Description

Technical Field

[0001] This invention relates to the field of crop harvesting technology, specifically a harvester for root and tuber crops. Background Technology

[0002] Root vegetables such as carrots, onions, garlic, peanuts, potatoes, and sweet potatoes grow in the soil. Traditional harvesting methods mostly rely on manual labor to dig them out of the soil or pull them out by hand and spread them in the field. Then, manual labor is used to pick them up, remove the tassels and leaves from the stems, and clear away the soil before harvesting. Traditional agriculture mainly relies on manual digging and pulling to harvest root vegetables, which is very labor-intensive for farmers. Summary of the Invention

[0003] The purpose of this invention is to provide a harvester for root and tuber crops to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A harvester for root and tuber crops includes a trolley frame with a control panel mounted on it. Two sets of driven wheels are rotatably mounted on the trolley frame. Two sets of first motors are fixedly mounted on the trolley frame, with the output shafts of the first motors fixedly connected to drive wheels. The harvester also includes:

[0006] A pull-out separation structure connected to a trolley frame includes a sleeve fixedly connected to the trolley frame, an open frame slidably connected to the sleeve, a spring installed between the sleeve and the open frame, a cutting mechanism installed on the open frame, active telescopic frames symmetrically installed on both sides of the sleeve, a slide rail slidably connected to the sleeve fixedly installed at the moving end of the active telescopic frame, a second motor fixedly installed on the slide rail, a third motor fixedly installed on the slide rail, the output shaft extension directions of the second motor and the third motor being staggered and perpendicular, a rotating frame fixedly connected to the output shaft of the second motor, a linkage block hinged to the rotating frame, an electric gripper fixedly connected to the linkage block, a first hinge frame fixedly connected to the output shaft of the third motor, and a second hinge frame hinged to the first hinge frame and hinged to the linkage block.

[0007] A lifting and collecting structure mounted on a trolley frame.

[0008] As a further improvement of the present invention: the cutting mechanism includes a first electric telescopic rod fixedly connected to the opening frame, a push frame fixedly connected to the moving end of the first electric telescopic rod, inclined grooves symmetrically opened on the push frame, a sliding arm slidably connected to the opening frame in the inclined groove, and a blade fixedly connected to the sliding arm.

[0009] As a further improvement of the present invention: a camera that is communicatively connected to the control panel is fixedly installed on the slide.

[0010] As a further improvement of the present invention: the lifting and collecting structure includes a recycling bin fixedly connected to a trolley frame, a dual-output shaft motor fixedly connected to the trolley frame, a winding reel fixedly connected to the output shaft of the dual-output shaft motor, a pull line fixedly connected to the winding reel, a lifting bucket slidably connected to the pull line, and a displacement conveying mechanism installed on the trolley frame.

[0011] As a further improvement of the present invention: the displacement conveying mechanism includes a second electric telescopic rod fixedly connected to the trolley frame, the moving end of the second electric telescopic rod is fixedly installed with a bracket slidably connected to the trolley frame, the bracket is fixedly connected with a roller frame, multiple sets of rollers are rotatably installed on the roller frame, the multiple sets of rollers are connected to a conveyor belt, a fourth motor is fixedly installed on the roller frame, and the output shaft of the fourth motor is fixedly connected to one of the sets of rollers.

[0012] As a further improvement of the present invention: the recycling bin includes an upper box body fixedly connected to the trolley frame, the upper box body has an opening, an elastic element is installed on the upper box body, and a wire mesh box is fixedly connected to the elastic element and slidably connected to the upper box body.

[0013] As a further improvement of the present invention: a guide rail that is slidably connected to the lifting bucket is fixedly installed on the upper box body.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In use, the trolley frame is pushed, and the first motor drives the drive wheel to rotate, thereby moving the invention so that the above-ground part of the crop is close to the electric gripper. The electric gripper clamps the above-ground part of the crop, and the active telescopic frame drives the slide to rise along the sleeve. The slide drives the second and third motors to rise. During this period, the second motor drives the rotating frame to deflect, and the third motor drives the first hinge frame to move. The first hinge frame drives the second hinge frame to move. Under the joint drive of the rotating frame and the second hinge frame, the linkage block deflects, thereby lifting the crop while shaking it, making it easier for the crop roots to be pulled out of the soil. At this time, the roots are lifted and press against the opening frame, causing the spring to be compressed. Then the cutting mechanism cuts the crop, causing the roots to fall and be collected by the lifting and collecting structure. The active extension mechanism pushes the crop held by the electric gripper while the electric gripper loosens its grip. This invention uses a pull-and-separate structure to pull and shake the crop, thereby facilitating the separation of the crop's roots and stems from the soil. The roots and stems are then cut out individually and collected using a lifting and collecting structure. This invention replaces manual labor in pulling the crop, saving manpower. Compared to soil-turning root and stem crop harvesters, it is more convenient for harvesting individual crops. Attached Figure Description

[0024] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0025] Example 1, see Figures 1 to 7 As shown, a root and tuber crop harvester includes a trolley frame 1, a control panel 2 mounted on the trolley frame 1, two sets of driven wheels 3 rotatably mounted on the trolley frame 1, and two sets of first motors 4 fixedly mounted on the trolley frame 1. The output shafts of the first motors 4 are fixedly connected to drive wheels 5. The harvester also includes:

[0026] A pull-out separation structure 6 connected to the trolley frame 1 includes a sleeve 7 fixedly connected to the trolley frame 1. An opening frame 8 is slidably connected to the sleeve 7. A spring is installed between the sleeve 7 and the opening frame 8. A cutting mechanism 9 is installed on the opening frame 8. Active telescopic frames 10 are symmetrically installed on both sides of the sleeve 7. A slide 11 slidably connected to the sleeve 7 is fixedly installed at the moving end of the active telescopic frame 10. A second motor 12 is fixedly installed on the slide 11. [Further details about the second motor and the third motor are missing from the original text.] The third motor 13 has an output shaft extension direction that is intersecting and perpendicular to the output shaft extension direction of the second motor 12. The output shaft of the second motor 12 is fixedly connected to a rotating frame 14. The rotating frame 14 is hinged to a linkage block 15. An active extension mechanism is installed on the linkage block 15. The linkage block 15 is fixedly connected to an electric gripper 16. The output shaft of the third motor 13 is fixedly connected to a first hinge frame 17. The first hinge frame 17 is hinged to a second hinge frame 18 that is hinged to the linkage block 15.

[0027] Lifting and collecting structure 19 is installed on the trolley frame 1.

[0028] In use, the pusher frame 1 is pushed, and the first motor 4 drives the drive wheel 5 to rotate, thereby moving the invention so that the above-ground part of the crop is close to the electric gripper 16. The electric gripper 16 clamps the above-ground part of the crop. The active telescopic frame 10 drives the slide 11 to rise along the sleeve 7. The slide 11 drives the second motor 12 and the third motor 13 to rise. During this period, the second motor 12 drives the rotating frame 14 to deflect, and the third motor 13 drives the first hinge frame 17 to move. The first hinge frame 17 drives the second hinge frame 18 to move. Under the joint drive of the rotating frame 14 and the second hinge frame 18, the linkage block 15 deflects, thereby lifting the crop while shaking it, so that the roots and stems of the crop can be lifted out of the soil. At this time, the roots and stems are lifted and press the opening frame 8, so that the spring is compressed. Then the cutting mechanism 9 cuts the crop, so that the roots and stems fall and are collected by the lifting and collecting structure 19. The active extension mechanism pushes the crop held by the electric gripper 16 while the electric gripper 16 loosens its grip. This invention uses a pulling and separating structure 6 to pull and shake the crop, thereby facilitating the separation of the crop's roots and stems from the soil. The roots and stems are then cut out separately and collected using a lifting and collecting structure 19. This invention replaces manual labor in pulling the crop, saving manpower. Compared to soil-turning root and stem crop harvesters, it is more convenient for harvesting individual crops.

[0029] In one embodiment, the cutting mechanism 9 includes a first electric telescopic rod 20 fixedly connected to the opening frame 8. A pusher frame 21 is fixedly connected to the moving end of the first electric telescopic rod 20. The pusher frame 21 has symmetrically formed inclined grooves 22. A sliding arm 23, slidably connected to the opening frame 8, is slidably connected to the inclined grooves 22. A blade 24 is fixedly connected to the sliding arm 23. The first electric telescopic rod 20 drives the pusher frame 21 to move, the pusher frame 21 drives the inclined grooves 22 to move, the inclined grooves 22 drive the sliding arm 23 to move, and the sliding arm 23 drives the blade 24 to move, thereby enabling the blade 24 to cut the crop.

[0030] In one embodiment, a camera 25, which is communicatively connected to the control panel 2, is fixedly mounted on the slide 11. The camera 25 is used to photograph crops in the land and transmit the captured images to the control panel 2, thereby facilitating personnel to observe the operation of the electric gripper 16.

[0031] In one embodiment, the lifting and collecting structure 19 includes a collection box 26 fixedly connected to a trolley frame 1. A dual-shaft motor 27 is fixedly connected to the trolley frame 1. A winding reel 28 is fixedly connected to the output shaft of the dual-shaft motor 27. A pull line 29 is fixedly connected to the winding reel 28. The pull line 29 is fixedly connected to a lifting bucket 30 slidably connected to the collection box 26. A displacement conveying mechanism 31 is installed on the trolley frame 1. Falling rhizomes land on the displacement conveying mechanism 31, which conveys the rhizomes to the lifting bucket 30. Driven by the dual-shaft motor 27, the pull line 29 is wound around the winding reel 28, lifting the lifting bucket 30. The rhizomes in the lifting bucket 30 then slide into the collection box 26.

[0032] In one embodiment, the displacement conveying mechanism 31 includes a second electric telescopic rod 32 fixedly connected to the trolley frame 1. A bracket 33, slidably connected to the trolley frame 1, is fixedly mounted on the moving end of the second electric telescopic rod 32. A roller frame 34 is fixedly connected to the bracket 33, and multiple sets of rollers 35 are rotatably mounted on the roller frame 34. These multiple sets of rollers 35 are connected to a conveyor belt. A fourth motor 36 is fixedly mounted on the roller frame 34, and the output shaft of the fourth motor 36 is fixedly connected to one set of rollers 35. The second electric telescopic rod 32 drives the bracket 33 to move, which in turn drives the roller frame 34 to move towards the opening frame 8. The conveyor belt carries the falling rhizomes. Under the drive of the fourth motor 36 on the rollers 35, the conveyor belt transports the rhizomes. During this process, the second electric telescopic rod 32 resets, causing the roller frame 34 to move towards the lifting bucket 30, thereby transporting the rhizomes into the lifting bucket 30.

[0033] In one embodiment, the recycling bin 26 includes an upper box 37 fixedly connected to the trolley frame 1. The upper box 37 has an opening, and an elastic element 38 is installed on it. A net box 39, slidably connected to the upper box 37, is fixedly connected to the elastic element 38. Roots fall into the net box 39 through the opening in the upper box 37. The net box 39 vibrates due to the impact of the falling roots and the support of the elastic element 38, thus facilitating soil detachment from the roots.

[0034] Example 2, based on Example 1, see [link / reference] Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 A guide rail 40 is fixedly installed on the upper housing 37 and slidably connected to the lifting bucket 30. The guide rail 40 is used to guide the movement of the lifting bucket 30.

[0035] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
