Description

Technical Field

[0001] This invention relates to the field of radish harvesting equipment technology, and in particular to an automatic radish harvesting device. Background Technology

[0002] Large-scale radish cultivation relies heavily on manual harvesting, which is time-consuming and labor-intensive. Currently, specialized radish harvesting equipment is commonly used. For example, patent publication number CN220571013U discloses a radish harvesting device, including a pole and a harvesting mechanism mounted on the pole. This mechanism includes a harvesting component, a pulling component, and a resetting component. The harvesting component includes a limiting rod, the outer surface of which is movably sleeved with the inner wall of the pole. A clamp is fixedly sleeved on the outer surface of the limiting rod, and a convex rod is fixedly installed on the side of the clamp. A hinge block is movably sleeved on the outer surface of the convex rod, and a connecting rod is hinged to the other end of the hinge block. The pulling component drives the two clamps to rotate via the connecting rod.

[0003] When using the aforementioned radish-harvesting device, the clamps are first placed close to the left and right sides of the radish leaves. Then, the pull rod is manually pulled upwards, causing the sleeve to drive the bottom block along the inner wall of the opening and compress the rigid spring. This causes the connecting rod to drive the two clamps to rotate around the limit rod as the axis to clamp the radish leaves. Then, the entire radish is pulled out of the ground by pulling the rod. In summary, harvesting radishes requires manually pulling the pull rod, which is very strenuous. Moreover, if the soil is hard, the radish leaves are easily broken during the harvesting process, and the radish is difficult to pull out. Therefore, an automatic radish harvesting device that facilitates radish harvesting is now being developed. Summary of the Invention

[0004] This invention provides an automatic radish harvesting device that facilitates radish pulling, overcoming the drawback of existing radish pulling devices that require considerable effort to pull radishes.

[0005] The technical solution of this invention is: an automatic radish harvesting device, comprising a harvesting cart and a first support frame. The harvesting cart is rotatably connected to the first support frame, which is symmetrically arranged along the longitudinal direction of the harvesting cart. A lifting component is provided inside the first support frame. An electric push rod, symmetrically arranged along the longitudinal direction of the harvesting cart, is rotatably connected to the harvesting cart. The telescopic rod of the electric push rod is rotatably connected to the first support frame. A picking component, symmetrically arranged along the longitudinal direction of the harvesting cart, is located on the side of the harvesting cart away from the first support frame. A cutting component is located on the side of the harvesting cart near the picking component. A storage component is located on the side of the harvesting cart near the picking component. The cleaning components include a second support frame symmetrically arranged along the longitudinal direction of the harvesting vehicle on one side. The second support frame is connected to a first telescopic component symmetrically arranged. Several mounting brackets are slidably connected to the second support frame. The mounting brackets are connected to the first telescopic components. A guide plate is slidably connected to the side of the mounting bracket away from the support frame. A spring is connected between the top of the guide plate and the mounting bracket. A rotating spray disc is rotatably connected to the guide plate. Several tie rods are connected to the rotating spray disc along the circumference. The harvesting vehicle is connected to a liquid storage tank. The liquid storage tank is equipped with several water pumps. The water pumps are connected to guide pipes, which are rotatably connected to and connected to the rotating spray disc.

[0006] In one embodiment, the lengths of the first and third mounting brackets are shorter than the lengths of the second and fourth mounting brackets.

[0007] In one embodiment, the guide plate is inclined on the side away from the mounting bracket.

[0008] In one embodiment, the nozzles of the first and third rotating spray discs face rearward, while the nozzles of the second and fourth rotating spray discs face forward.

[0009] In one embodiment, a connecting plate is also included. The connecting plate is connected to the side of the harvesting vehicle near the first support frame. The connecting plate is slidably connected to symmetrically arranged guide frames. The guide frames have an inclined surface on the side away from the connecting plate. The guide frames are connected to contact members on the side away from each other. The first support frame has an L-shaped plate on the side near the contact member. The L-shaped plate and the contact member are pressed together.

[0010] In one embodiment, the system further includes an electric slide rail symmetrically arranged along the longitudinal direction of the guide frame. The electric slide rail is mounted on the guide frame, and a movable block is slidably connected to the electric slide rail. A rotating rod is rotatably connected to the movable block, and a limit ring is connected to the rotating rod. Two adjacent limit rings form a semicircle, and multiple limit ropes are connected between the limit ring and the guide frame.

[0011] In one embodiment, a distance sensor is also included, which is mounted on the guide frame and electrically connected to the electric slide rail via a control module.

[0012] In one embodiment, a motor is also included, which is mounted on a first support frame. The motor and a distance sensor are electrically connected via a control module. The output shaft of the motor is connected to a connecting rod, and the connecting rod is connected to a pressure plate. The first support frame is provided with a blocking component for blocking the radish greens on the side near the motor.

[0013] In one embodiment, the blocking component includes a second telescopic component. The second telescopic component, which is symmetrically arranged along the longitudinal direction of the first support frame, is connected to the first support frame. The side of the second telescopic component away from the first support frame is connected to a blocking frame. A rotating block is rotatably connected to the blocking frame, and the rotating block and the pressure plate are pressed together.

[0014] In one embodiment, a cutting tool is also included. The cutting tool is disposed on the top of the first support frame, and a limiting plate is connected to the top of the cutting tool. A wedge-shaped surface is provided on the side of the limiting plate near the cutting tool, and a baffle is connected to the top of the cutting tool.

[0015] The beneficial effects are: the present invention can adjust the height of the radish-pulling component by using an electric push rod according to different regions, different planting modes and radish varieties, which makes it easier to pull out the radish.

[0016] Before pulling out the radish using the lifting assembly, the present invention wets the soil by spraying water with a rotating spray disc and loosens the soil by rotating a tie rod, which allows the radish to be pulled out more quickly.

[0017] This invention uses a guide frame to lift the radish leaves that are growing outwards, so that the lifting component can contact the outward-growing radish leaves and lift the radish more effectively.

[0018] When the distance sensor detects the radish, the radish tops are located between two limiting rings. The limiting rings can concentrate the radish tops and prevent them from scattering. The electric slide rail drives the moving block seat to move to the left. Under the action of the limiting rope, the limiting rings will rotate and push the radish tops to the left, which makes it easier to pull the radish. Attached Figure Description

Detailed Implementation

[0035] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0036] Example 1: An automatic radish harvesting device, such as Figures 1-7As shown, the system includes a harvesting vehicle 1, a pulling assembly 11, a first support frame 1101, a picking assembly 12, a cleaning assembly 13, a cutting assembly 14, a storage assembly 15, a rotating spray disc 16, a tie rod 17, a guide pipe 18, a mounting bracket 19, a guide plate 110, a spring 111, a second support frame 112, a first telescopic assembly 113, a liquid storage tank 114, and a water pump 115. The first support frame 1101 is rotatably connected to both the front and rear sides of the upper right part of the harvesting vehicle 1. Each first support frame 1101 contains a pulling assembly 11 for pulling out the radishes. Electric push rods are rotatably connected to both the front and rear sides of the upper right part of the harvesting vehicle 1. The right side of the telescopic rod of the electric push rod is rotatably connected to the first support frame 1101. The system can be customized according to different regions and planting methods. Depending on the radish variety, the planting height of the radishes will vary. The height at which the pulling component 11 pulls the radishes can be controlled. For example, if some radishes are planted higher, the extension rod of the electric pusher needs to be extended, causing the first support frame 1101 to rotate counterclockwise. The first support frame 1101 then causes the pulling component 11 to rotate counterclockwise for adjustment, and the pulling height on the right side of the pulling component 11 is adjusted upwards. If some radishes are planted lower, the extension rod of the electric pusher can be shortened, causing the first support frame 1101 and the pulling component 11 to rotate clockwise. The pulling height on the right side of the pulling component 11 is adjusted downwards. This ensures that the equipment does not damage or miss any radishes during harvesting. (Harvesting vehicle 1 left...) The upper part of the harvesting vehicle 1 has two front and rear sides equipped with retrieval components 12 for picking up radishes. The top center of the harvesting vehicle 1 has two front and rear sides equipped with cutting components 14 for removing radish tops. The left side of the harvesting vehicle 1 has a storage component 15 for storing radishes. The left side of the harvesting vehicle 1 has two front and rear sides equipped with cleaning components 13 for cleaning radishes. The right side of the harvesting vehicle 1 has two front and rear sides welded with second support frames 112. The upper and lower sides of the right side of the second support frame 112 are connected with first telescopic components 113. The front and rear sides of the second support frame 112 are slidably connected with mounting frames 19. The first telescopic components 113 are connected to adjacent mounting frames 19. A total of four mounting frames 19 are provided, wherein the first and third mounting frames 19 from front to back are shorter than the second and third. Four mounting brackets 19 are slidably connected to the lower right side of each mounting bracket 19. The right side of the guide plate 110 has an inclined structure. When the inclined structure of the guide plate 110 approaches the radish, the guide plate 110 moves away from the radish due to the action of the inclined structure. The guide plate 110 then moves the mounting bracket 19 along with it, and the first telescopic component 113 extends. This allows the guide plate 110 to adjust its position according to the size of the radish, preventing the guide plate 110 from puncturing the radish. After the radish is removed, the first telescopic component 113 will cause the mounting bracket 19 and the guide plate 110 to return to their original positions. A spring 111 is connected between the top of the guide plate 110 and the mounting bracket 19. The spring 111...The guide plate 110 is designed to absorb shock. Rotary spray discs 16 are rotatably connected to the guide plate 110 for wetting the soil. The first and third spray discs 16, from front to back, have their nozzles facing rearward, while the second and fourth spray discs 16 face forward. The two spray discs 16 with their nozzles facing rearward are located to the left of the two spray discs 16 with their nozzles facing forward. After the two spray discs 16 with their nozzles facing forward spray water onto the soil, the two spray discs 16 with their nozzles facing rearward continue spraying water onto the soil for a second wetting, making the soil looser and easier to pull out the radishes. Four equally spaced tie rods 17 are connected to the rotating spray discs 16 along their circumference. 7 is used for loosening the soil. During the movement of this automatic radish harvesting device, the tie rod 17 will also move. After the tie rod 17 comes into contact with the soil, it will drive the rotating spray disc 16 to rotate. The tie rod 17 will loosen the soil, and the rotating spray disc 16 will spray water out. The right side of the harvesting vehicle 1 is bolted to a water storage tank 114. Before harvesting radishes, water can be injected into the water storage tank 114 for storage. Water pumps 115 are installed on both the front and rear sides of the right side of the water storage tank 114. The right side of each water pump 115 is connected to a guide pipe 18. The right end of the guide pipe 18 is rotatably connected to the middle of the rotating spray disc 16. By turning on the water pump 115, water can be injected into the rotating spray disc 16 through the guide pipe 18, and the rotating spray disc 16 will spray the water out.

[0037] When harvesting radishes using this automatic radish harvesting device, the harvesting vehicle 1 can be driven to the harvesting position. Based on the height of the radish planting, the angles of the first support frame 1101 and the lifting component 11 are adjusted using the electric push rod, so that the right side of the lifting component 11 is also adjusted to the correct height. Then, the lifting component 11, the take-up component 12, the cleaning component 13, the cutting component 14, the storage component 15, and the water pump 115 are activated. The spray disc 16 is rotated to spray water and wet the soil. Simultaneously, the harvesting vehicle 1 is controlled to move to the right. During the rightward movement of the harvesting vehicle 1, the tie rod 17 will push the wetted soil into the soil. After loosening the soil, the radish tops are pulled up into the pulling component 11, which then pulls up the radish. The radish then enters the picking component 12, which picks up the radish and places it onto the cutting component 14 for cutting. The cutting component 14 cuts off the radish tops and pushes them into the cleaning component 13 for cleaning. After cleaning, the cleaning component 13 pushes the radish tops into the storage component 15 for storage. After the radish is harvested, the pulling component 11, picking component 12, cleaning component 13, cutting component 14, storage component 15, water pump 115, and harvesting vehicle 1 can be turned off.

[0038] Example 2: Based on Example 1, such as Figure 8As shown, it also includes a guide frame 2, a contact element 21, a connecting plate 22, and an L-shaped plate 23. A connecting plate 22 is welded to the middle of the upper right part of the harvesting vehicle 1. The guide frame 2 is slidably connected to both the front and rear sides of the right side of the connecting plate 22. The right side of the guide frame 2 is provided with an inclined surface. The contact element 21 is welded to the side of the guide frame 2 that is far apart from each other. An L-shaped plate 23 is welded to the upper right part of the first support frame 1101. The L-shaped plate 23 and the contact element 21 are pressed together.

[0039] During the growth of radishes, the radish greens will grow more and more abundant, and may spread out in all directions. When the pulling component 11 approaches the radish greens, it may not be able to reach the spread greens because of their spread growth, and can only pull out the vertically growing greens. If there are few vertically growing greens, the pulling component 11 may break the greens before the radish is pulled out. Therefore, a guide frame 2 is set up. When the guide frame 2 approaches the radish greens, due to the inclined surface on the right side of the guide frame 2, the guide frame 2 can lift the spread greens so that the pulling component 11 can reach the spread greens and pull out the radish. When the pulling component 11 rotates to adjust the pulling height, the pulling component 11 will drive the L-shaped plate 23 to move up and down, and the L-shaped plate 23 will drive the guide frame 2 to adjust up and down. In this way, the guide frame 2 can be adjusted with the pulling height.

[0040] like Figures 9-10 As shown, it also includes a limit ring 3, an electric slide rail 31, a limit rope 32, a moving block 33, a second torsion spring, and a rotating rod 35. Electric slide rails 31 are provided on both the front and rear sides of the upper part of the guide frame 2. Moving blocks 33 are slidably connected to the electric slide rails 31. Rotating rods 35 are rotatably connected to the upper left part of the moving blocks 33. Limit rings 3 are connected to the rotating rods 35. Two adjacent limit rings 3 form a semi-circle. Limit ropes 32 are connected between the right part of the limit ring 3 and the lower left part of the guide frame 2. Limit ropes 32 are also connected between the left part of the limit ring 3 and the right part of the guide frame 2.

[0041] like Figure 10 As shown, it also includes a distance sensor 34, which is mounted on the guide frame 2. The distance sensor 34 and the electric slide rail 31 are electrically connected through the control module. Since the upper part of the radish will protrude from the soil, the electric slide rail 31 will be triggered to work when the distance sensor 34 approaches the radish.

[0042] To ensure the radish greens are more concentrated and prevent them from scattering, allowing them to be moved into the pulling assembly 11 for easier radish removal, a limiting ring 3 is installed. When the guide frame 2 moves to the right, it causes the distance sensor 34, electric slide rail 31, moving block 33, and limiting ring 3 to move to the right as well. When the guide frame 2 guides the radish greens close to the limiting ring 3, the limiting ring 3 gathers the scattered greens together. At this point, the distance sensor 34 detects that the distance to the radish is less than a specified value, and thus controls the electric slide rail 31. The electric slide rail 31 first moves the moving block 33 to the left for 2 seconds, then automatically moves it to the right to reset. When the moving block 33 moves to the left, it will cause the rotating rod 35 and the limiting ring 3 to move to the left. The limiting rope 32 connected to the right side of the guide frame 2 will pull the left side of the limiting ring 3, causing the limiting ring 3 to rotate. The two adjacent limiting rings 3, which were originally closed on the left, are now open on the left and closed on the right under the pulling action of the limiting rope 32 on the right side of the guide frame 2. When the limiting ring 3 moves to the left, the radish top can be pushed to the left to the lifting component 11. When the moving block 33 moves to the right, it will cause the rotating rod 35 and the limiting ring 3 to move to the right. Under the pulling action of the limiting rope 32 connected to the left side of the guide frame 2, the limiting ring 3 rotates and resets.

[0043] like Figures 11-13 As shown, it also includes a pressure plate 4, a motor 41, a connecting rod 45, and a blocking assembly. The right side of the first support frame 1101 is connected to the motor 41 by bolts. The motor 41 and the distance sensor 34 are electrically connected through a control module. The output shaft of the motor 41 is connected to the connecting rod 45. The left side of the connecting rod 45 is connected to the pressure plate 4. The pressure plate 4 is used to press the radish tops to the left. The lower right side of the first support frame 1101 is provided with a blocking assembly for blocking the radish tops. The blocking assembly includes a second telescopic assembly 42, a blocking frame 43, and a rotating block 44. The front and rear sides of the lower right side of the first support frame 1101 are connected to the second telescopic assembly 42. The right side of the second telescopic assembly 42 is fixedly connected to the blocking frame 43. The rotating block 44 is rotatably connected to the blocking frame 43. The rotating block 44 and the pressure plate 4 are pressed together.

[0044] When the radish tops approach the lifting component 11, some radish tops may not have fully entered the lifting component 11. Therefore, a component is provided to press the radish tops firmly and push them into the lifting component 11. When the distance sensor 34 detects that the distance between the radish and the lifting component is less than the rated value, the distance sensor 34 simultaneously triggers the electric slide rail 31 and the motor 41 to work. The electric slide rail 31 drives the moving block 33 to move to the left, which in turn causes the limiting ring 3 to push the radish tops to the left and closer to the rotating block 44. At the same time, the output shaft of the motor 41 first rotates 300 degrees clockwise and then rotates counterclockwise to the right to reset. The 300-degree clockwise rotation of the output shaft of the motor 41 drives the connecting rod 45 and the pressure plate 4 to rotate clockwise. As the clock hands rotate, when the pressure plate 4 contacts the radish tops, it presses the radish tops to the left. When the pressure plate 4 contacts the rotating block 44, it squeezes the rotating block 44, causing the rotating block 44 to rotate. At this time, the radish tops are located between the pressure plate 4 and the rotating block 44. The rotation of the rotating block 44 will press the radish tops tightly. Then the pressure plate 4 continues to push the radish tops to the left, and can also push the rotating block 44 and the abutment 43 to the left. The second telescopic component 42 is compressed. When the radish tops are pushed into the pull-out component 11, the pull-out component 11 pulls out the radish tops. Afterwards, after the connecting rod 45 and the pressure plate 4 rotate counterclockwise to reset, the second telescopic component 42 extends, causing the abutment 43 and the rotating block 44 to move and reset.

[0045] like Figures 14-15 As shown, it also includes a limiting plate 5, a cutting tool 51 and a baffle 52. The top of the first support frame 1101 is provided with a cutting tool 51, the top of the cutting tool 51 is connected to the limiting plate 5, the bottom of the limiting plate 5 is provided with a wedge-shaped surface, and the left side of the top of the cutting tool 51 is connected to the baffle 52.

[0046] When the radish tops are transported to the left by the removal component, after the upper part of the radish tops comes into contact with the bottom of the limiting plate 5, the wedge-shaped surface of the limiting plate 5 will guide the radish tops to bend along the side of the limiting plate 5 that is far away from each other. The cutter 51 will then cut off the upper part of the radish tops. The baffle 52 can block the upper part of the radish tops, thus shortening the radish tops, making it easier for the subsequent cutting component 14 to cut the radish tops.

All equivalent substitutions made within the principles of the present invention should be included within the scope of protection of the present invention. Contents not described in detail in this invention are existing technologies known to those skilled in the art.
