Description

Technical Field

[0001] The present invention relates to the technical field of crop planting, and in particular to an integrated automatic crop planting and fertilization device. Background Art

[0002] In modern agricultural production, the emergence of integrated automated crop planting and fertilization equipment has greatly improved the efficiency and accuracy of agricultural production. Traditional crop planting methods mostly rely on manual operation or semi-automated mechanical equipment, which not only consumes a lot of human resources, but also makes it difficult to ensure the consistency and accuracy of the fertilization and planting process. With the advancement of science and technology, various automated devices have been introduced into agricultural production to improve work efficiency, reduce labor input and optimize resource utilization.

[0003] However, when using existing crop planting equipment, the usual practice is to pour fertilizer directly on the soil surface, and then mix the fertilizer and soil evenly through mechanical stirring. This fertilization method seems to ensure that the fertilizer is in full contact with the soil. However, since the fertilizer is directly exposed to the soil surface, it is easily affected by natural factors such as rain erosion, direct sunlight and wind erosion, resulting in fertility loss, thereby reducing the effective utilization rate of the fertilizer. In addition, crop seedlings are usually planted at a certain interval, which means that the fertilizer in the soil area between two crop seedlings may not be effectively absorbed, because the root system is mainly concentrated around the plant, and the fertilizer far away from the plant may not be used for a long time, resulting in a waste of fertilizer resources. In addition, after the existing crop planting equipment transports the crop seedlings to the pre-dug pits, it is necessary to cover the soil to fix the crop seedlings, but it is easy to move soil particles to the leaves of the crop seedlings. This situation not only affects the photosynthesis of the crop, but may also cause the leaves to rot due to the humid environment, thereby affecting the healthy growth and final yield of the crop. Summary of the invention

[0004] In view of this, the present invention provides an integrated automated crop planting and fertilization device, which can overcome the shortcomings of existing crop planting equipment in which soil particles may be moved onto the leaves of crop seedlings during use, causing the leaves of the crop seedlings to rot easily and having a low fertilizer utilization rate.

[0036] In the initial state, the loading tank 3 is pre-loaded with fertilizer, and the fertilizer will gradually fall into the rotating cylinder 8 due to gravity. At the same time, the water tank 43 is also pre-loaded with a certain amount of water to prepare for subsequent irrigation. First, the mobile vehicle 1 is controlled to move to the specified position, and then multiple seedling trays 24 are placed on the placement rack 22 (such as Figure 7As shown in the figure), the protrusion on the sliding frame 2402 of the lowermost seedling tray 24 is located in the groove 2601 of the sliding fixture 26, and then the first lifting plate 5 is driven to move downward by the first electric push rod 6, and the first lifting plate 5 can drive the hollow rotating platform 7 and the rotating cylinder 8 to move downward, and the rotating cylinder 8 can drive the drill bit 9 and the hollow shifting rod 10 to move downward.

The rotating rod 14 can drive the spiral rod 12 to rotate by itself through the bevel gear assembly 15. The rotation of the spiral rod 12 can transport the fertilizer in the rotating cylinder 8 downward to the hollow shifting rod 10, and then the drill bit 9 and the hollow shifting rod 10 will be inserted into the rotating cylinder 8. The drill bit 9 can be inserted into the soil, and the horizontal rotation of the drill bit 9 can dig a hole in the soil. At the same time, the fertilizer in the hollow lever 10 will fall into the soil through the notch 1001. At the same time, the horizontal rotation of the hollow lever 10 can evenly transport the fertilizer to the surroundings of the hole, and the hollow lever 10 can evenly mix the soil and fertilizer around the hole. Then, the first lifting plate 5 can be driven by the first electric push rod 6 to move upward and reset. The first lifting plate 5 can drive the hollow rotating platform 7 and the rotating cylinder 8 to move upward and reset. The rotating cylinder 8 can drive the drill bit 9 and the hollow lever 10 to move upward and reset to separate from the soil, and the hollow rotating platform 7 and the driving motor 13 can be controlled to stop working. Then the moving trolley 1 is controlled to move a specified distance to the right, so that the rotating claw 31 moves to the top of the hole. Repeat the above operation to dig a second hole in the soil. During the process of digging the second hole in the soil, the fourth electric push rod 25 can be used to drive the sliding clamp 26 to move a specified distance to the right. The sliding clamp 26 will pull the lowermost sliding frame 2402 to move to the right, and the sliding frame 2402 will drive the seedling frame 2403 to move to the right to the left side of the top of the fixed frame 16, so that the bottom frame 2401 no longer blocks the bottom of the seedling frame 2403, and the top of the fixed frame 16 will block the bottom of the seedling frame 2403, and then the crop seedlings in the rightmost row inside the seedling frame 2403 will move to the top of the straight hole 1601. At this time, the seedling frame 2403 stops moving to the right, and the crop seedlings in the rightmost row inside the seedling frame 2403 will fall down due to gravity. To the top of the conveyor 18, the lifting frame 17 and the conveyor 18 can be driven downward by the second electric push rod 19, and the conveyor 18 can drive the crop seedlings thereon to move downward and separate from the seedling raising frame 2403, and then the crop seedlings thereon can be intermittently conveyed to the side close to each other by the conveyors 18 on the front and rear sides, so that each crop seedling can intermittently fall into the feeding pipe 20, and fall down along the feeding pipe 20 and the connecting pipe 30 to the rotating claw 31, and then the second lifting plate 27 is driven downward by the first linear drive 28 to move a specified distance, which can drive the connecting tube 29, the connecting tube 30 and the rotating claw 31 to move downward a specified distance, and the connecting tube 29 can drive the rotating shovel plate 36 to move downward a specified distance, so that the lower end of the rotating shovel plate 36 is inserted into the soil,The rotating claw 31 can drive the crop seedlings thereon to move downward a specified distance to just above the pit, and then drive the sleeve 33 to move upward a specified distance through the second linear drive 32. The sleeve 33 can drive the guide rail 34 to move upward a specified distance. The guide rail 34 can push the short rod 35 to move in the direction close to the axis of the sleeve 33, thereby driving the upper end of the rotating claw 31 to move in the direction close to the axis of the sleeve 33, causing the rotating claw 31 to rotate. At this time, the lower end of the rotating claw 31 will move in the direction away from the axis of the sleeve 33, causing the lower end of the rotating claw 31 to open slightly, and the elastic rope 3101 will stretch. At this time, the crop seedlings on the rotating claw 31 will fall down into the pit, and the soil block of the crop seedlings is located in the pit, while the stem and leaf parts of the crop seedlings are located on the rotating claw 31. The rope 3101 can block the stems and leaves of the crop seedlings to prevent the stems and leaves of the crop seedlings from protruding from the gap between the two adjacent rotating claws 31, and then the lifting sleeve 39 can be driven downward by the third linear drive 38. The lifting sleeve 39 will squeeze the roller 37 to move away from the axis of the connecting tube 29, and the roller 37 will drive the upper end of the rotating shovel plate 36 to move away from the axis of the connecting tube 29, so that the rotating shovel plate 36 rotates, and the reset spring 3601 is stretched.
