Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of agricultural machinery, and in particular to an automatic rapeseed seedling transplanter and a transplanting method thereof. Background Art
[0002] For a long time, rapeseed has been cultivated using a traditional method: manual seeding in nursery fields, hand-pulling seedlings after they mature, and then transplanting them to the field. This method, commonly known as bare-seedling transplanting, is labor-intensive and inefficient. With the increasing shortage of agricultural labor and rising labor costs, this traditional method has seriously dampened farmers' enthusiasm for rapeseed cultivation.
[0003] The application number is CN202110349684.6, which is a rapeseed seedling transplanting mechanism. The mechanism comprises a main body, a fixed frame fixedly installed inside the main body, a plurality of groups of digging devices fixedly installed inside the fixed frame, and the digging devices are arranged in rows with equal distances. The fixed frame is fixedly installed with a discharge barrel on the side close to the digging device, and the bottom ends of the discharge barrel and the digging device are both passed through the bottom side of the main body. A mounting opening is provided on one side of the top of the main body, and a conveyor belt is fixedly installed inside the mounting opening, and a plurality of groups of pusher clamps are fixedly installed on the surface of the conveyor belt. A storage bin is fixedly installed on the top side of the main body close to the mounting opening, a partition is provided inside the storage bin, and a plurality of groups of drive rollers are fixedly installed on the surface of the partition, which can effectively improve the transplanting efficiency of the rapeseed seedlings. However, after the digging device digs the pit, if the soil is soft, the broken soil will cause different degrees of backfill. The rapeseed seedlings that fall into the pit by gravity alone are prone to being planted too shallowly, which may reduce the survival rate.
[0004] Therefore, the existing technology needs to be improved. Summary of the Invention

DETAILED DESCRIPTION
[0030] Example 1
[0031] Please refer to Figures 1 to 6 , shown is an automatic rapeseed seedling transplanter provided by an embodiment of the present invention, which is used for automatically transplanting rapeseed seedlings. The specific structure is as follows.
[0032] Please refer to Figure 1 As shown, the rapeseed seedling automatic transplanter of the embodiment of the present invention is mainly composed of five parts: a body 1, a loosening mechanism 2, a pit setting mechanism 3, a planting mechanism 4 and a seedling delivery mechanism 5, wherein the body 1 is used for moving forward and provides an installation platform for other components; the loosening mechanism 2 is used for plowing the soil; the pit setting mechanism 3 is used for opening planting pits on the land; the seedling delivery mechanism 5 is used for delivering the rapeseed seedlings into the planting mechanism 4, and the planting mechanism 4 is used for delivering the rapeseed seedlings into the planting pits.
[0033] It should be noted that the planting cup used for cultivating rapeseed seedlings in this embodiment is a degradable conical planting cup 7 made of degradable paper products. It has a conical shape with a pointed bottom and a thick top, which facilitates insertion into the soil. At the same time, the top of the degradable conical planting cup 7 has an outward edge 701. In other embodiments, the interior of the degradable conical planting cup 7 can have barbs or protrusions to enhance the connection between the cultivation soil inside and the degradable conical planting cup 7, preventing the cultivation soil and the degradable conical planting cup 7 from separating when the degradable conical planting cup 7 is accelerated and falls.
[0034] Combine Figure 1 As shown, the vehicle body 1 can be a conventional tractor platform suitable for field use, which has the advantages of heavy load capacity and mature technology. The soil loosening mechanism 2 can be a conventional three-claw tilling harrow. The soil loosening mechanism 2 is mounted on the head of the vehicle body 1. When the operator drives the rapeseed seedling automatic transplanter through the field, the soil loosening mechanism 2 automatically plows the soil, making it fluffy and more suitable for crop growth.
[0035] Combine Figure 1 and Figure 6 As shown, the pit setting mechanism 3 mainly consists of three parts: an electric telescopic device 301, a telescopic rod 302, and a conical head 303. The electric telescopic device 301 can be a hydraulic telescopic cylinder in the prior art. The hydraulic telescopic cylinder is mounted on the body 1 and located behind the soil loosening mechanism 2. The hydraulic telescopic cylinder has a vertical downward telescopic rod 302, and the end of the telescopic rod 302 has a conical head 303. When the telescopic rod 302 extends downward, the conical head 303 penetrates the soil, and the telescopic rod 302 then retracts upward, leaving a conical planting pit in the soil, thus completing the planting pit operation.
[0036] It should be noted that the surface of the conical head 303 can be provided with barbs. When the conical head 303 is inserted into the ground and rises, the barbs can turn over the soil to make the planting hole larger. In addition, due to the vibration of the body 1 itself, the soil on the surface of the conical head 303 can be shaken off, making it easier to open the planting hole next time.
[0037] Please refer to Figure 1 As shown, a square box is provided in the middle position of the vehicle body 1, which is located on the rear side of the pit setting mechanism 3, and the seedling delivery mechanism 5 and the planting mechanism 4 are both installed inside the box, and the seedling delivery mechanism 5 is located on the upper side of the planting mechanism 4.
[0038] Furthermore, since the rapeseed seedling automatic transplanter of this embodiment can plant three rows at the same time, three pit setting mechanisms 3, seedling delivery mechanisms 5, and planting mechanisms 4 are all arranged side by side. Figure 1 and Figure 5As shown, each seedling delivery mechanism 5 is composed of two conveyor belts, each of which includes a conveyor belt 502 and two pulleys 501. The conveyor belt 502 is sleeved on the two pulleys 501. A transmission shaft 503 passes through all the pulleys 501 on the right side. A second motor 504 is installed on the outer wall of the box. The main shaft of the second motor 504 and the transmission shaft 503 are connected by a coupling, and the pulleys 501 are driven to rotate by the second motor 504. Each pulley 501 on the left side is fixed to the inner wall of the box by a metal strip, which does not affect the transmission of the degradable conical planting cups 7.
[0039] Furthermore, combined Figure 1 and Figure 5 As shown, in order to control the frequency of feeding the degradable conical planting cup 7 into the planting mechanism 4 in an orderly and uniform manner, a flip baffle 101 that can be flipped is hinged on the box body, and a third motor 102 is installed on the outer wall of the box body. The main shaft of the third motor 102 is connected to the flip baffle 101. The third motor 102 can drive the flip baffle 101 to flip 90° clockwise to achieve "lifting", or the third motor 102 can drive the flip baffle 101 to flip 90° counterclockwise to achieve "blocking".
[0040] During use, a worker places the degradable conical planting cups 7 in the seedling tray between the two conveyor belts 502. The two conveyor belts 502 lift the edges 701 of the degradable conical planting cups 7, transporting them from right to left. Due to the obstruction of the flip baffle 101, the edge 701 of the leftmost degradable conical planting cup 7 abuts against the flip baffle 101, preventing it from moving further left and allowing the degradable conical planting cups 7 to be arranged in an orderly manner. The flip baffle 101 then rotates 90° clockwise around the top, causing the leftmost degradable conical planting cup 7 to automatically fall into the planting mechanism 4. The flip baffle 101 then quickly rotates 90° counterclockwise, blocking the next degradable conical planting cup 7 and releasing it when the time is right. By controlling the third motor 102 and the second motor 504, the release rate of the degradable conical planting cups 7 can be controlled, thereby controlling the planting interval.
[0041] Combine Figure 1 、 Figure 2 and Figure 3 As shown, in some implementations of this embodiment, the planting mechanism 4 is mainly composed of a cylinder 401 installed on the vehicle body 1, and the cylinder 401 is installed vertically, and as shown in FIG. Figure 5 As shown, the top end of the cylinder 401 is aligned with the left end of the conveyor belt 502, so as to easily catch the fallen degradable conical planting cup 7.
[0042] Further, combined Figure 2 and Figure 3As shown, the left and right inner walls of the cylinder 401 each have a horizontal bar-shaped transverse chamber 4011, and the transverse chamber 4011 contains a spring 402 and a latch 403, with the spring 402 abutting against the end surface of the latch 403. Figure 3 As shown, the left end of the latch 403 has an upward inclined surface, which can lift the bottom of the edge 701 and play a better limiting role.
[0043] Things that need to be explained, such as Figure 3 As shown, the top of the right end of the latch 403 has an upward protrusion, which serves as a limit to prevent the latch 403 from completely separating from the horizontal cavity 4011.
[0044] Combine Figure 1 and Figure 2 As shown, the air pump 6 is mounted on the vehicle body 1. The air outlet pipe of the air pump 6 is connected to a hose 601, which is in turn connected to an L-shaped rigid tube 602. The horizontal rotation mechanism 8 mainly consists of a first motor 801 and a rotating disk 802. The first motor 801 is fixedly mounted on the vehicle body 1, with the main shaft of the first motor 801 extending vertically upward. The rotating disk 802 is fixed to the top of the main shaft of the first motor 801. The L-shaped rigid tube 602 includes a horizontal section and a vertical section. The horizontal section of the L-shaped rigid tube 602 is fixedly connected to the rotating disk 802.
[0045] Further, combined Figure 2 and Figure 4 As shown, two openings 4012 are provided on the cylinder 401. The rotating disk 802 on the left drives the L-shaped hard tube 602 to deflect counterclockwise through the opening 4012 on the left, and the rotating disk 802 on the right drives the L-shaped hard tube 602 to deflect clockwise through the opening 4012 on the right, so that the L-shaped hard tube 602 is outside the cylinder 401, which does not affect the normal falling of the degradable conical planting cup 7. The hose 601 does not affect the movement of the L-shaped hard tube 602. After the degradable conical planting cup 7 falls into the cylinder 401, the pin 403 restricts the degradable conical planting cup 7, and then the rotating disk 802 on the left drives the L-shaped hard tube 602 to deflect clockwise, and the rotating disk 802 on the right drives the L-shaped hard tube 602 to deflect counterclockwise. The end of the vertical section of the L-shaped hard tube 602 abuts the edge 701 (at this time Figure 3 As shown), the pump 6 is started to generate a high-speed airflow that is blown out through the port of the L-shaped hard tube 602. The high-speed airflow impacts the edge 701, causing the degradable conical planting cup 7 to break through the resistance of the pin 403. Since the pin 403 has an upward inclined surface, the pin 403 retracts into the horizontal chamber 4011, and the degradable conical planting cup 7 accelerates to fall and quickly penetrates into the planting pit, and can be inserted to a deeper depth. The degradable conical planting cup 7 is also more firmly inserted into the soil.
[0046] The working principle of this embodiment is as follows:
[0047] The automatic rapeseed seedling transplanter only requires the cooperation of a driver and a worker. The driver drives the rapeseed seedling automatic transplanter through the field, while the worker places the degradable conical planting cup 7 containing the rapeseed seedlings in the seedling tray onto the seedling delivery mechanism 5. The seedling delivery mechanism 5 transports the degradable conical planting cup 7 to the top of the cylinder 401. The degradable conical planting cup 7 automatically falls into the cylinder 401 and is temporarily locked by the latch 403. The soil loosening mechanism 2 plows the land, and the pit setting mechanism 3 creates a planting pit in the soil. The pump releases gas to the edge 701 of the degradable conical planting cup 7 through the L-shaped hard tube 602. The extremely fast airflow pushes the degradable conical planting cup 7 over the resistance of the latch 403, accelerating its descent from the cylinder 401 and accurately landing in the planting pit. Due to the sharp bottom of the degradable conical planting cup 7 and the speed of its descent, it can be inserted deeper into the soil, avoiding shallow planting and ensuring a high survival rate.
[0048] Example 2
[0049] This embodiment provides a method for transplanting rapeseed seedlings, which uses the above-mentioned rapeseed seedling automatic transplanter and further includes the following steps:
[0050] S1. The seedling tray with a degradable conical planting cup 7 is transported to the vicinity of the automatic transplanter by a transport vehicle, and then the worker stacks the seedling tray with a degradable conical planting cup 7 and places it on the multi-layer rack of the rapeseed seedling automatic transplanter, and then drives the rapeseed seedling automatic transplanter to the land to be transplanted;
[0051] S2. By setting the working rate of the electric telescopic device 301, the speed of the second motor 504 and the third motor 102, and the operating frequency of the first motor 801 and the air pump 6, the pit setting distance of the pit setting mechanism 3 is debugged, and then the worker places the degradable conical planting cup 7 in the seedling tray on the seedling delivery mechanism 5;
[0052] S3. The driver drives the rapeseed seedling automatic transplanter along the transplanting route on the land, and the workers continuously add the degradable conical planting cups 7 in the seedling tray to the seedling delivery mechanism 5 to achieve continuous transplanting and planting.
