Description

Technical Field

[0001] The invention relates to the technical field of fertilizing devices, and in particular to an automatic fertilizing device for maintaining horticultural plants. Background Art

[0002] In the process of artificial cultivation, plants need to be fertilized to meet the needs of plant growth. In the process of horticultural plant maintenance, a fertilization device is needed to meet the nutrient needs of horticultural plants and improve fertilization efficiency. The fertilization device can realize automatic fertilization and reduce manual input and labor intensity.

[0003] During use, the fertilization device applies fertilizer to the planting site. When applying fertilizer, the existing fertilization device guides the fertilizer in the fertilizer storage container to the land through a pipeline. During the fertilizer application process, the fertilizer is controlled by the diameter of the pipeline, and its amount is not easy to control, so that the fertilizer application is uneven and difficult to adjust. For example, Chinese patent announcement number CN221429551U in the prior art discloses a fertilization device, which includes a base, and universal wheels are fixedly installed at the four corners of the bottom surface of the base, and a cylinder is provided on the top surface of the base. The bottom surface of the cylinder is fixedly installed on the top surface of the base through supporting legs. A feed inlet is opened on one side of the top surface of the cylinder. A friction ring is fixedly installed on the inner wall of the cylinder. The inner wall of the friction ring is an hourglass-shaped structure. A truncated cone-shaped friction block is provided in the friction ring. The outer circumference inclination angle of the friction block is less than the inclination angle of the lower part of the inner wall of the friction ring. A moving device for driving the friction block to move up and down is provided in the cylinder, and a rotating device for driving the friction block to rotate is provided in the cylinder. A stirring device is provided at the bottom of the cylinder, and a material sprinkling device is provided at the bottom of one side of the cylinder. In the disclosed device, fertilizer is sprinkled through a sprinkler pipe in the sprinkler during fertilization, and the amount of fertilizer applied is difficult to control, especially when the walking speed of the device is inconsistent. The amount of fertilizer sprinkled in the same time is consistent, more fertilizer is applied to places where the walking speed is slow, and less fertilizer is applied to places where the walking speed is fast, resulting in uneven fertilizer application.

A receiving port 312 opposite to the discharge port is provided at the upper end of the box 31, and a dropping port 313 connected to the circular cavity 311 is provided at the bottom of the fixed box 31. During the rotation of the distributing plate 32, the distributing trough 321 rotates from the receiving port 312 to the dropping port 313 to pack and transfer the fertilizer dropped from the receiving port 312 to the dropping port 313 for discharge; a rotating shaft 4 is rotatably connected to the frame 1, and rollers 41 are fixedly connected at both ends of the rotating shaft 4. The rotating shaft 4 is transmission-connected to the distributing plate 32 to drive the distributing plate 32 to rotate during the walking and rolling of the roller 41.

[0032] By adopting the above technical solution, during the fertilization process, the fertilizer is placed in the storage hopper 2, and the roller 41 is driven to rotate by the rotation of the rotating shaft 4, thereby driving the fertilization device to move. At the same time, the rotation of the rotating shaft 4 drives the distribution plate 32 to rotate, and when the distribution trough 321 passes the discharge port, the fertilizer in the storage hopper 2 falls into the distribution trough 321, and the distribution plate 32 rotates to drive the distribution trough 321 to rotate and put the fertilizer in the distribution trough 321 into the drop port 313, and the fertilizer falls to the ground along the drop port 313; The trough 321 quantitatively distributes the fertilizer and applies the fertilizer, so that the fertilizer application is more uniform; during the movement of the fertilizing device, automatic fertilization is simultaneously realized to maintain the consistency of movement and fertilization; when the movement speed of the fertilizing device is accelerated, the roller 41 rotates faster, thereby driving the distribution plate 32 to rotate faster, so that the distribution trough 321 can distribute the fertilizer in the storage hopper 2 to the ground more, thereby performing adaptive fertilizer application according to the movement speed of the fertilizing device, thereby maintaining a consistent amount of fertilizer within the same fertilization distance.

One end of the first compression spring 35 abuts against the upper end of the connecting cavity 323, and the other end of the first compression spring 35 abuts against the step block 331. The ejecting rod 33 is limited in the connecting cavity 323 by the step block 331, and the elastic force provided by the first compression spring 35 makes the upper end of the ejecting rod 33 retract into the connecting cavity 323 when the ejecting rod 33 is not lifted by the cam 34.

[0035] Specifically, one end of the end of the ejector rod 33 extending into the second circular mounting cavity 322 is in an arc shape, so that the cam 34 can contact the end of the ejector rod 33 to push the ejector rod 33 upward.

[0036] The frame 1 is provided with a driving motor 5, the output shaft of which is fixedly connected with a first sprocket 51, the rotating shaft 4 is fixedly connected with a second sprocket 42, and a chain is arranged between the first sprocket 51 and the second sprocket 42 to form a chain drive; the center position of one side of the distribution plate 32 is fixedly connected with a first transmission shaft 36, the first transmission shaft 36 is fixedly connected with a third sprocket 361, the output shaft of the driving motor 5 is fixedly connected with a fourth sprocket 52, and a chain is arranged between the third sprocket 361 and the fourth sprocket 52 to form a chain drive. The driving motor 5 adopts a chain drive to drive the rotating shaft 4 to rotate and then drive the roller 41 to rotate and drive the fertilizer device to move. At the same time, the output shaft of the driving motor 5 drives the first transmission shaft 36 to rotate through the chain drive, thereby causing the fertilizer device to move and drive the distribution plate 32 to rotate. The distribution plate 32 rotates so that the distribution trough 321 quantitatively packs the fertilizer and then transports it to the drop port 313 below to spill it.

[0037] The material distribution trough 321 is provided with a movable block 37 that slides along the material distribution trough 321, and a connecting rod 38 is hingedly connected to the side of the movable block 37 close to the second circular installation cavity 322.

The movable block 37 divides the material distribution trough 321 into a material receiving cavity. The size of the material receiving cavity is adjusted by adjusting the position of the movable block 37, and then the amount of fertilizer is adjusted.

[0038] Specifically, the end of the adjusting screw 39 away from the material distribution trough 321 is fixedly connected with a hand wheel for rotating the adjusting screw 39. The hand wheel is provided to facilitate the rotation of the adjusting screw 39, thereby facilitating the adjustment of the fertilizer amount.

[0039] A furrowing plow 11 is fixedly connected to the bottom of the frame 1, and the furrowing plow 11 is located in front of the moving direction of the drop port 313.

A scraper 14 is arranged at the lower end of the vertical shaft 12, and the scrapers 14 on the two vertical shafts 12 are staggered. One of the vertical shafts 12 is transmission-connected to the distribution plate 32 so that the distribution plate 32 rotates and drives the vertical shaft 12 to rotate at the same time; the rotation of the vertical shaft 12 drives the scraper 14 to rotate and backfill the soil on the ground into the fertilizer trench opened by the furrowing plow 11. The fertilizer device moves to drive the furrowing plow 11 to open a fertilizer furrow on the land, and the fertilizer spilled from the drop port 313 falls into the fertilizer furrow. The vertical shaft 12 drives the scraper 14 to rotate, and then the soil from the plowed land to both sides of the fertilizer furrow is backfilled into the fertilizer furrow to cover the fertilizer, so as to prevent the fertilizer from being washed away by rainwater; while the fertilizer device moves to apply fertilizer, it opens a furrow and backfills the place after fertilization, thereby improving the overall work efficiency. The scrapers 14 are staggered so that the scrapers 14 on the two vertical shafts 12 do not interfere with each other during rotation.

[0040] A telescopic hole is provided at the lower end of the vertical shaft 12, a telescopic rod 15 is slidably connected in the telescopic hole, a second compression spring 16 is provided in the telescopic hole, the second compression spring 16 abuts against the upper end of the telescopic rod 15, and the scraper 14 is fixedly connected to the lower end of the telescopic rod 15. By providing the telescopic rod 15 with a telescopic function on the vertical shaft 12, when the scraper 14 encounters a raised terrain on the ground during the process of rotating and scraping the soil, the telescopic rod 15 contracts to avoid the raised terrain, thereby avoiding hard contact and damaging the scraper 14.

[0041] The first transmission shaft 36 is fixedly connected with a fifth sprocket 362, the frame 1 is rotatably connected with a second transmission shaft 6, the second transmission shaft 6 is fixedly connected with a sixth sprocket 61, and a chain is arranged between the fifth sprocket 362 and the sixth sprocket 61 to form a chain drive; the upper end of one of the vertical shafts 12 is fixedly connected with a first bevel gear 17, the second transmission shaft 6 is fixedly connected with a second bevel gear 62, and the first bevel gear 17 and the second bevel gear 62 are meshed with gears to form a gear drive. Through the coordination of chain drive and gear drive, the second transmission shaft 6 is driven to rotate during the rotation of the material distribution plate 32, and then the vertical shaft 12 is driven to rotate to drive the scraper 14 to rotate, and the scraper 14 rotates to move the soil on both sides of the fertilizer ditch into the fertilizer ditch.

[0042] The bottom of the drop opening 313 is fixedly connected with a fertilizer pipe 7. The fertilizer spilled from the drop opening 313 is introduced into the fertilizer ditch below through the fertilizer pipe 7 to prevent the fertilizer from scattering.

[0043] The working principle of the automatic fertilizing device for horticultural plant maintenance provided by the present invention is as follows: during the fertilization process, the fertilizer is placed in the storage hopper 2, and the driving motor 5 drives the roller 41 to rotate to drive the fertilizing device to move, while driving the furrowing plow 11 to move to dig a fertilizer ditch on the ground; at the same time, the rotation of the rotating shaft 4 drives the distribution plate 32 to rotate, and the distribution plate 32 rotates so that the fertilizer in the storage hopper 2 falls into the distribution trough 321 when the distribution trough 321 passes through the discharge port, and the rotation of the distribution plate 32 drives the distribution trough 321 to rotate and put the fertilizer in the distribution trough 321 into the drop port 313, and the fertilizer slides along the drop port 313 into the fertilization ditch on the ground; at the same time, the distribution plate 32 drives the lifting rod 321 during the rotating distribution process. 3 rotates, and when the ejecting rod 33 passes through the cam 34, the cam 34 presses the end of the ejecting rod 33 upward, so that the ejecting rod 33 extends away from the cam 34 into the material receiving port 312, and presses and shakes the fertilizer in the material receiving port 312 upward, and the distributing plate 32 continues to rotate. The ejecting rod 33 disengages from the cam 34, and moves to the side away from the material receiving port 312, so that the fertilizer collapses downward, thereby facilitating the fertilizer to fall downward into the distributing trough 321 that passes through the material receiving port 312 later; after the fertilizer falls into the fertilizer ditch excavated by the furrowing plow 11, it synchronously drives the vertical shaft 12 to rotate, and the rotation of the vertical shaft 12 drives the scraper 14 to rotate, and the scraper 14 rotates to fill the soil on both sides of the fertilizer ditch onto the fertilizer ditch to cover the fertilizer.
