[0001] This invention belongs to the technical field of soil seed bank remediation, specifically relating to a seed replenishment device for soil seed bank remediation. Background Technology

[0002] Soil seed banks play a vital role in vegetation restoration. They are not only the foundation for plant population renewal but also provide seed sources after environmental changes or disturbances, helping ecosystems recover rapidly. Seed bank research is an important part of ecological restoration and vegetation restoration and is currently a hot topic in ecological restoration research. Seed sowing and replenishment devices are used in the process of soil seed bank restoration to replenish seeds. Ecological restoration through planting on wasteland and making good use of artificial seed banks have positive significance for restoring damaged ecosystems and are an important prerequisite for achieving sustainable development.

[0003] Problems with existing technology: 1. Existing seed replenishment devices for seed bank restoration are mostly limited in function. During seed replenishment, the amount of seeds replenished per sowing is usually fixed and difficult to adjust according to actual conditions.

[0004] 2. Existing seed replenishment devices for seed bank restoration are mostly cumbersome to operate, requiring the coordination of multiple processes to achieve the seed sowing and replenishment process, which in turn requires the use of various mechanical equipment, resulting in low seed sowing and replenishment efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a seed replenishment device for soil seed bank remediation, which can solve the problem that existing seed replenishment devices for seed bank remediation are mostly limited in function and the amount of seeds replenished per sowing is mostly fixed, making it difficult to adjust according to actual conditions.

[0006] The specific technical solution adopted by this invention is as follows: A seed replenishment device for soil seed bank remediation includes a pusher frame.

[0009] The upper end of the mounting frame is fixedly connected to two feeding pipes. The upper ends of the two feeding pipes are fixedly connected to the quantitative feeding component. The lower ends of the two feeding pipes are respectively sleeved with four grounding sleeves, and the relatively close ends of the corresponding two grounding sleeves overlap. The relatively far ends of the four grounding sleeves are respectively fixedly connected to two mounting slide plates. The two mounting slide plates are slidably connected to two support cross plates through square through grooves opened inside them.

[0010] The left and right ends of the two supporting horizontal plates are respectively fixedly connected to the left and right sides inside the mounting frame. The upper ends of the two supporting horizontal plates are fixedly connected to the fixed shafts. The upper ends of the two fixed shafts are movably connected to the gears. The gears mesh with four L-shaped toothed plates respectively. The lower ends of the four L-shaped toothed plates are fixedly connected to the upper ends of the two mounting slides respectively. The left end of the left mounting slide is fixedly connected to two electric push rods. The two electric push rods are fixedly connected to the left end of the mounting frame.

[0011] The quantitative feeding assembly includes two housings. The lower ends of the two housings are fixedly connected to the upper ends of the mounting frame. The lower ends of the two housings are respectively fixedly connected to the upper ends of two feeding pipes. The upper ends of the two housings are fixedly connected to feeding hoses. The upper ends of the two feeding hoses are fixedly connected to the seed storage box. The front and rear ends of the two housings are respectively movably connected to the front and rear ends of two feeding rollers. The two feeding rollers are respectively inserted into two adjusting blocks through feeding grooves opened inside their upper ends.

[0012] The rear ends of the two adjusting blocks pass through the rear ends of the two feeding rollers and are fixedly connected to the two I-shaped rotating blocks. The two I-shaped rotating blocks are fixedly connected to the two rotating sleeves. The two rotating sleeves are movably connected to the rotating rod II, which is provided with four guide blocks, through two guide grooves opened inside them. The rotating rod II is fixedly connected to the two feeding rollers, each of which has a circular through hole inside. Gear II is fixedly connected to both the front and rear ends of the rotating rod II.

[0013] The two gears mesh with two meshing gear plates respectively. Each of the two I-shaped rotating blocks is movably connected to a connecting plate. Each of the two connecting plates is threadedly connected to two threaded sleeves through threaded holes opened inside their left ends. Each of the two threaded sleeves is fixedly connected to a rotating rod. Two L-shaped plates are movably connected to the rotating rod. The lower ends of the two L-shaped plates are fixedly connected to the mounting frame. The two L-shaped plates are fixedly connected to the front and rear sides of a limiting rod. The limiting rod is slidably connected to two connecting plates, each with a limiting hole inside.

[0014] The soil loosening component includes a dustproof shell. The upper side of the dustproof shell is fixedly connected to the lower ends of four electric push rods and four limiting rods.

The lower ends of the two fixed plates are fixedly connected to the upper end of the dustproof shell.

[0016] The technical effects achieved by this invention are as follows: 1. This invention, through the interaction of the meshing toothed plate and gear two, enables the rotating rod two to rotate during each downward movement of the sowing component. This, in turn, causes the two feeding rollers to rotate half a turn inside the two housings. At this time, the seeds inside the feeding troughs located inside the feeding rollers can fall between the corresponding two insertion sleeves through the feeding pipe as the feeding rollers rotate, ensuring the uniformity of seed replenishment each time. The interaction of the rotating rod one, threaded sleeve, connecting plate, limiting rod three, and I-shaped rotating block can change the position of the adjusting block inside the corresponding feeding trough, thereby adjusting the size of the space inside the corresponding feeding trough. This allows the device to conveniently adjust the amount of seeds replenished per sowing according to different sowing conditions.

[0017] 2. This invention, through the coordinated arrangement of an electric push rod II, a limiting rod II, a dual-axis motor, a rotating rod III, a transmission wheel II, and a transmission wheel I, can drive the loosening blade wheel to rotate. This achieves soil loosening before sowing, making the soil finer and more fluffy, facilitating the growth of seeds after sowing. The coordinated arrangement of the electric push rod III, the L-shaped toothed plate, the gear I, the fixed shaft, and the supporting cross plate allows the two mounting plates to move away from each other after the insertion sleeve is inserted to a suitable depth in the soil. This, in turn, moves the corresponding two insertion sleeves away from each other, expanding the soil around the insertion sleeves. Simultaneously, it allows seeds located between the two insertion sleeves to fall smoothly into the expanded soil, thus completing the seed sowing process. Attached Figure Description

[0020] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0021] like Figure 1-9 As shown, a seed replenishment device for soil seed bank remediation includes a pusher frame 1. Four electric push rods 3 are fixedly connected to the right side of the pusher frame 1. The lower ends of the four electric push rods 3 are all fixedly connected to a sowing component 4. The left and right ends of the sowing component 4 are slidably connected to four limiting rods 2. A quantitative feeding component 6 is provided at the upper end of the sowing component 4. The upper end of the quantitative feeding component 6 is fixedly connected to a seed storage box 11. The front and rear ends of the quantitative feeding component 6 are respectively engaged with two meshing toothed plates 5. Four electric push rods 9 are fixedly connected to the left side of the pusher frame 1. The lower ends of the four electric push rods 9 are all fixedly connected to a soil loosening component 7. Four limiting rods 8 are fixedly connected to the upper side of the soil loosening component 7. By setting... The electric push rod 3 drives the sowing component 4 downward, which in turn drives the quantitative feeding component 6 downward. During the downward movement of the quantitative feeding component 6, the meshing tooth plate 5 ensures that the seeds inside the seed storage box 11 are evenly and quantitatively fed into the sowing component 4. The sowing component 4 then completes the seed replenishment process. The limiting rod 2 increases the stability of the sowing component 4 during its movement. The electric push rod 9 drives the soil loosening component 7 downward a certain distance, facilitating the loosening of the soil and the subsequent seed replenishment process.

[0022] Furthermore, the upper ends of the two meshing toothed plates 5 are fixedly connected to the pusher frame 1, and the left and right ends of the seed storage box 11 are fixedly connected to two L-shaped fixing brackets 10. The lower ends of the four L-shaped fixing brackets 10 are fixedly connected to the pusher frame 1. The upper end of the seed storage box 11 is provided with a box cover. The upper ends of the four limiting rods 1 are fixedly connected to the pusher frame 1, and the four limiting rods 2 are movably connected to the pusher frame 1, which has four limiting holes in its upper end. The L-shaped fixing brackets 10 can fix the seed storage box 11. The combination of the limiting rods 2 and the pusher frame 1 can increase the stability of the loosening component 7 during movement.

[0023] Furthermore, the seeding component 4 includes a mounting frame 41. Two limiting plates 49 are fixedly connected to both the left and right ends of the mounting frame 41. The upper ends of the four limiting plates 49 are respectively fixedly connected to the lower ends of four electric push rods 3. Each of the four limiting plates 49 is slidably connected to four limiting rods 2 through internal limiting holes. The upper end of the mounting frame 41 is fixedly connected to the quantitative feeding component 6. Two feeding pipes 410 are fixedly connected to the upper end of the mounting frame 41. The upper ends of both feeding pipes 410 are fixedly connected to the quantitative feeding component 6. The lower end of pipe 410 is respectively sleeved with four grounding sleeves 46, and the relatively close ends of two corresponding grounding sleeves 46 overlap. The relatively far ends of the four grounding sleeves 46 are respectively fixedly connected to two mounting slide plates 43. The two mounting slide plates 43 are slidably connected to two supporting horizontal plates 42 through square through grooves opened inside them. The left and right ends of the two supporting horizontal plates 42 are respectively fixedly connected to the left and right sides inside the mounting frame 41. The upper ends of the two supporting horizontal plates 42 are fixedly connected to fixed shafts 48, and the upper ends of the two fixed shafts 48 are movably connected to... There are two gears 45, which mesh with four L-shaped toothed plates 44 respectively. The lower ends of the four L-shaped toothed plates 44 are fixedly connected to the upper ends of two mounting slide plates 43 respectively. Two electric push rods 47 are fixedly connected to the left end of the left mounting slide plate 43. Both electric push rods 47 are fixedly connected to the left end of the mounting frame 41. The stability of the mounting frame 41 during movement can be increased by the cooperation of the limiting plate 49 and the limiting rod 2. By activating the four electric push rods 3 and cooperating with the four limiting plates 49, the mounting frame 41 is driven. Moving downwards allows the four insertion sleeves 46 to be inserted into the soil to a suitable depth. Then, by activating the two electric push rods 47, the left mounting plate 43 is moved to the left. With the cooperation of the gear 45, L-shaped toothed plate 44, and support plate 42, the right mounting plate 43 is moved to the right. This causes the corresponding two insertion sleeves 46 to move away from each other, allowing the seeds inside the corresponding two insertion sleeves to fall into the expanded sowing pit, thus completing the seed sowing replenishment process.

[0024] The quantitative feeding assembly 6 includes two housings 66. The lower ends of both housings 66 are fixedly connected to the upper ends of the mounting frame 41. The lower ends of the two housings 66 are respectively fixedly connected to the upper ends of two feeding pipes 410. The upper ends of the two housings 66 are each fixedly connected to a feeding hose 610. The upper ends of the two feeding hoses 610 are each fixedly connected to the seed storage box 11. The front and rear ends of the two housings 66 are respectively movably connected to the front and rear ends of two feeding rollers 67. The two feeding rollers 67 are respectively inserted into two adjusting blocks 612 through feeding grooves opened inside their upper ends. The rear ends of the two adjusting blocks 612 pass through the rear ends of the two feeding rollers 67 and are respectively connected to two I-shaped rotating blocks 61. 3. Fixed connection: Two I-shaped rotating blocks 613 are fixedly connected to two rotating sleeves 611 respectively. Each rotating sleeve 611 is movably connected to a rotating rod 68 with four guide blocks on it via two guide grooves inside. The rotating rod 68 is fixedly connected to two feeding rollers 67, each with a circular through hole inside. Gears 69 are fixedly connected to both ends of the rotating rod 68. The two gears 69 mesh with two meshing gear plates 5 respectively. Connecting plates 63 are movably connected to each of the two I-shaped rotating blocks 613. Each connecting plate 63 is threadedly connected to two threaded sleeves 64 via threaded holes on its left end. The two threaded sleeves 613... 4 are all fixedly connected to the rotating rod 61. Two L-shaped plates 65 are movably connected to the rotating rod 61. The lower ends of the two L-shaped plates 65 are fixedly connected to the mounting frame 41. The two L-shaped plates 65 are fixedly connected to the front and rear sides of the limiting rod 62 respectively. The limiting rod 62 is slidably connected to two connecting plates 63, each with a limiting hole inside. During the downward movement of the sowing component 4, the gear 69 and the meshing toothed plate 5 can drive the rotating rod 68 to rotate. The rotation of the rotating rod 68 can drive the two quantitative feeding rollers 67 to rotate accordingly until the two quantitative feeding rollers 67 rotate half a turn. At this time, the two quantitative feeding rollers 67 rotate half a turn. Seeds inside the feeding trough at the upper end of the feeding roller 67 can fall through the feeding pipe 410 between the two corresponding insertion sleeves 46, ensuring the uniformity of seed sowing and replenishment. By rotating the first rotating rod 61, the two threaded sleeves 64 are rotated, which in turn drives the two connecting plates 63 to move in the front and back direction. At this time, the two corresponding I-shaped rotating blocks 613 are moved accordingly, thereby adjusting the position of the two adjusting blocks 612 in the feeding troughs opened inside the upper end of the two feeding rollers 67, thus achieving the effect of adjusting the feeding amount during the seed sowing and replenishment process. The limiting rod 62 can increase the stability of the connecting plate 63 during the movement process.

[0025] The soil loosening assembly 7 includes a dustproof housing 71. The upper side of the dustproof housing 71 is fixedly connected to the lower ends of four electric push rods 9 and four limiting rods 8. A dual-axis motor 77 is fixedly mounted on the upper end of the dustproof housing 71. The dual-axis motor 77 is fixedly connected to one end of two rotating rods 76 via two output shafts. The other end of each rotating rod 76 is fixedly connected to a transmission wheel 74. The two transmission wheels 74 are connected to two transmission wheels 72 via two transmission belts. The two transmission wheels 72 are fixedly connected to the front and rear ends of a soil loosening cutter wheel 73. The front and rear sides of the soil loosening cutter wheel 73 are movably connected to the front and rear ends of the dustproof housing 71. Each rotating rod 76 is movably connected to a fixing plate 75. The lower ends of the two fixing plates 75 are fixedly connected to the upper end of the dustproof shell 71. The rotation of the output shaft of the dual-axis motor 77 drives the two rotating rods 76 to rotate. In turn, with the cooperation of the transmission wheel 74 and the transmission wheel 72, the loosening blade 73 can be driven to rotate. The rotation of the loosening blade 73 can achieve the process of loosening the soil, which is convenient for the subsequent sowing and replenishment of seeds. The cooperation of the limiting rod 8 and the push frame 1 can increase the stability of the dustproof shell 71 during movement. The dustproof shell 71 can prevent soil from splashing during the loosening process.

[0026] The working principle of this invention is as follows: When using this device to replenish seeds during the soil seed bank remediation process, first move the device to a suitable position. Then, start the dual-shaft motor 77 to drive the two rotating rods 76 to rotate. With the cooperation of the transmission wheels 74 and 72, the loosening blades 73 are rotated. At this point, start the four electric push rods 79 to move the loosening assembly 7 downwards a certain distance. The rotation of the loosening blades 73 on the loosening assembly 7 then loosens the soil. After loosening, turn off the dual-shaft motor 77 and start the electric push rods 79 to move the loosening assembly 7 upwards until... Reset, and then start the four electric push rods 3 to drive the sowing component 4 to move downward, thereby driving the four insertion sleeves 46 on the sowing component 4 to be inserted into the loosened soil. During the downward movement of the sowing component 4, the gear 69 and the meshing tooth plate 5 can drive the rotating rod 68 to rotate. The rotation of the rotating rod 68 can drive the two feeding rollers 67 to rotate as well. When the two feeding rollers 67 rotate half a turn, the seeds inside the feeding troughs opened inside the two feeding rollers 67 can fall through the feeding pipe 410 between the corresponding two insertion sleeves 46. Then, the two electric push rods 47 are activated to move the left mounting plate 43 to the left. This, in conjunction with the gear 45 and L-shaped toothed plate 44, moves the right mounting plate 43 to the right. This causes the two mounting plates 43 to move further apart, which in turn moves the corresponding two planting sleeves 46 further apart, thus expanding the soil around the planting sleeves 46. As the two planting sleeves 46 move further apart, the seeds in the middle can fall into the expanded soil, thus completing the sowing process. After sowing is complete, the electric push rods 47 and the electric... The device can be reset by moving the push rod 3. By continuously repeating the above operation steps, the seed sowing and replenishment process can be continuously realized. When it is necessary to adjust the amount of seeds sown at one time during the use of the device, the two threaded sleeves 64 are rotated by rotating the rod 61. Then, under the action of the limiting rod 62, the two connecting plates 63 are moved in the front and back direction. At this time, with the cooperation of the two I-shaped rotating blocks 613, the position of the two adjusting blocks 612 inside the feeding groove opened on the two feeding rollers 67 can be adjusted, thereby achieving the adjustment of the amount of seeds sown at one time.

[0027] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
