Description

Technical Field

[0001] This invention relates to the field of chili seedling technology, specifically to a device for cleaning and covering soil around grapevines. Background Technology

[0002] Grapevines are broad-leaved woody vines. Before the start of winter, as temperatures drop, the leaves gradually fall, stomata close, and the vines enter dormancy to withstand the harsh winter. In northern my country, to prevent frost damage to grapevines, they are commonly laid down and covered with soil. This provides a layer of protection, reducing the damage to the roots and branches from low temperatures, protecting the roots from the cold, and also helping the vines enter dormancy, maintaining their vigorous growth. After the vines are covered with soil for winter, the soil must be removed promptly, otherwise it will affect the yield and quality of the grapes.

[0003] Currently, existing technologies mostly involve digging trenches to remove soil. First, the top layer of soil is manually removed using shovels, and then the second layer is cleared using a small shovel. However, manual labor lacks control over the force applied and cannot achieve the same depth as machines, easily damaging the grapevine roots. Furthermore, the entire process is cumbersome and labor-intensive, resulting in reduced soil removal efficiency. Therefore, a grapevine soil removal device is proposed.

[0004] Chinese Patent No. CN116686439A discloses a soil-covering and cleaning device for grapevines, including a main frame with support legs on its side walls and movable rollers fixedly connected to the bottom of the support legs. Mounting plates are fixedly connected to both sides of the main frame. The device also includes a cleaning assembly and a soil-loosening mechanism. The arrangement of a first motor, a soil-digging shaft, soil-digging impellers, and a gear set allows the soil-digging impellers on both sides to rotate simultaneously in opposite directions, thereby improving the soil-digging effect. The combination of a guide groove, a suction groove, a first shaft, first blades, a second motor, and a second and first rotating wheel creates a strong suction effect within the guide groove, quickly sucking in the soil rolled up by the soil-digging impellers, thus improving the efficiency of soil-covering and cleaning. Furthermore, a soft brush is used to perform a secondary, gentle cleaning of the soil covering the grapevines, thereby enhancing the protection of the vines.

[0005] However, this patent also has the following shortcomings: The cleaning components and loosening mechanisms of this patent are both located at the bottom of the main frame. Grapevine mulch must have a certain thickness and height. Therefore, when the main frame cleans along the mulch ridges of the grapevines, since the cleaning components and loosening mechanisms are both horizontally set, and the mulch ridges of the grapevines are mounds of soil with a certain slope on both sides and a higher middle, the cleaning depth of the cleaning components and loosening mechanisms in this patent is relatively shallow, resulting in poor cleaning effect. In addition, after a long period of mulch cleaning, the soil-digging impeller and the mulch brush stick to the soil. If they are not cleaned in time, it will easily affect the subsequent mulch cleaning work and reduce the service life of the soil-digging impeller and the mulch brush. Summary of the Invention

[0006] The purpose of this invention is to provide a grapevine soil cleaning device, which solves the problems of existing grapevine soil cleaning devices having shallow cleaning depths of cleaning components and loosening mechanisms when cleaning grapevine soil ridges, resulting in poor cleaning effect. Furthermore, the soil-grinding impeller and soil-covering soft brush become stuck with soil after a long period of soil cleaning, which can easily affect subsequent soil cleaning work if not cleaned in time.

[0007] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0008] A grapevine soil-covering cleaning device includes a frame, with electric push rods at the four corners of the bottom of the frame. All output ends of the electric push rods are fixedly connected to pulleys. A mounting frame is located at the bottom of the frame, with side plates fixedly connected to both sides of the outer wall of the mounting frame. The output ends of the electric push rods penetrate the side plates and are fixedly connected to them. A partition plate is vertically arranged in the middle of the inner wall of the mounting frame, dividing the frame into two accommodating cavities. Each of the two accommodating cavities contains a cleaning mechanism, which is arranged opposite to each other. Each cleaning mechanism includes a baffle, a soil-scraping component for removing soil covering the grapevines, a sweeping component for cleaning the soil covering the grapevines, and two first cleaning components and two second cleaning components for cleaning the soil-scraping component and the sweeping component, respectively. The baffle is horizontally arranged inside the accommodating cavity and fixedly connected to the partition plate and the mounting frame. The soil-scraping component and the sweeping component are respectively arranged on both sides of the baffle, and the two first cleaning components and the two second cleaning components are symmetrically arranged on both sides of the soil-scraping component and the sweeping component.

[0009] As a preferred embodiment of the present invention, the outer side of the mounting frame is provided with a first driving component for driving the soil-scraping component to rotate and a second driving component for driving the sweeping component to rotate. Both sides of the inside of the frame are provided with a soil discharge mechanism for discharging the soil that has entered the receiving cavity. Both sides of the frame are provided with a discharge port.

[0010] As a preferred embodiment of the present invention, the soil-shoveling assembly includes two first rotating rods and two helical blades. The two first rotating rods are inclinedly arranged in the receiving cavity and are parallel to each other. One end of each of the two first rotating rods is rotatably connected to the partition plate through a bearing. The other end of each of the two first rotating rods passes through the mounting frame and is connected to the first driving assembly. The two helical blades are respectively fixedly installed on the two first rotating rods.

[0011] The two first rotating rods rotate in opposite directions, and the diameter of the spiral blade gradually decreases along the length of the first rotating rod. The diameter of the spiral blade near the mounting frame is larger than the diameter near the partition plate, and the outer ring of the spiral blade is made of rubber material.

[0012] In a preferred embodiment of the present invention, the outer ring at the front end of the helical blade is made of rubber material, and the outer ring at the rear end of the helical blade is toothed.

[0013] In a preferred embodiment of the present invention, the cleaning assembly includes two second rotating rods and two cleaning brushes. The two second rotating rods are symmetrically arranged in the receiving cavity and are staggered in height. Both ends of each second rotating rod are rotatably connected to a partition plate and a mounting frame, respectively. The two cleaning brushes are fixedly mounted on the two second rotating rods.

[0014] In a preferred embodiment of the present invention, the first cleaning component includes a fixed plate, an L-shaped rotating plate, a rotating shaft, several protrusions and several springs, and a drive motor. The fixed plate is fixedly mounted on the inner side wall of the mounting frame. The rotating shaft is located above the fixed plate, and one end of the rotating shaft is rotatably connected to a partition plate via a bearing. The other end of the rotating shaft passes through the mounting frame and is fixedly connected to the output shaft of the drive motor. The drive motor is mounted on the outer side wall of the mounting frame. The L-shaped rotating plate is fixedly sleeved on the rotating shaft. Several mounting holes are provided on the fixed plate. All the protrusions are slidably disposed in all the mounting holes one by one. All the springs are fixedly disposed at the bottom of all the protrusions one by one, and the bottom of all the springs is fixed in the mounting holes.

[0015] As a preferred embodiment of the present invention, the second cleaning component has the same structure as the first cleaning component, the two first cleaning components are respectively disposed on both sides of the two spiral blades, and the two second cleaning components are respectively disposed on both sides of the two cleaning brushes.

[0016] As a preferred embodiment of the present invention, the L-shaped rotating plate includes a sleeve, a horizontal plate, and a cleaning brush. The sleeve is fixedly sleeved on the rotating shaft. The horizontal plate and the cleaning brush are respectively fixed on both sides of the outer wall of the sleeve. The included angle between the horizontal plate and the cleaning brush is set at 90 degrees. When the horizontal plate rotates to above the fixed plate, it abuts against all the protrusions. When the cleaning brush rotates to be parallel to the fixed plate, it can abut against the spiral blades or the cleaning brush. The two cleaning brushes located on both sides of the two spiral blades are trapezoidal. The two cleaning brushes located on both sides of the two cleaning brushes are steel combs and are parallelograms.

[0017] As a preferred embodiment of the present invention, a protective cover is fixedly connected between the bottom of the frame and the ends of the mounting frame and the partition plate.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] (1) By tilting the first rotating rod, the soil-scraping components in the two cleaning mechanisms are arranged in a "figure-eight" shape, which can better fit the conical protrusion of the soil ridge. Compared with the horizontally arranged soil-scraping impeller in the prior art, the spiral blades in the present invention can avoid the soil-buried position of the grapevine branches during cleaning, thus avoiding the grapevines being scratched by the spiral blades.

[0020] (2) By setting the outer ring of the spiral blade tail end to be toothed, the invention can break up the soil ridge when the spiral blade rotates, preventing the soil from being too hard and affecting the effect of soil removal. The head end of the spiral blade is close to the grapevine. Therefore, the rubber of the outer ring of the spiral blade head end can gently clean the soil close to the grapevine, avoiding damage to the main stem of the grapevine, improving the protection effect of the grapevine, realizing the automated removal of soil, and achieving the ideal vine digging effect without damaging the grapevine, greatly improving the efficiency of vine digging.

[0021] (3) By setting up the cleaning components, the present invention can perform secondary flexible cleaning on the soil covering the grapevine branches, which is more thorough and has a better cleaning effect, thereby greatly improving the cleaning efficiency.

[0022] (4) By setting up the first cleaning component and the second cleaning component, the present invention can ensure that the spiral blades are always in contact with the cleaning brush according to the characteristics of the soil-scraping component and the sweeping component. The cleaning brush is set so that it can reach into the toothed recess of the outer ring of the spiral blade head for cleaning, and can also avoid scratching the outer ring of the rubber material at the tail end of the spiral blade. The cleaning brush in the second cleaning component is set with a steel comb, which can ensure that when the cleaning brush comes into contact with the cleaning brush, the soil on the cleaning brush can be scraped off, and targeted cleaning can be carried out to improve the cleaning effect, increase the cleaning efficiency, and reduce the cost of use.

[0031] 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.

[0032] like Figures 1 to 7As shown, this invention provides a grapevine soil covering and cleaning device, including a frame 1. Electric push rods 2 are installed at the four corners of the bottom of the frame 1, and pulleys 3 are fixedly connected to the output ends of all electric push rods 2. A mounting frame 4 is installed at the bottom of the frame 1, and side plates 41 are fixedly connected to both sides of the outer wall of the mounting frame 4. The output ends of the electric push rods 2 penetrate through the side plates 41 and are fixedly connected to them. A partition plate 42 is vertically installed in the middle of the inner wall of the mounting frame 4, dividing the mounting frame 4 into two receiving cavities. A cleaning mechanism 43 is installed inside each of the two receiving cavities, and the two cleaning mechanisms 43 are arranged opposite to each other. The cleaning mechanism 43 includes a baffle 44, a soil-scraping component 45 for removing soil covering the grapevines, a cleaning component 46 for sweeping away soil covering the grapevines, and two first cleaning components 47 and two second cleaning components 48 for cleaning the soil-scraping component 45 and the cleaning component 46 respectively. The baffle 44 is horizontally arranged inside the receiving cavity and is fixedly connected to the partition plate 42 and the mounting frame 4. The soil-scraping component 45 and the cleaning component 46 are respectively arranged on both sides of the baffle 44, and the two first cleaning components 47 and the two second cleaning components 48 are symmetrically arranged on both sides of the soil-scraping component 45 and the cleaning component 46.

[0033] The outer side of the mounting frame 4 is provided with a first drive assembly 5 for driving the soil-scraping assembly 45 to rotate and a second drive assembly 6 for driving the sweeping assembly 46 to rotate. Both sides of the inside of the frame 1 are provided with a soil discharge mechanism 7 for discharging the soil that has entered the receiving cavity. Both sides of the frame 1 are provided with a discharge port 8.

[0034] When cleaning the soil covering the grapevines, the workers push the frame 1 along the ridge of soil covering the grapevines and use four electric push rods 2 to drive the two side plates 41 to rise and fall, thereby adjusting the height of the mounting frame 4. This allows the cleaning mechanism 43 installed inside the mounting frame 4 to rise and fall, ensuring that the bottom of the two cleaning mechanisms 43 is always close to and in contact with the soil covering the grapevines, and cleans it. The number of first drive components 5 is set according to the number of soil-digging components 45. By driving the first drive components 5, the two soil-digging components 45 are driven to rotate, thereby causing the two soil-digging components 45 to roll away the soil covering the grapevines. The soil-digging component 45 includes two first rotating rods 451 and two spiral blades 452. The two first rotating rods 451 are inclined and parallel to each other in the receiving cavity. One end of each of the two first rotating rods 451 is rotatably connected to the partition plate 42 through a bearing. The other end of each of the two first rotating rods 451 passes through the mounting frame 4 and is connected to the first drive components 5. The two spiral blades 452 are respectively fixedly installed on the two first rotating rods 451.

[0035] The two first rotating rods 451 rotate in opposite directions, and the diameter of the spiral blade 452 gradually decreases along the length of the first rotating rod 451. The diameter of the spiral blade 452 on the side closer to the mounting frame 4 is larger than the diameter on the side closer to the partition plate 42. The outer ring of the spiral blade 452 is made of rubber material.

[0036] Two first drive components 5 drive four first rotating rods 451 in two cleaning mechanisms 43 to rotate synchronously, thereby driving all the spiral blades 452 to rotate in opposite directions. When the spiral blades 452 rotate, they can crush the soil ridges and spin the soil out of the grapevines. Subsequently, the soil is conveyed upward by the spiral blades 452, and after being adsorbed by the soil discharge mechanism 7, it is discharged from the discharge port 8. The soil discharge mechanism 7 in this invention can be an adsorption pump or other equipment and mechanisms that can achieve this function. Among them, the two first rotating rods 451... The inclined arrangement of 51 allows the crushed soil to be conveyed upward along the inclined direction by the spiral blade 452. Furthermore, due to the inclined arrangement of the first rotating rod 451, the soil-digging components 45 in the two cleaning mechanisms 43 are arranged opposite each other to form a "figure-eight" shape, which can better fit the conical protrusion of the soil mound. Compared with the horizontally arranged soil-digging impeller in the prior art, the spiral blade 452 in this invention can avoid the buried position of the grapevine branches during cleaning, thus preventing the grapevine from being scratched by the spiral blade 452.

[0037] It is worth noting that since the two first rotating rods 451 rotate in opposite directions, when the first drive assembly 5 drives the two first rotating rods 451 to rotate in opposite directions, it can drive the two spiral blades 452 to rotate and push the soil from both sides to the middle of the two spiral blades 452, so that the soil is concentrated directly below the soil discharge mechanism 7, and the soil discharge mechanism 7 can better adsorb and discharge the soil. Furthermore, the outer ring at the front end of the spiral blade 452 is made of rubber material, and the outer ring at the tail end of the spiral blade 452 is toothed. Furthermore, since the diameter of the spiral blade 452 near the mounting frame 4 is larger than the diameter near the partition plate 42, its tail end contacts the soil first when the spiral blade 452 rotates. Therefore, the outer ring of the tail end of the spiral blade 452 is set as toothed, so that it can break up the soil ridges when the spiral blade 452 rotates, preventing the soil from being too hard and affecting the effect of soil removal, which is conducive to the further progress of the cleaning work. The head end of the spiral blade 452 is closer to the grapevine, so its outer ring is set as rubber, which can bend when it comes into contact with the soil, thereby rolling up the broken soil. As the first rotating rod 451 rotates, the rolled-up soil is transported upward. The rubber of the outer ring of the head end of the spiral blade 452 provides flexible cleaning of the soil near the grapevine, avoiding damage to the main stem of the grapevine and improving the protection effect of the grapevine. This invention realizes the automated removal of soil, and at the same time achieves the ideal vine digging effect without damaging the grapevine, greatly improving the efficiency of vine digging.

[0038] A protective cover 9 is fixedly connected between the bottom of the frame 1 and the ends of the mounting frame 4 and the partition plate 42. The protective cover 9 can be made of corrugated pipe made of rubber or other soft materials, so that the top of the frame 1 and the mounting frame 4 are sealed, so that the adsorption effect of the soil discharge mechanism 7 is not affected when the electric push rod 2 drives the mounting frame 4 to rise and fall.

[0039] The soil in the soil mound is largely removed by the soil-digging component 45, but a small amount of soil remains embedded in the grapevine branches. Therefore, after the soil-digging component 45 has removed a large amount of soil, the remaining soil on the grapevine branches is swept away by the sweeping component 46. The sweeping component 46 includes two second rotating rods 461 and two cleaning brushes 462. The two second rotating rods 461 are symmetrically arranged in the receiving cavity, and the two second rotating rods 461 are staggered at different heights. Both ends of each second rotating rod 461 are rotatably connected to the partition plate 42 and the mounting frame 4, respectively. The two cleaning brushes 462 are fixedly installed on the two second rotating rods 461. After the soil-scraping component 45 removes a large amount of topsoil, the grapevines are exposed to the air. As the frame 1 moves, the grapevines move under the sweeping component 46. At this time, the two second drive components 6 drive all the second rotating rods 461 in the two cleaning mechanisms 43 to rotate, thereby causing all the second rotating rods 461 to drive the cleaning brushes 462 on their outer walls to rotate, thus sweeping away the topsoil on the grapevines. It is worth noting that because the two second rotating rods 461 are staggered at different heights, the two cleaning brushes 462 at the bottom are... 62 first contacts the soil, and the rotation of the second rotating rod 461 drives the two cleaning brushes 462 to sweep away the soil near the sides of the grapevine branches, thereby increasing the speed of the soil falling. The two cleaning brushes 462 at the top are closely spaced and surround the sides of the grapevine branches. As the cleaning brushes 462 rotate, the soil on the grapevine branches is also gradually swept away. Through the setting of the cleaning component 46, a secondary gentle cleaning can be performed on the soil near the grapevine branches, making the cleaning more thorough and the cleaning effect better, thus greatly improving the cleaning efficiency.

[0040] Regardless of whether it's the soil-digging component 45 or the sweeping component 46, soil will adhere to the spiral blades 452 and cleaning brushes 462 after prolonged soil cleaning. Soil adhesion can reduce the cleaning effect. Furthermore, disassembling and cleaning these components during the soil cleaning process is inconvenient, and frequent manual cleaning will also affect the efficiency of the grapevine soil cleaning work. Therefore, this invention provides a first cleaning component 47 and a second cleaning component 48 on both sides of the soil-digging component 45 and the sweeping component 46, respectively. This allows the device to promptly clean the soil adhering to the spiral blades 452 and cleaning brushes 462 after a period of operation, thereby improving the soil cleaning effect. The first cleaning component 47 includes a fixed plate 471 and an L-shaped rotating plate 472. The mounting frame 4 consists of a rotating shaft 473, several protrusions 474, several springs 475, and a drive motor. A fixing plate 471 is fixedly mounted on the inner side wall of the mounting frame 4. The rotating shaft 473 is located above the fixing plate 471, and one end of the rotating shaft 473 is rotatably connected to the partition plate 42 through a bearing. The other end of the rotating shaft 473 passes through the mounting frame 4 and is fixedly connected to the output shaft of the drive motor. The drive motor is mounted on the outer side wall of the mounting frame 4. An L-shaped rotating plate 472 is fixedly sleeved on the rotating shaft 473. Several mounting holes 477 are provided on the fixing plate 471. All protrusions 474 are slidably disposed in all mounting holes 477. All springs 475 are fixedly disposed at the bottom of all protrusions 474. The bottom of all springs 475 is fixed in the mounting holes 477.

[0041] The second cleaning component 48 has the same structure as the first cleaning component 47. The two first cleaning components 47 are respectively disposed on both sides of the two spiral blades 452, and the two second cleaning components 48 are respectively disposed on both sides of the two cleaning brushes 462.

[0042] Initially, the L-shaped rotating plate 472 is vertical to prevent it from interfering with the cleaning of the spiral blades 452. When cleaning of the spiral blades 452 is required, the drive motor rotates the rotating shaft 473, causing the L-shaped rotating plate 472 to rotate from a vertical position towards the spiral blades 452 to a horizontal position. The L-shaped rotating plate 472 includes a sleeve 478, a horizontal plate 479, and a cleaning brush 480. The sleeve 478 is fixedly fitted onto the rotating shaft 473, and the horizontal plate 479 and cleaning brush 480 are... The 0 are fixed on both sides of the outer wall of the sleeve 478. The included angle between the horizontal plate 479 and the cleaning brush 480 is set at 90 degrees. When the horizontal plate 479 rotates to above the fixed plate 471, it abuts against all the protrusions 474. When the cleaning brush 480 rotates to be parallel with the fixed plate 471, it can abut against the spiral blade 452 or the cleaning brush 462. The two cleaning brushes 480 located on both sides of the two spiral blades 452 are trapezoidal. The two cleaning brushes 480 located on both sides of the two cleaning brushes 462 are steel combs and are parallelograms.

[0043] Subsequently, the first drive assembly 5 is activated, and the soil-scraping assembly 45 is started, causing the spiral blade 452 to rotate. When the spiral blade 452 rotates and contacts the cleaning brush 480, the cleaning brush 480 sweeps away the soil adhering to the spiral blade 452. After cleaning, the L-shaped rotating plate 472 is reset. At this time, the horizontal plate 479 rotates from a vertical state to a horizontal state and strikes multiple protrusions 474. The collision between the horizontal plate 479 and the protrusions 474 causes vibration, thereby shaking off the soil on the cleaning brush 480. It is worth noting that the second cleaning assembly 48 in this invention has the same structure as the first cleaning assembly 47, but in order to adapt to the installation positions of the spiral blade 452 and the cleaning brush 462, their installation positions are different. Similarly, the cleaning brush 462 can be cleaned by driving the second cleaning assembly 48. The difference is that, since the diameter of the spiral blade 452 gradually increases along the length direction of the first rotating rod 451, the cleaning brush 462 can be cleaned. As the diameter of the spiral blade 452 decreases, the diameter of the side of the spiral blade 452 closest to the mounting frame 4 is larger than the diameter of the side closest to the partition plate 42. Therefore, the cleaning brush 480 is set as a trapezoidal brush, which can adapt to the spiral blade 452 as the blade size decreases, so that the spiral blade 452 can always be in contact with the cleaning brush 480. The setting of the cleaning brush 480 allows it to reach into the toothed recess of the outer ring of the head end of the spiral blade 452 for cleaning, while avoiding scratching the outer ring of the rubber material at the tail end of the spiral blade 452. Unlike the first cleaning assembly 47, since the cleaning brush 462 is a soft brush, the cleaning brush 480 in the second cleaning assembly 48 is set as a hard steel comb, and is set as a parallelogram according to the shape of the cleaning brush 462, so as to ensure that the soil on the cleaning brush 462 can be scraped off when the cleaning brush 462 comes into contact with the cleaning brush 480. The parallelogram cleaning brush 480 fits the bristles of the cleaning brush 462 better. The drive motor used to drive the rotating shaft 473 is existing technology, so it is not shown in the figure and will not be described in detail. The cleaning component of the present invention has a simple structure and can perform targeted cleaning according to the characteristics of the soil-scraping component 45 and the sweeping component 46, so as to improve the cleaning effect, increase the cleaning efficiency, and reduce the cost of use.
