. The surface of the seedling guide plate 2 and the lower end surface of the spiral chute 3 are tangent to the rotating part 4. After the rotating part 4 rotates the seedling guide plate 2 to tilt downward, the seedling guide plate 2 and the spiral chute 3 smoothly transition through the rotating part 4.

[0058] Specifically, the rotating member 4 is used as a transition between the spiral chute 3 and the seedling guide plate 2, and the surface of the rotating member 4 is tangent to the surfaces of the seedling guide plate 2 and the spiral chute 3, so that the seedlings in the pot pass through more smoothly and the probability of jamming is reduced.

[0059] Based on the above embodiments, a preferred embodiment of a rotating member 4 is provided below.

[0060] like Figure 2 As shown, a rotating groove 321 is provided at the bottom of the lower end of the spiral chute 3, and the rotating member 4 includes a rotating roller 41 and a motor. The motor is installed on the frame to drive the rotating roller 41 to rotate. The rotating roller 41 is rotatably installed in the rotating groove 321, and the surface of the spiral chute 3 is tangent to the surface of the rotating roller 41.

[0061] The seedling guide plate 2 is fixed on the rotating roller 41, and the surface of the seedling guide plate 2 is tangent to the surface of the rotating roller 41;

[0062] Among them, the roller 41 has two limit points in the rotating groove 321. When the roller 41 rotates to the upper limit point, the seedling guide plate 2 tilts upward to block the lower port of the spiral chute 3, or when the roller 41 rotates to the second limit point, the seedling guide plate 2 tilts downward to open the lower port of the spiral chute 3.

[0063] Specifically, the rotation of the roller 41 is controlled by a motor, and the roller 41 is installed in the rotation groove 321 at the bottom of the spiral chute 3, and the seedling guide plate 2 is also connected to the roller 41. When the roller 41 rotates, the seedling guide plate 2 rotates synchronously, so that the seedling guide plate 2 can be lifted and lowered. Based on this, after the seedling guide plate 2 is lifted and tilted upward, the lower port of the spiral chute 3 can be blocked to prevent the pot seedlings from slipping out, and after the seedling guide plate 2 is lowered downward, the lower port of the spiral chute 3 can be opened to allow the pot seedlings to slide out smoothly.

[0064] Of course, in order to make the connection between the spiral chute 3 and the seedling guide plate 2 smoother, the following preferred embodiments are provided.

[0065] like Figure 1 , Figure 2 As shown, the spiral chute 3 includes a spiral portion 31 and a straight portion 32, the straight portion 32 is connected to the lower end of the spiral portion 31, the straight portion 32 is inclined downward, and the unit distance drop of the straight portion 32 is greater than the unit distance drop of the spiral portion 31, so that the seedlings on the straight portion 32 slide down faster than the seedlings on the spiral portion 31;

[0066] The rotation groove 321 is formed at the bottom of the lower end of the straight portion 32 .

[0067] Specifically, the spiral chute 3 is composed of a spiral portion 31 and a straight portion 32. The straight portion 32 is connected to the seedling guide plate 2 through a roller 41, so that the channel for seedlings to slide down is a straight line, with lower resistance, smoother sliding, and thus smoother emergence.

[0068] The unit distance drop of the straight portion 32 is greater than the unit distance drop of the spiral portion 31, so that after the seedlings slide from the spiral portion 31 to the straight portion, their acceleration increases, so that they can quickly slide down to the seedling guide plate 2, that is, after the seedlings enter the straight portion 32, they will quickly pull away from the seedlings in the spiral portion 31, so that the seedlings in close contact with the spiral portion 31 are quickly separated, that is, the seedling guide plate 2 can guide the seedlings into the groove at a certain distance, so that the transplanting effect is better.

[0069] Of course, when dealing with intermittent transplanting, only by using the guide plate 2 to lift and block the seedlings to interrupt the lowering of the seedlings, the seedlings will be piled up in the straight line, so that when they are lowered for transplanting again, more seedlings need to be lowered in the front section to achieve a certain spacing of transplanting in the back section, resulting in too high a transplanting density in the front section. Based on this, the following preferred embodiments are provided to solve the problem.

[0070] like Figure 2 As shown, two slots 322 are symmetrically arranged on the inner wall of the straight portion 32, and an air bag 323 is arranged in each slot 322, and the surface of the air bag 323 is flush with or lower than the inner wall of the straight portion 32 under normal pressure;

[0071] The airbag 323 is expanded and restored by an air pump, and the airbag 323 can clamp or block the seedlings in the pot after expansion.

[0072] Specifically, an airbag 323 is provided on the inner wall of the straight portion 32. The airbag 323 can control expansion and recovery. After expansion, the airbag 323 can clamp or block the seedlings in the pot. Therefore, the airbag 323 can clamp or block the seedlings in the pot at the upper end of the straight portion 32. There is at most one seedling interrupted on the straight portion 32, which has little effect on the transplanting seal, and the clamping of the airbag 323 has little effect on the seedlings in the pot and will not damage the seedlings.

[0073] Of course, the airbag 323 can only hold the seedlings in the pot for a short period of time. When it is necessary to change to another field for transplanting and need to walk more distance, the clamping reliability of the airbag 323 is insufficient and the seedlings in the pot may easily slip out due to shaking. Based on this, the following preferred embodiments are provided.

[0074] like Figure 2 As shown, a slide groove 324 is provided through the bottom of the straight portion 32, and a baffle 325 is slidably provided in the slide groove 324. After the baffle 325 moves upward to the upper limit position, the upper end of the baffle 325 is not lower than the height of the side wall of the straight portion 32. After the baffle 325 moves downward to the lower limit position, the upper end of the baffle 325 is flush with or lower than the inner bottom wall of the straight portion 32.

[0075] The movement of the baffle 325 is controlled by an electric push rod. The baffle 325 moves upward after a preset time delay after the airbag 323 is inflated. The airbag 323 automatically returns to its original position after moving to the upper limit position on the baffle 325 .

[0076] Specifically, the baffle plate 325 is used to block the seedlings in the straight portion 32, but the baffle plate 325 cannot intercept the seedlings that continue to slide out alone, so the airbag 323 is needed to clamp or block the seedlings first, and then control the electric push rod to raise the baffle plate 325 and restore the airbag 323 to block and interrupt. Therefore, the two ways of interrupting the transplanting of seedlings can be selected according to actual conditions.

[0077] Of course, during the transplanting process, the seedlings in the pots are stored by the spiral part 31. In order to increase the storage capacity of the spiral part 31, the following preferred embodiments are provided.

[0078] like Figure 1 As shown, the spiral diameter from the upper end to the lower end of the spiral portion 31 gradually decreases, and a fixing column 311 is provided at the axis of the spiral portion 31, the fixing column 311 is fixed on the frame, and a plurality of support rods 312 are installed on the fixing column 311, and the plurality of support rods 312 are spirally fixed around the surface of the fixing column 311, and the ends of the support rods 312 away from the fixing column 311 are fixed on the spiral portion 31.

[0079] Specifically, due to the limitations of the frame's own structure (the lower part needs to move between ridges), the diameter of the spiral portion 31 inside the frame is relatively small. Therefore, the spiral portion 31 is configured as a spiral with a spiral diameter that gradually decreases from the upper end to the lower end, so that the diameter of the portion exposed to the upper part of the frame and its outside is increased, thereby effectively increasing its storage capacity without affecting the smoothness of the sliding of the seedlings in the pot.

[0080] The spiral portion 31 may preferably have a portion located in the lower portion of the frame as an equidistant spiral, and a portion located in the upper portion of the frame and outside thereof as an involute spiral.

[0081] Based on the above embodiments, the furrowing plow 1 is used to dig grooves so that the seedlings in pots can be placed in the grooves. The grooves formed by the furrowing plow 1 are usually V-shaped, which is not conducive to the placement of flat-bottomed seedlings in pots and is prone to skewness, affecting the transplanting effect. Based on this, the following preferred embodiments are provided.

[0082] like Figure 3 As shown, the furrowing plow 1 includes a first plow blade 11 and a second plow blade 12. The second plow blade 12 is located behind the first plow blade 11. The front end of the first plow blade 11 is a pointed end, and the front end of the second plow blade 12 is a flat end. After the first plow blade 11 forms a V-shaped groove on the ground, the second plow blade 12 trims the V-shaped groove to form a trapezoidal groove to flatten the bottom of the groove.

[0083] Specifically, the tip of the first coulter 11 first opens a V-shaped groove on the ground, and the flat end of the second coulter 12 trims the V-shaped groove to form a trapezoidal groove, thereby making the bottom of the groove flat and reducing the probability of the seedlings being skewed after transplanting.

[0084] Of course, further Figure 3 As shown, a plurality of third coulters 13 are arranged between the first coulter 11 and the second coulter 12, the front end of the third coulter 13 is a flat end, and the width of the flat end is smaller than the front end width of the second coulter 12, and the front end widths of the plurality of third coulters 13 increase sequentially from front to back.

[0085] Since the width of the seedlings in the pot is relatively large, it is difficult to trim a trapezoidal groove from the V-shaped groove at one time, resulting in excessive travel resistance and affecting the operation of the furrowing plow 1. By arranging multiple third plows 13 between the first plow 11 and the second plow 12, the width of the flat ends of the multiple third plows 13 increases successively, thereby achieving gradual trimming of the V-shaped groove to form a trapezoidal groove.

[0086] It is worth noting that the furrowing plow 1 can move up and down on the frame, which belongs to the conventional technology of the plow working, not shown in the figure. Based on this, when furrowing is needed, the furrowing plow 1 descends and moves forward to form a groove. After the furrowing is completed, the furrowing plow 1 rises and leaves the ground.

[0087] Therefore, the length of the furrow can be controlled by controlling the furrowing plow 1 up and down, that is, long furrowing for large-area seedling replenishment can be achieved, and short furrowing for small-area seedling replenishment can also be achieved. However, based on its spiral chute 3, it can carry multiple potted seedlings, which is more preferred for large-area seedling replenishment and has higher efficiency.

[0088] Of course, there are also cases where a single seedling is missing in a very small number of areas. Based on this situation, it is necessary to control the up and down speed of the furrowing plow 1 to increase, that is, to complete the lowering and lifting of the furrowing plow 1 within a short moving distance, so as to open a deep and short groove, which is convenient for placing a single soybean seedling in a pot for transplanting.

[0089] Based on the above-mentioned soybean seedling transplanting device, a method for transplanting seedlings is provided, comprising the following steps:

[0090] Step 100, taking a certain amount of soil, exposing it to the sun or heating it to dry, and then crushing it, and fully mixing the soil particles with a certain amount of decomposed and air-dried organic fertilizer to form a pot seedling matrix;

[0091] Step 200, select a flat plot to dig a pit and isolate it with non-woven fabric, put the seedling pot matrix flat into the non-woven fabric in the pit, and use the non-woven fabric to isolate the seedling pot matrix into a block to form a nutrient pot body;

[0092] Or use non-woven fabric to make a pot bag in advance, put it into the pot seedling matrix to form a nutrient pot body, and then put the nutrient pot body into a pit dug in advance on a flat plot;

[0093] Step 300, during the sowing period, sowing soybean seeds on the seedling substrate in the nutrient pot body and curing them, and transplanting them after the seedlings emerge to form pot seedlings;

[0094] Step 400, take out the seedlings from the pit of the plot one by one and store them in the spiral chute of the transplanting device in sequence. After moving the transplanting device to the area to be transplanted, first use a furrowing plow to form a groove, then release the seedling guide plate to the moving device in the groove, and the furrowing plow forms a groove in front. The seedlings in the spiral chute slide down in sequence and slide from the seedling guide plate to the groove for neat arrangement.

[0095] The seedling transplanting method of the present invention is to preferentially process the substrate of the seedlings in pots, sterilize the soil by exposure to the sun or heating and drying, and then break and decompose it to increase soil nutrition, so as to form a substrate for cultivating crops in pots.

[0096] After the seedling pot matrix is ​​made, the nutrient pot body is obtained by digging a pit and laying non-woven fabric to isolate and shape it, or by placing a prefabricated non-woven fabric bag in a pit for orientation. Since the outer wall of the nutrient pot body is made of non-woven fabric, the seedling pot matrix is ​​not easy to lose and is easier to slide down the spiral chute, making transplanting convenient.

[0097] After the nutrient pot is made, sowing is carried out to form pot seedlings. The specific requirements are as follows: after sowing 1-2 seeds in a single nutrient pot, cover it with 2-3cm of pot seedling matrix; after sowing, water it until the pot seedling matrix is ​​fully moistened, and mix rhizobium agent into the water; after watering, lay a solar net to reduce water evaporation, and remove the solar net after the seedlings emerge. The sowing period is consistent with the normal sowing period.

[0098] Of course, careful management is required during this germination period. Take bean seedlings as an example: keep the soil moisture content at around 75%, manage the soil alternately between wet and dry after the single leaves unfold, and control the water appropriately to train the bean seedlings to resist drought and waterlogging; combine with chemical control drugs for spraying, supplement nitrogen, phosphorus, potassium, boron and other elements on the leaves, and spray growth control agents to improve the quality of bean seedlings.

[0099] When transplanting, it is necessary to irrigate with "fertilizer and rooting water" one day before transplanting, that is, mix a small amount of urea and salicylic acid in the irrigation water, and maintain the soil moisture of the nutrient pot on the day of transplanting. Taking bean seedlings as an example, the transplanting period is 10-15 days after emergence. Choose continuous rainy days for seedling replacement or transplanting, and add water in time after transplanting or seedling replacement.

[0100] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
