Description

Technical Field

[0001] This invention relates to a crop harvesting device, specifically a radish cutting platform and a radish harvester. Background Technology

[0002] Currently, radish and carrot harvesting is mainly done manually. Although some radish harvesting equipment on the market can automate the harvesting process, existing equipment lacks flexibility and adaptability. Due to differences in radish varieties and growing environments, radishes vary in height, size, and depth. For example, white radishes and carrots differ significantly in size, growth depth, and height. Furthermore, the row spacing for radishes varies across different plots. Existing radish harvesting equipment cannot flexibly adapt to harvesting different types of radishes (including various types of radishes and carrots) and different row spacings. This necessitates the use of different harvesting equipment for different varieties and plots, resulting in higher harvesting costs.

[0003] Therefore, there is an urgent need for a radish harvesting device that can be flexibly adjusted to be suitable for harvesting different types of radishes with different row spacings. Summary of the Invention

[0004] The purpose of this invention is to provide a radish cutting platform and a radish harvester to solve the problem that existing radish harvesting equipment cannot adapt to harvesting different types of radishes with different row spacings.

The first adjustment device, each of the clamping devices is connected to the crossbeam through a first adjustment device, and the first adjustment device and the crossbeam are adjustable, used to adjust the height of the clamping and conveying mechanism and its left and right position on the crossbeam; A loosening shovel, located below the front end of the clamping device, is used to shovel into the soil to loosen the radish. A depth-limiting wheel is mounted on the cutting platform, located at the front end of the clamping device and staggered from the clamping device in the left-right direction, for contacting the ground at the furrow. A cutting blade, located at the rear of the clamping device, is used to cut the stems and leaves of the radish; and A conveying device, mounted on the cutting frame and located below the rear of the clamping device, is used to receive and output radishes after the stems and leaves have been removed.

[0006] Furthermore, the spacing adjustment mechanism includes a connecting part, a horizontal telescopic rod, and a horizontal adjusting rod. Connecting parts are respectively provided on the left and right clamping and conveying mechanisms, and the two connecting parts are connected to each other through the horizontal telescopic rod and the horizontal adjusting rod.

[0007] Furthermore, the first adjustment device includes a front adjustment mechanism and a rear adjustment mechanism.

[0008] The front adjustment mechanism is located at the front of the clamping device and includes a first connecting seat. The first connecting seat is adjustablely connected to the crossbeam at the front of the cutting table frame. A telescopic cylinder is hinged to the first connecting seat, and a bushing is provided at the end of the telescopic cylinder to connect with the horizontal shaft on the clamping device. The rear adjustment mechanism is located at the rear end of the clamping device and includes a second connecting seat. The second connecting seat is adjustablely connected to the crossbeam at the rear of the cutting table frame. A first vertical adjustment rod is provided on the second connecting seat, and a bushing is provided at the end of the first vertical adjustment rod to connect with the horizontal shaft on the clamping device.

[0009] Furthermore, the depth-limiting wheel is connected to the cutting table frame via a second adjustment device. The second adjustment device includes a connecting frame and a wheel frame.

One end of the wheel frame is hinged to the connecting frame, and the other end is hinged to a second vertical adjustment rod. The second vertical adjustment rod is connected to the connecting frame, and the depth-limiting wheel is mounted on the wheel frame.

[0010] Furthermore, it also includes a third adjustment device, which includes a third connecting seat. The third connecting seat is adjustablely connected to the crossbeam at the lower rear end of the cutting table frame. The loosening shovel is located at the front end of the mounting rod. The rear end of the mounting rod is hinged to the third connecting seat. A third vertical adjustment rod is hinged to the middle of the mounting rod.

A third adjustment mechanism allows for adjustment of the height of the loosening shovel, thus accommodating radishes at different growth depths.

[0019] This invention is highly flexible and can be applied to the harvesting of radishes of different varieties, with different growth conditions and different row spacing. Attached Figure Description

[0026] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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. Example

[0027] like Figures 1 to 4 As shown, this embodiment is a radish cutting platform, which specifically includes a cutting platform frame 1, a clamping device, a first adjusting device, a loosening shovel 9, a depth limiting wheel 7, a cutting blade 12, and a conveying device.

[0028] The radish cutting platform frame 1 is specifically a frame structure, with triangular frames on both sides. One side plate of the triangular frame is located at the top and is approximately horizontal. The two triangular frames are connected by multiple horizontally arranged and parallel crossbeams 1-1. A crossbeam 1-1 is located at each vertex of the triangular frame. The crossbeam 1-1 is specifically a square tube.

[0029] At least one clamping device is installed on the cutting platform 1. In one specific embodiment, there are three clamping devices, which are installed side by side on the cutting platform 1, so that three rows of radishes can be harvested at the same time.

[0030] Each clamping device specifically includes two symmetrically arranged clamping and conveying mechanisms 2 on the left and right, and a spacing adjustment mechanism 3 for connecting the two clamping and conveying mechanisms 2. There are at least two spacing adjustment mechanisms 3, and multiple spacing adjustment mechanisms 3 are distributed along the length direction of the clamping device. The spacing between the two clamping and conveying mechanisms 2 can be adjusted through the spacing adjustment mechanism 3.

[0031] Each clamping and conveying mechanism 2 includes a long strip-shaped mounting plate 2-1. A drive wheel 2-2 is mounted at one end of the mounting plate 2-1, and a driven wheel 2-3 is mounted at the other end. A belt 2-4 is mounted on the drive wheel 2-2 and the driven wheel 2-3. The drive wheel 2-2 can be driven to rotate by a drive element such as a motor, thereby driving the belt 2-4 to move. Several tensioning wheels are arranged along the length of the mounting plate 2-1 to tension the belt 2-4.

[0032] The clamping device is tilted backward and upward as a whole. The belts 2-4 of the two clamping and conveying mechanisms 2 on the left and right work together to clamp the stems and leaves of the radish, thereby pulling the radish upward and conveying it backward at the same time.

[0033] To facilitate the clamping of the radish stems and leaves, a closing device 6 is provided at the front end of each clamping device. The closing device 6 is specifically two inclined rod-shaped structures, which are respectively installed at the front ends of the left and right clamping mechanism mounting plates 2-1. During operation, the front end of the closing device 6 extends under the radish stems and leaves, and the closing device 6 gradually moves forward, gradually gathering the stems and leaves together from bottom to top and then sending them into the clamping device.

[0034] To facilitate pulling the radish upwards, a soil loosening shovel 9 is provided below the front end of each clamping device. The soil loosening shovel 9 is inserted into the soil to loosen the radish, so that the clamping device can smoothly pull the radish upwards.

[0035] A depth-limiting wheel 7 is installed in front of the header frame 1. The depth-limiting wheel 7 is located at the front end of the clamping device and is staggered from the clamping device in the left-right direction. The clamping device corresponds to the furrow, and the depth-limiting wheel 7 is used to contact the ground at the furrow to support the entire header. Generally, two depth-limiting wheels 7 are provided, and the two depth-limiting wheels 7 can stably support the header.

[0036] A conveying device is installed on the cutting frame 1. The conveying device is located below the rear of the clamping device. A cutter 12 is set below the rear of each clamping device. When the clamping device pulls the radish upward and conveys it backward through the cutter 12, the cutter 12 cuts off the excess stems and leaves on the upper part of the radish. After the stems and leaves are separated, the radish falls onto the conveying device below. The stems and leaves held by the clamping device continue to move backward with the clamping device, realizing the separation of the radish from the stems and leaves. The conveying device directionally conveys the radish for subsequent collection.

[0037] The spacing adjustment mechanism 3 specifically includes a connecting part 3-1, a horizontal telescopic rod 3-3, and a horizontal adjusting rod 3-2. Connecting parts 3-1 are respectively provided on the mounting plates 2-1 of the left and right clamping conveying mechanisms 2. Each connecting part 3-1 is a rod-shaped structure extending upwards perpendicular to the mounting plate 2-1. A horizontal telescopic rod 3-3 connects the two connecting parts 3-1. An angle bracket is provided at the top of each connecting part 3-1. A horizontal adjusting rod 3-2 is provided between the two angle brackets. The horizontal adjusting rod 3-2 is a screw, with both ends passing through the angle brackets at both ends. Nuts are provided on both sides of the angle brackets. The nuts allow adjustment of the spacing between the two connecting parts 3-1 and corresponding extension and retraction of the horizontal telescopic rod 3-3, thereby adjusting the spacing between the left and right clamping conveying mechanisms 2.

[0038] To facilitate adjustment of the left-right and up-down positions of the clamping devices, a first adjustment device is provided on the crossbeam 1-1 of the cutting table frame 1. Each clamping device is connected to the crossbeam 1-1 through a first adjustment device, and the first adjustment device and the crossbeam 1-1 are adjustable.

[0039] The first adjustment device specifically includes a front adjustment mechanism 4 and a rear adjustment mechanism 5, which together realize the connection between the clamping device and the cutting table frame 1 and the adjustment of the clamping device.

[0040] The front adjustment mechanism 4 is located at the front of the clamping device and includes a first connecting seat 4-1. The first connecting seat 4-1 includes two rectangular plates, which are located on the upper and lower sides of the crossbeam 1-1, respectively. An upwardly extending column is fixedly connected to the upper rectangular plate. The two rectangular plates are connected to each other by two sets of bolts. Loosening the bolts allows adjustment of the position of the first connecting seat 4-1 on the crossbeam 1-1, and tightening the bolts fixes the first connecting seat 4-1 to the crossbeam 1-1, thus achieving an adjustable connection between the first connecting seat 4-1 and the crossbeam 1-1 at the front of the cutting table frame 1. A telescopic cylinder 4-2 is hinged to the upper end of the column and extends downward. A bushing is fixedly connected to the lower end of the telescopic cylinder 4-2 and is sleeved on a horizontal shaft on the clamping device. This horizontal shaft can be fixedly connected to the mounting plate 2-1 of one of the clamping and conveying mechanisms 2. In a specific embodiment, the horizontal shaft is specifically the horizontal telescopic rod 3-3 of the spacing adjustment mechanism 3. Each clamping device has a front adjustment mechanism 4 at its front end.

[0041] The rear adjustment mechanism 5 is located at the rear end of the clamping device and includes a second connecting seat 5-1. The second connecting seat 5-1 includes two rectangular plates, which are located on the upper and lower sides of the crossbeam 1-1, respectively. A downwardly extending column is fixedly connected to the lower rectangular plate. The two rectangular plates are connected to each other by two sets of bolts. Loosening the bolts allows adjustment of the position of the second connecting seat 5-1 on the crossbeam 1-1, and tightening the bolts fixes the second connecting seat 5-1 to the crossbeam 1-1, thus achieving an adjustable connection between the second connecting seat 5-1 and the crossbeam 1-1 at the rear of the cutting table frame 1. A downward-pointing first vertical adjustment rod 5-2 is installed on the first column. A bushing is fixedly connected to the lower end of the first vertical adjustment rod 5-2, and the bushing is connected to a horizontal shaft on the clamping device. The horizontal shaft can be the horizontal telescopic rod 3-3 of the spacing adjustment mechanism 3 at the rear of the clamping device. In a specific embodiment, horizontal shafts are respectively connected to the rear ends of the mounting plates 2-1 of the left and right clamping mechanisms. The two horizontal shafts are respectively connected to a first vertical adjustment rod 5-2 through a bushing. Each first vertical adjustment rod 5-2 is connected to a crossbeam 1-1 at the rear of the cutting table frame 1 through a second connecting seat 5-1.

[0042] Specifically, the first vertical adjusting rod 5-2 is a screw rod. The lower end of the screw rod is fixedly connected to the bushing, and the upper end of the screw rod passes through the side plate on one side of the column and is screwed with a nut.

[0043] When it is necessary to adjust the left and right positions of the clamping device, simply adjust the positions of the first connecting seat 4-1 and the second connecting seat 5-1 on the crossbeam 1-1 simultaneously. After adjusting the positions, fix the first connecting seat 4-1 and the second connecting seat 5-1 to the crossbeam 1-1. When it is necessary to adjust the vertical height of the clamping device, adjust the length of the telescopic cylinder 4-2 and the length of the first vertical adjusting rod 5-2 to adjust the overall height and tilt angle of the clamping device.

[0044] To adjust the depth-limiting wheel 7, it is connected to the cutting table frame 1 via a second adjusting device 8. The second adjusting device 8 includes a connecting frame 8-1 and a wheel frame 8-2. The connecting frame 8-1 includes a forward-extending horizontal rod, a vertical rod below the horizontal rod, and a diagonal brace. The horizontal rod is connected to at least two crossbeams 1-1. A connecting lug is provided on the horizontal rod, and a corresponding rectangular plate is provided above the crossbeams 1-1. The rectangular plate is bolted to the connecting lug. Loosening the bolts allows adjustment of the left and right position of the connecting frame 8-1 on the crossbeams 1-1, while tightening the bolts fixes the connecting frame 8-1 to the crossbeams 1-1, thus achieving an adjustable connection between the connecting frame 8-1 and the crossbeams 1-1. One end of the wheel frame 8-2 is hinged to the vertical rod of the connecting frame 8-1, and the other end is hinged to a second vertical adjusting rod 8-3. The second vertical adjusting rod 8-3 is connected to the front end of the horizontal rod of the connecting frame 8-1, and the depth-limiting wheel 7 is mounted on the wheel frame 8-2. The height of the depth limiting wheel 7 can be adjusted using the second vertical adjusting rod 8-3.

[0045] The second vertical adjusting rod 8-3 is specifically a screw rod. A square tube is fixedly sleeved at the lower end of the screw rod, and a hinge seat is connected to the lower end of the square tube. The upper end of the screw rod passes through the horizontal rod of the connecting frame 8-1 and is screwed with a nut. The length of the second vertical adjusting rod 8-3 is adjusted by turning the nut.

[0046] To facilitate the adjustment of the loosening shovel 9, a third adjustment device 10 is also provided. The third adjustment device 10 includes a third connecting seat 10-2, which comprises two rectangular plates located on the front and rear sides of the crossbeam 1-1, respectively. An installation rod 10-1 is hinged to the front rectangular plate. The two rectangular plates are connected to each other by two sets of bolts. Loosening the bolts allows adjustment of the position of the third connecting seat 10-2 on the crossbeam 1-1, while tightening the bolts fixes the third connecting seat 10-2 to the crossbeam 1-1, thus achieving an adjustable connection between the third connecting seat 10-2 and the crossbeam 1-1 located below the rear of the cutter frame 1. The loosening shovel 9 is installed at the front end of the installation rod 10-1. A third vertical adjustment rod 10-3 is hinged to the middle of the installation rod 10-1. The upper end of the third vertical adjustment rod 10-3 is provided with a bushing connected to a horizontal shaft on the clamping device. The third vertical adjusting rod 10-3 is specifically an adjusting pull rod. Sleeves are fixedly connected to both ends of the adjusting pull rod. The lower sleeve is connected to the horizontal shaft on the mounting rod 10-1, and the upper sleeve is connected to the horizontal shaft on the clamping device. This horizontal shaft can be a horizontal shaft set on the connecting plate, or it can be the horizontal telescopic rod 3-3 of the spacing adjusting mechanism 3.

[0047] The third vertical adjustment rod 10-3 allows the loosening shovel 9 to swing up and down around the third connecting seat 10-2, thereby adjusting the height of the loosening shovel 9.

[0048] A sleeve is connected to a mounting plate 2-1 in the clamping device. A vertical connecting rod is inserted through the sleeve. A soil remover 11 is installed on the connecting rod. The height of the soil remover 11 can be adjusted by the connecting rod. The soil remover 11 includes a rotating shaft and flexible rods evenly distributed along the rotating shaft. The rotating shaft is driven to rotate by a drive mechanism such as a motor. When the radish passes through the soil remover 11, the soil remover 11 removes the soil from the radish.

[0049] The conveying device includes two first transverse conveyors 13 and an elevator 14 located between the two first transverse conveyors 13. The front end of the elevator 14 is located below the two first transverse conveyors 13. Both first transverse conveyors 13 move inward to convey the radish inward to the elevator 14, and then convey it backward through the elevator 14.

[0050] A second transverse conveyor 15 is provided below the end of the clamping device. The clamping device outputs the stems and leaves of the radish from the end. The output stems and leaves fall onto the second transverse conveyor 15. The second transverse conveyor 15 outputs the stems and leaves to one side or both sides. The output stems and leaves fall into the storage container or directly onto the ground. Example

[0051] like Figure 5 As shown, this embodiment is a radish harvester, including a vehicle body 16, with a radish cutting platform as described in Embodiment 1 located at the front of the vehicle body 16. A rear lifting device 18 and a hopper 19 are also provided on the vehicle body 16. The radishes harvested by the radish cutting platform are transported to the rear lifting device 18 via the lifting device 14, and then transported to the hopper 19 via the rear lifting device 18.

[0052] The frame of the radish cutter's lifting device 14 is connected to the cutting platform frame 1 as an integral structure. The rear end pivot of the lifting device 14 is hinged to the vehicle body 16. An adjusting cylinder 17 is also provided between the cutting platform frame 1 and the vehicle body 16. The overall up and down adjustment of the cutting platform frame 1 is achieved by extending and retracting the adjusting cylinder 17.

[0053] Furthermore, a limit triggering device 20 is provided below the front end of the clamping device. The limit triggering device 20 includes a limit plate 20-1 that is shaft-connected to the clamping device. The limit plate 20-1 is in contact with the ground. When the ground level rises, the limit plate 20-1 swings upward to trigger the limit switch 20-2. The limit switch controls the adjusting cylinder 17 to extend and retract to adjust the height of the cutting table frame 1, thereby adapting the cutting table frame 1 to the undulating ground.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
