Abstract

This invention discloses a fully automated vegetable sowing and fertilization integrated device, specifically relating to the technical field of vegetable planting equipment. It includes a sowing frame, two fixed seats, a support, a plow blade, and a plow blade replenishment mechanism. The plow blade replenishment mechanism comprises a replenishment blade, a linkage column, a hinge sleeve, a hinge shaft, a push block, and an electric cylinder. This invention employs a plow blade replenishment mechanism, which has the advantages of allowing the linkage column to move the replenishment blade along an arc-shaped path when a plow blade is damaged. The replenishment blade can replace the damaged plow blade, and the plow blade can be quickly adjusted to replenish plowing according to usage needs, resulting in better adjustable plowing performance. This solves the problem that some plow blades are easily damaged by impact during the grooving process, making it difficult to quickly adjust and replenish plowing according to usage needs, resulting in poor adjustable plowing performance and thus poor durability of the fully automated vegetable sowing and fertilization integrated device.

Description

Technical Field

[0001] This invention relates to the field of vegetable planting equipment technology, and more specifically, to a fully automated integrated vegetable sowing and fertilization equipment. Background Technology

[0002] In vegetable cultivation, sowing and fertilization are two important and tedious steps. Traditional vegetable sowing and fertilization usually rely on manual operation. When sowing manually, it is difficult to maintain uniform spacing and depth of seeds, resulting in uneven seedling emergence and affecting later growth and yield. Manual fertilization is not only labor-intensive, but also difficult to precisely control the amount of fertilizer, easily leading to over-fertilization causing waste and environmental pollution, or under-fertilization affecting vegetable growth.

[0003] Among the existing publicly available documents, patent publication number CN113940161A discloses an integrated sowing and fertilizing agricultural device. This technology uses a belt to drive a transmission turntable in a coaxial linkage to control the material and rotate the turntable. By pulling the adjusting cap, the fixed column is disengaged from the angle adjustment hole, and the height of the seed hopper from the soil is adjusted. The adjusting buckle on the second seed hopper adjusts its sliding on the first seed hopper adjusting rod, thereby adjusting the tilt angle of the seed hopper relative to the soil. Fertilizer is delivered through the fertilizer delivery pipe to achieve an integrated sowing and fertilizing effect. However, this technology has the following drawbacks.

[0004] When vegetables are sown and fertilized in an integrated manner, the soil needs to be trenched using a plow. However, during the trenching process, some cutting points of the plow blades are easily damaged by impacts. It is difficult to quickly adjust the plow blades to replenish the soil according to the needs of use, resulting in poor adjustable plowing performance and thus poor durability of fully automatic vegetable sowing and fertilization integrated equipment. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides the following technical solution: a fully automatic vegetable sowing and fertilization integrated device, comprising a sowing frame, two fixed seats fixedly installed on the lower surface of the sowing frame, a bracket fixedly connected to one side of each fixed seat, a plow blade fixedly connected to one end of each bracket, and a plow blade replenishment mechanism installed inside the plow blade; the plow blade replenishment mechanism includes a replenishment blade slidably installed inside the plow blade, and a linkage column fixedly connected to one side of the replenishment blade; a hinge sleeve rotatably connected to the outer wall of the linkage column, and a hinge shaft rotatably connected to the inner wall of the hinge sleeve at a position away from the linkage column, a push block fixedly connected to one end of the hinge shaft, and an electric cylinder mounted on the upper surface of the push block. The vertical cross-section of the replenishment blade is arc-shaped, and both the outer wall of the replenishment blade and the inner wall of the plow blade are smooth surfaces; the linkage column is slidably connected to the plow blade. The output end of the electric cylinder is fixedly connected to the push block, and the electric cylinder is fixedly connected to the plow blade; the electric cylinder is used to push the push block to move. A limiting ring is provided on one side of the hinge sleeve, and the limiting ring is fixedly connected to the linkage column and slidably connected to the plow blade. Multiple movable wheels are fixedly installed on the outer wall of the sowing frame, and the outer walls of the multiple movable wheels are all smooth surfaces.

[0006] When this technology is used in an integrated manner, if the plow blade is damaged, the electric cylinder pushes the push block to move down, the hinge shaft drives the top of the hinge sleeve to move down, the linkage column drives the limit ring to move down along an arc path, and the supplementary blade moves down along the inside of the plow blade along an arc path.

[0007] Preferably, two rotary motors are fixedly installed at the bottom of the inner wall of the sowing frame. Each rotary motor's output end is fixedly connected to a screw, and each screw's outer wall is threaded with a threaded sleeve. A support plate is installed on one side of each threaded sleeve, and both threaded sleeves are fixedly connected to the support plate. A drive motor is fixedly installed on the upper surface of the support plate, and a gear shaft is fixedly connected to the output end of the drive motor. A chain is meshed and driven through the outer wall of the gear shaft. A movable plate is fixedly installed on one side of the support plate. The support plate and the sowing frame are slidably connected, and the movable plate is also slidably connected to the sowing frame. An auger is fixedly installed on one side of the movable plate, and a drive motor is installed at one end of the auger. The output end of the drive motor is fixedly connected to the auger, and the drive motor is fixedly connected to the movable plate. A storage box is threadedly connected to the top of the auger, and a corrugated pipe is fixedly connected to the bottom of the auger's outer wall. The corrugated pipe is fixedly connected to the movable plate.

[0008] When used in an integrated manner, this technology involves two rotary motors driving the screw to rotate, the threaded sleeve moving the support plate downwards, and the drive motor driving the gear shaft to rotate, thus enabling the chain to move laterally. The transmission is achieved by a drive motor driving an auger, with seeds being discharged through a bellows.

[0009] Preferably, a guide positioning assembly is installed on one side of the push block; the guide positioning assembly includes a sensing block fixedly installed on one side of the push block, a guide sleeve fixedly connected to one side of the sensing block, a sliding column fixedly connected to the top of the guide sleeve, a connecting ring slidably connected to the outer wall of the sliding column, and a support block fixedly installed on one side of the outer wall of the connecting ring, the support block being fixedly connected to the plow blade; a distance sensor fixedly connected to the plow blade is provided above the sensing block. The outer wall of the sliding column and the inner wall of the connecting ring are both smooth surfaces, and the cross-sectional shape of the sliding column is circular.

[0010] When this technology is used in an integrated manner, when the push block moves down, it will drive the guide sleeve block to move down, and the slide column will slide down along the inner wall of the sleeve ring. The sleeve ring stably guides the slide column to move down. The distance sensor senses the distance between the distance sensor and the sensing block. When the distance value sensed by the distance sensor is the same as the set supplementary distance, the electric cylinder is turned off.

[0011] The technical effects and advantages of this invention are as follows:

[0012] 1. This invention employs a plow blade replenishment mechanism. When a plow blade is damaged, an electric cylinder pushes a push block to move downwards. The push block drives the hinge shaft to move downwards, which in turn drives the top of the hinge sleeve to move downwards. The linkage column drives the limiting ring to move downwards along an arc-shaped path, and the linkage column drives the replenishment blade to move downwards along the arc-shaped path. The replenishment blade can replenish the damaged plow blade, and the plow blade can be quickly adjusted and replenished for plowing as needed, resulting in better adjustable plowing performance.

[0013] 2. This invention activates two rotary motors, which drive screws to rotate. The screws drive the threaded sleeves to move downwards under the action of the threaded transmission force. The support plate drives the moving plate to move downwards to the designated position. The drive motor drives the gear shaft to rotate, and the chain can realize lateral movement. The sowing frame drives multiple moving wheels to move, and the bracket drives the plow blade to shovel the soil. Thus, the soil can be shoveled and trenched by the plow blade. This fully automatic vegetable sowing and fertilization operation is integrated, and the vegetable processing efficiency is faster.

[0014] 3. In this invention, the push block moves down through the guide positioning component, which in turn moves the guide sleeve block down, which in turn moves the sliding column down. The plow blade supports the support block, which in turn supports the sleeve ring. The sensing block moves down, and the distance sensor senses the distance between the distance sensor and the sensing block. When the distance value sensed by the distance sensor is the same as the set supplementary distance, the electric cylinder is turned off. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] As attached Figure 1 - Appendix Figure 8The image shows a fully automatic vegetable sowing and fertilization integrated device. This device is equipped with a plow blade replenishment mechanism and a guide positioning component. The arrangement of each mechanism and component enables the linkage column 6 to drive the replenishment blade 5 to move down along an arc-shaped path. The replenishment blade 5 can replenish the damaged plow blade 4. The plow blade can be quickly adjusted and replenished according to the needs of use, resulting in better adjustable plowing performance. The specific structural settings of each mechanism and component are as follows.

[0026] In this technical solution, as shown in the appendix Figure 1 - Appendix Figure 4 As shown, two fixed seats 2 are fixedly installed on the lower surface of the sowing frame 1.

[0028] In this technical solution, as shown in the appendix Figure 1 - Appendix Figure 4 As shown, a limiting ring 11 is provided on one side of the hinge sleeve 7, and the limiting ring 11 is fixedly connected to the linkage column 6. The limiting ring 11 is slidably connected to the plow blade 4 so that the linkage column 6 can drive the limiting ring 11 to move down along an arc path. In this way, the linkage column 6 drives the supplementary blade 5 to move down along an arc path. Multiple moving wheels 12 are fixedly installed on the outer wall of the sowing frame 1. The outer walls of the multiple moving wheels 12 are all smooth surfaces so that the sowing frame 1 can drive the multiple moving wheels 12 to move. The sowing frame 1 drives the fixed seat 2 to move, which facilitates the stable movement of the sowing frame 1.

[0029] In this technical solution, as shown in the appendix Figure 5 - Appendix Figure 7As shown, two rotary motors 13 are fixedly installed at the bottom of the inner wall of the sowing frame 1. Each rotary motor 13 has a screw 14 fixedly connected to its output end. Each screw 14 has a threaded sleeve 15 threadedly connected to its outer wall. A support plate 19 is installed on one side of the threaded sleeve 15. Both threaded sleeves 15 are fixedly connected to the support plate 19.

A chain 18 is meshed and driven through the outer wall of the gear shaft 17. A movable plate 20 is fixedly installed on one side of the support plate 19. The support plate 19 is slidably connected to the sowing frame 1, and the movable plate 20 is also slidably connected to the sowing frame 1.

[0030] A screw conveyor 21 is fixedly installed on one side of the movable plate 20. A drive motor 22 is installed at one end of the screw conveyor 21. The output end of the drive motor 22 is fixedly connected to the screw conveyor 21, and the drive motor 22 is fixedly connected to the movable plate 20. A storage box 23 is threadedly connected to the top of the screw conveyor 21, and a bellows 24 is fixedly connected to the bottom of the outer wall of the screw conveyor 21. The bellows 24 is fixedly connected to the movable plate 20.

[0031] In this technical solution, as shown in the appendix Figure 8 As shown, a guide positioning assembly is installed on one side of the push block 9. The guide positioning assembly includes a sensing block 25 fixedly installed on one side of the push block 9, a guide sleeve block 26 fixedly connected to one side of the sensing block 25, a sliding column 27 fixedly connected to the top of the guide sleeve block 26, a sleeve ring 28 slidably connected to the outer wall of the sliding column 27, and a support block 29 fixedly installed on one side of the outer wall of the sleeve ring 28. A distance sensor 30 fixedly connected to the plow blade 4 is provided above the sensing block 25. The support block 29 is fixedly connected to the plow blade 4. The outer wall of the sliding column 27 and the inner wall of the sleeve ring 28 are both smooth surfaces, and the cross-sectional shape of the sliding column 27 is circular.

[0032] The working principle of this fully automatic vegetable sowing and fertilization integrated equipment is as follows:

[0033] Step 1: During the fully automated vegetable sowing and fertilization operation, two rotary motors 13 are started, each driving a screw 14 to rotate. The screw 14 drives a threaded sleeve 15 to move downwards under the force of the threaded transmission. The threaded sleeve 15 drives a support plate 19 to move downwards, and the support plate 19 drives a moving plate 20 to move downwards to a designated position. Simultaneously, a drive motor 16 drives a gear shaft 17 to rotate, which in turn drives a chain 18 for meshing transmission, enabling the chain 18 to move laterally. Vegetable seeds are poured into a storage box 23, which then enters an auger 21. A drive motor 22 drives the auger 21 for transmission, allowing the vegetable seeds to flow along the auger 21 into a corrugated pipe 24. The seeds are then discharged through the corrugated pipe 24. Simultaneously, the sowing frame 1 drives multiple moving wheels 12 to move, which in turn drives a fixed base 2 to move. The fixed base 2 then drives a support 3 to move, and the support 3 drives a plow blade 4 to shovel the soil, thus creating trenches by the plow blade 4.

[0034] Step 2: When replenishing the plow blades, if the plow blade 4 is damaged, the electric cylinder 10 pushes the push block 9 downwards. The push block 9 drives the hinge shaft 8 downwards, the hinge shaft 8 drives the top of the hinge sleeve 7 downwards, the hinge sleeve 7 drives the linkage column 6 downwards, and the linkage column 6 drives the limit ring 11 downwards along an arc path. In this way, the linkage column 6 drives the replenishing blade 5 downwards along an arc path. The replenishing blade 5 moves downwards along the inside of the plow blade 4 along an arc path, so that the replenishing blade 5 can replenish the damaged plow blade 4.

[0035] Step 3, during the guiding and positioning process, when the push block 9 moves down, it will drive the guide sleeve block 26 to move down, and the guide sleeve block 26 will drive the sliding column 27 to move down. The sliding column 27 slides down along the inner wall of the sleeve ring 28. At the same time, the plow blade 4 supports the support block 29, and the support block 29 supports the sleeve ring 28. The sleeve ring 28 stably guides the sliding column 27 to move down. When the sensing block 25 moves down, the distance sensor 30 senses the distance between the distance sensor 30 and the sensing block 25. When the distance value sensed by the distance sensor 30 is the same as the set supplementary distance, the electric cylinder 10 is turned off. In this way, the supplementary blade 5 can accurately supplement the damaged plow blade 4 inside the plow blade 4.
