Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 and Figure 2This utility model provides a technical solution: a potato harvester, including: a protective plate 1 for mounting a support frame 2, a soil-shoveling mechanism 3 and a screening mechanism 4; a support frame 2 for reinforcement is connected between two sets of the protective plates 1; the support frame 2 can be installed with a tractor; a soil-shoveling mechanism 3 for soil shoveling is provided between the two sets of the protective plates 1 near the support frame 2; a screening mechanism 4 for removing soil is also provided between the two sets of the protective plates 1; a frame 5 is connected to one side of the protective plate 1; a screen cylinder 6 for removing soil is rotatably connected to the inner wall of the frame 5 via pulleys; and a collection mechanism 7 for collecting potatoes is provided on one side of the screen cylinder 6.

[0029] The potato harvester has a support frame 2 that reinforces the two sets of guard plates 1 and is also responsible for connecting to driving vehicles such as tractors. The screen cylinder 6 tumbles the potatoes that enter from the guard plates 1, allowing the potatoes to fall under gravity and removing the soil from the surface of the potatoes. The screen cylinder 6 has a certain inclination, and the end of the screen cylinder 6 near the collecting mechanism 7 is lower than the end near the guard plate 1, so that the potatoes roll into the hollow box 702.

[0030] exist Figure 1 and Figure 3 In the above, the soil-shoveling mechanism 3 includes an axle 31 connected between two sets of guard plates 1 near the support frame 2. The output shaft of the axle 31 is connected to the guard plate 1 through a bearing. The outer side of the output shaft of the axle 31 is rotatably connected to a swing arm 32 for swinging through a bearing and an eccentric wheel. The other end of the swing arm 32 is rotatably connected to a connecting plate 33 for transmission through a rotating shaft. The connecting plate 33 is slidably inserted in the guard plate 1 through a through-hole. The other end of the connecting plate 33 is connected to a shovel 34 for shoveling soil. The shovel 34 is rotatably connected between the two sets of guard plates 1 through a rotating shaft and a bearing.

[0031] In this potato harvester, the outer cylinder of the axle 31 is connected between two sets of guard plates 1, which can reinforce the guard plates 1. The axle 31 is installed with the drive shaft of the tractor or other driving vehicle to drive the output shaft of the axle 31 to rotate. When the axle 31 rotates, it drives the swing arm 32 to swing by the eccentric wheel, thereby causing the shovel 34 to reciprocate to shovel soil.

[0032] exist Figures 1-3 and Figure 5 In the process, the screening mechanism 4 includes a sprocket a401 connected to the output shaft end of the axle 31 for driving the chain a402 to move. The outer side of the sprocket a401 is meshed with a chain a402 for driving sprocket b403 and sprocket c407. The chain a402 is meshed with a sprocket b403 for driving the flower wheel 404 to rotate. The front part of the sprocket b403 is connected to the flower wheel 404 for driving the steel bar 405 to move. The flower wheel 404 is connected through bearings in the two sets of guard plates 1.

[0033] When the output shaft of the axle 31 of this potato harvester rotates, it drives the sprocket a401 to rotate. The sprocket a401 drives the chain a402 to move, which in turn drives the sprocket b403 and the flower wheel 404 to rotate.

[0034] exist Figure 3 In the process, the outer side of the flower wheel 404 is engaged with a steel bar 405 for screening potatoes, and both ends of the steel bar 405 are connected to a belt 406 for connecting multiple sets of steel bars 405. The belt 406 is made of rubber.

[0035] In this potato harvester, two sets of belts 406 are connected together to form a conveyor belt, which is driven by a flower wheel 404. The soil scooped up by the shovel 34 is transported to multiple sets of steel bars 405. The potatoes remain on the steel bars 405, while the soil passes through the gaps between the steel bars 405 and returns to the land.

[0036] exist Figure 5 In the middle, a sprocket c407 for driving the roller 408 to rotate is also meshed on the chain a402, which is far away from the sprocket a401 and sprocket b403. The sprocket c407 is connected through the bearing to the two sets of guard plates 1, and the outer side of the sprocket c407 is rotatably connected to the roller 408 for making the steel bar 405 vibrate up and down through the bracket.

[0037] In this potato harvester, the chain a402 drives the sprocket c407 to rotate when it moves. When the sprocket c407 rotates, it makes the roller 408 come into contact with the steel bar 405 and the belt 406, and then moves away from the steel bar 405 and the belt 406, thereby causing the steel bar 405 and the belt 406 to vibrate and shake the soil off the potatoes.

[0038] exist Figure 5 and Figure 6 In the case, the back of the guard plate 1 is connected to a protective cover 409 for protecting the sprocket a401, chain a402, sprocket b403 and sprocket c407. The inner wall of the protective cover 409 is provided with a tensioning component 410 for pressing the chain a402 onto the sprocket c407. The tensioning component 410 abuts against the chain a402.

[0039] The potato harvester includes a tensioning assembly 410 that abuts against the chain a402. A bracket rotatably connected inside the roller abuts against a protective cover 409. A trapezoidal screw is threaded inside the bracket. One end of the trapezoidal screw is rotatably connected to the protective cover 409 via a support plate. The trapezoidal screw also rotates through the lower part of the inner wall of the protective cover 409. Rotating the trapezoidal screw can adjust the position of the roller, causing the roller to squeeze the chain a402 and engage the chain a402 with the sprocket c407.

[0040] exist Figure 1In the process, the front part of the flower wheel 404 is connected to a sprocket d411 that drives the chain b412 to move. The outer side of the sprocket d411 is meshed with a chain b412 that drives the sprocket e413 to rotate. The chain b412 is meshed with the sprocket e413. The back of the sprocket e413 is connected to a gearbox 414 for changing the output direction. The gearbox 414 is connected to the frame 5, and the output end of the gearbox 414 is connected to a spur gear 415 for driving the screen cylinder 6 to rotate. The rear part of the spur gear 415 is meshed with an external gear ring 416 for transmitting power between the spur gear 415 and the screen cylinder 6. The external gear ring 416 is connected to the outer side of the screen cylinder 6.

[0041] In this potato harvester, the rotating flower wheel 404 also drives the sprocket d411 to rotate. Sprocket d411, via chain b412, drives sprocket e413 to rotate. Sprocket e413 then drives the gear set inside the gearbox 414 to rotate. The gearbox 414 then drives the spur gear 415 to rotate, which in turn drives the external gear ring 416 to rotate. This, in turn, causes the screen cylinder 6 to rotate within the frame 5, further screening the potatoes that have entered the screen cylinder 6 from the steel bar 405 to separate the soil.

[0042] exist Figure 1 , Figure 2 and Figure 7 In the process, the collecting mechanism 7 includes a support shaft 701 rotatably connected above the frame 5 via a bracket and bearings, and a hollow box 702 for temporarily storing potatoes is connected below the support shaft 701. The hollow box 702 is located on one side of the sieve cylinder 6.

[0043] In this potato harvester, the potatoes inside the sieve cylinder 6 roll to remove soil and then enter the hollow box 702 for temporary storage.

[0044] exist Figure 1 , Figure 2 and Figure 7 In the process, the end of the support shaft 701 is connected to a rocker arm 703 for transmission, and the other end of the rocker arm 703 is rotatably connected to a hydraulic rod 704 through a rotating shaft and bearing. The hydraulic rod 704 is rotatably connected above the frame 5 through a bracket, and the hydraulic rod 704 is used to flip and tilt the hollow box 702 to pour out potatoes.

[0045] When there are many potatoes in the hollow box 702, the potato harvester extends the hydraulic rod 704, which pushes the rocker arm 703, the hollow box 702 and the support shaft 701 to rotate, dumping the potatoes out of the hollow box 702 for manual collection and removal.

[0046] In summary: When using this potato harvester, firstly, the support frame 2 is connected to a tractor or other driving vehicle, and then the axle 31 is installed on the drive shaft of the tractor or other driving vehicle. The potato harvester is pulled by the tractor to walk on the land. The shovel 34 scoops up the soil and land and places it on the vibrating steel bar 405 to shake off the soil and return it to the land. The potatoes on the support frame 2 are conveyed by the steel bar 405 into the rolling screen cylinder 6, where the remaining soil is screened off and the potatoes fall into the hollow box 702 for collection. When there are many potatoes in the hollow box 702, the hydraulic rod 704 is extended to pour the potatoes out of the hollow box 702. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
