Description

Technical Field

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

[0002] During the planting and seedling raising process of crops, the sowing depth varies according to the size of the seeds. Generally, the sowing depth of small seeds (such as cabbage seeds) is 0.5-1 cm, and the sowing depth of large seeds (such as corn seeds) is 2-3 cm. If the seeds are sown too deep, they may not germinate normally due to lack of oxygen; if the seeds are sown too shallowly, they are easy to lose water and dry, affecting germination.

[0003] If you dig holes directly on the nursery bed with a shovel or awl, the depth of the holes will fluctuate greatly, and the spacing between the holes will be difficult to keep consistent. In addition, after sowing the seeds in the holes, if the soil is loose and difficult to retain moisture, it will affect the normal germination and growth of the seeds; if you compact the soil in the nursery bed, the seeds will have poor air permeability during germination and growth, and even root rot. Summary of the invention

[0015] S1. Screw and install a suitable number of counterweight rings in the pressure cylinder, snap-fit ​​the mounting plate of the mounting frame to the upper opening of the pressure cylinder, and tighten the connection between the mounting frame and the pressure cylinder.

[0016] S2. Insert one side of the guide square rod into the guide square slot of one of the horizontal screw rods, and screw the hand-held tube onto the first horizontal screw rod.

[0017] S3. Insert the other side of the guide square rod into the guide square slot of another horizontal screw rod, and screw the hand-held tube onto the second horizontal screw rod.

[0018] S4. Turn the hand-held cylinder to adjust and shorten the distance between the two pressure cylinders until it meets the requirements for the spacing of the sowing slots.

[0019] S5. Adjust the fastening nut on the horizontal screw to lock the connection between the horizontal screw and the hand-held cylinder.

[0020] S6. Connect the sowing slotted cone screw to the bottom of the pressure cylinder.

[0021] S7. Installation test: Insert two seeding slotted cones directly into the edge of the seedling bed. If the seeding slotted cones are not fully inserted into the soil of the seedling bed without manual force, add a counterweight ring in each pressure cylinder until the seeding slotted cones can be fully inserted into the soil of the seedling bed.

[0022] In addition, the present invention also provides a method for using the crop planting and seedling raising equipment, comprising the following contents:

[0023] S1. Perform the first operation along the edge of the seedling bed, insert two sowing slotted cones directly into the seedling bed, and then pull out the equipment. During the operation, the pressure cylinder where the laser pen is located is placed at the rear side.

[0024] S2. Place the sowing groove cone at the rear side into the sowing groove opened by the sowing groove cone at the front side, turn on the laser pen and adjust the angle position of the laser pen until the laser beam of the laser pen falls into the sowing groove at the rear side.

[0025] S3. Pull out the two sowing slotting cones and continue to move forward for a distance until the laser beam of the laser pen shines on the vicinity of the sowing slot most recently opened by the sowing slotting cone on the front side, move the two sowing slotting cones downward and adjust the position of the laser beam of the laser pen at the same time, so that when the two sowing slotting cones are inserted into the soil of the seedling bed, the laser beam of the laser pen shines on the range of the sowing slot most recently opened by the sowing slotting cone on the front side.

[0026] S4. Repeat the operation content of S3 until the sowing slot in the current direction is opened.

[0027] S5. When turning operation is required, repeat the operations of S1 to S4.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention installs a sowing slotted cone at the bottom of the pressure cylinder, and sets a central column in the pressure cylinder to which multiple counterweight rings can be screwed, and uses the weight of the counterweight ring to accurately control the depth of the sowing slotted cone inserted into the soil. During the installation process, if the test finds that the sowing slotted cone cannot be fully inserted into the soil of the nursery bed, the counterweight ring can be added until the appropriate depth is reached, effectively avoiding the problem of seed germination being affected by improper sowing depth.

[0030] 2. The present invention is provided with two pressure cylinders, which are screwed to the hand-held cylinder through the horizontal screw on the mounting frame, and the thread directions of the horizontal screws of the two mounting frames are opposite. The distance between the two pressure cylinders can be conveniently adjusted by rotating the hand-held cylinder. During the adjustment process, the guide square rod is inserted into the guide square slots of the two horizontal screws to ensure that the two pressure cylinders are in the same vertical position, so that the spacing between the sowing slots can accurately meet the operation requirements, thereby stabilizing the sowing spacing.

[0031] 3. The present invention arranges a suitable counterweight ring in the pressure cylinder. On the one hand, when the sowing groove cone is inserted into the soil to make a sowing groove, the counterweight ring has a certain compaction effect on the soil around the sowing groove. Compared with directly compacting the entire soil of the nursery bed, this local moderate compaction method is beneficial to maintaining the moisture of the soil in the sowing groove and providing a suitable humidity environment for seed germination; on the other hand, it will not cause problems such as poor air permeability and root rot during the seed germination and growth process like completely compacting the soil, thereby effectively optimizing the soil conditions for seed germination and growth.

[0050] Embodiment 2: The steps of installing the device of the present invention are as follows:

[0051] First, install the weight ring and the mounting frame: according to the texture of the soil in the nursery bed and the seed sowing depth requirements, select a suitable number of weight rings 2 in the pressure cylinder 1, and screw them together through the inner ring screw hole 201 and the outer thread 102 of the center column 101. Then, accurately fit the mounting plate 301 of the mounting frame 3 on the upper opening of the pressure cylinder 1, and use tools to tighten the connection between the mounting frame 3 and the pressure cylinder 1, for example, bolts can be used to ensure a firm connection.

[0052] Second, install the guide square rod and the hand-held tube: slowly insert one side end of the guide square rod 7 into the guide square slot 3031 of one of the horizontal screw rods 303. Then, screw the hand-held tube 6 onto the first horizontal screw rod 303 through the horizontal thread 601 on the inner wall, and pay attention to the degree of tightening to avoid being too loose or too tight to affect subsequent operations. After that, insert the other side end of the guide square rod 7 into the guide square slot 3031 of another horizontal screw rod 303, and screw the second hand-held tube 6 onto the horizontal screw rod 303.

[0053] Third, adjust and fix the spacing: Hold and rotate the hand-held cylinder 6 to gradually shorten the spacing between the two pressure cylinders 1. During the adjustment process, observe the spacing changes until it meets the preset spacing requirements for opening the sowing slot. After the adjustment is completed, use a tool to adjust the fastening nut 305 on the horizontal screw 303 to firmly lock the connection between the horizontal screw 303 and the hand-held cylinder 6 to prevent the spacing from changing during the operation.

[0054] Fourth, install the sowing slotted cone: align the top screw 401 of the sowing slotted cone 4 with the lower position of the vertical screw hole 103 of the center column 101, and rotate the sowing slotted cone 4 to make the top screw 401 tightly screwed with the vertical screw hole 103 to ensure that the sowing slotted cone 4 is firmly installed.

[0055] Finally, the installation test: insert the two seeding slotted cones 4 of the installed equipment directly into the edge of the seedling bed 9 and observe without the help of additional force. If the seeding slotted cone 4 is not fully inserted into the soil of the seedling bed 9, it indicates that the weight of the equipment is insufficient, and a counterweight ring 2 needs to be added to each pressure cylinder 1. After adding the counterweight ring, perform the insertion test again, and repeat the operation until the seeding slotted cone 4 can be fully inserted into the soil of the seedling bed 9, and the equipment installation is completed.

[0056] Embodiment 3: The operation and use method of the device of the present invention is as follows:

[0057] First, the first operation is performed: the starting position is selected at the edge of the seedling bed 9, and the pressure cylinder 1 where the laser pen 8 is located is placed at the rear side of the device. Holding the hand-held cylinder 6, two sowing slotting cones 4 are vertically inserted into the seedling bed 9 to a suitable depth, and then the device is smoothly pulled out, and the initial sowing slot 901 is opened on the seedling bed 9.

[0058] Second, calibrate the laser pointer: Combine Figure 8 , put the sowing slot cone 4 at the rear side into the sowing slot 901 opened by the sowing slot cone 4 at the front side, and turn on the laser pen 8. By adjusting the tightening disk 105, the angle position of the laser pen 8 is adjusted so that the laser beam emitted by the laser pen 8 accurately falls into the sowing slot 901 at the rear side, and the calibration of the laser pen 8 is completed, providing an accurate positioning reference for subsequent operations.

[0059] Third, continue the operation: pull out the two sowing slotting cones 4 from the current position, and move the handheld device forward along the seedling bed 9 for a distance. During the movement, observe the laser beam of the laser pen 8. When the laser beam irradiates the vicinity of the sowing slot 901 most recently opened by the front sowing slotting cone 4, slowly move the two sowing slotting cones 4 downward. At the same time, fine-tune the angle of the laser pen 8 according to the position of the laser beam to ensure that when the two sowing slotting cones 4 are inserted into the soil of the seedling bed 9, the laser beam of the laser pen 8 is just irradiated within the range of the sowing slot 901 most recently opened by the front sowing slotting cone 4. Repeat this step until all sowing slots in the current direction are opened.

[0060] Fourth, U-turn operation: when the operation direction needs to be changed, return to the starting position at the edge of the seedling bed 9, and operate again according to the steps of the first operation, calibrating the laser pen, and continuous operation to complete the sowing slot opening operation after the U-turn, until the sowing slot opening task of the entire seedling bed 9 is completed.
